[0019] A method for using a ventilation and cooling system for an industrial workshop comprises the following steps:

[0020] S1. With the start-up of the device, the motor drives the shaft to rotate the induced draft duct, and the induced draft duct drives the blades inside it to rotate synchronously. Since the blades are turbine blades, the external airflow can be sucked in, and the airflow passes through the induced draft duct and flows into the interior of the rotating bin;

[0021] S2. With the rotation of the induced draft duct, the induced draft duct drives the rotating bin to rotate synchronously, so that the airflow entering the rotating bin will continuously contact the water curtain plate in the unfolded state, disturbing the airflow and cooling it quickly. At the same time, when the airflow merges into the rotating bin, it will be temporarily retained to increase the cooling effect of the airflow. With the continuous entry of external airflow, the cooled air is discharged through the output pipe and sent into the factory for cooling;

[0022] S3. As the duct rotates, the duct drives the transmission plate to rotate slowly through the small gears meshing on both sides. When the lever on the transmission plate passes through the raised block, it can push the dial to rotate until the end of the lever passes through the release groove. The lever is reset by the tension spring, so that the lever is away from the dial, and the dial is reset by the torsion spring. At this time, since a one-way shaft is used between the dial and the rotating ring, and the rotating ring is fitted with the rotating bin through the rubber layer on the outer wall, there is no interference between the rotating ring and the dial when it rotates. When the dial is turned, When the gears move to the opposite direction and then reset, interference occurs due to the different rotation directions, causing rotation between the rotating ring and the rotating chamber. Several gear grooves on the rotating ring leave the driving gears of the current group and rotate toward another group of driving gears. At this time, due to the separation of the gear grooves from the current group of driving gears, the driving gears of the current group begin to reset through the torsion spring, causing the upper water curtain plate to rotate inward for recovery. At the same time, the next group of driving gears meshes with several gear grooves, causing the driving gears to rotate and drive the water curtain plate to rotate outward to realize the opening operation, and the two groups of water curtain plates are switched.

[0023] S4. At the same time, when the toggle plate is pushed to rotate, the power plate on one side of the toggle plate drives the guide plate to move synchronously. Due to the setting of the inclined slot, along with the movement of the guide plate, the positioning rod continuously moves upward under the action of the inclined slot. At this time, the end of the positioning rod moves vertically up and down in the arc groove on the rotating column. Due to the setting of the arc structure, the positioning rod can drive the rotating column to rotate 180 degrees when it moves vertically upward. At this time, the rotation of the rotating column will pull the spring telescopic rod to move forward through the hinge rod. At this time, the bottom end of the spring telescopic rod contacts the outer wall of the second water tank and contracts itself until the spring telescopic rod passes over the outer wall of the second water tank. The spring telescopic rod is unfolded to align the water outlet with the second water tank;

[0024] S5. At the same time, when the positioning rod moves upward, the positioning rod rises and pushes the push rod to move upward synchronously. The top of the push rod contacts the inclined plate, thereby pushing the water control tank to move outward. The end of the water control tank is separated from the piston, so that the water control tank and the two mounting sleeves are connected. At this time, the external water source can be pumped into it and enter the corresponding water curtain plate through the second water tank;

[0025] Finally, when the transmission disc is reset, the positioning rod can be driven to reset, thereby resetting the water control tank, causing the water supply to stop and completing all operations.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the present invention, by setting two sets of switchable water curtain plates, the airflow is disturbed when the water curtain plates rotate, so that the airflow is fully in contact with the water curtain plates, and the temperature of the inhaled air is quickly reduced. The switchable setting allows the water curtain plates to be used all the time. If there is a lack of water, another set of water curtain plates will be replaced. The cooling of the airflow can be maintained at all times, which facilitates the use of the device.

[0028] In the present invention, the turbine structure of the blades and the uneven structure on the blades can slow down the inhaled air before entering the rotating bin. The low-speed airflow has a long retention time and is fully cooled, making the device easier to use.

