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.

[0020] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0021] An experimental liquid collection and measurement device includes a base 1, the surface of the base 1 is slidably connected to a support frame, the top of the support frame is connected to a liquid storage chamber 8, one end of the liquid storage chamber 8 is connected to a telescopic tube 12 through a connecting tube 10, the other end of the liquid storage chamber 8 is respectively connected to a vacuum chamber 15 and a liquid outlet pipe 19, the other end of the telescopic tube 12 is connected to a liquid collecting pipe 13, the other end of the liquid collecting pipe 13 is provided with a connector 14, the other end of the liquid outlet pipe 19 is connected to a drain pipe 22 through a faucet 20, the other end of the drain pipe 22 is provided with a collecting container 23, and the bottom of the collecting container 23 is provided with a collecting table 24.

[0022] In the present invention, the support frame includes a chute provided on the surface of the base 1, with a lifting seat 3 slidably connected to the inside of the chute. A lifting rod 4 is provided on the top of the lifting seat 3. A connecting rod 6 is connected to the top of the lifting rod 4 through a locking mechanism 5. A fixing frame 7 is provided at the other end of the connecting rod 6. The fixing frame 7 is fixedly connected to the outside of the liquid storage chamber 8. The two ends of the chute are respectively fixedly connected to the surface of the base 1. A limit block 2 is fixedly connected.

[0023] In the present invention, a plurality of liquid level scales 9 are provided on the surface of the liquid storage chamber 8 , and the liquid level scales 9 are provided perpendicularly to each other on the surface of the liquid storage chamber 8 .

[0024] In the present invention, valves 11 are provided at the connection between the liquid collecting pipe 13 and the telescopic pipe 12 and at the connection between the liquid storage chamber 8 and the liquid outlet pipe 19 .

[0025] In the present invention, a piston plate 16 is provided on one side of the vacuum chamber 15 close to the liquid storage chamber 8 , a piston rod 17 is connected to the center of the other end of the piston plate 16 , and the other end of the piston rod 17 passes through the vacuum chamber 15 and is connected to a handle 18 .

[0026] In the present invention, the liquid outlet pipe 19 and the faucet 20 are rotatably connected, and a switch 21 is further provided on the outside of the faucet 20 .

[0027] In the present invention, a plurality of springs 25 are evenly arranged inside the collecting platform 24 , and a placement plate is connected to the top of the spring 25 , and a groove for placing the collecting container 23 is reserved on the surface of the placement plate.

[0028] Example 1: When using a liquid collection device to be tested that is positioned lower, first place the base 1 next to the liquid collection device to be tested, connect the telescopic tube 12 to the side of the liquid collection device to be tested through the connector 14 at the end of the liquid collection tube 13, then open the valve at the connection between the liquid collection tube 13 and the telescopic tube 12, close the valve 11 set at the connection between the liquid storage chamber 8 and the liquid outlet pipe 19, and then pull the handle 18 to drive the piston rod 17, and then drive the piston plate 16 to move to the side close to the handle 18, and then the inside of the vacuum chamber 15 collects the liquid to be tested inside the telescopic tube 12, the connecting tube 10 and the liquid collection tube 13 under the action of negative pressure, and collects it into the liquid storage chamber 8, and the volume of the liquid to be tested inside the liquid storage chamber 8 can be observed through the liquid level scale 9 on the surface of the liquid storage chamber 8. After all the liquid to be tested has entered the liquid storage chamber 8, the valve at the connection between the collecting pipe 13 and the telescopic tube 12 is closed, the valve 11 provided at the connection between the liquid storage chamber 8 and the liquid outlet pipe 19 is opened, and the switch 21 of the faucet 20 is turned on. The liquid to be tested can then flow through the liquid outlet pipe 19, the faucet 20, and the drain pipe 22 into the collection container 23. As the weight inside the collection container 23 increases, the spring 25 inside the collection table 24 is compressed, ensuring that the collection container 23 can be stably placed in the groove on the surface of the placement plate. At the same time, before use, the height of the fixing frame 7 can be adjusted by adjusting the lifting seat 3 in conjunction with the lifting rod 4, the locking mechanism 5, and the connecting rod 6, thereby adjusting the height of the liquid storage chamber 8, and then adjusting the height of the entire device, to ensure that the connector 14 can be accurately connected to the liquid outlet of the liquid collection device to be tested.

[0029] Example 2: This example differs from Example 1 in that, when used with a higher-positioned liquid collection device and a liquid outlet located at the bottom of the device, the locking mechanism 5 can be adjusted to maintain the connecting rod 6 and the lifting rod 4 in a vertical position, ensuring that the liquid storage chamber 8 fixedly connected to the fixing frame 7 rotates, allowing the connector 14 to connect with the liquid outlet at the bottom of the liquid collection device. Simultaneously, the entire device can be moved in conjunction with the slide groove on the surface of the base 1 to ensure that the outlet of the drain pipe 22 is always at the top of the collection container 23. The limit block 2 can limit the lifting seat 3 to prevent it from sliding off the surface of the base 1.

[0030] Example 3: Compared with Examples 1-2, this example differs in that: regardless of whether the liquid collection device to be tested is located at a lower or higher position, a timer can be set on the surface of the liquid storage chamber 8 when in use. When the liquid is collected in the liquid storage chamber 8, the timer is used to synchronously count the time, so that the liquid flow rate is calculated based on the time and the liquid volume data inside the liquid storage chamber 8, thereby completing the measurement of the liquid flow rate.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
