Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and in particular to an indoor pipe network used for indoor and outdoor fire hydrant systems and an installation method thereof. Background Art

[0002] Article 6.1.6 of the current "Technical Specifications for Fire Hydrant Water Supply and Fire Hydrant Systems" GB50974-2014 stipulates that when a high-pressure or temporary high-pressure fire water supply system is used outdoors, it should be used in conjunction with the indoor fire hydrant system.

[0003] According to the specification, when a high-pressure or temporary high-pressure fire water supply system is used outdoors, and the pressure of the indoor and outdoor fire water supply systems is similar, the specification recommends the use of a combined system of indoor and outdoor fire hydrant systems. There are currently two common practices for temporary high-pressure fire combined systems. One is a shared water pump and shared pipe network system (such as the attached Figure 1 The other is a shared water pump and separate pipe network system (such as attached Figure 2 ).

[0004] When a system with shared water pumps and shared pipe networks is used, the indoor fire hydrant system of each unit is separately connected from the shared fire-fighting pipe network. Regardless of whether the shared fire-fighting pipe network is laid in an underground garage or in the outdoor covering, the indoor fire hydrant system of each unit must form a ring. When a system with shared water pumps and separate pipe networks is used, the shared fire-fighting pipe network is divided into indoor fire hydrant systems and outdoor fire hydrant systems after coming out of the pump room. This method requires more pipes and has higher costs than a system with shared water pumps and shared pipe networks. Summary of the invention

[0005] The present invention is an improvement on the existing shared water pump and shared pipe network system, and aims to solve the problems of the existing shared water pump, separate pipe network system and the existing shared water pump and shared pipe network system requiring a large number of pipes and high cost.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an improved version of an indoor and outdoor fire hydrant system sharing an indoor pipe network, comprising the following steps: Laying out the indoor and outdoor fire-fighting pipe network based on the design drawings, and fixing the indoor and outdoor fire-fighting pipe network; Connecting the water pump adapter to the outdoor fire hydrant to the indoor and outdoor fire fighting pipe network to form a fire fighting pipe network; Sensors are installed on the fire-fighting pipe network, and control software for the fire-fighting pipe network is designed and debugged.

[0007] The specific method of installing sensors on the fire pipe network, designing the fire pipe network control software, and debugging the fire pipe network is as follows: Obtain a sensor and install it on the fire-fighting pipe network, wherein the sensor collects water pressure data in the fire-fighting pipe network in real time; Design the fire pipe network control software, and debug the fire pipe network based on the water pressure data.

[0008] Wherein, the connection end between the indoor and outdoor fire-fighting pipe network and the outdoor fire hydrant is equipped with a check valve.

[0009] Among them, the distance between the outdoor fire hydrant and the water pump connector is 15-40 meters.

[0010] In the second aspect, the present invention also provides an indoor pipe network shared by an indoor and outdoor fire hydrant system, which is applied to the installation method of the indoor pipe network shared by an indoor and outdoor fire hydrant system as described in the first aspect above, including an indoor and outdoor fire-fighting shared pipe network, a first water pump coupler, a second water pump coupler, a third water pump coupler, a first outdoor fire hydrant, a second outdoor fire hydrant, a third outdoor fire hydrant, a fourth outdoor fire hydrant and a fire water tank, and the indoor and outdoor fire-fighting shared pipe network respectively connects the first water pump coupler, the second water pump coupler, the third water pump coupler, the first outdoor fire hydrant, the second outdoor fire hydrant, the third outdoor fire hydrant, the fourth outdoor fire hydrant and the fire water tank.

[0011] The present invention discloses a method for installing an indoor pipe network for an indoor and outdoor fire hydrant system. The method comprises the following steps: laying out an indoor and outdoor fire fighting pipe network based on a design drawing, and fixing the indoor and outdoor fire fighting pipe network; connecting a water pump connector to an outdoor fire hydrant to form a fire fighting pipe network; installing a sensor on the fire fighting pipe network, designing the fire fighting pipe network control software, and debugging the fire fighting pipe network. The method arranges a set of indoor and outdoor fire hydrant system pipe networks in an underground space, and protects the water pump connector on another ring pipe network by an outdoor fire hydrant arranged on a local ring pipe network. Both ends of the two ring pipe networks are provided with a check valve, which reduces the number of indoor and outdoor fire hydrant pipe networks to the greatest extent, reduces the project cost, and solves the problem that the existing shared water pump, separate pipe network system, and the existing shared water pump, shared pipe network system are more than the improved shared water pump, and shared pipe network system, and the problem that the number of pipes required is large and the cost is high.

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] See also Figure 3 to Figure 4 In a first aspect, the present invention provides a method for installing an indoor pipe network for an indoor and outdoor fire hydrant system, comprising the following steps: S1: laying out the indoor and outdoor fire fighting pipe network 1 based on the design drawings, and fixing the indoor and outdoor fire fighting pipe network 1; S2 connects the water pump connector and the outdoor fire hydrant to the indoor and outdoor fire fighting pipe network 1 to form a fire fighting pipe network; S3 installs sensors on the fire-fighting pipe network, designs the fire-fighting pipe network control software, and debugs the fire-fighting pipe network.

[0021] Specific method: S31 obtains a sensor and installs it on the fire pipe network, wherein the sensor collects water pressure data in the fire pipe network in real time; In an embodiment of the present invention, the sensor includes a strain gauge water pressure sensor. When water pressure acts on an elastic element (such as a diaphragm) of the strain gauge water pressure sensor, the elastic element is deformed, and the strain gauge attached to its surface is also deformed, resulting in a change in the resistance value of the strain gauge. By measuring the change in the resistance value of the strain gauge and the correspondence between the resistance value and the water pressure calibrated in advance, the current water pressure value can be calculated. For example, in a calibrated strain gauge water pressure sensor, when the resistance value changes by 1Ω, the corresponding water pressure change is 0.1MPa. By measuring the change in the resistance value, the water pressure value can be accurately obtained.

[0022] S32 designs the fire pipe network control software, and debugs the fire pipe network based on the water pressure data and the air pressure data.

[0023] In the embodiment of the present invention, when debugging the fire-fighting pipe network, after the water reaches the working pressure, the fire hydrant at the most unfavorable point of the system is selected for testing. The water pump connector and the fire pump are pressurized to observe the discharge pressure of the fire hydrant, which should meet the design requirements. During the test, the water flow rate, pressure and other data of the fire hydrant are recorded and compared with the design value. If any problems are found, they are promptly checked and adjusted.
