Description

Technical Field

[0001] This application relates to the technical field of explosion-proof monitoring equipment, and in particular to an explosion-proof monitoring enclosure. Background Technology

[0002] Explosion-proof cameras are specialized video recording devices primarily used in flammable and explosive environments such as petroleum, chemical, and military industries. They are designed to operate normally in hazardous conditions. Therefore, explosion-proof cameras require excellent sealing to minimize the entry of flammable or explosive gases, which could then become a source of ignition.

[0003] Currently, a type of explosion-proof camera housing structure with publication number CN211378119U includes a housing and a sealing end cap. The left end of the housing is connected to the sealing end cap by fastening bolts. A fixed support frame is provided at the upper end of the housing, and a fixing block is provided at the end of the fixed support frame. An explosion-proof glass is provided at the right end of the interior of the housing, and a support rod is provided on the left side of the explosion-proof glass. This explosion-proof camera housing structure can achieve rapid and efficient heat dissipation by setting up explosion-proof glass, heat sink, heat dissipation holes, support rod, load-bearing ring and rubber pad, and utilizing the interaction between them.

[0004] Regarding the aforementioned technologies, relying on heat sinks to dissipate heat from the inside of the casing can cause the emitted heat to easily accumulate near the heat sinks. Summary of the Invention

[0005] In order to improve airflow around the enclosure and enhance its heat dissipation effect, this application provides an explosion-proof monitoring enclosure.

[0006] The explosion-proof monitoring enclosure provided in this application adopts the following technical solution: An explosion-proof monitoring enclosure, comprising: The housing contains a camera body, an active magnetic wheel, and a temperature sensor. The active magnetic wheel is rotatably connected inside the housing, and the temperature sensor is used to sense the temperature of the camera body in order to control the rotation of the active magnetic wheel. A heat dissipation assembly is sleeved on the housing. The heat dissipation assembly includes a driven magnetic wheel, which is slidably sleeved on the housing. The driven magnetic wheel is coaxially arranged with the driving magnetic wheel, and fan blades are arranged circumferentially on the driven magnetic wheel. A cleaning assembly is mounted on the housing, and the driven magnetic wheel is used to drive the cleaning assembly to clean the housing.

[0007] By adopting the above technical solution, since the explosion-proof camera is installed in a flammable and explosive environment, it is inconvenient to directly install a fan on the housing, as an external fan could easily become a source of ignition. Therefore, this application sets an active magnetic wheel inside the housing to drive its rotation. The rotation of the active magnetic wheel drives the rotation of the driven magnetic wheel, thereby driving the fan blades to rotate. During the rotation of the fan blades, the air around the housing can be circulated, thus improving the heat dissipation effect of the housing.

[0008] Meanwhile, dust easily accumulates on the upper surface of the casing, affecting its thermal conductivity and thus reducing its heat dissipation performance. Therefore, the rotation of the driven gear drives the cleaning component to clean the upper surface of the casing, reducing the impact of accumulated dust on heat dissipation.

[0009] When the temperature sensor detects that the camera body is hot, it starts the motor to drive the active magnetic wheel to rotate. The rotation of the active magnetic wheel drives the driven magnetic wheel to rotate, which in turn drives the fan blades to rotate. The rotation of the fan blades increases the airflow around the housing and enhances the heat dissipation effect of the housing.

[0010] Optionally, the cleaning assembly includes a transmission component, one end of which is connected to the driven magnetic wheel, and the other end is connected to a cleaning rod. The transmission component uses the rotation of the driven magnetic wheel to drive the cleaning rod to move on the upper surface of the housing.

[0011] By adopting the above technical solution, when the driven magnetic wheel rotates, the driven magnetic wheel uses the transmission component to drive the cleaning rod to move on the upper surface of the housing, thereby cleaning the upper surface of the housing that is prone to accumulating dust.

