Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, and particularly relates to a device that converts instantaneous mechanical impact into electric energy.

Background Art

[0002] Fire extinguishing devices are common fire prevention facilities. The fire extinguishing devices are filled with fire extinguishing agents for fire extinguishing, such as carbon dioxide fire extinguishing agent, heptafluoropropane fire extinguishing agent, hexafluoropropane fire extinguishing agent, perfluorohexanone fire extinguishing agent, etc. At present, fire extinguishing devices need to be configured for various battery clusters / cabinets to ensure timely fire extinguishing in case of a fire and avoid greater losses caused by the spread of the fire.

[0003] Since various battery clusters / cabinets are usually unattended, in order to facilitate automatic fire extinguishing when a fire occurs, fire extinguishing devices with self-starting functions have emerged, such as a fixed temperature-sensing self-starting fire extinguishing device disclosed in the Chinese utility model patent with the application number CN201921303683.2. However, in existing self-starting fire extinguishing devices, a thermal-sensitive wire is generally arranged inside the cabinet. When a fire occurs, the thermal-sensitive wire will be ignited, and the ignited thermal-sensitive wire is used to trigger the fire extinguishing device to spray the fire extinguishing agent (or trigger the suppression device to spray the suppression agent). However, the ignition temperature of the thermal-sensitive wire usually reaches 170°, and it cannot be ignited in the initial stage of a fire. Therefore, how to enable the self-starting fire extinguishing device to be triggered in the initial stage of a fire (i.e., the thermal runaway occurrence period) is an urgent problem to be solved.

A gravity block is arranged at the lower end of the driving gravity pawl, and the lower end of the driving gravity pawl is inserted into the tooth gap of the ratchet body in the standby state.

[0009] Further, the ratchet mechanism further includes a driven check pawl and a reset assembly.

[0010] A connecting plate is downwardly extended at the end of one end of the control lever, and the upper end of the driving gravity pawl is rotatably connected to one end of the connecting plate away from the ratchet body through a first connecting shaft.

[0012] Further, the ratchet mechanism further includes a first limiting member for limiting the driving gravity pawl to disengage the driving gravity pawl from the ratchet body. The first limiting member is connected to the end of one end of the control lever, and the first limiting member is located on one side of the upper end of the driving gravity pawl close to the ratchet body.

[0013] Further, the ratchet mechanism further includes a second limiting member for limiting the control lever so that the control lever does not touch the ratchet body. The second limiting member is fixed inside the housing body, and the second limiting member is located on one side of the ratchet body away from the driving gravity pawl.

[0014] Further, the ratchet mechanism further includes a support member and a second spring.

[0015] The support member is arranged inside the housing body and is located at a position close to the free end of the control lever. The control lever is supported on the support member; the upper end of the second spring is connected to the control lever, and the lower end of the second spring is connected to the housing body.

[0016] Further, the electric energy converter is a piezoelectric ceramic.

[0017] Further, the towing rope is a steel wire rope.

Detailed implementation manners

[0041] To better understand the technical solution of the present utility model, the technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0042] Here, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing these embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0043] Please refer to Figures 1 to 6 As shown, a device of the present utility model for converting instantaneous mechanical impact into electric energy includes an electric energy converter 1, a striking device 2, a ratchet mechanism 3, a towing rope 4, a first spring 5, and a housing 6. Among them, the electric energy converter 1 is used to convert instantaneous mechanical impact into electric energy, the striking device 2 is used to strike the electric energy converter 1, and the ratchet mechanism 3 is used to control whether the striking device 2 strikes the electric energy converter 1.

[0044] A trigger cylinder 7 is provided on the housing 6. One end of the electric energy converter 1 is arranged inside the trigger cylinder 7, the other end of the first spring 5 is arranged inside the trigger cylinder 7, and the striking device 2 is movably arranged in the middle inside the trigger cylinder 7 so that the striking device 2 can move inside the trigger cylinder 7.

