Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy project planning, and specifically relates to a diversion device for water conservancy project planning. Background Art

[0002] Water conservancy projects are the general term for various engineering constructions built to control, utilize, and protect surface and underground water resources and the environment. Water conservancy project planning is an integral part of basin planning or regional water conservancy planning. The construction of a water conservancy project will have a great impact on the surrounding environment. Therefore, when formulating a water conservancy project planning, it is necessary to start from the overall situation of the basin. When planning a water conservancy project, it is often necessary to divert the existing water flow.

[0003] A Chinese patent with the publication number CN214832344U discloses a small-section river water diversion device for water conservancy construction, including a water retaining block, a rotating cylinder, and a support rod; a gravity block is provided on the lower side of the front end of the water retaining block, a fixing block is provided at the rear end of the water retaining block, and a fixing shaft is provided at the top of the fixing block; a fixing sliding hole is provided at the top of the rotating cylinder; the support rod is slidably clamped inside the rotating cylinder, and the lower end of the support rod is a conical structure; through the setting that the sliding amplitude of the fixing shaft in the fixing sliding hole is twice the height of the fixing tooth, when the fixing shaft is located at the top of the fixing sliding hole, the fixing tooth is disengaged from the rotating tooth. At this time, the inclination angle of the rotating cylinder can be adjusted according to the terrain of the river bottom, and then the support rod is inserted into the rotating cylinder. The support rod gives the rotating cylinder an upward supporting force. At this time, the fixing shaft is located at the bottom end of the fixing sliding hole, and the fixing tooth is in contact with the rotating tooth, realizing the fixation of the water retaining block.

[0004] In the current prior art, although the river water can be diverted, the river water cannot be filtered.

In severe cases, the river water may overflow, resulting in the abnormal use of the diversion device.

[0037] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0038] As Figures 1 to 7 shown, a diversion device for water conservancy project planning according to an embodiment of the present invention includes: a mounting base 1; two trapezoidal blocks 2 symmetrically and slidably connected to both ends of the mounting base 1; an adjusting mechanism provided inside the mounting base 1 for adjusting the width between the two trapezoidal blocks 2; a diversion pipe 21 connected and fixed to the bottom end of the mounting base 1; a filter plate 26 fixed to one end of the diversion pipe 21; a filter basket 28 provided outside the filter plate 26; a cleaning mechanism provided outside the filter basket 28; the cleaning mechanism includes two connecting plates 285 fixed to the outer wall of the mounting base 1, a reciprocating screw rod 283 is rotatably connected between the two connecting plates 285 through a bearing, a moving plate 282 is threadedly connected to the reciprocating screw rod 283, a rake rod 281 is fixed to the bottom of the moving plate 282, and one side wall of the rake rod 281 is in contact with the outer wall of the filter basket 28; two guide rods 284 are fixed between the two connecting plates 285, and the moving plate 282 is slidably connected to the two guide rods 284; a second motor 286 is fixed to one side wall of the connecting plate 285, and the output shaft of the second motor 286 is fixed to one end of the reciprocating screw rod 283; a water level sensor 25 is provided above the filter basket 28, and the water level sensor 25 is installed on the mounting base 1; a rotating rod 261, an impeller 263 and a speed sensor 267 are provided on one side of the filter plate 26, the speed sensor 267 is connected to the rotating rod 261 through an auxiliary mechanism, and the speed sensor 267 is electrically connected to the second motor 286.

