[0002] In the actual process of water quality testing in large bodies of water, preliminary visual screening is the lowest-cost and fastest preliminary judgment step. By visually identifying whether there are significant abnormalities in the water quality, it can be determined whether to initiate subsequent in-depth laboratory testing, effectively avoiding the waste of resources caused by blind testing.

The insufficient sample collection leads to a significant reduction in the accuracy and identification of visual observation. Carrying two different sampling devices for diverse sampling methods affects convenience, and frequent switching between devices can easily lead to operational errors. Combining the two sampling methods can increase the size of the sampling equipment, which also affects convenience and can increase the disturbance to the water body during sampling, making it difficult to guarantee sampling accuracy.

Detailed Implementation

[0017] 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 only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-10 This invention provides a technical solution: a cruise-type large-area water quality testing device, comprising: a sampling box 1, a partition plate 3, and sampling tubes 5; the sampling box 1 is provided with a sampling chamber 2 for coarse testing; the partition plate 3 is slidably connected to the sampling box 1 and can divide the sampling chamber 2 into multiple sampling chambers 4 for fine testing; a plurality of sampling tubes 5 are set to the same number as the sampling chambers 4, and are all installed at the bottom of the sampling box 1; the top ends of the plurality of sampling tubes 5 are respectively connected to the sampling chambers 4, and the bottom ends of the plurality of sampling tubes 5 extend to the outside of the sampling box 1; a control unit is provided on the outside of the sampling box 1, the control unit is configured to control the opening and closing of the sampling tubes 5 according to the working state of the partition plate 3; during coarse testing, the control unit causes the plurality of sampling tubes 5 to open synchronously; during fine testing, the control unit causes the plurality of sampling tubes 5 to open sequentially.

[0019] Staff members patrolled the target waters in a boat carrying a detection device. When they sensed a potential water quality anomaly in a certain area, they lowered the detection device below the water surface using a rope. Initially, a preliminary sample was taken. The control unit opened the bottom ends of multiple sampling tubes 5, allowing water to quickly fill the sampling chamber 2 through the tubes. At this time, the partition plate 3 was in position... Figure 1 As shown in the diagram, the sampling box 1 is then returned to the ship. It should be noted that the top of the sampling box 1 is made of transparent material, allowing staff to directly observe the water quality in sampling chamber 2 from the top for preliminary testing. If the water quality is normal, the control unit can then open the sampling tube 5 to drain the water from sampling chamber 2, and then introduce cleaning water through the sampling tube 5 into sampling chamber 2 to clean the sampling box 1 and prevent sample residue. If the water quality is abnormal and further testing is required, the partition plate 3 is pushed upwards from the bottom of the sampling box 1. Figure 2At the indicated location, sampling chamber 2 is divided into multiple sampling chambers 4. Sampling box 1 is then lowered below the water surface using ropes. After reaching the designated depth, the control unit opens one sampling tube 5, allowing water samples to enter sampling chamber 4 for fine sampling. After sampling, the control unit closes the sampling tube 5. The sampling process is repeated, lowering sampling box 1 to the next depth. After multiple samplings and reaching the required sample quantity, sampling box 1 is retrieved onto the boat, and the samples are sent for testing. The invention utilizes a sampling box 1 and a sampling chamber 2. The sampling chamber 2 has a large volume, making it suitable for coarse sampling and facilitating coarse water quality testing. Simultaneously, the partition plate 3 divides the sampling chamber 2 into multiple smaller sampling chambers 4, suitable for small-volume, multiple sampling, facilitating fine water quality testing. The sampling chambers 4 are contained within the sampling chamber 2, avoiding increasing the volume of the sampling box 1, making it easy to carry, and reducing disturbance to the water body when the sampling box moves downwards, thus improving sample accuracy.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, the sampling box 1 includes a box body 6 and a top cover 7; the box body 6 is hollow with an open top; the top cover 7 is installed on the top of the box body 6 and is detachably fixed to the box body 6; when the sampling box 1 needs to be cleaned, the top cover 7 is opened, the control unit controls the sampling tube 5 to open, and the cleaning water can be poured directly from the top of the box body 6 and discharged from the bottom of the sampling tube 5, which facilitates the cleaning of the sampling box 1.

