Description

Technical Field

[0001] The present invention relates to the technical field of radar detection equipment, and in particular to a portable radar life detector. Background Art

[0002] Radar life detectors are high-tech rescue equipment developed based on radar technology. They emit electromagnetic waves and receive echo signals reflected by living organisms such as the human body. After signal processing, they determine whether there are signs of life. They are mainly used in disaster rescue sites such as earthquakes, fires, and building collapses to help rescue personnel quickly determine the location of trapped people and improve rescue efficiency and success rate.

[0003] After searching, the invention patent with publication number CN116817090A discloses a life detection radar device, including a base, a pulley assembly, a driving mechanism, a detection radar body, a pushing assembly, a pressing assembly and a stop assembly; a groove is provided on the top surface of the base, and a plurality of pulley assemblies are provided and evenly distributed on the bottom surface of the base; the driving mechanism is rotatably provided on the base, and the detection radar body is provided on the driving mechanism; the pushing assembly and the pressing assembly are respectively slidably provided in the groove of the base, and the rotation of the driving mechanism can drive the pushing assembly to slide toward the pressing assembly, and make the pressing assembly slide toward the stop assembly; a plurality of elongated holes are provided on the bottom surface of the base assembly, and the stop assembly can be slidably provided in the groove of the base and can slide in the elongated holes, and the sliding of the pressing assembly can simultaneously make a plurality of stop assemblies slide toward the pulley assembly, and insert into the pulley assembly to limit the rotation of the pulley assembly. The above-mentioned life detection radar device does not need to continuously limit the base when rotating.

[0004] In conjunction with the aforementioned patents, the following deficiencies were discovered in the prior art: Existing radar life detectors generally only detect vertically downward. This single detection direction greatly limits their application in complex rescue environments. (For example, after a building collapses, trapped people may be in various inclined, horizontal, or other non-vertical spatial positions, and existing detectors are unable to effectively detect signs of life in these positions.) Furthermore, the detection range of existing radar life detectors is not adjustable and is relatively small. At large disaster sites, rescuers need to frequently move the detector to cover different areas, which not only wastes time but may also cause trapped people to be missed due to detection blind spots. Furthermore, the small detection range makes it difficult to quickly detect signs of life at long distances or in large spaces, reducing rescue efficiency and hindering the timely saving of lives. Therefore, there is an urgent need to propose a portable radar life detector to improve the above-mentioned problems. Summary of the Invention

[0005] In view of the above-mentioned existing technologies, the technical problem to be solved by the present invention is that the detection range of the existing radar life detector cannot be adjusted and the detection range is small.

[0022] 1. The present invention uses a motor in the rotating mechanism to drive the worm box and the first gear to rotate, which engages with the tooth groove at the bottom of the outer wall of the turntable, thereby realizing 360° horizontal rotation of the turntable. At the same time, the worktable surface is designed to be spherical and cooperates with the spherical groove of the turntable through a clamping assembly.

[0025] 4. The present invention can block the entry of debris by setting a protective mesh plate inside the chassis to avoid affecting the operation of the equipment. When the rotating mechanism is working, the cleaning component runs synchronously to automatically clean the protective mesh plate without additional operation, thereby reducing the labor cost of equipment maintenance and ensuring that the equipment is in good condition during long-term operation.

The push-pull rod 29 and the snap-on assembly are designed on the same plane. One end of the push-pull rod 29 is rotatably connected to a connecting column 30, and a pulley 31 is installed at the bottom of the connecting column 30. The pulley 31 and the connecting column 30 are both slidably set in the steering groove 3 2, the starting motor 212 drives the worm box to work, drives the first gear 211 to rotate, and cooperates with the meshing action of the first gear 211 and the tooth groove 213 to drive the rotating table 6 to rotate 360 ​​degrees horizontally on the circumferential inner wall of the support platform 5. At the same time, the push-pull rod 29 is pushed, and the push-pull rod 29 drives the connecting column 30 and the pulley 31 to slide in the steering groove 32 of the steering frame 17. Since the surface of the workbench 7 and the spherical groove 26 of the rotating table 6 are adapted through the clamping assembly, and the hinge seat 28 on one side of the surface of the workbench 7 is rotatably connected to the push-pull rod 29, the workbench 7 is converted from a vertical shape to an inclined shape, thereby realizing flexible adjustment of the detection direction of the detection radar body 9 to meet the detection needs of different rescue scenarios and improve the detection range.

[0050] In the present invention, the handle assembly 4 includes a first connecting groove 41 and a second connecting groove 48 respectively provided on both sides of the top of the machine cover 3, and the inner wall of the first connecting groove 41 is rotatably connected to the first L-shaped rod 42, one end of the first L-shaped rod 42 is fixed with a handle rod 43, one end of the handle rod 43 is provided with a slot 45, and the cross-section of the slot 45 is designed to be T-shaped, the inner wall of the slot 45 is plugged with a limiting seat 44, one end of the limiting seat 44 is fixed with a telescopic rod 46 extending out of the slot 45, one end of the telescopic rod 46 is fixed with a second L-shaped rod 47, and the bottom end of the second L-shaped rod 47 is fixed with a handle frame 49 located in the second connecting groove 48, and a restraining assembly for restraining the handle frame 49 is provided on the second connecting groove 48, and the restraining assembly includes a movable groove 412 provided at the bottom of the second connecting groove 48, and one end of the movable groove 412 and one end of the machine cover 3 are provided with a jack, and the inner wall of the movable groove 412 is movably provided with an L-shaped movable seat 414 The movable base 414 is fixed with a movable rod 411 passing through the insertion hole at one end, and a toggle rod 410 is fixed to one end of the movable rod 411, and a first spring 413 is fixedly installed on the inner wall of the movable groove 412 on one side of the movable base 414 and the outer wall of the movable rod 411. A plurality of positioning holes 416 are opened on one side of the handle frame 49, and a plurality of positioning rods 415 are fixed on the other side of the movable base 414 and inserted into the positioning holes 416. When carrying the device, you can directly hold the handle rod 43, or you can adjust the position of the toggle rod 410 in the binding assembly to make the positioning rod 415 disengage from the positioning hole 416. At this time, the handle frame 49, the second L-shaped rod 47, the telescopic rod 46, the handle rod 43 and the first L-shaped rod 42 are changed from horizontal to vertical, and the telescopic rod 46 is gradually pulled out of the slot 45.

