Description

Technical Field

[0001] This invention relates to the field of inspection equipment technology, specifically to an explosion-proof intelligent inspection device. Background Technology

[0002] Explosion-proof inspection equipment has applications in many fields. Due to special needs, it is used in special scenarios, such as hazardous and explosive environments like coal mines and petrochemical plants. This significantly reduces the workload and intensity of maintenance personnel and effectively improves safety protection levels. However, in the event of an explosion, the transparent panel in front of the camera can be damaged by flying debris, causing the camera to become blurry or unable to see clearly when monitoring the situation through the panel. This makes it difficult to effectively understand the surrounding conditions during or after an explosion, rendering the camera unsuitable for use during or after an explosion. Summary of the Invention

[0003] In view of the shortcomings of the existing technology and to overcome its defects, the present invention aims to provide an explosion-proof intelligent inspection device to solve the problem that cameras are not convenient to use during or after an explosion.

[0004] The technical solution is an explosion-proof intelligent inspection device, including a mobile frame mounted on a track, a protective box rotatably connected to the mobile frame, a first through hole and a second through hole on the same side of the protective box, a reflective unit for reflecting light installed inside the protective box, a first motor installed inside the protective box, and a camera installed on the output shaft of the first motor, forming a structure in which the camera monitors the outside world through the first through hole or through the cooperation of the reflective unit and the second through hole. A protective plate made of transparent material is detachably and fixedly connected to the protective box at the first through hole, forming a structure in which the protective plate moves away from the first through hole when subjected to external force. A contact switch for controlling the operation of the first motor is installed between the protective plate and the protective box.

[0005] Preferably, the reflective unit includes a corner-shaped reflective tube, and a reflective surface is provided at the corner of each reflective tube.

[0006] Preferably, a fixing cover is provided on the outer side of the protective box at the first through hole, and an opening corresponding to the first through hole is provided on the fixing cover. The fixing cover is detachably and fixedly connected to the protective plate at the opening, and an outlet for the protective plate to pass through is provided below the fixing cover between the protective plate and the first through hole.

[0007] Preferably, a sealing block is installed at the camera, and the side of each sealing block away from the axis of the first motor output shaft is a cylindrical arc surface with the axis of the first motor output shaft as the central axis, forming a structure in which the sealing block seals the first through hole when the camera does not correspond to the first through hole.

[0008] Preferably, a first limiting block and a second limiting block are installed inside the protective box to restrict the rotational displacement of the camera, and the camera is located between the first limiting block and the second limiting block.

[0009] Preferably, the mobile frame includes mounting bases, each mounting base being rotatably connected to the housing, a third motor being mounted on the housing, a protective box being mounted on the output shaft of the third motor, a drive motor being fixedly connected to each mounting base, the track having a "T" shaped structure, a traveling wheel for cooperating with the upper surface on both sides of the track being mounted on the output shaft of the drive motor, and a limiting wheel for cooperating with the end faces on both sides of the track being rotatably connected to each mounting base.

[0010] Preferably, each of the reflector tubes is fixedly connected to the mounting block, and a second motor is installed inside the protective box. The mounting block is fixedly connected to the output shaft of the second motor, forming a structure in which one of the reflector tubes is aligned with the camera at one end and with the second through hole at the other end through the operation of the second motor.

[0011] Preferably, the mounting block is provided with a stop for closing the second through hole, and each of the reflective tubes is provided with a baffle made of transparent material at one end corresponding to the second through hole.

[0012] Preferably, the contact switch includes a first elastic sheet and a second elastic sheet that cooperate with each other and are made of elastic material. The first elastic sheet and the second elastic sheet have an arc-shaped structure. The first elastic sheet and the second elastic sheet are mounted on a fixed cover. A partition made of insulating material is installed on the protective plate to isolate the first elastic sheet and the second elastic sheet.

[0013] Preferably, the axes of all the traveling wheels and limiting wheels on the same mounting base are located on the same plane.

[0014] This invention provides an explosion-proof intelligent inspection device, which has the following advantages compared with the prior art:

[0015] 1. When an explosion occurs, if the protective plate is hit by the blast debris, the protective plate separates from the protective box and moves away from the first through hole. The contact switch closes, causing the first motor to rotate. The camera rotates to the reflector unit and monitors the outside world through the cooperation of the reflector unit and the second through hole, thereby preventing the camera from being damaged by the blast debris. In addition, after the explosion, the first motor can also be rotated so that the camera can monitor the outside world again through the first through hole, making it convenient for the camera to be used during or after the explosion.

