[0002] Lightning arresters, as key equipment for overvoltage protection in power systems, have the main function of protecting electrical equipment from high transient overvoltage hazards and effectively limiting the follow-current time and amplitude to ensure stable operation of electrical equipment.

[0003] According to the standards and operation and maintenance specifications of the power industry, in order to ensure the reliable performance of the lightning arrester, it must be removed from the operating equipment and strictly tested before installation or when a diagnostic test is required when a fault occurs in the operating equipment. The lightning arrester can only be used normally if the test data fully meets the standards and is within the specified test cycle.

[0004] In current arrester testing, due to technical limitations, the arrester has a special structure, in which the middle shed is a regular cylinder, the bottom adopts a screw structure, and the whole is conical, which makes it impossible for the arrester to remain stable when placed naturally.

It is difficult to fix and it is difficult to ensure that the arrester is precisely perpendicular to the horizontal plane. According to the "Lean Management Rules for Lightning Arrester Tests 2023 Edition", the data must be accurate and reliable during the test.

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0067] like Figure 1-Figure 2 The present invention proposes an automatic leveling arrester base device, comprising a fixing device 1 and a control system 3. The fixing device 1 is used to fix the arrester, and the control system 3 is used to control the fixing device 1 to ensure that the fixing device 1 is placed horizontally, so as to realize fast and accurate automatic leveling of the fixing device 1 during the arrester test.

[0068] The fixing device 1 comprises a supporting plate 1-1 for installing the fixing parts, an observation window 1-2 for observing whether the bottom of the lightning arrester and the grounding electrode are in good contact is arranged on the side of the supporting plate 1-1, and a placement tube 1-3 for fixing the lightning arrester is arranged at the end of the observation window 1-2. The design of the placement tube 1-3 provides a stable test platform for the lightning arrester, ensuring the safety and accuracy during the test.

[0069] An elastic component 1-4 is arranged inside the observation window 1-2 to adapt to different lightning arresters so that the supporting component of the lightning arrester can be adjusted timely according to the length of the lightning arrester. A placement plate 1-5 is arranged at the end of the elastic component 1-4. The lightning arrester is placed in the placement tube 1-3, and its bottom contacts the placement plate 1-5 to ensure the stable installation of the lightning arrester.

[0070] A telescopic leg 1-6 is arranged between the placement tube 1-3 and the support plate 1-1, and the placement tube 1-3 is connected to the support plate 1-1 through the telescopic leg 1-6. A tilt sensor 1-7 is arranged on the side of the support plate 1-1, and the tilt sensor 1-7 sends the angle data monitored in real time to the control system 3. After receiving these data, the control system 3 starts the corresponding algorithm program to accurately adjust the extended length of the telescopic leg 1-6 until the support plate 1-1 reaches a completely horizontal state, thereby ensuring the level of the support plate 1-1 and ensuring the accuracy of the lightning arrester test.

[0071] The device of the present invention works through the coordinated work of the inclination sensor 1-7 and the telescopic leg 1-6. Specifically, the inclination sensor 1-7 monitors the horizontal state of the support plate 1-1 in real time, and provides accurate data support for the control system 3, thereby realizing accurate adjustment of the extension length of the telescopic leg 1-6, so that the support plate 1-1 can automatically reach and maintain a horizontal state, realizing the automatic leveling function of the support plate 1-1, which not only improves the operating convenience of the device, but also significantly enhances the stability and accuracy of the lightning arrester during use.

[0072] The inclination sensor 1-7 not only has high sensitivity and high precision, but can also send the monitored data to the control system in real time, so that the control system can quickly respond to the inclination changes of the support plate 1-1 and provide key data support for subsequent automatic leveling operations. The instant feedback mechanism greatly shortens the system response time and improves the efficiency of the overall leveling operation.

[0073] A grounding pile 1-8 is arranged on the side of the support plate 1-1, so that the device of the present invention can be easily connected to the grounding system, ensuring a stable and reliable connection between the device of the present invention and the grounding system, providing a solid guarantee for the normal operation of the lightning arrester, while protecting the safety of the testers and improving the safety performance and practicality of the device of the present invention.

[0074] The side of the support plate 1-1 is provided with walking wheels 2 for walking and carrying, which facilitates the movement of the entire device and reduces the carrying pressure of the staff; at the same time, the device can be applied to various complex venues and scenes, improving its practicality and flexibility.

[0075] When conducting a lightning arrester test on site, the lightning arrester is placed in the placement tube 1-3 for testing, and a tilt sensor 1-7 is set on the side of the support plate 1-1. The high-precision tilt sensor 1-7 monitors the angle between the support plate 1-1 and the horizontal plane in real time, thereby accurately sensing the tilt state of the support plate 1-1. The tilt sensor 1-7 sends the monitored data to the control system in real time. The control system accurately calculates whether each telescopic leg 1-6 needs to be adjusted and the height value that needs to be adjusted according to the tilt angle and tilt direction of the support plate 1-1, and controls the telescopic length of each telescopic leg 1-6, so that the support plate 1-1 finally reaches a horizontal state.

