[0016] The negative pressure is mainly generated by a small water pump at the bottom of the floating block, so that the poured plant mixed liquid continuously passes through the funnel-shaped bottom sleeve. During the continuous passage of the liquid, the mixed liquid in the liquid is blocked in the funnel-shaped bottom sleeve by the filter body and gradually accumulates. When the liquid is completely poured into the measuring cylinder, the funnel-shaped bottom sleeve is docked to the bottom of the floating block, and the accumulated lumps are confined in the inner space. Then the external discharge mechanism is docked with the inner space of the floating block to suck out the lumps and avoid affecting the liquid level measurement.

DETAILED DESCRIPTION

[0023] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 4As shown, in an embodiment of the present invention, a measuring float 100 comprises: a floating block 10, a measuring tube 20 and a laser rangefinder 30. The floating block 10 is arranged in the measuring tube 20. The laser rangefinder 30 is installed in pairs on both sides of the floating block 10, and the laser transmitting and receiving end of the laser rangefinder 30 is vertically upward. At the same time, the laser rangefinder 30 is equipped with a liquid level height calculation device. When the plant liquid whose liquid level height needs to be measured is poured into the measuring tube 20, the floating block 10 floats and rises under the action of the buoyancy of the liquid. When it rises and stays at the corresponding height, the laser rangefinder 30 detects the distance between the floating block 10 and the tube cover 21. Since the depth of the measuring tube 20 itself is fixed, the liquid level position of the plant liquid poured into the measuring tube 20 can be directly calculated by the liquid level calculation device by subtracting the value measured by the laser rangefinder 30 from the depth of the measuring tube 20 and the fixed distance between the laser rangefinder 30 and the liquid surface. Here, the float body 10 can also be installed with the liquid level measuring element of the magnetic float level gauge in the prior art to measure the liquid level. The upper end of the measuring cylinder 20 is equipped with a cylinder cover 21. The measuring float 100 also includes: a de-impurity mechanism 40 for removing lumps in the plant liquid. The de-impurity mechanism 40 includes: a funnel-shaped bottom sleeve 41, a small electric telescopic rod 42, a small water pump 43, a liquid sensing switch 44, a filter body 45, a linkage mechanism 46, a blocking conduction mechanism 47 and an external discharge mechanism 48. The funnel-shaped bottom sleeve 41 is arranged at the bottom of the float body 10, and the larger end of the funnel-shaped bottom sleeve 41 is upward. The small electric telescopic rods 42 are vertically buried in pairs on the inner side of the bottom of the float body 10, and the lower end of the small electric telescopic rod 42 is a telescopic end. The telescopic end of the small electric telescopic rod 42 is fixedly connected to the funnel-shaped bottom sleeve 41, and there is a gap between the original position of the funnel-shaped bottom sleeve 41 and the bottom of the floating block body 10, which facilitates the plant liquid and block in the measuring tube 20 to enter the funnel-shaped bottom sleeve 41, and due to the funnel shape of the funnel-shaped bottom sleeve 41, they are gathered at the middle position of the bottom. The small electric telescopic rod 42 is sealed and waterproof elements are used to avoid damage caused by contact with liquid. At the same time, the small electric telescopic rod 42 is equipped with a remote control switch. The small water pump 43 is fixedly installed at the bottom of the funnel-shaped bottom sleeve 41, and the water suction end of the small water pump 43 is connected to the inner space of the funnel-shaped bottom sleeve 41. The filter body 45 is installed at the middle position of the bottom of the funnel-shaped bottom sleeve 41. The liquid sensing switch 44 is installed at the outside of the bottom of the funnel-shaped bottom sleeve 41. The liquid sensing switch 44 is electrically connected to the small water pump 43. The blocking conduction mechanism 47 is installed at the middle position inside the floating block body 10. And the linkage mechanism 46 is connected between the blocking conduction mechanism 47 and the small electric telescopic rod 42. The external discharge mechanism 48 is installed to the top of the measuring cylinder 20.

[0025] When the prepared plant liquid is poured into the measuring cylinder 20, the liquid sensing switch 44 on the funnel-shaped bottom sleeve 41 at the bottom of the floating block 10 generates an induction, and the small water pump 43 starts to operate. As the amount of liquid poured in gradually increases, the floating block 10 rises with the liquid level under the action of buoyancy. During the rising process, the liquid and the block in the measuring cylinder 20 also enter the inner space of the funnel-shaped bottom sleeve 41. At the same time, the small water pump 43 continuously extracts the liquid entering the funnel-shaped bottom sleeve 41. At the same time, since the filter body 45 is installed at the port of the small water pump 43 connected to the funnel-shaped bottom sleeve 41, the block in the liquid is blocked in the funnel-shaped bottom sleeve 41. In this way, the small water pump 43 continuously allows the liquid entering the measuring cylinder 20 to continuously pass through the funnel-shaped bottom sleeve 41, thereby concentrating the mixed block in the funnel-shaped bottom sleeve 41. And when the prepared liquid is completely poured into the measuring cylinder 20, the small electric telescopic rod 42 is controlled by the remote control switch to shrink. In this way, the small electric telescopic rod 42 drives the funnel-shaped bottom sleeve 41 to rise and dock with the bottom of the floating block 10, and the collected blocks are sealed in the inner space of the funnel-shaped bottom sleeve 41 to prevent the blocks from interfering with the liquid level measurement of the measuring element on the floating block 10. At the same time, when the small electric telescopic rod 42 is retracted, the linkage mechanism 46 causes the blocking conduction mechanism 47 to open. And the blocking conduction mechanism 47 is linked to dock to the middle position of the bottom of the funnel-shaped bottom sleeve 41, and the upper end of the blocking conduction mechanism 47 is opened. Then the external discharge mechanism 48 is controlled to run and dock to the upper open position of the blocking conduction mechanism 47, and then the blocks at the bottom of the funnel-shaped bottom sleeve 41 are discharged by the negative pressure, so that the liquid level measuring element on the floating block 10 can effectively measure.

