[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0022] As Figures 1 to 3As shown in the figure, a closed cooling tower that is easy to install includes a cooling tower main body 1. The closed cooling tower further includes a fixing component, which includes a frame body 2 arranged at the bottom of the cooling tower main body 1 and a plurality of fixing legs 3 that are synchronously slidably arranged on the frame body 2. Among them, the bottom of the cooling tower main body 1 can be welded or locked to the frame body 2. The plurality of fixing legs 3 are located around the frame body 2. A fixing block 4 is arranged at the bottom of each fixing leg 3, and a fixing hole 41 is arranged on each fixing block 4.

[0023] When the easy-to-install closed cooling tower of this embodiment is in use, the closed cooling tower is installed and fixed on the working ground through the frame body 2, the plurality of fixing legs 3, and the fixing blocks 4. Specifically, the frame body 2 is moved and placed on the working ground. Then, the plurality of fixing legs 3 slide downward simultaneously so that the fixing blocks 4 contact the working ground. At this time, the fixing blocks 4 also contact the outer wall of the frame body 2. Because the fixing holes 41 are arranged on the fixing blocks 4, the fixing holes 41 on the fixing blocks 4 can be quickly fixed to the working ground through nuts and bolts, thereby fixing the fixing blocks 4, the fixing legs 3, and the frame body 2 to the working ground, and finally fixing the closed cooling tower to the working ground. When the closed cooling tower needs to be transferred to other workstations and before the next installation and fixation, the plurality of fixing legs 3 slide upward simultaneously so that the fixing blocks 4 are separated from the working ground, and the fixing blocks 4 do not affect the overall transfer of the closed cooling tower.

[0024] The easy-to-install closed cooling tower of this embodiment replaces the method of fixing by multiple people. The plurality of fixing legs 3 and the fixing blocks 4 can slide simultaneously. After the plurality of fixing blocks 4 contact the working ground, the operator only needs to quickly fix the fixing holes 41 on the fixing blocks 4 to the working ground through nuts and bolts, which greatly speeds up the overall installation and fixation speed of the closed cooling tower.

[0025] As an implementable manner, slide rails 21 are arranged on the periphery of the frame body 2. Sliders 2 are slidably arranged on the slide rails 21 and the sliders 2 are fixedly connected to one end of the fixing legs 3 away from the fixing blocks 4. Synchronous rods 23 are fixedly connected between adjacent sliders 2. A cylinder 6 is arranged on the frame body 2. The cylinder 6 is arranged at the bottom of the frame body 2 and the cylinder 6 is located between two sliders 2. The telescopic rod of the cylinder 6 is fixedly connected to the synchronous rod 23 and can drive it to slide up and down. When the cylinder 6 is started, it drives the synchronous rod 23 to slide up and down, and the sliders 2 slide up and down relative to the slide rails 21, thereby realizing the up and down sliding of other synchronous rods 23, the plurality of fixing legs 3, and the fixing blocks 4.

[0026] As an implementable manner, the fixing component further includes a plurality of fixing columns 5 having the same number as the fixing holes 41. Each fixing block 4 is provided with a fixing groove 42. The bottom of the fixing column 5 is threadedly connected to the fixing groove 42 or the fixing hole 41; a pin hole is provided at the top of the fixing column 5, and a pin shaft 51 is inserted through the pin hole. Wherein, an external thread is provided on the fixing column 5, and an internal thread matching the external thread is provided on the inner wall of the fixing groove 42 or the fixing hole 41.

[0027] First, when the fixing column 5 is not in use, the fixing column 5 is fixed on the fixing groove 42. The setting of the fixing groove 42 can prevent the loss of the fixing column 5. When the fixing block 4 needs to be fixed, the fixing column 5 is taken off from the fixing groove 42, and the fixing column 5 is threadedly connected to the fixing hole 41 on the fixing block 4. The fixing column 5 finally fixes the fixing block 4 on the working ground, which can speed up the installation and fixing speed.

[0028] After the fixing column 5 is threadedly connected to the fixing hole 41 on the fixing block 4, the pin shaft 51 passes through the pin hole, and the pin shaft 51 limits the fixing column 5 to prevent the fixing column 5 from loosening, thereby causing the fixing block 4 to not be stably fixed on the working ground.

[0029] As an implementable manner, each fixing block 4 is provided with a slot, an insertion plate 43 is inserted into the slot, and one end of the insertion plate 43 is located outside the slot. A ground gripping claw 431 is provided at the end of the insertion plate 43 located outside the slot, and the ground gripping claw 431 has a structure that is wider at the top and narrower at the bottom. When the fixing block 4 contacts the soil working ground, the insertion plate 43 is inserted into the slot. At this time, the ground gripping claw 431 on the insertion plate 43 contacts the working ground and the ground gripping claw 431 can grip the working ground, further stably fixing the fixing block 4 on the working ground.

