Description

Technical Field

[0001] The utility model relates to the field of water retaining dams, in particular to an anti-seepage and drainage structure of a water retaining dam. Background Art

[0002] A dam is a water retaining structure that intercepts water flow in rivers and canals to raise the water level or regulate the flow. It is used for flood control, water supply, irrigation, hydroelectric power generation, improved navigation, etc. Commonly used dams include rubber dams, sluice gates and flap gate dams. The height of the dam determines the depth of water storage, and it is inconvenient to adjust the water storage depth according to needs during actual use.

[0003] A Chinese patent with the Chinese patent announcement number CN213417744U discloses an adjustable water retaining dam for water conservancy and hydropower engineering. A worker drives a motor, and the motor drives a double-headed threaded rod supported by a fixed block to rotate. The two ends of the double-headed threaded rod respectively drive two sliders and a valve plate to move toward or away from each other, so as to achieve the effect of adjusting the flow of river water through the water channel. The worker unscrews the bolts and withdraws the bolts from the positioning holes to disassemble the valve plate for cleaning.

[0004] In the above technical solution, the required installation size is relatively large, and it is not convenient to adjust the depth of water storage according to usage needs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and proposes an anti-seepage drainage structure of a water retaining dam which can adjust the depth of water storage in multiple gears and has a small installation size.

[0009] A connecting platform is arranged on the foundation and the dam body and is located at the drainage outlet;

[0010] A plurality of sealing plates are stacked and slidably arranged on the foundation in sequence and located at the drain outlet; a limiting mechanism for limiting the sealing plates is arranged on the connecting platform.

[0011] Preferably, the dam body comprises a slope arranged on the foundation; drainage grooves are arranged at both upper and lower ends of the slope, and a guide groove for connecting the two drainage grooves is arranged on the slope.

[0012] Preferably, the dam body further comprises anti-skid steps arranged obliquely.

[0013] Preferably, the limiting mechanism includes two limiting rods which are rotatably arranged on the connecting platform, and a rotating mechanism which is arranged on the connecting platform and is used to drive the limiting rods to rotate.

[0015] Preferably, the limiting mechanism further comprises a support rod arranged on the foundation; the limiting rod abuts against the support rod.

[0016] Preferably, a clamping platform and a lifting hole are provided on the sealing plate; the lifting hole is located at the upper part of the sealing plate.

[0017] Compared with the prior art, the utility model has the following beneficial technical effects:

[0018] In the utility model, the number of sealing plates is selected according to the height of water storage required, and the sealing plates are guided by guide grooves so that the sealing plates can be securely blocked at the drain outlets, and the water on the sealing plates at high places will overflow from above the sealing plates, and drainage can be conveniently carried out through the drainage steps. After an accidental fall into the water, the water level can be gradually reduced through the drainage steps, which is convenient for self-rescue; redundant sealing plates are fixed by limiting mechanisms, and when they are needed, the limiting mechanisms are used to release the limiting mechanisms, so that the sealing plates can be placed in turn on the sealing plates below, so that they can be freely selected according to the rainy season.
