Description

Technical Field

[0001] This invention relates to the technical field of cleaning equipment, and more specifically, to a water tank cleaning device and cleaning method. Background Technology

[0002] Domestic water tanks are essential in modern residential buildings, serving as crucial water storage devices to ensure a normal water supply. They provide a sufficient supply of tap water quickly enough to guarantee daily living needs even after the water supply is cut off. Domestic water tanks are typically installed on rooftops or in basement pump rooms to store drinking water. These tanks have relatively large capacities, ranging from 1 ton to 2000 tons, and are mostly made of stainless steel with internal support frames to ensure their strength. Currently, cleaning domestic water tanks is mostly done manually, which raises concerns about safety, hygiene, and time.

[0003] 1. Manual cleaning requires staff to enter the water tank, which can easily lead to safety hazards. Staff entering and leaving the water tank can also cause hygiene problems, and the cleaning time is relatively long.

[0004] 2. Automatic cleaning by machine: Due to the usage requirements of domestic water tanks, it is necessary to ensure that their internal environment meets the corresponding hygiene standards. If the cleaning machine contains electrical equipment or moving joint structures, the moving joints need lubrication, and the electrical equipment needs to be charged or connected to a power source, which will cause pollution to the internal environment of the water tank. Improper use of electrical equipment may increase safety hazards. Summary of the Invention

[0005] In view of this, and in order to solve the above problems, the present invention provides a water tank cleaning device, the specific technical solution of which is as follows:

[0006] On one hand, a water tank cleaning device includes:

[0007] The washing components, placed inside the water tank, include a permanent magnet and a silicone brush strip disposed on the outer surface of the permanent magnet;

[0008] An electromagnetic main unit includes a main unit base and an electromagnetic rotating head mounted on the main unit base;

[0009] The control component is electrically connected to the electromagnetic rotor;

[0010] After the electromagnetic rotor rotates, it drives the washing component to rotate, generating a non-polar magnetic repulsion effect, causing the washing component to suspend directly in front of the electromagnetic rotor. By adjusting the magnetic force and rotation speed of the electromagnetic rotor, the distance between the washing component and the electromagnetic rotor can be controlled. The washing component contacts the inner wall of the water tank to achieve the purpose of cleaning the water tank.

[0011] The aforementioned water tank cleaning device, after the electromagnetic rotor rotates, causes the washing component to rotate, generating a non-polar magnetic repulsion effect, which suspends the washing component directly in front of the electromagnetic rotor. The washing component is controlled without contact by the electromagnetic host, and its position inside the water tank is controlled by moving the electromagnetic host. The purpose of cleaning the water tank is achieved by the washing component contacting the inner wall of the water tank. The washing component only needs to enter the water tank for safety and reliability.

[0012] Furthermore, it also includes several magnetic pressure sensors disposed at the front end of the main unit, the magnetic pressure sensors being distributed in a ring around the circumference of the electromagnetic rotor; the magnetic pressure sensors are electrically connected to the control component; the front end of the magnetic pressure sensor is provided with a magnetic block attracted by the magnetic force of the permanent magnet, and a pressure deformation block for detecting the pressure on the magnetic block; the magnetic pressure sensor senses the force generated by the permanent magnet in the washing component on the magnetic block and converts the force into an electrical signal which is transmitted to the control component; the control component calculates the distance between the permanent magnet and the electromagnetic rotor based on the change in the magnitude of the force, and then adjusts the rotational speed and electromagnetic force of the electromagnetic rotor.

[0013] Furthermore, it also includes a telescopic component; the telescopic component includes a telescopic cylinder and a telescopic rod disposed within the telescopic cylinder, the telescopic cylinder being fixedly mounted on the main unit base, and the electromagnetic rotating head being disposed on the telescopic rod.

[0014] Furthermore, it also includes a chassis and a lifting component mounted on the chassis, the lifting component being used to drive the electromagnetic host to perform lifting movements.

