Embodiment 2

[0037] This embodiment provides a kind of deicing agent, and described deicing agent comprises the composition of following percentage by weight: ethylene glycol 35%-47%, propylene glycol 12%-20%, potassium acetate 10%-15%, nitric acid Ammonium 5.2%-6.5%, potassium dihydrogen phosphate 6%-8.5%, deionized water 18%-20%.

[0038] The process concrete steps of this deicing agent are as follows:

[0039] 1) Take 10%-15% by weight of potassium acetate, 5.2%-6.5% of ammonium nitrate, 6%-8.5% of potassium dihydrogen phosphate, and add 18%-20% of deionized water, set In a magnetic stirrer, stir at 20°C-25°C for 20min-30min;

[0040] 2) Add 35%-47% ethylene glycol and 12%-20% propylene glycol to the mixture obtained in step 1), and stir for 10min-20min at 20°C-25°C;

[0041] 3) Put the mixture obtained in step 2) into an ultrasonic oscillator, vibrate at 20°C-25°C for 2h-3h, let it stand for 3h, and then discharge to obtain the product.

Embodiment 3

[0043] The cross-arm support device with ice-melting function provided in this embodiment is an improvement on the basis of Embodiment 1: refer to Figure 5 , Anti-slip lines 13 are provided on the inner wall of the cylinder 1 and the spring sheet 8 . refer to Image 6 , the end of the cylindrical tube 1 is provided with a boss 25, the side of the cylindrical tube 1 is provided with several exhaust holes 15, the cylindrical tube 1 is provided with a hoop 14, and the hoop 14 is entangled by the fourth bolt .

[0044] Wherein, the anti-slip lines 13 increase the friction between the electric pole and the installation is more firm. The boss 25 can be set in a conical or hemispherical shape, which can avoid water accumulation at the end of the cylinder 1 . The exhaust hole 15 is beneficial to the air circulation in the cylinder 1 . The hoop 14 is engaged by the fourth bolt to strengthen the fixing of the cylindrical tube 1 and make it more stable.

Abstract

The invention provides a cross arm supporting device with an ice melting function, and belongs to the technical field of power transmission lines. The cross arm supporting device with the ice melting function comprises a supporting mechanism and an ice melting mechanism; the supporting mechanism comprises a cylinder and a plurality of cross arms, wherein one end of the cylinder is sealed; a plurality of grooves are vertically formed in the side face of the cylinder, a plurality of limiting blocks are arranged on each of the two sides of each groove, the limiting blocks are connected with telescopic rods through second bolts, clamping grooves are formed in the ends of the telescopic rods, and spring pieces are arranged on the upper portion of the inner side of the cylinder in an enclosed mode; the ice melting mechanism comprises a liquid storing cylinder and an annular spraying pipe, wherein the liquid storing cylinder is arranged on the lower portion of the cylinder, and the annular spraying pipe is arranged on an electric pole in a sleeving mode; the liquid storing cylinder is connected with the spraying pipe through conveying pipes, and valves are arranged on the conveying pipes; and a plurality of spraying holes are evenly formed in one side, close to the electric pole, of the spraying pipe, a liquid inlet pipe is arranged on the liquid storing cylinder, a control valve is arranged on the liquid inlet pipe, and an ice melting agent is stored in the liquid storing cylinder. By adoption of the cross arm supporting device with the ice melting function, a cross arm can be firmly connected with the electric pole, ice covering on the electric pole can be melted, therefore the cross arm supporting device with the ice melting function is convenient and reliable, and high in adaptability.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a cross-arm support device with an ice-melting function. Background technique [0002] With the rapid development of the electric power industry, the safety of the line has become inseparable from our daily life and work. If the power supply is interrupted, it will not only affect the normal power consumption of users, but also bring property and economic losses to the power supply department. The safety of the line and ensuring its normal operation have become one of the key directions of electric power work. On the power transmission line, the pole and its upper support frame are generally used as the support carrier of the transmission line. The cross-arm is the main carrier for carrying and supporting connectors. It is mainly used to support insulators, wires and power distribution equipment on the column. It is also the main supporting platform for carryin...
