Technical Field

[0001] The utility model belongs to the technical field of transformer protection equipment, in particular to a protection structure for an energy-efficient transformer. Background Art

[0002] A transformer is a device that changes the voltage. It can be used to step down or step up the voltage to meet the voltage requirements of different devices and circuits. Energy-efficient transformers belong to a type of transformer equipment. They mainly improve energy efficiency and can use electrical energy more effectively, thereby saving energy.

[0003] The installation location of the transformer will vary depending on the place of use and needs. It can be divided into indoor and outdoor installation. Most indoor installations are in transformer rooms, such as dry and well-ventilated places. When installed outdoors, most of them are installed on overhead brackets or in box-type transformers.

[0004] The box-type transformer can combine the transformer and other devices in a sealed box, which can protect the transformer from rain and other effects. However, the casing of the box-type transformer is generally made of steel plate material, and the contact area with the environment is small, which can easily lead to relatively low heat dissipation effect. Under long-term operation, the box-type transformer is prone to overheating problems, which reduces the service life of the transformer. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model proposes a protective structure for an energy-efficient transformer.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a protective structure for an energy-efficient transformer, comprising a transformer, a mounting frame installed at the bottom of the transformer, a connecting plate connected to one side of the mounting frame, and a sliding rod fixedly connected to the other end of the connecting plate; a limiting block is fixedly connected to the middle of the outer wall of the sliding rod; a spring is fixedly connected to one end of the limiting block, and a water collecting box is fixedly connected to the other end of the spring; the spring is sleeved on the outer wall of the sliding rod, and the water collecting box is slidably connected to the outer wall of the sliding rod; a protective shell is fixedly connected to one side of the outer wall of the water collecting box; a guide plate is obliquely and symmetrically provided on the top of the protective shell.

[0007] Preferably, a connecting frame is clamped on the outer wall of the installation frame; a clamping plate is slidably connected to the inner side of the connecting frame; a screw is rotatably connected to one end of the clamping plate, and the other end of the screw is threadedly penetrated through the interior of the connecting frame.

[0008] Preferably, an electric push rod is installed inside the protective shell, and the output end of the electric push rod passes through the protective shell and is connected to the push rod; a drainage groove is opened on one side of the water collecting box, and a baffle is sealed and connected to the drainage groove through a sealing strip; one end of the push rod is connected to the baffle.

[0009] Preferably, a pressure sensor is installed on the limit block, and a pressure rod is installed on the pressure sensor; the pressure sensor is connected to a PLC controller signal, and the PLC controller is connected to a display signal.

[0010] Preferably, a plurality of groups of support rods are installed on the transformer, and a lead ring is installed at the other end of the support rod; and an electric wire is arranged inside the lead ring.

[0011] Preferably, the clamping plate and the inner facing surfaces of the connecting frame are both provided with rubber pads, and a warning sign is provided on one side of the outer wall of the protective shell.

[0012] Preferably, the protective shell, the guide plate and the water collecting box are all made of a lightweight insulating material, and the lightweight insulating material is made of fiberglass plastic.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model provides a protective structure for an energy-efficient transformer. As rainwater continuously falls into the water collecting box, the weight of the water collecting box gradually increases. When the weight exceeds the bearing capacity of the spring, the water collecting box will slide down along the sliding rod, and at the same time, the protective shell will be pulled down, so that the protective shell can shield the top of the transformer and most of the external area, reduce the continuous pouring of rain on the transformer, and achieve the effect of protecting the transformer. When the weather clears up, the rainwater continues to evaporate, and the protective shell rises through the spring, so that the protective shell gradually resets and moves away from the transformer, reducing the impact on the normal heat dissipation of the transformer. The structures of the water collecting box and the protective shell are relatively simple, and can be modified on the basis of the transformer, saving costs. At the same time, one end of the guide plate extends to the upper middle part of the water collecting box, which can collect rainwater falling on the protective shell and guide it to the water collecting box, increasing the speed and efficiency of rainwater entering the water collecting box, and improving the speed of accumulating rainwater, so that the water collecting box reaches a sufficient weight in a relatively short time, thereby triggering the descending mechanism of the protective shell.

[0015] 2. The utility model provides a protective structure for an energy-efficient transformer. The position of the clamping plate inside the connecting frame can be adjusted by rotating the screw rod forward and backward, which can facilitate the installation of transformers of different models, so that the device can be connected and installed with most types of transformers, thereby improving the applicability of the protective structure.
