Description

Technical Field

[0001] This invention relates to the field of search and rescue dog equipment technology, and in particular to a multifunctional auxiliary protection device for search and rescue dogs. Background Technology

[0002] In the event of disasters such as earthquakes and fires, timely search and rescue of survivors is essential. However, in the face of building collapses caused by earthquakes, it is extremely challenging for rescuers to directly enter the complex and intricate interiors of collapsed buildings. Because humans are relatively large compared to search dogs, they struggle to maneuver nimbly through small spaces or passageways, significantly increasing the difficulty of the search. Using search dogs, however, reduces the difficulty due to their agility, and their keen sense of smell greatly increases the chances of finding survivors. Furthermore, in fire environments, using search dogs to rescue survivors is advantageous because their walking posture, where both legs touch the ground simultaneously, effectively avoids the risk of rescuers directly entering the fire and inhaling dense smoke from higher levels of the search area.

[0003] However, when search and rescue dogs enter collapsed buildings or fire scenes, they face complex environments such as exposed rebar, broken glass, and sharp pieces of wood. During actual search and rescue operations, they may traverse narrow paths. If these hazards exist along the path, they can cause injury to the dog's body. Furthermore, since the dog's abdomen is directly facing downwards, injuries from sharp objects to the abdomen are often severe and can even threaten its life. Current search and rescue dog auxiliary equipment typically consists of protective clothing directly covering the dog's body. While this provides surface protection, the clothing can easily shift during running, leaving the abdomen unprotected. Additionally, there are no alarms or additional safeguards in place if the protective clothing's internal structure is damaged or if sharp objects breach its structure, posing a serious threat to the dog's life and health.

[0004] In addition, search and rescue dogs may face high or low temperature environments during actual search and rescue operations. In high-temperature environments, the dog's paws directly contact the hot ground and are baked by the heat. In low-temperature environments, the dog's paws directly contact the ground and are easily frozen, thus affecting the dog's sensitivity during actual search and rescue operations. Summary of the Invention

[0005] The main purpose of this invention is to propose a multifunctional auxiliary protection device for search and rescue dogs, which aims to effectively solve the technical problems encountered in search and rescue work, so that the abdomen of the search and rescue dog is well protected. Depending on the application scenario, it can appropriately dissipate heat or keep warm, and can promptly detect damage to the protective clothing and provide further protection with inflatable air bags. In conjunction with the application of foot covers, the feet of the search and rescue dog are further protected.

[0006] To achieve the above objectives, the present invention proposes a multifunctional search and rescue dog auxiliary protection device, including a protective suit body, a protective suit support on the bottom surface of the protective suit body, and when the protective suit body and the search and rescue dog torso are connected, the protective suit support supports the protective suit body and the shape of the search and rescue dog torso are mutually matched. As the body posture of the search and rescue dog changes, the various structures of the protective suit support swing and change shape relative to each other.

[0007] Preferably, the protective clothing support frame has a first transition material at least at the middle position along the first direction, and a second transition material at the middle position in the second direction, wherein the first transition material and the second transition material are intersecting.

[0008] Preferably, the protective suit body comprises, from the inside out, an inner surface layer, a middle layer, and an outer surface layer, wherein the middle layer can move linearly relative to the inner surface and / or the outer surface layer; the inner surface layer and the outer surface layer are respectively provided with ventilation holes, and the middle layer is provided with a ventilation area and a sealing area; when the structure of the ventilation area is opposite to the ventilation holes, the protective suit body is in a ventilation state; when the sealing area is completely opposite to the ventilation holes, the protective suit body is in a heat preservation state.

[0009] Preferably, the outer surface of the outer layer is provided with a plurality of fasteners, the fasteners are provided with channels, the fasteners are provided with openings, and the channels inside the fasteners are provided with a plurality of positioning holes at different positions; the middle layer is connected to a movable part that cooperates with the fasteners, the main body of the movable part is a strip structure, the main body of the movable part is matched with the channel inside the fasteners, and the two ends of the main body of the movable part are provided with positioning blocks, and the positioning blocks and positioning holes are connected and positioned by insertion.

[0010] Preferably, the inner surface is provided with a plurality of inflatable air bags. When the inflatable air bags are in the non-inflated state, they are located in the space between the protective suit body and the search and rescue dog's torso, supporting different positions of the search and rescue dog's torso. When the inflatable air bags are in the inflated state, they push the protective suit body away from the search and rescue dog's torso and form a channel for air to circulate along the front-back direction of the protective suit body. The inflatable air bags on the left and right sides and the protective suit frame together form a triangular support system for supporting the search and rescue dog's torso.

