Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage power distribution soft starter control devices, and in particular to a high-voltage power distribution intelligent modular soft starter control device. Background Technology

[0002] A soft starter control device, also known as a soft starter, is a new type of soft starter for medium and high voltage motors. It is mainly suitable for medium and high voltage AC motors below 10KV. It is also a novel motor control device that integrates motor soft starting, soft stopping, light-load energy saving, and multiple protection functions. Its main components are three anti-parallel thyristors connected in series between the power supply and the controlled motor and their electronic control circuit. By using different methods to control the conduction angle of the three anti-parallel thyristors, the input voltage of the controlled motor can be changed according to different requirements, thus achieving different functions. The soft starter control device is also a modular structure.

[0003] However, existing intelligent modular soft starter control devices for high-voltage power distribution are equipped with various control components that control the circuit. These components are connected by wires and fixed by support frames inside the soft starter control device. The spacing between the components is also adjusted by the support frames. However, the distance between the existing support frames is adjusted and fixed by bolts. With long-term use of bolts, the bolts may rust and fall off, causing the components to fall and be damaged. At the same time, bolt fixing does not allow for flexible and convenient adjustment of the support frames, which has certain limitations and affects the efficiency of use.

[0004] Therefore, the existing soft starter control device requires adjusting the distance between its internal support frame by removing bolts, which is a complex, inflexible, time-consuming, and labor-intensive process. To address this, a high-voltage power distribution intelligent modular soft starter control device can be designed. This device features a structure that allows for flexible adjustment of the support frame spacing, making it easy to operate, saving time and effort, and improving subsequent usage efficiency. Utility Model Content

[0005] To overcome the problem that the existing soft start control device requires adjusting the distance between the support frame by removing bolts, which is a complicated, inflexible, time-consuming and labor-intensive process.

[0006] The technical solution of this utility model is as follows: a high-voltage power distribution intelligent modular soft starter control device, including a soft starter control device body, with adjusting brackets provided on both the left and right sides inside the soft starter control device body, a sliding groove opened inside the adjusting bracket, and grooves on both the left and right sides of the sliding groove located on the surface of the adjusting bracket, with slots opened inside the grooves, a first toothed slot provided on one side of the two adjusting brackets, a support frame provided between the rear ends of the two adjusting brackets, a connecting rod passing through the sliding groove on both the left and right sides of the front end face of the two support frames, a locking block fixedly provided on the front end face of the connecting rod, and insertion rods inserted into the slots fixedly provided on both the left and right sides of the rear end face of the locking block, an arc-shaped block sleeved on the outside of the connecting rod, and insertion slots opened at both the upper and lower ends of one side of the arc-shaped block, a spring body provided inside each of the two insertion slots, an insertion body provided on one side of each of the two spring bodies, an extension block fixedly provided on one side of each of the two insertion bodies, a second toothed slot that engages with the first toothed slot on one side of the extension block, and a pull rod provided on the other side of the extension block away from the insertion body.

At the same time, the insert body also disengages from the insert slot. By pushing the support frame, the rear insert rod of the front end locking block disengages from the slot. Then, the connecting rod slides in the sliding groove inside the adjusting bracket to adjust to a suitable position. The lever is then released, allowing the insert body to be inserted into the insert slot inside the arc-shaped block for fixation. Simultaneously, the extension block is also moved, causing the second toothed slot on one side of the extension block to engage with the first toothed slot on one side of the adjusting bracket, thus completing the positioning and fixation.

[0008] Preferably, a rainproof partition is provided at the bottom of the soft starter control device body, and a cabinet door is provided at the front end of the soft starter control device body, with heat dissipation grooves on the surface of the cabinet door.

[0009] Preferably, the control panel is located at the front end of the soft starter control device body and above the cabinet door. The cabinet door and the soft starter control device body are movably connected by a hinge, and a handle is fixedly installed on the front end of the cabinet door.

[0010] Preferably, the snap-fit ​​block has movable slots on both the left and right sides inside, and each movable slot has a compression spring inside, with a plug at the front end of the compression spring.

[0011] Preferably, the arc-shaped block has a fixed through hole inside, through which the connecting rod passes.

[0012] Preferably, the insert body is inserted into the insert groove, and the outer surface of the pull rod is fitted with an anti-slip rubber sleeve.

[0013] Preferably, the connecting rod and the slide groove are connected through and slidably connected, and a moisture-proof plate is provided on the rear end face inside the soft start control device body.

[0014] The beneficial effects of this utility model are:

