Embodiment Construction

[0011] The sealing sleeve of the cast bus duct joint of the present invention is made of metal materials. The width and height of the sealing sleeve are 5 to 25 mm larger than those of the bus duct body, and the length covers part of the pouring parts at both ends of the joint. The sealing sleeve is divided into two parts, the groove and the cover, in which there is a metal connecting strip on both sides of the inner side of the upper opening of the groove body, and each metal connecting strip is provided with no less than 2 threaded holes, and the cover plate is provided with threads for the metal connecting strip The position and quantity of the holes correspond to the countersunk head bolt holes, and the inner ends of the tank body and the cover plate are respectively equipped with sealing rubber strips. When the busway is installed, after the joints are connected, put the sealing sleeve tank body outside the joint, and then fasten the cover plate of the sealing sleeve with...

Abstract

The invention relates to a joint sealing sleeve for bus duct pouring. Metallic connecting bars (11) are arranged at two sides of the inner side of an upper opening of a sealing sleeve groove body (1) in the sealing sleeve; no less than two threaded holes (111) are formed in each metallic connecting bar (11); and cover plate bolt holes (22) having the number and positions corresponding to those of the threaded holes (111) are formed in a sealing sleeve cover plate (2). Groove body sealing rubber strips (12) are arranged at two edges of the inner side of the sealing sleeve groove body (1); cover plate sealing rubber strips (21) are arranged at the two ends of the sealing sleeve cover plate (2) respectively; a bus duct (5) is arranged inside the sealing sleeve groove body (1); and distances between the outer edges of the groove body sealing rubber strips (12) and the cover plate sealing rubber strips (21) and the two ends of the edges of the sealing sleeve groove body (1) and the sealing sleeve cover plate (2) are 3 to 10mm. According to the joint sealing sleeve provided by the invention, the sleeve can be installed at field conveniently; the sealing quality is reliable; checking can be carried out easily; and the protection level is IP68. Using the joint sealing sleeve, a problem of difficult pouring at the field of the bus duct pouring can be solved; and the hidden danger of connection of a prefabricated silicone rubber sealing bolt can be eliminated.

Description

technical field [0001] The invention relates to a low-voltage power transmission and distribution line busway main line system, and belongs to the technical field of electric power busway manufacturing. Background technique [0002] As a kind of high-current and low-voltage power distribution line in industrial and civil engineering construction, busway has been developed to solve the problem of waterproofing of busway as users and the environment increase the protection level of busway. However, the pouring of the busway joints needs to be done at the installation site. Due to the objective environmental conditions, it is difficult to pour the joints in some occasions. Among the existing foreign pouring busway products, there is a method of using prefabricated silicone rubber joints. Since the aluminum alloy shell of the joints is fastened by bolts during assembly, the silicone rubber cannot guarantee 100% waterproof and tightness under the condition of bolted connections. ...
