DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0019] In one embodiment, see Figure 1-Figure 4 A water quality online analysis mixing device comprises a base 1, a support frame 2 is fixedly connected to the top of the base 1, a rotating rod 7 is passed through the top of the support frame 2, the rotating rod 7 is rotatably connected to the top of the support frame 2, a circular gear 12 is fixedly connected to the upper end of the rotating rod 7, a turntable 5 is fixedly connected to the lower end of the rotating rod 7, a plurality of placement slots 6 distributed in a circle are provided on the top of the turntable 5, a motor 8 is fixed to the top of the support frame 2, an incomplete gear 11 capable of meshing with the circular gear 12 is installed at the output end of the motor 8, a lifting plate 9 is provided above the turntable 5, a branch pipe 10 is passed through the inside of the lifting plate 9, the branch pipe 10 is fixedly connected to the lifting plate 9, wherein the lifting plate 9 is connected to a lifting mechanism 4, the lifting mechanism 4 is used to drive the lifting plate 9 to move up and down, the branch pipe 10 is connected to a blowing mechanism 3, and the blowing mechanism 3 is used to blow air into the branch pipe 10.

[0020] In this embodiment, when the device analyzes the water quality, the detection cylinder containing the detection reagent and the water to be detected is placed in the placement groove 6, and the motor 8 is started at the same time. The motor 8 drives the incomplete gear 11 to rotate. While the incomplete gear 11 rotates, it drives the rotating rod 7 to rotate a certain angle through the meshing with the circular gear 12. When the detection cylinder rotates to the bottom of the branch pipe 10, the circular gear 12 is disengaged from the meshing of the incomplete gear 11. At this time, the rotating rod 7 stops rotating, and then the staff can place another detection cylinder containing the detection reagent and the water to be detected in the other placement groove. Inside the slot 6, the lifting mechanism 4 drives the lifting plate 9 to move downward while placing, so that the lower end of the branch pipe 10 extends into the water to be tested. After the lower end of the branch pipe 10 extends into the water to be tested, the blowing mechanism 3 blows air into the branch pipe 10. Since air is insoluble in water, after the air enters the water to be tested, it can stir the water to be tested and the detection reagent, thereby accelerating the mixing of the water to be tested and the detection reagent. There is no need to manually mix and stir the detection reagent and the water to be tested, which saves manpower and effectively improves the efficiency of online water quality analysis.

[0021] See also Figure 2-Figure 4 The blowing mechanism 3 includes an air pressure tube 31 arranged above the support frame 2, the air pressure tube 31 is fixedly connected to the top of the support frame 2 through a fixing seat 38, a piston 32 is arranged inside the air pressure tube 31, and the piston 32 is slidably connected to the inner wall of the air pressure tube 31, wherein the piston 32 is connected to the incomplete gear 11 through a pushing component, and when the incomplete gear 11 rotates, the piston 32 is driven to reciprocate inside the air pressure tube 31 through the pushing component, and the air pressure tube 31 is connected to an air outlet pipe 34 and an air inlet pipe 33, and the air outlet pipe 34 is connected to the branch pipe 10;

[0022] When the circular gear 12 disengages from the meshing of the incomplete gear 11, and one of the detection tubes just rotates to the bottom of the branch pipe 10, the incomplete gear 11 pushes the piston 32 through the pushing assembly, and a negative pressure is formed inside the air pressure tube 31. The air enters the air pressure tube 31 through the air inlet pipe 33. As the incomplete gear 11 continues to rotate, the pushing assembly drives the piston 32 to move in the opposite direction, squeezing the air inside the air pressure tube 31 from the piston 32. The air enters the branch pipe 10 through the air outlet pipe 34, so that the air inside the branch pipe 10 enters the water to be tested, thereby accelerating the mixing of the water to be tested and the detection reagent. In order to allow the air to move in one direction, a one-way valve is installed on the air inlet pipe 33 and the air outlet pipe 34, and in order to avoid the interference of the air outlet pipe 34 with the up and down movement of the lifting plate 9, the air outlet pipe 34 is preferably a hose.

