Description

Technical Field

[0001] This utility model relates to the field of wind deflection detection technology for high-voltage transmission line conductors, and in particular to a wind deflection detection mechanism for high-voltage transmission line conductors. Background Technology

[0002] A high-voltage transmission line conductor wind deflection detection device is used to monitor the deviation of high-voltage transmission line conductors under wind force. Wind deflection can reduce the distance between the conductor and surrounding objects such as poles, trees, and buildings, and in severe cases, it may cause accidents such as discharge flashover, affecting the safe operation of the power system. This detection device can promptly grasp the wind deflection status of the conductor so that appropriate measures can be taken.

[0003] A search of the Chinese patent "Device for Wind Deflection Angle of High-Voltage Overhead Line Conductors in Narrow Urban Areas" (authorization announcement number "CN218955747U") reveals that this patent uses a reset spring to move a limit rod and a pull block, causing the limit rod to engage in a limit hole, thereby locking the trapezoidal block onto a U-shaped mounting plate. This allows the limit detection device to detect wind deflection of the high-voltage transmission line conductors.

[0004] In the aforementioned application, the impact force of wind on the conductor is easily transmitted to the return spring. Because the return spring is elastic, it can easily cause the trapezoidal block to shift on the U-shaped mounting plate, thereby affecting the effectiveness of the conductor wind deflection detection.

[0005] Therefore, a high-voltage transmission line conductor wind deflection detection mechanism is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-voltage transmission line conductor wind deflection detection mechanism to solve the above problems. It improves the problem that the wind impact force on the conductor is easily transmitted to the return spring, and because the return spring has elasticity, it is easy for the trapezoidal block to deviate on the U-shaped mounting plate.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a high-voltage transmission line conductor wind deflection detection mechanism, comprising: a detection frame, wherein a safety frame is hinged to the upper end of the surface of the detection frame; an anti-loosening mechanism, wherein the anti-loosening mechanism includes bolts threaded to both sides of the inner wall of the safety frame, the surface of the bolts being threaded to the inner wall of the detection frame, a blocking block being slidably connected to both sides of the inner wall of the safety frame, a first spring being fixedly connected to one side of the blocking block, the other end of the first spring being fixedly connected to the inner wall of the safety frame, a slider evenly distributed in a row being fixedly connected to the front end of the blocking block, a connecting frame being slidably connected to the inner wall of the safety frame, and a plurality of moving blocks being fixedly connected to the rear end of the connecting frame. The frame is fixed to the detection frame by bolts, thus ensuring the wind deflection detection mechanism is stably installed on the conductor surface. The elastic force of the first spring pushes the blocking block to move, thereby limiting the contact of the top of the bolt. Through the cooperation of the slider, the moving block and the connecting frame, the blocking block can be moved in one direction, ensuring that the bottom of the blocking block is stably in contact with the top of the bolt, thus locking the bolt and ensuring that the wind deflection detection mechanism is firmly installed on the conductor, preventing the connection of the wind deflection detection mechanism from loosening under external impact.

[0008] Preferably, a second spring is fixedly connected to the front end of the connecting frame, and the other end of the second spring is fixedly connected to the inner wall of the mounting frame.

[0009] Preferably, a pull rope block is fixedly connected to one side of the shielding block, and the front end of the pull rope block penetrates and extends out of the inner wall of the frame.

[0010] Preferably, a support block is fixedly connected to the front end of the safety frame.

[0011] Preferably, the inner wall of the support block is slidably connected with a first stop and a second stop. Through the cooperation of the support block, the first stop, and the second stop, the rope block and the connecting frame are limited, thereby ensuring that the reserved hole on the safety frame is stably open, thus facilitating the installation of bolt threads in the detection frame and the safety frame.

[0012] Preferably, protective frames are fixedly connected to both sides of the detection frame, and ultra-clear glass is embedded in the inner wall of the protective frames. The protective frames and ultra-clear glass protect the displacement sensor and angle sensor on the detection frame, reducing the damage rate of the displacement sensor and angle sensor.

