Description

Technical Field

[0001] This utility model relates to the technical field of conductive rails, and in particular to a safety protection and control device for conductive rails. Background Technology

[0002] With the rapid development of urban rail transit, conductive rails, as an important component of power supply systems for subways and light rails, are widely used in train traction power supply systems. Conductive rails are usually arranged beside or between tracks and are characterized by high voltage, large current, and complex operating environment. Once abnormal situations such as personnel accidentally entering, foreign objects intruding, or equipment overheating occur, they can easily cause safety accidents such as electric shock, short circuit, or even fire, seriously threatening personnel safety and normal equipment operation.

[0003] Currently, the safety protection of conductive rails mainly relies on traditional physical isolation measures and manual inspection methods. These traditional protection methods lack real-time monitoring capabilities, making it difficult to detect potential safety hazards in a timely manner, resulting in delayed responses and an inability to achieve all-weather, dynamic management of the operating status of conductive rails.

[0044] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0045] like Figures 1 to 5 As shown;

[0046] An embodiment of the present invention provides a safety protection control device for a conductive rail, comprising:

[0047] The protective housing 1 is the basic load-bearing structure of the entire safety protection and control equipment, and is installed on the side of the conductive rail;

[0048] The detection mechanism 2 is the core monitoring unit of this utility model. It is set on the protective shell 1 through the support mechanism 3 and is used to detect objects that approach or intrude into the dangerous area.

[0052] Temperature sensor, attached to the surface of conductive rail;

[0053] The audible and visual alarm module is used to issue an audible and visual warning when the detection mechanism 2 is triggered;

[0054] The control unit 4 is the core of the entire device. It is integrated into the protective housing 1 and electrically connected to the detection mechanism 2. The control unit 4 also integrates a wireless communication module, which is used to send the device status information to the remote monitoring terminal.

[0055] The monitoring mechanism 5 is installed on the support mechanism 3 and is used for video monitoring of the conductive rail area. The monitoring mechanism 5 is electrically connected to the control unit 4.

[0056] By adopting the above technical solution, the protective shell 1 serves as the basic load-bearing structure, providing a stable installation foundation for each component. The proximity sensor in the detection mechanism 2 can detect the distance between the object and the conductive rail in real time, the current sensor monitors the current status of the power supply circuit, and the temperature sensor senses the surface temperature of the conductive rail in real time. Multi-dimensional detection ensures that dangerous situations are detected in a timely manner. When an abnormality is detected, the audible and visual alarm module immediately issues a warning. The control unit 4, as the core, is electrically connected to the detection mechanism 2 and sends the equipment status information to the remote monitoring terminal through the wireless communication module to achieve remote real-time monitoring. The monitoring mechanism 5 performs video monitoring of the conductive rail area, further enhancing the visual management of the on-site situation. The overall structure takes into account the functions of real-time detection, timely warning, remote communication, and video monitoring, comprehensively improving the safety of conductive rail operation, reducing the risk of safety accidents, and ensuring the safety of personnel and equipment.

[0057] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the support mechanism 3 includes:

[0058] Mounting shaft 31 is rotatably mounted in the shaft hole of protective housing 1, and assembly part 32 is threadedly mounted on the top end of mounting shaft 31;

[0059] The extension column 33 is slidably connected to the shaft cavity of the mounting shaft 31 and the through hole of the assembly 32, respectively;

[0060] Mounting column 34 is coaxially rotatably mounted on extension column 33, and detection mechanism 2 is mounted on mounting column 34;

[0061] The lifting mechanism 35 is installed inside the protective housing 1, and the lifting mechanism 35 is connected to the extension column 33.

[0062] Adjustment mechanism 36 is installed inside the protective housing 1, and adjustment mechanism 36 is connected to mounting shaft 31.

