Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] See appendix Figure 1 - Appendix Figure 7 A multi-functional interior attack search and rescue device includes a vehicle body 1, a fall arrestor 3, a cable winder 4, and a battery 5. The vehicle body 1 is equipped with a storage box 2 having a receiving cavity 20, and the storage box 2 is hinged with a box cover 21 for opening and closing the receiving cavity 20. The fall arrestor 3 is installed inside the receiving cavity 20, and the first end of the safety rope 31 of the fall arrestor 3 passes through the side wall of the receiving cavity 20, so that the connecting buckle 32 installed at the first end of the safety rope 31 is outside. The cable winder 4 is set on the vehicle body 1 and winds up the lighting cable 40. The battery 5 is installed inside the receiving cavity 20 and is electrically connected to the lighting cable 40.

[0042] Specifically, when in use, the lighting wire 40 has at least two usage methods:

[0043] In the first scenario, firefighters can pull out a lighting line 40 at the building's escape exit, then move vehicle 1 into the building. The lighting line 40, detached from the retractor 4, will be laid on the ground to form an indicator path and provide some illumination. Rescued personnel can move along the indicator path to the safe exit.

[0044] Alternatively, firefighters can first move vehicle 1 to the rescue location, then pull out the lighting line 40 to conduct search and rescue operations. Once the victim is found, they can be guided back to vehicle 1 along the directional path formed by the lighting line 40, and then escorted to a safe location by the firefighters remaining at vehicle 1.

[0045] During the rescue, firefighters can attach the connecting buckle 32 to their safety suits and then slowly move forward to search for trapped personnel. If a firefighter slips and loses their footing, the fall arrestor 3 will quickly tighten the safety rope 31, causing the firefighter wearing the safety suit to stop at the current position. After the rescue is completed, the firefighter can move closer to the vehicle body 1, which will cause the fall arrestor 3 to automatically wind up the safety rope 31.

[0046] If the lighting cable 40 is used in the first method, after the firefighter completes the rescue and returns to vehicle 1, he can move vehicle 1 along the indicated passage and simultaneously wind up the lighting cable 40 using the cable winder 4 until he returns to the building's safety exit, at which point he can remove the connecting buckle 32 from his safety suit. If the lighting cable 40 is used in the second method, after the firefighter completes the rescue and returns to vehicle 1, he needs to wind up the lighting cable 40 using the cable winder 4 before moving vehicle 1 to avoid the lighting cable 40 getting tangled in objects and affecting the movement of vehicle 1.

[0047] In summary, this multi-functional interior search and rescue device aims to solve many problems in the rescue process. By installing a winding device 4 on the vehicle body 1 for winding up the lighting cable 40, it is convenient to build a luminous indicator channel between the interior of the building and the safe location, so that firefighters or trapped personnel can identify and escape, and avoid missing the rescue opportunity. By installing a fall arrestor 3 on the vehicle body 1 for winding up and quickly tightening the safety rope 31, it prevents firefighters from falling during the rescue process and improves the safety of the search and rescue.

[0048] It should be noted that the fall arrestor 3, also known as a speed differential device, is a protective product that can quickly lock the fast-moving safety rope 31 within a limited distance, thereby quickly braking and locking the falling object. It is suitable for cargo hoisting, protecting the lives of ground operators and preventing damage to the hoisted workpiece. Since the fall arrestor 3 is existing technology, its specific structure and working principle will not be described in detail in this utility model.

[0049] See appendix Figure 1 - Appendix Figure 7 The receiving cavity 20 opens upward so that the lid 21 is hinged to the top of the storage box 2. The storage box 2 is also equipped with a locking element 210 for locking or unlocking the lid 21. The winding device 4 includes a support base 41 and a winding wheel 42. The support base 41 is detachably mounted on the top surface of the lid 21, and the winding wheel 42 is rotatably mounted on the support base 41 and used to wind up the lighting cord 40.

[0050] Specifically, when the cover 21 closes the receiving cavity 20, the support base 41 is installed on the cover 21, and the cover 21 is locked to the box body by the locking piece 210. Since the box body is fixed, the support base 41 can be restricted, so that the firefighter can stably wind up the lighting cable 40 by rotating the reel 42. When it is necessary to maintain the components inside the receiving cavity 20, the restriction between the support base 41 and the cover 21 is first released to remove the winder 4 from the cover 21, and then the restriction of the locking piece 210 on the cover 21 is released, that is, the cover 21 is flipped to open the receiving cavity 20 and expose the internal components.

