[0001] The present invention relates to the technical field of industrial sewage sampling devices, and particularly to a timing sampling device for industrial sewage and its usage method. Background Art

[0002] With the rapid development of society, the treatment of sewage has attracted more attention. In order to facilitate the sampling and preservation of industrial sewage, corresponding sampling devices are often required. However, the existing devices have the following technical deficiencies during use:

However, the positioning mechanisms adopted by the existing sampling devices are too single and the direction is fixed, and the fixing angle, usage angle, and fixing method cannot be adjusted according to the usage needs during use.

[0043] According to the usage requirements, the positioning pin 6 is pulled out from the mounting hole and the matching hole, so that the matching rotation plate 5 can be easily rotated around the positioning pin 6 until it rotates to an appropriate angle. Then, the positioning pin 6 is inserted into the inner sides of the mounting hole and the matching hole at the corresponding position, so that the adjusted usage angle is fixed, driving the cylindrical positioning module and the multi-directional clamping module 8 to be at an appropriate angle;

[0044] When the position of the fixed mounting device is cylindrical, a cylindrical positioning module is adopted. During use, the locking pin 12 is withdrawn from the connection hole between the driven snap ring 11 and the positioning snap ring 9, so that the driven snap ring 11 and the positioning snap ring 9 are separated. The cylindrical fixed position is placed inside the positioning snap ring 9. At this time, the driven snap ring 11 is reset, and the positioning snap ring 9 is used to clamp and fix the cylinder. At this time, the locking pin 12 is inserted into the connection hole between the driven snap ring 11 and the positioning snap ring 9, so that the driven snap ring 11 and the positioning snap ring 9 are fixed, and the whole device is fixed;

[0045] When the position of the fixed device is of other shapes, the first motor 14 is controlled to output torque to the driving gear 15. The driving gear 15 is used to drive the first rack 16 to perform a lateral sliding displacement, and the lateral clamping block 17 is pushed to laterally clamp and fix the fixed position. At this time, the lateral clamping block 17 is used to push the derivation shaft 18 to drive the endwise folding rod 20 to perform an endwise angular socketing, and then the endwise positioning post 21 slides on the surface of the auxiliary guiding rod 19 to complete the endwise locking and clamping of the fixed position, so that the device can easily select different fitting designs according to the design of the mounting position, thereby greatly improving the fitting adaptability and facilitating better fixation at the position where industrial sewage sampling is required.

[0049] The second motor 25 is controlled to output torque to the first gear shaft 26, and the rack column 27 is driven by the first gear shaft 26 to descend under the driving of the first gear shaft 26. The transmission base 28 is used to transmit the descent of the rack column 27 to the linkage transmission frame 32, so that the linkage transmission frame 32 drives the transmission sleeve 33 to complete the force deduction, so that the transmission sleeve 33 forms an angle adjustment during the force process, and the transmission sleeve 33 is used to deduce the sliding guide block 34 on the inner side of the built-in guide frame 31, thereby forming the adjustment of the sampling position of the timing multi-stage sampling structure 3 by the sliding guide block 34, so that the device is convenient for adjusting and deducing multiple positions on the peripheral side, thereby facilitating the expansion and reduction of the sampling range.

[0054] By controlling the third motor 38 at a fixed time to complete torque output, driving the eccentric plate 39 to rotate by the third motor 38, and using the eccentric design of the eccentric plate 39, during the rotation of the eccentric plate 39, through the connection between the guiding sleeve 41 and the pushing rod, a lifting adjustment is formed. Furthermore, the guiding sleeve 41 drives the piston push rod 43 to rise or fall inside the air pressure guiding column 42, thereby forming a suction force;

The outside of the second guiding inner frame (44) is fixedly connected with the power output box (45). The top end of the power output box (45) is fixedly connected with the fourth motor (46). The output end of the fourth motor (46) is fixedly connected with the second gear shaft (47). The second rack (48) is slidably connected to the inside of the second guiding inner frame (44). One end of the second rack (48) is meshed with the second gear shaft (47). A plurality of auxiliary loading plates (49) are fixed at the end of the second rack (48) away from the second gear shaft (47). The sampling storage tank (50) is fixedly connected to the inside of the auxiliary loading plate (49). The outside of the sampling storage tank (50) is fixedly connected with the inner adjustment frame (52). One side of the inner adjustment frame (52) is fixedly connected with the fifth motor (53) by screws. The output end of the fifth motor (53) is fixedly connected with the flip closing plate (54). The flip closing plate (54) is used to seal the sampling storage tank (50) to store samples. The top end of the sampling storage tank (50) is in contact with the bottom end of the pneumatic guiding column (42).

2. The timed sampling device for industrial sewage according to claim 1, wherein: Laser sensors (51) are fixed at the bottom end of the pneumatic guiding column (42) and the top end of the auxiliary loading plate (49). The laser sensors (51) are used to assist the alignment of the pneumatic guiding column (42) with the sampling storage tank (50).

3. A method for using a timed sampling device for industrial sewage, which uses a timed sampling device for industrial sewage according to one of claims 1 or 2 above, characterized in that: At least include the following steps: The whole device is carried to the position where sewage sampling is required by the adjustable positioning structure (1) through sampling; The timed multi-stage sampling structure (3) is pushed to multiple different sampling positions by controlling the sampling range adjustment structure (2); The timed multi-stage sampling structure (3) is controlled to complete sampling; During the sampling process, multiple different sampling storage tanks (50) are selected according to multiple sampling positions to store the samples.
