Description
Technical Field
[0001] The invention relates to the technical field of transformers, and in particular to a transformer with a noise reduction function. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Transformers are widely used in power systems, mainly for stepping up and down voltage. The electric energy generated by the generator is stepped up by a step-up transformer and then sent to the power grid to reduce energy loss during transmission.
[0003] The transformer generates an alternating magnetic field during operation. Magnetostriction causes the core to vibrate periodically, thus generating noise. In addition to the vibration caused by magnetostriction, the vibration of the core may also come from the electromagnetic attraction between the joints and laminations.
[0004] When the transformer is in a place with a large number of people, in order to avoid the transformer generating loud noise during use and affecting people's rest, a noise reduction shell is usually installed on its outer surface to play a protective role. However, in the prior art, noise reduction is only achieved through sound insulation measures such as sound insulation cotton. When the transformer is working, it still vibrates. While the transformer is running, the transformer itself vibrates and collides with the noise reduction shell. The collision between them causes noise to be generated. The noise is weakened under the noise reduction shell and propagates outward, but it still generates noise. In addition, because the transformer body vibrates and collides with the noise reduction shell, the transformer is damaged and cannot operate normally, or the shell is damaged, making it impossible to effectively reduce noise. Therefore, we propose a transformer with noise reduction function. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention provides a transformer with a noise reduction function, which solves the problem that the transformer vibrates and collides with equipment, causing noise, and even the transformer or casing is damaged due to vibration and collision.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A transformer with noise reduction function, comprising a transformer body, a protective shell, a plurality of vibration reduction units and a plurality of adjustment units, a plurality of sealing doors are rotatably connected to the inner wall of the protective shell, the vibration reduction units are located at the upper and lower ends of the transformer body, and the adjustment units are connected to the vibration reduction units. The vibration reduction unit includes a mounting seat fixedly mounted on the transformer body, a support seat is arranged below the mounting seat, and a plurality of springs are fixedly connected between the mounting seat and the support seat; The adjusting unit comprises a plurality of push rods rotatably connected to the support seat, and one end of the push rod away from the support seat is slidably connected to the sliding seat; The bottom end surface of the sliding seat is fixedly connected with a contact seat, the bottom end surface of the contact seat at the bottom is slidably connected with a slide rail, and the slide rail is fixedly connected to the inner wall of the protective shell.
[0007] Preferably, a plurality of support columns are fixedly connected to the top end surface of the transformer body, the top end surfaces of the support columns are fixedly connected to the upper mounting seats, and the upper mounting seats are connected to the transformer body via the support columns.
[0008] Preferably, a plurality of dampers are fixedly connected between the mounting seat and the support seat, a guide rod is slidably connected to the inner wall of the mounting seat, the guide rod is inserted into the interior of the spring, and the end of the guide rod is fixedly connected to the contact seat.
[0009] Preferably, a plurality of rotating seats are fixedly connected to the bottom of the support seat, the rotating seat is rotatably connected to the push rod, one end of the push rod away from the rotating seat is rotatably connected to a nut seat, and the nut seat is slidably connected to the inner wall of the sliding seat.
[0010] Preferably, a bidirectional screw rod is rotatably connected to the inner wall of the sliding seat, and the bidirectional screw rod is threadedly connected to two corresponding nut seats.
[0011] Preferably, one end of the bidirectional screw rod outside the sliding seat is sleeved with a pulley, and the outer peripheral walls of the multiple pulleys are connected to the transmission belt, and the end of one of the bidirectional screw rods is connected to the driving mechanism.
[0012] Preferably, a support unit is provided on the side of the contact seat at the bottom, and the support unit includes a plurality of fixing seats fixedly connected to the contact seat.
[0013] Preferably, a threaded rod is slidably connected to the inner wall of the fixing seat, a limiting seat is fixedly connected to the bottom end surface of the threaded rod, an adjusting nut is threadedly connected to the outer peripheral wall of the threaded rod, and the adjusting nut is rotatably connected to the fixing seat.
