Description

Technical Field

[0001] This invention relates to the technical field of diversion piers, and more specifically, to a diversion pier structure suitable for lateral intake pumping stations in short diversion channels. Background Technology

[0002] In a parallel arrangement of gate pumping stations, the pumping stations are usually lateral water intake stations. Compared with lateral water intake stations, the water flow in lateral water intake stations is more prone to change direction and rotation, and the flow velocity is more likely to be unevenly distributed, resulting in undesirable flow patterns such as flow deviation and vortices.

[0003] In lateral intake pumping stations with long diversion channels, the water flow has ample time to adjust and stabilize. However, in lateral intake pumping stations with short diversion channels and large angles, the shorter channel and the larger angle between it and the station's axis make it difficult to adjust the water flow direction when entering the intake forebay. This results in unfavorable flow patterns and extremely complex flow conditions within the forebay, making the flow unstable and preventing the lateral intake pumping station from operating safely and efficiently. Summary of the Invention

[0004] The purpose of this invention is to provide a guide pier structure suitable for a short diversion channel side intake pumping station, aiming to solve the problem of unstable water flow in the intake pool in the prior art of short diversion channel side intake pumping stations.

[0005] This invention is implemented as follows: it is applicable to the guide pier structure of a lateral intake pumping station with a short diversion channel, comprising a lateral diversion channel arranged between the inlet pool and the main channel of the pumping station, wherein the main channel is connected to the inlet pool through the lateral diversion channel, and the lateral diversion channel is arranged in a curved manner; a concave water intake wall is formed on the inner side of the lateral diversion channel, a convex water intake wall is formed on the outer side of the lateral diversion channel, and a water intake bottom plate is provided at the bottom of the lateral diversion channel; The water intake base plate is provided with multiple guide piers in the middle. Along the direction from the concave water intake wall to the convex water intake wall, the multiple guide piers are arranged in sequence at intervals so that multiple guide intervals are formed in the middle of the lateral water intake channel. Along the direction from the concave water intake wall to the convex water intake wall, the multiple guide intervals are arranged in sequence at intervals. The guide pier has a water-blocking part facing the main river channel and a guide part facing the forward pool. The lateral width of the water-blocking part is greater than the lateral width of the guide part. Along the flow direction of the water in the lateral diversion channel, the guide part is connected to the front end of the water-blocking part. The water flowing from the main channel into the lateral diversion channel is blocked by the water-retaining parts of multiple guide piers, and is laterally diverted. The laterally diverted water flows pass through multiple guide intervals and are buffered and guided by multiple guide parts. The water flows after passing through multiple guide intervals are buffered and mixed.

[0006] Furthermore, along the direction from the concave side water intake wall to the convex side water intake wall, the lateral width of the flow guiding interval gradually increases.

[0007] Furthermore, the water-blocking part is arranged in a horizontal strip shape and extends along the lateral width of the lateral water diversion channel, and the flow guiding part is arranged perpendicular to the water-blocking part.

[0008] Furthermore, the rear end of the guide section is connected to the middle of the front end of the water-blocking section, and the front end of the guide section extends towards the forward water pool.

[0009] Furthermore, along the direction from the concave side water intake wall to the convex side water intake wall, the overall size of the guide pier gradually increases proportionally.

[0010] Furthermore, the rear end of the water-blocking part has a water-blocking channel that is open and facing the main river channel. The rear end of the water-blocking channel is open and facing the main river channel. The front end of the water-blocking channel forms two inclined channel walls. The inner end of the inclined channel wall extends to the middle of the water-blocking channel, and the outer end of the inclined channel wall extends to the side of the water-blocking part. Along the direction from the outside to the inside of the inclined channel wall, the inclined channel wall is inclined forward. The inclined channel wall is covered with an elastic water-retaining layer. The water flow in the main channel flows toward the water-retaining part and impacts the water-retaining layer of the water-retaining channel. The water-retaining layer elastically reflects the water flow and impacts the water flow in the main channel in the opposite direction, buffering the flow velocity of the water flow in the main channel as it enters the guide interval.

[0011] Furthermore, the middle part of the water-blocking groove is recessed forward to form a longitudinally arranged groove, and the inner end of the inclined groove wall extends to the longitudinal groove; the longitudinal groove is provided with a longitudinally arranged rotating shaft, and an elastic rotating cylinder is sleeved on the outer periphery of the rotating shaft. The rotating cylinder is arranged longitudinally, and the rotating cylinder and the rotating shaft are eccentrically arranged. The water flow entering the water-blocking trough impacts the rotating cylinder, causing the rotating cylinder to reciprocate elastically in the longitudinal trough, thus buffering the flow rate of the water in the water-blocking trough.

