Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering facilities technology, and more specifically, to a novel intelligent gate locking beam for use in extremely humid environments. Background Technology

[0002] As a core component in water conservancy facilities used to stably fix gates in designated positions, the reliability of the gate locking beam plays a crucial role in the safe operation of water conservancy projects. In practical applications, the locking beam is exposed to an extremely humid environment for extended periods. In this environment, a large amount of water vapor, corrosive gases, and salt spray in the air undergo complex electrochemical corrosion reactions with the metal material of the locking beam, leading to the destruction of the protective layer on the surface of the locking beam and causing a series of serious problems. Among these, the springs experience changes in elastic modulus and a decrease in fatigue strength due to corrosion, ultimately resulting in elastic failure; corrosion of the internal raceways and ball surfaces of rolling bearings increases the coefficient of friction, causing jamming; under the influence of corrosion, the effective bearing cross-sectional area of ​​bolts decreases, and stress concentration intensifies, significantly increasing the risk of bolt breakage; simultaneously, the overall structure deteriorates in strength due to corrosion, seriously threatening the stability of the locking beam.

[0003] Moreover, in rivers, lakes and other bodies of water, external forces such as surging waves and water flow impacts are frequent. When the gate is subjected to such external forces, it will shake. Under repeated shaking and impacts, the connection between the locking beam and the gate is prone to loosening, which will lead to displacement of the locking beam. Once the locking beam is displaced, it will not be able to perform its function of fixing the gate properly, which will bring great safety hazards to the water conservancy project and the surrounding area. Utility Model Content

[0004] This utility model aims to provide a novel intelligent gate locking beam for use in extremely humid environments, in order to solve the problems of easy corrosion and failure of existing gate locking beams, easy jamming of structural components, deterioration of structural strength, easy displacement due to surge waves, and significant safety hazards.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model embodiment provides a novel intelligent gate locking beam for use in extremely humid environments, which includes a locking beam body, a hydraulic pump station, and an electrical control cabinet;

[0007] The locking beam body has a first slider and a second slider at both ends. The first slider and the second slider are parallel to each other and spaced apart. The two ends of the locking beam body are fixedly connected to the first slider and the second slider, respectively. The bottom of the first slider and the second slider are slidably connected to a slide rail.

[0008] The locking beam body has a first driving cylinder and a second driving cylinder that are parallel to each other and spaced apart. The telescopic rods of the first driving cylinder and the second driving cylinder are hinged to the locking beam body.

[0009] The aforementioned electrical control cabinet is electrically connected to the aforementioned hydraulic pump station, and the aforementioned hydraulic pump station is connected to the aforementioned first drive cylinder and the aforementioned second drive cylinder.

[0010] When in use, when the locking beam body is engaged, the engagement button of the locking beam body is pressed. The electrical control system determines whether the locking beam body is in the retracted position and whether it is under load. If the locking beam body is in the retracted position and is not under load, the electrical control cabinet receives the signal and electrically controls the hydraulic pump station. The hydraulic pump station injects high-pressure oil into the tail ends of the first drive cylinder and the second drive cylinder. The extension rods of the first drive cylinder and the second drive cylinder push the locking beam body to slide on the first slider and the second slider and engage in place. After the electrical control system receives the engagement signal, the gate is lowered and the locking lug on the gate presses on the locking beam body.

[0011] When the aforementioned locking beam body retracts, pressing the retraction button of the aforementioned locking beam body causes the electrical control system to determine whether the aforementioned locking beam body is in the engaged position and whether it is under load. If the aforementioned locking beam body is in the engaged position and under load, the aforementioned electrical control cabinet receives the signal and electrically controls the aforementioned hydraulic pump station. The aforementioned hydraulic pump station injects high-pressure oil into the first drive cylinder and the first drive cylinder. The extension rods of the first drive cylinder and the second drive cylinder pull the aforementioned locking beam body back into position. After receiving the retraction signal, the electrical control system de-energizes the control equipment.

