[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example:

[0028] like Figures 1 to 7 As shown, this utility model provides a fire pipeline pressure testing device, including two sets of pipeline bodies 1 and a tee pipe 2. The two sets of pipeline bodies 1 are located on both sides of the tee pipe 2 and are respectively connected to both sides of the tee pipe 2. A control valve 3 is also installed in the longitudinal part of the tee pipe 2. A connecting pipe 101 is also provided at the end of the control valve 3 away from the tee pipe 2. A pressure gauge 4 is also installed on the connecting pipe 101. An installation platform 102 is also provided on one side of the connecting pipe 101. A control module 103, a data acquisition device 104, and a battery 105 are respectively installed in the installation platform 102. The control module 103 is electrically connected to the data acquisition device 104 and the battery 105. The data acquisition device 104 is also connected to the pressure gauge 4. A transmission module 106 is also provided at the top of the installation platform 102 and is electrically connected to the control module 103. The two sets of pipeline bodies 1 are connected in a T-shape through the tee pipe 2 to form a stable pipeline structure. The longitudinal cavity of the tee pipe 2 provides installation space for the control valve 3, which runs through it. The opening and closing state of the valve core determines the water flow direction. When open, the valve core is fully open, and the water flows smoothly through the tee pipe 2 and the two sets of main pipe bodies 1, ensuring the detectability of the fire pipeline detection system. When closed, the valve core blocks the water flow in the longitudinal cavity, isolating the detection area formed by the connecting pipe 101 and the connected pressure gauge 4. This facilitates the disassembly, inspection, and maintenance of the pressure gauge 4, connecting pipe 101, and other components by maintenance personnel without having to drain the entire fire pipeline system. The control module 103 can be model 6ES7-134-6GF00-0AA1. The transmission module 106 is a wireless module and can be model MD-S280G-P2.

[0029] The pressure gauge 4 is connected with the data collector 104 by wire. The pressure gauge 4 senses the pressure of the pipeline water flow and outputs a signal. The data collector 104 receives the signal and converts it into a specific form for storage. The control module 103 sends an instruction to the data collector 104 at a preset time, and the data collector 104 feeds back the processed data to the control module 103 after receiving the instruction. The control module 103 processes the data according to a predetermined algorithm to generate valid data. The control module 103 transmits the data to the transmission module 106 through an electrical circuit, and the transmission module 106 packages the data according to a fixed protocol and transmits it wirelessly. The monitoring terminal receives the wireless signal, unpacks and restores the data, and realizes the whole process of data collection and transmission; the data collector 104 can be of ADAM-6017 type.

[0030] The storage battery 105 is placed inside the installation table 102 and forms a closed circuit with the control module 103 through wire to provide stable power supply for the whole detection system. The control module 103 distributes electric energy through a circuit to ensure the operation of the pressure gauge 4 signal acquisition, data processing and wireless transmission function. This independent power supply method makes the equipment free from dependence on the power supply of the fire pipeline system and can still work continuously when the power is off or the main power supply fails, ensuring uninterrupted pressure data collection.

[0031] As shown in Figure 1 As shown in Figure 2 The two sides of the tee pipe 2 are provided with first connecting flanges 201, and the two groups of pipeline bodies 1 are provided with second connecting flanges 202 on the side close to the tee pipe 2. The two groups of second connecting flanges 202 are fixedly connected with the two groups of first connecting flanges 201 through a plurality of fixing bolts. Two groups of installation grooves 301 are respectively arranged between the two groups of first connecting flanges 201 and the two groups of second connecting flanges 202, and a first sealing ring 302 made of rubber is arranged in each installation groove 301. The first connecting flange 201 and the second connecting flange 202 are detachably connected through the fixing bolts. During installation, the two groups of flanges are aligned, and the bolts are screwed in to fix the pipeline body 1 and the tee pipe 2. During disassembly, the bolts are loosened to separate the components. This connection method makes the operation simple during maintenance and replacement of the pipeline body 1 or the tee pipe 2, and a single person can complete the operation without special tools, reducing the difficulty and time cost of maintenance. The first sealing ring 302 is arranged in the installation groove 301, and the bolts are tightened to extrude the sealing ring when the flanges are connected. The sealing ring is deformed by extrusion to fill the gap between the flanges. The sealing ring made of rubber has good elasticity and toughness, can tightly fit the surface of the flange, prevents leakage of the medium in the pipeline from the connection part, ensures the stability of the pressure of the fire pipeline system, and avoids affecting the accuracy of pressure detection and the water supply effect during fire extinguishing due to leakage.

[0032] As shown in Figures 1 to 2As shown, the vertical pipe of the tee pipe 2 and the connecting pipe 101 are internally threaded, the control valve 3 is externally threaded at both ends, the tee pipe 2 is connected to the connecting pipe 101 and the control valve 3 through threading, and the tee pipe 2, the connecting pipe 101 and the control valve 3 are further provided with a second sealing ring 401. The vertical pipe of the tee pipe 2, the internal thread of the connecting pipe 101 and the external thread of the control valve 3 are matched, the control valve 3 is screwed into the vertical pipe of the tee pipe 2 during installation, and then the connecting pipe 101 is tightened; during disassembly, the components are separated by reversing the rotation, which is simple to operate and beneficial to the independent maintenance and replacement of the tee pipe 2, the connecting pipe 101 and the control valve 3; the second sealing ring 401 is installed at the connection position of the tee pipe 2, the connecting pipe 101 and the control valve 3, and is deformed under pressure during the threading process, filling the gap between the components and preventing the medium in the pipeline from leaking from the threaded connection, ensuring stable pipeline pressure and accurate pressure gauge 4 measurement data, and ensuring normal operation of the fire pipeline system.

