Embodiment Construction

[0019] The novel adjustable electric wire of the present invention comprises an inner core, an insulating layer, a waterproof film and a connection interface. Among them, the waterproof film wraps the insulating layer, the insulating layer wraps the inner core, and the connection interface is used to connect the various wires. There are two types of cross-sections for the inner core, one is a circular cross-section and the other is a flat cross-section. The wire adopts segmented design, so the effect of adjusting the length can be achieved. The standard lengths include 1m, 2m, 5m, 10m, 20m and 50m, and the specific length can be selected according to the actual site requirements.

[0020] The wire is designed with an outsourcing waterproof film. On the one hand, it can play a good waterproof effect to prolong the service life of the wire. On the other hand, the easy replacement of the film can meet the requirements of field tests to a greater extent.

[0021] The insulation ...

Abstract

The invention discloses a length-fixed antenna with special antenna adaptor device to solve the problem that the prior normal antenna has difficulties in meeting different requirements due to complex on-site test environment and working conditions of a structure during the field test of various engineering structures. According to the actual conditions of field test environments and the characteristics of different structures, the antenna adopts a waterproof film design and has a length adjusting function and a super-high pressure-resistance and waterproof function. Meanwhile, according to design, the antenna is available in circular and flat cross sections so as to meet the requirements on antennae of specific test environments. Obviously, the adjustable antenna for testing engineering structures can well meet the requirements of complex field test environments on the antennae, improve the safety and convenience of on-site test operations, and guarantee the smooth completion of the on-site test operations.

Description

technical field [0001] The invention relates to a special-shaped electric wire transfer device, which is especially suitable for connecting a power source and a test instrument when testing various engineering structures in the field. Background technique [0002] In order to accurately evaluate the construction quality of the engineering structure, grasp the stress state of the structure, evaluate the safety of the structure, and predict its remaining life, etc., it is necessary to go to the site where the engineering structure is located for testing work to provide reliable measured data as the main in accordance with. However, unlike the tests in the laboratory, the external environment and conditions of the on-site test work are very complicated, so it is more difficult. In the process of testing structures, after installing various testing instruments, it is usually necessary to connect the corresponding power supply, data acquisition, analysis and storage devices with...