[0012] The novel intelligent gate locking beam disclosed in this embodiment, designed for use in extremely humid environments, facilitates movement of the locking beam body by employing the aforementioned first and second sliders that slide on corresponding tracks. Furthermore, it utilizes the aforementioned first and second buffer support devices with adaptive buffering and reset functions to prevent structural components from jamming. The addition of the aforementioned first and second drive cylinders facilitates automated driving of the locking beam body. Consequently, this novel intelligent gate locking beam for extremely humid environments offers the advantages of simple structure, resistance to corrosion and failure, reduced structural component jamming, optimized structural strength, minimal displacement, and low safety risks.

[0013] Optionally: The locking beam body has a first L-shaped connector and a second L-shaped connector at both ends, which are respectively connected to the first slider and the second slider. The locking beam body has both ends fixedly connected to the top surfaces of the long sides of the first L-shaped connector and the second L-shaped connector. The bottom surfaces of the long sides of the first L-shaped connector and the second L-shaped connector are fixedly connected to the top surfaces of the first slider and the second slider. The short sides of the first L-shaped connector and the second L-shaped connector are respectively hinged to the telescopic rods of the first drive cylinder and the second drive cylinder.

[0014] With this configuration, the first L-shaped connector and the second L-shaped connector can both support the locking beam body and connect the telescopic rods of the first driving cylinder and the second driving cylinder, making it easier for the telescopic rods of the first driving cylinder and the second driving cylinder to drive the locking beam body to slide on the slide rail, thereby facilitating the stable fixing of the gate in the specified position.

[0015] Optionally, a first buffer support device and a second buffer support device are respectively arranged between the first L-shaped connector and the second L-shaped connector and the two ends of the locking beam body. The bottom ends of the first buffer support device and the second buffer support device abut against the first L-shaped connector and the second L-shaped connector, respectively, and the top ends of the first buffer support device and the second buffer support device are retractably supported on the bottom surfaces of the two ends of the locking beam body.

[0016] With this configuration, the first buffer support device and the second buffer support device have adaptive buffering and reset functions. The first buffer support device and the second buffer support device are installed at both ends of the locking beam body and can withstand the weight and impact transmitted by the locking beam body.

[0017] Optionally: Both the first buffer support device and the second buffer support device have a base, an outer sleeve is fixedly connected to the base, an inner sleeve is provided inside the outer sleeve, a sealing end cap is provided at the end of the inner sleeve away from the base, the sealing end cap is sealably connected to the end of the outer sleeve away from the base, a piston rod is sealably passed through the axis of the sealing end cap, and the end of the piston rod near the base is inserted into the inner sleeve.

[0018] A slidable elastic pressure ring is fitted in the annular gap between the inner sleeve and the outer sleeve. The upper and lower parts of the elastic pressure ring have elastic cavities and non-elastic cavities, respectively. A spring is fitted inside the elastic cavity, and the two ends of the spring elastically abut against the elastic pressure ring and the sealing end cap, respectively.

[0019] The inner sleeve has a rod chamber and a rodless chamber inside. The rod chamber has a piston inside. The outer wall of the piston is in a sealable sliding fit with the inner wall of the inner sleeve. The piston is fixedly connected to the end of the piston rod near the base.

[0020] A plurality of first throttling orifices are provided on the wall of the inner sleeve between the rodless cavity and the non-elastic cavity, and a plurality of second throttling orifices are provided on the wall of the inner sleeve between the rod cavity and the elastic cavity.

[0021] The piston rod is detachably connected to a pressure plate at the end away from the base. The elastic cavity, the non-elastic cavity, the rod cavity, and the rodless cavity are all filled with hydraulic oil.

