Description

Technical Field

[0001] This utility model relates to the field of liquid level monitoring technology, and in particular to a liquid level monitoring device. Background Technology

[0002] The collection tank for wastewater from the condensate recovery equipment is very small, only 1 meter deep, and relies on a traditional float level switch to control the water pump for drainage. Due to the high temperature of the condensate entering the tank and the need for electrical connections at the sensing end, the float level sensor frequently malfunctions due to high temperatures. Since the tank needs frequent drainage, if the level switch malfunction is not detected in time, water can easily overflow, causing flooding. Furthermore, the existing technology lacks an overflow sensor, resulting in incomplete water level monitoring. Additionally, when the float rises, it is only guided by the connector, and the float itself may still move horizontally, leading to inaccurate level monitoring.

[0003] Therefore, there is an urgent need to design a liquid level detection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a liquid level monitoring device that can prevent the sensing end from contacting the liquid, thereby keeping the sensing end away from high-temperature areas and preventing the sensing element from failing due to high temperatures. It also adds an overflow warning, making the monitoring more comprehensive, and guides the floating parts and connecting parts to improve the accuracy of liquid level monitoring.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Liquid level monitoring device, including:

[0007] The floating component includes a floating element, a connecting element, and a trigger element connected sequentially from bottom to top;

[0008] A guide tube includes a hollow first guide portion, at least a portion of which extends along the Z direction and is located below the liquid surface; the diameter of the first guide portion matches the floating member, which can float within the first guide portion; the connecting member extends along the Z direction; the guide tube also includes a second guide portion, which covers the upper opening of the first guide portion and has a guide hole; the connecting member passes through the guide hole, and the cross-sectional shape of the guide hole matches the shape of the connecting member.

[0009] The sensing component includes a mounting piece and three sensors. The three sensors are energized. The mounting piece extends along the Z direction and is located beside the floating component. The three sensors are spaced apart from bottom to top on the mounting piece. When the triggering piece is at the same height as the corresponding sensor, the corresponding sensor is triggered. The three sensors, from bottom to top, are a low liquid level sensor, a high liquid level sensor, and an overflow sensor.

[0010] As an alternative, the guide tube further includes a water inlet, which is connected at an angle to the bottom of the first guide section, and the free end of the water inlet has a water inlet.

[0011] As an alternative, the floating component is a sphere, and the connecting component is cylindrical.

[0012] As an alternative, the trigger is a magnet and the sensing element is a magnetic reed.

[0013] As an alternative, the aforementioned mounting component is provided with a water level scale, and the aforementioned trigger is used to indicate the aforementioned scale.

[0014] As an alternative, the top of the trigger is horizontally positioned and used to indicate the scale lines.

[0015] As an alternative, the aforementioned guide tube is a non-magnetic component; and / or

[0016] The aforementioned mounting components are non-magnetic.

[0017] As an optional feature, the height of each of the aforementioned sensors is adjustable.

[0018] As an optional solution, the aforementioned trigger and the aforementioned connector can be detachably configured; and / or

[0019] The aforementioned floating component and the aforementioned connecting component are detachable.

[0020] As an optional solution, the aforementioned overflow sensor and alarm device are connected in communication.

[0021] The beneficial effects of this utility model are:

[0022] This invention provides a liquid level monitoring device. It comprises a low-level sensor, a high-level sensor, and an overflow sensor arranged sequentially from bottom to top. As the liquid level rises, a floating component gradually rises, causing a trigger component to rise as well. The trigger component, in conjunction with the three sensors, monitors the liquid level. Specifically, when the trigger component is at the same height as the overflow sensor, it indicates that the liquid level is too high and an overflow has occurred, allowing the operator to immediately take appropriate emergency measures. Simultaneously, a guide tube is used, with at least a portion of the first guide section below the liquid level. Water enters the first guide section from the bottom of the guide tube. The first guide section guides the floating component along the Z-direction as it floats with the liquid level. Combined with the guide hole, the two guides work together to prevent the floating component from swaying laterally with the liquid level, ensuring that the movement direction of the trigger component at the top of the floating component does not deviate, thereby improving the accuracy of the monitoring.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] This embodiment provides a liquid level monitoring device that can prevent the sensing element from failing due to high temperatures, while adding overflow warning, providing more comprehensive monitoring, and guiding the floating element 11 and the connecting element 12 to improve the accuracy of liquid level monitoring. Figure 1 As shown, the liquid level monitoring device includes a floating assembly 10, a guide tube 20, and a sensing assembly 30. The floating assembly 10 includes a floating element 11, a connecting element 12, and a trigger element 13 connected sequentially from bottom to top. The guide tube 20 includes a hollow first guide portion 21, at least a portion of which extends along the Z direction and is located below the liquid surface. The diameter of the first guide portion 21 matches that of the floating element 11, allowing the floating element 11 to float within the first guide portion 21. The connecting element 12 extends along the Z direction. The guide tube 20 also includes a second guide portion 22, which covers the first guide portion 21. The upper opening of component 1 has a guide hole 221, through which the connector 12 passes. The cross-sectional shape of the guide hole 221 matches the shape of the connector 12. The sensing component 30 includes a mounting component 31 and three sensors. The three sensors are energized. The mounting component 31 extends along the Z direction and is located beside the floating component 10. The three sensors are spaced apart from bottom to top on the mounting component 31. When the trigger 13 is at the same height as the corresponding sensor, the corresponding sensor is triggered. The three sensors from bottom to top are a low liquid level sensor 32, a high liquid level sensor 33, and an overflow sensor 34.

