Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, in particular to a box-type non-negative pressure water supply equipment with a self-cleaning function. Background Art

[0002] In current water supply practices, existing tank-type, non-negative-pressure water supply systems often experience scale deposits on the inner walls of their water tanks after long-term operation. Furthermore, these systems generally lack effective wall cleaning mechanisms. Over time, scale and other impurities accumulate on the inner walls of the water tanks, creating favorable conditions for bacterial growth and posing a serious threat to water supply hygiene and safety. Furthermore, these deposits can negatively impact the entire water supply system, such as causing blockages in water supply pipes and affecting the stability and reliability of the water supply.

[0003] Under existing technical conditions, cleaning the water tanks in tank-type, non-negative-pressure water supply systems presents numerous drawbacks. When cleaning the water tanks, the associated water supply system must be shut down. Cleaning personnel can only access the tanks through a pre-defined manhole. This cleaning method has significant drawbacks: Firstly, the entire cleaning process is extremely time-consuming and labor-intensive, requiring significant human resources. Secondly, due to the limitations of manual operation, the interior of the water tanks is often not thoroughly cleaned, making it difficult to achieve the required cleaning standards, which in turn negatively impacts water supply quality. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a box-type non-negative pressure water supply equipment with a self-cleaning function.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A box-type non-negative pressure water supply equipment with a self-cleaning function includes a box body and a cover body, an annular mounting groove is provided on the inner wall of the box, four arcuate bars are provided in the annular mounting groove, and the four arcuate bars are fixed to each other by connecting bolts, a limiting mechanism for limiting the four arcuate bars is provided in the annular mounting groove, a driving motor is provided in the annular mounting groove, and the driving motor is connected to the four arcuate bars through a rotating mechanism, a retaining ring is provided in the box body through a sealing mechanism, and the retaining ring is connected to one of the arcuate bars through a connecting mechanism, and a scraping strip in contact with the inner wall of the box is provided on the retaining ring.

[0007] Preferably, the limiting mechanism includes a limiting frame arranged in the annular mounting groove, and the limiting frame is installed in the annular mounting groove through limiting bolts.

[0008] Preferably, the rotating mechanism includes a gear mounted on the output shaft of the driving motor, and each of the four arc-shaped bars is provided with a rack corresponding to the gear.

[0009] Preferably, the sealing mechanism comprises an annular sealing strip mounted on the inner wall of the box body, and an annular sealing groove corresponding to the annular sealing strip is provided on the surface of the retaining ring facing the box body.

[0010] Preferably, the connection mechanism includes a connection bolt that is rotatably installed through the connection rod, and a threaded connection groove corresponding to the connection bolt is provided on the surface of the retaining ring facing the box body.

[0011] Preferably, an opening is provided on the outer wall of the box body, and the opening is communicated with the annular mounting groove and corresponds to the limiting frame.

[0012] Beneficial effects of the utility model:

[0013] 1. After the equipment starts the driving motor, the gear and rack can drive the arc bar to rotate, and then the retaining ring connected to the arc bar rotates. The scraper on the retaining ring can scrape off scale and other impurities on the inner wall of the box, effectively keeping the inside of the box clean, reducing the impact of impurity accumulation on the water quality, and reducing the possibility of equipment failure due to scale and other problems.

[0014] 2. The housing and cover can be easily assembled and disassembled using existing technology. The curved bars are connected by connecting bolts, and openings allow for easy access to the connecting bolts after removing the limiter bracket, releasing the curved bars. The retaining ring is connected to the curved bar by connecting bolts and can be easily disassembled. This design facilitates individual maintenance or replacement of each component, improving maintenance efficiency and reducing maintenance costs.

[0015] 3. Through reasonable structural design, after removing the relevant bolts and limit frames, the retaining ring, scraper strip and arc strip can be taken out in turn, which facilitates in-depth maintenance of these components and replacement of new parts to ensure long-term and stable operation of the equipment.

[0016] 4. The limit frame in the limiting mechanism is L-shaped and is installed in the annular mounting groove through the limit bolts. It can effectively prevent the arc strip from moving horizontally in the annular mounting groove, ensuring the stability of the arc strip position during equipment operation, thereby ensuring the reliable realization of the self-cleaning function.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-6

[0026] A box-type non-negative pressure water supply device with a self-cleaning function includes a box body 1 and a cover body 2. The box body 1 and the cover body 2 can be easily assembled and disassembled by any installation method in the prior art. Other equipment components are also provided on the box body 1 and the cover body 2 to form the box-type non-negative pressure water supply device. The specific equipment components are not described in detail in this solution. For details, please refer to the prior art.

