Description

Technical Field

[0001] This invention relates to the field of wind power hydrogen production technology, specifically a cooling tower heat dissipation device. Background Technology

[0002] Wind power-to-hydrogen technology utilizes wind energy to produce hydrogen, aiming to promote energy transition and reduce carbon emissions. It primarily involves two key technologies: electro-hydrogen conversion and hydrogen transportation. The principle involves using electricity generated by wind power to electrolyze water, producing hydrogen and oxygen. During this process, a large amount of heat is generated. If this heat is not dissipated in time, it can affect the normal operation of the equipment and may even pose safety hazards. The main function of a cooling tower in hydrogen production is heat dissipation and cooling, ensuring stable operation of the hydrogen production equipment and improving energy conversion efficiency. The cooling tower's heat dissipation device is a core component. Closed-circuit cooling towers are a type of cooling tower, and their heat dissipation devices are highly efficient and environmentally friendly cooling equipment. Their core lies in achieving a fully enclosed internal circulation of circulating water and dissipating heat to the outside atmosphere through a specific heat dissipation mechanism. The working principle of a closed-circuit cooling tower's heat dissipation device is mainly based on the following systems:

[0003] Internal circulation system: The cooled circulating medium flows through a closed tube bundle, completely isolated from the outside environment and without contact. In this way, the heat energy of the circulating medium can be effectively transferred to the outer wall of the tube bundle as it flows inside.

[0004] External circulation system (spray system): The water is evenly sprayed onto the condenser coil by a low-head, high-flow spray pump. The water forms a thin film on the outside of the tube bundle, covering the tube wall. After being heated by the high-temperature medium inside the tube, the water film absorbs heat energy, which is converted into latent heat of vaporization and evaporates into water vapor, thereby carrying away the heat energy.

[0005] Air exchange system: External air enters through the air inlet filter and then enters from the bottom of the heat exchange tube bundle. It passes over the tube bundle at high speed and exchanges heat with the tube wall through convection. At the same time, the high enthalpy gas carrying water vapor is drawn out of the tower by the axial flow fan, thus achieving the purpose of transferring heat energy to the outside of the tower.

[0006] However, when existing cooling tower heat dissipation devices are in use, external impurities can easily enter the interior of the closed cooling tower through the fan's protective screen and air duct. Moreover, when the fan is working, impurities are easily blown onto the protective screen, thus affecting the heat dissipation effect. At the same time, impurities are easily attached to the air inlet filter, affecting the air intake effect. Furthermore, when the outside air temperature is high, it will also affect the heat dissipation effect. Summary of the Invention

[0066] Compared with the prior art, the beneficial effects of the present invention are:

[0067] (1) This type of cooling tower heat dissipation device, by setting a first moving mechanism and a first lifting mechanism, etc., when the cooling device is not working, the first moving cover can seal the air duct, and the filter plate can block impurities falling into the air duct, preventing impurities from entering the interior of the closed cooling tower. When the cooling device is working, the spray pump is started, so that the cooling water circulates and enters the closed cooling tower through the liquid supply pipe, and then sprays onto the condenser coil from the top through the spray pipe. At the same time, when the cooling water enters the liquid supply pipe, under the action of water pressure, it can push the moving rod and the first moving block to move away from the fixed pipe. At the same time, the second elastic element is compressed. Meanwhile, when the first moving block moves, it can drive the push rod along the inclined groove through the support block. The sliding mechanism moves the first movable cover outward from the fixed cover via the connecting plate and the first slider. Simultaneously, the first elastic element is compressed, opening the air duct and starting the fan to ensure its normal operation. This allows the hot air inside the closed cooling tower to be discharged through the air duct. After the first movable cover moves out of the fixed cover, the first lifting mechanism moves the filter plate synchronously. When the second connecting block slides along the top of the first inclined plate, it pushes the second connecting block and the filter plate upward to above the first movable cover. At the same time, the third elastic element is compressed, allowing impurities on the filter plate to slide downward for discharge and collection, preventing them from being blown onto the protective mesh cover with the hot air and ensuring effective heat dissipation.

