Description

Technical Field

[0001] This invention relates to the field of speed-regulating fan technology, specifically an integrated skid-mounted permanent magnet flexible non-contact energy-saving speed-regulating fan system. Background Technology

[0002] The skid-mounted integrated permanent magnet speed-regulating fan is a highly efficient, energy-saving, and ready-to-use intelligent regulating fan system that uses permanent magnet speed regulation technology as the core drive method and integrates it with the fan, motor, and control system on the same skid-mounted base.

[0003] In cooling and ventilation scenarios for industrial permanent magnet rotors, if the fan directly vents air, it may result in excessively strong local winds and insufficient winds in the surrounding areas. Existing technologies struggle to ensure that the airflow evenly covers the permanent magnet rotor space, thus failing to improve the uniformity of the cooling effect and limiting their practicality. Furthermore, existing technologies suffer from poor rotor integration, mechanical direction adjustment, and air-to-ground transmission during use.

The embodiments of this invention will now be described according to its overall structure.

[0019] Example 1: Please see Figures 1-3 The present invention discloses an integrated skid-mounted permanent magnet flexible non-contact energy-saving speed-regulating fan system, comprising a base 1, a first motor 2 fixedly connected to the bottom of the base 1, the first motor 2 being electrically connected to a permanent magnet controller 3 via a cable, a conductor rotor 4 being provided on the outer wall of the first motor 2, a permanent magnet rotor 5 being provided at the right end of the conductor rotor 4, the output shaft at the right end of the first motor 2 being connected to the fan body 6, a detection mechanism 7 being provided at the upper part of the fan body 6, a shielding mechanism 8 being provided at the rear end of the top of the fan body 6, and an adjustment component 9 being provided at the front side of the base 1.

[0020] The adjusting component 9 includes a first fixing plate 91. The first fixing plate 91 is fixedly connected to the left side of the front side of the base 1. The fourth motor 92 is fixedly connected to the left end of the first fixing plate 91. The first fixing plate 91 facilitates the installation and fixing of the fourth motor 92.

[0021] The right output shaft of the fourth motor 92 is fixedly connected to a lead screw 93. The right end of the lead screw 93 is rotatably connected to the left end of the second fixed plate 94, so that the fourth motor 92 can easily drive the lead screw 93 to rotate.

[0022] An electromagnetic brake 95 is sleeved on the right end of the outer wall of the lead screw 93. A timer 96 is fixedly connected to the right end of the second fixing plate 94. A mounting shell 97 is fixedly connected to the right side of the front end of the base 1. A connecting shell 98 is fixedly connected to the bottom inside the mounting shell 97. A motor 99 is fixedly connected to the left end inside the connecting shell 98. The connecting shell 98 facilitates the installation and fixing of the motor 99.

[0023] The right output shaft of the motor 99 is fixedly connected to a rotating disk 910. The right end of the rotating disk 910 is eccentrically provided with a first protruding rod 911. The outer wall of the first protruding rod 911 is slidably connected to a sliding groove swing rod 912. The upper inner part of the sliding groove swing rod 912 is slidably connected to the outer wall of the second protruding rod 913. The rotating disk 910 can easily drive the first protruding rod 911 to make circular motion.

[0024] The left end of the second protruding rod 913 is fixedly connected to a sliding extrusion plate 914. The rear end of the mounting shell 97 is fixedly connected to a control switch 915. The control switch 915 is electrically connected to the timer 96. The lower left end of the sliding swing rod 912 is rotatably connected to the lower right end of the connecting shell 98. The bottom of the sliding extrusion plate 914 is slidably connected to the top of the connecting shell 98.

[0025] The front end of the second fixing plate 94 is fixedly connected to the right end of the front side of the base 1, and the lead screw 93 passes through the conductor rotor 4 and the permanent magnet rotor 5 and is connected to their internal threads.

