Description

Technical Field

[0001] This utility model relates to the field of transformer substation operation and maintenance technology, specifically to an auxiliary tooling for the operation and maintenance of wind power transformer substations. Background Technology

[0002] Wind power transformer substations are the core hubs for power transmission in wind farms, responsible for stepping up the low-voltage electricity generated by wind turbines to the grid's appropriate voltage. Their operation and maintenance quality directly determines the continuity and safety of power generation in wind farms. Unlike conventional distribution substations, wind power transformer substations are mostly located at the bottom of wind turbines or at the edge of wind farms, exposed to harsh environments such as high altitudes, strong winds, low temperatures, and dust storms. This results in rapid component aging and numerous potential causes of failure, demanding high efficiency and safety in operation and maintenance.

[0003] Existing wind turbine transformer substations differ significantly from conventional substations in structural design due to their adaptation to the spatial layout and equipment capacity requirements of wind farms. This necessitates the use of ladders for operation and maintenance in certain scenarios. The specific reasons are as follows: The transformer substations at the base of wind turbines are mostly vertical and compact designs, with a typical height of 2.8-3.5m. The core components on the top of the high-voltage switchgear, such as busbars, surge arresters, and voltage transformers, are located at a height of 2.5-3.2m, exceeding the reach of an adult standing upright. Additionally, the top of the substation is equipped with forced-air cooling fans and dust filters, requiring quarterly cleaning and maintenance, which necessitates the use of ladders. Furthermore, the transformers and high / low voltage switchgear inside wind turbine transformer substations are relatively large. To allow for maintenance access, some equipment is stacked in layers. Accessing data, replacing circuit breakers, or checking wiring during maintenance requires climbing ladders for convenient operation. Without ladders, operators must tiptoe or bend over to reach these components, increasing the risk of tools falling or operational errors.

[0004] However, the conventional ladders currently used in the operation and maintenance of wind power transformer substations present significant operational inconveniences and safety risks, severely restricting maintenance efficiency and personnel safety. Specific problems include: wind farms experience high wind speeds year-round, and conventional ladders lack a dedicated fixing structure at the bottom. When placed on slopes or uneven ground around the substation, they are prone to tipping over due to wind impact or slippery surfaces. Furthermore, operators must use one hand to hold the ladder and operate it, making balance difficult. Wind power transformer substation maintenance requires carrying tools and consumables such as multimeters, insulated wrenches, cleaning brushes, and spare fuses. When climbing, operators must carry tool bags in one hand and hold the ladder in the other, increasing the difficulty of climbing and increasing the risk of tools falling. Replacing large components requires multiple trips up and down the ladder to pass the parts, impacting maintenance efficiency.

[0005] In summary, due to their structural design and the characteristics of the wind farm environment, existing wind turbine transformer substations must rely on ladders to complete some of the climbing maintenance tasks. However, conventional ladders have inherent defects such as poor stability and low efficiency, resulting in high maintenance safety risks and low work efficiency, which cannot meet the needs of large-scale wind farm maintenance. Therefore, there is an urgent need to design a special auxiliary tooling for wind turbine transformer substation maintenance scenarios to improve maintenance safety and efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary tooling for the operation and maintenance of wind power transformer substations, so as to solve the problems mentioned in the background art.

[0007] In view of the above problems, the technical solution proposed by this utility model is as follows: A wind power transformer substation maintenance auxiliary tooling includes a support platform. A counterweight is mounted on the side of the support platform, and a storage component is provided on the top surface of the counterweight for storing maintenance tools. A first fixed seat is mounted on the top surface of the support platform, and a second fixed seat is located above the first fixed seat. A driving component is provided between the first and second fixed seats to drive the second fixed seat to move vertically. The storage component is connected to the second fixed seat. Handrails are mounted on both sides of the top surface of the second fixed seat, and a backrest is connected between a pair of handrails. The support platform provides stable foundation support for the entire tooling, and the counterweight mounted on its side increases the overall weight of the tooling, preventing the tooling from... In case of tipping during use; the storage unit can pre-store various tools required for operation and maintenance, eliminating the need for operators to frequently pass tools up and down during operation and maintenance, thus reducing operational steps; the first fixed base provides an installation foundation for the drive unit, which can drive the second fixed base to achieve vertical movement, thereby sending the operator standing on the second fixed base to a suitable operation and maintenance height, meeting the operation and maintenance needs of components of different heights in wind power transformer boxes; the handrails on both sides of the top surface of the second fixed base cooperate with the backrest in between, so that when the operator sits on the second fixed base, he can hold the handrails and lean against the backrest to ensure body balance, reduce the safety risks caused by body imbalance, and thus improve the safety and convenience of the operation and maintenance process.

