[0026] As Figure 1 shown, an emergency drainage device for fire-fighting equipment according to the present application comprises a water pump 1, a quick connection pipe 2, a support frame 3, and a pressure relief valve 4.

[0027] The water pump 1 provides the necessary power for the drainage device. It is equipped with a quick connector 11, which is an important component for quickly connecting the water pump 1 with other components. The interface of the quick connector 11 is designed as a self-locking plug-in interface 12, which is internally provided with a sealing spring ring 13 to ensure the sealing of the interface; while the outer contour is provided with anti-skid ribs 14 to ensure the stability and convenience of the operator's hands. In technical practice, the quick connector 11 can be made of high-strength materials, combined with high-precision machining technology to make the self-locking structure, and the sealing spring ring 13 made of wear-resistant material is inlaid at the interface to ensure the effective sealing under long-time operation; at the same time, the surface texture is specially treated to form anti-skid ribs 14, which can improve the friction coefficient without causing any adverse effects on other functions of the quick connector 11.

[0028] The quick connection pipe 2 is used for connecting the output end of the water pump 1 with the quick connector 11. Specifically, one end of the quick connection pipe 2 is fixed to the output end of the water pump 1, and the other end is connected to the quick connector 11 in a freely pluggable manner. From a technological point of view, the quick connection pipe 2 is made of a pipe material with good flexibility and high strength, such as high-quality rubber or a specific type of soft plastic, and the two end fixing points are connected by heat bonding or ultrasonic welding. In this way, the pipe can be easily plugged and unplugged, and can withstand a large pressure.

[0029] In order to keep the water pump 1 stable and reduce the shaking phenomenon during operation, the support frame 3 is fixedly connected to the bottom surface of the water pump 1. It should have sufficient strength and hardness to bear the weight of the entire system while preventing deformation from affecting work efficiency. Considering factors such as cost and production difficulty, the support frame 3 is made of steel or other alloy metals and is firmly installed under the water pump 1 by welding, which can meet the requirements.

[0030] The pressure relief valve 4 is used to balance the pressure difference before and after the water flow enters the drain pipe, ensuring the safety and stability of the operation. It is usually placed in the area between the water outlet side of the water pump 1 and the quick connection pipe 2, so as to more accurately and timely monitor and control the water flow and its accompanying changes. For example, a small-diameter stop valve with sensitive response performance can be made of stainless steel as the main material, and the internal elastic element can be adjusted to sense the external water flow fluctuation signal and release the pressure in time to achieve the purpose of safety protection.

[0031] The self-locking plug-in interface 12 and the built-in sealing spring ring 13 designed in the utility model greatly improve the convenience and reliability of the water pump 1 connection.

[0032] In one embodiment, further referring to Figure 2 , the quick connector 11 of the emergency drainage device for fire fighting equipment of the present application adopts a self-locking plug-in interface 12 and introduces a clasp spring structure 15. This design enables the device to achieve convenient and safe connection during fire fighting drainage, thereby improving the reliability and efficiency of use. In the specific implementation scheme, when the connection mechanism of the quick connector 11 is involved, considering the demand for emergency drainage in actual application and the convenience of operation for the operator, the clasp spring structure 15 is integrated into the design of the self-locking plug-in interface 12. Specifically, the self-locking plug-in interface 12 is internally configured with a clasp spring, which ensures the safety and reliability of the plug-in operation through reasonable mechanical design. In terms of installation position, the structure is located near the interface of the quick connector 11 and is in butt joint with the quick connection pipe 2, ensuring that the locking or releasing action can be automatically completed during the pipe connection or disconnection process without the need for additional manual fastening devices.

[0033] For example, when the quick connection pipe 2 is inserted into the quick connector 11, a radial locking force is provided by the snap spring preloaded in the plug-in interface, so that the interface is in close contact and does not loosen, and when it is necessary to disconnect, the locking state is released by applying appropriate operating force to the snap spring, and then the pulling-out action is smoothly completed. The whole process is based on the simple and efficient physical principle, avoiding the need for complex control structure, ensuring the simplicity and stability of the interface part. At the same time, in order to prevent accidental falling, the design of the snap spring also integrates the anti-falling function, which can ensure the firmness of the interface even under the influence of external vibration or pressure change.

