Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology and relates to an integrated gate position and limit position acquisition device. Background Technology

[0002] Integrated gate position and limit switch acquisition devices are key equipment used in water conservancy, power, and municipal engineering fields to collect gate position information and limit switch status. Their working principle is as follows: The mechanical displacement of the gate is converted into electrical or digital signals to obtain gate position information, and limit switches and other devices are used to trigger signals to determine the limit switch status. In practical applications, integrated gate position and limit switch acquisition devices typically include the following key components:

[0003] 1. Mechanical structure: including gear set, limit switch slide, micro limit switch baffle and base, etc., responsible for accurately transmitting the movement of the gate and converting it into a detectable signal.

[0004] 2. Electrical Components: Composed of electrical components such as PLC, linear displacement sensor, and micro limit switch, which realize the functions of signal processing, transmission and control.

[0005] Currently, various types of gate position and limit switch acquisition devices are available on the market to achieve effective control and monitoring of gates. Some use contact-type acquisition devices, such as mechanical limit switches and resistive displacement sensors; others use non-contact acquisition devices, such as infrared, ultrasonic, and laser sensors; and still others have enhanced their anti-interference capabilities and stability through optimized structural design.

[0006] However, the aforementioned existing devices still have the following problems:

[0007] 1. Existing gate position and limit switch acquisition devices are insufficient to meet the high-precision requirements of certain scenarios. For example, some devices have large measurement errors in the 0-10m range, failing to reach the high-precision standard of ±1cm, and thus cannot accurately control and monitor the gate opening.

[0008] 2. Most devices are inconvenient to install, cannot flexibly adapt to different gate structures and installation environments, and are difficult to maximize the use of the stroke within a limited internal stroke range, making them unsuitable for the vast majority of gate openings.

[0009] 3. Low level of informatization and limited communication methods make it difficult to meet the needs of automated control, affecting the service life and reliability of equipment. Utility Model Content

[0010] To address the aforementioned issues, this utility model proposes an integrated gate position and limit position acquisition device. It employs an innovative mechanical structure design to improve the device's accuracy, ease of installation, applicability, and reliability, thereby meeting the practical needs of water conservancy automation and other applications.

[0011] To achieve the above objectives, the technical solution of this utility model is as follows:

[0033] The technical solution provided by this utility model will be described in detail below with reference to specific embodiments. It should be understood that the following specific embodiments are only used to illustrate this utility model and are not intended to limit the scope of this utility model.

[0034] Please see Figures 1 to 6 The integrated gate and limit acquisition device provided by this utility model includes a gate plate 1, and a door plate that can move up and down is provided inside the gate plate 1. The up and down movement mechanism of the door plate is the same as that of the prior art, and will not be described again in this utility model. Figure 2 As shown, a connecting plate 2 is provided on the left side of the gate 1. The connecting plate 2 is fixedly connected to the door panel inside the gate 1, and a controller 3 is fixedly installed on the left surface of the connecting plate 2. The controller 3 receives signals from the monitor, baffle, etc., and can also make decisions based on these signals to drive the actuators such as cylinders. The controller is a common core processing and control component in this field. A slot 5 is provided on the left surface of the gate 1. A connecting block 10 is fixedly connected in the slot 5. A right angle gear 11 is rotatably connected in the connecting block 10. A right angle gear 12 is rotatably connected to the rear surface of the gate 1. A connecting rod is fixedly connected to the front surface of the right angle gear 12. The right angle gear 11 is fixedly connected to the connecting rod. A set of gear grooves 16 is provided on the right surface of the connecting plate 2. The set of gear grooves 16 is sawtooth-shaped and can be movably engaged with the right angle gear 11, that is, the right angle gear 11 can roll along the gear grooves 6. A bracket 17 is fixedly installed on the rear surface of the gate 1. A right-angle gear 12 is rotatably connected to the bracket 17. An encoder 18 is installed at the rotating shaft inside the bracket 17. During operation, the gate's movement drives the connecting plate 2 to move as well. This movement of the connecting plate 2 drives the engaged right-angle gear 11 to rotate. The rotation of the right-angle gear 11 drives the fixed right-angle gear 12 to rotate as well. The monitor 18 monitors the rotation of the right-angle gear 12. The monitor can be an encoder, which is associated with the rotating gear to obtain encoder data reflecting the gear rotation. Through the meshing of the gear slot in the connecting block with the right-angle gear 1, and the transmission between the right-angle gears 1 and 2, the gate's displacement can be indirectly obtained, thus determining the gate's opening position. This invention, through a precise transmission ratio between the gears, converts the gate's linear motion into gear rotation, thereby amplifying minute displacement changes and improving the sensitivity and accuracy of gate position data acquisition, solving the problem of low accuracy in traditional devices.

