DETAILED DESCRIPTION

[0019] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit 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.

[0020] Example 1

[0021] See also Figures 1-4The utility model provides a technical solution: a sampling device for collecting water quality data of pipeline direct drinking water equipment, the sampling device for collecting water quality data of pipeline direct drinking water equipment includes: a direct drinking water pipeline 1, the upper end of the outer side of the direct drinking water pipeline 1 is connected with a water outlet pipe 2, the upper end surface of the water outlet pipe 2 is provided with a sealing groove 8, the sealing groove 8, and the sampling device is correspondingly and sealedly inserted in the sealing groove 8; the sampling device includes a collecting pipe 4, the lower end of the collecting pipe 4 is fixedly connected with a sealing sleeve 5, and the sealing sleeve 5 is correspondingly and sealedly inserted in the sealing groove 8.

[0022] When sampling is required, the sealing sleeve 5 is first inserted into the sealing groove 8. Since the sealing sleeve 5 and the sealing groove 8 are sealed to each other, it is ensured that no water resources will flow out and cause waste during sampling.

[0023] Example 2

[0024] On the basis of embodiment 1, the lower end surface of the outlet pipe 2 is fixedly connected to a retractable rod 10, and the lower end of the retractable rod 10 is fixedly connected to a sealing plug 9, which is correspondingly and sealingly plugged into the outlet pipe 2.

[0025] The retracting rod 10 is always in a retracted state. When no external force acts on the sealing plug 9, the retracting rod 10 can seal the sealing plug in the water outlet pipe 2 to achieve sealing.

[0026] Example 3

[0027] On the basis of Example 2, a piston spring 13 is fixedly connected to the upper end face of the inner side of the collecting tube 4, and a collecting piston 11 is fixedly connected to the lower end of the piston spring 13. The sealing sleeve of the collecting piston 11 is arranged in the collecting tube 4, and a piston rod 7 is provided in the middle sealing sleeve of the collecting piston 11. The upper end of the piston rod 7 is fixedly connected to the adjusting rod 3. The collecting tube 4 is provided with a sealing port 14 on the inner side of the sealing sleeve 5, and a pressing piston 6 is fixedly connected to the lower end of the piston rod 7. The pressing piston 6 is correspondingly sealed and inserted in the sealing port 14. A plurality of air pressure holes 12 are opened on the upper end face of the collecting tube 4.

[0028] When the sealing sleeve 5 is inserted in the sealing groove 8, the adjusting rod 3 is pushed, so that the pressing piston 6 is disengaged from the sealing port 14 under the action of the piston rod 7, and continues to descend, pressing the sealing plug 9 to disengage the seal and insert it into the water outlet pipe 2. At this time, the direct drinking water in the pipe enters the collecting pipe 4 from the water outlet pipe 2 under the action of the pressure in the pipe. Due to the collection piston 11, the pressure balance in the collecting pipe 4 can be achieved, and no water overflows. The air pressure hole 12 achieves air pressure balance between the collecting piston 11 and the collecting pipe 4. When the collection is completed, the adjusting rod 3 is pulled back to achieve the sealing insertion of the pressing piston 6 in the sealing port 14, completing the collection process.

[0029] In actual use, when sampling is required, the sealing sleeve 5 is first inserted into the sealing groove 8. Since the sealing sleeve 5 and the sealing groove 8 are sealed to each other, it is ensured that no water resources will flow out during sampling, causing waste. When the sealing sleeve 5 is inserted into the sealing groove 8, the adjusting rod 3 is pushed, so that the pressing piston 6 is separated from the sealing port 14 under the action of the piston rod 7, and continues to descend, pressing the sealing plug 9 to separate it from the seal and insert it into the water outlet pipe 2. At this time, the drinking water in the pipe flows out from the outlet under the action of the pressure in the pipe. The water pipe 2 enters the collecting pipe 4. Due to the collecting piston 11, the pressure balance in the collecting pipe 4 can be achieved, and there will be no water overflow. The air pressure hole 12 realizes the air pressure balance between the collecting piston 11 and the collecting pipe 4. When the collection is completed, the adjusting rod 3 is pulled back to realize the sealing insertion of the pressing piston 6 in the sealing port 14 to complete the collection process. The retracting rod 10 is always in the retracted state. When there is no external force acting on the sealing plug 9, the retracting rod 10 can seal the sealing plug in the water outlet pipe 2 to achieve sealing.

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