Description

Technical Field

[0001] The utility model relates to the technical field of transformer movement. More specifically, the utility model relates to a resin-cast dry-type power transformer that is convenient for mobile installation. Background Art

[0002] The resin-cast dry-type power transformer is a modern type of power transformer. Its main feature is that it uses environmentally friendly resin as the insulating material, completely immersing the high-voltage winding and the low-voltage winding in it to form an integral enclosed structure, which has better weather resistance and corrosion resistance. However, during the process of transporting it to a suitable position for installation, there are still some problems. For example, since the resin-cast dry-type transformer is sensitive to environmental conditions, especially in humid weather conditions, it is likely to affect its insulation performance or cause other problems, thereby affecting its subsequent use. Currently, for short-distance transformer transportation, the common method is to move and transport it by a small trolley. When it rains, workers need to cover a rainproof cloth outside the trolley with the transformer placed on it for shielding. During the process of moving back and forth, the rainproof cloth is easily blown and falls off, resulting in the power transformer being exposed to a humid environment and being damaged. Moreover, it also takes a long time to unfold and cover the rainproof cloth for arrangement, thus affecting the actual transportation efficiency. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a resin-cast dry-type power transformer that is convenient for mobile installation, so as to solve the problem that in the prior art, during short-distance transformer transportation, the actual transportation efficiency is easily affected when it rains.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A resin-cast dry-type power transformer that is convenient for mobile installation, including

[0005] A trolley pallet, wherein pulleys are sequentially and fixedly installed at the four corners of the bottom of the trolley pallet, and a handrail is fixedly installed at the top of the trolley pallet in the length direction.

[0006] An upper rainproof component, which includes a vertical plate, a one-way control device, a rainproof cloth, a pull rope, and a hook. The bottom of the vertical plate is fixedly installed on the top of the trolley pallet. The one-way control device is arranged in the middle of the two vertical plates. The end of the rainproof cloth is fixedly installed on the outer surface of the one-way control device. The pull rope is fixedly connected to the end of the rainproof cloth away from the one-way control device. The hook is arranged parallel to the pull rope, and the bottom end of the hook is fixedly installed on the top of the trolley pallet away from the one-way control device.

[0007] Among them, it further includes a support plate assembly and a side rain shield assembly. The number of the support plate assemblies is two, and they are symmetrically arranged on both sides in the width direction of the trolley tray. The side rain shield assembly is arranged in the middle of the support plate assembly.

[0008] Among them, the support plate assembly includes a fixed plate, a movable plate, an L-shaped slider, a telescopic frame, and a guiding mechanism. The bottom of the fixed plate is fixedly installed on the top of the trolley tray. The movable plate is arranged parallel to the fixed plate. The bottom of the movable plate is fixedly installed on the top of the L-shaped slider. The outer surface of the L-shaped slider is slidably installed on the inner surface of the movable plate. The telescopic frame is arranged outside the fixed plate and the movable plate. The guiding mechanism is provided on the tops of both the fixed plate and the movable plate.

[0009] Among them, the guiding mechanism includes a guiding plate and a roller. The side surface in the width direction of the guiding plate is fixedly installed on the top of the fixed plate. The roller is arranged inside the guiding plate.

[0010] Among them, the side rain shield assembly includes a first connecting rod, a second connecting rod, a fixed column, and a rain shield curtain. One end of the first connecting rod is fixedly installed on the surface of the telescopic frame, and the other end is fixedly installed on the inner surface of the fixed column. One end of the second connecting rod is fixedly installed on the surface of the telescopic frame, and the other end is slidably installed on the inner surface of the fixed column. Both sides of the rain shield curtain are fixedly installed on the outer surfaces of the two fixed columns respectively.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] In the above solution, by setting the upper rain shield assembly and the support plate assembly, the staff places the power transformer to be moved and transported inside the waterproof plate on the top of the trolley tray. Then, the movable plate is pulled, so that the L-shaped slider at the bottom of the movable plate moves horizontally along the inner surface of the trolley tray and moves away from the fixed plate. The telescopic frame connected to the fixed plate and the movable plate is stretched, so that the movable plate reaches the tail of the trolley tray away from the handrail. Then, the rain shield cloth is pulled by a pull rope, and the rain shield cloth wound around the outer surface of the one-way control device passes through the middle parts of the two symmetrically arranged guiding mechanisms on the tops of the fixed plate and the movable plate in sequence. Then, the pull rope is sleeved outside the hook parallel to the pull rope on the top of the trolley tray, thereby completing the waterproof treatment of the top of the power transformer inside the waterproof plate. The operation is convenient, and the efficiency of transporting the power transformer on rainy days is improved.

[0013] In the above solution, by setting up the side rain shield assembly, during the process of expanding the support plate assembly, connecting rod one connected to the side of the shaft column at the interface of the telescopic frame connecting rod will move horizontally accordingly. When connecting rod two connected to the side of the shaft column at the interface of the telescopic frame connecting rod moves horizontally, it will move downward along the inner surface of the fixed column, and the rain shield will be stretched out, thus completing the waterproof treatment of the side of the power transformer inside the waterproof board.
