Description

Technical Field

[0001] The utility model relates to the technical field of 10kV cables, in particular to a 10kV overhead hidden danger early warning and precise positioning device. Background Art

[0002] In the power transmission system, 10kV overhead lines play a vital role. Their stability and safety are directly related to the overall operation quality of the power grid and the electricity experience of the majority of users. However, strong winds often pose severe challenges to such lines.

[0003] Strong winds may not only cause the lines to dance, leading to mutual friction and collision between the lines, but may also cause drastic changes in line tension and even cause line breakage, thereby triggering power outages and a series of safety accidents.

[0004] To cope with the impact of strong winds on overhead lines, traditional practices rely mainly on manual inspections and simple meteorological monitoring. However, manual inspections are often limited by the number of personnel and inspection frequency, making it difficult to detect and handle line faults in a timely manner, resulting in delayed early warnings. In addition, due to the lack of accurate positioning methods, once a line fault occurs, maintenance personnel often find it difficult to quickly determine the fault location, resulting in slow response speed and low maintenance efficiency.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 - Figure 3 The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, including a rotating plate 6, a through hole 17 is opened at the center of the surface of the rotating plate 6, a connecting column 9 is fixedly installed on the inner wall of the through hole 17, a spring 13 is provided on the outer wall of the connecting column 9, the bottom of the spring 13 is fixedly connected to the top of the rotating plate 6, and a hollow column 10 is fixedly installed on the end of the spring 13 away from the rotating plate 6, a lower pressure chamber 11 is fixedly installed on the outer wall of the top of the hollow column 10, a locator 12 is fixedly installed on the top of the lower pressure chamber 11, an elastic band 16 is fixedly connected to the outer wall of the hollow column 10, and a slider 8 is fixedly connected to the other end of the elastic band 16, and the slider 8 is slidably installed on the surface of the rotating plate 6.

[0022] It should be noted that: when wind acts on the fan blade 7, the rotating plate 6 starts to rotate. Due to the centrifugal force, the slider 8 is thrown to the edge of the rotating plate 6, and the elastic belt 16 is stretched. As the slider 8 moves, the elastic belt 16 is further stretched, generating a downward pulling force on the hollow column 10. At this time, the spring 13 begins to be compressed. When the wind force is strong enough, the lower pressure chamber 11 moves downward under the combined action of the wind pressure and the tension of the elastic belt 16. When the button 23 at the bottom of the lower pressure chamber 11 contacts the top of the connecting column 9, the positioner 12 is triggered, sending a positioning signal and a wind force signal.

[0023] Furthermore, by driving the rotating plate 6 to rotate through wind power, the dual effects of centrifugal force and wind pressure are utilized to enable the lower pressure bin 11 and the positioner 12 to quickly respond to wind changes, thereby achieving timely early warning and accurate positioning of hidden dangers.

[0024] See also Figure 2 The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, including a sliding groove 14 at both ends of the surface of a rotating plate 6, the inner wall of the sliding groove 14 is slidably connected to the outer wall of the slider 8, and the side walls at both ends of the rotating plate 6 are clamped with fan blades 7.

[0025] It should be noted that the fan blades 7 are located at both ends of the rotating plate 6, which can fully utilize the wind resources. The larger force-bearing area makes it easier for the fan blades 7 to capture the wind and convert it into power for the rotation of the rotating plate 6.

[0026] Furthermore, the fan blades 7 are connected to the rotating plate 6 by a snap-fit ​​method. This connection method is simple and firm, and can ensure that the fan blades 7 stably drive the rotating plate 6 to rotate under the action of wind. At the same time, the snap-fit ​​method also makes it easy to replace fan blades 7 of different sizes in different regions.

[0027] See also Figure 3 The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, including a fixed plate 24 fixedly installed at the bottom of the lower pressure chamber 11, the inner wall of the fixed plate 24 is clamped with the top of the hollow column 10, the outer wall of the lower pressure chamber 11 is provided with a spoiler grille 22, and the top of the inner wall of the lower pressure chamber 11 is fixedly installed with a button 23.

