[0002] Explosion-proof means that it can withstand the impact and heat of an explosion without suffering any damage and can still work normally. To prevent the occurrence of an explosion, three necessary conditions must be considered. If one of the necessary conditions is restricted, the occurrence of the explosion will be restricted. A double-sided camera terminal means that a surveillance camera can shoot in two different directions at the same time. Generally, two cameras in different directions are installed on one camera. This type of camera is usually used in scenes that need to monitor multiple directions at the same time, such as banks, shops, public transportation and other places.
[0003] However, in the prior art, since the cause of the explosion includes the factor of excessively high internal temperature of the body, and most cameras are installed outdoors or in other public places, when the external temperature reaches a certain level, the internal terminal will also generate high temperature when working. At this time, if the internal temperature is not controlled in time and the electronic components are damaged, the camera may explode, resulting in a fire hazard and posing a serious threat to public safety. Traditional heat dissipation technology cannot monitor the internal temperature to dissipate heat in a timely manner, and cannot shut down the heat dissipation components when heat dissipation is not needed, resulting in energy waste.

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] like Figure 1-4 As shown, the utility model provides a technical solution: an explosion-proof double-sided camera terminal, comprising a main housing 100, cameras 101 are fixedly installed on both sides of the main housing 100, protective baffles 102 for protecting the cameras 101 are fixedly connected to the outer walls of both sides of the main housing 100, heat dissipation ports 200 are symmetrically opened on the top wall of the main housing 100, a temperature sensor 103 is fixed on the inner side wall of the main housing 100, and heat dissipation components are arranged inside the heat dissipation ports 200;
[0021] The heat dissipation component includes a drive motor 201, which is fixedly installed on the inner side of the main shell 100 through a connecting plate. The output end of the drive motor 201 is fixedly connected to an active rotating rod 202. The outer wall of the active rotating rod 202 is sleeved with a fixing ring 203. The outer wall of the fixing ring 203 is symmetrically fixed with a fixing rod 204. One end of the fixing rod 204 is fixedly connected to the inner wall of the heat dissipation port 200. A plurality of fan blades 205 are fixed in an array on the outer wall of the active rotating rod 202. An auxiliary driving mechanism for driving the two active rotating rods 202 to rotate synchronously is provided at the end of the active rotating rod 202.
[0022] Specifically, when the temperature inside the main shell 100 rises to the alarm value, the temperature sensor 103 sends a signal to start the drive motor 201, so that the drive motor 201 drives the active rotating rod 202 to rotate, and the active rotating rod 202 drives the fan blades 205 to rotate, and the hot air inside is drawn out, thereby completing the effect of heat dissipation of the terminal inside the main shell 100. When the internal temperature drops, the temperature sensor 103 sends a signal to drive the motor 201. At this time, the fan blades 205 stop rotating, and no longer dissipate heat to the inside of the main shell 100, thereby keeping the temperature inside the main shell 100 always within a safe range, improving safety, and preventing the internal terminal from exploding due to high temperature. The fixing rod 204 is used to fix the fixing ring 203, and the fixing ring 203 is used to fix the active rotating rod 202.
[0023] As an implementation method in this embodiment, Figure 2 As shown, the auxiliary driving mechanism includes a rotating wheel 206 fixedly mounted on the outer wall of the end of the active rotating rod 202, and the two rotating wheels 206 are connected to the belt 207 for transmission. When the driving motor 201 drives the active rotating rod 202 to rotate, the active rotating rod 202 will drive one of the rotating wheels 206 to rotate. At this time, the belt 207 connected to the outside of the rotating wheel 206 is connected to drive the other rotating wheel 206 to rotate, and the rotating wheel 206 drives the other rotating rod to drive the fan blades 205 to rotate, thereby achieving a dual-purpose effect of one drive.
[0024] As an implementation method in this embodiment, Figure 4 As shown, a top cover 300 is symmetrically arranged on the top surface of the main shell 100, the heat dissipation port 200 is located on the inner side of the top cover 300, and filter holes 301 are arranged in an array on the top surface of the top cover 300. The top cover 300 is used to protect the fan blades 205 to prevent debris from damaging the fan blades 205. At the same time, the filter holes 301 can filter external impurities and dust to prevent them from entering the main shell 100 and damaging the electronic devices, thereby creating a safety hazard.
[0025] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the top of the active rotating rod 202 passes through the top of the top cover 300 and the outer wall is fixedly connected with a cleaning brush 209. The outer wall of the active rotating rod 202 is rotatably connected to the top cover 300 through a bearing. Due to the long-term use of the filter hole 301, the filter hole 301 will produce accumulated dust and impurities, and the camera is generally installed at a higher position, which is inconvenient to clean. Therefore, when the active rotating rod 202 rotates, it drives the cleaning brush 209 to move in a circular motion close to the top surface of the top cover 300, thereby cleaning the filter hole 301 of the top cover 300 and achieving a self-cleaning effect.
[0026] As an implementation method in this embodiment, Figure 2 As shown, a plurality of ventilation holes 104 are symmetrically opened on the bottom surface of the main shell 100, and the ventilation holes 104 are connected to the interior of the main shell 100, so that external air can flow into the interior of the main shell 100, so that the interior of the main shell 100 maintains a normal temperature, thereby improving the heat dissipation effect on the interior.
[0027] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the temperature sensor 103 and the drive motor 201 are both electrically connected to an external controller, and the external controller is preset with a standard temperature value. The temperature sensor 103 transmits the detected temperature value to the external controller via data in real time. When the temperature value detected by the temperature sensor 103 is greater than the preset temperature value, the external controller controls the start of the drive motor 201. When the temperature value detected by the temperature sensor 103 is less than the preset temperature value, the external controller controls the shutdown of the drive motor 201, thereby saving energy consumption.
[0028] Working principle: The external controller is preset with a standard temperature value, and the temperature sensor 103 will transmit the detected temperature value to the external controller in real time through data. When the temperature value detected by the temperature sensor 103 is greater than the preset temperature value, the external controller controls the start of the drive motor 201. When the temperature value detected by the temperature sensor 103 is less than the preset temperature value, the external controller controls the shutdown of the drive motor 201, and the drive motor 201 is started, so that the drive motor 201 drives the active rotating rod 202 to rotate, and the active rotating rod 202 will drive one of the rotating wheels 206 to rotate. At this time, the belt sleeved on the outer side of the rotating wheel 206 The transmission connection 207 drives another rotating wheel 206 to rotate, and the rotating wheel 206 drives another rotating rod to drive the fan blades 205 to rotate. The active rotating rod 202 drives the fan blades 205 to rotate, and the hot air inside is drawn out, so as to achieve the effect of heat dissipation of the terminal inside the main shell 100. When the active rotating rod 202 rotates, it drives the cleaning brush 209 to move in a circular motion close to the top surface of the top cover 300 to clean the filter hole 301 of the top cover 300. When the internal temperature drops, the temperature sensor 103 will drive the motor 201. At this time, the fan blades 205 stop rotating, and no longer dissipate heat to the inside of the main shell 100.
