Description

Technical Field

[0001] The utility model relates to the technical field of early warning devices, in particular to an early warning device for water accumulation outside an urban rail transit station. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. With the diversified development of train and railway technology, rail transit has shown more and more types, not only covering long-distance land transportation, but also widely used in medium and short-distance urban public transportation. When water accumulates on rail transit roads, detection and early warning devices are needed to raise the alarm. The water accumulation early warning device is a device used to monitor and warn of water accumulation. It monitors the water level changes in a specified area in real time through sensors or monitoring devices. Once the water level exceeds the set safety threshold, the early warning device will sound an alarm so that timely measures can be taken to avoid or reduce the damage or danger that may be caused by water accumulation. It can effectively prevent problems such as flooding, damage or traffic jams caused by water accumulation, and improve the ability of urban management and safety prevention;

[0003] Traditional waterlogging warning devices usually consist of water level sensors, data acquisition units and alarm systems. Water level sensors are installed in potential waterlogging areas to monitor water level changes and transmit data to the data acquisition unit. The data acquisition unit is responsible for real-time analysis and processing of the collected data. Once the water level exceeds the set threshold, the alarm system is triggered to send out a warning signal.

[0004] However, the structure of the traditional water accumulation warning device is relatively simple, and its overall shell is usually relatively closed, and the device cannot be quickly disassembled or opened and closed, which makes it difficult to conveniently maintain or repair the internal components of the device. When the sensor or data processing unit needs to be adjusted, replaced or repaired, more time and labor are required. Therefore, a water accumulation warning device outside an urban rail transit station is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 and Figure 3 The utility model provides an embodiment: an early warning device for water accumulation outside an urban rail transit station, comprising an outer shell 1, an opening and closing door 2 is rotatably connected inside the outer shell 1, a support plate 3 is fixedly connected to one side of the opening and closing door 2, a fixing frame 4 is fixedly connected to one side of the outer shell 1, a clamping hole 5 is opened inside the fixing frame 4, a fixing ring 6 is fixedly connected to one side of the support plate 3, a limiting column 7 is slidably connected inside the fixing ring 6, the limiting column 7 is slidably connected inside the clamping hole 5, a sleeve ring 8 is fixedly connected to the outer wall of the limiting column 7, a first spring 9 is sleeved on the outer wall of the limiting column 7, one end of the first spring 9 is fixedly connected to the inside of the sleeve ring 8, the other end of the first spring 9 is fixedly connected to the inside of the fixing ring 6, a lever 10 is fixedly connected to the outer wall of the sleeve ring 8, a limiting plate 11 is fixedly connected to one side of the support plate 3, the lever 10 is slidably connected inside the limiting plate 11, and a monitoring component is arranged inside the outer shell 1, the monitoring component is used to monitor water accumulation.

[0034] Specifically, when the monitoring component inside the outer shell 1 needs to be maintained, the operator first pulls the lever 10, which will drive the ring 8 to move. The movement of the ring 8 causes the internally connected limit column 7 to slide out from the inside of the fixing frame 4, thereby allowing the opening and closing door 2 to rotate and open inside the outer shell 1. During the closing process of the opening and closing door 2, the limit column 7 on one side contacts the fixing frame 4, causing the limit column 7 to slide inside the fixing ring 6. This action causes the limit column 7 to drive the ring 8 connected to the outer wall to move, and the ring 8 contracts by squeezing the first spring 9 connected inside. When the opening and closing door 2 is fully closed, the first spring 9 releases its contraction energy and pushes the ring 8 to reset. The resetting of the ring 8 causes the limit column 7 to slide into the card hole 5 inside the fixing frame 4, thereby completing the fixation, ensuring that the early warning device can be quickly opened and safely closed when maintenance is required, thereby improving the convenience and efficiency of operation.

[0035] Reference Figure 1 and Figure 2 The monitoring component includes a water level column 12, which is fixedly connected to the inside of the outer shell 1. A plurality of floats 13 are arranged on the outer wall of the water level column 12. A filter screen 15 is fixedly connected to the inside of the outer shell 1. Through holes 14 are opened inside the plurality of floats 13, and water level sensors are arranged inside the plurality of floats 13.

[0036] Specifically, during the monitoring process, the operator first sets a corresponding numerical value according to the expected warning height. When water accumulation occurs, the water first filters through the filter 15 and enters the outer shell 1. According to the change in water level, multiple floats 13 of different heights installed inside the outer shell 1 are gradually submerged. Once the accumulated water reaches a preset height, the water level sensor inside the submerged float 13 will detect the water level change and transmit the signal to the alarm above the outer shell 1. After receiving the signal, the alarm immediately sends out a warning signal, thereby achieving the effect of monitoring and early warning.