[0051] Since the winding device 4 is installed on the top of the cover 21, the storage cavity and the winding device 4 are stacked on the vehicle body 1. This design not only facilitates the removal and placement of the winding device 4 and the access to the lighting wire 40, but also avoids the winding device 4 occupying the lateral space of the vehicle body 1, which can well regulate the overall installation space of the vehicle body 1.

[0052] It should be noted that the types of locks 210 used in the box structure are diverse, such as conventional mechanical locks, sealing locks, or directly using a latch structure. This utility model does not impose any restrictions on this.

[0053] See appendix Figure 1 - Appendix Figure 7 The top of the support base 41 of the winding device 4 is provided with a handle 412, and the bottom of the support base 41 is provided with two support rods 411. The top surface of the box cover 21 is provided with first buckles 211 on both sides. The two support rods 411 are connected to the two first buckles 211 in a one-to-one manner so that the support base 41 can be detachably installed on the top surface of the box cover 21.

[0054] Specifically, during installation, firefighters hold the handle 412 to lift the winder 4, so that the two rods 411 are aligned with the two first buckles 211 at the same time. Then, the winder 4 is lowered so that the two rods 411 are respectively engaged with the two first buckles 211. Under its own weight and the restraint of the first buckles 211, the winder 4 can be prevented from shaking up and down. Similarly, during disassembly, the winder 4 is lifted by holding the handle 412, so that the two rods 411 are disengaged from the two first buckles 211 at the same time. The winder 4 can then be removed from the cover 21, making it convenient for firefighters to flip the cover 21 and open the receiving cavity 20.

[0055] Furthermore, locking blocks 4110 can be installed at both ends of the support rod 411. When the support rod 411 is engaged with the first buckle 211, the two locking blocks 4110 are located on both sides of the first buckle 211. This design can limit the left and right swaying of the support rod 411 and further improve the installation stability of the winder 4.

[0056] It should be noted that, in addition to the above-mentioned installation structure, the support base 41 of the winding device 4 can also be installed on the cover 21 by screws, or the cover 21 can be detachably connected by other fixing methods. Since there are various related methods, this utility model does not limit them.

[0057] See appendix Figure 1 - Appendix Figure 7Regarding the driving method of the reel 42, there are at least two types: electric drive and manual drive. The electric drive type involves installing a motor (not shown in the figure) on the support base 41 and driving it coaxially with the reel 42. The motor controls the forward and reverse rotation of the reel 42 to achieve the winding and unwinding of the lighting cable 40. The manual drive type involves firefighters directly rotating the reel 42 manually. This utility model does not restrict which method is used to drive the reel 42, but considering the difficulty of power supply at the fire scene, the manual drive type is preferred. At the same time, in order to facilitate firefighters to operate the reel 42, a handle 420 can be installed on the side wall of the reel 42 for firefighters to hold.

[0058] See appendix Figure 1 - Appendix Figure 7 During the rescue operation, firefighters need to remain on-site to monitor vehicle 1. This serves several purposes: firstly, to stabilize vehicle 1 and prevent it from tipping over; secondly, to facilitate the winding of the lighting cable 40 and monitoring the battery level of the storage battery 5; and thirdly, to facilitate the rendezvous of rescued personnel. To provide air supply for the firefighters on-site and for the rescued personnel, this invention also includes an air supply unit 6. The air supply unit 6 is installed on vehicle 1 and includes a gas cylinder 61, a gas collecting valve 62, and an air supply terminal 63. The gas collecting valve 62 has an air inlet 621 and an air outlet 622. The air inlet 621 is connected to the gas cylinder 61 via a conduit, and the air outlet 622 is connected to the air supply terminal 63 via a conduit. The air supply terminal 63 can be connected to a breathing mask (not shown in the figure) for air supply.

[0059] Specifically, during use, the connector of the breathing mask is plugged into the air supply terminal 63, allowing the air in the gas cylinder 61 to be discharged into the breathing mask through the gas collecting valve 62 and the air supply terminal 63 for firefighters and rescued personnel to breathe; the whole process is plug-and-play and very convenient; therefore, the design of the air supply unit 6 enables this search and rescue device to supply air, providing firefighters and rescued personnel with a certain degree of safety, further increasing the functionality of the search and rescue device, and improving the overall user experience.