[0029] In the present invention, by setting up the control mechanism, water is supplied to the retracted water curtain plate in advance before switching the water curtain plate, so that the water curtain plate is always kept in a wet state during switching. BRIEF DESCRIPTION OF THE DRAWINGS

When the toggle plate 565 moves to the left and then resets, interference occurs due to the different rotation directions, causing rotation between the rotating ring 52 and the rotating bin 51.

Through the arrangement of the first water tank 58 and the second water tank 59, the two groups of water curtain plates 55 can be supplied with water separately, which is convenient for coordinating the switching operation of the water curtain plates 55.

[0056] In this embodiment, Figure 1 , Figure 4 , Fig.11 , Fig.12 and Fig.13 As shown, the control mechanism 6 includes a power plate 61, the side wall of the power plate 61 is fixedly connected to the outer wall of the dial 565, the power plate 61 is arranged in a U-shaped structure, the outer wall of the power plate 61 is arranged to slide horizontally with the inner wall of the housing 1, the top of the power plate 61 is fixedly connected to a guide plate 62, the inner wall of the guide plate 62 is provided with an oblique groove 63 inclined upward, and a positioning rod 64 is slidably connected in the oblique groove 63;

[0057] An installation bin 65 is fixedly connected to the inner wall of the housing 1, a return spring is fixedly connected to the top of the installation bin 65, and a sliding block 66 is fixedly connected to the bottom end of the return spring. The outer wall of the sliding block 66 is vertically slidably arranged with the inner wall of the installation bin 65, a hinged rod 67 is hinged at the bottom end of the sliding block 66, a spring telescopic rod 68 is hinged at the bottom end of the hinged rod 67, a pulling rod 69 is connected to the hinged end of the hinged rod 67 and the spring telescopic rod 68 through a universal shaft, and a rotating column 610 is rotatably connected to the front end of the pulling rod 69, and two symmetrically arranged arc grooves 611 are provided on the outer wall of the rotating column 610, and the two arc grooves 611 are connected head to tail through a vertical groove 612, and the groove depth of the two arc grooves 611 is gradually increased from top to bottom, and when the toggle plate 565 is pushed to rotate When the lever 564 is in motion, the power plate 61 on one side of the toggle plate 565 drives the guide plate 62 to move synchronously. Due to the setting of the inclined groove 63, along with the movement of the guide plate 62, the positioning rod 64 continuously moves upward under the action of the inclined groove 63. At this time, the end of the positioning rod 64 moves vertically up and down in the arc groove 611 on the rotating column 610. Due to the setting of the arc structure, the rotating column 610 can be driven to rotate 180 degrees when the positioning moves vertically upward. At this time, the rotation of the rotating column 610 will pull the spring telescopic rod 68 to move forward through the hinge rod 67. At this time, the bottom end of the spring telescopic rod 68 contacts the outer wall of the second water tank 59 and contracts itself until the spring telescopic rod 68 passes over the outer wall of the second water tank 59. The spring telescopic rod 68 unfolds and aligns the water outlet with the second water tank 59.

A piston 615 is fitted in the inner wall of the water control tank 613, and the rear end of the piston 615 is fixedly connected to a connecting rod 616, and the connecting rod 616 is fixedly connected to the inner wall of the installation sleeve 614 on the right side of the water control tank 613;

[0059] The bottom end of the water control tank 613 is fixedly connected with an inclined plate 617, and a push rod 618 with an L-shaped structure is attached to the side wall of the inclined plate 617;

At the same time, when the positioning rod 64 moves up, the positioning rod 64 rises and pushes the push rod 618 to move up synchronously. The top of the push rod 618 contacts the inclined plate 617, thereby pushing the water control tank 613 to move outward. The end of the water control tank 613 is separated from the piston 615, so that the water control tank 613 and the two installation sleeves 614 are connected. At this time, external water can be pumped into it and enter the corresponding water curtain plate 55 through the second water tank 59.