[0022] With this configuration, when the locking beam body is subjected to gate pressure, the pressure is transmitted to the piston through the piston rod. The piston compresses the hydraulic oil in the rodless chamber, which then flows through the first throttling orifice to the non-elastic chamber, continuing to apply pressure to the elastic pressure ring and the spring. The spring undergoes compression deformation under pressure, thus reducing the space within the elastic chamber. Under pressure, the hydraulic oil in the elastic chamber flows through the second throttling orifice to the rod chamber. At this time, the piston moves downward, thereby buffering the locking beam pressure and adapting to… The elastic component undergoes compression deformation; when the pressure on the locking beam body is released, the spring returns to its initial state by its own elastic force. During this process, the hydraulic oil in the non-elastic chamber is subjected to the reverse action of the spring force and flows back to the rodless chamber through the first throttle orifice. The hydraulic oil in the rodless chamber then pushes the piston upward, while the hydraulic oil in the rod chamber flows out to the elastic chamber through the second throttle orifice due to the compression of the piston, in order to make up for the volume difference caused by the spring's recovery. Finally, the locking beam body returns to its initial position.

[0023] Optionally, a weighing device is clamped between the first buffer support device and the second buffer support device and the first L-shaped connector and the second L-shaped connector, and the weighing device is electrically connected to the electrical control cabinet.

[0024] With this configuration, the weighing device is used to detect whether the locking beam body is carrying the gate, and to determine the unlocking conditions in the electrical control logic, so as to prevent maloperation when the locking beam body is carrying the gate, thereby avoiding the locking beam body from accidentally exiting the locked state.

[0025] Optionally: Both the first slider and the second slider are rectangular grooves, and the slide is horseshoe-shaped, with the first slider and the second slider slidably clamped on the slide.

[0026] This design, by employing a sliding displacement mechanism, effectively reduces resistance during sliding friction and prevents parts from rusting and jamming in humid environments.

[0027] Optionally, a first moving auxiliary rod and a second moving auxiliary rod are fixedly connected to both ends of the locking beam body.

[0028] This configuration ensures that in the event of a failure of the automated system, the connection between the first and second drive cylinders and the locking beam body can be manually disconnected, and the locking beam body can be easily moved by manually pushing the first and second moving auxiliary rods.

[0029] Optionally: the front end and rear end of the first driving cylinder are respectively provided with a first oil port and a second oil port, and the front end and rear end of the second driving cylinder are respectively provided with a third oil port and a fourth oil port;

[0030] A first hydraulic line is connected between the first oil port and the hydraulic pump station, and a second hydraulic line is connected between the third oil port and the hydraulic pump station.

[0031] A third hydraulic line is connected between the second oil port and the fourth oil port. The third hydraulic line has a tee, and a fourth hydraulic line is connected between the tee and the hydraulic pump station.

[0032] With this configuration, when the locking beam body needs to stably fix the gate in a specified position, the hydraulic pump station injects high-pressure oil into the second and fourth oil ports through the fourth and third hydraulic lines. At this time, the telescopic rods of the first and second drive cylinders push the locking beam body to slide to a suitable position, and the gate is mounted on the locking beam body. When the locking beam body does not need to stably fix the gate in a specified position, the hydraulic pump station injects high-pressure oil into the first and third oil ports through the first and second hydraulic lines. At this time, the telescopic rods of the first and second drive cylinders retract, allowing the locking beam body to slide to its initial position, facilitating the lowering of the gate to achieve closure.

[0033] Optionally: The first driving cylinder and the second driving cylinder are both radially hinged to a hinge seat, the bottom of the hinge seat is provided with a base, and the bottom surface of the hinge seat is rotatably connected to the top surface of the base.

[0034] This configuration ensures that in the event of a failure of the automated system, the connection between the first and second drive cylinders and the locking beam body, as well as the connection between the first and second drive cylinders and the first, second, third, and fourth hydraulic lines, can be manually disengaged. The first and second drive cylinders can then be rotated 90° in place, facilitating manual movement of the locking beam body.

[0035] Optionally, a monitoring camera is provided on the side of the locking beam body away from the first drive cylinder and the second drive cylinder.

[0036] With this setup, the monitoring camera is installed on the outside of the aforementioned locking beam body to monitor the displacement of the locking beam body and transmit the monitoring image to the hoist, making it convenient for the driver to remotely operate and observe.

