Description

Technical Field

[0001] The invention belongs to the technical field of tubular bus monitoring, and in particular relates to a tubular bus monitoring device. Background Art

[0002] The tubular busbar is one of the key equipment in the power transmission and transformation system. Limited by the installation environment of the tubular busbar, in most cases the tubular busbar is installed outdoors through a wire pole. Affected by the outdoor environment, the surface of the tubular busbar is prone to damage after long-term use. The damaged surface can be roughly manifested as two phenomena: convex surface or concave surface.

[0003] At present, the monitoring of the above phenomenon mostly relies on workers climbing onto the wire poles and walking along the tubular busbars to visually observe the surface conditions of the tubular busbars one by one, which makes the monitoring time-consuming and labor-intensive, and the monitoring effect is not good. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a tubular busbar monitoring device.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0012] As a further improvement of the present invention: the sleeve portion and the contact and pressure portion are connected via a transmission portion.

[0013] When the sleeve portion moves relatively along the top support portion, the transmission portion is used to drive the contact and pressure portion to move toward the top support portion and abut against one end of the top support portion. The contact and pressure portion can convert the pressure signal into an electrical signal and transmit it to the alarm to trigger an alarm message.

[0018] As a further improvement of the present invention: a pressure delivery part and a marking part are further provided inside the support part.

[0019] The pressure-feeding part contains air, and the marking part contains liquid pigment.

[0020] When the sleeve portion moves relative to the supporting portion, the air inside the pressure-feeding portion can be compressed and delivered to the inside of the marking portion. After the air enters the marking portion, the liquid pigment can be pushed out of the marking portion and act on the side wall of the tubular busbar to mark the tubular busbar.

[0021] As a further improvement of the present invention: the pressure-feeding portion includes a plunger barrel fixedly arranged on the inner wall of the support portion and a plunger rod movably arranged inside the plunger barrel,

[0027] In an embodiment of the present invention, the supporting portion is sleeved on the outside of the tubular busbar. Under the support of the elastic member, one end of the sleeve portion can be attached to the surface of the tubular busbar. The supporting portion is driven by the walking portion to move along the tubular busbar, and then the sleeve portion is driven to move along the surface of the tubular busbar. When there are protrusions or depressions on the surface of the tubular busbar, the sleeve portion can move relatively along the top support portion. At this time, the touch and pressure portion can be driven to move and touch the top support portion, thereby driving the alarm to send an alarm signal to remind the staff that there is an abnormality in the current surface position of the tubular busbar.

[0037] See also Figure 1 The present embodiment provides a monitoring device for a tubular busbar, comprising a walking portion 2, a supporting portion 3, a sleeve portion 4, a top supporting portion 5, an elastic member 6, a contact and pressure portion, and an alarm. The supporting portion 3 is movably sleeved on the outside of the tubular busbar 1, the top supporting portion 5 is fixedly arranged on the inner wall of the supporting portion 3, the sleeve portion 4 is movably arranged on one end of the top supporting portion 5 away from the inner wall of the supporting portion 3, the end of the sleeve portion 4 away from the top supporting portion 5 is in contact with the surface of the tubular busbar 1, and one end of the elastic member 6 is in contact with the inner wall of the supporting portion 3. The walking portion 2 is arranged inside the supporting portion 3, and is used to drive the supporting portion 3 to move along the tubular busbar 1. When the supporting portion 3 moves, the sleeve portion 4 can be driven to move along the surface of the tubular busbar 1. When the sleeve portion 4 moves compared to the top supporting portion 5, it can drive the touch-pressure portion to move and touch the top supporting portion 5, thereby driving the alarm to sound.

[0038] The supporting part 3 is sleeved on the outside of the tubular busbar 1. Under the support of the elastic member 6, one end of the sleeve part 4 can be attached to the surface of the tubular busbar 1. The supporting part 3 is driven by the walking part 2 to move along the tubular busbar 1, and then the sleeve part 4 is driven to move along the surface of the tubular busbar 1. When there are protrusions or depressions on the surface of the tubular busbar 1, the sleeve part 4 can move relatively along the top supporting part 5, and at this time, the touch and pressure part can be driven to move and touch the top supporting part 5, thereby driving the alarm to send an alarm signal to remind the staff that there is an abnormality in the current surface position of the tubular busbar 1.

