[0004] The aforementioned patent describes a simple and quick installation method that facilitates the installation of the lightweight wound bladder accumulator body. However, the current equipment has the following problems: without auxiliary support, the installation position of the accumulator may shift, resulting in uneven stress on the seals, which affects the sealing effect, causes leakage, reduces the working efficiency of the accumulator, and may even lead to unstable system pressure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bladder-type accumulator for large-scale lubrication oil stations, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bladder-type accumulator for a large lubricating oil station, comprising a fixed frame and an accumulator, wherein the accumulator is disposed on the inner wall of the fixed frame, and further comprising an installation device; wherein the installation device comprises a docking frame, a hollow block, an installation block, a No. 1 spring, a rotating rod, a support frame, a limiting rod, a Y-shaped frame, an insert rod, a rubber ring, and an L-shaped rod, wherein the docking frame is fixedly installed on the circumferential surface of the accumulator, the hollow block is fixedly installed on the circumferential surface of the fixed frame, the installation block is slidably installed on the inner wall of the hollow block, the rotating rod is rotatably installed on the inner wall of the hollow block, and the support frame is fixedly installed on the rotating rod. The circumferential surface of the rod, the limiting rod is slidably installed on the inner wall of the hollow block, the Y-shaped frame is fixedly installed on the top of the hollow block, the insertion rod is slidably installed on the inner wall of the Y-shaped frame, the rubber ring is set on the circumferential surface of the limiting rod, and the L-shaped rod is fixedly installed on the surface of the mounting block. The docking frame is positioned and installed along the fixed frame, and then rotated 90 degrees so that the docking frame fits against the inner wall of the fixed frame. At this time, the outer wall of the docking frame will contact the inclined surface of the mounting block, so that the mounting block moves and compresses the first spring. When the slot and the mounting block are overlapping, the first spring resets and drives the mounting block to insert into the slot, thus completing the fixing of the accumulator.

[0007] The fixed frame is equipped with a protective device to protect the accumulator and a fire extinguishing device to extinguish a fire caused by accumulator leakage.

[0008] According to the above technical solution, the circumferential surface of the docking frame is provided with a slot, the left side of the mounting block is set as an inclined surface, the first spring is set between the hollow block and the mounting block, and the mounting block is reset by the first spring. The circumferential surface of the rotating rod is provided with a limit groove, and a second spring is set between the limit rod and the hollow block, and the limit rod is reset by the second spring. At this time, the installation of the accumulator can be released, making the operation more convenient, reducing equipment downtime, and improving equipment availability.

[0009] According to the above technical solution, the protective device includes two protective plates and a limit button. The two protective plates are fixedly installed on the surface of the support frame, and the limit button is fixedly installed on the surface of the right protective plate. The circumferential surface of the accumulator is protected by the anti-collision plate.

[0010] According to the above technical solution, the protective device also includes an anti-rotation button and an elastic rod. The anti-rotation button is fixedly installed on the surface of the right protective plate, and the elastic rod is rotatably installed on the surface of the left protective plate. When the rod is rotated upward 180 degrees, the support frame drives the protective plate to move. First, the right protective plate is rotated, and then when the left protective plate is rotated, the elastic rod bends due to contact with the anti-rotation button until it moves between the limit button and the anti-rotation button, and the two protective plates limit each other respectively.

[0011] According to the above technical solution, the protective device further includes a crash plate, a third spring, a connecting frame, an absorber rod, and a fourth spring. The crash plate is slidably installed on the inner wall of the protective plate. The third spring is disposed between the crash plate and the protective plate, and buffering is achieved through the third spring. The connecting frame is fixedly installed on the circumferential surface of the crash plate. One side of the absorber rod is rotatably installed on the surface of the connecting frame, and the other side of the absorber rod is rotatably installed on the surface of the protective plate. The fourth spring is disposed between the absorber rod and the connecting frame, and buffering is achieved through the fourth spring. When the crash plate is impacted, the third spring first absorbs part of the impact force, and the movement of the absorber rod and the fourth spring absorb part of the impact force again.

[0012] According to the above technical solution, the processing device includes an elastic telescopic rod and a sealing plate. The fixed end of the elastic telescopic rod is fixedly installed on the inner wall of the protective plate, and the sealing plate is fixedly installed on the movable end of the elastic telescopic rod. The sealing plate moves downward to seal the protective plate.

