Abstract
Description
Technical Field
[0001] This utility model relates to the field of signal processing technology, and in particular to a precise control device for silicon controlled rectifier trigger pulses. Background Technology
[0002] The thyristor is one of the typical switches used for switching reactive power compensation capacitors. Its triggering principle is to apply a DC positive bias voltage to the gate. Once the thyristor meets the condition that a positive voltage is applied to the anode, the thyristor will be in a continuously conducting state.
[0003] When using thyristor trigger pulse devices, they are often placed on a desktop or the ground, lacking proper protection. They are often subject to accidental bumps and damage, which can lead to damage to internal components. Therefore, most existing devices are equipped with protective shells. However, in order to ensure the heat dissipation of the device, there is often a gap between the protective shell and the device. In the event of a collision, the device is still at risk of being damaged.
[0004] Therefore, we propose a precise control device for thyristor trigger pulses to solve the above problems. Utility Model Content

[0007] Specifically, the heat dissipation mechanism includes two heat sinks and multiple fans. The protective shell has slots on both sides, and heat sinks are installed inside the two slots.

The cylinder is fixedly installed on the bottom inner wall of the limiting chamber, and the linkage base is fixedly installed on the output end of the cylinder. Linkage slots are provided on both sides of the linkage base, and linkage components are provided on the inner side of each of the two linkage slots.

A protrusion is provided on the side of the two locking blocks that are close to each other. The two protrusions are respectively adapted to the corresponding limiting slots, so as to facilitate the positioning mechanism to limit the control host.
[0011] Specifically, the linkage component includes a drive column and a second crank. The drive column is fixedly installed on the inner side of the linkage groove, and the second crank is rotatably sleeved on the drive column.
[0012] Specifically, the flipping assembly includes a fixed post, a U-shaped crank, and a linkage post. The fixed post is fixedly installed on one inner wall of the limiting chamber. The U-shaped crank is rotatably sleeved on the fixed post. Crank grooves are opened at both ends of the U-shaped crank. The other end of the second crank is rotatably installed in the lower crank groove. The linkage post is fixedly installed on the inner side of the upper crank groove, so that the U-shaped crank can flip around the fixed post as the center.
[0013] Specifically, the limiting component includes a first crank and a movable column. The first crank is rotatably sleeved on the linkage column, and the movable column passes through one side of the first crank. A movable groove is provided on one side of the locking block, and the movable column is fixedly installed on the inner wall of one side of the movable groove, so as to facilitate the movement of the locking block by the movable column.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the positioning mechanism can stably install the device in the protective shell, preventing the device from shaking in the protective shell when it is moved or bumped, thus preventing damage to its internal components and increasing the protective effect of the device.

The top of the protective shell 1 is detachably installed with a protective cover 3, and multiple magnetic blocks 4 are fixedly installed on the bottom of the protective cover 3. The multiple magnetic blocks 4 are respectively adapted to the corresponding magnetic bases 5. The surfaces of the multiple magnetic blocks 4 and the multiple magnetic bases 5 are provided with an electromagnetic shielding coating to prevent magnetic force from affecting the equipment.
[0025] In this embodiment, the positioning mechanism includes a cylinder 17, a linkage base 16, two linkage components, two flipping components, and two limiting components. The cylinder 17 is fixedly installed on the bottom inner wall of the limiting chamber, and the linkage base 16 is fixedly installed on the output end of the cylinder 17. Linkage slots are provided on both sides of the linkage base 16, and linkage components are provided on the inner side of the two linkage slots. A flipping component is provided at one end of each of the two linkage components, and a limiting component is provided on one side of each of the two flipping components. A locking block 10 is provided on one side of each of the two limiting components. The two locking blocks 10 are slidably installed on one side inner wall of the limiting chamber. A protrusion is provided on the side of the two locking blocks 10 that is close to each other. The two protrusions are respectively adapted to the corresponding limiting slots, so as to facilitate the positioning mechanism to limit the control host 6.
[0026] In this embodiment, the linkage component includes a drive column 19 and a second crank 18. The drive column 19 is fixedly installed on the inner side of the linkage groove, and the second crank 18 is rotatably sleeved on the drive column 19.
[0027] In this embodiment, the flipping assembly includes a fixed post 15, a U-shaped crank 14, and a linkage post 13. The fixed post 15 is fixedly installed on one inner wall of the limiting chamber. The U-shaped crank 14 is rotatably sleeved on the fixed post 15. Crank grooves are opened at both ends of the U-shaped crank 14. The other end of the second crank 18 is rotatably installed in the lower crank groove. The linkage post 13 is fixedly installed on the inner side of the upper crank groove, so that the U-shaped crank 14 can flip with the fixed post 15 as the center.
[0028] In this embodiment, the limiting component includes a first crank 12 and a movable column 11. The first crank 12 is rotatably sleeved on the linkage column 13. The movable column 11 is rotatably passed through one side of the first crank 12. A movable groove is opened on one side of the locking block 10.

[0029] Working principle: During installation, the operator places the control unit 6 into the protective housing 1, then starts the cylinder 17. The cylinder 17 moves the linkage base 16 downward, which in turn moves the two drive columns 19. The movement of the two drive columns 19 moves the corresponding second cranks 18, which in turn moves the corresponding U-shaped cranks 14. Since both U-shaped cranks 14 are rotatably mounted on their corresponding fixed columns 15, they rotate around their corresponding fixed columns 15. The rotation of the two U-shaped cranks 14 moves the corresponding first cranks 12, which in turn moves the corresponding moving columns 11. The movement of the two moving columns 11 then moves the corresponding moving columns 11. The corresponding card block 10 moves, and the movement of the two card blocks 10 drives the corresponding limit block 9 to move. Both limit blocks 9 are slidably installed on the inner wall of the limit chamber, so the two limit blocks 9 can only move back and forth. The movement of the two limit blocks 9 causes the protrusions set on them to slide into the limit grooves opened on both sides of the same limit block 9, thus completing the limit. Then, the staff installs the protective cover 3, so that the four magnetic blocks 4 at its bottom are connected to the corresponding magnetic base 5. Both the magnetic blocks 4 and the magnetic base 5 are equipped with electromagnetic shielding coatings to prevent magnetic force from affecting the equipment. The two heat sinks 7 and the lead screw fan 8 can effectively dissipate heat from the control host 6 to prevent it from overheating.
[0030] The technological advancements of this invention compared to existing technologies are as follows: the device can be stably installed in the protective housing 1, preventing it from shaking inside the housing 1 and causing damage to its internal components when it is moved or bumped, thus increasing the protective effect of the device. Furthermore, the heat dissipation mechanism installed in the protective housing 1 can effectively dissipate heat from the device and prevent damage to its internal components due to overheating.
