Description
Technical Field
[0001] The invention belongs to the technical field of cooling systems, and in particular relates to a ship assembled cooling system. Background Art
[0002] The ship assembled cooling system is a system that combines multiple functional modules to meet the cooling needs of various equipment on the ship. It is usually composed of multiple sub-modules, such as refrigeration module, liquid supply module, liquid replenishment module, monitoring module, etc. The modules work together to achieve the cooling function.
[0003] Compared with traditional single cooling systems, the modular design of the ship's assembled cooling system allows the ship to be flexibly configured according to different needs, and the system can be quickly maintained and replaced when performing missions at sea. It has higher adjustability and maintainability, and is widely used in military, commercial, scientific research and other fields of ships. Especially in situations where space is limited, equipment is diverse, and the working environment is complex, it can effectively ensure the operational stability of the ship.
[0004] However, the existing ship assembly cooling system usually has the following technical problems during use: After the cooling system has been used for a long time, it is necessary to discharge the contaminated refrigerant in the system and refill the system with refrigerant to ensure that the total amount of refrigerant remains unchanged. In this process, air is likely to enter the cooling system, which not only causes the air to occupy part of the space in the condenser, hindering the full contact between the refrigerant and the condenser wall, and reducing the heat transfer efficiency, but the presence of air will also increase the pressure in the condenser and increase the condensation temperature of the refrigerant. When the condensation temperature increases, the cooling capacity of the cooling system will decrease, and the compressor will need to consume more energy to maintain the refrigeration cycle, increasing unnecessary energy consumption.

[0015] Compared with the existing technology, the advantages of this ship assembly cooling system are: 1. The present invention provides an exhaust mechanism, which can drive the transfer tank to shake through the shaking of the ship during operation, so that the refrigerant can make the air inside the transfer tank float upward when flowing through the inside of the transfer tank. Then, the air pressure in the space above the refrigerant in the transfer tank is detected by the pressure sensor. After the air is removed from the refrigerant, the automatic exhaust valve is opened in time to discharge the air, thereby avoiding the mixing of air into the refrigeration system after the refrigerant is discharged and filled, thereby improving the heat transfer efficiency and reducing unnecessary energy consumption.
[0016] 2. The present invention provides a stirring mechanism. During the operation of the ship, the shaking of the transfer tank will also cause the driving water in the control chamber to shake continuously. The fluctuation of the driving water drives the float plate to move up and down reciprocatingly in the control chamber, thereby driving multiple groups of stirring rods to move in a circular motion, stirring the refrigerant flowing through the transfer chamber. The stirring causes turbulence in the refrigerant, breaking the laminar boundary layer on the bubble surface, reducing the viscous resistance between the bubbles and the refrigerant, and thus improving the discharge effect of the air in the refrigerant.
[0017] 3. The present invention sets an auxiliary mechanism. In the process of continuous shaking of the driving water in the control chamber, the driving assembly can drive the two fan-shaped driving blocks to periodically move away from each other, thereby disturbing the driving water and increasing the amplitude and frequency of the driving water fluctuations. This ensures that the energy generated when the ship shakes is sufficient to drive the stirring mechanism to work, thereby ensuring the stirring effect of the stirring mechanism on the refrigerant and further ensuring the discharge effect of the air in the refrigerant.
[0018] 4. The present invention sets an adaptive compensation mechanism. In the process of the ship shaking causing the driving water to fluctuate, the liquid level sensor can detect the fluctuation amplitude and frequency of the driving water in the control chamber, and transmit the detected data to the PLC controller through an electrical signal. The power of the DC motor is further controlled by the PLC controller. When the ship shakes less, the movement frequency of the two fan-shaped driving blocks is controlled to be faster to enhance the fluctuation of the driving water and ensure the operation of the stirring mechanism. When the ship shakes more, the movement frequency of the two fan-shaped driving blocks is controlled to be appropriately reduced to avoid over-driving and reduce energy consumption.
