[0019] The beneficial effects of the present invention are:

[0020] 1. Monitor the surrounding environment through the sensor control mechanism. Under normal conditions, the protection control mechanism controls the two sets of self-adjusting protection mechanisms to unfold and merge at the top to block rain and sunlight for the power supply device. When the sensor control mechanism monitors that there are objects around the power supply device and they are gradually approaching the power supply device, it will send a signal to the protection control mechanism. The protection control mechanism will immediately control the two sets of self-adjusting protection mechanisms to unfold to both sides, wrapping the distribution box in all directions to form collision protection, so that the power supply device can autonomously adjust the protection part according to the surrounding environment, thereby improving the protection performance of the power supply device.

[0021] 2. The light intensity is monitored by a sensor control mechanism. When the light is sufficient, several groups of first electric push rods are controlled to drive the translation plate to move horizontally, so that several groups of solar cells enter several groups of wide-mouth light-passing grooves. Several groups of solar cells are arranged in parallel and can continue to work when one or more groups of solar cells are damaged. Several groups of solar cells convert solar energy into electrical energy and store it in the protection control mechanism, so that when the power supply of the power supply device is cut off, the protection control mechanism can still control the self-adjusting protection mechanism to perform protection work, thereby improving the use effect of the power supply device.

[0022] 3. By installing an insulating heat insulation board in the installation room, the insulating heat insulation board divides the installation room into two spaces, and then installing the main switch on the insulating heat insulation board, the main switch and the distribution box are set without contact. This not only can prevent the main switch from being affected when a fault occurs in the connected line and catches fire, but also can prevent overvoltage from being damaged by the distribution box during lightning strikes. At the same time, when a certain connected line continues to heat up, the corresponding guide column will drop to disconnect the connecting column from the main switch, avoiding fire caused by continuous heating of the connected line, thereby improving the safety of the power supply device.

[0023] 4. Monitor the water height on the ground through the liquid level sensor, and then control the four groups of first motors to drive the four groups of first screws to rotate. Since the bottom of the first screw is rotatably connected to the top of the installation base plate and is threadedly connected to the distribution box, when the first screw rotates, the four groups of lifting plates will drive the four groups of first screws to descend, and the distribution box will rise until it reaches a safe height, avoiding excessive water accumulation on the ground and seeping into the distribution box to cause a short circuit in the line, thereby improving the waterproof performance of the power supply device.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0039] The embodiment of the present invention provides a self-adjusting protection type unattended power supply device, including a distribution box 1. For example, Figure 1 , Figure 2 and Figure 3 As shown, a mounting base plate 2 is provided at the bottom of the distribution box 1; a mounting chamber 6 is provided in the distribution box 1; a protection control mechanism 7 is provided on one inner wall of the mounting chamber 6; two groups of self-adjusting protection mechanisms 3 are symmetrically connected to the output end of the protection control mechanism 7; a sensing control mechanism 4 is movably penetrated through the top of the distribution box 1; a liquid level sensor 5 is provided on one side wall of the distribution box 1; a wiring installation mechanism 8 is provided in the mounting chamber 6; a main switch 9 is provided on the top of the wiring installation mechanism 8; four groups of first slide grooves 10 are symmetrically provided on the inner walls on both sides of the mounting chamber 6; a group of lifting plates 11 are slidably connected in each group of the first slide grooves 10; a group of first motors 12 are provided on the top of each group of the lifting plates 11; the output end of each group of the first motors 12 extends to the bottom of the lifting plate 11, and is connected to a group of first screw rods 13 in transmission; each group of the first screw rods 13 is movably penetrated in the wiring installation mechanism 8; the bottom end of each group of the first screw rods 13 is rotatably connected to the top of the mounting base plate 2.

