The invention discloses a tidal type water inlet pool pressure difference induced upwelling multiplication artificial fish reef system. A water inlet grid is arranged above the wall of the pool facing the side facing the tide. When the tide is high, the seawater passes through the water inlet grid. The gap of the grid enters water into the pool; the outlet pipe is buried and arranged in the bottom mud layer close to the wall of the pool, and above the outlet pipe is provided with a plurality of spray holes located under the surface of the bottom mud; between the outlet pipe and the pool are installed Pressure switch, when the gravity pressure difference of the seawater surface inside and outside the pool reaches a certain range, the pressure switch is turned on, the water body in the pool flows out, and the water column spurts upwards from the nozzle hole, bringing the nutrients in the bottom layer to the upper water surface, forming an upwelling around the artificial reef . Compared with the prior art, the present invention does not need to use a water pump to replace the water body of the pool, avoids the long-term maintenance of the water pump equipment, saves manpower and material resources, and is beneficial to the proliferation and ecological protection of coastal sea areas. It has a good application prospect.

Description

Tidal type intake pool pressure reduction is induced the propagation artificial fish shelter system of upwelling

Technical field

This patent relates to the artificial fish shelter manufacture technology field, particularly relate to a kind ofly utilize that flood tide and realize that the pond intakes automatically, the inside and outside water level pressure reduction in pond during ebb tide is realized automatic water outlet, the technology of pond and artificial fish shelter coupling construction upwelling.

Background technology

The related pond of this patent can be swimming pool, offshore recreational facilities etc.This sentences swimming pool is example.

The seashore swimming pool is important coastal waters recreational facilities, attracts numerous visitors to accumulate in to relieve summer heat leisurely here and plays, and be good body-building, public place of entertainment.At present, most of swimming pools all need the manual adjustment Inlet and outlet water, have expended manpower; In addition,, utilize water pump to change the process of water, consumed the energy in order to ensure water quality health.

Artificial fish shelter is the structure that artificially is provided with in water, its objective is and improves water area ecological environment, builds the good environment that aquatic organism perches, and it need utilize the upwelling motion for fish etc. provide the equipment of forage, reaches propagation and improves the purpose of catch.That is, upwelling is the ocean current that directly rises with the lower edge from the top layer, can take the top layer to a large amount of nutrients in sea water in profundal zone (phosphate, nitrate etc.) to, and abundant bait is provided, and attracts the shoal of fish to come to look for food.

But the above-mentioned immediate offshore areas of mentioning such as seawater swimming pool are slow owing to seawater movement, thereby can only produce more weak upwelling motion.

The present situation in present technique field is to be unfavorable for that in nearshore waters or pool environments artificial fish shelter plays a role and the improvement of water area ecological environment.

Summary of the invention

Based on problems of the prior art, the present invention proposes the propagation artificial fish shelter system that a kind of tidal type intake pool pressure reduction is induced upwelling, utilizes tidal level to change and realizes that the pond intakes, utilizes the height of water to realize the technology that upwelling is built in automatic water outlet, pond and artificial fish shelter coupling automatically.

The present invention proposes a kind of tidal type intake pool pressure reduction and induce the propagation artificial fish shelter system of upwelling, this system comprisespond 10 and artificial fish shelter 2, and immediate offshore area is built in described pond in, wherein:

Artificial fish shelter 2 is positioned at sediment layer 1 upper strata;

Be provided withtrash rack 3 towards morning and evening tides above the pond of side body ofwall 8, at the incoming tide, seawater is intake to the pond by the space oftrash rack 3, particulate pollutant in thetrash rack 3 interception water;

Outlet pipe 6 is buried and is arranged in the close sediment layer 1 of pond body ofwall 8, and described outlet pipe 6 tops are provided with a plurality of spray orifices, and these spray orifices are positioned under the bed mud top layer; Between outlet pipe 6 and thepond 10pressure switch 7 is housed, when seawater liquid level gravity pressure reduction reaches certain limit inside and outside the pond,pressure switch 7 is opened automatically, water body flows out in the pond, water column is upwards gushed by spray orifice, take the nutriment of bottom to topmost surface, around artificial fish shelter 2, form upwelling;

Described basin bottom is designed at the bottom of the ramp type pond, comprises abottom ramp 9.

The height at describedbottom ramp 9 two ends needs decision by water outlet and desilting, and slope length L * equals pond body total length L and deducts outlet pipe 6 diameter D, and the slope width is identical with pond width B size.

Described outlet pipe 6 adopts plastic material.

Compared with prior art, the water body that the present invention need not to utilize water pump to carry out the pond is changed, and has avoided long-term pump equipment maintenance work, uses manpower and material resources sparingly; Utilize the exiting water process in pond, near artificial fish shelter, form upwelling, help immediate offshore area propagation and ecological protection.Therefore, this technology has good application prospects at coastal waters recreational facilities and marine ecology protection field.

Embodiment

Below in conjunction with accompanying drawing, further describe specific implementation of the present invention.

With reference to Fig. 1 and Fig. 3, pond of the present invention (is example with the swimming pool) 10 and artificial fish shelter coupling technique are applied to immediate offshore area usually, and basin bottom is used the concrete masonry units sloping, the height h ofbottom ramp 9₁, h₂Need decision by water outlet and desilting, slope length L * equals pond body total length L and deducts outlet pipe 6 diameter D, and the slope width is identical with pond width B size.Build up after thebottom ramp 9, use reinforcing bar, concreting pond body ofwall 8 again, body ofwall 8 height H are determined that by fluctuation tidal level difference pond width B and length L are determined that by the pond appearance demand in pond the pond holds by pond function (swimming demand), all spray orifice flows and fountain time definite.

Fig. 3 is the normal cross-section schematic diagram of pond (swimming pool) device.Be provided withtrash rack 3 towards morning and evening tides above the body of wall of the pond of a side, at the incoming tide, seawater is intake topond 10 by the space oftrash rack 3, andgrid 3 can be tackled particulate pollutant in the water.When tidal level is lower thangrid 3 height, stop the inside and outside current exchange in pond.
