Description

Technical Field

[0002] Currently, common indoor fire sprinkler systems include fire sprinkler heads and fire nozzles. Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head's splash plate to extinguish the fire. However, a single ordinary fire sprinkler head can only cover a fixed local area and cannot flexibly extinguish fires in other areas. Moreover, it only extinguishes fires by spraying water. On the other hand, fire nozzles have a single spray pattern and poor overall fire extinguishing adaptability. Therefore, we propose a fire sprinkler system. Summary of the Invention

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0023] Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a fire-fighting sprinkler device, which includes a main spray pipe 1, a secondary spray mechanism 2, a linkage mechanism 3, and an anti-blocking mechanism 4. The angle between the secondary spray mechanism 2 and the main spray pipe 1 is adjusted according to different fire conditions. The anti-blocking mechanism 4 can prevent the main spray pipe 1 from being covered by impurities in the water and forming dirt on the pipe wall during long-term use.

[0024] Specifically, the fire sprinkler system includes a main sprinkler pipe 1, a secondary sprinkler mechanism 2, a linkage mechanism 3, and an anti-clogging mechanism 4. One end of the main sprinkler pipe 1 is equipped with a first stop valve 1a, and a nozzle 1b is fixedly installed at the top of the first stop valve 1a. The other end of the main sprinkler pipe 1 is equipped with an installation ring 1c, and a threaded connector 1c-1 is installed at the bottom of the installation ring 1c. The anti-clogging mechanism 4 includes an anti-clogging pipe 4a threadedly connected to the threaded connector 1c-1. An anti-clogging component 4b is installed inside the anti-clogging pipe 4a. The bottom end of the anti-clogging pipe 4a is connected to a liquid inlet pipe 4c. A first inlet connector 4c-1 is installed on one side of the liquid inlet pipe 4c. The bottom end of the liquid inlet pipe 4c is connected to a collection pipe 4d, and a sealing cap 4d-1 is threadedly connected to the bottom end of the collection pipe 4d. The secondary sprinkler mechanism 2 includes... A mounting ring 2a and a fixing ring 2b are fixed to one side of the main nozzle 1. The outer wall of the mounting ring 2a has several concave seats 2c evenly distributed around its circumference. A transmission gear 2c-1 is rotatably installed inside the concave seat 2c. A connecting rod 2c-2 is installed on the outside of the transmission gear 2c-1. One end of the connecting rod 2c-2 is connected to the water supply pipe 2d. The other end of the water supply pipe 2d is equipped with an atomizing nozzle 2d-1. The top of the fixing ring 2b is equipped with an annular pipe 2e. The annular pipe 2e is connected to several water supply pipes 2d through several water supply hoses 2e-1. The side of the annular pipe 2e is connected to a straight pipe 2e-2. A second water stop valve 2e-3 is installed on the straight pipe 2e-2. A second liquid inlet connector 2e-4 is installed at the end of the straight pipe 2e-2.

[0025] Connect the external water pipe to the first inlet connector 4c-1 on the infusion pipe 4c. Water flows through the infusion pipe 4c and the anti-clogging pipe 4a into the main nozzle 1 and is sprayed out from the nozzle 1b. The anti-clogging component 4b inside the anti-clogging pipe 4a can filter and clean impurities in the water. Connect the external water pipe to the second inlet connector 2e-4 at the end of the straight pipe 2e-2. Water flows through the annular pipe 2e into the water infusion pipe 2d and is then sprayed out from the atomizing nozzle 2d-1.

[0026] Preferably, a linkage ring 2f is slidably sleeved on the outer wall of the main nozzle 1 at a position between the mounting ring 2a and the fixing ring 2b. Several positioning rings 2f-1 are provided on the outer side of the linkage ring 2f at positions corresponding to several concave seats 2c. Several water supply hoses 2e-1 are respectively inserted into the inner side of several positioning rings 2f-1.

[0027] Inserting several water supply hoses 2e-1 into the inside of several positioning rings 2f-1 can prevent the water supply hoses 2e-1 from being placed in an overlapping manner and thus bent, which would cause the water flow in the water supply hoses 2e-1 to be obstructed and affect the use effect.

[0028] Preferably, a baffle 2f-2 is provided on the side of the linkage ring 2f, and a number of toothed plates 2f-3 are erected on the top of the linkage ring 2f at positions corresponding to a number of concave seats 2c. The toothed plates 2f-3 are inserted into the concave seats 2c and mesh with the transmission gear 2c-1.

[0029] The spray angle of the atomizing nozzle 2d-1 can be adjusted according to the needs of the fire. When the toothed plate 2f-3 moves up or down, it can drive the rotation of the transmission gear 2c-1, thereby adjusting the spray angle of the atomizing nozzle 2d-1.

[0030] Preferably, a mounting base 2b-1 is provided on the side of the fixing ring 2b at a position corresponding to the baffle 2f-2, and an electric push rod 2b-2 is provided on the mounting base 2b-1. The telescopic rod end of the electric push rod 2b-2 is fixedly connected to the baffle 2f-2.

