Description

Technical Field

[0001] The invention relates to the technical field of high-voltage solid-state soft starting, in particular to a high-voltage solid-state soft starting device with an intelligent protective shell. Background Art

[0002] The motor soft starter is an advanced soft start device designed and produced using power electronics technology, microprocessing technology and modern control theory. It can effectively limit the current when the AC motor starts and can be widely used in loads such as fans, water pumps, compressors, etc. It is an ideal replacement product for traditional soft start devices such as star / delta conversion, auto-coupling step-down, and magnetic control step-down. High-voltage solid-state soft starters use technical means such as step-down or frequency conversion to achieve smooth starting of motors and mechanical loads and reduce starting current. Conventional high-voltage solid-state soft starters use semi-controlled devices such as thyristors and AC-AC voltage regulation. Their output can adjust the voltage but not the frequency. Fully controlled intelligent high-voltage solid-state soft starters use fully controlled power semiconductor devices such as IGBTs, AC-DC-AC voltage and frequency regulation, and PWM inverters in series to superimpose high voltage output, achieving high-voltage output with variable frequency and voltage, and supplying power to the motor with variable frequency and voltage. It generally consists of four parts: phase-shifting transformer, power unit, main control unit, and input and output. During the motor starting process, the voltage and frequency are gradually increased to keep the motor starting current at a low level, while ensuring sufficient starting torque, thereby reducing the impact on the power grid.

[0003] High-voltage solid-state soft start devices are usually used in scenarios where fans, water pumps, compressors and other devices are frequently used and where there is frequent movement of personnel or materials. The protection performance of common high-voltage solid-state soft start devices on the market is poor. They are easily damaged by collision with foreign objects in places where there are dense personnel and materials. In addition, there is a large amount of dust in places where there is dense movement of personnel and materials. The high-voltage solid-state soft start device is very easy to inhale external dust during the heat dissipation process, and the dust is also difficult to be effectively discharged during the heat dissipation process. This causes the high-voltage solid-state soft start device to easily malfunction and short-circuit due to excessive internal dust.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-voltage solid-state soft starting device with an intelligent protective shell is proposed. Summary of the invention

[0014] Furthermore, the rotating protective plate is rotatably connected to the side wing plate, and the side wing plate and the bonding plate are an integrated structure.

[0015] Furthermore, the bonding plate is bonded to the outer surface of the high-voltage solid-state soft start box, and the inner contour size of the docking groove matches the outer contour size of the telescopic docking rod.

[0016] The present invention provides a high voltage solid-state soft start device with an intelligent protective housing, which has the following features:

[0017] Beneficial effects:

[0018] 1. The present invention works through the suction fan, and the adsorption force can be transmitted from the suction groove to the inside of the high-voltage solid-state soft-start box, so that the high temperature generated during the working process of the high-voltage solid-state soft-start box and the dust entering the high-voltage solid-state soft-start box can be sucked into the inside of the connecting seat through the suction groove. The dust collecting seat is provided with a dust collecting net, which can allow air to pass through and leave dust. This allows the suction fan to suck the hot air from the inside of the high-voltage solid-state soft-start box out of the equipment through the exhaust groove during the suction process, and the sucked dust is attached to the inside of the dust collecting seat. During the working process of the high-voltage solid-state soft-start box, if the two wings of the high-voltage solid-state soft-start box are hit by foreign objects, the foreign objects will contact the side wing plates. After the side wing plates are squeezed, they will drive the connecting seat to slide inside the high-voltage solid-state soft-start box, which allows the docking plate to stretch The buffer spring rod is deformed, and the impact on the high-voltage solid-state soft start box can be effectively absorbed by deforming the buffer spring rod, thereby avoiding the impact of foreign objects on the normal operation of the high-voltage solid-state soft start box. Through the above design, by integrating the heat dissipation components inside the protective shell, the functions of the equipment can be highly integrated. At the same time, this design can effectively distinguish the working parts and auxiliary parts inside the high-voltage solid-state soft start box, thereby facilitating subsequent maintenance and cleaning. In addition, the docking plate can be disassembled by removing the bolts and the connecting seat to realize the rapid separation of the side protection assembly and the high-voltage solid-state soft start box. When the side wing plate is damaged due to impact or the internal air suction component is damaged or the internal air duct needs to be cleaned, the side protection assembly and the high-voltage solid-state soft start box can be quickly disassembled, replaced or repaired.

