Description

Technical Field

[0001] The utility model relates to the technical field of fire safety, and particularly relates to an intelligent end water testing device. Background Technique

[0002] The end water testing device is installed at the end of the automatic sprinkler fire extinguishing system pipeline or sub-pipeline to test the functions such as system startup, alarm and linkage. To test the reliability of the automatic sprinkler fire extinguishing system and to test whether the system can reliably alarm and start normally under the most unfavorable condition of opening one sprinkler, it is required to set an end water testing device at the most unfavorable water supply point of each alarm valve.

[0003] The end water testing device is not only used during acceptance, but also plays an important role in daily maintenance and inspection. By regularly testing the end water testing device, system failures can be detected in time to ensure that the system can operate normally during a fire. In the actual use process, two valves are installed on the pipeline for end detection, and the two valves are respectively located on the upper and lower sides of the pressure gauge. The valve installed on the upper side of the pressure gauge is used to protect the pressure gauge. The pressure gauge will only display the pressure data when the valve is opened, which can well cope with daily detection. However, this will result in the inability to determine whether the water pressure in the pipe meets the requirements during the period between two detections, presenting a safety risk. Content of the Utility Model

[0004] The purpose of the utility model is to provide an intelligent end water testing device to solve the above-mentioned deficiencies in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an intelligent end water testing device, comprising: a fire pipe, on which a second three-way joint, a first valve, a first three-way joint, and a second valve are sequentially arranged. The first three-way joint is communicated with a pressure gauge, the second three-way joint is communicated with a detection pipe, a sliding plug is slidably arranged in the detection pipe, a spring is arranged between the sliding plug and the inner cavity of the detection pipe, an alarm is arranged on one side of the detection pipe, a first contact switch and a second contact switch are arranged on the alarm in the vertical direction, a chute is opened on the detection pipe, a vertical rod is fixedly connected to the sliding plug, and the vertical rod is located between the first contact switch and the second contact switch after extending out of the chute.

[0006] Further, a base is fixedly connected in the detection pipe, and the bottom end of the sliding plug is inserted into the base.

[0007] Further, a bell mouth is arranged below the fire pipe.

[0008] Further, the bottom end of the fire pipe is threadedly connected with a splash-proof cover, and the outer diameter dimension of the splash-proof cover is slightly smaller than the inner diameter dimension of the bell mouth.

[0009] Further, the first three-way joint is connected to an elbow through a threaded connecting pipe, and the other end of the elbow is connected to a pressure gauge through a metal hose.

[0010] In the above technical solution, the beneficial effects of an intelligent end water testing device provided by the present utility model are as follows:

[0011] In the present utility model, a second three-way joint is provided on the fire pipe to communicate with the detection pipe. When the water pressure in the fire pipe increases, the sliding plug is squeezed, and then slides upward after overcoming the elastic force of the spring. The vertical rod squeezes the first contact switch to make the alarm energized and emit an alarm. When the water pressure in the fire pipe decreases, the sliding plug is squeezed, and then slides downward after overcoming the elastic force of the spring. The vertical rod squeezes the second contact switch to make the alarm energized and emit an alarm. Through the setting of the above device, when the water pressure in the fire pipe is too small or too large, an alarm can be issued in real time, improving the reliability of fire-fighting equipment and avoiding potential safety risks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0020] Please refer to FIGS. 1-2. An intelligent end water testing device includes: a fire pipe 1, on which a second three-way joint 13, a first valve 2, a first three-way joint 3, and a second valve 4 are sequentially arranged. The first three-way joint 3 is connected to a pressure gauge 9, and the second three-way joint 13 is connected to a detection pipe 14. A sliding plug 16 is slidably arranged in the detection pipe 14. A spring 15 is arranged between the sliding plug 16 and the inner cavity of the detection pipe 14. An alarm 12 is arranged on one side of the detection pipe 14. The alarm 12 is provided with a first contact switch 121 and a second contact switch 122 in the vertical direction. A chute 141 is formed in the detection pipe 14. A vertical rod 161 is fixedly connected to the sliding plug 16. After the vertical rod 161 extends out of the chute 141, it is located between the first contact switch 121 and the second contact switch 122.

