Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, and in particular to a cooling tower with a packing protection device. Background Technology

[0002] As a key piece of equipment in industrial circulating water systems, cooling towers function primarily to reduce water temperature through heat and moisture exchange between water and air. Airflow is a crucial factor affecting cooling efficiency: insufficient airflow leads to inadequate heat exchange and increased energy consumption; excessive airflow, on the other hand, can cause turbulent airflow within the tower, water droplet dispersion, and even equipment corrosion and environmental pollution. However, typhoons are unavoidable natural disasters, and their destructive power is terrifying. Cooling towers installed outdoors or on rooftops are particularly vulnerable and become one of the main targets of typhoon damage. Crossflow cooling towers have exposed packing material, which can be damaged by strong winds. Since the packing material is fixed during installation, it is impossible to allocate manpower and resources in time to remove and protect it before a typhoon arrives. Summary of the Invention

[0006] Furthermore, a limiting block is fixedly connected to the top of the movable block, the movable block is engaged with the first support plate through the limiting block, and the movable block is engaged with the second support plate through the limiting block.

[0007] Furthermore, a movable frame is fixedly connected to the top of the first support plate, a spray pipe is fixedly connected to the inner side wall of the movable frame, and a sprayer is fixedly connected to the bottom of the spray pipe.

[0008] Furthermore, the inner wall of the fixed base is provided with a sliding groove, and the outer wall of the movable block is fixedly connected with a slider, the outer wall of the slider being fitted with the inner wall of the sliding groove.

[0009] Furthermore, a return spring is fixedly connected to the bottom of the movable block, and the end of the return spring away from the movable block is fixedly connected to the inner bottom of the fixed base.

