Description

Technical Field

[0001] This invention relates to the field of power supply system technology, and in particular to a power supply system for construction supervision of power lines in mountainous areas. Background Technology

[0002] When constructing power lines in mountainous areas, some construction equipment and monitoring devices used for supervision require electricity. However, electricity is difficult to obtain in mountainous areas, so construction sites often need to use batteries or fuel generators to generate electricity. When using batteries, it is very inconvenient to go down the mountain to recharge them when the battery runs out of power. When using fuel generators, the pollution to the environment is greater and the cost of power supply is higher. Summary of the Invention

[0003] To address the shortcomings of existing power supply systems, such as inconvenient charging, significant pollution, and high costs, this invention proposes a power supply system for construction supervision of power lines in mountainous areas, which offers convenient charging, no pollution, and low cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A power supply system for construction supervision of power lines in mountainous areas includes a base, a bracket rotatably connected to the upper side of the base, a photovoltaic panel disposed on the upper side of the bracket, an energy storage battery electrically connected to the photovoltaic panel, one end of the photovoltaic panel tilting upward, and a rotating device for driving the bracket to rotate on the base.

[0006] The above setup enables convenient, pollution-free, and low-cost charging of the power supply system. Specifically, the base is bolted to the ground at the construction site. The photovoltaic panels generate electricity using solar energy and input the electricity into an energy storage battery. The energy storage battery, when connected to the construction equipment, powers the equipment for construction. The energy storage battery, when connected to a monitoring device, powers the monitoring device. The photovoltaic panels are tilted, maximizing the amount of radiation they receive, thereby increasing their power generation. In summary, this application utilizes solar energy for power generation, is pollution-free and low-cost, and allows for convenient daytime charging of the energy storage battery using the photovoltaic panels.

[0007] When the wind is strong and the wind direction is towards the back of the photovoltaic panel, the photovoltaic panel exerts an upward force on the support frame under the action of the wind, and the support frame exerts an upward force on the base. When the wind is strong, the bolts may loosen and the base may be lifted off the ground, which may cause damage to the power supply system.

[0008] The rotating device of this application can drive the bracket to rotate according to the wind force. When the wind force is strong, the rotating device rotates the bracket to adjust the angle of the photovoltaic panel so that the wind direction is towards the front of the photovoltaic panel. At this time, the photovoltaic panel exerts a downward force on the base under the action of the wind, thereby preventing the base from detaching from the ground.

[0009] Furthermore, the bracket includes a rotating plate, a support plate, and a connecting rod. The rotating plate is rotatably connected to the upper side of the base, the support plate is positioned above the rotating plate, and the rotating plate and the support plate are connected by the connecting rod. The photovoltaic panel is positioned above the support plate.

[0010] Furthermore, the upper side of the base is provided with an annular limiting groove, and the lower side of the rotating plate is fixedly connected to a limiting block, which is slidably connected in the limiting groove.

[0011] The above settings ensure good stability when the rotating plate rotates on the base.

[0012] Furthermore, the support plate is fixedly connected with a first ear plate and a second ear plate, which are located on opposite sides of the support plate. The lower end of the photovoltaic panel is connected to the first ear plate, and the upper end of the photovoltaic panel is connected to the second ear plate via a support rod.

[0013] The above settings result in good stability for the photovoltaic panels.

[0014] Furthermore, the connecting rod extends vertically, and its upper end is fixedly connected to the support plate. The rotating plate has a through hole, and the lower end of the connecting rod is inserted into the through hole and slidably connected to it. Several slots are provided on the upper side of the base, located outside the limiting groove and evenly spaced along its circumference. The through hole and slots correspond in position. A protrusion is fixedly connected to the connecting rod, and a spring is fitted onto the connecting rod. The upper end of the spring is connected to the protrusion, and the lower end of the spring is connected to the rotating plate. The rotating plate has an installation port. The rotating device includes a first rotating shaft rotatably connected to the base. The first rotating shaft passes through the installation port, and the upper part of the first rotating shaft... The first rotating shaft has several bowl-shaped air cups arranged in a circular array around its axis. The air cups are fixedly connected to the upper end of the first rotating shaft via a connecting arm. A damping sleeve is fitted onto the lower end of the first rotating shaft. The damping sleeve is rotatably connected to the base. Damping oil is provided between the damping sleeve and the first rotating shaft. A drive gear is fixedly connected to the outer side of the damping sleeve. A positioning shaft is fixedly connected to the base. A driven gear is rotatably connected to the positioning shaft. The driven gear meshes with the positioning shaft. A ring rack is fixedly connected to the inner side of the rotating plate. The ring rack meshes with the driven gear. The base is also equipped with a reset device for resetting the rotating plate.