[0037] Reference Figure 4 and Figure 5 A mounting seat 16 is fixedly connected to the bottom of the outer shell 1, and a mounting pin 17 is slidably connected inside the mounting seat 16. A threaded column 18 is threadedly connected inside the mounting pin 17, and a handle 19 is fixedly connected to the top of the threaded column 18. A connecting column 20 is fixedly connected to the bottom of the threaded column 18. A cone head 22 is slidably connected to the outer wall of the connecting column 20. A second spring 21 is sleeved on the outer wall of the connecting column 20. The top of the second spring 21 is fixedly connected to the inside of the threaded column 18, and the bottom of the second spring 21 is fixedly connected to the inside of the cone head 22. A ball 23 is slidably connected to the inside of the mounting pin 17, and the ball 23 is in contact with the cone head 22.

[0038] Specifically, when the early warning device needs to be disassembled and assembled, the operator first places the mounting seat 16 at the bottom of the outer shell 1 at the predetermined installation position, and then inserts the mounting pin 17 to align it with the mounting seat 16 and the corresponding mounting hole in the ground. Then, by twisting the handle 19, the operator applies force to rotate the threaded column 18 inside the mounting pin 17. The threaded cooperation between the threaded column 18 and the mounting pin 17 causes the threaded column 18 to move, thereby driving the connecting column 20 and the second spring 21 connected at the bottom to move accordingly. The movement of the second spring 21 drives the cone head 22 connected at the bottom to start sliding on the outer wall of the connecting column 20. During the movement of the cone head 22, it applies pressure to the ball 23 inside the mounting pin 17, so that the ball 23 is forced to slide out of the outside of the mounting pin 17 and get stuck in the ground, completing the installation and fixing, ensuring the rapid disassembly and assembly of the early warning device, so that when the device position needs to be moved or replaced, the operation is simple and efficient, while ensuring a safe and stable fixing effect.

[0039] Working principle: When it is necessary to maintain the monitoring components inside the outer shell 1, first, the lever 10 is toggled to drive the collar 8 to move. The collar 8 is forced to drive the internally connected limit column 7 to slide out of the fixing frame 4, so that the opening and closing door 2 is rotated and opened inside the outer shell 1. Then, during the closing process of the opening and closing door 2, the limit column 7 on one side will contact the fixing frame 4, so that the limit column 7 is forced to slide inside the fixing ring 6. The limit column 7 is forced to drive the collar 8 connected to the outer wall to move, and the collar 8 is forced to squeeze the inner The first spring 9 connected to the upper part contracts. When the opening and closing door 2 and the outer shell 1 are completely closed, the first spring 9 unloads the force to rebound, thereby driving the ring 8 to reset. The ring 8 is forced to drive the limit column 7 to slide into the card hole 5 inside the fixing frame 4 to complete the fixation, thereby achieving the effect of facilitating the opening and closing of the early warning device. During the monitoring process, the corresponding value is first input according to the required early warning height. When water accumulation occurs, the accumulated water first enters the inner part of the outer shell 1 through the filtration of the filter screen 15. According to the height of the accumulated water, it will gradually submerge the outer shell. There are multiple floats 13 at different heights inside the outer shell 1. When the accumulated water reaches a preset numerical height, the water level sensor inside the float 13 at the corresponding height transmits a signal to the alarm above the outer shell 1, and sends out a warning signal. When the warning device needs to be disassembled and assembled, first, the mounting seat 16 at the bottom of the outer shell 1 is placed in the installation position, and then the mounting pin 17 is inserted into the mounting seat 16 and the corresponding mounting hole in the ground, and then the handle 19 is twisted to force the threaded column 18 to rotate inside the mounting pin 17. Through the threaded cooperation between the threaded column 18 and the mounting pin 17, the threaded column 18 moves, and the threaded column 18 is forced to drive the connecting column 20 and the second spring 21 connected at the bottom to move. The second spring 21 is forced to drive the cone head 22 connected at the bottom to move, and at the same time, the cone head 22 slides on the outer wall of the connecting column 20. During the movement of the cone head 22, the ball 23 inside the mounting pin 17 is squeezed, so that it is forced to slide out of the outside of the mounting pin 17 and be stuck in the ground to complete the fixation, thereby achieving the effect of easy disassembly and assembly of the warning device.