[0037] Optionally, the outer wall of the aforementioned locking beam body is treated with zinc spraying for corrosion protection.

[0038] This design effectively prevents the locking beam body from rusting in extremely humid environments, thus improving its corrosion resistance.

[0039] Optionally, the electrical control cabinet described above is equipped with a wireless control transmission system.

[0040] This setup allows operators to control the system remotely from inside the driver's cab.

[0041] Optionally, the aforementioned hydraulic pump station, electrical control cabinet, and monitoring camera all meet the IP68 protection rating.

[0042] With this configuration, the IP68 protection rating provides high dust and water resistance, making the aforementioned hydraulic pump station, electrical control cabinet, and surveillance camera less susceptible to damage.

[0056] Example

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 This embodiment proposes a novel intelligent gate locking beam for use in extremely humid environments, including a locking beam body 1, a hydraulic pump station 2, and an electrical control cabinet 3;

[0058] The locking beam body 1 has a first slider 4 and a second slider 5 at both ends. The first slider 4 and the second slider 5 are parallel to each other and spaced apart. The two ends of the locking beam body 1 are fixedly connected to the first slider 4 and the second slider 5 respectively. The bottom of the first slider 4 and the second slider 5 are slidably connected to the slide rail 6.

[0059] A first driving cylinder 7 and a second driving cylinder 8 are provided on one side of the locking beam body 1, which are parallel to each other and spaced apart. The telescopic rods of the first driving cylinder 7 and the second driving cylinder 8 are hinged to the locking beam body 1.

[0060] The electrical control cabinet 3 is electrically connected to the hydraulic pump station 2, and the hydraulic pump station 2 is connected to the first drive cylinder 7 and the second drive cylinder 8.

[0061] When in use, when locking beam body 1 is engaged, press the engagement button of locking beam body 1. The electrical control system determines whether locking beam body 1 is in the retracted position and whether it is under load. If locking beam body 1 is in the retracted position and is not under load, electrical control cabinet 3 receives the signal and electrically controls hydraulic pump station 2. Hydraulic pump station 2 injects high-pressure oil into the tail end of first drive cylinder 7 and second drive cylinder 8. The extension rods of first drive cylinder 7 and second drive cylinder 8 push locking beam body 1 to slide on first slider 4 and second slider 5 and engage in position. After the electrical control system receives the engagement signal, the gate is lowered and the locking lug on the gate presses on locking beam body 1.

[0062] When locking beam body 1 is released, press the release button of locking beam body 1. The electrical control system determines whether locking beam body 1 is in the engaged position and whether it is under load. If locking beam body 1 is in the engaged position and under load, electrical control cabinet 3 receives the signal and electrically controls hydraulic pump station 2. Hydraulic pump station 2 injects high-pressure oil into the head end of first drive cylinder 7 and second drive cylinder 8. The extension rods of first drive cylinder 7 and second drive cylinder 8 pull locking beam body 1 back into position. After receiving the return signal, the electrical control system de-energizes the control equipment.

[0063] The novel intelligent gate locking beam disclosed in this embodiment, designed for use in extremely humid environments, facilitates the movement of the locking beam body 1 by employing a first slider 4 and a second slider 5 that slide on corresponding slide rails 6. Furthermore, it utilizes a first buffer support device 11 and a second buffer support device 12 with adaptive buffering and reset functions to prevent structural components from jamming. The addition of a first drive cylinder 7 and a second drive cylinder 8 facilitates automated driving of the locking beam body 1. Consequently, this novel intelligent gate locking beam for extremely humid environments offers the advantages of simple structure, resistance to corrosion and failure, reduced structural component jamming, optimized structural strength, minimal displacement, and low safety risks.

