Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to an alarm linkage device used in transformer substations. Background Art

[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. It plays the role of transit and transformation in the circuit system and is an important part of the power grid system. Therefore, inspections inside the substation are crucial to the maintenance and operation of the power grid system. The distance between the two ends of the transmission line is long, and it is impossible to detect whether the line is damaged in real time.

[0003] For example, the authorization announcement number "CN217718741U" is named as a substation intelligent patrol alarm linkage device. Although it stops moving when encountering a damaged transmission line and triggers the induction alarm device to remind the staff to carry out repairs, and the angle of the camera can be adjusted by bolts as needed to provide real-time monitoring for the staff, the existing substation intelligent patrol alarm linkage device needs to wait for the sleeve on the outside of the transmission line to position the transmission line, and move the equipment on the transmission line through the rotating roller, but because it only relies on the rotating roller on one side to play a driving role, the friction between the roller and the transmission line determines the effect of the equipment movement. When the surface of the transmission line is relatively smooth in winter or foggy days and cannot produce effective friction with the roller, the equipment will be stuck on the transmission line and difficult to move forward, which interferes with the use of the substation intelligent patrol alarm linkage device. The scope of use is easily restricted by the environment, which reduces the working effect of the substation intelligent patrol alarm linkage device.

[0004] At the same time, the existing substation intelligent inspection alarm linkage device needs to set the alarm linkage device on the transmission line of the substation, and then identify and detect the damaged transmission line as the substation intelligent inspection alarm linkage device moves. After the damaged transmission line target is found, the device will stop running and alarm to remind the operator to deal with it before continuing to move forward. This means that when there are many damaged locations in the substation transmission line, the existing substation intelligent inspection alarm linkage device needs to suspend work many times, which greatly prolongs the working time and process, and also requires the personnel who repair the transmission line to frequently and repeatedly walk between the damaged transmission lines, increasing the workload, and ultimately affecting the working efficiency of the substation intelligent inspection alarm linkage device. Utility Model Content

[0005] The utility model aims to solve the problems of poor use effect and low working efficiency of the intelligent patrol alarm linkage device of the substation, and proposes an alarm linkage device for the substation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an alarm linkage device for a substation, comprising an alarm linkage device body, an alarm linkage device control terminal and a camera, wherein a double-sided friction-enhanced transmission line movable structure is arranged inside the alarm linkage device body, and the double-sided friction-enhanced transmission line movable structure comprises a motor, a support frame and a friction roller, wherein the motor is fixedly mounted on the top of the alarm linkage device body, and the output shaft of the motor is fixedly connected with a driving gear, and a plurality of the support frames are fixedly mounted inside the alarm linkage device body, and a driving shaft is rotatably connected to one side of the internal part of the plurality of the support frames, and the top of the driving shaft is fixedly connected to the lower end of the driving gear, and a driven shaft is rotatably connected to the other side of the internal part of the plurality of the support frames, and a driven gear is fixedly sleeved on the top of the driven shaft, and one side of the driven gear is meshed and connected with one side of the driving gear, and two friction rollers are fixedly connected to the outer sides of the driving shaft and the driven shaft.

[0008] Preferably, a wire inlet groove is fixedly provided at the bottom end of the main body of the alarm linkage device, and the top end of the wire inlet groove is connected to the lower end of the wire through hole.

[0009] Preferably, a balance detection positioning mark structure is provided at the bottom end of the main body of the alarm linkage device;

[0010] The balance detection positioning mark structure includes a connecting block, a hollow ball and a solenoid valve;

[0011] The two connecting blocks are fixedly installed at the bottom end of the alarm linkage device body, two hollow balls are fixedly installed at the lower ends of the two connecting blocks, two filling holes are fixedly opened above the two hollow balls, two marking tubes are fixedly connected to the bottom ends of the two hollow balls, and solenoid valves are fixedly installed inside the two marking tubes.

