Description

Technical Field

[0001] This utility model relates to the field of energy-saving retrofit technology for industrial circulating water cooling towers, specifically a dual-input external water turbine hybrid device for cooling towers. Background Technology

[0002] The common method for powering industrial circulating water cooling tower fans is to use a motor that drives a built-in two-stage reducer via a drive shaft, and the reduced speed then drives the fan. In recent years, another method has emerged that uses a water turbine to utilize the residual pressure of the return water as a power source, driving a built-in two-stage reducer via a drive shaft, and the reduced speed then drives the fan.

[0003] The disadvantages of these two methods:

[0004] 1. The built-in two-stage reducer has a high input speed, generates a lot of heat in the transmission components, and is located inside the air duct, resulting in high maintenance costs;

[0005] 2. Due to the high transmission speed, the dynamic balance requirements for the drive shaft are high, resulting in large vibrations during the transmission process;

[0006] 3. A single power source will affect production when equipment malfunctions and needs repair or replacement. Summary of the Invention

[0007] The purpose of this invention is to provide a dual-input external water turbine hybrid device for cooling towers to solve the problems mentioned in the background art.

The bottom end of the transmission column is provided with a toothed groove in the circumferential direction, and the two toothed discs selectively mesh with the toothed groove.

[0011] In a further embodiment, a speed reducer is connected between the turbine shaft and the corresponding coupling;

[0012] A speed reducer is also connected between the output end of the motor and the corresponding coupling.

[0013] The reducer specifically has an input shaft and an output shaft.

[0014] In a further embodiment, the coupling is provided with a built-in adapter, the built-in adapter having a built-in adapter input shaft and a built-in adapter output shaft.

[0015] In a further embodiment, a hollow seat is fixed to the bottom end of the linkage sleeve, and a second geared disc is rotatably provided at the bottom end of the hollow seat.

[0026] 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.

[0027] This embodiment provides a dual-input external water turbine hybrid device for cooling towers, such as... Figure 1 and Figure 2 As shown, it includes a water turbine 1 and a motor 10. The water turbine 1 has an impeller and a water turbine shaft. The impeller is linked to the water turbine shaft. The output end of the motor 10 is connected to a coupling 9, and the end of the water turbine shaft is connected to a coupling 2.

[0028] The fan 13 has a transmission column 131 and a support base 132. The bottom end of the support base 132 is fixed with a transmission hole for the transmission column 131 to rotate through. A linkage sleeve 15 is horizontally fixed at the bottom end of the support base 132. Both ends of the linkage sleeve 15 are provided with extension sleeves 151. A T-shaped docking shaft 152 is rotatably inserted into the extension sleeve 151. One end of the T-shaped docking shaft 152 extends rotatably into the linkage sleeve 15 and is slidably inserted with a T-shaped transmission rod 154. A gear plate 155 is fixed at the end of the T-shaped transmission rod 154. The end of the T-shaped docking shaft 152 located in the linkage sleeve 15 is connected to a hollow anti-detachment disc 153 to prevent the T-shaped docking shaft 152 from detaching from the extension sleeve 15.

[0029] like Figure 3 , Figure 4 and Figure 5As shown. Couplings, 11 and 14, are connected to the ends of both T-shaped docking shafts 152. Drive shafts 5 and 6 are connected between the couplings at the output end of the motor 10 and the turbine end and the couplings connecting the T-shaped docking shafts 152. A reducer 3 is connected between the turbine shaft and the corresponding coupling 2; the reducer 3 has a reducer input shaft 31 and a reducer output shaft 32. A reducer 8 is also connected between the output end of the motor 10 and the corresponding coupling 9, and the reducer 8 also has a reducer input shaft 81 and a reducer output shaft 82. The couplings are equipped with a built-in adapter 12, which has built-in adapter input shafts 121 and 122 and a built-in adapter output shaft 123.

