Description

Technical Field

[0001] This utility model relates to the field of inverter installation technology, specifically to a photovoltaic inverter installation structure. Background Technology

[0002] The photovoltaic inverter is one of the core components of a photovoltaic power generation system. When installing the inverter onto the surface of the photovoltaic panel support column, a combination of a crossbeam and a U-shaped clamp is used. During installation, the U-shaped clamp is wrapped around the rear of the support column, passes through the crossbeam located at the front of the column, and is secured by tightening nuts. The clamping force generated by the nuts forces the U-shaped clamp to adhere tightly to the surface of the support column. The photovoltaic inverter is typically fixed to the front of the crossbeam using bolts or clips.

[0003] However, the clamping force of this structure depends on the tightening force of the nuts on both arms of the U-shaped clamp. Photovoltaic inverters are usually installed outdoors. The influence of the external environment and factors such as vibration can easily cause the fastening nuts to gradually loosen over time. As a result, the contact pressure between the beam and the front surface of the support column, and between the U-shaped clamp and the rear surface of the support column will weaken. Before the staff regularly inspects and maintains the equipment, the connection will always be in a loose state. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a photovoltaic inverter installation structure to solve the issue of loosening at the connection points of the crossbeams and U-shaped clamps used for fixing the photovoltaic inverter over time.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a photovoltaic inverter installation structure, including an inverter body, a crossbeam and a U-shaped clamp, and also including a side pressure rod, a transmission gear set and a lower pressure rod. The crossbeam is fixedly installed on the rear side of the inverter body, and the U-shaped clamp is fixedly installed on the rear side of the crossbeam. The transmission gear set is provided on the rear side of the inverter body. There are two sets of side pressure rods, which are slidably installed on the upper and lower sides of the transmission gear set. The lower pressure rod is slidably installed on the bottom of the transmission gear set.

[0006] The transmission gear set includes a fixing component and a gear component. The fixing component is fixedly installed on the rear side of the inverter body and is slidably connected to the side pressure rod and the lower pressure rod respectively. The gear component is slidably sleeved onto the surface of the fixing component and is meshed with the side pressure rod and the lower pressure rod respectively.

[0007] The side pressure rod includes a clamping rod and a first clamping plate. An L-shaped plate is fixedly installed on the front side of the clamping rod. One end of the L-shaped plate is connected to the first clamping plate. There are two sets of side pressure rods, and the two sets of side pressure rods are arranged symmetrically about the transmission gear set.

[0008] The clamping rod is fixedly installed with baffles at both ends, and the surface of the first clamping plate is provided with a first sliding groove.

[0009] The fixing components of the transmission gear set include a fixing seat, a rotating shaft, a first slider, and a second slider. The fixing seat is fixedly installed on the rear side of the inverter body. The rotating shaft is fixedly installed on the rear side of the fixing seat. A connecting plate is fixedly installed on the free end of the rotating shaft. The first slider is fixedly installed on the front side of the connecting plate. The second slider is fixedly installed on the rear side of the inverter body.

[0010] The gear components of the transmission gear set include a first transmission wheel and a second transmission wheel. The first transmission wheel is slidably sleeved on the surface of the rotating shaft, and the second transmission wheel is slidably sleeved on the surface of the rotating shaft. A protrusion is installed on the rear side of the second transmission wheel, and the protrusion is inserted into the front side of the first transmission wheel.

[0011] The pressing rod includes a second card plate and a storage frame. A connecting rod is fixedly installed at the bottom of the second card plate, and the connecting rod is fixedly connected to the storage frame.

[0012] The surface of the bottom connecting rod of the second card plate is provided with a second sliding groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention adds counterweights to the storage frame, causing the second clamping plate to move under the guidance of the second slider. This causes the second transmission wheel, which meshes with the second clamping plate, to rotate. The insertion of the second transmission wheel into the first transmission wheel causes the first transmission wheel to rotate. Relying on the meshing of the first transmission wheel with the first clamping plate, the two sets of first clamping plates move in opposite directions. The traction clamping rod adheres to the left and right sides of the U-shaped clamp. Thus, when the crossbeam and U-shaped clamp are fixing the inverter body, even if the nuts loosen over time, the clamping rod can apply pressure from both sides to the U-shaped clamp, clamping it tightly and increasing the force it receives. This prevents the contact pressure between the crossbeam and the U-shaped clamp on the support column from weakening, maintaining a stable installation effect of the crossbeam and U-shaped clamp on the inverter body before the staff inspects the equipment.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 5 The present invention will be further described below.

[0023] A photovoltaic inverter installation structure includes an inverter body 1, a crossbeam 2, and a U-shaped clamp 3. It also includes a side pressure rod 4, a transmission gear set 5, and a lower pressure rod 6. The crossbeam 2 is fixedly installed on the rear side of the inverter body 1, and the U-shaped clamp 3 is fixedly installed on the rear side of the crossbeam 2. The crossbeam 2 and the U-shaped clamp 3 are respectively attached to the front and rear sides of the photovoltaic panel support column. The transmission gear set 5 is provided on the rear side of the inverter body 1. There are two sets of side pressure rods 4, which are slidably installed on the upper and lower sides of the transmission gear set 5. The lower pressure rod 6 is slidably installed on the bottom of the transmission gear set 5. The transmission gear set 5 includes a fixing component and gear components. The fixing component is fixedly installed on the rear side of the inverter body 1 and is slidably connected to the side pressure rod 4 and the lower pressure rod 6. The gear components are slidably sleeved onto the surface of the fixing component and are meshed with the side pressure rod 4 and the lower pressure rod 6.

