Description

Technical Field

[0001] This invention relates to the field of water conservancy project maintenance and construction technology, and specifically to a construction device for water conservancy project maintenance. Background Technology

[0002] During the pruning process of water conservancy projects, it is necessary to build an upstream cofferdam, which is a small temporary dam, on the main river channel downstream of the diversion channel entrance to block the river water and divert all the river water to the diversion channel. This is called flow interception. Traditional flow interception methods often use the vertical blocking method, which involves first filling the riverbed with diversion embankments on one or both sides to gradually narrow the riverbed, a process called encroachment.

[0003] In the existing technology, when workers carry out the construction of water conservancy projects, a large amount of raw materials need to be put into the construction of water conservancy projects. At this time, it is necessary to frequently transport raw materials to both sides of the river. The existing technology cannot facilitate the workers to transport large equipment, and with the increase of the number of transports, mud and other dirt will inevitably remain on the surface of the equipment, which cannot be cleaned by the existing technology. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: a construction device for water conservancy project maintenance, comprising a water-blocking mechanism, a support mechanism fixedly connected to the outer surface of the top of the water-blocking mechanism, a support rod rotatably connected to the outer surface of the bottom of the support mechanism, and a hydraulic rod rotatably connected to the end of the support rod away from the support mechanism. The outer surface of the hydraulic rod is fixedly connected to the inner surface of the water-blocking mechanism. When the device is inserted into the river channel upstream of the water conservancy project, it prevents the flow of water in the river channel, thereby facilitating the maintenance work of the water conservancy project downstream by construction personnel. At this time, the water-blocking mechanism can block the flow of water in the river channel, and the hydraulic rod moves upward and opens the support mechanism through the support rod, which facilitates the workers to transport materials to both banks of the river.

[0005] The support mechanism includes a fixed plate, a top guard plate fixedly connected to the upper surface of the fixed plate, a spraying component fixedly connected to the inner surface of the top guard plate, a support plate at the bottom of the spraying component, a side plate slidably connected to the inner surface of the support plate, and a rotatably connected lower surface of the side plate to the top end of a support rod. The hydraulic rod moves upward and pushes the support plate to rotate along the surface of the fixed plate through the support rod. When the upper surface of the support plate contacts the lower surface of the top guard plate, the surface of the support plate is horizontal with the surface of the top guard plate, and the support plate cannot continue to flip upward.

[0006] Preferably, the outer surfaces of both sides of the fixed plate are rotatably connected to the inner surface of the support plate on the side away from the side plate. A V-shaped movable rod is rotatably connected to the inner surface of the support plate. The end of the V-shaped movable rod away from the support plate is rotatably connected to the outer surface of the side plate. The upper surface of the support plate is in contact with the lower surface of the top guard plate. As the hydraulic rod continues to move upward, the support rod can drive the side plate to slide out from inside the support plate.

[0007] Preferably, a sliding rod is rotatably connected to the outer surface of the V-shaped movable rod, and a sleeve is slidably connected to the outer surface of the sliding rod. A tension spring is provided inside the sleeve, and both ends of the tension spring are fixedly connected to the end of the sliding rod away from the V-shaped movable rod. When the side plate slides out from the support plate, the opening of the V-shaped movable rod becomes larger, the sliding rod slides outward along the inner surface of the sleeve, and the tension spring is stretched. Then, the material can be transported through the top guard plate, support plate, and side plate, thereby increasing the horizontal unfolding area of ​​the entire support mechanism.

[0008] Preferably, the spraying component includes a spraying pipe, a fixing ring is fixedly connected to the inner surface of the spraying pipe, a rectangular sleeve is slidably connected to the inner surface of the fixing ring, a push plate is fixedly connected to the outer surface of the rectangular sleeve away from the fixing ring, the outer surface of the push plate is slidably connected to the inner surface of the spraying pipe, and a rectangular nozzle is fixedly connected to the outer surface of the spraying pipe. As the incoming water flow gradually increases, the pressure inside the spraying pipe gradually increases. At this time, the rectangular sleeve moves together with the push plate, and the water flow can be sprayed out from the surface of the rectangular nozzle after passing through the water passage.