[0019] 2. When the side wing plate of the present invention is in a normal position, the through groove will be connected with the one-way exhaust valve. During the process of the suction fan sucking air, the suction force will enter the air control chamber through the through groove and the one-way exhaust valve, so that the air at the bottom end of the first piston block will be gradually discharged. After the air at the bottom end of the first piston block is discharged, the first piston block will stretch the reset spring rod under the action of the air pressure difference at both ends and displace inside the air control chamber. The first piston block drives the second piston block to displace synchronously through the linkage rod, so that the first piston block and the second piston block can move synchronously to the bottom of the air control chamber with the air pressure difference. When the side wing plate is displaced by collision, the connecting seat will cause the through groove and the one-way exhaust valve to be offset after displacement, and the ash inlet port will be connected with the one-way air inlet valve. After the through groove and the one-way exhaust valve are offset, the first piston block will be pulled due to the loss of suction force. As the reset spring rod is reset and moved upward, and the ash inlet is connected to the one-way air inlet valve, the dust collected in the ash collecting seat will enter the air control chamber through the ash discharge groove, the ash inlet and the one-way air inlet valve due to the suction force generated when the second piston block moves upward synchronously with the first piston block. Through this design, the equipment can automatically clean the collected dust when it is hit, and after the side wing plate is reset, the first piston block drives the second piston block to move downward again, and the second piston block can push the dust collected in the air control chamber to be discharged from the equipment through the one-way ash discharge port. In addition, through the operation of the electromagnet, the electromagnet can adsorb the side wing plate. Through this design, even if the side wing plate is not impacted, the equipment can displace it to achieve dust cleaning. The function of the electromagnet adsorbing the side wing plate can also be used to determine whether the side wing plate can be normally displaced under force during equipment maintenance.

[0020] 3. The staff of the present invention can pull the rotating protective plate to rotate the rotating protective plate through the rotating shaft, so that the rotating protective plate can cover the front end of the high-voltage solid-state soft-start box and make the bonding plate fit with the high-voltage solid-state soft-start box. After the bonding of the bonding plate and the high-voltage solid-state soft-start box is completed, the staff can pull the extended telescopic docking rod to make the telescopic docking rod extend into the docking groove, and the rotation of the rotating protective plate can be locked by docking the telescopic docking rod with the docking groove. The rotating protective plate can stably cover the front end of the high-voltage solid-state soft-start box through the support of the bonding plate and the high-voltage solid-state soft-start box, which can effectively ensure the protection of the rotating protective plate to the front end of the high-voltage solid-state soft-start box. In addition, during the protection process of the high-voltage solid-state soft-start box by the rotating protective plate, The bonding plate is bonded to the high-voltage solid-state soft-start box, and the rotation of the rotating protective plate is locked, which can effectively prevent the cabinet door of the high-voltage solid-state soft-start box from being accidentally opened. In addition, when the side wing plate is squeezed and displaced, it can drive the rotating protective plate to move synchronously, and the telescopic docking rod can penetrate into the docking groove to avoid interference with the displacement of the rotating protective plate. During the displacement of the rotating protective plate, the bonding plate can be displaced on the surface of the high-voltage solid-state soft-start box. If there is a dimensional error between the high-voltage solid-state soft-start box and the bonding plate, or if there is a gap in the cabinet door of the high-voltage solid-state soft-start box due to other reasons, the displacement of the bonding plate to the high-voltage solid-state soft-start box can effectively push the opened cabinet door to close. Through this design, the working stability and safety of the high-voltage solid-state soft-start box can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific operation is as follows: after the connecting seat 602 passes through the through grooves on both sides of the interior of the high-voltage solid-state soft-start box 1, it can be fixed with the buffer spring rod 7 to achieve docking with the high-voltage solid-state soft-start box 1. During the use of the high-voltage solid-state soft-start box 1, the suction fan 605 works, and the adsorption force can be transmitted from the suction groove 607 to the interior of the high-voltage solid-state soft-start box 1, so that the high temperature generated during the operation of the high-voltage solid-state soft-start box 1 and the dust entering the interior of the high-voltage solid-state soft-start box 1 can be sucked into the interior of the connecting seat 602 through the suction groove 607. A dust collecting net is laid inside the dust collecting seat 606, which can allow air to pass through and leave dust. During the suction process of the suction fan 605, the hot air sucked out of the interior of the high-voltage solid-state soft-start box 1 can be discharged from the equipment through the exhaust groove 604, and the sucked dust can be attached to the inside of the dust collecting seat 606. During the operation of the high-voltage solid-state soft-start box 1, if the two wings of the high-voltage solid-state soft-start box 1 are hit by foreign objects, the foreign objects will contact the side wing plates 601. When the side wing plate 601 is squeezed, it will drive the connecting seat 602 to slide inside the high-voltage solid-state soft-start box 1, which enables the connecting plate 603 to stretch the buffer spring rod 7 to deform. By deforming the buffer spring rod 7, the impact on the high-voltage solid-state soft-start box 1 can be effectively absorbed, thereby avoiding the impact of foreign objects on the normal operation of the high-voltage solid-state soft-start box 1. Through the above design, by integrating the heat dissipation components inside the protective shell, the functions of the equipment can be highly integrated.

