Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically a waterproof and flood-prevention integrated control wind turbine. Background Technology

[0002] In scenarios requiring both ventilation and flood control, such as water conservancy projects, underground buildings, urban utility tunnels, and flood control pumping stations, the stability of the operation of the fan, as a core ventilation device, and its waterproof and flood-proof capabilities directly affect the safety of the scenario.

[0003] According to application number CN202021172443.6, an intelligent control ventilator is disclosed, including a ventilator housing, an exhaust fan is installed inside the ventilator housing and the exhaust fan is connected to the ventilator housing via a support frame, a first limiting block is installed inside the ventilator housing and an activated carbon filter is installed inside the first limiting block, and the first limiting block is located behind the exhaust fan. A second limiting block is installed behind the first limiting block and a HEPA filter is installed inside the second limiting block. A temperature sensor and a humidity sensor are installed on the top of the ventilator housing and a controller is installed behind the temperature sensor. A water tank is installed at the bottom of the ventilator housing.

[0004] The wind turbines in the above cases use a simple grid structure and lack a sealing design. Under severe weather conditions such as heavy rain and floods, rainwater can easily seep into the casing through the ventilation openings, causing short circuits in the drive motor and corrosion of electrical components. This not only causes the wind turbine to malfunction and shut down, but may also pose safety hazards and seriously affect the implementation of flood control emergency work. Moreover, the protective structure of some wind turbines is mostly a manually closed baffle, which cannot be linked with flood control monitoring systems, water level sensors and other equipment. At the same time, it is inconvenient to disassemble and reassemble the wind turbines later, which affects their service life. Therefore, we provide a waterproof and flood control integrated control wind turbine. Summary of the Invention

[0005] The purpose of this utility model is to provide a waterproof and flood-prevention integrated control fan to solve the problems mentioned in the background art.

[0011] Optionally, a fixing groove is provided inside the housing and above the insert block. A movable adjusting block is provided inside the fixing groove. A locking block is installed at the bottom of the adjusting block. A locking slot is provided at the top of the insert block and near the locking block. The bottom of the locking block passes through the top slot and the locking slot from top to bottom and extends into the inside of the locking slot, contacting the inner wall of the locking slot.

[0012] Optionally, a movable block is installed on the top of the adjusting block, and a pull block is installed on the top of the movable block through the fixing groove and extending to its outside. A fastening bolt that is threadedly connected to the housing is provided on the back of the pull block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The drive protection component of this utility model adopts a servo motor to drive the protection plate, which can be directly linked with flood control monitoring system, water level sensor and other equipment to realize full-process joint control of water level exceeding standard, signal triggering and automatic valve closing. No manual intervention is required. It can quickly close the shell opening in case of emergencies such as sudden rainstorms and rising water levels, and cut off the rainwater intrusion path in time.

[0017] 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.

[0018] Please see Figure 1-5 A waterproof and flood-control joint control fan includes a housing 1, a ventilation component 2 on the housing 1, the ventilation component 2 includes an annular frame 21, the annular frame 21 is disposed in the opening of the housing 1, a support frame 22 is installed on the back of the annular frame 21, a drive motor 23 is installed on the front of the support frame 22, a fan 24 is installed on the surface of the output shaft of the drive motor 23, an annular sealing ring 25 is installed on the front of the annular frame 21, and a sealing gasket 26 is installed on the inner wall of the opening on the front of the housing 1.

[0019] The housing 1 is provided with a drive protection component 3, which includes a servo motor 31. The servo motor 31 is installed on the inner wall of the opening of the housing 1. A protective plate 32 adapted to the opening of the housing 1 is installed at the front end of the output shaft of the servo motor 31. The front and back sides of the protective plate 32 are in rotational contact with the inner wall of the housing 1, respectively.

[0020] The housing 1 is provided with a limiting assembly 4, which includes two insert blocks 41, which are respectively installed on the top and bottom of the annular frame 21. A slot 42 is provided on the back of the housing 1 corresponding to the position of the insert blocks 41. The side of the insert block 41 near the slot 42 penetrates the slot 42 and extends into it, contacting the inner wall of the slot 42. A fixing groove 43 is provided inside the housing 1 above the insert blocks 41. A movable adjusting block 44 is provided inside the fixing groove 43. The surface of the adjusting block 44 slides in contact with the inner wall of the fixing groove 43. A clip is installed at the bottom of the adjusting block 44. Block 45 has a slot 46 located near the top of the insert block 41. The bottom of the slot 45 extends from top to bottom through the slot 42 and the slot 46 at the top and into the slot 46, contacting the inner wall of the slot 46. A moving block 47 is installed on the top of the adjusting block 44. A pull block 48 is installed on the top of the moving block 47 through the fixing slot 43 and extending to its outside. The pull block 48 contacts the housing 1 on the side near the housing 1. A fastening bolt 49 threaded to the housing 1 is provided on the back of the pull block 48. Through the positioning and cooperation of the insert block 41 and the slot 42, combined with the fixing structure of the slot 45 and the slot 46, the ventilation component 2 can be quickly disassembled and assembled. During maintenance, only the fastening bolt 49 needs to be loosened and the pull block 48 needs to be pulled to unlock the slot 45. No professional tools or complicated operations are required. One person can complete the inspection and replacement of core components such as the fan 24 and the drive motor 23.

[0021] When the ventilation component 2 needs to be disassembled, first loosen the fastening bolt 49, then pull the pull block 48 upward. The pull block 48 drives the adjusting block 44 upward through the moving block 47, causing the adjusting block 44 to drive the locking block 45 upward. The locking block 45 separates from the slot 46. Then pull the annular frame 21 to the right. The annular frame 21 drives the insert block 41 to move backward, causing the insert block 41 to separate from the slot 42. The annular frame 21 can then be pulled out of the housing 1, making it convenient to maintain and repair the structure on the annular frame 21. After maintenance, align the annular frame 21 with the opening of the housing 1, so that the insert block 41 is inserted into the slot 42. Then press the pull block 48 downward, causing the adjusting block 44 and the locking block 45 to move downward until the locking block 45 passes through the slot 42 and is locked into the slot 46. Finally, tighten the fastening bolt 49 to lock the pull block 48, preventing the components from shifting during equipment operation.

[0022] When in use, the power supply of the drive motor 23 is turned on, and the output shaft of the drive motor 23 drives the fan 24 to rotate. The airflow achieves regional ventilation through the opening of the housing 1. At this time, the servo motor 31 of the drive protection component 3 is in standby mode, and the protection plate 32 remains open, without obstructing the airflow. When the water level sensor of the flood control monitoring system detects that the water level exceeds the standard, the signal is automatically transmitted to the controller of the servo motor 31 to start the flood control protection program. After receiving the signal, the servo motor 31 drives the output shaft to rotate the protective plate 32 until the protective plate 32 is completely attached to the inner wall of the opening of the housing 1 to achieve the opening seal. At this time, the protective plate 32 and the opening are precisely matched. With the double protection of the annular sealing ring 25 and the sealing gasket 26, a sealed space is formed, which completely blocks rainwater and flood from seeping into the interior of the housing 1 through the opening and avoids the drive motor 23 and electrical components from being damaged by moisture. Once the flood warning is lifted and the water level returns to normal, a reset signal is sent via the controller or manual switch, and the servo motor 31 reverses to drive the protective plate 32 to open, allowing the fan to resume normal ventilation.
