Description

Technical Field

[0001] This utility model relates to the field of water tank cleaning technology, specifically a rectangular secondary water supply tank cleaning device. Background Technology

[0002] Secondary water supply refers to the process by which units or individuals store and pressurize urban public water supply or self-built facility water supply, and then supply it to users or for their own use through pipelines. With the development of society and construction technology, there are more and more high-rise buildings. In order to ensure the normal water supply for high-rise residents, construction units will install water tanks on the roof. Since the water in high-rise buildings is secondary water supply, the cleanliness of the inside of the water tank is related to people's water safety, so it is necessary to clean the inside of the water tank regularly.

[0003] Currently, water tank cleaning methods are divided into manual cleaning and quick cleaning using devices. Since there are many water tanks in the community, manual cleaning is slow and labor-intensive, resulting in low efficiency in subsequent work. Therefore, cleaning devices are generally installed in the new water tanks in the community for cleaning. The cleaning device is soaked in water for a long time. Long-term soaking will cause the adhesive on the brush to soften, causing the bristles to fall off. At the same time, dyes, adhesives and other substances on the brush may dissolve into the water, causing water pollution. Utility Model Content

[0004] The purpose of this invention is to provide a rectangular secondary water supply tank cleaning device to solve the problem mentioned in the background art that current cleaning devices on the market cause water pollution when immersed in water for a long time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rectangular secondary water supply tank cleaning device, characterized in that it includes a brush that fits against the inner wall of the water supply tank, a cover plate located at the top of the water supply tank, movable blocks sliding around the cover plate, and a support rod rotatably connected to the movable blocks via a shaft, with a brush provided on the outer side of the support rod.

[0006] Preferably, a ladder is installed on the side of the water supply tank, and the water supply tank has a rectangular structure.

[0007] Preferably, a threaded rod is rotatably connected to the top of the cover plate, a limit plate is threadedly connected to the outside of the threaded rod, and a limit rod is installed on the top of the cover plate, the limit rod penetrating the interior of the limit plate.

[0008] Preferably, the cover plate has a sliding groove around its perimeter, and a movable block is inserted inside the sliding groove.

[0009] Preferably, the limiting plate has a square structure and is located above the slide groove.

[0010] Preferably, a push rod slides inside the movable block, with the top of the push rod fitting against the bottom of the limiting plate, the push rod passing through the inside of the sliding groove, and the length of the push rod being greater than the shortest distance from the brush to the limiting plate.

[0011] Preferably, a spring is installed between the side of the support rod near the push rod and the moving block, and a hydraulic cylinder is installed around the top of the cover plate, with the output end of the hydraulic cylinder fixed to the side of the moving block.

[0012] Preferably, a top cover is installed on the top of the cover plate, the top of the threaded rod protrudes out of the outer side of the top cover, a stepper motor is installed at the bottom of a support rod near the side of the ladder, and a support rod is installed at the output end of the stepper motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The hydraulic cylinder extends and retracts, causing the moving block to slide inside the groove. The bottom end of the limiting plate limits the top of the push rod, keeping the push rod stable. The push rod keeps the support rod and brush vertical. The brush moves back and forth, brushing the inner wall of the water supply tank. The spring force causes the brush and support rod to rotate upward, making the brush fit against the cover plate and separating the brush from the water. This prevents the brush from being immersed in water for a long time, protecting the brush and preventing the bristles from falling off due to softening of the adhesive. At the same time, the dyes, adhesives, and other substances on the brush will not dissolve in the water, increasing the service life of the brush, improving the water quality inside the water supply tank, and reducing the impact of water quality on human health.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 The present invention provides the following technical solution:

[0025] A rectangular secondary water supply tank cleaning device includes a brush 10 that fits against the inner wall of the water supply tank body 1. A cover plate 3 is located at the top of the water supply tank body 1. Movable blocks 5 slide around the cover plate 3. A support rod 9 is rotatably connected to the movable blocks 5 via a shaft. The brush 10 is provided on the outer side of the support rod 9. A threaded rod 7 is rotatably connected to the top of the cover plate 3. A limit plate 4 is threadedly connected to the outer side of the threaded rod 7. A limit rod 6 is installed on the top of the cover plate 3 and penetrates the interior of the limit plate 4.

