Description

Technical Field

[0001] The present invention relates to the technical field of power losses in distribution networks, and specifically to a portable power loss monitoring device for distribution networks. Background Art

[0002] ‌Power losses in distribution networks‌ refer to the electrical energy losses generated in the distribution link during the process of transmitting electrical energy from power plants to users. These losses mainly include transformer losses, impedance losses of busbars and connection points, electromagnetic radiation losses, etc.

[0003] A power loss monitoring device for distribution networks is a device used to monitor in real time the power loss situation in a distribution network (a power network that receives electrical energy from a transmission network or a regional power plant and distributes it locally or step by voltage levels to various users). It can accurately measure, record, and analyze the power losses in the distribution network during the process of electrical energy transmission and distribution, including various losses such as line losses and transformer losses.

[0004] For example, for the power loss monitoring device with the application number 202322597942.X, by respectively fixing a clamping component on two wires at the upper end of a current meter, and setting an upper clamping block and a lower clamping block that can approach each other in the clamping component, the fixation between power grid wires is achieved; and by setting a connecting component between the two clamping components and setting a connecting rod between the connecting component and the current meter, the fixation between the current meter and the sleeve is achieved, so that the wire is no longer stressed, avoiding damage to the wire caused by long-term tension during long-term monitoring. However, its device still has certain defects;

[0005] When using the power loss monitoring device for a long time, the display screen of the flow meter will accumulate a lot of dust, which is not convenient for observing the content on the display screen. When cleaning the dust on the display screen, it is necessary to find cleaning components locally to clean it, so it is relatively inconvenient to clean the display screen due to humidity. At the same time, the connecting rod on the current meter is relatively long, which is not convenient for storing it, and the device occupies a large area when it is idle.

[0006] Therefore, we propose a portable power loss monitoring device for distribution networks to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of the present invention is to provide a portable power loss monitoring device for a distribution network, so as to solve the problems raised in the above background technology. When the power loss monitoring device is used for a long time in the current market, a large amount of dust will accumulate on the display screen of the flowmeter, which is not convenient for observing the content on the display screen. When cleaning the dust on the display screen, it is necessary to find cleaning components locally to clean it, so it is relatively inconvenient to clean the display screen due to humidity. At the same time, the connecting rod on the ammeter is relatively long, which is not convenient for storing it, and the device occupies a large area when it is idle.

[0008] To achieve the above purpose, the present invention provides the following technical solutions: A portable power loss monitoring device for a distribution network, including a power loss monitoring flowmeter. A display screen is installed on the front surface of the power loss monitoring flowmeter, and connecting components are installed on both the upper left and right sides of the power loss monitoring flowmeter.

A fixed ball is installed at the upper end of the connecting column, and through grooves are opened on the fixed balls. A connecting plate is installed on the hollow column;

[0009] Connecting strips are installed on both the left and right sides of the connecting plate, and positioning grooves are opened on the reverse sides below the connecting strips. Side fixing blocks are installed on both the left and right sides of the power loss monitoring flowmeter, and plugging grooves are opened above the side fixing blocks. Rotating shaft components are installed on the reverse sides of the side fixing blocks, and movable plates are installed on the rotating shaft components. Movable bolts are installed on the movable plates, and limiting rings are installed on the movable bolts. A rectangular groove and a circular groove are opened on the reverse sides of the side fixing blocks. Guide rods are installed on the reverse sides of the side fixing blocks, movable strips are sleeved on the guide rods, and a baffle component is installed below the movable strips;

[0010] A rectangular block and a placement box are installed on the left side of the power loss monitoring flowmeter. A first chute is opened on the upper surface of the placement box. A second chute is opened on the inner side of the placement box close to the power loss monitoring flowmeter. A scraping plate is installed on the inner side of the placement box far from the power loss monitoring flowmeter. A cleaning cloth is arranged inside the placement box, and the cleaning cloth is connected to a support plate through a magic tape component. A support block is installed above the support plate, and a column is installed above the support block. A threaded sleeve component is installed on the rectangular block.

[0011] Preferably, the hollow column is fixedly connected to the monitoring wire, the hollow column is fixedly connected to the connecting plate, and the interiors of the hollow column and the connecting column are both designed with a conductive structure.

[0012] With the above structural design, after the cable on the measured distribution network is fixed in the fixed ball, the current signal on the cable is transmitted to the power loss monitoring flowmeter through the connecting column, the hollow column and the monitoring wire to monitor the power loss of the cable.

[0013] Preferably, a heat dissipation hole is provided on the fixing ball, a fixing bolt is installed on the upper end of the fixing ball, and an abutment block is installed on the lower end of the fixing bolt, and the diameter of the through groove is larger than the diameter of the power grid cable.

