Description

Technical Field

[0001] The present application relates to the field of wind turbine waterproof detection devices, and in particular to a nozzle position adjustment device. Background Art

[0002] Before leaving the factory, explosion-proof fans need to undergo a series of tests, among which waterproof testing is one of the important testing items. The fan needs to be installed on a fixed mounting frame. The explosion-proof fan will be equipped with openable and closable shutters to close the fan's vents, and the waterproof test is used to test the sealing and waterproof effect of the vents after the shutters are closed.

[0003] During the waterproof test, the edge of the fan louver needs to be sprayed with water through a nozzle. The nozzle is installed on a mechanical arm to control the movement of the nozzle. Under the action of the mechanical arm, the spray trajectory of the nozzle will move with the edge of the fan louver to detect its sealing and waterproof effect. In order to increase the efficiency of fan waterproof testing, several nozzles are often set on the mechanical arm to achieve the effect of testing multiple fans at the same time.

[0004] However, due to the existence of processing errors and installation errors, before conducting the fan waterproofing experiment, the nozzle position needs to be debugged to align it with a specified position of the fan louver. The traditional nozzle installation method, such as using a clamp or other clamp to directly fix the nozzle on the robotic arm, is simple and easy, but lacks flexibility and cannot meet the needs of fine adjustment of the nozzle position and angle.

Detailed Description of the Embodiments

[0039] The following is a further detailed description of the present application in conjunction with the attached Figure 1-7 drawings. Embodiment 1

[0040] This embodiment provides a nozzle position adjusting device, as shown in Figure 1 and Figure 2 , the nozzle position adjusting device includes a mounting frame 1, a first moving seat 11, a second moving seat 12 and a fixture 4.

[0041] The mounting bracket 1 is the support structure of the whole device. The first moving seat 11 is movably arranged on the mounting bracket 1 and can slide or rotate on the mounting bracket 1 to change its position. The second moving seat 12 is movably arranged on the first moving seat 11 and can slide or rotate relative to the first moving seat 11 to achieve multi-angle position adjustment. The clamp 4 is arranged on the second moving seat 12 and is used to fix the nozzle 13. When the second moving seat 12 moves, the clamp 4 and the nozzle 13 thereon will also move accordingly, so as to realize the position adjustment of the nozzle 13.

[0042] The displacement direction of the first moving seat 11 intersects with the moving direction of the second moving seat 12. In this way, through the cooperation of the two, the nozzle 13 can be adjusted in position in multiple directions, improving the flexibility and accuracy of the adjustment, and further realizing the two-dimensional adjustment of the position of the nozzle 13.

[0043] In order to limit the movement of the first moving seat 11, a first limiting device 2 is arranged on the mounting bracket 1, and a second limiting device 21 for limiting the movement of the second moving seat 12 is arranged on the first limiting device 2. When the first moving seat 11 or the second moving seat 12 moves to a predetermined position, it can be fixed by the first limiting device 2 and the second limiting device 21 to prevent its movement.

[0044] In the embodiment of the present application, the first moving seat 11 is slidably arranged on the mounting bracket 1, and the first limiting device 2 includes a first threaded member. The first threaded member is threadedly arranged on the first moving seat 11. By rotating the first threaded member, it can be made to abut against the mounting bracket 1, thereby fixing the first moving seat 11 at a certain position on the mounting bracket 1.

[0045] The second moving seat 12 is arranged on the first moving seat 11 by means of hinge. A connecting rod 15 is hinged on the second moving seat 12. The other end of the connecting rod 15 is hinged with a sliding seat 14. The sliding seat 14 is slidably arranged on the first moving seat 11, and the moving direction of the sliding seat 14 on the first moving seat 11 is parallel to the moving direction of the first moving seat 11 on the mounting bracket 1. A second threaded member is threadedly connected to the sliding seat 14. By rotating the second threaded member, it can be made to abut against the first moving seat 11, thereby fixing the sliding seat 14 at a certain position on the first moving seat 11. When the position of the sliding seat 14 changes, through the transmission of the connecting rod 15, the second moving seat 12 rotates relative to the first moving seat 11 to realize the height adjustment of the nozzle 13.

