Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically a transformer device used in power generation equipment. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core. It is widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] Transformer installation mainly falls into two categories: one involves mounting the transformer on a utility pole, using the pole as a frame to elevate the transformer off the ground; the other is outdoor installation, where the transformer is directly installed on a reinforced concrete base. With the first method, the base is first fixed between two utility poles, and then a crane is used to hoist the transformer onto the base. However, when the height of the base needs adjustment, the transformer must first be lowered to the ground, the base height adjusted and secured, and finally, the transformer re-hoisted onto the base. This entire adjustment process is cumbersome, time-consuming, and labor-intensive; the transformer is also prone to collisions and damage during repeated hoisting, and there is a risk of accidental falls that could injure workers.

[0004] In order to overcome the above-mentioned problems, there is an urgent need for a transformer device for power generation equipment. Summary of the Invention

[0005] To avoid and overcome the technical problems existing in the prior art, the present invention provides a transformer device for power production equipment. The present invention can adjust the installation height of the transformer according to actual needs, which is quick, convenient, safe and reliable.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A transformer device for power generation equipment includes a transformer body and a support for mounting the transformer body between two utility poles. The support includes locking rings respectively fitted onto the corresponding utility poles. Support rods are arranged on the adjacent side rings of the two locking rings. The front ends of the two support rods are slidably connected to two guide grooves arranged at the bottom of the transformer body. The length directions of the two guide grooves intersect each other to form a V-shaped structure, so that when the transformer body moves up and down in the vertical direction, the distance between the two locking rings is adjusted by the reciprocating sliding movement of the support rods in the guide grooves.

[0008] As a further aspect of the present invention: the guide groove is a T-shaped groove structure with both ends sealed, a guide block is arranged at the front end of the support rod, and the support rod and the guide block constitute a T-shaped rod structure that cooperates with the guide groove.

[0009] As a further embodiment of the present invention: the tail end of the support rod extends toward the corresponding side of the utility pole and bends downward to form an arc-shaped plate structure; the locking ring is coaxially sleeved on the outside of the utility pole; horizontally extending limiting plates are arranged on the side ring surfaces of the two sets of locking rings; a reset spring is arranged between the two limiting plates to push them to move away from each other in opposite directions.

[0010] As a further embodiment of the present invention: A U-shaped groove is formed at the extension end of any limiting plate, and the extension end of the other limiting plate extends into the groove from its opening, pressing the axially horizontally extending return spring against the bottom of the groove. A slide is arranged at the bottom of the support base, and an axial direction parallel to the extension direction of the limiting plate is formed on the slide; the extension ends of both limiting rods are slidably arranged within the limiting holes.

[0011] As a further embodiment of the present invention: the lower surfaces of the two limiting plates are hinged with pull rods, and the cantilever ends of the two pull rods are connected to each other by traction ropes.

[0012] As a further embodiment of the present invention: a sleeve is provided on the outer side of the extension end of the two limiting plates, and the sleeve is fixedly connected to the extension end of either limiting plate.

[0013] As a further embodiment of the present invention: a support base is arranged at the bottom of the transformer body, and two guide grooves are arranged symmetrically on the support base with respect to the symmetrical faces of the two utility poles. The groove openings of the two guide grooves intersect each other and form an inverted V-shaped structure.

[0014] As a further embodiment of the present invention: the locking ring includes an inner retaining ring and an outer retaining ring, both of which are C-shaped. The inner retaining ring and the outer retaining ring together form a clamping cavity arranged coaxially with the utility pole. The inner retaining ring and the outer retaining ring are connected to each other by bolts and nuts at the closing ends.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The support component of this invention can stably fix the transformer body between two utility poles, improving equipment safety and reducing the risk of the transformer body falling during later use. Two symmetrically arranged support rods are slidably installed in two equally symmetrically arranged guide grooves. This symmetrical arrangement ensures synchronized and uniform movement; that is, when the transformer body moves up and down vertically, the two support rods slide synchronously, avoiding the impact of sequential movement on the overall structural center of gravity. This keeps the center of gravity of the entire structure on the same vertical line, reducing transformer body sway and improving the safety of transformer body hoisting. The two guide grooves intersect each other and form a V-shape. Thus, when the transformer body moves vertically upwards, the two support rods will move in close proximity, releasing the outward pushing force on the corresponding utility poles, thereby causing the locking ring to move upwards synchronously with the transformer body. Furthermore, because the utility pole has a conical rod-like structure, the distance between the two locking rings increases as the pole rises and decreases as it descends. Therefore, as the transformer body moves upward, the distance between the two locking rings gradually increases after the pushing action is released. When the transformer body reaches the predetermined position, the locking rings can be locked onto the utility pole, thus securing the transformer body. This V-shaped guide groove allows the transformer body to fall instantly if it accidentally detaches from the crane hook. However, the support rods move with a lag, and the transformer body, under the action of the guide groove, pushes the two support rods outward, causing the inner side of the locking rings to press against the utility pole, preventing the transformer body from falling or slowing its descent, thus reducing damage to the transformer.

[0017] 2. As the transformer body descends vertically, a return spring is compressed between the two limit plates, ensuring that the inner side of the locking ring contacts the utility pole during the upward movement of the locking ring, further enhancing the fall protection function. Pulling down the lever hinged to the corresponding limit plate with a traction rope allows for adjustment of the distance between the two locking rings during descent, improving the smoothness of the transformer body's descent.

