It should also be understood that in the context, when it is mentioned that an element or feature is connected to another element (one or more), it can not only be directly connected to the other (one or more) elements, but also indirectly connected to the other (one or more) elements through an intermediate element.
[0015] Before introducing the technical solution of the present invention, it is necessary to explain the creation background of the invention of the present invention. It is common that a large number of lighting devices are needed in mining areas at night or when the light intensity is poor to ensure the safe operation of the mining area and the safety of the surrounding workers. Traditional lighting devices rely on power grids for power supply, which have the problems of large energy consumption and environmental pollution. Photovoltaic power generation technology converts solar energy into electrical energy through photovoltaic equipment, providing environmentally friendly and renewable power for mining areas, solving the problems of traditional lighting devices. Photovoltaic equipment is often mounted on photovoltaic brackets. However, the continuous exploitation of mineral resources causes the soil or rock formations around the mining area to move, deform or be damaged. When the mining area of the area reaches a certain range, the movement and damage will affect the surface and the equipment around the surface. If the photovoltaic equipment is directly supported and fixed by the existing bracket in the mining area, as the mining operation in the mining area continues, the existing bracket is easy to fall over during use; and the mining area is relatively open. Under extreme climatic conditions such as strong winds or sandstorms, the existing bracket is also easy to fall over to damage the photovoltaic equipment, thereby increasing the use and maintenance cost of the photovoltaic equipment. See also Figures 1 to 6 The exemplary embodiment of the present invention provides a photovoltaic support for mining areas, including a base 1 and a pole 2 arranged at the top of the base 1, and also includes a first center of gravity correction mechanism for adjusting the center of gravity of the base 1, an inclination correction mechanism for adjusting the inclination of the pole 2, and a second center of gravity correction mechanism for adjusting the center of gravity of the pole 2. These three form a multi-element correction system of the photovoltaic support, which will be described in detail below: First center of gravity correction mechanism: First, see Figures 1 to 4The base 1 of the photovoltaic bracket is provided with a first hollow cavity, and the first center of gravity correction mechanism includes a first motor 41, and the first motor 41 is connected to a rotating shaft inserted into the first hollow cavity, and the part of the rotating shaft inserted into the first hollow cavity is provided with a first counterweight 124 that can rotate with the rotating shaft. Among them, a plurality of oblique support rods 11 are arranged in a circular array near the edge around the bottom end of the base 1. Specifically, the first motor 41 is arranged at the bottom of the base 1, and the rotating shaft is connected to the output end of the first motor 41 by power, and then penetrates into the first hollow cavity and is connected to the top of the first hollow cavity. After the collapse position is determined, the first motor 41 starts to drive the shaft to rotate, and the shaft rotates while driving the first counterweight 124 thereon to rotate synchronously, so that the first counterweight 124 is away from the position where the photovoltaic bracket may collapse or tilt, that is, the first counterweight 124 is moved to the symmetrical position where the photovoltaic bracket may collapse or tilt, and the weight at the position where the tilt or tilt may occur is increased and the weight at the corresponding position where the collapse may occur is reduced, so as to change the position of the center of gravity of the base 1 and the center of gravity of the entire photovoltaic bracket, thereby achieving preliminary correction of the center of gravity of the base 1. It should be noted that the first counterweight 124 is fan-shaped. In addition, as a preferred technical solution, the base 1 is also equipped with a horizontal sensor that can detect the tilt state of the upright 2.
[0016] Furthermore, based on the first counterweight 124, the base 1 is initially corrected to achieve the center of gravity. However, the base 1 is still not completely vertical to the ground and there is a risk of overturning. Therefore, the first center of gravity correction mechanism is further provided with a second counterweight 125 to assist in the correction. Figures 1 to 4 In some embodiments, a transverse partition 123 is provided in the first hollow cavity to obtain a first cavity 122 and a second cavity 121. The first cavity 122 accommodates a first counterweight 124; the second cavity 121 is provided with a second counterweight 125, and an electromagnetic locking device for controlling whether the second counterweight 125 rotates with the shaft. It should be understood that the present invention does not limit the vertical positions of the first cavity 122 and the second cavity 121. For example, the first cavity 122 accommodating the first counterweight 124 can be located above the second cavity 121, or below the second cavity 121. Figure 2The orientation shown in the figure is expanded to explain that the second cavity 121 is located above the first cavity 122 that accommodates the first counterweight 124, and the second counterweight 125 is arranged inside the cavity 121, and the electromagnetic locking device that controls whether the second counterweight 125 rotates with the shaft. When the center of gravity of the base 1 needs to be adjusted again, the electromagnetic locking device is turned on, and the second counterweight 125 can be connected to the shaft and rotate synchronously with the shaft to the required position. This electromagnetic locking device includes the following: a first electromagnetic member 128, which is arranged at the top of the second cavity 121; a metal ring 127, which is vertically slidably sleeved on the part of the shaft in the second cavity 121; a rotating sleeve 126, which is located below the metal ring 127 and fixedly connected to the second counterweight 125; for this purpose, the first electromagnetic member 128 controls the fixing and release of the metal ring 127, and when the metal ring 127 is released, it can be plugged with the rotating sleeve 126, so that the shaft can drive the rotating sleeve 126 and the second counterweight 125 to rotate, so as to optimize the center of gravity of the base 1 again. It should be noted that the above-mentioned plug-in method can be configured with a connecting pin to achieve plug-in, for example, a connecting pin 129 is configured at the bottom of the metal ring 127, and a plug-in hole is configured at the top of the rotating sleeve 126. Of course, the present invention does not make specific limitations on this, as long as the two can be plugged in.
