Description

Technical Field

[0001] This invention belongs to the technical field of fire-fighting water supply booster equipment, specifically relating to a fire-fighting water supply booster device for high-rise buildings. Background Technology

[0002] In recent years, with the continuous increase in the number of high-rise buildings in cities, the requirements for pressure boosting, pressure stabilization, and continuous water supply reliability of building fire protection water supply systems have gradually increased. Existing high-rise building fire protection water supply boosting devices typically consist of pressure boosting and stabilizing equipment, outlet pipelines, check valves, and related control components. The pressure boosting and stabilizing equipment pressurizes the fire protection pipe network and uses check valves to prevent backflow of water in the pipe network, thereby ensuring that the fire protection system has a relatively stable water pressure when in standby or in operation.

[0003] Currently, due to the long length and numerous connections of fire protection pipelines in high-rise buildings, rust particles, scale, silt, or construction residues easily accumulate inside the pipes after long-term use. These impurities can easily get stuck between the valve core and valve seat after entering the check valve with the water flow, causing the check valve to open improperly, close incompletely, or return to its original position late. This can lead to fluctuations in the booster water supply pressure, affecting the stability and timeliness of the fire water supply. Existing solutions often require shutting down the machine and disassembling the check valve for cleaning, which is cumbersome, inefficient, and difficult to resolve in a timely manner in emergency fire water supply scenarios. Summary of the Invention

[0009] As a preferred embodiment of the high-rise building fire water supply booster device of the present invention, a first compression spring for resetting is elastically connected between the end of the telescopic button and the bottom surface of the inner cavity of the fixed housing.

[0010] As a preferred embodiment of the high-rise building fire water supply booster device of the present invention, the power storage component includes a fixed frame fixedly installed at the lower end of the anti-blocking sleeve cavity. The fixed frame has an upward-facing T-shaped groove in the middle. Trapezoidal telescopic blocks are slidably installed in the grooves on both sides of the lower end of the T-shaped groove. A second compression spring is elastically installed between the opposite side surface of the two trapezoidal telescopic blocks and the inner wall of the groove on both sides of the lower end of the T-shaped groove for limiting and resetting.

[0011] As a preferred embodiment of the high-rise building fire water supply booster device of the present invention, a lower base plate is snapped between the two trapezoidal telescopic blocks. The lower base plate is slidably disposed in the middle of the T-shaped groove. A central shaft is fixedly disposed in the middle of the lower base plate. The central shaft movably passes through the middle of the top rod and extends into the upper opening groove. A push head is fixedly disposed at the top of the top rod.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-8This is the first embodiment of the present invention, which provides a high-rise building fire water supply booster device. It achieves the effect of assisting in opening, loosening, and cleaning the valve core of the one-way valve 11 after it is jammed by debris during the fire water supply booster process. The device includes a pressure boosting and stabilizing unit 10, with a one-way valve 11 installed at one end of the outlet pipe. The device is characterized by: an anti-clogging sleeve 12 installed at the lower end of the one-way valve 11; a push rod 13 installed in the middle of the inner cavity of the anti-clogging sleeve 12; a rotary lifting assembly 14 installed at the lower end of the push rod 13; and a power assembly installed on one side of the rotary lifting assembly 14. 15. The rotating lifting assembly 14 and the power assembly 15 cooperate to open the closed one-way valve 11 valve core. The top of the push rod 13 is provided with an upper opening groove 20. The inner cavity of the upper opening groove 20 is provided with a T-shaped head 21. The lower end of the T-shaped head 21 is provided with a power storage assembly 22. The power storage assembly 22 is used to strike the T-shaped head 21 to make the valve core of the one-way valve 11 vibrate and loosen the stuck debris. The upper end of the push rod 13 is provided with a rotatable stabilizing bracket 30. The stabilizing bracket 30 is provided with a telescopic assembly 31. The telescopic assembly 31 rotates circumferentially along the inner ring surface of the one-way valve 11 and clears the debris stuck in the valve core.

