Abstract
Description
Technical Field
[0001] This utility model relates to astronomical image acquisition equipment. Background Technology
[0002] Fireball monitoring cameras, used to monitor astronomical phenomena such as fireballs, are typically housed in a casing that is fixed to a high pole outdoors. The top of the casing has a light-transmitting cover, and the lens of the fireball monitoring camera faces the light-transmitting cover to capture and record astronomical images.
[0003] Currently, the housings used in Huoliuxing surveillance cameras are not specifically designed for Huoliuxing cameras; they are usually modified from the housings of ordinary surveillance cameras sold on the market. Since the housings used in Huoliuxing surveillance cameras need to operate in outdoor environments exposed to sun and rain for extended periods, these modified housings lack dedicated waterproofing and heat dissipation designs, resulting in poor waterproofing and heat dissipation performance, which in turn affects the lifespan of the Huoliuxing surveillance cameras. Furthermore, the existing modified housings are inconvenient for disassembling and assembling Huoliuxing surveillance cameras. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a fire meteor monitoring camera assembly that ensures good heat dissipation while also having reliable waterproof performance.
[0005] Another technical problem to be solved by this utility model is to provide a fireball monitoring camera assembly that is easy to manufacture and assemble.
[0006] This utility model embodiment provides a Fire Meteor surveillance camera assembly, including a Fire Meteor surveillance camera and a housing. The housing includes a light-transmitting cover and a housing body. The light-transmitting cover is disposed on the top of the housing body and together with the housing body defines an inner cavity. The Fire Meteor surveillance camera is disposed in the inner cavity. The housing body includes a bottom wall, side walls, and a partition. The bottom of the side wall is connected to the periphery of the bottom wall, and a waterproof structure is provided between the top of the side wall and the light-transmitting cover. The periphery of the partition is connected to the inner surface of the side wall, and the partition has a camera mounting hole and multiple ventilation holes.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0017] Please see Figures 1 to 4 The fire meteor monitoring camera assembly according to the first embodiment of the present utility model includes a fire meteor monitoring camera 1, a housing 2, an exhaust fan 3, a temperature sensor 4, and a controller 5.
[0018] The outer shell 2 includes a light-transmitting cover 2a and a shell body 2b. The light-transmitting cover 2a is placed on top of the shell body 2b and together with the shell body 2b defines an inner cavity 20. The fire meteor monitoring camera 1, the suction fan 3, the temperature sensor 4 and the controller 5 are respectively disposed in the inner cavity 20.
[0019] The housing body 2b includes a bottom wall 21, a side wall 22, and a partition 23. The bottom of the side wall 22 is connected to the periphery of the bottom wall 21, and a waterproof structure is provided between the top of the side wall 22 and the light-transmitting cover 2a. In this embodiment, the waterproof structure includes a sealing ring (not shown in the figure). The top surface of the side wall 22 of the housing body is provided with an annular groove 220, and the sealing ring is placed in the annular groove 220. The outer shell 2 also includes a pressure ring 2c, which includes a threaded ring 241 and a pressure ring portion 242. The inner wall of the threaded ring 241 is provided with an internal thread 2411, and the periphery of the pressure ring portion 242 is connected to the top of the threaded ring 241. The top of the side wall 22 of the housing body is provided with an external thread 221 that matches the internal thread 2411 of the threaded ring 241.

[0020] The periphery of the partition 23 is connected to the inner surface of the side wall 22. The partition 23 has a camera mounting hole 231 and multiple ventilation holes 232. The Fire Meteor monitoring camera 1 passes through the camera mounting hole 231 and is fixed to the partition 23. In this embodiment, the side of the Fire Meteor monitoring camera 1 is provided with an annular protrusion 13, which presses against the upper surface of the partition 23 and is bonded to the upper surface of the partition 23. In another embodiment, the Fire Meteor monitoring camera 1 is also fitted with a limiting ring, which includes a limiting ring body and a screw. The limiting ring body is provided with a screw hole, and the screw is screwed into the screw hole and abuts against the side of the Fire Meteor monitoring camera 1 to fix the limiting ring body to the Fire Meteor monitoring camera 1. The limiting ring body abuts against the lower surface of the partition 23, thereby preventing the Fire Meteor monitoring camera 1 from moving upward. At the same time, this fixing structure also facilitates the assembly and disassembly of the Fire Meteor monitoring camera 1.