[0031] The telescopic rod of the electric push rod 2b-2 can be controlled to extend and retract, thereby controlling several toothed plates 2f-3 to move up or down simultaneously.

[0032] Preferably, the linkage mechanism 3 includes an adjusting plate 3a disposed inside the nozzle 1b, a bearing 3c disposed on the inner wall of the nozzle 1b, an adjusting cover 3b fixed in the inner ring of the bearing 3c, the bottom end of the adjusting cover 3b being in contact with the top end of the adjusting plate 3a, a main water spray hole 3d being provided in the middle of the top end of the adjusting plate 3a and the bottom end of the adjusting cover 3b, and a number of auxiliary water spray holes 3e being evenly distributed circumferentially around the main water spray hole 3d at the top end of the adjusting plate 3a and the bottom end of the adjusting cover 3b.

[0033] Since the top of the regulating plate 3a and the regulating cover 3b are both equipped with a main water spray hole 3d and several auxiliary water spray holes 3e at the same position, when the top of the regulating plate 3a and the regulating cover 3b rotate, causing the several auxiliary water spray holes 3e to be misaligned, water can only be sprayed from the main water spray hole 3d. With the water pressure remaining constant, the smaller the outlet area, the faster the sprayed water flow, which can reach the fire point at a greater distance. At the same time, the high-speed water flow is more conducive to fire extinguishing. When the top of the regulating plate 3a and the regulating cover 3b continue to rotate, causing the several auxiliary water spray holes 3e on the top of the regulating plate 3a and the regulating cover 3b to overlap, water is sprayed from the main water spray hole 3d and the several auxiliary water spray holes 3e, with a larger spray range, which can spray water to extinguish fires in a larger area.

[0034] Preferably, the top of the adjusting cover 3b is provided with a toothed ring 3b-1, and a guide plate 3f is provided on one side of the toothed ring 3b-1. The end face of the guide plate 3f is provided with an inclined groove 3f-1. The water supply pipe 2d is slidably disposed in the inclined groove 3f-1. A fixing block 3g is provided on the lower outer wall of the nozzle 1b. A T-shaped groove 3g-1 is provided on the side wall of the fixing block 3g. A snap-fit ​​rod 3f-2 is provided on the back of the guide plate 3f. The end of the snap-fit ​​rod 3f-2 is slidably snapped into the T-shaped groove 3g-1. A rack 3f-3 is provided at the top of the guide plate 3f. The rack 3f-3 meshes with the toothed ring 3b-1.

[0035] Since the water supply pipe 2d is slidably installed in the inclined groove 3f-1, when the water supply pipe 2d rotates up and down, it can drive the guide plate 3f to move left and right. When the guide plate 3f moves left and right, since the top of the guide plate 3f is provided with a rack 3f-3 that meshes with the toothed ring 3b-1, the rack 3f-3 drives the toothed ring 3b-1 to rotate forward or backward. The toothed ring 3b-1 then drives the regulating cover 3b to rotate. By controlling the rotation of the regulating cover 3b, the misalignment between the regulating plate 3a and the several auxiliary water spray holes 3e on the regulating cover 3b can be controlled.

[0036] In use, connect the external water pipe to the first inlet connector 4c-1 on the infusion pipe 4c. Water flows through the infusion pipe 4c and the anti-clogging pipe 4a into the main nozzle 1 and is sprayed out from the nozzle 1b. Connect the external water pipe to the second inlet connector 2e-4 at the end of the straight pipe 2e-2. Water flows through the annular pipe 2e into the water supply pipe 2d and is then sprayed out from the atomizing nozzle 2d-1. When the fire area is relatively large, extend the telescopic rod of the electric push rod 2b-2 to move the toothed plate 2f-3 upward, driving the rotation of the transmission gear 2c-1. This, in turn, increases the angle between the water supply pipe 2d and the main nozzle 1, resulting in a larger spray angle for the atomizing nozzle 2d-1 on the water supply pipe 2d. This expands the fire extinguishing range and reduces heat radiation for the operator. Simultaneously, as the water supply pipe 2d rotates downwards, it causes the guide plate 3f to move to the right. The rack 3f-3 at the top of the guide plate 3f drives the gear ring 3b-1 to rotate, which in turn drives the adjusting cover 3b to rotate until the adjusting cover 3b and several auxiliary spray holes 3e on the adjusting plate 3a are completely aligned. With the nozzles fully misaligned, water sprays from the main nozzle 3d and several auxiliary nozzles 3e, covering a wider area for fire extinguishing. When the fire is small, with only a few remaining ignition points, the telescopic rod of the electric push rod 2b-2 is shortened, causing the toothed plate 2f-3 to move downwards. This drives the transmission gear 2c-1 to rotate, reducing the angle between the water supply pipe 2d and the main nozzle 1. Consequently, the spray angle of the atomizing nozzles 2d-1 on the water supply pipe 2d also decreases. Simultaneously, the water supply pipe 2d... When the upper part rotates, it drives the guide plate 3f to move to the left. The rack 3f-3 at the top of the guide plate 3f drives the gear ring 3b-1 to rotate. The gear ring 3b-1 then drives the regulating cover 3b to rotate in the opposite direction until the regulating cover 3b and several auxiliary water spray holes 3e on the regulating plate 3a are completely aligned. At this time, the water can only be sprayed out from the main water spray hole 3d. With the water pressure unchanged, the outlet area becomes smaller, and the sprayed water speed is faster, which can spray to the fire point at a greater distance. At the same time, the high-speed water flow is more conducive to fire extinguishing. Example 2

