Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic support equipment, in particular to an installation support equipment for photovoltaic construction. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a new power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials. After receiving sunlight, photovoltaic panels directly convert solar radiation energy into electrical energy. There are two modes of operation: independent operation and grid-connected operation. During the construction and installation of photovoltaic projects, photovoltaic panels are generally installed on special supporting equipment.

[0003] Currently, the support equipment used for photovoltaic construction and installation on the market can be divided into fixed brackets, tilt-adjustable brackets and automatic tracking brackets according to the applied brackets. Among the fixed brackets, they can be divided into roof-type, ground-type and water-surface types according to the application sites. In water-surface photovoltaic construction, the brackets used in water-surface photovoltaic construction generally adopt floating and column-type. For water-surface photovoltaic construction, the column-type installation bracket needs to fix the bracket piles in the bottom mud. When facing shallow water, the column-type bracket has a greater advantage than the floating type. When facing a large area of ​​water or a large water depth, the floating type has a greater advantage than the column type.

[0004] When using floating brackets for surface photovoltaic construction, anchors are generally used to anchor the float, then the brackets are installed on the float, and then the photovoltaic panels are installed on the brackets. However, there are still some problems when using this type of photovoltaic construction support equipment. For example, the photovoltaic panels are installed on the brackets, and the brackets themselves have a certain height. When encountering extreme weather, such as strong winds and rainstorms, the photovoltaic panels will be impacted, making it possible for the photovoltaic panels to be damaged.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The photovoltaic construction installation support equipment starts the first electric telescopic rod in extreme weather, controls the return stroke of the first electric telescopic rod through the controller, and drives the installation frame and the photovoltaic panel to descend, so that the center of gravity of the photovoltaic panel moves downward, increasing its wind resistance. At the same time, water waves and rainwater accumulate in the water tank, increasing the counterweight of the float, thereby increasing the wind and wave resistance of the device. Rainwater enters the bottom of the inner cavity of the water tank through the one-way valve in the collection hole, so that the float floats upward due to the buoyancy of the water. After the float floats, it pulls the wire rope, which is tightened and straightened, and pulls the installation frame, making the installation frame and the photovoltaic panel above more stable.

[0021] 2. For the installation support equipment for photovoltaic construction, when the first electric telescopic rod controls the mounting frame to descend, the second electric telescopic rod follows and descends synchronously. The second electric telescopic rod is started during the descent, so that the output end of the second electric telescopic rod contacts the magnetic slider, and drives the magnetic slider downward, so that the magnetic slider contacts the pressure sensor, and transmits an electrical signal to the controller through the pressure sensor. The air pump is started through the controller to inflate the short airbag and the long airbag. After the short airbag and the long airbag are inflated, they are pushed upward from the storage slot, so that the short airbag and the long airbag form a surrounding protection for the mounting frame and the photovoltaic panel, thereby improving the wind and wave resistance of the mounting frame and the photovoltaic panel.

[0022] 3. The installation support equipment for photovoltaic construction, when the extreme weather is over, drives the installation frame to rise upward through the first electric telescopic rod. When the installation frame is raised, under the action of the fixed pulley, the installation frame pulls the wire rope, and then pulls the floating plate down. During the descent of the floating plate, the rainwater in the inner cavity of the water storage tank is pressurized, so that the rainwater in the inner cavity of the water storage tank is pumped to the inside of the delivery pipe through the pre-buried waterway, and the rainwater is transported to the inside of the installation frame through the delivery pipe. When the temperature of the photovoltaic panel is too high, the temperature of the surface of the photovoltaic panel is transferred to the heat sink, and the heat sink transfers the heat to the vertical copper plate. The vertical copper plate is cooled by the rainwater inside the installation frame, which indirectly cools the photovoltaic panel and reduces the risk of light spots on the photovoltaic panel due to sunlight.

DETAILED DESCRIPTION

[0033] 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.