[0076] For example, when the fixing device 1 tilts due to uneven placement or the influence of external force, the inclination sensor 1-7 will output a corresponding signal according to the degree of inclination. After receiving the electrical signal, the single-chip microcomputer 3-1 of the control system 3 accurately calculates the height value that needs to be adjusted for each telescopic leg 1-6 according to the inclination angle and direction of the support plate 1-1, and adjusts the extended length of the telescopic leg 1-6 in time, finally making the support plate 1-1 reach a horizontal state, so that the fixing device 1 is level.

[0077] The elastic component 1-4 is placed in the observation window 1-2 to support the whole. The placement tube 1-3 is fixed on the side of the observation window 1-2, which is used to fix the lightning arrester and is the direct contact part of the lightning arrester. The signal sent by the inclination sensor 1-7 is transmitted to the control system 3, and the fixing device 1 is adjusted by the control system 3, thereby achieving the purpose of the fixing device 1 of the automatic leveling lightning arrester test base, so that the operator can quickly perform lightning arrester related tests.

[0078] The device of the present invention has a simple structure. By integrating elastic components, observation windows, placement tubes, inclination sensors and control systems, it is easy and quick to operate, has good stability and strong adaptability, and realizes the automation and intelligence of the fixing device of the lightning arrester test base, which not only reduces the workload of operators but also reduces the impact of improper manual operation on the accuracy and consistency of test data, improves the efficiency and accuracy of the test, and also enhances the stability and durability of the device, providing operators with a more convenient and safe test environment.

[0079] The control system 3 at least includes a single chip microcomputer 3-1, a drive circuit 3-2 and an actuator 3-3, which together realize the automatic control and precise adjustment of the device, thereby improving the stability and reliability of the device and providing a more convenient and efficient test environment for operators.

[0080] The single chip microcomputer 3-1 is responsible for receiving the angle data sent by the inclination sensor 1-7 and processing it quickly and accurately. It outputs the corresponding control signal according to the processing result. The high-performance computing capability and real-time response characteristics of the single chip microcomputer 3-1 ensure the accuracy and timeliness of the control signal, providing a strong guarantee for the stable and reliable operation of the device.

[0081] The drive circuit 3-2 receives the control signal from the microcontroller 3-1 and converts it into a current or voltage signal that can be understood by the actuator 3-3, ensuring that the control signal can be accurately and efficiently transmitted to the actuator, thereby driving it to perform corresponding actions, providing strong support for the rapid response and precise adjustment of the device.

[0082] The actuator 3-3 controls the contraction of the telescopic legs 1-6 according to the signal of the driving circuit 3-2, thereby realizing automatic leveling of the device. The high precision and fast response capability of the actuator 3-3 ensure the accuracy and timeliness of the adjustment operation, so that the device can maintain a stable horizontal state in a complex and changeable test environment.

[0083] The commonly used hardware control systems 3 are PLC, single chip microcomputer 3-1 and industrial computer. After comparative analysis and selection based on indicators such as control mode, power consumption and cost, it is concluded that single chip microcomputer 3-1 has the fastest processing speed, moderate price and is more suitable for the control of the device of the present invention.

[0084] The telescopic leg 1-6 is a hydraulic rod, which is provided with a liquid inlet pipe 1-6-1 for liquid to enter. Correspondingly, the actuator 3-3 at least includes a hydraulic valve 3-3-1 and a hydraulic pump 3-3-2. The hydraulic valve 3-3-1 controls the flow direction of the hydraulic oil. The hydraulic pump 3-3-2 draws hydraulic oil from the oil tank connected to it. The hydraulic oil is pressurized by the hydraulic pump 3-3-2 and enters the liquid inlet pipe 1-6-1 through the transport pipe. The high-efficiency performance and stable output of the hydraulic pump 3-3-2 provide a continuous and stable power source for the hydraulic rod, ensuring the stability and reliability of the device during long-term operation.

[0085] Preferably, a filter is installed between the hydraulic pump 3-3-2 and the oil tank to remove impurities and contaminants in the hydraulic control system. When the hydraulic pump 3-3-2 extracts hydraulic oil from the oil tank and pressurizes and delivers it to the telescopic leg 1-6, the filter can effectively intercept and remove tiny particles, metal debris and other potential contaminants in the oil, preventing impurities from entering the hydraulic valve 3-3-1 and the hydraulic rod, thereby avoiding jamming, wear and even failure, and ensuring the smooth operation of the hydraulic control system. Protecting the normal operation of the hydraulic control system enhances the reliability and durability of the system and extends the service life of various components of the hydraulic control system.

