Description

Technical Field

[0001] This invention relates to the field of coal conveying system technology, specifically to a safety inspection device for cable trays in coal conveying corridors. Background Technology

[0002] A coal conveying system refers to the equipment and control equipment used to transport coal from the unloading point to the coal yard and from the coal yard to the boiler coal bunker. In a coal conveying system, coal conveying corridors are usually used to transport coal seams. Coal conveying corridors are similar to trenches and are generally underground or semi-underground concrete structures. Conveyors are installed in the corridors, and coal is transported through the corridors by conveyors. A large number of cable trays are installed in the coal conveying corridors. Due to the large amount of coal dust, ash is prone to accumulate inside the cable trays. If the internal cables are too hot or damaged, the accumulated coal ash can easily spontaneously combust. Therefore, regular inspections are required.

[0003] For example, the patent with application number CN201910353012.5 includes a cable tray mechanism, an opening mechanism disposed on the cable tray mechanism, a track mechanism disposed within the cable tray mechanism, an inspection mechanism disposed on the track mechanism, and a cable release and retraction mechanism for releasing cables to the inspection mechanism; the inspection mechanism includes a movable base disposed on the track mechanism, and a control mechanism, a power supply mechanism, and a monitoring mechanism are disposed on the movable base, and the control mechanism is communicatively connected to a monitoring center.

[0004] While the aforementioned patent can inspect cables inside cable trays, monitor temperature, humidity, and smoke, and provide feedback of internal images for staff to view and for locating fault points when malfunctions occur, making it easy to conduct inspections within cable tray mechanisms, it is not suitable for use in cable trays in coal conveying corridors because it cannot clean the coal ash accumulated inside.

[0008] As a preferred embodiment of the present invention, a dust collection chamber is provided on one side of the interior of the box, and a sealing door is installed on the outer wall of the box at the dust collection chamber. The dust collection assembly includes an air pump installed in the dust collection chamber. The air pump's suction port is sealed and connected to a dust collection main pipe. The end of the dust collection main pipe away from the air pump passes through the dust collection chamber and the connecting plate and extends into the U-shaped block. An air guide pipe is provided in the U-shaped block. The dust collection main pipe is connected to the air guide pipe. Several dust collection ports are evenly provided on the outer walls of the two side plates of the U-shaped block, and the several dust collection ports are connected to the air guide pipe.

[0009] As a preferred embodiment of the present invention, L-shaped cleaning brushes are fixedly installed on the outer walls of the two side plates of the U-shaped block on both sides of the dust suction port. The brush surface of each cleaning brush is in contact with the inner wall of the U-shaped groove plate, and the end face of each cleaning brush is flush with the end face of the U-shaped block.

[0010] As a preferred embodiment of the present invention, each drive assembly includes drive slots formed on both sides of the bottom of the housing. Each drive slot contains a gear, and one end of each gear extends out of the drive slot and meshes with an inner gear. A take-up slot is formed between the drive slots at the bottom of the housing. A rotating roller is formed in the take-up slot. A shielding film is wound around the outer wall of the rotating roller. A rotating shaft is fixedly connected to both ends of the rotating roller. The two rotating shafts extend through the side wall of the take-up slot into the drive slot, and the two gears are fixedly sleeved on the rotating shafts. A drive motor is installed at the bottom of the outer wall of the housing, and the output end of the drive motor is fixedly connected to one of the rotating shafts.

[0011] As a preferred embodiment of the present invention, the upper surface of the cover plate is respectively welded with fixing blocks at both ends, and the ends of the two shielding films away from the box body are fixedly connected to the side walls of the fixing blocks, and the width of the two shielding films is greater than the width of the moving groove.

[0012] As a preferred embodiment of the present invention, the detection mechanism includes a positioning sensor installed on one side inside the housing, a communicator on one side of the positioning sensor, the communicator being connected to a host computer in an external control room, a smoke sensor symmetrically installed on one end face of the U-shaped block, a monitoring camera between the two smoke sensors, the monitoring camera being installed inside the U-shaped block, and the lens of the monitoring camera being flush with the end face of the U-shaped block, and a wiping assembly on the outer wall of the U-shaped block on one side of the monitoring camera for cleaning dust adhering to the lens surface.

