Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, in particular to a large-current and low-voltage photovoltaic component. Background Art

[0002] Photovoltaic modules are products that convert solar energy into electrical energy. The production process is to package photovoltaic cells to form photovoltaic panels, and then combine photovoltaic panels with mounting components to form photovoltaic modules. The photovoltaic cells on the photovoltaic panels are arranged in a matrix, and the photovoltaic cells arranged in the matrix are connected in series, so that the current generated by the photovoltaic cells arranged in the matrix flows in a serpentine manner in the same direction. However, the current generated by the photovoltaic cells arranged in the matrix flows in a serpentine manner in the same direction, which will increase the current loss.

[0003] Nowadays, photovoltaic modules are mostly installed in rural areas in northern my country. Due to the dry climate and low rainfall in northern my country, photovoltaic modules are more advantageous in northern China. Flat roofs with edges are the main building materials in northern China, because flat roofs can better adapt to areas with less rainfall. Sloped roofs are more suitable for areas with heavy rainfall to effectively drain water and prevent floods. The edges of flat roofs can not only block and guide water to flow out of the roof drains, but also enhance the structural support and protection of the roof. The construction cost of flat roofs is lower than that of sloping roofs, and the construction is simple. There is no need for complex roof structures and waterproofing, which reduces construction costs and construction periods. Flat roofs have more available space for installing photovoltaic modules or air-conditioning equipment.

[0004] However, when installing existing photovoltaic modules on a flat roof, it is necessary to first drill holes on the top of the flat roof and use an air pump to suck out the debris in the hole, so that the installation module can be fixed on the flat roof by bolts. However, drilling holes on the flat roof will damage the waterproof layer of the roof, and the roof needs to be waterproofed again; on the other hand, it will damage the structure of the roof, thereby reducing the load-bearing capacity of the roof; and in order to make full use of the space on the flat roof, the photovoltaic modules will be installed more densely, so as to maximize the available photovoltaic area; but dense photovoltaic modules are not conducive to maintenance personnel, and it is easy for maintenance personnel to step on the surface of the photovoltaic panels or apply excessive force, resulting in the risk of cracking and damage of the photovoltaic panels;

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 7 As shown, a high-current low-voltage photovoltaic assembly described in the present invention includes a photovoltaic panel 3 and a mounting assembly; the mounting assembly includes:

[0036] Base frame 1; the upper end of the base frame 1 is rotatably connected with a threaded tube 11; both ends of the threaded tube 11 are provided with support rods 111; the support rods 111 are connected with the threaded tube 11 in a spiral transmission manner; a connecting hole 112 is provided on the surface of the spiral tube; a mounting frame 2 is ball-jointed at the upper end of the base frame 1; the photovoltaic panel 3 is mounted on the mounting frame 2; an electric push rod 13 is hingedly connected to one side of the base frame 1; the end of the electric push rod 13 away from the base frame 1 is hingedly connected to the mounting frame 2; two adjacent photovoltaic panels 3 are connected via a connecting module;

[0037] Deflection module; the deflection module is mounted on the mounting frame 2; the deflection module is used to drive the photovoltaic panel 3 to deflect.

[0038] As an embodiment of the present invention, the two ends of the support rod 111 are fixedly connected with a concave block 12; the support rod 111 and the concave block 12 are fixedly connected by a support spring 121; the concave block 12 is made of polyimide material;

[0039] When installing existing photovoltaic modules on a flat roof, it is necessary to first drill holes on the top of the flat roof and use an air pump to suck out the debris in the hole, so that the installation module can be fixed to the flat roof by bolts. However, drilling holes in the flat roof will damage the waterproof layer of the roof on the one hand, and the roof needs to be waterproofed again; on the other hand, it will damage the structure of the roof, thereby reducing the load-bearing capacity of the roof; and in order to make full use of the space on the flat roof, the photovoltaic modules will be installed more densely, thereby maximizing the available photovoltaic area; but dense photovoltaic modules are not conducive to maintenance personnel, and it is easy for maintenance personnel to step on the surface of the photovoltaic panel 3 or apply too much force, resulting in the risk of cracking and damage of the photovoltaic panel 3;

