Description

Technical Field

[0001] This invention belongs to the field of inverter technology, specifically a photovoltaic grid-connected inverter. Background Technology

[0002] Photovoltaic grid-connected inverters provide various power conversion and access solutions for various renewable energy power generation systems such as solar photovoltaic power generation, wind power generation, fuel cell power generation, and small hydropower generation. They are mainly used in renewable energy grid-connected power generation systems, off-grid village power supply systems, and household power systems, and can also provide power for communication, transportation, and street lighting in areas where grid extension is difficult.

[0003] A patent application with publication number CN113890095A discloses a photovoltaic grid-connected system, including a base box, a support plate, solar panels, an adjustment mechanism, a mounting mechanism, a controller, a connecting support base, and a base door. The upper end of the base box is fixedly connected to the support plate, which is L-shaped. A solar panel is hinged to the support plate, and an adjustment mechanism is provided on the support plate. The mounting mechanism is located inside the base box, and a connecting support base is fixedly connected to the lower end of the base box. A base door is hinged to the base box. This invention relates to a photovoltaic grid-connected system and a photovoltaic grid-connected inverter, and features convenient adjustment of the solar panels.

[0004] The above technical solution solves the problem of inconvenient adjustment of solar panels through the adjustment mechanism. However, there are still some problems when using the inverter. Since the inverter is used outdoors and the inverter's connecting wires do not have clamping devices, the wires may sway to a certain extent when the wind is strong. Over time, the wires at the connection of the inverter body may become loose. Moreover, the wires are not neatly arranged and are tangled and messy.

[0005] Therefore, the present invention provides a photovoltaic grid-connected inverter. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A photovoltaic grid-connected inverter of this invention includes an inverter body; multiple wire seats are fixedly connected to the lower surface of the inverter body; a support frame is rotatably connected to the lower side of the inverter body; a rotating shaft adapted to the support frame is provided on the lower side of the inverter body; a cable management plate is fixedly connected to the side surface of the support frame near the wire seats; multiple cable management grooves are formed on the surface of the cable management plate; the multiple cable management grooves are equally spaced on the surface of the cable management plate. Because the inverter is used outdoors and the inverter's connecting wires do not have clamping devices, when the external environment is windy, the wires may sway to a certain extent due to the wind force. Over time, the connection points of the inverter body may become loose. Furthermore, the wires are currently not neatly arranged, which... To address the issue of tangled and disordered wire distribution, this invention addresses the problem of wires being tangled and disordered under the inverter body when organizing the inverter's wires using the wire guide. Wires at different locations are passed through the wire management grooves on the surface of the wire management plate, allowing the grooves to arrange and fix the wires at different locations. This prevents the wires from being tangled and disordered under the inverter body, ensuring they are arranged at equal intervals. This solves the problem of difficult repairs caused by the tangled and disordered distribution of wires under the inverter body in existing technologies. It also improves the stability of the wires during use, reducing the risk of wires coming loose at connections in strong winds. Furthermore, it solves the problem of tangled wires affecting heat dissipation, extending the lifespan of the wires. Additionally, it allows for the accurate and quick location of each wire, facilitating the use of the inverter body.

[0008] Preferably, a first annular plate is fixedly connected to the inner wall of each cable management groove; the first annular plate is semi-circular in shape; an adsorption plate is fixedly connected to the inner wall of the first annular plate; the number of adsorption plates on the surface of a single first annular plate is multiple, and they are fixedly connected to the inner wall of the first annular plate at equal intervals; the adsorption plate is made of sponge; during operation, when the wire passes through the cable management groove, the wire will come into contact with the adsorption plate on the inner wall of the cable management groove. At this time, the adsorption plate made of sponge can adsorb and remove moisture and some impurities on the surface of the wire, so as to avoid moisture affecting its lifespan.

