[0024] The orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "radial", "circumferential", etc. are based on the orientation or position relationship shown in the drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] See also Figure 1 The embodiment of the present application provides an electric power measuring device, including an insulating measuring rope and an insulating clamp 10, the insulating measuring rope includes a main shell 1, a rotating module 2 and an insulating rope 3, the main shell 1 is provided with an installation space 12 inside, and the main shell 1 is provided with an extension hole 13 connected to the installation space 12 on the outside; the rotating module 2 is installed in the installation space 12; one end of the insulating rope 3 is wound around the rotating module 2, and the other end at least partially extends out of the extension hole 13, and the rotating module 2 is used to drive the insulating rope 3 to be retracted into the main shell 1; the insulating clamp 10 is connected to one end of the insulating rope 3 extending from the extension hole 13.

[0029] In actual application, the operator only needs to pull the insulating rope 3 to a preset length, and then clamp the insulating clamp 10 at one end of the measuring line, and measure the size of the measuring line according to the length of the insulating rope 3 pulled out. In order to facilitate the operator to measure, a scale can be set on the insulating rope 3 to facilitate the operator to read the length data. When use is completed, loosen the insulating clamp 10, and the rotary module 2 drives the insulating rope 3 back into the main housing 1. Specifically, the rotary module 2 includes a rotary spring and a rotating shaft. The insulating rope 3 is wound around the rotating shaft, and the rotary spring is embedded in the center of the rotating shaft. When the insulating rope 3 is pulled out, the rotating shaft is driven to rotate, and the rotary spring accumulates elastic potential energy. When the insulating clamp 10 is loosened, the rotary spring releases the elastic potential energy, drives the rotating shaft to reverse, and the insulating rope 3 is rewound around the rotating shaft to complete the recovery of the insulating rope 3.

[0030] It should be noted that the insulating measuring rope of the present application uses a flexible insulating rope 3 as a measuring tool. The insulating rope 3 is made of a lightweight material with high insulation performance, which makes it not only safe and reliable, but also light in weight and easy to operate with one hand, greatly reducing the labor intensity of the operator; the flexible design of the insulating rope 3 enables it to fit tightly on curved or irregular drainage lines and branch lines to ensure the accuracy of the measurement results. This flexible design overcomes the defect that the traditional insulating operating rod cannot fit tightly when facing a curved line, thereby improving the accuracy and reliability of the measurement. Compared with the traditional insulating rod, the insulating rope 3 is smaller in size and lighter in weight, which greatly reduces the labor intensity of the operator and improves the efficiency and safety of the operation.

[0031] More specifically, the insulating measuring rope further includes a limiter 4 and an anti-shrinkage buckle 5, the limiter 4 is connected to one end of the insulating rope 3 extending out of the extension hole 13, the anti-shrinkage buckle 5 is arranged at the extension hole 13, and the insulating clamp 10 is arranged on a side of the limiter 4 away from the main housing 1. When the insulating rope 3 is retracted, the limiter 4 abuts against the anti-shrinkage buckle 5, limiting the insulating rope 3 from being retracted too deep into the main housing 1.

[0032] Compared with the prior art, the present application is provided with an anti-shrinkage buckle 5, which can effectively prevent the insulating rope 3 from being retracted too deeply into the main housing 1 during the recycling process, so that it can be easily pulled out when used next time; and due to the excessive elastic force of the rotary spring or the elasticity of the insulating rope 3 itself, the insulating clamp 10 may collide with the main housing 1, causing damage to the insulating clamp 10. The anti-shrinkage buckle 5 can prevent the insulating clamp 10 from colliding with the main housing 1 during the recycling process, resulting in a shortening of the service life of the equipment. The electric power measuring equipment adopting this structure solves the shortcomings of the traditional insulating operating rod in terms of weight, operating difficulty, measurement accuracy and storage convenience, and provides an efficient, accurate, lightweight and easy-to-operate measuring tool, which greatly improves the work efficiency and safety of electric power workers. By adopting this new device, the measurement of power lines will become easier and more accurate, further ensuring the stable operation of the power system.

[0033] See also Figure 1 and Figure 2 The insulating measuring rope also includes a limiting module 6 , which is movably connected to the main housing 1 , and is used to limit the insulating rope 3 from being retracted into the main housing 1 .

[0034] In actual application, when the insulating rope 3 is pulled out, the rotary module 2 accumulates elastic potential energy, and the rotary module 2 applies elastic force to the insulating rope 3, so that the insulating rope 3 retracts into the main housing 1. At this time, the operator needs to continue to pull the insulating rope 3 to prevent the insulating rope 3 from retracting. This method of measurement is extremely inconvenient. Based on this, the present application sets a limit module 6. When the operator pulls out the insulating rope 3, the limit module 6 is pushed, and the limit module 6 clamps the insulating rope 3 to limit the recovery of the insulating rope 3, ensuring the accuracy and convenience of the measurement process.

