Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically to a gate cleaning device for water conservancy construction. Background Technology

[0002] In water conservancy projects, sluice gates are key facilities for controlling water flow. During use, the normal operation of the sluice gates and the regulation of water flow are often affected by the accumulation of silt or the accumulation of dirt on the inner wall of the sluice gate.

[0003] Currently, common methods for cleaning sluice gates mainly include manual retrieval and mechanical cleaning equipment. Manual retrieval suffers from low efficiency, high labor intensity, and poor safety, especially when the water flow is rapid or the amount of debris is large. Existing mechanical cleaning equipment mostly relies on electric drive devices, which have complex structures and require external power supplies, limiting their application in remote areas or field water conservancy projects. They also have problems such as high maintenance costs for waterproof motors and susceptibility of electronic components to water vapor corrosion. Utility Model Content

[0004] This utility model provides a gate cleaning device for water conservancy construction to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A gate cleaning device for water conservancy construction includes an installation mechanism, which includes a mounting frame with a screw threadedly connected to its interior, and a handle fixedly connected to one end of the screw; a hydrodynamic drive mechanism, which includes a first rotating shaft with a rotating cylinder fixedly connected to its surface and blades fixedly connected to its surface; and a scraping cleaning mechanism, which includes a second sprocket with a second rotating shaft fixedly connected to its interior and a support rod fixedly connected to its surface.

[0007] A further improvement of this utility model is that the installation mechanism also includes an anti-loosening screw, the surface of which is connected to the internal thread of the handle, and one end of which is in close contact with the surface of the mounting bracket.

[0008] A further improvement of this utility model is that: a top block is rotatably connected to the end of the screw away from the handle, a rubber pad is fixedly connected to one side of the top block, and one side of the rubber pad overlaps with the inner wall of the gate.

[0009] A further improvement of the present invention is that the hydrodynamic drive mechanism further includes a first sprocket, one side of which is fixedly connected to one end of a first rotating shaft, and the surface of the first rotating shaft is rotatably connected to the interior below the mounting frame.

[0010] A further improvement of this utility model is that: a chain is engaged with the surface of the first sprocket, and the inner wall of one end of the chain is engaged with the surface of the second sprocket.

[0011] A further improvement of this utility model is that the scraping and cleaning mechanism also includes a bottom scraper, and the surface of the second rotating shaft is rotatably connected to the interior of the lower end of the mounting bracket.

[0012] A further improvement of this utility model is that a bottom scraper is fixedly connected to the surface of the bottom scraper rod, and side scrapers are fixedly connected to the surfaces of both ends of the second rotating shaft.

[0013] A further improvement of this utility model is that: a side scraper is fixedly connected to one side of the side scraper, and a corner scraper is bolted to one side of the side scraper.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a gate cleaning device for water conservancy construction. Through a hydrodynamic drive mechanism, water flow impacts the blades, driving a sprocket to rotate. This, in turn, drives a cleaning scraper in a cyclical motion via chain transmission, achieving automatic cleaning of the gate's inner wall. Suitable for field water conservancy projects without external power supply, it reduces energy consumption and maintenance costs. Employing a purely mechanical transmission structure avoids the use of electronic modules and complex electrical control systems, minimizing damage from water vapor and sediment, and improving the device's reliability and lifespan. It can operate continuously under water flow, promptly removing various types of debris adhering to the gate's inner wall, making it easier to use. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] Example 1

[0024] like Figure 1-5 As shown, this utility model provides a gate cleaning device for water conservancy construction, including an installation mechanism, which includes a mounting frame 11, with a screw 12 threadedly connected inside the mounting frame 11, and a handle 13 fixedly connected to one end of the screw 12; a hydrodynamic drive mechanism, which includes a first rotating shaft 21, with a rotating cylinder 22 fixedly connected to the surface of the first rotating shaft 21, and blades 23 fixedly connected to the surface of the rotating cylinder 22; and a scraping and cleaning mechanism, which includes a second sprocket 31, with a second rotating shaft 32 fixedly connected inside the second sprocket 31, and a support rod 33 fixedly connected to the surface of the second rotating shaft 32.

[0025] In this embodiment, during installation, the operator rotates the handle 13 in the installation mechanism to drive the screw 12 to move along the internal thread of the mounting frame 11, so that the rubber pad 16 of the top block 15 at the end of the screw contacts and presses tightly against the inner wall of the gate. The friction force is used to complete the initial fixation. Then, the anti-loosening screw 14 passes through the screw hole of the handle and presses tightly against the surface of the mounting frame to form a mechanical limit to prevent the screw from rotating and loosening, ensuring that the device is stably installed under the impact of water flow. The high elasticity of the nitrile rubber material of the rubber pad can adapt to the uneven surface of the inner wall.

