Description

Technical Field

[0001] The invention relates to the technical field of infrared integrated cameras, in particular to an outdoor gun-type infrared integrated camera. Background Art

[0002] There are many types of cameras, including waterproof digital cameras, and their basic working principles are the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected from the object is collected by the camera lens and focused on the light-receiving surface of the camera device (such as the target surface of the camera tube). The camera device then converts the light into electrical energy, which is a "video signal". The photoelectric signal is very weak and needs to be amplified by a pre-amplifier circuit, and then processed and adjusted by various circuits. The final standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or sent to a monitor for display.

[0003] Most outdoor infrared cameras on the market dissipate heat in two ways:

[0004] The first heat dissipation method is to dissipate heat for the infrared integrated camera by opening a plurality of heat dissipation slots on the outer side of the infrared integrated camera. Although the infrared integrated camera with this heat dissipation method can work in any scene, this heat dissipation method has low heat dissipation efficiency for the infrared integrated camera body and is not convenient for dissipating heat for the infrared integrated camera.

[0005] The second heat dissipation method is to open a heat dissipation hole on the infrared integrated camera body, and set a heat dissipation fan at the opening of the heat dissipation hole to accelerate the exchange of air inside the infrared integrated camera body and external air for heat dissipation. By directly exchanging the air inside the infrared integrated camera body with the external air, the heat dissipation efficiency of the infrared integrated camera is accelerated. However, when this heat dissipation method is used in rainy days or dusty environments, air containing moisture or dust will directly enter the infrared integrated camera and accumulate on the internal components of the camera, causing aging or even damage of the components.

[0006] Therefore, when using an infrared integrated camera in an environment with a high dust content in the air, only the camera with the first heat dissipation method can be used. However, the heat dissipation efficiency of the camera with this heat dissipation method is low. Although it can work in an environment with a lot of dust or high moisture content in the air, working for a long time in a dusty environment will cause a large amount of heat to accumulate inside the camera, accelerate the rapid aging of the internal components of the camera, and even cause damage to the camera.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0032] See also Figure 1-10 An outdoor gun-type infrared integrated camera comprises a gun-type camera body 2 installed by a mounting bracket 1, an infrared module arranged on an end face of one end of the camera body 2 lens, and a heat dissipation mechanism arranged on the camera body 2, a working groove 9 is provided on an end face of the camera body 2 away from the lens, and a sealingly connected mounting plate 10 is detachably mounted at the opening position of the working groove 9, the heat dissipation mechanism comprises two compression blocks 17 which are parallel to each other and symmetrically arranged on the symmetrical groove walls on both sides of the working groove 9, a control column 35 which is arranged on the side of each compression block 17 close to and away from the mounting plate 10 and is connected to the inside of the compression block 17, a compression assembly which is arranged in the working groove 9 and circulates and compresses the air inside the two compression blocks 17 to release heat, and a plurality of heat dissipation strips 4 which are fixedly arranged on the end faces of the two compression blocks 17 away from each other and sealably penetrate the outside of the camera body 2, and the two control columns 35 arranged on each compression block 17 are used to control the air in the working groove 9 to enter or discharge the compression block 17; the heat dissipation strip 4 is made of copper strip.

[0033] When the mounting plate 10 is mounted on the opening of the working slot 9 , the working slot 9 is sealed, thereby preventing external dust and moisture from entering the camera body 2 .

[0034] like Figure 1-10As shown, the camera body 2 is directly installed through the mounting bracket 1 (installed on a wall, a street lamp pole, etc.), and the infrared module on the camera body 2 will release heat when working. In the prior art, a groove is opened on the side of the infrared integrated camera body to speed up the heat dissipation efficiency of the infrared integrated camera, but the heat dissipation efficiency of this heat dissipation method is still relatively low, or a heat dissipation hole is opened on the infrared integrated camera, and a heat dissipation fan blade is set on the heat dissipation hole to speed up the exchange of air between the inside and outside of the infrared integrated camera, thereby achieving heat dissipation of the infrared integrated camera. However, this heat dissipation method needs to filter dust in the air on the one hand to prevent dust in the external air from entering the inside of the infrared integrated camera, and on the other hand, moisture in the external air will also enter the inside of the infrared integrated camera and liquefy, causing internal components of the infrared integrated camera to be damaged by water droplets.

