[0002] Water quality testing is one of the important means to ensure the safety of water resources. Its main monitoring categories can be divided into two types: one is comprehensive indicators reflecting water quality conditions, such as temperature, color, turbidity, pH value, conductivity, suspended matter, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. Especially when testing surface water such as rivers, lakes, and seas, it is necessary to use a hydrological collection device to collect water at a specific coordinate position and depth, collect the water with different types of containers, and finally go to the laboratory for inspection and analysis; currently, the commonly used hydrological collection device is a barrel-shaped structure, the barrel bottom is a flat structure, and a water inlet structure is set at the center of the barrel bottom; for example, the Chinese utility model patent with patent publication number CN220019008U discloses a hydrological and water resources survey sampler, including a base, a support shaft, a protective cover, a top cover and multiple sampling tubes; the base in the technical solution is a cylindrical base; similar to this water sample collector, when sampling, is generally bottom-down, due to the large bottom area, after being placed in water, its sinking resistance is large, and the sinking speed is slow. When collecting water samples at deeper locations, it takes a long time, which reduces the efficiency of water sample collection. Utility Model Content

[0003] With regard to the water sample collector in the prior art, when sampling, due to the large bottom area, the sinking resistance is large after being put into water, the sinking speed is slow, and it takes a long time, which reduces the efficiency of water sample collection.

When sampling in deep water, the collector can sink to the sampling position quickly, thereby improving the sampling efficiency. A water inlet is arranged on the conical base, and a baffle cover which can be flipped inward is arranged on the water inlet. When the water bucket is in an upright state, the baffle cover falls freely by gravity and covers the water inlet. The bottom of the conical base is provided with a water outlet pipe, and a hand valve is arranged on the water outlet pipe. The lower end of the side wing is longer than the lower end of the water outlet pipe, so that when the sampler is placed, the lower ends of the three side wings serve as supporting feet to stand up the sampler, thereby facilitating water collection.

[0009] Preferably, there are three groups of flanks, the three groups of flanks are rotationally symmetrically distributed, and the angle between two adjacent flanks is 120 degrees.

[0010] Preferably, in order to reduce the overall volume of the sampler, there are six groups of side wings, the six groups of side wings are rotationally symmetrically distributed, and the angle between two adjacent side wings is 60 degrees.

[0011] Preferably, in order to make the periphery of the baffle cover fit more closely with the water inlet, the water inlet gradually increases from the outside to the inside of the conical base, and the baffle cover is formed with a sloped structure around it, which is adapted to the inner wall of the water inlet; after the baffle cover is closed, the outer end face of the baffle cover is consistent with the outer side face of the conical base, and the inner end face of the baffle cover is consistent with the inner side face of the conical base.

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-4 ; Clearly and completely describe the technical solutions in the embodiments of the utility model:

[0023] like Figure 1-3As shown, in the first embodiment of the utility model, a hydrological sampler comprises: a water collection bucket 10 for obtaining water samples; a crossbeam 4 is arranged in the middle of the top opening of the water collection bucket 10, and the two sides of the crossbeam 4 are respectively connected to a semicircular structure flip cover 1 2 and a flip cover 2 3 by hinges; the flip cover 1 2 and the flip cover 2 3 cover the top opening of the water collection bucket 10; the two ends of the crossbeam 4 are rotatably connected to the two ends of the semi-circular structure handle 1 by a shaft sleeve 5; in order to keep the water collection bucket 10 vertical after being lifted by a lifting rope, the middle position of the handle 1 is a semi-circular structure protruding outward, and the handle 1 is used. When the lifting rope is connected to the handle 1 through the safety buckle, the safety buckle automatically slides into the semi-circular structure when it is lifted; the lower end of the water bucket 10 is open and is provided with a conical base 7; three groups of side wings 6 are distributed on the outside of the water bucket 10 and the conical base 7, and the three groups of side wings 6 are rotationally symmetrically distributed, and the angle between two adjacent side wings 6 is 120 degrees; the side wings 6 can effectively prevent the sampler from rotating during the sinking process, so that it can sink stably; the conical base 7 can reduce the resistance during the sinking process, speed up the sinking process, and when sampling in deep water, the collector can sink quickly to the sampling position, thereby improving the sampling efficiency; Figure 3 The inner bottom of the conical base 7 is filled with a counterweight 17 to increase the sinking speed of the sampler; on the inner side of the conical base 7, above the counterweight 17 is a water inlet bin 14, and on the side of the water inlet bin 14 are three circular water inlets 8 evenly spaced, and the three circular water inlets 8 are connected to a baffle 15 through three hinges 18 on the inner side of the conical base 7, respectively. When the water bucket 10 is in an upright state, the baffle 15 falls freely by gravity to cover the water inlet 8; in order to make the periphery of the baffle 15 fit more closely with the water inlet 8, the water inlet 8 gradually increases from the outer side to the inner side of the conical base 7, and the baffle 15 is surrounded by an inclined structure that matches the inner wall of the water inlet 8; after the baffle 15 is closed, the outer end face of the baffle 15 is consistent with the outer side face of the conical base 7, and the inner end face of the baffle 15 is consistent with the inner side face of the conical base 7. The conical base 7 has a water outlet pipe 11 at the bottom, and a hand valve 9 is provided on the water outlet pipe 11; a water outlet hole 16 is provided in the middle of the counterweight body 17, and the water outlet hole 16 connects the water outlet pipe 11 with the water inlet bin 14; the lower end of the side wing 6 is longer than the lower end of the water outlet pipe 11, so that when the sampler is placed, the lower ends of the three side wings 6 serve as supporting feet to stand up the sampler, making it convenient to take water.

[0024] Specifically, the water bucket 10 is a transparent glass or transparent PVC structure with scale lines arranged thereon, and a thermometer is arranged inside the water bucket 10 .

[0025] When in use, the sampler is carried to the location where surface water is sampled, the lifting rope is connected to the handle 1 through the safety buckle, and the sampler is put into the water.
