Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fire fighting equipment, especially relates to a relay water tank of fire-fighting high-pressure water mist system. BACKGROUND

[0002] The high-pressure water mist fire extinguishing system occupies an important position in the field of fire protection and industrial safety due to its high efficiency and environmental protection. However, the long continuous operation time, high working pressure and small nozzle aperture of the system require strict water quality for fire extinguishing. According to the Technical Code for Water Mist Fire Extinguishing System GB 50898-2013, the water used in the system must meet strict detection standards.

[0003] In practical applications, the water used for fire extinguishing in the water mist system is filtered by a filter and stored in a relay water tank for use. However, the microorganisms and algae spores that may be carried in the fire water will rapidly reproduce and enlarge the impurity particles when the system is not operated for a long time. At the same time, impurities may be produced in the pipeline due to rust, which can easily block the nozzle, cause the system to malfunction, or make the water droplet atomization diameter insufficient, thereby affecting the fire extinguishing effect and even causing secondary water pollution.

[0004] To solve this problem, some high-pressure water mist systems currently have a circulating filtration system in the relay water tank. This system can effectively remove impurities and particles in the water to ensure the cleanliness of the water source, thereby prolonging the service life of the equipment and reducing maintenance costs. However, the water quality detection equipment, such as the turbidity detector, that is matched with the circulating filtration system is mostly arranged on the inner wall of the water tank. For a fire protection system that is not operated for a long time, the water in the water tank is in a static state, and the impurities will gradually settle, making it difficult for the water quality detection equipment to accurately determine the content of impurities in the water. Once the pipeline is opened, the settled impurities will be carried away by the water flow, which can easily cause the nozzle to be blocked. SUMMARY

DETAILED DESCRIPTION

[0021] Clearly and completely describe the technical scheme of the utility model in combination with the drawings in the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] In the description of the utility model, it should be explained that the orientation or position relation indicated by the terms "intermediate", "upper", "lower", "left", "right", "inner", "outer" and the like is the orientation or position relation shown based on the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as the limitation on the utility model.

[0023] As shown in Figure 1 The specific scheme of the embodiment is as shown in Fig. 4, which comprises a relay water tank of a fire-fighting high-pressure water mist system, a platform frame 2 on which the relay water tank 1 is installed, a water injection pipe 3 arranged at the top end of the relay water tank 1, a drain pipe 4 arranged at the bottom of the relay water tank 1, a first electric control valve 5 arranged on the drain pipe 4, a water supply pipe 6 and a circulating pipe 7 arranged on the drain pipe 4 and above the first electric control valve 5, second electric control valves 8 arranged on the water supply pipe 6 and the circulating pipe 7, a mounting plate 9 arranged at the top of the relay water tank 1, and a turbidity detector 11 arranged at the bottom of the mounting plate 9 and extending into the drain pipe 4, wherein the turbidity detector 11 is flush with the positions of the water supply pipe 6 and the circulating pipe 7.

[0024] As shown in Figure 5 In the embodiment, the water injection pipe 3 is connected with a large fire-fighting water tank, the water supply pipe 6 is directly connected with each spray head of the high-pressure water mist system, and the circulating pipe 7 is connected with a reverse osmosis precision filter, and the other end of the reverse osmosis precision filter extends into the relay water tank 1 through a pipeline from the top end of the relay water tank 1, so as to achieve the purpose of circulating filtration. It should be noted that a circulating pump is further arranged on the circulating pipe 7 to provide power required for the circulating filtration, and the circulating pump is regularly operated to regularly filter the relay water tank 1.

[0025] As shown in Figures 1-2 When the circulating pipe 7 starts to circulate and filter, the water at the drain pipe 4 is in a flowing state, so that the turbidity detector 11 inside the drain pipe 4 can more accurately detect the turbidity of the water. If the turbidity still exceeds the critical value after multiple filtration and purification, the first electromagnetic valve can be controlled to be opened, so that the water in the relay water tank 1 is drained, and then new water is refilled, so as to avoid that the spray heads of the water mist system are blocked by impurities when the water is used later.

