Description

Pickup test bench

Technical Field

The utility model belongs to the technical field of pickup appurtenance, especially, relate to a pickup testboard.

Background

Detectors, also called pickups, are devices that detect some useful information in a fluctuating signal, identifying the presence or change of waves, oscillations or signals. The detector is typically used to extract the information carried. The detectors are classified into envelope detectors and synchronous detectors. The output signal of the former corresponds to the envelope of the input signal, and is mainly used for demodulating the standard amplitude modulation signal. The latter is in fact an analog multiplier, and in order to obtain the demodulation action, it is necessary to add in addition an oscillating signal perfectly coincident with the carrier of the input signal. The synchronous detector is mainly used for demodulating a single-sideband amplitude-modulated signal or demodulating a vestigial sideband amplitude-modulated signal.

As is known, the detectors can not be separated in oil exploration, along with the update of scientific technology, the detectors are developed from the original 6-string 2-parallel detectors to the existing high-sensitivity single detector, namely, in years, the detectors are used as 6-string 2-parallel detector strings and are often used in grassland deserts to play a role in improving the field signal-to-noise ratio.

Therefore, in the daily use process, 30 ten thousand detector strings of 2 ten thousand and 5 thousand and individuals are tested, and the time spent on the detector strings and the test platform is quite long. The reason for this is that when the detector is inserted, the metal cone needs to be aligned with a small fixed ground cone hole on the platform and inserted into the subway cone hole, and after the test is finished, when the detector is taken down, the whole string of the detector is taken down, the metal inserted ground cone below the detector is often clamped in the hole, so that the detector is difficult to take down, and the detector can only be taken down from the test board one by one, so that the time spent is increased. However, if a large number of detector strings are tested in a fixed time, two minutes of delay is caused when each detector string is tested up and down, which increases labor cost. The three-component acquisition station also needs to ensure uniform verticality when obtaining qualified indexes of horizontal components and vertical components; moreover, as a large batch of tests are performed indoors, a good test platform is not available, and misjudgment is often caused. The device is convenient for field squadrons. In the field, if in the north, the ground width horizon is easy to be centrally inserted to the ground for testing.
