Description

Technical Field

[0001] The invention belongs to the technical field of wetland water sample collection, and in particular relates to a shuttle-shaped wetland water sample collection device. Background Art

[0002] Wetlands have ecological significance such as maintaining biodiversity, regulating climate, and purifying water quality. At the same time, they have economic significance such as providing resources and tourism. In terms of society, wetlands can carry out scientific research and education and have certain cultural value.

[0003] Wetland water sample monitoring is an important part of the study of wetland functional characteristics. Therefore, a water sample collection device is needed to collect water samples from the wetland regularly. However, the existing water sample collection device is easily disturbed by various aquatic plants and animals during the water sample collection process, which affects the collection of water samples. In addition, wetland water sample collection is different from river water sample collection. There are a large number of vegetation growing in wetlands. Currently, ordinary water sample collectors are generally cylindrical, which has the problem of difficulty in launching and discharging water. Therefore, a shuttle-shaped wetland water sample collection device is urgently needed to solve the above problems. Summary of the invention

[0004] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a shuttle-shaped wetland water sample collection device.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A shuttle-shaped wetland water sample collection device comprises a collection container, which is arranged in a shuttle-shaped structure. A sampling cavity is arranged in the collection container. A plurality of water inlets connected to the sampling cavity are arranged around the outer lower side of the collection container. A plurality of water inlets are evenly arranged on the collection container. A switch assembly is installed in the water inlet. A water outlet connected to the sampling cavity is provided on the lower side of the water inlet of the collection container. A water outlet assembly is installed in the water outlet. A counterweight assembly is installed at the bottom of the sampling cavity. A hollow hanging hole is provided on the top of the collection container.

[0007] It is further defined that the collection container includes an upper conical shell and a lower conical shell, the inner top of the lower conical shell is provided with an external thread column, the bottom of the upper conical shell is provided with an internal thread groove corresponding to the external thread column, and the upper conical shell and the lower conical shell are installed by thread locking cooperation between the external thread column and the internal thread groove.

[0008] It is further defined that the upper conical shell and the lower conical shell are both made of transparent material, and scale lines are provided on one side of the upper conical shell and the lower conical shell. Such a structural design is convenient for recording the amount of water intake and discharge.

[0009] It is further defined that the switch assembly includes a movable connecting member, one side of the movable connecting member is installed at the bottom of the water inlet, the other side of the movable connecting member is installed with a cover plate, the cover plate is arranged on the inner side of the water inlet, and a filter screen is also installed on the outer side of the water inlet. Such a structural design facilitates the automatic opening of the water inlet after water enters the water to collect water, and the automatic closing of the water inlet when water is discharged.

[0010] It is further defined that the filter screen is designed to be detachable and installed in the water inlet, which facilitates the removal, replacement or maintenance of the filter screen.

[0011] It is further defined that a positioning block is provided on one side of the top of the cover plate, and a step groove is provided on the inner side of the water inlet at a position corresponding to the positioning block, and the positioning block is installed in the step groove. Such a structural design has a limiting effect when the cover plate is automatically closed during water discharge, preventing the cover plate from not blocking the water inlet and causing water sample leakage.

Such a structural design can block the water outlet and prevent leakage of water samples.

[0013] It is further defined that the counterweight assembly is a lead weight. Such a structural design facilitates the collection container to sink to the bottom of the water for sampling.

[0014] It is further defined that the upper side of the collection container is provided with an assembly groove between the hollow hanging hole and the sampling cavity, a sealed protective shell is installed in the assembly groove, a battery is installed in the sealed protective shell, a signal light is connected to the output end of the battery, the signal light is installed on both sides of the top of the collection container, and the assembly groove is provided with sealing blocks on both sides of the sealed protective shell. Such a structural design can play a small identification effect in dim light conditions.

