Description

Technical Field

[0001] The invention relates to the field of cleaning technology, and in particular to an automatic cleaning device for a domestic water tank for secondary tap water supply and a use method thereof. Background Art

[0002] The service water pressure of the urban water supply network can generally only be supplied to the 5th or 6th floor. Therefore, residents above the 6th floor need to rely on the secondary water supply system to increase the water pressure to ensure the normal water use of residents in high-rise buildings. That is, when the water pressure of the municipal water supply pipeline cannot meet the water demand of residents in high-rise buildings, it needs to be stored and pressurized before being supplied to residents in high-rise buildings. This is usually achieved through a reservoir or water tank set on the roof. After the water is output from the water plant, it is first sent to the reservoir or water tank, and then pressurized to the residents' homes. During the use of the reservoir or water tank, due to oxidation and various impurities, certain impurities will accumulate inside the water tank or water reservoir. At present, the cleaning method for the reservoir and water tank is usually manual cleaning or automatic cleaning mechanism is set in the water tank or water reservoir. Compared with manual cleaning, the automatic cleaning mechanism is more convenient, and there is no need to leave a large amount of impurities in the water tank or clean it after a certain period of use.

[0003] Publication number CN218574520U discloses a tap water secondary water supply disinfection and cleaning device, which makes it easy to clean the inner wall of the water tank by making the brush movable, saving labor. By making the pump input clean water or disinfectant water into the movable shell, it is easy to clean and disinfect the inner wall of the water tank, thereby improving the cleaning efficiency.

[0004] Based on the existing technology, there are the following problems:

[0005] Existing automatic cleaning equipment for secondary water supply tanks of tap water usually arranges multiple rotatable nozzles inside the water tank and supplies water to the nozzles to clean the inside of the water tank through water flow. Although this method does not require staff to enter the water tank for cleaning, it avoids increasing the degree of secondary pollution of the water tank due to improper operation, and improves the cleaning efficiency. However, in order to ensure that the inside of the water tank is fully cleaned, it is usually necessary to set electronic devices for adjusting the angle of the nozzle in the water tank. The air in the water tank is humid, which can easily damage the electronic devices, such as short circuit, and the damaged electronic devices can easily cause pollution to the water tank, such as generating thick smoke or dropping impurities into the water tank, affecting the actual use of the water tank for cleaning. In addition, the nozzle adjustment angle is affected by the laying of water pipes, and there is a blind angle for adjustment. In order to solve the above problems, an automatic cleaning equipment and a use method of domestic water tank for secondary water supply of tap water are proposed. Summary of the invention

The baffles 2843 are all designed in a semi-annular shape so as to seal between the first rod body 27 and the mounting plate 29 when two baffles 2843 are spliced ​​into a complete ring. The baffle 2843 is located in the electric heating tube 283:

[0092] The mounting groove 2844 is opened at the end of one side where the baffle 2843 is close to each other, and the first electromagnet 2846 and the second electromagnet 2841 are fixedly provided inside the mounting groove 2844 respectively.

[0096] In a specific implementation, when the electric push rod 22 drives the first rod body 27 to move vertically to adjust the height of the water spray assembly 25, the electric push rod 22 drives the mounting seat 23 to move vertically. During this process, the mounting seat 23 drives the top of the rubber telescopic tube 281 to move, thereby extending the rubber telescopic tube 281. When the first rod body 27 moves to the top of the water tank 1, the rubber telescopic tube 281 seals the first rod body 27 to prevent the first rod body 27 from contacting the outside world and then entering the water tank 1 during the vertical movement, thereby reducing pollution to the water tank 1 and avoiding setting the electric push rod 22 inside the water tank 1.

[0097] The first rod 27, the mounting plate 29 and the water tank 1 are sealed by the mounting ring 282 and the sealing ring 2821 without affecting the movement of the first rod 27. The outer wall of the first rod 27 and the top of the mounting plate 29 are blocked by the blocking assembly 284 from the top of the mounting plate 29, thereby sealing the connection between the first rod 27 and the mounting plate 29, further improving the sealing effect.

