DETAILED DESCRIPTION

[0040] The specific embodiments of the present application are described in detail below. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0041] In the present application, the orientation words such as "up, down" used without the opposite description generally refer to the orientation in the assembled and used state. "In, out" refers to the inside and outside relative to the outline of each component.

[0042] The present application discloses a water quality monitoring device, as shown in the accompanying drawings Figure 1 The device is used for collecting water samples at different time points at one time. The device comprises a sampling main body 5, a sampling mechanism 300, a rotating shaft 19, a vane wheel 12 and a cone 13. Specifically, the sampling main body 5 is provided with a cavity 20, and a feed slot 6 is formed in one side wall of the cavity 20. The water samples collected are stored in the cavity 20 through the feed slot 6. The sampling mechanism 300 comprises a sampling part 100, which is rotatably arranged in the cavity 20. The sampling part 100 comprises a column 101 and a plurality of partitions 103 fixed on the column 101. The partitions 103 divide the cavity 20 into a plurality of storage spaces 105 which are not connected to each other. The different storage spaces 105 are connected to the feed slot 6 in sequence through the rotation of the sampling part 100, so that the water samples are stored in the storage spaces 105 through the feed slot 6. It should be noted that the water samples stored in different storage spaces 105 are collected at different times with the rotation of the sampling part 100. Therefore, the water samples at different times can be collected at one time without repeatedly placing the device in the water area, thereby improving the work efficiency.

[0043] It should be noted that the feed trough 6 is connected to at most one of the storage spaces 105 at the separation point of the sampling mechanism 300, to avoid storing water samples collected at the same time in two adjacent storage spaces 105. In this embodiment, the thickness of the partition 103 is set to be greater than the width of the feed trough 6, so that the partition 103 ensures that the feed trough 6 is connected to at most one storage space 105 during the rotation of the main body.

[0044] Additionally, the column 101 is mounted on and rotates along with the rotating shaft 19. A reduction gearbox 11 connects the rotating shaft 19 to the impeller 12. The impeller 12 is located outside the sampling body 5, with one end of the impeller 12 rotatably mounted on the cone 13, away from the reduction gearbox 11. The placement of the impeller 12 outside the sampling body 5 allows its rotational speed to be controlled by the water flow velocity, eliminating the need for additional control energy, saving manpower and resources, and enabling automated data collection. The reduction gearbox 11 prevents excessively fast rotation of the column 101 from causing a small time difference between water samples in adjacent storage spaces 105. The cone 13 secures the entire device to the bottom of the water, ensuring stability during data collection.

[0045] In a further preferred embodiment, a pointer 1 is fixedly connected to the end of the sampling body 5 furthest from the impeller 12. The pointer 1 is used to indicate the orientation of the feed trough 6. Specifically, after the cone 13 is installed on the riverbed, the pointer 1 indicates that the orientation of the feed trough 6 is opposite to the water flow direction, thereby facilitating the collection of water samples. In this embodiment, the pointer 1 uses an arrow, with the arrow pointing in the water flow direction and the tail of the arrow facing the same direction as the feed trough 6.

[0046] In a further optimized embodiment, the indicator 1 has a connecting post 2, on which a first magnetic component 3 is fixedly connected. A second magnetic component 4 is fixedly connected to the end of the sampling body 5 furthest from the impeller 12, and the first magnetic component 3 and the second magnetic component 4 are magnetically connected. Using magnetic components to connect the indicator 1 and the sampling body 5 is convenient and quick.

[0047] In a further preferred embodiment, several sets of sampling mechanisms 300 are installed along the axial direction of the rotation axis 19. This design also enables the collection of water samples at different depths to meet more collection needs. Specifically, this utility model provides the following two embodiments. Example 1

[0048] Combined with appendix Figure 2 Appendix Figure 3In this embodiment, a plurality of sealing elements 200 are rotatably mounted on the rotating shaft 19, with sealing elements 200 provided at least between adjacent sampling mechanisms 300 to separate and seal them. Specifically, in this embodiment, the rotating shaft 19 is vertically positioned, and four types of sampling mechanisms 300 are provided and arranged vertically. The sealing elements 200 are arranged sequentially from top to bottom as a first sealing element 7, a second sealing element 8, a third sealing element 9, a fourth sealing element 10, and a fifth sealing element 14. The spaces between adjacent sealing elements 200 form a space for installing the sampling mechanism 300, that is, a total of four spaces are formed for installing the sampling mechanism 300. There are four groups of sampling mechanisms 300, that is, a total of four sampling elements 100, which are arranged sequentially from top to bottom as a first sampling body 15, a second sampling body 16, a third sampling body 17, and a fourth sampling body 18.

