Description

Technical Field

[0001] The invention belongs to the technical field of dam pollution-blocking equipment, and in particular relates to a reservoir dam pollution-blocking device. Background Art

[0002] Reservoirs and dams are important engineering facilities for humans to transform and utilize water resources. They play a key role in flood control, irrigation, water supply, power generation, shipping and other fields. They are hydraulic projects that form reservoirs by intercepting rivers, streams or other water bodies and use water-retaining structures (dams) to control water flows. They can alleviate seasonal and regional uneven precipitation problems, ensure water supply safety, reduce peak flows by storing water, reduce downstream flood risks, and use water level differences to drive hydro-turbine generators to generate electricity (such as hydropower stations), providing water for farmland irrigation, industrial production and urban life. When the reservoir has a large inflow of water during the flood season, the scum in the reservoir area will gather near the water intake under the drive of the water flow. Therefore, corresponding mesh pollution-blocking devices such as fences are needed to be set between the reservoir dam and the water intake to block the scum.

[0003] When the existing reservoir dam trash interception device is in use, when the reservoir has a large amount of water inflow during the flood season, the flow rate and impact force are often large. At this time, large solids and scum in the water will have a large impact on the trash rack, which may cause damage to the trash rack after long-term use. When a traditional trash rack is damaged, manual inspection is required to discover it and dispatch ships and machinery for repair, which takes several hours to several days. During this period, floating objects may block the water intake or affect the safety of the dam body, which will cause certain defects in the use of the dam trash interception device.

[0004] Therefore, we propose a reservoir dam pollution-blocking device to solve the above-mentioned problems. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention can eventually unfold the water-filled curtain and the fence net through the cooperation between the various parts of the linkage mechanism, so that the unfolded fence net covers the damaged interception fence surface, realizes automatic repair of the damaged interception fence surface, completes rapid emergency interception, avoids the expansion of accidents, and can convert damage events into temporary emergency coverage. While ensuring the normal use and interception of the sewage interception device, it is also convenient for staff to maintain the damaged part of the interception fence. At the same time, the water-filled curtain and the fence net are separately set corresponding to the main interception nets of multiple unit settings, thereby performing modular settings, so that specific damaged areas of the interception fence can be repaired separately, which is beneficial to reducing the redundancy of large-scale repairs and ensuring that other areas can be repaired separately when damaged. At the same time, the water-filled curtain's water supply relies on the natural conversion of water flow by the rotating impeller, which is beneficial to reducing external power supply equipment and reducing the consumption of external energy.

[0019] 2. The present invention cooperates with various parts of the connecting mechanism and the air distribution mechanism. When the first air outlet discharges air toward the surface of the intercepting fence, the airflow can flush the surface of the intercepting fence to a certain extent, causing the water flow to be disturbed, and can flush the pollutants attached to the intercepting fence in real time, reducing the possibility of blockage of the intercepting fence. When the second air outlet discharges air upward, the floating bubbles can be used to lift the scum and the like upward, thereby leaving the surface of the intercepting fence to avoid the accumulation and squeezing of pollutants and impurities in the water on the surface of the intercepting fence, thereby helping to reduce the possibility of damage to the intercepting fence, and making the impurities and scum float up, which is beneficial to the subsequent processing and salvage of the impurities. At the same time, the continuously blown airflow relies on the natural conversion of the water flow by the rotating impeller, which is beneficial to further reduce the consumption of external energy supply equipment and improve the use effect of the device.

[0020] 3. The present invention can continuously push the scum accumulated on the water surface in front of the device toward the shore through the cooperation between the various parts of the material-dispensing mechanism, so that the salvage personnel only need to use a net bag or a small grab bucket on the shore to carry out the salvage operation, without having to go into the water, thereby improving the safety of the device during use. Continuously pushing the scum toward the shore is also conducive to reducing the squeezing impact of the scum on the device, thereby further reducing the possibility of damage to the device. At the same time, relying on the rotation of the rotating impeller, it is conducive to further improving the utilization of natural forces and ensuring the use effect of the device.

DETAILED DESCRIPTION

[0032] The application will be further described below in combination with specific embodiments.

