[0023] (3) Beneficial effects

[0024] Compared with the existing technology, the present invention provides an intelligent primary and secondary fusion ring network box with the following beneficial effects:

[0025] 1. This intelligent primary and secondary fusion ring network box has a double-layer hollow structure by setting the box top cover and the box back wall. The ventilation system takes in air from the bottom tray of the box upwards, passes through the outer box and reaches the exhaust fan on the top. The exhaust fan introduces the gas exhausted from different outer boxes into different ventilation cavities, and uses each gas detection device to detect the gas components in the corresponding cavity, so as to accurately determine the burnt location in the event of a fire. In addition, different exhaust fans can be controlled by the values ​​of the temperature sensors in each inner box, so as to control the heat dissipation power in a block-like manner according to the heat generation, thereby improving the heat dissipation effect.

[0026] 2. This intelligent primary and secondary fusion ring network box sets up a ventilation system from bottom to top and then downward, so that the air inlet is located on both sides of the bottom and the air outlet is located on the rear side of the bottom, avoiding rainwater infiltration when it is set at the top, and expanding the circulation range of the ventilation system, thereby improving heat dissipation efficiency.

[0027] 3. The intelligent primary and secondary integrated ring network box, by setting up the ventilation system, sets the box top cover, front door, box side wall, box bottom tray, and box back wall to a double-layer hollow structure. On the one hand, it improves the anti-collision ability when subjected to external impact, and avoids direct damage to the inner box when it is concave inward. On the other hand, the double-layer structure improves the moisture-proof effect, so that the inner wall is not directly in contact with the outside world, avoiding water vapor condensation and causing moisture on the inner wall, and also improves the insulation effect. The double-layer structure can use low-strength insulation materials for the inner layer and metal materials with strong anti-corrosion effects for the outer layer. At the same time, the hollow structure can facilitate the routing of wires in the cavity.

[0028] 4. This intelligent primary and secondary integrated ring network box is equipped with a wire arrangement dust prevention device and a flow rate adjustment device on both sides of the inner layer of the back wall of the box. The baffle is used to adjust the flow rate of the middle circulation area during the lifting process. When the number of wires increases, the flow rate of the middle circulation area is controlled to increase. A large number of wires means a large gap between the wires, and dust is more likely to enter. When the flow rate increases, the dust will be driven and discharged by the airflow, and the dust cannot enter the rear wire arrangement hole against the airflow. The wire arrangement port and the air outlet are combined to improve the dust prevention effect.

[0029] 5. This intelligent primary and secondary fusion ring network box is equipped with a cylinder on the wiring dust prevention device and a comb-shaped card and a comb-shaped card slot on the flow rate adjustment device. When the gas detection device detects abnormal gas components in the air, the control cylinder pushes the adjustment block to move upward, thereby driving the baffle to rise. The rising baffle drives the direct slider to rise, and the rising direct slider pushes the top rod to rise. The comb-shaped card is lifted into the comb-shaped card slot to block the three circulation areas, and the air inlet in the bottom tray of the control box is blocked to prevent the gas circulation from bringing in oxygen to support combustion after a fire, providing time for maintenance workers and firefighters to arrive.

[0049] Example 1:

[0050] This embodiment provides an intelligent primary-secondary fusion ring network box with the following technical features.

[0051] See also Figures 1-14 , an intelligent primary and secondary fusion ring network box, including an outer box 2 and multiple inner boxes 1 arranged in the outer box 2, the outer box 2 is composed of a box top cover 21, a front door 22, a box side wall 23, a box bottom tray 24 and a box back wall 25, the box top cover 21, the box side wall 23, the box bottom tray 24 and the box back wall 25 are all hollow structures, a plurality of exhaust fans 211 are arranged on the inner plate of the box top cover 21, each exhaust fan 211 is located above the top air outlet of the corresponding inner box 1, and the air inside the box top cover 21 is The cavity is divided into multiple separate upper ventilation cavities by setting multiple upper partition plates 212. Each exhaust fan 211 is connected upward to a different ventilation cavity. The cavity of the box back wall 25 is divided into multiple separate rear ventilation cavities by a vertical rear partition plate 253. The rear ventilation cavity in each box back wall 25 is connected to the corresponding upper ventilation cavity in the box top cover 21 to form a separate ventilation cavity. A back wall air outlet 256 is set at the bottom of the outer plate of the box back wall 25, and a gas detection device is set in each ventilation cavity.