[0034] In one embodiment, the self-locking plug-in interface 12 of the emergency drainage device for fire-fighting equipment of the present application is provided with a plurality of sealing rings 16 inside. This design ensures that efficient and tight sealing effect can be achieved when the interface is connected. Specifically, the plurality of sealing rings 16 are installed in the self-locking plug-in interface 12 to improve its waterproof and pressure resistance, effectively preventing water leakage. The self-locking plug-in interface 12 is a quick, reliable and easy-to-operate connector, especially suitable for drainage devices in emergency environments. Due to the factors such as high pressure or vibration in the working conditions, the internal multi-layer sealing design of the plug-in interface significantly enhances its durability and reliability. In addition, the presence of the sealing ring also helps to reduce the performance degradation rate after long-term use, ensuring stable connection and sealing effect after each plug-in and pull-out.

[0035] In one embodiment, the self-locking plug-in interface 12 is made of metal material to enhance the mechanical strength and durability, and a plurality of sealing rings of different materials and structures are arranged in the interface, which are nested in sequence to form a multi-layer sealing structure. For example, the innermost layer can be made of high-pressure resistant rubber material, the middle layer can be high-grade chemical inert material such as fluorosilicone to adapt to various complex working conditions, and the outer layer can be soft material with certain elasticity to optimize the operation experience of insertion and pull-out, while ensuring tight contact without gaps. Each sealing ring is firmly fixed in its designated position to provide stable and durable sealing protection.

[0036] In one embodiment, one of the key design features of the emergency drainage device for fire-fighting equipment of the present application is the anti-slip rib 14 on the outside of the quick connector 11. Specifically, the anti-slip rib 14 is in a spiral structure. This unique shape is designed to provide better grip and touch between the operator and the outer surface of the quick connector 11. In addition, this spiral anti-slip rib 14 has visual recognition, which helps to position the connection component more conveniently during field use, while also helping to reduce the risk of accidental slipping caused by wet hands or gloves.

[0037] The spiral anti-skid ribs 14 are evenly distributed and have a certain depth around the entire external contour of the interface. This structure not only enhances the feel and stability during operation, but also increases the surface friction coefficient, ensuring smooth and rapid plug-in and plug-out operations without slipping. From a material perspective, the spiral anti-skid ribs 14 are made of a material with good corrosion resistance, effectively meeting the special requirements of fire-fighting equipment for long-term use in humid and highly corrosive working environments.

[0038] For example, a numerical control machine tool precision cutting process can be used during the manufacturing of the quick connector 11 to directly process spiral lines on the surface of the shell. Alternatively, a one-time molding technology can be used to complete the manufacturing of the anti-skid ribs 14, ensuring the quality and specification consistency of each production piece. In this embodiment, the selected material needs to have high mechanical strength and good plasticity to ensure that the spiral lines formed after cutting or injection molding are clear and accurate, without affecting the overall performance of the quick connector 11.

[0039] Continuing to refer to Figure 2 In one embodiment, the quick connector 11 of the emergency drainage device for fire-fighting equipment of the present application is provided with a handle 17 on the outside, which facilitates manual operation for plug-in and plug-out, and releases the connection through a pressing method. This design is particularly suitable for use scenarios that require rapid disassembly and assembly, to adapt to the convenience of on-site operation and the requirements of emergency response. The handle 17 design allows the operator to more stably and easily complete the installation and disassembly of the quick connector 11. The specific position of the handle 17 is installed around the outside of the quick connector 11, ensuring that it is easy to access and does not interfere with the normal function of other components. The handle 17 is connected to the internal self-locking plug-in and plug-out interface 12 through a mechanical linkage, and when the handle 17 is operated, it can directly act on the plug-in and plug-out mechanism to achieve safe and rapid separation or firm connection of the quick connector 11.

