[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0024] Reference Figure 1-5 , a water quality sampling device, comprising a mounting frame 2, the mounting frame 2 being rectangular in shape and hollow inside;
[0025] Four floating plates 1, which are detachably connected to the four corners of the mounting frame 2;
[0026] A propeller 7 is connected to the center of one side of the mounting frame 2 through a mounting bracket, a mounting frame 3 is installed at the top center of the mounting frame 2, the internal rotation of the mounting frame 3 is connected to the take-up roller, the outer ring of the take-up roller is wrapped with wire, a collecting drum 4 is provided at the bottom center of the mounting frame 2, the top of the collecting drum 4 is connected to the end of the wire, a driving motor 10 is installed on one side of the mounting frame 3, and the output shaft of the driving motor 10 passes through one side of the mounting frame 3 through a bushing and is transmission-connected to the end of the take-up roller.
[0027] Furthermore, fixing rods 9 are provided at the bottom of both sides of the mounting frame 3, one end of the fixing rod 9 is fixedly connected to the side wall of the mounting frame 3, and the other end is fixedly connected to the top bolt of the mounting frame 2. The fixing rods 9 provided at the bottom of both sides of the mounting frame 3, and one end of the fixing rod 9 is fixedly connected to the side wall of the mounting frame 3, and the other end is fixedly connected to the top bolt of the mounting frame 2, enhance the connection stability between the mounting frame 3 and the mounting frame 2. During the working process, when the driving motor 10 is started and the wire-taking roller rotates to drive the wire and the collecting drum 4 to rise and fall, the fixing rod 9 can withstand part of the pulling force to prevent the mounting frame 3 from being deformed or damaged due to excessive force, thereby achieving the effect of improving the overall structural strength and stability of the device.
[0028] Furthermore, the two fixing rods 9 are made of metal, and the outer walls of the fixing rods 9 are coated with an anti-rust coating. The two fixing rods 9 are arranged at an angle. By making the two fixing rods 9 made of metal and the outer walls coated with an anti-rust coating, the metal material ensures the strength and load-bearing capacity of the fixing rods 9, and the anti-rust coating can effectively prevent the fixing rods 9 from rusting and corroding in a water environment. During the work process, even if the device is exposed to a humid or underwater environment for a long time, the fixing rods 9 can maintain good performance, thereby achieving the effect of extending the service life of the device.
[0029] Furthermore, a plurality of water inlet holes 12 are provided at the top of the collecting tube 4, and a counterweight block 11 is fixedly connected to the bottom of the collecting tube 4. Through the arrangement of the plurality of water inlet holes 12 at the top of the collecting tube 4 and the counterweight block 11 fixedly connected to the bottom, the water inlet holes 12 allow water samples to enter smoothly when the collecting tube 4 sinks, and the counterweight block 11 ensures that the collecting tube 4 can remain stable during the sinking process and is not easily affected by the water flow and deviates from the predetermined position. In the work process, such a design enables the collecting tube 4 to accurately and efficiently collect water samples of the required depth, thereby achieving the effect of improving the sampling accuracy and efficiency.
[0030] Furthermore, the four corners of the mounting frame 2 are fixedly connected with side panels 5, and the top of the floating plate 1 is fixedly connected with a positioning screw 14. The top of the side panel 5 is provided with a through hole that penetrates the side panel 5 and is compatible with the positioning screw 14. The top end of the positioning screw 14 is connected with a positioning nut 13 through the through hole. Through the side panels 5 fixedly connected at the four corners of the mounting frame 2 and the positioning screw 14 fixedly connected to the top of the floating plate 1, the through holes opened on the top of the side panel 5 are compatible with the positioning screw 14, and are fixed by the positioning nut 13, a detachable connection between the floating plate 1 and the mounting frame 2 is realized. In the work process, this connection method facilitates the assembly, disassembly and transportation of the device, while ensuring that the connection between the floating plate 1 and the mounting frame 2 is firm and reliable, thereby achieving the effect of improving the convenience and practicality of the device.