[0039] See also Figure 3 In one embodiment, the sleeve portion 4 is connected to the contact and pressure portion via a transmission portion 8. When the sleeve portion 4 moves relatively along the top support portion 5, the transmission portion 8 is used to drive the contact and pressure portion to move toward the top support portion 5 and abut against one end of the top support portion 5. The contact and pressure portion can convert the pressure signal into an electrical signal and transmit it to the alarm to trigger an alarm message.

[0040] See also Figure 3 In one embodiment, the transmission part 8 includes an elastic rib 83, a limiting rod 82 and a limiting block 81, one end of the elastic rib 83 is hingedly connected to the inner wall of the sleeve part 4, and the other end is hingedly connected to the contact and pressure part, a limiting cavity 51 is opened inside the top support part 5, and the limiting block 81 is movably arranged inside the limiting cavity 51, one end of the limiting rod 82 extends into the limiting cavity 51 and is fixedly connected to the limiting block 81, and the elastic rib 83 is rotatably connected to the limiting rod 82.

[0041] When the sleeve part 4 moves normally along the surface of the tubular busbar 1, the limit block 81 is located at one end of the inner part of the limit cavity 51. When there is a protrusion on the surface of the tubular busbar 1, the sleeve part 4 acts on the protrusion to move away from the tubular busbar 1, thereby driving the contact and pressure part, the elastic rib 83 and the limit rod 82 to move synchronously. The limit block 81 moves along the inner part of the limit cavity 51, and the contact and pressure part can touch one end of the top support part 5 to convert the pressure signal into an electrical signal and transmit it to the alarm for alarm; when there is a depression on the surface of the tubular busbar 1, the sleeve part 4 acts on the depression. The recessed position can move toward the direction of the tubular busbar 1. Since the limit block 81 is limited at one end of the limit cavity 51, the limit rod 82 can provide a pulling force to the elastic rib sheet 83, so that the elastic rib sheet 83 is deflected and deformed by the force, so as to drive the contact and pressure portion to move toward the top support portion 5 and touch one end of the top support portion 5, so as to convert the pressure signal into an electrical signal and transmit it to the alarm for alarm. In this way, no matter whether there is a protrusion or a depression on the surface of the tubular busbar 1, the contact and pressure portion can move toward the top support portion 5 and interact with one end of the top support portion 5 to trigger the alarm.

[0042] In the above embodiment, the elastic rib 83 is made of metal or plastic, the elastic member 6 is a spring or a metal spring, the top support portion 5 is a columnar structure or a rod-shaped structure, the sleeve portion 4 is a sleeve structure or a columnar structure, and the elastic rib 83 is rotatably connected to the limiting rod 82 through a pin rod 84.

[0043] In another embodiment, the transmission part 8 may also include a bracket fixedly arranged at the end of the top support part 5, a gear rod fixedly arranged on one side of the bracket, a rocker arm overlapped on one side of the gear rod, and a pressure block fixedly arranged on the side wall of the sleeve part 4, one end of the rocker arm is hingedly connected to the contact and pressure part, and the other end extends to one side of the pressure block and is attached to the pressure block.

[0044] When there is a protrusion on the surface of the tubular busbar 1, the sleeve portion 4 acts on the protrusion to move away from the tubular busbar 1, thereby driving the touch-pressure portion and the pressure block to move synchronously, and the touch-pressure portion can touch one end of the top support portion 5 to convert the pressure signal into an electrical signal and transmit it to the alarm for alarm; when there is a depression on the surface of the tubular busbar 1, the sleeve portion 4 acts on the depression position and can move toward the tubular busbar 1 to drive the pressure block to move synchronously, and the pressure block can press one end of the swing rod, and under the restriction of the blocking rod, it can drive the swing rod to swing, thereby driving the touch-pressure portion to move toward the top support portion 5 and touch one end of the top support portion 5, so as to convert the pressure signal into an electrical signal and transmit it to the alarm for alarm, so that no matter there is a protrusion or a depression on the surface of the tubular busbar 1, the touch-pressure portion can move toward the top support portion 5 and interact with one end of the top support portion 5 to trigger an alarm.