In addition, the connecting plate 603 can be disassembled from the connecting seat 602 by removing the bolts to realize the rapid separation of the side protection component 6 and the high-voltage solid-state soft-start box 1. When the side wing plate 601 is damaged due to impact or the internal air suction component is damaged or the internal air duct needs to be cleaned, the side protection component 6 and the high-voltage solid-state soft-start box 1 can be quickly disassembled, replaced or repaired.

[0032] See also Figures 1 to 3 as well as Figure 7 and Figure 8The ash discharge component 5 includes an air control chamber 501, a partition 502, a return spring rod 503, a first piston block 504, a linkage rod 505, a second piston block 506, a pressure equalizing groove 507 and a one-way ash discharge port 508. The air control chamber 501 is provided with a partition 502, and a return spring rod 503 is provided on the inner side of the top of the air control chamber 501. The bottom end of the return spring rod 503 is connected to the first piston block 504, and the top outer end of the first piston block 504 is connected to the linkage rod 505. The other end of the linkage rod 505 is provided with the second piston block 506.

When the suction fan 605 is sucking air, the suction force will enter the air control chamber 501 through the through slot 610 and the one-way exhaust valve 3, so that the air at the bottom of the first piston block 504 will be gradually discharged. After the air at the bottom of the first piston block 504 is discharged, the first piston block 504 will stretch the reset spring rod 503 due to the pressure difference at both ends and return to the air control chamber 501. The first piston block 504 drives the second piston block 506 to move synchronously through the linkage rod 505, so that the first piston block 504 and the second piston block 506 can move synchronously to the bottom of the air control chamber 501 with the air pressure difference.

The second piston block 506 can push the dust collected in the air control chamber 501 to be discharged from the equipment through the one-way dust discharge port 508. In addition, the electromagnet 2 works to adsorb the side wing plate 601. Through this design, even if the side wing plate 601 is not impacted, the equipment can displace it to achieve dust cleaning. The function of the electromagnet 2 to adsorb the side wing plate 601 can also be used to determine whether the side wing plate 601 can be normally displaced during equipment maintenance.

[0034] See also Figure 1 and Figure 4 The positive protection component 8 includes a rotating protection plate 801, a bonding plate 802, a docking groove 803 and a telescopic docking rod 804. The rotating protection plate 801 is provided with a bonding plate 802 on one side close to the high-voltage solid-state soft start box 1. The outer end of the rotating protection plate 801 is provided with a docking groove 803, and the outer end of the rotating protection plate 801 is connected with a telescopic docking rod 804. The rotating protection plate 801 is rotatably connected to the side wing plate 601, and the side wing plate 601 and the bonding plate 802 are an integrated structure. The bonding plate 802 is bonded to the outer surface of the high-voltage solid-state soft start box 1, and the inner contour size of the docking groove 803 matches the outer contour size of the telescopic docking rod 804.

