Description

Technical Field

[0001] This utility model relates to the field of water tank disinfection technology, specifically a disinfection device for high-rise secondary water supply tanks. Background Technology

[0002] Due to limitations in urban water supply pressure (typically only covering buildings up to 6 stories), high-rise residential buildings exceeding 6 stories require pressurized water supply through secondary water supply facilities (such as water tanks and pumps). Water tanks, storing static water for extended periods, are prone to microbial growth, sediment buildup, and scale buildup. Furthermore, issues such as pipe coating peeling and external contaminant intrusion further threaten water quality. Regular disinfection is a core measure to ensure the hygiene and safety of secondary water supply. Relevant regulations require that high-rise water tanks undergo direct air contact cleaning and disinfection at least twice a year. Disinfection effectively kills pathogenic microorganisms, controls biofilm formation, and reduces the impact of disinfectant residues on water quality.

[0003] The commonly used disinfection process involves first manually scraping away silt and debris from the bottom of the water tank, followed by rinsing with a high-pressure water gun, and finally treating with chemical disinfectants. In actual operation, high-rise water tanks contain numerous horizontal and vertical pipes that directly obstruct worker movement. Workers must frequently maneuver around or adjust their posture to avoid support poles. While longer cleaning poles or water guns can be used, the increased length leads to increased weight, increasing workload, reducing efficiency, and making it easy to miss blind spots. Furthermore, because disinfectants are used, workers must wear protective clothing. However, traditional protective clothing generally has poor fit, and the torso area is prone to expansion due to gas ingress, further restricting limb movement. Summary of the Invention

[0004] The purpose of this invention is to provide a disinfection device for high-rise secondary water supply tanks to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides a disinfection device for a high-rise secondary water supply tank, comprising a backpack vest, a water gun, and a rotatable connecting structure connecting the two; the rotatable connecting structure includes a rotating wheel, a hook, a hanging ring, and a retractable belt; the rotating wheel is installed at the rear of the water gun, and a hook is provided on its outer side; one end of the retractable belt is fixed to the backpack vest, and the hanging ring is provided on the retractable belt, with the hook and hanging ring being detachably connected.

[0006] Furthermore, the rotating wheel is a bearing, with the inner ring welded to the rear of the water gun and the outer ring welded and fixed with a hook. One end of the retractable strap is fixed to the vest, and the other end passes through the hanging ring and is folded over to be connected to the other side of the lower end of the vest via Velcro, buckle or other common structures.

[0007] Furthermore, the water gun includes a rear section, several intermediate sections, and a front multi-functional section. The intermediate sections are detachably connected to the rear and front sections via a threaded structure.

[0008] Furthermore, the front multi-functional section includes a flat nozzle and a scraping part. The scraping part includes a scraping head and a connecting support rod. The scraping head is fixed to the outer wall of the front multi-functional section through the connecting support rod.

[0009] Furthermore, the scraping head is a flat blade-shaped mechanism or a friction block with abrasive cloth, and its front end is in front of the flat nozzle along the length of the water gun. Furthermore, a switch valve is installed at the rear of the water gun.

[0010] Furthermore, a handle is provided at the rear of the water gun. This invention features a flat nozzle and scraping section on the front of the high-pressure water gun, eliminating the need to switch tools between physical cleaning and water rinsing. This improves cleaning coverage and effectively addresses challenges such as confined space within the water tank and operational inconvenience. The multi-section design allows for easy increases in water gun length, while the rear section includes a handle and a rotatable connector that connects to a vest, providing a third stable support point for the worker. This effectively distributes the workload, reducing labor intensity and extending the effective working radius while minimizing the need for frequent crossing of the water tank support rods. The vest also features an adjustable tightening mechanism for a more snug fit, enhancing operational safety. Attached Figure Description

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.

[0016] As attached Figure 1-4As shown, the high-rise secondary water supply tank disinfection device disclosed in this utility model includes a backpack vest 1, a high-pressure water gun 2, and a rotatable connecting structure 3 connecting the two.

[0017] The backpack vest 1 is made of lightweight material and has multiple openings on its surface to reduce the stuffiness that the vest may cause while tightening the protective clothing. The lower part of the backpack vest 1 is connected to one end of the rotatable connecting structure 3. As attached Figure 1 , 2 As shown, the high-pressure water gun 2 adopts a split design, including a rear section 21, several intermediate sections 22, and a front multi-functional section 23. The intermediate sections 22 are detachably connected to the rear section 21 and the front section 23 through a threaded structure. The length of the water gun can be adjusted by changing the number of intermediate sections 22 to adapt to the operational needs of water tanks of different depths.

[0018] As attached Figure 3 As shown, the front multi-functional section 23 includes a flat nozzle 231 and a scraping part 232. The flat nozzle 231 is used to expand the high-pressure water flow and compress it into a strip shape, thereby expanding the water flow coverage area. The scraping part 232 includes a scraping head 2321 and a connecting support rod 2322. The scraping head is fixed to the outer wall of the front multi-functional section 23 by the connecting support rod. The scraper head 2321 is a flat blade-shaped mechanism or a friction block with abrasive cloth, which can be selected according to the local water quality and the degree of pollution in the water tank, and is used to scrape or rub stubborn dirt on the inner wall of the water tank. As attached Figure 4 As shown, the rotatable connection structure 3 includes a rotating wheel 31, a hook 32, a hanging ring 33, and a retractable strap 34.
