Description
Technical Field
[0001] This invention belongs to the field of water conservancy engineering gate technology, specifically referring to an adjustable lifting water conservancy engineering gate. Background Technology
[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits; they are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways to achieve their objectives.
[0003] In actual production and daily life, flood discharge is usually achieved by closing and opening lifting gates in water conservancy projects. However, current lifting gates in water conservancy projects generally do not have the function of emergency active flood discharge, which increases the risk of flood disasters. Furthermore, due to the infrequent use of the gates, the lifting pistons are prone to failure, which can easily lead to accidents where the gates cannot be opened. Therefore, the market urgently needs an adjustable lifting gate in water conservancy projects to solve the above problems. Summary of the Invention
[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an adjustable lifting gate for water conservancy projects. This effectively solves the problem that current lifting gates typically lack emergency active flood discharge capabilities, increasing the risk of flooding. Furthermore, due to the infrequent use of the gate, the lifting piston is prone to failure, easily leading to the gate's inability to open. By incorporating an active flood discharge assembly and a gate assembly, the active opening and flood discharge function of the water conservancy project gate can be achieved solely through mechanical structures without the need for liquid level sensors. This effectively reduces the risk of flooding caused by untimely gate opening. Moreover, by pulling the emergency control rope, the gate body can quickly slide upwards along the inner side of the side frame, effectively avoiding the problem of the gate failing to open.
[0005] The technical solution adopted by this invention is as follows: This invention proposes an adjustable lifting gate for water conservancy projects, including an active flood discharge assembly, a gate assembly, and a gate body assembly. The active flood discharge assembly is located on the gate body assembly, and the gate assembly is located inside the gate body assembly. The active flood discharge assembly is located at the upper part of the gate assembly. The active flood discharge assembly includes an active flood discharge control component, a gate lifting power component, and an emergency flood discharge control component. The gate assembly includes a gate body, and the gate body assembly includes a side gate frame and an upper gate frame. The active flood discharge control component is located inside the gate body, the gate lifting power component is located on the side gate frame, and the emergency flood discharge control component is located on the upper gate frame. The upper gate frame is bolted to the side gate frame, and the gate body is located inside the side gate frame. By setting up the active flood discharge assembly and the gate assembly, the function of emergency active gate opening and flood discharge of water conservancy projects can be realized through mechanical structure without the need for liquid level sensors, thereby effectively reducing the risk of flood disasters caused by untimely gate opening operations.
[0006] Furthermore, the active flood discharge control component includes a pressure relief control plate, a U-shaped block, an intermediate steel rope, a connecting rod, a control latch, a control reset spring, a power push rod, a damping rod body, a rotating handle, a pressure adjusting spring, a slider body, an installation handle, and a sealing plate. One end of the U-shaped block is bolted to the pressure relief control plate, and the other end of the U-shaped block is latched to the intermediate steel rope. Both ends of the intermediate steel rope are provided with steel rope connectors, which are fixedly connected to the connecting rod. The control latch is fixedly connected to the connecting rod. The control reset spring is located on the outside of the connecting rod, and the sealing plate is located on the outside of the connecting rod. By setting up the active flood discharge control component and the gate lifting power component, the two cooperate with each other. When the flood impacts the pressure relief control plate, the intermediate steel rope pulls the control latch away from the limit groove through the connecting rod, thereby realizing the active lifting function of the gate body and thus realizing the active gate opening and flood discharge function of this device.
[0007] One end of the power push rod is fixedly connected to the pressure relief control plate, and the other end of the power push rod is threadedly connected to the damping rod body. The rotating handle is fixedly connected to the damping rod body, the pressure adjusting spring is located outside the damping rod body, the slider body is fixedly connected to the power push rod, and the mounting handle is fixedly connected to the connecting rod. By rotating the rotating handle, the damping rod body is rotated, thereby adjusting the preload of the pressure adjusting spring. This allows the device to adapt to rivers with different flow rates, effectively expanding the applicable range of water conservancy project gates.
[0008] Furthermore, the gate lifting power assembly includes a power hydraulic piston, a hydraulic piston mounting flange, a power reset spring, and a spring mounting flange. One end of the power hydraulic piston is fixedly connected to the hydraulic piston mounting flange, and one end of the power reset spring is fixedly connected to the spring mounting flange. Both the power reset spring and the spring mounting flange are provided in two sets.
