Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling, in particular to a bucket-type water sample collector. Background Art

[0002] According to the relevant standard requirements in the field of water quality sampling technology, when water can be directly drawn, appropriate containers such as buckets can be used for sampling; when sampling from places such as bridges, polyethylene buckets tied with ropes or sampling bottles with sinkers can be thrown into the water to draw water; when collecting water at a certain depth, upright or plexiglass water samplers can be used.

[0003] For water sampling in some dams, deep wells, box culverts and other areas, the reference bridge sampling method is mostly used, where a water sampler (sampling bottle) tied with a rope is put into the water to draw water.

[0004] However, since the water flow in the above-mentioned areas mostly flows along the wall or bottom, the water layer is relatively thin, which makes it impossible for the sampling container (sampling bottle) to fit effectively and the amount of water collected is extremely small; if a conventional upright or plexiglass water sampler is used, it cannot be opened and closed normally because the water layer is too shallow. This problem is particularly obvious when collecting water at the bottom of a deep well. Utility Model Content

[0005] The purpose of this utility model is to provide a bucket-type water sample collector to solve the problems existing in the above-mentioned related technologies. It adopts a bucket-shaped design to realize water sample collection by sticking to the surface of the water flow. Even when the water layer is thin, it can ensure the amount of water collected in a single water sample, thereby improving the water sample collection efficiency.

[0006] To achieve the above purpose, the present invention provides the following solutions:

[0007] The utility model provides a bucket-type water sample collector, comprising a water bucket and a sampling rope, wherein the water bucket is a triangular prism structure, a rectangular surface of the water bucket is open to form a water inlet, and a water outlet is provided on the water bucket at a position away from the water inlet; a counterweight assembly is provided in the water bucket, and the sampling rope is connected to the water bucket so that the water bucket can be lowered to a sampling area for water sample collection.

[0008] Preferably, the two triangular faces of the water intake hopper are both isosceles triangles, and the water inlet of the water intake hopper is located between the bases of the two triangular faces.

[0009] Preferably, the counterweight assembly includes a first counterweight rod and a second counterweight rod, the first counterweight rod is arranged at the water inlet of the water intake hopper, and the first counterweight rod is located in the middle of the water inlet and parallel to the bottom edge of the triangular surface of the water intake hopper; the second counterweight rod is arranged on the edge of the water intake hopper opposite to the water inlet.

[0010] Preferably, a fixing assembly is provided on the first counterweight rod, and the fixing assembly is used to be connected to the sampling rope.

[0011] Preferably, the fixing assembly is a fixing ring, and the fixing ring is fixed to the middle portion of the first counterweight rod.

[0012] Preferably, the axial direction of the fixing ring is arranged parallel to the second counterweight rod.

[0013] Preferably, the water outlet of the water intake hopper is arranged on any triangular surface of the water intake hopper and is located near the second counterweight rod.

[0014] Preferably, the outer side of the water outlet of the water intake hopper is connected to a water outlet pipe.

[0015] Compared with the related art, the utility model has achieved the following technical effects:

[0016] The bucket-type water sample collector provided by the utility model comprises a water bucket and a sampling rope. The water bucket is a triangular prism structure. When in use, for vertical water flow close to the wall, the water bucket is lowered to the downstream of the water flow through the sampling rope, and the center of gravity is adjusted by the counterweight component in the water bucket so that the water bucket is close to the wall. After standing for a few minutes, the sampling rope is quickly lifted to complete the water sample collection; for horizontal water flow close to the bottom, the water bucket is lowered through the sampling rope until it touches the bottom, and the center of gravity is adjusted by the counterweight component in the water bucket, and the sampling rope is slowly lowered so that the water bucket is tilted toward the upstream of the water flow until it is close to the bottom. After standing for a few minutes, the sampling rope is quickly lifted to complete the water sample collection.

[0017] This new model adopts a bucket-shaped design that can better fit the surface of the water flow for water sample collection, breaking away from the limitations of thin water layers and overcoming the difficulties of unclear bottom conditions and inconvenient operation in deep wells. It improves the efficiency of water sample collection and also increases the amount of water collected in a single sample, ensuring the representativeness of the sample. In addition, this new model can also replace traditional surface samplers and has strong compatibility with sampling from different water bodies. BRIEF DESCRIPTION OF THE DRAWINGS
