Description

Technical Field

[0001] This application relates to the technical field of instruction transmitting devices, and more particularly, to a river backflow warning device. Background Art

[0002] In areas with a high degree of karst development, sinkholes or large karst spring outlets are connected to surface rivers. Due to the different recharge areas and hydrographic response processes of surface water and karst groundwater, surface water backflows into sinkholes or large karst spring outlets connected to the surface river during flood periods. A Chinese patent with the patent name of a river backflow monitoring and warning device and the application number 202222104687.6 has been publicly disclosed. Although this patent can achieve the monitoring and warning of river backflows, it needs to be fixed to the ground. For water-yielding sinkholes or large karst springs with water supply significance, the soil environment around them has poor compactness, which can easily cause the entire device to collapse or fall, ultimately resulting in the inability to achieve the long-term and normal warning work of river backflows. Utility Model Content

[0003] The purpose of this application is to provide a river backflow warning device, which solves the problem in the prior art that for water-yielding sinkholes or large karst springs with water supply significance, the device cannot be fixed around them, resulting in the inability to carry out the long-term river backflow warning work.

[0004] Technical Solution of This Application:

[0005] This application provides a river backflow warning device, including a support rod and a steering detection plate and a signal transmitter connected to the support rod. The lower end of the support rod is fixed in the underwater rock. The steering detection plate is in contact with the water flow. The signal transmitter is signal-connected to the steering detection plate. The signal transmitter is used to store and remotely send the change in the rotation direction of the steering detection plate to the emergency warning room.

[0006] Preferably, the support rod includes a working section and a fixed section connected below the working section. The fixed section is arranged in the underwater rock.

[0007] Preferably, a hemispherical warning cover is arranged at the top of the working section.

[0008] Preferably, there is a reflective strip above the warning cover.

[0009] Preferably, a water level detector signal-connected to the signal transmitter is also arranged on the working section. The water level detector is located between the warning cover and the steering detection plate.

[0010] Preferably, the length of the working section is 1 - 40 m, and the length of the fixed section is 1 - 500 m.

[0011] Preferably, the above signal transmitter is arranged within the working section.

[0012] The technical solution of this application has at least the following advantages and beneficial effects:

[0013] This application provides a river backflow warning device, which is provided with a support rod, a steering detection plate, and a signal transmitter. By monitoring the flow direction, it can play a warning role in the case of surface water backflow during the flood period. When the river water is in the critical state of backflow, the flow velocity of the river channel is very slow, and the flow direction changes back and forth. When the water flow direction changes, the rotation direction and rotation speed of the steering detection plate will change accordingly. The action and signal of this rotation direction change will be detected, stored, and remotely sent to the emergency warning room by the signal transmitter. Then, the emergency warning room can take corresponding measures in a timely manner according to the changes in the water flow, solving the problem in the prior art that for the water outlet pool or large karst spring with water supply significance, the device cannot be fixed around it, resulting in the inability to carry out long-term river backflow warning work.

[0017] Embodiment

[0018] Please refer to Figure 1 , this application provides a river backflow warning device, which includes a support rod and a steering detection plate 3 and a signal transmitter 8 connected to the support rod. The lower end of the support rod is fixed in the underwater rock 4. The steering detection plate 3 is in contact with the water flow 5. The signal transmitter 8 is signal-connected to the steering detection plate 3. The signal transmitter 8 is used to store and remotely send the change in the rotation direction of the steering detection plate 3 to the emergency warning room 9.

[0019] It should be noted that in the prior art, for the water outlet pool or karst spring with water supply significance, the compactness of the soil environment around it is poor, which is likely to cause the collapse or falling of the entire device, and finally lead to the inability to realize the early warning of river backflow for a long time and normally. In this embodiment, a support rod, a steering detection plate 3, and a signal transmitter 8 are provided. Through the monitoring of the flow direction, it can play a role in warning against surface water backflow during the flood period. Specifically, when it is in the critical state of backflow, the river flow velocity is very slow and the flow direction changes back and forth. When the flow direction of the water flow 5 changes, the rotation direction and rotation speed of the steering detection plate 3 will change accordingly. The movement and signal of this rotation direction change will be detected, stored, and remotely sent to the emergency warning room 9 by the signal transmitter 8. Then, the emergency warning room 9 can take corresponding measures in a timely manner according to the changes in the water flow 5. Further, to ensure that the device provided in this embodiment realizes the early warning of river backflow, the steering detection plate 3 is adjusted so that it can always contact the water flow 5. Still further, to ensure that the device provided in this embodiment can realize the early warning of river backflow for a long time and normally, the lower end of the support rod is fixed in the underwater rock 4. This embodiment solves the problem in the prior art that for the water outlet pool or karst spring with water supply significance, the device cannot be fixed around it, resulting in the inability to carry out the long-term early warning of river backflow.

[0020] Preferably, the support rod includes a working section 1 and a fixed section 2 connected below the working section 1, and the fixed section 2 is arranged in the underwater rock 4. Specifically, the strength and hardness of the working section 1 are both greater than those of the fixed section 2, so that it can be ensured that the working section 1 can always work normally under the long-term continuous contact of the water flow 5.

[0021] Preferably, a hemispherical warning cover 6 is arranged at the top of the working section 1. There is a reflective strip above the warning cover 6. By arranging the hemispherical warning cover 6 and setting a reflective strip on it, the staff can find the location of this device in the fastest time, which is convenient for the maintenance, disassembly, installation, and replacement of the device.

[0022] Preferably, a water level detector 7 signal-connected to the signal transmitter 8 is also arranged on the working section 1, and the water level detector 7 is located between the warning cover 6 and the steering detection plate 3. By providing the water level detector 7, the water level data can be monitored in real time, so that the staff can not only understand the condition of the water flow 5 through the steering detection plate 3, but also further understand the condition of the water flow 5 through the water level detector 7.

[0023] In this embodiment, according to the water depth of the karst spring and the water outlet pool and the formation depth of the rock, the length of the working section 1 is set to be 1 - 40m, and the length of the fixed section 2 is set to be 1 - 500m. Preferably, the length of the working section 1 is 5 - 40m, and the length of the fixed section 2 is 50 - 450m.

[0024] Preferably, the signal transmitter 8 is disposed within the working section 1.
