Description

Technical Field

[0001] The present invention relates to the technical field of search and rescue dog equipment, and particularly relates to a multifunctional auxiliary protection device for search and rescue dogs. Background Art

[0002] When disasters such as earthquakes and fires occur, it is very necessary to search for survivors in a timely manner. However, in the face of building collapses caused by earthquakes, it is very challenging for search and rescue personnel to directly penetrate into the complex collapsed buildings for search and rescue. Since the human body is relatively larger than that of a search and rescue dog, it is difficult to flexibly pass through small-sized spaces or channels, which will greatly increase the difficulty of search and rescue. However, when using search and rescue dogs for search and rescue operations, the flexible body of the search and rescue dog will reduce the difficulty of search and rescue, and the search and rescue dog has a sensitive sense of smell, which will greatly increase the probability of finding survivors. In addition, when using search and rescue dogs to search for survivors in a fire environment, since the search and rescue dog walks with its legs touching the ground at the same time, it effectively avoids search and rescue personnel directly entering the fire scene and easily inhaling the thick smoke at the high places in the search space.

[0003] However, when a search and rescue dog directly enters a building collapse or a fire scene, it faces a complex environment, such as exposed steel bars, broken glass, sharp wooden blocks, etc. During the actual search and rescue process, the search and rescue dog may pass through narrow paths. If there are the above-mentioned dangerous objects on the path it passes through, it will cause harm to the body of the search and rescue dog. Moreover, the abdomen of the search and rescue dog is directly downward. If a sharp dangerous object causes harm to the abdomen of the search and rescue dog, it is often a relatively serious injury, even threatening its life and health. For the existing search and rescue dog auxiliary equipment, protective clothing is usually directly wrapped on the surface of the search and rescue dog's body. Although it can protect the surface of its body, during the running process of the search and rescue dog, the protective clothing is prone to displacement, resulting in the abdomen of the search and rescue dog not being effectively protected. In addition, if the internal structure of the protective clothing is damaged or the structure of the protective clothing is damaged by sharp dangerous objects, there is no corresponding alarm prompt or additional protection, which will pose a serious threat to the life and health of the search and rescue dog.

[0004] In addition, when a search and rescue dog is actually searching and rescuing, it may face high-temperature or low-temperature environments. When in a high-temperature environment, the paws of the search and rescue dog directly touch the high-temperature ground and are baked by the high temperature. When in a low-temperature environment, the paws of the search and rescue dog directly touch the ground and are easily frozen, thus affecting the actual search and rescue sensitivity of the search and rescue dog. Summary of the Invention

[0005] The main object of the present invention is to propose a multifunctional search and rescue dog auxiliary protection device, aiming to effectively solve the technical problems encountered in the search and rescue work of search and rescue dogs, so that the abdomen of the search and rescue dog can be well protected, and for different application scenarios, heat dissipation or warming can be appropriately carried out, and in the face of damage to the protective clothing, timely detection and an inflatable airbag for further protection are provided, and the feet of the search and rescue dog are further protected by cooperating with the application of foot covers.

[0006] To achieve the above object, a multifunctional search and rescue dog auxiliary protection device proposed by the present invention includes a protective clothing main body, and a protective clothing support is provided on the bottom surface of the protective clothing main body. When the protective clothing main body is connected to the torso of the search and rescue dog, the protective clothing support supports the protective clothing main body to cooperate with the surface shape of the torso of the search and rescue dog.

When the inflatable airbags are in a non-inflated state, the inflatable airbags are located in the space between the protective clothing main body and the torso of the search and rescue dog, and the inflatable airbags support different positions of the torso of the search and rescue dog; when the inflatable airbags are in an inflated state, the inflatable airbags push the protective clothing main body away from the torso of the search and rescue dog, and form a channel for gas to flow along the front and back directions of the protective clothing main body. The inflatable airbags on the left and right sides and the protective clothing support together form a triangular support system for supporting the torso of the search and rescue dog.

[0011] Preferably, a detection circuit for detecting the damage condition of the protective clothing body is provided inside the protective clothing body, and the detection circuit is arranged in a meandering manner; when the protective clothing body is damaged and the detection circuit is open-circuited, the inflatable airbag enters the inflated state; the inflatable airbag is connected to a sensor for detecting air pressure.