[0068] (2) This type of cooling tower heat dissipation device, by setting up a squeezing mechanism, allows rainwater to enter the first movable hood after being filtered by the filter plate when the cooling device is not working or when it is working. Then, it enters the water tank through the water collection pipe for collection. When the cooling device is working, the cooling water enters the working box and impacts the surface of the fan blades, causing the fan blades to rotate along the shaft. At the same time, when the shaft rotates, it can drive the cam to rotate through the connecting shaft. When the temperature sensor detects that the air temperature discharged through the air duct is high, it energizes the electromagnet. After the electromagnet is energized, it can attract the iron block, causing the second movable block and the second inclined plate to move towards the third slider. At the same time, the fifth elastic element is compressed. Under the guidance of the second inclined plate, the second movable block can move to the bottom of the cam. When the tip of the cam abuts against the top of the second movable block, it can push the second movable block and the movable plate downward. At the same time, the fourth elastic element is compressed. When the tip of the cam passes the top of the second movable block, the second movable block and the movable plate can... Under the action of the fourth elastic element, it can move upward and reset. By repeating this process, the moving plate can move up and down, and the second moving cover can be moved up and down through the first L-shaped block. When the second moving block moves, the push plate can be moved synchronously through the second L-shaped block, the fifth connecting block and the fourth slider, so that the push pin can gradually slide down along the inclined plane and disengage. At this time, the squeezing plate can gradually move down and squeeze the rainwater collected in the water tank. At the same time, the first one-way valve closes and the second one-way valve opens. At this time, the rainwater in the water tank can be squeezed and enter the second moving cover through the water supply pipe, and be absorbed by the sponge block. Thus, when the second moving cover moves up and down, it can coat the surface of the air inlet filter. When the second moving cover moves, it can drive the brush bristles to move synchronously through the mounting plate, which can not only clean the surface of the air inlet filter, but also make the coated rainwater more even. The coated rainwater can evaporate and absorb heat when the air is inlet, thereby improving the heat dissipation effect. Attached Figure Description

[0082] Please see Figures 1-11 This invention provides a cooling tower heat dissipation device, comprising a wind duct 11 installed at the top of a closed-circuit cooling tower 1, a protective mesh cover 12 and a fan 13 installed inside the wind duct 11, two air inlet filters 14 installed on the side wall of the closed-circuit cooling tower 1, a spray pump 15 installed on the side wall of the closed-circuit cooling tower 1, and a liquid supply pipe 25 installed between the spray pump 15 and the closed-circuit cooling tower 1. The closed-circuit cooling tower 1 also includes a spray module and a condenser coil module, etc., which are well-known technologies in this field and will not be elaborated upon here. The cooling tower heat dissipation device further includes:

[0083] The fixed cover 16 is fixedly inserted into the side wall of the air duct 11 and is connected to the air duct 11.

[0085] The first lifting mechanism is disposed on the side wall of the first movable cover 17, and a filter plate 18 inclined downward is connected to the first lifting mechanism. The first lifting mechanism is used to drive the filter plate 18 to move up and down within the first movable cover 17.

[0086] The second lifting mechanism is installed on the side wall of the closed cooling tower 1, and two second movable covers 21 are connected to the second lifting mechanism. The second lifting mechanism is used to lift and move the second movable covers 21.

[0087] Sponge blocks 23 are inserted into each of the second movable covers 21 and fixed to the inner wall of the second movable cover 21 by perforated plates 22.

[0088] Water tank 19 is located below closed cooling tower 1 and is connected to first movable cover 17 via water collection pipe 20. Water tank 19 is also connected to second movable cover 21 via water supply pipe 24. A first one-way valve is installed in water collection pipe 20, and the conduction direction of the first one-way valve is from first movable cover 17 to water tank 19. A second one-way valve is installed in water supply pipe 24, and the conduction direction of the second one-way valve is from water tank 19 to second movable cover 21.

[0089] The squeezing mechanism, located inside the water tank 19, is used to squeeze the rainwater in the tank 19. When the cooling device is not working, it can seal the air duct 11 and block incoming impurities. When the cooling device is working, it can open the air duct 11 to ensure normal air discharge and remove blocked impurities, preventing them from being blown onto the protective mesh cover 12 with the hot air, thus ensuring effective heat dissipation. It can also collect rainwater and apply it to the surface of the air inlet filter 14, cleaning the surface of the filter 14.

[0090] Please see Figure 6 and Figure 8 The first moving mechanism includes:

[0091] Two first T-shaped guide rods 203 are fixed to the side wall of the fixed cover 16 by the first connecting block 201.

[0092] The first slider 202 is sleeved on the side wall of the two first T-shaped guide rods 203 and fixed to the side wall of the first movable cover 17.

[0093] Two first elastic elements 204 are sleeved on the side walls of two first T-shaped guide rods 203, and the first elastic elements 204 are located between the ends of the first slider 202 and the first T-shaped guide rods 203. The first elastic elements 204 can be springs, and the two ends of the first elastic elements 204 are fixed to the ends of the first slider 202 and the first T-shaped guide rods 203, respectively.

