[0002] The sampling device is widely applied to the monitoring of water ecological environment, benthic microorganisms and water environment of rivers, lakes, oceans, reservoirs and the like, and is an important tool for studying water pollution trends and ecological influences.

[0041] Reference Figures 1 to 7 The following are several embodiments of the sampling device of this utility model suitable for collecting shallow water sediments.

[0042] like Figures 1 to 3 As shown, the sampling device for shallow water sediment collection according to this embodiment of the present invention includes a sampling tube 100, a handheld component 200, a sensor assembly 300, and a display assembly 400. A one-way valve 110 is provided on the sampling tube 100; a sampling port 120 is provided at the bottom of the sampling tube 100, and a sampling chamber 130 is provided inside the sampling tube 100, with the sampling port 120 communicating with the sampling chamber 130; the one-way valve 110 is located at the sampling port 120, and the conduction direction of the one-way valve 110 is from the sampling port 120 to the sampling chamber 130; the handheld component 200 is connected to the sampling tube 100; the sensor assembly 300 includes at least one of a temperature sensor and a pressure sensor; the sensor assembly 300 is located on the sampling tube 100; the display assembly 400 is located on the handheld component 200 and is signal-connected to the sensor assembly 300; the display assembly 400 is used to display at least data information.

[0043] By holding the handheld component 200 and inserting the sampling tube 100 into the water, underwater sediment enters the sampling chamber 130 through the sampling port 120. Removing the sampling tube 100 completes the sediment collection process. The handheld component 200 is easy to grip, and the one-way valve 110 allows sediment to enter the sampling chamber 130 through the sampling port 120 while preventing sediment from flowing out of the sampling port 120. The sensor assembly 300 can detect at least one of the water temperature and depth, and transmit the detected data to the display assembly 400, which displays the data acquired by the sensor assembly 300. Through the sensor assembly 300 and the display assembly 400, the user can monitor the underwater environment in real time.

[0044] The temperature sensor can obtain the temperature of the water body, and the pressure sensor can obtain the water pressure and calculate the water depth where the pressure sensor is located. In order to improve the accuracy of the data obtained by the sensor assembly 300, the sensor assembly 300 is set at the end of the sampling tube 100 near the sampling port 120.

[0045] The sampling devices of related technologies are easily affected by water disturbance during the sampling process, which may lead to sample contamination or structural damage. In addition, they lack real-time data monitoring capabilities, making it difficult to meet the scientific research requirements for accurate recording of sampling parameters.

[0046] This application enables real-time monitoring of environmental parameters (such as water temperature and depth) of the water body during sampling through a sampling tube 100, a handheld device 200, a sensor assembly 300, and a display assembly 400. The parameters are displayed on the display assembly 400 for easy and accurate recording. The underwater conditions can be observed in real time through the display assembly 400, and the sampling tube 100 can be inserted into the sediment after the values ​​displayed on the display assembly 400 have stabilized. This utility model embodiment is lightweight, portable, and easy to operate.

[0047] The sensor assembly 300 of this embodiment includes a temperature sensor and a pressure sensor, which facilitates the detection of water temperature and depth.

[0048] In some embodiments, the handheld component 200 is cylindrical, with one end connected to the top of the sampling tube 100 and the other end used to mount the display component 400.

[0049] The columnar handheld component 200 reduces the size of the sampling device while allowing for hand operation, making it easy to carry. One end of the handheld component 200 is connected to the top of the sampling tube 100, and the other end is used to install the display component 400. That is, the sampling tube 100 is located at the bottom of the handheld component 200, and the display component 400 is located at the top of the handheld component 200. This arrangement makes it convenient for users to view the data displayed by the display component 400 during the collection process, and it can also maximize the distance between the display component 400 and the water body, reducing the risk of the display component 400 accidentally getting water in.

[0050] In this embodiment, the handheld component 200 is 80 cm long and has an outer diameter of 5 cm; the display component 400 may include a housing 420, and the housing 420 and the handheld component 200 are connected by threads for easy assembly and disassembly.

[0051] In some embodiments, such as Figure 4 As shown, the display assembly 400 also includes a signal receiver and a display screen 410; the signal receiver and the display screen 410 are electrically connected, and the signal receiver is used to receive signals transmitted by the sensor assembly 300.

[0052] The signal receiver receives signals transmitted from the sensor assembly 300 and transmits the received signals to the display screen 410. Data such as water temperature and water pressure can be displayed on the display screen 410. Typically, the signal receiver is a WiFi receiver. The signal receiver is housed within the housing 420, and the display screen 410 is located on top of the housing 420. The display assembly 400 also includes a memory card for storing data and a battery for power.

