Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, and in particular to a ring-shaped fixed support for a water spray pipe of a transformer oil tank in a power plant. Background Technology
[0002] Fire protection design codes require that transformers in thermal power plants be equipped with water spray systems for fire suppression. For the transformer body, the water spray pipes need to be fixed. However, fixing the water spray pipes on the oil tank above the transformer is difficult. Since the transformer body is below the oil tank, it cannot be fixed in the same way as the transformer body's support pillars. Therefore, a ring-shaped fixing bracket for the water spray pipes of the oil tank of the power plant transformer is used.
[0003] Traditional ring-shaped fixed supports for water spray pipes in transformer oil conservator of power plants are inconvenient to fix and support, which can damage the pipes over time. They also make it difficult to maintain the oil conservator, resulting in low applicability in use. Utility Model Content
[0004] The purpose of this utility model is to provide a ring-shaped fixing bracket for the water spray pipe of the transformer oil conservator in a power plant, so as to solve the defect of the existing ring-shaped fixing bracket for the water spray pipe of the transformer oil conservator in a power plant being inconvenient to fix.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ring-shaped fixed support for a water spray pipe of a transformer oil conservator in a power plant, comprising an angle steel support and a riser;
[0006] A vertical pipe is fixed to the top of the angle steel bracket, and a fixing structure is provided at the bottom of the angle steel bracket.
[0007] The fixing structure includes through holes extending through both sides of the bottom of the angle steel bracket. Round steel bars are inserted through the interior of each through hole. External threads are provided on the outer walls of both ends of the round steel bars, and fixing nuts are engaged with the outer sides of the external threads.
[0008] The top of the riser is fixed with a pressing structure.
[0009] When using this device, the fixed structure facilitates its support, thereby improving the applicability of the annular fixed support for the transformer oil conservator water spray pipe in the power plant. The compression structure also facilitates its anti-sway function, thereby improving the stability of the annular fixed support for the transformer oil conservator water spray pipe in the power plant during use.
[0010] Preferably, an anti-slip pad is bonded to the inner side of the angle steel bracket. The anti-slip pad increases the friction between the angle steel bracket and the oil reservoir.
[0011] Preferably, the round steel and angle steel brackets form a sliding structure through through holes. Under the action of external threads and fixing nuts, the round steel and angle steel brackets are fixed to each other, thereby fixing the angle steel brackets to the oil tank.
[0012] Preferably, the through holes are symmetrically distributed on both sides of the bottom of the angle steel bracket. This facilitates the support of the water spray pipe and further facilitates the maintenance of the oil tank.
[0013] Preferably, the pressing structure includes a first support base, a rubber pad, a second support base, a first threaded post, a threaded sleeve, and a second threaded post. The first support base is fixed to the top of the riser. The second threaded post is fixed to both sides of the first support base. The outer side of the top of the second threaded post is threaded with a threaded sleeve. The top of the threaded sleeve is threaded with the first threaded post. The second support base is provided above the first support base. Rubber pads are fixed to both sides of the top of the first support base and both sides of the bottom of the second support base.
[0014] Preferably, the threads on the outer sides of the first and second threaded posts are in opposite directions. The rubber pad increases the friction between the water spray pipe and the first and second support seats. Rotating the threaded sleeve, due to the opposite threads on the outer sides of the first and second threaded posts, causes them to move in opposite directions.
[0015] Preferably, the top end of the first threaded post extends to the outside of the threaded sleeve and is fixedly connected to one side of the second support. This changes the distance between the second support and the first support, thereby enabling the fixation of water spray pipes of different sizes and preventing the water spray pipes from shaking.
[0016] The advantages of the annular fixing bracket for the water spray pipe of the transformer oil conservator in the power plant provided by this utility model are as follows:
[0017] By setting a fixed structure, the friction between the angle steel bracket and the oil tank is increased under the action of the anti-slip pad. Under the action of the external thread and the fixing nut, the round steel and the angle steel bracket are fixed to each other, and then the angle steel bracket and the oil tank are fixed to each other. This makes it convenient to support the water spray pipe and further facilitates the maintenance of the oil tank. This realizes the function of easy support of the device, thereby improving the applicability of the annular fixed bracket for the water spray pipe of the transformer oil tank in the power plant.
[0018] By incorporating a pressing structure, the friction between the water spray pipe and the first and second support seats is increased under the action of the rubber pad. Rotating the threaded sleeve, with the threads on the outer sides of the first and second threaded posts moving in opposite directions, causes the first and second threaded posts to move in opposite directions, thereby changing the distance between the second and first support seats. This allows for the fixation of water spray pipes of different sizes, preventing the water spray pipes from shaking. This achieves the anti-shaking function of the device, thus improving the stability of the annular fixed bracket for the water spray pipe of the transformer oil conservator in the power plant during use.

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.
[0026] Please see Figures 1-5This utility model provides a ring-shaped fixed support for a water spray pipe of a transformer oil conservator in a power plant, including an angle steel support 1 and a riser 3. The riser 3 is fixed at the top of the angle steel support 1, and a fixing structure 2 is provided at the bottom of the angle steel support 1. The fixing structure 2 includes through holes 202 penetrating both sides of the bottom of the angle steel support 1. Round steel 201 penetrates the interior of each through hole 202. External threads 204 are provided on the outer walls of both ends of the round steel 201. Fixing nuts 203 are engaged and connected to the outer sides of the external threads 204. The round steel 201 and the angle steel support 1 form a sliding structure through the through holes 202. The through holes 202 are symmetrically distributed on both sides of the bottom of the angle steel support 1. An anti-slip pad is bonded to the inner side of the angle steel support 1.
[0027] Reference Figure 2 and Figure 3 As shown, by fitting the angle steel bracket 1, which matches the oil conservator, onto the outside of the oil conservator, the friction between the angle steel bracket 1 and the oil conservator is increased under the action of the anti-slip pad. At this time, the round steel 201 is passed through the inside of the through hole 202. Under the action of the external thread 204 and the fixing nut 203, the round steel 201 and the angle steel bracket 1 are fixed to each other, thereby fixing the angle steel bracket 1 and the oil conservator to each other, which facilitates the support of the water spray pipe and further facilitates the maintenance of the oil conservator.
[0028] A pressing structure 4 is fixed to the top of the riser 3. The pressing structure 4 includes a first support 401, a rubber pad 402, a second support 403, a first threaded post 404, a threaded sleeve 405, and a second threaded post 406. The first support 401 is fixed to the top of the riser 3. The second threaded post 406 is fixed to both sides of the first support 401. The outer side of the top of the second threaded post 406 is threaded with a threaded sleeve 405. The top of the threaded sleeve 405 is threaded with the first threaded post 404. The second support 403 is provided above the first support 401. The rubber pads 402 are fixed to both sides of the top of the first support 401 and both sides of the bottom of the second support 403. The threads of the first threaded post 404 and the second threaded post 406 are opposite in direction. The top of the first threaded post 404 extends to the outside of the threaded sleeve 405 and is fixedly connected to one side of the second support 403.
[0029] Reference Figure 4 and Figure 5As shown, by placing the water spray pipe on the top of the first support 401 and rotating the threaded sleeve 405, the threads on the outer sides of the first threaded post 404 and the second threaded post 406 move in opposite directions, thereby changing the distance between the second support 403 and the first support 401. This causes the second support 403 to press the rubber pad 402 against the top of the water spray pipe. Under the action of the rubber pad 402, the friction between the water spray pipe and the first support 401 and the second support 403 is increased, thus fixing water spray pipes of different sizes and preventing the water spray pipe from shaking.
