Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower ventilation, in particular to a cooling tower ventilation device. 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 principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate excess heat generated in industry or refrigeration and air conditioning to lower the water temperature by using water as a circulating coolant and dissipating it into the atmosphere to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] To ensure heat dissipation, existing cooling towers are usually equipped with ventilation devices to ventilate and introduce outside air into the cooling tower. For example, Chinese Patent Publication No. CN209892481 U discloses a "Cooling Tower Ventilation Device" which, by providing a movable frame, allows users to easily disassemble and install the air duct, thus facilitating maintenance and cleaning of the air duct. The structure of the baffle and the air duct facilitates dust protection of the air duct, preventing external dust from entering the interior of the air duct and causing blockage. The structure of the drive wheel and transmission belt increases the stability of the connection between the two, while also improving the driving efficiency of the motor.

[0004] However, in actual use, the cooling tower needs to be shut down when the air duct is disassembled for maintenance and cleaning to avoid affecting the disassembly and assembly. The cooling tower itself has a large ventilation volume when working, which can easily suck external debris into the cooling tower and affect the operation of the cooling tower. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art that the use of the cooling tower is affected when the air duct is maintained and cleaned, and the external debris is easily sucked into the cooling tower when the cooling tower is working, thereby affecting the operation of the cooling tower. A cooling tower ventilation device is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A cooling tower ventilation device is designed, comprising a vent provided on the cooling tower, a bracket provided in the vent, a fan provided in the bracket, a first motor connected to the fan power fixedly provided on the bracket, and a protective structure provided on the vent;

[0008] The protective structure includes a protective cover and a filter screen. The protective cover is provided with a through slot and is fixedly arranged on the vent. The filter screen is fixedly arranged in the protective cover. A cleaning mechanism is provided between the protective cover and the filter screen.

[0009] Furthermore, the cleaning mechanism includes a brush, the protective cover is provided with a guide rail that cooperates with the brush, and the brush is provided with a driving structure that cooperates with the guide rail.

[0010] Furthermore, a guide portion is fixedly provided on the brush, and an annular groove matching the guide portion is provided on the protective cover.

[0011] Furthermore, the driving structure includes a mounting seat, which is slidably connected to the guide rail. A gear ring is fixedly provided at the lower end of the guide rail, and a transmission groove that cooperates with the gear ring is opened on the mounting seat.

[0012] Furthermore, a second motor is fixedly installed in the mounting seat, and an output shaft of the second motor is fixedly connected to a transmission part meshing with the gear ring.

[0013] Furthermore, an annular guide portion is fixedly provided on the inner wall of the protective cover, and the inner wall of the guide portion is fixedly connected to the filter screen.

[0014] The cooling tower ventilation device proposed in this utility model has the following beneficial effects:

[0015] In the present invention, a protective cover is used to prevent large debris from entering the cooling tower, a filter is provided to prevent flying insects from being sucked into the cooling tower, and a cleaning mechanism is provided to clean the filter to prevent the filter from being blocked.

[0016] Secondly, in the present invention, the second motor cooperates with the gear ring to drive the mounting seat and the brush to move, thereby cleaning the filter screen, and the cleaned dust is discharged along the through slot of the protective cover through the guide part to avoid dust accumulation and blockage.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The protective structure 6 includes a protective cover 61 and a filter 62 . The protective cover 61 is provided with a through slot and is fixedly mounted on the vent 2 . The filter 62 is fixedly mounted inside the protective cover 61 . A cleaning mechanism 7 is provided between the protective cover 61 and the filter 62 .

[0026] In the present invention, a protective cover 61 is used to prevent large debris such as flying birds from entering the cooling tower 1, a filter screen 62 is provided to prevent small debris such as flying insects from entering the cooling tower 1, and a cleaning mechanism 7 is provided to clean the filter screen 62 to prevent the filter screen 62 from being blocked. The cleaning mechanism 7 can be connected to an external control module to clean the filter screen 62 regularly.

[0027] Furthermore, in this embodiment, the cleaning mechanism 7 includes a brush 71, a guide rail 72 that cooperates with the brush 71 is provided on the protective cover 61, and a driving structure 73 that cooperates with the guide rail 72 is provided on the brush 71. Under the action of the driving structure 73, the brush 71 rotates around the filter 62 along the annular guide rail 72 to clean the filter 62.

[0028] Furthermore, in this embodiment, a guide portion 711 is fixedly provided on the brush 71, and an annular groove 74 cooperating with the guide portion 711 is provided on the protective cover 61. The annular groove 74 cooperates with the guide portion 711 to share the weight of the brush 71, thereby preventing the driving structure 73 from being overloaded.

[0029] It should be noted that, in this embodiment, the driving structure 73 includes a mounting seat 731, which is slidably connected to the guide rail 72. A gear ring 732 is fixedly provided at the lower end of the guide rail 72. A transmission groove that cooperates with the gear ring 732 is provided on the mounting seat 731.
