An emergency sprinkler

Abstract

The invention relates to an emergency spraying device, which includes a spraying mechanism, the spraying mechanism is provided with a controller, an alarm and a retractable pull rope switch mechanism, and the device is also provided with a multi-channel sound for identifying and detecting calls for help. Probe, the multi-channel sound probe can transmit the sound signal to the controller. When working, the controller will send a signal to the alarm and the retractable pull cord switch mechanism after receiving the signal from the multi-channel sound probe. The alarm sends out a guiding signal so that the user can quickly find the emergency spraying device; the switch mechanism of the retractable pull cord executes an action to lower the pull cord to the ground so that the user can pull the pull cord to start the spraying mechanism to spray water. Compared with the prior art, the present invention is simple in operation, safe in use, convenient for the injured to locate the device in the presence of visual coverings such as thick smoke, and has good man-machine interaction.

Description

technical field [0001] The invention relates to a first aid device, in particular to an emergency spraying device. Background technique [0002] There are many occupational hazards in the workplace, such as toxic chemicals, production dust, corrosive chemicals, harmful physical factors or biological factors, etc. Under certain conditions, occupational harmful factors act directly on the human body, damaging health and causing occupational diseases. Today's safe work requires the installation of necessary emergency sprinklers in toxic and hazardous workplaces. The emergency sprinkler device belongs to the scope of emergency facilities. When the body, face and eyes of the operator are attacked by toxic and corrosive substances such as acid, alkali, organic matter, etc., the sprinkler device can be quickly and effectively washed to make the wounded The degree of injury is reduced to the lightest, so as to ensure the safety of personnel. Whether the washing is timely and thor...

Problems solved by technology

[0005] At present, the function of the emergency shower device is relatively single. The patent CN2517437Y discloses an emergency eyewash device, and the patent CN204233419U discloses an emergency shower eyewash device. However, they are all emergency shower devices with common functions, which cannot cope with or handle some special situations at all. caused the accident

For example, when a disaster occurs (such as heavy smoke and acid mist causing personnel eye injuries and impaired vision), the existing device is only equipped with an eye cleaning function. In this case, it is difficult for personnel to confirm the location of the emergency sprinkler device. In the process of finding the location, the first time of emergency treatment was delayed

Even if the injured find the position of the emergency sprinkler, if they lie down or their hands are injured, they still cannot turn on the sprinkler in time, resulting in missing the best time for emergency rescue, and in the low temperature environment in winter, the water temperature in the water storage tank is too low , not suitable for personal washing
