Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to an aramid-reinforced fire-fighting rubber water bladder. Background Technology

[0002] Firefighting rubber water bladders, as portable, large-capacity water storage devices, are widely used in scenarios lacking fixed firefighting water sources, such as forest fire prevention and fire suppression in remote areas. To adapt to the complex and harsh environment at fire scenes, existing water bladders are usually reinforced with high-strength materials, such as using aramid fibers as a skeleton to improve the bladder's puncture and tear resistance, ensuring its structural robustness and durability.

[0003] In practical applications, to ensure that fire hydrants are always available, they are often deployed outdoors, using their openings to collect rainwater as a backup fire water source. However, this method inevitably allows debris such as leaves and sand to enter the hydrant along with the rainwater. If not filtered, this debris may clog the fire pump or nozzle during firefighting, delaying precious firefighting opportunities.

[0004] Although some existing water bladders have filters at the inlet, these filters are often integrally fixed to the water collector or the bladder itself. Over time, the filters become clogged with debris, severely impacting water collection efficiency. Due to the fixed structure, thoroughly cleaning or replacing the filters is extremely difficult and time-consuming, a significant drawback for firefighting equipment that requires constant readiness. Furthermore, if left unattended, once the water bladder fills with rainwater, excess water will overflow, wasting water and potentially making the surrounding ground slippery, compromising on-site safety.

[0005] Therefore, this utility model proposes an aramid-reinforced fire-fighting rubber water bladder to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the aramid-reinforced fire-fighting rubber water bladder, such as the difficulty in fixing, disassembling and maintaining the water collection and filtration device structure, the need for manual supervision after the water is full, and the easy occurrence of overflow, this utility model aims to provide an aramid-reinforced fire-fighting rubber water bladder with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an aramid-reinforced fire-fighting rubber water bladder, including a water bladder body and a water collector disposed on the water bladder body; a disassembly mechanism for detachably connecting the water collector to the water bladder body; and a blocking mechanism for automatically closing the water inlet passage when the water bladder body is full of water.

[0008] The disassembly mechanism includes a fixed block fixed to the water bladder body, and a threaded rod, a force-applying block, a force-receiving block, and a protruding block that cooperate with the fixed block. The threaded rod is threaded through the fixed block, and its end abuts against the force-applying block, which is slidably disposed within the fixed block. The force-receiving block is slidably connected to the fixed block and contacts the force-applying block, while the protruding block is fixedly connected to the force-receiving block.

[0009] Preferably, the blocking mechanism includes a fixed plate fixed to the water bladder body, an electric push plate mounted on the fixed plate, and a baffle plate movably connected to the fixed plate. The water collector is connected to the water bladder body via a transmission pipe. The baffle plate is driven by the output end of the electric push plate and can move laterally under the drive of the electric push plate, thereby blocking or opening the transmission pipe opening. This combination of disassembly and blocking mechanisms, through ingenious mechanical and electrical coordination, achieves convenient maintenance of the water collector and intelligent overflow prevention of the water bladder.

[0010] Preferably, the disassembly mechanism further includes a spring-loaded component disposed between the fixed block and the force-bearing block. The spring-loaded component applies an elastic restoring force to the force-bearing block, causing it to move in the direction of disengagement from the locking mechanism. This ensures that after the threaded rod is unscrewed to release the pressure, the force-bearing block can automatically and quickly retract, thereby causing the protruding block to disengage from the limit on the water collector.

[0011] In one specific implementation, the spring-loaded assembly includes a movable block fixed to the force-bearing block, and a spring with its two ends connected to the fixed block and the movable block respectively. Furthermore, the spring-loaded assembly also includes a damping rod, one end of which is fixed to the fixed block, and the other end passing through the movable block. This combination of spring and damping rod not only provides reliable reset power but also effectively absorbs impact, ensuring a smooth and stable disassembly operation.

[0012] Preferably, the blocking mechanism further includes a semi-circular plate fixed to the fixed plate, the semi-circular plate forming a guide rail for the blocking plate to slide. This structure provides the blocking plate with a stable and precise movement trajectory, ensuring that it will not deviate or jam during reciprocating motion, thus improving the reliability of the blocking action.

[0013] In another preferred embodiment, a sealing plate is fixedly connected to the side of the baffle plate facing the transmission pipe. The sealing plate is made of an elastic sealing material. When the baffle plate is moved into place, the elastic sealing plate can fit tightly against the opening of the transmission pipe, forming a reliable seal and effectively preventing water leakage.

[0014] Preferably, the filtration system inside the water collector has a structure in which a pre-filter and an activated carbon filter layer are arranged sequentially along the water flow direction. This staged filtration design allows the pre-filter to intercept large particles of impurities, protecting the subsequent activated carbon filter layer, extending its service life, and ensuring a dual purification effect on the water quality.

