Description
Technical Field
[0001] This utility model relates to the field of gate technology, and in particular to an adjustable gate sealing device for water conservancy projects. Background Technology
[0002] Gates are indispensable key equipment in water conservancy projects. They are mainly used to control water flow, regulate water level, and prevent floods and drain water. The sealing performance of gates directly affects the operational stability and safety of water conservancy projects. If the seal is not tight, leakage and seepage are likely to occur, which will not only reduce the benefits of the project, but may also cause a series of problems such as gate corrosion and scouring of the surrounding foundation. In severe cases, it may even endanger the structural safety of the project.
[0003] Existing gate sealing devices for water conservancy projects are mostly fixed structures, achieving sealing primarily through a tight fit between sealing elements such as rubber gaskets and the gate frame. However, these fixed sealing devices have several drawbacks: Firstly, during long-term use, the sealing elements will experience a decline in sealing performance due to wear and aging, and the fixed structure cannot adjust or compensate for the sealing gap, requiring replacement of the sealing elements, which increases maintenance costs and workload. Secondly, during installation, there may be installation deviations or slight deformations under water pressure, and the fixed sealing device cannot adapt to these minor deviations, easily leading to localized incomplete sealing. Therefore, we propose an adjustable gate sealing device for water conservancy projects to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable gate sealing device for water conservancy projects.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable gate sealing device for hydraulic engineering includes a gate frame, a gate body, and a sealing mechanism. The gate frame is U-shaped, and an installation groove with an open top is provided on the inner wall of the gate frame. The gate body is slidably installed in the installation groove, and a sealing mechanism is connected between the gate body and the gate frame. The sealing mechanism includes a U-shaped groove, a U-shaped seat, and a sealing gasket. U-shaped grooves are provided on both sides of the gate body, and U-shaped seats are slidably installed in the U-shaped grooves. A sealing gasket is installed on one side of the U-shaped seat through a detachable structure, and the sealing gasket is in contact with the gate frame. The gate body has two through-type chambers, and the U-shaped grooves are connected to the chambers. A movable plate is slidably installed in the chamber. Four hinge rods are hinged to the bottom of the movable plate, and the bottom ends of the hinge rods are hinged to the corresponding U-shaped seats. Two synchronizing rods are fixedly installed on the side of the two movable plates that are close to each other. The gate body is provided with a pressing mechanism for pressing the movable plates.
[0006] Preferably, the extrusion mechanism includes a moving hole, an extrusion rod, and an extrusion plate. Two moving holes are provided on the top of the gate body. An extrusion rod is slidably installed in the moving hole. The bottom end of the extrusion rod is fixedly installed on the corresponding moving plate. The top ends of the two extrusion rods are fixedly installed on the same extrusion plate, which is located above the gate body.
[0007] Preferably, the top of the extrusion plate has two mounting holes, and the top of the gate body has two fixing screws fixedly installed, with the fixing screws passing through the corresponding mounting holes.
[0008] Preferably, a fixing nut is threaded onto the fixing screw, the extrusion plate is located between two fixing nuts, and multiple handles are installed in a ring at equal intervals on the outer side of the fixing nuts.
[0009] Preferably, the front and rear inner walls of the mounting groove are provided with T-shaped guide grooves with open tops, and T-shaped guide seats are fixedly installed on the front and rear sides of the gate body, and the T-shaped guide seats are slidably installed in the T-shaped guide grooves.
[0010] Preferably, the U-shaped seat has multiple screw slots, and the sealing gasket has multiple mounting holes, in which countersunk screws that are compatible with the screw slots are installed.
[0011] Preferably, two connecting frames are fixedly installed on the top of the gate body, and a drive mechanism for lifting and lowering the gate body is externally connected to the connecting frames.
[0012] The beneficial effects of this utility model are: 1. By setting up an extrusion mechanism, a moving plate, and a hinge rod, rotating the fixing nut can drive the extrusion plate to move up and down. The extrusion plate drives the moving plate to slide in the cavity through the extrusion rod. The moving plate pushes the U-shaped seat to slide in the U-shaped groove through the hinge rod, thereby moving the sealing gasket closer to or away from the gate frame to adjust the sealing gap. When the sealing gasket is worn or aged, resulting in a decrease in sealing performance, or when the gate has installation deviations or slight deformation, the sealing effect can be maintained by adjusting the sealing gap without immediately replacing the sealing gasket, thus reducing maintenance costs and workload. 2. The gasket is detachably connected to the U-shaped seat via a countersunk screw. When the gasket is severely worn and can no longer be used, the countersunk screw can be quickly removed to replace the gasket. Attached Figure Description

Detailed Implementation
[0015] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0016] This application discloses an adjustable gate sealing device for hydraulic engineering.
