Description

Technical Field

[0001] This utility model belongs to the field of liquid level controller technology, specifically, it relates to a float switch device with multi-color indicator lights. Background Technology

[0002] A float switch is an automated device that uses the principle of buoyancy to detect and control liquid levels. It uses a float that moves up and down on the liquid surface to trigger an internal mechanical or electrical switch, thus opening or closing the circuit or outputting a signal. Float switches are widely used in water tanks, oil tanks, sewage treatment, agricultural irrigation and other applications to automatically monitor and regulate liquid levels and prevent overflow or dry pumping.

[0003] As shown in the existing technology, such as the float switch provided at the link: https: / / v.douyin.com / cdX-VHk7-gk / , the float switch is connected to a single-color indicator light. When the operator is performing liquid level detection, the single-color indicator light illuminates when the float moves up to the preset liquid level height, and turns off when the float moves down, thus facilitating timely adjustment of the liquid level by the operator.

[0004] However, in actual liquid level detection work, the single-color indicator light of the float will only light up when the set liquid level height is reached. Therefore, when the float switch is working normally but the liquid level has not reached the preset height, or when the float switch malfunctions, the indicator light will remain off. At this time, the on / off state of the single-color light alone cannot accurately determine whether the float switch is working normally, which has certain limitations. Utility Model Content

[0005] To address the technical problem that existing single-color indicator float switches remain off when working normally but not reaching the preset liquid level, or when the float switch malfunctions, making it impossible to accurately determine whether the float switch is working properly, this utility model provides a float switch device with multi-color indicator lights.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A float switch device with multi-color indicator lights includes a liquid level tube; an LED light is connected to the upper part of the liquid level tube; characterized in that: a hollow connecting rod is provided below the liquid level tube, and the connecting rod is connected to the liquid level tube; a reed switch is fixedly provided in the upper part of the connecting rod, and the reed switch is electrically connected to the LED light; a float is slidably connected to the connecting rod, and the float slides on the connecting rod under the action of buoyancy of the liquid and its own weight; a magnetic ring is fixedly provided inside the float; a limit block is provided in the lower part of the connecting rod.

[0008] Furthermore, a pipe clamp is provided on the liquid level tube, and the pipe clamp is located below the LED light.

[0009] Furthermore, one end of the pipe clamp is threadedly connected to a first bolt.

[0010] Furthermore, multiple floats at different heights are fixedly mounted on the connecting rod; reed switches are correspondingly mounted on the connecting rod at the positions of the floats; each reed switch corresponds to an LED light color.

[0011] Furthermore, two fixing plates are provided between each pair of adjacent floats. The upper fixing plate restricts the lowest position of the upper float, and the lower fixing plate restricts the highest position of the lower float.

[0012] Furthermore, each of the fixing plates is provided with a second bolt.

[0013] Furthermore, the LED light is fixedly provided with an electrical connection terminal; a cable is connected to the terminal.

[0014] Furthermore, a drop line is connected to the bottom of the limiting block; a counterweight is fixedly connected to the bottom end of the drop line, and the weight of the counterweight keeps the float switch in a vertical state.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model sets the float switch to a red light in the initial state, and the LED light to a green light when the float switch is working normally and reaches the preset liquid level. The use of two colors of light helps operators judge the working status of the float switch, which solves the technical problem in the prior art where the single-color indicator float switch remains off when it is working normally but has not reached the preset liquid level, or when the float switch malfunctions, making it impossible to accurately judge whether the float switch is working normally.

[0017] 2. This utility model has multiple floats slidably mounted on the connecting rod at different heights. The buoyancy of the liquid drives the floats to move up and down, thereby causing the magnetic ring to contact the reed switch at different heights as the liquid level rises. The LED light displays colors other than red and green (such as yellow and blue). At this time, the operator can judge the liquid level based on the different colors and perform liquid adjustment work, which is convenient, quick and practical.

[0018] 3. This utility model uses a counterweight at the bottom of the limiting block to ensure that the float switch remains vertical during liquid level detection, preventing it from tilting and ensuring measurement accuracy. This allows operators to better judge the liquid level and reduces errors. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1 - Figure 2 As shown, a float switch device with multi-color indicator lights includes a liquid level tube 1; an LED light 2 is connected to the upper part of the liquid level tube 1; a tube clamp 5 is provided on the liquid level tube 1, which is used to fix the position of the liquid level tube 1 and is located below the LED light 2; a first bolt 6 is threaded to one end of the tube clamp 5, which is used to fix and remove the tube clamp 5; an electrical connection terminal 7 is fixedly provided on the LED light 2; a cable 8 is connected to the terminal 7, which is used to connect to a power source.