[0035] A slider 15 is provided in front of the connecting plate 2. Two limiting rods 9 are fixedly connected to the surface of the connecting plate 2. Both limiting rods 9 are movably connected to the slider 15. The slider 15 has two sliding holes. The slider 15 is fitted onto the limiting rods through the sliding holes, and the limiting rods play a limiting and guiding role for the slider. Two sliding grooves 8 are opened on the front surface of the gate plate 1. Both sliding grooves 8 are movably connected to the slider 15. A baffle 6 is fixedly installed on the front surface of the gate plate 1. The baffle 6 serves as a triggering mechanism and is located below the sliding grooves. The gate plate 1 (excluding the movable gate) is movably connected to the connecting plate 2. The connecting plate 2 is fixedly connected to the door panel provided inside the gate plate 1. A limiting block 19 is movably engaged inside the slider 15. A cylinder 7 is fixedly installed on the front surface of the slider 15. The piston of the cylinder 7 is fixedly connected to the limiting block 19. A set of limiting grooves 4 are opened on the front surface of the gate plate 1. All of these limiting grooves 4 can engage with the limiting blocks 19. In this example, the limiting blocks and limiting grooves are provided with serrations of matching size. In terms of installation, the integrated design makes the overall structure of the device more compact, reducing installation steps and required space, and solving the problem of inconvenient installation. A set of internally threaded circular grooves 13 are formed on the front surface of the connecting plate 2. Each of these grooves 13 is threadedly engaged with two hexagonal socket screws. Two fixing plates 14 are fixedly connected to the left surface of the slider 15, and both fixing plates 14 are threadedly engaged with the aforementioned hexagonal socket screws. A rectangular groove 20 is formed on the surface of the slider 15 facing the connecting plate. The rectangular groove 20 is movably engaged with the limiting block 19. When the connecting plate 2 moves downward, its lower end will abut against the baffle 6. A contact sensor, such as a microswitch, can be installed at the baffle 6. The contact of the microswitch should be on the moving path of the connecting plate or be able to be triggered by the deformation of the baffle. When the lower end of the connecting plate abuts against the baffle, and the baffle 6 is subjected to external force generated by the displacement of the connecting plate 2, the microswitch will convert the pressure on the baffle into an electrical signal, and send the output switching signal to the controller 3 for processing. After receiving the signal, controller 3 will drive cylinder 7 to start. Cylinder 7 will then move the fixed limit block 19, which moves towards the connecting plate and engages with a set of limit grooves 4 on the front surface of gate 1. This limits and fixes the connecting plate 2. Since the connecting plate 2 is fixedly connected to the gate panel inside gate 1, the gate panel is also limited and fixed. Turning the two Allen screws will loosen the limit fixing of slider 15, allowing slider 15 to slide on the connecting plate 2. Its position can be adjusted according to the gate height and actual needs.

[0036] The working principle of this utility model is as follows:

[0037] Initially, there is a certain distance between the limit block and the limit groove, and they are not locked together. When the device is running, the movement of the door plate drives the connecting plate 2 to move together. The movement of the connecting plate 2 drives the locked right angle gear 11 to rotate. When the right angle gear 11 rotates, it drives the fixed right angle gear 12 to rotate together. A monitor 18 is set on the surface of the right angle gear 12 for monitoring. Through the precise transmission ratio between the gears, the linear motion of the gate is converted into the rotation of the gears, thereby amplifying the small displacement changes. The signal collected by the monitor is transmitted to the controller. When the connecting plate 2 moves downward, its lower end will abut against the baffle 6. When the baffle 6 is subjected to the external force generated by the displacement of the connecting plate 2, it will transmit a sensing signal to the controller 3. Upon receiving the signal, the controller 3 will drive the cylinder 7 to start. The start of the cylinder 7 will drive the fixed limit block 19 to move together. The limit block 19 moves forward and will engage with a set of limit grooves 4 opened on the front surface of the gate 1. At this time, the connecting plate 2 is limited and fixed. The connecting plate 2 is fixedly connected to the door panel inside the gate 1, and the door panel is limited and fixed. The controller's drive of the cylinder after receiving the sensing signal is a common trigger control process in this field. There is a large amount of software available on the market that can be used, and no software modification is required.

[0038] This invention combines a traditional gate position gauge and a limit switch into an integrated device. The variable ratio gear, baffle limit, and cylinder work in concert to achieve comprehensive, high-precision data acquisition and limit control of the gate position. This integrated design not only reduces the size and complexity of the device but also improves its stability and reliability by optimizing the connections and communication between components. The limit block design provides redundant protection to prevent over-positioning due to a single-point failure of the gate limit. The controller has a pre-set RS485 communication interface to support remote diagnostics, reducing downtime. Overall error control of ±1cm (0-10m travel) and 0.01mm-level sensor accuracy far exceed traditional mechanical / electronic limit devices. Mechanical life is ≥100,000 cycles, and mean time between failures (MTBF) is ≥25,000 hours, reducing maintenance frequency. The sealed structure, waterproof design, and corrosion-resistant materials make it suitable for harsh environments common in water conservancy projects, such as humidity, dust, and large temperature differences. Mechanical triggering does not require a power supply, and its anti-electromagnetic interference capability is significantly better than that of electronic limit switches.

[0039] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
