Description

Technical Field

[0001] This application relates to the field of gates, and in particular to a safety device for an integrated gate. Background Technology

[0002] Integrated gates are widely used as important control devices in water conservancy projects, urban drainage systems, and industrial facilities for regulating and blocking water flow. Existing integrated gates typically consist of a lifting mechanism and a gate panel. The lifting mechanism is fixedly connected to the gate panel via mechanical connecting components to achieve the lifting and lowering operation of the panel. While this design has demonstrated a certain level of reliability in long-term use, it also presents significant safety hazards. Specifically, after the gate panel is raised, its weight relies entirely on the connecting components between the lifting mechanism and the panel. However, these connecting components are susceptible to environmental factors (such as corrosion and wear) and mechanical stress (such as frequent lifting and lowering operations) during long-term use, leading to aging, deformation, and even breakage. If the connecting components fail, the gate panel may suddenly fall uncontrollably, not only affecting the normal operation of the gate but also potentially posing a serious safety threat to operators or surrounding facilities.

[0003] The shortcomings of existing technologies mainly stem from their simplistic design and over-reliance on the reliability of connecting components. Although some gate devices are equipped with additional safety devices, these devices are often complex in structure, expensive, and difficult to completely prevent accidents in practical applications. Furthermore, the maintenance and repair of existing safety devices are cumbersome, increasing operating costs and management difficulty. The root cause of these problems is that existing technologies fail to fundamentally solve the vulnerability of connecting components, instead relying on additional devices to compensate for design flaws, resulting in an inability to achieve an optimal balance between the safety and economy of the overall system.

[0004] To address the aforementioned issues, developing a new type of integrated safety device for gates is of significant practical importance. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the prior art and provide an integrated safety device for gates that can prevent the gate panel from falling suddenly in the event of failure of connecting parts, thereby ensuring the safety of equipment and personnel.

[0006] To achieve the above objectives, this application discloses an integrated safety device for a gate, which includes limiters symmetrically installed in the gate panel and support plates symmetrically and vertically installed in the guide grooves on both sides of the gate fixing frame.

[0007] The limiter consists of a hydraulic drive mechanism, a limit pin, a mounting housing, and a guide mechanism. The limit pin is fixed inside the gate plate through the mounting housing. The mounting housing has a guide groove inside. One end of the limit pin is fixedly connected to the piston rod of the hydraulic cylinder by a thread or pin, and the other end can extend and retract horizontally along the guide groove under hydraulic drive.

[0008] The guide groove is equipped with a sliding bearing or a lubricating coating to reduce the frictional resistance when the limit pin moves, and to ensure the smoothness and accuracy of its extension and retraction.

[0009] The hydraulic drive mechanism includes a hydraulic cylinder, hydraulic lines and a control unit. The hydraulic cylinder is connected to an external manual or electric control device through the hydraulic lines. The control unit is used to adjust the working state of the hydraulic cylinder, thereby controlling the horizontal extension and retraction of the limit pin.

[0010] The support plate is symmetrically and vertically installed in the guide grooves on both sides of the gate fixing frame. The top of the plate has a semi-circular groove that cooperates with the limiting pin. The design of the semi-circular groove allows the limiting pin to form a larger contact area with the inner wall of the groove when it enters the groove, thereby improving the stability and load-bearing capacity of the support.

[0011] The groove is fitted with a semi-circular shock-absorbing rubber block that matches the shape of the groove. The shock-absorbing rubber block is connected to the inner wall of the groove by adhesive or mechanical fixation. It is used to provide a buffering effect when the limit pin enters the groove, reducing the impact of the impact on the device. The design of the semi-circular shock-absorbing rubber block not only enhances the buffering effect, but also improves the durability and wear resistance of the device.

[0012] The support plate is fixedly connected to the gate fixing frame by bolts or welding to ensure its structural stability and load-bearing capacity.

[0013] Specifically, during operation, when the gate panel unexpectedly falls due to connection component failure or other reasons, the hydraulic drive assembly, under the control of the control unit, quickly activates, driving the limit pin to extend horizontally along the guide groove to the side of the gate panel. The extended limit pin enters the semi-circular groove at the top of the support plate and contacts the semi-circular shock-absorbing rubber block. Through the cooperation between the limit pin and the groove, the falling movement of the gate panel is effectively stopped. The installation of the shock-absorbing rubber block not only reduces the impact force when the limit pin contacts the groove, but also reduces wear on the device during long-term use, extending its service life.

