Description

Technical Field

[0001] This utility model relates to the field of fire water circulation technology, specifically a fire water low-pressure, low-frequency circulation device. Background Technology

[0002] In fire protection engineering, fire water tanks are often needed to store water so that the water in the fire water tank can be used to extinguish fires in a timely manner. Fire water tanks are artificial water storage facilities for fixed or mobile fire pumps to draw water. Fire water tanks should be set up when the municipal water supply network or the inlet pipe cannot meet the indoor and outdoor fire water supply design flow; when there is only one fire water supply or only one inlet pipe, and the outdoor fire hydrant design flow is greater than 20L / s or the building height is greater than 50m; or when the municipal fire water supply design flow is less than the building's indoor and outdoor fire water supply design flow.

[0003] However, the water in the existing fire water tanks is stagnant, and after being left for a long time, the water in the fire water tanks will deteriorate. In severe cases, algae and duckweed will grow and be accompanied by a strong odor, making the water in the fire water tanks unusable for fire fighting operations. Therefore, corresponding improvements are needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-pressure, low-frequency fire water circulation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-pressure, low-frequency circulation device for fire-fighting water, comprising a low-pressure circulation pump, an inlet pipe connected to the bottom side of the low-pressure circulation pump, an outlet pipe connected to the top side of the low-pressure circulation pump, a circulation pipe connected to one end of the outlet pipe, and an injection pipe connected to one end of the side surface of the circulation pipe, the bottom of the low-pressure circulation pump being installed against the inner wall of the bottom of the fire-fighting water tank, buffer strips being fitted on both ends of the side surface of the circulation pipe, and the outer surfaces of the buffer strips being installed against the inner wall of the limiting ring, mounting posts being installed on the side surface of the limiting ring, and mounting plates being installed on one end of each mounting post, with threaded holes opened on both ends of one side of the mounting plate.

[0006] Preferably, a through hole is provided on one side of the inner wall of the fire water tank near the end of the outlet pipe, and one end of the outlet pipe passes through the through hole into one side of the inner wall of the fire water tank.

[0007] Preferably, a connecting hole is provided on one side of the inner wall of the fire water tank near one end of the water injection pipe, and one end of the water injection pipe passes through the connecting hole through one side of the inner wall of the fire water tank and extends into the interior of the fire water tank.

[0008] Preferably, two sets of fixing plates are installed on one side of the fire water tank near the outer side of the two sets of mounting plates, and fixing bolts are movably screwed into the interior of the two sets of fixing plates.

[0009] Preferably, the outer diameter of one end of the fixing bolt is adapted to the inner diameter of the threaded hole, and one end of the fixing bolt extends into the inside of the threaded hole and is movably screwed to it.

[0010] Preferably, the circulation pipe is inclined and the circulation pipe is set with the left side higher than the right side.

[0011] Preferably, the fixing plate is L-shaped, and one inner wall of the fixing plate is fitted to one side of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as a low-pressure circulating pump, inlet pipe, outlet pipe, circulation pipe, water injection pipe buffer strip, limit ring, mounting column, mounting plate, and threaded holes, the problem of stagnant water in existing fire water tanks, which leads to water deterioration after long-term storage, and in severe cases, the growth of algae and duckweed accompanied by a strong odor, can be effectively solved, rendering the water in the fire water tank unusable for firefighting operations.

[0014] Every one or two weeks, the user can start the low-pressure circulating pump. Under the operation of the low-pressure circulating pump, the fire-fighting water in the fire water tank can be injected into the outlet pipe through the inlet pipe. The fire-fighting water can then flow into the circulation pipe and finally into the injection pipe. Since the water level of the fire-fighting water is below that of the injection pipe, the fire-fighting water flows out of the end of the injection pipe in a waterfall shape and finally flows back into the fire water tank. At this time, the fire-fighting water can come into contact with the air, thereby increasing the oxygen content in the fire-fighting water. This process is repeated to form a water circulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] according to Figures 1-5 As shown, the system includes a low-pressure circulating pump 1. An inlet pipe 11 is connected to the bottom side of the low-pressure circulating pump 1, and an outlet pipe 12 is connected to the top side of the low-pressure circulating pump 1. One end of the outlet pipe 12 is connected to a circulating pipe 13, and one end of the circulating pipe 13 is connected to a water injection pipe 14. The circulating pipe 13 is inclined and is positioned with the left side higher than the right side. The bottom end of the low-pressure circulating pump 1 is installed on one side of the bottom inner wall of the fire water tank 3.

