[0010] Preferably, the fence gate includes two equally divided split door panels. The upper end of the split door panels is provided with pulleys, and the fence frame is provided with pulley tracks. The split door panels have an open state where they overlap the inner side of the fence side panels and a closed state where they are combined to form the fence gate. The pulleys slide along the pulley tracks to change the state of the split door panels. In the closed state, the splicing sides of the two split door panels are locked together by a locking structure.

[0011] Preferably, the locking structure includes a first fixing member, a second fixing member, a pin movably installed on the first fixing member, and a pin hole provided in the second fixing member, wherein the pin and the pin hole cooperate.

The mounting crossbeam is fixed to the pole by a clamp.

[0015] Preferably, the fence frame is a rectangular frame structure; and / or, the fence side panels and the fence frame are an integral structure.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. This utility model provides a suspended protective fence device for a pole-mounted transformer, including a suspension component located above the pole-mounted transformer and a rectangular fence assembly surrounding the circumference of the transformer. The suspension component is located above the transformer and fixed to the pole, while the fence frame is connected to the suspension component. Because it is suspended, there is no need to pour a concrete foundation on the ground for fixing, thus saving ground space. Furthermore, the fence assembly includes a top fence frame, a bottom openable fence base plate, front and rear fence side plates, and left and right fence gates. Before hoisting the fence assembly, the suspension component is connected to the pole. Then, with the fence base plate and fence gates open, the fence assembly can be hoisted from top to bottom and surrounds the circumference of the transformer. Finally, the fence frame is connected to the suspension component, and the fence base plate and fence gates are closed, facilitating the suspension installation of the fence assembly.

[0018] 2. The fence base plate comprises two equally divided separate panels. The outer sides of the separate panels are connected to the fence side panels via hinges. The splicing sides of the two separate panels are locked together by a locking structure. The separate panels have an open state where they overlap the outer sides of the fence side panels. The fence side panels are provided with a limiting structure that connects to the separate panels in the open state. Thus, the separate panels of the fence base plate are connected to the fence side panels via hinges, allowing the separate panels to open and close smoothly around the hinges. In the closed state, the locking structure fixes the two separate panels into a single fence base plate, preventing it from being opened arbitrarily and providing protection and safety. In the open state, the separate panels rotate outwards, overlapping the outer sides of the fence side panels, and the limiting structure keeps the two separate panels in the open state.

[0019] 3. The fence gate comprises two equally divided split gate panels. Each split gate panel has a pulley at its upper end, and the fence frame has a pulley track. The split gate panels have an open state where they overlap the inner side panels of the fence, and a closed state where they are combined to form the fence gate. The pulleys slide along the pulley track to change the state of the split gate panels. In the closed state, the splicing sides of the two split gate panels are locked together by a locking structure. This allows for easy hoisting and disassembly of the fence components when the split gate panels are open. After hoisting, the fence is switched to the closed state, with the entire fence assembly surrounding the transformer on the column, providing protection for the transformer. Because the split gate panels are changed by sliding the pulleys along the pulley track, the operation is relatively labor-saving and convenient.

[0020] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0039] like Figures 1 to 11 As shown, this utility model provides a suspended protective fence device for a pole-mounted transformer. The pole-mounted transformer 2 is installed on a pole 1. Typically, two poles 1 are arranged side-by-side, vertically installed on the ground, forming the physical framework of the power grid. To install the pole-mounted transformer 2, a lower crossarm 5 is fixed to the pole 1. The lower crossarm 5 is secured to the pole using clamps 6. The pole-mounted transformer 2 is installed above the lower crossarm 5, and a JP cabinet 7 is installed below the lower crossarm 5. Both the pole-mounted transformer 2 and the JP cabinet 7 are existing technologies, and their installation structures are also existing technologies. The JP cabinet 7 is the low-voltage switchgear for the pole-mounted transformer 2, integrating functions such as power distribution, metering, protection, and reactive power compensation. The pole-mounted transformer 2 is a static power device that uses the principle of electromagnetic induction to change the AC voltage level, achieving voltage increase (boost) or decrease (step down) through magnetic field coupling.

[0040] In existing technologies, pole-mounted transformers 2 are equipped with fences, but using traditional ground-mounted fences requires a concrete foundation for fixed installation, which occupies ground space. To avoid occupying ground space, this embodiment proposes a practical and feasible solution based on the aforementioned business pain points and related village development technologies, to assist in the construction of power stations in village development projects and promote the further development of the photovoltaic industry. Specifically, a suspended protective fence device is adopted. The suspended protective fence device includes a suspension component located above the pole-mounted transformer 2 and a rectangular fence assembly 3 surrounding the circumference of the pole-mounted transformer. The fence assembly 3 includes a top fence frame 31, a bottom fence base plate 33, fence side plates 32 located on the front and rear sides, and fence gates 34 located on the left and right sides. The suspension component is fixed to the pole 1, and the fence frame 31 is connected to the suspension component, thereby allowing the fence assembly to be suspended without the need for a concrete foundation for fixed installation, thus saving ground space. Before hoisting the fence components, the suspension components are connected to the pole. Then, with the fence base plate and fence gate open, the fence components can be hoisted from top to bottom and enclosed around the transformer on the pole. Finally, the fence frame is connected to the suspension components, and the fence base plate and fence gate are closed, which facilitates the suspension and installation of the fence components.

