Description

Technical Field

[0001] The utility model belongs to the technical field of electric wire and cable sealing, and particularly relates to a quick-sealing device for electric wire and cable heads. Background Art

[0002] Sealing wires and cables is crucial for power transmission. If cable cutouts are not properly sealed during storage or transportation, foreign matter such as water and dust can enter the cable through the cutouts, causing moisture and corrosion inside the cable, which in turn damages the insulation. This damage can lead to cable aging and short circuits, which can easily cause serious accidents such as fires and explosions. Furthermore, cable line failures can cause power line outages, disrupting production, causing significant economic losses to the power grid, and even posing a safety threat to workers and the production environment.

[0003] Currently, the sealing of wires and cables mainly relies on manual operation, with commonly used tools including hot air guns and heat shrink tubing. However, there are several problems with this traditional method:

[0004] 1. Low operating efficiency: Workers need to hold a hot air gun to perform heating and sealing operations. The hot air is easy to dissipate and the heat shrink tubing cannot be heated evenly, resulting in a long sealing time and low efficiency.

[0005] 2. High safety risk: Since the hot air gun is used in a handheld operation, the concentrated hot air from the hot air gun is easily over-concentrated in a certain location, which may cause burns to the workers or damage the external insulation layer of the wires and cables, posing a major safety hazard.

[0006] 3. Unstable sealing quality: The sealing effect depends largely on the skills and experience of the operator. Improper operation may lead to loose sealing, easy damage to the inside of the cable or premature aging of the insulation.

[0007] Therefore, the manual plugging method in the existing technology has defects such as complex operation, low efficiency, poor safety and unstable quality. There is an urgent need for a tool that can simplify the operation process, improve efficiency and ensure the plugging quality. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a wire and cable head quick sealing device which can realize uniform diffusion of hot air, avoid local overheating, improve sealing efficiency and quality, has good adaptability, is convenient to operate and is safe and reliable.

[0009] The technical solution of the utility model is: a wire and cable head quick sealing device, comprising: a hot air gun, a cavity upper cover, a knob chuck, a fixing ring buckle, a cavity lower cover, a connecting ring buckle, an air expansion cover and a heat shrink sleeve, the cavity upper cover and the cavity lower cover are connected to form a hollow cylindrical cavity structure, one end of the hollow cylindrical cavity structure is fixedly connected to the air outlet of the hot air gun through a fixing ring buckle and a connecting ring buckle, the other end of the hollow cylindrical cavity structure is provided with a knob chuck, the The knob chuck fixes the cable at the air outlet position of the hollow cylindrical cavity structure, and the fixing ring buckle covers the air outlet of the air expansion cover and the hot air gun respectively, fixing the air expansion cover to the air outlet of the hot air gun, and the fixing ring buckle and the air expansion cover are nested on the inner side of the cavity lower cover, and the connecting ring buckle covers the fixing ring buckle and the hollow cylindrical cavity structure respectively, fixing the hollow cylindrical cavity structure to the air outlet of the hot air gun, and the heat shrink sleeve is located in the hollow cylindrical cavity structure and is sleeved with the cable head.

[0010] Furthermore, the cavity upper cover and the cavity lower cover are fixedly connected by screws.

[0011] Furthermore, the knob chuck is fixed between the cavity upper cover and the cavity lower cover by screws.

[0012] Furthermore, an elastic sealing ring is provided on the knob chuck.

[0013] Furthermore, the fixing ring buckle is a hoop structure and is fixedly connected to the air diffuser cover via a latch, and the connecting ring buckle is a hoop structure.

[0014] Furthermore, the air diffuser cover is a trumpet-shaped or bowl-shaped structure, and the opening angle of the air diffuser cover is 35 degrees.

[0015] Furthermore, a protective heat-insulating pad is provided at the connection between the hot air gun and the hollow cylindrical cavity structure.

[0016] Furthermore, the inner sides of the cavity upper cover and the cavity lower cover are covered with a high temperature resistant coating.

[0017] Beneficial effects of the utility model:

[0018] 1. Significantly improve operating efficiency:

[0019] The traditional manual plugging method takes a long time to plug due to the escape of hot air and uneven heating. However, the utility model uses the design of a trumpet-shaped or bowl-shaped air diffuser to evenly diffuse the hot air in the cavity, so that the heat shrink sleeve is evenly heated, which greatly shortens the plugging time. According to actual tests, the use of this tool can reduce the plugging time by about 30%-40%, greatly improving work efficiency.

[0020] 2. Improve work safety:

[0021] The traditional handheld hot air gun is easy to cause damage to the cable outer insulation due to the hot air concentrated in a single place, and even cause burns to the operator. The diffuse hot air design of the utility model avoids the safety hazards of concentrated hot air, significantly reduces the incidence of burn accidents, and is safer and more reliable to operate.

[0022] 3. Stable sealing quality:

[0023] The utility model can make the hot air diffuse evenly, and the heat shrink sleeve is heated more evenly, ensuring that it can shrink evenly at the appropriate temperature, and the sealing effect is consistent and reliable, avoiding the loose sealing or sealing failure caused by local overheating in traditional methods. According to actual tests, the sealing quality qualification rate has increased by 20%-30%, effectively reducing the frequency and cost of subsequent maintenance.

[0024] 4. Save material costs:

[0025] The utility model can control the uniform shrinkage of the heat shrink sleeve, avoid material damage caused by uneven heating or improper operation, and thus reduce material waste. In actual tests, material loss was reduced by 15%-25%, saving operating costs for power companies;

[0026] 5. Strong applicability:

[0027] The fixing ring buckle and connecting ring buckle of the utility model adopt an expansion quick-release structure, which is suitable for most hot air guns on the market and has good versatility. At the same time, the quick sealing device can adapt to the sealing operations of cable heads of different specifications, has a wide range of applications, and meets the sealing needs in different scenarios in the power industry.