[0053] The display component 400 also includes a power switch 430, a storage button 440, a water pressure switching button 450, and a water temperature switching button 460. These buttons are electrically connected to the display screen 410. The power switch 430 controls the display screen 410 to turn on and off. Pressing the storage button 440 stores data in a memory card. Pressing the water pressure switching button 450 switches the data displayed on the display screen 410 to water pressure data. Pressing the water temperature switching button 460 switches the data displayed on the display screen 410 to water temperature data. The display screen 410 is 10 cm long, 5 cm wide, and 2 cm high. The signal receiver receives signals transmitted from the sensor component 300. The operating state of the display screen 410 can be switched using the power switch 430, storage button 440, and water pressure / temperature switching button 460.

[0054] In some embodiments, such as Figure 1 and Figure 5 As shown, the end of the handheld component 200 is provided with a connecting part 210, which is used to connect the sampling tube 100. The handheld component 200 is connected through the connecting part 210, so that the handheld component 200 and the sampling tube 100 are connected to form a tube body, which is convenient for operation. The outer wall of the connecting part 210 is provided with an exhaust hole 211. When the connecting part 210 is connected to the sampling tube 100, the exhaust hole 211 is connected to the sampling chamber 130. This prevents the samples such as sediment from failing to enter the sampling chamber 130 smoothly due to the internal pressure during the process of the sampling tube 100 sinking underwater.

[0055] In some embodiments, such as Figure 1 As shown, the display component 400 and the handheld component 200 are threadedly connected; the threaded connection facilitates the disassembly and assembly of the display component 400 and the handheld component 200.

[0056] The handheld component 200 and the display component 400 are connected by threads. Specifically, the top of the handheld component 200 is provided with a first external thread, and the outer shell 420 of the display component 400 is provided with a connecting block. The connecting block is provided with a first internal thread. The connection between the handheld component 200 and the display component 400 is achieved through the first external thread and the first internal thread.

[0057] The connecting part 210 is generally truncated cone-shaped, with a diameter of 5 cm on the upper surface and 10 cm on the lower surface, and a wall thickness of 3 mm. The exhaust hole 211 is 3 cm long and 2 cm wide, and 8 exhaust holes 211 can be provided. Of course, in other embodiments, 5, 6 or 7 exhaust holes 211 can be provided. This utility model embodiment does not impose a special limitation on the number of exhaust holes 211, as long as the exhaust holes 211 can play the role of venting air.

[0058] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the sampling tube 100 includes a tube body 140 and a fitting shell 150 located at the bottom of the tube body 140. The tube body 140 and the fitting shell 150 are threaded together for easy assembly and disassembly. The fitting shell 150 has a sampling port 120, and a one-way valve 110 and a sensor assembly 300 are disposed on the fitting shell 150. The fitting shell 150 can be removed before the sediment sample inside the tube body 140 is extracted, making it easy to remove the sediment sample inside the tube body 140.

[0059] In some embodiments, the handheld component 200 and the tube body 140 are threaded together to facilitate disassembly and assembly between the handheld component 200 and the tube body 140. Specifically, the connecting portion 210 at the bottom of the handheld component 200 is provided with a second internal thread, and the top of the sampling tube 100 is provided with a second external thread. The connection between the handheld component 200 and the sampling tube 100 is realized through the cooperation of the second internal thread and the second external thread.

[0060] like Figure 2 As shown, the accessory housing 150 is made of stainless steel. One end of the accessory housing 150 is a sampling port 120, and the other end is connected to the tube body 140 via threads. Specifically, the bottom of the sampling tube 100 is provided with a third internal thread, and the top of the accessory housing 150 is provided with a third external thread. The accessory housing 150 and the tube body 140 are connected through the third internal and third external threads. A signal transmitter is also installed inside the accessory housing 150. The signal transmitter is used to transmit signals to the signal receiver to transmit the data detected by the sensor assembly 300 to the display assembly 400, thereby realizing real-time monitoring of water temperature and depth. The accessory housing 150 has a height of 5 cm, an outer diameter of 15 cm, and a sampling port 120 diameter of 9 cm. The tube body 140 is made of high-strength glass. To improve the rigidity of the tube body 140, stainless steel wire can be embedded within the high-strength glass. The signal transmitter can be a microprocessor, and it can transmit signals to the display assembly 400 via WiFi signal transmission.

