Description

Technical Field

[0001] This invention belongs to the field of life search and rescue technology, specifically relating to an intelligent life search and rescue device and method under landslide burial conditions. Background Technology

[0002] Landslides refer to the natural phenomenon where soil or rock masses on a slope slide downhill, either as a whole or in parts, under the influence of factors such as river erosion, groundwater activity, rainwater soaking, earthquakes, and artificial slope cutting, under the action of gravity along a certain weak surface or weak zone. Landslides can bury buildings and living beings, causing great harm. In order to achieve rapid rescue of lives, highly intelligent life-finding devices are used to detect life signals under buried bodies, such as radar life detectors. These radar life detectors are mainly made using the principle of electromagnetic wave reflection. They can detect ultra-low frequency radio waves emitted by the human heart within 30 seconds and can penetrate obstacles for detection. Relying on active detection, radar life detectors are not easily affected by adverse factors such as temperature, humidity, noise, and site terrain, effectively overcoming some technical defects of acoustic, optical, and infrared life detectors.

[0003] Existing life search and rescue devices require the installation of the main unit's battery during use. After use, the battery is removed and stored again to ensure its lifespan and prevent aging. However, the existing battery cover is usually fixed by hand-tightening bolts. This connection method is not only time-consuming, but also prone to thread stripping during frequent disassembly and assembly, which can lead to connection problems later on. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent life search and rescue device and method under landslide burial conditions, so as to solve the problem mentioned in the background art that the existing battery cover cannot be quickly disassembled.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent life search and rescue device under landslide burial conditions, comprising a shell and a detection component disposed inside the shell for detecting living beings. The detection component consists of a handheld tablet and a detection host wirelessly connected, eliminating the need for a data cable connection and facilitating data transmission. The detection host has a battery compartment, and a battery that is detachably inserted into the battery compartment is placed inside the shell. A battery cover is also provided on the top of the battery compartment. Both ends of the battery cover are provided with connecting components that connect to the detection host. The connecting components consist of a limiting component and a buffer component. The limiting component includes a rotating column penetrating the battery cover for rotational locking, with a smooth surface. A hook is formed on one side of the bottom end of the rotating column to achieve limiting locking. A limiting hole for the hook to engage is provided on the top of the detection host. A through hole is also provided on the top of the battery cover. Liquid is injected into the through hole, and the buffer component floats on the liquid inside the through hole, achieving subsequent limiting through buoyancy. The top of the limiting component is in contact with the rotating column.

[0006] Preferably, the buffer assembly includes a stop block and a foam block arranged from top to bottom. The foam block has buoyancy, and the bottom end of the foam block has multiple receiving cavities. At least one sealing ring is sleeved on the outer side of the foam block, and the outer diameter of the sealing ring fits seamlessly with the inner wall of the through hole.

[0007] Preferably, a connecting post is fixed to the bottom of the abutment block, and an installation hole is provided on the top of the foam block. The connecting post is engaged with the installation hole, which can achieve a snap-fit ​​connection and is easy to operate. The diameter of the connecting post is larger than the inner diameter of the installation hole.

[0008] Preferably, the rotating column has a horizontal part and a vertical part, the abutment abuts against the bottom end face of the horizontal part of the rotating column, which facilitates subsequent fastening, and the hook is set on one side of the bottom end of the vertical part of the rotating column, and the cross-section of the limiting hole is "L" shaped.

[0009] Preferably, the housing includes a housing and a top cover connected by hinges. The detection host is placed inside the housing. A buffer block is also embedded in the gap between the housing and the detection host for buffering and shock absorption, providing protection for the detection host. The buffer block has an annular groove inside. An airbag is placed inside the annular groove. A connecting tube extending to the outside of the buffer block is provided on the top of the airbag. A pressure sensor is also embedded in the inner wall of the annular groove.

[0010] Preferably, a connecting piece is connected to the top of the connecting tube to connect the sealing plug, and a sealing plug for sealing the port of the connecting tube is provided on the inner side of the connecting piece.

