[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 , a stainless steel drain trough, comprising:

[0025] The drainage trough body 1 and the cover body 12 are provided with a plurality of water-permeable holes 2 on the periphery of the drainage trough body 1 and a drainage port 3 is provided at the bottom. The drainage port 3 is connected to the input end of an external self-priming pump. The cover body 12 is installed on the drainage trough body 1.

[0026] The filtering mechanism includes a sliding block 5, an extrusion assembly and a filter screen plate 9. Two sliding blocks 5 are connected to the inner circumference of the drainage trough body 1. A snap-in groove 6 is provided on the opposite side of the two sliding blocks 5. The two snap-in grooves 6 are connected to the extrusion assembly. The output ends of the two extrusion assemblies are abutted against the same filter screen plate 9. The filter screen plate 9 abuts against the inner wall of the drainage trough body 1 and cooperates with multiple water-permeable holes 2.

[0027] The extrusion assembly includes an extrusion bar 7 and an extrusion spring 8. The two extrusion bars 7 are slidably connected in the two clamping grooves 6 one by one. The extrusion spring 8 is fixedly connected between the extrusion bar 7 and the inner wall of the corresponding clamping groove 6. The extrusion bar 7 is pressed against the side wall of the filter screen plate 9.

[0028] Two sliding grooves 4 are provided on the inner circumference of the drainage groove body 1 , and two sliding blocks 5 are slidably connected in the two sliding grooves 4 in a one-to-one correspondence.

[0029] The top and bottom ends of the sliding block 5 are both fixedly connected with a buffer spring 10 , and one end of the buffer spring 10 away from the sliding block 5 is fixedly connected to the inner wall of the sliding groove 4 .

[0030] A disturbance plate 11 is fixedly connected to the side of the sliding block 5 away from the drainage trough body 1 , and the disturbance plate 11 is perpendicular to the inner wall of the drainage trough body 1 .

[0031] The filter screen plate 9 is provided with a plurality of filter holes, and the inner diameters of the plurality of filter holes are smaller than the inner diameter of the water permeable hole 2 .

[0032] The operating principle of the utility model is now described as follows:

[0033] When there is a lot of water in the foundation pit, the drainage trough body 1 is placed in the foundation pit. The water in the foundation pit passes through the water-permeable holes 2 and then enters the drainage trough body 1 through the filter holes on the filter screen plate 9, thereby forming a secondary filtering effect on the debris in the water to prevent the debris from affecting the subsequent pumping.

[0034] After the accumulated water is collected in the drainage trough body 1, the external self-priming pump starts working, and its output end extracts the accumulated water inside the drainage trough body 1 through the drainage port 3 to form a drainage effect;

[0035] During the drainage process, the flow of water in the drainage trough 1 pushes the disturbance plate 11, and cooperates with the buffer spring 10 to drive the filter screen plate 9 to fluctuate up and down through the sliding block 5 and the extrusion assembly, so that the surface of the filter screen plate 9 and the edge of the water permeable hole 2 produce friction, which has a removal effect on the debris adhered to the surface of the filter screen plate 9, effectively preventing the debris from adhering to the surface of the filter screen plate 9 and clogging the filter holes, thereby ensuring that the filter screen plate 9 works normally and reducing the burden of the staff to clean the filter screen plate 9;

[0036] When the filter screen plate 9 needs to be cleaned, the cover body 12 is opened and the filter screen plate 9 can be directly pulled out from between the two extrusion strips 7, which facilitates the removal and installation of the filter screen plate 9.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
