Description

Technical Field

[0001] This utility model relates to the field of fire water tank pressure monitoring technology, and in particular to a fire water tank pressure monitoring device. Background Technology

[0002] Monitoring the water pressure in fire water tanks is a crucial step in ensuring the normal operation of fire protection systems. By monitoring water pressure and level in real time, potential fire safety hazards can be identified and addressed promptly.

[0003] Therefore, the existing water tank pressure testing device, with publication number CN207556739U, has the following steps for testing water tank pressure using the water tank pressure testing device provided by this utility model: (1) Remove the rubber stopper and let air enter the stud. When the stud is full of air, tighten the rubber stopper; (2) Press the handle down, and the rubber sheet will bulge under pressure; (3) Place the water tank pressure testing device into the water area to be tested. The bulging rubber sheet will contract due to the water pressure. The pressure sensor senses the pressure change of the stud and displays the pressure change value on the pressure display screen. The pressure change value of the stud is the pressure value of the tested water.

[0004] However, existing devices may not be suitable for scenarios with deep water tanks. If the water tank is deep, the rubber sheet needs to be inserted deeper to accurately measure water pressure, and existing devices may not meet this requirement because the downward stroke of the handle is limited by the mechanical structure, and the design of the stud and handle may not have enough space to achieve a large downward stroke.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figures 1-4 As shown, a fire water tank pressure monitoring device includes a water tank 1 and a water pressure sensor 14. When the water pressure sensor 14 is located at the bottom of the water tank 1, it can detect the water pressure inside the water tank 1 in real time. Two mounting seats 2 are detachably installed on the inner wall of the water tank 1. The two mounting seats 2 are arranged longitudinally and installed at the top and bottom edges of the inner wall of the water tank 1, respectively. A sprocket 3 is rotatably connected to the surface of the mounting seat 2, and a chain 12 is meshed between the two sprockets 3. Figure 1 As shown, this solution can be implemented by installing a motor outside the water tank 1. The motor drives the sprocket 3 on the surface of the upper mounting base 2 to rotate, which in turn enables the chain 12 to move with the assistance of the lower sprocket 3. A bottom box 4 is rotatably connected to the bottom edge of one half of the chain 12 located on one side of the two sprockets 3. A connecting block 11 is fixedly installed on the outer wall of the bottom box 4 and fits onto the other half of the chain 12 located on the other side of the two sprockets 3. With the assistance of the connecting block 11, the bottom box 4 moves up and down inside the water tank 1 as the chain 12 moves, making it convenient for personnel to disassemble and assemble the bottom box 4 when the water tank 1 is emptied. The opening of the bottom box 4 is located on the side, and the water pressure sensor 14 is fixedly installed on the top of the inner box of the bottom box 4. During detection, the bottom box 4 is connected to the inside of the water tank 1, and the water pressure in the water tank 1 can be detected by the water pressure sensor 14 in the bottom box 4.

[0020] A cover 5 is inserted into the opening of the bottom box 4. A horizontally positioned sealing plate 13 is fixedly installed on the top edge of the cover 5. An electric telescopic rod 8 is fixedly installed on the bottom of the inner box of the bottom box 4 near the opening. The telescopic end of the electric telescopic rod 8 passes through the top of the bottom box 4 and is fixedly connected to the bottom surface of the sealing plate 13. When the electric telescopic rod 8 is fully retracted, the cover 5 seals the opening of the bottom box 4, and the corresponding sealing plate 13 fits against the top of the outer box of the bottom box 4. That is, the cover 5 and the sealing plate 13 are used to separate the bottom box 4 from the water tank 1, preventing the water pressure sensor 14 from being in the detection state for a long time and affecting the measurement accuracy. When needed, the electric telescopic rod 8 is used to push the sealing plate 13 to raise the cover 5 and open the opening of the bottom box 4.

[0021] The bottom of the inner box 4 is fitted with four corner positions, each with an upwardly retractable electric push rod 10. Several piston plates 9 are fixedly installed at the retractable ends of the electric push rods 10. The piston plates 9 are arranged in a "┌" shape and fitted onto the surface of the cylinder of the electric telescopic rod 8. The outer wall of the vertical side of the piston plate 9 is flush with the opening of the bottom box 4. A three-way valve 6 is installed at the top of the bottom box 4, and a valve 7 is installed at the bottom of the bottom box 4. One valve port of the three-way valve 6 penetrates the top of the bottom box 4, while the other two valve ports communicate with the inside and outside of the water tank 1, respectively. The two valve ports of the valve 7 penetrate the bottom of the bottom box 4 and the bottom of the water tank 1, respectively. Figure 4 and Figure 2 As shown, with the lid 5 sealing the opening of the bottom box 4, the piston plate 9 is pushed up by the extension of the electric push rod 10. Before the piston plate 9 rises, the valve 7 is opened to connect the space below the piston plate 9 with the external space of the water tank 1. Then, the valve port connected to the inside of the water tank 1 of the three-way valve 6 is opened. The piston plate 9 rises to squeeze the water in the upper space of the bottom box 4 into the water tank 1. Then, the valve port connected to the inside of the water tank 1 is closed, and the valve port connected to the outside of the water tank 1 is opened to facilitate the piston plate 9 to descend. This ensures that the water pressure sensor 14 is in a dry and water-deficient state, thereby ensuring that the water pressure sensor 14 is in a non-working state.

[0022] Working principle: When it is necessary to detect the water pressure in water tank 1, the electric telescopic rod 8 pushes the sealing plate 13 to drive the cover 5 to rise and open the bottom box 4. The bottom box 4 is connected to the inside of water tank 1, and the water pressure sensor 14 in the bottom box 4 can be used to detect the water pressure in water tank 1. After the detection is completed, the bottom box 4 is separated from water tank 1 by the cover 5 and the sealing plate 13. The valve 7 is opened to connect the space below the piston plate 9 with the external space of water tank 1. Then the three-way valve 6 is connected to the valve port inside water tank 1 and opened. The piston plate 9 rises to squeeze the water in the upper space inside the bottom box 4 into water tank 1. Then the valve port connected to the inside of water tank 1 is closed and the valve port connected to the outside of water tank 1 is opened to facilitate the piston plate 9 to descend. This ensures that the water pressure sensor 14 is in a dry and water-deficient state, thus ensuring that the water pressure sensor 14 is in a non-working state.

[0023] The wiring diagrams for the motor, three-way valve 6, electric telescopic rod 8, electric push rod 10, valve 7, and water pressure sensor 14 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts for the motor, three-way valve 6, electric telescopic rod 8, electric push rod 10, valve 7, and water pressure sensor 14 will not be explained in detail.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
