Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cleaning mechanisms, and in particular relates to a gate cleaning mechanism for water conservancy projects. Background Technology
[0002] Hydraulic engineering gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures. Hydraulic engineering gates are installed on the openings of structures such as spillways, bank spillways, discharge holes, and hydraulic tunnels. They can control water levels, regulate flow, discharge floods or transport water, and can also be used for passing ships and logs, and for discharging silt, ice, and floating debris. Hydraulic engineering gates can be divided into working gates, maintenance gates, and emergency gates. Working gates can be opened and closed in flowing water. Maintenance gates are used for short-term water blocking when structures or working gates are under maintenance, and are generally opened and closed in still water. Emergency gates can be closed in flowing water and opened in still water. Emergency gates that need to be closed urgently within a limited time are called fast gates.
[0003] Because water contains silt, debris, aquatic organisms, algae, and pollutants, these substances adhere to the surface of hydraulic engineering gates after long-term use, leading to increased opening and closing resistance, decreased sealing performance, and structural corrosion. Therefore, we propose a gate cleaning mechanism for hydraulic engineering projects. Utility Model Content

[0036] Example 1: This example provides a gate cleaning mechanism for a water conservancy project, including: a frame 1, a gate body 2, and a lift 3. The outer surface of the gate body 2 is in sliding contact with the inner wall of the frame 1. The lift 3 is fixedly installed above the frame 1. The lifting screw inside the lift 3 is fixedly connected to the upper part of the gate body 2. The lift 3 provides power for the gate to move up and down, thereby driving the gate to open or close up and down.
[0037] A slide rail 4 is fixedly connected to one side of the frame 1. A slider 5 is slidably connected to the inner wall of the slide rail 4. A support seat 6 is fixedly connected to the outer surface of the slider 5. A groove 7 is opened on the inner side of the support seat 6. Two symmetrical push blocks 8 are slidably connected to the inner wall of the groove 7. Both push blocks 8 have an inclined angle. A scraper 9 is connected to the side of the two push blocks 8 outside the support seat 6. One end of one scraper 9 is in contact with the outer surface of the gate body 2. The movement of the scraper 9 is controlled by the movement position of the push block 8. The scraper 9 is scraped off the mud, sand, debris, aquatic organisms, algae and pollutants adhering to the gate body 2 by contacting the scraper 9 with the gate body 2.
[0038] A guide rod 10 is fixedly connected to the inner wall of the support base 6. A slot 11 is opened on the inner side of the push block 8. A cover plate 12 is fixedly connected to the side of the push block 8 inside the support base 6, and the cover plate 12 corresponds to the guide rod 10. The outer surface of the guide rod 10 is slidably connected to the inner wall of the push block 8. A spring 13 is sleeved on the outside of the guide rod 10. The slot 11 provides a space for the spring 13 and the guide rod 10. The support base 6 receives the supporting force of the guide rod 10 through the cover plate 12.
[0039] The inner wall of the chute 7 is slidably connected to a top block 14, and the top block 14 has an inclined angle. The side of the top block 14 with the inclined angle is slidably connected to the side of the push block 8 with the inclined angle. The upper surface of the top block 14 is fixedly connected to a push plate 15, and an electric push rod 16 is provided above the push plate 15.
[0040] The electric push rod 16 serves as the power source, providing power for the vertical movement of the top block 14, support base 6, and other components. The top block 14 and push block 8 contact each other at an inclined angle, facilitating mutual pushing and movement. The top block 14 can slide up and down on the inner wall of the slide groove 7, which provides space for its movement. When the top block 14 moves downward, it pushes out the push block 8 below, causing the scraper 9 below to contact the gate body 2. The scraper 9 removes the mud, debris, aquatic organisms, algae, and pollutants adhering to the gate body 2. When the top block 14 moves upward, it disengages from the push block 8 below. The spring 13 pushes the push block 8 and the scraper 9 into the groove 7. After the top block 14 moves upward, it pushes out the push block 8 above, so that the scraper 9 above contacts the gate body 2. The scraper 9 scrapes away the mud, debris, aquatic organisms, algae and pollutants adhering to the gate body 2. Through the repeated pushing of the top block 14, the scraper 9 contacts the gate body 2 both above and below the support base 6, scraping away the mud, debris, aquatic organisms, algae and pollutants adhering to the gate body 2.
[0041] Example 2: This example provides a gate cleaning mechanism for a water conservancy project. In addition to the technical solution of the above example, it also has the following technical features: a loading seat 17 is fixedly connected to one side of the frame 1, an electric push rod 16 is fixedly installed below the loading seat 17, and the output end of the electric push rod 16 is fixedly connected to the upper surface of the push plate 15.