[0049] Several sampling mechanisms 300 are set together in the same cavity 20 and separated and sealed by a sealing element 200, which reduces the processing of the cavity 20 in the sampling body 5 and facilitates the processing and manufacturing of the sampling body 5.

[0050] In a further preferred embodiment, in conjunction with the appendix Figure 4 Along the axial direction of the rotation axis 19, the feed trough 6 is set through the sampling body 5. (Combined with attached...) Figure 5 The rotating shaft 19 is a sampling spline shaft, and the first spline hole 102 is opened in the cylinder 101 to connect with the rotating shaft 19 via a spline. (See attached diagram.) Figure 6 The seal 200 includes a sealing body 201, a protrusion 202, and a sealing bearing 203. Specifically, in conjunction with the attached... Figure 7 The protrusion 202 is fixed on the sealing body 201 and blocks the feed groove 6 along the radial direction of the rotating shaft 19, thereby separating the adjacent sampling mechanisms 300 at the feed groove 6. For the sealing bearing 203, its outer ring is fixedly installed in the sealing body 201. The sealing body 201 has a mounting hole 204 for installing the sealing bearing 203, and the inner ring of the sealing bearing 203 has a second spline hole 205 that spline-fits the rotating shaft 19, so that during the rotation of the rotating shaft 19, only the inner ring of the sealing bearing 203 rotates, without rotating the outer ring of the sealing bearing 203 or the sealing body 201. In other embodiments, a splined bushing (not shown) can be fitted inside the inner ring of the sealing bearing 203.

[0051] In a further preferred embodiment of this invention, as shown in the appendix Figure 4 As shown, the cavity 20 penetrates the sampling body 5 along the axial direction of the rotation axis 19. This arrangement facilitates the installation and removal of the seal 200 and the sampling element 100.

[0052] In a further preferred embodiment of this invention, as shown in the appendix Figure 4As shown, the feed trough 6 is set to penetrate the sampling body 5 along one side. Specifically, the feed trough 6 is set to penetrate the sampling body 5 upwards. Firstly, it is convenient to distinguish the posture of the sampling body 5. Secondly, it can also ensure the circumferential structural strength of the sampling body 5. If the feed trough 6 completely penetrates the sampling body 5 in the vertical direction, the sampling body 5 is prone to deformation. Thirdly, it is convenient to cooperate with the protrusion 202 to install the seal 200. Example 2

[0053] Combined with appendix Figure 8 The difference from Embodiment 1 is that in this embodiment, the sampling body 5 along the axial direction of the rotation axis 19 is provided with several cavities 20, and each cavity 20 has a through-hole feed groove 6 on its side wall. Specifically, each group of sampling mechanisms 300 is separated and sealed by the solid of the sampling body 5 to ensure the sealing strength.

[0054] To facilitate the installation of the sampling mechanism 300, the sampling body 5 is designed as a split unit, combined with the attached... Figure 9 Appendix Figure 10 The sampling body 5 is symmetrically divided along the vertical direction, so that the cavity 20, the feed trough 6, and the shaft hole for mounting the rotating shaft 19 are all obtained by splicing two separate structures. Additionally, a connecting part 21 is integrally formed on the separated sampling body 5, and bolt holes 22 are provided on the connecting part 21. The separate sampling body 5 can be assembled by inserting bolts. It should be noted that the connecting part 21 is located on the other side of the feed trough 6 to avoid interfering with the function of the feed trough 6 in collecting water.

[0055] In a further preferred embodiment of this utility model, in conjunction with the appendix Figure 11 Appendix Figure 12 The main body has a blocking part 104, and the length of the blocking part 104 along the circumference of the main body is greater than the length of the partition 103. Specifically, after the device is assembled and installed at the bottom of the water, the impeller 12 will come into contact with the water flow. At this time, the rotating shaft 19 will rotate to a certain extent. In order to avoid the storage space 105 from communicating with the feed trough 6 during the installation of the device at the bottom of the water, the initial state of the device after assembly is adjusted so that the blocking part 104 is facing the feed trough 6. Since the circumferential length of the blocking part 104 is greater than the length of the partition 103, the blocking part 104 has a wider coverage area for blocking the feed trough 6. The rotating shaft 19 ensures that the feed trough 6 will not communicate with the storage space 105 within a certain rotation angle range, thereby improving the reliability of the data collection function.

[0056] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0057] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0058] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