[0026] Example 2

[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the installation mechanism further includes an anti-loosening screw 14, the surface of the anti-loosening screw 14 is connected to the internal thread of the handle 13, one end of the anti-loosening screw 14 is tightly abutted against the surface of the mounting bracket 11, the end of the screw 12 away from the handle 13 is rotatably connected to a top block 15, one side of the top block 15 is fixedly connected to a rubber pad 16, one side of the rubber pad 16 overlaps with the inner wall of the gate, and the hydrodynamic drive mechanism further includes a first sprocket 24, one side of the first sprocket 24 is fixedly connected to one end of the first rotating shaft 21, and the surface of the first rotating shaft 21 is rotatably connected to the internal thread of the mounting bracket 11.

[0028] In this embodiment, when driven by hydrodynamics, the water flow impacts the blades 23 on the surface of the rotating cylinder 22, generating a tangential force that drives the rotating cylinder to rotate around the first rotating shaft 21. This causes the first sprocket 24 to mesh with the second sprocket 31 via the chain 26, transmitting the water flow power to the scraping and cleaning mechanism. During the scraping operation, the second sprocket is coaxially fixed with the second rotating shaft 32, and drives the bottom scraper 34 and the side scraper 36 to rotate via the support rod 33. The bottom scraper 35 on the bottom scraper sticks to the bottom of the gate to scrape off solid dirt such as mud and sand, while the corner scraper 38 sticks to the inner corner of the gate to remove flexible dirt such as aquatic plants.

[0029] Example 3

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the surface of the first sprocket 24 is engaged with a chain 26, the inner wall of one end of the chain 26 is engaged with the surface of the second sprocket 31, the scraping and cleaning mechanism also includes a bottom scraper 34, the surface of the second rotating shaft 32 is rotatably connected to the interior of the lower end of the mounting bracket 11, the surface of the bottom scraper 34 is fixedly connected with a bottom scraper 35, the surfaces of both ends of the second rotating shaft 32 are fixedly connected with side scrapers 36, one side of the side scraper 36 is fixedly connected with a side scraper 37, and one side of the side scraper 37 is bolted to a corner scraper 38.

[0031] In this embodiment, the rotation frequency of the second rotating shaft 32 is positively correlated with the water flow speed, forming a spiral cleaning trajectory that covers the bottom, side walls, and corner areas. The scraper is made of wear-resistant polyethylene with hardened edges. After cleaning, the dirt is discharged with the water flow. During maintenance, the position of the top block is finely adjusted by rotating the handle, and the corner scraper is replaced by loosening the side scraper bolts. This device does not require external power and realizes fully automatic cleaning of "water flow drive - chain transmission - multi-directional scraping", reducing cleaning costs and the frequency of manual intervention.

[0032] The working principle of the gate cleaning device used in water conservancy construction will be explained in detail below.

[0033] like Figure 1-5As shown, during installation, the operator rotates the handle 13 in the installation mechanism to drive the screw 12 to move along the internal thread of the mounting bracket 11, so that the rubber pad 16 of the top block 15 at the end of the screw contacts and presses tightly against the inner wall of the gate, using friction to complete the initial fixation. Then, the anti-loosening screw 14 passes through the screw hole of the handle and presses tightly against the surface of the mounting bracket, forming a mechanical limit to prevent the screw from rotating and loosening, ensuring that the device is stably installed under the impact of water flow. The high elasticity of the nitrile rubber material of the rubber pad can adapt to the uneven surface of the inner wall. When driven by water power, the water flow impacts the blades 23 on the surface of the rotating cylinder 22, generating a tangential component force to drive the rotating cylinder to rotate around the first rotating shaft 21, so that the first sprocket 24 engages with the second sprocket 31 through the chain 26 to transmit the water flow power to the scraping and cleaning mechanism. During the scraping operation... The second sprocket is coaxially fixed with the second rotating shaft 32. It drives the bottom scraper 34 and the side scraper 36 to rotate through the support rod 33. The bottom scraper 35 on the bottom scraper sticks to the bottom of the gate to scrape off solid dirt such as mud and sand. The corner scraper 38 sticks to the inner corner of the gate to remove flexible dirt such as aquatic plants. The rotation frequency of the second rotating shaft 32 is positively correlated with the water flow speed, forming a spiral cleaning trajectory that covers the bottom, side walls and corner areas. The scraper is made of wear-resistant polyethylene with hardened edges. After cleaning, the dirt is discharged with the water flow. During maintenance, the position of the top block is finely adjusted by rotating the handle and the corner scraper bolts are loosened to replace the corner scraper. This device does not require external power and realizes fully automatic cleaning of "water flow drive - chain drive - multi-directional scraping", reducing cleaning costs and the frequency of manual intervention.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
