Description

Technical Field

[0001] This utility model relates to the field of camera technology, specifically to a camera device that is resistant to dust and high temperatures. Background Technology

[0002] The high temperature and high dust environment in industrial sites is a weakness of surveillance cameras. If the installation environment is a high temperature, high pressure, high dust, or flammable and explosive place, the video surveillance camera installed in such an environment is prone to the following problems: the monitoring picture becomes blurry after dust falls on the lens, and the circuit board ages under high temperature, which makes the camera easy to be damaged, requiring frequent replacement of spare parts or regular cleaning.

[0003] A camera with dustproof and high-temperature air curtain technology is available. This technology provides protective airflow in high-temperature and high-dust environments, reducing the temperature around the camera and preventing dust from adhering to the outer wall of the transparent cover. This dustproof and high-temperature air curtain camera uses a fan to deliver external air into and exhaust it for heat dissipation and dust prevention. However, in high-dust environments, as air continuously flows between the camera and the airflow guide, dust particles can adhere to the outside of the camera, affecting heat dissipation. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems mentioned above, and provides a camera device that is dustproof and heatproof, which can clean the outer peripheral surface of the camera to prevent dust adhering to the outer peripheral surface of the camera from affecting the heat dissipation of the camera.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust- and high-temperature resistant camera device includes a housing, a camera body, and a cleaning mechanism. The camera body is installed inside the housing. The cleaning mechanism includes a cleaning component and a cleaning drive component. The cleaning component is disposed between the outer peripheral surface of the camera body and the inner wall of the housing. The cleaning drive component is connected to the cleaning component to drive the cleaning component to reciprocate along the outer peripheral surface of the camera body, thereby cleaning the outer peripheral surface of the camera body.

[0007] Furthermore, the outer casing encloses a mounting cavity, a first port, and a second port, both of which communicate with the mounting cavity and are located at opposite ends of the outer casing. The camera body is installed within the mounting cavity, with its lens facing the second port. The camera device includes a filter assembly, an isolation mesh assembly, and a fan. The filter assembly is installed at the first port, the isolation mesh assembly is installed at the second port, the fan is installed within the mounting cavity and located between the camera body and the filter assembly, and the cleaning component is housed within the mounting cavity and spaced apart from the inner wall of the outer casing to form an air guide channel.

[0008] Furthermore, the fan includes a motor and fan blades. The motor is installed in the mounting cavity, and the fan blades are installed on the motor shaft of the motor to draw air from the first port into the mounting cavity.

[0009] Furthermore, the cleaning drive component includes a reciprocating lead screw located within the mounting cavity, a slider slidably sleeved on and cooperating with the reciprocating lead screw, and a transmission component connecting the motor shaft of the motor to the reciprocating lead screw. The two ends of the reciprocating lead screw are rotatably connected to the housing, and the cleaning component is fixedly connected to the slider. When the reciprocating lead screw rotates, the cooperation between the reciprocating lead screw and the slider drives the cleaning component to reciprocate along the axial direction of the reciprocating lead screw, thereby cleaning the outer peripheral surface of the camera body.

[0010] Furthermore, the camera device includes two spaced-apart fans; the cleaning drive includes two reciprocating lead screws, two sliders that cooperate with the two reciprocating lead screws respectively, and two transmission components that correspond to the two reciprocating lead screws respectively. The two reciprocating lead screws are respectively located on opposite sides of the camera body, and the two reciprocating lead screws are respectively connected to the motor shafts of the two motors through the corresponding transmission components; the cleaning component includes two brush plates, and the two brush plates are respectively connected to the two sliders.

[0011] Furthermore, each of the brush plates includes a plate body fixedly connected to the slider and a soft brush fixedly connected to the plate body. The slider is threadedly connected to the corresponding reciprocating lead screw. The plate body is surrounded to form a groove. The grooves of the two brush plates form a positioning groove sleeved on the outside of the camera body. The soft brush is fixed on the groove wall corresponding to the groove and contacts the outer peripheral surface of the camera body.

[0012] Furthermore, the filter assembly includes a mounting base and a filter cover, the filter cover being mounted on the first port of the housing via the mounting base.

[0013] Furthermore, the camera device also includes a filter cleaning mechanism, which includes a connecting shaft and at least one scraper. The connecting shaft passes through the filter cover and is rotatably mounted in the mounting cavity at one end. The connecting shaft is connected to the motor shaft of the motor through a linkage. At least one scraper is fixed to the end of the connecting shaft located outside the mounting cavity and contacts the outer surface of the filter cover.

