Abstract
Description
Technical Field
[0001] This utility model relates to the field of river water quality monitoring technology, specifically a river water quality monitoring device. Background Technology
[0002] Rivers are important carriers of water resources, and their water quality directly affects the health of the ecological environment and the quality of human life. Sensor technology is a core component in river water quality monitoring. A sensor is a device that can sense environmental changes and convert signals into readable data. Commonly used sensors in water quality monitoring include conductivity sensors, dissolved oxygen sensors, pH sensors, temperature sensors, and turbidity sensors. They convert the collected data into electrical signals and transmit them to a data processing unit wirelessly or via wired means. The data is then analyzed through built-in algorithms or cloud platforms to determine the water quality.
[0003] However, when sensors are deployed in river water, directly contacting the water body and sensing specific parameters such as temperature, pH value, and dissolved oxygen concentration in real time, the environmental challenges are more severe. For example, suspended particles, sediments, and other debris in the water flow may impact the sensors, and microorganisms, algae, and other organisms can easily adhere to the sensor surface, forming biofilms that affect measurement accuracy. To address this, a river water quality monitoring device is proposed. Utility Model Content
[0004] Based on the above description, this utility model provides a river water quality monitoring device that solves the technical problems pointed out in the background art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A river water quality monitoring device, including a chassis module, wherein a sampling tube hole is provided on the chassis module, and further comprising:
[0006] The linear module is mounted on the chassis module and has a tube transfer assembly and a monitoring assembly on top;
[0007] The sampling assembly is set on the chassis module and includes two sets of upright plates. A limit rod and a lead screw device are installed on the upright plates. The nut end of the lead screw device is fixed with a lifting block that slides with the limit rod. A transverse block is provided between the lifting blocks, and a convex plate is fixed on the front. The bottom of the convex plate is connected to a sampling cylinder that is opposite to the sampling tube hole. The top is provided with a first cylinder that extends into the sampling cylinder.

[0012] Furthermore, the rack is equipped with a wireless data transmission module for transmitting water quality data collected by the sensor to an external terminal in real time.
[0013] Furthermore, a support frame is fixed between the columns of the frame plate, and fixed plates are installed on the support frame in a relatively distributed manner. A limit block is fixed on one side of the fixed plate.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] Please see Figure 1-5 This embodiment of a river water quality monitoring device includes a chassis module 1. An annular float 4 is fixed to the bottom periphery of the chassis module 1, and six connecting pipes 2 are fixed to the outer side. A sampling pipe hole 10 is fixed to the eccentric part of the bottom center. A linear module 9 is installed on the top of the chassis module 1, and a linear module 9 located below the sampling component 6. An impeller device 3 is installed at the other end of the connecting pipe 2. The wiring of the chassis module 1 is electrically connected to the impeller device 3 through the connecting pipe 2. Three sets of floats 5 are fixedly installed at the bottom of the connecting pipe 2. A pipe-moving component 7 and a monitoring component 8 located above the pipe-moving component 7 are mounted on the moving plate of the linear module 9.
[0029] In the above structure, by designing the monitoring component 8 above the chassis module 1, it is ensured that the monitoring component 8 is located below the water surface, avoiding the challenges of the complex underwater environment and preventing damage to the monitoring component 8 due to the complex underwater environment. In addition, the buoyancy of the chassis module 1 is improved by using an inflatable annular float 4 and float 5. As needed, the chassis module 1 drives the impeller device 3 to operate, allowing the chassis module 1 to move autonomously to a suitable position in the water. Then, the sampling component 6 moves above the sampling tube hole 10 and extends into the interior to complete the sampling operation in that area. After sampling is completed, it resets, and the linear module... Group 9 moves the transfer tube assembly 7 below the sampling assembly 6, aligning the sample tube with the sampling end of the sampling assembly 6. The sampling assembly 6 introduces the sample into the sample tube, while the transfer tube assembly 7 rotates to change the position of the sample tube. This, in conjunction with the sampling assembly 6, allows for sampling of the water source in the area until the sample tube rotates below the monitoring assembly 8. Under the action of the monitoring assembly 8, the sample in the sample tube is tested and recorded. After the sample tube is collected, the recovery device retrieves the sample tube. Therefore, multi-area sampling and testing can be achieved, enabling more effective monitoring of water quality.
[0030] like Figure 2-3 The sampling assembly 6 includes two sets of upright plates 61 installed on the top of the chassis module 1. A bidirectional moving device is installed between the two sets of upright plates 61. A transverse moving block 65 is fixed to the moving end of the bidirectional moving device. An L-shaped protrusion 67 is fixed to the front of the transverse moving block 65. A sampling cylinder 69 is fixed to the bottom of the protrusion 67. A first cylinder 68 that can extend into the interior of the sampling cylinder 69 is installed at the top. The piston rod of the first cylinder 68 extends into the interior of the sampling cylinder 69 and a push plate 610 with the same inner diameter as the sampling cylinder 69 is fixed thereon.