[0063] In this embodiment, the mounting shaft 31 is rotatably mounted in the shaft hole of the protective housing 1. With the help of the adjustment mechanism 36, it can drive the extension column 33 and the mounting column 34 to rotate, thereby achieving horizontal adjustment of the detection direction. The lifting mechanism 35 cooperates with the extension column 33 and can drive the extension column 33 to slide along the shaft cavity of the mounting shaft 31 and the through hole of the assembly 32, thereby achieving lifting and lowering adjustment of the detection height. The assembly 32 is threadedly connected to the mounting shaft 31 and is used to control the range of motion of the extension column 33 and the mounting shaft 31. It also facilitates the disassembly and assembly of the structure. The overall structure can flexibly adjust the position, height and angle of the detection mechanism 2 according to the actual installation environment of the conductive rail, ensuring that the detection range accurately covers the dangerous area and enhancing the adaptability and detection reliability of the equipment to different scenarios.

[0064] As a preferred embodiment of the above technical solution, such as Figures 3 to 5 As shown, the lifting mechanism 35 includes:

[0065] Servo motor 35a is installed inside the protective housing 1, and drive shaft 35b is coaxially mounted on the output end of servo motor 35a.

[0066] The transmission component 35c is coaxially rotatably mounted on the extension column 33. The transmission component 35c is connected to the mounting shaft 31 through an internal thread. The transmission component 35c is slidably connected along the length of the drive shaft 35b. The drive shaft 35b drives the transmission component 35c to rotate.

[0067] In this embodiment, the servo motor 35a provides stable power, and the drive shaft 35b drives the transmission component 35c to rotate. The transmission component 35c is threaded with the mounting shaft 31 and slides along the drive shaft 35b. When rotating, it moves axially, thereby driving the extension column 33 to rise and fall smoothly and accurately adjust the height position of the detection mechanism 2 and the monitoring mechanism 5. This structure has smooth transmission and high adjustment accuracy, and can be flexibly adjusted according to the actual height of the conductive rail and the detection requirements to ensure accurate coverage of the detection range.

[0068] As a preferred embodiment of the above technical solution, such as Figures 3 to 4 As shown, the adjustment mechanism 36 includes:

[0069] A reciprocating motor 36a is installed inside the protective housing 1, and a drive gear 36b is coaxially mounted on the output end of the reciprocating motor 36a.

[0070] Driven gear 36c is coaxially mounted on mounting shaft 31, and driven gear 36c meshes with driving gear 36b.

[0071] The reciprocating motor 36a rotates in one direction, driving the mounting shaft 31 to rotate 360°.

[0072] In this embodiment, the reciprocating motor 36a provides power, and the driving gear 36b at its output end meshes with the driven gear 36c on the mounting shaft 31, which can drive the mounting shaft 31 to rotate smoothly. The unidirectional rotation can drive the mounting shaft 31 to achieve 360° rotation, thereby driving the detection mechanism 2 and the monitoring mechanism 5 to perform all-round horizontal adjustment through the extension column 33 and the mounting column 34. This ensures that the detection range covers the dangerous area of ​​the conductive rail without blind spots, and prevents the signal line from winding due to misalignment, ensuring the stability of long-term operation and improving the adaptability of the equipment to complex scenarios.

[0073] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, a through hole is provided on the mounting shaft 31;

[0074] In this embodiment, the through hole on the mounting shaft 31 provides a hidden wiring channel for the signal line between the detection mechanism 2 and the control unit 4, avoiding the line from being exposed to the outside environment for wear or interference, and ensuring the stability and safety of the electrical connection.

[0075] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, an isolation member 6 is provided inside the protective housing 1. The isolation member 6 is rotatably connected to the mounting shaft 31, and the lifting mechanism 35 is located inside the isolation member 6.

[0076] In this embodiment, the isolation component 6 inside the protective housing 1 independently separates the lifting mechanism 35 into the internal space, preventing it from contacting signal lines, etc., and eliminating structural interference or signal interference during operation.

[0077] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, monitoring unit 5 includes:

[0078] Mounting plate 51 is provided with at least one retaining ring 52, which is fitted onto mounting post 34;

[0079] Bolt 53 passes through the connecting hole of retaining ring 52, and nut 54 is installed on bolt 53;

[0080] Camera 55 is mounted on mounting plate 51;

[0081] In this embodiment, the fixing ring 52 of the mounting plate 51 is fitted onto the mounting post 34, and the mounting plate 51 can be firmly locked in position with the bolts 53 and nuts 54 to ensure stable installation of the camera 55 and avoid displacement caused by vibration or operation of the adjustment mechanism 36.

[0082] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
