Description

Technical Field

[0001] The utility model relates to the technical field of mining cameras, in particular to an intrinsically safe thermal imaging camera for mining. Background Art

[0002] In coal mines, the gas content is high and there is a lot of coal dust. The instruments and equipment in the mine are in an environment containing flammable and explosive gases. For safety reasons, thermal imaging cameras need to be installed inside the mine to better monitor the inside of the mine. The camera needs to monitor the mine tunnel for a long time, so the camera angle needs to be adjusted and fixed during installation.

[0003] An existing intrinsically safe thermal imaging camera for mining (Announcement No.: CN219159963U) has at least the following disadvantages: the device uses a T-shaped slide rail to make the slider slide on the T-shaped slide rail to complete the adjustment of the camera angle. However, since the slider is fixed by the friction generated by the locking bolt against the T-shaped slide rail, and the inside of the mine tunnel often generates vibrations due to operations such as excavation, this can easily cause the locking bolt to loosen due to the vibration. If the locking bolt is slightly loose, the locking force between the locking bolt and the T-shaped slide rail will be insufficient, resulting in insufficient friction between the locking bolt and the T-shaped slide rail, causing the slider to slide on the T-shaped slide rail, resulting in a deviation in the camera angle of the camera, resulting in insufficient reliability of the device, and therefore the present utility model is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a mine-used intrinsically safe thermal imaging camera.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A mine-use intrinsically safe thermal imaging camera comprises a mounting plate, a camera body is arranged on one side of the mounting plate, an adjustment assembly is arranged below the camera body, the adjustment assembly comprises a first rotating seat fixed on one side of the mounting plate near the bottom surface, a threaded sleeve is fixed on the outer wall of a rotating rod of the first rotating seat, a screw is connected to the inner thread of the threaded sleeve, a second rotating seat is connected to the bottom surface of the camera body, a fixing rod is rotatably connected to the top end of the screw, the top end of the fixing rod is fixed to the outer wall of the rotating rod of the second rotating seat, a locking nut is threadedly connected to the outer wall of the screw, and the locking nut is tightly in contact with an end of the threaded sleeve near the screw.

[0007] As a further solution of the utility model, a third rotating seat is fixed on one side of the mounting plate near the top surface, the camera body is connected to one side of the rotating rod of the third rotating seat, a fixing ring is fixed to the outer wall of the threaded sleeve, a tension spring is fixed to the top surface of the fixing ring, a movable ring is fixed to the top of the tension spring, the tension spring and the movable ring are both movably mounted on the outer wall of the threaded sleeve, and the movable ring is connected to the locking nut.

The top surface of the locking nut is provided with four connecting grooves, and the four connecting grooves are arranged in a circular array with the center of the locking nut as the center.

[0009] As a further solution of the utility model, a rotating nut is fixed to the outer wall of the screw rod, and the length from the top surface of the rotating nut to the top end of the screw rod is one third of the length of the screw rod.

[0023] like Figure 2-Figure 4 As shown, in this embodiment, a third rotating seat 204 is fixed to one side of the mounting plate 1 near the top surface, the camera body 101 is connected to one side of the rotating rod of the third rotating seat 204, a fixing ring 205 is fixed to the outer wall of the threaded sleeve 201, a tension spring 206 is fixed to the top surface of the fixing ring 205, a movable ring 207 is fixed to the top of the tension spring 206, the tension spring 206 and the movable ring 207 are both movably sleeved on the outer wall of the threaded sleeve 201, and the movable ring 207 is connected to the locking nut 209. By adopting the third rotating seat 204 to connect the rear side of the camera body 101 to the mounting plate 1, the staff can adjust the camera When adjusting the angle of the main body 101, it is only necessary to rotate the screw rod 202 and adjust the total length of the screw rod 202 and the threaded sleeve 201 to achieve the angle adjustment of the camera main body 101. The adjustment process is simple and fast. After the adjustment, the locking nut 209 is used to tighten the connection between the screw rod 202 and the threaded sleeve 201, and then the tension spring 206 is used to pull the screw rod 202 and the locking nut 209 in the direction of the threaded sleeve 201, thereby effectively increasing the tightness of the threaded connection between the screw rod 202 and the threaded sleeve 201, making it difficult for the camera main body 101 to rotate when it is vibrated inside the mine tunnel, thereby increasing the reliability of the device.

