Description

Technical Field

[0001] This utility model relates to the field of water conservancy channel filtration technology, specifically to a water conservancy channel filtration device. Background Technology

[0002] During water conveyance in irrigation canals, the water often carries impurities such as weeds, silt, and dead branches. Without filtration, these impurities can easily clog the canals, wear down water conveyance equipment, or affect the water quality for subsequent agricultural irrigation and industrial use. Therefore, filtration devices are necessary to purify the water flow. Existing irrigation canal filtration devices typically consist of a basic frame and a filter screen. In use, the device is placed directly in the canal or installed using a simple fixing structure. The filter screen separates impurities from the water flow, achieving initial filtration.

[0003] However, existing filtration devices have several shortcomings: First, they lack an effective water flow guiding structure, causing water to tend to flow in a dispersed manner within the channel. Some water carrying impurities may bypass the filter screen and pass directly through, resulting in incomplete impurity interception. The filtered water quality is insufficient to meet subsequent water conservancy needs and cannot provide clean water for agricultural irrigation, industrial water use, etc. Second, the device's installation structure is fixed, making it impossible to flexibly adjust the installation position according to the depth of different water conservancy channels. When the channel depth and device height do not match, the bottom of the device may not be in close contact with the bottom of the channel. This not only makes it prone to displacement and shaking under the impact of water flow but also allows impurities to pass through the gap between the bottom of the device and the channel, further reducing the filtration effect. It also limits the application of the device in water conservancy channels of different specifications, resulting in poor versatility and adaptability. Third, after impurities accumulate on the filter screen surface, the device needs to be manually disassembled for cleaning, which is cumbersome and labor-intensive. If cleaning is not done in time, it can also cause filter screen blockage, affecting water flow efficiency and preventing the filtration function from functioning continuously and stably. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a water conservancy channel filtration device that solves the problems of incomplete filtration, poor adaptability and inconvenient cleaning of existing devices, improves filtration effect and usage flexibility, and reduces maintenance costs.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a water conservancy channel filtration device, including an installation frame, a filter screen, a guide plate, a sliding member, a connecting rod, and a counterweight. The filter screen is installed on the installation frame, the symmetrically arranged guide plates are fixed to the side of the installation frame, the symmetrically arranged sliding members are slidably connected to the installation frame, the connecting rod is installed between the symmetrically arranged sliding members, and the symmetrically arranged counterweight is placed inside the installation frame. It also includes a cleaning component and a driving component. The cleaning component is used to clean impurities on the filter screen, and the driving component is used to drive the cleaning component to automatically clean the filter screen.

[0006] More preferably, the deflector is inclined.

[0007] More preferably, the counterweight has a groove for easy handling.

[0008] More preferably, the cleaning assembly includes a collection frame, a handle, and a cleaning roller. The collection frame is slidably connected to the mounting frame, the handle is fixed to the top of the collection frame, and the cleaning roller is rotatably connected to the collection frame, with the cleaning roller in contact with the filter screen.

[0009] More preferably, the drive assembly includes a worm, a worm wheel, a winding roller, a nylon line, a guide roller, and a hook. The worm is rotatably connected to the upper part of the mounting frame, the winding roller is rotatably connected to the upper part of the mounting frame, the worm wheel is keyed to the winding roller, the worm wheel meshes with the worm, the nylon line is wound around the winding roller, the guide roller is rotatably connected to the upper part of the mounting frame located in front of the winding roller, and the hook is connected to the end of the nylon line, hooking the handle.

[0010] More preferably, guide rollers are used to guide the nylon thread.

[0011] Compared with the prior art, the advantages of this utility model are: This utility model can guide the water flow and impurities to the filter screen through the inclined guide plate, and together with the filter screen, it can effectively intercept and filter the impurities in the water flow, improve the water purification effect, and provide a cleaner water source for subsequent water conservancy use; The sliding part can slide along the mounting frame, and in cooperation with the connecting rod, it can flexibly adjust the installation position of the device according to the actual depth of the water channel, ensuring that the bottom of the mounting frame is in close contact with the bottom of the water channel, adapting to water conservancy channels of different specifications, and enhancing the versatility and adaptability of the device.

[0012] The counterweight inside the mounting frame increases the overall stability of the device by its own weight, preventing the device from floating or shifting due to water flow impact. This ensures that the device can continuously and stably perform its filtering function in a water flow environment. In addition, the grooves on the counterweight make it easy for staff to pick up and adjust or replace the counterweight later.

[0013] Equipped with a cleaning component and a drive component, the filter screen can be cleaned without disassembling the device. Rotating the worm gear drives the cleaning roller to scrape off impurities from the filter screen surface, while the collection frame collects the scraped impurities. This reduces the workload and operational difficulty of manual cleaning, thereby lowering labor costs. The cleaning component can promptly remove accumulated impurities from the filter screen surface, preventing impurities from clogging the filter screen and affecting water flow efficiency, ensuring smooth water flow, maintaining a continuous and stable filtration efficiency, and ensuring the normal operation of the water conveyance and filtration functions of the water conservancy channel.

