Description

Technical Field

[0001] This utility model relates to the field of chemical safety technology, and in particular to a fire sprinkler system for chemical safety. Background Technology

[0002] In chemical production processes, fire sprinkler systems are needed to cope with potential accidents on oil storage tanks. For example, a fire sprinkler system for chemical safety production, publication number CN220877588U, includes a mounting plate. A fixed hose is connected to the mounting plate via a fixed flange. A spray pipe is fixedly connected to the lower part of the fixed hose, and a spray hole is provided at the lower part of the spray pipe. A slide rail is fixedly connected to the mounting plate, and a slide block is slidably connected to the slide rail. A fixed pulley is fixedly installed at the lower part of the slide block. A control component is fixedly connected to the spray pipe. The device is fixedly connected by a connecting rope, which passes over a fixed pulley and is fixedly connected to a counterweight hook. In use, the connecting rope is pulled down by the counterweight hook. The connecting rope drives the control component to move through the fixed pulley. The control component moves the spray pipe completely in the direction of the pulling of the connecting rope. If it is necessary to change the spray direction, a lateral force is applied, giving the slide block a horizontal component force, which causes the slide block to slide on the slide rail. This allows the spray pipe to be changed to any direction, with a wide range of adjustment. In case of emergency, if personnel need to evacuate, a heavy object can be hung on the counterweight hook to act as a pulling force for personnel.

[0003] Manually pulling the counterweight hook allows for real-time adjustment of the nozzle's direction and angle, offering high flexibility. However, in emergency situations where a suspended weight replaces manual operation, the nozzle's direction and angle become fixed and cannot be adjusted. If an adjustment is needed, the weight must be removed and the adjustment repeated, which may be inconvenient in practice. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a fire sprinkler device for chemical safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire sprinkler device for chemical safety, comprising a fixed base and a sprinkler head. A hollow tube is rotatably connected through the center of the bottom surface of the fixed base. A rotating base is fixedly installed at the bottom end of the hollow tube. A spur gear driven by electricity is rotatably connected to one side of the outer wall of the rotating base. A water outlet pipe for installing the sprinkler head is fixedly installed at the center of one end of the spur gear, extending inward through the side of the rotating base. The water outlet pipe is L-shaped, with its inlet end coaxial with the spur gear and extending through the other side of the rotating base. A water inlet pipe penetrating the hollow tube is installed through a rotary joint at the inlet end of the water outlet pipe. A toothed ring coaxially distributed and driven by electricity is fixedly installed on the outer wall of the hollow tube near the bottom surface of the fixed base.

[0006] Preferably, the portion of the water pipe located inside the hollow tube is vertically upward and coaxially distributed with the hollow tube, and the other end of the water pipe is also connected to a water inlet pipe via a rotary joint.

[0007] Preferably, the rotary joint at one end of the water pipe is coaxially distributed with the spur gear, and the portion of the water pipe outside the hollow tube is U-shaped and offset from the rotating seat.

[0008] Preferably, a motor is fixedly installed on the upper surface of the fixed base near the gear ring, and the motor spindle passes through the upper surface of the fixed base and is fixedly installed with a drive gear that meshes with the gear ring.

[0009] Preferably, a plurality of electric push rods are fixedly installed around the hollow tube on the lower surface of the fixed base. The electric push rods are arranged perpendicular to the lower surface of the fixed base, and the telescopic ends of the plurality of electric push rods are fixedly installed with the same lifting ring.

[0010] Preferably, a rotating ring is rotatably connected to the inner side of the lifting ring, and a connecting rod is fixedly installed on one side of the bottom end of the rotating ring. A rack perpendicular to the lower surface of the fixed seat and meshing with a spur gear is fixedly installed at the bottom end of the connecting rod.

[0011] Preferably, one side of the rack is inserted into the outer wall of the rotating seat, and the cross-section of the insertion point is L-shaped.

[0012] Preferably, an anti-slip washer is fixedly installed on the upper surface edge of the fixing seat, and a plurality of expansion bolts passing through the sealing washer are provided through the lower surface edge of the fixing seat, and the water inlet end of the water inlet pipe is provided through the inner side of the sealing washer.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an electric drive spur gear and an electric drive gear ring, the gear ring can drive the hollow tube and the rotating seat to rotate, thereby enabling the water outlet pipe to drive the spray head to rotate around the fixed seat to adjust its orientation. The spray head's tilt angle can be adjusted by the electric drive spur gear driving the water outlet pipe to revolve within the rotating seat. In other words, this solution uses electric drive to drive the spray head to revolve and rotate, which is convenient for remote control by personnel.

