Description

Technical Field

[0001] The utility model belongs to the technical field of inverter detection, and specifically relates to a detection device for inverter faults with an alarm function. Background Art

[0002] An inverter is a converter that converts direct current into alternating current. The main body of the inverter is an inverter circuit, and it also includes control, protection, and filtering circuits. Inverters are mainly divided into two categories. One is classified according to the nature of the wave string, and the other is classified according to the nature of the power source. The characteristics of the inverter are high conversion efficiency, fast startup, good safety performance, good physical performance, strong load adaptability and stability. When the inverter fails, detection equipment is needed to detect and process it. A detection device with an alarm function is to install an alarm indicator outside the detection equipment, which will emit an alarm reminder during the detection and fault repair.

[0003] However, during the detection of existing inverter detection equipment, the inverter may slide, resulting in deviation of the detection results. Therefore, a detection device for inverter faults with an alarm function is needed to improve the above problems. Summary of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a detection device for inverter faults with an alarm function, which solves the problem that the inverter may slide during the detection of existing inverter detection equipment, resulting in deviation of the detection results.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A detection device for inverter faults with an alarm function, including a bottom plate, a fixed frame is provided on the bottom plate, a support plate is provided on the fixed frame, a clamping plate is lapped on the support plate, an anti-slip soft pad is provided on the side of the clamping plate, a sliding rod is provided under the clamping plate, two fixed rods are provided in the fixed frame, a fixed block is provided on the side of the fixed rod, two moving blocks are slidably connected to the side of the fixed rod, the moving block is connected to the sliding rod, a first connecting rod is hinged under the fixed block through a pin shaft, both ends of the first connecting rod are hinged under the moving block through a pin shaft, a second connecting rod is hinged under the fixed block through a pin shaft, both ends of the second connecting rod are hinged under the moving block through a pin shaft, and an electric hydraulic rod is provided on the side of the fixed frame.

At the same time, the anti-slip soft pad 10 plays a good protective role on the inverter. A sliding rod 13 is provided under the clamping plate 11, and a sliding hole 9 is lapped on the side of the sliding rod 13. By setting the sliding hole 9 and the sliding rod 13, the sliding hole 9 plays a supporting and limiting role on the sliding rod 13, so that the sliding rod 13 slides smoothly in the sliding hole 9. The sliding hole 9 is opened on the support plate 12. Two fixed rods 15 are provided in the fixed frame 3, a fixed block 18 is provided on the side of the fixed rod 15, and two moving blocks 14 are slidably connected to the side of the fixed rod 15. By setting the fixed rod 15, the moving block 14 and the fixed block 18, the fixed rod 15 plays a supporting and limiting role on the moving block 14 and the fixed block 18, so that the moving block 14 slides smoothly on the surface of the fixed rod 15, and at the same time, it also ensures that the fixed block 18 does not shake randomly on the surface of the fixed rod 15;

[0021] The moving block 14 is connected to the sliding rod 13. A first connecting rod 19 is hinged under the fixed block 18 through a pin shaft. Both ends of the first connecting rod 19 are hinged under the moving block 14 through pin shafts. A second connecting rod 20 is hinged under the fixed block 18 through a pin shaft. Both ends of the second connecting rod 20 are hinged under the moving block 14 through pin shafts. The first connecting rod 19 and the second connecting rod 20 overlap. An electro-hydraulic rod 4 is provided on the side surface of the fixed frame 3. By providing the electro-hydraulic rod 4, the first connecting rod 19 and the second connecting rod 20, and through the mutual cooperation of the electro-hydraulic rod 4, the first connecting rod 19 and the second connecting rod 20, the two moving blocks 14 can be made to approach or move away from each other. A connecting block 16 is provided on the output shaft of the electro-hydraulic rod 4, and the connecting block 16 is connected to the moving block 14. An adjustment door 2 is provided on the front surface of the fixed frame 3. By providing the adjustment door 2, the adjustment door 2 facilitates the staff to repair the structure inside the fixed frame 3. A storage groove 7 is opened on the support plate 12. By providing the storage groove 7 and the support plate 12, the storage groove 7 plays a role in storing the placement plate 8, so that the inverter on the placement plate 8 is stably located on the support plate 12. Three elastic telescopic rods 17 are provided in the storage groove 7. The top of the elastic telescopic rod 17 is provided with a placement plate 8, and the bottom end of the elastic telescopic rod 17 is connected to the fixed block 18.

[0022] The working principle of the present utility model is as follows:

[0023] During use, first place the inverter on the placement plate 8. The inverter drives the placement plate 8 to move downward under its own gravity, so that the placement plate 8 drives the elastic telescopic rod 17 to move downward until the placement plate 8 is retracted into the storage groove 7 and the elastic telescopic rod 17 is compressed. Subsequently, control the electro-hydraulic rod 4 to drive the connecting block 16 to move in the direction close to the fixed block 18, and the connecting block 16 drives the moving block 14 to move in the direction close to the fixed block 18;

[0024] At the same time, the moving block 14 drives the first connecting rod 19 and the second connecting rod 20 to perform extrusion transmission to the other moving block 14, so that the two moving blocks 14 move in the direction of approaching each other. At the same time, the two moving blocks 14 drive the two sliding rods 13 to move in the direction of approaching each other, so that the two sliding rods 13 drive the two clamping plates 11 and the two anti-slip soft pads 10 to clamp and limit the inverter, and thus the fault detection operation of the inverter can be smoothly carried out.

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense.
