Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration and cooling, in particular to a cold curtain type cooling device. Background Art

[0002] The cold curtain type cooling device mainly has a thin water film on the surface of the corrugated fiber. When the outdoor dry and hot air is sucked through the paper by a fan, the water on the water film will absorb the heat of the air and then evaporate into steam, so that the cool and moist air after treatment enters the room.

[0003] The traditional cold curtain type cooling device generally has a body, with a water tank arranged inside, a water pump arranged in the water tank, a cold curtain arranged inside, and a fan arranged at the front end of the cold curtain. The water pump pumps water to the water spraying ports at the upper end inside the body to spray and wet the cold curtain. The dry heat indoors is sucked into the cold curtain by the fan. The hot air evaporates the water and thus consumes heat and becomes cool, and the cooled air is then conveyed out by the fan.

[0004] This type of cold curtain type cooling device has the following disadvantages: the blown-out wind is relatively dispersed, the air supply distance of the fan is relatively short, and the application range is relatively small. Therefore, we propose a cold curtain type cooling device. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a cold curtain type cooling device, which makes the wind force of the fan more concentrated by the extension of the rotating guide cylinder and the moving guide cylinder, thereby increasing the air supply range, and cooperating with the adjustment of the left and right air supply angles to increase the cooling range, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a cold curtain type cooling device, including a body and a cooling mechanism;

The top wall of the cavity of the body is fixedly connected with a water outlet pipe through evenly distributed connecting pins. The lower end of the water outlet pipe is provided with evenly distributed water outlet ports. The water outlet of the water pump is connected to the water inlet of the water outlet pipe through a pipeline. A control switch group is arranged in the middle of the front side of the body;

[0008] The cooling mechanism: it is arranged in the installation seat;

[0009] Among them: the input end of the control switch group is electrically connected to an external power supply, the input end of the water pump is electrically connected to the output end of the control switch group. The wind force of the fan is made more concentrated by the extension of the rotating guide cylinder and the moving guide cylinder, thereby increasing the air supply range, and cooperating with the adjustment of the left and right air supply angles to increase the cooling range.

[0010] Furthermore, the cooling mechanism includes a spiral groove, a rotating guide cylinder, and a moving guide cylinder. The rotating guide cylinder is rotatably connected to a rotating hole in the middle of the mounting base. A spiral groove is provided inside the rotating guide cylinder. The moving guide cylinder is slidably connected to the rotating guide cylinder through a sliding column. A sliding groove is provided at the front end of the mounting base. A sliding rod is fixedly connected to the rear end of the moving guide cylinder, and the sliding rod is slidably connected to the sliding groove, facilitating the extension of the guide cylinder and limiting the extension of the guide cylinder.

[0011] Furthermore, the cooling mechanism further includes an annular gear, a second motor, and a gear. An annular gear is provided at the rear end of the rotating guide cylinder. A mounting block is provided at the upper end of the mounting base. A second motor is fixedly connected to the rear end of the mounting block. A gear is provided at the rear end of the output shaft of the second motor. The gear is meshed with the annular gear. The input end of the second motor is electrically connected to the output end of the control switch group, providing power for the extension of the guide cylinder.

[0012] Furthermore, the cooling mechanism further includes guide vanes and a blower. Uniformly distributed rotating shafts are provided on both the left and right sides at the front end of the moving guide cylinder. Guide vanes are rotatably connected between the rotating shafts. A blower is provided at the rear end of the rotating guide cylinder. The guide vanes and the blower are corresponding in the front and rear positions. The input end of the blower is electrically connected to the output end of the control switch group, providing wind power.

[0013] Furthermore, a first motor is provided in the middle of the left inner wall of the cavity of the machine body. A worm is provided at the right end of the output shaft of the first motor. The right end of the worm is rotatably connected to the right inner wall of the machine body. A semi-worm gear is sleeved outside the rotating shaft at the lower end of the mounting base. The semi-worm gear is meshed with the worm. The input end of the first motor is electrically connected to the output end of the control switch group, adjusting the angle of cooling.

[0014] Furthermore, uniformly distributed water curtains are provided in the cavity of the machine body.

The ventilation openings and the water curtains are correspondingly arranged, cooling the hot air drawn into the machine body.

