Description

Technical Field

[0001] This utility model belongs to the field of power engineering measurement technology, and specifically relates to a power engineering measurement device. Background Technology

[0002] Electrical engineering mainly studies the generation, transmission, distribution, and use of electrical energy, including power plants, transmission lines, substations, and distribution systems. It may also involve the design, operation, and maintenance of power equipment, as well as the stability and efficiency of power systems. Electrical engineering generally requires the use of cables, and workers need to measure the length of cables required for certain equipment. Therefore, special measuring devices are used. However, some existing measuring devices often have certain shortcomings in use, so they need to be improved.

[0003] Chinese patent CN221744886U discloses a power engineering measuring device, including a connecting plate. A housing is fixedly connected to the upper surface of the connecting plate. A rolling bearing is fixedly embedded in the inner bottom wall of the housing, and a sealed bearing is fixedly embedded in the upper surface of the housing. A sliding opening is provided on the front of the housing. This device is equipped with a crank, a threaded rod, a threaded cylinder, a movable plate, rolling bearings, sealed bearings, a meter counter, a controller, a display, and a pressure roller. The crank and threaded rod work together to facilitate the threaded cylinder to drive the movable plate up and down. At this time, the movement of the movable plate and sliding rod makes it easier for the pressure roller to approach the meter counter and to apply pressure to the cable. Then, the movement of the cable facilitates the rotation of the meter counter and the pressure roller. Simultaneously, the coordination of the meter counter, controller, and display makes it easy for operators to understand the length of the cable. The measurement method is simple to operate, convenient to use, fast, and highly accurate.

[0004] However, although the above technical solution can achieve the purpose of measuring cable length, in actual use, especially after the cable passes between the pressure roller and the wheel on the meter counter, the length of the cable will be calculated, but the pressure roller and the wheel on the meter counter will rotate a certain number of times due to inertia. This will cause the value on the meter counter to change, resulting in the inaccurate value of the cable measurement. Therefore, it has certain limitations in use. Utility Model Content

[0005] The purpose of this utility model is to provide a power engineering measurement device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power engineering measuring device includes: a counterweight base, a housing fixedly connected to the top of the counterweight base, a fixed plate fixedly connected to one side of the top of the housing, a positioning plate fixedly connected to the other side of the top of the housing, a meter counter fixedly connected to the top of one side of the positioning plate, a guide roller rotatably arranged inside the meter counter, a hydraulic cylinder fixedly connected inside the fixed plate, a push rod fixedly connected to the output end of the hydraulic cylinder, an arc-shaped anti-slip block fixedly connected to the bottom end of the push rod, two vertical plates penetrating inside the fixed plate, a pressing wheel rotatably arranged at the bottom end of the inner sidewall of the vertical plate, a support block fixedly connected to the top of one side of the inner sidewall of the fixed plate, a touch switch arranged on the top of the support block, a pressing rod fixedly connected to the top of one side of the vertical plate, and a display fixedly connected to the other side of the top of the housing, and the display is electrically connected to the meter counter.

[0011] Preferably, a compression block is fixedly connected to the top of the surface of the vertical plate, and the bottom end of the second compression spring is fixedly connected to the top of the compression block.

[0012] Preferably, a control panel is fixedly connected to the top of one side of the box surface, and the control panel is electrically connected to the meter counter and the hydraulic cylinder respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When measuring the power engineering equipment, the staff can measure the length of the cable in a timely manner. After the cable length is measured, the arc-shaped anti-slip block can be used to resist it in a timely manner to prevent the meter counter from rotating due to its own rotation, which would result in inaccurate cable length measurement. At the same time, the operation is simple and convenient for staff to use.

