Description

Building rainwater collection fire cistern

Technical field:

The utility model relates to a fire-fighting water pool, in particular to a fire-fighting water pool for building rainwater collection.

Background technique:

The building fire pool is a facility for storing and supplying fire-fighting water. When other measures cannot guarantee the water supply, it is necessary to set up a fire-fighting pool to ensure fire-fighting water. The fire-fighting pool plays a very important role in the fire-fighting process. However, since the water demand of building pools is usually large, and the water quality in fire pools often deteriorates due to standing still for a long time, water conservation has become a troubled issue.

Utility model content:

The purpose of this utility model is to overcome the phenomenon of large water demand and waste of water resources in the existing fire-fighting pools, and provide a rainwater-collecting fire-fighting pool for buildings that can collect rainwater and snow water, is suitable for different environments, and saves water resources.

Above-mentioned purpose realizes by following technical scheme:

A fire-fighting pool for collecting rainwater for buildings, which consists of: a water collection tank and a fire-fighting pool. The outlet pipe at the lower right end of the water-collecting tank is connected to the fire-fighting pool through a water pump. The upper end of the box body has an upper cover, the upper cover is arc-shaped, and a plurality of water inlet holes are evenly distributed on the upper cover, and a layer of heat insulation layer is installed on the outside of the box body. There is a heating cavity in the box, and the heating wire is covered in the heating cavity. The first filter layer, the second filter layer and the third filter layer are respectively arranged in the box from top to bottom, and the bottom left of the box is A drain pipe is installed at the end, a drain valve is installed on the drain pipe, and an outlet valve is installed on the outlet pipe.

The fire-fighting pool for collecting rainwater for the building has two temperature-measuring probes distributed up and down inside the box, and the two temperature-measuring probes are respectively electrically connected to the temperature controller.

The fire-fighting pool for collecting rainwater for buildings is equipped with liquid level gauges at the upper and lower ends of the fire-fighting pool.

The fire pool for collecting rainwater for buildings, the first filter layer is steel wire mesh, the second filter layer is polypropylene fiber, and the third filter layer is compressed activated carbon.

Beneficial effect:

1. The working principle of this utility model is: when it rains, the rainwater flows into the box through the water inlet hole on the upper cover, filters out sundries such as leaves through the first filter layer, and then finely filters through the second filter layer , and finally go through the third filter layer to remove the peculiar smell, and store it at the bottom of the tank. When the lower liquid level gauge in the fire pool leaks out, it will alarm, control the water outlet valve to open, and the water in the water collection tank will enter the fire pool through the outlet pipe. Stop water inflow when the water level in the fire pool reaches the upper liquid level gauge;

When it snows in winter, because the winter weather is cold, the temperature measuring probe detects the temperature inside the water collection tank and transmits the temperature to the thermostat, which controls the heating wire to heat, so that the temperature inside the water collection tank is controlled at 10- 20 degrees, when the snow falls on the upper cover, due to the heating of the heating wire, the temperature of the upper cover is high, and the snow melts thereupon, and flows into the box through the water inlet hole for storage.

The utility model adopts a water collecting box, so that rainwater and snowwater can be collected, which is convenient to use and can save water resources.

The upper cover of the utility model adopts a circular arc shape, which can increase the contact area between the upper cover and rainwater and snow, and facilitates collection and inflow.

The utility model is equipped with a liquid level meter, which can monitor the water level in the fire-fighting pool at any time, so that the water in the fire-fighting pool is kept sufficient.

The utility model has a simple structure, can be used in different environments, and is convenient to use.

The utility model is provided with a drainage pipe, and the water in the water collecting tank can be discharged conveniently after being left for a long time to deteriorate.

The utility model fully automatically adds water and controls temperature, does not need manpower to operate, and is safe to use.
