[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 A sewage sample detection device shown in the figure includes a detection machine body 1, a placement slot 2 is reserved in the base of the detection machine body 1, and a detection cup 3 is placed inside the placement slot 2, and the placement slot 2 can also be used to limit the detection cup 3. A cavity 4 is reserved inside the detection machine body 1, and also includes:

[0028] The driving assembly 5 has a motor 51 fixedly connected to the inner wall of the cavity 4, and the output shaft of the motor 51 is drivingly connected to the driving shaft 52, and the outer wall of the driving shaft 52 is fixedly connected to a protrusion 53;

[0029] The linkage mixing component 6, the bottom of the detection cup 3 is rotatably connected to the linkage shaft 61 through a bearing, and the top of the linkage shaft 61 is threadedly connected to the stirring blade 63 through a screw 65, and an interlocking groove 62 is reserved at the bottom of the linkage shaft 61, and the interlocking groove 62 matches the driving shaft 52 and the protrusion 53, so that the driving shaft 52 drives the linkage shaft 61 to rotate synchronously during rotation, and then drives the stirring blade 63 to rotate to mix the sample and the diluent inside the detection cup 3.

[0030] A support ring 8 is fixedly connected to the bottom wall of the placement groove 2 , and the support ring 8 matches the annular groove 9 reserved at the bottom of the detection cup 3 , thereby supporting the bottom of the detection cup 3 .

[0031] The upper end of the driving shaft 52 extends through the interior of the placement groove 2, and the driving shaft 52 is rotatably connected to the through opening via a bearing.

[0032] There are two protrusions 53, and the two protrusions 53 are symmetrically arranged with reference to the central axis of the driving shaft 52 as the symmetry axis, and the protrusion 53 is located inside the placement groove 2. In this way, when the detection cup 3 is placed inside the placement groove 2, the driving shaft 52 and the protrusion 53 match the interlocking groove 62 reserved at the lower end of the linkage shaft 61, the rotation of the driving shaft 52 can drive the rotation of the linkage shaft 61, and then drive the rotation of the stirring blade 63 to mix the sample and the diluent inside the detection cup 3, thereby ensuring the accuracy of the detection result.

[0033] A notch 64 with three open sides is reserved at the top of the linkage shaft 61 , and a stirring blade 63 is inserted and installed inside the notch 64 , so as to facilitate the installation and removal of the stirring blade 63 .

[0034] The stirring blade 63 is arched, and the vertical end walls symmetrically on both sides of the stirring blade 63 are provided with a tip 7, and the tip 7 has a sharp corner made of silicone material, which contacts the inner wall of the detection cup 3, so that when the stirring blade 63 rotates subsequently, the sharp corner can scrape and clean the inner wall of the detection cup 3.

[0035] Working principle: When using a sewage sample detection device, first place the detection cup 3 containing the diluent and the sewage sample inside the placement slot 2, and then match the reserved fitting groove 62 at the lower end of the linkage shaft 61 rotatably connected inside the detection cup 3 with the drive shaft 52 and the protrusion 53 fixedly connected to the outer wall of the drive shaft 52. At this time, the detection cup 3 is placed (after placing the detection cup 3 inside the placement slot 2, the detection cup 3 can be rotated appropriately to facilitate the matching of the lower end of the linkage shaft 61 in the detection cup 3 with the drive shaft 52 and the protrusion 53). The drive shaft 52 connected to the output shaft of the motor 51 is driven by starting the motor 51. At this time, the linkage shaft 61 matched with the drive shaft 52 and located inside the detection cup 3 and the stirring blade 63 threadedly connected inside the linkage shaft 61 rotate to fully mix the sewage sample and the diluent inside the detection cup 3. After the mixing is completed, the detector inside the detection machine body 1 is removed, and the sample that has been relaxed is inserted for data detection.

[0036] When it is necessary to clean the inside of the detection cup 3 later, the tip 7 reserved at the end of the stirring blade 63 can scrape and clean the inner wall of the detection cup 3 when the stirring blade 63 rotates, and the cleaning effect is better. At the same time, the stirring blade 63 can be removed and cleaned separately later. The head of the screw 65 can be twisted to remove it, and the stirring blade 63 can be separated from the notch 64 reserved at the top of the linkage shaft 61, which makes it convenient to remove the stirring blade 63 and is also more convenient to install.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
