[0028] See also Figure 1 , Figure 3 The embodiment of the present application provides a portable online water quality monitoring device, which may include a monitoring box 1, a cylinder placement portion 2 and a water collecting cylinder 3, wherein the cylinder placement portion 2 is arranged on one side of the monitoring box 1, and the cylinder placement portion 2 is provided with a cylinder placement cavity 201 in its length direction; the water collecting cylinder 3 is placed in the cylinder placement cavity 201 and is connected to the monitoring box 1, and a driving mechanism 301 is arranged in the water collecting cylinder 3, and the output end of the driving mechanism 301 is connected to a push block structure 3 02, the push block structure 302 has the freedom to move along the output end of the driving mechanism 301, and a plurality of water inlet mechanisms 303 and a plurality of drainage mechanisms 304 are arranged at intervals on the side wall of the water collecting cylinder 3. The plurality of water inlet mechanisms 303 correspond to the plurality of drainage mechanisms 304 one by one and are arranged relatively on the side wall of the water collecting cylinder 3. When the push block structure 302 moves to the relative water inlet mechanism 303 and drainage mechanism 304, the water inlet mechanism 303, the push block structure 302 and the drainage mechanism 304 are interconnected.

[0029] Specifically, when monitoring water quality, the portable online water quality monitoring device of the utility model first takes out the water collecting cylinder 3 from the cylinder placing cavity 201 of the cylinder placing part 2 and puts it into the water body to be monitored. Since a plurality of water inlet mechanisms 303 and a plurality of drainage mechanisms 304 are arranged at intervals on the side wall of the water collecting cylinder 3, these mechanisms are arranged relatively on the side wall of the water collecting cylinder 3. When the water collecting cylinder 3 is put into the water body to be monitored, the water enters the inside of the water collecting cylinder 3 through the water inlet mechanism 303. Subsequently, the driving mechanism 301 is started to drive the push block structure 302 to move along its output end. When the push block structure 302 moves to a position aligned with a certain water inlet mechanism 303 and a drainage mechanism 304 opposite thereto, the water inlet mechanism 303, the push block structure 302 and the drainage mechanism 304 will be interconnected to form a water flow channel. At this time, the water inside the water collecting cylinder 3 will be discharged through this channel. Since the movement of the push block structure 302 is controlled by the driving mechanism 301, the opening and closing of each water inlet mechanism 303 and the drainage mechanism 304 can be accurately controlled, thereby realizing the sampling of the water body. At the same time, since the water inlet mechanism 303 and the drainage mechanism 304 are arranged opposite to each other on the side wall of the water collection cylinder 3, it can be ensured that the water sampled each time is taken out from the same position of the water collection cylinder 3, thereby improving the accuracy of sampling.

[0030] In this embodiment, a water collecting cylinder 3 is arranged on the monitoring box 1, and the water quality of the area to be detected is collected by the water collecting cylinder 3. A driving mechanism 301 is arranged in the water collecting cylinder 3, and the driving mechanism 301 drives the push block structure 302 to move, so as to achieve the coordination with the water inlet mechanism 303 and the drainage mechanism 304 at different positions, and sample the water quality at different depths. This method not only ensures the accuracy of sampling, but also improves the efficiency of sampling. At the same time, since the water collecting cylinder 3 can be easily taken out and put in, the water quality of the area to be monitored at different depths can be easily monitored online.

[0031] See also Figure 3 The interior of the water collecting barrel 3 has a first chamber 305 and a second chamber 306 which are isolated from each other in the direction of its own height; the driving mechanism 301 may include a servo motor 3011 and a screw rod 3012, wherein the servo motor 3011 is fixed in the first chamber 305; the screw rod 3012 is connected to the output end of the servo motor 3011 through a coupling, the screw rod 3012 is located in the second chamber 306, the screw rod 3012 is rotatably matched with the second chamber 306, and the screw rod 3012 is threadedly matched with the push block structure 302.

