Description

Technical Field

[0001] This invention relates to the field of water quality monitoring device technology, and in particular to a water quality monitoring device with multi-channel water sample collection and distribution. Background Technology

[0002] A water quality monitoring device with multiple water sample collection and distribution channels is mainly used for real-time monitoring of water quality indicators, such as dissolved oxygen, pH value, turbidity, ammonia nitrogen, heavy metals and other important water quality parameters. This device is usually equipped with multiple water sample collection channels.

[0003] However, existing technologies still face some challenges when monitoring larger bodies of water, especially those with large waves. In these environments, due to the volatility and complexity of the water, water sampling devices are easily affected by water flow and waves. Especially when the waves are high or the current is rapid, the water sampling devices may be subjected to violent shaking or water flow impact, making sampling difficult. In addition, waves and water flow may cause water to flow back into the monitoring device, affecting the sampling accuracy and even causing equipment damage or malfunction. The adaptability of existing technologies in such environments still needs to be further optimized to ensure the reliability of monitoring data and the stability of the equipment.

[0004] Chinese patent document CN220603041U discloses an intelligent multi-channel water sampling device, including: a power supply winding and control unit, a measurement and sampling unit, and a power unit.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 , Figure 2 and Figure 3As shown, a water quality monitoring device with multi-channel water sample collection and distribution includes four ring-shaped outer frames 1. The upper part of the outer surface of the four outer frames 1 is fixedly connected to a ring-shaped airbag 2. The upper and lower parts of the four outer frames 1 are both fixedly connected to an arc-shaped frame 3 in a ring-shaped array on the side that is close to each other. The upper and lower parts of the four outer frames 1 near the inner side are both fixedly connected to an L-shaped frame 4. The lower end of the four L-shaped frames 4 at the top and the upper end of the four L-shaped frames 4 at the bottom are both fixedly connected to a circular plate 5. The two circular plates 5 are both fixedly installed at the ends that are close to each other. The outer surface of the drive mechanism 6 is threaded with a monitoring mechanism 7.

[0022] Furthermore, counterweights 11 are fixedly installed at the lower ends of the four outer frames 1.

[0023] During use, the entire device is placed in seawater. The drive mechanism 6 is then controlled to operate the monitoring mechanism 7. While the monitoring mechanism 7 is operating, it continuously injects seawater into its interior for exchange. Regardless of the direction of water intake, seawater can enter the inner cavity of the monitoring mechanism 7. Due to the high fluidity of seawater, the monitoring mechanism 7 can continuously pump seawater into the area and monitor it. The monitored seawater is then ejected upwards by the monitoring mechanism 7 and does not return to the monitoring mechanism 7. Therefore, by the cooperation of the drive mechanism 6 and the monitoring mechanism 7, it is possible to monitor waters with large waves and large areas. After the entire device is used, the drive mechanism 6 can open the monitoring mechanism 7 to discharge any remaining seawater inside the monitoring mechanism 7. Furthermore, this solution uses counterweights 11 fixedly installed at the lower ends of the four outer frames 1. Under the influence of the weight and mass of the counterweights 11, the entire device can always maintain a vertical state in the water, thereby improving the overall monitoring efficiency.

[0024] The annular airbag 2 mentioned above is a conventional setting in the prior art. In this solution, it is only necessary to ensure that the gas inside is sufficient to support the entire device to float on the sea surface. The inflation and deflation methods of the gas are conventional designs in the prior art, so this solution will not elaborate on them.

[0025] Example 2, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the drive mechanism 6 includes a mounting post 61 that is fixedly connected to one end of two circular plates 5 that are close to each other. The mounting post 61 has a mounting groove 62 at its lower end. A servo motor 63 is fixedly connected to the top wall of the mounting groove 62. The output end of the servo motor 63 extends through the upper end of the lower circular plate 5 to the outside and is fixedly connected to a threaded rod 64. A threaded sleeve 65 is threaded to the outer surface of the threaded rod 64. A cross rod 66 is fixedly connected to the lower end of the threaded sleeve 65. A guide rod 67 is fixedly connected to the middle of the horizontal part of the upper end of the cross rod 66. The upper ends of the four guide rods 67 extend through the lower end of the lower circular plate 5 to the outside. A blocking mechanism 68 is fixedly installed on the inner arc surface of the four arc-shaped frames 3 on the lower side. A signal transmitter 60 is fixedly connected to the middle of the upper end of the upper circular plate 5.

[0026] Furthermore, the four blocking mechanisms 68 include a hollow plate 681 fixedly connected to the inner arc surface of the arc frame 3, a main cylinder 682 slidably connected to the inner surface of the hollow plate 681, a rotating mechanism 683 fixedly connected to the lower end of the main cylinder 682, a connecting rod 684 fixedly connected to the output end of the rotating mechanism 683, and a hexagonal block 685 fixedly connected to the upper end of the connecting rod 684.

