[0024] As shown in Figure 1 and Figure 3 A trash rack for water conservancy projects, comprising two pier walls 1, the opposite sides of the two pier walls 1 are each provided with a fixed slot 22, a trash rack 2 is arranged between the two pier walls 1, the two ends of the trash rack 2 are each fixed in the two fixed slots 22, the trash rack 2 comprises a frame 3 and a plurality of bars 4 welded at equal intervals on the frame 3, a storage gap 5 is arranged between the adjacent two bars 4, a trash plate 6 is slidably arranged in the storage gap 5, one end of the plurality of trash plates 6 each extends out of the storage gap 5 and is connected to each other, and the opposite sides of the two pier walls 1 are each fixed with a driving structure for driving the trash plate 6 to slide in the vertical direction.

[0025] Among them, the two sides of the trash plate 6 are in abutment with the side walls of the two bars 4.

[0026] When the staff needs to clean the trash rack 2, only the driving structure is started to drive the trash plate 6 to slide along the storage gap 5 from the river bottom to the top surface of the trash rack 2, and the trash accumulated on the surface of the trash plate 6 and the trash stored in the storage gap 5 also slide to the top surface of the trash rack 2 under the pushing of the trash plate 6 until the driving structure drives the trash plate 6 to move to the top surface of the trash rack 2, so that the staff can put the trash collected on the surface of the trash plate 6 into a garbage bag to complete the cleaning of the trash rack 2. Through the structure of the present application, the trash in the plurality of storage gaps 5 can be collected on the top of the trash rack 2 at one time by moving the trash plate 6, without sequentially scraping off the storage gaps 5, not only saving time and effort, but also reducing cleaning cost, and large-scale cleaning can be completed in a short time, greatly improving the cleaning efficiency and being very convenient.

[0027] The two sides of the trash blocking plate 6 are in abutment with the side walls of the two side grids 4, so that when the dirt is adhered or adsorbed on the side walls of the side grids 4, the trash blocking plate 6 can shovel and scrape off the dirt in the movement process, so that the dirt in the dirt storage gap 5 is further removed, the cleaning efficiency is improved, and it is very convenient.

[0028] As shown in Figure 4 and Figure 5 , the two opposite sides of the pier wall 1 are provided with an embedded groove 12, the driving structure includes a lead screw 7 rotatably connected in the embedded groove 12, a plurality of fixed blocks 13 are integrally formed in the embedded groove 12, the two ends of the lead screw 7 are threadedly connected in the fixed blocks 13, a ball nut 9 is threadedly connected on the lead screw 7, a sliding plate 10 is arranged on one side of the ball nut 9, the ball nut 9 and the sliding plate 10 are connected through a connecting block 23, a sliding groove 19 for sliding of the connecting block 23 is formed in the embedded groove 12 in the vertical direction, the two ends of the sliding plate 10 slide on the side wall of the pier wall 1, the sliding plate 10 is connected with the trash blocking plate 6, and the top of the pier wall 1 is fixed with a driving source 8. In this embodiment, the driving source 8 is a motor, and the output shaft of the motor is connected with the top of the lead screw 7.

[0029] When the motor is started, the motor drives the lead screw 7 to rotate, at this time, the two ends of the sliding plate 10 are limited by the side wall of the pier wall 1, so that the connecting block 23 can only slide in the sliding groove 19 along the length direction of the sliding groove 19, and at the same time, the sliding plate 10 can only slide on the side wall of the pier wall 1, so that the ball nut 9 cannot rotate with the lead screw 7, but can only move axially along the length direction of the lead screw 7, thereby driving the sliding plate 10 to slide, and driving the trash blocking plate 6 to move up and down along the dirt storage gap 5. By moving up and down of the trash blocking plate 6 in the dirt storage gap 5, the dirt storage gap 5 can be cleaned, which is simple and very convenient to operate.

[0030] As shown in Figure 5 , the side of the sliding plate 10 close to the trash blocking plate 6 is fixed with a connecting rod 11, the connecting rod 11 is detachably connected with the trash blocking plate 6, the trash blocking plate 6 is integrally formed with a fixing seat 14, the fixing seat 14 is provided with a groove 15 for clamping the end of the connecting rod 11, and a threaded rod 16 is threadedly connected on the fixing seat 14. The connecting rod 11 is radially provided with a threaded hole 17 for clamping the threaded rod 16.

[0031] Among them, one end of the threaded rod 16 is integrally formed with a rotating block 18.

[0032] When the trash screen 6 needs to be replaced or cleaned, the trash screen 6 is disassembled by moving the trash screen 2 to the uppermost position, rotating the rotating block 18 to rotate the threaded rod 16 along the threaded hole 17 until the threaded rod 16 is disconnected from the connecting rod 11, releasing the threaded rod 16 from the connecting rod 11, then moving the trash screen 6 away from the connecting rod 11, so that the connecting rod 11 is disconnected from the groove 15, and the trash screen 6 is disassembled for replacement, which is very convenient.

[0033] When the trash screen 6 needs to be installed, the connecting rod 11 is first inserted into the groove 15, then the rotating block 18 is rotated to insert the threaded rod 16 into the threaded hole 17, until the rotating block 18 abuts against the outer wall of the fixed seat 14 to tighten, and the trash screen 6 is fixed with the connecting rod 11.

[0034] As shown in Figure 4 The opposite sides of the chute 19 are fixed with brushes 20.

[0035] The brushes 20 prevent large pieces of trash in the water flow from entering the recess 12 through the chute 19, ensuring normal rotation of the lead screw 7, thereby improving the stability of the trash screen 6 when sliding and cleaning trash, and the soft material of the brushes 20 allows the brushes 20 to not hinder the sliding of the connecting block 23 when the connecting block 23 slides in the chute 19, thereby effectively isolating the external environment from the inside of the recess 12.

[0036] As shown in Figure 1 The motor is sleeved with a waterproof box 21.

[0037] The waterproof box 21 prevents rainwater, dust and other external substances from entering the motor, avoids causing short circuit of the motor, prolongs the service life of the motor, ensures stable rotation of the lead screw 7, and ensures smooth up and down movement of the trash screen 6 for cleaning.
