Description

Technical Field

[0001] This utility model relates to the field of anti-condensation water drying technology in hydropower stations, and in particular to a drying device based on anti-condensation water in hydropower stations. Background Technology

[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electrical energy generation device. It is a water conservancy project that realizes the conversion of water energy into electrical energy. The sustainability of electrical energy production requires that the utilization of water energy in hydropower stations be uninterrupted. Through the construction of the reservoir system of a hydropower station, the distribution of water resources in time and space can be artificially regulated and changed to achieve the sustainable utilization of water resources.

[0003] With the continuous improvement of information technology, communication technology and control technology, the level of equipment automation is becoming increasingly mature. From simple transmission mechanism control to intelligent integrated control, the requirements for the accuracy and stability of equipment are getting higher and higher. During the summer operation of hydropower stations, the temperature difference between the water in the cooling water pipes and the ambient temperature causes condensation, which is even more obvious in the underwater powerhouse behind the dam.

[0004] Condensate can flow into the equipment through the cable inlet, reducing its insulation performance and even causing malfunctions. In severe cases, it can lead to unplanned shutdowns of the unit, causing voltage fluctuations and instability in the power grid, directly threatening the safety of the equipment and personnel.

[0005] Therefore, it is necessary to provide a drying device based on the prevention of condensation in hydropower stations to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a drying device based on the prevention of condensation in hydropower stations, which solves the problem that condensation generated during the hydropower station production process due to temperature differences will enter the equipment through the cable inlet hole, thereby reducing the insulation performance of the equipment and affecting its normal operation.

[0007] To solve the above-mentioned technical problems, the present invention provides a drying device based on the prevention of condensation in hydropower stations, which includes: a differential pressure switch;

[0008] The inlet pipe is fixedly connected to the top of the differential pressure switch. The top of the inlet pipe has a through inlet. The inside of the inlet is equipped with a silicone shell, and the top of the silicone shell is equipped with a silicone top cover.

[0009] Multiple conduits are installed at the bottom of the inner wall of the silicone shell. The silicone shell has a filling chamber inside, which is filled with calcium oxide. Each conduit contains a cable, and the outer surface of each conduit has multiple adsorption holes.

[0010] The conduit is also made of silicone. The silicone shell, silicone top cover, and conduit itself are all made of liquid silicone. The liquid silicone covers and surrounds the conduit, making it soft and elastic, providing better waterproof and cushioning effects. It also has excellent high and low temperature resistance, allowing it to be used at extremely low temperatures below -60℃ and extremely high temperatures above 200℃ without deformation, aging, or hardening. Furthermore, it exhibits excellent resistance to climate change: it is not easily affected by moisture, is corrosion-resistant, oxidation-resistant, acid-resistant, and alkali-resistant, resulting in a longer service life. The calcium oxide filler maintains a moisture absorption capacity greater than 35% of its own weight, regardless of the ambient humidity. This gives it excellent drying and moisture-absorbing properties. It is natural, non-toxic, and harmless, and will not cause pollution or harm to the environment or human body. It absorbs moisture from the air and reacts with water to produce calcium hydroxide. This reaction is exothermic, releasing a large amount of heat while absorbing a large amount of water vapor.

[0011] Preferably, the silicone top cover has holes for the cable to pass through, and the outer surface of the conduit is provided with an annular filter screen;

[0012] The holes on the top of the silicone cap correspond to the positions of the conduit, and the annular filter screen is fitted onto the outer surface of the conduit to perform a filtering function.

[0013] Preferably, a filling tube is installed on the top of the silicone top cover, and a threaded cap is threadedly connected to the top end of the filling tube;

[0014] The filling tube allows calcium oxide filler to be injected into the interior of the filling chamber.

[0015] Preferably, mounting plates are fixedly connected to the opposite sides of the outer surface of the silicone top cover, and locking holes are provided on the opposite sides of the outer surface of the inlet tube.

[0016] Reference for mounting plate position Figure 6 .

[0017] Preferably, each of the mounting pieces is fixedly connected to a limiting piece at its bottom, and a fixing ring is fixedly connected to the opposite side of each of the two limiting pieces. A supporting spring is fixedly connected to the other end of each fixing ring.

[0018] The retaining ring has an opening in the middle through which the locking pin can pass.

[0019] Preferably, the other end of each support spring is fixedly connected to a fixed plate, one end of the fixed plate is fixedly connected to a movable ring, and the other end of the fixed plate is fixedly connected to a latch;

[0020] The movable ring and the limiting piece are in contact on one side. Pulling the movable ring can stretch the support spring, which can then pull the bolt out from inside the locking hole.

