Description

Technical Field

[0001] This utility model relates to a water conservancy gate, and more particularly to an easy-opening large water conservancy gate, belonging to the field of water conservancy engineering technology. Background Technology

[0002] Hydraulic gates are important facilities installed on the water passage openings of hydraulic engineering projects to control water flow, regulate water level, and discharge floods. They come in various types, the most common being flat gates, arc gates, and flap gates. Flat gates have a simple structure and are easy to install and maintain, while arc gates have good hydrodynamic conditions and can withstand greater water pressure. Hydraulic gates typically consist of gate leaves, gate slots, and hoists. Gate leaves are responsible for blocking or releasing water flow, gate slots are used to guide and fix the gate leaves, and hoists provide power to open and close the gate.

[0003] In the prior art, such as the utility model application with application number 201922324890.2, a quick-opening hydraulic gate is disclosed. In order to solve the problem that the existing gate structure requires a long time to open the gate body, wastes a lot of manpower, and brings many inconveniences, the gate is designed to allow water on one side of the gate to flow quickly to the other side through the first and second drainage holes by cooperating with the baffle, the first drainage hole and the second drainage hole. The movement of the baffle is made more stable by cooperating with the limiting sleeve, the limiting rod and the limiting rod fixing bracket. The movement of the baffle can be controlled by cooperating with the second threaded rod, the retaining ring and the second turntable.

[0004] The above-mentioned applications still have shortcomings:

[0005] To facilitate the rapid opening of the gate, the baffle needs to be opened first during use. The opening of the baffle requires an independent lifting structure for control. Therefore, the entire gate has two lifting control structures, which is inconvenient during the opening and closing of the gate and affects the opening speed of the gate.

[0006] To address these issues, an easy-opening large-scale hydraulic gate was designed. Utility Model Content

[0007] The main purpose of this utility model is to provide an easy-to-open large hydraulic gate to solve the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] An easy-opening large hydraulic gate includes a portal frame and a gate slot inside the portal frame. A hoist is installed on the top of the portal frame, and a screw is vertically installed inside the hoist. A gate leaf is vertically slidably arranged between two sets of gate slots. A first through slot is opened on the front and rear ends of the gate leaf. A sliding groove is opened inside the gate leaf. A baffle is vertically slidably arranged inside the sliding groove. A second through slot is opened on the baffle to cooperate with the first through slot. A spring is provided between the top of the baffle and the inner top of the sliding groove. A rectangular sliding rod is fixed at the middle position of the top of the baffle. The rectangular sliding rod extends to the top of the gate leaf and is slidably connected to the gate leaf. The top end of the rectangular sliding rod is fixedly connected to the bottom end of the screw.

[0010] Preferably, gate water seals are vertically installed on both sides of the gate leaf end face, and the length of the gate water seal is the same as the length of the side of the gate leaf.

[0011] Preferably, inclined scrapers are evenly provided on both sides of the end face of the door leaf along the height direction, and the bottom end of the inclined scraper is inclined towards the first through groove.

[0012] Preferably, limit rods are vertically installed on both sides of the top of the baffle. The limit rods pass through the inside of the spring and extend to the top of the door leaf. The limit rods are slidably connected to the door leaf.

[0013] Preferably, a filter screen is provided between the inner sides of the first channel, and the outer side of the filter screen is flush with the end face of the door leaf.

[0014] Preferably, the front and rear ends of the door leaf are uniformly and vertically provided with bars, and the bars are located at the front end of the filter screen.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a baffle that slides vertically inside the gate leaf, with a spring between the top of the baffle and the sliding groove. The spring is in a stretched state when the gate leaf is closed. The top of the baffle is directly connected to the screw via a rectangular sliding rod. This allows the device to raise the baffle first and then the gate leaf when the gate is opened, using only the lifting structure composed of the hoist and the screw. This makes the gate opening control more convenient. Furthermore, when controlling the baffle to rise, the spring's restoring force makes the baffle rise more effortless, and the first and second through grooves can be connected more quickly to complete the gate opening.

[0017] 2. This utility model has inclined scrapers evenly arranged on both sides of the door leaf along the height direction, which can push out the silt or garbage inside the door groove during the process of controlling the door leaf to rise, thereby reducing the resistance when the door leaf rises.

[0033] Example 1

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an easy-opening large-scale hydraulic gate, including a portal frame 1 and a gate slot 101 opened inside the portal frame 1. A hoist 2 is installed on the top of the portal frame 1. A screw 3 is vertically installed inside the hoist 2. A gate leaf 4 is vertically slidably arranged between the two sets of gate slots 101. A first through groove 5 is opened on the front and rear ends of the gate leaf 4. A sliding groove 6 is opened inside the gate leaf 4. A baffle 7 is vertically slidably arranged inside the sliding groove 6. A second through groove 701 that cooperates with the first through groove 5 is opened on the baffle 7. A spring 703 is provided between the top of the baffle 7 and the inner top of the sliding groove 6. A rectangular sliding rod 702 is fixed at the middle position of the top of the baffle 7. The rectangular sliding rod 702 extends to the top of the gate leaf 4 and is slidably connected to the gate leaf 4. The top end of the rectangular sliding rod 702 is fixedly connected to the bottom end of the screw 3.