[0015] With the above settings, this application exhibits good stability in strong winds. Specifically, when wind blows from one side of this application, the airflow passes through the wind cup and drives it to rotate. The wind cup then drives the first rotating shaft to rotate. When the wind force is relatively low, the rotation speed of the first rotating shaft is slow. At this time, the first rotating shaft and the damping sleeve rotate relative to each other. The damping oil can be silicone oil, which has good viscosity. The greater the relative rotation speed between the first rotating shaft and the damping sleeve, the greater the damping between them. Conversely, the smaller the relative rotation speed, the smaller the damping. Since the first rotating shaft rotates at a low speed, the reset device prevents the rotating plate from rotating. In other words, the wind will not affect the photovoltaic panel, and the photovoltaic panel generates electricity normally.

[0016] When the wind is strong and blowing towards the back of the photovoltaic panel, the first rotating shaft rotates rapidly. The damping between the first rotating shaft and the damping sleeve is significant, and the reset device cannot prevent the rotating plate from rotating. The damping sleeve rotates under the damping force, driving the rotating plate through the drive gear, driven gear, and ring rack. The rotating plate then drives the photovoltaic panel to rotate. When the front of the photovoltaic panel faces the wind, the panel moves downwards under the wind force. The connecting rod moves downwards along the through hole and inserts into the corresponding slot. At this point, the rotating plate cannot continue to rotate (the first rotating shaft spins freely). The photovoltaic panel exerts a downward force on the base, pressing the base firmly against the ground, thus preventing the base from separating from the ground. When the wind force decreases, the photovoltaic panel moves upwards under the action of the spring. The connecting rod disengages from the slot, and the rotating plate rotates under the action of the reset device, causing the photovoltaic panel to return to its initial position.

[0017] When the wind is strong and facing the front of the photovoltaic panel, the photovoltaic panel moves downward under the action of the wind, the connecting rod is inserted into the slot, and the base is pressed firmly on the ground.

[0018] Furthermore, the connecting rod sleeve is provided with a limit sleeve, the lower end of which is fixedly connected to the rotating plate, and the upper end of the limit sleeve is provided with an inward flange, the lower side of which abuts against the protrusion.

[0019] With the above settings, when a strong wind blows towards the back of the photovoltaic panel, the photovoltaic panel will not move upward.

[0020] Furthermore, the reset device includes a sliding plate fixedly connected to the base and extending vertically. A second rotating shaft passes through the lower end of the sliding plate. A driven bevel gear is fixedly connected to the second rotating shaft. An annular drive bevel gear is arranged along the edge of the rotating plate. The annular drive bevel gear and the driven bevel gear mesh. A winding wheel is fixedly connected to the second rotating shaft. A reversing wheel is rotatably connected to the upper end of the sliding plate. A weight is slidably connected to the sliding plate. A stop block abuts against the lower side of the weight. The stop block and the sliding plate are fixedly connected. A pull wire is wound on the winding wheel. The pull wire passes through the reversing wheel and is connected to the weight.