[0052] The line inlet and air inlet positions of the ring network box are both arranged in the bottom tray 24 of the box. A rear wiring hole 251 is arranged on the inner plate of the back wall 25 of the box. The line passes through the bottom tray 24 upward through the rear ventilation cavity and then connects to the inner box 1 from the rear wiring hole 251. The bottom tray 24 is provided with bottom wall air inlets 241 on both sides and a bottom wall air outlet 242 on the upper surface. The bottom wall air outlet 242 is located below the bottom air inlet of the inner box 1.

[0053] It should be noted that the outer box 2 is set above the base 3, the base 3 is higher than the ground, and the edge of the base 3 is slightly larger than the edge of the bottom tray 24.

[0054] Furthermore, a cable dust prevention device 252 is provided on the inner side of the rear cable hole 251 on the back wall 25 of the box. The cable dust prevention device 252 includes a baffle 2521 that is raised and lowered on the rear cable hole 251. The baffle 2521 slides in the slide seats 2522 on both sides. A connecting plate 2523 is fixedly connected to the baffle 2521. A vertical guide column 2524 is fixed on the connecting plate 2523. The other end of the guide column 2524 passes through the adjusting block 2525. A spring is provided between the adjusting block 2525 and the connecting plate 2523.

[0055] Furthermore, a flow rate regulating device 255 is provided on the outer side of the rear cable hole 251 on the back wall 25 of the box. Two vertical partition plates 254 are provided in each rear ventilation cavity in the back wall 25 of the box. Each partition plate 254 divides a rear ventilation cavity into three separate flow areas. The rear cable hole 251 is connected to the flow area in the middle position. The flow rate regulating device 255 includes:

[0056] A direct slider 2553 is connected to the baffle 2521 and is rotatably connected to two symmetrical side push rods 2554;

[0057] The side push rod 2554 has one end rotatably connected to the liftable direct slider 2553 and the other end rotatably connected to the drainage baffle 2555;

[0058] Drainage baffle 2555, each partition plate 254 is provided with an opening slot 2541, and the position of the opening slot 2541 is provided with a drainage baffle 2555 whose bottom is rotatably connected to the partition plate 254;

[0059] When the baffle 2521 rises, it drives the direct slider 2553 to rise, thereby using the side push rod 2554 to drive the drainage baffle 2555 to rotate and open to both sides. Since the height of the baffle 2521 is determined by the number of wires, the air flow speed in the middle circulation area can be controlled according to the number of wires.

[0060] It is further provided that the gas detection device is at least one of an electrochemical gas sensor, a semiconductor gas sensor, an infrared absorption gas analyzer and a photoionization gas sensor. The electrochemical gas sensor works based on the principle of chemical reaction and has significant advantages in detecting acidic gases such as sulfur dioxide and nitrogen dioxide produced by short-circuit combustion in the ring network cabinet. These gases react chemically with the electrolyte inside the sensor to produce a current signal proportional to the gas concentration. The gas concentration can be accurately determined by detecting the current. The sensor has high precision and good selectivity, can effectively avoid interference from other gases, accurately detect the target gas, and provide a reliable basis for ring network cabinet fault judgment; the semiconductor gas sensor uses the characteristic of the change in resistance value after the semiconductor contacts the gas to detect gases such as carbon monoxide produced by short-circuit combustion in the ring network cabinet, which will cause the semiconductor surface to adsorb gas molecules, thereby causing the resistance value to change. By measuring the resistance change, the Carbon monoxide concentration, it is low cost and fast response, can react to changes in gas concentration in the ring network cabinet in a short time and issue early warning signals in time, but the disadvantage is poor selectivity and susceptibility to other gases; infrared absorption gas analyzer, each gas has a unique infrared absorption spectrum. When infrared light passes through the environment containing short-circuit combustion-produced gases such as carbon dioxide in the ring network cabinet, infrared light of a specific wavelength will be absorbed by carbon dioxide. By detecting the change in infrared light intensity before and after absorption, the concentration of carbon dioxide can be accurately analyzed. It can also be used to detect other characteristic gases. The analyzer has good stability and high precision, can operate stably for a long time, and provides accurate data for ring network cabinet gas detection, but the price is relatively high; photoionization gas sensor, which can detect volatile organic compounds (VOCs) produced by short-circuit combustion in the ring network cabinet, uses ultraviolet light to irradiate the gas to ionize the gas molecules. The generated ion current is related to the gas concentration, and the VOCs concentration is determined by detecting the ion current. This sensor has high sensitivity and can detect extremely low concentrations of volatile organic compounds, which can quickly discover early fault hazards in the ring network cabinet.

