Description

Technical Field

[0001] This invention relates to the field of liquid level monitoring and alarm technology, specifically to a liquid level monitoring and linkage alarm device. Background Technology

[0002] Liquid level monitoring is commonly used for monitoring river water levels to prevent high tides, detecting river levels during the summer rainy season to prevent dangerously high liquid levels, and monitoring the volume of liquids being filled during the filling process to prevent added liquids from leaking out of the filling container.

[0003] Existing liquid level monitoring and alarm devices can trigger an alarm when the filling volume reaches a predetermined value. However, for some special liquids, such as concrete, the filling process cannot be stopped. If the filling process is stopped, solidification will occur. The alarm device can only sound the alarm but cannot stop the filling. If human intervention is not timely, the filling liquid will leak from the container. Summary of the Invention

[0004] The purpose of this invention is to provide a liquid level monitoring and alarm device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liquid level monitoring and linkage alarm device, comprising a discharge pipe, wherein a plurality of discharge ports are provided on the discharge pipe in a ring-shaped distribution, a return cylinder is fixedly connected to the bottom of the discharge pipe, a connecting cylinder is slidably connected to the bottom of the return cylinder, a float is fixedly connected to the bottom of the connecting cylinder, an alarm is fixedly connected to the discharge pipe, an alarm switch is fixedly connected to the surface of the return cylinder, a toggle block for actuating the alarm switch is fixedly connected to the top of the connecting cylinder, and a sealing return assembly is provided inside the discharge pipe. When the liquid level reaches the alarm height, if the liquid level continues to rise, the sealing return assembly controls the liquid outlet to close and the liquid to return for transport.

[0006] As a further embodiment of the present invention, the sealing reflux assembly includes a connecting ring, which is rotatably disposed inside the discharge pipe. A fixing plate is fixedly connected to the bottom of the discharge pipe. A plurality of rotating plates arranged in a ring are rotatably connected to the fixing plate. A slide rail is provided on one side of the fixing plate. A connecting shaft that slides and engages with the slide rail is fixedly connected to the bottom of the connecting ring. A protrusion is fixedly connected to the top of the rotating plates. A plurality of clamping blocks arranged in a ring are fixedly connected to the inner wall of the connecting ring. The protrusion is disposed inside the clamping blocks. A plurality of sealing plates arranged in a ring and corresponding to the discharge port are fixedly connected to the top of the connecting ring. A sliding groove is provided on one side of the outer wall of the reflux cylinder. A slider for engaging with the sliding groove is fixedly connected to the top of the connecting cylinder. A limiting frame capable of clamping the connecting shaft is fixedly connected to the top of the connecting cylinder.

[0007] As a further embodiment of the present invention, a return pipe is fixedly connected to one side of the return cylinder, and an opening for sliding of the return pipe is provided on one side of the connecting cylinder.

[0008] As a further embodiment of the present invention, a material storage tank is fixedly connected to one end of the return pipe, a connecting pipe is fixedly connected to the top of the material storage tank, a fixing frame is fixedly connected to the top of the connecting pipe, and one end of the fixing frame is fixedly connected to the top of the discharge pipe.

[0009] As a further embodiment of the present invention, a flow limiting plate is fixedly connected to the discharge pipe outside the discharge port.

[0010] As a further embodiment of the present invention, a sealing gasket is fixedly connected to the sealing plate.

[0011] As a further embodiment of the present invention, magnetic blocks with opposite magnetic poles are embedded in both ends of the rotating plate.

[0012] As a further embodiment of the present invention, the connecting ring can completely cover the top of the slide.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By adopting a sealing reflux component, the present invention can replace the filling container without stopping the filling process. For special liquids that cannot be stopped during the filling process, the filling cannot be stopped directly after the filling is completed. Instead, the filling liquid will continue to flow back through the sealing reflux component to seal the outlet on the filling equipment. Thus, the filling can continue after the filling container is replaced. The liquid does not stop flowing during the entire container replacement process, resulting in a better filling effect.

[0019] Preferred embodiments of the present invention will be described with reference to the accompanying drawings to provide a full understanding of the invention. Embodiments of the present invention can be varied in many forms, and the scope of the invention is not limited to the embodiments described in the following detailed description. These embodiments are provided to provide a more complete explanation of the invention to those skilled in the art. Therefore, to further emphasize the clear description, the shapes of elements in the drawings may be shown enlarged. In the various drawings, the same reference numerals are assigned to the same parts. Detailed descriptions of well-known functions and structures that are deemed likely to obscure the essence of the invention will be omitted.

