Description

Technical Field

[0001] The present invention relates to the technical field of power loss monitoring, in particular to a power distribution network power loss monitoring feedback device. Background Art

[0002] The distribution network refers to a power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, distribution network power cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. During the use of the distribution network, the power loss is usually monitored by a monitoring device. For example, the patent with the authorization announcement number CN117937274B discloses a distribution network power loss monitoring device to monitor the loss of power cables.

[0003] However, the inventor found that the patent still has the following problems:

[0004] 1. As Figure 5 As shown, although the guide cover and dust absorption sheet can be used for protection to ensure monitoring stability and prevent the device from being affected by dust, dust will adhere to the surface of the cable, and the dust absorption sheet is a certain distance away from the cable, so it is difficult to absorb the dust around the cable. Dust adhering to the cable will affect the accuracy of the device test;

[0005] 2. Relying solely on connecting posts and wires to test whether the cable is leaking electricity is very likely to result in test errors, which in turn leads to inaccurate device testing;

[0006] 3. Such as Figure 1 and 5 As shown, the description in paragraph 46 of the specification states, "When the vacuum pump 606 is in operation, the airflow at the heat sink 601 passes through the filter 604 and enters the connecting frame 602, and then enters the first connecting pipe 605 from the connecting frame 602. The airflow in the first connecting pipe 605 is discharged through the air outlet of the vacuum pump 606, and then enters the exhaust pipe 608 from the second connecting pipe 607, and then is discharged from the exhaust pipe 608. The wind discharged from the exhaust pipe 608 can dissipate heat for the warning light row 505 and the prompt board 504, so that the performance is better, and at the same time, the air flow rate at the heat sink 601 is accelerated, so that the heat dissipation effect of the heat sink 601 is better, and the monitoring effect of the device is better." It can be concluded from this paragraph that the airflow at the heat sink is hot air, and the hot air is pumped to the warning light row and the prompt board by the vacuum pump. Obviously, heat will continue to be discharged to the warning light row and the prompt board, which has a certain warming effect on the warning light row and the prompt board. For example, in winter, when the air conditioner blows hot air, the heat dissipation effect is likely to be worse. Summary of the invention

[0007] In view of the above-mentioned technical problems existing in the prior art, a distribution network power loss monitoring feedback device is provided, which solves the problem that it is difficult to absorb the dust around the cable. The dust adhering to the cable will affect the accuracy of the device test; relying solely on connecting columns and wires to test whether the cable is leaking electricity is very likely to result in test errors, which in turn leads to inaccurate device testing and continuous heat discharge to the warning light row and prompt board in CN117937274B, which cannot achieve good heat dissipation.

DETAILED DESCRIPTION

[0038] See also Figure 1-10 , further illustrate the embodiments of the present invention;

[0039] A power distribution network power loss monitoring feedback device, comprising a monitoring box 1, an inspection component 4 and a dust collection component 5:

[0040] like Figure 1 As shown in or 2, the monitoring box 1 is installed with a smart meter 11, a controller 12, a wireless signal transmission module 13 and a terminal 14. There are two terminals 14, and both terminals 14 are installed with wires, which are connected to the cable. The terminal 14 is electrically connected to the smart meter 11, and the lower end of the monitoring box 1 is a heat dissipation end. The monitoring box 1 dissipates its internal heat through the heat dissipation end. A heat dissipation mesh plate 15 is installed at the heat dissipation end of the monitoring box 1. The heat dissipation mesh plate 15 can prevent dust from entering the monitoring box 1. During monitoring, the smart meter 11 is used to detect the power cable power of the distribution network in real time, and compare it with the preset loss threshold inside the controller 12. The controller 9 is connected to a data comparison library. The power loss value detected by the smart meter 11 is compared with the preset loss threshold, and the comparison situation can be wirelessly output to the background service computer device through the wireless signal wireless signal transmission module 13;