[0045] See also Figure 3 In one embodiment, the contact and pressure portion includes a guide cylinder 41 fixedly arranged inside the sleeve portion 4, a mounting rod 85 telescopically fitted at one end of the guide cylinder 41, and a pressure sensor 86 arranged at one end of the mounting rod 85, and the elastic rib 83 is hingedly connected to the side wall of the mounting rod 85.

[0046] When the elastic rib 83 deflects and deforms, it can drive the mounting rod 85 to move toward the outside of the guide tube 42, and then drive the pressure sensor 86 to touch the end surface of the top support part 5 to generate an alarm.

[0047] In another embodiment, the contact and pressure portion may also include a sliding rod and a pressure sensor 86 connected to one end of the sliding rod. The inner wall of the sleeve portion 4 is provided with a guide rail that slides with the sliding rod. The elastic rib 83 is hingedly connected to the side wall of the sliding rod. When the elastic rib 83 is deflected and deformed, it can drive the sliding rod to move toward the top support portion 5, thereby driving the pressure sensor 86 to touch the end surface of the top support portion 5 to generate an alarm.

[0048] In the above embodiment, the connection between the touch pressure sensor 86 and the alarm belongs to the prior art and will not be described here in detail. The alarm may be a buzzer or a flash light.

[0049] See also Figure 1 In one embodiment, a roller 41 is rotatably provided at one end of the sleeve portion 4 away from the top support portion 5. When the sleeve portion 4 moves, the roller 41 rolls against the surface of the tubular busbar 1, thereby reducing the friction between the sleeve portion 4 and the tubular busbar 1 and ensuring the smoothness of movement.

[0050] See also Figure 1 and Figure 4 In one embodiment, a pressure-feeding portion 9 and a marking portion 7 are further provided inside the support portion 3, wherein air is stored inside the pressure-feeding portion 9, and liquid pigment is stored inside the marking portion 7. When the sleeve portion 4 moves relative to the top support portion 5, the air inside the pressure-feeding portion 9 can be pressed and delivered to the inside of the marking portion 7. After the air enters the marking portion 7, the liquid pigment can be pushed out of the marking portion 7 and act on the side wall of the tubular busbar 1 to mark the tubular busbar 1. According to the mark, the staff can quickly find the convex or concave position of the side wall of the tubular busbar 1 to determine the damaged position of the tubular busbar 1.

[0051] See also Figure 1 and Figure 4 In one embodiment, the pressure-feeding portion 9 includes a plunger barrel 92 fixedly arranged on the inner wall of the support portion 3 and a plunger rod 93 movably arranged inside the plunger barrel 92, a slide groove 94 is provided on the side wall of the plunger barrel 92, a connecting rod 95 is fixedly arranged on the side wall of the plunger rod 93, the connecting rod 95 extends from the slide groove 94 to the outside of the plunger barrel 93 and is connected to the sleeve portion 4, a first gas storage chamber is provided on both sides of the plunger rod 93, a first pipe 91 communicating with the first gas storage chamber is provided on the side wall of the plunger barrel 92, the marking portion 7 includes a material storage barrel fixedly arranged on the inner wall of the support portion 3 and a piston 71 movably arranged inside the material storage barrel, one end of the material storage barrel has a discharge port, liquid pigment is provided on the side of the piston 71 facing the discharge port, and a second gas storage chamber is provided on the side of the piston 71 away from the discharge port, the two groups of first gas storage chambers are connected to the second gas storage chambers through a second pipe 96, and a one-way valve is provided on the first pipe 91 and the second pipe 96.