[0023] The side surface of the circulation pipe 13 is fitted with buffer strips 2 at both ends, and the outer surface of the buffer strips 2 is installed with the inner wall of the limiting ring 21. The side surface of the limiting ring 21 is fitted with mounting posts 22, and one end of the mounting posts 22 is fitted with a mounting plate 23. One side of the two sets of mounting plates 23 is installed with the left side of the fire water tank 3. Threaded holes 24 are opened on one side of the mounting plate 23 at both ends.

[0024] A through hole 31 is provided on one side of the inner wall of the fire water tank 3 near the end of the outlet pipe 12, and one end of the outlet pipe 12 passes through the through hole 31 into the inner wall of one side of the fire water tank 3. A connecting hole 32 is provided on one side of the inner wall of the fire water tank 3 near the end of the water injection pipe 14, and one end of the water injection pipe 14 passes through the connecting hole 32 into the inner wall of one side of the fire water tank 3 and extends into the interior of the fire water tank 3. Two sets of fixing plates 33 are installed on one side of the fire water tank 3 near the outer side of the two sets of mounting plates 23, and fixing bolts 34 are movably screwed into the interior of the two sets of fixing plates 33. The fixing plates 33 are L-shaped, and one side of the inner wall of the fixing plates 33 is fitted to one side of the mounting plate 23. The outer diameter of one end of the fixing bolt 34 is matched with the inner diameter of the threaded hole 24, and one end of the fixing bolt 34 extends into the interior of the threaded hole 24 and is movably screwed into it.

[0025] During use, fire-fighting water is injected into the fire water tank 3, and the water level is below the water inlet pipe 14. Every one or two weeks, the user can start the low-pressure circulation pump 1. Under the operation of the low-pressure circulation pump 1, the fire-fighting water in the fire water tank 3 can be injected into the water outlet pipe 12 through the water inlet pipe 11, so that the fire-fighting water can flow into the circulation pipe 13 and finally into the water inlet pipe 14. Since the fire-fighting water level is below the water inlet pipe 14, the fire-fighting water flows out of the end of the water inlet pipe 14 in a waterfall shape and finally flows back into the fire water tank 3. At this time, the fire-fighting water can come into contact with the air, thereby increasing the oxygen content in the fire-fighting water. This process is repeated to form a water circulation. In this process, the water in the existing fire water tank 3 is prevented from being stagnant. After long-term storage, the water in the fire water tank 3 will deteriorate, and in severe cases, algae, duckweed, etc. will grow and be accompanied by a strong odor, thus making the water in the fire water tank 3 unusable for fire-fighting operations.

[0026] During the circulation of fire-fighting water, the circulation pipe 13 inevitably vibrates. At this time, the two sets of buffer strips 2 fitted on the outer surface of the circulation pipe 13 can play a buffering role. The two sets of buffer strips 2 and the two sets of limiting rings 21 are fixed to the left side of the fire water tank 3 through the mounting column 22 and the mounting plate 23, which can limit and fix the circulation pipe 13. Furthermore, the mounting plate 23 can be fixed by screwing one end of the fixing bolt 34 into the inside of the threaded hole 24, so that the mounting plate 23 can be stably installed on the left side of the fire water tank 3. Through the above settings, the vibration of the circulation pipe 13 during the circulation of fire-fighting water can be avoided, so that the circulation pipe 13 can stably transport fire-fighting water.

[0027] Since the low-pressure circulating pump 1 in this scheme is used once every one or two weeks, the circulation device is low-frequency. Furthermore, the low-pressure circulating pump 1 itself is low-pressure, which makes the circulation device in this scheme a low-pressure, low-frequency design.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