[0086] The filter can be selected from existing filters on the market. Generally, the filter includes a housing, a filter element and a seal. The housing is designed with inlets and outlets, which are connected to the hydraulic pump and the oil tank respectively, so that the oil can be purified through the filter during the circulation process. Among them, the filter housing is made of high-strength, corrosion-resistant materials, such as stainless steel or cast iron, to ensure that the housing can withstand the working pressure of the hydraulic system and the influence of the external environment. The filter element is the core component of the filter, which is composed of multiple layers of filter media, such as metal mesh, fiber material or special synthetic material. The filter element must also have good permeability and pressure bearing capacity to ensure the smooth flow of oil and the normal operation of the system. Seals are provided around the filter inlet and outlet and the filter element to prevent oil leakage.

[0087] In addition, the filter is preferably provided with a bypass valve. When the filter element is clogged and the pressure in the filter increases, the bypass valve automatically opens to allow the oil to continue to flow around the filter element to prevent system overload or filter element damage.

[0088] The walking wheel 2 includes a wheel body 2-1 and a universal connector. The wheel body 2-1 is provided with a connecting hole. A rotating shaft is provided in the connecting hole. Both ends of the rotating shaft are connected to a first hydraulic rod 2-2. The other end of the first hydraulic rod 2-2 is fixed to the side of the support plate 1-1 through a universal connector.

[0089] As another embodiment of the present invention, the hydraulic control system of the actuator 3-3 can also be replaced by an electric push rod, which converts rotary motion into linear motion through a motor-driven screw or gear mechanism, thereby achieving precise control of the telescopic leg 1-6. It has high control accuracy and is easy to integrate with the single-chip computer 3-1.

[0090] As another embodiment of the present invention, the hydraulic control system of the actuator 3-3 can also be replaced by a pneumatic control system, which uses compressed air as a power source and controls the extension and retraction of the telescopic legs 1-6 through a cylinder to achieve rapid adjustment of the height of the device. It has a fast response speed and is suitable for high-frequency operations. It can quickly respond to control signals in a short time to meet the needs of rapid height adjustment. The pneumatic system also has the advantages of simple structure and easy maintenance.

[0091] As another embodiment of the present invention, the hydraulic control system of the actuator 3 - 3 can also be replaced by a mechanical linkage mechanism. Specifically, the mechanical linkage mechanism is driven by a motor or manually, and has high reliability and convenient maintenance.

[0092] As another embodiment of the present invention, the hydraulic control system of the actuator 3-3 can also be replaced by an electromagnetic drive mechanism, which uses the electromagnetic force of an electromagnet or a linear motor to directly drive the movement of the rod to achieve fast and precise control. It has a fast response speed and high control accuracy, and can complete precise adjustments in a short time to meet the needs of high-precision testing.

[0093] The universal connector allows the walking direction of the walking wheel 2 to be adjusted at any time, making the fixing device 1 more flexible when walking. During the test, the operator can easily adjust the walking path of the device according to actual needs, which can meet the needs of the lightning arrester test and ensure that the device can easily cope with various complex terrains and test scenarios.

[0094] In the device of the present invention, two control mechanisms are set for the horizontal adjustment of the support plate 1-1. One is the telescopic leg 1-6 placed between the tube 1-3 and the support plate 1-1, and the support plate 1-1 is adjusted to a horizontal state through the telescopic leg 1-6; the other is the first hydraulic rod 2-2 between the wheel body 2-1 of the walking wheel 2 and the connecting member, and its control system 3 is consistent, and the support plate 1-1 is made to tend to a horizontal state by adjusting the connecting parts of the support plate 1-1.

[0095] The combined use of the two control mechanisms makes the device of the present invention more perfect in terms of horizontal adjustment. Whether through the rapid adjustment of the telescopic legs 1-6 or the precise fine adjustment of the first hydraulic rod 2-2, the height of the support plate 1-1 can be flexibly controlled and precisely adjusted, so that the support plate 1-1 tends to a horizontal state. Not only does it meet the high requirements of the arrester test on the stability of the device, but it also improves the accuracy and safety of the test.

[0096] The observation window 1-2 is used to observe whether the bottom of the lightning arrester and the grounding electrode are in good contact. Therefore, the observation window 1-2 is required to have good light transmittance, and the density cannot be too large so as not to increase the weight of the device being developed. It must also meet the condition of not being easy to break, so as to avoid being easily damaged during use, so as to avoid injuries to the staff when the device of the present invention is broken.

[0097] The observation window 1-2 is made of acrylic material into a tubular structure. The acrylic tube window has a large density, but the best light transmittance, making it easiest to observe the internal structure, and has the best drop resistance. It meets the requirement of not being easy to break while also meeting the light transmittance standard.

