Description

Technical Field

[0001] The present invention relates to the technical field of power grid equipment monitoring, and in particular to a power grid equipment line spatial position sensing device and a working method thereof. Background Art

[0002] As the scale of power grids continues to expand, the safe operation of power grid equipment and lines has become crucial. Power grid equipment includes transformers, circuit breakers, disconnectors, etc., and lines include overhead lines and cable lines. During the operation of these equipment and lines, the changes in their spatial positions may affect the normal operation of the power grid. Therefore, real-time monitoring of the spatial positions of power grid equipment and lines can timely detect potential fault hazards and improve the reliability and safety of the power grid.

[0003] Existing power grid equipment line monitoring equipment usually uses optical sensors for monitoring when in use. However, when installing sensors using such power grid equipment line monitoring equipment, the operating steps are relatively complicated, the installation time required is long, the installation and disassembly efficiency is low, and the complicated operating steps are prone to operational deviations. The installation stability and reliability of the sensors cannot be guaranteed, which in turn affects the subsequent operation of the power grid equipment line monitoring equipment. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art in which, when installing sensors of power grid equipment monitoring equipment, the operating steps are relatively complicated, the installation time is long, the installation and disassembly efficiency is low, and operation deviations are prone to occur, and the installation stability and reliability of the sensor cannot be guaranteed. A power grid equipment line space position sensing device and a working method thereof are provided. Through the cooperation of the mounting block and the mounting groove, the limit bar is slidably installed in the inside of the limit groove, which is conducive to providing a limit and preventing the mounting block from falling off. The installation of the mounting block and the limit member is further realized by a spring, which reduces the difficulty of installation, avoids operation deviations, and can improve the installation efficiency while ensuring the stability and reliability of the installation of the sensor component.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A spatial position sensing device for a power grid equipment line comprises a sensing component, a mounting component is arranged on the side of the sensing component, a protective cleaning component is arranged on the outside of the sensing component, the sensing component comprises a position sensor, the mounting component comprises a mounting block and a mounting plate, the mounting block is mounted on the side of the position sensor, limiting strips are installed on both sides of the mounting block, a mounting groove is fixedly installed on the side of the mounting plate, limiting grooves are symmetrically provided on the inner side of the mounting groove, the limiting strips are slidably installed inside the limiting groove, the mounting block is slidably installed inside the mounting groove, a fixing frame is symmetrically installed on one side of the mounting groove, a spring is movably installed on the inner side of the fixing frame, a limiting member is fixedly installed on one end of the spring, one end of the limiting member is movably connected to the inner side of the mounting groove, and a handle is installed between the two limiting members.

[0007] By sliding the mounting block inside the mounting groove, the limit strip is slid inside the limit groove, which is conducive to providing a limit and preventing the mounting block from falling off. By holding the handle and pulling it outward, the limit piece is driven to move outward, so that the spring is compressed. When the mounting block is slid inside the mounting groove, the handle is released to extend the spring, thereby driving one end of the limit piece to be installed inside the mounting block, which is conducive to limiting the mounting block and ensuring the stability and reliability of the installation of the sensor component. The operation is convenient, which facilitates the installation and disassembly of the optical sensor, reduces the difficulty of installation, and thus improves the installation efficiency. At the same time, it is convenient to maintain and overhaul the optical sensor, improves the maintenance efficiency, and thus prolongs the service life of the optical sensor. And the simple installation operation can also avoid operational deviations, so as to further improve the stability and reliability of the installation of the sensor component.

[0008] Furthermore, the position sensor is an optical sensor, and an optical lens is installed on the side of the optical sensor.

[0009] Optical sensors can detect the existence, position, speed and other parameters of objects through optical principles such as light intensity, light frequency or phase. They have the advantages of non-contact, high precision and fast response speed, and are suitable for position monitoring of power grid equipment lines.

[0010] Furthermore, the protective cleaning component includes a light-transmitting protective cover, which is sleeved on the outside of the optical lens. A movable groove is installed on the top of the light-transmitting protective cover, and a pneumatic telescopic rod is movably installed inside the movable groove. A movable block is fixedly connected to one end of the pneumatic telescopic rod, and a cleaning brush holder is installed on the side of the movable block.

[0011] As an important component of optical sensors, optical lenses can control the transmission, distribution, focusing and other performance of optical fibers, which directly affects the accuracy of subsequent monitoring results. Therefore, a light-transmitting protective cover is set to protect the optical lens from damage while avoiding affecting the monitoring function of the optical lens.

[0012] Furthermore, a plurality of cleaning brushes are distributed inside the cleaning brush holder, and the cleaning brushes are connected to the surface of the light-transmitting protective cover.