[0041] like Figure 2 , 3, 5 and 6, the inspection component 4 is provided with at least one, which is used to detect whether the cable is damaged and causes power loss. The device needs to be equipped with a drone to drive the inspection component 4 to move along the cable direction during the inspection. The inspection component 4 includes an inspection box 41, a cleaning box 42, a camera 43 and a driving member 44. Through holes 411 are opened on opposite sides of the inspection box 41, and the wires on the terminal 14 are fixedly connected to the inspection box 41, so that when the inspection component 4 moves, the wires on the terminal 14 also move with it; the cleaning box 42 is installed in one of the through holes 411, and mounting holes 421 are opened on both sides of the cleaning box 42. The other through hole 411 and the two mounting holes 421 are used to insert the cable, and the inner wall of the cleaning box 42 is fixed with a circle for cleaning The brush 422 for cleaning the cable. It should be noted that when the inspection component 4 moves, the cleaning box 42 is in front and the wire on the terminal 14 is in the back. After the brush 422 cleans the cable, it is beneficial for the wire on the terminal 14 to accurately test whether the cable has leakage, which can improve the accuracy of the device in detecting whether the cable has power loss. A circle of dust suction sponge 423 is fixed in the inner installation hole 421, the drive member 44 is arranged in the inspection box 41, and the camera 43 is installed on the drive member 44. The camera 43 is used to shoot around the cable. Before the inspection, the camera 43 is used to shoot around the qualified cable as a reference standard for the later inspection. The standard picture will be transmitted to the background service computer equipment through the wireless signal transmission module 13. During the inspection, the cable is passed through the dust suction sponge 423, and the dust suction sponge 423 is in contact with the outer wall of the cable, which plays a dust-proof role for the installation hole 421 where the dust suction sponge 423 is located, and prevents dust from entering the inspection box 41 through the installation hole 421 at the dust suction sponge 423, thereby preventing the camera 43 in the inspection box 41 from sticking to dust. During the inspection process, the driving member 44 will drive the camera 43 to rotate slowly around the cable to take pictures of the surrounding areas of the cable. If the background service computer equipment detects that the picture taken during the inspection is the same as the standard picture, it means that the cable is not damaged; on the contrary, if the background service computer equipment detects that the cable is damaged and there is power loss in the cable, the background service computer equipment will issue a prompt. The camera 43 takes pictures of the surrounding areas of the cable and the terminal 14 and the wire measure the current through the dual detection, which can effectively avoid the problem of inaccurate equipment testing due to test errors; two inspection components 4 can also be set, which can not only improve the balance of the equipment, but also help the equipment to detect cable power loss more accurately.

[0042] like Figure 1 , 2As shown in Figures 4, 5, 6 and 7, a through opening 412 is provided on the inspection box 41; the driving member 44 includes a gear 1 441, a gear 2 442, a motor 1 443, a synchronous belt 444 and a rotating rod 445, the gear 1 441 is rotatably connected to the inspection box 41, the camera 43 is installed on the inner side of the gear 1 441, the gear 2 442 is rotatably connected to the outer wall of the inspection box 41, and the inner end of the gear 2 442 passes through the through opening 412 and is meshed with the gear 1 441, the rotating rod 445 is fixed at the center of the side of the gear 2 442, the synchronous belt 444 is installed on the motor 1 443 and the rotating rod 445, the motor 1 443 is a reduction motor, after the motor 1 443 is powered on, the motor 1 443 drives the rotating rod 445 to rotate through the synchronous belt 444, and the rotating rod 445 drives the gear 2 442 to rotate to transmit the gear 1 441, so that the camera 43 can rotate around along the outside of the cable.

[0043] like Figure 1 and 2 The device also includes an alarm component 7, which includes a mounting plate 71, a second motor 72, a rotating shaft 73, an alarm light row 74 and a prompt plate 75. The mounting plate 71 is fixed to one side of the monitoring box 1, the second motor 72 is fixed on the mounting plate 71, the rotating shaft 73 is fixed at the output end of the second motor 72, the alarm light row 74 and the prompt plate 75 are both fixed on the rotating shaft 73, the second motor 72, the alarm light row 74 and the prompt plate 75 are all electrically connected to the controller 12. When in use, the controller 12 will start the second motor 72, the alarm light row 74 and the prompt plate 75, and the second motor 72 will drive the rotating shaft 73 to rotate, thereby realizing the rotation of the alarm light row 74 and the prompt plate 75, and the rotation of the light source is used to warn pedestrians to avoid accidental touch by others, thereby ensuring the safety of monitoring.

