Description

Technical Field

[0001] The invention relates to the technical field of leakage detection equipment, in particular to a leakage detection device for a water-cooled rectifier cabinet. Background Art

[0002] A rectifier cabinet is an electrical device used to convert alternating current into direct current. It is widely used in various industries and power systems, including power transmission, metallurgy, and chemical industries. The main function of a rectifier cabinet is to provide a stable direct current power supply to meet the power needs of equipment and systems. A water-cooled rectifier cabinet is a rectifier device that integrates a water cooling system. It is used to convert alternating current into direct current while dissipating heat through a water cooling system. This type of equipment is particularly suitable for applications in high-power and high-temperature environments. The water cooling system includes a cooling water pump, cooling water pipelines, a radiator or a cooling coil, etc. The cooling pipes are evenly distributed inside the rectifier cabinet to exchange heat with the internal hot air through the coolant to remove the heat generated by the rectifier and other components. This is one of the common cooling methods of the water cooling system. Leakage detection of water-cooled rectifier cabinets is an important measure to ensure equipment safety and stable operation. Since the water cooling system uses water as a cooling medium, any leakage may cause equipment failure, short circuit or other safety problems. Therefore, accurate leakage detection and timely maintenance are essential to maintaining the normal operation of the system.

[0003] The patent with announcement number CN212807509U discloses a leakage detection device for a water-cooled rectifier cabinet, whose structure includes a sensing rope, a drip collection cover and an alarm positioning module. The water-cooled rectifier cabinet has the characteristics of many water connection points, unstable cooling water pressure, and easy aging of cooling water pipes in the cabinet. The detection device uses a drip collection cover to concentrate the water droplets seeping from various tiny leakage points in the cabinet into the groove, allowing the sensing rope installed in the groove to sense the water droplets and convert them into electrical signals. After analysis and processing by the alarm positioning module, an alarm signal is sent in time. The switch signal can be transmitted to the rectifier cabinet control circuit to automatically cut off the power supply of the rectifier cabinet, and at the same time sent to other system control modules for alarm and cutting off related control equipment; when cooling water leaks, it can timely alarm and cut off the power supply to avoid safety accidents, and at the same time can timely remind maintenance personnel to carry out maintenance.

[0004] However, the above-mentioned prior art has the following shortcomings: during the use of the detection device, although it can respond to the leakage of the water-cooling pipe of the rectifier cabinet in a timely manner, it is impossible to locate the detailed position of the leakage, resulting in maintenance personnel needing to spend a certain amount of time to explore the leakage point. This situation not only prolongs the maintenance time, but may also increase the downtime of the equipment, thereby affecting the production efficiency and the normal operation of the equipment.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of an embodiment of the present invention based on its overall structure.

[0033] Reference Figures 1 to 8In the embodiment of the present invention, the leakage detection device of the water-cooled rectifier cabinet includes: a collecting box 4 for collecting the leaked coolant, a circulation system 3 for allowing the coolant to flow therein and fully exchanging heat between the coolant and the hot air is arranged on the collecting box 4, a rectifier cabinet 1 for mounting the rectifier is arranged at one end of the circulation system 3, a base 2 is fixedly connected to the bottom end of the rectifier cabinet 1, a liquid storage box 6 for collecting the leaked liquid is fixedly arranged in the base 2, the liquid storage box 6 is U-shaped, and the liquid storage box 6 is high in the middle and low at both ends, so that the leaked coolant flows to the liquid storage box 6 The liquid flows at both ends, a guide tube 5 is provided through the liquid storage box 6, a drainage tube 51 is provided through the guide tube 5, and the drainage tube 51 is connected with the bottom end of the collection box 4, the drainage tube 51 is made of transparent plastic, and the connection end of the drainage tube 51 and the collection box 4 is higher than the connection end of the drainage tube 51 and the guide tube 5, a push plate 63 is slidably provided in the liquid storage box 6, a baffle 64 is fixedly connected to the bottom end of the push plate 63, and two groups of baffles 64 are provided, and a group of liquid level sensors 65 are fixedly provided on one side of each group of baffles 64, and the bottom end of the guide tube 5 passes through the push plate 63;