[0028] It should be noted that the spoiler grille 22 opened on the outer wall of the lower pressure bin 11 can increase wind resistance, making the lower pressure bin 11 more susceptible to wind force. When wind force acts on the spoiler grille 22, a downward pressure will be generated, pushing the lower pressure bin 11 and its hollow column 10 to move downward, thereby improving the device's response sensitivity to wind force and ensuring that the positioner 12 can be triggered in time when the wind force is strong enough.

[0029] See also Figure 2 The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, including a slider 8 with a fixed block 15 fixedly installed on the top, an elastic band 16 fixedly installed on the outer wall of the fixed block 15, and an end of the elastic band 16 away from the fixed block 15 fixedly connected to a connecting block 21, and the side wall of the connecting block 21 is fixedly installed on the outer wall of the hollow column 10.

[0030] It should be noted that the tension of the elastic belt 16 can be adjusted by adjusting the position between the fixing block 15 and the connecting block 21 or replacing the elastic belt 16 with different elasticity, so that the device can be flexibly adjusted according to different wind conditions and working environments to ensure optimal transmission efficiency and response speed.

[0031] See also Figure 2 The utility model provides a technical solution: a 10kV overhead hidden danger warning and precise positioning device, including a bolt 18 installed on the surface of a rotating plate 6, and the bottom outer wall of the bolt 18 is threadedly connected to a threaded hole 19 opened on the surface of a turntable 20.

[0032] It should be noted that the threaded connection between the bolt 18 and the threaded hole 19 makes the installation process simple and efficient. The rotating plate 6 and the turntable 20 can be tightly connected by simply screwing the bolt 18 into the threaded hole 19.

[0033] See also Figure 1The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, including a turntable 20 with a power generation compartment 5 rotatably installed at the bottom, and a fixed column 4 fixedly installed at the bottom of the power generation compartment 5.

[0034] It should be noted that when the turntable 20 rotates due to the action of wind, this rotational force can be converted into electrical energy in the power generation compartment 5, so that the device can use the energy in the external environment to generate electricity by itself. Even in the absence of an external power supply, the locator 12 can still send signals normally through the electricity provided by the power generation compartment 5.

[0035] See also Figure 1 The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, comprising a fixing column 4 with a connecting plate 3 fixedly installed at the bottom, and a base 1 fixedly installed at the bottom of the connecting plate 3.

[0036] See also Figure 1 The utility model provides a technical solution: a 10kV overhead hidden danger early warning and precise positioning device, comprising a base 1 with a plurality of connection holes 2 opened on the surface, and the connection holes 2 are evenly distributed on the surface of the base 1 in a circular shape.

[0037] It should be noted that the connection holes 2 are evenly distributed around the circumference, which allows the base 1 to be subjected to more uniform force when connected to other components, avoiding structural deformation or damage caused by uneven force, enhancing the structural strength of the base 1, and improving the stability and reliability of the connection.

[0038] Working principle: When wind acts on the fan blades 7, the fan blades 7 capture the wind force and convert it into power for the rotation of the rotating plate 6. As the rotating plate 6 rotates, due to the action of centrifugal force, the slider 8 is thrown to the edge of the rotating plate 6, and the elastic band 16 is stretched, generating a downward pulling force on the hollow column 10, driving the slider 8 to move. The elastic band 16 is further stretched, generating a continuous pulling force on the hollow column 10. At this time, the spring 13 begins to be compressed. When the lower pressure chamber 11 is subjected to the combined action of wind pressure and the tension of the elastic band 16, the lower pressure chamber 11 and its hollow column 10 move downward, and the turntable 20 is connected to the rotating plate 6. When the rotating plate 6 rotates, the turntable 20 also rotates accordingly. This rotational force can be converted into electrical energy in the power generation chamber 5, enabling the device to use energy from the external environment to generate electricity. When the button 23 at the bottom of the lower pressure chamber 11 contacts the top of the connecting column 9, the locator 12 is triggered. At this time, the locator 12 uses the electricity provided by the power generation chamber 5 to send a positioning signal and a wind signal, realizing timely warning and accurate positioning of hidden dangers.
