SUMMARY

[0004] In view of the problems in the above background art, the utility model aims at providing a shuttle wetland water sample collection device.

[0005] To achieve the above technical purpose, the utility model adopts the following technical scheme:

[0006] A shuttle wetland water sample collection device, including shuttle container, the top of the shuttle container is equipped with the hook hole, the inner side bottom of the shuttle container is installed with the counterweight, the lower side of the shuttle container is equipped with a plurality of water inlets, a plurality of water inlets are evenly arranged on the lower side of the shuttle container, the interval between two adjacent water inlets is equal, the water inlet is hingedly installed with the flap, the water inlet is installed with the filter screen on the outside of the flap, the bottom of the shuttle container is equipped with the water outlet, the water outlet is installed with the obturator.

[0007] Further limited, the shuttle container is made of transparent material. Such structure design is convenient for checking the water source collection state.

[0008] Further limited, the counterweight is a lead block arranged in a conical structure. Such structure design helps to keep the shuttle container vertical in and out of water, and the lead block also has good corrosion resistance, so that its service life is long.

[0009] Further limited, the filter screen is a detachable honeycomb filter screen. Such structure design can avoid aquatic animals and plants entering the shuttle container, affecting the collection of conventional water sample, and also facilitates disassembly and cleaning.

[0010] It is further defined that the plugging head is a rubber plugging head. Such a structural design can block the water outlet when collecting water samples, and the plugging head has a certain elasticity, so when the plugging head is inserted into the water outlet, it will fit with the inner wall of the water outlet, thereby improving the sealing performance.

[0011] The beneficial effects of the present invention are as follows: the present invention uses a shuttle-shaped container, which is arranged in a shuttle shape. Compared with the cylindrical samplers currently on the market, the present invention has less resistance to entering and exiting the water surface during sampling, is not easily disturbed by aquatic animals and plants, and is convenient for sampling. The hook hole on the top can be used to hang a sampling rope or be used in conjunction with a fishing rod and other devices. The design of multiple water inlets at the bottom accelerates the water inlet speed. Each water inlet is installed with a filter screen to prevent aquatic animals and plants from entering the shuttle-shaped container and affecting the collection of conventional water samples. The present invention is simple to operate, suitable for field operations such as wetland water sample collection, has strong anti-interference ability, and is helpful for the subsequent water quality index detection and other work.

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0018] like Figs. 1-2 As shown, the utility model is a shuttle-shaped wetland water sample collection device, a hook hole 2 is provided on the top of the shuttle-shaped container 1, a counterweight 3 is installed on the inner bottom of the shuttle-shaped container 1, a plurality of water inlets 4 are provided on the lower side of the shuttle-shaped container 1, and the plurality of water inlets 4 are evenly arranged on the lower side of the shuttle-shaped container 1, wherein the intervals between two adjacent water inlets 4 are equal, a flip cover 5 is hingedly installed in the water inlet 4, a filter screen 6 is installed on the outside of the flip cover 5 of the water inlet 4, a water outlet 7 is provided on one side of the bottom of the shuttle-shaped container 1, and a sealing head 8 is installed in the water outlet 7.

[0019] Preferably, the shuttle-shaped container 1 is made of transparent material. This design facilitates the observation of the water collection status. In fact, other structural shapes of the shuttle-shaped container 1 can also be considered according to specific conditions.

[0020] Preferably, the counterweight 3 is a lead block with a conical structure. This design helps to keep the shuttle-shaped container 1 vertically entering and leaving water, and the lead block has good corrosion resistance, thus having a long service life. In fact, other structural shapes of the counterweight 3 can also be considered according to specific conditions.

[0021] Preferably, the filter screen 6 is a detachable honeycomb filter screen. This design can prevent aquatic animals and plants from entering the shuttle-shaped container 1, thus affecting the collection of regular water samples, and also facilitates the disassembly and cleaning. In fact, other structural shapes of the filter screen 6 can also be considered according to specific conditions.

[0022] Preferably, the plug 8 is a rubber plug. This design can plug the water outlet 7 when collecting water samples, and the plug 8 has a certain elasticity, so that when the plug 8 is inserted into the water outlet 7, it will fit the inner wall of the water outlet 7, thus improving the sealing performance. In fact, other structural shapes of the plug 8 can also be considered according to specific conditions.

[0023] In use, the hook hole 2 at the top of the shuttle-shaped container 1 is connected with a sampling rope or used in cooperation with a fishing rod and the like, so as to avoid the disturbance of aquatic animals and plants near the shore to the water quality, and to achieve long-distance water sampling. When the shuttle-shaped container 1 enters water, the flip cover 5 is automatically opened due to the external water pressure, so that water enters the shuttle-shaped container 1 for sampling. During sampling, aquatic animals and plants are prevented from entering the shuttle-shaped container 1 by the filter screen 6, thus affecting the collection of regular water samples. When the sampling is completed, the flip cover 5 is automatically closed due to the difference in water pressure, thus closing the water inlet 4. When taking water, the plug 8 is removed from the water outlet 7, so that the water in the shuttle-shaped container 1 flows out of the water outlet 7.

[0024] The multiple water inlets 4 on the lower side of the shuttle-shaped container 1 ensure the water inlet speed and reduce the sampling time.

[0025] The shuttle-shaped design of the shuttle-shaped container 1 has smaller water surface resistance than the cylindrical sampler on the market, is not easily disturbed by aquatic animals and plants, and facilitates the sampling operation.

[0026] The above examples only illustrate the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above examples without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed by the present application shall be covered by the claims of the present application.
