Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically, to an intelligent suspended transport vehicle for photovoltaic inverters. Background Technology

[0002] Photovoltaic power generation is a clean energy technology that uses the photovoltaic effect to directly convert solar radiation energy into electrical energy. The core is to convert light energy into direct current through photovoltaic modules, and then process it through equipment such as inverters and distribution boxes to achieve self-use or grid connection. It is one of the core directions of global new energy transformation.

[0003] According to existing technology, in order to convert direct current (DC) to alternating current (AC) during photovoltaic (PV) power generation, PV inverters are installed in PV power plants. PV inverters also ensure system stability. PV inverters have a certain weight, and transportation equipment is needed for handling. When installing PV inverters in PV power plants in reed marshes, small boats are required for transportation. Traditional PV inverters have dedicated transportation equipment. Since dedicated transportation equipment is generally used on land, although it has a certain vibration reduction and buffering capacity, the large swaying amplitude during transportation on small boats results in insufficient vibration reduction, leading to damage to the PV inverters due to impacts. Summary of the Invention

[0004] This invention provides an intelligent suspended transport tool for photovoltaic inverters. The distance between two placement plates can be adjusted via a main threaded rod and a knob, accommodating inverters of different sizes and ensuring secure clamping. An airbag inside the placement plate covers the inverter surface; when inflated, it conforms to the equipment, effectively absorbing vibrations and impacts during transport. The polyurethane rubber layer of the airbag not only enhances the cushioning effect but also reduces wear on the airbag itself. This solves the problem mentioned in the background section: while specialized transport equipment generally has some vibration damping capacity, it is insufficient when transported on small boats due to large swaying amplitudes, leading to damage to the photovoltaic inverter from impacts.

[0005] To achieve the above objectives, a smart suspended transport tool for a photovoltaic inverter includes a converter, a support frame, and a hanging device. The support frame is located on one side of the converter, and four support rods are fixedly connected to the side wall of the support frame. The hanging device is disposed on the surface of the converter and includes two fixed plates located at the upper and lower ends of the converter, respectively. The inner wall of the fixed plate is slidably connected to the surface of the two support rods, and two elastic ropes are fixedly connected to the surface of the fixed plate.

[0006] Two elastic ropes are fixedly connected to a placement plate at their ends away from the fixed plate. The placement plate is sleeved on the surface of the converter. Two main threaded rods are threadedly connected to the inner walls of the two placement plates. Knobs are threadedly connected to the surfaces of the main threaded rods.

[0007] The surface of the support frame is provided with two limiting devices, each including a sleeve rod inserted into the inner surface of the support frame, and the limiting devices are used to limit the support frame.

[0008] The support frame is provided with a support device, which includes two support plates inserted into the inner surface of the support frame, and four support rods are divided into two groups and inserted into the inner surfaces of the two support plates respectively. The support device can support the two support rods.

[0009] In the above technical solution, a gasket is fixedly connected to the surface of the main threaded rod. The gasket is located on the surface of the upper placement plate, and the knob is located on the surface of the lower placement plate. An airbag is inserted into the inner surface of the placement plate. The surface of the airbag is provided with a polyurethane rubber layer. The airbag is fitted onto the surface of the converter. A valve core is fixedly connected to the surface of the airbag. The valve core is inserted into the inner surface of the placement plate. A positioning bolt is threadedly connected to the inner wall of the fixing plate and the support rod.

[0010] Secondly, the surface of the support frame is provided with multiple slots, the sleeve is inserted into the inner surface of the slots of the support frame, the inner wall of the sleeve is threaded with two auxiliary threaded rods, the side wall of the auxiliary threaded rod is rotatably connected with a top plate, the surface of the auxiliary threaded rod is fixedly connected with a turntable, and the inner walls of the support frame and the sleeve are threaded with multiple limit bolts.

