[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0052] Example

[0053] like Figure 1-5 As shown, a fireproof distribution box based on intelligent control includes: a box body 1, an installation space with an opening at one end is arranged in the box body 1; a cover 5, the cover 5 is rotatably connected to the box body 1; a plurality of temperature sensors 2, the plurality of temperature sensors 2 are arranged at intervals in the installation space; a plurality of first smoke sensors 3, the plurality of first smoke sensors 3 are arranged at intervals in the installation space; a controller, the controller is electrically connected to the temperature sensor 2, and the controller is electrically connected to the first smoke sensor 3.

[0054] Specifically, the distribution box is used to accommodate a series of electrical components and is electrically connected to the transformer to distribute low-voltage electricity to several low-voltage users. The box body 1 is a rectangular box with an opening on one side, which encloses an installation space with an opening on one end. The electrical components are installed on the box body 1 and are located inside the installation space. The cover 5 is used to close the installation space. Multiple temperature sensors 2 are used to detect the temperature of multiple points in the installation space and transmit the signal to the controller. The first smoke sensor 3 is used to detect the smoke concentration signal of multiple points in the installation space and transmit it to the controller. The controller determines whether there is a fire hazard based on the temperature signal and the smoke concentration signal, and sends a fire alarm signal when it is determined that there is a fire hazard. Preferably, a buzzer and a transmitter are also provided in the distribution box. When the controller sends a fire alarm signal, the buzzer sends a buzzer alarm, and the transmitter sends a corresponding signal to notify the relevant staff to promptly remove the fire hazard, improve the safety performance of the distribution box, and avoid major safety accidents such as fire.

[0055] In detail, the controller is a CPU or a single-chip microcomputer. The method for the controller to send out a fire alarm signal is: detect temperature signals at multiple points in the installation space, obtain n temperature signals, obtain the maximum temperature according to the n temperature signals, and send out a fire alarm signal when the average temperature is obtained according to the n temperature signals, and calculate the root mean square of the n temperature signals in the installation space. The root mean square calculation formula is as follows:

[0056]

[0057] Where, T i is the temperature at a point in the installation space, is the average temperature, n is the total number of data; when it is determined that there is no fire hazard in the installation space, a fire alarm signal is issued. The fire hazard is judged by the root mean square, so as to avoid the issuance of a fire alarm signal when there is data abnormality at a single point, and improve the accuracy of the issued fire alarm signal. Specifically, when there is abnormal heating due to an electrical failure at a certain point in the installation space, which leads to a fire hazard, the temperature of the temperature sensor 2 at this point and around this point will be significantly higher than the temperature at other places, and will not be limited to one point. The root mean square can effectively eliminate the influence of single-point temperature abnormality on the judgment of fire hazard, and improve the accuracy of judgment. The root mean square error can effectively discover fire hazards and avoid the temperature rising to 150 and above, which makes it difficult to curb fire hazards in time. The specific root mean square threshold can be selected according to the actual situation. The type of the first smoke sensor 3 can be selected according to the actual situation. An ionization sensor, an optical fiber sensor and a thermal sensor can be selected. Taking the optical fiber first smoke sensor 3 as an example, when the shading rate reaches 5% OBS / M, a fire alarm signal is issued. The specific shading rate threshold can be selected from 5% OBS / M-15% OBS / M. The first smoke sensor 3, the temperature sensor 2 and the controller are used to effectively judge the occurrence of a fire, thereby improving the safety of the distribution box.

[0058] Furthermore, it also includes: an air extraction pipe 6, which is connected to the installation space; a compressor, one end of which is connected to the air extraction pipe 6; an air inlet, which is arranged at the lower end of the box body 1 and is connected to the installation space; and a filter 4, which is arranged at the air inlet. The compressor is electrically connected to the controller. When the temperature in the installation space is high but no fire alarm signal is generated, preferably, when the average temperature is greater than 60°C, the compressor is started by the controller to extract the air in the installation space to take away the heat in the installation space, and the outside air enters the filter 4 from the air inlet, and then enters the installation space, forming an air circulation, and continuously taking away the heat in the installation space. By installing the air inlet at the lower end of the box body 1, water can be prevented from entering while ventilation is performed.