[0035] See again Figure 1 The insulating measuring rope includes a partition 7 , and a plurality of partitions 7 are arranged at intervals on the insulating rope 3 along the length direction of the insulating rope 3 .

[0036] Specifically, the partitions 7 can be evenly spaced on the insulating rope 3, for example, a partition 7 is provided every 5 cm, and accurate data reading can be ensured during the measurement process through the partitions 7. The design of the partitions 7 makes the measurement process more intuitive and simple, and even when the drainage line and the branch line are in a bent state, more accurate measurement data can be obtained by visually reading the partitions 7, reducing the measurement error caused by bending and unevenness.

[0037] See again Figure 2 Specifically, the above-mentioned limiting module 6 includes a fixed latch 61 and a movable latch 62. The fixed latch 61 is connected to the main shell 1 and is located on one side of the insulating rope 3. The movable latch 62 is slidably connected to the main shell 1 and is located on the other side of the insulating rope 3. The movable latch 62 can slide toward the direction close to the fixed latch 61 to clamp the insulating rope 3.

[0038] In actual application, the fixed latch 61 is fixed in the main shell 1, and the movable latch 62 can slide relative to the main shell 1 to move toward or away from the fixed latch 61. The insulating rope 3 passes between the fixed latch 61 and the movable latch 62. When the operator pulls the insulating rope 3 to a preset length, the operator pushes the movable latch 62, and the movable latch 62 moves toward the fixed latch 61, clamping the insulating rope 3 between the movable latch 62 and the fixed latch 61. The clamping force of the movable latch 62 and the fixed latch 61 can prevent the insulating rope 3 from being pulled back by the rotary module 2, thereby ensuring the normal progress of the measurement work.

[0039] See also Figure 3 The movable latch 62 includes a movable portion 621 and a buckle portion 622. The side of the main shell 1 on which the extension hole 13 is provided is set as the outer portion 11. The outer portion 11 is provided with a buckle groove 14 connected to the installation space 12. The buckle portion 622 is slidably connected to the buckle groove 14. The movable portion 621 is connected to the side of the buckle portion 622 facing the installation space 12. The movable portion 621 is used to clamp the insulating rope 3.

[0040] In order to facilitate the operator to push the movable latch 62, the movable latch 62 includes a buckle portion 622 and a movable portion 621. The buckle portion 622 is slidably connected in the buckle groove 14 and protrudes from the outer surface of the main shell 1. In this way, when the insulating rope 3 needs to be fixed, the operator only needs to push the buckle portion 622 to slide in the buckle groove 14 to drive the movable portion 621 to move, thereby realizing the function of the movable portion 621 and the fixed latch 61 clamping the insulating rope 3.

[0041] See also Figure 4 and Figure 5The limiting module 6 also includes a baffle 63, which is connected to the main shell 1 and is located on the side of the movable part 621 away from the buckle part 622. A slide groove 15 is defined between the baffle 63 and the outer part 11, and the movable part 621 is at least partially slidably set in the slide groove 15; the movable part 621 includes a straight portion 6212 and a curved portion 6211 connected to each other, the straight portion 6212 is at least partially located in the slide groove 15, and the curved portion 6211 is connected to the side of the straight portion 6212 away from the slide groove 15, and the curved portion 6211 is used to abut against the baffle 63 to limit the sliding of the movable part 621.

[0042] In actual application, the movable portion 621 is at least partially arranged between the baffle 63 and the outer portion 11, and the interval between the baffle 63 and the outer portion 11 forms a slide groove 15, and the movable portion 621 is at least partially located in the slide groove 15. Specifically, the movable portion 621 includes a straight portion 6212 and a curved portion 6211, the straight portion 6212 is at least partially located in the slide groove 15, and is slidably connected to the slide groove 15, and the curved portion 6211 is connected to the side of the straight portion 6212 away from the slide groove 15, and the curved portion 6211 is in contact with the inner side surface of the main shell 1. When the operator pushes the buckle portion 622 to slide in the buckle groove 14, the buckle portion 622 drives the movable portion 621 to move, and the straight portion 6212 slides in the slide groove 15 until the straight portion 6212 abuts against the insulating rope 3, and the straight portion 6212 and the fixed clamping teeth 61 clamp the insulating rope 3, at this time, the curved portion 6211 also just abuts against the baffle 63. Since the extension direction of the curved portion 6211 is a curve, the curved portion 6211 forms an angle with the extension direction of the slide 15, so the curved portion 6211 cannot enter the slide 15, thereby limiting the continued movement of the movable portion 621, preventing the operator from pushing the buckle portion 622 too hard, increasing the clamping force of the movable portion 621 on the insulating rope 3, and preventing the movable portion 621 from damaging the insulating rope 3, affecting the measurement accuracy of the insulating rope 3. At the same time, the abutting force between the curved portion 6211 and the baffle 63 can also prevent the buckle portion 622 from sliding under external force, play a certain degree of fixing role, and ensure the stability of the limiting module 6 clamping the insulating rope 3.