[0009] Preferably, the surface of the cable management plate has a limiting groove; a movable frame is slidably connected to the surface of the cable management plate and inside the limiting groove; a connecting rod is fixedly connected to the surface of the movable frame; a second annular plate is fixedly connected to the surface of the connecting rod; multiple second annular plates are provided and are respectively arranged inside the cable management groove; each second annular plate is arranged in a one-to-one correspondence with a first annular plate; an adsorption plate is provided on the inner wall of each second annular plate; when the wire passes through the inside of the cable management groove and is connected to other equipment, the operator pulls the movable frame, causing the movable frame to move the connecting rod. The connecting rod at different positions will move the second annular plates at different locations closer to the first annular plate. Then the second annular plate will engage with the first annular plate, so that the first annular plate and the second annular plate press and clamp the wires at different locations, improving the stability of the wires during use and reducing the problem of wires falling off at different connection points when there is strong wind, thus ensuring the normal use of the inverter body.

[0010] Preferably, each of the first annular plates has an embedding groove on its surface; each of the second annular plates has an embedding rod fixedly connected to its surface; the shape of the embedding rod and the embedding groove are adapted to each other; during operation, when the first annular plate and the second annular plate are combined, the embedding rod on the surface of the second annular plate will be inserted into the embedding groove on the surface of the first annular plate, which improves the stability of the clamping of the wire by the first annular plate and the second annular plate and makes it more convenient to use.

[0011] Preferably, a mounting plate is fixedly connected to the surface of the inverter body and the side near the support frame; a connecting frame is fixedly connected inside the mounting plate; a rotating shaft is provided inside the connecting frame; a support column is rotatably connected to the lower end of the rotating shaft; the bottom end of the support column is connected to the side surface of the support frame; a rotating groove adapted to the rotating shaft is provided on the outer surface of the support column; an elastic locking rod is fixedly connected to the outer surface of the rotating shaft; a locking groove is opened on the surface of the connecting frame; the shape of the elastic locking rod and the shape of the locking groove are adapted to each other; during operation, after the wires are connected to other equipment, the operator first pulls the rotating shaft, causing the rotating shaft to move the support column, which in turn causes the support frame and the cable management plate to rotate at a certain angle below the inverter body. Then, the cable management plate will move towards the side near the wire seat, so that the cable management grooves at different locations on the surface of the cable management plate press against the surfaces of different wires, thereby limiting and fixing the position of the wires.

[0012] Preferably, a support base is fixedly connected to the outer surface of the wire holder; the number of support bases on a single wire holder surface is two, and they are symmetrically arranged; each support base has an installation groove on its surface; a rotating shaft is fixedly connected inside each support base and located in the installation groove; an inclined rod is rotatably connected to the outer surface of the rotating shaft; a tightening plate is fixedly connected to the top of the inclined rod; the tightening plate is semi-circular in shape, which can cooperate with the arc shape of the wire surface, thereby facilitating its pressure on the wire. During operation, when the support frame and the wire management plate are rotated above the wire holder by the operator, the wire management plate will press against the inclined rod of the support base on the wire holder surface. The inclined rods on both sides will rotate at a certain angle under pressure, and then the inclined rod will drive the tightening plate to abut against the outside of the wire, which can further fix the connected wire and can adapt to wires of different diameters, thus improving its application range.

[0013] Preferably, a limiting plate is fixedly connected to the surface of the support base; an elastic vertical rod is fixedly connected to the lower surface of the limiting plate; the lower end of the elastic vertical rod is connected to the upper surface of the tilting rod; during operation, when the tilting rod rotates under the pressure of the cable management plate, the tilting rod will press against the elastic vertical rod on its upper surface, and this elastic vertical rod will provide the tilting rod with a certain supporting force and buffering force, which facilitates the tilting rod and the tightening plate to press against the surface of the wire.

