Specific embodiments

[0026] The following further elaborates on the content of the present application in conjunction with specific embodiments:

[0027] Refer to Figures 1 to 5 , an embodiment of the present application provides a water environment monitoring device, which may include a device unit, a connecting piece 2, and an adapter structure part 3. The device unit includes a device main body 1 and auxiliary devices. Both the device main body 1 and the auxiliary devices are used for water quality monitoring or hydrological monitoring or water sample collection. The auxiliary devices at least include an electromagnetic flowmeter 5. The auxiliary devices are detachable, and the number of the auxiliary devices is one or more. The device main body 1 and the auxiliary devices are connected by a cable 9. The connecting piece 2 has a through hole 202 for the device main body 1 and the cable 9 to pass through respectively. At least part of the through hole 202 is connected by a docking seam 201. As Figure 5 shown, the two ends of the connecting piece 2 extending in the length direction are first mounting parts 203, and the length direction of the docking seam 201 coincides with the extending direction of the first mounting part 203. As Figure 4 shown, the docking seam 201 can be communicated with the ends of the first mounting part 203 at both ends, and the connecting piece 2 is divided into two detachable split plates; the adjacent parts of the two plates are opposite to form the docking seam 201. As Figure 3 shown, the docking seam 201 can also be communicated with only one end of the first mounting part 203. In this way, the two plates are integrated, and the docking seam 201 formed by the adjacent parts of the two plates opposite to each other constitutes an integrated elastic clamp of the connecting piece 2. When needed, the width of the docking seam 201 is enlarged to facilitate the disassembly of the connecting piece 2 from other components. As Figure 4 shown, the docking seam 201 can symmetrically divide the connecting piece 2 in a mirror image. The docking seam 201 itself extends in a straight line, and the centroid of at least part of the through hole 202 on the connecting piece 2 coincides with the docking seam 201.

[0028] In some other embodiments, the adapter structure 3 is disposed between the device main body 1 and the auxiliary device. The adapter structure 3 has limiting concave curved surfaces 301 respectively used for forming surface contact with the side facade of the device main body 1 and the side facade of the auxiliary device. The adapter structure 3 and the clamping plate of the connecting member 2 are fixedly assembled.

[0029] The beneficial effects of adopting the above technical solutions are as follows: First, since the adapter structure 3 is located between the device main body 1 and the auxiliary device, it fills the original gap between the device main body 1 and the auxiliary device, enabling these originally independent device units to form a complete whole, with stable connection, and is suitable for the field of water flow monitoring. Second, due to the limiting concave curved surface 301 of the adapter structure 3, there is sufficient contact area between the adapter structure 3 and the device main body 1 and the auxiliary device, which can stably limit the cylindrical device units. At the same time, the adapter structure 3 also fixes the split connecting members 2 together, enabling the originally separated connecting members 2 to be mutually fixed by means of the adapter structure 3, thus having the ability to long-term assemble and clamp the device units.

[0030] In some other embodiments, the device main body 1 and the auxiliary device are mainly distinguished by whether they can be disassembled, that is, in the water environment monitoring device, the one that never needs to be replaced is the device main body 1, and the one that can be selected and replaced is the auxiliary device. The volume of a single device main body 1 can be larger than that of a single auxiliary device. The outer wall shapes of the device main body 1 and the auxiliary device can both be rotational body shapes mainly in the form of a cylinder. And the device main body 1 itself can be an independently operable water quality monitoring device. The water environment monitoring device of the present application can be applied to surface water or underground pipe network systems.

[0031] As Figure 3 shown in the top view, the contour shape of the connecting member 2 itself is an axisymmetric figure.

[0032] The beneficial effects of adopting the above technical solutions are as follows: The specially designed connecting member 2 and adapter structure 3 are beneficial to integrating water quality monitoring device units with different functions. At the same time, both the connecting member 2 and the adapter structure 3 can improve the stability of assembling these device units together. The connecting member 2 plays a role of surrounding and limiting, restricting the relative positions between the device units, and the adapter structure 3 prevents the device units from swinging and loosening.

[0033] Figure 4 The explosion diagram of Figure 4 shows that the connecting member 2 and the bottom support plate 7 are separated vertically by a certain distance. In some other embodiments of the present application, as Figure 5As shown, the tangent direction at the junction of the flow guiding surface 303 and the circumferential surface (the tangent direction at the junction of the flow guiding surface 303 and the circumferential surface is the tangent direction of the circumferential surface at the junction of the flow guiding surface 303 and the circumferential surface) forms a transition angle α, and the transition angle α is a flat angle with an included angle of 180° or an obtuse angle, where, Figure 5 The dotted line is used as the extension reference line of the circumferential surface tangent direction and the flow guiding surface 303.