[0064] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The locking beam body 1 is provided with a first L-shaped connector 9 and a second L-shaped connector 10 at both ends between the first slider 4 and the second slider 5. The two ends of the locking beam body 1 are fixedly connected to the top surfaces of the long sides of the first L-shaped connector 9 and the second L-shaped connector 10, respectively. The bottom surfaces of the long sides of the first L-shaped connector 9 and the second L-shaped connector 10 are fixedly connected to the top surfaces of the first slider 4 and the second slider 5, respectively. The short sides of the first L-shaped connector 9 and the second L-shaped connector 10 are hinged to the telescopic rods of the first driving cylinder 7 and the second driving cylinder 8, respectively. The first L-shaped connector 9 and the second L-shaped connector 10 can both support the locking beam body 1 and connect the telescopic rods of the first driving cylinder 7 and the second driving cylinder 8, so that the telescopic rods of the first driving cylinder 7 and the second driving cylinder 8 can drive the locking beam body 1 to slide on the slide rail 6, thereby facilitating the stable fixing of the gate in the specified position.

[0065] A first buffer support device 11 and a second buffer support device 12 are respectively arranged between the first L-shaped connector 9 and the second L-shaped connector 10 and the two ends of the locking beam body 1. The bottom ends of the first buffer support device 11 and the second buffer support device 12 abut against the first L-shaped connector 9 and the second L-shaped connector 10 respectively. The top ends of the first buffer support device 11 and the second buffer support device 12 are retractably supported on the bottom surfaces of the two ends of the locking beam body 1. The first buffer support device 11 and the second buffer support device 12 have adaptive buffering and reset functions. The first buffer support device 11 and the second buffer support device 12 are installed at both ends of the locking beam body 1 and can withstand the weight and impact transmitted by the locking beam body 1.

[0066] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8Both the first buffer support device 11 and the second buffer support device 12 have a base 13. An outer sleeve 14 is fixedly connected to the base 13. A coaxial inner sleeve 15 is provided inside the outer sleeve 14. A sealing end cap 16 is provided at the end of the inner sleeve 15 away from the base 13. The sealing end cap 16 is sealably connected to the end of the outer sleeve 14 away from the base 13. A piston rod 17 is sealably passed through the axis of the sealing end cap 16. The end of the piston rod 17 near the base 13 is inserted into the interior of the inner sleeve 15. A slidable elastic pressure ring 18 is fitted in the annular gap between the inner sleeve 15 and the outer sleeve 14. The upper and lower parts of the elastic pressure ring 18 have elastic cavities 19 and non-elastic cavities 19, respectively. The elastic cavity 20 and elastic cavity 19 are fitted with springs 21, the two ends of which elastically abut against the elastic pressure ring 18 and the sealing end cap 16, respectively. The inner sleeve 15 has a rod cavity 22 and a rodless cavity 23. The rod cavity 22 has a piston 24, the outer wall of which is in a sealing sliding fit with the inner wall of the inner sleeve 15. The piston 24 is fixedly connected to the end of the piston rod 17 near the base 13. Several first throttling holes 25 are opened on the wall of the inner sleeve 15 between the rodless cavity 23 and the non-elastic cavity 20. Several second throttling holes 26 are opened on the wall of the inner sleeve 15 between the rod cavity 22 and the elastic cavity 19. The piston rod 17 is away from the base 13. A pressure plate 27 is detachably connected at one end. The interiors of the elastic chamber 19, non-elastic chamber 20, rod chamber 22, and rodless chamber 23 are all filled with hydraulic oil (not shown in the figure). When the locking beam body 1 is subjected to gate pressure, this pressure is transmitted to the piston 24 through the piston rod 17. The piston 24 compresses the hydraulic oil in the rodless chamber 23. The hydraulic oil in the rodless chamber 23 then flows to the non-elastic chamber 20 through the first throttle orifice 25 and continues to apply pressure to the elastic pressure ring 18 and the spring 21. After being compressed, the spring 21 undergoes compression deformation, and the space in the elastic chamber 19 is reduced as a result. Under pressure, the hydraulic oil in the elastic chamber 19 flows to the rod chamber 22 through the second throttle orifice 26. At this time, the piston 24 moves downward, thereby buffering the pressure of the locking beam and adapting to the compression deformation of the elastic component. When the pressure of the locking beam body 1 is released, the spring 21 returns to its initial state by its own elastic force. During this process, the hydraulic oil in the non-elastic chamber 20 is subjected to the reverse action of the spring force of the spring 21 and flows back to the rodless chamber 23 through the first throttle hole 25. The hydraulic oil in the rodless chamber 23 then pushes the piston 24 to move upward, while the hydraulic oil in the rod chamber 22 flows out to the elastic chamber 19 through the second throttle hole 26 due to the compression of the piston 24, in order to make up for the volume difference caused by the recovery of the spring 21. Finally, the locking beam body 1 returns to its initial position.