[0031] Furthermore, the diameter of the float 1 gradually expands, and the diameter of the float 1 on the side close to the side plate 5 is smaller than the diameter of the other side. The mounting bracket includes a mounting sleeve 6 connected to the bottom of one side of the mounting frame 2 through a connecting rod 8, and the propeller 7 is installed inside the mounting sleeve 6. Through the design of the gradually expanding diameter of the float 1 and the setting of the mounting sleeve 6 and the connecting rod 8 included in the mounting bracket, the diameter of the float 1 on the side close to the side plate 5 is smaller than the diameter of the other side, which helps to reduce the resistance of the water flow to the float 1 and increase the moving speed of the device, while the mounting sleeve 6 and the connecting rod 8 ensure that the propeller 7 is stably installed on the mounting frame 2. In the work process, such a design makes the device more flexible and efficient when moving in the water. At the same time, the propeller 7 can provide stable thrust, thereby achieving the effect of improving the mobility performance of the device and the sampling efficiency.
[0032] In summary, the detailed workflow of this fully optimized water sampling device is as follows: The device first relies on the detachable connection design between the four floats 1 and the four corners of the mounting frame 2. Positioning screws 14 are inserted through holes in the side panels 5 and secured with positioning nuts 13 to ensure the device's stable floating on the water surface. The floats 1 feature a gradually increasing diameter, with a smaller diameter near the side panels 5 to reduce water resistance and increase the device's speed in the water. To reach the designated sampling area, a propeller 7, mounted at the center of one side of the mounting frame 2 and securely connected to the mounting sleeve 6 via a connecting rod 8, is activated. The propeller 7 is highly waterproof and operates stably in water, providing sufficient thrust to enable the mounting frame 2 and its components to maneuver across the water surface. Once the device reaches the desired position, the propeller 7 is deactivated, and sampling is ready. At this point, the drive motor 10 on one side of the mounting frame 3 is activated. The output shaft of the drive motor 10, extending through the mounting frame 3 through a sleeve, is connected to the take-up roller, driving the take-up roller to rotate, thereby releasing or tightening the wire wrapped around its outer ring. The release of the wire causes the collecting tube 4 to sink to the desired water depth under the action of gravity, accompanied by the stable guidance of the bottom counterweight 11, and the water inlet 12 at the top of the collecting tube 4 allows the water sample to enter smoothly. After the sampling is completed, the drive motor 10 is operated in reverse to tighten the wire and lift the collecting tube 4 and the water sample to the water surface. In this workflow, the fixing rods 9 set at the bottom of both sides of the mounting frame 3 play a key role. One end of them is fixedly connected to the side wall of the mounting frame 3, and the other end is connected to the top of the mounting frame 2 by bolts, which significantly enhances the structural stability between the mounting frame 3 and the mounting frame 2. When the drive motor 10 is started and the take-up roller rotates to drive the wire and the collecting tube 4 up and down, the fixing rod 9 can withstand part of the pulling force, preventing the mounting frame 3 from being deformed or damaged due to excessive force, thereby ensuring the stability and durability of the device during the sampling process. The fixing rod 9 is made of metal and coated with an anti-rust coating. Even in a humid or underwater environment, it can maintain good performance and extend the service life of the device.
[0033] The water quality sampling device achieves the following detailed beneficial effects through a series of carefully designed components and their coordinated work: First, the combination of the float 1 and the mounting frame 2, as well as the introduction of the propeller 7, realizes the stable floating and flexible movement of the device on the water surface, significantly expanding the sampling range; secondly, the efficient waterproof design and strong thrust of the propeller 7 ensure the stability and accuracy of the device movement, and improves the convenience and efficiency of sampling; thirdly, the use of the drive motor 10 and the wire of the take-up roller to control the lifting of the collecting cylinder 4 realizes the precise control of the water sample collection depth, further improving the accuracy of sampling. performance and efficiency; in addition, the water inlet hole 12 at the top of the collecting tube 4 and the counterweight block 11 at the bottom ensure that water samples can be collected accurately and efficiently; at the same time, the detachable connection design between the float 1 and the mounting frame 2, as well as the reinforcement of the fixing rod 9, not only improve the convenience and practicality of the device, but also enhance the structural strength and stability of the device and extend its service life; finally, the entire device has a compact design, a reasonable structure, and is easy to operate and maintain, which meets the needs of large-scale or emergency water quality monitoring, provides more comprehensive and accurate data support for water quality monitoring, and demonstrates excellent performance and advantages.