[0043] See again Figure 4 , along the sliding direction of the buckle portion 622, the extension length of the curved portion 6211 is greater than the extension length of the buckle slot 14. This arrangement can ensure that during the sliding process of the buckle portion 622, the curved portion 6211 can always cover the buckle slot 14, preventing external impurities from entering the main housing 1 through the buckle slot 14.

[0044] See again Figure 5 The anti-shrinkage buckle 5 includes a main body 51 and an adsorption portion 52. The main body 51 is provided with a through hole 53, and the insulating rope 3 extends from the through hole 53. The adsorption portion 52 is connected to a side of the main body 51 close to the limiting portion 4, and the adsorption portion 52 is used to adsorb the limiting portion 4.

[0045] In actual applications, the equipment usually needs to be transported to a designated construction location. In order to prevent the insulating rope 3 from falling out of the main housing 1 during transportation, the present application sets an adsorption portion 52 on the anti-shrinkage buckle 5. When not in use, a certain adsorption force is formed between the adsorption portion 52 and the limiting portion 4, which can prevent the limiting portion 4 from falling out under its own weight or during transportation, thereby causing the insulating rope 3 to extend, causing the insulating rope 3 to be entangled with other equipment, increasing the difficulty for operators to separate and transport the equipment. At the same time, the perforation 53 can be chamfered to prevent sharp edges from scratching the insulating rope 3.

[0046] It is understandable that the adsorption portion 52 and the limiting portion 4 can be made of magnetic materials, and the two are adsorbed together by generating a magnetic attraction force.

[0047] See again Figure 5 The insulating measuring rope includes a plurality of rollers 8 , which are connected to the main housing 1 and symmetrically arranged on both sides of the insulating rope 3 , and are used to guide and support the insulating rope 3 .

[0048] Specifically, the roller 8 can be arranged between the anti-shrinkage buckle 5 and the limit module 6. The present application can set two rollers 8, and the two rollers 8 are relatively arranged on both sides of the insulating rope 3. The insulating rope 3 passes between the two rollers 8 and then passes through the through hole 53. The two rollers 8 clamp the insulating rope 3 to play a supporting role, prevent the insulating rope 3 from falling, and reduce the probability of the insulating rope 3 being stuck, which is conducive to the operator to pull out the insulating rope 3 smoothly. At the same time, the rotation of the roller 8 can assist in pulling out the insulating rope 3, saving the operator's physical strength.

[0049] It should be noted that, in order to improve the durability of the equipment, the main housing 1, the limit module 6 and the insulating rope 3 are all made of high-strength wear-resistant materials and can be used for a long time in a harsh working environment without being damaged.

[0050] Different from the prior art, the embodiment of the present application provides an electric power measuring device and an insulating measuring rope thereof, wherein the insulating measuring rope comprises a main housing 1, a rotary module 2, a limiting portion 4, an anti-shrinkage buckle 5 and an insulating rope 3. An installation space 12 is provided inside the main housing 1, and an extension hole 13 communicating with the installation space 12 is provided outside the main housing 1; the rotary module 2 is installed in the installation space 12; one end of the insulating rope 3 is wound around the rotary module 2, and the other end at least partially extends out of the extension hole 13, and the rotary module 2 is used to drive the insulating rope 3 to be retracted into the main housing 1; and an insulating clamp 10 is connected to one end of the insulating rope 3 extending from the extension hole 13. The limiting portion 4 is connected to one end of the insulating rope 3 extending out of the extension hole 13, the anti-shrinkage buckle 5 is arranged at the extension hole 13, and the insulating clamp 10 is arranged on the side of the limiting portion 4 away from the main housing 1. When the insulating rope 3 is retracted, the limiting portion 4 abuts against the anti-shrinkage buckle 5 to limit the insulating rope 3 from being retracted too deep into the main housing 1. Compared with the prior art, the present application is provided with an anti-shrinkage buckle 5, which can effectively prevent the insulating rope 3 from being retracted too deeply into the main housing 1 during the recycling process, so that it can be easily pulled out when used next time; and due to the excessive elastic force of the rotary spring or the elasticity of the insulating rope 3 itself, the insulating clamp 10 may collide with the main housing 1, causing damage to the insulating clamp 10. The anti-shrinkage buckle 5 can prevent the insulating clamp 10 from colliding with the main housing 1 during the recycling process, resulting in a shortening of the service life of the equipment. The electric power measuring equipment adopting this structure solves the shortcomings of the traditional insulating operating rod in terms of weight, operating difficulty, measurement accuracy and storage convenience, and provides an efficient, accurate, lightweight and easy-to-operate measuring tool, which greatly improves the work efficiency and safety of electric power workers. By adopting this new device, the measurement of power lines will become easier and more accurate, further ensuring the stable operation of the power system.

[0051] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
