Description

Technical Field

[0001] This invention relates to the field of infrared detection devices, specifically to an infrared detection device capable of tracking multiple targets in all directions at low altitudes. Background Technology

[0002] An infrared detector is a device that converts incident infrared radiation signals into electrical signals. In an infrared detector, a thermoelectric element detects the presence or movement of a human body and converts the output signal of the thermoelectric element into a voltage signal. Then, the voltage signal is analyzed to facilitate target detection. It can be used for real-time tracking of multiple targets such as pedestrians and vehicles in complex infrared scenes.

[0003] Most existing infrared detection devices are not easy to adjust according to the required detection range and angle, and are also difficult to clean. After long-term use, dust will accumulate on the outside and fog will form inside, thus blocking the probe's viewing angle and affecting the detection effect.

[0004] Therefore, it is necessary to invent an infrared detection device capable of tracking multiple targets in all directions at low altitudes to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a low-altitude, multi-target, omnidirectional infrared detection device. The outer wall cleaning ring helps solve the problem of dust accumulation on the outside of the transparent protective cover obstructing the view, thus avoiding detection blind spots. The inner wall cleaning ring helps prevent fogging on the inner wall, which also obstructs the view and affects the detection effect. The transmission cylinder drives the outer lifting ring to rise and fall, thereby adjusting the angle of the adjustable detector head. The detection range can be adjusted as needed. Multiple adjustable detector heads are provided for omnidirectional detection, helping to avoid monitoring blind spots. This addresses the problems of existing technologies where it is difficult to adjust the device according to the required detection range and angle, and where cleaning is often difficult. After prolonged use, dust accumulates on the outside and fogging occurs inside, obstructing the probe's viewing angle and affecting the detection effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-altitude multi-target omnidirectional tracking infrared detection device, comprising a top base and a transparent protective cover, wherein the transparent protective cover is disposed at the bottom of the top base, and a detection component is disposed inside the transparent protective cover. The detection component includes a support rod, which is fixedly connected to the top base. A column is fixedly connected to the middle of the support rod, and a fixed seat is fixedly connected to the bottom of the support rod.

A crossbeam is rotatably connected inside the column, and a driven gear that meshes with the drive gear is fixedly connected to the side of the crossbeam near the column. Transmission gears are fixedly connected to both ends of the crossbeam. An inner wall cleaning ring is hinged inside the transparent protective cover, and an outer wall cleaning ring is hinged to the outer side of the transparent protective cover. A rotating gear that meshes with the transmission gear is fixedly connected to the end of the inner wall cleaning ring.

[0007] A fixed support rod is fixedly connected to the side of the fixed base, a base is fixedly connected to the bottom of the column, a central probe is installed at the bottom of the base, an adjustable probe is hinged to the end of the fixed support rod, a second motor is installed on the top of the fixed base, a first bevel gear is fixedly connected to the output end of the second motor, a transmission cylinder is rotatably connected inside the fixed base, a second bevel gear that meshes with the first bevel gear is fixedly connected to the top of the transmission cylinder, a lifting ring is threaded to the outer side of the second bevel gear, a movable support rod is fixedly connected to the outer side of the lifting ring, a connecting block is fixedly connected to the tail end of the adjustable probe, a sliding rod is fixedly connected to the end of the connecting block, and the sliding rod is movably connected to the movable support rod.

[0008] Preferably, the inner wall cleaning ring and the outer wall cleaning ring are fixedly connected to each other by a connecting shaft, and the connecting shaft passes through the transparent protective cover to fix the inner wall cleaning ring and the outer wall cleaning ring together.

[0009] Preferably, cleaning cotton is fixedly connected to both the outer side of the inner wall cleaning ring and the inner side of the outer wall cleaning ring, and the cleaning cotton is in contact with the outer wall or interior of the transparent protective cover.

[0010] Preferably, the number of adjustable probes is set to six, and the six adjustable probes are distributed in a ring array about the center point of the column.

[0011] Preferably, the movable support rod has an internal movable groove that cooperates with the sliding rod.

[0012] Preferably, the transmission cylinder is hollow and rotatably connected to the column. A protrusion is fixedly connected to the bottom of the transmission cylinder, and a slot that mates with the protrusion is provided inside the base.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. By starting the first motor, the crossbeam is driven to rotate. The crossbeam drives the inner wall cleaning ring to rotate through the transmission gears and rotating gears at both ends.

The transmission cylinder drives the outer lifting ring and movable support rod to rise and fall, which in turn drives the sliding rod to rise and fall. The sliding rod drives the adjustable probe to rotate, thereby adjusting the angle of the adjustable probe. The detection range can be adjusted as needed, and multiple adjustable probes are provided to facilitate all-round detection and avoid monitoring blind spots. The transparent protective cover is made of acrylic organic glass, which has good transparency, chemical stability and weather resistance, and has a beautiful appearance, extending the service life of the device.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This invention provides, for example Figure 1-9The infrared detection device for low-altitude multi-target omnidirectional tracking shown includes a top base 1 and a transparent protective cover 2. The transparent protective cover 2 is located at the bottom of the top base 1. A detection component is installed inside the transparent protective cover 2. The detection component includes a support rod 3, which is fixedly connected to the top base 1. A column 4 is fixedly connected to the middle of the support rod 3. A fixed seat 5 is fixedly connected to the bottom of the support rod 3. A first motor 6 is installed on the top of the fixed seat 5. A drive gear 7 is fixedly connected to the output end of the first motor 6. A crossbeam 8 is rotatably connected inside the column 4. A driven gear 9 that meshes with the drive gear 7 is fixedly connected to the side of the crossbeam 8 near the column 4. Transmission gears 10 are fixedly connected to both ends of the crossbeam 8. An inner wall cleaning ring 11 is hinged inside the transparent protective cover 2. An outer wall cleaning ring 12 is hinged to the outside of the transparent protective cover 2. A rotating gear 14 that meshes with the transmission gear 10 is fixedly connected to the end of the inner wall cleaning ring 11.

