[0002] Surveillance cameras are quasi-cameras used in security. Their pixels and resolution are higher than those of computer video heads, but lower than those of professional digital cameras. Surveillance cameras can be divided into color cameras and black-and-white cameras according to imaging colors. They are mainly divided into gun-type, hemispherical, and high-speed ball types in appearance. There is also a distinction between analog monitoring and IP network monitoring. Surveillance cameras are widely used in many security fields such as banks, transportation, and safe cities. Among them, waterproof surveillance cameras are needed when outdoors.

[0003] Although waterproof surveillance cameras used outdoors have good waterproof performance, since they are used outdoors, the impact of bad weather such as rain and snow on the head of the surveillance camera must be considered. Rain or snow accumulation will cause unclear surveillance images, affecting normal use, and manual cleaning is cumbersome, time-consuming and laborious. To this end, we designed an external protection device for waterproof surveillance cameras to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof monitoring camera external protection device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

A motor is arranged outside the outer shell. The output shaft of the motor passes through the L-shaped gas pipeline and is connected to one end of the rotating shaft.

[0008] As a preferred solution of the utility model: the connection between the outer shell and the bottom cover is detachably connected by fixings, two groups of fixings are provided, and are symmetrically distributed in front and back of the circular through hole, the fixings include an upper fixing plate connected to the outer shell and a lower fixing plate connected to the bottom cover, and the upper fixing plate and the lower fixing plate are connected by bolts.

[0009] As a further preferred solution of the utility model: a notch is provided at the right end of the top wall inside the through opening, and the bottom of the sealing plate is embedded in the notch.

[0010] As a further preferred solution of the utility model: the air outlet nozzle is arranged obliquely, and its air outlet end faces the protective glass.

[0012] As a further preferred solution of the utility model: when the sealing plate is rotated to a horizontal state, the sealing plate closes the L-shaped gas transmission pipeline.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: in the device, when the sealing plate is rotated to a vertical state, the sealing plate can close the heat dissipation port, at this time the fan is controlled to rotate forward to blow air, the gas can only be transported to the heating chamber along the L-shaped gas pipeline, and when passing through the heating wire mesh inside the heating chamber, the gas is heated, and then the hot gas passes through the gas storage box and is ejected from a plurality of gas outlets and sprayed to the outer surface of the protective glass, the hot gas can quickly melt the snow on the surface of the protective glass or accelerate the evaporation of rainwater on the surface of the protective glass, thereby ensuring the cleanliness of the surface of the protective glass, and is suitable for rainy and snowy weather. The cleaning operation is simple and convenient, with a high degree of automation, saving time and effort. When the sealing plate is rotated to a horizontal state, the sealing plate can close the L-shaped air pipeline. At this time, the fan is controlled to reverse and exhaust air. Since the L-shaped air pipeline is closed, the fan can exhaust the hot air inside the outer shell, thereby reducing the internal temperature of the outer shell. That is, when the temperature rises during the operation of the camera and heat is generated inside the outer shell, the fan plays a role in heat dissipation, thereby increasing the service life of the device. Therefore, the device is a multifunctional device that integrates heat dissipation, rainwater removal, snow removal and waterproofing. It has high applicability and practicality and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

The air storage box 7 is located at the bottom of the rain shield 6. An L-shaped air pipeline 10 is provided in the auxiliary shell 11. The right end of the L-shaped air pipeline 10 is connected to a heating bin 8. A heating screen 9 is provided in the heating bin 8. The heating bin 8 is communicated with the inside of the air storage box 7. A plurality of air outlet nozzles 5 are provided at equal intervals along the length direction of the bottom of the air storage box 7. A heat dissipation port 17 is provided on the left side wall of the outer shell 1. The heat dissipation port 17 is communicated with the inside of the L-shaped air pipeline 10. A through hole 14 aligned with the position of the heat dissipation port 17 is provided on the left outer wall of the auxiliary shell 11, and a fan 15 is provided in the through hole 14.

[0021] A sealing plate 16 is rotatably connected to the L-shaped gas pipeline 10 via a rotating shaft. The sealing plate 16 is located on the left side of the heat dissipation port 17. A motor is provided outside the housing 1. The output shaft of the motor passes through the L-shaped gas pipeline 10 and is connected to one end of the rotating shaft. When the motor is started, the sealing plate 16 can be controlled to rotate through the rotating shaft.

[0022] A notch 13 is provided at the right end of the top wall of the opening 14, into which the bottom of the sealing plate 16 is embedded. This design allows the sealing plate 16 to just close the L-shaped gas pipeline 10 when it is rotated to a horizontal state. The structure is simple and the design is ingenious, ensuring the feasibility of the coordination between the structures.

[0023] like Figure 3 As shown, when the sealing plate 16 is rotated to a vertical state, the sealing plate 16 can close the heat dissipation port 17. At this time, the fan 15 is controlled to rotate forward to blow air, and the gas can only be transported to the heating chamber 8 along the L-shaped gas pipeline 10. When passing through the heating wire mesh 9 inside the heating chamber 8, the gas is heated, and then the hot gas passes through the gas storage box 7 and is sprayed out by a plurality of gas outlet nozzles 5, and sprayed to the outer surface of the protective glass 4. The hot gas can quickly melt the snow on the surface of the protective glass 4 or accelerate the evaporation of rainwater on the surface of the protective glass 4, thereby ensuring the cleanliness of the surface of the protective glass 4. It is suitable for rainy and snowy weather, and the cleaning operation is simple and convenient, with a high degree of automation, saving time and effort; as shown in FIG. Figure 4 As shown, when the sealing plate 16 is rotated to a horizontal state, the sealing plate 16 can close the L-shaped air pipeline 10. At this time, the fan 15 is controlled to reverse and exhaust air. Since the L-shaped air pipeline 10 is closed, the fan 15 can discharge the hot air inside the outer shell 1, thereby reducing the internal temperature of the outer shell 1. That is, when the temperature rises during the operation of the camera and heat is generated inside the outer shell 1, the fan 15 plays a role in heat dissipation, thereby increasing the service life of the device.

[0024] The connection between the outer shell 1 and the bottom cover 2 is detachably connected by a fixing piece. Two groups of fixing pieces are provided and are symmetrically distributed in front and behind the circular through hole 20. The fixing pieces include an upper fixing plate 12 connected to the outer shell 1 and a lower fixing plate 18 connected to the bottom cover 2. The upper fixing plate 12 and the lower fixing plate 18 are connected by bolts 19. The setting of the fixing piece makes it convenient to put the device on the outside of the camera and fix it.

[0025] The air outlet nozzle 5 is arranged at an angle, and its air outlet end faces the protective glass 4 ; this design facilitates the gas ejected from the air outlet nozzle 5 to fully contact the outer surface of the protective glass 4 , thereby improving practicality.
