Description

Technical Field

[0001] The invention relates to the technical field of safety protection, and in particular to an energy storage blasting device. Background Art

[0002] Energy storage blasting devices can reduce and avoid the loss of state property and private enterprise property, increase the safety factor of the life and property of enterprise employees, avoid explosion accidents, minimize the economic losses of state-owned enterprises and private enterprises, bring happiness to the families of enterprise employees, and protect the life and property of enterprise personnel.

[0003] In the existing field of energy storage blasting device technology, there is a relatively serious potential risk. The strength membrane used in some energy storage blasting devices may have unstable quality due to factors such as manufacturing process fluctuations, raw material defects or negligence in the quality control link. This quality problem directly leads to the failure of some strength membranes to rupture normally as expected when the internal pressure of the energy storage device rises sharply and exceeds the preset safety threshold. When the strength membrane cannot rupture in time to open the explosion relief channel, the high-pressure environment inside the energy storage device cannot be effectively relieved, and the pressure will continue to accumulate, which undoubtedly greatly increases the possibility of a serious explosion of the energy storage device. Once an explosion occurs, it will cause devastating damage to the surrounding buildings and facilities, have a catastrophic blow to the production and operation of the enterprise, and cause huge losses to a large number of state-owned assets and private enterprise properties. More seriously, it will pose a direct and huge threat to the life safety of enterprise employees, may cause irreversible casualties, and bring endless pain and disaster to many families. In order to avoid the above situation, the energy storage blasting device is redesigned here. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose an energy storage blasting device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The energy storage blasting device comprises a protective cover and a strength membrane, wherein the protective cover is provided with a movable groove, a screw is provided in the movable groove through a support plate, a piston plate is threadedly mounted on the screw, the piston plate is sealingly and slidably arranged in the movable groove through a first limiting mechanism, the piston plate is also arranged in the movable groove through a first elastic mechanism, a movable frame is threadedly mounted on the screw, a second limiting mechanism corresponding to the movable frame is mounted on the protective cover, a fixed sleeve is fixedly arranged on the movable frame, a poking pin corresponding to the strength membrane is provided on the movable frame and the movable frame and the fixed sleeve are rotated together, a supporting frame is mounted on the movable frame, the supporting frame is connected with the poking pin through a transmission mechanism, a rack frame is provided on the protective cover, the supporting frame is connected with the rack frame through a rotating mechanism, a reminding groove is also provided on the protective cover, a connecting frame connected with the piston plate is provided in the reminding groove, an extrusion groove is provided on the connecting frame, a sliding rod is provided in the extrusion groove, and a limiting frame extending to the outside of the connecting frame is provided on the sliding rod through a second elastic mechanism sliding sleeve.

[0006] Preferably, the first limiting mechanism comprises a limiting block mounted on the piston plate, and a limiting groove corresponding to the limiting block is provided on the inner wall of the movable groove.

[0007] Preferably, the first elastic mechanism comprises a first spring which is arranged in the movable groove and sleeved on the outside of the screw rod, and two ends of the first spring are respectively connected to the outer wall of the piston plate and the inner wall of the movable groove.

[0008] Preferably, the second limiting mechanism comprises a limiting rod mounted on the protective cover, and the limiting rod slides through the movable frame.

[0009] Preferably, the transmission mechanism comprises a driving gear mounted on the support frame, and a transmission gear connected to the puncture needle is provided on the movable frame, and the driving gear is meshed with the transmission gear.

[0010] Preferably, the rotating mechanism comprises a rotating gear mounted on a supporting frame, and the rotating gear is meshed with a rack frame.

[0011] Preferably, the second elastic mechanism comprises a second spring sleeved on the outside of the slide rod, and two ends of the second spring are respectively connected to the inner wall of the extrusion groove and the outer wall of the limiting frame.

[0012] Preferably, the driving gear and the transmission gear are both bevel gears and the meshing relationship between them is vertical meshing, and the rotating gear is a circular gear.

[0013] Beneficial effects of the present invention: 1. Under normal circumstances, the strength membrane itself ruptures when the internal pressure of the equipment increases to the set value to achieve explosion relief, ensure the safety of the energy storage device, and maintain the effectiveness of the traditional explosion relief mechanism. When the strength membrane cannot be ruptured normally due to quality problems, the device can automatically start the backup puncture mechanism. The piston plate is driven by pressure to move, and the puncture needle is driven through a series of transmissions to puncture the strength membrane in a rotary feed manner, ensuring that the explosion can still be effectively vented in the event of strength membrane failure, greatly improving the reliability of the explosion relief of the entire energy storage blasting device and reducing the risk of energy storage equipment bursting due to strength membrane failure.

[0014] 2. When the strength film fails to rupture normally and the backup puncture mechanism is triggered, the piston plate drives the connecting frame to move. After the connecting frame extends out of the reminder slot, the limit frame pops up under the action of the second spring, making it impossible for the connecting frame to return to its original position. The leaked part can visually warn the operator that there is a quality problem with the strength film, making it convenient for the operator to conduct quality inspection, replacement or take other maintenance measures on the strength film in a timely manner, which helps to improve the timeliness and accuracy of the operation and maintenance of the energy storage device and ensure the long-term stable operation of the energy storage system.

