Description

Technical Field

[0001] This utility model relates to the field of monitoring devices, and in particular to a building fire water supply monitoring device. Background Technology

[0002] The building fire water system monitoring system mainly involves installing wireless pressure transmitters and wireless level transmitters at key locations within the fire water system. This enables monitoring of the pressure at the sprinkler terminals, water levels in high-level water tanks, water levels in low-level water pools, and pressure at unfavorable points in the fire water system. All monitoring data is transmitted to the fire water system monitoring platform via NB-IoT communication. This platform provides alarms for abnormal pressure and level data, and performs online monitoring and comprehensive analysis of the entire fire water system's operation. It can quickly locate fault points within the fire water system and push alarm information to relevant management personnel via SMS, WeChat, etc., allowing for timely handling of faults or alarms, reducing fire safety hazards, and ensuring the fire water system functions effectively during a fire.

[0003] In existing technologies, to ensure that fire water tanks can supply water to the system during a building fire, monitoring devices are often installed on the fire water tanks to monitor the water level and ensure sufficient water supply. Currently, this is generally achieved by installing a level gauge on the fire water tank. The level gauge is fixed to the installation port of the fire water tank using its own mounting flange and bolts and nuts. This installation method requires auxiliary tools and mounting components, making the installation of the monitoring device cumbersome. The level gauge is one of the important devices for monitoring the water level in the fire water tank; if it malfunctions, abnormal water levels may not be detected in time, affecting the normal operation of the fire protection system. Therefore, prolonged operation or improper handling of the level gauge may cause damage or wear, affecting its normal operation. Furthermore, when replacement is needed, timely disassembly is inconvenient, further complicating the installation and use of the level gauge. Utility Model Content

[0004] The main purpose of this utility model is to provide a building fire water supply monitoring device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A building fire water supply monitoring device includes a fire water tank. A level gauge is mounted on the top surface of the fire water tank, and a measuring rod is mounted on the bottom end of the level gauge. A float is mounted on the outside of the measuring rod, and a limiting ring is also mounted on the bottom outer end of the measuring rod. The fire water tank is fixedly connected to the top of the mounting opening on the top surface of the fire water tank via an installation mechanism. The installation mechanism includes a connecting plate, a fixing rod, a compression spring, an L-shaped movable plate, and a locking block. The connecting plate is fitted onto the outside of the bottom end of the level gauge through a through hole on its top surface. Fixing rods are fixedly connected to the inner sides of the top surface of the connecting plate, and compression springs are fitted onto the outside of the fixing rods. The L-shaped movable plate is movably connected to the fixing rods through connecting holes on its side wall and is fixedly connected to the inner end of the compression spring. The locking block is fixedly connected to the bottom of the inner side wall of the L-shaped movable plate.

[0007] Preferably, the top surface of the fire water tank is fixedly equipped with an installation port, and the top surface of the installation port is provided with a set of left-right symmetrical positioning grooves.

[0008] Preferably, a set of symmetrical slots are provided on the outer wall of the mounting port.

[0009] Preferably, the top surface of the connecting plate has a through hole and is fixedly installed on the outside of the bottom end of the level gauge in a fitted manner through the through hole, and positioning rods are fixedly installed on the bottom surface of the connecting plate on the left and right sides of the through hole, respectively, and the positioning rods are inserted into the positioning groove.

[0010] Preferably, the top surface of the connecting plate is provided with a set of symmetrical transverse movable openings, and the inner front and rear side walls of the transverse movable openings are respectively provided with sliding grooves. The fixing rod is fixedly installed inside the transverse movable openings, and a compression spring is fitted on the rod body of the fixing rod. The outer end of the compression spring is fixedly installed on the inner end wall of the transverse movable opening.

