[0023] To further explain the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components

[0024] As Figure 1 shown, this embodiment provides an installation and maintenance training device for water turbine power generation equipment, including a support frame 1, an XY azimuth reference line suspension bracket 2, a center template 3, a simulated foundation embedment plate 4, an elevation adjustment wedge plate 5, a simulated foundation mother plate 6, simulated anchor bolts 7, a simulated base plate 8, and an XY azimuth adjustment line suspension bracket 9

[0025] The support frame 1 is fixed in the training room through the frame foundation bolts 15. The center template 3 is fixedly installed at the center of the bottom of the support frame 1 and serves as the central reference of the device. There is a concave pit at the center of the center template 3, and the depth of the concave pit at the center of the center template 3 is 1 mm. The center point of the center template 3 is marked with a cross line. The simulated foundation embedded plate 4 is fixedly installed on the top of the support frame 1 as the training platform, and the X azimuth line 41, Y azimuth line 42 and elevation sample points 10 are provided on the surface. The X azimuth line 41 and Y azimuth line 42 serve as the azimuth reference of the device. The XY azimuth reference line suspension bracket 2 is installed in the middle of the support frame 1 to suspend the X azimuth reference line and Y azimuth reference line. The XY azimuth reference line suspension bracket 2 is a rectangular bracket arranged around the middle of the support frame 1. The X azimuth reference line and Y azimuth reference line suspended on the XY azimuth reference line suspension bracket 2 are based on the X azimuth line 41 and Y azimuth line 42 as the azimuth reference.

[0026] Through holes are opened at the centers of the simulated foundation embedded plate 4, simulated foundation mother plate 6 and simulated foundation plate 8. The simulated foundation mother plate 6 is connected to the surface of the simulated foundation embedded plate 4 through simulated anchor bolts 7. The elevation adjustment wedge plate 5 is arranged between the simulated foundation mother plate 6 and the simulated foundation embedded plate 4 to adjust the elevation of the simulated foundation mother plate 6. A pair of elevation adjustment wedge plates 5 are respectively arranged on the X positive azimuth, X negative azimuth along the X azimuth line 41 and the Y positive azimuth, Y negative azimuth along the Y azimuth line 42 of the simulated foundation embedded plate 4, that is, a total of 8 elevation adjustment wedge plates 5. Each elevation adjustment wedge plate 5 includes a first wedge plate and a second wedge plate stacked in a form with the slopes facing each other in the reverse direction. As Figure 1 shown, the slopes of the first wedge plate and the second wedge plate facing each other in the reverse direction means that the slopes of the first wedge plate and the second wedge plate are in contact with each other, and at the same time, the extending direction of the slope foot of the first wedge plate is opposite to the extending direction of the slope foot of the second wedge plate. The simulated foundation plate 8 is connected to the surface of the simulated foundation mother plate 6 through bolt fastening. By adjusting the simulated foundation mother plate 6, the adjustment of the simulated foundation plate 8 is indirectly realized.

[0027] By tightening or loosening the 8 elevation adjustment wedge plates 5, the elevation of the simulated foundation plate 8 is adjusted. After the elevation is adjusted, a feeler gauge is used to check the gaps between the lower plane of the simulated foundation mother plate 6 and the first wedge plate, between the first wedge plate and the second wedge plate, and between the second wedge plate and the upper plane of the simulated foundation embedded plate 4, so as to realize the training of elevation and gap measurement.

[0028] After the various data of the simulated foundation plate 8 are adjusted to be qualified, the simulated on-site working process is simulated, and the simulated anchor bolts 7 are tightened to fix the simulated foundation mother plate 6 and the simulated foundation embedded plate 4.

[0029] As Figure 4As shown in the figure, use an external level 13 to measure the elevation difference between the elevation sample point 10 and the simulated base plate 8, and calculate whether the elevation of the simulated base plate 8 meets the design requirements. EL = H + (H1 - H2), where EL is the designed elevation value of the simulated base plate 8, H is the actual elevation value of the elevation sample point 10, H1 is the actual elevation difference from the level line to the elevation sample point 10, and H2 is the actual elevation difference from the level line to the top of the simulated base plate 8. The required adjustment amount ΔH of the elevation of the simulated base plate 8 = (H1 - H2) - (EL - H).

[0030] On the simulated foundation embedded plate 4, there are permanent X azimuth lines 41 and Y azimuth lines 42 ( Figure 3 The X azimuth line 41 and Y azimuth line 42 marked in the figure are for illustration. The permanent X azimuth line 41 and Y azimuth line 42 are actually located on the simulated foundation embedded plate 4). When in use, hang a piano wire and a plumb bob (i.e., the X azimuth reference line and Y azimuth reference line) on the XY azimuth reference line suspension bracket 2. After aligning with the X azimuth line 41 and Y azimuth line 42, use the X azimuth reference line and Y azimuth reference line as the reference for azimuth adjustment. The specific method of hanging the X azimuth reference line and Y azimuth reference line with plumb bobs on the XY azimuth reference line suspension bracket 2 and aligning them with the X azimuth line 41 and Y azimuth line 42 is to hang the X azimuth reference line and Y azimuth reference line on the XY azimuth reference line suspension bracket 2 with reference to the X azimuth line 41 and Y azimuth line 42. At both ends of the X azimuth reference line and Y azimuth reference line, hang a small plumb bob at a 90° angle and the wire has no kinking points. Take two points on each of the X azimuth line 41 and Y azimuth line 42 of the simulated foundation embedded plate 4. Press the base of the wide-seat angle gauge on the taken points, and the scale head is close to the suspended X azimuth reference line or Y azimuth reference line. Adjust the X azimuth reference line and Y azimuth reference line until they just touch the angle gauge.