[0060] See appendix Figure 1 - Appendix Figure 7 Firefighters who are far from vehicle 1 and deep into building corridors for search and rescue operations need to wear portable external air cylinders for breathing. To reduce weight, external air cylinders are usually small in size and have a small air capacity, making it difficult to maintain use for a long time. In order to facilitate timely refilling of empty external air cylinders, the air supply unit 6 in this invention also includes an inflation end 64, and the air collection valve 62 is also provided with a quick-charge port 623. The quick-charge port 623 is connected to the inflation end 64 through a conduit. The inflation end 64 can be inserted into an external air cylinder (not shown in the figure). When the external air cylinder carried by the firefighter is low on air, he can return to the side of vehicle 1 and insert the inflation end 64 into the empty air cylinder for quick refilling, so that the firefighter can resume search and rescue work.

[0061] See appendix Figure 1 - Appendix Figure 7 After prolonged use, the gas supply inside the gas cylinder 61 may be exhausted. To facilitate timely replenishment of the gas supply, the gas supply unit 6 in this invention also includes a spare gas cylinder 65, which is installed on the vehicle body 1. When the gas supply inside the gas cylinder 61 is exhausted, the firefighters on duty can remove the corresponding spare gas cylinder 61 from the vehicle body 1 and replace it with the spare gas cylinder 65 to continue using it.

[0062] See appendix Figure 1 - Appendix Figure 7 The vehicle body 1 can be a conventional tracked vehicle, four-wheeled vehicle, etc., and this utility model does not limit it. For ease of understanding, in this embodiment, the vehicle body 1 includes a chassis 11, a fixing frame 12, and a push rod 13. The chassis 11 is equipped with universal wheels 111 and brake wheels 112 that are in contact with the ground at the front and rear ends, respectively. The fixing frame 12 is vertically installed in the middle of the chassis 11 and is divided into a front area and a rear area. The push rod 13 is installed on the fixing frame 12 and extends towards the rear area of ​​the vehicle body 1. The user can pull or push the vehicle body 1 by holding the push rod 13. The storage box 2 and the cable winder 4 are both located in the front area of ​​the vehicle body 1, and the storage box 2 is fixed to the fixing frame 12. The spare gas cylinder 65 is installed in the front area of ​​the vehicle body 1 and is located below the storage box 2. The gas storage cylinder 61 is installed in the rear area of ​​the vehicle body 1, and the gas collecting valve 62 and the gas supply end 63 are both installed on the top of the fixing frame 12.

[0063] Among them, the design of the omnidirectional wheel 111 makes the vehicle body 1 more flexible to move, and the design of the brake wheel 112 makes the vehicle body 1 able to be parked stably; while the fixed frame 12 divides the front and rear areas to install corresponding components, which firstly makes the functional areas independent, making it convenient for firefighters to quickly identify and use them, and secondly makes the overall layout of the vehicle body 1 more compact, improving portability.

[0064] See appendix Figure 1 - Appendix Figure 7 The gas cylinder 61 and the spare gas cylinder 65 can be fixed to the vehicle body 1 by means of snap-fit, bundling or other installation methods. Since there are many installation methods, this utility model does not limit them. For ease of understanding, in this embodiment, the front area of ​​the vehicle body 1 is provided with a strap 17 for bundling and fixing the spare gas cylinder 65, and the rear area of ​​the vehicle body 1 is provided with a fixing clip 18 for clamping and fixing the gas cylinder 61.

[0065] See appendix Figure 1 - Appendix Figure 7 The first end of the strap 17 is fixed to the vehicle body 1, and the second end of the strap 17 is provided with a buckle 170 for fixing to the vehicle body 1. The second end of the strap 17 can be knotted after passing through the buckle 170.

[0066] Specifically, during installation, the spare gas cylinder 65 is placed in the space enclosed by the strap 17 and the vehicle body 1. Then, the second end of the strap 17 is passed through the buckle 170 and tied. This will allow the strap 17 to secure the spare gas cylinder 65 to the vehicle body 1. During disassembly, the knot is untied and the strap 17 is loosened to remove or place the spare gas cylinder 65.

[0067] See appendix Figure 1 - Appendix Figure 7 The fixing clamp 18 includes a clamp seat 181, a clamp rod 182, and a plug 183. The clamp seat 181 is fixedly installed in the rear area of ​​the vehicle body 1. The first end of the clamp rod 182 is hinged to the clamp seat 181, and rotating the clamp rod 182 can enclose it with the clamp seat 181 to form a clamp opening 180 for placing the gas cylinder 61. The plug 183 is installed on the clamp seat 181 and can be inserted into or detached from the second end of the clamp rod 182 to fix or loosen the clamp opening 180.