[0011] Preferably, the vertical sidewall of the L-shaped movable plate has a connecting hole, and the L-shaped movable plate is movably installed together with the fixed rod through the connecting hole and passes through the horizontal movable opening. The inner end of the compression spring is fixedly installed on the outer sidewall of the vertical part of the L-shaped movable plate, and sliders are fixedly installed on the front and rear sides of the vertical part of the L-shaped movable plate and movably installed in the slide groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the installation mechanism involves manually pulling the handles on the left and right sides of the top surface of the connecting plate in opposite directions until it can no longer be pulled. Maintaining this pulling force, the positioning rod on the bottom surface is inserted into the positioning groove. Releasing the pulling force on the handles allows the L-shaped movable plate to move inward along the fixed rod through the connecting hole under the elastic restoring force of the compression spring until the locking block is inserted into the locking groove. This achieves the purpose of quickly installing the level gauge on the fire water tank. Pulling the handles again in the opposite direction causes the locking block to move out of the locking groove, allowing the level gauge to be disassembled from the fire water tank for repair or replacement. This facilitates the installation and removal of the level gauge on the fire water tank, enabling timely replacement of the level gauge in case of damage or malfunction, ensuring effective monitoring of the fire water tank and guaranteeing the normal operation of the fire protection system.

The data can be transmitted remotely to the control room to realize the automatic detection, control and recording of liquid level.

[0020] The fire water tank 1 is fixedly connected to the top of the mounting port 7 on the top surface of the fire water tank 1 by the mounting mechanism 6. The mounting mechanism 6 includes a connecting plate 10, a fixing rod 15, a compression spring 16, an L-shaped movable plate 17 and a locking block 20. The connecting plate 10 is sleeved on the outside of the bottom end of the liquid level gauge 2 through the through hole 11 on the top surface. The fixing rod 15 is fixedly connected to both sides of the top surface of the connecting plate 10. The compression spring 16 is sleeved on the outside of the fixing rod 15.

[0021] like Figure 2 As shown, the top surface of the fire water tank 1 is fixedly equipped with an installation port 7, and the top surface of the installation port 7 is provided with a set of left and right symmetrical positioning grooves 8. The positioning grooves 8 on the top surface of the installation port 7 are used to cooperate with the positioning rod 12, so that the level gauge 2 can be positioned and installed on the fire water tank 1.

[0022] like Figure 2 As shown, a set of symmetrical slots 9 are provided on the outer wall of the mounting port 7. The slots 9 provided on the mounting port 7 are used to cooperate with the use of the card block 20. After the card block 20 enters the slot 9, the installation operation of the level gauge 2 is completed.

[0023] like Figure 3 As shown, the top surface of the connecting plate 10 has a through hole 11, and the plate is fixedly installed on the bottom of the level gauge 2 in a sleeve manner through the through hole 11. The bottom surface of the connecting plate 10 is fixedly installed on the left and right sides of the through hole 11, and the positioning rods 12 are inserted into the groove of the positioning groove 8. The connecting plate 10 can be fixedly installed on the bottom of the level gauge 2 through the through hole 11, and the connection between the measuring rod 3 and the level gauge 2 can be ensured. The positioning rod 12 can be inserted into the positioning groove 8 to position the level gauge 2 at the top of the installation port 7, and the measuring rod 3 and the float 4 on the measuring rod 3 can enter the fire water tank 1 and cooperate with the level gauge 2 to monitor the water level in the fire water tank 1.

[0024] like Figure 3As shown, the top surface of the connecting plate 10 is also provided with a set of symmetrical horizontal movable openings 13, and the front and rear side walls of the horizontal movable openings 13 are respectively provided with sliding grooves 14. The fixing rod 15 is fixedly installed inside the horizontal movable openings 13, and a compression spring 16 is fitted on the rod body of the fixing rod 15. The outer end of the compression spring 16 is fixedly installed on the inner end wall of the horizontal movable opening 13. The horizontal movable openings 13 on the connecting plate 10 are used to cooperate with the horizontal part of the L-shaped movable plate 17 to achieve movement, and the sliding grooves 14 are used to cooperate with the slider 19 to achieve sliding. When the compression spring 16 outside the fixing rod 15 inside the horizontal movable opening 13 is squeezed, it will retract and when the squeezing force is lost, it will elastically recover.

