Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water sample collection, in particular to a sample collection device for environmental monitoring. Background Art
[0002] Environmental monitoring is an important means to ensure environmental quality, and the collection of water samples is a basic step in environmental water quality monitoring. Traditional water sample collection devices have many problems, such as low collection efficiency, water sample quality is easily contaminated, complex operation and high physical exertion, which seriously restrict the accuracy and efficiency of environmental monitoring.
[0003] In the process of collecting water samples, traditional methods usually require the operator to shake the rope vigorously or take other measures to tilt the collection tube so that the water sample can enter the collection tube smoothly. This operation method not only requires the operator to have a certain amount of physical strength and skills, but also often causes water samples to splash out due to improper operation, which seriously affects the collection effect of water samples. In addition, because traditional collection methods make it difficult to seal water samples during or immediately after sampling, water samples are easily affected by the external environment, such as the intrusion of pollutants such as dust and microorganisms in the air, which further increases the risk of water sample contamination and affects the accuracy of subsequent water quality monitoring.

[0012] (III) Beneficial effects
[0013] Compared with the prior art, the utility model provides a sample collection device for environmental monitoring, which has the following beneficial effects:
[0014] The utility model provides a threaded rod to drive the piston plate and the sealing cover to move upward at the same time, so that the device can also seal the sample synchronously after the sampling is completed. The sampling process remains in a stable state, reducing the possibility of splashing of water samples. The water sample is sealed immediately during or after the sampling process, effectively preventing the water sample from being contaminated. This not only improves the collection efficiency of the water sample, but also ensures the quality of the water sample, providing reliable data support for subsequent environmental monitoring work.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-3 The utility model provides a technical solution for a sample collection device for environmental monitoring:
[0021] according to Figure 1-3As shown, a sample collection device for environmental monitoring includes an insertion rod 1, a fixing frame 2 is fixedly connected to the upper surface of the insertion rod 1, a handle 3 is rotatably installed on the upper surface of the fixing frame 2, a threaded rod 4 is connected to the output shaft of the handle 3, the threaded rod 4 passes through the fixing frame 2 and the insertion rod 1, and a pull tube 7 is threadedly connected at the tail end, a piston plate 6 is fixedly connected to the bottom of the pull tube 7, the outer wall of the piston plate 6 is in close contact with the sample tube 5, a cover 9 is installed below the sample tube 5, a bracket 10 is fixedly connected to the cover 9, the middle thread of the bracket 10 is installed on the threaded rod 4, and the left and right sides of the bracket 10 are symmetrically assembled There is a pressure rod 11, the bottom end of the pressure rod 11 is fixedly connected to the upper surface of the sample tube 5, and the side end is connected to the insertion rod 1. A filter screen 8 is installed inside the bottom end of the sample tube 5 to effectively remove impurities such as aquatic plants and mud. A sealing rubber ring 12 is assembled on the upper surface of the cover 9. The sealing rubber ring 12 is adapted to the inner wall of the sample tube 5 to ensure the sealing of the device and prevent water sample leakage. The pressure rod 11 has a certain elasticity, and its upper end is inserted into the hole opened on the insertion rod 1, which is convenient for disassembly and cleaning of the device. The insertion rod 1 is L-shaped, and the bottom end is a quadrangular pyramid, which makes the device more stable and firm when inserted into the ground.

Since the piston plate 6 cannot rotate in the sample tube 5, the rotation of the threaded rod 4 can drive the pulling tube 7 to move upward, and the water to be sampled is then gathered into the sample tube 5. At the same time, the bracket 10 also moves upward under the rotation of the threaded rod 4 until the cover 9 seals the bottom of the sample tube 5, completing the sampling.