[0013] According to the above technical solution, the processing device further includes a brake frame and a triangular block. The brake frame is fixedly installed at the bottom of the sealing plate, and the triangular block is fixedly installed on the surface of the brake frame. The movement of the triangular block drives the brake frame to move.

[0014] According to the above technical solution, the processing device further includes a fixed plate, a fire extinguisher, a switch button, and a sensor. The fixed plate is fixedly installed at the bottom of the sealing plate. The fire extinguisher is located on the inner wall of the fixed plate. The switch button is located at the output port of the fire extinguisher. The sensor is fixedly installed on the outer wall of the fixed plate. A torsion spring is provided between the switch button and the fire extinguisher. The torsion spring drives the switch button to reset. A fuse is provided between the sensor and the switch button. The sensor senses the fire intensity. When a set standard is reached, the fuse breaks due to heat. At this time, the torsion spring is released, causing the switch button to open. The fire extinguisher then extinguishes the fire. The contents of the fire extinguisher fill the sealed area. Through extinguishing the fire in a sealed state, air is effectively isolated, preventing the burning material from obtaining enough oxygen to extinguish the fire, thereby maximizing the protection of the accumulator's integrity.

[0015] This invention provides a bladder-type accumulator for large-scale lubrication oil stations. It has the following beneficial effects:

[0016] (1) The invention, by setting up the installation device, fixes the position of the accumulator by installing it in the fixed frame, which can prevent the accumulator from shifting, shaking or tilting, thereby ensuring the normal operation of the accumulator and the stability of the system. The support frame can provide auxiliary support for the accumulator, improve the stability of the accumulator when it is placed, and make the operation more convenient by quickly installing and removing the accumulator, reducing equipment downtime and improving equipment availability.

[0017] (2) In this invention, by setting up a protective device, when this embodiment is working, the rotating rod is rotated 180 degrees upward without the need for auxiliary support, so that the protective plates on both sides limit each other respectively, so that the position of the protective plates on both sides is accurate during the docking process, avoiding the safety accident caused by the protective plates not being installed correctly or the docking not being firm due to misoperation. After docking is completed, the circumference of the accumulator is protected by the anti-collision plate, and the direct impact force of the anti-collision plate is buffered and decomposed by the No. 3 spring, the absorption rod and the No. 4 spring, so as to avoid the anti-collision plate directly bearing the impact force, causing the outer shell of the accumulator to be deformed or cracked, thereby protecting the internal structure and components of the accumulator from damage.

[0018] (3) This invention, through the setting of the processing device, drives the fire extinguisher to move up and down through the sealing plate and the fixing plate, so that the internal components of the fire extinguisher are fully mixed, thereby improving the fire extinguishing efficiency. In the initial state, the No. 1 torsion spring is in a compressed state. When the accumulator leaks due to an external impact, the sealing plate moves down to seal the protective plate. At this time, the sensor senses the fire. When the set standard is reached, the fuse breaks due to heat. At this time, the No. 1 torsion spring is released and the switch is opened. At this time, the fire extinguisher extinguishes the fire. The internal components of the fire extinguisher will fill the sealed area. Through the fire extinguishing in the sealed state, the air is effectively isolated, so that the burning material does not get enough oxygen and is extinguished, thereby maximizing the protection of the integrity of the accumulator.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-4 One embodiment of the present invention is: a bladder-type accumulator for a large lubricating oil station, comprising a fixed frame 1 and an accumulator 2, the accumulator 2 being disposed on the inner wall of the fixed frame 1, and further comprising an installation device; wherein, the installation device comprises a docking frame 3, a hollow block 4, an installation block 5, a No. 1 spring 6, a rotating rod 7, a support frame 8, a limiting rod 9, a Y-shaped frame 10, an insert rod 11, a rubber ring 12, and an L-shaped rod 13, the docking frame 3 being fixedly installed on the circumferential surface of the accumulator 2, the hollow block 4 being fixedly installed on the circumferential surface of the fixed frame 1, and the installation block 5... The accumulator is slidably installed on the inner wall of the hollow block 4, the rotating rod 7 is rotatably installed on the inner wall of the hollow block 4, the support frame 8 is fixedly installed on the circumferential surface of the rotating rod 7, the limiting rod 9 is slidably installed on the inner wall of the hollow block 4, the Y-shaped frame 10 is fixedly installed on the top of the hollow block 4, the insertion rod 11 is slidably installed on the inner wall of the Y-shaped frame 10, the rubber ring 12 is set on the circumferential surface of the limiting rod 9, and the L-shaped rod 13 is fixedly installed on the surface of the mounting block 5. This can prevent the accumulator from shifting, shaking or tipping over, thereby ensuring the normal operation of the accumulator and the stability of the system.