[0011] Preferably, the protective suit body is provided with a detection circuit for detecting damage to the protective suit body, and the detection circuit is arranged in a roundabout manner; when the protective suit body is damaged and the detection circuit is broken, the inflatable air bag enters the inflation state; the inflatable air bag is connected to a sensor for detecting air pressure.

[0012] Preferably, the protective suit body has a marker release device at the front, the marker release device has a cavity inside, and several marker placement shells are provided at the bottom of the cavity. The bottom of the marker placement shell is connected to the mounting shell and has a release hole. The top of the marker placement shell has a top hole. The top holes of the several marker placement shells are aligned in a straight line. The mounting shell also has a battery and a servo motor. The battery provides power to the servo motor. The rotating shaft of the servo motor is connected to a rotating wheel. One end of a steel wire rope is connected to the surface of the rotating wheel. The other end of the steel wire rope passes through the top holes of all the marker placement shells. When the marker is installed inside the marker placement shell and reaches the top limit position, the hanging hole at the top of the marker and the top hole of the marker placement shell are aligned in the same axis. The other end of the steel wire rope also passes through the top hole of the marker placement shell and the hanging hole at the top of the marker.

[0013] Preferably, the marker is cylindrical in shape, with a groove at the top connected to a spring, and a hanging hole at the top of the marker in the middle. The other end of the steel wire rope can pass through both the top hole of the marker placement housing and the hanging hole in the middle of the marker simultaneously to confine the marker inside the marker placement housing. When the top of the marker moves upward and contacts the inner top surface of the marker placement housing, the central axis of the hanging hole in the middle of the marker and the central axis of the top hole of the marker placement housing are on the same horizontal plane. A foolproof structure is provided through the mutual cooperation between the marker and the marker placement housing. The outer circumference of the marker has a protruding rib along the axial direction, and the inner wall of the marker placement housing has an inner groove along the axial direction. As the marker gradually moves upward along the marker placement housing, the protruding rib and the inner groove cooperate to move axially, which can prevent the marker from rotating radially relative to the marker placement housing.

[0014] Preferably, the multifunctional search and rescue dog auxiliary protection device further includes a foot cover that fits over the paw of the search and rescue dog. The foot cover includes an upper foot cover body and a foot cover sole. A side ventilation opening is provided at the upper front part of the foot cover body, and a toe through hole is provided at the lower front part of the foot cover body. Several metal support blocks are provided on the bottom surface of the foot cover sole, and each metal support block corresponds to the paw position of the search and rescue dog. Several ventilation channels with internal grooves are provided on the inner side of the foot cover body. The ventilation channels extend from the front of the foot cover body to the rear. A through hole is provided on the back of the foot cover body, and the through hole passes directly through the foot cover body.

[0015] Preferably, when the search and rescue dog is conducting search and rescue in a cold environment, an inner sleeve is put on the dog's foot. The outer surface of the inner sleeve is provided with a meandering sealed air tube. The sealed air tube can be set from top to bottom and is set as a multi-layer structure. Each layer is a vertical ventilation method. When the inner sleeve is put on the surface of the search and rescue dog's foot, the foot and the inner sleeve enter the body of the foot sleeve at the same time. The sealed air tube is tightly fitted with the ventilation duct to close the ventilation duct.

[0016] The technical solution of this invention has the following advantages over the prior art:

[0017] The protective suit body of the multifunctional search and rescue dog auxiliary protection device of the present invention can cover the abdomen of the search and rescue dog. The protective suit body is connected to the protective suit frame, which can support the protective suit body. The protective suit body fits better with the surface of the search and rescue dog's torso. Furthermore, the protective suit frame is equipped with an elastic transition material inside, which allows the protective suit frame to better adapt to the actual search and rescue posture changes of the search and rescue dog.

[0018] The technical solution of this invention features breathable holes on the inner and outer surfaces that can interact with the ventilation or sealing areas of the middle layer to achieve switching between breathability and heat preservation. Furthermore, this invention incorporates inflatable air bags on the surface of the protective suit that fits the search and rescue dog's torso, allowing for a closer fit. When inflated, these air bags work in conjunction with the suit's frame to form a support and protection system. Finally, this invention includes a marker release device; the built-in markers are released promptly in response to signals emitted by the search and rescue dog, allowing for timely marking of any survivors found.

[0019] Furthermore, the foot cover of the present invention can separate the search and rescue dog's feet from the ground, providing heat insulation and protection. In addition, the inner cover used inside the foot cover can keep the search and rescue dog warm in low-temperature environments. Attached Figure Description

[0044] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] This invention proposes a multifunctional search and rescue dog auxiliary protection device.

