Description

Technical Field

[0001] This invention relates to the field of lake ecological environment water quality monitoring technology, specifically a lake ecological environment monitoring sampling device. Background Technology

[0002] Lake ecological environment monitoring and sampling refers to the collection of data on various environmental factors, species, and biological communities within a lake ecosystem using scientific sampling methods and techniques. This data is used to assess key indicators such as the health status, pollution levels, and biodiversity of the lake's ecosystem. Lake ecological environment monitoring and sampling is of great significance for ecological protection, resource management, pollution control, and ecological restoration. Lake ecological environment monitoring and sampling mainly includes water quality monitoring sampling, biological monitoring sampling, sediment monitoring sampling, and air and precipitation monitoring. Through scientific lake ecological environment monitoring and sampling, we can better understand changes in lake ecosystems, promptly identify problems, and take measures to protect the lake's ecological environment.

[0003] Lake water sampling is a core component of lake ecological environment monitoring because lake water can reflect the overall health status, pollution level, and trends of the lake ecosystem to a greater extent. Furthermore, by collecting and analyzing lake water samples, key information about water quality, nutrient status, pollution sources, and ecological health can be obtained, facilitating targeted restoration measures for the lake in the future.

[0004] Currently, commonly used lake water sampling devices require the sampling device to be pre-sampling into the lake at the designated depth when sampling at different predetermined depths. The sampling device has multiple water tanks arranged from top to bottom, and then the controller electrically controls the solenoid valve on the inlet pipe connected to each water tank to open, so that lake water enters each water tank through the inlet pipe to complete the water sampling. However, the controller and solenoid valve may become unstable in electrical performance due to long-term exposure to a humid environment, which may affect the normal use of the equipment, increase the risk of equipment failure, and thus affect normal sampling. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a lake ecological environment monitoring and sampling device that does not use electrical components, thereby avoiding the risk of equipment failure and the occurrence of unstable equipment use.

[0006] To solve the above-mentioned technical problems, the present invention provides a lake ecological environment monitoring and sampling device, comprising multiple water tanks connected from bottom to top, a sealing layer on the outer wall of each water tank, first inlet pipes evenly spaced on each water tank, and a first one-way valve on each first inlet pipe, and further comprising:

[0007] The casing is located outside multiple water tanks, and the multiple water tanks are slidably connected to the inner wall of the casing along the vertical direction. The casing has multiple second water inlet pipes that correspond one-to-one with the water tanks. The distance between two adjacent second water inlet pipes is equal, and each second water inlet pipe is equipped with a second one-way valve. The bottom of the casing is equipped with a third water inlet pipe, and the third water inlet pipe is equipped with a third one-way valve.

[0008] The piston plate is located inside the casing between the third water inlet pipe and the water storage tank, and is slidably connected to the inner wall of the casing. The piston plate and the water storage tank are connected by a connecting rod.

[0009] The elastic element connects the water tank to the top of the casing.

[0010] Before sampling, the external water needs to overcome the elastic force of the elastic element so that the first water inlet pipe always abuts against the sealing layer before reaching the specified sampling depth; when sampling reaches the specified depth, the elastic element is compressed, and the piston plate pushes the water tank upward through the connector so that multiple second water inlet pipes correspond one-to-one with multiple first water inlet pipes and are connected.

[0011] Preferably, the device further includes an alignment component to ensure that the first and second water inlet pipes located on the water tank are aligned during sampling. The alignment component includes two push rods and two telescopic rods. The two push rods are symmetrically arranged on both sides of the connecting rod, and the two telescopic rods are symmetrically arranged on both sides of the connecting rod in the horizontal direction. The top end of each push rod is hinged to the piston plate, and the bottom end of each push rod is hinged to the telescopic end of the telescopic rod. The fixed end of each telescopic rod is connected to the connecting rod. The housing is symmetrically provided with through holes for the telescopic ends of the telescopic rods to pass through. The housing is sealed with a sealing shell communicating with each through hole. When the push rod moves upward under the action of the piston plate, it pushes the telescopic ends of the two telescopic rods through the through holes into the sealing shell, so that the multiple second water inlet pipes correspond one-to-one with the multiple first water inlet pipes and are connected.