[0013] A cleaning brush holder is provided to clean dust and impurities on the surface of the light-transmitting protective cover, so as to improve the clarity and light transmittance of the light-transmitting protective cover and ensure the acquisition accuracy of the optical sensor.

[0014] Furthermore, first docking blocks are installed at both ends of the light-transmitting protective cover, and clamping blocks are installed on the sides of the first docking blocks.

[0015] Furthermore, second docking blocks are installed at both ends of the optical lens, a card slot is opened on the side of the second docking block, and the card slot is installed inside the card slot.

[0016] Furthermore, the outer sides of the first docking block and the second docking block are provided with limiting sleeves.

[0017] Furthermore, it also includes a positioning component, which is arranged on the power grid equipment line to locate the position of the power grid equipment line.

[0018] The working method of the spatial position sensing device of the power grid equipment line includes:

[0019] Arrive at the power grid equipment line, select a positioning point, and set the positioning component on the positioning point;

[0020] Fix the sensor component by installing the component, and establish a matching relationship between the sensor component and the positioning component;

[0021] The sensing component monitors the position fluctuation of the power grid equipment line in real time according to the corresponding positioning component;

[0022] When position fluctuations of power grid equipment lines are detected, an alarm is issued based on the corresponding positioning points.

[0023] In order to adapt to different scenarios of power grid equipment line position monitoring, when installing the power grid equipment line spatial position sensor device, first select the positioning point, then set the corresponding positioning component, and reflect the position fluctuation of the power grid equipment line through the position change of the positioning component. This method of setting the positioning component to cooperate with the sensor component to monitor the position fluctuation of the power grid equipment line can reduce the restrictions on the installation position of the power grid equipment line spatial sensor device, further reduce the difficulty of installation operation, and avoid the lack of accuracy of power grid equipment line position monitoring caused by installation deviation. And when the position fluctuation is detected, the accurate position of the fluctuation can also be quickly located through the positioning point, thereby improving maintenance efficiency.

[0024] Furthermore, the sensing component monitors the position fluctuation of the power grid equipment line in real time according to the corresponding positioning component, including:

[0025] The sensing component collects the position information of the corresponding positioning component in real time;

[0026] Compare the position information at the preset time points and calculate the fluctuation parameters;

[0027] When the fluctuation parameter exceeds a preset threshold, it is determined that there is position fluctuation.

[0028] The beneficial effects of the present invention are:

[0029] (1) By sliding the mounting block inside the mounting groove, the limit bar is slid inside the limit groove, which is conducive to providing limit and preventing the mounting block from falling off. By holding the handle and pulling it outward, the limit piece is driven to move outward, so that the spring is compressed. When the mounting block is slid inside the mounting groove, the handle is released to extend the spring, thereby driving one end of the limit piece to be installed inside the mounting block, which is conducive to limiting the mounting block and ensuring the stability and reliability of the optical sensor installation. The convenient operation facilitates the installation and disassembly of the optical sensor, reduces the installation difficulty, and thus improves the installation efficiency. At the same time, it is convenient to maintain and repair the optical sensor, improves the maintenance efficiency, and thus prolongs the service life of the optical sensor. The simple installation operation can also avoid operation deviation, so as to further improve the stability and reliability of the sensor component installation.

[0030] (2) The pneumatic telescopic rod is extended and retracted, thereby pushing the moving block to drive the cleaning brush holder to move inside the moving groove, so that the cleaning brush holder can effectively clean the dust and impurities on the surface of the light-transmitting protective cover, ensuring the cleanliness of the light-transmitting protective cover, which is beneficial to improving the clarity and light transmittance of the light-transmitting protective cover and improving the accuracy of optical lens monitoring.

[0031] (3) By setting up a positioning component to cooperate with the sensor component to monitor the position fluctuation of the power grid equipment line, the restrictions on the installation position of the power grid equipment line space sensor device are reduced, the difficulty of installation operation is further reduced, and the problem of insufficient accuracy of the power grid equipment line position monitoring caused by installation deviation is avoided. After the position fluctuation is detected, the exact position of the fluctuation can be quickly located through the positioning point, thereby improving the maintenance efficiency.

DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 6As shown, the power grid equipment line spatial position sensing device shown in this embodiment includes a sensing component 1, a mounting component 2 is arranged on the side of the sensing component 1, a protective cleaning component 3 is arranged on the outside of the sensing component 1, the sensing component 1 includes a position sensor, the mounting component 2 includes a mounting block 201 and a mounting plate 206, the mounting block 201 is installed on the side of the position sensor, limit strips 202 are installed on both sides of the mounting block 201, and the side of the mounting plate 206 is fixedly installed with a mounting groove 203, A limiting groove 204 is symmetrically provided on the inner side of the installation groove 203, the limiting strip 202 is slidably installed inside the limiting groove 204, the installation block 201 is slidably installed inside the installation groove 203, a fixing frame 205 is symmetrically installed on one side of the installation groove 203, a spring 207 is movably installed on the inner side of the fixing frame 205, a limiting member 208 is fixedly installed on one end of the spring 207, one end of the limiting member 208 is movably connected to the inner side of the installation groove 203, and a handle 209 is installed between the two limiting members 208.

