Description

Technical Field

[0001] The present invention relates to the field of power storage equipment, and in particular to a green building energy recovery power storage equipment. Background Art

[0002] Green building design is one of the important directions of modern building design. By rationally selecting and applying relevant technologies and strategies, buildings can protect the environment, save energy, and contribute to sustainable development while meeting people's living needs. At the same time, it helps to promote the sustainable development of the construction industry. Green building design can achieve the goal of sustainable development by optimizing the energy utilization of buildings, reducing pollution to the environment, and improving the comfort of employees. For example, installing solar panels on the roof of a building can fully utilize the roof space while storing energy for power generation, reducing dependence on traditional power grids, and promoting the rational use of energy and sustainable development.

[0003] The existing Chinese patent announcement number is: CN113489441B, which discloses a green building energy recovery and storage system, including a solar panel, the bottom end of the solar panel is equipped with a sunlight tracking system consisting of a bracket structure, a fixing frame, a base and a fixing foot, and several sets of solar panels and batteries constitute a storage system. The invention is provided with a solar energy storage system consisting of a bracket structure, a fixing frame, a base and a fixing foot. When in use, the controller receives and sends electric signals based on the weather information of the Internet of Things and the built-in sensor to control the equipment in the system, wherein the extension and retraction of the first electric push rod can drive the solar panel and the bracket structure to flip backward to adapt to the height of the sun, and when the second electric push rod is in use, one is extended and the other is retracted synchronously, driving the fixing frame to rotate on the upper surface of the base, thereby automatically tracking the sun from east to west, and then realizing the installation on the roof to utilize solar energy for storage, which effectively solves the problems of low sunlight utilization rate, high use cost, complex structure and inconvenient maintenance of existing rooftop solar panels.

[0004] The above-mentioned solar panels still have the following problems when in use:

[0005] ①. Since solar panel components will generate a certain voltage under the sunlight, it poses a certain safety hazard to operators;

[0006] ② Hot spot effect, that is, under reasonable lighting conditions, the shielded photovoltaic cells in a series branch will change from power generation units to power consumption units, not only not contributing to the output of the component, but also consuming the electricity generated by other cells, which will generate heat; this effect can seriously damage solar cells, because the shielded part will change from power generation to energy consumption, causing the local temperature of the component to rise sharply, which will not only cause safety hazards but also affect the lifespan; therefore, when the solar panel is repaired, an opaque object or material is required to cover the front surface of the component. The above-mentioned solar panels need to use additional materials for shielding during the repair time, which makes it inconvenient to carry and install opaque materials, affecting the overall repair and maintenance efficiency.

[0007] Therefore, it is necessary to invent a green building energy recovery and storage device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] The present invention provides Figure 1-Figure 7 A green building energy recovery and storage device is shown, including an arched mounting frame 1, the inner walls of the two side ends of the arched mounting frame 1 are fixedly connected with mounting plates 2, the interiors of the two mounting plates 2 are embedded with photovoltaic panel bodies 3, one side of the mounting plate 2 is fixedly connected with a storage box 4, the interior of the storage box 4 is hollow to form a cavity 5, a shielding cloth 8 is wound inside the cavity 5, one side of the storage box 4 is provided with a notch 6 connecting the cavity 5, one end of the shielding cloth 8 extends outward through the notch 6, the side end is fixedly connected with a weight block 10, both sides of the mounting plate 2 are fixedly connected with side limit plates 7, and the interior of the side limit plates 7 is provided with a moving channel 12, and the weight block 10 is slidably connected to the moving channel 12, so as to facilitate the movement of the weight block 10 to stretch the shielding cloth 8, so that there will be no wrinkles when the shielding cloth 8 is unfolded and rolled up.

[0036] The equipment also includes:

[0037] The driving assembly 9 includes a motor 901, and the outer wall of the storage box 4 is fixedly connected to the motor 901, and the output shaft of the motor 901 is transmission-connected to the driving shaft 902, the end of the driving shaft 902 is rotationally connected to the inner wall of the cavity 5 through a bearing, and the outer ring of the driving shaft 902 is wound and connected to the shielding cloth 8. The motor 901 is started, and the driving shaft 902 transmission-connected to the output shaft of the motor 901 is rotated, so that the shielding cloth 8 wound on the outer ring of the driving shaft 902 is rolled up or unrolled.

[0038] The fastening assembly 11 includes a rotating rod 1101, the inner wall of the cavity 5 is rotatably connected to the rotating rod 1101, and the outer ring of the rotating rod 1101 is fixedly sleeved with an arc plate 1102, and a mounting groove 1103 is opened inside the arc plate 1102, and the inside of the mounting groove 1103 is rotatably connected to an auxiliary roller 1104, and the auxiliary roller 1104 is in contact with the surface of the shielding cloth 8. The auxiliary roller 1104 rotatably connected inside the arc plate 1102 always presses against the outer surface of the shielding cloth 8 whose outer ring has been rolled up by the driving shaft 902, and does not affect the rolling of the shielding cloth 8 while performing the rolling and tightening operation.