[0098] When the blocking assembly 284 is specifically operated, when the electric push rod 22 drives the first rod body 27 to move, the first electromagnet 2846 and the second electromagnet 2841 are powered off to avoid affecting the vertical movement of the first rod body 27. When the first rod body 27 is completely moved, that is, after the cleaning is completed and the water spray assembly 25 is located at the upper end of the inner wall of the water tank 1, the first electromagnet 2846 and the second electromagnet 2841 are powered on to generate suction force on the side where the first electromagnet 2846 and the second electromagnet 2841 are close to each other, thereby driving the baffle 2843 to move closer to each other, so that the two semi-annular baffles 2843 are spliced ​​into a complete ring body, so as to block the first rod body 27 and the mounting plate 29.

[0099] The guide rod 2845 is inserted into the guide hole to limit the movement of the baffle 2843, so as to facilitate the splicing of the baffle 2843, and the movement of the baffle 2843 is limited by the slide groove 2842 and the slider to prevent the guide rod 2845 from being separated from the guide hole;

[0100] The electric heating tube 283 is used to dry the rubber telescopic tube 281 after it is contracted, so as to prevent the water brought out by the first rod body 27 from being retained in the rubber telescopic tube 281 for a long time and breeding bacteria, etc., so as to facilitate the long-term cleaning of the water tank 1. The temperature of the electric heating tube 283 is set according to actual conditions to avoid too high temperature affecting the use of the first electromagnet 2846 and the second electromagnet 2841.

[0101] The first servo motor 201 and other electronic components of the present invention are connected to an external power supply and a controller through wires for practical control and use. The above are all prior arts and will not be elaborated here.

[0102] The embodiment of the present invention also provides a method for using an automatic cleaning device for a domestic water tank 1 for secondary water supply of tap water, using an automatic cleaning device for a domestic water tank 1 for secondary water supply of tap water, the method comprising the following steps:

[0103] S1: Connect the external pipe to the water spray assembly 25 to supply water into the water spray assembly 25, so as to clean the inner wall of the water tank 1 through the water spray assembly 25. The first rod 27, the second rod 292 and the third rod 203 are all hollow, so that the external pipe can be laid along the inner wall of the second rod 292 and the third rod 203. The fluid slip ring 253 of the water spray assembly 25 can supply water to the water guide pipe 251, and the water guide pipe 251 and the external pipe can rotate relatively, so as to clean the inner wall of the water tank 1 comprehensively.

[0104] S2: When the water spray assembly 25 cleans the water tank 1, the height, horizontal rotation angle and vertical rotation angle of the water spray assembly 25 are adjusted respectively by the electric push rod 22, the lateral adjustment assembly 24 and the longitudinal adjustment assembly 20 to assist the water spray assembly 25 in cleaning the water tank 1, and the driving structures of the lateral adjustment assembly 24 and the longitudinal adjustment assembly 20, namely the first servo motor 201 and the second servo motor 241, are arranged on the top of the water tank 1, thereby avoiding the electrical mechanism being arranged in the water tank 1 and not affecting the adjustment angle of the nozzle 252;

[0105] S3: When adjusting the height of the water spray assembly 25, the first rod body 27 is moved to the position of the top of the water tank 1 through the sealing assembly 28 to seal, thereby limiting the entry of impurities into the water tank 1 from the connection between the first rod body 27 and the water tank 1, and facilitating the electric push rod 22 for adjusting the height of the water spray assembly 25 to be set at the top of the water tank 1.

[0106] The external pipe in step S1 is used to transport water and disinfectant into the water spray assembly 25 , that is, disinfectant or water can be transported successively into the water guide pipe 251 through the multi-way pipe to improve the cleaning effect of the water tank 1 .
