Description

Technical Field

[0001] The invention belongs to the technical field of reducing wind loads in near-ground photovoltaic power stations, and in particular relates to a technical design of a movable windbreak wall. Background Art

[0002] At present, photovoltaic brackets are often damaged by strong winds in photovoltaic power stations. In this case, it is very costly to redesign the bracket system. For this reason, windbreak walls are often set up to block the incoming atmosphere to reduce the wind load on the photovoltaic panel surface.

[0003] Since the wind load acting on the photovoltaic array is uneven and the wind direction is random, the use of a four-sided enclosed windbreak wall can achieve a wind reduction effect in all wind directions of the photovoltaic array, but this type of windbreak wall cannot be flexibly arranged and the economic cost is too high. The four-sided enclosed windbreak wall is used to reduce the wind pressure of each row and make up for the defects of the two-sided and three-sided enclosed windbreak walls. It increases the cost of the windbreak wall and is not the best choice for areas where the wind direction is fixed all year round and occasionally unstable.

[0004] Patent CN202010735761.7 introduces a herringbone photovoltaic array windbreak wall, which is mainly used in the northwest region. By laying out the photovoltaic array in a herringbone shape, it combines the advantages of photovoltaic power stations and windbreak walls, effectively reducing evaporation in the northwest Gobi and reducing wind speed. Although the device can reduce evaporation and improve soil in the northwest region, it can only resist a fixed wind direction and is not very suitable for areas with multiple wind directions.

[0005] Patent CN202310021582.0 discloses a solar power generation device with windproof function, which has a movable protective plate. When the wind speed is strong, the protective plate can be moved close to the photovoltaic panel through a pushing mechanism. However, since there is only one protective plate and the direction cannot be adjusted, the wind direction that can be resisted is also fixed, which is not suitable for windy areas. Summary of the invention

[0006] The patent of the present invention provides a movable diamond-shaped photovoltaic windbreak wall, which can more intelligently and effectively protect photovoltaic panels and reduce the damage caused by wind loads by adding a track design and a weather vane, so as to solve the technical problem in the prior art that the wind pressure on photovoltaic panels cannot be reduced while effectively saving resources due to the changeable wind direction in some areas.

[0007] The purpose of the present invention is achieved as follows: A movable rhombus-shaped photovoltaic windshield wall comprises: a movable smooth track, a weather vane 2, a wind pressure sensor 3, a motor 4, an airplane wheel 5 and a windshield 6; the movable smooth track comprises four tracks connected in sequence to form a rhombus-shaped track, and a wind vane 2 for detecting wind direction and a wind pressure sensor 3 for detecting wind pressure are arranged at the four corners of the rhombus-shaped track; a plurality of windshields 6 are installed on each track, and a motor 4 and a plurality of airplane wheels 5 are installed at the bottom of each windshield, and the motor 4 is used to drive the airplane wheel 5 according to the wind pressure detected by the wind pressure sensor and the wind direction detected by the wind vane, so that the windshield 6 slides on the track to form a windshield wall for windshield.

[0008] Preferably, it also includes an electromagnetic lock 1, which is installed on the side of the windshield and is used to achieve the connection between the two windshields; Preferably, it also includes a slot, and the windshield plates are connected in a slot-type manner; Preferably, the windshields are connected to form a herringbone windshield wall or a diamond-shaped surrounding windshield wall; Preferably, it further comprises a console, the console comprises a plurality of switch buttons, and the number of windshields can be controlled by the switch buttons, wherein the number of the switch buttons is the same as the number of the windshields; Preferably, the driving circuit of the windshield comprises a plurality of parallel main branches, and the plurality of parallel main branches are connected to a power supply;' Preferably, the power supply is provided by solar energy; Preferably, the power supply is a battery; Preferably, the main branch includes multiple parallel branches, each parallel branch includes: an electromagnetic lock, a switch and a motor, the electromagnetic lock is connected in series with the switch, and the branch in which the electromagnetic lock and the switch are connected in series is further connected in parallel with the motor.

