Description

Technical Field

[0001] The utility model relates to the technical field of distribution facility installation, and particularly relates to an overhead distribution line length measuring device. Background Technique

[0002] Overhead lines mainly refer to overhead open wires, which are erected above the ground. They are transmission lines that use insulators to fix transmission wires on poles standing upright on the ground to transmit electric energy. They are relatively convenient for erection and maintenance, and have low costs. However, they are easily affected by meteorology and the environment, resulting in failures. At the same time, the entire transmission corridor occupies a large amount of land area and is prone to causing electromagnetic interference to the surrounding environment.

[0003] For example, an overhead distribution line length measuring device disclosed in the publication number "CN222297442U". When the overhead distribution line length measuring device needs to collect data at another measuring point, by pulling the pull rings on both sides, the connecting rod and the plug rod are driven to move, so that the plug rod moves away from the jack, facilitating the unlocking of the locking structure and separating the adjusting support frame and the protective box body, which is beneficial to improving the convenience of moving and handling the overhead distribution line length measuring device.

[0004] In the actual use process, the operator needs to pull the pull rings with both hands to release the locking structure before the protective box body can be taken. At this time, another staff member is required to assist in the operation. If the pull rings are released, the protective box body will be locked again, making it difficult for a single person to operate. Moreover, during the measurement process, it is necessary to ensure that the device is in a horizontal state. When outdoors, it is impossible to ensure that the ground is flat, and the device does not have a corresponding leveling mechanism. This leads to the need for staff to find a relatively flat ground for placement before operation, and there are certain drawbacks in use. Therefore, we propose an overhead distribution line length measuring device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an overhead distribution line length measuring device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An overhead distribution line length measuring device, including an adjusting support frame and a protective box body. A detection device body and an information processing module are placed inside the protective box body. The adjusting support frame is composed of a telescopic rod and a locking bolt. A support structure is arranged at the bottom of the telescopic rod, and a placement mechanism is arranged at the top of the telescopic rod. The placement mechanism includes:

[0007] A clamping plate for clamping and fixing the protective box body;

[0008] Fixed rubber bumps for slowing down the reset speed of the clamping plate in cooperation with the abutting rubber bumps;

By rotating the adjusting screw rod to resist the placing plate and observing the level bubble, the placing plate can be adjusted to a horizontal state, so that it is convenient to use the detection device body to detect the long fixed-point position and height data of the power distribution line, and cooperate with the information processing module to perform data statistics and storage. There is no need for the staff to find a relatively flat ground, which is convenient to use. When it is necessary to release the fixation of the protection box body, just pull the clamping plate. When the clamping plate drives the resisting rubber bump to move to the position of the fixing rubber bump, the resisting rubber bump abuts against the fixing rubber bump to impose a certain restriction on the clamping plate and slow down the speed of the clamping plate resetting under the action of the reset spring. At this time, the staff has enough time to remove the protection box body from the top of the placing plate, which is convenient to use. When it is necessary to fix, just pull the clamping plate to move to the side away from the center of the placing plate, place the protection box body on the top of the placing plate, and after the clamping plate resets under the action of the reset spring, the clamping plate can clamp and fix the protection box body to ensure the stability of the detection device body and the information processing module during use.

The vertical rod can then push the propping rod to open through the support rod, facilitating the erection of the whole device. When not in use, just rotate the threaded block in the reverse direction to control the threaded block to move upward, and the propping rod can be controlled to retract. Due to the self-locking property of the threaded connection between the threaded block and the threaded sleeve, it is convenient for the staff to carry the adjusting support frame.

Specific embodiments

[0024] As Figures 1-7 shown, the present utility model provides a technical solution: an overhead distribution line length measuring device, which includes an adjusting support frame and a protective box body 2. A detection device body 5 and an information processing module 6 are placed inside the protective box body 2. The adjusting support frame is composed of a telescopic rod 11 and a locking bolt 12. A support structure 3 is arranged at the bottom of the telescopic rod 11, and a placing mechanism 4 is arranged at the top of the telescopic rod 11. The placing mechanism 4 includes: a clamping plate 41, a fixed rubber bump 42, an abutting rubber bump 43, an adjusting screw 44, a fixing plate 45, a support rod 46, a placing plate 47, a return spring 48, and a horizontal bubble level 49.