[0033] As shown in Figure 2 , Figure 3 , Figure 6 and Figure 7 , the connecting pipe 101 is provided with a limiting portion 501, and the limiting portion 501 and the control valve 3 are further provided with a filter 5, which includes a shell 502 and an end cover 503. The bottom of the shell 502 is detachably connected with the end cover 503, and the two opposite ends of the shell 502 and the end cover 503 are respectively in contact with the limiting portion 501 and the control valve 3. The filter 5 further includes two groups of filter elements 601. The shell 502 is a hollow structure, and the shell 502 is further provided with a support frame 602. The support frame 602 is further provided with two groups of mounting portions, and the two groups of mounting portions are respectively provided with a stainless steel filter screen 603. The two groups of filter elements 601 are clamped between the two groups of filter screens 603. One group of filter elements 601 is made of sponge fiber material, and the other group of filter elements 601 is made of glass fiber material. The shell 502 and the end cover 503 are connected by buckling, and the end cover 503 can be directly contacted with the filter elements 601 clamped between the two groups of filter screens 603 by using a standard tool during maintenance. The filter elements 601 are tightly attached to the inner wall of the shell 502 through an elastic sealing ring, forming an independent filtering unit. When replacing the filter elements 601, the overall connection of the connecting pipe 101 and the tee pipe 2 does not need to be disassembled, and the replacement of the filter elements 601 can be completed by a single person, reducing system downtime. The limiting portion 501 and the control valve 3 respectively form mechanical limiting on both ends of the filter 5, and the contact surface of the shell 502 and the end cover 503 forms an axial seal after tightening. This positioning method keeps the filter 5 stable when the medium flows, avoiding displacement caused by vibration or pressure fluctuation. After the medium enters the connecting pipe 101, it is forced to pass through the filtering area of the filter elements 601, ensuring the impurity interception efficiency. The detachable structure of the end cover 503 and the shell 502 also allows the filter screen 603 to be removed periodically for cleaning to restore the filtering performance.

[0034] The three-layer filter structure forms a hierarchical interception system in the filter 5 between the limiting part 501 and the control valve 3. When the medium flows in, the stainless steel filter screen 603 first blocks large-particle impurities such as sand and slag by virtue of the regular mesh structure; the sponge fiber filter element 601 captures rust and colloidal substances suspended in the medium by virtue of the porous adsorption characteristics; and the glass fiber filter element 601 further filters microorganisms and flocculation substances by virtue of the dense structure of micron-level fibers interwoven. The impurities are intercepted in order of particle size, ensuring that the medium entering the pressure gauge 4 meets the cleanliness standard; the clean medium enters the pressure gauge 4, avoiding direct impact of impurities on the internal sensing elements. The filter screen 603 prevents large particles from scratching the internal sensing diaphragm of the pressure gauge 4, and the sponge and glass fiber filter elements 601 reduce the risk of blockage caused by impurity accumulation. Impurities cannot adhere to the sensing surface of the pressure gauge 4, maintaining the smoothness of the pressure measurement channel, avoiding pressure fluctuation misjudgment caused by impurity interference, keeping the pressure gauge 4 always stable in measurement accuracy, and prolonging the service life of the core components.

[0035] As Figure 3 With Figure 5 shown, the installation table 102 is also provided with a warning light 801 on one side, and a buzzer 802 is also provided on the installation table 102 near the warning light 801; the installation table 102 is also provided with a control switch 901 on the other side away from the warning light 801, the control switch 901 is electrically connected with the warning light 801 and the buzzer 802, and the control switch 901 is also electrically connected with the control module 103. The warning light 801 and the buzzer 802 are installed on the side of the installation table 102, when the control module 103 detects abnormal pressure data, it sends an electrical signal to the warning light 801 and the buzzer 802 through the circuit. The warning light 801 emits light and the buzzer 802 emits sound to remind the surrounding personnel that the pipeline pressure is abnormal in two ways of light and sound, without relying on remote monitoring, so that the on-site personnel can detect and take measures in the first time; the control switch 901 is connected with the warning light 801, the buzzer 802 and the control module 103. When routine maintenance or alarm function is not needed, the circuit can be disconnected through the control switch 901 to turn off the warning light 801 and the buzzer 802, avoiding interference caused by false alarm; when the alarm function is needed, the circuit connection is restored by closing the control switch 901. Maintenance personnel can also manually test whether the warning light 801 and the buzzer 802 are working normally through the control switch 901, which is convenient for troubleshooting.

[0036] As Figure 3 With Figure 7As shown, the bottom of the mounting table 102 is also provided with a battery compartment, the replaceable storage battery 105 is arranged in the battery compartment, and the battery compartment is also provided with a battery cover 1001, the battery cover 1001 is in contact with the battery compartment, and is connected with the battery compartment through a plurality of groups of bolts. The bottom of the mounting table 102 is provided with a battery compartment, and the storage battery 105 is directly placed in the compartment. The battery cover 1001 is fixed on the battery compartment through a plurality of groups of bolts. When the storage battery 105 is replaced, the bolts are unscrewed and the battery cover 1001 is removed, the old battery can be taken out and the new battery can be placed in. The operation steps are simple, special tools are not required, the battery replacement is completed conveniently and quickly, the continuous power supply of the equipment is ensured, the battery cover 1001 is in close contact with the battery compartment, the storage battery 105 is stably arranged in the battery compartment through the fixing of the plurality of groups of bolts, and the storage battery 105 is prevented from being displaced or falling off due to vibration during equipment operation.
