Description

Technical Field

[0001] The utility model relates to the technical field of water sampling, and particularly relates to a lake water sampling device suitable for desert lakes. Background Art

[0002] Desert lakes refer to lakes located in desert areas, usually formed by the high groundwater level gushing out to the surface. These lakes are relatively scarce in desert areas but are of great significance to the local ecosystem and biodiversity.

[0003] The scarcity of desert lakes is well worth researching and protecting. During the research process, water samples of desert lakes need to be detected, and a water sampling device is commonly used. The water sampling device consists of a sampler and a storage device. The water in the desert lake is collected by the sampler, and the collected water is stored and detected by the storage device.

[0004] For example, the Chinese patent with the publication number CN218956191U discloses an automatic sampling device for lake water environment monitoring, which relates to the technical field of lake water environment monitoring. The conveying part includes a hull and a chain. A conveying mechanism is arranged on the hull, the chain is arranged on the wheel disc of the conveying mechanism, a plurality of magnets are arranged on the chain, and an automatic feeding mechanism is arranged on the hull; the sampling part includes a sampling mechanism and a bottom locking mechanism. The top cover is rotatably installed above the sampling pipe, the bottom cover is rotatably installed on the bottom plate below the sampling pipe, the rotation direction of the bottom cover is the same as that of the top cover, and the bottom locking mechanism is arranged on the bottom plate. The water pressure assists the bottom locking mechanism to close the bottom cover; the magnet on the sampling pipe is in contact and cooperation with the magnet, a locking cover mechanism is arranged above the sampling pipe, the water pressure assists the locking cover mechanism to close the sampling pipe, and an unlocking mechanism is arranged on the top cover. The beneficial effects are: it can automatically sample lake water at different depths at the same position; it is convenient to control variable experiments; the degree of automation is relatively high.

[0005] However, there are still some deficiencies in the above lake water sampling device during actual use:

[0006] 1. In the above prior art, the hull is used to ensure that the lake water sampling device can move and sample in various areas of the entire lake, and it can also automatically sample lake water at different depths at the same position; however, the volume of the ship is relatively large, and it requires complex processes and a large amount of manpower to place it into the lake. Moreover, when collecting water bodies in different areas, the ship is not convenient to move. Even more, for an area with harsh environment, personnel cannot approach the lake shore, resulting in difficulty in putting the ship into the lake.

[0007] 2. Secondly, in the prior art, the lake water is sampled by means of magnetic attraction in cooperation with the sampling bucket. However, there are a large number of aquatic plants such as waterweeds at the bottom of the lake, which may cause the sampling bucket to be entangled and thus drop, and the prior art cannot observe the bottom conditions of the lake.

[0008] 3. Then, in the prior art, the sealing performance of the collection equipment used to collect lake water is poor, which easily leads to leakage of the collected lake water.

[0009] Therefore, under the viewpoints stated above, there is still room for improvement in the existing automatic sampling device for lake water environment monitoring. Utility Model Content

[0036] The following will Figures 1-6 describe the embodiments of the present utility model in detail, but the present utility model can be implemented in many different ways defined and covered by the claims.

[0037] The embodiment of the present application discloses a lake water sampling device applicable to desert lakes. It should be noted that the lake water sampling device applicable to desert lakes is mainly used in the process of water body collection in some lakes with relatively harsh environments such as desert lakes. In terms of technical effects, it can avoid the problem that the collected lake water has poor sealing and is polluted during the collection process. Especially in some relatively harsh environments, where there are some swamps near the lake and the collectors cannot effectively approach the lake, the present utility model can effectively solve this problem. Further, the present application can also monitor and record the situation of the lake water during the process of collecting the lake water body, ensuring the stability and safety during the lake water collection.

[0038] First, in the prior art, for some areas with harsh environments, the collectors cannot approach the lake shore, resulting in increased difficulty in collecting lake water. Second, in the prior art, there are a large number of aquatic plants such as waterweeds at the bottom of the lake, which can cause the sampling bucket used for water intake to be entangled and fall, and the prior art cannot observe the bottom situation of the lake. Then, in the prior art, the collection equipment for collecting lake water has poor sealing, which is likely to cause the collected lake water to leak.

[0039] Embodiment 1: In view of the above problems, the present utility model proposes a lake water sampling device applicable to desert lakes.

[0040] Refer to Figure 1 As shown, a lake water sampling device applicable to desert lakes includes a telescopic member 1.

[0041] A sampler 2 is used for water intake operations in desert lakes with different depths in different regions. The sampler 2 is arranged on the telescopic member 1, and a towing rope 3 is provided between the telescopic member 1 and the sampler 2.

