[0019] As described above, the utility model has the following beneficial effects:

[0020] 1. This application can use a camera to detect the water level of the fire high-level water tank in real time, so that when a fire occurs in the tunnel, there is sufficient water in the water tank to extinguish the fire and ensure the safe operation of the tunnel. In addition, when the water tank is storing water, dust is easy to fall into the surface of the water body, and the dust is easy to adhere to the surface of the measuring ruler after the water body drops. At this time, the reading of the measuring ruler is manually read through the camera. Because the scale of the measuring ruler is attached by dust, it is difficult to read. Through the counterweight block, wiper and lifting assembly designed in this application, when the measuring ruler body needs to be cleaned, the motor is started, the motor drives the counterweight block to rise, and the wiper moves with the counterweight block, thereby realizing the cleaning of the scale body. The observer can use the camera to clearly observe the reading of the measuring ruler body. After cleaning, the lifting assembly releases the counterweight block, and the counterweight block returns to the initial position.

[0021] 2. In the present application, fluorescent parts and transparent parts are provided. When the high-level water pool drops to a lower water level, the bottom has a dark field of vision due to insufficient light exposure. The fluorescent parts emit light in a dark environment to illuminate the current scale in the groove of the measuring ruler body, making it easy for humans to understand the current water level through a camera, thereby reasonably arranging the replenishment of water in the high-level water pool.

[0030] See also Figure 1-3 The utility model provides a device for detecting the liquid level information of a high-level water pool for fire fighting in a highway tunnel, comprising a floating member 2, a measuring ruler body 1, a counterweight block 3, a wiping member 4, a lifting assembly and a camera 8;

[0031] A groove is provided on the front side of the measuring ruler body 1, and a scale is provided at the bottom of the groove. The groove is slidably connected to a counterweight 3, and a side of the counterweight 3 facing the scale is connected to a wiper 4. In this embodiment, the counterweight 3 can be a stainless steel block with a plastic material coated on the surface;

[0032] In the initial state, the counterweight block 3 is located at the bottom of the measuring ruler body 1; the counterweight block 3 is lifted by a lifting assembly disposed at the top of the measuring ruler body 1, and the floating member 2 is surrounded and sleeved on the measuring ruler body 1;

[0033] The camera 8 is fixedly installed on the top of the high-level water tank. Specifically, a hole is drilled on the side wall of the top of the high-level water tank by a drilling machine, and then the camera is installed on the side wall of the top of the high-level water tank using a camera mounting frame and expansion bolts. The camera 8 is used to monitor the current position of the floating member 2 on the measuring ruler body 1. In this embodiment, the camera 8 can perform real-time monitoring and transmit the image to the computer display screen through a wireless signal, and remote monitoring can be achieved manually through the computer display screen. In this application, a camera is used to detect the water level of the fire high-level water tank in real time, so that when a fire occurs in the tunnel, there is sufficient water in the water tank to extinguish the fire and ensure the safe operation of the tunnel. Compared with the electronic probe detection method, the present application uses the floating member 2, the measuring ruler body 1 and the camera 8 to reduce the probability that the electronic probe needs to sink into the water during long-term use, and the electronic probe is damaged after water ingress.

[0034] In this embodiment, the lifting assembly includes a pull rope 7, a motor 6 and a rotating seat 5; the top of the measuring ruler body 1 is fixedly connected to the first mounting plate 10, the motor 6 is fixedly mounted on the first mounting plate 10, the rotating seat 5 is fixedly mounted on the first mounting plate 10, the output shaft of the motor 6 is rotatably mounted on the rotating seat 5, one end of the pull rope 7 is fixedly connected to the output shaft of the motor 6, and the other end is fixedly connected to the counterweight 3 after passing through the first mounting plate 10. In this embodiment, a control room connected to the signal of the motor 6 is also provided, the control room controls the action of the motor, and the motor can rotate forward or reverse. The control room can be implemented by a single chip microcomputer or a PLC control system in the prior art, which will not be repeated here. In this embodiment, when the counterweight 3 and the wiper 4 are lifted up and down in the groove on the front side of the measuring ruler body 1, the floating member 2 is provided with a perforation for the counterweight 3 and the wiper 4 to pass through. In this embodiment, when the pool is storing water, dust is easy to fall into the surface of the water body, and the dust is easy to adhere to the surface of the measuring ruler after the water drops. At this time, the reading of the measuring ruler is read manually through the camera. Since the scale of the measuring ruler is attached with dust, it is difficult to read. By designing the counterweight block 3, the wiper 4 and the lifting assembly, when the measuring ruler body 1 needs to be cleaned, the motor is started, the motor drives the counterweight block to rise, and the wiper 4 moves with the counterweight block 3, so as to achieve the cleaning of the scale body 1, and the observer can use the camera 8 to clearly observe the reading of the measuring ruler body. After cleaning, the lifting assembly releases the counterweight block 3, and the counterweight block 3 returns to the initial position.

[0037] In the present embodiment, the elastic member is a spring 9, and the elastic force of the spring 9 causes the wiping member 4 to abut against the bottom of the groove, and the gravity of the counterweight 3 is greater than the friction force generated when the wiping member 4 abuts against the bottom of the groove. In the present embodiment, the elastic force of the spring 9 causes the wiping member 4 to abut against the bottom of the groove. When the wiping member 4 is subjected to an upward pulling force, the bottom of the groove can be wiped and cleaned better, so that the scale reading at the bottom of the groove can be clearer, which is convenient for manual reading through a camera.

The hard connector 402 is a whole hard plate, which can be made of hard plastic. The hard connector 402 acts on the sponge 401. With such a design, a better cleaning effect can be achieved when cleaning.

[0041] In this embodiment, the floating member 2 is provided with a blind hole 201 with an open top, and a fluorescent member is embedded in the blind hole 201. In this embodiment, four blind holes 201 are provided, and the openings at the tops of the blind holes 201 are sealed and connected by a transparent member. In this embodiment, the transparent member is glass.

[0042] By providing fluorescent parts and transparent parts, when the high-level water pool drops to a lower water level, the bottom has a dark field of vision due to insufficient light exposure.
