Description

Technical Field

[0001] This utility model relates to the field of security camera technology, and in particular to a waterproof and dustproof industrial security camera. Background Technology

[0002] Industrial security cameras are high-performance monitoring devices specifically designed for industrial environments, featuring high resolution, high stability, and strong environmental adaptability. Their core functions include real-time monitoring, anomaly detection, and data logging, and they are widely used in factory perimeters, production lines, warehouses, and other scenarios. The devices utilize industrial-grade sensors such as CCD or CMOS, combined with intelligent analysis technology, to achieve intelligent human detection, enhanced night vision, and remote access. By integrating into factory security systems, industrial security cameras can trigger audible and visual alarms, video playback, and other functions, providing enterprises with 24 / 7 security and helping to improve production efficiency and management levels.

[0003] Existing industrial security cameras often have heat dissipation slots on their casings for heat dissipation. When industrial security cameras are used in humid environments for a long time, moisture enters the camera through the heat dissipation slots. The moisture may contain acidic, alkaline, or other corrosive substances. These substances can react chemically with the metal components inside the camera (such as copper foil on the circuit board, metal pins at the interface, etc.), causing corrosion of the component surfaces and increasing the risk of short circuits. To solve the above problems, we propose a waterproof and dustproof industrial security camera. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where moisture enters the camera through the heat dissipation channel, causing corrosion of the surface of the metal components inside the camera and increasing the risk of short circuits. Therefore, this invention proposes a waterproof and dustproof industrial security camera.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof and dustproof industrial security camera includes a housing with a camera installed inside. A bracket is fixedly mounted on the housing. Multiple heat dissipation slots are provided on both sides of the housing, and the housing communicates with the external space through the heat dissipation slots. Air intake covers are fixedly mounted on both sides of the housing. The heat dissipation slots are located inside the air intake covers. Two spaced-apart air inlets are provided at the lower end of the heat dissipation slots. A filter screen is provided inside the air intake cover, and the filter screen is slidably connected to the air intake cover on both the upper and lower sides. Two absorbent cotton blocks are inserted into the lower end of the air intake cover, and the absorbent cotton blocks are sealed above the air inlets and slidably mounted on the air intake cover.

[0007] Preferably, a power cord runs through the outer casing, and the power cord is electrically connected to the camera and used to supply power to the camera.

[0008] Preferably, the filter screen is a rigid mesh, and two symmetrically distributed support plates are fixedly installed inside the air intake hood. Springs are fixedly connected to both ends of the top of the filter screen, and the upper ends of the springs are fixedly connected to the support plates.

[0009] Preferably, a vertical rod is fixedly connected to the center of the bottom of the filter screen, the lower end of the vertical rod passes through the air intake hood and can slide up and down, a servo motor is fixedly installed on the air intake hood, and a cam is fixedly installed on the output shaft end of the servo motor, the cam being in contact with the vertical rod.

[0010] Preferably, the top of the outer shell has a through-hole that communicates with the inner cavity of the outer shell. A negative pressure fan is fixedly installed on the outer shell. The air inlet of the negative pressure fan is connected to the through-hole. The exhaust end of the negative pressure fan is connected to and fixedly installed with an exhaust pipe. The end of the exhaust pipe is set downwards, and a valve is installed on the exhaust pipe.

[0011] Preferably, the power cord is covered with a protective cover, one end of which is connected to the outer shell by screws, and a sealing ring is fixedly connected inside the protective cover, through which the power cord passes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] During operation, the camera generates heat. This heat is dissipated through heat dissipation channels and air intakes, maintaining the camera's normal operating temperature. When outside air enters the air intake housing through the air intake, absorbent pads and filters absorb moisture and remove dust. The absorbent pads absorb moisture from the air, preventing it from entering the housing through the air intake and heat dissipation channels, thus providing waterproofing. The filters also remove dust and other impurities from the air, preventing dust from entering the housing and affecting the camera's normal operation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Reference Figure 1-6 A waterproof and dustproof industrial security camera includes a housing 1, a camera 2 installed inside the housing 1, a bracket 4 fixedly installed on the housing 1, multiple heat dissipation slots 5 on both sides of the housing 1, the housing 1 communicating with the outside space through the heat dissipation slots 5, an air intake shroud 6 fixedly installed on both sides of the housing 1, the heat dissipation slots 5 being located inside the air intake shroud 6, two spaced air inlets 7 being opened at the lower end of the heat dissipation slots 5, a filter screen 8 being installed inside the air intake shroud 6, the filter screen 8 being slidably connected to the air intake shroud 6 on both the upper and lower sides, and two water-absorbing cotton blocks 9 being inserted into the lower end of the air intake shroud 6, the water-absorbing cotton blocks 9 sealing above the air inlets 7, and the water-absorbing cotton blocks 9 being slidably installed on the air intake shroud 6.

