[0002] Both the simple sprinkler fire extinguishing system and the standard sprinkler fire extinguishing system are a kind of fire sprinkler equipment. Their main function is to spray water mist to extinguish fires. The main differences between the simple sprinkler fire extinguishing system and the standard sprinkler fire extinguishing system lie in the application scope and occasions. Compared with the standard sprinkler fire extinguishing system, the simple sprinkler fire extinguishing system is applicable to some simple fire prevention and explosion-proof sprinkler systems, such as various places without automatic sprinkler fire extinguishing systems like the "nine small" places, so as to quickly extinguish the fire source in case of a fire, and its structure is simpler.

[0003] However, the water pipe network currently adopted by the simple sprinkler fire extinguishing system is the water pipe network of the standard fire extinguishing system, including pipe network, signal valve, sprinkler pump, water flow indicator, wet alarm valve, gate valve, etc. The cost is very high, and it is necessary to install each component, and the on-site construction is very troublesome. Moreover, various state information of the water pipe network cannot be monitored, so it needs to be solved urgently. Content of the Utility Model

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an integrated prefabricated pipe network to solve the problem that the simple sprinkler fire extinguishing system has no special water pipe network.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] An integrated prefabricated pipe network, which includes: a pipeline and a monitoring group, a collector and a solenoid valve that are sequentially connected along the signal transmission direction;

[0007] The input end of the pipeline is connected to the municipal water supply,

[0008] The monitoring group is arranged at the inner end of the pipeline and is used for monitoring various data in the pipeline. The collector is located in the middle section outside the pipeline and is used for collecting the data monitored by the monitoring group. The solenoid valve is located at the input end of the pipeline and is used for controlling the opening and closing of the pipeline;

[0009] The monitoring group includes a sensor and a water flow indicator connected in parallel, and the sensor is used for monitoring environmental data;

[0011] As a further scheme of the utility model: the sensor includes a pressure sensor and a temperature sensor. The pressure sensor is used for monitoring the static and dynamic water pressures in the pipe, and the temperature sensor is used for monitoring the water temperature in the pipe.

[0012] As a further solution of the utility model: the alarm range of the pressure sensor is 0.05 - 1.6 Mpa.

[0013] As a further solution of the utility model: the alarm range of the temperature sensor is 40 - 145 °C.

[0014] As a further solution of the utility model: the alarm range of the water flow indicator is greater than or equal to 20 L / min.

[0015] As a further solution of the utility model: the integrated prefabricated pipe network is connected to an external controller, and the external controller is used to receive the data collected by the collector and send a control opening and closing signal to the solenoid valve.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model provides an integrated prefabricated pipe network to solve the problem that the simple sprinkler fire extinguishing system has no special water pipe network. Moreover, the structure of the integrated prefabricated pipe network is simple. On-site, only according to the size of the site and the needs of the place, the prefabricated pipes can be connected by clamps and assembled, and then connected to the external controller through a network cable, so as to complete the installation of the water pipe network of the simple sprinkler fire extinguishing system, which is simple and convenient.

[0018] 2. The monitoring group of the utility model can monitor various environmental data inside the pipeline.

The temperature sensor can monitor the water temperature inside the pipeline, and the water flow indicator is used to monitor the water flow state. By monitoring a variety of data inside the pipeline through the detection group, it is possible to monitor the external environment and various data inside the pipeline, judge whether a fire has occurred, and more quickly conduct the water pipe network of the simple sprinkler fire extinguishing system to provide water source for the sprinkler heads at the end of the pipe network, so as to facilitate timely fire prevention and extinguishing, and be safer.

[0019] 3. The integrated prefabricated pipe network in the utility model can cascade multiple prefabricated pipes according to the size of the site to meet the needs of various sites, and has a wide application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 - Figure 2 , in the embodiments of the present invention, an integrated prefabricated pipe network, the integrated prefabricated pipe network 1 includes: a pipe 2 and a monitoring group, a collector 3 and a solenoid valve 4 that are sequentially connected along the signal transmission direction; the input end of the pipe 2 is connected to the municipal water supply 5, the monitoring group is arranged at the inner end of the pipe 2 for monitoring various data 3 in the pipe 2, the collector 3 is located in the middle section outside the pipe 2 for collecting the data monitored by the monitoring group and sending an alarm signal to the external control 9, and the solenoid valve 4 is located at the input end of the pipe 2 for controlling the opening and closing of the pipe 2; using the integrated prefabricated pipe network 1 as the special water pipe network of the simple sprinkler fire extinguishing system, so that when the water pipe network of the simple sprinkler fire extinguishing system is constructed on site, only the prefabricated pipe sections need to be connected by clamps according to the site size and site requirements, and the installation of the water pipe network can be completed, which is more simple and convenient. Compared with the water pipe network of the standard sprinkler fire extinguishing system, the economic cost is also greatly reduced, which is more suitable for the application in small and micro businesses.

