Description

Technical Field

[0001] This invention belongs to the technical field of life detection equipment, specifically an indoor automatic life detection device. Background Technology

[0002] An independent individual with a life form is a living organism, capable of responding to external stimuli. In the fields of life safety and theft prevention, infrared thermal sensors and microwave sensors are typically used to detect living organisms, enabling timely detection and achieving life safety protection and advanced theft prevention.

[0003] Existing indoor life detection devices use rotatable infrared thermal sensors and microwave sensors for rotational scanning to scan the indoor space and detect the presence of life in a timely manner. However, the actual structure of the detection device itself is quite complex. During installation and deployment, it is necessary to disassemble the protective mechanism on the outside of the infrared thermal sensor and microwave sensor, store them separately after disassembly, and then install them at a certain height. The actual installation and deployment requires many disassembly and assembly steps, and the separate structure presents problems with shelving and storage. In fact, it needs to be reassembled before transportation, making the operation cumbersome and the use effect unsatisfactory.

[0004] Furthermore, with the passage of time, existing indoor automatic identification detection devices accumulate a layer of dust on the outer surface of infrared thermal sensors and microwave sensors. When the environment has a certain humidity, the dust mixes with moisture to form surface dirt. As the dirt thickness increases, the penetration of the detection waves of the infrared thermal sensors and microwave sensors gradually decreases, thereby reducing the indoor identification and detection depth, shrinking the actual detection area, and resulting in poor performance. Summary of the Invention

[0005] The purpose of this invention is to provide an indoor detection device for automatic identification of living organisms, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an indoor automatic identification detection device for living organisms, comprising a first plate and a second plate, a central shaft fixedly connected between the first plate and the second plate, a sleeve movably fitted onto the outer surface of the central shaft, a connecting plate fixedly connected to the outer surface of the sleeve, a detection mechanism fixedly installed on the outer end face of the connecting plate, a first arc plate and a second arc plate movably fitted onto the bottom surface of the first plate, an arc groove formed on the bottom surface of the first plate, the inner surface of the arc groove movably fitted onto the first arc plate and the second arc plate, a bottom plate fixedly connected to the bottom surface of the first arc plate and the second arc plate, a mounting frame fixedly installed on the bottom surface of the first plate, a motor and an air pump respectively provided on the inner side of the mounting frame, positioning frames fixedly connected to the outer surfaces of both the first arc plate and the second arc plate, a fixing rod fixedly connected to the outer surface of the first plate, a locking cap threaded onto the outer surface of the fixing rod, and a magnetic block fixedly connected to the bottom surface of the second plate.

[0007] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the device needs to be installed, pull the bottom plate, which will cause the bottom plate to move the first and second arc plates. This will cause the first and second arc plates to move downwards along the arc groove of the first plate. At the same time, the top surfaces of the first and second arc plates will separate from the magnetic block. As the first and second arc plates, which surround the outside of the detection mechanism, move downwards, the detection mechanism will be exposed and opened. When pulled to the bottom, the side groove on the side of the positioning frame will be movably engaged with the fixing rod. Tighten the locking cap.

[0008] First, an arc groove is opened on the bottom surface of the first plate, and the first and second arc plates are nested in the groove. The first and second arc plates are distributed in a ring with equal spacing. When disassembling and assembling, the first and second arc plates surround the outside of the detection mechanism, thus protecting the detection mechanism. When installation is required, the first and second arc plates are pulled down and, after being pulled out, they cooperate with the bottom plate on the bottom surface of the first and second arc plates, so that the device can be stably placed on a horizontal surface. After opening, the detection mechanism has a certain height, which improves the detection effect. At the same time, no disassembly of some components is required during the entire installation process. The detection device has a strong overall structure and is easy to use.

[0009] Preferably, the output shaft of the motor is fixedly connected to a rotating shaft, a first gear is fixedly sleeved on the outer surface of the rotating shaft, a second gear is fixedly sleeved on the outer surface of the sleeve, the first gear and the second gear are meshed and connected, and a cover plate is fixedly connected to the top surface of the first plate. The cover plate is located outside the first gear and the second gear. By using the motor to drive the first gear to rotate, and cooperating with the second gear to realize the rotation of the sleeve, the rotation scanning of the detection mechanism is realized.