[0035] When the camera body 2 of the present application is used in an environment where there is a lot of moisture or dust in the air, a compression block 17 is arranged in the working groove 9, and a heat sink 4 with one end passing through the outside of the camera body 2 is arranged on the side of the compression block 17, and the air circulation inside the camera body 2 is controlled by the control column 35 arranged on the compression block 17 to enter the compression block 17, and the air in the compression block 17 is compressed by the compression component arranged in the working groove 9, the air volume is reduced and the temperature rises, which facilitates the heat in the air inside the compression block 17 to be transferred to the heat sink 4, that is, the heat can be dissipated to the outside of the camera body 2 through the heat sink 4 passing through the outside of the camera body 2, and the compressed air in the compression block 17 facilitates the heat dissipation of the inside of the camera body 2, and the compressed air is discharged into the working groove 9 again, at this time, the air pressure is reduced, the volume is increased, and the temperature is reduced, compared with the lowered air temperature in the working groove 9, so that the air in the working groove 9 is circulated and cooled, which can conveniently dissipate the heat of the infrared integrated camera, improve the heat dissipation efficiency of the camera body, and avoid the air outside the camera body 2 entering the camera body 2, and the moisture or dust in the outside air entering the camera body 2.

[0036] The compression block 17 is connected to the air intake assembly and the exhaust assembly respectively through two control columns 35. Through holes 26 are provided on the end faces of both ends of the control column 35, and a control hole that passes through the two through holes 26 is provided in the control column 35. A plurality of through grooves 29 are provided on the wall of the control hole along the axial direction of the control column 35 in the length direction. A sealing block 30 is slidably arranged in the control hole, and the sealing block 30 is arranged in the control hole through a control member.

[0037] The control component includes a first control structure arranged in the control column 35 connected to the air intake component, and a second control structure arranged in the control column 35 connected to the exhaust component. The first control structure includes a telescopic rod 27 which is penetrated in the control hole along the axial direction of the control column 35 and one end of which is vertically connected to the sealing block 30 adjacent to the end surface of one end of the compression block 17 and the opening position of the through hole 26, a compression spring 28 which is movably sleeved on the rod body of the telescopic rod 27 and whose two ends are respectively connected to the two ends of the telescopic rod 27, and two electromagnets arranged on the two end ends of the telescopic rod 27.

[0038] like Figure 1-4 and Figure 7 As shown, when the heat is dissipated inside the working groove 9, the magnetic poles of the adjacent ends of the two electromagnets are controlled to be opposite so that the two electromagnets are close to each other, and the compression spring 28 provided on the rod body of the telescopic rod 27 is compressed, so as to facilitate the sealing block 30 to slide in the control hole. When the sealing block 30 moves to the middle position in the control hole, the through groove 29 opened through the wall of the control hole facilitates the internal air of the working groove 9 introduced by the air intake component to be introduced into the compression block 17 through the through groove 29, and cooperates with the compression component to compress the air in the compression block 17 to release heat, so as to facilitate the heat dissipation of the camera body 2.

[0039] The second control structure includes a telescopic rod 27 which is inserted into the control hole along the axial direction of the control column 35 and one end of which is perpendicularly connected to the end surface of the sealing block 30 away from the end of the compression block 17 and the opening position of the through hole 26, and a compression spring 28 which is movably sleeved on the body of the telescopic rod 27 and has two ends respectively connected to the two ends of the telescopic rod 27.

[0040] like Figure 1-4 and Figure 7 As shown, when the air in the compression block 17 is compressed and released by the compression component, and when the compression strength of the air in the compression block 17 reaches a fixed value, the pressure in the compression block 17 will push the sealing block 30 in the control hole in the control column 35 connected to the exhaust component to slide, that is, compress the compression spring 28 on the rod body of the telescopic rod 27. At this time, the air in the compression block 17 will be introduced into the exhaust component through the through groove 29 opened in the wall of the control hole. At this time, the internal heat of the exhausted air is transferred to the heat dissipation strip 4 when entering the compression, thereby dissipating the heat inside the working groove 9 and improving the heat dissipation efficiency of the camera body 2.

[0041] The air intake assembly includes two air intake pipes 14 arranged in the working groove 9 and arranged in the vertical direction, a second conduit 13 arranged between adjacent air intake pipes 14 and control columns 35 and connecting the air intake pipes 14 and the interior of the control columns 35, and an air suction member arranged on the second conduit 13. The control column 35 rod body is provided with a plurality of air intake holes 15 connecting the interior of the control column 35 along the length direction.

