technical field

The utility model relates to the technical field of environmental protection and water resources monitoring, in particular to a self-filtering and sealing device of a deep self-filtering and sealing water fetcher.

Background technique

In order to ensure the needs of water body testing and monitoring in industries such as environmental protection, water conservancy, water resources, and urban domestic water, it is very important to quickly and accurately obtain water samples at specified locations and depths for accurate evaluation of water quality and pollution. In today's increasingly serious environment and water pollution, fast and accurate water sample filtration and selection technology is very necessary. However, at present, deep water sample collectors are scarce and immature, and the sampling location is not accurate. Due to the lack of sealing of the samples, the mixing of samples affects the quality of water samples, resulting in large deviations in on-site monitoring or test results. A self-filtering sealing device of a deep self-filtering sealing water fetcher and a method thereof are proposed, which will be widely used in engineering practice and scientific research.

Quickly and accurately obtaining high-quality water samples at a specified depth and without mixing is an important guarantee for the monitoring and evaluation of water quality in the environment, water conservancy, water resources and urban domestic water. In order to overcome the lack of deep water sample collection equipment and immature and outdated sampling methods, it is of great significance to study a high-quality deep water sample collection device that is easy to operate, accurate and fast, and the sample is sealed without mixing.

Self-filtering sealing device (referred to as device) of deep self-filtering sealing water dispenser

The self-filter sealing device is an indispensable and important functional part of the deep self-filter sealed water dispenser. It consists of a self-filter circular hollow gasket, a self-filter circular filter, a self-filter cover base, a self-filter seal Composed of cover positioning bracket, self-filtering sealing cover and self-filtering cover limiter;

Its location and connection relationship are:

The self-filtering hollow gasket is fixed on the through-wall water inlet sleeve of the bottom counterweight water inlet module with annular threads, from bottom to top, the self-filtering hollow gasket, the self-filtering circular filter, the self-filtering cover base and the self-filtering The filter sealing rings are connected sequentially; the left and right ends of the self-filter cover base are respectively fixed with a self-filter cover positioning bracket and a self-filter cover limit frame; the left end point of the self-filter seal cover is connected with the self-filter cover positioning bracket .

The working principle of this device:

During the descending process of the device, the self-filtering sealing cover is automatically opened under the buoyancy of the water, so that the deep self-filtering sealed water collector descends in the shape of a hollow tube, which not only reduces the resistance and buoyancy of the water, but also allows the water to pass through smoothly. Do not stay in the water storage tank;

Under the traction of the non-stretching scale pull rope, the deep self-filtering sealed water dispenser is lowered to the specified water intake depth, and it is left for about 5-10 seconds to completely fill the water storage tank;

Pull back the non-retractable scale pull rope to make the deep self-filtering sealed water dispenser rise;

During the rising process of the deep self-filtering sealing water dispenser, the self-filtering sealing cover of the self-filtering sealing device and the water-passing sealing cover of the water-passing sealing module are automatically closed under the resistance of the water, and the water sample is sealed in the water storage tank;

Continue to pull back the non-retractable scale pull rope until the device filled with water samples comes out of water;

Unscrew from the threaded connection between the upper hollow connection module and the water-through-wall water-through sleeve;

Pour out the water sample in the water storage tank from the upper end of the water sealing module, and put it into the pre-prepared sample bottle for later testing;

Screw the water-through-wall water-through sleeve back to the hollow connection module to prepare for the next water sample selection.

The utility model has the following advantages and positive effects:

①The self-filtering circular filter screen of the self-filtering sealing device initially automatically filters impurities, and uses the buoyancy and resistance of water to realize the automatic opening and closing of the self-filtering sealing cover;

② Even if there is a small amount of unfiltered impurities, the slightly protruding self-filtering sealing ring can still ensure the sealing effect;

③The self-filter sealing cover positioning bracket and the self-filter sealing cover limit frame not only ensure the normal opening and closing of the self-filter sealing cover, but also avoid the situation that the self-filter sealing cover cannot be returned due to excessive opening.

In a word, the utility model guarantees the effectiveness in all aspects of the device's water entry positioning, self-filtering, water sample collection and sealing, device recovery, etc., and can obtain high-quality water samples that have been preliminarily filtered by impurities, accurately positioned, and sealed without mixing; The hollow tubular shape can not only reduce the buoyancy and ensure smooth sinking, but also greatly reduce the disturbance to the surrounding water; the sealing ring and the self-opening and closing sealing cover ensure that the water sample is sealed and not mixed; each part of the whole device can be disassembled independently Assembly replacement, simple structure, easy to carry, durable, significant economic benefits, easy to popularize.
