Abstract
Description
Technical Field
[0001] This utility model relates to the field of earthquake monitoring technology, specifically to a safety protection box for underground earthquake monitoring equipment in mines. Background Technology
[0002] Underground coal mine seismic monitoring technology refers to using the vibrations induced by the coal cutting machine as a passive seismic source. By deploying sensors on both sides of the coal face to receive real-time signals, and using real-time processing of seismic exploration data and dynamic imaging technology, the technology dynamically monitors static geological conditions such as coal seam faults, collapse columns, and thinning zones within the working face. It also monitors and provides early warning of dynamic disaster conditions such as fractured zones, stress concentration zones, and outburst hazard zones in the coal seam roof. This provides data support for intelligent unmanned safe mining in coal mines. Protective boxes are needed to protect the seismic monitoring equipment during its movement.
[0003] The existing safety enclosure protects the seismic monitoring equipment. Operators open the enclosure and place the equipment in its designated position, preventing falling debris from damaging the device. The equipment includes a seismometer and a recorder. The seismometer receives ground motion, converts it into an electrical signal, and the recorder amplifies and stores the signal. Based on the inertia of a suspended pendulum, the ground moves while the pendulum remains stationary during an earthquake, creating a ground motion curve that indicates the earthquake's intensity. Another principle involves using multiple receivers to collect sound waves from the earthquake's epicenter and calculate the distance, depth, and intensity. However, if the protective enclosure is impacted and moves downwards, it can easily crush the seismic monitoring equipment, causing damage and affecting its normal operation.
[0004] The aforementioned safety protection box, because the protective plate is prone to squeezing the earthquake monitoring equipment during downward movement, can affect the operator's normal monitoring and thus reduce the effectiveness of the device. Utility Model Content
[0005] This utility model proposes a safety protection box for underground seismic monitoring equipment, which solves the problem that seismic monitoring equipment is easily damaged by compression in the prior art.
[0006] The technical solution of this utility model is as follows: A safety protection box for underground mine seismic monitoring equipment, comprising a protection box, and further comprising:
[0007] The blocking door is hinged to the front of the protective box. The connecting frame is installed inside the blocking door. A fixed column is slidably connected inside the connecting frame. A buffer spring is installed inside the connecting frame to facilitate pushing the fixed column outward. The outer end of the buffer spring is installed on the inner side of the fixed column. The connecting shaft is rotatably connected inside the fixed column. A fixing plate is installed on the outer end of the connecting shaft. A first connecting plate is installed on the outer side of the fixing plate. The device can flexibly move the auxiliary rod through the first and second connecting plates. An auxiliary frame is rotatably connected inside the first connecting plate. An auxiliary rod is slidably connected inside the auxiliary frame. A connecting pin passes through the outer side of the auxiliary frame. One end of the connecting pin, which passes through the auxiliary frame, abuts against the auxiliary rod. The second connecting plate is rotatably connected to the outside of the auxiliary rod. A support plate is installed on the lower surface of the second connecting plate.
[0008] As a preferred embodiment of the safety protection box for the underground earthquake monitoring equipment of this utility model, in order to better offset the impact force, a fixing tube is installed on the upper surface of the protection box, and an auxiliary spring is installed inside the fixing tube.
[0009] As a preferred embodiment of the safety protection box for the underground seismic monitoring equipment of this utility model, in order to reduce the impact on the auxiliary plate, a movable rod is installed at the top of the auxiliary spring, and the outer surface of the movable rod passes through the fixed tube.
[0010] As a preferred embodiment of the safety protection box for the underground seismic monitoring equipment of this utility model, in order to prevent the seismic monitoring equipment from being squeezed during the downward movement of the auxiliary plate, a support frame is installed on the upper surface of the protection box, and a padding layer is installed on the upper surface of the support frame.
[0011] As a preferred embodiment of the safety protection box for the underground seismic monitoring equipment of this utility model, in order to prevent falling objects from scattering everywhere, an auxiliary plate is installed at the top of the movable rod, and a protective frame is installed on the upper surface of the auxiliary plate.
