Description

Technical Field

[0001] This utility model relates to the field of hydraulic dam technology, and in particular to a hydraulic dam control drive device. Background Technology

[0002] Hydraulic dams are a new type of gate that uses hydraulic cylinders to control the movement of the gate, achieving the purpose of water storage and release in river dams. Compared with traditional hydraulic automatic gates, hydraulic dams have greater flexibility and precision, can more accurately control water levels, and better regulate water flow. At the same time, due to their hydraulic control system, the raising and lowering process of the gate is more stable, which can better protect the ecological environment of the river. Therefore, hydraulic dams have been widely used in irrigation, flood control, hydropower stations and other fields.

[0003] Chinese Patent CN220414158U discloses a hydraulic dam side water-stopping adjustment device, including a hydraulic dam side seat. First ball screws are rotatably connected to the bottom sides of the hydraulic dam side seat. Cylinders are fixedly installed on the bottom sides of one side wall of the hydraulic dam side seat. Sleeves are threadedly connected to the outer sides of the two first ball screws. A stirring paddle is fixedly connected to the outer ends of the two sleeves, which are away from the cylinders, through the hydraulic dam side seat. Sealing blocks are rotatably connected to the outer sides of the two sleeves. The two sealing blocks are slidably connected to the bottom of the hydraulic dam side seat. A groove is formed on the top of each of the two sealing blocks. A first slider is slidably connected inside each of the two grooves. The bottom of the first slider is fixedly connected to the end of the sealing block near the cylinder. This utility model facilitates the opening of the gate and extends the gate's service life.

[0004] However, the above-mentioned solutions cannot accurately control the opening and closing positions of the gate when using hydraulic dams, resulting in the gate not being in place or moving excessively, increasing operational risks. In addition, the rotation of the mixing paddle requires a large amount of power to drive it, especially when the sediment is thick, it needs to overcome greater resistance, which leads to increased energy consumption. Therefore, a hydraulic dam control drive device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the technical challenges of precisely controlling the opening and closing positions of gates when using hydraulic dams, which can lead to gates not being in position or moving excessively, and the need for significant power to drive the rotating agitator, especially when there is a thick layer of silt, requiring overcoming greater resistance, this application provides a hydraulic dam control drive device.

[0006] This utility model proposes a hydraulic dam control drive device, which includes a hydraulic dam base and a gate. The upper surface of the hydraulic dam base is provided with a moving mechanism, which includes a hydraulic cylinder. The extension and retraction of the piston rod of the hydraulic cylinder drives the gate to move.

[0007] The hydraulic dam base is equipped with a cleaning mechanism, which includes a drill bit. The rotation of the drill bit cleans the silt accumulated at the bottom of the gate.

[0008] Preferably, the moving mechanism further includes a slide bar, which is fixedly installed on the inner side wall of the top of the hydraulic dam base, and the gate is slidably sleeved on the outer surface of the slide bar, and the slide bar is made of stainless steel.

[0009] The above technical solution involves fixing the slide bar to the hydraulic dam base, and then sliding the gate to the slide bar, which fixes the gate without affecting its movement. The slide bar is made of stainless steel, which has good wear resistance and corrosion resistance, and its surface is polished to reduce the coefficient of friction, thereby reducing the impact on the movement of the gate.

[0010] Preferably, the hydraulic cylinder is fixedly installed on the inner side wall of the top of the hydraulic dam base, one end of the piston rod of the hydraulic cylinder is fixedly installed on the inner side wall of the top of the gate, and the gate is slidably inserted into the inner wall of the groove of the hydraulic dam base.

[0011] The above technical solution involves fixing the hydraulic cylinder to the hydraulic dam base and the gate to the dam. The hydraulic cylinder piston rod is also fixed to the gate. The hydraulic cylinder and oil pump are connected via hydraulic pipelines. The oil pump, as the power source, draws hydraulic oil from the oil tank and delivers it to the hydraulic cylinder through the hydraulic pipelines. By controlling the output flow and direction of the oil pump, the extension and retraction of the hydraulic cylinder piston rod can be adjusted, thereby driving the gate to move and controlling its opening and closing. The gate is slidably connected to the hydraulic dam base, fixing it without affecting its movement, thus ensuring the stability of the gate's movement.

[0012] Preferably, a sealing strip is fixedly bonded to the outer surface of the hydraulic dam base, the sealing strip being made of perfluororubber, and a distance measuring sensor is fixedly installed in the groove at the top of the hydraulic dam base.

