Description
Technical Field
[0001] The utility model relates to the technical field of vibration detection, in particular to a breeze vibration sensing device for a power transmission line. Background Art
[0002] Breeze vibration is a high-frequency, low-radius vibration phenomenon in a vertical plane generated when the wind speed is not high. The transmission line will resonate in the vertical plane, forming a regular up and down wave-like reciprocating motion. Although the energy and amplitude of breeze vibration are not large, the vibration time is very long. If the line is in this state of repeated twists and turns for a long time, it is easy to reduce the fatigue strength of the line, damage the insulating material, and eventually cause the wire to break or be damaged, thereby causing safety hazards such as fire and electric shock.
[0003] Generally, the hazard is discovered after fatigue occurs and the line breaks, at which time the line hazard is already serious. At the same time, the damage caused by breeze vibration is somewhat hidden, often starting from the inner layer of the wire, and is not easy to detect during line inspection. Therefore, the present application provides a transmission line breeze vibration sensing device to meet the needs. Utility Model Content

At the same time, the damage caused by breeze vibration is relatively hidden, often starting from the inner layer of the wire, and is not easy to be detected during line inspection.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] A power transmission line breeze vibration sensing device comprises two semicircular rings, one end of the semicircular ring is provided with a first slot, the top and bottom of the first slot are provided with round holes, the other end of the semicircular ring away from the first slot is provided with a slide groove and a mounting mechanism, the two semicircular rings can be mounted on a power pole through the first slot and the mounting mechanism, the middle of the semicircular ring is fixedly connected with a connecting block, the top of the connecting block is fixedly connected with a plate, the plate is provided with a groove for allowing a power transmission line to pass, the top of the plate is rotatably connected with a pressure cover, one side of the plate is fixedly connected with a vibration sensor, the vibration sensor Two sensing columns extending to both sides of the groove are fixedly connected to one side of the device close to the groove, and the mounting mechanism includes a sliding cover, which is slidably connected to the semicircular ring, and a conical second groove is provided at one end of the sliding cover away from the first groove, and a spring is arranged inside the sliding groove, and both ends of the spring are fixedly connected to sliders extending out of the sliding groove, and a round block passing through the semicircular ring is fixedly connected to the side of the slider away from the spring, and the round block is adapted to the round hole, and a transmission block is fixedly connected to the side of the slider close to the sliding cover, and one end of the transmission block is an inclined surface and fits with the second groove on the sliding cover.
[0007] Preferably, both sides of the connection block are fixedly connected with connection bars, and one end of the connection bar away from the connection block is fixedly connected with the plate for the passage of other power transmission lines.
[0008] Preferably, a limiting block is fixedly connected in the middle of the slide groove, and the limiting block is used to divide the slide groove to prevent the sliding blocks from contacting each other when sliding, causing the round block to fall out of the slide groove.
[0009] Preferably, the top, bottom and sides of the sliding cover are all fixedly connected with anti-slip pads.
[0010] Preferably, an insulating pad is installed inside the groove on the plate to allow a power transmission line to pass through.
[0011] Preferably, a plurality of counters are fixedly connected to one side of the connection block that is away from each other, and the counters are electrically connected to the vibration sensor and display data of the vibration sensor.
[0012] Compared with the prior art, the utility model has at least the following beneficial effects:
[0013] In the above scheme, by providing the first slot and the installation mechanism, when it is necessary to connect one end of the two semicircular rings together, first slide the sliding cover on one of the semicircular rings to slide the sliding cover in the direction of the slot, and the inclined surface on the transmission block will stick to the conical second slot on the sliding cover and slide, so that the two sliders are close to each other through the sliding of the transmission block, squeezing the spring, and driving the round block to approach the inside of the slot. When the round block is flush with the semicircular ring, the end of the other semicircular ring with the first slot is connected to it, and then the sliding cover can be released, the spring rebounds and resets, so that the sliders move away from each other, driving the round block to pass through the semicircular ring, and the round block passes through the semicircular ring and is connected to the other semicircular ring. By fitting the round hole of the first card slot on the upper plate, the two semi-circular rings can be connected. The advantage of this is that the installation is simple and quick. Moreover, one end of the two semi-circular rings can be connected on the ground first, and then the pole can be climbed with the semi-circular rings. The other ends of the two semi-circular rings can be connected at the top of the pole to completely fix it on the pole. At the same time, the pressure cover can be turned to open the top of the plate, and the line can be inserted into the insulating pad in the groove of the plate before the pressure cover is reset to complete the installation. No additional tools are required, which reduces the installation steps of the staff on the pole, prevents the installation from being too complicated when the lines on the pole are messy, resulting in too much time and energy consumption, and reduces the danger.
[0014] By setting up vibration sensors and sensor poles, when wind blows, the line shakes and touches the sensor pole. The vibration sensor senses that the sensor pole is touched and transmits the data to the counter. When the staff patrols the line, they only need to check the value of the counter to effectively understand the vibration frequency of the transmission line and detect the degree of wear of the wire in time, preventing the damage to the inner layer of the wire from going unnoticed and only being discovered after the wire breaks due to fatigue.