[0040] When the power supply device is working, the sensor control mechanism 4 monitors the surrounding environment of the power supply device. Under normal conditions, the protection control mechanism 7 controls the two sets of self-adjusting protection mechanisms 3 to unfold and merge at the top, thereby forming an effect of blocking rain and direct sunlight for the distribution box 1. When the sensor control mechanism 4 monitors that there are objects moving around the power supply device and gradually approaching the power supply device, it will send a signal to the protection control mechanism 7. The protection control mechanism 7 will immediately control the two sets of self-adjusting protection mechanisms 3 to unfold to both sides, wrapping the distribution box 1 in all directions to form collision protection, so that the power supply device can autonomously adjust the protection part according to the surrounding environment, thereby improving the protection performance of the power supply device. When the power supply device is in rainy weather for a long time and there is a lot of water on the ground, the liquid level sensor 5 can monitor the height of the water on the ground, and then control the four groups of first motors 12 to drive the four groups of first screw rods 13 to rotate. Since the bottom of the first screw rod 13 is rotatably connected to the top of the mounting base 2 and is threadedly connected to the distribution box 1, when the first screw rod 13 rotates, the four groups of lifting plates 11 will drive the four groups of first screw rods 13 to descend, and the distribution box 1 will rise until it reaches a safe height, avoiding excessive water on the ground from seeping into the distribution box 1 and causing a short circuit in the line, thereby improving the waterproof performance of the power supply device.

[0041] For example, Figure 4 and Figure 5As shown, the self-adjusting protective mechanism 3 includes a first protective plate 301; two groups of second protective plates 302 are symmetrically arranged on the two side walls of the first protective plate 301; two groups of second motors 303 are symmetrically arranged at the two side edges of one side wall of the first protective plate 301; the output end of each group of the second motors 303 is transmission-connected with a corresponding group of second protective plates 302; a light-through hole 304 is opened on a side wall of the first protective plate 301 away from the second motor 303; a light-transmitting glass plate is arranged in the light-through hole 304; the internal structure of the second protective plate 302 is the same as that of the first protective plate 301; a translation cavity 306 is arranged in the first protective plate 301; the translation cavity 306 A plurality of groups of wide-mouth light-transmitting slots 305 are arranged in a rectangular array on the inner wall of the cavity 306 away from the distribution box 1; a translation plate 307 is slidably connected in the translation cavity 306; a plurality of groups of solar cells 308 are arranged in a rectangular array on the wall of the translation plate 307 close to the wide-mouth light-transmitting slots 305; the plurality of groups of solar cells 308 are arranged in parallel and are electrically connected to the protection control mechanism 7; each group of solar cells 308 is movable through a corresponding group of wide-mouth light-transmitting slots 305; a plurality of groups of first electric push rods 309 are arranged on the inner wall of one side of the translation cavity 306; the output ends of the plurality of groups of the first electric push rods 309 are transmission-connected to the translation plate 307.

[0042] When the power supply device is working, the sensor control mechanism 4 monitors the light intensity of the external environment. When the light is sufficient, the sensor control mechanism 4 controls several groups of first electric push rods 309 to drive the translation plate 307 to move horizontally, so that several groups of solar cells 308 enter several groups of wide-mouth light-through grooves 305. The wide-mouth light-through grooves 305 can not only prevent large foreign objects from directly colliding with the solar cells 308, but also facilitate sunlight to illuminate the solar cells 308, and can facilitate the drainage of accumulated water after blocking rain and water. Several groups of solar cells 308 are arranged in parallel and can continue to work when one or more groups of solar cells 308 are damaged. Several groups of solar cells 308 convert solar energy into electrical energy and store it in the protection control mechanism 7, so that when the power supply of the power supply device is cut off, the protection control mechanism 7 can still control the self-adjusting protection mechanism 3 to perform protection work, thereby improving the use effect of the power supply device.

[0043] For example, Figure 6 As shown, the sensor control mechanism 4 includes a telescopic column 401; a photosensitive module 402 is provided on the top of the telescopic column 401; a mounting groove 403 is opened on the side wall of the telescopic column 401; the top view interface of the mounting groove 403 is annular; and a plurality of groups of infrared cameras 404 are distributed in a circular array on the inner wall of the mounting groove 403.