[0020] Please see Figure 1-4 This invention provides a liquid level monitoring and alarm device, comprising a discharge pipe 5, wherein the discharge pipe 5 has a plurality of annularly distributed discharge ports 11, a return cylinder 6 is fixedly connected to the bottom of the discharge pipe 5, a connecting cylinder 7 is slidably connected to the bottom of the return cylinder 6, a float 8 is fixedly connected to the bottom of the connecting cylinder 7, an alarm 9 is fixedly connected to the discharge pipe 5, an alarm switch 12 is fixedly connected to the surface of the return cylinder 6, and a toggle block 13 for actuating the alarm switch 12 is fixedly connected to the top of the connecting cylinder 7. A sealing return assembly is provided inside the discharge pipe 5. When the liquid level reaches the alarm height, if the liquid level continues to rise, the sealing return assembly controls the discharge ports to close and the liquid to return for transport.

[0021] When the above scheme is put into actual use, during monitoring, the connecting cylinder 7 is inserted into the filling container. The liquid to be filled flows into the container from the outlet 11 on the outside of the discharge pipe 5. The float 8 will float above the liquid surface, and as the liquid level rises, the connecting cylinder 7 will slide upward along the return cylinder 6. After the specified volume is reached, that is, when the connecting cylinder 7 rises to the side where the toggle block 13 activates the alarm switch 12, the alarm 9 will start to sound, alerting the staff. Then, filling continues, causing the connecting cylinder 7 to continue to rise. Then, the sealing return assembly inside the discharge pipe 5 will be activated, sealing the outlet 11 on the discharge pipe 5. Then the liquid inside the discharge pipe 5 is returned to the container. At this time, the operator can replace the new filling container below the connecting cylinder 7 to prepare for filling. After preparation, the operator puts the connecting cylinder 7 back into the container, and the sealing and reflux component will release the seal on the discharge port 11, allowing the liquid to continue filling. The purpose of this is to prevent the liquid from being stopped directly after filling for special liquids that cannot be stopped during the filling process. Instead, the liquid that will continue to be filled is returned by the sealing and reflux component to seal the discharge port 11 on the filling equipment. Thus, the filling can continue after the filling container is replaced. The liquid does not stop flowing during the entire process of changing the container.

[0022] As a further embodiment of the present invention, the sealing reflux assembly includes a connecting ring 19, which is rotatably disposed inside the discharge pipe 5. A fixing plate 21 is fixedly connected to the bottom of the discharge pipe 5. A plurality of rotating plates 22 arranged in a ring are rotatably connected to the fixing plate 21. A slide rail 23 is provided on one side of the fixing plate 21. A connecting shaft 16 that slides and engages with the slide rail 23 is fixedly connected to the bottom of the connecting ring 19. A protrusion is fixedly connected to the top of the rotating plate 22. A plurality of [unclear text - possibly related to a specific component or component] are fixedly connected to the inner wall of the connecting ring 19. The clamping blocks 20 are arranged in a ring, and the protrusions are arranged inside the clamping blocks 20. Several sealing plates 14 arranged in a ring and corresponding to the discharge port 11 are fixedly connected to the top of the connecting ring 19. A sliding groove 17 is opened on one side of the outer wall of the return cylinder 6. A slider for docking with the sliding groove 17 is fixedly connected to the top of the connecting cylinder 7. A limiting frame 18 capable of clamping the connecting shaft 16 is fixedly connected to the top of the connecting cylinder 7. A return pipe 3 is fixedly connected to one side of the return cylinder 6. An opening for the sliding of the return pipe 3 is opened on one side of the connecting cylinder 7.

[0023] When the above scheme is put into actual use, as the float 8 rises with the liquid level, the toggle block 13 on the connecting cylinder 7 triggers the alarm switch 12, which in turn triggers the alarm 9. At this time, the connecting cylinder 7 slides vertically upward along the chute 17. As the liquid level continues to rise, the connecting cylinder 7 begins to rotate and rise along the inclined section of the chute 17. At this time, the limit frame 18 engages with the connecting shaft 16. During the rotation of the connecting cylinder 7, the limit frame 18 clamps the connecting shaft 16 and rotates it together. The connecting shaft 16 drives the storage tank 1 to rotate together. The connecting ring 19 drives the rotating plate 22 to rotate through the clamping block 20. The rotating plate 22 rotates. The fixing plate 21 is opened, and the connecting ring 19 rotates to gradually seal the outlet 11. The fixing plate 21 opens and the outlet 11 closes, allowing the liquid inside the outlet pipe 5 to gradually flow to the return cylinder 6. Then, the liquid is returned through the return pipe 3 at one end of the return cylinder 6. The alarm 9 will remind the staff to get up and replace the container. After the container is replaced, the staff pulls the connecting cylinder 7 down to the initial position, which closes the fixing plate 21 and opens the outlet 11 for filling. This completes the filling cycle after the filling container is replaced.

[0024] As a further embodiment of the present invention, one end of the return pipe 3 is fixedly connected to a storage tank 1, the top of the storage tank 1 is fixedly connected to a connecting pipe 2, the top of the connecting pipe 2 is fixedly connected to a fixing frame 4, and one end of the fixing frame 4 is fixedly connected to the top of the discharge pipe 5.