[0021] Specifically, such as Figure 3 As shown, the control unit includes several sealing blocks 8 and a drive mechanism for moving the sealing blocks 8; the number of sealing blocks 8 is the same as that of the sampling tube 5, and they are used to seal the sampling tube 5 respectively; during sampling, the drive mechanism drives the sealing blocks 8 to move downward, the bottom end of the sampling tube 5 opens, and water can enter the sampling chamber 1 2 or the sampling chamber 2 4 from the bottom end of the sampling tube 5; after sampling is completed, the drive mechanism drives the sealing blocks 8 to move upward again, and the bottom end of the sampling tube 5 closes.

[0022] Example 1: Specifically, the drive mechanism includes several linear drive components, the number of which is the same as the number of sealing blocks 8, and the output ends are respectively connected to the sealing blocks 8; the linear drive components are cylinders, electric cylinders, hydraulic cylinders, etc.

[0023] Example 2, specifically, as follows: Figures 3-6As shown, the drive mechanism includes a mounting plate 9, several slide rods 10, a cylindrical cam 11, a push block 13, a cylinder 15, and a drive block 16; the mounting plate 9 is located outside the sampling box 1 and can slide relative to the sampling box 1; the number of slide rods 10 is the same as the number of sealing blocks 8, and they are fixed to the sealing blocks 8 respectively; all slide rods 10 are elastically slidably connected to the mounting plate 9; a spring 25 for resetting is fitted on the slide rod 10; the cylindrical cam 11 is rotatably connected to the mounting plate 9, and a cam groove 12 is provided on its inner wall; the cam groove 1... The number of peaks in 2 is the same as the number of sealing blocks 8; push block 13 is located on the side of cylindrical cam 11 and is fixedly connected to drive rod 14 that can cooperate with cam groove 12; cylinder 15 is configured to drive push block 13 to reciprocate; a locking element is provided between push block 13 and mounting plate 9, the locking element is configured to fix push block 13 and mounting plate 9 relative to each other during coarse inspection, and to slide push block 13 and mounting plate 9 relative to each other during fine inspection; drive block 16 is fixedly installed on the rotating shaft of cylindrical cam 11 and can drive slide rod 10 to slide relative to mounting plate 9.

[0024] Under the action of the locking mechanism, during coarse sampling, the push block 13 is relatively fixed to the mounting plate 9; during sampling, the cylinder 15 drives the push block 13 to move downward, and the push block 13 drives the mounting plate 9 to move downward through the locking mechanism. The mounting plate 9 drives several sliding rods 10 and several sealing blocks 8 to move downward simultaneously, so that multiple sampling tubes 5 open at the same time. Water quickly fills the sampling chamber 2 through multiple sampling tubes 5, improving the efficiency of coarse sampling; during fine sampling, the partition plate 3 moves upward to... Figure 2 In the indicated state, the locking mechanism stops working, and the mounting plate 9 is fixed relative to the sampling box 1. The push block 13 can move relative to the mounting plate 9. When the cylinder 15 drives the push block 13 to move downward, the push block 13, in conjunction with the drive rod 14, drives the cylindrical cam 11 to rotate. The cylindrical cam 11 drives the drive block 16 to rotate synchronously. When the drive block 16 rotates, the inclined surface 2 at its end can press the guide rod 26 fixed on the slide rod 10, causing the guide rod 26 to drive the slide rod 10 and the sealing block 8 to move downward synchronously, and the sampling tube 5 opens. (Reference) Figure 5 and Figure 6The following explanation uses an example where the partition plate 3 is set in a "+" shape, four sampling chambers 4, four sampling tubes 5, four sealing blocks 8, and four cam grooves 12 crests. The cylinder 15 drives the push block 13 and the drive rod 14 to reciprocate once in the vertical direction, the cylindrical cam 11 rotates 90°, and the drive block 16 drives the sealing block 8 to move downwards first, opening the sampling tube 5 for sampling. Then, the drive block 16 rotates until it disengages from the guide rod 26 on the slide rod 10, and the sealing block 8 moves upwards under the elastic force of the spring 25. Sampling is completed when the sampling tube 5 is closed. It should be noted that the shape of the partition plate 3 (i.e., the number of sampling chambers 4) can be designed according to the actual number of samplings. Compared with Embodiment 1, which sets the same number of linear drive components according to the number of sealing blocks 8, this embodiment only needs to rely on one cylinder 15 to achieve multiple samplings, reducing the number of electrical components and the failure rate of the detection device. Furthermore, the rotation direction of the cylindrical cam 11 and the drive block 16 is controllable, which can ensure the accuracy of the sampling sequence.

