Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer protection structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).

[0003] Transformers are typically installed inside a casing, and heat is dissipated from the transformer through heat sinks on the casing.

[0004] However, transformers are usually used outdoors. To prevent rainwater from corroding the transformer, a protective structure is installed on the outside of the transformer. The existing protective structure completely covers the transformer inside the protective structure, which reduces the heat dissipation effect of the transformer and affects its performance and service life. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, a transformer protection structure is provided.

[0006] The specific technical solution is as follows:

[0007] A transformer protection structure is designed, comprising a main body, a protective shell, and a movable shell. The outer wall of the main body is connected to the protective shell by fasteners. One side of the protective shell is connected to one end of a support block by fasteners. The other end of the support block is connected to the middle of a bidirectional threaded column by a rotating shaft. The bidirectional threaded column is connected to a threaded block by threads. The other end of the threaded block is connected to one side of the movable shell by fasteners. One end of a sponge block is connected to the inside of the movable shell by fasteners. The top of the sponge block is provided with an extrusion plate. A heat sink is provided on one side of the main body. The heat sink is integrally formed with the main body.

[0008] Preferably, the bidirectional threaded column is connected to the driven gear via fasteners, the driven gear meshes with the driving gear, one side of the driving gear is fastened to the output shaft of the first motor, and the first motor is fastened to the support block.

[0009] Preferably, the end of the movable shell away from the main body is connected to the photovoltaic panel via fasteners, a storage battery is provided below the photovoltaic panel, the storage battery is fastened to the movable shell, and the storage battery circuit is connected to the photovoltaic panel.

[0010] Preferably, a collection groove is provided at the bottom of the inner wall of the movable shell, and a water outlet column is provided at the bottom of the collection groove. The water outlet column penetrates the bottom of the collection groove and is connected to the bottom of the movable shell by welding.

[0011] Preferably, the top of the outer wall of the movable shell is connected to a sliding rod in a sliding manner, and the movable shell is symmetrically distributed on the main body.

[0012] Preferably, the two ends of a one-way threaded column are connected inside one side of the movable shell via a rotating shaft. The one-way threaded column is threaded to one end of the extrusion plate. One end of the one-way threaded column is fastened to the output shaft of the second motor, and the fastener of the second motor is connected to the movable shell.

[0013] Preferably, the end of the extrusion plate away from the one-way threaded post is connected to the limiting rod by sliding, and the two ends of the limiting rod are connected to the inner wall of the movable shell by fasteners.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] 1. By incorporating a movable shell and sponge blocks, the protective shell isolates rainwater from the transformer during rain or snow, preventing water or snow from corroding the main body. When the rain or snow stops, the first motor is activated. The first motor drives a gear through its output shaft, which in turn drives a bidirectional threaded column through a driven gear. The bidirectional threaded column, through its forward and reverse threads, moves two threaded blocks relative to each other. The threaded blocks then move the movable shell via a sliding rod. The movable shell causes its internal sponge blocks to embed into the heat sink, absorbing rainwater and snow. After absorption, the first motor is reversed, causing the movable frame to move the sponge blocks to one side, preventing them from affecting the heat sink's heat dissipation of the main body and preventing rainwater from remaining on the heat sink for extended periods and causing corrosion, thus effectively improving the service life of the main body.

[0016] By incorporating a squeezing plate and a collection trough, after the sponge block absorbs water from the heat sink and moves to one side of the heat sink, the second motor is activated. The second motor drives a one-way threaded column to rotate via its output shaft. The one-way threaded column, through its threads, drives the squeezing plate to move inside the moving frame. As the squeezing plate moves, it squeezes and scrapes the sponge block from top to bottom. The water droplets inside the sponge block, squeezed by the pressure, fall into the collection trough below and then flow out through the water column at the bottom of the collection trough. This effectively removes water from the sponge block and prevents water from remaining inside the sponge block for an extended period, thus demonstrating the practicality of the device.

[0024] 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.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0027] Reference Figure 1-5A transformer protection structure includes a main body 1, a protective shell 2, and a movable shell 3. The outer wall of the main body 1 is connected to the protective shell 2 via fasteners. One side of the protective shell 2 is connected to one end of a support block 13 via fasteners. The other end of the support block 13 is connected to the middle of a bidirectional threaded column 8 via a rotating shaft. The bidirectional threaded column 8 is threadedly connected to a threaded block 10. The other end of the threaded block 10 is connected to one side of the movable shell 3 via fasteners. The interior of the movable shell 3 is connected to one end of a sponge block 14 via fasteners. The top of the sponge block 14 is provided with a compression plate 18. A heat sink 6 is provided on one side of the main body 1. The heat sink 6 is integrally formed with the main body 1. In rainy or snowy weather, when rainwater drips onto the transformer, the protective shell 2 will isolate the rainwater, preventing rainwater or snowflakes from corroding the main body 1. When rain or snow stops, the first motor 9 is turned on. The first motor 9 drives the gear to rotate through the output shaft. The gear drives the bidirectional threaded column 8 to rotate through the driven gear 12. The bidirectional threaded column 8 drives the two threaded blocks 10 to move relative to each other through the forward and reverse threads. The threaded blocks 10 drive the movable shell 3 to move through the slide rod 7. The movable shell 3 drives the sponge block 14 inside it to embed into the heat sink 6, adsorbing the rainwater and snow on the heat sink 6. After adsorption is completed, the first motor 9 is controlled to rotate in the reverse direction, so that the movable frame drives the sponge block 14 to move to one side, preventing it from affecting the heat sink 6's heat dissipation of the main body 1. At the same time, it prevents rainwater from remaining on the heat sink 6 for a long time and causing corrosion, effectively improving the service life of the main body 1.