[0012] As a preferred embodiment of the safety protection box for the underground seismic monitoring equipment of this utility model, in order to collect some of the fallen objects, an auxiliary groove is provided inside the protective frame, and the outer side of the protective frame is an inclined surface.
[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] In this invention, the buffer spring rebounds and drives the fixed column to move outward, causing the auxiliary rod 12 to unfold. Compared with the prior art of directly placing the earthquake monitoring equipment under the protective plate, this device can provide secondary protection for the earthquake monitoring equipment, preventing the auxiliary plate inside the device from moving downward and squeezing the earthquake monitoring equipment, thus improving the effectiveness of the device.
[0015] In this invention, the auxiliary plate moves downward and contacts the cushion layer, causing the cushion layer and support frame to block the auxiliary plate. Compared with the existing technology where the protective plate is placed above the earthquake monitoring equipment, this device blocks the downward-moving auxiliary plate, reduces the downward impact force of the auxiliary plate, and avoids damage to the earthquake monitoring equipment.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0023] like Figures 1-4As shown, this embodiment proposes a safety protection box for underground seismic monitoring equipment, including a protective box 1, and also includes a blocking door 4, a connecting frame 5, a fixing column 6, a buffer spring 7, a connecting shaft 8, a fixing plate 9, a first connecting plate 10, an auxiliary frame 11, an auxiliary rod 12, a connecting pin 13, a second connecting plate 14, and a support plate 15.
[0024] like Figure 4 As shown, the blocking door 4 is hinged to the front of the protective box 1. Operating the moving handle 26 flips the blocking door 4 upwards, causing the buffer spring 7 to eject the fixing post 6 outwards. The auxiliary frame 11 flips downwards due to gravity, causing the first connecting piece 10 to drive the fixing piece 9 downwards. The fixing piece 9 rotates along the inside of the fixing post 6 via the connecting shaft 8. It should be noted that when the blocking door 4 is closed, the auxiliary frame 11 is retracted to the back of the blocking door 4. The buffer spring 7 is compressed and stores kinetic energy; therefore, the reaction force of the buffer spring 7 can hold the support plate 15 in place, preventing the support plate 15 and auxiliary frame 11 from flipping. The connecting frame 5 is installed inside the blocking door 4, and the fixing post 6 is slidably connected inside the connecting frame 5. The buffer spring 7 is installed inside the connecting frame 5, and its outer end is installed on the inner side of the fixing post 6. The connecting shaft 8 is rotatably connected to the fixed column 6. A fixed plate 9 is installed on the outer end of the connecting shaft 8. A first connecting plate 10 is installed on the outer side of the fixed plate 9. An auxiliary frame 11 is rotatably connected inside the first connecting plate 10. An auxiliary rod 12 is slidably connected inside the auxiliary frame 11. A connecting pin 13 passes through the outer side of the auxiliary frame 11. One end of the connecting pin 13, which passes through the auxiliary frame 11, presses against the auxiliary rod 12. When the connecting pin 13 is pulled out, the auxiliary rod 12 is manipulated to move downward along the auxiliary frame 11. The downward movement of the auxiliary rod 12 causes the second connecting plate 14 to move downward. The downward movement of the second connecting plate 14 causes the support plate 15 to move downward, thus supporting the protective box 1. The auxiliary rod 12, the blocking door 4, and the protective box 1 form a stable structural combination. The second connecting plate 14 is rotatably connected to the outside of the auxiliary rod 12. A support plate 15 is installed on the lower surface of the second connecting plate 14.
