Description
Technical Field
[0001] This utility model belongs to the field of life detection equipment, and in particular relates to a life detection device for coal mine rescue. Background Technology
[0002] Coal mines are a crucial part of the energy industry, and safe production is vital to miners' lives and social stability. In the event of an accident, rapid and effective rescue is paramount to minimize casualties and property damage. Among coal mine rescue tools, life detectors play a key role. Utilizing technologies such as audio-visual recording, radar, and infrared, they can accurately detect human vital signs. In the complex environment of a mine disaster, they help rescuers quickly and accurately locate trapped miners, providing crucial information for rescue operations, allowing rescue work to proceed efficiently, and ensuring the chances of survival for trapped miners.
[0003] In practical applications, most existing life detectors are attached to the operator's neck with a strap, allowing the device to hang naturally and rest against the operator's abdomen. While this design is convenient for carrying and operating the equipment under normal circumstances, allowing operators to focus more on the rescue work itself, as rescue operations progress, the situation on-site often becomes complex and changeable. Operators need to move frequently and bend over significantly. At this time, the life detector will droop due to its own weight and sway during the operator's movements. This swaying increases with the intensity and complexity of the movements. A swaying life detector is highly susceptible to collisions with external objects, leading to equipment damage and affecting its normal use. Furthermore, the swaying instrument may interfere with the operator's rescue actions, hindering other rescue efforts and ultimately negatively impacting the smooth progress of the rescue operation. Utility Model Content
[0004] The purpose of this utility model is to provide a life detection device for coal mine rescue, which can effectively prevent the life detector from shaking violently during the operator's physical activities, thus preventing collisions and affecting the operator's rescue actions.
[0005] The aforementioned life detection device for coal mine rescue includes a mounting plate with an "L"-shaped structure. A neck strap is connected to the horizontal section of the mounting plate, and a waist belt is connected to the vertical section of the mounting plate. Two guide rails are vertically fixed on the vertical section of the mounting plate. The life detector body is placed on the top of the horizontal section of the mounting plate and is located between the two guide rails. Two sliders that can slide along the corresponding guide rails are fixed on the life detector body. Locking components are provided on the guide rails for locking the inserted sliders. Several storage components for storing wires are provided on the waist belt.
[0006] Furthermore, the storage component includes a clip with an inverted "U" shape, which is snapped onto the belt, and a hook is fixed to the side wall of the clip facing away from the body.
[0007] Furthermore, the locking assembly includes a fixing screw, and the side wall of the guide rail has a threaded hole that communicates with the inside and outside. The fixing screw is inserted into the threaded hole and is threadedly engaged with it. The end of the fixing screw presses against the slider.
[0008] Furthermore, an extension plate is hinged to the end of the horizontal section of the mounting plate. When the extension plate swings to a horizontal position, the end face of its hinged end will fit against the end face of the hinged end of the mounting plate.
[0009] Furthermore, an abdominal pad is fixed to the side wall of the vertical section of the mounting plate that fits against the human abdomen.
[0010] Furthermore, the surface of the abdominal pad facing the human abdomen is arc-shaped.
[0011] Furthermore, a protective soft sheet is fixed on the vertical section of the mounting plate, and a fastener is provided on the unfixed end of the protective soft sheet for fixing it to the body of the life detector.
[0012] Compared with the prior art, the present invention has the following beneficial effects: Securely fasten the neck strap around the operator's neck, allowing the mounting plate to hang naturally. Next, fasten the waist belt around the operator's waist, tightening it appropriately to ensure the vertical section of the mounting plate fits snugly against the operator's abdomen. This effectively prevents significant swaying of the mounting plate, even during operator movement, thus preventing violent shaking of the life detector itself on the horizontal section of the mounting plate. The storage assembly neatly organizes and stores any loose wires connected to the life detector, such as probe wires, earphone wires, etc., preventing tangled wires and making them easier for the operator to access when needed. This life detection device for coal mine rescue effectively prevents violent swaying during operator movement, thus avoiding collisions with the life detector itself and preventing interference with the operator's rescue actions.

Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0015] Example This embodiment describes a life detection device for coal mine rescue, such as... Figure 1 , Figure 2 and Figure 6 Therefore, including the mounting plate 8, the mounting plate 8 has an "L" shaped structure; in this embodiment, the "L" shaped mounting plate 8 is mainly composed of a vertical section and a horizontal section. The horizontal section is used to place and support the life detector body 6, while the vertical section is used to fit the abdomen of the operator. An abdominal pad 2 is fixed to the side wall of the mounting plate 8 that fits against the human abdomen; such as Figure 2 , Figure 6 and Figure 8 As shown, the abdominal pad 2 is made of elastic and soft materials such as foam, silicone, and rubber. The abdominal pad 2 effectively improves the comfort of the operator when wearing it, while preventing pressure sores caused by prolonged wear. The side of the abdominal pad 2 facing the abdomen is arc-shaped, as shown... Figure 2 As shown, the arc-shaped structure can effectively increase the contact area with the operator's abdomen, avoiding excessive pressure concentration; A neck strap 4 is connected to the horizontal section of the mounting plate 8; such as Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the neck strap 4 is a strap with buckles. Straps with buckles are common products and are widely used in backpacks, suitcases, outdoor equipment, etc. The buckles have the ability to adjust the length of the strap. Therefore, the length of the neck strap 4 can be adjusted to suit the body shape of different operators. In use, the neck strap 4 is hung around the operator's neck, and the mounting plate 8 hangs down naturally. The vertical section of the mounting plate 8 fits against the operator's abdomen to facilitate carrying and operation. A belt 1 is connected to the vertical section of the mounting plate 8; such as Figure 1 , Figure 2 and Figure 5 As shown, the waist belt 1 is a strap with buckles. Straps with buckles are common products and are widely used in backpacks, suitcases, outdoor equipment, etc. The buckles have the function of adjusting the strap length. The vertical section of the mounting plate 8 fits tightly against the operator's abdomen to prevent the mounting plate 8 from swaying violently when the operator's body moves, thereby preventing the life detector body 6 on the horizontal section of the mounting plate 8 from swaying violently. Two guide rails 3 are vertically fixed on the vertical section of the mounting plate 8, and the life detector body 6 is placed on the top of the horizontal section of the mounting plate 8, with the life detector body 6 located between the two guide rails 3; Figure 2 , Figure 3 and Figure 6 As shown, the two guide rails 3 are located on the vertical section of the mounting plate 8 facing the side wall of the life detector body 6, and the two guide rails 3 are symmetrically distributed with a front-to-back interval; when the life detector body 6 is placed on the horizontal section of the mounting plate 8, the horizontal section of the mounting plate 8 can effectively support the life detector body 6, and the two guide rails 3 are located on the front and rear sides of the life detector body 6 respectively. The life detector body 6 has two sliders 11 fixed on it, which can slide along the corresponding guide rails 3 respectively; for example Figure 2 , Figure 3 and Figure 6 As shown, two sliders 11 are located on the front and rear side walls of the life detector body 6, respectively. There is a gap between the sliders 11 and the inner wall of the guide rail 3, allowing the sliders 11 to slide along the inside of the guide rail 3. In use, when the life detector body 6 needs to be placed on the mounting plate 8, the two sliders 11 can be aligned with the two guide rails 3 respectively, and the two sliders 11 can be inserted into the two guide rails 3 from top to bottom until the bottom of the life detector body 6 is in contact with the horizontal section of the mounting plate 8. The sliders 11 are positioned by the guide rails 3 to prevent the life detector body 6 from moving back and forth or left and right on the mounting plate 8, and to avoid the life detector body 6 slipping off the mounting plate 8 and being damaged. To elaborate further, such as Figure 3 and Figure 6As shown, in this embodiment, a preferred embodiment includes a fixing screw. A threaded hole with internal and external communication is provided on the side wall of the guide rail 3. The fixing screw passes through the threaded hole and is threadedly engaged with it. The end of the fixing screw presses against the slider 11. In use, after the life detector body 6 is placed on the mounting plate 8, tightening the fixing screw allows the end of the fixing screw to press tightly against the slider 11 inserted into the guide rail 3, thereby locking the slider 11 and preventing the life detector body 6 from moving upwards and coming out. This solution constitutes a locking assembly for locking the slider 11 after it is inserted into the guide rail 3. Alternatively, a positioning pin can be used as the locking assembly. A through hole is provided on the side wall of the guide rail 3, and a positioning hole is provided on the slider 11. When the slider 11 is inserted into the guide rail 3, the positioning hole aligns with the through hole. By inserting the positioning pin into the through hole and the positioning hole, the slider 11 can be effectively locked to prevent the life detector body 6 from moving upwards and coming out. The positioning pin and the positioning hole have an interference fit, preventing the positioning pin from easily coming out.