[0039] The mounting plate 2 is tilted from the upper left to the lower right, and the storage box 4 is fixedly connected to the raised end outer wall of the mounting plate 2, so as to facilitate the unwinding of the shielding cloth 8. The weight block 10 is driven by gravity to smoothly unfold the unrolled shielding cloth 8 to cover the surface of the photovoltaic module.

[0040] The two side ends of the shielding cloth 8 move in the moving channels 12 arranged inside the two side limit plates 7, so as to ensure that the unfolding movement of the shielding cloth 8 is limited.

[0041] The shielding cloth 8 is black, and the inner surface of the shielding cloth 8 is coated with multiple layers of resin mixed with color paste to prevent light from passing through the shielding cloth 8 to illuminate the surface of the photovoltaic module, thereby achieving a shading effect, facilitating the staff to repair the photovoltaic module and ensuring the safety of the staff's subsequent repair and maintenance work.

[0042] The weight block 10 is in a horizontal "I" shape, and the two ends of the weight block 10 are respectively attached to and slidably connected with the inner walls of the moving channel 12 arranged inside the side limit plates 7 on both sides and the inner walls of the groove 13 connected to the moving channel 12, ensuring that the weight block 10 maintains stability when the shielding cloth 8 relies on its own gravity to drive the shielding cloth 8 to move during the unwinding process. At the same time, the moving channel 12 is connected with the notch 6, ensuring that the shielding cloth 8 can be unwound smoothly.

[0043] The weight block 10 can be attached to the side wall of the storage box 4 with the notch 6, so that the shielding cloth 8 can be rolled up. Figure 1 In the initial state shown, the weight block 10 is fixed in position.

[0044] A strip-shaped leakage opening 14 is provided inside the load-bearing block 10, and the leakage opening 14 is located above the shielding cloth 8, and the end surface where the shielding cloth 8 is fixedly connected to the load-bearing block 10 is flush with the bottom wall of the leakage opening 14, so that impurities scattered on the unfolded shielding cloth 8 can be directly discharged from the leakage opening 14.

[0045] There are two rotating rods 1101 , and the two rotating rods 1101 are symmetrically arranged up and down with reference to the transverse central axis of the driving shaft 902 as the symmetry axis, and two symmetrically arranged arc plates 1102 are fixedly inserted into the outer rings of the two rotating rods 1101 .

[0046] The outer ring movable sleeve of the rotating rod 1101 is equipped with a torsion spring, and one end of the torsion spring is fixedly connected to the inner wall of the cavity 5, and the other end of the torsion spring is fixedly connected to the arc plate 1102 fixedly inserted in the outer ring of the rotating rod 1101. The force exerted by the torsion spring causes the two arc plates 1102 to always be subjected to a force in the direction of the driving shaft 902.

[0047] An arc-shaped plate 1102 is internally rotatably connected with three groups of auxiliary rollers 1104 arranged at equal angles, and the arc size of the three groups of auxiliary rollers 1104 is equal to the arc size of the arc plate 1102. The auxiliary rollers 1104 rotatably connected inside the two arc-shaped plates 1102 always press against the outer surface of the shielding cloth 8 under the action of the torsion force of the torsion spring sleeved on the outer ring of the rotating rod 1101, and the shielding cloth 8 is wound and tightened without affecting its winding, thereby ensuring that the shielding cloth 8 is rolled up neatly and convenient for subsequent reuse.

[0048] Working principle:

[0049] When in use, the rotation of the drive shaft 902 unwinds the shielding cloth 8, and the mounting plate 2 is placed at an angle. Under the action of gravity, the load-bearing block 10 slides downward inside the moving channel 12, and the "I"-shaped load-bearing block 10 moves inside the preset moving channel 12 and the groove 13 inside the side limit plate 7, thereby ensuring the stability of the movement of the load-bearing block 10, and conveniently driving the unfolding of the entire shielding cloth 8, thereby covering the three photovoltaic panel bodies 3 embedded on the mounting plate 2. The load-bearing block 10 stretches the shielding cloth 8, so that the shielding cloth 8 will not be wrinkled when it is unfolded and rolled up, thereby extending the service life of the shielding cloth 8. At the same time, a coating is provided on the inner surface of the shielding cloth 8 to prevent light from passing through the shielding cloth 8 to illuminate the surface of the photovoltaic module, thereby achieving a shading effect, facilitating the maintenance of the photovoltaic module by the staff, avoiding the hot spot effect, and ensuring the safety of the subsequent maintenance work of the staff.

[0050] When the driving shaft 902 rotates to roll up the shielding cloth 8, the shielding cloth 8 drives the weight block 10 to move toward the storage box 4. As the shielding cloth 8 rolled up by the outer ring of the driving shaft 902 becomes thicker and thicker, the rolled up shielding cloth 8 presses against the two arc plates 1102, and the auxiliary roller 1104 rotatably connected inside the two arc plates 1102 always presses against the outer surface of the shielding cloth 8 under the action of the torsion force of the torsion spring sleeved on the outer ring of the rotating rod 1101, so that the shielding cloth 8 is rolled up without affecting its rolling while being rolled up and tightened, thereby ensuring that the shielding cloth 8 is rolled up neatly and convenient for subsequent reuse.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
