Description

Technical Field

[0001] This utility model relates to energy storage technology, specifically an energy storage device with a pressure alarm function. Background Art

[0002] An accumulator is an energy storage device in a hydraulic or pneumatic system. It converts the system's energy into compressed or potential energy at appropriate times and stores it. When the system needs it, it releases the compressed or potential energy back into hydraulic or pneumatic energy to replenish the system. When the system pressure increases instantaneously, it can absorb this energy to ensure the overall system pressure remains normal.

[0003] Existing accumulators generally consist of a cylinder, an air filling valve, a liquid inlet valve, and an energy storage structure. The energy storage mechanism can be a piston or an air bladder. Therefore, it is impossible to measure the internal pressure of the accumulator during use, making it difficult for operators to grasp the internal air pressure. This results in an inability to react in time when the accumulator leaks, hindering the staff from observing and repairing it promptly. Moreover, when the pressure inside the accumulator is too high, it cannot be depressurized in time, causing the accumulator's service life to be shortened or even damaged. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides an accumulator with a pressure alarm function, which can detect the air pressure of the airbag, allowing operators to observe and understand the internal air pressure of the accumulator in real time, facilitating the operator's judgment of the accumulator's working status. Moreover, the alarm component can remind the operator that the liquid pressure inside the accumulator is too high, making it convenient for the operator to open the pressure relief valve to release the pressure.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: an accumulator with a pressure alarm function, comprising a tank, an inflation pipe, and a liquid inlet valve. An air bladder is located at the top of the tank. The inflation pipe is located at the top of the tank and communicates with the air bladder. The liquid inlet valve is located at the bottom of the tank. The accumulator also includes an alarm tank. A buzzer is located at the top of the alarm tank, and a connecting pipe is located at the bottom of the alarm tank, communicating with the tank. An alarm unit is located inside the alarm tank, and the alarm unit is used to control the working state of the buzzer.

[0006] Preferably, an inflation valve is provided at the top of the inflation tube, and a pressure gauge is provided in the middle of the inflation tube.

[0007] Preferably, a pressure relief valve is provided on one side of the bottom of the tank.

[0008] Preferably, the alarm tank has a partition in the middle, which divides the alarm tank into a liquid chamber and a telescopic chamber, and the liquid chamber is connected to a connecting pipe.

[0009] Preferably, the alarm unit includes a piston and a guide post. The piston is located in the liquid chamber. The bottom end of the guide post is fixed to the center of the piston. The top end of the guide post passes through a partition and is provided with a top block. The top block is located in the telescopic cavity. A switch is provided at the top of the telescopic cavity. The top block presses the switch to control the buzzer to turn on.

[0010] Preferably, the guide post is fitted with a spring, which is located between the top block and the partition plate.

[0011] In summary, this utility model achieves the following technical effects:

[0012] This utility model discloses an accumulator with a pressure alarm function. It uses a pressure gauge to detect the air pressure of the air bladder, allowing the operator to observe and understand the internal air pressure of the accumulator in real time. This facilitates the operator to indirectly judge the hydraulic pressure in the accumulator. In addition, with the alarm component, when the liquid pressure in the accumulator is too high, a buzzer alarm will sound to remind the operator to open the pressure relief valve in time to release the pressure.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0023] Example 1:

[0024] like Figure 1As shown in Figure 2, an accumulator with a pressure alarm function includes a tank 1, an inflation pipe 3, and an inlet valve 2. An air bladder 7 is located at the top of the tank 1. The inflation pipe 3 is located at the top of the tank 1 and communicates with the air bladder 7. The inlet valve 2 is located at the bottom of the tank 1. The accumulator also includes an alarm tank 8. A buzzer 16 is located at the top of the alarm tank 8, and a connecting pipe 11 is located at the bottom of the alarm tank 8, communicating with the tank 1. An alarm unit is located inside the alarm tank 8, which controls the working state of the buzzer 16. An inflation valve 4 is located at the top of the inflation pipe 3, and a pressure gauge 6 is located in the middle of the inflation pipe 3. A pressure relief valve 5 is located on one side of the bottom of the tank 1.

[0025] The accumulator with pressure alarm function in this embodiment uses pressure gauge 6 to detect the air pressure of airbag 7, so that the operator can observe and understand the internal air pressure of the accumulator in real time, which makes it easier for the operator to indirectly judge the hydraulic pressure in the accumulator.

[0026] like Figure 3 As shown, the top of the alarm tank 8 is fixed to the tank body 1 by a clamp 9. A partition 10 is provided in the middle of the alarm tank 8, which divides the alarm tank 8 into a liquid chamber and a telescopic chamber. The liquid chamber is connected to the connecting pipe 11. The alarm unit includes a piston 12 and a guide post 13. The piston 12 is located in the liquid chamber. The bottom end of the guide post 13 is fixed to the center of the piston 12. The top end of the guide post 13 passes through the partition 10 and is provided with a top block 14. The top block 14 is located in the telescopic chamber. A switch 15 is provided at the top of the telescopic chamber. The top block 14 presses the switch 15 to control the buzzer 16 to be turned on. A spring 17 is sleeved on the guide post 13. The spring 17 is located between the top block 14 and the partition 10.

[0027] When the liquid pressure in the accumulator increases, the alarm component transmits the signal to the liquid chamber, causing the piston 12 to move upward. The guide post 13 drives the top block 14 to rise until the top block 14 blocks the switch 15. The buzzer 16 then sounds an alarm to remind the operator that the liquid pressure in the accumulator is too high, prompting the operator to open the pressure relief valve 5 to release the pressure. When the liquid pressure in the accumulator decreases, the piston 12 is pushed down and reset by the spring 17.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
