Description

Technical Field

[0001] This utility model relates to the field of liquid level detection technology, and more specifically, to a top-mounted liquid level detection device resistant to magnetic field interference. Background Technology

[0002] When detecting the liquid level in the water tanks inside the factory, it can be achieved by using a top-mounted liquid level gauge. However, the display part of the top-mounted liquid level gauge generally uses a magnetic flip display, which has no ability to resist magnetic field interference and is inaccurate under magnetic field conditions. Especially in the environment of strong magnetic field in the rectifier, the strong external magnetic field causes the actual liquid level of the equipment to fail to be displayed normally, which seriously limits the application range of the top-mounted liquid level gauge.

[0003] Most existing top-mounted liquid level detection devices lack resistance to magnetic field interference, resulting in inaccurate readings in magnetic field environments. Their practicality and durability need improvement. Furthermore, a utility model patent with publication number CN222964717U discloses a top-mounted magnetic float liquid level gauge, belonging to the technical field of liquid level gauges. This gauge includes a fixed plate, an upper guide tube, and a lower guide tube. A sliding plate is slidably connected to the inner wall of the fixed plate. The upper and lower surfaces of the sliding plate are fixedly connected to the upper and lower guide tubes, respectively. A rotating ring is rotatably connected to the outer surface of the upper guide tube, and a connecting plate is fixedly connected to the outer surface of the rotating ring. This type of device also lacks resistance to magnetic field interference, resulting in inaccurate readings in magnetic field environments. Its practicality and durability need improvement.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] This embodiment installs a liquid level detection device on a water tank. The water level is detected by the internal liquid level detection component, and the result is displayed on the scale on the surface of the sleeve device. The liquid level detection component interacts with the water surface of the tank via a float, and under the action of buoyancy, it supports an indicator ball to move up and down within an anti-interference sleeve with scale markings. This allows the user to determine the water level by the relative position of the indicator ball and the scale markings. Furthermore, the liquid level detection component is made of an anti-magnetic field interference material, which improves its anti-interference capability and prevents magnetic fields from affecting the accuracy of the detection results. The specific implementation method is as follows:

[0030] like Figures 1 to 4As shown, a top-mounted liquid level detection device resistant to magnetic field interference includes a detection housing 1, an observation window 2, a scale mark 3, and a liquid level detection component 4. An anti-interference sleeve 9 is installed inside the detection housing 1, and the liquid level detection component 4 is connected inside the anti-interference sleeve 9. An observation window 2 is provided in the middle of the front of the detection housing 1, and a scale mark 3 is provided in the middle of the observation window 2. The liquid level detection component 4 includes an indicator ball 10, a connecting rod 11, and a float 12. The indicator ball 10 is installed inside the anti-interference sleeve 9 and corresponds to the scale mark 3. The bottom of the indicator ball 10 is connected to the connecting rod 11, and the connecting rod 11 passes through the bottom of the detection housing 1 and is connected to the float 12. The liquid level detection device is installed on the water tank. The water level can be detected by the liquid level detection component 4 inside the device. The detection result can be displayed by the scale mark 3 on the surface of the device. The liquid level detection component 4 interacts with the water surface of the water tank through the float 12. Under the action of buoyancy, it supports the indicator ball 10 to move up and down in the anti-interference sleeve 9 with scale mark 3. This makes it easy for the user to determine the water level by the relative position of the indicator ball 10 and the scale mark 3. At the same time, the liquid level detection component 4 has the ability to resist magnetic field interference, which can improve its own anti-interference ability and avoid the magnetic field from affecting the accuracy of the detection result.

[0031] The indicator ball 10, connecting rod 11, and float 12 are all made of anti-magnetic field plastic. Using anti-magnetic field plastic to make the entire liquid level detection assembly 4 provides excellent resistance to magnetic field interference, preventing magnetic fields from affecting the water level detection results.

[0032] An active cavity 8 is formed inside the anti-interference sleeve 9. An indicator ball 10 is slidably connected inside the active cavity 8 and is attached to the back of the scale mark 3. The indicator ball 10 can move along the length of the active cavity 8. When the float moves up and down under the action of water, the indicator ball 10 can be moved by the connecting rod 11, and the water level can be determined by the horizontal position of the indicator ball 10 and the scale mark.

[0033] The anti-interference sleeve 9 is made of transparent anti-magnetic interference material, and the inner wall of the anti-interference sleeve 9 is provided with a corrosion-resistant layer 15. By setting the anti-interference sleeve 9 inside the detection housing 1, the protection of the liquid level detection component 4 can be improved and external magnetic field interference can be reduced. The corrosion-resistant layer 15 can improve the corrosion resistance of the device itself.

[0034] The bottom of the outer casing 1 is provided with a fixed base plate 5, and several fixing bolts 6 are provided on the fixed base plate 5. The fixed base plate 5 and fixing bolts 6 can facilitate the vertical fixation of the entire device on the water tank.

[0035] A bottom hole 13 is formed in the middle of the fixed base plate 5, and a connecting rod 11 is inserted and connected inside the bottom hole 13. The bottom hole 13 facilitates the insertion and movement of the connecting rod 11. The inner diameter of the bottom hole 13 is smaller than the outer diameter of the indicator ball 10, which can form a limit.

[0036] A long, narrow protective net cover 7 is installed at the bottom of the fixed base plate 5. The protective net cover 7 is fitted over the float 12, and its surface has several mesh holes. By installing the protective net cover 7 on the outside of the float 12, the protection of the float 12 can be improved, and external collisions can be avoided from damaging the device. The protective net cover 7 is a long, narrow net post with an opening at the bottom to facilitate the normal entry of water.

[0037] A fixing assembly is provided on the back of the detection housing 1. The fixing assembly includes a telescopic rod 16 and a fixed side plate 17. The fixed side plate 17 is installed on the telescopic rod 16, and the telescopic rod 16 is threaded onto the connecting seat 18 provided on the detection housing 1. The liquid level detection device has a detachable fixing assembly on the back, and the position of the fixed side plate 17 can be adjusted by the telescopic rod 16 to facilitate the installation and fixing of the device.

[0038] A reinforcing plate 14 is installed on the outer surface of the detection housing 1. By providing the reinforcing plate 14 on the detection housing 1, its own strength can be improved, making the detection device less prone to damage.

[0039] Working Principle: The liquid level detection device is installed on the water tank. Water level is detected by the internal liquid level detection component, and the result is displayed on the scale on the device's surface. The liquid level detection component interacts with the water surface of the tank via a float, and under the action of buoyancy, it supports the indicator ball to move up and down within an anti-interference sleeve with scale markings. This allows the user to determine the water level by the relative position of the indicator ball and the scale markings. Simultaneously, the liquid level detection component is made of anti-magnetic interference material, which improves its anti-interference capability and prevents magnetic fields from affecting the accuracy of the detection results. The reinforcing plate on the detection shell increases its strength, making the detection device less prone to damage. The protective mesh on the outside of the float enhances its protection, preventing damage from external collisions. A detachable fixing component is located on the back of the liquid level detection device for easy installation and fixation. The anti-interference sleeve inside the detection shell enhances the protection of the liquid level detection component and reduces external magnetic field interference.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