[0009] Preferably, a limiting ring is fixedly connected to the inner surface of the spray pipe, the outer surface of the limiting ring is in contact with the outer surface of the push plate, a compression spring is fixedly connected to the outer surface of the push plate, and the end of the compression spring away from the push plate is fixedly connected to the outer surface of the fixing ring. A water passage hole is opened in the wall of the rectangular sleeve, the outer surface of the spray pipe is fixedly connected to the inner surface of the top guard plate, the limiting ring restricts the movement stroke of the push plate, and the rectangular nozzle can change the position of the water flow when it is sprayed, thereby increasing the coverage area when the water flow is sprayed.

[0010] Preferably, the water-blocking mechanism includes a gate plate. The inner surface of the gate plate is fixedly connected to the lower surface of a hydraulic rod via a groove, and the groove is formed in the wall of the gate plate. A pneumatic push rod is fixedly connected to the inner surface of the top of the gate plate. A water-blocking plate is fixedly connected to the output end of the pneumatic push rod. A limit plate is slidably connected to the outer surface of the water-blocking plate. A filter screen is fixedly connected to the outer surface of the limit plate. The outer surface of the filter screen is fixedly connected to the outer surface of the gate plate. The upper surface of the gate plate is fixedly connected to the lower surface of the fixed plate. By controlling the upward movement distance of the water-blocking plate through the pneumatic push rod, the flow rate of the water in the river can be adjusted. At the same time, a portion of the water flow is transported to the support mechanism through a suction component to facilitate the rinsing of the surface of the support mechanism.

[0011] Preferably, the outer surface of the limiting plate is fixedly connected to the inner surface of the gate, the inner surface of the gate is slidably connected to the outer surface of the water-blocking plate, a clearing rod is fixedly connected to the outer surface of the water-blocking plate, the outer surface of the clearing rod is slidably connected to the inner surface of the filter screen, and a suction component is fixedly connected to the inner surface of the gate, the outer surface of the suction component is fixedly connected to the inner surface of the limiting plate. When the pneumatic push rod drives the water-blocking plate to slide upward along the inner surface of the limiting plate, water can flow through the surface of the filter screen. The clearing rod moves upward together with the water-blocking plate to prevent sludge from accumulating at the bottom of the gate and clogging the filter screen.

[0012] Preferably, the suction component includes a suction pipe, a half-shell fixedly connected to the bottom end of the suction pipe, a rotating shaft rotatably connected to the inner surface of the half-shell, a spiral blade fixedly connected to the outer surface of the rotating shaft, the outer surface of the spiral blade rotatably connected to the inner surface of the suction pipe, a baffle fan fixedly connected to the outer surface of the rotating shaft, the outer surface of the suction pipe fixedly connected to the inner surface of the gate, and the inner surface of the gate fixedly connected to the lower surface of the half-shell. When water flows through the gate, the water flow is driven to rotate in one direction by the baffle fan under the baffle effect of the half-shell. At this time, the baffle fan can drive the spiral blade to rotate through the rotating shaft, and transport part of the water flow to the support mechanism through the suction pipe.

[0013] Preferably, a filter plate is fixedly connected to the inner surface of the suction pipe, the inner surface of the filter plate is rotatably connected to the outer surface of the rotating shaft, a scraper is fixedly connected to the outer surface of the rotating shaft, the outer surface of the bottom of the scraper is rotatably connected to the upper surface of the filter plate, and the inner surface of the top of the suction pipe is fixedly connected to the inner surface of the fixed plate. The filter plate can filter the water flowing into the suction pipe to ensure that the mud and sand at the bottom of the river are not sprayed onto the surface of the support mechanism when rinsing it. At the same time, the scraper rotates with the rotating shaft to prevent the surface of the filter plate from becoming clogged.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention, by setting up a support mechanism, allows the hydraulic rod installed in the groove to move upward during use, making the surface of the support plate level with the surface of the top guard plate. Then, as the hydraulic rod continues to move upward, the support rod can drive the side plate to slide out from the support plate. Subsequently, materials can be transported through the top guard plate, support plate, and side plate, thereby increasing the horizontal unfolding area of ​​the entire support mechanism, making it convenient for workers to transport materials and large equipment to both sides of the river.

[0016] 2. This invention uses a water-blocking mechanism to obstruct the flow of water in a river channel, facilitating maintenance work on the water conservancy project downstream by construction personnel. A pneumatic push rod drives the water-blocking plate to slide upward along the inner surface of the limiting plate, allowing water to flow through the surface of the filter screen. The dredging rod moves upward along with the water-blocking plate to prevent silt from accumulating at the bottom of the gate and clogging the filter screen. The flow rate of the water in the river channel can be adjusted by controlling the upward movement distance of the water-blocking plate with the pneumatic push rod.

