Description
Technical Field
[0001] The invention relates to the technical field of explosion-proof street lamps, in particular to an explosion-proof solar street lamp with an automatic detection function. Background Art
[0002] Solar street lights mainly convert solar energy into electrical energy through photovoltaic panels, store the electrical energy in electrical boxes, and power light-emitting devices such as LED lamps. Because solar energy is a clean new energy source and is green and environmentally friendly, solar street lights are widely used in various workplaces, including densely populated squares, factory warehouses, and hazardous goods storage areas. In these scenarios, street lights need to improve their safety levels to ensure that the batteries of the street lights do not explode and cause casualties and property losses.
[0003] Due to the widespread application of solar street lights, some are used in factories or densely populated areas. Since solar street lights need to use photovoltaic panels to convert solar energy, the battery pack needs to be frequently inspected and maintained, so the battery pack cannot be buried underground. In the process of long-term sunlight exposure and long-term use, the battery pack will heat up. Once the battery pack explodes, it will cause serious losses to factories or densely populated areas, and the battery pack needs to be explosion-proof. Summary of the invention
[0004] The object of the present invention is to provide an explosion-proof solar street light with an automatic detection function to solve the problems in the prior art.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an explosion-proof solar street light with automatic detection function comprises a lamp holder, a lamp pole, a rotating frame, a photovoltaic panel, a lamp group, a mounting frame and an explosion-proof electric box, the lamp pole and the lamp holder, the rotating frame, the lamp group and the mounting frame are all fixedly connected, the photovoltaic panel and the rotating frame are hinged, the explosion-proof electric box and the mounting frame are fixedly connected, the explosion-proof electric box and the photovoltaic panel are connected by electric wires, and the explosion-proof electric box and the lamp group are connected by electric wires.
[0006] The present invention is a method of utilizing photovoltaic panels to convert solar energy into electrical energy, and storing the electrical energy in an explosion-proof electrical box. The explosion-proof electrical box supplies power to a lamp assembly. When the explosion-proof electrical box transmits electrical energy, internal batteries will generate heat energy. The heat energy accumulated in the explosion-proof electrical box will cause the batteries to explode and spontaneously combust, causing danger. When storing and releasing electrical energy, the explosion-proof electrical box automatically detects the temperature rise of different internal areas, exhausts and dissipates heat in the temperature rise areas, and releases pressure to avoid explosions. When the weather is cold and the temperature is low, the efficiency of the battery in converting electrical energy decreases. The internal area below the optimal discharge temperature is detected, and local temperature compensation is performed to keep the battery at a temperature with optimal electrical energy conversion efficiency.
[0007] Furthermore, the explosion-proof electrical box includes a box body, a battery pack, a detection mechanism and a pressure relief mechanism. The box body is fixedly connected to the mounting frame. Two groups of first through holes are provided on the box body. One group of first through holes is connected to the photovoltaic panel through wires, and the other group of first through holes is connected to the lamp group through wires. The battery pack is connected to the photovoltaic panel and the lamp group through wires. The battery pack and the pressure relief mechanism are fixedly connected to the box body. Several groups of thermal conductive copper plates are provided on the battery pack. The several groups of thermal conductive copper plates are linearly evenly distributed on the side walls of the battery pack in the vertical direction. The detection mechanism is in contact with the thermal conductive copper plates. Two groups of pressure relief mechanisms are provided. The two groups of pressure relief mechanisms are located on both sides of the battery pack. The detection mechanism is connected to the pressure relief mechanism through electrical signals.
[0008] The battery pack is divided into several heat dissipation zones arranged equally by linearly distributing several groups of thermal conductive copper plates on the side walls of the battery pack. The temperature of the battery pack is transmitted to the detection mechanism by the thermal conductive copper plates. The detection mechanism detects the temperature rise of the battery pack in the corresponding temperature rise area of the thermal conductive copper plates and transmits an electrical signal to the pressure relief mechanisms on both sides. The pressure relief mechanisms open the vents at the corresponding positions to discharge the internal heated gas to the outside of the box while releasing the pressure. When the detection mechanism detects that the battery pack is lower than the optimal discharge temperature, local temperature compensation is performed to bring the battery to a temperature with optimal electrical energy conversion efficiency.
