Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to an automatic tracking and positioning jet fire extinguishing device. Background Art

[0002] There is a fire extinguishing device that fixes a nozzle on an adjustable base. The adjustable base can provide the nozzle with a multi-angle rotation effect. A flame detector is installed on the nozzle. The flame is detected by the detector, and the direction of the nozzle is adjusted by the adjustable base so that it is directed towards the fire source for precise fire extinguishing.

[0003] The automatic tracking and positioning jet fire extinguishing device disclosed in the existing Chinese patent publication number CN212631531U is modified on the basis of the traditional automatic positioning and following fire extinguishing device. A rotating disk is installed at the end of the water spray pipe, and a plurality of nozzles of different specifications are arranged on the rotating disk. After determining the type of fire source, the rotating disk is rotated according to the type of fire source to switch different nozzles to align with the water spray pipe, so that the water spraying form of the water spray pipe can be adaptively adjusted according to the type of fire source. However, it was found in actual use that the automatic tracking and positioning jet fire extinguishing device disclosed in the Chinese patent publication number CN212631531U is modified on the basis of the traditional automatic positioning and following fire extinguishing device. A rotating disk is installed at the end of the water spray pipe, and a plurality of nozzles of different specifications are arranged on the rotating disk. After determining the type of fire source, the rotating disk is rotated according to the type of fire source to switch different nozzles to align with the water spray pipe, so that the water spraying form of the water spray pipe can be adaptively adjusted according to the type of fire source. The automatic tracking and positioning jet fire extinguishing device disclosed in the national patent still has certain problems. Its rotating disk is directly rotatably installed on the inner side of the connecting pipe, and no corresponding sealing structure is provided, which cannot ensure the sealing between the rotating disk and the connecting pipe. Even if a sealing ring structure is added, the sealing ring and the connecting pipe are still slidingly connected, and there is no axial pressure from the connecting pipe. As a result, when the water spraying fire extinguishing work is carried out, a large amount of water will flow out from the gap between the rotating disk and the connecting pipe, forming water leakage, thereby causing the water pressure finally sprayed to the fire source to drop, resulting in a decrease in the fire extinguishing effect. Utility Model Content

[0004] The utility model aims to provide an automatic tracking and positioning jet fire extinguishing device which solves the problem that the existing automatic tracking and positioning jet fire extinguishing device is prone to water leakage and reduces the fire extinguishing effect.

[0005] In order to solve the problems existing in the prior art, the technical solution of the present utility model is as follows:

[0006] An automatic tracking and positioning jet fire extinguishing device includes an adjustment base, a nozzle is fixed at the output end of the adjustment base, an adjustment disk is movably mounted on the end of the nozzle away from the adjustment base, a plurality of spray holes are provided on the adjustment disk at equal angular intervals, rubber sealing gaskets are fixed at positions corresponding to the spray holes on both sides of the adjustment disk, a rotating assembly for driving the adjusting disk to rotate is fixed on the outer wall of the nozzle, the adjusting disk is slidably mounted on the output end of the rotating assembly, a nozzle is movably mounted on the end of the nozzle close to the adjustment disk, the adjusting disk is located between the nozzle and the nozzle, and a pressing assembly for driving the nozzle to move and press the adjusting disk and press the adjusting disk against the liquid outlet end of the nozzle is mounted on the end of the nozzle close to the nozzle.

[0007] Preferably, the rotating assembly includes a connecting block fixed on the outer wall of one end of the nozzle close to the adjusting disk, the connecting block is rotatably connected to a rotating shaft through a bearing, a limiting ring is fixed to the end of the rotating shaft away from the adjusting base, the adjusting disk is slidably connected to the rotating shaft through a sliding hole, a spring is sleeved on the outer side of the end of the rotating shaft close to the adjusting disk, one end of the spring is in compression contact with the outer wall of the adjusting disk, and the other end of the spring is in compression contact with the outer wall of the connecting block, a motor is fixed on the outer wall of the nozzle close to the adjusting base, and the end of the rotating shaft close to the motor is fixedly connected to the output end of the motor.

[0008] Preferably, the pressing assembly includes an electric push rod fixed to the outer wall of one end of the nozzle close to the adjustment disk, and the protruding end of the electric push rod is fixed to the outer wall of the nozzle.

[0009] Preferably, the rotating assembly further comprises a lubrication assembly mounted on the connecting block for applying lubricating oil to the rubber sealing gasket.

[0010] The top end of the driving member is connected to the upper end of the driving member by a threaded hole, and the bottom end of the driving member is connected to the upper end of the driving member by a threaded hole.

[0011] Preferably, an annular groove is provided on the outer circumference of the adjusting disk, and a protrusion is fixed on the inner wall of the frame, and the protrusion is slidably inserted into the inner side of the annular groove.