[0025] Specifically, such as Figure 4 and Figure 7 As shown, the locking component includes a fixing plate 17, a socket 18, a plug rod 19, and a push rod 20; the fixing plate 17 is fixed to the mounting plate 9; the socket 18 is opened on the push block 13; the plug rod 19 is elastically slidably connected to the fixing plate 17 and can be inserted into the socket 18; a spring 27 for resetting is fitted on the plug rod 19; the push rod 20 is fixed to the partition plate 3, and a slope 1 that can drive the plug rod 19 to move is opened at the bottom.

[0026] During the rough inspection, partition 3 was in... Figure 1 In the state shown, push rod 20 is in Figure 7 In the state shown, the insertion rod 19 is inserted into the insertion hole 18, the spring 27 is compressed, and the insertion rod 19 and the push block 13 are relatively fixed. Therefore, when the push block 13 moves downward, it can drive the mounting plate 9 to move downward synchronously through the insertion rod 19 and the fixing plate 17, and multiple sealing blocks 8 open simultaneously. During fine testing, the partition plate 3 moves upward to... Figure 2 In the state shown, the partition plate 3 drives the push rod 20 to move upward. After the push rod 20 and the insertion rod 19 are misaligned, the insertion rod 19 moves outward under the elastic force of the spring 27 and disengages from the insertion hole 18. At this time, when the push block 13 moves downward, it can drive the cylindrical cam 11 to rotate through the drive rod 14.

[0027] Specifically, such as Figure 3 and Figure 8 As shown, a bottom cover 21 is installed at the bottom of the sampling box 1; during coarse testing, the partition plate 3 is located inside the bottom cover 21; the bottom end of the sampling tube 5 passes through the bottom cover 21 and extends to the outside of the bottom cover 21; the cylinder 15 is fixed to the bottom cover 21; the bottom cover 21 is used to protect the partition plate 3.

[0028] Specifically, such as Figure 10 As shown, the mounting plate 9 is fixed with a sliding rod 22, which is slidably connected to the bottom cover 21; a limit block 23 is fixed on the side wall of the partition plate 3; during fine testing, the limit block 23 limits the sliding rod 22, making the mounting plate 9 and the sampling box 1 relatively fixed; during coarse testing, the limit block 23 is in a position where... Figure 10 As shown by the solid line, the limiting block 23 is directly below the slide bar 22, allowing the mounting plate 9 to move vertically. During fine inspection, the partition plate 3 moves the limiting block 23 upwards, and the limiting block 23 moves to... Figure 10 At the position indicated by the dashed line, the limiting block 23 limits the sliding rod 22. The sliding rod 22 is relatively fixed to the partition plate 3, and the mounting plate 9 and the sampling box 1 are in a relatively fixed state at this time, which can ensure the stability of sampling.

[0029] Specifically, such as Figure 8 and Figure 9 As shown, a second cylinder 24 for driving the partition plate 3 to move is fixed inside the bottom cover 21; the setting of the second cylinder 24 can improve the convenience of switching between coarse and fine detection.

[0030] The elastic sliding connection (installation) mentioned above refers to a structure in which parts can automatically return to their original position after sliding, including but not limited to the spring structure shown in the figure.