[0012] Preferably, the telescopic end of each telescopic rod is engaged with each sealing shell.

[0013] Preferably, the telescopic rod has a first rack on its outer wall in the horizontal direction at the telescopic end. A drive gear that meshes with the first rack is rotatably connected to the inner wall of the housing. A second rack that is parallel to the first rack is also meshed on the drive gear. A push plate is fixed to the top of the second rack. The top of the push plate is slidably connected to the inner wall of the housing in the horizontal direction. The push plate has multiple through slots that correspond one-to-one with each of the second water inlet pipes. Each second water inlet pipe located inside the housing is a telescopic pipe. Each through slot is fitted onto the telescopic end of each second water inlet pipe and is fixedly connected to the telescopic end of each second water inlet pipe.

[0014] Preferably, the diameter of the telescopic end of each telescopic pipe is larger than the diameter of the first water inlet pipe, and the inlet of the first water inlet pipe is flush with the sealing layer.

[0015] Preferably, the telescopic end of each of the telescopic tubes is snapped into the first water inlet pipe.

[0016] Preferably, a telescopic guide cylinder is provided between the water tank and the top of the casing, the elastic element is sleeved on the outside of the telescopic guide cylinder, and the telescopic length of the telescopic guide cylinder is greater than or equal to the distance between the first water inlet pipe and the second water inlet pipe located on the water tank before sampling.

[0017] Preferably, the top of the housing is provided with a vertical fixing rod, and the fixing rod is provided with scale lines.

[0018] Preferably, a counterweight is provided on the outside of the casing.

[0019] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0020] The lake ecological environment monitoring and sampling device provided by this invention is a purely mechanical device. There are no electrical components in the device, so it can overcome the problem of the controller and solenoid valve being in a humid environment for a long time, thereby avoiding the instability of electrical performance, improving the safety of normal use of the equipment, avoiding the risk of equipment failure, and achieving normal sampling.

[0021] Before sampling, the piston plate inside the casing of the lake ecological environment monitoring sampling device provided by this invention is subjected to the gravity of the water tank, so that it always covers the outlet of the third water inlet pipe. When sampling is required, the lake ecological environment monitoring sampling device is placed vertically in the lake water area to be sampled. Since the outlet of the first water inlet pipe is always in contact with the sealing layer, water will not enter the first water inlet pipe before the target water level is reached. Instead, water will enter through the third water inlet pipe located at the bottom of the casing. The elastic modulus of the elastic element is the pressure value of water entering the third water inlet pipe. Therefore, water will not enter the casing through the third water inlet pipe before the target water level is reached, pushing the piston plate and push rod upward, thereby driving the water tank upward. When the elastic element is compressed to the maximum, multiple second water inlets correspond one-to-one with multiple first water inlets, so that external water enters the water tank through the first and second water inlets and is stored until the water tank is full, thus completing the sampling.

[0028] To make the above-mentioned objectives, features, and advantages of the embodiments of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The inventors discovered that when a sampling device using electrical components operates in a humid environment for extended periods, moisture from the air may seep into the internal components, particularly electrical components such as motors, circuit boards, switches, and terminals. If these components come into contact with moisture, short circuits, leakage, or other electrical faults may occur, affecting the stability of the sampling device and causing it to malfunction, thus impacting its long-term stable operation.

[0030] In view of this, the present invention provides a sampling device for monitoring the ecological environment of lakes. This sampling device does not use electrical components, which improves the stability of equipment use and avoids the risk of equipment failure.

