[0002] Compressed air energy storage is a large-scale physical energy storage method that can solve the problem of grid connection of unstable renewable energy such as photovoltaic and wind power, and improve its energy utilization rate. The main components of traditional compressed air energy storage include compressor, compressed air storage, combustion chamber, expander and motor / generator, etc. During the energy storage process, air enters the compressor from the atmosphere, is compressed into high-pressure air and stored in the compressed air storage.

[0003] In the process of storing air energy, it is necessary to adjust the operation of the equipment according to the energy storage status. Currently, most control devices are electronic pressure switches, which control the air compression energy storage device according to the pressure. Since there is no backup monitoring and processing equipment, if the control device is damaged, it cannot control the air compression energy storage device, and the equipment will be damaged due to excessive storage pressure. For this reason, the present application proposes an air compression energy storage control device with an alarm function. Utility Model Content

[0004] The purpose of the utility model is to provide an air compression energy storage control device with an alarm function in order to solve the above-mentioned problems. Through the pressure controller and the mechanical monitoring mechanism, two-level supervision is realized to ensure the safety of the use of the air compression energy storage equipment. At the same time, a pressure relief alarm function is also provided, thereby solving the problems mentioned in the background technology.

[0005] In order to solve the above problems, the utility model provides a technical solution:

[0007] As a preferred solution of the utility model, a slip ring is slidably connected inside the fixed cylinder and above the sealing piston, a spring is fixedly connected between the slip ring and the sealing piston, an adjusting bolt is threadedly connected inside the fixed cylinder, and the bottom end of the adjusting bolt passes through the fixed cylinder and is rotatably connected to the slip ring.

[0008] As a preferred solution of the utility model, an auxiliary rod is slidably connected inside the fixed cylinder, the bottom end of the auxiliary rod passes through the fixed cylinder and is fixed to the top of the slip ring, and scale lines are arranged outside the auxiliary rod.

[0009] As a preferred solution of the utility model, two slideways are symmetrically arranged inside the fixed cylinder, and the two slideways are both slidably connected to limit blocks, and the limit blocks are fixed to the slip ring.

[0010] As a preferred solution of the utility model, a retaining ring is fixedly connected inside the fixed cylinder and below the sealing piston, and the retaining ring is located below the pressure relief pipe.

[0011] As a preferred solution of the utility model, an isolation diaphragm is fixedly connected inside the pressure controller, and a sensor silicon chip is fixedly connected inside the pressure controller and above the isolation diaphragm.

[0012] The beneficial effects of the utility model are as follows: by arranging a fixed cylinder connected to the air path above the air guide block, and arranging a sealing piston inside the fixed cylinder, the sealing piston can slide mechanically according to the air pressure to control the sealing or opening and closing of the pressure relief pipe. If the pressure controller is damaged, the internal pressure cannot be monitored and adjusted, and the high air pressure will lift the sealing piston. At this time, the gas is discharged through the pressure relief pipe, which can not only achieve pressure relief and ensure the safety of the air compression energy storage equipment, but also monitor the gas through the airflow detector, thereby realizing secondary supervision and cooperating with the buzzer for alarm. At the same time, the distance between the sealing piston and the slip ring is adjustable, thereby changing the pressure required for the spring deformation, and adapting to monitoring use under different pressure environments.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: an air compression energy storage control device with an alarm function, comprising an air compression accumulator 1, a pressure controller 5 and a fixed cylinder 8. An industrial computer 2 is arranged on one side of the air compression accumulator 1. An air guide block 3 is fixedly connected to the top of the air compression accumulator 1. An air path 4 is provided inside the air guide block 3. The high-pressure air in the air compression accumulator 1 can be transported to the pressure controller 5 and the fixed cylinder 8 through the air path 4 inside the air guide block 3, thereby facilitating the subsequent dual monitoring of the air pressure. The pressure controller 5 is installed on the top of the industrial computer 2 by means of threads, and the bottom end of the pressure controller 5 extends to Inside the air path channel 4, a fixed cylinder 8 is installed on the top of the air guide block 3 by means of a thread, the fixed cylinder 8 is communicated with the air path channel 4, a pressure relief pipe 9 is fixedly connected to one side of the fixed cylinder 8, and an airflow detector 10 is fixedly connected to the inside of the pressure relief pipe 9. On the one hand, pressure relief can be achieved to prevent the internal pressure of the air compression accumulator 1 from being too high. On the other hand, the airflow detector 10 inside the pressure relief pipe 9 detects the flow of gas, and a sealing piston 11 is slidably connected inside the fixed cylinder 8. A buzzer 20 is fixedly connected to the top of the air compression accumulator 1 and on one side of the air guide block 3. After the pressure is relieved inside the pressure relief pipe 9, an alarm message can be issued according to the detection of the airflow detector 10.

