[0002] In some experimental research processes, it is necessary to obtain a predetermined reaction liquid or catalyst. At this time, a sampling and metering detection device is needed to obtain the predetermined liquid volume.

[0003] After searching, China's authorized publication number CN216081654U discloses a metering and detection device for liquid measurement, including a metering box, a bottom plate fixedly connected to the bottom of the metering box, a base fixedly connected to a corner of the bottom plate, a guide rod fixedly connected to the side of the bottom plate close to the metering box, and a limit plate fixedly connected to the end of the guide rod away from the bottom plate. The advantages of the utility model are: through the coordination between the metering box, the guide rod, the measuring ruler, the movable plate, the movable frame, the reading mark, the locking rod, the pull ring, the locking block and the spring, workers are prevented from forgetting to read the reading when measuring the liquid, thereby reducing the workers' work intensity and workload; through the coordination between the support frame fixedly connected to one side of the metering box and the filter frame and the filter screen, the filter frame is rotated, and the filter screen is driven by the filter frame to rotate to the top of the metering box, so that filtering can be carried out, thereby preventing impurities from entering the interior of the metering box.

[0004] An existing metering and detection device for liquid measurement can only measure the liquid injected into the metering box when in use. When a certain amount of liquid needs to be injected, it is difficult to control and the operator needs to slowly inject the liquid. In addition, there is a possibility of overinjection during this process. When too much is injected, the liquid needs to be poured out, which is cumbersome and inconvenient to use. Utility Model Content

[0005] The purpose of the present utility model is to provide a metering and detection device for liquid measurement, so as to solve the problem in the above background technology that an existing metering and detection device for liquid measurement can only measure the liquid injected into the metering box when in use. When a certain amount of liquid needs to be injected, it is difficult to control and the operator needs to slowly inject the liquid. In addition, there is a situation where too much liquid is injected during this process. When too much liquid is injected, the liquid needs to be poured out, which is cumbersome to operate and inconvenient to use.

[0006] In order to solve the above technical problems, the present invention provides a measuring and detecting device for liquid measurement, comprising:

[0007] a support assembly, the support assembly comprising a cover plate;

[0008] A quantitative component includes a first through hole opened at the central position of the upper end of the cover plate, a water injection pipe connected to the central position of the cover plate, second through holes opened at both sides of the upper end of the cover plate, a guide rod connected to the internal positions on both sides of the cover plate, a floating plate connected to the bottom end of the guide rod and a sealing plug connected to the central position of the upper end of the floating plate.

[0009] Furthermore, the support assembly also includes a barrel body and a water outlet pipe connected to the bottom end of the barrel body, and a cover plate is connected to the top end of the barrel body.

[0010] Furthermore, the inner surface of the first through hole and the outer surface of the water injection pipe are provided with corresponding thread structures, and the outer surface of the water injection pipe has scale lines.

[0011] Furthermore, the guide rod extends outward through the second through hole, and a water filtering hole is provided at the upper end of the floating plate.

[0012] Furthermore, the sealing plug is located below the water injection pipe, and the outer side of the floating plate is in contact with the inner wall of the barrel.

[0013] Furthermore, it also includes a cleaning component, which includes a hollow disc connected to the bottom end of the cover plate, an air outlet opened at the bottom end of the hollow disc, a heating rod connected to the inside of the hollow disc, an air intake pipe connected to one side of the upper end of the hollow disc, and an air pump connected to the outer end of the air intake pipe.

[0014] Furthermore, the air inlet pipe extends outward through one side of the upper end of the cover plate, and the air pump is fixedly connected to one side of the upper end of the air pump.

[0015] Furthermore, the hollow disc is located above the floating plate, and the heating rods and the air outlet holes are staggered.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a quantitative component, when a certain amount of liquid needs to be injected into the interior of the box, the water injection pipe is rotated according to the scale line on the outer surface of the water injection pipe, so that the water injection pipe moves a corresponding distance along the thread structure, and then the liquid is injected into the interior of the box through the water injection pipe. The liquid flows to the upper end of the floating plate and flows downward through the water filtering hole. The rising liquid drives the floating plate to move upward. When the water level reaches the required position, the floating plate drives the sealing plug to move upward and enter the interior of the water injection pipe, thereby blocking the water injection pipe, so that the liquid inside can be quantitatively measured. The operation is simple and convenient to use.

[0017] At the same time, by setting up a cleaning component, when the next metering test is needed after use, the heating rod is started to generate heat and enter the barrel through the air outlet, and then the air pump is started to generate wind through the air inlet pipe and the hollow disc to enter the barrel, so that the liquid attached to the inner wall of the barrel flows out and the drying of the inside of the barrel is accelerated to prevent the liquid from remaining inside the barrel and affecting the next metering test.

[0027] A support assembly, the support assembly includes a cover plate 12;

[0028] The dosing assembly includes a first through hole 21 provided at the center of the upper end of the cover plate 12, a water injection pipe 22 connected to the center of the cover plate 12, second through holes 23 provided at both sides of the upper end of the cover plate 12, guide rods 24 connected to the inner positions of both sides of the cover plate 12, a floating plate 25 connected to the bottom end of the guide rods 24, and a sealing plug 26 connected to the center of the upper end of the floating plate 25;

[0029] The first through hole 21 is used to accommodate a water injection pipe 22, which is used to block the upper end of the floating plate 25 and inject water into the barrel body 11. The second through hole 23 is used to accommodate a guide rod 24, which is used to support the floating plate 25. The sealing plug 26 is used to seal the lower end of the water injection pipe 22.

[0030] The support assembly further includes a barrel body 11 and a water outlet pipe 13 connected to the bottom end of the barrel body 11, and a cover plate 12 connected to the top end of the barrel body 11;

[0032] The inner surface of the first through hole 21 and the outer surface of the water injection pipe 22 are provided with corresponding thread structures, and the outer surface of the water injection pipe 22 has scale lines;

[0033] The water injection pipe 22 can move up and down inside the first through hole 21 through a threaded structure and is fixed inside the first through hole 21;

[0034] The guide rod 24 extends outward through the second through hole 23, and a water filter hole is formed at the upper end of the floating plate 25;

[0035] When the floating plate 25 moves, it is limited by the guide rod 24 and can only move in the vertical direction;

[0036] The sealing plug 26 is located below the water injection pipe 22, and the outer side of the floating plate 25 is in contact with the inner wall of the barrel body 11;

[0037] When the floating plate 25 moves upward under the buoyancy of the liquid, it can drive the sealing plug 26 to move upward;

[0038] Working principle: When quantitative measurement is required, a rotational force is applied to the water injection pipe 22 through the scale lines on the outer surface of the water injection pipe 22, so that the water injection pipe 22 rotates and moves under the drive of the threaded structure. When the water injection pipe 22 moves to the required position, the liquid is injected downward from the upper end of the water injection pipe 22. The liquid enters the upper end of the float plate 25 through the water injection pipe 22 and flows downward through the filter water hole. When the liquid flows to the lower end of the float plate 25, the float plate 25 moves upward under the buoyancy of the liquid. The upward movement of the float plate 25 drives the sealing plug 26 to move upward. When the float plate 25 moves to the upper end and contacts the bottom end of the water injection pipe 22, the sealing plug 26 enters the inside of the water injection pipe 22 to block the liquid, and the required amount of liquid can be obtained.