[0031] like Figures 1-5 As shown, the present invention provides a lake ecological environment monitoring sampling device, comprising multiple water tanks 1 connected from bottom to top, a sealing layer 2 on the outer wall of the multiple water tanks 1, first water inlet pipes evenly spaced on the multiple water tanks 1, and a first one-way valve on each first water inlet pipe, and further comprising:

[0032] The housing 3 is located outside multiple water tanks 1, and the multiple water tanks 1 are slidably connected to the inner wall of the housing 3 along the vertical direction. Multiple second water inlet pipes corresponding to the water tanks 1 are provided on the housing 3, and the distance between two adjacent second water inlet pipes is equal. Each second water inlet pipe is provided with a second one-way valve. A third water inlet pipe is provided at the bottom of the housing 3, and a third one-way valve is provided inside the third water inlet pipe.

[0033] Piston plate 4 is located inside housing 3 between the third water inlet pipe and water tank 1, and is slidably connected to the inner wall of housing 3. Piston plate 4 is connected to water tank 1 by a connecting rod.

[0034] Elastic element 5 connects the top of water tank 1 and housing 3.

[0035] Before sampling, the external water needs to overcome the elastic force of the elastic element 5 so that the second water inlet pipe always abuts against the sealing layer 2 before reaching the specified sampling depth; when sampling reaches the specified depth, the elastic element 5 is compressed, and the piston plate 4 pushes the water tank 1 upward through the connector so that the multiple second water inlet pipes correspond one-to-one with the multiple first water inlet pipes and are connected.

[0036] When using:

[0037] Before sampling, the piston plate 4 inside the housing 3 of the present invention is subjected to the gravity of the water tank 1, so that it always covers the outlet of the third water inlet pipe. When sampling is required, the lake ecological environment monitoring sampling device is placed vertically in the lake water area to be sampled. Since the outlet of the first water inlet pipe is always in contact with the sealing layer 2, water will not enter the first water inlet pipe before the target water level is reached. Instead, water will enter the housing 1 through the third water inlet pipe located at the bottom of the housing 3. The elastic modulus of the elastic element 5 is the pressure value of water entering the third water inlet pipe. Therefore, water will not enter the housing 1 through the third water inlet pipe before the target water level is reached, pushing the piston plate 4 and the connecting rod to move upward, thereby driving the water tank 1 to move upward. When the elastic element 5 is compressed to the maximum, multiple second water inlets correspond one-to-one with multiple first water inlets, so that external water enters the water tank 1 through the first water inlet pipe and the second water inlet pipe for storage until the water tank 1 is fully stored and the sampling is completed.

[0038] Specifically, the present invention provides an alignment component 6, which further enables precise water sampling. The alignment component 6 is used to ensure that each first water inlet pipe and each second water inlet pipe located on the water storage tank 1 are aligned during sampling. The alignment component 6 includes two push rods 6-1 and two telescopic rods 6-2. The two push rods 6-1 are obliquely and symmetrically arranged on both sides of the connecting rod, and the two telescopic rods 6-2 are symmetrically arranged horizontally on both sides of the connecting rod. The top end of each push rod 6-1 is hinged to the piston plate 4, and the bottom end of each push rod 6-1 is hinged to the telescopic end of the telescopic rod 6-2. The fixed end of each telescopic rod 6-2 is connected to the connecting rod. The housing 3 is symmetrically provided with through holes for the telescopic ends of the telescopic rods 6-2 to pass through. The housing 3 is sealed with a sealing shell that communicates with each through hole. When the push rod 6-1 moves upward under the action of the piston plate 4, it pushes the telescopic ends of the two telescopic rods 6-2 into the sealing shell through the through holes, so that the multiple second water inlet pipes correspond one-to-one with the multiple first water inlet pipes and are connected.

