[0026] 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.

[0027] In the embodiment, Figure 1-4 A urine collection device for cultivating experimental mice is provided. The utility model comprises a base 1, a support frame 2 is arranged on the top of the base 1, a cultivation frame 3 is fixedly connected inside the support frame 2, a plurality of leakage holes are provided on the inner bottom wall of the cultivation frame 3, a connecting frame 4 is fixedly connected to the bottom of the cultivation frame 3, a first connecting plate 5 is fixedly connected to the left and right sides of the connecting frame 4, a filter frame 6 is arranged on the bottom of the connecting frame 4, a second connecting plate 7 located below the first connecting plate 5 is fixedly connected to the left and right sides of the filter frame 6, a filter plate 8 is arranged inside the filter frame 6, a plurality of filter holes are provided inside the filter plate 8, and a first receiving box 9 located below the filter frame 6 is arranged on the top of the base 1.

[0028] The interior of the connection frame 4 and the interior of the filter frame 6 are both arranged to be inclined inwards, and a switch valve 10 is arranged inside the filter frame 6 .

[0029] In this embodiment, during actual use, the excrement of the experimental mice will fall from the connecting frame 4 into the filter frame 6 through the inclined slope, and the excrement can be discharged by opening the switch valve 10.

[0030] A clearance groove is provided inside the filter frame 6 , and the filter plate 8 passes through the clearance groove and extends to the outside of the filter frame 6 . A second receiving box 11 located below the filter plate 8 is provided on the top of the base 1 .

[0031] In this embodiment, during actual use, feces in the excrement will fall onto the filter plate 8 and roll down along the filter plate 8 into the second receiving box 11 .

[0032] The outer diameter of the bottom surface of the connection frame 4 is smaller than the inner diameter of the top surface of the filter frame 6 , and the installation height of the top surface of the filter frame 6 is higher than the installation height of the bottom surface of the connection frame 4 .

[0033] In this embodiment, during actual use, when excrement passes through the connecting frame 4 , it will not fall into the gap between the connecting frame 4 and the filtering frame 6 .

[0034] Among them, two limiting grooves are opened inside the two first connecting plates 5, and two clamping blocks 12 are fixedly connected to the top of the two second connecting plates 7 and are respectively slidably connected to the four limiting grooves. Transverse limiting holes are opened inside the four clamping blocks 12, and the two first connecting plates 5 are each provided with a limiting rod 13 that is respectively slidably connected to the inside of the four transverse limiting holes.

[0035] In this embodiment, during actual use, the limiting groove in the first connecting plate 5 is aligned, and the second connecting plate 7 is moved to a suitable position by docking the block 12 with the limiting groove, and then the connecting frame 4 and the filter frame 6 can be connected by connecting the limiting rod 13 with the transverse limiting hole.

[0037] In this embodiment, during actual use, the rope 15 is pulled, and the filter plate 8 rotates in the filter frame 6. When the filter plate 8 falls, it collides with the clearance groove of the filter frame 6 and generates vibration, so that the feces remaining on the filter plate 8 is shaken into the second receiving box 11.

[0038] Working principle:

[0039] The experimental mice are placed in the cultivation frame 3, and food and water are provided for the experimental mice. When the experimental mice excrete crumbs, a small amount of feces will be blocked and filtered for the first time by the leakage holes, and the excrement will fall into the filter frame 6 through the inclined connecting frame 4. The feces will be blocked for the second time when they fall on the filter plate 8, and will roll along the filter plate 8 to the second receiving box 11. The urine will fall downward along the filter holes on the filter plate 8, and will finally be blocked in the filter frame 6 by the switch valve 10. When the switch valve 10 is opened, the urine can be collected through the first receiving box 9.
