Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically a lifting water gate for water conservancy projects. Background Technology

[0002] Water conservancy projects are constructed to eliminate water hazards and develop and utilize water resources. In water conservancy projects, gate facilities are an indispensable part of the infrastructure. As an important type of gate, the lift gate is widely used in various fields of water conservancy projects. Its main function is to close and open the water discharge channel, and to regulate the water level by raising and lowering the gate, thereby intercepting water flow, controlling water level, regulating flow, and discharging sediment or floating debris. The design and use of this type of gate greatly improves the management efficiency and operational safety of water conservancy projects.

[0003] However, although lift gates play an important role in water conservancy projects, some problems have also been exposed in practical applications. In particular, when there is a lot of floating garbage in the river, once the gate is opened, this floating garbage will be carried away by the water flow. This not only increases the difficulty of cleaning the downstream river channel, but may also damage the river's ecological environment. Therefore, in order to address the above problems, it is necessary to improve and optimize the existing lift gates to enhance their stability and durability, reduce the impact of garbage on the gates, and ensure the normal operation of water conservancy projects and the safety of the ecological environment. Summary of the Invention

[0004] To address the problem mentioned in the background art that floating garbage in rivers flows with the water when the gate is opened, increasing the difficulty of cleaning and damaging the ecological environment, the present invention provides a lifting hydraulic gate for water conservancy projects.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lifting hydraulic gate for water conservancy projects, comprising a gate base, a gate top cover fixedly installed on the top of the gate base, two hydraulic presses fixedly installed on the bottom of the gate top cover, a gate fixedly installed on the bottom of each of the two hydraulic presses, the gate being slidably connected to the gate base, a rectangular box fixedly installed on the bottom front of the gate base, two sets of transmission mechanisms being provided inside the rectangular box, and two sets of cleaning mechanisms being provided inside the gate base;

[0006] The transmission mechanism includes a transmission component one and a transmission component two. The transmission component two includes two fixed blocks two fixedly installed inside the rectangular box. A rotating rod two is rotatably installed on the fixed blocks two. A worm gear is fixedly sleeved on the outer wall of the rotating rod two. One end of the rotating rod two extends out of the outer side of the corresponding fixed block two. An installation groove is opened in the front side wall of the gate base. The installation groove is connected to the rectangular box. A worm is rotatably installed inside the rectangular box. The worm meshes with the worm gear.

[0007] Preferably, the transmission assembly two includes a fixed block one fixedly installed on the front of the gate base, a rotating rod one rotatably installed on the bottom of the fixed block one, and the bottom end of the rotating rod one extends into the rectangular box and is fixedly connected to the worm gear.

[0008] Preferably, five sets of fan blades are fixedly installed on the outer wall of the rotating rod, each set of fan blades consisting of four blades, all of which are distributed in a circular array at equal distances around the rotating rod as the axis.

[0009] Preferably, the fixing block is L-shaped, with one end fixedly connected to the gate base and the other end rotatably connected to the rotating rod.

[0010] Preferably, a rotating rod four is rotatably installed inside the mounting groove, and pulleys are fixedly sleeved on the outer walls of both the rotating rod four and the rotating rod two, and are connected by a synchronous belt.

[0011] Preferably, the cleaning mechanism includes two rotating rods three rotatably mounted on the inner wall of the gate base. One end of each rotating rod three extends into the mounting groove and is rotatably connected to the mounting groove. Circular rollers are fixedly sleeved on the outer walls of the two rotating rods three respectively, and both circular rollers are connected by a conveyor belt.

[0012] Preferably, a plurality of slag-collecting plates are fixedly installed on the outer wall of the conveyor belt, and the plurality of slag-collecting plates are designed in an L-shape and distributed at equal intervals on the outer wall of the conveyor belt.

[0013] Preferably, pulleys are respectively provided on the outer walls of the corresponding rotating rod three and rotating rod four, and they are connected by synchronous belt two.

[0014] Preferably, two filter plates are fixedly installed inside the gate base. The two filter plates are inclined and have an "eight" shape. Slag discharge troughs are opened on both sides of the gate base.