[0013] As a preferred embodiment of the present invention, the wiping assembly includes a housing fixedly installed on the outer wall of the U-shaped block, an electric telescopic rod installed inside the housing, the telescopic end of the electric telescopic rod extending through the housing to the outside and connected to a cleaning rod, and a brush attached to the side of the cleaning rod near the U-shaped block, at the point where the brush contacts the outer wall of the U-shaped block.

[0014] As a preferred embodiment of the present invention, the length of the cleaning rod is greater than the diameter of the monitoring camera lens.

[0015] As a preferred embodiment of the present invention, a slider is welded to the center of the lower surface of the U-shaped block. The slider is located in the groove and slidably connected thereto. Infrared thermal imagers are symmetrically arranged on both sides of the slider, and both infrared thermal imagers are mounted on the lower surface of the U-shaped block.

[0016] As a preferred embodiment of the present invention, a storage battery is located inside the housing, below the positioning sensor and the communicator installed in the detection mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Addressing the problems raised in the background art, the present invention uses a storage battery to power the inspection device, enabling the various electrical components in the detection mechanism to perform safety inspections inside the U-shaped channel plate. This allows personnel to monitor the situation from the control room. The drive motor in the drive assembly rotates the shaft, which in turn drives the gears and rotating rollers. The rotating gears, through meshing with the inner teeth, move the housing. Simultaneously, the shielding film in the forward direction tightens under the action of the rotating rollers, while the shielding film on the other side unfolds under the action of another rotating roller. This design ensures that the moving trough is always blocked when the box moves, reducing the possibility of coal ash entering through the trough. The moving box moves the U-shaped block via a connecting plate. The moving U-shaped block uses a cleaning brush to sweep off the coal ash adhering to the inner wall of the U-shaped trough plate. At this time, the air pump in the dust collection component works to generate suction at the dust collection port through the dust collection main pipe and air guide pipe, absorbing most of the swept-off coal ash and the coal ash that has accumulated inside and sending it into the ash collection chamber for collection. This allows the coal ash accumulated inside the cable tray to be cleaned when the inspection device inspects the inside of the cable tray, reducing the possibility of a large amount of coal ash spontaneously combusting.

[0029] The storage battery 206 in this application can power all electrical components in the inspection device 2, and it is detachable in the prior art, making it easy to replace.

[0030] Please see Figure 1-6 The present invention provides a technical solution:

[0031] A safety inspection device for cable trays in a coal conveying corridor includes a cable tray body 1 and an inspection device 2 installed inside it. The cable tray body 1 consists of a U-shaped channel plate 101 and a cover plate 102. A support block 1011 is integrally connected to the center of the U-shaped channel plate 101. A sliding groove 1012 is formed on the upper surface of the support block 1011. A moving groove 1021 is formed on the cover plate 102. The inspection device 2 includes a box body 201 set on the upper surface of the cover plate 102. A connecting plate 202 passing through the moving groove 1021 is welded to the lower surface of the box body 201. The connecting plate 202 extends to the inner wall of the U-shaped channel plate 101 and is welded with an inverted U-shaped block. 203. The U-shaped block 203 is equipped with a dust-collecting component 6 to absorb the coal ash accumulated in the cable tray body 1. The lower surface of the box 201 is equipped with drive components 3 on both sides of the long side. The upper surface of the cover plate 102 is equipped with inner teeth 1022 on both sides of the moving groove 1021. The actuating end of the drive component 3 is engaged with the inner teeth 1022 for the inspection device 2 to move along the moving groove 1021. The moving groove 1021 is covered with shielding films 7 on both sides of the box 201. One end of each shielding film 7 is connected to the drive component 3. The box 201 and the U-shaped block 203 are equipped with detection mechanisms 4 to ensure the safety of the inside of the cable tray body 1.

[0032] During safety inspections of cable trays in the coal conveying corridor, staff send signals to the inspection device 2 via the main unit in the control room. This activates various detection elements in the detection mechanism 4 within the inspection device 2 to perform safety checks on the interior of the cable tray body 1, allowing staff to understand the situation. Simultaneously, the drive assembly 3 and the dust extraction assembly 6 are activated. Drive assembly 3 causes the housing 201 to move the connecting plate 202 along the moving groove 1021 on the cover plate 102. The moving connecting plate 202 then moves the U-shaped block 203 within the U-shaped groove plate 101, coordinating with the detection machine. The structure 4 inspects the cables. At the same time, when the box 201 moves, the drive component 3 can unfold and rewind the shielding films 7 on both sides respectively, so that they can always shield the moving trough 1021, reducing the possibility of coal ash entering through the moving trough 1021. When the U-shaped block 203 moves, the dust collection component 6 works to clean and collect the coal ash attached to the inner wall of the U-shaped trough plate 101 and the coal ash accumulated thereon. Thus, when the inspection device 2 inspects the inside of the cable tray body 1, it can clean the coal ash inside, reducing the possibility of a large amount of coal ash spontaneously combusting.