[0014] Preferably, the surface of the tightening plate has a through groove; each tightening plate has two through grooves arranged symmetrically; each tightening plate has a slidingly connected pressing post inside the through groove; a compression spring is fixedly connected to the outer surface of the pressing post; the surface of the tightening plate has multiple cylindrical grooves, each cylindrical groove and through groove being arranged in a one-to-one correspondence; an abutment rod is rotatably connected inside the tightening plate inside the cylindrical groove; an abutment head is fixedly connected to the top of the abutment rod, the abutment head being arc-shaped to facilitate pressing against the arc-shaped surface of the wire; during operation, when the external environment is windy, the wire inside the tightening plate will... The conductor sways to a certain extent, which puts pressure on the pressure column inside the tightening plate. Under pressure, the pressure column and compression spring move towards the contact rod within the through slot, pushing the contact rod. Since the contact rod is rotatably connected inside the tightening plate, it rotates at a certain angle when subjected to the pressure of the pressure column. This causes the contact head to move towards the conductor, further securing the conductor in windy conditions. This reduces the risk of the conductor loosening at the inverter connection point due to prolonged swaying. The stronger the wind, the higher the pressure of the contact rod, facilitating the connection between the conductor and the inverter and making the inverter easier to use.

[0015] Preferably, the inverter body has heat dissipation grooves on its surface; an electric telescopic rod is fixedly connected inside the inverter body; a baffle plate is rotatably connected to the outer surface of the inverter body at the heat dissipation grooves; multiple baffle plates are provided, each baffle plate corresponding to a heat dissipation groove; a top rod is slidably connected inside the inverter body at the heat dissipation grooves; multiple arc-shaped seats are fixedly connected to the outer surface of the electric telescopic rod; multiple arc-shaped seats and top rods are corresponding to each other; during normal use, the baffle plate is in a flipped state, and the heat dissipation grooves are not exposed. The shielding is provided, and the top rod presses against one side of the shielding plate. When the external environment is rainy, the electric telescopic rod and its surface arc seat are moved synchronously by controlling the electric telescopic rod. Then the arc seat will contact and press against one end of the top rod, and the top rod will move away from the shielding plate. At this time, the shielding plate is no longer pressed and will rotate at a certain angle. Then the shielding plate will press against the surface of the heat dissipation trough, blocking the heat dissipation trough and reducing the problem of some rainwater entering the inverter body through the heat dissipation trough, thus reducing the problem of rainwater affecting the use of some components in the inverter body.

[0016] Preferably, the top rod is arc-shaped on the side near the arc-shaped seat; the inverter body has a sliding groove inside that matches the top rod; during operation, the arc-shaped top rod facilitates the pressing between the arc-shaped seat and the top rod, thereby facilitating the interaction between the top rod and the baffle plate, allowing the baffle plate to be in a flipped or closed state.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The photovoltaic grid-connected inverter of the present invention arranges and fixes the wires at different locations through cable management channels, avoiding the wires from being tangled and messy under the inverter body. This allows the wires to be arranged at equal intervals, solving the problem of difficult operation during repair due to the tangled and messy distribution of wires under the inverter body in the prior art. It also improves the stability of the wires during use, reduces the problem of wires easily falling off at different connection points in strong winds, and solves the problem of heat dissipation being affected by tangled wires, thus improving the service life of the wires. Furthermore, it allows for the accurate and quick location of each wire, facilitating the use of the inverter body.

[0019] 2. The photovoltaic grid-connected inverter of the present invention involves an arc-shaped base that contacts and presses against one end of a top rod. The top rod moves away from the shielding plate, at which point the shielding plate is no longer pressed and rotates at a certain angle. Consequently, the shielding plate presses against the surface of the heat dissipation trough, blocking the heat dissipation trough and reducing the problem of some rainwater entering the inverter body through the heat dissipation trough, thus reducing the problem of rainwater affecting the use of some components in the inverter body.