[0014] As an optional technical solution, to further enhance the safety and reliability of the device, this application also includes an alarm device installed inside the gate panel. This alarm device includes a waterproof box, an accelerometer sensor installed inside the waterproof box, a battery, and a control board. The control board integrates a communication module for wireless communication. The accelerometer sensor monitors the movement state of the gate panel; when an abnormal drop is detected, the control board triggers an alarm signal. Furthermore, indicator lights or mechanical indicators can be installed on the gate panel to visually display the extension status of the limit pins. Specifically, the indicator lights can be LEDs, and the mechanical indicators can be connected to the limit pins via mechanical linkage to ensure the accuracy and reliability of the indication.

[0015] Furthermore, the alarm device integrates a position sensor or displacement sensor to monitor the extension status of the limit pin in real time. Specifically, the position sensor is installed inside the mounting housing of the limit pin or near the piston rod of the hydraulic cylinder to detect the horizontal displacement of the limit pin. When the limit pin extends under hydraulic drive, the position sensor detects the displacement change and transmits the signal to the control board. The control board determines whether the limit pin is fully extended based on the received signal and triggers an alarm signal if the limit pin is not fully extended or not extended at all.

[0016] As an optional technical solution, the position sensor can be a magnetic proximity switch or a photoelectric sensor. A magnetic proximity switch determines its position by detecting the magnetic element on a limit pin, while a photoelectric sensor determines its extension state by detecting whether the limit pin blocks the light path. Both types of sensors have high accuracy and reliability, and can meet the usage requirements of the device.

[0017] Specifically, the control board integrates a signal processing module and a communication module for processing and transmitting sensor signals. When the position sensor detects that the limit pin is not fully extended or not extended at all, the control board will send an alarm signal to the remote monitoring terminal through the communication module.

[0018] Furthermore, the alarm device is connected to the control unit of the hydraulic drive assembly for automated control. When the position sensor detects that the limit pin is not fully extended, the control board immediately activates the hydraulic drive assembly, driving the limit pin to extend further until it reaches the preset position. Simultaneously, the control board triggers an alarm signal to alert the operator. This automated design not only improves the device's response speed but also enhances its operational efficiency and safety.

[0019] The technical solution of this application achieves effective protection against accidental gate panel falls by precisely matching the hydraulically driven limit pin with the semi-circular groove of the support plate. The limiter and support plate have a reasonable structural design and a stable connection, which can significantly improve the safety performance of the integrated gate. At the same time, the device has a simple structure, reliable operation, and low maintenance cost, and has high practical value and application prospects.

[0028] See attached document Figure 1 and 2 This embodiment relates to an exemplary structure of an integrated gate safety device. Its structure mainly includes limiters 3 symmetrically installed within the gate panel 1, support plates 5 symmetrically and vertically installed in guide grooves on both sides of the gate fixing frame 2, and an alarm device 6 for monitoring and alarm functions. The limiters 3 consist of a hydraulic drive assembly, limit pins 4, a mounting housing, and a guide mechanism. The hydraulic drive assembly includes a hydraulic cylinder, hydraulic lines, and a control unit. The hydraulic cylinder is connected to an external manual or electric control device via hydraulic lines. The control unit is used to adjust the working state of the hydraulic cylinder, thereby precisely controlling the horizontal extension and retraction of the limit pins 4. The limit pins 4 are fixed inside the gate panel 1 by the mounting housing. The mounting housing has a guide groove. One end of the limit pin 4 is fixedly connected to the piston rod of the hydraulic cylinder by threads or a pin, and the other end can extend and retract horizontally along the guide groove under hydraulic drive. The guide groove is provided with sliding bearings or a lubricating coating to reduce the frictional resistance of the limit pins 4 during movement, ensuring the smoothness and accuracy of their extension and retraction.

[0029] The support plates 5 are symmetrically and vertically installed in the guide grooves on both sides of the gate fixing frame 2, and their top ends have semi-circular grooves that mate with the limit pins 4. The semi-circular groove design allows the limit pins 4 to form a larger contact area with the inner wall of the groove when entering it, thereby improving the stability and load-bearing capacity of the support. Semi-circular shock-absorbing rubber blocks, matching the shape of the groove, are embedded within the groove. These blocks are connected to the inner wall of the groove by adhesive or mechanical fixing, providing a buffering effect when the limit pins 4 enter the groove, reducing the impact of the force on the device. The support plates 5 are fixedly connected to the gate fixing frame 2 by bolts or welding to ensure structural stability and load-bearing capacity.