[0033] To solve the problem that the traditional trash rack needs to be manually checked, found and dispatched by ships and mechanical maintenance after being damaged, which takes several hours to several days, and during which the floating objects may block the water intake or affect the safety of the dam body, thereby causing certain defects in the use of the dam trash rack, such as Figure 1 Figure 7 As shown in the figure:

[0034] A reservoir dam trash rack, comprising a main body screen 1 and a linkage mechanism 2, the main body screen 1 comprises a floating top 101, a middle part below the floating top 101 is provided with an intercepting fence 102, and both sides of the floating top 101 are provided with side support plates 103, the bottom of the intercepting fence 102 is installed with a counterweight bottom plate 104, the floating top 101 is made of high-strength polyethylene material, and the floating top 101, the intercepting fence 102 and the side support plates 103 are arranged in multiple units about the main body screen 1.

[0035] ​The linkage mechanism 2 for repairing damage is arranged at the rear of the main body of the net 1. The linkage mechanism 2 includes a support frame 201 arranged at the rear of the main body of the net 1. A first gear set 202 is provided in the middle part of the inner side of the support frame 201, and a rotating impeller 203 is installed in the middle part of the front end of the first gear set 202. The first rotating shaft 204 is connected to both sides of the first gear set 202, and a second gear set 205 is provided at the front end of the first rotating shaft 204. A second rotating shaft 206 is connected to the top of the second gear set 205, and a turntable 207 is installed on the top of the second rotating shaft 206. The gear sets are composed of two sets of meshing bevel gears arranged at ninety degrees.

[0036] The support frame 201 is fixedly connected to the side support plate 103, and the rotating impeller 203 is rotatably connected to the support frame 201 through the first gear set 202. The rotating impeller 203 is rotatably connected to the second gear set 205 through the first gear set 202 and the first rotating shaft 204, and the second gear set 205 is rotatably connected to the turntable 207 through the second rotating shaft 206. The front surface of the rotating impeller 203 is provided with an industrial vision camera based on existing principles, which is controlled by the control room of the dam.

[0037] A linkage piston 208 is rotatably connected to the upper side of the turntable 207, and a piston cylinder 209 is provided on the outer side of the front end of the linkage piston 208, a water pipe 210 is connected to the lower side of one side of the piston cylinder 209, and a water pipe 211 is connected to the front side of the piston cylinder 209, and an air pipe 212 is connected to the upper side of the other side of the piston cylinder 209, the output end of the water pipe 211 is connected to a water-filled curtain 214, and a collecting tank 213 is provided on the outside of the water-filled curtain 214, one end of the water-filled curtain 214 is connected to a flow pipe 215, and a counterweight block 216 is provided at the bottom of the water-filled curtain 214, and clamps 217 are provided on both sides of the counterweight block 216, and a fence net 218 is provided on the sides of the water-filled curtain 214 and the counterweight block 216.

[0038] The linked piston 208 is slidingly connected to the piston cylinder 209 through the turntable 207, and the piston cylinder 209 is connected to the water-filled curtain 214 and the circulation pipe 215 through the water pipe 211. The counterweight block 216 is clamped with the collection tank 213 through the clamping head 217. The water pipe 210 is perpendicular to the water, and a filter is provided at the entrance. The air pipe 212 is set on the water surface. The water pipe 210, the water pipe 211 and the air pipe 212 are connected to the piston cylinder 209 with solenoid valves, and are all controlled by the control room of the dam. The water-filled curtain 214 is folded in a Z shape in the collection tank 213, and is set on both sides of the front inner side of the floating top 101. The fence net 218 is folded in the middle of the two groups of water-filled curtains 214.

[0039] By rotating the impeller 203, when water flows to the water intake of the dam, and when the water inflow to the reservoir is large during the flood season, the impeller 203 can be driven to rotate. By using the first gear set 202, the first rotating shaft 204, and the second gear set 205, the rotating force of the rotating impeller 203 can be transmitted to the second rotating shaft 206, so that the second rotating shaft 206 drives the rotating disk 207 to rotate. A connecting rod is provided between the rotating disk 207 and the linked piston 208, and the connecting rod can be used to drive the rotating disk 207 to rotate when the rotating disk 207 rotates. The linked piston 208 moves left and right in the piston cylinder 209. When the industrial vision camera installed on the front surface of the rotating impeller 203 detects that the surface of the intercepting fence 102 is damaged, it is controlled by the existing control principle. At this time, the solenoid valves connected to the piston cylinder 209 at the air pipe 212 and the air outlet pipe are closed, and the solenoid valves connected to the piston cylinder 209 at the water pipe 210 and the water guide pipe 211 are opened, and a one-way water inlet valve is provided at the water pipe 210, and a one-way water outlet valve is provided at the water guide pipe 211.