[0017] 3. By setting up a suction component, when water flows through the gate, the turbulence fan drives the spiral blades to rotate through the rotating shaft, and delivers part of the water flow to the support mechanism through the suction pipe, so as to wash the surface of the support mechanism. During this process, the filter plate can filter the water flow entering the suction pipe to ensure that the mud and sand at the bottom of the river are not sprayed onto the surface of the support mechanism when washing the support mechanism. At the same time, the scraper rotates with the rotating shaft to prevent the surface of the filter plate from being blocked.

[0018] 4. By setting up a spraying component, as the incoming water flow gradually increases, the pressure inside the spraying pipe gradually increases. At this time, the rectangular sleeve moves together with the push plate, and the water flow can be sprayed out from the surface of the rectangular nozzle after passing through the water passage. The rectangular nozzle can change the position of the water flow when it is sprayed out, increasing the coverage area of ​​the water flow when it is sprayed out. This allows the surface of the support plate and side plate to be rinsed, preventing silt from remaining on the surface of the support plate and side plate when workers transport materials.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] Example: Please refer to Figure 1 - Figure 8 This invention provides a technical solution: a construction device for water conservancy project maintenance, including a water-blocking mechanism 1, a support mechanism 2 fixedly connected to the outer surface of the top of the water-blocking mechanism 1, a support rod 4 rotatably connected to the outer surface of the bottom of the support mechanism 2, and a hydraulic rod 3 rotatably connected to the end of the support rod 4 away from the support mechanism 2. The outer surface of the hydraulic rod 3 is fixedly connected to the inner surface of the water-blocking mechanism 1. The device is inserted into the river channel upstream of the water conservancy project to prevent the flow of water in the river channel, thereby facilitating the maintenance work of the water conservancy project by construction personnel downstream. At this time, the water-blocking mechanism 1 can block the flow of water in the river channel, the hydraulic rod 3 moves upward, and the support mechanism 2 is opened by the support rod 4, which can facilitate the workers to transport materials to both banks of the river.

[0030] The support mechanism 2 includes a fixed plate 21. A top guard plate 22 is fixedly connected to the upper surface of the fixed plate 21. A spraying component 29 is fixedly connected to the inner surface of the top guard plate 22. A support plate 23 is provided at the bottom of the spraying component 29. A side plate 24 is slidably connected to the inner surface of the support plate 23. The lower surface of the side plate 24 is rotatably connected to the top end of the support rod 4. The outer surfaces of both sides of the fixed plate 21 are rotatably connected to the inner surface of the support plate 23 on the side away from the side plate 24. A V-shaped movable rod 25 is rotatably connected to the inner surface of the support plate 23. The end of the V-shaped movable rod 25 away from the support plate 23 is rotatably connected to the outer surface of the side plate 24. The upper surface of the support plate 23 is in contact with the lower surface of the top guard plate 22. A sliding rod 26 is rotatably connected to the outer surface of the V-shaped movable rod 25. A sleeve 27 is slidably connected to the outer surface of the sliding rod 26. The internal structure is equipped with a tension spring 28. Both ends of the tension spring 28 are fixedly connected to the end of the sliding rod 26 away from the V-shaped movable rod 25. In use, the hydraulic rod 3 installed in the groove 12 moves upward and pushes the support plate 23 to rotate along the surface of the fixed plate 21 through the support rod 4. When the upper surface of the support plate 23 contacts the lower surface of the top guard plate 22, the surface of the support plate 23 is horizontal with the surface of the top guard plate 22, and the support plate 23 cannot continue to flip upward. Then, as the hydraulic rod 3 continues to move upward, the support rod 4 can drive the side plate 24 to slide out from the support plate 23. At this time, the opening of the V-shaped movable rod 25 becomes larger, the sliding rod 26 slides outward along the inner surface of the sleeve 27, and the tension spring 28 is stretched. Then, the material can be transported through the top guard plate 22, the support plate 23 and the side plate 24.