At the same time, the structure of the transmission box and support rod enhances the rigidity of the exhaust system, reduces vibration and noise, and improves the reliability of the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the present invention provides a technical solution: a cooling tower with a packing protection device, including a cooling tower body 1, and an air inlet mechanism 2 is provided on the inner side wall of the cooling tower body 1; The cooling tower body 1 is equipped with an adjustment structure 3 inside; An exhaust structure 4 is provided on the top of the main body 1 of the cooling tower; The air intake mechanism 2 includes a baffle plate 201 rotatably connected to the outer wall of the cooling tower body 1. An adjusting plate 202 is fixedly connected to the outer wall of the baffle plate 201. A drive motor 203 is fixedly connected to the inner wall of the cooling tower body 1. A fixing frame 204 is fixedly connected to the inner wall of the cooling tower body 1. A limiting groove 207 is formed through the outer wall of the fixing frame 204. A moving rod 208 is slidably connected to the fixing frame 204 through the limiting groove 207. A half gear 210 is rotatably connected to the inner wall of the cooling tower body 1. A rotating rod 211 is fixedly connected to the outer wall of the half gear 210. A connecting rod 209 is rotatably connected to the end of the rotating rod 211 away from the half gear 210. The connecting rod 209 is located away from the rotating rod 211. One end of the moving rod 208 is rotatably connected to the outer wall of the moving rod 208. A rack 212 is slidably connected to the inner wall of the cooling tower body 1. The side of the rack 212 near the half gear 210 meshes with the outer wall of the half gear 210. A locking pin 213 is fixedly connected to the side of the rack 212 away from the half gear 210. A slot 214 is opened through the outer wall of the adjusting plate 202. The rack 212 is slidably connected to the adjusting plate 202 through the locking pin 213. A rotating column 205 is fixedly connected to the output end of the drive motor 203. The rotating column 205 is rotatably connected to the fixed frame 204. A drive groove 206 is opened on the outer wall of the rotating column 205. The end of the moving rod 208 away from the connecting rod 209 is located inside the drive groove 206. During actual operation, the anemometer continuously monitors the external wind force and transmits real-time data to the control system. When the wind force is within the normal range, the drive motor 203 is in standby mode, the rotating column 205 is stationary, and the moving rod 208 is located at the upper part of the drive groove 206. At this time, the baffle 201 remains open under its own weight and the reset mechanism, the air inlet is fully open, and the cooling tower operates normally. When the anemometer detects excessive wind force, it sends a start signal to the drive motor 203. After receiving the signal, the drive motor 203 drives the rotating column 205 to rotate. Since one end of the moving rod 208 is embedded in the drive groove 206 of the rotating column 205, the rotation of the rotating column 205 pushes the moving rod 208 downward along the limiting groove 207 on the fixed frame 204 through the spiral contour of the drive groove 206. The downward stroke of the moving rod 208 is controlled by the pitch and rotation angle of the drive groove 206 to ensure accurate response to wind force changes. The baffle 201 and the adjusting plate 202 are made of aluminum alloy with an anti-rust coating. The drive motor 203 is a stepper motor, and its speed and direction are adjusted by the control system based on the anemometer signal. The fixing frame 204 is fixed to the inner wall of the cooling tower body 1 by welding. The limiting groove 207 is a rectangular groove to ensure that the moving rod 208 can only slide in the vertical direction. The drive groove 206 on the rotating column 205 is a spiral groove with a precisely calculated profile to optimize the lifting trajectory of the moving rod 208. When the moving rod 208 descends, it drives the connecting rod 209, which is rotatably connected to it, to move downward. The other end of the connecting rod 209 is rotatably connected to the rotating rod 211, which is fixed to the half gear 210. Therefore, the downward pressure of the connecting rod 209 is transmitted to the rotating rod 211, causing the half gear 210 to rotate. The half gear 210 meshes with the rack 212, and the rotation of the half gear 210 drives the rack 212 to move upward. The locking pin 213 on the rack 212 is embedded in the slot 214 of the adjusting plate 202. The upward movement of the rack 212 drives the adjusting plate 202 to rotate around its rotational connection point with the cooling tower body 1 via the locking pin 213. The adjusting plate 202 is fixedly connected to the baffle plate 201, so the baffle plate 201 rotates accordingly, gradually closing the air inlet, reducing the air intake, effectively preventing strong winds from disrupting the airflow balance inside the tower, and ensuring smooth transmission. An anemometer is installed on the side wall of the rack 212 and connected to the drive motor 203 via a cable to transmit wind force data in real time. When the wind weakens, the anemometer sends a signal again, the drive motor 203 reverses, and the rotating column 205 rotates. The moving rod 208 rises under the guidance of the drive groove 206, and the connecting rod 209 rises accordingly, relieving the pressure on the rotating rod 211. The half gear 210 rotates under the gravity of the rack 212 or the action of the auxiliary reset mechanism, driving the rack 212 to move downward, and the wind deflector 201 gradually resets to the open state.

[0018] like Figure 1 , Figure 2As shown, a wind speed meter is installed on the side of the rack 212 near the pin 213 to monitor the wind force in the external environment.

[0019] like Figure 2 , Figure 3 As shown, the adjustment structure 3 includes a fixed base 301 fixedly connected to the inner wall of the cooling tower body 1. A support block 302 is fixedly connected to one end of the moving rod 208 away from the limiting groove 207. The support block 302 is located below the fixed base 301. A sliding column 303 is fixedly connected to the top of the support block 302. The sliding column 303 is slidably connected to the bottom of the fixed base 301. A moving block 304 is fixedly connected to the top of the sliding column 303. A first support plate 308 is fixedly connected to the top of the moving block 304 by bolts. The outer wall of the first support plate 308 has a connecting groove 309. The top of the moving block 304 is fixedly connected to the second support plate 310 by bolts. The outer wall of the second support plate 310 is fixedly connected to the connecting block 311. The outer wall of the connecting block 311 fits into the inner wall of the connecting groove 309. During system operation, the descent of the moving rod 208 drives the sliding column 303 to move downward through the support block 302. The sliding column 303 pushes the moving block 304 downward along the sliding groove 305 of the fixed seat 301. The downward movement of the moving block 304 drives the moving frame 313 and the spray pipe 314 to descend synchronously through the first support plate 308 and the second support plate 310, preventing strong winds from blowing away water droplets and ensuring heat exchange efficiency. When the wind weakens and the system resets, the moving block 304 rises rapidly under the elastic force of the reset spring 312, driving the entire spray system back to its initial position.

