Description

Technical Field

[0001] This utility model relates to the field of temperature measuring instrument technology, and in particular to a temperature measuring device for use in dusty environments in open-pit coal mines. Background Technology

[0002] An open-pit coal mine is a type of mine that extracts coal resources by excavating large pits on the surface. Unlike underground coal mines, the ore seams in an open-pit mine are exposed on the surface and can be mined directly. Open-pit mines are typically used for mining coal resources with relatively shallow seams and large areas. Temperature monitoring is a crucial safety measure during open-pit coal mining. It not only helps ensure smooth mining operations and reduces the risk of accidents but also improves work efficiency and protects the safety of workers and equipment.

[0003] In existing open-pit coal mines, temperature measuring devices often accumulate dust on their lenses during long-term use due to the high dust levels in the working environment. This dust buildup can affect the normal operation of the temperature measuring device, reduce the sensing accuracy of the lens, and thus cause temperature detection errors.

[0004] Therefore, we propose a temperature measuring device for dusty environments in open-pit coal mines. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a temperature measuring device for dusty environments in open-pit coal mines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature measuring device for dusty environments in open-pit coal mines, comprising a temperature measuring instrument body and a detection lens body. A fixing box is fixedly installed on the front wall of the temperature measuring instrument body. A convex block is provided inside the fixing box. A driving mechanism for moving the convex block is provided on the right outer wall of the fixing box. The driving mechanism includes a drive motor and a threaded rod. A push rod is fixedly installed on the side wall of the convex block near the detection lens body. A mounting block is fixedly connected to the other end of the push rod. A cleaning plate is provided on the mounting block. A cleaning sponge for cleaning the detection lens body is fixedly connected to the rear wall of the cleaning plate. An installation groove is opened on the front wall of the mounting block. Two push plates are slidably arranged in the installation groove. A disassembly and assembly component for disassembling and assembling the cleaning plate is provided on the two push plates. The disassembly and assembly component includes a telescopic rod, a return spring, and two positioning rods.

[0007] As a preferred embodiment of this utility model, the drive motor is fixedly installed on the right outer wall of the fixed box, the right end of the threaded rod passes through the fixed box and is fixedly fitted onto the left output end of the drive motor, the left end of the threaded rod is movably fitted onto the left inner wall of the fixed box, and the threaded rod passes through the lower end of the convex block and is threadedly connected to the convex block.

[0008] As a preferred technical solution of this utility model, a sliding rod is fixedly connected between the inner walls of the left and right sides of the fixing box. The sliding rod and the threaded rod are arranged vertically. The sliding rod passes through the convex block and is slidably connected to the upper end of the convex block.

[0009] As a preferred embodiment of this utility model, the end of the push rod away from the convex block passes through the fixed box and is slidably connected to the fixed box.

[0010] As a preferred embodiment of this utility model, the two push plates are located on the upper and lower sides of the mounting groove, respectively, and the two ends of the telescopic rod are fixedly connected to the opposite end wall of the two push plates, with the reset spring sleeved on the outside of the telescopic rod.

[0011] As a preferred technical solution of this utility model, the two positioning rods are fixedly connected to the wall surfaces of the two push plates at opposite ends, with the other ends of the two positioning rods passing through the mounting block and slidably connected to the mounting block.

[0012] As a preferred technical solution of this utility model, the front wall of the cleaning plate is provided with a slot adapted to the mounting block, and the upper and lower side walls of the inner cavity of the slot are respectively provided with two positioning holes, and the two positioning holes are adapted to two positioning rods respectively.

[0013] This utility model provides a temperature measuring device for dusty environments in open-pit coal mines. It has the following beneficial effects:

[0014] 1. This temperature measuring device for dusty environments in open-pit coal mines, when in use, starts the drive motor, which drives the threaded rod to rotate, thereby moving the convex block to the left. The leftward movement of the convex block causes the push rod, mounting block, cleaning plate, and cleaning sponge to move to the left together, so that the cleaning sponge comes into contact with the surface of the detection lens body to clean the surface dust, thus avoiding the phenomenon of temperature measurement error caused by the accumulation of a large amount of dust in the detection lens. As the cleaning sponge is used for a long time, its cleaning effect gradually decreases. At the same time, it pushes the two push plates, causing them to move closer to each other and squeeze the telescopic rod and the return spring, providing sufficient space for the two positioning rods. In this way, the two positioning rods will move out of the positioning holes, making it convenient to replace the cleaning plate and cleaning sponge. This design is simple, reasonable, and highly practical.

[0015] 2. This temperature measuring device for dusty environments in open-pit coal mines uses a sliding rod design to limit the movement of the convex block, preventing it from rotating and ensuring more stable movement. Attached Figure Description

A fixing box 12 is fixedly installed on the front wall of the thermometer body 10. A convex block 13 is provided inside the fixing box 12. A drive mechanism for moving the convex block 13 is provided on the right outer wall of the fixing box 12. The drive mechanism includes a drive motor 14 and a threaded rod 15. A push rod 17 is fixedly installed on the side wall of the convex block 13 near the probe lens body 11. The other end of the push rod 17 is fixedly connected to a mounting block 18. A cleaning plate 19 is provided on the mounting block 18. The rear of the cleaning plate 19... A cleaning sponge 20 for cleaning the probe lens body 11 is fixedly connected to the end wall. A mounting groove 21 is provided on the front wall of the mounting block 18. Two push plates 22 are slidably arranged in the mounting groove 21. The two push plates 22 are equipped with a disassembly / reassembly assembly for disassembling the cleaning plate 19. The disassembly / reassembly assembly includes a telescopic rod 23, a return spring 24, and two positioning rods 25. The drive motor 14 is fixedly mounted on the right outer wall of the fixing box 12. The right end of the threaded rod 15 passes through the fixing box 12 and is fixedly fitted onto the left output end of the drive motor 14. The left end of rod 15 is movably sleeved on the left inner wall of the fixed box 12, and the threaded rod 15 passes through the lower end of the convex block 13 and is threadedly connected to the convex block 13. A sliding rod 16 is fixedly connected between the left and right inner walls of the fixed box 12. The sliding rod 16 and the threaded rod 15 are arranged vertically. The sliding rod 16 passes through the convex block 13 and is slidably connected to the upper end of the convex block 13. The end of the push rod 17 away from the convex block 13 passes through the fixed box 12 and is slidably connected to the fixed box 12. Two push plates 22 are located on the upper and lower sides of the mounting groove 21, respectively. The two ends of the telescopic rod 23 are fixedly connected to... On the opposite end wall of the two push plates 22, the return spring 24 is sleeved on the outside of the telescopic rod 23.

[0024] The working principle of this utility model is as follows: When in use, the drive motor 14 is started, which drives the threaded rod 15 to rotate. Through the cooperation of the slide rod 16, the convex block 13 is moved to the left. The leftward movement of the convex block 13 causes the push rod 17, the mounting block 18, the cleaning plate 19, and the cleaning sponge 20 to move to the left together. Thus, the cleaning sponge 20 comes into contact with the surface of the detection lens body 11 to clean the surface dust, thereby avoiding the phenomenon of temperature measurement error caused by the accumulation of a large amount of dust in the detection lens. As the cleaning sponge 20 is used for a long time, its cleaning effect gradually decreases. At the same time, it pushes the two push plates 22, causing them to move closer to each other and squeeze the telescopic rod 23 and the return spring 24, providing sufficient space for the two positioning rods 25. In this way, the two positioning rods 25 will move out of the positioning hole 27, making it convenient to replace the cleaning plate 19 and the cleaning sponge 20. This design is simple, reasonable, and highly practical.