[0035] With the gate fully closed, the gate leaf 4 is inserted into the bottom of the gantry frame 1, and the baffle 7 moves down to the bottom of the slide groove 6. The first through groove 5 and the second through groove 701 are misaligned. At this time, the spring 703 is in a stretched state. When the gate needs to be opened, the hoist 2 is activated to control the screw 3 to move upward. In the initial stage, the upward movement of the screw 3 only drives the baffle 7 to move upward. At the same time, the upward movement of the baffle 7 is also subject to the tension of the spring 703. The upward movement of the baffle 7 is easier and more convenient to open. After the second through groove 701 of the baffle 7 is connected to the first through groove 5, the gate is in a low-flow-rate opening state. After the baffle 7 moves to the top of the slide groove 6, the spring 703 returns to its original position, and the second through groove 701 is fully aligned with the first through groove 5. If the screw 3 moves upward again, it will simultaneously control the upward movement of the gate leaf 4 and the baffle 7, increasing the opening range of the gate.

[0036] Example 2

[0037] The solution in Example 1 will be further described below with reference to its specific working method.

[0038] like Figure 4 As shown, in a preferred embodiment, based on the above method, a gate water seal 401 is vertically provided on both sides of the end face of the gate leaf 4, and the length of the gate water seal 401 is the same as the length of the side of the gate leaf 4. The use of the gate water seal 401 can ensure the sealing effect of the gate leaf 4.

[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, further, inclined scrapers 402 are evenly provided on both sides of the end face of the door leaf 4 along the height direction. The bottom end of the inclined scraper 402 is inclined towards the first through groove 5. During the process of controlling the door leaf 4 to move upward, the inclined scraper 402 will clean the silt or impurities inside the door groove 101, push the silt or impurities outward, reduce the resistance of the door leaf 4 to rise, so that the door leaf 4 can be opened.

[0040] like Figure 2 As shown, in a preferred embodiment, based on the above method, a limit rod 704 is vertically installed on both sides of the top of the baffle 7. The limit rod 704 passes through the inside of the spring 703 and extends to the top of the door leaf 4. The limit rod 704 is slidably connected to the door leaf 4. By using the limit rod 704, the spring 703 and the baffle 7 can be limited to ensure the vertical movement of the baffle 7.

[0041] like Figure 4 As shown, in a preferred embodiment, based on the above method, a filter screen 501 is provided between the inner sides of the first channel 5, and the outer side of the filter screen 501 is flush with the end face of the door leaf 4. By using the filter screen 501, impurities in the water can be filtered to prevent impurities from clogging the first channel 5.

[0042] like Figure 4 As shown, in a preferred embodiment, based on the above method, the front and rear ends of the door leaf 4 are evenly vertically provided with a guard bar 502, and the guard bar 502 is located at the front end of the filter screen 501. The use of the guard bar 502 can prevent large objects from impacting the filter screen 501 and protect the filter screen 501.

[0043] Example 3

[0044] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0045] With the gate fully closed, the gate leaf 4 is inserted into the bottom of the gate frame 1, and the baffle 7 moves down to the bottom of the slide groove 6. The first through groove 5 and the second through groove 701 are misaligned. At this time, the spring 703 is in a stretched state. When it is necessary to open the gate, the hoist 2 is activated to control the screw 3 to move upward. In the initial stage, the upward movement of the screw 3 only drives the baffle 7 to move upward. At the same time, the upward movement of the baffle 7 is also subject to the tension of the spring 703. The upward movement of the baffle 7 is more effortless and easier to open. After the second through groove 701 of the baffle 7 is connected to the first through groove 5, the gate is in a low-flow-rate open state. By using the filter screen 501, the water quality can be improved. The impurities are filtered to prevent them from clogging the first channel 5. The use of the baffle 502 can prevent large objects from impacting the filter screen 501 and protect the filter screen 501. When the baffle 7 moves to the top of the slide 6, the spring 703 returns to its original position, and the second channel 701 is completely aligned with the first channel 5. If the screw 3 moves upward again, it will simultaneously control the upward movement of the door leaf 4 and the baffle 7, increasing the opening range of the gate. During the upward movement of the door leaf 4, the inclined scraper 402 will clean the silt or impurities inside the door groove 101, push the silt or impurities outward, reduce the resistance of the door leaf 4 to rise, and facilitate the opening of the door leaf 4.

[0046] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
