Technical Field

[0001] The present invention relates to the technical field of insulation resistance meters, and particularly to an insulation resistance meter for power detection. Background Technique

[0002] The insulation resistance meter for power detection is a test instrument with innovative design and advanced functions. It integrates intelligent technology and remote control capabilities, providing a more efficient, accurate and convenient solution for electrical insulation testing, and has the following functions: It has an automatic range switching function, which can automatically select an appropriate measurement range according to the resistance value of the object to be measured to ensure the accuracy of the measurement result; it can automatically record and store measurement data for subsequent analysis and processing; it adopts advanced measurement technology to provide high-precision insulation resistance measurement results to meet various strict test requirements; it is equipped with a clear and easy-to-understand display screen to display measurement data and test status in real time, facilitating operators to quickly obtain information; it uses high-quality materials and advanced manufacturing processes, has good anti-interference ability and durability, and can operate stably in harsh working environments. The insulation resistance meter for power detection has a very wide range of application fields. It is used for the insulation resistance test of substation equipment, transmission lines, etc. to ensure the safe operation of the power system. It is suitable for the regular maintenance and fault troubleshooting of electrical equipment such as motors, transformers, and switch cabinets in factories. During the electrical installation and acceptance process of buildings, it detects the insulation status of lines and equipment.

[0003] Existing insulation resistance meters for power detection all need to be placed horizontally on a plane for use and measurement. However, most resistance meters do not have a mechanism for automatically adjusting their horizontal state, which leads to a reduction in measurement efficiency or further affects the measurement stability. Secondly, the lack of an automatic horizontal adjustment mechanism will further affect the measurement stability. The measurement result of the insulation resistance meter has a high requirement for the horizontal state. Because if the resistance meter is not in a horizontal state, the internal precision measurement components will be affected by uneven gravity. And during use, if the insulation performance of the equipment is poor and the insulation performance of the equipment cannot meet the requirements, there is a high possibility of leakage, which will cause great damage to the insulation resistance meter for power detection.

[0026] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0027] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Example 1: Refer to Figures 1 - 3 , the present invention provides a technical solution: an insulation resistance meter for power detection, including a resistance meter main body 1. A rectangular card slot 4 is clamped on the lower surface of the resistance meter main body 1. A flexible bellows 5 is fixedly connected to the outer surface of the rectangular card slot 4. A base box body 2 is fixedly connected to the outer surface of the flexible bellows 5. A horizontal bubble tube 7 and a vertical bubble tube 8 are fixedly connected to the top of the resistance meter main body 1. A balance adjustment mechanism 3 and an overrun adjustment mechanism 6 are fixedly connected to the inside of the base box body 2. An insulation protection mechanism 9 is clamped inside the base box body 2.

[0029] The balance adjustment mechanism 3 includes a first spherical groove 301. The top of the first spherical groove 301 is fixedly connected to the rectangular card slot 4. A first ball head hinge 302 is rotatably connected to the inside of the first spherical groove 301. A first hydraulic pump 303 is fixedly connected to the bottom of the first ball head hinge 302. A second ball head hinge 304 is fixedly connected to the bottom of the first hydraulic pump 303. The outer surface of the second ball head hinge 304 is rotatably connected to a second spherical groove 305. A first circular column 306 is fixedly connected to the bottom of the second spherical groove 305. A straight groove 307 is provided inside the first circular column 306. A second circular column 308 is rotatably connected to the inner wall of the straight groove 307. A first connecting block 311 is rotatably connected to the outer surface of the second circular column 308. A cushion block 312 is fixedly connected to the bottom of the first connecting block 311. A third circular column 313 is fixedly connected to the bottom of the cushion block 312. A first spring 309 is fixedly connected to the lower surface of the second spherical groove 305. A clamping piece 310 is fixedly connected to the bottom of the first spring 309. The clamping piece 310 is in contact with the outer surface of the first connecting block 311; Four groups of the balance adjustment mechanism 3 are fixedly connected to the lower surface of the rectangular card slot 4. And each group of the cushion blocks 312 and the third circular columns 313 are clamped with the base box body 2 through card slots. The top of the second spherical groove 305 is provided with a rounded arc surface, and the rounded arc surface is larger than the card slot for clamping the cushion block 312. And two first connecting blocks 311 are symmetrically arranged and are both fixedly connected to the cushion block 312. By setting the balance adjustment mechanism 3, through the first hydraulic pump 303, the first spherical groove 301, the first ball head hinge 302, the second spherical groove 305, and the second ball head hinge 304, the horizontal and vertical angles of the resistance meter main body 1 placed on an inclined surface can be adjusted, so that the resistance meter main body 1 remains horizontal in both the horizontal area and the vertical area. And the adjustment speed can be slowed down by the first hydraulic pump 303 when adjusting the horizontal angle and the vertical angle, reducing the effect that the precision measurement elements inside the resistance meter main body 1 will be unevenly affected by gravity because the resistance meter main body 1 is not in a horizontal state.