[0025] like Figure 3 As shown, a connecting hole 18 is provided on the vertical side wall of the L-shaped movable plate 17, and the L-shaped movable plate 17 is movably installed together with the fixed rod 15 through the connecting hole 18 and passes through the horizontal movable opening 13. The inner end of the compression spring 16 is fixedly installed on the outer side wall of the vertical part of the L-shaped movable plate 17, and sliders 19 are fixedly installed on the front and rear sides of the vertical part of the L-shaped movable plate 17 and movably installed in the slide groove 14. A locking block 20 corresponding to the locking groove 9 is fixedly installed on the inner side wall of the horizontal part of the L-shaped movable plate 17, and a handle 21 is fixedly installed on the top surface of the vertical part of the L-shaped movable plate 17. Pulling the connecting plate 10 in the opposite direction The handles 21 on both sides of the top surface drive the L-shaped movable plate 17, which moves along the fixed rod 15 through the connecting hole 18 and forces the compression spring 16 to retract until it can no longer pull the handle 21. After the pulling force on the handle 21 is maintained and the positioning rod 12 is inserted into the positioning groove 8, the pulling force on the handle 21 is released, and the L-shaped movable plate 17 is pushed by the elastic recovery of the compression spring 16, so that the locking block 20 is inserted into the locking groove 9. The level gauge 2 can then be quickly installed on the top surface of the fire water tank 1. When disassembling, simply pull the handles 21 to both sides until it can no longer be pulled, and then remove the level gauge 2 upwards.

[0026] It should be noted that this utility model is a building fire water supply monitoring device. When the level gauge 2 is installed on the fire water tank 1 to monitor the water level in the fire water tank 1, the handles 21 located on the left and right sides of the top surface of the connecting plate 10 are manually pulled in opposite directions. The handles 21 will drive the vertical part of the L-shaped movable plate 17 to move outward through the connecting hole 18 on the side wall and along the fixed rod 15 installed in the horizontal movable opening 13 on the top surface of the connecting plate 10. During the movement, the L-shaped movable plate 17 moves outward through the connecting hole 18 on the side wall and along the horizontal movable opening 13 on the top surface of the connecting plate 10. The sliders 19 installed on the front and rear sides of the vertical part of the plate 17 will slide within the grooves 14 opened on the front and rear side walls of the horizontal movable opening 13, forcing the compression spring 16 mounted on the fixed rod 15 to retract until the handle 21 can no longer be pulled. Maintaining the pulling force on the handle 21, the liquid level gauge 2 is lifted through the handle 21, and the measuring rod 3 at the bottom of the liquid level gauge 2 is inserted into the fire water tank 1 through the installation port 7. The measuring rod 3 and the float 4 on the measuring rod 3 enter the fire water tank 1 and work with the liquid level gauge 2 to achieve the measurement of the liquid level. The water level in the fire water tank 1 is monitored. Simultaneously, the positioning rod 12 installed on the bottom surface of the connecting plate 10 is inserted into the positioning groove 8 on the top surface of the installation port 7 to achieve positioning installation. Then, the pull handle 21 is released, and the compression spring 16 will elastically extend and push the L-shaped movable plate 17 inwards until the locking block 20 installed on the inner wall of the horizontal part of the L-shaped movable plate 17 is inserted into the locking grooves 9 on both sides of the outer wall of the installation port 7. This allows the level gauge 2 to be quickly installed on the fire water tank 1 for use. The purpose is to ensure that when the level gauge 2 malfunctions or is damaged and needs to be repaired or replaced, the handles 21 on both sides of the top surface of the connecting plate 10 are pulled in the opposite direction again. This causes the L-shaped movable plate 17 to move the locking block 20 out of the slot 9, allowing the level gauge 2 to be removed from the installation port 7 for repair or replacement. This facilitates the installation and removal of the level gauge 2 on the fire water tank 1, enabling timely replacement of the level gauge 2 in case of damage or malfunction, thus ensuring effective monitoring of the fire water tank 1 and guaranteeing the normal operation of the fire protection system.
