[0020] Refer to the following Figures 1 to 10 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] A cable branch box with intelligent early warning, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9 As shown, it includes a branch box 1, a built-in cavity 2 is opened at the front end of the branch box 1, and the left and right ends of the branch box 1 are respectively rotatably connected with opening and closing doors, and the opening and closing doors are used to close and open the branch box 1 to protect the internal components. Exhaust boxes 3 are fixedly installed on the left and right outer ends of the branch box 1, and the exhaust boxes 3 are set to be through-through on the left and right. Fan racks are fixedly installed inside the two exhaust boxes 3, and fans 4 are installed on the fan racks. A trigger device is installed inside the built-in cavity 2, and a cooling box 5 located below the exhaust box 3 is fixedly installed on the left and right ends of the branch box 1. The inner end of the cooling box 5 is connected to the built-in cavity 2. The outer side of the two cooling boxes 5 is through-through, and the outer side is a closed end. A plurality of air outlet holes 6 are evenly arranged on the outer ends of the two cooling boxes 5. Under normal conditions, the air outlet holes 6 are used to discharge the air in the branch box 1 to realize the function of natural ventilation. A plurality of cable mounting seats 7 are evenly fixedly installed on the inner side of the branch box 1. Four cable mounting seats 7 are arranged here, and each of the cable mounting seats 7 is provided with four cable terminals 8. A protective box 50 is fixedly installed on the rear side wall of the built-in cavity 2. A plurality of cable mounting seats 7 are arranged in the protective box 50. The protective box 50 is provided with air holes to facilitate the heat dissipation of the cable and also protect the cable; When the temperature in the branch box 1 is high, the high temperature air is cooled through the air outlets 6 on both sides, thereby achieving the effect of cooling the branch box 1; When the temperature in the branch box 1 continues to rise, the high-temperature air will be detected by the trigger device, thereby starting the fan 4. The rapid rotation of the two fans 4 can quickly discharge the high-temperature air in the branch box 1 to the outside, thereby achieving a rapid cooling effect on the branch box 1. It can also effectively reduce the operating temperature of electrical components and avoid component failures caused by excessive temperature, thereby extending the service life of the components, ensuring the safe operation of the power grid, improving the utilization efficiency of electric energy, and reducing electric energy consumption.

[0022] like Figure 1 , Figure 3 As shown, the left and right outer ends of the branch box 1 are respectively fixedly mounted with side wall air outlet boxes 9, each side wall air outlet box 9 is arranged at the upper end of the exhaust box 3 on the same side, and the side wall air outlet boxes 9 are arranged through the left and right sides, and baffles 10 are respectively rotatably mounted on the outer ends of the two side wall air outlet boxes 9, and the upper ends of the baffles 10 are rotatably mounted on the corresponding side wall air outlet boxes 9. Under normal conditions, the baffles 10 are located in the corresponding side wall air outlet boxes 9, and the inner ends of the two baffles 10 are respectively provided with driving components; When the temperature in the branch box 1 rises, the lower end of the baffle 10 rotates outward, thereby opening the air outlet of the side wall air outlet box 9, and the high-temperature air is discharged outward through the side wall air outlet box 9, thereby accelerating the cooling speed of the branch box 1 and improving the cooling effect.

[0023] like Figure 4 As shown, the trigger device includes a trigger switch 11 and a sensor 12, and fixed blocks 13 are respectively fixedly installed on the left and right end walls of the built-in cavity 2, and the fixed block 13 is arranged on the rear side of the branch box 1. The trigger switches 11 are respectively fixedly installed on the bottom ends of the two fixed blocks 13, and the trigger switch 11 selects an existing suitable device, and the sensors 12 are respectively fixedly installed on the left and right end walls of the built-in cavity 2, and the sensor 12 is arranged on the front side of the branch box 1. The sensor 12 selects an existing temperature and humidity sensor, and a controller is fixedly installed on the branch box 1, and the trigger switch 11 and the sensor 12 are connected to the controller, and the controller is connected to an external power supply, and pads 14 are respectively fixedly installed on the left and right end walls of the built-in cavity 2, and the pads 14 are arranged correspondingly to the fixed blocks 13 on the same side, and telescopic rods 15 are respectively fixedly installed on the top ends of the two pads 14, and the telescopic rods 15 select existing suitable electric telescopic rods and are connected to the controller.

