Description

TECHNICAL FIELD

[0001] The utility model relates to the field of battery equipment especially to a hydrogen production power supply with water cooling assembly. BACKGROUND

[0002] In the power generation system, when the direct current or alternating current generated by the generator set is processed by the power settings such as inverter and transformer, the unstable direct current or alternating current directly generated is converted into high-voltage alternating current or high-voltage alternating current. Especially for new energy power generation, the source of power such as wind energy or light is easily affected by natural factors, so the directly converted power is not stable. In the field of electrolytic hydrogen production, such unstable power supply greatly affects the working efficiency and safety of the electrolytic tank. Therefore, the directly generated power needs to be converted again, that is, rectified and pressurized by the hydrogen production power supply to convert it into high-quality power transmission to the electrolytic tank.

[0003] The hydrogen production power supply will emit a large amount of heat during work. In order to improve the working stability of the hydrogen production power supply, it needs to be cooled. The common cooling methods at present are mainly water cooling and air cooling, among which water cooling is widely used due to its high heat dissipation efficiency. The water cooling system of the power supply mainly includes a heat exchange element in direct contact with the power supply, a liquid inlet pipe for delivering cooling liquid to the heat exchange element, and a liquid outlet pipe for discharging the cooling liquid in the heat exchange element. The liquid inlet pipe, the liquid outlet pipe and the heat exchange element are connected by hoses.

[0004] For the related technology in the above, the hydrogen production power supply is usually placed in batches, and each independent power supply has a separate heat exchange element. When cooled by the water cooling system, in order to simplify the delivery structure of the cooling liquid, only one set of liquid inlet pipe and liquid outlet pipe is usually provided between all the heat exchange elements. However, if any hose is damaged or aged and needs to be replaced, in order to avoid the overflow of the cooling liquid, the damaged hose needs to be cut off from the heat exchange element and the heat exchange element needs to be in a closed state. When the hose is replaced, the heat exchange element is connected to the liquid inlet pipe and the liquid outlet pipe through the hose. Therefore, during the replacement of the hose, the cooling liquid in the heat exchange element cannot participate in the circulation, affecting the cooling effect of the hydrogen production power supply.

The assembling pipe 32 and the through pipe 41 are threadedly connected, so that the mounting pipe 31 and the through pipe 41 are in contact and communication, and at this time, the hose 3 is in communication with the threaded connecting pipe one 4 through the through pipe 41.

[0034] With reference to Figure 1 and Figure 3 The inlet pipe 21, the outlet pipe 22 and the heat exchange plates 23 are all fixedly connected with a threaded connecting pipe two 24 corresponding to the threaded connecting pipe one 4, and when the threaded connecting pipe one 4 is threadedly matched with the threaded connecting pipe two 24, the hose 3 is in communication with the inlet pipe 21 and the heat exchange plates 23 and the heat exchange plates 23 and the outlet pipe 22, at this time, the cooling liquid enters the heat exchange plates 23 through the inlet pipe 21, absorbs the heat generated by the power supply units 11, and is discharged through the outlet pipe 22.

[0035] With reference to Figure 1 and Figure 3The isolation plate 30 is arranged in the hose 3, and the isolation plate 30 divides the inner cavity of the hose 3 into two conveying channels. The separation plate 311 corresponding to the isolation plate 30 is arranged in the mounting pipe 31, the baffle 312 is arranged on both sides of the separation plate 311, the rotating rod 313 perpendicular to the mounting pipe 31 is fixedly connected to the baffle 312, the rotating rod 313 penetrates through the mounting pipe 31 and is rotationally connected with the mounting pipe 31. In the initial state, the baffle 312 is attached to the separation plate 311, at this time, the cooling liquid entering the mounting pipe 31 is divided under the action of the separation plate 311 and is uniformly input into the two conveying channels.

[0036] Referring to Figure 1 and Figure 3 When one of the conveying channels in the hose 3 is damaged, the corresponding rotating rod 313 can be rotated to block the cavity between the mounting pipe 31 and the separation plate 311 by the baffle 312, thereby reducing the probability of leakage of the cooling liquid from the damaged conveying channel, and at the same time, the cooling liquid flows through the other channel, thereby reducing the risk of affecting the power supply member 11. The sealing gasket 314 is arranged in the circumferential direction of the baffle 312, and when the baffle 312 is in contact with the inner wall of the mounting pipe 31, the sealing gasket 314 is attached to the inner wall of the mounting pipe 31, thereby facilitating the blocking effect of the baffle 312.