[0009] Furthermore, the detection mechanism includes a first base frame, a first motor, a first worm, a worm seat, a slide, a thermal resistance mechanism and a compensation mechanism. The first base frame is fixedly connected to the housing and the first motor. The output end of the first motor is fixedly connected to the first worm. The worm seat is provided with a threaded hole and a second through hole. The first worm is connected to the threaded hole by a thread. The slide is fixedly connected to the battery pack. The worm seat is slidably connected to the slide. The second through hole is fixedly connected to the thermal resistance mechanism. The thermal resistance mechanism is in contact with the temperature-conducting copper plate. The thermal resistance mechanism is fixedly connected to the compensation mechanism. The thermal resistance mechanism is connected to the compensation mechanism and the pressure relief mechanism through electrical signals.
[0010] The temperature of the battery pack is transmitted to the thermal resistance mechanism through the thermal conductive copper plate, and the first motor outputs torque to the first worm. Through the threaded connection between the first worm and the threaded hole on the worm seat, the rotation of the first worm is converted into reciprocating sliding of the worm seat along the slide. The worm seat drives the thermal resistance mechanism to slide along the thermal conductive copper plate. The heating conditions of different areas on the thermal conductive copper plate are detected by sliding of the thermal resistance mechanism. The thermal resistance mechanism transmits electrical signals to the pressure relief mechanisms on both sides. When the weather is cold and the temperature is low, the compensation mechanism actively generates heat to the thermal resistance mechanism to raise the thermal resistance mechanism to the optimal discharge temperature. The thermal resistance mechanism detects the area where the temperature of the thermal conductive copper plate is lower than the optimal discharge temperature, and the compensation mechanism adjusts the heating position to perform precise temperature rise thermal compensation on the back of the battery pack.
[0011] Furthermore, the thermal resistance mechanism includes a loop pipe, an electrode clamp, an ammeter and a mounting plate. The loop pipe is fixedly connected to the second through hole and the compensation mechanism. The electrode clamps and the ammeter are provided in several groups. Several groups of electrode clamps are in contact with the temperature conductive copper plates. The mounting plate is fixedly connected to the electrode clamps and the ammeter. The ammeter is connected to the compensation mechanism and the pressure relief mechanism through electrical signals.
[0012] When the temperature of the thermal conductive copper plate rises due to the battery pack, there is a temperature difference between the electrode clamp and the thermal conductive copper plate. The temperature difference between the two different conductors generates current. Several groups of vertically arranged ammeters slide horizontally along the thermal conductive copper plate to various areas, and the heating area of the battery pack is obtained by superimposing the two-axis coordinates. When the compensation mechanism actively generates heat, the heat is transferred to the electrode clamp through the loop pipe, causing a temperature difference between the electrode clamp and the thermal conductive copper plate.
[0013] Furthermore, the compensation mechanism includes a base plate, a second motor, a bevel gear set, a second worm and a thermal resistor ring. The base plate is fixedly connected to the loop pipe and the second motor. The loop pipe is provided with a third through hole and a slide rail. The output end of the second motor is rotationally connected to the third through hole. The bevel gear set is transmission-connected to the output end of the second motor and the second worm. The thermal resistor ring is provided with an inner wall thread. The second worm is threadedly connected to the inner wall thread. The thermal resistor ring is slidably connected to the slide rail. The second motor and the thermal resistor ring are connected to the ammeter through electrical signals.