[0030] As an implementable manner, the cooling tower main body (1) includes a box body (11) provided on a frame body (2) and a heat exchanger (12), a spray main pipe (13) and a circulation water tank (14) provided in the box body (11).

Water pumps (7) are provided on both the circulation water inlet pipe (141) and the heat exchange water inlet pipe (121). The circulation water tank (14) is located below the heat exchanger (12) and the spray main pipe (13). The circulation water tank (14) is connected to one end of a circulation water outlet pipe (142), and the other end of the circulation water outlet pipe (142) extends out of the box body (11). Wherein, both the circulation water inlet pipe (141) and the circulation water outlet pipe (142) are connected to an external water tank for storing cooling water. A ventilation opening is provided at the top of the box body (11).

[0031] When the cooling tower main body 1 conducts heat exchange operations, two water pumps 7 are started. Cooling water enters the spray main pipe 13 through the circulating inlet pipe 141, and the hot water to be heat-exchanged enters the heat exchanger 12 through the heat exchange inlet pipe 121. The cooling water finally sprays out from multiple spiral nozzles 131 on the spray main pipe 13. The cooling water exchanges heat with the hot water in the heat exchanger 12, and the generated hot air is discharged through the ventilation opening at the top of the box body 11; the hot water after heat exchange cools down and is discharged from the heat exchange outlet pipe 122, waiting for the next operation; the cooling water after heat exchange becomes hot and enters the circulating water tank 14, and finally returns to the external water tank again through the circulating outlet pipe 142, and the cooling water can be recycled.

[0032] Furthermore, a fan is arranged outside the box body 11, and the air outlet of the fan faces the ventilation opening. When the fan is started, it can make the hot air in the box body 11 circulate with the external air, accelerating the heat dissipation in the box body 11.

[0033] As an implementable mode, the heat exchanger 12 is a spiral loop pipe. The bottom of the spray main pipe 13 is arranged in the box body 11 through a support frame 15, and a first sealing plug is arranged at the bottom of the spray main pipe 13. The middle part of the spray main pipe 13 is located at the central position of the heat exchanger 12, and the top of the spray main pipe 13 extends out of the box body 11. Multiple spiral nozzles 131 are arranged along the circumferential direction of the spray main pipe 13. When the cooling water sprays out from the multiple spiral nozzles 131 on the spray main pipe 13, the multiple spiral nozzles 131 arranged circumferentially can realize the cooling heat exchange of the heat exchanger 12. By adopting the spiral nozzles 131, the multiple spiral nozzles 131 ensure that the sprayed cooling water can completely cover the surface of the heat exchanger 12, and the cooling effect is better.

[0034] Furthermore, the support frame 15 is arranged in the box body 11 and above the circulating water tank 14. The support frame 15 includes a ring frame arranged in the box body 11 and a convex block arranged at the center of the ring frame through a reinforcing rib. The bottom of the spray main pipe 13 is arranged on the convex block. The support frame 15 does not affect the cooling water after heat exchange from becoming hot and entering the circulating water tank 14.

[0035] As an implementable manner, the cooling tower main body 1 further includes a plurality of spray branch pipes 16. The plurality of spray branch pipes 16 are arranged in a ring on the ring frame and are located outside the heat exchanger 12. A second sealing plug is provided at the bottom of each spray branch pipe 16. A plurality of spray nozzles 161 facing the heat exchanger 12 are provided in the middle of each spray branch pipe 16. The top of each spray branch pipe 16 is connected to one end of a connecting pipe 17, and the other end of the connecting pipe 17 is connected to the top of a spray main pipe 13. An opening and closing valve 171 is provided on the connecting pipe 17. When the opening and closing valve 171 is closed, the cooling water can only be sprayed out from the plurality of spiral nozzles 131 on the spray main pipe 13. When the opening and closing valve 171 is opened, the cooling water enters the plurality of spray branch pipes 16, and the cooling water can also be sprayed out from the plurality of spray nozzles 161 on the spray branch pipes 16. Finally, the cooled water after heat exchange becomes hot and enters the circulation water tank 14. The plurality of spiral nozzles 131 and the spray nozzles 161 ensure that the sprayed cooling water can completely cover the surface of the heat exchanger 12. The plurality of spiral nozzles 131 and the spray nozzles 161 spray together, further accelerating the heat exchange efficiency of the heat exchanger 12.

[0036] The above embodiments are only the preferred embodiments of the present invention, which are only used to explain the present invention and do not limit the scope of implementation of the present invention. For those skilled in the art of this technology, of course, other implementation manners can be easily made by means of replacement or change according to the technical content disclosed in this specification.
