Description

Technical Field

[0001] The present application relates to the technical field of box-type transformer equipment, and specifically relates to a protection device for box-type transformer equipment. Background Art

[0002] The box-type transformer equipment, namely the box-type substation (usually called box transformer), is a closed-type power transformation equipment mainly used for voltage transformation in the power system. It converts high-voltage electricity into low-voltage electricity for low-voltage users. The box-type substation usually has air-cooling pipes for heat dissipation.

[0003] Currently, the air-cooling pipes on the box-type substation are generally fixedly installed, and the ventilation openings are always exposed. This allows dust, sand, rain, snow and other substances to enter the air-cooling pipes when the air-cooling pipes are not working, resulting in pollution of the air-cooling pipes and even damage to the equipment, and it is difficult to dynamically adjust the opening and closing state of the air-cooling pipes according to the actual working conditions of the equipment. Utility Model Content

[0004] In view of this, the purpose of the present utility model is to solve the drawbacks in the background art and propose a protection device for box-type transformer equipment to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the present utility model provides a protection device for box-type transformer equipment, including an equipment box. An air-cooling pipe is detachably installed inside the equipment box. A clamping mechanism is arranged on the equipment box. A fixing frame is fixedly connected to the equipment box. A guiding cylinder is fixedly connected to the outer surface of the fixing frame. A displacement rod is slidably connected to the inner surface of the guiding cylinder through a pushing and pulling mechanism. A rubber plug is arranged at one end of the displacement rod close to the air-cooling pipe.

[0006] Preferably, the clamping mechanism includes a retaining platform fixedly installed on the equipment box. A table shaft is fixedly penetrated through the inside of the retaining platform. Through the clamping mechanism, the air-cooling pipe can be relatively stably clamped, so that it can rotate during the process of not axially moving.

[0007] Preferably, a clamping frame is rotatably connected to the outer surface of the table shaft, and a roller is rotatably connected to the inside of the clamping frame.

[0008] Preferably, a screw rod is threadedly connected to the top of the retaining platform, and a rotating handle is arranged at the top of the screw rod.

[0009] Preferably, the pushing and pulling mechanism includes a frame shaft fixedly penetrated through the inside of the fixing frame. A handle is rotatably connected to the outer surface of the frame shaft. A first piece shaft is fixedly penetrated through the inside of the handle. Through the pushing and pulling mechanism, the rubber plug can block the ventilation opening of the air-cooling pipe when the air-cooling pipe is not in use.

[0010] Preferably, a driving piece is rotatably connected to the outer surface of the first piece of shaft. The end of the shifting rod far from the rubber plug is fixedly penetrated with a second piece of shaft, and the outer surface of the second piece of shaft is rotatably connected to the end of the driving piece far from the first piece of shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. For this box-type substation equipment protection device, when the air-cooling pipe is not in use, the air inlet of the air-cooling pipe can be sealed with a rubber plug through the pushing and pulling mechanism, thus effectively preventing sundries such as dust, sand, rain and snow from entering the air-cooling pipe. The opening and closing state of the air-cooling pipe can be dynamically adjusted according to the actual working conditions of the equipment.

[0018] Next, the technical solutions in the embodiments of this application will be clearly and completely described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0019] Please refer to Figures 1-3, a protection device for box-type substation equipment, including an equipment box 1, an air-cooling pipe 2 is detachably installed inside the equipment box 1, a clamping mechanism is arranged on the equipment box 1, a fixing frame 9 is fixedly connected to the equipment box 1, a guiding cylinder 10 is fixedly connected to the outer surface of the fixing frame 9, a shifting rod 11 is slidably connected to the inner surface of the guiding cylinder 10 through a pushing and pulling mechanism, and a rubber plug 12 is arranged at one end of the shifting rod 11 close to the air-cooling pipe 2.

[0020] Through the above technical solution, during the use of the box-type substation, the air-cooling pipe 2 can be relatively stabilized by the clamping mechanism, and when the air-cooling pipe 2 is not in use, the rubber plug 12 can be inserted into the air-cooling pipe 2 through the pushing and pulling mechanism to block it.

