[0040] The above are only optional embodiments of the present application and are not intended to limit the present application.

[0041] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings for the convenience of those skilled in the art to understand.

[0042] Embodiment 1:

[0043] See Figure 1 and Figure 2 , a visual dynamic monitoring system for safe operation of sea sand mining, including a visual monitoring terminal and a water sample collection device 1. A data collector 2 for receiving information data is provided on the water sample collection device 1. The water sample collection device 1 includes:

[0044] The mounting plate 4 is provided with a horizontal telescopic frame 5 and a turntable mechanism 6. A sampling tube 7 that cooperates with the horizontal telescopic frame 5 is wound on the turntable mechanism 6. One end of the sampling tube 7 is provided with a weight disk 8;

[0045] Wherein, scales 33 are provided on the sampling tube 7 and the horizontal telescopic frame 5. A distance sensor 25 for measuring the distance between the weight disk 8 and the water surface, and a displacement sensor 26 for measuring the displacement distance of the weight disk 8 are provided on the weight disk 8.

[0046] Specifically, the other end of the sampling tube 7 is connected to an airbag or a water pump 9. During actual use, one or more water sample collection devices can be fixedly or movably installed at the edge of the sand dredging ship. When water sample collection is required, by extending the horizontal telescopic frame 5, the sampling tube 7 at one end of the weight disk 8 is driven away from the ship's edge, and at the same time, the turntable mechanism 6 is driven to rotate, so that the sampling tube 7 is rotated out from the turntable mechanism 6. The extension length is observed through the scale 33 on the horizontal telescopic frame 5. When the target length is reached, the sampling tube 7 is further lowered by the weight disk 8 or by rotating the turntable mechanism 6. Whether the end of the weight disk 8 of the currently lowered sampling tube 7 reaches the water surface is observed through the scale on the sampling tube 7. In the case of reaching, the sampling tube 7 is further lowered according to the depth at which the water sample (i.e., water quality) is to be collected. After being lowered to the specified depth, the water sample is extracted by squeezing the airbag or by the water pump 9. Conversely, the sampling tube 7 is recovered by rotating the turntable mechanism in the reverse direction, and at the same time, the horizontal telescopic frame 5 is contracted, and the extracted depth and the sampling times are recorded in the data collector 2 (which can record by taking pictures or manually input data) for the operator to view and feedback to the visual monitoring terminal for the monitor to view. The visual monitoring terminal can be a computer, a mobile phone, a tablet or other monitoring terminals;

[0047] The data collector 2 receives the information data fed back by the distance sensor 25 and the displacement sensor 26. By providing the distance sensor 25 and the displacement sensor 26 on the weight disk 8, it is convenient for the operator to accurately know the depth of water quality sampling according to the information detected by the sensors, and it can also be used to judge the depth error range value compared with the sampling of the scale 33, so as to facilitate the operator to select different situations for water sample collection. The distance between the initial position of the weight disk 8 and the water surface is measured by the distance sensor, and the distance from the initial position of the weight disk 8 to the displacement point is measured by the displacement sensor, so as to obtain the depth of the weight disk 8 extending into the water, which can avoid the observation error caused by the operator through the scale 33 on the sampling tube 7 on the ship;

[0048] When the weight disk 8 reaches the water surface, due to the operator being on the ship, it is easy to form a visual error, resulting in an error in the depth at which the sampling tube 7 is lowered. Especially when the distance between the operator and the water surface is large, the probability of observation error is higher. Of course, it can also be applied when the distance between the operator and the water surface is small;

[0049] In this embodiment, the water sample collection device 1 is installed on the edge of the ship, and the length of the sampling tube 7 lowered and the length of the horizontally telescopic frame 5 extended are adjusted according to requirements to perform stratified water sample collection at different distances and depths from the hull, so as to accurately monitor the water samples at different water depths and different distances from the ship. The purpose of setting the weight disk 8 is to facilitate the vertical lowering of the sampling tube 7 and further ensure the precise control of the sampling point position.

[0050] In addition, it should be noted that the distance sensor 25 can also be replaced by a radar hydraulic sensor. The sensor is an existing one and will not be elaborated here too much.