[0037] Referring to Figure 2 and Figure 3 The two through pipes 41 are arranged, and in the normal state, any one of the through pipes 41 is connected with the hose 3, and the other through pipe 41 is in an idle state. The two through pipes 41 are provided with on-off valves, the on-off valve comprises a blocking ball 331 and a rotating handle 332, the blocking ball 331 is located in the through pipe 41 and is attached to the inner wall of the through pipe 41, one end of the rotating handle 332 is connected with the blocking ball 331, the other end penetrates through the through pipe 41 and is rotationally connected with the through pipe 41, and the rotating handle 332 is arranged perpendicular to the through pipe 41. The connecting hole 333 is arranged in the diameter direction of the blocking ball 331, the axis of the connecting hole 333 is perpendicular to the rotating rod 313, and when the rotating handle 332 is rotated, the rotating handle 332 drives the blocking ball 331 to rotate, thereby controlling the flow and disconnection of the cooling liquid in the through pipe 41. For the through pipe 41 connected with the hose 3, the on-off valve is in an open state, and for the idle through pipe 41, the on-off valve is in a closed state.

For the idle through pipe 41, when the end cover is buckled on the outer side of the through pipe 41, the elastic ring 421 is clamped in the annular groove 411, the through pipe 41 limits the end cover through the cooperation of the annular groove 411 and the elastic ring 421, thereby blocking the through pipe 41 by the end cover to prevent foreign matters from entering the through pipe 41.

[0039] Referring to Figure 1 and Figure 3 When the hose 3 needs to be replaced due to aging or damage, first, the new hose 3 is connected to the spare through pipe 41 through the corresponding installation pipe 31 and the assembly pipe 32. After the connection is completed, the on-off valve of the through pipe 41 at both ends of the new hose 3 is opened, and the on-off valve of the through pipe 41 at both ends of the hose 3 to be replaced is closed.

The blocking ball 331 is further provided with a rotating hole 334 in communication with the connecting hole 333. At this time, the rotating hole 334 is located at one end of the blocking ball 331 facing the hose 3. When the hose 3 is replaced, the stop lever 44 of the through pipe 41 at the end of the hose 3 is rotated out of the exhaust hole 43 along the direction of the flow of the cooling liquid, so that the transverse hole 442 is in communication with the outside. At this time, the gas in the hose 3 is sequentially discharged along the rotating hole 334, the connecting hole 333, the exhaust hole 43 and the transverse hole 442, thereby reducing the probability of affecting the heat exchange effect after the gas enters the heat exchange plate 23.

[0042] Referring to Figure 1 The outlet pipe 22 is provided with a temperature sensor at the end portion. The temperature sensor is used to sense the temperature of the cooling liquid at the outlet pipe. The placing cabinet 1 is provided with an audible and visual alarm 1. The temperature sensor is electrically connected to the audible and visual alarm 1. When the temperature of the power supply member 11 abnormally rises, the temperature of the cooling liquid discharged from the outlet pipe 22 also rises. When the temperature of the cooling liquid in the outlet pipe 22 is higher than the set threshold value, the temperature sensor is triggered and sends an electrical signal to the audible and visual alarm 1, so that the audible and visual alarm 1 sends an alarm. This is convenient for the operator to monitor the temperature of the power supply member 11 and adjust the opening degree of the related valves of the inlet pipe 21 and the outlet pipe 22.

[0043] Referring to Figure 1The inlet pipe 21, the outlet pipe 22 and the circulation system are closed, and the pressure sensor is arranged at any position of the inlet pipe 21 and the outlet pipe 22. The placing cabinet 1 is further provided with the audible and visual alarm two which is electrically connected with the pressure sensor. When the cooling liquid leaks, the pressure in the inlet pipe 21 or the outlet pipe 22 decreases, and when the pressure sensor detects that the pressure in the inlet pipe 21 or the outlet pipe 22 is lower than a threshold value, the pressure sensor triggers and sends an electric signal to the audible and visual alarm two, so that the audible and visual alarm prompts the operator, and then the leakage of the cooling liquid is monitored.

[0044] The implementation principle of the hydrogen production power supply with the water cooling assembly is as follows: the heat exchange plate 23 in the placing cabinet 1 directly contacts with the power supply 11, is connected with the inlet pipe 21 and the outlet pipe 22 through the hose 3, forms a closed water cooling circulation system, the cooling liquid circulates in the system, exchanges heat through the heat exchange plate 23, carries away the heat generated by the power supply 11, and makes the power supply 11 work at a suitable temperature. Two through pipes 41 are arranged, one of the through pipes 41 is kept idle, when the hose 3 needs to be replaced, the new hose 3 is connected with the idle through pipe 41 through the mounting pipe 31 and the assembling pipe 32, then the hose 3 which needs to be replaced is cut off from the cooling liquid circulation pipeline through the control switch valve and is disassembled, and when the hose 3 is replaced, the circulation of the cooling liquid in the corresponding heat exchange plate 23 does not need to be cut off, so that the probability that the cooling effect of the power supply 11 is affected when the hose 3 is replaced is reduced.

[0045] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
