Description

Technical Field

[0001] This utility model belongs to the field of railway environmental monitoring, and in particular relates to a device for fixing a flow sensor for railway slopes. Background Technology

[0002] Railway transport safety is highly dependent on weather conditions, especially heavy rainfall. Continuous rainfall not only increases the load on track facilities, but more dangerously, it can also cause surface runoff on railway shoulders and slopes. This runoff can erode the roadbed, hollow out the ballast, and in severe cases, lead to major accidents such as slope collapses and line interruptions.

[0003] Currently, railway meteorological monitoring relies heavily on traditional rain gauges and anemometers installed at fixed locations. These devices can only provide rainfall data at specific points and cannot reflect the convergence and flow of rainwater on complex roadbed slopes, which can lead to slope runoff and even the risk of slope collapse. Therefore, there is an urgent need for a device to monitor railway slope runoff. Utility Model Content

[0004] The purpose of this utility model is to provide a device for fixing a flow sensor on a railway slope, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model for fixing a flow sensor on a railway slope is as follows: A device for fixing a flow sensor on a railway slope includes two connecting seats, a connecting rod rotatably positioned between the two connecting seats, and multiple mounting seats distributed on the connecting rod, each mounting seat housing a flow sensor. Each mounting seat includes a bracket mounted on the connecting rod, with mounting holes for the flow sensor to pass through, and a limiting member for fixing the flow sensor. The connecting seat includes a base and a vertically mounted column on the base, an adjusting mechanism mounted on the column, a support block rotatably mounted on the adjusting mechanism, and a traction frame rotatably mounted on the support block, the traction frame being connected to the connecting rod.

[0006] Furthermore, the adjustment mechanism includes an adjusting bolt vertically threaded onto the column, and a threaded hole on the column for threaded connection of the adjusting bolt. The support block is rotatably connected to the top of the adjusting bolt. A crossbar is provided at the top of the adjusting bolt.

[0007] Furthermore, the limiting component includes a top plate that is slidably disposed in the mounting hole, and the inner side wall of the top plate is provided with a rubber pad, and a second fastening bolt is threadedly connected to the bracket, and the second fastening bolt passes through the mounting hole and is rotatably connected to the top plate.

[0008] Furthermore, the connecting rod includes a first arm, multiple second arms and a third arm, with the second arms located between the first and third arms. The arms are detachably connected, and the first and third arms are rotatably connected to two connecting seats respectively.

[0009] Furthermore, the first and third arms are respectively provided with a male head and a female groove at their relatively close ends, and each of the second arms is also provided with a male head and a female groove at both ends. The male head includes a insertion rod and spring plates inclined on the free ends of the two side walls of the insertion rod. The female groove includes a insertion hole for inserting the insertion rod, and a first sliding groove adapted to the spring plate and extending outward is formed on the two side walls of the insertion hole. A second sliding groove adapted to the spring plate and extending outward is also formed on the first sliding groove. The first and second sliding grooves combine to form a Z-shaped groove. A push rod is laterally slidable within each of the second sliding grooves, and the push rod passes through the second sliding groove and extends outward. A limiting piece is provided at the inner end of the push rod, and a screw is provided at the outer end of the push rod. The screw is threadedly connected to the push rod, and the screw nut is larger than the diameter of the push rod.

[0010] Furthermore, multiple mounting frames are slidably provided on the connecting rod, and each mounting frame has a groove for the connecting rod to pass through and slide.

[0014] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a flow sensor fixing device for railway slopes.

[0015] like Figures 1 to 5 As shown, this utility model discloses a flood sensor fixing device for railway slopes, comprising two connecting seats, a connecting rod rotatably positioned between the two connecting seats, and multiple mounting seats distributed on the connecting rod, each mounting seat equipped with a flood sensor (existing technology). The flood sensor is connected to a terminal display screen, which transmits the monitored rainwater flow velocity and flow rate data to the terminal display screen for viewing. Users can also manually set preset values ​​for the flood sensor. When the flow velocity or flow rate reaches the preset value, the terminal will issue an alarm to remind personnel to promptly check the slope condition and take emergency measures. In use, the two connecting seats of the fixing device can be fixed to the road shoulder and the roadbed at the bottom of the slope, respectively, with the connecting rod parallel to the slope, and then each flood sensor can be installed on the connecting rod. Because the location of the overflow is uncertain, multiple overflow sensors are installed on the connecting rod via mounting bases. These sensors enable multi-point monitoring of the slope. When overflow occurs on the slope, the overflow will flow through the overflow sensor at its corresponding location. The overflow sensors that come into contact with the overflow will then monitor the flow rate and volume of the rainwater and send the monitoring results to the terminal display. At the same time, an alarm will be issued to remind the staff that an overflow has occurred.

