Description

Technical Field

[0001] The utility model relates to the technical field of accumulators, in particular to a stacked low-pressure accumulator. Background Art

[0002] A low-pressure accumulator is an energy storage device in a hydraulic or pneumatic system, mainly used for storing and releasing fluid energy. The accumulator can store energy when the system pressure is low and release it when needed to compensate for the instantaneous pressure fluctuations of the system or supplement the insufficient energy.

[0003] In the installation of existing low-pressure accumulators, a large amount of space will be occupied and the overall installation is not convenient. To solve these problems, a stacked installation method can be adopted. By vertically stacking, the space occupied by the accumulator in the horizontal direction can be greatly reduced, enabling more accumulators to be installed in the same area and improving the energy storage capacity of the system.

[0004] In summary, there is an urgent need for a stacked low-pressure accumulator to solve the above problems. Content of the Utility Model

[0005] In order to overcome the disadvantages that in the installation of low-pressure accumulators, a large amount of space will be occupied and the overall installation is not convenient, the utility model provides a stacked low-pressure accumulator.

[0006] The technical solution of the utility model is as follows: A stacked low-pressure accumulator includes an anti-slip frame, a stacking frame, a housing, an inflation valve, an airbag, a limiting plate, a return spring, a connecting pipe and an electronic valve. The stacking frame is arranged on the anti-slip frame, and a plurality of housings are evenly and spacedly installed on the stacking frame. An inflation valve is installed on each of the plurality of housings. An airbag is connected inside the housing, and the inflation end of the airbag is connected to the inflation valve. A limiting plate is slidably connected to the housing, and a return spring is connected between the limiting plate and the housing. The rear sides of the plurality of housings are interconnected through a connecting pipe, and an electronic valve is installed on the connecting pipe, and the number of electronic valves is the same as the number of housings.

[0007] As a preferred technical solution of the utility model, it further includes a support frame, an ultrasonic detector, a signal transmitting module and a display screen. Three support frames are evenly and spacedly connected to the stacking frame. Three ultrasonic detectors are installed on each of the three support frames. A signal transmitting module is connected to the upper sides of the three support frames. The display screen is installed on the three support frames through screws. The ultrasonic detector, the signal transmitting module and the display screen are electrically connected to each other.

[0008] As a preferred technical solution of the present utility model, it further includes a bracket, a rotating shaft, a reminder board, a baffle plate and a torsion spring. A bracket is connected to the rear side of the anti-slip frame. A plurality of rotating shafts are rotatably connected to the bracket at equal intervals, and the rotating shafts penetrate through the rear side of the housing. The number of the rotating shafts is the same as that of the housing. A reminder board is connected to the rotating shaft, a baffle plate is connected to the rotating shaft, and a torsion spring is connected between the rotating shaft and the bracket.

[0009] As a preferred technical solution of the present utility model, it further includes a sealing ring, and the sealing ring is connected to the limiting plate.

[0010] As a preferred technical solution of the present utility model, it further includes a transparent plate, and transparent plates are arranged on both sides of the anti-slip frame.

[0011] As a preferred technical solution of the present utility model, it further includes a protective shell, and a plurality of protective shells are connected to the bracket at equal intervals.

[0012] The beneficial effects of the present utility model are as follows: 1. By opening the solenoid valve, the pressure oil can flow into the housing from the connecting pipe, connecting the air pump and the inflation valve, so that the airbag is filled with gas at the rated pressure. As the airbag continues to expand, it pushes the limiting plate to move, compressing the return spring. When the pressure oil enters the housing through the connecting pipe, as the pressure inside the housing increases, the volume of the airbag becomes smaller and smaller, which is equivalent to the oil storing energy in the gas inside the airbag.

[0013] 2. By turning on the ultrasonic detector for detection, if there is an air leakage inside the housing, the ultrasonic detector will detect it and display the situation inside the housing on the display screen through the signal transmitting module.

[0014] 3. When the connecting pipe conveys the pressure oil, the pressure oil will contact the baffle plate, prompting the rotating shaft to rotate and driving the reminder board to rotate, so as to prompt the staff to pay attention to the flow state of the pressure oil.

Detailed implementation manners

[0023] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific implementation manners, but does not limit the protection scope and application scope of the present utility model.

[0024] Embodiment 1: A stacked low-pressure accumulator, as Figures 1 - 7 shown, includes an anti-slip rack 1, a stacking rack 2, a housing 3, an inflation valve 4, an airbag 5, a limit plate 6, a return spring 8, a connecting pipe 9 and a solenoid valve 10. A stacking rack 2 for placing low-pressure accumulators is welded on the anti-slip rack 1, and anti-slip patterns are provided at the bottom of the anti-slip rack 1 to provide better grip and stability. A plurality of housings 3 are evenly spaced and installed on the stacking rack 2. An inflation valve 4 is installed on the front side of each of the plurality of housings 3. An airbag 5 is connected inside the housing 3, and the inflation end of the airbag 5 is connected to the inflation valve 4. A limit plate 6 is slidably connected to the rear side of the housing 3, and a return spring 8 is fixedly connected between the limit plate 6 and the housing 3. The rear sides of the plurality of housings 3 are interconnected through a connecting pipe 9, and a solenoid valve 10 is installed on the connecting pipe 9, and the number of solenoid valves 10 is the same as the number of housings 3.