[0019] 5. The present invention sets a flow control mechanism. In the process of the ship shaking and driving the water wave, the shaking of the ship can be fed back through the moving frequency of the two driving blocks. The circulation rate of the refrigerant is further adjusted according to the shaking of the ship. When the shaking amplitude of the ship is small, the opening of the electronic throttle valve is controlled to increase, thereby increasing the circulation rate of the refrigerant when the ship is relatively stable, so as to improve the cooling effect of the refrigeration system. When the shaking amplitude of the ship is large, the opening of the electronic throttle valve is controlled to decrease. When the ship shakes more, the circulation rate of the refrigerant is reduced to avoid the mixing of air. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0023] Example: Refer to Figures 1 to 7 , a ship assembled cooling system, comprising: A storage tank 1, a transfer tank 2 and a heat exchange device 3, wherein a first infusion hose 21 is fixedly connected between the transfer tank 2 and the storage tank 1, and a second infusion hose 22 is fixedly connected between the transfer tank 2 and the heat exchange device 3; Specifically, one side of the storage tank 1 is connected to a compressor, and a circulating pump is provided between the heat exchange device 3 and the storage tank 1. In actual use, the circulating pump can drive the refrigerant to circulate in the compressor, the storage tank 1, the first infusion hose 21, the transfer tank 2, the second infusion hose 22 and the heat exchange device 3 to absorb the heat generated by the ship equipment (such as the engine, the generator, the equipment electrical system, etc.). This is an existing mature technology and will not be elaborated on here.
[0024] The exhaust mechanism 4 is used to exhaust the air in the refrigerant flowing through the transfer tank 2. The exhaust mechanism 4 includes a fixed frame 41 fixedly mounted on the ship body. The transfer tank 2 is arranged in the fixed frame 41, and a plurality of first springs 42 distributed in a circumferential array are arranged between the transfer tank 2 and the inner side wall of the fixed frame 41. A transfer chamber 43 is opened inside the transfer tank 2. An exhaust pipe 44 is fixedly connected to the upper end of the transfer tank 2. An automatic exhaust valve 45 is arranged in the exhaust pipe 44. A pressure sensor 46 is fixedly connected to the inner top wall of the transfer chamber 43. A PLC controller 47 is arranged on the outer wall of the transfer tank 2. The PLC controller 47 controls the opening and closing of the automatic exhaust valve 45 according to the pressure data fed back by the pressure sensor 46. Specifically, the opening pressure of the automatic exhaust valve 45 is 0.2MPa, and the closing pressure is 0.15MPa. When the pressure sensor 46 detects that the pressure is greater than 0.2MPa for 10 seconds, the automatic exhaust valve 45 is opened; after the pressure drops to 0.15MPa, it continues to be opened for 5 seconds to ensure exhaustion.
[0025] In view of the problem in the prior art that air is easily introduced into the cooling system during the process of discharging and filling the refrigerant, the present invention provides an exhaust mechanism 4. Since the ship is prone to shaking during operation, the shaking of the ship can drive the transfer tank 2 to shake, so that the transfer tank 2 can move on the bottom wall of the fixed frame 41, so that the refrigerant flowing through the transfer tank 2 shakes with the transfer tank 2. Through this shaking, the refrigerant can make the air inside the transfer tank 2 float upward when flowing through the inside of the transfer tank 2, and further be discharged to the space above the refrigerant in the transfer tank 2 to remove the air in the refrigerant. Subsequently, the air pressure in the space above the refrigerant in the transfer tank 2 is detected by the pressure sensor 46. After the air is removed from the refrigerant, the automatic exhaust valve 45 is opened in time to discharge the air to prevent the air from being mixed into the refrigerant again. This can prevent the mixing of air into the refrigeration system after the refrigerant is discharged and filled, thereby improving the heat transfer efficiency and reducing unnecessary energy consumption.
[0026] The stirring mechanism 5 is used to utilize the energy generated when the ship is rocking to improve the effect of discharging air in the refrigerant. The stirring mechanism 5 includes a control chamber 51 opened inside the transfer tank 2 and located below the transfer chamber 43. A floating plate 52 is slidably connected to the inner wall of the control chamber 51 in the vertical direction. The control chamber 51 is filled with driving liquid. A connecting rod 53 is hinged on the floating plate 52 through a hinge seat. A rotating rod 54 is rotatably connected to the inner bottom wall of the transfer chamber 43. A plurality of stirring rods 55 distributed in a linear array are fixedly connected to the rod body of the rotating rod 54. A transmission rod 56 is rotatably connected to the position between the transfer chamber 43 and the control chamber 51. A bevel gear set 57 is provided at the end where the transmission rod 56 and the rotating rod 54 are close to each other. A turntable 58 is fixedly connected to the end of the transmission rod 56 away from the rotating rod 54. A pin 59 is fixedly connected to the turntable 58. A sleeve 510 is rotatably sleeved on the pin 59. The end of the connecting rod 53 away from the floating plate 52 is fixedly connected to the sleeve 510.