[0061] In this embodiment, Figures 1 to 5 As shown, a method for using a ventilation and cooling system for an industrial workshop comprises the following steps:

[0062] S1. With the start of the device, the motor drives the shaft 4 to drive the air duct 2 to rotate, and the air duct 2 drives the blades 3 inside it to rotate synchronously. Since the blades 3 are turbine blades 3, the external airflow can be sucked in, and the airflow passes through the air duct 2 and flows into the interior of the rotating chamber 51;

[0063] S2. With the rotation of the induced draft duct 2, the induced draft duct 2 drives the rotating bin 51 to rotate synchronously, so that the airflow entering the rotating bin 51 will continuously contact the water curtain plate 55 in the deployed state, disturbing the airflow while cooling it quickly. At the same time, when the airflow merges into the rotating bin 51, it will be temporarily retained to increase the cooling effect of the airflow. With the continuous inflow of external airflow, the cooled air is discharged through the output pipe, and the cold air is sent into the factory for cooling;

[0064] S3. With the rotation of the induced draft duct 2, the induced draft duct 2 drives the transmission plate 561 to rotate slowly through the small gears 562 meshing on both sides. When the lever 563 on the transmission plate 561 passes through the protruding block 566, it can push the toggle plate 565 to rotate. Until the end of the lever 563 passes through the release groove 564, the lever 563 is reset by the tension spring, so that the lever 563 is away from the toggle plate 565, and the toggle plate 565 is reset by the torsion spring. At this time, since a one-way shaft is used between the toggle plate 565 and the rotating ring 52, and the rotating ring 52 is fitted with the rotating chamber 51 through the rubber layer on the outer wall, when the rotating ring 52 rotates itself, no interference is generated between the toggle plate 565 When the dial 565 moves to the front and then resets, interference occurs due to the different rotation directions, causing rotation between the rotating ring 52 and the rotating chamber 51. The gear grooves 53 on the rotating ring 52 leave the driving gear 54 of the current group and rotate toward the other driving gear 54. At this time, due to the separation of the gear grooves 53 from the current driving gear 54, the current driving gear 54 begins to reset through the torsion spring, causing the upper water curtain plate 55 to rotate inward for recovery. At the same time, the next driving gear 54 is meshed with the gear grooves 53, causing the driving gear 54 to rotate and drive the water curtain plate 55 to rotate outward to realize the opening operation, and the two groups of water curtain plates 55 are switched.

[0065] S4. At the same time, when the toggle plate 565 is pushed to rotate, the power plate 61 on one side of the toggle plate 565 drives the guide plate 62 to move synchronously. Due to the setting of the inclined groove 63, along with the movement of the guide plate 62, the positioning rod 64 continuously moves upward under the action of the inclined groove 63. At this time, the end of the positioning rod 64 moves vertically up and down in the arc groove 611 on the rotating column 610. Due to the setting of the arc structure, the rotating column 610 can be driven to rotate 180 degrees when the positioning is vertically moved upward. At this time, the rotation of the rotating column 610 will pull the spring telescopic rod 68 to move forward through the hinge rod 67. At this time, the bottom end of the spring telescopic rod 68 contacts the outer wall of the second water tank 59 and contracts itself until the spring telescopic rod 68 passes over the outer wall of the second water tank 59. The spring telescopic rod 68 is unfolded to align the water outlet with the second water tank 59;

[0066] S5. At the same time, when the positioning rod 64 moves upward, the positioning rod 64 moves upward and pushes the push rod 618 to move upward synchronously. The top of the push rod 618 contacts the inclined plate 617, thereby pushing the water control tank 613 to move outward. The end of the water control tank 613 is separated from the piston 615, so that the water control tank 613 and the two mounting sleeves 614 are connected. At this time, the external water source can be pumped into it and enter the corresponding water curtain plate 55 through the second water tank 59;

[0067] Finally, when the transmission disc 561 is reset, the positioning rod 64 can be driven to reset, thereby resetting the water control tank 613, so that the water supply is stopped and all operations are completed.

[0068] The above shows and describes the basic principles, main features and advantages of the present invention.