[0040] For example, the quick connector 11 can adopt a double-layer structure, containing the self-locking plug-in and plug-out interface 12 and related mechanical interlocking mechanisms inside. The handle 17 on the outside of the quick connector 11 is connected through a hinge or a flexible pin shaft, and can transmit motion to the internal separation button according to the pressing force of the user, thereby triggering the release action of the lock. The design of this mechanism allows the user to only need to lightly press the handle 17 to unlock the quick connector 11, and after releasing the handle 17, the handle 17 is automatically reset to the locked state by the action of the internal spring, ensuring the safety of the connection. In addition, a sealing ring is located at the interface of the quick connector 11, which can ensure water tightness at the connection in the plugged-in state, avoiding leakage problems. The anti-skid ribs 14 are distributed around the outside of the quick connector 11 to increase the feel and control accuracy of the user during plug-in and plug-out operations.

[0041] In one embodiment, as Figure 3As shown, the water pump 1 of the emergency drainage device for fire-fighting equipment of the present application is provided with a fixing groove 18 for fixing the support frame 3, which ensures the stability of the entire device during operation. Through the fixing groove 18, the support frame 3 can be accurately and firmly inserted and locked therein. Specifically, the presence of the fixing groove 18 not only provides a stable support base for the support frame 3, but also ensures the consistency and coordination of the overall structure of the device, thereby improving the working reliability of the fire-fighting drainage device. In addition, the locking mechanism between the fixing groove 18 and the support frame 3 further enhances the stability of their combination.

[0042] For example, in order to enable the support frame 3 to be reliably inserted into the fixing groove 18 and locked therein, a guide slope and a limiting device can be provided inside the fixing groove 18 to guide the support frame 3 to smoothly enter the fixing groove 18 and be automatically locked at a specific position. The support frame 3 is correspondingly provided with a structural member matching the limiting device, which can trigger the locking component in the fixing groove 18 to fix it when the support frame 3 is inserted into place. This way not only is easy to operate and highly safe, but also ensures that the support frame 3 can still be accurately and correctly installed and removed after long-term use.

[0043] In one embodiment, with particular reference to Figure 2 The pressure relief valve 4 of the emergency drainage device for fire-fighting equipment of the present application is installed on the pipeline between the water pump 1 and the quick connection pipe 2. In order to ensure that the pressure relief valve 4 can be stably and reliably connected between the water pump 1 and the quick connection pipe 2, the device uses a flange 19 as a connection interface. The flange 19 is a common mechanical connection method that can achieve firm connection between two components and ensure the sealing of the fluid passage. In this embodiment, the flange 19 not only plays a fixing role, but also has the function of preventing leakage.

[0044] In addition, in order to prevent the pressure relief valve 4 from being accidentally opened or loosened, a safety locking screw 20 is specially added during assembly. This design ensures that the connection will not easily come off or loosen under any sudden circumstances, such as vibration or other external forces, thereby ensuring the stability and safety of the entire system. The safety locking screw 20 usually passes through the hole on the flange 19 in the form of threads and is fastened with the corresponding position.

[0045] For example, during installation, the axes of the water pump 1, the flange 19 and the quick connection pipe 2 need to be aligned. Then the flange 19 is sleeved into the outlet end of the water pump 1 and tightly connected with one end of the quick connection pipe 2. After installation, the safety locking screw 20 is tightened to firmly fix the pressure relief valve 4 between the two components, thereby completing the assembly of the entire connection structure. The emergency drainage device designed in this way is suitable for occasions that require quick installation and removal, and ensures stable operation under high pressure conditions.

[0046] In one embodiment, the anti-skid rib 14 of the emergency drainage device for fire-fighting equipment of the present application is externally marked with a size 21. This feature allows the operator to intuitively read the actual length of the pipe without the need for other measuring tools, improving the portability and ease of use of the device. The marking method uses materials and processes that are not easily erased and are clearly visible, ensuring that the size 21 information remains accurate and reliable even after long-term use and in complex working environments.

[0047] This structural design is particularly suitable for scenarios where water pipes need to be quickly laid and the remaining length of the pipe needs to be accurately determined on the fire scene. For example, when dealing with fires, firefighters can accurately determine the required pipe diameter according to the size 21 and adjust the plan accordingly, improving the flexibility and response speed of rescue work.

[0048] In one embodiment, the specific implementation of the emergency drainage device for fire-fighting equipment of the present application includes a buffer section 22 between the water pump 1 and the quick connector 11. The buffer section 22 is arranged between the output end of the water pump 1 and the quick connector 11. This design aims to optimize the connection and working performance of the system. The buffer section 22 has a certain flexibility and strength, which can alleviate the impact caused by pressure and vibration when connecting the water pump 1 and the quick connector 11.