[0034] The radius of curvature of the concave surface 302 for limiting can be equal to the radius of curvature of the side elevation of the adjacent equipment unit.

[0035] The beneficial effects of adopting the above technical solution are as follows: The concave surface 302 for limiting ensures that there is sufficient contact area between the adapter structure member 3 and the equipment main body 1 and the auxiliary equipment, so as to ensure that the equipment main body 1 and the auxiliary equipment are stably limited. The function of the flow guiding surface 303 is to reduce the volume of the adapter structure member 3 on the premise of ensuring the shape and size of the concave surface 302 for limiting, making the whole water environment monitoring equipment more structurally compact, and also making the side elevation of the equipment main body 1, the auxiliary equipment and the adapter structure member 3 as a whole smooth, suitable for being immersed in flowing liquid, and the flow guiding surface 303 generates less resistance in the flowing liquid.

[0036] In some other embodiments of the present application, such as Figure 1 As shown, the top surface of the adapter structure member 3 can be fixedly assembled with the bottom surface of the connecting member 2. The water environment monitoring equipment further includes a bottom support plate 7, and the bottom support plate 7 can be fixedly assembled with the bottom surface of the adapter structure member 3. The bottom support plate 7 performs circumferential limiting or supporting limiting on the auxiliary equipment.

[0037] The beneficial effects of adopting the above technical solution are as follows: In theory, the adapter structure member 3 is sufficient to fix the connecting member 2, the equipment main body 1 and the auxiliary equipment together, but the additional bottom support plate 7 can further improve the stability after assembly, especially the bottom of the auxiliary equipment far from the connecting member 2. This can ensure that the equipment main body 1 and the auxiliary equipment always maintain a parallel arrangement to each other, improving the accuracy of measurement data.

[0038] In some other embodiments, such as Figure 4 As shown, the connecting member 2, the adapter structure member 3 and the bottom support plate 7 are all provided with docking fixing holes 10, and fasteners for fixedly assembling the connecting member 2, the adapter structure member 3 and the bottom support plate 7 with each other are arranged in the fixing holes 10.

[0039] The fasteners can be standard parts such as screws and bolts with unified specifications.

[0040] The beneficial effects of adopting the above technical solution are as follows: It details the disassembly and assembly methods between the connecting member 2, the adapter structure member 3, the bottom support plate 7 and the equipment main body 1 and the auxiliary equipment.

[0041] In other embodiments, the surface of the device body 1 is provided with filter holes 101 for liquid to pass through, and the bottom support plate 7 is located below the device body 1. Figure 2 , Figure 4 As shown, the bottom surface of the auxiliary device is lower than the bottom surface of the device body 1, the bottom support plate 7 has a hollow hole 703 that exposes the filter hole 101 on the bottom surface of the device body 1, and the bottom support plate 7 has a circular hoop 701 and / or a C-shaped hoop 702 that surrounds and limits the auxiliary device. Such a design does not affect the measurement results of the device body 1 and the auxiliary device.

[0042] like Figure 6 As shown, the protective cover of the device body 1 has filter holes 101 on the circumferential surface as the side surface and the bottom surface.

[0043] The beneficial effects of adopting the above technical solution are: first, the hollow hole 703 reduces the negative effect of the bottom support plate 7 on the equipment body 1, and reduces the blocking of the filter hole 101 by the bottom support plate 7. Second, the circular hoop 701 and the C-shaped hoop 702 are named according to their respective shapes. Because the C-shaped hoop 702 is in a non-closed loop state, it can have a certain radial elastic expansion margin compared with the circular hoop 701, which can be applied to some special situations and can play a clamping effect on the auxiliary equipment in contact.

[0044] In other embodiments, Figure 1 As shown, in addition to the electromagnetic flowmeter 5, the auxiliary equipment may also include one or more of a liquid level measuring device 4, an ammonia nitrogen sensor, and a sampler 6. The axes of the equipment body 1, the liquid level measuring device 4, the electromagnetic flowmeter 5, and the sampler 6 are parallel to each other; Figure 4 As shown, the transition structure 3 also includes a position-limiting step surface 302 in contact with the outer wall of the sampler 6 , and the position-limiting step surface 302 is perpendicular to the axis of the sampler 6 .

[0045] like Figure 1 As shown, the liquid level measuring device 4 and the electromagnetic flowmeter 5 are located on the same side of the equipment body 1 , and the sampler 6 is located on the other side of the equipment body 1 .

