Description

Technical Field

[0001] This utility model relates to the field of nano-aeration tube technology, and in particular to a pipeline flow detection device for nano-aeration tubes. Background Technology

[0002] Nano-aeration tubes are specialized oxygenation devices that achieve efficient water oxygenation by releasing microbubbles. They are primarily made of synthetic rubber or nanomaterials. During long-term operation, biofilms or particulate matter may clog the micropores, therefore flow monitoring is necessary to detect anomalies in real time. Uneven flow can lead to localized aeration failure, causing sludge accumulation or water hypoxia.

[0003] Currently, existing nano-aeration tubes often need to be submerged in the pool and soaked in the pool water when performing pipeline flow detection. This prolonged immersion can easily cause the flow detection sensor to malfunction, thus affecting the normal flow detection of the nano-aeration tube. Therefore, in order to improve the flow detection effect of nano-aeration tubes and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme for pipeline flow detection device and application method of nano-aeration tubes that differs from the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing nano-aeration pipes often need to be submerged in the pool and soaked in the pool water for a long time when performing pipeline flow detection, which can easily cause the flow detection sensor to malfunction and thus affect the normal flow detection of the nano-aeration pipe. Therefore, this invention proposes a pipeline flow detection device for nano-aeration pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe flow detection device for nano-aeration pipes includes a miniature gas flow sensor and a sealed housing for mounting the miniature gas flow sensor. Connecting pipes are fixedly inserted into both ends of the sealed housing, and the other ends of the two connecting pipes are fixedly connected to the miniature gas flow sensor. A sealing cover is provided on the top of the sealed housing. A first convex ring is integrally formed on the top of the sealed housing, and a second convex ring is integrally formed on the bottom of the sealing cover. Both the top of the sealed housing and the bottom of the sealing cover have slots, in which a second sealing ring is engaged. One end of the miniature gas flow sensor is electrically connected to a waterproof cable, and the other end of the waterproof cable passes through the sealing cover. Multiple anti-detachment plates are engaged on the outer wall of the waterproof cable. A groove is provided on the top of the sealing cover, and the anti-detachment plates are located within the groove, which is filled with a sealant layer.

[0007] Furthermore, the top of the sealing housing is fixedly connected with a plurality of second fixing bolts, the top ends of which protrude through the sealing cover plate.

[0008] Furthermore, a moisture-absorbing plate is adhered to the bottom of the sealing cover.

[0009] Furthermore, one end of one of the connecting pipes is connected to a connecting pipe via a flange, and the other end of the connecting pipe is connected to a control valve via a flange.

[0010] Furthermore, one end of the control valve is equipped with a clamp.

[0011] Furthermore, one end of the connecting pipe is fixedly connected with a plurality of first fixing bolts, and a first sealing ring is snapped into this end of the connecting pipe.

[0012] Furthermore, the first convex ring and the second convex ring respectively contact the two second sealing rings.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The first sealing ring seals the air inlet end of the connecting pipe, the connecting pipe and the pump body. Then, the first and second convex rings contact the two second sealing rings respectively to perform a double seal between the sealing shell and the sealing cover. Then, an epoxy resin layer or a polyurethane layer is used to form a sealing layer to seal the waterproof cable and the sealing cover, thereby better sealing the sealing shell and improving the sealing performance of the sealing shell so as not to affect the normal flow detection of the nano-aeration pipe.

[0015] 2. The clamp design facilitates the quick and easy installation of the nano-aeration pipe and control valve, and the operation is simple, convenient and fast. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A pipeline flow detection device for nano-aeration tubes includes a nano-aeration tube 20, a miniature gas flow sensor 3, and a sealed housing 1 for mounting the miniature gas flow sensor 3. The miniature gas flow sensor 3 is model FS4000. The sealed housing 1 provides airtight protection for the sensor to ensure its normal operation without being affected by the external environment.

[0024] Both ends of the sealed housing 1 are fixedly connected to the connecting pipe 2. The other end of the connecting pipe 2 is fixedly connected to the miniature gas flow sensor 3. Multiple first fixing bolts 4 are fixedly inserted into one end of the connecting pipe 2, and a first sealing ring 5 is snapped into this end of the connecting pipe 2.

