[0001] The utility model relates to the field of distributed power supplies, and in particular to a combined distributed power supply for a smart park. Background Art

[0002] Distributed power sources generally refer to power sources installed near users, connected to power grids at voltage levels of 35kV and below, and mainly consumed locally. They include solar energy, natural gas, biomass energy, wind energy and other types. Distributed power sources can be used to meet specific requirements of power systems and users, such as peak load regulation, power supply to remote users or commercial and residential areas, saving investment in transmission and transformation, and improving power supply reliability.

[0003] For example, distributed power sources using solar energy are often installed on the roofs of buildings. When electricity consumption is low, solar panels are used to charge batteries and store electricity. When electricity consumption is high, they can be used to supply electricity. Most common solar panels are directly fixed and installed at a fixed angle. As the sun moves, the solar panels can receive less sunlight in a day, so the efficiency is not high. Summary of the invention

A traction rod is also arranged on the outer side of the power cabinet body, and the traction rod passes through the baffle, and a baffle is arranged on the traction rod. A lifting ring is connected to the upper end of the traction rod, and a hook is fixedly connected to the side wall of the power cabinet body.

[0022] Through the above technical solution, when the angle of the adjustment block changes, the heights of the two movable support rods on both sides are inconsistent, so the solar panel will tilt, that is, the angle will change.

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0037] Please combine Figure 1 and Figure 2 A combined distributed power supply for a smart park in this embodiment includes a power cabinet body 1, and a partition 2 is fixedly installed inside the power cabinet body 1, wherein the partition 2 divides the internal space of the power cabinet body 1 into three layers, namely, an upper, middle and lower layer, from top to bottom, which are a control layer 101, a device layer 102 and a heat dissipation layer 103, wherein the partition 2 is provided with an inner heat dissipation hole 201, and the top of the power cabinet body 1 (the top of the control layer 101) is also provided with a heat dissipation hole.

[0038] A solar panel 3 is arranged on the top of the power cabinet body 1 , and a movable support rod 4 is rotatably connected to the back of the solar panel 3 . The lower end of the movable support rod 4 passes through the top of the power cabinet body 1 and enters the control layer 101 .

[0039] Please combine Figure 3 and Figure 4 An angle control mechanism 5 is provided in the control layer 101, and the lower end of the movable support rod 4 is connected to the angle control mechanism 5 for adjusting the angle of the solar panel 3, so that the solar panel 3 can receive light for a longer time.

[0040] Specifically, the angle control mechanism 5 includes an adjustment shaft 501 and an adjustment block 502. First, both ends of the adjustment shaft 501 are rotatably installed in the control layer 101 through a bearing seat, and the adjustment block 502 is connected to the outer sleeve of the adjustment shaft 501, that is, the adjustment shaft 501 passes through the adjustment block 502 as a whole;

[0041] At the same time, a gear 503 is fixedly connected on the adjusting shaft 501 and located on both sides of the adjusting block 502, and a toothed plate 504 is meshingly connected below the gear 503. At the same time, a limiting groove is opened on the corresponding partition 2 below the toothed plate 504, and the toothed plate 504 is also slidably installed in the limiting groove.

[0042] In addition, a slider 505 and a threaded rod 506 are also provided in the control layer 101. The slider 505 is located below the adjustment block 502, and the side of the slider 505 is fixedly connected to the toothed plate 504. A threaded hole is opened on the slider 505, and the threaded rod 506 runs through the slider 505 as a whole. One end of the threaded rod 506 is connected to a motor.

[0043] The movable support rod 4 is in a "U" shape as a whole. At the same time, an oblong through hole (not marked in the figure) is opened on the top of the power cabinet body 1. The movable support rod 4 passes through the oblong through hole, and its lower end enters the control layer 101. At the same time, a through hole is opened on the adjustment block 502 in the angle adjustment structure. The lower end of the movable support rod 4 passes through the adjustment block 502 as a whole, and the movable support rod 4 is rotatably connected to the adjustment block 502.

[0044] In order to facilitate the rotation of the solar panel 3, a fixed support rod 15 is also fixedly connected to the top of the power cabinet body 1, and the upper end of the fixed support rod 15 is rotatably connected to the bottom surface of the solar panel 3, so that the solar panel 3 can rotate around the connection point with the fixed support rod 15.

[0045] In summary, when the motor drives the threaded rod 506 to rotate, it can drive the slider 505 and the toothed plate 504 to move. When the toothed plate 504 moves, it will drive the gear 503, the adjusting shaft 501 and the adjusting block 502 to rotate together.

[0046] Replay Figure 2 At this time, the solar panel 3 is in a horizontal state. When the adjustment block 502 rotates, a height difference will occur at both ends. The movable support rod 4 at one end moves downward, and the movable support rod 4 at the other end moves upward.

[0047] When there is a height difference between the two movable support rods 4, the angle of the solar panel 3 will change from a horizontal state to an inclined state. By changing the moving distance of the tooth plate 504, the rotation angle of the adjustment block 502 can be controlled, and thus the inclination angle of the solar panel 3 can also be controlled, so that it can always maintain a state of receiving sunlight and extend its power generation working time.