[0031] The XY azimuth adjustment line suspension bracket 9 is provided on the simulated foundation mother board 6 for hanging the X azimuth adjustment line and Y azimuth adjustment line. The X azimuth reference line, Y azimuth reference line, X azimuth adjustment line, and Y azimuth adjustment line are made of piano wire or cotton thread, and a plumb bob is connected to the end.

[0032] Specifically, on the simulated foundation mother board 6, there are four XY azimuth adjustment line suspension brackets 9 respectively on the X positive azimuth, X negative azimuth opposite to the X azimuth line 41, and Y positive azimuth, Y negative azimuth opposite to the Y azimuth line 42. The edge of the simulated foundation mother board 6 extends with connecting ears with screw holes relative to the four XY azimuth adjustment line suspension brackets 9, as shown in Figure 3As shown in the figure, any XY azimuth adjustment wire suspension bracket 9 includes a first rotating rod 91 and a second screw rod 92. One end of the first rotating rod 91 is connected to the connecting ear by a bolt, and the other end of the first rotating rod 91 is threadedly connected to the second screw rod 92. The X azimuth adjustment wire and the Y azimuth adjustment wire are suspended on the second screw rod 92. By rotating the first rotating rod 91, the height of the X azimuth adjustment wire and the Y azimuth adjustment wire can be adjusted, and by screwing the second screw rod 92, the distance between the X azimuth adjustment wire and the Y azimuth adjustment wire and the X azimuth reference line and the Y azimuth reference line can be adjusted.

[0033] A permanent Y line is provided on the simulation base plate 8, and the X line on the simulation base plate 8 is drawn by the trainee himself. After the X line and the Y line are determined, the center of the simulation base plate 8 can be further determined. The trainee uses a piano wire (or cotton thread, determined according to the adjustment accuracy requirements) and a plumb bob on the XY azimuth adjustment wire suspension bracket 9, and uses a wide seat angle gauge to align the piano wire with the X line and the Y line of the simulation base plate 8. The alignment of the piano wire can be finely adjusted by screwing the second screw rod 92, and the height adjustment can be adjusted by rotating the first rotating rod 91.

[0034] The X line and the Y line of the simulation base plate 8 and the permanent X azimuth line 41 and Y azimuth line 42 on the simulation base embedded plate 4 are aligned and adjusted through the piano wire and the plumb bob (i.e., the X azimuth adjustment wire and the Y azimuth adjustment wire) suspended on the XY azimuth adjustment wire suspension bracket 9 and the piano wire and the plumb bob (i.e., the X azimuth reference line and the Y azimuth reference line) suspended on the XY azimuth reference line suspension bracket 2. The center of the simulation base plate 8 is adjusted through the adjusted center line and the center plumb bob 11 suspended on the center line. Align the tip of the center plumb bob 11 with the concave pit on the center template 3 and visually inspect from 4 symmetric directions.

[0035] In this embodiment, as Figure 2 shown, the simulation base plate 8 includes two types, namely, a simulation circular base plate and a simulation square base plate, which are used to realize the adjustment skill training of two different-shaped devices. The upper plane and the lower plane of the simulation base plate 8 are parallel to each other, and the upper plane and the lower plane of the simulation base mother plate 6 are parallel to each other. The lower plane of the simulation base plate 8 is subjected to finish machining with a Ra of 1.6, the upper plane is subjected to finish machining with a Ra of 6.3, the upper and lower planes of the simulation base mother plate 6 are both subjected to finish machining with a Ra of 6.3, and the upper plane of the simulation base embedded plate 4 is subjected to finish machining with a Ra of 6.3.

[0047] S23: Slightly loosen the simulated anchor bolts 7, and gently tap the simulated base plate 6 with a copper hammer to make the plumb line of any suspended small plumb bob slightly close to the X-direction reference line or Y-direction reference line suspended on the XY-orientation reference line suspension bracket 2, and ensure that the line on the small plumb bob does not get folded. Conduct inspection work when the small plumb bob does not shake or the shaking is not obvious;

[0048] S24: After the plumb line of any suspended small plumb bob is slightly close to the X-direction reference line or Y-direction reference line suspended on the XY-orientation reference line suspension bracket 2, tighten the simulated anchor bolts 7. Use a ruler to check the deviation between the plumb line of any suspended small plumb bob and the X-direction reference line or Y-direction reference line suspended on the XY-orientation reference line suspension bracket 2.

When the center plumb bob 11 stops shaking significantly, observe the tip of the center plumb bob 11 moving towards the center point on the center template 3 until the tip of the center plumb bob 11 is basically coincident with the center point of the center template 3;

[0053] S34: Tighten the simulated anchor bolts 7.

When the simulated anchor bolt 7 is tightened and causes the level to exceed the tolerance, stop tightening the simulated anchor bolt 7 at the current position, and use a hammer to tighten the elevation adjustment wedge plates 5 on both sides of the current simulated anchor bolt 7 to make the level qualified. When the level still does not change after tightening the elevation adjustment wedge plates 5, first loosen the current simulated anchor bolt 7 and then tighten the elevation adjustment wedge plates 5;