[0015] Preferably, a filter plate is slidably installed on the outer wall of the back side of the gate base, and the area of ​​the filter plate is greater than the area of ​​the gate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention utilizes a transmission mechanism to drive the rotating rod and fan blades to rotate using the power of the water flow itself. The power is then transmitted to subsequent transmission components and the cleaning mechanism via a worm gear transmission. This not only saves additional energy input and achieves efficient energy utilization, but also ensures the reliability of the transmission. The worm gear mechanism has advantages such as a large transmission ratio, compact structure, and strong load-bearing capacity, and can stably transmit power from the water flow to the cleaning mechanism, ensuring the smooth operation of the entire system.

[0018] This invention achieves automated cleaning of waste inside the gate foundation through the cooperation of a rotating rod, a circular roller, a conveyor belt, and a slag-collecting plate. The slag-collecting plate, moving with the conveyor belt, continuously and efficiently collects and lifts the waste from the bottom of the gate foundation, bringing it to the highest point before it slides down and is discharged from the gate foundation through structures such as the slag discharge trough. This greatly improves cleaning efficiency, reduces the frequency and difficulty of manual cleaning, and effectively avoids pollution of the gate foundation and downstream river channels by waste, protecting the safety of the ecological environment. At the same time, the inclined design of the filter plate and the setting of the slag discharge trough further enhance the waste treatment effect, ensuring effective cleaning and discharge of waste.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 9 As shown, the present invention provides a lifting hydraulic gate for water conservancy projects, including a gate base 1, a gate top cover 2 fixedly installed on the top of the gate base 1, two hydraulic presses 3 fixedly installed on the bottom of the gate top cover 2, a gate 4 fixedly installed on the bottom of each of the two hydraulic presses 3, the gate 4 being slidably connected to the gate base 1, a rectangular box 101 fixedly installed on the bottom of the front side of the gate base 1, two sets of transmission mechanisms being provided inside the rectangular box 101, and two sets of cleaning mechanisms being provided inside the gate base 1;

[0031] The transmission mechanism includes a transmission component one and a transmission component two. The transmission component two includes two fixed blocks 6 fixedly installed inside the rectangular box 101. A rotating rod 601 is rotatably installed on the fixed blocks 6. A worm gear 601 is fixedly sleeved on the outer wall of the rotating rod 601. One end of the rotating rod 601 extends out of the outer side of the corresponding fixed block 6. An installation groove 102 is opened in the front side wall of the gate base 1. The installation groove 102 is connected to the rectangular box 101. A worm 502 is rotatably installed inside the rectangular box 101. The worm 502 meshes with the worm gear 6011.

[0032] The above scheme is adopted: by setting up a transmission mechanism and a cleaning mechanism, when water flows into the gate base 1, it first contacts the transmission component 2 inside the rectangular box 101 fixedly installed at the bottom of the front of the gate base 1. The fan blade 5011 in the transmission component 2 rotates under the action of the water flow, driving the rotating rod 1 501 and the worm gear 502 fixedly connected to it to rotate. The worm gear 502 drives the worm wheel 6011 and the rotating rod 2 601 to rotate. The rotation of the rotating rod 2 601 can transmit power to the cleaning mechanism. The circular roller 701 and the conveyor belt 7011 fixedly sleeved on the rotating rod 3 7 are connected by the rotation of the rotating rod 3 7. The conveyor belt 7011, which is fixedly installed on the outer wall of the conveyor belt 7011, moves accordingly, picking up and lifting the garbage at the bottom of the gate base 1. The garbage is carried to the highest point of the conveyor belt 7011 and then slides down, being discharged from the gate base 1 through the slag discharge trough 103 and other structures. The water flow drives the fan blade 5011 to rotate, and the power is transmitted to other components through the worm gear 502 and worm wheel 6011, realizing the effective use of energy and the reliability of transmission. The cleaning mechanism can continuously and efficiently clean the garbage in the gate base 1, keeping the water conservancy facilities clean and unobstructed.

[0033] By setting up a transmission mechanism, the rotating rod 501 and the fan blade 5011 are driven to rotate by the power of the water flow itself. Then, the power is transmitted to the subsequent transmission components and cleaning mechanism through the worm gear 502 and the worm wheel 6011. This not only saves additional energy input and realizes the efficient use of energy, but also ensures the reliability of the transmission. The worm gear 502 and the worm wheel 6011 have the advantages of large transmission ratio, compact structure and strong load-bearing capacity. They can stably transmit power from the water flow to the cleaning mechanism, ensuring the smooth operation of the entire system.

