Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a tipping mechanism for a fire extinguishing agent storage tank. Background Technology
[0002] In the field of fire safety, extinguishing agent storage tanks are key equipment for ensuring the effectiveness of fire fighting. Their performance and condition directly affect whether fire extinguishing operations can be carried out quickly and effectively when a fire occurs. Extinguishing agent storage tanks are typically used to store various extinguishing agents, such as dry powder, foam, or gaseous extinguishing agents. Before filling with extinguishing agents, the storage tank needs to be inverted for a certain period of time, generally 24 hours, to allow any moisture inside to drain out under gravity, ensuring the tank is dry and thus guaranteeing the quality and extinguishing performance of the extinguishing agent. Currently, the inversion of extinguishing agent storage tanks is usually done manually. However, these tanks typically have considerable weight and volume, especially large ones weighing hundreds of kilograms. Manual inversion requires multiple operators working together, using crowbars, hoisting equipment, and other auxiliary tools, resulting in slow efficiency and wasted manpower. Utility Model Content
[0003] The purpose of this invention is to provide a flipping mechanism for fire extinguishing agent storage tanks, which facilitates the flipping and inverting of the fire extinguishing agent storage tanks, improves the efficiency of flipping and inverting the storage tanks, saves manpower, and is simple to operate and has a stable structure.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A tipping mechanism for a fire extinguishing agent storage tank includes a support frame. Multiple base plates are evenly spaced at the lower end of the support frame. A lifting device is provided at the upper end of each base plate. A support shell is provided inside each lifting device. A first rotating shaft is rotatably connected inside each support shell. A gear is provided on the outer side of each first rotating shaft. A second rotating shaft is rotatably connected inside each support shell near the corresponding first rotating shaft. A synchronous transmission mechanism is provided between each first rotating shaft and the corresponding second rotating shaft.
[0006] Each gear has a semi-circular first limiting plate at one end. Each second shaft has a semi-circular second limiting plate on its outer side, near the corresponding first limiting plate and opposite to it. Each support housing has a vertical limiting shaft on its lower end away from the corresponding second shaft. Each limiting shaft has a rack that meshes with the corresponding gear slidably connected to its outer side. Each rack has a magnetic block on its outer end away from the corresponding gear. Each support housing has an electromagnet that cooperates with the corresponding magnetic block on its upper inner end. Each limiting shaft has a spring that is initially compressed between the corresponding rack and the corresponding support housing. Each first shaft has a fixing device on both its left and right ends. Each fixing device has a detachable storage tank inside it.
[0007] By adopting the above technical solution, during use, when the electromagnet is energized, an interaction force is generated between the electromagnet and the magnetic block, causing the rack to slide relative to the limiting rod, compressing the spring. The rack rotates, simultaneously driving the gear to rotate. The gear drives the first rotating shaft and the first limiting plate to rotate. The first rotating shaft drives the fixing device to rotate. Through a synchronous transmission mechanism, the first rotation drives the second rotating shaft to rotate synchronously. The second rotating shaft drives the second limiting plate to rotate. When the gear drives one end of the first limiting plate to abut against the second limiting plate, the gear stops rotating, and the fixing device stops rotating. Then, the storage tank is placed on the bottom plate and fixed by the fixing device. Then, the electromagnet is stopped, and the rack resets under the action of the spring, thereby driving the gear to rotate and reset. The gear drives the other end of the first limiting plate to abut against the second limiting plate, thereby causing the storage tank to rotate 180 degrees, completing the inversion of the storage tank. The height of the fixing device can be adjusted by the lifting device to facilitate fixing the storage tank. At the same time, the height of the inverted storage tank can be adjusted to facilitate the outflow of water from the storage tank.
