The working process is as follows: in use, referring to fig. 2, when the liquid level of the working tank 5 is lower than the first critical liquid level line 5a, the first connecting rod 231 is driven to descend by the descending of the float 23, and further drives the second connecting rod 232 to descend so that the switching wheel 22 rotates counterclockwise, so that the second gear 221 and the first gear 213 of the switching wheel 22 are engaged to drive the switching rod 21 to move rightwards integrally, the switching rod 21 moves rightwards until the second gear 212 can be engaged between the fourth gear 12 and the sixth gear 411, that is, the fourth gear 12, the second gear 212 and the sixth gear 411 are engaged in sequence, then, under the action of wind, the rotating shaft of the fan 1 will rotate to drive the fourth gear 12 to rotate, the fourth gear 12 will drive the second gear 212 to rotate, the second gear 212 will drive the sixth gear 411 to rotate, so that the second power shaft 41 of the water pumping device 4 rotates, and the fan 1 drives the water pumping device 4 to pump water for the operation pool 5; referring to fig. 3, when the liquid level of the working tank 5 is higher than the second critical liquid level line 5b, the rising of the floater 23 can drive the first connecting rod 231 to rise, and further drives the second connecting rod 232 to ascend, so that the switching wheel 22 rotates clockwise, the second gear teeth 221 and the first gear teeth 213 of the switching wheel 22 are engaged to drive the switching rod 21 to move leftwards integrally, the switching rod 21 moves leftwards until the first gear 211 can be engaged between the third gear 11 and the fifth gear 311, that is, the third gear 11, the first gear 211 and the fifth gear 311 are engaged in sequence, then, under the action of wind, the rotating shaft of the fan 1 will rotate to drive the third gear 11 to rotate, the third gear 11 will drive the first gear 211 to rotate, the first gear 211 will drive the fifth gear 311 to rotate, and the first power shaft 31 of the stirring device 3 is rotated, so that the fan 1 drives the stirring device 3 to stir the working pool 5.

The above operation process is only a movement process of the fan control apparatus provided in fig. 1 to 3, and fig. 1 to 3 are operation processes based on the switching wheel 22, the first gear 211 and the second gear 212 arranged in sequence from left to right with the switching wheel 22 disposed above the switching lever 21. The switching wheel 22 may be provided above the switching lever 21 or below the switching lever 21. The switching wheel 22, the first gear 211 and the second gear 212 are arranged in various orders, the switching wheel 22 can be arranged above or below the switching rod 21, various arrangement modes can be combined, the switching wheel 22 is driven to rotate along with the rising or falling of the liquid level through the floater 23, the switching rod 21 is driven to move, the fan 1 can be switched to carry out the water pumping device 4 and the stirring device 3, and detailed working processes of the switching wheel 22, the first gear 211 and the second gear 212 in the arrangement modes are not repeated one by one.

Further, in the present embodiment, referring to fig. 1-3, the operation tank 5 is provided with a vertically disposed limiting frame 51, the float 23 is located inside the limiting frame 51, and the bottom of the limiting frame 51 is communicated with the operation tank 5, so that the float 23 moves up and down along with the liquid level of the operation tank 5. The setting of spacing frame 51 is in order to restrict float 23 and remove along the horizontal direction, and then guarantee that float 23 goes up and down along with the lift of liquid level in vertical direction, thereby restriction head rod 231 can only remove along vertical direction, and head rod 231 that vertical direction removed can raise second connecting rod 232 more easily and then produce and can impel switching wheel 22 pivoted driving force, switching wheel 22's rotation is through the first teeth of a cogwheel 213 and the second teeth of a cogwheel 221 of intermeshing to the driving force of production to switching rod 21 horizontal migration, finally be favorable to making things convenient for the switching of pumping device 4 and agitating unit 3 to go on. Because the liquid in the limit frame 51 and the liquid in the working pool 5 are communicated with each other, namely the liquid level of the limit frame 51 and the liquid level of the working pool 5 can be kept at the same height, the liquid level of the working pool 5 can be detected in real time through the vertical lifting of the floater 23, and the liquid level change of the working pool 5 is fed back to the rotation of the switching wheel 22.

