Description

Technical Field

[0001] The utility model relates to the field of transformer heat dissipation protection, in particular to a transformer heat dissipation protection device. Background Art

[0002] Transformer cooling devices usually refer to various devices and measures used to protect the transformer from overheating during operation. These devices are designed to ensure that the transformer can dissipate heat effectively to avoid damage to the equipment or reduce the life of the equipment due to overheating. The radiator will be directly connected to the transformer casing, but there is a lack of protection for the radiator itself. The radiator is easily damaged by long-term exposure to the air, and directly shielding and protecting the radiator will affect the maintenance work of the radiator.

[0003] Therefore, a transformer heat dissipation protection device is now developed to address the above problems. Utility Model Content

[0006] Furthermore, the ventilation protection mechanism includes a protection plate, a plurality of the protection plates are rotatably connected to the left and right sides of the first installation frame, a worm gear is connected to the rear side of the protection plate, a second installation frame is connected to the left and right sides of the first installation frame, a worm is rotatably connected to the second installation frame, and the worm is meshed with the adjacent worm gear.

[0007] Furthermore, a buffer mechanism is included, which includes a damper. The damper is connected to the top and left and right sides of the first installation frame. The rear side of the damper is connected to a contact block that contacts the transformer. A buffer spring is connected between the contact block and the adjacent damper, and the rear side of the contact block is provided with a rubber ball.

[0008] Furthermore, both the left and right parts of the first installation frame are rotatably connected with locking members, and the locking members are threadedly connected to the adjacent slide rails.

[0009] Furthermore, a sealing block is connected to the rear side of the first installation frame, and the sealing block is in contact connection with the transformer.

[0010] Furthermore, the top of the worm is provided with a knob.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The utility model provides different degrees of shielding and protection for the left and right sides of the first installation frame through the protective plate with adjustable angle, and can block possible influencing objects to prevent them from entering the first installation frame and affecting the radiator. When the ambient airflow is large, the worm can be rotated by turning the knob, so that the worm gear drives the protective plate to flip, and the opening and closing angle of the protective plate can be adjusted to achieve a further protection effect. At the same time, because the first installation frame and the radiator are of separate design, it can be more efficient and convenient to inspect and repair the radiator, thereby improving the convenience of inspection and maintenance.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] A transformer heat dissipation protection device, such as Figure 1 and Figure 2 As shown, it includes a first installation frame 1, a slide rail 2 is installed on the ground on the front side of the transformer, there are two slide rails 2, the first installation frame 1 is slidably connected between the slide rails 2, the left and right parts of the first installation frame 1 are rotatably connected with locking members 3, the locking members 3 are threadedly connected to the adjacent slide rails 2, heat dissipation plates 4 are installed on the left and right sides of the first installation frame 1, a radiator 5 is connected to the front side of the transformer, the radiator 5 is located inside the first installation frame 1, a sealing block 6 is connected to the rear side of the first installation frame 1, the sealing block 6 is contact-connected to the transformer, and the left and right sides of the first installation frame 1 are provided with ventilation protection mechanisms 7 for shielding and protection.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the ventilation protection mechanism 7 includes a protection plate 71, and a plurality of protection plates 71 for blocking protection are rotatably connected to the left and right sides of the first installation frame 1, and a worm gear 72 is connected to the rear side of the protection plate 71. The left and right sides of the first installation frame 1 are connected to the second installation frame 74, and the second installation frame 74 is rotatably connected to a worm 73, and the top of the worm 73 has a knob, and the worm 73 is meshed with the adjacent worm gear 72.

[0024] It should be noted that the transformer will release a large amount of heat when working for a long time. In order to effectively protect the transformer, a radiator 5 is generally installed on the transformer. The present device is used to protect the radiator 5 installed on the transformer. When the radiator 5 is working, the protective plate 71 is used to shield and protect the first protective frame. At the same time, due to the presence of the heat sink 4, impurities and possible animals and birds can be blocked to prevent these things from entering the first installation frame 1 and affecting the radiator 5. When the ambient airflow is large, the worm 73 can be rotated by turning the knob, so that the worm gear 72 drives the protective plate 71 to flip, and the opening and closing angle of the protective plate 71 is adjusted to achieve further protection. When the radiator 5 needs to be inspected, in order to improve the convenience of inspection, the locking member 3 is rotated so that the first installation frame 1 is no longer in a locked state. Then the first installation frame 1 can be pulled forward by the handle so that the first installation frame 1 moves forward along the guide rail, so that the first installation frame 1 and the radiator 5 are separated, thereby facilitating the operator to inspect the radiator 5.

[0025] Example 2

[0026] On the basis of Example 1, Figure 1 , Figure 2 and Figure 5As shown, a buffer mechanism 8 is also included, and the buffer mechanism 8 includes a damper 81. The dampers 81 are connected to the top and left and right sides of the first installation frame 1. The rear side of the damper 81 is connected to a contact block 83 that contacts the transformer. A buffer spring 82 is connected between the contact block 83 and the adjacent damper 81, and the rear side of the contact block 83 is provided with a rubber ball.

[0027] It should be noted that when the first installation frame 1 is controlled, the contact block 83 can make soft contact with the transformer by relying on the action of the damper 81 and the buffer spring 82, thereby avoiding the first installation frame 1 directly colliding with the transformer during the resetting process, causing the transformer to be hit, thereby improving operational safety.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