[0009] Furthermore, the emergency flood discharge control component includes an upper pull rope, an emergency control pull rope, a housing, an upper pulley body, and an upper pulley mounting bracket. The upper pull rope is fixedly connected to the emergency control pull rope. The housing is located outside the upper pull rope, and the emergency control pull rope is located outside the upper pulley body. The upper pulley body is rotatably connected to the interior of the upper pulley mounting bracket via a rotating shaft. By setting up the emergency flood discharge control component, the emergency flood discharge control component pulls the control block in the active flood discharge control component out of the limit groove. Since the power reset spring is in a stretched state when the gate is closed, the automatic rising function of the gate body is realized, avoiding the failure of the gate to open due to damage to the power hydraulic piston.
[0010] Furthermore, the gate assembly includes a sliding wheel mounting bracket, a sliding wheel body, and a damping rod mounting bracket. A control component mounting slot is provided in the upper middle part of the gate body. One end of the sliding wheel mounting bracket is fixedly connected to the gate body, and the other end of the sliding wheel mounting bracket is rotatably connected to the sliding wheel body via a rotating shaft. The damping rod mounting bracket is fixedly connected to the gate body. A locking block groove is provided through the interior of the gate body, and a side sliding groove is provided on the side of the control component mounting slot.
[0011] Furthermore, the door assembly includes an upper control pull rope, which is bolted to the upper door frame. There are two sets of upper control pull ropes, and a limit groove is provided through the side of the side door frame.
[0012] Furthermore, the pressure relief control plate is located in the control component mounting slot, the slider body is located in the side sliding groove, the damping rod body is slidably connected in the damping rod mounting bracket, the control reset spring is located between the control block and the sealing plate, and the pressure adjusting spring is located between the damping rod mounting bracket and the power push rod.
[0013] Furthermore, the control block is slidably connected in the block groove, one end of the control block is engaged in the limiting groove, and the sealing plate is provided on the side of the control component mounting groove and located at one end of the block groove.
[0014] Furthermore, the upper end of the power hydraulic piston is bolted to the upper gate frame via a flange, the hydraulic piston mounting flange is bolted to the gate body, one end of the power reset spring is fixedly connected to the upper control pull rope, the spring mounting flange is bolted to the gate body, one end of the upper pull rope is located outside the lower pulley body and fixedly connected to the mounting handle, and the upper pulley mounting bracket is fixedly connected to the upper gate frame. By setting up the active flood discharge assembly and the gate assembly, the gate body can be quickly slid upward along the inner side of the side gate frame simply by pulling the emergency control pull rope, thereby effectively avoiding the problem of the gate being unable to open.
[0015] The beneficial effects achieved by the present invention using the above structure are as follows:
[0016] (1) In order to solve the problem that the current lifting water conservancy project gate does not have the function of emergency active flood discharge, which increases the risk of flood disaster, the present invention sets up an active flood discharge assembly and a gate assembly. The function of emergency active gate opening and flood discharge can be realized by mechanical structure alone without the need for liquid level sensors, etc., thereby effectively reducing the risk of flood disaster caused by untimely gate opening operation;
[0017] (2) Among them, by setting an active flood discharge control component and a gate lifting power component, the two cooperate with each other. The flood impacts the pressure relief control plate, and then the middle steel rope pulls the control block away from the limit groove through the connecting rod, thereby realizing the active lifting function of the gate body, and thus realizing the active gate opening and flood discharge function of this device.
[0018] (3) In addition, by rotating the rotating handle, the damping rod body is rotated, thereby adjusting the preload of the pressure regulating spring, so that the device can be adapted to rivers with different flow rates, effectively expanding the applicable range of water conservancy project gates;
[0019] (4) In order to solve the problem that the existing gates are used less often and the lifting piston is prone to failure, which in turn makes the gate unable to open, the present invention sets up an active flood discharge assembly and a gate assembly. Only by pulling the emergency control rope, the gate body can be quickly slid upward along the inner side of the side gate frame, thereby effectively avoiding the problem that the gate cannot be opened.
[0020] (5) In this case, by setting up an emergency flood discharge control component, the control block in the active flood discharge control component is pulled out of the limit groove by the emergency flood discharge control component. Since the power reset spring is in a stretched state when the gate is closed, the gate body can automatically rise, thus avoiding the failure of the gate to be opened due to damage to the power hydraulic piston.

