[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-Figure 11 , which is the first embodiment of the present invention, and this embodiment provides an automatic regulating device for a hydraulic gate. The automatic regulating device for a hydraulic gate includes a main body assembly 100, including a support frame 101, a gate 102 and a gate pier 103. The gate 102 is arranged on the support frame 101, and the gate pier 103 is located on one side of the support frame 101.

[0031] The support frame 101 is used to support and position the gate 102, and the gate pier 103 supports and positions the support frame 101. By adjusting the opening of the gate 102, the water level of the reservoir can be controlled. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0032] The silt removal assembly 200 is arranged on one side of the gate 102, and includes a silt blocking member 201. The silt blocking member 201 includes a filter plate 201a and a first spring 201b. The filter plate 201a is arranged on one side of the gate 102. The gate pier 103 is provided with a sliding groove 103-1. The filter plate 201a slides in the sliding groove 103-1. The two ends of the first spring 201b are fixed to the support frame 101 and the gate 102.

[0033] The silt retaining member 201 is provided to prevent silt from being directly accumulated near the gate 102 under the impact of water flow, thereby affecting the opening and closing of the gate 102. A filter screen is provided in the filter plate 201a, and the silt will be impacted by the water flow onto the filter screen and adhere to it. As the accumulated silt increases, the filter plate 201a will be pushed to move toward the gate 102, thereby compressing the first spring 201b.

[0034] The dredging assembly 200 also includes a dredging member 202, which is located on the filter plate 201a. The dredging member 202 includes a moving plate 202a, a rotating column 202b, a block 202c, a second spring 202d, a gear 202e and a rack 202f. A slide groove 201a-1 is provided in the filter plate 201a. The moving plate 202a slides in the slide groove 201a-1. One end of the rotating column 202b is connected to the inner wall bearing of the slide groove 201a-1. A spiral groove 202b-1 is provided in the rotating column 202b, the block 202c is fixed in the moving plate 202a, the block 202c can slide in the spiral groove 202b-1, the two ends of the second spring 202d are fixed to the moving plate 202a and the inner wall of the sliding groove 201a-1, the gear 202e is fixed to one end of the rotating column 202b, the rack 202f is fixed to the sliding groove 103-1, and the rack 202f is meshed with the gear 202e.

[0035] The silt removal element 202 is provided to scrape off the silt accumulated on the filter plate 201a and transfer it out of the waterway, thereby reducing the silt accumulation near the gate 102 and ensuring the normal and stable operation of the gate 102.

[0036] In the initial state, the movable plate 202a is located away from the screw feeder 202g. Through the cooperation between the block 202c and the spiral groove 202b-1, the rotating column 202b can drive the movable plate 202a to move along the rotating column 202b when rotating, so that the movable plate 202a slides in the slide groove 201a-1, and the second spring 202d applies a pulling force to the movable plate 202a, so that the movable plate 202a can move along the slide groove 201a-1 toward the direction of the screw feeder 202g, thereby scraping off the sludge attached to the filter plate 201a.

[0037] When the filter plate 201a returns to the initial position under the push of the first spring 201b by meshing the rack 202f with the gear 202e, the gear 202e rotates to drive the rotating column 202b to rotate, so that the block 202c slides in the spiral groove 202b-1, and the movable plate 202a moves in the opposite direction to the initial position.

[0038] The pitch of the spiral groove 202b-1 is relatively large, thereby ensuring that when the filter plate 201a is restored and the gear 202e drives the rotating column 202b to rotate, the block 202c can have a relatively long displacement along the spiral groove 202b-1, so that the movable plate 202a can return to its initial position.

[0039] The adjusting assembly 300 is disposed on the gate 102 , and includes a screw rod 301 and a gate hoist 302 . The screw rod 301 is disposed on the upper portion of the gate 102 , and the gate hoist 302 is disposed on the top of the support frame 101 .

[0040] A lifting lug is provided on the gate 102, and the lifting lug is hinged to the screw 301. Through the cooperation between the screw 301 and the gate opening and closing machine 302, the rotational motion of the screw 301 is converted into the linear motion of the nut or the screw 301 itself to drive the gate 102 to rise and fall. This is the prior art, and this scheme will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0041] Example 2

[0042] Reference Figure 1-Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the dredging assembly 200 also includes a locking piece 203, which is arranged on the filter plate 201a, including a first locking block 203a, a third spring 203b and a plug plate 203c. A first moving groove 202a-1 is opened in the movable plate 202a, the first locking block 203a slides in the first locking block 203a, the third spring 203b is fixed to one side of the first locking block 203a, the filter plate 201a is opened with a first locking groove 201a-2, the first locking block 203a is engaged with the first locking groove 201a-2, and the plug plate 203c is fixed on the gate pier 103.

[0044] The locking member 203 is used to lock the relative position of the movable plate 202a to the filter plate 201a, so that the movable plate 202a can be kept on one side of the filter plate 201a. When the sludge on the filter plate 201a accumulates to a certain extent, the movable plate 202a will move to scrape off the sludge.