[0047] Example 1

[0048] Please see Figure 1-4 The multifunctional search and rescue dog auxiliary protection device in this embodiment of the invention includes a protective suit body 1, and a protective suit support 2 is provided on the bottom surface of the protective suit body 1. When the protective suit body 1 is connected to the torso of the search and rescue dog, the protective suit support 1 and the surface shape of the search and rescue dog torso cooperate and are positioned with each other.

[0049] Specifically, the protective suit support 2 in this embodiment of the invention has a plate-like structure. The top surface 21 of the protective suit support 2 is connected to the bottom surface of the protective suit body 1, and can be connected by means of adhesive bonding or other methods. Since the search and rescue dog is located on its abdomen, its surface from front to back has an overall convex shape. The top surface 21 of the protective suit support 2 in this embodiment of the invention is a concave curved surface 22. When the protective suit body 1 is connected to the abdominal surface of the search and rescue dog, the protective suit support 2, located on the outer surface of the protective suit body 1, has two ends that bulge upwards and a middle that is concave downwards. Therefore, the protective suit support 2 can support the protective suit body 1 upwards, and the protective suit body 1 fits the search and rescue dog's body more closely. Furthermore, when the protective suit body and the search and rescue dog are closely connected, the positional relationship from top to bottom is: search and rescue dog body, protective suit body 1, and protective suit support 2.

[0050] Please see Figure 3 and 4 Preferably, the protective suit support 2 in this embodiment of the invention is a plate structure. When the protective suit body 1 is worn on the surface of the search and rescue dog's body, the protective suit support 2 supports the protective suit body 1 upwards to fit the search and rescue dog's body surface, resulting in a higher degree of fit between the protective suit body 1 and the search and rescue dog's torso. The protective suit support 2 can be made of carbon fiber material to achieve overall lightweighting and good wear resistance.

[0051] Please see Figure 2 and 3 Since search and rescue dogs may have their legs bent or their bodies compressed downwards during actual search and rescue operations, the main body of the protective clothing support 2 in this embodiment of the invention is made of deformable material and has a split structure.

[0052] Specifically, since the protective suit support 2 of this embodiment is generally elongated, a first transition material 23 is provided at the middle position along the first direction, and a second transition material 24 is provided at the middle position along the second direction. The protective suit support 2 is divided into several structural blocks by the first transition material 23 and the second transition material 24. The structural blocks are not directly connected, but are indirectly connected by the first transition material 23 or the second transition material 24. For example, in this embodiment, the protective suit support 2 is divided into four structural blocks by the first transition material 23 and the second transition material 24.

[0053] Meanwhile, the first transition material 23 and the second transition material 24 are made of elastic materials, and the elasticity of the first transition material 23 and the second transition material 24 is greater than that of the structural block. The entire protective suit frame 2 is produced by two-color injection molding. That is, in this embodiment of the invention, the first transition material 23 and the second transition material 24 divide the protective suit frame 2 into four structural blocks, and the four structural blocks are indirectly connected by the first transition material 23 and the second transition material 24. The first transition material 23 and the second transition material 24 can elastically deform, and the four structural blocks can swing relative to each other at a relative angle and move relative to each other. During the actual operation of the search and rescue dog, the overall shape of the protective suit frame 2 changes from its original concave shape to a flat structure, or other changes. During the actual rescue, the search and rescue dog compresses its posture downwards, and the four structural blocks can swing relative to each other, changing into a near-planar connection shape. This can protect the abdomen of the search and rescue dog and also make it easy to pass through different shaped channels during the actual search and rescue process, which is more in line with the actual search and rescue work requirements. In addition, in other embodiments of the present invention, besides the appendix of the present invention Figure 2 , 3 The first transition material 23 and the second transition material 24 intersect in a cross shape. More transition materials can be added to form a cross-shaped intermediate connection structure system, thereby dispersing the protective clothing support 2 into more structural blocks.

[0054] Please see Figure 1 The protective suit body 1 is provided with a side positioning groove 101 that is adapted to the legs of the search and rescue dog. The side positioning groove 101 has an outward opening. When the protective suit body 1 is connected to the torso of the search and rescue dog, by inserting the legs of the search and rescue dog into the side positioning groove 101 along the opening of the positioning groove 101, and then pulling or shifting the protective suit body 1 towards the head or tail of the search and rescue dog, the connection between the protective suit body 1 and the search and rescue dog can be made more accurate and tighter.