[0034] Embodiment 1:

[0035] See also Figure 1-9 , a photovoltaic construction installation support device, comprising a floating body 1 and a controller, a first electric telescopic rod 11 is fixed on the top of the floating body 1, and the first electric telescopic rod 11 is controlled by the controller;

[0036] A mounting frame 2 is fixed to the output end of the first electric telescopic rod 11, and a photovoltaic panel 3 is arranged above the mounting frame 2;

[0037] Both sides of the floating body 1 are provided with stabilizing components, which are used to improve the stability of the photovoltaic panel 3;

[0038] The stabilizing assembly includes a water storage tank 4, which is partially located in the floating body 1, and a floating plate 41 is slidably and sealably connected in the water storage tank 4;

[0039] One or more collecting holes 42 are provided on the floating plate 41, and a one-way valve is provided in the collecting hole 42, and the one-way valve is used to input water flow into the water storage tank 4 in a one-way manner;

[0040] A fixed pulley 43 is provided in the floating body 1, and steel wire ropes 44 are fixed at the bottom of both ends of the mounting frame 2. After the end of the steel wire rope 44 away from the mounting frame 2 passes through the fixed pulley 43 and the water storage tank 4, it is fixed to the bottom of the floating plate 41 in the water storage tank 4. A sealing ring 45 is fixed at the place where the steel wire rope 44 passes through the water storage tank 4, and the sealing ring 45 is slidably connected with the steel wire rope 44. In the initial state, the mounting frame 2 and the floating plate 41 are in a stretched state;

[0041] The sealing ring 45 has an outer edge at one end close to the floating plate 41, and the bottom of the floating plate 41 abuts against the outer edge of the sealing ring 45. The sealing ring 45 supports and limits the top of the floating plate 41, so that a cavity is formed at the bottom of the inner cavity of the water storage tank 4.

[0042] Specifically, in the actual working process, the controller controls the first electric telescopic rod 11 to be in working state, and brings the photovoltaic panel 3 on the mounting frame 2 to a certain height. The photovoltaic panel 3 absorbs light energy and then converts it into electrical energy. In the working process, the height of the photovoltaic panel 3 can be adjusted according to actual needs, that is, the length of the first electric telescopic rod 11 can be adjusted;

[0043] In extreme weather conditions, such as strong winds and heavy rain, the controller can be used to control the return of the first electric telescopic rod 11, thereby lowering the center of gravity of the photovoltaic panel 3 and improving the stability of the photovoltaic panel 3 in such weather. At the same time, the water tank 4 can collect rainwater in such weather, and the rainwater enters the cavity formed by the water tank 4 and the bottom of the floating plate 41 through the collecting holes 42 on the floating plate 41. As the water flow in the water tank 4 increases, the floating plate 41 moves upward along the water tank 4. Because in the initial state, the mounting frame 2 and the floating plate 41 are in a stretched state, and when the first electric telescopic rod 11 returns, the steel wire rope 44 gradually changes from a stretched state to a contracted state, and as the floating plate 41 continues to move upward along the water tank 4, the steel wire rope 44 contracts and gradually changes from a stretched state. In this process, the buoyancy of the water flow in the water tank 4 on the floating plate 41 is converted into a pulling force of the steel wire rope 44 on the mounting frame 2, thereby further improving the stability of the photovoltaic panel 3 in such weather.

[0044] When the floating plate 41 moves upward along the water storage tank 4 to the top of the water storage tank 4, a blocking block can be set at the top of the inner wall of the water storage tank 4 to prevent the floating plate 41 from sliding out of the water storage tank 4. Specifically, the distance between the blocking block and the top of the water storage tank 4 can be 1-3 cm, thereby realizing the blocking block and the water flow in the water storage tank 4, limiting the floating plate 41 in a relatively fixed position, and ensuring its pulling force on the wire rope 44;

[0045] Furthermore, in extreme weather, waves hit the outside of the water tank 4 or splash into the inside of the water tank 4, or rainwater accumulates in the water tank 4. When rainwater or wave water enters the inside of the water tank 4, the weight of the water tank 4 increases, which in turn increases the weight of the float 1. After the float 1 is counterweighted by the water tank 4, the degree of bumping of the float 1 on the water surface is reduced. At the same time, due to the increase in the weight of the float 1, the risk of the float 1 being overturned by wind and waves is indirectly reduced, thereby improving the stability of the float 1 and the photovoltaic panel 3.