[0012] Preferably, a marker releaser is provided at the front part of the protective clothing body. There is a cavity inside the marker releaser. Several marker placement shells are provided below the cavity inside. The bottom of the marker placement shell is connected to the installation shell and is provided with a release hole.

There are protruding ribs along the axial direction on the outer peripheral surface of the marker, and inner grooves are axially provided on the inner wall surface of the marker placement shell. As the marker gradually moves upward along the marker placement shell, the protruding ribs and the inner grooves cooperate with each other to move axially, which can prevent the marker from rotating radially relative to the marker placement shell.

[0014] Preferably, the multifunctional search and rescue dog auxiliary protection device further includes a foot cover sleeved on the position of the search and rescue dog's foot. The foot cover includes a foot cover main body and a foot cover sole at the upper part.

[0044] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] The present invention provides a multifunctional search and rescue dog auxiliary protection device.

[0047] Embodiment 1

[0048] Please refer to Figure 1-4 , in the multifunctional search and rescue dog auxiliary protection device of the embodiment of the present invention, it includes a protective clothing main body 1. A protective clothing support 2 is provided on the bottom surface of the protective clothing main body 1. When the protective clothing main body 1 is connected to the torso of the search and rescue dog, the protective clothing support 1 cooperates with and positions the surface shape of the torso of the search and rescue dog.

[0049] Specifically, the protective clothing support 2 of the embodiment of the present invention is in a plate-like structure. The top surface 21 of the protective clothing support 2 is connected to the bottom surface of the protective clothing main body 1 and can be connected by bonding or other forms. Since the search and rescue dog has an outwardly convex shape on the surface from front to back at the abdominal position, the top surface 21 of the protective clothing support 2 of the embodiment of the present invention is an inwardly concave curved surface 22. When the protective clothing main body 1 is connected to the abdominal surface of the search and rescue dog, the protective clothing support 2 on the outer surface of the protective clothing main body 1 has both ends protruding upward and the middle part sunken downward. Therefore, the protective clothing support 2 can upwardly support the protective clothing main body 1, and the protective clothing main body 1 fits better with the body of the search and rescue dog. And when the protective clothing main body and the search and rescue dog are attached and connected, the positional relationship from top to bottom is the body of the search and rescue dog, the protective clothing main body 1, and the protective clothing support 2.

[0050] Please refer to Figure 3 and 4 , preferably, the protective clothing support 2 of the embodiment of the present invention is in a plate body structure. After the protective clothing main body 1 is worn on the surface of the search and rescue dog's body, the protective clothing main body 1 is upwardly supported by the protective clothing support 2 to cooperate with the surface of the search and rescue dog's body, so that the protective clothing main body 1 fits better with the surface of the torso of the search and rescue dog. The protective clothing support 2 can be made of carbon fiber material to achieve overall light weight and good wear resistance.

[0051] Please refer to Figure 2 and 3 , since the search and rescue dog may fold and bend its legs and compress its body posture downward during the actual search and rescue process, the main body of the protective clothing support 2 of the embodiment of the present invention is made of a deformable material and is in a split structure.

[0052] Specifically, since the protective clothing support 2 of the embodiment of the present invention is in an overall long strip shape, a first transition material 23 is provided at the middle position of the protective clothing support 2 along the first direction, and a second transition material 24 is provided at the middle in the second direction. The protective clothing support 2 is divided into several structural blocks by the first transition material 23 and the second transition material 24. The several structural blocks are not directly connected and are indirectly connected through the first transition material 23 or the second transition material 24. For example, in the embodiment of the present invention, the protective clothing support 2 is divided into four structural blocks by the first transition material 23 and the second transition material 24.

