Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. It should be noted that, in the absence of conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0018] The blades of the fan blades may be damaged during operation. If these damages cannot be detected and repaired in time, the blades may break, posing a threat to the safety of industrial machines. Manual visual inspection is generally used to inspect the blades, which makes it impossible to detect small cracks, thus creating hidden dangers.

[0019] like Figure 1 As shown, Example 1 of the present application provides a fan blade detection device, including a detection part and a mounting part, the detection part includes an upper plate 22 and a lower plate 21 connected by a base plate 25, a detection area 20 is formed between the upper plate 22 and the lower plate 21, the cross section of the detection area 20 is U-shaped, and the mounting part is connected to the opening of the detection area 20; the mounting part includes a slide 10 and a slider 11 connected to the slide 10, the slider 11 is used to install the fan blade so that the fan blade slides along the slide 10 to the detection part, and the blade of the fan blade is placed in the detection area 20; a number of detection points 201 are respectively provided on the opposite surfaces of the upper plate 22 and the lower plate 21 to detect the blade through the detection points 201; a mounting block 12 is provided on the slider 11, the mounting block 12 and the slider 11 are connected by a rotating shaft, the mounting block 12 is used to fix the axis of the fan blade, and the mounting block 12 is rotated to allow the blade to pass through the detection area 20 in sequence.

[0020] In the embodiment of the present application, to facilitate smooth installation of the fan blade, the slider 11 can be first moved to the right side of the slideway 10 to prevent the detection unit from interfering with the installation of the fan blade. After the fan blade is installed on the mounting block 12, the slider 11 is used to move the fan blade to the left side of the slideway 10 so that the fan blade can extend into the detection area 20 between the upper plate 22 and the lower plate 21. The fan blade is then sequentially detected by the detection points 201 set on the opposing surfaces of the upper plate 22 and the lower plate 21. When rotating the mounting block 12, it can be rotated manually or automatically by an installed motor.

[0021] Specifically, the detection point 201 includes a signal transmitter and a signal receiver. The signal transmitter and the signal receiver are electrically connected to a signal processor respectively. The signal processor is disposed in the base plate 25 .

[0022] Specifically, a display screen 221 is provided on the top of the upper plate 22 . The display screen 221 is electrically connected to the signal processor. The display screen 221 is used to display the detection result of the detection point 201 .

[0023] The signal transmitter generates ultrasonic waves, which contact the surface of the blade. Part of them is absorbed and part of them is reflected back by the blade. The signal receiver receives the reflected ultrasonic waves and converts them into electrical signals and transmits them to the signal processor. The signal processor processes the received ultrasonic signals to determine whether the blade is damaged and displays the results on the display screen 221. The problem of difficult detection of blade damage is solved by ultrasonic waves.

[0024] Specifically, a cylindrical clamping block 13 is positioned at the center of mounting block 12. The diameter of clamping block 13 matches the diameter of the blade's central hole, allowing it to snap into place within the central hole and secure the blade and clamping block 13. A rubber layer 14 is sleeved over clamping block 13, with the thickness of rubber layer 14 gradually decreasing toward the top of clamping block 13. By providing clamping block 13 to secure the blade, the present embodiment can replace clamping blocks 13 of varying diameters, allowing installation and testing of blades of varying sizes, thereby improving the applicability of the blade detection device.

[0025] Specifically, magnets are provided at both ends of the slide 10. When installing the fan blade, to prevent the slider 11 from sliding in the slide 10, a magnet is provided on the side of the slide 10 away from the detection area 20. The slider 11 is fixed by attracting the magnet, and when the fan blade is driven to slide to the left side near the detection part, the slider 11 is prevented from sliding in the slide 10 when the fan blade is being tested. In this application, a magnet is provided at one end of the slide 10 near the detection area 20 to fix the slider 11 on the side of the slide 10 near the detection area 20.

[0026] Specifically, the bottom plate 25 and the upper plate 22 are integrally formed. A vertically extending slide bar 23 is provided on the lower plate 21 relative to the bottom plate 25. The slide bar 23 penetrates the bottom plate 25, and the bottom plate 25 drives the upper plate 22 to slide up and down along the slide bar 23. A knob 24 is provided on the bottom plate 25, which penetrates the bottom plate 25 and connects to the slide bar 23 to secure the bottom plate 25 and the slide bar 23. By adjusting the angle of the knob 24, the bottom plate 25 can be fixed to the slide bar 23 or slide relative to the slide bar 23. The bottom plate 25 drives the upper plate 22 to slide upward along the slide bar 23, thereby changing the size of the detection area 20 to accommodate different fan blades.

[0027] For example, Figure 1 As shown, in the embodiment of the present application, the extension direction of the slideway 10 is consistent with the extension direction of the detection area 20.

[0028] The blade detection device provided in the embodiment of the present application detects the blades of the blades of the blades. Figure 1As shown, first, the slider 11 is moved to the right side of the slide 10, the fan blade is installed on the mounting block 12, then the fan blade is moved to the left side of the slide 10 through the slider 11, so that the blade of the fan blade can extend into the detection area 20 between the upper plate 22 and the lower plate 21, the detection points 201 arranged on the opposite surfaces of the upper plate 22 and the lower plate 21 detect the blade of the fan blade in turn, after the detection is completed, the slider 11 is moved back to the right side of the slide 10, and the fan blade is removed to complete the detection.

[0029] In conclusion, the fan blade to be detected is installed on the mounting block from the mounting part, moved to the detection part along the slide, the blade of the fan blade is detected in turn by rotating the mounting block and passing through the detection area formed between the upper plate and the lower plate, a plurality of detection points are arranged on the opposite surfaces of the upper plate and the lower plate respectively, the blade is detected by the plurality of detection points, which can make the detection more accurate and comprehensive, and the detection points are distributed along the extension direction of the blade, which can detect the blade at the same time, without moving the fan blade and the detection equipment after one detection, only rotating the mounting block can detect the blade in turn, reducing the detection steps and improving the detection efficiency; the detection point 201 includes a signal transmitter and a signal receiver, the signal transmitter generates ultrasonic waves, contacts the surface of the blade, the signal receiver receives the reflected ultrasonic waves and converts them into electrical signals transmitted to the signal processor, the signal processor processes the received ultrasonic signals to obtain the result of whether the blade is damaged, and displays the result on the display screen 221, and the problem of difficult detection of blade damage is solved by ultrasonic waves.
