Description

Technical Field

[0001] This invention relates to the field of aviation operation support equipment technology, specifically to a water tank replenishment device for aviation operation support. Background Technology

[0002] Airport fire trucks typically replenish their water tanks using fire hydrants. However, existing fire hydrants are usually equipped with protective devices on their outer sides. These devices can reduce the efficiency of connecting the fire truck and the hydrant when water replenishment is needed. A water tank replenishment device for aviation operation support, application number 2021201767317, includes a mounting base plate with four symmetrically arranged connecting columns on its upper end. A downwardly movable protective railing facilitates quick connection between the fire truck and the fire hydrant; a support fixing plate facilitates the fixing of the protective railing; and a clamping block facilitates the fixing of the support fixing plate.

[0003] Although this device possesses the aforementioned advantages, it still suffers from the following drawbacks in practical use:

[0004] 1) The device uses springs on both sides of the support plate and clamping blocks to abut against the wall of the fixing groove, thereby achieving the support and fixation of the protective bar by the fixing plate. However, the springs can only provide one-way abutment force, and the clamping blocks do not have a limiting measure with the protective bar, resulting in limited support and fixation effect. This can easily cause the fixing plate to detach from the protective bar, affecting the protection effect.

[0005] 2) When the device supports and fixes the protective bar with the fixing plate, it is necessary to manually rotate the fixing plate and compress the springs and clamping blocks on both sides into the groove on the side of the fixing plate. The protective bar also needs to be lifted and then the fixing plate needs to be rotated into the fixing groove to support and fix the protective bar. This process is time-consuming, laborious and inefficient. At the same time, when using fire hydrants, the protective bar and fixing plate also need to be lowered manually, which is inconvenient for the use of fire hydrants.

[0006] Therefore, it is necessary to address the aforementioned problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a water tank replenishment device for aviation operation support. It solves the problems of existing aviation operation support water tank replenishment devices, which use fixed plates to support and fix protective poles to protect fire hydrants.

[0016] Beneficial effects

[0017] This invention provides a water tank replenishment device for aviation operation support. Compared with the prior art, it has the following advantages:

[0018] (1) By setting up a protective mechanism, the screw rod drives the screw sleeve to rise and fall, so that the connecting block follows the rise and fall on the inclined rod, and the connecting column and slider drive the frame to rise and fall. First, the frame is kept stable, which enhances the stability. At the same time, the lifting motor is used to drive the frame, which improves the efficiency of the frame's rise and fall. The screw rod, inclined rod and telescopic rod form a fence to protect the fire hydrant from the outside, which further enhances the safety of the frame in protecting the fire hydrant.

[0019] (2) By setting up a cleaning component, the surface of the screw can be cleaned by the contact between the brush and the screw during the rotation of the screw and the lifting of the sleeve. This prevents dust, impurities and rust on the surface from affecting the lifting of the sleeve, thus affecting the lifting of the frame and the use of the fire hydrant. In addition, by setting multiple sets of brushes on the circular plate and adjusting them by rotating the motor, the problem of needing to replace the brushes repeatedly after they wear out can be avoided.

[0020] (3) By setting up an oil supply unit, the lubricating oil inside the oil tank can be pumped into the oil control box for quantitative replenishment. At the same time, the lubricating oil is pumped out by the pump, so that the brush bristles can absorb the lubricating oil, thereby improving the cleaning efficiency. It can also protect the lead screw and brush bristles, prevent the lead screw from being corroded, and slow down the aging speed of the brush bristles, thus improving the service life of the equipment.

[0021] (4) By setting up a frequency control module, the external environment can be sensed by connecting an external temperature sensor and a humidity sensor. This allows for the selection of gearboxes with different transmission ratios based on the actual environmental conditions, thereby changing the frequency of the drive motor driving the rotating rod to control the oil supply frequency. This allows for the maintenance of the lead screw and brush bristles based on the actual environmental conditions.

[0022] (5) By setting a trigger module, when the amount of oil pumped into the oil control box from the oil drum is insufficient, the gravity of the lubricating oil cannot fully press down the spring rod, causing the slide bar to be unable to fully connect with the vertical groove, resulting in the slide bar being unable to shield the air inlet pipe and the air whistle end, so that the air pumped in by the fan is discharged through the air whistle and forms a whistle sound to alarm, so that the oil drum and oil control box can be replenished with enough lubricating oil in real time.

