Abstract

This application relates to a reservoir sediment discharge device, which includes a sediment discharge plate located within the reservoir and a drive device. The drive device includes a drive plate inserted into the sediment discharge plate and a motor. The drive plate is bent to form an extension rod extending to the bank of the reservoir. A support seat for supporting the motor is installed on the extension rod, and a roller driven by the motor is installed at the bottom of the support seat. The motor drives the sediment discharge plate to move and concentrate sediment, which is then pumped out by a sediment pump. This application uses a motor to drive the extension rod and drive plate, with the drive plate inserted into the sediment discharge plate. This movement of the sediment discharge plate pushes the sediment and silt to concentrate in one place, which is then pumped out by a sediment pump.

Compared to conventional methods of directly pumping sediment, the efficiency of sediment discharge and silt removal is also improved.

Description

Technical Field

[0001] This application relates to the technical field of water conservancy engineering equipment, and in particular to a reservoir sediment discharge device. Background Technology

[0002] In reservoirs of rivers with high sediment content, sediment is deposited due to factors such as increased water surface area and reduced water flow velocity, which can easily lead to siltation and loss of reservoir capacity.

[0003] Current reservoir sediment flushing methods typically achieve their effect by increasing discharge volume and water flow velocity. However, this method involves high water consumption, so the applicant believes that current reservoir sediment flushing technology still needs improvement. Summary of the Invention

[0004] To reduce the large amount of water used for sand removal, this application provides a reservoir sand removal device.

[0005] The reservoir sediment removal equipment provided in this application adopts the following technical solution:

[0006] A reservoir sediment discharge device includes a sediment discharge plate located in the reservoir and a drive device. The drive device includes a drive plate inserted into the sediment discharge plate and a motor. The drive plate is bent to form an extension rod extending to the bank of the reservoir. A load-bearing seat supporting the motor is installed on the extension rod. A roller driven by the motor is installed at the bottom of the load-bearing seat. The motor drives the sediment discharge plate to move and concentrate the sediment, which is then pumped out by a sediment pump.

[0007] By adopting the above technical solution, the extension rod and drive plate are driven by the motor. The drive plate is inserted into the sand discharge plate, so that the movement of the sand discharge plate pushes the mud and silt to concentrate in one place. Then, the mud and sand are pumped out, thus eliminating the need to increase the discharge flow rate and the water flow velocity, reducing the amount of water required for sand discharge. Moreover, compared with the conventional method of directly pumping mud and sand, the efficiency of sand discharge and silt removal is also improved.

[0008] Preferably, the driving device further includes a mating plate, which is inserted into the sand discharge plate on the side opposite to the driving plate. The mating plate is bent to form a support rod extending toward the extension rod. A telescopic rod is movably connected to the support rod, and the extension rod has an insertion slot for the telescopic rod to be inserted.

[0009] By adopting the above technical solution, the support rod on the mating rod supports the telescopic rod, and the telescopic rod is inserted into the insertion slot to realize the linkage between the mating plate and the drive plate, thereby achieving the process of stably driving the sand discharge plate to move.

[0010] Preferably, inclined reinforcing plates are fixed between the corresponding extension rod and drive plate, as well as between the corresponding mating plate and support rod; positioning sleeves that abut against the sand discharge plate are sleeved and fixed at the ends of the drive plate and mating plate.

[0011] By adopting the above technical solution, the structural strength is improved by fixing reinforcing plates between the extension rod and the drive plate, and between the mating plate and the support rod, making the movement of the sand discharge plate more stable. The positioning sleeve plays a positioning role for the sand discharge plate, which can prevent the sand discharge plate from coming off from the ends of the drive plate and the mating plate.

[0012] Preferably, at least one spare plate can be stacked at the sand discharge plate, and the spare plate is connected to the sand discharge plate through a connecting structure.