[0049] The buffer section 22 is made of a specific material that has sufficient strength to withstand the forces and fluid pressures generated during operation; at the same time, it has appropriate flexibility to absorb the high-frequency vibrations and transient forces caused by pulsating water flow during the operation of the water pump 1, ensuring the overall stability of the system while reducing the fatigue damage that may be caused to the connection parts.

[0050] For example, a buffer sleeve made of a pre-shaped memory alloy or rubber material can be installed between the pump body outlet pipe and the quick connector 11 interface. One end of the buffer sleeve is fixed to the corresponding interface edge on the pump body, and the other end wraps around the connecting pipe part of the quick connector 11, and a clamp or other means is used to securely fasten and ensure the sealing. In this way, an intermediate buffer protection link is added while maintaining the normal transmission function of the water flow.

[0051] In one embodiment, as Figure 4As shown, the sealing spring ring 13 of the emergency drainage device for fire-fighting equipment of the present application is provided with guide grooves 23 on both sides. This structure further ensures the close fit and stable operation of the connecting components. In order to ensure sealing performance and prevent water leakage under high-pressure working conditions, the installation position of the sealing spring ring 13 is specially designed to ensure normal operation under various complex working conditions. This position is inside the quick connector 11 of the water pump 1. The quick connector 11 serves as an intermediate part, which is connected to the quick connection pipe 2 at one end while directly connected to the water pump 1, and bears multiple responsibilities of the interface part.

[0052] In terms of structural details, the guide grooves 23 are located on both sides of the sealing spring ring 13. The guide grooves 23 provide a precise assembly path and positioning function for the sealing spring ring 13, preventing displacement of the spring ring during assembly or use, which can cause poor sealing and other problems. At the same time, the sealing spring ring 13 can slide along the guide groove 23 under stress and maintain stable springback effect, thereby ensuring smooth operation of the self-locking plug-in interface 12. In actual operation scenarios, such as maintenance and replacement of the water pump 1 on site, technicians can easily align the interface insertion to ensure good sealing and reduce water leakage. The entire process relies on the precise guidance provided by the guide grooves 23 to avoid deviation and achieve reliable connection. The combination of the guide grooves 23 and the sealing spring ring 13 optimizes the overall assembly precision and work efficiency. In addition, this design can complete the disassembly and assembly tasks independently without additional auxiliary tools or accessories, greatly improving the emergency repair response capability.

[0053] For example, two parallel recessed strips can be constructed around the sealing spring ring 13 as part of the guide grooves 23. These guide grooves 23 extend from one side of the plane where the sealing spring ring 13 is located, and the opening faces the external environment to facilitate the assembly process. Before the quick connection pipe 2 is inserted, the guide grooves 23 can first contact the external pipe opening, and then guide the latter to nest correctly into the inner space and contact the sealing spring ring 13 through its shape. This method is not limited to the choice of materials, and any alloy metal or specially designed composite material with sufficient hardness and elasticity is suitable for this structure.

[0054] In actual operation, when the device is used, the quick connector 11 of the water pump 1 can be connected with other components of the emergency drainage system. Since the interface of the quick connector 11 adopts a self-locking plug design and is internally provided with a sealing spring ring 13, it is convenient to quickly connect or disconnect the device while ensuring sealing. The anti-slip ribs 14 provided on the outer profile of the interface improve the feel and safety of operation, avoiding slipping during operation. Then, one end of the quick connection pipe 2 is connected with the output end of the water pump 1, and the other end is tightly connected with the quick connector 11, ensuring smooth water flow without leakage. The support frame 3 provides stable basic support, so that the water pump 1 can be stably placed in any suitable operating position. After the water pump 1 is started, the accumulated water is pumped out and effectively discharged through the quick connection pipe 2. At the same time, the pressure relief valve 4 is installed between the water pump 1 and the quick connection pipe 2, which can be automatically opened when the pressure in the system is too high to protect the entire drainage device from overpressure damage, ensuring the safety and reliability of the entire drainage operation.

[0055] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
