Description

Technical Field

[0002] During the operation of the wet cooling unit, the cooling tower often has severe icing and ice accumulation when the ambient temperature is low, especially in severe cold areas, resulting in poor cooling effect of the cooling tower. In more serious cases, it will cause the fillers and beams in the water tower to fall, threatening the safe operation of the generator set. At present, the antifreeze measures for cooling towers mainly include: adding windshields. Considering the variability of the operating conditions of the generator set, most power plants use windshields for antifreeze. The windshield is located on the periphery of the cooling tower, and the size of the windshield is fixed. However, due to the constant changes in ambient temperature and wind direction, the windshield needs to be disassembled and assembled to meet the antifreeze requirements. The disassembly and assembly process is cumbersome, resulting in a long adjustment time, resulting in greater safety hazards and poor antifreeze reliability. In addition, the windshield is hung when antifreeze is needed, and the windshield is removed when antifreeze is not needed. Due to the large number of windshields, the operation is complicated and the labor intensity of the staff is high. Summary of the invention

[0036] Specifically, the basic support unit 100 includes a cooling tower 101, an antifreeze assembly 102 disposed on the periphery of the cooling tower 101, an antifreeze ceiling 103 disposed on the top of the antifreeze assembly 102, and a lintel 104 disposed on the bottom of the antifreeze ceiling 103;

[0037] The driving control unit 200 includes a driving assembly 201, a connecting rod 202 disposed at the bottom of the driving assembly 201, and an antifreeze baffle 203 capable of rotating independently;

[0038] The antifreeze baffles 203 are sequentially arranged along the circumference of the cooling tower 101 , and support frames are arranged on both sides of the antifreeze baffles 203 , on which the drive assembly 201 is fixedly mounted.

[0039] Furthermore, the support frame includes support rods 203 a arranged on both sides of the antifreeze baffle 203 , and the support rods 203 a are fixedly connected to both ends of the antifreeze baffle 203 .

[0040] Preferably, the antifreeze assembly 102 of the basic support unit 100 is arranged outside the cooling tower, and a complete antifreeze structure is formed between the two. The driving assembly 201 drives the antifreeze baffle 203 to rotate through the connecting rod 202. The antifreeze baffle 203 is arranged in sequence along the circumference of the cooling tower 101, which can provide all-round protection for the cooling tower 101. The support frame is arranged on both sides of the antifreeze baffle 203 to support the stable installation of the driving assembly 201.

[0041] Furthermore, the driving assembly 201 includes an electric actuator, which drives the antifreeze baffle 203 to rotate through the connecting rod 202. The antifreeze baffle 203 is made of a light hard material and is used to resist external cold air.

[0042] Furthermore, the driving component 201 responds after receiving the command, and drives the antifreeze baffle 203 to rotate through the connecting rod 202, wherein the antifreeze baffle 203 is in a fully open state in a horizontal position and in a fully closed state in a vertical position.

[0043] Preferably, the support rod 203a and the two ends of the antifreeze baffle 203 are fixedly connected to improve the stability of the antifreeze baffle 203 when rotating. The driving component 201 uses an electric actuator to drive the antifreeze baffle 203 to rotate through the connecting rod 202 to achieve precise opening control. The antifreeze baffle 203 is made of light hard material, which can not only meet the windproof requirements, but also reduce the rotation load, which is conducive to improving the adjustment efficiency.

[0044] Furthermore, the antifreeze assembly 102 is enclosed by a plurality of groups of antifreeze baffles 203 to form a regular polygonal structure and is evenly distributed along the periphery of the cooling tower 101 , and each group of antifreeze baffles 203 can independently adjust the opening degree.

[0045] Furthermore, the driving component 201 is provided with an opening display device for displaying the current opening of the antifreeze baffle 203 ; and a control key is also provided for controlling the action of the driving component 201 .

[0046] Preferably, the working mode of the driving component 201 is to give feedback after receiving the instruction, and drive the antifreeze baffle 203 to rotate through the connecting rod 202. The antifreeze baffle 203 adopts a design scheme in which the horizontal position is fully open and the vertical position is fully closed, making the opening control more intuitive. The antifreeze component 102 adopts a design scheme in which multiple antifreeze baffles 203 are enclosed in a regular polygon structure, which are evenly distributed along the periphery of the cooling tower 101. Each antifreeze baffle 203 can independently adjust the opening, which is conducive to targeted adjustment according to wind conditions in different directions.

[0047] Furthermore, the opening size of the antifreeze baffle 203 is used to control the ventilation volume, thereby adjusting the circulating water temperature; the rotation angle range of the antifreeze baffle 203 is 0-90 degrees, 0 degrees is a vertical state, and 90 degrees is a horizontal state.

[0048] Furthermore, a sealing connection structure is provided between the antifreeze component 102 and the antifreeze ceiling 103, and a sealing connection structure is provided between the lintel 104 and the antifreeze component 102, so as to prevent cold air from entering.

[0049] Preferably, an opening display device is provided on the drive assembly 102, which can display the current opening of the antifreeze baffle 203 in real time, facilitating precise control. The setting of the control key makes the operation more convenient and can accurately control the action of the drive assembly. The opening size of the antifreeze baffle 203 directly controls the ventilation volume, thereby affecting the circulating water temperature. The rotation angle range is set to 0-90 degrees, where 0 degrees is a vertical state and 90 degrees is a horizontal state, and the angle control is more intuitive.

