Description

Technical Field

[0001] This invention relates to the field of tank surface anti-corrosion technology, and in particular to an automatic light curing device for the surface of soil-covered tanks based on drones. Background Technology

[0002] Conventional tank surfaces typically require rust removal and corrosion protection. Since soil-covered tanks are covered with soil, they require even more corrosion protection, and the requirements for corrosion protection are higher. They must not only resist air corrosion but also prevent soil corrosion. Therefore, it was decided to use a method of spraying epoxy zinc-rich primer on the outer surface of the tank and attaching light-cured material to the outside for corrosion protection. At the same time, the nominal thickness of the soil-covered tank cylinder is maintained, thereby reducing the thickness of the steel used in the tank, reducing the weight of the tank and manufacturing costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic photocuring device for the surface of a soil-covering tank based on a drone. The device includes a soil-covering tank, a photocuring unit, and a drone. The drone is used for panoramic scanning of the soil-covering tank and specifically includes a drone body, propellers, and a detection device. The photocuring unit includes a feeding area, a cutting area, a material transport trolley, a tilting area, a spraying area, a detection and repair area, and a tilting device.

The feeding area is seamlessly connected to the cutting area, ensuring the material transport trolley can travel in a straight line to the cutting area. The material transport trolley is used to transport the photocurable material to each area. The tilting area is seamlessly connected to the cutting area; after cutting, the material transport trolley transports the photocurable material to the tilting area. The spraying area is located on both sides of the tilting area, and the detection and repair area is located on the back of the tilting area. The tilting device is located at the end of the photocuring unit and can tilt the material transport trolley 180° to adhere the photocurable material to the soil-covering tank.

When the flipping device motor rotates in the opposite direction, the flipping device rotation auxiliary spring exerts force to pull the flipping device base plate back to the initial state.

[0008] Preferably, the spraying area includes an epoxy zinc-rich paint can, a spray pipe, and a spray nozzle. The vertical part of the spray pipe can swing left and right within a range of 0-45°.

[0043] All movements and operations of the feeding area 220, cutting area 206, material transport trolley 210, tilting area 221, spraying area 231 and inspection and repair area 232 are controlled by the central control device 230.

[0044] Both the inlet door 201 and the delivery door 203 are sliding doors. When feeding material, the inlet door 201 is opened and the delivery door 203 is closed. After the secondary storage silo for UV-curable materials 202 is full, the inlet door 201 is closed. When delivering material, the delivery door 203 is opened, and the material transport trolley 210 waits to receive the material at the bottom of the loading area 204. Each time the delivery door 203 is opened, only one piece of material is allowed to fall into the material transport trolley 210.

[0045] The loading area 220 is seamlessly connected to the cutting area 206, ensuring that the material transport trolley 210 travels in a straight line from the loading area 204 to the cutting area 206.

[0046] The cutting blade 207 is suspended under the top plate 233 of the cutting area. The cutting blade 207 can adjust the cutting position, cutting angle and cutting depth according to the cutting requirements.

[0047] The flipping area 221 is seamlessly connected to the cutting area 206. After cutting, the material transport trolley 210 immediately transports the photocurable material to the flipping area 221.

[0048] The flipping device 234 is located at the end of the photocuring device 200, which can flip the material transport trolley 210 180° to attach the photocuring material to the can 100 for bonding.

[0049] The spraying area 231 is located on both sides of the flipping area 221, and the vertical part of the spraying pipe 223 can swing left and right within a range of 0-45° to expand the spraying range; the spraying nozzle 224 can adjust the diameter of the spraying nozzle as needed.

[0050] The inspection and repair area 232 is located on the back of the flipping area 221. The paint film inspection device 225 and the film cutting knife 226 are close to the end of the light curing device 200. The ultraviolet lamp 227 is located behind the paint film inspection device 225.

[0051] The motion device 205 of the light curing device is located at the end of the light curing device 200 and behind the ultraviolet lamp 227, respectively.

[0052] The motion device 205 of the photocuring unit can turn around the center point;

[0053] The material handling trolley motion device 211 can rotate 90°.

[0054] The tire 2114 of the material transport trolley motion device is a petal-shaped tire made of rubber, with gaps between the petals, the gaps being the thickness of the bottom plate 208 of the tilting device;

[0055] When the device is tilted, the tires 2114 of the material handling trolley are fixedly connected to the bottom plate 208 of the tilting device.

[0056] The rolling track 2052 of the photocuring device is a magnetic adsorption track. It is not magnetic when moving, but becomes magnetic when stopped, ensuring that the photocuring device 200 does not slip when it stops moving.

[0057] The main power unit 229 of the photocuring device is located directly below the cutting area 206;

[0058] The central control device 230 is located on the back of the feeding area 220;

[0059] The above-mentioned method for automatic photocuring of soil covering tank surfaces based on drones includes the following stages:

[0060] (1) The UAV device 300 performs a panoramic scan of the soil covering tank 100, measures the specific dimensions of the soil covering tank 100, and plans the pasting according to the conventional dimensions of the light-curing material;

[0061] (2) During the pasting planning process, the pasting position, shape, size and sequence of each piece of UV-curable material are recorded and numbered; for UV-curable material of special size, a trimming plan is proposed and marked according to the number; all the above information is sent to the central control device 230 of the UV-curing device 200;

[0062] (3) When the UAV device 300 is scanning, the photocuring device 200 sprays epoxy zinc-rich paint on the surface of the soil covering tank 100.