[0094] The connecting plate 205 is fixed to the bottom of the first slider 202, and the top of the connecting plate 205 is provided with a sloping groove 206.

[0095] The second moving mechanism is disposed on the side wall of the liquid supply pipe 25, and the first moving block 207 is connected to the second moving mechanism. The second moving mechanism is used to move the first moving block 207.

[0096] The push rod 213 is inserted into the inclined groove 206 and fixed to the side wall of the first moving block 207 by the support block 208. The second moving mechanism drives the first moving block 207 to move away from the liquid supply pipe 25. When the first moving block 207 moves, the push rod 213 can slide along the inclined groove 206 through the support block 208. Thus, the first moving cover 17 is moved out of the fixed cover 16 through the connecting plate 205 and the first slider 202. At the same time, the first elastic element 204 is compressed, thereby opening the air duct 11.

[0097] Please see Figure 6 The second moving mechanism includes:

[0098] Two second T-shaped guide rods 801 are fixed to the side wall of the liquid supply pipe 25 and are installed through the side wall of the first moving block 207.

[0099] Two second elastic elements 802 are sleeved on the side walls of two second T-shaped guide rods 801, and the second elastic elements 802 are located between the first moving block 207 and the end of the second T-shaped guide rod 801.

[0100] The fixing tube 803 is fixedly inserted into the side wall of the liquid supply tube 25.

[0101] The movable rod 804 is inserted into the fixed pipe 803, and its end away from the fixed pipe 803 is fixed to the first movable block 207. When the cooling device is working, the spray pump 15 is started, so that the cooling water circulates and enters the closed cooling tower 1 through the liquid supply pipe 25. Then, it is sprayed from the top onto the condenser coil through the spray pipe. At the same time, when the cooling water enters the liquid supply pipe 25, under the action of water pressure, it can push the movable rod 804 and the first movable block 207 to move away from the fixed pipe 803. At the same time, the second elastic element 802 is compressed.

[0102] Please see Figure 8 The first lifting mechanism includes:

[0103] A strip-shaped opening 301 is formed on the side wall of the first movable cover 17.

[0104] The second connecting block 302 is inserted into the strip opening 301 and fixed to the side wall of the filter plate 18.

[0105] Two third T-shaped guide rods 303 are fixed to the top of the second connecting block 302.

[0108] The first inclined plate 307 is fixed above the closed cooling tower 1 by the third connecting block 306. After the first movable cover 17 is moved out of the fixed cover 16, when the first movable cover 17 moves, it can drive the filter plate 18 to move synchronously through the first lifting mechanism. When the second connecting block 302 slides along the top of the first inclined plate 307, it can push the second connecting block 302 and the filter plate 18 to move upward and move above the first movable cover 17. At the same time, the third elastic member 305 is compressed. At this time, the impurities on the filter plate 18 can slide down and be discharged and collected, avoiding being blown onto the protective net cover 12 with the hot air, thus ensuring the heat dissipation effect.

[0109] Please see Figure 6 , Figure 7 and Figure 11 The second lifting mechanism includes:

[0110] The movable plate 401 is slidably connected to the side wall of the closed cooling tower 1 and fixed to the side wall of the second movable cover 21 by two first L-shaped blocks 402.

The fourth elastic elements 405 can be springs, and the two ends of the fourth elastic elements 405 are respectively fixed to the ends of the fourth connecting block 404 and the fourth T-shaped guide rod 403.

[0114] The first pushing mechanism, located on the side wall of the liquid supply pipe 25, is used to push the moving plate 401 to move up and down. Under the action of the first pushing mechanism and the fourth elastic element 405, the moving plate 401 can move up and down reciprocally. At the same time, the rainwater in the water tank 19 can enter the second moving cover 21 through the water supply pipe 24 under the action of the squeezing mechanism and be absorbed by the sponge block 23. Thus, when the second moving cover 21 moves up and down reciprocally, the rainwater can be coated on the surface of the air inlet filter 14. The coated rainwater can evaporate and absorb heat when the air is inlet, thereby improving the heat dissipation effect.

[0115] Please see Figure 7 and Figure 11 The primary driving forces include:

[0116] The working box 501 is fixedly inserted into the side wall of the liquid supply pipe 25 and connected to it.

[0118] Cam 505 is fixed to one end of rotating shaft 502 near closed cooling tower 1 via connecting shaft 504.