[0013] Preferably, rubber pads are fixedly connected to both sides of the inner wall of the detection frame and the safety frame, and the surface of the rubber pads is in the shape of a half-circle. The rubber pads increase the friction between the detection frame / safety frame and the wire, ensuring the stability of the wind deflection detection mechanism when mounted on the wire.

[0014] The beneficial effects of this utility model are:

[0015] 1. The mounting frame is fixed to the detection frame by bolts, thereby ensuring that the wind deflection detection mechanism is stably installed on the conductor surface. The elastic force of the first spring pushes the blocking block to move, thereby limiting the contact of the top of the bolt. Through the cooperation of the slider, the moving block and the connecting frame, the blocking block can be moved in one direction, ensuring that the bottom of the blocking block is stably contacting the top of the bolt. Compared with the existing wind deflection detection mechanism, which is prone to loosening under external impact, this method ensures that the wind deflection detection mechanism is firmly installed on the conductor by locking the bolt.

[0016] 2. By cooperating with the support block, the first stop block and the second stop block, the rope block and the connecting frame are limited, thereby ensuring that the reserved holes on the safety frame are stably open, so as to facilitate the installation of bolt threads in the detection frame and the safety frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-5As shown, a high-voltage transmission line conductor wind deflection detection mechanism includes: a detection frame 1, with a safety frame 2 hinged to the upper surface of the detection frame 1; an anti-loosening mechanism 3, which includes bolts 31 threaded to both sides of the inner wall of the safety frame 2, the surface of the bolts 31 threaded to the inner wall of the detection frame 1, a blocking block 32 slidably connected to both sides of the inner wall of the safety frame 2, a first spring 33 fixedly connected to one side of the blocking block 32, the other end of the first spring 33 fixedly connected to the inner wall of the safety frame 2, a series of equally arranged sliders 34 fixedly connected to the front end of the blocking block 32, a connecting frame 36 slidably connected to the inner wall of the safety frame 2, a plurality of moving blocks 35 fixedly connected to the rear end of the connecting frame 36, a protective frame 312 fixedly connected to both sides of the detection frame 1, ultra-clear glass embedded in the inner wall of the protective frame 312, and rubber pads 313 fixedly connected to both sides of the inner walls of the detection frame 1 and the safety frame 2, the surface of the rubber pads 313 being in the shape of a half-circle. The blocking block 32 is a rubber component, and the surfaces of the slider 34 and the moving block 35 are both right-angled triangles.

[0025] An angle sensor is fixedly connected to one side of the detection frame 1, and a displacement sensor is fixedly connected to the side of the detection frame 1 away from the angle sensor. Both the angle sensor and the displacement sensor are located inside the protective frame 312. A solar panel is embedded in the top of the safety frame 2. A solar controller, inverter, transmission module and data acquisition module are installed on the inner top wall of the safety frame 2. A battery is installed on the inner bottom wall of the detection frame 1.

[0026] The solar controller primarily functions to regulate and control the battery. It prevents the solar panels from overcharging the battery, thus avoiding shortened battery life or even damage due to overcharging; it also prevents the battery from over-discharging the load, protecting both the battery and the electrical equipment. Working principle: By detecting the battery voltage, the solar controller automatically cuts off the charging circuit when the battery voltage reaches the set overcharge protection value; when the battery voltage drops to the over-discharge protection value, it cuts off the discharging circuit.

[0027] Inverters use electronic circuits to convert direct current (DC) into alternating current (AC). Common types include sine wave inverters and square wave inverters. Sine wave inverters output AC waveforms that are closer to mains power, resulting in better compatibility with electrical equipment.

[0028] The battery powers the angle sensor, displacement sensor, and transmission module, while the solar panel, inverter, and solar controller convert sunlight into electrical energy which is stored in the battery.