[0011] This invention also discloses a method for a life search and rescue device under conditions of intelligent landslide burial, the specific steps of which are as follows:

[0012] Step 1: Place the pressure sensor inside the inner wall of the ring groove, with the detection end of the pressure sensor facing the inner wall of the buffer block. Then insert the airbag into the inner side of the ring groove, and make the connecting tube on the airbag pass through to the top of the buffer block.

[0013] Step Two: When conducting search and rescue operations for lives buried by a landslide, first open the battery cover, then place the battery in the battery compartment of the detection host. Next, connect the battery cover to the detection host. During connection, press down the rotating pins at both ends of the battery cover until the bottom of the rotating pin contacts the bottom of the limiting hole. Then rotate the rotating pin, causing the hook to abut against the inner wall of the limiting hole. When pressing the rotating pin, the bottom horizontal surface of the rotating pin will press against the abutment block, which in turn will press against the foam block, causing the foam block to move towards the bottom of the through hole. The water source placed inside the through hole will move to the inside of the receiving cavity, allowing the foam block to descend. During the descent of the foam block, the sealing ring prevents the liquid inside the through hole from leaking out through the gap. At the same time, when the liquid moves to the inside of the receiving cavity, the buoyancy provided by the liquid to the abutment increases, and the abutment is lifted. The abutment will lift the rotating column, so that the hook at the bottom of the rotating column can be tightly fitted with the limiting hole, thus achieving installation. During disassembly, the rotating column is rotated in the opposite direction, and under the action of buoyancy, the hook is popped out from inside the limiting hole.

[0014] Step 3: Open the sealing plug, connect the external air supply device to the connecting pipe, and inflate the airbag to expand the annular groove. This will allow the pressure sensor on the inner wall of the buffer block to fit tightly against the detection host. The pressure sensor will detect the pressure until the specified value is reached. This indicates that the installation limit of the detection host is complete, preventing the vibration of the detection host caused by errors from affecting the shock absorption effect of the buffer block.

[0015] Step 4: During the measurement, align the detection host with the rear surface of the casing towards the area to be measured, use radar to detect the signal of the buried life form, and transmit the signal to the handheld tablet.

[0016] Preferably, in step four, the display range of the area to be tested is fan-shaped, and the information displayed on the handheld tablet includes charts, wavy lines, and numerical values.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The designed connecting component replaces the existing method of installation by hand-tightening bolts, making it very convenient to install and remove the battery cover, thus improving work efficiency. In addition, the connection loss of this connecting component is small, and it will not suffer from the fatigue of existing bolts and springs. The overall service life is longer and the manufacturing cost is lower. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 5This invention provides a technical solution: an intelligent life search and rescue device under landslide burial conditions, comprising a shell and a detection component disposed inside the shell. The detection component consists of a handheld tablet 1 and a detection host 8 wirelessly connected. The shell serves as a protective layer. The detection host 8 has a battery compartment, and a battery 3, which is detachably inserted into the battery compartment, is placed inside the shell. A battery cover 5 is also provided on the top of the battery compartment for closing the battery 3. Connecting components for connecting to the detection host 8 are provided at both ends of the battery cover 5. The design of the connecting components replaces the existing method of installation by hand-tightening bolts, and the battery cover 5 is also very convenient to install and remove. This improves work efficiency, while also reducing connection loss and avoiding fatigue associated with existing bolts and springs. It boasts a longer overall service life and lower manufacturing costs. The connection component comprises a limiting component and a buffer component. The limiting component includes a rotating column 10 penetrating the battery cover 5, with a hook 11 formed on one side of the bottom end of the rotating column 10. A limiting hole 23 for the hook 11 to engage is provided on the top of the detection host 8. A through hole 15 is also provided on the top of the battery cover 5. Liquid is injected into the through hole 15, and the buffer component floats on the liquid inside the through hole 15, with the top of the limiting component in contact with the rotating column 10.