[0035] The specific operation is as follows. The staff pulls the rotating protective plate 801 to rotate the rotating protective plate 801 through the rotating shaft, so that the rotating protective plate 801 can cover the front end of the high-voltage solid-state soft-start box 1 and make the bonding plate 802 fit with the high-voltage solid-state soft-start box 1. After the bonding of the bonding plate 802 and the high-voltage solid-state soft-start box 1 is completed, the staff pulls the extended telescopic docking rod 804 to make the telescopic docking rod 804 extend into the docking groove 803. The telescopic docking rod 804 docks with the docking groove 803, so that the rotation of the rotating protective plate 801 can be locked. The rotating protective plate 801 is supported by the bonding plate 802 and the high-voltage solid-state soft-start box 1, so that the rotating protective plate 801 can stably cover the front end of the high-voltage solid-state soft-start box 1, which can effectively ensure that the rotating protective plate 801 protects the front end of the high-voltage solid-state soft-start box 1.

In addition, when the side wing plate 601 is squeezed and displaced, the rotating protective plate 801 can be driven to move synchronously, and the telescopic docking rod 804 can penetrate into the docking groove 803 to avoid interference with the displacement of the rotating protective plate 801. During the displacement of the rotating protective plate 801, the bonding plate 802 can be displaced on the surface of the high-voltage solid-state soft-start box 1. If there is a size error between the high-voltage solid-state soft-start box 1 and the bonding plate 802, or if there is a gap in the cabinet door of the high-voltage solid-state soft-start box 1 due to other reasons, the displacement of the bonding plate 802 to the high-voltage solid-state soft-start box 1 can effectively push the opened cabinet door to close. Through this design, the working stability and safety of the high-voltage solid-state soft-start box 1 can be further improved.

[0036] In summary, when the high-voltage solid-state soft-start device with an intelligent protective shell is used, first, the connecting seat 602 passes through the through grooves on both sides of the interior of the high-voltage solid-state soft-start box 1, and then can be fixed with the buffer spring rod 7 to achieve docking with the high-voltage solid-state soft-start box 1. During use, the high-voltage solid-state soft-start box 1 works through the suction fan 605, and the adsorption force can be transmitted from the suction groove 607 to the interior of the high-voltage solid-state soft-start box 1, so that the high temperature generated during the operation of the high-voltage solid-state soft-start box 1 and the dust entering the interior of the high-voltage solid-state soft-start box 1 can be sucked into the connecting seat 602 through the suction groove 607. The dust collecting seat 606 is provided with a dust collecting net, which can allow air to pass through and leave dust. This allows the suction fan 605 to discharge the hot air sucked out of the interior of the high-voltage solid-state soft-start box 1 through the exhaust groove 604 during the suction process, and the sucked dust is attached to the interior of the dust collecting seat 606;

[0037] Then, during the operation of the high-voltage solid-state soft-start box 1, if the two wings of the high-voltage solid-state soft-start box 1 are hit by foreign objects, the foreign objects will contact the side wing plates 601. After the side wing plates 601 are squeezed, they will drive the connecting seat 602 to slide inside the high-voltage solid-state soft-start box 1, which enables the docking plate 603 to stretch the buffer spring rod 7 to produce deformation. By deforming the buffer spring rod 7, the impact on the high-voltage solid-state soft-start box 1 can be effectively absorbed, thereby avoiding the impact of foreign objects on the normal operation of the high-voltage solid-state soft-start box 1. Through the above design, by The components are integrated inside the protective shell, which can make the functions of the equipment highly integrated. At the same time, this design can effectively distinguish the working components and auxiliary components inside the high-voltage solid-state soft start box 1, so as to facilitate the subsequent maintenance and cleaning. In addition, the docking plate 603 can be disassembled from the connecting seat 602 by removing the bolts to realize the rapid separation of the side protection component 6 and the high-voltage solid-state soft start box 1. When the side wing plate 601 is damaged due to impact or the internal air suction component is damaged or the internal air duct needs to be cleaned, the side protection component 6 and the high-voltage solid-state soft start box 1 can be quickly disassembled, replaced or repaired;