[0027] Furthermore, the lower outer surfaces of the four main tubes 682 are all fixedly connected to the ends of the cross rods 66 that are close to each other via connecting rings.

[0028] Furthermore, the monitoring mechanism 7 includes four water inlet cylinders 71. Each of the four water inlet cylinders 71 has a support plate 72 fixedly connected to the lower edge of its inner surface. Each of the four support plates 72 has a connecting rod 73 rotatably connected to its upper center. Each of the four connecting rods 73 has a flow-disrupting mechanism 74 fixedly installed at its upper end. Each of the four flow-disrupting mechanisms 74 has a water conveying mechanism 75 fixedly installed on its upper outer surface. Each of the four water inlet cylinders 71 has a horizontal plate 70 fixedly connected to its upper inner surface. Each of the four water inlet cylinders 71 has a flow-guiding component 76 fixedly installed on the outer surface of its outer surface near the outside. Each of the four water inlet cylinders 71 has a water-blocking component 77 fixedly installed at its upper end. The upper end of the connecting rod 684 on the same side passes through the lower end of the support plate 72 on the same side.

[0029] Furthermore, the lower ends of the four water inlet cylinders 71 are threadedly connected to the upper end of the hollow plate 681.

[0030] Furthermore, the four aerodynamic mechanisms 74 include four transmission rods 741. The lower ends of the four transmission rods 741 are fixedly connected to the upper ends of the connecting rods 73 on the same side. Four arc-shaped aerodynamic plates 742 are fixedly connected to the outer surfaces of the four transmission rods 741 in a circular array. The lower middle part of the four transmission rods 741 and the lower end of the connecting rods 73 on the same side are provided with interconnected hexagonal grooves 743. The hexagonal grooves 743 on the same side cooperate with the hexagonal blocks 685 on the same side.

[0031] Furthermore, the four water conveying mechanisms 75 include four rotating rods 751. The upper ends of the four rotating rods 751 are rotatably connected to the lower ends of the horizontal plates 70 on the same side. Three mounting cylinders 752 are fixedly connected to the outer surfaces of the four rotating rods 751 in a linear array. Several turbine blades 753 are fixedly connected to the outer surfaces of the three mounting cylinders 752 on the same side in a ring array. Two monitoring instruments 754 are fixedly connected to the outer surfaces of the four rotating rods 751 in a linear array. The two monitoring instruments 754 on the same side are located on the side where the three mounting cylinders 752 are close to each other.

[0032] Furthermore, the four flow guiding components 76 include four water inlet shells 761. The four water inlet shells 761 are all fixedly connected to the lower part of the outer side of the water inlet cylinder 71 on the same side and communicate with the inner cavity of the water inlet cylinder 71 on the same side. The bottom wall and top wall of the four water inlet shells 761 are all fixedly connected with flow guiding blocks 762. The four flow guiding blocks 762 are all arranged in a triangular shape.

[0033] Furthermore, the four water-proof components 77 include four annular main plates 771, each with an annular secondary plate 772 fixedly connected to its lower end. The outer surfaces of the four annular secondary plates 772 are respectively fixedly connected to the upper part of the inner surface of the water inlet cylinder 71 on the same side. Each of the four annular main plates 771 has an annular secondary plate 773 fixedly connected to its upper middle part. The inner arc surface of each of the four annular secondary plates 773 and the side of the upper end of the annular main plate 771 on the same side that is close to each other are each fixedly connected to four valves 774 in an annular array.