[0015] By pulling the lever, the extension block on one side and the first toothed slot move, causing the first toothed slot to disengage from the second toothed slot. At the same time, the insert body also disengages from the insert slot. By pushing the support frame, the front end locking block and the rear end insert rod disengage from the slot. Then, the connecting rod slides in the groove inside the adjusting bracket to adjust to the appropriate position. Releasing the lever allows the insert body to be inserted into the insert slot inside the arc-shaped block for fixation. Simultaneously, the extension block is also moved, causing the second toothed slot on one side of the extension block to engage with the first toothed slot on the side of the adjusting bracket, thus completing the positioning and fixation. The structure with adjustable support frame spacing facilitates operation, saves time and effort, and improves subsequent usage efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment: a high-voltage power distribution intelligent modular soft starter control device, including a soft starter control device body 1. Adjustable brackets 3 are provided on both the left and right sides inside the soft starter control device body 1. A sliding groove 7 is formed inside the adjustable bracket 3. Grooves 5 are formed on both the left and right sides of the sliding groove 7 on the surface of the adjustable bracket 3. Slots 9 are formed inside the grooves 5. A first toothed slot 8 is provided on one side of each of the two adjustable brackets 3. A support frame 4 is provided between the rear ends of the two adjustable brackets 3. Connecting rods 12, passing through the sliding grooves 7, are provided on both the left and right sides of the front ends of the two support frames 4. The front ends of the connecting rods 12... A snap-fit ​​block 6 is fixedly installed. Insert rods 11 are fixedly installed on both the left and right sides of the rear end face of the snap-fit ​​block 6, which are inserted into the slots 9. An arc-shaped block 10 is sleeved on the outside of the connecting rod 12. Insertion slots 17 are opened at the upper and lower ends of one side of the arc-shaped block 10. Spring bodies 18 are installed inside the two insertion slots 17. Insertion bodies 19 are installed on one side of the two spring bodies 18. An extension block 14 is fixedly installed on one side of the two insertion bodies 19. A second toothed slot 16 is provided on one side of the extension block 14, which engages with the first toothed slot 8. A pull rod 13 is provided on the other side of the extension block 14 away from the insertion body 19.

[0025] Please see Figures 1-2 In this embodiment, a rainproof partition is provided below the soft start control device body 1, and a cabinet door 2 is provided at the front end of the soft start control device body 1. The surface of the cabinet door 2 has heat dissipation grooves. A control panel is located at the front end of the soft start control device body 1 and above the cabinet door 2. A hinge connects the cabinet door 2 and the soft start control device body 1. A handle is fixedly provided on the front end of the cabinet door 2. A connecting rod 12 passes through and slides through the slide groove 7. A moisture-proof plate is provided on the rear end face inside the soft start control device body 1. First, pulling the pull rod 13 causes it to move the extension block 14 on one side to one side. When the extension block 14 moves, the second toothed slot 16, which is engaged with the first toothed slot 8, also disengages from the fixed position. At the same time, the insert body 19 at both ends of the extension block 14 also disengages from the insert slot 17. Simultaneously, the spring body 18 connected between the insert body 19 and the inner wall of the insert slot 17 is stretched. At this time, the support frame 4 can be pushed, causing its front connecting rod 12 and the locking block 6 to move forward, so that the rear insert rod 11 of the locking block 6 disengages from the slot 9 and then slides in the sliding groove 7 inside the adjusting bracket 3 through the connecting rod 12.

[0026] Please see Figures 3-6In this embodiment, movable slots are provided on both the left and right sides inside the snap-fit ​​block 6. Compression springs are provided inside the two movable slots. Insert rods 11 are provided at the front end of the compression springs. Fixed through holes 15 are provided inside the arc-shaped block 10. The connecting rod 12 passes through the arc-shaped block 10 through the fixed through holes 15. The insert body 19 is inserted into the insert slot 17. The outer surface of the pull rod 13 is fitted with an anti-slip rubber sleeve. After adjusting to a suitable position, the pulled rod 13 is released, so that it is anti-loosened and ejected by the spring body 18, so that the insert body 19 is inserted into the insert slot 17 inside the arc-shaped block 10 for fixation. At the same time, the extension block 14 is also moved, so that the second toothed slot 16 on one side of the extension block 14 engages with the first toothed slot 8 on one side of the adjusting bracket 3 to complete the positioning and fixation. The structure of flexibly adjusting the spacing of the support frame 4 is convenient to operate, saves time and effort, and improves the efficiency of subsequent use.

[0027] During operation, first pull the lever 13, causing the extension block 14 on one side to move to one side. At this time, the second toothed groove 16, which was engaged with the first toothed groove 8 on one side of the extension block 14, also disengages. Simultaneously, the insert bodies 19 at both ends of the extension block 14 disengage from the insert grooves 17. At the same time, the spring body 18 connecting the insert body 19 and the inner wall of the insert groove 17 is stretched. This allows the support frame 4 to be pushed, causing its front connecting rod 12 and the locking block 6 to move forward, thus disengaging the rear insert rod 11 of the locking block 6 from the slot 9. Then, the connecting rod 12 slides in the groove 7 inside the adjusting bracket 3. After adjusting to the appropriate position, the pulled rod 13 is released, so that it is anti-loosened by the spring body 18 and popped out, so that the insert body 19 is inserted into the insert groove 17 inside the arc block 10 for fixation. At the same time, the extension block 14 is also moved to move, so that the second toothed groove 16 on one side of the extension block 14 engages with the first toothed groove 8 on one side of the adjusting bracket 3 to complete the positioning and fixation. The structure of flexibly adjusting the spacing of the support frame 4 is convenient to operate, saves time and effort, and improves the efficiency of subsequent use.

[0028] Through the above steps, by pulling the lever 13, the extension block 14 on one side and the first toothed slot 8 are moved, so that the first toothed slot 8 and the second toothed slot 16 are disengaged. At the same time, the insert body 19 is also disengaged from the insert slot 17. By pushing the support frame 4, the front end locking block 6 and the rear end insert rod 11 are disengaged from the slot 9. This solves the problem that the support frame 4 inside the existing soft start control device needs to be adjusted by removing the bolts, which is complicated, inflexible, time-consuming and labor-intensive.