[0040] When the piston 208 moves left and right in the piston cylinder 209, the piston cylinder 209 will use the water guide pipe 210 to continuously pump water into the water guide pipe 211. The water drawn out is continuously filled into the water-filled curtain 214 by the conduction of the water guide pipe 211. The water is continuously passed into the folded water-filled curtain 214 below by the flow pipe 215, so that the water-filled curtain 214 continues to expand and become larger. A pressure relief valve is provided on the lower side of the water-filled curtain 214, which can discharge excess water when the water filling volume reaches a certain level to prevent the water-filled curtain 214 from bursting. The continuous expansion of the water-filled curtain 214 will generate an extrusion pressure in the collecting tank 213. When the pressure reaches a certain level, the counterweight block 216 will be squeezed out by the engagement force between the clamping head 217 and the collecting tank 213. At this time, the counterweight block 216 will fall, driving the folded water-filled curtain 214 and the fence net 218 to fall together, thereby making the water-filled curtain 214 14 and the fence net 218 are unfolded, so that the unfolded fence net 218 covers the surface of the damaged interception fence 102, and the damaged surface of the interception fence 102 is automatically repaired to complete rapid emergency interception and avoid the expansion of the accident. The damage event can be converted into a temporary emergency cover, while ensuring the normal use and interception of the sewage interception device, it is also convenient for the staff to maintain the damaged part of the interception fence 102. At the same time, the water-filled curtain 214 and the fence net 218 are separately set corresponding to the main interception nets 1 of the multiple unit settings, so as to be modularly set, so that the specific damaged area of ​​the interception fence 102 can be repaired separately, which is conducive to reducing the redundancy of large-scale repairs and ensuring that other areas can be repaired separately when damaged. At the same time, the water-filled energy supply of the water-filled curtain 214 relies on the natural conversion of the water flow by the rotating impeller 203, which is conducive to reducing external energy supply equipment and reducing the consumption of external energy.

[0041] In order to solve the problem that scum in the water easily accumulates on the surface of the screen, causing the screen to be blocked and the screen to be easily damaged by the squeezing of scum, such as Figure 1 - Figure 5 as well as Figure 8 and Figure 9 As shown:

[0042] A connecting mechanism 3 is connected to the lower front side of the linkage mechanism 2, and the connecting mechanism 3 includes an air guide tube 301 connected to the front side of the piston cylinder 209, a ventilation tube 302 is connected to the lower front end of the air guide tube 301, and a first air distribution tube 303 is connected to one side of the ventilation tube 302. A plurality of first air outlets 304 are installed on the surface of the first air distribution tube 303, and an electromagnetic valve is provided at the connection between the air guide tube 301 and the piston cylinder 209.

[0043] The bottom of the connecting mechanism 3 is connected to an air distribution mechanism 4, which includes a second air distribution pipe 401 connected below the ventilation pipe 302, a second air outlet 402 is installed on the surface of the second air distribution pipe 401, and a rotating valve cover 403 is installed on the front end surface of the second air outlet 402, and a connecting spring 404 is connected to the upper and lower sides of the inner side of the rotating valve cover 403, the first air distribution pipe 303 and the first air outlet 304 are arranged on the rear surface of the intercepting fence 102, the second air distribution pipe 401 is vertically arranged on the front side of the counterweight base plate 104, and the second air outlet 402 opens upward.

[0044] The piston cylinder 209 is connected to the first air distribution pipe 303 through the air guide pipe 301, the ventilation pipe 302, and the first air distribution pipe 303, and the ventilation pipe 302 is connected to the second air outlet 402 through the second air distribution pipe 401. The rotating valve cover 403 is elastically connected to the second air outlet 402 through the connecting spring 404. Through the connecting mechanism 3 and the air distribution mechanism 4, the scum intercepted on the surface of the interception fence 102 can be lifted and the interception fence 102 can be flushed.

