Description

Technical Field

[0001] This utility model relates to the field of chemical safety technology, and in particular to a chemical safety fire-fighting device. Background Technology

[0002] Chemical safety fire protection equipment is an important fire protection device in chemical plants. Fire protection devices such as fire sprinklers can respond quickly in the early stages of a fire, automatically spray water to extinguish the fire, effectively control the spread of the fire, and reduce the losses caused by the fire. At the same time, since chemical plants often contain flammable and explosive materials, the water mist sprayed by fire sprinklers can also cool and dilute flammable gases and toxic fumes, buying valuable time for personnel evacuation and fire rescue.

[0003] Existing technologies, such as the utility model with publication number CN221267004U, disclose a chemical safety fire-fighting device, relating to the field of chemical safety technology. This utility model includes a base with multiple fixing holes at its upper end, a housing fixedly mounted at its lower end, a water inlet on the outer surface of the housing, a rotating disk inside the housing, a first rotating rod fixedly mounted on the inner surface of the rotating disk, a first half-gear fixedly mounted on the outer surface of the first rotating rod, and a second half-gear meshing with the outer surface of the first half-gear. The inner surface of the second half-gear is fixedly... A second rotating rod is fixedly provided, and a limiting plate is fixedly provided on one side of the second half gear. A limiting block is fixedly provided on the outer surface of the limiting plate. This utility model enables the fire-fighting device to adjust the position of the water spray through the first half gear and the second half gear. Furthermore, the fire-fighting device can replace the nozzle through the sliding rod and the sliding groove. This solves the problem that most existing chemical safety fire-fighting devices cannot adjust the position of the water spray when carrying out fire-fighting measures, resulting in the fire-fighting device being unable to accurately extinguish the fire source, thus causing the fire-fighting device to take a long time to extinguish the fire.

[0004] In daily work, it has been found that the above-mentioned chemical safety fire protection devices require manual adjustment of the angle of the fire sprinkler heads. Generally, the fire sprinkler heads are quite high, and manual adjustment makes operation cumbersome and inconvenient. In addition, the fire sprinkler heads are prone to clogging, and after clogging, the sprinkler heads need to be replaced, resulting in waste. This leads to the overall inconvenience of using the existing chemical safety fire protection devices. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing chemical safety fire protection devices, which are inconvenient to use as a whole, and to propose a chemical safety fire protection device.

At the same time, the rotating assembly can control the rotating seat to rotate in the base, and the shielding assembly can shield the nozzle body.

An adjusting motor is fixedly connected to the surface of the rotating seat, and the output end of the adjusting motor is fixedly connected to one end of the transmission screw. By using the above components, when the adjusting motor is turned on, it can drive the transmission screw to rotate. The transmission screw drives the shielding component to slide in the slide rod, thereby controlling the movement of the shielding component. The shielding component can shield the nozzle body or be removed from the nozzle body, thus shielding the nozzle body from dust and reducing clogging.

[0010] Preferably, the shielding member is composed of two rectangular sliding parts and a U-shaped shielding part.

[0011] Preferably, a protective sheet is fixedly connected to the side surface of the shielding member near the nozzle body. The protective sheet is rectangular in shape.

Control arms 48 are rotatably connected to the surface of the fixed shafts 47. Connectors 45 are fixedly connected to the corresponding side of the two control arms 48.

A connector 43 is fixedly connected to one end of the hose 44. The connector 43 is rotatably connected to one end of the water inlet pipe 2. A control motor 49 is provided in the inner wall of the rotating base 41. A gear 410 is fixedly connected to the output end of the control motor 49. The gear 410 meshes with the control arm 48. A rotating assembly 46 is provided between the rotating base 41 and the base 1. A shielding assembly 42 is provided in the inner wall of the rotating base 41.

[0023] In this implementation scheme: when the angle needs to be adjusted, the control motor 49 can be turned on, the control motor 49 can drive the gear 410 to rotate, the gear 410 can drive the control arm 48 to rotate, the control arm 48 can drive the connector 45 and the nozzle body 3 to rotate, thereby adjusting the angle. At the same time, the rotating component 46 can control the rotating seat 41 to rotate in the base 1, and the shielding component 42 can shield the nozzle body 3.

[0024] Specifically, the rotating assembly 46 includes a rotating motor 462, which is fixedly connected to the inner wall of the rotating base 41. A gear 463 is fixedly connected to the output end of the rotating motor 462, and a gear ring 461 is fixedly connected to the surface of the base 1. The gear 463 meshes with the gear ring 461.

[0025] In this implementation scheme: when the rotating seat 41 is controlled to rotate, the rotating motor 462 is turned on. The rotating motor 462 drives the gear 463 to rotate. The gear 463, in conjunction with the gear ring 461, can control the rotating seat 41 to rotate on the base 1, thereby achieving rotation adjustment.

[0026] Specifically, the control arm 48 is composed of a rotating rod and an arc-shaped rack. The gear 410 mainly cooperates with the arc-shaped rack in the control arm 48 to achieve the adjustment operation.

[0027] Specifically, the shielding assembly 42 includes a slide rod 425, which is fixedly connected to the inner wall of the rotating seat 41.

[0032] Working principle: In operation, the adjusting motor 421 is first turned on. The adjusting motor 421 drives the transmission screw 422 to rotate, which in turn causes the shielding member 423 to slide within the slide rod 425. This removes the shielding member 423 and the protective plate 424 from obstructing the nozzle. Subsequently, the water inlet pipe 2 supplies water to the nozzle body 3 through the connector 43 and hose 44, allowing the nozzle body 3 to spray water for fire extinguishing.

The water inlet pipe 2 is rotated. After rotating to a certain angle, the control motor 49 is turned on. The control motor 49 drives the gear 410 to rotate. The gear 410 drives the control arm 48 to rotate on the fixed shaft 47. The two sets of control arms 48 can drive the connecting piece 45 to slide in the arc-shaped hole on the surface of the rotating seat 41, thereby adjusting the nozzle body 3 to spray fire extinguishing at different positions. When it is not needed, the nozzle body 3 is reset, and the adjustment motor 421 is turned on. The adjustment motor 421 drives the transmission screw 422 to rotate. The transmission screw 422 drives the shielding piece 423 to slide in the slide rod 425, controlling the shielding piece 423 and the protective plate 424 to reset, thus shielding and sealing the nozzle body 3.