[0008] A further feature of this invention is that the lifting device includes multiple optical axis supports evenly spaced at the upper end of each base plate, a fixed joint provided at the upper end of the bracket near each optical axis support, a detachable sliding shaft vertically arranged between each optical axis support and the corresponding fixed joint, a box-type slider slidably connected to the outer side of each sliding shaft and connected to the corresponding support shell, and a lifting cylinder vertically arranged at the upper end of each base plate for moving the corresponding support shell.
[0009] A further feature of this invention is that the synchronous transmission mechanism includes a first pulley disposed at one end of the outer side of each first rotating shaft, a second pulley disposed on the outer side of each second rotating shaft near the corresponding first pulley, and a transmission belt disposed between each first pulley and the corresponding second pulley for transmission.
[0010] A further feature of this invention is that the fixing device includes bearing supports rotatably connected to the corresponding support shell at both ends of each rotating shaft, a support plate at the end of each bearing support away from the corresponding rotating shaft, clamping arms at the upper and lower sides of the end of each support plate away from the corresponding support shell, a fixing ring at the end of each clamping arm away from the corresponding support plate, a threaded opening at one end of each fixing ring, and a fixing bolt rotatably connected to the corresponding threaded opening at the other end of each fixing ring.
[0011] A further feature of this invention is that a controller is provided at one end of the bracket, and a power cord for connecting to a power source to provide power is provided at one end of the controller.
[0012] In summary, this utility model has the following beneficial effects:
[0013] Firstly, it facilitates the clamping and fixing of storage tanks. By connecting the fixing bolts on the fixing ring to the threaded joint, the size of the fixing ring can be adjusted, thus making it easy to stably fix storage tanks of different sizes.
[0014] Secondly, the lifting cylinder and box-type slider can easily move the fixed ring, adjust its height, and determine the movement distance. By adjusting the height of the fixed ring, it is easy to clamp and fix the storage tank stably, and also to adjust the height of the storage tank after inversion, so that the water in the storage tank can flow out easily.
[0015] Thirdly, it facilitates the inversion of the storage tank. Through electromagnets, magnetic blocks, and springs, it can easily drive the rack to move, thereby driving the first rotating shaft to rotate. This facilitates the rapid control and inversion of the storage block. Since the first and second limiting plates are both semi-circular and opposite to each other, the rotation angle of the first rotating shaft can be limited to 180 degrees, thereby controlling the stable inversion of the storage tank.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.
[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] Example, refer to Figure 1-5A tilting mechanism for a fire extinguishing agent storage tank includes a support 1. Three base plates 2 are evenly spaced at the lower end of the support 1. Each base plate 2 has a lifting device at its upper end. The support 1 has a fixed joint 4 near each fixed joint 3 at its upper end. A sliding shaft 5 is detachably connected between each sliding shaft 3 and the corresponding fixed joint 4. A support shell 7 is slidably connected between two sliding shafts 5 at the upper end of the same base plate 2. Each support shell 7 has a box-type slider 8 at its front and rear ends that is slidably connected to the corresponding sliding shaft 5, which facilitates the adjustment of the height of the support shell 7.
[0027] A horizontally arranged first rotating shaft 9 is rotatably connected between the middle of the left and right ends inside each support shell 7. A gear 10 is provided on the outer side of each first rotating shaft 9. A semi-circular first limiting plate 11 is provided on the left side of each gear 10. A horizontally arranged second rotating shaft 12 is rotatably connected to the rear of the corresponding first rotating shaft 9 inside each support shell 7. A semi-circular second limiting plate 13 is provided on the left end of the outer side of each second rotating shaft 12 and is opposite to the corresponding first limiting plate 11, which can facilitate limiting the rotation angle of the first rotating shaft 9 to 180 degrees.
[0028] A synchronous transmission mechanism is provided between each first rotating shaft 9 and its corresponding second rotating shaft 12. This mechanism includes a first pulley 19 located at the right end of the outer side of each first rotating shaft 9 and a second pulley 20 located at the right end of the outer side of each second rotating shaft 12. A transmission belt 21 is provided between each first pulley 19 and its corresponding second pulley 20 to enable the first rotating shaft 9 and the second rotating shaft 12 to rotate synchronously, thereby driving the first limiting plate 11 and the second limiting plate 13 to rotate synchronously.
