Problems solved by technology

[0003] (2) During the construction, the wire protection tube is easily crushed by machinery or trampled manually, causing the protection tube to break or be flattened.
(3) During the concrete vibrating process, it is easy to smash the protective tube or cause the joint to fall off
Due to the limitation of the pipe diameter, the size of the magnetic device is limited and the sensitivity is low.

Embodiment Construction

[0018] First, put the magnetic induction device (1) and the detection cable (2) into the wire protection tube until the magnetic induction device (1) reaches the blocking position; connect the end of the detection cable (2) with the trigger device (3); open the trigger device (3 ) and the power switch of the acousto-optic alarm device (5); the detection and positioning device (4) that can generate stable magnetism when moving along the direction of the wire protection tube on the floor or wall; when the magnetic induction device (1) senses the detection and positioning device ( 4) When the magnetic field is emitted, the acousto-optic alarm device (5) starts to send an audible-visual alarm signal, and writes down the boundary of its alarm area (about 100mm in diameter), and the center point of this area is exactly the accurate blockage position of the protective tube.

[0019] When detecting and positioning, it is necessary to ensure that the magnetic induction device (1) reache...

Abstract

A blocking site detection locator of the electric wire protective sleeve relates to a detection locating device of the blocking site of the electric wire protective sleeve. The detection locator is especially suitable for the detection and location of the blocking site of the electric wire protective sleeve in the building electrical construction which is laid in the concrete or wall. The detection locator comprises a magnetic induction device (1) and a detection cable which are inserted in the electric wire protective sleeve, a trigger device (3), a detection locating device (4) moving above the electric wire protective sleeve and a portable sound-and-light alarm (5); and the detection locator is convenient to operate, is economical and reasonable, and can realize accurate positioning.

Description

technical field [0001] The invention relates to a detection and positioning device for the blockage position of an electric wire protection tube, which is especially suitable for detection and positioning of the blockage position of the electric line protection tube hidden in the concrete floor or wall in building electrical construction. Background technique [0002] In the process of building electrical construction, it is a common phenomenon that the wire protection tube is blocked and the wire cannot pass through the tube. Concealed wire protection pipes laid in concrete floors or walls have a higher chance of clogging than exposed pipes. There are three main reasons for the blockage: (1) The joint of the protective pipe itself is a weak point, and the external force during the piping process can easily cause the joint to fall off. If there is a gap in the connection at the joint, the concrete mortar is easy to pour in. [0003] (2) During the construction, the wire pr...
