Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mountain torrent and debris flow monitoring, and in particular to an intelligent rapid opening and closing device based on an ultra-heavy gate. Background Art
[0002] Natural disasters such as flash floods and debris flows are widely distributed and difficult to monitor in detail. This has led researchers around the world to study the dynamic mechanism of flash floods and debris flows by combining physical model experiments with numerical simulation experiments. The advantage of physical model experiments is that they can intuitively observe the behavior and response of the system and obtain experimental data. However, their disadvantage is that the control of experimental conditions may be limited by factors such as equipment accuracy and experimental scale, and they cannot fully reproduce the complex conditions in the real system. The advantage of numerical simulation is that it can handle more complex and large-scale systems and provide higher spatial and temporal resolution than physical experiments. In scientific research, physical model experiments and numerical simulation experiments often complement each other. Physical experiments provide actual data for verifying and correcting numerical models, while numerical simulations can predict and explain phenomena that are difficult to measure in physical experiments. In order to improve the accuracy and reliability of experimental results, researchers need to accurately control the experimental boundary conditions in the experimental design stage to obtain better experimental repeatability. Among them, the ultra-large-scale "dam break" boundary conditions are close to the prototype scale, and their stringent requirements such as "large scale", "instantaneity" and "watertightness" have become a thorny problem that plagues researchers and engineers at this stage.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.
[0027] See also Figure 1 and Figure 2 The embodiment of the present application provides an intelligent rapid opening and closing device based on an ultra-heavy gate, comprising:
[0028] Material box;
[0029] A gate, the gate is located at one side of the material box, the top of the gate is hinged to the material box, and the bottom of the gate is provided with an automatic locking mechanism;
[0030] The power equipment is connected with the gate through a steel wire rope.
[0031] In some embodiments, an intelligent rapid opening and closing device based on an ultra-heavy-duty gate is applied to a large water tank. When in use, the material box is placed inside the top of the large water tank, and the gate is located on the side close to the downstream of the large water tank.
[0032] It is understandable that the gate is subject to a greater lateral pressure from the clean water or water-soil mixture behind it, so it is necessary to ensure that the gate is water-tight before opening.
[0033] Exemplarily, the power equipment is used for opening and closing the gate, and the power equipment is a high-power high-speed winch-type gate opener with a main motor power of 250KW, a rated gate opening force of 2×125KN, and a rated rope speed of 63 meters per minute.
[0034] Exemplarily, the volume of the water-soil mixture contained in the material box is 500 cubic meters.
[0035] In the present application, soil and water are loaded in the material box, and the "water-tightness" in a "high stress" environment can be met through the gate and the automatic locking mechanism; the automatic locking mechanism can automatically control the rapid opening to meet the "instantaneous opening" requirement of the gate angle exceeding 45° within 5 seconds; the super-heavy gate of the present application can withstand the lateral pressure caused by clean water or water-soil mixture materials, and at the same time, the horizontal extrusion force generated when the automatic locking mechanism is locked makes the gate water seal reach the designed compression amount, thereby satisfying the sealing effect when the water or water-soil mixture generates lateral pressure. In addition, by shortening the time difference between the opening of the automatic locking mechanism and the starting of the power equipment, the motor of the power equipment can be quickly intervened, which in disguise reduces the time that the automatic locking mechanism of the gate is acted upon by hydrostatic pressure or soil pressure after retraction, thereby achieving the purpose of instantaneous release of materials, and can completely realize instantaneous release of materials.
[0036] Working process: When the gate is closed, it is not easy to close tightly due to the existence of lateral pressure. Therefore, two rectangular square holes with a length, width and height of 0.3×0.3×0.5m are reserved at the bottom of the gate, namely the locking grooves. A hydraulic pump support rod is installed above the square hole. The bottom of the support rod is connected to the pin. When the gate is closed (the rotation angle is 0), the rotation angle can be detected by the reading of the pressure sensor on the top to determine the opening and closing angle of the gate. The greater the pressure value of the hydraulic pump, the deeper the depth of the connected pin inserted into the locking groove. The pressure value can be controlled by the electronic control unit to realize the control of the depth of the pin. The pin can be used with the prefabricated locking groove to solve the leakage problem under high stress. When the gate needs to be opened, the electronic control unit first needs to reduce the pressure value of the hydraulic pump to retract the bolt. When it retracts to a position flush with the bottom step of the gate (i.e., just pulled out of the prefabricated square hole), the electronic control unit immediately turns on the motor of the winch hoist, and the wire rope connected to the motor will be tightened, changing the direction of force through the fixed pulley device to lift the gate; when the gate opening and closing angle reaches 45 degrees, the motor stops working and maintains the current torque value to stabilize the gate at a 45-degree opening and closing angle. When the gate needs to be closed, the motor restarts and slowly releases the gate. When the gate opening and closing angle returns to 0 degrees, the motor will re-pressurize the hydraulic pump to reinsert the bolt into the prefabricated square hole to complete the pressurization and fixation to prevent water leakage after the water tank is filled with water.
[0037] See also Figure 1 and Figure 2 In some embodiments, hinge seats are respectively provided on both sides of the top of the gate, and steel wire ropes are respectively provided on both sides of the bottom of the gate, and each of the steel wire ropes is connected to the power equipment.