[0012] Optionally, the transmission component includes a driving gear, the driven magnetic wheel is provided with teeth, the driving gear meshes with the teeth on the driven magnetic wheel, the driving gear is coaxially fixedly connected to the driven gear, and the driven gear is an incomplete gear; A limiting frame is fixedly connected to the housing, and a reciprocating ring is slidably connected inside the limiting frame. The reciprocating ring is fixedly connected to the cleaning rod, and gear teeth are provided on the inner side of the reciprocating ring. The driven gear meshes with the reciprocating ring.

[0013] By adopting the above technical solution, when the driven magnetic wheel rotates, the driven magnetic wheel drives the driving gear to rotate, the driving gear rotates to drive the driven gear to rotate, the driven gear rotates to drive the reciprocating ring to reciprocate, the reciprocating ring moves to drive the cleaning rod to move, and the cleaning rod cleans the upper surface of the housing.

[0014] Optionally, a limiting seat is provided at the end of the cleaning rod away from the reciprocating ring. The limiting seat is fixedly connected to the housing, and a shielding eave extends from the side of the limiting seat away from the housing.

[0015] By adopting the above technical solution, the limiting seat reduces the lifting of the end of the cleaning rod away from the reciprocating ring, reducing the possibility of insufficient contact between the cleaning rod and the upper surface of the housing. At the same time, the shielding eaves reduce the possibility of dust adhering to the lens of the camera body.

[0016] Optionally, a connecting part is fixedly connected to the housing, the connecting part being used to mount the housing onto a wall.

[0017] By adopting the above technical solution, the connection part is designed to facilitate the installation of the housing.

[0018] Optionally, the connecting part includes a connecting screw and a connecting seat, the connecting seat being fixedly connected to the housing, and the connecting screw being hinged to the connecting seat.

[0019] By adopting the above technical solution, the screw is threaded into a pre-drilled hole, and then the angle of the camera is adjusted by the hinge between the connector and the connecting screw.

[0020] Optionally, auxiliary rings are fixedly connected to the housing and the connecting screw respectively, and a traction rope is provided between the auxiliary rings, with the traction rope passing through the two auxiliary rings.

[0021] By adopting the above technical solution, a traction rope is threaded through two auxiliary rings and then tightened, thereby maintaining an appropriate angle between the connecting seat and the connecting screw, reducing the possibility of changes in the camera angle due to unstable hinge.

[0022] Optionally, a one-way bearing is provided between the driven magnetic wheel and the housing, and the one-way bearing can rotate freely when the driving magnetic wheel drives the driven magnetic wheel to rotate.

[0023] By adopting the above technical solution, the one-way bearing reduces the friction between the active magnetic wheel and the housing, and at the same time makes the active magnetic wheel rotate only in one direction, thus making it more stable when the driven magnetic wheel drives the active magnetic wheel to rotate.

[0024] Optionally, a limiting sleeve is provided on the connecting seat, the limiting sleeve being used to keep the connecting screw and the connecting seat on the same axis; the fan blade includes a fixed ridge and a blade, the fixed ridge being fixedly connected to the driven magnetic wheel, and the blade being fixedly connected to the fixed ridge.

[0025] By adopting the above technical solution, the setting of the limiting cylinder allows the limiting cylinder to slide to the hinge point between the connecting screw and the connecting seat when the housing is installed, so that the connecting screw and the connecting seat are kept on the same axis, which facilitates the rotation of the connecting screw by fixing and driving it, thereby screwing the connecting screw into the preset mounting hole, thus achieving the effect of facilitating installation.

[0026] Optionally, a telescopic rod is coaxially inserted through the fixed edge.