[0067] Weighing devices 28 are clamped between the first buffer support device 11 and the second buffer support device 12 and the first L-shaped connector 9 and the second L-shaped connector 10. The weighing devices 28 are electrically connected to the electrical control cabinet 3. The weighing devices 28 are used to detect whether the locking beam body 1 is carrying the gate and to judge the unlocking conditions in the electrical control logic to prevent maloperation when the locking beam body 1 is carrying the gate, thereby avoiding the locking beam body 1 from accidentally exiting the locking state.

[0068] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The first slider 4 and the second slider 5 are both rectangular grooves, and the slide 6 is horseshoe-shaped. The first slider 4 and the second slider 5 are slidably clamped on the slide 6. By adopting the sliding displacement form, the resistance during sliding friction is effectively reduced, and the component is prevented from rusting and jamming in a humid environment.

[0069] The locking beam body 1 is fixedly connected to the first moving auxiliary rod 29 and the second moving auxiliary rod 30 at both ends, which ensures that when the automation system fails, the connection between the first driving cylinder 7 and the second driving cylinder 8 and the locking beam body 1 can be manually disconnected. The locking beam body 1 can be easily moved by manually pushing the first moving auxiliary rod 29 and the second moving auxiliary rod 30.

[0070] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The first drive cylinder 7 has a first oil port 31 and a second oil port 32 at its front and rear ends, respectively, and the second drive cylinder 8 has a third oil port 33 and a fourth oil port 34 at its front and rear ends, respectively. A first hydraulic pipeline 35 connects the first oil port 31 to the hydraulic pump station 2, and a second hydraulic pipeline 36 connects the third oil port 33 to the hydraulic pump station 2. A third hydraulic pipeline 37 connects the second oil port 32 and the fourth oil port 34. A tee 38 is provided on the third hydraulic pipeline 37, and a fourth hydraulic pipeline 39 connects the tee 38 to the hydraulic pump station 2. When the locking beam body 1 needs to stably fix the gate in a specified position, the hydraulic pump station 2... High-pressure oil is injected into the second oil port 32 and the fourth oil port 34 through the fourth hydraulic line 39 and the third hydraulic line 37. At this time, the telescopic rods of the first drive cylinder 7 and the second drive cylinder 8 push the locking beam body 1 to slide to the appropriate position, and the gate is mounted on the locking beam body 1. When the locking beam body 1 does not need to stabilize the gate in the specified position, the hydraulic pump station 2 injects high-pressure oil into the first oil port 31 and the third oil port 33 through the first hydraulic line 35 and the second hydraulic line 36. At this time, the telescopic rods of the first drive cylinder 7 and the second drive cylinder 8 retract, so that the locking beam body 1 slides to the initial position, which facilitates the gate to be lowered to achieve the closing of the gate.

[0071] The first drive cylinder 7 and the second drive cylinder 8 are both radially hinged to hinge seats 40. The bottom of the hinge seat 40 is provided with a base 41. The bottom surface of the hinge seat 40 is rotatably connected to the top surface of the base 41. This ensures that in the event of a failure of the automation system, the connection between the first drive cylinder 7 and the second drive cylinder 8 and the locking beam body 1, as well as the connection between the first drive cylinder 7 and the second drive cylinder 8 and the first hydraulic line 35, the second hydraulic line 36, the third hydraulic line 37, and the fourth hydraulic line 39 can be manually disengaged. The first drive cylinder 7 and the second drive cylinder 8 can then be rotated 90° in place, making it convenient for manual pushing of the locking beam body 1.

