Description

Technical Field

[0001] This application relates to the field of mine safety emergency facilities technology, specifically to a deep well safety house. Background Technology

[0002] Mining, especially deep mining, involves a complex working environment and faces multiple potential dangers such as gas explosions, water inrushes, and roof collapses. To ensure the safety of miners, emergency refuge facilities must be installed underground. The existing patent CN219587599U discloses a safety house device for emergency refuge in mines, which has certain defects. First, the structural stability is insufficient. Its stability mainly depends on the inclined steel cable and the bottom positioning ring. Under the complex geological conditions of deep wells, such as loose rock layers and impact pressure, this fixing method is not reliable enough and the installation efficiency is low. Second, the sealing performance of the sealing door is not described in detail, which poses a risk of leakage in disaster environments and makes it difficult to ensure the internal airtightness and safety. Therefore, a deep well safety house is proposed. Utility Model Content

[0003] The purpose of this application is to address the following technical problems: First, the structural stability is insufficient, as its stability mainly relies on the inclined steel cable and the bottom positioning ring. Under complex geological conditions in deep wells, such as loose rock layers and rock bursts, this fixing method is unreliable and has low installation efficiency. Second, the sealing performance of the sealing door is not described in detail, which poses a risk of leakage in disaster environments and makes it difficult to ensure internal airtightness and safety. This application provides a deep well safety house.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution: A deep well safety house includes a base, protective wall panels, and a protective top cover distributed from bottom to top. Multiple diagonal bracing mechanisms are provided on opposite sides of the base. An openable and closable sealing door is provided on the protective wall panel. An annular groove is constructed on the sealing door, and a sealing airbag capable of being inflated and deflated is provided in the annular groove. A lifting plate is slidably arranged on the base. Multiple moving wheels are provided on the lifting plate. A driving component is provided on the base to drive the lifting plate to slide.

[0005] Furthermore, the inclined support mechanism includes a fixed frame, a slider, a locking element, a support rod, and an inclined rod. The fixed frame is mounted on the base, the slider is slidably mounted on the fixed frame and locked by the locking element, the support rod is hinged to the fixed frame, and the two ends of the inclined rod are respectively hinged to the slider and the support rod.

[0006] Furthermore, the locking component includes a locking pin, a return spring, and two locking holes. The locking pin is slidably disposed on the slider, the return spring is disposed between the locking pin and the slider, and the two locking holes are both opened on the fixing frame and distributed vertically. The locking pin and the locking holes are inserted and engaged.

[0007] Furthermore, the outer surface of the protective wall panel is provided with multiple reinforcing ribs, which are distributed in a crisscrossing grid pattern.

[0008] Furthermore, the protective top cover includes an outer impact plate and an inner partition plate, with a buffer cavity formed between the outer impact plate and the inner partition plate, and the buffer cavity is filled with particulate energy-absorbing material.

[0009] Furthermore, the sealing door is equipped with an air pump, an air inlet pipe, and an air outlet pipe. The air inlet pipe is equipped with a one-way valve, and the air outlet pipe is equipped with an exhaust valve. Both the air inlet pipe and the air outlet pipe are connected to the sealing airbag, and the input end of the air pump is connected to the air inlet pipe.

[0010] Furthermore, multiple telescopic rods are provided between the lifting plate and the base.

[0011] Furthermore, the driving component includes a positive and negative lead screw, a drive motor, two drive blocks, and two drive rods. The positive and negative lead screw is rotatably mounted on the base. The output shaft of the drive motor is connected to the positive and negative lead screw. The two drive blocks are respectively threaded onto the positive and negative threaded sections of the positive and negative lead screw. The two drive rods are both hinged to the lifting plate, and their free ends are respectively hinged to the two drive blocks.

[0012] The beneficial effects of this application are as follows: 1. This application, by setting up a retractable and supportable inclined bracing mechanism, can quickly unfold during installation and form multi-directional support for the entire safety house, effectively enhancing the overall structural integrity and resistance to impact and compression. This design significantly improves the reliability under complex geological conditions in deep wells and overcomes the problems of insufficient stability and low installation efficiency caused by relying solely on inclined cables and bottom positioning rings in the existing technology.

[0013] 2. This application provides an annular groove with an inflatable and deflated sealing airbag on the sealed door. After the sealed door is closed, the airbag can be inflated to form a flexible sealing barrier between the door and the door frame. This structure can effectively adapt to minor deformations, ensure the airtightness of the enclosed space in a disaster environment, completely eliminate the hidden danger of harmful gas leakage, and provide a higher level of safety protection for people inside the danger zone.