[0016] Specifically, the connecting seat includes a base 1 and a column 2 vertically mounted on the base 1. The base 1 has a through hole, through which anchor bolts are passed to securely fix the base 1 to the ground. An adjustment mechanism is also provided on the column 2, and a support block 3 is rotatably mounted on the adjustment mechanism. A traction frame 8 is rotatably mounted on the support block 3 and connected to the connecting rod. Because the slope is inclined, one connecting seat is fixed to the shoulder at the top of the slope, and the other connecting seat is fixed to the roadbed at the bottom of the slope. For ease of understanding, the connecting seat fixed to the shoulder is named the first connecting seat, and the other connecting seat is named the second connecting seat. After the first and second connecting seats are fixed, the connecting rod is inclined relative to the ground. To ensure the connecting rod is parallel to the slope, the height of both ends of the connecting rod can be adjusted using the adjustment mechanism on each connecting seat, making the connecting rod parallel to the slope. The distance between the connecting rod and the slope can also be adjusted using the adjustment mechanism, allowing for adjustment of the distance between the flow sensor mounted on the connecting rod and the slope.

[0017] like Figure 2 As shown, the adjustment mechanism includes an adjusting bolt 7 vertically threaded onto the column 2, and a threaded hole on the column 2 for threaded connection of the adjusting bolt 7. A support block 3 is rotatably connected to the top of the adjusting bolt 7. The threaded connection between the adjusting bolt 7 and the column 2 ensures stable connection and allows for stepless adjustment of the column 2 and the support block 3. In use, simply rotating the adjusting bolt 7 moves it upwards from the threaded hole in the column 2. At this time, the support block 3 on the adjusting bolt 7 also raises the connecting rod on the traction frame 8. Similarly, rotating the adjusting bolt 7 in the opposite direction moves it inwards into the column 2, causing the support block 3 on the adjusting bolt 7 and one end of the connecting rod mounted on the support block 3 via the traction frame 8 to descend. By adjusting the adjustment mechanisms on the first and second connecting seats in this way, the height of the connecting rod can be adjusted. To facilitate rotation of the adjusting bolt 7, a crossbar is provided at the top of the adjusting bolt 7.

[0018] like Figure 1 and Figure 3 As shown, the mounting base includes a bracket 12 mounted on the connecting rod, and the bracket 12 has a mounting hole 13 for the flow sensor to pass through. A limiting component for fixing the flow sensor is also provided on the bracket 12. The limiting component facilitates the installation and removal of the flow sensor on the bracket 12, saving installation and removal time, and also facilitates future replacement and maintenance of the flow sensor, making it more practical. Specifically, the bracket 12 is Z-shaped, and the mounting hole 13 is located on the base plate of the Z-shaped bracket 12. This allows the flow sensor on the bracket 12 to be positioned on one side of the connecting rod, providing ample space for installation and removal, resulting in higher installation and removal efficiency.

[0019] like Figure 4As shown, the limiting component includes a top plate 14 slidably disposed within the mounting hole 13, with a rubber pad 15 on the inner side wall of the top plate 14. A second fastening bolt 16 is threaded onto the bracket 12, and the second fastening bolt 16 passes through the mounting hole 13 and is rotatably connected to the top plate 14. When installing the flow sensor, simply insert the flow sensor into the mounting hole 13, adjust its installation height to an appropriate position, and then rotate the second fastening bolt 16. The second fastening bolt 16 drives the top plate 14 and the rubber pad 15 on the top plate 14 to move towards the flow sensor. Once the top plate 14 has sufficient clamping force on the flow sensor, the rotation of the second fastening bolt 16 can be stopped. The operation is simple and convenient. The rubber pad 15 prevents the second fastening bolt 16 from causing excessive clamping force on the flow sensor, which could damage the flow sensor.

[0020] Preferably, multiple mounting frames 9 are slidably provided on the connecting rod, and each mounting frame 9 has a groove for the connecting rod to pass through and slide. A bracket 12 for mounting the flow sensor is mounted on the mounting frame 9. A first fastening bolt 11 is threaded onto the top surface of the mounting frame 9 and engages with the connecting rod. The first fastening bolt 11 secures the mounting frame 9 to the connecting rod, thus fixing the position of the bracket 12 mounted on the connecting rod via the mounting frame 9. Furthermore, the mounting frame 9 and the connecting rod are slidably connected, allowing the flow sensor on the bracket 12 to adjust its position according to different slope conditions, thereby achieving accurate monitoring of slope flow. Alternatively, the mounting frames 9 can be evenly distributed on the connecting rod, and multiple flow sensors can be used to monitor different points on the slope to understand the impact of rainfall on the slope.

