It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] refer to Figures 1 to 8 A water environment heavy metal pollution monitoring device includes a submersible rod 1, a guide plate 2, a drive component 3, a sampling component 4 and a regulating component 5; the submersible rod 1 is configured as an electric telescopic rod, the annular outer wall of the guide plate 2 is fixed to the output end of the submersible rod 1, and the inner wall of the guide plate 2 is provided with an extension portion inwardly, the drive component 3 is arranged on the guide plate 2, the sampling components 4 are configured with two, which are distributed circumferentially on the drive component 3, and the regulating components 5 are configured with at least two, which are arranged between the sampling component 4 and the guide plate 2.

[0021] For details, please refer to Figure 1 The submersible rod 1 can send the guide disk 2 into waters of different depths. The driving component 3 can drive the two sampling components 4 to rotate, so as to sample the samples within the depth range of the guide disk 2 in a smaller depth range and multiple times. The regulating component 5 cooperates with the sampling component 4 to ensure that the sampling component 4 can sample when the water flow is stable, thereby ensuring that sampling within a smaller depth range is not affected by waters of other depths, and the monitoring results at the specific depth are more accurate.

[0022] As a preferred embodiment, an annular groove 21 and an annular groove 22 are formed on one side of the guide plate 2. The cross-section of the annular groove 21 is rectangular, the cross-section of the annular groove 22 is T-shaped, and the diameter of the annular groove 21 is smaller than the diameter of the annular groove 22.

[0023] As a preferred embodiment, the drive assembly 3 includes a servo motor 31, an annular connecting frame 32, an inner gear ring 33 and a gear 34; the servo motor 31 is fixedly installed on the extension portion, and the servo motor 31 is electrically connected to an external control unit, the annular connecting frame 32 is slidably arranged in the annular groove 21, the inner gear ring 33 is coaxially fixed on the end of the annular connecting frame 32 away from the guide plate 2, the gear 34 is fixed on the output shaft of the servo motor 31, and the gear 34 is meshed with the inner gear ring 33.

[0024] For explanation, see Figure 1 The submersible rod 1 positions the guide plate 2 in a water area with a relatively large depth range, and the servo motor 31 drives the gear 34 to rotate, thereby driving the inner gear ring 33 to rotate.

[0025] As a preferred embodiment, please refer to Figure 2 The sampling assembly 4 includes an outer tube 41, a sealing plate 44, a sampling tube 42 and an opening and closing component 43; the outer tube 41 is fixed on the outer wall of the annular connecting frame 32, and the axis of the outer tube 41 is parallel to the annular connecting frame 32, the sealing plate 44 is fixed to the end of the outer tube 41 away from the guide plate 2, and a liquid inlet hole is opened in the center of the sealing plate 44, the sampling tube 42 is rotatably arranged in the outer tube 41, and an escape space is arranged between the sampling tube 42 and the sealing plate 44, and the opening and closing component 43 is arranged in the escape space.

[0026] That is to say, the rotation of the inner gear ring 33 will drive the two outer cylinders 41 and the sampling cylinder 42 to rotate synchronously, so that the sampling cylinder 42 can perform multiple sampling operations at different water depths on the formed circular track.

[0027] As a preferred embodiment, the opening and closing component 43 includes a guide seat 431, a rotating ring 432, a return spring 433, a sealing plate 434 and a connecting arm 435; the guide seat 431 is provided with two on the circumference, both of which are fixed on the sealing plate 44 close to the guide disk 2, the rotating ring 432 is fixed on the end of the sampling tube 42 close to the sealing plate 44, a plurality of arc guide grooves are provided on the circumference of the rotating ring 432, the guide seat 431 is slidably arranged in the arc guide groove, a plurality of return springs 433 are configured, respectively connected between the guide seat 431 and the arc guide groove, a plurality of sealing plates 434 are distributed on the circumference, the sealing plate 434 has at least two eccentric ends, one of which is rotatably arranged on the sealing plate 44 by rotating shaft one, one end of the connecting arm 435 is rotatably arranged on the rotating ring 432 by rotating shaft two, and the other end is rotatably arranged on the other eccentric end of the sealing plate 434 by rotating shaft three.

[0028] For details, please refer to Figure 3 When the sampling tube 42 rotates in the outer tube 41, it will drive the rotating ring 432 to rotate synchronously. The rotating ring 432 can push the sealing plate 434 to rotate through the connecting arm 435, so that the opening and closing of the multiple sealing plates 434 can open or block the liquid inlet hole of the sealing plate 44, so as to switch between the sampling and waiting for sampling states. That is to say, the multiple sealing plates 434 can block the port of the sampling tube 42 in the gathered state, that is, the position adjustment state. Similarly, the multiple sealing plates 434 can open the port of the sampling tube 42 in the scattered state, that is, the sampling state.

