Description

Technical Field

[0001] This utility model relates to the field of safety monitoring technology, and in particular to an early warning device for coal mine goaf collapse. Background Technology

[0002] Coal mine goaf collapse early warning devices are specialized equipment designed to prevent collapse accidents in coal mine goaf areas. These devices can provide early warnings of collapse risks by monitoring and analyzing various geological and engineering parameters, thereby ensuring the safety of personnel and property.

[0003] Existing coal mine goaf collapse early warning devices are susceptible to damage from collisions, compression, or vibrations during transportation from one coal mine to another due to the lack of a protective enclosure. This damage can affect the accuracy and reliability of the early warning device, increasing maintenance costs and time. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing coal mine goaf collapse early warning devices suffer from a lack of protection during transportation, which may lead to damage to electronic components and sensors, affecting the accuracy and reliability of the device and increasing maintenance costs and time. Therefore, we propose a coal mine goaf collapse early warning device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a coal mine goaf collapse early warning device, comprising a storage box, an adjustment groove at one end of the storage box, a hollow block fixedly connected to the bottom of the inner cavity of the storage box, a connecting rod slidably connected inside the hollow block, a placement frame fixedly connected to the top of the connecting rod, a cover plate fixedly connected to the top of the placement frame, an early warning device installed inside the placement frame, a handle fixedly connected to the top of the cover plate, two slots at one end of the hollow block, a slot at one end of the connecting rod, a thrust spring fixedly connected inside the slot, and a pressing block fixedly connected to one end of the thrust spring.

[0006] Preferably, sliding grooves are provided on both sides of the inner cavity of the slot, and sliders are fixedly connected to both sides of the push block.

[0007] Preferably, the surface of the button is slidably connected to the interior of the slot, and the outer shape of the button matches the inner shape of the slot.

[0008] Preferably, limit grooves are provided on both sides of the inner cavity of the hollow block, and limit blocks are fixedly connected to both sides of the connecting rod.

[0009] Preferably, a buffer spring is fixedly connected to the bottom of the inner cavity of the hollow block, and a buffer plate is fixedly connected to the top of the buffer spring.

[0010] Preferably, threaded holes are provided on both sides of the placement frame, and a threaded rod is rotatably connected inside the threaded hole, with a circular plate fixedly connected to one side of the threaded rod.

[0011] Preferably, an anti-slip pad is fixedly connected to one side of the circular plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator presses the button, causing the push spring to retract into the slot. Then, by moving the connecting rod downwards, the connecting rod moves the placement frame and the warning device downwards until the warning device is completely stored inside the storage box. When the button moves to the position corresponding to the slot at the bottom of one end of the hollow block, the spring force pushes the button into the slot, thereby limiting the connecting rod and ensuring that the warning device is stably fixed inside the storage box. This allows the operator to conveniently store and secure the warning device. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a coal mine goaf collapse early warning device, including a storage box 1, an adjustment groove 2 at one end of the storage box 1, a hollow block 3 fixedly connected to the bottom of the inner cavity of the storage box 1, a connecting rod 4 slidably connected inside the hollow block 3, a placement frame 5 fixedly connected to the top of the connecting rod 4, a cover plate 22 fixedly connected to the top of the placement frame 5, an early warning device 6 installed inside the placement frame 5, a handle 7 fixedly connected to the top of the cover plate 22, two slots 8 at one end of the hollow block 3, a slot 9 at one end of the connecting rod 4, a thrust spring 10 fixedly connected inside the slot 9, and a... By pressing the button 11, the operator causes the push spring 10 to retract into the slot 9. Then, by moving the connecting rod 4 downward, the placing frame 5 and the warning device 6 move downward until the warning device 6 is completely retracted into the storage box 1. When the button 11 moves to the position corresponding to the slot 8 at the bottom of one end of the hollow block 3, the push spring 10 pushes the button 11 into the slot 8, thereby limiting the connecting rod 4 and ensuring that the warning device 6 can be stably fixed inside the storage box 1. This allows the operator to easily store and fix the warning device 6.

[0022] Reference Figure 3 As shown in this embodiment: both sides of the inner cavity of the slot 9 are provided with sliding grooves 12, and both sides of the button 11 are fixedly connected with sliders 13. By setting the sliding grooves 12 and sliders 13, the movement trajectory of the button 11 can be limited to prevent the button 11 from deviating during the movement, which would affect the stability of the button 11 when it is inserted into the slot 8. At the same time, the button 11 can be supported, which improves the stability of the button 11 when it moves.

