Description

Technical Field

[0001] This invention relates to the field of substation technology, specifically to the field of internal monitoring technology for substations, and particularly to a mobile substation electrical equipment monitoring device. Background Technology

[0002] A mobile substation is an integrated, rapidly deployable power supply device primarily used for temporary or emergency power supply scenarios. It integrates transformers, high-voltage switchgear, low-voltage power distribution systems, and control systems onto a mobile platform (such as a trailer, container, or vehicle-mounted unit), offering advantages such as high flexibility, easy installation, and reusability.

[0003] Based on the search of substation monitoring data, some existing technologies were discovered, which will be introduced one by one:

[0004] Firstly, the Chinese utility model patent with authorization announcement number CN207994723U discloses a multi-functional mobile substation electrical equipment monitoring device, which is used for monitoring potential equipment or parts in substations of various levels in the power system. It monitors the slow changing trend of potential equipment hazards, so that the equipment is not shut down before the potential hazard reaches the defect, thus ensuring the reliability of power supply for users. In addition, it can reduce manpower and increase efficiency. However, it has some shortcomings. For example, it captures and maintains images through a camera, but it requires personnel to carry it to complete the inspection, which is not automated enough.

[0005] Secondly, the Chinese utility model patent with authorization announcement number CN215498618U discloses a panoramic monitoring device for power transmission and transformation equipment in substations. It is configured with a first motor, a cylinder, a second motor, and a main gear. The second motor and the main gear work together to start the second gear and drive the main gear to rotate, thereby causing the cylinder to drive the monitoring device body to rotate. The cylinder and the first motor work together to start the first motor and drive the square cylinder to rotate, thereby adjusting the monitoring angle of the monitoring device body. This allows the monitoring device body to monitor from multiple angles, thus eliminating the need to install multiple monitoring devices and avoiding the waste of a lot of financial and material resources. However, there are many electrical components inside the substation. Although the monitoring angle of this monitoring device is adjustable, there are still blind spots in the monitoring.

[0006] Based on the above problems, the present invention proposes a mobile substation electrical equipment monitoring device. Summary of the Invention

[0007] To address the issues of insufficient automation in monitoring electrical components within substations, as mentioned in the background, and the existence of blind spots in monitoring, this invention provides a mobile substation electrical equipment monitoring device.

[0008] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0009] A mobile substation electrical equipment monitoring device includes a monitoring mechanism installed inside the substation body. The monitoring mechanism includes a square frame bracket installed inside the substation body and close to the upper end of the substation body. A monitoring component is installed on the square frame bracket. The monitoring component includes four retraction and extension units located at the four right angles of the square frame bracket and a suspended bracket located inside the square frame bracket and at the same height as the square frame bracket. The retraction and extension units are connected to the suspended bracket by a first connecting rope. Four first connecting ropes are provided. By coordinating the retraction and extension of the four first connecting ropes by the four retraction and extension units, the suspended bracket can move in a planar coordinate system.

[0010] A monitoring element is installed on the suspended support via a connecting assembly, and the monitoring element is capable of moving vertically. The connecting assembly includes a second connecting rope with a retractable length, and the second connecting rope is connected to the monitoring element.

[0011] This solution achieves automated, blind-spot-free monitoring of electrical components within the substation by periodically moving the traction monitoring element within a three-dimensional coordinate system. Furthermore, since the traction medium consists of the first and second connecting ropes, a buffering effect is provided if the monitoring element comes into contact with the electrical components during the inspection process, reducing the damage caused to both components.

[0012] As a further improvement and optimization of the present invention, a fixed support is fixedly provided at the right angle of the square frame bracket, and a movable support is hinged at the end of the fixed support. The hinge axis formed at the hinge between the fixed support and the movable support is arranged vertically, and the retraction unit is set on the movable support.

[0013] As a further improvement and optimization of the present invention, the retracting unit includes a fixed outer column arranged vertically and fixedly mounted on a movable support. The interior of the fixed outer column is hollow, and a retracting inner column exists inside the fixed outer column.

