The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Example 1: Figure 1-3 , including a sampling barrel 100, a sampling assembly is slidably installed on the inner wall of the sampling barrel 100, and the sampling assembly includes an electric telescopic rod 200, the inner wall of the sampling barrel 100 is slidably connected to a piston 250, and a sealing ring 251 is fixedly installed on the outer wall around the piston 250, the top outer wall of the piston 250 and the bottom outer wall of the electric telescopic rod 200 are detachably connected through threads, and the bottom outer wall of the sampling barrel 100 is detachably connected to a float 300.

The two ends of the traction rope 310 are respectively matched and fixedly connected with the bottom of the float 300 and the top of the threaded rod 320, and then the threaded rod 320 is threadedly fixedly connected with the threaded seat 141 at the top of the support seat 140, and then the pull rope 240 is connected to the clamping seat 230, and the sampling tube 100 is placed in the wastewater pool to be used. Under the action of gravity, the sampling tube 100 falls into the wastewater. Due to the action of the float 300, when the float 300 is pulled by the bottom of the sampling tube 100, the float 300 floats on the water surface. After the sampling tube 100 sinks to a depth equal to the height of the traction rope 310, it stops sinking.

[0025] Example 2: Figure 4 The sampling tube 100 is provided with visual windows 110 on the outer walls thereof. A water sampling needle 120 is fixedly connected to the center of the bottom outer wall of the sampling tube 100. A tripod 130 is fixedly installed on the top outer wall of the sampling tube 100. The electric telescopic rod 200 is installed on the inner wall of the tripod 130. The top outer wall of the electric telescopic rod 200 is fixedly connected to a controller 210. The top of the controller 210 is fixedly connected to an ear hook 220. The inner wall of the ear hook 220 is rotatably connected to a clamping seat 230. The top of the clamping seat 230 is rotatably connected to a pull rope 240. The top of the pull rope 240 is connected to a pull ring 241.

[0026] The specific usage scenario of this embodiment is as follows: by setting the water sampling needle 120 for extracting wastewater, it is convenient to discharge an appropriate amount of wastewater for testing during wastewater inspection, and to facilitate control experiments; by setting the tripod 130 for installing the electric telescopic rod 200, the controller 210 is used to receive electromagnetic signals, so that the electric telescopic rod 200 can be controlled to complete the telescopic control in water through the controller 210; by setting the ear hook 220 for connecting the clamping seat 230, a traction rope 310 of a suitable length is selected, and the two ends of the traction rope 310 are respectively matched and fixedly connected with the bottom of the float 300 and the top of the threaded rod 320, and then the threaded rod 320 is threadedly fixedly connected with the threaded seat 141 at the top of the support seat 140, and then the pull rope 240 is connected to the clamping seat 230.

[0027] Example 3: Figure 4-5 The outer wall of the bottom end of the sampling tube 100 is fixedly installed with a support seat 140, and the top of the support seat 140 is fixedly connected to a threaded seat 141. The bottom of the float 300 is connected with a traction rope 310, and the traction rope 310 is a replaceable structure. The bottom end of the traction rope 310 is fixedly connected to a threaded rod 320, and the outer wall of the bottom end of the threaded rod 320 is threadedly connected with the inner wall of the threaded seat 141.

[0028] The specific usage scenario of this embodiment is: by setting the support seat 140 and the threaded seat 141 for use in conjunction, it is convenient to connect the threaded rod 320, so that the sampling tube 100 can accurately control the diving depth when diving into the wastewater, and by selecting traction ropes 310 of different lengths, or adjusting the length of the traction rope 310, the sampling tube 100 can accurately control the depth of the collected wastewater when sampling wastewater of different depths as needed, thereby improving the accuracy of equipment sampling, and by setting the outer wall of the bottom end of the threaded rod 320 and the inner wall of the threaded seat 141 to cooperate with the threaded connection, it is convenient to improve the installation and disassembly of the traction rope 310, thereby improving work efficiency and convenience of use, and the threaded rod 320 is fixedly connected to the threaded seat 141 at the top of the support seat 140 by threading.

[0029] The working principle of the utility model is as follows: when in use, a person skilled in the art turns on the electric telescopic rod 200 so that the electric telescopic rod 200 controls the piston 250 and the sealing ring 251 to move downward synchronously, so that the piston 250 and the sealing ring 251 move to the bottom of the sampling tube 100, and the air inside the sampling tube 100 is completely discharged. A traction rope 310 of suitable length is selected, and the two ends of the traction rope 310 are respectively matched and fixedly connected with the bottom of the float 300 and the top of the threaded rod 320, and then the threaded rod 320 is threadedly fixedly connected with the threaded seat 141 at the top of the support seat 140, and then the pull rope 240 is connected with the clamping seat 230, and the sampling tube 100 is placed in the wastewater pool to be used. Under the action of gravity, the sampling tube 100 falls into the wastewater. Due to the action of the float 300, when the float 300 is pulled by the bottom of the sampling tube 100, the float 300 floats on the water surface. After the sampling tube 100 sinks to a depth equal to the height of the traction rope 310, it stops sinking. Then, the controller 210 is controlled by the remote control, so that the controller 210 controls the electric telescopic rod 200 to retract, so that the electric telescopic rod 200 pulls the piston 250 and the sealing ring 251 to move toward the tripod 130, thereby forming a negative pressure inside the sampling tube 100. Under the action of the negative pressure, the wastewater is sucked into the sampling tube 100 through the water sampling needle 120. Then, the pull rope 240 is pulled by the handheld pull ring 241. Under the traction of the pull rope 240, the sampling tube 100 is lifted out of the wastewater, thereby completing the sampling of wastewater at different depths.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