Further, in the present embodiment, referring to fig. 1-3, the bottom of the position-limiting frame 51 is lower than the first threshold level line 5a, and the top of the position-limiting frame 51 is higher than the second threshold level line 5 b. More specifically, the height range of the limiting frame 51 is actually the movable range of the float 23, and the first critical fluid level line 5a and the second critical fluid level line 5b are both the optimal time for switching to perform the mechanical operation, and the movable range of the float 23 must include the area between the first critical fluid level line 5a and the second critical fluid level line 5b, so as to ensure that the switching device 2 can normally operate, and further ensure that the fan 1 can switch to operate according to the change of the fluid level of the working pool 5.

Further, in the present embodiment, referring to fig. 2, the float 23 is spherical, a distance between the bottom of the limiting frame 51 and the first critical liquid level line 5a is equal to a radius of the float 23, and a first through hole (not shown) communicating with the working tank 5 is formed at the bottom of the limiting frame 51. When wind is not stable for a long time and the fan 1 is difficult to rotate, when the liquid level of the working pool 5 is at the first critical liquid level line 5a, the second gear 212 can be meshed between the fourth gear 12 and the sixth gear 411, but because the fan 1 is difficult to rotate, the water pumping device 4 cannot normally operate, the liquid level of the working pool 5 will continue to descend, if the float 23 is not limited by the bottom of the limiting frame 51, the float 23 will continue to descend to drive the switching wheel 22 and further the switching rod 21, the second gear 212 is easy to be disengaged from the fourth gear 12 and the sixth gear 411, and the water pumping device 4 is difficult to start after subsequent wind blows. The shape of the float 23 and the distance between the bottom of the limiting frame 51 and the first critical liquid level line 5a are the most preferable, and it is not excluded that the float 23 has other shapes, and when the distance between the bottom of the limiting frame 51 and the first critical liquid level line 5a is not equal to the radius of the float 23, the situation that the fan 1 normally drives the water pumping device 4 can be realized, which is not described in detail in the present application.

Further, in the present embodiment, referring to fig. 3, the float 23 is spherical, a distance between the top of the limiting frame 51 and the second critical fluid level line 5b is equal to a radius of the float 23, and the top of the limiting frame 51 is provided with a second through hole (not shown) for the first connecting rod 231 to pass through. Since the pumping of the working tank 5 by the pumping device 4 cannot be stopped immediately, it is inevitable that the float 23 is higher than the second critical liquid level line 5b, but the rising of the float 23 will drive the switching wheel 22 and thus the switching rod 21, which will affect the engagement of the first gear 211 between the third gear 11 and the fifth gear 311; in order to ensure that the first gear 211 can always remain engaged between the third gear 11 and the fifth gear 311 when the liquid level of the working bath 5 is higher than the second critical liquid level line 5b, it is also necessary to limit the further rise of the float 23 and ensure that the fan 1 can continuously drive the stirring device 3. The shape of the float 23 and the distance between the top of the limiting frame 51 and the second critical liquid level line 5b are the most preferable, and it is not excluded that the float 23 is in other shapes, and when the distance between the top of the limiting frame 51 and the second critical liquid level line 5b is not equal to the radius of the float 23, the normal driving of the stirring device 3 by the fan can be realized, which is not described in detail in the present application.

Further, in the present embodiment, referring to fig. 1-3, the stirring device 3 further includes a stirring rod 32 and a stirring blade 33, and the stirring blade 33 is rotatably mounted on the stirring rod 32; the first power shaft 31 is provided with a seventh gear 312, the stirring rod 32 is provided with an eighth gear 321, and the seventh gear 312 and the eighth gear 321 are in meshing transmission connection. Because the first power shaft 31 of the stirring device 3 is often difficult to directly participate in the stirring operation of the operation pool 5, the transmission torque and the movement direction can be changed through gear transmission connection, the stirring rods 32 in different directions can be designed for more concrete actual needs to stir the operation pool 5, the drawing of the embodiment only provides the condition that the operation pool 5 is stirred in the vertical direction, and the stirring rods 32 and the stirring blades 33 in other directions are not repeated one by one.

