Detailed Description

For the purpose of explaining the technical content and the structural features of the water sample collecting device with fixed depth of the present invention in detail, the following description is further made with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1, the utility model discloses water sample collection system of fixed degree of depth, including collection bucket 1, depthkeeping pole sleeve 2, depthkeeping pole 3 down, go up depthkeeping pole 4, removable cover 5, apron baffle 6, baffle stand 7, apron stay cord 8, the hole of permeating water 9 and intake 10. The collection bucket 1 is divided in the first half and is had the hole of permeating water 9, is favorable to the free exchange of water sample and the device outer water in collection bucket 1, collection bucket 1 top be provided with removable cover 5, axial direction is provided with apron baffle 6 and baffle stand 7, the baffle stand play fixedly apron baffle 6's effect. The movable cover plate 5 is connected with a cover plate pull rope 8. The depth setting rod sleeve 2 is fixed on one side of the collecting barrel 1, the lower depth setting rod 3 and the upper depth setting rod 4 are arranged in the depth setting rod sleeve 2, the depth setting rod is of a multi-section sleeve type structure, the depth setting rod with the required length is drawn out from the depth setting rod sleeve according to the sampling depth requirement, and the depth setting rod is used for calibrating the distance between a sampling point position and the water surface and the bottom of a river bed, so that the purpose that the sampling device can be accurately placed at the fixed depth sampling point position is achieved.

The bottom of collection bucket 1 sets up intake 10, and intake 10 department sets up the valve, and in whole water sample collection process, the valve is in the closed condition, finishes when whole water sample collection, takes out the water sample of gathering by opening intake valve and bottles the storage.

The movable cover plates 5 are arranged to be two and are respectively positioned at the left side and the right side of the cover plate baffle 6, and the openings at the top of the collecting barrels can be closed after the movable cover plates 5 and the cover plate baffle 6 are combined.

The utility model discloses specific water sample collection step is as follows: firstly, the upper depth fixing rod 4 or the lower depth fixing rod 3 is drawn out from the depth fixing rod sleeve 2, if a water sample with a fixed depth below the water surface needs to be collected, the upper depth fixing rod 4 is drawn out, if a water sample with a fixed distance to the bottom of a river bed needs to be collected, the lower depth fixing rod 3 is drawn out, and the drawing length is determined according to the actual depth requirement of sampling. For example, a water sample at 0.5m below the water surface needs to be collected, the upper depth fixing rod 4 is pulled out to enable the length of the upper depth fixing rod to be close to 0.5m (the starting point of the marking distance of the depth fixing rod 4 is the central position of the collection barrel 1), then the whole collection device is placed into the water body until the upper depth fixing rod just submerges the whole position, at the moment, the point position of the collection barrel 1 is 0.5m below the water surface, and the collection depth of the water sample can be fixed through the method. When gathering 1 when being located the required degree of depth position of collection point location, the water can flow into in the collection bucket 1 naturally to, gather the water inside and outside 1 of bucket and can carry out free exchange through gathering the bucket hole 9 of permeating water, guarantee the uniformity of gathering 1 inside and outside quality of water. Then, mention whole water sample collection system through apron stay cord 8, apron 5 will be closed at 6 departments of apron baffle of pulling force downstream upward movement, and at this moment, the water sample in the collection bucket 1 is airtight through the apron baffle, prevents to lift the in-process at water sample collection system and mix with the device external water body. When the whole water sample collecting device is used for lifting out water, water on the upper part of the collecting barrel is discharged out of the collecting barrel 1 through the water permeable holes, and the rest part on the lower part of the collecting barrel 1 is the collected water sample. And finishing the water sample collection step. In the process of lifting the collecting device, a water sample in the collecting barrel 1 is sealed through the cover plate baffle plate, so that the water sample is prevented from being mixed with water outside the device in the lifting process of the water sample collecting device, the water sample on the upper part of the collecting barrel 1 with the water permeable holes 9 possibly has partial mixing problem, and the water sample is discharged out of the collecting barrel 1 through the natural outflow of the dead weight of the water after being lifted out of the water surface, so that the consistency of the finally collected water sample and the water quality of the water sample with the required collecting depth is ensured.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the present invention is not limited by the appended claims.