[0055] Example 2

[0056] Please see Figure 5-6In this embodiment of the invention, a positioning ring 102 can be connected to the side of the side positioning groove 101. The positioning ring 102 has a central through hole 103. When the search and rescue dog wears the protective suit body 1, its limbs are inserted into the central through hole 103 of the positioning ring 102. A connecting strap (not shown in the figure) is then provided along the edge of the protective suit body 1, with a buckle at the end of the strap. This allows for quick and easy donning of the protective suit body 1 and the search and rescue dog, and the connecting strap and buckle securely connect the protective suit body 1 and the search and rescue dog's body, preventing displacement after donning. The positioning ring 102 can be made of an elastic material, resulting in a higher degree of connection between the positioning ring 102 and the search and rescue dog's legs. Preferably, the positioning ring 102 is connected to the bottom surface of the protective suit body 1.

[0057] Example 3

[0058] Search and rescue dogs often face high-temperature or low-temperature environments during actual search and rescue operations. When searching and rescue dogs are in high-temperature environments, they need good heat dissipation conditions, while in low-temperature environments, they need good heat preservation conditions.

[0059] Please see Figure 7 , 8 The protective suit body 1 of this invention has a three-layer structure, mainly including an inner surface layer 104, a middle layer 105, and an outer surface layer 106 from the inside out. The middle layer 105 is disposed between the inner surface layer 104 and the outer surface layer 106. The middle layer 105 can move or be fixed relative to the inner surface layer 104 and the outer surface layer 106 in the space between them. The inner surface layer 104, the middle layer 105, and the outer surface layer 106 together constitute the main structure of the protective suit body 1.

[0060] In addition, the inner surface layer 104 and the outer surface layer 106 are respectively provided with ventilation holes 107. The ventilation holes 107 on the surface of the inner surface layer 104 and the ventilation holes 107 on the surface of the outer surface layer 106 are arranged opposite to each other. When the middle layer 105 does not block the ventilation holes 107 of the inner surface layer 104 and the outer surface layer 106, the outside air can enter the body surface of the search and rescue dog through the ventilation holes 107, and the heat collected from the body surface of the search and rescue dog can flow out through the ventilation holes 107 to ensure air circulation.

[0061] Please see Figure 9 In addition, the surface of the intermediate layer 105 is provided with a ventilation area 1051 and a sealing area 1052. When the intermediate layer 105 moves relative to the inner surface layer 104 and the outer surface layer 106, the relative positions of the ventilation area 1051 and the sealing area 1052 and the vent 107 change.

[0062] When search and rescue dogs are conducting search and rescue operations in high-temperature environments, the ventilation area 1051 on the surface of the middle layer 105 is aligned with the ventilation holes 107 on the surfaces of the inner and outer layers 104 and 106, allowing hot air or heat between the search and rescue dog and the main body of the protective suit 1 to be released outward through the ventilation area 1051 and the ventilation holes 107. If the search and rescue dog needs to conduct search and rescue operations in cold environments, the ventilation holes 107 can be blocked by aligning the sealing area 1052 with the ventilation holes 107, preventing excessive heat loss from the search and rescue dog's body surface and achieving a heat preservation effect.

[0063] Preferably, the ventilation area 1051 on the surface of the intermediate layer 105 can be set as a metal wire mesh layer. This not only achieves heat dissipation, but also prevents sharp objects from scratching the abdomen of the search and rescue dog during the actual search and rescue process.

[0064] Please see Figure 9-12 Preferably, since the intermediate layer 105 is disposed between the inner surface layer 104 and the outer surface layer 106, and the ventilation area 1051 and sealing area 1052 disposed on the surface of the intermediate layer 105 need to be moved to achieve the switching between heat preservation and ventilation functions, a number of fixing members 3 are disposed on the outer surface layer 106, and a number of movable members 4 are connected to the intermediate layer 105. The movable members 4 can move and be fixed relative to the fixing members 3. When the connection position is determined, the movable members 4 and the fixing members 3 are fixedly connected to achieve the fixed connection position between the intermediate layer 105 and the outer surface layer 106.

[0065] Specifically, in this embodiment of the invention, the fixing member 3 is disposed on the surface of the outer layer 106, the fixing member 3 has an internal channel 31, and the surface of the fixing member 3 has an opening 32. A plurality of positioning holes 33 are provided at different positions within the internal channel 31 of the fixing member 3. In this embodiment of the invention, the main body 41 of the movable member 4 is a strip-shaped structure, and the main body 41 of the movable member 4 matches the internal channel 31 of the fixing member 3, meaning that the main body of the movable member 4 can move back and forth along the internal channel 31 of the fixing member 3. Two positioning blocks 42 are provided at both ends of the main body 41 of the movable member 4, wherein the positioning blocks 42 are engaged and connected with the positioning holes 33 for positioning.