[0022] Furthermore, a slip ring 13 is slidably connected inside the fixed cylinder 8 and located above the sealing piston 11, a spring 14 is fixedly connected between the slip ring 13 and the sealing piston 11, an adjusting bolt 15 is threadedly connected inside the fixed cylinder 8, the bottom end of the adjusting bolt 15 penetrates the fixed cylinder 8 and is rotatably connected to the slip ring 13, and the slip ring 13 is driven to slide inside the fixed cylinder 8 by the adjusting bolt 15, so that the distance between it and the sealing piston 11 can be changed. When the free expansion space of the spring 14 changes, the pressure required for its deformation also changes, which can change the force required for the sealing piston 11 to squeeze it, so as to meet the monitoring requirements of different air compression accumulators 1.

[0023] Furthermore, an auxiliary rod 16 is slidably connected inside the fixed cylinder 8, and the bottom end of the auxiliary rod 16 passes through the fixed cylinder 8 and is fixed to the top of the slip ring 13. A scale line 17 is set on the outside of the auxiliary rod 16. Through the scale line 17 on the auxiliary rod 16, the pressure required for the deformation of the spring 14 can be specifically checked, and then coordinated with the work of the pressure controller 5.

[0024] Furthermore, two slideways 18 are symmetrically provided inside the fixed cylinder 8, and both slideways 18 are slidably connected with limit blocks 19. The limit blocks 19 are fixed to the slip ring 13. When the slip ring 13 moves, it drives the limit blocks 19 to slide inside the slideways 18, and then the lower dead point of the movement of the slip ring 13 can be controlled under the cooperation of the slideways 18 and the limit blocks 19, thereby preventing the gap between the slip ring 13 and the retaining ring 12 from being too small, resulting in the sealing piston 11 being unable to move upward.

[0025] Furthermore, a retaining ring 12 is fixedly connected inside the fixed cylinder 8 and below the sealing piston 11, and the retaining ring 12 is located below the pressure relief pipe 9, which can block the sealing piston 11 and prevent it from moving downward without a lower limit, thereby ensuring the effect of being used in conjunction with the slip ring 13.

[0026] Furthermore, an isolation diaphragm 6 is fixedly connected inside the pressure controller 5 , and a sensor silicon chip 7 is fixedly connected inside the pressure controller 5 and above the isolation diaphragm 6 .

[0027] In summary: when the air compression accumulator 1 is working, it compresses the air to store energy. As the internal air pressure of the air compression accumulator 1 increases, the internal air pressure enters the air path channel 4 inside the air guide block 3. At this time, the pressure is transmitted to the sensor silicon chip 7 through the isolation diaphragm 6, causing the resistance value of the sensor silicon chip 7 to change, thereby causing the output voltage of the detection system to change. When the pressure controller 5 senses the pressure change, it sends a control signal to control the operation of the air compression accumulator 1. If the pressure controller 5 is damaged, the pressure of the air compression accumulator 1 continues to increase, and the air pressure entering the fixed cylinder 8 through the air path channel 4 pushes the sealing piston 11 upward, thereby compressing the spring 14. When the sealing piston 11 cannot seal the pressure relief pipe 9, the gas is discharged through the pressure relief pipe 9, which achieves pressure relief on the one hand and avoids excessive pressure inside the air compression accumulator 1. On the other hand, the air flow detector 10 inside the pressure relief pipe 9 detects the flow of gas, and the buzzer 20 can sound an alarm at this time, which serves as an alarm. By rotating the adjusting bolt 15 to drive the slip ring 13 to slide inside the fixed cylinder 8, the distance between it and the sealing piston 11 can be changed. At this time, the free expansion space of the spring 14 changes, and the pressure required for its deformation also changes, thereby changing the force required for the sealing piston 11 to squeeze it, so as to meet the monitoring needs of different air compression accumulators 1. When the slip ring 13 moves, it drives the auxiliary rod 16 to move. Through the scale line 17 on the auxiliary rod 16, the pressure required for the deformation of the spring 14 can be specifically checked, and then cooperate with the work of the pressure controller 5 to avoid the gas from being discharged from the inside of the pressure relief pipe 9 in advance when the control pressure set by the pressure controller 5 is not reached, thereby ensuring the accuracy of monitoring the air compression accumulator 1.