[0040] When working, the user needs to first collect information such as the length and width of the flat roof of the installation site; and determine the length of the support rod 111 to be used according to the length of the flat roof in the east and west directions; before transporting the installation assembly to the installation site, it is necessary to insert the threaded ends of the required support rod 111 into the two ends of the spiral tube, at this time, the support rod 111 is slidably connected with the base frame 1, and the spiral tube is rotated so that the support rod 111 and the spiral tube rotate relative to each other, so that the threaded end of the support rod 111 continues to enter the spiral tube; so that the support rod 111 drives the concave block 12 to continuously approach the threaded tube 11; until the two support rods 111 contact each other inside the threaded tube 11, then stop rotating the spiral tube; at this time, the support rods 111 are The rod 111 is stored in the spiral tube, which is not only convenient for users to carry, but also saves users' installation time at the installation site. After the user places the base frame 1 on the flat roof, the user adjusts the position of the base frame 1 according to the direction, adjusts the axial direction of the spiral tube of the base frame 1 to the east or west, and then rotates the spiral tube in the opposite direction so that the support rods 111 at both ends of the spiral tube can spirally extend out of the spiral tube, so that the support rods 111 drive the concave block 12 to move away from the spiral tube until the concave block 12 contacts the edge of the flat roof, and then continues to rotate the spiral tube so that the spiral tube drives the support rods 111 to push the concave block 12 to press against the flat roof, so that the concave block 12 squeezes the support spring 121 under the push of the blocking force of the flat roof, so that The support rod 111 is allowed to enter the concave surface of the concave block 12 until the spiral tube cannot rotate. At this time, the concave block 12 is pushed by the restoring force of the spring and pressed against the edge of the flat roof. At this time, the user uses a hand drill to penetrate the connecting hole 112 so that the hand drill can punch a hole at the position of the support rod 111 opposite to the connecting hole 112. After the drilling is completed, the threaded tube 11 and the support rod 111 are fixed with rivets, and the spherical hinged joints on the mounting frame 2 and the base frame 1 are fixedly connected by bolts to realize the ball connection of the mounting frame 2 and the base frame 1, and then the electric push rod 13 is hinged between the mounting frame 2 and the base frame 1, and then the base frame 1 and the mounting frame 2 are arranged in sequence on the flat roof, and the photovoltaic panel 3 is installed on the mounting frame. On the mounting frame 2, the deflection module is installed on one side of the mounting frame 2 close to the electric push rod 13, and multiple mounting frames 2 are connected through the deflection module; and the connection module is used to connect the photovoltaic panels 3 on two adjacent mounting frames 2 in series; at this time, the photovoltaic assembly is installed; when the maintenance personnel need to inspect the photovoltaic assembly, the deflection module is controlled so that the deflection module drives the mounting frame 2 to deflect, so that the distance between the two adjacent mounting frames 2 is increased, so that it is convenient for the maintenance personnel to enter between the two mounting frames 2, and it is convenient for the maintenance personnel to inspect the photovoltaic panels 3 on the mounting frame 2; by setting the concave block 12 to be made of polyimide material; the concave block 12 has high hardness, wear resistance, high temperature resistance, and corrosion resistance;Thus, the high-hardness concave block 12 has a high strength, so that it can effectively support between the support rod 111 and the roof edge, ensuring that the support concave block 12 can be stably pressed between the support rod and the roof edge, and the characteristics of high temperature resistance, wear resistance and corrosion resistance can ensure that the concave block 12 on the roof can resist the erosion of dirt such as sunlight, wind and rain, thereby increasing the service life of the concave block 12;

[0041] The present invention cooperates between the spiral tube and the support rod 111, so that the support rod 111 can push the concave block 12 to press against the edge of the flat roof, avoiding the need to drill holes in the flat roof for installation. On the one hand, it can prevent damage to the waterproof layer on the flat roof, and there is no need to waterproof the flat roof, thereby reducing the installation cost; on the other hand, it can avoid damage to the roof structure and ensure the load-bearing capacity of the roof; and through the setting of the deflection module, the deflection of the mounting frame 2 and the photovoltaic panel 3 is achieved, which ensures that the photovoltaic components are installed densely while also facilitating maintenance personnel to inspect the photovoltaic panel 3 between the two mounting frames 2; thereby avoiding the risk of cracking or damage to the photovoltaic panel 3 caused by maintenance personnel stepping on the photovoltaic panel 3.

