Description

Technical Field

[0001] The utility model relates to the field of wind atomization, in particular to a device for reducing the rotation speed fluctuation of a fan blade during its rotation. Background Art

[0002] Wind atomization technology is driven by wind power and uses special equipment to disperse water into droplets and spray them into the atmosphere, and the mist flow relies on the airflow to achieve large-area transportation and drift. Wind atomization technology uses my country's abundant and exploitable wind resources and uses river and lake water, groundwater, reclaimed water, rainwater and other water sources as atomization media. It has strong technicality and wide applicability, and has broad application prospects in the fields of air pollution prevention and control, agricultural water-saving irrigation, regional ecological restoration, urban landscape design, etc.

[0003] The inventors have discovered that since wind atomization technology uses wind power to drive the atomization device, changes in wind speed will directly affect the atomization effect and efficiency. When the wind speed is too low, the fan blades may not be driven to rotate, resulting in poor atomization effect; when the wind speed is too high, it may cause the equipment to operate unstably or even cause damage. Utility Model Content

[0004] The utility model aims to provide a device for reducing the rotation speed fluctuation of a fan blade during its rotation, which can make the fan blade run stably and reduce the fluctuation when the wind speed changes.

[0005] The embodiment of the utility model is achieved as follows:

[0006] A device for reducing the rotation speed fluctuation of a fan blade during rotation, comprising a base, a mounting tube provided on the base, an atomizer provided on the mounting tube, a pressure water tank, a driving mechanism, a linkage mechanism and a stabilizing mechanism, wherein the driving mechanism drives the pressure water tank to work through the linkage mechanism, the pressure water tank supplies water to the atomizer, and the stabilizing mechanism is used to make the driving mechanism work stably;

[0007] The driving mechanism comprises a mounting rod, fan blades and a box body; the box body is mounted on the mounting tube, the mounting rod is rotatably inserted on the box body, and the fan blades are mounted on the end of the mounting rod.

[0008] The stabilizing mechanism comprises a slide slot, a counterweight block and a spring; the slide slot is arranged on the fan blade, the counterweight block is slidably installed in the slide slot, and the two ends of the spring are respectively connected to the side wall of the slide slot and the counterweight block.

[0009] Preferably, the linkage mechanism includes a turntable, an upper connecting rod, a lower connecting rod, and a limit bracket; the turntable is sleeved on the mounting rod, the upper connecting rod is rotatably connected to the side wall of the turntable, the lower connecting rod is rotatably connected to the upper connecting rod, the limit bracket is installed in the mounting tube, the lower connecting rod passes through the limit bracket, and the lower connecting rod is used to drive the pressure water tank to work.

[0010] Preferably, the pressure water tank includes a water cylinder, a piston, a water inlet valve, a drain valve, and a water inlet pipe; the water cylinder is embedded in the base, the piston is slidably installed in the water cylinder, the water inlet valve and the drain valve are both embedded in the side wall of the water cylinder, and the piston is connected to the lower connecting rod, the water inlet pipe is installed on the input end of the water inlet valve, and the water inlet of the atomizer is connected to the output end of the drain valve.

[0011] First, install the base on the ground and place the end of the water inlet pipe in the water; during normal operation, the wind blows the fan blades, which drive the installation rod to rotate through the fan blades, so that the upper connecting rod can be driven to reciprocate up and down through the turntable. At the same time, under the action of the limit bracket, the upper connecting rod drives the lower connecting rod to reciprocate up and down, so that the piston can reciprocate up and down in the water cylinder. When the piston moves up, the space below the piston in the water cylinder is in a negative pressure state. At this time, the water cylinder absorbs water from the water through the water inlet valve and the water inlet pipe. When the piston moves down, the water in the water cylinder is discharged from the drain valve under the joint action of the water inlet valve and the drain valve, so as to supply water to the atomizer.

[0012] When the wind force is too strong, under the action of centrifugal force, the counterweight slides along the slide to the end away from the mounting rod. At this time, according to the moment of inertia calculation formula I=mr^2, where m is the mass of the particle and r is the vertical distance from the particle to the axis of rotation, it can be seen that when the counterweight moves to the end of the slide away from the mounting rod, the moment of inertia of the fan blade increases, so the fan blade speed increases more slowly, thereby reducing the acceleration efficiency of the fan blade due to wind speed; when the fan blade slows down, the spring will pull the counterweight to slide in the direction close to the mounting rod, thereby reducing the moment of inertia of the fan blade, thereby increasing the acceleration efficiency of the fan blade due to wind speed; therefore, under the action of the counterweight, the fan blade speed fluctuation is small during rotation, and the power is stable, thereby making the atomizer output stable.

