Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting water testing devices, in particular to a water testing detection device for a fire hydrant system. Background Art

[0002] In the modern building fire safety system, the fire hydrant system is one of the most critical firefighting facilities, providing sufficient water sources for fire extinguishing work. Therefore, it is necessary to conduct regular water testing on the fire hydrant system. At present, the water testing of the fire hydrant system usually requires manual on-site operation, and the automation efficiency and response speed of pressure monitoring are slow. In addition, the key performance parameters of the fire hydrant such as hydrostatic pressure and water outlet pressure are checked by draining water. However, when draining water, the plug head is placed in the drain pipe. When the water pressure is high, it is easy to reverse the plug head out of the drain pipe, and water is also very easy to splash out of the drain pipe. Therefore, it needs to be manually pressed and fixed, and when the pipeline is long, two people are required to operate at the same time.

[0003] Therefore, it is necessary to provide a fire hydrant system water testing device to solve the problems in the above-mentioned background technology. Utility Model Content

[0004] In response to the above problems, the present application provides a fire hydrant system water test detection device, in which an embedded card and a mechanism thread of suitable specifications are fixed on the main body of the water test pipe, and the top block is adjusted through a card slot to be connected to the drain pipe, so as to selectively open and close the valves and water valves of the fire-fighting pipeline, first measure the static pressure of the fire hydrant system, and then adjust the water valve and the valve to measure the water outlet pressure of the fire hydrant system, and cooperate with each module connected by a pressure gauge to improve the efficiency and response speed of real-time pressure monitoring. In addition, after the top block fixes the tap head, it can effectively prevent leakage and reduce the reverse impact force of the water flow on the tap head during the detection process, and the displacement or falling off of the tap head, thereby maintaining the stability of the detection process and quickly processing the water flow discharged from the water test.

[0027] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0029] Figure 1-6 The fire hydrant system water testing detection device provided in the embodiment of the present application comprises: a water testing pipe body 1, a connecting pipe 2 is fixedly provided at one end of the water testing pipe body 1, and a plug head 5 is fixedly provided at the other end of the water testing pipe body 1, and an embedded card and a mechanism 6 are installed on the water testing pipe body 1 near the plug head 5;

[0030] Among them, the embedded card and mechanism 6 include: an annular seat 61 and a top block 64, the annular seat 61 is a hollow ring structure, an internal thread 62 is arranged inside it, the internal thread 62 is threadedly connected to the water test pipe body 1, and a coil wire 63 is rotatably arranged in the annular seat 61, a plurality of mounting grooves are opened on the annular seat 61, a top block 64 is movably arranged in the mounting groove, the top block 64 is meshed with the coil wire 63, the coil wire 63 is meshed with the bevel teeth 65 rotatably arranged in the annular seat 61, the bevel teeth 65 are fixed to the worm wheel 66, and the worm wheel 66 is meshed with the worm 67 rotatably arranged in the annular seat 61.

[0031] It should be noted that a drainage pipe should be provided at the corresponding position of the fire hydrant system. The inner diameter of the drainage pipe should be larger than the outer diameter of the annular seat 61, which is conducive to placing the annular seat 61 into the drainage pipe and fixing the annular seat 61 to the inner wall of the drainage pipe by utilizing the displacement of the top block 64.

[0032] Based on the above scheme, the connecting pipe 2 is first connected to the fire-fighting pipeline, and the embedded card and mechanism 6 of appropriate specifications are selected and threadedly fixed on the water test pipe body 1. The operator places the annular seat 61 into the drainage pipe and adjusts the worm 67 to rotate. The worm gear 66 drives the bevel gear 65 to rotate. After the bevel gear 65 drives the coil 63 to rotate, the top block 64 is clamped in the drainage pipe, and then the water valve 4 on the water test pipe body 1 is adjusted. The static pressure of the fire hydrant system is first measured, and then the water valve 4 on the water test pipe body 1 is adjusted to measure the water outlet pressure of the fire hydrant system, and the water outlet pressure data of the fire hydrant system is recorded. After the top block 64 fixes the plug head 5, the reverse impact force of the water flow on the plug head 5 during the water test detection process can be reduced, and the displacement or detachment of the plug head 5 and the drainage pipe can be reduced, thereby maintaining the stability of the detection process, which is conducive to the rapid processing of the water flow discharged from the water test and reducing the waste of water resources.

[0033] It should be explained that the rotation of the coiled wire 63 is regulated by the rotation of the worm 67 . Since the worm wheel 66 and the worm 67 have good self-locking properties, after the worm 67 stops rotating, the coiled wire 63 does not rotate relatively, which is convenient for limiting the top block 64 .

[0034] In addition, the annular seat 61 is threadedly connected to the water test pipe body 1, so that the embedded card and mechanism 6 of appropriate specifications can be selected according to the inner diameter of the drainage pipe. The embedded card and mechanism 6 can be placed in the drainage pipe, which is beneficial for embedded cards and mechanisms 6 of various specifications to fix the bolt head 5, thereby improving the universality of the water test detection device.

[0035] In one possible implementation, a pressure gauge 3 is installed on the water testing pipe body 1 near the connecting pipe 2. The pressure gauge 3 has a built-in 4G / 5G communication module. The pressure gauge 3 can detect the static water pressure and water outlet pressure of the fire hydrant system.