[0053] At the same time, the first transition material 23 and the second transition material 24 are made of elastic material, and the elasticity of the first transition material 23 and the second transition material 24 is greater than the elasticity of the structural block. The entire protective clothing bracket 2 is produced by double-color injection molding, that is, the first transition material 23 and the second transition material 24 of the embodiment of the present invention divide the protective clothing bracket 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 be elastically deformed, and the four structural blocks can swing relative to each other, move relative to each other, and the search and rescue dog changes the overall shape of the protective clothing bracket 2 from the original concave structure to a flat plate structure, or other changes during the actual operation. During the actual rescue process, the search and rescue dog compresses its posture downward, and the four structural blocks can swing relative to each other, changing to a connection shape that is approximately flat. This can protect the abdomen of the search and rescue dog and also enable it to easily pass through channels of different shapes during the actual search and rescue process, which is more in line with its actual search and rescue work needs. In addition, in other embodiments of the present invention, in addition to the appended claims of the present invention, Figure 2 、 3 The cross-intersecting first transition material 23 and the second transition material 24 are shown. More transition materials can be provided to form a cross-shaped intermediate connection structure system to achieve the purpose of dispersing the protective clothing support 2 into more structural blocks.

[0054] See Figure 1 The protective suit main body 1 is provided with side positioning grooves 101 adapted to the legs of the search and rescue dog, wherein the side positioning grooves 101 have outward openings. When the protective suit main body 1 is connected to the torso of the search and rescue dog, the legs of the search and rescue dog are inserted into the side positioning grooves 101 along the openings of the positioning grooves 101, and then the protective suit main body 1 is pulled or shifted toward the head or tail of the search and rescue dog, so that the connection relationship between the protective suit main body 1 and the search and rescue dog can be more accurate and tightly fitted.

[0055] Example 2

[0056] See Figure 5-6, in the embodiments of the present invention, a positioning ring 102 may be connected to the side of the side positioning groove 101. A central through hole 103 is provided in the center of the positioning ring 102. When the search and rescue dog wears the protective clothing main body 1, by inserting its four limbs into the central through hole 103 of the positioning ring 102 and then cooperating with a connecting band (not marked in the figure) provided at the edge position of the protective clothing main body 1, and a buckle is provided at the end of the connecting band, it is convenient to realize the quick wearing of the protective clothing main body 1 and the search and rescue dog, and through the connecting band and the buckle, the protective clothing main body 1 and the search and rescue dog's body are fixedly connected. When the protective clothing main body 1 and the search and rescue dog are worn, it is not easy to shift. The positioning ring 102 can be made of an elastic material, and the positioning ring 102 has a higher degree of fitting connection with the dog's leg. Preferably, the positioning ring 102 is connected to the bottom surface part of the protective clothing main body 1.

[0057] Embodiment 3

[0058] During the actual search and rescue process, search and rescue dogs often face high-temperature or low-temperature environments. When a search and rescue dog conducts search and rescue in a high-temperature environment, it needs to have good heat dissipation conditions, while in a low-temperature environment, it needs to have good heat preservation conditions.

[0059] Please refer to Figure 7 , 8 , the protective clothing main body 1 of the embodiments of the present invention is a three-layer structure, mainly including an inner surface layer 104, an intermediate layer 105, and an outer surface layer 106 from the inside out. The intermediate layer 105 is arranged between the inner surface layer 104 and the outer surface layer 106. The intermediate layer 105 can move relatively or be fixed in the space between the inner surface layer 104 and the outer surface layer 106, and the inner surface layer 104, the intermediate layer 105, and the outer surface layer 106 together form the main structure of the protective clothing main body 1.

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

[0061] Please refer to Figure 9 , in addition, a ventilation area 1051 and a sealing area 1052 are provided on the surface of the intermediate layer 105. When the intermediate layer 105 moves relatively with the inner surface layer 104 and the outer surface layer 106, the relative positions of the ventilation area 1051 and the sealing area 1052 with respect to the ventilation holes 107 change.

[0062] When a search and rescue dog conducts search and rescue in a high-temperature environment, by aligning the ventilation area 1051 on the surface of the middle layer 105 with the ventilation holes 107 on the surfaces of the inner layer 104 and the outer layer 106, the hot air or heat between the search and rescue dog and the main body 1 of the protective clothing is released outward through the ventilation area 1051 and the ventilation holes 107. If the search and rescue dog needs to conduct search and rescue work in a cold environment, by aligning the sealing area 1052 with the ventilation holes 107, the ventilation holes 107 can be covered to prevent excessive heat loss from the surface of the search and rescue dog's body, achieving a heat preservation effect.