[0013] The above technical solution involves fixing the hydraulic dam base to the sealing strip. The sealing strip is made of perfluororubber, which has excellent chemical corrosion resistance, high temperature resistance, weather resistance, and low coefficient of friction. These properties enable the sealing strip to maintain a good sealing effect in various harsh environments, while reducing resistance to the movement of the gate. The hydraulic dam base is also fixed to a distance sensor, which monitors the movement of the gate, thereby achieving precise control of the gate position and preventing the gate from being out of position or moving excessively.

[0014] Preferably, the cleaning mechanism further includes a threaded sleeve, one of which is rotatably connected to the bottom groove of the hydraulic dam base via a bearing. A motor is fixedly installed in the bottom groove of the hydraulic dam base, and the output shaft of the motor is fixedly installed to one end of the other threaded sleeve. The threaded sleeve is made of polytetrafluoroethylene.

[0015] Through the above technical solution, one threaded sleeve is rotatably connected to the hydraulic dam base via a bearing to ensure the stability of the threaded sleeve rotation. The hydraulic dam base is fixedly installed to the motor for fixation. The output shaft of the motor is fixedly installed to another threaded sleeve to drive the other threaded sleeve to rotate. The threaded sleeve is made of polytetrafluoroethylene, which has excellent self-lubricating properties, chemical corrosion resistance, high temperature resistance and low coefficient of friction. These characteristics make the threaded sleeve have low frictional resistance and good wear resistance when rotating.

[0016] Preferably, one end of the other threaded sleeve is driven by a synchronous pulley via a synchronous belt to rotate one of the threaded sleeves. The outer surface of the threaded sleeve has a waist hole, and a screw is slidably connected to the inner wall of the threaded sleeve. The screw is made of titanium alloy, and a round rod is fixedly installed on one end of the screw. The outer surface of the round rod is slidably connected to the inner wall of the waist hole.

[0017] Through the above technical solution, the synchronous pulley at one end of the other threaded sleeve drives the threaded sleeve to rotate through the synchronous belt, so that both threaded sleeves rotate. The threaded sleeve is slidably connected to the screw, and the round rod is slidably connected to the waist hole. This drives the screw to rotate without affecting its lifting and lowering. The screw is made of titanium alloy, which has good wear resistance, reducing the wear between the screw and the threaded sleeve.

[0018] Preferably, the inner wall of the bottom groove of the hydraulic dam base is threadedly connected to the outer surface of the screw, the drill bit is fixedly installed at the other end of the screw, and the drill bit is made of high-speed steel.

[0019] The above technical solution uses a hydraulic dam base connected to a screw rod via a threaded connection to limit the screw rod's movement, allowing it to rotate and rise. A drill bit is fixedly installed to the screw rod, and the rotation of the screw rod drives the drill bit to rotate. The drill bit is made of high-speed steel, which has high hardness, high wear resistance, and good cutting performance, making it suitable for cleaning hard materials such as silt. The drill bit is conical in shape and has threaded grooves. The conical design of the drill bit facilitates drilling into and breaking up silt, improving cleaning efficiency. The threaded grooves help to discharge the broken silt, preventing blockages and improving the cleaning effect.

[0020] The beneficial effects of this utility model are as follows: 1. By setting up a moving mechanism, the gate is moved. The extension and retraction of the hydraulic cylinder piston rod drives the gate to move, controlling its opening and closing. The sealing strip is made of perfluororubber, which has excellent chemical corrosion resistance, high temperature resistance, weather resistance and low coefficient of friction. These characteristics enable the sealing strip to maintain a good sealing effect in various harsh environments, while reducing resistance to the movement of the gate. The distance sensor monitors the movement of the gate, thereby realizing precise control of the gate position and avoiding the gate from being out of position or moving excessively. This solves the technical problem of not being able to accurately control the opening and closing position of the gate when using a hydraulic dam, which leads to the gate being out of position or moving excessively, increasing the operational risk.

[0021] 2. By setting up a cleaning mechanism, the silt accumulated at the bottom of the gate is cleaned. The motor drives another threaded sleeve to rotate, and the synchronous pulley at one end of the other threaded sleeve drives the other threaded sleeve to rotate through the synchronous belt. The threaded sleeve is slidably connected to the screw, and the round rod is slidably connected to the waist hole. While driving the screw to rotate, it does not affect its lifting and lowering. The hydraulic dam base is threadedly connected to the screw, which limits the screw and allows it to rotate and lift. The rotation of the screw drives the drill bit to rotate, thereby cleaning the silt. This solves the technical problem that when using a hydraulic dam, the rotation of the mixing paddle requires a large amount of power, especially when the silt is thick, it is necessary to overcome greater resistance, which leads to increased energy consumption.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 A hydraulic dam control drive device includes a hydraulic dam base 1 and a gate 11. A moving mechanism is provided on the upper surface of the hydraulic dam base 1. The moving mechanism includes a hydraulic cylinder 3. The extension and retraction of the piston rod of the hydraulic cylinder 3 drives the gate 11 to move.