[0013] By adopting the above technical solution, the usage requirements can be met when the height of sediment accumulation increases during the sediment concentration process. At the same time, when the height of sediment accumulation is high, additional spare plates can be added to increase the sediment discharge height of the discharge plate, thereby expanding the applicability of the sediment discharge equipment and improving its practicality.

[0014] Preferably, the spare plate is provided with mating holes for the drive plate and the mating plate to be inserted; the sand discharge plate is provided with a positioning groove for the spare plate to be inserted; the connecting structure includes a rotating plate rotatably connected to the side wall of the sand discharge plate and a connecting column movably connected to the movable end of the rotating plate, and the connecting column is inserted and positioned on the sand discharge plate; the rotating end of the rotating plate is located on the side close to the spare plate, and the side wall of the spare plate is provided with a connecting groove for the connecting column to be inserted and positioned.

[0015] By adopting the above technical solution, the positioning groove is set for the initial connection of the spare plate and the sand discharge plate, and the mating hole is opened so that the spare plate can be connected with the drive plate and the mating plate, thereby moving synchronously with the sand discharge plate; after the rotating plate on the sand discharge plate rotates, the connecting column is inserted into the connecting groove on the spare plate. No additional parts are needed, and the operation is convenient while achieving a stable connection.

[0016] Preferably, the end of the connecting post is formed with a connecting thread, and the side wall of the connecting groove near the bottom of the groove is formed with a mating thread that mates with the connecting thread on the connecting post.

[0017] By adopting the above technical solution, the connecting thread and mating thread are set at the end, which helps to shorten the rotation and fixing time of the connecting column, makes the fixing operation more convenient, and can further improve the connection stability of the sand discharge plate and the spare plate.

[0018] Preferably, when multiple spare plates are stacked, the rotating plates on the spare plates adjacent to the sand discharge plate are staggered left and right; and the rotating plates on two adjacent spare plates are staggered, that is, the rotating plates and connecting grooves on the same spare plate are adjacent to each other; and an installation groove for inserting the next spare plate is opened at the bottom of the previous spare plate.

[0019] By adopting the above technical solution, the rotating plate is set in a staggered structure, thereby avoiding the problem of mutual obstruction between the connecting groove used to fix the connecting column on the same spare plate and the rotating plate structure when multiple spare plates are stacked, and the overall structure is more reasonable; the spare plates are stacked from below, making installation more convenient.

[0020] Preferably, a load-bearing block is placed inside the load-bearing seat; the extension rod is inserted and positioned inside the side wall of the load-bearing seat.

[0021] By adopting the above technical solution, the load-bearing block increases the weight of the load-bearing seat, making it easier for the load-bearing seat to overcome the resistance of the mud and sand and drive the sand discharge plate to move, so that the sand discharge plate can push the mud and sand to achieve the purpose of concentration; the extension rod is inserted and positioned on the side wall of the load-bearing seat, making installation convenient.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The rollers on the load-bearing base are moved by the motor, and the load-bearing base drives the drive plate and the mating plate to move, thereby indirectly achieving the purpose of moving the sand discharge plate. In this way, the sand discharge plate can be used to collect the mud and sand in one place, without the need to increase the amount of water to carry out the sand discharge process, which makes the operation of pumping mud and sand more convenient and helps to improve the sand discharge efficiency.

[0024] 2. The stacking of spare plates on the sand discharge plate can increase the sand discharge height of the sand discharge plate. On the one hand, it can be used for sand discharge work with different mud and sand heights, and can also meet the needs when the height increases during the mud and sand concentration process. On the other hand, by using multiple spare plates to stack, the problem of the sand discharge plate being too tall and inconvenient to disassemble and assemble is avoided.