[0042] The vacuum pump uses a vacuum fan blade, which is driven by a motor to drive the air in the second duct 13 to flow, thereby facilitating the air in the working tank 9 to enter the compression block 17, and facilitating the subsequent compression of the air in the compression block 17 through the compression component to release heat.

[0043] The exhaust assembly includes an exhaust plate 12 arranged in the vertical direction near the opening position of the working groove 9, and a first conduit 11 arranged between the exhaust plate 12 and the control column 35 and connected to the exhaust plate 12 and the control column 35 at both ends. The end surface of the exhaust plate 12 near the first conduit 11 is provided with a plurality of exhaust grooves 18 arranged in the vertical direction at equal intervals in the horizontal direction and in the direction of the opening length.

[0044] like Figure 4 As shown, after the air is compressed and releases heat in the compression block 17, it is introduced into the exhaust plate 12 through the first conduit 11, and the air after releasing heat is evenly discharged into the working groove 9 through the exhaust groove 18 opened on the exhaust plate 12, thereby facilitating uniform heat dissipation inside the camera body 2.

[0045] The heat dissipation mechanism also includes a sealing ring 3 fixedly arranged on the lens end face of the camera body 2 and sleeved on the lens, two transparent disks 31 arranged in parallel inside the inner ring of the sealing ring 3, a limit strip 32 arranged between the two transparent disks 31 and symmetrically arranged on the left and right, and two third conduits 34 with one end sealingly passing through one of the transparent disks 31 and the other end passing through the working groove 9, and an electromagnetic valve 16 connecting the end of one of the third conduits 34 with the inside of one of the air inlet pipes 14. A plurality of second limit slots 33 are provided on the adjacent side surfaces of the two limit strips 32 at equal intervals along the length direction.

[0046] like Figure 1-4 and Figure 8 As shown, when the camera body 2 is working under the condition of low external temperature, water mist will condense on the lens of the camera body 2, blocking the lens of the camera body 2, making it inconvenient for the camera body 2 to collect video data. At this time, the solenoid valve 16 is opened, and the compression block 17 will draw out the air between the two transparent disks 31 through the third tube 34 when sucking air through the second conduit 13. At the same time, another third conduit 34 can also suck the air with high temperature in the working tank 9 into the two transparent disks 31. The temperature in the air is transferred to the transparent disk 31 to evaporate the water mist condensed on the surface of the transparent disk 31, so that the air temperature drops, thereby facilitating the camera body 2 to stably and accurately collect video data through the lens, and ensuring that the subsequent air is circulated into the working tank 9 again, so as to facilitate the heat dissipation of the air in the working tank 9.

[0047] The compression assembly includes two compression tubes 19 whose ends are fixedly arranged on the adjacent end faces of the two compression blocks 17 away from each other and pass through the interior of the compression blocks 17, a compression slider 20 that is sealingly slidably penetrates the inner wall of the compression tube 19, and a compression member that is arranged in the working groove 9 and controls the two compression sliders 20 to slide back and forth synchronously in the inner wall of the compression tube 19.

[0048] The compression member includes two connecting rods 25 with U-shaped structures and opening directions opposite to each other and located at the lower ends of the rod bodies, which are fixedly connected to different compression sliders 20, two limiting columns 24 arranged in the vertical direction and with the bottom ends fixedly arranged at the upper ends of the two connecting rods 25, and a rotating disk 22 arranged horizontally above the two connecting rods 25 and driven by a rotating motor 21. The rotating disk 22 is provided with four first limiting grooves 23 with an arc-shaped structure in the opening length direction and interpenetrating with each other on the end surface adjacent to one end of the connecting rod 25, and the adjacent sides of the opening positions of the four first limiting grooves 23 are close to each other.

[0049] like Figure 3-6 and Figure 9-10 As shown, the rotating disk 22 is driven to rotate by the rotating motor 21, which can drive the limiting column 24 inserted in the first limiting groove 23 to slide along the first limiting groove 23. At this time, the compression slider 20 inserted in the compression tube 19 is driven to slide back and forth by two U-shaped connecting rods 25. When the compression slider 20 moves toward the compression block 17, the compression slider 20 slides to compress the air in the compression block 17 to release heat, and the released heat is transferred to the heat dissipation strip 4, so that the heat dissipation strip 4 located outside the camera body 2 is convenient for heat dissipation, thereby improving the heat dissipation efficiency of the camera body 2.