[0010] Preferably, there are two of each of the first and second arc plates, and the two first and two second arc plates are distributed alternately to ensure that after the upward reset, the first and second arc plates effectively protect the detection mechanism and surround the outside of the detection mechanism.

[0011] Preferably, a sleeve hole is provided inside the first arc plate, and a sleeve rod is movably sleeved on the inner surface of the sleeve hole. A mounting base is fixedly connected to the upper end of the sleeve rod, and a cleaning pad is fixedly installed on the top surface of the mounting base. By using the upward movement of the cleaning pad, the surface of the detection mechanism that moves to one side of the first arc plate is cleaned, thereby improving the penetration effect of the emitted wave.

[0012] Preferably, the top surface of the bottom plate has a first hole and a second hole, and the inside of the bottom plate has an arc-shaped cavity that is connected to the first hole and the second hole. The arc-shaped cavity is used to guide the air supply, and the air supply is distributed to the upper and lower sides in conjunction with the first hole.

[0013] Preferably, a spring is fixedly connected to the bottom surface of the arc-shaped cavity, a push plate is fixedly connected to the upper end of the spring, and a sealing rod is fixedly connected to the top surface of the push plate. The outer surface of the sealing rod is movably sleeved with the second hole. By utilizing the sleeved connection between the sealing rod and the second hole, and in conjunction with the elasticity of the spring, when the device is opened for use, the air pressure is insufficient to push open the sealing rod and push the sleeve rod upward. After the first and second arc plates are reset, the sleeve rod lacks sufficient space to move. Sufficient gas can push open the sealing rod and compress the spring, thereby enabling air to be supplied. The spring can be reset when the air supply is disconnected.

[0014] Preferably, the second arc plate has a mounting groove on its side, and an elastic airbag is fixedly connected to the inner surface of the mounting groove. The bottom surface of the second arc plate has a third hole, and the two ends of the third hole are respectively connected to the elastic airbag and the first hole. By using the third hole to introduce the air introduced into the first hole into the elastic airbag, the elastic airbag is inflated and expanded, thereby protecting the inner detection mechanism.

[0015] Preferably, a retaining ring is fixedly sleeved on the outer surface of the intermediate shaft, and an annular groove is formed on the inner surface of the sleeve. The inner surface of the annular groove is movably sleeved with the retaining ring. By utilizing the movable sleeved connection between the retaining ring and the annular groove, the sleeve can rotate stably around the intermediate shaft, avoiding vertical displacement.

[0016] Preferably, the outer surface of the positioning frame is provided with a side groove, the width of which is greater than the diameter of the fixing rod, to ensure that the side groove of the positioning frame is sleeved with the fixing rod and is clamped and fixed in conjunction with the locking cap.

[0017] Second embodiment: as follows Figure 1 , Figure 2 , Figure 4, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when cleaning is required, the air pump is started, allowing air to be introduced into the sleeve hole of the first arc plate through the curved pipe. As air is introduced into the sleeve hole, the air pushes the sleeve rod upward, which in turn moves the mounting base upward, causing the cleaning pad on the side of the mounting base to move upward and scraping away dust from the surface of the stationary detection mechanism during the upward movement. When safe transportation is required, the detection mechanism is kept on one side of the second arc plate, and the first and second arc plates are pushed back to their original positions and fixed with the magnetic block. The air pump is started, and as air is introduced into the sleeve hole through the curved pipe, the sleeve rod in the sleeve hole loses its space to move after resetting. The continuously introduced air pushes the sealing rod downward, and at the same time, the spring is compressed, allowing the air entering the arc cavity to enter the elastic airbag through the first and third holes, causing the elastic airbag to expand and press against the detection mechanism.