[0008] Furthermore, the driving component includes a pair of first connecting seats and a pair of second connecting seats mounted on the top of the first fixed base. A first connecting rod is connected inside the first connecting seat via a first rotating shaft. A second connecting rod is connected inside the second connecting seat via a second rotating shaft. A first support rod connects between the second connecting rods. A third connecting seat is mounted on the top of the first fixed base. A cylinder is connected inside the third connecting seat via a third rotating shaft, and the output end of the cylinder is connected to the first support rod. A pair of fourth connecting seats and a pair of fifth connecting seats are mounted on the bottom of the second fixed base. A third connecting rod is connected inside the fourth connecting seat via a fourth rotating shaft. A second support rod connects between the third connecting rod and the second connecting rod. A fourth connecting rod is connected inside the fifth connecting seat via a fifth rotating shaft. A third support rod connects between the fourth connecting rod and the first connecting rod. A connecting rod connects the third connecting rod and the first connecting rod via a pin. The first connecting seats on the top of the first fixed base provide a rotatable mounting base for the first connecting rod via a first rotating shaft, and the second connecting seats provide a rotatable mounting base for the second connecting rod via a second rotating shaft. The installation base; the first support rod between the second connecting rods can transmit the driving force of the cylinder to the two second connecting rods, ensuring that the two second connecting rods move synchronously; the third connecting seat provides installation and rotation support for the cylinder through the third rotating shaft, and the cylinder output end is connected to the first support rod, which can drive the second connecting rod to rotate around the second rotating shaft through telescopic movement; the fourth connecting seat at the bottom of the second fixed seat provides rotatable installation for the third connecting rod through the fourth rotating shaft, and the fifth connecting seat provides rotatable installation for the fourth connecting rod through the fifth rotating shaft; the second support rod between the third connecting rod and the second connecting rod can realize the force transmission between the two, so that the rotation of the second connecting rod can drive the movement of the third connecting rod; the third support rod between the fourth connecting rod and the first connecting rod can realize the force transmission between the two, so that the movement of the first connecting rod can drive the movement of the fourth connecting rod; the connecting rod between the third connecting rod and the first connecting rod can ensure that the movement of the two is synchronized, thereby enabling all components of the entire drive unit to work together, realizing the stable and smooth vertical lifting of the second fixed seat, avoiding tilting during the lifting process, ensuring the safety of the operator, and at the same time, accurately adjusting the lifting height to adapt to the operation and maintenance needs of different heights.

[0009] Furthermore, the storage component includes a storage box connected to a second fixed base. The top surface of the storage box has a storage cavity, and a lid is hinged to the top surface of the storage box. A handle is installed on the top surface of the lid. The storage box is connected to the second fixed base and can be raised and lowered synchronously with the second fixed base, allowing operators to easily retrieve tools from the storage box at different lifting heights without the need to transfer tools between upper and lower fixtures. The storage cavity on the top surface of the storage box provides a dedicated storage space for maintenance tools, allowing for centralized storage and preventing tools from being lost or damaged due to random placement. The lid, hinged to the top surface of the storage box, can close the storage cavity when tools are not in use, preventing foreign objects from entering the storage cavity and contaminating the tools, ensuring the cleanliness and lifespan of the tools. The handle on the top surface of the lid facilitates the opening and closing of the lid by operators, improving operational convenience and reducing the time cost of tool management and retrieval during maintenance, thereby improving maintenance efficiency.

