Description

Technical Field

[0001] This utility model relates to the field of protection equipment technology, and in particular to a multiple safety protection device for a power transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. When in use, a transformer can be protected by protective devices to prevent damage from external forces.

[0003] Existing transformers are generally divided into outdoor and indoor uses. When used outdoors, protective equipment is often required. Typically, the protective equipment is installed by mounting the base on an external device or object, then installing the transformer inside the base, connecting the wires to the transformer through the wiring holes, and finally fixing the protective cover to the base with screws to enclose the transformer, thus achieving the safety protection of the transformer.

[0004] However, since the diameter of the wire hole is mostly larger than the diameter of the wire, the wire may sway when affected by strong winds. This can cause the wire end at the connection between the wire and the transformer to sway along with the wire, resulting in the wire end at the connection becoming loose and falling off due to the continuous shaking, thus affecting the stability of the connection between the wire and the transformer. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-safety protection device for power transformers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-safety protection device for a power transformer, comprising a base, a protective cover on one side of the base, multiple heat dissipation holes on one side of the base, multiple wire-passing holes on one side of the base, a limiting device on the side of the base near the wire-passing holes for positioning and reinforcing the wires inserted into the wire-passing holes and preventing the wires from shaking, and an interception device on one side of the base for blocking falling or impacting objects that are about to hit the surface of the base or the protective cover.

[0007] The effect achieved by the above components is as follows: first, the base is installed on external equipment or objects, then the transformer is installed inside the base, then the wires are connected to the transformer through the wire hole, and then the protective cover is fixed to the base with screws to enclose the transformer, thereby achieving safety protection for the transformer.

[0008] Preferably, the limiting device includes a hollow plate, which is fixedly connected to the inner wall of the base near the wire hole. A through hole is formed on one side of the hollow plate, with the inner wall of the through hole penetrating the hollow plate. A rectangular hole is formed on one side of the hollow plate. Two rectangular cylinders are symmetrically fixedly connected to the inner wall of the hollow plate. Each of the two rectangular cylinders has a locking block slidably connected to its inner wall. A spring rod is fixedly connected to one side of each locking block. The surfaces of the two spring rods are slidably connected to the inner walls of the two rectangular cylinders. A spring in one of the two spring rods... The other end is fixedly connected to the inner wall of two rectangular tubes respectively. Two circular hole plates are symmetrically slidably connected to the inner wall of the hollow plate. Rubber blocks are fixedly connected to the adjacent side of the two circular hole plates. T-shaped plates are fixedly connected to one side of the two circular hole plates. The surfaces of the two T-shaped plates are slidably connected to the inner wall of the rectangular hole. Multi-hole rods are fixedly connected to the side of the two circular hole plates away from the rubber blocks. The two locking blocks are located inside the two multi-hole rods respectively. The surface size and shape of the locking blocks are adapted to the size and shape of the inner wall of the multi-hole rods.

[0009] The effect achieved by the above components is as follows: By setting a limiting device, the wire is first inserted through the wire hole and passes through the round hole, so that a part of the wire is located inside the hollow plate, and the wire is positioned between the two rubber blocks. At this time, the two T-shaped plates are manually moved, causing the two T-shaped plates to move in opposite directions, which in turn causes the two round hole plates to move in opposite directions, which in turn causes the two round hole plates to move in opposite directions, which in turn causes the two round hole plates to move in opposite directions, causing the two round hole rods to press against the two locking blocks, causing the two locking blocks to move inward towards the inside of the two rectangular cylinders. When the two rubber blocks move in opposite directions to the position where they simultaneously press against the surface of the wire, the spring in the spring rod... Under the action of force, the two spring rods simultaneously drive the two locking blocks to move closer to the multi-hole rods. When the two locking blocks move to the corresponding positions inside the holes of the two multi-hole rods, the two locking blocks limit the two multi-hole rods, which in turn limit the two round hole plates and the two rubber blocks. This causes the two rubber blocks to stick together and clamp the wire, thereby achieving the limitation and reinforcement of the wire. This reduces the swaying of the wire when affected by strong winds, which would cause the wire end at the connection between the wire and the transformer to sway along with the wire. This could lead to the wire end at the connection loosening and falling off under continuous shaking, thus improving the connection stability between the wire and the transformer.

