[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0026] See also Figure 1-5 The utility model provides a technical solution: a device for collecting evidence on-site for environmental law enforcement, comprising:

[0027] A sewage pipe 1, wherein the sewage pipe 1 is used to discharge sewage;

[0028] A collecting bucket 2, wherein the collecting bucket 2 is used to store sewage;

[0029] A mounting plate 3 is provided with a plurality of mounting grooves 31, wherein the mounting grooves 31 are used to place the collection bucket 2, and the mounting plate 3 is arranged at the lower side of the water outlet of the sewage pipe 1;

[0030] A driving assembly 4, wherein the driving assembly 4 is used to drive the mounting plate 3 to rotate;

[0031] The card and component 5 can stop the rotation of the mounting disc 3. When the sewage is discharged through the sewage pipe 1, the sewage will flow into the collection bucket 2. When the collection bucket 2 is full, the driving component 4 drives the mounting disc 3 to rotate. At the same time, the card and component 5 no longer clamps the mounting disc 3, and then switches to the next collection bucket 2. In this way, each time the sewage is discharged, the sewage discharged this time can be collected, reducing the workload of the evidence collector.

[0032] The driving assembly 4 also includes a driving rod 41, which passes through the sewage pipe 1. The driving rod 41 is located in the sewage pipe 1 and is fixedly connected to a bevel gear 42 at the end thereof. A spiral blade 43 is provided in the sewage pipe 1, and one end of the spiral blade 43 is fixedly connected to a driving rod 2 44. One end of the driving rod 2 44 is fixedly connected to a bevel gear 2 45. The bevel gear 1 42 is meshed with the bevel gear 2 45. The bottom of the driving rod 41 extends into the mounting plate 3. When sewage passes through the sewage pipe 1, the water flow drives the spiral blade 43 to rotate. The spiral blade 43 drives the bevel gear 42 meshed with it to rotate through the bevel gear 2 45 at the end of the driving rod 2 44, and the driving rod 41 fixedly connected to the bevel gear 42 rotates accordingly.

[0033] The inner wall of the sewage pipe 1 is fixedly connected with a connecting rod 46 , and the second driving rod 44 is rotatably connected to the connecting rod 46 . The connecting rod 46 is fixedly arranged on the inner wall of the sewage pipe 1 so that the second driving rod 44 can rotate stably in the sewage pipe 1 .

[0034] A fixed plate 32 is provided on one side of the mounting plate 3, and the fixed plate 32 is fixedly connected to the outer wall of the sewage pipe 1. A slot 33 is provided on one side of the fixed plate 32, and the slot 33 allows the collecting bucket 2 to pass through. The fixed plate 32 is located in the mounting slot 31 and is provided with a spring 34. One end of the spring 34 is fixedly connected to the fixed plate 32, and the other end of the spring 34 is fixedly connected to the bottom of the collecting bucket 2. When the mounting plate 3 rotates, the collecting bucket 2 rotates to the slot 33, the elastic potential energy of the spring 34 is converted into kinetic energy to lift the collecting bucket 2. At this time, the collecting bucket 2 cannot move because it is stuck in the fixed plate 32, and the mounting plate 3 cannot move because the collecting bucket 2 is stuck. When the sewage fills the collecting bucket 2, the mass of the collecting bucket 2 increases after being filled with sewage, and the collecting bucket 2 moves downward to compress the spring 34 again, and its top is lower than the surface of the fixed plate 32, waiting for the next collecting bucket 2 to be lifted.

[0035] The fixed plate 32 is provided with a pulley 35 at the slot 33. Two groups of pulleys 35 are symmetrically arranged about the slot 33. The pulleys 35 are rotatably connected to the fixed plate 32. By arranging pulleys 35 on both sides of the slot of the fixed plate 32, the friction force on the collection barrel 2 when moving in the vertical direction can be reduced, making its up and down movement smoother.

[0036] The fixing plate 32 has a rounded corner at the lower edge of the slot 33. By having a rounded corner at the bottom of the slot, the collecting bucket 2 can move upward along the rounded edge when it moves to the slot of the fixing plate 32 to avoid getting stuck.

[0037] The driving rod 41 is located on the inner and outer walls of the mounting plate 3 and is connected to a vortex spring 61. One end of the vortex spring 61 is fixedly connected to the driving rod 41, and the other end of the vortex spring 61 is fixedly connected to the inner wall of the mounting plate 3. A ratchet is provided between the driving rod 41 and the mounting plate 3. During the rotation of the driving rod 41, the vortex spring 61 is compressed due to the rotation of the driving rod 41. At this time, the vortex spring 61 generates elastic potential energy. When the collecting bucket 2 is full of collection and drops, the mounting plate 3 is not constrained, and the mounting plate 3 rotates to the next collecting bucket 2 and lifts up.

[0038] The fixing plate 321 is slidably connected to the fixing disc 32 . When evidence collection is required, the collecting barrel 2 can be taken out by simply removing the fixing plate 321 .