[0098] The placement tube 1-3 is used to fix the lightning arrester and is the direct contact part between the lightning arrester and the device of this research and development. The supporting round tube is required to be wear-resistant, firm and have strong supporting force. Therefore, the placement tube 1-3 is made of carbon structural steel into a tubular structure.

[0099] Preferably, the placement pipes 1-3 are made of Q235 carbon structural steel, which has high tensile strength, high yield point and best welding effect.

[0100] The device of the present invention is provided with independently liftable telescopic legs 1-6 on the side of the support plate 1-1, and the height value that needs to be adjusted for each telescopic leg 1-6 is accurately calculated according to the inclination angle and direction of the support plate 1-1, so that the support plate 1-1 is finally brought into a horizontal state.

[0101] At least three telescopic legs 1-6 are provided, and by adjusting the extension lengths of the three telescopic legs respectively, the inclination degree of the support plate 1-1 is accurately controlled to ensure that the support plate 1-1 is placed horizontally, and to ensure that the support plate 1-1 is placed horizontally when the device of the present invention is used.

[0102] In this embodiment, three independently liftable telescopic legs 1-6 are arranged on the side of the support plate 1-1. Based on the three-point support leveling principle, the support plate 1-1 is divided into three equal parts to determine the fixed position of the telescopic legs 1-6, ensuring the precise adjustment of the horizontal degree of the support plate 1-1.

[0103] Hydraulic valve 3-3-1 adopts hydraulic electromagnetic reversing valve, which realizes the reversing control of hydraulic rod through a single liquid inlet hole, greatly simplifying the overall design of hydraulic system. It not only reduces the number of required pipes, joints and valves, but also reduces the complexity and manufacturing cost of the system. At the same time, the simplified design makes the system easier to install, debug and maintain.

[0104] The single chip microcomputer 3-1 sends instructions to the driving circuit 3-2 using control codes written in C language. C language is more suitable for the field of automation, so that the single chip microcomputer 3-1 can quickly and accurately control the extension and retraction of the telescopic leg 1-6.

[0105] Grounding piles 1-8 use terminal-type grounding piles, which have a stable structure and reliable connection. They use sturdy terminals as core components, which can withstand large current shocks and mechanical stresses, ensuring stable grounding connections during long-term use.

[0106] Secondly, the connection method of the terminal post type grounding pile is simple and quick. The terminal post type grounding pile has a deep plug hole, and the handle is made of insulating material, which is safe and reliable, and will not fall off during the wiring process. The operator only needs to wrap the grounding wire firmly around the terminal post and use a special fastening tool to fix it to complete the grounding connection. The connection method is not only simple to operate, but also firmly connected and not easy to loosen, which improves the use efficiency and safety of the device of the present invention.

[0107] In addition, the terminal-type grounding pile also has good corrosion resistance. When used outdoors or in a humid environment, it can effectively resist the erosion of corrosion factors such as moisture and oxygen, and maintain a good state of grounding connection. It extends the service life of the grounding pile, reduces the risk of failure caused by corrosion, and provides a strong guarantee for the long-term stable operation of the device.

[0108] The use of a terminal post type grounding pile as the grounding pile component of the device of the present invention not only improves the stability and reliability of the grounding connection, but also simplifies the connection method, thereby improving the use efficiency and safety of the device of the present invention. At the same time, good corrosion resistance also provides strong support for the long-term stable operation of the device of the present invention.

[0109] The travel wheel 2 includes four universal wheels, which enable the fixture 1 to move in all directions. Whether it is moving forward in a straight line, moving backward, turning left or right, or even rotating on the spot, the fixture 1 can easily cope with it. While improving work efficiency, the device can easily adapt to various complex working environments and ensure the stability of the fixture 1 during movement.

[0110] The support plate 1-1 is used to fix the installation of the support structure to make the device more solid. However, considering the transportation problem, the material density of the support plate 1-1 cannot be too large, otherwise the device is too heavy and inconvenient to carry, and it also needs to have a large compressive strength so that the bottom plate is not easily cracked when drilling holes in the bottom plate.

[0111] Therefore, the support plate 1-1 is made of steel plate. Although the steel plate has the highest Mohs strength and is difficult to process, it has the highest compressive strength and the density meets the requirements.

[0112] Preferably, the steel plate is Q345 steel plate. The yield strength of Q345 steel plate is not less than 345MPa, and the tensile strength is as high as 470~660MPa, which can withstand greater pressure and load to ensure the stability and safety of the structure. In addition, Q345 steel plate is easy to cut, drill, cold bend and other processing, and can meet the needs of various shapes and sizes.

[0113] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.

[0114] Many other changes and modifications may be made without departing from the concept and scope of the present invention.It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