[0034] A pigment box 41 is fixedly connected to the collecting box 4, and a liquid outlet 42 is formed at the bottom of the pigment box 41. Solid pigment 43 is arranged in the pigment box 41. The solid pigment 43 is titanium dioxide, which is an inorganic pigment and is commonly used for coloring water-based cooling liquids. It usually exhibits high stability and low corrosion. When a pipeline in the circulation system 3 leaks, the coolant will drip into the collecting box 4 at the bottom of the pipeline. At this time, the coolant will react with the solid pigment 43 to melt it, thereby reducing the solid pigment 43 below the leakage point, and drip from the liquid outlet 42 to the bottom of the collecting box 4, and finally enter the liquid storage box 6 through the drainage tube 51 and the guide tube 5 in turn, and contact the liquid level sensor 65 to make it send a signal, so that the maintenance personnel can quickly determine which section of the pipeline is leaking based on the pigment remaining on the inner wall of the drainage tube 51 made of transparent plastic, and then quickly locate the leakage point based on the missing position of the solid pigment 43 in the collecting box 4 below this section of the pipeline.

[0035] For this purpose, in the present technical solution, the liquid level sensor 65 adopts the existing technology and is a contact sensor, which is a device that directly contacts the liquid to measure its liquid level. This type of sensor determines the liquid level by directly interacting with the physical or electrical properties of the liquid.

[0036] Reference Figure 2The circulation system 3 includes a fixing member 34 fixedly connected to the inner wall of the rectifier cabinet 1. The fixing member 34 is provided with multiple groups and evenly distributed on the inner wall of the rectifier cabinet 1 to fix the feed pipe 31, the circulation pipe 32, the discharge pipe 33 and the collection box 4. The collection box 4 is provided with multiple groups. A group of collection boxes 4 is provided under each group of the feed pipe 31, the circulation pipe 32 and the discharge pipe 33. One end of the fixing member 34 is connected with the circulation pipe 32. The circulation pipe 32 is composed of multiple groups of straight pipes and arc pipes, evenly distributed. It is arranged on the inner wall of the rectifier cabinet 1, one end of the circulation pipe 32 is connected with the feed pipe 31, and the other end of the circulation pipe 32 is connected with the discharge pipe 33. One end of the feed pipe 31 and the discharge pipe 33 pass through the rectifier cabinet 1, and the bottom end of the fixing part 34 is fixedly connected with the collecting box 4. The coolant enters the circulation pipe 32 evenly coiled in the rectifier cabinet 1 through the feed pipe 31, exchanges heat with the hot air of the rectifier cabinet 1, reduces the temperature in the rectifier cabinet 1, and flows out of the rectifier cabinet 1 through the discharge pipe 33.

[0037] For illustration, in the present technical solution, the circulation system 3 adopts the existing technology, wherein one end of the feed pipe 31 and the discharge pipe 33 pass through the rectifier cabinet 1 and are connected to an external cooling system, such as a water pump or a cooling tower, to ensure that the coolant can flow smoothly.

[0038] The above solution can make it easier for maintenance personnel to detect and repair leakage points through multiple groups of collection boxes 4, thereby improving the reliability and maintenance efficiency of the system.

[0039] Reference Figures 5 to 9 , a flow-changing pipe 1 61 is connected through one side of the liquid storage box 6, and this end of the flow-changing pipe 1 61 passes through the base 2 and is located outside the base 2, and the flow-changing pipe 1 61 is U-shaped, and a flow-changing pipe 2 62 is connected through the other side of the liquid storage box 6, and this end of the flow-changing pipe 2 62 passes through the base 2 and is located outside the base 2, and the flow-changing pipe 2 62 is L-shaped, one end of the flow-changing pipe 1 61 passes through the rectifier cabinet 1, and is connected through one end of the discharge pipe 33, and one end of the flow-changing pipe 2 62 is connected through one end of the discharge pipe 33 that passes through the rectifier cabinet 1. When the baffle 64 is in the initial position, the two groups of baffles 64 respectively block the flow-changing pipe 1 61 and the flow-changing pipe 2 62, so that the coolant will not pass through the flow-changing pipe 1 61 and the flow-changing pipe 2 62 during the circulation process. The redirecting tube 2 62 enters the liquid storage box 6, and the push plate 63 is provided with a redirecting device 7 for changing the flow direction of the coolant when a large amount of leaked coolant accumulates in the liquid storage box 6, so that the leaked coolant in the liquid storage box 6 re-enters the circulation. The liquid storage box 6 is provided with an activating member 8 for adjusting the state of the redirecting device 7 according to the liquid level of the leaked coolant in the liquid storage box 6. When the push plate 63 in the liquid storage box 6 is pushed upward by the activating member 8 due to the rising liquid level of the leaked coolant in the liquid storage box 6, the two groups of baffles 64 at the lower end of the push plate 63 move upward synchronously to release the blockage of the redirecting tube 1 61 and the redirecting tube 2 62, so that the liquid storage box 6 is connected to the discharge pipe 33 through the redirecting tube 1 61 and the redirecting tube 2 62.