[0026] The pressure boosting device 10 is used to stabilize or boost the pressure of the fire protection pipe network in high-rise buildings. The one-way valve 11 is installed on the outlet pipe of the pressure boosting device 10 to prevent backflow of water in the fire protection pipe network. Because the fire protection water supply pipes in high-rise buildings are long and have many fittings, rust particles, mud, scale or construction residue may exist in the pipes after long-term use. When the debris enters the one-way valve 11 with the water flow, it is easy to get stuck between the valve core and the valve seat of the one-way valve 11, resulting in the valve core not closing tightly, not opening smoothly or not returning to its original position in time. By setting an anti-blocking sleeve 12 at the lower end of the one-way valve 11, the installation and operation space of the top rod 13, the rotating lifting assembly 14, the power assembly 15, the energy storage assembly 22 and the telescopic assembly 31 can be provided without completely disassembling the one-way valve 11, thereby facilitating the auxiliary unblocking of the valve core of the one-way valve 11.

[0027] The rotary lifting assembly 14 includes a rotary cross 141 threaded through the middle of the top rod 13. The rotary cross 141 is located in the middle of the inner cavity of the anti-blocking sleeve 12. A gear ring 142 is fixedly installed on the outside of the rotary cross 141. The gear ring 142 is rotatably connected to the middle of the anti-blocking sleeve 12, and the middle of the inner cavity of the anti-blocking sleeve 12 has space for the gear ring 142 to rotate. A fixed cross 143 is provided at the lower end of the rotary cross 141. The fixed cross 143 is fixedly connected to the lower inner wall of the anti-blocking sleeve 12. The fixed cross 143 is movably connected to the threaded end of the top rod 13. Limiting grooves 144 are opened on both sides of the threaded end of the top rod 13. Limiting blocks 145 are slidably installed in the inner cavity of the two limiting grooves 144. The two limiting blocks 145 are fixedly connected to the fixed cross 143.

[0028] Furthermore, the rotating cross 141 and the push rod 13 are connected by a threaded connection. When the rotating cross 141 rotates, because the limiting block 145 on the fixed cross 143 extends into the limiting groove 144 on both sides of the push rod 13, the push rod 13 cannot rotate synchronously with the rotating cross 141, but can only move up and down along its own axis. Thus, the rotational motion of the rotating cross 141 can be converted into the linear lifting motion of the push rod 13, allowing the upper end of the push rod 13 to move towards the valve core of the one-way valve 11 and push the valve core. The cooperation between the limiting groove 144 and the limiting block 145 can, on the one hand, prevent the push rod 13 from deflecting during the lifting process, and on the other hand, improve the guiding stability of the push rod 13 when pushing the valve core, avoiding interference between the push rod 13 and the inner wall of the anti-blocking sleeve 12 after it deviates.

[0029] The power assembly 15 includes a fixed housing 151 fixedly disposed in the middle of one side of the anti-blocking sleeve 12. A fixed block 152 is fixedly disposed in the middle of the inner cavity of the fixed housing 151. A telescopic button 153 is movably disposed through the middle of the fixed block 152. The fixed block 152 and the telescopic button 153 are located on one side of the anti-blocking sleeve 12 and are set as a plane. A rack 154 is fixedly disposed on the plane of the fixed block 152 and the telescopic button 153. The rack 154 and the gear ring 142 mesh with each other for transmission. A first compression spring 155 for resetting is elastically connected between the end of the telescopic button 153 and the bottom surface of the inner cavity of the fixed housing 151.

[0030] Specifically, when it is necessary to assist in unblocking the valve core inside the one-way valve 11, the operator presses the telescopic button 153. The telescopic button 153 slides linearly along the fixed block 152, driving the rack 154 to move synchronously. Since the rack 154 meshes with the gear ring 142, the linear movement of the rack 154 can drive the gear ring 142 to rotate, and the gear ring 142 further drives the rotating cross 141 to rotate. When the rotating cross 141 rotates, through the threaded engagement between it and the push rod 13, the push rod 13 moves upward under the guidance and restriction of the limiting groove 144 and the limiting block 145, thereby using the T-shaped head 21 at the upper end of the push rod 13 to push the valve core of the one-way valve 11, so that the valve core that is stuck by debris or blocked by scale will have an opening gap.