[0014] With the above structural design, the cable on the distribution network to be tested is passed through the through slot on the fixing ball, and then the fixing bolt is rotated, and the fixing bolt drives the abutment block to move downward to fix the cable.

[0015] Preferably, a plurality of heat dissipation holes are provided, and the abutment blocks are designed to be circular in structure. The abutment blocks are circular and located in the through grooves, and anti-slip protrusions are provided on the lower surfaces of the abutment blocks.

[0016] With the above structural design, the heat dissipation holes on the fixed ball are conducive to the heat dissipation of the cables inside the fixed ball, preventing short circuit caused by high cable temperature due to long-term monitoring.

[0017] Preferably, the connecting plate is located directly above the power loss monitoring flow meter, and an insulating sleeve is installed on the connecting plate.

[0018] With the above structural design, the portable power loss monitoring flow meter can be easily connected through the insulating sleeve on the connecting plate, making it more convenient to carry.

[0019] Preferably, the connecting strip is slidably connected to the plug-in slot, the movable plate is rotationally connected to the rotating shaft assembly, and an indicator line is provided on the connecting strip.

[0020] With the above structural design, the connecting strip can move up and down along the plug-in slot when subjected to force, so it is more stable when the connecting strip is extended and stored, so that the connecting strip will not deviate.

[0021] Preferably, when the connecting strip moves to the inner bottom of the side fixing block, the center line of the circular groove on the side fixing block and the center line of the positioning groove on the connecting strip coincide with each other.

[0022] With the above-mentioned structural design, when storing the connecting strip, the movable strip and the baffle assembly are pushed to abut against the side fixed block, and then the movable plate is rotated to a downward vertical state, and then the movable bolt on the movable plate is rotated until its end abuts against the positioning groove on the connecting strip, thereby completing the fixation of the connecting strip.

[0023] Preferably, the movable bar is slidably connected to the guide rod, a limit block is provided at the outer end of the guide rod, and the baffle assembly is slidably connected to the rectangular groove.

[0024] With the above structural design, when it is necessary to measure the electrical loss, move the connecting bar upward to the position of the indicating line, then rotate the movable plate to the vertically upward state, and then rotate the movable bolt on the movable plate. When the movable bolt moves towards the connecting bar, it drives the limit ring on the movable bolt to move towards the connecting bar. The limit ring drives the movable bar and the baffle assembly to move towards the connecting bar, so that the baffle assembly moves below the connecting bar to support the connecting bar. At the same time, the movable bolt moves into the positioning groove on the connecting bar, thus completing the limitation of the connecting bar, making the extension of the connecting bar more stable, facilitating the increase of the distance between the fixed ball and the power loss monitoring flowmeter, facilitating the monitoring of the electrical loss of the distribution network, and preventing the influence of the line components in the distribution box due to too close distance, which is inconvenient to operate.

[0025] Preferably, two scraping plates are provided. A plurality of through holes are formed in the scraping plates, and the scraping plates are located at the middle position in the placement box. The scraping plates are in contact with the cleaning cloth surface. The magic tape assembly is fixed on the support plate. The surface of the cleaning cloth in contact with the magic tape assembly is a hairy surface, and the magic tape assembly is a hook surface. A sliding bar is installed on one side of the support plate close to the power loss monitoring flowmeter. The sliding bar is slidably connected with the second chute. The front and rear side surfaces of the cleaning cloth are smooth surfaces.

[0026] With the above structural design, when it is necessary to clean the display screen, the support plate and the cleaning cloth in the placement box can be taken out, and then hold the sliding bar by hand, and wipe the dust on the display screen with the cleaning cloth. After wiping, place the support plate and the cleaning cloth inside the placement box. The smooth surfaces on the front and rear sides of the cleaning cloth facilitate placing the cleaning cloth in the placement box, preventing the cleaning cloth from warping due to friction with the scraping plate when placing the cleaning cloth. After the cleaning cloth is placed, the support block can be moved back and forth to drive the cleaning cloth and the support plate to move back and forth, so that the cleaning cloth rubs back and forth with the scraping plate, scraping the dust on the cleaning cloth, and the dust can be discharged through the placement box.

[0027] Preferably, the support block is slidably connected with the first chute. The center line of the column coincides with the center line of the threaded sleeve assembly. The threaded sleeve assembly is designed with a hollow structure, and the lower end surface of the threaded sleeve assembly is designed with an opening structure.