[0014] During the cleaning process, the cleaning roller contacts the filter screen and rolls to scrape away impurities without causing hard damage to the filter screen. This effectively extends the service life of the filter screen, reduces the frequency of filter screen replacement, lowers the cost of using and maintaining the device, and ensures the stability of the filtration effect, preventing filtration failure due to filter screen damage.

[0024] Example: As shown in the attached drawings, a water conservancy channel filtration device includes a mounting frame 1, a filter screen 2, a guide plate 3, a sliding member 4, a connecting rod 5, and a counterweight 6. The filter screen 2 is mounted on the mounting frame 1. The symmetrically arranged guide plates 3 are fixed to the sides of the mounting frame 1. The guide plates 3 are inclined to guide impurities and water in the channel, ensuring that impurities flow through the filter screen 2. The symmetrically arranged sliding members 4 are slidably connected to the mounting frame 1. The connecting rod 5 is installed between the symmetrically arranged sliding members 4. The sliding members 4 and the connecting rod 5 cooperate to adjust the flow according to the water level. The entire filter device is installed to the depth of the channel, so that the bottom of the mounting frame 1 can contact the bottom of the channel. The sliding part 4 is used to install the mounting frame 1 in the channel. The symmetrically arranged counterweights 6 are placed in the mounting frame 1. The counterweights 6 have grooves for easy handling. The counterweights 6 are used to increase the weight of the mounting frame 1 and prevent the mounting frame 1 from floating due to the impact of water. It also includes a cleaning component and a driving component. The cleaning component is used to clean the impurities on the filter screen 2, and the driving component is used to drive the cleaning component to automatically clean the filter screen 2.

[0025] In this embodiment, the cleaning component specifically includes a collection frame 7, a handle 8, and a cleaning roller 9. The collection frame 7 is slidably connected to the mounting frame 1, the handle 8 is fixed to the top of the collection frame 7, and the cleaning roller 9 is rotatably connected to the collection frame 7. The cleaning roller 9 contacts the filter screen 2 to clean the impurities on the filter screen 2, and the collection frame 7 collects the cleaned impurities. Furthermore, the drive assembly includes a worm gear 10, a worm wheel 11, a winding roller 12, a nylon line 13, a guide roller 14, and a hook 15. The worm gear 10 is rotatably connected to the upper part of the mounting frame 1, the winding roller 12 is rotatably connected to the upper part of the mounting frame 1, the worm wheel 11 is keyed to the winding roller 12 and meshes with the worm gear 10, the nylon line 13 is wound around the winding roller 12, the guide roller 14 is rotatably connected to the upper part of the mounting frame 1 and located in front of the winding roller 12, the guide roller 14 is used to guide the nylon line 13, and the hook 15 is connected to the end of the nylon line 13 and hooks the handle 8.

[0026] As water flows through the channel, the inclined guide plate 3 directs both the water and impurities towards the filter screen 2. The filter screen 2 intercepts and filters the impurities in the water, achieving initial water purification. The sliding component 4 can slide along the mounting frame 1, and in conjunction with the connecting rod 5, it can adjust the installation position of the device according to the depth of the channel, ensuring that the bottom of the mounting frame 1 is in close contact with the bottom of the channel. At the same time, the counterweight 6 inside the mounting frame 1 increases the stability of the device through its own weight, preventing the device from floating due to water flow impact. The groove on the counterweight 6 facilitates subsequent removal and adjustment.

[0027] When a large amount of impurities adhere to the surface of filter screen 2, the drive assembly activates, driving the cleaning assembly to operate. Rotating the worm gear 10 causes the worm wheel 11, meshing with the worm gear 10, to rotate, which in turn drives the keyed winding roller 12 to rotate. During the rotation of the winding roller 12, the nylon thread 13 is wound up. The guide roller 14 guides the nylon thread 13, preventing it from becoming entangled or misaligned. The nylon thread 13 pulls the handle 8 at the top of the collection frame 7 via the hook 15 at its end, causing the collection frame 7 to slide along the mounting frame 1. The cleaning roller 9, rotatably connected to the collection frame 7, remains in contact with the filter screen 2. As the collection frame 7 moves, the cleaning roller 9 rolls, scraping away impurities from the surface of the filter screen 2. The scraped impurities fall directly into the collection frame 7 for collection.

[0028] This automatic cleaning method cleans the filter screen 2 without disassembling the device, reducing manual cleaning workload and preventing impurities from clogging the filter screen 2. This ensures smooth water flow and maintains the continuous and stable filtration efficiency of the filtration device. Furthermore, the tight fit of all components prevents damage to the filter screen 2 during cleaning, extending its lifespan and ensuring the stability of the filtered water quality.

[0029] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