[0031] The spraying component 29 includes a spray pipe 291. A fixing ring 293 is fixedly connected to the inner surface of the spray pipe 291. A rectangular sleeve 296 is slidably connected to the inner surface of the fixing ring 293. A push plate 294 is fixedly connected to the outer surface of the rectangular sleeve 296 away from the fixing ring 293. The outer surface of the push plate 294 is slidably connected to the inner surface of the spray pipe 291. A rectangular nozzle 292 is fixedly connected to the outer surface of the spray pipe 291. A limit ring 298 is fixedly connected to the inner surface of the spray pipe 291. The outer surface of the limit ring 298 contacts the outer surface of the push plate 294. A compression spring 295 is fixedly connected to the outer surface of the push plate 294. The end of the compression spring 295 away from the push plate 294 is fixedly connected to the outer surface of the fixing ring 293. A water passage hole 297 is opened in the wall of the rectangular sleeve 296. The outer surface of the spray pipe 291 is fixed to the inner surface of the top guard plate 22. When water flows into the support mechanism 2 through the suction pipe 161, the water can pass through the holes on the surface of the top guard plate 22 and into the spray component 29. As the amount of water entering gradually increases, the pressure in the spray pipe 291 gradually increases. The water entering the spray pipe 291 pushes the push plate 294 to slide towards the side closer to the fixing ring 293. At this time, the rectangular sleeve 296 moves together with the push plate 294, and the compression spring 295 is compressed. The water can then be sprayed out from the surface of the rectangular nozzle 292 after passing through the water passage 297. The limiting ring 298 restricts the movement stroke of the push plate 294. The rectangular nozzle 292 can change the position of the water when it is sprayed out, increasing the coverage area of ​​the water when it is sprayed out. This allows the surfaces of the support plate 23 and the side plate 24 to be rinsed, preventing silt from remaining on the surfaces of the support plate 23 and the side plate 24 when the workers are transporting materials.

[0032] The water-blocking mechanism 1 includes a gate 11. The inner surface of the gate 11 is fixedly connected to the lower surface of the hydraulic rod 3 via a groove 12, and the groove 12 is formed in the wall of the gate 11. A pneumatic push rod 13 is fixedly connected to the inner surface of the top of the gate 11. A water-blocking plate 14 is fixedly connected to the output end of the pneumatic push rod 13. A limit plate 17 is slidably connected to the outer surface of the water-blocking plate 14. A filter screen 15 is fixedly connected to the outer surface of the limit plate 17. The outer surface of the filter screen 15 is fixedly connected to the outer surface of the gate 11. The upper surface of the gate 11 is fixedly connected to the lower surface of the fixing plate 21. The outer surface of the limit plate 17 is fixedly connected to the inner surface of the gate 11. The inner surface of the gate 11 is slidably connected to the outer surface of the water-blocking plate 14. A draining rod 18 is fixedly connected to the outer surface of the water-blocking plate 14. The outer surface of the draining rod 18 is fixedly connected to the filter screen 14. The inner surface of the gate 11 is slidably connected, and the inner surface of the gate 11 is fixedly connected to the suction component 16. The outer surface of the suction component 16 is fixedly connected to the inner surface of the limiting plate 17. When a small amount of water needs to flow from the river channel, the pneumatic push rod 13 can drive the water blocking plate 14 to slide upward along the inner surface of the limiting plate 17, so that the water can flow through the surface of the filter screen 15. During the upward movement of the water blocking plate 14, the unblocking rod 18 moves upward with the water blocking plate 14 to prevent silt from accumulating at the bottom of the gate 11 and clogging the filter screen 15. By controlling the upward movement distance of the water blocking plate 14 by the pneumatic push rod 13, the flow rate of the water in the river channel can be adjusted. At the same time, the suction component 16 transports part of the water flow to the support mechanism 2 to facilitate the rinsing of the surface of the support mechanism 2.

[0033] The suction component 16 includes a suction pipe 161, a half-shell 162 fixedly connected to the bottom end of the suction pipe 161, a rotating shaft 163 rotatably connected to the inner surface of the half-shell 162, a spiral blade 164 fixedly connected to the outer surface of the rotating shaft 163, the outer surface of the spiral blade 164 rotatably connected to the inner surface of the suction pipe 161, a baffle 167 fixedly connected to the outer surface of the rotating shaft 163, the outer surface of the suction pipe 161 fixedly connected to the inner surface of the gate 11, the inner surface of the gate 11 fixedly connected to the lower surface of the half-shell 162, a filter plate 166 fixedly connected to the inner surface of the suction pipe 161, the inner surface of the filter plate 166 rotatably connected to the outer surface of the rotating shaft 163, and a scraper 165 fixedly connected to the outer surface of the rotating shaft 163. The outer surface of the bottom of the scraper 165... The upper surface of the filter plate 166 is rotatably connected to the upper surface of the suction pipe 161, and the inner surface of the top of the suction pipe 161 is fixedly connected to the inner surface of the fixed plate 21. When the water flows through the gate 11, the water flow is driven by the turbulence of the half shell 162 to rotate the turbulence fan 167 in one direction. At this time, the turbulence fan 167 can drive the spiral blade 164 to rotate through the rotating shaft 163, and transport part of the water flow through the suction pipe 161 to the support mechanism 2 so as to wash the surface of the support mechanism 2. During this process, the filter plate 166 can filter the water flow entering the suction pipe 161 to ensure that the mud and sand at the bottom of the river will not be sprayed onto the surface of the support mechanism 2 when washing the support mechanism 2. At the same time, the scraper 165 rotates with the rotating shaft 163 to prevent the surface of the filter plate 166 from being blocked.

