Description

Technical Field

[0001] This invention belongs to the field of photovoltaic equipment maintenance technology, and in particular relates to a safety device for preventing electric shock during photovoltaic equipment maintenance. Background Technology

[0002] Photovoltaic equipment maintenance electric shock safety devices refer to the general term for special protective facilities and equipment used in the inspection and maintenance of live equipment such as photovoltaic power station components, inverters, and combiner boxes to isolate live areas, prevent personnel from accidentally touching live parts, and reduce the risk of electric shock.

[0003] The spatial form of photovoltaic power plant operating areas is highly diverse. For example, there are no uniform standards for parameters such as the spacing of single-row photovoltaic modules, the installation spacing between inverters and combiner boxes, and the boundary dimensions of photovoltaic arrays of different specifications. Traditional electric shock safety devices generally adopt a fixed length design, making it difficult to flexibly adjust the enclosure size according to the actual working area on site. This leads to two types of core safety hazards: If the length of the safety device is less than the perimeter of the target isolation area, it will directly create a protective gap, causing live parts such as the metal frame of the photovoltaic module and the junction box terminals to be exposed outside the protection range, greatly increasing the risk of electric shock accidents caused by personnel accidentally entering the live area.

[0004] If the length of the safety device exceeds the perimeter of the target isolation area, the excess part needs to be adapted to the installation space by means of forced bending, stacking, etc. This can easily cause structural deformation of the device and loosening of the connection parts, thereby reducing its overall structural strength. At the same time, uneven installation will destroy the stability of the device, and it is very easy to cause the risk of overturning under the action of external forces such as outdoor wind, further losing the isolation and protection function. In view of this, we propose a photovoltaic equipment maintenance electric shock safety device. Summary of the Invention

[0005] The purpose of this invention is to provide a safety device for preventing electric shock during the maintenance of photovoltaic equipment, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a safety device for preventing electric shock during the maintenance of photovoltaic equipment, comprising: The first support rod has two first sleeves fixedly connected to its periphery. Each of the two first sleeves has a first groove that communicates with the outside. Each of the two first grooves has a first connecting rod slidably connected to it. One end of each of the two first connecting rods is fixedly connected to a first fixing rod. A plurality of second sleeves are fixedly connected to the periphery of the first support rod. Each of the plurality of second sleeves has a second sliding groove that communicates with the outside. Each of the plurality of second sliding grooves is slidably connected to a second connecting rod. One end of each of the plurality of second connecting rods is fixedly connected to a second fixing rod. A second support rod is fixedly connected between the plurality of second fixing rods and two first fixing rods. An adjustment assembly is located between the first support rod and the two first sleeves and is used to move the two first connecting rods.

[0007] In this technical solution, users can adjust the length of the overall device, allowing it to flexibly adapt to installation requirements.

[0008] In the above technical solution, the adjustment component further includes: Two screws, each screw being threadedly connected to two first connecting rods; Two gear slots are formed in the first support rod and are respectively connected to the two first fixed rods. A first bevel gear and a second bevel gear are rotatably connected in both gear slots and the first bevel gear and the second bevel gear mesh with each other. One end of each of the two first bevel gears extends into the two first sliding grooves and is respectively fixedly connected to the two screws. A rotating groove is formed inside the first support rod and communicates with two gear grooves. A third connecting rod is rotatably connected inside the rotating groove, and the two ends of the third connecting rod extend into the two gear grooves and are fixedly connected to the two second bevel gears respectively. A through groove is formed on the inner wall of one of the gear grooves and is connected to the outside. A rotating rod is rotatably connected in the through groove, and one end of the rotating rod extends into one of the gear grooves and is fixedly connected to one end of a third connecting rod.

[0009] In this technical solution, it is ensured that the user can control the simultaneous movement of the two first connecting rods.