The outer surface of the screw sleeve 4 is fixedly connected to the connecting rod 10. The two sides of the outer surface of the connecting rod 10 are slidably connected to the connecting blocks 9. The sides are slidably connected to the main body of the connecting blocks 9 on both sides. A groove 11 is provided on the outer surface of the frame 2, and a slider 12 is movably connected inside the groove 11. The slider 12 is made of a pressure-resistant, wear-resistant, and corrosion-resistant material. A connecting column 13 is fixedly connected to the outer surface of the slider 12, and the outer surface of the connecting column 13 is embedded and movably connected to the main body of the connecting block 9. A telescopic rod 14 is fixedly connected to the outer surface of the frame 2. The telescopic rod 14 is made of a pressure-resistant, wear-resistant, and corrosion-resistant material, and is fence-shaped to improve the protection performance of the fire hydrant. One end of 14 is fixedly connected to the outer surface of the base 1. By setting a protective mechanism, the screw rod 3 drives the screw sleeve 4 to rise and fall, so that the connecting block 9 follows the rise and fall on the inclined rod 8. The connecting column 13 and the slider 12 drive the frame 2 to rise and fall. First, the frame 2 is kept stable, which enhances the stability. At the same time, the lifting motor 7 is used to drive the frame 2, which improves the efficiency of the frame 2's rise and fall. The screw rod 3, the inclined rod 8 and the telescopic rod 14 form a fence to protect the fire hydrant from the outside, which further enhances the safety of the frame 2 in protecting the fire hydrant.

[0035] Example 2, based on Example 1:

[0036] The cleaning component 5 includes a connecting frame 51, the outer surface of which is fixedly connected to the outer surface of the screw sleeve 4. A rotary motor 52 is fixedly connected to the outer surface of the connecting frame 51. The rotary motor 52 is electrically connected to an external control circuit. The output end of the rotary motor 52 is rotatably connected to the body of the connecting frame 51. A circular plate 53 is fixedly connected to the output end of the rotary motor 52. The circular plate 53 is made of a pressure-resistant, wear-resistant, and corrosion-resistant material and is hollow inside. The outer surface of the circular plate 53 is movably connected to the outer surface of the connecting frame 51. An oil supply pipe 54 is movably connected through the interior of the circular plate 53. One end of the oil supply pipe 54 is rotatably connected through the interior of the circular plate 53, and a sealing measure is provided at the connection. An oil supply unit 55 is provided outside the oil supply pipe 54. A retaining ring 56 is fixedly connected to the outer surface of the oil supply pipe 54. The outer surface of the retaining ring 56 is fixedly connected to the outer surface of the bracket 6. The interior of the screw rod 3 is connected by a vertical pipe 57. The body of the vertical pipe 57 has a through hole 58. The inside of the through hole 58 is equipped with bristles 59. The bristles 59 are made of a material with a certain rigidity and adsorption capacity and are fixedly connected to the inside of the through hole 58. At the same time, one end extends through the inside of the vertical pipe 57 to the inside of the circular plate 53 for fixation. The outer surface of the bristles 59 is movably connected to the outer surface of the screw rod 3. By setting a cleaning component 5, when the screw rod 3 rotates and drives the screw sleeve 4 to rise and fall, the surface of the screw rod 3 can be cleaned by the contact between the bristles 59 and the screw rod 3. This prevents dust, impurities and rust on its surface from affecting the rising and falling of the screw sleeve 4, thereby affecting the rising and falling of the frame 2 and the use of the fire hydrant. Furthermore, by setting multiple sets of bristles 59 on the circular plate 53 and adjusting them by rotating the motor 52, the problem of repeatedly replacing the bristles 59 after they wear out can be avoided.

[0037] Example 3, based on Example 2:

[0038] The oil supply unit 55 includes an oil control box 551, which is made of a pressure-resistant, wear-resistant, and corrosion-resistant material. The outer surface of the oil control box 551 is fixedly connected to the outer surface of the frame 2. A frequency control module 552 is installed on the outside of the oil control box 551. A sliding plate 553 is movably connected inside the oil control box 551. The sliding plate 553 is made of a pressure-resistant, wear-resistant, and well-sealed material. A trigger module 554 is installed on the outside of the sliding plate 553. An oil supply pipe 555 runs through the inside of the oil control box 551. One end of the oil supply pipe 555 is connected to one end of the oil delivery pipe 54. A pump 556 is fixedly connected to the outer surface of the sliding plate 553. The pump 556 is electrically connected to an external control circuit. A bellows 557 is connected to the output end of the pump 556. The bellows 557 can extend and retract to adapt to the lifting and lowering of the pump 556. One end of the bellows 557 is connected to the other end of the oil supply pipe 555. A spring rod 558 is fixedly connected to the other side of the outer surface. The spring rod 558 is made of a pressure-resistant, wear-resistant and fatigue-resistant material. One end of the spring rod 558 is fixedly connected to the inside of the oil control box 551. An oil inlet pipe 559 runs through the inside of the oil control box 551. One end of the oil inlet pipe 559 runs through the oil tank 5510. The oil tank 5510 contains liquid lubricating oil and an additional pump 556. The outer surface of the oil tank 5510 is fixedly connected to the outer surface of the frame 2. By setting up an oil supply unit 55, the lubricating oil inside the oil tank 5510 is pumped into the oil control box 551 for quantitative replenishment. At the same time, the lubricating oil is pumped out by the pump 556, so that the bristles 59 can absorb the lubricating oil, thereby improving the cleaning efficiency. At the same time, it can protect the lead screw 3 and the bristles 59, prevent the lead screw 3 from being corroded, and slow down the aging rate of the bristles 59, thereby extending the service life of the equipment.

[0039] Example 4, based on Example 3:

[0040] The frequency control module 552 includes a slide rail 5521. A linear motor 5522 is slidably connected to the outer surface of the slide rail 5521. The linear motor 5522 is electrically connected to an external control circuit and has a self-locking function. A gearbox 5523 is fixedly connected to the outer surface of the linear motor 5522. Multiple gearboxes 5523 are provided, each with a different gear ratio. A drive motor 5524 and a rotating rod 5525 are movably connected to both ends of the gearbox 5523, respectively. The drive motor 5524 is electrically connected to an external control circuit, and the control circuit is externally connected to a temperature sensor and a humidity sensor. The outer surface of the drive motor 5524 is fixedly connected to the outer surface of the oil control box 551. A fixed plate 5526 is rotatably connected to the outer surface of the rotating rod 5525. The fixed plate 5526 and the rotating rod 5525 are connected by rotational damping to prevent the rotating rod 5525 from rotating. The outer surface of the fixed plate 5526 is fixedly connected to the outer surface of the oil control box 551. One end of the rotating rod 5525... A tachometer 5527 is fixedly connected to the end of the gearbox 5523. The tachometer 5527 is an existing speed sensor and is electrically connected to an external control circuit. It sets how many revolutions the rotating rod 5525 makes, which means that the pump 556 pumps oil once. The ends of the rotating rod 5525 and the drive motor 5524 are provided with slots 5528. The slots 5528 on both sides are fitted with plates 5529. The plates 5529 are made of pressure-resistant, wear-resistant and corrosion-resistant materials. The outer surfaces of the plates 5529 on both sides are fixedly connected to the two ends of the gearbox 5523. By setting a frequency control module 552 and connecting external temperature and humidity sensors, the external environment can be sensed. According to the actual environmental conditions, different gearbox ratios of the gearbox 5523 can be selected for use, thereby changing the frequency of the drive motor 5524 driving the rotating rod 5525 to control the oil supply frequency. Thus, the lead screw 3 and brush bristles 59 can be maintained according to the actual environmental conditions.

[0041] Example 5, based on Example 4:

[0042] The trigger module 554 includes a fixed post 5541, one end of which can limit the sliding plate 553. The outer surface of the fixed post 5541 is fixedly connected to the body of the oil control box 551. A vertical groove 5542 is formed on the outer surface of the fixed post 5541. A sliding strip 5543 is slidably connected inside the vertical groove 5542. The sliding strip 5543 is made of a pressure-resistant, wear-resistant and well-sealing material. The outer surface of the sliding strip 5543 is fixedly connected to the outer surface of the sliding plate 553. A whistle 5544 is connected through the vertical groove 5542. A sound control device can be installed on the outside of the whistle 5544 to enable the external oil supply equipment to automatically replenish oil to the oil tank 5510 or the oil control box 551. An air inlet pipe 55 is connected through the vertical groove 5542. 45. A fan 5546 is installed inside the air intake pipe 5545. The fan 5546 is electrically connected to the external control circuit. A filter screen 5547 is installed inside one end of the air intake pipe 5545. By setting a trigger module 554, when the amount of oil pumped into the oil control box 551 by the oil tank 5510 is insufficient, the gravity of the lubricating oil cannot fully press down the spring rod 558, causing the slide bar 5543 to be unable to fully connect with the vertical groove 5542. As a result, the slide bar 5543 cannot block one end of the air intake pipe 5545 and the air whistle 5544, so that the air pumped in by the fan 5546 is discharged through the air whistle 5544 and forms a whistle to alarm, so that the oil tank 5510 and the oil control box 551 can be replenished with sufficient lubricating oil in real time.