[0021] As another preferred embodiment, the connecting rod includes a first arm 4, multiple second arms 5, and a third arm 6. The second arms 5 are located between the first arms 4 and the third arms 6, and the arms are detachably connected. The first arms 4 and the third arms 6 are rotatably connected to two connecting seats, respectively. Each arm support 12 is detachably connected, and since there are multiple second arms 5, when the slope is steep, an appropriate number of second arms 5 can be combined according to the slope length, and the combined second arms 5 can be connected to the first arms 4 and the second arms 6, thus improving the practicality of the device. Furthermore, the detachable connection between the arms allows them to be disassembled during transportation, saving space and facilitating storage.

[0022] Specifically, the first arm 4 and the third arm 6 are respectively provided with male and female grooves at their relatively close ends, and each of the second arms 5 is also provided with male and female grooves at both ends. This means that the first arm 4 and the third arm 6 can be connected. Furthermore, if the length of the slope makes the connection between the first arm 4 and the third arm 6 insufficient, an appropriate number of second arms 5 can be connected between the first arm 4 and the third arm 6, making it highly practical. Figure 5 As shown, the male connector includes a insertion rod 21 and spring plates 22 inclined on the free ends of the two side walls of the insertion rod 21. The female connector includes a socket 17 for inserting the insertion rod 21, and first grooves 18 that fit the spring plates 22 and extend outward on the two side walls of the socket 17. Second grooves 19 that fit the spring plates 22 and extend outward are also formed on the first grooves 18. The first grooves 18 and the second grooves 19 combine to form a Z-shaped groove. When the insertion rod 21 is connected to the socket 17, the arm with the insertion rod 21 is pushed towards the arm that drives the socket 17. When the outer edge of the spring plate 22 contacts the first groove 18, the spring plate 22 is compressed and its free end moves closer to the insertion rod 21 as the two arms approach. When the plug is fully inserted into the socket 17, the free end of the spring plate 22 passes over the first slide groove 18. Under the action of elastic potential energy, the free end of the spring plate 22 will unfold, and the spring plate 22 will then be stuck in the second slide groove 19, thus realizing the connection of the two support arms.

[0023] To facilitate the disassembly of the two connected support arms, a push rod 20 is laterally slidable within each of the second slide grooves 19, extending outwards through the second slide groove 19. A limiting piece is located at the inner end of the push rod 20, and a screw is located at the outer end of the push rod 20. The screw is threadedly connected to the push rod 20, and the screw nut is larger than the diameter of the push rod 20. The threaded connection between the screw and the push rod 20 facilitates the assembly and disassembly of the push rod 20 on the support arms. When it is necessary to disassemble the connected support arms, two screws can be pressed simultaneously. The two screws will press the free ends of the spring plates 22 closer to the insertion rod 21, making the distance between the two spring plates 22 smaller than the distance between the two first slide grooves 18. Then, by pulling the two support arms, the two connected support arms can be disassembled. It should be noted that the push rod 20 is located at the connection between the first slide groove 18 and the second slide groove 19. When the spring plate 22 enters the second slide groove 19, the release of the elastic potential energy of the spring plate 22 will push the push rod 20 in the second slide groove 19 to move outward, so that the push rod 20 can be pressed when the support arm is disassembled.

[0024] like Figure 3 As shown, a clearance groove 10 is also provided on the inner wall of the slide corresponding to the position of the top rod 20 and the screw. The depth of the clearance groove 10 is the same as the length of the top rod 20 when the spring plate 22 pushes it, so that the mounting frame 9 can move on each support arm.

[0025] Working principle: Adjust the length of the connecting rod to an appropriate length according to the slope length. Then, adjust each mounting frame 9 to the appropriate position and fix it to the connecting rod using the first fastening bolt 11. At the same time, install the flow sensors on each bracket 12 using limiting parts. Finally, use anchor bolts to fix the first connecting seat and the second connecting seat to the shoulder and the roadbed respectively. Use the adjustment mechanism to adjust the connecting rod to a parallel state with the slope, and adjust the distance between each flow sensor and the slope to an appropriate height.
