Description

Technical Field

[0001] The utility model relates to the technical field of insulator tester supports, in particular to a special insulating operating rod for installing an insulator string voltage measuring device. Background Art

[0002] The insulator strings used for laying high-voltage lines need to be regularly tested for voltage after being put into use in order to determine whether the insulators can continue to be used and to avoid affecting the safety of the line due to insulator deterioration.

[0003] At present, the instrument used for measuring the insulator voltage is an insulator tester, which has many types. For example, it may include a receiver and a transmitter. A capacitive voltage sensor, a converter, an amplifier, a single-chip microcomputer, a wireless transmission circuit and a power module are arranged in the transmitter. After the capacitive voltage sensor divides the voltage signal, it is converted by the converter and amplified by the amplifier, and then converted into a digital signal, and the digital signal is sent to the receiver through the wireless transmission circuit. A power module, a touch screen, a wireless receiving circuit and a single-chip microcomputer are arranged in the receiver. After the wireless receiving circuit receives the signal, it processes, displays and stores it. It can also be set as an insulator tester disclosed in a Chinese patent with a patent publication number of CN204154787U. Regardless of the type of insulator tester, it includes a capacitive voltage sensor, a probe and a digital display. When using an insulator tester to detect the voltage of an insulator, since the insulator string is set at the edge of the tower, in order to ensure the safety of the workers, when the workers climb to the tower, they need to support the insulator tester with a support rod and move the insulator tester to the insulator so that the probe is connected to the end of the insulator, such as a Chinese patent disclosed in Patent Publication No. CN204154787U.

[0004] When using a support rod to support the insulator tester to be stably placed on the side of the insulator, the staff's hands need to hold the end of the support rod. At this time, the arm is in an inclined state and in a high-strength state to ensure that the insulator tester is stably placed. Because the insulator string contains multiple insulators distributed up and down, the staff needs to hold the support rod to complete the detection of multiple insulators. This work intensity will cause the staff to be tired and arm pain. In addition, the existing connection method between the support rod and the insulator tester is single, and the support rod and the insulator tester are located on the same straight line. It is inconvenient to adjust the relative position of the support rod and the insulator tester according to the actual needs of insulator detection. For example, when the insulator tester and the support rod are located on the same straight line, the staff can control the support rod to be relatively horizontal. If the staff is located on the side of the insulator string, the insulator tester can be controlled to be placed near the insulator. If the staff is located above the insulator string, it is impossible to control the probe of the insulator tester to contact the two ends of the insulator, which is not conducive to the staff to easily and better complete the detection task.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments: Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a special insulating operating rod for installing an insulator string voltage measuring device comprises a bottom rod 1, an intermediate rod 2 and a top rod 3 made of insulating material. The bottom rod 1 and the top rod 3 are each provided with one, and the intermediate rod 2 can be provided with multiple ones. The bottom rod 1, the intermediate rod 2 and the top rod 3 are connected end to end. Specifically, a first thread groove 11 is provided on the top of the bottom rod 1, a second thread groove 22 is provided on the top of the intermediate rod 2, a first thread column 21 is provided on the bottom of the intermediate rod 2, and a second thread column 31 is provided on the bottom of the top rod 3. When the bottom rod 1, the intermediate rod 2 and the top rod 3 are spliced, the first thread column 21 is inserted into the first thread groove 11, or inserted into the second thread groove 22 of another intermediate rod 2, and the second thread column 31 is inserted into the second thread groove 22. In this way, not only the length of the operating rod can be adjusted according to needs, but also the disassembly of the operation can be realized, which provides convenience for the staff to lift the operating rod to the top of the tower and is convenient for the staff to carry the device. In addition, the operating rod composed of the bottom rod 1, the middle rod 2 and the top rod 3 is thick at the bottom and thin at the top, which reduces the strength of the staff to hold the operating rod.

[0028] like Figure 2As shown, in order to further reduce the labor intensity of the staff, a support arc plate 14 and a bracket 12 are hingedly arranged at the bottom of the bottom rod 1, and the support arc plate 14 includes a rigid arc plate and two connecting belts, the two connecting belts are respectively arranged at the two ends of the rigid arc plate, and the ends adjacent to each other are connected by a Japanese buckle, the rigid arc plate is arranged on the front side of the staff's waist, the two connecting belts are connected and wrapped around the staff's waist, and a drawstring 13 is arranged on the side of the bracket 12. Therefore, when the staff installs the insulator tester 5 on the top of the operating rod, the insulator tester 5 is a prior art, which includes a capacitive voltage sensor, a probe, a digital display, etc., when the capacitor After the voltage sensor divides the voltage signal, it is converted by the converter and amplified by the amplifier to be converted into a digital signal, and the digital signal is sent to the digital display through the wireless transmission circuit. Since the insulator tester 5 is a prior art, it will not be described in detail here. Then the rigid arc plate is worn on the waist of the staff through the connecting belt, and the operating rod is supported by the rigid arc plate to reduce the strength of the staff's arm. In addition, the palm of the staff can pull the drawstring 13, and the operating rod is controlled by the drawstring 13 to be in a relatively stable horizontal state. Even if the operating rod, the drawstring 13 and the staff form a triangular structure, the pain caused by holding the operating rod in the arm of the I-shaped staff is effectively alleviated. When the staff pulls the drawstring 13, one palm can complete it, and the other palm can operate other equipment or hold other equipment. Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a special insulating operating rod for installing an insulator string voltage measuring device comprises a bottom rod 1, an intermediate rod 2 and a top rod 3 made of insulating material. The bottom rod 1 and the top rod 3 are each provided with one, and the intermediate rod 2 can be provided with multiple ones. The bottom rod 1, the intermediate rod 2 and the top rod 3 are connected end to end. Specifically, a first thread groove 11 is provided on the top of the bottom rod 1, a second thread groove 22 is provided on the top of the intermediate rod 2, a first thread column 21 is provided on the bottom of the intermediate rod 2, and a second thread column 31 is provided on the bottom of the top rod 3.