[0046] To simplify the structure, the first threaded member and the second threaded member are the same threaded member, that is, the first stud 32. One end of the first stud 32 is fixedly connected with a first end plate 3. A first limiting groove 31 is formed in the mounting frame 1 along the moving direction of the first moving seat 11, and the first end plate 3 is clamped in the first limiting groove 31. A long hole 16 is formed in the first moving seat 11, and the length direction of the long hole 16 is parallel to the moving direction of the first moving seat 11 on the mounting frame 1. The first stud 32 passes through the long hole 16, and a first screw sleeve 33 is threadedly connected to one end of the sliding seat 14.

[0047] The operator can drive the first end plate 3 to abut against the inner groove wall of the first limiting groove 31 by tightening the first screw sleeve 33. At the same time, the first screw sleeve 33 abuts against the sliding seat 14. In this way, the first moving seat 11 and the sliding seat 14 are fixed on the mounting frame 1, and the position of the spray head 13 is fixed.

[0048] In this embodiment, the fixture 4 includes a hoop 41 arranged on the second moving seat 12, and the hoop 41 is connected to the second moving seat 12 through a third threaded member 42. The third threaded member 42 can be a screw, a bolt and nut, etc. When it is necessary to fix the spray head 13, the spray head 13 is placed in the hoop 41, and then the third threaded member 42 is rotated to tighten the hoop 41, so as to fix the spray head 13 on the second moving seat 12. Embodiment 2

[0049] As Figure 3 and Figure 4 shown, the difference between the embodiment of the present application and Embodiment 1 is that a spring 34 is sleeved on the first stud 32, and the spring 34 is located between the sliding seat 14 and the first screw sleeve 33. A gasket 36 is sleeved on the first stud 32, and the gasket 36 is located between the sliding seat 14 and the spring 34.

[0050] As Figure 4 and Figure 5 shown, a sleeve 35 is fixedly connected to the gasket 36, and the sleeve 35 is inserted into the spring 34. When the first screw sleeve 33 is tightened, the spring 34 will provide an elastic pre-tightening force, so that the sliding seat 14 and the first moving seat 11 abut against each other, and the first moving seat 11 and the mounting frame 1 abut against each other, which is convenient for the operator to separately adjust the positions of the seat 14 and the first moving seat 11. The operator tightens the first screw sleeve 33, thereby abutting against the sleeve 35, and further fixing both the first moving seat 11 and the sliding seat 14 on the first moving seat 11. Embodiment 3

[0051] As Figure 6 and Figure 7, the difference between the embodiment of the present application and Embodiment 1 is that: the fixture 4 may further include a clamping plate 5. The clamping plate 5 is used to press the nozzle 13 against the second moving seat 12. One end of the clamping plate 5 is provided with a support rod 51, and the support rod 51 is clamped on the second moving seat 12. The other end of the clamping plate 5 is connected to the second moving seat 12 through a locking member 52, thereby fixing the nozzle 13 on the second moving seat 12.

[0052] The locking member 52 includes a rotating seat 57 rotatably connected to the support rod 51. A second stud 54 is disposed through the rotating seat 57. A second end plate 53 is fixedly connected to the second stud 54. The second moving seat 12 is provided with a second limiting groove 55 for the second end plate 53 to be clamped. The second stud 54 passes through the rotating seat 57, and a second nut 56 is threadedly connected to the end of the second stud 54 that passes out of the rotating seat 57. When it is necessary to fix the nozzle 13, place the nozzle 13 between the clamping plate 5 and the second moving seat 12, and then rotate the second nut 56 to tighten the second stud 54, thereby fixing the nozzle 13 on the second moving seat 12.

[0053] The position adjusting device of the nozzle 13 of the present invention realizes the multi-angle position adjustment of the nozzle 13 through the mutual cooperation of the first moving seat 11 and the second moving seat 12. At the same time, through the design of the threaded member and the limiting device, the first moving seat 11 and the second moving seat 12 can be conveniently fixed. It is convenient to adjust the position of the nozzle 13 and improves the stability and accuracy of the adjustment. In addition, the design of the fixture 4 enables the nozzle 13 to be stably fixed on the second moving seat 12, ensuring the spraying effect.

[0054] In practical applications, the device can be improved and optimized according to specific requirements. For example, scales or marks can be added to the mounting frame 1 to more accurately adjust the positions of the first moving seat 11 and the second moving seat 12. In addition, other forms of fixtures 4 or fixing methods can be adopted to adapt to nozzles 13 of different shapes and sizes. In addition, a laser emitting device can also be installed on the second moving seat 12 to facilitate the operator to adjust the position of the nozzle 13.

[0055] To limit the protection scope of the present application accordingly, therefore: all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
