Description

Technical Field

[0001] The utility model relates to the technical field of spray structures, in particular to a spray structure for a cooling tower for heat dissipation. Background Technique

[0002] A spray cooling tower is an important industrial cooling device, mainly used for reducing the water temperature or treating industrial waste gas. A spray cooling tower is a device that reduces the water temperature by making the sprayed water contact with the air and using evaporation and contact heat transfer. It is widely used in industrial fields such as electric power, metallurgy, chemical industry, refrigeration, etc., for circulating water cooling, waste gas treatment, etc.

[0003] In the spray cooling tower in the prior art, a spray system, a water collector and a guiding air fan are generally arranged in the upper half of the tower. And the height of the whole spray cooling tower is generally relatively high, at least about 3 - 5 meters. And the spray system is arranged at the upper end inside the spray cooling tower. In this way, when the staff needs to detect, repair or replace the nozzles and pipes in the spray structure, it is very troublesome and requires climbing heights. Such operation is inconvenient. Therefore, an improved spray structure for a cooling tower for heat dissipation is needed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spray structure for a cooling tower for heat dissipation, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A spray structure for a cooling tower for heat dissipation, including a cooling tower body. A top cover is arranged at the upper end of the cooling tower body. A transmission mechanism for driving the top cover to rotate is arranged on one side of the surface of the cooling tower body. The transmission mechanism includes a chute, a fixed frame, a rotating block, a worm gear, a motor, and a worm. A chute is fixedly arranged on one side of the surface of the cooling tower body. The upper end inside the chute is movably clamped with a fixed frame. A rotating block is movably arranged inside the fixed frame through a rotating shaft. The upper end of the rotating block is fixedly connected to the top cover. One end of the rotating shaft where the rotating block is located is fixedly provided with a worm gear. A motor is fixedly arranged on the surface of the fixed frame. The output shaft end of the motor is fixedly provided with a worm through a coupling. A spray pipe is arranged inside the top cover.

[0006] Preferably, the worm gear and the worm are meshed with each other. The helix angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm gear. In this way, the worm gear and the worm can be self-locked with each other, that is, only when the worm drives the worm gear to rotate can the worm gear rotate, and the worm gear cannot rotate by itself, so as to ensure the stability of the top cover during use.

[0007] Preferably, a hydraulic cylinder is fixedly arranged at the lower end inside the sliding groove, and the movable end of the hydraulic cylinder is fixedly connected to the fixed frame. The telescopic rod of the hydraulic cylinder can drive the fixed frame to move up and down along the sliding groove.

[0008] Preferably, a notch is formed on one side of the surface of the sliding groove. Through the notch, it is convenient for the fixed frame to drive the motor to move up and down along the sliding groove when moving up and down, thereby preventing movement interference.

[0009] Preferably, a ventilation opening is formed at the lower end of the cooling tower body, and the ventilation opening facilitates the passage of air flow.

[0010] Preferably, a connecting hose is fixed on one side of the surface of the top cover. The connecting hose is fixedly connected to the spray pipe, and the interior of the spray pipe and the connecting hose is mutually communicated. Since the top cover of this device needs to rotate and lift, the pipeline connected to the spray pipe should be made of hose material.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the spray pipe of the present utility model needs to be inspected and repaired, at this time, the motor can be driven to rotate the worm, thereby driving the worm gear to rotate. In this way, the rotating block can be made to rotate around the fixed frame, so that the top cover changes from the Figure 1 state shown to the Figure 2 state shown. Subsequently, the hydraulic cylinder can be contracted, so that the height of the top cover can be reduced. In this way, the top cover rotates and opens, exposing the spray pipe, and at the same time reducing the height of the spray pipe, so that it is convenient to inspect and repair all the components of the spray structure in the upper half of the cooling tower.