[0043] In order to optimize the installation operation of the line spatial position sensor device of the power grid equipment, the installation block 201 is slidably installed inside the installation groove 203, so that the limit strip 202 can be slidably installed inside the limit groove 204, which is conducive to providing limit and preventing the installation block 201 from falling off. When installing the sensor component 1, by pulling the handle 209 outward, the limit member 208 is driven to move outward, so that the spring 207 is compressed. After placing the sensor component 1, release the handle 209, so that the spring 207 extends, and then drives a section of the limit member 208 to be installed inside the installation block 201, so as to limit the installation block 201 and ensure the stability and reliability of the installation of the sensor component 1. If the sensor component 1 needs to be disassembled later, it can also be quickly disassembled by pulling the handle 209.

[0044] The position sensor is an optical sensor 101 , and an optical lens 102 is installed on the side of the optical sensor 101 .

[0045] The optical sensor 101 can detect the existence, position, speed and other parameters of an object through optical principles such as light intensity, light frequency or phase, and has the advantages of non-contact, high precision and fast response speed, and can accurately obtain the location of power grid equipment lines.

[0046] The optical sensor 101 is internally installed with modules such as a light source module, a signal processing module, a control and communication module, etc., which can realize the position monitoring of power grid equipment lines.

[0047] As one of the important components of the light source module, the optical lens 102 can generate detection light for monitoring the position of the power grid equipment line, so as to cooperate with the positioning component to realize the recognition of the position fluctuation of the power grid equipment line. However, since the power grid equipment lines are mostly set in outdoor open areas, dust is easily accumulated on the optical lens 102, affecting the subsequent position fluctuation recognition.

[0048] Therefore, the protective cleaning component 3 is provided to ensure the cleanliness of the optical lens 102 to ensure the accuracy of subsequent position fluctuation recognition.

[0049] The protective cleaning component 3 includes a light-transmitting protective cover 301, which is sleeved on the outside of the optical lens 102. A movable groove 303 is installed on the top of the light-transmitting protective cover 301, and a pneumatic telescopic rod 305 is movably installed inside the movable groove 303. One end of the pneumatic telescopic rod 305 is fixedly connected to a movable block 304, and a cleaning brush holder 302 is installed on the side of the movable block 304.

[0050] A plurality of cleaning brushes are distributed inside the cleaning brush holder 302 , and the cleaning brushes are connected to the surface of the light-transmitting protective cover 301 .

[0051] First docking blocks 306 are installed at both ends of the light-transmitting protective cover 301 , and clamping blocks 310 are installed on the sides of the first docking blocks 306 .

[0052] Second docking blocks 307 are installed at both ends of the optical lens 102 . A clamping slot 309 is formed on the side of the second docking block 307 . The clamping block 310 is installed inside the clamping slot 309 .

[0053] The outer sides of the first docking block 306 and the second docking block 307 are sleeved with limiting sleeves 308 .

[0054] The clamping block 310 is installed inside the clamping slot 309, so that the first docking block 306 and the second docking block 307 can be connected, and the limiting sleeve 308 is sleeved on the outside of the second docking block 307 and the second docking block 307 to optimize the installation and removal operations of the light-transmitting protective cover 301. After the light-transmitting protective cover 301 is installed, it can provide effective protection for the optical lens 102 to prevent dust and debris from accumulating on the optical lens 102.

[0055] Dust may also accumulate on the light-transmitting protective cover 301. In order to prevent the dust accumulation on the light-transmitting protective cover 301 from affecting the data collection of the optical sensor 101, a corresponding cleaning brush holder 302 and a cleaning brush are provided. When dust accumulates on the light-transmitting protective cover 301, the telescopic rod can be activated to extend and retract, thereby pushing the moving block 304 to drive the cleaning brush holder 302 to move inside the moving groove 303, so that the cleaning brush holder 302 can effectively clean the dust and impurities on the surface of the light-transmitting protective cover 301, thereby ensuring the cleanliness of the light-transmitting protective cover 301, improving the clarity and light transmittance of the light-transmitting protective cover 301, and thereby improving the detection accuracy of the optical sensor 101.