[0051] Embodiment 2:

[0052] See Figure 2 , based on Embodiment 1, further and optionally, the horizontally telescopic frame 5 includes:

[0053] A first limit groove 14 arranged above the mounting plate 4. A second limit groove 15 is slidably connected in the first limit groove 14. A first sliding groove 16 is opened at the bottom of the first limit groove 14. A first limit sliding plate 17 is slidably connected in the first sliding groove 16. The upper end of the first limit sliding plate 17 is connected to the second limit groove 15, and the lower end of the first limit sliding plate 17 is connected to a horizontally telescopic mechanism 18, and the horizontally telescopic mechanism 18 is fixed on the mounting plate 4.

[0054] Specifically, the first limit groove 14 and the second limit groove 15 can be U-shaped grooves or T-shaped grooves. When they are T-shaped grooves, the sampling tube 7 can be limited, that is, its lowering or recovery from the first limit groove 14 and the second limit groove 15 is restricted. When they are U-shaped grooves, it cannot fully ensure the lowering or recovery of the sampling tube 7 from the first limit groove 14 and the second limit groove 15, but limiters such as arc-shaped parts can be set on them for limiting. Specifically, it can be selected according to the actual situation;

[0055] By controlling the expansion and contraction of the horizontally telescopic mechanism 18 to drive the first limit sliding plate 17 to slide in cooperation with the second limit groove 15, and the second limit groove 15 to slide in cooperation with the first limit groove 14. When the second limit groove 15 moves and the horizontally telescopic frame 5 extends, one end of the weight disk 8 pulls the sampling tube 7 to unfold. On the contrary, when the horizontally telescopic frame 5 contracts, the turntable mechanism 6 can be rotated to recover the sampling tube 7. The horizontally telescopic frame 5 is convenient to drive the first limit sliding plate 17 on the second limit groove 15 to move in the second limit groove 15 and the first sliding groove 16 through the expansion and contraction of the horizontally telescopic mechanism 18. When the second limit groove 15 slides out of the first limit groove 14, it is convenient to drive the sampling tube 7 forward. On the contrary, it prevents the sampling tube 7 from being completely retracted on the turntable mechanism 6, and the sampling tube 7 needs to be laid out again during the second sampling, which affects the sampling efficiency;

[0056] It should be noted that the horizontally telescopic mechanism 18 is a hydraulic telescopic mechanism. This mechanism is an existing technology and will not be elaborated here.

[0057] Example 3:

[0058] Referring to Figure 3 , based on the above embodiments, further and optionally, a second sliding groove 20 is formed on the opposite side of the first limiting groove 14, and a second limiting sliding plate 21 is slidably connected in the second sliding groove 20. One end of the second limiting sliding plate 21 is fixedly connected to the side wall of the second limiting groove 15.

[0059] Specifically, the second sliding groove 20 is provided on the first limiting groove 14, and the second limiting sliding plate 21 is slidably connected in the second sliding groove 20. The purpose is to strengthen the cooperation and fixation between the second limiting groove 15 and the first limiting groove 14, so as to facilitate the second limiting groove 15 to bear force and avoid easy fracture of the connection point, etc.

[0060] Example 4:

[0061] Referring to Figure 4 , based on the above embodiments, further and optionally, a limiting structure 19 is provided at one end of the second limiting groove 15. The limiting structure 19 includes:

[0062] Two support rods 22 fixed to the end of the second limiting groove 15, and two connecting rods 23 are spaced between the two support rods 22;

[0063] Among them, the two support rods 22 and the two connecting rods 23 enclose a square frame, and pulleys 24 are sleeved on each side of the square frame.

[0064] Specifically, the limiting structure 19 is conducive to limiting the sampling tube 7. The sampling tube 7 is limited by the square frame formed by the two support rods 22 and the two connecting rods 23, so that the sampling tube 7 can only move within the square frame. By providing the pulleys 24, it is beneficial to reduce the friction force when the sampling tube 7 is lowered and recovered.

[0065] Example 5:

[0066] Referring to Figure 5 , based on the above embodiments, further and optionally, the turntable mechanism 6 includes:

[0067] Two support plates 27 symmetrically arranged on the mounting plate 4, a rotating shaft 28 is rotatably connected between the two support plates 27, an I-shaped turntable 29 is sleeved on the rotating shaft 28, and a handle 30 is connected to one end of the rotating shaft 28.

[0068] Specifically, the handle 30 is provided to facilitate the application of force. By rotating the handle 30, the rotating shaft 28 is driven to rotate synchronously, thereby driving the I-shaped turntable 29 to rotate between the two support plates 27 to release or recover the sampling tube 7.

[0069] Further and optionally, threaded holes 31 are provided in the support plate 27 and the I-shaped turntable 29, and bolts 32 are threadedly connected in the threaded holes 31;

[0070] Wherein, by rotating the bolt 32, the support plate 27 is brought into abutment with or separated from the I-shaped turntable 29.