[0052] When the sleeve portion 4 moves relative to the top support portion 5, the connecting rod 95 can drive the plunger rod 93 to adaptively move inside the plunger tube 92, thereby squeezing the air inside the corresponding first air storage chamber. Due to the presence of the one-way valve, air can enter the second air storage chamber through the second pipe 96 to push the piston 71 to move, thereby squeezing the liquid pigment, so that the liquid pigment is output from the discharge port and acts on the side wall of the tubular busbar 1, realizing the position marking of the tubular busbar. The marking is made according to the movement of the sleeve portion 4. In this way, it can be ensured that there is a protrusion or depression on the surface of the tubular busbar 1 near the marked position. The staff can search for the protrusion or depression according to the marked position, so that people can quickly find the damaged position of the tubular busbar 1.

[0053] In another embodiment, the pressure-delivery portion 9 may further include two groups of airbags arranged inside the support portion 3, the two groups of airbags are placed opposite to each other, a pressure plate is fixedly provided on the side wall of the sleeve portion 4, the pressure plate extends between the two groups of airbags, one side of the two groups of airbags are provided with an air nozzle, and the other side is provided with an air tube, and the air nozzle and the air tube are provided with a one-way valve, the marking portion 7 may further include a syringe, a rubber stopper is movably provided inside the syringe, the liquid pigment is encapsulated on one side of the rubber stopper, and the air tube is connected to a chamber on the side of the rubber stopper away from the liquid pigment.

[0054] When the sleeve portion 4 moves relative to the top support portion 5, the pressure plate can be driven to move synchronously, and the pressure plate can adaptively press a group of air bags, so that the air inside the air bags enters the syringe from the air tube, and then pushes the rubber stopper to press the liquid pigment out of one end of the syringe and act on the side wall of the tubular busbar 1, thereby marking the tubular busbar 1.

[0055] In one embodiment, the walking part 2 includes a driving motor and a walking wheel arranged at the output end of the driving motor, the driving motor is fixedly installed inside the supporting part 3, and the walking wheel is in contact with the side wall of the tubular busbar 1.

[0056] The driving motor drives the running wheel to rotate, and the friction between the running wheel and the tubular busbar 1 is used to drive the support part 3 to move along the tubular busbar 1 .

[0057] In another embodiment, the walking part 2 includes a rotating wheel rotatably arranged inside the supporting part 3, a plurality of permanent magnet sheets fixedly arranged on the side walls of the rotating wheel, and an electromagnetic sheet fixedly arranged inside the supporting part 3. The permanent magnet sheets are relatively distributed with an inclination, and the permanent magnet sheets are in contact with the side walls of the tubular busbar 1. By energizing the electromagnetic sheets, the repulsive effect between the electromagnetic sheets and the permanent magnet sheets is utilized to drive the rotating wheel to rotate, thereby driving the permanent magnet sheets to rotate, and the friction between the permanent magnet sheets and the tubular busbar 1 is utilized to drive the supporting part 3 to move along the tubular busbar.

[0058] See also Figure 2 In one embodiment, the support portion 3 includes a clamping cylinder, and a channel is provided inside the clamping cylinder for the tubular busbar 1 to pass through. To facilitate the installation of the support portion 3, the support portion 3 can also include two groups of arc-shaped sandwich shells, one end of the two groups of sandwich shells are hinged to each other, and the other end can be connected by a buckle or a screw.

[0059] In the embodiment of the present invention, the support portion 3 is sleeved on the outside of the tubular busbar 1. Under the support of the elastic member 6, one end of the sleeve portion 4 can be attached to the surface of the tubular busbar 1. The support portion 3 is driven by the walking portion 2 to move along the tubular busbar 1, and then the sleeve portion 4 is driven to move along the surface of the tubular busbar 1. When there are protrusions or depressions on the surface of the tubular busbar 1, the sleeve portion 4 can move relatively along the top support portion 5. At this time, the touch and pressure portion can be driven to move and touch the top support portion 5, thereby driving the alarm to send an alarm signal to remind the staff that there is an abnormality in the current surface position of the tubular busbar 1. Compared with the prior art, the damage defects such as protrusions and depressions on the side wall of the tubular busbar 1 can be effectively monitored, and the monitoring effect is good.
