Description

Technical Field

[0001] The invention relates to the technical field of quicksand collection in a pump station, and in particular to a quicksand collection device based on water-sand two-phase flow values ​​in a forebay of a lateral pump station. Background Art

[0002] The construction technology of the side water inlet forebay is more complicated than that of the front forebay. However, due to the special construction terrain and other objective factors in some pump station areas, when the front water inlet forebay is difficult to arrange, a side water inlet forebay with a relatively small area is selected. Since the incoming water direction and the inlet direction of the side water inlet forebay are orthogonal or oblique, the deviation of the water flow direction causes the water flow to rotate in a curve. The uneven flow distribution will inevitably generate centrifugal force. Under the influence of centrifugal force, the mainstream will be backwashed, making the flow state of the side water inlet forebay poor, with a large number of vortices and backflow areas. The poor flow state of the forebay then affects the water inlet pool;

[0003] However, most of the existing lateral front pools lack dredging devices, which leads to blockage when water flow or quicksand vortex is generated. At this time, the water flow speed will be reduced, resulting in further congestion and reducing the water flow relay speed of the lateral front pool. In order to avoid the above technical problems, it is necessary to provide a quicksand collection device based on the water-sand two-phase flow values ​​of the lateral pump station front pool to overcome the above defects in the prior art.

[0043] The working principle and use process of the present invention are as follows: First, when the lateral water pipe 201 transports sand and water to the inner position of the water inlet front tank 1, the sand and water will rush from the lateral water pipe 201 to the inner wall of the water inlet front tank 1. At this time, two water flows will be formed on the inner side of the water inlet front tank 1, one of which will flow to the position of the water flow trough 219, and the other will impact the inner wall of the water inlet front tank 1 to form a backflow, and then vortices will be formed on the edge of the inner wall of the water inlet front tank 1, and these vortices will hinder the sand and water from flowing. The flow of the water causes some quicksand to flow slowly inside the water inlet fore pool 1, causing quicksand to accumulate inside the water inlet fore pool 1. At this time, the mobile motor 208 inside the control motor seat 207 is started, and then the mobile motor 208 drives the moving threaded rod 209 inside the bearing 206 to rotate. Then, the rotation of the moving threaded rod 209 drives the sliding block 204 to slide outside the sliding rod 203, thereby moving the sliding block 204 to the position where a vortex is formed inside the water inlet fore pool 1.

[0044] Next, the operator starts the high-pressure water pump 210, and the high-pressure water pump 210 will introduce water flow into the inner side of the high-pressure water pump 210 through the water inlet pipe 218, and then transport the water flow to the inner side of the water outlet pipe 211 through the high-pressure water pump 210, and then the water flow will enter the inside of the flushing pipe 215 from the water outlet pipe 211, and then enter the inside of the flushing arc plate 216 from the flushing pipe 215, and then rush to the quicksand accumulation or vortex position inside the water inlet forepool 1 through the flushing holes 217 on the outside of the flushing arc plate 216, and then the water flow will disperse the accumulated quicksand, thereby helping to dredge the inside of the water inlet forepool 1;

[0045] Then, the flushing pipe 215 is moved to the position where the vortex is formed or the position where the quicksand is accumulated by the sliding block 204. The vortex can be destroyed by the high-pressure water flow, so that the sand and water will flow to the position of the water trough 219, and the high-pressure water flow will also disperse the accumulated sand pile to prevent accumulation, thereby preventing further congestion. Then, these mixed water flows will flow to the position of the water trough 219 at the same time, and the connection rod 212, the fixed pipe 213 and the support arm 214 can ensure the stability of the flushing pipe 215 and the flushing arc plate 216 when moving in the quicksand, preventing the sand pile from breaking the flushing pipe 215 when moving the flushing pipe 215, and further ensuring the service life of the dredging device;

[0046] Then the dredged water will flow to the position of the water trough 219. At this time, the dense water will flow from the water trough 219 to the top position of the inner side of the sand collecting pool 301, and the sand with larger mass will flow from the quicksand trough 220 to the bottom position of the sand collecting pool 301 and accumulate at the bottom of the sand collecting pool 301. Then the operator can pump out the water with less sand or even no sand from the top of the sand collecting pool 301, and then the sand will settle at the bottom of the sand collecting pool 301 at the bottom position of the split filter 314. The sand will be removed every once in a while. After the water and sand are separated, when the water inlet forepool 1 needs to be dredged, the lifting rod 305 can be driven to rise and fall on the inner side of the sand collecting pool 301 by lifting and lowering the hydraulic push rod 304 inside the mounting seat 303, and the return pipe 309 can be driven to move from the top to the bottom on the inner side of the sand collecting pool 301, and the diverted water can be pumped back to the inner side of the water inlet pipe 218 through the recovery box 310 and the bottom return hole 311, and then the high-pressure water pump 210 is used to dredge the inside of the water inlet forepool 1, and the water is recycled to improve the water use efficiency;

[0047] And after using it for a period of time, the return pipe 309 can be fully lifted, so that the return pipe 309 can be fully lifted to the top position, and then the magnetic suction groove plate 312 can be pulled out from the bottom of the recovery box 310, and then the magnetic suction groove plate 312 and the filter net 313 can be cleaned and replaced to ensure the filtering efficiency.

[0048] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