[0045] The ratchet mechanism 3 is arranged inside the housing 6 and is located at one end close to the first spring 5. One end of the towing rope 4 is connected to the striking device 2, and the other end of the towing rope 4 is wound around the ratchet mechanism 3 and tow the striking device 2 to compress the first spring 5 for energy storage. When the ratchet mechanism 3 releases the towing rope 4, the striking device 2 strikes the electric energy converter 1 under the action of the first spring 5, so that the electric energy converter 1 converts instantaneous mechanical impact into electric energy, and the instantaneous current generated by the electric energy converter 1 is used to trigger the triggering wire of the self-starting fire extinguishing device. In the specific implementation of the present utility model, when the instantaneous current generated by the electric energy converter 1 triggers the triggering wire of the self-starting fire extinguishing device, the triggering wire will activate the initiator inside the self-starting fire extinguishing device to ignite the generating agent, and the generating agent generates a large amount of gas through the combustion reaction to push the fire extinguishing agent to be released to achieve fire extinguishing.

[0046] The utility model sets a trigger cylinder 7 on the outer shell 6, sets an electric energy converter 1 at one end of the trigger cylinder 7, sets a first spring 5 at the other end of the trigger cylinder 7, and movably sets a striking device 2 in the middle of the trigger cylinder 7. At the same time, a ratchet mechanism 3 is used to drive a traction rope 4 to traction the striking device 2 to compress the first spring 5 for energy storage, so that when the ratchet mechanism 3 releases the traction rope 4, the striking device 2 can strike the electric energy converter 1 under the action of the first spring 5, and the electric energy converter 1 can convert the instantaneous mechanical impact into electric energy. Therefore, by adopting the device of the utility model, the instantaneous current generated by the electric energy converter 1 can be reliably used to trigger the triggering wire of the self-starting fire extinguishing device, so that the self-starting fire extinguishing device can be triggered to release the fire extinguishing agent at the initial stage of a fire (i.e., the heat runaway occurrence stage), which is beneficial to controlling the fire situation at the initial stage of a fire and reducing the losses caused by the fire.

[0047] In some embodiments of the present utility model, the ratchet mechanism 3 includes a ratchet body 31, a driving gravity pawl 32 and a control lever 33; the other end of the traction rope 4 is connected and wound around the ratchet body 31;

[0048] A first fixed shaft 61 is arranged in the outer shell 6, and the ratchet body 31 is rotatably arranged on the first fixed shaft 61; a second fixed shaft 62 is arranged above the ratchet body 31 in the outer shell 6. The middle of one end of the control lever 33 is rotatably connected to the second fixed shaft 62, and the other end of the control lever 33 extends to the outside of the outer shell 6 to facilitate operating the control lever 33 to rotate around the second fixed shaft 62; the driving gravity pawl 32 is located between the ratchet body 31 and the trigger cylinder 7, and the upper end of the driving gravity pawl 32 is rotatably connected to the end of one end of the control lever 33. A gravity block 321 is arranged at the lower end of the driving gravity pawl 32, and the lower end of the driving gravity pawl 32 is inserted into the tooth gap 311 of the ratchet body 31 in the standby state, so that the ratchet body 31 cannot rotate in the standby state. When the present utility model is specifically implemented, the lower end of the driving gravity pawl 32 is connected to the middle of the gravity block 321. The gravity block 321 forms a first tooth 322 at the end close to the ratchet body 31 (i.e., the left side), and the weight on the right side of the gravity block 321 is greater than the weight on the left side. In this way, the whole driving gravity pawl 32 will tilt to the left under the action of gravity, which can effectively ensure that without operating the control lever 33, the driving gravity pawl 32 will automatically reset to the left and the first tooth 322 of the gravity block 321 will clamp the ratchet body 31, so that the ratchet body 31 will not rotate; and when operating the control lever 33 to drive the first tooth 322 of the driving gravity pawl 32 to disengage from the ratchet body 31, the ratchet body 31 can rotate to release the traction rope 4, so that the striking device 2 can strike the electric energy converter 1 under the action of the first spring 5.

[0049] Furthermore, the ratchet mechanism 3 further includes a driven check pawl 34 and a reset assembly 35;

[0050] One end of the control lever 33 extends downward to form a connecting plate 331. The upper end of the active gravity pawl 32 is rotatably connected to one end of the connecting plate 331 away from the ratchet body 31 through a first connecting shaft 323, enabling the entire active gravity pawl 32 to rotate around the first connecting shaft 323 as the rotation center;

[0051] The connecting plate 331 is rotatably provided with a second connecting shaft 332 at one end close to the ratchet body 31. The upper end of the driven check pawl 34 is connected to the second connecting shaft 332 through a reset assembly 35. The lower end of the driven check pawl 34 is inserted into the tooth gap 311 of the ratchet body 31 in the standby state. In the specific implementation of the present invention, the driven check pawl 34 is formed with a second tooth 341 at one end close to the ratchet body 31, so that the second tooth 341 can be inserted into the tooth gap 311 of the ratchet body 31 in the standby state.