[0061] In some embodiments, such as Figure 2 and Figure 6 As shown, the one-way valve 110 includes a one-way flap 111 and a limiting member 160; the one-way flap 111 is rotatably connected to the accessory housing 150, and the limiting member 160 is disposed at the sampling port 120. The limiting member 160 is used to restrict the one-way flap 111 from rotating toward the sampling port 120.

[0062] As the sampling tube 100 moves underwater, it is subjected to water pressure, causing the one-way valve 111 to rotate towards the inside of the accessory housing 150, opening the sampling port 120 and allowing underwater sediment to enter the sampling chamber 130. When the sampling tube 100 is taken out from underwater, i.e., when the sampling tube 100 moves towards the water surface, it is subjected to the gravity of the sediment, causing the accessory housing 150 to rotate towards the sampling port 120 until it comes into contact with the limiting member 160, closing the sampling port 120 and reducing the risk of sediment samples flowing back out of the sampling port 120 due to pressure.

[0063] One-way lobe 111 is an acrylic one-way partition; there are two one-way lobes 111, and the two one-way lobes 111 are respectively connected to the accessory housing 150 by hinges. The limiting member 160 is a stainless steel limiting strip; by limiting the one-way lobe 111, it can only complete the upward one-way rotation and cannot complete the downward rotation, which prevents the sample from flowing back under pressure when the sampling tube 100 is pulled out.

[0064] In some embodiments, such as Figure 1 and Figure 3 As shown, the sampling tube 100 also includes an inner tube 170, and a sampling cavity 130 is formed inside the inner tube 170; the tube body 140 is sleeved outside the inner tube 170, and the inner tube 170 is used to protect the integrity of the sample. The inner tube 170 is 80 cm long, has an outer diameter of 8 cm, and an inner diameter of 7 cm, and the inner tube 170 is a transparent acrylic sleeve.

[0065] In some embodiments, such as Figure 7 As shown, the sampling device also includes a push rod 500, which is used to penetrate into the sampling chamber 130 to push out the sediment inside the sampling chamber 130. The push rod 500 facilitates the removal of sediment from the sampling chamber 130, preventing sediment residue from remaining inside. The length of the push rod 500 is greater than the length of the tube body 140, allowing the push rod 500 to penetrate the tube body 140 along its length. The push rod 500 is 90 cm long, has an outer diameter of 5 cm, and a wall thickness of 3 mm. A push handle is provided at the end of the push rod 500 for easy operation. The push rod 500 has a diameter of 85 cm and a thickness of 2 cm.

[0066] In some embodiments, a piston 510 is provided on the push rod 500. The piston 510 is used to abut against the inner wall of the sampling chamber 130. Generally, the sampling chamber 130 is cylindrical. Through the action of the piston 510 and the interior of the sampling chamber 130, the deposits inside the sampling chamber 130 can be completely removed from the sampling chamber 130, reducing the probability of deposits adhering to the inner wall of the sampling chamber 130. Generally, the piston 510 is made of hard rubber material, and the width of the piston 510 can be equal to the inner diameter of the sampling chamber 130.

[0067] Initially, check if the display component 400 has sufficient power and if the signal transmitter inside the accessory housing 150 is functioning properly. Then, thread the display component 400 to the handheld device 200, and then thread the sampling tube 100 to the accessory housing 150. Next, thread the handheld device 200 to the sampling tube 100. Then, insert the sampling tube 100 into the water. After the accessory housing 150 touches the bottom, observe the value on the display screen 410. After the value on the display screen 410 gradually stabilizes, click the storage button 440 to record the data. Then, insert the sampling tube 100 into the sediment, allowing the sediment to enter the sampling chamber 130 for sampling. After sampling is completed, use the handheld device 200 to pull the sampling tube 100 out of the water and place the sampling device vertically to allow the water in the sample to flow out of the sampling port 120. Then, remove the display component 400, handheld device 200, and accessory housing 150, and insert the push rod 500 into the sampling chamber 130 to push out the sediment sample.

[0068] This invention enables convenient carrying and operation of the sampling device during operation, and allows for the display and recording of sampling depth and water temperature parameters. It solves the problems of traditional columnar sampling devices (such as gravity samplers and vibration samplers), which are complex to operate, have uncontrollable sampling depth, are easily affected by water disturbance during sampling leading to sample contamination or structural damage, and lack real-time data monitoring functions.

[0069] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