[0016] 2. By using the second motor, when one reflector is affected by the debris from the explosion, the next reflector is aligned with the camera and the second through hole, thus facilitating monitoring of the outside world during an explosion. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0033] Please see Figure 1-12This invention provides a technical solution: an explosion-proof intelligent inspection device, including a movable frame 1 mounted on a track 14, a protective box 2 rotatably connected to the movable frame 1, a first through hole 3 and a second through hole 4 on the same side of the protective box 2, a reflective unit 5 for reflecting light installed inside the protective box 2, a first motor 6 bolted inside the protective box 2, a camera 7 mounted on the output shaft of the first motor 6, wherein a fixed support plate is keyed to the output shaft of the first motor 6, and the support plate is bolted to the camera 7, forming a structure in which the camera 7 monitors the outside world through the first through hole 3 or through the cooperation of the reflective unit 5 and the second through hole 4, the protective box 2 is detachably fixed to a protective plate 8 made of transparent material such as transparent plastic at the first through hole 3, forming a structure in which the protective plate 8 moves away from the first through hole 3 when subjected to external force, and a control device is installed between the protective plate 8 and the protective box 2. The contact switch 9 controls the operation of the first motor 6. The contact switch 9 is electrically connected to the first motor 6 via a wire. Under normal use, the camera 7 corresponds to the first through hole 3 and monitors the outside world through the first through hole 3. The protective box 2 protects the camera 7. At this time, the protective plate 8 protects the camera 7, and the contact switch 9 is open. When an explosion occurs, if the protective plate 8 is hit by the explosion debris, the protective plate 8 separates from the protective box 2 and moves away from the first through hole 3. The contact switch 9 closes, causing the first motor 6 to rotate. The camera 7 rotates to the reflector unit 5 and monitors the outside world through the cooperation of the reflector unit 5 and the second through hole 4, thereby preventing the camera 7 from being damaged by the explosion debris. In addition, after the explosion, the first motor 6 can also be rotated so that the camera 7 can monitor the outside world again through the first through hole 3, making it convenient for the camera 7 to be used during or after the explosion.

[0034] In one embodiment, the reflective unit 5 includes a corner-shaped reflective tube 5.1, and a reflective surface 5.2 is provided at the corner of each reflective tube 5.2. The reflective surface 5.2 can be a mirror or other suitable structure. The reflective tube 5.1 prevents the explosion debris that moves to the second through hole 4 from damaging the camera 7, and facilitates the camera 7 to detect the outside world during an explosion.

[0035] In one embodiment, each reflector 5.1 is fixedly connected to the mounting block 5.3, and the reflector 5.1 and the mounting block 5.3 are an integral structure. A second motor 5.4 is bolted inside the protective box 2, and the output shaft of the second motor 5.4 is keyed to the mounting block 5.3, forming a structure where, through the operation of the second motor 5.4, one end of each reflector 5.1 corresponds to the camera 7, and the other end corresponds to the second through hole 4. The number of reflectors 5.1 is a suitable number, such as eleven. When the camera 7 rotates to the reflector 5.1, one end of each reflector 5.1 corresponds to the camera 7, and the other end corresponds to the second through hole 4, thereby allowing the camera 7 to monitor the outside world through the cooperation of the reflective unit 5 and the second through hole 4. When this reflector 5.1 is exploded and fragmented... When affected by an object, the second motor 5.4 rotates, causing the next reflector 5.1 to align with the camera 7 and the second through hole 4. This forms a structure where, through the operation of the second motor 5.4, one end of each reflector 5.1 aligns with the camera 7, and the other end aligns with the second through hole 4. This facilitates monitoring of the outside world during an explosion. When the camera 7 aligns with the first through hole 3, it monitors the outside world through the first through hole 3. When the camera 7 rotates to the reflector 5.1, one end of each reflector 5.1 aligns with the camera 7, and the other end aligns with the second through hole 4. This allows the camera 7 to monitor the outside world through the cooperation of the reflector unit 5 and the second through hole 4. This forms a structure where the camera 7 monitors the outside world through the first through hole 3 or through the cooperation of the reflector unit 5 and the second through hole 4.

[0036] In one embodiment, a stop 5.5 for sealing the second through hole 4 is provided on the mounting block 5.3. The stop 5.5 and the mounting block 5.3 are an integral structure. The stop 5.5 is formed on the part of the mounting block 5.3 located between the two reflector tubes 5.1. When the camera 7 corresponds to the first through hole 3, the stop 5.5 seals the second through hole 4. A baffle 5.6 made of transparent material such as transparent plastic is snapped onto the end of each reflector tube 5.1 that corresponds to the second through hole 4. The baffle 5.6 prevents explosive debris from entering the reflector tube 5.1. When the baffle 5.6 is damaged, the second motor 5.4 rotates, so that the next reflector tube 5.1 corresponds to the camera 7 and the second through hole 4.

[0037] In one embodiment, the protective box 2 has a cylindrical blank area at the mounting block 5.3 that mates with the mounting block 5.3, so that the mounting block 5.3 can rotate inside the protective box 2.