[0015] Furthermore, a rear door is hinged to the rear side of the machine body through a hinge, facilitating the addition of water to the water tank.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: This cold curtain type cooling device has the following advantages:

[0017] If it is necessary to swing the air outlet left and right, the first motor needs to be started through the control switch group. The rotation of the first motor drives the worm to rotate, and the worm drives the semi-worm gear to rotate along the same central axis as the mounting seat, thereby driving the mounting seat to rotate synchronously to achieve the adjustment of left and right air supply. If it is necessary to adjust the air supply distance, the second motor needs to be started through the control switch group. The rotation of the output shaft of the second motor drives the gear to rotate, and the gear drives the annular gear to drive the rotating guide cylinder to rotate in the rotating hole in the middle of the mounting seat. The rotation of the rotating guide cylinder changes the angle of the spiral groove inside the rotating guide cylinder, thereby squeezing the sliding column, causing the moving guide cylinder to slide and guide under the action of the extrusion force. Since the central axes of the moving guide cylinder 203, the spiral groove 201, and the rotating guide cylinder 202 coincide, the sliding column is forced to drive the moving guide cylinder forward. At this time, the sliding rod at the rear end of the moving guide cylinder slides forward in the sliding groove in the mounting seat, thereby extending and lengthening the guide cylinder in front of the fan while limiting the rotating guide cylinder to a certain extent, restricting the extension length of the wind guiding cylinder, preventing wind loss due to the too long extension cylinder, and cooperating with the left and right air supply. In this way, the cooling range becomes larger. By the extension of the rotating guide cylinder and the moving guide cylinder, the wind force of the fan is more concentrated, thereby increasing the air supply distance, and cooperating with the adjustment of the left and right air supply angles to increase the cooling range.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 3 , this embodiment provides a technical solution: a cold curtain type cooling device, including a machine body 1 and a cooling mechanism 2;

[0024] Machine body 1: An installation opening 14 is provided at the upper end of its front side. Rotating shafts are rotatably connected to the middle parts of the upper and lower side walls of the installation opening 14. An installation seat 13 is fixedly connected between the rotating shafts. A water tank 11 is provided at the bottom of the cavity of the machine body 1. A water pump 6 is arranged on the right side of the water tank 11. The top wall of the cavity of the machine body 1 is fixedly connected with a water outlet pipe 5 through evenly distributed connecting pins. The lower end of the water outlet pipe 5 is provided with evenly distributed water outlets. The water outlet of the water pump 6 is connected to the water inlet of the water outlet pipe 5 through a pipeline. A control switch group 3 is arranged in the middle of the front side of the machine body 1. A first motor 7 is arranged in the middle of the left inner wall of the cavity of the machine body 1. A worm 8 is arranged at the right end of the output shaft of the first motor 7. The right end of the worm 8 is rotatably connected to the right inner wall of the machine body 1. A semi-worm gear 9 is sleeved outside the rotating shaft located at the lower end of the installation seat 13. The semi-worm gear 9 is meshed and connected with the worm 8. The input end of the first motor 7 is electrically connected to the output end of the control switch group 3. Uniformly distributed water curtains 4 are arranged in the cavity of the machine body 1. Uniformly distributed ventilation openings 10 are provided on both the left and right side walls of the machine body 1. The ventilation openings 10 and the water curtains 4 are arranged correspondingly. A rear door 12 is hinged to the rear side of the machine body 1 through a hinge. If left and right swing ventilation is required, the first motor 7 needs to be started through the control switch group 3. The first motor 7 rotates to drive the worm 8 to rotate. The worm 8 drives the semi-worm gear 9 to drive the installation seat 13 to rotate, so as to drive the installation seat 13 to rotate synchronously to realize the adjustment of left and right ventilation. The universal wheels at the lower end of the machine body 1 move the machine body 1 to a preset area, then open the rear door 12 at the rear end of the machine body 1, add an appropriate amount of water to the water tank 11, and then turn on the water pump 6 through the control switch group 3. The water pump 6 is turned on to transport the water in the water tank 11 to the water outlet pipe 5, and the water is sprayed out through the water outlets of the water outlet pipe 5 to wet the water curtains 4;