[0014] Furthermore, the isolation net assembly includes a conical cover and an isolation net. The conical cover is a conical cover with openings at both ends. The conical cover is disposed between the lens of the camera body and the second port. The larger end of the opening of the conical cover is fixedly connected to the second port. The conical cover has a plurality of air supply holes spaced apart along the circumference, which communicate with the air guide channel. The isolation net is fixed on the conical cover and located on the side of the camera body away from the first port.

[0015] Furthermore, the length of the camera body is less than the length of the outer casing, and the camera body is mounted in the mounting cavity by a bracket, while the outer casing is provided with a maintenance flip cover.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The aforementioned dust-proof and high-temperature-proof camera device is equipped with a cleaning mechanism. The cleaning mechanism's cleaning drive component can drive the cleaning component to move along the outer peripheral surface of the camera body, thereby cleaning the outer peripheral surface of the camera body and preventing dust adhering to the outer peripheral surface of the camera from affecting the camera's heat dissipation.

[0018] 2. The aforementioned dust- and high-temperature-resistant camera device, by incorporating a fan, can introduce air into the housing to dissipate heat from the camera body inside. Filter assemblies and isolation mesh assemblies are installed at the first and second ports of the housing, which can filter the air introduced into the housing, reducing the adhesion of dust in the air to the outer periphery of the camera body. In addition, a scraper can clean the outer surface of the filter cover to keep it unobstructed, allowing for faster airflow and further improving heat dissipation efficiency.

[0019] 3. The aforementioned dust and high temperature protection camera device has a brush plate connected to the motor shaft of the motor through a transmission component, and a scraper connected to the motor shaft of the motor through a linkage component. Thus, when the fan is running, the brush plate and scraper are driven by the transmission component and linkage component to perform cleaning operations, eliminating the need for manual cleaning and making it more convenient to use.

[0020] 4. The aforementioned dust and high-temperature protection camera device includes a conical hood and a protective mesh. The conical hood is circumferentially spaced with several air supply holes that communicate with the air duct. In use, air passes through the air duct on the outside of the camera body, carrying heat to the air supply holes and then outward from the air supply holes. Under the action of the conical hood, the output air is obliquely ejected and converges in front of the lens of the camera body, thereby forming a positive pressure in front of the lens of the camera body. External dust-laden air is difficult to enter this positive pressure area, thereby reducing the accumulation of fine dust in the exhaust gas at the lens of the camera body, improving the dustproof effect, and thus improving the practicality of the camera device.

[0030] Please see Figure 1 A preferred embodiment of this utility model provides a dust-proof and high-temperature-proof camera device 100, including a housing 10, a camera body 30, and a cleaning mechanism 50. The camera body 30 is installed inside the housing 10. The cleaning mechanism 50 includes a cleaning component 51 and a cleaning drive component 53. The cleaning component 51 is disposed between the outer peripheral surface of the camera body 30 and the inner wall of the housing 10. The cleaning drive component 53 is connected to the cleaning component 51 to drive the cleaning component 51 to reciprocate along the outer peripheral surface of the camera body 30, thereby cleaning the outer peripheral surface of the camera body 30.

[0031] In this embodiment, the outer casing 10 surrounds a mounting cavity 11, a first port 13, and a second port 15. Both the first port 13 and the second port 15 communicate with the mounting cavity 11 and are located at opposite ends of the outer casing 10. In this embodiment, a maintenance flip cover (not shown) is provided on the outer casing 10. The maintenance flip cover is movably connected to the outer casing 10 via rotation or other means, allowing the outer casing 10 to be opened for maintenance of the components inside. The length of the camera body 30 is less than the length of the outer casing 10. The camera body 30 is installed within the mounting cavity 11, with its lens 31 facing the second port 15. The structure of the camera body 30 is prior art; the camera body 30 can be fixed within the mounting cavity 11 by a bracket (not shown), which will not be described further here for brevity.

[0032] The camera device 100 includes a fan 60, a filter assembly 70, and an isolation mesh assembly 80. The filter assembly 70 is installed at the first port 13, and the isolation mesh assembly 80 is installed at the second port 15. The fan 60 is installed in the mounting cavity 11 and is located between the camera body 30 and the filter assembly 70.

