DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, the device includes a mounting plate 1, a sampling tube 2 and a support plate 3. There are several sampling tubes 2, and a plurality of sampling tubes 2 are fixedly arranged at the bottom of the mounting plate 1 with the center of the mounting plate 1 as the center. The support plate 3 is fixedly sleeved on the outer lower end of the sampling tube 2, and a clearance hole 4 is integrally provided at the inner bottom end of the sampling tube 2. A U-shaped handle 5 is fixedly provided on the top of the mounting plate 1. A switching component 6 is provided on the top of the mounting plate 1. The switching component 6 includes a rotating rod 601 that rotates through the top of the mounting plate 1, and the bottom of the rotating rod 601 rotates through the support plate 3. A sealing plate 602 made of rubber is fixedly sleeved on the outer lower end of the rotating rod 601. The top surface of the sealing plate 602 is in a tightly fitting design with the bottom surface of the support plate 3. A drainage hole 603 is integrally provided on the left side of the sealing plate 602, and a filter screen 604 is fixed inside the drainage hole 603.

[0029] A one-way valve 7 is fixedly provided inside the give way hole 4, a drain pipe 8 is fixedly passed through the lower end of the outside of the sampling tube 2, a valve 9 is rotatably passed through the outside of the drain pipe 8, a limiting ring 10 is fixedly provided at the upper end of the inside of the sampling tube 2, a floating block 11 is provided on the top of the limiting ring 10, the floating block 11 is slidingly connected to the sampling tube 2, an indicator pin 12 is fixedly provided on the top of the floating block 11, and the end of the indicator pin 12 away from the floating block 11 slides through the sampling tube 2 and the mounting plate 1 in sequence, and a number of detailed bags 13 are fixedly provided on the top of the mounting plate 1, and the detailed bags 13 and the sampling tube 2 are in a one-to-one corresponding design.

[0030] First, the drainage hole 603 and the clearance hole 4 at the middle end on the left side are in a state of overlap with each other. The staff holds the handle 5 and moves the support plate 3 and the sampling tube 2 into the wastewater. The wastewater is discharged from the drainage hole 603 through the clearance hole 4 into the interior of the sampling tube 2 at the middle end on the left side. The one-way valve 7 can prevent the wastewater in the sampling tube 2 from being discharged to the outside through the clearance hole 4. The filter screen 604 can filter the impurities in the wastewater discharged into the sampling tube 2. The wastewater discharged into the sampling tube 2 passes through the limit ring 10 to form buoyancy on the float 11, so that the float 11 drives the indicator pin 12 to move out of the mounting plate 1. When the staff sees that the indicator pin 12 is moved out of the mounting plate 1, it means that the wastewater collection is completed, and then the support plate 3 is moved together with the The sampling tube 2 is taken out from the wastewater, and the relevant information card of the working point in the area where wastewater has been collected is inserted into the detailed bag 13 corresponding to the sampling tube 2. The staff then moves the device to other working points in the wastewater area, and rotates the rotating rod 601 so that the rotating rod 601 drives the sealing plate 602 to rotate, thereby making the drainage hole 603 coincide with the next makeshift hole 4, and the other makeshift holes 4 are blocked and blocked by the sealing plate 602. The staff then follows the above steps to sample the wastewater from other working points. After sampling, the staff can open the valve 9 and discharge the collected wastewater from the drainage pipe 8 into the test vessel, so as to test the liquid collected at multiple points in the wastewater area in turn.

[0031] Example 2

[0032] like Figure 2 、 Figure 3 As shown, support pins 14 are fixed on the left and right sides of the top of the mounting plate 1, and a circular plate 15 is fixed on the top of the support pin 14. The circular plate 15 is sleeved on the outside of the rotating rod 601, and connecting pins 16 are fixed on the left and right sides of the upper end of the outer side of the rotating rod 601. A circular ring 17 is fixed on the end of the connecting pin 16 away from the rotating rod 601. The circular ring 17 is sleeved on the outside of the circular plate 15, and a plurality of arc-shaped slots 18 are integrally provided inside the circular plate 15. The arc-shaped slots 18 and the sampling tube 2 are in a one-to-one correspondence design. A sliding pin 19 is slidably connected inside the circular ring 17, and the sliding pin 19 and the drainage hole 603 are in a one-to-one correspondence design. A wedge plate 20 is fixed on the inside of the sliding pin 19, and the wedge plate 20 and the arc-shaped slot 18 can be disassembled and assembled in a snap-fit manner. A spring 21 is sleeved on the outside of the sliding pin 19, and one end of the spring 21 is fixedly connected to the wedge plate 20, and the other end of the spring 21 is fixedly connected to the circular ring 17.

[0033] According to the operation method in Example 1, when the staff rotates the rotating rod 601 to make the drainage hole 603 coincide with the next clearance hole 4, the rotating rod 601 drives the connecting pin 16 together with the circular ring 17, the sliding pin 19 and the wedge plate 20 to squeeze the current corresponding arc groove 18, so that the wedge plate 20 is separated from the current corresponding arc groove 18, and the spring 21 is deformed until the wedge plate 20 coincides with the next arc groove 18. The rebound force of the spring 21 causes the wedge plate 20 to be inserted into the inside of the next arc groove 18. At this time, the state in which the drainage hole 603 and the next clearance hole 4 coincide with each other is locked.
