Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a fire sprinkler head with adjustable spray direction. Background Technology

[0002] Fire sprinkler heads are important equipment widely used in fire protection systems of various buildings. Their function is to control the fire and reduce the temperature by spraying water mist when a fire occurs, thereby buying time for personnel evacuation and fire fighting and rescue. They are widely used in fire protection projects in engineering construction, mechanical and electrical equipment installation, decoration and maintenance, municipal construction and other fields.

[0003] In the prior art, Chinese Patent Application No. CN202321503682.9 discloses an adjustable fire sprinkler head, including a connecting pipe, a sprinkler head body, and a movable pipe. A positioning bolt is movably installed on the surface of the connecting pipe, and a water guide pipe is fixedly connected inside the connecting pipe. A movable pipe is movably installed between the water guide pipe and the connecting pipe. A threaded ring is fixedly connected to the bottom of the movable pipe, and a fixing ring is movably installed around the threaded ring. The sprinkler head body is fixedly connected to the bottom of the fixing ring. Through the cooperation of the connecting pipe, the movable pipe, and the threaded ring, the height of the sprinkler head body can be quickly adjusted by the operator. It also makes it easy for the operator to adjust the fire sprinkler head to a suitable height as needed, so as to better meet the needs of various installation heights and reduce the limitations of the device.

[0004] Based on the above information, it is clear that existing sprinkler heads spray water over a large area, making it impossible to control the spray direction. This prevents precise fire suppression in the initial stages of a fire, thus missing the opportunity to extinguish the fire. Therefore, we propose a fire sprinkler head with adjustable spray direction. Utility Model Content

[0005] The purpose of this utility model is to provide a fire sprinkler head with adjustable spray direction, so as to solve the problem mentioned in the background art that the existing sprinkler heads spray water over a large area, cannot control the spray direction, and cannot accurately spray fire extinguishing in the initial stage of a fire, thus missing the opportunity to extinguish the fire.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fire sprinkler head with adjustable spray direction, comprising a mounting plate, wherein multiple sets of mounting holes are equally spaced on the outer wall of the mounting plate, a sprinkler head is threadedly mounted on the outer wall of the mounting plate, and a water inlet pipe is threadedly mounted on the end of the sprinkler head, and an adjustment mechanism for adjusting the spray direction is provided on the outer wall of the mounting plate.

[0007] The adjustment mechanism includes a sensor and a controller fixedly installed on the outer wall of the mounting plate. A drive motor is fixedly installed on the outer wall of the mounting plate, and a drive gear is fixedly installed at the end of the drive motor. An adjustment cover is rotatably installed on the outer wall of the mounting plate, and a telescopic cover is slidably installed on the outer wall of the adjustment cover. A spray hole is opened on the outer wall of the telescopic cover. A driven gear is fixedly installed on the outer wall of the adjustment cover. A telescopic mechanism for adjusting the spray range is provided on the outer wall of the telescopic cover.

[0008] Furthermore, the sensor is electrically connected to the controller, and the controller is electrically connected to the drive motor.

[0009] Furthermore, the cross-section of the adjusting cover is annular, and the inner diameter of the adjusting cover is larger than the outer diameter of the spray head. The driven gear is located at the end of the adjusting cover, and the outer wall of the driven gear is meshed with the driving gear.

[0010] Furthermore, the outer wall of the telescopic cover fits into the inner wall of the adjusting cover, and the length of the telescopic cover is greater than the length of the adjusting cover, and the end of the telescopic cover is designed with an arc shape.

[0011] Furthermore, multiple sets of spray holes are evenly spaced on the outer wall of the telescopic cover, and the distribution range of the multiple sets of spray holes is set in an arc of 0°-30°.

[0012] Furthermore, the telescopic mechanism includes a limiting block fixedly installed on the inner wall of the adjusting cover, a limiting groove corresponding to the limiting block is opened on the outer wall of the telescopic cover, and a fixing bolt is threadedly installed on the outer wall of the adjusting cover.