[0040] By adopting the above scheme, the coolant flowing out from the pipeline leakage in the circulation system 3 can be effectively collected through the liquid storage box 6, and the leakage of the coolant can be prevented, thereby ensuring the safety and reliability of the system. The liquid level sensor 65 in the liquid storage box 6 monitors the liquid level of the coolant in real time. When the liquid level exceeds the set value, an alarm signal will be issued, so that maintenance personnel can promptly discover and deal with the leakage problem, thereby reducing the system downtime. The liquid storage box 6 is equipped with a flow change pipe 1 61 and a flow change pipe 2 62. These pipes can guide the coolant back to the circulation system 3 when too much coolant accumulates, thereby avoiding the leakage of the coolant and reducing the maintenance workload.

[0041] Reference Fig.10 The flow-changing device 7 includes an insertion rod 71 fixedly connected to the top of the push plate 63. One end of the insertion rod 71 passes through the liquid storage box 6, the base 2 and the rectifier cabinet 1 in sequence, and a guide block 72 is fixedly connected to the outside of the insertion rod 71. The guide block 72 is spiral. There are four groups of guide blocks 72, which are evenly distributed on the outside of the insertion rod 71. The inner wall of the rectifier cabinet 1 is fixedly connected to a mounting frame 73. One end of the mounting frame 73 is rotatably connected to a rotating cylinder 74. The inner wall of the rotating cylinder 74 is provided with a slot adapted to the guide block 72. The insertion rod 71 When moving upward, it is plugged into the rotating cylinder 74, so that the slot provided on the inner wall of the rotating cylinder 74 is meshed and connected with the guide block 72, driving the rotating cylinder 74 to rotate ninety degrees. The top of the rotating cylinder 74 is fixedly connected to a connecting column 75, and the top of the connecting column 75 is fixedly connected to a gear 76. The flow-changing device 7 also includes a blocking outer member 77 arranged in the discharge pipe 33 and rotatably connected to the discharge pipe 33. The blocking outer member 77 is spherical and has a through hole. A blocking inner member 78 is rotatably connected to the blocking outer member 77. The plugging inner member 78 is spherical and has a through hole. In the initial state, the plugging outer member 77 has a through hole that is connected to the through hole on the plugging inner member 78, so that the coolant can flow in the discharge pipe 33. The top of the plugging inner member 78 is fixedly connected to a connecting column 2 79. One end of the connecting column 2 79 penetrates the plugging outer member 77 and the discharge pipe 33, and is fixedly connected to a gear 2 710. The gear 2 710 is meshed with the gear 1 76. When the push plate 63 moves up, the insertion rod 71 is pushed up, so that the insertion rod 7 1 is inserted into the rotating cylinder 74 and rotates under the action of the guide block 1 72. When the insertion rod 71 is inserted into the limit position in the rotating cylinder 74, the guide block 1 72 completely enters the rotating cylinder 74, causing the rotating cylinder 74 to rotate 90 degrees, driving the gear 1 76 to rotate, and causing the gear 2 710 meshing with the gear 1 76 to rotate 90 degrees synchronously, so that the blocking inner part 78 is also rotated 90 degrees, so that the connecting through holes on the blocking outer part 77 and the blocking inner part 78 are misaligned, so that the coolant cannot flow out through the discharge pipe 33.

[0042] By adopting the above scheme, the flow of coolant can be effectively managed through the flow diverter 7, ensuring that the cooling system can continue to work effectively when a leak occurs, ensuring that the temperature in the rectifier cabinet 1 can be effectively controlled, and avoiding potential damage caused by insufficient coolant in the water cooling system due to coolant leakage.