[0040] like Figures 1-15As shown, this invention proposes an adjustable lifting gate for hydraulic engineering, comprising an active flood discharge assembly 1, a gate assembly 2, and a gate body assembly 3. The active flood discharge assembly 1 is mounted on the gate body assembly 3, and the gate assembly 2 is located inside the gate body assembly 3. The active flood discharge assembly 1 is situated above the gate assembly 2. The active flood discharge assembly 1 includes an active flood discharge control component 11, a gate lifting power component 12, and an emergency flood discharge control component 13. The gate assembly 2 includes a gate body 200, and the gate body assembly 3 includes a side gate frame 300 and an upper gate frame 301. The active flood discharge control component 11 is located inside the gate body 200, and the gate lifting power component 12... Component 12 is installed on the side gate frame 300, and emergency flood discharge control component 13 is installed on the upper gate frame 301. The upper gate frame 301 is bolted to the side gate frame 300, and the gate body 200 is installed inside the side gate frame 300. In order to solve the problem that the current lifting water conservancy project gate does not have the function of active flood discharge, thus increasing the risk of flood disasters, this invention sets up an active flood discharge assembly 1 and a gate assembly 2. The function of emergency active gate opening and flood discharge of water conservancy project gate can be realized by mechanical structure alone without the need for liquid level sensors, thereby effectively reducing the risk of flood disasters caused by untimely gate opening operation.
[0041] The active flood discharge control component 11 includes a pressure relief control plate 110, a U-shaped block 111, an intermediate steel rope 112, a connecting rod 114, a control latch 115, a control reset spring 116, a power push rod 117, a damping rod body 118, a rotating handle 119, a pressure adjusting spring 1110, a slider body 1111, a mounting handle 1112, and a sealing plate 1113. One end of the U-shaped block 111 is bolted to the pressure relief control plate 110, and the other end of the U-shaped block 111 is latched to the intermediate steel rope 112. Both ends of the intermediate steel rope 112 are equipped with steel rope connections. The head 113, steel rope connector 113 is fixedly connected to the connecting rod 114, control block 115 is fixedly connected to the connecting rod 114, control reset spring 116 is located on the outside of the connecting rod 114, sealing plate 1113 is located on the outside of the connecting rod 114, one end of power push rod 117 is fixedly connected to pressure relief control plate 110, the other end of power push rod 117 is threadedly connected to damping rod body 118, rotating handle 119 is fixedly connected to damping rod body 118, and pressure adjustment is achieved by rotating rotating handle 119, thereby rotating damping rod body 118. The preload of the spring 1110 is adjusted to allow the device to adapt to rivers with different flow rates, effectively expanding the applicability of the gate in water conservancy projects. The pressure regulating spring 1110 is located outside the damping rod body 118. The slider body 1111 is fixedly connected to the power push rod 117, and the mounting handle 1112 is fixedly connected to the connecting rod 114. The gate lifting power assembly 12 includes a power hydraulic piston 120, a hydraulic piston mounting flange 121, a power reset spring 122, and a spring mounting flange 123. One end of the power hydraulic piston 120 is fixedly connected to the hydraulic piston mounting flange 123. The flange 121 is fixedly connected to the spring mounting flange 123 at one end of the dynamic reset spring 122. Both the dynamic reset spring 122 and the spring mounting flange 123 are provided in two sets. By setting the active flood discharge control component 11 and the gate lifting power component 12, the two cooperate with each other. When the flood impacts the pressure relief control plate 110, the intermediate steel rope 112 pulls the control block 115 away from the limit groove 303 through the connecting rod 114, thereby realizing the emergency active lifting function of the gate body 200, and thus realizing the emergency active gate opening flood discharge function of this device.
[0042] The emergency flood discharge control component 13 includes an upper pull rope 130, an emergency control pull rope 131, a housing 132, an upper pulley body 133, and an upper pulley mounting bracket 134. The upper pull rope 130 is fixedly connected to the emergency control pull rope 131. The housing 132 is located outside the upper pull rope 130, and the emergency control pull rope 131 is located outside the upper pulley body 133. The upper pulley body 133 is rotatably connected to the interior of the upper pulley mounting bracket 134 via a rotating shaft. The gate assembly 2 includes a lower pulley mounting bracket 202, a lower pulley body 203, and a damping rod mounting bracket 204. A control component mounting slot 201 is provided in the middle of the upper end of the gate body 200. One end of the lower pulley mounting bracket 202 is fixedly connected to the gate body 200, and the other end of the lower pulley mounting bracket 202 is rotatably connected to the lower pulley body via a rotating shaft. 203, the damping rod mounting bracket 204 is fixedly connected to the gate body 200. The gate body 200 has a through-hole sliding groove 205. The side of the control component mounting groove 201 has a side sliding groove 206. The gate assembly 3 includes an upper control pull rope 302, which is bolted to the upper gate frame 301. There are two sets of upper control pull ropes 302. The side of the side gate frame 300 has a limit groove 303. In order to solve the problem that the existing gates are used less often and the lifting piston fails, which easily causes the gate to be unable to open, the present invention sets an active flood discharge assembly 1 and a gate assembly 2. Only by pulling the emergency control pull rope 131 can the gate body 200 slide quickly upward along the inner side of the side gate frame 300, thereby effectively avoiding the problem of the gate being unable to open.