[0024] like Figure 4 , Figure 7As shown, the driving assembly includes a positioning shaft 18, and push blocks 17 are respectively fixedly installed on the inner ends of the two baffles 10, and a positioning shaft 18 is fixedly installed on each of the push blocks 17. A first connecting rod 19 is rotatably installed on both ends of each of the positioning shafts 18, and a connecting shaft 20 is rotatably installed between the lower ends of the two first connecting rods 19 located on the same side, and a second connecting rod 21 is rotatably installed on both ends of each of the connecting shafts 20, and a driving block 22 is rotatably installed on the lower ends of the two second connecting rods 21 located on the same side, and an extension plate 23 is fixedly installed on each of the driving blocks 22, and each extension plate 23 and each second connecting rod 21 are respectively connected to the inner wall of the branch box 1 in an up and down sliding manner, and the second connecting rod 21 and the extension plate 23 can only slide up and down along the branch box 1, and the rear end of the extension plate 23 extends to the top of the telescopic rod 15.

[0025] like Figure 4 , Figure 5 As shown, a first pulley 24 is installed on the inner end of each of the fans 4, and the first pulley 24 is coaxially fixedly connected to the rotating shaft of the fan 4. A second pulley 25 and a third pulley 26 are respectively installed on the left and right ends of each of the built-in chambers 2. The two second pulleys 25 are respectively rotatably connected to the rear inner wall of the branch box 1, and the two third pulleys 26 are respectively rotatably connected to the front inner wall of the branch box 1. The second pulley 25 and the third pulley 26 have the same specifications. The diameter of the first pulley 24 is twice that of the second pulley 25. A belt 27 is connected between the second pulley 25, the third pulley 26 and the first pulley 24 on the same side. Motors 28 are respectively installed on the left and right end walls of the built-in chamber 2, and the rotating shaft of the motor 28 is coaxially fixedly connected to the corresponding second pulley 25. Each motor 28 is fixedly connected to the branch box 1 through a connecting rod. The motor 28 is connected to the controller. A return spring is fixedly installed on the upper end of each extension plate 23, and the top end of the return spring is fixedly connected to the inner wall of the branch box 1. After the personnel have set the temperature and humidity values ​​detected by the sensor 12, when the temperature or humidity in the branch box 1 gradually increases, the air outlet 6 at this time is not enough to quickly cool down the branch box 1 and reduce the humidity. The sensor 12 detects a high temperature or humidity value and transmits a signal to the controller. The controller starts the telescopic rod 15 to extend upward, and the telescopic end of the telescopic rod 15 pushes the extension plate 23 to slide upward. The reset spring is compressed, and the second connecting rod 21 pushes the corresponding baffle 10 to rotate outward through the first connecting rod 19 to open the side wall air outlet box 9. At this time, the high-temperature gas or humid air can be emitted outward through the side wall air outlet box 9 and the air outlet 6, so as to quickly cool down or reduce the humidity of the air in the branch box 1, accelerate the air flow circulation inside the branch box 1, improve the air flow efficiency, and quickly reduce the temperature or humidity. When the side wall air outlet box 9 and the air outlet hole 6 are not sufficient to quickly cool down or dehumidify the temperature in the branch box 1 again, the sensor 12 at this time continues to control the telescopic rod 15 to push the extension plate 23 to extend upward, and the extension plate 23 at this time touches the trigger switch 11, and the trigger switch 11 starts the motor 28 to rotate, and the motor 28 drives the second pulley 25, the third pulley 26, the first pulley 24, and the fan 4 to rotate rapidly. The fan 4 can accelerate the gas flow in the branch box 1 during the rapid rotation process, and achieve the effect of rapid cooling or dehumidification of the branch box 1, and the branch box 1 can automatically adjust the cooling value or humidity value according to the change of the temperature value or the humidity value, which can reduce the damage of the electrical components in the branch box 1. Through two cooling or dehumidification, the device failure caused by high temperature or high humidity value can be effectively reduced, thereby extending the service life of the electrical components, and the heat dissipation conditions can also be improved, the power utilization efficiency can be improved, the energy consumption can be reduced, and the safety can be improved; When the sensor 12 detects that the temperature or humidity value is lower than the set value, the signal is transmitted to the controller, and the controller starts the telescopic rod 15 to retract and disengage from the contact with the trigger switch 11. Due to the rebound force of the reset spring, the baffle 10, the second connecting rod 21, and the first connecting rod 19 are reset, and the fan 4 stops rotating.

