[0005] The effect achieved by the above components is: before it is necessary to sample the sewage, first mark the unused marking plates with unused Arabic numerals in sequence. When it is necessary to sample the sewage, first move the cart to the side of the river and turn the Z-shaped handle. The Z-shaped handle rotates with the reel and the circular plate, and the circular plate rotates with the limit buckle. When the limit buckle moves to the limit slot position of the turntable, the limit buckle rotates with the turntable, and the sampler is moved to the river surface. At this time, observe the number marked on the top marking plate, and then continue to rotate the Z-shaped handle, the circular plate and the turntable continue to rotate, and the sampler enters the interior of the river. After moving to the appropriate depth, the staff then observes the number on the marking plate above the turntable, and obtains the depth of the sampler in the river through simple calculations. Then the sampler opens the water inlet of the sampler through the solenoid valve, and the sewage enters the interior of the sampler through the water inlet. Finally, the solenoid valve on the sampler is closed. The observation device achieves the effect of facilitating the staff to accurately locate the depth of the sampler in the sewage, allowing the staff to sample sewage at a fixed depth, thereby improving the practicality of the sampler.

[0011] The effect achieved by the above components is: by setting the arc plate of the circular plate to move in the arc groove of the turntable, the turntable is limited, thereby preventing the turntable from shaking when the limit buckle is not inserted into the limit groove.

[0012] Preferably, fixing devices are provided on both sides of the cart, and the fixing devices include two pads, and the two pads are respectively fixedly connected to the two sides of the cart, and the surfaces of the pads are threadedly connected with a screw, and one end of the screw is rotatably connected to a movable plate.

The fixing device achieves the effect of fixing the cart, thereby preventing the cart from shaking during work and improving the stability of the cart.

[0014] Preferably, one end of the screw rod away from the movable plate is fixedly connected to a control block, and the surface of the control block is provided with anti-slip grooves.

[0015] The effect achieved by the above components is: by setting the control block, the contact area between the staff's hand and the screw is increased, thereby making it easier for the staff to rotate the screw, bringing convenience to the staff.

[0017] The effect achieved by the above components is: by setting the telescopic rod, it is convenient for the staff to limit the moving direction of the movable plate, thereby preventing the movable plate from rotating.

[0018] Preferably, a plurality of sharp protrusions are fixedly connected to a side of the movable plate away from the screw rod, and the tips of the sharp protrusions are away from the movable plate.

[0019] The effect achieved by the above components is: by setting the pointed protrusions to be inserted into the soil, the movable plate is fixed to prevent the movable plate from sliding against the ground.

[0020] In summary, the beneficial effects of the utility model are:

[0021] Before sampling sewage, first mark unused marking plates with unused Arabic numerals in sequence. When sampling sewage, first move the cart to the side of the river and turn the Z-shaped handle. The Z-shaped handle rotates with the reel and the circular plate, and the circular plate rotates with the limit buckle. When the limit buckle moves to the limit slot position of the turntable, the limit buckle rotates with the turntable, and moves the sampler to the river surface. At this time, observe the number marked on the top marking plate, and then continue to turn the Z-shaped handle. The circular plate and the turntable continue to rotate, and the sampler enters the interior of the river. After moving to the appropriate depth, the staff then observes the number on the marking plate above the turntable, and obtains the depth of the sampler in the river through simple calculations. The sampler then opens the water inlet of the sampler through the solenoid valve, and the sewage enters the interior of the sampler through the water inlet. Finally, the solenoid valve on the sampler is closed. The observation device facilitates the staff to accurately locate the depth of the sampler in the sewage, allowing the staff to sample sewage at a fixed depth, thereby improving the practicality of the sampler.

Before sampling sewage, unused marking plates 76 are marked with unused Arabic numerals in sequence. When sampling sewage, cart 1 is first moved to the riverside and Z-shaped handle 73 is turned. Z-shaped handle 73 rotates winding shaft 3 and circular plate 71, circular plate 71 rotates limiting buckle 72. When limiting buckle 72 moves to the limiting groove 75 position of rotating disk 74, limiting buckle 72 rotates rotating disk 74, and sampler 6 is moved to the river surface. At this time, the number marked on the uppermost marking plate 76 is observed, and then Z-shaped handle 73 is continued to be turned. Circular plate 71 and rotating disk 74 rotate. 4 continues to rotate, and the sampler 6 enters the interior of the river. When it moves to the appropriate depth, the staff then observes the number on the mark plate 76 above the turntable 74, and obtains the depth of the sampler 6 in the river water through simple calculation. Then the sampler 6 opens the water inlet of the sampler 6 through the electromagnetic valve, and the sewage enters the interior of the sampler 6 through the water inlet. Finally, the electromagnetic valve on the sampler 6 is closed, and the observation device 7 is used to facilitate the staff to accurately locate the depth of the sampler 6 in the sewage, so that the staff can sample sewage at a fixed depth, thereby improving the practicality of the sampler 6.

[0029] Reference Figure 1-4 As shown, the surface of the Z-shaped handle 73 is covered with a rubber sleeve 710, and the surface of the rubber sleeve 710 is provided with anti-skid patterns. By setting the rubber pad, the effect of facilitating the staff to rotate the Z-shaped handle 73 is achieved, which brings convenience to the staff.

The side of the pad 81 close to the movable plate 83 is fixedly connected with a telescopic rod 85, and one end of the telescopic rod 85 is fixedly connected to the movable plate 83. By setting the telescopic rod 85, the effect of facilitating the staff to limit the moving direction of the movable plate 83 is achieved, so as to prevent the movable plate 83 from rotating. The side of the movable plate 83 away from the screw 82 is fixedly connected with a plurality of sharp protrusions 84, and the tip of the sharp protrusion 84 is away from the movable plate 83.

When sampling sewage, first move the cart 1 to the riverside and turn the Z-shaped handle 73. The Z-shaped handle 73 rotates with the reel 3 and the circular plate 71, and the circular plate 71 rotates with the limit buckle 72. When the limit buckle 72 moves to the limit slot 75 position of the turntable 74, the limit buckle 72 rotates with the turntable 74, and moves the sampler 6 to the river surface. At this time, observe the numbers marked on the top marking plate 76 and the position of the Z-shaped handle 73 on the scale 79, and then continue to rotate the Z-shaped handle 73, the circular plate 71 and the turntable 74. The disk 74 continues to rotate, and the sampler 6 enters the interior of the river. After moving to the appropriate depth, the staff then observes the numbers on the marking plate 76 above the turntable 74 and the position of the Z-shaped handle 73 on the scale 79, and obtains the depth of the sampler 6 in the river water through simple calculations. Then the sampler 6 opens the water inlet of the sampler 6 through the solenoid valve, and the sewage enters the interior of the sampler 6 through the water inlet. Finally, the solenoid valve on the sampler 6 is closed, and the observation device 7 is used to facilitate the staff to accurately locate the depth of the sampler 6 in the sewage, allowing the staff to sample sewage at a fixed depth, thereby improving the practicality of the sampler 6.

[0033] After the cart 1 is moved to the river bank, the control block 86 is rotated, and the control block 86 rotates with the screw 82, and the screw 82 moves the moving plate 83 toward the ground, and finally the moving plate 83 with the pointed protrusion 84 is inserted into the soil, thereby achieving the effect of fixing the cart 1. The fixing device 8 achieves the effect of fixing the cart 1, thereby preventing the cart 1 from shaking during operation and improving the stability of the cart 1.