[0012] Furthermore, the lateral water diversion channel is provided with a fixed mesh layer, which is formed in front of multiple guide piers and is spaced apart from the multiple guide piers to form a buffer mixing zone. The rear end of the fixed mesh layer is connected to an elastic rear elastic mesh layer. The outer periphery of the rear elastic mesh layer is fixedly connected to the outer periphery of the fixed mesh layer. A rear elastic post is connected between the middle part of the rear elastic mesh layer and the fixed mesh layer, so that the middle part of the rear elastic mesh layer protrudes backward away from the fixed mesh layer. The front end of the fixed mesh layer is connected to an elastic front mesh layer. The outer periphery of the front elastic mesh layer is fixedly connected to the outer periphery of the fixed mesh layer. A front elastic post is connected between the middle part of the front elastic mesh layer and the fixed mesh layer, so that the middle part of the front elastic mesh layer protrudes forward away from the fixed mesh layer. Water flows through multiple flow guide intervals enter the buffer mixing zone for buffer mixing. After being buffered and mixed, the water flows sequentially through the rear elastic mesh layer, the fixed mesh layer, and the front elastic mesh layer for elastic buffering and rectification.

[0013] Furthermore, the two sides of the flow guide have flow guide sidewalls facing the flow guide interval, and the flow guide sidewalls are provided with a plurality of elastic plates, which are arranged sequentially and at intervals along the flow direction of the water in the flow guide interval. The outer end of the elastic sheet is abutted against the flow guide sidewall, and the inner end of the elastic sheet extends toward the flow guide interval; along the direction from the outside to the inside of the elastic sheet, the elastic sheet is inclined away from the flow direction of the water flow; an elastic band is passed through the multiple elastic sheets, and the elastic band is connected to the multiple elastic sheets respectively and extends along the flow direction of the water flow. During the flow of water in the flow guide interval, the water impacts multiple elastic plates and reciprocates elastically to buffer the flow velocity of the water in the flow guide interval; during the reciprocating elastic oscillation of the multiple elastic plates, the elastic band elastically drives the multiple elastic plates to oscillate in the same direction.

[0014] Furthermore, the water-diverting bottom plate is recessed downwards to form a bottom groove, and the bottom of the flow guide pier is provided with a protrusion facing downwards. The protrusion is movably embedded in the middle of the bottom groove. Elastic blocks are connected to both ends of the bottom groove, and the elastic blocks press against the ends of the bottom groove so that the protrusion is elastically connected in the bottom groove. During the process of water flow impacting the guide pier, the two elastic blocks reciprocate elastically deform, and the protrusion moves elastically back and forth along the bottom groove to elastically buffer the flow rate of the water flow.

[0015] Compared with the prior art, the guide pier structure provided by the present invention is suitable for the side intake pumping station of the short diversion channel. After the water flow from the main river enters the side diversion channel, it is first blocked laterally by the water-blocking parts of multiple guide piers. Since the lateral width of the water-blocking parts is greater than the lateral width of the guide parts, the water-blocking area is large. The water-blocking parts can first block and divert the water flow, effectively reducing the flow velocity of the water flow.

[0016] After the water flow slows down, it passes through multiple guide intervals, where the guide section guides the flow direction to buffer and stabilize the flow, thereby ensuring the orderliness and stability of the water flow and reducing undesirable flow patterns.

[0017] After passing through multiple guide intervals, the water flow is buffered and mixed, resulting in a uniform flow velocity distribution and a smoothed flow pattern. This ensures a stable flow pattern for the water entering the forward pool and guarantees the efficient operation of the pumping station. Attached Figure Description

[0022] Reference Figures 1-6 The image shows a preferred embodiment of the present invention.

