Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, in an embodiment of the present invention, a waterproof wire sleeve for communication engineering includes: a connection cable 1; a hollow pipe 2; a heat shrinkable tube 3; a heat-preserving chamber 4; a black film 5; the hollow tube 2 is of a circular wall structure, the hollow tube 2 is of a hollow shell structure, a hollow cavity is arranged in the hollow tube 2 to form a heat preservation cavity 4, two sections of connected connecting cables 1 are embedded in the hollow tube 2, the joint of the two sections of connected connecting cables 1 is located in the middle of the hollow tube 2, the sealing positions of the two ends of the hollow tube 2 are respectively provided with a heat shrinkable tube 3 in a heat shrinkage mode, the heat shrinkable tubes 3 tightly cover the port of the hollow tube 2 and the connecting cables 1, the heat shrinkable tubes 3 tightly seal the gap between the port of the connecting cables 1 and the gap between the connecting cables 1, and a cylindrical black film concentric with the hollow tube 2 is arranged between the hollow tube 2 and the two sections of connected.

The heat-preserving cavity 4 is vacuumized.

The hollow pipe 2 is a glass hollow pipe or a transparent PC hollow pipe.

The black film 5 is a coating on the inner wall of the hollow tube 2 or a black sticker wrapped on the outer layer of the connecting cable.

The heat shrinkable tube 3 is a black rubber-containing heat shrinkable sleeve made of polyolefin material.

The connection cable 1 may be a metal cable or an optical cable.

The utility model discloses a theory of operation is: when the heat shrinkable tube is used, the hollow tube 2 and the two sections of heat shrinkable tubes 3 are firstly embedded on the same connecting cable 1, then the two sections of connecting cables 1 to be connected are connected, then the hollow tube 2 is slid, the joint of the two sections of connecting cables 1 to be connected is positioned in the middle of the hollow tube 2, then the two sections of heat shrinkable tubes 3 are respectively moved to cover the sealing parts at the two ends of the hollow tube 2, then the two sections of heat shrinkable tubes 3 are heated by a heating device, so that the two sections of heat shrinkable tubes 3 are shrunk and the heat shrinkable tubes 3 are tightly covered on the port of the hollow tube 2 and the connecting cable 1, when raining, the two sections of heat shrinkable tubes 3 are tightly covered on the port of the hollow tube 2 and the connecting cable 1, so that the heat shrinkable tubes 3 can block a large amount of water and prevent the water from entering the hollow tube 2, when the rainfall is larger, if some water is carelessly infiltrated in the interior, the water can interfere or corrode the joints of the two connecting cables 1, so that signals transmitted by the connecting cables 1 are damaged or interrupted, when raining or after raining, daily sunlight passes through the first layer of glass of the hollow tube 2 and irradiates the black film 5 of the second layer of glass, the black film 5 absorbs the heat of sunlight energy due to the heat absorption performance and the light absorption performance of the black film, the heat insulation is realized between the two layers of glass of the hollow tube 2, the heat transfer is greatly reduced (the radiation heat transfer still exists, but the heat transfer and the heat convection are avoided), most of heat can only be transferred to the water in the hollow tube 2, the water in the glass tube is heated, the heated water is heated and evaporated, and the purpose of removing the water permeating at the joints of the connecting cables 1 is achieved.
