Description

Technical Field

[0001] The present invention relates to the field of cameras, and in particular, to a fireproof monitoring camera. Background Art

[0002] Inside a building, once a fire breaks out, firefighters need to have a certain understanding of the fire situation inside the building so that they can make an effective fire-fighting plan based on the fire situation inside the building. However, when a fire breaks out inside a building, it is generally very difficult for firefighters to directly obtain fire information, such as the ignition point, the location of the fire, the combustibles, the surrounding combustibles, the fire intensity, and the development and spread of the fire. More often, it is the oral description of the evacuated personnel, with low accuracy. At this time, firefighters need to risk their lives to enter the fire scene to obtain information, and then leave the fire scene to comprehensively analyze the fire information and make an effective fire-fighting plan. However, during this period, the fire will further develop, and there is a time difference between the information obtained and the real-time fire situation, and the information is lagging behind.

[0003] Currently, it is also possible to use the monitoring cameras inside the building to analyze and judge the fire situation. However, the current monitoring cameras have poor fireproof performance. The fire scene is a high-temperature environment, which will cause the current monitoring cameras to lose their functions in the high-temperature environment. There are a large number of molten floating particles formed after combustion in the fire scene, and these particles are extremely easy to adhere to the camera, causing the camera to lose its effective monitoring ability. Moreover, if the fire has burned the lines in the fire scene, the current cameras will also lose their monitoring ability.

[0004] In summary, it is necessary to develop a fireproof monitoring camera with power supply and signal self-sustaining capabilities and strong survivability in the fire scene to solve the above problems. Summary of the Invention

The outer circumference of the glass ring 83 is in sealed contact fit with the inner peripheral wall of the enclosing frame 2. When the first electric annular slide rail 81 is started, the moving parts of the first electric annular slide rail 81 will drive the rotating ring 82 and the glass ring 83 to rotate, so that the glass ring 83 rotates under the sealed enclosing state of the enclosing frame 2.

[0038] As Figure 4 , Figure 5 , Figure 6 , Figure 11 and 13 As shown, the monitoring device 9 includes a second electric annular slide rail 91 and a monitoring module 92.

An air pump 113 and a diode refrigeration module 114 are installed inside the temperature control box 111. When the air pump 113 and the diode refrigeration module 114 are started, the air pump 113 extracts air from inside the glass ring 83 through the front connecting pipe 112 and the lower compartment of the front steel pipe beam 5 and inputs it to the diode refrigeration module 114. After the air is cooled by the diode refrigeration module 114, it enters the glass ring 83 through the rear connecting pipe 112 and the lower compartment of the rear steel pipe beam 5, so as to cool the monitoring device 9 and the electric control device 10 inside the glass ring 83, enabling the monitoring device 9 and the electric control device 10 to maintain a normal working temperature when a fire occurs, increasing the monitoring time of the fire, and improving the self-sustaining ability of this fire-proof monitoring camera in the fire scene.

A brush disc 132 is fixedly connected between the output shafts of the driving motor 131. The brush disc 132 is a structure with hard brushes. When the driving motor 131 is started, the driving motor 131 drives the brush disc 132 to rotate, and thus the brush disc 132 scrubs the outer periphery of the glass ring 83.

The covering housing 142 and the assembly housing 141 jointly wrap around the fireproof monitoring camera and leave an open area on the left side of the surrounding frame 2. The injection pipe valve 143 is installed on the upper side of the covering housing 142. The refraction pipe valve is used to inject foaming flame retardant into the assembly housing 141 and the covering housing 142.

[0044] Embodiment 2, as Figures 1-18 As shown, the wiring method and installation method of this fireproof monitoring camera are as follows: ① Power supply wiring method: Pass the external ordinary power transmission line and emergency power transmission line into the glass ring 83 through the upper compartment structure of the steel pipe beam 5 and the bent steel pipe 6, connect the ordinary power transmission line and the emergency power transmission line to the electric control device 10, connect the battery module 102 to the electric control device 10 through a line, connect the electric control device 10 to the monitoring device 9 through a line, and then connect other electrical appliances of this fireproof monitoring camera to the electric control device 10 through a line, so that the electric control device 10 can switch the power supply from the ordinary power transmission line, the emergency power transmission line, and the battery module 102 for power supply. ② Video signal wiring method: Pass the external signal line into the glass ring 83 through the upper compartment structure of the steel pipe beam 5 and the bent steel pipe 6 and connect it to the electric control device 10, so that the electric control device 10 can transmit the video signal to the outside through its own long-wave signal generator and the external signal line. ③ Installation: After the wiring of this fireproof monitoring camera is completed, it can be installed on the wall through the wall hanging bracket 1.