[0010] Furthermore, the above technical solution also includes: A plurality of fixed blocks are fixedly connected to the top surface of the first support rod, and each of the fixed blocks is rotatably connected to a pressing block, and the pressing block is in contact with the rotating rod. An extrusion assembly, located on a rotating rod, is used to extrude a plurality of extrusion blocks.

[0011] In this technical solution, the rotating rod is ensured to rotate under external influences, thereby improving the overall stability of the device.

[0012] In the above technical solution, the extrusion assembly further includes: A threaded groove is formed on the circumference of the rotating rod, and a threaded sleeve is threadedly connected to the threaded groove. The bottom surface of the threaded sleeve is provided with an extrusion groove.

[0013] In this technical solution, it is ensured that several extrusion blocks can be extruded simultaneously.

[0014] In the above technical solution, further, the top ends of the plurality of extrusion blocks are all inclined, and the top ends of the plurality of extrusion blocks are inserted into the extrusion groove.

[0015] In this technical solution, since the tops of several extrusion blocks are all inclined, when the inner wall of the extrusion groove presses the tops of several extrusion blocks, the several extrusion blocks can rotate in the direction of the rotating rod, and ensure that when the threaded sleeve drives the extrusion groove to move downward to the appropriate position, the tops of several extrusion blocks can be inserted into the extrusion groove.

[0016] In the above technical solution, further, the threads on the two screws have the same direction of rotation and the same thread pitch, and the screws are located in the first groove and are rotatably connected to the first groove.

[0017] In this technical solution, because the threads on the two screws have the same direction of rotation and the same thread pitch, when the two screws rotate, the two first connecting rods will be acted upon by the threads of the two screws and move simultaneously along the two first sliding grooves, ensuring that the screws can rotate normally within the first sliding grooves when they rotate.

[0018] In the above technical solution, one end of the first bevel gear is rotatably connected to the first sliding groove, and both ends of the third connecting rod are rotatably connected to the two gear grooves respectively.

[0019] In this technical solution, it is ensured that when the first bevel gear rotates, one end of the first bevel gear can rotate normally in the first slide groove, and it is also ensured that when the third connecting rod rotates, both ends of the third connecting rod can rotate normally in the two gear grooves respectively.

[0020] In the above technical solution, one end of the rotating rod is rotatably connected to one of the gear slots, and the circumference of the rotating rod is provided with anti-slip texture.

[0021] In this technical solution, it is ensured that when the rotating rod rotates, one end of the rotating rod can rotate normally in one of the gear slots. Furthermore, because the rotating rod is provided with anti-slip texture on its periphery, when the rotating rod is rotated by hand, it will be affected by the anti-slip texture, which will increase the friction between the hand and the rotating rod and reduce the occurrence of hand slippage.

[0022] The beneficial effects of this invention are: 1. This photovoltaic equipment maintenance and electric shock safety device, through the arrangement of a first support rod, a first sleeve, a first slide groove, a first connecting rod, a first fixing rod, a second sleeve, a second slide groove, a second connecting rod, a second fixing rod, and a second support rod, allows the user to adjust the distance between the first support rod and the second support rod. Through the arrangement of a gear groove, a first bevel gear, a second bevel gear, a rotating groove, a third connecting rod, a through groove, a rotating rod, and a screw, the user can simultaneously drive two screws to rotate, allowing the two first connecting rods to drive the second support rod to move via the two first fixing rods. The design of this structure enables adjustment of the overall device length, preventing the safety device from being too long or too short, and improving the overall device's adaptability and isolation protection function.

[0023] 2. The photovoltaic equipment maintenance and electric shock safety device uses a fixed block and a pressing block to allow the pressing block to rotate on the fixed block. The threaded groove, threaded sleeve, and pressing groove allow the threaded sleeve to drive the pressing groove to press several pressing blocks. The design of the above structure allows several pressing blocks to clamp and fix the rotating rod, preventing the rotating rod from rotating due to external influences, thereby improving the stability of the overall device.

