Description

Technical Field

[0001] This application relates to the field of fire-fighting equipment and fluid control mechanical structure technology, specifically a novel valve structure for a fire-fighting water tank. Background Technology

[0002] Firefighting equipment and fluid control mechanical structures often manifest as various valve structures in daily life.

[0003] Among numerous fire-fighting equipment, the valve structure of fire water tanks is a key component controlling the release and shut-off of water sources, and its performance directly affects the response speed and reliability of the fire extinguishing system. Currently, the commonly used valve structures on the market include ball valves, gate valves, and butterfly valves. Although these valves are widely used in general industrial pipelines, common valves are mainly standardized designs, adapted to straight pipes or flange interfaces. However, fire water tanks are usually irregular in structure and space-constrained, making direct installation difficult. Additional customized adapter structures are required, increasing system complexity and installation costs. Especially in special scenarios such as fire water tanks, due to structural issues, it is difficult to integrate them into compact spaces or custom-shaped fire water tanks, which is particularly unfavorable for mobile or unattended fire-fighting devices.

[0004] Therefore, this application provides a novel valve structure for fire-fighting water tanks to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a novel valve structure for fire-fighting water tanks, aiming to solve the problem of poor space adaptability of existing valves in fire-fighting water tank applications due to their installation methods, as mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a novel valve structure for a fire bucket, comprising an outer shell, the outer shell including a parallel upper fixing plate and a lower fixing plate, and a honeycomb cylindrical wall fixedly installed at corresponding edge positions between the upper and lower fixing plates by screws. A valve hole is provided on the lower fixing plate, a cross platform is fixedly installed on the honeycomb cylindrical wall, a servo motor is fixedly installed at the center of the cross platform, and a drive frame is fixedly installed on the output shaft of the servo motor by screws. One end of the drive frame near the lower fixing plate is connected to a valve plate matching the valve hole via at least three sets of connecting posts arranged in a circular array. Thus, the outer shell, assembled from the upper fixing plate, lower fixing plate, and honeycomb cylindrical wall by screws, allows for flexible adjustment of the installation angle according to the shape of the fire bucket, adapting to irregular containers. Furthermore, the servo motor, drive frame, and valve plate are integrated within a limited space, eliminating the need for additional adapter structures and reducing installation complexity.

[0007] Preferably, the honeycomb cylinder wall is composed of four honeycomb blocks spliced ​​together, with adjacent honeycomb blocks connected by pins, and the four ends of the cross platform are all fitted into the center of the pins to fix them at the joint of adjacent honeycomb blocks.

[0008] Preferably, the connecting column includes a plurality of sleeve rods fixedly connected to the side of the drive frame near the valve plate and arranged in a circular array, a plurality of inner rods fixedly connected to the side of the valve plate near the drive frame and arranged in a circular array, and a spring disposed inside the sleeve rods and having its two ends abutting against the sleeve rods and the inner rods respectively, wherein the sleeve rods are fitted outside the inner rods.

[0009] Preferably, the drive frame has several flow guide ports.

[0010] Preferably, the cross platform is fixedly connected to an elastic cable whose other end is connected to the drive frame for resetting the drive frame, and at least two elastic cables are provided.

[0011] Preferably, each of the four support arms of the cross platform is fixedly connected with a silicone shock-absorbing pad that contacts the top surface of the drive frame.

[0012] Preferably, the servo motor adopts magnetic coupling sealing technology, and both the servo motor and the circuit part are protected by IP67 level, with key components coated with anti-rust coating.

[0013] The new valve structure of this fire water tank consists of an upper fixed plate, a lower fixed plate, and a honeycomb cylinder wall assembled with screws. The installation angle can be flexibly adjusted according to the shape of the fire water tank to adapt to irregular containers. Furthermore, the servo motor, drive frame, and valve plate are integrated in a limited space, eliminating the need for additional adapter structures and reducing installation complexity.