[0119] The third moving mechanism is located on the side wall of the moving plate 401, and the second moving block 506 is connected to the third moving mechanism. The third moving mechanism is used to move the second moving block 506.

[0120] The second inclined plate 507 is fixed to the side of the second moving block 506 near the cam 505. When the temperature sensor 706 detects that the air temperature discharged through the air duct 11 is high, the third moving mechanism drives the second moving block 506 and the second inclined plate 507 to move. Under the guidance of the second inclined plate 507, the second moving block 506 can move to below the cam 505. When the tip of the cam 505 abuts against the top of the second moving block 506, it can push the second moving block 506 and the moving plate 401 to move downward. At the same time, the fourth elastic member 405 is compressed. When the tip of the cam 505 passes the top of the second moving block 506, the second moving block 506 and the moving plate 401 can move upward and reset under the action of the fourth elastic member 405. By repeating this process, the moving plate 401 can move up and down, and the first L-shaped block 402 drives the second moving cover 21 to move up and down.

[0121] Please see Figure 2 , Figure 6 , Figure 7 and Figure 11 The extrusion mechanism includes:

[0122] The extrusion plate 601 slides within the water tank 19.

[0123] A push plate 604 slides above the water tank 19, and the push plate 604 includes an inclined surface 605.

[0124] Push pin 603 is located above water tank 19 and is fixed to the top of extrusion plate 601 by connecting rod 602, so that push pin 603 can slide on inclined surface 605.

[0125] The second pushing mechanism is located on the side wall of the pushing plate 604 and is used to push the pushing plate 604 to move. When the second moving block 506 moves, the pushing mechanism can drive the pushing plate 604 to move synchronously, so that the pushing pin 603 can gradually slide down along the inclined surface 605 and disengage. At this time, the squeezing plate 601 can gradually move down and squeeze the rainwater collected in the water tank 19.

[0126] Please see Figure 5 and Figure 10 In this embodiment, the cooling tower heat dissipation device further includes:

[0127] A cleaning mechanism is installed at the top and bottom of the second movable cover 21 for cleaning the air inlet filter 14.

[0128] Cleaning services include:

[0129] Two mounting plates 901 are fixed to the top and bottom of the second movable cover 21, and multiple bristles 902 are fixedly connected to the side wall of each mounting plate 901. When the second movable cover 21 moves, the mounting plates 901 can drive the bristles 902 to move synchronously, which can not only clean the surface of the air inlet filter 14, but also make the rainwater after application more even.

[0130] Please see Figure 1 and Figure 11 The third mobile mechanism includes:

[0131] Two fifth T-shaped guide rods 702 are fixed to the side wall of the second moving block 506.

[0132] The third slider 701 is sleeved on the side wall of the two fifth T-shaped guide rods 702 and fixed to the side wall of the second moving plate 401.

[0133] Two fifth elastic elements 703 are sleeved on the side walls of the two fifth T-shaped guide rods 702, and the fifth elastic elements 703 are located between the second moving block 506 and the third slider 701. The fifth elastic elements 703 can be springs, and the two ends of the fifth elastic elements 703 are fixed to the second moving block 506 and the third slider 701 respectively.

[0134] Electromagnet 704 is fixed to the side wall of the third slider 701.

[0135] Iron block 705 is fixed to the side wall of the second moving block 506 and is arranged opposite to electromagnet 704.

[0136] Temperature sensor 706 is fixedly inserted into the side wall of air duct 11 and electrically connected to electromagnet 704. When temperature sensor 706 detects that the air temperature discharged through air duct 11 is high, it energizes electromagnet 704. After being energized, electromagnet 704 can attract iron block 705, causing second moving block 506 and second inclined plate 507 to move closer to third slider 701. At the same time, fifth elastic element 703 is compressed. Under the guidance of second inclined plate 507, second moving block 506 can move to below cam 505.

[0137] Please see Figure 7 and Figure 11 The second driving body includes:

[0138] The fourth slider 1004 slides on the side wall of the push plate 604 through the slide groove 1001.

[0139] The fifth connecting block 1002 is fixed to the side wall of the fourth slider 1004 and to the side wall of the second moving block 506 via the second L-shaped block 1003. When the second moving block 506 moves, the push plate 604 can be driven to move synchronously via the second L-shaped block 1003, the fifth connecting block 1002 and the fourth slider 1004, so that the push pin 603 can gradually slide down along the inclined plane 605 and disengage.