[0015] The beneficial effects of the present invention are as follows: the present invention adopts a shuttle-shaped collection container, and compared with the cylindrical samplers currently on the market, the present invention has smaller 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 hollow hanging 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 to prevent aquatic animals and plants from entering the sampling cavity in the collection container and affecting the collection of conventional water samples. The switch component can automatically seal and open the water inlet, which is convenient for sampling and sealing. The water outlet component of the water outlet can ensure that the water sample will not leak autonomously. The present invention is simple to operate, suitable for field operations such as wetland water sample collection, has strong anti-interference ability, and is conducive to the subsequent water quality index detection and other work.

DETAILED DESCRIPTION

[0021] 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 in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment 1, as Figure 1 and Figure 2As shown, a shuttle-shaped wetland water sample collection device is provided, wherein the collection container 1 is arranged in a shuttle-shaped structure, a sampling cavity 2 is arranged in the collection container 1, a plurality of water inlets 3 connected with the sampling cavity 2 are arranged on the outer lower side circumference of the collection container 1, a plurality of water inlets 3 are evenly arranged on the collection container 1, a switch assembly 4 is installed in the water inlet 3, a water outlet 5 connected with the sampling cavity 2 is provided on the lower side of the water inlet 3 of the collection container 1, a water outlet assembly 6 is installed in the water outlet 5, a counterweight assembly 7 is installed at the bottom of the sampling cavity 2, and a hollow hanging hole 8 is provided on the top of the collection container 1.

[0023] In the present embodiment, when in use, by connecting a hanging sampling rope in the hollow hanging hole 8 on the top of the collection container 1 or using a fishing rod or other devices, the error caused by the disturbance of aquatic plants and animals near the shore to the water quality can be avoided, and long-distance water sample collection can also be achieved. When the collection container 1 enters the water, the counterweight component 7 allows the collection container 1 to sink into the water. Due to the action of the water pressure, the switch component 4 automatically opens, allowing the water source to enter the sampling cavity 2 in the collection container 1 through the water inlet 3 for sampling. The design of multiple water inlets 3 accelerates the water inlet speed. After the sampling is completed, when the collection container 1 is lifted out of the water, due to the difference in internal and external water pressures, the switch component 4 automatically closes and closes the water inlet 3. When taking water, it is only necessary to push the water outlet component 6 to allow the water in the sampling cavity 2 to flow out from the water outlet 5.

[0024] Embodiment 2, as Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 1. The collection container 1 includes an upper conical shell 9 and a lower conical shell 10. The inner top of the lower conical shell 10 is provided with an external thread column 11, and the bottom of the upper conical shell 9 is provided with an internal thread groove 12 corresponding to the external thread column 11. The upper conical shell 9 and the lower conical shell 10 are installed by thread locking cooperation between the external thread column 11 and the internal thread groove 12.

[0025] In this embodiment, the upper conical shell 9 and the lower conical shell 10 are installed by thread locking cooperation of the external thread column 11 and the internal thread groove 12, which facilitates later disassembly for cleaning and maintenance. In addition, the shuttle shape formed by the combination of the upper conical shell 9 and the lower conical shell 10 has less resistance when entering and exiting the water surface, and is easy to use.

[0026] Embodiment 3, as Figure 1 As shown, this embodiment adds the following structure on the basis of embodiment 2: the upper conical shell 9 and the lower conical shell 10 are both made of transparent material, and a scale line 13 is also provided on one side of the upper conical shell 9 and the lower conical shell 10. Such a structural design facilitates recording the amount of water intake and discharge.

[0027] In this embodiment, when collecting water samples, the amount of water taken in and released can be recorded through the transparent upper conical shell 9 and the lower conical shell 10 in combination with the scale lines 13.

[0028] Embodiment 4, as Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 1, the switch assembly 4 includes a movable connecting member 14, one side of the movable connecting member 14 is installed at the bottom of the water inlet 3, the other side of the movable connecting member 14 is installed with a cover plate 15, the cover plate 15 is arranged on the inner side of the water inlet 3, and a filter screen 16 is also installed on the outer side of the water inlet 3.