[0026] As shown in Figure 2As shown, the bottom of the relay water tank 1 is conical, and the drain pipe 4 is located at the lowest point of the bottom of the relay water tank 1. This design helps to more effectively remove the sediment and water accumulated at the bottom of the water tank, ensuring clean water quality. The inner wall of the junction between the drain pipe 4 and the relay water tank 1 is arc-shaped, reducing water flow resistance and improving drainage efficiency.

[0027] In this embodiment, a mounting port adapted to the mounting plate 9 is provided at the top of the relay water tank 1. Correspondingly, the mounting plate 9 is a convex circular plate. During installation, the mounting plate 9 can be directly buckled at the mounting port. This design makes the installation of the turbidity detector 11 and other equipment more stable, and facilitates maintenance and replacement.

[0028] In this embodiment, a screw thread is provided at the bottom end of the inner wall of the hollow rod 10, and a docking column connected with the screw thread of the hollow rod 10 is provided at the top end of the turbidity detector 11. This installation method is not only stable, but also facilitates the adjustment of the position of the turbidity detector 11, ensuring that it can accurately measure water quality.

[0029] The turbidity detector 11 in this embodiment selects a commercially available turbidity detector, such as the MIK-DC2000 online turbidity detector 11. The sensor part of the turbidity detector 11 is used as the turbidity detector of the present application, and the host computer analysis part is arranged on the mounting plate 9. The wires between the two can pass through the hollow rod 10.

[0030] It should be noted that in this embodiment, the inner diameter of the drain pipe 4 is greater than the diameter of the turbidity detector 11, which ensures that the turbidity detector 11 can fully contact the water flow and also reduces the degree of obstruction to the water flow. The turbidity detector 11 is located on the axis of the drain pipe 4, thereby more accurately measuring water quality.

[0031] The top of the mounting plate 9 is provided with a control panel 12, which controls the turbidity detector 11, the first electric control valve 5 and the second electric control valve 8. This allows the operator to conveniently control the operation of the relay water tank 1 assembly, including the switching of the electric control valves and the monitoring of the turbidity detector 11, etc., thereby improving the operational convenience of the system.

[0032] The platform frame 2 includes a bottom ring plate frame and a side wall ring. The bottom ring plate frame is arranged at the bottom of the relay water tank 1, and the side wall ring is welded around the side wall of the relay water tank 1. The side wall ring is connected to the bottom ring plate frame through a plurality of connecting columns. The bottom of the bottom ring plate frame is provided with a plurality of support columns. This design not only provides stable support, but also facilitates the installation and fixation of the relay water tank 1. At the same time, the arrangement of multiple support columns further enhances the stability and load-bearing capacity of the platform.

[0033] Working principle of the above embodiment:

[0034] When the system needs to be replenished with water, the water in the large fire water tank flows into the relay water tank 1 through the water injection pipe 3. The relay water tank 1 serves as a temporary water storage device to ensure that the system has sufficient water at any time.

[0035] In order to keep the water clean, the circulating pump on the circulating pipe 7 is started periodically to pump water out from the bottom of the relay water tank 1 and filter it through the reverse osmosis precision filter. The filtered water is then re-injected into the top of the relay water tank 1 through the pipe, achieving the purpose of circulating filtration.

[0036] During the process of circulating filtration, the turbidity detector 11 monitors the turbidity of the water in the drain pipe 4 in real time. Since the water in the drain pipe 4 is in a flowing state when the circulating pipe 7 starts to work, the turbidity detector 11 can more accurately detect the turbidity of the water.

[0037] If the turbidity detector 11 detects that the turbidity of the water exceeds the preset critical value, the control panel 12 will send a signal to control the first electric control valve 5 to open. At this time, the water in the relay water tank 1 will be discharged through the drain pipe 4 until the water tank is empty.

[0038] After the water is discharged, the operator can close the first electric control valve 5 through the control panel 12 and fill the relay water tank 1 with new water through the water injection pipe 3.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