[0014] The present invention discloses a transformer with a noise reduction function, which has the following beneficial effects: The transformer with noise reduction function, when the transformer main body is running, the transformer main body vibrates, and the vibration of the transformer main body drives the mounting seat to move toward the supporting seat, so that the mounting seat compresses the spring, and at the same time, with the cooperation of the damper, the transformer main body is damped, so that when the transformer is running, its own vibration is weakened, and the noise generation is effectively reduced. At the same time, with the action of the protective shell, the noise is soundproofed, the noise reduction effect is improved, and the transformer is protected at the same time. The transformer is protected, and the collision of the transformer main body with the protective shell is effectively avoided, so that the protective shell and the transformer are used normally, and the noise generation is further prevented, so that the transformer is not affected by the outside world when in use.
[0015] The transformer with noise reduction function has different sizes when different transformers are used, and the vibrations of the transformers themselves are different. When the vibration of the transformer body is too large, the spring fluctuates greatly, affecting the stability of the transformer body. At this time, the pulley is driven to rotate by rotating the bidirectional lead screw, so that the transmission belt rotates. Under the action of the transmission belt, the two bidirectional lead screws rotate at the same time, and then the two nut seats threadedly connected to the bidirectional lead screws move in opposite directions, driving the push rod to rotate, and pushing the support seat to move. At this time, the support seat compresses the spring, so that the initial energy storage of the spring is larger. Under the limitation of the spring, the vibration of the transformer bodies of different sizes is limited, and its own vibration is weakened, thereby reducing the generation of noise, so that it cooperates with the protective shell to ensure the noise reduction effect, and has less impact on the outside world.
[0016] When installing and disassembling the transformer body of the transformer with the noise reduction function, the support column and the mounting seat are first disassembled, and then the two bidirectional lead screws are rotated at the same time, so that the two nut seats threadedly connected with the bidirectional lead screws move in opposite directions, and the support seat is pushed to move, so that the upper part of the transformer body is separated from the corresponding mounting seat, and then the bolts between the transformer body and the lower mounting seat are removed, so that the transformer body can be stably disassembled, and the position of the transformer body is limited by installing the transformer body on the mounting seat, and the two support seats are adjusted to move so that the two mounting seats limit the transformer body, and then it is fixed by bolts, so as to ensure the stability of the transformer body and its convenient and accurate installation.

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] The embodiment of the present application provides a transformer with a noise reduction function, which solves the problem that the transformer vibrates and collides with the equipment, causing noise, and even the transformer or the casing is damaged due to vibration and collision. When the transformer main body 1 is running, the transformer main body 1 vibrates due to operation. At this time, the vibration of the transformer main body 1 itself drives the mounting seat 401 to swing toward the support seat 402, so that the mounting seat 401 moves to compress the spring 403. At the same time, with the cooperation of the damper 404, the transformer main body 1 is damped, so that the transformer main body 1 does not directly contact the protective shell 2, thereby avoiding the generation of noise due to vibration and impact. At the same time, the transformer main body 1 is prevented from colliding with the protective shell 2, and the transformer main body 1 and the protective shell 2 are protected.
[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] An embodiment of the invention discloses a transformer with a noise reduction function.
