The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 3, a device suitable for removing supernatant in a mud pit comprises a hose 3 and a floating assembly 12, wherein the floating assembly 12 is provided with a through hole for allowing the hose 3 to pass through, one end of the hose 3 is communicated with a water pump water suction port 2 of a water pump 1, the other end of the hose 3 passes through the through hole and then is communicated with a water suction port 5, the water suction port 5 comprises a top cover 51 connected with the hose 3 in a flange manner, a water suction pipe 52 is clamped below the top cover 51, the lower part of the water suction pipe 52 is a bottom water inlet 522, and a filter screen is arranged in the bottom water inlet 522.

Compared with the existing steel pipe, the hose 3 has better flexibility, so that along with the change of the height of the supernatant water surface 11, the hose 3 can also move up and down along with the floating assembly 12 to adapt to the change of the water surface, and thus the distance from the water suction port 5 to the water surface and the mud layer can be adjusted.

The floating assembly 12 is formed by sequentially connecting four square floating assemblies 12 through metal wires 8, and a through hole for allowing the hose 3 to pass through is formed in the middle of each square floating assembly 12.

The float 4 is a hollow sphere.

The distance between the floating assembly 12 and the water intake 5 can be adjusted according to actual needs. By utilizing the balance of the buoyancy and the gravity of the floating assembly 12, the floating assembly 12 can always float on the supernatant water surface 11 and is not changed due to the change of the water surface height. So that the water suction port 5 can still be kept between the supernatant water surface 22 and the mud layer 10 along with the movement of the water surface, and can not extend into the mud layer 10 and leave the supernatant water surface 11.

The top cover 51 is a hollow cylinder, a fixture block 512 is fixed on the upper part of the inner wall of the top cover 51, and a clamping groove 513 is formed in the top surface of the fixture block 512 downwards.

Three clamping blocks 512 which are uniformly distributed are fixed on the upper part of the inner wall of the top cover 51.

The water suction port 5 is connected with the hose 3 by flanges, so that when the water suction port 5 is blocked or needs to be replaced for a long time, the water suction port can be detached and installed very conveniently and quickly.

A hook 5212 matched with the clamping groove 513 is fixed on the outer wall of the top of the water suction pipe 52, the hook 5212 comprises a transverse portion 5211 with one end fixed with the water suction pipe 52, the other end of the transverse portion 5211 is hinged with a vertical portion 5213, and the vertical portion 5213 extends into the clamping groove 513.

The upper part of the suction pipe 52 is an upper elastic pipe 523, and the upper elastic pipe 523 is made of an elastic material. The elastic material is preferably an elastic rubber.

The upper elastic tube 52 is made of an elastic material, so that the upper elastic tube 52 can be deformed under the action of manual extrusion, and the upper elastic tube 52 can be conveniently separated from the top cover 51.

The transverse part 5211 is hinged to the vertical part 5213, and when the water suction pipe 52 needs to be clamped with the top cover 51, the vertical part 5213 is extended into the clamping groove 513 to realize clamping; when it is desired to remove barrel 52 from top cover 51, barrel 52 is pushed upward, causing upstand 5213 to move upward away from catch 513. At this point, barrel 52 is squeezed, causing barrel 52 to deform slightly inwardly until barrel 52 is removed from cap 51.

The top cover 51 and the suction pipe 52 are clamped, so that the suction pipe 52 can be conveniently detached and cleaned, when too many impurities accumulated on the filter screen need to be cleaned, the suction pipe 52 only needs to be detached, the whole suction opening 5 does not need to be detached from the hose 3, and the replacement is convenient.

The bottom water inlet 522 is a cone with the inner diameter gradually increasing from the top to the bottom, and a first filter screen 5221, a second filter screen 5222 and a third filter screen 5223 are sequentially arranged in the bottom water inlet 522 from top to bottom.

The filter holes of the first filter screen 5221, the second filter screen 5222 and the third filter screen 5223 are gradually enlarged.

The multilayer filter screen plays the effect of tiny dregs or impurity in the filtration supernatant, guarantees to have no impurity in the supernatant that gets into water pump 1 from water sucking mouth 5, prevents to damage or block up the water pump.

The floating component 12 is positioned on the supernatant water surface 11, and the water suction port 5 is positioned between the supernatant water surface 11 and the mud layer 10.

The water suction port 5 can change along with the change of the liquid level in the mud pit 9, the effective volume in the mud pit 9 can be greatly utilized, the risk of blocking the water pump 1 is reduced, and the blocking of silt to the water suction port 5 can be eliminated as much as possible.

The height of the water suction port 5 changes along with the change of the height of the water surface 11 of the supernatant, so that the water suction port 5 can fully absorb the supernatant and cannot contact the mud layer 9 to cause the blockage of the water suction port 5 and the water pump.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