[0066] Furthermore, the width of the positioning hole 33 of the fixing member 3 is greater than the width of the channel 31, while the width of the positioning block 42 of the movable member 4 is greater than the width of the main body 41 of the movable member 4. Therefore, the positioning block 42 of the movable member 4 is connected to the positioning holes 33 at different positions, thereby realizing the connection relationship between the movable member 4 and the fixing member 3 at different positions. In addition, the main body of the movable member 4 is provided with an outwardly protruding protrusion 43, part of the structure of the protrusion 43 extends outward through the channel 31, and the bottom of the main body 41 of the movable member 4 is provided with a bottom connecting block 44, which passes through the bottom through hole of the channel 31 and is connected to the intermediate layer 105. Preferably, the bottom connecting block 44 is made of elastic material, so the bottom connecting block 44 can be elastically pulled outward, thereby allowing the intermediate layer 105 to move relative to the inner surface layer 104 and the outer surface layer 106, and to be reset when not elastically pulled out, so that the movable member 4 and the fixing member 3 can be inserted and connected.

[0067] Therefore, in order to adjust the different connection positions of the intermediate layer 105 with the inner surface layer 104 and the outer surface layer 106, the protruding block 43 is pulled out of the channel 31 and moved relative to the channel 31. Finally, a suitable positioning hole 33 is selected, and the positioning block 42 is pressed into the positioning hole 33 in the new position. This makes it easy to adjust the different connection positions of the positioning block 42 and the positioning hole 33, adjust the different connection positions of the intermediate layer 105 with the inner surface layer 104 and the outer surface layer 106, and adjust the different mating positions or relationships between the ventilation area 1051 or the sealing area 1052 and the vent hole 107.

[0068] In actual search and rescue operations, when facing high-temperature environments, it is necessary to ensure good breathability between the protective clothing and the dog's body. In low-temperature environments, it is necessary to ensure good thermal insulation.

[0069] Please see Figure 7 In this invention, the protective suit used for search and rescue dogs includes a main body 1 and a protective suit harness connector (not shown in the figure). The main body 1 of the protective suit is mainly fitted to the abdomen of the search and rescue dog to protect the abdomen. The protective suit harness connector can extend upwards in a locking manner and connect to the back of the search and rescue dog, so that the protective suit and the torso of the search and rescue dog can be reliably connected.

[0070] Preferably, elastic transition fabric areas are provided along both sides of the protective suit body, and these areas connect the protective suit straps to the protective suit body 1. The force transmission path from the protective suit straps to the protective suit body inevitably passes through the elastic transition fabric areas, which are capable of elastic stretching and contraction. When the protective suit is connected to the search and rescue dog's torso, it can be longitudinally stretched or shortened through the elastic transition fabric areas. The protective suit body 1 can be used with search and rescue dogs of different sizes, and the protective suit body 1 is reliably and tightly connected to the search and rescue dog's torso.

[0071] Meanwhile, the inner surface 104 of the protective suit body 1 is provided with several inflatable air bags 5. The inflatable air bags 5 are made of soft material. When the inflatable air bags 5 are not inflated, they are attached to the surface of the protective suit body 1. Together with the elastic transition fabric area 13, the entire protective suit body 1 can fit more closely to the torso of the search and rescue dog, and the protective suit has better heat preservation performance.

[0072] Please see Figure 13 When the search and rescue dog's torso (the structure at the center of the diagram represents the dog's torso) needs to dissipate heat, gas is introduced into the inflatable air bag 5. The air bag 5 gradually expands, increasing the gap between the protective suit body 1 and the search and rescue dog's torso. During operation, airflow passes between the dog's torso and the protective suit body 1, facilitating heat dissipation. Although the increased gap between the protective suit and the dog, achieved through the inflation of the inflatable air bag 5, allows airflow and reduces heat buildup on the dog's surface, this also helps to reduce heat accumulation.

[0073] Please see Figure 7 and Figure 13 Preferably, inflatable air bags 5 can be symmetrically arranged on the inner surface of the protective suit body 1, wherein Figure 7 The inflatable airbag 5 is in an uninflated state, that is, in a flat state, while Figure 13 The inflatable air bags 5 are inflated. Because there is a certain distance between two adjacent inflatable air bags 5, and the gap between them after inflation forms a wind passage 6. The symmetrically arranged inflatable air bags 5 inflate symmetrically during actual inflation, and the main body 1 of the protective suit expands outward symmetrically. The inflation process is more balanced, and it is less likely to cause discomfort to the search and rescue dog due to uneven inflation.

[0074] In addition, some inflatable air bags 5 can be set on the inner surface 104 and located on both sides above the protective clothing frame 2. When the inflatable air bags 5 are inflated, they can provide two symmetrical support points for the body of the search and rescue dog. The protective clothing frame 2 extends along the length of the body of the search and rescue dog and can also be regarded as a third support point. The two inflatable air bags 5 and the protective clothing frame 2 together form the support system of the main body 1 of the protective clothing. The search and rescue dog can also be well supported and protected in case of collision and fall during the search and rescue process.