[0025] 3. When stacking spare plates, the rotation of the rotating plate on the sand discharge plate makes the connecting column correspond to the connecting groove on the corresponding spare plate and insert it for fixation, thus connecting the two; and the rotating plates on the spare plates adjacent to the sand discharge plate are staggered left and right, and the rotating plates on two adjacent spare plates are staggered, so that the positioning structures on the sand discharge plate and the spare plates do not interfere with each other, making the setting more reasonable.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Embodiment 1 of this application discloses a reservoir sediment removal device, referring to... Figure 1 The system includes a sand-discharging plate 1 and a driving device 2 located inside the reservoir. Driven by the driving device 2, the sand-discharging plate 1 pushes the sediment deposited at the bottom of the reservoir, thereby concentrating the sediment in one place. After the sediment is concentrated, it is pumped out by a sediment pump, which can reduce the amount of water required for sand discharge and is more efficient than the conventional method of directly pumping sediment.

[0034] Reference Figure 1 The driving device 2 includes a driving plate 21 and a mating plate 22 inserted into the sand discharge plate 1. The upper part of the driving plate 21 is bent to form an extension rod 211 extending to the bank of the reservoir. The mating plate 22 is square and is inserted into the sand discharge plate 1 on the opposite side of the driving plate 21. The mating plate 22 is bent to form a support rod 221 extending toward the extension rod 211. A telescopic rod 222 is movably connected to the support rod 221. The extension rod 211 has an insertion slot 2111 for the telescopic rod 222 to be inserted into, thereby realizing the connection between the support rod 221 and the extension rod 211.

[0035] Reference Figure 1 Positioning sleeves 6 are fixedly fitted at the ends of the drive plate 21 and the mating plate 22. The positioning sleeves 6 can be fixed with bolts. The bottom of the sand discharge plate 1 can abut against the positioning sleeves 6. The positioning sleeves 6 play a positioning role for the sand discharge plate 1, thereby avoiding the problem of the sand discharge plate 1 sliding out from the drive plate 21 and the mating plate 22 after installation. It should be noted that the height of the positioning sleeves 6 has little effect on the sand discharge effect and can be ignored.

[0036] Reference Figure 1 An inclined reinforcing plate 3 is fixedly connected between the extension rod 211 and the drive plate 21, and an inclined reinforcing plate 3 is also fixed between the mating plate 22 and the support rod 221 to improve the structural strength.

[0037] Reference Figure 1 The drive device 2 also includes a motor 23; a load-bearing seat 7 is installed on the extension rod 211, and a load-bearing block 71 is placed inside the load-bearing seat 7. The motor 23 is installed inside the load-bearing seat 7, and a roller 8 driven by the motor 23 is installed at the bottom of the load-bearing seat 7. Thus, the motor 23 drives the roller 8 to roll, driving the extension rod 211 and the support rod 221 to move synchronously, thereby driving the sand discharge plate 1 to move, and more conveniently pushing the sediment at the bottom of the reservoir to concentrate in one place. It should be noted that the roller 8 is located on the side of the extension rod 211 away from the reservoir, and the load-bearing block 71 is located inside the load-bearing seat 7 on the side that is offset from the roller 8 and the extension rod 211, so as to avoid structural conflicts.

[0038] Reference Figure 1 At least one spare plate 4 can be stacked below the sand discharge plate 1. The spare plate 4 is provided with mating holes 41 for the drive plate 21 and the mating plate 22 to be inserted, making the structure more reasonable. When the height of the silt accumulation is high, the spare plate 4 can be stacked to increase the sand discharge height of the sand discharge plate 1, thereby expanding the applicability of the sand discharge equipment and improving its practicality.

[0039] Reference Figure 1 , 2 The bottom of the sand discharge plate 1 is provided with a positioning groove 11 for the insertion of the spare plate 4 to achieve initial connection; the spare plate 4 is further connected and positioned with the sand discharge plate 1 through the connecting structure 5.

