Description

Technical Field

[0001] The invention relates to the technical field of fire protection, and in particular to a fire sprinkler system used in building construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations.

[0003] The existing technology has the following problems: when using a water tank to store rainwater, external impurities can enter the water tank through the opening above the water tank. In order to prevent impurities in the water tank from entering the water pipe, a baffle is usually set at the end of the water pipe to prevent impurities from entering the water pipe. When the water tank is idle for a long time, a large amount of impurities accumulate inside it. The staff needs to clean the impurities in the water tank regularly. At this time, the liquid in the water tank needs to be emptied, and the waiting time is greatly increased, which leads to low efficiency of water tank cleaning; when extinguishing the fire at the fire point, the flowing water carries the impurities in the water tank into contact with the filter plate at the end of the water pipe. A large amount of impurities block the filter plate, resulting in the inability of water to pass through the water pipe smoothly, resulting in poor fire extinguishing effect.

[0017] (1) The present invention provides a filter plate, a first screw, a second screw, a sliding plate and a scraper. A large amount of impurities in the water tank accumulate on the surface of the filter plate. The first screw rotates regularly so that the filter plate drives the impurities on the surface of the filter plate to move upward, so that the filter plate contacts the scraper under the sliding plate. Then, the second screw rotates so that the sliding plate drives the scraper to push the impurities on the surface of the filter plate to leave the water tank through the discharge trough, thereby completing the cleaning of the inside of the water tank. Due to the use of automated equipment, the staff does not need to clean the water tank.

[0018] (2) Since the first limit plate is fixedly installed on the bottom surface of the filter plate, the first hose is located between the bottom surface of the filter plate and the bottom of the inner wall of the water storage tank. When extinguishing a fire, the water flow carries impurities and contacts the filter plate. Under the action of pressure, the water flows smoothly through the filter plate and enters between the bottom surface of the filter plate and the bottom of the inner wall of the water storage tank, preventing impurities from clogging the first hose, thereby improving the fire extinguishing effect;

[0019] (3) The spiral spring sheet inside the reeling mechanism enables the second hose to be automatically reeled when not in use, saving space while ensuring that the second hose can be pulled out smoothly when in use. This design not only saves space but also avoids the problem of the hose being entangled and tangled during use;

[0020] (4) After the construction is completed, the staff can cut off the first hose as needed, so that the entire equipment can be slightly modified to meet other needs after the construction, thereby improving the overall flexibility of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0034] Reference Figure 1-7As shown, a fire sprinkler system for building construction includes a water tank 1, which is arranged on the top of the building. The water tank 1 stores liquid required for fire fighting. Since the upper surface of the water tank 1 is provided with an opening, the water tank 1 can store rainwater on rainy days. At the same time, a water inlet pipe is provided on the side of the water tank 1, and the external water flow can supplement the water flow in the water tank 1 through the water inlet pipe. A plurality of first screw rods 2 are rotatably installed on the inner wall of the water tank 1. The plurality of first screw rods 2 are symmetrically distributed about the center line of the water tank 1, and the plurality of first screw rods 2 are externally connected to a power source. , a filter plate 3 is provided inside the water storage tank 1, and the filter plate 3 is threadedly connected to a plurality of first screw rods 2. The material of the filter plate 3 is a stainless steel filter element. The advantages of the stainless steel filter element filter plate are as follows: 1. It has extremely strong corrosion resistance and can resist the erosion of various corrosive media such as acids, alkalis, salts, etc., ensuring the stability and long service life of the filtration system; 2. The stainless steel material has high strength and excellent wear resistance, so that the stainless steel filter element filter plate can still maintain a stable filtering effect when subjected to high pressure, high temperature and high-speed fluid impact, thereby extending the service life; 3. The surface of the stainless steel filter element filter plate is smooth, not easy to adhere to impurities, and easy to clean and regenerate; 4. The stainless steel filter element filter plate can be reused, reducing material waste and environmental pollution. A plurality of first screw rods 2 rotate at the same time, thereby causing the filter plate 3 to move up and down along the axial direction of the first screw rod 2. Since external impurities can enter the water storage tank 1 through the opening above the water storage tank 1, the filter plate 3 blocks the impurities. The bottom surface of the filter plate 3 corresponding to the first screw rod 2 is fixedly installed with a first limit plate 4, and the side of the water storage tank 1 is fixedly installed with a first hose 5, and the first hose 5 is connected to the storage tank 1. The water tank 1 is connected, and the first hose 5 corresponds to the first limit plate 4. The first limit plate 4 prevents the filter plate 3 and impurities from blocking the first hose 5, thereby ensuring the normal operation of the first hose 5. The end of the first hose 5 away from the water tank 1 is connected to the winding mechanism 6. A second hose 610 is provided inside the winding mechanism 6. One end of the second hose 610 is connected to the spraying device 7. The staff sprays the fire point through the handheld spraying device 7. At the same time, the winding mechanism 6 can be contracted and extended through the second hose 610, which is convenient for the staff to move the spraying device 7.