[0021] Compared with related technologies, the drying device based on the prevention of condensate from hydropower stations provided by this utility model has the following beneficial effects:

[0022] This invention provides a drying device for preventing condensate from entering the equipment via the cable. To prevent condensate from entering the equipment, an inlet pipe with a cable inlet is installed on top of the differential pressure switch. A silicone shell is then inserted into the inlet, with a silicone top cover positioned at the top of the inlet pipe. The silicone shell and top cover are made of liquid silicone, which is soft and elastic, providing better waterproofing and cushioning, and excellent resistance to high and low temperatures. Liquid silicone can be used at extremely low and high temperatures without deformation, aging, or hardening. Inside the silicone shell, multiple cable conduits, also made of silicone, are loosely packed to allow the cable to pass through. Between the conduits and the silicone shell is a filling chamber filled with calcium oxide filler to aid moisture absorption. This design utilizes the softness of the silicone to ensure a tight fit with the cable's outer surface, while the calcium oxide filler maintains a moisture absorption capacity greater than 35% of its own weight. This results in excellent drying and moisture absorption, improving equipment stability, reducing the probability of malfunction, and ensuring the safety of hydropower station equipment and personnel.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the drying device for preventing condensation in a hydropower station provided by this utility model; Figure 2 This utility model provides a structural schematic diagram of the inlet port; Figure 3 A schematic diagram of the conduit structure is provided for this utility model; Figure 4 This invention provides a schematic diagram of the adsorption pore structure. The drying device based on the anti-condensation water of a hydropower station includes: a differential pressure switch 1;

[0033] The inlet pipe 2 is fixedly connected to the top of the differential pressure switch 1. The top of the inlet pipe 2 has a through inlet port 7. The inside of the inlet port 7 is provided with a silicone shell 8. The top of the silicone shell 8 is equipped with a silicone top cover 6.

[0034] Multiple conduits 12 are installed at the bottom of the inner wall of the silicone shell 8. The silicone shell 8 has a filling chamber 10 inside, and the filling chamber 10 is filled with calcium oxide filler 9. Each conduit 12 has a cable 5 inside, and each conduit 12 has multiple adsorption holes 13 on its outer surface.

[0035] The conduit 12 is also made of silicone. The silicone outer shell 8, silicone top cover 6, and conduit 12 all use liquid silicone. The liquid silicone provides a soft and elastic feel, offering better waterproofing and cushioning, and excellent resistance to high and low temperatures. Liquid silicone can be used at extremely low temperatures below -60℃ and extremely high temperatures above 200℃ without deformation, aging, or hardening. It also exhibits excellent resistance to climate change: it is not easily affected by moisture, is corrosion-resistant, oxidation-resistant, acid-resistant, and alkali-resistant, resulting in a longer service life. The calcium oxide filler 9 maintains a concentration greater than its own weight regardless of the external humidity. With a moisture absorption capacity of 35%, it has excellent drying and moisture absorption effects. It is natural, non-toxic, and harmless, and will not cause pollution or harm to the environment or human body. It absorbs moisture from the air and reacts with water to produce calcium hydroxide. This reaction is an exothermic reaction, which releases a large amount of heat and absorbs a large amount of water vapor. When the ambient humidity drops, the released moisture will evaporate again, and the absorbed moisture will be released immediately and turn back into calcium oxide. The cable 5 runs through the bottom and top of the conduit 12. The adsorption hole 13 can adsorb moisture and allow it to react with calcium oxide. The adsorption hole 13 has a small diameter and the calcium oxide filler 9 will not leak.

[0036] The silicone top cover 6 has a hole for the cable 5 to pass through, and the outer surface of the conduit 12 is provided with an annular filter screen 11.

[0037] The holes on the top of the silicone top cover 6 correspond to the positions of the conduit 12. The annular filter 11 is fitted on the outer surface of the conduit 12 to filter impurities and prevent them from entering the interior of the filling chamber 10.

[0038] A filling tube 3 is installed on the top of the silicone top cover 6, and a threaded cap 4 is threadedly connected to the top end of the filling tube 3.

[0039] The filling tube 3 can inject calcium oxide filler 9 into the filling chamber 10, and the threaded cover 4 is equipped with a sealing gasket.

[0040] The working principle of the drying device based on the prevention of condensate from hydropower stations provided by this utility model is as follows:

[0041] A cable inlet tube 2 with a cable inlet 7 is installed on the top of the differential pressure switch 1. Then, the silicone shell 8 is inserted into the cable inlet 7, and the silicone top cover 6 is positioned at the top of the cable inlet tube 2. The silicone shell 8 and the silicone top cover 6 are made of liquid silicone, which is soft and elastic, has better waterproof and cushioning effects, and excellent high and low temperature resistance. Liquid silicone can be used at extremely low and extremely high temperatures without deformation, aging, or hardening. Inside the silicone shell 8, there are multiple cable conduits 12 that allow the cable 5 to pass through. The cable conduits 12 are also made of silicone. Between the cable conduits 12 and the silicone shell 8 is a filling chamber 10, which can be filled with calcium oxide filler 9 to assist in moisture absorption. In actual use, the calcium oxide filler 9 is first placed into the filling chamber 10, and the silicone shell 8 is inserted into the cable inlet 7. Then, the cable 5 is passed through the cable conduit 12 into the differential pressure switch 1. The silicone shell 8 can be used to block the cable inlet 7 on the cable inlet tube 2 to prevent condensate from entering the differential pressure switch 1.

