Description

Technical Field

[0001] The invention relates to the field of wind resistance and deflection, and in particular to a wind-adaptive wind direction-adaptive wind-resistant deflector mechanical device for a railway arch bridge. Background Art

[0002] In modern railway bridge construction, railway arch bridges are widely used for their beautiful shapes and good spanning capacity. However, with the continuous increase in bridge spans and the increasing complexity of structural forms, the problem of bridge wind resistance stability under strong winds has become increasingly prominent. Strong winds not only affect the safe operation of trains, but may also cause fatigue damage to bridge structures and even cause catastrophic accidents. Therefore, the installation of wind deflectors to improve the wind environment around bridges and reduce the adverse effects of wind loads on bridges has become an important means to ensure the safe operation of railway arch bridges.

[0003] The existing railway arch bridge wind-resistant deflector is not convenient for adjusting the diversion direction and diversion angle according to the external wind direction, resulting in poor diversion and wind-resistant effect, weak adaptability, and inconvenient use for railway arch bridges in different locations. In addition, after long-term use, the guide blades in the existing technology are prone to adhesion of debris, affecting the diversion effect and cannot be cleaned in time, which needs to be improved. For this reason, we propose a mechanical device for railway arch bridge wind-resistant deflector with adaptive wind direction. Summary of the Invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a device that is convenient for adjusting the diversion direction and diversion angle according to the external wind direction; another purpose of the present invention is to provide a device that can clean up debris adhered to the blades in a timely manner.

[0005] The cam is fixedly mounted on the outside of the gear train and is connected to the drive gear of the cam, and the cam is connected to the transmission gear of the cam by the spring.

[0006] Further, the upper surface of the base is fixedly connected with a liquid pump, the left end of the output end of the liquid pump is fixedly connected with an adapter, and the left side of the adapter is integrally formed with a plurality of docking heads.

[0007] Further, the input end of the liquid pump is fixedly connected with a collecting box, the inside of the collecting box is fixedly connected with a baffle ring, and the upper side of the baffle ring is provided with a filter screen.

[0008] Further, the upper surface of the guide vane is fixedly connected with a flushing nozzle, the rear surface of the flushing nozzle is integrally formed with a docking hose, and the docking hose is matched with the docking head.

[0009] Further, the outer side wall of the rotating rod and located outside the two racks is sleeved with a protective sleeve, the top and bottom of the protective sleeve are fixedly connected with the opposite sides of the two annular rings, the outer side wall of the protective sleeve is provided with vertical grooves on the outer sides of the shaft columns on both sides, and the vertical grooves are slidably connected with the shaft columns.

[0010] Further, the outer side wall of the protective sleeve is provided with a shielding strip near the vertical groove, the shielding strip is located outside the shaft column and is rotatably connected with the shaft column through a rotating shaft.

[0011] Further, the top end of the rotating rod is fixedly connected with a wind direction sensor.

[0012] Beneficial effect: The wind direction sensor can monitor the change of wind direction in real time, the control system can drive the motor to rotate the rotating rod, so that the whole device can be automatically adjusted to the wind direction, which breaks through the limitation of the traditional guide plate that cannot be dynamically adjusted according to the wind direction, avoids the failure of wind resistance caused by the change of wind direction, and is suitable for railway arch bridges in different positions;

[0013] The electric push rod pushes the connecting plate, drives the annular ring and the rack to move, and drives the shaft column to rotate through the gear, so as to adjust the angle of the guide vane, change the fixed angle design of the traditional guide plate, and avoid the concentration of wind load or the guide effect caused by unreasonable angle;

[0014] The liquid pump draws water from the collecting box, sprays water flow through the flushing nozzle to clean the guide vane, solves the problem that the traditional guide vane is adhered with sundries (such as dust, bird droppings, fallen leaves, etc.) after long-term use, and causes the guide efficiency to decrease;

[0015] The collecting box collects external rainwater, filters the rainwater through the baffle ring and the filter screen, and stores the rainwater, so as to provide water source for the flushing system, avoid impurities from blocking the motor and other precision components, use natural rainwater as cleaning water source, and reduce water resource waste;

[0016] The protective sleeve wraps the internal gears and racks to prevent direct erosion by rain and dust. The exposed mechanical parts of traditional devices are easily affected by the external environment (such as rust and jamming), which can lead to transmission failure. Physical protection can reduce the wear and tear of mechanical parts, lower the maintenance frequency, and improve the reliability of the device in harsh environments (such as rainy and windy areas).

