[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a reverse osmosis membrane sampling and detection device, including a sampling box body 1, a rotating shaft ring 2 is rotatably connected to the top of the inner wall of the rear end of the sampling box body 1, and a shaking component is fixedly connected to the inner wall of the rotating shaft ring 2. The shaking component includes a handle 3. The rotating shaft ring 2 here is to protect the handle 3 and the sampling box body 1 to prevent the device from being worn due to long-term friction between the two. The outer front end of the handle 3 is fixedly connected to the inner wall of the rotating shaft ring 2.

[0025] Reference Figure 1-Figure 3The outer rear end of the handle 3 is rotatably connected to a friction ring 4, and the friction ring 4 here is used to increase the friction with the user's palm to prevent slipping. The front end of the shaking component is fixedly connected to a rotating shaft 1 5, and the rear end of the rotating shaft 1 5 is rotatably connected to the rear end of the inner wall of the sampling box body 1, and the other end of the rotating shaft 1 5 is rotatably connected to a rotating shaft 2 6. When the rotating shaft 1 5 here is rotated, it will drive the rotating shaft 2 6 to rotate together, and the other end of the rotating shaft 2 6 is rotatably connected to a supporting base plate 7.

[0026] Reference Figure 1-Figure 3 The front and rear ends of the supporting base plate 7 are slidably connected to the inner wall of the sampling box body 1. The rotating shaft 6 here will drive the supporting base plate 7 to move up and down when it rotates. Grooves 8 are provided on the left and right inner walls of the sampling box body 1. Slide blocks 9 are slidably connected to the inner walls of the grooves 8. The adjacent sides of the two slide blocks 9 are fixedly connected to the left and right sides of the supporting base plate 7 respectively. The slide blocks 9 here ensure that the supporting base plate 7 maintains linear motion when moving up and down to prevent deviation.

[0027] Reference Figure 2 and Figure 4 The bottom end of the slider 9 is fixedly connected with a plurality of bottom columns 10, and the bottom inner wall of the sampling box body 1 is threadedly connected with a plurality of suction components, the suction components here are used to absorb water samples from the reverse osmosis membrane for detection, and the suction components include a container 13, the outer thread of the container 13 is connected to the bottom inner wall of the sampling box body 1, and the sampling box body 1 here provides a stable support for the container 13, and a slide groove 15 is opened inside the container 13, and a tensile column 12 is slidably connected to the top of the inner wall of the slide groove 15.

[0028] Reference Figure 2 and Figure 4 The slide groove 15 here provides a stable sliding space for the stretching column 12. The top of the stretching column 12 is fixedly connected with a suction cup 11, and the top of the suction cup 11 contacts the bottom end of the bottom column 10. The suction cup 11 here will be tightly adsorbed with the bottom column 10 after contacting it. The outside of the container 13 is fixedly connected with a sealing ring 14. The sealing ring 14 here is to ensure the sealing of this device, and secondly, to ensure that reverse osmosis membrane water samples of different depths can be sampled at one time during multiple sampling. The positions of the sealing rings 14 on the multiple suction components here are gradually deepened, so the container 13 can be controlled to collect water samples of different depths.

[0029] Reference Figure 2 and Figure 4The top of the sealing ring 14 contacts the bottom of the sampling box body 1, the bottom of the stretching column 12 is fixedly connected with a rubber pad 16, the bottom of the rubber pad 16 contacts the top of the suction tube 17, the outside of the rubber pad 16 is slidably connected to the inner wall of the slide 15, the rubber pad 16 here is used to cooperate with the slide 15 to collect and absorb water samples, the bottom of the container 13 is fixedly connected with the suction tube 17, and the top of the sampling box body 1 is fixedly connected with a handrail 18, and the handrail 18 here is used for the staff to control the device steadily, so as to facilitate the subsequent collection of water samples from the reverse osmosis membrane.

[0030] Working principle: When using this device, the staff can first hold the handrail 18, and then install the container 13 on the bottom end of the sampling box body 1 according to the number of reverse osmosis membrane water samples to be collected so that the bottom end of the bottom column 10 contacts the top of the suction cup 11, and then put the sampling box body 1 into the water sample. At this time, the handle 3 can be turned. The friction ring 4 here plays a role in increasing friction and preventing sliding. Then the handle 3 will drive the rotating shaft 1 5 and the rotating shaft 2 6 to rotate. The rotating shaft ring 2 here plays a supporting role, while preventing wear between the handle 3 and the sampling box body 1, thereby increasing the service life of this device.

[0031] Then, when the rotating shaft 2 6 rotates, it will drive the supporting bottom plate 7 and the sliding block 9 to slide up and down in the groove of the groove 8. At this time, the supporting bottom plate 7 will drive the multiple bottom columns 10 at its bottom end to move up and down, thereby driving the suction cup 11, the stretching column 12 and the rubber pad 16 to slide inside the container 13, so that the water sample of the reverse osmosis membrane is sucked into the interior of the container 13 by the suction tube 17. The sealing ring 14 here plays a role of limiting and preventing the penetration of the water sample. After collecting multiple reverse osmosis membrane water samples at different depths, the staff can perform detection operations on them.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