[0031] When the operator releases the telescopic button 153, the first compression spring 155 pushes the telescopic button 153 back to its original position. The rack 154 moves in the opposite direction with the telescopic button 153, and drives the gear ring 142 and the rotating cross 141 to rotate in the opposite direction, causing the push rod 13 to return to its downward position. By repeatedly pressing and releasing the telescopic button 153, the push rod 13 can repeatedly push the valve core of the one-way valve 11, thereby facilitating the movement and clearing of slightly stuck valve cores and reducing the number of times the one-way valve 11 needs to be directly disassembled for maintenance.

[0032] Furthermore, the power storage component 22 includes a fixed frame 221 fixedly installed at the lower end of the inner cavity of the anti-blocking sleeve 12. The fixed frame 221 has an upward-facing T-shaped groove 222 in the middle. Trapezoidal telescopic blocks 223 are slidably installed in the grooves on both sides of the lower end of the T-shaped groove 222. A second compression spring 224 is elastically installed between the opposite side surface of the two trapezoidal telescopic blocks 223 and the inner wall of the grooves on both sides of the lower end of the T-shaped groove 222 for limiting and resetting.

[0033] A lower base plate 225 is snapped between two trapezoidal telescopic blocks 223. The lower base plate 225 is slidably disposed in the middle of the inner cavity of the T-shaped groove 222. A central shaft rod 226 is fixedly disposed in the middle of the lower base plate 225. The central shaft rod 226 movably passes through the middle of the top rod 13 and extends into the upper opening groove 20. A push head 227 is fixedly disposed at the top of the top rod 13. The upper end of the push head 227 abuts against the T-shaped head 21.

[0034] A tension spring 228 is sleeved on the outside of the push head 227. The upper diameter of the tension spring 228 is larger than the lower diameter. The upper diameter is larger than the diameter of the push head 227 but smaller than the lower diameter of the T-shaped head 21. The upper end of the tension spring 228 is fixed to the lower end of the T-shaped head 21. The lower diameter of the tension spring 228 is smaller than the diameter of the push head 227 and is used to pull the push head 227 upward.

[0035] The energy storage component 22 is mainly used to provide impact vibration force to the T-head 21 based on the push rod 13 pushing the valve core of the one-way valve 11. When the push rod 13 drives the T-head 21 to move upward and abut against the valve core of the one-way valve 11, relative displacement occurs between the central shaft 226, the push head 227, the tension spring 228 and the T-head 21. The tension spring 228 is stretched and forms elastic energy storage. The lower base plate 225 contacts the trapezoidal telescopic blocks 223 on both sides in the T-groove 222 and generates force through the two trapezoidal telescopic blocks 223. The compression causes the tension spring 228 to be stretched to a certain distance before the upward pulling force of the lower base plate 225 is greater than the pushing force of the springs on both sides of the trapezoidal telescopic block 223. This allows the lower base plate 225 to overcome the compression of the two trapezoidal telescopic blocks 223 and move upward rapidly under the pull of the tension spring 228. Consequently, the tension spring 228 drives the push head 227 to move upward rapidly. The push head 227 impacts or pushes the T-shaped head 21, causing the T-shaped head 21 to create an instantaneous impact on the valve core of the one-way valve 11, thereby loosening the scale, rust particles, or sand particles trapped between the valve core and the valve seat.

[0036] Preferably, the telescopic assembly 31 includes four retractable sleeves 311 fixedly mounted on the rotating cross 141. Each of the four retractable sleeves 311 has a retractable groove 312 inside. Each of the four retractable grooves 312 has a telescopic rod 313 slidably mounted inside. The telescopic rod 313 is fixedly connected to the stabilizing bracket 30 through the middle.

[0037] Each of the four telescopic rods 313 has a fixed inclined block 314 at its upper end. All four inclined blocks 314 are inclined outward and their upper ends abut against the inner wall of the anti-blocking sleeve 12. A cleaning block 315 is fixedly installed on the surface of the highest point of the inclined block 314. The cleaning block 315 is perpendicular to the surface of the telescopic rod 313.