[0010] Preferably, anti-slip pads are fixedly connected to one side of both T-shaped plates, and the surfaces of both anti-slip pads are provided with multiple anti-slip protrusions.

[0011] The effect achieved by the above components is that by setting up anti-slip pads, the anti-slip pads can increase the contact friction between the T-shaped plate and the hand, reducing the chance of the hand slipping when manually pushing the T-shaped plate.

[0012] Preferably, multiple rubber protrusions are fixedly connected to adjacent sides of the two rubber blocks, and the multiple rubber protrusions are arranged at equal distances.

[0013] The effect achieved by the above components is as follows: by setting rubber bumps, the rubber bumps can increase the resistance and adhesion between the rubber block and the surface of the wire, further increasing the stability of the rubber block in clamping the wire and reducing the possibility of the wire slipping.

[0014] Preferably, a positioning rod is fixedly connected to the inner wall of the hollow plate, and the inner walls of the two perforated plates are slidably connected to the surface of the positioning rod.

[0015] The effect achieved by the above components is that by setting the positioning rod, the positioning rod can be located inside the two circular perforated plates to assist in limiting the two circular perforated plates, thereby reducing the shaking that occurs when the two circular perforated plates slide inside the hollow plate.

[0016] Preferably, each of the two spring rods has an auxiliary rod fixedly connected to its end away from the locking block, and the surface of the auxiliary rod is larger than the inner wall of the rectangular tube.

[0017] The effect achieved by the above components is that by setting up an auxiliary rod, the auxiliary rod can provide a point of leverage for personnel, allowing personnel to easily insert and remove the spring rod by manually moving the auxiliary rod.

[0018] Preferably, the interception device includes a rectangular frame, which is fixedly connected to the base. A threaded hole is provided on one side of the rectangular frame, and a bolt is threadedly connected to the inner wall of the threaded hole. A round hole block is slidably connected to the inner wall of the rectangular frame. The surface size and shape of the bolt are adapted to the inner wall size and shape of the round hole block. A frame is fixedly connected to one side of the round hole block. The frame is fitted onto the surface of the protective cover and the base, and an interception net is fixedly connected to the inner wall of the frame.

[0019] The effects achieved by the above components are as follows: By setting up the interception device, the frame is first manually moved, causing the frame to move the interception net, which in turn moves the round hole block. When the round hole block moves to the position where it is fully inserted into the rectangular frame, the frame fits onto the surface of the base and the protective cover, making the inner wall of the round hole block coincide with the inner wall of the threaded hole. At this time, the bolt is manually turned, causing the bolt to turn into the position of the threaded hole and the round hole block, fixing the position of the round hole block and the frame, thus achieving the assembly and fixation of the frame and the base. This allows the frame, together with the interception net, to wrap around the base and the protective cover and intercept external objects. At the same time, in conjunction with the protective cover and the protective base, multiple safety protections are achieved for the transformer inside the base. This reduces the possibility of external objects directly colliding with the protective cover or the base, causing deformation or damage to the protective cover or the base, and preventing the deformed or damaged parts of the protective cover or the base from pressing against the transformer, thus affecting the protection effect of the transformer and improving the safety of the transformer.

[0020] Preferably, one end of the bolt is fixedly connected to a screw block, and the surface of the screw block is provided with multiple anti-slip strips.

[0021] The effect achieved by the above components is that by setting the tightening block, the contact area of ​​the bolt can be increased, allowing personnel to easily rotate the bolt by manually turning the tightening block.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, by setting a limiting device, the part of the wire close to the transformer can be limited and reinforced, reducing the swaying of the wire when affected by strong winds. This prevents the wire end at the connection between the wire and the transformer from swaying along with the wire, causing the wire end at the connection to loosen and fall off under continuous shaking, thus improving the connection stability between the wire and the transformer.

First, the base 1 is installed on an external device or object, then the transformer is installed inside the base 1, and then the wires are connected to the transformer through the wire-passing holes 4. Then, the protective cover 2 is fixed to the base 1 with screws to enclose the transformer, thereby achieving safety protection for the transformer.