[0018] First, by adding an air pump and a curved pipe to circulate air into the No. 1 arc plate, the air entering the No. 1 arc plate pushes the internal sleeve rod upward. This upward movement of the sleeve rod, when the detection mechanism is located on one side of the No. 1 arc plate, causes the mounting base to move upward, thereby moving the cleaning pad on top of the mounting base along the detection mechanism and scraping away dirt and dust from the surface of the detection mechanism. This improves the cleanliness of the detection mechanism surface, ensures the penetration effect of the emitted waves from the external heat sensor and microwave sensor, and guarantees a stable detection space range.

[0019] Furthermore, by creating an arc-shaped cavity inside the bottom plate and adding a spring inside the arc-shaped cavity, a push plate is connected using the spring, and the sealing rod on the top surface of the push plate seals the No. 2 hole. After the No. 1 and No. 2 arc plates move up and reset, the continuously introduced air pushes open the sealing rod and enters the arc-shaped cavity. The air in the arc-shaped cavity then enters the elastic airbag through the No. 1 and No. 3 holes. This allows the detection mechanism, which is adjusted to the side of the No. 2 arc plate, to be clamped and protected by the inflated elastic airbag. When the outside is impacted, the detection mechanism is effectively buffered and protected, greatly improving the safety during transportation and movement, and demonstrating good performance.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention creates an arc groove on the bottom surface of a first plate, into which a first arc plate and a second arc plate are fitted. The first and second arc plates are arranged in a ring with equal spacing. During assembly and disassembly, the first and second arc plates surround the outer side of the detection mechanism, protecting it. When installation is required, the first and second arc plates can be pulled out downwards. After being pulled out, they cooperate with the bottom plate on the bottom surface of the first and second arc plates, allowing the device to be stably placed on a horizontal surface. When opened, the detection mechanism has a certain height, improving the detection effect. At the same time, the entire installation process does not require the disassembly of some components, resulting in a strong overall structure and convenient use of the detection device.

[0022] 2. This invention utilizes an additional air pump and curved pipe to circulate air into the first arc plate, thereby causing the air entering the first arc plate to push the internal sleeve rod upward. This upward movement of the sleeve rod, when the detection mechanism is located on one side of the first arc plate, causes the mounting base to move upward, thereby causing the cleaning pad on top of the mounting base to move upward along the detection mechanism. This removes dirt and dust from the surface of the detection mechanism, improving its cleanliness and ensuring the penetration effect of the emitted waves from the external heat sensor and microwave sensor, thus guaranteeing a stable detection space range.

[0023] 3. This invention creates an arc-shaped cavity inside the bottom plate and adds a spring inside the arc-shaped cavity. The spring connects to a push plate, and a sealing rod on the top surface of the push plate seals the second hole. After the first and second arc plates move up and reset, the continuously flowing air pushes open the sealing rod and enters the arc-shaped cavity. The air in the arc-shaped cavity then enters the elastic airbag through the first and third holes. This allows the detection mechanism, which is adjusted to the side of the second arc plate, to be clamped and protected by the inflated elastic airbag. When the outside is impacted, this effectively buffers and protects the detection mechanism, greatly improving safety during transportation and movement, and demonstrating good performance.

[0033] 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 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.

[0034] like Figures 1 to 8As shown, this embodiment of the invention provides an indoor automatic identification detection device for living beings, including a first plate 1 and a second plate 2. An intermediate shaft 3 is fixedly connected between the first plate 1 and the second plate 2. A sleeve 4 is movably sleeved on the outer surface of the intermediate shaft 3. A connecting plate 5 is fixedly connected to the outer surface of the sleeve 4. A detection mechanism 6 is fixedly installed on the outer end face of the connecting plate 5. The detection mechanism 6 specifically includes an infrared thermal sensor YRH300 and a microwave sensor mVn8DoK4. A first arc plate 14 and a second arc plate 15 are movably sleeved on the bottom surface of the first plate 1. An arc groove 13 is provided, and the inner surface of the arc groove 13 is movably connected to the first arc plate 14 and the second arc plate 15. The bottom surfaces of the first arc plate 14 and the second arc plate 15 are fixedly connected to a bottom plate 16. The bottom surface of the first plate 1 is fixedly installed with a mounting bracket 7. The inner side of the mounting bracket 7 is respectively provided with a motor 8 and an air pump 20. The outer surfaces of the first arc plate 14 and the second arc plate 15 are both fixedly connected with positioning brackets 17. The outer surface of the first plate 1 is fixedly connected with a fixing rod 18. The outer surface of the fixing rod 18 is threaded with a locking cap 19. The bottom surface of the second plate 2 is fixedly connected with a magnetic block 21.

