Description

Technical Field

[0001] This utility model belongs to the technical field of transformer protection equipment, and particularly relates to transformer protection devices. Background Technology

[0002] Transformer protection devices are mainly used to protect transformers from the influence of external environment and internal faults, ensuring their safe and stable operation.

[0003] Existing transformer protection devices typically include a support rod set on the ground, a crossbar mounted on the support rod, and a top plate mounted on top of the support rod. The top plate is located above the transformer. When in use, workers install the top plate on top of the support rod to protect the transformer.

[0004] However, during use, when the size of the transformer increases, it is necessary for staff to use protective devices of different sizes to protect the equipment. In this case, staff need to replace the protective devices, which is time-consuming and laborious, reduces the versatility of the device, and does not meet people's needs. Therefore, a protective device for transformers is proposed. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the existing technology by providing a transformer protection device. It not only meets the basic requirements for protecting transformers, but also allows for overall adjustment of the device through an adjustment mechanism, thereby accommodating transformers of different sizes. This saves time and effort, improves the versatility of the device, and meets people's usage needs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a transformer protection device, including a base plate, characterized in that: a first-shaped plate is respectively provided on the front and rear sides of the top of the base plate, and a support rod is respectively provided at both ends of the inner of the two first-shaped plates; a second-shaped plate is respectively provided on the top of the two front support rods and the top of the two rear support rods; a fixing block is respectively provided on the top of the two second-shaped plates; an upward-opening sliding groove is respectively provided in the middle of the two fixing blocks; two sliders are slidably arranged inside the two sliding grooves; a U-shaped plate is respectively provided on the top of the four sliders; a connecting rod is hinged inside the four U-shaped plates; and a U-shaped frame is hinged on the top of the two front connecting rods and the top of the two rear connecting rods.

[0007] As a further improvement of this utility model, two connecting blocks are respectively provided on the top of the four connecting rods, a top plate one is provided on the top of the four connecting blocks on the left side, a top plate two is provided on the top of the four connecting blocks on the right side, a support block is provided on the top of the two U-shaped frames, and a top plate three is provided on the top of the two support blocks. The tops of the top plate one, top plate two, and top plate three are coated with anti-rust paint.

[0008] The connection blocks facilitate the installation of top plate one and top plate two by the staff, while the support blocks facilitate the installation of top plate three, thus making it easier to protect the transformer body from wind and rain.

[0009] As a further improvement of this utility model, multiple connecting holes 1 are respectively provided on the two mold plates 1, and multiple connecting holes 2 are respectively provided on the mold plates 2. The transformer body is provided on the top of the base plate. Bidirectional lead screws passing through the slider are rotatably provided inside the two slide grooves. The bidirectional lead screws are screwed to the sliders. Pulleys are provided on the right ends of the two bidirectional lead screws. A belt is provided between the two pulleys. A handwheel is provided on the left side of the front bidirectional lead screw. Round holes are provided at both ends of the four support rods.

[0010] As a further improvement of this utility model, a bolt corresponding to the round hole is provided on the first mold plate, and a nut corresponding to the bolt is provided on the first mold plate. A bolt corresponding to the round hole is provided on the second mold plate, and a nut corresponding to the bolt is provided on the second mold plate.

[0011] The installation of the equipment is made more stable by using bolts one and two.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This design incorporates a handwheel. Rotating the handwheel drives the front double-acting screw to rotate, which in turn drives the front pulley to rotate. This, in turn, drives the rear pulley to rotate via a belt. Simultaneously, the rear double-acting screw rotates. The rotation of both double-acting screws causes the slider to slide within the groove, which in turn rotates the connecting rod on the U-shaped plate. The connecting rod also rotates within the U-shaped frame, thus changing the coverage area of ​​the base plate and providing protection for transformer bodies of different sizes.

[0024] How to use this utility model:

[0025] When in use, the staff first places the first mold plate 101 and the second mold plate 103 on the top of the base plate 104. At this time, the transformer body 113 is also on the top of the base plate 104. Then, the staff makes sure that the round hole on the support rod 102 corresponds to the first connection hole 111 on the first mold plate 101 and the second connection hole 112 on the second mold plate 103 according to the size of the transformer body 113. Then, the staff screws the first bolt 203 and the second bolt 205 onto the first mold plate 101 and the second mold plate 103.

[0026] At this point, the worker welds the fixing block 105 to the top of the mold plate 103. Then, the worker manually turns the handwheel 202. The rotation of the handwheel 202 drives the front double-acting screw 119 to rotate. The rotation of the front double-acting screw 119 drives the front pulley 120 to rotate, which in turn drives the rear pulley 120 to rotate via the belt 201. At the same time, the rear double-acting screw 119 rotates. The rotation of the two double-acting screws 119 drives the slider 107 to slide inside the slide groove 106, and at the same time drives the connecting rod 109 on the U-shaped plate 108 to rotate. The connecting rod 109 rotates inside the U-shaped frame 110, thereby changing the coverage area of ​​the base plate 104.