The surface of the annular shielding layer 14 is spherical, and the annular shielding layer 14 is made of a honeycomb hollow high-strength carbon fiber composite material. The annular shielding layer 14 shields external electromagnetic interference, further protecting the normal operation of the detection radar body 9.

[0053] Second implementation method:

[0054] This embodiment is based on the first embodiment, and the following structure is added to enable this application to have the functions of protection and self-cleaning. The specific settings are as follows: Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, a support plate 16 is fixedly installed on the bottom of the inner wall of the chassis 1, and a disc-shaped protective screen 18 is fixedly installed in the middle of the support plate 16. A cleaning component 20 is provided at the bottom of the protective screen 18. The cleaning component 20 includes a connecting shaft 205 fixedly installed at the bottom of the worm box output shaft, and a through hole for the connecting shaft 205 to pass through is provided on the support plate 16. A second gear 204 is fixedly installed at the bottom of the connecting shaft 205. An annular groove is provided at the bottom of the support plate 16, and an annular slide 202 is slidably provided on the inner wall of the annular groove. The cross-sections of the annular slide 202 and the annular slide are both convex. The bottom of the annular slide 202 is fixedly installed with a gear meshing with the second gear 204. The gear ring 203 is engaged, and a scraper 201 is fixedly installed on the inner wall of the gear ring 203. The scraper 201 is attached to the bottom of the protective mesh plate 18. The protective mesh plate 18 is provided to prevent debris from entering to avoid affecting the operation of the equipment. When the motor 212 drives the worm box to work, the connecting shaft 205 at the bottom of the worm box output shaft also rotates accordingly, and cooperates with the meshing action of the second gear 204 and the gear ring 203, so that the gear ring 203 drives the annular slide 202 to slide in the annular groove, so that the scraper 201 moves in contact with the bottom of the protective mesh plate 18, automatically removing dust, debris and other debris on the protective mesh plate 18, ensuring a clean environment inside the equipment and reducing the probability of equipment failure.

[0055] To summarize, the working principle of the present invention is as follows: when carrying the device, the user can directly hold the handle bar 43, or adjust the position of the toggle rod 410 in the restraint assembly to disengage the positioning rod 415 from the positioning hole 416. At this time, the handle frame 49, the second L-shaped rod 47, the telescopic rod 46, the handle bar 43 and the first L-shaped rod 42 are changed from horizontal to vertical, and the telescopic rod 46 is gradually pulled out of the slot 45. In conjunction with the arrangement of the moving wheels 8, the entire detector can be conveniently pulled for movement.

[0056] After turning on the equipment, life detection is performed directly through the detection radar body 9 and the bell mouth 19. If the detection direction needs to be adjusted, the motor 212 on the motor frame is started to drive the worm box to work. The first gear 211 on the top of the worm box output shaft rotates and engages with the tooth groove 213 at the bottom of the outer wall of the rotary table 6, driving the rotary table 6 to rotate 360° horizontally on the circumferential inner wall of the support table 5 through the bearing. At the same time, the push-pull rod 29 is pushed, and the push-pull rod 29 drives the connecting column 30 and the pulley 31 to slide in the adjustment groove 32 of the adjustment frame 17. Since the surface of the workbench 7 is adapted to the spherical groove 26 of the rotary table 6 through the clamping assembly, and the hinged seat 28 on one side of the surface of the workbench 7 is rotatably connected to the push-pull rod 29, the workbench 7 is changed from a vertical state to a vertical state. Converted into an inclined shape, the detection direction of the detection radar body 9 is flexibly adjusted to meet the detection needs of different rescue scenarios. During detection, the detection radar body 9 emits electromagnetic waves, which propagate outward through the horn 19. When encountering a living body such as a human body, the living body reflects an echo signal, and the echo signal returns to the detection radar body 9 through the horn 19. The detection radar body 9 transmits the received signal to the controller 11 integrated in the cover 3. After processing the signal, the controller 11 displays the life sign information on the display 12. Rescuers judge whether there is a life sign and the location of the life sign based on this. The annular shielding layer 14 inside the workbench 7 is used to shield external electromagnetic interference to protect the normal operation of the detection radar body 9;

[0057] Moreover, when the motor 212 drives the worm gear box to work, the connecting shaft 205 at the bottom of the worm gear box output shaft also rotates accordingly, and the second gear 204 at the bottom of the connecting shaft 205 engages with the ring gear 203, and the ring gear 203 drives the annular slide 202 to slide in the annular groove at the bottom of the support plate 16. The scraper 201 on the inner wall of the ring gear 203 moves along the bottom of the protective mesh plate 18, automatically removing dust, debris and other debris on the protective mesh plate 18.

[0058] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