Further, in the present embodiment, referring to fig. 8, the water pumping device 4 further includes a box body 42 and a pump rod 43; a fixed seat is longitudinally arranged in the box body 42, and a supporting seat is fixedly arranged at the front end of the fixed seat; a third through hole which is through is longitudinally arranged in the supporting seat, and the upper side surface of the supporting seat is fixedly provided with a directional rail 44; a matched directional wheel 45 is arranged in the directional rail 44, and a power-assisted shaft is fixedly inserted in the directional wheel 45; the two ends of the power-assisted shaft are hinged with power-assisted arms 46, the middle part of the power-assisted shaft is rotatably provided with a pressing seat, and the bottom end of the pressing seat is fixedly provided with a pump rod 43 penetrating through the third through hole; a pair of lifting gear sets 47 are rotatably arranged in the middle of the fixing seat, and the other end of the power-assisted arm 46 is rotatably connected to the lifting gear sets 47; the lifting gear set 47 is engaged with a pair of power gear sets 48, and the second power shaft 41 is inserted into the power gear sets 48. The directional rail 44 includes a pair of linear slide rails disposed in parallel on the supporting base and a semicircular arc slide rail disposed on the top end of the linear slide rails.

More specifically, when the liquid level of the working pool 5 is lower than the first critical liquid level line 5a, the switching device 2 can sequentially mesh the fourth gear 12, the second gear 212 and the sixth gear 411, and the rotation of the rotating shaft of the fan 1 can drive the second power shaft 41 of the water pumping device 4 to rotate, so as to drive the power gear set 48 to rotate, so as to rotate the meshed lifting gear set 47, because the directional wheel 45 hinged to one end of the assisting arm 46 can only move along the linear slide rail of the directional rail 44, so that the assisting arm 46 rotatably connected to the lifting gear set 47 can drive the directional wheel 45 to reciprocate up and down along the directional rail 44 when the lifting gear set 47 rotates, so as to drive the pump rod 43 on the lower side to pump up and down the water pump piston, and completely convert the wind power into the power for pumping water by the water pump in a mechanical manner, and has a simple structure, Energy saving and environmental protection.

The above operation process is only the movement process of the fan control device provided in fig. 5-7, and fig. 5-7 are the operation process when the switching wheel 22 is disposed above the switching rod 21 and the water pumping device 4 and the stirring device 3 act on different work pools 5, based on the switching wheel 22, the second gear 212 and the first gear 211 being sequentially arranged from left to right. The switching wheel 22 may be provided above the switching lever 21 or below the switching lever 21. The switching wheel 22, the first gear 211 and the second gear 212 are arranged in various orders, the switching wheel 22 can be arranged above or below the switching rod 21, various arrangement modes can be combined, the switching wheel 22 is driven to rotate along with the rising or falling of the liquid level through the floater 23, the switching rod 21 is driven to move, the fan 1 can be switched to carry out the water pumping device 4 and the stirring device 3, and detailed working processes of the switching wheel 22, the first gear 211 and the second gear 212 in the arrangement modes are not repeated one by one.

Further, in the present embodiment, referring to fig. 5-7, the operation tank 5 is provided with a vertically disposed limiting frame 51, the float 23 is located inside the limiting frame 51, and the bottom of the limiting frame 51 is communicated with the operation tank 5, so that the float 23 moves up and down along with the liquid level of the operation tank 5. The setting of spacing frame 51 is in order to restrict float 23 and remove along the horizontal direction, and then guarantee that float 23 goes up and down along with the lift of liquid level in vertical direction, thereby restriction head rod 231 can only remove along vertical direction, and head rod 231 that vertical direction removed can raise second connecting rod 232 more easily and then produce and can impel switching wheel 22 pivoted driving force, switching wheel 22's rotation is through the first teeth of a cogwheel 213 and the second teeth of a cogwheel 221 of intermeshing to the driving force of production to switching rod 21 horizontal migration, finally be favorable to making things convenient for the switching of pumping device 4 and agitating unit 3 to go on. Because the liquid in the limit frame 51 and the liquid in the working pool 5 are communicated with each other, namely the liquid level of the limit frame 51 and the liquid level of the working pool 5 can be kept at the same height, the liquid level of the working pool 5 can be detected in real time through the vertical lifting of the floater 23, and the liquid level change of the working pool 5 is fed back to the rotation of the switching wheel 22.