[0024] According to the attached Figure 1-7As shown, it includes a transformer body 1, a protective shell 2, a plurality of vibration reduction units 4 and a plurality of adjustment units 6. A plurality of sealing doors 201 are rotatably connected to the inner wall of the protective shell 2. The sealing doors 201 are opened and closed to facilitate protection or maintenance of the transformer body 1. The transformer body 1 can be directly observed by opening the sealing door 201. When the sealing door 201 is closed, the transformer body 1 is sealed to achieve a noise reduction effect. The vibration reduction units 4 are located at the upper and lower ends of the transformer body 1. The adjustment units 6 are connected to the vibration reduction units 4. The vibration reduction unit 4 includes a mounting seat 401 fixedly mounted on the transformer body 1, a support seat 402 is arranged below the mounting seat 401, and a plurality of springs 403 are fixedly connected between the mounting seat 401 and the support seat 402. When the transformer body 1 is running, the transformer body 1 vibrates, and the vibration of the transformer body 1 drives the mounting seat 401 to move toward the support seat 402, so that the mounting seat 401 compresses the spring 403, and at the same time, with the cooperation of the damper 404, the transformer body 1 is damped to avoid the generation of noise, and at the same time, the transformer body 1 is effectively prevented from colliding with the protective shell 2, and the transformer body 1 and the protective shell 2 are protected; The adjusting unit 6 includes a plurality of push rods 604 rotatably connected to the support seat 402. One end of the push rod 604 away from the support seat 402 is slidably connected to the sliding seat 601. When the vibration of the transformer body 1 is too large, the spring 403 fluctuates greatly, affecting the stability of the transformer body 1. At this time, the pulley is driven to rotate by rotating the bidirectional screw rod 602, so that the transmission belt 606 rotates. Under the action of the transmission belt 606, the two bidirectional screw rods 602 rotate at the same time, so that the two nut seats 603 threadedly connected to the bidirectional screw rod 602 move in the opposite direction, driving the push rod 604 to rotate, and pushing the support seat 402 to move. At this time, the support seat 402 compresses the spring 403, so that the initial energy storage of the spring 403 is large, thereby limiting the vibration of the transformer body 1, effectively protecting the transformer body 1 and reducing noise; The bottom end surface of the sliding seat 601 is fixedly connected with a contact seat 5, and the bottom end surface of the contact seat 5 at the bottom is slidably connected with a slide rail 8, and the slide rail 8 is fixedly connected to the inner wall of the protective shell 2. By pulling the transformer main body 1 to move, the transformer main body 1 drives the vibration reduction unit 4 and the adjustment unit 6 to move. At this time, the guide rod 501 moves to drive the contact seat 5 to slide on the slide rail 8, so that the transformer main body 1 is outside the protective shell 2, which is convenient for maintenance of the transformer main body 1.
[0025] When installing and disassembling the transformer body 1 at this time, first disassemble the support column 3 and the mounting seat 401, and then rotate the two bidirectional screw rods 602 at the same time, so that the two nut seats 603 threadedly connected with the bidirectional screw rods 602 move in opposite directions, drive the push rod 604 to rotate, and push the support seat 402 to move. When the support seat 402 moves, the mounting seat 401 moves, so that the upper part of the transformer body 1 is separated from the corresponding mounting seat 401, and then the transformer body 1 can be stably disassembled by removing the bolts between the transformer body 1 and the lower mounting seat 401; By installing the transformer body 1 on the mounting seat 1, the position of the transformer body 1 is limited, and by adjusting the movement of the two support seats 402, the two mounting seats 401 limit the transformer body 1, and then fixing it with bolts, the stability of the transformer body 1 and its convenient and accurate installation can be ensured.
[0026] A plurality of support columns 3 are fixedly connected to the top end surface of the transformer body 1, and the top end surface of the support column 3 is fixedly connected to the mounting seat 401 above. The mounting seat 401 above is connected to the transformer body 1 through the support column 3, and the transformer body 1 is connected to the vibration reduction unit 4 and the adjustment unit 6 above through the support column 3. The vibration reduction unit 4 and the adjustment unit 6 on both sides of the transformer body 1 are used to reduce vibration and noise of the transformer body 1.
[0027] A plurality of dampers 404 are fixedly connected between the mounting seat 401 and the support seat 402. A guide rod 501 is slidably connected to the inner wall of the mounting seat 401. The guide rod 501 is inserted into the inside of the spring 403. The end of the guide rod 501 is fixedly connected to the contact seat 5. Under the action of the damper 404, the mounting seat 401 moves to dampen the transformer body 1, effectively avoiding the huge vibration of the transformer body 1, which leads to the instability of the transformer body 1. When the transformer body 1 vibrates, the mounting seat 401 slides along the guide rod 501. Under the action of the guide rod 501, the sliding path of the mounting seat 401 is stabilized, thereby making the transformer body 1 more stable. At the same time, the guide rod 501 is used to limit the spring 403 to ensure the stability of the spring 403.
