Description

Technical Field

[0001] This utility model belongs to the technical field of mining measuring instruments, specifically relating to an intrinsically safe height measuring sensor for mining. Background Technology

[0002] In the mining process, accurately measuring the height of spaces such as roadways and mining areas is of great significance for safe production and resource management. Traditional height measurement methods, such as using measuring tapes and levels, suffer from problems such as cumbersome operation, low accuracy, and low efficiency.

[0003] With the development of electronic technology, mine height measurement sensors generally use laser rangefinders or ultrasonic sensors for height measurement. However, these sensors have some limitations in the application of special mining environments, such as insufficient protection performance and poor anti-interference ability, which affect the service life of the sensors. Since the sensors need to be installed with the probe facing upwards, dust generated during laser mining operations can easily cover the sensors, causing interference and affecting the sensor's performance. Utility Model Content

[0004] The purpose of this invention is to provide an intrinsically safe height measuring sensor for mining applications to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intrinsically safe height measuring sensor for mining, comprising a base, a laser rangefinder, a protective cover, and a cleaning assembly. The laser rangefinder is fixedly mounted on the base, and buckles are fixedly mounted on all four sides of the base. The protective cover is fixedly mounted on the base via buckles, and the laser rangefinder is disposed inside the protective cover. A tempered glass sheet is embedded in the top of the protective cover.

[0006] The cleaning assembly includes a movable frame that slides on top of the protective cover and a sponge block that is fixedly mounted on the movable frame. A screw is rotatably mounted on one side of the protective cover. One end of the movable frame is sleeved on the screw and threadedly connected to the screw. A motor for driving the screw to rotate is fixedly mounted on the surface of the protective cover.

[0007] In a preferred embodiment, mounting holes are provided at all four corners of the base.

[0008] In a preferred embodiment, a guide rod is fixedly installed on the side of the protective cover away from the screw, and the other end of the movable frame is slidably sleeved on the guide rod.

[0009] In a preferred embodiment, the protective cover has grooves on both sides, and the screw and guide rod are both disposed in the grooves.

[0010] In a preferred embodiment, a connecting plate is fixedly connected to the top of the sponge block, a positioning bolt is inserted into the top of the movable frame, and the connecting plate is fixedly installed at the bottom of the movable frame by the positioning bolt.

[0011] In a preferred embodiment, a T-shaped block is provided at the top of both ends of the connecting plate, and a positioning hole adapted to the positioning bolt is opened at the top of the T-shaped block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This intrinsically safe height sensor for mining uses a protective cover. When the laser rangefinder is working, the protective cover can be placed on the base to cover and protect the laser rangefinder. At the same time, the tempered glass sheet protects the laser probe of the laser rangefinder, improving the sensor's protection performance and extending its service life.

[0014] This intrinsically safe height sensor for mining uses a cleaning component. When dust covers the tempered glass plate of the protective cover, the motor can be started to drive the screw to rotate. The screw drives the movable frame to slide along the guide rod, and the movable frame drives the sponge block to clean the dust on the tempered glass plate, thus preventing dust from interfering with the sensor and ensuring the sensor's performance.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides an intrinsically safe height measuring sensor for mining, including a base 1, a laser rangefinder 2, a protective cover 3, and a cleaning component 4. Mounting holes 12 are provided at each of the four corners of the base 1, allowing the base 1 to be fixed to the ground or a support. The laser rangefinder 2 is fixedly mounted on the base 1. Buckles 11 are fixedly installed around the base 1. The protective cover 3 is fixedly mounted on the base 1 via the buckles 11. The laser rangefinder 2 is housed inside the protective cover 3. A tempered glass sheet 31 is embedded in the top of the protective cover 3. When the laser rangefinder 2 is working, the protective cover 3 can cover the base 1, providing protection for the laser rangefinder 2. Simultaneously, the tempered glass sheet 31 protects the laser probe of the laser rangefinder 2, improving the sensor's protective performance and extending its service life.

[0022] Reference Figure 1 and Figure 2 The cleaning component 4 includes a movable frame 41 slidably mounted on the top of the protective cover 3 and a sponge block 42 fixedly mounted on the movable frame 41. A screw 43 is rotatably mounted on one side of the protective cover 3. One end of the movable frame 41 is sleeved on the screw 43 and threadedly connected to the screw 43. A motor 44 for driving the screw 43 to rotate is fixedly mounted on the surface of the protective cover 3. A guide rod 45 is fixedly mounted on the side of the protective cover 3 away from the screw 43. The other end of the movable frame 41 is slidably sleeved on the guide rod 45. With the cleaning component 4, when dust covers the tempered glass plate 31 of the protective cover 3, the motor 44 can be started to drive the screw 43 to rotate, so that the screw 43 drives the movable frame 41 to slide along the guide rod 45, so that the movable frame 41 drives the sponge block 42 to clean the dust on the tempered glass plate 31, avoiding dust interference with the sensor and ensuring the sensor's performance.

[0023] The protective cover 3 has grooves 32 on both sides, and the screw 43 and guide rod 45 are both set in the grooves 32. The grooves 32 can be used to store and protect the screw 43 and guide rod 45, reducing the interference of the screw 43 and guide rod 45 from the outside.

[0024] Specifically, refer to Figure 3 A connecting plate 46 is fixedly connected to the top of the sponge block 42, and a positioning bolt 47 is inserted into the top of the movable frame 41. The connecting plate 46 is fixedly installed at the bottom of the movable frame 41 by the positioning bolt 47. T-shaped blocks 48 are provided at the top of both ends of the connecting plate 46. The top of the T-shaped blocks 48 is provided with positioning holes 49 that are compatible with the positioning bolts 47. The setting of the connecting plate 46, positioning bolts 47, T-shaped blocks 48 and positioning holes 49 makes it convenient to disassemble and replace the sponge block 42, ensuring the performance of the sponge block 42.

[0025] The working principle and usage process of this utility model are as follows: First, by setting up the protective cover 3, when the laser rangefinder sensor 2 is working, the protective cover 3 can be placed on the base 1 to cover and protect the laser rangefinder sensor 2. At the same time, the tempered glass plate 31 protects the laser probe of the laser rangefinder sensor 2, improving the protection performance of the sensor and extending its service life. By setting up the cleaning component 4, when dust covers the tempered glass plate 31 of the protective cover 3, the motor 44 can be started to drive the screw 43 to rotate, so that the screw 43 drives the movable frame 41 to slide along the guide rod 45, so that the movable frame 41 drives the sponge block 42 to clean the dust on the tempered glass plate 31, avoiding dust interference with the sensor and ensuring the sensor's performance.