[0014] 3. This application achieves a rapid transition between two states of easy movement and stable installation through the combined design of the lifting platform and the moving wheels. In the initial movement state, the base is off the ground and supported by the moving wheels, making it easy to transport to the designated location. During installation, the drive unit lifts the lifting platform so that the moving wheels are suspended in the air and the base is on the ground, which can quickly complete the positioning and installation. This integrated design greatly improves deployment efficiency and saves valuable emergency preparation time. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1-13As shown in the figure, an embodiment of this application proposes a deep well safety house, including a base 1, a protective wall panel 2, and a protective top cover 3 distributed from bottom to top. The base 1, the protective wall panel 2, and the protective top cover 3 are sequentially fixedly connected and enclose a sealed space. The base 1 and the protective wall panel 2 are both rectangular in shape, and the protective top cover 3 is arched. Multiple diagonal bracing mechanisms are provided on opposite sides of the base 1. The diagonal bracing mechanisms have two states: a retractable state to reduce the space occupied and a supporting state to provide overall support. The protective wall panel 2 is provided with an openable and closable... The sealing door 4 has an opening on the protective wall panel 2. The sealing door 4 is installed on the protective wall panel 2 by hinges and latches. The sealing door 4 can close or open the opening. The sealing door 4 has an annular groove 5. An air-sealing bladder 6 that can be inflated and deflated is installed in the annular groove 5. The air-sealing bladder 6 is fixed in the annular groove 5. A lifting plate 7 is slidably installed on the base 1. The lifting plate 7 slides in the vertical direction. Multiple moving wheels 8 are installed on the lifting plate 7. The multiple moving wheels 8 are evenly fixed at the bottom of the lifting plate 7. A driving component that can drive the lifting plate 7 to slide is installed on the base 1. In the initial state, all the diagonal bracing mechanisms are in a retracted state, the sealing door 4 is closed, the sealing airbag 6 is deflated, the lifting plate 7 is at its lowest position, all the moving wheels 8 are in contact with the ground, and there is a gap between the base 1 and the ground. At this point, the entire application is easy to move. During installation, the application is moved to a designated position, and the lifting plate 7 is driven upwards to its highest position by the drive mechanism. All the moving wheels 8 are then off the ground and suspended in the air, while the base 1 is in contact with the ground. Afterwards, the multiple diagonal bracing mechanisms are driven into a supporting state, providing support for the entire structure. In case of emergency evacuation, the sealed door 4 is opened, allowing the miner to enter the confined space. The sealed door 4 is then closed, and the sealed airbag 6 is inflated to create a seal between the sealed door 4 and the protective wall panel 2, ensuring the airtightness and safety of the confined space and eliminating the risk of leakage. When the emergency is over, the sealed airbag 6 is deflated, and the sealed door 4 is opened, allowing the miner to exit the confined space. In actual use, the confined space should be equipped with various emergency evacuation equipment and supplies, details of which will not be elaborated upon here.

[0019] like Figures 8-10 As shown, the specific structure of the diagonal bracing mechanism of this application is disclosed. The diagonal bracing mechanism includes a fixed frame 9, a slider 10, a locking member, a support rod 11, and a diagonal rod 12. The fixed frame 9 is mounted on the base 1 and is fixedly mounted on the base 1. The slider 10 is slidably mounted on the fixed frame 9 and locked by the locking member. The slider 10 slides in the vertical direction. The support rod 11 is hinged to the fixed frame 9. The two ends of the diagonal rod 12 are respectively hinged to the slider 10 and the support rod 11. Referring to the above, when the diagonal bracing mechanism is in the retracted state, the slider 10 is at its highest position, the support rod 11 is in the vertical direction, and the diagonal rod 12 is in the inclined direction. The slider 10 is locked by the locking device. In use, the slider 10 is first unlocked by the locking device, allowing the slider 10 to slide down to the lowest position. The diagonal rod 12 rotates to the inclined direction, and the support rod 11 rotates to the horizontal direction and contacts the ground. At this time, a stable triangular structure is formed between the fixing frame 9, the support rod 11, and the diagonal rod 12, which provides support. Then, the slider 10 is relocked by the locking device to ensure the stability of the support. The diagonal bracing mechanism is in the supported state.

[0020] like Figures 8-10 As shown, the specific structure of the locking component of this application is disclosed. The locking component includes a locking pin 13, a return spring 14, and two locking holes 15. The locking pin 13 is slidably disposed on the slider 10 and slides horizontally. The return spring 14 is disposed between the locking pin 13 and the slider 10. The return spring 14 is horizontal and its two ends are fixedly connected to the locking pin 13 and the slider 10 respectively. The two locking holes 15 are both opened on the fixing frame 9 and are distributed vertically. The locking holes 15 are horizontal and the locking pin 13 and the locking holes 15 are inserted into each other. Referring to the above, when the slider 10 is at its highest position, the return spring 14 is in its natural state, and the locking pin 13 engages with the upper locking hole 15. Due to the obstruction of the locking pin 13, the slider 10 cannot slide, thus locking the slider 10. Conversely, in use, when the locking pin 13 is pulled until it exits the upper locking hole 15, the return spring 14 is stretched. At this time, the slider 10 is no longer obstructed by the locking pin 13 and can slide down to the lowest position. After that, the locking pin 13 is released, the return spring 14 returns to its natural state, and the locking pin 13 engages with the lower locking hole 15, thereby relocking the locking pin 13.