[0023] A guide pier structure suitable for a short diversion channel lateral intake pumping station includes a lateral diversion channel 100 arranged between the inlet pool and the main channel of the pumping station. The main channel is connected to the inlet pool through the lateral diversion channel 100. The lateral diversion channel 100 is arranged in a curved manner. A concave water intake wall 101 is formed on the inner side of the lateral diversion channel 100, and a convex water intake wall 102 is formed on the outer side of the lateral diversion channel 100. The bottom of the lateral diversion channel 100 has a water intake base plate 103. Multiple guide piers 200 are provided in the middle of the water diversion base plate 103. Along the direction from the concave water diversion wall 101 to the convex water diversion wall 102, the multiple guide piers 200 are arranged in sequence at intervals so that multiple guide intervals 201 are formed in the middle of the lateral water diversion channel 100. Along the direction from the concave water diversion wall 101 to the convex water diversion wall 102, the multiple guide intervals 201 are arranged in sequence at intervals. The guide pier 200 has a water-blocking part 300 facing the main river channel and a guide part 400 facing the forward pool. The lateral width of the water-blocking part 300 is greater than the lateral width of the guide part 400. Along the flow direction of the water in the lateral diversion channel 100, the guide part 400 is connected to the front end of the water-blocking part 300. The water flow entering the lateral diversion channel 100 from the main channel is blocked by the water-blocking parts 300 of multiple guide piers 200, and is laterally diverted. The water flow after the lateral diversion passes through multiple guide intervals 201 and is buffered and guided by multiple guide parts 400. The water flow after passing through multiple guide intervals 201 is buffered and mixed.

[0024] The aforementioned guide pier structure for lateral intake pumping stations in short diversion channels, after the main river water flows into the lateral diversion channel 100, is first laterally blocked by multiple guide piers 200 and water-blocking parts 300. Since the lateral width of the water-blocking parts 300 is greater than the lateral width of the guide parts 400, the water-blocking area is large, and the water-blocking parts 300 can first block and divert the water flow, effectively reducing the flow velocity.

[0025] After the water flow slows down, it passes through multiple guide intervals 201 and is guided by the guide section 400 to buffer and guide the flow, making the flow more stable, so as to ensure the orderliness and stability of the water flow and reduce the undesirable flow state of the water flow.

[0026] After passing through multiple guide intervals 201, the water flow is buffered and mixed, resulting in a uniform flow velocity distribution and a smoothed flow pattern. This ensures a stable flow pattern for the water entering the forward pool and guarantees the efficient operation of the pump station.

[0027] As an extended embodiment, the lateral width of the flow guide interval 201 gradually increases along the direction from the concave side water guide wall 101 to the convex side water guide wall 102.

[0028] Since the lateral water diversion channel 100 is arranged in a curved manner, the water flow will be biased towards the convex water diversion wall 102 under the action of inertia, so the flow velocity at the convex water diversion wall 102 is higher than that at the concave water diversion wall 101. The wider guide interval 201 provides sufficient flow space for the high-velocity water flow at the convex side water intake wall 102, preventing the flow velocity from increasing further due to insufficient flow area. The narrower guide interval 201 matches the low-velocity water flow at the concave side water intake wall 101, so that the flow velocity distribution of the water flow is uniform.

[0029] As an extended embodiment, the water-blocking part 300 is arranged in a horizontal strip shape and extends along the lateral width of the lateral water diversion channel 100, and the flow guiding part 400 is arranged perpendicular to the water-blocking part 300.

[0030] In this way, the water-blocking part 300 can form a frontal obstruction to the incoming flow of the main river channel. The water flow is diverted from both sides of the water-blocking part 300 and then enters the diversion interval 201. The diversion part 400 guides the diverted water flow, making the flow direction of the water flow regular and reducing the intensity of turbulence.

[0031] As an extended embodiment, the rear end of the flow guide 400 is connected to the middle of the front end of the water blocking part 300, and the front end of the flow guide 400 extends toward the forward water pool.

[0032] In this way, after the water flow is diverted from both sides of the water-blocking part 300, it can flow symmetrically on the left and right sides of the guide part 400. The streamline distribution is symmetrical, which weakens the conditions for the generation of deflection flow and secondary flow.

[0033] As an extended embodiment, the overall size of the guide pier 200 gradually increases proportionally along the direction from the concave side water intake wall 101 to the convex side water intake wall 102.

[0034] Because the water flow velocity is high at the convex side water intake wall 102, the larger guide pier 200 has a stronger blocking and guiding effect on the water flow at the convex side water intake wall 102. The water flow velocity is low at the concave side water intake wall 101, and the smaller guide pier 200 can meet the guiding requirements. Thus, the guiding capacity of the guide pier 200 matches the incoming flow conditions, and the flow velocity distribution is more uniform.