[0042] As an embodiment of the present invention, the deflection module includes:

[0043] There are two push plates 21; the two push plates 21 are parallel to each other; both sides of the mounting frame 2 are slidably connected to the push plates 21; there are two electric push rods 13; the two electric push rods 13 are distributed on both sides of the mounting frame 2; the two electric push rods 13 are respectively hinged at the lower ends of the two push plates 21;

[0044] A fixing unit is installed between the two push plates 21 ; the fixing unit is used to fix the two push plates 21 .

[0045] As an embodiment of the present invention, the fixing unit includes:

[0046] Insertion rod 211; a mounting groove 212 is provided on the surface of one of the push plates 21; the insertion rod 211 is slidably connected in the mounting groove 212; the insertion rod 211 and the groove bottom of the mounting groove 212 are fixedly connected by a connecting spring 213; a clamping groove 214 is provided on the surface of the insertion rod 211; a slot 215 facing the mounting groove 212 is provided on the surface of the other push plate 21;

[0047] The card strip 22, the inner wall of the slot 215 is provided with a groove 221 which is opposite to the card slot 214; the card strip 22 is slidably connected in the groove 221; a magnet 222 is fixedly connected to one end of the card strip 22 close to the groove 221; an electromagnetic sheet 223 is fixedly connected to the bottom of the groove 221;

[0048] When working, in the initial state, the two push plates 21 are parallel to each other, and the insertion rod 211 is opposite to the slot 215, so that the insertion rod 211 extends out of the installation slot 212 under the push of the connecting spring 213 and enters the slot 215, so that the insertion rod 211 contacts the bottom of the installation slot 212, so that the card slot 214 on the surface of the insertion rod 211 is opposite to the groove 221; at this time, the electromagnetic sheet 223 is in a powered state, and the magnetic pole of the electromagnetic sheet 223 is the same as the magnet 222, so that the magnet 222 drives the card strip 22 to move away from the electromagnetic sheet 223 under the action of the repulsive force, so that the card strip 22 can enter the card slot 214, so that The clamping strip 22 clamps the plug rod 211 in the slot 215; thereby the two push plates 21 are fixedly connected; during the day, when the photovoltaic component generates electricity, the two electric push rods 13 are controlled to be extended and retracted synchronously, so that the two electric push rods 13 can drive the mounting frame 2 to deflect in the east and west directions through the two connected push plates 21, so that the electric push rods 13 can push the mounting frame 2 to drive the photovoltaic panel 3 to deflect as the sun rises in the east and sets in the west, so that the photovoltaic panel 3 can always face the sun, thereby improving the photovoltaic power generation effect of the photovoltaic panel 3; and when the maintenance personnel need to inspect the photovoltaic component, first control the current in the electromagnetic sheet 223 to pass The direction changes, so that the electromagnetic sheet 223 generates a magnetic pole opposite to the magnet 222, so that the electromagnet 222 attracts the magnet 222 to drive the card strip 22 to extend out of the card slot 214 and enter the installation slot 212, so that the card strip 22 is separated from the insertion rod 211; then the electric push rod 13 connected to the upper push plate 21 is controlled to extend, and the electric push rod 13 connected to the lower push plate 21 is controlled to contract; so that the two push plates 21 are separated from each other, so that the lower push plate 21 drives the card strip 22 to extend out of the slot 215; the setting of the connecting spring 213 and the installation slot 212 is to prevent the insertion rod 211 from extending out of the slot 215 during the maintenance process. The plug rod 211 is exposed to the outside, so that when the plug rod 211 exposed to the outside is hit by a foreign object, the plug rod 211 can squeeze the connecting spring 213 into the installation groove 212 to avoid damage to the plug rod 211; due to the sliding connection between the push plate 21 and the mounting frame 2, the mounting plate can slide along the push plate 21 during the rise of the push plate 21, so that the mounting plate deflects in the south and north directions along the intersection of the base frame 1, so that the distance between the two adjacent mounting frames 2 is increased. At this time, the power supply of the photovoltaic power station is turned off, and the maintenance personnel can enter between the two deflected mounting frames 2, so as to realize the maintenance of the photovoltaic panels 3 on the mounting frames 2;

[0049] The present invention sets the insertion rod 211 so that the insertion rod 211 can fix the two push plates 21, thereby ensuring that the two push plates 21 are in contact with each other, and preventing the electric push rod 13 from pushing the two push plates 21 to drive the mounting frame 2 to deflect with the sun. The two push plates 21 are prevented from shaking and deflecting, thereby affecting the connection stability between the photovoltaic panels 3 on the mounting frame 2, thereby ensuring normal and stable power generation of the photovoltaic panels 3.

