Description

Technical Field

[0001] The present invention relates to the field of water supply, and in particular to a water supply device and a method thereof for a water plant used in a water system. Background Art

[0002] The non-negative pressure water supply unit is a commonly used water supply device in modern water systems. It can be directly connected to the municipal water supply network to provide secondary water supply for residents living on higher floors in the city, ensuring normal water pressure at high-rise water points.

[0003] The existing Chinese patent CN111576556B discloses an ultraviolet disinfection non-negative pressure water supply device, which uses a driving mechanism to make multiple groups of ultraviolet lamps rotate synchronously inside the water tank to disinfect the water at multiple angles, solving the problem that the irradiation position angle of the ultraviolet lamp inside the existing water tank cannot be adjusted, affecting the ultraviolet disinfection effect of the water. It is proposed that under the action of the filter net and the filter cover installed on the outside of the ultraviolet lamp, the adhesion of stains to the ultraviolet lamp can be reduced. However, if the stains are effectively blocked by the filter cover, the aperture of the filter cover is very small, and the stains in the water will be attached to the filter cover in large quantities. The filter cover will seriously block the ultraviolet rays emitted by the ultraviolet lamp, affecting the effect of ultraviolet disinfection and sterilization. For this reason, we propose a water supply device and method for water plants used in water systems. Summary of the invention

[0015] A method for using a water supply device of a water plant used in a water system, the method comprising the following steps:

[0016] S1. During the UV disinfection and sterilization stage, water is input from the water injection pipe and output from the water outlet pipe. When the water enters the water tank, the flow impact of the water can cause the impeller to trigger the transmission part, so that the four sets of UV lamps and protective covers rotate alternately. The UV rays emitted by the protective cover can rotate alternately on the inside of the water tank under the drive of the transmission part;

[0017] S2. During the scraping stage of the scale deposited on the protective cover, the gear ring drives the two sets of scraping rings to move up and down under the action of the transmission parts, and cooperates with the rotation of the protective cover to effectively scrape off the deposits on the surface of the protective cover;

[0018] S3. During the cleaning stage of the attachments accumulated on the surface or inside of the scraper ring, when the scraper ring moves downward, the top column 2 and the top column 1 can be moved down by the limiter.

[0019] S4. During the triggering stage of the auxiliary reset member, when the top pillars 1 and 2 enter the sealing seat, the air inside the sealing seat squeezes into the airbag and expands it. When the spring 1 rebounds under the action of the limit member, the expanded airbag can assist the spring 1 in rebounding under the squeeze of the water pressure, thereby reducing the rebound load of the spring 1.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention cooperates with the ultraviolet disinfection mechanism, the scraping mechanism and the cleaning mechanism. During the water transportation process, the impeller triggers the transmission part, so that the four groups of ultraviolet lamps can rotate and irradiate in a staggered manner inside the water tank. At the same time, the gear ring moves up and down on the outside of the reciprocating screw rod to drive the scraping ring to scrape off the attachments on the surface of the protective cover to avoid blocking the ultraviolet light. Each time the scraping ring moves to the lowest end, the top column can knock the scraping ring once under the action of the limit member, and the attachments accumulated on the surface of the scraping ring are detached.

[0040] See also Figure 7 In the figure, the stiffness of spring 2 36 is twice greater than the sum of the stiffness of tension spring 1 38 and tension spring 2 42 to ensure that after the plug plate 41 loses the restriction of the toggle rod 34, its bearing plate 40 can effectively retract into the interior of the limiting cavity 33.

[0041] See also Figure 7 In the figure, the upper end horizontal plane of the top column 27 is higher than the upper end horizontal plane of the toggle rod 34 and lower than the lower end horizontal plane of the bearing plate 40, ensuring that the top column 27 can effectively rebound and knock on the scraper ring 20.

