Description
Technical Field
[0001] This utility model relates to the field of geological disaster monitoring technology, and in particular to a protective device for geological disaster monitoring facilities in confined spaces. Background Technology
[0002] Landslides, mudslides, and debris flows pose a significant threat to people's lives and property. To mitigate the threats and damage caused by geological disasters, geological disaster monitoring and early warning technologies are constantly evolving. In geological disaster monitoring, monitoring the geological conditions in confined spaces (such as deep fissures and narrow mine shafts) is crucial. However, existing geological disaster monitoring facilities, once installed in confined spaces, are often susceptible to collisions and compression due to space limitations. Furthermore, harsh environments such as rainfall and rockfalls can easily damage the monitoring equipment, affecting the accuracy of monitoring data and the lifespan of the equipment. Therefore, protective devices need to be installed on the outside of the monitoring facilities for protection.
[0003] Traditional monitoring facility protection devices typically involve installing numerous protective frames on the outside of the monitoring facility to form partitions and protect it. However, these partitions can only isolate large falling rocks and animals, and are not very effective at protecting against small falling rocks and rainwater. Fully enclosed partitions, on the other hand, can affect the monitoring effect and also have an impact on some monitoring facilities that rely on natural energy sources such as solar power for power generation. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a protective device for geological disaster monitoring facilities in narrow spaces, aiming to improve the problems of poor protection against small falling rocks and rainwater by the interval partitions of existing monitoring facility protection devices, and the fact that fully enclosed partitions will affect the monitoring effect.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a protective device for geological disaster monitoring facilities in confined spaces, comprising a base plate 1 and multiple long rods 3, wherein multiple horizontal columns 4 are fixedly connected to opposite sides of two long rods 3, and connecting blocks 5 are fixedly connected to both ends of each long rod 3. A motor 7 is fixedly connected to the inner wall of one of the connecting blocks 5, and a lead screw 8 is fixedly connected to the output end of the motor 7. A slider 9 is slidably connected to the inner wall of the long rod 3, and a traction rod 10 is fixedly connected to opposite sides of two sliders 9. The outer wall of the traction rod 10... A protective curtain 11 is provided. A rotating column 12 is rotatably connected to the inner wall of one of the connecting blocks 5. A coil spring 13 is provided on the outer wall of the rotating column 12. A turntable 14 is fixedly connected to the outer wall of the rotating column 12. A winding column 15 is fixedly connected to the outer wall of the turntable 14. An opening and closing assembly is provided at the top of the base plate 1. One end of the coil spring 13 is fixedly connected to the inner wall of the connecting block 5. The other end of the coil spring 13 is fixedly connected to the outer wall of the rotating column 12. The turntable 14 is slidably connected to the inner wall of the connecting block 5. The protective curtain 11 is sleeved on the outer wall of the winding column 15.
[0029] Specifically, the device is installed outside the monitoring facility. When a geological disaster or rainfall occurs, the motor 7 is activated, causing the lead screw 8 to rotate. This, in turn, causes the two sliders 9 and the traction rod 10 between the two sliders 9 to slide. When the traction rod 10 slides, it pulls the protective curtain 11 to open. In its default state, the protective curtain 11 is rolled up on the winding column 15. When the protective curtain 11 opens, it drives the winding column 15, which in turn drives the turntable 14 and the rotating column 12 to rotate around the axis, thereby compressing the coil spring 13 and gradually tightening it. When the protective curtain 11 is fully opened, it can protect the facilities below. When the protection ends, the motor 7 is reversed, and the protective curtain 11 slides back. Under the stress of the coil spring 13, it is finally rolled up again. The coil spring 13 ensures the reset and reusability of the entire protection device.
[0030] Reference Figure 1 , Figure 6 and Figure 7The opening and closing assembly includes multiple slide rails 18, one of which is opened and extends through the upper surface of the base plate 1, and another slide rail 18 is opened and extends through the lower surface of one of the long rods 3. A door frame 16 is slidably connected to the top of the base plate 1. Multiple vertical columns 2 are fixedly connected to the upper surface of the base plate 1. One of the vertical columns 2 and the outer wall of the door frame 16 are both fixedly connected to a mortise block 17. A fixing assembly is provided on the outer wall of the base plate 1. The outer walls of two mortise blocks 17 are slidably connected. A dovetail groove is opened on the inner wall of the mortise block 17. A tenon is slidably connected to the inner wall of the mortise block 17. The tenon is slidably connected in the dovetail groove. The upper and lower outer walls of the door frame 16 are slidably connected to the inner walls of the slide rails 18.
