Description

Technical Field

[0001] The present invention relates to the field of power quality regulators, and particularly to a mounting seat for a power quality regulator. Background Art

[0002] The UPQC, whose full name is Unified Power Quality Conditioner, is a device with comprehensive power quality regulation functions and an important representative in the active filter family. It combines a series active filter and a shunt active filter, so as to give full play to the advantages of the series and shunt active filters in power system applications and have comprehensive power quality regulation functions. In actual use, the UPQC is not used alone, but multiple devices cooperate with each other. During the use process, a large amount of heat is often generated. At present, the more ideal heat dissipation method is to immerse the whole device in an insulating solution for efficient heat dissipation through the liquid. However, in the implementation process, due to the large volume of the device, it takes a lot of time for each liquid discharge and injection. Moreover, when the device is normally overhauled and maintained, draining the liquid increases the maintenance cost. At present, most of the operations are to lift the device out of the liquid level for liquid discharge and injection, but direct lifting is likely to damage the wire harness and connectors. Summary of the Invention

[0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and perfect the existing technical solution, and provide a mounting seat for a power quality regulator, aiming to save maintenance time and avoid damage to the cable connectors caused by lifting the regulator. To this end, the present invention adopts the following technical solutions.

[0004] A power quality regulator mounting seat, comprising a base, a regulator mounting seat plate, a lifting mechanism, a lifting guiding mechanism and a wire arranging mechanism. The lifting mechanism is arranged in the middle above the base. The lifting guiding mechanism is arranged on the front and rear sides of the base. The wire arranging mechanism is arranged on the base and on the left side of the lifting mechanism. The upper end of the lifting mechanism is fixedly connected to the regulator mounting seat plate to lift or lower the height of the regulator mounting seat plate. The upper end of the lifting guiding mechanism is fixedly connected to the regulator mounting seat plate. The wire arranging mechanism includes a cable compensation triggering module and a guiding roller. A groove with an open end and a top surface is provided at the left end of the base. The guiding roller is arranged in the groove, and its axial direction is front and rear. A cable guiding channel is provided between the guiding roller and the bottom surface and side surface of the groove. The guiding roller is connected with a driving device. The cable compensation triggering module includes a support plate, a wire gathering plate, an auxiliary plate and a pressure sensor. The support plate is vertically connected to the base in the front and rear direction. The wire gathering plate is arranged on the left side of the support plate. The auxiliary plate is arranged on the right side of the support plate. The wire gathering plate and the auxiliary plate are fixedly connected by two horizontal left and right sliding rods, and the sliding rods are slidably matched with the support plate. The cable of the regulator passes through the cable guiding channel below the guiding roller and then vertically passes through the channel surrounded by the two sliding rods, the support plate and the wire gathering plate, and then is connected to the regulator. The pressure sensor is arranged on the auxiliary plate, and the force sensing position of the pressure sensor faces the right side surface of the support plate. The pressure sensor is connected to the driving device of the guiding roller.

[0005] The regulator is installed on the regulator mounting seat plate. The cable of the regulator passes through the cable guiding channel and then through the channel between the support plate and the wire gathering plate and is connected to the regulator. When the lifting mechanism drives the regulator mounting seat plate to lift upward, the cable of the regulator moves upward. The movement of the cable will press the wire gathering plate in contact with it to move to the left, and cause the pressure sensor to move to the left. When the pressure sensor presses against the support plate and reaches the set value, it means that the cable is relatively tight and the length is insufficient at this time. Continuing to lift will cause the joint to break off. At this time, the generated pressure signal is transmitted to the driving device of the guiding roller. The driving device makes a reaction, and the lifting mechanism stops lifting. The driving device drives the guiding roller to rotate, driving the cable to move upward, gathering the excess cable of the regulator immersed in the insulating oil, so that the cable makes an active compensatory lift. The lifting guiding mechanism can ensure the smoothness of the lift, avoiding the disadvantages of the traditional need to drain the oil in the room before maintenance, saving a large amount of maintenance time, reducing the high maintenance cost caused by liquid discharge, and avoiding damage or loosening of the cable and joint parts due to excessive tension when the regulator is lifted through the active cable compensation lift.

[0006] As a preferred technical means: The side surface and the bottom surface of the groove are arc-transitioned, and the top edge line of the groove is arc-transitioned. The arc transition can avoid damage to the cable caused by acute angles.

[0007] As a preferred technical means: the outer contour radius of the guiding roller is greater than the bendable radius of the cable. This can effectively prevent the cable from being bent beyond its bendable radius at the corner, thus avoiding cable damage.