[0038] It should be noted that the telescopic component 31 generates circumferential movement as the rotating cross 141 rotates. The stabilizing bracket 30 is used to synchronously support multiple telescopic rods 313, so that the multiple telescopic rods 313 maintain a relatively stable positional relationship when they move circumferentially around the top rod 13. Since the telescopic rods 313 can slide in the retraction groove 312 inside the retraction sleeve 311, when the inclined block 314 contacts the anti-blocking sleeve 12 or the lower inner wall of the one-way valve 11, the inclined block 314 can adaptively retract or extend according to the position of the contact surface, so that the cleaning block 315 is as close as possible to the inner ring surface around the valve core of the one-way valve 11. During the circumferential rotation, the cleaning block 315 can scrape the debris attached to the valve core or near the valve seat, so that the loosened particles can further get out of the stuck position.

[0039] When the pressure boosting and stabilizing device 10 is working normally, fire water flows through the one-way valve 11 into the fire water supply network of the high-rise building. The one-way valve 11 automatically opens or closes according to the water pressure. If the pipeline pressure is found to be unstable, the one-way valve 11 is not opening or closing smoothly, the valve core is suspected to be stuck by debris, or maintenance and dredging are required, the operator can press the telescopic button 153 on the side of the anti-blocking sleeve 12. The telescopic button 153 drives the rack 154 to move, the rack 154 drives the gear ring 142 to rotate, and the gear ring 142 drives the rotating cross 141 to rotate. The rotating cross 141 drives the push rod 13 to move upward through the threaded transmission, so that the T-shaped head 21 gradually approaches and pushes the valve core of the one-way valve 11, so that a loose space is formed between the valve core and the valve seat.

[0040] During the upward movement of the push rod 13, the energy storage component 22 works synchronously, the tension spring 228 stores energy, and the trapezoidal telescopic block 223 cooperates with the lower base plate 225 to achieve limiting and release. After release, the push head 227 impacts the T-shaped head 21 upward, causing the T-shaped head 21 to vibrate the valve core, thereby loosening the debris stuck in the valve core. At the same time, the rotating cross 141 drives the retracting sleeve 311 and the telescopic component 31 to rotate, and the inclined block 314 at the upper end of the telescopic rod 313 adjusts its extension and retraction according to the position of the inner wall. The cleaning block 315 scrapes circumferentially along the inner ring surface of the one-way valve 11 or the periphery of the valve core, further peeling off the loosened debris. After being loosened, the debris can be flushed out of the valve core jamming area by the water flow, or it can be cleaned up during subsequent maintenance and drainage.

[0041] After one unblocking operation is completed, the operator releases the telescopic button 153. The first compression spring 155 pushes the telescopic button 153 back to its original position. The rack 154 drives the gear ring 142 and the rotating cross 141 to rotate in the opposite direction. The push rod 13 returns to its original position downward under the action of threaded transmission and limit guide. The T-shaped head 21 disengages from the valve core of the one-way valve 11 to avoid affecting the normal use of the one-way valve 11. If the valve core is severely stuck, the push, vibration, and circumferential cleaning actions can be repeated by pressing the telescopic button 153 multiple times until the valve core of the one-way valve 11 returns to normal opening and closing.

[0042] Through the above-described process, this invention can assist in clearing debris stuck in the valve core of the one-way valve 11 without disassembling the entire valve or reducing the number of disassembly operations. Specifically, the rotary lifting assembly 14 and the power assembly 15 achieve stable lifting and pushing of the push rod 13, the energy storage assembly 22 provides elastic impact to loosen the valve core, and the telescopic assembly 31 provides circumferential adaptive cleaning of the inner ring surface surrounding the valve core. These three components work together to improve the reliability and maintenance efficiency of clearing the stuck one-way valve 11, and reduce the risk of the fire-fighting water supply booster device in high-rise buildings being affected by blockage or abnormal opening and closing of the one-way valve 11.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