[0026] To reduce the impact of the sliding rod 2 on the movement of the gate 11, the moving mechanism also includes the sliding rod 2. The sliding rod 2 is fixedly installed on the inner side wall of the top of the hydraulic dam base 1. The gate 11 is slidably sleeved on the outer surface of the sliding rod 2. The sliding rod 2 is made of stainless steel. It is fixed to the hydraulic dam base 1 by the sliding rod 2, and the gate 11 is slidably sleeved on the sliding rod 2, which fixes it without affecting its movement. The material of the sliding rod 2 is stainless steel, which has good wear resistance and corrosion resistance. The surface is polished, which can reduce the coefficient of friction, thereby reducing the impact on the movement of the gate 11.

[0027] To ensure the stability of the gate 11's movement, the hydraulic cylinder 3 is fixedly installed on the inner side wall of the top of the hydraulic dam base 1. One end of the piston rod of the hydraulic cylinder 3 is fixedly installed on the inner side wall of the top of the gate 11. The gate 11 is slidably inserted into the inner wall of the groove of the hydraulic dam base 1. The hydraulic cylinder 3 is fixedly installed to the hydraulic dam base 1, and the gate 11 is fixedly installed to the hydraulic cylinder 3. The hydraulic cylinder 3 is connected to the oil pump through a hydraulic pipeline. The oil pump, as a power source, draws hydraulic oil from the oil tank and delivers it to the hydraulic cylinder 3 through the hydraulic pipeline. By controlling the output flow and direction of the oil pump, the extension and retraction of the piston rod of the hydraulic cylinder 3 can be adjusted, thereby driving the gate 11 to move and controlling its opening and closing. The gate 11 is slidably inserted into the hydraulic dam base 1, which fixes it without affecting its movement, so as to ensure the stability of the gate 11's movement.

[0028] To prevent the gate 11 from being misaligned or moving excessively, a sealing strip 4 is fixedly bonded to the outer surface of the hydraulic dam base 1. The sealing strip 4 is made of perfluororubber. A distance sensor 41 is fixedly installed in the groove at the top of the hydraulic dam base 1. The sealing strip 4 is fixedly bonded to the hydraulic dam base 1. The sealing strip 4 is made of perfluororubber, which has excellent chemical corrosion resistance, high temperature resistance, weather resistance and low coefficient of friction. These characteristics enable the sealing strip 4 to maintain a good sealing effect in various harsh environments, while reducing the resistance to the movement of the gate 11. The distance sensor 41 is fixedly installed to the hydraulic dam base 1 and monitors the movement of the gate 11, thereby achieving precise control of the position of the gate 11 and preventing the gate 11 from being misaligned or moving excessively.

[0029] By setting up a moving mechanism, the gate 11 is moved. The extension and retraction of the piston rod of the hydraulic cylinder 3 drives the gate 11 to move, controlling its opening and closing. The sealing strip 4 is made of perfluororubber, which has excellent chemical corrosion resistance, high temperature resistance, weather resistance and low coefficient of friction. These characteristics enable the sealing strip 4 to maintain a good sealing effect in various harsh environments, while reducing the resistance to the movement of the gate 11. The distance sensor 41 monitors the movement of the gate 11, thereby realizing precise control of the position of the gate 11, avoiding the gate 11 from being out of position or moving excessively. This solves the technical problem that when using a hydraulic dam, it is impossible to accurately control the opening and closing position of the gate 11, resulting in the gate 11 being out of position or moving excessively, which increases the operational risk.

[0030] In order to clean the silt accumulated at the bottom of the gate 11, a cleaning mechanism is installed inside the hydraulic dam base 1. The cleaning mechanism includes a drill bit 7, and the rotation of the drill bit 7 cleans the silt accumulated at the bottom of the gate 11.

[0031] To minimize frictional resistance during rotation, the cleaning mechanism also includes a threaded sleeve 5. One threaded sleeve 5 is rotatably connected to the bottom groove of the hydraulic dam base 1 via a bearing. A motor 51 is fixedly installed in the bottom groove of the hydraulic dam base 1. The output shaft of the motor 51 is fixedly installed to one end of another threaded sleeve 5. The threaded sleeve 5 is made of polytetrafluoroethylene (PTFE). The rotatable connection between the threaded sleeve 5 and the hydraulic dam base 1 via the bearing ensures the stability of the rotation of the threaded sleeve 5. The motor 51 is fixedly installed to the hydraulic dam base 1 for fixation. The output shaft of the motor 51 is fixedly installed to the other threaded sleeve 5 to drive the other threaded sleeve 5 to rotate. The threaded sleeve 5 is made of PTFE, which has excellent self-lubricating properties, chemical corrosion resistance, high temperature resistance, and low coefficient of friction. These characteristics result in low frictional resistance and good wear resistance during rotation of the threaded sleeve 5.