[0020] 3. The photovoltaic grid-connected inverter of the present invention uses a contact rod to move the contact head closer to the conductor, which can further fix the conductor in windy weather, reducing the problem of the conductor easily becoming loose at the connection between the conductor and the inverter under long-term shaking. Moreover, the stronger the wind, the higher the pressure of the contact rod will be, which facilitates the connection between the conductor and the inverter and makes the use of the inverter more convenient.

Detailed Implementation

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figures 1 to 2 As shown in the embodiment of the present invention, a photovoltaic grid-connected inverter includes an inverter body 1; a plurality of wire seats 2 are fixedly connected to the lower surface of the inverter body 1; a support frame 3 is rotatably connected to the lower side of the inverter body 1; a rotating rod adapted to the support frame 3 is provided on the lower side of the inverter body 1; a cable management plate 4 is fixedly connected to the side surface of the support frame 3 near the wire seats 2; a plurality of cable management grooves 5 are formed on the surface of the cable management plate 4; the plurality of cable management grooves 5 are equally spaced on the surface of the cable management plate 4; since the inverter is used outdoors and the inverter's connecting wires do not have a clamping device, when the external environment is windy, the wires may sway to a certain extent due to the wind force. Over time, the wires at the inverter connection points may become loose, and currently the wires are not neatly arranged and are intertwined. To address the issue of haphazard wire distribution, this invention addresses the problem of wires being tangled and scattered beneath the inverter body 1 when using the wire connector 2 to manage the wires. Wires at different locations are passed through the wire management grooves 5 on the surface of the wire management plate 4, allowing the grooves 5 to arrange and fix the wires at different locations. This prevents the wires from being tangled and scattered below the inverter body 1, ensuring they are arranged at equal intervals. This solves the problem in the prior art where the tangled and scattered wires below the inverter body 1 make repair difficult, improves the stability of the wires during use, reduces the risk of wires detaching at connection points in strong winds, and also solves the problem of tangled wires affecting heat dissipation, thus extending the lifespan of the wires. Furthermore, it allows for the accurate and quick location of each wire, facilitating the use of the inverter body 1.

[0038] like Figures 2 to 3As shown, each of the cable management grooves 5 has a first annular plate 6 fixedly connected to its inner wall; the first annular plate 6 is semi-circular in shape; an adsorption plate 7 is fixedly connected to the inner wall of the first annular plate 6; the number of adsorption plates 7 on the surface of a single first annular plate 6 is multiple, and they are fixedly connected to the inner wall of the first annular plate 6 at equal intervals; the adsorption plate 7 is made of sponge; during operation, when the wire passes through the cable management groove 5, the wire will come into contact with the adsorption plate 7 on the inner wall of the cable management groove 5. At this time, the sponge material adsorption plate 7 can adsorb and remove moisture and some impurities on the surface of the wire, preventing moisture from affecting its lifespan.

[0039] The cable management plate 4 has a limiting groove 8 on its surface; a movable frame 9 is slidably connected to the surface of the cable management plate 4 and inside the limiting groove 8; a connecting rod 10 is fixedly connected to the surface of the movable frame 9; a second annular plate 11 is fixedly connected to the surface of the connecting rod 10; multiple second annular plates 11 are provided and are respectively arranged inside the cable management groove 5; each second annular plate 11 is arranged in a one-to-one correspondence with a first annular plate 6; an adsorption plate 7 is provided on the inner wall of each second annular plate 11; when the wire passes through the inside of the cable management groove 5 and is connected to other equipment, the operator pulls the movable frame 9, causing the movable frame 9 to move the connecting rod 10. The connecting rod 10 at different positions will move the second annular plates 11 at different locations closer to the first annular plate 6. Then the second annular plates 11 will combine with the first annular plate 6, so that the first annular plate 6 and the second annular plate 11 press and clamp the wires at different locations, which improves the stability of the wires during use and reduces the problem of wires falling off at different locations when there is strong wind, thus ensuring the normal use of the inverter body 1.

