[0002] Automatic water quality analyzers are intelligent devices that can automatically collect, analyze, and process physical, chemical, and biological parameters in water bodies. They feature full automation from sampling to data output, high degree of automation, high accuracy, and adaptability to complex environments. They are used in wastewater treatment plants and environmental monitoring stations to monitor water quality compliance in real time.

[0003] In practical use, the inner wall of the water sample reaction tank of existing automatic water quality analyzers needs to be manually wiped and cleaned, which is time-consuming, labor-intensive, and the inner wall and bottom of the water sample reaction tank cannot be thoroughly cleaned, resulting in poor cleaning effect. A cleaning structure for automatic water quality analyzers is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings and defects in the existing technology, this utility model proposes a cleaning structure for an automatic water quality analyzer, which solves the technical problem that in the actual use of the existing automatic water quality analyzer, the inner wall of the water sample reaction tank needs to be manually wiped and cleaned, which is time-consuming, labor-intensive, and the inner walls and bottom of the water sample reaction tank cannot be thoroughly cleaned, resulting in poor cleaning effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning structure for an automatic water quality analyzer includes a water sample reaction tank. L-shaped seats are located on both the left and right sides of the center of the water sample reaction tank. Two hydraulic cylinders are fixedly installed on the side walls at both ends of the center of the water sample reaction tank. The piston rods of the four hydraulic cylinders are all vertically upward. The upper ends of the piston rods of the two hydraulic cylinders on the same side are fixedly connected to the lower end of the horizontal section of one of the L-shaped seats. A driving assembly is located at the upper end of the horizontal section of the right-side L-shaped seat. A common shifting mechanism is penetrated through the opposite side walls of the vertical sections of the two L-shaped seats. The driving assembly is kinetically connected to the shifting mechanism. A cleaning assembly is installed on the shifting mechanism, and the cleaning assembly is positioned close to the inner wall of the water sample reaction tank.

[0007] Preferably, the drive assembly includes a servo motor fixedly mounted on the upper end of the horizontal section of the right L-shaped seat, and a drive wheel is coaxially fixedly connected to the drive shaft of the servo motor. The drive wheel is connected to the displacement mechanism via a transmission connection.

[0008] Preferably, the displacement mechanism includes rotating rods that rotatably pass through the opposite sidewalls of the vertical sections of two L-shaped seats. Both rotating rods are located near the upper end of the vertical section of the L-shaped seat. The same coupling is fixedly connected to the opposite sidewalls of the two rotating rods. The same lead screw is fixedly connected between the two couplings. A driven wheel is coaxially fixedly connected to one end of the right rotating rod located on the right L-shaped seat. The driving wheel and the driven wheel are connected by belt drive. A displacement block is threaded onto the lead screw. The cleaning component is located at the lower end of the displacement block.

[0009] Preferably, the same limiting rod is fixedly connected to the opposite sidewalls of the two vertical sections of the L-shaped seat, and the limiting rod is located directly below the lead screw and horizontally passes through the displacement block.

[0010] Preferably, the cleaning component includes a U-shaped bracket fixedly connected to the lower end of the displacement block, and the same U-shaped scraper is fixedly connected to the vertical sidewalls on both sides of the U-shaped bracket. The vertical sidewalls on both sides of the U-shaped scraper are closely attached to the inner wall of the water sample reaction tank, and the lower end of the horizontal section of the U-shaped scraper is closely attached to the bottom of the water sample reaction tank.

[0011] Preferably, the U-shaped bracket is a corrosion-resistant alloy product, and the U-shaped scraper is a corrosion-resistant rubber product.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The servo motor drives the lead screw to rotate, which in turn drives the threaded displacement block to move horizontally under the limiting action of the limit rod. The displacement block, together with the U-shaped bracket, drives the U-shaped scraper made of corrosion-resistant rubber to clean the water sample reaction tank. No manual wiping and cleaning is required, saving time and effort and reducing labor intensity.

