Description

Technical Field

[0001] The present invention relates to the technical field of power quality monitors, and in particular to a power data quality monitor based on power big data. Background Art

[0002] In modern power systems, with the diversification of factors such as the connection of new energy sources to the grid and load changes, power quality issues have become increasingly prominent, which has had an important impact on the safe operation of the power grid and users' electrical equipment. Therefore, the development of an efficient power data quality monitor has become one of the key tasks to ensure the quality of power supply.

[0003] From a technical perspective, existing power data quality monitors usually use high-performance processors, such as ARM9, combined with embedded operating systems, expandable memory, and a wealth of peripheral interfaces. These monitors can collect a variety of power quality parameters including voltage, current, frequency, etc., and achieve accurate measurement of these parameters through signal conditioning circuits, A / D conversion and other processes. For example, the use of the MAX1324 chip can achieve 8-channel synchronous sampling, effectively improving the accuracy and speed of data acquisition. In addition, with the help of edge computing, power big data and cloud computing technologies, power data quality monitors can achieve distributed storage and processing of data, improving data processing efficiency and reliability.

[0004] Since these monitoring tasks involve high-load power loads and various nonlinear loads, such as electric locomotives and arc furnaces in electrified railways, these devices will generate a lot of heat during use, causing the power quality monitor to generate a certain amount of heat during operation. In order to ensure the normal use and safety of the instrument in a high temperature environment, special attention should be paid to the heat dissipation problem.

[0005] The power data quality monitors in the prior art are mostly ventilated and heat-dissipated by opening heat dissipation ports on both sides, and the power data quality monitors themselves are often installed in cabinets such as switch cabinets or distribution cabinets. Therefore, when the monitor is ventilated and heat-dissipated through the heat dissipation ports on both sides, the gas inside the monitor is mostly circulated with the gas in the cabinet. However, there may often be many other electrical equipment in the cabinet where the monitor is installed. In this case, heat will also be generated during the operation of other electrical equipment, and the temperature in the cabinet is usually high. Therefore, when the monitor circulates and dissipates heat with the gas in the cabinet, it cannot achieve the effect of efficient heat dissipation, and the heat dissipation effect is poor. If the monitor cannot obtain effective heat dissipation for a long time, the high temperature will easily affect its service life and performance. There are certain defects that need to be improved. Summary of the invention

[0006] The purpose of the present invention is to provide a power data quality monitor based on power big data to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an electric power data quality monitor based on electric power big data, comprising a monitor body, both sides of the monitor body are provided with ventilation and heat dissipation mechanisms for ventilating and dissipating the inner cavity of the monitor body, the ventilation and heat dissipation mechanism comprises a retractable corrugated ventilation pipe fixedly connected to the monitor body, the other end of the retractable corrugated ventilation pipe is fixedly connected to a wind tube through a flange, a ventilation component is arranged inside the wind tube, and one end of the wind tube away from the retractable corrugated ventilation pipe is fixedly connected to a dust filter plate, a cleaning component is arranged on the dust filter plate, and the cleaning component is used to clean the dust adsorbed on the dust filter plate;

[0008] In actual application, through the setting of two sets of ventilation and heat dissipation mechanisms, the inner cavity of the monitor body is connected with the environment outside the cabinet, so that although the monitor body is installed in the cabinet, it can still be directly ventilated and cooled with the external environmental gas, avoiding the monitor body and the gas in the cabinet from being ventilated and cooled, and the heat dissipation efficiency being affected by the high temperature generated by the operation of other equipment in the cabinet, which greatly improves the heat dissipation effect of the monitor body, ensures the efficient operation of the monitor body, and effectively improves the service life and performance of the monitor body.

[0009] As a further description of the above technical solution: the ventilation component includes a frame fixedly mounted on the inner wall of the wind tube, a motor is fixedly mounted on the frame, an output end of the motor is fixedly connected to a rotating shaft, and an outer surface of the rotating shaft is fixedly sleeved with ventilation fan blades.

[0011] As a further description of the above technical solution: one end of the movable shaft located inside the wind tube is fixedly connected to a fixed ring and a driven gear plate, the side of the fixed ring close to the dust filter plate is fixedly connected to a return spring 1, the other end of the return spring 1 is fixedly connected to a movable ring, the movable ring is movably sleeved on the outer surface of the movable shaft, and a plurality of balls are rollingly embedded in the side of the movable ring close to the dust filter plate.

