[0028] Reference Figure 1-Figure 4 , is an embodiment of the utility model, which provides a water conservancy project drainage device, comprising:

[0029] The main body 100 includes a drainage pipe 101, a shunt pipe 102, a return pipe 103 and a primary filter 104. The shunt pipe 102 and the return pipe 103 are both fixedly connected to the drainage pipe 101. The primary filter 104 is arranged between the shunt pipe 102 and the return pipe 103 and is fixedly connected to the inner wall of the drainage pipe 101. The primary filter 104 is in an arc shape.

[0030] The slag collecting mechanism 200 includes a primary valve 201, a slag collecting pipe 202, a collecting pipe 203, a secondary valve 204, a secondary filter 205 and a sealing threaded cover 206. The two ends of the primary valve 201 are fixedly connected to the diversion pipe 102 and the slag collecting pipe 202 respectively, the collecting pipe 203 is fixedly connected to the slag collecting pipe 202, the two ends of the secondary valve 204 are fixedly connected to the return pipe 103 and the collecting pipe 203 respectively, the secondary filter 205 is fixedly connected to the inner side of the collecting pipe 203, the end of the slag collecting pipe 202 close to the primary valve 201 is closed, and the end of the slag collecting pipe 202 close to the secondary valve 204 has an external thread and is threadedly connected to the sealing threaded cover 206;

[0031] The cleaning mechanism 300 includes a driving motor 301, a driving rod 302 and two groups of brush plate assemblies. The driving motor 301 is fixedly connected to the diverter pipe 102. The driving rod 302 is tightly connected to the drainage pipe 101 and is fixedly connected to the driving motor 301 shaft after passing through the drainage pipe 101. The two groups of brush plate assemblies are fixedly connected to the driving rod 302 and are symmetrically arranged. They are used to clean the primary filter 104 under the drive of the driving rod 302. The brush plate assembly includes a connecting rod 303 and a brush plate 304. The connecting rod 303 is vertically arranged in two groups with the driving rod 302. The two groups of connecting rods 303 are fixedly connected to the brush plates 304 and are symmetrically arranged. The ends of the two groups of connecting rods 303 away from the brush plates 304 are fixedly connected to the driving rod 302. The side of the connecting rod 303 close to the primary filter 104 has bristles that can touch the primary filter 104.

[0032] Among them, the collecting pipe 203 is generally bucket-shaped and gradually converges into a tubular shape at one end close to the secondary valve 204. The secondary filter screen 205 is matched with the inner wall size of one side of the collecting pipe 203 close to the slag collecting pipe 202, so that the area of ​​the secondary filter screen 205 is large enough to prevent the secondary filter screen 205 from being blocked by impurities. The arc center of the primary filter screen 104 is located on the axis of the diverter pipe 102, and the axes of the diverter pipe 102, the drive motor 301 and the drive rod 302 are arranged to coincide with each other, ensuring that the impurities cleared out by the brush plate 304 can enter the diverter pipe 102 with the water flow.

[0033] In addition, six groups of handles 207 are fixedly connected to the side wall of the sealing threaded cover 206. The six groups of handles 207 are evenly distributed around the sealing threaded cover 206. The six groups of handles 207 are used to facilitate personnel to rotate the sealing threaded cover 206. The driving rod 302, the connecting rod 303 and the brush plate 304 are all made of stainless steel. The stainless steel material can prevent rust. The bristles of the brush plate 304 are steel wire bristles. The steel wire bristles are high in strength, corrosion-resistant and have a strong cleaning effect.

[0034] Working principle: During drainage, the primary filter 104 intercepts impurities such as silt contained in the water flow, the diverter pipe 102 diverts the water flow, and the impurities follow the water flow through the diverter pipe 102 and the primary valve 201 in turn and enter the slag collecting pipe 202, the secondary filter 205 intercepts the impurities again, and the impurities finally remain in the slag collecting pipe 202, and the water flow entering the slag collecting pipe 202 passes through the collecting pipe 203, the secondary valve 204 and the return pipe 103 in turn and then flows into the drainage pipe 101;

[0035] The driving motor 301 drives the driving rod 302 to rotate, and the driving rod 302 drives the two sets of brush plates 304 to rotate through the four sets of connecting rods 303. During the rotation of the two sets of brush plates 304, the pores of the primary filter screen 104 are cleaned to prevent impurities from blocking the primary filter screen 104. The cleaned impurities enter the diversion pipe 102 under the action of gravity and water flow, and are finally input into the slag collecting pipe 202;

[0036] When cleaning the slag collecting pipe 202, close the first-level valve 201 and the second-level valve 204 in turn, the drainage pipe 101 performs drainage operations normally, the slag collecting pipe 202 is closed, and the sealing threaded cover 206 is turned and removed by the handle 207 to clean the inside of the slag collecting pipe 202. After cleaning, reset the sealing threaded cover 206, open the second-level valve 204 and the first-level valve 201, and during cleaning, the impurities retained by the first-level filter screen 104 enter the slag collecting pipe 202 with the water flow, and the device can continue to be used.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