[0028] With the above structural design, when installing the support plate and the cleaning cloth, place the support plate and the cleaning cloth inside the placement box, make the center line of the column coincide with the center line of the threaded sleeve assembly, and then rotate the threaded sleeve assembly. The threaded sleeve assembly moves downward and sleeves on the column, thus completing the fixation of the support plate and the cleaning cloth.

[0029] Compared with the prior art, the beneficial effects of the present invention are: The portable distribution network power loss monitoring device:

[0030] An active bolt is provided. When storing the connecting strip, the movable strip and the baffle assembly are pushed to abut against the side fixing block, then the movable plate is rotated to the downward vertical state, and then the active bolt on the movable plate is rotated until the end of the active bolt abuts against the positioning groove on the connecting strip, thus completing the fixation of the connecting strip, facilitating the storage of the connecting strip and its portability;

[0031] A baffle assembly is provided. When measuring the power loss, the connecting strip is moved upward to the position of the indicating line, then the movable plate is rotated to the upward vertical state, and then the active bolt on the movable plate is rotated. When the active bolt moves towards the connecting strip, the limiting ring on the active bolt is driven to move towards the connecting strip, and the limiting ring drives the movable strip and the baffle assembly to move towards the connecting strip, so that the baffle assembly moves below the connecting strip to support the connecting strip. At the same time, the active bolt moves into the positioning groove on the connecting strip, thus completing the limitation of the connecting strip, making the extension of the connecting strip more stable, facilitating the increase of the distance between the fixed ball and the power loss monitoring flowmeter, facilitating the power loss monitoring of the distribution network, and preventing the influence of the line components in the distribution box due to too close distance and inconvenient operation;

[0032] A cleaning cloth is provided. When the display screen needs to be cleaned, the support plate and the cleaning cloth in the placement box can be taken out, and then the sliding bar is held, and the dust on the display screen is wiped with the cleaning cloth. After wiping, the support plate and the cleaning cloth are placed inside the placement box. The smooth surfaces on the front and back sides of the cleaning cloth facilitate placing the cleaning cloth in the placement box, preventing the cleaning cloth from warping due to friction with the scraper when placing the cleaning cloth. After the cleaning cloth is placed, the support block can be moved back and forth to drive the cleaning cloth and the support plate to move back and forth, so that the cleaning cloth and the scraper rub against each other, scraping off the dust on the cleaning cloth, and the dust can be discharged through the placement box.

[0045] Please refer to Figures 1 - 10, the present invention provides a technical solution: a portable power loss monitoring device for a distribution network, including a power loss monitoring flowmeter 1, a display screen 2, a connection component 3, a monitoring wire 4, a hollow column 5, a connection column 6, a fixing ball 7, a through groove 8, a heat dissipation hole 9, a fixing bolt 10, a butting block 11, a connecting plate 12, an insulating sleeve 13, a connecting strip 14, a positioning groove 15, a side fixing block 16, a plugging groove 17, a rotating shaft component 18, a movable plate 19, a movable bolt 20, a limiting ring 21, a rectangular groove 22, a circular groove 23, a guiding rod 24, a movable strip 25, a baffle component 26, a rectangular block 27, a placement box 28, a first sliding groove 29, a second sliding groove 30, a scraping plate 31, a cleaning cloth 32, a magic tape component 33, a support plate 34, a sliding strip 35, a support block 36, a column 37 and a threaded sleeve component 38. A display screen 2 is installed on the front surface of the power loss monitoring flowmeter 1, and connection components 3 are installed on both the left and right sides above the power loss monitoring flowmeter 1. Monitoring wires 4 are installed on the connection components 3, and a hollow column 5 and a connection column 6 are installed on the monitoring wires 4. The hollow column 5 is fixedly connected to the monitoring wire 4, and the hollow column 5 is fixedly connected to the connecting plate 12. The interiors of the hollow column 5 and the connection column 6 are designed with a conductive structure. After fixing the cable on the measured distribution network in the fixing ball 7, the current signal on the cable is transmitted to the power loss monitoring flowmeter 1 through the connection column 6, the hollow column 5 and the monitoring wire 4 to monitor the power loss of the cable. A fixing ball 7 is installed at the upper end of the connection column 6, and through grooves 8 are provided on the fixing ball 7. Heat dissipation holes 9 are provided on the fixing ball 7. A fixing bolt 10 is installed at the upper end of the fixing ball 7, and a butting block 11 is installed at the lower end of the fixing bolt 10. The diameter of the through groove 8 is larger than the diameter of the power grid cable. The cable on the measured distribution network is passed through the through groove 8 on the fixing ball 7, and then the fixing bolt 10 is rotated. The fixing bolt 10 drives the butting block 11 to move downward to fix the cable. A plurality of heat dissipation holes 9 are provided. The butting block 11 is designed in a circular structure. The butting block 11 is circular and located in the through groove 8. Anti-slip bumps are provided on the lower surface of the butting block 11. The heat dissipation holes 9 on the fixing ball 7 are beneficial to the heat dissipation of the cable inside the fixing ball 7, preventing the cable from getting too hot during long-term monitoring and causing a short circuit. The hollow column 5 is installed with a connecting plate 12. The connecting plate 12 is located directly above the power loss monitoring flowmeter 1, and an insulating sleeve 13 is installed on the connecting plate 12. The insulating sleeve 13 on the connecting plate 12 facilitates carrying the power loss monitoring flowmeter 1 by hand, making it more convenient to carry;

