Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a cooling tower overflow prevention device. Background Technology

[0002] A cooling tower is a device used to discharge waste heat into the atmosphere. It lowers the water temperature through heat exchange between water and air and is widely used in industrial, commercial, and residential fields. It removes waste heat generated by industrial equipment (such as generators and air conditioning systems) through water circulation, maintaining the system's normal operating temperature.

[0003] Cooling tower overflow refers to the situation where the water in the collection pan or tank exceeds the design capacity, causing water to flow out from the overflow port or tower structure. When cooling tower overflow occurs, it not only wastes water resources but may also damage surrounding equipment and infrastructure. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling tower overflow prevention device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling tower overflow prevention device, comprising an overflow pipe assembly, wherein the overflow pipe assembly is connected to an inclined pipe, the inclined pipe is connected to a water collection tank, a pump body is provided on the outside of the water collection tank, the overflow pipe assembly includes a fixed pipe and an adjusting pipe, a top plate is provided at the top of the adjusting pipe, a plug and a float are provided on the lower end face of the top plate, side plates are provided on both sides of the adjusting pipe, the side plates and the float are connected by springs, one end of the adjusting pipe is slidably embedded in the fixed pipe, and the fixed pipe and the adjusting pipe are fixedly connected by a tightening screw.

[0006] The overflow pipe assembly is installed inside the water tank, while the water collection tank and pump body are both located outside the water tank.

[0007] The lower end face of the plug is in contact with the upper end face of the regulating pipe.

[0008] The water collection tank is equipped with a cover plate at the top, and a liquid level sensor is installed on the cover plate.

[0009] The water collection tank has a first row of pipes and a second row of pipes located on the lower part of its outer side.

[0010] Among them, a solenoid valve is installed on the first row of pipes.

[0011] One end of the pump body is connected to the second row of pipes.

[0012] The other end of the pump body is connected to a return pipe.

[0013] One end of the return pipe extends into the water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention features an overflow pipe assembly inside the water tank. When the water level in the tank rises to its highest point, the upper opening of the regulating pipe automatically opens under the drive of the float, allowing water to automatically overflow through the overflow pipe assembly and be collected by the water collection tank. This prevents water from flowing out of the tower structure and avoids overflow water from damaging surrounding equipment and infrastructure.

[0015] This invention adjusts the height of the overflow port by changing the height of the opening at the top of the regulating pipe. This allows for adjustment of the overflow port height according to actual usage needs, thus meeting various usage requirements.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-5This utility model provides a technical solution: a cooling tower overflow prevention device, including an overflow pipe assembly 1, an inclined pipe 2 connected to the overflow pipe assembly 1, an inclined pipe 2 connected to a water collection tank 3, a pump body 4 provided on the outside of the water collection tank 3, the overflow pipe assembly 1 including a fixed pipe 11 and an adjusting pipe 12, a top plate 13 provided at the top of the adjusting pipe 12, a plug 14 and a float 15 provided on the lower end face of the top plate 13, side plates 16 provided on both sides of the adjusting pipe 12, the side plates 16 and the float 15 are connected by a spring 17, one end of the adjusting pipe 12 is slidably embedded in the fixed pipe 11, and the fixed pipe 11 and the adjusting pipe 12 are fixedly connected by a tightening screw 18.

[0021] The overflow pipe assembly 1 is installed inside the water tank 6, while the water collection tank 3 and the pump body 4 are both located outside the water tank 6. The overflow water is guided and transported through the inclined pipe 2, which can transport the water entering the overflow pipe assembly 1 to the water collection tank 3.

[0022] Overflow pipe assembly 1 is located inside water tank 6. The upper opening of regulating pipe 12 determines the overflow water level. When the water level in water tank 6 is within the normal range, the plug 14 of top plate 13 blocks the upper opening of regulating pipe 12 to prevent water sprayed from the upper water distribution pipe from entering overflow pipe assembly 1. When the water level in water tank 6 rises to its highest point, the water surface contacts float 15. Under the action of buoyancy, float 15 is driven to move upward. The buoyancy is greater than the elastic force, and spring 17 is stretched. Float 15 drives top plate 13 and plug 14, which are fixed to it, to move upward synchronously. At this time, plug 14 is removed, the upper opening of regulating pipe 12 is opened, and water flows automatically. The overflow water enters the regulating pipe 12 of the overflow pipe assembly 1, then enters the fixed pipe 11, then the inclined pipe 2, and finally the collection tank 3. The overflowing water is collected by the collection tank 3. When the water level drops, the float 15 moves down to reset, and the float 15 drives the top plate 13 and the plug 14 to move down and reset simultaneously. The plug 14 re-seals the regulating pipe 12. The overflow pipe assembly 1 is installed in the water tank 6. When the water level in the water tank 6 rises to the highest point, the overflow water automatically overflows through the overflow pipe assembly 1 and is collected by the collection tank 3. This prevents water from flowing out of the tower structure and prevents overflow water from damaging surrounding equipment and infrastructure.

[0023] like Figure 4 As shown, when the tightening screw 18 is loosened, the adjusting tube 12 can slide relative to the fixed tube 11, allowing for flexible adjustment of the extension length of the adjusting tube 12. After adjustment, the tightening screw 18 is tightened to fix it. The extension length of the adjusting tube 12 relative to the fixed tube 11 is adjustable, that is, the position of the upper opening of the adjusting tube 12 is adjustable. By changing the height position of the upper opening of the adjusting tube 12, the height position of the overflow port can be adjusted. The height position of the overflow port can be adjusted according to actual usage needs to meet various usage requirements.

[0024] The lower end face of the plug 14 contacts the upper end face of the regulating pipe 12. When the water level in the water tank 6 is within the normal range, the plug 14 seals the regulating pipe 12, closing the upper opening of the regulating pipe 12.

[0025] The top of the water collection tank 3 is equipped with a cover plate 31, and a liquid level sensor 32 is installed on the cover plate 31 to monitor the water level inside the water collection tank 3 in real time.

[0026] The water collection tank 3 has a first row of pipes 33 and a second row of pipes 34 located on the lower part of its outer side.

[0027] The first pipe 33 is equipped with a solenoid valve 35. When the solenoid valve 35 is open, the first pipe 33 is in the open state. When the solenoid valve 35 is closed, the first pipe 33 is in the closed state.

[0028] The water level inside the water collection tank 3 is monitored in real time by the liquid level sensor 32. When the water level inside the water collection tank 3 is higher than the set value, the solenoid valve 35 opens, and the overflow water inside the water collection tank 3 is discharged through the first drain pipe 33 to the water recycling system. The liquid level sensor 32 is installed in the water tank 6 to monitor the water level inside the water tank 6 in real time. When the water level in the water tank 6 is insufficient, the pump body 4 works to transport the overflow water inside the water collection tank 3 to the return pipe 5. The overflow water flows back to the water tank 6 through the return pipe 5 to achieve water replenishment. When replenishing water, the overflow water inside the water collection tank 3 is used first to improve water utilization and thus save water costs.

[0029] One end of the pump body 4 is connected to the second row of pipes 34. When the pump body 4 is working, it draws out the overflow water inside the water collection tank 3 through the second row of pipes 34.

[0030] The other end of the pump body 4 is connected to the return pipe 5.

[0031] One end of the return pipe 5 extends into the water tank 6. Driven by the pump body 4, the overflow water can flow back to the water tank 6 through the return pipe 5 to replenish the water.

[0032] Working principle: During use, the overflow pipe assembly 1 is installed inside the water tank 6, while the water collection tank 3 and pump body 4 are located outside the water tank 6. The height of the overflow port is adjusted according to actual usage requirements. When the water level in the water tank 6 is within the normal range, the plug 14 of the top plate 13 blocks the upper opening of the regulating pipe 12, preventing water sprayed from the upper water distribution pipe from entering the overflow pipe assembly 1. When the water level in the water tank 6 rises to its highest point, the water surface contacts the float 15. Under the action of buoyancy, the float 15 is driven to move upward, the spring 17 is stretched, and the float 15 drives the top plate 13 and plug 14, which are fixed to it, to move upward synchronously. At this time, the plug 14 is removed, the upper opening of the regulating pipe 12 is opened, and the water flow automatically flows into the regulating pipe 12 of the overflow pipe assembly 1, and then into the fixed pipe 11 through the regulating pipe 12. Pipe 11 enters the inclined pipe 2, and then enters the water collection tank 3 through the inclined pipe 2. When the water level drops, the float 15 moves down to reset. The float 15 drives the top plate 13 and the plug 14 to move down and reset synchronously. The plug 14 re-seals the regulating pipe 12. The water level inside the water collection tank 3 is monitored in real time by the liquid level sensor 32. When the water level inside the water collection tank 3 is higher than the set value, the solenoid valve 35 opens, and the overflow water inside the water collection tank 3 is discharged through the first drain pipe 33 to the water recycling system. A liquid level sensor 32 is installed in the water tank 6 to monitor the water level inside the water tank 6 in real time. When the water level in the water tank 6 is insufficient, the pump 4 works to transport the overflow water inside the water collection tank 3 to the return pipe 5. The overflow water flows back to the water tank 6 through the return pipe 5 to achieve water replenishment. When replenishing water, the overflow water inside the water collection tank 3 is used first.
