[0002] This utility model relates to the field of dam gate cleaning technology, specifically a dam gate obstacle clearing arm mechanism. Background Technology

[0003] Dam gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic dam structures and are mainly used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris. Because hydraulic gates are in constant contact with water, impurities and floating debris in the water easily adhere to their surfaces.

[0004] Chinese utility model patent with publication number CN215236635U discloses a cleaning device for a hydraulic dam gate, including a base plate and a pushing mechanism disposed on the base plate; the pushing mechanism includes a sliding table, a sliding block, a pushing hydraulic cylinder, a pushing hydraulic rod, and a lifting assembly disposed above the sliding block. The sliding table is disposed on the upper surface of the base plate and is movably connected to the sliding block, and the sliding block slides on the sliding table. The pushing hydraulic cylinder is mounted on the upper surface of the base plate, and its output end is connected to one end of the pushing hydraulic rod, and the other end of the pushing hydraulic rod is connected to one side surface of the sliding block.

[0005] The above solution facilitates the cleaning of impurities and stains on the gate surface by using the coordination of hydraulic cylinders, hydraulic rods, lifting hydraulic cylinders, and hydraulic rods.

[0032] Example 1

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the operating principle of the device and the main connection relationships of each component are further explained below in conjunction with specific embodiments.

[0034] Please see Figures 1-3This utility model provides a technical solution: a dam gate obstacle clearing arm mechanism, including a collection bucket 1, which is L-shaped. A movable arm 3 is movably installed inside one end of the collection bucket 1 through an adjustment mechanism. The adjustment mechanism includes a mounting groove 12, which is equidistantly opened inside one end of the collection bucket 1. Lifting drive mechanisms are provided on both sides of the collection bucket 1. The lifting drive mechanism includes a fixing block 6, which is symmetrically fixed on both sides of the top of the collection bucket 1. By rotating and adjusting the movable arm 3, it is convenient to move the floating objects, so that the floating objects enter the interior of the collection bucket 1 and are collected.

[0035] In this embodiment, a fixed plate 14 is fixedly installed at the bottom of one end of the collection hopper 1. A rotating rod 4 is rotatably installed inside the fixed plate 14. The movable arm 3 is fixedly installed on the rotating rod 4 at equal intervals. The top end of the movable arm 3 is movably disposed inside the mounting groove 12. The adjustment mechanism also includes a submersible electro-hydraulic push rod 10. One end of the submersible electro-hydraulic push rod 10 is movably installed on one side of the bottom of the collection hopper 1 through a rotating shaft 11. The piston rod 13 inside the submersible electro-hydraulic push rod 10 is movably connected to the bottom end of the middle movable arm 3 through a rotating shaft 15. The submersible electro-hydraulic push rod 10 drives the movable arm 3 to rotate inside the mounting groove 12, which facilitates the collection of floating objects into the inside of the collection hopper 1.

[0036] In this embodiment, side plates 2 are symmetrically fixedly installed on both sides of the top of the bottom end of the collecting hopper 1. Movable arms 3 are arranged between the side plates 2. Water permeable holes are opened inside the collecting hopper 1 and the side plates 2. The lifting drive mechanism also includes a screw 8. The screw 8 is screwed into the inside of the fixing block 6 through a screw hole. A servo motor 7 is provided at the top of the screw 8. The output shaft of the servo motor 7 is fixedly connected to the top of the screw 8. Water inside the collecting hopper 1 can be discharged through the water permeable holes, leaving floating objects inside the collecting hopper 1. The servo motor 7 drives the screw 8 to rotate, which facilitates the lifting and lowering of the collecting hopper 1 through the screw connection between the screw 8 and the fixing block 6.

[0037] In this embodiment, a shovel plate 5 is fixedly installed at the bottom of the collection bucket 1 on one side corresponding to the submersible electro-hydraulic push rod 10, and a gate body 9 is installed on one side of the collection bucket 1. The shovel plate 5 is attached to one side of the gate body 9. When the collection bucket 1 descends, it can drive the shovel plate 5 to clean the debris on the surface of the gate body 9.