[0032] Specifically, when the servo motor 3011 is started, its output end will drive the screw rod 3012 to rotate. Since the screw rod 3012 and the push block structure 302 are threadedly matched, the push block structure 302 will move along the axial direction of the screw rod 3012 under the rotation of the screw rod 3012. This movement method is both accurate and stable, and can ensure that the push block structure 302 can accurately move to the specified position each time sampling. At the same time, since the screw rod 3012 is rotationally matched with the second chamber 306, the rotation of the screw rod 3012 will not be disturbed by the movement of the push block structure 302, thereby ensuring the normal operation of the drive mechanism 301.

[0033] In this embodiment, the interior of the water collecting cylinder 3 is divided into a first chamber 305 and a second chamber 306, and this design helps to achieve a compact layout of the driving mechanism 301 and the push block structure 302. The first chamber 305 is used to accommodate the servo motor 3011, etc., while the second chamber 306 is used to install mechanical components such as the screw rod 3012 and the push block structure 302. This partition design not only optimizes the spatial layout, but also improves the reliability and stability of the equipment.

[0034] See also Figure 4 The push block structure 302 may include a sleeve 3021 and a push block body 3022, wherein a thread is provided on the inner wall of the sleeve 3021, and the sleeve 3021 is threadedly matched with the screw rod 3012; the push block body 3022 is fixed to the outer periphery of the sleeve 3021, and an inlet pipe, an outlet pipe and a transfer pipe are provided on the push block body 3022; the inlet pipe includes a first pipe 3023 and a second pipe 3024, the outlet pipe includes a fourth pipe 3026, and the transfer pipe includes a third pipe 3025, wherein the first pipe 3023 and the second pipe 3024 are connected to the water inlet mechanism 303, the third pipe 3025 connects the first pipe 3023, the second pipe 3024 and the fourth pipe 3026, and the fourth pipe 3026 is connected to the drainage mechanism 304.

[0035] Specifically, the design of the push block structure 302 is ingenious and efficient. The inner wall of the sleeve 3021 is provided with a thread, so that it is possible to cooperate with the thread of the screw rod 3012, thereby ensuring that the push block structure 302 can move along its axial direction under the drive of the screw rod 3012. The push block body 3022 is fixed to the outer periphery of the sleeve 3021, which can ensure that the relative position between the push block body 3022 and the sleeve 3021 is stable. The push block body 3022 is provided with a first pipe 3023, a second pipe 3024, a third pipe 3025 and a fourth pipe 3026, which are connected to each other and together constitute the water flow channel of the push block structure 302. The first pipe 3023 and the second pipe 3024 are connected with the water inlet mechanism 303, so that when the push block structure 302 moves to a position aligned with a certain water inlet mechanism 303, water can enter the push block structure 302 through the first pipe 3023 and the second pipe 3024. The third pipe 3025 connects the first pipe 3023, the second pipe 3024 and the fourth pipe 3026, so that when the push block structure 302 moves to a position aligned with a drainage mechanism 304, the water can be discharged through the fourth pipe 3026. This design not only realizes the timed sampling of the water body, but also ensures the accuracy of the sampling.

[0036] See also Figure 4 , Figure 5 The water inlet mechanism 303 may include a matching hole 3031, a first water inlet hole 3032, a second water inlet hole 3033, a slider 3034, a matching plate 3035, a plurality of first springs 3036 and a blocking plate 3037, wherein the matching hole 3031 is provided on the side wall of the water collecting cylinder 3; the first water inlet hole 3032 is provided on the side wall of the water collecting cylinder 3; the second water inlet hole 3033 is provided on the side wall of the water collecting cylinder 3, and the matching hole 3031 is located between the first water inlet hole 3032 and the second water inlet hole 3033. The first water inlet hole 3032 and the second water inlet hole 3033 are connected with the water inlet pipe on the push block structure 302; the slider 3034 is movably set in the matching hole 3031; the matching plate 3035 is set at the end of the slider 3034; a plurality of first springs 3036 are set between the matching plate 3035 and the outer wall of the water collecting tube 3; the blocking plate 3037 is fixed on the slider 3034, and the blocking plate 3037 can be adapted to the first water inlet hole 3032 and the second water inlet hole 3033.