[0028] The bottom of the support seat 402 is fixedly connected with a plurality of rotating seats 605 , which are rotatably connected to the push rod 604 , and one end of the push rod 604 away from the rotating seat 605 is rotatably connected with a nut seat 603 , which is slidably connected to the inner wall of the sliding seat 601 .
[0029] A bidirectional screw rod 602 is rotatably connected to the inner wall of the sliding seat 601, and the bidirectional screw rod 602 is threadedly connected to the corresponding two nut seats 603. When the bidirectional screw rod 602 rotates, the two nut seats 603 threadedly connected to the bidirectional screw rod 602 move in opposite directions, driving the push rod 604 to rotate. At this time, the two push rods 604 rotate in opposite directions, pushing the rotating seat 605 to move, driving the support seat 402 to move upward, and the spring 403 is further compressed under the movement of the support seat 402, so that the initial energy storage of the spring 403 is larger, thereby limiting the vibration of the transformer body 1, effectively protecting the transformer body 1 and reducing noise.
[0030] One end of the bidirectional screw rod 602 outside the sliding seat 601 is sleeved with a pulley, and the outer peripheral walls of the multiple pulleys are connected to the transmission belt 606. The end of one of the bidirectional screw rods 602 is connected to a driving mechanism, and the pulley is driven to rotate by rotating the bidirectional screw rod 602. The rotation of the pulley causes multiple transmission belts 606 to rotate, and under the action of the transmission belt 606, the two bidirectional screw rods 602 rotate at the same time.
[0031] A support unit 7 is provided on the side of the contact seat 5 below. The support unit 7 includes a plurality of fixed seats 701 fixedly connected to the contact seat 5. When the transformer body 1 is moved by pulling, the guide rod 501 moves to drive the contact seat 5 to slide on the slide rail 8, so that the transformer body 1 is outside the protective shell 2.
[0032] A threaded rod 702 is slidably connected to the inner wall of the fixed seat 701, and a limiting seat 703 is fixedly connected to the bottom end face of the threaded rod 702. An adjusting nut 704 is threadedly connected to the outer peripheral wall of the threaded rod 702. The adjusting nut 704 is rotatably connected to the fixed seat 701. By rotating the adjusting nut 704, the threaded rod 702 is driven to rotate. At this time, the threaded rod 702 slides downward along the inner wall of the fixed seat 701 until the limiting seat 703 contacts the ground. When multiple limiting seats 703 are adjusted to contact the ground, the transformer body 1 is relatively stable under the support of the limiting seats 703, which is convenient for the maintenance of the transformer body 1. When the inspection is completed, the limiting seat 703 is fitted with the fixing seat 701 by rotating the adjusting nut 704 in the opposite direction, so that the contact seat 5 can slide along the slide rail 8, driving the transformer body 1 to be inside the protective shell 2. At this time, the adjusting nut 704 is rotated again to perform the same movement as above, so that the limiting seat 703 is fitted with the bottom end surface of the protective shell 2, and the position of the contact seat 5 is limited to ensure the stability of the transformer body 1.