[0026] Rotate the threaded rod 7 clockwise by hand. The rotation of the threaded rod 7 causes the limiting plate 4 to move downward. The downward movement of the limiting plate 4 pushes the push rod 12, causing the push rod 12 to move downward. When the lower end of the push rod 12 moves to contact the support rod 9 and the brush 10, the push rod 12 moves downward, causing the support rod 9 and the brush 10 to rotate downward until the threaded rod 7 can no longer be rotated. Then stop rotating the threaded rod 7. At this time, the bottom end of the limiting plate 4 moves to the top of the cover plate 3 and contacts each other. At this time, the support rod 9 and the brush 10 are pushed to a vertical position by the push rod 12, and the side of the brush 10 is in contact with the inner wall of the water supply tank 1.

[0027] A top cover 14 is installed on the top of the cover plate 3. The top of the threaded rod 7 protrudes out of the outside of the top cover 14. A stepper motor 15 is installed at the bottom of a support rod 9 near the side of the ladder 2. The output end of the stepper motor 15 is equipped with the support rod 9.

[0028] After the side brush 10 is kept vertical, the stepper motor 15 is started. The stepper motor 15 runs and causes the end support rod 9 to rotate downward until the stepper motor 15 can no longer run. At this time, the brush 10 on the support rod 9 is in contact with the bottom of the inside of the water supply tank 1.

[0029] A ladder 2 is installed on the side of the water supply tank 1, and the water supply tank 1 has a rectangular structure.

[0030] The ladder 2 facilitates the staff to climb up and down the water supply tank 1. The staff can climb over the cover plate 3 via the ladder 2 and then walk to the threaded rod 7.

[0031] The cover plate 3 has grooves 8 around its perimeter, and a movable block 5 is inserted inside the grooves 8. The limiting plate 4 is a square structure and is located above the grooves 8. A push rod 12 slides inside the movable block 5. The top of the push rod 12 is in contact with the bottom of the limiting plate 4. The push rod 12 passes through the grooves 8. The length of the push rod 12 is greater than the shortest distance from the brush 10 to the limiting plate 4. A hydraulic cylinder 13 is installed around the top of the cover plate 3. The output end of the hydraulic cylinder 13 is fixed to the side of the movable block 5.

[0032] Start the hydraulic cylinder 13. The operation of the hydraulic cylinder 13 causes the moving block 5 to slide inside the slide groove 8. The movement of the moving block 5 drives the push rod 12, the support rod 9 and the brush 10 to move synchronously. Since the limit plate 4 limits the upper end of the push rod 12, the height of the push rod 12 remains unchanged during the sliding process. Therefore, the support rod 9 and the brush 10 can be limited during the sliding process. The side brush 10 moves to brush the inner wall of the water supply tank 1 back and forth. The bottom brush 10 cleans the bottom of the water supply tank 1. When cleaning the inside of the water supply tank 1, water needs to be kept inside the water supply tank 1 for better cleaning.

[0033] A spring 11 is installed between the side of the support rod 9 near the push rod 12 and the moving block 5.

[0034] After cleaning, drain the water from the water tank 1. The horizontal support rod 9 and the vertical support rod 9 are then misaligned. The stepper motor 15 is restarted, causing the bottom support rod 9 to rotate from horizontal to vertical until it reaches a vertical position. The stepper motor 15 then stops driving. Next, the threaded rod 7 is manually rotated in the opposite direction. This reverse rotation causes the limiting plate 4 to move upwards, preventing it from contacting the upper end of the push rod 12. At this point, the spring 11... The elastic force causes the vertically positioned brush 10 and support rod 9 to rotate upwards, keeping them horizontally positioned. During the upward rotation, the brush 10 and support rod 9 push the push rod 12, causing it to move upwards until the brush 10 is in contact with the cover plate 3. Afterwards, clean water is filled into the water supply tank 1. The water depth inside the water supply tank 1 should be lower than that of the brush 10, separating the brush 10 from the water inside the water supply tank 1 to prevent the adhesive from softening due to prolonged soaking and to prevent water contamination.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