[0020] like Figure 2 , Figure 3 As shown, the fixed seat 301 of the adjusting structure 3 is fixed to the inner wall of the cooling tower body 1 by bolts. A lubricating bushing is provided at the sliding connection between the sliding column 303 and the fixed seat 301 to reduce friction. In the initial state, the moving block 304 of the adjusting structure 3 is in the upper limit position under the elastic force of the return spring 312, and the sprayer 315 of the spray pipe 314 sprays at the default angle to ensure that water droplets evenly cover the packing layer.

[0021] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a limiting block 307 is fixedly connected to the top of the movable block 304. The movable block 304 is engaged with the first support plate 308 via the limiting block 307, and with the second support plate 310 via the limiting block 307. The limiting block 307 of the movable block 304 has a T-shaped structure, and the connecting grooves 309 on the first support plate 308 and the second support plate 310 cooperate to improve the connection stability. This connection method can maintain good structural integrity when the movable block 304 moves up and down, preventing components from loosening.

[0022] like Figure 7 and Figure 8 As shown, a movable frame 313 is fixedly connected to the top of the first support plate 308, and a spray pipe 314 is fixedly connected to the inner wall of the movable frame 313. A sprayer 315 is fixedly connected to the bottom of the spray pipe 314. Multiple stainless steel sprayers 315 are evenly arranged at the bottom of the spray pipe 314, and the spray angle can be adjusted manually or automatically to adapt to different working conditions. The reset spring 312 is compressed during the downward movement of the movable block 304, storing elastic potential energy in preparation for reset.

[0023] like Figure 5 , Figure 6 As shown, the inner wall of the fixed base 301 is provided with a sliding groove 305, and the outer wall of the movable block 304 is fixedly connected with a slider 306. The outer wall of the slider 306 fits into the inner wall of the sliding groove 305. The cooperation between the slider 306 and the sliding groove 305 ensures that the movable block 304 moves smoothly without jamming, making the position adjustment of the spray system more precise and reliable.

[0024] like Figure 5 , Figure 6 As shown, a return spring 312 is fixedly connected to the bottom of the movable block 304, and the end of the return spring 312 away from the movable block 304 is fixedly connected to the inner bottom of the fixed base 301. The return spring 312 is a stainless steel compression spring, and its elastic coefficient is selected according to the total weight of the movable block 304 and the expected stroke to ensure rapid reset. During system operation, the return spring 312 provides a stable reset force, ensuring that the movable block 304 can respond promptly and return to the appropriate position when the wind force changes.

[0025] like Figure 1 and Figure 8As shown, the exhaust structure 4 includes a mounting bracket 401 fixedly connected to the top of the cooling tower body 1. A servo motor 402 is fixedly connected to the inner wall of the mounting bracket 401, and a belt is driven to the output end of the servo motor 402. A support rod 403 is fixedly connected to the top of the cooling tower body 1, and a transmission box 404 is fixedly connected to the top of the support rod 403. An exhaust fan 405 is fixedly connected to the inner wall of the support rod 403, and the outer top wall of the exhaust fan 405 is driven to the servo motor 402 via a belt. During system operation, the servo motor 402 of the exhaust structure 4 adjusts the speed of the exhaust fan 405 in real time according to the air intake signal. When the air intake decreases, the servo motor 402 reduces its speed, and the exhaust volume decreases accordingly to maintain the negative pressure balance inside the tower; when the air intake increases, the servo motor 402 increases its speed to ensure that hot and humid air is discharged in time. In the initial state, the servo motor 402 of the exhaust structure 4 operates at a reference speed, the exhaust fan 405 maintains a normal exhaust volume, the mounting bracket 401 of the exhaust structure 4 is welded from angle steel, and the servo motor 402 is a variable frequency motor, whose output end is connected to the shaft of the exhaust fan 405 via a belt. The support rod 403 is a hollow steel tube with internal wiring, and the transmission box 404 is used to protect the belt drive components. The belt drive system is protected by the transmission box 404 to prevent derailment or interference. The support rod 403 and the mounting bracket 401 provide stable support, reducing vibration and noise during equipment operation.