[0030] At the same time, such as Figure 6 As shown, the bottom end of the transmission column 131 is provided with a toothed groove, and the two toothed discs 155 selectively mesh with the toothed groove. Specifically, a hollow seat 16 is fixed to the bottom end of the linkage sleeve 15, and a toothed disc 163 is rotatably provided at the bottom end of the hollow seat 16. A T-shaped adjusting column 161 is fixed to the upper end of the toothed disc 163. The upper end of the T-shaped adjusting column 161 rotatably extends into the linkage sleeve 15, and the upper end of the T-shaped adjusting column 161 is located between the two toothed discs 155. Two magnet blocks 162 are embedded in the upper end of the T-shaped adjusting column 161, and the magnetic poles of the two magnet blocks 162 on opposite sides are opposite. Magnet blocks 2 are embedded in the opposite side walls of the two toothed discs 155, and the magnetic poles of the two magnet blocks 2 on opposite side walls are opposite. An external shaft is rotatably inserted into the side wall of the hollow seat 16. One end of the external shaft is connected to the output end of an external motor, and the other end extends into the hollow seat to fix a gear disk 164 that meshes with the gear disk 163. The external motor provides power to drive the external shaft to rotate, and the gear disk 164 drives the gear disk 163 to rotate. The T-shaped adjusting column 161 rotates, which can drive the two magnet blocks 162 to rotate through the two gear disks 155. One of the magnet blocks 162 has the same magnetic pole as one of the magnet blocks 2, and the other magnet block 162 has different magnetic poles from one of the magnet blocks 2. In this way, the gear disks 155 at the ends of the two T-shaped transmission rods 154 can be alternately driven to mesh with the tooth grooves of the transmission column 131, so as to alternately provide power to the fan 13. Two magnet blocks 162 and two toothed discs 155 are staggered, with opposite magnetic poles on their opposite sidewalls, generating a magnetic force that attracts each other. This allows both toothed discs 155 to simultaneously mesh with the tooth grooves of the transmission column 131, providing power at the same time.

[0031] In other words, the water turbine 1 and the motor 10 are placed on both sides of the wind tunnel. The water turbine 1 and the motor 10 are each reduced in speed once, and the power is transmitted to the input shaft of the built-in adapter 12 in the wind tunnel by the transmission shaft 6. After Gleason gear coupling and reduction, the output shaft drives the wind turbine to rotate. Alternatively, the coupling on one side can be removed so that the water turbine 1 or the motor 10 can provide power independently.

[0032] When circulating water passes through turbine 1, it drives the impeller of turbine 1 to rotate. The water is input from the reducer input shaft 31 through the turbine shaft and coupling 2. After a first-stage reduction, it is output from the reducer output shaft 32. Then, it is transmitted through coupling 4, transmission shaft 5, and coupling 11 to the built-in adapter input shaft 121 of the built-in adapter 12. After a second reduction through the Gleason gear set, it is output from the output shaft 122, driving the fan 13 to run, thus realizing the single-action of turbine 1.

[0033] When the power of the turbine 1 is insufficient or cannot meet the speed requirements of the fan 13, the motor 10 is started. The power is transmitted to the input shaft 81 of the reducer via the coupling 9. After the first stage of reduction, the power is output from the output shaft 82 of the reducer. Then, it is transmitted to the input shaft 123 of the built-in adapter 12 via the coupling 7, the transmission shaft 6, and the coupling 14. After the second reduction via the Gleason gear set, it is coupled with the power transmitted from the turbine 1 side and output from the output shaft 122 of the built-in adapter, driving the fan 13 to run, thus realizing the hydroelectric hybrid power generation.

[0034] When the power of the turbine 1 and the motor 10 is less than the power required by the fan 13, both must be started simultaneously to supply power to the fan 13 in a mixed manner to meet production needs. When either power source needs maintenance, the fan 13 can also be operated in single-action mode with reduced speed.

[0035] When turbine 1 is under maintenance, coupling 4 can be removed to detach turbine 1, and motor 10 can drive fan 13 to operate independently.

[0036] When motor 10 is not needed or is being repaired, coupling 9 is removed, and turbine 1 operates independently.

[0037] The reducers 3 and 8 used for the primary reduction of the water turbine 1 and the motor 10 can be standardized and mass-produced, which is low in cost and convenient to maintain because they are located outside the wind tunnel.

[0038] The built-in adapter 12 only requires one level of deceleration and has a low transmission speed, which reduces the heat generated by the transmission components, reduces maintenance costs, and can even be made nearly maintenance-free, while greatly extending its service life.

[0039] As the rotational speed decreases, the dynamic balance requirements for drive shafts 5 and 6 are reduced, and the vibration during transmission is also reduced.

[0040] When the power of the turbine and motor is greater than the power required by the fan, a single power source can meet the production needs. By disassembling coupling 2 or coupling 9, the turbine can be switched to single-action mode, allowing for independent maintenance or replacement of turbine 1 or motor 10 without affecting production.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