[0040] like Figures 3 to 6 As shown, each of the first annular plates 6 has an embedding groove 12 on its surface; each of the second annular plates 11 has an embedding rod 13 fixedly connected to its surface; the shapes of the embedding rod 13 and the embedding groove 12 are adapted to each other; during operation, when the first annular plate 6 and the second annular plate 11 are combined with each other, the embedding rod 13 on the surface of the second annular plate 11 will be inserted into the embedding groove 12 on the surface of the first annular plate 6, which improves the stability of the clamping of the wire by the first annular plate 6 and the second annular plate 11, and is more convenient to use.

[0041] A mounting plate 14 is fixedly connected to the surface of the inverter body 1 and the side near the support frame 3; a connecting frame 15 is fixedly connected inside the mounting plate 14; a rotating shaft 16 is provided inside the connecting frame 15; a support column 17 is rotatably connected to the lower end of the rotating shaft 16; the bottom end of the support column 17 is connected to the side surface of the support frame 3; a rotating groove adapted to the rotating shaft 16 is provided on the outer surface of the support column 17; an elastic locking rod 18 is fixedly connected to the outer surface of the rotating shaft 16; the connecting frame 1... The surface of 5 is provided with a slot 19; the shape of the elastic lever 18 is adapted to the shape of the slot 19; during operation, after the wires are connected to other equipment, the operator first pulls the rotating shaft 16, so that the rotating shaft 16 drives the support column 17 to move. The support column 17 drives the support frame 3 and the cable management plate 4 to rotate at a certain angle below the inverter body 1. Then the cable management plate 4 will move to the side closer to the wire seat 2, so that the cable management grooves 5 at different places on the surface of the cable management plate 4 press on the surface of different wires, thereby limiting and fixing the position of the wires.

[0042] like Figures 7 to 10 As shown, a support base 20 is fixedly connected to the outer surface of the wire seat 2; there are two support bases 20 on the surface of each wire seat 2, and they are arranged symmetrically; each support base 20 has an installation groove on its surface; a rotating shaft 201 is fixedly connected inside each support base 20 and located in the installation groove; an inclined rod 202 is rotatably connected to the outer surface of the rotating shaft 201; a tightening plate 203 is fixedly connected to the top of the inclined rod 202; the tightening plate 203 is semi-circular in shape, which can cooperate with the arc of the wire surface, thereby facilitating its pressure on the wire. During operation, when the support frame 3 and the wire management plate 4 are rotated above the wire seat 2 by the operator, the wire management plate 4 will press against the inclined rod 202 of the support base 20 on the surface of the wire seat 2. The inclined rods 202 on both sides will rotate at a certain angle under pressure, and then the inclined rods 202 will drive the tightening plate 203 to abut against the outside of the wire, which can further fix the connected wire and can adapt to wires of different diameters, thus improving its application range.

[0043] A limiting plate 204 is fixedly connected to the surface of the support base 20; an elastic vertical rod 205 is fixedly connected to the lower surface of the limiting plate 204; the lower end of the elastic vertical rod 205 is connected to the upper surface of the tilting rod 202; during operation, when the tilting rod 202 rotates under the pressure of the cable management plate 4, the tilting rod 202 will press against the elastic vertical rod 205 on its upper surface. This elastic vertical rod 205 will provide the tilting rod 202 with a certain supporting force and buffering force, which makes it easier for the tilting rod 202 and the tightening plate 203 to press against the surface of the wire.