[0029] As a preferred embodiment, the regulating component 5 includes a ratchet 51, a T-shaped block 52, a connecting column 53 and a pawl 54; the ratchet 51 is fixed on the outer wall of the sampling tube 42, the T-shaped block 52 is slidably arranged in the annular groove 22, the outer periphery of the T-shaped block 52 is covered with a rubber pad 521, the connecting column 53 is fixed on the T-shaped block 52, the pawl 54 is rotatably arranged on the outer wall of the connecting column 53, and the pawl 54 is in line contact with the ratchet 51.

[0030] It should be explained that when the T-shaped block 52 slides along the second annular groove 22 , it needs to overcome the friction between the rubber pad 521 and the second annular groove 22 .

[0031] The friction force between the rubber pad 521 and the annular groove 22 is greater than the elastic force of the return spring 433 .

[0032] That is, when the sampling tube 42 rotates in the outer tube 41 , the resistance of the return spring 433 cannot push the pawl 54 to move.

[0033] As a preferred embodiment, an arc groove 531 is opened on the outer wall of the connecting column 53, a slider 541 is fixed in the pawl 54, and the slider 541 is slidably set in the arc groove 531. A compression spring 55 is connected between the slider 541 and one side of the arc groove 531. This is a conventional coupling between ratchet pawls, which is well known to people in this field and will not be elaborated here.

[0034] Specifically, see Figures 5 to 7 When the annular connecting frame 32 drives the two outer cylinders 41 to rotate circumferentially, the sampling cylinder 42 will drive the ratchet 51 to rotate synchronously, but the pawl 54 will prevent the ratchet 51 from rotating circumferentially, so that the ratchet 51 and the sampling cylinder 42 rotate in the outer cylinder 41 under the damping force of the pawl 54, and the sampling cylinder 42 will drive the rotating ring 432 to rotate synchronously, and the rotating ring 432 can push the blocking plate 434 to rotate through the connecting arm 435, so that the multiple blocking plates 434 block the liquid inlet hole. At this time, the arc guide groove of the rotating ring 432 is just limited by the guide seat 431, and then the sampling cylinder 42 will remain relatively stationary with the outer cylinder 41 At the same time, the ratchet 51 and the pawl 54 remain relatively still, and then the ratchet 51 pushes the T-shaped block 52 to move circumferentially by meshing with the pawl 54, so that the sampling tube 42 reaches another water depth. During this movement, the sampling tube 42 remains in a closed state. When it reaches another water depth, the servo motor 31 controls it to stop driving through the external control unit, and the damping force of the pawl 54 on the ratchet 51 disappears. Under the reset force of the reset spring 433, the rotating ring 432 will drive the sampling tube 42 to rotate in the opposite direction, and the multiple sealing plates 434 will expand, and the liquid inlet hole will be in an open state, so as to sample the water at this depth.

[0035] To summarize, the sampling tube 42 is always kept closed during the depth adjustment and sampling process, and sampling is performed after the depth adjustment is completed. That is to say, the sampling tube 42 can perform sampling under stable water flow conditions to prevent the sampling tube 42 from stirring the water area during movement, causing mixing of water areas at different depths, thereby ensuring a one-to-one correspondence between the samples taken and the corresponding depths, thereby improving the accuracy of the data.

[0036] Please note that Figure 8 A sampling chamber is provided at the front end of the sampling tube 42, and a plurality of sample storage bins are linearly provided at the rear end of the sampling chamber, and partitions are detachably installed between the plurality of sample storage bins, the sampling chamber is connected to each sample storage bin through a flow channel, and a micro liquid pump is installed in each flow channel, and the plurality of micro liquid pumps are electrically connected to an external control unit respectively; Specifically, if the sampling depth is from high to low, when the liquid inlet is in an open state, water will enter the sampling chamber. After the sampling is completed, the liquid inlet is closed, and the sampling tube 42 is moving downward. The external control unit controls the micro liquid pump in the flow channel connected to the rightmost sample storage bin to start, and the sample in the sampling chamber is drawn into the rightmost sample storage bin. Similarly, when the sampling tube 42 moves down to the next sampling depth, the micro liquid pump corresponding to an adjacent sample storage bin draws the sample in the sampling chamber into the sample storage bin, and so on. Multiple sample storage bins can independently store samples of different depths for subsequent monitoring one by one.

[0037] It should also be explained that the two sampling barrels 42 can take samples synchronously. Specifically, when the two sampling barrels 42 move to the same depth, they can synchronously sample the water area at this depth. That is to say, within the same time period, the two sampling barrels 42 can synchronously sample the water area at the same depth, so as to facilitate comparison between monitoring results, avoid data uniformity, and make monitoring data more accurate and reliable.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