[0015] 3. The overall structural design is ingenious. For example, the transmission mechanism uses bevel gears (driving gear and transmission gear) to achieve vertical meshing, effectively transmitting power in a limited space, so that the needle can complete complex movements under the coordinated action of the movable frame and other components, which not only ensures the function but also saves space.

[0016] 4. The layout of each component is reasonable. For example, the protective cover is integrated with movable slots, reminder slots and structures required for installing various mechanisms, making the entire device compact and easy to install and arrange in the energy storage device system, suitable for a variety of different energy storage device application scenarios.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-5 In modern industrial environments, the safety of energy storage equipment is of vital importance, and the energy storage blasting device, as a key component to ensure its safe operation, is receiving more and more attention. With its unique structural design, this energy storage blasting device is designed to effectively deal with possible quality problems of the strength membrane 2 and ensure that the energy storage equipment can maintain a safe and stable operating state under various working conditions.

[0021] As the external protective structure of the device, the protective cover 1 not only provides physical protection for the internal components, but its design is also closely related to the function of the entire device. The movable groove 3 on the protective cover 1 provides a spatial basis for the movement of the piston plate 5 and related components.

[0022] The screw rod 4 is installed in the movable groove 3 through a carefully designed support plate 11. This installation method ensures that the screw rod 4 can remain stable when subjected to various forces without displacement or shaking, thereby providing reliable support for the subsequent precise movement of the piston plate 5 and the movable frame 10.

[0023] The piston plate 5 plays a critical role in the device. It realizes sealed sliding cooperation with the movable groove 3 through the first limiting mechanism. The limiting block 7 in the first limiting mechanism cooperates with the limiting groove 8 on the inner wall of the movable groove 3 to form a precise and stable limiting mechanism. The limiting block 7 in the limiting groove 8 can not only limit the range of motion of the piston plate 5 to ensure that it slides in the movable groove 3 according to the predetermined trajectory, but also its sealed sliding characteristics effectively prevent the leakage of gas or liquid medium in the movable groove 3, which is crucial to maintain the stability of the pressure environment inside the device.

[0024] For example, when the internal pressure of the energy storage device changes, if leakage occurs at the piston plate 5, it will cause inaccurate pressure measurement, thereby affecting the judgment and response of the entire device to the pressure state of the energy storage device.

[0025] The first elastic mechanism provides the initial stabilizing force and subsequent driving force for the piston plate 5. The first spring 6, which is sleeved on the outside of the screw rod 4 and whose two ends are respectively connected to the outer wall of the piston plate 5 and the inner wall of the movable groove 3, relies on its elastic potential energy to stably maintain the piston plate 5 in the initial position in the movable groove 3 when the device is not subjected to abnormal pressure. This design makes the device have higher stability and reliability in normal operation and reduces the possibility of malfunction.

[0026] When the internal pressure of the energy storage device fluctuates normally, the first spring 6 can absorb these tiny pressure changes and keep the piston plate 5 still. Only when the pressure exceeds a certain threshold and the strength membrane 2 fails to rupture normally, the piston plate 5 will overcome the elastic force of the first spring 6 and start to move.

[0027] The threaded connection between the movable frame 10 and the screw rod 4 realizes the motion transmission and conversion between the two. When the screw rod 4 rotates due to the movement of the piston plate 5, the movable frame 10 performs linear motion on the screw rod 4.

[0028] In order to ensure the movement direction and stability of the movable frame 10, the second limiting mechanism installed on the protective cover 1 plays an important role. The limiting rod 12 slides through the movable frame 10, effectively limiting the rotation of the movable frame 10, so that it can only move linearly along the axial direction of the screw 4. This design avoids the connection failure or movement interference of the movable frame 10 with other components due to its own rotation during the movement process, and ensures the accuracy and reliability of the internal transmission of the entire device.

[0029] The fixed sleeve 18 and the movable frame 10 jointly carry and support the puncture needle 19 and provide necessary conditions for the rotation of the puncture needle 19. The relative position and movement mode of the puncture needle 19 with the strength film 2 as a key film-breaking component directly determine whether the strength film 2 can be successfully punctured. When the movable frame 10 moves, the puncture needle 19 approaches the strength film 2. At the same time, the transmission mechanism enables the puncture needle 19 to approach the strength film 2 in a rotational feeding manner, which greatly improves the success rate and efficiency of puncturing the strength film 2.

[0030] The driving gear 22 and the transmission gear 20 in the transmission mechanism adopt a bevel gear design and realize vertical meshing. This design cleverly realizes the effective transmission of power and the conversion of direction in a limited space. The driving gear 22 is installed on the support frame 21. When the support frame 21 rotates, the driving gear 22 rotates accordingly, and drives the puncture needle 19 to rotate through the meshing with the transmission gear 20, so that the puncture needle 19 rotates at the same time when approaching the strength film 2, like a precise micro drill, which can more easily break through the surface of the strength film 2, even if the strength film 2 has increased toughness or surface hardening due to quality problems, it can also effectively puncture it.