[0044] The surface of the tightening plate 203 is provided with a through groove; each tightening plate 203 has two through grooves arranged symmetrically; each tightening plate 203 has a slidingly connected a pressure post 206 inside the through groove; a compression spring 207 is fixedly connected to the outer surface of the pressure post 206; the surface of the tightening plate 203 is provided with multiple cylindrical grooves, each cylindrical groove and through groove being arranged in a one-to-one correspondence; an abutment rod 208 is rotatably connected inside the tightening plate 203 inside the cylindrical groove; an abutment head 209 is fixedly connected to the top of the abutment rod 208, the abutment head 209 being arc-shaped to facilitate pressing the arc-shaped surface of the wire; during operation, when the external environment is windy, the wire inside the tightening plate 203 will be... The slight swaying causes the conductor to exert pressure on the pressure post 206 inside the tightening plate 203. Under pressure, the pressure post 206 and compression spring 207 move towards the contact rod 208 within the through slot, pushing the contact rod 208. Since the contact rod 208 is rotatably connected inside the tightening plate 203, it rotates at a certain angle when subjected to pressure from the pressure post 206. This causes the contact head 209 to move towards the conductor, further securing the conductor in windy conditions. This reduces the risk of the conductor becoming loose at the inverter connection point due to prolonged swaying. Furthermore, the stronger the wind, the higher the pressure exerted by the contact rod 208, facilitating the connection between the conductor and the inverter and making the inverter easier to use.

[0045] Example 2

[0046] like Figure 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a heat dissipation groove 101 is formed on the surface of the inverter body 1; an electric telescopic rod 21 is fixedly connected inside the inverter body 1; a baffle plate 22 is rotatably connected to the outer surface of the inverter body 1 at the heat dissipation groove 101; multiple baffle plates 22 are provided, and each baffle plate 22 is arranged in a one-to-one correspondence with the heat dissipation groove 101; a top rod 23 is slidably connected inside the inverter body 1 at the heat dissipation groove 101; multiple arc-shaped seats 24 are fixedly connected to the outer surface of the electric telescopic rod 21; multiple arc-shaped seats 24 are arranged in a one-to-one correspondence with the top rod 23; during normal use, the baffle plate 22... In the flipped state, the heat sink 101 is not blocked, and the top rod 23 presses against one side of the shielding plate 22. When the external environment is rainy, by controlling the electric telescopic rod 21, the electric telescopic rod 21 and the arc-shaped seat 24 on its surface move synchronously. Then the arc-shaped seat 24 will contact and press against one end of the top rod 23. The top rod 23 will move away from the shielding plate 22. At this time, the shielding plate 22 is no longer pressed and will rotate at a certain angle. Then the shielding plate 22 will press against the surface of the heat sink 101, blocking the heat sink 101. This reduces the problem of some rainwater entering the inverter body 1 through the heat sink 101 and reduces the problem of rainwater affecting the use of some components in the inverter body 1.

[0047] The top rod 23 is arc-shaped on the side near the arc-shaped seat 24; the inverter body 1 is provided with a sliding groove that matches the top rod 23; during operation, the arc-shaped top rod 23 can facilitate the pressing of the arc-shaped seat 24 and the top rod 23, thereby facilitating the interaction between the top rod 23 and the baffle plate 22, so that the baffle plate 22 is in a flipped or closed state.

[0048] During operation, when organizing the wires of the inverter body 1 through the wire connector 2, wires at different positions are passed through the wire management grooves 5 on the surface of the wire management plate 4. The wire management grooves 5 arrange and fix the wires at different locations, preventing them from being tangled and messy under the inverter body 1. This ensures the wires are evenly spaced, solving the problem of difficult repair due to the tangled and messy distribution of wires under the inverter body 1 in existing technologies. It also improves the stability of the wires during use, reducing the risk of wires falling off at different connection points in strong winds. Furthermore, it solves the problem of tangled wires affecting heat dissipation, extending the lifespan of the wires. It also allows for accurate and quick location of each wire, facilitating the use of the inverter body 1. As the wires pass through the wire management grooves 5, they come into contact with the adsorption plates 7 on the inner wall of the grooves 5. At this time, the sponge-material adsorption plates 7 can absorb moisture and some of the water from the wire surface. Impurities are adsorbed and removed to prevent moisture from affecting its lifespan. When the wires pass through the cable management groove 5 and are connected to other equipment, the operator pulls the movable frame 9, which moves the connecting rod 10. The connecting rod 10 at different positions moves the second annular plate 11 at different locations closer to the first annular plate 6. Then, the second annular plate 11 and the first annular plate 6 are combined, so that the first annular plate 6 and the second annular plate 11 press and clamp the wires at different locations, which improves the stability of the wires during use and reduces the problem of wires falling off at different connection points when there is strong wind. This ensures the normal use of the inverter body 1. When the first annular plate 6 and the second annular plate 11 are combined, the embedded rod 13 on the surface of the second annular plate 11 will be inserted into the embedded groove 12 on the surface of the first annular plate 6, which improves the stability of the clamping of the wires by the first annular plate 6 and the second annular plate 11 and makes it more convenient to use.

