Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1 and 2, a weighing and water adding device comprises a centrifugal balance weight pipe 1, wherein the centrifugal balance weight pipe 1 is stably connected with a fixing block 2; install compression spring 3 on the fixed block 2, water pipe head 4 is installed at the top portion of centrifugal counter weight pipe 1, weighing sensor 5 is installed to the bottom portion of centrifugal counter weight pipe 1.

Through the scheme of the utility model, the counter weight water injection device injects water into the centrifugal counter weight tube 1 through the water pipe joint 4 until the weight of the centrifugal counter weight tube 1 is consistent with that of the corresponding blood centrifugal tube.

In addition, a load cell 5 is attached to the bottom end of the centrifugal weight tube 1, and the weight of the centrifugal weight tube 1 can be weighed.

A movable plate 6 is arranged between the water pipe joint 4 and the centrifugal balance weight pipe 1.

The number of the compression springs 3 is two, the bottom ends of the two compression springs 3 are respectively abutted against the fixed block 2 through spring adjusting blocks 7, and the top ends of the two compression springs 3 are respectively connected with linear bearings 8.

The two linear bearings 8 are respectively connected with a top plate 10 through two spring sliding shafts 9.

Through the scheme of the utility model, the spring movable shaft 9 compresses the linear bearing 8, and the linear bearing 8 presses the compression spring 3, so that the movable plate 6 moves along the direction of the centrifugal balance weight pipe 1, and water is injected into the centrifugal balance weight pipe 1 through the water pipe joint 4.

The top plate 10 is abutted against the bottom plate 12 through a vertical plate 11.

With the above-described aspect of the present invention, the vertical plate 11 is used to support the top plate 10 and the bottom plate 12.

A limiting block 13 is arranged between the fixed block 2 and the bottom plate 12.

Through the scheme of the utility model, the limiting block 13 is used for supporting the fixing block 2 and reserving a space for the centrifugal counterweight pipe 1.

And a heightening block 14 is arranged between the centrifugal balance weight pipe 1 and the weighing sensor 5.

For the convenience of understanding the above technical solutions of the present invention, the working principle or the operation mode of the present invention in the practical process will be described in detail as follows:
