Description

Technical Field

[0001] This utility model relates to the field of ventilation system technology, and in particular to a nuclear island wind valve blade drive assembly. Background Technology

[0002] Air valves generally refer to air volume regulating valves, also known as air dampers. They are indispensable central air conditioning terminal accessories in ventilation, air conditioning, and air purification projects in industrial plants and civil buildings. They are generally used in air conditioning and ventilation system ducts to regulate the air volume of branch pipes and can also be used for the mixed regulation of fresh air and return air.

[0003] The utility model disclosed in CN219774819U is a nuclear power plant nuclear island air valve air volume regulating device, including an air valve and a valve plate. A fixing plate is vertically fixedly installed on the top of the air valve, and a scale is engraved on one side of the fixing plate. A fixing block slides on the side of the fixing plate with the scale, and an indicator ball is set above the fixing block. A belt is rotatably installed on one side of the air valve, and there are two belts, both of which are inclined. A connecting mechanism for connecting the valve plate and the indicator ball is provided on one side of the air valve. There are two valve plates, which are rotatably installed at both ends inside the air valve, and through circular grooves are opened at the far ends of the two valve plates.

[0004] In actual use, the valve plate of the above-mentioned device adopts an open-type design, which may generate large eddies and resistance when the airflow passes through the opening. When the wind force is large, the valve stability is poor, and it is difficult to achieve precise and fine adjustment of the opening degree of the valve plate, resulting in insufficient airflow control. To address this, we propose a nuclear island wind valve blade drive assembly. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a nuclear island wind valve blade drive assembly, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nuclear island wind valve blade drive assembly, comprising a frame, wherein a drive mechanism and a cleaning assembly are respectively arranged inside the frame, the drive mechanism includes a first groove and a second groove, both groove one and groove two being formed on the inner wall of the frame, a bidirectional threaded rod is provided inside the upper end of the first groove, the bidirectional threaded rod is rotatably connected to the upper end of the first groove, sliders are provided on both sides of the outer wall of the bidirectional threaded rod, the bidirectional threaded rod and the sliders are threadedly connected, ventilation valve plates are provided on the lower surfaces of the two sliders, the two sliders and ventilation valve plates are fixedly connected, a motor is provided on the outer wall of the frame, and the output end of the motor is fixedly connected to one end of the bidirectional threaded rod:

[0007] The frame is the main body of the device. The frame has two grooves inside. A bidirectional threaded rod is rotatably connected inside the first groove. When the motor is started, the bidirectional threaded rod rotates. The slider drives the ventilation valve to move left and right to open and close. With the cooperation of the above devices, the stability of the ventilation valve can be greatly improved. Compared with the door-type opening method, the blades can effectively avoid the large vortex and resistance that may be generated when the airflow passes through the opening, which makes it difficult to achieve precise and fine adjustment.

[0008] In a preferred embodiment of this utility model, the cleaning assembly includes multiple circular rings, all of which are fixedly connected inside the second groove. One-way shafts are rotatably connected to the outer walls of each of the circular rings, and cleaning rods are rotatably connected between the multiple one-way shafts. The number of cleaning rods is four, and a fan is connected to the outer walls of the multiple frames.

[0009] When the ventilation valve is open, the one-way shaft rotates; when the ventilation valve is closed, the one-way shaft does not rotate. Together with the cleaning rod, the dust on the surface of the ventilation valve is cleaned. The cleaned dust falls into the bottom of the first groove. The fan is started to suck up the dust and discharge it to a designated location for unified treatment, which greatly improves the practicality and convenience of the device.

[0010] The beneficial effects of this utility model are: through the cooperation of the drive mechanism, the stability of the ventilation valve plate can be greatly improved. Compared with the door-type opening method, the blade effectively avoids the large vortex and resistance that may be generated when the airflow passes through the opening, which makes it difficult to achieve precise and fine adjustment.

[0011] This invention utilizes a cleaning component. When the ventilation valve is open, the one-way shaft rotates; when the ventilation valve is closed, the one-way shaft does not rotate. Together with the cleaning rod, the dust on the surface of the ventilation valve is cleaned. Attached Figure Description

A drive mechanism 2 and a cleaning assembly 3 are respectively arranged inside the frame 1. The drive mechanism 2 includes a first groove 202 and a second groove 203, both of which are formed on the inner wall of the frame 1. A bidirectional threaded rod 205 is provided inside the upper end of the first groove 202, rotatably connected to the upper end of the first groove 202. Slider blocks 206 are provided on both sides of the outer wall of the bidirectional threaded rod 205, and the bidirectional threaded rod 205 and the sliders 206 are threadedly connected. Ventilation valve plates 201 are provided on the lower surface of both sliders 206, and both sliders 206 and the ventilation valve plates 201 are fixedly connected. A motor 204 is provided on the outer wall of the frame 1, and the output end of the motor 204 is fixedly connected to one end of the bidirectional threaded rod 205.

[0020] The frame 1 is the main body of the device. The frame 1 has a first groove 202 and a second groove 203. A bidirectional threaded rod 205 is rotatably connected inside the first groove 202. When the motor 204 is started, it drives the bidirectional threaded rod 205 to rotate. The slider 206 drives the ventilation valve 201 to move left and right to open and close. With the cooperation of the above devices, the stability of the ventilation valve 201 can be greatly improved. Compared with the door-type opening method, the blade can effectively avoid the large vortex and resistance that may be generated when the airflow passes through the opening, which makes it difficult to achieve precise and fine adjustment.

The outer walls of the multiple circular rings 301 are rotatably connected to one-way shafts 302, and cleaning rods 303 are rotatably connected between the multiple one-way shafts 302. There are four cleaning rods 303. The outer walls of the multiple frames 1 are connected to fans 304.

[0022] When the ventilation valve 201 is open, the one-way shaft 302 rotates. When the ventilation valve 201 is closed, the one-way shaft 302 does not rotate. Together with the cleaning rod 303, the dust on the surface of the ventilation valve 201 is cleaned. The cleaned dust falls into the bottom of the groove 202. The fan 304 is started to absorb and discharge the dust to a designated location for unified treatment, which greatly improves the practicality and convenience of the device.

[0023] Working principle: The starting motor 204 drives the bidirectional threaded rod 205 to rotate, and the slider 206 drives the ventilation valve 201 to move left and right to open and close. Through the cooperation of the above devices, the stability of the ventilation valve 201 can be greatly improved. When the ventilation valve 201 is open, the one-way shaft 302 rotates. When the ventilation valve 201 is closed, the one-way shaft 302 does not rotate. With the help of the cleaning rod 303, the dust on the surface of the ventilation valve 201 is cleaned. The cleaned dust falls into the bottom of the groove 202. The fan 304 is started to suck up the dust and discharge it to a designated location for unified treatment.