[0012] Preferably, a structure that facilitates carrying is provided on the outer side of the main body of the alarm linkage device;

[0013] The portable structure includes side panels, limit blocks and handles;

[0014] The two side panels are fixedly mounted on the outer wall of the alarm linkage device body, the outer sides of the two side panels are fixedly connected with limit blocks, the outer sides of the two limit blocks are fixedly sleeved with vertical panels, and the handles are fixedly connected to the inner sides of the two vertical panels.

[0016] The utility model proposes an alarm linkage device for a substation, which has the beneficial effect of placing the end of the transmission line to be detected and alarmed into the inside of the main body of the alarm linkage device along the line feeder groove, and then manually forcing the rubber friction roller to deform and clamp the transmission line through external force, and the motor will drive the driving shaft at the lower end to rotate through the output shaft, and the two relatively rotating driving shafts and driven shafts will drive the two friction rollers to rotate in opposite directions, and the friction rollers will drive the alarm linkage device main body to translate on the transmission line, and the alarm linkage device structure with two sides clamped on the transmission line for driving and moving is utilized to improve the use effect of the alarm linkage device for the substation.

[0017] When the alarm linkage device detects that a transmission line is damaged somewhere, the alarm linkage device control terminal will connect the power supply to start the solenoid valve. The solenoid valve will open and allow the marking color paint stored inside the hollow ball to flow out along the marking tube. The maintenance personnel only need to find the position where the color paint flows out of the marking tube to repair the damaged transmission line. The structure of making a mark and then moving forward to inspect and alarm is used to reduce working time and the workload of operators, thereby improving the working efficiency of the alarm linkage device used in substations.

The friction rollers 67 are made of a hard rubber material with a large number of vertical lines on the outer wall. The two friction rollers 67 are designed to be in the shape of a diabolo. The inner sides of the two relatively diabolo-shaped friction rollers 67 will roll and translate along the transmission line using the friction force of rotation. When the alarm linkage device body 1 needs to be used on the transmission line of the substation, the end of the transmission line to be detected and alarmed is placed inside the alarm linkage device body 1 along the line inlet groove 4, and then the transmission line of the substation will be flush with the height position of the line through hole 5;

[0028] At this time, the rubber friction roller 67 is manually forced to deform and clamp the power transmission line through external force, and the power supply is connected to start the motor 61. The motor 61 will drive the driving shaft 64 at the lower end to rotate through the output shaft. The driving shaft 64 uses the meshing driving gear 62 and the driven gear 65 to drive the driven shaft 66 to rotate inside the support frame 63. The two relatively rotating driving shafts 64 and driven shafts 66 will drive the two friction rollers 67 to rotate in opposite directions. The friction rollers 67 will drive the alarm linkage device body 1 to move horizontally on the power transmission line to facilitate the detection work. The two ends of the alarm linkage device body 1 are fixed with wire holes 5. The inner sides of the two wire holes 5 are arranged opposite to the middle of the two friction rollers 67. The bottom end of the alarm linkage device body 1 is fixed with a wire feed slot 4, and the top of the wire feed slot 4 is connected to the lower end of the wire feed slot 5.

[0029] The friction roller 67 is made of a hard rubber material with a plurality of vertical lines on the outer wall. The two friction rollers 67 are designed to be in the shape of a diabolo.

Then the transmission line of the substation will be flush with the height position of the line through hole 5. At this time, the friction roller 67 made of rubber is manually forced to deform by external force to clamp the transmission line.

[0030] Connect the power supply to start the motor 61, and the motor 61 will drive the driving shaft 64 at the lower end to rotate through the output shaft. The driving shaft 64 drives the driven shaft 66 to rotate inside the support frame 63 by means of the meshing driving gear 62 and the driven gear 65. The two relatively rotating driving shafts 64 and driven shafts 66 will drive the two friction rollers 67 to rotate in opposite directions. The friction rollers 67 will drive the alarm linkage device body 1 to translate on the transmission line, which is convenient for the detection work. The alarm linkage device structure that is clamped on both sides and driven to move on the transmission line is used to improve the use effect of the alarm linkage device used in the substation.

After marking, the solenoid valve 74 is closed, and the alarm linkage device body 1 continues to move forward. At this time, the alarm linkage device control terminal 2 will notify the maintenance personnel to work through the circuit.