[0012] Compared with the related art, the present invention has the following beneficial effects:

[0013] 1. During use, after determining the type of fire source, the adjusting disc is rotated by the rotating assembly to rotate until the appropriate nozzle hole is aligned with the nozzle. The pressing assembly then works to move the nozzle closer to the nozzle. Finally, the nozzle is pressed against the rubber sealing gasket on one side of the adjusting disc. The rubber sealing gasket on the other side of the adjusting disc is also pressed against the end of the nozzle, thereby forming an effective seal between the nozzle and the adjusting disc, and between the adjusting disc and the nozzle. In addition, there is a pressing force from the nozzle axis between the adjusting disc and the nozzle, and between the adjusting disc and the nozzle, thereby greatly reducing the probability of water leakage at the connection between the adjusting disc, the nozzle, and the nozzle, ensuring the water pressure during fire extinguishing and avoiding the fire extinguishing effect being reduced due to water leakage.

[0014] 2. At the same time, by setting up a lubrication component, lubricating liquid can be applied to the outside of the rubber sealing gasket during daily use, thereby effectively protecting the rubber sealing gasket, slowing down the aging of the rubber sealing gasket, and improving the sealing effect;

[0015] 3. Since the nozzle, nozzle and adjustment disk are separated during daily use, the rubber sealing gasket is not squeezed when no fire extinguishing work is performed, which can effectively slow down the aging speed of the rubber sealing gasket, further improve the service life of the rubber sealing gasket, and ensure its sealing effect during use.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1, please participate Figures 1 to 4 This embodiment provides an automatic tracking and positioning jet fire extinguishing device, comprising an adjustment base 1, a nozzle 2 being fixed to the output end of the adjustment base 1, an adjustment disk 3 being movably mounted on the end of the nozzle 2 away from the adjustment base 1, and four spray holes 4 being formed on the adjustment disk 3 at equal angles. Each spray hole 4 has a different shape, and the different shapes of the spray holes 4 produce different water flow shapes when facing the nozzle 2. The different shapes of the spray holes 4 are known in the art and will not be described in detail here.

[0028] Rubber sealing washers 5 are fixed to the positions of the nozzle holes 4 on both sides of the adjustment disk 3. A rotating assembly 6 for driving the adjustment disk 3 to rotate is fixed to the outer wall of the nozzle pipe 2. The adjustment disk 3 is slidably mounted on the output end of the rotating assembly 6. A nozzle 7 is also movably mounted on the end of the nozzle pipe 2 near the adjustment disk 3. The adjustment disk 3 is located between the nozzle 7 and the nozzle pipe 2.

[0029] The rotating assembly 6 includes a connecting block 61 fixed to the outer wall of the end of the nozzle 2 close to the adjustment disk 3, and a rotating shaft 62 is rotatably connected to the connecting block 61 through a bearing. A limiting ring 63 is fixed to the end of the rotating shaft 62 away from the adjustment base 1. The adjustment disk 3 is slidably connected to the rotating shaft 62 through a sliding hole. A spring 64 is sleeved on the outer side of the end of the rotating shaft 62 close to the adjustment disk 3. One end of the spring 64 is in press-contact with the outer wall of the adjustment disk 3, and the other end of the spring 64 is in press-contact with the outer wall of the connecting block 61. A motor 65 is fixed to the outer wall of the nozzle 2 close to the adjustment base 1, and the end of the rotating shaft 62 close to the motor 65 is fixedly connected to the output end of the motor 65;

[0030] When the nozzle 7, the adjustment disk 3, and the nozzle 2 are in a separated position, there is a certain gap between the nozzle 7 and the adjustment disk 3, and there is also a certain gap between the adjustment disk 3 and the nozzle 2. At this time, under the action of the spring 64, the adjustment disk 3 is pushed tightly against the limiting ring 63;

[0031] In actual use, the location of the fire source can be determined by installing a sensing probe on the outer wall of the nozzle 2. The sensing probe is not shown in the figure. This is a prior art and will not be described in detail here. When the sensing probe determines the location of the fire source, the base 1 is adjusted to control the nozzle 2 to adjust its angle toward the fire source. While the sensing probe senses the fire source, the condition of the fire source can be determined. During the process of adjusting the angle of the nozzle 2 by adjusting the base 1, the rotating assembly 6 works according to the condition of the fire source to rotate the adjusting disk 3, adjusting a nozzle hole 4 corresponding to the condition of the fire source to align with the nozzle 2.

[0032] The adjustment disk 3 rotates by driving the motor 65 to drive the shaft 62 to rotate, thereby driving the adjustment disk 3 to rotate.

[0033] A pressing assembly 8 is installed at one end of the nozzle 2 near the nozzle 7 for driving the nozzle 7 to move and press the adjustment disk 3 and press the adjustment disk 3 against the liquid outlet end of the nozzle 2. The pressing assembly 8 includes an electric push rod 81 fixed to the outer wall of the end of the nozzle 2 near the adjustment disk 3. The extended end of the electric push rod 81 is fixed to the outer wall of the nozzle 7.