[0044] The photosensitive module 402 is used to monitor the light intensity of the environment in which the power supply device is located. Several groups of infrared cameras 404 are used to monitor moving objects within a 360° range of the power supply device and can send signals to control the self-adjusting protection mechanism 3 to adjust the protection state according to environmental conditions.

[0045] For example, Figure 7 and Figure 8 As shown, the protection control mechanism 7 includes a shell 701; a rotating disk 702 is provided on a side wall of the shell 701 away from the installation chamber 6; each group of the rotating disks 702 are transmission-connected to a plurality of second electric push rods 703 on a side wall away from the shell 701; a plurality of second electric push rods 703 on the same side are transmission-connected to a corresponding group of self-adjusting protection mechanisms 3; a power cavity 704 is provided in the shell 701; two groups of third motors 705 are provided on the inner wall of the power cavity 704 on a side close to the rotating disk 702; each group of the third motors 705 is transmission-connected to a corresponding group of rotating disks 702; an energy storage battery 706 is provided in the power cavity 704; the energy storage battery 706 is electrically connected to the self-adjusting protection mechanism 3, the two groups of third motors 705, the four groups of first motors 12 and the sensor control mechanism 4.

[0046] The energy storage battery 706 is charged through the self-adjusting protection mechanism 3, and then supplies power to the self-adjusting protection mechanism 3, two groups of third motors 705, four groups of first motors 12 and the sensor control mechanism 4, so that when the access power supply of the power supply device is cut off, the power supply device can still perform self-adjustment work for protection and waterproofing.

[0047] For example, Fig. 9 , Fig.10 and Fig.11As shown, the installation wiring mechanism 8 includes an insulating heat-insulating plate 801; the two ends of the insulating heat-insulating plate 801 are respectively connected to the inner walls of the two sides of the installation chamber 6; the insulating heat-insulating plate 801 is distributed in a rectangular array and is movably penetrated by a plurality of groups of guide pillars 805; the top of each group of the guide pillars 805 extends to the top of the insulating heat-insulating plate 801, and is provided with a group of connecting pillars 807; the bottom of each group of the guide pillars 805 extends to the bottom of the insulating heat-insulating plate 801, and is provided with a group of connecting terminals 807. 6; each group of the wiring terminals 806 is provided with a separate number; each group of the connecting posts 807 is electrically connected to a corresponding group of the wiring terminals 806, and is electrically connected to the main switch 9; a group of third electric push rods 808 are provided on one side wall of each group of the guide posts 805; a group of insulating collars 809 are provided on the output end of each group of the third electric push rods 808; each group of the insulating collars 809 is sleeved on the outer wall of the corresponding group of the guide posts 805; the insulating heat insulation board 801 Two groups of second slide grooves 802 are symmetrically opened at the edges of both sides of the top; each group of the second slide grooves 802 is slidably connected with a group of limit plates 803; each group of the limit plates 803 is movable and penetrates the outer walls of both sides of the switch main switch 9; an adjustment cavity 810 is provided in the insulating and heat-insulating plate 801; two groups of second screw rods 811 are provided in the adjustment cavity 810; one end of the two groups of the second screw rods 811 is fixedly connected, and the other end is rotatably connected to the inner walls of both sides of the adjustment cavity 810; the two groups of the second The thread directions of the screw rod 811 are opposite, and the central axes are on the same straight line; the two groups of the second screw rods 811 are respectively threadedly connected to a group of limit plates 803; a first bevel gear 812 is sleeved on the outer wall of one group of the second screw rods 811; the top damping rotation of the insulating and heat-insulating plate 801 is connected to a knob 804; one end of the knob 804 extends into the adjusting cavity 810, and is transmission-connected to a second bevel gear 813; the second bevel gear 813 is meshingly connected to the first bevel gear 812.

