Description

Technical Field

[0001] This utility model relates to a lightning protection facility detection device. Background Technology

[0002] Thunderstorms are common in my country during the summer. Lightning carries high current and voltage, and if it strikes buildings, structures, or power systems directly, it can cause serious damage. To prevent lightning from striking buildings and power systems directly, lightning protection devices are used to guide the lightning to the ground. Before installing lightning protection devices, their conductivity needs to be tested. Existing testing devices can only detect the conductivity of the protection devices, but cannot determine which parts of the protection devices are not conductive. Utility Model Content

[0003] The purpose of this invention is to provide a lightning protection facility detection device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A calibration device for testing lightning protection facilities includes a body, a support, an upper hydraulic cylinder, a pressure plate, a protective component to be tested, a fixed plate, and a movable plate. The body has threaded leveling components at its four bottom corners. A screw-mounted support is located on one side of the upper part of the body. The support is L-shaped and extends horizontally across the body. An upper hydraulic cylinder is mounted on the support, and its piston rod is connected to the pressure plate. The protective component to be tested is placed on the body, and the pressure plate can move downwards to contact the component. The component to be tested is made of conductive material. A screw-mounted fixed plate is located on the upper part of the body. The movable plate is positioned opposite the fixed plate, near the support, and connected to the body via a sliding groove formed on the body.

[0006] Preferably, the pressure plate is made of conductive material and is connected to the live wire. The area on the surface of the machine body where the protective component to be tested can be placed is made of conductive material, and the neutral wire is connected to the conductive material of the machine body.

[0007] Preferably, the bottom of the pressure plate is provided with two spheres on both sides, one of which is conductive and the other is made of insulating material. The bracket is provided with two inwardly bent clamping plates, which form a space. The upper hydraulic cylinder is installed in the space via a slider, and the upper hydraulic cylinder can move along the length of the space.

[0008] Preferably, an electromagnet is installed on the pressure plate, and a spring is provided above the electromagnet. The spring is connected to an iron sheet by screws. Three integrally formed conical needles are provided above the iron sheet. The iron sheet is connected to a guide groove via a guide block. The guide groove is opened on the side wall of the pressure plate. A through groove is opened on the surface of the pressure plate for the conical needles to pass through. The attractive force of the electromagnet is greater than the elastic force of the spring.

[0009] Preferably, the movable plate is provided with a lower hydraulic cylinder, and the piston rod of the lower hydraulic cylinder can drive the movable plate to move along the width direction of the machine body.

[0010] Compared with the prior art, this utility model has the following advantages: The design of this utility model is reasonable; the lower hydraulic cylinder can drive the moving plate to adjust its position, thereby changing the distance between the fixed plate and the moving plate to adapt to protective components of different sizes to be tested; the pressure plate, under the action of the upper hydraulic cylinder, can achieve height adjustment to adapt to protective components of different thicknesses to be tested, while the upper hydraulic cylinder can also adjust its position; when testing is required, the moving plate and pressure plate are adjusted according to the protective component to be tested, and the conductive ball on the pressure plate contacts the protective component to be tested. If the protective component to be tested is conductive, the electromagnet inside the pressure plate can attract the iron plate to move the conical needle away from the protective component to be tested. The protective component to be tested can be moved manually or mechanically. When a certain part of the protective component to be tested is not conductive, the electromagnet is not energized, and the spring drives the conical needle to move down to fix the protective component to be tested, thereby understanding the overall conductivity of the protective component to be tested.