[0033] For examples, please refer to Figure 2 , Figure 3 and Figure 6 The housing 201 has a dust collection chamber 2011 on one side of its interior. A sealing door 2012 is installed on the outer wall of the housing 201 at the dust collection chamber 2011. The dust collection assembly 6 includes an air pump 601 installed in the dust collection chamber 2011. The air pump 601's suction port is sealed and connected to a dust collection main pipe 602. The end of the dust collection main pipe 602 away from the air pump 601 extends through the dust collection chamber 2011 and the connecting plate 202 into a U-shaped block 203. An air guide pipe 60 is provided in the U-shaped block 203. 3. The main suction pipe 602 is connected to the air duct 603. Several suction ports 604 are evenly provided on the outer walls of the two side plates of the U-shaped block 203. The suction ports 604 are connected to the air duct 603. L-shaped cleaning brushes 605 are fixedly installed on both sides of the outer walls of the two side plates of the U-shaped block 203 at the suction ports 604. The brush surface of each cleaning brush 605 is in contact with the inner wall of the U-shaped groove plate 101, and the end face of each cleaning brush 605 is flush with the end face of the U-shaped block 203.

[0034] As the U-shaped block 203 moves, the moving U-shaped block 203 drives the cleaning brush 605 to sweep off the coal ash adhering to the inner wall of the U-shaped trough plate 101. At this time, the air pump 601 in the dust collection assembly 6 works, and through the dust collection main pipe 602 and the air guide pipe 603, several dust collection ports 604 generate suction, sucking up most of the swept-off coal ash and the coal ash accumulated inside the U-shaped trough plate 101 itself. The sucked-up coal ash is sent from the output port of the air pump 601 through the air guide pipe 603 and the dust collection main pipe 602 into the ash collection chamber 2011 for collection. The staff can periodically open the sealing door 2012 to clean the coal ash collected inside the ash collection chamber 2011.

[0035] For examples, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6Each drive assembly 3 includes drive grooves 301 on both sides of the bottom of the housing 201. Gears 304 are provided in each drive groove 301, with one end of each gear 304 extending out of the drive groove 301 and meshing with the inner gear 1022. A winding groove 306 is provided at the bottom of the housing 201 between the drive grooves 301. A rotating roller 305 is provided in the winding groove 306. A shielding film 7 is wound around the outer wall of the rotating roller 305. Rotating shafts 303 are fixedly connected to both ends of the rotating roller 305. The gears 304 extend through the side wall of the take-up groove 306 into the drive groove 301, and both gears 304 are fixedly sleeved on the rotating shaft 303. The bottom of the outer wall of the housing 201 is equipped with a drive motor 302. The output end of the drive motor 302 is fixedly connected to a rotating shaft 303. Fixing blocks 205 are welded to both ends of the upper surface of the cover plate 102. The ends of the two shielding films 7 away from the housing 201 are fixedly connected to the side wall of the fixing block 205, and the width of the two shielding films 7 is greater than the width of the moving groove 1021.

[0036] When the drive assembly 3 is working, the two drive motors 302 start synchronously, both driving the rotating shaft 303 to rotate. The rotating shaft 303 drives the installed gear 304 and rotating roller 305 to rotate. The rotating gear 304 drives the housing 201 to move under the meshing action of the inner tooth 1022. While the housing 201 moves, the shielding film 7 in the forward direction is tightened under the rotation of the rotating roller 305, and the shielding film 7 on the other side is unfolded under the rotation of another rotating roller 305. The fixing block 205 can restrict the shielding film 7 to prevent it from moving, so that the two shielding films 7 can always shield the moving groove 1021 when the housing 201 moves, reducing the possibility of coal ash entering the cable tray body 1 through the moving groove 1021. A protective box can be set on the outside of the drive motor 302 for its protection.

