Description

Technical Field

[0001] The utility model application relates to the technical field of diaphragm accumulators, in particular to a diaphragm accumulator with a leakage monitoring function. Background Art

[0002] A diaphragm accumulator is a device used to store fluid pressure energy. A diaphragm is used to isolate gas or liquid from compressed air or nitrogen. A diaphragm accumulator usually consists of a container for storing pressurized gas, a movable diaphragm and a fluid storage area. When compressed gas enters the container, the diaphragm moves toward the fluid, causing the fluid to be compressed or pushed into the fluid storage area, thereby forming energy storage.

[0003] However, in the prior art, as the use time increases, the material of the diaphragm accumulator may age and fatigue, resulting in a weakening of the diaphragm elasticity, increasing the risk of leakage, and causing liquid or gas to leak into the surrounding environment, which will lead to loss of energy storage and may even cause environmental pollution. Since the diaphragm accumulator is usually enclosed inside the equipment, it is relatively difficult to detect leakage. If the leakage is not discovered and handled in time, it may affect the normal operation of the system. Utility Model Content

[0004] In order to solve the problem that the material of the diaphragm accumulator may age and fatigue, resulting in weakened diaphragm elasticity, increased leakage risk, and liquid or gas leakage into the surrounding environment, which will lead to loss of energy storage and may even pollute the environment, since the diaphragm accumulator is usually enclosed inside the equipment, leakage detection is relatively difficult. If the leakage is not discovered and handled in time, it may affect the normal operation of the system. The utility model provides a diaphragm accumulator with a leakage monitoring function to solve the above-mentioned problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A diaphragm accumulator with a leakage monitoring function comprises a diaphragm accumulator assembly, the diaphragm accumulator assembly comprises a diaphragm accumulator lower shell, the upper part of the diaphragm accumulator lower shell is fixedly connected to the diaphragm accumulator upper shell, the diaphragm accumulator upper shell and the diaphragm body are installed inside, the upper part of the diaphragm accumulator upper shell is fixedly connected to a monitoring mechanism, the monitoring mechanism comprises a connecting pipe, a sliding rheostat body and a fixed box, the connecting pipe is fixedly connected to the diaphragm accumulator upper shell, and the upper part of the connecting pipe is fixedly connected to a piston shell, the piston shell is slidably connected to the piston body, the upper part of the piston body is fixedly connected to a connecting rod, and the upper part of the connecting rod is fixedly connected to a No. 1 connecting plate, a variable resistance plate is fixedly connected to the side of the No. 1 connecting plate, the sliding rheostat body is fixedly connected to the upper part of the upper shell of the diaphragm accumulator, the variable resistance plate is fitted with the surface of the sliding rheostat body, the fixed box is fixedly connected to the upper part of the upper shell of the diaphragm accumulator, a monitoring bulb is installed inside the fixed box, the monitoring bulb is provided with an illuminance measuring instrument, the illuminance measuring instrument is fixedly connected to the inside of the fixed box, a No. 1 connecting wire is fixedly connected to the upper part of the variable resistance plate, one end of the No. 1 connecting wire is fixedly connected to the monitoring bulb, a No. 2 connecting wire is fixedly connected to the bottom of the monitoring bulb, one end of the No. 2 connecting wire is electrically connected to the power supply, and the power supply is electrically connected to the upper part of the sliding rheostat body.

[0007] Furthermore, two limit rods are fixedly connected to the upper part of the upper shell of the diaphragm accumulator, and the two limit rods are symmetrically distributed on both sides of the connecting pipe.

[0008] Furthermore, two limit plates are fixedly connected to the side of the No. 1 connecting plate, and the two limit plates are symmetrically distributed on the surface of the No. 1 connecting plate, and the limit rod is slidably plugged into the limit plate.

[0009] Furthermore, a fixing frame is fixedly connected to the upper portion of the upper shell of the diaphragm accumulator, and a second connecting plate is fixedly connected to the side of the fixing frame.

[0010] Furthermore, a telescopic rod is fixedly connected to the bottom of the second connecting plate, and the telescopic rod is fixedly connected to the upper part of the first connecting plate.

