During the operation of photovoltaic power generation equipment, the transmission and distribution connection device, as a key component for power transmission, directly affects the stability and safety of the power generation system. Existing photovoltaic power generation equipment transmission and distribution connection devices have many problems in practical use. On the one hand, traditional connection devices have relatively simple fixing methods for cables of different specifications, making it difficult to achieve fast, accurate, and stable connections. Over long-term use, loosening and poor contact are prone to occur, leading to decreased power transmission efficiency and even safety hazards. On the other hand, existing connection devices lack effective protective measures. In complex outdoor environments, they are susceptible to factors such as wind, rain, dust, and corrosion, accelerating device aging, reducing their service life, and increasing equipment maintenance costs and failure risks. Furthermore, existing devices also have insufficient installation adaptability, failing to meet the needs of diverse installation scenarios and limiting their widespread application. Therefore, the development of a photovoltaic power generation equipment transmission and distribution connection device with efficient fixing, reliable protection, and good installation adaptability is urgently needed.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This photovoltaic power generation equipment transmission and distribution connection device includes an installation and fixing unit. The device passes through the inner side of the connecting base and the pressure block. Based on a pre-determined diameter of the wire, a knob is rotated, causing a threaded rod to engage with a meshing gear ring. This causes the threaded rod to push the pressure block downwards. Adjustments can be made for wires of different diameters. Furthermore, activating an electric telescopic rod pushes a connecting plate, which in turn moves a locking plate, causing the connecting block and pressure block to move downwards, thus fixing the wire. This allows for quick and convenient fixing of wires of different specifications to the connection body.

[0013] This photovoltaic power generation equipment transmission and distribution connection device, by installing a protective unit, then flipping the protective cover around the flipping shaft, and further pulling the pull plate, causes the pull plate to drive the locking rod, which in turn causes the fixing plate to compress the spring, and further places the locking plate on the side of the lock box. Releasing the pull plate, under the action of the spring, causes the locking rod to return to its original position, thereby fixing the protective cover and further achieving the effect of protecting the equipment above the connection base.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a photovoltaic power generation equipment transmission and distribution connection device, including a connection base 1 and a mounting plate 2. The mounting plate 2 is installed on the upper and lower sides of the connection base 1. A connection mechanism is provided on the outer surface of the connection base 1. The connection mechanism includes a fixing unit and a protective unit. The fixing unit is installed on the inner side of the connection base 1, and the protective unit is installed on the outer surface of the connection base 1.

[0021] The fixing unit includes a bracket 11, which is fixedly connected to the top of the connecting base 1. An electric telescopic rod 12 is movably connected to the inner side of the bracket 11. A connecting plate 13 is connected to the output end of the electric telescopic rod 12. A locking plate 14 is connected to the inner side of the connecting plate 13. A connecting block 15 is fixedly connected to the side of the locking plate 14. A meshing gear ring 16 is provided at the other end of the connecting block 15. A threaded rod 17 is movably connected inside the meshing gear ring 16. A knob 18 is fixedly connected to the side of the threaded rod 17. A pressure block 19 is connected to the other end of the threaded rod 17. Thus, by installing the fixing unit, the rod passes through the connecting base 1 and the pressure block 19... Inside block 19, the diameter of the wire is determined in advance. By rotating knob 18, the knob 18 drives threaded rod 17 to engage with meshing gear ring 16, thereby causing threaded rod 17 to push pressure block 19 downward. It can be further adjusted according to wires of different diameters. By activating electric telescopic rod 12, electric telescopic rod 12 pushes connecting plate 13, thereby causing connecting plate 13 to drive locking plate 14, which in turn causes connecting block 15 to drive pressure block 19 downward, thereby fixing the wire. It can quickly and conveniently fix wires of different specifications to the connecting body.

[0022] The contact surface of the pressure block 19 is an arc-shaped surface. A protective layer is installed on the arc-shaped surface at the bottom of the pressure block 19. The bottom of the protective layer has anti-slip texture. By installing the protective layer, the damage to the wire during wire fixing is further reduced.

[0023] The protective unit includes a flip shaft 3, which is installed on both sides of the connecting base 1. A protective cover 4 is movably connected to the outer surface of the flip shaft 3. A locking plate 5 is fixedly connected to the bottom of the protective cover 4. A locking box 6 is provided on the side of the connecting base 1. A locking rod 7 is movably connected inside the locking box 6. A fixing plate 9 is provided on the outer surface of the locking rod 7 and inside the locking box 6. A spring 10 is provided on the outer surface of the fixing plate 9. A pull plate 8 is fixedly connected to the end of the locking rod 7. By installing the protective unit, the protective cover 4 is flipped around the flip shaft 3. By pulling the pull plate 8, the pull plate 8 drives the locking rod 7, which in turn causes the fixing plate 9 to compress the spring 10. The locking plate 5 is then placed on the side of the locking box 6. When the pull plate 8 is released, the locking rod 7 returns to its original position under the action of the spring 10, thus fixing the protective cover 4 and further protecting the equipment above the connecting base 1.

[0024] The inner surface of the protective cover 4 is provided with an insulating and shock-absorbing layer. The insulating and shock-absorbing layer is made of a composite material of rubber and insulating fiber, which can effectively isolate external conductive substances and buffer external impacts, providing double protection for the equipment connected to the base 1.

[0025] The outer surface of the knob 18 is provided with anti-slip texture, and the knob 18 is marked with a rotation direction indicator arrow. The anti-slip texture makes it easy for the operator to apply force, and the indicator arrow clearly indicates the rotation direction, improving the convenience and accuracy of the knob 18 adjustment operation.

[0026] The mounting plate 2 has multiple mounting holes of different sizes. The distribution of the mounting holes is adapted to various common installation and fixing methods, which can meet the needs of different installation scenarios and enhance the versatility and flexibility of the connection device installation.

[0027] Working principle: When this connecting device is working, in terms of fixing the wire, the bracket 11 in the fixing unit is fixed to the top of the connecting base 1. The electric telescopic rod 12, connecting plate 13, locking plate 14, connecting block 15, meshing toothed ring 16, threaded rod 17, knob 18 and pressure block 19 work together. First, according to the wire diameter, by rotating the knob 18 with anti-slip embossing and directional arrow, the threaded rod 17 engages with the meshing toothed ring 16 to push the pressure block 19 to move and adjust. Then, the electric telescopic rod 12 is activated to drive the pressure block 19 to move down, thereby fixing wires of different specifications. The pressure block 19 is arc-shaped. The protective layer and anti-slip texture on the surface can reduce damage to the wires; in terms of equipment protection, the protective unit allows the protective cover 4 to rotate around the connecting base 1 via the flip shaft 3. Pulling the pull plate 8 drives the locking rod 7 to compress the spring 10 by the fixing plate 9. After the locking plate 5 is placed into the side of the lock box 6, the pull plate 8 is released, and the spring 10 causes the locking rod 7 to return and fix the protective cover 4. Its internal insulating and shock-absorbing layer can isolate conductive materials and buffer impacts, thus protecting the equipment above the connecting base 1. In addition, the mounting plate 2 has multiple sizes of mounting holes to adapt to common installation methods, enhancing the universality and flexibility of the connection device installation.
