At present, a variety of water sample collectors have appeared on the market, such as the Chinese patent file with the announcement number CN210243265U, which discloses a new type of stainless steel water sample collector, which comprises a main cylinder, a fixed cylinder cover is arranged at the top of the main cylinder, a fixed rotating shaft is arranged at the center of the fixed cylinder cover, a folding cover is rotatably connected to the front side of the fixed rotating shaft, connecting seats are arranged on both sides of the main cylinder, pull rings are connected to the outer side of the connecting seats, a water collecting bin is arranged at the center of the main cylinder, a scale line is arranged on the outer side of the water collecting bin, a fixed baffle is arranged at the bottom of the main cylinder, a water inlet groove is arranged at the center of the fixed baffle, a fixed cylinder bottom is arranged at the bottom of the water inlet groove, and a floating cover is arranged at the center of the fixed cylinder bottom.

[0003] Although the new type of stainless steel water sample collector can ensure water sample collection and prevent water sample loss by using the floating cover to move in the fixed area, the material of the collector itself does not affect the water quality of the water sample, but it is difficult to adjust the depth of the main cylinder in the water during use, and it is not possible to accurately collect water samples at a predetermined depth. Due to the different depth levels of the water body, the composition of the water sample may be different due to factors such as temperature and dissolved substance concentration, and if it cannot be collected at a specific depth, it will cause errors in the water quality detection results.

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail in combination with the drawings and specific embodiments.

[0028] As Figure 1As shown, the embodiment provides a water sample collecting device, which comprises a barrel 1, a length adjusting mechanism 2 and a sampling mechanism 3. The top of the barrel 1 is provided with a cover plate 101, the bottom of the barrel 1 is provided with a bottom plate 102, and the side of the barrel 1 is provided with a sampling port 103 for entering water samples. Specifically, the sampling port 103 in the embodiment is provided with two, and the two sampling ports 103 are respectively symmetrically arranged on the two sides of the lower part of the barrel 1. The cover plate 101 is connected with the barrel 1 through the length adjusting mechanism 2, and the length adjusting mechanism 2 can adjust the distance between the cover plate 101 and the barrel 1 to adjust the sampling depth of the sampling port 103. The sampling mechanism 3 comprises a sampling rod and a sampling head. The sampling rod is movably arranged in the barrel 1 from top to bottom, and the upper end of the sampling rod is telescopic to be arranged outside the cover plate 101. The sampling head is arranged at the lower end of the sampling rod and can form a water storage space with the bottom plate 102 in the barrel 1. A filter screen 301 is arranged in the sampling head. When the upper end of the sampling rod is moved to a position close to the sampling port 103, the sampling port 103 can be communicated with the water storage space through the sampling head, so that the water sample enters the water storage space through the filter screen 301.

[0029] In the embodiment, as shown, Figure 2 The length adjusting mechanism 2 comprises an adjusting assembly, which comprises a sliding groove and a sliding rod 201. The sliding groove is arranged in the upper barrel wall of the barrel 1 from top to bottom, and a plurality of limiting holes 202 are arranged on the outer wall of the sliding groove. The limiting holes 202 are arranged from top to bottom. The sliding rod 201 is slidably inserted into the sliding groove, and the upper end of the sliding rod 201 is fixedly connected with the cover plate 101. The lower end of the sliding rod 201 is provided with a spring protrusion 203, which can be clamped with any limiting hole 202 to limit the insertion depth of the sliding rod 201. In use, the spring protrusion 203 is pressed to make the sliding rod 201 slide up and down in the sliding groove to adjust the insertion depth of the sliding rod 201, that is, to adjust the distance between the cover plate 101 and the barrel 1. When the barrel 1 is placed in the water body to be sampled, the position of the sampling port 103 can reach the required sampling depth. The spring protrusion 203 is released to be clamped with the limiting hole 202 at the corresponding position, so as to fix the position of the sliding rod 201, thereby adjusting the sampling depth of the sampling port 103.

[0030] Further, the adjusting assembly is provided with two groups, and the two groups of adjusting assemblies are respectively symmetrically arranged on the two sides of the upper part of the barrel 1, thereby increasing the stability of the connection between the cover plate 101 and the barrel 1.

[0031] In the embodiment, the sampling rod comprises a push-pull rod 302, a threaded rod 303 and a handle 304.

The upper block 305 is fixedly connected to the lower end of the sampling rod, and the lower block 306 is fixedly connected to the bottom of the upper block 305 through the connecting rod 307. The lower block 306 and the bottom plate 102 can form a water storage space. The lower block 306 is provided with a filter port, and the filter screen 301 is arranged in the filter port. When the sampling rod is moved so that the upper block 305 and the lower block 306 are located above and below the sampling port 103 respectively, the sampling port 103 can be communicated with the water storage space through the filter port.

[0033] During sampling, the handle 304 is rotated to drive the threaded rod 303 to rotate, so as to adjust the depth of the threaded rod 303 screwed into the push-pull rod 302, thereby matching the length of the sampling rod with the distance between the cover plate 101 and the cylinder 1. The handle 304 is pulled to drive the threaded rod 303, the push-pull rod 302 and the sampling head to move up and down in the cylinder 1, so as to adjust the position of the sampling head. Specifically, the device state shown in Figure 2 is described. At this time, the upper block 305 seals the sampling port 103. The handle 304 is pulled upward to move the upper block 305 upward to open the sampling port 103, so that the water sample enters the cylinder 1 between the upper block 305 and the lower block 306, and then enters the water storage space between the lower block 306 and the bottom plate 102 through the filter port of the lower block 306. In this process, the filter screen 301 in the filter port filters the water sample to remove impurities in the water sample, thereby improving the accuracy of subsequent water quality detection. The handle 304 is continuously pulled upward to move the lower block 306 upward to seal the sampling port 103, thereby protecting the collected water sample. After the water sample collection is completed, the device is lifted to the ground, and the handle 304 is continuously pulled upward to move the lower block 306 upward to open the sampling port 103. The water quality detection equipment is connected to the sampling port 103, and data recording and analysis are performed by a computer.