[0025] Cooling mechanism 2: It is arranged inside the mounting base 13. The cooling mechanism 2 includes a spiral groove 201, a rotating guide cylinder 202, and a moving guide cylinder 203. The rotating guide cylinder 202 is rotatably connected to the rotating hole in the middle of the mounting base 13. A spiral groove 201 is opened inside the rotating guide cylinder 202. The moving guide cylinder 203 is slidably connected to the inside of the rotating guide cylinder 202 through a sliding column. A sliding groove 209 is opened at the front end of the mounting base 13. A sliding rod 210 is fixedly connected to the rear end of the moving guide cylinder 203. The sliding rod 210 is slidably connected to the sliding groove 209. The cooling mechanism 2 further includes an annular gear 205, a second motor 206, and a gear 207. An annular gear 205 is arranged at the rear end of the rotating guide cylinder 202. A mounting block is arranged at the upper end of the mounting base 13. A second motor 206 is fixedly connected to the rear end of the mounting block. A gear 207 is arranged at the rear end of the output shaft of the second motor 206. The gear 207 is meshed with the annular gear 205. The input end of the second motor 206 is electrically connected to the output end of the control switch group 3. The cooling mechanism 2 further includes a guide vane 204 and a blower 208. Uniformly distributed rotating shafts are arranged on both the left and right sides at the front end of the moving guide cylinder 203. Guide vanes 204 are rotatably connected between the rotating shafts. A blower 208 is arranged at the rear end of the rotating guide cylinder 202. The guide vane 204 and the blower 208 are corresponding in the front and rear positions. The input end of the blower 208 is electrically connected to the output end of the control switch group 3. If it is necessary to adjust the air supply distance, it is necessary to start the second motor 206 through the control switch group 3. The output shaft of the second motor 206 rotates to drive the gear 207 to rotate. The gear 207 drives the annular gear 205 to drive the rotating guide cylinder 202 to rotate in the rotating hole in the middle of the mounting base 13. The rotation of the rotating guide cylinder 202 changes the angle of the spiral groove 201 located inside the rotating guide cylinder 202, thereby squeezing the sliding column, causing the moving guide cylinder 203 to perform sliding guidance under the action of the extrusion force. Since the central axes of the moving guide cylinder 203, the spiral groove 201, and the rotating guide cylinder 202 coincide, the sliding column is forced to drive the moving guide cylinder 203 to move forward. At this time, the sliding rod 210 at the rear end of the moving guide cylinder 203 slides forward in the sliding groove 209 inside the mounting base 13, thereby extending the guide cylinder in front of the blower 208 while performing a certain limit on the rotating guide cylinder 202, restricting the extended length of the wind guiding cylinder, preventing wind loss due to the overly long extension cylinder, and then cooperating with the left and right air supply, so that the cooling range becomes larger. By the extension of the rotating guide cylinder and the moving guide cylinder, the wind force of the blower is more concentrated, thereby increasing the air supply distance, and then cooperating with the adjustment of the left and right air supply angles to increase the cooling range;

[0026] Among them: The input end of the control switch group 3 is electrically connected to an external power supply, and the input end of the water pump 6 is electrically connected to the output end of the control switch group 3.

[0027] The working principle of a cold curtain cooling device provided by the utility model is as follows: if a place needs to use the cold curtain cooling device for cooling, the staff responsible for cooling needs to first move the body 1 to a preset area through the universal wheels at the lower end of the body 1, then open the rear door 12 at the rear end of the body 1, add a proper amount of water into the water tank 11, and then turn on the water pump 6 through the control switch group 3. The water pump 6 is turned on to transport the water from the water tank 11 to the water outlet pipe 5, and spray it out through the water outlet of the water outlet pipe 5 to wet the water curtain 4, and then turn on the fan 208 through the control switch group 3 The fan 208 draws the external hot air into the cavity of the body 1 through the vent 10. In this process, the hot air passes through the wet water curtain 4 to evaporate the water on the water curtain, thereby consuming the heat in the air, and then is drawn out by the fan 208 to the place where the temperature needs to be lowered. If the height of the air outlet needs to be adjusted, it is only necessary to manually adjust the angle of the guide vane 204 by turning the guide vane 204. If the air needs to be shaken left and right, it is necessary to start the first motor 7 through the control switch group 3. The first motor 7 rotates to drive the worm 8 to rotate, and the worm 8 drives the semi-worm gear 9 to drive the mounting seat 13 to rotate. The second motor 206 is started by the control switch group 3, and the output shaft of the second motor 206 rotates to drive the gear 207 to rotate. The gear 207 drives the ring gear 205 to drive the rotating guide cylinder 202 to rotate in the rotating hole in the middle of the mounting seat 13. The rotating guide cylinder 202 rotates to change the angle of the spiral groove 201 inside the rotating guide cylinder 202, thereby squeezing the sliding column to cause the mobile guide cylinder 203 to slide and guide under the action of the squeezing force. The central axes of the movable guide cylinder 203, the spiral groove 201 and the rotating guide cylinder 202 coincide with each other, thus forcing the sliding column to drive the movable guide cylinder 203 to move forward, thereby driving the sliding rod 210 at the rear end of the movable guide cylinder 203 to slide forward in the sliding groove 209 in the mounting seat 13, thereby extending and extending the guide cylinder in front of the fan 208 while limiting the rotating guide cylinder 202 to a certain extent, limiting the extended length of the wind guide cylinder, preventing wind loss due to excessive extension of the cylinder, and combining with the left and right air supply, the cooling range is expanded.

[0028] It is worth noting that the second motor 206 disclosed in the above embodiment can be selected as the first motor 7 and the 110BYGH1.8 two-phase stepper motor, the fan 208 can be selected as XWY-FJ-43KA, and the water pump 6 is recommended to use the MK series. The control switch group 3 is provided with buttons corresponding to the second motor 206, the first motor 7, the fan 208 and the water pump 6 and controlling the switch of the controller.

[0029] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