[0030] The circumferential surface of the docking frame 3 is provided with a slot, the left side of the mounting block 5 is set as an inclined surface, the first spring 6 is set between the hollow block 4 and the mounting block 5, and the mounting block 5 is reset by the first spring 6. The circumferential surface of the rotating rod 7 is provided with a limit groove, and the limit rod 9 is set between the hollow block 4 and the limit rod 9, and the limit rod 9 is reset by the second spring.

[0031] In this embodiment, the accumulator 2 is fixed in position by being installed into the fixed frame 1. During installation, the docking frame 3 is positioned along the fixed frame 1 and then rotated 90 degrees to make the docking frame 3 fit against the inner wall of the fixed frame 1. At this time, the outer wall of the docking frame 3 will contact the inclined surface of the mounting block 5, causing the mounting block 5 to move and compress the first spring 6. When the slot and the mounting block 5 overlap, the first spring 6 returns to its original position and drives the mounting block 5 to insert into the slot. This completes the fixing of the accumulator 2, which can prevent the accumulator from shifting, shaking, or tipping over, thereby ensuring the normal operation of the accumulator and the stability of the system. The support frame 8 can provide auxiliary support for the accumulator 2. When it is necessary to rotate the rotating rod 7, first pull out the insertion rod 11 to release it from the restriction of the limiting rod 9. Then pull out the limiting rod 9 to release it from the limiting groove. Then rotate the rotating rod 7 180 degrees, so that the rotating rod 7 drives the support frame 8 to move. Then rotate the support frame 8 to be perpendicular to the ground. At this time, the fixed frame 1 can be provided with auxiliary support. When the limiting rod 9 moves, it drives the rubber ring 12 to move. The movement of the rubber ring 12 will drive the L-shaped rod 13 to move. The movement of the L-shaped rod 13 will drive the mounting block 5 to move, so that the docking frame 3 is released from the limit of the mounting block 5. At this time, the installation of the accumulator 2 can be released, making the operation more convenient, reducing equipment downtime, and improving the availability of the equipment.

[0032] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a protective device for protecting the accumulator 2 and a fire extinguishing device for extinguishing a fire caused by leakage of the accumulator 2 are provided above the fixing frame 1. The protective device includes two protective plates 20 and a limit button 21. The two protective plates 20 are fixedly installed on the surface of the support frame 8, and the limit button 21 is fixedly installed on the surface of the right protective plate 20. The accumulator 2 is protected by the protective plates 20.

[0033] The protective device also includes an anti-rotation button 23 and an elastic rod 24. The anti-rotation button 23 is fixedly installed on the surface of the right protective plate 20, and the elastic rod 24 is rotatably installed on the surface of the left protective plate 20, so that the two protective plates 20 limit each other respectively. During the docking process, it can ensure that the position of the protective plate 20 is accurate and avoid safety accidents caused by incorrect operation leading to improper installation or loose docking of the protective plate 20.

[0034] The protective device also includes a crash plate 26, a third spring 27, a connecting frame 28, an absorber rod 29, and a fourth spring 210. The crash plate 26 is slidably installed on the inner wall of the protective plate 20. The third spring 27 is located between the crash plate 26 and the protective plate 20, and is used for buffering. The connecting frame 28 is fixedly installed on the circumferential surface of the crash plate 26. One side of the absorber rod 29 is rotatably installed on the surface of the connecting frame 28, and the other side of the absorber rod 29 is rotatably installed on the surface of the protective plate 20. The fourth spring 210 is located between the absorber rod 29 and the connecting frame 28, and is used for buffering to prevent the crash plate 26 from directly bearing the impact force, which could cause the accumulator's outer shell to be deformed or cracked, thus protecting the internal structure and components of the accumulator from damage.