[0061] Furthermore, a cylinder 2526 is provided in the wiring dust prevention device 252, and the cylinder 2526 is fixed on the back wall 25 of the box. The end of the push-pull rod of the cylinder 2526 is connected to the adjustment block 2525. The flow rate adjustment device 255 also includes a comb-shaped card 2556, which is located in the rear ventilation cavity and slides up and down. A push rod 2557 is provided below the comb-shaped card 2556, and a comb-shaped card slot 2558 corresponding to the push rod 2557 is provided at the same horizontal position in the three circulation areas of a rear ventilation cavity. When the gas detection device detects that the gas composition in the air is abnormal, the control cylinder 2526 pushes the adjustment block 2525 to move upward, thereby driving the baffle 2521 to rise. The rise of the baffle 2521 drives the direct slider 2553 to rise. The rise of the direct slider 2553 pushes the push rod 2557 to lift. The comb-shaped card 2556 is lifted into the comb-shaped card slot 2558 and then blocks the three circulation areas.

[0062] Furthermore, side baffles 2511 are slidably connected on both sides of the rear cable hole 251, and limit blocks 2512 are set on the side baffles 2511. Under normal circumstances, the limit blocks 2512 are blocked by the sides of the baffles 2521 and hidden in the slide 2522. When the baffles 2521 rise to a position that is free from the limit blocks 2512, the side baffles 2511 pop out from both sides under the action of the spring to block the rear cable hole 251.

[0063] It should be noted that the side baffle 2511 is a soft elastic pad, which can fit on the line when the rear cable hole 251 is blocked, or the side baffle 2511 is composed of multiple freely sliding sliding blocks, which can change the edge shape of the side baffle 2511 according to the shape of the line when the rear cable hole 251 is blocked, so as to fit better.

[0064] It is further provided that the direct slider 2553 is connected to the baffle 2521 through the vertical push rod 2552 and the indirect slider 2551, the baffle 2521 is fixedly connected to the back of the baffle 2521, and the two ends of the vertical push rod 2552 are rotatably connected to the indirect slider 2551 and the direct slider 2553 respectively, and the indirect slider 2551 and the direct slider 2553 are both located on the inner plate of the back wall 25 of the box and slide vertically.

[0065] It should be noted that the direct slider 2553, the vertical push rod 2552 and the indirect slider 2551 are located in the middle circulation area of ​​the three circulation areas. The rotation of the diversion baffle 2555 to both sides refers to the rotation to the two circulation areas on both sides, thereby intercepting the airflow in the circulation areas on both sides to the middle circulation area, thereby increasing the flow rate in the middle circulation area when the number of lines in the rear wiring hole 251 increases, thereby achieving a dust prevention effect.

[0066] It should also be noted that the vertical push rod 2552 and the side push rod 2554 are elastic connecting rods, which are composed of two sleeve rods that are connected to each other and slide relative to each other. Springs are also provided on the outside of the two relatively sliding sleeve rods, so that the elastic connecting rod has a telescopic function and elastic effect while ensuring verticality.

[0067] Furthermore, an elastic pad is provided at the bottom of the baffle 2521, and the bottom edge of the elastic pad is wavy.

[0068] Furthermore, a temperature sensor is provided in each inner box 1 , and the power of the corresponding exhaust fan 211 is controlled by the temperature sensor, thereby controlling the wind speed of the exhaust fan 211 .

[0069] Furthermore, the box top cover 21, the front door 22, the box side walls 23, the box bottom tray 24 and the box back wall 25 are all double-layer hollow structures, wherein the inner layer is an insulating plastic plate and the outer layer is a metal plate coated with an insulating layer.

[0070] It is further provided that the top of the box top cover 21 is a triangular sloping top.