[0026] like Figure 4 , Figure 8 As shown, a dustproof mesh plate 29 is fixedly installed inside each of the cooling boxes 5, and the inner end surface of the dustproof mesh plate 29 is flush with the inner surface of the branch box 1. A slide groove 30 is respectively opened on the left and right inner ends of the branch box 1. The slide groove 30 is arranged on the front and rear sides of each dustproof mesh plate 29. A cleaning plate 31 is respectively installed between the two slide grooves 30 on the left and the two slide grooves 30 on the right to slide up and down. The cleaning plate 31 is evenly fixedly connected with bristles in contact with the dustproof mesh plate 29. Each of the cleaning plates 31 is fixedly installed with a convex Block 32, a tension spring 33 is fixedly installed at the lower end of each of the protrusions 32, a positioning block 34 is fixedly installed at the lower end of each of the tension springs 33, and the positioning block 34 is fixedly installed on the branch box 1. Under normal circumstances, due to the contraction force of the tension spring 33, the cleaning plate 31 is located below the dustproof screen plate 29, and a sector gear 35 is coaxially fixedly installed on each of the third pulleys 26. A vertical rack 36 is fixedly installed on the front end of each of the cleaning plates 31, and the vertical rack 36 is arranged close to the corresponding sector gear 35; The motor 28 drives the second pulley 25, the third pulley 26, the first pulley 24 and the fan 4 to rotate rapidly, the fan gear 35 engages with the vertical rack 36 and drives the corresponding cleaning plate 31 to move upward, and the tension spring 33 is in a stretched state. At this time, the cleaning plate 31 carries the bristles to clean the dust from the dustproof mesh plate 29. When the fan gear 35 disengages from the engagement of the vertical rack 36, due to the reset tension of the tension spring 33, the cleaning plate 31 at this time resets downward with the bristles to clean the dust from the dustproof mesh plate 29 again, which can prevent dust from clogging the dustproof mesh plate 29, thereby improving the rapid discharge of high-temperature air and improving the heat dissipation conditions.

[0027] like Figure 3 , Figure 5 , Figure 6 As shown, two plug blocks 37 are fixedly installed on the front end of each exhaust box 3, and a sliding hole is opened on the plug block 37. A plug rod 38 is slidably installed in the sliding hole of each plug block 37, and a tension spring is fixedly installed on each plug rod 38. The other end of the tension spring is fixedly installed on the plug block 37. A cover plate 39 is fixedly installed between the outer ends of the two plug rods 38 on the same side. Under normal circumstances, the cover plate 39 covers the corresponding exhaust box 3, and a plurality of semicircular blocks 40 are evenly fixedly installed on the inner end of each cover plate 39. A gap is provided between every two semicircular blocks 40. The plurality of semicircular blocks 40 on the same side form a circular structure, and the other end of each semicircular block 40 is a semicircular structure. An extrusion rod 41 is fixedly installed on the outer end of the rotating shaft of each fan 4. The extrusion rod 41 is arranged on the eccentric side of the rotating shaft of the fan 4, and the other end of the extrusion rod 41 is a circular surface structure. The fan 4 rotates with the extrusion rod 41, and the extrusion rod 41 slides from the gap between the two semicircular blocks 40 to the corresponding semicircular block 40. At this time, the round surface of the extrusion rod 41 slides against the outside of the semicircular block 40, and pushes the semicircular block 40, the cover plate 39 and the insertion rod 38 to slide outward. The tension spring is in a stretched state, so that the cover plate 39 is disengaged from the outer port of the exhaust box 3, and the outer end surface of the exhaust box 3 is opened, and the high-temperature air in the branch box 1 is quickly discharged to the outside through the exhaust box 3; When the extrusion rod 41 slides to the highest point of the semicircular block 40, the exhaust box 3 is opened to the maximum and the cooling effect is the best. Then the extrusion rod 41 slides into the gap between the two semicircular blocks 40 again, and the tension spring brings the insertion rod 38, the semicircular block 40, and the cover plate 39 to reset. Then the above steps are repeated to achieve cooling or dehumidification in the branch box 1. When the branch box 1 is at room temperature, the cover plate 39 covers the exhaust box 3, which to a certain extent also plays a protective role for the fan 4. Since the fan 4 rotates at a fast speed, the high-temperature air can be discharged quickly, thereby improving the cooling effect.

