Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power line measurement technology, specifically relating to a multifunctional power line measuring instrument. Background Technology
[0002] The measurement and collection of information data during the construction of power transmission lines involves multiple operational stages, including surveyors locating design points in the field, collecting geographical information of each point, calculating the boundaries of safe passages, recording features within the passage range, measuring foundation pits, calculating and setting out tower guy wire pits, calculating and setting out the installation positions of spacers during stringing construction, as well as area measurement and road measurement. Therefore, a multi-functional power line measuring instrument is required during the construction of power lines.
[0003] During the survey and design phase of power line engineering, designers need to measure the length of the line path. Traditional wheeled distance measuring instruments mostly use mechanical rollers with counter structures, which have limited functions and have the following defects: they only support horizontal straight line measurement and cannot simultaneously acquire slope or angle data; they lack data recording functions, rely on manual copying which is prone to errors; they have no data output interface, making it difficult to perform numerical processing; they cannot locate the path position, relying on manual recording and map lookup, which is time-consuming and laborious. At the same time, in the actual survey process, there are also situations where traditional measuring instruments cannot help determine whether the cable laying scheme is feasible, making it difficult to confirm the design scheme. When new cables need to be jacked across rivers, the depth of the river cannot be verified. When laying new cables using existing cable wells, the conditions inside the existing cable wells cannot be verified, such as whether there are usable cable duct channels. Utility Model Content

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0027] Example 1
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a multifunctional power line measuring instrument includes a measuring instrument pole 2. The measuring instrument pole 2 has a hollow internal structure with grooves on both sides. A telescopic cylinder 103 extending to the outside of the measuring instrument pole 2 is slidably fitted inside the measuring instrument pole 2. Through the structural design of the measuring instrument pole 2 and the telescopic cylinder 103, the telescopic cylinder 103 and its components can be easily stored. At the same time, the grooves on both sides leave a gap between the telescopic cylinder 103 and the outside of the telescopic cylinder 103, which is convenient for the subsequent routing of transmission lines. A button insertion hole 102 is reserved on the top of the outer side of the telescopic cylinder 103. A cover-lifting rod 100 extending to the outside of the measuring instrument pole 2 is slidably connected to the top of the telescopic cylinder 103. The top of the cover-lifting rod 100 has a circular structure design, which facilitates the subsequent opening of the cable well cover. Both the cover-lifting rod 100 and the telescopic cylinder 103 have evenly distributed scale lines on their outer sides. The design of the scale lines, combined with the extension of the telescopic cylinder 103 and the cooperation of the cover-lifting rod 100, facilitates subsequent measurement of the line. The telescopic cylinder 103 is made of high-strength alloy material, which improves the overall load-bearing capacity of the telescopic cylinder 103 and facilitates the opening of the cable manhole cover. The top and bottom of the outer side of the cover-lifting rod 100 are fixedly installed with push-button 101 that cooperate with the button insertion hole 102. When the push-button 101 is pressed and disengaged into the button insertion hole 102, the limiting and fixing operation of the cover-lifting rod 100 can be released. The measurement work can be easily carried out by pulling out the cover-lifting rod 100. The above structural design facilitates the line measurement when unfolded and the opening of the cable manhole cover when stored, ensuring the flexibility and versatility of the line measuring instrument in later operation.
[0029] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, a U-shaped fixing frame 6 is fixedly installed at the bottom of the measuring instrument rod 2. A roller 5 is rotatably installed on the inner side of the U-shaped fixing frame 6. Through the installation design of the roller 5, the wheel contact measurement function of the power line measuring instrument can be realized. The accuracy in the normal mode is ±0.5%. This mechanism design can realize roller measurement work, which is convenient for subsequent tilt measurement operations. A sealed chamber 400 is threadedly fixed to one side of the U-shaped fixing frame 6. A GPS locator 401, a transmitter 402 and a gyroscope 403 that cooperate with the roller 5 are fixedly installed inside the sealed chamber 400. The gyroscope 403 is a MEMS model with a range of ±30°. The top of one side of the measuring instrument rod 2 is fixed. A deformable handle 700 is installed, and a protective compartment is fixedly installed at the end of the deformable handle 700. An OLED touch screen 701 is fixedly installed inside the protective compartment and placed outside it. The OLED touch screen 701 is equipped with a main control system, with a built-in main control chip and storage module. At the same time, the OLED touch screen 701 has a charging port 702 and a transmission port 703 extending to the outside of the protective compartment. The charging port 702 is a Type-C interface, and the transmission port 703 is a USB interface. The GPS locator 401, the transmitter 402, and the gyroscope 403 are all connected to the OLED touch screen 701 through the internal space of the measuring instrument rod 2 via transmission lines.
[0030] It should be noted that this multifunctional power line measuring instrument can locate the site using a GPS locator 401 during the line measurement process. The location information is then transmitted to the main control system built into the OLED touch screen 701 via a transmitter 402. The main control system then transmits the information to a mobile terminal and creates a map within the main control system to form a trajectory, which is convenient for later export to assist designers in drawing. In addition to conventional mechanical counting to measure horizontal distance, when the newly built line channel has a slope, the gyroscope 403 measures the tilt angle and other related data and transmits them to the main control system within the OLED touch screen 701 for storage, which is convenient for later export to assist designers in verifying the laying channel type and line length.
[0031] When the route plan involves utilizing existing cable wells and cable channels, the cover-lifting rod 100 can be pulled out from the inside of the measuring instrument rod 2 in conjunction with the telescopic joint 103 to open the cable well cover to check the condition inside the well (whether there is water accumulation or blockage, etc.) and verify whether there is an existing cable channel that can be used. This helps to confirm whether the route laying plan is feasible and reduces design changes due to insufficient preliminary survey conditions. At the same time, the telescopic joint 103 is made of high-strength alloy material, which reduces its own weight while meeting the requirements of opening heavy cable well covers, increasing portability. The bottom structure of the cover-lifting tool is matched with the standard cable well cover hole of the power grid, which can be used directly. The sliding groove gap space opened inside the measuring instrument rod 2 can realize the wiring of the transmission line and realize the connection and use of the OLED touch screen 701 with the GPS locator 401, the transmitter 402 and the gyroscope 403. The hollow structure design inside the measuring instrument rod 2 can realize quick storage.
[0032] The lifting rod 100 is telescopic. When the route of the newly built cable channel encounters a river that needs to be jacked, the telescopic section cylinder can be released by pressing the button on the lifting rod 100. The telescopic section cylinder 103 and the tool itself are marked with graduations, which can meet the depth measurement needs of conventional small rivers and can help determine whether the pipeline jacking scheme is feasible and reduce design changes caused by insufficient preliminary survey conditions.
[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