[0042] It should be noted that the telescopic member 1 can be telescoped to ensure that the sampler 2 can be thrown to various regions of the lake with the assistance of the towing rope 3, realizing the collection of water bodies in different regions of the lake.

[0043] The sampler 2 includes a conical-shaped stable protection shell 20 and a plurality of water intake cylinders 21 for water intake. The stable protection shell 20 is arranged on the towing rope 3, and a circular installation groove is opened at the bottom of the stable protection shell 20. The water intake cylinders 21 are arranged at equal intervals along the circumferential direction of the stable protection shell 20 inside the stable protection shell 20.

[0044] It should be noted that a plurality of water intake cylinders 21 are arranged inside the sampler 2, and the water at different depths in the lake can be sampled and detected through the plurality of water intake cylinders 21.

[0045] When water sampling is required from a desert lake, it should be noted that after the surrounding area of the desert lake absorbs the lake water, the surrounding area will become loose, and there will be dangerous situations such as swamps, so the personnel collecting the lake water cannot approach the desert lake. At this time, the collector can use the telescopic device in the present utility model to throw and extend the sampler 2 to directly above the desert lake, as follows.

[0046] Refer to Figure 2 As shown, which is the structural schematic diagram of the telescopic member 1 in the present utility model for telescoping. Specifically, the telescopic member 1 includes a plurality of telescopic sampling rods 10, and a plurality of telescopic sampling rods 10 are sequentially slidably sleeved on adjacent telescopic sampling rods 10, and the diameter of the telescopic sampling rods 10 gradually becomes smaller.

[0047] In the initial state, the telescopic sampling rods 10 are in a contracted state. The main purpose is to facilitate the whole lake water sampling device to be carried around, improve its portability, ensure that the whole lake water sampling device can quickly and portably follow the collector to move, and indirectly improve the efficiency of lake water collection.

[0048] When water sampling is carried out on a desert lake, the operator holds the telescopic sampling rod 10 at the end and pulls out the other telescopic sampling rods 10 retracted inside the end telescopic sampling rod 10, so as to ensure that the sampler 2 on the top telescopic sampling rod 10 moves to the sampling point above the desert lake.

[0049] If it is necessary to collect the lake water at the center of the desert lake, the collector can use the throwing method to throw the sampler 2 to the center of the lake, and then wait for a period of time to make the auxiliary throwing device 5 on the sampler 2 float stably on the lake surface of the whole desert lake.

[0050] Refer to Figure 2 And Figure 3 As shown, which is the structural schematic diagram of the lifting of the sampler 2 in the present utility model; specifically, one end of the towing rope 3 connecting the telescopic member 1 and the sampler 2 is provided with an auxiliary throwing device 5 at the top of the stable protection shell 20 of the sampler 2, and the other end is wound around the winding wheel 50. The winding wheel 50 is installed on the telescopic sampling rod 10 far away from the sampler 2 through a bracket.

[0051] It should be noted that a detachable winding wheel 50 is installed on the telescopic sampling rod 10 at the end of the telescopic member 1, and a winding handle for controlling the rotation of the winding wheel 50 is arranged on the outside of the winding wheel 50 (not shown in the figure). When the winding handle is rotated, the winding wheel 50 can be driven to rotate.

[0052] When the sampler 2 is thrown by the sampler, the booster 5 is also thrown into the desert lake together with the sampler 2. It should be noted here that the booster 5 mainly plays a floating role, and the buoyancy of the booster 5 is much greater than the gravity of the sampler 2 and the sampler 2 after taking water, ensuring that the booster 5 always floats on the lake surface.

[0053] Let's look at Figure 3 As shown, which is the structural schematic diagram of the booster 5 in the present invention; specifically, the booster 5 includes a booster floating block 51. Two rings 52 are arranged in the height direction of the booster floating block 51. The towing rope 3 is tied to the ring 52 at the top of the booster floating block 51, and a lifting rope 53 is arranged at the bottom of the booster floating block 51.

[0054] One end of the lifting rope 53 away from the booster floating block 51 is provided with a lifting wheel 54. The lifting wheel 54 is arranged in the stable protection shell 20, and a lifting motor 55 is arranged on one side of the lifting wheel 54. The lifting motor 55 is installed in the stable protection shell 20.

[0055] Rings 52 are arranged at the upper and lower ends of the booster floating block 51. One side of the ring 52 is connected to the towing rope 3, and the other side of the ring 52 is connected to the lifting rope 53. Therefore, the booster floating block 51 can be replaced, and the booster floating block 51 with different buoyancies can be replaced according to the volume of water body to be collected.