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

[0064] Please refer to Figure 9-12 , preferably, since the middle layer 105 is provided between the inner layer 104 and the outer layer 106, and the ventilation area 1051 and the sealing area 1052 provided on the surface of the middle layer 105 need to move their positions to achieve the switching between the heat preservation and ventilation functions, several fixing parts 3 are provided on the outer layer 106, and several movable parts 4 are connected to the middle layer 105. The movable parts 4 can move relative to and be fixed to the fixing parts 3. After the connection position is determined, the movable parts 4 and the fixing parts 3 are fixedly connected to fix the connection position between the middle layer 105 and the outer layer 106.

[0065] Specifically, the fixing part 3 of the embodiment of the present invention is provided on the surface of the outer layer 106. A channel 31 is provided inside the fixing part 3, and an opening 32 is provided on the surface of the fixing part 3. Several positioning holes 33 are spaced at different positions inside the channel 31 of the fixing part 3. The main body 41 of the movable part 4 of the embodiment of the present invention is in a strip structure, and the main body 41 of the movable part 4 is matched with the channel 31 inside the fixing part 3, that is, the main body of the movable part 4 can move back and forth along the channel 31 inside the fixing part 3. Two positioning blocks 42 are provided at both ends of the main body 41 of the movable part 4, and the positioning blocks 42 are connected to the positioning holes 33 in a positioning and plugging manner.

[0066] Further, it should be noted that the width dimension of the positioning hole 33 of the fixing member 3 is greater than the width dimension of the channel 31, and the width dimension of the positioning block 42 of the movable member 4 is greater than the width dimension of the main body 41 of the movable member 4. Therefore, by mating the positioning block 42 of the movable member 4 with the positioning holes 33 at different positions, the connection relationship between the movable member 4 and the fixing member 3 at different positions can be achieved. In addition, the main body of the movable member 4 is provided with a protruding block 43 extending outward. A part of the structure of the protruding block 43 passes through the channel 31 and extends outward. The bottom of the main body 41 of the movable member 4 is provided with a bottom connecting block 44, and the bottom connecting block 44 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 an elastic material. Therefore, the bottom connecting block 44 can be elastically pulled outwards, so that the intermediate layer 105 can move relative to the inner surface layer 104 and the outer surface layer 106, and can be reset when not elastically pulled out, so that the movable member 4 and the fixing member 3 are relatively 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, by pulling out the protruding block 43 out of the channel 31, and pulling the protruding block 43 to move relative to the channel 31, finally select a suitable positioning hole 33, and then press the positioning block 42 into the positioning hole 33 at the new position, the different connection positions of the positioning block 42 and the positioning hole 33 can be conveniently adjusted, the different connection positions of the intermediate layer 105 with the inner surface layer 104 and the outer surface layer 106 can be adjusted, and the different matching positions or relationships between the ventilation area 1051 or the sealing area 1052 and the ventilation holes 107 can be adjusted.

[0068] During the actual rescue process of search and rescue dogs, when searching and rescuing in a high-temperature environment, it is necessary to achieve good air permeability between the protective clothing and the body of the search and rescue dog. In a low-temperature environment, it is necessary to make it have good heat preservation performance.

[0069] Please refer to Figure 7 , in the present invention, the protective clothing applied to search and rescue dogs includes a protective clothing main body 1 and a protective clothing strap connecting member (not shown in the figure). The protective clothing main body 1 mainly fits on the abdominal position of the search and rescue dog to protect the abdominal position of the search and rescue dog. The protective clothing strap connecting member can extend upward in a buckle manner and is connected on the back of the search and rescue dog, so that the protective clothing can be reliably connected to the torso of the search and rescue dog.