[0035] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the device needs to be arranged, pull the bottom plate 16, so that the bottom plate 16 drives the first arc plate 14 and the second arc plate 15 to move, so that the first arc plate 14 and the second arc plate 15 move downward along the arc groove 13 of the first plate 1. At the same time, the top surface of the first arc plate 14 and the second arc plate 15 separates from the magnetic block 21. As the first arc plate 14 and the second arc plate 15 surrounding the outside of the detection mechanism 6 move downward, the detection mechanism 6 is exposed and opened. When pulled to the bottom, the side groove 38 on the side of the positioning frame 17 is movably connected with the fixing rod 18. Tighten the locking cap 19.

[0036] First, an arc groove 13 is opened on the bottom surface of plate 1, and arc plates 14 and 15 are fitted into the arc groove 13. The arc plates 14 and 15 are distributed in a ring with equal spacing. When disassembling and assembling, the arc plates 14 and 15 surround the outside of the detection mechanism 6, thus protecting the detection mechanism 6. When installation is required, arc plates 14 and 15 are pulled down and, after being pulled out, they cooperate with the bottom plate 16 on the bottom surface of arc plates 14 and 15, so that the device can be stably placed on a horizontal surface. After opening, the detection mechanism 6 has a certain height, which improves the detection effect. At the same time, no disassembly of some components is required during the entire installation process. The detection device has a strong overall structure and is easy to use.

[0037] Among them, the output shaft of the motor 8 is fixedly connected to the rotating shaft 9, the outer surface of the rotating shaft 9 is fixedly sleeved with a first gear 10, the outer surface of the sleeve 4 is fixedly sleeved with a second gear 11, the first gear 10 and the second gear 11 are meshed and connected, the top surface of the first plate 1 is fixedly connected with a cover plate 12, the cover plate 12 is located outside the first gear 10 and the second gear 11. By using the motor 8 to drive the first gear 10 to rotate, and cooperating with the second gear 11 to realize the rotation of the sleeve 4, the detection mechanism 6 can perform rotation scanning.

[0038] There are two of each of the first arc plate 14 and the second arc plate 15. The two first arc plates 14 and the two second arc plates 15 are distributed alternately to ensure that after the upward reset, the first arc plate 14 and the second arc plate 15 effectively protect the detection mechanism 6 and surround the outside of the detection mechanism 6.

[0039] One of the arc plates 14 has a sleeve hole 22 inside. A sleeve rod 23 is movably sleeved on the inner surface of the sleeve hole 22. A mounting base 24 is fixedly connected to the upper end of the sleeve rod 23. A cleaning pad 25 is fixedly installed on the top surface of the mounting base 24. The surface of the detection mechanism 6, which moves to one side of the arc plate 14, is cleaned by moving the cleaning pad 25 upward, thereby improving the penetration effect of the emitted wave.

[0040] The bottom plate 16 has a first hole 28 and a second hole 29 on its top surface. The bottom plate 16 has an arc-shaped cavity 27 inside, which is connected to the first hole 28 and the second hole 29. The arc-shaped cavity 27 is used to guide the air supply, and the first hole 28 is used to distribute the air supply to the upper sides.

[0041] The bottom surface of the arc cavity 27 is fixedly connected to a spring 30, the upper end of the spring 30 is fixedly connected to a push plate 31, and the top surface of the push plate 31 is fixedly connected to a sealing rod 32. The outer surface of the sealing rod 32 is movably sleeved with the second hole 29. By using the sealing rod 32 to sleeve the second hole 29 and in conjunction with the elasticity of the spring 30, when it is opened for use, the air pressure is insufficient to push open the sealing rod 32 and push the sleeve rod 23 upward. After the first arc plate 14 and the second arc plate 15 are reset, the sleeve rod 23 lacks sufficient space to move. Sufficient gas can push open the sealing rod 32 and compress the spring 30 to achieve air supply. The spring 30 can be reset when the air supply is disconnected.