[0031] The structural design of the support frame 21 is ingenious. It consists of a horizontal plate and a vertical rotating rod, and the rotating rod is rotatably connected to the horizontal plate. This structure makes it possible for the rotating mechanism and the transmission mechanism to work together. The rotating gear 23 in the rotating mechanism is installed on the support frame 21. When the movable frame 10 drives the support frame 21 to move, the rotating gear 23 and the rack frame 24 move relative to each other and mesh. The rack frame 24 is fixed on the protective cover 1, and its toothed structure cooperates with the rotating gear 23, so that the rotating gear 23 rotates during the movement, thereby driving the rotating rod part of the support frame 21 to rotate. This design converts the linear motion of the movable frame 10 into the rotational motion of the support frame 21, thereby realizing the rotation of the active gear 22, and finally driving the puncture needle 19 to approach the strength membrane 2 in a rotational feeding manner, forming a complete and ingenious mechanical transmission chain, ensuring that the strength membrane 2 can be punctured in a timely and effective manner when the quality is abnormal, releasing the pressure inside the energy storage device, and avoiding the occurrence of danger.

[0032] In addition, the device also has a warning function. When the piston plate 5 moves due to abnormal pressure, the connecting frame 9 connected thereto also moves. After the connecting frame 9 partially moves out of the warning groove 13, the limiting frame 16, which was originally squeezed and limited by the inner wall of the warning groove 13, is squeezed out under the action of the second spring 17. The second spring 17 is sleeved on the outside of the slide rod 15, and its two ends are respectively connected to the inner wall of the extrusion groove 14 and the outer wall of the limiting frame 16, providing a stable squeezing force for the limiting frame 16.

[0033] After the limit frame 16 is extended, the leaked part of the connection frame 9 will play an obvious warning role. During the inspection or daily maintenance process, the operator can quickly learn that the strength membrane 2 may have quality problems by observing this warning information. This warning function not only helps to timely discover the quality risks of the strength membrane 2, but also provides clear instructions for subsequent quality inspections and equipment maintenance, so that the operator can conduct targeted quality inspections on the purchased strength membrane 2 and other operations, thereby ensuring the reliability and safety of the energy storage blasting device from the source.

[0034] For example, operators can sample and test the strength membrane 2 of the same batch according to the warning information to check whether there are defects in its material properties, thickness uniformity, manufacturing process, etc., so as to timely adjust the procurement strategy or require suppliers to improve product quality, avoid a series of safety accidents and equipment failures caused by quality problems of the strength membrane 2, reduce the operating risks and maintenance costs of energy storage equipment, and improve the stability and reliability of the entire energy storage system. In summary, the energy storage blasting device maintains stability when the strength membrane 2 ruptures normally through the close cooperation and coordinated work between the various components, and can quickly start the auxiliary membrane rupture mechanism when the quality of the strength membrane 2 is abnormal, and issue warning information in time, providing all-round protection for the safe operation of energy storage equipment, and has extremely high application value and broad market prospects in the construction, energy storage and other industries.

[0035] When the present invention is used, the protective cover 1 is installed on the equipment. When the internal pressure of the equipment increases, the strength film 2 may be broken. This is when the quality of the strength film 2 is normal. In this case, the piston plate 5 will not move in the movable groove 3 and compress the first spring 6. If the strength film 2 has quality problems and cannot be broken, the pressure will enter the movable groove 3 and squeeze the piston plate 5, so that the piston plate 5 compresses the first spring 6 and moves. Since the piston plate 5 is threadedly installed on the screw 4, the screw 4 will rotate. When the screw 4 rotates, it first drives the movable frame 10 to move. The movement of the movable frame 10 can drive the fixed sleeve 18, the puncture needle 19 and the rotating gear 23 to move. The rotating gear 23 can rotate under the action of the rack frame 24 to drive the rotating rod part of the support frame 21 to rotate, thereby realizing the synchronous rotation of the driving gear 22. The driving gear 22 can drive the puncture needle 19 to rotate with the help of the transmission gear 20, so the puncture needle 19 will approach the strength film 2 in a rotational feeding manner and can puncture the strength film 2.

[0036] At the same time, when the piston plate 5 moves, it can also drive the connecting frame 9 to move. Part of the connecting frame 9 will move out of the reminder groove 13. When the limit frame 16 loses the extrusion limit of the inner wall of the reminder groove 13, it will be squeezed out under the action of the second spring 17. At this time, the connecting frame 9 can no longer return to the reminder groove 13. The leaked part of the connecting frame 9 serves as a warning. The operator can know that there is a problem with the quality of the strength membrane 2 through the warning, and thus perform quality inspection and other operations on the purchased strength membrane 2.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