[0025] When energy storage is required, this device can be used. First, the staff opens the solenoid valve 10, and the staff can operate by opening the solenoid valve 10 according to the situation of energy storage required, so that the pressure oil can flow into the housing 3 from the connecting pipe 9. Then, the air pump is connected to the inflation valve 4, and then the inflation valve 4 is opened to fill the airbag 5 with gas at the rated pressure. Thus, using the compressible property of the gas, the airbag 5 will contact the limit plate 6. As the airbag 5 continues to expand, it pushes the limit plate 6 to move, so that the return spring 8 is compressed. Subsequently, when the pressure oil enters the housing 3 through the connecting pipe 9, the airbag 5 is deformed. As the pressure inside the housing 3 increases, the volume of the airbag 5 becomes smaller and smaller, which is equivalent to the oil storing energy in the gas inside the airbag 5. When the external hydraulic system needs oil, the oil in the housing 3 can be quickly discharged, and the volume of the airbag 5 can quickly increase. The airbag 5 transfers the stored energy to the oil, thereby increasing the pressure of the oil in the hydraulic circuit and also enabling the working element to obtain a larger flow rate, so as to achieve reciprocating operation. The accumulator can absorb and supplement energy in the hydraulic system, thereby ensuring the normal pressure of the entire hydraulic system and eliminating pressure fluctuations. And multiple accumulators can better absorb the pressure fluctuations in the system. When the system pressure suddenly drops, multiple accumulators can release energy simultaneously to quickly supplement the system pressure and reduce the amplitude of pressure fluctuations. When energy storage operation is not required, the staff can just close the inflation valve 4 and the solenoid valve 10. The limit plate 6 is reset under the reset action of the return spring 8, and the airbag 5 can separate the gas and the liquid, which is applicable to low-pressure energy storage systems because the capsule material usually performs better under low pressure.

[0026] Embodiment 2: On the basis of Embodiment 1, as Figures 2 - 4 shown, it further includes a support frame 12, an ultrasonic detector 13, a signal transmission module 14 and a display screen 15. Three support frames 12 are fixedly connected to the stacking rack 2 at equal intervals. Three ultrasonic detectors 13 are installed on each of the three support frames 12. A signal transmission module 14 is fixedly connected to the upper sides of the three support frames 12. A display screen 15 is installed on the three support frames 12 by screws. The ultrasonic detector 13, the signal transmission module 14 and the display screen 15 are electrically connected to each other.

[0027] In order to avoid problems such as air leakage caused by damage inside the housing 3, and the staff may not be able to detect these problems immediately. Therefore, the staff can turn on the ultrasonic detector 13 for detection. If there is an air leakage inside the housing 3, the ultrasonic detector 13 will detect it and display the situation inside the housing 3 on the display screen 15 through the signal transmission module 14, so as to remind the staff to repair the accumulator in time.

[0028] As Figures 5 - 7As shown in the figure, it further includes a bracket 16, a rotating shaft 17, a reminder board 18, a baffle 19 and a torsion spring 20. A bracket 16 is fixedly connected to the rear side of the anti-slip bracket 1. A plurality of rotating shafts 17 are rotatably connected to the bracket 16 at equal intervals, and the rotating shafts 17 penetrate through the rear side of the housing 3. The number of the rotating shafts 17 is the same as that of the housing 3. A reminder board 18 is fixedly connected to the rotating shaft 17, a baffle 19 is fixedly connected to the rotating shaft 17, and a torsion spring 20 is connected between the rotating shaft 17 and the bracket 16.

[0029] To prevent the accumulator from malfunctioning during operation due to the staff closing the solenoid valve 10, when the connecting pipe 9 is conveying pressure oil, the pressure oil will contact the baffle 19, causing the rotating shaft 17 to rotate and drive the reminder board 18 to rotate, so as to remind the staff to pay attention to the flow state of the pressure oil. During this process, the torsion spring 20 deforms. When the connecting pipe 9 stops conveying pressure oil, under the reset action of the torsion spring 20, the rotating shaft 17, the reminder board 18 and the baffle 19 will automatically reset.

[0030] As Figures 2 - 4 shown in the figure, it further includes a sealing ring 7, a transparent plate 11 and a protective shell 21. A sealing ring 7 is fixedly connected to the limiting plate 6. Transparent plates 11 are welded on both sides of the anti-slip bracket 1. A plurality of protective shells 21 are fixedly connected to the bracket 16 at equal intervals.

[0031] The sealing ring 7 prevents the low-pressure accumulator from leaking when it is not in operation. The transparent plate 11 facilitates observing whether there is any liquid leakage in the housing 3, and the protective shell 21 wraps the torsion spring 20 to prevent the torsion spring 20 from getting damp and rusty.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
