[0002] An emergency water injection system for storage tanks is used to reduce temperature, suppress fire, or mitigate the risk of fire spread by injecting water in the event of a fire or other emergency. Its main purpose is to quickly and effectively inject water into or around the storage tank to prevent or reduce damage from fire, ensuring the safety of equipment and personnel. It features cooling, fire extinguishing, leak prevention, and loss reduction. Emergency water injection systems play a crucial role in fire prevention and post-disaster emergency response, and are important facilities for ensuring production safety and protecting the lives and property of personnel. Current water injection system maintenance facilities are not perfect, for example, lacking operational monitoring of pipelines and maintenance of water injection nozzles. Therefore, this invention proposes an emergency water injection system for storage tanks that provides safety assurance for water injection operations, offers rich functionality, and allows for monitoring and maintenance of nozzles and pipelines. Summary of the Invention

A filling pump is also arranged in an array on the mounting bracket, and the outlet of each pump is connected to the filling valve at the bottom of the tank via a connecting transmission pipe to form a water injection path. A turntable is connected to one end of the connecting transmission pipe, and a mounting plate is connected to and raised on the filling pump, with the turntable and mounting plate rotatably connected and communicating. A reinforcement mechanism is provided at the other end of the connecting transmission pipe, comprising a nozzle connected to the connecting transmission pipe and a... The system includes a mounting base on the connecting transmission pipe, with a rotating array of reinforcing and clamping seats, each with a contact part. A connecting and reinforcing cylinder is mounted on the filling valve, which mates with the nozzle. A clamping telescopic shaft is arrayed around the circumference of the connecting and reinforcing cylinder, contacting and pressing against the contact part for reinforcement. A monitoring moving belt with a monitor attached is positioned on the outside of the connecting transmission pipe, moving along the outside of the pipe for operational monitoring. A maintenance and cleaning mechanism is mounted on the mounting bracket for cleaning and maintaining the nozzle.

[0005] Furthermore, the maintenance and cleaning mechanism includes a maintenance mounting frame mounted on a mounting bracket, a belt motor and a maintenance moving belt mounted on the maintenance mounting frame, the maintenance moving belt being driven by the belt motor; a moving seat is attached to the maintenance moving belt, a maintenance motor is mounted on the moving seat, and a washing part is mounted on the output shaft of the maintenance motor, the washing part being used to wash and maintain the nozzle.

[0006] Furthermore, a pressure cylinder is provided on the movable seat, and an impact plate is telescopically mounted on the telescopic rod of the pressure cylinder. A pressure-sensitive element for outputting feedback pressure change signals is connected between the impact plate and the telescopic rod of the pressure cylinder. The nozzle sprays water towards the impact plate to observe and verify the uniformity and pressure of the water spray.

[0007] Furthermore, the water inlet of the filling pump is provided with a filling connecting pipe and an antifreeze filler, the antifreeze filler being connected to the filling connecting pipe for transmitting and replenishing antifreeze.

[0008] Furthermore, the outlet end of the injection pump is equipped with a control electric cylinder, the telescopic rod of which is connected to the mounting plate to control the movement of the mounting plate; the mounting plate and the outlet end of the injection pump are connected by a connecting hose, and a rack and pinion electric cylinder is provided between each mounting plate, the telescopic rod of which is equipped with a rack and pinion, which meshes with the turntable.

[0009] Furthermore, a monitoring mounting bracket is provided on the outside of the docking transmission pipe. One end of the monitoring mounting bracket is fixedly connected to the turntable. A monitoring control motor is provided on the monitoring mounting bracket to drive the monitoring moving belt. The monitor is used to monitor cracks and leaks on the surface of the docking transmission pipe.

[0010] Furthermore, the reinforcement mechanism includes a control gear ring rotatably mounted on the mounting base, and a control mechanism is provided on the outside of the docking reinforcement cylinder for driving and controlling the reinforcement mechanism; a connecting shaft is connected to the reinforcement clamping seat, the connecting shaft is rotatably mounted on the mounting base, and a gear is provided at the end of the connecting shaft, the gear meshing with the control gear ring, and a torsion spring is sleeved on the connecting shaft, with both ends of the torsion spring connected to the mounting base and the reinforcement clamping seat respectively.