[0021] Specifically, refer to Figure 1 and Figure 2, the fire pipe 1 is divided into a main pipe and multiple threaded connecting pipes. The bottom end of the main pipe is threadedly connected to the second tee joint 13. The lower end of the second tee joint 13 is connected to the first valve 2 through the first threaded connecting pipe. The first valve 2 is connected to the first tee joint 3 through the second connecting pipe. The lower end of the first tee joint 3 is connected to the second valve 4 through the fourth threaded connecting pipe. The lower end of the second valve 4 is threadedly connected to the fifth threaded connecting pipe. Under normal circumstances, the first valve 2 is in the closed state and the first tee joint 3 is in the open state. When regular inspection is required, the first valve 2 is opened and the first tee joint 3 is closed, and the value of the pressure gauge 9 is observed to see if it meets the standard. Then the first tee joint 3 is opened. When the water in the fire pipe 1 drains out from the outlet of the fifth threaded connecting pipe, the value of the pressure gauge 9 is observed to see if it meets the standard. The pressure of the water in the fire pipe 1 is judged whether it meets the standard through the above two data. In the present utility model, a second tee joint 13 is provided on the fire pipe 1 to communicate with the detection pipe 14. Since the first valve 2 is in the closed state, after the water pressure in the fire pipe 1 increases, it squeezes the sliding plug 16, so that the sliding plug 16 slides upward after overcoming the elastic force of the spring 15, and the vertical rod 161 squeezes the first contact switch 121 to make the alarm 12 energized to give an alarm. After the water pressure in the fire pipe 1 decreases, it squeezes the sliding plug 16, so that the sliding plug 16 slides downward after overcoming the elastic force of the spring 15, and the vertical rod 161 squeezes the second contact switch 122 to make the alarm 12 energized to give an alarm. Through the setting of the above device, when the water pressure in the fire pipe 1 is too small or too large, an alarm can be issued in real time, improving the reliability of the fire-fighting equipment and avoiding potential safety risks.

[0022] Furthermore, a base 162 is fixedly connected inside the detection pipe 14, and the bottom end of the sliding plug 16 is inserted into the base 162.

[0023] Specifically, referring to Figure 1 and Figure 2 , by setting the base 162, when the water pressure in the fire pipe 1 is too small or there is no water in the fire pipe 1, the contact force between the vertical rod 161 and the chute 141 is avoided under the elastic force of the spring 15, protecting the vertical rod 161.

[0024] Furthermore, a flared mouth 6 is provided below the fire pipe 1.

[0025] Specifically, referring to Figure 1 , by providing the flared mouth 6 below the fire pipe 1, the water discharged from the fifth threaded connecting pipe can be collected, and the state of the water discharged from the fifth threaded connecting pipe can be well observed, so as to serve as a factor for judging the fire safety index.

[0026] Furthermore, a splash-proof cover 5 is threadedly connected to the bottom end of the fire pipe 1, and the outer diameter dimension of the splash-proof cover 5 is slightly smaller than the inner diameter dimension of the flared mouth 6.

[0027] Specifically, referring toFigure 1 , the splash-proof cover 5 is externally threadedly connected to the fifth-section threaded connecting pipe. During detection, by screwing the splash-proof cover 5 upward, the splash-proof cover 5 is separated from the bell mouth 6, and the state of the water discharged from the fifth-section threaded connecting pipe can be observed. During non-detection periods, the splash-proof cover 5 is inserted into the bell mouth 6, avoiding the situation where the bell mouth 6 is blocked by garbage and dust, and reducing the later maintenance cost; during actual use, a water test joint 51 is threadedly connected to the bottom end of the fifth-section threaded connecting pipe. The flow coefficient of the water outlet of the water test joint 51 should be equal to the flow coefficient of the sprinkler with the minimum flow coefficient on the same floor or in the same fire compartment. Before testing the pressure in the pipe, the water test joint 51 is removed to discharge the sundries in the pipe, ensuring the smooth flow of water at the water outlet of the water test joint 51; a drainage pipe is connected below the bell mouth 6, and the diameter of this drainage pipe is not less than DN75.

[0028] Furthermore, the first three-way joint 3 is connected to an elbow 7 through a threaded connecting pipe, and the other end of the elbow 7 is connected to a pressure gauge 9 through a metal hose 8.

[0029] Specifically, there are certain requirements for the installation height of the pressure gauge 9. When installing the end water test device in different terrains, the installation positions of the first valve 2, the first three-way joint 3, and the second valve 4 may change. At this time, the length of the metal hose 8 needs to be changed to meet the installation height of the pressure gauge 9.

[0030] In the present utility model, there are various ways to arrange the alarm 12. For example: a corresponding wireless module can be set in the alarm 12, which is in the same wireless network environment as the terminal device. In this way, the alarm can transmit the alarm signal wirelessly to the terminal device to remind the staff that a fault has occurred; for example: directly connect to the terminal device through a data cable and transmit the alarm signal of the alarm to the terminal; regardless of which connection method is adopted between the alarm 12 and the terminal, the alarm 12 can transmit the alarm signal to the terminal, ensuring that the alarm signal is discovered and measures are taken in the first time.

[0031] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