[0011] Furthermore, based on the above, a limiting groove is formed on the surface of the support frame near the support plate, the support plate is inserted into the inner surface of the limiting groove of the support frame, the support frame and the inner walls of the two support plates are threadedly connected to a main rod, the inner walls of the two support plates and the inner walls of the two support rods are threadedly connected to a secondary rod, a locking hole is formed on the surface of the support plate near the support rod, the support rod is inserted into the inner surface of the locking hole of the support plate, and a side plate is fixedly connected to the side wall of the support plate.

[0012] Meanwhile, protective devices are provided on both sides of the support frame. The protective devices include a guard plate located on one side of the support frame. The guard plate and the inner wall of the support frame are threadedly connected with two mounting bolts. A storage plate is fixedly connected to the side wall of the support frame. A locking strip is fixedly connected to the side wall of the guard plate and inserted into the inner surface of the storage plate. A tilt sensor, a controller, and an alarm light are fixedly connected to the upper surface of the support frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] In this intelligent suspended transport vehicle for photovoltaic inverters, the distance between the two placement plates can be adjusted via a main threaded rod and a knob, accommodating converters of different sizes and ensuring a secure clamping of the converter. The airbags inside the placement plates fit snugly against the converter surface after inflation, effectively absorbing vibrations and impacts during transport. The polyurethane rubber layer of the airbags not only enhances the cushioning effect but also reduces wear on the airbags themselves. Elastic ropes also assist in cushioning, preventing damage to the core components of the converter due to bumps. Protective devices on both sides of the support frame provide lateral protection through guard plates, preventing external objects from impacting the support frame and converter during transport.

[0028] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] Since specialized conveying equipment is generally used for land transportation, although it has a certain vibration reduction and buffering capacity, when transported on small boats, the large swaying amplitude can lead to insufficient vibration reduction, resulting in damage to the photovoltaic inverters due to impacts.

[0030] Therefore, in view of the above-mentioned problems, the present invention provides an intelligent suspended transport tool for a photovoltaic inverter. Referring to Figures 1-3, it includes an inverter 1, a support frame 2, and a hanging device 4. The support frame 2 is located on one side of the inverter 1, and four support rods 3 are fixedly connected to the side wall of the support frame 2. The four-point support can improve the stability of the overall structure. The hanging device 4 is set on the surface of the inverter 1. The hanging device 4 includes two fixing plates 41 located at the upper and lower ends of the inverter 1, respectively. The inner wall of the fixing plate 41 is slidably connected to the surface of the two support rods 3. Two elastic ropes 42 are fixedly connected to the surface of the fixing plate 41. The fixing plate 41 can connect the elastic ropes 42 and the support rods 3. The end of the two elastic ropes 42 away from the fixing plate 41 is fixedly connected to a placement plate 43. The placement plate 43 is sleeved on the surface of the inverter 1. It has good buffering and shock absorption performance, and can absorb the impact force from the outside during hoisting, reducing the damage to converter 1 caused by vibration;

[0031] Two main threaded rods 44 are threadedly connected to the inner walls of the two placement plates 43. A knob 45 is threadedly connected to the surface of the main threaded rods 44, and a washer 46 is fixedly connected to the surface of the main threaded rods 44. The washer 46 is located on the surface of the upper placement plate 43, and the knob 45 is located on the surface of the lower placement plate 43. By rotating the knob 45, the distance between the two placement plates 43 can be precisely adjusted to achieve a firm clamping of the converter 1. An airbag 47 is inserted into the inner surface of the placement plate 43. After the airbag 47 is inflated, it can tightly wrap the converter 1. The elasticity of the gas can achieve all-round buffer protection to avoid scratches, bumps and other damage to the surface of the converter 1. The surface of the airbag 47 is covered with a polyurethane rubber layer. The airbag 47 is fitted on the surface of the converter 1. The polyurethane rubber layer has excellent wear resistance and pressure resistance, which can effectively protect the airbag 47 from friction damage and extend the service life of the airbag 47.