[0043] In addition, the pressure relief control plate 110 is located in the control component mounting groove 201, the slider body 1111 is located in the side sliding groove 206, the damping rod body 118 is slidably connected in the damping rod mounting bracket 204, the control reset spring 116 is located between the control block 115 and the sealing plate 1113, the pressure adjustment spring 1110 is located between the damping rod mounting bracket 204 and the power push rod 117, the control block 115 is slidably connected in the block sliding groove 205, one end of the control block 115 is engaged in the limiting groove 303, and the sealing plate 1113 is located on the side of the control component mounting groove 201 and at one end of the block sliding groove 205.
[0044] In this embodiment, the upper end of the power hydraulic piston 120 is bolted to the upper gate frame 301 via a flange, the hydraulic piston mounting flange 121 is bolted to the gate body 200, one end of the power reset spring 122 is fixedly connected to the upper control pull rope 302, the spring mounting flange 123 is bolted to the gate body 200, one end of the upper pull rope 130 is located outside the lower pulley body 203 and is fixedly connected to the mounting handle 1112, and the upper pulley mounting bracket 134 is fixedly connected to the upper gate frame 301. By setting the emergency flood discharge control component 13, the emergency flood discharge control component 13 pulls the control block 115 in the active flood discharge control component 11 out of the limit groove 303. Since the power reset spring 122 is in a stretched state when the gate is closed, the automatic rising function of the gate body 200 is realized, avoiding the failure of the gate to open due to damage to the power hydraulic piston 120.
[0045] In practical use, firstly, rotate the rotating handle 119 according to the river channel where the gate is located, then adjust the length of the damping rod body 118 relative to the power push rod 117, and then adjust the preload of the pressure regulating spring 1110. Then, operate the power hydraulic piston 120 so that the hydraulic piston mounting flange 121 drives the gate body 200 to slide down along the inner side of the side gate frame 300. When the control block 115 engages with the limit groove 303, the gate body 200 stops moving down.
[0046] When water conservancy engineers need to open the gate to release water, they pull the emergency control rope 131, causing the upper rope 130 to pull the connecting rod 114 through the mounting handle 1112 to move it towards the middle of the control component mounting groove 201. This causes the connecting rod 114 to pull the control block 115 to slide along the block slide groove 205 until one end of the control block 115 disengages from the limit groove 303. Then, the power hydraulic piston 120 is operated, causing it to pull the gate body 200 upward through the hydraulic piston mounting flange 121, thereby realizing the gate's function of opening the gate to release floodwater.
[0047] When the river water rises too quickly and the operator fails to respond in time, the water flow first pushes the pressure relief control plate 110. The power push rod 117 slides along the side sliding groove 206 through the slider body 1111. Then, the U-shaped block 111 pushes the middle steel rope 112. The middle steel rope 112 pulls the connecting rods 114 at both ends to move towards the middle of the control component mounting groove 201. Since the connecting rods 114 are fixedly connected to the control block 115, the control block 115 slides along the block sliding groove 205 and gradually separates from the limit groove 303. When the control block 115 is separated from the limit groove 303, the power reset spring 122 pulls the gate body 200 upward through the spring mounting flange 123, thereby realizing the emergency active flood discharge function of the gate body 200.
[0048] When the power hydraulic piston 120 is damaged and loses power, simply pull the emergency control rope 131. The upper pull rope 130 pulls the connecting rod 114 through the mounting handle 1112 to move it towards the middle of the control component mounting groove 201. This causes the connecting rod 114 to pull the control block 115 to slide along the block slide groove 205 until one end of the control block 115 disengages from the limit groove 303. The power reset spring 122 then pulls the gate body 200 upward through the spring mounting flange 123, thereby realizing the gate body 200's flood discharge function and avoiding the problem of the gate being unable to open.