[0014] 2. In this utility model, by setting up a lifting ring and a rotating ring, and utilizing the insertion of the rack and the rotating seat, the rotating seat rotates, causing the rack to revolve around the central axis of the fixed seat. When the rack revolve, it causes the rotating ring to rotate around the central axis of the fixed seat within the lifting ring. During the rotation of the rotating ring, the lifting ring is driven to rise and fall by the extension and retraction of the electric push rod, which allows the spray head to revolve and the tilt angle to be adjusted simultaneously.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figures 1-4As shown, a fire sprinkler system for chemical safety includes a fixed base 1 and a sprinkler head 10. A hollow tube 14 is rotatably connected through the center of the bottom surface of the fixed base 1. A rotating base 11 is fixedly installed at the bottom end of the hollow tube 14. The rotating base 11 rotates around the central axis of the fixed base 1. A spur gear 8 driven by electricity is rotatably connected to one side of the outer wall of the rotating base 11. A water outlet pipe 9 for installing the sprinkler head 10 is fixedly installed through the center of one end of the spur gear 8, extending inward through the side of the rotating base 11. By driving the spur gear 8 to rotate, the water outlet pipe 9 can swing within the rotating base 11. In conjunction with the rotation of the rotating base 11, the tilted water outlet pipe 9 revolves around the central axis of the fixed base 1, allowing the sprinkler head 10 to revolve and adjust its orientation at any tilt angle, or to achieve different tilts of the sprinkler head 10 when the orientation is fixed. Several electric push rods are fixedly installed around the hollow tube 14 on the lower surface of the fixed base 1. 5. The electric push rod 5 is set perpendicular to the lower surface of the fixed base 1, and the same lifting ring 16 is fixedly installed on the telescopic ends of several electric push rods 5. The inner side of the lifting ring 16 is rotatably connected to the rotating ring 15. A connecting rod 6 is fixedly installed on one side of the bottom end of the rotating ring 15. A rack 7 is fixedly installed at the bottom end of the connecting rod 6, perpendicular to the lower surface of the fixed base 1 and meshing with the spur gear 8. One side of the rack 7 is inserted into the outer wall of one side of the rotating base 11, and the cross section of the insertion point is set in an L shape. By utilizing the insertion of the rack 7 into the rotating base 11, when the rotating base 11 rotates, it drives the rack 7 to revolve around the central axis of the fixed base 1. When the rack 7 revolve, it drives the rotating ring 15 to rotate around the central axis of the fixed base 1 within the lifting ring 16. During the rotation of the rotating ring 15, the extension and retraction of the electric push rod 5 realizes the lifting ring 16 driving the rotating ring 15 to rise and fall, so that the rotation and tilt adjustment of the spray head 10 can be carried out simultaneously.

[0020] The water outlet pipe 9 is L-shaped, with its inlet end coaxial with the spur gear 8 and passing through the other side of the rotating seat 11. This facilitates smooth rotation of the water outlet pipe 9 within the rotating seat 11 for tilt adjustment. A water inlet pipe 17, passing through the hollow tube 14, is connected to the inlet end of the water outlet pipe 9 via a rotary joint. This rotary joint ensures smooth rotation of the water outlet pipe 9 within the rotating seat 11 for tilt adjustment. The portion of the water inlet pipe 17 inside the hollow tube 14 is vertically upward and coaxial with the hollow tube 14. When the rotating seat 11 rotates on the lower surface of the fixed seat 1, it smoothly drives the water inlet pipe 17 and the hollow tube 14 to rotate. The other end of the water inlet pipe 17 is also connected via a rotary joint to the inlet pipe 4 and the spur gear at one end of the water inlet pipe 17. The wheels 8 are coaxially distributed. The water pipe 17 located outside the hollow tube 14 is U-shaped and offset from the rotating seat 11. The offset distribution ensures that the rotating seat 11 can rotate smoothly and the water outlet pipe 9 inside the rotating seat 11 can tilt smoothly. A coaxially distributed and electrically driven gear ring 13 is fixedly installed on the outer wall of the hollow tube 14 near the bottom surface of the fixed seat 1. A motor 3 is fixedly installed on the upper surface of the fixed seat 1 near the gear ring 13. The main shaft of the motor 3 passes through the upper surface of the fixed seat 1 and a drive gear 12 that meshes with the gear ring 13 is fixedly installed. In actual use, the motor 3 drives the drive gear 12 to rotate, which enables the meshing gear ring 13 to drive the hollow tube 14 to rotate, thus achieving synchronous rotation of the rotating seat 11.

[0021] An anti-slip washer 2 is fixedly installed on the upper edge of the fixed base 1, and several expansion bolts passing through the sealing washer are provided through the lower edge of the fixed base 1. The water inlet end of the water inlet pipe 4 is provided through the inner side of the sealing washer. The anti-slip washer 2 can increase the friction between the fixed base 1 and the installation position. With the support of the expansion bolts, the anti-slip washer 2 can be smoothly and tightly attached to the installation position. The anti-slip washer 2 is used to fix the position of the water inlet pipe 4. The swivel joint at one end of the connecting pipe can make the hollow pipe 14 rotate smoothly around the central axis of the fixed base 1.

[0022] The method of using this utility model is as follows: The spray head 10 is spirally installed at the bottom of the water outlet pipe 9. In actual use, the motor 3 drives the drive gear 12 to rotate, so that the gear ring 13 drives the hollow tube 14 and the rotating seat 11 to rotate. This allows the spray head 10 to revolve around the central axis of the fixed seat 1. During the rotation and orientation adjustment, the electric push rod 5 is extended and retracted to drive the lifting ring 16 to drive the rotating ring 15 to rise and fall. This allows the rotating ring 15 to drive the rack 7 to rise and fall during the rotation process, and the meshing spur gear 8 to drive the water outlet pipe 9 and the spray head 10 to adjust their tilt angle.

[0023] The wiring diagrams of the motor 3 and electric push rod 5 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the motor 3 and electric push rod 5 will not be explained in detail.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
