Technical Field

[0001] This utility model relates to the technical field of water supply facility maintenance equipment, specifically a portable cleaning device for rooftop water tanks. Background Technology

[0002] Secondary water supply tanks are crucial facilities for ensuring residents' water supply, and regular cleaning is a necessary measure to prevent water pollution. Currently, traditional tank cleaning mainly relies on manual labor, which presents the following problems:

[0003] 1. Water outage required for cleaning: Water supply valves need to be shut off before cleaning, which will cause water outages for residents. This is especially true in older communities without secondary pressurization facilities, where the water supply restoration time is long and the rate of user complaints is high.

[0004] 2. Low efficiency: Cleaning a single water tank takes about 40 minutes and involves a lot of manual labor.

[0005] 3. There are blind spots in cleaning: Scale in dark places at the bottom of the water tank or in deeper areas is difficult to observe, which can easily lead to incomplete cleaning;

[0006] 4. Waste of water resources: Traditional cleaning requires emptying the water tank and rinsing repeatedly, consuming hundreds of liters of water per cycle.

[0007] Existing cleaning equipment is mostly single-function designed or relies on a fixed power supply, making it unsuitable for the complex working environment of rooftops. Furthermore, it lacks efficient filtration devices, hindering continuous water supply cleaning. Therefore, developing a portable cleaning device for rooftop water tanks that combines high-efficiency cleaning, no drainage required, and easy operation has become an urgent technical challenge. Utility Model Content

[0008] This utility model provides a portable cleaning device for rooftop water tanks. Through structural innovation and functional optimization, it effectively solves the problems of low cleaning efficiency, significant impact of water outages, and water waste associated with traditional water tank cleaning. It has important application value for promoting the intelligent upgrading of the water industry and ensuring water supply security.

[0009] A portable cleaning device for rooftop water tanks includes a telescopic operating rod, a cleaning actuator, a filter, a drain hose, an underwater camera, and a display control panel. The cleaning actuator includes a water pump body. The front end of the telescopic operating rod is connected to the water pump body via a quick-release interface, and the rear end has a handle and a detachable remote control switch for the pump body embedded in the handle. The detachable remote control switch is used to start and stop the water pump body. The water pump body is fitted with a filter or drain hose through a drain outlet. The underwater camera is integrated into the side of the water pump body and is connected to the display control panel on the handle via a camera connection cable. The display control panel is used to display the images transmitted by the underwater camera in real time and switch the viewing angle of the underwater camera.

[0010] Furthermore, the telescopic operating rod adopts an aluminum alloy segmented nested structure, and its length can be adjusted from 1.4 to 3 meters through radial locking bolts. The outside of the rod body is provided with a cable storage groove, and the inside hollow channel is used for the camera connection cable to pass through.

[0011] Furthermore, the cleaning execution end also includes a brush and a quick-connect assembly port; the brush is connected to the outer periphery of the water inlet of the water pump body by a thread, and a standardized quick-connect buckle is provided at the drain outlet for selectively connecting the water inlet of the filter device or the interface of the drain hose.

[0012] Furthermore, the standardized quick-connect buckle engages with the corresponding slot of the filter device or drain hose via a spring pin, and can be separated by pressing the unlock button during disassembly.

[0013] Furthermore, the filtration device includes a filter housing and a filter element assembly disposed within the filter housing. The filter housing has a filter inlet and a filter outlet at both ends, respectively. The inner end of the filter element assembly is connected to the filter outlet, and the outer end is sealed with a filter screen end cap.

[0020] It adopts a segmented nested structure of 1.4 to 3 meters aluminum alloy, and the length can be infinitely adjusted by locking bolts to adapt to water tanks of different sizes (diameter 1 to 5 meters). This solves the problem of insufficient operating radius of traditional tools, allowing workers to complete all-round cleaning without entering the water tank.

[0021] 2. The filtration device achieves cleaning without draining water.

[0022] The filter directly filters impurities in the water tank, and the purified water flows back to the tank, eliminating the need for a drainage-filling process and saving more than 90% of water. The filter and the drain hose can be switched via a quick-release buckle (replacement can be completed within 30 seconds) to meet complex water quality scenarios (such as drainage mode for high impurity water tanks and filtration mode for low impurity water tanks).

[0023] 3. Underwater cameras improve cleaning accuracy

[0024] It integrates an underwater camera and display control panel, which can monitor scale in dark / deep areas of the water tank in real time. With the rotatable display control panel, it solves the problem of blind spots for human vision and ensures that the water quality meets the standards 100% after cleaning.

[0025] 4. Wireless remote control and power bank enhance portability

[0026] It adopts 2.4G wireless remote control (50-meter range) and 20000mAh outdoor power bank 9, freeing it from the constraints of fixed power supply. A single charge supports continuous operation for ≥4 hours, adapting to rooftop environments without power supply and improving equipment mobility.

[0027] 5. Dual-mode cleaning improves efficiency and applicability.

[0028] In filtration mode, the cleaning time for a single water tank is reduced to 10 minutes (compared to 40 minutes in the traditional mode), improving efficiency by 300%; no water outages are required, avoiding water interruptions for residents and significantly improving user satisfaction; the equipment is compatible with 70% of rooftop water tank types, making it widely applicable.