[0026] The following is in conjunction with the appendix Figure 1 - Figure 8 This application will be described in further detail.

[0028] Example 1: This example provides a safety device for preventing electric shock during photovoltaic equipment maintenance, including: The first support rod 1 has two first sleeves 2 fixedly connected to its periphery. Each of the two first sleeves 2 has a first groove 3 that communicates with the outside. Each of the two first grooves 3 has a first connecting rod 4 slidably connected to it. One end of each of the two first connecting rods 4 is fixedly connected to a first fixing rod 5. A plurality of second sleeves 6 are fixedly connected to the periphery of the first support rod 1. Each of the plurality of second sleeves 6 has a second sliding groove 7 that communicates with the outside. Each of the plurality of second sliding grooves 7 is slidably connected to a second connecting rod 8. One end of each of the plurality of second connecting rods 8 is fixedly connected to a second fixing rod 9. A second support rod 10 is fixedly connected between the plurality of second fixing rods 9 and the two first fixing rods 5. An adjustment assembly is located between the first support rod 1 and the two first sleeves 2, and is used to move the two first connecting rods 4.

[0029] In use, the user adjusts the components to move the two first connecting rods 4 along the two first sliding grooves 3, which in turn move the second support rods 10 via the two first fixed rods 5, moving the second support rods 10 away from the first support rods 1. As the second support rods 10 move, they pull the second connecting rods 8 along the second sliding grooves 7 via the second fixed rods 9, ensuring that the user can adjust the length of the entire device and flexibly adapt it to installation requirements.

[0030] Example 2: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features, and the adjustment component includes: Two screws 23 are threadedly connected to the two first connecting rods 4 respectively; Two gear slots 11 are formed in the first support rod 1 and are respectively connected to the two first fixed rods 5. A first bevel gear 12 and a second bevel gear 13 are rotatably connected in both gear slots 11, and the first bevel gear 12 and the second bevel gear 13 mesh with each other. One end of the two first bevel gears 12 extends into the two first sliding grooves 3 and is respectively fixedly connected to the two screws 23. A rotating groove 14 is formed inside the first support rod 1 and is connected to two gear grooves 11. A third connecting rod 15 is rotatably connected inside the rotating groove 14, and the two ends of the third connecting rod 15 extend into the two gear grooves 11 and are fixedly connected to the two second bevel gears 13 respectively. A through groove 16 is formed on the inner wall of one of the gear grooves 11 and is connected to the outside. A rotating rod 17 is rotatably connected inside the through groove 16, and one end of the rotating rod 17 extends into one of the gear grooves 11 and is fixedly connected to one end of the third connecting rod 15.

[0031] In use, the user manually rotates the rotating rod 17, causing the third connecting rod 15 to rotate within the rotating groove 14. This causes the third connecting rod 15 to rotate the two second bevel gears 13 within the two gear grooves 11. The two second bevel gears 13 then drive the two first bevel gears 12 within the two gear grooves 11, which in turn drive the two screws 23 within the two first sliding grooves 3. This allows the two first connecting rods 4 to move along the two first sliding grooves 3 under the influence of the threads of the two screws 23, ensuring that the user can control the simultaneous movement of the two first connecting rods 4.

[0032] Example 3: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features and includes: Several fixing blocks 18 are fixedly connected to the top surface of the first support rod 1. Each fixing block 18 is rotatably connected to a pressing block 19, and the pressing block 19 is in contact with the rotating rod 17. The extrusion assembly is located on the rotating rod 17 and is used to extrude several extrusion blocks 19.

[0033] In use, the user squeezes several squeezing blocks 19 through the squeezing component, causing the squeezing blocks 19 to rotate inward, thereby clamping and fixing the rotating rod 17 and ensuring that the rotating rod 17 rotates under external influence, thus improving the stability of the overall device.

[0034] Example 4: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features: the extrusion component includes: The threaded groove 20 is formed on the periphery of the rotating rod 17. A threaded sleeve 21 is threadedly connected to the threaded groove 20. A pressing groove 22 is formed on the bottom surface of the threaded sleeve 21.

