The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Reference Figures 1 to 3 As shown, the present invention provides a drainage device for underground engineering operations, including: a water passing box 1, a crushing mechanism 2, and a scraper plate 3.

[0026] In this embodiment, the water transfer box 1 is in the shape of a long strip. The water transfer box 1 has a first end and a second end opposite to each other. The first end is provided with a water inlet a. The water inlet is connected to the upstream drainage pipe through a flange.

[0027] The second end is provided with a water outlet which is connected to a downstream drainage pipe through a flange.

[0028] A plurality of partitions 11 are provided in the water tank 1. The partitions 11 are provided with a plurality of filtering holes. The plurality of partitions 11 are arranged at intervals along the length direction of the water tank 1. In this embodiment, the aperture of the filtering holes gradually decreases from the water inlet to the water outlet.

[0029] The crushing mechanism 2 includes a rotating shaft 21 , a motor 22 , a limb 23 , and a striking rod 24 .

[0030] The rotating shaft 21 is vertically arranged in the water tank. Specifically, the rotating shaft 21 is rotatably installed between the water inlet and the first partition 11.

[0031] A motor 22 is installed on the water tank 1. The motor 22 is connected to the rotating shaft 21 in a transmission manner.

[0032] As a preferred embodiment, the output shaft of the motor 22 is coaxially connected to the rotating shaft 21 .

[0033] The rotating shaft 21 is connected to a plurality of limbs 23. The plurality of limbs 23 are arranged in the vertical direction. Each limb 23 includes a plurality of limbs, and the plurality of limbs are arranged at equal intervals along the circumferential direction of the rotating shaft. In this embodiment, three limbs are arranged on the rotating shaft. Each limb includes four limbs.

[0034] The two opposite sides of the limb rod 23 are respectively connected with a plurality of striking rods 24. The plurality of striking rods 24 are arranged at intervals along the length direction of the limb rod 23.

[0035] The striking rod 24 on the end of the limb 23 away from the rotating shaft 21 is attached to the wall of the water tank 1. The striking rod 24 on the limb 23 at the upper end of the rotating shaft 21 is attached to the top wall of the water tank 1. The striking rod 24 on the limb 23 at the lower end of the rotating shaft 21 is attached to the bottom wall of the water tank 1.

[0036] In this embodiment, a plurality of limbs are arranged on the cross section of the water tank. After the accumulated water containing silt in the underground water pit enters the first compartment of the first partition and the side of the water tank through the water inlet, the motor drives the rotating shaft to rotate and drive the limbs and the striking rod to rotate to break up the silt blocks in the first compartment. The silt with small particle size enters the next compartment through the filter hole of the first partition, while the silt with large particle size remains on the first partition. The silt in the next compartment is filtered through the filter hole of the next partition, so that the accumulated water containing small particle size is drained through the downstream drainage pipe to avoid blockage of the drainage pipe.

[0037] As a preferred embodiment, the bottom wall is provided with a plurality of drain outlets, each of which is provided with a valve 12. Specifically, each chamber is provided with a drain outlet, and the precipitated silt can be discharged through the drain outlet.

[0038] In this embodiment, there are multiple scraper plates 3. The scraper plates 3 are attached to opposite sides of the partition 11. The top wall is provided with multiple through holes. Hanging rods 31 are movably inserted into the multiple through holes. The lower end of the hanging rod 31 is connected to the scraper plate 3. The upper ends of the multiple hanging rods 31 are connected to the cross beam 32. A driving structure 33 is installed on the water tank 1. The driving structure 33 is used to lift the cross beam 32.

[0039] See also Figure 2 and Figure 3 As shown, in this embodiment, the driving structure 33 includes: a bracket 331 , a screw rod 332 , and a hand wheel 333 .

The cross beam 32 is provided with a vertically arranged threaded hole. The screw rod 332 is screwed into the threaded hole. The upper end of the screw rod 332 is coaxially connected with a hand wheel 333.

[0041] The hand wheel is rotated to drive the screw to rotate, so that the beam rises and falls in the vertical direction. When the beam rises and falls, the scraper plate rises and falls along the side of the partition, and then the mud and sand attached to the partition are scraped off and gathered on the bottom wall of the water tank, and then discharged through the sewage outlet.

[0042] As a preferred embodiment, the thickness of the scraper plate gradually decreases from one side of the scraper plate close to the partition plate 11 to the other side of the scraper plate away from the partition plate 11 .

[0043] In this embodiment, the bottom surface of the scraper plate is arc-shaped.

[0044] The drainage device for underground engineering operations of the present invention can crush and break up larger or agglomerated silt by setting a crushing mechanism, thereby avoiding the accumulation of larger silt blocks, and then filtering through multiple partitions, so that the accumulated water will not be blocked when discharged through the downstream drainage pipe, and at the same time, it also provides convenience for the subsequent scraper operation. The drainage device for underground engineering operations of the present invention can clean the partition by setting a scraper, avoiding blockage caused by excessive silt accumulation during long-term use, making the cleaning operation more time-saving and labor-saving.