[0056] It also includes a positioning component, which is arranged on the power grid equipment line to locate the position of the power grid equipment line.

[0057] The positioning component may be a reflective marker, a lens or other element, which can cooperate with the detection light emitted by the optical sensor 101 to monitor the line position of the power grid equipment.

[0058] When installing common power grid equipment line spatial position sensing devices, in order to achieve accurate power grid equipment line position monitoring, most of them need to select the existing features of the power grid equipment line, so as to identify the identity of the power grid equipment line through the features and ensure the accuracy of the monitoring results. This also means that the installation position of the power grid equipment line spatial position sensing device must be near the corresponding feature position, and the installation position is limited.

[0059] The method of using the positioning component to reflect the position of the power grid equipment line frees up the installation position of the sensor component 1. The positioning component represents the identity of the power grid equipment line. The adjustability of the installation position of the positioning component can reduce the requirements for the installation position of the power grid equipment line spatial position sensor device, and further reduce the installation difficulty of the power grid equipment line spatial position sensor device.

[0060] Embodiment 2:

[0061] Working method of the spatial position sensing device of the power grid equipment line, such as Figure 7 As shown, including:

[0062] Arrive at the power grid equipment line, select a positioning point, and set the positioning component on the positioning point;

[0063] Fix the sensor component 1 through the mounting component 2, and establish a matching relationship between the sensor component 1 and the positioning component;

[0064] The sensor component 1 monitors the position fluctuation of the power grid equipment line in real time according to the corresponding positioning component;

[0065] When position fluctuations of power grid equipment lines are detected, an alarm is issued based on the corresponding positioning points.

[0066] For the selection of positioning points, the scope and key locations that need to be monitored can be determined based on the actual needs and monitoring requirements of the power grid equipment lines to ensure that the selected locations can fully cover the line sections that need to be monitored and avoid blind spots.

[0067] When selecting a positioning point, it is also necessary to further analyze the environmental conditions of the selected location, such as temperature, humidity, etc., to ensure that the positioning component can be stably and reliably installed at the positioning point and accurately reflect the location of the power grid equipment line. After determining the positioning point and completing the installation of the positioning component, the location coordinates of the current positioning point can be obtained and recorded through positioning modules such as GPS and Beidou.

[0068] After the sensor component 1 is fixed, it is matched with the positioning component arranged on the power grid equipment line to be monitored to realize the position monitoring of the power grid equipment line.

[0069] After the components are installed and matched, the optical sensor 101 needs to be calibrated to ensure the accuracy of its measurement results. The calibration process includes zero point calibration, full scale calibration, etc.

[0070] After the calibration is completed, the optical sensor 101 will emit detection light to the positioning component through the optical lens 102. The light will be refracted on the surface of the positioning component. By receiving the refracted light, the location information of the power grid equipment line can be collected.

[0071] The location information of power grid equipment lines can be obtained through the refraction angle and propagation time of the refracted light.

[0072] The refraction angle is related to the position of the positioning component. The optical sensor 101 receives the refracted light and measures the change in the refraction angle. By calculating the relationship between the refraction angle and the position, the specific position of the positioning component can be determined.

[0073] The propagation time of light can also be measured synchronously. By calculating the relationship between the propagation time of light and distance, such as speed of light = distance / time, the distance between the positioning component and the optical sensor 101 can be determined to further supplement the position information of the positioning component.

[0074] By comparing the position information collected before and after, it is possible to identify the position fluctuation of the power grid equipment line and issue an alarm in time. And due to the matching relationship between the sensor component 1 and the positioning component, the positioning point with position fluctuation can be quickly determined, thereby determining the specific location of the position fluctuation, issuing an alarm, and improving the subsequent maintenance efficiency.

[0075] The sensor component 1 monitors the position fluctuation of the power grid equipment line in real time according to the corresponding positioning component, including:

[0076] The sensor component 1 collects the position information of the corresponding positioning component in real time;

[0077] Compare the position information at the preset time points and calculate the fluctuation parameters;

[0078] When the fluctuation parameter exceeds a preset threshold, it is determined that there is position fluctuation.

[0079] Due to the influence of the optical sensor 101 and environmental factors, the received signal may contain noise. Therefore, after collecting the position information, the collected data is subjected to noise reduction processing to improve the data quality.

[0080] In the process of continuous data collection, the position information at different time points can be compared to identify the position fluctuation of the positioning component. The fluctuation parameter can be a statistical quantity such as the standard deviation and variance of the position information.

[0081] When the fluctuation parameter exceeds the preset threshold, it is judged that there is position fluctuation, and then a corresponding alarm is issued according to the position coordinates of the corresponding positioning point, so as to realize the rapid maintenance of the power grid equipment line.

[0082] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