[0056] In the present invention, the buoyancy of the booster floating block 51 is much greater than the gravity of the sampler 2 and the sampler 2 after taking water. The purpose is to ensure that the booster floating block 51 can always float on the surface of the lake water, serving as a reference point to facilitate the accurate lifting and lowering of the water sampling cylinder 21 for subsequent lake water collection. The booster floating block 51 can also be replaced to improve the adaptive adjustment of the volume of the collected lake water in the present invention, greatly improving the applicability of the device.

[0057] And in the initial state, the lifting ropes 53 are all wound on the lifting wheel 54, so the entire sampler 2 is close to the position of the booster floating block 51.

[0058] During the specific implementation process, after the booster floating block 51 floats on the lake surface, control the start and stop of the lifting motor 55 to ensure the release of the lifting rope 53, and ensure that the sampler 2 for lake water collection can collect lake water at different depths by releasing different lengths of the lifting rope 53.

[0059] Let's look at Figure 2 and Figure 3 As shown, which is the structural schematic diagram for monitoring the safety and smoothness of the lifting of the sampler 2 in this embodiment; specifically, an observation component 6 for monitoring the underwater scene of the desert lake is also provided on the outer wall of the stable protection shell 20. The observation component 6 includes an observation camera 60 and an observation screen 61 that can be wirelessly connected to the observation camera 60.

[0060] Observation cameras 60 are evenly distributed on the outer wall of the stable protective shell 20 along the vertical central axis of the stable protective shell 20, and the observation screen 61 is arranged on the telescopic sampling rod 10.

[0061] A number of observation cameras 60 are arranged on the outside of the stable protective shell 20. Through these cameras, the environment within the 360-degree range of the entire stable protective shell 20 is displayed on the observation screen 61. It can not only monitor the lake water collection of the stable protective shell 20, but also ensure the safety of the sampler 2 at the bottom of the lake.

[0062] Because aquatic plants grow at the bottom of the lake in different areas, when the sampler 2 moves towards the bottom of the lake, it may cause the aquatic plants to entangle with the sampler 2. At this time, the observation camera 60 can accurately monitor the sinking situation of the sampler 2 to avoid the sampler 2 being entangled with the aquatic plants.

[0063] Refer to Figure 4 As shown, it is a schematic structural diagram of the main power source in the present invention; a battery compartment 7 is opened at the top of the stable protective shell 20, and a waterproof battery 9 for supplying power to the entire stable protective shell 20 is inserted and installed in the battery compartment 7.

[0064] The waterproof battery 9 can be replaced by plugging and unplugging, and a waterproof sealing ring is provided between the waterproof battery 9 and the stable protective shell 20 to prevent the water source in the desert lake from causing the entire device to short-circuit when encountering water.

[0065] At the same time, the waterproof battery 9 provides power for the entire device to ensure the stability of the entire device during operation.

[0066] Refer to Figure 5 As shown, it is a schematic structural diagram of the working process of the water intake cylinder 21 for water intake in the present invention; specifically, an electric opening and closing unit 4 for opening and closing a sealing circular plate 210 that tightly fits the bottom of a number of water intake cylinders 21 is further arranged in the stable protective shell 20. The electric opening and closing unit 4 includes a micro-sampling motor 40, a sampling plate 41, and a linkage protrusion 42.

[0067] The micro-sampling motor 40 is installed in the stable protective shell 20, the output shaft of the micro-sampling motor 40 faces downward, and the micro-sampling motor 40 is waterproofed. The sampling plate 41 is installed on the output shaft of the micro-sampling motor 40, and the sampling plate 41 is rotatably arranged on the inner wall of the stable protective shell 20. The linkage protrusion 42 is connected to the bottom of the sampling plate 41, and the linkage protrusion 42 is in active contact with a number of linkage columns 213.

[0068] It should be noted that the micro-sampling motor 40 is powered by the waterproof battery 9.

[0069] During the specific implementation process, when the entire sampler 2 sinks to the designated height in the lake water, the micro-sampling motor 40 starts, and the micro-sampling motor 40 drives the sampling plate 41 to rotate at a constant speed. At this time, the linkage protrusion 42 on the sampling plate 41 squeezes the linkage column 213 directly below it, causing the linkage column 213 to squeeze the sealing circular plate 210 connected below it, so that the sealing circular plate 210 at the bottom of the water intake cylinder 21 is separated from the water intake cylinder 21. At this time, the lake water will enter the water intake cylinder 21 through the gap between the sealing circular plate 210 and the water intake cylinder 21. After a large amount of lake water fills the water intake cylinder 21, the sampling plate 41 and the linkage protrusion 42 rotate and move away from the linkage column 213. After the external force on the linkage column 213 disappears, under the pulling force of the linkage spring 214, the linkage column 213 drives the sealing circular plate 210 to fit back on the water intake cylinder 21 again, realizing the collection and storage of the lake water.