Further, in the present embodiment, referring to fig. 5-7, the bottom of the position-limiting frame 51 is lower than the first threshold level line 5a, and the top of the position-limiting frame 51 is higher than the second threshold level line 5 b. More specifically, the height range of the limiting frame 51 is actually the movable range of the float 23, and the first critical fluid level line 5a and the second critical fluid level line 5b are both the optimal time for switching to perform the mechanical operation, and the movable range of the float 23 must include the area between the first critical fluid level line 5a and the second critical fluid level line 5b, so as to ensure that the switching device 2 can normally operate, and further ensure that the fan 1 can switch to operate according to the change of the fluid level of the working pool 5.

Further, in the present embodiment, referring to fig. 6, the float 23 is spherical, a distance between the bottom of the limiting frame 51 and the first critical liquid level line 5a is equal to a radius of the float 23, and a first through hole (not shown) communicating with the working tank 5 is formed at the bottom of the limiting frame 51. When wind is not stable for a long time and the fan 1 is difficult to rotate, when the liquid level of the working pool 5 is at the first critical liquid level line 5a, the second gear 212 can be meshed between the fourth gear 12 and the sixth gear 411, but because the fan 1 is difficult to rotate, the water pumping device 4 cannot normally operate, the liquid level of the working pool 5 will continue to descend, if the float 23 is not limited by the bottom of the limiting frame 51, the float 23 will continue to descend to drive the switching wheel 22 and further the switching rod 21, the second gear 212 is easy to be disengaged from the fourth gear 12 and the sixth gear 411, and the water pumping device 4 is difficult to start after subsequent wind blows. The shape of the float 23 and the distance between the bottom of the limiting frame 51 and the first critical liquid level line 5a are the most preferable, and it is not excluded that the float 23 has other shapes, and when the distance between the bottom of the limiting frame 51 and the first critical liquid level line 5a is not equal to the radius of the float 23, the situation that the fan 1 normally drives the water pumping device 4 can be realized, which is not described in detail in the present application.

Further, in the present embodiment, referring to fig. 7, the float 23 is spherical, a distance between the top of the limiting frame 51 and the second critical fluid level line 5b is equal to a radius of the float 23, and the top of the limiting frame 51 is provided with a second through hole (not shown) for the first connecting rod 231 to pass through. Since the pumping of the working tank 5 by the pumping device 4 cannot be stopped immediately, it is inevitable that the float 23 is higher than the second critical liquid level line 5b, but the rising of the float 23 will drive the switching wheel 22 and thus the switching rod 21, which will affect the engagement of the first gear 211 between the third gear 11 and the fifth gear 311; in order to ensure that the first gear 211 can always remain engaged between the third gear 11 and the fifth gear 311 when the liquid level of the working bath 5 is higher than the second critical liquid level line 5b, it is also necessary to limit the further rise of the float 23 and ensure that the fan 1 can continuously drive the stirring device 3. The shape of the float 23 and the distance between the top of the limiting frame 51 and the second critical liquid level line 5b are the most preferable, and it is not excluded that the float 23 is in other shapes, and when the distance between the top of the limiting frame 51 and the second critical liquid level line 5b is not equal to the radius of the float 23, the normal driving of the stirring device 3 by the fan can be realized, which is not described in detail in the present application.

Further, in the present embodiment, referring to fig. 5-7, the stirring device 3 further includes a stirring rod 32 and a stirring blade 33, and the stirring blade 33 is rotatably mounted on the stirring rod 32; the first power shaft 31 is provided with a seventh gear 312, the stirring rod 32 is provided with an eighth gear 321, and the seventh gear 312 and the eighth gear 321 are in meshing transmission connection. Because the first power shaft 31 of the stirring device 3 is often difficult to directly participate in the stirring operation of the operation pool 5, the transmission torque and the movement direction can be changed through gear transmission connection, the stirring rods 32 in different directions can be designed for more concrete actual needs to stir the operation pool 5, the drawing of the embodiment only provides the condition that the operation pool 5 is stirred in the vertical direction, and the stirring rods 32 and the stirring blades 33 in other directions are not repeated one by one.