[0027] An annular mounting groove 4 is provided on the inner wall of the box body 1, and four arc-shaped strips 8 are provided in the annular mounting groove 4. The four arc-shaped strips 8 are fixed to each other by connecting bolts 14. A limiting mechanism for limiting the four arc-shaped strips 8 is provided in the annular mounting groove 4. A driving motor 13 is provided in the annular mounting groove 4. The driving motor 13 is connected to the four arc-shaped strips 8 through a rotating mechanism. A retaining ring 5 is provided in the box body 1 through a sealing mechanism. The retaining ring 5 is connected to one of the arc-shaped strips 8 through a connecting mechanism. A scraper strip 7 in contact with the inner wall of the box body 1 is provided on the retaining ring 5.

[0028] The limiting mechanism includes a limiting frame 11 disposed within the annular mounting groove 4, which is mounted within the annular mounting groove 4 via limiting bolts 12. As shown in the figure, the limiting frame 11 is L-shaped. Because only the curved outer walls and bottom surfaces of the four curved strips 8 are in contact with the curved inner walls of the annular mounting groove 4 and the ground, the limiting frame 11 prevents the curved strips 8 from moving laterally within the annular mounting groove 4, that is, from moving away from the cover body 2, and prevents them from moving closer to the cover body 2.

[0029] The rotating mechanism includes a gear 10 mounted on the output shaft of the drive motor 13, and each of the four arc-shaped bars 8 is provided with a rack 9 corresponding to the gear 10. The arrangement of the gear 10 and the rack 9 can drive the four arc-shaped bars 8 to rotate with the help of the gear 10 and the rack 9 after the drive motor 13 is started.

[0030] The sealing mechanism includes an annular sealing strip mounted on the inner wall of the box body 1, and an annular sealing groove corresponding to the annular sealing strip is provided on the surface of the retaining ring 5 facing the box body 1. The annular sealing strip is in the annular sealing groove to ensure a sealing effect and prevent water from entering the annular mounting groove 4.

[0031] The connection mechanism includes a connecting bolt that is rotatably mounted on a connecting rod 6. The surface of the retaining ring 5 facing the box body 1 is provided with a threaded connection groove corresponding to the connecting bolt. The end of the connecting rod 6 is flush with the inner wall of the box body 1, and the connecting bolt provided on it enables the connection between the retaining ring 5 and one of the curved bars 8, as well as convenient disassembly between the two.

[0032] An opening 3 is provided on the outer wall of the box body 1, which is connected to the annular mounting groove 4 and corresponds to the limit frame 11. Through the opening 3, it is convenient to disassemble the limit frame 11. After the limit frame 11 is disassembled, the connecting bolts 14 connecting the two arc bars 8 can be disassembled.

[0033] When the utility model is used, after the driving motor 13 is started, it can drive the gear 10 to rotate, and the gear 10 can drive the four arcuate bars 8 to rotate with the help of the rack 9. The rotation of the arcuate bar 8 can cooperate with the connecting rod 6 and the connecting bolt to drive the retaining ring 5 to rotate. The scraper 7 on the retaining ring 5 rotates in the box body 1, and can scrape off impurities such as scale on the inner wall of the box body 1, thereby realizing self-cleaning operation.

[0034] In this solution, after the cover body 2 is opened and the limit bolt 12 is removed through the opening 3, the limit frame 11 can be removed and taken out, and then the connecting bolts 14 connecting the arc strips 8 can be removed to release the connection of the four arc strips 8, and the connecting bolts can be removed to release the connection of the retaining ring 5. First, the retaining ring 5 and the scraper strip 7 can be taken out through the box opening of the box body 1, and then the individual arc strip 8 can be moved so that it is close to the cover body 2 and staggered with the gear 10. Then, since the annular mounting groove 4 loses the obstruction of the retaining ring 5, one of the arc strips 8 can be taken out, and then the remaining arc strips 8 can be taken out.

[0035] At this point, the disassembly of the retaining ring 5, the scraper strip 7 and the curved strip 8 and other components has been completed. The convenient disassembly of the above components is not only convenient for maintenance thereof, but also convenient for replacement of multiple components.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