[0010] Furthermore, a magnet is embedded in the bottom surface of the lid, and an iron sheet is embedded in the top surface of the storage box. The magnet and the iron sheet attract each other, and the magnet on the bottom surface of the lid cooperates with the iron sheet on the top surface of the storage box. When the lid is closed, the magnet will attract the iron sheet, thereby firmly fixing the lid to the top surface of the storage box. This prevents the lid from opening on its own due to bumps or wind during tool movement, and prevents tools from falling out of the storage cavity. At the same time, this attraction and fixing method does not require a complex locking structure. The operator only needs to apply a certain pulling force with the handle to open the lid. While ensuring the lid is firmly closed, it also takes into account the convenience of opening and closing, further improving the security of tool storage and the ease of access.

[0011] Furthermore, both the support platform and the counterweight are equipped with a pair of casters on their bottom surfaces, and these casters are equipped with brake pads. The casters on the bottom surfaces of the support platform and the counterweight can convert the sliding friction between the tooling and the ground into rolling friction, reducing the resistance when the tooling moves. This allows operators to easily push the tooling to any maintenance location of the wind turbine transformer without the need for multiple people to carry it, saving manpower. The brake pads on the casters can be used to lock the casters after the tooling has moved to the designated position, preventing the tooling from moving due to external forces during maintenance. This ensures the stability of the tooling position, thereby improving the safety and convenience of the maintenance process, while also increasing the flexibility of the tooling's movement and the reliability of its fixed position.

[0012] Furthermore, an anti-slip pad is installed on the top surface of the second fixed seat. The anti-slip pad on the top surface of the second fixed seat can increase the friction between the operator's feet and the top surface of the second fixed seat. When the operator sits on the second fixed seat to perform maintenance work, the anti-slip pad can also effectively prevent the operator from slipping, avoid the safety accident caused by loss of balance due to slipping, and thus improve the stability and safety of the operator on the second fixed seat, ensuring the smooth progress of maintenance work.

[0013] Furthermore, the counterweight contains a battery that powers the cylinder. The side of the counterweight has a heat dissipation groove with a filter, and a charging interface is also embedded in the side. The battery stored in the counterweight can directly power the cylinder without an external power source, freeing the tooling from dependence on external power and enabling normal operation in wind farm environments where convenient external power is unavailable, thus improving the tooling's applicability and flexibility. The heat dissipation groove with a filter on the side of the counterweight allows heat generated by the battery during operation to be dissipated to the outside, preventing the battery from overheating and reducing its lifespan or causing malfunctions. Simultaneously, the filter prevents dust, sand, and other impurities from entering the counterweight and contaminating the battery, ensuring a normal operating environment for the battery. The charging interface embedded in the side of the counterweight allows for charging the battery via an external charger when its power is low, ensuring the battery always has sufficient charge to drive the second fixed seat to rise and fall normally, thereby guaranteeing the continuous and stable operation of the tooling.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This wind power transformer substation maintenance auxiliary tool, through a support platform, counterweight, and casters with brake pads forming a stable base, replaces the simple support structure of a ladder. The support platform provides a large-area load-bearing foundation, the counterweight increases the overall weight of the tool to offset the overturning moment when a person is placed on top, and the casters are locked by brake pads after moving to the maintenance position to prevent the tool from sliding or tipping over. Compared with the two-point support of a ladder, this base design improves stability, solves the risk of ladders easily tipping over, and eliminates the need to temporarily adjust the support state based on the flatness of the ground. At the same time, the user sits on the second fixed seat and does not need to use one hand to hold the position and operate as when on a ladder. The storage box can store tools such as multimeters and insulated wrenches in advance and rises and falls with the second fixed seat. The operator does not need to carry a tool bag in one hand and hold the ladder with the other hand as when climbing a ladder, nor does he / she need to go up and down multiple times to retrieve tools during maintenance.