[0011] Furthermore, a spring is arranged on the surface of the telescopic rod, one end of the spring is fixedly connected to the upper portion of the No. 1 connecting plate, and the other end of the spring is fixedly connected to the bottom portion of the No. 2 connecting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, when the upper shell of the diaphragm accumulator is pressurized, high-pressure gas is stored inside the diaphragm body. The pressure between the upper shell of the diaphragm accumulator and the diaphragm body is transmitted to the inside of the piston shell through the connecting pipe. At this time, the piston body will be pushed upward, and the connecting rod and the No. 1 connecting plate will move upward, driving the variable resistor plate to move upward along the surface of the sliding variable resistor body. When the variable resistor plate moves upward along the sliding variable resistor body, the resistance of the entire circuit will decrease. At this time, the brightness of the monitoring bulb will increase. The brightness of the monitoring bulb is monitored by the illuminance measuring instrument. When the diaphragm body leaks, the resistance inside the entire circuit will increase, and the brightness of the monitoring bulb will decrease. At this time, the monitoring data of the illuminance measuring instrument will find abnormalities, which is convenient for leak detection and monitoring of the diaphragm body.

[0014] 2. In the utility model, when the connecting rod pushes the No. 1 connecting plate to move downward, the limit plate will slide along the limit rod, and the movement of the No. 1 connecting plate will be limited by the limit rod and the limit plate, thereby improving the stability of the No. 1 connecting plate during movement. At the same time, during the upward movement of the No. 1 connecting plate, the telescopic rod and the spring are compressed. When the diaphragm body leaks, the internal pressure will decrease, and the telescopic rod and the spring will push the No. 1 connecting plate to move downward, thereby ensuring that the monitoring data of the illuminance meter is accurate.

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference Figure 1-Figure 5A diaphragm accumulator with a leakage monitoring function comprises a diaphragm accumulator assembly 1, the diaphragm accumulator assembly 1 comprises a diaphragm accumulator lower shell 11, a diaphragm accumulator upper shell 12 is fixedly connected to the upper part of the diaphragm accumulator lower shell 11, a diaphragm accumulator upper shell 12 and a diaphragm main body 13 are installed inside the diaphragm accumulator upper shell 12, a monitoring mechanism 2 is fixedly connected to the upper part of the diaphragm accumulator upper shell 12, the monitoring mechanism 2 comprises a connecting pipe 21, a sliding rheostat main body 211 and a fixed box 26, the connecting pipe 21 is fixedly connected to the diaphragm accumulator upper shell 12, and a piston shell 22 is fixedly connected to the upper part of the connecting pipe 21, a piston body 212 is slidably connected inside the piston shell 22, a connecting rod 213 is fixedly connected to the upper part of the piston body 212, and a No. 1 connecting plate is fixedly connected to the upper part of the connecting rod 213 23. A variable resistor plate 214 is fixedly connected to the side of the No. 1 connecting plate 23. The sliding variable resistor body 211 is fixedly connected to the upper part of the upper shell 12 of the diaphragm accumulator. The variable resistor plate 214 is in contact with the surface of the sliding variable resistor body 211. The fixed box 26 is fixedly connected to the upper part of the upper shell 12 of the diaphragm accumulator. A monitoring bulb 215 is installed inside the fixed box 26. The monitoring bulb 215 is provided with an illuminance measuring instrument 218. The illuminance measuring instrument 218 is fixedly connected to the inside of the fixed box 26. A No. 1 connecting wire 216 is fixedly connected to the upper part of the variable resistor plate 214. One end of the No. 1 connecting wire 216 is fixedly connected to the monitoring bulb 215. A No. 2 connecting wire 217 is fixedly connected to the bottom of the monitoring bulb 215. One end of the No. 2 connecting wire 217 is electrically connected to the power supply. The power supply is electrically connected to the upper part of the sliding variable resistor body 211.