[0029] When wind deflection testing is required on high-voltage transmission line conductors, a special tool such as an electric lift is used to lift the staff to a suitable height. The inner surface of the rubber pad 313 on the test frame 1 is then placed against the conductor surface. At this time, the safety frame 2 is pulled so that the inner surface of the rubber pad 313 on the safety frame 2 is placed against the conductor surface, and the bottom of the safety frame 2 is placed against the top of the test frame 1. At this time, an electric screwdriver is used to thread the bolt 31 into the safety frame 2 and the test frame 1, so that the safety frame 2 is fixed on the test frame 1. At this time, the elastic force of the first spring 33 pushes the blocking block 32 to move and abut against the top of the bolt 31. The movement of the blocking block 32 drives the slider 34 to move, so that the inclined surface of the slider 34 moves on the inclined surface of the moving block 35, thereby moving the blocking block 32 in one direction, so that the blocking block 32 is stably abutting against the top of the bolt 31.

[0030] The angle sensor and displacement sensor are automatically activated. When the conductor deviates due to wind, the angle sensor measures the change in the angle between the conductor and the vertical direction in real time. The sensor usually works based on the principle of gyroscope or accelerometer, which can convert the angle change into an electrical signal. The angle sensor transmits the measured electrical signal to the data acquisition module. After preliminary processing, the data acquisition module sends the data to the monitoring center via wireless communication. The software in the monitoring center analyzes the data and determines whether the wind deflection angle of the conductor exceeds the safety threshold.

[0031] When conductors are displaced by wind, displacement sensors measure the amount of displacement relative to their initial position. Common displacement sensors include resistive and inductive types. They convert displacement changes into electrical signals. Similar to angle sensors, the data from displacement sensors is collected and transmitted to the monitoring center for analysis to assess the severity of conductor wind deflection. This allows for timely detection of excessive conductor wind deflection, providing early warnings and preventing insufficient safe distances between conductors and objects such as poles, trees, and buildings due to wind deflection. This helps prevent short circuits, tripping, and other faults, ensuring the safe and stable operation of high-voltage transmission lines.

[0032] like Figure 4 As shown, a second spring 37 is fixedly connected to the front end of the connecting frame 36, and the other end of the second spring 37 is fixedly connected to the inner wall of the mounting frame 2. Both the first spring 33 and the second spring 37 are alloy spring steel components.

[0033] like Figure 4-5 As shown, a pull rope block 38 is fixedly connected to one side of the cover block 32. The front end of the pull rope block 38 penetrates and extends out of the inner wall of the mounting frame 2. A support block 39 is fixedly connected to the front end of the mounting frame 2. A first stop block 311 and a second stop block 310 are slidably connected to the inner wall of the support block 39. The pull rope block 38 includes a pull rope and a mounting block. One end of the pull rope is fixedly connected to one side of the cover block 32, and the other end of the pull rope away from the cover block 32 is fixedly connected to the rear end of the mounting block.

[0034] In use, this invention involves using a specialized tool, such as an electric lift, to elevate the operator to a suitable height. The inner surface of the rubber pad 313 on the detection frame 1 is then brought into contact with the surface of the conductor. At this point, the mounting frame 2 is pulled, causing the inner surface of the rubber pad 313 on the mounting frame 2 to contact the surface of the conductor, and the bottom of the mounting frame 2 to contact the top of the detection frame 1. An electric screwdriver is then used to thread the bolt 31 into the mounting frame 2 and the detection frame 1, fixing the mounting frame 2 to the detection frame 1. Finally, the second stop 310 and the first stop 311 are pulled upwards, thereby releasing the... In addition to limiting the pull rope block 38 and the connecting frame 36, the elastic force of the first spring 33 pushes the blocking block 32 to move and abut against the top of the bolt 31. The elastic force of the second spring 37 pushes the connecting frame 36 and the moving block 35 to move, so that the inclined surface of the moving block 35 abuts against the inclined surface of the slider 34. The movement of the blocking block 32 drives the slider 34 to move, so that the inclined surface of the slider 34 moves on the inclined surface of the moving block 35, thereby moving the blocking block 32 in one direction, so that the blocking block 32 stably abuts against the top of the bolt 31, thereby making the detection frame 1 and the safety frame 2 securely installed on the wire.

[0035] It should be noted that the detection frame 1, safety frame 2, angle sensor, displacement sensor, solar panel, solar controller, inverter, transmission module, data acquisition module, and battery mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the angle sensor, displacement sensor, solar panel, solar controller, inverter, transmission module, data acquisition module, and battery can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. 。