[0017] Reference Figure 1-6 An adjustable gate sealing device for water conservancy projects includes a gate frame 101, a gate body 103, and a sealing mechanism 2. The gate frame 101 is U-shaped, and an installation groove 102 with an open top is provided on the inner wall of the gate frame 101. The gate body 103 is slidably installed in the installation groove 102, and the sealing mechanism 2 is connected between the gate body 103 and the gate frame 101. The sealing mechanism 2 includes a U-shaped groove 201, a U-shaped seat 202 and a sealing gasket 203. U-shaped grooves 201 are provided on both sides of the gate body 103. A U-shaped seat 202 is slidably installed in the U-shaped groove 201. A sealing gasket 203 is installed on one side of the U-shaped seat 202 through a detachable structure. The sealing gasket 203 is in contact with the gate frame 101. The detachable structure includes screw slots 703, mounting holes 701, and countersunk screws 702. The U-shaped seat 202 has multiple screw slots 703, and the sealing gasket 203 has multiple mounting holes 701. A countersunk screw 702 that matches the screw slots 703 is installed in the mounting holes 701. The countersunk screws 702 enable the detachable connection between the sealing gasket 203 and the U-shaped seat 202.
[0018] In this embodiment, two through-type chambers 301 are provided on the gate body 103, and the U-shaped groove 201 is connected to the chambers 301. A movable plate 302 is slidably installed in the chambers 301. Four hinge rods 303 are hinged to the bottom of the movable plate 302. The bottom end of the hinge rods 303 is hinged to the corresponding U-shaped seat 202. Two synchronous rods 304 are fixedly installed on the side of the two movable plates 302 that are close to each other to ensure that the two movable plates 302 move synchronously.
[0019] In this embodiment, the gate body 103 is provided with a pressing mechanism for pressing the moving plate 302. The pressing mechanism includes a moving hole 401, a pressing rod 402, and a pressing plate 403. Two moving holes 401 are opened at the top of the gate body 103. The pressing rod 402 is slidably installed in the moving hole 401. The bottom end of the pressing rod 402 is fixedly installed on the corresponding moving plate 302. The top ends of the two pressing rods 402 are fixedly installed on the same pressing plate 403. The pressing plate 403 is located above the gate body 103. Two mounting holes 501 are opened at the top of the pressing plate 403. Two fixing screws 502 are fixedly installed at the top of the gate body 103. The fixing screws 502 pass through the corresponding mounting holes 501. Fixing nuts 503 are threaded on the fixing screws 502. The pressing plate 403 is located between the two fixing nuts 503. Multiple handles 504 are installed in a ring at equal intervals on the outer side of the fixing nuts 503 to facilitate the rotation of the fixing nuts 503.
[0020] In this embodiment, T-shaped guide grooves 601 with open tops are provided on the inner walls of the front and rear sides of the mounting groove 102. T-shaped guide seats 602 are fixedly installed on the front and rear sides of the gate body 103, and the T-shaped guide seats 602 are slidably installed in the T-shaped guide grooves 601 to guide the sliding of the gate body 103. Two connecting frames are fixedly installed on the top of the gate body 103. A drive mechanism for raising and lowering the gate body 103 is externally connected to the connecting frames. The gate body 103 can be raised and lowered through the drive mechanism. The drive mechanism is common knowledge in the art, such as electric drive and hydraulic drive, and will not be described in detail here.
[0021] In this utility model, during use, the gate body 103 is installed into the mounting groove 102 of the gate frame 101, and the T-shaped guide seat 602 is slidably installed in the T-shaped guide groove 601 to ensure the stability of the gate body 103 installation. In the initial state, the sealing gasket 203 is in contact with the gate frame 101 to achieve preliminary sealing. When the sealing gasket 203 is worn or aged, or when the gate has installation deviations or slight deformations that cause poor sealing, the upper fixing nut 503 can be rotated. Since the fixing nut 503 is threadedly connected to the fixing screw 502, rotating the fixing nut 503 can drive the extrusion plate 403 to move downward. The extrusion plate 403 pushes the moving plate 302 to slide downward in the chamber 301 through the extrusion rod 402. The moving plate 302 pushes the U-shaped seat 202 to slide outward in the U-shaped groove 201 through the hinge rod 303. The U-shaped seat 202 drives the sealing gasket 203 to move closer to the gate frame 101, reducing the sealing gap and ensuring the sealing effect. After the adjustment is completed, the lower fixing nut 503 can be rotated to make the fixing nut 503 abut against the extrusion plate 403, which can increase the stability of the extrusion plate 403. When the gasket 203 is worn out and can no longer be used, the old gasket 203 can be removed by disassembling the countersunk screw 702 and replaced with a new gasket 203, making maintenance convenient.
[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
