Technical Field
[0001] This invention belongs to the field of silt removal technology, specifically relating to a sluice gate silt removal device. Background Technology
[0002] A river gate is a type of water conservancy facility used to control parameters such as river water level, flow rate, and velocity for water conservancy activities such as irrigation, flood control, and power generation.
[0003] The accumulation of silt at river sluice gates is a common problem. The accumulation of silt not only narrows the sluice gate, obstructs the water flow, and slows down the flow rate, affecting the water flow at the sluice gate, but also reduces the clarity of the water at the sluice gate and increases the turbidity, affecting the water quality and consequently the ecological environment of the sluice gate, which is detrimental to the survival of aquatic plants and animals.
[0004] Currently, in order to improve the efficiency of silt removal, people set up an appropriate number of silt sedimentation tanks before and after the sluice gate, so that the silt falls and accumulates in the sedimentation tanks due to its own gravity. Then, sand cleaning equipment is used to remove the silt from the sedimentation tanks. Common silt removal devices include dredgers, sand pumping vessels, and silt removal vessels. They all have the same problems: they consume a lot of energy, the cost of sand removal is high, and they have many mechanical components, making them bulky, inflexible, and ineffective.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.
[0045] In the description of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "connected" and "linked" used in this invention should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0047] Example 1: This example aims to provide a gate silt cleaning device, which is mainly used to effectively clean the silt remaining in the sedimentation tank at the gate with low cost and low energy consumption, thereby improving work quality and usage effect.
[0048] Reference Figure 1 and Figure 2The system includes a work platform 1, a sand-cleaning pipe 3, a sand-collecting bucket 5, and an adjustment mechanism. The work platform 1 includes a high platform section 101, a low platform section 102, and a stepped section 103. Both ends of the high platform section 101 extend downwards with stepped sections 103. The low platform section 102 is located at the lower end of the stepped section 103. The high platform section 101 and the low platform section 102 are connected vertically by the stepped section 103. The low platform section 102 and the stepped section 103 are set below the high platform section 101 to facilitate workers to climb from the lower part of the work platform 1 to the higher part. A guardrail 6 is also provided on the side of the work platform 1 to ensure the safety of workers. The stepped section 103 includes an upwardly sloping step surface and a downwardly sloping support surface. The support surface has legs 7 protruding downwards from the embankment on both sides of the gate. The legs 7 are used to support the entire work platform 1.
[0049] Reference Figure 2 and Figure 3 The adjusting mechanism allows the leg column 7 to be moved along the length of the embankment on the side of the gate. The adjusting mechanism includes: an adjusting base 8, an adjusting motor 9, a lead screw 10, and a guide column 11. The adjusting base 8 includes a grab plate 801 and a trough plate 802. The grab plate 801 is U-shaped, and the U-shaped opening of the grab plate 801 is adapted to the embankment on the side of the gate. The grab plate 801 is placed on the embankment on the side of the gate with the U-shaped opening facing down. If necessary, bolts or other fasteners can also be used to secure the grab plate 801. 01. Further fixation with the embankment: The feed trough plate 802 is fixed to the middle of the upper plate surface of the grab plate 801 and integrated with it. The lower end of the leg column 7 extends into the corresponding groove of the feed trough plate 802, ensuring that the lower end of the leg column 7 contacts the bottom surface of the groove of the feed trough plate 802, so that the load of the leg column 7 is transferred to the adjusting base 8. The bottom surface of the groove of the feed trough plate 802 is a rolling surface, which is formed by multiple rotatable rollers 12 laid on the bottom surface of the groove. The rotatable direction of the rollers 12 is the same as the length direction of the groove. The system utilizes a rolling surface to change the sliding friction between the leg column 7 and the bottom surface of the channel of the supply plate 802 into rolling friction, effectively reducing the moving resistance of the leg column 7 in the channel of the supply plate 802, reducing the energy consumed in moving the leg column 7, and saving operating costs. The lead screw 10 is located inside the supply plate 802 below the right leg column 7 and is threadedly fitted with the right leg column 7. A position adjustment motor 9 is externally connected to the lead screw 10 on the right supply plate 802, allowing the lead screw 10 to rotate within the channel of the supply plate 802. The guide column 11 is fixed inside the supply plate 802 below the left leg column 7 and is slidably fitted with the right leg column 7. Through the cooperation of the guide column 11 and the dynamic lower lead screw 10, the leg column 7 moves along the length of the supply plate 802, thereby moving the worktable 1 along the side embankment of the gate. This allows for flexible adjustment of the working position of the worktable 1 to correspond to the sedimentation tank, ensuring smooth operation and work quality.