[0026] The monitoring group includes a sensor and a water flow indicator 6 connected in parallel. The sensor is used to monitor environmental data. The sensor includes a pressure sensor 7 and a temperature sensor 8. The pressure sensor 7 is used to monitor the static and dynamic water pressures in the pipe. The temperature sensor 8 is used to monitor the water temperature in the pipe. The water flow indicator 6 is used to monitor the water flow state. The monitoring group can monitor the changes of various data in the pipeline 2 in real time. The sensor and the water flow indicator 6 are connected to the collector 3 through the same bus. The integrated prefabricated pipe network 1 is connected to the external controller 9. The external controller 9 is used to receive the data collected by the collector 3 and send it to the solenoid valve. 4 sends out a control opening and closing signal. When a device in the monitoring group reaches the set alarm value, it can send an alarm signal to the collector 3. After receiving the alarm signal, the collector 3 transmits the alarm signal to the external controller 9. After receiving the alarm signal, the external controller 9 sends a control instruction to the solenoid valve 4, and finally enables the external controller 9 to control the solenoid valve 4 to open so that the pipeline 2 is conductive. After the pipeline 2 is conductive, water can flow from the municipal water supply 5 from the input end of the pipeline 2 into the integrated prefabricated pipe network 1, providing a water source for the simple sprinkler fire extinguishing system, so that the simple sprinkler fire extinguishing system can perform fire prevention and fire extinguishing operations.

[0027] The pipeline 2 adopts DN25 galvanized steel pipe, which can be prefabricated in three lengths of 5 meters, 10 meters and 15 meters according to demand. The pipelines 2 are cascaded and fixed by DN25 clamps, and the solenoid valve 5 cooperates with the pipeline 2 to adopt a DN25 solenoid valve; the solenoid valve 4, pressure sensor 7, temperature sensor 8 and water flow indicator 6 are all installed inside the pipeline 2, and holes are opened at the installation positions of the pipeline 2 corresponding to the solenoid valve 4, pressure sensor 7, temperature sensor 8 and water flow indicator 6, so that the lines of each device can be connected to the outside, and a sealing ring is provided at the opening for sealing to prevent water from seeping out, and the collector 3 is fixed to the outside of the pipeline 2 by a clamp (it should be noted that the fixation of the solenoid valve 4, pressure sensor 7, temperature sensor 8 and water flow indicator 6 in the pipeline 2 and the setting of the sealing ring are all existing technologies, and the specific setting distance of the solenoid valve 4, pressure sensor 7, temperature sensor 8 and water flow indicator 6 can be changed according to demand, so it will not be repeated).

[0028] The pressure sensor 7 can monitor the static and dynamic water pressures inside the pipeline. When a fire occurs, after the external sprinkler heads connected to the output end of the pipe network are opened, the original full-water state of the pipeline 2 changes, causing the static and dynamic water pressures inside the pipeline 2 to decrease; the temperature sensor 8 can monitor the water temperature inside the pipeline. When a fire occurs, the temperature of the external environment rises, and the water temperature inside the pipeline 2 rises under the action of heat transfer; the water flow indicator 6 is used to monitor the water flow state. When the external sprinkler heads are opened, the water flow in the pipeline 2 will flow; through the monitoring of various data inside the pipeline by the detection group, it is possible to detect various data inside the external environment and the pipeline 2, determine whether a fire has occurred, and more quickly conduct the water pipe network of the simple sprinkler fire extinguishing system, provide water source for the external sprinkler heads at the end of the pipe network, so as to conduct fire prevention and extinguishing in a timely manner and be safer.

[0029] Among them, the alarm range of the pressure sensor 7 is 0.05 - 1.6 Mpa. In this embodiment, the alarm value of the pressure sensor 7 is set to 0.07 Mpa; the alarm range of the temperature sensor 8 is 40 - 145 °C. In this embodiment, the alarm value of the temperature sensor 8 is set to 50 °C, and the alarm range of the water flow indicator 6 is greater than or equal to 20 L / min. In this embodiment, the alarm value of the water flow indicator 6 is set to 37.5 L / min. In other embodiments, the alarm values of the devices in the detection group can be adjusted according to requirements. When the collector 3 collects the real-time data value detected by a certain device among the pressure sensor 7, the temperature sensor 8 or the water flow indicator 6 that exceeds the alarm value, the collector 3 sends an alarm message to the external controller 9, causing the external controller 9 to send a control opening and closing signal to the solenoid valve 4 to open the solenoid valve 4, so that the municipal water supply 5 can provide water source for the simple sprinkler fire extinguishing system to conduct fire extinguishing operations.