The limit groove 86 is provided with two groups, which are symmetrically distributed on both sides of the inner wall of the outer cylinder 85, and a plug column 87 is provided in the outer cylinder 85. The density of the plug column 87 is less than the density of the coolant , so that the plug post 87 rises with the rising level of the coolant leaked from the liquid storage box 6, and a slider 872 is fixedly connected to the outside of the plug post 87. Two groups of sliders 872 are provided, which are symmetrically distributed on both sides of the plug post 87. Each group of sliders 872 is slidably plugged with a group of limit grooves 86. A guide block 871 is fixedly connected to the outside of the plug post 87. The guide block 871 is spiral. Four groups of guide blocks 871 are evenly distributed on the outside of the plug post 87. The top end of the outer cylinder 85 is rotatably connected with a limiting member 88. The inner wall of the limiting member 88 is provided with a slot adapted to the guide block 871. When the plug post 87 moves up with the increase of the coolant leaked from the liquid storage box 6, it is plugged with the limiting member 88, so that the slot provided on the inner wall of the limiting member 88 It is meshed and connected with the guide block 871 to drive the limiting member 88 to rotate ninety degrees. A cavity 881 is provided at one end of the limiting member 88. A stopper 883 is slidably inserted at one end of the cavity 881. The top surface of the stopper 883 is an arc surface. A spring 882 is fixedly connected to one end of the stopper 883. One end of the spring 882 is fixedly connected to the inner wall of the cavity 881.

Two groups of ball 884 are provided, which are symmetrically distributed at the bottom end of the stopper 883. One end of the ball 884 abuts against the limiting plate 82. The friction between the stopper 883 and the limiting plate 82 is reduced by the ball 884. The limiting plate 82 is provided with four groups, which are evenly distributed on the liquid storage box 6 At the inner bottom end, when the liquid level of the leaked coolant in the liquid storage box 6 rises, and under the restriction of the limit groove 86 and the slider 872, the plug post 87 moves upward along the limit groove 86 until the plug post 87 is plugged into the limit member 88, so that the slot opened on the inner wall of the limit member 88 is meshed and connected with the guide block 2 871. When the guide block 2 871 is fully inserted into the limit member 88, it drives the limit member 88 to rotate ninety degrees, so that the stopper 883 rotates ninety degrees following the limit member 88, and the restriction of the stopper 883 on the limit plate 82 is released, so that the spring 1 83 returns to its original length, and under the action of the spring 1 83, the limit plate 82 moves up. During the upward movement of the limit plate 82, it abuts against the push plate 63 and pushes the push plate 63 to move up.

[0044] The above scheme is adopted: the activation part 8 can automatically respond when the coolant leakage increases, and the system state is automatically adjusted through the rise of the plug 87 and a series of mechanical linkages without human intervention. The system is adjusted before the maintenance personnel arrive at the scene, reducing potential losses such as equipment damage or production stoppage caused by coolant leakage.