[0013] Preferably, mounting holes are evenly formed on the counterweight block, and balls are movably embedded in the mounting holes.

[0014] By providing the ball bearings, the friction force between the counterweight block and the side wall of the slide groove can be converted from sliding friction to rolling friction between the ball bearings and the side wall of the slide groove, thereby reducing the resistance of the counterweight block and ensuring that the counterweight block can move along the slide groove in time.

[0015] Preferably, the top wall and the bottom wall of the piston are both arc surfaces.

[0016] The contact area between the piston and the side wall of the water cylinder is reduced under the action of the arc surface, thereby reducing the resistance encountered by the piston during movement, thereby ensuring that the piston can move normally.

[0017] Preferably, a support sleeve is sleeved on the mounting rod, and a support rod is installed between the support sleeve and the box body.

[0018] Preferably, a filter screen is provided at the end of the water inlet pipe.

[0019] Preferably, an elastic rope is installed on the side wall of the filter screen located in the water inlet pipe, and a floating block is installed on the elastic rope.

[0020] When the water cylinder is absorbing water, the water flow hits the float, and the float moves with the water flow, thereby stretching the elastic rope. When the water cylinder stops absorbing water, the water flow stops hitting the float, and the elastic rope recovers and pulls the float to reset, thereby hitting the filter. The impurities on the surface of the filter are shaken off by the impact force, ensuring that the water cylinder can absorb water normally.

[0021] Preferably, the box body is rotatably mounted on the top of the mounting tube, a socket is provided on the top wall of the piston, a rotating rod is rotatably mounted in the socket, and the lower connecting rod is fixedly connected to the rotating rod.

[0022] Preferably, a guide plate is installed on the side wall of the box body, and the guide plate is parallel to the mounting tube.

[0023] When the wind direction changes, the guide plate can keep the fan blades facing the wind at all times, thereby ensuring that the fan blades can be driven by wind. Moreover, under the action of the rotating rod, the piston can move normally even if the fan blades and the box rotate, thereby ensuring that the atomizer can work normally.

[0024] The beneficial effects of the embodiments of the utility model are as follows: when the wind speed increases, the counterweight moves to the end of the slide slot away from the mounting rod. At this time, the rotational inertia of the fan blades increases, so the fan blade speed increases more slowly, thereby reducing the acceleration efficiency of the wind speed on the fan blades; when the fan blades slow down, the spring will pull the counterweight to slide in the direction close to the mounting rod, thereby reducing the rotational inertia of the fan blades, thereby increasing the acceleration efficiency of the wind speed on the fan blades and avoiding a rapid decrease in the fan blade speed; therefore, under the action of the counterweight, the fan blade speed fluctuation is smaller during rotation, the power is stable, and the atomizer has a stable output.

[0040] The driving mechanism includes a mounting rod 5 , a fan blade 6 , and a box body 7 ; the box body 7 is mounted on the mounting tube 2 , the mounting rod 5 is rotatably inserted on the box body 7 , and the fan blade 6 is mounted on the end of the mounting rod 5 .

[0041] The stabilizing mechanism includes a slide groove 8, a counterweight block 9, and a spring 10; the slide groove 8 is provided on the fan blade 6, the counterweight block 9 is slidably installed in the slide groove 8, and the two ends of the spring 10 are respectively connected to the side wall of the slide groove 8 and the counterweight block 9.

[0042] The linkage mechanism includes a turntable 11, an upper linkage rod 12, a lower linkage rod 13, and a limit bracket 14; the turntable 11 is sleeved on the mounting rod 5, the upper linkage rod 12 is rotatably connected to the side wall of the turntable 11, the lower linkage rod 13 is rotatably connected to the upper linkage rod 12, the limit bracket 14 is installed in the mounting tube 2, the lower linkage rod 13 passes through the limit bracket 14, and the lower linkage rod 13 is used to drive the pressure water tank 4 to work.