[0035] As an extended embodiment, the rear end of the water-blocking part 300 has a water-blocking channel 301 that faces the main river channel and is openly arranged. The rear end of the water-blocking channel 301 is openly arranged facing the main river channel, and the front end of the water-blocking channel 301 forms two inclined channel walls 302. The inner end of the inclined channel wall 302 extends to the middle of the water-blocking channel 301, and the outer end of the inclined channel wall 302 extends to the side of the water-blocking part 300. Along the direction from the outside to the inside of the inclined channel wall 302, the inclined channel wall 302 is arranged to be inclined forward. An elastic water-retaining layer 303 covers the inclined channel wall 302. The water flow in the main channel flows toward the water-retaining part 300 and impacts the water-retaining layer 303 of the water-retaining channel 301. The water-retaining layer 303 elastically reflects the water flow and impacts the water flow in the main channel in the opposite direction, buffering the flow velocity of the water flow in the main channel into the guide interval 201.

[0036] The water flow is open to the main channel through the water-retaining channel 301. The water flow entering the water-retaining channel 301 impacts the elastic water-retaining layer 303 and is reflected. The reflected water flow and the subsequent incoming flow collide with each other in the water-retaining channel 301. In this way, the kinetic energy of the water flow is consumed twice: once by the elastic deformation of the water-retaining layer 303 and once by the mutual interference of the water flow during the collision.

[0037] The inclined channel wall 302 is inclined forward from the outside to the inside, so that after the reflected water flows out of the water-blocking channel 301, it forms a reverse push on the water flowing into the flow-guiding interval 201, thereby further reducing the flow velocity at the inlet of the flow-guiding interval 201.

[0038] As an extended embodiment, the middle part of the water-blocking groove 301 is recessed forward to form a longitudinally arranged longitudinal groove 304, and the inner end of the inclined groove wall 302 extends to the longitudinal groove 304; a longitudinally arranged rotating shaft 305 is provided in the longitudinal groove 304, and an elastic rotating cylinder 306 is sleeved on the outer periphery of the rotating shaft 305. The rotating cylinder 306 is arranged longitudinally, and the rotating cylinder 306 and the rotating shaft 305 are eccentrically arranged. The water flow entering the water-blocking groove 301 impacts the rotating cylinder 306, causing the rotating cylinder 306 to reciprocate elastically in the longitudinal groove 304, thus buffering the flow rate of the water in the water-blocking groove 301.

[0039] By eccentrically arranging the rotating cylinder 306 and the rotating shaft 305, when the water flow impacts the rotating cylinder 306, the eccentric arrangement causes the rotating cylinder 306 to deflect towards the side of the water flow direction. After deflection, the rotating cylinder 306 elastically resets and continues to be impacted by the water flow, forming a reciprocating oscillation.

[0040] In this way, the oscillation of the rotating cylinder 306 intermittently obstructs the water flow in the opposite direction. The water flow in the water-blocking channel 301 is continuously disturbed and slowed down, making it impossible to maintain a stable flow state, thereby reducing the water flow velocity in the water-blocking channel 301.

[0041] As an extended embodiment, the lateral water diversion channel 100 is provided with a fixed mesh layer 500, which is formed in front of multiple guide piers 200 and is spaced apart from the multiple guide piers 200 to form a buffer mixing zone 501. The rear end of the fixed mesh layer 500 is connected to an elastic rear elastic mesh layer 502. The outer periphery of the rear elastic mesh layer 502 is fixedly connected to the outer periphery of the fixed mesh layer 500. A rear elastic post 503 is connected between the middle part of the rear elastic mesh layer 502 and the fixed mesh layer 500, so that the middle part of the rear elastic mesh layer 502 protrudes backward away from the fixed mesh layer 500. The front end of the fixed mesh layer 500 is connected to an elastic front elastic mesh layer 504. The outer periphery of the front elastic mesh layer 504 is fixedly connected to the outer periphery of the fixed mesh layer 500. A front elastic post 505 is connected between the middle part of the front elastic mesh layer 504 and the fixed mesh layer 500, so that the middle part of the front elastic mesh layer 504 protrudes forward away from the fixed mesh layer 500. Water flows through multiple guide intervals 201 and enters the buffer mixing zone 501 for buffer mixing. After being buffered and mixed, the water flows sequentially through the rear elastic mesh layer 502, the fixed mesh layer 500, and the front elastic mesh layer 504 for elastic buffering and rectification.

[0042] In this way, when the water flow impacts the elastic mesh layer 502, the protruding middle part first contacts the water flow and retracts towards the fixed mesh layer 500. During the retraction process, the water flow is squeezed, and the squeezed water flow is squeezed out from the mesh to reduce the flow rate of the water flow.