[0027] By adopting the above technical solution, the extension rod increases the lever arm, making it easier to screw the connecting screw into the preset mounting hole when installing the connecting screw.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the housing, camera body, active magnetic wheel, temperature sensor, driven magnetic wheel, fan blades, and cleaning components, when the temperature sensor detects that the temperature of the camera body is too high, it will start the active magnetic wheel to rotate. During the rotation of the active magnetic wheel, it will drive the driven magnetic wheel to rotate. The rotation of the driven magnetic wheel will not only drive the fan blades to rotate, but also drive the cleaning components to clean the dust on the housing, thereby improving the airflow around the housing and enhancing the heat dissipation of the housing. 2. Through the cooperation of the driven magnetic wheel, the driving gear, the driven gear, the reciprocating ring and the cleaning rod, the driven magnetic wheel can drive the driving gear when it rotates, and at the same time the cleaning rod can reciprocate to clean the upper surface of the housing, thereby achieving the effect of facilitating the cleaning of dust on the upper surface of the housing; 3. The connection of the connecting seat, connecting screw, fixing rib, one-way bearing, and limiting sleeve facilitates the installation of the connecting screw in the preset mounting hole, thereby achieving the effect of facilitating the installation of the housing.

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses an explosion-proof monitoring enclosure.

[0035] Reference Figure 1 and Figure 2 An explosion-proof monitoring enclosure includes a housing 1, a heat dissipation assembly 2, and a cleaning assembly 3. A camera body 11, an active magnetic wheel 12, and a temperature sensor 13 are installed inside the housing 1. The camera 11 is located at one end inside the housing 1, and the active magnetic wheel 12 is rotatably connected to the other end of the housing 1, rotating about the length of the housing 1. The temperature sensor 13 is fixedly connected to the side near the camera body 11 to detect the temperature of the camera body 11. The heat dissipation assembly 2 is sleeved on the end of the housing 1 near the active magnetic wheel 12. The heat dissipation assembly 2 includes a driven magnetic wheel 21 and fan blades 22. The driven magnetic wheel 21 and the active magnetic wheel 12 are concentrically slidably sleeved on the housing 1, and fan blades 22 are arranged circumferentially on the driven magnetic wheel 21. The cleaning assembly 3 is installed on the outer surface of the housing 1. The cleaning assembly 3 includes a transmission component 31, one end of which is connected to the driven magnetic wheel 21, and the other end is connected to a cleaning rod 32, which is attached to the upper surface of the housing 1.

[0036] The camera body 11 includes a camera 111 and an illumination lamp 112 for supplementing light to the camera 111. The camera 111 and the illumination lamp 112 are located on the same side of the housing 1, so that the illumination lamp 112 can provide supplementary light to the camera 111.

[0037] In this application, the upper half of the active magnetic wheel 12 is N-stage and the lower half is S-stage, and the upper half of the driven magnetic wheel 21 is S-stage and the lower half is N-stage. In other embodiments, the N-stage and S-stage of the active magnetic wheel 12 or the driven magnetic wheel 21 may be distributed at intervals around its own axis, so that the active magnetic wheel 12 can drive the driven magnetic wheel 21 to rotate during rotation.

[0038] The fan blade 22 includes a fixed rib 221 and a blade 222. The fixed rib 221 is fixedly connected to the driven magnetic wheel 21, and the middle part of the blade 222 is fixedly connected to the fixed rib 221. The blade 222 has a certain tilt angle. The tilted blade 222 facilitates the flow of air near the housing 1.

[0039] Because the explosion-proof camera 111 is installed in a flammable and explosive environment, its housing 1 has excellent sealing performance. This reduces the risk of the circuit components inside the camera body 11 becoming a ignition source. Therefore, it is inconvenient to connect an external fan for heat dissipation when the explosion-proof camera 111 needs to dissipate heat. If the external fan motor is exposed outside the housing 1, the external motor can easily become a new ignition source. At the same time, dust easily accumulates on the upper surface of the housing 1. The accumulated dust affects the thermal conductivity of the housing 1, thereby reducing its heat dissipation performance.