[0070] Preferably, elastic transition fabric areas are provided on both sides of the protective clothing body, and through the elastic transition fabric areas, the protective clothing straps can be connected to the protective clothing body 1. The force transmission path from the protective clothing straps to the protective clothing body must pass through the elastic transition fabric areas, and the elastic transition fabric areas can perform elastic stretching. When the protective clothing is connected to the torso of the search and rescue dog, through the elastic transition fabric areas, longitudinal elongation or shortening can be performed, and the protective clothing body 1 can be applicable to search and rescue dogs of different sizes, and the protective clothing body 1 is reliably and closely connected to the torso of the search and rescue dog.

[0071] Meanwhile, a plurality of inflatable air bags 5 are provided on the surface of the inner surface layer 104 of the protective clothing body 1. The inflatable air bags 5 are made of soft materials. When the inflatable air bags 5 are in a non-inflated state, the inflatable air bags 5 are attached to the surface of the protective clothing body 1. Cooperating with the elastic transition fabric area 13, it can make the entire protective clothing body 1 fit better with the torso of the search and rescue dog, and the protective clothing has better heat preservation performance.

[0072] Please refer to Figure 13 , if the torso of the search and rescue dog (the central structure in the figure is the torso of the search and rescue dog) needs to dissipate heat, then gas is filled into the inflatable air bags 5. The volume of the inflatable air bags 5 gradually expands, and the gap between the protective clothing body 1 and the torso of the search and rescue dog increases. During the movement of the search and rescue dog, the flowing wind passes through the gap between the surface of the torso of the search and rescue dog and the protective clothing body 1 to dissipate heat from its surface. Although in the actual heat dissipation process of dogs, by inflating the inflatable air bags 5, the gap between the protective clothing and the search and rescue dog is increased, and the wind flows through this gap, which can also play a role in reducing the heat accumulation on the body surface of the search and rescue dog.

[0073] Please refer to Figure 7 and Figure 13 , preferably, the inflatable air bags 5 can be symmetrically arranged on the inner surface of the protective clothing body 1, where Figure 7 the inflatable air bags 5 are in a non-inflated state, that is, a flat state, while Figure 13 the inflatable air bags 5 are in an inflated state. Since there is a certain distance between two adjacent inflatable air bags 5, and after the inflatable air bags 5 are inflated, the gap between them forms a wind flow channel 6. When the symmetrically arranged inflatable air bags 5 are in an actual inflated state, they are inflated symmetrically, and the entire protective clothing body 1 expands outward symmetrically. The inflation process is more balanced, and it is not easy to make the search and rescue dog uncomfortable due to unbalanced inflation.

[0074] In addition, some inflatable airbags 5 can be arranged on the surface of the inner surface layer 104 and on both sides above the protective clothing support 2. When the inflatable airbags 5 are in an inflated state, two symmetrical support points can be generated on the body of the search and rescue dog. The protective clothing support 2 is arranged along the length direction of the body of the search and rescue dog and can also be regarded as a third support point. The two inflatable airbags 5 and the protective clothing support 2 together form the support system of the protective clothing main body 1. When the search and rescue dog collides and falls during the search process, good support and protection can also be achieved.

[0075] During the actual search process of the search and rescue dog, the search and rescue dog may face various complex environments, such as collapsed buildings, exposed steel bars, sharp glass, etc. During the actual search process, the search and rescue dog lies on its stomach, and it is easy to be scratched by sharp objects on its abdomen. Moreover, when the sharp object causes injury to its abdomen and its internal organs, its life and health are easily endangered.

[0076] The protective clothing main body 1 of the embodiment of the present invention is internally provided with a detection circuit for detecting the damage condition of the protective clothing main body 1, and the detection circuit can be arranged in the protective clothing main body 1 in the form of a circuit loop. Preferably, it can be adhesively bonded to the inner surface of the outer surface layer 106 facing the intermediate layer 105, and the detection circuit is arranged in a circuitous manner, and both ends of the detection circuit are electrically connected to the power supply and the receiver at the same time.

[0077] When the detection circuit is in a normal state, that is, when there is no damage, the current inside the detection circuit flows normally, and the signal received by the receiver electrically connected to the detection circuit is a normally closed signal. If the surface material of the protective clothing main body 1 facing down is structurally damaged due to sharp objects, this damage may also cause structural damage or open circuit in the circuit loop, and the normally closed signal received by the receiver is converted into an open state. In practical applications, the integrity of the overall structure of the protective clothing main body is confirmed by the state change of the detection circuit.