[0037] Specifically, the matching hole 3031 is provided on the side wall of the water collecting tube 3, which provides space for the movement of the slider 3034. The first water inlet hole 3032 and the second water inlet hole 3033 are respectively provided on the side wall of the water collecting tube 3, which are connected with the push block structure 302, so that the water body can enter the inside of the push block structure 302. In particular, the matching hole 3031 is located between the first water inlet hole 3032 and the second water inlet hole 3033. This layout enables the slider 3034 to simultaneously control the switch state of the first water inlet hole 3032 and the second water inlet hole 3033 when moving. The matching plate 3035 is arranged at the end of the slider 3034, which increases the structural strength of the slider 3034 and is also convenient for matching with an external mechanism. A plurality of first springs 3036 are arranged between the matching plate 3035 and the outer wall of the water collecting tube 3, and these springs provide a reset force for the slider 3034, so that the slider 3034 can automatically return to the initial position when not subjected to external force. The blocking plate 3037 is fixed on the slider 3034, and its size and shape are adapted to the first water inlet hole 3032 and the second water inlet hole 3033. When the slider 3034 moves to a certain position, the blocking plate 3037 can block the first water inlet hole 3032 or the second water inlet hole 3033, thereby controlling the flow direction of the water body. This design is simple and practical, and can realize sampling of water quality at different depths.

[0038] In this embodiment, the ingenious design of the water inlet mechanism 303 enables the water collection tube 3 to sample water quality at different depths. The movement of the slider 3034 in the matching hole 3031, in conjunction with the shielding effect of the blocking plate 3037, can accurately control the switch state of the first water inlet hole 3032 and the second water inlet hole 3033, thereby determining from which water inlet hole the water enters the push block structure 302. This design is not only flexible, but also can ensure the accuracy of sampling.

[0039] See also Figure 4 , Figure 5 The drainage mechanism 304 may include a sliding groove 3041, a sliding block 3042, a second spring 3043 and a drainage pipe 3044, wherein the sliding groove 3041 is opened on the inner wall of the water collecting barrel 3; the sliding block 3042 is arranged in the sliding groove 3041, and the sliding block 3042 has the freedom of movement along the radial direction of the water collecting barrel 3 in the sliding groove 3041; the second spring 3043 is arranged between the sliding groove 3041 and the sliding block 3042; the drainage pipe 3044 is arranged on the sliding block 3042, and the drainage pipe 3044 is connected to the water outlet pipe of the push block structure 302.

[0040] Specifically, the opening of the sliding groove 3041 provides necessary space for the movement of the sliding block 3042, and since the sliding groove 3041 is opened on the inner wall of the water collecting tube 3, the movement of the sliding block 3042 is carried out along the radial direction of the water collecting tube 3. This layout not only saves space, but also makes the structure of the drainage mechanism 304 more compact. The freedom of movement of the sliding block 3042 in the sliding groove 3041 is one of its core functions, which can open or close the drain pipe 3044 when needed, thereby controlling the discharge of the water body. The second spring 3043 is arranged between the sliding groove 3041 and the sliding block 3042, providing a reset force for the sliding block 3042, so that the sliding block 3042 can automatically return to the initial position when there is no external force. The drain pipe 3044 is arranged on the sliding block 3042 and is connected to the push block structure 302, so that when the sliding block 3042 moves to a certain position, the water body can be discharged through the drain pipe 3044. This design is simple and practical, and can achieve accurate control of the water body.

[0041] In this embodiment, the design of the drainage mechanism 304 enables the water collection tube 3 to achieve accurate control of the water body. Through the movement of the sliding block 3042 in the sliding groove 3041 and the reset action of the second spring 3043, the switch state of the drainage pipe 3044 can be accurately controlled. This design is not only flexible, but also can ensure the accurate discharge of the water body.