[0013] 2. After the top cover of the present utility model is turned over and opened, since the top cover rotates through the worm gear and the worm, the whole rotation and fixing process is convenient. When the worm gear rotates to a suitable angle and the worm does not rotate, self-locking can be formed to fix the angle of the top cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a spray structure for a heat dissipation cooling tower, including a cooling tower body 1, a top cover 2 is arranged at the upper end of the cooling tower body 1, and a transmission mechanism for driving the top cover 2 to rotate is arranged on one side of the surface of the cooling tower body 1. The transmission mechanism includes a sliding groove 3, a fixed frame 4, a rotating block 5, a worm gear 6, a motor 7, and a worm 8. A sliding groove 3 is fixedly arranged on one side of the surface of the cooling tower body 1. A fixed frame 4 is movably clamped at the upper end inside the sliding groove 3. A rotating block 5 is movably arranged inside the fixed frame 4 through a rotating shaft. The upper end of the rotating block 5 is fixedly connected to the top cover 2. One end of the rotating shaft where the rotating block 5 is located is fixedly provided with a worm gear 6. A motor 7 is fixedly arranged on the surface of the fixed frame 4. The output shaft end of the motor 7 is fixedly provided with a worm 8 through a coupling. A spray pipe 13 is arranged inside the top cover 2.

[0021] The worm gear 6 and the worm 8 are meshed with each other. The helix angle of the worm 8 is smaller than the equivalent friction angle between the meshing teeth of the worm 8 and the worm gear 6. In this way, the worm gear 6 and the worm 8 can be self-locked with each other, that is, only when the worm 8 drives the worm gear 6 to rotate can the worm gear 6 rotate, and the worm gear 6 cannot rotate by itself, so as to ensure the stability of the top cover 2 during use;

[0022] A hydraulic cylinder 9 is fixedly arranged at the lower end inside the sliding groove 3. The movable end of the hydraulic cylinder 9 is fixedly connected to the fixed frame 4. The telescopic rod of the hydraulic cylinder 9 can drive the fixed frame 4 to move up and down along the sliding groove 3;

[0023] A notch 10 is opened on one side of the surface of the sliding groove 3. Through the notch 10, it is convenient for the fixed frame 4 to drive the motor 7 to move up and down together when moving up and down along the sliding groove 3, so as to prevent movement interference;

[0024] A ventilation opening 11 is provided at the lower end of the cooling tower body 1, through which air flow can pass conveniently.

[0025] One side of the surface of the top cover 2 is fixedly connected with a connecting hose 12. The connecting hose 12 is fixedly connected with a spray pipe 13. The spray pipe 13 and the inside of the connecting hose 12 are mutually communicated. Since the top cover 2 of this device needs to rotate and lift, the pipes connected to the spray pipe 13 should be made of hose material.

[0026] Working principle: When using this device, when the top cover 2 rotates and covers the upper end of the cooling tower body 1, the top cover 2 and the cooling tower body 1 can form a complete heat dissipation cooling tower; at this time, water flow can be sprayed through the spray pipe 13 for auxiliary heat dissipation, and the whole use process is the same as that of the heat dissipation cooling tower in the prior art; when the spray pipe 13 needs to be inspected and repaired, at this time, the motor 7 can be driven to drive the worm 8 to rotate, so as to drive the worm gear 6 to rotate. In this way, the rotating block 5 can be made to rotate around the fixed frame 4, so that the top cover 2 moves from Figure 1 the state shown to Figure 2 the state shown. Subsequently, the hydraulic cylinder 9 can be contracted, so as to reduce the height of the top cover 2. In this way, the top cover 2 rotates and opens, making the spray pipe 13 exposed, and at the same time reducing the height of the spray pipe 13, so that it is convenient to inspect and repair all the components of the spray structure in the upper half of the cooling tower.

[0027] And when this device is used, after the top cover is turned over and opened or rotated and closed, since the top cover 2 rotates through the worm gear 6 and the worm 8, the whole rotation and fixation process is convenient. After the worm gear 6 rotates to an appropriate angle, the worm 8 does not rotate, then self-locking can be formed to fix the angle of the top cover 2, so that no additional fixing mechanism is needed to fix the top cover 2, thus further facilitating the use of this device.
