Description

Technical Field

[0001] This utility model relates to the field of shell processing technology, specifically to a surface anti-corrosion treatment device for explosion-proof shells used in mining. Background Technology

[0002] The explosion-proof enclosure has sufficient mechanical strength to withstand the high temperature and pressure generated by possible explosions of flammable gases or dust inside. It encloses electrical sparks, arcs, or high-temperature components generated by electrical equipment in a robust enclosure, preventing them from directly contacting the external explosive environment and fundamentally eliminating ignition sources.

[0003] Because the underground environment is extremely harsh and highly corrosive to metal materials, rust on the outer shell can lead to increased gaps, increased surface roughness, or pits, which can damage the original explosion-proof path. Therefore, anti-corrosion treatment can improve the reliability of the explosion-proof outer shell.

[0004] However, explosion-proof enclosures often suffer from blistering and peeling of the coating. This is because the enclosure blanks are sprayed without inspection after degreasing during the anti-corrosion process. After inspection, the enclosure blanks need to be dehumidified and dried as a whole, which makes the process more complicated. Therefore, this utility model proposes a surface anti-corrosion treatment device for explosion-proof enclosures used in mining that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a surface anti-corrosion treatment device for explosion-proof enclosures used in mining, so as to solve the problems mentioned in the background art.

[0009] The ring body has a rubber stop ring at the bottom. The ring body is connected to the horizontal plate through a lifting assembly. The ring body is equipped with two sets of detection assemblies. The detection assemblies include a straight pipe and a vision probe. The straight pipe has a nozzle and is connected to an external hose and is controlled by a control valve to supply water. The vision probe is used to capture the shape of the water sprayed from the nozzle on the surface of the outer shell.

[0010] A telescopic rod is located between the two sets of detection components. The telescopic rod is rotatably connected to the horizontal plate, and a liner is provided at the bottom end of the telescopic rod.

[0025] The following is a detailed description of a surface anti-corrosion treatment device for explosion-proof enclosures used in mining, according to embodiments of the present disclosure, with reference to the accompanying drawings. To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions in the embodiments of this disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0026] Therefore, the following detailed description of embodiments of the present disclosure provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely to illustrate selected embodiments of the disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without inventive effort are within the scope of protection of the present disclosure.

[0027] Example 1

[0028] Please see Figure 1 The base 10 is set on the anti-corrosion conveyor line, which is located close to the workshop. After the outer shell is degreased and dried, it is conveyed and moved on the anti-corrosion conveyor line.

[0029] The front end of the bracket 20 is connected to a horizontal plate 21. The bracket 20 and the base 10 are slidably fitted together in a T-shaped structure. The bracket 20 can slide and adjust the extension distance of the horizontal plate 21 on the base 10. Multiple sets of sleeves are arranged at intervals on the bracket 20. The base 10 has a frame, and a positioning rod through the frame can insert a set of sleeves. By controlling the insertion of different sleeves by the positioning rod, the bracket 20 is limited after adjustment.

[0030] Please see Figure 1 , Figure 2 The bottom of the ring body 30 is provided with a rubber abutment ring 31. The ring body 30 is connected to the horizontal plate 21 through the lifting assembly 60. The lifting assembly 60 is used to drive the ring body 30 to rise and fall vertically. The lifting assembly 60 includes a servo cylinder 61 and a guide rod 62. The movable rod of the servo cylinder is connected to the ring body 30. The guide rod 62 is movably inserted through the horizontal plate 21 and connected to the ring body 30.

[0031] When the housing moves to below the ring 30, the servo cylinder 61 drives the ring 30 to move downward, so that the rubber abutment 31 abuts against the plane of the housing to isolate the area surrounded by the ring 30, and the area surrounded by the ring 30 is the detection area.

[0032] Please see Figure 2 , Figure 3 Two sets of detection components 40 are provided on the ring body 30. The two sets of detection components 40 are distributed at intervals to form a control detection. The detection component 40 includes a light strip, a straight tube 41 and a vision probe 42. The straight tube 41 has a nozzle 411 and is connected to an external hose and is controlled by a control valve to supply water. The external hose and the control valve are not shown in the figure. The vision probe 42 is used to photograph the shape of the water sprayed from the nozzle 411 on the surface of the outer shell.