[0027] In this embodiment, preferably, the buffer assembly includes a stop block 9 and a foam block 12 arranged from top to bottom. The stop block 9 is made of rigid plastic, which is lightweight and can also ensure that it will not deform significantly under pressure. The bottom end of the foam block 12 has multiple receiving cavities 16. At least one sealing ring 13 is sleeved on the outer side of the foam block 12. The outer diameter of the sealing ring 13 fits seamlessly with the inner wall of the through hole 15. A connecting post 17 is fixed at the bottom of the stop block 9. An installation hole 18 is provided at the top of the foam block 12. The connecting post 17 is engaged with the installation hole 18 for easy installation. The diameter of the connecting post 17 is larger than the inner diameter of the installation hole 18. The rotating post 10 has a horizontal part and a vertical part. The stop block 9 abuts against the bottom end face of the horizontal part of the rotating post 10 to achieve a limiting engagement. The hook 11 is provided on one side of the bottom end of the vertical part of the rotating post 10. The cross-section of the limiting hook hole 23 is "L" shaped.

[0028] In this embodiment, the outer casing includes an outer casing 6 and a top cover 2 connected by hinges. The detection host 8 is placed inside the outer casing 6. A buffer block 4 is also embedded in the gap between the outer casing 6 and the detection host 8 to achieve buffering and prevent damage to the detection host 8 caused by vibration. An annular groove 21 is opened inside the buffer block 4. An airbag 19 is also placed inside the annular groove 21. A connecting tube 7 extending to the outside of the buffer block 4 is provided on the top of the airbag 19. A pressure sensor 20 is also embedded in the inner wall of the annular groove 21 to detect the magnitude of the pressure. A connecting piece 14 is connected to the top of the connecting tube 7. A sealing plug 22 for sealing the port of the connecting tube 7 is provided inside the connecting piece 14.

[0029] This invention also discloses a method for a life search and rescue device under conditions of intelligent landslide burial, the specific steps of which are as follows:

[0030] Step 1: Place the pressure sensor 20 inside the inner wall of the annular groove 21, with the detection end of the pressure sensor 20 facing the inner wall of the buffer block 4. Then insert the airbag 19 into the inner side of the annular groove 21, and make the connecting tube 7 on the airbag 19 extend to the top of the buffer block 4.

[0031] Step Two: When conducting search and rescue operations for lives buried by a landslide, first open the battery cover 5, then place the battery 3 into the battery compartment inside the detection host 8. Next, connect the battery cover 5 to the detection host 8. During connection, press down the rotating columns 10 at both ends of the battery cover 5 until the bottom end of the rotating column 10 contacts the bottom end of the limiting hole 23. Then rotate the rotating column 10 so that the hook 11 abuts against the inner wall of the limiting hole 23. When pressing the rotating column 10, the bottom horizontal surface of the rotating column 10 will press against the abutment block 9, which in turn will press against the foam block 12. The foam block 12 moves towards the bottom of the through hole 15. The water source placed inside the through hole 15 will move to the inside of the receiving cavity 16, thereby allowing the foam block 12 to descend. During the descent of the foam block 12, the sealing ring 13 prevents the liquid inside the through hole 15 from being discharged from the gap. At the same time, when the liquid moves to the inside of the receiving cavity 16, the buoyancy provided by the liquid to the abutment 9 increases, and the abutment 9 is lifted. The abutment 9 will lift the rotating column 10, so that the hook 11 at the bottom of the rotating column 10 is tightly fitted with the limiting hole 23, thereby realizing the installation. During the later disassembly, the rotating column 10 is directly rotated in the opposite direction, and under the action of buoyancy, the hook 11 is popped out from the inside of the limiting hole 23.

[0032] Step 3: Open the sealing plug 22, connect the external air supply device to the connecting pipe 7, and inflate the airbag 19 so that the airbag 19 expands the annular groove 21, so that the pressure sensor 20 on the inner wall of the buffer block 4 is tightly attached to the detection host 8, and the pressure is detected by the pressure sensor 20 until the specified value is reached, which indicates that the installation limit of the detection host 8 is completed, so as to avoid the vibration of the detection host 8 caused by error from affecting the shock absorption and buffering effect of the buffer block 4.

[0033] Step 4: During the measurement, the detection host 8 is aligned with the rear surface of the outer casing 6 to be measured, and the signal of the buried life form is detected by radar and transmitted to the handheld tablet 1.

[0034] In this embodiment, in step four, the display range of the area to be tested is fan-shaped, and the information displayed on the handheld tablet 1 includes charts, wavy lines, and numerical values.

[0035] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
