Description

Technical Field

[0002] Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. Gates are control facilities used to close and open water discharge (release) channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating objects. Gates are mainly composed of three parts: the main active part, the buried part, and the opening and closing equipment. In the construction of canals and dams, the opening and closing gates are key equipment for controlling water flow, and their performance and quality directly affect the safety and benefits of the entire water conservancy project.

[0003] Traditional gate opening and closing usually adopts hydraulic or electric push rods as power sources. These methods have obvious deficiencies in lifting control accuracy and stability. Especially in scenarios where water flow needs to be accurately controlled, its operating accuracy is often difficult to meet the requirements. In addition, during the lifting process, traditional gates are prone to shaking and friction due to the lack of effective guidance and stabilization mechanisms, which not only causes equipment damage, but also may affect the normal operation of the entire water conservancy project. In addition, the design of traditional gates often has problems such as lax closure and aging of sealing materials, resulting in frequent water leakage. Therefore, the utility model proposes a gate opening and closing gate for canal dam construction. Utility Model Content

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] The following is an explanation of the preferred embodiments of the device of the utility model.

[0029] See also Figure 1-4As shown, the gate for opening and closing the canal dam construction includes a base 1, which is U-shaped, and strip slide rails 101 are provided on opposite sides of the base 1. The base 1 serves as a supporting structure for the entire gate opening and closing gate. Its U-shaped design not only provides stable support, but also enables the gate steel plate 4 to move smoothly along the strip slide rails 101 during the lifting process. The setting of the strip slide rails 101 ensures the stability and accuracy of the gate steel plate 4 during the lifting process. A mounting groove 103 is provided in the bottom of the base 1, and a plurality of buffer springs 104 are installed on the mounting groove 103. The buffer springs 104 in the mounting groove 103 play a buffering role when the gate is closed, thereby reducing the impact and vibration between the gate steel plate 4 and the base 1, and extending the service life of the gate. A trapezoidal protrusion 102 is connected to the top of the buffer spring 104, and a gate frame 2 is vertically arranged on the top of the base 1. The gate frame 2 provides a stable support for the lifting mechanism 3.

[0030] The lifting mechanism 3 is symmetrically arranged on the opposite sides of the gate frame 2. The lifting mechanism 3 includes a support plate 301, a servo motor 302, a threaded rod 303, a guide rod 304, a movable slider 305, a connecting rod 306 and a connecting column 307. The servo motor 302 is fixedly installed on the support plate 301. The output end of the servo motor 302 is connected to the threaded rod 303 through a bearing. A guide rod 304 is provided on the side of the threaded rod 303. The ends of the threaded rod 303 and the guide rod 304 away from the support plate 301 are fixedly connected to the top of the base 1, and the movable slider 305 is installed on the outer wall of the threaded rod 303 and the guide rod 304. A connecting rod 306 is provided between the movable sliders 305 on both sides. A plurality of connecting columns 307 are provided on the bottom wall of the connecting rod 306. The bottom of the connecting column 307 is fixedly connected to the gate steel plate 4. Specifically, the servo motor 302 serves as a power source, which drives the threaded rod 303 to rotate, thereby driving the movable slider 305 to move up and down on the threaded rod 303 and the guide rod 304. The connecting rod 306 and the connecting column 307 tightly connect the lifting mechanism 3 and the gate steel plate 4. As the movable slider 305 rises and falls, the connecting rod 306 and the connecting column 307 drive the gate steel plate 4 to perform corresponding lifting movements, thereby realizing the opening and closing of the gate. This design makes the lifting process smooth and controllable, and improves the accuracy and reliability of the gate operation.

[0031] The gate steel plate 4 is fixedly connected to the bottom of the lifting mechanism 3. The bottom of the gate steel plate 4 is provided with a trapezoidal groove 401 that matches the trapezoidal protrusion 102. When the gate steel plate 4 is lowered and closed, there is no reserved gap between the trapezoidal groove 401 at the bottom and the trapezoidal protrusion 102 on the base 1, which not only enhances the sealing of the gate when it is closed and prevents water leakage, but also improves the stability of the gate through the self-locking effect of the trapezoidal structure. In addition, wedge-shaped edges 402 that match the wedge block 7 are cut on both sides of the bottom end of the gate steel plate 4. The cooperation between the wedge block 7 and the wedge-shaped edge 402 at the bottom end of the gate steel plate 4 further enhances the sealing of the gate. When the gate steel plate 4 is lowered and closed, the wedge-shaped edge 402 matches the wedge block 7, effectively preventing water leakage from the bottom of the gate steel plate 4.

[0032] The water retaining plate 5 is covered on the front and rear sides of the gate steel plate 4, and the two sides of the water retaining plate 5 are against the strip slide rail 101. The wedge block 7 is arranged at the bottom of the strip slide rail 101. A limit groove 6 is provided on one side of the wedge block 7. A limit spring 8 is connected to one side of the wedge block 7. A fixed block 9 is connected to the side of the limit spring 8 away from the wedge block 7. A pressure sensor 10 is installed on the top of the fixed block 9. The pressure sensor 10 is connected to the wedge block 7 through the limit spring 8 to monitor the closing state of the gate in real time. When the gate steel plate 4 drops to a certain position, the wedge block 7 is subjected to pressure and is transmitted to the pressure sensor 10 through the limit spring 8. The pressure sensor 10 detects the size of the pressure on the limit spring 8, and the state and sealing of the gate when it is closed can be monitored in real time to ensure the safe and reliable operation of the gate. The servo motor 302 and the pressure sensor 10 are both existing mature technologies and will not be elaborated here.

[0033] When in use, the staff first starts the servo motor 302 in the lifting mechanism 3. Once the servo motor 302 is started, its output end will drive the threaded rod 303 to rotate. Since the moving slider 305 is sleeved on the threaded rod 303, as the threaded rod 303 rotates, the moving slider 305 will move up and down along the track of the threaded rod 303 and the guide rod 304. Through the lifting and lowering movement of the moving slider 305, the connecting rod 306 and the connecting column 307 at its bottom will also rise and fall accordingly, so the gate steel plate 4 will also rise or fall accordingly. The staff can control the positive and negative rotation of the servo motor 302 to adjust the gate steel plate 4. Reversal is used to open or close the gate steel plate 4. When the gate steel plate 4 drops to the closed position, the trapezoidal groove 401 at the bottom of the gate steel plate 4 should be completely matched with the trapezoidal protrusion 102 on the base 1 without any reserved gap. During the closing process, the gate steel plate 4 will compress the wedge block 7 to cause it to move. When the wedge block 7 is under pressure, the pressure is transmitted to the pressure sensor 10 through the limit spring 8. The staff can monitor the feedback signal of the pressure sensor 10 to understand the closing status of the gate in real time. Once the pressure sensor 10 detects sufficient pressure, it can be confirmed that the gate is completely closed.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