[0046] On both the left and right sides of the connecting plate 12, connecting bars 14 are installed. The connecting bars 14 are slidably connected to the insertion slots 17. The movable plate 19 is rotatably connected to the rotating shaft assembly 18. Indicator lines are provided on the connecting bars 14. When the connecting bars 14 are stressed, they can move up and down along the insertion slots 17. Therefore, when the connecting bars 14 are extended and retracted, they are more stable, and the connecting bars 14 will not shift. On the reverse sides below the connecting bars 14, positioning slots 15 are respectively opened. On both the left and right sides of the power loss monitoring flowmeter 1, side fixing blocks 16 are installed, and insertion slots 17 are respectively opened above the side fixing blocks 16. On the reverse sides of the side fixing blocks 16, movable plates 19 are hinged through the rotating shaft assembly 18. Movable bolts 20 are installed on the movable plates 19. When the connecting bars 14 move to the inner bottoms of the side fixing blocks 16, the center lines of the circular slots 23 on the side fixing blocks 16 coincide with the center lines of the positioning slots 15 on the connecting bars 14. When storing the connecting bars 14, push the movable bar 25 and the baffle assembly 26 until they are in contact with the side fixing blocks 16, then rotate the movable plates 19 to the downward vertical state, and then rotate the movable bolts 20 on the movable plates 19 until the ends of the movable bolts 20 are in contact with the positioning slots 15 on the connecting bars 14, thus completing the fixation of the connecting bars 14. A limit ring 21 is installed on the movable bolts 20. Rectangular slots 22 and circular slots 23 are opened on the reverse sides of the side fixing blocks 16. Guide rods 24 are respectively installed on the reverse sides of the side fixing blocks 16, and movable bars 25 are sleeved on the guide rods 24. The movable bars 25 are slidably connected to the guide rods 24. Limit blocks are provided at the outer ends of the guide rods 24. The baffle assembly 26 is slidably connected to the rectangular slots 22. When it is necessary to measure the power loss, move the connecting bars 14 upward to the position of the indicator lines, then rotate the movable plates 19 to the upward vertical state, and then rotate the movable bolts 20 on the movable plates 19. When the movable bolts 20 move towards the connecting bars 14, the limit rings 21 on the movable bolts 20 are driven to move towards the connecting bars 14. The limit rings 21 drive the movable bars 25 and the baffle assembly 26 to move towards the connecting bars 14, so that the baffle assembly 26 moves below the connecting bars 14 to support the connecting bars 14. At the same time, the movable bolts 20 move into the positioning slots 15 on the connecting bars 14, thus completing the limitation of the connecting bars 14, making the extension of the connecting bars 14 more stable, so as to facilitate increasing the distance between the fixed ball 7 and the power loss monitoring flowmeter 1, facilitating the power loss monitoring of the distribution network, preventing the influence of the line components in the distribution box due to too close distance, inconvenient operation, and a baffle assembly 26 is installed below the movable bar 25;

