[0028] Example:

[0029] Reference Figure 1-Figure 4 A protective device for a household fire warning camera includes a protective cover 1 and a protective shell 7, and also includes: an annular groove 8 opened in the protective cover 1, a cleaning and cooling mechanism 9 is arranged in the annular groove 8, and the cleaning and cooling mechanism 9 can reciprocate along the surface of the protective shell 7; a contact switch 10 arranged on the cleaning and cooling mechanism 9, a bimetallic strip 11 is fixedly connected to the inner wall of the annular groove 8, and the bimetallic strip 11 is made of two metal materials with different thermal expansion coefficients. When the temperature reaches a certain amount, the bimetallic strip 11 bends toward the side of the contact switch 10. The material of the bimetallic strip 11 is not limited here. As long as the bending degree of one metal is greater than the bending degree of the other metal when the temperature reaches a certain amount, the bimetallic strip 11 bends toward the side of the contact switch 10, such as the combination of metal copper and zinc or metal aluminum and iron, the bimetallic strip 11 fits the contact switch 10, and the contact switch 10 is electrically connected to the cleaning and cooling mechanism 9. The protective cover 1 is also fixedly connected with a mounting member 2, and the protective cover 1 can be mounted at a specified position through the mounting member 2 to achieve a better monitoring effect.

[0030] Reference Figure 1 and Figure 3 The cleaning and cooling mechanism 9 includes two sets of driving gears 91 rotatably connected in the annular groove 8, a driving device connected to the driving gear 91 is arranged in the annular groove 8, and two sets of driven gears 92 are rotatably connected inside the annular groove 8. The driven gear 92 is meshed with the driving gear 91, and the driving device of the driving gear 91 can also be controlled by the driving seat 5, so that residents can clean the protective shell 7 in time when they find that the picture monitored by the camera body 6 is not clear.

[0031] Reference Figure 3The cleaning and cooling mechanism 9 also includes a liquid storage ring 93 fixedly connected to the shafts of the two sets of driven gears 92. The liquid storage ring 93 is provided with multiple sets of nozzles 94. The inner wall of the liquid storage ring 93 is fixedly connected with a cleaning sheet 95. It should be explained that the cleaning sheet 95 is made of a material with a certain elasticity. When the cleaning sheet 95 rotates into the annular groove 8, it will bend to a certain extent so that it can be received in the annular groove 8. After the cleaning sheet 95 rotates out of the annular groove 8, it will extend, thereby contacting the surface of the protective shell 7, so as to achieve the effect of cleaning the surface of the protective shell 7.

[0032] Reference Figure 2 and Figure 4 A fixing ring 96 is fixedly connected to the inner wall of the annular groove 8, and two sets of direction control switches 97 are fixedly connected to the side of the fixing ring 96 close to the liquid storage ring 93. The direction control switch 97 is electrically connected to the driving device of the driving gear 91. When the liquid storage ring 93 rotates to contact with one of the direction control switches 97, the direction control switch 97 drives the liquid storage ring 93 to rotate in the opposite direction through the driving device of the driving gear 91. The specific structure of the direction control switch 97 can refer to the technical scheme in the prior art. Those skilled in the art can know it and will not be elaborated here.

[0034] Reference Figure 1-Figure 2 A mounting groove 4 is provided inside the protective cover 1, and a driving seat 5 is fixedly connected inside the mounting groove 4. A camera body 6 is rotatably connected to the driving seat 5, and the camera body 6 at least partially extends to the outside of the driving seat 5. A protective shell 7 is fixedly connected to the driving seat 5, and the protective shell 7 is sleeved on the outside of the camera body 6. The protective shell 7 is made of tempered glass material. It needs to be explained that the driving seat 5 is provided with equipment necessary for the operation of the camera body 6, such as a camera pan / tilt, a decoder, an infrared lamp, a data transmission device, an early warning device, etc.

[0035] In the utility model, when working, the protective cover 1 is installed at a specified position through the mounting member 2, and the environment within a certain range can be monitored through the camera body 6. At the same time, the camera body 6 can rotate in the driving seat 5 to increase the monitoring range of the camera body 6. When the surface of the protective shell 7 is contaminated with a lot of dust, residents can control the driving device of the driving gear 91 through the terminal (mobile phone, etc.), and drive the liquid storage ring 93 to rotate along the surface of the protective shell 7 through the driven gear 92. At the same time, water is sprayed to the surface of the protective shell 7 through the nozzle 94, so that the dust on the surface of the protective shell 7 is cleaned more thoroughly; and when a fire occurs, the temperature around the camera body 6 will rise, The bimetallic strip 11 will bend, and when the temperature reaches a certain level, the bimetallic strip 11 will trigger the contact switch 10, and the driving device of the driving gear 91 and the water pump in the water tank 3 will start, wherein the driving gear 91 drives the liquid storage ring 93 to rotate along the surface of the protective shell 7, and when the liquid storage ring 93 contacts the direction control switch 97 in the other direction, the driving gear 91 will rotate in the opposite direction, thereby driving the liquid storage ring 93 to reciprocate on the surface of the protective shell 7, and at the same time, water is sprayed to the surroundings and the surface of the protective shell 7 through the nozzle 94 to reduce the stability of the working environment of the camera body 6, and at the same time, the cleaning sheet 95 can clean the water stains on the surface of the protective shell 7 to ensure the monitoring effect of the camera body 6.