[0036] Based on the above solution, the pressure gauge 3 is equipped with a 4G / 5G communication module for recording water flow pressure. Figure 2 As shown, the 4G / 5G communication module transmits data to the remote monitoring module, and the remote monitoring module is integrated with a data processing module and an early warning module.

[0037] On the basis of the above scheme, according to the built-in embedded 4G / 5G communication module of the pressure gauge 3, the 4G / 5G communication module can transmit the data collected by the pressure gauge to the remote monitoring module in real time. The remote monitoring module stores, processes and analyzes the received pressure data through the data processing module, and generates corresponding status information and alarm signals. The early warning module monitors the processed data according to the preset threshold or algorithm. When the pressure data is monitored to be abnormal or exceeds the set range, the early warning signal is automatically triggered. The early warning signal can be notified via SMS, email, APP push, etc., to ensure timely response and processing of abnormal pressure conditions and timely feedback to the testers, thereby improving the efficiency and response speed of pressure monitoring.

[0038] In a possible implementation, the connecting pipe 2 is connected to a fire-fighting pipeline, and a valve is correspondingly provided on the fire-fighting pipeline for controlling the water flow in the fire-fighting pipeline to enter the water test pipe body 1.

[0039] Optionally, one end of the connecting pipe 2 is provided with a threaded structure, which is used for a relatively sealed connection with the fire-fighting pipeline. The other end of the connecting pipe 2 may be provided with a longer hose, which is conducive to discharging the water flowing out during the water test into drainage pipes at different positions to reduce the waste of water resources. In addition, one end of the hose is fixed to the water test pipe body 1, so that the water flow can enter the water test pipe body 1 along the hose and be discharged from the plug head 5.

[0040] In a possible implementation, a water valve 4 is installed on the water testing pipe body 1 close to one side of the connecting pipe 2 .

[0041] Based on the above scheme, during the water test, the valve of the fire-fighting pipeline is opened, and the water valve 4 on the water test pipe body 1 is closed, and the static pressure of the fire hydrant system is measured using the pressure gauge 3. Then, the water valve 4 on the water test pipe body 1 is opened, the valve of the fire-fighting pipeline is adjusted, and the water outlet pressure of the fire hydrant system is measured using the pressure gauge 3.

[0042] In a possible implementation, the annular seat 61 has a first outer diameter, the bolt head 5 has a second outer diameter, and the first outer diameter is greater than the second outer diameter.

[0043] On the basis of the above scheme, the outer diameter of the plug head 5 is smaller than the outer diameter of the annular seat 61, which is conducive to placing the plug head 5 into the drainage pipe. The water flow discharged by the water test can be processed along the drainage pipe, reducing the waste of water resources.

[0044] In one possible implementation, a soft pad is fixed on the top block 64 away from the axis of the annular seat 61. After the soft pad contacts the drain pipe, on the one hand, it can increase the friction between the two and stabilize the fixation between the two; on the other hand, it can prevent the risk of damaging the drain pipe when the hard material is subjected to force.

[0045] See also Figure 4 In one possible implementation, a slot 671 is provided at one end of the worm 67 where the contact surface with the annular seat 61 coincides. The operator can adjust the position of the top block 64 in the installation slot by cooperating with the corresponding bolt and the slot 671. Taking the square slot as an example, the corresponding square bolt is selected to adjust the position of the top block 64 clockwise or counterclockwise, and the annular seat 61 is located as a whole in the drain pipe. The top block 64 can fix the bolt head 5 in the drain pipe to prevent the bolt head 5 from shifting or falling off from the drain pipe after being subjected to the reverse impact force of the water flow during the detection of the water pressure, thereby maintaining the stability of the water test detection process and enabling the water test device to be operated by one person, thereby increasing work efficiency.

[0046] In one possible implementation, a protective plate is fixed on the annular seat 61 away from the bolt head 5, and the protective plate has a third outer diameter, and the third outer diameter is larger than the first outer diameter, so that the protective plate can close the entrance of the drain pipe and prevent water from splashing out of the drain pipe.

[0047] Working principle:

[0048] After connecting the connecting pipe 2 to the fire-fighting pipeline, select the embedded card and mechanism 6 of appropriate specifications and thread them on the water test pipe body 1 so that the protective plate blocks the drain pipe. The operator adjusts the top block 64 to be connected to the drain pipe through the cooperation of the screw and the card slot 671, then opens the valve of the fire-fighting pipeline and closes the water valve 4 on the water test pipe body 1. First, measure the static pressure of the fire hydrant system, then open the water valve 4 on the water test pipe body 1, adjust the valve of the fire-fighting pipeline, and measure the water outlet pressure of the fire hydrant system. The static pressure and water outlet pressure are transmitted in real time to the remote monitoring module according to the 4G / 5G communication module in the pressure gauge 3. The remote monitoring module stores, processes and analyzes the received pressure data through the data processing module, and generates corresponding status information and alarm signals. When the pressure data is detected to be abnormal or exceeds the set range, the early warning module automatically triggers the early warning signal, and the early warning signal can be notified and fed back to the tester through SMS, email, APP push, etc.

[0049] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, various changes and modifications made without departing from the concept of the present application should be deemed to belong to the protection scope of the present application.
