Technical Field

[0001] The utility model relates to the field of voltage stabilizers, in particular to an electronic voltage regulating voltage stabilizer. Background Art

[0002] The voltage stabilizer is a device that stabilizes the output voltage. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, causing the position of the voltage regulator's carbon brush to change, and automatically adjusts the coil turns ratio to maintain the output voltage stable.

[0003] After searching, a Chinese patent discloses a precision voltage regulator (publication number CN 215935341 U). This patented technology can drive most of the components in the box to extend outward through the arrangement of a transmission mechanism and a first mounting plate and a second mounting plate, thereby reducing the difficulty of maintenance and overhaul and facilitating the operation of maintenance personnel. However, in the technical solution of the above patent document, a worm gear is used to drive two worm gears to rotate, resulting in too low transmission efficiency and large transmission loss. At the same time, after the mounting plate is extended, the lower side is suspended without support and is prone to deformation.

[0004] Therefore, an electronic voltage regulator is proposed to solve the above problem. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, an electronic voltage regulator and voltage stabilizer comprises: an installation box 1, the inner wall of the installation box 1 is slidably connected to a mounting platform 2, the upper end of the installation platform 2 is fixedly connected to a voltage regulator and voltage stabilizing component 3, and the side end of the installation box 1 is movably hinged with a switch door 4; a pushing mechanism 5, which is used to push the mounting platform 2 out for easy maintenance and is arranged on one side of the installation box 1; a supporting mechanism 6, which is used to support and protect the mounting platform 2 when the pushing mechanism 5 pushes out the mounting platform 2 to repair the voltage regulator and voltage stabilizing component 3 and is arranged on the lower side of the mounting platform 2; wherein the pushing mechanism 5 comprises a driving component 501 arranged on one side of the installation box 1, and a synchronous transmission component 502 is arranged on one side of the driving component 501. When the device needs to perform maintenance and repair on the voltage regulator and voltage stabilizing component 3, the driving component 5 is first started. 01, the driving component 501 drives the synchronous transmission component 502 to rotate, and the synchronous transmission component 502 synchronously drives the two sides of the driving component 501 to rotate, pushing the mounting platform 2 and the voltage regulating and stabilizing component 3 to extend, so that the voltage regulating and stabilizing component 3 can be maintained and repaired. When the mounting platform 2 is extended, the supporting mechanism 6 supports the lower side of the mounting platform 2 to prevent the lower side from being deformed and damaged when the mounting platform 2 is extended. The mounting platform 2 is "L" shaped, and the surface can be used for the installation of the voltage regulating and stabilizing component 3. A threaded hole is opened on the side end to cooperate with the driving component 501. The voltage regulating and stabilizing component 3 is composed of a voltage regulating circuit, a control circuit and a servo motor, etc., which can realize voltage regulation and stabilization in the circuit. For the staff in this technical field, the voltage regulating and stabilizing component 3 is the prior art and will not be described in detail here.

[0024] like Figure 3 and Figure 4As shown, the driving assembly 501 includes two lead screws 5011 rotatably connected to the inner wall of the installation box 1, the two lead screws 5011 are both threadedly connected to the installation platform 2, a worm gear 5014 is fixedly connected to the surface of the lead screw 5011, a three-phase asynchronous motor 5012 is fixedly connected to the side end of the installation box 1, a worm 5013 is fixedly connected to the output end of the three-phase asynchronous motor 5012, the worm 5013 is meshedly connected with the worm gear 5014, when it is necessary to drive the installation platform 2 to extend, the three-phase asynchronous motor 5012 can be manually started at this time, so that the three-phase asynchronous motor 5012 drives the worm 5013 to rotate, the worm 5013 drives the worm gear 5014 to rotate, and the worm gear 5014 drives the worm 5013 to rotate. One of the lead screws 5011 rotates, and the synchronous transmission assembly 502 includes a synchronous transmission belt 5022 and a synchronous pulley 5021 fixedly connected to the surfaces of the two lead screws 5011. The two synchronous pulleys 5021 are meshed and transmitted through the synchronous transmission belt 5022. When the lead screw 5011 rotates, the synchronous pulley 5021 is driven to rotate. The synchronous pulley 5021 makes the two lead screws 5011 rotate synchronously through the synchronous transmission belt 5022. At this time, the two lead screws 5011 rotate at the same time, driving the mounting platform 2 to extend out of the mounting box 1, and then manually turning off the three-phase asynchronous motor 5012. At this time, the voltage regulating and stabilizing assembly 3 on the upper side of the mounting platform 2 can be maintained and repaired. The maintenance is completed, at this time, the three-phase asynchronous motor 5012 is manually turned on to reverse, so the worm 5013 and the worm wheel 5014 are reversed, and the two lead screws 5011 are driven to reverse through the synchronous transmission component 502, and the mounting table 2 is retracted into the mounting box 1, and the three-phase asynchronous motor 5012 is manually turned off. At this time, the switch door 4 is closed to complete the installation and maintenance. For the staff in this technical field, the three-phase asynchronous motor 5012 is a prior art and will not be further described here. The driving component 501 also includes a rotating seat 5015 fixedly connected to the side end of the mounting box 1, and the worm 5013 is rotatably connected to the inner wall of the rotating seat 5015. When the worm 5013 rotates, it is away from the three-phase asynchronous motor. One end of the machine 5012 is prone to swing, making the engagement with the worm wheel 5014 unstable. The rotation of the worm 5013 is limited by the rotating seat 5015, so that when the worm 5013 rotates, it is not easy to swing. The worm 5013 can stably mesh with the worm wheel 5014 for transmission. A shielding box 8 is fixedly connected to the surface of the mounting table 2. The shielding box 8 is slidably connected to the inner wall of the mounting box 1. The shielding box 8 is arranged on the surface of the lead screw 5011. The shielding box 8 can be used to protect and shield the lead screw 5011 on the inner wall of the mounting box 1 to prevent the connecting wire harness of the voltage regulating and stabilizing component 3 from being hooked on the lead screw 5011 when it is scattered, causing wear or hooking damage.