[0043] Example 6: This example combines Examples 1 to 5. The lifting motor 7 drives the frame 2 to rise and fall, which can improve the efficiency of fire hydrant protection and use. At the same time, liquid lubricating oil is used to maintain the brush bristles 59 and the lead screw 3, which improves the service life of the equipment.

[0044] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0045] At work,

[0046] Firefighting water replenishment: When it is necessary to use fire hydrants for water replenishment, the lifting motor 7 drives the lead screw 3 to rotate. Through the threaded connection between the lead screw 3 and the screw sleeve 4, and the connection between the screw sleeve 4 and the connecting block 9 through the connecting rod 10, the screw sleeve 4 drives the connecting block 9 to descend synchronously along the inclined rod 8. Since the connecting block 9 is connected to the slider 12 through the connecting column 13, the slider 12 moves closer to each other inside the slide groove 11, and drives the frame 2 to descend, so that the frame 2 is no longer obstructing the fire hydrant outlet. Then, the fire hydrant can be used to replenish water for the fire truck, so as to facilitate aviation operation support.

[0047] Lubrication and maintenance: During the process of the lead screw 3 driving the screw sleeve 4 to descend, the connecting frame 51 drives the circular plate 53 and the brush bristles 59 to descend as well. Through the contact between the brush bristles 59 and the lead screw 3 and the rotation of the lead screw 3, the brush bristles 59 clean the surface of the lead screw 3. During the cleaning process, the pump 556 pumps the lubricating oil inside the oil control box 551 into the circular plate 53, and through the vertical pipe 57 and the connecting hole 58, the brush bristles 59 absorb the lubricating oil, thereby applying the lubricating oil to the surface of the lead screw 3, which can clean and lubricate the lead screw 3, as well as wet and protect the brush bristles 59. At the same time, when the brush bristles 59 wear out and affect the cleaning effect, the rotary motor 52 drives the circular plate 53 to rotate, so that the adjacent set of vertical pipes 57 drives another set of brush bristles 59 to contact the lead screw 3 and perform cleaning work, avoiding the need to replace the brush bristles 59 repeatedly after they wear out.

[0048] Frequency control and replenishment: During the cleaning process or when stationary, the temperature sensor and humidity sensor monitor the external environment. Then, based on the external environment, a gearbox 5523 with an appropriate transmission ratio is selected for transmission. Subsequently, the linear motor 5522 slides on the slide rail 5521 and drives the corresponding gearbox 5523 to move between the rotating rod 5525 and the drive motor 5524. At the same time, the clamping plate 5529 at the end of the gearbox 5523 is engaged in the slot 5528, and the corresponding gearbox 5523 can then transmit power and drive the rotating rod 5525 to rotate. Meanwhile, the tachometer 5527 senses the number of rotations of the rotating rod 5525. When the number of rotations of the rotating rod 5525 reaches the rated value, the pump 556 pumps the lubricating oil inside the oil control box 551 into the circular plate 53 to replenish the oil for the bristles 59, thereby facilitating the maintenance of the bristles 59 and the lead screw 3.

[0049] Oil shortage alarm: After pump 556 replenishes lubricating oil to brush 59, oil is replenished to the oil control box 551 through oil tank 5510 or external oil supply equipment. When the oil level in the oil control box 551 is insufficient, slide plate 553 cannot fully press down spring rod 558, causing slide bar 5543 to fail to fully connect with vertical groove 5542, and failing to shield one end of air intake pipe 5545 and air whistle 5544. Consequently, the air pumped in by fan 5546 is blocked. The vertical groove 5542 and the air whistle 5544 are discharged, and the air whistle 5544 makes a sound so that the staff can hear it and replenish the oil in the oil tank 5510 and the oil control box 551 in time. Alternatively, the sound monitoring device can sense the whistle sound and control the external oil supply device to automatically replenish the oil tank 5510 or the oil control box 551, thereby ensuring that the oil control box 551 and the oil tank 5510 have sufficient oil to avoid affecting the maintenance of the bristles 59 and the lead screw 3.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