[0075] During actual search and rescue operations, search and rescue dogs may face various complex environments, such as collapsed buildings, exposed steel bars, and sharp glass. In actual search and rescue operations, the dogs are on their bellies, making them susceptible to scratches from sharp objects. If sharp objects cause abdominal injuries and damage internal organs, it can easily endanger their lives and health.

[0076] The protective suit body 1 of this embodiment of the invention is provided with a detection circuit for detecting damage to the protective suit body 1. The detection circuit can be arranged in the form of a circuit loop inside the protective suit body 1. Preferably, it can be glued to the inner surface of the outer layer 106 facing the middle layer 105, and the detection circuit is arranged in a roundabout manner, with both ends of the detection circuit electrically connected to a power source and a receiver.

[0077] When the detection circuit is in normal condition, meaning it is not damaged, the current flows normally inside the detection circuit, and the receiver electrically connected to the detection circuit receives a normally closed signal. If the surface material of the protective suit body 1 facing downwards is structurally damaged due to a sharp object, this damage may also cause structural damage or an open circuit in the circuit loop. The normally closed signal received by the receiver will then change to a normally open state. In practical applications, the integrity of the overall structure of the protective suit body is confirmed by the state change of the detection circuit.

[0078] Meanwhile, in the structure of the main body 1 of the protective suit, an inflatable air bag 5 can be set between the main body 1 of the protective suit and the surface of the search and rescue dog's body. By inflating the inflatable air bag 5, the volume of the inflatable air bag 5 expands, and the distance between the main body 1 of the protective suit and the surface of the search and rescue dog's body increases.

[0079] If the detection circuit is damaged by a sharp object, the signal received by the receiver from the detection circuit will change, which can serve as a start signal for the air pump to inflate the inflatable bag. It should be further noted that when the detection circuit signal changes from a normally closed state to a normally open state, the inflatable bag 5, after being inflated to a certain gas volume by the air pump, will be in a pressure-holding state and will not leak gas. If the inflatable bag is punctured by a sharp object while the search and rescue dog is continuing its search, causing gas leakage, a pressure sensor is installed in one of the pipes connected in series with the inflatable bag 5. If the pressure sensor detects a rapid depressurization of the inflatable bag 5, it sends a leak signal to the pressure detection device, which in turn sends a corresponding alarm signal, or sends an alarm reminder signal to the search and rescue dog's management personnel.

[0080] Example 4

[0081] In actual search and rescue operations, search and rescue dogs face various complex environments. Furthermore, it is necessary to improve search and rescue efficiency and shorten search and rescue time to more effectively increase the chances of rescuing survivors.

[0082] Please see Figure 14-17 The front of the protective suit body 1 of the present invention, corresponding to the area between the neck and heart of a search and rescue dog, has a marker release device 7 installed on its surface. The marker release device 7 includes a mounting housing 71, which is fixedly connected to the surface of the protective suit body 1, for example, by welding or bonding. The bottom surface 72 of the mounting housing 71 is provided with several release holes 73. The marker 8 used for marking the position is temporarily attached and released through the release holes 73. When it is necessary to release the marker 8 downward, the marker 8 is unlocked, and the corresponding marker 8 is released downward through the release holes 73 without being constrained.

[0083] The mounting housing 71 of the marker release device 7 has a cavity inside, and several marker placement housings 75 are located below the cavity. The bottom of the marker placement housing 75 is connected to the mounting housing 71 and has a release hole 73. The top of the marker placement housing 75 has a top hole 751. The top holes 751 of the several marker placement housings 75 are on the same straight line. The mounting housing 71 also contains a battery 76 and a servo motor 77. The battery 76 provides power to the servo motor 77. The rotation shaft of the servo motor 77 is connected to a rotating wheel 78. One end of a steel wire rope 79 is connected to the surface of the rotating wheel 78. The other end of the steel wire rope 79 passes through the top holes 751 of all the marker placement housings 75. When the marker 8 is installed inside the marker placement housing 75 and reaches the top limit position, the hanging hole 81 on the top of the marker and the top hole 751 of the marker placement housing 75 are on the same axis. The other end of the steel wire rope 79 also passes through the top hole 751 and the top hanging hole 81 of the marker placement housing 75.

[0084] More specifically, the marker 8 is cylindrical in shape, with a groove at the top and connected to a spring 82. The marker 8 has a hanging hole 81 at the top in the middle. The other end of the steel wire rope 79 can pass through the top hole 751 of the marker placement housing 75 and the hanging hole 81 in the middle of the marker 8 at the same time, so as to restrict the marker 8 inside the marker placement housing 75.