[0014] When the weather is cold and the temperature is low, the gas in the thermal resistor coil heating loop pipe provides heat for the electrode clamp. When the ammeter obtains the coordinates of the area where the battery pack heats up slowly, it sends an electrical signal to the second motor. The second motor outputs torque to the bevel gear set. The second worm is rotated around its axis through the changing torque of the bevel gear set. The threaded connection between the second worm and the inner wall thread on the thermal resistor coil converts the rotation of the second worm into the upward and downward movement of the thermal resistor coil along the slide rail, and the thermal resistor coil is moved to the area where the battery pack heats up slowly. The heat of the thermal resistor coil itself is transferred through the loop pipe to perform temperature compensation on the area.
[0015] Furthermore, the pressure relief mechanism includes an outer shell, a cylinder, an articulated connecting rod, a top plate, a baffle, a grille, a switch mechanism and an exhaust mechanism. The outer shell is fixedly connected to the box body, the cylinder, the grille and the switch mechanism. The output end of the cylinder is hinged to the articulated connecting rod. A convex column is provided on the top plate. The end of the articulated connecting rod away from the cylinder is rotatably connected to the convex column. The baffle is fixedly connected to the top plate. The baffle is rotatably connected to the outer shell. A plurality of groups of ventilation ducts are provided on the outer shell. The plurality of groups of ventilation ducts are linearly evenly distributed along the side wall of the outer shell. The ventilation ducts are fixedly connected to the exhaust mechanism. The switch mechanism is in contact with the exhaust mechanism. The switch mechanism is connected to the ammeter through electrical signals.
[0016] The cylinder pushes the hinged connecting rod reciprocatingly, and through the rotational connection between the hinged connecting rod and the convex column on the top plate, the baffle is driven to rotate around its central axis. The reciprocating rotation of the baffle makes the spaces on both sides reciprocally connected. When the ammeter obtains the coordinates of the abnormally heated area of the battery pack, an electrical signal is generated to the switch mechanism, and the switch mechanism opens the exhaust mechanism at the corresponding position. When the exhaust mechanism at the corresponding position is connected to both sides when the baffle rotates, the overheated air at the corresponding position in the box is discharged and the pressure is relieved, and normal temperature gas is added to the inside of the box through the exhaust mechanisms at other positions to cool the battery pack.
[0017] Furthermore, the switch mechanism includes a second base frame, a third motor and a control column. The second base frame is fixedly connected to the third motor and the outer shell. The third motor is connected to the ammeter through an electrical signal. The output end of the third motor is fixedly connected to the control column. The control column is in contact with the exhaust mechanism. A plurality of groups of grooves are provided on the control column. The plurality of groups of grooves are arranged on the side wall of the control column and are evenly distributed along the axis in a spiral.
[0018] The third motor outputs torque to the control column according to the electrical signal sent by the ammeter, driving the control column to rotate. When the edge of the side wall of the control column contacts the exhaust mechanism, the exhaust mechanism is sealed and does not transmit overheated air. When the groove on the control column contacts the exhaust mechanism, the exhaust mechanism at the corresponding position opens. The pressure of the gas inside the box increases due to the expansion of the battery pack, and is discharged to the outside through the opened exhaust mechanism. At the same time, the control column continues to rotate, so that the adjacent grooves evenly distributed in the spiral contact the adjacent exhaust mechanism, and the adjacent exhaust mechanism opens. At this time, the box is in a negative pressure state because a large amount of exhaust has just been discharged, and the external normal temperature air is replenished into the inside of the box along the adjacent exhaust mechanism.
[0019] Furthermore, the exhaust mechanism includes a hole frame, a connecting column, a sealing bead, a limit plate, a limit spring, a compression spring, a cross frame and a hole plate. The hole frame, the limit spring, the cross frame and the hole plate are all fixedly connected to the ventilation duct, the connecting column is slidably connected to the hole frame, the sealing bead, the limit plate and the compression spring are all fixedly connected to the connecting column, and the compression spring is fixedly connected to the cross frame.
