Technical Field

[0001] The utility model relates to the technical field of sensors, and specifically relates to an explosion-proof inclination sensor. Background Art

[0002] An inclination sensor, also known as an inclinometer or tilt meter, is commonly used for measuring the horizontal angle change of a system and is widely applied in fields such as bridge erection, railway laying, oil drilling, and machining. During coal mine mining, the inclination sensor can be used to measure the mining angle of the coal mine roadway, monitor the inclination degree of the roadway, ensure the stability of the roadway, and prevent the collapse of the roadway roof.

[0003] Currently, most of the existing inclination sensors for coal mine roadways are installed at fixed points, so only fixed-point monitoring can be carried out. However, there is a certain distance along the "radial" direction of the coal mine roadway roof, and the fixed-point monitoring range is limited. It is impossible to quickly and widely monitor the real-time dynamics of the roadway roof, so it is impossible to timely monitor the possible collapse and give an alarm in time. Therefore, an inclination sensor is needed to widely monitor the roadway roof. Summary of the Utility Model

[0004] In view of the above problems, the present application provides an explosion-proof inclination sensor. Based on the traditional explosion-proof inclination sensor, the structure is optimized and designed, and an installation structure is provided for it, enabling it to move horizontally back and forth along the roof of the coal mine roadway. At the same time, the horizontal installation position of the explosion-proof inclination sensor can be adjusted at any time, expanding the monitoring range and ensuring the timeliness of collapse warning.

Specific embodiments

[0023] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the present utility model in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model.

[0024] As Figure 1-Figure 5 shown, an explosion-proof inclination sensor includes a U-shaped frame 1, a strip-shaped installation groove 2, an electric slider 3, a C-shaped plate 4, an installation component 5, and an inclination sensor body 6. The inclination sensor body 6 is arranged at the upper end of the installation component 5, the installation component 5 is arranged in the middle of the C-shaped plate 4, the C-shaped plate 4 has an upward opening, and the upper ends of both sides of the C-shaped plate 4 are fixedly connected with electric sliders 3. The electric sliders 3 are slidably installed inside the strip-shaped installation groove 2, and the strip-shaped installation grooves 2 are symmetrically opened at the lower ends of both sides of the U-shaped frame 1.

[0025] The U-shaped frame 1 is symmetrically hinged with support rods 11 near the ends of both sides, and the ends of the support rods 11 away from the U-shaped frame 1 are fixedly connected with side plates 12.

[0026] During specific operation, installation holes are opened at the corners of the side plate 12, and the side plate 12 is manually fixed and installed on the side wall of the coal mine roadway. At the same time, the upper end of the U-shaped frame 1 is in contact with the top of the coal mine roadway. During the normal operation of the inclination sensor body 6, the support rods 11 can play a certain supporting role for the U-shaped frame 1, and the U-shaped frame 1 can play a certain supporting role for the top of the coal mine roadway, thereby reducing the possibility of its collapse.

[0027] The described mounting assembly 5 includes internal threaded holes 51. The bottom of the U-shaped plate 4 is provided with internal threaded holes 51 arranged linearly. A screw rod 52 is screwed into the internal threaded hole 51. The lower end of the screw rod 52 is fixedly connected with a nut 53. The upper end of the nut 53 is rotatably connected with a connecting block 54. The upper end of the connecting block 54 is fixedly connected with a mounting plate 55.

[0028] In the middle of the upper end face of the described mounting plate 55, a ball head rod 551 is fixedly arranged. The upper end of the ball head rod 551 is ball-jointed in the middle of the lower end of the inclination sensor body 6. A support spring 552 is sleeved on the ball head rod 551 between the mounting plate 55 and the inclination sensor body 6. A dust-proof film 553 is arranged outside the support spring 552. The upper end of the dust-proof film 553 is fixedly connected to the lower end face of the inclination sensor body 6. The lower end of the dust-proof film 553 is fixedly connected to the upper end face of the mounting plate 55.

[0029] During specific operation, before the inclination sensor body 6 is used, manually rotate the nut 53 to drive the screw rod 52 to rotate at the same time. At this time, while the screw rod 52 rotates, it drives the mounting plate 55 to move up or down, so as to adjust the mounting plate 55 and the inclination sensor body 6 to a horizontal state.

[0030] The described inclination sensor body 6 is an SST810 type dynamic explosion-proof sensor. In the middle of the upper end of the inclination sensor body 6, a pressure-bearing block 61 is fixedly arranged. Wings 62 are symmetrically connected to both sides of the pressure-bearing block 61. The upper end faces of the pressure-bearing block 61, the wings 62 and the upper end face of the loop-shaped frame body 1 are at the same horizontal height.

[0031] During specific operation, after the inclination sensor body 6 is adjusted to a horizontal state, the upper end faces of the pressure-bearing block 61 and the wings 62 will contact the top of the coal mine roadway. At this time, drive the U-shaped plate 4 to move left and right reciprocally through the electric slider 3, so as to drive the mounting assembly 5 and the inclination sensor body 6 to move reciprocally along the strip-shaped mounting groove 2. During this process, the inclination sensor body 6 can monitor the top of the coal mine roadway. If the top collapses, the top soil will exert extrusion on the pressure-bearing block 61 and the wings 62. This extrusion force will cause the inclination sensor body 6 to deviate around the upper end of the ball head rod 551, and the support spring 552 will be laterally compressed. At this time, the inclination sensor body 6 can monitor the collapse signal of the top of the coal mine roadway and give an alarm in time, and the wings 62 can support the collapsed part, so as to facilitate manual response in time.

[0032] Working principle: The corners of the side plate 12 are provided with mounting holes, and the side plate 12 is manually fixedly mounted on the side wall of the coal mine tunnel, and the upper end of the circular frame 1 is in contact with the top of the coal mine tunnel. During the normal operation of the inclination sensor body 6, the support rod 11 can play a certain supporting role on the circular frame 1, and the circular frame 1 can play a certain supporting role on the top of the coal mine tunnel, thereby reducing the possibility of its collapse;

[0033] Then, the nut 53 is manually rotated to drive the screw rod 52 to rotate, and the screw rod 52 drives the mounting plate 55 to move upward or downward while rotating, so that the mounting plate 55 and the inclination sensor body 6 are adjusted to a horizontal state;

[0034] After the inclination sensor body 6 is adjusted to a horizontal state, the upper end surfaces of the pressure block 61 and the fender 62 will contact the top of the coal mine tunnel. At this time, the electric slider 3 drives the shaped plate 4 to reciprocate left and right, thereby driving the installation assembly 5 and the inclination sensor body 6 to reciprocate along the strip installation groove 2. During this process, the inclination sensor body 6 can monitor the top of the coal mine tunnel. If the top collapses, the top soil will squeeze the pressure block 61 and the fender 62. The squeezing force will cause the inclination sensor body 6 to deviate around the upper end of the ball head rod 551, and the support spring 552 will be laterally compressed. At this time, the inclination sensor body 6 can monitor the collapse signal at the top of the coal mine tunnel and alarm in time, and the fender 62 can support the collapsed part, so as to facilitate timely manual response.

[0035] It is worth noting that when the pressure block 61 and the fender 62 are separated from the collapsed position, the reaction force of the support spring 552 will drive the inclination sensor body 6 to return to a horizontal state.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