[0085] Preferably, when the top of the marker 8 moves upward and contacts the inner top surface of the marker placement housing 75, the central axis of the hanging hole 81 in the middle of the marker 8 and the central axis of the top hole 751 of the marker placement housing 75 are on the same horizontal plane.

[0086] More preferably, a foolproof structure is provided through the mutual cooperation between the marker 8 and the marker placement housing 75. For example, the outer peripheral surface of the marker 8 is provided with a protruding rib along the axial direction, and the inner wall surface of the marker placement housing 75 is provided with an inner groove along the axial direction. The marker 8 gradually moves upward along the marker placement housing 75, and the protruding rib and the inner groove cooperate with each other to move axially, which can prevent the marker 8 from rotating radially relative to the marker placement housing 75.

[0087] When search and rescue dogs are conducting search and rescue operations inside complex buildings, they may face various complex search and rescue environments. If the search and rescue dog notifies the search and rescue personnel by barking after finding a survivor, it may not be able to reliably transmit its sound outwards due to the complexity of the building, thus rendering the search and rescue dog's alert signal ineffective. Furthermore, if the search and rescue dog immediately retreats and notifies the search and rescue personnel after finding a survivor, it will waste valuable search and rescue time and exhaust the dog's energy.

[0088] Therefore, in this embodiment of the invention, a marker release device 7 is provided at the front of the protective suit body 1. When the search and rescue dog finds a survivor, it makes a preliminary judgment based on its daily training experience. At the same time, a push switch 74 is also provided on the surface of the marker release device 7. After the search and rescue dog finds and determines that the survivor is a survivor, it pushes the marker release device 7 forward, so that the push switch 74 is close to a nearby building or other obstacle. The push switch 74 is continuously pressed for a certain period of time, and the push switch 74 sends a start signal to the controller inside the marker release device 7. The controller controls the servo motor 77 to rotate a certain angle, so that the left end of the steel wire rope 79 moves a fixed distance to the right end. The left end of the steel wire rope 79 passes through the top hole 751 of the first marker placement housing 75 on the left and the hanging hole 81 in the middle of the marker 8. The marker 8 will not be constrained by the steel wire rope, and the marker 8 will be pushed outward by the pushing force of the spring 82. During the subsequent search and rescue operation, the controller was unlocked in sequence to release markers 8 at different locations and into the surrounding space of the survivors.

[0089] In other embodiments of the present invention, a sound sensor can be set in the controller inside the marker releaser 7. If the search and rescue dog finds a survivor during the actual search and rescue process, it can bark in a specific rhythm based on its experience in the daily training process, and the sound sensor can collect the sound as a detection signal before the marker 8 is released.

[0090] Alternatively, in other embodiments of the present invention, a heart rate sensor is provided on the inner surface of the protective suit body 1, and the heart rate sensor is positioned relative to the heart of the search and rescue dog. If the search and rescue dog finds a survivor during the actual search and rescue process, based on its experience from daily training, it barks at a specific rhythm, and the sound is collected by a sound sensor, converted from an analog signal to a digital signal, and recorded as high and low level signals. At the same time, the heart rate sensor detects the heart rate data of the search and rescue dog, for example, if the number of heartbeats in one minute exceeds a certain number, by combining the barking sound, rhythm, and heart rate change data of the search and rescue dog, it can be determined that the search and rescue dog has found a survivor.

[0091] It should be further explained that the marker 8 has a built-in circuit board 83, which is electrically connected to a battery 84. The circuit board 83 also contains a wireless connection module, such as a Bluetooth module. When the marker 8 is not yet released, the wireless connection module inside the marker 8 is electrically connected to the controller of the marker releaser 7 via radio. When the marker 8 is released, the switch 85 at the bottom of the marker 8 is activated by free fall to the ground. By recording the time, if the search and rescue dog carrying the marker releaser 8 moves to another location and exceeds a certain distance threshold, the wireless connection module inside the circuit board 83 switches from receiving to transmitting. Each time a marker releaser releases a marker, it sends a marking signal to the search and rescue personnel, such as a signal indicating activation or the location of the marked location. After marking the survivor's location, the search and rescue dog can continue subsequent search and rescue work, while the search and rescue personnel can quickly carry out subsequent search and rescue operations by combining the information from the dog's markings or the marked location information. More preferably, the main body of the marker is made of a light-transmitting material, and a ring-shaped indicator light 86 is provided inside the marker. If the marker 8 switches from receiving signal state to transmitting state, the indicator light 86 can be activated at the same time, so that the indicator light 86 changes to the lit state, making it convenient for search and rescue personnel to know the location of the marker 8 in a timely manner.

