DETAILED DESCRIPTION
[0026] In order to make the purpose, technical scheme and advantages of the utility model more clearly understood, the utility model is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0027] The specific implementation of the utility model is described in detail below in combination with specific embodiments.
[0028] Please refer to Figures 1 to 8The utility model discloses an alcohol hydrogen storage pressure regulating device, alcohol hydrogen storage pressure regulating device includes: the transverse welding on alcohol hydrogen storage equipment's mounting seat 1, the fixed mounting of mounting seat 1 has the transverse adjusting cylinder 2, and the one end opening of adjusting cylinder 2 installs the cover 21, and the other end opening of adjusting cylinder 2 fixed mounting has with alcohol hydrogen storage equipment's communication pipe 3 that communicates, and the pressure sensor 4 is installed on communication pipe 3, and the fixed mounting of adjusting cylinder 2 has with its inside communication exhaust pipe 22, and exhaust pipe 22 is close to cover 21 setting, and the fixed mounting of mounting seat 1 has mount 8, and the fixed mounting of mount 8 has the transverse air cylinder 5, and the output of air cylinder 5 is fixedly connected with telescopic link 6, and the end fixed connection of telescopic link 6 has the piston 7 slidingly connected in adjusting cylinder 2 inside, and the annular recess 71 is seted up on the ring wall of piston 7, and the annular sealing rubber strip 72 is installed in annular recess 71, and the annular sealing rubber strip 72 is with the inner chamber of adjusting cylinder 2 interference fit.
[0029] It needs to be explained that the device in the utility model is installed above the alcohol hydrogen storage equipment, is used for balancing the internal pressure of alcohol hydrogen storage, and the internal pressure of alcohol hydrogen storage is monitored in real time through the pressure sensor 4. When the internal pressure of alcohol hydrogen storage is reduced due to the influence of external environment, the pressure sensor 4 immediately collects and transmits monitoring data. It sends the pressure change information to the control unit (not shown in the figure, which can be integrated in the controller similar to PLC and other equipment, which is a common technical means in the technical field, and therefore, it is not necessary to make too much elaboration) connected thereto, and the control unit judges according to the preset pressure threshold value after receiving the signal. If the current pressure is lower than the normal working range, an instruction will be sent to control the cylinder 5 to start working. After receiving the start instruction, the internal structure of the cylinder 5 starts to work, and the telescopic rod 6 moves towards the adjusting cylinder 2. Since the telescopic rod 6 is fixedly connected to the piston 7 at the end, the piston 7 slides in the adjusting cylinder 2. The annular groove 71 is provided on the ring wall of the piston 7, and the annular sealing rubber strip 72 installed therein is in interference fit with the inner cavity of the adjusting cylinder 2. This design ensures the good sealing performance of the piston 7 when sliding in the adjusting cylinder 2, avoiding gas leakage. With the movement of the piston 7 to the inside of the adjusting cylinder 2, the air originally existing in the adjusting cylinder 2 is compressed. One end of the adjusting cylinder 2 is connected to the alcohol hydrogen storage equipment through the communication pipe 3. The compressed air forms a higher pressure in the adjusting cylinder 2 than the internal pressure of the alcohol hydrogen storage equipment. Therefore, this part of high-pressure air flows to the alcohol hydrogen storage equipment through the communication pipe 3, thereby supplementing and improving the internal pressure of the alcohol hydrogen storage equipment, and restoring it to the normal working range. Conversely, when the internal pressure of the alcohol hydrogen storage is too high due to the influence of the external environment, the pressure sensor 4 also transmits the monitoring data to the control unit, and the control unit sends an instruction to control the cylinder 5 to work. The telescopic rod 6 drives the piston 7 to move away from the communication pipe 3, so that the space in the adjusting cylinder 2 increases, the pressure decreases, and part of the high-pressure gas in the alcohol hydrogen storage equipment enters the adjusting cylinder 2 through the communication pipe 3 and is discharged to the outside environment through the exhaust pipe 22, thereby reducing the internal pressure of the alcohol hydrogen storage equipment and maintaining its stable operation. The utility model monitors the internal pressure of the alcohol hydrogen storage equipment in real time through the pressure sensor 4, controls the movement of the piston 7 in the adjusting cylinder 2 through the cylinder 5, monitors and compensates or releases the pressure in the alcohol hydrogen storage equipment in real time, maintains the stability of the pressure, and ensures the safety of the alcohol hydrogen storage equipment during transportation.