[0063] (4) The light curing device 200 first performs a test spray on the surface of the soil covering tank 100. Under the condition of fixed spraying angle and spray nozzle 224 diameter, the thickness of one spray is measured by the paint film detection device 225, and the number of repeated spraying is determined according to the thickness.

[0064] (5) Because the light curing device 200 is heavy and the magnetic adsorption force of the rolling track 2052 of the light curing device is limited, the light curing device 200 only sprays and pastes the light curing material within the range of "11 points to 1 point" of the cross section of the soil covering tank 100.

[0065] (6) Within the range of “11 o’clock to 1 o’clock” of the cross section of the soil covering tank 100, the light curing device 200 moves in a backward “z” shape to ensure that the travel path does not cause pollution or damage to the spraying area;

[0066] (7) After the coating of the 100 section of the soil-covered tank is completed along the axis of the tank, the paint film detection device 225 measures the thickness of the coated area and re-sprays the areas that do not meet the thickness requirements.

[0067] (8) After the touch-up spraying is completed, the roller frame 102 drives the soil covering tank 100 to rotate 60°, and the light curing device 200 continues to spray in the new position;

[0068] (9) After the initial spraying time exceeds 60 minutes, the photocuring device 200 opens the feed door 201 to start feeding;

[0069] (10) When the secondary storage 202 of the photocurable material is full, the feeding door 203 is opened and the photocurable material falls into the material transport trolley 210 in the loading area 204 to complete the loading.

[0070] (11) The drone device 300 sends the planned starting position for pasting to the photocuring device 200, and the photocuring device 200 moves to the starting position;

[0071] (12) The material transport trolley 210 transports the photocurable material to the cutting area 206;

[0072] (13) The central control device 230 controls the cutting blade 207 to cut according to the shape and size requirements of the photocurable material planned by the UAV device 300; at the same time, the UAV device 300 sets the status of the photocurable material at that position in the planning diagram to "cutting".

[0073] (14) After cutting, the material transport trolley 210 transports the photocurable material to the flipping area 221;

[0074] (15) The UAV device 300 scans and measures the shape and size of the photocurable material in the material transport trolley 210, and compares it with the shape and size of the photocurable material in the "cutting" state shown in the planning diagram. If the comparison meets the requirements, it is flipped over; if it does not meet the requirements, the photocurable material is dropped from the end of the soil covering tank 100 and the manual decision is made on whether it is usable.

[0075] (16) After the photocurable material in the material transport trolley 210 meets the requirements, the rotating connecting shaft 2112 of the material transport trolley motion device rotates 90°, so that the tire 2114 of the material transport trolley motion device is just stuck on the bottom plate 208 of the tilting device, thus realizing the fixed connection between the material transport trolley 210 and the tilting device 234.

[0076] (17) The motor 216 of the flipping device starts to start, driving the bottom plate 208 of the flipping device to rotate upward; at the same time, the lifting device 217 starts to lift the bottom plate 208 of the flipping device away from the horizontal state, thereby assisting the motor 216 of the flipping device to drive the bottom plate 208 of the flipping device to flip.

[0077] (18) When the bottom plate 208 of the flipping device flips to a vertical state, the motor 216 of the flipping device accelerates the rotation speed, so that the bottom plate 208 of the flipping device drives the material transport trolley 210 to quickly press the light-curing material onto the surface of the soil covering tank, so as to prevent the light-curing material from sliding out of the material transport trolley 210.

[0078] (19) After the material transport trolley 210 unloads the light-curing material, the motor 216 of the flipping device starts to rotate in the opposite direction, and at the same time the auxiliary spring 218 of the flipping device starts to exert force, together pulling the bottom plate 208 of the flipping device back to the initial state.

[0079] (20) The rotating connecting shaft 2112 of the material transport trolley motion device rotates 90° again, disengages from the bottom plate 208 of the tilting device, and begins to move towards the loading area 204 to start the next round of material transport;

[0080] (21) The UAV device 300 begins to scan the surface of the newly applied photocurable material. After discovering quality phenomena such as hollowness, it marks the photocurable material with the corresponding number on the planning map.

[0081] (22) When the photocuring device 200 has finished applying the photocurable material within the range of "11 o'clock - 1 o'clock" on the cross section of the tank 100, the photocuring device 200 moves to the location where the UAV device 300 scans and finds a quality problem. The cutting blade 226 cuts the location, releases the gas, and uses the ultraviolet lamp 227 to accelerate the curing process, ensuring that the photocuring device 200 can bear the load. At the same time, the UAV device 300 marks the status of the photocurable material at that location in the planning diagram as "completed".

[0082] (23) Subsequently, the photocuring device 200 also applies the photocuring material to the second area in a reverse manner; until all photocuring materials are applied.

[0083] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
