[0040] As shown in the background technology, in the prior art, the foundation of the box-type transformer includes a platform, an oil pool and prefabricated pipe piles. Some of the prefabricated pipe piles extend out of the ground, and the tops of the prefabricated pipe piles are connected to the platform. The box-type transformer is set on the platform, and the oil pool is used to connect with the box-type transformer to store the oil leaked from the box-type transformer.

[0041] However, the box-type transformer has a certain height, and it is difficult to connect the box-type transformer with the oil pool, which is inconvenient to operate.

[0042] Based on this, the fan box transformer foundation provided in the embodiment of the present application is provided with a support platform, an oil collecting box, a plurality of support columns and at least one bracket. The support platform is provided above the support column. The support platform is used to place the box-type transformer. The support platform has a plurality of flow holes, and the flow holes are connected to the box-type transformer. The bracket includes a support member and two telescopic members provided on the support member, and the telescopic members are connected to the bottom of the support platform. The oil collecting box is provided on the support member, and some of the telescopic members move relative to the support platform to adjust the height of the oil collecting box on the support member so that the oil collecting box is connected to the flow holes, thereby connecting the oil collecting box to the box-type transformer, and the oil leaked from the box-type transformer flows into the oil collecting box through the flow holes, and the oil collecting box stores it. The fan box transformer foundation provided in the embodiment of the present application has a simple connection method between the oil collecting box and the box-type transformer, and is easy to operate.

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of them. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the embodiments of the present application, and cannot be understood as limitations on the embodiments of the present application. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the embodiments of the present application.

[0044] Reference Figure 1 , Figure 2 and Figure 7 As shown, the wind turbine box transformer foundation provided in the embodiment of the present application includes: a plurality of support columns 100; a support platform 200, which is arranged above the support columns 100, and the support platform 200 is used to place the box transformer 10, and the support platform 200 has a flow hole 210.

[0045] At least one bracket 300 includes a support member 310 and two telescopic members 320 disposed on the support member 310 , and the telescopic members 320 are connected to the bottom of the support platform 200 .

[0046] The oil collecting tank 400 is arranged on the supporting member 310 . The flow hole 210 is used to connect the oil collecting tank 400 with the box-type transformer 10 . The partial telescopic member 320 moves relative to the supporting platform 200 to adjust the height of the oil collecting tank 400 .

[0047] There are multiple support columns 100 , and the number of the support columns 100 may be four or six, or more, and the embodiment of the present application does not impose too many restrictions on this.

[0048] It can be understood that the support platform 200 provides a stable installation foundation for the box-type transformer 10, ensuring the safe placement and operation of the box-type transformer 10. The support platform 200 is arranged above the support column 100, and the support platform 200 evenly distributes the weight to each support column 100, reducing the load pressure of a single support column 100. The support column 100 lifts the support platform 200 to a certain height, which can prevent the box-type transformer 10 from being affected by ground moisture or water, thereby preventing the electronic components inside the box-type transformer 10 from getting damp. The box-type transformer 10 maintains a certain distance from the ground surface, so that people around cannot easily touch the box-type transformer 10, reducing the possibility of electric shock and improving safety.

[0049] It should be noted that in some installation sites with uneven terrain, the length of each support column 100 can be selected as needed to ensure the stability of the support platform 200. For example, the support column 100 can be a prefabricated pipe pile, and the support platform 200 can be a steel plate, which is convenient for construction, has a short construction period, and is fast to build. The support platform 200 can be treated by shot blasting to avoid corrosion and rust. The height of the support platform 200 from the ground can be 2 to 3 meters. From the ground to the support platform 200, an up and down escalator can be set, and a safety guardrail can be installed on the edge of the escalator and the support platform 200.

[0050] The flow hole 210 is used to connect the oil collecting box 400 and the box-type transformer 10. The flow hole 210 provides a flow passage, which can guide the oil leaked from the box-type transformer 10 to flow into the oil collecting box 400 below to prevent the oil from spreading to the surrounding environment and reduce pollution. Exemplarily, the flow hole 210 can be circular or rectangular, or other shapes, and the embodiments of the present application do not impose too many restrictions on this.

[0051] It should also be noted that the bottom of the oil collecting tank 400 may have a 2% inclination, and an oil-water separation device may be provided at the bottom of the oil collecting tank 400 to discharge water and store oil.