[0020] When the edge of the side wall of the control column contacts the sealing bead, the connecting column is pushed to slide along the hole frame toward the direction close to the horizontal frame, the limit plate on the connecting column breaks through the limit spring piece, and the sealing bead contacts the hole plate to achieve a sealing effect; when the groove on the control column rotates to the corresponding position, the sealing bead no longer contacts the edge of the side wall of the control column; under the action of the compression spring restoring the deformation, the limit plate breaks through the limit spring piece in the direction away from the horizontal frame, the sealing bead contacts the groove on the control column, and the superheated air enters the ventilation duct through the hole plate.
[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a detection mechanism, the first motor outputs a torque to, and through the threaded connection with the threaded hole, the rotation of the first worm is converted into the reciprocating sliding of the worm seat along the slide, driving the electrode clamp to slide along the thermal conductive copper plate, and the temperature of the battery pack is transferred from the thermal conductive copper plate to the electrode clamp. There is a temperature difference between the electrode clamp and the thermal conductive copper plate to generate current, and the superposition of the two-axis coordinates obtains the heating area of the battery pack; the present invention designs a compensation mechanism, when the weather is cold and the temperature is low, the efficiency of battery conversion of electrical energy decreases, the gas in the thermal resistor coil heating loop pipe provides heat for the electrode clamp, and the ammeter sends an electrical signal to the second motor of the coordinates of the slow heating area of the battery pack to the second motor, and the second motor outputs a torque to the bevel gear set, converting the rotation of the second worm into the displacement of the thermal resistor coil along the slide rail, moving the thermal resistor coil to the slow heating area of the battery pack, and transferring heat through the loop pipe through the heat of the thermal resistor coil itself to compensate for the temperature of the area; the present invention designs an exhaust mechanism, the third The motor outputs torque according to the electrical signal sent by the ammeter to drive the control column to rotate. When the edge of the side wall of the control column contacts the sealing bead, the sealing bead contacts the orifice plate to achieve a sealing effect. When the groove on the control column rotates to the corresponding position, the sealing bead no longer contacts the edge of the side wall of the control column, the compression spring recovers its deformation, the limit plate breaks through the limit spring sheet, the sealing bead contacts the groove on the control column, and the overheated air enters the ventilation duct from the orifice plate and is discharged to the outside. At the same time, the control column continues to rotate, so that the adjacent grooves evenly distributed in the spiral contact the adjacent sealing beads, and the adjacent orifice plates are no longer sealed. At this time, the box body is in a negative pressure state because of a large amount of exhaust gas, and the external normal temperature air is supplemented into the box body along the adjacent orifice plates. The present invention can automatically detect the internal temperature of the explosion-proof electric box. When the battery pack is abnormally heated, the temperature-increasing area is actively exhausted and depressurized to compensate for the external normal temperature air, and the battery pack is cooled. When the weather is cold, the battery pack is subjected to regional temperature heating thermal compensation, so that the battery is at the temperature of the best electrochemical conversion, and the working efficiency of the battery is guaranteed.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] like Figure 1 As shown, the present invention provides a technical solution of an explosion-proof solar street lamp with an automatic detection function. The street lamp comprises a lamp holder 1, a lamp pole 2, a rotating frame 3, a photovoltaic panel 4, a lamp group 5, a mounting frame 6 and an explosion-proof electric box 7. The lamp pole 2 is fixedly connected to the lamp holder 1, the rotating frame 3, the lamp group 5 and the mounting frame 6. The photovoltaic panel 4 is hinged to the rotating frame 3, the explosion-proof electric box 7 is fixedly connected to the mounting frame 6, the explosion-proof electric box 7 is connected to the photovoltaic panel 4 through electric wires, and the explosion-proof electric box 7 is connected to the lamp group 5 through electric wires.