[0023] See also Figure 3 and Figure 4 The pushing assembly includes a slide bar 35 fixedly connected to the piston 32, the slide bar 35 passes through the end of the air pressure tube 31 and is slidably connected to the end of the air pressure tube 31, and one end of the slide bar 35 located outside the air pressure tube 31 is fixedly connected to a baffle 37, and the baffle 37 is connected to the end of the air pressure tube 31 through a first spring 36, and the baffle 37 is fixedly connected to a rack 39 that can mesh with the incomplete gear 11;

[0024] When the circular gear 12 disengages from the meshing of the incomplete gear 11, the incomplete gear 11 meshes with the rack 39, thereby driving the rack 39 to move horizontally. The rack 39 drives the piston 32 to slide inside the air pressure tube 31 through the baffle 37 and the slide rod 35, and the air enters the branch pipe 10 through the intake pipe 33. When the rack 39 disengages from the meshing of the incomplete gear 11, the baffle 37 automatically resets under the action of the first spring 36, thereby driving the piston 32 to squeeze the air inside the air pressure tube 31 through the slide rod 35, so that the air can enter the branch pipe 10 through the outlet pipe 34.

[0025] See also Figure 1 and Figure 2 The lifting mechanism 4 includes a guide bar 41 fixedly connected to the lifting plate 9, the guide bar 41 passes through the top of the support frame 2 and is slidably connected to the top of the support frame 2, wherein the lifting plate 9 is connected to the top of the support frame 2 through a second spring 42, and the rack 39 is fixed with an extrusion component for extruding the guide bar 41;

[0026] While the incomplete gear 11 drives the rack 39 to move, the rack 39 squeezes the guide bar 41 through the extrusion assembly, and the guide bar 41 drives the lifting plate 9 to move downward, and the lifting plate 9 drives the branch pipe 10 to move downward, so that the lower end of the branch pipe 10 can extend into the water to be tested. When the rack 39 is out of engagement with the incomplete gear 11, the extrusion assembly no longer squeezes the guide bar 41, and the lifting plate 9 drives the branch pipe 10 upward under the action of the second spring 42. While the branch pipe 10 moves upward, the piston 32 squeezes the air inside the air pressure tube 31, so that the air enters the water to be tested, and then mixes the water to be tested and the detection reagent.

[0027] See also Figure 4 The extrusion assembly includes a push block 43 fixedly connected to the rack 39, and a slope is provided on one side of the top of the guide bar 41 close to the push block 43;

[0028] While the incomplete gear 11 drives the rack 39 to move, the rack 39 squeezes the inclined surface at the top of the guide bar 41 through the push block 43, so that the guide bar 41 can drive the lifting plate 9 to move downward, and then drive the branch pipe 10 to extend into the water to be tested.

[0029] Working principle: When the device analyzes water quality, the detection cylinder containing the detection reagent and the water to be detected is placed in the placement groove 6, and the motor 8 is started at the same time. The motor 8 drives the incomplete gear 11 to rotate. While the incomplete gear 11 rotates, it drives the rotating rod 7 to rotate a certain angle through the engagement with the circular gear 12. When the detection cylinder rotates to the bottom of the branch pipe 10, the circular gear 12 disengages from the engagement of the incomplete gear 11. At this time, the incomplete gear 11 is engaged with the rack 39, thereby driving the rack 39 to move horizontally. The rack 39 drives the piston 32 to slide inside the air pressure tube 31 through the baffle 37 and the slide rod 35, and a negative pressure is formed inside the air pressure tube 31. The air enters the air pressure tube 31 through the air inlet pipe 33, and while the rack 39 moves, it squeezes the inclined surface at the top of the guide bar 41 through the push block 43. Thereby, the guide bar 41 can drive the lifting plate 9 to move downward, and the lower end of the branch pipe 10 can be extended into the water to be tested. When the rack 39 disengages from the meshing of the incomplete gear 11, the baffle 37 and the rack 39 are automatically reset under the action of the first spring 36, and the push block 43 no longer squeezes the inclined surface of the guide bar 41. The lifting plate 9 drives the branch pipe 10 to move upward under the action of the second spring 42. While the branch pipe 10 moves upward, the piston 32 squeezes the air inside the air pressure tube 31, and the air enters the branch pipe 10 through the air outlet pipe 34, so that the air inside the branch pipe 10 enters the water to be tested, thereby accelerating the mixing of the water to be tested and the detection reagent. There is no need to manually mix and stir the detection reagent and the water to be tested, which saves manpower and effectively improves the efficiency of online water quality analysis.