[0029] In this embodiment, when the collection container 1 is immersed in water, due to the effect of external water pressure, the cover 15 is automatically opened under the effect of the movable connection member 14, so that the water source enters the sampling cavity 2 in the collection container 1 through the filter screen 16 in the water inlet 3 to perform sampling. After the sampling is completed, when the collection container 1 is lifted out of the water, due to the difference in internal and external water pressure, the cover 15 is automatically closed along the movable connection member 14.

[0030] Embodiment 5, as Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 4, and the filter screen 16 is designed to be detachable and installed in the water inlet 3.

[0031] In this embodiment, after use, the filter screen 16 can be removed from the water inlet 3 to be replaced or maintained so that the filter screen 16 can play the filtering and blocking effects next time.

[0032] Embodiment 6, as Figure 2 As shown, this embodiment adds the following structure on the basis of Embodiment 4: a positioning block 17 is further provided on one side of the top of the cover plate 15 , a step groove 18 is provided on the inner side of the water inlet 3 at a position corresponding to the positioning block 17 , and the positioning block 17 is installed in the step groove 18 .

[0033] In this embodiment, when the collection container 1 is lifted out of the water, due to the difference in water pressure inside and outside, the cover 15 automatically closes along the movable connection piece 14, and at the same time, the cover 15 drives the positioning block 17 to be inserted into the step groove 18. Through the cooperation of the positioning block 17 and the step groove 18, the cover 15 stops moving after closing the water inlet 3, thereby preventing the cover 15 from continuously moving to generate gaps, which may cause leakage of the water sample collected inside.

[0034] Embodiment 7, as Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 1. The water outlet assembly 6 includes a mounting frame 19 installed in the sampling chamber 2. The mounting frame 19 is arranged in a door-shaped structure. A telescopic rod 20 is installed at the bottom of the mounting frame 19. A plugging head 21 is connected to the other side of the telescopic rod 20. The plugging head 21 is installed in the water outlet 5. A spring 22 is installed on the inner side of the plugging head 21. The free end of the spring 22 is installed at the bottom of the mounting frame 19.

[0035] In this embodiment, when it is necessary to draw water, the plugging head 21 is lifted up by using an ordinary pole, so that the plugging head 21 moves inward after being subjected to force, thereby causing the plugging head 21 to push the telescopic rod 20 to guide movement, and at the same time squeeze the spring 22 to compress and deform the spring 22. When the plugging head 21 leaves the water outlet 5, the water sample in the sampling chamber 2 can flow out of the water outlet 5 to carry out water drawing. After the water drawing is completed, the pressure applied to the plugging head 21 is lost, so that the plugging head 21 is pushed to seal the water outlet 5 under the effect of the rebound force of the spring 22 to prevent leakage of the water sample.

[0036] Embodiment 8, as Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 1, and the counterweight assembly 7 is a load-bearing lead block 23.

[0037] In this embodiment, when in use, the weighted lead block 23 helps to keep the collection container 1 vertically in and out of the water, thereby reducing the interference of bottom mud on sampling.

[0038] Embodiment 9, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure on the basis of embodiment 1: an assembly groove 24 is provided on the upper side of the collection container 1 between the hollow hanging hole 8 and the sampling chamber 2, a sealed protective shell 25 is installed in the assembly groove 24, a battery 26 is installed in the sealed protective shell 25, and a signal light 27 is connected to the output end of the battery 26. The signal light 27 is installed on both sides of the top of the collection container 1, and the assembly groove 24 is installed with sealing blocks 28 on both sides of the sealed protective shell 25.

[0039] In this embodiment, when the light is dim, the battery 26 is controlled to output electricity to the signal light 27, and the signal light 27 is turned on to play the role of auxiliary identification. The sealing block 28 and the sealing protective shell 25 are sealed to improve the sealing performance and service life of the battery 26, and prevent the phenomenon of short circuit caused by water ingress.
