Problems solved by technology

[0004] However, the above-mentioned device determines the water entry depth of the sampling bottle by the depth of the steel wire rope inserted into the water. Since the steel wire rope is not necessarily in a vertical state, it cannot accurately determine the depth of the sampling bottle.
In addition, it is extremely inconvenient to open the bottle cap by pulling the wire rope

Embodiment Construction

[0018] The present invention will be described in further detail below by means of specific embodiments:

[0019] The reference signs in the accompanying drawings of the description include: sampling bottle body 10, sampling chamber 11, air chamber 12, high pressure chamber 13, rubber film 21, fixing ring 22, fixing ring body 23, drawstring 31, air bag 32, exhaust valve 41. Intake valve 42, communication channel 43, first one-way valve 44, float valve 45, second float 46, first float 47, plug 48, weight 51.

[0020] The embodiment is basically as figure 1 Shown:

[0021] The easy-to-control sampling bottle of this embodiment includes a sampling bottle body 10, a stay cord 31 connected to the sampling bottle body 10, and a weight 51 fixed at the lower end of the sampling bottle body 10, and the stay cord 31 is used to pull the sampling bottle body 10 back. And the weight 51 can make the sampling bottle body 10 sink in water. The upper end of the sampling bottle body 10 is pr...

Abstract

The invention discloses an easily controlled sampling bottle, and relates to the technical field of environment monitoring and sampling devices. The easily controlled sampling bottle comprises a sampling bottle body, a stay rope and a weight, an opening is arranged at the upper end of the sampling bottle body, the opening is plugged by an elastic rubber film, a separator plate is arranged in the inner chamber of the sampling bottle body and divides the inner chamber of the sampling bottle body into an air chamber positioned at the upper portion of the sampling bottle body and a sampling chamber positioned at the lower portion of the sampling bottle body; a water inlet valve for communicating the external of the sampling bottle body with the sampling chamber after conduction is arranged on the separator plate, the water inlet valve comprises a plugging head, and the upper portion of the plugging head is connected with the middle portion of the rubber film; and the sampling bottle body is provided with a communicating channel for communicating the air chamber with the sampling chamber, and a first non-return valve is conducted when a fluid entering the air chamber from the sampling chamber exists in the communicating channel. The water inlet valve is automatically opened after the sampling bottle body reaches a preset depth, and the water inlet valve is automatically closed after sampling is finished, so the water depth is accurately controlled.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring sampling equipment, in particular to an easy-to-control sampling bottle. Background technique [0002] In environmental water quality monitoring, the requirements for sampling water quality bacteria items are: 1. Sample bottles must be sterilized, glass bottles or plastic bottles can be used, and wide-mouth glass bottles are generally used, because high-temperature sterilization methods are usually used in the field of environmental monitoring ; 2. At the monitoring site, it is necessary to prevent the bottle cap and the inside of the bottle from being contaminated by bacteria; 3. The sampling bottle cannot be cleaned with on-site water samples. The first and third requirements above are easy to meet, but in order to meet the second requirement, the common practice is to hold the sampling bottle and open the bottle cap under the water surface. However, when the water depth exceed...