[0078] At the same time, in the structure of the protective clothing main body 1, a corresponding inflatable airbag 5 can be arranged between the protective clothing main body 1 and the body surface of the search and rescue dog. By inflating the inflatable airbag 5, the volume of the inflatable airbag 5 expands, and the distance between the protective clothing main body 1 and the body surface of the search and rescue dog increases.

[0079] If the detection circuit is damaged due to a sharp object, the signal received by the receiver from the detection circuit changes, which can be used as a start signal for the inflatable pump to inflate the inflatable airbag. It should be further noted that when the detection signal of the detection circuit changes from the normally closed state to the normally open signal, after the inflatable airbag 5 is inflated by the inflatable pump and inflated to a certain gas volume, the inflatable airbag will be in a pressure-holding state and will not leak gas outward. When the search and rescue dog continues the search, if the inflatable airbag is scratched by a sharp object, there will be gas leakage in the inflatable airbag 5. Therefore, a pressure sensor for pressure detection is provided in a certain pipeline of the inflatable airbag 5 connected by a series pipeline. If the pressure sensor detects that there is a rapid pressure relief in the inflatable airbag 5, a leakage gas signal will be sent to the pressure detection device, and then a corresponding alarm signal will be sent, or a corresponding alarm reminder signal will be sent to the manager of the search and rescue dog.

[0080] Embodiment 4

[0081] During the actual search process of the search and rescue dog, the search and rescue dog faces various complex environments. And during the search process of the search and rescue dog, it is necessary to improve the search efficiency and shorten the search time in order to more effectively increase the chance of survival of the survivors.

[0082] Please refer to Figure 14-17 , in the front part of the protective clothing main body 1 of the present invention, corresponding to the position between the neck and the heart of the search and rescue dog, a marker releaser 7 is installed on the surface of the protective clothing main body 1. The marker releaser 7 includes an installation housing 71, and the installation housing 71 is fixedly connected to the surface of the protective clothing main body 1, such as fixedly connected by welding, bonding, etc. A plurality of release holes 73 are provided on the bottom surface 72 of the installation housing 71, and the marker 8 for marking the position is temporarily hung and released through the release holes 73. When it is necessary to release the marker 8 downward, by unlocking the marker 8, the corresponding marker 8 is not restricted and is released downward through the release holes 73.

[0083] Inside the installation housing 71 of the marker releaser 7, there is a cavity. Below the cavity, there are several marker placement housings 75. The bottom of the marker placement housing 75 communicates with the installation housing 71 and is provided with a release hole 73. And the upper part of the marker placement housing 75 is provided with a top hole 751. The top holes 751 of several marker placement housings 75 are on the same straight line. Inside the installation housing 71, there is also a battery 76 and a servo motor 77. The battery 76 provides power for the servo motor 77. The rotating 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. And when the marker 8 is installed inside the marker placement housing 75 and reaches the top limit position, the hanging hole 81 at 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 will also pass through the top hole 751 of the marker placement housing 75 and the hanging hole 81 at the top of the marker.

[0084] More specifically, the marker 8 is integrally cylindrical. The top of the marker 8 is provided with a groove and is connected with a spring 82. The middle part of the marker 8 is provided with a hanging hole 81 at the top of the marker. 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 to limit the marker 8 inside the marker placement housing 75.

[0085] Preferably, when the top end 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, an anti-fooling structure is provided through the mutual cooperation relationship between the marker 8 and the marker placement housing 75. For example, convex ribs are provided along the axial direction on the outer peripheral surface of the marker 8, and inner grooves are provided along the axial direction on the inner wall surface of the marker placement housing 75. As the marker 8 gradually moves upward along the marker placement housing 75, the convex ribs and the inner grooves 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 a search and rescue dog conducts search and rescue in a complex building, the search and rescue dog may face various complex search and rescue environments. If the search and rescue dog finds a survivor and notifies the search and rescue personnel in the form of barking, it is easy to be unable to reliably transmit the sound outward because it is deep inside the complex building, resulting in the reminder signal of the search and rescue dog being unable to play its due role. And because the search and rescue dog finds a survivor and immediately retreats and notifies the search and rescue personnel, it will waste precious search and rescue time and consume the physical energy of the search and rescue dog.