[0026] The working principle of the integrated skid-mounted permanent magnet flexible non-contact energy-saving speed-regulating fan system based on Embodiment 1 is as follows: When using this device, first place it in the work area, then connect it to an external power source to provide the power required for its operation. When the first motor 2 drives the conductor rotor 4 to rotate, the rotating permanent magnetic field cuts the magnetic field lines in the conductor disk, generating a strong eddy current. This eddy current induces a magnetic field that interacts with the permanent magnetic field, thus "dragging" the permanent magnet rotor 5 to rotate synchronously and drive the fan body 6. When the magnetic coupling effect weakens, the transmitted torque decreases and the speed of the fan body 6 decreases. When the magnetic coupling effect strengthens, the transmitted torque increases and the speed of the fan body 6 increases until it approaches the speed of the first motor 2. At the same time, the fourth motor 92 is started. The fourth motor 92 drives the lead screw 93 to rotate. Multiple micro harmonic reducers are used in conjunction with the circumferentially distributed lead screw 93 push rods to push the permanent magnet rotor 5 from multiple points simultaneously and synchronously, ensuring that it is absolutely parallel during movement and avoiding any local friction or performance loss caused by tilting. When the fourth motor 92 drives the lead screw 93 to stop working, the electromagnetic brake 95 is activated, directly locking the lead screw 93 and preventing it from rotating, thereby indirectly preventing the movement of the permanent magnet rotor 5. When the fourth motor 92 drives the lead screw 93 to rotate, the motor 99 is activated, which drives the rotating disk 910 to rotate. The rotating disk 910 drives the first protrusion 911 to perform circular motion, which in turn drives the sliding groove swing rod 912 to swing backward. The sliding groove swing rod 912 drives the sliding extrusion plate 914 to move backward at the top of the connecting shell 98 via the second protrusion 913, causing the extrusion plate 914 to press against the control switch 915. The control switch 915 then activates the timer 96, which records the working time of the motor 99. The performance degradation curve of the lead screw 93 is analyzed using external equipment to provide data support for subsequent work.

[0027] Example 2: Please see Figures 4-6 The present invention provides an integrated skid-mounted permanent magnet flexible non-contact energy-saving speed-regulating fan system. Compared with Embodiment 1, this embodiment further includes: an air outlet 7, which includes an air outlet 71. An air outlet 71 is provided on the upper part of the fan body 6. Eight sets of air outlet plates 72 are fixedly connected inside the air outlet 71. A flow guiding mechanism 73 is fixedly connected to the upper right end of the fan body 6.

[0028] The flow guiding mechanism 73 includes a first mounting box 731. The first mounting box 731 is fixedly connected to the upper right end of the fan body 6. A flow guiding plate 732 is provided at the left end of the first mounting box 731. An mounting plate 733 is fixedly connected to the rear end of the first mounting box 731. The first mounting box 731 facilitates the installation and fixing of the mounting plate 733.

[0029] A second motor 734 is fixedly connected to the upper left end of the mounting plate 733. A first rotating rod 735 is fixedly connected to the output shaft at the right end of the second motor 734. A slider 736 is rotatably connected to the lower right end of the first rotating rod 735. The slider 736 is slidably connected to the outer wall of the swing rod 737, and the slider 736 facilitates the swinging of the swing rod 737.

[0030] A mounting rod 738 is fixedly connected to the lower left end of the swing rod 737. A laser rangefinder 739 is fixedly connected to the front end of the first mounting box 731. A guide plate 732 is fixedly connected to the left end of the mounting rod 738. The guide plate 732 facilitates the airflow to cover the space of the permanent magnet rotor 5 more evenly.

[0031] The mounting rod 738 passes through the mounting plate 733, the first mounting box 731 and the fan body 6 and is rotatably connected to them. The lower right end of the mounting plate 733 is rotatably connected to the swing rod 737. The laser rangefinder 739 is electrically connected to the external display screen.

[0032] In this embodiment: During operation, the fan body 6 discharges air through the air outlet 71, and then disperses the gas through the air outlet plate 72 to improve gas dispersion. When the guide plate 732 needs to be adjusted, the second motor 734 is started. The second motor 734 drives the first rotating rod 735 to rotate. The first rotating rod 735 drives the slider 736 to slide on the outer wall of the swing rod 737, and simultaneously drives the swing rod 737 to swing. The swing rod 737 drives the mounting rod 738 to rotate, and the mounting rod 738 drives the guide plate 732 to rotate. By adjusting the guide plate 732, the airflow can be more evenly covered in the space of the permanent magnet rotor 5, improving the uniformity of the cooling effect. During the swing of the swing rod 737, the position is detected by the laser rangefinder 739, and the electrical signal is transmitted to the external display screen. The adjustment angle of the guide plate 732 is indirectly determined by the distance information on the external display screen.