[0050] Reference Figure 1 , Figure 2 and Figure 4 The sand-cleaning pipe 3 adopts a spiral extraction internal structure. It is vertically mounted in the middle of the elevated section 101 via a drop arm 13. The upper and lower ends of the sand-cleaning pipe 3 are the power unit and the sand-extraction unit, respectively. The power unit is a drive motor, and the sand-extraction unit consists of exposed spiral blades. The upper end of the sand-cleaning pipe 3 passes through the middle of the elevated section 101 and extends upwards for a certain distance to accommodate the drop arm 13. The drop arm 13 includes inclined ribs and vertical ribs. The upper end of the inclined rib is fixed to the pipe wall of the sand-cleaning pipe 3, and the lower end of the inclined rib slopes away from the sand-cleaning pipe 3, connecting with the upper end of the vertical rib. The lower end of the vertical rib penetrates the elevated section 101 and extends downwards for a certain distance. The corner where the inclined rib and the vertical rib meet forms a drop point. When the sand-extraction unit completely detaches from the sediment... Before setting the sedimentation tank, ensure that the vertical ribs do not detach from the elevated section 101. By setting the vertical ribs, the sand-cleaning pipe 3 can be prevented from rotating during the vertical displacement. The lower end of the sand-cleaning pipe 3 is tapered. The sand-cleaning pipe 3 is made of metal and is relatively heavy. The sand-cleaning pipe 3 can extend its lower end into the corresponding sedimentation tank by its own weight, so as to bury the sand pumping part deep in the sedimentation tank. The part of the sand-cleaning pipe 3 that protrudes from the elevated section 101 has a pair of discharge ports. The two discharge ports are distributed on the left and right. Corresponding to the discharge ports, there is a pair of guide channels 4 distributed on the left and right on the pipe wall. The guide channels 4 are located above the baffle arm 13. The guide channels 4 are assembled from metal plates into an upward-facing U-shape. The end of the guide channel 4 is inclined downward so that the mud and sand flowing out of the discharge port can automatically slide down along the guide channel 4.
[0051] Reference Figure 4 , Figure 6 and Figure 7 On both the left and right sides of the platform 101, there are drainage holes 2. The drainage holes 2 face the area between the embankments on both sides of the sluice gate to ensure the correct landing point of the water source. Corresponding to the drainage holes 2, a sand collecting bucket 5 is placed on the platform 101. The sand collecting bucket 5 is not higher than the end of the guide channel 4. The top interface of the sand collecting bucket 5 corresponds to the discharge port at the end of the guide bucket to ensure that the silt falls accurately into the sand collecting bucket 5. The sand collecting bucket 5 is equipped with a water filtering structure. The water filtering structure is a conical filter screen cylinder 18. The opening of the filter screen cylinder 18 is centrally located at the bottom of the sand collecting bucket 5. The part directly corresponds to the drain hole 2, and the diameter of the circular opening matches the drain hole 2. Thus, the water filtered by the filter screen cylinder 18 will fall through the drain hole 2 into the water area between the two embankments on both sides of the gate. The filter screen cylinder 18 removes water from the silt, which can reduce the dilution of the silt and make the silt drier for reuse or treatment. The height of the top cone of the filter screen cylinder 18 is close to the top interface of the sand collection bucket 5 to ensure the filtration area of the filter screen cylinder 18. The bottom surface of the inner bucket of the sand collection bucket 5 is sloping to avoid water accumulation at the bottom of the inner bucket of the sand collection bucket 5.
