Description

Technical Field

[0002] Generally speaking, structures are artificial structures that do not have, contain, or provide human habitation functions, such as water towers, pools, filtration tanks, clarifiers, and biogas tanks. Artificial structures that generally have, contain, or provide human habitation functions are called buildings. These structures will accumulate dirt and dust over long periods of use or storage, requiring manual cleaning and maintenance.

[0003] The existing integrated technology system for cleaning, spraying and anti-corrosion of the inner and outer walls of swimming pool structures only cleans and sprays the inner and outer walls of the structure. When encountering obstacles, it will choose to turn or try to bypass them, resulting in the bypassed areas not being worked, reducing the working area that can be covered by the equipment during one operation. For this reason, we propose an integrated technology system for cleaning, spraying and anti-corrosion of the inner and outer walls of the structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The lifting mechanism that lifts up and down is that lifting device is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that lifts up and down is installed in the lifting position, and the lifting mechanism that The device moves via the electric wheel at the bottom of the second electric stretch rod. When encountering an obstacle, the push plate is squeezed backward, and the spring applies force to the pressure sensor, activating the pressure sensor and controlling the extension of the second electric stretch rod, causing the base to move upward, thereby freeing up space for the device to pass over the obstacle. At the same time, the first electric stretch rod is controlled to retract, causing the top plate to move downward, driving the multiple structures connected to the top plate to move downward together, so that the working coverage area of ​​the high-pressure nozzle and spray plate remains unchanged, and it can pass over the obstacle without missing the wall. When the obstacle is passed, the spring supports the push plate to return to its original position, and the pressure sensor loses pressure and automatically closes, stopping the extension of the second electric stretch rod and the retraction of the first electric stretch rod. After one minute, it automatically returns to the original starting state. If the obstacle encountered is too high to be passed or hits the wall, the pressure sensor will be activated for a long time. When the pressure sensor activation time reaches one minute, it is determined that it cannot be passed and has encountered a wall. The electric wheel is automatically controlled to steer the device to avoid it, preventing the device from being stuck in a fixed position and moving.

[0021] Second, the present invention, when the pressure sensor goes out within one minute after being activated, it is determined that an obstacle is being crossed, and the third electric stretching rod is started to extend, so that the bottom plate moves downward, and the third motor and the electric water gate are started. The obstacles at the bottom are cleaned by rotating the brush with the third rotating shaft, and the water in the water tank is sprayed onto the brush through the second water pipe through the water spray ring under the third connecting plate. On the one hand, it can wet the brush, and on the other hand, it can wash away some dirt and dust adhering to the brush through the water flow, thereby facilitating the cleaning of the brush.

[0022] Third, the present invention starts the hot air blower, transmits the hot air into the blowing plate through the air duct, and blows the hot air onto the inner and outer walls through the enlarged opening. On the one hand, it can accelerate the evaporation rate of the residual moisture on the inner and outer walls, which is convenient for the adhesion of the sprayed paint to the inner and outer walls. On the other hand, it can heat the anti-corrosion paint sprayed on the inner and outer walls to accelerate the curing of the paint. The screen in the screen frame at the output port of the blowing plate can prevent small-volume debris from being stirred into the blowing plate when flushing with high-pressure water or blowing hot air. The fixation of the first connecting plate and the limiter can prevent the air duct from shaking during the hot air transmission, which makes its connection with the blowing plate unstable.

[0058] Example 4

[0059] An embodiment of an integrated technical system for cleaning, spraying and anti-corrosion of the inner and outer walls of a structure.

[0060] Place the device in a suitable pool to be treated, with the top of the device above the top of the pool to be treated.

[0061] Check the equipment: Check whether the water storage tank 102 and the clean water and anti-corrosion paint in the material storage box 105 in the equipment are full. The equipment includes an obstacle detection module, an information recording module, a cleaning module, a spray anti-corrosion module, a moving module and a storage module.

[0062] Equipment operation: Start the equipment, move it in the pool through the mobile module, and use the cleaning module to pre-treat and clean the inner and outer walls of the swimming pool, remove surface dirt and attachments with high-pressure water flow, and then use the spray anti-corrosion module to spray the inner and outer walls with anti-corrosion paint. The storage module is used to place the water tank 102, the material storage box 105, the hot air blower 301, and the information recording module. The obstacle detection module is used to detect whether there are obstacles or walls during the movement of the equipment. If no obstacles are detected, the equipment moves normally. If detected, the device is raised by the mobile module, and the free space below is used to directly cross over the obstacle.

[0063] Complete the work: The information recording module records the machine's operating trajectory, the parameters used by the cleaning module and the spray anti-corrosion module during operation, which are used to optimize the parameters used in subsequent work. When there are places on the inner and outer walls that are not completely cleaned or the anti-corrosion paint is sprayed unevenly, it is easy to find the cause.

[0064] The obstacle detection module includes a pressure sensor 2104, which is activated by the pressure generated when the device moves and hits an object. The obstacle detection module is installed in the front of the device and contacts the obstacle or wall before other parts of the device.

[0065] The mobile module includes a second electric stretching rod 2101, which is used to support the storage module, cleaning module and spray anti-corrosion module above. When the obstacle detection module detects an obstacle or a wall, the second electric stretching rod 2101 is raised so that the device can pass over the obstacle. When the second electric stretching rod 2101 is raised to the highest point and the pressure sensor 2104 is still activated for one minute, it is determined that a wall is encountered or the obstacle cannot be crossed, and the direction of the mobile module is changed to bypass the wall or obstacle.