[0026] The present invention is a method of utilizing a photovoltaic panel 4 to convert solar energy into electrical energy, and storing the electrical energy in an explosion-proof electrical box 7. The explosion-proof electrical box 7 supplies power to a lamp group 5. When the explosion-proof electrical box 7 transmits electrical energy, the internal battery will generate heat energy. The heat energy accumulates in the explosion-proof electrical box 7, which will cause the battery to explode and spontaneously combust, causing danger. When storing and releasing electrical energy, the explosion-proof electrical box 7 automatically detects the temperature rise of different internal areas, exhausts and dissipates heat in the temperature rise area, and releases pressure to avoid explosion. When the weather is cold and the temperature is low, the efficiency of the battery in converting electrical energy decreases. The internal area below the optimal discharge temperature is detected, and local temperature compensation is performed to keep the battery at a temperature with optimal electrical energy conversion efficiency.
[0027] like Figure 2 , Figure 4 As shown, the explosion-proof electrical box 7 includes a box body 71, a battery pack 72, a detection mechanism 73 and a pressure relief mechanism 74. The box body 71 is fixedly connected to the mounting frame 6. Two groups of first through holes 711 are provided on the box body 71. One group of first through holes 711 is connected to the photovoltaic panel 4 through wires, and the other group of first through holes 711 is connected to the lamp group 5 through wires. The battery pack 72 is connected to the photovoltaic panel 4 and the lamp group 5 through wires. The battery pack 72 and the pressure relief mechanism 74 are both fixedly connected to the box body 71. A plurality of groups of thermal conductive copper plates 721 are provided on the battery pack 72. The plurality of groups of thermal conductive copper plates 721 are linearly evenly distributed on the side walls of the battery pack 72 in the vertical direction. The detection mechanism 73 is in contact with the thermal conductive copper plates 721. Two groups of pressure relief mechanisms 74 are provided. The two groups of pressure relief mechanisms 74 are located on both sides of the battery pack 72. The detection mechanism 73 is connected to the pressure relief mechanism 74 through electrical signals.
[0028] The battery pack 72 is divided into several groups of heat dissipation zones arranged equally by linearly distributing several groups of heat-conducting copper plates 721 on the side walls of the battery pack 72. The temperature of the battery pack 72 is transmitted to the detection mechanism 73 by the heat-conducting copper plates 721. The detection mechanism 73 detects the temperature rise of the battery pack 72 corresponding to the temperature rise area of the heat-conducting copper plates 721, and transmits an electrical signal to the pressure relief mechanisms 74 on both sides. The pressure relief mechanisms 74 open the vents at the corresponding positions, discharge the internal heated gas to the outside of the box 71 and relieve the pressure at the same time. When the detection mechanism 73 detects that the battery pack 72 is lower than the optimal discharge temperature, local temperature compensation is performed to bring the battery to a temperature with optimal electric energy conversion efficiency.
[0029] like Figure 3As shown, the detection mechanism 73 includes a first base frame 731, a first motor 732, a first worm 733, a worm seat 734, a slide 735, a thermal resistance mechanism 736 and a compensation mechanism 737. The first base frame 731 is fixedly connected to the box body 71 and the first motor 732. The output end of the first motor 732 is fixedly connected to the first worm 733. The worm seat 734 is provided with a threaded hole 7341 and a second through hole 7342. The first worm 733 is connected to the threaded hole 7341 by threads. The slide 735 is fixedly connected to the battery pack 72. The worm seat 734 is slidably connected to the slide 735. The second through hole 7342 is fixedly connected to the thermal resistance mechanism 736. The thermal resistance mechanism 736 is in contact with the temperature-conducting copper plate 721. The thermal resistance mechanism 736 is fixedly connected to the compensation mechanism 737. The thermal resistance mechanism 736 is connected to the compensation mechanism 737 and the pressure relief mechanism 74 are all connected by electrical signals.
