Preferably, an internal thread is arranged in the through hole, and the insulating rod is connected with the through hole through a thread. The U-shaped clamping head is convenient to disassemble, and the stay bar is convenient to carry and transport.
Preferably, the opening directions of the two U-shaped clamping heads are the same, so that the hanging operation during installation is facilitated.
Preferably, the length of the moving rod is larger than the distance between the two side walls of the U-shaped chuck. The opening of the U-shaped clamping head can be completely closed after the movable rod extends out of the through hole, so that the drainage wire is fixed in the U-shaped clamping head and is not easy to fall off.
Preferably, the length of the insulating rod is 350-450 mm, the distance between two side walls of the U-shaped clamping head is 48-52 mm, and the distance from one side, close to the bottom surface of the U-shaped clamping head, of the moving rod to the bottom surface of the U-shaped clamping head is 30-35 mm. The insulating rod is within the length range, so that the adjacent drainage wires can be effectively prevented from contacting under the action of wind power and the like; the distance between the two side walls is within the range, so that the insulating drainage wire can be smoothly installed into the U-shaped chuck, and the drainage wire can be prevented from shaking greatly in the U-shaped chuck during use; the diameter of a commonly used drainage wire in China is generally 30mm, the distance between the moving rod and the bottom surface can ensure that the drainage wire is firmly clamped between the moving rod and the bottom surface of the U-shaped clamping head in the range, and the drainage wire is not easy to shake in the U-shaped clamping head under the action of wind power and the like during use, so that the increased fixation firmness is realized.
Preferably, the insulation rod and the U-shaped chuck are prepared by extruding and molding raw materials by an extruder, and the raw materials include the following components in parts by weight: 700-800 parts of waste rubber powder, 300-400 parts of waste polypropylene plastic powder, 100-200 parts of fly ash, 30-40 parts of 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane, 5-7 parts of sulfur powder, 6-18 parts of acrylic acid, 7-13 parts of azobisisobutyronitrile, 10-15 parts of a foaming agent, 5-10 parts of a coupling agent and 7-15 parts of a lubricating agent.

If the waste rubber powder and the waste polypropylene plastic powder are directly blended, the interface interaction of the waste rubber powder and the waste polypropylene plastic powder is weak, the compatibility is poor and the mechanical property is low, so in the invention, 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane and sulfur powder are added into the raw materials, in the process of melt blending, the 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane can initiate the in-situ chemical reaction between the waste rubber powder and the waste polypropylene plastic powder to generate the thermoplastic elastomer, the compatibility and the interface action of the two are obviously improved, and the generated thermoplastic elastomer has good elasticity and toughness, so that the manufactured insulating rod and the U-shaped chuck are not easy to break even falling from a high place.

The coupling agent is an organic matter with an amphoteric structure, and has more than one group acting with the surface of inorganic powder and more than one group having affinity with an organic polymer, wherein one part of the groups in the molecule can react with functional groups on the surface of the fly ash, and the other group can chemically react with or physically intertwine with the thermoplastic elastomer, so that two materials with very different properties are firmly combined, a molecular bridge with special functions is established between the fly ash and the thermoplastic elastomer, the fly ash is effectively and uniformly dispersed in the thermoplastic elastomer, and the insulating material with good comprehensive performance is successfully obtained. Meanwhile, acrylic acid and azobisisobutyronitrile are added into the raw materials, and during preparation, the acrylic acid can be initiated to perform a polymerization grafting reaction under the action of the initiator azobisisobutyronitrile, so that polyacrylic acid is grafted on the surface of the fly ash, and the surface of the fly ash is modified together with the coupling agent, so that the fly ash can be better dispersed in a matrix, and the mechanical properties of the insulating rod and the U-shaped chuck are improved.
The invention also adds the foaming agent, so that the manufactured insulating material is a foaming material, the weight of the stay bar is reduced under the condition of ensuring the mechanical properties of the insulating bar and the U-shaped chuck, and the stay bar is convenient to carry.
Preferably, the foaming agent is a mixture of 1: sodium lauryl sulfate and azodicarbonamide of (1-2). The foaming temperatures of the lauryl sodium sulfate and the azodicarbonamide are different, the lauryl sodium sulfate can be foamed below 100 ℃, the azodicarbonamide can be foamed at about 160 ℃, two foaming agents with different foaming temperatures are used for foaming twice at different temperatures, and compared with the method of only foaming once, the method can effectively reduce the density of the insulating rod and the U-shaped chuck and obviously improve the dimensional stability.
Preferably, the lubricant is octadecanoic acid and the coupling agent is a silane coupling agent. The octadecanoic acid is used as the lubricant, so that the material has good demolding performance, the processing of the product is facilitated, and the waste of the material is reduced; because the main component in the fly ash is SiO2The silane coupling agent can be used for effectively modifying the surface of the fly ash, and the compatibility between the fly ash and the thermoplastic elastomer matrix is improved.
Preferably, the extrusion temperature of the extruder is 160-270 ℃. In the temperature range, the components can be ensured to be fully melted and reacted, and the two foaming agents can be smoothly foamed twice.
Therefore, the invention has the following beneficial effects:
