Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a protective structure of a cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] The existing protective structure of the cooling tower only relies on its own legs for support. If you want the legs to be stable, you need to install the legs on the cement with screws. This method is easy to damage the ground and is not convenient for installation. If only the legs are used for installation, the stability will be reduced, which cannot meet people's use needs.

[0004] The existing patent (publication number: CN219607829U) is a cooling tower protection device. This utility model drives the movable pin to rotate through an elastic belt, so that the auxiliary frame drives the gripping spikes to grip the ground, thereby increasing the gripping ability of the equipment without damaging the ground. This structure is most effective on the soil ground. On the soil ground, the auxiliary frame and the gripping spikes will extend into the soil, increasing the resistance of the auxiliary frame, thereby increasing the stability of the cooling tower body.

[0005] In view of the above problems, existing patents have provided solutions, but the air outlet of the cooling tower body is always open and lacks protective measures, resulting in rainwater easily entering the cooling tower from the top into the cooling tower when encountering severe weather such as strong winds, heavy rains and hail, causing pollution to the circulating water inside the cooling tower.

[0006] Therefore, a protective structure of a cooling tower is proposed. Utility Model Content

[0007] The utility model aims to provide a protective structure for a cooling tower, which can solve the problem that the air outlet of the existing cooling tower body is always open and lacks protective measures, resulting in rainwater easily entering the interior of the cooling tower from the top of the cooling tower when encountering severe weather such as strong winds, heavy rain and hail, causing pollution to the circulating water inside the cooling tower.

[0008] To achieve the above object, the utility model provides the following technical solution: a protective structure of a cooling tower, comprising a cooling tower body, the top of the cooling tower body is fixedly connected with an air outlet pipe connected to the cooling tower body, and the top of the air outlet pipe is provided with a protective mechanism;

The protective cover 301 is arranged at the top of the air outlet duct 2. The four fixed plates 302 are fixedly connected to the side walls of the air outlet duct 2 and are equidistantly distributed in a circle.

[0035] Specifically, Figure 1 As shown, a ladder 9 is provided on one side of the cooling tower body 1 , and a guardrail 10 is fixedly connected to the side wall of the ladder 9 .

[0036] Specifically, Figure 6 As shown, a fixed base frame 11 is fixedly connected to the bottom of the cooling tower body 1 , and two side walls of the fixed base frame 11 are fixedly connected to two mounting ears 12 .

[0037] When in use, the protective cover 301 is plugged into the threaded column 303 on the fixing plate 302 through the through hole 305 on the connecting plate 304, so that the protective cover 301 and the air outlet pipe 2 are connected as a whole, and then the locking nut 306 is screwed on the threaded column 303, so that the connecting plate 304 and the fixing plate 302 can be locked and fixed. The protective cover 301 can not only prevent external rainwater and floating objects from entering the cooling tower body 1 through the air outlet pipe 2 in heavy rain and windy weather, ensuring that the circulating water inside the cooling tower body 1 will not be polluted, but also prevent hail from hitting the motor and blades inside the cooling tower body 1 and causing damage to them in hail weather, thereby The cooling tower body 1 can be effectively protected. The gas inside the cooling tower body 1 will be discharged to the outside through the multiple exhaust ports 7 on the protective cover 301. The filter 8 can be used to filter the gas entering the cooling tower body 1, and at the same time, prevent debris from entering the cooling tower body 1 through the exhaust port 7. The ladder 9 is provided to facilitate the staff to climb to the top of the cooling tower body 1 for inspection or installation. The guardrail 10 can be provided to protect the staff during the climbing process. The expansion bolts are used in conjunction with the mounting ears 12 to fix the fixed base frame 11 at the specified position, thereby ensuring the stability of the cooling tower body 1.

[0038] Specifically, Figure 3 As shown, the buffer assembly 307 includes a fixed sleeve 3071, a movable rod 3072, a limiting plate 3073, a spring 3074 and a top plate 3075. The multiple fixed sleeves 3071 are fixedly connected to the top of the protective cover 301 and are equidistantly distributed around the circumference. The movable rod 3072 passes through the fixed sleeve 3071 and is slidably connected to the fixed sleeve 3071. The limiting plate 3073 is arranged inside the fixed sleeve 3071 and is fixedly connected to the bottom of the movable rod 3072. One end of the spring 3074 is fixedly connected to the bottom of the limiting plate 3073, and the other end of the spring 3074 is fixedly connected to the inner bottom of the fixed sleeve 3071.

The staff can climb to the top of the cooling tower body 1 through the ladder 9, and then plug the protective cover 301 through the through hole 305 on the connecting plate 304 and the threaded column 303 on the fixing plate 302, so that the protective cover 301 is connected to the air outlet pipe 2 as a whole, and then the locking nut 306 is screwed on the threaded column 303, so that the connecting plate 304 and the fixing plate 302 can be locked and fixed. The protective cover 301 can not only prevent external rainwater and floating objects from entering the cooling tower body 1 through the air outlet pipe 2 during heavy rain and strong winds, ensuring that the circulating water inside the cooling tower body 1 will not be polluted, but also can be used in hail weather. In order to prevent hail from hitting the motor and blades inside the cooling tower body 1 and causing damage to them, the cooling tower body 1 can be effectively protected. The gas inside the cooling tower body 1 will be discharged to the outside through the multiple exhaust ports 7 on the protective cover 301. By setting the filter 8, the gas entering the cooling tower body 1 can be filtered, and at the same time, debris can be prevented from entering the cooling tower body 1 through the exhaust port 7. When the top of the protective cover 301 is hit by a heavy object, the impact force will first act on the top plate 3075, and the top plate 3075 will move along the trajectory of the fixed sleeve 3071 through the moving rod 3072 and the limiting plate 3073. At this time, the spring 3074 is in a contracted state, and the deformation force of the spring 3074 plays a buffering role, which can offset the impact force and improve the protection performance of the protective cover 301.