[0040] Reference Figure 1 , 3 The connecting structure 5 includes a rotating plate 51 rotatably connected to the opposite side walls of the sand discharge plate 1 and a connecting column 52 movably connected to the movable end of the rotating plate 51. The connecting column 52 is inserted and positioned on the side wall of the sand discharge plate 1. The rotating end of the rotating plate 51 is located near the spare plate 4. The side wall of the spare plate 4 is provided with a connecting groove 42 for the connecting column 52 to be inserted and positioned. When the rotating plate 51 rotates downward, the connecting column 52 can be inserted into the connecting groove 42 on the spare plate 4 to achieve relative positioning of the spare plate 4 and the sand discharge plate 1.

[0041] Reference Figure 1 , 3 The end of the connecting column 52 is formed with a connecting thread 521, and the side wall of the connecting groove 42 near the bottom of the groove is formed with a mating thread 421 that mates with the connecting thread 521 on the connecting column 52, which helps to further improve the connection stability of the sand discharge plate 1 and the spare plate 4.

[0042] Reference Figure 1 , 4When the spare plates 4 are stacked, the rotating plate 51 on the side wall of the spare plate 4 adjacent to the sand discharge plate 1 is staggered left and right; the rotating plates 51 on the upper and lower adjacent spare plates 4 are staggered left and right, that is, the rotating plate 51 and the connecting groove 42 on the same spare plate 4 are arranged adjacent left and right; and the bottom of the upper spare plate 4 is provided with an installation groove 43 for the lower spare plate 4 to be inserted, thereby avoiding the problem of mutual obstruction between the connecting groove 42 and the rotating plate 51 on the same spare plate 4 used to fix the connecting column 52, and the overall structure is more reasonable; the spare plates 4 are stacked from the bottom, which makes installation more convenient; this application only shows the stacking of one spare plate 4 as an example.

[0043] The implementation process of this embodiment is as follows:

[0044] Before placing the sand removal equipment, insert the drive plate 21 and the mating plate 22 into the sand removal plate 1, and insert the telescopic rod 222 into the extension rod 211; then fix the positioning sleeve 6 at the bottom of the drive plate 21 and the mating plate 22 to position the sand removal plate 1.

[0045] When the sediment accumulation at the bottom of the reservoir is high, a spare plate 4 can be installed below the sand discharge plate 1. The mating holes 41 on the spare plate 4 are aligned with the drive plate 21 and the mating plate 22 respectively, so that the drive plate 21 and the mating plate 22 are inserted into the spare plate 4. Then, the spare plate 4 is moved and the upper part is inserted into the positioning groove 11 at the bottom of the sand discharge plate 1. Then, the rotating plate 51 on the sand discharge plate 1 is rotated and the movable end of the rotating plate 51 is aligned with the side wall of the spare plate 4. At this time, the connecting column 52 can be inserted into the connecting groove 42 and fixed to the connecting groove 42 by rotation and threaded connection, thereby realizing a stable connection between the spare plate 4 and the sand discharge plate 1.

[0046] After the sand-discharging plate 1 and the spare plate 4 are placed in the reservoir, the extension rod 211 extends to the bank of the reservoir and is inserted into the load-bearing seat 7. The roller 8 is positioned on the ground of the bank. When the motor 23 is working, it can drive the roller 8 to roll, thereby moving the sand-discharging plate 1 and the spare plate 4.

[0047] When removing the sand discharge plate 1 and the spare plate 4, remove the load-bearing base 7, then rotate the extension rod 211 to rotate the sand discharge plate 1 and the spare plate 4 to a horizontal position and above the water surface of the reservoir, and then move them to the shore.

[0048] Example 2

[0049] The difference from Embodiment 1 is that the mating plate 22 can be set as a cylindrical rotatable shape. When the reservoir volume is large, the length of the sand discharge plate 1 and the spare plate 4 can be extended. Then the support rod 221 can be rotated to the opposite direction of the extension rod 211, and the support rod 221 is located on the reservoir bank opposite to the extension rod 211. Then, a load-bearing seat 7 with rollers 8 is installed on the support rod 221, so that the movement of the sand discharge plate 1 can be driven synchronously from both sides, and the sand discharge effect is better.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