[0023] Reference Figure 2 and Figure 3 As shown in this embodiment: the surface of the button 11 is slidably connected to the inside of the slot 8, and the outer shape of the button 11 matches the inner shape of the slot 8. By sliding the surface of the button 11 to the inside of the slot 8 and matching the outer shape of the button 11 to the inner shape of the slot 8, the button 11 can be smoothly inserted into the inside of the slot 8, effectively limiting the connecting rod 4 and improving the stability of the early warning device 6 fixed inside the storage box 1.

[0024] Reference Figure 2As shown in this embodiment: Limiting grooves 14 are opened on both sides of the inner cavity of the hollow block 3, and limiting blocks 15 are fixedly connected to both sides of the connecting rod 4. By setting the limiting grooves 14 and limiting blocks 15, the connecting rod 4 can be limited to prevent the connecting rod 4 from shaking during the movement, which would reduce the stability of the early warning device 6 fixed inside the storage box 1. At the same time, the connecting rod 4 can be supported, which improves the stability of the connecting rod 4 when it moves.

[0025] Reference Figure 4 As shown in this embodiment: a buffer spring 16 is fixedly connected to the bottom of the inner cavity of the hollow block 3, and a buffer plate 17 is fixedly connected to the top of the buffer spring 16. By setting the buffer spring 16 and the buffer plate 17, the connecting rod 4 can be effectively buffered when falling, preventing the connecting rod 4 from directly impacting the bottom of the inner cavity of the hollow block 3 when falling, thus preventing damage to the connecting rod 4.

[0026] Reference Figure 5 As shown in this embodiment: threaded holes 18 are provided on both sides of the placement frame 5. A threaded rod 19 is rotatably connected inside the threaded hole 18. A circular plate 20 is fixedly connected to one side of the threaded rod 19. Through the setting of the threaded hole 18, the threaded rod 19 and the circular plate 20, the warning device 6 can be fixed to prevent the warning device 6 from shaking inside the placement frame 5, which would cause the warning device 6 to fall off during use and cause damage to the warning device 6, thus improving the stability of the warning device 6 inside the placement frame 5.

[0027] Reference Figure 5 As shown in this embodiment: an anti-slip pad 21 is fixedly connected to one side of the circular plate 20. The configuration of the anti-slip pad 21 increases the friction when the circular plate 20 comes into contact with the early warning device 6, preventing the circular plate 20 from sliding and causing relative displacement with the early warning device 6 during rotation.

[0028] Working principle: By pressing the button 11, the operator causes the push spring 10 to retract into the slot 9. Then, by moving the connecting rod 4 downwards, the placement frame 5 and the warning device 6 move downwards until the warning device 6 is completely retracted into the storage box 1. When the button 11 moves to the position corresponding to the slot 8 at the bottom of one end of the hollow block 3, the spring force of the push spring 10 pushes the button 11 into the slot 8, thus limiting the connection rod 4 and stably fixing the warning device 6 inside the storage box 1. The system allows operators to easily store and secure the warning device 6, preventing damage when not in use. The sliding groove 12 and slider 13 limit the movement trajectory of the button 11, preventing it from shifting during movement and affecting its stability when inserted into the slot 8. They also provide support, improving the stability of the button 11 during movement. The sliding connection between the surface of the button 11 and the interior of the slot 8, along with the matching shape of the button 11 to the interior of the slot 8, ensures the button 11 can smoothly engage in the slot. Inside the housing 8, the connecting rod 4 is effectively limited, improving the stability of the warning device 6 fixed inside the storage box 1. The limiting groove 14 and limiting block 15 limit the connecting rod 4, preventing it from wobbling during movement and reducing the stability of the warning device 6 inside the storage box 1. They also support the connecting rod 4, improving its stability during movement. The buffer spring 16 and buffer plate 17 effectively cushion the connecting rod 4 during descent, preventing it from impacting the inner cavity of the hollow block 3. A direct impact at the bottom damages the connecting rod 4. The threaded hole 18, threaded rod 19, and circular plate 20 can fix the warning device 6, preventing it from shaking inside the placement frame 5 and falling off during use, thus improving its stability. The anti-slip pad 21 increases friction when the circular plate 20 contacts the warning device 6, preventing relative displacement between the circular plate 20 and the warning device 6 during rotation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
