Description

Technical Field

[0001] The utility model belongs to the technical field related to oil pool top pressing, in particular to a light main transformer oil pool top pressing prefabricated component. Background Art

[0002] The accident oil pool is one of the important buildings in the substation. The accident oil pool of the substation is to prevent the main transformer and other oil-filled electrical equipment from leaking oil and causing fires. The accident oil pool can allow the leaked oil to flow smoothly out of the tank group and flow into the accident liquid storage pool. It prevents the leaked oil from exploding, thereby protecting the substation equipment and the personal safety of the staff. Therefore, when the oil pool is in use, the top of the oil pool will be capped. In order to ensure that the top does not appear to be lifted, it is necessary to use the top prefabricated components.

[0003] However, the prefabricated capping components used on the top of the oil pool cannot be adjusted according to the area of ​​the top of the oil pool because they do not have the function of adjusting the pressing area, which will affect the capping effect. At the same time, the prefabricated capping structure used cannot control the weight and cannot adjust the force used for capping according to work needs. To this end, we provide a lightweight main transformer oil pool capping prefabricated component to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a prefabricated pressure-top component for the oil pool of a light main transformer, by which a movable pressure plate is moved in the internal position of a receiving port, so as to realize an adjustable pressure-top area of ​​the pressure-top pressing component on the top of the oil pool, and at the same time, the coordinated use of a counterweight ring and a hanging rod can realize the control of the number of counterweight rings according to work needs, so as to adjust the force used for the pressure-top.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a prefabricated component for pressing the top of a light main transformer oil pool, comprising a U-shaped pressing plate; the front and rear parts of the bottom of the U-shaped pressing plate are provided with receiving openings, the interior of the receiving openings are provided with movable pressing plates, the front and rear parts of the opposite end faces of the two movable pressing plates are provided with adjustment holes, the end faces of the receiving openings are fixed with limit rods inserted in the internal positions of the adjustment holes, the left and right end faces of the U-shaped pressing plate are fixed with electric lifting rods, a hanging rod is provided in the middle of the upper end face of the U-shaped pressing plate, and the peripheral side of the hanging rod is sleeved with a plurality of counterweight rings linearly evenly distributed from top to bottom.

[0007] The utility model is further configured that the interior of the limiting rod is provided with a curved hole penetrating the left and right end surfaces of the U-shaped pressing plate, and the left and right ends of the U-shaped pressing plate are fixed with two curved cylinders respectively connected with the curved holes.

[0008] The utility model is further configured that the end faces of the limiting rods are all provided with limiting holes connected with the inside of the bending hole, and the inner end faces of the adjusting holes are all fixed with moving rods passing through the inner position of the limiting holes.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0028] See also Figure 1-5 The utility model is a prefabricated component for pressing the top of the oil pool of a light main transformer. The movable pressing plate 5 is moved in the internal position of the receiving port 101 to adjust the pressing area of ​​the pressing component on the top of the oil pool. At the same time, the counterweight ring 4 and the hanging rod 2 are used in coordination to control the number of the counterweight rings 4 according to work needs, thereby adjusting the force used for pressing the top.

[0029] Specifically, a U-shaped pressure plate 1; a storage opening 101 is provided at the front and rear parts of the bottom of the U-shaped pressure plate 1, and a movable pressure plate 5 is arranged inside the storage opening 101; adjustment holes 501 are provided at the front and rear parts of the opposite end surfaces of the two movable pressure plates 5; the end surfaces of the storage opening 101 are fixed with limit rods 102 inserted in the internal position of the adjustment holes 501; electric lifting rods 3 are fixed to the left and right end surfaces of the U-shaped pressure plate 1; a hanging rod 2 is provided in the middle of the upper end surface of the U-shaped pressure plate 1, and a plurality of counterweight rings 4 are arranged linearly evenly from top to bottom on the circumference of the hanging rod 2; a plurality of ball openings 504 are arranged linearly evenly from front to back on the front and rear parts of the lower end surface of the movable pressure plate 5, and a ball block 503 whose circumference is flush with the bottom surface of the U-shaped pressure plate 1 is slidably arranged inside the ball opening 504.