[0041] Typically, the fence frame 31 is designed as a rectangular frame structure. In addition, the fence base plate 33, fence side plates 32, and fence gate 34 are also rectangular structures, thus forming a rectangular fence assembly 3, which can provide all-round, standardized safety protection for the pole-mounted transformer and improve safety.

[0042] In this embodiment, the suspension component is the upper crossarm 4, which is fixed to the pole 1 using clamps 6. The upper crossarm is a horizontal support component, longer than a regular crossarm, used to suspend the fence assembly and serving as the support and fixing point for the entire fence device. The left and right sides of the fence frame 31 are placed on the upper crossarm and fixed to it with bolts. Thus, with the fence base plate and gate open, after the fence assembly is hoisted into place from top to bottom, the left and right sides of the fence frame are supported by the upper crossarm, and finally fixed with bolts, ensuring the stability of the suspended installation structure of the fence assembly and convenient installation. Furthermore, there is an installation gap between the left and right sides of the fence frame 31 and the upper end of the fence gate to allow the upper crossarm 4 to pass through.

[0043] In some embodiments, the fence base plate 33 includes two equally divided split plates 331. The outer sides of the split plates are connected to the fence side plates 32 via hinges 35, and the splicing sides of the two split plates are locked together by a locking structure 36. The fence base plate 33 has a through hole 332 for a power supply rod to pass through, and the splicing sides of the split plates have a half-hole, which is combined to form the through hole 332. The split plates of the fence base plate are connected to the fence side plates via hinges, allowing the split plates to open and close smoothly around the hinges. In the closed state, the locking structure fixes the two split plates into a single fence base plate, preventing it from being opened arbitrarily and providing protection and safety. In the open state, the split plates rotate outwards, overlapping the outer side of the fence side plates, and a limiting structure keeps the two split plates in the open state.

[0044] like Figure 8 , Figure 10 and Figure 11 As shown, furthermore, to maintain the open state, the fence side panel 32 is provided with a limiting structure 37 that connects to the split panel in the open state. The limiting structure 37 includes a flip plate 371 hinged to the side of the fence side panel, the flip plate having a limiting groove 373, and the side of the split panel having a limiting pin 372, the limiting groove 373 engaging with the limiting pin 372. To release the limiting position, the flip plate is flipped upwards, separating the limiting groove from the limiting pin.

[0045] In some embodiments, the fence gate 34 includes two separate gate panels 341. Each separate gate panel has a pulley at its upper end, and the fence frame 31 has a pulley track. The separate gate panels 341 have an open state where they overlap the inner side of the fence side panels, and a closed state where they are combined to form the fence gate. The pulleys slide along the pulley track to change the state of the separate gate panels. In the closed state, the splicing sides of the two separate gate panels are locked together by a locking structure. Thus, in the open state, the separate gate panels facilitate the hoisting and disassembly of the fence components. After hoisting, the panels are switched to the closed state, and the entire fence component surrounds the transformer on the column, providing protection for the transformer. Because the state of the separate gate panels is changed by the pulleys sliding along the pulley track, the operation is less strenuous and convenient.

[0046] Understandably, to facilitate the sliding of the split door panels from the left or right side to the front or back side, the pulley track is equipped with an arc transition section. That is, the pulley track is equipped with an arc transition section at the corner of the fence frame. In addition, the pulley includes a pulley body and a pulley seat. The pulley body is installed on the pulley seat, and the pulley seat is equipped with a horizontal rotation joint, so that the split door panels can rotate horizontally while moving along the pulley track, so that the split door panels can slide from the left or right side to the front or back side, and from the front or back side to the left or right side.

[0047] like Figure 7 and Figure 9 As shown, in some embodiments, the locking structure 36 includes a first fixing member 361, a second fixing member 362, a pin 363 movably mounted on the first fixing member, and a pin hole 365 provided in the second fixing member, wherein the pin engages with the pin hole. The first fixing member 361 has a groove 364 for the pin to slide horizontally, the pin has a handle 366, and the head end of the pin has a locking hole 367. The locking hole can connect to a locking ring, thereby achieving locking of the locking structure.

[0048] like Figure 6 As shown, the fence base plate 33 is provided with a fixing plate 333 that cooperates with the split door panel. The two fixing plates 333 are arranged side by side, forming a fixing groove between them, which fixes the lower end of the split door panel in the closed state.

[0049] It is understood that the fence side panels and the fence frame are an integral structure, or they can be assembled into one piece from separate parts.

[0050] The aforementioned fence frame 31, fence base plate 33, fence side plate 32, and fence gate 34 can be made of stainless steel. The fence side plate 32 and fence gate 34 are equipped with grilles. The materials and structures are mature and widely used in the market, and have the advantages of high reliability, convenient installation and use, and high safety.

[0051] Before hoisting the fence assembly, open all locking mechanisms, flip the two separate panels of the fence base plate outwards 270 degrees so that they overlap the outside of the fence side panels, and use the limiting mechanism to fix the fence base plate to the fence side panels. Push the separate gate panels; the pulleys slide along the pulley track, causing the two separate gate panels of the fence gate to open to the inside of the fence side panels on both sides. This completes the fence assembly's transition from closed to open. After opening, the fence assembly can be hoisted. Once in place, close the fence assembly and lock all locking mechanisms.

[0052] It is understood that the pole-mounted transformer suspended protective fence device in this embodiment can be applied to scenarios where photovoltaic power generation projects cannot install traditional ground fences for various reasons. In photovoltaic power stations with such needs, this product can be reasonably assembled to complete the installation of the suspended protective fence device.

[0053] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