[0044] like Figure 1 , 2 As shown in Figure 9, the dust collecting assembly 5 includes a dust collecting box 51, a vacuum pump assembly 52 and a dust suction pipe 53. The dust collecting box 51 is detachably connected to the monitoring box 1. The vacuum pump assembly 52 is installed on the top of the dust collecting box 51 and communicates with the interior thereof. The number of dust suction pipes 53 is equal to the number of cleaning boxes 42, and one end of the dust suction pipe 53 is sealed and plugged on the outer wall of the dust collecting box 51 and communicates with the interior thereof, and the other end is sealed and plugged at the bottom of the cleaning box 42 and communicates with the interior thereof. The vacuum pump assembly 52 is electrically connected to the controller 12, and the working interval time of the vacuum pump assembly 52 can be preset by the controller 12. When the vacuum pump assembly 52 is working, the air in the dust collecting box 51 is sucked out to make the interior thereof in a negative pressure state. Therefore, the dust in the cleaning box 42 can be sucked into the dust collecting box 51 through the dust suction pipe 53, and the dust in the cleaning box 42 can be discharged in time to avoid clogging of the cleaning box 42.

[0045] like Figure 1 , 2As shown in FIGS. 8 and 9, the vacuum pump assembly 52 includes a vacuum pump 521, an air inlet pipe 522, an air outlet pipe 523 and an air outlet pipe frame 525. The vacuum pump 521 is fixed to the top of the dust box 51, the air inlet pipe 522 is sealed and installed at the air inlet end of the vacuum pump 521, and the lower end of the air inlet pipe 522 passes through the top of the dust box 51 and communicates with the interior thereof, the air outlet pipe 523 is sealed and installed at the air outlet end of the vacuum pump 521, and the lower end of the air outlet pipe 523 extends to the heat dissipation end of the monitoring box 1. In order to expand the air supply surface, a heat dissipation mesh plate is fixed at the bottom of the monitoring box 1 15, the air supply frame 524 is connected to the lower end of the air outlet pipe 523, the air outlet pipe frame 525 is installed on the air outlet pipe 523, the air outlet of the air outlet pipe frame 525 faces the alarm light row 74 and the prompt board 75, the vacuum pump 521 in the vacuum pump assembly 52 is electrically connected to the controller 12, the controller 12 is used to control the start and stop and working time of the vacuum pump 521, when the vacuum pump 521 is working, the air in the dust box 51 is sucked out through the air inlet pipe 522, so that the inside becomes a negative pressure state, and the dust collection box 4 is cleaned by the dust collection pipe 53. 2 is sucked into the dust collecting box 51, and the air outlet pipe 523 will convey the air sucked out by the vacuum pump 521 to the air supply frame 524 and the air outlet pipe rack 525. The air delivered by the air supply frame 524 and the air outlet pipe rack 525 is cold air. The airflow discharged by the air supply frame 524 can blow away the heat at the heat dissipation end of the monitoring box 1, thereby improving the heat dissipation efficiency of the heat dissipation end of the monitoring box 1. The airflow discharged by the air outlet pipe rack 525 can blow away the heat generated by the alarm light row 74 and the prompt board 75. The setting of the vacuum pump assembly 52 can not only complete the dust extraction operation, It can also deliver cold air to the heat dissipation end of the monitoring box 1, the alarm light row 74 and the prompt plate 75. The vacuum pump assembly 52 realizes multiple uses and improves the heat dissipation efficiency of the heat dissipation end of the monitoring box 1, the alarm light row 74 and the prompt plate 75. Compared with CN117937274B which separately sets up a vacuum pump 521 to extract heat from the heat dissipation end of the monitoring box 1, it is more economical and practical. At the same time, it also effectively solves the problem of poor heat dissipation effect of the alarm light row 74 and the prompt plate 75 caused by sucking hot air at the heat dissipation end of the monitoring box 1 and discharging it to the alarm light row 74 and the prompt plate 75.

[0046] like Figure 1 , 2As shown in 8, in order to adjust the wind force and control the direction of the airflow in the air outlet pipe 523, solenoid valves 526 are installed on the air outlet pipe 523 and the air outlet pipe rack 525. The solenoid valve 526 on the air outlet pipe 523 is located below the air outlet pipe rack 525, and the two solenoid valves 526 are electrically connected to the controller 12. When the vacuum pump 521 is working, the two solenoid valves 526 are set to work intermittently through the controller 12. For example, the solenoid valve 526 on the air outlet pipe 523 is closed after working for 5 seconds, and then the solenoid valve 526 on the air outlet pipe rack 525 is started, and the work is suspended after working for 5 seconds. Then the solenoid valve 526 on the air outlet pipe 523 works, and this cycle is repeated. In this way, the wind force delivered to the heat dissipation end of the monitoring box 1, the alarm light row 74 and the prompt board 75 is relatively large, which is conducive to the rapid blowing away of heat.