[0035] In use, the user rotates the threaded sleeve 21 by hand, causing the threaded sleeve 21 to move downward under the action of the threaded groove 20. This causes the threaded sleeve 21 to drive the inner wall of the extrusion groove 22 to extrude several extrusion blocks 19, ensuring that several extrusion blocks 19 can be extruded simultaneously.

[0036] Example 5: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features: the tops of several extrusion blocks 19 are all inclined, and the tops of several extrusion blocks 19 are inserted into the extrusion groove 22.

[0037] Since the tops of several extrusion blocks 19 are all inclined, when the inner wall of the extrusion groove 22 presses the tops of several extrusion blocks 19, several extrusion blocks 19 can rotate in the direction of the rotating rod 17, and ensure that when the threaded sleeve 21 drives the extrusion groove 22 to move downward to a suitable position, the tops of several extrusion blocks 19 can be inserted into the extrusion groove 22.

[0038] Example 6: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on the two screws 23 have the same direction of rotation and the same thread pitch. The screws 23 are located in the first slide groove 3 and are rotatably connected to the first slide groove 3.

[0039] Since the threads on the two screws 23 have the same direction of rotation and the same thread pitch, when the two screws 23 rotate, the two first connecting rods 4 will be acted upon by the threads of the two screws 23 and move simultaneously along the two first sliding grooves 3, ensuring that the screws 23 can rotate normally within the first sliding grooves 3 when they rotate.

[0040] Example 7: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the first bevel gear 12 is rotatably connected to the first slide groove 3, and both ends of the third connecting rod 15 are rotatably connected to the two gear grooves 11 respectively.

[0041] Specifically, it is ensured that when the first bevel gear 12 rotates, one end of the first bevel gear 12 can rotate normally in the first slide groove 3, and it is also ensured that when the third connecting rod 15 rotates, both ends of the third connecting rod 15 can rotate normally in the two gear grooves 11 respectively.

[0042] Example 8: This example provides a photovoltaic equipment maintenance electric shock safety device. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the rotating rod 17 is rotatably connected to one of the gear slots 11, and anti-slip texture is provided on the periphery of the rotating rod 17.

[0043] Specifically, it is ensured that when the rotating rod 17 rotates, one end of the rotating rod 17 can rotate normally within one of the gear slots 11. Furthermore, because the rotating rod 17 is provided with anti-slip texture on its periphery, when the rotating rod 17 is rotated by hand, the anti-slip texture will increase the friction between the hand and the rotating rod 17, reducing the occurrence of hand slippage.

[0044] Working principle: In use, the user manually rotates the rotating rod 17, causing the third connecting rod 15 to rotate within the rotating groove 14. This causes the third connecting rod 15 to rotate the two second bevel gears 13 within the two gear grooves 11. The two second bevel gears 13 then drive the two first bevel gears 12 within the two gear grooves 11, which in turn drive the two screws 23 within the two first sliding grooves 3. This causes the two first connecting rods 4 to move along the two first sliding grooves 3 under the action of the screws 23. The two first connecting rods 4 then drive the second support rods 10 to move via the two first fixed rods 5, moving the second support rods 10 away from the first support rods 1. As the second support rods 10 move, they pull the second connecting rods 8 along the second sliding grooves 7 via the second fixed rods 9, ensuring that the user can adjust the length of the entire device to flexibly adapt to installation requirements. When in use, the user rotates the threaded sleeve 21 by hand, causing the threaded sleeve 21 to move downward under the action of the threaded groove 20. This causes the threaded sleeve 21 to drive the inner wall of the extrusion groove 22 to extrude several extrusion blocks 19, which in turn rotate inward and clamp and fix the rotating rod 17, ensuring that the rotating rod 17 rotates under external influences, thereby improving the stability of the overall device.