[0025] like Figure 1 and Figure 2As shown, the support mechanism 6 includes two support rods 602 fixedly connected to the lower end of the mounting platform 2, and two slide grooves 601 are provided on the lower inner wall of the mounting box 1. The two support rods 602 are slidably connected to the inner walls of the two slide grooves 601 respectively. When the mounting platform 2 is extended from the mounting box 1, the support rods 602 can play the role of reinforcing ribs to reinforce the lower side of the mounting platform 2 to prevent the mounting surface of the mounting platform 2 from being deformed. At the same time, the support rods 602 can limit the sliding direction of the mounting platform 2 to prevent the mounting platform 2 from tilting when sliding. The inner walls of the two support rods 602 are rotatably connected to the rotating rods 603, and the surfaces of the two rotating rods 603 are rotatably connected to two rollers 604, and the lower side of the mounting platform 2 can be supported by the rollers 604. The support increases the force and force points, reduces the direct pressure on the mounting platform 2, and prevents deformation. At the same time, the roller 604 is arranged on the outside of the mounting box 1, lower than the lower inner wall of the mounting box 1, and will not affect the opening and closing of the switch door 4. The circumferential surface of the hinge shaft of the switch door 4 is fixedly connected with a rotation damper 7, and the rotation damper 7 is fixedly connected to the upper end of the mounting box 1. When the switch door 4 is opened to repair the voltage regulating and stabilizing component 3, the switch door 4 is prone to swing and collide at will. At this time, the rotation of the switch door 4 is damped by the rotation damper 7, so that the switch door 4 will not swing at will and the rotation is more stable. The switch door 4 is connected to the upper end of the mounting box 1 through a mounting frame. For the staff in this technical field, the switch door 4 is a prior art and will not be described in detail here.

[0026] When the utility model is in use, when the voltage regulating and stabilizing component 3 of the device needs to be maintained and repaired, the three-phase asynchronous motor 5012 is first manually started, so that the three-phase asynchronous motor 5012 drives the worm 5013 to rotate, the worm 5013 drives the worm wheel 5014 to rotate, and the worm wheel 5014 drives one of the lead screws 5011 to rotate. When the lead screw 5011 rotates, it drives the synchronous pulley 5021 to rotate. The synchronous pulley 5021 makes the two lead screws 5011 rotate synchronously through the synchronous transmission belt 5022. At this time, the two lead screws 50 11 rotates simultaneously, driving the mounting platform 2 to extend out of the mounting box 1, and then the three-phase asynchronous motor 5012 is manually turned off. At this time, the voltage regulating and stabilizing component 3 on the upper side of the mounting platform 2 can be maintained and repaired. When the maintenance is completed, the three-phase asynchronous motor 5012 is manually turned on to reverse, so that the worm 5013 and the worm wheel 5014 are reversed, and the two lead screws 5011 are driven to reverse through the synchronous transmission component 502, and the mounting platform 2 is retracted into the mounting box 1, and the three-phase asynchronous motor 5012 is manually turned off. At this time, the switch door 4 is closed to complete the installation and maintenance.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
