[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the utility model proposes a built-in fire monitoring meter box, including a box body 1, an electric meter 2 and a control box 3. The electric meter 2 and the control box 3 are both located in the box body 1. The control box 3 is provided with a controller, a timer, a data receiver and other prior art devices, and the controller is electrically connected to the timer and the data receiver. For details, see the patent document with publication number CN206773041 U, which will not be described in detail here.

[0034] In addition, a glass sealing cover 23 is provided on the outside of the electricity meter 2, and the glass sealing cover 23 is fixed in the box body 1 by bolts. The glass sealing cover 23 can effectively protect the electricity meter 2 and prevent the electricity meter 2 from accumulating excessive dust.

[0035] like Figure 1-3As shown, the device also includes a fixed tank 4 fixedly installed inside the box body 1, and a carbon dioxide storage tank 5 and a dry powder storage tank 6 are arranged in the fixed tank 4. The output pipes of the carbon dioxide storage tank 5 and the dry powder storage tank 6 are connected to a solenoid valve 9. The two solenoid valves 9 are respectively provided with a control cable 24 connected to the control box 3. The control box 3 is electrically connected to the smoke sensor 7 and the carbon dioxide concentration sensor 8.

[0036] It is worth noting that the smoke sensor 7 is connected to the solenoid valve 9 of the corresponding dry powder storage tank 6, and the carbon dioxide concentration sensor 8 is connected to the solenoid valve 9 of the corresponding carbon dioxide storage tank 5. The smoke sensor 7 and the carbon dioxide concentration sensor 8 are both existing technologies, and the model of the carbon dioxide concentration sensor 8 is TGS4160;

[0037] In addition, it also includes a telescopic hose 17 connected to the bottom of the solenoid valve 9 corresponding to the carbon dioxide storage tank 5. The dry powder storage tank 6 is fixedly connected to the bottom of the solenoid valve 9 through a pipeline. When smoke is generated, the smoke sensor 7 receives the smoke signal and transmits the signal to the controller in the control box 3. After receiving and processing the signal, the controller controls the solenoid valve 9 to open, so that the dry powder fire extinguishing agent in the dry powder storage tank 6 is sprayed from the nozzle 10, which can quickly and promptly extinguish the fire;

[0038] It is worth mentioning that when the carbon dioxide concentration sensor 8 in the box body 1 detects that the carbon dioxide concentration is low, the signal is transmitted to the controller in the control box 3. After receiving and processing the signal, the controller controls the solenoid valve 9 to open, so that the carbon dioxide in the carbon dioxide storage tank 5 is sprayed out from the telescopic hose 17, and the carbon dioxide is replenished in time, so that the oxygen concentration in the box body 1 is at a low state, so that the combustion conditions inside are not available, and the occurrence of fire can be avoided as much as possible.

[0039] like Figure 2-4 As shown, the device also includes an intensification device, which is arranged at the bottom of the fixed groove 4 and is used to accelerate the speed of carbon dioxide ejection. The intensification device includes a fixed rod 19 fixedly installed at the bottom of the fixed groove 4. The bottom end of the fixed rod 19 is fixedly connected to an isolation frame 18 covering the outer wall of the output pipe of the carbon dioxide storage tank 5. A heating ring 22 is arranged in the isolation frame 18. The isolation frame 18 is cylindrical, and a corner of one side of the cylinder is cut off so that one side is in an empty state to avoid the risk of overheating of the output pipe due to the heating ring 22, thereby preventing the risk of explosion.

[0040] Furthermore, a moving block 21 is slidably installed on one side of the isolation frame 18, and the heating ring 22 is fixedly connected to the moving block 21. An electric telescopic rod 20 is fixedly installed on the bottom of the fixed groove 4, and one end of the electric telescopic rod 20 is fixedly connected to the moving block 21. The extension and contraction of the electric telescopic rod 20 drives the moving block 21 to move up and down, so that the heating ring 22 can move up and down in the isolation frame 18, so that the heating of the heating ring 22 is more uniform and the effect is better, thereby making the thermal motion of the carbon dioxide molecules intense and the collisions frequent, increasing the kinetic energy of the molecules, and making the carbon dioxide ejection speed faster and the effect more obvious.

[0041] like Figure 2-5 The device further includes an auxiliary mechanism, which is arranged on the inner wall of the box body 1 for expanding the range of carbon dioxide spraying. The auxiliary mechanism includes a slide 11 fixedly mounted on the inner wall of the box body 1, a slider 12 slidably mounted in the slide 11, a support rod 14 fixedly mounted on the slider 12, and a clamping member 15 for clamping a telescopic hose 17 is provided on the support rod 14. The clamping member 15 can clamp the telescopic hose 17 and move it up and down;

[0042] Furthermore, a reciprocating screw 13 threadedly connected to the slider 12 is rotatably installed in the slide 11, and a micro motor 16 is fixedly installed on the top of the slide 11. The output shaft of the micro motor 16 is fixedly connected to the reciprocating screw 13. When the micro motor 16 is started, the reciprocating screw 13 rotates, and the slider 12 drives the telescopic hose 17 to move back and forth along the direction of the slide 11, thereby expanding the spray range of carbon dioxide and improving the efficiency of replenishing the carbon dioxide concentration.

[0043] Working principle: When the carbon dioxide concentration sensor 8 in the box body 1 detects a low carbon dioxide concentration, the signal is transmitted to the controller in the control box 3. After receiving and processing the signal, the controller controls the solenoid valve 9 to open, so that the carbon dioxide in the carbon dioxide storage tank 5 is ejected from the telescopic hose 17, and the carbon dioxide is replenished in time, so that the oxygen concentration in the box body 1 is at a low state, so that the internal combustion conditions are not available, and the occurrence of fire can be avoided as much as possible. The extension and contraction of the electric telescopic rod 20 drives the movement of the moving block 21, so that the moving block 21 can drive the heating ring 22 to move up and down, so that the heating ring 22 heats the output pipe of the carbon dioxide storage tank 5 more evenly and the effect is better, thereby making the thermal motion of the carbon dioxide molecules intense and the collisions frequent, increasing the kinetic energy of the molecules, making the carbon dioxide ejection speed faster and the effect more obvious, starting the micro motor 16, so that the reciprocating screw 13 rotates, and the slider 12 drives the clamping part 15 to move up and down along the direction of the slide groove 11, so that the telescopic hose 17 moves and adjusts, expands the range of carbon dioxide ejection, and improves the efficiency of replenishing carbon dioxide concentration.

[0044] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
