[0002] The non-negative pressure water supply equipment is a new type of water supply equipment, which directly superimposes water supply on the basis of municipal pipe network pressure, can effectively utilize the original pressure of the municipal pipe network, and avoids water quality pollution and other problems caused by water storage in the traditional water supply mode.

The cleaning device includes a device base, a first rotating shaft movably connected to the inside of the water tank, a connecting element connected to the first rotating shaft, a scraper element connected to the connecting element, a second rotating shaft connected to the device base, a connecting rod connected to the second rotating shaft, a magnetic attraction element connected to the connecting rod, and a first rotating motor for driving the second rotating shaft to rotate. The scraper element maintains a contact state with the inner wall of the water tank. The magnetic attraction element and the scraper element can be attracted to each other. The water tank is provided with a drain port, a water suction pipe connected to the drain port, and a water suction pump connected to the water suction pipe. The controller is electrically connected to the water suction pump and the first rotating motor.
[0004] For the related technology in the above, the inventors found that the following defects exist: the above-mentioned scheme drives the first sliding base and the second sliding base to move towards each other by controlling the first driving motor and the second driving motor. The water in the water tank will form a vortex due to the different rotation directions and movement directions of the two scrapers. Impurities will be attracted into the vortex. Since the central axis of the drain port coincides with the center position of the water tank, and the center position of the vortex is also at the center position of the water tank, it can be ensured that the impurities scraped by the scraper element can be quickly discharged from the drain port. However, this device cannot be designed in a modular manner, and the various functional modules cannot be easily disassembled and replaced. When the water pump fails, maintenance personnel have difficulty in removing the faulty water pump module from the equipment for maintenance or replacing a new water pump module, and a large-scale disassembly of the entire equipment is required, greatly increasing the maintenance time.

[0012] Optionally, the outer surface of each connecting rod is sleeved with a spring, the bottom end of each spring is fixedly connected with the corresponding plug, and the other end is fixedly connected with the corresponding connecting frame.
[0013] In summary, the application has the following beneficial technical effects:
[0014] This utility model comprises a base, a pump, a first connecting pipe, a water inlet pipe, a second connecting pipe, a connecting pipe, a fixed pipe, a vacuum eliminator, and a connecting head.

By pulling the connecting rod, the corresponding insert block slides vertically upward along the corresponding connecting frame, compressing the spring. Then, the connecting head is vertically inserted into the fixing groove and rotated until the spring, under its rebound force, pushes the corresponding connecting block into the fixing groove. Once the connecting block is inserted into the fixing groove, the connecting head is quickly fixed. Thus, this device achieves the effect of quickly assembling and disassembling the connecting head through the insert block and connecting block. Attached Figure Description