[0030] The temperature of the battery pack 72 is transmitted to the thermal resistance mechanism 736 by the thermal conductive copper plate 721, and the first motor 732 outputs torque to the first worm 733. The first worm 733 is threadedly connected to the threaded hole 7341 on the worm seat 734, and the rotation of the first worm 733 is converted into the reciprocating sliding of the worm seat 734 along the slide 735. The worm seat 734 drives the thermal resistance mechanism 736 to slide along the thermal conductive copper plate 721. The heating conditions of different areas on the thermal conductive copper plate 721 are detected by the sliding of the thermal resistance mechanism 736. The thermal resistance mechanism 736 transmits electrical signals to the pressure relief mechanisms 74 on both sides. When the weather is cold and the temperature is low, the compensation mechanism 737 actively generates heat to the thermal resistance mechanism 736, so that the thermal resistance mechanism 736 is raised to the optimal discharge temperature. The thermal resistance mechanism 736 detects the area where the temperature of the thermal conductive copper plate 721 is lower than the optimal discharge temperature. The compensation mechanism 737 adjusts the heating position to perform precise temperature rise thermal compensation on the back of the battery pack 72.
[0031] like Figure 4 As shown, the thermal resistance mechanism 736 includes a loop pipe 7361, an electrode clamp 7362, an ammeter 7363 and a mounting plate 7364. The loop pipe 7361 is fixedly connected to the second through hole 7342 and the compensation mechanism 737. The electrode clamp 7362 and the ammeter 7363 are provided in several groups. Several groups of electrode clamps 7362 are in contact with the temperature conductive copper plate 721. The mounting plate 7364 is fixedly connected to the electrode clamp 7362 and the ammeter 7363. The ammeter 7363 is connected to the compensation mechanism 737 and the pressure relief mechanism 74 through electrical signals.
[0032] When the temperature of the thermal conductive copper plate 721 rises due to the battery pack 72, there is a temperature difference between the electrode clamp 7362 and the thermal conductive copper plate 721. The temperature difference between the two different conductors generates current, and a number of vertically arranged groups of ammeters 7363 slide horizontally along the thermal conductive copper plate 721 to various areas. The heating area of the battery pack 72 is obtained by superimposing the two-axis coordinates. When the compensation mechanism 737 actively generates heat, the heat is transferred to the electrode clamp 7362 through the loop pipe 7361, so that there is a temperature difference between the electrode clamp 7362 and the thermal conductive copper plate 721.
[0033] like Figure 5 As shown, the compensation mechanism 737 includes a base plate 7371, a second motor 7372, a bevel gear set 7373, a second worm 7374 and a thermal resistor ring 7375. The base plate 7371 is fixedly connected to the loop pipe 7361 and the second motor 7372. The loop pipe 7361 is provided with a third through hole 73611 and a slide rail 73612. The output end of the second motor 7372 is rotationally connected to the third through hole 73611. The bevel gear set 7373 is transmission-connected to the output end of the second motor 7372 and the second worm 7374. The thermal resistor ring 7375 is provided with an inner wall thread 73751. The second worm 7374 is threadedly connected to the inner wall thread 73751. The thermal resistor ring 7375 is slidably connected to the slide rail 73612. The second motor 7372 and the thermal resistor ring 7375 are connected to the ammeter 7363 through electrical signals.
[0034] When the weather is cold and the temperature is low, the thermal resistor coil 7375 heats the gas in the loop pipe 7361 to provide heat for the electrode clamp 7362. When the ammeter 7363 obtains the coordinates of the area where the battery pack 72 heats up slowly, it sends an electrical signal to the second motor 7372. The second motor 7372 outputs torque to the bevel gear set 7373. The bevel gear set 7373 changes the torque to make the second worm 7374 rotate around its axis. Through the threaded connection between the second worm 7374 and the inner wall thread 73751 on the thermal resistor coil 7375, the rotation of the second worm 7374 is converted into the thermal resistor coil 7375 moving up and down along the slide rail 73612. The thermal resistor coil 7375 is moved to the area where the battery pack 72 heats up slowly. The heat of the thermal resistor coil 7375 itself is transferred through the loop pipe 7361 to perform temperature compensation on this area.