[0038] When using the dam gate clearing arm mechanism, the servo motor 7 is started, which drives the screw 8 to rotate. The screw 8, through the screw hole, drives the fixing block 6 to descend. The fixing block 6 drives the collection bucket 1 to descend. The servo motor 7 is fixedly installed on the dam, so that the lifting and lowering of the mechanism is not affected. The collection bucket 1 drives the shovel plate 5 to descend, and the shovel plate 5 removes debris from the surface of the gate body 9. It is not necessary to wait for the dry season, and the gate body 9 can be cleaned at any time, which is convenient. The collection bucket 1 and the movable arm 3 are submerged in water, and the submersible electro-hydraulic push rod 10 is started. The submersible electro-hydraulic push rod 10 drives the movable arm 3 to rotate downward, so that the top of the movable arm 3 rotates out from the inside of the mounting groove 12. After the movable arm 3 is flattened, the collection bucket 1 is driven to rise by the servo motor 7, screw 8, fixing block 6, etc. At the same time, the movable arm 3 is driven to rotate in the opposite direction by the submersible electro-hydraulic push rod 9, which can collect floating objects in the water into the inside of the collection bucket 1, which is convenient for collecting floating objects and prevents them from adhering to the surface of the gate body, which is highly practical.

[0039] Example 2

[0040] Please see Figures 1-3 The specific connection and positional relationships of this device are further described in this embodiment as follows:

[0041] A dam gate clearing arm mechanism includes a collection bucket 1, with side plates 2 symmetrically fixed to the inner walls on both sides of the collection bucket 1; multiple mounting slots 12 are provided inside one end of the collection bucket 1; the other side of the collection bucket 1 is connected to the gate body 9; a shovel plate 5 is fixedly provided on one side of the bottom of the collection bucket 1, and the shovel plate 5 is closely connected to one side of the gate body 9; multiple fixing blocks 6 are symmetrically fixed to the outer walls on both sides of the top of the collection bucket 1.

[0042] One side of the bottom of the collecting hopper 1 is movably connected to one end of the submersible electro-hydraulic actuator 10 via a pivot 11. The piston rod 13 of the submersible electro-hydraulic actuator 10 is movably connected to the bottom pivot holes of multiple movable arms 3 via a pivot 15. Multiple fixing plates 14 are fixedly mounted on the bottom of one end of the collecting hopper 1, and each fixing plate 14 is rotatably mounted with a rotating rod 4. Each fixing block 6 has a screw hole inside, and the inner wall of the screw hole of each fixing block 6 is screwed to the outer wall of a screw rod 8. The top end of each screw rod 8 is fixedly connected to the output shaft of a servo motor 7, and the servo motor 7 is fixedly connected to a dam. Each mounting groove 12 is equidistantly opened inside one end of the collecting hopper 1. The top end of each movable arm 3 is movably fitted to the inner wall of the mounting groove 12. Each movable arm 3 is equidistantly fixedly connected to a rotating rod 4. Water permeable holes are opened inside the collecting hopper 1. Water permeable holes are opened inside the side plate 2. The collecting hopper 1 is L-shaped.

[0043] There are two fixing plates 14. There are two fixing blocks 6. There are two side plates 2. There are two servo motors 7. There are two screws 8.

[0044] A servo motor 7 is provided at the top of the screw 8. Preferably, the shovel plate 5 is located on one side of the submersible electro-hydraulic push rod 10.

[0045] Each mounting slot 12 is movably equipped with a movable arm 3.

[0046] The two servo motors operate synchronously.

[0047] The two servo motors 7 rotate synchronously, driving the screws 8 on both sides to rotate. The screws 8 also operate synchronously, transmitting power to the fixed blocks 6. The servo motors 7 at both ends of the collecting hopper 1 cause the outer walls of the screws 8 and the inner walls of the fixed blocks 6 to rotate in a spiral motion simultaneously, causing the fixed blocks 6 and the collecting hopper 1 to move downwards due to gravity. Similarly, when the servo motors 7 at both ends rotate in opposite directions, the collecting hopper 1 moves upwards.