[0046] Embodiment 2:

[0047] A protective tube 26 is fixed to the bottom of the mounting frame 2, and the first electric telescopic rod 11 is located inside the protective tube 26. Second electric telescopic rods 27 are installed on both sides of the bottom of the mounting frame 2. The second electric telescopic rod 27 is controlled by a controller. An electromagnetic block 28 is fixed to the output end of the second electric telescopic rod 27, and the electromagnetic block 28 is controlled by the controller. An embedded groove 7 is opened on both sides of the protective tube 26 inside the floating body 1, and a pressure sensor 71 is fixed to the bottom of the embedded groove 7. The pressure sensor 71 is connected to the controller by electrical signals. An inner slide groove 72 is opened on both sides of the embedded groove 7. A magnetic slider 73 is slidably sleeved inside the inner slide groove 72. First springs 74 are fixed to the tops of both sides of the magnetic slider 73, and the top of one end of the first spring 74 is fixed to the top of the inner slide groove 72.

[0048] The floating body 1 is provided with storage grooves 5, which are located around the photovoltaic panel and are four in number. A short airbag 62 is provided in the storage grooves in the width direction of the photovoltaic panel, and a long airbag 63 is provided in the storage grooves in the length direction of the photovoltaic panel. An air pump 6 is provided inside the floating body 1, and a rain cover 61 is fixed to the outside of the air inlet pipe of the air pump 6. The air outlet pipe of the air pump 6 is connected with the short airbag 62 and the long airbag 63. In the initial state, the short airbag 62 and the long airbag 63 are stored in the storage groove and fit with the inner wall of the storage groove. The short airbag 62 and the long airbag 63 cooperate to achieve further protection of the photovoltaic panel.

[0049] Specifically, when the controller controls the mounting frame 2 to descend through the first electric telescopic rod 11, the mounting frame 2 drives the second electric telescopic rod 27 to descend synchronously. During the descent of the second electric telescopic rod 27, the second electric telescopic rod 27 is started, so that the second electric telescopic rod 27 drives the electromagnetic block 28 to descend synchronously. Then, the electromagnetic block 28 is energized by the controller, so that the electromagnetic block 28 contacts and adsorbs the magnetic slider 73 during the descent. At the same time, the electromagnetic block 28 drives the magnetic slider 73 to descend synchronously. The magnetic slider 73 contacts the pressure sensor 71 during the descent. After the pressure sensor 71 is squeezed, it transmits an electrical signal to the controller, and the controller controls the air pump 6 to start.

[0050] When the air pump 6 is started, the air pump 6 inflates the short airbag 62 and the long airbag 63 inside the storage tank 5. After the short airbag 62 and the long airbag 63 are inflated, they extend upward in the vertical direction to surround the mounting frame 2 and the photovoltaic panel 3. The surrounding layer formed by the short airbag 62 and the long airbag 63 around the photovoltaic panel 3 increases the wind and wave resistance of the photovoltaic panel 3, reduces the probability of it being overturned by wind and waves in this weather, and further improves its stability in extreme weather;

