Description

Technical Field

[0001] This utility model relates to the field of fire-fighting water supply equipment technology, specifically a fire-fighting pressure-stabilizing water supply equipment. Background Technology

[0002] A pressure-stabilizing pump is a type of fire pump used to stabilize the pressure in automatic sprinkler systems and fire hydrant water supply systems, ensuring that the system water pressure is always at the required level. Once water is dispensed from the sprinkler head or fire hydrant, it can provide the required amount and pressure of water for firefighting.

[0003] Chinese Patent Publication No. CN213897302U discloses a pressure-boosting and stabilizing water supply device for fire protection engineering. The device includes a square filter frame, a hemispherical filter, a base, a booster pump, a fixing seat, a stabilizing pump, and a tank. The booster pump is fixed to one side of the base. An inlet A is located at the upper end of the booster pump, and an inlet pipe is installed on inlet A. A hemispherical filter is installed at the other end of the inlet pipe and is fixed within the square filter frame by a fixing block. An outlet pipe is installed on the outlet A of the booster pump. A three-way connector is installed at the bottom of the tank, located on the outlet pipe. The tank is located in the middle of the base, and the upper end of the three-way connector is connected to the outlet at the bottom of the tank. The fixing seat is located on the other side of the base. This utility model water supply device can stably output water without worrying about unstable water pressure. Furthermore, the inlet is equipped with a two-layer filtration system to prevent clogging when pumping water from river water, thus avoiding disruption to firefighting and disaster relief efforts.

[0004] The aforementioned device mainly consists of a set of square filter frames installed on the water inlet pipe to filter out weeds or debris in the river water to prevent blockages during pumping. However, while the square filter frames have a simple structure and can block weeds or debris, when the fire is large and requires a long-term continuous water supply, weeds or debris will continuously adhere to the outside of the square filter frames, affecting the water supply. This necessitates manual cleaning of the weeds or debris. Furthermore, the device also includes a hemispherical filter to filter out small particulate impurities in the water. However, existing water pumps are not prone to blockage due to small particles in the water, and the water used for firefighting does not require high purity. Moreover, river water contains many small particulate impurities, and the hemispherical filter would accelerate the blockage process, thus affecting firefighting and disaster relief efforts. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fire-fighting pressure-stabilizing water supply device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting pressure-stabilizing water supply device, comprising a pressure-stabilizing water supply device body, and further comprising:

[0007] The filter assembly is installed at the inlet of the pressure-stabilizing water supply equipment to prevent debris from clogging the inlet of the equipment.

[0008] The filter assembly includes an inlet pipe, which is fixed to the inlet of the pressure-stabilizing water supply equipment. A flange is installed at the end of the inlet pipe, and a cylindrical frame is fixed to the flange with bolts. A rotating shaft is rotatably connected to the middle of the cylindrical frame with a bearing. An axial flow fan blade is fixed to the end of the rotating shaft. The outer end of the rotating shaft passes through the cylindrical frame and is fixed to both sides with fasteners. A slot is opened inside the fastener, and a movable part and a compression spring are fitted inside the slot. The movable part passes through the slot and is fixed with a scraper.

[0009] As mentioned above, the axial fan blades extend into the interior of the water inlet pipe.

[0010] As mentioned above, the outer periphery of the cylindrical frame is provided with several sets of mesh holes, and the diameter of the mesh holes is 10mm.

[0011] As described above, the compression spring is elastically supported between the slot and the movable part.

[0012] As mentioned above, the scraper is inclined and makes contact with the outer surface of the cylindrical frame by pressing.

[0013] As mentioned above, the cylindrical frame is connected to the water inlet pipe.

[0014] Compared with existing technologies, this fire-fighting pressure-stabilizing water supply equipment has the following advantages:

[0015] I. This utility model controls the water inlet pipe to pump water through the main body of the pressure-stabilized water supply equipment. At this time, larger impurities in the water flow will be filtered by the cylindrical frame. As the water flows, it will drive the axial flow fan blades to rotate. At this time, through the cooperation between the rotating shaft and the cylindrical frame, the fixed and movable parts will drive the scraper to move along the outer surface of the cylindrical frame. Therefore, the debris on the outer surface of the cylindrical frame can be pushed away to prevent the debris from covering the cylindrical frame and avoid clogging.

[0016] Second, this utility model has a mesh that filters only larger impurities by setting a mesh on the outer periphery of the column frame, so that it does not block small particles of impurities, thereby reducing the amount of impurities adhering to the outer surface of the column frame and preventing blockage of the water inlet of the pressure-stabilizing water supply equipment.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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.