[0050] As an embodiment of the present invention, a slide groove 23 is provided on the inner wall of the mounting frame 2; the photovoltaic panel 3 is slidably connected in the slide groove 23; a baffle 231 is fixedly connected to the end of the mounting frame 2 away from the push plate 21; a buffer groove 232 is provided at the bottom of the slide groove 23; a buffer plate 233 is slidably connected in the buffer groove 232; the buffer plate 233 is fixedly connected in the buffer groove 232 by a fixing spring 234; an extrusion pad 235 is fixedly connected to the upper end wall of the slide groove 23; the extrusion pad 235 and the buffer plate 233 are both made of chloroprene rubber material.

[0051] As an embodiment of the present invention, a wave-shaped groove 236 is formed at one end of the compression pad 235 close to the buffer plate 233 ; and a gas dispersion groove 24 is formed inside the slide groove 23 .

[0052] As an embodiment of the present invention, one end of the gas dispersion groove 24 away from the slide groove 23 is inclined upward; two elastic sheets 25 are provided in the gas dispersion groove 24; one end of the elastic sheet 25 is fixedly connected to the inner wall of the gas dispersion groove 24; and the other end is fixedly connected to the notch of the gas dispersion groove 24 through a corrugated sheet 251;

[0053] During operation, in the initial state, the baffle plate 231 is not fixedly connected to the mounting frame 2; when installing the photovoltaic panel 3, the photovoltaic panel 3 is inserted from the end of the slide slot 23 away from the push plate 21, so that the photovoltaic panel 3 inserted into the slide slot 23 can squeeze the buffer plate 233 in the slide slot 23 into the buffer slot 232, so that the buffer plate 233 squeezes the fixing spring 234 into the buffer slot 232, and the photovoltaic panel 3 slides along the upper end surface of the buffer plate 233 until the photovoltaic panel 3 completely enters the slide slot 23, and the photovoltaic panel 3 is located at the end of the slide slot 23 close to the push plate 21; at this time, The baffle plate 231 is fixed to the end of the mounting frame 2 away from the push plate 21 by bolts, so that the baffle plate 231 is fixedly connected to the mounting frame 2, and the baffle plate 231 can block the photovoltaic panel 3 in the slide groove 23, so that the photovoltaic panel 3 is fixed on the mounting frame 2. At this time, the photovoltaic panel 3 is located between the extrusion pad 235 and the buffer plate 233; since the photovoltaic assembly is installed on the flat roof, it will be affected by the wind, so that the wind blows on the photovoltaic panel 3, causing mechanical vibration between the photovoltaic panel 3 and the mounting assembly, and this vibration will be transmitted to the photovoltaic panel 3 through the stiffness of the structure and the vibration conduction path. The interior of the photovoltaic cell 32; the photovoltaic cell 32 will have repeated loading and unloading cyclic stress under the action of continuous mechanical vibration, which will cause the photovoltaic cell 32 to suffer fatigue damage. Therefore, the squeezing pad 235 and the buffer plate 233 are made of chloroprene rubber material; the squeezing pad 235 and the buffer plate 233 made of chloroprene rubber material not only have good supporting effect and buffering effect; the good supporting effect can ensure the stable and effective connection between the photovoltaic panel 3 and the mounting frame 2, and the good buffering effect can reduce the mechanical vibration between the photovoltaic panel 3 and the mounting assembly, reduce the transmission of mechanical vibration to the interior of the photovoltaic cell 32, reduce the hazard of fatigue damage of the photovoltaic cell 32, and improve the service life of the photovoltaic cell 32. It also has excellent cold resistance and weather resistance, so that the squeezing pad 235 and the buffer plate 233 made of chloroprene rubber material can also have effective buffering and supporting performance in the cold winter in the north; and the strong wind will also put pressure on the packaging glass of the photovoltaic panel 3, causing the photovoltaic panel 3 to deform or crack under the blowing pressure of strong wind;Therefore, the encapsulation glass of the photovoltaic panel 3 is set to a slightly convex structure. While ensuring that the photovoltaic panel 3 can receive good light, the photovoltaic panel 3 can guide the wind to blow toward the chutes 23 on both sides of the photovoltaic panel 3 through the slightly convex structure, so that the wind guided by the photovoltaic panel 3 can enter the chutes 23 through the wavy grooves 236 of the squeezing pad 235, and be ejected through the air dispersion grooves 24 of the chutes 23. Since the end of the air dispersion groove 24 away from the chutes 23 is inclined upward, the gas ejected from the air dispersion groove 24 can hinder the wind blowing toward the photovoltaic panel 3, thereby reducing the wind pressure of the wind blowing toward the photovoltaic panel 3 from the outside, and through the elastic sheet 2 5, the two elastic sheets 25 can form an angle, so that the elastic sheet 25 reduces the distance between the notches of the air diffusion groove 24, increases the speed of the gas ejected from the air diffusion groove 24, and further increases the obstruction caused by the gas to the wind blowing toward the photovoltaic panel 3. When the wind force is strong, the wind pressure entering the air diffusion groove 24 will push the elastic sheet 25 to squeeze the corrugated sheet 251 to contract, so that the two elastic sheets 25 open, thereby accelerating the wind blowing toward the photovoltaic panel 3 to flow out of the air diffusion groove 24, increasing the conduction of the photovoltaic panel 3 to the wind pressure, reducing the wind pressure effect on the photovoltaic panel 3, and further protecting the service life of the packaging glass of the photovoltaic panel 3. ;