[0059] Furthermore, it also includes: a detection tube 7; a front end cover 18, which is arranged on one side of the detection tube 7; a rear end cover 21, which is arranged on the other side of the detection tube 7, the detection tube 7, the front end cover 18 and the rear end cover 21 enclose a detection space, and the other end of the compressor is connected to the detection space; an exhaust port 8, which is arranged on the detection tube 7 and is connected to the detection space; a second smoke sensor is arranged in the detection space, and the second smoke sensor is electrically connected to the controller. At that time, although no fire alarm signal will be generated, it is also judged that there are certain hidden dangers. Since the gas in the installation space is generally not circulated, when the point where there is a safety hazard deviates from the first smoke alarm, the first smoke alarm is easy to fail to detect smoke. Therefore, at that time, the compressor is started to generate airflow in the installation space, which is convenient for the first smoke alarm to detect the smoke concentration, and the air drawn from the installation space enters the detection space of the detection tube 7, and is further detected by the second smoke alarm. When there is no smoke, the gas is discharged from the exhaust port 8.

[0060] Furthermore, it also includes: a high-pressure barrel 12, which is arranged in the detection space; an air outlet pipe 23, which is connected to the high-pressure barrel 12; a high-pressure stop valve 22, one end of which is connected to the air outlet pipe 23, and the other end of which is connected to the fire extinguishing pipe 10, and the fire extinguishing pipe 10 is connected to the installation space; a power source 249, which is connected to the high-pressure stop valve 22, and the power source 249 is electrically connected to the controller. Compressed carbon dioxide is stored in the high-pressure barrel 12. When the controller sends a fire alarm signal, the controller controls the power source 249 to start, open the high-pressure stop valve 22, and discharge the carbon dioxide into the installation space, so as to control the fire before the staff comes to deal with the fire, and the high-pressure barrel 12 will continue to release carbon dioxide, and the gas in the installation space will be pressed out from the air inlet, and the gas will flow, taking away the heat of the ignition point, and further controlling the fire. Since the high-pressure barrel 12 contains high-pressure carbon dioxide, when the electrical components in the box 1 work normally and produce a large temperature rise, such as when the average temperature in the installation space is greater than 60°C, the heat will also be transferred from the box 1 to the high-pressure barrel 12, causing the high-pressure barrel 12 to also produce a relatively large temperature rise. At this time, the airflow formed by the compressor will also take away the heat of the high-pressure barrel 12, thereby preventing the high-pressure barrel 12 from heating up and reducing its service life.

[0061] Further, the filter element 4 includes: a base 13, the base 13 is connected to the air inlet; a screw 14, the screw 14 is screwed to the base 13, and the screw 14 is screwed to the box body 1; a top cover 16, the top cover 16 is screwed to the screw 14; and a filter screen 17, the filter screen 17 is arranged between the base 13 and the top cover 16. The base 13 has a vertical extension portion, and the top cover 16 also has a vertical extension portion. The vertical extension portion of the base 13 faces the top cover 16, and the vertical extension portion of the top cover 16 faces the base 13. The filter screen 17 is fixed between the base 13 and the top cover 16 by bonding, tying, etc. The vertical extension portion of the base 13 and the vertical extension portion of the top cover 16 both have a limiting effect on the filter screen 17. The screw 14 is screwed to the box body 1, and the base 13 and the top cover 16 are both screwed to the screw 14, so that the main structure of the filter element 4 is fixed to the box body 1.

[0062] Furthermore, the filter element 4 further includes: a support member 15, the support member 15 is screwed to the screw rod 14 and abuts against the filter screen 17, and air leakage holes are arranged at intervals on the support member 15. The vertical extension portion limits the filter screen 17 in one direction, and the support member 15 limits the filter screen 17 in another direction to prevent the filter screen 17 from shifting during filtering or backwashing.

[0063] Furthermore, it also includes: a wire fixing member 11, which is installed on the box body 1, and a plurality of temperature sensors 2 are installed at intervals on the wire fixing member 11. The wire fixing member 11 is used for wiring, and preferably a plurality of holes are provided on the wire fixing member 11 for heat dissipation.

[0064] Furthermore, it also includes: a solenoid valve body, which is installed at the exhaust port 8 and is electrically connected to the controller. At that time, the exhaust port 8 is closed by the solenoid valve body, so that the gas remains in the detection space, which is beneficial to the detection of smoke.

[0065] Furthermore, it also includes: a first fastener 19, which is arranged between the front end cover 18 and the detection cylinder 7; and a second fastener 20, which is arranged between the rear end cover 21 and the detection cylinder 7. The first fastener 19 and the second fastener 20 are used to achieve a detachable connection, and the first fastener 19 and the second fastener 20 are preferably bolts.

[0066] Furthermore, it also includes: a sealing member, which is provided between the front cover 18 and the rear cover 21 and the detection tube 7. The sealing member is preferably a sealing ring to prevent foreign matter from entering the installation space through the detection tube 7.

[0067] The above-mentioned technical features can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
