Description

Technical Field

[0001] This utility model patent belongs to the field of circuit maintenance technology, and in particular relates to a retractable and operable power insulation connecting rod for use in pipe wells. Background Technology

[0002] An electrical insulating connecting rod is an insulating tool specifically designed for use in power systems. It is mainly used for live-line work, live-line inspection, and live-line maintenance to protect the safety of electrical workers.

[0003] Power maintenance personnel need to regularly enter underground cable transmission ducts for inspection or maintenance. However, the hydrogen sulfide and other toxic gases produced in the ducts due to the lack of air circulation over the years can pose a life-threatening risk to the personnel. Therefore, it is necessary to use a telescopic insulated connecting rod to perform non-contact operation on the underground equipment.

[0004] Because existing pipe wells consist of a vertical wellhead section and a horizontal pipe section, and the existing telescopic insulated connecting rods can only extend and retract in the horizontal direction, it causes inconvenience for live work inside the pipe wells. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model patent provides an insulated telescopic rod for pipeline wells, used for telescopic live-line work inside pipeline wells.

[0006] The technical solution adopted by this utility model patent to solve its technical problem is: an insulated telescopic rod for pipeline wells, including an insulated connecting rod and a telescopic operating rod connected to the insulated connecting rod through a connector. The telescopic operating rod includes a fixed rod and a telescopic rod inserted into the fixed rod. The fixed base includes a first fixed base and a second fixed base respectively fixed on the fixed rod and the insulated connecting rod. Two guide wheels are installed side by side on the first fixed base, and a guide wheel and a detection device are installed on the second fixed base. The bottom of the fixed rod has a sliding groove, and a pull ring connected to the telescopic rod is in the sliding groove. One end of the traction rope passes through the lower guide wheel of the first fixed base and the upper guide wheel of the second fixed base in sequence, then passes through the pull ring and exits from the upper guide wheel of the first fixed base.

[0007] The aforementioned insulated telescopic rod for pipeline wells comprises an insulated connecting rod consisting of a first connecting rod and a second connecting rod made of epoxy resin pipes, with threaded portions and threaded sleeves respectively provided at the corresponding ends of two adjacent epoxy resin pipes.

[0008] The aforementioned insulated telescopic rod for pipe wells has a second fixed seat mounted on a first connecting rod, and a third fixed seat is also mounted on the second connecting rod, with a guide wheel mounted on the third fixed seat.

[0009] The aforementioned insulated telescopic rod for pipeline wells has a circular or square cross-section for both the fixed rod and the telescopic rod.

[0010] The aforementioned insulated telescopic rod for pipeline wells has a connector that is either an L-shaped connector with two sleeves fixedly connected or a universal joint with two sleeves movably connected.

[0011] The aforementioned insulated telescopic rod for pipeline wells has a detection device that is a camera or a searchlight.

[0012] The beneficial effects of this utility model patent are as follows: By cooperating with the guide wheel and the traction rope, the extension and retraction of the telescopic rod on the fixed rod can be achieved by pulling the two ends of the traction rope. By pulling the traction rope along the direction of the insulating connecting rod through the guide wheel on the fixed seat, the telescopic operating rod can be extended and retracted in a relatively vertical direction. When the telescopic rod is placed in the pipe well, and the telescopic operating rod is parallel to the pipe while the insulating rod is parallel to the well opening, the traction rope can be pulled outside the well opening. With the help of detection devices such as cameras or searchlights on the telescopic operating rod, live work inside the pipe can be achieved. Attached Figure Description

Detailed Implementation

[0016] The present utility model patent will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] Reference Figure 1 , Figure 2As shown, this utility model patent discloses an insulated telescopic rod for pipe wells, including an insulated connecting rod 1 and a telescopic operating rod 4 made of aluminum alloy square or round tube connected to the insulated connecting rod 1 via an L-shaped connector 6. Nylon guide wheels 7 are respectively mounted on the insulated connecting rod 1 and the telescopic operating rod 4 via fixed seats 3, and an insulated traction rope 5 is threaded through the guide wheels 7. The telescopic operating rod 4 includes a fixed rod 41 and a telescopic rod 42 inserted into the fixed rod 41. The fixed seat 3 includes a first fixed seat respectively fixed to the fixed rod 41 and the insulated connecting rod 1. The first fixed base 31 and the second fixed base 32 are equipped with two guide wheels 7 installed side by side on the first fixed base 31 and a guide wheel 7 and a detection device 10 installed on the second fixed base 32. The detection device 10 can be a wired or wireless camera or a searchlight. The bottom of the fixed rod 41 is provided with a sliding groove 8. The sliding groove 8 contains a pull ring 9 connected to the telescopic rod 42. The traction rope 5 passes through the lower guide wheel 7 of the first fixed base 31 and the upper guide wheel 7 of the second fixed base 32 in sequence, and then passes through the pull ring 9 and exits from the upper guide wheel 7 of the first fixed base 31.

[0018] The insulating connecting rod 1 is composed of multiple epoxy resin tubes. The corresponding ends of two adjacent epoxy resin tubes are respectively provided with threaded parts and threaded sleeves 2, so that the insulating connecting rod 1 of different lengths can be selected according to different wellhead depths.

[0019] The telescopic rod 42 is equipped with a special tool such as a clamp or scissors at its end.

[0020] As a further embodiment, the insulating connecting rod 1 is composed of a first connecting rod 11 and a second connecting rod 12 made of epoxy resin tubes. The corresponding ends of two adjacent epoxy resin tubes are respectively provided with threaded parts and threaded sleeves 2. The second fixing seat 32 is installed on the first connecting rod 11. A third fixing seat 33 is also installed on the second connecting rod 12. A guide wheel 7 is installed on the third fixing seat 32, which can guide and constrain the tail of the traction rope 5 and prevent the excessively long traction rope 5 from swaying during use. At this time, the traction rope 5 passes through the lower guide wheel 7 of the first fixing seat 31, the lower guide wheel 7 of the third fixing seat 33, and the upper guide wheel 7 of the second fixing seat 32 in sequence, and then passes through the pull ring 9 and exits from the upper guide wheel 7 of the first fixing seat 31, connecting the ends.

[0021] The connector 6 can be an L-shaped connector that fixes two casings together, or it can be a universal joint that movably connects two casings together. That is, the included angle between the two casings is no longer 90°, but can be other fixed angles, or the angle can be set to be adjustable. It is suitable for adjusting the angle between the insulating connecting rod 1 and the telescopic operating rod 4, so as to facilitate the entry and exit of the wellhead for pipeline well operations.

[0022] The above embodiments are merely illustrative of the principles and effects of this utility model patent, as well as some of the application embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model patent, and these all fall within the protection scope of this utility model patent.