[0071] It is further provided that the cavity of the bottom tray 24 of the box is divided into a plurality of separate lower ventilation cavities by a lower partition plate 243, and each lower ventilation cavity is provided with a waterproof slope 244 at the position of the bottom wall air inlet 241, and an electronic switch device is provided at the bottom wall air inlet 241. When the gas detection device detects that the gas components in the air are abnormal, the electronic switch device is controlled to block the bottom wall air inlet 241.

[0072] It should be noted that the bottom tray 24 is provided with wire inlet and outlet holes, and the bottom wall air outlet 242 is provided with a wire arrangement hole at a position corresponding to the cavity in the back wall 25 of the box.

[0073] It should be noted that the electronic switch device includes a comb-toothed card and a comb-toothed card slot, wherein the comb-toothed card is connected to the push rod of the cylinder. When the gas detection device detects abnormal gas components in the air, the cylinder pushes the comb-toothed card so that it is stuck in the comb-toothed card slot, thereby blocking the bottom wall air inlet 241.

[0074] It is further provided that the inner plate of the box back wall 25 is composed of a plurality of separate plates, each of which can be detachably mounted on the rear interlayer plate 253, thereby facilitating the installation of circuits.

[0075] To sum up, the intelligent primary and secondary fusion ring network box, by setting the box top cover 21 and the box back wall 25 as a double-layer hollow structure, allows the ventilation system to take in air upward from the box bottom tray 24, and after passing through the outer box 2, it reaches the exhaust fan 211 at the top. The exhaust fan 211 introduces the gas exhausted from different outer boxes 2 into different ventilation cavities, and uses each gas detection device to detect the gas components in the corresponding cavity, so as to accurately determine the burnt position in the event of a fire, and different exhaust fans 211 can be controlled by the value of the temperature sensor in each inner box 1, so as to control the heat dissipation power in a block manner according to the heat generation, thereby improving the heat dissipation effect.

[0076] This intelligent primary and secondary fusion ring network box sets up a ventilation system from bottom to top and then downward, so that the air inlet is located on both sides of the bottom and the air outlet is located on the rear side of the bottom, avoiding rainwater infiltration when set at the top, and expanding the circulation range of the ventilation system, thereby improving heat dissipation efficiency.

[0077] The intelligent primary and secondary integrated ring network box is provided with the ventilation system, and the box top cover 21, front door 22, box side wall 23, box bottom tray 24, and box back wall 25 are all set to a double-layer hollow structure. On the one hand, the anti-collision ability when subjected to external impact is improved, and direct damage to the inner box 1 when it is concave inward is avoided. On the other hand, the double-layer structure improves the moisture-proof effect, so that the inner wall is not directly in contact with the outside world, avoiding condensation of water vapor and causing moisture on the inner wall, and also improves the insulation effect. The double-layer structure can use low-strength insulating materials in the inner layer and metal materials with strong anti-corrosion effects in the outer layer. At the same time, the hollow structure can facilitate the routing of wires in the cavity.

[0078] This intelligent primary and secondary integrated ring network box is equipped with a wire arrangement and dust prevention device 252 and a flow rate adjustment device 255 on both sides of the inner layer of the box back wall 25, and uses a baffle 2521 to adjust the flow rate of the middle circulation area during the lifting process. When the number of wires increases, the flow rate of the middle circulation area is controlled to increase. A large number of wires means a large gap between the wires, and dust is more likely to enter. When the flow rate increases, the dust will be driven and discharged by the airflow, and the dust cannot enter the rear wire arrangement hole 251 against the airflow. The wire arrangement port and the air outlet are combined to improve the dust prevention effect.

[0079] The intelligent primary and secondary fusion ring network box is provided with a cylinder 2526 on the wiring dust prevention device 252, and a comb-shaped card 2556 and a comb-shaped card slot 2558 on the flow rate adjustment device 255. When the gas detection device detects that the gas composition in the air is abnormal, the control cylinder 2526 pushes the adjustment block 2525 to move upward, thereby driving the baffle 2521 to rise. The rising of the baffle 2521 drives the direct slider 2553 to rise. The rising of the direct slider 2553 pushes the top rod 2557 to rise. The comb-shaped card 2556 is lifted into the comb-shaped card slot 2558 to block the three circulation areas, and the air inlet in the bottom tray 24 of the control box is blocked to prevent the gas circulation from bringing in oxygen to support combustion after a fire, thereby providing time for maintenance workers and firefighters to arrive.