[0054] As an embodiment of the present invention, the connection module includes a connecting head 26; connecting ports 31 are opened on both sides of the photovoltaic panel 3; mounting ports 27 facing the connecting ports 31 are opened on both sides of the mounting frame 2; the connecting head 26 is threadedly connected in the mounting port 27 and connected to the connecting port 31.

[0055] As an embodiment of the present invention, a rectangular array of photovoltaic cells 32 is installed inside the photovoltaic panel 3; each row of the photovoltaic cells 32 is connected in series; the connection ports 31 on both sides of the photovoltaic panel 3 are opposite to the photovoltaic cells 32 in each column of the photovoltaic panel 3; the connection ports 31 of the photovoltaic panels 3 at both ends of the combined mounting frame 2 are connected to U-shaped parallel heads 33; the parallel heads 33 are used to connect two adjacent columns of cells in parallel;

[0056] When working, after the photovoltaic panel 3 is installed; the connection port 31 of the photovoltaic panel 3 is directly opposite to the installation port 27 of the mounting frame 2. At this time, the connector 26 needs to be inserted into the installation port 27, and the connector 26 is threadedly connected in the installation port 27 by rotating the connector 26, and one end of the connector 26 that passes through the installation port 27 is inserted into the connector 31. When the two mounting frames 2 are in the same plane, the connectors 26 on the two mounting frames 2 are connected by snapping. At this time, the photovoltaic cells 32 in the same row of the photovoltaic panels 3 on the two mounting frames 2 are in a series state. When the electric push rod 13 pushes the two push plates 21 away from each other, the push plates 21 push the two mounting frames 2 to flip over, so that the connectors 26 on the two mounting frames 2 are away from each other, so that the connectors 26 of the two mounting frames 2 are separated, so as to prevent leakage problems in the connected circuits caused by failure to turn off the power supply in time when repairing or cleaning the photovoltaic components, which makes the light The photovoltaic panel 3 is in a power-off protection state, and by connecting each row of photovoltaic cells 32 of the multiple groups of photovoltaic panels 3 connected in series in series, the series connection between the two photovoltaic panels 3 is ensured, and the number of photovoltaic cells 32 flowing through the current can be reduced, thereby reducing the current loss. The photovoltaic panel 3 is prone to the problem of uneven local illumination in cloudy weather, and connecting each row of photovoltaic cells 32 of the multiple groups of photovoltaic panels 3 connected in series in series can reduce the current change, thereby reducing the power generation power loss caused by shadow shading; and connecting two adjacent rows of photovoltaic cells 32 in parallel through the parallel head 33 can enable the two rows of cells in the array to share the light, further reducing the power loss caused by local shading. By connecting the photovoltaic cells 32 in the array in series and in parallel, it is not only conducive to maintaining a relatively stable output voltage; it also increases the power output capacity of the array, thereby maintaining a more stable and efficient photovoltaic array system.