[0039] When using:

[0040] Before sampling, the piston plate 4 inside the housing 3 of the present invention is subjected to the gravity of the water tank 1, ensuring it always covers the outlet of the third inlet pipe. When sampling is required, the lake ecological environment monitoring sampling device is vertically placed in the lake area to be sampled. Since the outlet of the first inlet pipe is always in contact with the sealing layer 2, water will not enter the first inlet pipe before the target water level is reached. Instead, water will enter through the third inlet pipe located at the bottom of the housing 3. The elastic modulus of the elastic element 5 is equal to the pressure value of the water entering the third inlet pipe, thus ensuring the target water level is reached. Before the position is reached, water will not enter the housing 3 through the third water inlet pipe, pushing the piston plate 4 and connecting rod upward, which in turn drives the water tank 1 upward. The upward movement of the piston plate 4 causes the push rod 6-1 to change angle, which in turn pushes the telescopic end of the telescopic rod 6-2, which is hinged to it, to pass through the outlet hole in the horizontal direction and enter the sealed shell. Meanwhile, the elastic element 5 of the piston plate 4 is compressed to the maximum extent. Thus, both ensure that the multiple second water inlet pipes correspond one-to-one with the multiple first water inlet pipes. As a result, the external water enters the water tank 1 through the first water inlet pipe and the second water inlet pipe and is stored until the water tank 1 is fully sampled.

[0041] Specifically, the telescopic ends of each telescopic rod 6-2 are engaged with each sealing shell, which is a connection method to overcome the external thrust of water.

[0042] Specifically, in order to further realize that multiple second water inlet pipes correspond one-to-one with and are connected to multiple first water inlet pipes, the outer wall of the telescopic end of the telescopic rod 6-2 is provided with a first rack 7 in the horizontal direction. The inner wall of the housing 3 is rotatably connected with a drive gear 8 that meshes with the first rack 7. The drive gear 8 is also meshed with a second rack 9 that is parallel to the first rack 7. A push plate 10 is fixed to the top of the second rack 9. The top of the push plate 10 is slidably connected to the inner wall of the housing 3 in the horizontal direction. Multiple through slots are opened on the push plate 10 that correspond one-to-one with each of the second water inlet pipes. Each second water inlet pipe located inside the housing 3 is a telescopic pipe. Each through slot is sleeved on the telescopic end of each second water inlet pipe and is fixedly connected to the telescopic end of each second water inlet pipe.

[0043] When using:

[0044] When the piston plate 4 moves upward, causing the push rod 6-1 to change angle, and thus pushing the telescopic end of the telescopic rod 6-2, which is hinged to it, to pass through the through hole in the horizontal direction and enter the sealed shell, the first rack 7 located on the outer wall of the telescopic end of the telescopic rod 6-2 drives the drive gear 8 to rotate, which in turn drives the second rack 9, which meshes with the drive gear 8, to rotate in the opposite direction, which in turn drives the push plate 10, which is connected to the second rack 9 and moves in the horizontal direction, to move horizontally. The horizontal movement of the push plate 10 drives the telescopic ends of each second water inlet pipe to connect to the first water inlet pipe, thus completing accurate sampling.

[0045] Specifically, the diameter of the telescopic end of each telescopic tube is larger than the diameter of the first water inlet pipe. The inlet of the first water inlet pipe is flush with the sealing layer 2. When the push plate 10 moves horizontally, the telescopic ends of each telescopic tube are precisely connected with the first water inlet pipe, thereby achieving precise sampling.

[0046] Specifically, the telescopic ends of each telescopic tube are snapped into the corresponding first water inlet pipe.

[0047] Specifically, a telescopic guide cylinder 12 is provided between the top of the water tank 1 and the housing 3. The elastic element 5 is sleeved on the outside of the telescopic guide cylinder 12, and the telescopic length of the telescopic guide cylinder 12 is greater than or equal to the distance between the first water inlet pipe and the second water inlet pipe located on the water tank 1 before sampling. The purpose is to realize that multiple second water inlet pipes correspond one-to-one with multiple first water inlet pipes and are connected for accurate sampling.

[0048] Specifically, the top of the housing 3 is provided with a vertical fixing rod 11, and the fixing rod 11 is provided with scale lines for accurately determining the sampling depth.

[0049] Specifically, a counterweight 13 is provided on the outside of the housing 3 to ensure that the sampling device is vertical.

[0050] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