[0027] It is worth mentioning that, by setting a stirring mechanism 5, during the operation of the ship, the shaking of the transfer tank 2 will also cause the driving water in the control chamber 51 to shake continuously, and the fluctuation of the driving water will drive the float plate 52 to move up and down reciprocatingly in the control chamber 51, thereby driving the turntable 58 to rotate through the connecting rod 53, the sleeve 510 and the pin 59, so that the transmission rod 56 rotates, and further drives the rotating rod 54 to rotate under the action of the bevel gear set 57, driving the multiple groups of stirring rods 55 to perform circular motion, and stirring the refrigerant flowing through the transfer chamber 43. The refrigerant is turbulent through stirring, breaking the laminar boundary layer on the bubble surface, reducing the viscous resistance between the bubbles and the refrigerant, and thus improving the discharge effect of the air in the refrigerant.
[0028] The auxiliary mechanism 6 is used to ensure that the energy generated when the ship shakes is sufficient to drive the stirring mechanism 5 to work. The auxiliary mechanism 6 includes a fixed block 61 fixedly connected to the inner bottom wall of the control chamber 51. A semicircular groove 62 is opened on the fixed block 61. A fixed rod 63 is fixedly connected to the fixed block 61 at the center position of the semicircular groove 62. Fan-shaped driving blocks 64 are symmetrically arranged on both sides of the fixed rod 63. Each fan-shaped driving block 64 is slidably connected to the fixed rod 63 along an arc trajectory. The two fan-shaped driving blocks 64 are always sealed and slidably connected to the inner wall of the semicircular groove 62, and a second spring 65 is provided between the two fan-shaped driving blocks 64. A driving assembly 66 is provided above the two fan-shaped driving blocks 64 for driving the two fan-shaped driving blocks 64 to periodically move away from each other.
[0029] It should be noted that, by setting an auxiliary mechanism 6, the present invention can drive the two fan-shaped driving blocks 64 to periodically move away from each other through the driving component 66 during the continuous shaking of the driving water in the control chamber 51, and make the two fan-shaped driving blocks 64 periodically move closer to each other and reset under the elastic force of the second spring 65. The driving water can be disturbed by the two fan-shaped driving blocks 64, and the amplitude and frequency of the driving water fluctuations can be increased, so as to ensure that the energy generated when the ship shakes is sufficient to drive the stirring mechanism to work, thereby ensuring the stirring effect of the stirring mechanism on the refrigerant, and further ensuring the discharge effect of the air in the refrigerant.
[0030] The driving assembly 66 includes a U-shaped transmission plate 661 fixedly connected to the upper end of the fan-shaped driving block 64, and a U-shaped mounting block 662 is fixedly connected to the inside of the control chamber 51. A double-sided rack 663 is slidably connected to the U-shaped mounting block 662, and the double-sided rack 663 moves periodically in the vertical direction. A mounting seat 664 is provided on both sides of the U-shaped mounting block 662, and a rotating shaft 665 is rotatably connected to the mounting seat 664. The two sides of the rotating shaft 665 are fixedly connected with swing plates 666 through connecting blocks. The swing plates 666 are in contact with the lower wall of the U-shaped transmission plate 661 at the corresponding position, and a transmission gear 667 is fixedly connected to the center position of the rotating shaft 665. The two transmission gears 667 are respectively meshed with the two sides of the double-sided rack 663.
[0031] Specifically, the U-shaped mounting block 662 is fixedly connected to the inner wall of the control chamber 51 through a support rod.
[0032] The adaptive compensation mechanism 7 is used to ensure the working effect of the stirring mechanism 5 when the ship's shaking amplitude is small and the energy generated is small. The adaptive compensation mechanism 7 includes a unilateral rack 71 fixedly connected to the upper end of the bilateral rack 663, and a third spring 72 is provided between the unilateral rack 71 and the inner bottom wall of the control chamber 51. A DC motor 73 is fixedly connected to the inner wall of the control chamber 51, and a driving rod 74 is fixedly connected to the output end of the DC motor 73. An incomplete gear 75 is fixedly connected to the driving rod 74, and the incomplete gear 75 periodically meshes with the unilateral rack 71. A liquid level sensor 76 is fixedly connected to the upper end of the floating plate 52, and the liquid level sensor 76 is electrically connected to the DC motor 73.
