[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0026] Based on the defects in the prior art, the following will be combined with specific drawings Figures 1-2 A preferred embodiment of the pressure wheel type overhead line clamp of the present application will be described in detail.
[0027] As Figures 1-2 shown, it is a structural schematic diagram of a preferred embodiment of the pressure wheel type overhead line clamp of the present application. The pressure wheel type overhead line clamp comprises a support seat 1, a sliding wheel 3 and an overhead rod 212. The support seat 1 is provided with a wire conveying channel 11. The sliding wheel 3 is cross provided in the wire conveying channel 11, that is, the sliding wheel 3 forms a certain angle with the wire conveying channel 11. Both ends of the sliding wheel 3 are rotatably provided on two side walls of the wire conveying channel 11. The overhead rod 212 is provided on the support seat 1, that is, the pressure wheel type overhead line clamp can be hung on the tower through the overhead rod 212.
[0028] The suspension rod 212 of the embodiment comprises a vertical rod 21 and a hanging shaft 22. The vertical rod 21 comprises four rods, which are arranged in a figure-of-eight structure on both sides of the support base 1 and are fixedly connected to the support base 1, that is, the vertical rod 21 cannot rotate relative to the support base 1. The hanging shaft 22 is installed between the figure-of-eight structures and is fixedly connected to the figure-of-eight structures. The hanging shaft 22 is directly installed on the tower.
[0029] When the conductor passes through the conductor conveying channel 11, the conductor can contact the sliding wheel 3 in the conductor conveying channel 11. When the conductor is dragged or subjected to pressure, the sliding wheel 3 can also rotate around the central axis.
[0030] In addition, in order to measure the pressure of the conductor on the sliding wheel 3, an elastic metal film 4 is coated on the outer wall of the sliding wheel 3. When the elastic metal film 4 is subjected to the force of the conductor, it will deform, thereby changing the resistance value. An electrode 5 is arranged at the end of the sliding wheel 3, and the elastic metal film 4 is electrically connected to the electrode 5. The electrode 5 is used to obtain the resistance value of the deformed elastic metal film 4.
[0031] When the conductor passes through the conductor conveying channel 11, the elastic metal film 4 on the outer wall of the sliding wheel 3 is extruded, and the elastic metal film 4 is subjected to the force of the conductor, which causes the elastic metal film 4 to deform and change its resistance value. Through the connection of the electrode 5 and the elastic metal film 4, the resistance value after deformation can be accurately obtained, thereby indirectly measuring the size of the pressure received, thereby reflecting the bearing capacity of the conductor.
[0032] In the resistance measurement, the electrode 5 is responsible for introducing and leading out the current of the elastic metal film 4. When the current passes through the elastic metal film 4, a voltage drop is generated, which is proportional to the resistance value and the current size. By measuring the voltage drop and the current value, and then using Ohm's law (R=V / I, where R is the resistance, V is the voltage drop, and I is the current), the resistance value is calculated.
[0033] In the embodiment, the support base 1 is arc-shaped, which comprises two opposite edges 12, and the conductor conveying channel 11 is formed between the two opposite edges 12. Since the support base 1 is arc-shaped as a whole, the conductor conveying channel 11 and the edges 12 are also arc-shaped.
[0034] The arc-shaped conductor conveying channel 11 can reduce the friction between the conductor and the conductor conveying channel 11, that is, the friction between the conductor and the elastic metal film 4, thereby reducing the interference of the conductor on the pressure of the elastic metal film 4 and improving the accuracy of the measurement.
[0035] As a preferred embodiment, continuing to refer to Figure 1As shown, the device further comprises a smart integrated transmitting chip 6, which is arranged in the arc of the support base 1 and is electrically connected to the electrode 5, and is used to transmit the acquired resistance value to the control end.
[0036] In this way, the measured resistance value (or converted pressure value) is transmitted to the computer or mobile phone in real time through the smart integrated transmitting chip 6, providing the user with the ability to monitor the data in real time, facilitating data analysis, early warning, and decision-making.
[0037] The smart integrated transmitting chip 6 is of WS4460 model or XL4456 model.
[0038] As a preferred embodiment, the device further comprises a power module connected to the smart integrated transmitting chip 6, which is used to provide a stable working voltage for the smart integrated transmitting chip 6.
[0039] The power module is a rechargeable battery or a solar power module, which can be easily charged or powered by solar energy.
[0040] As a preferred embodiment, the elastic metal film 4 is wrapped around the entire arc-shaped outer wall of the dumbbell-shaped sliding wheel 3.
[0041] By wrapping the elastic metal film 4 around the entire arc-shaped outer wall of the dumbbell-shaped sliding wheel 3, the accuracy of measuring the resistance value of the elastic metal film 4 is increased.
[0042] In addition, the sliding wheel 3 of the present embodiment is preferably in the shape of a dumbbell.
[0043] The dumbbell shape means that the two ends are large and the middle is small. When the wire passes through the dumbbell-shaped sliding wheel 3, it is concentrated in the middle position of the sliding wheel 3 under the action of gravity, thereby improving the accuracy of resistance value measurement.
[0044] In addition, the sliding wheel 3 is further provided with a rotating shaft, the sliding wheel 3 is rotatably connected to the rotating shaft, the rotating shaft is fixedly arranged on the two edges 12 of the wire conveying channel 11, the center line of the sliding wheel 3 coincides with the center line of the rotating shaft, the electrode 5 is in the shape of a ring and is sleeved on both ends of the sliding wheel 3, and the electrodes 5 at both ends are electrically connected to the elastic metal film 4.
[0045] It should be noted that the sliding wheel of the present embodiment includes a plurality of sliding wheels, for example, three or five, and each sliding wheel is arranged in parallel.