[0040] Therefore, this application includes an active magnetic wheel 12 driven by a motor inside the housing 1. When the temperature sensor 13 detects that the camera body 11 is hot, the temperature sensor 13 starts the motor to drive the active magnetic wheel 12 to rotate. The rotation of the active magnetic wheel 12 drives the rotation of the driven magnetic wheel 21, which in turn drives the fan blade 22 to rotate. During the rotation of the fan blade 22, the air around the housing 1 can be circulated, thereby improving the heat dissipation effect of the housing 1. At the same time, during the rotation of the driven magnetic wheel 21, the transmission component 31 drives the cleaning rod 32 to move on the upper surface of the housing 1 to clean the dust on the upper surface of the housing 1.

[0041] Reference Figure 3 A limiting frame 4 is fixedly connected to the housing 1. In this application, the transmission component 31 includes a driving gear 311, a driven gear 312, and a reciprocating ring 313. The driving gear 311 is rotatably connected to the limiting frame 4. The driven magnetic wheel 21 has teeth, and the driving gear 311 meshes with the teeth on the driven magnetic wheel 21. The driven gear 312 is coaxially fixedly connected to the driving gear 311. The driven gear 312 is an incomplete gear. The reciprocating ring 313 is slidably installed inside the limiting frame 4, which restricts the reciprocating ring 313 from sliding along a length perpendicular to the housing 1. One end of the reciprocating ring 313 near the middle of the housing 1 is fixedly connected to a cleaning rod 32. The cleaning rod 32 extends out of the limiting frame 4 and abuts against the housing 1. A brush is provided on the side of the cleaning rod 32 that extends out of the limiting frame 4 and is close to the housing 1. The brush facilitates the cleaning rod 32 in cleaning the housing 1.

[0042] Reference Figure 2 A limiting seat 5 is provided at the end of the cleaning rod 32 away from the reciprocating ring 313. The limiting seat 5 is fixedly connected to the housing 1, and a shielding eave 51 extends from the side of the limiting seat 5 away from the housing 1. The limiting seat 5 reduces the possibility that the cleaning rod 32 may not make sufficient contact with the upper surface of the housing 1 due to the end of the cleaning rod 32 away from the reciprocating ring 313 being tilted up. At the same time, the shielding eave 51 reduces the possibility that dust may adhere to the camera lens on the camera body 111.

[0043] When the driven magnetic wheel 21 rotates, it drives the driving gear 311 to rotate. The rotation of the driving gear 311 drives the driven gear 312 to rotate. The rotation of the driven gear 312 drives the reciprocating ring 313 to reciprocate. The reciprocating motion of the reciprocating ring 313 drives the cleaning rod 32 to reciprocate. The reciprocating motion of the cleaning rod 32 cleans the dust on the upper surface of the housing 1.

[0044] A connecting part 6 is fixedly connected to the side of the housing 1 away from the camera body 11. Since the fan blade 22 needs to rotate, it is inconvenient to place the connecting part 6 on the side of the housing 1. The connecting part 6 in this application includes a connecting seat 61 and a connecting screw 62. In other embodiments, the connecting part 6 can also be directly set as a connecting bracket. The connecting screw 62 in this application is convenient to install in the preset mounting hole.

[0045] The connector 61 is fixedly connected to the housing 1. The connecting screw 62 is hinged to the connector 61, and a tightening bolt is provided at the hinge. By tightening the tightening bolt, the connector 61 and the connecting screw 62 are locked, thereby facilitating the adjustment of the angle of the camera 111.

[0046] A limiting sleeve 63 is slidably sleeved on the connecting seat 61. By sliding the limiting sleeve 63 to the hinge point between the connecting screw 62 and the connecting seat 61, the connecting screw 62 and the connecting seat 61 are kept on the same axis. When installing the housing 1, sliding the limiting sleeve 63 to the hinge point between the connecting screw 62 and the connecting seat 61 facilitates the rotation of the connecting screw 62, thereby screwing the connecting screw 62 into the preset mounting hole, thus facilitating installation.