[0043] The water flows through the rear elastic mesh layer 502, the fixed mesh layer 500, and the front elastic mesh layer 504 in sequence. The three mesh layers consume the kinetic energy of the water flow step by step. At the same time, the fixed mesh layer 500 rectifies the water flow after it has been buffered by the rear elastic mesh layer 502. The rectified water flow is then further buffered by the front elastic mesh layer 504, thereby making the flow pattern of the water stable and uniform.

[0044] As an extended embodiment, the flow guide 400 has flow guide sidewalls 401 on both sides facing the flow guide interval 201. Multiple elastic pieces 402 are provided on the flow guide sidewalls 401. Along the flow direction of the water in the flow guide interval 201, the multiple elastic pieces 402 are arranged in sequence at intervals. The outer end of the elastic sheet 402 is connected to the flow guide sidewall 401, and the inner end of the elastic sheet 402 extends toward the flow guide interval 201. Along the direction from the outside to the inside of the elastic sheet 402, the elastic sheet 402 is inclined away from the flow direction of the water flow. An elastic band 403 is passed through the multiple elastic sheets 402, and the elastic band 403 is connected to the multiple elastic sheets 402 respectively and extends along the flow direction of the water flow. As the water flows through the guide gap 201, it impacts multiple elastic plates 402, which reciprocate elastically to buffer the flow velocity of the water in the guide gap 201. During the reciprocating elastic oscillation of the multiple elastic plates 402, the elastic band 403 elastically drives the multiple elastic plates 402 to oscillate in the same direction. In this way, the oscillation of the elastic plates 402 is synchronized, avoiding random oscillation between multiple elastic plates 402 that would cause disorderly disturbance to the water flow.

[0045] As an extended embodiment, the water-diverting bottom plate 103 is recessed downward to form a bottom groove, and the bottom of the flow guide pier 200 is provided with a protrusion 202 facing downward. The protrusion 202 is movably embedded in the middle of the bottom groove. The two ends of the bottom groove are respectively connected to elastic blocks 104, and the elastic blocks 104 press against the ends of the bottom groove so that the protrusion 202 is elastically connected in the bottom groove. During the process of water flow impacting the guide pier 200, the two elastic blocks 104 reciprocate elastically deform, and the protrusion 202 moves elastically back and forth along the bottom groove to elastically buffer the flow rate of the water flow.

[0046] When the water flow impacts the guide pier 200, the guide pier 200 moves backward along the bottom groove. During the backward movement, the elastic block 104 is compressed, and the impact energy of the water flow is absorbed by the compression deformation of the elastic block 104.

[0047] When the elastic block 104 is compressed and then recovers, it pushes the guide pier 200 back to its original position. In this way, the reciprocating movement of the guide pier 200 forms an intermittent flexible obstruction to the water flow, thereby reducing the flow velocity of the water.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The guide pier structure for a side intake pumping station of a short diversion channel as described in any one of claims 1-5, characterized in that, The flow guide section has flow guide sidewalls on both sides facing the flow guide interval. Multiple elastic plates are provided on the flow guide sidewalls. Along the flow direction of the water in the flow guide interval, the multiple elastic plates are arranged in sequence at intervals. The outer end of the elastic sheet is abutted against the flow guide sidewall, and the inner end of the elastic sheet extends toward the flow guide interval; along the direction from the outside to the inside of the elastic sheet, the elastic sheet is inclined away from the flow direction of the water flow; an elastic band is passed through the multiple elastic sheets, and the elastic band is connected to the multiple elastic sheets respectively and extends along the flow direction of the water flow. During the flow of water in the flow guide interval, the water impacts multiple elastic plates and reciprocates elastically to buffer the flow velocity of the water in the flow guide interval; during the reciprocating elastic oscillation of the multiple elastic plates, the elastic band elastically drives the multiple elastic plates to oscillate in the same direction.

10. The guide pier structure for a side intake pumping station of a short diversion channel as described in any one of claims 1-5, characterized in that, The water-diverting bottom plate is recessed downwards to form a bottom groove, and the bottom of the flow guide pier is provided with a protrusion facing downwards. The protrusion is movably embedded in the middle of the bottom groove. The two ends of the bottom groove are respectively connected to elastic blocks, which press against the ends of the bottom groove so that the protrusion is elastically connected in the bottom groove. During the process of water flow impacting the guide pier, the two elastic blocks reciprocate elastically deform, and the protrusion moves elastically back and forth along the bottom groove to elastically buffer the flow rate of the water.