[0038] In one embodiment, a fixing cover 2.1 is provided on the outer side of the protective box 2 at the first through hole 3. The fixing cover 2.1 is welded and fixed to the box body of the protective box 2, or it can be an integral structure. The fixing cover 2.1 has a through hole 2.2 corresponding to the first through hole 3. The fixing cover 2.1 is detachably and fixedly connected to the protective plate 8 at the through hole 2.2. The fixing cover 2.1 has an outlet 2.3 below the protective plate 8 between the protective plate 8 and the first through hole 3 for the protective plate 8 to pass through. When the protective plate 8 is impacted, the protective plate 8 separates from the fixing cover 2.1 and moves downward through the outlet 2.3, thereby moving away from the first through hole 3. The upper and lower sides of the protective plate 8 are inclined, and the left and right sides have slots 15. The fixing cover 2.1 is provided with a locking strip 16 that cooperates with the slots 15. The locking strip 16 and the slots 15 are connected by the locking strip 16. The cooperation of 5 allows the protective plate 8 to be snapped and fixed to the fixed cover 2.1. When the protective plate 8 is impacted, it is easy to separate from the fixed cover 2.1. This allows the protective plate 8 and the fixed cover 2.1 to be both fixed and detachable, making the protective plate 8 and the fixed cover 2.1 detachably fixed. This also allows the protective plate 8 to be detachably fixed to the protective box 2. At the same time, the protective plate 8 can be moved away from the first through hole 3 through the outlet 2.3, thus forming a structure in which the protective plate 8 moves away from the first through hole 3 after being subjected to external force. Alternatively, the protective plate 8 can have another structure, with all sides of the protective plate 8 being inclined, i.e., the protective plate 8 is a platform-shaped structure. The protective plate 8 is partially bonded and fixed to the fixed cover 2.1 on the side using adhesives such as 502 glue, so that the protective plate 8 can be separated from the fixed cover 2.1 when it is impacted.

[0039] In one embodiment, the contact switch 9 includes a first elastic sheet 9.1 and a second elastic sheet 9.2 that cooperate with each other and are made of an elastic material such as spring steel. The first elastic sheet 9.1 and the second elastic sheet 9.2 have an arc-shaped structure and are bonded and fixed to the fixing cover 2.1. A partition 9.3 made of insulating material is installed on the protective plate 8 to isolate the first elastic sheet 9.1 and the second elastic sheet 9.2. The partition 9.3 and the protective plate 8 are an integral structure. The partition 9.3 is made of transparent plastic. When the protective plate 8 is fixed to the fixing cover 2.1, the first elastic sheet 9.1 and the second elastic sheet 9.2 are separated through the partition 9.3, and the contact switch 9 is open. When the protective plate 8 is separated from the fixing cover 2.1, the first elastic sheet 9.1 and the second elastic sheet 9.2 are in contact, and the contact switch 9 is closed. The first elastic sheet 9.1 and the second elastic sheet 9.2 are electrically connected to the first motor 6 through wires.

[0040] In one embodiment, a sealing block 10 is installed at the camera 7. The sealing block 10 is bonded and fixed to the outer shell of the camera 7. There are two sealing blocks 10, located on both sides of the camera 7. The side of each sealing block 10 away from the axis of the output shaft of the first motor 6 is a cylindrical arc surface with the axis of the output shaft of the first motor 6 as the central axis. This forms a structure in which the sealing block 10 closes the first through hole 3 when the camera 7 is not aligned with the first through hole 3. When the camera 7 is aligned with the first through hole 3, each sealing block 10 is located on both sides of the first through hole 3. When the camera 7 rotates to other positions, the sealing block 10 closes the first through hole 3. This structure forms a structure in which the sealing block 10 closes the first through hole 3 when the camera 7 is not aligned with the first through hole 3, which facilitates the protection of the camera 7 and the components inside the protective box 2 at the first through hole 3 in the event of an explosion.

[0041] In one embodiment, a first limiting block 11 and a second limiting block 12, which restrict the rotational displacement of the camera 7, are bolted inside the protective box 2, and the camera 7 is located between the first limiting block 11 and the second limiting block 12.

[0042] In one embodiment, the movable frame 1 includes two mounting bases 1.1, each rotatably connected to a housing 1.2. A third motor 1.3 is bolted inside the housing 1.2, and a protective box 2 is mounted on the output shaft of the third motor 1.3. The portion of the output shaft of the third motor 1.3 extending outside the housing 1.2 is keyed to the protective box 2. A drive motor 1.4 is bolted to each mounting base 1.1. The track 14 has a "T"-shaped structure, and a key is keyed to the output shaft of the drive motor 1.4 for... The upper surfaces of the track 14 are fitted with the wheels 1.5. Each mounting base 1.1 is rotatably connected to a limiting wheel 1.6 for fitting with the end faces of the track 14. There are four drive motors 1.4, wheels 1.5, and limiting wheels 1.6. The drive motor 1.4 drives the wheels 1.5, causing the moving frame 1 to move. The limiting wheels 1.6 limit the left and right movement of the moving frame 1 on the track 14. The mounting base 1.1 has a protective cover 1.7 welded to the outside of the drive motor 1.4.

[0043] In one embodiment, the axes of each traveling wheel 1.5 and the limiting wheel 1.6 on the same mounting base 1.1 are located on the same plane. When the track 14 is bent, the moving frame 1 can also move on the track 14.

[0044] In one embodiment, the protective box 2 is bolted to the two sides of the first through hole 3 to fix the supplementary light 13. There are two supplementary lights 13 to provide supplementary lighting to the front of the camera 7.

[0045] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