[0048] The selection of this model is for illustrative purposes only, and is not intended to restrict the use of this specific type of synchronous motor. Both servo motors 7, the PLC controller, and the submersible electro-hydraulic actuator 10 are all powered by an external power supply.

[0049] Preferably, the two servo motors 7 are integrated synchronous motors, purchased from Beijing Limaisheng Control Technology Co., Ltd., PSM series PSMP1301K5D-0HSB model and matching power supply circuit;

[0050] The PLC controller and matching power supply circuit were purchased from Fujian Shunchang Hongrun Precision Instruments Co., Ltd., model OHR-PR20-XA.

[0051] Both servo motors 7 have built-in encoders and are connected to the PLC controller; synchronous start-stop and synchronous operation are achieved through electrical signals issued by the PLC controller.

[0052] The submersible electro-hydraulic actuator 10 was purchased from Gaoyou City Tianhua Machinery Factory, model DYTZ300, along with its matching power circuit. Customization is also available to ensure the waterproof performance of the submersible electro-hydraulic actuator 10.

[0053] The control terminal of the submersible electro-hydraulic actuator 10 is electrically connected to the output terminal of the control signal of the PLC controller;

[0054] Two servo motors 7 are fixed at the top of the dam gate, above the drainage hole, i.e. at the top of the dam gate, so that the collection bucket 1 can fit and contact the side wall of the dam gate body 9.

[0055] The specific operation process of the dam gate clearing arm mechanism is as follows:

[0056] Two servo motors 7 are fixedly installed at the top of the dam gate. The top of each screw 8 is vertically fixed to the lower end of the output shaft of each servo motor 7. Each screw 8 is set on the front side of the gate body 9 on the side wall of the dam gate. The fixing blocks 6 at both ends of the collection bucket 1 are installed on the screws 8 on both sides. The collection bucket 1 is adjusted to the upper position of the screw 8. The two servo motors 7 are controlled by the PLC controller to run synchronously in the same direction. The two servo motors 7 drive the two screws 8 to rotate synchronously in the same direction. The screws 8 can screw the fixing blocks 6 and the collection bucket 1 to move down along the gate body 9. During the descent, the collection bucket 1 will also drive the shovel 5 to descend. Due to the close contact between the gate body 9 of the dam gate and the collection bucket 1, the bottom end of the shovel 5 can remove and clean the debris on the surface of the gate body 9 of the dam gate. This device can clean the gate body 9 at any time without waiting for the dry season.

[0057] When the collection bucket 1 is lowered and submerged in water, the PLC controller controls the submersible electro-hydraulic push rod 10 to work. Through the pulling action of the submersible electro-hydraulic push rod 10 and piston rod 11, the movable arm 3 is driven to rotate downward under the action of the rotating rod 4, and the movable arm 3 is adjusted to a horizontal state, that is, the movable arm 3 is parallel to the horizontal plane. The movable arm 3 and the lower end of the collection bucket 1 are submerged in water. The PLC controller controls the two servo motors 7 to rotate synchronously in opposite directions. The two servo motors 7 drive the two screws 8 to rotate synchronously in opposite directions. Through the screw connection between the screws 8 and the fixed block 6, the collection bucket 1 and the movable arm 3 are driven to move upward. Then, the PLC controller controls the submersible electro-hydraulic push rod 10 and piston rod 11 to push the movable arm 3 to rotate in opposite directions, collecting floating objects such as aquatic plants and floating bottles above the water surface of the collection bucket 1 and the movable arm 3, and pushing the floating objects into the collection bucket 1 for collection, while also preventing the floating objects from drifting away. The collection bucket 1 is adjusted upward to move the collection bucket 1 and the floating objects upward. Finally, the debris inside the collection bucket 1 is cleaned manually.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