[0032] A valve core 48 is fixedly connected to the surface of the airbag 47. The valve core 48 is inserted into the inner surface of the placement plate 43. The design of the valve core 48 facilitates the inflation and deflation of the airbag 47, making it easy to install and disassemble the device. It also allows for adjustment of the inflation volume. The inner walls of the fixing plate 41 and the support rod 3 are threadedly connected to a positioning bolt 49. The positioning bolt 49 restricts the position of the fixing plate 41 on the surface of the support rod 3.

[0033] refer to Figure 4-5 As shown, the surface of the support frame 2 is provided with two limiting devices 5. Through the design of the double limiting structure, the hoisting position of the converter 1 can be precisely constrained from both sides. The limiting device 5 includes a sleeve rod 51 inserted into the inner surface of the support frame 2. The surface of the support frame 2 is provided with multiple slots 52. The sleeve rod 51 is inserted into the inner surface of the slots 52 of the support frame 2. The slots 52 can store the sleeve rod 51 in the inner surface of the support frame 2.

[0034] The inner wall of the sleeve rod 51 is threaded with two auxiliary threaded rods 53. The side wall of the auxiliary threaded rod 53 is rotatably connected to a top plate 54. The surface of the auxiliary threaded rod 53 is fixedly connected to a turntable 55. Rotating the turntable 55 causes the auxiliary threaded rod 53 to move along the inner wall of the sleeve rod 51, which in turn pushes the top plate 54 to move. The top plate 54 will press against the inner surface of the hull, thereby achieving the effect of limiting the position of the support frame 2. The inner wall of the support frame 2 and the sleeve rod 51 are threaded with multiple limit bolts 56. The limit bolts 56 can firmly lock the sleeve rod 51 and the support frame 2 to prevent the sleeve rod 51 from shifting due to vibration or force during the hoisting process.

[0035] refer to Figure 6-7As shown, the surface of the support frame 2 is provided with a support device 6, which can support the support rods 3 and effectively disperse the pressure generated during the hoisting of the converter 1. The support device 6 includes two support plates 61 inserted into the inner surface of the support frame 2. The four support rods 3 are divided into two groups and inserted into the inner surfaces of the two support plates 61 respectively, which can more stably support the weight of the converter 1, reduce the risk of swaying during hoisting, and provide a more reliable support foundation for the converter 1. A limiting groove 62 is opened on the surface of the support frame 2 near the support plate 61. The support plate 61 is inserted into the inner surface of the limiting groove 62 of the support frame 2. The limiting groove 62 can play a positioning role for the installation position of the support plate 61 and prevent the support plate 61 from shifting during installation.

[0036] The support frame 2 and the inner walls of the two support plates 61 are threaded with main rods 63. The main rods 63 can firmly lock the two support plates 61 and the support frame 2 into a whole, thereby improving the structural integrity and rigidity of the support device 6. The inner walls of the two support plates 61 and the inner walls of the two support rods 3 are threaded with auxiliary rods 64, which can strengthen the fixing effect between the two and prevent the support rods 3 from loosening or shifting. The surface of the support plate 61 is provided with a locking hole 65 near the support rod 3. The support rod 3 is inserted into the inner surface of the locking hole 65 of the support plate 61. The locking hole 65 can limit the position of the support rod 3 and ensure the accuracy of the installation position of the support rod 3. The side wall of the support plate 61 is fixedly connected with a side plate 66. The side plate 66 can reduce the situation where branches and leaves in the reed marsh scrape the support plate 61, and at the same time guide the branches and leaves.

[0037] refer to Figure 8-9 As shown, protective devices 7 are provided on both sides of the support frame 2. The symmetrical design on both sides can form protection from the left and right sides of the converter 1 to prevent external objects from colliding with the converter 1 during hoisting. The protective device 7 includes a guard plate 71, which is located on one side of the support frame 2. The guard plate 71 is made of solid plate structure and has good impact resistance and scratch resistance, which can directly block the impact of external forces on the converter 1.

