Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to an anti-collision transformer. Background Art
[0002] The utility model relates to the field of transformers, and in particular to the design of an anti-collision transformer. As an important device in the power system, the transformer plays a vital role in the power transmission and distribution links. However, with the diversification of transformer application scenarios, especially in outdoor environments and high-risk areas, transformers are often subjected to impacts and collisions from the external environment. The action of these external forces may cause damage to the transformer body or its structural components, thereby affecting the stable operation of the transformer.
[0003] Some existing transformers may be equipped with protective structures, such as casings and guardrails, but these solutions have obvious shortcomings. For example, the existing transformer protection structure is usually just a simple hard protection, which cannot effectively absorb and disperse external force impact, resulting in the transformer still being seriously damaged under strong collision. In particular, when external force directly acts on the heat dissipation fins of the transformer, it is very easy to cause the fins to deform or damage, thereby affecting the heat dissipation performance of the transformer, causing the equipment to overheat, and in severe cases, it may even cause equipment failure.
[0004] To this end, we propose an anti-collision transformer. Utility Model Content
[0005] The utility model mainly solves the above-mentioned existing technical problems and provides an anti-collision transformer.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-collision transformer, including a transformer body, a row of heat dissipation fins are horizontally arranged on each side of the four sides of the transformer body, and a protective sleeve is movably sleeved on the outer side of each individual heat dissipation fin, and a reset rod assembly that automatically resets and rebounds when subjected to lateral force is arranged between each protective sleeve for maintenance of the corresponding heat dissipation fin.
[0007] Preferably, each of the reset rod assemblies includes a spring rod vertically distributed on the outside of the corresponding heat dissipation fin, a damper is provided between one end of each spring rod and the heat dissipation fin, and the other end of the spring rod is connected to a clamping block, each protective sleeve includes a protective sleeve shell sleeved on the outside of the heat dissipation fin, and the inner bottom surface of each protective sleeve shell is provided with a docking ring block for clamping with the corresponding clamping block.
[0008] Preferably, each of the clamping blocks is a cross-shaped elastic block, and each docking ring block is provided with a cross groove matched with the clamping block.
[0009] Preferably, a limiting ring is sleeved on the outer side of each heat dissipating fin close to the transformer body.
[0010] Preferably, two groups of connecting rods are arranged on the outside of each transformer body, and the two connecting rods weld the upper and lower outermost ends of a row of protective shells on the outside of the transformer body.
[0011] Preferably, a base platform with a height of at least ten centimeters is installed at the bottom of the transformer body.
[0012] Beneficial Effects
[0013] The utility model provides an anti-collision transformer, which has the following beneficial effects:
[0014] 1. The anti-collision transformer has a buffering and anti-collision effect. Through the cooperation of the protective shell, spring rod, damper and clamping block, when external force acts, the spring rod compresses to absorb the impact force, and the damper slowly releases the pressure, avoiding the external force directly acting on the heat dissipation fins or the transformer body, greatly improving the anti-collision protection ability. At the same time, the spring rod has an automatic reset function to ensure that the protective shell can be restored to its original position in time after a collision to maintain the stability of the system.
[0015] 2. The anti-collision transformer has an external force dispersion effect. By welding the heat dissipation fins and protective sleeves around the transformer body and two connecting rods together, when one side is subjected to external force, the external force on that side can be dispersed to the protective structure of the entire side, reducing the force on a single heat dissipation fin or protective sleeve, further improving the overall anti-collision performance, and avoiding damage caused by local excessive force.
[0016] 3. The anti-collision transformer has a stable connection and easy maintenance effect. The design of the cross-shaped clamping block and the docking ring block ensures a firm connection between the protective shell and the heat dissipation fins to avoid loosening during long-term use or frequent collisions. In addition, this clamping method is easy to disassemble, maintain and replace, which improves the maintenance convenience and service life of the system.
[0017] 4. The anti-collision transformer has a limit protection effect. By setting a limit ring on the side of the heat sink fin close to the transformer body, the protective cover is prevented from excessive movement and direct contact with the transformer body when sliding, thereby avoiding affecting the heat dissipation function of the heat sink fin. This design ensures that while providing protection, it will not have a negative impact on the heat dissipation performance of the transformer.
[0018] 5. The anti-collision transformer has moisture-proof and supporting effects. The base isolates the transformer body from the ground, preventing the transformer from directly contacting the wet ground, thereby effectively avoiding rust or damage caused by moisture and extending the service life of the transformer. In addition, the base also plays a role in improving the overall stability of the transformer, preventing the transformer from tilting or becoming unstable due to uneven ground or external impact.

[0028] 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 in 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.
[0029] Embodiment: An anti-collision transformer, such as Figure 1 - Figure 5As shown; it includes a transformer body 1, and a row of heat dissipation fins 2 are horizontally arranged on each side of the four sides of the transformer body 1, and a protective sleeve is movably sleeved on the outer side of each individual heat dissipation fin 2, and a reset rod assembly that automatically resets and rebounds when subjected to lateral force is arranged between each protective sleeve and the corresponding heat dissipation fin 2.
[0030] Each of the reset rod assemblies includes a spring rod 4 vertically distributed on the outside of the corresponding heat dissipation fin 2, a damper 401 is connected between one end of each spring rod 4 and the heat dissipation fin 2, and the other end of the spring rod 4 is connected to a clamping block 402, each protective sleeve includes a protective sleeve shell 3 sleeved on the outside of the heat dissipation fin 2, and the inner bottom surface of each protective sleeve shell 3 is provided with a docking ring block 403 for clamping with the corresponding clamping block 402.
[0031] Each of the clamping blocks 402 in the present technical solution is a cross-shaped elastic block, and each of the docking ring blocks 403 is provided with a cross groove matched with the clamping block 402 .