[0071] Specifically, the threaded holes 31 provided in the support plate 27 and the I-shaped turntable 29 correspond one by one, and bolts 32 are threadedly connected in the threaded holes 31. By rotating the bolts 32, the support plate 27 is brought into abutment with or separated from the I-shaped turntable 29, so that the turntable mechanism 6 can be rotationally locked and unlocked, enabling one person to complete the water quality sampling and reducing the labor cost.

[0072] Embodiment Six:

[0073] See Figure 6 , based on the above embodiments, further and optionally, a bracket 3 is provided below the mounting plate 4, and the bracket 3 includes:

[0074] A bottom plate 10 located below the mounting plate 4, a plurality of mounting holes 11 are provided in the bottom plate 10, a plurality of support rods 12 are fixed between the bottom plate 10 and the mounting plate 4, and two diagonal rods 13 are cross-arranged between adjacent support rods 12.

[0075] Specifically, the support rods 12 are used to support the mounting plate 4 and the components on the mounting plate 4. Two diagonal rods 13 are cross-arranged between adjacent support rods 12, which can enhance the stability of the support. A plurality of mounting holes 11 are provided in the bottom plate 10, which facilitates installing the device on a ship hull or a certain heavy object through the mounting holes 11. Of course, in practice, the bracket 3 can also be of other structures.

[0076] Further and optionally, the visual monitoring terminal is used to receive, view and store the data information sent by the data collector 2.

[0077] Specifically, the data collector 2 receives the detection data of the distance sensor 25 and the displacement sensor 26 through a wireless communication method, and then sends the detection data to the visual monitoring terminal through a 5G module or a WIFI module. The visual monitoring terminal can receive the data information sent by the data collector 2 and store the data for convenient retrieval and viewing by the operator.

[0078] In summary, compared with the prior art, the advantages of the present utility model are:

[0079] 1. In this application, the water sample collection device 1 is installed at the edge of the ship. By adjusting the length of the sampling tube 7 lowered and the length of the horizontal telescopic frame 5 extended according to requirements, water samples can be collected in layers at different distances from the hull and different water depths, so as to accurately monitor the water samples at different water depth levels at different distances from the ship. The purpose of setting the weight disk 8 is to facilitate the vertical lowering of the sampling tube 7 and further ensure the precise control of the sampling point position;

[0080] 2. In this application, a distance sensor 25 and a displacement sensor 26 are set on the weight disk 8, which is convenient for operators to accurately know the depth of water quality sampling according to the information detected by the sensors, and can also be used to judge the depth error range value compared with the sampling at the scale 33, so as to facilitate operators to select appropriate situations for water sample collection;

[0081] 3. The horizontal telescopic frame 5 in this application is convenient for telescoping through the horizontal telescopic mechanism 18, driving the first limit slide plate 17 on the second limit groove 15 to move in the second limit groove 15 and the first chute 16. When the second limit groove 15 slides out of the first limit groove 14, it is convenient to drive the sampling tube 7 forward. On the contrary, it can prevent the sampling tube 7 from being completely retracted on the turntable mechanism 6, and the sampling tube 7 needs to be laid out again during the second sampling, which will affect the sampling efficiency;

[0082] 4. In this application, a second chute 20 is set on the first limit groove 14, and a second limit slide plate 21 is slidably connected in the second chute 20. The purpose is to strengthen the cooperation and fixation between the second limit groove 15 and the first limit groove 14, so as to facilitate the second limit groove 15 to bear force and avoid easy fracture of the connection point, etc.;

[0083] 5. The limit structure 19 in this application is beneficial to limit the sampling tube 7, and at the same time is beneficial to reducing the friction force during the lowering and recovery of the sampling tube 7;

[0084] 6. In this application, by rotating the bolt 32, the support plate 27 is made to abut against or separate from the I-shaped turntable 29, so that the turntable mechanism 6 can be rotationally locked and unlocked, enabling one person to complete the water quality sampling and reducing the labor cost;

[0085] 7. The data collector 2 in this application receives the detection data of the distance sensor 25 and the displacement sensor 26 through wireless communication, and then sends the detection data to the visual monitoring terminal through the 5G module or WIFI module. The visual monitoring terminal can receive the data information sent by the data collector 2 and store the data to facilitate the operators to retrieve and view.

[0086] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical object dimensions can be arbitrarily changed.