[0052] By designing the ratchet mechanism 3 to include a ratchet body 31, an active gravity pawl 32, a control lever 33, and a driven check pawl 34, the present invention connects both the active gravity pawl 32 and the driven check pawl 34 to the connecting plate 331 at one end of the control lever 33, and makes both the active gravity pawl 32 and the driven check pawl 34 inserted into the tooth gap 311 of the ratchet body 31 in the standby state. In specific use, on the one hand, the active gravity pawl 32 can use its own gravity to drive the first tooth 322 to firmly clamp the ratchet body 31 in the standby state, ensuring that the ratchet body 31 will not rotate. At the same time, the active gravity pawl 32 can automatically reset under the action of gravity after being released. On the other hand, the setting of the driven check pawl 34 can effectively prevent the ratchet body 31 from slipping when the active gravity pawl 32 moves. At the same time, the driven check pawl 34 is equipped with a reset assembly 35. After both the driven check pawl 34 and the active gravity pawl 32 are disengaged from the ratchet body 31, the driven check pawl 34 can be reset by means of the reset assembly 35.

[0053] As a specific implementation manner of the present invention, please refer to Figure 5As shown, the reset assembly 35 includes a third spring 351, a reset operating member 352, and a plugging cover 353. The second connecting shaft 332 is a hollow shaft, and one end of the second connecting shaft 332 is fixedly connected to the driven check ratchet 34. The other end of the second connecting shaft 332 passes through the connecting plate 331 and is threadedly connected to the plugging cover 353, so that the driven check ratchet 34 can rotate relative to the connecting plate 331. The reset operating member 352 has an assembling portion 3521 movably assembled inside the second connecting shaft 332 and an operating rod portion 3522 extending outside the plugging cover 353. A spring assembling cavity 3523 is formed at one end of the assembling portion 3521 facing the driven check ratchet 34. The third spring 351 is installed inside the second connecting shaft 332. One end of the third spring 351 abuts against the driven check ratchet 34, and the other end abuts against the closed end of the spring assembling cavity 3523. A positioning key 3524 is provided on the outer wall of the assembling portion 3521, and a positioning groove 3321 matching the positioning key 3524 is provided on the inner wall of the second connecting shaft 332. When the reset assembly 35 of the present utility model is specifically used, under normal circumstances, the positioning key 3524 will disengage from the positioning groove 3321. When it is necessary to reset the driven check ratchet 34, the reset operating member 352 needs to be pressed inward through the operating rod portion 3522, so that the positioning key 3524 of the assembling portion 3521 is snapped into the positioning groove 3321. At this time, the reset operating member 352 can be rotated to drive the driven check ratchet 34 to rotate to achieve reset. After the reset is completed, only the operating rod portion 3522 needs to be released, and the positioning key 3524 will automatically disengage from the positioning groove 3321 under the action of the third spring 351.

[0054] Furthermore, the ratchet mechanism 3 further includes a first limiting member 36 for limiting the active gravity ratchet 32 to disengage the active gravity ratchet 32 from the ratchet body 31. The first limiting member 36 is connected to one end of the operating lever 33, and the first limiting member 36 is located on one side of the upper end of the active gravity ratchet 32 close to the ratchet body 31. When the ratchet mechanism 3 is specifically used, when the operating lever 33 is rotated downward, the active gravity ratchet 32 will be pushed outwards under the limiting action of the first limiting member 36, so that the active gravity ratchet 32 is disengaged from the ratchet body 31. When the operating lever 33 is rotated upward, the active gravity ratchet 32 will be disengaged from the restriction of the first limiting member 36 and re-inserted into the tooth gap 311 of the ratchet body 31 under the action of its own gravity.

[0055] Furthermore, the ratchet mechanism 3 further includes a second limiting member 37 for limiting the operating lever 33 so that the operating lever 33 does not touch the ratchet body 31. The second limiting member 37 is fixed inside the outer housing 6, and the second limiting member 37 is located on the side of the ratchet body 31 away from the active gravity ratchet 32.