[0030] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when it is necessary to adjust the pressing area of ​​the U-shaped pressing plate 1, the movable pressing plate 5 can be directly controlled to move inside the receiving port 101, so that the two movable pressing plates 5 move relative to or oppositely. When the movable pressing plate 5 moves out from the inside of the receiving port 101, the pressing area of ​​the entire pressing prefabricated component can be expanded at this time, thereby improving the pressing efficiency. At the same time, when controlling the pressing force of the U-shaped pressing plate 1 itself, multiple counterweight rings 4 can be moved upward on the circumference of the hanging rod 2 or multiple counterweight rings 4 can be directly sleeved on the hanging rod 2. In this way, the weight of the U-shaped pressing plate 1 itself can be increased or decreased, thereby increasing or decreasing the pressing force of the U-shaped pressing plate 1 on the top of the oil pool. At the same time, when the movable pressing plate 5 slides in the internal position of the receiving port 101, the movable pressing plate 5 will drive the ball block 503 to rotate in the internal position of the ball port 504, so the ball block 503 improves the movement efficiency of the movable pressing plate 5 and reduces the friction suffered by the movable pressing plate 5. Specific embodiment 2

[0032] See also Figure 3 , 4 6. On the basis of the specific embodiment 1, the air inside the bending cylinder 104 and the bending hole 105 is compressed by the electric lifting rod 3, so that the movable pressing plate 5 can move quickly.

[0033] Specifically, the interior of the limiting rod 102 is provided with a curved hole 105 that passes through the left and right end faces of the U-shaped pressure plate 1, and the left and right ends of the U-shaped pressure plate 1 are fixed with two curved tubes 104 that are respectively connected to the curved hole 105. The end faces of the limiting rod 102 are provided with a limiting hole 106 that is connected to the interior of the curved hole 105, and the inner end faces of the adjusting hole 501 are fixed with a moving rod 505 that passes through the internal position of the limiting hole 106. The end faces of the moving rod 505 that are inside the curved hole 105 are fixed with piston blocks 502, and the piston blocks 502 are tightly fitted with the inner side walls of the curved hole 105, and the moving ends of the electric lifting rod 3 are piston-arranged at the internal positions of the curved hole 105.

[0034] The operation process of this embodiment is as follows: when the electric lifting rod 3 is controlled to work, the electric lifting rod 3 will compress the air inside the bending cylinder 104, so that the air inside the bending cylinder 104 will push the piston block 502 to slide inside the bending hole 105, and thereby control the moving rod 505 to slide inside the limiting hole 106, so that the movable pressure plate 5 slides outward inside the receiving port 101, and at the same time, when the electric lifting rod 3 retracts, the piston block 502 will be reset, thereby resetting the movable pressure plate 5 to the receiving port 101. Specific embodiment three

[0036] See also Figure 2 , 3 On the basis of the first specific embodiment, by inserting the positioning rod 202 into the positioning opening 103, the hanging rod 2 can be easily assembled and disassembled.

[0037] Specifically, a positioning hole 103 is opened in the middle position of the upper end surface of the U-shaped pressure plate 1, and a positioning rod 202 is fixed on the lower end surface of the hanging rod 2 and inserted into the internal position of the positioning hole 103. A circular plate 201 is fixed on the peripheral wall of the hanging rod 2 above the bottom surface of the U-shaped pressure plate 1, and the counterweight ring 4 is located above the circular plate 201.

[0038] The operation process of this embodiment is: by inserting the positioning rod 202 into the positioning hole 103, the positioning hole 103 limits the positioning rod 202, so that the hanging rod 2 is stably assembled at the bottom position of the U-shaped pressure plate 1. At the same time, when the hanging rod 2 needs to be disassembled, the support plate can be lifted downward to make the support plate drive the hanging rod 2 to move upward, and thereby drive the positioning rod 202 to move out of the inside of the positioning hole 103, and the hanging rod 2 can be disassembled.