[0015] Preferably, a one-way valve is fixedly connected to the inlet of the water collector. The one-way valve only allows external water to flow in in one direction, which can effectively prevent the water stored in the tank from flowing out in reverse due to accidental squeezing or shaking, thus enhancing the safety of water storage.

[0016] Preferably, the bottom of the water bladder is integrally or fixedly connected to a leak-proof base, the bottom surface of which is flat for stable placement. The presence of the leak-proof base not only provides stable support for the entire water bladder but also forms double protection for the bottom of the bladder, further enhancing the durability and leak-proof capability of the device.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing water collection and filtration devices are usually integrated structures that are difficult to disassemble, clean, and maintain by setting up a disassembly mechanism consisting of a threaded rod, a force-applying block, a force-receiving block, and a spring-loaded component. It achieves the technical effect of quickly and conveniently separating the water collector for internal cleaning or filter replacement, greatly improving the maintainability of the equipment and extending its service life.

[0018] 2. This utility model solves the problem that existing fire water bladders rely on manual supervision after being full and cannot automatically close the inlet, which easily leads to overflow and waste of water resources. By setting up a blocking mechanism driven by an electric push plate to move the baffle plate and sealing plate, it solves the problem that existing fire water bladders rely on manual supervision after being full and cannot automatically close the inlet, which easily leads to overflow and waste of water resources. It achieves the technical effect of automatically and reliably sealing the inlet pipe when the water level reaches the preset value, realizes intelligent management of equipment, and improves the convenience and automation level of use.

[0019] 3. This utility model solves the problems of existing water bladders having single functions and structural designs that fail to fully consider both ease of operation and reliability by integrating the detachable water collection and filtration system with the automatic induction sealing system in a modular design. It achieves the technical effect of a compact and reasonable overall structure, high functional integration, and the dual advantages of easy maintenance and intelligent operation, significantly enhancing the overall practicality of the product.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Reference Figures 1 to 4 This utility model provides an aramid-reinforced fire-fighting rubber water bladder, which aims to solve the problems of difficult maintenance and disassembly of the water collection device of the fire-fighting water bladder in the prior art and easy overflow after the water is full.

[0024] The basic frame of the aramid-reinforced fire-fighting rubber water bladder includes a water bladder body 1. A leak-proof base 8 is integrally or fixedly connected to the bottom of the water bladder body 1. The bottom surface of the leak-proof base 8 is a flat structure for stable placement. A water collector 3 is provided on the upper part of the water bladder body 1. A one-way valve 2 is fixedly connected to the inlet of the water collector 3. A primary filter screen 4 and an activated carbon filter layer 7 are arranged sequentially along the water flow direction inside the water collector 3. The key structure of this utility model is that it also includes a disassembly mechanism 5 for detachably connecting the water collector 3 and the water bladder body 1, and a blocking mechanism 6 for automatically closing the water inlet passage when the water bladder body 1 is full of water. The overall structure of the disassembly mechanism 5 includes a fixing block 51 fixed to the water bladder body 1, and a threaded rod 52, a force-applying block 53, a force-receiving block 54, a spring-loaded assembly 55 and a protruding block 56 provided on the fixing block 51. These components work together to achieve the locking and releasing of the water collector 3. The overall structure of the blocking mechanism 6 includes a fixing plate 61 fixed to the water bladder 1, and an electric push plate 62, a baffle plate 63, a sealing plate 64 and a semi-circular plate 65 installed on the fixing plate 61; the transmission pipe 66 in the blocking mechanism 6 is used to connect the outlet of the water collector 3 and the inlet of the water bladder 1, thereby forming a complete water inlet passage.