[0008] As a preferred technical means: the guiding roller includes a shaft rod and a compensating wheel sleeved on the shaft rod. One end of the shaft rod is connected to the driving device, and the other end is rotatably connected to the base. The compensating wheel is made of a flexible material. The structure is simple, and using a flexible material can better avoid damaging the cable.

[0009] As a preferred technical means: the lifting mechanism includes a lifting rod, a worm and worm gear driving device, and a power device. The lifting rod is arranged vertically. The top end of the lifting rod is fixedly connected to the regulator mounting seat plate through a connecting seat. The worm and worm gear driving device includes a housing, a worm gear and a worm. The worm gear and the worm are arranged inside the housing. The lifting rod vertically passes through the worm and worm gear driving device. The worm gear is sleeved on the lifting rod and is matched with the lifting rod through threads. The worm is arranged horizontally and is meshed with the worm gear. The worm is connected to the power device. This can effectively achieve lifting drive.

[0010] As a preferred technical means: a vertical through hole that is slidably matched with the lifting rod is provided on the base. On the one hand, it can guide and support the lifting rod, and the lifting rod has good stability. In addition, it can also effectively reduce the overall height of the lifting mechanism.

[0011] As a preferred technical means: the lifting guiding mechanism includes 4 sets of guiding components, with 2 sets provided on each of the front side and the rear side of the base. Each set of guiding components includes a guiding base, a guiding sleeve and a guiding column. The guiding base is fixed on the side of the base. The guiding sleeve is arranged vertically, and the lower end is fixedly connected to the guiding base. The guiding column is slidably matched with the guiding sleeve, and the upper end of the guiding column is fixedly connected to the regulator mounting seat plate. The distribution is balanced, the structure is simple, and the guiding stability is good.

[0012] As a preferred technical means: the four corners of the regulator mounting seat plate are in arc transition. Avoiding sharp angles can effectively improve the safety during operation.

[0013] Beneficial effects: The cable arranging mechanism can gather the excess cables of the regulator immersed in the insulating oil, so as to make compensation for the cable lifting. The lifting guiding mechanism can ensure the smoothness of the lifting, avoiding the drawback of the traditional method that requires draining the oil in the room before maintenance. It can save a large amount of maintenance time and reduce the relatively high maintenance cost caused by draining the liquid. Through the active cable compensation and lifting, when the regulator is lifted, the damage or loosening of the cable and the joint part caused by excessive tension can be avoided.

Detailed implementation manners

[0019] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings of the specification.

[0020] As Figures 1-4As shown in the figure, a power quality regulator mounting seat includes a base 1, a regulator mounting seat plate 2, a lifting mechanism 3, a lifting guiding mechanism 4, and a wire arranging mechanism. The lifting mechanism 3 is arranged in the middle above the base 1. The lifting guiding mechanism 4 is arranged on the front and rear sides of the base 1. The wire arranging mechanism is arranged on the base 1 and on the left side of the lifting mechanism 3. The upper end of the lifting mechanism 3 is fixedly connected to the regulator mounting seat plate 2 to lift or lower the height of the regulator mounting seat plate 2. The upper end of the lifting guiding mechanism 4 is fixedly connected to the regulator mounting seat plate 2. The wire arranging mechanism includes a cable compensation trigger module 5 and a guiding roller 6. A groove 101 with an open end and top surface is provided at the left end of the base 1. The guiding roller 6 is arranged in the groove 101, and its axial direction is front-rear. A cable guiding channel 102 is provided between the guiding roller 6 and the bottom and side surfaces of the groove 101. The guiding roller 6 is connected to a driving device. The cable compensation trigger module 5 includes a support plate 501, a wire gathering plate 502, an auxiliary plate 503, and a pressure sensor 504. The support plate 501 is vertically connected to the base 1 in the front-rear direction. The wire gathering plate 502 is arranged on the left side of the support plate 501. The auxiliary plate 503 is arranged on the right side of the support plate 501. The wire gathering plate 502 and the auxiliary plate 503 are fixedly connected by two horizontal left-right sliding rods 505, and the sliding rods 505 are slidably matched with the support plate 501. The cable of the regulator passes through the cable guiding channel 102 below the guiding roller 6 and then vertically passes through the channel surrounded by the two sliding rods 505, the support plate 501, and the wire gathering plate 502, and then is connected to the regulator. The pressure sensor 504 is arranged on the auxiliary plate 503, and the force sensing position of the pressure sensor 504 faces the right side surface of the support plate 501. The pressure sensor 504 is connected to the driving device of the guiding roller 6.