[0051] Furthermore, after the air pump 6 has completed inflating the short airbag 62 and the long airbag 63, the controller controls the second electric telescopic rod 27 to return, and cuts off the power supply to the electromagnetic block 28 when the second electric telescopic rod 27 returns, thereby driving the electromagnetic block 28 to disengage from the magnetic slider 73, and the magnetic slider 73 loses the pressure of the electromagnetic block 28 and resets under the action of the first spring 74, so that the magnetic slider 73 stops pressing down on the pressure sensor 71, so that the pressure sensor 71 stops sending an electrical signal to the controller, and then stops the controller from controlling the air pump 6 to inflate the long airbag 63 and the short airbag 62. After stopping the return stroke, the electromagnetic block 28 is energized again. , so that there is still an adsorption force between the magnetic slider 73 and the electromagnetic block 28. At the same time, since the magnetic slider 73 is slidably sleeved inside the inner slide groove 72 and will not be affected by the wind, the adsorption force between the magnetic slider 73 and the electromagnetic block 28 can enhance the stability of the electromagnetic block 28, and then indirectly increase the stability of the second electric telescopic rod 27 through the electromagnetic block 28, and then the second electric telescopic rod 27 enhances the stability of both sides of the mounting frame 2, thereby enhancing the stability of the photovoltaic panel 3 on the mounting frame 2. On the basis of the pulling force of the wire rope 44 on the mounting frame 2, the stability of the mounting frame 2 and the photovoltaic panel 3 in extreme weather is further increased.

[0052] It should be noted that the purpose of the second telescopic rod 27 in the present invention is to start and stop the air pump 6 to protect the photovoltaic panel 3. Therefore, in actual use, the electromagnetic block 28 can be selected according to actual needs. When the electromagnetic block 28 is not selected, the magnetic slider 73 can be replaced with an ordinary slider made of conventional material, and its material can be HDPE (modified high-density polyethylene) or other plastic materials. At the same time, the inflation time of the long air bag 63 and the short air bag 62 by the air pump 6 can be set according to the specific parameters of the selected air pump 6. Similarly, since the air pump 6 has the effects of inflation and exhaust, when the photovoltaic panel 3 is not needed to be protected, the air pump 6 can be controlled by the controller to exhaust the long air bag 63 and the short air bag 62 in the inflated state, so that the long air bag 63 and the short air bag 62 are exhausted and fall back into the storage slot 5 for the next use.

[0053] Embodiment three:

[0054] A water delivery pipe 9 is fixed on both sides of the first electric telescopic rod 11 at the bottom of the mounting frame 2, and the water delivery pipe 9 is located inside the protective pipe 26. The water delivery pipe 9 is connected to the mounting frame 2. A pre-buried water channel 91 is opened inside the floating body 1, and the end of the pre-buried water channel 91 away from the first electric telescopic rod 11 is connected to the water storage tank 4, and the end of the pre-buried water channel 91 close to the first electric telescopic rod 11 is connected to the water delivery pipe 9;

[0055] A support column 21 is fixed inside the mounting frame 2, a top frame 22 is fixed on the top of the support column 21, a photovoltaic panel 3 is fixed inside the top frame 22, a vertical copper plate 23 is clamped inside the top frame 22, a heat sink 24 is fixed on the top of the vertical copper plate 23, a limit screw 25 is sleeved on the inner thread of the mounting frame 2, and the vertical copper plate 23 is slidably sleeved on the outside of the limit screw 25;

[0056] Specifically, after the rainwater enters the cavity formed by the water storage tank 4 and the floating plate 41 through the one-way valve in the collecting hole 42, the rainwater flows into the interior of the embedded waterway 91 and the water delivery pipe 9. When the extreme weather is over, the controller controls the first electric telescopic rod 11 to be pushed out, so that the first electric telescopic rod 11 drives the mounting frame 2 and the photovoltaic panel 3 to move upward, and restores the height of the mounting frame 2 and the photovoltaic panel 3 to the initial state. When the top frame 22 rises, the top frame 22 pulls the steel wire rope 44, and the floating plate 41 is pulled downward along the water storage tank 4 through the steel wire rope 44. In the process of the floating plate 41 moving downward, due to the presence of the one-way valve in the collecting hole 42, the overflow of the water flow is avoided, and then the floating plate 41 applies pressure to the water flow in the cavity of the water storage tank 4 and the floating plate 41, as well as the water flow in the embedded waterway 91 and the water delivery pipe 9, so that the water flow in the cavity of the water storage tank 4 and the floating plate 41 passes through the embedded waterway 91 and the water delivery pipe 9, and is pumped into the interior of the mounting frame 2.