[0013] As a further description of the above technical solution: air storage frames are fixedly connected to both sides of the rotating rod.

[0014] As a further description of the above technical solution: the elastic limit pin includes a limit pin that movably passes through the rotating rod, one end of the limit pin is movably inserted in the pin hole, and the other end of the limit pin is fixedly connected to a pull block, and a reset spring 2 is arranged between the pull block and the rotating rod and on the outer surface of the limit pin.

[0015] As a further description of the above technical solution: a display screen, indicator lights and control buttons are arranged on the front of the monitoring instrument body.

[0016] As a further description of the above technical solution: a plurality of connection ports are arranged on the back of the monitoring instrument body.

[0017] The present invention has the following beneficial effects:

[0018] 1. Through the setting of two sets of ventilation and heat dissipation mechanisms, the inner cavity of the monitor body is connected with the environment outside the cabinet, so that although the monitor body is installed in the cabinet, it can still be directly ventilated and cooled with the external environmental gas, avoiding the monitor body and the gas in the cabinet from being ventilated and cooled, and the heat dissipation efficiency is affected by the high temperature generated by the operation of other equipment in the cabinet, which greatly improves the heat dissipation effect of the monitor body, ensures the efficient operation of the monitor body, and effectively improves the service life and performance of the monitor body.

[0019] 2. When the ventilation and heat dissipation mechanism is just turned on, the speed of the motor output shaft is low, so that the ventilation fan blades and the active gear disc rotate synchronously at a low speed, and drive the driven gear disc meshing with the active gear disc to rotate, and then drive the movable shaft, rotating rod and cleaning brush to rotate. The rotating cleaning brush can clean the dust impurities adsorbed on the surface of the dust filter plate, and the blowing force generated by the rotation of the ventilation fan blades can blow away the dust impurities removed by the brush, avoiding the dust impurities from being sucked back onto the dust filter plate again, thereby ensuring efficient dust removal and cleaning of the dust filter plate.

[0020] 3. When the ventilation and heat dissipation mechanism is turned on for a period of time, the speed of the shaft will continue to increase until it reaches the preset speed. At the same time, the speed of the ventilation fan blades will also increase accordingly, and the blowing force generated will also increase at the same time. The larger wind force acts on the air storage frame, pushing the air storage frame to overcome the elastic force of the return spring 1 and move to the side away from the dust filter plate, and drive the driven gear disc to move so that it disengages from the active gear disc and releases the meshing relationship. At this time, the rotation of the active gear disc cannot drive the cleaning component to run, avoiding the long-term operation of the cleaning component. It can not only avoid the cleaning brush from long-term relative movement and friction with the dust filter plate to accelerate wear, but also reduce the load on the motor during movement and reduce energy consumption.

[0021] 4. The coordinated use of the elastic limit pin and the pin hole can facilitate the staff to disassemble and assemble the rotating rod, thereby facilitating the staff to clean, maintain or replace the cleaning brush. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As attached Figure 1 To Attachment Fig. 9 As shown:

[0035] Embodiment 1: The present invention provides an electric power data quality monitor based on electric power big data, comprising a monitor body 1, both sides of the monitor body 1 are provided with ventilation and heat dissipation mechanisms for ventilating and dissipating the inner cavity of the monitor body 1, the ventilation and heat dissipation mechanism comprises a retractable corrugated ventilation pipe 2 fixedly connected to the monitor body 1, the other end of the retractable corrugated ventilation pipe 2 is fixedly connected to a wind tube 3 through a flange, a ventilation component 4 is arranged inside the wind tube 3, and the end of the wind tube 3 away from the retractable corrugated ventilation pipe 2 is fixedly connected to a dust filter plate 5, a cleaning component 6 is arranged on the dust filter plate 5, and the cleaning component 6 is used to clean the dust adsorbed on the dust filter plate 5;

[0036] The monitor body 1 adopts the power data quality monitor in the prior art, and the retractable corrugated ventilation pipe 2 is fixedly installed at the heat dissipation port positions on both sides of the power data quality monitor in the prior art. The retractable corrugated ventilation pipe 2 is connected to the inner cavity of the monitor through the original heat dissipation port on the monitor, thereby ensuring that the monitor body 1 installed in the cabinet and the external environment of the cabinet are ventilated and cooled without changing the structure and principle of the existing monitor.