[0011] Furthermore, the control mechanism includes a support plate connected to the docking reinforcement cylinder. A motor and a lead screw are provided on the support plate. The motor drives the lead screw. A lead screw slide is slidably mounted on the support plate. The lead screw slide and the lead screw form a helical pair. A rack and pinion cylinder is provided on the lead screw slide. A rack is provided on the extension rod of the rack and pinion cylinder. The rack meshes with a control gear ring to drive the control gear ring to rotate.

[0012] Furthermore, a spring for providing elastic force is connected between the pressing telescopic shaft and the docking reinforcement cylinder, and the end of the pressing telescopic shaft facing the reinforcement pressing seat is a spherical end.

[0013] The beneficial effects of this invention compared with the prior art are: (1) The nozzle and the filling valve at the bottom of the tank are in a matching relationship. When they are docked, the nozzle docks with the docking reinforcement cylinder. The rack and pinion cylinder II controls the rack and pinion to mesh with the control gear ring. Then, the motor I works, the turntable rotates, the lead screw slide slides, and the rack and pinion moves to drive the control gear ring to rotate, so that the gear and the reinforcement clamping seat rotate. The contact part rotates to the bottom of the clamping telescopic shaft, and the spherical end of the clamping telescopic shaft presses against the contact part to achieve a reinforcement effect; (2) After the rack and pinion disengage from the control gear ring, the position of the gear and the reinforcement clamping seat will not change due to the limiting effect of the torsion spring, that is, it is in a stable state, which facilitates the subsequent reinforcement operation; (3) The nozzle deflects to the maintenance and cleaning mechanism. Below, the maintenance moving belt moves through the belt motor, which in turn moves the moving seat. The maintenance motor drives the washing part to rotate. The nozzle is located inside the washing part to maintain and clean the nozzle. Furthermore, the position can be adjusted so that the impact plate is above the nozzle. Water is sprayed from the nozzle onto the impact plate, so that the uniformity of the sprayed water can be observed and the water pressure can be corrected. When the water hits the impact plate, the pressure-sensitive element can output a feedback pressure change signal. The water pressure and uniformity are important indicators for adding water to the tank and will affect the cooling effect during filling. (4) The present invention adopts a detachable connection form to realize the connection between the pipeline and the tank, which can conveniently maintain the pipeline nozzle, perform maintenance operations more intuitively, and improve safety.

A moving seat 601 is attached to the maintenance moving belt 6. A maintenance motor 13 is set on the moving seat 601. A washing part 14 is set on the output shaft of the maintenance motor 13 for washing and maintaining the nozzle 37.

[0027] A pressure cylinder 15 is installed on the movable base 601. An impact plate 16 is telescopically installed on the telescopic rod of the pressure cylinder 15. A pressure-sensitive element 1601 for outputting feedback pressure change signals is connected between the impact plate 16 and the telescopic rod of the pressure cylinder 15. The nozzle 37 sprays water towards the impact plate 16 to observe and verify the uniformity and pressure of the water spray.

[0028] The inlet end of the filling pump 8 is equipped with a filling connecting pipe 4 and an antifreeze filler 3. The antifreeze filler 3 is connected to the filling connecting pipe 4 for transmitting and replenishing antifreeze. The outlet end of the filling pump 8 is equipped with a control electric cylinder 9. The telescopic rod of the control electric cylinder 9 is connected to the mounting plate 11 for controlling the movement of the mounting plate 11. The mounting plate 11 is connected to the outlet end of the filling pump 8 through a connecting hose 10. A rack electric cylinder 18 is provided between each mounting plate 11. A rack 19 is provided on the telescopic rod of the rack electric cylinder 18. The rack 19 meshes with the turntable 17.

[0029] A monitoring mounting bracket 20 is provided on the outside of the docking transmission pipe 12. One end of the monitoring mounting bracket 20 is fixedly connected to the turntable 17. A monitoring control motor 21 is provided on the monitoring mounting bracket 20 to drive the monitoring moving belt 22. The monitor 23 is used to monitor the surface cracks and leaks of the docking transmission pipe 12.