[0025] like Figure 1-5 As shown, this utility model provides a fire-fighting pressure-stabilizing water supply device, including a pressure-stabilizing water supply device body 1, and further comprising:

[0026] A filter assembly is installed on the inlet of the main body 1 of the pressure-stabilized water supply equipment to prevent debris from clogging the inlet of the main body 1 of the pressure-stabilized water supply equipment.

[0027] The filter assembly includes an inlet pipe 2, which is fixed to the inlet of the main body 1 of the pressure-stabilized water supply equipment. A flange 3 is installed at the end of the inlet pipe 2. A cylindrical frame 5 is fixed to the flange 3 with bolts 4. A rotating shaft 6 is rotatably connected to the middle of the cylindrical frame 5 with a bearing. An axial flow fan blade 7 is fixed at the end of the rotating shaft 6. The outer end of the rotating shaft 6 passes through the cylindrical frame 5 and is fixed with fasteners 8 on both sides. A slot 9 is opened inside the fastener 8. A movable part 10 and a compression spring 11 are fitted inside the slot 9. The movable part 10 passes through the slot 9 and is fixed with a scraper 12.

[0028] When the main body 1 of the pressure-stabilized water supply equipment is running, water will be pumped using the inlet pipe 2. At this time, larger impurities in the water flow will be filtered by the cylindrical frame 5. As the water flows, it will drive the axial flow fan blade 7 to rotate. At this time, through the cooperation between the rotating shaft 6 and the cylindrical frame 5, the fixed part 8 will be driven to rotate together. Thus, the scraper 12 can be driven to move along the outer surface of the cylindrical frame 5 through the movable part 10. Therefore, the debris on the outer surface of the cylindrical frame 5 can be pushed away to prevent the debris from covering the cylindrical frame 5 and avoid blockage.

[0029] like Figure 3 As shown, the axial flow fan blade 7 extends into the interior of the water inlet pipe 2.

[0030] With the design of the axial fan blade 7, since the axial fan blade 7 extends into the interior of the water inlet pipe 2, the water flowing in from the water inlet pipe 2 will drive the axial fan blade 7 to rotate, making it easier to control the rotating shaft 6 to rotate synchronously.

[0031] like Figure 1 , 2 As shown, the outer periphery of the cylindrical frame 5 is provided with several sets of mesh holes, and the diameter of the mesh holes is 10mm.

[0032] The 10mm mesh openings on the outer periphery of the column frame 5 can filter out larger debris without blocking small particles, reducing the amount of impurities adhering to the outer surface of the column frame 5 and preventing blockage of the main body 1 of the pressure-stabilized water supply equipment.

[0033] like Figure 5 As shown, the compression spring 11 is elastically supported between the slot 9 and the movable part 10.

[0034] The design of the compression spring 11 enables the movable part 10 to have good elastic reset performance. Since the compression spring 11 is in a compressed state, it will apply an elastic force to the movable part 10, so that the movable part 10 can drive the scraper 12 to fit tightly against the outer surface of the column frame 5.

[0035] like Figure 1 , 3 As shown, the scraper 12 is inclined and is in contact with the outer surface of the cylindrical frame 5. The cylindrical frame 5 is connected to the water inlet pipe 2.

[0036] By using the slope set on the outer surface of the scraper 12, when the scraper 12 pushes the debris on the outer surface of the cylindrical frame 5, it will push the debris towards one end of the cylindrical frame 5, thus preventing the accumulation of debris.

[0037] Working principle:

[0038] During firefighting, water is pumped by activating the main body 1 of the pressure-stabilized water supply equipment. At this time, larger impurities in the water flow will be filtered by the cylindrical frame 5. As the water flows, it will pass through the cylindrical frame 5 and enter the interior of the water inlet pipe 2, thereby driving the axial flow fan blade 7 to rotate. At the same time, through the cooperation between the rotating shaft 6 and the cylindrical frame 5, the scraper 12 will be driven to rotate through the fixed part 8 and the movable part 10. And through the elastic force of the compression spring 11, the movable part 10 will be pushed to make the scraper 12 contact the outer surface of the cylindrical frame 5. Therefore, the scraper 12 can be used to push away the debris on the outer surface of the cylindrical frame 5, preventing the debris from covering the outer surface of the cylindrical frame 5 and causing blockage.

[0039] 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.