[0015] Furthermore, it also includes a moving component mounted on the chassis; the moving component includes four sets of moving parts evenly distributed along the circumference of the chassis, and the moving parts include a moving motor and moving wheels that are drivenly connected to the moving motor.

[0016] Furthermore, the electromagnetic host also includes several cooling fans disposed on the host base.

[0017] Furthermore, the movable wheel is a Mecanum wheel.

[0018] Furthermore, the chassis is an aluminum alloy frame.

[0019] On the other hand, a water tank cleaning method, applied to a water tank cleaning device, includes the following steps:

[0020] Place the washing equipment into the water tank;

[0021] Place the electromagnetic main unit in front of the washing device and drive the electromagnetic rotor on the main unit base to rotate.

[0022] The distance between the scrubbing parts and the electromagnetic rotor can be adjusted by controlling the magnetic force and rotation speed of the electromagnetic rotor through the control components. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of the invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0037] On the one hand, such as Figure 1 As shown, a water tank cleaning device according to one embodiment of the present invention includes:

[0038] The washing component 1 is placed inside the water tank and includes a permanent magnet 11 and a silicone brush strip 12 disposed on the outer surface of the permanent magnet 11.

[0039] The electromagnetic host 2 includes a host base 21 and an electromagnetic rotating head 22 mounted on the host base 21;

[0040] Control component 3 is electrically connected to electromagnetic rotor 22;

[0041] After the electromagnetic rotor 22 rotates, it drives the scrubbing component 1 to rotate, generating a non-polar magnetic repulsion effect, causing the scrubbing component 1 to suspend directly in front of the electromagnetic rotor 22. By adjusting the magnetic force and rotation speed of the electromagnetic rotor 22, the distance between the scrubbing component 1 and the electromagnetic rotor 22 can be controlled. The scrubbing component 1 is in contact with the inner wall of the water tank to achieve the purpose of cleaning the water tank.

[0042] The aforementioned water tank cleaning device, after the electromagnetic rotor 22 rotates, causes the washing brush 1 to rotate, generating a non-polar magnetic repulsion effect, which makes the washing brush 1 suspend in front of the electromagnetic rotor 22. The electromagnetic host 2 controls the washing brush 1 without contact, and the position of the washing brush 1 in the water tank is controlled by moving the electromagnetic host 2. The purpose of cleaning the water tank is achieved by the washing brush 1 contacting the inner wall of the water tank. It is safe and reliable as long as the washing brush 1 enters the water tank.

[0043] In one specific embodiment, the water tank is a nickel-containing stainless steel tank, which is non-magnetic or weakly magnetic. Because adding nickel to stainless steel compounds helps enhance the protective properties of chromium, commonly known as 300 series stainless steel, the presence of nickel alters the physical structure of the stainless steel, removing or suppressing magnetism.

[0044] like Figure 1 and Figure 2As shown, in one embodiment, it also includes several magnetic pressure sensors 4 disposed at the front end of the main unit 21. The magnetic pressure sensors 4 are distributed in a ring around the circumference of the electromagnetic rotor 22. The magnetic pressure sensors 4 are electrically connected to the control component 3. The front end of the magnetic pressure sensor 4 is provided with a magnetic block that is attracted by the magnetic force of the permanent magnet 11, and a pressure deformation block that detects the pressure on the magnetic block. The magnetic pressure sensor 4 senses the force generated by the permanent magnet 11 on the magnetic block in the washing component 1 and converts the force into an electrical signal and transmits it to the control component 3. The control component 3 calculates the distance between the permanent magnet 11 and the electromagnetic rotor 22 according to the change in the magnitude of the force, and then adjusts the rotation speed and electromagnetic force of the electromagnetic rotor 22. Thus, the magnetic pressure sensor 4 senses the force exerted by the permanent magnet 11 on the magnetic block inside the washing component 1 and converts the force into an electrical signal, which is then transmitted to the control component 3. The control component 3 calculates the distance between the permanent magnet 11 and the electromagnetic rotor 22 based on the change in the magnitude of the force, and then adjusts the rotation speed and electromagnetic force of the electromagnetic rotor 22 to control the washing component 1 to move back and forth in the water tank and clean the inner wall of the water tank.