[0021] With the above setup, when the wind force is low, the resistance between the first rotating shaft and the damping sleeve is small and cannot overcome the weight of the block, meaning the block prevents the rotating plate from rotating. When the wind force is high, the resistance between the first rotating shaft and the damping sleeve is large and can overcome the block, driving the rotating plate to rotate. At this time, the ring drive bevel gear drives the winding wheel to rotate through the driven bevel gear and the second rotating shaft. The winding wheel winds the pull wire and drives the block to move upward. The block leaves the stop and moves upward along the sliding plate. Since the weight of the block remains constant, the resistance when the rotating plate rotates will not increase with the increase of the rotation angle. That is, under constant wind force, the rotating plate will continue to rotate under the action of the first rotating shaft until the front of the photovoltaic panel faces the wind (after facing the wind, the lower end of the connecting rod inserts into the slot, causing the rotating plate to stop rotating). When the wind force decreases, under the action of the block's gravity, the block moves downward and re-abuts the stop, while the block drives the pull wire. The winding wheel releases the pull wire and rotates, causing the rotating plate to rotate back to its initial position.

[0022] Furthermore, the winding wheel has a first annular groove in its circumference, and the reversing wheel has a second annular groove in its circumference. One end of the pull wire is wound in the first annular groove, and the pull wire passes through the second annular groove.

[0023] The above settings increase the stability of the pull cable. Attached Figure Description

[0031] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0032] See Figures 1 to 7A power supply system for construction supervision of power lines in mountainous areas includes a base 11, a bracket 12 rotatably connected to the upper side of the base 11, a photovoltaic panel 13 disposed on the upper side of the bracket 12, an energy storage battery (not shown in the figure) electrically connected to the photovoltaic panel 13, one end of the photovoltaic panel 13 tilting upward, and a rotating device 14 for driving the bracket 12 to rotate on the base 11.

[0033] The above setup enables convenient, pollution-free, and low-cost charging of the power supply system. Specifically, the base 11 is fixed to the ground at the construction site with bolts. The photovoltaic panel 13 generates electricity using solar energy and inputs the electrical energy into the energy storage battery. The energy storage battery, when connected to the construction device, can drive the construction device to perform construction. The energy storage battery, when connected to the monitoring device, can drive the monitoring device to operate. The photovoltaic panel 13 is tilted, thus maximizing the amount of radiation received by the photovoltaic panel 13, thereby increasing the power generation of the photovoltaic panel 13. In summary, this application utilizes solar energy for power generation, which is pollution-free and low-cost, and allows for convenient charging of the energy storage battery using the photovoltaic panel 13 during the day.

[0034] Strong winds are common in mountainous areas. When the wind is strong and the wind direction is towards the back of the photovoltaic panel 13, the photovoltaic panel 13 exerts an upward force on the support 12 under the action of the wind, and the support 12 exerts an upward force on the base 11. When the wind is strong, the bolts may be loosened and the base 11 may be lifted off the ground, thereby causing damage to the power supply system.

[0035] See Figure 6 The rotating device 14 of this application can drive the bracket 12 to rotate according to the wind force. When the wind force is strong, the rotating device 14 rotates the bracket 12 to adjust the angle of the photovoltaic panel 13 so that the wind direction is towards the front of the photovoltaic panel 13. At this time, the photovoltaic panel 13 exerts a downward force on the base 11 under the action of the wind, thereby preventing the base 11 from detaching from the ground.

[0036] In one implementation, the bracket 12 includes a rotating plate 121, a support plate 122, and a connecting rod 123. The rotating plate 121 is rotatably connected to the upper side of the base 11, the support plate 122 is disposed above the rotating plate 121, and the rotating plate 121 and the support plate 122 are connected by the connecting rod 123. The photovoltaic panel 13 is disposed on the upper side of the support plate 122.

[0037] As one implementation, the upper side of the base 11 is provided with an annular limiting groove 111, and the lower side of the rotating plate 121 is fixedly connected to a limiting block 1211, which is slidably connected in the limiting groove 111.

[0038] The above settings ensure good stability when the rotating plate 121 rotates on the base 11, and the rotating plate 121 will not detach from the base 11.

[0039] In one implementation, the support plate 122 is fixedly connected with a first ear plate 1221 and a second ear plate 1222. The first ear plate 1221 and the second ear plate 1222 are arranged on opposite sides of the support plate 122. The lower end of the photovoltaic panel 13 is connected to the first ear plate 1221, and the upper end of the photovoltaic panel 13 is connected to the second ear plate 1222 through the support rod 131.

[0040] The above settings result in good stability for photovoltaic panel 13.