[0066] The cleaning module also includes a drying module, which includes a hot air blower 301. While cleaning and spraying anti-corrosion, the drying module is used to dry the inner and outer walls where there is residual moisture, and heat the anti-corrosion paint that has been sprayed on the inner and outer walls to accelerate the curing of the paint.

[0067] Place the equipment in a suitable swimming pool to be treated. If the depth of the swimming pool is greater than the height of the entire equipment, the equipment cannot clean the outer wall. Check whether the water tank 102 and the material storage box 105 in the equipment are full. Start the equipment and move the equipment in the swimming pool through the moving module. Rinse and clean it through the cleaning module. Spray the anti-corrosion coating on the inner and outer walls with the spray anti-corrosion module. Finally, use the drying module to dry the inner and outer walls. On the one hand, it is used to dry the moisture on the inner and outer walls that have not been sprayed with the coating, and on the other hand, it is used to speed up the curing speed of the inner and outer walls of the sprayed coating. The obstacle detection module is used to detect moving obstacles, such as the water outlet pipe. When the obstacle detection module detects an obstacle through the pressure sensor 2104, An attempt is made to lift the device by moving the modules, use the extra space between the modules to cross the obstacle, and use the pressure sensor 2104 to continuously confirm whether the obstacle has been crossed. If the second electric stretching rod 2101 has reached its end or the pressure sensor 2104 is activated for a long time, it is determined that the obstacle has not been crossed or the wall of the swimming pool has been hit. The device is then rotated by the mobile module to turn and clean the inner and outer walls on the other side. The high-pressure water flow of the cleaning module is used to rinse and clean the dead corners in the swimming pool, and the angle and spraying speed of the spray anti-corrosion module are adjusted to perform targeted spraying on dead corners that are not easy to be evenly sprayed with paint. All information transmission and line connections within the modules are existing technologies.

Block 114 drives the first connecting plate 115 to move together, and the inner and outer walls are cleaned with high-pressure water through multiple high-pressure nozzles 117 on the water outlet plate 116. Water is transmitted by the first water pipe 124, and the second motor 121 is used to rotate the second rotating shaft 122 in the bearing 119 at the bottom of the second connecting plate 118. The movement of the second rotating shaft 122 is limited by the second limiting plate 120. The output angle of the bottom spray plate 123 is adjusted by the rotation of the second rotating shaft 122, so that the wall corners that the machine cannot move to can be sprayed, and the anti-corrosion paint in the storage box 105 is input into the spray plate 123 through the material pipe 125. The device is moved by the electric wheel 2102 at the bottom of the second electric stretching rod 2101. When encountering an obstacle, the push plate 2106 is squeezed backward, and the spring 2105 applies force to the pressure sensor 2104, so that the pressure sensor 2104 is activated, and the second electric stretching rod 2101 is controlled to extend, so that the base 101 moves upward, thereby freeing up space so that the device can pass over the obstacle. At the same time, the first electric stretching rod 103 is controlled to contract so that the top plate 104 moves downward, driving the multiple structures connected to the top plate 104 to move downward together, so that the working coverage area of ​​the high-pressure nozzle 117 and the spray plate 123 remains unchanged, and the device can pass over the obstacle. When the obstacle is crossed, the spring 2105 supports the push plate 2106 to return to its original position, and the pressure sensor 2104 loses pressure and automatically closes, then stops the extension of the second electric stretching rod 2101 and the contraction of the first electric stretching rod 103, and automatically resets to the original startup state after one minute. If the obstacle encountered is too high to be crossed or hits the wall, the pressure sensor 2104 will be activated for a long time. When the activation time of the pressure sensor 2104 reaches one minute, it is determined that it cannot be crossed and encounters a wall, and the electric wheel 2102 is automatically controlled to steer the device to avoid it, so as to prevent the device from being stuck in a fixed position and not moving.When the pressure sensor 2104 goes out within one minute after being activated, it is determined that an obstacle is being crossed, and the third electric stretching rod 2201 is started to extend, causing the bottom plate 2202 to move downward, and the third motor 2203 and the electric water gate 2209 are started. The obstacles at the bottom are cleaned by rotating the brush 2206 with the third rotating shaft 2204, and the water from the water tank 102 is sprayed onto the brush 2206 through the second water pipe 2208 through the water spray ring 2207 under the third connecting plate 2205. On the one hand, it can wet the brush 2206, and on the other hand, it can wash away some dirt and dust adhering to the brush 2206 through the water flow, thereby facilitating the cleaning of the brush 2206. Start the hot air blower 301, and transmit the hot air into the blowing plate 303 through the air duct 302, and blow the hot air onto the inner and outer walls through the enlarged opening. On the one hand, it can speed up the evaporation of residual moisture on the inner and outer walls, which is convenient for the adhesion of the sprayed paint to the inner and outer walls. On the other hand, it can heat the anti-corrosion paint sprayed on the inner and outer walls to speed up the curing of the paint. The screen 305 in the screen frame 304 at the output port of the blowing plate 303 can prevent small-volume debris from being stirred into the blowing plate 303 during high-pressure water flushing or hot air blowing. The fixation of the first connecting plate 115 and the fixation of the limiter 306 can prevent the air duct 302 from shaking during the hot air transmission, which makes its connection with the blowing plate 303 unstable.