[0025] The top of the sealing housing 1 is provided with a sealing cover plate 7. The top of the sealing housing 1 is integrally formed with a first protruding ring 6, and the bottom of the sealing cover plate 7 is integrally formed with a second protruding ring 8. Both the top of the sealing housing 1 and the bottom of the sealing cover plate 7 are provided with a slot, and a second sealing ring 9 is engaged in the slot.

[0026] The first sealing ring 5 and the second sealing ring 9 are made of nitrile rubber, fluororubber, and silicone rubber. The first convex ring 6 and the second convex ring 8 respectively contact the two second sealing rings 9. The first convex ring 6 and the second convex ring 8 respectively contact the two second sealing rings 9 to perform double sealing on the sealing housing 1 and the sealing cover plate 7.

[0027] One end of the miniature gas flow sensor 3 is electrically connected to a waterproof cable 11, and the other end of the waterproof cable 11 passes through the sealing cover 7. Multiple anti-detachment plates 12 are snapped onto the outer wall of the waterproof cable 11. The top of the sealing cover 7 is provided with a groove 13, and the anti-detachment plates 12 are located in the groove 13. The groove 13 is filled with a sealant layer 14, which is either an epoxy resin layer or a polyurethane layer. By using an epoxy resin layer or a polyurethane layer to form a sealant layer 14, the waterproof cable 11 and the sealing cover 7 are sealed, thereby preventing gaps between the waterproof cable 11 and the sealing cover 7, and thus better sealing the sealing housing 1.

[0028] Multiple second fixing bolts 15 are welded to the top of the sealing housing 1, and the top of the second fixing bolts 15 protrudes through the sealing cover plate 7.

[0029] A moisture-absorbing plate 10 is attached to the bottom of the sealing cover 7. The moisture-absorbing plate 10 is made of silicone material. The moisture-absorbing plate 10 absorbs the moisture inside the sealing housing 1 to avoid affecting the operation of the miniature gas flow sensor 3.

[0030] One end of one of the connecting pipes 2 is connected to a connecting pipe 17 via a flange, and the other end of the connecting pipe 17 is connected to a control valve 18 via a flange. One end of the control valve 18 is provided with a clamp 21, which can be connected to the nano aeration pipe 20 via the clamp 21, thereby quickly connecting the nano aeration pipe 20 and the control valve 18.

[0031] Gas is pumped into one of the connecting pipes 2, and then from the other connecting pipe 2 into the connecting pipe 17. It is then fed into the nano-aeration pipe 20 through the control valve 18. Finally, the gas is introduced into the pool water through the air holes of the nano-aeration pipe 20 to oxygenate the water.

[0032] In the prior art, the nano-aeration tube 20 is placed on top of the mounting frame 16, and multiple fixing rings 19 are welded to the top of the mounting frame 16. The nano-aeration tube 20 passes through the multiple fixing rings 19. The mounting frame 16 and the fixing rings 19 facilitate the limiting and support of the nano-aeration tube 20.

[0033] The working principle of this embodiment is as follows: In use, the sealed housing 1 of the micro gas flow sensor 3 is fixed to the bottom of the pool. Then, the air inlet of the pump body is connected to one of the connecting pipes 2 through the connecting pipe, and the connecting pipe 2 and the air inlet of the pump body are fixedly connected by the first fixing bolt 4. Then, one end of the nano aeration pipe 20 is fixedly connected to one end of the control valve 18 through the clamp 21. Then, the pump body is used to input gas into one of the connecting pipes 2. Then, the gas is input from the other connecting pipe 2 into the connecting pipe 17, and then into the nano aeration pipe 20 through the control valve 18. Then, the gas is input into the pool water through the air holes of the nano aeration pipe 20 for oxygenation. During this process, the micro gas flow sensor 3 detects the flow rate.

[0034] Then, the first sealing ring 5 seals the connection pipe 2 with the connecting pipe 17 and the air inlet of the pump body, thereby preventing water from entering the sealing housing 1 from this point. Next, the first convex ring 6 and the second convex ring 8 respectively contact the two second sealing rings 9 to perform a double seal between the sealing housing 1 and the sealing cover plate 7, thereby further preventing water from entering the sealing housing 1. Then, the sealing layer 14 formed by using epoxy resin adhesive layer or polyurethane adhesive layer seals the waterproof cable 11 and the sealing cover plate 7, thereby preventing gaps between the waterproof cable 11 and the sealing cover plate 7, and thus better sealing the sealing housing 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