[0033] During the testing process, the control valves control pure water to spray from nozzles 411 at two sets of straight pipes 41. The water sprayed from the nozzles 411 sprays onto the surface of the housing within the testing area. Two sets of vision probes 42 take multiple photos within 10-30 seconds after the nozzles 411 spray water, with each photo taking more than 1 second. The photos taken by the two sets of vision probes 42 are uploaded to the processor via the network for processing and identification. The images are then detected by algorithms. If the sprayed water forms a uniform, continuous, and unbroken water film on the housing surface, it indicates that the oil removal is thorough. If isolated water droplets are formed, it indicates that the oil removal is incomplete. When incomplete oil removal is detected, the corresponding housing is marked by indicator lights or signal transmission.

[0034] Please see Figure 1 , Figure 3 The telescopic rod 50 is located between the two sets of detection components 40. The telescopic rod 50 is rotatably connected to the horizontal plate 21, and a liner 51 is provided at the bottom of the telescopic rod 50. The liner 51 is movably fitted with the ring body 30. A moisture-absorbing sponge 2 is provided on the underside of the liner 51. A motor body 53 is installed on the horizontal plate 21. The output end of the motor body 53 is connected to the telescopic rod 50 through a gear set 54.

[0035] The motor body 53 provides power to rotate the telescopic rod 50. The telescopic rod 50 can be assembled using a keyed connection, allowing it to rotate and extend. The telescopic rod 50 extends and retracts with the rise and fall of the ring body 30. During testing, the absorbent sponge 2 is positioned between the two sets of straight pipes 41 and contacts the shell surface. After the vision probe 42 completes its imaging, the telescopic rod 50 drives the liner 51 to rotate on the ring body 30, causing the absorbent sponge 2 to absorb the water sprayed onto the shell surface. The liner 51 completes at least one full rotation on the ring body 30, thereby covering and absorbing the water on the shell with the absorbent sponge 2. Finally, the servo cylinder 61 drives the ring body 30 to reset upwards, causing the rubber abutment 31 to detach from the shell, thus completing the test and achieving the detection of the shell's oil removal effect. This ensures the quality of the shell's anti-corrosion treatment. Furthermore, the tested area is dehumidified after testing, eliminating the need for overall drying and simplifying the anti-corrosion treatment process.

[0036] Example 2

[0037] Please see Figure 2 , Figure 3 The ring body 30 has an air guide cavity, and multiple sets of air holes 32 are connected to the inner side of the air guide cavity. The multiple sets of air holes 32 are symmetrically distributed and correspond to two sets of detection components 40 respectively. A suction fan 22 is installed on the upper end of the horizontal plate 21. Multiple sets of air supply hoses 23 are connected to the outlet end of the suction fan 22. The multiple sets of air supply hoses 23 extend and connect to the air guide cavity. Each set of air supply hoses 23 is wound around a set of guide rods 62.

[0038] After the water sprayed onto the surface of the housing is adsorbed in the above embodiment, the suction fan 22 works to discharge clean air through the air delivery hose 23 from multiple sets of air holes 32. The discharged clean air flows through the detection surface of the housing, thereby achieving a drying effect, effectively improving the dehumidification effect and avoiding moisture residue.

[0039] Please see Figure 4 A liquid collection tank 11 is installed on the base 10. Inside the liquid collection tank 11, there is a squeezing block 12 that can contact the moisture-absorbing sponge 2. By moving the bracket 20, the moisture-absorbing sponge 2 moves to the top of the squeezing block 12. Then, the ring body 30 is driven into the liquid collection tank 11 by the servo cylinder 61, so that the moisture-absorbing sponge 2 contacts the squeezing block 12, thereby squeezing out the water absorbed by the moisture-absorbing sponge 2 and ensuring the moisture absorption effect of the moisture-absorbing sponge 2.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
