[0001] This utility model relates to the technical field of water quality testing, and in particular to the technical field of online water quality testing instruments. Background Technology

[0002] The quality of drinking water is closely related to human health. With the development of society and the economy, scientific progress and the improvement of people's living standards, people's requirements for water quality are constantly increasing, and water quality standards are also constantly developing and improving. Water quality testing devices are a common type of device, which plays an important role in environmental protection and water quality testing, and helps people to keep track of water quality in real time.

[0003] For example, Chinese utility model patent with publication number CN221367378U proposes a water quality testing float; the water quality testing float includes: a float box, an upper seat, and a testing seat. The upper seat is located at the upper end of the float box, and the testing seat is installed at the upper end of the upper seat. The testing seat, the upper seat, and the float box work together to form the frame of the entire water quality testing float; a stabilizing mechanism is installed at the lower end of the float box; an adjusting mechanism is distributed and installed around the outer perimeter of the float box; and a testing mechanism is installed at the upper end of the testing seat.

[0004] However, due to the different buoyancy of different pollutants, the water quality at different depths in the water source may be different. The problem with existing water quality testing institutions, including the patents mentioned above, is that they can only test the water quality at a fixed depth and cannot automatically adjust the sampling depth to sample and test the water quality at different depths, resulting in insufficient testing. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the existing technology and to propose an online water quality testing instrument that can sample and test water at different depths for more comprehensive testing.

[0006] To achieve the above objectives, this utility model proposes an online water quality testing instrument, comprising a main testing unit and several floats arranged around the circumference of the main testing unit. The floats are fixedly connected to the main testing unit via several brackets. The main testing unit contains a testing mechanism and a control main board connected to the testing mechanism. The control main board is equipped with a communication module. The main testing unit also contains a sampling module for cooperating with the testing mechanism. The sampling module includes a sampling pump and a sampling tube connected to the input end of the sampling pump. The output end of the sampling pump cooperates with the testing mechanism. The input end of the sampling tube extends from the lower side of the main testing unit and is equipped with a counterweight. The main testing unit also contains a winch with a rope attached. The end of the rope is fixedly connected to the input end of the sampling tube. The control main board is connected to the winch.

[0007] Preferably, the detection host is also equipped with a roller-type meter counter for cooperating with the rope, the rope passes through the roller of the roller-type meter counter, and the roller-type meter counter is connected to the control motherboard for data communication.

[0008] Preferably, the detection host or the float has several rings on its side, and anchor rods are inserted into the rings, with the anchor rods axially slidably connected to the rings.

[0009] Preferably, the detection host or the floating block is provided with a plurality of photovoltaic panels and a battery electrically connected to the photovoltaic panels, and the battery is electrically connected to the control main board.

[0010] Preferably, the detection mechanism includes a detector, a turntable, and a lifting driver. The detector is vertically positioned inside the detection host and has a detection probe. The turntable is located below the detector and has several sampling bottles corresponding to the positions of the detection probes. A rotation driver is located below the turntable to drive its rotation, and a lifting driver is located below the rotation driver to drive the turntable to move up and down. The output end of the sampling pump has a rigid sample outlet tube, which corresponds to the position of the sampling bottle.

[0011] Preferably, the distance between the rigid sample outlet tube and the detection probe is smaller than the distance between two adjacent sampling bottles.

[0012] Preferably, the bottom surface of the detection host is at the same horizontal level as the bottom surface of the float, so that when the detection host is placed on the water surface, there is a gap between the bottom surface of the detection host and the water surface.

[0013] The beneficial effects of this utility model of an online water quality testing instrument are as follows: This utility model, by setting up a winch device in conjunction with the sampling tube at the input end of the sampling pump, can drive the input end of the sampling tube to rise and fall by winding and unwinding the rope of the winch, thereby controlling the sampling depth of the sampling tube. It can detect water quality at different depths, making the detection more comprehensive and the control more convenient. It can be remotely operated, and setting a counterweight at the end of the sampling tube can keep the input port of the sampling tube in a downward state at all times.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0022] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0023] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0025] See Figures 1-4This utility model discloses an online water quality testing instrument, comprising a testing host 1 and four floats 2 arranged around the periphery of the testing host 1. The floats 2 are fixedly connected to the testing host 1 via brackets 3. The floats 2 are used to float on the water surface and provide support. The testing host 1 contains a testing mechanism and a control main board connected to the testing mechanism. The control main board is equipped with a communication module. The testing host 1 also contains a sampling module for cooperating with the testing mechanism. The sampling module includes a sampling pump 4 and a sampling tube 5 connected to the input end of the sampling pump 4. The output end of the sampling pump 4 cooperates with the testing mechanism. The input end of the sampling tube 5 extends from the lower side of the testing host 1 and is equipped with a counterweight 51. The testing host 1 also contains a winch 6, which is equipped with a rope 61. The end of the rope 61 is fixedly connected to the input end of the sampling tube 5. The control main board is connected to the winch 6. In this embodiment, a winch is set up to work with the sampling tube at the input end of the sampling pump. The input end of the sampling tube 5 can be raised and lowered by the winch 6 winding and unwinding the rope 61, thereby controlling the sampling depth of the sampling tube 5. This allows for the detection of water quality at different depths, making the detection more comprehensive and the control more convenient. It can also be remotely operated. Setting a counterweight 51 at the end of the sampling tube 5 can keep the input port of the sampling tube 5 in a downward state.

