[0001] This utility model relates to the field of water quality monitoring, and in particular to a water quality monitoring device. Background Technology

[0002] Water quality monitoring devices typically include structures such as floating rafts, and use electricity to achieve overall sampling and operation. For example, the prior art with patent number CN105699613A discloses similar devices, which are sometimes also equipped with sampling chambers and solar panels.

[0003] However, for large-area water surface data collection, water quality monitoring devices typically require multiple sampling operations using water pumps to collect water quality data from the water surface. This process repeatedly increases power consumption, ultimately shortening the overall operating time of the device and affecting its efficiency. Therefore, to address these issues, a water quality monitoring device is provided here. Summary of the Invention

The helical shaft passes through the inside of the inclined tube to the bottom of the extension plate. The inner wall of the inclined tube has an annular groove, and a conveying pipe extends outward from the inside of the annular groove, the conveying pipe being connected to the monitoring component.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] In the attached diagram, all identical reference numerals refer to the same components.

[0024] Example 1

[0025] As shown in Figures 1-2, this utility model provides a water quality monitoring device, including a floating raft 1. A support frame 101 is installed on the top of the floating raft 1. A solar panel 102 is fixedly installed on the upper part of the support frame 101. A monitoring component 103 is fixedly installed on the inner side of the support frame 101. An extension plate 2 extends from one end of the floating raft 1. An inclined tube 3 is installed on the surface of the extension plate 2. A vertical head 4 is installed on the top of the inclined tube 3. A rotating rod 5 is rotatably connected to the inner side of the vertical head 4. A rotating blade 6 is provided on the surface of the rotating rod 5. The rotating blade 6 is used to drive the rotating rod 5 to rotate.

[0026] The inclined tube 3 includes an inclined shaft 301 inside, and a transmission shaft 501 is included inside the rotating rod 5. A spiral shaft 302 is axially connected to the bottom end of the inclined shaft 301. The spiral shaft 302 and the inclined tube 3 are inclined at 15-30 degrees. The spiral shaft 302 passes through the inside of the inclined tube 3 to the bottom of the extension plate 2. The inner wall of the inclined tube 3 is provided with an annular groove 303. A conveying pipe 7 extends from the inside of the annular groove 303 to the outside of the inclined tube 3. The conveying pipe 7 is connected to the monitoring component 103.

[0027] As shown in Figure 1, the conventional components include a floating raft 1 and a solar panel 102 on its surface. Since the monitoring component 103 of the device itself requires power, if it is equipped with IoT components, such as a wireless connection module or a GPS positioning module, the power consumption will be further increased. When water sampling or water sampling testing is required, a water pump is needed to extract the water, which further increases the power consumption, ultimately leading to a sharp increase in the overall power consumption of the device. Therefore, a thinner extension plate 2 is provided on the surface of the floating raft 1. By installing an inclined pipe 3 on the extension plate 2, the inclined pipe 3 is mainly driven by wind at the top to continuously collect water upwards along the spiral shaft 302, as shown in Figure 2. Then, the water is discharged into the detection component from the inclined conveying pipe 7 through the annular groove 303, realizing the sampling or conveying of water to complete the detection operation.

[0028] A bearing seat 304 is installed at the bottom end of the spiral shaft 302. A mesh sleeve 8 is installed on the outside of the bearing seat 304. The top of the mesh sleeve 8 is connected to the bottom surface of the extension plate 2. The mesh sleeve 8 is an arc-shaped protrusion extending downward from the bottom of the extension plate 2. The surface of the mesh sleeve 8 is provided with holes of the same size. When the bottom of the spiral shaft 302 is located inside the water, it prevents floating objects from directly wrapping around the spiral shaft 302 or directly blocking the lower part of the inclined pipe 3. The hole structure allows water to enter the inside, while dirt can be blocked on the outside.