[0057] The specific workflow is as follows:

[0058] When working, the user needs to first collect information such as the length and width of the flat roof of the installation site; and determine the length of the support rod 111 to be used according to the length of the flat roof in the east and west directions; before transporting the installation assembly to the installation site, it is necessary to insert the threaded ends of the required support rod 111 into the two ends of the spiral tube, at this time, the support rod 111 is slidably connected with the base frame 1, and the spiral tube is rotated so that the support rod 111 and the spiral tube rotate relative to each other, so that the threaded end of the support rod 111 continues to enter the spiral tube; so that the support rod 111 drives the concave block 12 to continuously approach the threaded tube 11; until the two support rods 111 contact each other inside the threaded tube 11, then stop rotating the spiral tube; at this time, the support rods 111 are The rod 111 is stored in the spiral tube, which is not only convenient for users to carry, but also saves users' installation time at the installation site. After the user places the base frame 1 on the flat roof, the user adjusts the position of the base frame 1 according to the direction, adjusts the axial direction of the spiral tube of the base frame 1 to the east or west, and then rotates the spiral tube in the opposite direction so that the support rods 111 at both ends of the spiral tube can spirally extend out of the spiral tube, so that the support rods 111 drive the concave block 12 to move away from the spiral tube until the concave block 12 contacts the edge of the flat roof, and then continues to rotate the spiral tube so that the spiral tube drives the support rods 111 to push the concave block 12 to press against the flat roof, so that the concave block 12 squeezes the support spring 121 under the push of the blocking force of the flat roof, so that The support rod 111 is allowed to enter the concave surface of the concave block 12 until the spiral tube cannot rotate. At this time, the concave block 12 is pushed by the restoring force of the spring and pressed against the edge of the flat roof. At this time, the user uses a hand drill to penetrate the connecting hole 112 so that the hand drill can punch a hole at the position of the support rod 111 opposite to the connecting hole 112. After the drilling is completed, the threaded tube 11 and the support rod 111 are fixed with rivets, and the spherical hinged joints on the mounting frame 2 and the base frame 1 are fixedly connected by bolts to realize the ball connection of the mounting frame 2 and the base frame 1, and then the electric push rod 13 is hinged between the mounting frame 2 and the base frame 1, and then the base frame 1 and the mounting frame 2 are arranged in sequence on the flat roof, and the photovoltaic panel 3 is installed on the mounting frame. On the mounting frame 2, the deflection module is installed on one side of the mounting frame 2 close to the electric push rod 13, and multiple mounting frames 2 are connected through the deflection module; and the connection module is used to connect the photovoltaic panels 3 on two adjacent mounting frames 2 in series; at this time, the photovoltaic assembly is installed; when the maintenance personnel need to inspect the photovoltaic assembly, the deflection module is controlled so that the deflection module drives the mounting frame 2 to deflect, so that the distance between the two adjacent mounting frames 2 is increased, so that it is convenient for the maintenance personnel to enter between the two mounting frames 2, and it is convenient for the maintenance personnel to inspect the photovoltaic panels 3 on the mounting frame 2; by setting the concave block 12 to be made of polyimide material; the concave block 12 has high hardness, wear resistance, high temperature resistance, and corrosion resistance;Thus, the high-hardness concave block 12 has a high strength, so that it can effectively support between the support rod 111 and the roof edge, ensuring that the support concave block 12 can be stably pressed between the support rod and the roof edge, and the characteristics of high temperature resistance, wear resistance and corrosion resistance can ensure that the concave block 12 on the roof can resist the erosion of dirt such as sunlight, wind and rain, thereby increasing the service life of the concave block 12;