[0030] The reinforcement mechanism includes a control gear ring 35 rotatably mounted on the mounting base 34, and a control mechanism is provided on the outside of the docking reinforcement cylinder 31 for driving and controlling the reinforcement mechanism; a connecting shaft 41 is connected to the reinforcement clamping seat 38, the connecting shaft 41 is rotatably mounted on the mounting base 34, and a gear 36 is provided at the end of the connecting shaft 41, the gear 36 meshing with the control gear ring 35; a torsion spring 40 is sleeved on the connecting shaft 41, and the two ends of the torsion spring 40 are respectively connected to the mounting base 34 and the reinforcement clamping seat 38; a spring 33 for providing elastic force is connected between the clamping telescopic shaft 32 and the docking reinforcement cylinder 31, and the end of the clamping telescopic shaft 32 facing the reinforcement clamping seat 38 is a spherical end.

[0031] The control mechanism includes a support plate 25 connected to the docking reinforcement cylinder 31. A motor 26 and a lead screw 27 are mounted on the support plate 25. The motor 26 drives the lead screw 27. A lead screw slide 28 is slidably mounted on the support plate 25. The lead screw slide 28 and the lead screw 27 form a helical pair. A rack and pinion cylinder 29 is mounted on the lead screw slide 28. A rack 30 is mounted on the telescopic rod of the rack and pinion cylinder 29. The rack 30 meshes with a control gear ring 35 to drive the control gear ring 35 to rotate.

[0032] The operating principle is as follows: Water is added by connecting the filling pipe 4 to the external fire pipeline. In low-temperature environments, antifreeze can be added through the antifreeze injector 3 to prevent the pipeline from freezing. Specifically, the water source is transmitted to the docking transmission pipe 12 through the filling pump 8, and then injected into the tank 2 through the nozzle 37 on the docking transmission pipe 12. The nozzle 37 and the filling valve 24 at the bottom of the tank 2 are in a cooperative relationship. During docking, the nozzle 37 docks with the docking reinforcement cylinder 31. The rack and pinion cylinder 29 controls the rack 30 to mesh with the control gear ring 35. Then, the motor 26 works, the turntable 17 rotates, the lead screw slide 28 slides, and the rack 30 moves to drive the control gear ring 35 to rotate, so that the gear 36 and the reinforcement clamping seat 38 rotate. The contact part 39 rotates to the bottom of the clamping telescopic shaft 32, and the spherical end of the clamping telescopic shaft 32 presses against the contact part 39 to achieve a reinforcement effect.

[0033] When disengaging from the docking, first release the aforementioned reinforcement operation. It should be noted that after rack 2 30 disengages from control gear ring 35, the torsion spring 40 limits the position of gear 36 and reinforcement clamping seat 38, ensuring they remain stable and facilitating subsequent reinforcement operations. Control the installation plate 11 to move via control electric cylinder 9, which in turn moves the docking transmission pipe 12, causing nozzle 37 to disengage from docking reinforcement cylinder 31. Then, control rack 19 to move via rack electric cylinder 18, causing turntable 17 to rotate, which in turn rotates docking transmission pipe 12, causing nozzle 37 to deflect for maintenance.

[0034] During maintenance, the nozzle 37 is deflected below the maintenance and cleaning mechanism. The belt motor 7 operates, causing the maintenance moving belt 6 to move, which in turn moves the moving seat 601. The maintenance motor 13 operates, driving the washing section 14 to rotate. The nozzle 37 is located inside the washing section 14 to perform maintenance and cleaning on the nozzle 37. Furthermore, the position can be adjusted so that the impact plate 16 is above the nozzle 37. Water is sprayed from the nozzle 37 onto the impact plate 16, allowing observation of the uniformity of the sprayed water and correction of the water pressure. When the water hits the impact plate 16, the pressure-sensitive element 1601 can output a feedback signal of pressure change. The water pressure and uniformity are important indicators for adding water to the tank 2 and affect the cooling effect during filling.

[0035] During operation, the monitoring and control motor 21 can be operated, and the monitoring moving belt 22 can drive the monitor 23 to move along the outside of the docking transfer pipe 12 to monitor the docking transfer pipe 12, that is, to monitor whether there are cracks or leaks on the surface of the docking transfer pipe 12, so as to issue an alarm and facilitate the operator to carry out maintenance in a timely manner.