[0024] like Figure 2-Figure 4 As shown, in this embodiment, the top surface of the movable ring 207 is rotatably connected with four connecting blocks 3, and the four connecting blocks 3 are arranged in a circular array with the center of the movable ring 207 as the center. The top surface of the locking nut 209 is provided with four connecting grooves 301, and the four connecting grooves 301 are arranged in a circular array with the center of the locking nut 209 as the center. By setting the connecting blocks 3 and the connecting grooves 301, the connecting blocks 3 and the connecting grooves 301 are inserted into the inside of the connecting blocks 3 and the connecting grooves 301, so that the movable ring 207 and the locking nut 209 can be connected, so that the tension spring 206 applies tension to the screw rod 202 and the locking nut 209.

[0025] like Figure 2-Figure 4 As shown, in this embodiment, a rotating nut 4 is fixed to the outer wall of the screw rod 202, and the length from the top surface of the rotating nut 4 to the top of the screw rod 202 is one third of the length of the screw rod 202. By providing the rotating nut 4, the staff can use tools such as wrenches to rotate the screw rod 202 to adjust the shooting angle of the camera body 101.

[0026] like Figure 2-Figure 4As shown, in this embodiment, the second rotating seat 203 is detachably mounted on the bottom surface of the camera body 101 by bolts, and the third rotating seat 204 is detachably mounted on the rear side of the camera body 101 by bolts. By arranging that the second rotating seat 203 and the third rotating seat 204 are detachably mounted on the camera body 101 by bolts, when the camera body 101 needs to be inspected, it can be directly removed separately, and there is no need to adjust the shooting angle of the camera body 101 when it is subsequently installed.

[0027] like Figure 2-Figure 4 As shown, in this embodiment, mounting holes 5 are provided at four corners of one side of the mounting plate 1, and expansion bolts 501 are inserted into the mounting holes 5. By providing the mounting holes 5 and inserting the expansion bolts 501 into the mounting holes 5, the expansion bolts 501 are fixed to the mine tunnel wall, and the mounting plate 1 can be fixed to the mine tunnel wall.

[0028] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: in use, by setting the mounting hole 5, inserting the expansion bolt 501 inside the mounting hole 5, so that the expansion bolt 501 is fixed to the mine wall, the mounting plate 1 can be fixed to the mine wall, and then the camera body 101 is respectively installed on the second rotating seat 203 and the third rotating seat 204 by using bolts, and then the rotating nut 4 is rotated using a tool such as a wrench to make the screw rod 202 rotate inside the threaded sleeve 201, so as to adjust the total length of the screw rod 202 and the threaded sleeve 201, and the angle of the camera body 101 can be adjusted. After adjusting the angle of the camera body 101, the locking nut 209 is rotated using a tool such as a wrench so that the locking nut 209 is close to the threaded sleeve 201. The end of the near screw rod 202 is tightly in contact, and the locking nut 209 now makes the connection between the screw rod 202 and the threaded sleeve 201 more tightly, and then the movable ring 207 is pulled. At this time, the tension spring 206 is in a stretched state, and the movable ring 207 is stretched to the top of the locking nut 209, and then the connecting block 3 is rotated to make it correspond to the position of the connecting groove 301. At this time, the movable ring 207 is loosened, and the tension spring 206 rebounds to drive the movable ring 207 to move downward, and the connecting block 3 is inserted into the connecting groove 301. At this time, the tension spring 206 pulls the screw rod 202 and the locking nut 209 toward the direction of the threaded sleeve 201, thereby effectively increasing the tightness of the threaded connection between the screw rod 202 and the threaded sleeve 201, making it difficult for the camera body 101 to rotate when it is vibrated inside the mine tunnel, thereby increasing the reliability of the device.