[0072] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A monitoring camera (not shown in the figure) is provided on the side of the locking beam body 1 away from the first drive cylinder 7 and the second drive cylinder 8. The monitoring camera is installed on the outside of the locking beam body 1 to monitor the displacement of the locking beam body 1 and transmit the monitoring image to the hoist for remote operation and observation by the driver.

[0073] The outer wall of the locking beam body 1 is treated with zinc spraying for corrosion protection, which effectively prevents rusting in extremely humid environments and improves the corrosion resistance of the locking beam body 1.

[0074] The electrical control cabinet 3 is equipped with a wireless control transmission system (not shown in the figure), which allows operators to remotely control the equipment from the driver's cab.

[0075] Hydraulic pump station 2, electrical control cabinet 3 and monitoring camera all reach IP68 protection level. IP68 protection level has high dustproof and waterproof, making hydraulic pump station 2, electrical control cabinet 3 and monitoring camera not easy to be damaged.

[0076] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The specific control method for the locking beam of the novel intelligent gate in extremely humid environments in this embodiment is as follows:

[0077] When locking beam body 1 is engaged, the engagement button of locking beam body 1 is pressed. The electrical control system determines whether locking beam body 1 is in the retracted position and whether it is under load. If locking beam body 1 is in the retracted position and is not under load, electrical control cabinet 3 receives the signal and electrically controls hydraulic pump station 2. Hydraulic pump station 2 injects high-pressure oil into the tail ends of first drive cylinder 7 and second drive cylinder 8 through third hydraulic pipeline 37 and fourth hydraulic pipeline 39 respectively. The extension rods of first drive cylinder 7 and second drive cylinder 8 push locking beam body 1 into position. After receiving the engagement signal, the gate is lowered and the locking lug on the gate presses on locking beam body 1. Weighing device 28 detects the pressure and transmits it to the electrical control system. The electrical control system then de-energizes the equipment.

[0078] When locking beam body 1 is released, press the release button of locking beam body 1. The electrical control system determines whether locking beam body 1 is in the engaged position and whether it is under load. If locking beam body 1 is in the engaged position and under load, electrical control cabinet 3 receives the signal and electrically controls hydraulic pump station 2. Hydraulic pump station 2 injects high-pressure oil into the head end of first drive cylinder 7 and second drive cylinder 8 through first hydraulic pipeline 35 and second hydraulic pipeline 36 respectively. The extension rods of first drive cylinder 7 and second drive cylinder 8 pull locking beam body 1 back into position. After receiving the return signal, the electrical control system de-energizes the control equipment.

[0079] Before the locking beam body 1 is moved, the gate must be lifted to prevent the gate from being mounted on the locking beam body 1, otherwise the locking beam cannot be controlled.

[0080] In this embodiment, a filling hole 56 is provided radially on the outer wall of the outer sleeve 14. The filling hole 56 facilitates the worker to inject hydraulic oil into the first buffer support device 11 and the second buffer support device 12, or facilitates the discharge of hydraulic oil inside the first buffer support device 11 and the second buffer support device 12, so as to facilitate replacement or maintenance.

[0081] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the locking beam body 1 is made of Q355 material, all connecting parts are made of stainless steel bolts, and the locking beam body 1 is treated with zinc spraying anti-corrosion process, which can effectively prevent rust in extremely humid environments and improve the corrosion resistance of the locking beam body 1.