[0017] It should be noted that the second counterweight 125 is fan-shaped. Further, the second counterweight 125 includes two groups of sub-counterweights, one of which is fixedly connected to the rotating sleeve 126, and the two groups of sub-counterweights are equipped with a second electromagnetic component to achieve adsorption or desorption. The purpose of adopting such a design is that when there is no need to re-optimize the position of the center of gravity of the base 1, the second counterweight 125 does not need to move. In order to ensure the relative balance of the base 1, we preferably design the second counterweight 125 as two groups of sub-counterweights arranged in a mirror image. When the center of gravity of the base 1 needs to be re-optimized, the second electromagnetic component is used to achieve the adsorption of the two groups of sub-counterweights as a whole before adjusting the center of gravity of the base 1.
[0018] In summary, the first center of gravity correction mechanism of the present invention can optimize the center of gravity position of the photovoltaic bracket according to specific terrain and environmental conditions through the all-round weight adjustment of the first counterweight 124, and the first center of gravity correction mechanism has the ability of dual adjustment processing to perform more refined center of gravity adjustment, so that the overall device can flexibly adjust the center of gravity of the equipment under different on-site environments, ensuring that it can remain stable under various environmental conditions.
[0019] Tilt correction mechanism: See also Figure 1 and Figure 5The tilt correction mechanism is used to automatically correct the state of the upright pole 2 when it is tilted by external weather factors. The tilt correction mechanism includes a mounting seat arranged at the top center of the base 1, the upright pole 2 is inserted into the mounting seat and hinged to the side of the mounting seat, and each hinge end is equipped with a strong torsion spring 5 to absorb and buffer vibration and impact energy. Specifically, the bottom end of the vertical pole 2 extends into the mounting seat, and the mounting seat is provided with two opposite side parts for hinged installation with the bottom end of the vertical pole 2, wherein the hinged ends of the two side parts are provided with strong torsion springs 5. When strong winds, storms or sandstorms occur in the mining area, due to the large force-bearing area of the solar photovoltaic panel 31 arranged on the vertical pole 2, when the wind force reaches a certain level, the wind force will blow the solar photovoltaic panel 31 and even drive the vertical pole 2 to fall in the corresponding direction. However, the vertical pole 2 will squeeze the strong torsion spring 5 at the hinged end while rotating, and the strong torsion spring 5 will be tightened. Then, after the strong wind in the mining area stops, the strong torsion spring 5 releases energy and drives the vertical pole 2 in the mounting seat to reset, thereby completing the correction of the tilt of the vertical pole 2. As a preferred technical solution, in some embodiments, the upper part of the vertical pole 2 is also provided with a wind direction sensor to determine the daily wind direction in the regional environment.
[0020] In summary, the inclination correction mechanism of the present invention adopts a structure in which a strong torsion spring 5 is set to further enhance the stability and safety of the photovoltaic bracket. When the vertical pole 2 swings unexpectedly due to strong wind or other external forces, the strong torsion spring 5 can respond quickly and apply force to quickly reset the vertical pole 2 to its original position.
[0021] Second center of gravity correction mechanism: See also Figure 1 and Figure 6 , this second center of gravity correction mechanism is used to correct the center of gravity of the upright pole 2 when the upright pole 2 faces different natural weather. The upright pole 2 is provided with a second hollow cavity, and the second center of gravity correction mechanism includes a second motor 42. This second motor 42 is preferably arranged at the top of the upright pole 2 to avoid interfering with the bottom structure of the upright pole 2. The second motor 42 is transmission-connected with a screw rod inserted into the second hollow cavity. The screw rod is provided with at least two groups of third counterweights with internal threads to form a rotating pair with the screw rod. Under the drive of the second motor 42, the third counterweights can move vertically along the screw rod. Specifically, the spiral pair formed by the above-mentioned screw rod and the third counterweights is equivalent to a ball screw structure, which can drive the third counterweights to realize vertical movement in the second hollow cavity by the rotation of the screw rod to adjust the center of gravity of the upright pole 2. For example, if encountering severe weather conditions such as strong winds or storms, moving the third counterweight to the upper part of the third hollow cavity can better resist wind pressure and wind load and reduce the risk of tipping over or damage; if the weather conditions in the mining area are relatively normal, moving the third counterweight to the lower part of the third hollow cavity, the center of gravity of the overall photovoltaic bracket device is lower, making it easier to fix the secondary photovoltaic bracket on the ground.
[0022] Preferably, the first motor 41 and the second motor 42 are both provided with motor covers for protection.
[0023] In summary, the second center of gravity correction mechanism of the present invention can intelligently adjust the center of gravity position of the neutral pole 2 of the photovoltaic support to cope with sudden severe weather.
[0024] See also Figure 1 As a preferred technical solution, the present invention also includes a photovoltaic panel 31 and a lighting fixture 32 connected to the photovoltaic panel 31. The upper part of the vertical pole 2 is provided with an extended fixing seat 21 for installing the photovoltaic panel and the lighting fixture 32, which is used to convert solar energy in the external environment into electrical energy and provide lighting treatment around the device. For example, Figure 1 As shown, the extension fixing seat 21 is specifically formed by a plurality of connecting rods and a support plate on the upper part of the vertical pole 2, and the photovoltaic panel 31 and the lighting fixture 32 are connected to the extension fixing seat 21 by fasteners to form a complete photovoltaic lighting device. It should be understood that the lighting fixture 32 is equipped with an intelligent controller 33 to monitor the charging state of the battery in the lighting fixture 32. To this end, the present invention can reduce the demand and dependence of the mining area on power resources, improve the independence of mining operations, and reduce the consumption of electricity in the mining area, saving energy while also improving the safety of nighttime operations in the mining area.
[0025] In summary, compared with existing mining area lighting devices, the photovoltaic bracket for mining areas provided by the present invention has obvious technical advantages.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. 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 replacements for some of the technical features therein.