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-5 This utility model provides a technical solution: an auxiliary tooling for the operation and maintenance of a wind power transformer substation, including a support platform 1, a counterweight 3 mounted on the side of the support platform 1, a storage component on the top surface of the counterweight 3 for storing operation and maintenance tools, a first fixed seat 11 mounted on the top surface of the support platform 1, a second fixed seat 10 above the first fixed seat 11, a driving component between the first fixed seat 11 and the second fixed seat 10 for driving the second fixed seat 10 to move vertically, the storage component being connected to the second fixed seat 10, and handrails 7 mounted on both sides of the top surface of the second fixed seat 10, with a backrest 8 connecting the pair of handrails 7. First, the entire tooling is moved to the position of the wind power transformer substation to be maintained, with the support platform 1 contacting the ground and providing initial support for the tooling; then... The counterweight 3 is used to increase the overall stability of the tooling and prevent it from shaking or tipping over during subsequent operations. Then, the tools required for maintenance are placed in the storage compartment on the top of the counterweight 3 to prepare the tools in advance. After that, the operator sits on the top of the second fixed seat 10, holds the handrails 7 on both sides, and leans against the backrest 8 to maintain body stability. Finally, the drive mechanism between the first fixed seat 11 and the second fixed seat 10 is activated. The drive mechanism generates power and moves the second fixed seat 10 vertically upward. When the second fixed seat 10 moves to a position that matches the height of the part to be maintained, the drive mechanism is turned off, and the operator can start the maintenance work. After the work is completed, the drive mechanism is activated again to move the second fixed seat 10 vertically downward to reset it.

[0019] In one embodiment of this utility model, the driving component further includes a pair of first connecting seats 12 and a pair of second connecting seats 13 mounted on the top of the first fixed seat 11. A first connecting rod 14 is connected inside the first connecting seat 12 via a first rotating shaft. A second connecting rod 23 is connected inside the second connecting seat 13 via a second rotating shaft. A first support rod 24 is connected between the second connecting rods 23. A third connecting seat 21 is mounted on the top of the first fixed seat 11. A cylinder 22 is connected inside the third connecting seat 21 via a third rotating shaft, and the output end of the cylinder 22 is connected to the first support rod 24. The bottom of the second fixed seat 10 is... The device is equipped with a pair of fourth connecting seats 17 and a pair of fifth connecting seats 18. The interior of the fourth connecting seat 17 is connected to a third connecting rod 16 via a fourth rotating shaft. A second support rod 19 connects the third connecting rod 16 and the second connecting rod 23. The interior of the fifth connecting seat 18 is connected to a fourth connecting rod 20 via a fifth rotating shaft. A third support rod 25 connects the fourth connecting rod 20 and the first connecting rod 14. A connecting rod 15 connects the third connecting rod 16 and the first connecting rod 14 via a pin. When the second fixed seat 10 needs to be driven to rise, firstly, the cylinder 22 is energized, and the output end of the cylinder 22 begins to extend. Because the cylinder 22... The first support rod 24 is connected to the third connecting seat 21 via the third rotating shaft. During the extension of the output end, it pushes the first support rod 24 connected to it to move. Then, the first support rod 24 drives the two second connecting rods 23 connected to it to rotate outward around the second rotating shaft on the second connecting seat 13. Then, the second connecting rod 23 drives the third connecting rod 16 to rotate around the fourth rotating shaft on the fourth connecting seat 17 via the second support rod 19. At the same time, the third connecting rod 16 drives the first connecting rod 14 to rotate around the first rotating shaft on the first connecting seat 12 via the connecting rod 15. Subsequently, the first connecting rod 14 drives the fourth connecting rod 20 to rotate around the fifth connecting seat via the third support rod 25. The fifth shaft on 18 rotates; during the joint rotation of the first connecting rod 14, the second connecting rod 23, the third connecting rod 16, and the fourth connecting rod 20, they cooperate to convert the extension and retraction force of the cylinder 22 into an upward supporting force, pushing the second fixed seat 10 to rise vertically; when the second fixed seat 10 needs to descend, the output end of the cylinder 22 retracts, pulling the first support rod 24 to move in the opposite direction, which in turn drives the second connecting rod 23, the third connecting rod 16, the first connecting rod 14, and the fourth connecting rod 20 to rotate in the opposite direction in sequence, so that the second fixed seat 10 descends vertically under its own weight and the coordinated action of each component until it returns to its initial position.