[0029] A hollow connecting rod 10 is provided below the liquid level tube 1, and the connecting rod 10 is connected to the liquid level tube 1; a reed switch 9 is fixedly installed in the upper part of the connecting rod 10, and the reed switch 9 is electrically connected to the LED light 2; a float 3 is slidably connected to the connecting rod 10, and the float 3 slides on the connecting rod 10 under the action of the buoyancy of the liquid and its own weight; a magnetic ring 13 is fixedly installed inside the float 3, and the magnetic ring 13 is used to apply a magnetic field to the reed switch 9; a limit block 4 is provided at the lower part of the connecting rod 10, and the limit block 4 is used to prevent the float 3 from falling off the connecting rod 10.

[0030] It is worth noting here that the reed switch 9 in this embodiment is existing technology, and its specific structure and working principle will not be described in detail here.

[0031] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0032] In practical use, the operator places the float switch in the device to be used for liquid level detection and connects the cable 8 to the power supply. At this time, the float 3 moves to the bottom of the connecting rod 10 under the action of gravity. The magnetic field range of the magnetic ring 13 inside the float 3 is far away from the reed switch 9, and the reed switch 9 is in the open state, causing the LED light 2 to turn red.

[0033] When the liquid level changes, float 3 moves upward on connecting rod 10 under the buoyancy of the liquid. The magnetic ring 13 inside float 3 also moves upward synchronously until the magnetic ring 13 inside float 3 moves to the position of reed switch 9 (the position of reed switch 9 is the preset liquid level). The magnetic field of the magnetic ring 13 inside float 3 enters the range of reed switch 9, the circuit is connected, and LED 2 turns green. At this time, the float switch is in normal working condition.

[0034] This invention solves the technical problem in the prior art where a single-color indicator float switch illuminates a red light in its initial state, and turns green when the float switch reaches the preset liquid level. This allows operators to determine the working status of the float switch by using two colors of light.

[0035] Example 2:

[0036] Please refer to it again. Figures 3-4As shown, this utility model is a float switch device with multi-color indicator lights. This embodiment is basically the same in structure as the first embodiment, except that in this embodiment, multiple floats 3 at different heights are fixedly installed on the connecting rod 10 (three are installed in this embodiment); reed switches 9 are installed on the connecting rod 10 corresponding to the positions of the floats 3; each reed switch 9 corresponds to a color of LED light 2; two fixing plates 14 are installed between two adjacent floats 3, the upper fixing plate 14 is used to limit the lowest position of the upper float 3, and the lower fixing plate 14 is used to limit the highest position of the lower float 3; each fixing plate 14 is provided with a second bolt 15, which is used to fix and remove the fixing plate 14.

[0037] In actual operation, when the float switch is in its initial state, LED 2 is red. When the liquid height changes, under the buoyancy of the liquid, the float 3 at the bottom of the connecting rod 10 moves upward on the connecting rod 10. Since there is a magnetic ring 13 inside the float 3, the upward movement of the float 3 drives the magnetic ring 13 to move upward. When the magnetic ring 13 contacts the corresponding reed switch 9, LED 2 turns green.

[0038] As the liquid level rises, the magnetic rings 13 inside the different floats 3 sequentially contact the reed switches 9 at different heights. The LED lights 2 display colors other than red and green (such as yellow and blue). At this time, the operator can judge the liquid level based on the different colors and perform liquid level adjustment work, which is convenient, quick and practical.

[0039] Example 3:

[0040] Please see Figure 5 As shown, this utility model is a float switch device with multi-color indicator lights. This embodiment is basically the same in structure as the first embodiment. The difference is that in this embodiment, the bottom of the limiting block 4 is connected to a drop line 11; the bottom end of the drop line 11 is fixedly connected to a counterweight block 12.

[0041] This invention uses a counterweight 12 at the bottom of the limiting block 4. The weight of the counterweight 12 ensures that the float switch remains vertical during liquid level detection, preventing it from tilting and guaranteeing measurement accuracy. This allows operators to better judge the liquid level and reduces errors.
