[0022] Embodiment 1

[0023] like Figure 1 and Figure 2 As shown, a heating device for an outdoor hemispherical surveillance camera includes a protective shell 1 and a camera body 2, wherein the protective shell 1 is provided with a protective groove 3, the camera body 2 is located in the protective groove 3 and is connected to the protective shell 1 by mounting bolts, the upper end of the protective shell 1 is fixedly connected with a ventilation seat 4, the ventilation seat 4 is provided with a ventilation groove 5 communicating with the protective groove 3, the ventilation groove 5 is provided with a heat dissipation component, the protective groove 3 is provided with a heating component located in the camera body 2, the ventilation groove 5 is fixedly connected with a temperature sensor 6, the upper end of the ventilation seat 4 is symmetrically connected with an electric telescopic rod 7, the telescopic ends of the two electric telescopic rods 7 are fixedly connected with a blocking cover 8, one side of the protective shell 1 is connected with a wiring tube 17, and the external cable is electrically connected to the camera body 2 through the wiring tube 17.

[0024] Through the above structure, the external cable is electrically connected to the camera body 2 through the wiring tube 17, so that the camera body 2 can transmit the captured images, and the camera body 2 is fixedly connected to the protective housing 1 by installing bolts, so that the camera body 2 can work normally in the protective housing 1. The specific structures of its various components are as follows:

[0025] Combined with Figure 3 and Figure 4 As shown, the heating assembly includes a heater 9, a heat roller 10 and a heat-insulating cotton 11. The heater 9 is located at the upper end of the camera body 2 and is fixedly connected to the protective groove 3. The heat roller 10 is electrically connected to the output end of the heater 9. The heater 9 is electrically connected to the temperature sensor 6. The heat-insulating cotton 11 is fixedly connected to the inner wall of the protective groove 3.

[0026] Through the above structure, the heat roller 10 generates heat through the electrical connection with the heater 9, so that the temperature in the protection groove 3 increases, so that the main body part of the camera body 2 located in the protection groove 3 is heated, thereby ensuring that the camera body 2 can operate normally.

[0027] Combination Figure 3 and Figure 4 As shown, the heat dissipation assembly includes a support bar 12, a rotating motor 13, a rotating sleeve 14 and heat dissipation blades 15. The support bar 12 is fixedly inserted in the ventilation slot 5, and the rotating motor 13 is fixedly connected to the upper end of the support bar 12. The output end of the rotating motor 13 passes through the support bar 12 and is sleeved with the rotating sleeve 14. A plurality of heat dissipation blades 15 are fixed around the rotating sleeve 14, and the rotating motor 13 is electrically connected to the temperature sensor 6.

[0028] Through the above structure, when the temperature in the protective groove 3 is high, the rotating motor 13 drives the rotating sleeve 14 at the output end to rotate, and the heat dissipation blades 15 on the rotating sleeve 14 rotate along with the rotating sleeve 14, thereby dissipating the heat in the protective groove 3 from the ventilation groove 5 to the outside, thereby maintaining the temperature in the protective groove 3 stable.

[0029] Embodiment 2

[0030] Based on Example 1, please refer to the attached Figure 1 and attached Figure 2 The blocking cover 8 is a cone, a sealing cavity 16 is provided on the blocking cover 8, and the electric telescopic rod 7 is electrically connected to the temperature sensor 6.

[0031] Through the above structure of the second embodiment, the vertebral structure of the blocking cover 8 can shield the entire camera device in rainy and snowy weather. At the same time, when the weather is cold, the electric telescopic rod 7 drives the blocking cover 8 to descend, so that the sealed cavity 16 in the blocking cover 8 shields the ventilation slot 5, thereby maintaining the temperature in the protective slot 3.

[0032] The specific usage is as follows:

[0033] When the temperature in the protective groove 3 is low, the temperature sensor 6 in the protective groove 3 detects a low temperature signal and first feeds it back to the heater 9. The hot roller 10 generates heat through the electrical connection with the heater 9, thereby increasing the temperature in the protective groove 3, so that the main body part of the camera body 2 located in the protective groove 3 is heated, thereby ensuring that the camera body 2 can operate normally. At the same time, the temperature sensor 6 gives an electrical signal to the electric telescopic rod 7 on the ventilation seat 4, so that the electric telescopic rod 7 drives the cover 8 to descend, so that the sealed cavity 16 in the cover 8 blocks the ventilation groove 5, thereby maintaining the temperature in the protective groove 3.

[0034] When the temperature in the protection groove 3 is high, the temperature sensor 6 drives the electric telescopic rod 7 to rise, and at the same time starts the rotating motor 13, which drives the rotating sleeve 14 at the output end to rotate, and the heat dissipation blades 15 on the rotating sleeve 14 rotate with the rotating sleeve 14, so that the heat in the protection groove 3 is dissipated from the ventilation groove 5 to the outside, maintaining the temperature in the protection groove 3 stable.