[0034] During use, the entire device can be lifted by sequentially attaching the hooks of the existing technology to the outer surfaces of the four arc-shaped frames 3 located on the upper side. After the device is lifted, it is placed in seawater. When the device is placed in seawater, under the action of the annular airbag 2, the upper sides of the four water inlet cylinders 71 can float on the seawater surface and a part of them can be exposed above the water surface. Then, by activating the four rotating mechanisms 683, the output end of the rotating mechanism 683 drives the connecting rod 684 on the same side to rotate through the coupling. When the connecting rod 684 rotates, since the upper end of the connecting rod 684 passes through the support plate 72 on the same side, and the hexagonal block 685 fixedly connected to its upper end is located in the inner cavity of the hexagonal groove 743 on the same side, it can simultaneously drive the transmission rod 741 and the connecting rod 73 to rotate. When the transmission rod 741 rotates, the arc-shaped baffle 742 fixedly connected to its surface also rotates. Since the water inlet shell 761 is fixedly connected to the outer surface of the water inlet cylinder 71, and the guide block 762 fixedly connected to the inner surface of the water inlet shell 761 is arranged in a triangular shape, when the four arc-shaped baffles 742 on the same side rotate, seawater will continuously flow into the water inlet cylinder 71 on the same side through the gap between the guide block 762 and the water inlet shell 761. When seawater enters the inlet cylinder 71 through the inlet shell 761, the lower end of the rotating rod 751 is fixedly connected to the upper end of the transmission rod 741. Therefore, the transmission rod 741 on the same side can rotate at the lower end of the horizontal plate 70 on the same side. When the rotating rod 751 rotates with the transmission rod 741, the rotating rod 751 on the same side will drive the mounting cylinder 752 fixedly connected to its outer surface to rotate. Therefore, the mounting cylinder 752 can drive the turbine blades 753 fixedly connected to its outer surface to rotate. Since the turbine blades 753 are inclined... The arrangement is such that the helical surface of several turbine blades 753 is like a constantly rotating "inclined plane". When this inclined plane sweeps across the water flow, it will give the water a force along the direction of the inclined plane. Since the several turbine blades 753 are restricted to rotating laterally within the water inlet cylinder 71, the water cannot easily move laterally. This force is decomposed. One part of the force makes the water rotate, and the other part of the force pushes the water upward along the axial direction of the water inlet cylinder 71. The continuous pushing of several turbine blades 753 forms a continuous upward flow in the water inlet cylinder 71. When water enters the inlet tube 71, the monitoring instrument 754 on the same side will monitor the water quality in real time, and then transmit the detected data to the signal transmitter 60, which will then transmit it to the receiver on the shore. Furthermore, as the water flowing upwards into the inlet cylinder 71, it passes under the four valves 774. Under the pressure of the upward-pushing water and atmospheric pressure, the four valves 774 open simultaneously. The water can then be discharged outwards through the openings of the four valves 774 on the same side. However, the flow direction of the seawater on the surface is opposite to the design direction of the valves 774, so the four valves 774 will automatically close, preventing the seawater from flowing backwards into the inlet cylinder 71. The specific principle is as follows: The opening and closing of the four valves 774 are driven by the pressure difference. When the pressure difference is large enough and exceeds the opening threshold of the four valves 774, the four valves 774 will open upward to allow water to be discharged upward. When the pressure difference decreases to a certain extent and is lower than the closing threshold of the four valves 774, the four valves 774 will automatically close to prevent seawater from flowing back into the water inlet tube 71. After monitoring the water in the area, the entire device is pulled out of the water by controlling the mechanism of the connecting hook. Then, the four counterweights 11 are placed facing the ground. During this process, some water remains inside the four water inlet cylinders 71. At this time, the servo motor 63 can be started, so that the output end of the servo motor 63 drives the threaded rod 64 fixedly connected to it to rotate through the coupling. When the threaded rod 64 rotates, because its outer surface is threadedly connected to the threaded sleeve 65, and the cross rod 66 fixedly connected to the lower end of the threaded sleeve 65 is limited by the four guide rods 67 to the circular plate 5 located on the lower side. On the inside, when the threaded rod 64 rotates, the four guide rods 67 can drive the cross rod 66 fixedly connected to its lower end to move downward. When the threaded sleeve 65 moves downward with the cross rod 66, since the lower part of the outer surface of the four main cylinders 682 is fixedly connected to the end of the cross rod 66 that is close to each other through the connecting ring, the four main cylinders 682 move downward with the cross rod 66. At this time, the lower end of the water inlet cylinder 71 is no longer blocked by the main cylinder 682 and the upper end of the rotating mechanism 683, and the hexagonal block 685 on the same side disengages from the hexagonal groove 743 on the same side. The remaining water will flow out from the lower end of the water inlet cylinder 71. When it is necessary to disassemble the water inlet cylinder 71 later, since the lower ends of the four water inlet cylinders 71 are respectively threaded to the upper ends of the four hollow plates 681, it is only necessary to rotate the bottle body of the water inlet cylinder 71 to remove the water inlet cylinder 71 and its internal structure at the same time.

[0035] The hooks and the mechanism that drives the hooks to lift the entire device are conventional settings in the prior art. In this solution, it is only necessary to ensure that the hooks are hooked sequentially on the outer surfaces of the four arc-shaped frames 3 on the upper side and that the entire device can be lifted. The specific shape, installation method, circuit connection method, and control method are all conventional designs and can be adjusted according to actual production needs and usage requirements. Therefore, this solution will not elaborate on them in detail.

[0036] The monitoring instrument 754 and signal transmitter 60 mentioned above are conventional settings in the prior art. In this solution, it is only necessary to monitor the collected water sample and then transmit the monitored data to the receiver on the ground through the signal transmitter 60. The specific monitoring process and method are conventional designs in the prior art. The specific installation method, circuit connection method and control method are also conventional designs. Therefore, this solution will not elaborate on the working principle of the monitoring instrument 754, signal transmitter 60 and receiver.

[0037] The aforementioned rotating mechanism 683 is specifically composed of a housing, a motor, and a coupling. In this solution, it is only necessary to ensure that the output end of the motor is fixedly connected to the connecting rod 684 via the coupling, and that the connection between the housing and the motor is waterproofed. The specific waterproofing measures are all conventional settings in the prior art, so this solution will not elaborate on them further.

[0038] It should be noted that the specific installation method, circuit connection method, and control method of the guide rod 67 used in this invention are all conventional designs, and will not be described in detail in this invention.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
