DETAILED DESCRIPTION
[0021] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0022] Please refer to Figures 1-5As shown, a wastewater multi-sample sampling device includes a mounting shell 1. A servo motor 2 is bolted to the surface of the mounting shell 1. The output shaft of the servo motor 2 passes through the interior of the mounting shell 1 and is rotatably connected to the inner wall of its penetration point. A rotating rod 3 is fixedly connected to the output shaft of the servo motor 2. Fixing frames 4 are fixedly connected to the upper and lower parts of the surface of the rotating rod 3. Sampling bottles 5 are fixedly connected inside the fixing frames 4. The number of sampling bottles 5 is several. This facilitates multi-sample sampling by the device. A water pump 6 is bolted to the surface of the mounting shell 1. The outlet pipe of the water pump 6 is connected to an inlet pipe 7. The other end of the inlet pipe 7 is connected to the interior of the mounting shell 1. This allows the wastewater to be moved by the action of the water pump 6, thereby facilitating the sampling of multiple samples. With the cooperation of pipe 7, the sewage is moved into the interior of sampling bottle 5. When multiple samples need to be collected, the servo motor 2 can drive the rotating rod 3 to rotate the fixed frame 4, thereby rotating the unused sampling bottle 5 to the position corresponding to the inlet pipe 7, making it convenient for staff to use the device. A guide ring 14 is fixedly connected to the top of sampling bottle 5, and the surface of the guide ring 14 is slidably connected to the inner wall of the mounting shell 1. Under this action, the moving sampling bottle 5 can be guided by the guide ring 14, so that the sampling bottle 5 can be more stable when moving, and avoid the sampling bottle 5's unstable rotation affecting its position accuracy. A blocking mechanism 8 is installed in the inner cavity of sampling bottle 5, and the blocking mechanism 8 can The opening of sampling bottle 5 is blocked, preventing the wastewater collected inside from easily draining out, thus effectively improving the applicability of the device. A movable plate 9 is slidably connected to one side of the inner cavity of the mounting shell 1. A water outlet groove 10 is provided on one side of the movable plate 9, which works in conjunction with the mounting shell 1. A pusher frame 11 is fixedly connected to the bottom of the movable plate 9, and the other end of the pusher frame 11 extends through to the outside of the mounting shell 1 and is slidably connected to the inner wall of its penetration point. Push rods 12 are fixedly connected to both sides of the top of the movable plate 9. The push rods 12 work in conjunction with the blocking mechanism 8. Under this action, when the operator needs to remove the wastewater from inside the sampling bottle 5, they can push the pusher frame 11 to... The movable plate 9 can drive the push rod 12 to push the blocking mechanism 8, thereby allowing the sewage inside the sampling bottle 5 to flow out. The cooperation between the water outlet 10 and the mounting shell 1 allows the sewage to be smoothly discharged from the inside of the mounting shell 1. When the sewage does not need to be removed, the position of the movable plate 9 and the water outlet 10 can prevent sewage from easily entering the inside of the mounting shell 1. A magnet 13 is fixedly connected to one side of the surface of the mounting shell 1. The movable plate 9 is made of iron. The movable plate 9 and the magnet 13 work together. Under this action, the movable plate 9 can be limited by the action of the magnet 13, so that the movable plate 9 can be more stable when it does not need to move, and avoid the movable plate 9 being unstable and affecting the blocking and discharge effect of sewage.
[0023] The blocking mechanism 8 comprises a fixed rod 81 fixed to the bottom of the inner cavity of the sampling bottle 5, both sides of the surface of the fixed rod 81 are rotatably connected with a blocking plate 82, the blocking plate 82 is used in cooperation with the sampling bottle 5, under the action of the cooperation, the blocking plate 82 can rotate under the action of water impact force when the water pump 6 fills water into the inside of the sampling bottle 5 through the water inlet pipe 7, so that water can enter the inside of the sampling bottle 5, and when the inside of the sampling bottle 5 is not filled with water, the blocking plate 82 can return to the original position under the action of the weight of the blocking plate 82 itself and the weight of water, so as to block the opening of the sampling bottle 5, avoid the sewage in the sampling bottle 5 to be easily discharged from the inside of the sampling bottle 5, the edge of the surface of the blocking plate 82 is embedded with a counterweight 83, the counterweight 83 can increase the weight of the blocking plate 82, so that the blocking plate 82 is more convenient to reset, the bottom of the blocking plate 82 is movably connected with the surface of the push rod 12, the blocking plate 82 is used in cooperation with the push rod 12, under the action of the cooperation, the movable plate 9 drives the push rod 12 to move, so as to push the blocking plate 82, so that the sewage can be discharged from the inside of the sampling bottle 5, effectively improving the applicability of the device.
[0024] Working principle: first, the device is placed in the sewage, and when sampling is needed, the worker starts the water pump 6 to make the sewage enter the inside of the sampling bottle 5 through the water inlet pipe 7, after sampling is completed, the water pump 6 is closed, under the cooperation of the counterweight 83, the blocking plate 82 can block the opening of the sampling bottle 5, then the servo motor 2 is started, under the action of the servo motor 2, the fixed frame 4 drives the sampling bottle 5 to rotate through the rotating rod 3, so that the sampling bottle 5 at the corresponding position of the water inlet pipe 7 is in an empty bottle state, then when sampling is needed, the water pump 6 is used to sample, and when the sewage is taken out after sampling is completed, the worker can push the push frame 11 to make it move through the movable plate 9 to drive the push rod 12, so that the blocking plate 82 rotates and no longer blocks the sewage, then the sewage flows out from the inside of the sampling bottle 5 and is discharged from the inside of the installation shell 1 under the action of the water outlet groove 10, then the worker can collect the sampling water separately.