[0041] In one implementation, the connecting rod 123 extends vertically, and its upper end is fixedly connected to the support plate 122. The rotating plate 121 is provided with a through hole 1212. The lower end of the connecting rod 123 is inserted into the through hole 1212 and slidably connected to it. The upper side of the base 11 is provided with several slots 112, which are located outside the limiting groove 111 and are evenly spaced along the circumference of the limiting groove 111. The through hole 1212 and the slot 112 are positioned correspondingly. The connecting rod 123 is fixedly connected to a protrusion 1231. A spring 1232 is sleeved on the connecting rod 123. The upper end of the spring 1232 is connected to the protrusion 1231, and the lower end of the spring 1232 is connected to the rotating plate 121. The rotating plate 121 is provided with an installation port 1213. The rotating device 14 includes a first rotating shaft 141 rotatably connected to the base 11. The first rotating shaft 141 passes through the installation port 121. 3. The upper end of the first rotating shaft 141 is provided with several bowl-shaped air cups 142. The air cups 142 are arranged in a circular array with the axis of the first rotating shaft 141 as the center. The air cups 142 are fixedly connected to the upper end of the first rotating shaft 141 through the connecting arm 143. The lower end of the first rotating shaft 141 is fitted with a damping sleeve 144. The damping sleeve 144 is rotatably connected to the base 11. Damping oil 145 is provided between the damping sleeve 144 and the first rotating shaft 141. The outer side of the damping sleeve 144 is fixedly connected with a drive gear 1441. The base 11 is fixedly connected with a positioning shaft 113. The positioning shaft 113 is rotatably connected with a driven gear 146. The driven gear 146 meshes with the positioning shaft 113. The inner side of the rotating plate 121 is fixedly connected with a ring rack 1214. The ring rack 1214 meshes with the driven gear 146. The base 11 is also provided with a reset device 15 for resetting the rotating plate 121.

[0042] With the above settings, this application exhibits good stability even in strong winds. For details, please refer to... Figure 5When a relatively weak wind blows from one side of this application, the airflow passes through the wind cup 142 and drives the wind cup 142 to rotate. The wind cup 142 drives the first rotating shaft 141 to rotate. When the wind force is relatively small, the rotation speed of the first rotating shaft 141 is relatively slow. At this time, the first rotating shaft 141 and the damping sleeve 144 rotate relative to each other. The damping oil 145 can be set as silicone oil. Silicone oil has good viscosity. The greater the relative rotation speed between the first rotating shaft 141 and the damping sleeve 144, the greater the damping between the first rotating shaft 141 and the damping sleeve 144. Conversely, the smaller the relative rotation speed between the first rotating shaft 141 and the damping sleeve 144, the smaller the damping between the first rotating shaft 141 and the damping sleeve 144. Since the speed of the first rotating shaft is relatively small at this time, the reset device 15 prevents the rotating plate 121 from rotating. That is, at this time, the wind will not affect the photovoltaic panel 13, and the photovoltaic panel 13 generates electricity normally.

[0043] See Figure 6 and Figure 7 When the wind is strong and blowing towards the back of the photovoltaic panel 13, the first rotating shaft 141 rotates very quickly. The damping between the first rotating shaft 141 and the damping sleeve 144 is large, and the reset device 15 cannot prevent the rotating plate 121 from rotating. The damping sleeve 144 rotates under the action of damping. The damping sleeve 144 drives the rotating plate 121 to rotate via the drive gear 1441, the driven gear 146, and the ring rack 1214. The rotating plate 121 drives the photovoltaic panel 13 to rotate. When the front of the photovoltaic panel 13 faces the wind, that is, when the wind direction is towards the front of the photovoltaic panel 13, the photovoltaic panel 13... Under the influence of wind, the photovoltaic panel 121 moves downwards, and the connecting rod 123 moves downwards along the through hole 1212 and inserts into the corresponding slot 112. (If the connecting rod is not aligned with the slot 112 at this time, the connecting rod will abut against the base, the rotating plate will continue to rotate, and the lower end of the connecting rod will slide relative to the base. When the connecting rod moves to the adjacent slot 112, the connecting rod will insert into the slot 112.) At this time, the rotating plate 121 cannot continue to rotate (the first rotating shaft 141 rotates freely), and the photovoltaic panel 13 applies a downward force to the base 11, pressing the base 11 firmly onto the ground, thereby preventing the base 11 from leaving the ground. When the wind force decreases, the photovoltaic panel 13 moves upwards under the action of the spring 1232, the connecting rod 123 and the slot 112 disengage, and under the action of the reset device 15, the rotating plate 121 rotates, thereby causing the photovoltaic panel 13 to rotate back to its initial position.

