Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, in particular to a transformer protection device which is easy to replace. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization (magnetic saturation transformer). Because transformers are mostly installed outdoors, protective devices are required for the transformers.

[0003] Most of the transformers used in existing cities are installed on the ground and protected by box-type protective devices. The existing transformer protection boxes are mostly made of materials such as iron sheets, so they will accelerate rust and deformation under long-term wind and sun exposure. Therefore, they need to be replaced or inspected after long-term use. The existing box-type protective devices are mostly fixed to the outside of the transformer by welding or bolts, so replacement is extremely time-consuming and labor-intensive, and requires the use of specific tools, which brings great work intensity to the staff. Therefore, there is an urgent need for a transformer protection device that is easy to replace to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a transformer protection device that is easy to replace, so as to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a transformer protection device that is easy to replace, comprising a base plate for mounting the transformer protection device and a U-shaped protection plate for transformer protection, wherein a slide groove is transversely opened on the top surface of the base plate, and the bottom of the U-shaped protection plate is slidably connected to the inside of the two slide grooves, and two rectangular grooves are symmetrically opened on both sides of the top surface of the base plate, and sliders are slidably connected to the inside of the rectangular grooves, and the top surfaces of the two sliders are fixedly connected to side plates that are easy to disassemble and replace, and the two side plates match the openings on both sides of the U-shaped protection plate;

[0006] The top surface of the side panel is provided with a mounting groove, a card block is slidably connected in the mounting groove, a spring is fixedly connected to the bottom of the mounting groove, the end of the spring is fixedly connected to the card block, the side wall of the side panel is provided with two strip holes, a U-shaped rod is fixedly connected between the side walls of the two card blocks, and the U-shaped rod slides and extends to the outside of the strip hole, and two card slots are symmetrically provided on the top surface of the inner wall of the U-shaped protective plate.

[0007] Preferably, the side of the block close to the U-shaped protective plate is arc-shaped.

[0008] Preferably, two limiting blocks are symmetrically fixedly connected to the side wall of the clamping block, and two limiting grooves are symmetrically opened on the inner wall of the installation groove.

[0009] Preferably, the two limiting blocks fixedly connected to the side wall of the clamping block are respectively slidably connected to the inside of the two limiting grooves opened on the inner wall of the installation groove.

[0010] Preferably, a strip block is fixedly connected to the vehicle on the side wall of the sliding block, and two strip grooves are symmetrically opened on the inner wall of the rectangular groove.

[0025] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0028] like Figures 1 to 5 The main structure of a transformer protection device that is easy to replace is shown as follows: a base plate 1 for installing the transformer protection device and a U-shaped protection plate 3 for protecting the transformer. A transformer 4 is fixedly installed on the top surface of the base plate 1. The U-shaped protection plate 3 is erected above the outer side of the transformer 4, and an inspection door is opened on the side wall of the U-shaped protection plate 3. A power cord quick connector is fixedly installed on the top surface of the U-shaped protection plate 3.

[0029] The top surface of the bottom plate 1 is provided with a chute 2 transversely, and the bottom of the U-shaped protective plate 3 is slidably connected to the inside of the two chute 2 respectively. One side of the chute 2 extends to the side of the bottom plate 1 and is open, so as to facilitate the removal and installation of the U-shaped protective plate 3 from the bottom plate 1;

[0030] Two rectangular grooves 7 are symmetrically provided on both sides of the top surface of the bottom plate 1. Slide blocks 6 are slidably connected to the inside of the rectangular grooves 7. The top surfaces of the two slide blocks 6 are fixedly connected to the side panels 5 for easy removal and replacement. When the slide blocks 6 drive the side panels 5 to slide to the side walls of the U-shaped protective plate 3 and install them, the slide blocks 6 will slide to the ends of the rectangular grooves 7, thereby effectively limiting the positions of the side panels 5 and the U-shaped protective plate 3.

[0031] The two side panels 5 match the openings on both sides of the U-shaped protective plate 3. Grooves are provided on both sides of the opening of the U-shaped protective plate 3, and the side panels 5 are snapped into the inside of the grooves.