[0032] To reduce wear between the screw 61 and the threaded sleeve 5, a timing pulley at one end of another threaded sleeve 5 drives the threaded sleeve 5 to rotate via a timing belt. A slotted hole 6 is formed on the outer surface of the threaded sleeve 5. The screw 61 is slidably connected to the inner wall of the threaded sleeve 5. The screw 61 is made of titanium alloy. A round rod 62 is fixedly mounted on one end of the screw 61, and the outer surface of the round rod 62 is slidably connected to the inner wall of the slotted hole 6. A timing pulley at one end of the other threaded sleeve 5 drives the threaded sleeve 5 to rotate via a timing belt. The threaded sleeve 5 is slidably connected to the screw 61, while the round rod 62 is slidably connected to the slotted hole 6. This allows the screw 61 to rotate without affecting its lifting and lowering. The screw 61 is made of titanium alloy, which has good wear resistance, thus reducing wear between the screw 61 and the threaded sleeve 5.

[0033] To improve the cleaning effect, the inner wall of the bottom groove of the hydraulic dam base 1 is threadedly connected to the outer surface of the screw 61. The drill bit 7 is fixedly installed at the other end of the screw 61. The drill bit 7 is made of high-speed steel. The hydraulic dam base 1 is threadedly connected to the screw 61 to limit the screw 61 and allow it to rotate and rise. The drill bit 7 is fixedly installed to the screw 61. The rotation of the screw 61 drives the drill bit 7 to rotate. The drill bit 7 is made of high-speed steel, which has high hardness, high wear resistance and good cutting performance. It is suitable for cleaning hard materials such as silt. The drill bit 7 is conical in shape and has threaded grooves. The conical design of the drill bit 7 is conducive to drilling and breaking up silt, improving the cleaning efficiency. The threaded groove design helps to discharge the broken silt, prevent blockage and improve the cleaning effect.

[0034] By setting up a cleaning mechanism, the silt accumulated at the bottom of the gate 11 is cleaned. The motor 51 drives another threaded sleeve 5 to rotate. One end of the other threaded sleeve 5 is driven by a synchronous pulley through a synchronous belt. The threaded sleeve 5 is slidably connected to the screw 61. At the same time, the round rod 62 is slidably connected to the waist hole 6, so that the screw 61 can be rotated without affecting its lifting and lowering. The hydraulic dam base 1 is threadedly connected to the screw 61, which limits the screw 61 and allows it to rotate and lift. The rotation of the screw 61 drives the drill bit 7 to rotate, thereby cleaning the silt. This solves the technical problem that when using a hydraulic dam, the rotation of the stirring paddle requires a large amount of power, especially when the silt is thick, it is necessary to overcome greater resistance, which leads to increased energy consumption.

[0035] Working principle: When it is necessary to clean the silt accumulated in front of the gate 11, the motor 51 is started to drive the threaded sleeve 5 fixedly installed with its output shaft to rotate. One end of the threaded sleeve 5 is driven by a synchronous pulley to drive the other threaded sleeve 5 to rotate through a synchronous belt. The rotation of the threaded sleeve 5 drives the screw 61 slidably connected to it to rotate and rise in the groove of the threaded hydraulic dam base 1. The round rod 62 fixedly installed on the screw 61 is slidably connected to the inner wall of the waist hole 6 opened on the outer surface of the threaded sleeve 5, which further ensures the stability of the screw 61 when rotating, and does not affect its lifting and lowering movement. The rotation and lifting of the screw 61 drives the drill bit 7 to rotate and rise. The conical design of the drill bit 7 is conducive to drilling and breaking the silt. The design of the threaded groove on it helps to discharge the broken silt, prevent blockage, and improve the cleaning effect. When it is necessary to control the movement of the gate 11, the hydraulic cylinder 3 is connected to the oil pump through a hydraulic pipeline. The oil pump, as a power source, draws hydraulic oil from the oil tank and delivers it to the hydraulic cylinder 3 through the hydraulic pipeline. By controlling the output flow and direction of the oil pump, the extension and retraction of the piston rod of the hydraulic cylinder 3 can be adjusted, thereby driving the gate 11 to move on the sliding sleeve 2 and the sliding plug-in hydraulic dam base 1. The distance sensor 41 monitors the movement of the gate 11, thereby achieving precise control of the position of the gate 11 and avoiding the gate 11 from being out of position or moving excessively. The sealing strip 4 on the hydraulic dam base 1 prevents water leakage when the gate 11 is closed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