[0082] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, to prevent the rolling bearing from rusting and jamming in a humid environment, the locking beam body 1 and the slide rail 6 adopt a sliding displacement form. A first slider 4 and a second slider 5 made of high-strength wear-resistant composite material are installed at the bottom of the locking beam body 1. The friction surfaces of the first slider 4 and the second slider 5 have a self-lubricating function, which can effectively reduce the resistance during sliding friction. The slide rail 6 adopts a horseshoe shape with a smooth transition at the edge. A certain distance gap is reserved between the first slider 4 and the second slider 5 and the two sides of the slide rail 6 to prevent the locking beam body 1 from shifting and jamming.

[0083] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8In this embodiment, to prevent the gate from swaying under the action of external forces such as surging waves, causing displacement of the locking beam body 1, and considering that the sliding form of the locking beam body 1 leads to increased friction, a hydraulic pump station 2, a first drive cylinder 7, and a second drive cylinder 8 are provided for the deployment and retraction of the locking beam body 1. The first drive cylinder 7 and the second drive cylinder 8 are installed at appropriate positions on both sides of the selected beam. The extension rods of the first drive cylinder 7 and the second drive cylinder 8 are connected to the locking beam body 1, and the other end is connected to a rotatable hinge seat 40 fixed on a concrete base 41. The hydraulic pump station 2 includes components such as a motor, oil pump, and valves, which are integrated and installed in a tank with an IP68 waterproof rating. This tank is made of stainless steel. Hydraulic lines 35, 36, 37, and 39 extend from the tank body and connect to the first drive cylinder 7 and the second drive cylinder 8. On the concrete foundation, seamless steel pipes are used to arrange the hydraulic lines 35, 36, 37, and 39. At a position approximately 1.5 meters from the cylinder, the hydraulic lines 35, 36, 37, and 39 are converted into high-pressure hoses and connected to either the first drive cylinder 7 or the second drive cylinder 8. In addition, the hydraulic pump station 2 is equipped with an emergency external pressure interface, which can be connected to an emergency pump station as a temporary power source in case of pump failure.

[0084] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, a hydraulic system control box is installed at a suitable location near the locking beam. The electrical control cabinet 3 has IP68 waterproof function and is made of stainless steel. The cables, power supply cables, and camera image transmission cables between the hydraulic pump station 2 and the control box are all axially sealed cables to prevent moisture from entering the cabinet. The electrical control cabinet 3 has a built-in wireless control transmission system, which allows the operator to remotely control the system from the driver's cab. At the same time, the waterproof camera deployed on site will transmit the real-time monitoring image to the image monitoring screen in the driver's cab. The driver can monitor the entire locking beam deployment and retraction process and can stop the operation immediately if any abnormality is found.

[0085] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8In this embodiment, the hydraulic system of the locking beam drive device includes a left cylinder position sensor 42, a right cylinder position sensor 43, a hydraulic control check valve 50 44, a synchronization valve 45, a throttle valve 46, a YV1 reversing valve 47, a YV2 reversing valve 48, a YV3 reversing valve 49, a check valve 50, a system relief valve 51, a pressure sensor 52, a pressure gauge 53, an oil pump motor unit 54, an oil tank 55, and accessories.

[0086] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 Logic flow of the electronic control system:

[0087] 1. When the locking beam engagement button is pressed, if no exit signal is received, the program ends and an alarm sounds. If an exit signal is received, the system weighing device 28 determines whether to weigh. If weighing is received, the program ends and an alarm sounds. If no weighing is received, the locking beam oil pump motor is turned on. After a five-second delay, the system weighing device 28 determines whether to weigh again. If weighing is received, the program ends and an alarm sounds. If no weighing is received, the solenoid YV1 reversing valve 47 and YV2 reversing valve 48 are energized. If the system does not receive a locking beam engagement signal within sixty seconds, the locking beam oil pump motor is turned off, the solenoid YV1 reversing valve 47 and YV2 reversing valve 48 are de-energized, and an alarm sounds. If the system receives a locking beam engagement signal within sixty seconds, the locking beam oil pump motor is turned off, the solenoid YV1 reversing valve 47 and YV2 reversing valve 48 are de-energized, and the program ends after three seconds.