[0048] In order to store the electricity generated by the solar panel 3, a battery 6 and a voltage regulator 7 are installed in the equipment layer 102, wherein the battery 6 is electrically connected to the voltage regulator 7, the voltage regulator 7 is electrically connected to the solar panel 3, and the voltage regulator 7 is adapted to the battery 6 voltage to ensure that the solar panel 3 can have a stable voltage to charge the battery 6, and the battery 6 can discharge when electricity is needed.

[0049] Because the device can be installed near the user, that is, during the period of low electricity consumption, the solar panel 3 is used to charge the battery 6, and during the peak period of electricity consumption, it supplies power to the outside. Because it is installed near the user, the distance is short, the power transmission loss is small, and it can be reasonably allocated according to the electricity demand to meet different needs.

[0050] Since the voltage stabilizer 7, the battery 6 and other supporting electrical equipment generate a lot of heat when working, in order to speed up the heat dissipation, first of all, as mentioned above, the partition 2 is provided with an inner heat dissipation hole 201, and the top of the power cabinet body 1 (the top of the control layer 101) is also provided with a heat dissipation hole, and the hot air flows upward, which is convenient and fast to dissipate heat. At the same time, the outer wall of the equipment layer 102 that generates the most heat is also provided with an outer heat dissipation hole 9 to help dissipate heat.

[0051] In addition, a cooling fan 8 is installed in the heat dissipation layer 103. The cooling fan 8 is driven by a motor. The cooling fan 8 is located at the bottom. The airflow it blows upward will pass through the partition 2, pass through the equipment layer 102 and the control layer 101 in turn, and finally blow out from the top of the power cabinet body 1.

[0052] Please combine Figure 5 and Figure 6 In hot seasons, heat dissipation is more important, but in winter, especially in snowy weather, ice and snow may fall on the solar panel 3. On the one hand, it hinders the work of the solar panel 3. On the other hand, the ice and snow will increase the weight of the solar panel 3, increase the burden on the movable support rod 4 and the fixed support rod 15, and even have the risk of damage.

[0053] Based on this, a baffle 10 is also rotatably mounted on the outer wall of the equipment layer 102, that is, mounting seats (not marked in the figure) are arranged on both sides of the baffle 10, and the baffle 10 is rotatably connected to the mounting seats. The baffle 10 is located above the above-mentioned external heat dissipation holes 9, and also has the function of preventing debris and rainwater from entering the equipment layer 102 through the external heat dissipation holes 9;

[0054] At the same time, a traction rod 11 is also provided on the outside of the power cabinet body 1, and the traction rod 11 passes through the baffle 10, and a baffle 12 is provided on the traction rod 11, and each baffle 10 corresponds to a baffle 12, so when the traction rod 11 is pulled upward, the baffle 10 will rotate under the action of the baffle 12, and after the rotation, Figure 6 When the traction rod 11 is downward, the baffle 10 falls down under the action of gravity and covers the outer heat dissipation holes 9.

[0055] At the same time, a lifting ring 13 is connected to the upper end of the traction rod 11, and a hook 14 is fixedly connected to the side wall of the power cabinet body 1, and the hook 14 is provided with two upper and lower ones. When the lifting ring 13 is hung on the hook 14 located at the upper end, the baffle 10 is in an inclined state, and the external heat dissipation hole 9 is opened. When the lifting ring 13 is hung on the hook 14 located at the lower end, the baffle 10 falls down to block the external heat dissipation hole 9.

[0056] Especially in snowy weather, after the outer heat dissipation holes 9 are blocked, the hot air can only go upward along the inner heat dissipation holes 201 on the partition 2, and the hot air will blow to the back of the solar panel 3, which can accelerate the melting of ice and snow on the solar panel 3, so that the solar panel 3 can generate electricity smoothly, and can also prevent equipment damage caused by excessive ice and snow.

[0057] The implementation process and principle of a combined distributed power supply for a smart park in the embodiment of the present application are as follows:

[0058] (i) When the angle of the solar panel 3 needs to be changed, the threaded rod 506 is driven to rotate by the motor, thereby driving the slider 505 and the toothed plate 504 to move, and the gear 503 and the adjusting shaft 501 are used to drive the adjusting block 502 to rotate. When the adjusting block 502 rotates, the angles of the movable support rods 4 on both sides will form a height difference, thereby driving the solar panel 3 to rotate and adjust its angle, thereby extending its working time and improving the power generation efficiency.

[0059] (ii) During the low electricity consumption period, the solar panel 3 is used to charge the battery 6. During the peak electricity consumption period, the battery 6 supplies power to the outside. Because the device can be installed near the user, the distance is short, the power transmission loss is small, and it can be reasonably allocated according to the electricity demand to meet different needs.

[0060] (III) In hot seasons, the cooling fan 8 cooperates with the inner and outer cooling holes 9 to dissipate heat for the entire device to keep the device running normally. In snowy weather, the outer cooling holes 9 can be closed so that the hot air can only flow upward along the inner cooling holes 201 on the partition 2 and blow toward the back of the solar panel 3, which can accelerate the melting of ice and snow on the solar panel 3, so that the solar panel 3 can smoothly generate electricity, and can also prevent equipment damage caused by excessive ice and snow.

[0061] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