In this way, not only the length of the operating rod can be adjusted according to needs, but also the disassembly of the operation can be realized, which provides convenience for the staff to lift the operating rod to the top of the tower and is convenient for the staff to carry the device. In addition, the operating rod composed of the bottom rod 1, the middle rod 2 and the top rod 3 is thick at the bottom and thin at the top, which reduces the strength of the staff to hold the operating rod.

[0030] like Figure 2As shown, in order to further reduce the labor intensity of the staff, a support arc plate 14 and a bracket 12 are hingedly arranged at the bottom of the bottom rod 1, and the support arc plate 14 includes a rigid arc plate and two connecting belts, the two connecting belts are respectively arranged at the two ends of the rigid arc plate, and the ends adjacent to each other are connected by a Japanese buckle, the rigid arc plate is arranged on the front side of the staff's waist, the two connecting belts are connected and wrapped around the staff's waist, and a drawstring 13 is arranged on the side of the bracket 12. Therefore, when the staff installs the insulator tester 5 on the top of the operating rod, the insulator tester 5 is a prior art, which includes a capacitive voltage sensor, a probe, a digital display, etc., when the capacitor After the voltage sensor divides the voltage signal, it is converted by the converter and amplified by the amplifier to be converted into a digital signal, and the digital signal is sent to the digital display through the wireless transmission circuit. Since the insulator tester 5 is a prior art, it will not be described in detail here. Then the rigid arc plate is worn on the waist of the staff through the connecting belt, and the operating rod is supported by the rigid arc plate to reduce the strength of the staff's arm. In addition, the palm of the staff can pull the drawstring 13, and the operating rod is controlled by the drawstring 13 to be in a relatively stable horizontal state. Even if the operating rod, the drawstring 13 and the staff form a triangular structure, the pain caused by holding the operating rod in the arm of the I-shaped staff is effectively alleviated. When the staff pulls the drawstring 13, one palm can complete it, and the other palm can operate other equipment or hold other equipment.

[0031] like Figure 4 , Figure 5 As shown, in order to realize the adjustable connection between the insulator tester 5 and the operating rod, a connecting mechanism 4 is arranged at the top of the mandrel 3, and the connecting mechanism 4 includes a sleeve 41 and a support plate 42. The support plate 42 is arranged as a right-angle structure and is arranged on the side of the sleeve 41. At the same time, the bolt threadedly arranged through the support plate 42 is inserted into the fourth thread groove 44 at the top of the sleeve 41. The sleeve 41 is sleeved on the top of the mandrel 3, and the outer wall of the sleeve 41 is arranged as a frustum structure, which is sleeved on the mandrel 3 by bolts. A third thread groove 32 is also arranged on the mandrel 3, and the bolt threadedly arranged through the support plate 42 can be inserted into the third thread groove 32. This arrangement can make the support plate 42 stably installed on the mandrel 3.

[0032] like Figure 5 , Figure 6 , Figure 7As shown, in addition, buckle grooves 43 are provided on two mutually perpendicular side walls of the support plate 42, and the central angle of the buckle groove 43 is greater than 180°. A buckle column 51 is provided at the bottom of the insulator tester 5, and an anti-skid layer is provided on the outer side of the buckle column 51. The buckle column 51 is located in the buckle groove 43, and the anti-skid layer contacts the side wall of the buckle groove 43. With the cooperation of the buckle column 51 and the buckle groove 43, the insulator tester 5 is stably arranged on the support plate 42, and at the same time, it is convenient for the staff to quickly disassemble and assemble the insulator tester 5 and the support plate 42 according to needs. When the staff is located at the side of the insulator string, the insulator tester 5 can be adjusted to be in the same straight line with the operating rod, so that the probe of the insulator tester 5 can be controlled to contact the two ends of the insulator. When the staff is located above the insulator string, the insulator tester 5 is disassembled and the position of the insulator tester 5 relative to the operating rod is adjusted so that the insulator tester 5 and the operating rod are arranged vertically. Then, the operating rod can be placed parallel to the insulator string, and the probe of the insulator tester 5 contacts the two ends of the insulator. At this time, the operating rod does not need to be tied to the staff's waist, because the staff only needs to pull up and down the operating rod, and the arm will not feel pain due to the inclined pulling of the operating rod. In order to ensure that the insulator tester 5 can be stably placed relative to the support plate 42, a bolt can be threaded through the support plate 42, and the end of the bolt is forced to press against the side of the insulator tester 5, thereby forcing the insulator tester 5 to be stably placed.

For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