[0021] The bottom wall 21 has an air inlet 211 and an air outlet 212. Next to the air inlet 211, the bottom wall 21 also has an upwardly extending fan mounting base 28. Preferably, the height of the fan mounting base 28 (the distance between the upper surface of the fan mounting base 28 and the upper surface of the bottom wall 21) is 1.5cm to 2.5cm. The suction fan 3 is located below the partition 23 and is fixed to the fan mounting base 28. The connection between the suction fan 3 and the fan mounting base 28 includes, but is not limited to, bolt connection. The suction fan 3 faces the air inlet 211.
[0022] Preferably, a guide portion 213 is provided around the air outlet 212 to guide water accumulated on the bottom wall 21 into the air outlet 212. In this embodiment, the guide portion 213 is an inverted conical surface provided at the opening of the air outlet 212.
[0023] Preferably, the fire meteor monitoring camera assembly of this embodiment further includes a first dustproof net and a second dustproof net (not shown in the figure). The first dustproof net is fixed to the lower surface of the bottom wall 21 and covers the air outlet 212. The fixing method includes, but is not limited to, adhesive bonding. The second dustproof net is disposed between the fan positioning seat 28 and the suction fan 3 and covers the air inlet 211.
[0024] The signal output terminal of temperature sensor 4 is connected to the input terminal of controller 5, and the control output terminal of controller 5 is connected to the control terminal of suction fan 3 to control the operation of suction fan 3. Controller 5 can be, for example, a microcontroller.
[0025] In this embodiment, the housing body 2b includes an upper housing 201b and a lower housing 202b. Both the upper housing 201b and the lower housing 202b include annular sidewalls. The top of the annular sidewall 204b of the lower housing 202b is provided with an external thread 206b, and the bottom of the annular sidewall 203b of the upper housing 201b is provided with an internal thread 205b that mates with the external thread 206b. The bottom of the upper housing 201b and the top of the lower housing 202b are spirally connected. The periphery of the partition 23 is connected to the inner surface of the annular sidewall 203b of the upper housing 201b, and the periphery of the bottom wall 21 is connected to the bottom of the annular sidewall 204b of the lower housing 202b. The annular sidewalls 203b of the upper housing 201b and 204b of the lower housing 202b together constitute the sidewall 22 of the outer shell 2.
[0026] In this embodiment, the light-transmitting cover 2a is made of acrylic, while the upper shell 201b and lower shell 202b are both made of ASA resin, and both are manufactured using 3D printing. ASA resin is a ternary polymer composed of acrylonitrile, styrene, and acrylate rubber. It is an impact-modified resin with good weather resistance, high-temperature resistance, and antistatic properties. For monitoring housings that need to be exposed to outdoor environments for extended periods, ASA resin is lighter, more sun-resistant, and more corrosion-resistant than traditional metal housings. Manufacturing the housing using 3D printing allows for the printing of more complex structures, such as internal ventilation holes, fan mounting bases, and internal and external threads, all integrally formed, thus simplifying the manufacturing process.
[0027] In practical applications, the outer casing 2 is fixed to a high pole outdoors, exposed to sun and rain. When the temperature sensor 4 detects that the ambient temperature inside the outer casing 2 is greater than or equal to a preset temperature threshold (e.g., 35°C), the controller 5 controls the suction fan 3 to start working, thereby accelerating the air circulation inside the outer casing 2 and achieving the purpose of cooling. The suction fan 3 is set on the bottom wall 21 of the outer casing 2 and raised by the fan positioning seat 28 by about 2 cm, which can prevent the suction fan 3 from sucking rainwater into the inner cavity of the outer casing 2, achieving a good waterproof effect. In addition, a guide part 213 is provided around the water outlet 212 to guide the water accumulated on the bottom wall 21 into the air outlet 212, which can prevent water from accumulating inside the outer casing 2. A first dustproof net covering the air outlet 212 is affixed to the lower surface of the bottom wall 21, and a second dustproof net covering the air inlet 211 is affixed to the fan positioning seat 28, which can effectively prevent dust from entering the interior of the outer casing 2.
[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