[0033] The fan 60 includes a motor 61 and a fan blade 63. The motor 61 is installed in the mounting cavity 11, and the fan blade 63 is installed on the motor shaft (not shown) of the motor 61 to draw air from the first port 13 into the mounting cavity 11. In this embodiment, the camera device 100 includes two spaced-apart fans 60, and the motor body (not shown) of the motor 61 is fixed to the end face of the camera body 30 facing the first port 13. It is understood that in other embodiments, the motor body of the motor 61 may also be fixed in the mounting cavity 11 by a bracket.

[0034] The filter assembly 70 includes a mounting base 71 and a filter cover 73, the filter cover 73 being mounted on the first port 13 of the housing 10 via the mounting base 71. Please refer to [other locations]. Figure 3 In this embodiment, the mounting base 71 includes a mounting ring 711 and two partitions 713. One end of the mounting ring 711 is fixed to the first port 13. The two partitions 713 are arranged in parallel and spaced apart, and both ends of each partition 713 are fixedly connected to the inner circumferential surface of the mounting ring 711. The filter cover 73 is a conical mesh cover. The inner side of the filter cover 73 is fixedly connected to the end face of the mounting ring 711 away from the first port 13 and the partitions 713, and completely blocks the first port 13, thereby filtering the air entering the first port 13. A mounting hole 731 is provided at approximately the middle position of the filter cover 73.

[0035] The camera device 100 also includes a filter cleaning mechanism 90, which cleans the outer surface of the filter cover 73 to prevent the mesh of the filter cover 73 from being clogged by adhering dust. Please refer to [further details omitted]. Figure 4In this embodiment, the filter cleaning mechanism 90 includes a connecting shaft 91 and at least one scraper 92. The connecting shaft 91 passes through the mounting hole 731 of the filter cover 73 and is rotatably mounted in the mounting cavity 11 at one end. In this embodiment, the connecting shaft 91 is located between the two fans 60 and passes through the gap between the two partitions 713. The end of the connecting shaft 91 located in the mounting cavity 11 is rotatably connected to the end face of the camera body 30 facing the first port 13. It can be understood that in other embodiments, the end of the connecting shaft 91 located in the mounting cavity 11 can also be rotatably mounted in the mounting cavity 11 by a bracket. The connecting shaft 91 is connected to the motor shaft of the motor 61 through a linkage 94 so that it rotates under the drive of the motor 61. For details, please refer to [link to relevant documentation]. Figure 2 The linkage 94 includes two drive wheels 941, one driven wheel 942, and a drive belt 943. The two drive wheels 941 are respectively sleeved on the motor shafts of the two motors 61, and the driven wheel 942 is sleeved on the connecting shaft 91. In this embodiment, the drive wheel 941 can be fixed on the motor shaft of the motor 61 by a shoulder retaining ring. Specifically, the motor shaft of the motor 61 has a shoulder (not shown in the figure). The drive wheel 941 is sleeved on the motor shaft of the motor 61 and located on one side of the shoulder. Then, the other end of the drive wheel 941 facing away from the shoulder is axially fixed by an elastic retaining ring or a shaft end retaining ring, so that the drive wheel 941 is limited between the retaining ring and the shoulder, preventing the drive wheel 941 from moving axially during the rotation of the motor shaft. Similarly, the driven wheel 942 can also be fixed to the connecting shaft 91 by means of a shoulder retaining ring. Specifically, the connecting shaft 91 has a shoulder (not shown in the figure), the driven wheel 942 is fitted onto the connecting shaft 91 and located on one side of the shoulder, and then the other end of the driven wheel 942 facing away from the shoulder is axially fixed by an elastic retaining ring or a shaft end retaining ring, so that the driven wheel 942 is limited between the retaining ring and the shoulder, preventing the driven wheel 942 from moving axially during rotation. The drive belt 943 is wound around the two drive wheels 941 and the driven wheel 942. The drive wheels 941 and the driven wheel 942 can be existing pulleys, and the drive belt 943 is a belt used in conjunction with the pulleys. The use of a shoulder retaining ring to fix the pulleys is existing technology, and will not be described in detail here for brevity. When the motor shaft of the motor 61 rotates, the drive wheels 941, the drive belt 943 and the driven wheel 942 can drive the connecting shaft 91 to rotate. At least one scraper 92 is fixed to one end of the connecting shaft 91 located outside the mounting cavity 11 and contacts the outer surface of the filter cover 73. In this embodiment, the scraper 92 is inclined relative to the connecting shaft 91 so as to contact the outer surface of the filter cover 73. When the connecting shaft 91 rotates, it can drive the scraper 92 to rotate together, thereby enabling the scraper 92 to clean different parts of the outer surface of the filter cover 73.