[0025] like Figure 3As shown, a fixed tube 16 is installed on the upper surface of the protective box 1. An auxiliary spring 17 is installed inside the fixed tube 16. A moving rod 18 is installed at the top of the auxiliary spring 17. The moving rod 18 moves downward along the inside of the fixed tube 16, so that the moving rod 18 compresses the auxiliary spring 17 for buffering. The outer surface of the moving rod 18 passes through the fixed tube 16. A support frame 19 is installed on the upper surface of the protective box 1. An auxiliary plate 21 moves downward and contacts the pad 20, so that the support frame 19 supports the auxiliary plate 21, which can prevent the auxiliary plate 21 from hitting the protective box 1 due to excessive downward movement speed. A pad 20 is installed on the upper surface of the support frame 19. An auxiliary plate 21 is installed at the top of the moving rod 18. A protective frame 22 is installed on the upper surface of the auxiliary plate 21. An auxiliary groove 23 is opened inside the protective frame 22. The outer surface of the protective frame 22 is an inclined surface.
[0026] In this embodiment, as Figures 1-2 As shown, a movable column 2 is slidably connected inside the protective box 1. An installation plate 3 is installed on the upper surface of the movable column 2. An installation hole is opened on the upper surface of the installation plate 3. The earthquake monitoring equipment is placed on the upper surface of the installation plate 3 and then fixed to the upper surface of the installation plate 3 through the installation hole. A protective plate 24 is installed inside the protective box 1. An auxiliary frame 25 is installed on the upper surface of the protective plate 24. The upper surface of the auxiliary frame 25 is installed inside the protective box 1. A movable handle 26 is installed on the front of the blocking door 4.
[0027] In this embodiment, the movable column 2 is slid forward along the protective box 1 by manipulating the mounting plate 3, and the earthquake monitoring equipment is fixed on the mounting plate 3 through the mounting hole. The movable column 2 is then slid backward into the protective box 1, so that the mounting plate 3 can take the earthquake monitoring equipment into the protective box 1. The movable handle 26 is then manipulated to flip the blocking door 4 downward along the protective box 1 through the hinge and close it, so that the auxiliary frame 11 enters the protective box 1 and is pressed against the support plate 15 by the reaction force of the buffer spring 7.
[0028] Move the device to its designated location, and manipulate the moving handle 26 to flip the blocking door 4 upwards and open it. Simultaneously, the buffer spring 7 rebounds, causing the fixing post 6 to slide outwards along the connecting frame 5. The outward movement of the fixing post 6 causes the connecting shaft 8 to move outwards, which in turn causes the fixing plate 9 to move outwards. The outward movement of the fixing plate 9 causes the first connecting plate 10 to move outwards, which in turn causes the auxiliary frame 11 to move outwards. During this outward movement, the auxiliary frame 11 flips downwards due to gravity. As the auxiliary frame 11 flips downwards, it passes the first connecting plate 10, causing the fixing plate 9 to flip downwards as well. The fixing plate 9 then passes the connecting shaft 8... The auxiliary frame 11 flips downward along the inside of the fixed column 6, causing the auxiliary rod 12 to flip downward as well. Finally, the auxiliary frame 11 flips until it is perpendicular to the blocking door 4 and then stops. The connecting pin 13 is pulled out, and the auxiliary rod 12 is manipulated to move downward along the auxiliary frame 11. The downward movement of the auxiliary rod 12 causes the second connecting piece 14 to move downward, and the downward movement of the second connecting piece 14 causes the support plate 15 to move downward. The support plate 15 moves downward and contacts the ground. The connecting pin 13 is manipulated to pass through the auxiliary frame 11 and press against the auxiliary rod 12. The mounting plate 3 is manipulated to slide the moving column 2 forward along the protective box 1, moving the earthquake monitoring equipment to below the blocking door 4 for monitoring.
[0029] When the protective frame 22 is impacted, the falling object enters the auxiliary groove 23. The protective frame 22 moves downward, causing the auxiliary plate 21 to move downward. The auxiliary plate 21 moves downward, causing the moving rod 18 to move downward. The moving rod 18 moves downward along the inside of the fixed tube 16. The moving rod 18 moves downward and compresses the auxiliary spring 17, which buffers the impact force on the protective frame 22. The auxiliary plate 21 moves downward and contacts the pad 20, so that the support frame 19 blocks the auxiliary plate 21, preventing the auxiliary plate 21 from continuing to move downward and causing damage to the protective box 1.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