[0034] Through the coordination of the rotating rod 7, the circular roller 701, the conveyor belt 7011, and the slag-collecting plate 70111, the automated cleaning of garbage inside the gate foundation 1 is realized. The slag-collecting plate 70111, along with the movement of the conveyor belt 7011, can continuously and efficiently collect and lift the garbage at the bottom of the gate foundation 1, bring it to the highest point and then slide it down, and it is discharged from the gate foundation through the slag discharge trough 103 and other structures, which greatly improves the cleaning efficiency, reduces the frequency and difficulty of manual cleaning, and effectively avoids the pollution of the gate foundation 1 and the downstream river channel by garbage, thus protecting the safety of the ecological environment. At the same time, the inclined design of the filter plate 105 and the setting of the slag discharge trough 103 further enhance the garbage treatment effect, ensuring the effective cleaning and discharge of garbage.

[0035] like Figures 3 to 5 As shown, the transmission assembly 2 includes a fixed block 5 fixedly installed on the front of the gate base 1. A rotating rod 501 is rotatably installed on the bottom of the fixed block 5. The bottom end of the rotating rod 501 extends into the rectangular box 101 and is fixedly connected to the worm gear 502. Five sets of fan blades 5011 are fixedly installed on the outer wall of the rotating rod 501. Each set of fan blades 5011 consists of four blades and is distributed in a circular array at equal distances around the rotating rod 501 as the axis. The fixed block 5 is L-shaped. One end of the fixed block 5 is fixedly connected to the gate base 1, and the other end is rotatably connected to the rotating rod 501.

[0036] The above solution involves setting up a rotating rod 501. Water flows through the rotating rod 501 and contacts the fan blades 5011 on it. Since the fan blades 5011 are evenly distributed in a circular array around the rotating rod 501, the water flow acts uniformly on each blade, generating rotational torque. Driven by the water flow, the rotating rod 501 begins to rotate. Because the bottom end of the rotating rod 501 is fixedly connected to the worm gear 502, the rotation of the rotating rod 501 drives the worm gear 502 to rotate as well. The worm gear 502 transmits power to subsequent transmission components and cleaning mechanisms. The final drive conveyor belt 7011 and the slag-collecting plate 70111 move to clean up the garbage in the gate base 1; the rotation of the rotating rod 501 and the fan blade 5011 is driven by the power of the water flow itself, without the need for additional energy input, thus realizing the efficient use of energy. The fixed block 5 is designed in an L shape, with one end fixedly connected to the gate base 1 and the other end rotatably connected to the rotating rod 501, ensuring the stable rotation of the rotating rod 501. The fan blades 5011 are distributed in a circular array at equal intervals around the rotating rod 501 as the axis. This layout can maximize the use of the power of the water flow and improve the rotation efficiency.

[0037] like Figure 7 As shown, a rotating rod 9 is rotatably installed inside the mounting groove 102. Both the rotating rod 9 and the outer wall of the rotating rod 601 are fixedly fitted with pulleys and are connected by a synchronous belt 8.

[0038] The above scheme is adopted: the pulley on the second rotating rod 601 is connected to the pulley on the fourth rotating rod 9 through the synchronous belt 8. When the pulley on the second rotating rod 601 rotates, it will drive the synchronous belt 8 and the pulley on the fourth rotating rod 9 to rotate, thereby causing the fourth rotating rod 9 to start rotating. Through the transmission connection between the pulley and the synchronous belt 8, the efficient power transmission from water flow drive to cleaning mechanism movement is realized, reducing energy loss.

[0039] like Figures 5 to 7 As shown, the cleaning mechanism includes two rotating rods 7 rotatably mounted on the inner wall of the gate base 1. One end of each rotating rod 7 extends into the mounting groove 102 and is rotatably connected to the mounting groove 102. Circular rollers 701 are fixedly sleeved on the outer walls of the two rotating rods 7. Both rollers 701 are connected by a conveyor belt 7011. Several slag-collecting plates 70111 are fixedly mounted on the outer wall of the conveyor belt 7011. The slag-collecting plates 70111 are L-shaped and evenly distributed on the outer wall of the conveyor belt 7011. Pulleys are respectively provided on the outer walls of the corresponding rotating rods 7 and 9 and are connected by a synchronous belt 10.

