Inductive automatic bin-closing type transverse sampler

Abstract

An inductive automatic closing horizontal sampler of the present invention comprises a sampler body, and the sampler body includes a sampler bin, a sampler rod, a bin door and a door closing mechanism capable of closing the bin door under the action of pulling force. The door closing mechanism is connected with an electric push-pull rod driven by a cable, and the electric push-pull rod is connected with a control unit, and the control unit is connected with a wireless receiving controller, and the wireless receiving controller is matched with an independent infrared induction wireless transmitter. The beneficial effects of the present invention are: 1. The sampling position is accurate, the sampler automatically closes the warehouse door without manual intervention, the sampler moves up and down when there is no drag cable, and the sampling position is stable and accurate. 2. The sampling accuracy is high. During the test, the door must be moved in the sensing area for a period of time before the door is automatically closed, so that the sampling accuracy is guaranteed. 3. The labor intensity is reduced, and there is no need to manually pull the cable to close the warehouse door, which saves manpower.

Description

technical field [0001] The invention relates to an inductive type auto-closing horizontal sampler, which is applied to sand sample collection and water sample collection in the field of hydrology. Background technique [0002] At present, a horizontal sampler is generally used to collect water samples. When the sampler reaches the sampling position, stop for a while, then hold the sampler rod firmly with one hand, and yank the cable of the sampler with the other hand to open the door. Closed to obtain a water sample at the measuring point. It can be seen that when sampling, one hand holds the sampler rod, and the other hand also pulls the sampler cable, which is very troublesome, and the pulling force is very large, time-consuming and laborious, and the physical labor is relatively large. Because only one hand holds the sampler rod, the sampler is easily lost under the impact of the water flow and the sampler is lost, resulting in economic losses. Therefore, there is an ur...