[0032] The top surface of the side panel 5 is provided with a mounting groove 8, and a card block 9 is slidably connected in the mounting groove 8. The bottom of the mounting groove 8 is fixedly connected with a spring 10, and the end of the spring 10 is fixedly connected to the card block 9. The top surface of the inner wall of the U-shaped protective plate 3 is symmetrically provided with two card grooves. The side of the card block 9 close to the U-shaped protective plate 3 is arc-shaped. Thanks to the arc-shaped setting of the side of the card block 9 close to the U-shaped protective plate 3, when the side panel 5 is pushed to move toward the U-shaped protective plate 3, when the card block 9 contacts the U-shaped protective plate 3, the card block 9 will shrink to the inside of the mounting groove 8 under the influence of the arc surface and compress the spring 10. When the card block 9 moves to the relative position of the card slot, the spring 10 will push the card block 9 to be clamped to the inside of the card slot, thereby facilitating the installation of the side panel 5;

[0033] Two strip holes are provided on the side wall of the side panel 5, and a U-shaped rod 11 is fixedly connected between the side walls of the two clamping blocks 9, and the U-shaped rod 11 slides and extends to the outside of the strip holes, and the U-shaped rod 11 on the side wall of the side panel 5 is pulled downward along the two strip holes, thereby driving the clamping blocks 9 fixedly connected at both ends to retract into the interior of the mounting groove 8 through the U-shaped rod 11, and at the same time, the spring 10 at the lower end of the clamping block 9 is compressed, so as to move the clamping block 9 out of the inside of the clamping groove provided on the inner wall of the U-shaped protective plate 3, thereby releasing the limit of the side panel 5.

[0034] The side wall of the card block 9 is symmetrically fixed with two limit blocks 12, and the inner wall of the installation groove 8 is symmetrically provided with two limit grooves. The two limit blocks 12 fixedly connected to the side wall of the card block 9 are respectively slidably connected to the inside of the two limit grooves provided on the inner wall of the installation groove 8. Thanks to the setting of the limit blocks 12, the sliding direction of the card block 9 can be effectively limited, and the stability of the card block 9 when sliding can be further improved.

[0035] The side wall of the slider 6 is fixedly connected to the car with a strip block 13, and the inner wall of the rectangular groove 7 is symmetrically opened with two strip grooves. The two strip blocks 13 fixedly connected to the side wall of the slider 6 are respectively slidably connected to the inside of the two strip grooves opened on the inner wall of the rectangular groove 7. Thanks to the two strip blocks 13 fixedly connected on the side wall of the clamping block 9 being respectively slidably connected to the inside of the two strip grooves opened on the inner wall of the rectangular groove 7, the sliding direction of the slider 6 is further limited.

[0036] A rectangular sealing gasket 14 is fixedly connected to one side of the side plate 5 close to the U-shaped protective plate 3 . The rectangular sealing gasket 14 can effectively achieve a seal between the side plate 5 and the U-shaped protective plate 3 .

[0037] How it works

[0038] When the transformer protective device is easy to replace, the U-shaped rod 11 on the side wall of the side panel 5 is pulled downward along the two strip holes, thereby driving the clamping blocks 9 fixed at both ends thereof to retract into the interior of the mounting groove 8 through the U-shaped rod 11, and at the same time compressing the spring 10 at the lower end thereof through the clamping block 9, thereby realizing moving the clamping block 9 out of the clamping groove provided on the inner wall of the U-shaped protective plate 3, thereby realizing releasing the limit of the side panel 5, and at this time pulling the U-shaped rod 11 to drive the side panel 5 away from the U-shaped protective plate 3, and at the same time driving the two sliders 6 fixedly connected at the bottom thereof to slide along the interior of the rectangular groove 7 through the side panel 5 until the sliders 6 move out of the rectangular groove 7, thereby removing the side panel 5;

[0039] When the two side panels 5 are removed from the U-shaped protective plate 3, push the U-shaped protective plate 3 to slide along the two slide grooves 2 until the U-shaped protective plate 3 moves out of the slide groove 2, so as to remove the U-shaped protective plate 3. When the protective device needs to be replaced and installed, repeat the above operation to install the new U-shaped protective plate 3 first and then install the two side panels 5, so as to replace the transformer protective device.
