Technical Field

The utility model relates to the technical field of fire pumps, in particular to an indoor fire-fighting system for a wharf.

Background

At present, fire extinguishing systems are installed at a crude oil receiving and unloading dock and an office building, accidental factors lead to false triggering of a fire hydrant box alarm button in the dock office building once, so that the indoor fire extinguishing systems are started by mistake, the pressure of fire fighting pipelines rises instantly, the pipeline design pressure is far higher than the pressure, the pipeline is more rusted and is extremely easy to burst due to the fact that the indoor fire extinguishing systems are operated for 10 years, and therefore the current pipeline is required to be remodel so as to prevent false triggering and prevent damage to the pipeline.

Disclosure of Invention

The utility model provides a wharf indoor fire-fighting system for effectively solving the problems in the background art.

The specific technical scheme is as follows;

the utility model provides an indoor fire extinguishing systems of pier, includes fire-fighting flume, fire-fighting pipeline, shower nozzle, fire-fighting water pump and controller, the controller control fire-fighting water pump is with the water in the fire-fighting flume through fire-fighting pipeline into the shower nozzle in, installs electric pressure gauge and motorised valve on the terminal branch pipe of fire-fighting pipeline, and electric pressure gauge installs the front end at terminal branch pipe, and the motorised valve is installed at terminal of terminal branch pipe, and electric pressure gauge and motorised valve all pass through the wire with the controller and are connected, pass through the water piping connection of return water with the fire-fighting flume at the terminal of terminal branch pipe.

Preferably, an electric butterfly valve is mounted on the fire-fighting pipeline.

Preferably, a one-way valve is also arranged on the same pipeline as the electric butterfly valve.

Preferably, the foremost end of the end branch is provided with a manual valve.

Preferably, a main pipeline pressure gauge is arranged on the fire-fighting pipeline.

Compared with the prior art, the utility model has the beneficial effects that: the device is additionally provided with the electric contact pressure gauge and the electric valve, so that once the water pressure of the fire control outlet pipeline exceeds the set safety value, the electric contact pressure gauge gives out a signal to control the electric valve to automatically open and release pressure, and the fire control pipeline is ensured not to be blocked to cause accidents even if the fire control pump is started by mistake. The reliability of indoor fire control is ensured, the safety of fire control in an office building is positively acted, and meanwhile, under the conditions that a fire pump is in misoperation and is started by mistake, the indoor fire control equipment and facilities can safely and stably run, and the safety of equipment and facilities is ensured.

Detailed Description

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be oriented 90 degrees or at other orientations and the spatially relative descriptors used herein interpreted accordingly.

The following detailed description of the utility model refers to the accompanying drawings and preferred embodiments. As shown in figure 1, the indoor fire extinguishing system of wharf comprises a fire water tank 1, a fire pipeline 2, a spray head 3, a fire water pump 4 and a controller 5, wherein the controller controls the fire water pump to pump water in the fire water tank into the spray head through the fire pipeline, an electric pressure gauge 7 and an electric valve 8 are arranged on a tail end branch pipeline 6 of the fire pipeline, the electric pressure gauge is arranged at the front end of the tail end branch pipeline, the electric valve is arranged at the tail end of the tail end branch pipeline, the electric pressure gauge and the electric valve are connected with the controller through wires, and the tail end of the tail end branch pipeline is connected with a water inlet pipe of the fire water tank through a water return pipeline. The mechanical safety valve is parallel to the electric valve, and the starting pressure is regulated to be slightly higher than the starting pressure of the electric valve, so that even if the electric valve fails to control, the fire pump can release the redundant pressure of the pipeline once being started by mistake, and the safe and stable operation of the fire equipment is ensured.

An electric butterfly valve 9 is arranged on the fire-fighting pipeline, the electric butterfly valve is controlled to be opened by a controller, and the electric butterfly valve is a main switch. The check valve 10 is also arranged on the same pipeline as the electric butterfly valve, so that the fire pump is damaged due to the reverse flow of water caused by the overlarge pressure in the pipeline, and the problem can be effectively solved by arranging the check valve.

The foremost end of the end branch pipe is provided with a manual valve 11. When the pressure of a certain tail end branch pipeline is too high and the electric valve is damaged, the manual butterfly valve is closed to prevent water from continuously filling water into the tail end branch pipeline, and a mechanical safety valve is arranged in parallel with the electric valve.

To facilitate the knowledge of the pressure on the main fire line, a main line pressure gauge 12 is mounted on the fire line.

The fire-fighting water tank is characterized in that the tail end pipeline is connected with the water inlet pipe of the fire-fighting water tank, the tail end of the water inlet pipe valve is arranged, the fire-fighting water tank can be directly discharged into the fire-fighting water tank, the fire-fighting water tank is also provided with a voltage gauge, the pressure in the water tank is detected, and the safety of the water tank is ensured. And a negative pressure inhibitor is arranged on the fire-fighting water tank to prevent the pressure in the water tank from being too small.

The device is provided with two fire-fighting water pumps, an empty pipeline is arranged between the two fire-fighting water pumps, when the pressure in the main pipeline is too high, the electric valve on the pipeline can be started, and the electric valve on the fire-fighting water pump is closed, so that water can flow back from the pipeline, and the key is that the fire-fighting water pump cannot be damaged.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
