Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a river channel desilting box for water conservancy projects. Background Art

[0002] Water conservancy projects refer to various types of projects such as flood control, drainage, irrigation, hydropower generation, water diversion, tidal flat management, soil and water conservation, water resources protection, and their supporting and ancillary projects.

[0003] Dredging in water conservancy projects can effectively remove underwater sediments. In water conservancy projects, the treatment effect of silt is not good. When some filtering equipment is working, long-term use can easily cause silt to clog the filter holes, resulting in a decrease in filtering effect. Utility Model Content

[0004] The purpose of the utility model is to provide a river channel desilting box for a water conservancy project, which is used to overcome the above-mentioned defects in the prior art.

[0005] According to the utility model, a river channel desilting box for a water conservancy project comprises a silt box, a silt outlet is arranged at the upper end of the silt box, cavities are arranged at the left and right ends of the silt box, a telescopic slide is slidably connected to the silt box, the telescopic slide comprises a sliding plate which is slidably matched with the silt box, a sliding frame is slidably connected to the sliding plate, a pressure roller is rotatably connected between the two sliding frames, the pressure roller is operated by a motor, two left-right symmetrical slide grooves are arranged on the silt box, racks are fixed on the two slide grooves, an electric gear is rotatably connected to the sliding plate, and the electric gear is rotatably connected to the rack The sliding plate and the sliding frame are meshed, and evenly distributed spring telescopic rods are connected between the sliding plate and the sliding frame. A lifting plate that can slide up and down is provided on the open cavity. Fixed clamping rods are fixed on the two sliding plates, and the fixed clamping rods are clamped with the lifting plates. The front and rear ends of the pressure roller are rotatably matched with retaining rings, and the retaining rings abut against the inner end surface of the sludge box. The left and right ends of the sludge box are fixed with mounting frames, and a detachable water filter box is fixed on the mounting frame. The water filter box is opened up and down, and a filter screen is provided on the water filter box. The spring telescopic rod is a multi-section telescopic rod, and the elastic force at each section of the telescopic rod is the same.

[0006] The beneficial effects of the utility model are:

[0007] The pressure roller rolls back and forth in the sludge box, and the supporting force of the spring telescopic rod squeezes the silt and other debris in the sludge box to make them sink to the bottom. At the same time, under the opening setting of the cavity, the water that enters the sludge box synchronously with the silt flows from the cavity to the filter water box, and is filtered through the filter screen on the filter water box. The water flows through the upper and lower openings of the filtered water tank and flows back to the river channel. The silt is collected in the sludge box and squeezed by the pressure roller, which can effectively prevent the filter screen from being blocked. The lifting plate rises synchronously with the rise of the pressure roller to maintain the use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a water conservancy project river channel desilting box includes a silt box 10, a silt outlet is provided at the upper end of the silt box 10, and an opening 11 is provided at the left and right ends of the silt box 10. A telescopic slide 14 is slidably connected to the silt box 10, and the telescopic slide 14 includes a sliding plate 15 that slides with the silt box 10 and a sliding frame 16 that is slidably connected to the sliding plate 15. A pressure roller 13 is rotatably connected between the two sliding frames 16, and the pressure roller 13 is operated by a motor. Two left-right symmetrical chute grooves are provided on the silt box 10, and racks 24 are fixed on the two chute grooves. An electric gear 25 is rotatably connected to the sliding plate 15, and the electric gear 25 and the gear The strips 24 are meshed, and a uniformly distributed spring telescopic rod 17 is connected between the sliding plate 15 and the sliding frame 16. A lifting plate 21 that can slide up and down is provided on the open cavity 11. Fixed clamping rods 22 are fixed on the two sliding plates 15, and the fixed clamping rods 22 are clamped with the lifting plates 21. The front and rear ends of the pressure roller 13 are rotatably matched with retaining rings 20, and the retaining rings 20 abut against the inner end surface of the sludge box 10. The left and right ends of the sludge box 10 are fixed with mounting frames 23, and a detachable water filter box 12 is fixed on the mounting frame 23. The water filter box 12 is opened up and down, and a filter screen 18 is provided on the water filter box 12. The spring telescopic rod 17 is a multi-section telescopic rod, and the elastic force at each section of the telescopic rod is the same;

[0021] A sludge outlet is provided at the upper opening of the sludge box 10, and the sludge and the water carried are sprayed into the sludge box 10 through the sludge outlet. The electric gear 25 on the sliding plate 15 is powered on, and the electric gear 25 rotates through the motor. Under the meshing of the electric gear 25 and the rack 24, the motor controls the electric gear 25 to rotate forward and reverse, thereby controlling the telescopic slide 14 to reciprocate back and forth as a whole. The motor at the pressure roller 13 is operated to rotate the pressure roller 13, and the telescopic slide 14 drives the pressure roller 13 to reciprocate back and forth, squeezing the sludge in the sludge box 10, squeezing the sludge, and causing the sludge to accumulate at the bottom of the sludge box 10. As the sludge in the sludge box 10 increases, the pressure roller 13 is subjected to a reverse thrust from the sludge, causing the pressure roller 13 to overcome the spring telescopic rod The spring force at 17 is extended and retracted upward, and the spring telescopic rod 17 is contracted in sections, so that the pressure roller 13 maintains the pushing pressure on the sludge. The water flow in the sludge box 10 flows through the left and right openings 11 to the two water filter boxes 12 located at the left and right ends of the sludge box 10, and the residual debris and sludge in the water flow are filtered through the filter screen 18 on the water filter box 12. In the process of upward movement, the pressure roller 13 is connected between the sliding plate 15, the fixed clamping rod 22 and the lifting plate 21. The fixed clamping rod 22 moves back and forth along the lifting plate 21 during the forward and backward movement. The fixed clamping rod 22 drives the lifting plate 21 set in the clamping arrangement to move up and down during the up and down movement. The lifting plate 21 synchronously follows the pressure roller 13 to slide upward at the opening 11 to change the opening height of the opening 11.