[0140] Working principle: When the cooling device is not in operation, the first movable cover 17 can seal the air duct 11, and the filter plate 18 can block impurities falling into the air duct 11, preventing impurities from entering the interior of the closed cooling tower 1. When the cooling device is in operation, the spray pump 15 is started, so that the cooling water circulates and enters the closed cooling tower 1 through the liquid supply pipe 25, and then sprays onto the condenser coil from the top through the spray pipe. At the same time, when the cooling water enters the liquid supply pipe 25, under the action of water pressure, it can push the movable rod 804 and the first movable block 207 to move away from the fixed pipe 803. At the same time, the second elastic element 802 is compressed. Meanwhile, when the first movable block 207 moves, it can drive the push rod 213 to slide along the inclined groove 206 through the support block 208, thereby connecting the connecting plate 205 and the first A slider 202 moves the first movable cover 17 out of the fixed cover 16. At the same time, the first elastic element 204 is compressed, thereby opening the air duct 11 and starting the fan 13 to ensure normal operation. The fan 13 can discharge the hot air in the closed cooling tower 1 through the air duct 11. After the first movable cover 17 moves out of the fixed cover 16, the first lifting mechanism can drive the filter plate 18 to move synchronously. When the second connecting block 302 slides along the top of the first inclined plate 307, it can push the second connecting block 302 and the filter plate 18 to move upward and above the first movable cover 17. At the same time, the third elastic element 305 is compressed. At this time, the impurities on the filter plate 18 can slide down and be discharged and collected, preventing them from being blown onto the protective net cover 12 with the hot air, thus ensuring the heat dissipation effect.

[0141] When the cooling device is not in operation or is in operation, rainwater can enter the first movable cover 17 after being filtered by the filter plate 18. Then, it enters the water tank 19 through the water collection pipe 20 for collection. When the cooling device is in operation, cooling water enters the working box 501 and impacts the surface of the fan blade 503, causing the fan blade 503 to rotate along the rotating shaft 502. At the same time, when the rotating shaft 502 rotates, it can drive the cam 505 to rotate through the connecting shaft 504. When the temperature sensor 706 detects that the air temperature discharged through the air duct 11 is high, it energizes the electromagnet 704. After the electromagnet 704 is energized, it can attract the iron block 705, causing the second movable block 506 and the second inclined plate 507 to move closer to the third slider 701. At the same time, the fifth elastic element 703 is compressed. Under the guidance of the second inclined plate 507, the second movable block 506 can move to the bottom of the cam 505.

[0142] When the tip of the cam 505 abuts against the top of the second moving block 506, it can push the second moving block 506 and the moving plate 401 downward. At the same time, the fourth elastic element 405 is compressed. When the tip of the cam 505 passes the top of the second moving block 506, the second moving block 506 and the moving plate 401 can move upward and reset under the action of the fourth elastic element 405. This reciprocating motion allows the moving plate 401 to move up and down, and drives the second moving cover 21 to move up and down via the first L-shaped block 402. Furthermore, when the second moving block 506 moves, it can drive the push plate 604 to move synchronously via the second L-shaped block 1003, the fifth connecting block 1002, and the fourth slider 1004, so that the push pin 603 can move along the inclined plane. As surface 605 gradually slides downwards and detaches, the extrusion plate 601 can gradually move downwards and extrude the rainwater collected in the water tank 19. At the same time, the first one-way valve closes and the second one-way valve opens. The rainwater in the water tank 19 can be extruded and enter the second movable cover 21 through the water supply pipe 24, where it is absorbed by the sponge block 23. As the second movable cover 21 moves up and down, it can spread the rainwater onto the surface of the air intake filter 14. When the second movable cover 21 moves, the bristles 902 can move synchronously via the mounting plate 901. This not only cleans the surface of the air intake filter 14 but also makes the spread rainwater more even. The spread rainwater can evaporate and absorb heat during air intake, thereby improving the heat dissipation effect.

[0143] When the temperature sensor 706 detects that the temperature of the discharged air is within the normal range, the electromagnet 704 can be de-energized. At this time, the second moving block 506 and the second inclined plate 507 can move and reset under the action of the fifth elastic element 703, and the cam 506 is disengaged from the second moving block 505 to avoid wasting power. At the same time, the push plate 604 is moved by the second L-shaped block 1003, the fifth connecting block 1002 and the fourth slider 1004, so that the push pin 603 can slide along the inclined surface 605 to the top of the push plate 604, thereby driving the squeezing plate 601 to move upward through the connecting rod 602. At this time, the squeezing operation of rainwater is no longer performed.
