Description

Technical Field

[0001] The utility model belongs to the technical field of design of supporting facilities for water conservancy steel dam gates, in particular to a water conservancy steel dam gate with a sand clearing structure. Background Art

[0002] Steel dam gates usually refer to dams and gates built with steel, which are used to control water flow, adjust water levels and prevent floods. This type of water conservancy project plays an important role in water resource management and flood prevention. Steel dam gates usually adopt steel structures, which are corrosion-resistant, wear-resistant and highly reliable, and are suitable for various hydrological conditions and engineering needs.

[0003] Driven by the water flow, sediment gradually accumulates at the bottom of the steel dam gate. When there is too much sediment, it is easy to exert excessive force on the steel dam gate, affecting the stability of the steel dam gate. Therefore, it is necessary to clean the sand at the bottom of the dam. The existing sand cleaning device is easy to push sand out of the sand cleaning area during the reciprocating movement, affecting the sand cleaning effect. At the same time, the cost is relatively high, so a simple and effective sand cleaning device is needed. Utility Model Content

[0004] The utility model aims to provide a hydraulic steel dam gate with a sand clearing structure to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A hydraulic steel dam gate with a sand clearing structure comprises a main body device, a guiding device is arranged at the bottom of the main body device; the guiding device comprises two brackets arranged symmetrically on the left and right, a winding shaft is rotatably arranged on the top of the bracket, a second motor is installed at the front end of the winding shaft, a traction line is arranged on the winding shaft, a moving platform is arranged at the end of the traction line, two sand guide plates are rotatably arranged at the bottom of the moving platform, a first stopper is arranged on one side of the sand guide plate, and a second stopper is arranged on the side of the sand guide plate away from the first stopper.

[0007] Furthermore: the main device includes a sand discharge channel, a dam body is arranged behind the sand discharge channel, two guide rails are symmetrically arranged on the top of the sand discharge channel, a spiral rotating rod is rotatably arranged on one side of the sand discharge channel, a first motor is installed at the front end of the spiral rotating rod, and a sand discharge pipe is arranged behind the spiral rotating rod.

[0008] Furthermore: the winding shaft is connected to the bracket bearing, and the second motor is connected to the bracket bolts.

[0009] Furthermore: the traction line is wound around the winding shaft.

[0010] Furthermore: the moving platform is slidably connected to the guide rail, and the cross-section of the guide rail is circular.

[0011] Furthermore: the cross section of the first stopper is square, and the cross section of the second stopper is triangular.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the mobile platform moves from right to left, the sand guide plate remains in a closed state under the restriction of the first stopper. The two sand guide plates are regarded as a straight plate and move along the bottom of the sand discharge channel, pushing the sediment in the sand discharge channel from right to left. At the same time, the sand discharge channel supports the first motor to drive the spiral rotating rod to rotate, and the sediment pushed by the sand guide plate is discharged along the sand discharge pipe to realize the sand cleaning process. After the mobile platform moves to the leftmost end, the second motor reverses and drives the mobile platform to move to the right. At this time, the first stopper no longer blocks the sand guide plate. The sand guide plate rotates outward under the push of the sand that has just slid into the sand discharge channel until it is blocked by the second stopper. , when the mobile platform moves from left to right, the sand guide plate no longer fully pushes the sand until the mobile platform moves to the far right and then turns back, repeating the above process. The second stopper prevents the sand guide plate from being in a completely open state, preventing the sand guide plate from being unable to close with the help of the resistance of the sand when moving from right to left. By setting the design of the sand guide plate cooperating with the first stopper and the second stopper, the reciprocating mobile platform continuously transports the sand to the position of the spiral rotating rod, and at the same time, the sand will not accumulate on the right side of the sand discharge channel, so that efficient sand discharge is achieved without transferring the sand to other positions, thereby improving the sand clearing effect of the device;

[0014] 2. The design of driving the mobile platform through a traction line reduces the problem of high cost of long-distance transmission. At the same time, the device has a simple structure and a low probability of failure. BRIEF DESCRIPTION OF THE DRAWINGS

The sand discharge channel 101 is installed at the bottom of the dam body 102. Driven by the water flow, the bottom of the dam body 102 gradually accumulates sediment. The sand discharge channel 101 supports the first motor 105 to drive the spiral rotating rod 104 to rotate, and the sediment pushed by the sand guide plate 206 is discharged along the sand discharge pipe 106, so as to realize the sand cleaning process;

The two brackets 201 regularly support the second motor 203 to drive the two winding shafts 202 to rotate in different directions, driving the traction line 204 on one side to be released from the winding shaft 202, while the traction line 204 on the other side is wound onto the winding shaft 202. This process drives the middle moving platform 205 to move left and right along the guide rail 103. When the moving platform 205 moves from right to left, the sand guide plate 206 is kept in a closed state under the restriction of the first stopper 207. The two sand guide plates 206 are regarded as a straight plate and move along the bottom of the sand discharge channel 101, pushing the sediment in the sand discharge channel 101 from right to left.
