Description

Technical Field

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by using water to exchange heat with air to generate steam. The steam evaporates and carries away heat, thus achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thereby lowering the water temperature and ensuring the normal operation of the system.

[0003] Chinese patent CN219757036U provides an energy-saving cooling tower, including a wind box. A pump is fixedly connected to the bottom of the wind box, and a water inlet pipe is fixedly connected to the pump outlet. However, in order to ensure the normal operation of the equipment during use, it is necessary to adjust the temperature and flow rate of the water in the water inlet pipe by analyzing the data detected by the temperature sensor. However, the temperature sensor is prone to damage when immersed in water for a long time. During maintenance, the water pipe needs to be removed, which is a lot of work and inconvenient. In addition, there is no collection of evaporated water. During use, a large amount of water resources will be converted into water vapor, which will cause waste of water resources.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1-3A temperature control system for a cooling tower includes a tower body 1. A vent pipe 5 is fixedly connected to the top of the tower body 1, and a condensation mechanism 7 is installed on the vent pipe 5. A base 2 is fixedly connected to the bottom of the tower body 1, and a drain pipe 6 is fixedly connected to the middle of the bottom end of the base 2. Two sets of columns 3 are fixedly connected to the bottom end of the base 2 to support the tower body 1. A collection trough 4 is provided below the drain pipe 6. A water inlet pipe 8 is installed on the tower body 1. A sensing mechanism 11 is installed. A pump 14 is fixedly connected to the top of the water inlet pipe 8, and several sets of evenly distributed nozzles 15 are fixedly connected to the bottom of the water inlet pipe 8. The pump 14 pressurizes the water in the water inlet pipe 8 and passes it through the nozzles 15. The water is cooled by the packing material 16. Then the heat dissipation mechanism 13 operates, driving airflow to efficiently cool the water in the packing material 16. The cooled water is then discharged from the drain pipe 6 and falls into the collection tank 4 for collection.

[0026] The sensing mechanism 11 includes a housing 1101 with a mounting groove 1102. An electric telescopic rod 1103 is mounted on the housing 1101. A sealing plate 1104 is fixedly connected to the output end of the electric telescopic rod 1103. The sealing plate 1104 is slidably connected to the mounting groove 1102, and the sealing plate 1104 is sealed to the mounting groove 1102. By installing the sensing mechanism 11 inside the water inlet pipe 8, the inlet water temperature of the cooling tower is monitored. After analysis by the PLC, it is determined whether the cooling tower's operating efficiency is abnormal, and the water flow rate is controlled. By driving the electric telescopic rod 1103, the sealing plate 1104 slides along the mounting groove 1102, keeping the inside of the housing 1101 sealed, facilitating the replacement of the temperature sensor body 1109.

[0027] A first electric motor 1105 is installed on the outer shell 1101. The output end of the first electric motor 1105 passes through the outer shell 1101 and is fixedly connected to a scraper 1106. By driving the first electric motor 1105 to rotate, the scraper 1106 swings along the surface of the outer shell 1101 to clean the probe of the temperature sensor body 1109, preventing some impurities from remaining on the temperature sensor body 1109 and affecting the accuracy of its detection data.

[0028] A second electric motor 1107 is fixedly connected to the outer casing 1101. A mounting plate 1108 is fixedly connected to the output end of the second electric motor 1107. The mounting plate 1108 is rotatably connected to the outer casing 1101. By driving the second electric motor 1107 to rotate, the mounting plate 1108 is rotated, causing the faulty temperature sensor body 1109 to move away from the mounting groove 1102 until the intact temperature sensor body 1109 is aligned with the mounting groove 1102.

[0029] Several sets of evenly distributed temperature sensor bodies 1109 are slidably connected to the mounting plate 1108. A sealing strip is fitted around the outside of each temperature sensor body 1109, and the diameter of each temperature sensor body 1109 is the same as the diameter of the mounting groove 1102. An electric push rod 1110 is fixedly connected to the outer shell 1101. The electric push rod 1110 is correspondingly set with the mounting groove 1102. By setting the electric push rod 1110, the temperature sensor body 1109 is driven to slide along the mounting plate 1108, pass through the mounting groove 1102 and exit the outer shell 1101 to monitor the inlet water temperature of the cooling tower.