[0028] Furthermore, the bidirectional threaded column 8 is connected to the driven gear 12 via fasteners. The driven gear 12 meshes with the drive gear 20. The output shaft of the first motor 9 is connected to one side of the drive gear 20 via fasteners. The first motor 9 is connected to the support block 13 via fasteners. The motor rotates via the output shaft. The motor and the output shaft are integrated. The motor is an ECMA-C1-0604-RS servo motor.

[0029] Furthermore, the end of the movable shell 3 furthest from the main body 1 is connected to the photovoltaic panel 4 by fasteners. A storage battery 5 is provided below the photovoltaic panel 4. The storage battery 5 is fastened to the movable shell 3 and connected to the photovoltaic panel 4 by wiring. The photovoltaic panel 4 and the storage battery 5 are used to supply power to the first motor 9 and the second motor 11. The first motor 9 and the second motor 11 are both connected to the storage battery 5 by wiring. After the photovoltaic panel 4 generates electricity through sunlight, it will be stored inside the storage battery 5.

[0030] Furthermore, a collection trough 15 is provided at the bottom of the inner wall of the movable shell 3, and a water outlet column 16 is provided at the bottom of the collection trough 15. The water outlet column 16 penetrates the bottom of the collection trough 15 and is connected to the bottom of the movable shell 3 by welding. The water outlet column 16 is evenly distributed at the bottom of the movable shell 3 to guide the water discharged from the sponge block 14 and prevent the water from flowing back onto the transformer and causing corrosion to the transformer.

[0031] Furthermore, the top of the outer wall of the movable shell 3 is connected to the slide rod 7 in a sliding manner. The movable shell 3 is symmetrically distributed on the main body 1. The slide rod 7 is used to support the movable shell 3 to prevent it from tilting easily when supported only by the bidirectional threaded column 8. It is also used to limit the movable shell 3 to prevent it from rotating together when the bidirectional threaded column 8 rotates. The slide rod 7 is also connected to one side of the protective shell 2 through the support block 13.

[0032] Furthermore, the inside of one side of the movable shell 3 is connected to both ends of the one-way threaded column 19 via a rotating shaft. The one-way threaded column 19 is connected to one end of the extrusion plate 18 via a thread. One end of the one-way threaded column 19 is fastened to the output shaft of the second motor 11. The second motor 11 is fastened to the movable shell 3. The limiting rod 17 is used to support the extrusion plate 18 so that both ends of the extrusion plate 18 can move simultaneously. The sponge block 14 is a foamed plastic polymer sponge made of polyurethane and other plastic materials.

[0033] Furthermore, the end of the extrusion plate 18 away from the one-way threaded post 19 is connected to the limiting rod 17 by sliding. The two ends of the limiting rod 17 are connected to the inner wall of the moving shell 3 by fasteners. The extrusion plate 18 is used to extrude the sponge block 14 so that the water inside can flow into the collection tank 15 at the bottom. By setting the collection tank 15 and the water outlet column 16, the water inside the sponge block 14 is prevented from flowing directly through the moving shell 3 to the moving body 1 and splashing onto the main body 1.

[0034] Working Principle: When using this device, rainwater or snowflakes first fall onto the transformer. The protective shell 2 isolates the rainwater, preventing it from corroding the main body 1. When the rain or snow stops, the first motor 9 is turned on. The first motor 9 drives the gear to rotate via the output shaft. The gear drives the bidirectional threaded column 8 to rotate via the driven gear 12. The bidirectional threaded column 8 drives two threaded blocks 10 to move relative to each other via the forward and reverse threads. The threaded blocks 10 drive the moving shell 3 to move via the slide rod 7. The moving shell 3 causes the sponge block 14 inside it to embed into the heat sink 6, absorbing the rainwater and snow on the heat sink 6. After absorption is complete, the first motor 9 is controlled to rotate in the reverse direction, causing... The moving frame moves the sponge block 14 to one side to prevent it from affecting the heat dissipation of the heat sink 6 to the main body 1, and at the same time prevents rainwater from remaining on the heat sink 6 for a long time and causing corrosion. After the sponge block 14 absorbs the water on the heat sink 6 and moves to one side of the heat sink 6, the second motor 11 is turned on. The second motor 11 drives the one-way threaded column 19 to rotate through the output shaft. The one-way threaded column 19 drives the extrusion plate 18 to move inside the moving frame through the thread. The extrusion plate 18 moves and squeezes and scrapes the sponge block 14 from top to bottom. The water droplets inside the sponge block 14 fall into the collection tank 15 below due to the extrusion, and then flow to the outside through the water column 16 at the bottom of the collection tank 15, thus completing the work.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