[0025] When the above scheme is put into actual use, the returned liquid flows back into the storage tank 1 through the return pipe 3. Then, under the action of the suction pump, the liquid inside the storage tank 1 is drawn from the connecting pipe 2 to the fixed frame 4. After passing through the fixed frame 4, it is transported to the discharge pipe 5. One end of the storage tank 1 also has an inlet for connecting to the outside, so that liquid can be replenished into the storage tank 1 at any time.

[0026] As a further embodiment of the present invention, a flow limiting plate 10 is fixedly connected to the discharge pipe 5 outside the discharge port 11.

[0027] When the above solution is put into actual use, the discharge port 11 on the side wall of the discharge pipe 5 will splash outward under pressure when the liquid is sprayed out. The flow limiting plate 10 blocks the discharge port 11, so that the liquid sprayed out of the discharge port 11 can flow down along the surface of the flow limiting plate 10 and be more easily collected into the container.

[0028] As a further embodiment of the present invention, a sealing gasket is fixedly connected to the sealing plate 14.

[0029] When the above solution is put into actual use, after the sealing plate 14 is aligned with the discharge port 11 by means of the sealing gasket, the discharge port 11 can be sealed by the sealing gasket, thereby improving the sealing effect of the sealing plate 14 on the discharge port 11.

[0030] As a further embodiment of the present invention, magnetic blocks with opposite magnetic poles are embedded in both ends of the rotating plate 22.

[0031] When the above solution is put into actual use, after the rotating piece 22 rotates into a circle, several rotating pieces 22 are connected together in sequence. Under the action of the magnetic block, multiple rotating pieces 22 will be tightly attracted together, thus forming a closed ring on the fixed plate 21, thereby playing a sealing role.

[0032] As a further embodiment of the present invention, the connecting ring 19 can completely cover the top of the slide 23.

[0033] When the above solution is put into actual use, the connecting ring 19 blocks the slide 23, preventing liquid from seeping into the return cylinder 6 from the slide 23. Even if a small amount of liquid flows back into the return cylinder 6, it will not affect the overall filling process.

[0034] Working principle: The liquid to be filled is added into the storage tank 1. The liquid in the storage tank 1 is pumped into the fixed frame 4 through the suction pump on the connecting pipe 2. The liquid is then transported to the discharge pipe 5 through the fixed frame 4. The connecting cylinder 7 is inserted into the filling container. The liquid to be filled flows into the container from the discharge port 11 on the outside of the discharge pipe 5. The float 8 will float above the liquid surface. As the liquid level rises, the connecting cylinder 7 will slide upward along the return cylinder 6. After the filling reaches the specified volume, the connecting cylinder 7 rises to the side. The toggle block 13 toggles the alarm switch 12, and the alarm 9 will start to sound, reminding the staff to pay attention.

[0035] At this point, the connecting cylinder 7 slides vertically upward along the chute 17. As the liquid level continues to rise, the connecting cylinder 7 begins to rotate and rise along the inclined section of the chute 17. At this time, the limiting frame 18 aligns with the connecting shaft 16. During the rotation of the connecting cylinder 7, the limiting frame 18 clamps the connecting shaft 16 and rotates it together. The connecting shaft 16 drives the storage tank 1 to rotate together. The connecting ring 19 drives the rotating plate 22 to rotate through the clamping block 20. The rotation of the rotating plate 22 causes the fixing plate 21 to open. The rotation of the connecting ring 19 causes the sealing plate 14 to gradually seal the outlet 11. The opening of the fixing plate 21 and the closing of the outlet 11 allow the liquid inside the discharge pipe 5 to gradually flow to the return cylinder 6, and then through the return... The return pipe 3 at one end of the cylinder 6 returns the liquid back. The alarm 9 will remind the staff to get up and replace the container. After the container is replaced, the staff will pull the connecting cylinder 7 down to the initial position, which will close the fixing plate 21 and open the discharge port 11 for filling. This completes the filling cycle after the filling container is replaced. The returned liquid flows back into the storage tank 1 through the return pipe 3. Then, under the action of the suction pump, the liquid in the storage tank 1 is drawn from the connecting pipe 2 to the fixing frame 4. After passing through the fixing frame 4, it is transported to the discharge pipe 5. The storage tank 1 also has an external docking port at one end to facilitate the replenishment of liquid into the storage tank 1 at any time.

[0036] The embodiments of the present invention described above are merely examples, and those skilled in the art can make various modifications or derive other equivalent embodiments. Therefore, the present invention is not limited to the embodiments mentioned in the above detailed description. Thus, the true scope of protection of the present invention should be determined according to the technical concept of the appended claims. Furthermore, it should be understood that the present invention includes all variations, equivalents, and alternatives to the concept of the present invention as defined by the appended claims.