[0050] The process of the compression slider 20 sliding in the compression tube 19 is as follows:

[0051] 1. When the compression slider 20 moves in the compression tube 19 in the direction away from the compression block 17, the air pressure in the compression block 17 is reduced. At this time, the sealing blocks 30 in the two control columns 35 on the compression block 17 will move toward the compression block 17. The control column 35 connected to the exhaust component will abut against the end surface of the through hole 26. Under the action of the two electromagnets, the control column 35 connected to the intake component controls the magnetic poles of the two adjacent ends of the electromagnets to be opposite. The two electromagnets are brought closer to each other to compress the compression spring 28, so that the air in the intake component can enter the compression block 17 through the through groove 29, which is convenient for the subsequent compression of the air in the compression block 17.

[0052] 2. When the compression slider 20 moves in the compression tube 19 toward the compression block 17, the air pressure in the compression block 17 increases. At this time, the sealing blocks 30 in the two control columns 35 on the compression block 17 will move away from the compression block 17. The control column 35 connected to the air intake assembly will rest against the end face of the through hole 26. When the air in the compression block 17 completes heat release and the pressure reaches the maximum, the sealing block 30 connected to the exhaust assembly will slide in the control hole to compress the compression spring 28. When the sealing block 30 moves to the middle of the control hole, the air in the compression block 17 can move to the discharge assembly through the through groove 29 for discharge.

[0053] In summary, the air in the working slot 9 circulates into the compression block 17 for circulation compression and heat dissipation, thereby facilitating heat dissipation of the camera body 2 .

[0054] The heat dissipation mechanism also includes a guide bar 5 fixedly arranged on the side of the camera body 2 and with a length direction perpendicular to the length direction of the heat dissipation bar 4, a heat dissipation block 8 arranged on the side of the bottom side of the camera body 2, a heat dissipation fan blade arranged in a heat dissipation hole opened at the end of the heat dissipation block 8, and a guide tube 7 with one end connected to the opening of the heat dissipation hole and the other end connected to the middle of the side of the guide bar 5. A plurality of guide grooves 6 are opened on the side of the guide bar 5 adjacent to the heat dissipation bar 4 at equal intervals along the length direction.

[0055] like Figure 1-2 As shown, the heat dissipation fan blades rotate to facilitate the external air of the camera body 2 to be introduced into the guide strip 5 through the guide tube 7, and then to be ejected through the guide groove 6 provided on the side of the guide strip 5, so that the heat loss on the heat dissipation strip 4 is accelerated by the ejected air, thereby facilitating the heat dissipation of the camera body 2.

[0056] In the present application, the working tank 9 is made into a sealed space, and the air itself is circulated and cooled, thereby preventing the exchange of external air and the air in the camera body 2 from causing external moisture or dust to enter the working tank 9.

[0057] The process of cooling the working tank 9 in this application is as follows:

[0058] The magnetic poles of the adjacent ends of the two electromagnets are controlled to be the same, and the compression spring 28 set on the rod body of the telescopic rod 27 is compressed by the two electromagnets approaching each other, and the sealing block 30 slides to the middle position of the control hole. The through holes 26 at both ends of the control column 35 are connected through the through groove 29, and then the air intake blades set on the second duct 13 rotate to drive the air with higher temperature in the working groove 9 to enter the compression block 17 through the second duct 13 and the control column 35, and the compression slider 20 moves into the compression tube 19. At this time, the air in the compression block 17 is compressed, the air volume is reduced, and the air temperature rises, which speeds up the rate at which the air temperature is transferred to the heat dissipation strip 4 (and the surface of the compression block 17 is provided with heat insulation material, such as ultra-fine glass wool). Heat is dissipated through the heat dissipation strip 4 penetrating the outside of the camera body 2, and the pressure inside the compression block 17 reaches a certain value. When the strength is constant, the sealing block 30 in the control column 35 connected to the exhaust component will be pushed to slide. When the sealing block 30 slides to the middle position of the control hole, the two through holes 26 are connected through the through groove 29, so that the air is discharged to the exhaust component through the control column 35. After the air passes through the control column 35, the air pressure decreases, the air volume increases, and the air temperature drops to a large extent (compared with the large drop in the temperature of the air entering the air inlet end), and the air with reduced temperature is discharged into the working groove 9 through the exhaust component to reduce the temperature in the working groove 9, so that the air in the working groove 9 in a sealed space is circulated and cooled, thereby ensuring the circulation of the air in the working groove 9, and avoiding the heat dissipation method in the prior art that causes moisture or dust in the external environment to enter the camera body 2, causing damage to the camera body 2 or low heat dissipation efficiency.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