A rotating rod 2 is rotatably connected to the center of the upper surface of the base 1 via a rotating shaft. The outer wall of the rotating rod 2 is rotatably connected to multiple shaft columns 3 via a rotating shaft. The outer wall of the shaft column 3 is fixedly connected to a deflector 4. The outer wall of the shaft column 3 is fixedly connected to a gear 5 near the deflector 4. The outer wall of the rotating rod 2 is located above and below the multiple gears 5 and is slidably connected to a ring 6. Two racks 7 are fixedly connected between the two rings 6. The two racks 7 are respectively meshed with the plurality of gears 1 5. A gear 2 8 is fixedly connected to the lower side wall of the rotating rod 2. A motor 9 is fixedly connected to the right side of the lower surface of the base 1. A gear 3 10 is fixedly connected to the top of the output shaft of the motor 9. The gear 2 8 is meshed with the gear 3 10. An electric push rod 11 is fixedly connected to the left side of the upper surface of the base 1. The top of the output end of the electric push rod 11 is fixedly connected to a connecting plate 12. The right side of the connecting plate 12 is rotatably connected to the ring 6 located at the lower side of the rotating rod 2 through a rotating shaft.

[0027] A liquid pump 13 is fixedly connected to the rear of the upper surface of the base 1. The left end of the output end of the liquid pump 13 is fixedly connected to an adapter 14. A plurality of docking joints 15 are integrally formed on the left side of the adapter 14.

[0028] The rear end of the input end of the liquid pump 13 is fixedly connected to a collection box 16, a retaining ring 17 is fixedly connected to the interior of the collection box 16, and a filter screen 23 is provided above the retaining ring 17;

[0029] A flushing nozzle 18 is fixedly connected to the rear of the upper surface of the guide plate 4. A docking hose 19 is integrally formed on the rear surface of the flushing nozzle 18. The docking hose 19 is adapted to the docking joint 15.

[0030] A protective sleeve 20 is sleeved on the outer side of the rotating rod 2 and located outside the two racks 7. The top and bottom of the protective sleeve 20 are fixedly connected to the opposite sides of the two rings 6 respectively. The outer side of the protective sleeve 20 is provided with vertical grooves 21 on the outer sides of the multiple shaft columns 3 on both sides. The vertical grooves 21 are slidably connected to the shaft columns 3.

[0031] A shielding strip 22 is provided on the outer wall of the protective sleeve 20 near the vertical groove 21. The shielding strip 22 is located on the outer side of the shaft column 3 and is rotatably connected to the shaft column 3 via a rotating shaft.

[0032] The top of the rotating rod 2 is fixedly connected with a wind direction sensor 24;

[0033] (When the wind direction sensor 24 detects a change in the external wind direction, it transmits a signal to the control system, which starts the motor 9. The output shaft of the motor 9 drives the gear 3 10 to rotate. The gear 3 10 meshes with the gear 2 8, thereby driving the rotating rod 2 to rotate around the rotating shaft on the base 1, so that the entire device is adjusted to the windward direction;

[0034] At the same time, the control system activates the electric push rod 11. The output end of the electric push rod 11 pushes the connecting plate 12. The connecting plate 12 drives the ring 6 located on the outer side and lower side of the rotating rod 2 to slide on the rotating rod 2. The rack 7 between the two rings 6 moves accordingly. The rack 7 engages with the gear 1 5, driving the shaft column 3 to rotate, thereby causing the guide vane 4 to rotate around the rotating axis of the shaft column 3, adjusting the diversion angle to adapt to the wind direction;

[0035] During long-term use of the guide plate 4, if debris adheres to it, the control system can start the liquid pump 13, which pumps water from the collection box 16. The water enters the docking hose 19 through the adapter 14 and the docking joint 15, and is finally sprayed out from the flushing nozzle 18 to flush the guide plate 4.

[0036] The collection box 16 is used to collect external rainwater and filter it through the filter 23 to prevent the rainwater from mixing with impurities and clogging the motor 9;

[0037] The protective sleeve 20 on the outside of the rotating rod 2 can protect the internal gears, racks and other structures, and the vertical groove 21 on the protective sleeve 20 is slidably connected to the shaft column 3. When the shaft column 3 rotates, it drives the shielding bar 22 to rotate around the rotating axis, shielding the vertical groove 21 to prevent debris from entering the interior of the protective sleeve 20).

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