[0035] The aforementioned liquid level monitoring device, through a series of sensors arranged from bottom to top—a low-level sensor 32, a high-level sensor 33, and an overflow sensor 34—causees the floating component 11 to gradually rise as the liquid level rises, driving the trigger component 13 to rise as well. The trigger component 13, in conjunction with the three sensors, monitors the liquid level. In particular, when the trigger component 13 is at the same height as the overflow sensor 34, it indicates that the liquid level is too high and an overflow has occurred, allowing the operator to immediately take appropriate emergency measures. Simultaneously, a guide tube 20 is used, with at least a portion of the first guide section 21 below the liquid level. Water enters the first guide section 21 from the bottom of the guide tube 20. The first guide section 21 guides the floating component 11 along the Z-direction as it floats with the liquid level. In conjunction with the connecting component 12, which is guided by the guide hole 221, the two guides work together to prevent the floating component 11 from swaying laterally with the liquid level, ensuring that the movement direction of the trigger component 13 at the top of the floating component 10 does not deviate, thereby improving the accuracy of the monitoring.

[0036] Optionally, such as Figure 1 and Figure 2 As shown, the guide tube 20 also includes a water inlet 23, which is connected at an angle to the bottom of the first guide section 21. The free end of the water inlet 23 has a water inlet 231. Through the above arrangement, the bending section of the guide tube 20 is increased, so that the water entering the first guide section 21 can be more stable, thereby improving the stability of the entire floating assembly 10.

[0037] In this embodiment, the water inlet 23 is arranged perpendicularly to the first guide 21. In other embodiments, the water inlet 23 may also be arranged at an obtuse angle to the first guide 21, which is not limited here.

[0038] Optionally, such as Figure 1 As shown, the floating component 11 is a sphere, and the connecting component 12 is cylindrical. This arrangement ensures that when the sphere floats within the first guide portion 21, the friction between the sphere and the first guide portion 21 is minimized. The cylindrical shape of the connecting component 12 prevents sliding jamming caused by ridges on its circumferential surface.

[0039] Optionally, the trigger element 13 is a magnet, and the sensing element is a magnetic reed. When the magnet approaches the magnetic reed, the magnetic reed closes, the circuit is connected, and a signal is generated accordingly.

[0040] Optionally, such as Figure 1 As shown, the mounting component 31 is equipped with a water level scale line 40, and the trigger 13 is also used to indicate the scale line 40. With the above settings, by observing the position of the scale line 40 indicated by the trigger 13, the operator can know the current water level in real time.

[0041] Optionally, the top of the trigger 13 is horizontally positioned and used to indicate the scale line 40. Specifically, the trigger 13 is constructed as a cuboid for ease of manufacture and installation, and the horizontal position of the top provides greater accuracy for indicating the scale line 40 and facilitates observation.

[0042] Optionally, the guide tube 20 is a non-magnetic component; this prevents the trigger 13 from contacting the guide tube 20 when it is at its lowest position, causing the two to adhere together. The buoyancy force on the floating component 11 makes it difficult to separate the two, resulting in floating failure and abnormal monitoring.

[0043] Optionally, the mounting part 31 is a non-magnetic part to prevent the mounting part 31 from affecting the sensing effect of the sensing element. For the magnetic reed, if the mounting part 31 is magnetic, it will affect the closing of the magnetic reed, causing the magnetic reed to be in a normally closed state, resulting in misjudgment of the liquid level.

[0044] Optionally, the height of each sensor is adjustable. Therefore, the height of each sensor can be adjusted according to different pool depths. In this embodiment, the mounting member 31 is installed on the pool wall, with its lower part below the liquid surface and its upper part above the liquid surface. The sensors are connected to their corresponding positions on the mounting member 31 via clamps to achieve height adjustment.

[0045] Optionally, the trigger 13 and the connector 12 are detachable, and the trigger 13 can be easily replaced if it is damaged.

[0046] Optionally, the floating component 11 and the connecting component 12 are detachable. Further, the second guide portion 22 and the first guide portion 21 are detachable. First, the second guide portion 22 is removed from the top of the first guide portion 21, and then the floating component 10 is removed from the first guide portion 21 as a whole, so that the floating component 11 can be replaced.

[0047] Optionally, the overflow sensor 34 is communicatively connected to the alarm device. With the above configuration, an alarm can be triggered promptly upon the occurrence of an overflow, allowing for appropriate emergency measures to be taken. Optionally, the alarm device can be a buzzer or a flashing light, etc., and is not limited thereto.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