[0016] To elaborate further, such as Figure 1 , Figure 2 and Figure 6 As shown, this embodiment preferably includes a clip 10, which has an inverted "U" shape. The clip 10 is fastened to the waist belt 1, and a hook 9 is fixed to the side wall of the clip 10 facing away from the human body. In use, the clip 10 is fastened to the waist belt 1 from top to bottom, so that one end of the clip 10 is located between the waist belt 1 and the operator's abdomen. The friction generated by the tight fit can effectively prevent the clip 10 from falling off. Afterwards, the operator can hang the remaining sections of the probe wires, probe cables, earphone wires, etc., connected to the life detector body 6 on the hook 9 to organize and store these wires, preventing them from being scattered and making it more convenient for the operator to use them. This solution as a whole constitutes a storage component for storing wires. By setting several storage components on the waist belt 1, wires for different purposes can be stored separately, which can facilitate the operator to quickly identify and use them. Of course, the storage component can also use a cable reel. The cable reel is an existing product, also known as a cable reel, spool, or cable winder. It is a device used to wind, store, and release cables. It is electrically driven and uses magnetic coupling to achieve automatic cable winding and unwinding. It is widely used in power transmission, industrial equipment, household appliances, and outdoor operations. The cable reel is fixed to a sliding sleeve fitted on the belt 1. The position of the cable reel can be adjusted by moving the sliding sleeve. In use, the cable reel can be used to store the wires on the life detector body 6.
[0017] An extension plate 7 is hinged to the end of the horizontal section of the mounting plate 8. When the extension plate 7 swings to a horizontal position, the end face of its hinged end will fit against the end face of the hinged end of the mounting plate 8; for example Figure 1 and Figure 8As shown, in this embodiment, the horizontal section of the extension plate 7 and the mounting plate 8 are hinged together by a pivot. A pivot is horizontally fixed on the front and rear sidewalls of the horizontal section of the mounting plate 8, and a hinge sleeve is horizontally fixed on the front and rear sidewalls of the extension plate 7. The two hinge sleeves are distributed and fitted onto the two pivots, allowing the extension plate 7 to swing about the pivot. When the extension plate 7 swings upwards and is parallel to and attached to the top of the horizontal section of the mounting plate 8, as shown... Figure 1 As shown, the extension plate 7 can be effectively stored, reducing space occupation; when the extension plate 7 swings outward and unfolds, the extension plate 7 is horizontal, and the hinge end face of the extension plate 7 will fit against the hinge end face of the mounting plate 8, as shown. Figure 8 As shown, the extension plate 7, which has been swinging to a horizontal position, is limited to keep it horizontal. The extended plate 7, once unfolded, can be used to place unused or ready-to-use instruments as a temporary storage point. A protective film 5 is fixed to the vertical section of the mounting plate 8; such as Figure 1 As shown, the protective film 5 is fixed to the top of the vertical section of the mounting plate 8. The protective film 5 is made of materials such as rubber, leather, and silicone, which can be bent and deformed; for example... Figure 1 and Figure 5 As shown, the protective film 5 can be bent to cover the top of the life detector body 6, protecting the screen, switch, and buttons on the top of the life detector body 6 from accidental touches, bumps, water splashes, and other emergencies when not in use; the unfixed end of the protective film 5 is provided with a fastener for fixing it to the life detector body 6; as shown Figure 6 As shown, in this embodiment, the fastener uses double-sided adhesive. The double-sided adhesive is pasted onto the unfixed end of the protective film 5. When the protective film 5 is bent to cover the top of the life detector body 6, the unfixed end of the protective film 5 can be pasted onto the life detector body 6 through the double-sided adhesive to prevent the protective film 5 from loosening. Of course, the fastener can also be a magnet. The magnet is fixed to the unfixed end of the protective film 5, and an iron plate is fixed on the life detector body 6. Through the attraction between the magnet and the iron plate, the unfixed end of the protective film 5 is attracted to the life detector body 6.
[0018] In actual use, the neck strap 4 is securely hung around the operator's neck, allowing the mounting plate 8 to hang down naturally; then, the waist belt 1 is tied around the operator's waist, and by tightening the waist belt 1 appropriately, the vertical section of the mounting plate 8 is tightly fitted against the operator's abdomen; in this way, even if the operator moves his body, the mounting plate 8 can be effectively prevented from swaying or shaking significantly. When installing the life detector body 6, first align the two sliders 11 with the tops of the two guide rails 3 respectively. Then, insert the two sliders 11 into the two guide rails 3 one by one from top to bottom until the bottom of the life detector body 6 is completely in contact with the horizontal section of the mounting plate 8. At this time, tighten the fixing screws to firmly lock the sliders 11, thereby preventing the life detector body 6 from slipping off the mounting plate 8 and being damaged. Next, clip 10 is fastened onto belt 1 from top to bottom, with one end of clip 10 positioned between belt 1 and operator's abdomen. The friction generated by this tight fit effectively prevents clip 10 from accidentally coming off. Subsequently, the operator can hang the remaining parts of the probe wires, probe cables, earphone wires, etc., connected to the life detector body 6 on hook 9 to organize and store these wires, preventing them from becoming tangled and making it more convenient for the operator to access them when needed. This life detection device for coal mine rescue can effectively prevent violent swaying and shaking during the operator's physical activities, thereby preventing the life detector body 6 from being bumped or affecting the operator's rescue actions.
