Description

Technical Field

[0001] This utility model relates to a device for preventing seawater backflow, and more particularly to a device for preventing seawater backflow based on telemetry and remote reporting for use in tide wells. Background Technology

[0002] In coastal areas, the underground stormwater drainage pipe facilities at dock storage yards are directly connected to the sea. With the changes in sea tides, seawater is prone to backflow during high tides, flowing back into the underground stormwater drainage pipe facilities. When the tide is too high, seawater may also overflow the tide wells and enter the ground of the dock storage yard, causing flooding. Goods, equipment, roads, etc. in the yard are soaked by seawater, which can easily cause corrosion and damage, affecting storage safety, increasing operational risks, and damaging the green environment. Utility Model Content

[0003] This utility model provides a device for preventing seawater backflow in a tide-proof well based on telemetry and remote reporting, in order to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: a device for preventing seawater backflow based on telemetry and remote reporting for a tide well, including a tide gauge fixed at the front edge of the wharf and a gate set on the outlet of the tide well. The lower end of the tide gauge is located below the seawater tide reference plane. The gate is driven to rise and fall by a winch. The motor of the winch is controlled by a contactor. The contactor is connected to a controller. The controller is electrically connected to a signal receiver. The signal receiver is wirelessly connected to a signal transmitter. The signal transmitter is electrically connected to the tide gauge. A normally closed contact of a manual switch is connected in series in the coil control circuit of the contactor. When the manual switch is activated, the coil control circuit is disconnected, the contactor is disconnected, and the motor of the winch is de-energized.

[0005] The winch is installed on the dock, and the winch cable is wound around two fixed pulleys set at the front and rear and connected to the gate.

[0006] The advantages and positive effects of this invention are as follows: It uses a tide gauge to obtain real-time tide level information and a wireless signal transmitter and receiver to transmit this information to the controller in real-time. The controller automatically controls the winch to close or open the gate, thereby automatically connecting or disconnecting the tide well and the stormwater drainage pipe. This ensures smooth drainage of rainwater or prevents excessively high tides from backflowing into the storage yard. It allows for remote real-time data transmission, real-time automatic control, telemetry and reporting, and automatic control without the need for manual intervention, saving time and effort. Furthermore, by setting a manual switch, the gate can be manually opened in extreme weather conditions such as heavy rain, connecting the tide well and the stormwater drainage pipe and preventing flooding caused by heavy rain. This invention has a simple structure, is easy to use, and has good timeliness, ensuring the safety of the storage yard. Attached Figure Description

[0009] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0010] Please see Figure 1 A device for preventing seawater backflow based on telemetry and remote reporting for a tide well includes a tide gauge 1 fixed at the front edge of the wharf and a gate 8 set on the outlet of the tide well. The lower end of the tide gauge 1 is located below the seawater tide reference level.

[0011] The gate 8 is raised and lowered by a winch 5. The motor of the winch 5 is controlled by a contactor, which is connected to a controller 4. The controller 4 is electrically connected to a signal receiver 3. The signal receiver 3 is wirelessly connected to a signal transmitter 2. The signal transmitter 2 is electrically connected to the tide gauge 1.

[0012] A normally closed contact of a manual switch is connected in series in the coil control circuit of the contactor. When the manual switch is activated, the coil control circuit is disconnected, the contactor is disconnected, and the motor of the winch is de-energized.

[0013] In this embodiment, the winch 5 is installed on the dock, and the steel cable 7 of the winch is connected to the gate 8 by passing through two fixed pulleys arranged at the front and rear. One pulley 6-1 is installed on the dock 10, and the other pulley 6-2 is installed on the wall of the moisture-proof well 9.

[0014] The working principle of this utility model:

[0015] The tide gauge 1 monitors the tide level and transmits the information to the controller 4 via the signal transmitter 2 and the signal receiver 3. When the tide level reaches or exceeds the critical point, the controller 4 controls the winch 5 to lower the gate 8 and close the outlet of the tide well 9 to prevent seawater from flowing back into the stormwater drainage pipe 11 due to excessively high tide. In case of extreme weather such as heavy rain, the winch 5 can be manually shut off by a manual switch, keeping the gate 8 open to prevent flooding. Conversely, when the tide level is below the critical point, the controller 4 controls the winch 5 to raise the gate 8 and open the outlet of the tide well 9, ensuring smooth connection between the tide well 9 and the stormwater drainage pipe 11, thus achieving the purpose of smooth rainwater drainage into the sea.

[0016] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
