Description
Technical field：
The present invention relates to the technical fields of detection auxiliary device, are specifically related to a kind of water sampling machine for drone
Structure.
Background technology：
Environmental monitoring is to track ring by the detection of the content, discharge capacity of various substances influential on the mankind and environment
The variation of border quality determines environmental quality level, provides basis for work such as environmental management, pollution controls and ensures.Simply
It says, understands ambient level, carry out environmental monitoring, be the premise for carrying out all environmental works.Environmental monitoring generally includes background tune
It looks into, determine the processes such as scheme, Optimizing, spot sampling, sample transport, experimental analysis, data collection, analysis integrated.Scene
Sampling be environmental monitoring detection in important composition, as Environment of Reservoirs monitor in, data source both from acquisition water sample, and
Each point of the water sample of acquisition from reservoir, existing employing mode are using personnel's acquisition manually by ship, and labor intensity is larger,
Especially for some seasick staff, it is larger that difficulty is acquired manually.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found, one kind is new structural to be used for
The water sampling mechanism of drone makes it with more the utility value in industry.
Invention content：
The purpose of the present invention aims to solve the problem that problem of the existing technology, provide it is a kind of use remote control type, facilitate using with
The water sampling mechanism for drone of reservoir each point water sampling.
The present invention relates to a kind of water sampling mechanism for drone, including drone, it is equipped in the drone
Sampling apparatus, the sampling apparatus include mounting disc and the vertical sampling pipe that is fixed on the mounting disc bottom surface, the peace
Sabot is fixedly mounted in drone, and the mounting disc bottom surface of the sampling tube hub is fixed with vertical fulcrum, on the fulcrum
Form that equally distributed demarcation strip, the side of the demarcation strip are close to and are fixed on sampling pipe in a ring around branch shaft centre line
On inner wall, sampling pipe is separated into the sampling cavity of several tapers by demarcation strip, each on the corresponding sampling tube wall of the sampling cavity
Water inlet is formed, the sampling pipe upper sleeve outside the water inlet has rotatory sealing set, and the upper end of sampling pipe, which forms, to be tightly attached to
The outer wall upper sleeve of flange on mounting disc bottom surface, sampling pipe is fixed with stop collar, the upper and lower end face point of the rotatory sealing set
It not being resisted against on the flange and stop collar, rotatory sealing puts on the water inlet notch for forming and coordinating with the water inlet of sampling pipe,
The water inlet notch is distributed in the downside of drone hull bottom, and first is formed on the inner wall of the rotatory sealing set above notch of intaking
Arc groove sets in first arc groove and is fixed with the first inductor, formed in the sampling pipe outer wall above water inlet with
Matched second arc groove of first arc groove, sets in second arc groove to be fixed with and coordinates with first inductor
Second inductor, the rotatory sealing above notch of intaking put on the gear ring for forming annular, and gear ring engagement is connected with gear,
The shaft of the gear connection driving motor, the driving motor are connected with the first inductor and the second inductor；

By above-mentioned technical proposal, in the use of the present invention, remote control acquisition water sample is realized by drone, when not sampling,
The water inlet notch of rotatory sealing set is on sampling tube wall positioned at water inlet between, when sampling, when one sample point of arrival, drives
Motor driven gear rotates, and gear drives the ring gear against rotation being engaged with, gear ring to drive rotatory sealing set rotation so that intake chamber
The water inlet of mouth and one of sampling cavity coincides, and at the same time, the first arc groove is gone on the second arc groove, the first induction
Device and the second inductor, which cooperate, to be incuded, and sends a signal to driving motor and driving motor is stalled, then water is just close from rotating
The water inlet notch of big envelope enters in one of sampling cavity, and after acquisition, driving motor drives rotatory sealing set rotation real again
Existing rotatory sealing set sealing water inlet, when reaching another sampled point, driving motor drive again rotatory sealing set rotation make into
Sink mouth and the water inlet of another sampling cavity coincide, while the first inductor and the second inductor mutual induction to drive
Motor stalls, and to which another sampling cavity is acquired water sample, repeats the above steps, thus the sampling cavity in sampling pipe can be successively
Acquire the water sample of different sampled points.Make the sealing cover on plug corresponding with the sampling cavity to be sampled by rotating plug, comes
The water sample in different sampling cavities is individually taken, specifically, since the shrinkage pool in the bulb plunger and sampling pipe on plug corresponds,
Therefore when rotating plug, bulb plunger leaves current shrinkage pool and is embedded in next shrinkage pool and sends out " click click " sound, listens
Plug is represented when to " click click " sound to rotate in place, when sealing cover is gone under destination sample chamber, stop operating plug, then lifts
The sealing cover on plug is opened to take water sample away.
Through the above scheme, the water sampling mechanism for drone of the invention can realize remote control acquisition water sample, be not necessarily to
Staff acquires manually, easy to use, and suitable for the collecting work of lake each point water sample, is brought for collection in worksite water sample
It is convenient.
As a preference of the above scheme, there are six the demarcation strip in the sampling pipe and sampling cavity are all provided with, sampling pipe
On water inlet and shrinkage pool be respectively equipped with six, sampling cavity and water inlet are uniformly distributed rotating around fulcrum is arc-shaped, plug in circle
Shape, the bulb plunger on shrinkage pool and plug are uniformly distributed in a ring rotating around the center of plug, the sampling pipe pipe below stop collar
The waterproof label of corresponding each sampling cavity is posted on wall, the waterproof Labels Were Marked with numeral mark, and waterproof label is around sampling pipe
Center be uniformly distributed in a ring.By said program, the setting of waterproof label contributes to sample collector to understand in each sampling cavity
Water sample ownership, to can effectively be distinguished when taking water sample away.
As a preference of the above scheme, the water inlet is located in the middle part of the corresponding sampling tube wall of each sampling cavity,
When not sampled, the sampling tube wall middle part of the water inlet notch of rotatory sealing set between adjacent water inlet.
As a preference of the above scheme, the water inlet and water inlet notch are rectangle, water inlet and water inlet notch
Height it is equal, the width of notch of intaking is more than the width of water inlet.
As a preference of the above scheme, the sampling tube wall of the water inlet upper and lower sides is equipped with sealing ring, described
Sealing ring is pressed against on the inner wall of rotatory sealing set, and the sealing ring of upside is between the second arc groove and water inlet.
As a preference of the above scheme, the shaft of the driving motor is fixedly connected with the gear across mounting disc,
Driving motor is fixed on the top surface of mounting disc.
