Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid level gauge technology, specifically to a mechanical liquid level display device. Background Technology
[0002] Chinese patent CN220853786U discloses a tar tank float level gauge, comprising a chute and a flange for fixed connection to the tar tank. Vertical guide tubes are fixed to both the chute and the flange. Two connecting plates are fixed to each vertical guide tube, and guide pulleys are bolted between the two connecting plates. Steel wire ropes are connected to the two guide pulleys, passing through the two vertical guide tubes. A counterweight and a float are fixed to each end of the steel wire rope. Outward-folding baffles are provided on both sides of the chute, with graduation lines on the baffles. In use, the operator connects the device to the tar tank, with the float at the bottom and the counterweight at the top of the chute. Coal tar is introduced, causing the float to rise and the counterweight to fall. The tar level in the tank is determined by reading the measurement. The outward-folding baffles fit snugly against the tank body, preventing bending or deformation that could jam the counterweight during strong winds, thus avoiding the inability to accurately determine the coal tar level.
[0003] However, in the above structure, the buoy will move irregularly with changes in the liquid level. When the buoy moves irregularly, it will cause the wire rope to twist. The twisted wire rope may generate additional friction or resistance, which will hinder the buoy from rising or falling. This will cause the buoy to not accurately follow the changes in the liquid level, thus causing the detection results to be inaccurate. At the same time, the weight is not limited. When the liquid level fluctuates significantly, the wire rope will be sometimes tight and sometimes loose, which will easily cause the weight to shake. The shaking weight will also cause the wire rope to twist.
[0004] Based on this, the present invention designs a mechanical liquid level display device to solve the above problems. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mechanical liquid level display device.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

The ball is rotatably connected inside the lower limit ring and the upper limit ring.
[0010] A connecting rope is fixedly attached to the top of the sphere;
[0011] The connecting rope is movably connected to a guide assembly for guiding the connecting rope.

The bottom of the second connecting pipe is fixedly connected to a display assembly for liquid level display, and the display assembly is fixedly connected to the connecting rope.
[0012] Furthermore, the guide assembly includes a housing, a first fixed pulley, and a second fixed pulley. The first fixed pulley and the second fixed pulley are symmetrically fixedly connected to the bottom ends of the housing. The second fixed pulley is located above the first connecting pipe, and the first fixed pulley is located above the second connecting pipe. The first fixed pulley and the second fixed pulley are slidably connected to the outer edge of the connecting rope.
[0013] Furthermore, the top of the enclosure is open, and a movable cover assembly is connected to the top of the enclosure to facilitate the installation and operation of the connecting rope inside the enclosure.
[0014] Furthermore, the movable cover assembly includes a cover body, a hinge, a connecting block, a first magnet, and a second magnet.

[0019] Beneficial effects
[0020] This invention fixes the first connecting pipe to the top of the container, with a float placed inside. As the liquid level changes, the float moves accordingly, driving the connecting rope to move. The connecting rope then drives the display component to display the liquid level, facilitating liquid level monitoring. The lower and upper limit rings of the universal connecting component work together to allow the float to rotate in all directions, better adapting to the float's movement in different directions. This effectively prevents the connecting rope from twisting due to the float's complex movements, preventing additional friction or resistance from hindering the float's ascent or descent. This allows the float to accurately follow changes in liquid level, resulting in accurate detection results. Simultaneously, the guide component guides the connecting rope, reducing friction and facilitating smooth movement. Attached Figure Description

[0034] The present invention will be further described below with reference to the embodiments.
[0035] Example 1