[0033] Specifically, when the DC motor 73 drives the driving rod 74 to rotate, it will drive the incomplete gear 75 to periodically engage with the unilateral rack 71. When the incomplete gear 75 engages with the unilateral rack 71, it will drive the unilateral rack 71 to move downward. When the incomplete gear 75 is no longer engaged with the unilateral rack 71, it will move upward and reset under the elastic force of the third spring 72.
[0034] Specifically, when the double-sided rack 663 performs reciprocating vertical displacement, the transmission gear 667 will drive the rotating shaft 665 and the swing plate 666 to swing back and forth. When the swing plate 666 swings from bottom to top, the fan-shaped drive block 64 can be driven to rotate upward through the U-shaped transmission plate 661. When the swing plate 666 swings from top to bottom, the U-shaped transmission plate 661 and the fan-shaped drive block 64 rotate downward and reset under the action of their own gravity and the elastic force of the second spring 65.
[0035] Specifically, the liquid level sensor 76 can detect the amplitude and frequency of the fluctuation of the driving water liquid level by detecting the distance between the floating plate 52 and the top wall of the control chamber 51, and the frequency of the change of the distance.
[0036] Specifically, the PLC controller 47 controls the power of the DC motor 73 according to the amplitude and frequency of the driving water level fluctuation detected by the liquid level sensor 76 .
[0037] It should also be noted that, by providing the adaptive compensation mechanism 7, the present invention can detect the amplitude and frequency of the driving water level fluctuation in the control chamber 51 through the liquid level sensor 76 when the ship sways and drives the driving water to fluctuate, and transmit the detected data to the PLC controller 47 through an electrical signal, and further control the power of the DC motor 73 through the PLC controller 47: When the ship's swaying amplitude is small, the fluctuation of the driving water level is small, and the liquid level sensor 76 detects that the amplitude and frequency of the liquid level fluctuation are low. At this time, the PLC controller 47 controls the DC motor 73 with a high power, and the frequency of the incomplete gear 75 driving the unilateral rack 71 to move downward is relatively fast, which further makes the frequency of the reciprocating vertical displacement of the bilateral rack 663 relatively fast, and makes the frequency of the movement of the two fan-shaped driving blocks 64 relatively fast. At this time, the amplitude of the ship's swaying is not enough to drive the driving water to fluctuate to a large extent. Therefore, the relatively fast movement frequency of the two fan-shaped driving blocks 64 can enhance the fluctuation of the driving water and ensure the operation of the stirring mechanism 5. When the ship shakes with a large amplitude, the liquid level sensor 76 detects that the amplitude and frequency of the liquid level fluctuation are high. At this time, the power of the DC motor 73 controlled by the PLC controller 47 is low, and the frequency of the incomplete gear 75 driving the unilateral rack 71 to move downward is relatively slow, and the frequency of the movement of the two fan-shaped drive blocks 64 is relatively slow. At this time, the amplitude of the ship's shaking is sufficient to drive the driving water to fluctuate to a large extent. Therefore, the movement frequency of the two fan-shaped drive blocks 64 can be appropriately reduced to avoid over-driving and reduce energy consumption.
[0038] A flow control mechanism 8 is also provided inside the semicircular groove 62. The flow control mechanism 8 includes an electromagnetic coil 81 fixedly connected to one of the fan-shaped drive blocks 64. A movable magnet 82 is fixedly connected to the other fan-shaped drive block 64. An electronic throttle valve 83 is provided on the first infusion hose 21. The electromagnetic coil 81 is electrically connected to the electronic throttle valve 83.
[0039] Specifically, the PLC controller 47 controls the opening of the electronic throttle valve 83 according to the electrical signal generated by the change of magnetic flux in the electromagnetic coil 81. At the same time, the opening adjustment error of the electronic throttle valve 83 is less than ±3%, and the response time is less than 200ms.
