Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of monitoring equipment, and in particular relates to a splicable water level monitoring device for a tunnel fire water pool. Background Art
[0002] Highway tunnel fire water tanks are specially used to store water for tunnel firefighting. They are mainly used to provide water for firefighting, relieve water pressure, and serve as a backup water source for other structures around the tunnel. Therefore, water level monitoring of tunnel fire water tanks is related to whether the tunnel fire water tanks can provide sufficient water in the event of an accident.
[0003] Ultrasonic level meters are commonly used to monitor the water level of fire water tanks in common highway tunnels. Ultrasonic level meters use the principle of ultrasonic reflection to measure water level distance and have the characteristics of non-contact measurement. The disadvantages of ultrasonic level meters are as follows:
[0004] (1) Ultrasonic level meters are greatly affected by the environment. Temperature changes affect the speed of sound, which in turn affects measurement accuracy. In environments with large temperature fluctuations, additional equipment needs to be installed for temperature compensation. In addition, the humidity and environmental noise around the ultrasonic level meter can also cause measurement errors. The location of the tunnel fire water tank usually has large temperature and humidity changes, making the ultrasonic level meter susceptible to these changes.
[0005] (2) Ultrasonic level meters are greatly affected by the medium. Ultrasonic level meters are not suitable for measuring liquids containing a large amount of suspended particles or foam, because these substances will absorb or scatter sound waves, affecting signal transmission. Tunnel fire water tanks are only used when accidents occur, so suspended particles and other biological debris are easily present in the water.
[0006] (3) Ultrasonic level meters are easily affected by reflective surfaces. Tunnel fire water tanks are located near the tunnel. The movement of vehicles can easily cause the liquid level in the fire water tank to fluctuate. The irregular liquid surface will cause the ultrasonic level meter's reflected signal to be unstable, affecting the measurement results. In addition, if the tunnel fire water tank experiences vibration and turbulence, the ultrasonic level meter may not be able to provide stable readings. Summary of the Invention
[0007] In response to the problems existing in the above-mentioned prior art, the utility model provides a tunnel fire water pool splicing water level monitoring device. The purpose is to monitor the water levels of tunnel fire water pools of different depths in real time without the need for staff to go to the site, and to obtain water level monitoring data in real time. At the same time, it can also reduce the influence of temperature, humidity and debris in the water during the monitoring process, and ensure the accuracy of water level information acquisition.
[0008] In order to achieve the above purpose, the specific solutions of the present utility model are as follows:
[0009] The tunnel fire water tank can be spliced with water level monitoring equipment, including a splicing structure and a control mechanism. The equipment shell is installed on the top of the splicing structure. The splicing structure is composed of multiple splicing parts that are sequentially fitted and connected. A water level sensing module is installed on one side surface of each splicing part. A splicing part signal slot is provided on the top of each splicing part to connect with the water level sensing module. The control mechanism includes an equipment shell, an electric push rod, a horizontal connecting rod, a swing rod and an electromagnet. A signal slot is installed on one side of the equipment shell. The signal slot of each splicing part is connected to the slot port of the signal slot. The electric push rod is installed on the other side of the equipment shell. The push head of the electric push rod is connected to one end of the horizontal connecting rod. A rolling shaft is installed on the other end of the horizontal connecting rod. One end of the swing rod is hinged on the rolling shaft, and the electromagnet is installed on the other end of the swing rod.
[0010] Furthermore, it includes an electric push rod drive, a control chip, an NBIOT module and a power supply installed in the device shell, and a control button installed on the top of the device shell. The electric push rod is connected to the electric push rod drive, and the signal slot, the electric push rod drive, the NBIOT module, the control button and the electromagnet are respectively connected to the control chip, and the power supply provides the working voltage of the control chip.
[0011] Furthermore, it includes a terminal device, which is connected to the NBIOT module and is a mobile phone, notebook, tablet computer or computer.
[0012] Furthermore, a splicing protrusion is provided on the top of the splicing piece, and a splicing groove adapted to the splicing protrusion is respectively provided on the bottom of the splicing piece and the bottom of the device shell.
[0013] Furthermore, the signal slot is provided with a plurality of slot openings.
[0014] Advantages of the present invention
[0015] This utility model's tunnel fire water tank can be expanded through the use of splicing components to connect water level monitoring equipment, enabling it to monitor water levels in tunnel fire water tanks of varying depths.

The electric push rod 8 is mounted on the other side of the device housing 16. The push rod head of the electric push rod 8 is connected to one end of the cross-link 17, the other end of which is mounted with a rolling shaft 9. One end of the swing arm 15 is hinged to the rolling shaft 9, and the electromagnet 10 is mounted on the other end of the swing arm 15. The function of the rolling shaft 9 is to manually control the rotation of the swing arm 15 to control the electromagnet 10 to approach the surface of the fire water tank, and to use the magnetic force of the electromagnet to stabilize the control mechanism on the edge of the fire water tank 18. The slot opening 101 of the signal slot 1 is used to provide a terminal for connecting to the control chip 4. The splice signal slot 11 is used to provide a terminal for connecting the electrical signal of the splice 14. The splice signal slot 11 is connected to the signal slot 1 via an electrical wire, so that the water level sensing module 13 is connected to the control chip 4 through the splice signal slot 11 and the signal slot 1, thereby allowing the control chip 4 to obtain water level information of the splice 14.
[0026] The electric push rod 8 is connected to the electric push rod driver 5.
