The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0020] Please refer to Figures 1 to 4 , in which Figure 1 is a schematic structural diagram of the water-saving and fog-eliminating closed cooling tower, Figure 2 is Figure 1 The enlarged partial structure diagram of part A, Figure 3 is a cross-sectional view of the internal structure of the water-saving and fog-eliminating closed cooling tower, Figure 4 is a schematic diagram of the split structure of the rotating disk and the mounting seat.

[0021] The utility model provides a water-saving and fog-eliminating closed cooling tower, which comprises a cooling tower body 101, a heat exchange tube bundle 102, a spray pipe 103, a circulation pump 104, a demister 105 and a protection mechanism. The protection mechanism comprises two mounting protrusions 106, two rotating assemblies, two rotating discs 107, two connecting rods 108 and two protection plates 109. Each rotating assembly comprises a servo motor 110 and an output gear 111. Through the foregoing solution, the problem that when the existing water-saving and fog-eliminating closed cooling tower is not in use, external impurities may enter the inside of the cooling tower through the air outlet 114 at the top of the tower, and the entry of external impurities into the inside of the cooling tower will affect the use of the entire closed cooling tower can be solved. It can be understood that the foregoing solution can be used in the structure of the water-saving and fog-eliminating closed cooling tower.

[0022] For this specific embodiment, the heat exchange tube bundle 102 is installed inside the cooling tower body 101, the spray pipe 103 is arranged above the heat exchange tube bundle 102, the demister 105 is also arranged at the top end of the cooling tower body 101, the circulation pump 104 is installed on the side of the cooling tower body 101, an input pipe 112 is arranged at the input end of the circulation pump 104, an output pipe 113 is arranged at the output end of the circulation pump 104. The input pipe 112 is located at the inner bottom of the cooling tower body 101, the output pipe 113 is connected to the spray pipe 103. Two air outlets 114 are arranged at the top end of the cooling tower body 101, and exhaust fan blades 115 are installed at each air outlet 114. Starting the circulation pump 104 can cooperate the water at the bottom of the cooling tower body 101 through the input pipe 112 and the output pipe to be circulated and transported into the spray pipe 103, so that the spray pipe 103 sprays water onto the heat exchange tube bundle 102 to cool the heat exchange tube bundle 102. At the same time, air outlets 114 are opened at the top of the cooling tower body 101. Starting the exhaust fan blades 115 can suck cold air in from the louvers arranged on the side of the cooling tower body 101 and discharge hot air from the air outlets 114. And by arranging the demister 105 inside the cooling tower body 101, the wet and hot fog discharged from the air outlets 114 can be reduced, the wet and slippery icing condition around the cooling tower body 101 can be reduced, and the potential safety hazard can be lowered.

[0023] Among them, two mounting protrusions 106 are fixedly installed at the top of the cooling tower body 101. Each mounting protrusion 106 is located on one side of a corresponding air outlet 114. A rotating component is arranged inside each mounting protrusion 106. A rotating disk 107 is rotatably arranged at the port of each mounting protrusion 106. The output end of the rotating component is mechanically transmitted to the rotating disk 107. A connecting rod 108 is arranged on one side of the rotating disk 107. The end of the connecting rod 108 away from the rotating disk 107 is fixedly provided with a protection plate 109. The protection plate 109 is located above the corresponding air outlet 114. When the cooling tower body 101 is not in use, the rotating component is started to drive the rotating disk 107 to rotate at the end of the mounting protrusion 106, so as to drive the protection plate 109 to rotate through the connecting rod 108, so that the protection plate 109 rotates to the top of the corresponding air outlet 114 to shield the air outlet 114, thereby preventing impurities in the external environment from entering the interior of the cooling tower body 101 through the air outlet 114 when the cooling tower body 101 is not in use, which affects the use of the entire closed cooling tower.

[0024] Secondly, a transmission tooth part 116 is arranged on the surface of each rotating disk 107 close to the corresponding mounting protrusion 106. The servo motor 110 is installed inside the mounting protrusion 106. An output gear 111 is arranged at the output end of the servo motor 110. The output gear 111 is meshed with the transmission tooth part 116. The servo motor 110 is started to drive the output gear 111 to rotate. Since the output gear 111 is meshed with the transmission tooth part 116, the rotating disk 107 is driven to rotate at the end of the mounting protrusion 106.

[0025] Moreover, the number of teeth of the transmission tooth part 116 is greater than that of the output gear 111. The transmission tooth part 116 is used to slow down the output speed, so that the rotating disk 107 rotates relatively slowly on the mounting protrusion 106, which is convenient for control. A wiring hole 117 is arranged on the side surface of each mounting protrusion 106. Through the arrangement of the wiring hole 117, the wiring of the servo motor 110 is completed.

[0026] At the same time, a heat dissipation plate 118 is arranged on the outer side wall of each mounting protrusion 106. A heat dissipation groove 119 is arranged on the heat dissipation plate 118. The heat dissipation groove 119 corresponds to the servo motor 110. Through the arrangement of the heat dissipation groove 119, the interior of the mounting protrusion 106 is kept in communication with the external air, so that the heat generated by the servo motor 110 during operation is taken away by the flowing air to dissipate heat from the servo motor 110.

[0027] In addition, a filter screen 120 is inserted into each side of each heat dissipation plate 118 extending to the outside of the mounting protrusion 106. The filter screen 120 corresponds to the heat dissipation groove 119. A handle 121 is provided at one end of the filter screen 120 extending to the outside of the heat dissipation plate 118. Through the arrangement of the filter screen 120, dust in the air is filtered to prevent excessive dust from entering the inside of the mounting protrusion 106 through the heat dissipation groove 119. Through the arrangement of the handle 121, the disassembly and assembly of the filter screen 120 are made more convenient.

[0028] When using the water-saving and fog-eliminating closed cooling tower of the present utility model, starting the circulation pump 104 can circulate and transport the water at the bottom of the cooling tower body 101 through the cooperation of the input pipe 112 and the output reference pipe to the spray pipe 103, so that the spray pipe 103 sprays water onto the heat exchange tube bundle 102 to cool the heat exchange tube bundle 102. At the same time, an air outlet 114 is provided at the top of the cooling tower body 101. Starting the exhaust fan blade 115 can suck cold air in from the louver provided on the side of the cooling tower body 101 and discharge hot air from the air outlet 114. And by providing the demister 105 inside the cooling tower body 101, the wet and hot mist discharged from the air outlet 114 can be reduced, the wet and slippery icing around the cooling tower body 101 can be reduced, and the potential safety hazard can be lowered. And when the cooling tower body 101 is not in use, starting the rotating assembly drives the rotating disk 107 to rotate at the end of the mounting protrusion 106, so as to drive the protection plate 109 to rotate through the connecting rod 108, so that the protection plate 109 rotates to the top of the corresponding air outlet 114 to shield the air outlet 114, thereby preventing impurities in the external environment from entering the inside of the cooling tower body 101 through the air outlet 114 when the cooling tower body 101 is not in use, which affects the use of the entire closed cooling tower.

Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