[0056] In the present utility model, a second limiting member 37 is provided on one side of the ratchet body 31 away from the active gravity pawl 32, so that when the operating lever 33 rotates downward, the second limiting member 37 can be used to limit the operating lever 33, ensuring that the operating lever 33 does not touch the ratchet body 31.

[0057] In some embodiments of the present utility model, the ratchet mechanism 3 further includes a support member 38 and a second spring 39;

[0058] The support member 38 is arranged in the outer housing 6 and is located near the free end of the operating lever 33, and the operating lever 33 is supported on the support member 38; the upper end of the second spring 39 is connected to the operating lever 38, and the lower end of the second spring 39 is connected to the outer housing 6. When the operating lever 33 loses the support of the support member 38, the operating lever 33 can quickly rotate downward under the pulling of the second spring 39, so as to drive both the driven check pawl 34 and the active gravity pawl 32 to disengage from the ratchet body 31; and when the operating lever 33 is supported on the support member 38, both the driven check pawl 34 and the active gravity pawl 32 are inserted into the tooth gaps 311 of the ratchet body 31.

[0059] As a specific implementation manner of the present utility model, in order to ensure the power conversion effect, the power converter 1 is a piezoelectric ceramic. The most prominent characteristic of piezoelectric ceramics is piezoelectricity, including direct piezoelectricity and inverse piezoelectricity; direct piezoelectricity means that when some dielectrics are under mechanical external force, the positive and negative charge centers inside the dielectric undergo relative displacement, causing polarization, and thus bound charges with opposite signs appear on the two end surfaces of the dielectric; at the same time, piezoelectric ceramics also have a sensitive characteristic and can convert extremely weak mechanical vibrations into electrical signals.

[0060] As a specific implementation manner of the present utility model, in order to ensure that the traction rope 4 is not easily damaged during use, the traction rope 4 is a steel wire rope.

[0061] As a specific implementation manner of the present utility model, in order to better achieve energy storage, the first spring 5 is a strong spring. When the present utility model is specifically implemented, when the ratchet mechanism 3 pulls the striking device 2 through the traction rope 4 to be in an energy storage state, the first spring 5 is tightened to the limiting position, so that the first spring 5 is in the maximum energy state. In this way, when the ratchet mechanism 3 releases the traction rope 4, the striking device 2 can reliably strike the power converter 1 and generate a strong instantaneous current.

[0062] In an embodiment of the present utility model, the device further includes a magnetic attraction block 8, and the magnetic attraction block 8 is arranged on the outer surface of the outer housing 6. By arranging the magnetic attraction block 8 on the outer surface of the outer housing 6, the whole device can be installed on various cabinets by means of magnetic attraction during specific use, which is more convenient for installation and use. Of course, the present utility model is not limited to this, and other installation methods can also be adopted to install the whole device on various cabinets during specific implementation.

[0063] As a specific implementation manner of the present utility model, the outer housing 6 adopts a square housing.

[0064] The overall working principle of the device of the present utility model is as follows: Please refer to Figures 2 - 4 As shown, when in the standby state, the active gravity pawl 32 and the driven check pawl 34 of the ratchet mechanism 3 are both inserted into the tooth gaps 311 of the ratchet body 31. At this time, the ratchet mechanism 3 drives the traction rope 4 to pull the striking device 2 to compress the first spring 5 for energy storage. When the operating lever 33 is rotated to the lower limit position, the operating lever 33 can drive the active gravity pawl 32 and the driven check pawl 34 to be in a released state, that is, the active gravity pawl 32 and the driven check pawl 34 are both disengaged from the ratchet body 31. At this time, the striking device 2 will move forward under the elastic force of the first spring 5 and strike the electric energy converter 1, so that the electric energy converter 1 converts the instantaneous mechanical impact into electric energy, and the instantaneous current generated by the electric energy converter 1 is used to trigger the ignition wire of the self-starting fire extinguishing device. When it is necessary to restore the standby state, the operating lever 33 needs to be rotated upward, and the reset assembly 35 is operated to drive the driven check pawl 34 to be reset. The active gravity pawl 32 can be automatically reset under the action of gravity. At the same time, the traction rope 4 is wound around the ratchet body 31 again, and the traction rope 4 drives the striking device 2 to compress the first spring 5 for energy storage.

[0065] Although the specific implementation manners of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present utility model should be covered by the scope protected by the claims of the present utility model.