[0030] Reference Figure 2 and Figure 3As shown, this embodiment discloses a limiting device 5 including a hollow plate 51. The hollow plate 51 is fixedly connected to the inner wall of the base 1 near the wire hole 4. A through hole 52 is opened on one side of the hollow plate 51, and the inner wall of the through hole 52 penetrates the hollow plate 51. A rectangular hole 58 is opened on one side of the hollow plate 51. Two rectangular cylinders 53 are symmetrically fixedly connected to the inner wall of the hollow plate 51. A locking block 54 is slidably connected to the inner wall of each of the two rectangular cylinders 53. A spring rod 55 is fixedly connected to one side of each of the two locking blocks 54. The surfaces of the two spring rods 55 are slidably connected to the inner walls of the two rectangular cylinders 53, and the other ends of the springs in the two spring rods 55 are fixedly connected to the inner walls of the two rectangular cylinders 53, respectively. Two perforated plates 59 are symmetrically slidably connected to the inner wall of the hollow plate 51. Rubber blocks 510 are fixedly connected to the adjacent sides of the two perforated plates 59. T-shaped plates 512 are fixedly connected to one side of each of the two perforated plates 59. The surfaces of the two T-shaped plates 512 are slidably connected to the inner wall of the rectangular hole 58. Perforated rods 511 are fixedly connected to the sides of the two perforated plates 59 away from the rubber blocks 510. Two locking blocks 54 are located inside the two perforated rods 511, respectively. The size and shape of the locking blocks 54 are adapted to the size and shape of the inner wall of the perforated rods 511. By setting a limiting device 5, the wire is first inserted through the wire hole 4 and passes through the round hole 52, thus allowing the wire to... The part is located inside the hollow plate 51, so that the wire is located between the two rubber blocks 510. At this time, the two T-shaped plates 512 are manually moved, so that the two T-shaped plates 512 drive the two perforated plates 59 to move in opposite directions, so that the two perforated plates 59 drive the two rubber blocks 510 to move in opposite directions, so that the two perforated plates 59 drive the two multi-hole rods 511 to move in opposite directions, so that the two multi-hole rods 511 respectively press the two locking blocks 54 to move, so that the two locking blocks 54 respectively move inward towards the two rectangular cylinders 53. When the two rubber blocks 510 move in opposite directions to the position where they simultaneously press the surface of the wire, under the reaction force of the spring in the spring rod 55, the two spring rods 55 simultaneously drive the two The two locking blocks 54 move towards the multi-hole rod 511. When the two locking blocks 54 move to the corresponding positions inside the holes of the two multi-hole rods 511, the two locking blocks 54 limit the two multi-hole rods 511, and the two multi-hole rods 511 limit the two circular hole plates 59 and the two rubber blocks 510. The two rubber blocks 510 stick together and clamp the wire, thereby limiting and reinforcing the wire. This reduces the swaying of the wire when affected by strong winds, which would cause the wire end at the connection between the wire and the transformer to sway along with the wire. This would cause the wire end at the connection to loosen and fall off under continuous shaking, thus improving the connection stability between the wire and the transformer.

[0031] Reference Figure 2 and Figure 3As shown in the figure, this embodiment discloses that anti-slip pads 513 are fixedly connected to one side of two T-shaped plates 512. The surfaces of the two anti-slip pads 513 are provided with multiple anti-slip protrusions. By setting the anti-slip pads 513, the anti-slip pads 513 can increase the contact friction between the T-shaped plates 512 and the hand, reducing the possibility of hand slippage when manually pushing the T-shaped plates 512. Multiple rubber protrusions 514 are fixedly connected to the adjacent sides of the two rubber blocks 510. The multiple rubber protrusions 514 are arranged at equal distances. By setting the rubber protrusions 514, the rubber protrusions 514 can increase the resistance and adhesion between the rubber blocks 510 and the surface of the wire, further increasing the stability of the rubber blocks 510 in clamping the wire and reducing the possibility of the wire slipping.

[0032] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that a positioning rod 57 is fixedly connected to the inner wall of the hollow plate 51, and the inner walls of the two round hole plates 59 are slidably connected to the surface of the positioning rod 57. By setting the positioning rod 57, the positioning rod 57 can be located inside the two round hole plates 59 to assist in limiting the two round hole plates 59, reducing the shaking of the two round hole plates 59 during the sliding process inside the hollow plate 51. The ends of the two spring rods 55 away from the locking block 54 are fixedly connected to the auxiliary rods 56. The surface of the auxiliary rods 56 is larger than the inner wall of the rectangular tube 53. By setting the auxiliary rods 56, the auxiliary rods 56 can provide a point of force for personnel, so that personnel can easily insert and remove the spring rods 55 by manually moving the auxiliary rods 56.