[0014] 2. The U-shaped scraper is driven to move vertically up and down by a hydraulic cylinder in conjunction with an L-shaped seat, a shifting block, and a U-shaped bracket, so that the U-shaped scraper can thoroughly clean the inner wall and bottom of the water sample reaction tank, thereby improving the cleaning effect.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A cleaning structure for an automatic water quality analyzer includes a water sample reaction tank 1. L-shaped seats 2 are located on both the left and right sides of the center of the water sample reaction tank 1. Two hydraulic cylinders 3 are fixedly installed on the side walls of both ends of the center of the water sample reaction tank 1. The piston rods of the four hydraulic cylinders 3 are all vertically upward. The upper ends of the piston rods of two hydraulic cylinders 3 on the same side are fixedly connected to the lower end of the horizontal section of one of the L-shaped seats 2. During cleaning, the hydraulic cylinders 3, in conjunction with the shifting block 9 and the U-shaped bracket 11, can drive the U-shaped scraper 12 to move vertically up and down, allowing the U-shaped scraper 12 to thoroughly clean the inner wall and bottom of the water sample reaction tank 1, improving the cleaning effect. A drive assembly is located at the upper end of the horizontal section of the right L-shaped seat 2. The drive assembly includes a servo motor 4 fixedly installed at the upper end of the horizontal section of the right L-shaped seat 2. A drive wheel is coaxially fixedly connected to the drive shaft of the servo motor 4. The drive wheel is connected to the shifting mechanism via a transmission connection. The servo motor 4 drives the drive wheel (not shown in the figure) at the drive end to rotate.

[0025] A single shifting mechanism is installed through the opposite sidewalls of the vertical sections of the two L-shaped seats 2. The drive assembly is connected to the shifting mechanism. The shifting mechanism includes rotating rods 5 that rotate horizontally through the opposite sidewalls of the vertical sections of the two L-shaped seats 2. Both rotating rods 5 are located near the upper end of the vertical section of the L-shaped seat 2. A coupling 6 is fixedly connected to the opposite sidewalls of the two rotating rods 5. A lead screw 7 is fixedly connected between the two couplings 6. A driven wheel 8 is coaxially fixedly connected to one end of the right rotating rod 5 located on the right side of the L-shaped seat 2. The driving wheel and the driven wheel 8 are connected by a belt drive. The rotation of the wheel (not shown in the figure) drives the driven wheel 8 connected by the belt drive to rotate, and the rotation of the driven wheel 8 drives the right rotating rod 5 connected by the coaxial shaft to rotate, so that the two rotating rods 5 cooperate with the coupling 6 to drive the lead screw 7 to rotate. The lead screw 7 is threaded with a displacement block 9. The cleaning component is set at the lower end of the displacement block 9. The same limiting rod 10 is fixedly connected to the opposite side wall of the vertical section of the two L-shaped seats 2. The limiting rod 10 is located directly below the lead screw 7 and is set horizontally through the displacement block 9. The rotation of the lead screw 7 drives the threaded displacement block 9 to move and adjust horizontally under the limiting action of the limiting rod 10.

[0026] The shifting mechanism is equipped with a cleaning component, which is set close to the inner wall of the water sample reaction tank 1. The cleaning component includes a U-shaped bracket 11 fixedly connected to the lower end of the shifting block 9. The same U-shaped scraper 12 is fixedly connected to the vertical side wall of both sides of the U-shaped bracket 11. The vertical side wall of both sides of the U-shaped scraper 12 is set close to the inner wall of the water sample reaction tank 1. The lower end of the horizontal section of the U-shaped scraper 12 is set close to the bottom of the water sample reaction tank 1. The shifting block 9, in conjunction with the U-shaped bracket 11, drives the U-shaped scraper 12 made of corrosion-resistant rubber to clean the water sample reaction tank 1. There is no need for manual wiping and cleaning, which saves time and effort and reduces labor intensity. The U-shaped bracket 11 is made of corrosion-resistant alloy and the U-shaped scraper 12 is made of corrosion-resistant rubber.

[0027] In use, this invention activates four hydraulic cylinders 3 arranged in pairs on the side wall of the water sample reaction tank 1. These cylinders drive two L-shaped seats 2 vertically downwards until the two L-shaped seats 2, in conjunction with the shifting block 9 and the U-shaped bracket 11, lower the U-shaped scraper 12 into the water sample reaction tank 1. Then, the servo motor 4 on the right-side L-shaped seat 2 activates the drive wheel (not shown in the figure) at the drive end, causing it to rotate. This rotation drives the driven wheel 8, which is connected by a belt drive, to rotate. The driven wheel 8 then drives the coaxially connected right-side rotating rod 5 to rotate, causing the two rotating rods 5... The coupling 6 drives the lead screw 7 to rotate. At this time, the rotation of the lead screw 7 drives the threaded displacement block 9 to move horizontally under the limiting action of the limiting rod 10. The displacement block 9, together with the U-shaped bracket 11, drives the U-shaped scraper 12 made of corrosion-resistant rubber to clean the water sample reaction tank 1. There is no need for manual wiping and cleaning, saving time and effort and reducing labor intensity. During the cleaning process, the hydraulic cylinder 3 can be used in conjunction with the displacement block 9 and the U-shaped bracket 11 to drive the U-shaped scraper 12 to move vertically up and down, so that the U-shaped scraper 12 can fully clean the inner wall and bottom of the water sample reaction tank 1, improving the cleaning effect.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