[0033] When the transformer body 1 is in use, the transformer body 1 is installed in the protective shell 2, and the sealing door 201 is closed at this time. The transformer body 1 is protected and sealed by the protective shell 2 and the sealing door 201, and the noise of the transformer body 1 is reduced, and the propagation of noise is reduced to achieve the noise reduction effect. By opening the sealing door 201, the transformer body 1 can be directly observed and tested. When the transformer body 1 is running, the transformer body 1 generates vibrations due to the operation. At this time, the vibration of the transformer body 1 itself drives the mounting seat 401 to shake toward the support seat 402, so that the mounting seat 401 moves to compress the spring 403. At the same time, with the cooperation of the damper 404, the transformer body 1 is damped, so that the transformer body 1 does not directly contact the protective shell 2, thereby avoiding the generation of noise due to vibration and impact, and avoiding the transformer body 1 from colliding with the protective shell 2, thereby protecting the transformer body 1 and the protective shell 2; At the same time, under the action of the damper 404, when the transformer body 1 is in operation, the mounting seat 401 is used to reduce vibration and buffer the transformer body 1, thereby effectively preventing the transformer body 1 from vibrating violently and causing instability of the transformer body 1; When the transformer body 1 vibrates, the transformer body 1 drives the mounting seat 401 to slide along the guide rod 501. Under the action of the guide rod 501, the sliding path of the mounting seat 401 is stabilized, thereby making the transformer body 1 relatively stable. At the same time, the spring 403 is limited by the guide rod 501 to ensure the stability of the spring 403. When the vibration of the transformer body 1 is too large, or when different types of transformer bodies 1 are subjected to vibration and noise reduction, the initial energy storage of the spring 403 needs to be adjusted to avoid large fluctuations of the spring 403 that affect the stability of the transformer body 1; The pulley is driven to rotate by rotating the bidirectional screw rod 602, and the multiple transmission belts 606 are rotated under the rotation of the pulley. Under the action of the transmission belt 606, the two bidirectional screw rods 602 are rotated at the same time; At this time, the two nut seats 603 threadedly connected with the bidirectional screw rod 602 move in the opposite direction, driving the push rod 604 to rotate. At this time, the two push rods 604 rotate in the opposite direction, driving the rotating seat 605 to move, driving the support seat 402 to move upward, and the spring 403 is further compressed under the movement of the support seat 402, so that the initial energy storage of the spring 403 is larger; When the transformer body 1 is in operation, the reaction force of the spring 403 on the transformer body 1 increases, thereby limiting the vibration amplitude of the transformer body 1, effectively protecting the transformer body 1 and reducing noise, thereby effectively reducing noise; When the transformer body 1 needs to be inspected, the transformer body 1 needs to be pulled out to the outside of the protective shell 2 to facilitate the inspection or disassembly of the transformer body 1. At this time, the transformer body 1 is pulled outward, and the vibration reduction unit 4 and the adjustment unit 6 connected to the transformer body 1 move outward accordingly. At this time, the contact seat 5 fixedly connected to the vibration reduction unit 4 and the adjustment unit 6 moves, so that the contact seat 5 slides on the slide rail 8 until the transformer body 1 is outside the protective shell 2; Then, by rotating the adjusting nut 704, the threaded rod 702 is driven to rotate, and at this time, the threaded rod 702 slides downward along the inner wall of the fixing seat 701 until the limiting seat 703 contacts the ground. When multiple limiting seats 703 are adjusted to contact the ground, the transformer body 1 is relatively stable under the support of the limiting seats 703, which is convenient for maintenance or disassembly of the transformer body 1. When the inspection is completed, the adjusting nut 704 is rotated in the reverse direction to make the limiting seat 703 fit with the fixing seat 701. At this time, the limiting seat 703 is separated from the ground, and the transformer body 1 can be pushed to move inside the protective shell 2. The above-mentioned reverse movement is performed to make the contact seat 5 slide along the slide rail 8 until the transformer body 1 is driven to the specified position inside the protective shell 2. At this time, by rotating the adjusting nut 704, the same movement as mentioned above is performed to drive the limiting seat 703 to move downward relative to the contact seat 5 until the limiting seat 703 contacts and squeezes the bottom end surface of the protective shell 2. Under the action of the limiting seat 703, the position of the contact seat 5 is limited to ensure the stability of the transformer body 1, so that the transformer body 1 can operate normally without shaking left and right.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