[0030] The working principle of this embodiment is as follows: When using this insulation resistance meter for power detection, when on an inclined surface, the first hydraulic pump 303 pushes the second ball head hinge 304 and the second spherical groove 305 downward, driving the first circular column 306 downward. The first circular column 306 slides in the straight notch 307 through the first spring 309 and the clip 310, pushing the symmetrically arranged first connecting block 311 downward. At this time, due to the first latch 610, the hole on the inner bottom of the base box body 2 and the hole of the cushion block 312 for clamping, the movement of the first connecting block 311 stops and reversely pushes the bottom of the first hydraulic pump 303, simultaneously driving the first ball head hinge 302 and the first spherical groove 301 upward, thereby pushing the inclination of the rectangular card slot 4 to adapt to the angle of the inclined surface. The horizontal adjustment is achieved by observing the horizontal bubble tube 7 and the vertical bubble tube 8.

[0031] Embodiment 2: Please refer to Figures 4 - 6 , on the basis of Embodiment 1, the present invention provides a technical solution: The overrun adjusting mechanism 6 includes a third spherical groove 601, a third ball head hinge 602 is rotatably connected inside the third spherical groove 601, a first rectangular column 603 is fixedly connected to the bottom of the third ball head hinge 602. The first rectangular column 603 is rotatably connected to a first rotating shaft 604 through a through hole. A first rotating rod 605 is rotatably connected to the outer surface of the first rotating shaft 604. The right side of the first rotating rod 605 is rotatably connected to a second rotating shaft 606 through a through hole. A second rotating rod 607 is rotatably connected to the outer surface of the second rotating shaft 606. The bottom of the second rotating rod 607 is rotatably connected to a third rotating shaft 608 through a through hole. An arc-shaped push rod 609 is rotatably connected to the outer surface of the third rotating shaft 608. A first latch 610 is fixedly connected to the right side of the arc-shaped push rod 609. A first card slot 611 is opened at the inner bottom of the base box body 2. The first latch 610 is clamped with the first card slot 611. A second rectangular column 612 and a third rectangular column 613 are fixedly connected to the inner bottom of the base box body 2. The outer surface of the middle part of the second rectangular column 612 is rotatably connected to a fourth rotating shaft 614 through a through hole. The outer surface of the fourth rotating shaft 614 is rotatably connected to the second rotating rod 607 and the third rectangular column 613. The top of the outer surface of the second rectangular column 612 is rotatably connected to a fifth rotating shaft 615 and the third rectangular column 613 through a through hole; The lower surface of the right end of the first clamping block 610 is in contact with the top of the cushion block 312, and the upper surface of the right end of the first clamping block 610 is in contact with the lower surface of the first circular column 306. The width of the first clamping block 610 is the same as the spacing between the symmetrically arranged first connecting blocks 311. There are four groups of the overrunning adjustment mechanism 6 fixedly connected to the lower surface of the rectangular card slot 4, and a second card slot 901 is formed on the upper surface of the arc surface push rod 609 of each group. By setting the overrunning adjustment mechanism 6, when the angle of the inclined surface is too large, resulting in insufficient angle performance or limited adjustment angle of the balance adjustment mechanism 3, the overrunning adjustment of the balance adjustment mechanism 3 can be realized through the cooperation of the first clamping block 610 and the balance adjustment mechanism 3, so that the main body 1 of the resistance meter is in a relatively stable adjustment plane, and the function of adjusting a large-angle inclined surface with a small angle can be realized, and the effect of the uneven influence of gravity on the precision measurement elements inside it is reduced.