[0032] A limiting ring 201 is sleeved on the outer side of each of the heat dissipating fins 2 close to the transformer body 1. By sleeved on the outer side of the heat dissipating fins 2 close to the transformer body 1, when the protective sleeve 3 slides back and forth on the heat dissipating fins 2, a limiting effect is exerted on the sliding protective sleeve 3, preventing the protective sleeve 3 from abutting against the corresponding outer side of the transformer body 1 along the outer side of the heat dissipating fins 2, and exerting a limiting effect on the protective sleeve 3 slidably sleeved on the heat dissipating fins 2.
[0033] Two groups of connecting rods 5 are arranged on the outside of each transformer body 1. The two connecting rods 5 weld the upper and lower outermost ends of a row of protective shells 3 on the outside of the transformer body 1. The protective shells on each side of the four outer sides of the transformer body 1 are welded and fixed by two connecting rods 5. All the heat dissipating fins 2 and the protective shells 3 on each side around the transformer body 1 form a whole. When there is external pressure or collision contact with the protective shells 3, all the protective shells 3 on one side of the transformer body 1, the reset rod assembly and the connecting rods 5 cooperate with each other to disperse the external force applied to all the protective shells 3 on the same outer side of the transformer body 1, which has the effect of diverting and buffering the pressure applied from the outside, thereby improving the anti-collision ability of the transformer body 1.
[0034] A base 101 with a height of at least ten centimeters is installed at the bottom of the transformer body 1 to prevent the transformer body 1 from contacting the ground, thereby achieving a supporting and moisture-proof effect.
[0035] The working principle of this utility model:
[0036] 1. Protection effect of heat sink fins and protective sleeve The protective sleeve 3 on the outside of the heat sink fin 2 provides physical protection for it, preventing external pressure or collision from directly acting on the heat sink fin. At the same time, the protective sleeve can slide to adapt to the direction of external impact.
[0037] Reset rod assembly: The reset rod assembly includes a spring rod 4 and a damper 401. The cooperation between the spring rod and the damper realizes the automatic reset and buffering function after the external force is applied. After the external force is applied, the spring rod is compressed and slowly rebounds through the damper, dispersing the external force and reducing the direct transmission of the impact.
[0038] 2. Stable connection between the clamping block and the docking ring block
[0039] Snap-on block 402: The cross-shaped elastic snap-on block is matched with the cross groove on the corresponding docking ring block 403 to ensure that the protective shell and the heat dissipation fins can be firmly connected.
[0040] Docking ring block 403: The docking ring block and the clamping block are clamped with each other, which ensures the stability of the protective structure when an external force acts, and prevents the protective shell from loosening or shifting due to vibration or small collision.
[0041] 3. Limiting function of the limiting ring
[0042] Limiting ring 201: The limiting ring is installed on the side of the heat sink fin close to the transformer body, which can effectively prevent the protective sleeve from sliding too much along the outer side of the heat sink fin, ensuring that the protective sleeve can slide freely within a certain range without affecting the heat dissipation of the transformer body or the stability of other structures.
[0043] Prevent excessive sliding: The limit ring effectively limits the sliding range of the protective cover, avoids direct contact between the protective cover and the transformer body, and ensures that the protective cover can move flexibly and uncontrollably on the transformer.
[0044] Ensure heat dissipation effect: The limit ring prevents the protective shell from being too close to the transformer body, ensuring the contact area between the heat dissipation fins and the outside air, maintaining good heat dissipation performance.
[0045] 4. Structural stability of the connecting rod
[0046] Connecting rod 5: The protective casing is firmly connected to the transformer body through two connecting rods. The connecting rod 5 is welded to the upper and lower ends of the protective casing respectively to form a stable protective frame.
[0047] Welding fixation: The connecting rod fixes the protective casing to the outside of the transformer body by welding, making the entire protective structure more solid and unified.
[0048] Improved integrity: The connecting rod connects the protective shell and heat sink fins around the transformer into one, which improves the impact resistance of the entire structure. When external force acts on one side, the entire protection system can bear the pressure together.
[0049] External force diversion: The connecting rod and the protective shell work together. When a certain part is subjected to external force, the external force can be diverted to other protective shells to reduce the stress pressure on a single part.
[0050] 5. Moisture-proof and supporting effect of the base
[0051] Base 101: The base isolates the transformer body from the ground. The base height is at least 10 cm, which can effectively prevent the transformer from rusting or being damaged due to the influence of wet ground.
[0052] Moisture-proof and rust-proof: The base can effectively prevent the transformer body from directly contacting the wet ground and extend the service life of the transformer.
[0053] Improve stability: The base platform plays a supporting role, improving the overall stability of the transformer and preventing the transformer from tipping over or becoming unstable due to uneven ground or other external factors.
[0054] Optimized heat dissipation performance: Although the protective cover covers the heat dissipation fins, the design of the limiting ring and the sliding protective cover prevents the heat dissipation fins from being completely enclosed and still able to have good contact with the air, ensuring that the heat dissipation performance of the transformer will not be significantly affected.
[0055] Modular design: The design of the clamping block and the docking ring block makes the protection structure have certain modular characteristics. It can be easily disassembled, maintained and replaced according to actual needs without the need to replace the entire transformer protection system.
[0056] The design of the anti-collision transformer fully considers the needs of protection, buffering, heat dissipation and other aspects. It mainly achieves the effects of impact resistance, external force dispersion, automatic reset, protection of heat dissipation fins, and improvement of the overall protection ability of the transformer through the cooperation of multiple structures such as the protective shell, reset rod assembly, connecting rod, and clamping block. At the same time, the design of the limit ring ensures the stability of the protection structure during sliding, and the base platform further improves the moisture-proof performance of the equipment.
