[0024] 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.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a permanent magnet constant pressure energy-saving fan, including a support mechanism 1, two guide rail assemblies 1011 are fixedly connected to each other on the outer side of the support mechanism 1, the guide rail assembly 1011 has a longitudinal groove inside, and the two guide rail assemblies 1011 are respectively slidably connected to a moving mechanism 3 and a sliding assembly 3013.

[0026] Both the moving mechanism 3 and the sliding component 3013 have screw holes inside and are screwed with fixing bolts 301. The front cover 3011 is bolted to the rear side of the moving mechanism 3. The rear cover 3014 is bolted to the interior of the sliding component 3013. The top surfaces of the rear cover 3014 and the front cover 3011 are fixedly connected with discharge pipes 3012. The two discharge pipes 3012 are respectively connected to the front cover 3011 and the rear cover 3014. The rear side of the rear cover 3014 is equipped with a baffle assembly 3015. The cross-section of the baffle assembly 3015 is circular. The front end of the baffle assembly 3015 is fixedly connected with a column assembly 3016 in a ring array. The main body of the column assembly 3016 is cylindrical. The rear side of the baffle assembly 3015 is equipped with a permanent magnet motor 3017. The front end of the permanent magnet motor 3017 is provided with an output shaft.

[0027] Through the cooperation of support mechanism 1, guide rail assembly 1011, moving mechanism 3, sliding assembly 3013, fixing bolt 301, front cover 3011, rear cover 3014, discharge pipe 3012, baffle assembly 3015, insert column assembly 3016 and permanent magnet motor 3017, the sliding connection and assembly of various components of the fan can be realized, which facilitates the installation and disassembly of some components of the fan without relying on external hoisting equipment, thus solving the limitations of existing fan assembly and disassembly.

[0028] See Figure 1 , Figure 5 The support mechanism 1 has two assembly holes 101 inside, which are located on the left and right sides inside the support mechanism 1.

[0029] The two mounting holes 101 opened through the support mechanism 1 are located on the left and right sides inside the support mechanism 1, providing installation positions for connecting the fan to other equipment, thereby enhancing the stability and convenience of fan installation.

[0030] See Figure 3 , Figure 4 A servo motor 1012 is mounted on the front end of the guide rail assembly 1011 located on the front side, and a transmission assembly 1013 is mounted on the rear output shaft of the servo motor 1012.

[0031] By providing power for the moving mechanism 3 and the sliding component 3013 to slide within the guide rail assembly 1011 through the servo motor 1012 at the front end of the front guide rail assembly 1011 and the transmission assembly 1013 on the rear output shaft, the position of the components can be automatically adjusted.

[0032] See Figure 1 , Figure 2The transmission component 1013 is a lead screw structure and is rotatably connected to the guide rail component 1011 through a bearing seat. The top surface of the support mechanism 1 is fixedly connected to the lifting mechanism 2.

[0033] The transmission assembly 1013, which is equipped with a lead screw structure, is rotatably connected to the guide rail assembly 1011 through the bearing seat. In conjunction with the servo motor 1012, the movement of the moving mechanism 3 and the sliding assembly 3013 can be precisely controlled. The lifting mechanism 2 at the top of the support mechanism 1 is used to support and fix the subsequent components, thereby enhancing the structural stability of the fan.

[0034] See Figure 5 , Figure 6 The top surface of the lifting mechanism 2 is perpendicularly connected to the top surface of the support mechanism 1. The top surface of the lifting mechanism 2 is fixedly connected to the support frame 201, which is a circular structure.

[0035] By setting up a lifting mechanism 2 that is vertically connected to the top surface of the support mechanism 1, the circular support frame 201 at the top provides a stable support platform for the installation of subsequent components, ensuring the overall structural stability of the fan and making the fan run more smoothly.

[0036] See Figure 1 , Figure 2 There are two support frames 201, which are fixedly connected in a straight line array to the front and rear sides of the top surface of the lifting mechanism 2.

[0037] By setting up two support frames 201 fixed in a linear array on the top surface of the lifting mechanism 2, the support capacity for subsequent components is further enhanced, the overall structural layout of the wind turbine is optimized, and the stability and reliability of the wind turbine are improved.

[0038] See Figure 3 , Figure 6 The inner sides of the two lifting mechanisms 2 are fixedly connected to two side plate assemblies 2011 and a retainer 2012 facing each other. The retainer 2012 has a bearing seat installed inside, and the fan blade unit 2013 is assembled through the bearing seat. The rear side of the fan blade unit 2013 has an assembly slot that matches the front output shaft of the permanent magnet motor 3017.

[0039] The side plate assembly 2011, the retainer 2012, and the fan blade unit 2013, which are equipped with two supporting mechanisms 2, work together. The bearing seat inside the retainer 2012 is equipped with the fan blade unit 2013. The rear side of the fan blade unit 2013 is matched with the front output shaft of the permanent magnet motor 3017, ensuring that the permanent magnet motor 3017 can drive the fan blade unit 2013 to rotate, thereby realizing the ventilation function of the fan.

[0040] During operation, firstly, the fan is installed on the corresponding equipment through the assembly hole 101 of the support mechanism 1. The support mechanism 1 provides a stable foundation support for the entire fan.

[0041] The servo motor 1012 located at the front end of the front guide rail assembly 1011 starts, and its output shaft drives the transmission assembly 1013 to rotate. Since the transmission assembly 1013 is a lead screw structure and is rotatably connected to the guide rail assembly 1011 through a bearing seat, when the transmission assembly 1013 rotates, it can push the moving mechanism 3 and the sliding assembly 3013 to slide in the longitudinal groove of the guide rail assembly 1011. The moving mechanism 3 and the sliding assembly 3013 are both provided with screw holes. By screwing in the fixing bolt 301, the front cover 3011 and the rear cover 3014 can be fixed respectively. When the moving mechanism 3 and the sliding assembly 3013 slide, since the moving mechanism 3 and the sliding assembly 3013 are both provided with screw holes that match the transmission assembly 1013, the front cover 3011 and the rear cover 3014 can be driven to move inward synchronously, which facilitates the installation, disassembly and maintenance of the internal components of the fan.

[0042] The lifting mechanism 2 is vertically fixed to the top surface of the support mechanism 1. Two circular support frames 201 at its top provide stable support for subsequent components. The side plate assembly 2011 and the retainer 2012 are connected to each other on the inner side of the two lifting mechanisms 2. The retainer 2012 has a bearing seat installed inside. The fan blade unit 2013 is assembled in the retainer 2012 through the bearing seat. The permanent magnet motor 3017 is installed on the rear side of the baffle assembly 3015. Its front output shaft matches the assembly slot opened on the rear side of the fan blade unit 2013. After the permanent magnet motor 3017 is started, the output shaft drives the fan blade unit 2013 to rotate at high speed.

[0043] During the rotation of the fan blade unit 2013, air enters from the front end of the front cover 3011 and the rear cover 3014. After being accelerated by the fan blade unit 2013, it becomes a high-speed airflow. The high-speed airflow is discharged through the exhaust pipe 3012 at the top of the front cover 3011 and the rear cover 3014, thus achieving the ventilation function. The insert components 3016 on the baffle assembly 3015 are arranged in a ring array. Their cylindrical structure not only plays a certain role in turbulence, allowing the incoming air to flow more evenly to the fan blade unit 2013, but also prevents foreign objects from entering the fan to a certain extent, protecting the internal components of the fan.

[0044] In summary, this device, equipped with a fan blade unit 2013, can achieve rapid ventilation.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