[0052] At least one bracket 300, the number of the bracket 300 can be one; the number of the bracket 300 can also be two or more than two, the brackets 300 are arranged in parallel, the support members 310 on each bracket 300 are located at the same height, and the support members 310 jointly support the oil collecting tank 400 to keep the oil collecting tank 400 balanced.

[0053] The bracket 300 includes a support member 310 and a telescopic member 320. The support member 310 is provided to provide a placement position for the oil collecting box 400 and to provide support for the oil collecting box 400, thereby ensuring that it remains stable during use. Two telescopic members 320 are provided on the support member 310, and the two telescopic members 320 can be connected to the two ends of the support member 310 respectively. When part of the telescopic member 320 moves toward the support platform 200, the height of the support member 310 can be increased, thereby increasing the height of the oil collecting box 400 on the support member 310, so that the oil collecting box 400 is connected to the flow hole 210, which is convenient for operation. When part of the telescopic member 320 moves away from the support platform 200, the height of the support member 310 can be lowered, thereby lowering the height of the oil collecting box 400 on the support member 310, so as to facilitate the disassembly or replacement of the oil collecting box 400.

[0054] It should also be noted that when the height of the oil collecting tank 400 is adjusted to abut against the bottom of the supporting platform 200, the oil leaked from the box-type transformer 10 can directly flow into the oil collecting tank 400 below through the flow hole 210, which reduces the flow path of the oil and improves the collection speed of the oil. At the same time, it can prevent the oil from splashing out of the oil collecting tank 400, thereby improving the reliability of the oil collecting tank 400.

[0055] It can be understood that, compared with the difficulty in connecting the transformer and the oil pool in the prior art, the fan box transformer foundation provided by the embodiment of the present application is provided with a support platform 200, an oil collecting box 400, a plurality of support columns 100 and at least one bracket 300, the support platform 200 is arranged above the support column 100, the support platform 200 is used to place the box-type transformer 10, and the support platform 200 has a plurality of flow holes 210, and the flow holes 210 are connected with the box-type transformer 10. The bracket 300 includes a support member 310 and two telescopic members 320 arranged on the support member 310, and the telescopic member 320 is connected to the bottom of the support platform 200. The oil collecting box 400 is arranged on the support member 310, and the partial telescopic member 320 moves relative to the support platform 200 to adjust the height of the oil collecting box 400 on the support member 310, so that the oil collecting box 400 is connected with the flow hole 210, so that the oil collecting box 400 is connected with the box-type transformer 10, and the oil leaked from the box-type transformer 10 flows into the oil collecting box 400 through the flow hole 210, and the oil collecting box 400 stores the oil. The fan box transformer provided in the embodiment of the present application has a simple connection method between the oil collecting box 400 and the box-type transformer 10, and is easy to operate.

[0056] In some embodiments, reference Figure 3 As shown, the telescopic member 320 is provided with a plurality of telescopic parts 321 which are nested and connected in sequence, and the telescopic part 321 located at the top is connected to the bottom of the supporting platform 200 .

[0057] It can be understood that the nested telescopic parts 321 make the height adjustment simple and intuitive. The operator can quickly adjust the oil collecting tank 400 to the required height by stretching or compressing each telescopic part 321, which is easy to operate and improves work efficiency.

[0058] In a specific implementation, a motor 230 may be installed on the supporting platform 200 . The motor 230 is electrically connected to the telescopic portion 321 , and the extension or compression of the telescopic portion 321 is controlled by the motor 230 .

[0059] In some embodiments, reference Figure 3 As shown, the telescopic member 320 also has a connecting portion 322 , and the telescopic member 320 is connected to the bottom of the supporting platform 200 via the connecting portion 322 .

[0060] Specifically, the connecting portion 322 provides a connection position for the telescopic member 320, ensuring that the telescopic member 320 is firmly connected to the supporting platform 200, thereby improving the stability of the entire structure and preventing the oil collecting tank 400 from shaking or shifting during use.

[0061] It should be noted that a connection hole may be provided on the connection portion 322 , and the connection portion 322 may be connected to the bottom of the support platform 200 through the connection hole by bolts.