[0042] The electric actuator 16 is supported by the mounting base 17, which makes the electric actuator 16 stable. The electric actuator 16 is multi-stage, and the multi-stage electric actuator 16 can have a longer extension length.
[0043] Example 3: This example provides a gate cleaning mechanism for a water conservancy project. In addition to the technical solution of the above example, it also has the following technical features: the number of slides 4 is two, and the two slides 4 are symmetrical.
[0044] The number of sliders 5 is the same as the number of slides 4. The slides 4 and sliders 5 provide support at both ends of the support base 6 to maintain the stability of the support base 6. A resistance plate is installed at the contact point between the sliders 5 and the slides 4. The resistance plate provides support for the sliders 5, the support base 6 and other components installed on the support base 6. When there is no external force pushing, the support base 6 is kept in a stationary state to prevent the support base 6 and other components from moving up and down.
[0045] Example 4: This example provides a gate cleaning mechanism for a water conservancy project. In addition to the technical solutions of the above examples, it also has the following technical features: the number of guide rods 10 is two sets, the number of guide rods 10 in each set is three, and the three guide rods 10 are arranged in an equidistant array. One end of the guide rod 10 located inside the slot 11 is fixedly connected to a support block 18.
[0046] The guide rod 10 provides support for the spring 13 and the push block 8, maintaining the smooth operation of the spring 13 and the push block 8. The two sets of guide rods 10 provide support at both ends of the push block 8, balancing the support force on the push block 8.
[0047] Example 5: This example provides a gate cleaning mechanism for a water conservancy project. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the spring 13 is in contact with one side of the support block 18, and the other end of the spring 13 is in contact with one side of the cover plate 12 located inside the slot 11.
[0048] The spring 13 provides power for the push block 8 to reset. When the push block 8 moves to the outside of the slide groove 7, the spring 13 is compressed. The compressed spring 13 accumulates elastic potential energy. After the top block 14 disengages from the push block 8, the spring 13 pushes the push block 8 to move to the inside of the slide groove 7, so that the push block 8 is reset.
[0049] Example 6: This example provides a gate cleaning mechanism for a water conservancy project. In addition to the technical solutions of the above examples, it also has the following technical features: a sliding sleeve 19 is fixedly connected to the upper surface of the support base 6, and the inner wall of the sliding sleeve 19 slides in contact with the outer surface of the push plate 15.
[0050] The sliding sleeve 19 provides support for the push plate 15 and maintains the stability of the sliding sleeve 19.
[0051] Example 7: This example provides a gate cleaning mechanism for a water conservancy project. In addition to the technical solutions of the above examples, it also has the following technical features: two sets of sliding rods 20 are fixedly connected to the inner wall of the support base 6, and the two sets of sliding rods 20 are symmetrical. Each set of sliding rods 20 has three rods, and the outer surface of the sliding rods 20 is slidably connected to the inner wall of the top block 14.
[0052] The slide bar 20 provides support to the top block 14, maintaining the stability of the top block 14 and enabling it to run smoothly.
[0053] Working principle: When it is necessary to clean the silt, debris, aquatic organisms, algae, and pollutants on the gate, the electric push rod 16 is first activated. After the electric push rod 16 is activated, it pushes the top block 14 to move position through the push plate 15. If the top block 14 moves downward, it pushes the lower push block 8 and scraper 9 out of the slide groove 7, so that the lower scraper 9 contacts the gate body 2. At the same time as the push block 8 moves, the spring 13 is compressed. The upper push block 8 then drives the scraper 9 to move into the slide groove 7. Subsequently, as the lower scraper 9 moves downward, the silt, debris, aquatic organisms, algae, and pollutants adhering to the gate surface are scraped off. When the electric push rod 16 moves the top block 14 upward, the lower spring 13 pushes the lower push block 8 and scraper 9 into the slide groove 7. The upper push block 8 moves out of the slide groove 7 under the push of the top block 14, while compressing the upper spring 13. Then the upper scraper 9 contacts the gate body 2 and scrapes the gate body 2 again. The upper and lower scrapers 9 repeatedly scrape and clean the gate body 2, removing the mud, sand, debris, aquatic organisms, algae and pollutants adhering to the gate surface. At the same time, in order to prevent water from corroding the components, the water conservancy project gate cleaning mechanism is made of a large amount of corrosion-resistant materials, which improves the service life of the water conservancy project gate cleaning mechanism.