[0039] When planning a water conservancy project, it is often necessary to divert the existing water flow. In the existing technology, although the river water can be diverted, the function of filtering the river water cannot be achieved. The domestic garbage and grass branches mixed in the river water will enter the inside of the drain pipe, which is likely to cause blockage of the drain pipe, thereby affecting the speed of guiding the water source. In severe cases, the river water may overflow, resulting in the abnormal use of the diversion device. When the cleaning mechanism provided by the present invention is in use, a filter basket 28 is provided to filter large particle impurities such as domestic garbage and wooden branches mixed in the river water, and a filter plate 26 is used to filter the silt or other small particle impurities in the river water. A water pump is provided on the outer side of the diversion pipe 21, and the river water on one side of the mounting seat 1 is pumped to a designated position by the water pump. During the pumping process, under the action of the water flow, the impeller 263 rotates, and the rotating rod 261 is driven to rotate by the impeller 263. The rotating rod 261 drives the speed sensor 267 to rotate through the auxiliary mechanism. After a period of time, the large particle impurities cover the filter basket 28, and the water flow is slow. When the rotation speed of the speed sensor 267 is lower than the set threshold, the speed sensor 267 transmits a signal to the system, and the system controls the second motor 286 to start. The output shaft of the second motor 286 drives the reciprocating screw rod 283 to rotate, the reciprocating screw rod 283 drives the moving plate 282 to reciprocate, the reciprocating screw rod 283 drives the rake rod 281 to reciprocate, and the large particle impurities are pushed to one side by the rake rod 281, realizing the function of cleaning the impurities on the surface of the filter basket 28, so as to facilitate the diversion of the river water. During the movement of the moving plate 282, the moving plate 282 slides on the guide rod 284, and the guide rod 284 limits the movement of the moving plate 282 in the horizontal direction. A water level sensor 25 is provided on one side of the mounting seat 1. When the water level of the water level sensor 25 reaches the highest threshold, the water pump will be automatically started to divert the river water on this side to prevent a large amount of water from damaging the diversion device.

[0040] As Figure 4 and Figure 6 As shown in the figure, a rotating rod 261 is rotatably connected to the filter plate 26 through a bearing. One end of the rotating rod 261 is fixedly connected with a scraping rod 262, and the scraping rod 262 is in contact with the surface of the filter plate 26. The other end of the rotating rod 261 is arranged inside the diversion pipe 21, and two impellers 263 are installed.

[0041] The scraping rod 262 provided by the present invention is used to clean the impurities on the surface of the filter plate 26 during use. Under the action of the water pump, the river water is transported to a designated position through the diversion pipe 21. During the transportation process of the river water, under the action of the water flow, the impeller 263 is driven to rotate, the rotating rod 261 is driven to rotate by the impeller 263, the scraping rod 262 is driven to rotate by the rotating rod 261, and the small particle impurities on the surface of the filter plate 26 are scraped off by the scraping rod 262, preventing the small particle impurities from accumulating on the filter plate 26 and easily blocking the filter holes of the filter plate 26 due to accumulation.

[0042] As Figure 6 shown, the auxiliary mechanism includes a first runner 264 fixedly connected to the rotating rod 261; a cavity 229 is formed in the mounting base 1, and a second runner 266 is rotatably connected to the inner wall of the cavity 229 through a pin shaft. A belt 265 is sleeved between the second runner 266 and the first runner 264; the speed sensor 267 is fixedly connected to one end of the pin shaft.

[0043] The auxiliary mechanism provided by the present invention is used to monitor the rotation speed of the rotating rod 261 during use. During the rotation of the rotating rod 261, the first runner 264 is driven to rotate by the rotating rod 261, the belt 265 is driven to rotate by the first runner 264, the second runner 266 is driven to rotate by the belt 265, and the pin shaft and the speed sensor 267 are driven to rotate by the second runner 266, so that the rotation speed of the rotating rod 261 is monitored in real time by the speed sensor 267.

[0044] As Figure 4 and Figure 6 shown, two cross bars 27 are fixedly connected to the bottom inner wall of the cavity 229. A sliding plate 271 is slidably connected to the two cross bars 27. A first motor 273 is fixedly connected to one side wall of the sliding plate 271. The output shaft of the second motor 286 is fixedly connected to a second connecting block 274. One end of the pin shaft is fixedly connected to a first connecting block 268; the first connecting block 268 cooperates with the second connecting block 274; a photoelectric sensor 275 is installed on the outer shell of the first motor 273, and a light emitting strip is provided on the first connecting block 268. The photoelectric sensor 275 cooperates with the light emitting strip; an electric push rod 272 is fixedly connected to the inner wall of the cavity 229, and the output end of the electric push rod 272 is fixedly connected to the sliding plate 271. The photoelectric sensor 275 is electrically connected to the electric push rod 272.