[0029] A limiting shaft 14 is vertically arranged between the front sides of the upper and lower ends inside each support shell 7. A rack 15 that meshes with the corresponding gear 10 is slidably connected to the outer side of each limiting shaft 14. A magnetic block 16 is provided at the front end of each rack 15. An electromagnet 17 that cooperates with the corresponding magnetic block 16 is provided on the front side of the upper end inside each support shell 7. A spring 18 that is initially compressed is provided on the outer side of each first limiting shaft 14 between the lower end of the corresponding rack 15 and the corresponding support shell 7. This allows the first rotating shaft 9 to rotate easily, and the spring 18 can provide initial elastic force to prevent the first rotating shaft 9 from rotating arbitrarily. A controller 29 is provided on the right end of the bracket 1. A power cord 30 for connecting to a power source to provide power is provided at the lower end of the controller 29.
[0030] Each first rotating shaft 9 has a fixing device at both its left and right ends, including a bearing support 22 at each of its left and right ends that is rotatably connected to the corresponding support shell 7. Each bearing support 22 has a support plate 23 at the end away from the corresponding first rotating shaft 9. Each support plate 23 has clamping arms 24 on its upper and lower sides at the end away from the corresponding support shell 7. Each clamping arm has a fixing ring 25 at the end away from the corresponding support plate 23. Each fixing ring 25 has a threaded opening 26 at one end. Each fixing ring 25 has a fixing bolt 27 rotatably connected to the other end of the fixing ring 25 and threadedly connected to the corresponding threaded opening 26. Each fixing ring 25 has a storage tank 28 that can be detachably installed inside, which facilitates the installation and removal of the storage tank 28.
[0031] Usage: In use, power is supplied via a power cord. The controller 29 controls the energization of the electromagnet 17, generating an interaction force between the electromagnet 17 and the magnetic block 16. This force causes the rack 15 to slide relative to the limiting rod, compressing the spring 18. The rotation of the rack 15 simultaneously drives the gear 10 to rotate. The gear 10 then drives the first rotating shaft 9 and the first limiting plate 11 to rotate. The first rotating shaft 9 drives the bearing support 22 to rotate, which in turn drives the support plate 23. The support plate 23 then drives the clamping arm 24 and the fixing ring 25 to rotate. The first rotating shaft 9 simultaneously drives the first pulley 19 to rotate. The first pulley 19 drives the second pulley 20 to rotate via the transmission belt 21. The second pulley 20 drives the second rotating shaft 12 and the second limiting plate 13 to rotate as well. When the gear 10 drives one end of the first limiting plate 11 to abut against the second limiting plate 13, the gear 10 stops rotating. Then, the storage tank 28 is placed on the bottom plate 2 and fixed by the upper side of the clamping arm 24. The storage tank 28 is clamped and fixed by connecting the fixing bolt 27 on the fixing ring 25 to the threaded port 26.
[0032] Then, the power supply to the electromagnet 17 is stopped, and the rack 15 is reset under the action of the spring 18, thereby driving the gear 10 to rotate and reset. The gear 10 drives the other end of the first limiting plate 11 to abut against the second limiting plate 13, thereby driving the storage tank 28 to rotate 180 degrees. Since the spring 18 is initially compressed, the storage tank 28 will not rotate due to its own weight or other factors after being inverted, which helps to ensure the stability of the storage tank 28 after being inverted. The lifting cylinder 6 can drive the support shell 7 to move, and the support shell 7 drives the box-type slider 8 to slide relative to the sliding shaft 5, which facilitates the adjustment of the height of the fixing device and makes it easy to fix the storage tank 28. At the same time, it can also drive the inverted storage tank 28 to adjust its height, which facilitates the outflow of water from the storage tank 28.
[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. 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.