[0035] like Figure 6 , Figure 8As shown, the pressure relief mechanism 74 includes a housing 741, a cylinder 742, a hinged connecting rod 743, a top plate 744, a baffle 745, a grille 746, a switch mechanism 747 and an exhaust mechanism 748. The housing 741 is fixedly connected to the box body 71, the cylinder 742, the grille 746 and the switch mechanism 747. The output end of the cylinder 742 is hinged to the hinged connecting rod 743. A convex column 7441 is provided on the top plate 744. The hinged connecting rod 743 is away from the cylinder 74. One end is rotatably connected to the boss 7441, the baffle 745 is fixedly connected to the top plate 744, the baffle 745 is rotatably connected to the housing 741, a plurality of ventilation ducts 7411 are provided on the housing 741, the plurality of ventilation ducts 7411 are linearly evenly distributed along the side wall of the housing 741, the ventilation ducts 7411 are fixedly connected to the exhaust mechanism 748, the switch mechanism 747 contacts the exhaust mechanism 748, and the switch mechanism 747 is connected to the ammeter 7363 through an electrical signal.
[0036] The cylinder 742 reciprocates to push the hinged connecting rod 743, and through the rotation connection between the hinged connecting rod 743 and the boss 7441 on the top plate 744, the baffle 745 is driven to rotate around its axis. The baffle 745 reciprocates to connect the spaces on both sides. When the ammeter 7363 obtains the coordinates of the abnormally heated area of the battery pack 72, an electrical signal is generated to the switch mechanism 747. The switch mechanism 747 opens the exhaust mechanism 748 at the corresponding position. When the exhaust mechanism 748 at the corresponding position rotates to connect the two sides of the baffle 745, the overheated air at the corresponding position in the box body 71 is discharged and the pressure is relieved, and the exhaust mechanism 748 at other positions is used to replenish normal temperature gas into the box body 71 to cool the battery pack 72.
[0037] like Figure 7 , Figure 8 As shown, the switch mechanism 747 includes a second base frame 7471, a third motor 7472 and a control column 7473. The second base frame 7471 is fixedly connected to the third motor 7472 and the housing 741. The third motor 7472 is connected to the ammeter 7363 through an electrical signal. The output end of the third motor 7472 is fixedly connected to the control column 7473. The control column 7473 is in contact with the exhaust mechanism 748. A plurality of groups of grooves 74731 are provided on the control column 7473. The plurality of groups of grooves 74731 are arranged on the side wall of the control column 7473 and are evenly distributed in a spiral along the axis.
[0038] The third motor 7472 outputs torque to the control column 7473 according to the electrical signal sent by the ammeter 7363, driving the control column 7473 to rotate. When the edge of the side wall of the control column 7473 contacts the exhaust mechanism 748, the exhaust mechanism 748 is sealed and does not transmit overheated air. When the groove 74731 on the control column 7473 contacts the exhaust mechanism 748, the exhaust mechanism 748 at the corresponding position opens, and the pressure of the gas inside the box 71 increases due to the heating and expansion of the battery pack 72, and is discharged to the outside through the opened exhaust mechanism 748. At the same time, the control column 7473 continues to rotate, so that the adjacent grooves 74731 evenly distributed in the spiral contact the adjacent exhaust mechanism 748, and the adjacent exhaust mechanism 748 opens. At this time, the box 71 is in a negative pressure state because a large amount of exhaust has just been discharged, and the external normal temperature air is replenished into the inside of the box 71 along the adjacent exhaust mechanism 748.