[0035] like Figure 3 As shown, slide rails 8 are fixedly installed on both sides of the inner wall of the water tank 1, and second screw rods 9 are rotatably installed inside the two slide rails 8. A sliding plate 10 is provided inside the water tank 1, and the sliding plate 10 is threadedly connected to the two second screw rods 9. A scraper 11 corresponding to the filter plate 3 is fixedly installed on the bottom surface of the sliding plate 10. When the filter plate 3 moves upward and contacts the scraper 11, the first screw rod 2 stops rotating, and the second screw rod 9 rotates to make the sliding plate 10 drive the scraper 11 to move along the axial direction of the second screw rod 9, thereby cleaning the scraper 11 and the filter plate 3.

[0036] like Figure 4As shown, the winding assembly includes a first connecting plate 601 and a second connecting plate 602, and a mounting plate 603 is fixedly installed on the side of the first connecting plate 601 and the second connecting plate 602 that are away from each other. A connecting pipe 604 is provided between the first connecting plate 601 and the second connecting plate 602, and the connecting pipe 604 is fixedly connected to the first connecting plate 601 and the second connecting plate 602. A first fixing ring 605 is fixedly installed on the side of the second connecting plate 602 that is close to the first connecting plate 601, and a second fixing ring 606 is provided inside the first fixing ring 605. The first fixing ring 605 is connected to the second fixing ring 606. The fixing ring 606 is limited, and a third connecting plate 607 is fixedly installed on one side of the second fixing ring 606 away from the second connecting plate 602. A vortex spring sheet 608 corresponding to the second fixing ring 606 is arranged between the third connecting plate 607 and the second connecting plate 602. One end of the vortex spring sheet 608 is fixedly connected to the connecting pipe 604, and the other end of the vortex spring sheet 608 is fixedly connected to the second fixing ring 606. When the third connecting plate 607 rotates, the second fixing ring 606 pushes the vortex spring sheet 608 to deform, so that the third connecting plate 607 can be automatically reset.

[0037] like Figure 4 As shown, a plurality of support plates 609 are fixedly installed on one side of the third connecting plate 607 close to the first connecting plate 601, and the plurality of support plates 609 are distributed circumferentially about the center line of the third connecting plate 607. The plurality of support plates 609 are slidably connected to the first connecting plate 601, and the support plates 609 limit the third connecting plate 607. A second hose 610 is sleeved on the outer surface of the support plate 609, and one end of the second hose 610 is connected to the connecting pipe 604. The support plate 609 serves as a support for the second hose 610. A plurality of arc protection plates 611 are provided between the first connecting plate 601 and the second connecting plate 602, and the plurality of arc protection plates 611 are distributed circumferentially about the center line of the first connecting plate 601. The arc protection plates 611 are The primary function of 1 is to provide physical protection to protect the components below it from external impact, dust, impurities or accidental collision. At the same time, the arc-shaped protection plate 611 also plays a role of structural support, providing the necessary stability and strength for the spraying device 7 or other components, which helps to ensure the durability of the system under long-term use and harsh environmental conditions. The outer surface of the second hose 610 corresponding to the arc-shaped protection plate 611 is fixedly installed with a second limiting plate 612. The second limiting plate 612 cooperates with the arc-shaped protection plate 611 to prevent the spraying device 7 from being stored in the winding mechanism 6. When the staff pulls the spraying device 7, the second hose 610 drives the third connecting plate 607 on the support plate 609 to rotate, thereby allowing the second hose 610 to unfold.