[0014] The retractable inner column is hollow inside, and a connecting shaft is fitted inside the retractable inner column via a connector.

[0015] The bottom of the fixed outer column is equipped with a first motor, which is connected to the connecting shaft to form a power connection. The movable support is provided with a rope hole on the side facing the suspended bracket.

[0016] One end of the first connecting rope is connected to the suspended support, and the other end of the first connecting rope passes through the rope hole and is connected to the retractable inner column.

[0017] As a further improvement and optimization of the present invention, a spring is provided below the retractable inner column. When relative displacement occurs between the retractable inner column and the connecting shaft, the two are kept in a dynamic connection through the connecting member.

[0018] As a further improvement and optimization of the present invention, the difference between the inner radius of the fixed outer column and the outer radius of the retractable inner column is equal to the diameter of the first connecting rope.

[0019] As a further improvement and optimization of the present invention, the connector includes an internal spline disposed on the inner column of the receiving and extending mechanism and an external spline disposed on the connecting shaft.

[0020] As a further improvement and optimization of the present invention, the connecting component includes a rope winding reel mounted on the suspended support and a second motor that forms a power connection with the rope winding reel;

[0021] One end of the second connecting rope is connected to the rope reel, and the other end of the second connecting rope is connected to the monitoring element.

[0022] As a further improvement and optimization of the present invention, a horizontally arranged transition roller is provided on the suspended support. There are two transition rollers, and the distance between the two transition rollers is perpendicular to the axis of the transition rollers. The second connecting rope passes through the area between the two transition rollers and is connected to the monitoring element.

[0023] As a further improvement and optimization of the present invention, a battery is also provided on the suspended bracket, which is used to power the second motor and the monitoring element.

[0024] As a further improvement and optimization of the present invention, the battery adopts wireless charging technology. Specifically, a suspension rod is provided on the frame support, a wireless charging transmitter is provided at the end of the suspension rod, and a wireless charging receiver is provided on the upper surface of the suspended support. Wireless charging of the battery is achieved through the cooperation of the wireless charging receiver and the wireless charging transmitter.

[0025] Compared with the prior art, the beneficial effects of this invention are as follows:

[0026] This solution, through the cooperation of four retraction units and connecting components, can use the first and second connecting ropes as traction mediums to move the monitoring element in a three-dimensional coordinate system, thereby realizing the monitoring of electrical components within the substation body. The monitoring can be achieved without blind spots. Furthermore, based on the layout of the electrical components within the substation body, the running trajectory of the monitoring element can be programmed. By controlling the monitoring element to perform periodic inspections through the program, automated monitoring can be achieved, making it easier and less labor-intensive. It should be noted that the programming is achievable with existing technology and will not be elaborated upon.

[0027] Furthermore, the monitoring mechanism of this solution also has the following technical advantages: On the one hand, the four retraction units are arranged vertically in a cylindrical shape and hidden in the corner of the substation body. Only the four first connecting ropes pull the suspended bracket to move, and the connecting components are all located on the suspended bracket. Only the second connecting rope pulls the monitoring element to move. Therefore, it is more compact and does not take up much space. Those skilled in the art can easily imagine that it is similar to the traction technology in 3D printers, which pulls the suspended bracket to move within the coordinate system. However, this technology has the disadvantage of occupying a lot of space. On the other hand, the first and second connecting ropes have flexible properties. If the monitoring element collides with the electrical components in the substation body during the movement of the monitoring element, the flexible traction method of the first and second connecting ropes can play a buffering role and avoid damage to the monitoring element or electrical components.

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0038] Reference Figures 1-7 A mobile substation electrical equipment monitoring device includes a monitoring mechanism installed inside the substation body 100, which enables automated, blind-spot-free monitoring of electrical components within the substation body 100.

[0039] The monitoring mechanism includes a frame bracket 101 located inside the substation body 100 and near the upper end of the substation body 100, and a monitoring component 200 is installed on the frame bracket 101.