[0052] Reference Figure 2 , Figure 3 and Figure 4 The sand-cleaning pipe 3 can be lifted upwards by the lifting mechanism to detach the lower sand-draining section from the sedimentation tank, so that the sand-cleaning pipe 3 can clean the silt in other sedimentation tanks. The lifting mechanism includes: a winch motor 14, lifting wheels 15, and lifting cables 16. The winch motor 14 is located on the right leg column 7. There is a pair of lifting wheels 15, which are respectively located on the front and rear sides of the sand-cleaning pipe 3. The rotation direction of the lifting wheels 15 is perpendicular to the gate opening. There are two lifting cables 16, which are arranged parallel to each other and are respectively located at the bottom of the two lifting wheels 15. The middle part of the lifting cable 16 The lifting cable 16 is in contact with the bottom wheel surface of the lifting wheel 15, and its middle part is concave to provide telescopic space for lifting the sand-cleaning pipe 3. The lifting cable 16 located in front of the sand-cleaning pipe 3 is pulled out from the winch motor 14, and the end of the lifting cable 16 is fixed on the left leg column 7 at the same height as the winch motor 14. The shaft of the winch motor 14 passes through the right leg column 7 and protrudes out. A winding wheel 17 is provided at the end of the shaft of the winch motor 14. One end of the lifting cable 16 located behind the sand-cleaning pipe 3 is wound around the winding wheel 17, and the other end is fixed to the left leg column 7. At the same height as the hoisting motor 14, to ensure the two lifting cables 16 are parallel, a wheel of the same specifications as the lifting wheel 15 is provided on the left leg column 7 where the lifting cables 16 are fixed. However, this wheel has a different function than the lifting wheel 15. Based on this, the stability of the sand-cleaning pipe 3's ascent is ensured by the two synchronously moving lifting cables 16. During actual operation, when the working position of the sand-cleaning pipe 3 needs to be adjusted, the hoisting motor 14 is started to tighten the lifting cables 16. The concave portion in the middle of the lifting cable 16 gradually rises to a horizontal state. As the lifting cables 16 tighten... During the process, the concave part in the middle of the lifting cable 16 will push the lifting wheel 15 upward, thereby causing the sand pumping part at the lower end of the sand cleaning pipe 3 to detach from the sedimentation tank. Then, the workbench 1 is moved to change the position of the sand cleaning pipe 3, moving it directly above another sedimentation tank. The lifting cable 16 is extended by the winch motor 14. At this time, the middle part of the lifting cable 16 begins to concave, and the lifting wheel 15 also descends. The sand cleaning pipe 3 also gradually falls due to its own weight, and the sand pumping part at its lower end will penetrate into the corresponding sedimentation tank below. The drive motor at the upper end of the sand cleaning pipe 3 is then started to carry out the mud and sand cleaning operation.
[0053] The implementation of this invention can effectively reduce the economic burden of cleaning sludge at gates, and it is fully applicable to the sedimentation tanks set before and after existing gates. It can be flexibly adjusted and used to effectively clean the sludge in the sedimentation tanks. The cleaning efficiency is fast, the work quality is high, and the use effect is excellent. Compared with the existing sand cleaning methods, it has greater application value.