[0029] In this embodiment, a first bevel gear 3011 is installed at the top of the inclined shaft 301, and a second bevel gear 5011 is installed at the bottom of the transmission shaft 501. The first bevel gear 3011 and the second bevel gear 5011 are meshed. The top of the transmission shaft 501 is fixedly connected to the rotating rod 5, and the bottom of the inclined shaft 301 is fixedly connected to the top of the spiral shaft 302. A collar is installed on the upper surface of the inclined shaft 301, and a fixing rod extending to the inner wall of the inclined tube 3 is provided on the surface of the collar. This allows the inclined shaft 301 and the transmission shaft 501 to drive each other mainly through bevel gears of different shapes. After the top rotating blade 6 rotates, it will drive the rotating rod 5 to transmit power from the transmission shaft 501 to the inclined shaft 301. The connection between the inclined shaft 301 and the spiral shaft 302 allows the two to rotate synchronously, achieving the effect of overall self-rotation.

[0030] The spiral shaft 302 and the inclined tube 3 are inclined away from the side of the conveying tube 7, and the conveying tube 7 is inclined towards the side of the monitoring component 103. The specific inclined structure is shown in Figure 2, so that the side of the internal annular groove 303 with a lower horizontal height is located at one end of the conveying tube 7. When the spiral shaft 302 draws water upward, the water will enter the annular groove 303 and be output from the conveying tube 7 to the inside of the detection component. The upper part of the annular groove 303 is also provided with a water outlet for controlling the water level.

[0031] A ratchet and a ratchet tooth are provided between the rotating rod 5 and the vertical head 4. The ratchet and the ratchet tooth are used to prevent the rotating rod 5 from reversing. This fixes the direction of rotation of the rotating structure, and also fixes the direction of rotation of the spiral shaft 302, so that the spiral shaft 302 can drive the water upward when it rotates.

[0032] Working principle: Since the floating raft 1 is usually self-floating or fixed to a rope, it is generally used in lakes or outdoors. The monitoring component 103 on its surface is equipped with a sample collection component or a water flow chamber to detect water quality and achieve the function of internal water quality detection.

[0033] However, prolonged use of a water pump to extract water would further increase the equipment's power consumption. Therefore, this practical floating raft 1 is extended with an extension plate 2, which is equipped with an inclined pipe 3, a vertical head 4, and a rotating rod 5. A rotating blade 6 is installed on the rotating rod 5, allowing wind energy to drive the rotating blade 6 and rotate the rotating rod 5. The rotating rod 5 then drives the first bevel gear 3011 based on the transmission shaft 501 and the second bevel gear 5011. The first bevel gear 3011 then transmits the kinetic energy from the inclined shaft 301 to the spiral shaft 302. The spiral shaft 302 is an Archimedes spiral pump, meaning that when the power is generated to drive the shaft, the water can continuously rotate upwards from the bottom. The water is moved until it falls into the annular trough 303. The water in the annular trough 303 then moves to the monitoring component 103 based on the inclined transport pipe 7. This achieves the water collection and transportation process without the need for external power equipment. Since the entire structure is external to the monitoring component 103, it is not only easy to maintain and disassemble, but also allows the internal solenoid valve to close the transport pipe 7 when not needed. At the same time, the entire device can also be used synchronously with the water pump built into the monitoring component 103. For example, when there is wind power, the water can be automatically transported to the monitoring component 103. When there is no wind power, the built-in water pump will be used to sample the water.

[0034] Example 2

[0035] The difference from Embodiment 1 is that, as shown in FIG3, the mesh sleeve 8 includes a fixing member 801 and a rotating sleeve 802, the rotating sleeve 802 and the fixing member 801 are rotatably connected, and the surface of the rotating sleeve 802 includes a grid for support.

[0036] Specifically, when there are many flexible pollutants on the water surface, they can easily get tangled on the surface of the mesh sleeve 8, such as flocculent material. Therefore, the overall kinetic energy is further extended to the rotating sleeve 802, where the bearing seat 304 is connected to the fixing part 801, as shown in Figure 2-3. The inner wall of the grid is connected to the bottom of the spiral shaft 302. So when the extension plate 2 is immersed in the water, the water submerges the upper side of the mesh sleeve 8. When the outer side of the mesh sleeve 8 encounters flocculent material or strip-shaped plants, the mesh sleeve 8 itself will also rotate, allowing the attached flocculent material to detach from the surface of the mesh sleeve 8 based on the rotation, so as to achieve the effect of avoiding pollutants at the bottom.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