[0031] The bidirectional moving device can drive the sampling cylinder 69 to move horizontally or vertically via the transverse block 65, so that the sampling cylinder 69 can dock with the sample tube in the transfer tube assembly 7, and can also move into the sampling tube hole 10. Combined with the operation of the first cylinder 68, the push plate 610 is driven to rise, so that the water source in the area can be sucked into the sampling cylinder 69 for storage, until it docks with the sample tube. The first cylinder 68 pushes the push plate 610 to introduce the water sample into the sample tube for collection, thus completing the sampling operation.
[0032] The bidirectional moving device includes limiting guide rods 611 and lead screw devices 62 mounted on two sets of upright plates 61. A lifting block 63, which slides against the limiting guide rods 611, is fixed to the nut end of the lead screw device 62. A belt-driven transmission device 66 and two guide rods 64 are also installed between the two sets of lifting blocks 63. The transverse block 65 is slidably connected between the two guide rods 64 and fixed to the belt end of the belt-driven transmission device 66. Therefore, through the operation of the lead screw device 62 and the belt-driven transmission device 66, the lifting blocks 63 can be raised and lowered, thereby driving the sampling cylinder 69 to complete the raising and lowering. Then, the belt end of the belt-driven transmission device 66 can drive the transverse block 65 to move on the guide rods 64, thus completing the transverse movement of the sampling cylinder 69.
[0033] like Figure 4 The tube transfer assembly 7 includes a stand 71 fixed on a moving plate in the linear module 9. The top of the stand 71 is fixed with a double-layer ring plate 72 and a steel ring 75, and the bottom is equipped with a drive motor 73. There are two steel rings 75. The drive end of the drive motor 73 is fixed with a double-layer lever plate 74 located above the steel rings 75 and inside the double-layer ring plate 72. The outer side of the double-layer lever plate 74 is provided with a notch, and the steel ring 75 is located below the notch.
[0034] The linear module 9 can push the tube transfer assembly 7 forward, so that the sample tube in the notch is perpendicular to the sampling cylinder 69. Therefore, the sampling cylinder 69 introduces the water sample into the sample tube. The drive motor 73 drives the double-layer baffle 74 to rotate, thereby moving the sample tube on the steel ring 75 to adjust its position. Under the action of the double-layer ring plate 72, it can limit the sample tube from falling or shifting, thus adjusting the position of the sample tube. Together with the sampling assembly 6, water samples from multiple areas of the water can be taken out and introduced into the sample tube for collection.
[0035] like Figure 5 The monitoring component 8 includes a frame plate 81 fixed on a movable plate in the linear module 9. Two sets of second cylinders 82 are mounted on the frame plate 81. Sensors 83, opposite to the notches, are mounted on the piston rods of the second cylinders 82. A wireless data transmission module is also mounted on the top of the frame plate 81 for transmitting water quality data collected by the sensors 83 to an external terminal in real time. When the double-layer lever 74 rotates and moves the sample tube below the two sets of sensors 83, the second cylinders 82 move the sensors 83 into the sample tube to detect the water sample. Simultaneously, the data is transmitted to the terminal for analysis via the wireless data transmission module.
[0036] The frame 81 has a support frame 84 fixed between its columns. Two sets of opposing fixing plates 85 are mounted on the fixing plate 85. Limiting blocks 86 are fixed to opposite sides of the fixing plates 85, and a conical hole is formed between the two limiting blocks 86. The bottom end of the sensor 83 can pass through the conical hole. When the sensor 83 is lowered by the second cylinder 82, the sensing needle of the sensor 83 passes through the two limiting blocks 86. Simultaneously, the conical hole limits the top of the sensor 83, preventing excessive descent and potential damage to the sensing needle from contact with the bottom of the sample tube.
[0037] The working principle of the above embodiments is as follows:
[0038] The device is placed in the river. The annular float 4 and float 5 provide stable buoyancy to the chassis module 1. Driven by the impeller device 3, it can move in the water as needed until it reaches a suitable position. First, the belt drive 66 moves the transverse block 65, thereby moving the sampling cylinder 69 above the sampling port 10. Then, the screw device 62 operates, driving the transverse block 65 down via the lifting block 63 and guide rod 64 until the sampling cylinder 69 extends into the sampling port 10. The first cylinder 68 then operates, moving the push plate 610 upward, thereby drawing water samples into the sampling cylinder 69. The sampling cylinder 69 is then reset, and the device continues to move. During the movement, the linear module 9 drives the tube transfer assembly 7 forward, so that the sample tube is aligned with the sampling cylinder 69. Through the above-mentioned movement, the sampling cylinder 69 is moved down to contact the sample tube, and the water sample is introduced into the sample tube for collection. The sampling cylinder 69 collects the water sample until it reaches a suitable position. After that, the above sampling operation is repeated. The linear module 9 drives the tube transfer assembly 7 to adjust the position in coordination with the sampling reciprocating motion. At the same time, the drive motor 73 drives the double-layer baffle 74 to rotate, so that the position of the sample tube is adjusted until the sample tube is below the sensor 83. The second cylinder 82 pushes the sample tube out, moving the sensor 83 into the sample tube to complete the detection of the water sample in the sample tube. The data is then transmitted through the wireless data transmission module.
[0039] Therefore, it can achieve multi-regional sampling and testing, thereby improving the effectiveness of water quality testing, and can also store and collect water samples for further testing and analysis.
[0040] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