[0038] It can be understood that the support hinge seat is embedded in both sides of the large concrete water tank through embedded parts.
[0039] It can also be understood that the winch-type gate hoist pulls the wire rope to provide power so that the gate can rotate around the top support hinge seat to open.
[0040] In some embodiments, a bracket is provided above the gate, two fixed pulleys are fixed on the bracket, and each of the steel wire ropes passes around the corresponding fixed pulley and is connected to the power device.
[0041] Furthermore, a pressure sensor is provided at the fulcrum of each fixed pulley.
[0042] Please refer to 1. Figure 2 , Figure 5 and Figure 6 In some embodiments, the automatic locking mechanism includes a locking groove located at the bottom of the gate, a latch matching the locking groove, a hydraulic pump connected to the upper part of the latch, and an oil pump is also provided on one side of the upper part of the material box, and the hydraulic pump is connected to the oil pump.
[0043] Furthermore, the intelligent rapid opening and closing device also includes an electronic control unit, which is electrically connected to the power equipment, the pressure sensor, the hydraulic pump and the oil pump respectively.
[0044] Furthermore, the latch is wedge-shaped, and the locking groove matches the latch.
[0045] It can be understood that the electronic control unit is a conventional control device in the art and will not be described in detail here.
[0046] It can be understood that when the gate is opened or closed, the pressure value at the fulcrum can be monitored by the pressure sensor to determine the opening and closing angle of the gate; when the gate is opening, the pin is first retracted into place and the gate is unlocked, and then the power equipment (winch-type gate opener) quickly intervenes to wind up the wire rope and pull up the gate; when the pressure sensor value exceeds the set maximum value, the motor of the winch-type gate opener stops working to protect the equipment; a high-precision photoelectric encoder is provided at the end of the drum of the winch-type gate opener, which can dynamically control the opening angle of the gate and automatically stop when the gate is opened to the maximum opening and closing angle; in order to further ensure the safety of the rapid opening of the gate, a limit switch is set at the support hinge position. Once the encoder fails, the limit switch will play a role in limit stop protection.
[0047] It can be understood that during the loading process, the gate is closed, and the two hydraulic cylinders inside drive the wedge-shaped pin to insert into the bottom locking groove. The horizontal extrusion force generated by the wedge-shaped locking makes the gate water seal reach the designed compression amount, thereby satisfying the sealing effect when the water or water-soil mixture generates lateral pressure.
[0048] See also Figure 3 and Figure 4 In some embodiments, the gate includes a main frame and a panel welded to the main frame; the main frame includes I-shaped side beams on both sides, a plurality of I-shaped side beams located between the I-shaped side beams, Π The main beam and the bottom beam are arranged at the bottom of the I-shaped side beam. Π I-shaped short beams are laid between the main beams.
[0049] For example, the height of the I-shaped side beam is 1500 mm, the panel is made of 14 mm thick steel plate, and the bottom beam adopts a reinforced box structure to facilitate the arrangement of the automatic locking mechanism.
[0050] It can be understood that the special design of the overall gate meets the strength and rigidity requirements, and the overall deadweight is controlled at about 40 tons. The deadweight is reduced as much as possible while meeting the stress conditions, and it is a heavy-duty flip gate.
[0051] In some embodiments, a water pool is disposed on one side of the material box, and a plurality of rows of through holes are disposed at a portion of the material box adjacent to the water pool.
[0052] In some embodiments, the bottom of the material box is inclined, and the gate is located on the side of the material box with a lower inclination.
[0053] Working process: When the gate is closed, it is not easy to close tightly due to the existence of lateral pressure. Therefore, two rectangular square holes with a length, width and height of 0.3×0.3×0.5m are reserved at the bottom of the gate, namely the locking grooves. A hydraulic pump support rod is installed above the square hole. The bottom of the support rod is connected to the pin. When the gate is closed (the rotation angle is 0), the rotation angle can be detected by the reading of the pressure sensor on the top to determine the opening and closing angle of the gate. The greater the pressure value of the hydraulic pump, the deeper the depth of the connected pin inserted into the locking groove. The pressure value can be controlled by the electronic control unit to realize the control of the depth of the pin. The pin can be used with the prefabricated locking groove to solve the leakage problem under high stress. When the gate needs to be opened, the electronic control unit first needs to reduce the pressure value of the hydraulic pump to retract the bolt. When it retracts to a position flush with the bottom step of the gate (i.e., just pulled out of the prefabricated square hole), the electronic control unit immediately turns on the motor of the winch hoist, and the wire rope connected to the motor will be tightened, changing the direction of force through the fixed pulley device to lift the gate; when the gate opening and closing angle reaches 45 degrees, the motor stops working and maintains the current torque value to stabilize the gate at a 45-degree opening and closing angle. When the gate needs to be closed, the motor restarts and slowly releases the gate. When the gate opening and closing angle returns to 0 degrees, the motor will re-pressurize the hydraulic pump to reinsert the bolt into the prefabricated square hole to complete the pressurization and fixation to prevent water leakage after the water tank is filled with water.

The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