[0031] Specifically, the traditional dovetail tenon and mortise structure is used as the locking and unlocking structure of the movable door frame 16. A mortise block 17 is fixedly connected to both the vertical column 2 and the door frame 16. The two mortise blocks 17 can be assembled into a complete dovetail tenon and mortise structure. When the sliding door frame 16 assembles the two mortise blocks 17, the tenons can engage in the two dovetail grooves to form a lock, preventing geological disasters. The sliding rail 18 limits the movement of the door frame 16. The opening and closing components change the opening method of the protective device from the traditional swing type to the horizontal push-pull type. It can still be opened and closed freely in narrow spaces with insufficient width, which facilitates personnel to enter for installation and maintenance, and increases the applicability of the device.
[0032] Reference Figure 1 and Figure 8 The fixing component includes multiple fixing blocks 19, which are fixedly connected to the outer walls of both sides of the base plate 1. A rubber pad 20 is fixedly connected to the upper surface of the fixing block 19, and an abutment rod 21 is threadedly connected to the inner wall of the fixing block 19. The outer wall of the abutment rod 21 is fitted with a rubber pad 20.
[0033] Specifically, fixing blocks 19 are installed at the four corners of the outer walls on both sides of the base plate 1, and abutment rods 21 are threaded onto the inner walls of the fixing blocks 19. The entire assembly is fixed to the ground by rotating the abutment rods 21, and rubber pads 20 are used to increase friction and provide a certain buffering effect against vibrations caused by geological disasters.
[0034] Reference Figure 1 The top of the base plate 1 is provided with multiple support rods 6, and multiple long rods 3 are fixedly connected to the opposite side of the two horizontal columns 4. The multiple support rods 6 are fixedly connected to the opposite side of the outer wall of the two long rods 3, the multiple support rods 6 are fixedly connected to the opposite side of the two vertical columns 2, and the multiple support rods 6 are fixedly connected to the outer wall of the door frame 16.
[0035] Specifically, the overall framework of the protective structure is composed of a base plate 1, four vertical columns 2, two long poles 3, two horizontal columns 4, and a door frame 16. Multiple support rods 6 are used to connect and fix them, forming protection for the internal components. A triangular structure is used to enhance the overall stability.
[0036] Reference Figure 3 and Figure 4 The lead screw 8 is rotatably connected to the inner wall of one of the long rods 3 on the opposite side. A limit rod is fixedly connected to the inner wall of one of the long rods 3 on the opposite side. A slider 9 is threadedly connected to the outer wall of the lead screw 8. A slider 9 is slidably connected to the outer wall of the limit rod.
[0037] Specifically, when the screw 8 is driven to rotate by the motor 7 through the threaded connection, it can drive the slider 9 to slide. The limit rod ensures the stability of the slider 9's sliding and prevents it from rotating with the screw 8, thereby ensuring the stability of the protective curtain 11's winding and opening.
[0038] Working principle: When using this device to protect geological disaster monitoring facilities, place the device at the monitoring position, place the monitoring facility on the base plate 1, move along the slide rail 18 to close the door frame 16, so that the door frame 16 and the two mortise blocks 17 on the vertical column 2 fit together, and use tenons to make the tenons of the two engage to achieve the effect of locking the door.
[0039] Then, rotate the multiple abutment rods 21 on both sides of the base plate 1 to abut against the ground, so that the entire device can be stabilized on the ground;
[0040] When it rains or a geological disaster occurs causing rockfalls, the motor 7 is started, which drives the lead screw 8 to rotate. The slider 9, which is threaded onto the lead screw 8, slides along the direction of the lead screw 8, causing the traction rod 10 and the protective curtain 11 to slide synchronously. This causes the protective curtain 11 to gradually open from the outer wall of the winding column 15 until it covers the entire monitoring device, thus protecting the device from damage by rain or falling rocks. When the operation ends, the motor 7 is reversed, and the protective curtain 11 retracts. Under the action of the coil spring 13, the protective curtain 11 is rolled back onto the winding column 15, waiting for the next protection.
[0041] 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.