[0024] Specifically, when the upper shell 12 of the diaphragm accumulator is pressurized, high-pressure gas is stored inside the diaphragm body 13. The pressure between the upper shell 12 and the diaphragm body 13 of the diaphragm accumulator is transmitted to the inside of the piston shell 22 through the connecting tube 21. At this time, the piston body 212 will be pushed upward, and the connecting rod 213 and the No. 1 connecting plate 23 will move upward, driving the variable resistor plate 214 to move upward along the surface of the sliding variable resistor body 211. When the variable resistor plate 214 moves upward along the sliding variable resistor body 211, the resistance of the entire circuit will decrease. At this time, the brightness of the monitoring bulb 215 will increase. The brightness of the monitoring bulb 215 is monitored by the illuminance measuring instrument 218. When the diaphragm body 13 leaks, the resistance inside the entire circuit will increase, and the brightness of the monitoring bulb 215 will decrease. At this time, the monitoring data of the illuminance measuring instrument 218 will find abnormalities, which is convenient for leak detection and monitoring of the diaphragm body 13.

[0025] As an optimization solution, Figure 1-Figure 5As shown, two limit rods 24 are fixedly connected to the upper part of the upper shell 12 of the diaphragm accumulator, and the two limit rods 24 are symmetrically distributed on both sides of the connecting pipe 21. Two limit plates 25 are fixedly connected to the side of the No. 1 connecting plate 23, and the two limit plates 25 are symmetrically distributed on the surface of the No. 1 connecting plate 23. The limit rods 24 are slidably plugged with the limit plates 25. A fixing frame 27 is fixedly connected to the upper part of the upper shell 12 of the diaphragm accumulator, and a No. 2 connecting plate 28 is fixedly connected to the side of the fixing frame 27. A telescopic rod 29 is fixedly connected to the bottom of the No. 2 connecting plate 28, and the telescopic rod 29 is fixedly connected to the upper part of the No. 1 connecting plate 23. A spring 210 is arranged on the surface of the telescopic rod 29, and one end of the spring 210 is fixedly connected to the upper part of the No. 1 connecting plate 23, and the other end of the spring 210 is fixedly connected to the bottom of the No. 2 connecting plate 28.

[0026] Specifically, when the connecting rod 213 pushes the No. 1 connecting plate 23 to move downward, the limit plate 25 will slide along the limit rod 24, and the movement of the No. 1 connecting plate 23 will be limited by the limit rod 24 and the limit plate 25, thereby improving the stability of the No. 1 connecting plate 23 during movement. At the same time, during the upward movement of the No. 1 connecting plate 23, the telescopic rod 29 and the spring 210 are compressed. When the diaphragm body 13 leaks, the internal pressure will decrease, and the telescopic rod 29 and the spring 210 will push the No. 1 connecting plate 23 to move downward, thereby ensuring that the monitoring data of the illuminance meter 218 is accurate.

[0027] Working principle: When the upper shell 12 of the diaphragm accumulator is pressurized, high-pressure gas is stored inside the diaphragm body 13. The pressure between the upper shell 12 and the diaphragm body 13 of the diaphragm accumulator is transmitted to the inside of the piston shell 22 through the connecting pipe 21. At this time, the piston body 212 will be pushed upward, and the connecting rod 213 and the No. 1 connecting plate 23 will move upward, driving the variable resistor plate 214 to move upward along the surface of the sliding variable resistor body 211. When the variable resistor plate 214 moves upward along the sliding variable resistor body 211, the resistance of the entire circuit will decrease. At this time, the brightness of the monitoring bulb 215 will increase. The brightness of the monitoring bulb 215 is monitored by the illuminance measuring instrument 218. When the diaphragm body 13 leaks, the resistance inside the entire circuit will increase, and the brightness of the monitoring bulb 215 will decrease. At this time, the monitoring data of the illuminance measuring instrument 218 will be found to be abnormal.

[0028] When the connecting rod 213 pushes the No. 1 connecting plate 23 to move downward, the limit plate 25 will slide along the limit rod 24, and the movement of the No. 1 connecting plate 23 will be limited by the limit rod 24 and the limit plate 25, thereby improving the stability of the No. 1 connecting plate 23 during movement. At the same time, during the upward movement of the No. 1 connecting plate 23, the telescopic rod 29 and the spring 210 are compressed. When the diaphragm body 13 leaks, the internal pressure will decrease, and the telescopic rod 29 and the spring 210 will push the No. 1 connecting plate 23 to move downward.