[0092] Example 5

[0093] Please see Figure 18 The multifunctional search and rescue dog auxiliary protection device of this invention also includes a foot cover 9 that is fitted onto the paw of the search and rescue dog. The foot cover 9 includes an upper foot cover body 91 and a foot cover sole 92. The top of the foot cover body 91 is provided with an inlet 911, and the paw of the search and rescue dog can pass through the top inlet 911 to enter the inside of the foot cover body 91 to wear it.

[0094] Additionally, a side ventilation opening 912 is provided on the upper front of the main body 91 of the foot cover, and a toe hole 913 is provided on the lower front of the main body 91 of the foot cover. Since the front of the search and rescue dog's paw has four toes, when the paw enters the main body 91 of the foot cover, the search and rescue dog's toes can extend outward through the toe hole 913, and the search and rescue dog's toes or nails can also partially contact the ground. In order to enable the search and rescue dog's toes to better contact the ground, the front of the sole 92 of the foot cover in this embodiment of the invention can be set as an inclined surface, or the front of the sole 92 of the foot cover can be set as a structure in which the thickness gradually decreases from front to back.

[0095] During actual search and rescue operations, search and rescue dogs, when not wearing special shoes, have their paws in direct contact with the ground to sense the terrain and identify objects they are stepping on. However, this direct contact makes their paws susceptible to the temperature of the ground. Excessive heat can burn their paws, while excessive cold can cause frostbite.

[0096] Please see Figure 19 In this embodiment of the invention, the bottom surface of the foot cover sole 92 is provided with a plurality of metal support blocks 921, and each metal support block 921 corresponds to the position of the search and rescue dog's paw. That is, the metal support blocks 921 can be divided into two types: one corresponds to the toes of the paw, and the other corresponds to the center of the paw. In addition, part of the metal support block 921 is embedded inside the foot cover sole 92, while the other part of the metal support block 921 is exposed downward to support the ground. After the search and rescue dog's paw is inserted into the foot cover, the paw has the foot cover sole 92 and the metal support blocks 921 arranged sequentially from top to bottom. During the search and rescue process, the search and rescue dog's paw will not directly contact the ground. By stepping on the metal support blocks 921, it can easily obtain information about the ground conditions. The foot cover sole 92 is provided between the metal support blocks 921 and the paw. The foot cover sole 92 can be made of plastic material to further improve the comfort of use. Alternatively, the soles of the foot covers (92) can be made of heat-insulating material to prevent the metal support blocks from transmitting heat upwards, thus affecting the comfort of the search and rescue dog during the search and rescue process.

[0097] Preferably, the inner side of the foot cover body 91 is provided with a plurality of grooved ventilation channels 914, wherein the ventilation channels 914 extend from the front of the foot cover body 91 to the rear, and a through hole 915 is provided on the back of the foot cover body 91, and the through hole 915 passes directly through the foot cover body 91.

[0098] During actual search and rescue operations, the air at the front of the foot cover circulates from front to back through the ventilation duct 914 and then dissipates heat through the through hole 915. In practical applications, search and rescue dogs typically move forward, such as by running. Therefore, the air pressure at the back of the foot cover 9 is lower than the air pressure at the front. As the search and rescue dog moves forward while wearing the foot cover 9, the air at the front of the foot cover flows from front to back through the ventilation duct 914, thus transporting the hot air between the foot cover and the dog's foot to the rear and outward through the through hole 915.

[0099] When search and rescue dogs are conducting search and rescue operations in cold environments, extra attention should be paid to keeping their feet warm when wearing foot covers 9. Therefore, in addition to the foot cover body 91 mentioned above, an inner cover 94 needs to be placed on the dog's feet. The inner cover 94 is directly fitted onto the dog's feet, and its outer surface is provided with a meandering sealed air tube 941. The sealed air tube 941 can be arranged from top to bottom and is designed as a multi-layered structure, with each layer allowing air to pass through from top to bottom. Therefore, macroscopically, the sealed air tube 941 is a continuous and meandering strip-shaped air bag structure. When the inner cover 94 is fitted onto the surface of the dog's feet, the feet and the inner cover 94 simultaneously enter the interior of the foot cover body 91, and the sealed air tube 941 is tightly fitted with the ventilation duct 914, thus stopping the air from moving backward inside the foot cover body 91. At the same time, since the sealed air tube 941 can deform to a certain extent and cooperate with the ventilation duct 914, the multi-layered ventilation duct 914 can also restrict the inner sleeve 94 from moving outward, and the search and rescue dog's feet can also be tightly connected to the foot cover 9 through the inner sleeve 94.

[0100] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