[0026] See Figure 3 The detection host 1 is also equipped with a roller-type meter counter 7 for cooperating with the cable 61. The cable 61 passes through the roller of the roller-type meter counter 7, and the roller-type meter counter 7 is connected to the control main board for data communication. The roller-type meter counter 7 can be used to calculate the extension length of the cable 61, thereby calculating the sampling depth, resulting in more accurate data.

[0027] See Figure 1 The detection host 1 has several rings 8 on its side, and anchor rods 9 are inserted into the rings 8. The anchor rods 9 are axially slidably connected to the rings 8. After passing through the rings 8, the anchor rods 9 are inserted into the bottom of the water, which can position the detection host 1 in a fixed position in the water. When the water level changes, the rings 8 can rise and fall along the anchor rods 9 to automatically adjust.

[0028] See Figure 1 The detection host 1 is equipped with several photovoltaic panels 10 and a battery electrically connected to the photovoltaic panels 10. The battery is electrically connected to the control main board. Photovoltaic power supply saves energy.

[0029] See Figure 2The bottom surface of the detection host 1 is level with the bottom surface of the float 2, so that when it is placed on the water surface, there is a gap between the bottom surface of the detection host 1 and the water surface. This arrangement allows the bottom of the detection host 1 to be off the water surface, keeping the detection host 1 dry and preventing water from entering the detection host 1 and affecting the detection or causing damage to the equipment. Example 2

[0030] See Figure 3 Based on Embodiment 1, the detection mechanism includes a detector 11, a turntable 12, and a lifting driver 13. The detector 11 is vertically disposed inside the detection host 1, and a detection probe 111 is provided on the detector 11. The turntable 12 is disposed below the detector 11, and a plurality of sampling bottles 121 corresponding to the positions of the detection probes 111 are provided on the turntable 12. A rotation driver 122 for driving the turntable 12 to rotate is provided below the turntable 12, and a lifting driver 13 for driving the turntable 12 to move up and down is provided below the rotation driver 122. A rigid sample outlet tube 41 is provided at the output end of the sampling pump 4, and the rigid sample outlet tube 41 corresponds to the position of the sampling bottle 121. In this embodiment, multiple sampling bottles 121 are set on the turntable 12 for collecting and storing samples. During sampling, the rotary driver 122 drives the turntable 12 to rotate so that a sampling bottle 121 moves to the lower end of the sampling pump 4. The lifting driver 13 drives the turntable 12 to rise so as to close the distance between the sampling bottle 121 and the rigid sample outlet tube 41. The sampling pump 4 works to collect water samples into the sampling bottle 121. Then the sampling pump 4 is turned off, the lifting driver 13 drives the turntable 12 to fall, the rotary driver 122 rotates again to rotate the sampling bottle 121 to the lower side of the detector 11, and the lifting driver 13 drives the turntable 12 to rise so that the detection probe 111 extends into the sampling bottle 121 to contact the water sample and detect the water sample. After the detection is completed, the lifting driver 13 drives the turntable 12 to fall.

[0031] See Figure 4 The distance between the rigid sample outlet tube 41 and the detection probe 111 is smaller than the distance between two adjacent sampling bottles 121. This arrangement ensures that when the lifting driver 13 drives the turntable 12 to rise, the rigid sample outlet tube 41 and the detection probe 111 will not fall into two adjacent sampling bottles 121 simultaneously, thus preventing the detection probe 111 from being contaminated by extending into the adjacent sampling bottle 121 during the sampling process, which would affect the detection accuracy.

[0032] The working process of this utility model:

[0033] In the operation of this utility model of an online water quality testing instrument, during sampling, the rotary driver 122 drives the turntable 12 to rotate so that a sampling bottle 121 moves to the lower end of the sampling pump 4. The lifting driver 13 drives the turntable 12 to rise, so as to close the distance between the sampling bottle 121 and the rigid sample outlet tube 41. The input end of the sampling tube 5 can be raised and lowered by the winch 6 winding and releasing the rope 61, thereby controlling the sampling depth of the sampling tube 5 and enabling the testing of water quality at different depths. The sampling pump 4 works to collect water samples into the sampling bottle 121. Then the sampling pump 4 is turned off, the lifting driver 13 drives the turntable 12 to descend, the rotary driver 122 rotates again, and rotates the sampling bottle 121 to the lower side of the testing instrument 11. The lifting driver 13 drives the turntable 12 to rise so that the detection probe 111 extends into the sampling bottle 121 to contact the water sample and test the water sample. After the test is completed, the lifting driver 13 drives the turntable 12 to descend.