[0062] In some embodiments, reference Figure 1 and Figure 4 As shown, the wind turbine box transformer foundation also includes at least one sliding member 500, the sliding member 500 includes an upper slide rail 510 and a lower slide rail 520 slidably connected to the upper slide rail 510, the lower slide rail 520 is connected to the support member 310, and the oil collecting tank 400 is arranged on the upper slide rail 510.

[0063] At least one sliding member 500, the number of sliding members 500 can be one; the number of sliding members 500 can also be two, the two sliding members 500 are arranged in parallel on the support member 310, and the two sliding members 500 jointly support the oil collecting tank 400; the number of sliding members 500 can also be more than two, and the embodiment of the present application does not impose too many restrictions on this.

[0064] Specifically, the sliding member 500 includes an upper slide rail 510 and a lower slide rail 520, the upper slide rail 510 is slidably connected to the lower slide rail 520, the upper slide rail 510 can slide relative to the lower slide rail 520, and the oil collecting box 400 is arranged on the upper slide rail 510, so that the upper slide rail 510 can drive the oil collecting box 400 to move, so as to adjust the position of the oil collecting box 400 on the horizontal plane, so as to achieve the connection between the oil collecting box 400 and the flow hole 210. It should be noted that when replacing or maintaining the oil collecting box 400, the position of the oil collecting box 400 on the horizontal plane is changed to move the oil collecting box 400 to a position that is easy to access, so as to facilitate the replacement of the oil collecting box 400.

[0065] It should also be noted that the lower sliding rail 520 and the support member 310 can be connected by bolts or other methods, and the embodiment of the present application does not impose too many restrictions on this.

[0066] In some embodiments, reference Figure 1 , Figure 4 and Figure 5 As shown, one of the upper slide rail 510 and the oil collecting box 400 is provided with a slide groove 511 , and the other is provided with a pulley 410 matching the slide groove 511 , and the pulley 410 is in contact with the slide groove 511 .

[0067] It is understandable that by providing the pulley 410 and the slide groove 511, the oil collecting box 400 can move smoothly relative to the upper slide rail 510. When the pulley 410 rolls in the slide groove 511, the friction resistance is reduced, making the movement smoother and more labor-saving. Exemplarily, the pulley 410 can be a universal wheel.

[0068] It should be noted that a slide groove 511 can be provided on the upper slide rail 510 and a pulley 410 can be provided on the oil collecting box 400; or a pulley 410 can be provided on the upper slide rail 510 and a slide groove 511 can be provided on the oil collecting box 400. The embodiment of the present application does not impose too many restrictions on this.

[0069] In some embodiments, reference Figure 4 As shown, a limiting portion 512 is provided at the end of the slide groove 511 , and the limiting portion 512 is used to limit the pulley 410 in the slide groove 511 .

[0070] Specifically, the movement range of the pulley 410 can be limited by setting the limiting portion 512, so as to prevent the pulley 410 from accidentally sliding out of the chute 511, and avoid the oil collecting box 400 from accidentally falling during the sliding process, thereby improving safety. Exemplarily, the shape of the limiting portion 512 can be a cube, a cuboid, a cylinder or a sphere, or other shapes, mainly to limit the pulley 410 in the chute 511, and the embodiment of the present application does not impose too many restrictions on this.

[0071] It should be noted that a limiting portion 512 may also be provided on the lower slide rail 520 to limit the sliding distance of the upper slide rail 510 to prevent the upper slide rail 510 from being separated from the lower slide rail 520 .

[0072] In some embodiments, reference Figure 6 As shown, a control valve 420 and an oil drain pipeline 430 are provided on the oil collecting tank 400 , and the control valve 420 connects the oil drain pipeline 430 with the oil collecting tank 400 .

[0073] Specifically, the setting of the control valve 420 allows the operator to easily control the discharge process of the oil, without the need for complex equipment or operating steps, and is easy to operate. The setting of the control valve 420 and the oil discharge pipeline 430 at the same time can effectively manage and control the flow of the oil in the oil collecting tank 400, and can timely discharge excess oil when the oil collecting tank 400 reaches a certain capacity, thereby preventing oil from overflowing, reducing environmental pollution, and improving the safety of the oil collecting tank 400.

[0074] It should be noted that the control valve 420 can be an electric valve or a manual valve, and the embodiment of the present application does not impose too many restrictions on this.

