Wireless transmitter of conduit blockage detector

Abstract

The invention discloses a wireless transmitter of a conduit blockage detector. The wireless transmitter comprises a shell. A power source, a signal transmission coil, a high frequency signal generator and a switch are disposed in the shell. The wireless transmitter is characterized by further comprising an elastic magnetic mandrel. The signal transmission coil is wound at one end of the elastic magnetic mandrel. The other end of the elastic magnetic mandrel extends out of the shell to be connected with a threader. The wireless transmitter is simple in structure, low in power consumption, high in signal strength and small in size, has few components and is capable of smoothly passing bends of pipes.

Description

technical field [0001] The invention relates to a wireless transmitting head for a threading pipe blockage detector used in building electric wire ducts. Background technique [0002] In the process of building construction, it often happens that the pre-laid PVC pipes are blocked by sand, cement, stones, etc. and cannot be threaded smoothly. , Seriously even delay the construction period. In order to solve the above problems, people have manufactured a pipeline blockage detector, which includes a signal transmitter and a signal receiver. The signal transmitter can transmit wireless signals, and the signal transmitter is sent into the pipeline to be tested through the transmission line until The transmitter encounters a blockage until it can no longer move forward, then turn on the signal receiver and detect along the pipeline. When the receiver emits the loudest sound, it is the blockage, and the repair can be performed by marking the pipeline. [0003] The wireless tran...

Problems solved by technology

[0003] The wireless transmitting head of the pipe blockage measuring device in the prior art includes a housing, and a circuit board is arranged in the housing, and a power supply component (2 button batteries), a signal transmitting coil, a high-frequency signal generator and a switch are arranged on the circuit board , the end of the above-mentioned circuit board protruding from the shell is fixed with a threader through screws. Since the circuit board and the threader are rigidly connected, in addition, too many components make the emitter too large. When reaching a pipeline with a corner, it is not easy to pass through, and it is easy to cause the illusion of pipeline blockage, which cannot complete the detection of the detector and reduce the test accuracy of the detector