[0037] The top of the float 1 is connected to a universal joint assembly 2 for universal connection;
[0038] The universal connection assembly 2 includes a ball 21, a lower limit ring 22 and an upper limit ring 23. The lower limit ring 22 is fixedly installed on the top of the float 1. The lower limit ring 22 is fixedly connected to the upper limit ring 23 by mounting screws. The ball 21 is rotatably connected inside the lower limit ring 22 and the upper limit ring 23.
[0039] A connecting rope 3 is fixedly connected to the top of the sphere 21;
[0040] The connecting rope 3 is movably connected to a guide component 5 for guiding the connecting rope 3. The bottom of both ends of the guide component 5 are respectively fixedly connected to a first connecting pipe 4 and a second connecting pipe 6. The first connecting pipe 4 is located above the float 1 and is fixedly connected to the container. The bottom of the second connecting pipe 6 is fixedly connected to a display component 7 for liquid level display, and the display component 7 is fixedly connected to the connecting rope 3.
[0041] The first connecting pipe 4 is fixedly installed on the top of the container, and the float 1 is placed inside the container. As the liquid level changes, the float 1 moves accordingly, and the float 1 drives the connecting rope 3 to move. The connecting rope 3 drives the display component 7 to display the liquid level, which facilitates liquid level monitoring of the container. The lower limit ring 22 and the upper limit ring 23 of the universal connecting component 2 cooperate to provide the ball 21 with the possibility of universal rotation, which can better adapt to the movement of the float 1 in different directions, effectively prevent the connecting rope 3 from twisting due to the complex movement of the float 1, and effectively prevent the twisted connecting rope 3 from generating additional friction or resistance that hinders the rise or fall of the float 1, so that the float 1 can accurately follow the liquid level change, thereby making the detection result accurate. At the same time, the guide component 5 guides the connecting rope 3, reduces the friction of the connecting rope 3, and facilitates the smooth movement of the connecting rope 3.
[0042] The guide assembly 5 includes a housing 51, a first fixed pulley 58 and a second fixed pulley 59. The first fixed pulley 58 and the second fixed pulley 59 are symmetrically fixedly connected to the bottom ends of the housing 51. The second fixed pulley 59 is located above the first connecting pipe 4, and the first fixed pulley 58 is located above the second connecting pipe 6. The first fixed pulley 58 and the second fixed pulley 59 are slidably connected to the outer edge of the connecting rope 3.
[0043] The first fixed pulley 58 and the second fixed pulley 59 provide rotational support for the connecting rope 3, reducing the resistance to movement of the connecting rope 3 and facilitating the transmission of liquid level data by the connecting rope 3.
[0044] The top of the housing 51 is open, and the top of the housing 51 is connected to a movable cover assembly for facilitating the installation and operation of the connecting rope 3 inside the housing 51.
[0045] The movable cover assembly includes a cover body 52, a hinge 53, a connecting block 54, a first magnet 55, and a second magnet 56. One end of the cover body 52 is rotatably connected to one end of the box body 51 via the hinge 53. The other end of the cover body 52 is fixedly connected to the connecting block 54. The first magnet 55 is fixedly connected to the connecting block 54 near the inner wall of the box body 51. The first magnet 55 and the second magnet 56 are magnetically attracted to each other. The second magnet 56 is fixedly installed at the other end of the box body 51.
[0046] The first magnet 55 and the second magnet 56 are attracted to each other, which makes it easy to fix the cover 52 onto the box 51;
[0047] When the connecting rope 3 needs to be replaced or cleaned, the first magnet 55 and the second magnet 56 are separated, the cover 52 is rotated along the hinge 53, the top of the box 51 is opened, and the box 51 is operated in an open state, which facilitates the movement of the connecting rope 3 inside the box 51.
[0048] The display component 7 includes a cylindrical body 71, a scale 72, and an indicator block 73. The cylindrical body 71 is fixedly installed at the bottom of the second connecting pipe 6. The scale 72 is fixedly connected to the inner wall of the cylindrical body 71 near the float 1. The end of the connecting rope 3 away from the float 1 is fixedly connected to the indicator block 73 for scale reading.
[0049] The graduations on the 72 scale increase from top to bottom;
[0050] The cylindrical body 71 is made of transparent acrylic material;
[0051] The outer wall of indicator block 73 is red;
[0052] The sum of the weight of indicator block 73 and the buoyancy of float 1 is equal to the weight of float 1;
[0053] When the float 1 moves upward, the connecting rope 3 loosens, and the indicator block 73 of the display component 7 moves downward. The indicator block 73 causes the connecting rope 3 to straighten, and the liquid level value is determined according to the position of the indicator block 73 on the scale 72. When the float 1 moves downward, the float 1 causes the connecting rope 3 to move, and the connecting rope 3 causes the indicator block 73 of the display component 7 to move upward. The liquid level value is determined according to the position of the indicator block 73 on the scale 72.
[0054] A guide rod 74 is fixedly connected between the bottom and top of the inner cylinder 71, and the indicator block 73 is slidably connected to the guide rod 74 through a sliding hole.
[0055] Guide rod 74 consists of two sets;
[0056] The guide rod 74 guides the movement of the indicator block 73, preventing the indicator block 73 from sliding and swinging, and enabling it to move stably in the vertical direction, further reducing the possibility of twisting of the connecting rope 3.