[0054] Example 2 is basically the same as Example 1, except that it can quickly and correctly align the water drop point of the sand collection bucket 5 with the water drain hole 2. Because the end of the guide channel 4 is located above the interface of the sand collection bucket 5, the sand collection bucket 5 cannot be lifted vertically upwards. It is necessary to first move the sand collection bucket 5 to misalign it with the guide channel 4, eliminating the interference of the guide channel 4 on the sand collection bucket 5. Similarly, when placing the sand collection bucket 5, the influence of the guide channel 4 prevents the direct alignment of the water drop point of the sand collection bucket 5 with the water drain hole 2. Even if the guide channel 4 does not interfere with the sand collection bucket 5 being lowered, the workers cannot ensure that the water drop point of the sand collection bucket 5 directly aligns with the water drain hole 2. Further calibration of the positions of the water drop point of the sand collection bucket 5 and the water drain hole 2 is required, reducing work efficiency. Therefore, this embodiment needs to further solve the above problems. Specifically, refer to... Figure 2 , Figure 6 and Figure 7 The bottom of the sand collecting bucket 5 is equipped with a pair of high casters 19 and low casters 20. On both the left and right sides of the upper platform 101, directional grooves 21 matching the high casters 19 are provided along its length to accommodate two sand collecting buckets 5 corresponding to the two left and right distributed guide channels 4. The high casters 19 are located within the directional grooves 21 and can move within them. The movement path of the sand collecting bucket 5 can be predetermined through the cooperation of the high casters 19 and the directional grooves 21. An upwardly protruding limiting platform is provided in the middle of the platform 101. The final stopping position of the sand collection bucket 5 is determined by the limiting platform. Based on this, when the sand collection bucket 5 is pushed to the limiting platform, the water drop point of the sand collection bucket 5 can be correctly aligned with the water drop hole 2, which provides great convenience for the staff and also effectively improves the work efficiency of cleaning mud and sand. The low casters 20 are in contact with the upper surface of the high platform section 101. The low casters 20 are used to ensure the stability of the movement of the sand collection bucket 5 and to support the left and right sides of the sand collection bucket 5 to prevent it from tilting to one side and increasing the workload.
[0055] Example 3, based on Examples 1 and 2, further improves the flexibility and effectiveness of this device. Specifically, refer to... Figure 4 and Figure 5Feedback lights 22 are provided on the side of the supply plate 802 facing the sand-cleaning pipe 3, corresponding to the sedimentation tank. Multiple feedback lights 22 can be set according to the actual number of sedimentation tanks, ensuring that each feedback light 22 corresponds to one sedimentation tank. The feedback lights 22 are installed on the outer end of the spring block 23. The outer end of the spring block 23 is positioned flush with the outer side of the supply plate 802 by an elastic mechanism. This elastic mechanism includes a crossbar 25 and a compression spring 26. The crossbar 25 is located in a groove inside the side of the supply plate 802 corresponding to the sand-cleaning pipe 3. The compression spring 26 is fitted onto the crossbar 25. The inner end of the spring block 23 extends through the side wall of the supply plate 802 into its channel. A slider 27 is provided on the surface of the spring block 23. The slider 27 is fitted onto the crossbar 25 and slides along its body. One end of the compression spring 26 touches the slider 27. Based on this, the inner end of the spring block 23 will always be located within the channel of the supply plate 802 when not affected by external forces. The inner end face of the 3 is arc-shaped so that the leg column 7, which moves in the channel, pushes the spring block 23 outward. The positive and negative terminals of the feedback lamp 22 are located on the inner end face of the spring block 23. The leg column 7 has a receiving groove on the side facing the sand clearing pipe 3 that matches the inner end of the spring block 23. The receiving groove is equipped with a power supply 24, and the positive and negative plates of the power supply 24 are exposed in the receiving groove. When the inner end of the spring block 23 is completely inserted into the receiving groove, the positive and negative terminals of the feedback lamp 22 will contact the positive and negative plates of the power supply 24, thereby illuminating the feedback lamp 22. When the feedback lamp 22 is lit, the staff will know that the position of the sand clearing pipe 3 has been aligned with the sedimentation tank below. This method provides great convenience for the staff. When the water quality in the waters before and after the gate is turbid or when working at night, this implementation can ensure the normal operation of the silt cleaning operation without affecting the work progress, and effectively improve the use effect of this device.