[0009] By adopting the above technical solution, the beneficial effects of the present invention are: Compared with the prior art, the present invention can move the windshield and quickly combine it into a large windshield in the required area, which solves the problem of the number of windshields, effectively and reasonably utilizes resources, and greatly reduces wind pressure, which has great advantages. At the same time, the electric energy used in the present invention can be taken from the electric energy converted from solar photovoltaic panels, which further realizes the utilization of resources and improves the utilization rate of resources. The present invention uses a circuit to control the movement of the windshield, and the windshield can be remotely controlled, which is more intelligent and convenient than the prior art.

[0010] Compared to the herringbone photovoltaic windbreak wall, the patent of the present invention can withstand wind loads from multiple wind directions, and has multiple windbreak walls to block the wind, not limited to blocking one wind direction. In addition, the patent of the present invention uses windshields to reduce wind pressure and protect photovoltaic panels. It does not use photovoltaic panels as windbreak walls like the herringbone photovoltaic windbreak wall. If there is no protection for a long time, the wind load will seriously damage the photovoltaic panels. The windshield designed by the patent of the present invention as a windbreak wall will not cause serious damage to the photovoltaic panels. Compared to the four-sided enclosed windbreak wall, this device uses the goose formation effect. By contrasting the herringbone arrangement with the horizontal arrangement, the wind is diverted to the two sides of the herringbone, which better reduces the wind pressure. The movable design will also effectively utilize the windshields that are not used by the four-sided enclosed windbreak wall, reducing the cost of the windshields.

[0011] The patent of this invention is an effective windbreak wall designed to adapt to areas with multiple wind directions. Through multiple windbreaks and multiple windbreaks that are movable, each region can increase or decrease windbreaks according to local conditions, change the combination of windbreaks, and more effectively and efficiently reduce wind pressure in different wind directions in areas with multiple wind directions by changing the number and combination of windbreaks, thereby improving the applicability of multiple regions with multiple wind directions and different wind forces.

[0013] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0014] like Figure 1-Figure 7As shown, a movable diamond-shaped photovoltaic windshield wall is used to reduce the wind load acting on the photovoltaic panel 7, including: a movable smooth track, an electromagnetic lock 1, a wind vane 2, a wind pressure sensor 3, a motor 4, an aircraft wheel 5 and a windshield 6. Four diamond-shaped ditches for placing the movable smooth track are excavated 0.6m below the ground in the area where the windshield wall needs to be installed. After the movable smooth track is placed, the windshield 6 is arranged. The windshield 6 is fixedly supported by steel and the electromagnetic lock 1 and the matching aircraft wheel 5 are installed. The windshield is placed on the smooth track, and multiple windshields 6 can be placed, such as 4 windshields 6 can be placed on each track. The multiple windshields 6 and related components on each track constitute a trunk circuit. The four tracks correspond to four trunk circuits. The four trunk circuits are connected in parallel and powered by a power supply. The power of the power supply can be taken from the power converted from the solar photovoltaic panel, which further realizes the utilization of resources and improves the utilization rate of resources. Each trunk circuit includes a wind pressure sensor, multiple windshields 6 and a corresponding number of electromagnetic locks 1 and motors 4. The movable diamond-shaped photovoltaic windshield wall uses motors and wind pressure sensors to remotely control the windshields through four trunk circuits. When the wind pressure reaches a certain value, such as 0.5kpa in the northwest region, the specific value depends on the local average wind speed. The pressure sensor will act as a switch to turn on the switch, so that the left and right windshields are slowly moved together by the motor to form a herringbone shape, and then the adjacent windshields are interlocked through electromagnetic locks to form a large windshield wall to resist the wind. Figure 6-7 The operator can control the electromagnetic lock through the console. Each electromagnetic lock has a corresponding switch button to control the corresponding electromagnetic lock and thus control the number of windshield connections. For example, if the switch button 2 on the console is pressed, the electromagnetic lock on the second fast light shield will not work, resulting in the disconnection between the second windshield and the third windshield. Therefore, different numbers of windshields and / or different numbers of trunk circuits can be set according to local conditions to realize a movable diamond-shaped photovoltaic windshield wall.