[0042] See also Figure 3 A first water pipe 4 is provided on the inner wall of the second chamber 306 , and a water pump 5 is provided in the first chamber 305 , and the water pump 5 is connected to the first water pipe 4 .

[0043] Specifically, the opening of the first water pipe 4 establishes a connection between the second chamber 306 and the water pump 5. The water pump 5 is placed in the first chamber 305, which is convenient for the maintenance and replacement of the water pump 5. The water pump 5 is connected to the second chamber 306 through the first water pipe 4, so that when the water pump 5 is working, it can extract the water in the second chamber 306 and then transport it to the detection device.

[0044] In this embodiment, the provision of the water pump 5 makes the water collection tube 3 have stronger functionality. Through the operation of the water pump 5, the water in the second chamber 306 can be transported to the detection device, so as to detect the water quality. This design not only improves the practicality of the water collection tube 3, but also makes the process of water quality sampling and processing more efficient and convenient.

[0045] See also Figure 2The monitoring box 1 may include a box body 101, a plurality of universal wheels 102, a pull rod 103 and a water quality detection mechanism 104, wherein the box body 101 has a first side surface and a second side surface that are arranged opposite to each other, and the first side surface faces the ground; the plurality of universal wheels 102 are fixed to the side of the first side surface that is away from the second side surface; the pull rod 103 is arranged on one side of the box body 101; the water quality detection mechanism 104 is arranged inside the box body 101, and the water quality detection mechanism 104 is connected to the water collecting cylinder 3 through a pipeline.

[0046] Specifically, the box body 101 serves as the main structure of the entire monitoring box 1, providing space for installation and protection of internal equipment. A plurality of universal wheels 102 are fixed on the first side, which allows the monitoring box 1 to be easily moved and transported. The pull rod 103 is arranged on one side of the box body 101, providing the user with a convenient dragging method, making it more labor-saving when moving the monitoring box 1. The water quality detection mechanism 104 is the core part of the monitoring box 1, responsible for detecting and analyzing the water quality sampled from the water collection tube 3. The water quality detection mechanism 104 is connected to the water collection tube 3 through a pipeline, and can receive the water sample extracted from the water collection tube 3, and then use the internal detection equipment to perform water quality detection.

[0047] In this embodiment, the design of the monitoring box 1 fully considers the needs of practical applications. Through reasonable structural layout and equipment configuration, the entire monitoring box 1 has both powerful functionality and convenient operability and mobility.

[0048] See also Figure 2 The water quality detection mechanism 104 may include a turbidity detector 1041, a water quality analysis mechanism 1042 and a water outlet pipe 1043, wherein the turbidity detector 1041 is connected to the water collecting cylinder 3 through a pipeline; the water quality analysis mechanism 1042 is connected to the turbidity detector 1041 through a pipeline; one end of the water outlet pipe 1043 is connected to the water quality analysis mechanism 1042, and the other end extends out of the box 101.

[0049] Specifically, the turbidity detector 1041, as an important component of the water quality detection mechanism 104, is directly connected to the water collection tube 3 through a pipeline. In this way, the water sample extracted from the water collection tube 3 can directly flow into the turbidity detector 1041 for detection. The turbidity detector 1041 can quickly and accurately measure the turbidity of the water sample and provide basic data for water quality analysis. The water quality analysis mechanism 1042 is the core part of the water quality detection mechanism 104. It is connected to the turbidity detector 1041 through a pipeline and can receive the water sample that has been tested for turbidity. The water quality analysis mechanism 1042 can perform comprehensive chemical and biological analysis on the water sample, thereby obtaining more detailed and comprehensive water quality information.

[0050] In this embodiment, the design of the water quality detection mechanism 104 fully considers the comprehensiveness and accuracy of water quality detection. Through the coordinated use of the turbidity detector 1041 and the water quality analysis mechanism 1042, comprehensive detection and analysis of water quality can be achieved.