[0036] Please see again Figure 1The isolation net assembly 80 includes a conical cover 81 and an isolation net 83. In this embodiment, the conical cover 81 is a conical cover with openings at both ends. The conical cover 81 is disposed between the lens 31 of the camera body 30 and the second port 15, and the larger end of the opening of the conical cover 81 is fixedly connected to the second port 15. A plurality of air holes 811 are spaced apart along the circumferential direction on the conical cover 81. The isolation net 83 is fixed to the conical cover 81 and is located on the side of the camera body 30 away from the first port 13.

[0037] The cleaning drive unit 53 includes reciprocating lead screws 531 all located within the mounting cavity 11, sliders 511 slidably sleeved on and cooperating with the reciprocating lead screws 531, and transmission components 534 connecting the motor shaft of the motor 61 to the reciprocating lead screws 531. In this embodiment, the cleaning drive unit 53 includes two reciprocating lead screws 531, two sliders 511 respectively cooperating with the two reciprocating lead screws 531, and two transmission components 534 respectively corresponding to the two reciprocating lead screws 531. The two reciprocating lead screws 531 are respectively located on opposite sides of the camera body 30, and both ends of the reciprocating lead screws 531 are rotatably connected to the housing 10. The two reciprocating lead screws 531 are respectively connected to the motor shafts of the two motors 61 through the corresponding transmission components 534. The reciprocating lead screws 531 are connected to the motor shafts of the motors 61 through the transmission components 534 to rotate under the drive of the fan 60. Specifically, the transmission component 534 includes a driving wheel 535, a driven wheel 536, and a transmission belt 537. The driving wheels 535 of the two transmission components 534 are respectively sleeved on the motor shafts of the two motors 61 and located between the drive wheel 941 and the motor body of the motor 61. In this embodiment, the driving wheel 535 can be fixed on the motor shaft of the motor 61 by means of a shoulder retaining ring. Specifically, the motor shaft of the motor 61 has a shoulder (not shown in the figure). The driving wheel 535 is sleeved on the motor shaft of the motor 61 and located on one side of the shoulder. Then, the other end of the driving wheel 535 facing away from the corresponding shoulder is axially fixed by an elastic retaining ring or a shaft end retaining ring, so that the driving wheel 535 is limited between the corresponding retaining ring and the shoulder, preventing the driving wheel 535 from moving axially during the rotation of the motor shaft. The driven wheels 942 of the two transmission components 534 are fixedly sleeved on the two reciprocating lead screws 531, and the transmission belt 537 is wound around the corresponding driving wheel 535 and driven wheel 536. The driving wheel 535 and driven wheel 536 can be existing pulleys, and the transmission belt 537 is a belt used in conjunction with the pulleys. When the motor shaft of the motor 61 rotates, the corresponding reciprocating lead screw 531 can be driven to rotate by the cooperation of the driving wheel 535, the transmission belt 537 and the driven wheel 536. The structure of the reciprocating lead screw 531 is existing technology. The reciprocating lead screw 531 is a form of three-dimensional cam pair, and its outer circumferential surface has two threaded grooves with the same pitch and opposite directions of rotation. The two ends of the two threaded grooves are connected by a transition curve. In this embodiment, the slider 511 is slidably sleeved on the corresponding reciprocating lead screw 531, and the slider 511 is provided with a guide rod 516 that slidably engages with the threaded groove of the reciprocating lead screw 531. When the reciprocating screw 531 rotates, it can push the guide rod 516 placed in the spiral groove and the slider 511 together to reciprocate along the axial direction of the reciprocating screw 531 through the side of the spiral groove. At the same time, through the cooperation of the reciprocating screw 531 and the slider 511, the slider 511 can reciprocate along the axial direction of the reciprocating screw 531 when the motor shaft of the motor 61 rotates in one direction, so that the fan 60 is always a positive pressure fan, ensuring that air always enters from the first port 13.