6. The method for using the ventilation and cooling system for industrial workshops according to claim 5 is characterized in that: The steps include: S1. With the start-up of the device, the motor drives the shaft (4) to drive the induced draft pipe (2) to rotate, and the induced draft pipe (2) drives the blades (3) inside the induced draft pipe to rotate synchronously. Since the blades (3) are turbine blades (3), external airflow can be sucked in, and the airflow passes through the induced draft pipe (2) and flows into the interior of the rotating chamber (51); S2, with the rotation of the induced draft duct (2), the induced draft duct (2) drives the rotating bin (51) to rotate synchronously, so that the airflow entering the rotating bin (51) will continuously contact the water curtain plate (55) in the deployed state, disturbing the airflow while rapidly cooling it. At the same time, when the airflow merges into the rotating bin (51), it will be temporarily retained to increase the cooling effect of the airflow. With the continuous inflow of external airflow, the cooled air is discharged through the output pipe, and the cold air is sent into the factory for cooling; S3. As the induced air duct (2) rotates, the induced air duct (2) drives the transmission plate (561) to rotate slowly through the small gears (562) meshed on both sides. When the lever (563) on the transmission plate (561) passes through the protruding block (566), it can push the toggle plate (565) to rotate until the end of the lever (563) passes through the release groove (564). The lever (563) is reset by the tension spring, so that the lever (563) is away from the toggle plate (565). The toggle plate (565) is reset by the torsion spring. At this time, since a one-way shaft is used between the toggle plate (565) and the rotating ring (52), and the rotating ring (52) is fitted with the rotating chamber (51) through the rubber layer on the outer wall, when the rotating ring (52) rotates itself, it will not come into contact with the toggle plate (565). When the dial (565) moves to the front and then resets, interference occurs due to the different rotation directions, causing rotation between the rotating ring (52) and the rotating chamber (51), and the plurality of gear grooves (53) on the rotating ring (52) separate from the driving gear (54) of the current group and rotate toward the other driving gear (54). At this time, due to the separation of the gear grooves (53) from the driving gear (54) of the current group, the driving gear (54) of the current group begins to reset through the torsion spring, causing the upper water curtain plate (55) to rotate inward for recovery. At the same time, the next group of driving gears (54) meshes with the plurality of gear grooves (53), causing the driving gear (54) to rotate and drive the water curtain plate (55) to rotate outward to achieve an opening operation, thereby switching between the two groups of water curtain plates (55). S4. At the same time, when the toggle plate (565) is pushed to rotate, the power plate (61) on one side of the toggle plate (565) drives the guide plate (62) to move synchronously. Due to the setting of the inclined groove (63), along with the movement of the guide plate (62), the positioning rod (64) continuously moves upward under the action of the inclined groove (63). At this time, the end of the positioning rod (64) moves vertically up and down in the arc groove (611) on the rotating column (610). Due to the setting of the arc structure, the positioning rod (64) can drive the rotating column (610) to rotate 180 degrees when it moves vertically upward. At this time, the rotation of the rotating column (610) pulls the spring telescopic rod (68) to move forward through the hinge rod (67). At this time, the bottom end of the spring telescopic rod (68) contacts the outer wall of the second water tank (59) and contracts until the spring telescopic rod (68) passes over the outer wall of the second water tank (59). The spring telescopic rod (68) is unfolded to align the water outlet with the second water tank (59); S5. At the same time, when the positioning rod (64) moves upward, the positioning rod (64) rises and pushes the push rod (618) to move upward synchronously. The top of the push rod (618) contacts the inclined plate (617), thereby pushing the water control tank (613) to move outward. The end of the water control tank (613) is separated from the piston (615), so that the water control tank (613) and the two mounting sleeves (614) are connected. At this time, the external water source can be pumped into it and enter the corresponding water curtain plate (55) through the second water tank (59); Finally, when the transmission disc (561) is reset, the positioning rod (64) can be driven to reset, thereby causing the water control tank (613) to reset, causing the water supply to stop, and completing all operations.