[0025] The fixing block 51 of the disassembly mechanism 5 is fixed to the water bladder body 1, providing an installation reference for other moving parts; the threaded rod 52 is threaded through the fixing block 51, the force-applying block 53 is slidably disposed in the fixing block 51, the rod end of the threaded rod 52 abuts against the force-applying block 53, and the force-applying block 53 can be driven to produce axial displacement by rotating the threaded rod 52; the force-receiving block 54 is slidably connected to the fixing block 51 and contacts the force-applying block 53, and is used to transmit the thrust from the force-applying block 53; a protruding block 56 is fixedly connected to the force-receiving block 54, and the shape and size of the protruding block 56 are the same as those of the water collector 3. The upper limit structure is adapted to achieve snap-in or separation; the disassembly mechanism 5 also includes a spring-loaded component 55 disposed between the fixed block 51 and the force block 54. The spring-loaded component 55 includes a movable block 551 fixed to the force block 54, one end of the damping rod 552 fixed to the fixed block 51, and the other end passing through the movable block 551. The spring 553 is sleeved on the outer periphery of the damping rod 552 and abuts against the movable block 551. This structure provides the force block 54 with an elastic restoring force to move in the direction of disengagement from the snap-in, and uses the damping rod 552 to ensure its smooth movement. The fixing plate 61 of the blocking mechanism 6 is fixed to the water bladder 1, and the electric push plate 62 is installed on the fixing plate 61 as the power source of the entire mechanism. The baffle plate 63 is movably connected to the fixing plate 61 and is drivenly connected to the output end of the electric push plate 62. A semi-circular plate 65 is also fixed on the fixing plate 61. The semi-circular plate 65 forms a guide rail for the sliding of the baffle plate 63 to limit the movement trajectory of the baffle plate 63. A sealing plate 64 is fixedly connected to the side of the baffle plate 63 facing the transmission pipe 66. The sealing plate 64 is made of elastic sealing material. In the assembled state, the pipe opening of the transmission pipe 66 is directly opposite the movement path of the baffle plate 63. The electric push plate 62 drives the baffle plate 63 to move laterally along the guide rail of the semi-circular plate 65. Finally, the sealing plate 64 and the pipe opening of the transmission pipe 66 achieve sealing and separation, thereby accurately blocking or opening the water inlet passage.

[0026] In the rebound assembly 55, the two ends of the spring 553 are connected to the fixed block 51 and the moving block 551 respectively. When the force-applying block 53 does not apply pressure, the spring 553 is in a natural or pre-compressed state, providing a continuous restoring force for the force-bearing block 54. At the same time, the damping rod 552 slides in the hole of the moving block 551. Through viscous damping or friction damping effect, it effectively prevents the force-bearing block 54 from being rapidly impacted or vibrated under the action of the spring 553.

[0027] In the blocking mechanism 6, the sealing plate 64 is made of an elastic sealing material, such as silicone rubber or EPDM rubber, so that it can produce a certain elastic deformation when it comes into contact with the opening of the transmission pipe 66, thereby better filling any possible tiny gaps and achieving an airtight or liquid-tight sealing effect.

[0028] Inside the water collector 3, the primary filter 4 is located above the activated carbon filter layer 7. Water first passes through the primary filter 4 to intercept larger suspended solids such as leaves and sediment, protecting the downstream activated carbon filter layer 7 from rapid clogging. The activated carbon filter layer 7 adsorbs discoloration, odors, and dissolved organic matter in the water, achieving secondary purification of the collected water source. The one-way valve 2 is located at the front inlet of the water collector 3. Its structure can be a common flap valve, ball valve, or duckbill valve, ensuring that external water can smoothly enter the water collector 3. It also effectively prevents backflow and leakage of water inside the water bladder 1 when it is squeezed or moved. The leak-proof base 8 is integrally connected to the water bladder 1 through a hot vulcanization process, or fixed with high-strength adhesives and mechanical fasteners. The leak-proof base 8 is made of more wear-resistant and durable rubber or composite materials, increasing the strength and puncture resistance of the entire bottom of the water bladder.

[0029] The implementation principle of this application embodiment is as follows: The fire-fighting rubber water bladder consists of a water bladder body 1 and a leak-proof base 8. It automatically accumulates water under the action of a one-way valve 2 and a water collector 3. The rainwater is filtered by the primary filter screen 4 and the activated carbon filter layer 7 inside the water collector 3. It is disassembled under the action of a disassembly mechanism 5 and blocked under the action of a blocking mechanism 6.

[0030] First, when the operator needs to disassemble the water collector 3, the operator can use the disassembly mechanism 5 to disassemble it. The operator first unscrews the threaded rod 52 inside the fixing block 51, so that the internal force-applying block 53 has no power, so that the force-bearing block 54 is moved by the spring-loaded component 55. This causes the moving blocks 551 on both sides of the force-bearing block 54 to move downward under the action of the damping rod 552 and the spring 553. Because there is a protruding block 56 on the left side of the force-bearing block 54, the force-bearing block 54 drives the protruding block 56 to disengage from the internal limit of the water collector 3, thereby allowing the water collector 3 to be disassembled.

[0031] During the process of water accumulation in the fire-fighting rubber water bladder, when the sensor fixed to the bottom of the fixed plate 61 senses that the bladder is full of water, it causes the electric push plate 62 to move the baffle plate 63, thereby bringing the two baffle plates 63 closer together, causing the two sealing plates 64 to move against each other, and causing the baffle plate 63 to slide within the semi-circular plate 65, thereby blocking the transmission pipe 66.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