[0038] The inner wall threaded connection between the guard plate 71 and the support frame 2 has two mounting bolts 72. The fixing method of the double mounting bolts 72 can ensure the firmness of the connection between the guard plate 71 and the support frame 2. The side wall of the support frame 2 is fixedly connected to a storage plate 73, and the side wall of the guard plate 71 is fixedly connected to a retaining strip 74. The retaining strip 74 is inserted into the inner surface of the storage plate 73. The insertion and removal of the retaining strip 74 and the storage plate 73 can play an auxiliary positioning role for the guard plate 71, while sharing the force of the mounting bolts 72 and reducing the load on the threaded connection.

[0039] Referring to Figure 10, an tilt sensor 8, a controller 9, and an alarm light 10 are fixedly connected to the upper surface of the support frame 2. The three work together to achieve a safety monitoring effect, monitor the attitude status of the support frame 2 and the converter 1 in real time during transportation, improve the safety of the overall hoisting operation from the perspective of proactive early warning, and reduce safety accidents caused by equipment tilting to a certain extent.

[0040] The working principle of this invention is as follows: two placement plates 43 are placed on the surface of the converter 1. By rotating the knob 45 of the lower placement plate 43, the knob 45 rotates on the surface of the main thread rod 44. The knob 45 precisely adjusts the distance between the two placement plates 43. The gasket 46 will press against the surface of the upper placement plate 43. The two placement plates 43 are tightly attached to the upper and lower ends of the converter 1 to achieve initial clamping. The air bladder 47 inside the placement plate 43 is inflated through the valve core 48. After inflation, the air bladder 47 tightly wraps the surface of the converter 1 and forms a buffer layer by utilizing the elasticity of the gas. The fixing plate 41 is then placed on the surface of the support rod 3.

[0041] After the fixed plate 41 is moved to the appropriate position, the positioning bolt 49 is rotated to the inner wall of the fixed plate 41 and the support rod 3. During the installation of the fixed plate 41, the elastic rope 42 is kept taut. After the fixed plate 41 is installed, the two support plates 61 are inserted into the support frame 2 through the limiting groove 62. The main rod 63 is used to lock the support plate 61 and the support frame 2 into a whole. The four support rods 3 are divided into two groups and inserted into the support plate 61 through the locking hole 65. Then, the auxiliary rod 64 is used to fix the support rods 3 and the support plate 61 to strengthen the connection rigidity. The side plate 66 on the side wall of the support plate 61 can reduce the scratching of the reed branches and leaves, and at the same time guide the branches and leaves to make the device move more smoothly.

[0042] The side guard plates 71 are fixed to the support frame 2 by mounting bolts 72. The retaining strips 74 of the guard plates 71 are inserted into the storage plate 73 to assist in positioning and share the force of the mounting bolts 72. Then, the sleeve rod 51 is inserted into the inner surface of the slot 52 of the support frame 2. Then, the limiting bolt 56 is rotated to the inner wall of the support frame 2 and the sleeve rod 51. The rotating turntable 55 drives the auxiliary threaded rod 53 to move, pushing the top plate 54 to press against the inner wall of the ship's interior, thus restricting the overall position of the support frame 2 from both sides to prevent displacement during transportation.

[0043] During transportation, the tilt sensor 8 on the support frame 2 monitors the device's posture in real time and transmits the data to the controller 9. When the tilt angle exceeds the preset safety threshold, the controller 9 immediately triggers the alarm light 10 to issue a warning to the operator, prompting them to adjust the transportation posture in time, thereby reducing the risk of safety accidents from the perspective of proactive warning.

[0044] After the transport arrives at the destination, the gas in the airbag 47 is released through the valve core 48, then the knob 45 is rotated in the opposite direction to loosen the main thread rod 44, widening the spacing of the placement plate 43, and then the converter 1 is taken out.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