[0045] The third spring 203b applies continuous thrust to the first locking block 203a to ensure that the first locking block 203a can be engaged with the first locking groove 201a-2. The plug plate 203c is L-shaped, and the shape and size of one side of the plug plate 203c are consistent with the first locking groove 201a-2.

[0046] In the initial state, the first locking block 203a is engaged with the first locking groove 201a-2. As the sludge accumulated on the filter plate 201a increases and under the action of the water flow, the filter plate 201a will move toward the direction of the gate 102. When the plug plate 203c contacts the first locking block 203a, the filter plate 201a continues to move, which will compress the third spring 203b, thereby causing the first locking block 203a to gradually move away from the first locking groove 201a-2. When the two are completely separated, the movable plate 202a is unlocked, and under the pull of the second spring 202d, the movable plate 202a moves along the slide groove 201a-1 toward the direction of the screw feeder 202g, thereby scraping off the sludge attached to the filter plate 201a.

[0047] When the filter plate 201a is reset and drives the movable plate 202a away from the rotary feeder 202g, the first locking block 203a moves to a coaxial position with the first locking groove 201a-2, and the two engage again to limit the movement of the movable plate 202a.

[0048] Specifically, the locking member 203 also includes a second locking block 203d, an extension plate 203e and a fourth spring 203f. The gate pier 103 is provided with a second movable groove 103-2. The second locking block 203d slides in the second movable groove 103-2. The extension plate 203e is fixed to one side of the second locking block 203d. The two ends of the fourth spring 203f are fixed to the extension plate 203e and the inner wall of the second movable groove 103-2.

[0049] The fourth spring 203f applies continuous thrust to the extension plate 203e. A guide column 203l is fixed in the second movable groove 103-2. A guide groove corresponding to the guide column 203l is opened in the extension plate 203e. The two are engaged to ensure that the second locking block 203d and the extension plate 203e move smoothly in the second movable groove 103-2.

[0050] Specifically, one end of the second locking block 203d is inclined, and the filter plate 201a is provided with a second locking groove 201a-3, and the second locking block 203d can be engaged with the second locking groove 201a-3.

[0051] By means of the inclined setting, when the filter plate 201a moves toward the gate 102, the end face of the filter plate 201a will first contact with the second locking block 203d and squeeze the inclined surface of the second locking block 203d to compress the fourth spring 203f, so that the second locking block 203d will not affect the movement of the filter plate 201a. When the filter plate 201a moves to a coaxial position with the second locking groove 201a-3, the second locking block 203d engages with the second locking groove 201a-3, and the position of the filter plate 201a is fixed.

[0052] Specifically, the filter plate 201a is provided with a through groove 201a-4, an extrusion plate 203g is arranged in the through groove 201a-4, an extension block 203h is fixed to one side of the extrusion plate 203g, and the filter plate 201a is provided with a third movable groove 201a-5, and the extension block 203h slides in the third movable groove 201a-5.

[0053] The squeezing plate 203g is used to unlock the engagement state between the second locking block 203d and the second locking groove 201a-3. When the movable plate 202a moves toward the direction of the screw feeder 202g, the movable plate 202a will first contact the squeezing plate 203g and squeeze it, thereby causing the squeezing plate 203g to move toward the direction of the screw feeder 202g. One side of the squeezing plate 203g moves into the second moving groove 103-2 through the through groove 201a-4, and squeezes the extension plate 203e, thereby causing the extension plate 203e to move with the second locking block 203d, thereby unlocking the engagement between the second locking block 203d and the second locking groove 201a-3, thereby unlocking the lock of the filter plate 201a, so that the filter plate 201a can return to its initial state under the push of the first spring 201b.

[0054] The extension block 203h is used to support and position the extrusion plate 203g.

[0055] Specifically, a fifth spring 203i is fixed to one side of the extension block 203h, and the other end of the fifth spring 203i is fixed to the inner wall of the third moving groove 201a-5.

[0056] The fifth spring 203i applies a thrust to the extension block 203h. When the extrusion plate 203g squeezes the extension plate 203e, the fifth spring 203i is in a compressed state. When the movable plate 202a moves away from the extrusion plate 203g, the fifth spring 203i will push the extension block 203h to reset, thereby returning the extrusion plate 203g to its initial position.

[0057] Example 3

[0058] Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0059] Specifically, an annular groove 202b-2 is formed on the rotating column 202b, and the clamping block 202c slides on the annular groove 202b-2.

[0060] The annular groove 202b-2 is provided to ensure that when the movable plate 202a is in the initial position, as the sludge attached to the filter plate 201a increases, the filter plate 201a moves toward the gate 102. At this time, since the gear 202e is engaged with the rack 202f, when the filter plate 201a moves, the gear 202e will rotate, thereby driving the rotating column 202b to rotate. Since the first locking block 203a is engaged with the first locking groove 201a-2, the movable plate 202a is in a locked state at this time. When the gear 202e rotates, the block 202c will slide in the annular groove 202b-2, and will not affect the rotation of the rotating column 202b, thereby ensuring that the gear 202e can rotate normally.

