Description

Technical Field

[0001] This utility model belongs to the field of hydraulic gate technology, and in particular relates to a double-sided grid type hydraulic lifting gate. Background Technology

[0002] Hydraulic gates are control facilities used to close and open water discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, and discharge sediment and floating debris. Hydraulic gates are frequently used in water conservancy projects to control the water storage of rivers, canals and reservoirs.

[0003] In existing technologies, conventional hydraulic gates control flow through a single gate plate. After opening the gate, scum accumulated on the inflow side is easily carried out with the water flow, hindering effective scum collection. Furthermore, the presence of scum may interfere with the normal closure of the gate plate, thus reducing the overall airtightness of the hydraulic gate. To address these issues, we provide a double-sided grid-type hydraulic lifting gate. Utility Model Content

[0004] The purpose of this utility model is to provide a double-sided grid-type hydraulic lifting gate. Through the specific structural design of the gate body mechanism, gate plate body, double grid mechanism and steel cable, it solves the problem that existing hydraulic gates are prone to causing the scum accumulated on the inflow side to flow out with the water after the gate is opened, thus making it impossible to effectively collect the scum. At the same time, the presence of scum may affect the normal closing of the gate plate, thereby reducing the airtightness of the entire hydraulic gate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a double-sided grid-type hydraulic lifting gate, including a gate body mechanism. The gate body mechanism includes two lifting guide rails arranged opposite to each other. A gate plate body is slidably arranged between the lifting guide rails. The gate plate body is driven by a steel cable lifting assembly at the top of the gate body mechanism. A double grid mechanism is slidably arranged between the lifting guide rails. The gate plate body is slidably arranged inside the double grid mechanism. When the gate plate body rises to the point where it is completely misaligned with the grid mesh on the double grid mechanism, the grid mesh on the double grid mechanism is used for flow passage. When the gate plate body rises to the point where it is in contact with the top of the double grid mechanism, the gate plate body is used to drive the double grid mechanism to rise synchronously to open the gate.

[0006] In this embodiment of the present invention, the gate mechanism further includes a gate base, two vertical gate plates are symmetrically fixedly arranged on the top of the gate base, a gate plate support seat located between the two vertical gate plates is fixedly arranged on the top of the gate base, and the lifting guide rail is fixedly arranged on the inner side wall of the vertical gate plate.

[0007] In this embodiment of the present invention, the cable lifting assembly includes a horizontal support platform fixedly mounted on the top of the vertical gate plate. Two U-shaped mounting plates are fixedly installed on the top of the horizontal support platform. The top of the horizontal support platform has cable guides corresponding to the U-shaped mounting plates. A lifting power shaft is rotatably mounted on the inner side of the U-shaped mounting plates. A cable winding wheel is fixedly mounted on the circumferential side of the lifting power shaft. The movable end of the cable wound on the cable winding wheel passes through the cable guide and is fixedly connected to the gate plate body.

[0008] In this embodiment of the present invention, a lifting motor is fixedly installed on one side of one of the U-shaped mounting plates. The output end of the lifting motor is connected to the corresponding lifting power shaft. A synchronous sprocket is fixedly installed at the end of the lifting power shaft away from the lifting motor. The two synchronous sprockets are connected by a synchronous chain.

[0009] In this embodiment of the present invention, the double-grid mechanism includes two symmetrically arranged intercepting plates, the gate body is disposed between the intercepting plates and fits against each other, the intercepting plates are slidably disposed between the lifting guide rails, the two intercepting plates are connected by a fixing plate, the surface of the intercepting plates is provided with a grid mesh, and a scum cleaning plate with a mesh structure is fixedly installed at the bottom of the intercepting plates.

[0010] In this embodiment of the present invention, the top of the gate support is provided with a gate sealing groove located between two lifting guide rails. One side of the gate sealing groove is provided with an air supply pipe fixed to the corresponding vertical gate plate. An air supply device is fixedly installed on the top of the horizontal support platform. The air outlet of the air supply device is connected to an air supply pipe that communicates with the air supply pipe. The gate support is provided with a flow guide cavity located below the gate sealing groove. The flow guide cavity is connected to the air supply pipe through an air guide port. The flow guide cavity is connected to the gate sealing groove through several aeration holes.