[0050] Furthermore, the driving assembly 201 includes a fixing seat fixedly mounted on the support frame, the fixing seat is provided with a rotating shaft, the rotating shaft is fixedly connected to the antifreeze baffle 203, and the rotating shaft is mounted on the support frame through the fixing seat.

[0051] Preferably, a sealed connection structure is used between the antifreeze assembly 102 and the antifreeze ceiling 103, and between the door lintel 104 and the antifreeze assembly 102 to form a complete sealed space. This design effectively prevents cold air from entering and improves the antifreeze effect. The top of the antifreeze assembly 102 is fixedly connected to the antifreeze ceiling 103, and the bottom is fixedly connected to the door lintel 104, and the three form a complete antifreeze structure. The rotation of the antifreeze baffle 203 does not affect the overall sealing, ensuring the continuity of the antifreeze effect.

[0052] Furthermore, the top of the antifreeze component 102 is fixedly connected to the antifreeze ceiling 103, and the bottom of the antifreeze component 102 is fixedly connected to the door lintel 104, forming a complete antifreeze structure between the three, and the rotation of the antifreeze baffle 203 does not affect the overall sealing.

[0053] It should be noted that the overall structure of the antifreeze assembly 102 is a regular polygon and is evenly distributed around the cooling tower. The antifreeze ceiling 103 is sealed to the top of the antifreeze assembly 102, and the lintel 104 is also sealed to the bottom of the antifreeze assembly 102 to form a complete antifreeze structure. The opening display device provided on the drive assembly 102 can display the opening angle of the antifreeze baffle in real time, and the control key is used to control the action of the drive assembly. The rotation angle range of the antifreeze baffle is 0-90 degrees. When it is in a vertical state of 0 degrees, it is in a fully closed state, and when it is in a horizontal state of 90 degrees, it is in a fully open state.

[0054] When in use, the present invention forms a complete antifreeze structure through the basic support unit 100, wherein the antifreeze assembly 102, the antifreeze ceiling 103 and the door lintel 104 are sealed and connected to effectively prevent cold air from entering. By providing a group of antifreeze baffles 203 that can rotate independently, the driving component 201 is used to drive the opening of the antifreeze baffles 203. When the ambient temperature and wind direction change, the opening of each antifreeze baffle 203 can be directly adjusted by the driving component 201. Compared with the prior art of adjusting by disassembling and assembling the windshield, the adjustment operation is simplified, the adjustment time is shortened, and the antifreeze reliability is effectively improved. When the ventilation volume needs to be adjusted, the driving component 201 drives the antifreeze baffles 203 to rotate through the connecting rod 202, and each group of antifreeze baffles 203 can adjust the opening independently. The antifreeze baffle 203 rotates stably under the support of the support rods 203a on both sides, and the rotation angle range is 0-90 degrees. The ventilation volume is controlled by changing the opening size, and then the circulating water temperature is adjusted, which effectively solves the problem of ice formation and ice accumulation in the cooling tower in cold weather. Since the antifreeze baffle is made of light hard material, it not only ensures the windproof effect, but also reduces the rotation load and improves the adjustment efficiency. The whole device is simple to operate and easy to adjust, avoiding the problem of frequent disassembly and assembly of traditional fixed baffles.

[0055] According to the temperature of the circulating water in the tower pool, the control room sends a command on the computer to act on the electric actuator of the drive component 201, and the electric actuator gives feedback to drive the connecting rod 202, which drives the first rotating rod 204 again, and drives the second rotating rod 205 to rotate again. The rotation of the second rotating rod 205 drives the antifreeze baffle 203 to rotate, and the antifreeze baffle 203 rotates to the horizontal position to the fully open position and the vertical position to the fully closed position. The opening degree of the antifreeze baffle 203 controls the ventilation volume, thereby controlling the temperature of the circulation.

[0056] In summary, the present invention realizes all-round protection of the cooling tower by arranging an antifreeze component on the periphery of the cooling tower and equipping an independently rotatable antifreeze baffle, which effectively solves the problem of circulating water freezing in the existing cooling tower in cold weather. The antifreeze baffle can adjust the opening as needed, and adjust the circulating water temperature by controlling the ventilation volume, avoiding the defect of inconvenient adjustment of the traditional fixed baffle. By setting a drive control unit, including a drive component and a connecting rod mechanism, the rotation of each group of antifreeze baffles can be independently controlled, and precise adjustment can be achieved through an opening display device and a control key. Compared with the fixed baffle of the prior art, the adjustment operation is simplified, the cumbersome process of frequent disassembly and assembly of the baffle is avoided, the adjustment time is effectively shortened, and the antifreeze efficiency is improved. The antifreeze component, the antifreeze ceiling and the lintel form a complete antifreeze structure, which effectively prevents cold air from entering the interior of the cooling tower through a sealed connection method, avoids direct contact between cold air and circulating water, and reduces the risk of circulating water freezing. The setting of the support frame makes the rotation of the antifreeze baffle more stable and reliable, the installation position of the drive component is convenient for maintenance, the overall structure is reasonable, and the installation is convenient. The antifreeze baffle is made of light and hard material, which not only ensures the windproof effect but also reduces the rotation load.