[0045] Through the air guide pipe 301 and the air duct 212, when the intercepting fence 102 is not damaged and is in normal use, the solenoid valve connected to the piston cylinder 209 is in the open state, and the solenoid valve connected to the water guide pipe 210 and the water guide pipe 211 and the piston cylinder 209 is in the closed state, and a one-way air inlet valve is provided at the air guide pipe 212, and a one-way air outlet valve is provided at the air guide pipe 301. At this time, when the linked piston 208 moves left and right in the piston cylinder 209, the piston cylinder 209 will use the air guide pipe 212 to continuously pump air into the air guide pipe 301, and use the ventilation pipe 302 to conduct the airflow, so that the airflow is distributed in the first air distribution pipe 303 and the second air distribution pipe 401, and finally discharged into the water from the first air outlet 304 and the second air outlet 402. By rotating the valve cover 403 and the connecting spring 404, the first air outlet 304 and the second air outlet can be ensured. The unidirectional air outlet of the air outlet 402 allows the air to be discharged from the first air outlet 304 toward the surface of the interception fence 102. The air flow can flush the surface of the interception fence 102 to a certain extent, causing the water flow to be disturbed, and can flush the pollutants attached to the interception fence 102 in real time, reducing the possibility of blockage of the interception fence 102. When the air is discharged upward from the second air outlet 402, the floating bubbles can be used to lift the scum and the like upward, thereby leaving the surface of the interception fence 102, to avoid the accumulation and squeezing of pollutants and impurities in the water on the surface of the interception fence 102, thereby helping to reduce the possibility of damage to the interception fence 102, and allowing the impurities and scum to float up, which is beneficial for the subsequent processing and salvage of the impurities. At the same time, the continuously blown air flow relies on the natural conversion of the water flow by the rotating impeller 203, which helps to further reduce the consumption of external energy supply equipment and improve the use effect of the device.

[0046] In order to solve the problem that the scum is difficult to remove due to accumulation on the water surface in front of the device, which increases the difficulty of salvage and the pressure of the device, Figure 1 - Figure 5 as well as Figure 10 As shown:

[0047] A material-dispensing mechanism 5 is provided on the front side of the upper end of the linkage mechanism 2. The material-dispensing mechanism 5 includes a third gear set 501 which is provided on the lower side of the turntable 207 and rotates synchronously with the second rotating shaft 206. One side of the third gear set 501 is connected to the first linkage shaft 502, and the other side of the first linkage shaft 502 is provided with a fourth gear set 503. A linkage gear 504 is provided at the front end of the fourth gear set 503.

[0048] The front end of the linkage gear 504 is connected to the second linkage shaft 505, and the front end of the second linkage shaft 505 is fixed with a fixed rotating cylinder 506, the outer surface of the fixed rotating cylinder 506 is fixed with a prying piece 507, and the fourth gear set 503 is provided with a third linkage shaft 508 on the side away from the first linkage shaft 502.

[0049] The second rotating shaft 206 is rotatably connected to the linkage gear 504 through the third gear set 501, the first linkage shaft 502 and the fourth gear set 503, and the linkage gear 504 is rotatably connected to the fixed rotating drum 506 and the prying piece 507 through the second linkage shaft 505. The prying mechanism 5 can automatically remove the scum.

[0050] The rotational force of the second rotating shaft 206 can be transmitted through the third gear set 501, so that the first connecting shaft 502 can drive the fourth gear set 503 and the connecting gear 504 of the meshing bevel gear to rotate, thereby causing the second connecting shaft 505 to drive the fixed rotating drum 506 and the stripping piece 507 to rotate. At the same time, multiple groups of fixed rotating drum 506 and stripping piece 507 are provided about the float top 101, which can rotate synchronously in one direction, so that the scum accumulated on the water surface in front of the device can be continuously pushed to the shore, so that the salvage personnel only need to use a net bag or a small grab bucket on the shore to carry out salvage operations, and the personnel do not need to go into the water, which improves the safety of the device during use. Continuously pushing the scum to the shore is also conducive to reducing the squeezing impact of the scum on the device, thereby further reducing the possibility of damage to the device. At the same time, the fixed rotating drum 506 and the stripping piece 507 also rely on the natural conversion of the water flow by the rotating impeller 203 to rotate, which is conducive to further improving the utilization of natural forces and improving the use effect of the device.