[0021] like Figure 1 As shown, a further technical solution of this application is disclosed. The outer surface of the protective wall panel 2 is provided with a plurality of reinforcing ribs 16. The plurality of reinforcing ribs 16 are all fixed on the outer surface of the protective wall panel 2 and are distributed in a grid pattern with crisscrossing. Referring to the above, during use, the structural strength of the protective wall panel 2 can be enhanced and the overall stability improved by using multiple reinforcing ribs 16 distributed in a grid pattern.

[0022] like Figure 4 As shown, the specific structure of the protective top cover 3 of this application is disclosed. The protective top cover 3 includes an outer impact plate 301 and an inner partition plate 302. A buffer cavity is formed between the outer impact plate 301 and the inner partition plate 302. The buffer cavity is filled with particulate energy-absorbing material 303, which is rubber granules. Referring to the above, when the top of the protective cover 3 is impacted during use, the outer impact plate 301 first provides initial impact resistance, and then the energy is effectively absorbed and dispersed by the flow and deformation of the particulate energy-absorbing material 303, thereby improving the overall impact resistance and further enhancing the overall stability.

[0023] like Figures 12-13 As shown, the specific inflation and deflation method of the sealing airbag 6 of this application is disclosed. The sealing door 4 is provided with an air pump 17, an air inlet pipe 18 and an air outlet pipe 19. The air pump 17, the air inlet pipe 18 and the air outlet pipe 19 are all fixed inside the sealing door 4. A one-way valve 20 is provided on the air inlet pipe 18. The one-way valve 20 is fixed on the air inlet pipe 18 and plays a one-way conduction function. An exhaust valve 21 is provided on the air outlet pipe 19. The exhaust valve 21 is fixed on the air outlet pipe 19. The air inlet pipe 18 and the air outlet pipe 19 are both connected to the sealing airbag 6. The input end of the air pump 17 is connected to the air inlet pipe 18. Referring to the above, in the initial state, the exhaust valve 21 is closed. When in use, the air pump 17 is turned on to inflate the sealing airbag 6 through the air outlet pipe 19 until the sealing airbag 6 is inflated. The one-way valve 20 can ensure that the sealing airbag 6 will not leak when the air pump 17 stops working. Conversely, the exhaust valve 21 is turned on to release the air from the sealing airbag 6 until the sealing airbag 6 is deflated.

[0024] like Figure 7 As shown, a further technical solution of this application is disclosed. A plurality of telescopic sleeve rods 22 are provided between the lifting plate 7 and the base 1. The telescopic sleeve rods 22 are in a vertical direction. The telescopic sleeve rods 22 include an outer rod and an inner rod that are slidably engaged. The top end of the outer rod is fixedly connected to the base 1, and the bottom end of the inner rod is fixedly connected to the lifting plate 7. Referring to the above, when the lifting plate 7 slides, multiple telescopic sleeves 22 work together to guide, limit, and support, making the sliding of the lifting plate 7 more stable and further improving its stability in use.

[0025] like Figure 5 As shown, the specific structure of the driving component of this application is disclosed. The driving component includes a positive and negative lead screw 23, a drive motor 24, two drive blocks 25 and two drive rods 26. The positive and negative lead screw 23 is rotatably mounted on the base 1, and the axis of the positive and negative lead screw 23 is in the horizontal direction. The output shaft of the drive motor 24 is connected to the positive and negative lead screw 23. The drive motor 24 is fixed on the base 1. The two drive blocks 25 are respectively threaded on the positive and negative threaded sections of the positive and negative lead screw 23. The two drive rods 26 are both hinged on the lifting plate 7 and their free ends are respectively hinged to the two drive blocks 25. Referring to the above, when the lifting plate 7 is at its lowest position, the two drive blocks 25 approach each other, and the two drive rods 26 tend to be vertical. In use, the drive motor 24 is activated, the output shaft rotates forward, and the positive and negative lead screws 23 rotate together. The two drive blocks 25 move synchronously in opposite directions due to the action of the positive and negative threads until they move away from each other. The two drive rods 26 rotate synchronously in opposite directions around their respective hinge points until they tend to be horizontal. The lifting plate 7 slides upward to its highest position.

[0026] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