[0018] 3. The traction rope of the present invention can be manually pulled downwards, which allows for adjustments at any time according to the actual situation; alternatively, a counterweight can be used, adjusting the mass of the counterweight to the ratio of the return spring, so that the locking ring remains coaxial with the power line during downward movement, thus preventing contact with the power pole and greatly improving the smoothness of the transformer body's downward movement.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-5 The present invention is mainly composed of a transformer body 10 and a support part 20.

[0030] The transformer body 10 is usually mounted on the symmetrical plane of two utility poles, so that the force on each utility pole is the same, avoiding the fact that one utility pole is under too much force and sinks, which would eventually cause the utility pole to tilt and collapse.

[0031] A support base 11 is arranged at the bottom of the transformer body 10. On the support base 11, two T-shaped limiting grooves with closed ends are arranged symmetrically with respect to the two poles. The length directions of the two limiting grooves are located on the same vertical plane and intersect each other to form a V-shaped structure.

[0032] The support part 20 includes a locking ring 24 that fits onto the outside of the utility pole. The locking ring 24 includes an inner retaining ring 241 and an outer retaining ring 242, both of which are C-shaped. The inner retaining ring 241 and the outer retaining ring 242 form a clamping cavity coaxially arranged with the utility pole. The inner retaining ring 241 and the outer retaining ring 242 are connected to each other by bolts and nuts at the closing ends. During the movement of the locking ring 24, the locking ring 24 is in a loose state; when the position of the transformer body 10 is determined, the locking ring 24 can be locked.

[0033] The support part 20 also includes two support rods 21 arranged symmetrically with the two utility poles. A guide block 211 is arranged at the front end of the support rod 21 to form a T-shaped rod structure that slides with the guide groove 12. The guide block 211 is slidably arranged in the guide groove 12.

[0034] The tail end of the support rod 21 extends toward the corresponding side of the utility pole and bends downwards to form an arc-shaped plate structure. The tail end of the support rod 21 is fixedly connected to the inner locking ring of the locking ring 24.

[0035] Two sets of locking rings 24 have horizontally extending limiting plates 22 arranged on their adjacent side ring surfaces. One limiting plate 22 has a U-shaped groove 221 at its extended end, and the other limiting plate 22 extends into the groove 221 from its opening, pressing the axially horizontally extending return spring 23 against the bottom of the groove. A sleeve 13 is fitted on the outside of the extended ends of the two limiting plates 22, and the sleeve 13 is fixedly connected to the extended end of either limiting plate 22. This encloses the extended ends of the two limiting plates 22, reducing external interference.

[0036] Both limit plates 22 have tie rods 27 hinged to their lower surfaces, and the cantilever ends of the two tie rods 27 are connected to each other by traction ropes 28.

[0037] The support part 20 of this invention can stably fix the transformer body 10 between two utility poles, improving the safety of the equipment and reducing the risk of the transformer body 10 falling during later use. Two symmetrically arranged support rods 21 are slidably installed in two equally symmetrically arranged guide grooves 12. This symmetrical arrangement ensures synchronized and uniform movement; that is, when the transformer body moves up and down along the vertical direction, the two support rods 21 slide synchronously, avoiding the impact of sequential movement on the center of gravity of the entire structure. This keeps the center of gravity of the entire structure on the same vertical line, reducing the swaying of the transformer body 10 and improving the safety of hoisting the transformer body 10. The two guide grooves 12 intersect each other and form a V-shaped structure. When the transformer body moves vertically upward, the two support rods 21 will move in close proximity, thereby releasing the outward pushing state on the corresponding utility pole, and thus driving the locking ring 24 to move upward synchronously with the transformer body 10. Since the utility pole is a conical rod-shaped structure, the distance between the two locking rings 24 will be larger as it goes up, and smaller as it goes down. Therefore, when the transformer body moves upward, the distance between the two locking rings 24 gradually increases after the pushing state is released. When the transformer body rises to the predetermined position, the locking ring 24 can be locked onto the utility pole, thereby fixing the transformer body 10. By using such a V-shaped guide groove 12, when the transformer body accidentally detaches from the crane hook, the transformer body falls instantly, but at this time the movement of the support rod 21 is delayed. Under the action of the guide groove 12, the transformer body 10 pushes the two support rods 21 outward so that the inner side of the locking ring 24 is pressed against the utility pole, thus preventing the transformer body 10 from falling, or slowing down the falling speed of the transformer body 10 and reducing the damage to the transformer.

[0038] As the transformer body descends vertically, a limiting plate 22 is installed between the two locking rings 24 to facilitate adjustment of the distance between them. A return spring 23 is compressed between the two limiting plates 22, ensuring that the inner surface of the locking rings 24 contacts the utility pole during the upward movement of the locking rings 24, further enhancing the fall protection function. A traction rope 28 is used to pull down the pull rod 27 hinged to the corresponding limiting plate 22, allowing for adjustment of the distance between the two locking rings 24 during descent and improving the smoothness of the transformer body's descent.

[0039] The traction rope 28 can be manually pulled downwards, allowing for adjustments as needed; alternatively, a counterweight can be used, adjusting its mass relative to the return spring 23 to ensure the locking ring 24 remains coaxial with the power line during downward movement, preventing contact with the power pole and significantly improving the smoothness of the transformer body 10's descent.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