[0013] Furthermore, two sets of limiting blocks are symmetrically arranged on the inner wall of the adjusting cover, and the length of the adjusting block is less than the thickness of the outer wall of the telescopic cover. The outer wall of the limiting block is in contact with the outer wall of the limiting groove. The limiting groove has a U-shaped cross-section, and one end of the limiting groove penetrates the top outer wall of the telescopic cover. The length of the limiting groove is set to correspond to the telescopic range of the telescopic cover.

[0014] Furthermore, the fixing bolt is located at the end of the adjusting cover, and the end of the fixing bolt is in contact with the outer wall of the telescopic cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This fire sprinkler head with adjustable spray direction can achieve precise and flexible adjustment of the spray direction through the setting of adjustment mechanism. When a fire occurs, the sensor can quickly capture the specific location information of the fire and transmit the signal to the controller. After the controller analyzes and processes the signal according to the preset program, it quickly starts the drive motor. The drive motor drives the drive gear to rotate. Since the drive gear meshes with the driven gear, the driven gear will drive the adjustment cover to rotate. The rotation of the adjustment cover causes the telescopic cover connected to it to rotate as well, thereby changing the orientation of the spray holes on the telescopic cover. This achieves precise adjustment of the spray direction, which allows the sprinkler head to accurately spray water mist to the fire source in the early stage of the fire, greatly improving the fire extinguishing efficiency and avoiding the situation where the best fire extinguishing opportunity is missed due to the inability of traditional sprinkler heads to control the spray direction, effectively reducing the losses caused by the fire.

[0017] Furthermore, by incorporating a telescopic mechanism, the height and spray range can be adjusted, and the telescopic cover can be easily disassembled and assembled, thus facilitating the installation and removal of the sprinkler head. The limiting block and limiting groove cooperate with each other; when the height of the telescopic cover needs adjustment, it can slide stably along the trajectory of the limiting groove on the inner wall of the adjusting cover, thereby changing its height. This change in height alters the distribution range of the spray holes, enabling flexible adjustment of the spray range to meet the needs of different fire scenarios. The fixing bolts on the outer wall of the adjusting cover, when tightened, tightly adhere to the outer wall of the telescopic cover, securing it in the desired position. When disassembly, maintenance, or replacement of the telescopic cover is required, simply loosening the fixing bolts allows for easy removal of the cover from the adjusting cover, facilitating convenient installation and removal. This ease of installation and removal also simplifies the overall installation and removal of the sprinkler head, making routine maintenance and troubleshooting easier for staff, and improving the equipment's efficiency and reliability.

[0025] 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.

[0026] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: a fire sprinkler head 3 with adjustable spray direction, including a mounting plate 1. Multiple sets of mounting holes 101 are evenly spaced on the outer wall of the mounting plate 1. A sprinkler head 3 is threaded onto the outer wall of the mounting plate 1, and a water inlet pipe 2 is threaded onto the end of the sprinkler head 3. An adjustment mechanism for adjusting the spray direction is provided on the outer wall of the mounting plate 1. The adjustment mechanism includes a sensor 4 and a controller 5 fixedly mounted on the outer wall of the mounting plate 1. A drive motor 7 is fixedly mounted on the outer wall of the mounting plate 1, and a drive gear 701 is fixedly mounted at the end of the drive motor 7. An adjustment cover 6 is rotatably mounted on the outer wall of the mounting plate 1, and a telescopic cover 8 is slidably mounted on the outer wall of the adjustment cover 6. The outer wall of the telescopic cover 8 has a spray direction adjustment mechanism. The nozzle 802 has a driven gear 601 fixedly installed on the outer wall of the adjusting cover 6. The sensor 4 is electrically connected to the controller 5, and the controller 5 is electrically connected to the drive motor 7. The adjusting cover 6 has a circular cross-section and the inner diameter of the adjusting cover 6 is larger than the outer diameter of the spray head 3. The driven gear 601 is located at the end of the adjusting cover 6, and the outer wall of the driven gear 601 meshes with the driving gear 701. The outer wall of the telescopic cover 8 is in contact with the inner wall of the adjusting cover 6, and the length of the telescopic cover 8 is greater than the length of the adjusting cover 6. The end of the telescopic cover 8 has an arc-shaped design. Multiple sets of spray holes 802 are evenly spaced on the outer wall of the telescopic cover 8, and the distribution range of the multiple sets of spray holes 802 is set in an arc of 0°-30°.