[0049] After the wires are connected to other equipment, the operator first pulls the rotating shaft 16, causing the rotating shaft 16 to move the support column 17. The support column 17 causes the support frame 3 and the cable management plate 4 to rotate at a certain angle below the inverter body 1. Then, the cable management plate 4 will move towards the side closer to the wire seat 2, so that the cable management grooves 5 at different locations on the surface of the cable management plate 4 press against the surfaces of different wires, thus limiting and fixing the position of the wires. When the support frame 3 and the cable management plate 4 are rotated above the wire seat 2 by the operator, the cable management plate 4 will press against the inclined rod 202 of the support seat 20 on the surface of the wire seat 2. The inclined rods 202 on both sides will rotate at a certain angle under pressure, and then the inclined rods 202 will drive the tightening plate 203 to abut against the outside of the wire, which can further fix the connected wires and can adapt to wires of different diameters, thus improving its application range. When the inclined rod 202 rotates under the pressure of the cable management plate 4, the inclined rod 202 will press against the elastic vertical rod 205 on its upper surface. 5 will provide a certain supporting force and buffering force to the tilting rod 202, which will facilitate the tilting rod 202 and the tightening plate 203 to press against the surface of the conductor. When the external environment is windy, the conductor inside the tightening plate 203 will sway to a certain extent, and the conductor will exert a certain pressure on the pressing column 206 inside the tightening plate 203. The pressing column 206 and the compression spring 207 will be compressed and will move towards the side of the contact rod 208 in the through groove, pushing the contact rod 208. Due to the rotation of the contact rod 208, Since it is connected inside the tightening plate 203, the abutment rod 208 will rotate at a certain angle when it is subjected to the pressure of the abutment column 206. In turn, the abutment rod 208 will drive the abutment head 209 to move closer to the conductor. This can further fix the conductor in windy weather, reduce the problem of the conductor easily becoming loose at the connection with the inverter after long-term shaking. Moreover, the stronger the wind, the higher the abutment force of the abutment rod 208 will be, which facilitates the connection between the conductor and the inverter and makes the use of the inverter more convenient.

[0050] During normal use, the shield 22 is in a flipped state, not blocking the heat dissipation slot 101, and the top rod 23 presses against one side of the shield 22. When the external environment is rainy, by controlling the electric telescopic rod 21, the electric telescopic rod 21 and the arc-shaped seat 24 on its surface move synchronously. Then, the arc-shaped seat 24 will contact and press against one end of the top rod 23, and the top rod 23 will move away from the shield 22. At this time, the shield 22 is no longer pressed and will rotate at a certain angle. Then, the shield 22 will press against the surface of the heat dissipation slot 101, blocking the heat dissipation slot 101 and reducing the problem of some rainwater entering the inverter body 1 through the heat dissipation slot 101, thus reducing the problem of rainwater affecting the use of some components in the inverter body 1. The arc-shaped top rod 23 can facilitate the pressing between the arc-shaped seat 24 and the top rod 23, thereby facilitating the cooperation between the top rod 23 and the shield 22, so that the shield 22 is in a flipped or closed state.