[0042] A method for using a water supply device of a water plant used in a water system, the method comprising the following steps:

[0043] S1. During the UV disinfection and sterilization stage, water is input from the water injection pipe 2 and output from the water outlet pipe 3. When the water enters the water tank 1, the flow impact of the water can cause the impeller 5 to touch the transmission member 8, so that the four sets of UV lamps 21 and the protective cover 17 rotate alternately. The UV rays emitted by the protective cover 17 can rotate alternately and irradiate the inner side of the water tank 1 under the drive of the transmission member 8;

[0044] S2. In the scraping stage of the scale on the surface of the protective cover 17, the gear ring 18 drives the two sets of scraping rings 20 to move up and down under the action of the transmission member 8, and cooperates with the rotation of the protective cover 17 to effectively scrape off the attachments on the surface of the protective cover 17;

[0045] S3. During the cleaning stage of the attachments accumulated on the surface or inside of the scraper ring 20, when the scraper ring 20 moves downward, the top column 27 and the top column 1 26 can be moved downward by the stopper 11. After moving downward by a certain distance, the top column 1 26 and the top column 27 can be triggered by the stopper 11 to break away from the restriction of the scraper ring 20 and quickly reset. The top column 1 26 can knock on the scraper ring 20, and the vibration force generated by the knocking can make the attachments attached to the surface or inside of the scraper ring 20 fall off;

[0046] S4. During the triggering stage of the auxiliary reset member 12, when the top column 26 and the top column 27 enter the interior of the sealing seat 23, the air inside the sealing seat 23 squeezes into the interior of the airbag 32 and expands it. When the spring 28 rebounds under the action of the limit member 11, the expanded airbag 32 can assist the spring 28 to rebound under the squeeze of the water pressure, thereby reducing the rebound load of the spring 28.

[0047] It can ensure that stains will not form scale on the surface of the ultraviolet lamp and affect the working principle of ultraviolet disinfection: during the use of the water supply device, a large amount of water can be input into the water tank 1 from the water injection pipe 2 and output from the water outlet pipe 3, and the water can make the impeller 5 rotate during the flow, and the impeller 5 can drive the two groups of reciprocating screws 16 to rotate through the transmission belt 15. Due to the active fit between the scraping ring 20 and the protective cover 17, the gear ring 18 can drive the two groups of scraping rings 20 to move up and down. At the same time, through the active meshing of the gear 13 and the gear 2 14, the four groups of protective covers 17 and the ultraviolet lamp 21 can rotate alternately, and the scraping ring 20 can effectively scrape off the stains attached to the surface of the protective cover 17, ensuring that the stains will not block the ultraviolet light and affect the effect of ultraviolet disinfection and sterilization;

[0048] When the scraper ring 20 is about to move to the lowest end, the slider 25 can be pushed by the supporting plate 40 to make the top column 26 and the top column 27 move toward the inside of the sealing seat 23. When the top column 26 is about to completely extend into the inside of the sealing seat 23 during the movement, the sealing cover 24 can rotate the toggle rod 34 so that the toggle rod 34 no longer completely lifts the plug plate 41, and under the action of the tension spring 1 38, the plug plate 41 moves downward, and the supporting plate 40 retracts to the inside of the limiting cavity 33 under the action of the tension spring 22. At this time, the scraper ring 20 loses the restriction on the top column 26. Under the action of the spring 1 28, the top column 26 and the top column 27 are quickly reset, and the top column 27 can knock the scraper ring 20 once. The vibration force generated by the knocking can remove the stains attached to the inside or the upper and lower end surfaces of the scraper ring 20. It should be noted that the height of the limiting cavity 33 is less than the thickness of the sealing cover 24 to avoid water leakage.

[0049] Embodiment 2:

[0050] See also Figure 5 and Figure 6This embodiment further explains Example 1, an auxiliary reset member 12 is also installed on the outer side of the sealing seat 23, the auxiliary reset member 12 includes a stabilizing frame 31 fixedly installed on the inner side of the water tank 1, and a fixing pipe 29 is fixedly installed on the inner side of the stabilizing frame 31, an air pipe 30 is connected between the fixing pipe 29 and the sealing seat 23, and an air bag 32 is fixedly connected to the outer side of the fixing pipe 29.