[0014] The novel valve structure of this fire bucket utilizes Hooke's Law to provide a pulling force opposite to the servo motor's driving force. When the servo motor loses power or becomes uncontrollable, the elastic cable drives the valve plate to be forcibly reset to the closed state, improving safety in emergency power outage situations and enhancing the reliability of the valve structure.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This embodiment provides a novel valve structure for fire-fighting water tanks, such as... Figures 1-3 As shown, the novel valve structure of the fire water tank includes an outer shell 1. The outer shell 1 includes an upper fixing plate 11 and a lower fixing plate 12 arranged in parallel, and a honeycomb cylindrical wall 13 fixedly installed at the corresponding edge position between the upper fixing plate 11 and the lower fixing plate 12 by screws. The lower fixing plate 12 has a valve hole 121. A cross platform 2 is fixedly installed on the honeycomb cylindrical wall 13. A servo motor 5 is fixedly installed at the center of the cross platform 2. A drive frame 3 is fixedly installed on the output shaft of the servo motor 5 by screws. The end of the drive frame 3 near the lower fixing plate 12 is connected to a valve plate 4 that matches the valve hole 121 through at least three sets of connecting posts 6 arranged in a ring array.

[0029] In use, the valve plate 4 remains closed under the self-locking function of the servo motor 5, tightly fitting the valve hole 121 to prevent water flow. When the servo motor 5 receives a control signal, its output shaft drives the drive frame 3 to rotate. The drive frame 3 drives the valve plate 4 to rotate through at least three sets of connecting columns 6 arranged in a ring array. The valve plate 4 and the valve hole 121 on the lower fixed plate 12 form a matching sealing structure. When the valve plate 4 rotates under the drive of the servo motor, the opening or closing control of the valve hole 121 can be realized.

[0030] Specifically, the honeycomb cylindrical wall 13 is composed of four honeycomb blocks 131. Adjacent honeycomb blocks 131 are connected by pins 132, and the four ends of the cross platform 2 are fitted into the center of the pins 132 to fix them at the joint of the two adjacent honeycomb blocks 131. The honeycomb cylindrical wall 13 is assembled by four honeycomb blocks 131 connected by pins 132, and the adjacent blocks form a mortise and tenon connection. The four ends of the cross platform 2 are fitted into the center of the pins 132, and the axial positioning of the pins 132 is used to fix it. This design utilizes the hexagonal geometric stability of the honeycomb structure to decompose the cylindrical wall into modular units, and at the same time, the pins 132 are used to achieve rapid assembly and positioning.

[0031] Furthermore, the connecting column 6 includes a plurality of sleeve rods 61 fixedly connected to the side of the drive frame 3 near the valve plate 4 and arranged in a circular array, a plurality of inner rods 62 fixedly connected to the side of the valve plate 4 near the drive frame 3 and arranged in a circular array, and a spring 63 disposed inside the sleeve rods 61 and abutting against the sleeve rods 61 and the inner rods 62 at both ends respectively. The sleeve rods 61 are fitted outside the inner rods 62. The springs 63 can provide preload to ensure that the sealing surface of the valve plate 4 and the valve hole 121 is evenly fitted, ensuring the stability of the valve opening and closing and maintaining control accuracy.

[0032] Understandably, the drive frame 3 has several flow guide ports. These ports can effectively reduce water flow resistance, keep the valve passage unobstructed, reduce structural stress, extend the service life of the drive frame 3, and reduce the drive torque requirement of the servo motor 5, thus reducing energy consumption.

[0033] Furthermore, the cross platform 2 is fixedly connected to an elastic cable 7, the other end of which is connected to the drive frame 3 for resetting the drive frame 3. There are at least two elastic cables 7. Hooke's law is used to provide a pulling force opposite to the driving force of the servo motor 5. When the servo motor 5 is de-energized or out of control, the elastic cable 7 drives the valve plate 4 to be forcibly reset to the closed state.

[0034] Furthermore, each of the four arms of the cross platform 2 is fixedly connected with a silicone damping pad 8 that contacts the top surface of the drive frame 3; the silicone damping pad 8 fills the contact surface between the arms of the cross platform 2 and the drive frame 3, and absorbs vibration energy through deformation, which can effectively protect the servo motor 5 and the drive frame 3 and extend their service life.

[0035] It should be noted that the servo motor 5 adopts magnetic coupling sealing technology, and both the servo motor 5 and the circuit part are IP67 level protected. Key components are coated with anti-rust coating. The output shaft of the servo motor 5 is connected to the external drive frame 3 by magnetic force transmission, without mechanical shaft seal, which completely eliminates liquid leakage. The circuit part is potted with epoxy resin and has an anti-rust coating, which can improve the service life of the device in water.

[0036] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