[0037] The ventilation assembly 4 includes a frame 401 fixedly mounted on the inner wall of the air duct 3, a motor 402 is fixedly mounted on the frame 401, a rotating shaft 403 is fixedly connected to the output end of the motor 402, and a ventilation fan blade 404 is fixedly sleeved on the outer surface of the rotating shaft 403;

[0038] The cleaning assembly 6 includes a movable shaft 601 movably installed at the middle position of the dust filter plate 5, a positioning groove 602 is provided at one end of the movable shaft 601 located outside the wind tube 3, a positioning block 603 is movably inserted inside the positioning groove 602, a rotating rod 604 is fixedly connected to the outer surface of the positioning block 603, an elastic limiting latch 605 is provided on the top of the rotating rod 604, a pin hole 606 is provided on the movable shaft 601 and at a position corresponding to the elastic limiting latch 605, a cleaning brush 607 is fixedly connected to the side of the rotating rod 604 close to the dust filter plate 5, and the movable shaft 601 is located inside the wind tube 3. One end of the part is fixedly connected with a fixed ring 608 and a driven toothed disc 609, the fixed ring 608 is fixedly connected with a return spring 6010 on one side close to the dust filter plate 5, the other end of the return spring 6010 is fixedly connected with a movable ring 6011, the movable ring 6011 is movably sleeved on the outer surface of the movable shaft 601, and a plurality of balls 6012 are rollingly embedded on the side of the movable ring 6011 close to the dust filter plate 5, the driven toothed disc 609 is meshed with a driving toothed disc 6013, and the driving toothed disc 6013 is fixedly installed on the rotating shaft 403, and both sides of the rotating rod 604 are fixedly connected with air storage frames 6014;

[0039] When the ventilation and heat dissipation mechanism is just turned on, the speed of the output shaft of the motor 402 is relatively low, so that the ventilation fan blades 404 and the active gear disc 6013 rotate synchronously at a low speed, and drive the driven gear disc 609 meshing with the active gear disc 6013 to rotate, thereby driving the movable shaft 601, the rotating rod 604 and the cleaning brush 607 to rotate, and the dust impurities adsorbed on the surface of the dust filter plate 5 can be cleaned by the rotating cleaning brush 607, and the blowing force generated by the rotation of the ventilation fan blades 404 can blow away the dust impurities brushed off, avoiding the dust impurities being sucked back onto the dust filter plate 5 again, thereby ensuring efficient dust removal and cleaning of the dust filter plate 5;

[0040] When the ventilation and heat dissipation mechanism is turned on for a period of time, the rotation speed of the rotating shaft 403 will continue to increase until it reaches the preset rotation speed. At the same time, the rotation speed of the ventilation fan blades 404 will also increase accordingly, and the blowing force generated will also increase at the same time. The larger wind force acts on the air storage frame 6014, pushing the air storage frame 6014 to overcome the elastic force of the return spring 6010 and move to the side away from the dust filter plate 5, and drive the driven gear disc 609 to move so that it disengages from the active gear disc 6013 and releases the meshing relationship. At this time, the rotation of the active gear disc 6013 cannot drive the cleaning component 6 to operate, thereby avoiding the cleaning component 6 from running for a long time. It can not only avoid the cleaning brush 607 from long-term relative movement and friction with the dust filter plate 5 to accelerate wear, but also reduce the load of the motor 402 during movement, thereby reducing energy consumption.

[0041] The front of the monitoring instrument body 1 is provided with a display screen 7 , an indicator light 8 and a control button 9 , and the back of the monitoring instrument body 1 is provided with a plurality of connection ports 10 .

[0042] Working principle: When in use, the staff first installs the monitor body 1 at a suitable position on a cabinet such as a control cabinet or a switch cabinet according to the installation specifications of the power data quality monitor, and then embeds and installs the two air ducts 3 on the cabinet so that the air ducts 3 are connected to the external environment of the cabinet;