[0047] After installation, slide the limiting cylinder 63 away from the hinge point towards the connecting seat 61, so that the connecting seat 61 and the connecting screw 62 can rotate freely. Then tighten the bolt to lock the connecting seat 61 and the connecting screw 62.

[0048] Auxiliary rings 7 are fixedly connected to the housing 1 and the connecting screw 62, respectively. A traction rope 71 is provided between the auxiliary rings 7, and the traction rope 71 passes through the two auxiliary rings 7. The auxiliary rings 7 limit the movement of the traction rope 71. By using the traction rope 71 to pass through the two auxiliary rings 7 and tightening the traction rope 71, a proper angle is maintained between the connecting seat 61 and the connecting screw 62, reducing the possibility of changes in the angle of the camera 111 due to unstable hinge.

[0049] A one-way bearing 8 is also provided between the driven magnetic wheel 21 and the housing 1. The one-way bearing 8 reduces the friction between the driving magnetic wheel 12 and the housing 1.

[0050] Meanwhile, the one-way bearing 8 restricts the driven magnetic wheel 21 to rotate only when the driving magnetic wheel 12 rotates in one direction. When the driven magnetic wheel 21 rotates in reverse, it is locked to the housing 1. Since the connecting screw 62 requires the housing 1 to rotate during installation, the housing 1 can be rotated by utilizing the cooperation between the fixing ridge 221 and the one-way bearing 8, thus facilitating the screw to be screwed into the preset mounting hole.

[0051] A telescopic rod 9 is coaxially mounted on the fixed ridge 221. The telescopic rod 9 can be stored inside the fixed ridge 221, and the fixed ridge 221 can be pulled out during use. When the telescopic rod 9 is pulled out during use, the increased lever arm of the telescopic rod 9 makes it easier to rotate the housing 1. When installing the connecting screw 62, extending the telescopic rod 9 makes it easier to screw the connecting screw 62 into the preset mounting hole.

[0052] The implementation principle of an explosion-proof monitoring enclosure according to an embodiment of this application is as follows: A mounting hole is made at a suitable position on the enclosure 1 where the camera 111 needs to be installed, and an expansion bolt is installed into the mounting hole. Then, the limiting cylinder 63 is slid to the hinge point between the connecting screw 62 and the connecting seat 61. Next, the connecting screw 62 is inserted into the expansion bolt, and the telescopic rod 9 is rotated to screw the connecting screw 62 into the expansion bolt. Then, the telescopic rod 9 is retracted into the fixing ridge 221. Next, the limiting cylinder 63 is slid away from the hinge point. Then, the angle of the camera 111 is adjusted. After adjusting to a suitable angle, the tightening bolt is tightened. Then, the traction rope 71 is threaded through the two auxiliary rings 7, so that the traction rope 71 is in a taut state, thereby completing the installation of the enclosure 1.

[0053] During use, when the temperature sensor 13 detects that the temperature of the camera body 11 is high, the temperature sensor 13 starts the motor to drive the active magnetic wheel 12 to rotate. The rotation of the active magnetic wheel 12 drives the rotation of the driven magnetic wheel 21, thereby causing the fan blade 22 to rotate and accelerate the airflow around the housing 1, so that the housing 1 has a good heat dissipation effect.

[0054] Simultaneously, as the driven magnetic wheel 21 rotates, it drives the driving gear 311 to rotate, which in turn drives the driven gear 312 to rotate. The driven gear 312 then drives the reciprocating ring 313 to reciprocate, which in turn drives the cleaning rod 32 to reciprocate. The reciprocating motion of the cleaning rod 32 cleans the dust on the upper surface of the housing 1. After the dust is cleaned, the top of the housing 1 has good thermal conductivity. In addition, the rapidly flowing air not only blows the dust down but also improves the heat dissipation effect.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