[0042] Among them, the side of the second arc plate 15 is provided with a mounting groove 33, and the inner surface of the mounting groove 33 is fixedly connected to an elastic airbag 35. The bottom surface of the second arc plate 15 is provided with a third hole 34, and the two ends of the third hole 34 are respectively connected to the elastic airbag 35 and the first hole 28. By using the third hole 34 to introduce the air introduced into the first hole 28 into the elastic airbag 35, the elastic airbag 35 is inflated and expanded, thereby protecting the inner detection mechanism 6.

[0043] The outer surface of the intermediate shaft 3 is fixedly fitted with a retaining ring 37, and the inner surface of the sleeve 4 is provided with an annular groove 36. The inner surface of the annular groove 36 is movably fitted with the retaining ring 37. By utilizing the movable fit between the retaining ring 37 and the annular groove 36, the sleeve 4 can rotate stably around the intermediate shaft 3, avoiding vertical displacement.

[0044] The outer surface of the positioning frame 17 is provided with a side groove 38. The width of the side groove 38 is greater than the diameter of the fixing rod 18, so as to ensure that the side groove 38 of the positioning frame 17 is sleeved with the fixing rod 18 and is clamped and fixed in conjunction with the locking cap 19.

[0045] Second embodiment: as follows Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when cleaning is required, the air pump 20 is activated, allowing air to be introduced into the sleeve hole 22 of the first arc plate 14 through the curved pipe 26. As air is introduced into the sleeve hole 22, the air pushes the sleeve rod 23 upward, thereby causing the sleeve rod 23 to move the mounting base 24 upward, causing the cleaning pad 25 on the side of the mounting base 24 to move upward, and scraping off the dust from the surface of the stationary detection mechanism 6 during the upward movement. When safe transportation is required, the detection mechanism 6 is kept on one side of the second arc plate 15. The first arc plate 14 and the second arc plate 15 are pushed up and reset, and are attracted and fixed to the magnetic block 21. The air pump 20 is started. As the air pump 20 circulates air into the sleeve hole 22 through the curved pipe 26, the sleeve rod 23 in the sleeve hole 22 is reset and loses its movement space. The continuously filled air pushes the sealing rod 32 down, and at the same time the spring 30 is compressed, so that the air entering the arc cavity 27 enters the elastic airbag 35 through the first hole 28 and the third hole 34, causing the elastic airbag 35 to expand and press against the detection mechanism 6.

[0046] First, by using an additional air pump 20 and curved pipe 26 to circulate air into the first arc plate 14, the air entering the first arc plate 14 pushes the internal sleeve rod 23 upward, thereby pushing the sleeve rod 23 upward. When the detection mechanism 6 is located on one side of the first arc plate 14, the upward-moving sleeve rod 23 drives the mounting base 24 to move upward, thereby causing the cleaning pad 25 on the top of the mounting base 24 to move upward along the detection mechanism 6, and scraping off dirt and dust on the surface of the detection mechanism 6, improving the cleanliness of the surface of the detection mechanism 6, ensuring the penetration effect of the emitted waves of the external heat sensor and microwave sensor, and ensuring a stable detection space range.

[0047] Furthermore, by opening an arc-shaped cavity 27 inside the bottom plate 16 and adding a spring 30 inside the arc-shaped cavity 27, the spring 30 is connected to the push plate 31, and the sealing rod 32 on the top surface of the push plate 31 seals the second hole 29. After the first arc plate 14 and the second arc plate 15 move upward and reset, the continuously introduced air pushes open the sealing rod 32 and enters the arc-shaped cavity 27. The air in the arc-shaped cavity 27 enters the elastic airbag 35 through the first hole 28 and the third hole 34, so that the detection mechanism 6 adjusted to the side of the second arc plate 15 is clamped and protected by the expanded elastic airbag 35. When the outside is hit, the detection mechanism 6 is effectively buffered and protected, which greatly improves the safety during transportation and movement, and has a good effect.