[0059] In the initial state, the two push plates 21 are parallel to each other. At this time, the plug rod 211 is opposite to the slot 215, so that the plug rod 211 extends out of the installation slot 212 and enters the slot 215 under the push of the connecting spring 213, so that the plug rod 211 contacts the bottom of the installation slot 212, so that the slot 214 on the surface of the plug rod 211 is opposite to the groove 221; at this time, the electromagnetic sheet 223 is in a powered state, and the magnetic pole of the electromagnetic sheet 223 is the same as the magnet 222, so that the magnet 222 drives the clamping strip 22 to move away from the electromagnetic sheet 223 under the action of repulsion, so that the clamping strip 22 can enter the clamping slot 214, so that the clamping strip 22 clamps the plug rod 211 in the slot 215; thereby, the two push plates 21 are fixedly connected; during the day, the photovoltaic module generates electricity When the two electric push rods 13 are controlled to be extended and retracted synchronously, the two electric push rods 13 can drive the mounting frame 2 to deflect in the east and west directions through the two connected push plates 21, so that the electric push rods 13 can push the mounting frame 2 to drive the photovoltaic panel 3 to deflect as the sun rises in the east and sets in the west, so that the photovoltaic panel 3 can always face the sun, thereby improving the photovoltaic power generation effect of the photovoltaic panel 3; and when the maintenance personnel need to repair the photovoltaic component, first control the current passing direction in the electromagnetic sheet 223 to change, so that the electromagnetic sheet 223 produces a magnetic pole opposite to that of the magnet 222, so that the electromagnet 222 attracts the magnet 222 to drive the card strip 22 to extend out of the card slot 214 and enter the mounting slot 212, so that the card strip 22 is separated from the insertion rod 211; then control the upper The electric push rod 13 connected to the push plate 21 is extended, and the electric push rod 13 connected to the lower push plate 21 is contracted; the two push plates 21 are moved away from each other, so that the lower push plate 21 drives the card strip 22 to extend out of the slot 215; the setting of the connecting spring 213 and the mounting slot 212 is to prevent the insertion rod 211 from extending out of the slot 215 and being exposed to the outside during the maintenance process, so that when the insertion rod 211 exposed to the outside is hit by foreign objects, the insertion rod 211 can squeeze the connecting spring 213 into the mounting slot 212 to avoid damage to the insertion rod 211; due to the sliding connection between the push plate 21 and the mounting frame 2, the mounting plate can slide along the push plate 21 during the rise of the push plate 21, so that the mounting plate is deflected in the south and north directions along the intersection of the bottom frame 1 The photovoltaic panel 3 is rotated so that the distance between the two adjacent mounting frames 2 increases. At this time, the power supply of the photovoltaic power station is turned off, and the maintenance personnel can enter between the two deflected mounting frames 2, so as to realize the maintenance of the photovoltaic panel 3 on the mounting frame 2; in the initial state, the baffle plate 231 is not fixedly connected to the mounting frame 2; when the photovoltaic panel 3 is installed, the photovoltaic panel 3 is inserted from the end of the slide groove 23 away from the push plate 21, so that the photovoltaic panel 3 inserted into the slide groove 23 can squeeze the buffer plate 233 in the slide groove 23 into the buffer groove 232, so that the buffer plate 233 squeezes the fixing spring 234 into the buffer groove 232, and the photovoltaic panel 3 slides along the upper end surface of the buffer plate 233 until the photovoltaic panel 3 completely enters the slide groove 23, and the photovoltaic panel 3 is located at the end of the slide groove 23 close to the push plate 21;At this time, the baffle plate 231 is fixed to the end of the mounting frame 2 away from the push plate 21 by bolts, so that the baffle plate 231 is fixedly connected to the mounting frame 2, and the baffle plate 231 can block the photovoltaic panel 3 in the slide groove 23, so that the photovoltaic panel 3 is fixed on the mounting frame 2. At this time, the photovoltaic panel 3 is located between the extrusion pad 235 and the buffer plate 233; because the photovoltaic component is installed on the flat roof, it will be affected by the wind, so that the wind blows on the photovoltaic panel 3, causing mechanical vibration between the photovoltaic panel 3 and the mounting component, and this vibration will be transmitted to the inside of the photovoltaic cell 32 of the photovoltaic panel 3 through the stiffness of the structure and the vibration conduction path; so that the photovoltaic cell 32 will have repeated loading and unloading cyclic stress under the action of continuous mechanical vibration, thereby causing the photovoltaic In order to prevent the cell 32 from being damaged by fatigue, the squeezing pad 235 and the buffer plate 233 are made of chloroprene rubber material; the squeezing pad 235 and