[0045] The working principle of the present invention is: when the pipeline in the circulation system 3 leaks, the coolant will drip into the collection box 4 at the bottom of the pipeline. At this time, the coolant will contact the solid pigment 43 in the pigment box 41 in the collection box 4, so that the solid pigment 43 quickly dissolves in the cooling liquid and colors the coolant. As the coolant continues to leak, the solid pigment 43 below the leakage point is reduced and drips from the liquid outlet 42 to the bottom of the collection box 4. Finally, it enters the liquid storage box 6 through the drainage tube 51 and the guide tube 5 in turn, and contacts with the liquid level sensor 65 to make it send out a signal, giving an alarm, so that the maintenance personnel can carry out maintenance in time. During maintenance, according to the residual pigment on the inner wall of the drainage tube 51 made of transparent plastic, it is possible to quickly determine which section of the pipeline is leaking, and then according to the According to the missing position of the solid pigment 43 in the collecting box 4 below this section of the pipeline, the leakage point is quickly located for maintenance. After the maintenance is completed, the soaked solid pigment 43 in the pigment box 41 in the collecting box 4 below the leakage is dug out and filled with dry new solid pigment 43, and the drainage pipe 51 connected to this group of collecting boxes 4 is removed, flushed, and reinstalled. When the maintenance personnel are unable to carry out maintenance in time or the leakage of coolant at the leakage increases, as the coolant in the liquid storage box 6 increases, under the restriction of the limit groove 86 and the slider 872, the plug post 87 is moved upward along the limit groove 86 until the plug post 87 is plugged into the limit member 88, so that the slot opened on the inner wall of the limit member 88 is meshed and connected with the guide block 2 871. When the guide block 2 871 is fully inserted When the limit member 88 is inserted into the limit member 88, the limit member 88 is driven to rotate ninety degrees, so that the stopper 883 rotates ninety degrees with the limit member 88, and the limit of the stopper 883 on the limit plate 82 is released, so that the spring 1 83 recovers its original length, and under the action of the spring 1 83, the limit plate 82 moves up. During the upward movement of the limit plate 82, it abuts against the push plate 63 and pushes the push plate 63 to move up. When the push plate 63 moves up, it pushes the insertion rod 71 to move up, so that the insertion rod 71 is inserted into the rotating cylinder 74 and rotates under the action of the guide block 1 72. When the insertion rod 71 is inserted into the limit position in the rotating cylinder 74, the guide block 1 72 completely enters the rotating cylinder 74, so that the rotating cylinder 74 rotates ninety degrees, driving the gear 1 76 to rotate, so that the gear 2 710 meshing with the gear 1 76 rotates synchronously by ninety degrees. , so that the plugging inner part 78 is also rotated ninety degrees, so that the connecting through hole on the plugging outer part 77 and the plugging inner part 78 is misaligned, so that the coolant cannot flow out through the discharge pipe 33. At the same time as the push plate 63 moves up, the two groups of baffles 64 at the lower end of the push plate 63 move up synchronously, and the blockage of the flow-changing pipe 1 61 and the flow-changing pipe 2 62 is released, so that the liquid storage box 6 is connected to the discharge pipe 33 through the flow-changing pipe 1 61 and the flow-changing pipe 2 62. At this time, due to the misalignment of the connecting through hole on the plugging outer part 77 and the plugging inner part 78, the coolant cannot flow out through the discharge pipe 33, so that the coolant flows into the liquid storage box 6 through the flow-changing pipe 1 61, and the coolant in the liquid storage box 6 flows into the discharge pipe 33 through the flow-changing pipe 2 62, so that the coolant in the liquid storage box 6 re-enters the water cooling system.To prevent the water cooling system from being unable to work properly due to a reduction in coolant caused by leakage, when the maintenance is completed and the coolant in the liquid storage box 6 is discharged, the plug post 87 moves downward due to gravity, causing the plug post 87 to withdraw from the limiting member 88. Under the action of the guide block 2 871, the limiting member 88 rotates 90 degrees to reset, and then the reset rod 84 is pressed. During the pressing process, the limit plate 82 moves with the reset rod 84, compressing the spring 1 83 until the bottom end of the limit plate 82 abuts against the top arc surface of the stop block 883, and pushes the stop block 883 to move into the cavity 881. When the limit plate 82 moves When it reaches the lower end of the stopper 883, the stopper 883 is pushed out of the cavity 881 by the spring 2 882 to limit the limit plate 82. At this time, the push plate 63 loses the support of the limit plate 82 and slides downward, so that the two sets of baffles 64 block the flow-changing pipe 1 61 and the flow-changing pipe 2 62 again. As the push plate 63 slides downward, the insertion rod 71 is driven to move downward, so that the insertion rod 71 exits the inside of the rotating cylinder 74. Under the action of the guide block 1 72, the rotating cylinder 74 rotates 90 degrees to reset, driving the gear 1 76 to rotate, so that the connecting through holes on the blocking outer member 77 and the blocking inner member 78 are connected again. ; The solid pigment 43 in the collecting box 4 reacts with the coolant, and the solid pigment 43 below the leak point is reduced and drips from the liquid outlet 42. This change can be transmitted to the liquid storage box 6 through the drainage tube 51 and the guide tube 5, and triggers the liquid level sensor 65 to sound an alarm. This method allows maintenance personnel to quickly determine the specific location of the leak by observing the change in the pigment, thereby improving the efficiency of leak detection and positioning. The liquid storage box 6 is equipped with a diverter tube 1 61 and a diverter tube 2 62. When the coolant accumulates beyond a certain level, the diverter device 7 will automatically adjust the coolant flow direction and re-introduce the excess coolant into the circulation system 3. This design effectively prevents the leakage of the coolant, ensures the normal operation of the system, and reduces the maintenance cost caused by the coolant leakage. The activation part 8 can automatically start when the coolant leakage increases, and automatically adjust the system state through the rise of the plug 87 and the mechanical linkage device without manual intervention. This automatic response mechanism can adjust the system state in time before the maintenance personnel arrive at the site, reduce the potential risk of equipment damage or production stoppage caused by coolant leakage, and improve the reliability and safety of the system. ,