[0020] As an embodiment of this utility model, the storage component further includes a storage box 4, which is connected to a second fixed base 10. The top surface of the storage box 4 has a storage cavity 5, and the top surface of the storage box 4 is also hinged to a box cover 6. A handle 9 is installed on the top surface of the box cover 6. Before performing maintenance operations, the operator first holds the handle 9 on the top surface of the box cover 6 and pulls the handle 9 upward. Since the box cover 6 is hinged to the storage box 4, the box cover 6 will rotate around the hinge and open. Then, the multimeter, insulated wrench, cleaning brush, and other tools required for maintenance are placed one by one into the storage cavity 5 on the top surface of the storage box 4. Then, the operator holds the handle 9 and rotates the box cover 6 downward until the box cover 6 closes on the top surface of the storage box 4, sealing the storage cavity 5 and completing the storage of tools. When the operator moves up and down with the second fixed base 10 to the maintenance position and needs to use the tools, the operator holds the handle 9 again to open the box cover 6, takes out the required tools from the storage cavity 5, and performs the operation. After the operation is completed, the tools are put back into the storage cavity 5 and the box cover 6 is closed.

[0021] As an embodiment of this utility model, a magnet is further embedded in the bottom surface of the lid 6 and an iron sheet is embedded in the top surface of the storage box 4. The magnet and the iron sheet are attracted to each other, and the magnet and the iron sheet are in close contact and generate a stable attraction force, which fixes the lid 6 on the storage box 4 and prevents the lid 6 from opening by itself.

[0022] As an embodiment of this utility model, further, a pair of casters 2 are installed on the bottom surfaces of both the support platform 1 and the counterweight 3, and the casters 2 are equipped with brake pads. When it is necessary to move the tooling, firstly, the operator checks the status of the brake pads of the casters 2 to ensure that the brake pads are in the released state; then, the operator pushes the handle 7 or the support platform 1 of the tooling, etc. Since the casters 2 installed on the bottom surfaces of the support platform 1 and the counterweight 3 can rotate flexibly, the tooling can be easily moved under the rolling action of the casters 2; during the movement, the direction of the pushing force can be adjusted. The swivel casters 2 are used to change the direction of the tooling movement, precisely pushing the tooling to the maintenance location of the wind turbine transformer. Once the tooling reaches the designated position, the operator steps on the brake pads of each swivel caster 2. The brake pads make close contact with the wheel body of the swivel caster 2 and generate friction, preventing the swivel caster 2 from continuing to roll, thus fixing the tooling in the current position and preventing it from moving during maintenance. When it is necessary to move the tooling again, the brake pads are stepped on in the opposite direction, causing the brake pads to separate from the wheel body, and the swivel caster 2 regains its rolling ability, allowing the tooling to be moved again.

[0023] As an embodiment of this utility model, the top surface of the second fixed seat 10 is further provided with an anti-slip pad.

[0024] As an embodiment of this utility model, the counterweight 3 further includes a battery stored inside, which powers the cylinder 22. The side of the counterweight 3 has a heat dissipation groove equipped with a filter, and a charging interface is also embedded in the side of the counterweight 3. When the cylinder 22 is needed to drive the second fixed base 10 to rise or fall, firstly, the battery establishes a circuit connection with the cylinder 22 through its internal wiring. The electrical energy inside the battery is transferred to the cylinder 22 through the wiring, providing power for the extension and retraction of the cylinder 22. During the process of the battery supplying power to the cylinder 22, the battery generates heat. At this time, the heat will be distributed in the counterweight 3. A hot airflow is generated inside, and the hot airflow flows outward through the heat dissipation grooves on the side of the counterweight 3 to dissipate heat. At the same time, the filter on the heat dissipation groove will prevent dust, sand and other impurities in the outside air from entering the interior of the counterweight 3, preventing impurities from adhering to the battery surface and affecting heat dissipation or damaging the battery. When the battery power is low, the operator inserts the charger plug into the charging port on the side of the counterweight 3. The charger charges the battery through the charging port, and electrical energy enters the battery through the charging port and is stored. After charging is completed, the charger plug is unplugged, and the battery can supply power to the cylinder 22 again.

[0025] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