[0045] The monitoring method of this fireproof monitoring camera: Turn on the normal light monitoring camera of the monitoring device 9 to monitor the environment and transmit the video signal through the external signal line. At this time, this fireproof monitoring camera is powered by the external ordinary power transmission line and charges the battery module 102; when a fire occurs, the thermal infrared monitoring camera of the monitoring device 9 can be turned on, and external personnel can judge the fire situation in the fire scene according to the thermal infrared monitoring camera of the monitoring device 9.

[0046] The self-sustaining solution for power supply and signal transmission of this fireproof monitoring camera when a fire occurs: When a fire breaks out: ① If the ordinary power transmission lines and signal lines in the outside world can normally carry out power transmission and signal transmission operations, the operation of this fireproof monitoring camera can be normally controlled. ② If the ordinary power transmission lines and signal lines in the outside world are affected by the fire and cannot normally carry out power transmission and signal transmission operations, the electronic control device 10 can switch to the emergency power transmission line in the outside world to supply power to this fireproof monitoring camera. The electronic control device 10 will also start its long-wave signal generator to transmit the video signal to the outside world. External personnel can still monitor the fire situation in the fire field without a signal line, which can reduce the dependence on the external signal line and monitor the fire situation through this fireproof monitoring camera itself, improving the self-sustaining ability of signal transmission. ③ If the emergency power transmission line in the outside world is also affected by the fire and cannot normally carry out power transmission and signal transmission operations, the electronic control device 10 can switch to the battery module 102 to supply power to this fireproof monitoring camera. At this time, the monitoring device 9 will switch to the low-power operation mode, so that the monitoring device 9 no longer conducts video monitoring but starts the photo-taking mode. The monitoring device 9 will take pictures of the fire field every 10 seconds. The electronic control device 10 will also start its long-wave signal generator to transmit the picture signal to the outside world. External personnel can still monitor the fire situation in the fire field according to the pictures and make timely and positive fire-fighting plans.

[0047] Through the connection of the electronic control device 10 with the battery module 102, the ordinary power transmission line, the emergency power transmission line and the signal line in the outside world, together with the current switch and long-wave signal generator of the electronic control device 10 itself, when a fire breaks out, even if the power supply and signal in the fire field have failed, this fireproof monitoring camera can still achieve self-sustaining power supply and signal transmission, improving the effective monitoring of this fireproof monitoring camera in the fire field, helping external personnel analyze and evaluate the fire situation in the fire field, and making timely and positive fire-fighting plans.

[0048] The survival self-sustaining plan of this fireproof monitoring camera when a fire breaks out: Ensure monitoring clarity: When a fire breaks out, the substances burned in the fire field will form floating particles containing various fusible substances, that is, black smoke. These black smokes are dispersed in the upper space of the environment by hot air. The black smoke will affect the glass ring 83, causing the fusible floating particles to adhere to the outer periphery of the glass ring 83. At this time, the first electric circular slide rail 81 and the water pump 123 can be turned on to make the glass ring 83 rotate within the enclosure 2. The spray pipe 122 will clean the rotating glass ring 83, so that the cleaned glass ring 83 is within the monitoring range of the monitoring device 9, enabling the monitoring device 9 to ensure the clarity of monitoring the fire situation in the fire field and avoid being affected by the floating particles containing various fusible substances formed by the substances burned in the fire field.

[0049] Guaranteed working temperature: When a fire occurs, a large amount of heat is released during the combustion process in the fire scene, forming a high-temperature environment. The high-temperature environment has an impact on the internal electrical appliances of this fire-proof monitoring camera, and it will cause the internal electrical appliances of this fire-proof monitoring camera to fail due to high temperature. At this time, the air pump 113 and the diode refrigeration module 114 can be turned on, so that the air pump 113 and the diode refrigeration module 114 cool the electrical appliances inside the glass ring 83, making the electrical appliances inside the glass ring 83 in a normal working temperature range. After the nozzle 122 sprays water to clean the glass ring 83, the liquid will remain inside the protective housing 4, cooling the electrical appliances inside the protective housing 4.

[0050] By installing the monitoring device 9 and the electronic control device 10 inside the glass ring 83, the first electric circular slide rail 81 drives the glass ring 83 to rotate, and with the cleaning of the glass ring 83 by the cleaning device 12, it can ensure the clarity of monitoring of this fire-proof monitoring camera in a fire scene with various molten floating particles, improving the effective monitoring ability of this fire-proof monitoring camera when a fire occurs. With the temperature control of the temperature control device 11, it can make this fire-proof monitoring camera still in a normal working temperature range in a high-temperature fire scene, further improving the self-sustaining ability of this fire-proof monitoring camera.
