Detailed Description
As shown in fig. 1 to 7, a bottom support 1 is arranged on the ground, and the bottom support can be formed by pouring concrete or directly adopt square pipes or square timbers.
The bottom support is provided with a fire water tank 2, and the fire water tank is provided with a water outlet buckle 21, a water inlet 22 and a decontamination opening 23.
And a fire water tank water level detection device 3 is installed on the side wall of the fire water tank.
As shown in fig. 2, the fire water tank water level detection device comprises a lower connecting pipe 31, and the lower connecting pipe is connected with a decontamination opening 23.
The scheme is refined, and a connector 36 for connecting the lower connecting pipe and the decontamination opening is arranged between the lower connecting pipe and the decontamination opening.
A decontamination switch valve 231 is provided at the decontamination opening.
A check valve 311 is provided in the lower connecting pipe.
The lower connecting pipe is connected with an S-shaped pipe, the S-shaped pipe is connected with an upper transparent pipe 33, and scales are marked on the upper transparent pipe.
A water injection pipe 37 is also arranged between the S-shaped pipe and the one-way valve, and a water injection valve 371 is arranged on the water injection pipe.
Be equipped with fixed plate 34 on the fire water tank lateral wall, threaded connection has two fixation nut 35 on the fixed plate, fixation nut passes the flexion of S type pipe and utilizes the rubber pad with the laminating of S type pipe on the fixed plate surface to realize the fixed of S type pipe.
Scheme optimal design, be equipped with the guide rail on the fire water tank, sliding fit has fixed plate 34 on the guide rail, and adjusting nut can make the fixed plate locking fix the department on the guide rail.
Working method, when the water level measurement is carried out to needs, opens scrubbing ooff valve 231 for water in the fire water tank flows into to connector, lower connecting pipe, S type pipe, goes up the hyaline tube along the scrubbing mouth in, because the linker principle, the water level height in going up the hyaline tube is highly unanimous with the water level in the fire water tank, just can directly observe the water level in the fire water tank from the water tank outside.
The scheme is optimized, before opening the decontamination development valve, the water injection valve 371 is opened, after injecting colored water from the water injection pipe 37 to a certain height, the decontamination switch valve 231 is opened, so that the colored water is jacked to the water level by the subsequent water and is flush with the water level in the fire water tank. The operation observation is more convenient and clearer, and the cost is not increased.
In order to avoid excessive water injection of the fire water tank, the upper part of the upper transparent pipe 33 is connected to the middle part of the horizontal pipe 41, one end of the horizontal pipe is connected with a small vertical pipe 42, and the other end of the horizontal pipe is connected with a large vertical pipe 43.
Wherein the small vertical pipe is positioned in the fire water tank, and the length of the small vertical pipe is less than that of the large vertical pipe.
In operation, referring to fig. 4-7, when water is added to the fire-fighting water tank at the water inlet 22 such that the water level is higher than the water inlet of the small vertical pipe 42, the water enters the pipe from the small vertical pipe, the water level continues to rise such that the water level is higher than the horizontal pipe 41, the water flows out from the small vertical pipe along the horizontal pipe and the large vertical pipe under the influence of siphon action,
water flows from the water inlet 441 out of the water outlet 442 along the center tube 44 under the influence of a siphon action until the water level is equal to or lower than the water inlet of the small standpipe.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