[0039] like Figure 8 , Fig. 9 As shown, the exhaust mechanism 748 includes a hole frame 7481, a connecting column 7482, a sealing bead 7483, a limiting plate 7484, a limiting spring 7485, a compression spring 7486, a cross frame 7487 and a hole plate 7488. The hole frame 7481, the limiting spring 7485, the cross frame 7487 and the hole plate 7488 are all fixedly connected to the ventilation duct 7411, the connecting column 7482 is slidably connected to the hole frame 7481, the sealing bead 7483, the limiting plate 7484 and the compression spring 7486 are all fixedly connected to the connecting column 7482, and the compression spring 7486 is fixedly connected to the cross frame 7487.
[0040] When the edge of the side wall of the control column 7473 contacts the sealing bead 7483, the connecting column 7482 is pushed to slide along the hole frame 7481 toward the direction close to the cross frame 7487, the limiting plate 7484 on the connecting column 7482 breaks through the limiting spring piece 7485, and the sealing bead 7483 contacts the hole plate 7488 to achieve a sealing effect; when the groove 74731 on the control column 7473 rotates to the corresponding position, the sealing bead 7483 no longer contacts the edge of the side wall of the control column 7473; under the action of the compression spring 7486 restoring the deformation, the limiting plate 7484 breaks through the limiting spring piece 7485 toward the direction away from the cross frame 7487, the sealing bead 7483 contacts the groove 74731 on the control column 7473, and the superheated air enters the ventilation duct 7411 through the hole plate 7488.
[0041] Working principle of the present invention: The present invention is a method of converting solar energy into electrical energy by using photovoltaic panels 4. The batteries inside the explosion-proof electrical box 7 will generate heat accumulation, which may cause the batteries to explode and self-ignite, causing danger. The battery pack 72 is divided into several groups of heat dissipation zones arranged in equal parts by a plurality of groups of heat-conducting copper plates 721 linearly evenly distributed on the side walls of the battery pack 72. The temperature of the battery pack 72 is transferred from the heat-conducting copper plates 721 to the electrode clamp 7362. There is a temperature difference between the electrode clamp 7362 and the heat-conducting copper plates 721. There is a temperature difference between the two different conductors. The difference generates current, and the multiple groups of ammeters 7363 arranged vertically slide horizontally along the temperature-conducting copper plate 721 to various areas. The heating area of the battery pack 72 is obtained by superimposing the two-axis coordinates. The cylinder 742 reciprocates to push the hinged connecting rod 743, driving the baffle 745 to rotate around its axis. The baffle 745 reciprocates to connect the spaces on both sides. The third motor 7472 outputs torque to the control column 7473 according to the electrical signal sent by the ammeter 7363, driving the control column 7473 to rotate. When the groove 74 on the control column 7473 is 731 rotates to the corresponding position, the sealing bead 7483 no longer contacts the edge of the side wall of the control column 7473, and under the action of the compression spring 7486 restoring the deformation, the limit plate 7484 breaks through the limit spring 7485 in the direction away from the cross frame 7487, and the sealing bead 7483 contacts the groove 74731 on the control column 7473, and the superheated air enters the ventilation duct 7411 through the orifice plate 7488. At the same time, the control column 7473 continues to rotate, so that the adjacent grooves 74731 evenly distributed in the spiral contact the adjacent exhaust mechanism 748, and the adjacent exhaust mechanism 748 is closed. The air mechanism 748 is opened, and the box body 71 is in a negative pressure state because a large amount of exhaust has just been discharged. The external normal temperature air is replenished into the box body 71 along the adjacent exhaust mechanism 748. When the explosion-proof electric box 7 stores and releases electric energy, it automatically detects the temperature rise of different internal areas, exhausts and dissipates heat in the temperature rise areas, and releases pressure to avoid explosion. When the weather is cold and the temperature is low, the efficiency of battery conversion of electric energy decreases. The internal area below the optimal discharge temperature is detected, and local temperature compensation is performed to keep the battery at a temperature with optimal electric energy conversion efficiency.