[0045] When the first connecting block 268 and the second connecting block 274 provided by the present invention are in use, when the speed sensor 267 monitors that the speed of the rotating rod 261 is lower than the set threshold, it may be that large particles have blocked the filter basket 28. If the speed has not been increased after cleaning by the cleaning mechanism, it may be that the scraping rod 262 is blocked by silt. At this time, an external force needs to be provided for the rotating rod 261. The electric push rod 272 is controlled to be turned on by the photoelectric sensor 275. The electric push rod 272 pushes the sliding plate 271, the first motor 273 and the second connecting block 274 through its output end. Under the cooperation of the photoelectric sensor 275 and the light-emitting strip, the second connecting block 274 just inserts into the first connecting block 268. At the same time, the first motor 273 is turned on. The output shaft of the first motor 273 drives the second connecting block 274, the first connecting block 268 and the pin shaft to rotate. The second runner 266, the belt 265 and the first runner 264 are driven to rotate through the pin shaft. The rotating rod 261 and the scraping rod 262 are driven to rotate through the first runner 264 until the silt is dispersed, improving the applicability of the device.

[0046] As Figure 3 and Figure 5 As shown, the adjusting mechanism includes a rotating rod 221 rotatably connected to the mounting seat 1 through a bearing. One end of the rotating rod 221 extends above the mounting seat 1 and is fixedly connected with a handle 22. The other end of the rotating rod 221 is fixedly connected with a first bevel gear 223. The rotating rod 221 is connected to the inner wall of the cavity 229 through a first fixing plate 222. Two second fixing plates 224 are fixedly connected to the inner wall of the cavity 229. A bidirectional ball screw 226 is rotatably connected to the two second fixing plates 224 through bearings. A second bevel gear 225 is fixedly connected to the middle of the bidirectional ball screw 226. The second bevel gear 225 meshes with the first bevel gear 223. The trapezoidal blocks 2 are symmetrically threadedly connected to both ends of the bidirectional ball screw 226.

[0047] The adjusting mechanism provided by the present invention is used to adjust the width between the two trapezoidal blocks 2 during use, suitable for rivers of different widths. By fixing the mounting seat 1 at a set position in the river and then rotating the handle 22, the rotating rod 221 is driven to rotate under the action of the handle 22. The first bevel gear 223 is driven to rotate through the rotating rod 221. The second bevel gear 225 is driven to rotate through the first bevel gear 223. The bidirectional ball screw 226 is driven to rotate through the second bevel gear 225. The trapezoidal blocks 2 are driven to move towards both sides through the bidirectional ball screw 226 until they are in close contact with the inclined surfaces on both sides of the river, and then stop rotating, realizing the function of intercepting rivers of different widths.

[0048] As Figure 3 and Figure 5As shown, chutes 228 are respectively formed at the top and bottom of both ends of the fixed seat 23. Both ends of the trapezoidal block 2 are fixedly connected with sliders 227, and the sliders 227 are respectively slidably connected in the chutes 228.

[0049] When the sliders 227 and the chutes 228 provided by the present invention are in use, during the movement of the trapezoidal block 2, both the top and bottom of the trapezoidal block 2 slide in the chutes 228 through the sliders 227, and the sliders 227 limit the trapezoidal block 2 to move in the horizontal direction.

[0050] As Figure 1 shown, side rods 11 are fixedly connected to both ends of the top of the mounting seat 1, and the side rods 11 are respectively inserted into the ground through fixing rods 12.

[0051] When the side rods 11 and the fixing rods 12 provided by the present invention are in use, they are used to fix the top of the mounting seat 1. The top of the mounting seat 1 is fixed to the ground through the fixing rods 12, preventing the fixed seat 23 from tilting under the impact of water flow and being unable to intercept.

[0052] As Figure 1 shown, two fixed seats 23 are fixedly connected to the side wall of the mounting seat 1 away from the guide pipe 21, and the fixed seats 23 are respectively inserted into the underwater ground through anchor rods 24.

[0053] When the anchor rods 24 and the fixed seats 23 provided by the present invention are in use, they are used to stabilize the bottom of the fixed seat 23. The soil at the bottom of the river is soft, and directly inserting the bottom of the fixed seat 23 into the soil at the bottom of the river has a poor fixing effect. The bottom of the fixed seat 23 is fixed through the anchor rods 24 to improve the stability of the fixed seat 23.