[0026] The upper end surface of the floating block body 10 is a convex spherical surface with a protrusion in the middle, which facilitates the block and liquid falling on the upper side of the floating block body 10 to flow toward the edge and fall.

[0027] The inner wall of the funnel-shaped bottom sleeve 41 is coated with a lubricant for reducing friction.

[0028] The blocking conduction mechanism 47 includes: a through-port 471, a splicing ring 472, a fixed embedded tube 473, a telescopic slide 474, a connecting spring 475 and a closed splicing block 476. The through-port 471 is vertically opened in the middle position of the floating block body 10. The splicing ring 472 is connected to the upper end of the through-port 471. The fixed embedded tube 473 is vertically connected to the inner side of the through-port 471, and the upper end of the fixed embedded tube 473 is spliced ​​together with the splicing ring 472. At the same time, the fixed embedded tube 473 is fixedly connected to the floating block body 10. The telescopic slide 474 slides vertically and is inserted into the lower end of the fixed embedded tube 473. The connecting spring 475 is connected between the telescopic slide 474 and the fixed embedded tube 473. The closed splicing block 476 is movably connected to the inner side of the upper port of the fixed embedded tube 473 through a rebound hinge, and there are multiple closed splicing blocks 476, which are spliced ​​into a round block to close the upper port of the fixed embedded tube 473.

[0029] The splicing ring 472, the fixed embedded tube 473 and the closed splicing block 476 are assembled into a complete block, and the upper end of the through port 471 is closed to facilitate the block falling on the upper side of the floating block body 10 to slide to the edge.

[0030] The closed splicing block 476 is a rubber piece used for sealing.

[0031] The fixed embedded tube 473 and the telescopic sliding tube 474 are both plastic tubes.

[0032] The blocking conduction mechanism 47 further includes an auxiliary suction port 477 . The auxiliary suction port 477 is equidistantly arranged around the lower end side wall of the telescopic slide tube 474 , and the auxiliary suction port 477 facilitates the telescopic slide tube 474 to suck away the block in the funnel-shaped bottom sleeve 41 .

[0033] The linkage mechanism 46 includes: a linkage frame 461, a first linkage line 462, a fixed pulley 463 and a second linkage line 464. The linkage frame 461 is fixedly connected between the splicing ring 472 and the telescopic end of the small electric telescopic rod 42. The fixed pulleys 463 are fixedly installed in pairs to the inner bottom of the funnel-shaped bottom sleeve 41. The first linkage line 462 is connected between the lower end of the telescopic slide tube 474 and the linkage frame 461. At the same time, the first linkage line 462 bypasses the bottom of the fixed pulley 463. The lower side of each closed splicing block 476 is connected to the second linkage line 464. The end of the second linkage line 464 passes through the inner side of the fixed embedded tube 473 and is connected to the bottom of the splicing ring 472.

[0034] The first linkage line 462 and the second linkage line 464 are both steel wires.

[0035] When the small electric telescopic rod 42 is retracted, the linkage frame 461 rises accordingly, pushing the splicing ring 472 up from the port of the through port 471. At the same time, the linkage frame 461 pulls the first linkage line 462, and the first linkage line 462 pulls the telescopic slide tube 474 downward to the middle position of the bottom of the funnel-shaped bottom sleeve 41 by the steering of the fixed pulley 463. At the same time, when the splicing ring 472 is raised, it pulls the closed splicing block 476 spliced ​​and closed at the port of the fixed embedded tube 473 through the second linkage line 464 to rotate downward, so that the port of the fixed embedded tube 473 is opened.

[0036] The external discharge mechanism 48 includes: a main electric telescopic rod 481, a dust collector assembly 482, a butt joint 483 and a storage box 484. The main electric telescopic rod 481 is vertically fixedly connected to the outer wall of the measuring cylinder 20, and the upper end of the main electric telescopic rod 481 is a telescopic end. The dust collector assembly 482 is fixedly mounted to the upper end of the main electric telescopic rod 481. The butt joint 483 is vertically connected to the negative pressure end of the dust collector assembly 482. At the same time, the butt joint 483 vertically slides and inserts into the cylinder cover 21. The storage box 484 is mounted to the discharge end of the dust collector assembly 482.

[0037] When the prepared liquid is completely poured into the measuring tube 20, and the upper port of the fixed embedded tube 473 in the blocking conduction mechanism 47 is opened, the main electric telescopic rod 481 is controlled to shrink, so that the docking tube 483 slides down and docks with the upper open port of the fixed embedded tube 473. Then the vacuum cleaner assembly 482 is started, so that the negative pressure generated by it acts on the inner bottom of the funnel-shaped bottom sleeve 41 through the telescopic slide tube 474, and the block is sucked away and discharged into the storage box 484. In this way, it is convenient for the floating block body 10 to effectively measure the liquid level through the assembly for measuring the liquid level.