[0038] Then, when the side wing plate 601 is in a normal position, the through slot 610 will be connected to the one-way exhaust valve 3. When the suction fan 605 is sucking air, the suction force will enter the air control chamber 501 through the through slot 610 and the one-way exhaust valve 3, so that the air at the bottom of the first piston block 504 will be gradually discharged. After the air at the bottom of the first piston block 504 is discharged, the first piston block 504 will stretch the return spring rod 503 due to the pressure difference at both ends and move inside the air control chamber 501. The first piston block 504 drives the second piston block 506 to move synchronously through the linkage rod 505, so that the first piston block 504 and the second piston block 506 can move synchronously to the bottom of the air control chamber 501 with the pressure difference.

[0039] Subsequently, when the side wing plate 601 is displaced by collision, the connecting seat 602 will cause the through groove 610 to be offset from the one-way exhaust valve 3 after displacement, and the ash inlet 609 to be connected with the one-way air inlet valve 4. After the through groove 610 is offset from the one-way exhaust valve 3, the first piston block 504 will move upward with the reset spring rod 503 due to the loss of suction force, and after the ash inlet 609 is connected with the one-way air inlet valve 4, the dust collected in the ash collecting seat 606 will enter the air control chamber 501 through the ash discharge groove 608, the ash inlet 609 and the one-way air inlet valve 4 due to the suction force generated when the second piston block 506 moves upward synchronously with the first piston block 504. Through this design, the device can automatically clean the collected dust when it is impacted, and after the side wing plate 601 is reset, the first piston block 504 drives the second piston block 506 to move down again, and the second piston block 506 can push the dust collected in the air control chamber 501 to be discharged from the device through the one-way dust discharge port 508. In addition, through the operation of the electromagnet 2, the electromagnet 2 can adsorb the side wing plate 601. Through this design, even if the side wing plate 601 is not impacted, the device can displace it to achieve dust cleaning. The function of the electromagnet 2 adsorbing the side wing plate 601 can also be used to determine whether the side wing plate 601 can be normally displaced during the equipment maintenance process.

[0040] Then, the staff can pull the rotating protective plate 801 to rotate the rotating protective plate 801 through the rotating shaft, so that the rotating protective plate 801 can cover the front end of the high-voltage solid-state soft-start box 1, and make the bonding plate 802 bond with the high-voltage solid-state soft-start box 1. After the bonding of the bonding plate 802 and the high-voltage solid-state soft-start box 1 is completed, the staff can pull the extended telescopic docking rod 804 to make the telescopic docking rod 804 extend into the docking groove 803. The telescopic docking rod 804 is docked with the docking groove 803 to lock the rotation of the rotating protective plate 801. The rotating protective plate 801 can stably cover the front end of the high-voltage solid-state soft-start box 1 through the support of the bonding plate 802 and the high-voltage solid-state soft-start box 1, which can effectively ensure that the rotating protective plate 801 protects the front end of the high-voltage solid-state soft-start box 1;

[0041] Finally, during the process of rotating the protective plate 801 protecting the high-voltage solid-state soft-start box 1, since the bonding plate 802 is bonded to the high-voltage solid-state soft-start box 1 and the rotation of the rotating protective plate 801 is locked, this can effectively prevent the cabinet door of the high-voltage solid-state soft-start box 1 from being accidentally opened. In addition, when the side wing plate 601 is squeezed and displaced, it can drive the rotating protective plate 801 to move synchronously, and the telescopic docking rod 804 can penetrate into the docking groove 803 to avoid interference with the displacement of the rotating protective plate 801. During the displacement of the rotating protective plate 801, the bonding plate 802 can be displaced on the surface of the high-voltage solid-state soft-start box 1. If there is a dimensional error between the high-voltage solid-state soft-start box 1 and the bonding plate 802, or if there is a gap in the cabinet door of the high-voltage solid-state soft-start box 1 due to other reasons, the displacement of the bonding plate 802 to the high-voltage solid-state soft-start box 1 can effectively push the opened cabinet door to close. Through this design, the working stability and safety of the high-voltage solid-state soft-start box 1 can be further improved.