[0088] Therefore, in the embodiment of the present invention, a marker release device 7 is provided at the front part of the protective clothing main body 1. When the search and rescue dog finds a survivor, the search and rescue dog initially judges whether it is a survivor according to its daily training experience. At the same time, a push switch 74 is also provided on the surface of the marker release device 7. When the search and rescue dog finds and judges that it is a survivor, by pushing the marker release device 7 forward, the push switch 74 is brought close to a nearby building or other obstacles, so that the push switch 74 is continuously pressed within a certain period of time. 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 to the right end by a fixed dimension. The left end of the steel wire rope 79 passes through the top hole 751 of the leftmost marker placement housing 75 and the hanging hole 81 in the middle of the marker 8. The marker 8 will no longer be restricted by the steel wire rope, and the marker 8 is pushed outwards by the pushing force of the spring 82. During the subsequent search and rescue process, the controller unlocks in sequence to release the markers 8 at different positions and release them to the surrounding space position of the survivor.

[0089] In other embodiments of the present invention, a sound sensor can be provided in the controller inside the marker release device 7. If the search and rescue dog finds a survivor during the actual search and rescue process, based on its daily training experience, it barks according to a specific rhythm, and the sound is collected by the sound sensor to be used as a detection signal before the marker 8 is released.

[0090] Or in other embodiments of the present invention, a heart rate sensor is provided on the inner surface of the protective clothing main body 1, and the heart rate sensor is arranged relative to the heart position 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 daily training experience, it barks according to a specific rhythm, and the sound is collected by the sound sensor and 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 per minute exceeds a specific number, by combining the barking sound, rhythm and heart rate change data of the search and rescue dog, it can be judged that the search and rescue dog has found a survivor.

[0091] It should be further noted that the marker 8 is internally provided with a circuit board 83, and the circuit board 83 is electrically connected to a battery 84. And a wireless connection module, such as a Bluetooth module, is provided inside the circuit board 83. When the marker 8 is in the state of not being released, the wireless connection module inside the marker 8 is electrically connected to the controller of the marker release device 7 in a radio connection manner. When the marker 8 is released, the bottom switch 85 of the marker 8 drops to the ground by free fall and is activated. By recording the time, if the search and rescue dog carrying the marker release device 8 moves to other positions and exceeds a certain distance threshold, the wireless connection module provided inside the circuit board 83 switches from the receiving state to the transmitting state. And when each marker release device releases a marker, it will send a marker signal to the search and rescue personnel, such as the signal after being activated, or the position signal of the marked location, etc. After the search and rescue dog marks the position of the survivor, it can continue to carry out the subsequent search and rescue work, while the search and rescue personnel can quickly carry out the subsequent search and rescue work by combining the marker information of the search and rescue dog or the marked position information. More preferably, the main material of the marker is selected as a light-transmitting material, and an annular display lamp 86 is provided inside the marker. If the marker 8 switches from the receiving signal state to the transmitting state, the display lamp 86 can be activated at the same time, so that the display lamp 86 changes to the lit state, which is convenient for the search and rescue personnel to timely know the location of the marker 8.

[0092] Embodiment 5

[0093] Please refer to Figure 18 , the multifunctional search and rescue dog auxiliary protection device of the embodiment of the present invention further includes a foot sleeve 9 sleeved on the position of the search and rescue dog's paw. The foot sleeve 9 includes a foot sleeve main body 91 and a foot sleeve sole 92 at the upper part. An entrance 911 is provided at the top of the foot sleeve main body 91, and the paw of the search and rescue dog can pass through the entrance 911 at the top and enter the inside of the foot sleeve main body 1 to achieve wearing.