[0030] It is important to note that the installation position and dimensions of the support plate 5 must be designed to ensure that it is located within the guide groove and that it does not affect the sliding fit between the gate fixing frame 2 and the gate plate 1. Specifically, the width and thickness of the support plate 5 should match the dimensions of the guide groove to avoid interference or friction during the raising and lowering of the gate plate 1. Furthermore, the installation height of the support plate 5 should be lower than the lowest position of the gate plate 1 to ensure that the gate plate 1 does not contact the support plate 5 when fully closed.

[0031] In practical implementation, the control unit of the hydraulic drive assembly can be operated via an external manual or electric control device. For example, the operator can send commands through a control panel or remote terminal to control the movement of the piston rod of the hydraulic cylinder, thereby driving the limit pin 4 to extend and retract horizontally. The piston rod of the hydraulic cylinder and the limit pin 4 are connected by threads or pins to ensure the reliability and stability of the transmission. The hydraulic pipeline uses high-pressure resistant hoses or rigid pipes, and the specific material can be selected according to the actual use environment. For example, stainless steel can be used in corrosive environments. The working principle of the hydraulic drive assembly is well known to those skilled in the art and will not be described in detail here.

[0032] The guide groove of the limit pin 4 is equipped with a sliding bearing or a lubricating coating to reduce the frictional resistance when the limit pin 4 moves, and to ensure the smoothness and accuracy of its extension and retraction.

[0033] Sliding bearings can use self-lubricating materials, such as polytetrafluoroethylene (PTFE), to reduce maintenance costs. Lubricating coatings can be made of molybdenum disulfide (MoS2) or graphite to improve wear resistance and lubrication.

[0034] The material of the limit pin 4 can be selected according to actual usage requirements. For example, high-strength alloy steel can be used in heavy-duty environments to improve its load-bearing capacity and service life.

[0035] The semi-circular groove design of the support plate 5 matches the shape of the limiting pin 4, ensuring that the limiting pin 4 can form a larger contact area with the inner wall of the groove when it enters the groove, thereby improving the stability and load-bearing capacity of the support.

[0036] The semi-circular shock-absorbing rubber blocks can be made of natural or synthetic rubber, such as nitrile rubber (NBR) or neoprene rubber (CR), to improve their cushioning effect and durability. The shock-absorbing rubber blocks are connected to the inner wall of the groove by adhesive or mechanical fixing. The specific fixing method can be selected according to the actual use requirements. For example, high-temperature resistant adhesives can be used in high-temperature environments.

[0037] The alarm device 6 includes a waterproof box, an accelerometer sensor installed inside the waterproof box, a battery, and a control board. The control board integrates a communication module for wireless communication, enabling real-time transmission of the limit pin 4's status information to a remote monitoring terminal. The accelerometer sensor monitors the movement of the gate panel 1; when an abnormal drop is detected, the control board triggers an alarm signal. The waterproof box can be made of engineering plastics or aluminum alloy to improve its waterproof performance and durability. The battery can be a lithium battery or a nickel-metal hydride battery to ensure long-term stable operation of the device. The communication module can use wireless communication technologies such as Bluetooth, Wi-Fi, or LoRa; the specific choice depends on the actual usage environment and requirements.

[0038] In specific application scenarios, when the gate panel 1 falls unexpectedly due to connection component failure or other reasons, the drive limit pin 4 extends horizontally along the guide groove to the side of the gate panel 1. The extended limit pin 4 enters the semi-circular groove at the top of the support plate 5 and contacts the semi-circular shock-absorbing rubber block. Through the cooperation between the limit pin 4 and the groove, the falling movement of the gate panel 1 is effectively stopped. The setting of the shock-absorbing rubber block not only reduces the impact force when the limit pin 4 contacts the groove, but also reduces the wear of the device during long-term use, extending its service life.

[0039] The accelerometer of alarm device 6 monitors the movement of gate panel 1 in real time. When an abnormal drop is detected, the control board immediately triggers an alarm signal and sends the alarm information to the remote monitoring terminal via the communication module. Simultaneously, indicator lights or mechanical indicators on gate panel 1 visually display the extension status of limit pin 4, reminding operators to handle the situation promptly. For example, in water conservancy projects, when gate panel 1 unexpectedly drops due to flood impact or other reasons, this device can prevent the gate panel 1 from falling uncontrollably, ensuring the safety of engineering facilities and personnel.

[0040] The technical solution of this embodiment achieves effective protection against accidental fall of the gate panel 1 by precisely matching the hydraulically driven limit pin 4 with the semi-circular groove of the support plate 5. The limiter 3 and the support plate 5 have a reasonable structural design and a stable connection, which can significantly improve the safety performance of the integrated gate. At the same time, the device has a simple structure, reliable operation, and low maintenance cost, and has high practical value and application prospects.

[0041] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