[0015] (2) The overall device is easy for staff to move to the appropriate position. The counterweight base can keep the box stable. When used outdoors, the plug rod can be inserted into the ground to keep it stable. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figures 1 to 3As shown, a power engineering measuring device includes a counterweight base 1, a housing 2 fixedly connected to the top of the counterweight base 1, a fixing plate 3 fixedly connected to one side of the top of the housing 2, a positioning plate 4 fixedly connected to the other side of the top of the housing 2, a meter counter 5 fixedly connected to the top of one side of the positioning plate 4, a guide roller 6 rotatably arranged inside the meter counter 5, a hydraulic cylinder 7 fixedly connected inside the fixing plate 3, a push rod 8 fixedly connected to the output end of the hydraulic cylinder 7, an arc-shaped anti-slip block 9 fixedly connected to the bottom end of the push rod 8, two vertical plates 10 penetrating inside the fixing plate 3, a pressing wheel 11 rotatably arranged at the bottom end of the inner side wall of the vertical plate 10, a support block fixedly connected to the top of one side of the inner side wall of the fixing plate 3, a touch switch 12 arranged on the top of the support block, a pressing rod 13 fixedly connected to the top of one side of the vertical plate 10, and a display 17 fixedly connected to the other side of the top of the housing 2, and the display 17 is electrically connected to the meter counter 5. The housing 2 provides support for the entire device. The fixing plate 3 secures the hydraulic cylinder 7 inside, providing driving force for the push rod 8. This causes the push rod 8 to move the arc-shaped anti-slip block 9 left and right, limiting the guide roller 6. The pressing wheel 11 allows the cable to rotate when pulled between the guide roller 6 and the pressing wheel 11, thus enabling the meter counter 5 to count. The pressing rod 13 presses the touch switch 12, which is electrically connected to the hydraulic cylinder 7. The display 17 is electrically connected to the meter counter 5 to display the cable length parameter.

[0023] A placement cavity 14 is fixedly connected to the inner top wall of the fixing plate 3, and a second compression spring 16 is fixedly connected to the inner top wall of the placement cavity 14. The placement cavity 14 is used to fix the second compression spring 16.

[0024] A compression block 15 is fixedly connected to the top of the surface of the vertical plate 10, and the bottom end of the second compression spring 16 is fixedly connected to the top of the compression block 15. By setting the second compression spring 16 and the compression block 15, the vertical plate 10 can be adjusted upward by a certain distance, so that the second compression spring 16 is compressed until it is compressed.

[0025] A control panel is fixedly connected to the top of one side of the surface of the housing 2, and the control panel is electrically connected to the meter counter 5 and the hydraulic cylinder 7 respectively.

[0026] Example 2:

[0027] Please see Figure 1As shown, two strip plates 18 are fixedly connected to the bottom of both sides of the box 2. Insertion rods 19 are threaded into the interior of the strip plates 18, and a turntable 20 is fixedly connected to the top of the insertion rods 19. The strip plates 18 allow the insertion rods 19 to be threaded through them, enabling them to be inserted into the ground and keeping the box 2 fixed. The turntable 20 makes it easier for workers to rotate the insertion rods 19. The top of the insertion rod 19 is threaded, while the bottom is smooth.

[0028] A first compression spring 21 is fixedly connected to the top of the strip plate 18, and the top of the first compression spring 21 is rotatably connected to the bottom of the turntable 20. A handle 22 is rotatably provided inside the box body 2. The first compression spring 21 provides a certain upward resistance force after the plug rod 19 is rotated, making it easy for the operator to remove the plug rod 19. The handle 22 makes it easy for the operator to move the box body 2.

[0029] The working principle of this utility model is as follows: The operator moves the housing 2 to a suitable position using the handle 22, then rotates the plug-in rod 19 using the turntable 20, causing the plug-in rod 19 to insert into the ground, thus fixing the housing 2. The operator then places the cable to be measured between the guide roller 6 and the pressing wheel 11. Simultaneously, the operator lifts the vertical plate 10 upwards. The pressing block 15 at the top of the vertical plate 10 then compresses the second compression spring 16, causing it to move upwards along with the pressing wheel 11 and the pressing rod 13. At this point, the operator places the cable between the pressing wheel 11 and the guide roller 6. The operator then stops lifting the vertical plate 10, and the second compression spring 16 returns to its original position, causing the pressing wheel 11 to contact the ground. The cable is then pulled along the surface of the guide roller 6 and the pressing wheel 11, causing them to rotate continuously. The meter counter 5 continuously records the values, and the displayed value signal is transmitted to the control panel. The control panel displays the value on the display 17. After the cable length measurement is completed, the cable is detached from the guide roller 6 and the pressing wheel 11. Then, the vertical plate 10 drives the pressing wheel 11 to descend, which in turn causes the pressing rod 13 to descend. The pressing rod 13 presses the touch switch 12, and the touch switch 12 transmits a signal to the control panel. The control panel then controls the hydraulic cylinder 7 to work. The output end of the hydraulic cylinder 7 drives the push rod 8 to move to the left until the arc-shaped anti-slip block 9 touches the surface of the guide roller 6 to prevent it from rotating and to ensure the accuracy of the meter counter 5.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
