[0036] Reference for installation method of silt cleaning device at bottom channel of hydropower station gate Figure 1 The guide rail 1 is installed above the gate body 21, the three-dimensional frame 3 is located behind the gate 22, the three-dimensional frames 3 are respectively called the first three-dimensional frame 3, the second three-dimensional frame 3 and the third three-dimensional frame 3 from right to left, and the bottom frames 4 are respectively called the first bottom frame 4, the second bottom frame 4 and the third bottom frame 4 from right to left; the water flow direction is from front to back, and the impurities in the water are intercepted in the three-dimensional frame 3 through the filtering effect of the filter 5; initially, the hook 10 hooks the cross bar 6 on the first three-dimensional frame 3, and the first bottom frame 4 is flush with the protrusion 111 at the Z-axis position.

[0037] The lifting method of the lifting frame 8 and the hook 10 is as follows: under the transmission action of the gear box 84, the servo motor 83 is controlled to make the two winding drums 81 rotate synchronously, the winding drum 81 loosens the steel rope 82, and the lifting frame 8, the rotating rod 9 and the hook 10 descend by gravity; the servo motor 83 is controlled to make the two winding drums 81 reverse synchronously, the winding drum 81 winds up the steel rope 82, the steel rope 82 pulls the lifting frame 8 to rise, and the lifting frame 8 drives the rotating rod 9 and the hook 10 to rise.

[0038] In the first step, the electric roller 72 is controlled to rotate clockwise. Under the action of friction, the electric roller 72 rolls to the right in the guide groove 73, driving the translation frame 7, the lifting frame 8, the winding disk 81, the steel rope 82, the rotating rod 9, the hook 10, the first three-dimensional frame 3, the cross bar 6 and the first bottom frame 4 to translate to the right as a whole on the X axis. When the right side of the first bottom frame 4 contacts the left side of the protrusion 111, the first bottom frame 4 is blocked by the protrusion 111, and the first bottom frame 4 stops moving to the right, while the translation frame 7, the lifting frame 8, the winding disk 81, the steel rope 82, the rotating rod 9, the hook 10, the first three-dimensional frame 3 and the cross bar 6 continue to move to the right, and the first bottom frame 4 becomes Figure 5 In the open state shown, most of the sediment in the first three-dimensional frame 3 falls to the bank on the right side of the connecting strip 11 by gravity, and the filter screen 5 is manually cleaned to clean the sediment in the three-dimensional frame 3.

[0039] The second step is to control the electric roller 72 to rotate counterclockwise, and the electric roller 72 rolls to the left in the guide groove 73, driving the translation frame 7, the lifting frame 8, the winding disk 81, the steel rope 82, the rotating rod 9, the hook 10, the first three-dimensional frame 3, the cross bar 6 and the first bottom frame 4 to translate to the left on the X axis as a whole. When the left side of the first bottom frame 4 contacts the right side of the blocking bar 112, the first bottom frame 4 is blocked by the blocking bar 112, and the first bottom frame 4 stops moving to the left, while the translation frame 7, the lifting frame 8, the winding disk 81, the steel rope 82, the rotating rod 9, the hook 10, the first three-dimensional frame 3 and the cross bar 6 continue to move to the left, and the first bottom frame 4 becomes Figure 2 Shown in closed state.

[0040] In the third step, the lifting frame 8 and the hook 10 are lowered, driving the cross bar 6, the first three-dimensional frame 3 and the first bottom frame 4 to descend as a whole, so that the first three-dimensional frame 3 and the first bottom frame 4 are lowered to the rear of the right gate 22, and the limit rod 2 limits the three-dimensional frame 3 to prevent the three-dimensional frame 3 from moving in the Y-axis direction; Figure 8 Under the transmission action of the gear set 92, the reduction motor 91 is controlled to rotate the two rotating rods 9 by 45 degrees. The front rotating rod 9 rotates counterclockwise, and the rear rotating rod 9 rotates clockwise. The hook 10 rotates with the rotating rod 9. The hook 10 no longer hooks the cross bar 6. The lifting frame 8 and the hook 10 rise to Figure 3 The initial height of .

[0041] In the fourth step, the electric roller 72 rotates counterclockwise, the translation frame 7, the lifting frame 8, the winding drum 81, the steel rope 82, the rotating rod 9 and the hook 10 move to the left to the top of the second three-dimensional frame 3, the lifting frame 8 and the hook 10 descend to the height where the hook 10 is close to the cross bar 6 on the second three-dimensional frame 3, the reduction motor 91 is controlled to make the rotating rod 9 and the hook 10 reverse 45 degrees together, the hook 10 hooks the cross bar 6 on the second three-dimensional frame 3, the lifting frame 8 and the hook 10 rise, the hook 10 pulls the cross bar 6, so that the second three-dimensional frame 3 and the second bottom frame 4 move up, and the second bottom frame 4 rises to a height higher than the baffle 112.