[0024] Specifically, the inverter body 1 is fixed to the surface of the photovoltaic panel support column by connecting the crossbeam 2 and the U-shaped clamp 3. The transmission gear set 5 enables the transmission of power between the lower pressure rod 6 and the side pressure rod 4. The lower pressure rod 6 applies downward pressure to the transmission gear set 5, which is transmitted to the side pressure rod 4, causing the two sets of side pressure rods 4 to move in opposite directions.

[0025] The side pressure rod 4 includes a clamping rod 401 and a first clamping plate 402. An L-shaped plate is fixedly installed on the front side of the clamping rod 401. One end of the L-shaped plate is connected to the first clamping plate 402. The first clamping plate 402 is meshed with the first transmission wheel 503. There are two sets of side pressure rods 4, and the two sets of side pressure rods 4 are centrally symmetrical about the transmission gear set 5.

[0026] Specifically, the two symmetrical side pressure rods 4 enable the first transmission wheel 503 to rotate, thereby driving the two sets of first clamping plates 402 to move synchronously towards each other and pushing the two sets of clamping rods 401 closer to the surface of the U-shaped clamp 3.

[0027] The clamping rod 401 has baffles fixedly installed at both ends, and the surface of the first clamping plate 402 has a first sliding groove, which is slidably connected to the first slider 505.

[0028] Specifically, by having the baffles adhere to the upper and lower sides of the crossbeam 2, the movement of the clamping rod 401 becomes more stable. The first groove of the first clamping plate 402 is slidably connected to the transmission gear set 5, guiding the first clamping plate 402 to move stably.

[0029] The fixing components of the transmission gear set 5 include a fixing seat 501, a rotating shaft 502, a first slider 505, and a second slider 506. The fixing seat 501 is fixedly installed on the rear side of the inverter body 1. The rotating shaft 502 is fixedly installed on the rear side of the fixing seat 501. A connecting plate is fixedly installed on the free end of the rotating shaft 502. The first slider 505 is fixedly installed on the front side of the connecting plate. The second slider 506 is fixedly installed on the rear side of the inverter body 1 and is located below the fixing seat 501.

[0030] Specifically, the first sliding block 505 guides the first plate 402 to move horizontally in a stable manner, and the second sliding block 506 guides the second plate 601 to move vertically in a stable manner.

[0031] The gear components of the transmission gear set 5 include a first transmission wheel 503 and a second transmission wheel 504. The first transmission wheel 503 is slidably sleeved on the surface of the rotating shaft 502, and the second transmission wheel 504 is slidably sleeved on the surface of the rotating shaft 502. A protrusion is installed on the rear side of the second transmission wheel 504, and the protrusion is inserted into the front side of the first transmission wheel 503.

[0032] Specifically, the engagement of the second transmission wheel 504 with the lower pressure rod 6 causes the lower pressure rod 6 to move downward, thereby rotating the second transmission wheel 504. The engagement of the first transmission wheel 503 with the side pressure rod 4 causes the rotation of the first transmission wheel 503 to move the side pressure rod 4 horizontally. The protrusion causes the rotation of the second transmission wheel 504 to drive the first transmission wheel 503 to rotate synchronously.

[0033] The pressure rod 6 includes a second card plate 601 and a storage frame 602. A connecting rod is fixedly installed at the bottom of the second card plate 601, and the connecting rod is fixedly connected to the storage frame 602.

[0034] Specifically, counterweights are stored in the storage box 602, thereby applying a downward pulling force to the second plate 601 via the connecting rod.

[0035] The surface of the bottom connecting rod of the second card plate 601 is provided with a second sliding groove, and the second sliding groove is slidably connected to the second slider 506.

[0036] Specifically, the second card plate 601 is slidably connected to the transmission gear set 5 through the second groove of the second card plate 601, which guides the second card plate 601 to move stably.

[0037] In summary: When using this utility model, the operator installs the inverter body 1 onto the surface of the photovoltaic panel support column and adds counterweights or heavy objects into the storage frame 602. Over time, the nuts at the connection between the crossbeam 2 and the U-shaped clamp 3 become loose. At this point, the contact pressure between the crossbeam 2 and the U-shaped clamp 3 against the support column should weaken. However, because the storage frame 602 applies downward pressure to the second clamping plate 601, when the U-shaped clamp 3 shifts and loosens, the second clamping plate 601 and the connecting rod move downward along the surface of the second slider 506. The second clamping plate 601 drives the second transmission wheel 504, which meshes with it, to rotate. The protrusion of the second transmission wheel 504 is inserted into the first transmission wheel 503, thereby driving the first transmission wheel 503 to rotate synchronously. The first transmission wheel 503 drives the first clamping plate 402 that meshes with it to move. The two sets of first clamping plates 402 move horizontally towards each other along the surface of the first slider 505. The first clamping plate 402 drives the clamping rod 401 to move, so that the clamping rod 401 applies pressure to the left and right sides of the U-shaped clamp 3, tightening the U-shaped clamp 3 to increase its contact pressure with the support column. When the crossbeam 2 and the U-shaped clamp 3 become loose, the installation of the device is kept stable before the staff inspects the equipment and performs maintenance.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
