Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level detection, and in particular relates to a high-repeatability liquid level capturing device. Background Art

[0002] The liquid level capture device is a device used to capture changes in water level. Some devices need to be fixed near the water surface. When the liquid level capture device detects changes in water level, it sends a signal to cause other devices to perform lifting and other operations to keep them at a suitable distance from the water surface at all times.

[0003] When existing liquid level capture devices need to be fixed, most of them will use bolt connections. However, when the liquid level capture device needs to be installed on a tank body or a kettle body, since the surface of the tank body or the kettle body is relatively smooth and there are no reserved mounting holes, or the mounting holes cannot be adapted to the liquid level capture device, the liquid level capture device cannot be installed normally, which has certain limitations.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 7 As shown, the utility model is a highly repeatable liquid level capturing device, comprising a fixed plate 1, a displacement assembly 2 is arranged inside the fixed plate 1, a connecting assembly 3 is fixedly connected to the bottom of the displacement assembly 2, an electric push rod 4 is fixedly connected to the bottom of the fixed plate 1, a square plate 5 is fixedly connected to the movable end of the electric push rod 4, a laser emitter 6 and a laser receiver 7 are fixedly connected to the bottom of the square plate 5, a distance detector 9 is clamped on the top of the square plate 5, the displacement assembly 2 is used to drive the connecting assembly 3 to move, the connecting assembly 3 is used to connect and fix, and the laser emitter 6 and the laser receiver 7 are used to capture the horizontal plane.

[0031] The displacement component 2 drives the connection component 3 to move, so that the two groups of connection components 3 are separated from each other, and then the two groups of connection components 3 are respectively placed on the inner and outer sides of the tank or kettle body. The displacement component 2 drives the connection components 3 to approach each other and clamp the tank or kettle body to complete the fixation of the fixed plate 1, and then the electric push rod 4 on the fixed plate 1 is started to push the square plate 5, the laser transmitter 6 and the laser receiver 7 to descend. The laser transmitter 6 emits a light beam and is received by the laser receiver 7. Due to the different propagation rates of light in air and liquid, when the laser receiver 7 detects a change in the light signal, it means that it is now on the water surface. The laser transmitter 6 continues to emit light signals. When the water surface height changes, the laser receiver 7 can receive the change and transmit information in the first time to make the electric push rod 4 perform lifting and lowering operations. At the same time, the distance detector 9 on the square plate 5 can detect the distance between the water surface and the bottom of the water, so that the staff can understand the information more comprehensively.

[0032] The utility model connects the displacement component 2 and the connection component 3. The displacement component 2 can drive the connection component 3 to move, so that the connection components 3 are separated from or approached from each other. When the connection components 3 are at different distances, they can be fixed on tanks or kettles with different thicknesses. At the same time, the connection component 3 and the displacement component 2 are detachably connected, which is convenient for replacing the connection component 3 so that it can adapt to tanks or kettles with different signals. The connection component 3 is clamped on the side wall of the tank or kettle for fixing. This method does not require reserved holes and is more flexible to use.

[0033] In one embodiment, for the above-mentioned displacement assembly 2, the displacement assembly 2 includes a screw rod 201, the outer surface of which is fixedly connected to a hand wheel 202, the screw rod 201 is rotatably connected to a fixed plate 1, the outer surface of the screw rod 201 is threadedly connected to a slider 203, and the slider 203 is slidably connected to the fixed plate 1.

[0034] The hand wheel 202 is rotated to drive the screw 201, and the screw 201 drives the slider 203. The slider 203 is blocked by the fixed plate 1, so that the slider 203 cannot rotate. At this time, the screw 201 can drive the slider 203 to make a linear motion along the fixed plate 1.

[0035] In one embodiment, for the above-mentioned connecting component 3, the connecting component 3 includes a turning handle 301, the outer surface of the turning handle 301 is fixedly connected with a first bolt 302, the first bolt 302 is threadedly connected to the slider 203, the slider 203 is fixedly connected with a connecting block 303 through the first bolt 302, the bottom of the connecting block 303 is fixedly connected with a clamping plate 304, the bottom of the fixing plate 1 is fixedly connected with a connecting plate 305, and the outer surface of the connecting plate 305 is provided with a screw hole 306.