[0042] In the fifth step, the electric roller 72 rotates clockwise, and the translation frame 7, the lifting frame 8, the steel rope 82, the rotating rod 9, the hook 10, the second three-dimensional frame 3, the cross bar 6 and the second bottom frame 4 move right as a whole. Since the second bottom frame 4 is higher than the baffle bar 112, the second bottom frame 4 will pass over the baffle bar 112, and the second three-dimensional frame 3 moves right to just above the first three-dimensional frame 3.

[0043] In the sixth step, the lifting frame 8 and the hook 10 are lowered, and the second three-dimensional frame 3 is lowered, so that the second bottom frame 4 is lowered to a position flush with the protrusion 111 on the Z axis. At this time, the movement principle is the same as that of the first three-dimensional frame 3. The first step is repeated to open the second bottom frame 4, and the silt in the second three-dimensional frame 3 falls down. Then the second step is repeated to close the second bottom frame 4; then the lifting frame 8 and the hook 10 are raised, and the second three-dimensional frame 3 and the second bottom frame 4 are raised to make the second bottom frame 4 higher than the baffle 112. The second three-dimensional frame 3 and the second bottom frame 4 can move to the left and cross the baffle 112. Similarly, the second three-dimensional frame 3 is reset to the initial position. Finally, the silt in the third three-dimensional frame 3 is cleaned.

[0044] In this way, through the cooperation of the lifting mechanism and the translation mechanism, the three-dimensional frame 3 can be automatically moved to the bank of the hydropower station to clear the silt. The moving process of the three-dimensional frame 3 is automated, and the silt clearing efficiency is high.

[0045] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 , Figure 3 and Fig. 9 The hydropower station gate bottom trough silt cleaning device also includes a connecting frame 121, an inclined plate 122 and a roller 123. The connecting frame 121 is fixedly connected to the right side of the connecting bar 11, an inclined plate 122 is provided in the middle of the connecting frame 121, and two symmetrical rollers 123 are rotatably connected to the bottom of the connecting frame 121.

[0046] When the bottom frame 4 is opened, the silt in the three-dimensional frame 3 falls onto the inclined plate 122, and the inclined plate 122 plays a guiding role, which facilitates the centralized treatment of the silt. When the installation position of the connecting strip 11 is adjusted, the connecting frame 121, the inclined plate 122 and the roller 123 will move synchronously with the connecting strip 11, and the roller 123 plays a role in reducing friction.

[0047] Embodiment 3: Based on Embodiment 2, refer to Figure 1 , Figure 2 and Fig.11 The hydropower station gate bottom trough silt cleaning device also includes a blocking mechanism, which includes a connecting plate 131, an electric push rod 132 and a filter frame 133.

The telescopic rods of the electric push rods 132 are fixedly connected with filter frames 133.

[0048] The method for opening and closing the filter frame 133 is as follows: when the filter frame 133 is in the open state, the telescopic rod of the electric push rod 132 is controlled to extend, driving the filter frame 133 to descend, and the filter frame 133 becomes the closed state, and then the telescopic rod of the electric push rod 132 is controlled to shorten, the filter frame 133 rises, and the filter frame 133 is opened again.

[0049] like Figure 2 As shown, when the three-dimensional frame 3 is in an ascending state, the filter frame 133 directly below it is closed, and the filter frame 133 continues to block impurities in the water to prevent impurities in the water from passing through the gate 22. When the three-dimensional frame 3 is in a descending state, the filter frame 133 directly below it is opened, and the impurities are blocked by the three-dimensional frame 3.

[0050] refer to Figure 1 , Figure 2 , Fig.11 and Fig.12 The hydropower station gate bottom trough silt cleaning device also includes a cutting mechanism, which includes a fixed frame 141 and a saw chain 142. The lower front part of the filter frame 133 is fixedly connected to the fixed frame 141, and the saw chain 142 is installed on the fixed frame 141. The structure and principle of the saw chain 142 are prior art.

[0051] When the filter frame 133 descends and closes, the fixed frame 141 descends together with the filter frame 133 to control the saw chain 142 to rotate. The saw chain 142 can cut off a small amount of long impurities in the three-dimensional frame 3, such as weeds and slender branches, to avoid affecting the ascent of the three-dimensional frame 3.