[0045] In one embodiment, a telescopic component is also included; the telescopic component includes a telescopic cylinder and a telescopic rod disposed within the telescopic cylinder. The telescopic cylinder is fixedly mounted on the main unit base 21, and the electromagnetic rotor 22 is disposed on the telescopic rod. Thus, by moving the telescopic component back and forth to adjust the extension position of the electromagnetic rotor 22, the distance requirement for the electromagnetic rotor 22 to generate a non-polar magnetic repulsion effect between it and the washing component 1 is met.

[0046] like Figure 1 and Figure 3 , Figure 4 As shown, in one embodiment, the system further includes a chassis 5 and a lifting component 6 mounted on the chassis 5. The lifting component 6 drives the electromagnetic host 2 to move up and down. Specifically, the lifting component 6 includes a lifting cylinder and a lifting rod mounted inside the lifting cylinder, with the host base 21 mounted on the lifting rod. Thus, by using the lifting component 6 to drive the electromagnetic host 2 to move up and down, the washing components 1 inside the water tank are controlled to move up and down, thereby cleaning the side walls of the water tank.

[0047] In one embodiment, a movable component 7 is also included, mounted on the chassis 5. The movable component 7 comprises four sets of movable elements 71 evenly distributed along the circumference of the chassis 5. Each movable element 71 includes a movable motor 72 and movable wheels 73 that are driven by the movable motor 72. Specifically, the rotation axes of the four sets of movable wheels 73 point towards the center of gravity of the chassis 5. Thus, by controlling the different movable elements 71 through the control component 3, the chassis 5 can perform forward, backward, and turning movements, satisfying the requirement of the washing component 1 to move the water tank according to the actual condition of the water tank's inner wall.

[0048] In one embodiment, the electromagnetic host 2 also includes a plurality of cooling fans 23 disposed on the host base 21. Thus, by using the cooling fans 23 to dissipate heat from the electromagnetic host 2 which operates for extended periods, the practicality of the water tank cleaning device can be further improved.

[0049] In one embodiment, the movable wheel 73 is a Mecanum wheel. A Mecanum wheel is an omnidirectional wheel that can move in all directions. It consists of a hub and rollers surrounding the hub. The generatrix of the rollers is approximated by a constant-velocity helix or an elliptical arc. When the wheel rotates around the hub axis, the outer envelope of each small roller is a cylindrical surface. The wheel can roll forward continuously and has the characteristics of omnidirectionality, flexibility, and stability, meeting the usage requirements.

[0050] In one embodiment, the chassis 5 is an aluminum alloy frame. This aluminum alloy frame offers advantages such as light weight and strong structure, and it does not react magnetically with the electromagnetic rotor 22, thus meeting the usage requirements.

[0051] On the other hand, a water tank cleaning method according to one embodiment of the present invention, applied to a water tank cleaning device, includes the following steps:

[0052] S1. Place the washing equipment into the water tank;

[0053] S2. Place the electromagnetic main unit in front of the washing device and drive the electromagnetic rotor on the main unit base to rotate.

[0054] S3. The magnetic force and rotation speed of the electromagnetic rotor are controlled by the control components, thereby adjusting the distance between the washing parts and the electromagnetic rotor.

[0055] In the above-described water tank cleaning method, the electromagnetic rotor rotates, causing the washing component to rotate and generating a non-polar magnetic repulsion effect, which suspends the washing component directly in front of the electromagnetic rotor. The washing component is controlled without contact by the electromagnetic host, and its position inside the water tank is controlled by moving the electromagnetic host. The washing component is cleaned by contacting the inner wall of the water tank.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
