Description

Technical Field

[0001] The present invention relates to the technical field of power grid security early warning, and in particular to a power grid security early warning device and system. Background Art

[0002] In order to ensure the safe operation of the power grid, it is often necessary to conduct power grid safety warning work on the power grid. The invention patent with patent application number CN201910320370.6 discloses a real-time safety warning device for a smart grid. By setting a probe and an insulating cloth, a support spring pushes the support platform so that the top of the probe is inserted into the damaged part, and at the same time, the top of the hinged rod is pushed to rotate in the direction close to the ring, so that the hinged rod is detached from the hoop. The two hoop drives the insulating cloth to curl on the outside of the power grid to wrap the power grid, which can achieve rapid disposal of the damaged power grid and prevent the occurrence of leakage accidents. According to the technical solution disclosed by it, when the existing power grid safety warning mechanism is used, on the one hand, it cannot move autonomously, and often consumes electrical energy during the movement process, thereby increasing the consumption of electrical energy. On the other hand, when there is ice and snow on the cable, it not only makes the equipment unable to move, but also easily causes damage to the cable due to the pressure of ice and snow. On the other hand, it is impossible to quickly locate the faulty cable, and personnel are often required to query the location, which reduces the maintenance efficiency. Summary of the invention

[0008] Furthermore, the fan blade is installed at the bottom of the outer sleeve through a bearing, the gear one is welded to the top of the fan blade, a sliding sleeve is welded to the bottom of the outer sleeve, the rotating rod is clamped on the inner side of the sliding sleeve, the gear two is welded to one end of the rotating rod, the gear one is meshed with the gear two, a connecting rod is installed on the top of the gear one, and both ends of the connecting rod are installed on the gear two through bearings.

[0009] Furthermore, a support plate is installed on the outer side of the rotating rod, and the support plate is installed on the rotating rod through a bearing. A second spring is installed on the bottom of the support plate, and both ends of the second spring are respectively installed on the outer sleeve and the support plate through bearings.

[0010] Furthermore, one end of the rotating sleeve is installed on the inner side of the outer sleeve through a bearing, and the rotating sleeve is located at both ends of the inner sleeve. Gear three is welded to one end of the rotating sleeve, and the other end of the rotating rod is welded to gear four.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the power grid safety early warning device and system are in use, the wind blades are blown by the wind, and the gear 1 drives the gear 2, and the gear 2 drives the gear 4 through the rotating rod, and then the gear 3 drives the rotating sleeve to rotate. At the same time, the piston squeezes the hydraulic oil in the cylinder into the inner side of the support sleeve, and the movable plate squeezes the spring 3, so that the roller is clamped on the outer side of the cable. At the same time, the angle between the roller and the cable is less than 90 degrees, so that when the roller rotates on the cable, it will move spirally on the outer side of the cable, thereby driving the device to move. When the device moves to one end of the cable and cannot move, the gear The first pushes gear two, and gear two pushes the rotating rod. The support plate passes over the bottom of spring two, so that spring two squeezes the rotating rod in the opposite direction, and drives another gear two to mesh with gear one through the connecting rod, thereby driving another rotating sleeve to rotate on the cable, moving the equipment in the opposite direction. The position of the piston in the cylinder moves with it, so that the roller that does not participate in the drive is separated from the cable, avoiding the roller from generating resistance to the movement of the equipment. It can automatically use natural wind to drive the equipment to move back and forth on the cable, so as to perform real-time inspection of the cable without consuming electricity, thus saving energy consumption.

[0016] 2. When the power grid safety early warning device and system are moving, the pointed cone on the rotating sleeve rotates with the rotating sleeve to clear the ice and snow attached to the cable. This can not only prevent the ice and snow from blocking the movement of the equipment and ensure the power grid safety early warning work, but also avoid damage to the cable caused by the accumulation of ice and snow and ensure the safety of the cable.

[0017] 3. When the power grid safety early warning device and system are in use, the card board is stuck on the outer side of the cable, and a pair of pressure sensors are used to generate pressure through springs, which is transmitted to the intelligent processor to calculate the diameter of the cable. When there is a gap on the cable or the diameter becomes smaller due to stretching, the pressure on the pressure sensor is reduced, and the diameter calculated by the intelligent processor is smaller than the diameter of the standard cable. The information is then sent to personnel through the information transceiver, and the electromagnet is turned on at the same time. The electromagnet drives the clamp to be fixed at the abnormal position of the cable, and the locator sends positioning information to facilitate personnel to find the abnormal position of the cable in time, so that personnel can carry out maintenance work in time.