[0070] Refer to Figure 6 As shown, which is the structural schematic diagram of the water intake cylinder 21 in the present utility model; specifically, a sealing circular plate 210 is also movably abutted against the bottom of the water intake cylinder 21, and a sealing rubber block 211 is installed at the upper end of the sealing circular plate 210.

[0071] One end of the water intake cylinder 21 close to the sealing circular plate 210 is connected with an auxiliary bracket 212. The sealing circular plate 210 is also vertically provided with a linkage column 213, and the linkage column 213 extends upward and slidably penetrates through the top end of the water intake cylinder 21. A linkage spring 214 is sleeved on the linkage column 213, with one end provided on the auxiliary bracket 212 and the other end provided on the sealing circular plate 210.

[0072] It should be noted that a sealing rubber block 211 is provided on the sealing circular plate 210, which can play a sealing role to prevent the lake water from leaking when collecting the lake water.

[0073] A rubber protection waterproof ring 215 is provided at the position where the linkage column 213 penetrates through the stable protection shell 20. The purpose is to ensure that when the linkage column 213 slides, the lake water is prevented from leaking through the gap between the linkage column 213 and the stable protection shell 20.

[0074] In the initial state, the sealing circular plate 210 is always abutted against the water intake cylinder 21 under the drive of the linkage spring 214. When an external force squeezes the linkage column 213, the linkage column 213 squeezes the sealing circular plate 210, causing the sealing circular plate 210 to move away from the water intake cylinder 21.

[0075] When the external force on the linkage column 213 disappears, the elastic force of the linkage spring 214 drives the sealing circular plate 210 to fit back against the water intake cylinder 21 again.

[0076] Look back Figure 5As shown, it is a schematic diagram of the connection structure between the water intake cylinder 21 and the stable protective shell 20 in the present utility model; the water intake cylinder 21 and the stable protective shell 20 are connected by means of threads.

[0077] The water intake cylinder 21 can be installed on the stable protective shell 20 by rotation. After collecting lake water inside it, it can be removed by rotation, and then the water intake cylinder 21 can be transported to the designated area for detection.

[0078] During operation: First step, when taking water samples from a desert lake, the operator holds the telescopic sampling rod 10 at the end and pulls out the other telescopic sampling rods 10 that are retracted inside the end telescopic sampling rod 10, so as to ensure that the sampler 2 on the top telescopic sampling rod 10 moves to the sampling point above the desert lake.

[0079] Second step: When it is necessary to collect the lake water at the center of the desert lake, the sampler 2 can be thrown to the center of the lake by the collector, and then left stationary for a period of time, so that the booster 5 on the sampler 2 can stably float on the surface of the entire desert lake.

[0080] Third step: When the collector throws the sampler 2, the booster 5 is also thrown into the desert lake together with the sampler 2, and the booster float 51 floats on the lake surface.

[0081] Fourth step: After the booster float 51 floats on the lake surface, control the start and stop of the lifting motor 55 to ensure the release of the lifting rope 53, and ensure that the sampler 2 for collecting lake water collects lake water at different depths by releasing lifting ropes 53 of different lengths.

[0082] Fifth step: When the entire sampler 2 sinks to the designated height of the lake water, the micro-sampling motor 40 starts, and the micro-sampling motor 40 drives the sampling plate 41 to rotate at a constant speed. At this time, the linkage protrusion 42 on the sampling plate 41 presses the linkage column 213 directly below it, so that the linkage column 213 presses the connected sealing circular plate 210 below, causing the sealing circular plate 210 at the bottom of the water intake cylinder 21 to separate from the water intake cylinder 21. At this time, the lake water will enter the water intake cylinder 21 through the gap between the sealing circular plate 210 and the water intake cylinder 21. After a large amount of lake water fills the water intake cylinder 21, the sampling plate 41 and the linkage protrusion 42 rotate and move away from the linkage column 213. After the linkage column 213 loses the external pressure, under the pulling force of the linkage tension spring 214, it drives the sealing circular plate 210 to fit on the water intake cylinder 21 again, realizing the collection and storage of lake water.

[0083] Sixth step: The water intake cylinder 21 can be removed from the stable protective shell 20 by means of threaded connection.