[0051] In the present embodiment, when the top column 26 and the top column 27 extend into the interior of the sealing seat 23, the gas inside the sealing seat 23 can be displaced to expand the airbag 32. At this time, the expansion of the airbag 32 is due to the squeezing of the scraper ring 20, and the airbag 32 is freed from the restriction of the scraper ring 20 under the action of the limiter 11. When the spring 1 28 causes the top column 26 and the top column 27 to rebound and reset, the gas collected by the airbag 32 can be quickly filled into the interior of the sealing seat 23 through the air pipe 30 under the action of the water pressure inside the water tank 1, thereby assisting the rebound of the spring 1 28, reducing the resistance encountered by the spring 1 28 during the rebound process, and ensuring the service life of the spring 1 28.

[0052] Embodiment 3:

[0053] See also Figure 4 , Figure 5 and Figure 8 , implementation mode further describes other embodiments, the scraping mechanism 9 includes two groups of reciprocating screws 16 movably embedded in the inner side of the water tank 1, each group of reciprocating screws 16 is distributed between two groups of protective covers 17, the outer side of the reciprocating screw 16 is meshingly sleeved with a gear ring 18, and the left and right ends of the gear ring 18 are fixedly installed with corrugated strips 19, and the end of the corrugated strip 19 away from the gear ring 18 is fixedly installed with a scraping ring 20, and the scraping ring 20 is movably fitted with the protective cover 17, the reciprocating screw 16 and the upper end of the transmission shaft 6 are movably inserted into the water tank 1, and a transmission member 8 is installed between the two.

[0054] In this embodiment: through the action of the transmission member 8, the scraper ring 20 can move up and down in contact with the outer wall of the protective cover 17 to scrape off the material attached to the outside of the protective cover 17, wherein the corrugated strips 19 are in the shape of water corrugations, and the scraper ring 20 is in the shape of hollows, the purpose of which is to reduce the water resistance encountered by the scraper ring 20 and the corrugated strips 19 when they move following the gear ring 18.

5. A method for using the water supply device of a water plant used in the water system according to claim 4, characterized in that: The method comprises the following steps: S1. In the ultraviolet disinfection and sterilization stage, water is input from the water injection pipe (2) and output from the water outlet pipe (3). When the water enters the water tank (1), the flow impact force of the water causes the impeller (5) to touch the transmission member (8), so that the four sets of ultraviolet lamps (21) and the protective cover (17) rotate alternately. The ultraviolet light emitted by the protective cover (17) can rotate alternately and irradiate the inner side of the water tank (1) under the drive of the transmission member (8); S2. During the scraping stage of the scale deposited on the surface of the protective cover (17), the gear ring (18) drives the two sets of scraping rings (20) to move up and down reciprocatingly under the action of the transmission member (8), and cooperates with the rotation of the protective cover (17) to effectively scrape off the deposited matter on the surface of the protective cover (17); S3. In the cleaning stage of the attachments accumulated on the surface or inside of the scraper ring (20), when the scraper ring (20) moves downward, the top column (27) and the top column (26) are moved downward by the limiter (11). After moving downward a certain distance, the top column (26) and the top column (27) are triggered by the limiter (11) to break away from the restriction of the scraper ring (20) and quickly reset. The top column (26) strikes the scraper ring (20), and the vibration force generated by the striking causes the attachments attached to the surface or inside of the scraper ring (20) to break away; S4. During the triggering stage of the auxiliary reset member (12), when the top column 1 (26) and the top column 2 (27) enter the interior of the sealing seat (23), the air inside the sealing seat (23) squeezes into the interior of the airbag (32) and expands it. When the spring 1 (28) rebounds under the action of the limit member (11), the expanded airbag (32) assists the spring 1 (28) to rebound under the pressure of the water pressure, thereby reducing the rebound load of the spring 1 (28).