[0011] This utility model has the following beneficial effects: 1. This utility model uses a lifting motor to control the synchronous rotation of two steel cable winding wheels, driving the gate body to rise along the lifting guide rail until the gate body is in contact with the fixed plate on the double grid mechanism. At this time, the gate body is completely misaligned with the grid mesh, and the entire gate is in the first stage of opening. The grid mesh on both sides of the gate body can not only allow flow but also effectively intercept scum from different sides to protect the gate body. This greatly avoids the impact of scum on the gate body's closing action. When the lifting motor is restarted to drive the gate body to move upward, the upward-moving gate body drives the entire double grid mechanism to move upward synchronously for a distance, thus realizing the second stage of opening of the entire gate. During this process, the scum cleaning plate can push the scum on both sides of the gate away from the water surface to prevent the scum from flowing out with the water flow during the opening process.

[0012] 2. In the process of gradually closing the gate by controlling the downward movement of the gate body, air is supplied to the air delivery pipeline through the air supply equipment and air supply pipeline. The air flow in the air delivery pipeline enters the guide cavity along the air guide port, and is then sprayed out by each aeration hole to achieve a flushing cleaning of the inner cavity of the gate sealing groove until the gate body moves downward and is reinserted into the gate sealing groove to complete the closure. At this time, the air supply equipment is turned off and the two flow plates on the double grid mechanism abut against the top of the gate support seat again. This can effectively avoid the impact of impurities accumulated in the gate sealing groove during the closure or opening process on the closure of the gate body, thereby ensuring the airtightness when the gate body and the gate sealing groove are in contact.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7 This utility model is a double-sided grid-type hydraulic lifting gate, including a gate body mechanism 1; the gate body mechanism 1 includes two lifting guide rails 101 arranged opposite to each other, and a gate plate body 2 is slidably arranged between the lifting guide rails 101. The gate plate body 2 is driven by a steel cable lifting assembly at the top of the gate body mechanism 1; a double grid mechanism 3 is slidably arranged between the lifting guide rails 101, and the gate plate body 2 is slidably arranged inside the double grid mechanism 3. When the gate plate body 2 rises to be completely misaligned with the grid mesh 303 on the double grid mechanism 3, the grid mesh 303 on the double grid mechanism 3 is used for flow passage. When the gate plate body 2 rises to be in contact with the top of the double grid mechanism 3, the gate plate body 2 is used to drive the double grid mechanism 3 to rise synchronously to open the gate.

[0025] In this embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the gate mechanism 1 also includes a gate base 102, which is used to install on the concrete foundation at the bottom of the water to achieve a stable installation of the entire gate mechanism 1. Two vertical gate plates 103 are symmetrically fixed on the top of the gate base 102. The vertical gate plates 103 are attached to the side wall of the concrete foundation. A gate plate support seat 104 located between the two vertical gate plates 103 is fixed on the top of the gate base 102. The lifting guide rail 101 is fixed on the inner side wall of the vertical gate plate 103.

[0026] In this embodiment of the present invention, such as Figure 1 and Figure 3As shown, the cable lifting assembly includes a horizontal support platform 105 fixedly mounted on the top of the vertical gate plate 103. The horizontal support platform 105 is mounted on an external support foundation (existing technology). Two U-shaped mounting plates 106 are fixedly mounted on the top of the horizontal support platform 105. The top of the horizontal support platform 105 has cable guides 107 corresponding to the U-shaped mounting plates 106. A lifting power shaft 108 is rotatably mounted on the inner side of the U-shaped mounting plates 106. A cable winding wheel 109 is fixedly mounted on the circumference of the lifting power shaft 108. The movable end of the cable 4 wound on the cable winding wheel 109 passes through the cable guide 107 and is fixedly connected to the gate body 2.

[0027] Furthermore, a lifting motor 110 is fixedly installed on one side of one of the U-shaped mounting plates 106. The output end of the lifting motor 110 is connected to the corresponding lifting power shaft 108. A synchronous sprocket 111 is fixedly installed at the end of the lifting power shaft 108 away from the lifting motor 110. The two synchronous sprockets 111 are connected by a synchronous chain 112. When the lifting motor 110 is started, the lifting motor 110 controls the rotation of the corresponding lifting power shaft 108. Under the combined action of the synchronous sprocket 111 and the synchronous chain 112, the two lifting power shafts 108 rotate synchronously, thereby realizing the synchronous rotation of the two steel cable winding wheels 109. In this way, the gate body 2 can be controlled to move up and down along the lifting guide rail 101.