[0033] A fixed support rod 15 is fixedly connected to the side of the fixed base 5. A base 16 is fixedly connected to the bottom of the column 4. A central probe 17 is installed at the bottom of the base 16. An adjustable probe 18 is hinged to the end of the fixed support rod 15. A second motor 19 is installed on the top of the fixed base 5. A first bevel gear 20 is fixedly connected to the output end of the second motor 19. A transmission cylinder 21 is rotatably connected inside the fixed base 5. A second bevel gear 22 that meshes with the first bevel gear 20 is fixedly connected to the top of the transmission cylinder 21. A lifting ring 23 is threadedly connected to the outer side of the second bevel gear 22. A movable support rod 24 is fixedly connected to the outer side of the lifting ring 23. A connecting block 25 is fixedly connected to the tail end of the adjustable probe 18. A sliding rod 26 is fixedly connected to the end of the connecting block 25. The sliding rod 26 is movably connected to the movable support rod 24.

[0034] The inner wall cleaning ring 11 and the outer wall cleaning ring 12 are fixedly connected to the ends of a connecting shaft 13. The connecting shaft 13 passes through the transparent protective cover 2 to fix the inner wall cleaning ring 11 and the outer wall cleaning ring 12, so as to facilitate the simultaneous movement of the inner wall cleaning ring 11 and the outer wall cleaning ring 12.

[0035] Cleaning cotton is fixedly connected to the outer side of the inner wall cleaning ring 11 and the inner side of the outer wall cleaning ring 12. The cleaning cotton is in contact with the outer wall or the inside of the transparent protective cover 2. The outer wall cleaning ring 12 helps to solve the problem of dust adhering to the outside of the transparent protective cover 2 and blocking the view, thus avoiding blind spots in the detection. The inner wall cleaning ring 11 helps to prevent fogging on the inner wall, which would obstruct the view and affect the detection effect.

[0036] The number of adjustable probes 18 is set to six, and the six adjustable probes 18 are arranged in a ring array about the center point of the column 4, which facilitates all-round detection and helps to avoid monitoring blind spots.

[0037] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the movable support rod 24 has a movable groove 27 inside. The movable groove 27 cooperates with the sliding rod 26 to provide room for the movable support rod 24 to move, which facilitates the operation of the device.

[0038] The transmission cylinder 21 is hollow and is rotatably connected to the column 4. A protrusion 28 is fixedly connected to the bottom of the transmission cylinder 21. The base 16 has a slot inside that matches the protrusion 28, which facilitates the limiting of the transmission cylinder 21.

[0039] The transparent protective cover 2 is made of acrylic plexiglass, which has good transparency, chemical stability and weather resistance, and is also aesthetically pleasing and easy to use.

[0040] The transparent protective cover 2 is semi-circular, and its diameter is larger than that of the crossbeam 8, which facilitates the protection of the device.

[0041] The top of the transparent protective cover 2 is fixedly connected to a fixing ring 29. Both the fixing ring 29 and the top seat 1 have threaded grooves inside. The threaded grooves are threaded with fixing screws 30, which facilitates the disassembly and installation of the transparent protective cover 2.

[0042] Working principle of this invention:

[0043] Refer to the instruction manual appendix Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9First, the user can attach the transparent protective cover 2 to the outside of the detection assembly, aligning the threaded hole inside the fixing ring 29 at the top of the transparent protective cover 2 with the threaded hole inside the top seat 1. Then, rotate the fixing screw 30 to fix the transparent protective cover 2 to the bottom of the top seat 1. By starting the first motor 6, the driving gear 7 is driven to rotate. The driving gear 7 drives the crossbeam 8 to rotate through the driven gear 9. The crossbeam 8 drives the rotating gear 14 to rotate through the transmission gears 10 at both ends. The rotating gear 14 is fixedly connected to the inner wall cleaning ring 11, thereby driving the inner wall cleaning ring 11 to rotate. The cleaning ring 11 is fixedly connected to the outer wall cleaning ring 12 via the connecting shaft 13, so that the inner wall cleaning ring 11 and the outer wall cleaning ring 12 rotate simultaneously. Cleaning cotton is fixedly connected to the outer side of the inner wall cleaning ring 11 and the inner side of the outer wall cleaning ring 12, and the cleaning cotton is in contact with the transparent protective cover 2, thereby cleaning the outer and inner walls of the transparent protective cover 2. The outer wall cleaning ring 12 helps to solve the problem of dust adhering to the outer side of the transparent protective cover 2 and obstructing the view, avoiding blind spots in the detection. The inner wall cleaning ring 11 helps to prevent the inner wall from fogging, obstructing the view, and affecting the detection effect.

[0044] Refer to the instruction manual appendix Figure 1-8 The user can also start the second motor 19, which drives the first bevel tooth 20 at the end to rotate. The first bevel tooth 20 drives the transmission cylinder 21 to rotate through the second bevel tooth 22. The protrusion 28 at the bottom of the transmission cylinder 21 moves inside the slot, thereby limiting the transmission cylinder 21. The transmission cylinder 21 drives the outer lifting ring 23 to rise and fall. The lifting ring 23 drives the movable support rod 24 to rise and fall synchronously, which in turn drives the sliding rod 26 to rise and fall. The sliding rod 26 drives the adjustable probe 18 to rotate. The sliding rod 26 slides inside the movable slot 27, thereby adjusting the angle of the adjustable probe 18. The detection range can be adjusted as needed. Multiple adjustable probes 18 are provided to facilitate all-round detection and help avoid monitoring blind spots.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