[0032] The working principle of this embodiment is as follows: When using the insulating resistance meter for power detection, when on a large inclined surface, when the balance adjustment mechanism 3 cannot completely eliminate the inclination angle, the larger inclined surface drives the third spherical groove 601 and the third ball head hinge 602 to move upward, driving the first rectangular column 603 to move upward, and driving the first rotating shaft 604 to move upward. At this time, due to the second rectangular column 612, the third rectangular column 613 and the fifth rotating shaft 615, the first rotating rod 605 rotates around the fifth rotating shaft 615. The first rotating rod 605 causes the second rotating rod 607 to rotate through the second rotating shaft 606, the second rectangular column 612, the third rectangular column 9613 and the fourth rotating shaft 614, and through the third rotating shaft 608, the arc surface push rod 609 converts the rotation into a leftward movement, and moves leftward along the first card slot 611 through the first clamping block 610, gradually moving out of the upper surface of the cushion block 312, so that the first spring 309 and the clamping piece 310 push the symmetrically arranged first connecting blocks 311 to move downward, driving the cushion block 312 and the third circular column 313 to move downward, gradually moving out of the through hole at the inner bottom of the base box body 2, and contacting the inclined surface, and realizing the rotation of the first connecting block 311, the cushion block 312 and the third circular column 313 through the second circular column 308 to adapt to the inclined surface. At this time, the horizontal adjustment is realized by observing the horizontal bubble tube 7 and the vertical bubble tube 8.

[0033] Embodiment Three: Please refer to Figures 7 - 9, on the basis of the first embodiment, the present invention provides a technical solution: The insulation protection mechanism 9 includes a second card slot 901. The upper surface of the arc-shaped push rod 609 is provided with the second card slot 901. A second card block 902 is clamped inside the second card slot 901. The right end of the second card block 902 is slidably connected to a fourth circular column 903 through a through hole. The top of the fourth circular column 903 is fixedly connected to a second connection block 905. The right side of the second connection block 905 is fixedly connected to a first rectangular push rod 906 and a second rectangular push rod 907. The right end of the second card block 902 is fixedly connected to a second spring 904. The right ends of the first rectangular push rod 906 and the second rectangular push rod 907 are fixedly connected to a fourth rectangular column 908. The top of the fourth rectangular column 908 is fixedly connected to a third connection block 909. The middle axis of the base box body 2 is clamped with a circular card block 910 through a card slot. The bottom of the circular card block 910 is fixedly connected to an elastic bump 911. The inner bottom of the base box body 2 is fixedly connected to a card sleeve 916. The inner surface of the card sleeve 916 is fixedly connected to a motor 914. The output end of the motor 914 is fixedly connected to a cam 915. The top of the motor 914 is fixedly connected to a warning device 913. The inner bottom of the base box body 2 is fixedly connected to a signal processing device 912; The output end of the motor 914 is in contact with the upper surface of the circular card block 910. The lower surface of the cam 915 is in contact with the upper surface of the fourth rectangular column 908. The length of the card sleeve 916 is the same as that of the motor 914 and does not interfere with the rotation of the cam 915. By setting the insulation protection mechanism 9, during the use of the resistance meter main body 1, through the motor 914, the signal processing device 912, the warning device 913 and the cam 915, it is possible to avoid the occurrence of electric leakage when the insulation performance of the equipment is poor and the insulation performance of the equipment fails to meet the requirements, and to protect the internal precision measurement components from being damaged by the effect of damaging the insulation resistance meter for power detection.

[0034] The working principle of this embodiment is as follows: When using this insulation resistance meter for power detection, when it is on an inclined surface and the insulation performance of the device is poor and cannot meet the requirements, in case of electric leakage, the elastic bump 911 is pressed down to contact the leakage surface, and the signal is transmitted to the signal processing device 912 through the circular clamping block 910. The signal processing device 912 transmits the signal to the warning device 913. The warning device 913 starts the motor 914, and the rotation of the motor 914 drives the cam 915 fixedly connected to the output end of the motor 914 to rotate, causing the first rectangular push rod 906 and the second rectangular push rod 907 to move along the rectangular card slot 4 at the inner bottom of the base box body 2, and driving the second connecting block 905 to move. The second connecting block 905 pushes the first clamping block 610 to move outward through the fourth circular column 903, the second clamping block 902 and the second card slot 901, so that the first clamping block 610 moves out of the upper surface of the cushion block 312. At this time, the working principle process of the second embodiment is repeated, so that the symmetrically arranged cushion blocks 312 and the third circular columns 313 both move out of the lower surface of the base box body 2, causing the overall rise of the rectangular card slot 4 and driving the main body 1 of the resistance meter to rise, so that it leaves the leaking inclined surface, realizing insulation protection. And when the second card slot 901 on the arc-shaped push rod 609 does not have electric leakage and the working principle of the second embodiment is carried out, the second clamping block 902 jumps upward from the second card slot 901, so that the arc-shaped push rod 609 moves outward without driving the second clamping block 902 to move, reducing the weight, realizing large-angle adjustment, and the second spring 904, the fourth circular column 903 and the through hole at the right end of the second clamping block 902 cooperate to absorb the jump.