[0038] like Figure 5-6As shown, the spraying device 7 includes a first fixed pipe 701, the first fixed pipe 701 is connected to the second hose 610, one end of the first fixed pipe 701 away from the second hose 610 is connected to the second fixed pipe 702, the second fixed pipe 702 is provided with a first rotating groove inside, the inner wall of the second fixed pipe 702 is fixedly installed with two fixed plates 703, the first rotating groove is located between the two fixed plates 703, the inner wall of the first rotating groove is provided with a first limiting groove 704, a rotating plate is provided inside the first rotating groove, a rotating ring 705 is fixedly installed inside the rotating plate corresponding to the first limiting groove 704, a second limiting groove 706 is provided inside the rotating ring 705, and the second limiting groove 706 is provided inside the rotating ring 705. A third limiting plate 707 is fixedly installed on the inner wall of the first limiting groove 704 corresponding to the positioning groove 706, and a plurality of through grooves 708 are opened inside the fixed plate 703. The plurality of through grooves 708 are distributed circumferentially about the center line of the fixed plate 703, and the through grooves 708 pass through the rotating plate. The end of the second fixed tube 702 away from the first fixed tube 701 is connected to the conical tube 709, and a guide rod 710 is fixedly installed on the side of the fixed plate 703 close to the conical tube 709. The staff rotates the rotating plate, and the rotating plate drives the rotating ring 705 to rotate along the first limiting groove 704. After the second limiting groove 706 contacts the third limiting plate 707, the through groove 708 is connected to allow water to flow through.

[0039] like Figure 3 As shown, a baffle is fixedly installed at one end of the first hose 5 close to the water tank 1, and the baffle further filters the water flow entering the first hose 5. At the same time, the baffle can effectively prevent the water flow from backflowing at the connection between the first hose 5 and the water tank 1.

[0040] like Figure 5-6 As shown, the outer surface of the rotating plate is provided with a plurality of grooves 12, which are distributed circumferentially about the center line of the rotating plate. The grooves 12 can increase the contact area between the staff and the rotating plate, making it easier for the staff to rotate the rotating plate.

[0041] like Figure 4 As shown, a plurality of fixing grooves 13 are provided through the interior of the mounting plate 603 , and the plurality of fixing grooves 13 are linearly distributed along the length direction of the mounting plate 603 . The staff can pass the bolts through the fixing grooves 13 to fix the winding mechanism 6 in a suitable position.

[0042] like Figure 3 As shown, a discharge trough 14 corresponding to the scraper 11 is provided on one side of the water storage tank 1 away from the first hose 5 . When the scraper 11 cleans the surface of the filter plate 3 , the scraper 11 pushes the impurities on the surface of the filter plate 3 .

[0043] like Figure 7 As shown, a valve 15 is provided inside the first hose 5 near one end of the winding mechanism 6 , and the staff controls the water flow in the first hose 5 to enter the connecting pipe 604 through the valve 15 .

[0044] Working principle: when there is no fire at the construction site, since the upper surface of the water storage tank 1 is provided with an opening, the water storage tank 1 can store rainwater on rainy days. At the same time, a water inlet pipe is provided on the side of the water storage tank 1, and the external water flow can supplement the water flow in the water storage tank 1 through the water inlet pipe. Several first screws 2 rotate at the same time, so that the filter plate 3 moves up and down along the axial direction of the first screw 2. When the filter plate 3 contacts the scraper 11, the second screw 9 rotates so that the sliding plate 10 drives the scraper 11 to move along the axial direction of the second screw 9, so that the impurities on the surface of the filter plate 3 leave through the discharge trough 14, so that the scraper 11 and the filter plate 3 are cleaned; when the construction site is on fire, the staff opens the valve 15, and the water flow in the water storage tank 1 enters the spraying device 7 through the first hose 5, the connecting pipe 604 and the second hose 610 in turn. When the staff moves the spraying device 7 to a suitable position, the tapered pipe 709 in the spraying device 7 is aimed at the fire point, and then the rotating plate is rotated so that The rotating plate drives the rotating ring 705 to rotate along the first limiting groove 704. After the second limiting groove 706 contacts the third limiting plate 707, several through grooves 708 are connected. The water storage tank 1, the first hose 5, the connecting pipe 604, the second hose 610 and the spraying device 7 constitute a large communicating vessel, ensuring that in the absence of a supercharger, the water flows through the first hose 5, the connecting pipe 604, the second hose 610, the first fixed pipe 701, the through groove 708 and the tapered pipe 709 to spray to the fire point in sequence; when the fire point is extinguished, the staff seals the multiple through grooves 708 by rotating the rotating plate, and at the same time brings the spraying device 7 close to the winding mechanism 6. The vortex spring sheet 608 that has been deformed in the winding mechanism 6 drives the third connecting plate 607 to rotate slowly, thereby realizing the automatic winding of the second hose 610. At the same time, the second limiting plate 612 cooperates with the arc-shaped protective plate 611 to prevent the spraying device 7 from being wound into the winding mechanism 6, thereby reducing the probability of damage to the equipment.