[0075] In some embodiments, reference Figure 6 As shown, the oil collecting tank 400 is also provided with a liquid level meter 440 and a controller, and the liquid level meter 440 is used to detect the oil storage depth in the oil collecting tank 400 .

[0076] The liquid level meter 440 and the control valve 420 are both electrically connected to the controller. When the oil storage depth is greater than or equal to a preset depth, the controller controls the control valve 420 to open.

[0077] It should be noted that the system can realize automatic management by real-time detection of the oil depth in the oil collecting tank 400 by the liquid level meter 440 and transmission of the data to the controller. When the oil depth reaches or exceeds the preset depth, the controller automatically opens the control valve 420 to discharge the oil, which reduces the dependence on manual monitoring and operation, improves the automation of the system, and reduces labor costs.

[0078] The automatic control system can respond promptly to changes in oil storage depth, prevent oil spills, reduce environmental pollution, and thus maintain site cleanliness and safety.

[0079] It should also be noted that the controller can integrate an alarm function, which will sound an alarm when the liquid level approaches a preset depth to alert the operator, thereby further improving the reliability of the oil collecting tank 400.

[0080] In some embodiments, reference Figure 6 As shown, a viewing port 450 is provided on the side wall of the oil collecting tank 400 .

[0081] It is understandable that the observation port 450 can be set to directly observe the oil volume and oil color in the oil collecting tank 400, thereby realizing real-time monitoring of the oil state, quickly understanding the state of the oil, and promptly discovering abnormal conditions (such as excessive oil volume or oil deterioration). In specific implementation, a mounting hole can be opened on the side wall of the oil collecting tank 400 for mounting transparent tempered glass, and a high-strength adhesive such as polyurethane glue can be used to bond the transparent tempered glass to the side wall of the oil collecting tank 400, thereby realizing the setting of the observation port 450.

[0082] The operator can check the oil status through the observation port 450 without opening the oil collecting tank 400, thereby simplifying the daily maintenance and inspection procedures, reducing the dependence on tools and equipment, and improving work efficiency.

[0083] In some embodiments, reference Figure 2 and Figure 7 As shown, a heat dissipation portion 220 is provided on the support platform 200 , and the flow hole 210 is located on the heat dissipation portion 220 . The heat dissipation portion 220 is used to place the box-type transformer 10 .

[0084] It should be noted that the heat dissipation part 220 can improve the heat dissipation capacity of the box-type transformer 10. The heat dissipation part 220 can quickly dissipate the heat generated during the operation of the transformer to prevent overheating and maintain the box-type transformer 10 in an optimal temperature range, thereby improving its operating efficiency and performance.

[0085] The flow hole 210 is located on the heat dissipation part 220 . The box-type transformer 10 placed on the heat dissipation part 220 can be connected with the oil collecting tank 400 through the flow hole 210 , so that the oil leaked from the box-type transformer 10 enters the oil collecting tank 400 through the flow hole 210 .

[0086] In a specific implementation, the heat dissipation part 220 can be paved with a steel mesh, which has good heat dissipation performance and reduces the possibility of high temperature tripping of the box-type transformer 10.

[0087] It can be understood by those skilled in the art that the fan box transformer foundation provided in the embodiment of the present application is provided by providing a support platform 200, an oil collecting box 400, a plurality of support columns 100 and at least one bracket 300, the support platform 200 is provided above the support column 100, the support platform 200 is used to place the box transformer 10, and the support platform 200 has a plurality of flow holes 210, and the flow holes 210 are connected to the box transformer 10. The bracket 300 includes a support member 310 and two telescopic members 320 provided on the support member 310, and the telescopic member 320 is connected to the bottom of the support platform 200. The oil collecting box 400 is arranged on the support member 310, and the partial telescopic member 320 moves relative to the support platform 200 to adjust the height of the oil collecting box 400 on the support member 310, so that the oil collecting box 400 is connected with the flow hole 210, so that the oil collecting box 400 is connected with the box-type transformer 10, and the oil leaked from the box-type transformer 10 flows into the oil collecting box 400 through the flow hole 210, and the oil collecting box 400 stores the oil. The fan box transformer provided in the embodiment of the present application has a simple connection method between the oil collecting box 400 and the box-type transformer 10, and is easy to operate.
