Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Embodiment:

[0022] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a new type of double-closed-loop filtering and cleaning water intake device, including a water intake pipe 1. Mounting brackets 2 are installed at both the upper and lower ends of the water intake pipe 1. A through hole 3 runs through the middle of the mounting bracket 2. Among them,

[0023] A filter screen 5 is installed inside the through hole 3. A one-way valve mechanism is provided inside the water intake pipe 1 near the bottom end. A block groove 10 is formed on the outer side of the mounting bracket 2 located inside the water intake pipe 1. A clamping groove 11 is formed on the inner wall of the water intake pipe 1 corresponding to the block groove 10. A block 12 is arranged in the block groove 10;

[0024] A lever groove 13 is formed on the outer side of the mounting bracket 2 corresponding to the upper part of the block groove 10. A lever 14 is arranged in the lever groove 13. The end of the lever 14 is fixedly connected to the end of the block 12 through a connecting rod 15. A baffle 16 is fixedly connected to the end of the lever 14 located outside the lever groove 13. A spring 17 is sleeved on the lever 14 between the baffle 16 and the mounting bracket 2;

[0025] When it is necessary to sample the water to be detected through the water intake pipe 1, immerse the bottom end of the water intake pipe 1 below the water surface. The sampled water enters the inside of the water intake pipe 1 through the one-way valve mechanism. During the water intake process, the filter screen 5 installed at the bottom end of the water intake pipe 1 filters out impurities such as sediment in the sampled water. The filter screen 5 installed at the top end of the water intake pipe 1 blocks external impurities, preventing impurities from entering its interior through the top end of the water intake pipe 1. Through this double-closed-loop filtering and cleaning water intake device, impurities or sediment can be directly filtered during the water intake process, avoiding cleaning of sediment and other impurities after sampling, and effectively improving the working efficiency of the water intake device.

[0026] Please refer to Figures 1 to 3, a first sealing ring 4 is sleeved outside the end of the mounting bracket 2 located inside the water intake pipe 1. The mounting bracket 2 is hermetically connected to the inner wall of the water intake pipe 1 through the first sealing ring 4. The filter screen 5 installed at the bottom end of the water intake pipe 1 is made of flexible material, and the filter screen 5 installed at the top end of the water intake pipe 1 is made of hard material. After the mounting bracket 2 is installed at both ends of the water intake pipe 1, the mounting bracket 2 and the water intake pipe 1 are hermetically connected through the first sealing ring 4 to prevent impurities from entering the interior of the water intake pipe 1 through the gap between the mounting bracket 2 and the water intake pipe 1.

[0027] Please refer to Figures 1 to 3 , the one-way valve mechanism includes a bracket 6. The bracket 6 is fixedly connected to the inside of the water intake pipe 1 near the bottom end. A water passage groove 7 runs through the middle of the bracket 6. A sealing cover 8 is rotatably connected to the top of the bracket 6 corresponding to the water passage groove 7. A second sealing ring 9 is installed on the circumferential side of the bottom of the sealing cover 8 corresponding to the water passage groove 7. When taking water, the water pressure at the bottom of the water intake pipe 1 pushes open the sealing cover 8, allowing the sampled water to enter the interior of the water intake pipe 1. When lifting the upper water intake pipe 1, the water pressure inside the water intake pipe 1 pushes the sealing cover 8 back to its original position to cover the water passage groove 7, preventing the sampled water from leaking out from the bottom of the water intake pipe 1 when lifting the water intake pipe 1. The clamping block 12 is rectangular columnar, and the lower end of the clamping block 12 is curved. The baffle 16 is elastically connected to the mounting bracket 2 through a spring 17. When installing the filter screen 5, the mounting bracket 2 is inserted into the end opening of the water intake pipe 1. When the inner wall of the water intake pipe 1 abuts against the curved surface of the clamping block 12, the clamping block 12 retracts into the clamping block groove 10 against the elastic force of the spring 17. When the clamping block groove 10 is aligned with the clamping groove 11, the spring 17 drives the clamping block 12 to insert into the clamping groove 11, fixedly connecting the mounting bracket 2 and the water intake pipe 1, and thus completing the installation of the filter screen 5. When disassembly is required, the clamping block 12 is moved out of the clamping groove 11 by the baffle 16 and the pressure rod 14, and then the mounting bracket 2 and the filter screen 5 can be removed. Through the structure for quick disassembly and assembly of the filter screen 5, it is convenient to quickly disassemble and assemble the filter screen 5, and thus convenient to disassemble and clean the filter screen 5.

[0028] Working principle: For this new type of double-closed-loop filtering and cleaning water intake device, when it is necessary to sample the water to be detected through the water intake pipe 1, the bottom end of the water intake pipe 1 is immersed below the water surface, and the sampled water enters the inside of the water intake pipe 1 through the one-way valve mechanism. During the water intake process, the filter screen 5 installed at the bottom end of the water intake pipe 1 filters impurities such as sediment in the sampled water, and the filter screen 5 installed at the top end of the water intake pipe 1 blocks external impurities to prevent impurities from entering its interior through the top end of the water intake pipe 1. Through this double-closed-loop filtering and cleaning water intake device, impurities or sediment can be directly filtered during the water intake process, avoiding the need to clean sediment and other impurities after sampling, effectively improving the working efficiency of the water intake device. When taking water, the water pressure at the bottom of the water intake pipe 1 pushes open the sealing cover 8, allowing the sampled water to enter the inside of the water intake pipe 1. When lifting the upper water intake pipe 1, the water pressure inside the water intake pipe 1 pushes the sealing cover 8 back to its original position and covers the water passing groove 7, preventing the sampled water from leaking out from the bottom of the water intake pipe 1 when lifting the water intake pipe 1. When installing the filter screen 5, the mounting frame 2 is inserted into the end opening of the water intake pipe 1. When the inner wall of the water intake pipe 1 abuts against the curved surface of the clamping block 12, the clamping block 12 retracts into the clamping block groove 10 against the elastic force of the spring 17. When the clamping block groove 10 is aligned with the clamping slot 11, the spring 17 drives the clamping block 12 to insert into the clamping slot 11, fixedly connecting the mounting frame 2 and the water intake pipe 1, thus completing the installation of the filter screen 5. When disassembly is required, the clamping block 12 is driven out of the clamping slot 11 through the baffle 16 and the pressure rod 14, and then the mounting frame 2 and the filter screen 5 can be removed. Through the quick disassembly and assembly structure of the filter screen 5, it is convenient to quickly disassemble and assemble the filter screen 5, and thus convenient to disassemble and clean the filter screen 5.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
