Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tube leakage detection, in particular to a ceramic tube local leakage detection device. Background Art

[0002] Ceramic tubes are commonly known as ceramic discharge tubes in the power industry. Ceramic discharge tubes are connected in parallel in the circuit. When the voltage applied to the two electrode ends reaches a level that causes the gas in the gas discharge tube to break down, the gas discharge tube begins to discharge, changing from high impedance to low impedance, causing the surge voltage to quickly short-circuit to near zero voltage, and release the overcurrent into the ground, thereby protecting subsequent circuits. In order to prevent ceramic discharge tubes from working malfunctions, leakage detection of the ceramic discharge tubes is required.

[0003] For example, a leakage detector in the prior art, with publication number CN219957833U, comprises a body, on which two electric pens are plugged, the two electric pens consist of a hand-held rod and a measuring tip arranged at one end of the hand-held rod, the other ends of the two hand-held rods are connected to the body through connecting lines, and also comprises a storage mechanism arranged on the two hand-held rods for storing the measuring tips.

[0004] However, the device requires manual operation during use. However, ceramic discharge tubes are generally installed at a high position and are installed relatively densely. There are also a large number of electrical components distributed around them. Therefore, when operating, personnel need to get close to energized electrical components, which may cause the risk of electric shock. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a ceramic tube local leakage detection device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a local leakage detection device for a ceramic tube, comprising an electrical box and a ceramic discharge tube arranged on the outer wall of the electrical box, the outer wall of the electrical box is rotatably connected to a ring seat sleeved around the ceramic discharge tube, the outer wall of the ring seat is fixedly connected to an electric telescopic rod parallel to the ceramic discharge tube and with a telescopic stroke equal to the height of the ceramic discharge tube, the telescopic end of the electric telescopic rod is fixedly connected to a lifting plate, the lifting plate is at the same height as the ceramic discharge tube, and the bottom edge of the lifting plate is fixedly connected to a mounting seat, one side of the mounting seat is elastically slidably connected to a sliding seat, a leakage detector is arranged on the sliding seat, the leakage detector slides relative to the ceramic discharge tube, and the detection end of the leakage detector is embedded with a conductive ball rollingly connected.

[0007] Furthermore: the inner wall of the ring seat is fixedly connected with a ring rack, the inner wall of the electric box is fixedly connected with a motor, the main shaft of the motor passes through the wall of the electric box and is fixedly connected with a gear meshing with the ring rack.

[0008] Furthermore: the side of the ring seat facing the electric box is concave, and the ring rack and the gear are both located in the bottom depression of the ring seat.

[0009] Furthermore: a guide rod and a connecting rod penetrating the mounting seat are fixedly connected to one side of the sliding seat, and a spring with one end fixed to the surface of the connecting rod is embedded and fixedly connected to one side of the mounting seat.

[0010] Furthermore: an electric push rod is fixedly connected to the lifting plate, the electric push rod is distributed in parallel with the connecting rod, and a connecting block sleeved on the connecting rod is fixedly connected to the telescopic end.

[0011] Furthermore: the connecting rod is T-shaped, and the connecting block is located outside the mounting seat and fits with the head of the connecting rod.

[0012] Further: a rain shield is fixedly connected to the mounting base for protecting the leakage detector from rain.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the electric telescopic rod and the leakage detector are driven to rotate around the ceramic discharge tube by the rotation of the ring seat. Under the extension and retraction action of the electric telescopic rod, the lifting plate drives the leakage detector to rise and fall to any local position of the outer wall of the ceramic discharge tube. When the lifting plate is rotating or lifting, the conductive ball fits the outer wall of the ceramic discharge tube, so that the leakage detection of the ceramic discharge tube can be realized.

[0015] 2. In the utility model, the motor drives the gear to rotate, and then the meshing ring rack drives the ring seat to rotate, so that the lifting plate and the electric telescopic rod revolve around the ceramic discharge tube, and the gear and the ring rack are stored and hidden in the recess at the bottom of the ring seat, so they can avoid wind, sun and rain.

[0026] In this plan:

[0027] The electric telescopic rod 3 and the lifting plate 4 are driven to revolve around the ceramic discharge tube 2 by the rotation of the ring seat 5, so that the leakage detector 7 installed on the lifting plate 4 is rotated around the ceramic discharge tube 2, and under the telescopic action of the electric telescopic rod 3, the lifting plate 4 drives the mounting seat 11, the sliding seat 14 and the leakage detector 7 to be lifted or lowered to any local position of the outer wall of the ceramic discharge tube 2. By utilizing the elastic sliding of the sliding seat 14 and the mounting seat 11, and the rolling connection between the conductive ball 12 and the detection end of the leakage detector 7, the conductive ball 12 is attached to the outer wall of the ceramic discharge tube 2 during the rotation or lifting process of the lifting plate 4, so that the leakage detection of the ceramic discharge tube 2 can be realized.

[0028] like Figure 6 As shown: a ring rack 18 is fixedly connected to the inner wall of the ring seat 5, a motor 16 is fixedly connected to the inner wall of the electric box 1, the main shaft of the motor 16 passes through the wall of the electric box 1, and is fixedly connected to a gear 17 meshing with the ring rack 18.

[0029] The side of the ring seat 5 facing the electric box 1 is concave, and the ring rack 18 and the gear 17 are both located in the bottom concave part of the ring seat 5 .

[0030] In this plan:

[0031] The motor 16 drives the gear 17 to rotate, thereby realizing the meshing connection of the ring rack 18 to drive the ring seat 5 to rotate, so that the lifting plate 4 and the electric telescopic rod 3 revolve around the ceramic discharge tube 2, and the gear 17 and the ring rack 18 are stored and hidden in the recess at the bottom of the ring seat 5, so as to avoid wind, sun and rain.

[0032] like Figure 2 and Figure 4 As shown: a guide rod 15 and a connecting rod 9 penetrating the mounting seat 11 are fixedly connected to one side of the sliding seat 14, and a spring 13 having one end fixed to the surface of the connecting rod 9 is embedded and fixedly connected to one side of the mounting seat 11.

[0038] The rain shield 6 provided in addition can protect the detection end of the leakage detector 7 from rain and sun in daily situations.

[0039] Working principle: the motor 16 drives the gear 17 to drive the ring rack 18 to rotate, so that the ring seat 5 drives the electric telescopic rod 3, the lifting plate 4, the mounting seat 11, the sliding seat 14 and the leakage detector 7 to revolve around the ceramic discharge tube 2, and under the elastic action of the spring 13, the conductive ball 12 at the detection end of the leakage detector 7 is in close contact with the surface of the ceramic discharge tube 2. When the lifting plate 4 revolves, the electric telescopic rod 3 is extended to realize the lifting plate 4 driving the leakage detector 7 to rise and fall, so that the leakage detector 7 reaches any local position on the surface of the ceramic discharge tube 2 to perform leakage detection in the corresponding area.
