[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The utility model discloses a special pump for cooling tower, such as Figure 1-5 As shown, it includes a noise reduction box 1 and a water pump 3 arranged in the noise reduction box 1. The water pump 3 is installed on the cooling tower and is used to extract water from the cooling tower. The interior of the noise reduction box 1 is rotatably connected with a rotating shaft 101 on both sides, and the outer surface of the two rotating shafts 101 is located on one side of the interior of the noise reduction box 1 and is fixedly installed with a sound insulation cover 106. The inner walls of the two sound insulation covers 106 are pasted with sound insulation cotton. When the two sound insulation covers 106 are closed, the sound insulation cotton can effectively suppress the spread of noise.

[0022] The two rotating shafts 101 extend to one end of the outside of the noise reduction box 1 and are fixedly installed with a gear 102. When the gear 102 rotates, it can drive the rotating shaft 101 to rotate. An electric push rod 103 is fixedly installed on one side of the outer surface of the noise reduction box 1, and a connecting rod 104 is fixedly installed on the output end of the electric push rod 103. Racks 105 are fixedly installed at both ends of the connecting rod 104, and the two racks 105 are respectively engaged with the two gears 102. The electric push rod 103 pushes the connecting rod 104 to rise and fall, which will drive the two racks 105 to rise and fall, and then the two gears 102 will rotate in opposite directions. Two shock-absorbing and noise-reduction components are provided inside the noise reduction box 1.

[0023] The shock-absorbing and noise-reducing assembly includes two fixed blocks 301 arranged on the inner bottom surface of the noise reduction box 1 , a slide rod 302 is fixedly connected between the two fixed blocks 301 , and two movable blocks 304 are slidably connected to the outer surface of the slide rod 302 , and the two movable blocks 304 can move along the slide rod 302 .

[0024] Springs 303 are fixedly installed on opposite sides of the two fixed blocks 301 , and the two springs 303 are fixedly connected to the two movable blocks 304 respectively. When the two fixed blocks 301 move away from each other, the two springs 303 are squeezed.

[0025] The top surfaces of the two movable blocks 304 are hinged with connecting arms 305, a support plate 307 is provided inside the noise reduction box 1, and the water pump 3 is placed on the top surface of the support plate 307, the two connecting arms 305 are hinged to the support plate 307, and two dampers 306 are fixedly installed on the inner bottom surface of the noise reduction box 1, and the two dampers 306 are fixedly connected to the support plate 307. When the water pump 3 vibrates during operation, the support plate 307 will drop, and the two connecting arms 305 will push the two movable blocks 304 away from each other and squeeze the spring 303. The elasticity of the spring 303 can reduce the vibration of the water pump 3 during operation, thereby reducing the noise generated by the vibration.

[0026] Two fans 1061 are provided on one side of the interior of the two sound insulation covers 106, and air vents 1062 are provided on one side of the outer surface of the two sound insulation covers 106. When the fans 1061 are running, the external air can enter the closed sound insulation covers 106 through the air vents 1062, so that the air can flow inside the closed sound insulation covers 106 to cool the water pump 3.

[0027] The interior of the two air vents 1062 is rotatably connected to four limit plates 1063, and the interior of the two air vents 1062 is provided with a first filter plate 1064. Four limit holes 1065 are provided on one side of the two first filter plates 1064. The limit plates 1063 are passed through the limit holes 1065 and rotated so that the limit plates 1063 do not overlap with the limit holes 1065. The installation of the first filter plates 1064 can be completed, and the first filter plates 1064 can effectively prevent external dust from entering the closed sound insulation cover 106 with the air.

[0028] The interior of the soundproof cover 106 is equipped with batteries for powering the two fans 1061. The two batteries can serve as the power source for the operation of the fans 1061. The sizes of the four limiting plates 1063 are the same as the sizes of the four limiting holes 1065, and the cross-sections of the four limiting plates 1063 and the four limiting holes 1065 are all rectangular.

[0029] A filter block 2 is provided on one side of the outer surface of the noise reduction box 1, and the filter block 2 is fixedly connected to the water inlet of the water pump 3 through a flange. The interior of the filter block 2 is slidably connected to a movable frame 201, and the interior of the movable frame 201 is detachably connected to a second filter plate 202 by bolts. When external water enters the filter block 2, the second filter plate 202 can filter it to filter impurities in the water to prevent impurities from entering the water pump 3 along with the water. A threaded rod 203 is threadedly connected to one side of the outer surface of the filter block 2, and the end of the threaded rod 203 located inside the movable block is rotatably connected to the movable frame 201. By rotating the threaded rod 203, the movable frame 201 can be pushed to move so as to push the movable frame 201 to the outside of the filter block 2 to disassemble and clean the second filter plate 202. A rubber handle is fixedly installed on the end of the threaded rod 203 away from the movable frame 201.

[0030] The working principle of the present invention is as follows: the electric push rod 103 pushes the connecting rod 104 to move up and down, which can drive the two racks 105 to move up and down. When the two teeth are moved up and down, the two gears 102 can be driven to rotate in opposite directions, so that the two sound insulation covers 106 can be rotated to achieve the closing and unfolding of the two sound insulation covers 106. When the water pump 3 vibrates during operation, the support plate 307 will drop, and the two connecting arms 305 will push the two movable blocks 304 away from each other and squeeze the spring 303. The elasticity of the spring 303 can reduce the vibration of the water pump 3 during operation, thereby reducing the noise generated by the vibration, thereby effectively reducing the impact of the noise generated by the cooling tower special pump on the use environment.