[0038] The cleaning component 51 is housed within the mounting cavity 11 and spaced apart from the inner wall of the outer casing 10 to form an air guide channel (not shown). In this embodiment, the cleaning component 51 is connected to the slider 511 so that it reciprocates along the axial direction of the reciprocating screw 531 when the reciprocating screw 531 rotates, thereby cleaning the outer peripheral surface of the camera body 30. For details, please refer to [link to relevant documentation]. Figure 5 The cleaning component 51 includes two brush plates 510, which are fixedly connected to two sliders 511 respectively. Each brush plate 510 includes a plate body 512 fixed to the corresponding slider 511 and a soft brush 515 fixed to the side of the plate body 512 facing the camera body 30. The plate body 512 forms a groove 513, and the grooves 513 of the two brush plates 510 form a positioning groove (not shown) that fits around the camera body 30. The side of the plate body 512 facing away from the groove 513 is spaced apart from the inner wall of the outer casing 10 to form an air guide channel. The soft brush 515 is fixed to the groove wall of the corresponding groove 513 and contacts the outer peripheral surface of the camera body 30.

[0039] When the camera device 100 is in use, two sets of motors 61 are activated, driving the fan blades 63 to rotate. This allows outside air to be drawn into the housing 10 through the first port 13, while impurities in the air are filtered onto the outside of the filter cover 73. The air entering the housing 10 flows along the air guide channel toward the second port 15 and is finally discharged from the air outlet 811. During this process, the air passes over the outside of the camera body 30, transferring heat to the air outlet 811 and outputting it outward from the air outlet 811, achieving a heat dissipation effect. In addition, under the action of the conical cover 81, the air output from the air outlet 811 is discharged outward at an angle and converges in front of the lens of the camera body 30, thereby creating a positive pressure in front of the lens of the camera body 30. This makes it difficult for dusty air from the outside to enter this positive pressure area, thereby reducing the accumulation of fine dust in the exhaust air at the lens of the camera body 30 and improving the dustproof effect.

[0040] When motor 61 operates, it drives connecting shaft 91 and reciprocating screw 531 to rotate synchronously via transmission component 534 and linkage component 94. Simultaneously, the rotation of connecting shaft 91 drives scraper 92 to rotate, cleaning dust adhering to the outside of filter cover 73 and allowing air to quickly pass through the mesh of filter cover 73 into housing 10. Due to the limiting effect of the space enclosed by housing 10 and camera body 30, brush plate 510 cannot rotate with reciprocating screw 531. Therefore, when reciprocating screw 531 rotates, slider 511 moves back and forth inside housing 10 along the axial direction of reciprocating screw 531, i.e., the length direction of camera body 30, causing the soft brush 515 of brush plate 510 to clean the outer peripheral surface of camera body 30, preventing excessive dust from adhering to the outer peripheral surface and affecting heat dissipation. The dust swept off by brush plate 510 falls to the bottom of housing 10 under gravity, and can be cleaned periodically by opening the maintenance cover.

[0041] The aforementioned dust and high temperature resistant camera device 100 is equipped with a cleaning mechanism 50. The cleaning drive component 53 of the cleaning mechanism 50 can drive the cleaning component 51 to move along the outer peripheral surface of the camera body 30, thereby cleaning the outer peripheral surface of the camera body 30 and preventing dust adhering to the outer peripheral side of the camera from affecting the heat dissipation of the camera.

[0042] The aforementioned dust and high-temperature resistant camera device 100, by means of a fan 60, can introduce air into the housing 10 to dissipate heat from the camera body 30 inside the housing 10; a filter assembly 70 and an isolation mesh assembly 80 are installed at the first port 13 and the second port 15 of the housing 10, which can filter the air introduced into the housing 10 and reduce the adhesion of dust in the air to the outer peripheral surface of the camera body 30; in addition, a scraper 92 can clean the outer surface of the filter cover 73 to keep the filter cover 73 unobstructed, so that the airflow speed is faster and further improves the heat dissipation efficiency.

[0043] The aforementioned dust and high temperature resistant camera device 100 has a brush plate 510 connected to the motor shaft of the motor 61 via a transmission component 534, and a scraper 92 connected to the motor shaft of the motor 61 via a linkage component 94. Thus, when the fan 60 is running, the brush plate 510 and the scraper 92 are driven by the transmission component 534 and the linkage component 94 to perform cleaning operations, eliminating the need for manual cleaning and making it more convenient to use.

[0044] The aforementioned dust and high temperature protection camera device 100 and the isolation net 83 provide protection during normal shutdown, preventing dust and impurities from flowing back from the second port 15 into the interior of the housing 10, thus improving the protection effect.

However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