the buffer plate 233 made of chloroprene rubber material not only have good supporting effect and buffering effect; the good supporting effect can ensure the stable and effective connection between the photovoltaic panel 3 and the mounting frame 2, and the good buffering effect can reduce the mechanical vibration between the photovoltaic panel 3 and the mounting assembly, reduce the transmission of mechanical vibration to the inside of the photovoltaic cell 32, reduce the risk of fatigue damage to the photovoltaic cell 32, and increase the service life of the photovoltaic cell 32. In addition, the squeezing pad 235 and the buffer plate 233 made of chloroprene rubber material have excellent cold resistance and weather resistance, which makes the squeezing pad 235 and the buffer plate 233 made of chloroprene rubber material have good cold resistance and weather resistance in the north. The photovoltaic panel 3 has effective buffering and supporting performance even in the cold winter; and the strong wind force will also produce pressure on the packaging glass of the photovoltaic panel 3, causing the photovoltaic panel 3 to deform or have hidden cracks under the blowing pressure of the strong wind; therefore, the packaging glass of the photovoltaic panel 3 is set to a slightly convex structure, while ensuring that the photovoltaic panel 3 can receive good light, the photovoltaic panel 3 can guide the wind to blow toward the chute 23 on both sides of the photovoltaic panel 3 through the slightly convex structure, so that the wind guided by the photovoltaic panel 3 can enter the chute 23 through the wavy groove 236 of the extrusion pad 235, and be ejected through the air dispersion groove 24 of the chute 23. Since the air dispersion groove 24 is inclined upward at one end away from the chute 23, the gas ejected from the air dispersion groove 24 can resist the wind blowing toward the photovoltaic panel 3 The wind pressure of the wind blowing toward the photovoltaic panel 3 from the outside is reduced, and the two elastic sheets 25 can form an angle through the setting of the elastic sheet 25, so that the elastic sheet 25 reduces the distance between the notches of the air diffusion groove 24, increases the speed of the gas ejected from the air diffusion groove 24, and thus increases the obstruction caused by the gas to the wind blowing toward the photovoltaic panel 3. When the wind force is strong, the wind pressure entering the air diffusion groove 24 will push the elastic sheet 25 to squeeze the corrugated sheet 251 to contract, so that the two elastic sheets 25 open, thereby accelerating the wind blowing toward the photovoltaic panel 3 to flow out from the air diffusion groove 24, increasing the conduction of the photovoltaic panel 3 to the wind pressure, reducing the wind pressure effect on the photovoltaic panel 3, and thus protecting the service life of the packaging glass of the photovoltaic panel 3; after the photovoltaic panel 3 is installed;The connection port 31 of the photovoltaic panel 3 is directly opposite to the installation port 27 of the mounting frame 2. At this time, the connector 26 needs to be inserted into the installation port 27. By rotating the connector 26, the connector 26 is threadedly connected in the installation port 27, and one end of the connector 26 that passes through the installation port 27 is inserted into the connection port 31. When the two mounting frames 2 are in the same plane, the connectors 26 on the two mounting frames 2 are connected by snapping. At this time, the same row of photovoltaic cells 32 of the photovoltaic panels 3 on the two mounting frames 2 are in a series state. When the electric push rod 13 pushes the two push plates 21 away from each other, the push plates 21 push the two mounting frames 2 to flip, so that the connectors 26 on the two mounting frames 2 are away from each other, so that the connectors 26 of the two mounting frames 2 are separated, so as to prevent leakage problems in the connected circuits caused by failure to turn off the power supply in time when repairing or cleaning the photovoltaic components, so that the photovoltaic panels 3 are in a power-off state. Protection state, and by connecting each row of photovoltaic cells 32 of the multiple groups of photovoltaic panels 3 connected in series in series, that is, ensuring the series connection between two photovoltaic panels 3, it can also reduce the number of photovoltaic cells 32 that flow through the current, reduce the current loss, and the photovoltaic panel 3 is prone to uneven local illumination in cloudy weather, and connecting each row of photovoltaic cells 32 of the multiple groups of photovoltaic panels 3 in series in series can reduce the change of current, thereby reducing the power loss caused by shadow shading; and connecting two adjacent rows of photovoltaic cells 32 in parallel through the parallel head 33 can make the two rows of cells in the array share the light, further reducing the power loss caused by local shading, and by connecting the photovoltaic cells 32 in the array in series and in parallel, it is not only conducive to maintaining a relatively stable output voltage; it also increases the power output capacity of the array, thereby maintaining a more stable and efficient photovoltaic array system. ;