[0040] In addition, the present invention is further provided with a flow control mechanism 8. In the process of the ship's shaking driving the water wave, the shaking of the ship can be fed back through the moving frequency of the two fan-shaped driving blocks 64, and the circulation rate of the refrigerant can be further adjusted according to the shaking of the ship. When the moving magnet 82 moves, the magnetic flux in the electromagnetic coil 81 will change periodically and generate a sinusoidal AC signal. The PLC controller 47 calculates the rate of periodic change of the magnetic flux in the electromagnetic coil 81 according to the received sinusoidal AC signal, thereby calculating the moving frequency of the moving magnet 82 relative to the electromagnetic coil 81. When the ship's shaking amplitude is small, the moving frequency of the two fan-shaped drive blocks 64 is relatively fast. At this time, the moving frequency of the moving magnet 82 relative to the electromagnetic coil 81 is relatively fast. The PLC controller 47 controls the opening of the electronic throttle valve 83 to increase, thereby increasing the circulation rate of the refrigerant when the ship is relatively stable, so as to improve the refrigeration effect of the refrigeration system. When the ship's shaking amplitude is large, the moving frequency of the two fan-shaped drive blocks 64 is relatively slow. At this time, the PLC controller 47 controls the opening of the electronic throttle valve 83 to decrease, thereby reducing the circulation rate of the refrigerant when the ship is shaking more, so as to avoid the mixing of air.
[0041] The present invention can be explained by the following operation mode: Before use, the storage tank 1, the transfer tank 2 and the heat exchange device 3 are fixedly installed at the designated position in the ship by fastening bolts, and then the storage tank 1 and the transfer tank 2 are connected through the first infusion hose 21, and the transfer tank 2 and the heat exchange device 3 are connected through the second infusion hose 22. The refrigerant is driven by the circulating pump to circulate in the compressor, the storage tank 1, the first infusion hose 21, the transfer tank 2, the second infusion hose 22 and the heat exchange device 3; During the operation of the ship, the shaking of the ship drives the transfer tank 2 to shake, so that the transfer tank 2 can move on the bottom wall of the fixed frame 41, so that the refrigerant flowing through the transfer tank 2 shakes with the transfer tank 2, so that the refrigerant can make the air inside the transfer tank 2 float upward when flowing through the inside of the transfer tank 2, and further discharge it to the space above the refrigerant in the transfer tank 2, so as to remove the air in the refrigerant, and then the air pressure in the space above the refrigerant in the transfer tank 2 is detected by the pressure sensor 46, and the automatic exhaust valve 45 is opened in time after the air is removed from the refrigerant to discharge the air; The shaking of the transfer tank 2 will also cause the driving water in the control chamber 51 to shake continuously, and the fluctuation of the driving water will drive the floating plate 52 to move up and down in the control chamber 51, thereby driving the rotating plate 58 to rotate through the connecting rod 53, the sleeve 510 and the pin 59, so that the transmission rod 56 rotates, and further drives the rotating rod 54 to rotate under the action of the bevel gear set 57, driving the multiple stirring rods 55 to perform circular motion, and stirring the refrigerant flowing through the transfer chamber 43; In the process of driving water fluctuation, the liquid level sensor 76 can detect the fluctuation amplitude and frequency of the driving water surface in the control chamber 51, and transmit the detected data to the PLC controller 47 through an electrical signal, and further control the power of the DC motor 73 through the PLC controller 47. When the swaying amplitude of the ship is small, the movement frequency of the two fan-shaped driving blocks 64 is relatively fast, and the two fan-shaped driving blocks 64 are controlled to move at a relatively fast movement frequency to enhance the fluctuation of the driving water. When the swaying amplitude of the ship is large, the movement frequency of the two fan-shaped driving blocks 64 is appropriately reduced to avoid over-driving. The shaking of the ship is fed back through the movement frequency of the two fan-shaped drive blocks 64, and the circulation rate of the refrigerant is further adjusted according to the shaking of the ship. When the shaking amplitude of the ship is small, the PLC controller 47 controls the opening of the electronic throttle valve 83 to increase, thereby increasing the circulation rate of the refrigerant when the ship is relatively stable. When the shaking amplitude of the ship is large, the PLC controller 47 controls the opening of the electronic throttle valve 83 to decrease, thereby reducing the circulation rate of the refrigerant when the ship is relatively shaking.