[0025] A fixing plate 45 is fixed at the top of the telescopic rod 11. A support rod 46 is fixed at the top of the fixing plate 45. The top of the support rod 46 is circular. A placing plate 47 is arranged at the top of the support rod 46. A circular groove is formed at the bottom of the placing plate 47. The top of the support rod 46 is clamped in the circular groove at the bottom of the placing plate 47. A sliding groove is formed at the top of the placing plate 47. A clamping plate 41 is slidably installed in the sliding groove at the top of the placing plate 47. A reset spring 48 is fixed on one side of the clamping plate 41 close to the center of the placing plate 47. The end of the reset spring 48 away from the clamping plate 41 is fixed in the sliding groove at the top of the placing plate 47. A resisting rubber bump 43 is fixed on the surface of the clamping plate 41. A fixing rubber bump 42 is fixed in the sliding groove at the top of the placing plate 47. An adjusting screw rod 44 penetrates through the fixing plate 45 and is in threaded connection with the fixing plate 45. A horizontal bubble level 49 is arranged at the top of the placing plate 47. By rotating the adjusting screw rod 44 to resist the placing plate 47 and observing the horizontal bubble level 49, the placing plate 47 can be adjusted to a horizontal state, so that it is convenient to use the detection device body 5 to detect the long fixed-point position and height data of the power distribution line, and cooperate with the information processing module 6 to conduct data statistics and storage. There is no need for the staff to find a relatively flat ground, which is convenient to use. When it is necessary to release the fixation of the protective box body 2, only need to pull the clamping plate 41. When the clamping plate 41 drives the resisting rubber bump 43 to move to the position of the fixing rubber bump 42, the resisting rubber bump 43 abuts against the fixing rubber bump 42 to impose a certain restriction on the clamping plate 41 and slow down the speed of the clamping plate 41 resetting under the action of the reset spring 48. At this time, the staff has sufficient time to remove the protective box body 2 from the top of the placing plate 47, which is convenient to use. When it is necessary to fix, only need to pull the clamping plate 41 to move away from the center of the placing plate 47, place the protective box body 2 on the top of the placing plate 47. After the clamping plate 41 resets under the action of the reset spring 48, the clamping plate 41 can clamp and fix the protective box body 2 to ensure the stability when the detection device body 5 and the information processing module 6 are used.

[0026] Among them, the detection device body 5 is an infrared measuring instrument, and the information processing module 6 is a microcomputer. The data measured by the infrared measuring instrument is imported into the microcomputer and converted by the microcomputer to display the actual length of the overhead line on the display screen. This technology is an existing publicly disclosed technology with mature existing products and is not the innovative part of this application. Therefore, it is not elaborated too much in this application.

[0027] The support structure 3 includes a threaded sleeve 31. The top of the threaded sleeve 31 is fixed to the bottom of the telescopic rod 11. A threaded block 32 is threadedly connected to the surface of the threaded sleeve 31. A ring 33 is rotatably installed at the bottom of the threaded block 32. A vertical groove 34 is formed in the side surface of the threaded sleeve 31. The ring 33 passes through the vertical groove 34 and is slidably connected to the vertical groove 34. A vertical rod 35 is fixed to the bottom of the ring 33. A support rod 36 is hinged to the bottom of the vertical rod 35. A support rod 37 is hinged to the bottom of the threaded sleeve 31. One end of the support rod 36 away from the vertical rod 35 is hinged to the support rod 37. When in use, by rotating the threaded block 32, the threaded block 32 is controlled to drive the ring 33 to move downward. The ring 33 drives the vertical rod 35 to move downward together. The vertical rod 35 can push the support rod 37 to open through the support rod 36, facilitating the erection of the whole device. When not in use, just rotate the threaded block 32 in the reverse direction to control the threaded block 32 to move upward, and the support rod 37 can be controlled to fold up. Due to the self-locking property of the threaded connection between the threaded block 32 and the threaded sleeve 31, it is convenient for the staff to carry the adjustment support frame.

[0028] The locking bolt 12 penetrates through the telescopic rod 11 and is threadedly connected to the telescopic rod 11. By adjusting the telescopic rod 11 to extend or shorten, the height of the protective box body 2 can be adjusted. After the adjustment is completed, tighten the locking bolt 12 to limit the telescopic rod 11 and ensure the stability during the measurement process.

[0029] When in use, after the staff carry the device to the designated measurement position, rotate the threaded block 32 to control the threaded block 32 to drive the ring 33 to move downward. The ring 33 drives the vertical rod 35 to move downward together. The vertical rod 35 can push the support rod 37 to open through the support rod 36, facilitating the erection of the whole device.

[0030] At this time, by pulling the clamping plate 41, the clamping plate 41 is moved to the side away from the center of the placing plate 47 until the contact rubber bump 43 abuts against the fixed rubber bump 42. Then the staff release the clamping plate 41 and place the protective box body 2 containing the detection device body 5 and the information processing module 6 on the top of the placing plate 47. The staff only need to slightly push the clamping plate 41, and the clamping plate 41 gradually resets under the action of the return spring 48. The clamping plate 41 clamps the protective box body 2. Observe the level bubble 49 and adjust the placing plate 47 to the horizontal state, so as to conveniently use the detection device body 5 to detect the long fixed-point position and height data of the power distribution line and cooperate with the information processing module 6 to perform data statistics and storage. There is no need for the staff to find a relatively flat ground, and it is convenient to use.

[0031] When it is necessary to release the fixation of the protective box 2, it is only necessary to pull the clamping plate 41. When the clamping plate 41 moves to the position of the fixed rubber protrusion 42 with the resisting rubber protrusion 43, the resisting rubber protrusion 43 resists with the fixed rubber protrusion 42, which imposes certain restrictions on the clamping plate 41, slowing down the speed at which the clamping plate 41 is reset under the action of the reset spring 48. At this time, the staff has sufficient time to remove the protective box 2 from the top of the placement plate 47, and then rotate the threaded block 32 in the opposite direction to control the threaded block 32 to move upward, so as to control the support rod 37 to be retracted. The self-locking property of the threaded connection between the threaded block 32 and the threaded sleeve 31 makes it convenient for the staff to carry the adjustment support frame.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