[0028] like Figure 2 , Fig. 9As shown, a mounting cavity 42 is provided at the front end of each of the cable mounting seats 7, and a limiting frame 43 is respectively installed at the left and right ends of each of the mounting cavity 42, and the limiting frame 43 is fixedly connected to the cable mounting seat 7, and a clamping plate 44 is installed between the corresponding two limiting frames 43 so as to slide up and down, and a plurality of extrusion springs 45 are evenly and fixedly installed on each of the clamping plates 44, and the other end of each extrusion spring 45 is fixedly connected to the outer end of the cable mounting seat 7, and a clamping block 46 is provided between the corresponding two clamping plates 44, and the cable terminal 8 is fixedly installed on the clamping block 46. Under normal circumstances, due to the rebound force of the extrusion spring 45, the two clamping plates 44 can clamp the clamping block 46.

[0029] like Fig. 9 , Fig.10 As shown, a connecting block 47 is fixedly installed between each of the limiting frames 43 and the outer end of the cable mounting seat 7, and a round hole is opened on the connecting block 47. A pressing rod 48 is slidably installed in the round hole. A pushing block is fixedly installed on the inner end of each pressing rod 48. Two pushing rods 49 are rotatably installed on both ends of each pushing block, and the other end of each pushing rod 49 is rotatably installed on the corresponding clamping plate 44. When installing the clamping block 46, the personnel drives the pressing rod 48 to move toward the rear end of the cable mounting seat 7, and the two pushing rods 49 drive the corresponding two clamping plates 44 to move away from each other. The extrusion spring 45 is compressed, and the personnel holds the clamping block 46 and places it between the two clamping plates 44, and releases the pressing rod 48. Due to the rebound force of the extrusion spring 45, the clamping plate 44 can clamp the clamping block 46 at this time. Compared with the existing bolt installation of the cable terminal 8, this installation method is more convenient, and the cable terminal 8 can also be quickly replaced and repaired, which improves the replacement efficiency and is more convenient to operate.

[0030] Working principle of the present invention: Under normal conditions, the air in the branch box 1 is cooled through the air outlets 6 on both sides, thereby achieving the effect of cooling or dehumidifying the branch box 1; When the temperature or humidity value in the branch box 1 gradually increases, the air outlet 6 at this time is not enough to quickly cool down or dehumidify the branch box 1. The sensor 12 detects the value and transmits the signal to the controller. The controller starts the telescopic rod 15 to extend upward. The telescopic end of the telescopic rod 15 pushes the extension plate 23 to slide upward. The reset spring is compressed, and the second connecting rod 21 pushes the corresponding baffle 10 to rotate outward through the first connecting rod 19 to open the side wall air outlet box 9. At this time, the high-temperature gas or high-humidity air can be emitted outward through the side wall air outlet box 9 and the air outlet 6, so as to quickly cool down or dehumidify the air in the branch box 1. When the side wall air outlet box 9 and the air outlet hole 6 are not sufficient to quickly cool down or dehumidify the temperature in the branch box 1 again, the sensor 12 at this time continues to control the telescopic rod 15 to push the extension plate 23 to extend upward, and the extension plate 23 at this time touches the trigger switch 11, and the trigger switch 11 starts the motor 28 to rotate, and the motor 28 drives the second pulley 25, the third pulley 26, the first pulley 24, and the fan 4 to rotate rapidly. The fan 4 can accelerate the gas flow in the branch box 1 during the rapid rotation process, and achieve the effect of rapid cooling or dehumidification of the branch box 1, and the branch box 1 can automatically adjust the cooling or humidity frequency according to the changes in the temperature value or the humidity value, so as to reduce the damage of the electrical components in the branch box 1, effectively reduce the failure of the device, thereby prolonging the service life of the electrical components, and can also improve the heat dissipation conditions, improve the efficiency of electric energy utilization, reduce energy consumption, and improve safety; When the sensor 12 detects that the temperature or humidity value is lower than the set value, the signal is transmitted to the controller, and the controller starts the telescopic rod 15 to retract and disengage from the contact with the trigger switch 11. Due to the rebound force of the reset spring, the baffle 10, the second connecting rod 21, and the first connecting rod 19 are reset, and the fan 4 stops rotating.