[0054] Working principle: A filter basket 28 is provided to filter large particle impurities such as domestic garbage and wooden branches mixed in river water, and a filter plate 26 is used to filter silt or other small particle impurities in the river water. A water pump is provided on the outer side of the diversion pipe 21. The water pump pumps the river water on one side of the mounting seat 1 to a designated position. During the pumping process, under the action of the water flow, the impeller 263 rotates. The impeller 263 drives the rotating rod 261 to rotate, and the rotating rod 261 drives the speed sensor 267 to rotate through the auxiliary mechanism. After a period of time, the large particle impurities cover the filter basket 28, and the water flow is slow. When the rotation speed of the speed sensor 267 is lower than the set threshold value, the speed sensor 267 transmits a signal to the system, and the system controls the second motor 286 to start. The output shaft of the second motor 286 drives the reciprocating lead screw 283 to rotate, the reciprocating lead screw 283 drives the moving plate 282 to reciprocate, the reciprocating lead screw 283 drives the rake rod 281 to reciprocate, and the rake rod 281 pushes the large particle impurities to one side, realizing the function of cleaning the impurities on the surface of the filter basket 28, so as to facilitate the diversion of river water; during the movement of the moving plate 282, the moving plate 282 slides on the guide rod 284, and the guide rod 284 limits the moving plate 282 to move in the horizontal direction; a water level sensor 25 is provided on one side of the mounting seat 1. When the water level of the water level sensor 25 reaches the highest threshold value, the water pump will be automatically started to divert the river water on this side to prevent excessive water volume from damaging the diversion device;

[0055] Under the action of the water pump, the river water is transported to the designated position through the diversion pipe 21. During the transportation process of the river water, under the action of the water flow, the impeller 263 is driven to rotate. The rotating rod 261 is driven to rotate through the impeller 263, the scraping rod 262 is driven to rotate through the rotating rod 261, and the small particle impurities on the surface of the filter plate 26 are scraped off by the scraping rod 262, preventing the small particle impurities from accumulating on the filter plate 26. If the accumulation is large, it is easy to block the filter holes of the filter plate 26; during the rotation of the rotating rod 261, the first runner 264 is driven to rotate through the rotating rod 261, the belt 265 is driven to rotate through the first runner 264, the second runner 266 is driven to rotate through the belt 265, and the pin shaft and the speed sensor 267 are driven to rotate through the second runner 266, so as to monitor the rotation speed of the rotating rod 261 in real time through the speed sensor 267; when the speed sensor 267 monitors that the speed of the rotating rod 261 is lower than the set threshold, it may be that large particles block the filter basket 28. If the speed is not increased after cleaning by the cleaning mechanism, it may be that the scraping rod 262 is blocked by silt. At this time, an external force needs to be provided for the rotating rod 261; the electric push rod 272 is controlled to be opened through the photoelectric sensor 275. The electric push rod 272 pushes the slide plate 271, the first motor 273 and the second connecting block 274 through the output end. Under the cooperation of the photoelectric sensor 275 and the light-emitting strip, the second connecting block 274 just inserts into the first connecting block 268. At the same time, the first motor 273 is turned on. The output shaft of the first motor 273 drives the second connecting block 274, the first connecting block 268 and the pin shaft to rotate. The second runner 266, the belt 265 and the first runner 264 are driven to rotate through the pin shaft, and the rotating rod 261 and the scraping rod 262 are driven to rotate through the first runner 264 until the silt is dispersed, improving the applicability of the device;

[0056] By fixing the mounting seat 1 at the set position and then rotating the handle 22, the rotating rod 221 is driven to rotate under the action of the handle 22. The first bevel gear 223 is driven to rotate through the rotating rod 221, the second bevel gear 225 is driven to rotate through the first bevel gear 223, the bidirectional ball screw 226 is driven to rotate through the second bevel gear 225, and the trapezoidal block 2 is driven to move to both sides through the bidirectional ball screw 226 until it is in close contact with the inclined surfaces on both sides of the river, and then the rotation is stopped, realizing the function of intercepting river water with different widths.