[0061] There is no tooth block at one end of the rack 202f. When the filter plate 201a moves toward the gate 102, when the filter plate 201a is about to move to the end face of the sliding groove 103-1, the gear 202e moves to the rack 202f without a tooth block, so as to ensure that when the moving plate 202a is unlocked and moves in the direction of the screw feeder 202g, the rotating column 202b drives the gear 202e to rotate. At this time, the gear 202e is not engaged with the rack 202f, and thus will not affect the movement of the moving plate 202a.

[0062] Specifically, a screw feeder 202g is provided on one side of the filter plate 201a, and a motor 202h is fixed on the top of the screw feeder 202g.

[0063] The screw feeder 202g is used to transfer the sludge scraped from the filter plate 201a out of the waterway, thereby ensuring the dredging effect and reducing the resistance of driving the gate 102.

[0064] Specifically, a fixing column 201i is fixed on the filter plate 201a, a fixing block 201j is fixed on one side of the support frame 101, and an electrode sheet 201k is provided on both the fixing column 201i and the fixing block 201j.

[0065] The movement of the filter plate 201a will drive the fixed column 201i to move synchronously. When the filter plate 201a moves to the end face of the sliding groove 103-1 close to the gate 102, the electrode sheet 201k on the fixed column 201i will fit with the electrode sheet 201k on the fixed block 201j. After the two fit together, the motor 202h is started to make the screw feeder 202g start to transport the sludge. When the filter plate 201a moves in the opposite direction under the action of the first spring 201b, the electrode sheet 201k on the fixed column 201i will separate from the electrode sheet 201k on the fixed block 201j, and the motor 202h will automatically turn off. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0066] Specifically, the main body component 100 further includes a water channel bottom wall 104 , and the water channel bottom wall 104 is disposed at the bottom of the support frame 101 .

[0067] The screw feeder 202g is fixed to the bottom wall 104 of the waterway by bolts.

[0068] When in use, in the initial state, the first spring 201b is in a relaxed state, the distance between the filter plate 201a and the gate 102 is the largest, the moving plate 202a is located away from the screw feeder 202g, and the position is locked.

[0069] Under the action of water flow, silt will accumulate on the filter plate 201a and squeeze the filter plate 201a, compressing the first spring 201b, and the filter plate 201a will move along the sliding groove 103-1 toward the gate 102, and the block 202c slides in the annular groove 202b-2, and the relative position of the movable plate 202a and the filter plate 201a will not change. As the filter plate 201a moves, when the plug plate 203c contacts the first locking block 203a, the filter plate 201a continues to move, which will compress the third spring 203b, so that the first locking block 203a gradually moves away from the first locking groove 201a-2. When the two are completely separated, the movable plate 202a is unlocked, and under the pull of the second spring 202d, the movable plate 202a moves along the sliding groove 201a-1 toward the direction of the screw feeder 202g, thereby scraping off the silt attached to the filter plate 201a.

[0070] At the same time, when the filter plate 201a moves toward the gate 102, the end face of the filter plate 201a will first contact the second locking block 203d and squeeze the inclined surface of the second locking block 203d to compress the fourth spring 203f, so that the second locking block 203d will not affect the movement of the filter plate 201a. When the filter plate 201a moves to a coaxial position with the second locking groove 201a-3 with the second locking groove 201a-3, the second locking block 203d engages with the second locking groove 201a-3. At this time, the position of the filter plate 201a is fixed, and the movement of the filter plate 201a will drive the fixed column 201i to move synchronously. When the filter plate 201a moves to the end face of the sliding groove 103-1 close to the side of the gate 102, the electrode sheet 201k on the fixed column 201i will fit with the electrode sheet 201k on the fixed block 201j. After the two fit together, the motor 202h is started to make the screw feeder 202g start to transport sludge.

[0071] After the filter plate 201a is locked, the gear 202e follows the filter plate 201a to move to the side of the rack 202f without a tooth block. When the moving plate 202a moves toward the screw feeder 202g, the moving plate 202a will first contact the extrusion plate 203g and squeeze it, so that the extrusion plate 203g moves toward the screw feeder 202g. One side of the extrusion plate 203g moves into the second moving groove 103-2 through the through groove 201a-4 and extends the extension plate 202g. 03e is squeezed, thereby moving the extension plate 203e and the second locking block 203d, thereby unlocking the engagement between the second locking block 203d and the second locking groove 201a-3, thereby unlocking the filter plate 201a, and under the push of the first spring 201b, the filter plate 201a moves along the sliding groove 103-1 away from the gate 102, the electrode sheet 201k on the fixing column 201i will be separated from the electrode sheet 201k on the fixing block 201j, and the motor 202h will be automatically turned off.

[0072] The filter plate 201a moves, the rack 202f engages with the gear 202e, causing the gear 202e to rotate, and the block 202c slides in the spiral groove 202b-1, thereby driving the rotating column 202b to rotate, and then the movable plate 202a moves along the rotating column 202b to the initial position. When the first locking block 203a moves to a coaxial position with the first locking groove 201a-2, the two engage again to limit the movement of the movable plate 202a.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