[0044] See Figure 7 When the wind is strong and facing the front of the photovoltaic panel 13, the photovoltaic panel 13 moves downward under the action of the wind, the connecting rod 123 is inserted into the slot 112, and the base 11 is pressed firmly on the ground.

[0045] As one implementation, the connecting rod 123 is provided with a limiting sleeve 1233. The lower end of the limiting sleeve 1233 is fixedly connected to the rotating plate 121. The upper end of the limiting sleeve 1233 is provided with a flange 1234 facing inward. The lower side of the flange 1234 abuts against the protrusion 1231.

[0046] With the above settings, when a strong wind blows towards the back of the photovoltaic panel 13, the photovoltaic panel 13 will not move upward, thereby preventing the connecting rod 123 from being pulled out of the through hole 1212.

[0047] In one implementation, the reset device 15 includes a sliding plate 151 that is fixedly connected to the base 11 and extends vertically. The lower end of the sliding plate 151 passes through a second rotating shaft 152. The second rotating shaft 152 is fixedly connected to a driven bevel gear 153. An annular drive bevel gear 154 is provided along the edge of the rotating plate 121. The annular drive bevel gear 154 and the driven bevel gear 153 mesh. The second rotating shaft 152 is fixedly connected to a winding wheel 155. The upper end of the sliding plate 151 is rotatably connected to a reversing wheel 156. The sliding plate 151 is slidably connected to a weight 157. The lower side of the weight 157 abuts against a stop block 1511. The stop block 1511 and the sliding plate 151 are fixedly connected. The winding wheel 155 is wound with a pull wire 158. The pull wire 158 is connected to the weight 157 via the reversing wheel 156.

[0048] With the above configuration, when the wind force is low, the resistance between the first rotating shaft 141 and the damping sleeve 144 is small and cannot overcome the gravity of the weight 157. That is, the weight 157 prevents the rotation of the rotating plate 121. See [link to relevant documentation]. Figure 6 When the wind force is strong, the resistance between the first rotating shaft 141 and the damping sleeve 144 is large and can overcome the weight 157 to drive the rotating plate 121 to rotate. At this time, the ring drive bevel gear 154 drives the winding wheel 155 to rotate through the driven bevel gear 153 and the second rotating shaft 152. The winding wheel 155 winds the pull wire 158 and drives the weight 157 to move upward. The weight 157 leaves the stop block 1511 and moves upward along the sliding plate 151. Since the weight of the weight 157 remains unchanged, the resistance of the rotating plate 121 when rotating will not increase with the increase of the angle of rotation. That is, under the condition of constant wind force, the rotating plate 121 will continue to rotate under the action of the first rotating shaft 141 until the front of the photovoltaic panel 13 faces the wind (after facing the wind, the lower end of the connecting rod 123 inserts into the slot 112 to stop the rotating plate 121 from rotating). When the wind force decreases, under the gravity of the weight 157, the weight 157 moves downward and comes into contact with the stop block 1511 again. The weight 157 drives the pull wire 158, and the winding wheel 155 releases the pull wire 158 and rotates. The winding wheel 155 causes the rotating plate 121 to rotate back to its initial position.

[0049] As one implementation, the winding wheel 155 is provided with a first annular groove 1551 in the circumference, the reversing wheel 156 is provided with a second annular groove 1561 in the circumference, one end of the pull wire 158 is wound in the first annular groove 1551, and the pull wire 158 passes through the second annular groove 1561.

[0050] The above settings increase the stability of the pull wire 158.