[0034] After the adjustment of the adjusting disk 3 is completed, the electric push rod 81 is driven to retract, so that the nozzle head 7 is close to the adjusting disk 3, so that the nozzle head 7 is pressed against the rubber sealing gasket 5 on the outer wall of the adjusting disk 3. Then the electric push rod 81 continues to retract, and the nozzle head 7 pushes the adjusting disk 3, so that the adjusting disk 3 slides on the rotating shaft 62, and the nozzle head 7 and the adjusting disk 3 move together to the side close to the nozzle pipe 2. Finally, the rubber sealing gasket 5 on the side of the adjusting disk 3 close to the nozzle pipe 2 is pressed against the end of the nozzle pipe 2. Finally, the nozzle head 7 is pressed against the rubber sealing gasket 5 on the side of the adjusting disk 3 close to the nozzle head 7, and the rubber sealing gasket 5 on the side of the adjusting disk 3 close to the nozzle pipe 2 is pressed against the end of the nozzle pipe 2, thereby achieving a seal between the nozzle pipe 2, the adjusting disk 3 and the nozzle head 7.

[0035] Therefore, when spraying water to extinguish a fire, it is possible to effectively prevent water from overflowing from the connection between the regulating disk 3 and the nozzle 2, thereby ensuring the water pressure of the water spray during fire extinguishing and ensuring that the fire extinguishing effect will not be deteriorated due to water leakage.

[0036] Example 2, please participate Figures 5 to 7, this embodiment provides a further technical solution based on the first embodiment. The rotating assembly 6 also includes a lubricating assembly 9 installed on the connecting block 61 for applying lubricating oil to the rubber sealing gasket 5. The lubricating assembly 9 includes a delivery hard pipe 91 slidably connected to the connecting block 61 through a sliding hole. A frame 92 is fixed to one end of the delivery hard pipe 91 close to the adjusting disk 3. The frame 92 is sleeved on the outside of the adjusting disk 3, and the frame 92 is slidably connected to the adjusting disk 3. Sponges 93 are symmetrically fixed to the inner wall of the frame 92. The two sponges 93 are respectively in contact with the two sides of the adjusting disk 3. The delivery hard pipe 91 is close to the adjusting disk Two nozzles 94 are fixed on one side of 3, and the two nozzles 94 correspond to two sponges 93 respectively. A delivery hose 95 is connected to the end of the delivery hard tube 91 away from the adjustment disk 3. A storage tube 96 is fixed on the outer wall of the nozzle 2 near the end of the adjustment disk 3. The end of the delivery hose 95 is connected to the storage tube 96. A piston 97 is slidably inserted into the inner side of the storage tube 96. A connecting piece 98 is fixed to the end of the piston 97 away from the storage tube 96. The rotating shaft 62 is fixed to the output end of the motor 65 through a threaded rod 99 fixed between the end of the rotating shaft 62 and the output end of the motor 65. The connecting piece 98 is threadedly connected to the threaded rod 99 through a threaded hole.

[0037] Each time the base 1 adjusts the angle of the nozzle 2, the rotating assembly 6 drives the adjusting disk 3 to rotate and adjust the spray hole 4. The rotating assembly 6 can first drive the entire adjusting disk 3 to rotate 360 degrees. During the rotation, the motor 65 rotates and drives the threaded rod 99 to rotate, so that the connecting piece 98 drives the piston 97 to insert a distance into the inner side of the storage tube 96, thereby pushing the lubricant inside the storage tube 96 through the delivery hose 95 and the delivery hard tube 91 to be sprayed from the nozzle 94 to the two sponges 93. After the 360-degree rotation, the rotating assembly 6 enters the driving adjustment disk 3 to rotate to adjust the posture of the spray hole 4. During the entire rotation process, multiple rubber sealing gaskets 5 are all scratched from the surface of the sponge 93, so that the lubricant is wiped on the outer walls of all rubber sealing gaskets 5.

[0038] It should be emphasized that when the pressing assembly 8 is working, the nozzle 7 and the adjustment disk 3 move together toward one side of the nozzle 2. Since the adjustment disk 3 is slidably connected to the frame 92, the frame 92 and the delivery tube 91 can be driven to slide together by the adjustment disk 3. The delivery tube 91 slides on the connecting block 61. The outer wall of the delivery tube 91 close to the connecting block 61 is symmetrically formed with ridges. The arrangement of the ridges ensures that the delivery tube 91 can slide stably on the connecting block 61 without rotating.

[0039] Thus, the rubber sealing gasket 5 performs lubrication protection work, and in the daily use process, when the entire device is in a standby state and not performing fire extinguishing work, the motor 65 can also be regularly driven to rotate and lubricate the rubber sealing gasket 5;

[0040] Since the lubricant can be wiped onto the rubber sealing gasket 5 daily and before each fire extinguishing work, the rubber sealing gasket 5 can be protected, the aging of the rubber sealing gasket 5 can be slowed down, and the sealing effect of the rubber sealing gasket 5 can be guaranteed.

[0041] For example three, please refer to Figure 8 and Figure 9 This embodiment provides a further technical solution based on the second embodiment. An annular groove 11 is provided on the outer periphery of the adjusting disk 3, and a protrusion 10 is fixed on the inner wall of the frame 92. The protrusion 10 is slidably inserted into the inner side of the annular groove 11. The sliding connection effect between the adjusting disk 3 and the frame 92 is achieved through the protrusion 10 and the annular groove.

[0042] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