[0034] Working principle: The device is inserted into the river channel upstream of the water conservancy project to stop the flow of water in the river channel, thereby facilitating the maintenance work of the water conservancy project downstream by the construction personnel. At this time, the water blocking mechanism 1 can block the flow of water in the river channel, the hydraulic rod 3 moves upward and opens the support mechanism 2 through the support rod 4, which can facilitate the workers to transport materials to both sides of the river channel.

[0035] In use, the hydraulic rod 3 installed in the groove 12 moves upward and pushes the support plate 23 to rotate along the surface of the fixed plate 21 through the support rod 4. When the upper surface of the support plate 23 contacts the lower surface of the top guard plate 22, the surface of the support plate 23 is horizontal with the surface of the top guard plate 22, and the support plate 23 cannot continue to flip upward. Then, as the hydraulic rod 3 continues to move upward, the support rod 4 can drive the side plate 24 to slide out from the support plate 23. At this time, the opening of the V-shaped movable rod 25 becomes larger, the sliding rod 26 slides outward along the inner surface of the sleeve 27, and the tension spring 28 is stretched. Then, the material can be transported through the top guard plate 22, the support plate 23 and the side plate 24, thereby increasing the horizontal unfolding area of ​​the entire support mechanism 2, making it convenient for workers to transport materials to both sides of the river.

[0036] When a small amount of water needs to flow from the river channel, the pneumatic push rod 13 can drive the water-blocking plate 14 to slide upward along the inner surface of the limiting plate 17, allowing the water to flow through the surface of the filter screen 15. During the upward movement of the water-blocking plate 14, the unblocking rod 18 moves upward along with the water-blocking plate 14 to prevent silt from accumulating at the bottom of the gate 11 and clogging the filter screen 15. By controlling the upward movement distance of the water-blocking plate 14 through the pneumatic push rod 13, the flow rate of the water in the river channel can be adjusted. At the same time, the suction component 16 transports part of the water flow to the support mechanism 2 to facilitate the rinsing of the surface of the support mechanism 2.

[0037] When the water flows through the gate 11, the water flow is driven by the turbulence of the half shell 162 to rotate the turbulence fan 167 in one direction. At this time, the turbulence fan 167 can drive the spiral blade 164 to rotate through the rotating shaft 163, and transport part of the water flow to the support mechanism 2 through the suction pipe 161 so as to wash the surface of the support mechanism 2. During this process, the filter plate 166 can filter the water flow entering the suction pipe 161 to ensure that the mud and sand at the bottom of the river will not be sprayed onto the surface of the support mechanism 2 when washing the support mechanism 2. At the same time, the scraper 165 rotates with the rotating shaft 163 to prevent the surface of the filter plate 166 from being blocked.

[0038] When water flows into the support mechanism 2 through the suction pipe 161, the water can pass through the holes opened on the surface of the top guard plate 22 and into the spray component 29. At this time, as the amount of water entering gradually increases, the pressure in the spray pipe 291 gradually increases. The water entering the spray pipe 291 pushes the push plate 294 to slide towards the side closer to the fixed ring 293. At this time, the rectangular sleeve 296 moves together with the push plate 294, and the compression spring 295 is compressed. The water can then be sprayed out from the surface of the rectangular nozzle 292 after passing through the water passage 297. The limiting ring 298 restricts the movement stroke of the push plate 294. The rectangular nozzle 292 can change the position of the water when it is sprayed out, increasing the coverage area of ​​the water when it is sprayed out. This allows the surfaces of the support plate 23 and the side plate 24 to be rinsed, preventing silt from remaining on the surfaces of the support plate 23 and the side plate 24 when workers are transporting materials.