[0048] By setting an insulating heat insulation board 801 in the installation room 6, the insulating heat insulation board 801 divides the installation room 6 into two upper and lower spaces, and then installing the main switch 9 on the insulating heat insulation board 801, the main switch 9 and the distribution box 1 are set without contact. This can not only prevent the fire from affecting the main switch 9 when a fault occurs in the connected line and a fire occurs, but also prevent the overvoltage from damaging the main switch 9 through the distribution box 1 during a lightning strike. When a certain connected line continues to heat up, the corresponding third electric push rod 808 will drive the corresponding guide column 805 to descend, so that the connecting column 807 is disconnected from the main switch 9, thereby preventing the connected line from continuing to heat up and causing a fire. The wiring terminals 806 with separate numbers also facilitate maintenance work for personnel, thereby improving the safety of the power supply device. When the main switch 9 fails and needs maintenance, the second bevel gear 813 is driven to rotate by turning the knob 804. Under the meshing connection relationship between the second bevel gear 813 and the first bevel gear 812, the second bevel gear 813 drives the two sets of second screw rods 811 to rotate. Under the threaded connection relationship between the two sets of second screw rods 811 and the two sets of limit plates 803, the two sets of limit plates 803 move toward the side away from the main switch 9 and thus detach from the outer wall of the main switch 9. The process is simple and quick, which improves the maintenance convenience of the power supply device.

[0049] The surrounding environment is monitored by the sensor control mechanism 4. Under normal conditions, the protection control mechanism 7 controls the two groups of self-adjusting protection mechanisms 3 to unfold and merge at the top to block rain and sunlight for the power supply device. When the sensor control mechanism 4 detects that there are objects moving around the power supply device and gradually approaching the power supply device, it will send a signal to the protection control mechanism 7. The protection control mechanism 7 will immediately control the two groups of self-adjusting protection mechanisms 3 to unfold to both sides, wrapping the distribution box 1 in all directions to form collision protection, so that the power supply device can autonomously adjust the protection part according to the surrounding environment, thereby improving the protection performance of the power supply device.

[0050] The light intensity is monitored by the sensor control mechanism 4. When the light is sufficient, several groups of first electric push rods 309 are controlled to drive the translation plate 307 to move horizontally, so that several groups of solar cells 308 enter several groups of wide-mouth light-passing grooves 305. Several groups of solar cells 308 are arranged in parallel and can continue to work when one or more groups of solar cells 308 are damaged. Several groups of solar cells 308 convert solar energy into electrical energy and store it in the protection control mechanism 7, so that when the power supply of the power supply device is cut off, the protection control mechanism 7 can still control the self-adjusting protection mechanism 3 to perform protection work, thereby improving the use effect of the power supply device.

[0051] By setting an insulating heat-insulating plate 801 in the installation room 6, the insulating heat-insulating plate 801 divides the installation room 6 into two upper and lower spaces, and then installing the main switch 9 on the insulating heat-insulating plate 801, the main switch 9 and the distribution box 1 are set without contact. Not only can the main switch 9 not be affected when a fault occurs in the connected line and catches fire, but also the overvoltage during lightning strikes can be prevented from damaging the main switch 9 through the distribution box 1. At the same time, when a certain connected line continues to heat up, the corresponding guide column 805 will descend to disconnect the connecting column 807 from the main switch 9, thereby preventing the connected line from continuing to heat up and causing fire, thereby improving the safety of the power supply device.

[0052] The liquid level sensor 5 is used to monitor the water height on the ground, and then the four groups of first motors 12 are controlled to drive the four groups of first screw rods 13 to rotate. Since the bottom of the first screw rod 13 is rotatably connected to the top of the mounting base plate 2 and is threadedly connected to the distribution box 1, when the first screw rod 13 rotates, the four groups of lifting plates 11 will drive the four groups of first screw rods 13 to descend, and the distribution box 1 will rise until it reaches a safe height, thereby preventing excessive water from seeping into the distribution box 1 and causing a short circuit in the line, thereby improving the waterproof performance of the power supply device.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