[0042] Compared with related technologies, the drying device based on the prevention of condensate from hydropower stations provided by this utility model has the following beneficial effects:

[0043] To prevent condensate from entering the equipment along the cable, an inlet pipe 2 with an inlet port 7 is installed on the top of the differential pressure switch 1. Then, a silicone shell 8 is inserted into the inlet port 7, with the silicone top cover 6 positioned at the top of the inlet pipe 2. The silicone shell 8 and silicone top cover 6 are made of liquid silicone, which is soft and elastic, providing better waterproofing and cushioning, and excellent resistance to high and low temperatures. Liquid silicone can be used at extremely low and high temperatures without deformation, aging, or hardening. Inside the silicone shell 8, multiple conduits 12, also made of silicone, are loosely packed to allow the cable 5 to pass through. Between the conduits 12 and the silicone shell 8 is a filling chamber 10, which can be filled with calcium oxide filler 9 to aid in moisture absorption. This design utilizes the softness of silicone to ensure a tight fit with the outer surface of the cable 5. Simultaneously, the calcium oxide filler 9 maintains a moisture absorption capacity greater than 35% of its own weight, resulting in excellent drying and moisture absorption effects, improving equipment stability, reducing the probability of malfunction, and ensuring the safety of hydropower station equipment and personnel.

[0044] Second Embodiment

[0045] Please refer to the following: Figures 5-6 - Figure 7 ,picture Figure 5 A schematic diagram of the second embodiment of the drying device for preventing condensation in hydropower stations provided by this utility model. Figure 6 Provided for this utility model Figure 5 An enlarged view of point A shown; Figure 7This utility model provides a structural schematic diagram of a supporting spring. Based on the drying device for preventing condensation in a hydropower station provided in the first embodiment of this application, the second embodiment of this application proposes another drying device for preventing condensation in a hydropower station. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the difference between the drying device based on the anti-condensation water of a hydropower station provided in the second embodiment of this application is that the outer surface of the silicone top cover 6 is fixedly connected with the opposite side of the outer surface of the silicone top cover 6, and the outer surface of the inlet pipe 2 is provided with the opposite side of the outer surface of the inlet pipe 2.

[0047] Reference for the position of mounting plate 14 Figure 6 Hole 17 is for easy insertion of the bolt 21.

[0048] The bottom of each mounting plate 14 is fixedly connected to a limiting plate 15, and a fixing ring 20 is fixedly connected to the opposite side of each of the two limiting plates 15. A support spring 19 is fixedly connected to the other end of each fixing ring 20.

[0049] The fixing ring 20 has an opening in the middle through which the bolt 21 can pass, and the limiting piece 15 also has an opening through which the bolt 21 can pass.

[0050] The other end of each support spring 19 is fixedly connected to a fixed plate 18. One end of the fixed plate 18 is fixedly connected to a movable ring 16, and the other end of the fixed plate 18 is fixedly connected to a latch 21.

[0051] The movable ring 16 and the limiting piece 15 are in contact on one side. Pulling the movable ring 16 can stretch the support spring 19, thereby driving the bolt 21 to be pulled out from the inside of the locking hole 17. The support spring 19 provides the rebound force.

[0052] Compared with related technologies, the drying device based on the prevention of condensate from hydropower stations provided by this utility model has the following beneficial effects:

[0053] To increase the stability of the connection between the silicone shell 8, the silicone top cover 6, and the inlet pipe 2, a limiting piece 15 is installed on each of the opposite sides of the outer surface of the silicone top cover 6 via a mounting piece 14. When the silicone top cover 6 and the top of the inlet pipe 2 come into contact, the two limiting pieces 15 will contact the outer surface of the inlet pipe 2. Then, the latch 21 inside the movable ring 16 will be inserted into the locking hole 17 on the outer surface of the inlet pipe 2, thus completing the installation and reinforcement of the silicone top cover 6 on the inlet pipe 2. When it is necessary to remove the silicone top cover 6, simply pull the movable ring 16 to raise the support spring 19, which will allow the latch 21 to be pulled out from the inside of the locking hole 17. Then, the silicone top cover 6 can be easily pulled upward to remove the silicone shell 8. This structure increases the stability of the connection between the silicone top cover 6 and the inlet pipe 2.