[0037] Reference Figures 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the anti-clogging component 4b includes a placement frame 4b-1 disposed within the anti-clogging tube 4a, a filter screen 4b-2 disposed within the placement frame 4b-1, a spiral blade 4b-3 rotatably disposed at the bottom end of the filter screen 4b-2, and a scraper 4b-4 disposed at the top end of the spiral blade 4b-3, the scraper 4b-4 being in contact with the filter screen 4b-2.

[0039] When the external water pipe is connected to the first inlet connector 4c-1 on the infusion pipe 4c, the filter screen 4b-2 in the anti-clogging pipe 4a can filter large particulate impurities in the water, and the flow of water can drive the spiral blade 4b-3 to rotate. When the spiral blade 4b-3 rotates, the scraper 4b-4 at the top of the spiral blade 4b-3 can scrape off the filter residue from the filter screen 4b-2 to prevent the filter screen 4b-2 from being blocked by impurities. After the fire extinguishing operation is completed, open the sealing cap 4d-1 connected to the threaded end of the collection pipe 4d to discharge the water mixed with impurities from the collection pipe 4d in a timely manner.

[0040] In use, connect the external water pipe to the first inlet connector 4c-1 on the infusion pipe 4c. Water flows through the infusion pipe 4c and the anti-clogging pipe 4a into the main nozzle 1 and is sprayed out from the nozzle 1b. Connect the external water pipe to the second inlet connector 2e-4 at the end of the straight pipe 2e-2. Water flows through the annular pipe 2e into the water supply pipe 2d and is then sprayed out from the atomizing nozzle 2d-1. When the fire area is relatively large, extend the telescopic rod of the electric push rod 2b-2, causing the toothed plate 2f-3 to move upward, driving the rotation of the transmission gear 2c-1, which in turn increases the angle between the water supply pipe 2d and the main nozzle 1, thus increasing the spray from the atomizing nozzle 2d-1 on the water supply pipe 2d. The angle also increases, resulting in a larger spray range for fire extinguishing. The sprayed water mist also reduces heat radiation for the operator. Simultaneously, as the water pipe 2d rotates downwards, it moves the guide plate 3f to the right. The rack 3f-3 at the top of the guide plate 3f drives the gear ring 3b-1 to rotate, which in turn drives the adjusting cover 3b to rotate until the adjusting cover 3b and several auxiliary spray holes 3e on the adjusting plate 3a are completely misaligned. At this point, water is sprayed from the main spray hole 3d and several auxiliary spray holes 3e, resulting in a larger spray range, allowing for fire extinguishing of a larger area. When the fire is small, with only a few remaining ignition points, the electric push rod 2b-2 is controlled. The telescopic rod is shortened, causing the toothed plate 2f-3 to move downwards. This drives the transmission gear 2c-1 to rotate, which in turn reduces the angle between the water supply pipe 2d and the main nozzle 1. Consequently, the spray angle of the atomizing nozzle 2d-1 on the water supply pipe 2d also decreases. Simultaneously, as the water supply pipe 2d rotates upwards, it drives the guide plate 3f to move to the left. The rack 3f-3 at the top of the guide plate 3f drives the toothed ring 3b-1 to rotate. The toothed ring 3b-1 then drives the adjusting cover 3b to rotate in the opposite direction until the adjusting cover 3b and several auxiliary spray holes 3e on the adjusting plate 3a completely overlap. At this point, water can only be sprayed from the main spray hole 3d, while the water pressure remains constant. When the outlet area is smaller, the water jet speed is faster and can reach a farther fire point. At the same time, the high-speed water jet is more conducive to fire extinguishing. The filter screen 4b-2 in the anti-clogging pipe 4a can filter large particles of impurities in the water. The water flow can drive the spiral blade 4b-3 to rotate. When the spiral blade 4b-3 rotates, the scraper 4b-4 at the top of the spiral blade 4b-3 can scrape off the filter screen 4b-2 to prevent the filter screen 4b-2 from being blocked by impurities. After the fire extinguishing operation is completed, open the sealing cap 4d-1 at the bottom threaded connection of the collection pipe 4d to discharge the water mixed with impurities from the collection pipe 4d in a timely manner.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