[0043] The pressure water tank 4 includes a water cylinder 401, a piston 402, a water inlet valve 403, a drain valve 404, and a water inlet pipe 405; the water cylinder 401 is embedded in the base 1, the piston 402 is slidably installed in the water cylinder 401, the top wall and the bottom wall of the piston 402 are both arc surfaces, the water inlet valve 403 and the drain valve 404 are both embedded in the side wall of the water cylinder 401, and the piston 402 is connected to the lower connecting rod 13, the water inlet pipe 405 is installed on the input end of the water inlet valve 403, and the water inlet of the atomizer 3 is connected to the output end of the drain valve 404.

[0044] The counterweight block 9 is evenly provided with mounting holes, and balls 15 are movably embedded in the mounting holes.

[0045] The working principle of a device for reducing the rotation speed fluctuation of a fan blade during rotation is as follows: first, the base 1 is installed on the ground, and the end of the water inlet pipe 405 is placed in the water; during normal operation, the wind blows the fan blade 6, and under the support of the support sleeve 16 and the support rod 17, the installation rod 5 can be prevented from having a tendency to tilt, so that the installation rod 5 is driven to rotate by the fan blade 6, so that the upper connecting rod 12 can be driven to reciprocate up and down through the turntable 11. At the same time, under the action of the limit bracket 14, the upper connecting rod 12 drives the lower connecting rod 13 to reciprocate up and down, and under the action of the arc surface The contact area between the piston 402 and the side wall of the water cylinder 401 is reduced, thereby reducing the resistance encountered by the piston 402 during movement, so that the piston 402 can make up and down reciprocating motion in the water cylinder 401. When the piston 402 moves up, the space below the piston 402 in the water cylinder 401 is in a negative pressure state. At this time, the water cylinder 401 absorbs water from the water through the water inlet valve 403 and the water inlet pipe 405. When the piston 402 moves down, the water in the water cylinder 401 is discharged from the drain valve 404 under the joint action of the water inlet valve 403 and the drain valve 404, thereby supplying water to the atomizer 3.

[0046] By setting the ball 15, the friction between the counterweight block 9 and the side wall of the slide groove 8 can be converted from sliding friction to rolling friction between the ball 15 and the side wall of the slide groove 8, thereby reducing the resistance of the counterweight block 9 and ensuring that the counterweight block 9 can move along the slide groove 8 in time; when the wind force is strong, under the action of centrifugal force, the counterweight block 9 slides along the slide groove 8 to the end away from the mounting rod 5. At this time, according to the moment of inertia calculation formula I=mr^2, where m is the mass of the particle and r is the vertical distance from the particle to the rotating axis, it can be known that the counterweight block 9 moves to the slide groove 8 When it is away from one end of the mounting rod 5, the rotational inertia of the fan blade 6 increases, so the speed of the fan blade 6 increases more slowly, thereby reducing the acceleration efficiency of the wind speed on the fan blade 6; when the fan blade 6 slows down, the spring 10 will pull the counterweight block 9 to slide in the direction close to the mounting rod 5, thereby reducing the rotational inertia of the fan blade 6, thereby increasing the acceleration efficiency of the wind speed on the fan blade 6 and avoiding the fan blade 6 from decelerating too quickly; therefore, under the action of the counterweight block 9, the speed fluctuation of the fan blade 6 during the rotation process is small, the power is stable, and the atomizer 3 has a stable output.

[0047] Second embodiment

[0050] The box body 7 is rotatably mounted on the top of the mounting tube 2 . A plug hole is provided on the top wall of the piston 402 . A rotating rod 21 is rotatably mounted in the plug hole. The lower connecting rod 13 is fixedly connected to the rotating rod 21 .

[0051] A guide plate 22 is installed on the side wall of the box body 7 , and the guide plate 22 is parallel to the installation pipe 2 .

[0052] The working principle of a device for reducing the rotation speed fluctuation of a fan blade during rotation is as follows: during the water absorption process of a water cylinder 401, the water flow impacts the floating block 20, and the floating block 20 moves with the water flow, thereby stretching the elastic rope 19; when the water cylinder 401 stops absorbing water, the water flow stops impacting the floating block 20, and the elastic rope 19 recovers and pulls the floating block 20 to reset, thereby impacting the filter screen 18, and the impurities on the surface of the filter screen 18 are shaken off by the impact force, thereby ensuring that the water cylinder 401 can absorb water normally.

[0053] When the wind direction changes, under the action of the guide plate 22, the fan blades 6 can always face the wind directly, thereby ensuring that the fan blades 6 can be driven by the wind. Under the action of the rotating rod 21, even if the fan blades 6 and the box body 7 rotate, the piston 402 can move normally, ensuring that the atomizer 3 can work normally.