[0015] Due to the uncertainty of wind, in order to respond to and defend against the damage of wind load more quickly, a diamond track line is set up. Multiple windshields 6 can be placed on each side of the diamond. A wind pressure sensor 3 is installed at each corner to detect wind pressure, and a motor 4 is set to drive the windshield 6 to move. Each wind pressure sensor 3 and the windshields 6 on both sides of the corner, the motor 4, the electromagnetic lock 1 and the power supply form a complete circuit, so that it can achieve the effect of resisting a certain wind direction and reducing wind pressure. Moreover, when two large windshield walls are formed on both sides of the interlocking angles of adjacent windshields, a herringbone shape will be formed, and the direction of the corner is the wind direction to be resisted. Due to the goose formation effect and the reference to the herringbone photovoltaic windshield wall, this design will greatly reduce wind pressure.

[0016] Figure 8The control flow chart of the movable diamond-shaped photovoltaic windbreak wall is shown, comprising the following steps: Step 1: The wind vane detects and transmits wind direction information; Step 2: The wind sensor detects whether the preset value has been reached, if so, proceed to step 3; Step 3: Circuit start-up; Step 4: Press the button to determine the amount of movement of the windshield, the motor moves the windshield, and the electromagnetic lock connects the two boards; Step 5: Form a windbreak wall to block the wind.

[0017] In another embodiment, the connection between the windshields can be a slot-type connection or any other connection method that can connect two windshields; the movement of the windshield can be manually pushed, or other electric drive, and can be any method of moving the windshield; the circuit loop connection can add other driving devices or reduce the replacement device to form a loop to drive the windshield; the diamond ditch can be other herringbone-shaped ditches, and the track form can be different styles.

[0018] Compared with the existing technology, this device realizes the use of mobile windshields. The windshields of traditional technology use fixed installation, and steel is used to support and fix the entire windshield laterally. However, the number of windshields will be a problem in fixed installation. Too many windshields will lead to waste of resources, and too few windshields will not be able to effectively resist wind loads. In contrast, this device can move the windshields and quickly combine them into a large windshield in the required area, overcoming the problem of the number of windshields. It not only effectively and reasonably utilizes resources, but also greatly reduces wind pressure, exerting a huge advantage. At the same time, the electric energy used in the device can be taken from the electric energy converted from solar photovoltaic panels, further realizing the utilization of resources and improving the utilization rate of resources. This device uses circuits to move the windshield wall, and the windshield can be remotely controlled. Compared with the existing technology, it is more intelligent and convenient.

[0019] Compared with the herringbone photovoltaic windbreak wall, this device can withstand wind loads from multiple wind directions, and has multiple windbreak walls to block the wind, not just one wind direction. In addition, this device uses windshields to reduce wind pressure and protect photovoltaic panels, instead of using photovoltaic panels as windbreak walls like the herringbone photovoltaic windbreak wall. If there is no protection for a long time, wind loads will seriously damage photovoltaic panels. The windshield designed in this device as a windbreak wall will not cause serious damage to photovoltaic panels. Compared with the four-sided enclosed windbreak wall, this device uses the goose formation effect. By contrasting the herringbone arrangement with the horizontal arrangement, the wind is diverted to the two sides of the herringbone, which better reduces the wind pressure. The movable design will also effectively utilize the windshields that are not used by the four-sided enclosed windbreak wall, reducing the cost of the windshields.

[0020] This device is an effective windbreak designed to adapt to areas with multiple wind directions. Through the mobile design, local areas can increase or decrease windbreaks according to local conditions and change the combination of windbreaks. This device is expected to be more effective and efficient in reducing wind pressure in areas with multiple wind directions and achieve more rational use of resources.

[0021] The above shows and describes the basic principle and main features of the present invention and the advantages of the present invention. At the same time, the present invention is not limited by the above embodiments, and thus the present invention may have various changes and improvements without departing from the principle and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed for protection.