[0057] When the water flows into the interior of the mounting frame 2 through the water delivery pipe 9, the vertical copper plate 23 is cooled by the water flow. Since the vertical copper plate 23 is connected to the heat sink 24, and the photovoltaic panel 3 is located inside the top frame 22 and in contact with the heat sink 24, when the sun irradiates the photovoltaic panel 3 and heats up the photovoltaic panel 3, part of the heat of the photovoltaic panel 3 is absorbed by the heat sink 24 and transferred to the vertical copper plate 23 via the heat sink 24. The heat absorbed by the vertical copper plate 23 is finally absorbed by the rainwater in the mounting frame 2, thereby achieving the effect of heat dissipation and cooling of the photovoltaic panel 3 through the rainwater collected in the water storage tank 4;

[0058] At the same time, the water flow in the mounting frame 2 will gradually evaporate when the photovoltaic panel 3 is in normal working condition. When the water flow evaporates, it will absorb heat, and then absorb part of the heat around the photovoltaic panel 3, thereby further enhancing the heat dissipation and cooling effect of the photovoltaic panel 3, avoiding the direct sunlight from causing excessive temperature to the photovoltaic panel 3, reducing the probability of light spots on the surface of the photovoltaic panel 3, and thus increasing the service life of the photovoltaic panel 3.

[0059] It should be noted that after rainwater enters the cavity of the water storage tank 4 and the floating plate 41, it enters the interior of the water delivery pipe 9 through the embedded water channel 91, and a U-shaped channel is formed by the water storage tank 4, the embedded water channel 91 and the water delivery pipe 9. Under the action of the U-shaped tube principle, the liquid level in the water delivery pipe 9 rises with the rise of the floating plate 41, and the volume of the water storage tank 4 is much larger than the volume of the embedded water channel 91 and the water delivery pipe 9. Therefore, although part of the water flow in the water storage tank 4 will enter the embedded water channel 91 and the water delivery pipe 9, it will not affect the buoyancy of the water flow in the cavity of the water storage tank 4 and the floating plate 41 on the floating plate 41, thereby ensuring that the floating plate 41 can move in the water tank 4 in the vertical direction.

[0060] Embodiment 4:

[0061] A clamping groove 8 is provided inside one end of the floating body 1, a sealing plate 81 is fixed inside the clamping groove 8 by bolts, a sliding plate 82 is fixed outside the end of the floating body 1 opposite to the clamping groove 8, and one or more second springs 83 are provided outside the sliding plate 82. The notch of the clamping groove 8 and the shape of the second spring 83 are both in a horizontal T shape, and the length of the clamping groove 8 is much greater than the length of the sliding plate 82, and the sliding plate 82 can slide in the clamping groove 8;

[0062] Specifically, before the device is put into use on the water surface, the bolts on the top of the floating body 1 are first rotated to release the limit between the sealing plate 81 and the floating body 1, and then the sliding plate 82 on the outside of the adjacent group of floating bodies 1 is correspondingly inserted into the inside of the clamping groove 8 opened in the current floating body 1, and then the sealing plate 81 is clamped into the inside of the clamping groove 8 again, and then the sealing plate 81 and the floating body 1 are fixed by bolts, so that each group of floating bodies 1 is in a sliding sleeve relationship;

[0063] Furthermore, after the float 1 is put into use on the water surface, since the length of the snap-in groove 8 is much greater than the length of the sliding plate 82, when waves surge on the water surface, the two adjacent groups of floats 1 slide against each other. Through the mutual sliding between the two adjacent groups of floats 1, part of the potential energy of the impact of the waves on the floats is consumed, thereby improving the resistance of the multiple groups of floats 1 and photovoltaic panels 3 arranged in a square array to waves, thereby improving the stability of the floats 1 and photovoltaic panels 3 in the square array group, and through the buffering of the second spring 83, direct contact between the two adjacent groups of floats 1 is avoided, the vibration caused by the contact between the two adjacent groups of floats 1 is reduced, the influence on the components arranged above each group of floats 1 is reduced, the stability of the connection between each group of components is improved, and thus the stability of the photovoltaic panel 3 is improved.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