[0030] In this embodiment, a sensing mechanism 11 is installed inside the inlet pipe 8 to monitor the inlet water temperature of the cooling tower. After analysis by the PLC, it is determined whether the cooling tower's operating efficiency is abnormal, and the water flow rate is controlled. By driving the first electric motor 1105 to rotate, the scraper 1106 swings along the surface of the outer shell 1101 to clean the probe of the temperature sensor body 1109, preventing impurities from remaining on the temperature sensor body 1109 and affecting the accuracy of its detection data. When the temperature sensor body 1109 is damaged, the electric telescopic rod 1103 drives the sealing plate 1104 to slide along the mounting groove 1102, causing the outer shell 1101 to... The interior is sealed, facilitating the replacement of the temperature sensor body 1109. By driving the second electric motor 1107 to rotate, the mounting plate 1108 is rotated, moving the faulty temperature sensor body 1109 away from the mounting groove 1102 until the intact temperature sensor body 1109 is aligned with the mounting groove 1102. By driving the electric push rod 1110, the temperature sensor body 1109 slides along the mounting plate 1108, passing through the mounting groove 1102 and exiting the outer casing 1101 to monitor the inlet water temperature of the cooling tower. This completes the replacement of the temperature sensor body 1109 without disassembling the inlet pipe 8, which helps reduce the frequency and difficulty of equipment maintenance. Example

[0031] Please see Figure 1-4This embodiment provides a technical solution based on Embodiment 1: The condensation mechanism 7 includes a condenser plate 701, one end of which is fixedly connected to a water outlet pipe 703, and the other end of which is fixedly connected to a water inlet pipe 702. The other end of the water outlet pipe 703 is fixedly connected to an expansion tank 704. A set of connecting pipes 707 is fixedly connected to the bottom of the expansion tank 704. The other end of the set of connecting pipes 707 is fixedly connected to a cooler 705. Another set of connecting pipes 707 is fixedly connected to the cooler 705, and the other end of the connecting pipes 707 is connected to a water pump 706. The water pump 706 is fixedly connected to the water inlet pipe 702. The expansion tank 704 is mainly used to compensate for the volume expansion and contraction of the coolant due to temperature changes. The cooler 705 dissipates the heat in the coolant through heat exchange with the outside air, thereby lowering the coolant temperature. The cooler 705 is equipped with a filter mechanism to prevent contaminants from circulating in the system, avoiding wear and blockage to the engine and other components, ensuring the cleanliness of the coolant, and extending the service life of the system components. The water pump 706 drives the coolant to circulate in the system to cool the condenser plate 701.

[0032] The top of the vent pipe 5 is provided with guide grooves 12 on both sides. The depth of the guide grooves 12 gradually decreases from front to back. A condenser plate 701 is fixedly connected to the top of the vent pipe 5. One side of the guide groove 12 is in contact with the inner wall of the condenser plate 701. The condenser plate 701 is an arc-shaped plate. When water vapor encounters the cold, it will condense into water droplets and slide down the surface of the condenser plate 701 into the guide groove 12.

[0033] A connecting pipe 9 is fixedly connected to the front end of the tower body 1. One end of the connecting pipe 9 is installed at the bottom of the output end of the guide groove 12, and the other end of the connecting pipe 9 is set above the collection tank 4. By setting the connecting pipe 9, the collected water is transported to the collection tank 4, which makes it convenient for staff to process and reuse the water, thus improving the utilization rate of water resources.

[0034] Two sets of symmetrically arranged ventilation slots 10 are respectively opened on both sides of the base 2. A filter screen is fixedly connected to the ventilation slot 10. A heat dissipation mechanism 13 is installed inside the ventilation pipe 5. The heat dissipation mechanism 13 includes a servo motor and a heat dissipation fan blade. A packing 16 is installed inside the tower body 1. The packing 16 is located below the water inlet pipe 8. The output shaft of the servo motor is connected to the heat dissipation fan blade through a coupling. By driving the servo motor to move, the heat dissipation fan blade is rotated, which extracts the air in the tower body 1 and then performs air circulation. During the air circulation process, the water is cooled by air.

[0035] In this embodiment, the condenser plate 701 is an arc-shaped plate made of stainless steel. Water vapor condenses into water droplets upon cooling, sliding down the surface of the condenser plate 701 into the guide groove 12, and then through the connecting pipe 9 into the collection tank 4. This helps reduce water waste caused by evaporation. The expansion tank 704 is mainly used to compensate for the volume expansion and contraction of the coolant due to temperature changes. The cooler 705 dissipates heat from the coolant through heat exchange with the outside air, lowering the coolant temperature. The cooler 705 has a filter mechanism to prevent contaminants from circulating within the system, avoiding wear and blockage to the engine and other components, ensuring coolant cleanliness, and extending the service life of system components. The water pump 706 drives the coolant to circulate within the system, cooling the condenser plate 701 and ensuring it remains at a low temperature, thus improving water vapor condensation.