[0047] On the left side of the power loss monitoring flowmeter 1, a rectangular block 27 and a placement box 28 are installed. The upper surface of the placement box 28 is provided with a first chute 29. Near the side of the power loss monitoring flowmeter 1 inside the placement box 28, a second chute 30 is provided. On the side far from the power loss monitoring flowmeter 1 inside the placement box 28, a scraper 31 is installed. Inside the placement box 28, a cleaning cloth 32 is provided, and the cleaning cloth 32 is connected to a support plate 34 through a magic tape assembly 33. There are two scrapers 31. A plurality of through holes are provided on the scraper 31, and the scraper 31 is located at the middle position inside the placement box 28. The scraper 31 is in contact with the surface of the cleaning cloth 32. The magic tape assembly 33 is fixed on the support plate 34. The surface of the cleaning cloth 32 in contact with the magic tape assembly 33 is a plush surface, and the magic tape assembly 33 is a hook surface. On the side of the support plate 34 close to the power loss monitoring flowmeter 1, a slide bar 35 is installed. The slide bar 35 is slidably connected to the second chute 30. The front and rear sides of the cleaning cloth 32 are provided with smooth surfaces. When it is necessary to clean the display screen 2, the support plate 34 and the cleaning cloth 32 in the placement box 28 can be taken out, and then the slide bar 35 is held by hand, and the dust on the display screen 2 is wiped with the cleaning cloth 32. After the wiping is completed, the support plate 34 and the cleaning cloth 32 are placed inside the placement box 28. The smooth surfaces on the front and rear sides of the cleaning cloth 32 facilitate placing the cleaning cloth 32 inside the placement box 28, preventing the cleaning cloth 32 from warping due to friction with the scraper 31 when the cleaning cloth 32 is placed. After the cleaning cloth 32 is placed, the support block 36 can be moved back and forth to drive the cleaning cloth 32 and the support plate 34 to move back and forth, so that the cleaning cloth 32 and the scraper 31 rub against each other, and the dust on the cleaning cloth 32 is scraped off. The dust can be discharged through the placement box 28. Above the support plate 34, a support block 36 is installed, and above the support block 36, a column 37 is installed. On the rectangular block 27, a threaded sleeve assembly 38 is installed. The support block 36 is slidably connected to the first chute 29. The center line of the column 37 coincides with the center line of the threaded sleeve assembly 38. The threaded sleeve assembly 38 is designed with a hollow structure, and the lower end surface of the threaded sleeve assembly 38 is designed with an open structure. When installing the support plate 34 and the cleaning cloth 32, the support plate 34 and the cleaning cloth 32 are placed inside the placement box 28, so that the center line of the column 37 coincides with the center line of the threaded sleeve assembly 38. Then the threaded sleeve assembly 38 is rotated, and the threaded sleeve assembly 38 moves downward and sleeves on the column 37, thereby completing the fixation of the support plate 34 and the cleaning cloth 32.

[0048] Working principle: When using this portable power loss monitoring device for a distribution network, first, when measuring power loss, move the connecting bar 14 upward to the position of the indicating line, then rotate the movable plate 19 to the vertically upward state, and then rotate the movable bolt 20 on the movable plate 19. When the movable bolt 20 moves towards the connecting bar 14, it drives the limiting ring 21 on the movable bolt 20 to move towards the connecting bar 14. The limiting ring 21 drives the movable bar 25 and the baffle assembly 26 to move towards the connecting bar 14, so that the baffle assembly 26 moves below the connecting bar 14 to support the connecting bar 14. At the same time, the movable bolt 20 moves into the positioning groove 15 on the connecting bar 14, thereby completing the limiting of the connecting bar 14 and making the extension of the connecting bar 14 more stable, which is convenient for increasing the distance between the fixed ball 7 and the power loss monitoring flowmeter 1 and facilitating the power loss monitoring of the distribution network. Pass the cable on the measured distribution network through the through groove 8 on the fixed ball 7, and then rotate the fixed bolt 10. The fixed bolt 10 drives the abutting block 11 to move downward to fix the cable, and the power loss is monitored through the power loss monitoring flowmeter 1.

[0049] When storing the connecting bar 14, push the movable bar 25 and the baffle assembly 26 until they abut against the side fixing block 16, then rotate the movable plate 19 to the vertically downward state, and then rotate the movable bolt 20 on the movable plate 19. Rotate the movable bolt 20 until its end abuts against the positioning groove 15 on the connecting bar 14, thus completing the fixing of the connecting bar 14, facilitating the storage of the connecting bar 14 and its carrying.

[0050] When the display screen 2 needs to be cleaned, the support plate 34 and the cleaning cloth 32 in the placement box 28 can be taken out. Then hold the sliding bar 35 and wipe the dust on the display screen 2 with the cleaning cloth 32. After wiping, place the support plate 34 and the cleaning cloth 32 inside the placement box 28. The smooth surfaces on the front and back sides of the cleaning cloth 32 facilitate placing the cleaning cloth 32 in the placement box 28, preventing the cleaning cloth 32 from warping due to friction with the scraping plate 31 when placing the cleaning cloth 32. After the cleaning cloth 32 is placed, the support block 36 can be moved back and forth to drive the cleaning cloth 32 and the support plate 34 to move back and forth, so that the cleaning cloth 32 rubs back and forth with the scraping plate 31 to scrape off the dust on the cleaning cloth 32, and the dust can be discharged through the placement box 28. Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