[0027] When a fire occurs, the sensor 4 on the outer wall of the mounting plate 1 will quickly detect the specific location and related information of the fire. The sensor 4 will transmit the captured signal to the controller 5 in the form of an electrical signal. After receiving the signal, the controller 5 will perform a comprehensive and detailed analysis of the signal according to the pre-set program. The controller 5 will immediately send a start command to the drive motor 7. After the drive motor 7 starts, the drive gear 701 at its end will start to rotate. Since the drive gear 701 and the driven gear 601 fixedly installed on the outer wall of the adjusting cover 6 mesh with each other, the rotation of the drive gear 701 will drive the driven gear 601 to rotate. When the driven gear 601 rotates, it will drive the adjusting cover 6 connected to it to rotate. The telescopic cover 8 is slidably installed on the outer wall of the adjusting cover 6. The rotation of the adjusting cover 6 will cause the telescopic cover 8 to rotate as well. As the telescopic cover 8 rotates, the direction of the spray holes 802 opened on its outer wall changes, thereby realizing the precise and flexible adjustment of the spray direction of the sprinkler head 3, ensuring that the water mist can be accurately sprayed to the fire source in the initial stage of the fire.

[0028] Example 2: Based on Example 1, a telescopic mechanism is also disclosed, the specific structure of which is as follows: The outer wall of the telescopic cover 8 is provided with a telescopic mechanism for adjusting the spray range. The telescopic mechanism includes a limiting block 602 fixedly installed on the inner wall of the adjusting cover 6. The outer wall of the telescopic cover 8 is provided with a limiting groove 801 corresponding to the limiting block 602. A fixing bolt 603 is threadedly installed on the outer wall of the adjusting cover 6. Two sets of limiting blocks 602 are symmetrically arranged on the inner wall of the adjusting cover 6. The length of the adjusting block is less than the thickness of the outer wall of the telescopic cover 8. The outer wall of the limiting block 602 is in contact with the outer wall of the limiting groove 801. The cross-section of the limiting groove 801 is U-shaped. One end of the limiting groove 801 penetrates the top outer wall of the telescopic cover 8. The length of the limiting groove 801 is corresponding to the telescopic range of the telescopic cover 8. The fixing bolt 603 is located at the end of the adjusting cover 6. The end of the fixing bolt 603 is in contact with the outer wall of the telescopic cover 8.

[0029] When the spray range of the sprinkler head 3 needs to be adjusted, the operator can loosen the fixing bolt 603 and manually push the telescopic cover 8, allowing it to slide stably along the trajectory of the limiting groove 801 on the inner wall of the adjusting cover 6. As the telescopic cover 8 extends and retracts, its height changes, and the distribution range of the spray holes 802 on the telescopic cover 8 also changes accordingly, thus achieving flexible adjustment of the spray range to adapt to the actual needs of different fire scenarios. After the telescopic cover 8 is adjusted to a suitable height and spray range, the operator can tighten the fixing bolt 603 on the outer wall of the adjusting cover 6 to secure it. The end of the fixing bolt 603 is tightly attached to the outer wall of the telescopic cover 8, generating sufficient friction to firmly fix the telescopic cover 8 in the required position. When the telescopic cover 8 needs to be disassembled for maintenance or replacement, the operator only needs to loosen the fixing bolt 603 in the opposite direction to release the binding force of the fixing bolt 603 on the telescopic cover 8, and the telescopic cover 8 can be easily removed from the adjusting cover 6. The convenient disassembly and assembly of the telescopic cover 8 also makes the entire disassembly and assembly process of the spray head 3 simpler and more efficient, making it easier for operators to carry out daily maintenance and troubleshooting, and improving the efficiency and reliability of the equipment.