[0046] The beneficial effect of adopting the above technical solution is that the specific functions of each auxiliary device are refined. The electromagnetic flowmeter 5 can measure the flow rate of the liquid, and the sampler 6 can sample the water body. The step surface 302 for limiting further refines the shape of the adapter structure 3, further increases the contact area, and can assist in limiting the displacement loosening of the sampler 6 along the axial direction, that is, the connector 2 and the bottom support plate 7 can limit the sampler 6 in two directions in the axial direction.

[0047] In other embodiments, Figure 1As shown, a sampling tank 12 is also detachably assembled at the top of the sampler 6, and the through hole 202 of the connecting member 2 also allows the cable 9 and the sampling tank 12 to pass through.

[0048] The beneficial effects of adopting the above technical solution are as follows: The cable 9 enables the transmission of electrical signals and data signals between the main device 1 and the auxiliary device, improving the degree of integration. The sampling tank 12 facilitates the extraction of samples via the sampler 6, and the sampling tank 12 is easy to disassemble and assemble.

[0049] In some other embodiments, such as Figure 1 As shown, a hoop 11 is also fixed on the outer wall of the main device 1. The hoop 11 is located above the connecting member 2, and the cable 9 is located outside the hoop 11. The hoop 11 can be used to install devices such as floats.

[0050] Such as Figure 2 As shown, the thickness of the connecting member 2 is greater than the thickness of the bottom support plate 7.

[0051] The beneficial effects of adopting the above technical solution are as follows: The hoop 11 further protects the upper half of the main device 1 itself, and at the same time, the hoop 11 also provides an additional fixing surface, facilitating the fixation of the entire water environment monitoring device to a certain external location. In addition, since the connecting member 2 is in direct contact with many components, its thickness is relatively large to ensure its structural strength.

[0052] In some other embodiments of the present application, one end of the cable 9 is connected to the main device 1 through a quick connector 8.

[0053] Such as Figure 1 As shown, the quick connector 8 is located at the top of the main device 1. The cable extends from the top of the main device 1 and extends downward from both sides of the main device 1, and then is connected to the auxiliary device.

[0054] The beneficial effects of adopting the above technical solution are as follows: The quick connector 8 is a fast and convenient plug-and-play connection method in the field of connection. When it is necessary to replace the auxiliary device again, the disassembly and replacement efficiency can be improved.

[0055] Figures 1 to 3 Belong to the same embodiment, while Figures 4 to 6 Belong to another embodiment. Figures 1 to 3 In the embodiment of Figures 4 to 6 there are a liquid level measuring device 4, an electromagnetic flowmeter 5, and a sampler 6, while Figures 1 to 3 in the embodiment of Figures 4 to 6 there are only an electromagnetic flowmeter 5 and a sampler 6. Therefore,

[0056] In some other embodiments, the device main body 1 and the auxiliary device may also be a combination of an electromagnetic flowmeter 5 and the device main body 1 plus an ammonia nitrogen monitoring device, which can be combined according to actual needs.

[0057] The device main body 1 may be an existing water quality monitoring device. By setting a connection structure on the device main body 1, the electromagnetic flowmeter 5 can be installed to measure the flow rate of the liquid. The electromagnetic flowmeter 5 may include an excitation coil, induction electrodes, and a grounding electrode. The principle of the electromagnetic flowmeter 5 for measuring the flow rate may be based on Faraday's law of electromagnetic induction. When a conductive fluid such as water or an acid, alkali, or salt solution passes through an externally applied magnetic field, an electromotive force will be induced in the conductor, and the magnitude of this electromotive force is proportional to the flow rate of the fluid. The corresponding formula is as follows:

[0058] E = BLV

[0059] Where: E is the induced electromotive force, B is the magnetic induction intensity of the externally applied magnetic field, L is the distance between the two electrodes of the electromagnetic flowmeter 5 in the direction perpendicular to the flow rate (i.e., the direction perpendicular to the water flow direction / fluid direction), and V is the liquid flow rate.

[0060] From the above formula analysis, it is necessary to know the magnetic induction intensity B of the externally applied magnetic field and the distance L between the two electrodes of the electromagnetic flowmeter 5 in the direction perpendicular to the flow rate in order to calculate the liquid flow rate V based on the measured induced electromotive force E.

[0061] In addition, the magnetic induction intensity B of the externally applied magnetic field is controlled by the excitation coil current. The distance L between the two electrodes of the electromagnetic flowmeter 5 in the direction perpendicular to the flow rate not only depends on the electrode distance but also is related to the angle between the flow rate direction (water flow direction / flow direction). Therefore, when installing the electromagnetic flowmeter 5, it is preferably to make the electrode connection line form a 90° angle with the flow rate.

[0062] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable those skilled in the art to understand the content of the present application and implement it. It should not be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
