When in use, it generally samples from sewage pipes or sewage wells to obtain relevant information about pollutants in the sewage and monitor the water quality.

[0003] According to the sampling method and its use, sewage samplers can be roughly divided into surface sewage samplers, diving sewage samplers, water quality sewage samplers, etc. Among them, the surface sewage sampler is a hand-held sampler, usually suitable for collecting samples of surface water and small water bodies such as ponds. During the use process, generally, the sampling head is directly put into the pond, and then the suction pump is started to make the sampling head sample the sewage. However, in the actual operation process, due to the presence of many suspended particles in the sewage, when extracting, the suspended particles will be simultaneously extracted into the sampler. The presence of suspended particles will interfere with the subsequent test results, resulting in misjudgment. Therefore, there is an urgent need for a sewage sampler for sewage detection to solve the above problems. Content of the Utility Model

[0025] To make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present invention in conjunction with the attached drawings of the specification.

[0026] Embodiment 1

[0027] Refer to Figures 1-3, which is the first embodiment of the present utility model, provides a sewage sampler for sewage detection. This sewage sampler for sewage detection includes a main body 1, a sampling pipe 2 installed on one side of the main body 1, a sampling head 21 installed at one end of the sampling pipe 2, and a water outlet pipe 5 installed on the top of the main body 1. A water pump for sampling is installed inside the main body 1, and its connection relationship with the water outlet pipe 5 and the sampling pipe 2 is prior art and will not be elaborated here. A handle for easy grasping is installed on the surface of the main body 1. A filtering member 3 is installed on one side of the sampling head 21, and an auxiliary member 4 is installed on the surface of the sampling pipe 2. The auxiliary member 4 is located above the filtering member 3;

[0028] The filtering member 3 includes a filtering pipe 31 installed on one side of the sampling head 21. An activated carbon filter screen 32 is movably sleeved inside the filtering pipe 31. Both the filtering pipe 31 and the activated carbon filter screen 32 are inclined. A blocking block 33 is installed inside the sampling head 21. Both the filtering pipe 31 and the activated carbon filter screen 32 extend into the inside of the sampling head 21 and extend to the bottom of the blocking block 33 and are in contact with it. The blocking block 33 and the sampling head 21 are of an integrally formed structure. As Figure 2 shown, when observed in a planar manner, water flows in through the right side, i.e., the other side of the label 2, enters through the filtering pipe 31 and the activated carbon filter screen 32 into the inside of the activated carbon filter screen 32, and enters into the inside of the label 2 through the groove 34. At the same time, the sampling head 21 and the filtering pipe 31 form a y shape. At the same time, the setting of the blocking block 33 can facilitate the flow of water, so that the water can better enter into the inside of the activated carbon filter screen 32, and can block the excess cavity inside the sampling head 21. In addition, the activated carbon filter screen 32 can filter suspended solid particles and heavy metal impurities to prevent these impurities from interfering with subsequent detection operations.

[0029] A groove 34 is opened on one side of the filtering pipe 31 and inside the sampling head 21. The sampling head 21 communicates with the filtering pipe 31 through the groove 34, which can facilitate the flow of the filtered sewage.

[0030] The bottom of the filtering pipe 31 is movably connected with a rotary cover 35. An external thread 36 is fixedly connected to the outer surface of the rotary cover 35. A threaded groove 37 is opened inside the filtering pipe 31. The external thread 36 is located inside the threaded groove 37 and is threadedly connected with it. The diameter of the rotary cover 35 located inside the filtering pipe 31 is the same as the diameter of the activated carbon filter screen 32, which can facilitate its positioning and prevent it from shifting inside the filtering pipe 31.

[0031] During use, the sampling pipe 2 is placed into the pond, and the floating ball 46 is located on the surface of the pond water level, which can keep the sampling head 21 stable. Then, the water pump inside the main body 1 is started to enable the sampling head 21 to extract sewage. During this process, the sewage will pass through Figure 2One end of the unlabeled sampling head 21 in it flows towards the inside of the activated carbon filter screen 32. At the same time, the sewage, suspended solid particles, and heavy metals are jointly pumped into the inside of the activated carbon filter screen 32. The suspended solid particles and heavy metals will be intercepted by the activated carbon filter screen 32. The filtered sewage will move towards the inside of the sampling tube 2 through the groove 34. In this way, the suspended solid particles and heavy metals in the sewage can be filtered to avoid interfering with the subsequent test results due to these two factors;

[0032] When replacing the activated carbon filter screen 32, rotate the rotary cover 35 in the reverse direction so that it rotates along the thread groove 37 inside the filter tube 31 through the external thread 36 on its outer surface, and slowly separates from it until the two are completely separated. Then directly take out and replace the activated carbon filter screen 32. In this way, the purpose of quickly replacing the activated carbon filter screen 32 can be achieved.

[0033] Embodiment 2

[0034] Refer to Figures 1-6 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is:

[0035] The auxiliary part 4 includes a mounting ring 41 fixed on the outer surface of the sampling tube 2. A connecting ring 43 is movably sleeved on the outer surface of the mounting ring 41. A suspension ball 46 is installed on the outside of the connecting ring 43. The suspension ball 46 is arranged in an oblate shape, which can reduce its buoyancy to ensure the accuracy and stability of the sampling head 21. At the same time, the mounting ring 41 and the connecting ring 43 are respectively fixedly connected to the sampling tube 2 and the suspension ball 46.

[0036] A first connecting groove 42 and a second connecting groove 44 are respectively formed inside the mounting ring 41 and the connecting ring 43;

[0037] At the bottom of the first connecting groove 42 and the second connecting groove 44 and inside the mounting ring 41 and the connecting ring 43, clamping grooves 45 are formed, which can facilitate the connection of the sampling tube 2 and the suspension ball 46.

[0038] A C-shaped plate 47 is movably connected inside the first connecting groove 42 and the second connecting groove 44. The C-shaped plate 47 is hollow inside, which can facilitate the connection with the mounting ring 41 and the connecting ring 43. Its two ends are located inside the first connecting groove 42 and the second connecting groove 44;

[0039] A clamping block 48 is fixedly connected to the inner side of the C-shaped plate 47. The clamping block 48 is located inside the clamping groove 45 and is clamped with it. The bottom of the clamping block 48 is provided with an inclined surface, which can facilitate the connection with the clamping groove 45. In this way, the mounting ring 41 and the connecting ring 43 can be connected.

[0040] A handle 49 is fixedly connected to the top of the C-shaped plate 47. The handle 49 is arranged in a conical shape, which can facilitate the insertion and extraction operation of the operator.

[0041] When collecting water samples with a traditional sewage sampler, it is usually necessary to adjust the lying angle of the sampler to ensure that the bottom of the sampler is in contact with the water surface, which may affect the sensitivity of the sampler. By setting a floating ball 46 on the top of the sampling head 21, the angle of the sampling head 21 can be automatically adjusted, thereby improving the sensitivity of the sampler and ensuring the accuracy of sampling;

[0042] At the same time, compared with the traditional round floating ball 46, the floating ball 46 with an oval shape has a smaller buoyancy, which can prevent the sampling head 21 from shaking randomly when the floating ball 46 is slightly affected by the wind direction, ensure the accuracy and stability of the sampling head 21, and also reduce the impact of the sampler on water pollution.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