[0024] The outer casing 1 has a power cord 3 running through it. The power cord 3 is electrically connected to the camera 2 and is used to supply power to the camera 2. The power cord 3 is covered by a protective cover 18. One end of the protective cover 18 is connected to the outer casing 1 by a screw. A sealing ring 19 is fixedly connected inside the protective cover 18, and the power cord 3 passes through the sealing ring 19.

[0025] During operation, the camera 2 generates heat. The heat is connected to the outside space through the heat dissipation slot 5 and the air inlet 7 to dissipate the heat generated by the camera 2 and maintain the normal operating temperature of the camera 2.

[0026] When outside air enters the air intake cover 6 through the air intake 7, the absorbent cotton block 9 and the filter screen 8 absorb moisture and remove dust from the air. The absorbent cotton block 9 absorbs the moisture in the air, preventing moisture from entering the outer casing 1 through the air intake 7 and the heat dissipation groove 5, thus providing a waterproof function. The filter screen 8 also filters out dust and other impurities in the air, preventing dust from entering the outer casing 1 and affecting the normal operation of the camera 2.

[0027] The protective cover 18, together with the sealing ring 19, seals the connection between the power cord 3 and the outer shell 1. The sealing ring 19 can fit tightly against the power cord 3, thereby preventing external dust, moisture, etc. from entering the interior of the outer shell 1 through the connection between the power cord 3 and the outer shell 1, thus protecting the normal operation of the camera 2.

[0028] Based on Example 1, Example 2:

[0029] Reference Figure 2-6 The filter screen 8 is a rigid mesh. Two symmetrically distributed support plates 10 are fixedly installed inside the air intake shroud 6. Springs 11 are fixedly connected to both ends of the top of the filter screen 8, and the upper ends of the springs 11 are fixedly connected to the support plates 10. A vertical rod 12 is fixedly connected to the center of the bottom of the filter screen 8. The lower end of the vertical rod 12 passes through the air intake shroud 6 and can slide up and down. A servo motor 13 is fixedly installed on the air intake shroud 6. A cam 14 is fixedly installed on the output shaft end of the servo motor 13, and the cam 14 contacts the vertical rod 12.

[0030] After long-term filtration, dust will accumulate on the lower surface of the filter 8, causing it to become clogged. The servo motor 13 drives the cam 14 to rotate, which in turn drives the vertical rod 12 to move up and down. A spring 11 is used to reset the filter 8, which in turn moves the filter 8 up and down. This up-and-down movement causes the dust on the lower surface of the filter 8 to be vibrated and subjected to friction, thus shaking off the dust and achieving an automatic dust removal effect. This effectively prevents the filter 8 from becoming clogged, ensures that air can pass through the filter 8 smoothly, and maintains the good heat dissipation performance of the camera 2.

[0031] The outer shell 1 has a through-hole 15 at the top, which is connected to the inner cavity of the outer shell 1. A negative pressure fan 16 is fixedly installed on the outer shell 1. The air inlet of the negative pressure fan 16 is connected to the through-hole 15, and the exhaust end of the negative pressure fan 16 is connected to and fixedly installed with an exhaust pipe 17. The end of the exhaust pipe 17 is set downward, and a valve is installed on the exhaust pipe 17.

[0032] Open the valve on the exhaust pipe 17 and start the negative pressure fan 16. The negative pressure fan 16 draws in the high-temperature air from the inner cavity of the outer casing 1 through the through-hole 15. The high-temperature air is discharged through the exhaust pipe 17, reducing the air pressure inside the outer casing 1. Outside air enters the outer casing 1 through the air inlet 7 and the heat dissipation slot 5, balancing the internal air pressure and accelerating the airflow speed inside the outer casing 1. This active suction method is more efficient than relying solely on natural convection for heat dissipation, effectively reducing the temperature inside the outer casing 1 and preventing problems such as performance degradation, image quality deterioration, or even damage to the camera 2 due to overheating.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