[0037] For examples, please refer to Figure 2 , Figure 3 and Figure 4The detection mechanism 4 includes a positioning sensor 401 installed inside one side of the housing 201. A communicator 402 is located on one side of the positioning sensor 401, and the communicator 402 is connected to the host computer in the external control room. Smoke sensors 404 are symmetrically installed on one end face of the U-shaped block 203. A monitoring camera 405 is located between the two smoke sensors 404. The monitoring camera 405 is installed inside the U-shaped block 203, and its lens is flush with the end face of the U-shaped block 203. The outer wall of the U-shaped block 203 is located within the monitoring camera's field of view. A wiping assembly 5 is provided on one side of the device 405 for cleaning dust adhering to the lens surface. The wiping assembly 5 includes a housing 501 fixedly installed on the outer wall of the U-shaped block 203. An electric telescopic rod 503 is installed inside the housing 501. The telescopic end of the electric telescopic rod 503 extends through the housing 501 to the outside and is connected to a cleaning rod 502. A brush 5021 is adhered to the side of the cleaning rod 502 near the U-shaped block 203. The length of the cleaning rod 502 is greater than the diameter of the lens of the monitoring camera 405. A slider 204 is welded to the center of the lower surface of the U-shaped block 203. The slider 204 is located in and slidably connected to the slide groove 1012. Infrared thermal imagers 403 are symmetrically arranged on both sides of the slider 204. Both infrared thermal imagers 403 are installed on the lower surface of the U-shaped block 203. Inside the housing 201, below the positioning sensor 401 and the communicator 402 installed in the detection mechanism 4, there is a storage battery 206.

[0038] The positioning sensor 401 in the detection mechanism 4 allows staff to know the location of the inspection device 2. The infrared thermal imager 403 can detect the heat of the cables passing by when the inspection device 2 moves. The smoke sensor 404 can monitor the dispersion of coal ash in the air inside the cable tray body 1. The monitoring camera 405 can record the interior of the cable tray body 1 during the inspection. All of the above information is transmitted to the host in the control room through the communicator 402, so that staff can understand the situation. When the monitoring camera 405 is working, the electric telescopic rod 503 in the wiping assembly 5 can be activated. The electric telescopic rod 503 pushes the cleaning rod 502 to move laterally. The moving cleaning rod 502 drives the brush 5021 to move past the lens of the monitoring camera 405 and wipe away the attached coal ash, which can ensure the clarity of the image. The power of the battery 206 is displayed on the host in the control room, so that staff can replace it in time.

[0039] The workflow of this invention is as follows: During safety inspections of cable trays in coal conveying corridors, the various detection elements in the detection mechanism 4 within the inspection device 2 can perform safety inspections on the interior of the cable tray body 1 and display the inspection information on the main unit in the control room, facilitating staff understanding of the situation. When the inspection device 2 needs to perform a safety inspection, the staff sends a signal to the inspection device 2 through the main unit in the control room, activating the drive assembly 3 and the dust extraction assembly 6. When the drive assembly 3 is working, the two drive motors 302 start synchronously, both driving the rotating shaft 303 to rotate. The rotating shaft 303 drives the installed gear 304 and rotating roller 305 to rotate. The rotating gear 304, under the meshing action of the inner tooth 1022, drives the housing 201 to move. While the housing 201 moves, the shielding film 7 in the forward direction is tightened by the rotation of the rotating roller 305, and the shielding film 7 on the other side is tightened by another rotating roller 305. The 05 rotates and unfolds. The moving box 201 drives the connecting plate 202 to move along the moving groove 1021 on the cover plate 102. The moving connecting plate 202 drives the U-shaped block 203 to move inside the U-shaped groove plate 101. It works with the detection mechanism 4 to inspect the cable. When the U-shaped block 203 moves, it drives the cleaning brush 605 to sweep off the coal ash attached to the inner wall of the U-shaped groove plate 101. At this time, the air pump 601 in the dust collection component 6 works. Through the dust collection main pipe 602 and the air guide pipe 603, several dust collection ports 604 generate suction to suck up most of the swept coal ash and the coal ash accumulated inside the U-shaped groove plate 101. The sucked coal ash is sent from the output port of the air pump 601 to the ash collection chamber 2011 for collection through the air guide pipe 603 and the dust collection main pipe 602. The staff can periodically open the sealing door 2012 to clean the coal ash collected inside the ash collection chamber 2011.

[0040] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