[0040] The monitoring component 200 includes four retraction units 203 located at the four right angles of the frame bracket 101, and a suspended bracket 205 located inside the frame bracket 101 and at the same height as the frame bracket 101. The retraction units 203 and the suspended bracket 205 are connected by first connecting ropes 204. Four first connecting ropes 204 are provided. Therefore, by coordinating the retraction and extension of the four first connecting ropes 204 by the four retraction units 203, the suspended bracket 205 can move in the plane coordinate system.

[0041] Specifically, refer to Figures 3-5 A fixed support 201 is fixedly installed at the right angle of the square frame bracket 101, and a movable support 202 is hinged at the end of the fixed support 201, and the hinge axis formed at the hinge between the fixed support 201 and the movable support 202 is arranged vertically.

[0042] The extension / retraction unit 203 is mounted on the movable support 202.

[0043] The retracting unit 203 includes a fixed outer column 2031 arranged vertically and fixedly mounted on the movable support 202. The fixed outer column 2031 is hollow inside. There is a retracting inner column 2034 inside the fixed outer column 2031, and a spring 2035 is provided below the retracting inner column 2034.

[0044] The retractable inner column 2034 is also hollow inside. The connecting shaft 2033 is sleeved inside the retractable inner column 2034 through a connector. When there is relative displacement between the retractable inner column 2034 and the connecting shaft 2033, the two are kept in a dynamic connection through the connector. Preferably, the connector includes an internal spline on the retractable inner column 2034 and an external spline on the connecting shaft 2033.

[0045] A first motor 2032 is provided at the bottom of the fixed outer column 2031, and the first motor 2032 and the connecting shaft 2033 form a power connection.

[0046] The movable support 202 has a rope hole 2021 on the side facing the suspended bracket 205.

[0047] One end of the first connecting rope 204 is connected to the suspension bracket 205, and the other end of the first connecting rope 204 passes through the rope hole 2021 and is connected to the retractable inner column 2034.

[0048] The difference between the inner radius of the fixed outer column 2031 and the outer radius of the retractable inner column 2034 is equal to the diameter of the first connecting rope 204.

[0049] The working process of the take-up and take-down unit 203 is specifically manifested as follows:

[0050] The first motor 2032 drives the connecting shaft 2033 to rotate. The connecting shaft 2033 rotates together with the inner column 2034 through the connector, thereby causing the inner column 2034 to rotate to either retract or release the rope. The former will retract the first connecting rope 204, and the latter will release the first connecting rope 204. This is the working process of a single retraction unit 203. Through the cooperation of four retraction units 203, the purpose of moving the traction suspension bracket 205 in the plane coordinate system can be achieved.

[0051] Furthermore, during the rope winding process, since the difference between the inner radius of the fixed outer column 2031 and the outer radius of the winding inner column 2034 is equal to the diameter of the first connecting rope 204, as the first connecting rope 204 winds around the winding inner column 2034, the portion of the first connecting rope 204 that is about to be retracted onto the winding inner column 2034 will cause the winding inner column 2034 to move downward under the pressure of the portion that has already been retracted onto the winding inner column 2034, and the spring 2035 will be compressed, thereby achieving the purpose of orderly winding the first connecting rope 204 onto the winding inner column 2034. Its technical advantage is that the structure is simple and the size of the retraction or release can be precisely controlled during rope winding and release, thereby making the movement accuracy of the suspension bracket 205 higher.

[0052] In addition, when releasing the rope, the spring 2035 will release its elasticity, thereby ensuring that the first connecting rope 204 is orderly wound on the inner column 2034 whether the rope is being pulled up or released.

[0053] In addition, the technical advantages of using four retraction units 203 to move the suspended support 205 within a planar coordinate system are as follows: Firstly, the four retraction units 203 are arranged vertically in a cylindrical shape and are hidden in the corner of the substation body 100. Only the four first connecting ropes 204 externally pull the suspended support 205 to move. Therefore, it is more compact and space-saving. Those skilled in the art can easily imagine that it is similar to the traction technology in 3D printers, which pulls the suspended support 205 to move within a coordinate system. However, this technology has the disadvantage of occupying a large space. Secondly, the first connecting ropes 204 have flexible properties. During the movement of the suspended support 205, if the monitoring element 207 collides with the electrical components inside the substation body 100, the flexible traction of the first connecting ropes 204 can play a buffering role and prevent damage to the monitoring element 207 or the electrical components.