[0033] Example 3: Please see Figure 7 The present invention provides an integrated skid-mounted permanent magnet flexible non-contact energy-saving speed-regulating fan system. Compared with Embodiment 1, this embodiment further includes: a shielding mechanism 8, which includes a baffle 81. The baffle 81 is provided at the top rear end of the fan body 6. A second mounting box 82 is fixedly connected to the top front end of the fan body 6. A connecting rod 83 is fixedly connected to the bottom rear end of the second mounting box 82. The second mounting box 82 facilitates the installation and fixing of the connecting rod 83.

[0034] A base plate 84 is fixedly connected to the top of the connecting rod 83. A third motor 85 is fixedly connected to the front end of the bottom of the base plate 84. A swing block 86 is fixedly connected to the top output shaft of the third motor 85. A second rotating rod 87 is rotatably connected to the rear end of the swing block 86. The third motor 85 can easily drive the swing block 86 to rotate.

[0035] The rear end of the outer wall of the second rotating rod 87 is rotatably connected to a moving rod 88. The moving rod 88 passes through the limiting block 89 and is slidably connected to its interior. The bottom of the limiting block 89 is fixedly connected to the rear end of the top of the base plate 84. The front end of the baffle 81 is provided with an insertion hole, and the moving rod 88 is inserted and fixedly connected to the insertion hole.

[0036] The cooperative relationship between the adjusting component 9 and the blocking mechanism 8 Both work together to ensure stable wind pressure in the wind turbine system under varying operating conditions, improving system reliability and energy efficiency. The following aspects are addressed: Dynamic response coordination: When the system detects a change in air pressure, for example, due to changes in external pipeline resistance or user demand, the regulating component 9 acts first: by adjusting the position of the permanent magnet rotor to change the fan speed, thereby quickly correcting the air pressure. If the air pressure is still unstable or fluctuates after the speed adjustment, the blocking mechanism 8 then intervenes: by adjusting the opening of the baffle 81 to limit or release the air volume, it plays a buffering role and prevents pressure overshoot or drop.

[0037] Preventative coordination: During fan start-up or shutdown, the regulating component 9 may not be able to reach the target speed instantly. In this case, the blocking mechanism 8 can reduce its opening in advance to limit the initial airflow and avoid sudden pressure changes. Similarly, when the regulating component 9 makes a large-range speed adjustment, the blocking mechanism 8 can act synchronously to smoothly transition the airflow change.

[0038] Furthermore, components such as the timer 96 and motor 99 in the regulating component 9 can record the performance data of the lead screw 93, providing long-term operational trend analysis for the system. This data can be used to optimize the control strategy of the shielding mechanism 8, for example, predicting pressure fluctuation points and adjusting the baffle position in advance. The two are linked through a central controller to form a closed-loop control: the sensor monitors the wind pressure in real time, and the controller simultaneously outputs signals to the regulating component 9 and the shielding mechanism 8, achieving precise coordination.

[0039] In this embodiment: After the dust on the blower body 6 is blown away by external equipment, the staff covers the air outlet of the blower body 6 with the baffle 81, and then starts the third motor 85. The third motor 85 drives the swing block 86 to rotate. The swing block 86 drives the moving rod 88 to move backward within the limit block 89 through the rotational connection with the second rotating rod 87, so that the moving rod 88 is inserted into the front hole of the baffle 81 to achieve insertion and fixation. This installs and fixes the baffle 81, preventing dust and moisture in the environment from entering the interior of the blower body 6 and extending the service life of the blower body 6.

[0040] This invention provides an improved integrated skid-mounted permanent magnet flexible non-contact energy-saving speed-regulating fan system. It features an adjusting component 9, employing multiple micro-harmonic reducers and circumferentially distributed lead screws 93 to simultaneously and synchronously push the permanent magnet rotor 5 from multiple points, ensuring absolute parallelism during movement and avoiding any tilting that could cause localized friction or performance loss. An electromagnetic brake 95 indirectly prevents the permanent magnet rotor 5 from moving. Finally, a timer 96 records the operating time of the motor 99, and the performance degradation curve of the lead screw 93 is analyzed to provide data support for subsequent work. A flow guiding mechanism 73 is included, which adjusts the guide plate 732 to ensure more even airflow coverage of the permanent magnet rotor 5, improving the uniformity of cooling. A shielding mechanism 8 is also included, which covers the air outlet of the fan body 6 with a baffle 81 to prevent dust and moisture from entering the fan body 6, extending its service life.