[0068] Specifically, during installation, the gas cylinder 61 is inserted into the clamp 180, and then the second end of the clamp rod 182 is connected through the bolt 183 to lock the gas cylinder 61 onto the vehicle body 1; during disassembly, the bolt 183 is pulled out and the clamp rod 182 is rotated to open the clamp 180, so that the gas cylinder 61 can be taken out and put in.

[0069] See appendix Figure 1 - Appendix Figure 7 The present invention also includes a lighting unit 7, which includes a fog light 71, a warning light 72 and a control unit 73 installed on the vehicle body 1 or the storage box 2, and the control unit 73 is electrically connected to the battery 5, the fog light 71 and the warning light 72.

[0070] Specifically, firefighters can activate and deactivate the fog lights 71 and warning lights 72 via the control unit 73. The fog lights 71 provide illumination in a smoke-filled fire scene, while the warning lights 72 can provide guidance to those in distress, making it easier for them to approach the vehicle 1 on their own. Therefore, the design of the lighting unit 7 enables this search and rescue device to provide both illumination and guidance, further enhancing its functionality and improving the overall user experience.

[0071] See appendix Figure 1 - Appendix Figure 7 The control unit 73 includes a circuit board (not shown in the figure) and a control button 730. The circuit board is installed in the vehicle body 1 or the storage box 2, and the control button 730 is installed on the push rod 13. The circuit board is electrically connected to the control button 730, the battery 5, the fog light 71 and the warning light 72. Firefighters can send instructions to the circuit board by pressing the control button 730, and the circuit board will then start and stop the fog light 71 and the warning light 72.

[0072] See appendix Figure 1 - Appendix Figure 7The storage box 2 has a plug interface 22 that is electrically connected to the circuit board installed on the side wall or lid 21. The plug interface can be connected to the plug on the lighting line 40 (not shown in the figure), so that the battery 5 can supply power to the lighting line 40 normally. The plug interface can also be connected to an external power source, and it is convenient to charge the battery 5 when the power is low.

[0073] It should be noted that the plug interface, control component 73, etc. are all existing products. The technology of controlling the lamp through the control component 73 and the technology of powering and charging through the plug interface are all existing technologies. Therefore, the relevant structures and working principles will not be described in detail in this utility model.

[0074] Furthermore, wiring holes 23 can be designed on the side wall or cover 21 of the storage box 2 to facilitate wiring between the battery 5 and the control unit 73.

[0075] See appendix Figure 1 - Appendix Figure 7 The present invention also includes a leakage current detection rod 8, and a carrier box 14 and a second fastener 15 located directly above the carrier box 14 are also installed on the vehicle body 1. The bottom end of the leakage current detection rod 8 can extend into the carrier box 14 and abut against the inner wall of the carrier box 14, and the rod body of the leakage current detection rod 8 can be fastened to the second fastener 15.

[0076] Specifically, under normal circumstances, the leakage current detection rod 8 is supported by the carrier box 14 and snapped into the second fastener 15 to be stably fixed to the vehicle body 1. After firefighters arrive at the fire scene, they remove the leakage current detection rod 8 and then use it to detect the surrounding road conditions and whether there is any leakage on the ground to avoid potential risks. After the search and rescue is completed, the leakage current detection rod 8 can be installed back in its original position. Therefore, the design of the leakage current detection rod 8 enables this search and rescue device to have a pathfinding function, further increasing the functionality of the search and rescue device and improving the overall user experience.

[0077] See appendix Figure 1 - Appendix Figure 7 The present invention also includes a loudspeaker 9, and a storage tube 16 is installed on the vehicle body 1. The loudspeaker 9 can be detachably placed in the storage tube 16 for use.

[0078] Specifically, under normal circumstances, the megaphone 9 is placed inside the storage tube 16; during the search and rescue process, firefighters can take out the megaphone 9 to make announcements for the search and rescue; after the search and rescue is completed, the megaphone 9 can be placed back in its original position; therefore, the design of the megaphone 9 enables this search and rescue device to have amplification function, further increasing the functionality of the search and rescue device and improving the overall user experience.

[0079] It should also be noted that, although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application.