[0021] Specifically, the clamping mechanism includes a retaining platform 3 fixedly installed on the equipment box 1, and a table shaft 4 is fixedly penetrated through the inside of the retaining platform 3.

[0022] Through the above technical solution, both the retaining platform 3 and the clamping frame 5 have concave designs, which are designed to adapt to the air-cooling pipe 2 and better clamp the air-cooling pipe 2 relatively stably.

[0023] Specifically, a clamping frame 5 is rotatably connected to the outer surface of the table shaft 4, and a roller 6 is rotatably connected to the inside of the clamping frame 5.

[0024] Through the above technical solution, the clamping frame 5 and the roller 6 can relatively stably clamp the air-cooling pipe 2, preventing the air-cooling pipe 2 from axially moving, but allowing the air-cooling pipe 2 to rotate and adjust.

[0025] Specifically, a screw rod 7 is threadedly connected to the top of the retaining platform 3, and a rotating handle 8 is arranged at the top of the screw rod 7.

[0026] Through the above technical solution, the screw rod 7 passes through the inside of the clamping frame 5, and the screw rod 7 can be screwed out from the retaining platform 3.

[0027] Specifically, the pushing and pulling mechanism includes a frame shaft 13 fixedly penetrated through the inside of the fixing frame 9, a handle 14 is rotatably connected to the outer surface of the frame shaft 13, and a first piece shaft 15 is fixedly penetrated through the inside of the handle 14.

[0028] Through the above technical solution, when pushing and pulling the handle 14, it can rotate along the frame shaft 13, causing the two driving pieces 16 to deflect, and the driving pieces 16 will drive the shifting rod 11 during the deflection process.

[0029] Specifically, a driving piece 16 is rotatably connected to the outer surface of the first piece shaft 15, a second piece shaft 17 is fixedly penetrated through the end of the shifting rod 11 away from the rubber plug 12, and the outer surface of the second piece shaft 17 is rotatably connected to the end of the driving piece 16 away from the first piece shaft 15.

[0030] Through the above technical solution, the first shaft 15 and the second shaft 17 cooperate to drive the displacement piece 16, which can push and pull the displacement rod 11 so that it moves along a fixed track under the relative limit of the guide cylinder 10.

[0031] Working principle: During the use of the box-type substation, the air-cooling pipe 2 can be relatively stabilized through the clamping mechanism, that is, the air-cooling pipe 2 is placed on two sets of retaining platforms 3. At the same time, the clamping frame 5 is rotated along the platform shaft 4, so that the rollers 6 inside the clamping frame 5 abut against the air-cooling pipe 2. Then, the screw rod 7 is passed through the clamping frame 5, and the rotating handle 8 is rotated to drive the screw rod 7 to rotate. During the rotation of the screw rod 7, it will gradually penetrate into the retaining platform 3. During this period, the rotating handle 8 will gradually abut against the other end of the clamping frame 5 and move downward until the rollers 6 inside the clamping frame 5 tightly abut against the air-cooling pipe 2, thereby relatively limiting it and preventing the axial displacement of the air-cooling pipe 2. When adjusting the self-rotation of the air-cooling pipe 2, there is no need to disassemble the clamping frame 5. Just rotate the air-cooling pipe 2, and the air-cooling pipe 2 can rotate smoothly through the rotation of the rollers 6. The smooth self-rotation of the air-cooling pipe 2 helps to eliminate the hot spots inside the equipment, improve the operation stability of the equipment, and avoid failures caused by local overheating. No other components need to be disassembled during the whole adjustment process, effectively improving the operation efficiency. When the air-cooling pipe 2 is not needed to assist in heat dissipation, the handle 14 can be pushed. During this process, the handle 14 will rotate along the frame shaft 13, and the handle 14 will drive the displacement piece 16 to deflect through the first shaft 15 during the forward push. At the same time, under the action of the second shaft 17, the displacement rod 11 is pushed, so that the displacement rod 11 slides along the guide cylinder 10 until the displacement rod 11 stably inserts the rubber plug 12 into the air-cooling pipe 2, thereby preventing sundries such as dust, sand, rain and snow from entering the air-cooling pipe 2 and causing pollution or even damage to the equipment.

[0032] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
