[0029] Refer to the attached Figs. 1-3 A water conservancy construction drainage device, comprising:

[0030] Drainage tank 1, the middle part is provided with a drainage channel 2, and one desilting port 3 is formed in each side wall;One desilting channel 4 is arranged on the outer side of the side wall of the drainage tank 1;

[0031] The guard plate 5 is arranged on the outer side of the side wall of the drainage tank 1, and the guard plate 5 is arranged on the outer side of the desilting channel 4;The top of the guard plate 5 is provided with two symmetrical connecting plates 6, and the connecting plates 6 are fixed with the side wall of the desilting channel 4 through the locking assembly;The inner side of the guard plate 5 is further provided with two sealing plates 7;

[0032] The first filter screen 8 is arranged on the top and bottom of the drainage tank 1;

[0033] The second filter screen 9 is arranged in the drainage tank 1, and located between the two first filter screens 8;

[0034] The water pump 10 is located above the drainage tank 1, and the outer side of the water pump 10 is provided with a protective shell 11 and connected with a water pumping pipe 12;The protective shell 11 can protect the water pump 10 from being collided by hard objects during underwater operation.

[0035] In the embodiment, the first filter screen 8 is horizontally arranged, and the second filter screen 9 is inclinedly arranged;The upper end of the second filter screen 9 is located above the corresponding desilting port 3, and the lower end of the second filter screen 9 is located below the corresponding desilting port 3;The first filter screen 8 arranged at the bottom of the drainage tank 1 plays a first filtering role, then the water flow enters the drainage channel 2 and impacts the inclined second filter screen 9;At this time, part of the blocked silt will flow upward along the bottom inclined surface of the second filter screen 9 with the water flow, and finally enter the silt pipeline from the corresponding desilting port 3;The silt not blocked by the second filter screen 9 will be blocked by the first filter screen 8 arranged at the top of the drainage tank 1, and then flow downward along the top inclined surface of the second filter screen 9 under the backflow impact of the internal water flow and the action of gravity, and finally enter the silt pipeline on the other side from the corresponding desilting port 3.

[0036] The height of the uppermost sealing plate 7 is higher than the height of the sediment outlet 3, and the height of the lowermost sealing plate 7 is lower than the height of the sediment outlet 3. The two sealing plates 7 can separate the sediment channel 4 into a containing space for temporarily collecting the sediment entering from the sediment outlet 3.

[0037] The locking assembly comprises a limiting plate 13, a limiting column 14 and a locking nut 15. The limiting plate 13 is in the shape of inverted L, and the top horizontal plate of the limiting plate 13 is arranged on the corresponding connecting plate 6. The limiting column 14 is provided with a thread at one end and is screwed with the locking nut 15, and the other end of the limiting column 14 is welded with the vertical plate of the limiting plate 13. When the limiting column 14 is locked with the locking nut 15, the position of the guard plate 5 is fixed and the guard plate 5 cannot be easily rotated. When the locking nut 15 is loosened, the top horizontal plate of the limiting plate 13 is no longer arranged on the corresponding connecting plate 6 by pushing the limiting column 14, and at this time, the guard plate 5 can be rotated, the bottom of the guard plate 5 is opened, and the accumulated sediment in the sediment channel 4 can be cleaned.

[0038] On the other hand, the bottom of the drainage tank 1 is provided with a U-shaped pad plate 16, the front and rear ends of the pad plate 16 are fixed with the lower parts of the two side walls of the sediment channel 4 through bolts, and a water inlet channel 17 is arranged between the bottom of the pad plate 16 and the bottom of the drainage tank 1. When the water pump 10 is started, the water with sediment at the bottom is pumped into the drainage channel 2 in the drainage tank 1 from the water inlet channel 17, filtered through the multiple filter plates, and finally discharged from the water pump 12. The water inlet channel 17 has two water inlets, which can facilitate the water to enter from both sides of the drainage tank 1, and is beneficial to speed up the drainage efficiency.

[0039] In the actual drainage operation process, when a large amount of sediment accumulates in the drainage tank 1 and the sediment pipelines on both sides, the drainage efficiency of the water pump 10 will be affected. The staff can use tools to lift the drainage tank 1 and the water pump 10 out of the water, then loosen the locking nut 15 of the locking assembly, so that the guard plate 5 can be rotated along the limiting column 14, the bottom of the sediment channel 4 is opened and exposed to the outside, then the staff can clean the accumulated sediment in the sediment channel 4 by using tools or a high-pressure water gun. When the sediment in the sediment channel 4 is cleaned, the guard plate 5 can be rotated back to the initial state, the locking nut 15 is tightened, the sediment channel 4 is kept in a closed state, and then the drainage tank 1 and the water pump 10 are placed below the water surface to continue the water pumping operation.

[0040] The drainage device for water conservancy construction has the advantages that the sediment channel 4 is arranged on both sides of the drainage tank 1, and the multiple filter screens are matched, so that most of the sediment entering the drainage tank 1 can be guided into the sediment channel 4 in the water pumping process, which is convenient for subsequent cleaning, is beneficial to eliminate the safety hazard that the filter plates are blocked, avoids affecting the efficiency of subsequent drainage operation, is very practical, and has good market application prospect.