[0054] Reference Figure 6 The suspended bracket 205 is equipped with a monitoring element 207 via a connecting component, and the monitoring element 207 can move in the vertical direction. The monitoring element 207 can be implemented using existing technologies, such as a combination of camera technology and sensor technology, etc., which is not the core of this solution and will not be elaborated here.

[0055] Furthermore, refer to Figure 6 and Figure 7 The connecting assembly includes a rope reel 209 and a transition roller 211 mounted on a suspended bracket 205. The transition roller 211 is arranged horizontally and there are two of them. The distance between the two transition rollers 211 is perpendicular to the axis of the transition roller 211.

[0056] The connecting assembly also includes a second connecting rope 208 and a second motor 210 that is poweredly connected to the rope winding reel 209.

[0057] One end of the second connecting rope 208 is connected to the rope reel 209, and the other end of the second connecting rope 208 is connected to the monitoring element 207 after passing over the area between the two transition rollers 211.

[0058] The working process of the connecting component is specifically manifested as follows:

[0059] The second motor 210 drives the rope reel 209 to rotate to retract or release the rope, thereby retracting or releasing the second connecting rope 208, making the height of the monitoring element 207 higher or lower. In conjunction with the planar coordinate system movement of the suspension bracket 205, the monitoring element 207 can move in the three-dimensional coordinate system.

[0060] Similarly, the traction method of the connecting components, in which only the second connecting rope 208 externally pulls the monitoring element 207, also has the effect of not occupying space and providing cushioning.

[0061] Furthermore, a battery is also provided on the suspended bracket 205 to power the second motor 210 and the monitoring element 207, and the wire between the battery and the monitoring element 207 can be installed in the second connecting rope 208.

[0062] In addition, a suspension rod 102 is provided on the frame bracket 101, and a wireless charging transmitter 103 is provided at the end of the suspension rod 102. A wireless charging receiver 206 is provided on the upper surface of the suspended bracket 205. By pulling the suspended bracket 205 to move, the wireless charging receiver 206 is positioned directly below the wireless charging transmitter 103. The wireless charging technology formed by the cooperation of the two realizes the charging of the battery. It should be noted that the wireless charging technology is existing technology and will not be described in detail.

[0063] Working principle of the invention:

[0064] With the cooperation of four retractable units 203 and connecting components, the first connecting rope 204 and the second connecting rope 208 can be used as traction medium to move the monitoring element 207 in the three-dimensional coordinate system, thereby realizing the monitoring of electrical components in the substation body 100. The monitoring can be achieved without blind spots. Furthermore, according to the layout of electrical components in the substation body 100, the running trajectory of the monitoring element can be programmed. By controlling the monitoring element 207 to perform periodic inspections through the program, automated monitoring can be achieved, which is easier and less labor-intensive. It should be noted that the programming of the program is achievable with existing technology and will not be elaborated here.

[0065] Furthermore, it also possesses the following technical advantages: On the one hand, the four retraction units 203 are arranged vertically in a cylindrical shape and are hidden in the corner of the substation body 100. Only the four first connecting ropes 204 are used to pull the suspended bracket 205 to move, and the connecting components are all located on the suspended bracket 205. Only the second connecting rope 208 is used to pull the monitoring element 207 to move. Therefore, it is more compact and does not take up much space. Those skilled in the art can easily imagine that it is similar to the traction technology in 3D printers, which pulls the suspended bracket 205 to move within the coordinate system. However, this technology has the disadvantage of occupying a large space. On the other hand, the first connecting ropes 204 and the second connecting ropes 208 have flexible properties. During the movement of the monitoring element 207, if the monitoring element 207 collides with the electrical components inside the substation body 100, the flexible traction of the first connecting ropes 204 and the second connecting ropes 208 can play a buffering role and prevent damage to the monitoring element 207 or the electrical components.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
