Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, and more specifically to a water spray head for fire fighting. Background Art

[0002] In construction and life, fire safety issues are of paramount importance. When a fire is discovered, a complete fire-fighting device can better target and suppress the fire. In existing buildings, firefighting usually uses fire extinguishers or fire hydrants. Fire hydrants are mostly boxes installed on the wall, which contain fire switches, spirally placed fire pipes and fire sprinklers. When extinguishing a fire, take out the fire sprinkler and turn on the fire switch to aim the fire sprinkler at the fire source for extinguishing. This method requires firefighters to hold the fire sprinkler to extinguish the fire, so one firefighter can only operate one fire sprinkler, which is less efficient. In addition, in a fire, the oxygen content is low, and the weight of the fire sprinkler with water flowing through it will bring a greater burden to the firefighters. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be combined with the technical solution in the embodiments of the utility model for a clear and complete description. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] In this embodiment, a fire sprinkler head is combined with Figure 1 — Figure 6As shown, it includes a water spray structure 1, a first adjustment structure 2 and a second adjustment structure 3. The first adjustment structure 2 for adjusting the angle of the water spray structure 1 is installed on the water spray structure 1, and the second adjustment structure 3 for adjusting the tilt angle of the water spray structure 1 is installed below the first adjustment structure 2. The first adjustment structure 2 and the second adjustment structure 3 can be used to adjust the water spray direction of the water spray structure 1 to better target the fire. The water spray structure 1 includes a nozzle 11. The main body of the nozzle 11 is a cylindrical structure. One end of the nozzle 11 is conical. By using the conical structure, its inner diameter can be changed to achieve the function of accelerating the water flow. The other end of the nozzle 11 is provided with a mounting pipe for connecting a water pipe. The mounting pipe is in the shape of a bamboo joint, and a triangular cross-section is provided thereon to prevent the water pipe from falling off. The nozzle 11 is provided with a stopper 13, and the stopper 13 is installed in the nozzle 11 through an axis. The edge of the stopper 13 is rounded, and the stopper 13 can be turned over in the nozzle 11. The diameter of the stopper 13 is not larger than the inner diameter of the nozzle 11. The stopper 13 is wrapped with a sealing ring, and the sealing ring is fixedly installed on the stopper 13. The sealing ring is preferably made of rubber material. The stopper 13 contacts the inner diameter of the nozzle 11 through the sealing ring, so that when the stopper 13 is closed, the water flow can be cut off. A turntable 14 for controlling the turning of the stopper 13 is coaxially installed on the axis of the stopper 13. The turntable 14 can drive the stopper 13 to turn over, thereby realizing the turning of the stopper 13. The rotating disk 14 is controlled by the control device, and an anti-slip protrusion is arranged on the circumferential wall of the rotating disk 14. A rotating shaft 16 is installed on the circumferential wall of the nozzle 11. The nozzle 11 is installed on the first adjustment structure 2 through the rotating shaft 16. The first adjustment structure 2 includes a supporting platform 24 for installing the rotating shaft 16. The rotating shaft 16 is installed on the supporting platform 24 to support and fix the nozzle 11. Therefore, the position of the nozzle can be fixed by placing the supporting platform 24, thereby freeing both hands, and the operator does not need to hold the nozzle 11 to extinguish the fire. The rotating shaft 16 can rotate freely on the supporting platform 24, so that the direction of the nozzle 11 can be adjusted. Since the weight of the nozzle 11 increases after water is passed through, in order to improve the supporting force for placing the nozzle 11, an arc-shaped mounting groove 15 is arranged on the rotating disk 14. The arc The arc-shaped mounting groove 15 is connected to the first adjustment structure 2, and the first adjustment structure 2 includes a support rod 22, and the support rod 22 is installed on the arc-shaped mounting groove 15 through a connecting column 21. A tray 26 for supporting the support rod 22 is provided below the support rod 22, and the stopper 13 is driven to move during the rotation of the turntable 14. When the stopper 13 is closed, the support rod 22 is in a raised state. Since the water flow is cut off, the overall weight of the nozzle 11 is relatively low at this time, so there is no need for the support rod 22 to support the nozzle 11. The stopper 13 is driven to move during the rotation of the turntable 14. When the stopper 13 is opened, the support rod 22 falls on the tray 26. Since the water flow passes through the nozzle 11, the overall weight of the nozzle 11 is relatively large. At this time, the support rod 22 plays a role in supporting the nozzle 11.Make it more stable.

[0028] Example 2

[0029] Based on Example 1, in this example, Figure 4 — Figure 6 As shown, the support platform 24 is fixedly mounted on the tray 26 by a mounting frame 25, and an annular groove is provided on the circumferential wall of the support platform 24, and the annular groove is concentrically arranged with the support platform 24, and a slider 23 is installed in the annular groove, and the slider 23 can slide freely in the annular groove, and the end of the slider 23 away from the annular groove is installed on the support rod 22, and the support rod 22 is provided with a slide groove for installing the slider 23, and the slide groove is a long strip slide groove arranged along the length direction of the support rod 22, and the slider 23 can slide freely in the slide groove. Such an arrangement can make the rotation of the spray head 11 and the opening and closing movement of the stopper 13 not interfere with each other, and at the same time can prevent the support rod 22 from tilting due to the force of the turntable 14, and the tray 26 is provided with an annular groove for limiting the movement trajectory of the support rod 22, and the support rod 22 is located in the annular groove when in contact with the tray 26, and the support rod 22 and the arc The contact surface of the groove is a spherical surface, and the spherical surface can be used to reduce the friction between the support rod 22 and the arc groove. A spherical connector 31 is provided under the tray 26, and a spherical sleeve 32 is mounted on the spherical connector 31. The spherical connector 31 can rotate in the spherical sleeve 32, and the spherical sleeve 32 is installed on the base 34. No less than four springs 33 are installed between the base 34 and the tray 26. The springs 33 can support the tray 26, and the inclination angle of the nozzle 11 can be adjusted by pressing the nozzle 11 to squeeze the springs 33. The nozzle 11 is provided with a handle 12 for adjusting the head, and the nozzle 11 can be adjusted by applying pressure or torque to the handle 12. Such a configuration enables the device to be operated with one hand, so it is more efficient for one person to operate two devices. The base 34 can be placed on the ground, and does not require the operator to hold it, which is more labor-saving.

[0030] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