[0047] like Fig. 9 and 10 In order to prevent the vacuum pump 521 and the air inlet pipe 522 from being blocked, a filter assembly 6 is further provided in the dust box 51. The filter assembly 6 includes a filter screen 61, a spring 62 and a second dust suction sponge 63. The filter screen 61 is provided with two filters distributed inside and outside and detachably connected to the top of the dust box 51, and the two filter screens 61 surround the air inlet pipe 522. The spring 62 is provided with a plurality of springs 62 and all are fixed between the two filter screens 61. The second dust suction sponge 63 is fixed on the inner wall of the inner filter screen 61. When the vacuum pump 521 is evacuating air, the air in the dust box 51 will pass through the two filter screens 61 and the second dust suction sponge 63 in turn and enter the air inlet pipe 522. In this process, the two filter screens 61 and the second dust suction sponge 63 will filter the air in turn to prevent dust in the air from being drawn into the air inlet pipe 522 and the vacuum pump 521. The suction force generated when exhausting air will cause the filter 61 to deform to a certain extent. At the same time, the filter 61 will also be affected by the shock force, and the spring 62 will elastically deform along with the filter 61. Since the spring 62 is elastic, it can not only absorb the shock force exerted on the filter 61, but also restore the deformed part of the filter 61, thereby protecting the filter 61 and extending the service life of the filter assembly 6.

[0048] like Figure 1 and 2 As shown, the device also includes a hanging rope assembly 2, which includes a mounting ring 21, a hanging rope 22 and an insulating sleeve 23. The mounting ring 21 is fixed to the top of the monitoring box 1, the insulating sleeve 23 is sleeved on the cable, and the hanging rope 22 is fixed between the mounting ring 21 and the insulating sleeve 23. The insulating sleeve 23 is sleeved on the cable 12, and then the mounting ring 21 is installed on the top of the monitoring box 1, the hanging rope 22 is passed through the mounting ring 21, and then the two ends of the hanging rope 22 are installed between the insulating sleeve 23 through bolts, so that the monitoring box 1 is installed together with the hanging rope assembly 2. When the hanging rope assembly 2 is used, it is convenient to fix the monitoring box 1 to ensure the stability of the equipment installation.

[0049] like Figure 1 and 2 As shown, in order to provide shade and rain protection for the monitoring box 1 and the inspection component 4, the device also includes a protective component 3, the protective component 3 includes a support frame 31 and a parasol 32, the parasol 32 is located above the inspection component 4 and fixed on the support frame 31, and the motor 443 is fixed on the support frame 31.

[0050] Before using the device, it needs to be installed on the cable. If only one inspection component 4 is provided, the inspection component 4 and the hanging rope component 2 can be installed on the cable in any order. If two inspection components 4 are provided for the overall stability of the device and more accurate detection, they are installed on the cable in the order of inspection component 4-hanging rope component 2-inspection component 4. Specifically, the cable is passed through the through hole 411 on one of the inspection boxes 41, and then straightly passed through the two installation holes 421 on the cleaning box 42, such as Figure 6 As shown, a sealing door panel is installed through an opening on one side of the inspection box 41. When threading the cable, the sealing door panel can be opened to facilitate threading; then the insulating sleeve 23 is sleeved on the cable 12, and then the mounting ring 21 is installed on the top of the monitoring box 1, the hanging rope 22 is passed through the mounting ring 21, and then the two ends of the hanging rope 22 are installed between the bolts and the insulating sleeve 23, so that the monitoring box 1 and the hanging rope assembly 2 are installed together. With the use of the hanging rope assembly 2, it is convenient to fix the monitoring box 1 to ensure the stability of the equipment installation, and then the wire on the terminal 14 is fixed to the inspection box 41, and the wire is connected to the cable together. The wire is preferably located inside the inspection box 41, and the inspection box 41 can protect the wire; then another inspection box 41 can be installed on the cable according to the above method to complete the installation of the equipment.