[0040] The above scheme is adopted as follows: The rotation of the drive rod 501 is transmitted through a series of transmission mechanisms to the drive rod 7. The rotation of the drive rod 7 drives the rotation of the circular roller 701 on its outer wall. Since the two circular rollers 701 are connected by a conveyor belt 7011, the rotation of the circular rollers 701 drives the conveyor belt 7011 to start moving. Several L-shaped slag-collecting plates 70111 are fixedly installed on the outer wall of the conveyor belt 7011. The slag-collecting plates 70111 move with the movement of the conveyor belt 7011. When they contact the slag at the bottom of the gate base 1... When garbage is collected, it is lifted up by the conveyor belt 7011. As the garbage collection plate 70111 and the conveyor belt 7011 continue to move, the collected garbage is carried to the highest point of the conveyor belt 7011. Due to gravity, the garbage slides off the garbage collection plate 70111 and is discharged from the gate base 1 through the slag discharge trough 103. The entire cleaning mechanism is driven by the power of the water flow, which saves energy and improves cleaning efficiency. Timely cleaning of garbage in the gate base 1 helps to reduce water pollution and ecological damage and protect the safety of the water environment.

[0041] like Figures 1 to 2 As shown, two filter plates 105 are fixedly installed inside the gate base 1. The two filter plates 105 are inclined and have an "eight" shape. Slag discharge troughs 103 are opened on both sides of the gate base 1. A filter plate 104 is slidably installed on the outer wall of the back of the gate base 1. The area of ​​the filter plate 104 is larger than the area of ​​the gate 4.

[0042] The above scheme is adopted: by setting two filter plates 105 and arranging them in a figure-eight shape, the water flow can be guided more effectively and impurities in the water can be filtered out. The garbage is transported to the bottom of both sides of the gate base 1 and discharged from the gate base 1 through the slag discharge trough 103.

[0043] High-efficiency filtration: The figure-eight arrangement of filter plate 2105 not only increases the filtration area but also improves the filtration efficiency, allowing water to flow more smoothly and making full use of the space inside gate base 1. This satisfies the needs of filtration and waste disposal while avoiding unnecessary space waste.

[0044] Working principle and usage process of this invention:

[0045] First, start the two hydraulic presses 3. Through the contraction action of the output shaft of the hydraulic presses 3, the gate 4 is moved upward smoothly and quickly, creating conditions for the smooth entry of water. As the gate 4 opens, the water begins to flow into the gate base 1, allowing it to flow out through the filter plate 104.

[0046] Before the water flows into the gate base 1, it first contacts the fan blades 5011 on the outer wall of the two rotating rods 501. The fan blades 5011 utilize the kinetic energy of the water flow to drive the rotating rod 501 and the worm gear 502 connected to it to rotate. Through the meshing of the worm gear 502 and the worm wheel 6011, the worm wheel 6011 and the rotating rod 601 on it are further driven to rotate. Subsequently, through the transmission of the synchronous belt 8 and the synchronous belt 10, the rotational power of the rotating rod 601 is transmitted to the rotating rod 9 and the corresponding rotating rod 7 and the roller 701. Finally, they jointly drive the conveyor belt 7011 to move.

[0047] By setting up slag-collecting plates 70111, when the bottom slag-collecting plates 70111 move upward with the movement of the conveyor belt 7011, they can effectively contact and collect the garbage located in the gate base 1. As the conveyor belt 7011 continues to move, after the slag-collecting plates 70111 and the garbage on them pass the highest point, the original top becomes the bottom. Under the action of gravity, the garbage naturally falls onto the filter plate 105, realizing the automatic collection and separation of garbage, which greatly reduces the burden of manual cleaning.

[0048] Finally, through the inclined design of the filter plate 105 and the ingenious setting of the slag discharge trough 103, the garbage was successfully discharged from the gate base 1 after undergoing water filtration treatment, ensuring effective garbage removal and avoiding pollution of the gate base 1 and downstream river channel by the garbage, thereby protecting the safety of the ecological environment.
