Wherein, the fire pool 1 is used for providing fire-fighting water; specifically, as shown in fig. 2, a water level signaling device 14 is disposed in the fire water pool 1, and the water level signaling device 14 sets three sensing water levels for sensing whether the water level in the fire water pool reaches a maximum threshold water level 15, a minimum threshold water level 16 and a normal working water level 17, where the normal working water level 17 is between the maximum threshold water level 15 and the minimum threshold water level 16. In addition, the bottom of the fire pool 1 is provided with a water outlet pipe 12, the water outlet pipe 12 is provided with a water outlet valve 13, and the water outlet valve 13 is used for controlling the water outlet of the fire pool 1 so as to be convenient for maintenance. In addition, a water pump is provided in the fire pool 1 so that water in the fire pool 1 is supplied to the fire fighting system through the water pump.
As shown in fig. 3, the differential pressure type water supply system 2 includes a mountain drainage ditch 21 and a differential pressure type water supply unit, the mountain drainage ditch 21 is located above the fire pool 1, and the mountain drainage ditch is an existing slope cut drainage ditch of the mountain, a mountain natural gully, and the like. The mountain drainage ditch 21 is used for collecting mountain catchment, and a preset height difference is formed between the mountain drainage ditch 21 and the fire pool 1; a differential pressure type water supply unit for supplying water in the mountain drainage ditch 21 to the fire pool 1 using a differential pressure; specifically, the differential pressure type water supply unit comprises a side slope rapid trough 22, a water storage sedimentation tank 23, a water supply water pipe 24 and a water storage tank water supply on-off valve 25, wherein the side slope rapid trough 22 is used for supplying water in the mountain drainage ditch 21 to the water storage sedimentation tank 23, the water storage sedimentation tank 23 is positioned between the mountain drainage ditch 21 and the fire water tank 1, namely, the mountain drainage ditch 21 is positioned above the water storage sedimentation tank 23 (with a height difference), and the water storage sedimentation tank 23 is positioned above the fire water tank 1 (with a height difference); the water storage sedimentation tank 23 is communicated with the fire pool 1 through a water supply and delivery pipe 24. The water supply water pipe 24 is provided with a reservoir water supply opening and closing valve 25 for controlling the opening and closing of the water supply water pipe 24; when the water level in the fire pool 1 is lower than the normal working water level 17, controlling the opening and closing valve 25 of the water supply of the reservoir to be opened; and when the water level in the fire pool 1 reaches the maximum threshold water level 15, controlling the water supply start-stop valve 25 of the reservoir to be closed.
As shown in fig. 4, the pump water supply system 3 includes a water well 31 and a pump water supply unit, and the water well 31 is located below the fire pond 1. Wherein, the water well 31 stores the standby water of the fire-fighting water; a pump type water supply unit for supplying water in the well 31 to the fire pool 1 by means of pumping pressure; specifically, the pump type water supply unit includes a submersible pump 32 and a water supply pipe 33; a submersible pump 32 is installed in the well 31 for delivering water in the well 31 into the fire service water pool 1 through a water supply pipe 33 for fire service water supply.
in addition, as shown in fig. 2, an overflow pipe 11 is further installed on the fire pool 1, specifically, an overflow port corresponding to the highest threshold water level 15 on the fire pool 1 is communicated to the water well 31 through the overflow pipe 11, so that water recycling is realized, and waste of water resources is avoided.
at ordinary times, mountain catchment flows to side slope rapid trough 22 through mountain escape canal 21, flows through retaining sedimentation tank 23 and stores, and the top of retaining sedimentation tank 23 has the overflow mouth, and unnecessary water flows out retaining sedimentation tank 23 through the overflow mouth and discharges and flow back to mountain escape canal through the back flow. When the water level in the fire pool 1 is lower than the normal working water level 17, the water supply opening and closing valve 25 of the impounding reservoir is automatically opened, the impounding sedimentation pool 23 automatically supplies water to the fire pool 1, and when the water level in the fire pool 1 reaches the highest threshold water level 15, the water supply opening and closing valve 25 of the impounding reservoir is automatically closed, so that the water supply process is finished. A water flow sensor is arranged in the water supply delivery pipe 24 and used for measuring the water flow in the water supply delivery pipe 24; when the water flow measured by the water flow sensor is zero and the water level in the fire pool 1 is lower than the lowest threshold water level 16, the submersible pump 32 is started; that is, when there is no available reservoir in the reservoir sedimentation tank 23 and the water level in the fire pool 1 is continuously decreased, the submersible pump 32 is automatically activated to pump water from the water well 31 through the water supply pipe 33 to supply water into the fire pool 1 when the water level is decreased to the minimum threshold water level 16. When the water level in the fire pool 1 reaches the normal working water level 17, the submersible pump 32 is automatically closed by induction, water is stored in the subsequent water storage sedimentation pool 23, water is continuously supplied to the fire pool 1 until the water level reaches the highest threshold water level 15, and the water supply start-stop valve 25 of the water storage pool is closed by induction; to this end, the water supply process is completed.
In a specific application, the mountain drainage ditch 21 and the slope rapid trough 22 are basically existing, and only a water storage sedimentation tank 23, a corresponding water supply delivery pipe 24 and a corresponding water storage tank water supply on-off valve 25 need to be additionally arranged at the upper elevation of the fire pool 1. The volume of the water storage sedimentation tank 23 is not less than that of the fire pool 1, and a water supply and delivery pipe valve, a submersible pump and a water level signal device are automatically induced, so that the intelligent and efficient operation is realized.
Example two:
The tunnel fire-fighting water supply double-supply system of the embodiment is different from the first embodiment in that:
as shown in fig. 5, the differential pressure water supply unit further includes a spare water pipe 26 for communicating the water storage sedimentation tank with the fire pool; the standby water pipe is provided with a standby control valve 27, and the standby control valve is used for controlling the opening and closing of the standby water pipe 26. Specifically, the communication position of the standby water pipe 26 and the storage sedimentation tank is lower than the communication position of the water supply water pipe and the storage sedimentation tank, so that when the water supply on-off valve of the reservoir on the water supply water pipe is opened, water above the communication position of the water supply water pipe and the storage sedimentation tank in the storage sedimentation tank can only be supplied to the fire pool, water below the communication position of the water supply water pipe and the storage sedimentation tank in the storage sedimentation tank is used as standby water, and when the standby control valve 27 is opened, the standby water in the storage sedimentation tank can be supplied to the fire pool through the standby water pipe 26. Wherein, the opening of the standby control valve 27 should satisfy the following conditions: the water flow measured by a water flow sensor in the water-supply water conveying pipe and the water-supply water conveying pipe in the water well is zero, and the water level in the fire-fighting water tank is lower than the lowest threshold water level; at this time, the standby control valve 27 is opened so that the standby water in the impoundment and sedimentation tank is supplied to the fire pool through the standby water pipe 26 in order to cope with an emergency.
Other structures can refer to the first embodiment.
The foregoing has outlined rather broadly the preferred embodiments and principles of the present invention and it will be appreciated that those skilled in the art may devise variations of the present invention that are within the spirit and scope of the appended claims.