[0035] The treatment device includes an elastic telescopic rod 30 and a sealing plate 31. The fixed end of the elastic telescopic rod 30 is fixedly installed on the inner wall of the protective plate 20, and the sealing plate 31 is fixedly installed on the movable end of the elastic telescopic rod 30. By extinguishing the fire in a sealed state, the air is effectively isolated, so that the burning material does not get enough oxygen and is extinguished, thereby maximizing the protection of the integrity of the accumulator 2.

[0036] The processing device also includes a brake frame 32 and a triangular block 33. The brake frame 32 is fixedly installed at the bottom of the sealing plate 31, and the triangular block 33 is fixedly installed on the surface of the brake frame 32. When the anti-collision plate 26 moves, it will contact the inclined surface of the triangular block 33, causing the triangular block 33 to move downward.

[0037] The processing device also includes a fixed plate 34, a fire extinguisher 35, a switch 36, and a sensor 37. The fixed plate 34 is fixedly installed at the bottom of the sealing plate 31. The fire extinguisher 35 is located on the inner wall of the fixed plate 34. The switch 36 is located at the output port of the fire extinguisher 35. The sensor 37 is fixedly installed on the outer wall of the fixed plate 34. A torsion spring is installed between the switch 36 and the fire extinguisher 35. The torsion spring drives the switch 36 to reset. A fuse is installed between the sensor 37 and the switch 36. When an external impact causes the accumulator 2 to leak, the sealing plate 31 moves downward to seal the protective plate 20. At this time, the sensor 37 senses the fire. When the set standard is reached, the fuse breaks due to heat. The torsion spring is released and the switch 36 is opened, and the fire extinguisher 35 extinguishes the fire.

[0038] In this embodiment, without auxiliary support, the rotating rod 7 is rotated upwards by 180 degrees, causing the support frame 8 to move the protective plate 20. First, the right protective plate 20 is rotated, and then the left protective plate 20 is rotated. The elastic rod 24 bends upon contact with the anti-rotation button 23, until it moves between the limit button 21 and the anti-rotation button 23. The two protective plates 20 then limit each other, ensuring accurate positioning of the protective plates 20 during docking and preventing accidents caused by incorrect installation or insecure docking due to misoperation. After docking, the anti-collision plate 26 is used to stabilize the accumulator 2. The perimeter is protected. When the anti-collision plate 26 is impacted, it moves under force and compresses the third spring 27. First, the third spring 27 absorbs part of the impact force. As the anti-collision plate 26 moves, the connecting frame 28 moves. The connecting frame 28 moves, which in turn moves the absorption rod 29. The movement of the absorption rod 29 compresses the fourth spring 210. Through the movement of the absorption rod 29 and the fourth spring 210, part of the impact force is absorbed again, thus buffering and decomposing the direct impact force on the anti-collision plate 26. This prevents the anti-collision plate 26 from directly bearing the impact force, which could cause the accumulator's outer shell to be deformed or cracked. This protects the internal structure and components of the accumulator from damage.

[0039] When the anti-collision plate 26 moves, it will contact the inclined surface of the triangular block 33, causing the triangular block 33 to move downward. The movement of the triangular block 33 drives the brake frame 32 to move, which in turn drives the sealing plate 31 to move. The movement of the sealing plate 31 will compress the movable end of the elastic telescopic rod 30. At the same time, the movement of the sealing plate 31 drives the fixed plate 34 to move, which in turn drives the fire extinguisher 35 to move, so that the internal components of the fire extinguisher 35 are fully mixed, improving the fire extinguishing efficiency. In the initial state, the first torsion spring is in a compressed state. When the external force impact causes the accumulator 2 to leak, the sealing plate 31 moves downward, sealing the protective plate 20. At this time, the sensor 37 senses the fire. When the set standard is reached, the fuse breaks due to heat. At this time, the first torsion spring is released, and the switch button 36 is opened. At this time, the fire extinguisher 35 extinguishes the fire. The internal components of the fire extinguisher 35 will fill the sealed area. Through the fire extinguishing in the sealed state, the air is effectively isolated, so that the burning material does not get enough oxygen and is extinguished, thus protecting the integrity of the accumulator 2 to the greatest extent.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