[0043] When the monitor body 1 is in operation, the inside of the monitor body 1 is ventilated and cooled by alternating operation of the two sets of ventilation and heat dissipation mechanisms. When one set of ventilation and heat dissipation mechanisms is in operation, the motor 402 in the ventilation and heat dissipation mechanism runs, driving the rotating shaft 403 to rotate synchronously, and then driving the ventilation fan blades 404 to rotate, so that the gas in the wind tube 3 is blown to the external environment, and the wind tube 3 is connected to the inner cavity of the monitor body 1 through the retractable corrugated ventilation pipe 2, and then after the gas in the wind tube 3 is blown out by the ventilation fan blades 404, a certain negative pressure is generated inside the wind tube 3, and at the same time, the inner cavity of the monitor body 1 is in a negative pressure state. Thus, through the cooperation of the retractable corrugated ventilation pipe 2 and the air cylinder 3 in another set of ventilation and heat dissipation mechanisms in the shutdown state, the gas in the external environment is sucked into the monitor body 1 after filtering the dust on the dust filter plate 5, so that although the monitor body 1 is installed in the cabinet, it can still be directly ventilated and cooled with the external environment gas, avoiding the monitor body 1 and the gas in the cabinet being ventilated and cooled, and the heat dissipation efficiency being affected by the high temperature generated by the operation of other equipment in the cabinet, which greatly improves the heat dissipation effect of the monitor body 1, ensures the efficient operation of the monitor body 1, and effectively improves the service life and performance of the monitor body 1;

[0044] The dust filter plate 5 filters and intercepts dust in the external air, preventing dust from entering the monitor body 1, thereby protecting the monitor body 1 and preventing the monitor body 1 from being affected by dust accumulation.

[0045] During the alternating operation of the two ventilation and heat dissipation mechanisms, when the ventilation and heat dissipation mechanisms are just turned on, the rotation speed of the shaft 403 is relatively low when the motor 402 is just started, and the rotation of the shaft 403 drives the ventilation fan blades 404 and the active gear disc 6013 to rotate synchronously at a low speed. The low-speed rotation of the ventilation fan blades 404 produces a relatively small blowing force. At the same time, the active gear disc 6013 drives the driven gear disc 609 meshing therewith to rotate, thereby driving the movable shaft 601 and the rotating rod 604 to rotate synchronously, and drives the cleaning brush 607 to rotate. The rotating cleaning brush 607 can clean the dust impurities adsorbed on the surface of the dust filter plate 5, and the blowing force generated by the rotation of the ventilation fan blades 404 can blow away the dust impurities brushed out, preventing the dust impurities from being sucked back onto the dust filter plate 5 again, thereby ensuring efficient dust removal and cleaning of the dust filter plate 5.

[0046] As the motor 402 is turned on for a longer time, the speed of the rotating shaft 403 will continue to increase until it reaches the preset speed. At the same time, the speed of the ventilation fan blades 404 will also increase accordingly, and the blowing force generated will also increase at the same time. The larger wind force acts on the air storage frame 6014 and overcomes the elastic force of the return spring 6010, pushing the air storage frame 6014 to move to the side away from the dust filter plate 5, and driving the movable shaft 601, the fixed ring 608 and the driven gear plate 609 to move synchronously. The fixed ring 608 moves to squeeze the return spring 6010 to put it in a compressed state and store energy, and the driven gear plate 609 moves to disengage and release the meshing relationship with the active gear plate 6013. At this time, the rotation of the active gear plate 6013 cannot drive the cleaning component 6 to operate, thereby avoiding the cleaning component 6 from running for a long time. It can not only avoid the cleaning brush 607 from rubbing against the dust filter plate 5 for a long time and accelerating wear, but also reduce the load of the motor 402 during movement and reduce energy consumption.

[0047] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that the elastic limit pin 605 includes a limit pin 6051 movably passing through the rotating rod 604, one end of the limit pin 6051 is movably inserted in the pin hole 606, and the other end of the limit pin 6051 is fixedly connected with a pull block 6052, and a return spring 2 6053 is provided between the pull block 6052 and the rotating rod 604 and on the outer surface of the limit pin 6051.

[0048] When the cleaning brush 607 needs to be cleaned, maintained or replaced after being used for a period of time, the staff member holds the pull block 6052 and pulls it to the side away from the rotating rod 604, so that the reset spring 6053 is deformed and stores energy, and the movement of the pull block 6052 drives the limit pin to move synchronously until the limit pin completely exits the pin hole 606, releasing the limit fixation of the rotating rod 604, and then the staff member moves the rotating rod 604 to the side away from the dust filter plate 5, so that the positioning block 603 exits The positioning groove 602 can realize the removal of the cleaning brush 607 from the movable shaft 601. Conversely, the positioning block 603 on the rotating rod 604 is inserted into the positioning groove 602, and the limit pin of the rotating rod 604 is positioned opposite to the pin hole 606 on the movable shaft 601. Then the pull block 6052 is released, and the elastic force of the reset spring 2 6053 drives the limit pin to be embedded in the pin hole 606, so that the rotating rod 604 is limited and fixed, thereby realizing the installation of the cleaning brush 607.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