[0028] In this embodiment of the present invention, such as Figure 2 and Figure 7 As shown, the double-grid mechanism 3 includes two symmetrically arranged intercepting plates 301. The gate body 2 is disposed between the intercepting plates 301 and fits against each other (to improve the gate's sealing performance). The intercepting plates 301 are slidably disposed between the lifting guide rails 101. The two intercepting plates 301 are connected by a fixing plate 302. A grid mesh 303 is provided on the surface of the intercepting plate 301. A scum cleaning plate 304 with a mesh structure is fixedly installed at the bottom of the intercepting plate 301 (the scum cleaning plate 304 is below the water surface). The grid mesh 303 on one side of the double-grid mechanism 3 is used to intercept scum on the inflow side, while the grid mesh 303 on the other side of the double-grid mechanism 3 is used to intercept scum on the outflow side. This double-grid interception method avoids the impact of scum on the operation of the gate body 2.

[0029] When the gate is closed, the gate body 2 is at its lowest position under the action of the steel cable 4. The two flow-blocking plates 301 on the double-grid mechanism 3 abut against the top of the gate support 104 under their own weight. At this time, the grid mesh 303 on the two flow-blocking plates 301 on the double-grid mechanism 3 is blocked by the gate body 2, and the entire gate is in the closed state. When the lifting motor 110 is started, the corresponding lifting power shaft 108 is rotated by the lifting motor 110. Under the combined action of the synchronous sprocket 111 and the synchronous chain 112, the two lifting power shafts 108 are rotated synchronously, thereby realizing the synchronous rotation of the two steel cable winding wheels 109. In this way, the gate body 2 can be controlled to rise along the lifting guide rail 101 until the gate body 2 is in contact with the fixing plate 302 on the double-grid mechanism 3. The gate body 2 is completely misaligned with the grid 303, and the entire gate is in the first stage of opening. The grid 303 on both sides of the gate body 2 can not only allow flow but also effectively intercept scum from different sides to protect the gate body 2. This greatly avoids the impact of scum on the gate body 2's closing action. When the lifting motor 110 is restarted to drive the gate body 2 to move upward, the upward-moving gate body 2 drives the entire double grid mechanism 3 to move upward a certain distance (set by the system). This achieves the second stage of opening the entire gate. During this process, the scum cleaning plate 304 can push the scum on both sides of the gate away from the water surface to prevent the scum from flowing out with the water during the opening process, further reducing the interference of scum on the movement of the gate body 2.

[0030] Specific embodiment two, based on specific embodiment one, such as Figure 3 and Figure 6As shown, the gate support 104 has a gate sealing groove 113 located between the two lifting guide rails 101 at its top. The gate body 2, in the closed state, is inserted into the gate sealing groove 113. An air supply pipe 114, fixed to the corresponding vertical gate plate 103, is provided on one side of the gate sealing groove 113. An air supply device 115 is fixedly installed on the top of the horizontal support platform 105. The air outlet of the air supply device 115 is connected to an air supply pipe 116 connected to the air supply pipe 114. A guide cavity 117 is provided inside the gate support 104 below the gate sealing groove 113. The guide cavity 117 is connected to the air supply pipe 114 via an air inlet 118. The guide cavity 117 is connected to the gate sealing groove 113 via several aeration holes 119. When the gate body 2 moves downwards... During the gradual closing process, air is supplied to the air delivery pipe 114 through the air supply device 115 and the air supply pipe 116. The air flow in the air delivery pipe 114 enters the guide cavity 117 along the air guide port 118, and is then sprayed out by each aeration hole 119 to achieve flushing cleaning of the inner cavity of the gate sealing groove 113 until the gate body 2 moves downward and is re-inserted into the gate sealing groove 113 to complete the closing. At this time, the air supply device 115 is turned off and the two cut-off plates 301 on the double grid mechanism 3 abut against the top of the gate support seat 104. This effectively avoids the impact of impurities accumulated in the gate sealing groove 113 during the closing or opening process on the closing of the gate body 2, thereby ensuring the airtightness of the gate body 2 when it is in conjunction with the gate sealing groove 113.