[0026] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in the initial state of operation, the anemometer continuously monitors the external wind force and transmits the real-time data to the control system. When the wind force is within the normal range, the drive motor 203 is in standby mode, the rotating column 205 is stationary, and the moving rod 208 is located at the upper part of the drive slot 206. At this time, the baffle plate 201 remains open under its own weight and the action of the reset mechanism, the air inlet is fully open, and the cooling tower operates normally. The moving block 304 of the adjusting structure 3 is at its upper limit under the elastic force of the reset spring 312, and the sprayer 315 of the spray pipe 314 sprays at the default angle to ensure that water droplets evenly cover the packing layer. The servo motor 402 of the exhaust structure 4 operates at the reference speed, and the exhaust fan 405 maintains the normal exhaust volume.

[0027] When the anemometer detects excessive wind force, it sends a start signal to the drive motor 203. Upon receiving the signal, the drive motor 203 drives the rotating column 205 to rotate. Since one end of the moving rod 208 is embedded in the drive groove 206 of the rotating column 205, the rotation of the rotating column 205 pushes the moving rod 208 downward along the limiting groove 207 on the fixed frame 204 through the helical contour of the drive groove 206. The downward stroke of the moving rod 208 is controlled by the pitch and rotation angle of the drive groove 206 to ensure accurate response to changes in wind force.

[0028] When the moving rod 208 descends, it drives the connecting rod 209, which is rotatably connected to it, to move downwards. The other end of the connecting rod 209 is rotatably connected to the rotating rod 211, which is fixed to the half gear 210. Therefore, the downward pressure of the connecting rod 209 is transmitted to the rotating rod 211, causing the half gear 210 to rotate. The half gear 210 meshes with the rack 212, and the rotation of the half gear 210 drives the rack 212 to move upwards. The locking pin 213 on the rack 212 is embedded in the locking groove 214 of the adjusting plate 202. The upward movement of the rack 212 drives the adjusting plate 202 to rotate around its rotational connection point with the cooling tower body 1 through the locking pin 213. The adjusting plate 202 is fixedly connected to the baffle plate 201, so the baffle plate 201 rotates accordingly, gradually closing the air inlet, reducing the air intake, and effectively preventing strong winds from disrupting the airflow balance inside the tower.

[0029] Meanwhile, the descent of the moving rod 208 causes the sliding column 303 to move downward via the support block 302. The sliding column 303 pushes the moving block 304 downward along the sliding groove 305 of the fixed seat 301. The downward movement of the moving block 304 causes the moving frame 313 and the spray pipe 314 to descend synchronously via the first support plate 308 and the second support plate 310, preventing strong winds from blowing away water droplets and ensuring heat exchange efficiency. The return spring 312 is compressed during the downward movement of the moving block 304, storing elastic potential energy to prepare for reset. The cooperation between the slider 306 and the sliding groove 305 ensures the smooth movement of the moving block 304.

[0030] When the wind weakens, the anemometer sends a signal again, driving motor 203 to reverse and rotating column 205 to rotate. Movable rod 208 rises under the guidance of drive groove 206, and connecting rod 209 rises accordingly, relieving pressure on rotating rod 211. Half gear 210 rotates under the gravity of rack 212 or the action of auxiliary reset mechanism, driving rack 212 to move downwards, and wind deflector 201 gradually resets to the open state. Movable block 304 rises rapidly under the elastic force of return spring 312.

[0031] The servo motor 402 of the exhaust structure 4 adjusts the speed of the exhaust fan 405 in real time according to the air intake signal. When the air intake decreases, the servo motor 402 reduces its speed, and the exhaust volume decreases accordingly to maintain the negative pressure balance inside the tower; when the air intake increases, the servo motor 402 increases its speed to ensure that hot and humid air is discharged in time. The belt drive system is protected by the transmission box 404 to prevent derailment or interference. The support rod 403 and the mounting bracket 401 provide stable support and reduce vibration.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields.