[0094] In addition, a side ventilation opening 912 is provided above the front part of the foot sleeve main body 91, and a toe through hole 913 is provided below the front part of the foot sleeve main body 91. Since there are four toes at the front part of the paw of the search and rescue dog, when the paw enters the inside of the foot sleeve main body 91, the toes of the search and rescue dog can pass through the toe through hole 913 and extend outwards, and the toes or nails of the search and rescue dog can also partially contact the ground. In order to enable the toes of the search and rescue dog to better contact the ground, the front part of the foot sleeve sole 92 of the embodiment of the present invention can be set as an inclined surface, or the front part of the foot sleeve sole 92 is set in a structural form with a gradually decreasing thickness from front to back.

[0095] During the actual search and rescue process, in order to sense the ground conditions, when the search and rescue dog is not wearing special shoes, the lowest position of the dog's paw contacts the ground to obtain information about the trampled objects. However, if the dog's paw directly contacts the ground, it is vulnerable to the temperature of the ground. When the temperature is too high, it is easy to scald the dog's paw, or when the temperature is too low, it will frostbite the dog's paw.

[0096] Please refer to Figure 19 , on the bottom surface of the sole 92 of the foot cover in the embodiment of the present invention, there are provided several metal support blocks 921, and each metal support block 921 corresponds to the position of the dog's paw. That is, the metal support blocks 921 can be divided into two types. One type corresponds to the toes of the paw, and the other type corresponds to the center of the paw. In addition, part of the structure of the metal support block 921 is embedded inside the sole 92 of the foot cover, and the other part of the structure of the metal support block 921 is exposed downward to support on the ground. After the dog's paw penetrates into the foot cover, the sole 92 of the foot cover and the metal support block 921 are successively arranged from top to bottom on the paw. During the search and rescue process, the dog's paw does not directly contact the ground. By stepping on the metal support block 921, it is convenient to obtain information about the ground conditions. And there is a sole 92 of the foot cover between the metal support block 921 and the paw. The sole 92 of the foot cover can be made of plastic material to further improve the use comfort. Or the sole 92 of the foot cover is made of heat-insulating material to prevent the metal support block from transferring heat upward and affecting the working comfort during the search and rescue process of the dog.

[0097] Preferably, on the inner side surface of the foot cover main body 91, there are provided several ventilation air ducts 914 with inner grooves. The ventilation air ducts 914 extend from the front part to the back part of the foot cover main body 91, and a through hole 915 is provided on the back of the foot cover main body 91, and the through hole 915 directly penetrates through the foot cover main body 91.

[0098] During the actual search and rescue process of the dog, the air in the front part of the foot cover can flow from the ventilation air duct 914 from front to back, and then pass through the through hole 915 for heat dissipation. In the actual application process, when the dog conducts search and rescue, it usually moves forward, such as running. Therefore, the air pressure at the back position of the foot cover 9 is less than the air pressure at the front position of the foot cover 9. Therefore, as the dog wears the foot cover 9 and moves forward, the air in the front part of the foot cover can pass through the ventilation air duct 914 and flow from the front part to the back part, thereby transporting the hot air between the foot cover and the dog's foot to the back part and flowing out through the through hole 915.

[0099] When a search and rescue dog conducts search and rescue in a cold environment and wears the foot cover 9, more attention should be paid to the warmth preservation of the dog's feet. Therefore, in addition to applying the above-mentioned foot cover main body 91, an inner cover 94 needs to be put on the dog's foot position. The inner cover 94 is directly sleeved on the dog's foot position, and a meandering sealing air pipe 941 is arranged on the outer surface of the inner cover 94. The sealing air pipe 941 can be arranged from top to bottom and is set as a multi-layer structure, and each layer structure is in an up-and-down ventilation mode. Therefore, macroscopically, the sealing air pipe 941 is a continuous and meandering strip-shaped air bag structure. After the inner cover 94 is sleeved on the dog's foot surface, the foot and the inner cover 94 enter the inside of the foot cover main body 91 at the same time, and the sealing air pipe 941 is closely attached to the ventilation air duct 914, so that the air inside the foot cover main body 91 stops moving backward. At the same time, since the sealing air pipe 941 can be deformed to a certain extent and cooperate with the ventilation air duct 914, the multi-layer ventilation air ducts 914 up and down can also limit the outward movement of the inner cover 94, and the dog's foot can also be closely connected to the foot cover 9 through the inner cover 94.

[0100] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
