Embodiment 1

[0030] In an embodiment of the present invention, a water sample collection device for environmental design of ancient villages includes:

[0031] The airbag floater 1 is connected with the sampling component through the adjustment mechanism, and the position limitation of the sampling mechanism is realized by the buoyancy of the airbag floater 1, thereby realizing the stability of the sampling process;

[0032] The shell 2 is used to accept the adjustment mechanism and the sampling component, and is in a sealed state;

[0033] The adjustment mechanism is used to adjust the distance of the sampling assembly relative to the air bag floater 1, thereby adjusting the water entry depth of the sampling assembly, and then realize the purpose of collecting water at the required depth. The adjustment mechanism includes a second motor 11, a second screw thread Sleeve 12 and second threaded rod 14, one end of the second threaded sleeve 12 is fixedly connected with the output shaft of the...

Embodiment 2

[0040] In order to make the technical solution of this application more perfect, this application also proposes another embodiment to describe the sampling assembly in detail, as follows:

[0041] The sampling components include:

[0042] More than one T-shaped piston cylinder 10 is discharged sequentially from top to bottom for water collection;

[0043] The piston 9 is arranged in the T-shaped piston cylinder 10 and is slidably connected with the inner wall of the T-shaped piston cylinder 10, and the piston 9 is connected with a driving mechanism for driving its reciprocating movement;

[0044] The collection port 4 communicates with the T-shaped piston cylinder 10 for the collection and entry of water;

[0045] The discharge port 5 communicates with the T-shaped piston cylinder 10 for the discharge of water.

[0046] The drive mechanism includes a first motor 6, a first threaded sleeve 7 and a first threaded rod 8, one end of the first threaded rod 8 is fixed on the pisto...

Abstract

The invention relates to a water sample collecting device for environmental design of an ancient village. The water sample collecting device comprises a gasbag type floating object connected to a sampling assembly through an adjusting mechanism, an outer shell for carrying the adjusting mechanism and the sampling assembly and in a sealed state and the adjusting mechanism. The adjusting mechanism includes a second motor, a second threaded sleeve and a second threaded rod, one end of the second threaded sleeve is fixedly connected to an output shaft of the second motor through a coupling, and the other end of the second threaded rod extends into a lifting cavity formed in the outer shell and is connected with the second threaded rod in a threaded mode. The upper end of the second threaded rod penetrates through the upper wall of the lifting cavity which is slidably connected with the upper end of the second threaded rod and is fixed to the gasbag type floating object. The water sample collecting device is novel in design, underwater positioning of the sampling assembly is performed by the gasbag type floating object, and the arranged adjusting mechanism can adjust the underwater penetration of the sampling assembly, so that water collection required at different depths is realized, the use is convenient, no excessive mechanical bracket supporting is required, and the structure issimple.

Description

technical field [0001] The invention relates to a sampling device, in particular to a water sample collection device used in the environmental design of ancient villages. Background technique [0002] Sampling is to select a representative sample from the target objects. Popular explanation: Take a few samples from a large number of items or materials. Random sampling: For the object that needs to be inspected and inspected, it is divided into several places at any part. Carry out the specified tests and inspection items with randomly selected samples, and make a ruling on the quality and technical indicators of the batch of inspections and inspection objects. Double sampling: When random sampling is carried out for testing and the test fails, double sampling must be carried out for the same batch of testing and testing objects, and then retesting. [0003] In the environmental design of ancient villages, water sample collection devices are needed. The existing collection...