[0036] The slider 203 drives the connecting block 303 and the clamping plate 304 to move, thereby changing the distance between the clamping plates 304. When the clamping plates 304 are close to each other, they can clamp the side wall of the tank body or kettle body to fix it. When the clamping plate 304 is not suitable for the current tank body or kettle body, the rotating handle 301 drives the first bolt 302 to separate the first bolt 302 from the connecting block 303. The clamping plate 304 and the connecting block 303 can be removed and replaced, which is more flexible to use.

[0037] In one embodiment, for the square plate 5 , a clamping assembly 8 is fixedly connected to the top of the square plate 5 , and the square plate 5 is fixedly connected to the distance detector 9 via the clamping assembly 8 .

[0038] In one embodiment, for the above-mentioned snap-in assembly 8, the snap-in assembly 8 includes a vertical plate 801, the internal sliding connection of the vertical plate 801 is a round rod 802, the top of the round rod 802 is fixedly connected to a pressing plate 803, the outer surface of the round rod 802 is fixedly connected to a sliding plate 804, the bottom of the sliding plate 804 is fixedly connected to a first spring 805, the internal sliding connection of the vertical plate 801 is a card block 806, the card block 806 is plugged into the distance detector 9, and the outer surface of the card block 806 is fixedly connected to a second spring 807.

[0039] By pressing the pressing plate 803, the pressing plate 803 drives the round rod 802 to move downward, and the round rod 802 drives the sliding plate 804 to compress the first spring 805. At the same time, the round rod 802 squeezes the block 806, so that the block 806 is separated from the distance detector 9 and compresses the second spring 807. At this time, the distance detector 9 can be taken out and removed from the vertical plate 801. After releasing the pressing plate 803, the first spring 805 pushes the sliding plate 804 and the round rod 802 to reset, and the round rod 802 moves upward and separates from the block 806. The second spring 807 pushes the block 806 to reset and plug it into the distance detector 9, thereby fixing the distance detector 9. The installation and disassembly of the distance detector 9 is relatively simple, and it can be removed for storage when not in use.

[0040] In one embodiment, for the laser emitter 6 , the outer surfaces of the laser emitter 6 and the laser receiver 7 are both threadedly connected with second bolts 10 , and the second bolts 10 extend to the inside of the square plate 5 .

[0041] In one embodiment, for the above-mentioned fixing plate 1 , a battery 11 is fixedly connected to the top of the fixing plate 1 , and the battery 11 is electrically connected to the electric push rod 4 .

[0042] Removing the second bolt 10 can release the limiting fixation of the laser emitter 6 and the laser emitter 7, making it easy to remove and store them. The battery 11 can supply power to the electric push rod 4.

[0043] Through the above technical solution, 1. Through the connection between the displacement component 2 and the connection component 3, the displacement component 2 can drive the connection component 3 to move, so that the connection components 3 are moved away from or close to each other. When the connection components 3 are at different distances, they can be fixed on tanks or kettles of different thicknesses. At the same time, the connection component 3 and the displacement component 2 are detachably connected, which is convenient for replacing the connection component 3 so that it can adapt to tanks or kettles with different signals. The connection component 3 is clamped on the side wall of the tank or kettle for fixation. This method does not require reserved holes and is more flexible to use. 2. Through the connection between the slider 203 and the connecting block 303, the slider 203 can drive the connecting block 303 and the clamping plate 304 to move, and the distance between the clamping plates 304 can be changed, so that the clamping plate 304 can clamp and fix tank bodies or kettle bodies of different thicknesses. At the same time, after removing the first bolt 302, the limit fixation of the connecting plate 303 can be released. At this time, the connecting plate 303, the clamping plate 304 and the slider 203 can be separated, which is convenient for replacing the clamping plate 304, so that it can better adapt to tank bodies and kettle bodies of different models, avoid the situation where it cannot be fixed, and use it more flexibly.