[0033] Reference Figure 4As shown, this embodiment discloses an interception device 6 including a rectangular frame 61, which is fixedly connected to the base 1. A threaded hole 62 is provided on one side of the rectangular frame 61, and a bolt 63 is threadedly connected to the inner wall of the threaded hole 62. A round hole block 65 is slidably connected to the inner wall of the rectangular frame 61. The surface size and shape of the bolt 63 are adapted to the inner wall size and shape of the round hole block 65. A frame 66 is fixedly connected to one side of the round hole block 65. The frame 66 is fitted onto the surface of the protective cover 2 and the base 1. An interception net 67 is fixedly connected to the inner wall of the frame 66. By setting up the interception device 6, the frame 66 is first manually moved, causing the frame 66 to move the interception net 67, which in turn causes the frame 66 to move the round hole block 65. When the round hole block 65 moves to the position where it is fully inserted into the rectangular frame 61, the frame 66 fits onto the surface of the base 1 and the protective cover 2, so that the inner wall of the round hole block 65 coincides with the inner wall of the threaded hole 62. At this time, the bolt 63 is manually rotated to... The bolt 63 is turned into the threaded hole 62 and the round hole block 65 to fix the position of the round hole block 65 and the frame 66, so as to achieve the assembly and fixation of the frame 66 and the base 1. The frame 66, together with the interception net 67, wraps the base 1 and the protective cover 2 and intercepts external objects. At the same time, with the protection of the base 1, multiple safety protections are achieved for the transformer inside the base 1. This reduces the direct collision between external objects and the protective cover 2 or the base 1, which may cause deformation or damage to the protective cover 2 or the base 1. This could result in the deformed or damaged parts of the protective cover 2 or the base 1 pressing against the transformer, affecting the protection effect of the transformer. This improves the safety of the transformer. One end of the bolt 63 is fixedly connected to the screw block 64. The surface of the screw block 64 is provided with multiple anti-slip strips. By setting the screw block 64, the contact area of ​​the bolt 63 can be increased, so that personnel can easily rotate the bolt 63 by manually rotating the screw block 64.

[0034] Working principle: First, install the base 1 on an external device or object. Then, install the transformer inside the base 1. Insert the wire through the through hole 4 and pass it through the round hole 52 to connect with the transformer inside the base 1. Position the wire partially inside the hollow plate 51, between the two rubber blocks 510. Then, manually move the two T-shaped plates 512, causing them to move the two perforated plates 59 in opposite directions. This, in turn, causes the two rubber blocks 510 to move in opposite directions, which in turn causes the two perforated rods 511 to move in opposite directions. The perforated rods 511 then press against the two locking blocks 54, causing the two locking blocks 54 to move into the two rectangular cylinders 53 respectively. When the two rubber blocks 510 move towards each other and simultaneously press the surface of the wire, the reaction force of the spring in the spring rod 55 causes the two spring rods 55 to simultaneously drive the two locking blocks 54 to move closer to the multi-hole rod 511. When the two locking blocks 54 move to the corresponding positions of the two multi-hole rods 511, the two locking blocks 54 limit the two multi-hole rods 511, and the two multi-hole rods 511 limit the two round hole plates 59 and the two rubber blocks 510, so that the two rubber blocks 510 stick together and clamp the wire, thereby achieving the limiting and reinforcement of the wire. At this time, the protective cover 2 is fixed to the base 1 with screws to enclose the transformer, thereby achieving the safety protection of the transformer.

[0035] At this point, manually move frame 66, causing frame 66 to move interceptor net 67, which in turn moves round hole block 65. When round hole block 65 moves to the position where it is fully inserted into rectangular frame 61, frame 66 fits onto the surface of base 1 and protective cover 2, making the inner wall of round hole block 65 coincide with the inner wall of threaded hole 62. Then, manually rotate screw block 64, causing screw block 64 to rotate bolt 63, which then rotates into the position of threaded hole 62 and round hole block 65, fixing the position of round hole block 65 and frame 66. This achieves the assembly and fixation of frame 66 and base 1, allowing frame 66 to work with interceptor net 67 to wrap base 1 and protective cover 2 and intercept external objects. At the same time, combined with the protection of the base 1, multiple safety protections are achieved for the transformer inside base 1.
