Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sampling, in particular to a sewage sampling device. Background Art

[0002] Sewage refers to discharged water that has been polluted to a certain extent and has lost its original function, but can still be used after treatment.

[0003] At present, after treating the sewage, the sewage treatment plant needs to take samples of the sewage in the sewage pool for testing. The existing sampling method is that the staff starts the motor to make the screw drive the sampling box to the depth required for sampling in the sewage, and then starts the electric cylinder to move the baffle, and makes the water inlet on the baffle correspond to the water inlet at the bottom of the sampling box. Under the action of pressure, the sewage will enter the sampling box. After the sewage is loaded, start the electronic cylinder again to move the baffle, and make the water inlet on the baffle away from the water inlet at the bottom of the sampling box, so that it can be sealed.

[0004] In the current existing technology, when sampling sewage, the sampling box is lowered to the depth required for sampling in the sewage, and then the electric cylinder is started to collect the sewage. The baffle is pushed by the electric cylinder for sealing, and the sealing effect is poor. As a result, when the sampling box enters the sewage, sewage other than the required sampling position enters the sampling box, affecting the accuracy of subsequent detection.

[0005] Therefore, a sewage sampling device is proposed to solve the above problems. Utility Model Content

[0027] During operation, in the current prior art, since the sewage is sampled by lowering the sampling box to the depth required for sampling in the sewage, and then starting the electric cylinder to collect the sewage, and the electric cylinder pushes the baffle to seal, the sealing effect is poor, which will cause the sampling box to enter the sewage. Sewage that is not at the required sampling position enters the sampling box, affecting the subsequent detection accuracy; the device is through the staff starting the motor three 5 before placing the water tank 4 into the sewage, the motor three 5 drives the rotating shaft 51 to rotate, the rotating shaft 51 drives the bevel gear one 52 to rotate, the bevel gear one 52 rotates and drives the bevel gear two 53 to rotate, the bevel gear two 53 rotates and drives the bidirectional screw rod 54 to rotate, the bidirectional screw rod 54 rotates and drives the two slide plates 55 to slide on the outside of the bidirectional screw rod 54, the sliding of the slide plate 55 drives the positioning column 56 and the sealing plug 57 to move close to the water inlet pipe 41, and the sealing plug 57 enters the water inlet pipe 41, which can seal the water inlet pipe 41 with good sealing performance, and can prevent sewage that is not at the sampling position from entering the water tank 4 due to poor sealing performance during the process of sewage entering the water tank 4, resulting in inaccurate subsequent test results; after the water tank 4 is placed in the sampling position, the staff starts the motor three 5 to move the sealing plug 57 out of the water inlet pipe 41, and the sewage will enter the water tank 4 under the action of water pressure. After the sewage in the water tank 4 is loaded, the motor three 5 is started again to make the sealing plug 57 enter the water inlet pipe 41 again, and the water tank 4 is sealed to prevent the sewage from flowing out. When the sewage needs to be taken out, the staff can open the water outlet pipe 43 to take out the sewage; the filter screen 42 fixed in the water inlet pipe 41 can isolate the garbage in the sewage to prevent impurities from entering the water tank 4.

[0028] Further, such as Figure 1 , Figure 2 and Figure 3As shown, the moving assembly includes a motor 21; the output end of the motor 21 is rotatably connected to a one-way screw rod 22, and the one-way screw rod 22 passes through one side of the connecting frame 2, and the one-way screw rod 22 is rotatably connected to the upper interior of the connecting frame 2; the outer side of the one-way screw rod 22 is slidably connected to a housing 23.

[0029] During operation, the staff starts the motor 21, which drives the one-way screw 22 to rotate. The rotation of the one-way screw 22 drives the connecting frame 2 to slide on the outside of the one-way screw 22.

[0033] During operation, the staff starts the motor 23, and the motor 23 drives the one-way screw 2 31 to rotate. The rotation of the one-way screw 2 31 drives the slider 32 to slide up or down on the outside of the one-way screw 2 31. The rise or fall of the slider 32 drives the fixed plate 34 and the water tank 4 to rise or fall, so that sewage at different depths can be sampled; through the fixed rod 35 fixedly connected in the outer shell 23, the slider 32 is slidably connected to the outside of the fixed rod 35, so that the position of the slider 32 can be fixed, and the slider 32 can be prevented from shifting.

Sewage that is not at the sampling position enters the water tank 4, causing inaccurate subsequent test results; after placing the water tank 4 into the sampling position, the staff starts the motor three 5 to move the sealing plug 57 out of the water inlet pipe 41. Under the action of water pressure, the sewage will enter the water tank 4. After the sewage in the water tank 4 is loaded, the motor three 5 is started again to make the sealing plug 57 enter the water inlet pipe 41 again to seal the water tank 4 to prevent the sewage from flowing out.