[0051] Before testing, the camera 43 is used to take pictures around the qualified cable as a reference standard for later testing. The standard picture will be transmitted to the background service computer device through the wireless signal transmission module 13;

[0052] When inspecting the cable, one end of the rope is fixed to the support frame 31 of the protection component 3, and the other end is fixed to the drone. The drone is used to drive the device to inspect along the cable. When moving, the bristles 422 in the cleaning box 42 will first brush the outer wall of the cable, which is conducive to the accurate testing of the wire on the terminal 14 to see if there is leakage in the cable, and can improve the accuracy of the device in detecting whether there is power loss in the cable. When brushing, it is located in the closed cleaning box 42 to prevent dust from spreading everywhere. In order to further enhance the dustproof effect of the cleaning box 42, a circle of dust absorption sponge 423 is installed at the opening 412 on the inner side of the cleaning box 42, which can effectively prevent dust from entering the inspection box 41, ensuring that the camera 43 is in a clean environment;

[0053] During the detection, the smart meter 11 is used to detect the power situation of the power cable of the distribution network in real time, and compare it with the preset loss threshold value inside the controller 12, wherein the controller 9 is connected to a data comparison library, and the power loss value detected by the smart meter 11 is compared with the preset loss threshold value, and the comparison situation can be wirelessly output to the background service computer device through the wireless signal wireless signal transmission module 13; in addition, the motor 1 443 will be started, and the motor 1 443 will drive the rotating rod 445 to rotate through the synchronous belt 444, and the rotating rod 445 will drive the gear 2 442 to rotate to transmit the gear 1 441, so that the camera 43 will circle around the outside of the cable and rotate slowly, so that the outer wall of the cable can be photographed. If the background service computer device detects that the picture taken by the test is the same as the standard picture, it means that the cable is not damaged; on the contrary, if the background service computer device detects that the cable is damaged and the cable has power loss, the background service computer device will issue a prompt and feedback the information to the staff so that the staff can understand where the power loss of the cable occurs in time. The double detection of photographing the surroundings of the cable by the camera 43 and measuring the current of the terminal 14 and the wire can effectively avoid the problem of inaccurate equipment testing due to test errors.

[0054] During the monitoring process, the controller 12 will intermittently start the vacuum pump 521, and draw out the air in the dust box 51 through the air inlet pipe 522, so that the interior of the dust box 51 becomes a negative pressure state, and the dust in the cleaning box 42 is promptly drawn into the dust box 51 through the dust suction pipe 53 to prevent the cleaning box 42 from being filled with dust. At the same time, the air outlet pipe 523 will transport the air drawn out by the vacuum pump 521 to the air supply frame 524 and the air outlet pipe rack 525. The air delivered by the air supply frame 524 and the air outlet pipe rack 525 is cold air. The airflow discharged through the air supply frame 524 can blow away the heat at the heat dissipation end of the monitoring box 1, thereby improving the heat dissipation efficiency of the heat dissipation end of the monitoring box 1. The airflow discharged from the air outlet pipe rack 525 can The heat generated by the alarm light row 74 and the prompt plate 75 is blown away. The setting of the vacuum pump assembly 52 can not only complete the dust extraction operation, but also deliver cold air to the heat dissipation end of the monitoring box 1, the alarm light row 74 and the prompt plate 75. The vacuum pump assembly 52 realizes multiple uses and improves the heat dissipation efficiency of the heat dissipation end of the monitoring box 1, the alarm light row 74 and the prompt plate 75. Compared with CN117937274B, which separately sets the vacuum pump 521 to extract the heat from the heat dissipation end of the monitoring box 1, it is more economical and practical. At the same time, it also effectively solves the problem of poor heat dissipation effect of the alarm light row 74 and the prompt plate 75 due to the hot air at the heat dissipation end of the monitoring box 1 being sucked and discharged to the alarm light row 74 and the prompt plate 75;

[0055] In addition, when the equipment is running, the alarm component 7 will also be started. Specifically, the controller 12 will start the motor 2 72, the warning light array 74 and the prompt plate 75. The motor 2 72 drives the rotating shaft 73 to rotate, thereby realizing the rotation of the warning light array 74 and the prompt plate 75. The light source rotates to warn pedestrians to avoid accidental touch by others, thereby ensuring the safety of monitoring.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