[0021] To avoid damage to the cable caused by acute angles, the side surface and the bottom surface of the groove 101 are in arc transition, and the top edge line of the groove 101 is in arc transition. The arc transition can avoid damage to the cable caused by acute angles.

[0022] To avoid damage to the cable due to excessive bending, the outer contour radius of the guiding roller 6 is greater than the bendable radius of the cable. This can effectively avoid the cable from being bent beyond its bendable radius at the corner and avoid cable damage.

[0023] As a preferred technical measure: The guiding roller 6 includes a shaft rod 601 and a compensation wheel 602 sleeved on the shaft rod 601. One end of the shaft rod 601 is connected to the driving device, and the other end is rotatably connected to the base 1. The compensation wheel 602 is made of a flexible material. The structure is simple, and using a flexible material can better avoid damage to the cable.

[0024] In order to achieve lifting drive, the lifting mechanism 3 includes a lifting rod 301, a worm and worm gear drive device, and a power device. The lifting rod 301 is vertically arranged. The top end of the lifting rod 301 is fixedly connected to the regulator mounting seat plate 2 through a connecting seat 302. The worm and worm gear drive device includes a housing 303, a worm gear 304 and a worm 305. The worm gear 304 and the worm 305 are arranged inside the housing 303. The lifting rod 301 vertically passes through the worm and worm gear drive device. The worm gear 304 is sleeved on the lifting rod 301 and is matched with the lifting rod 301 through threads. The worm is horizontally arranged and is meshed and connected to the worm gear 304. The worm 305 is connected to the power device. Lifting drive can be effectively achieved.

[0025] In order to reduce the overall height of the lifting mechanism 3, a vertical through hole 103 that is slidably matched with the lifting rod 301 is provided on the base 1. On the one hand, it can serve as the guiding support for the lifting rod 301, and the lifting rod 301 has good stability. In addition, the overall height of the lifting mechanism 3 can be effectively reduced.

[0026] In order to achieve reliable guiding stability, the lifting guiding mechanism 4 includes 4 sets of guiding components, with 2 sets provided on each of the front side and the rear side of the base 1. Each set of guiding components includes a guiding base 401, a guiding sleeve 402 and a guiding column 403. The guiding base 401 is fixed to the side of the base 1. The guiding sleeve 402 is vertically arranged, and the lower end is fixedly connected to the guiding base 401. The guiding column 403 is slidably matched with the guiding sleeve 402, and the upper end of the guiding column 403 is fixedly connected to the regulator mounting seat plate 2. The distribution is balanced, the structure is simple, the guiding stability is good, and the reliability is high.

[0027] In order to avoid contact injuries, the four corners of the regulator mounting seat plate 2 are transitioned with arcs. Avoiding sharp angles can effectively improve the safety during operation and avoid contact injuries.

[0028] The regulator is installed on the regulator mounting plate 2. The cable of the regulator passes through the cable guiding channel 102, and then passes through the channel between the support plate 501 and the wire gathering plate 502 and is connected to the regulator. When the lifting mechanism 3 drives the regulator mounting plate 2 to lift upward, the cable of the regulator moves upward. The movement of the cable will press the wire gathering plate 502 in contact with it to move to the left, and cause the pressure sensor 504 to move to the left. When the pressure sensor 504 presses against the support plate 501 and reaches the set value, it indicates that the cable is relatively tight and the length is insufficient at this time. Continuing to lift will cause the joint to disengage. At this time, the generated pressure signal is transmitted to the driving device of the guiding roller 6, and the driving device makes a reaction, and the lifting mechanism 3 stops lifting. The driving device drives the guiding roller 6 to rotate, driving the cable to move upward, gathering the excess cable of the regulator immersed in the insulating oil, so that the cable makes an active compensatory lift. The lifting guiding mechanism 4 can ensure the smoothness of the lift, avoiding the disadvantages of the traditional need to drain the oil in the room before maintenance, saving a large amount of maintenance time and reducing the high maintenance cost caused by liquid discharge. Through the active cable compensatory lift, when the regulator is lifted, damage or loosening of the cable and the joint part caused by excessive tension are avoided.

[0029] In this embodiment, the driving devices of the guiding roller 6 and the power device of the lifting mechanism 3 both adopt servo motors.

[0030] The above Figures 1-4 The shown power quality regulator mounting is a specific embodiment of the present invention, which has already reflected the substantial features and progress of the present invention. According to the actual use needs, under the inspiration of the present invention, equivalent modifications can be made to its shape, structure, etc., and all are within the protection scope of this solution.
