Description
Technical Field
The invention relates to a safety appliance for a laboratory, in particular to an emergency showering device for the laboratory.
Background
In chemical laboratories, laboratory personnel are faced with safety issues, for example, some toxic and harmful substances and other corrosive chemicals may cause skin or eye damage once they contact the skin of the human body or splash into the eyes, and most of these conditions can be alleviated by rinsing with a large amount of clear water to prevent the toxic and harmful substances from remaining in the skin or eyes and causing further damage.
The laboratory emergency showering device is a device which is arranged in a laboratory and is used for rapidly spraying a large amount of clean water, and generally comprises a spray head used for showering a body and an eye washer used for washing eyes.
General emergent device of drenching in laboratory need be through pulling down the pull rod or twist the handle and open the valve to make shower nozzle and eye washer spray water, however when the laboratory staff actually receives the injury of poisonous and harmful substance, can produce nervous and urgent mood, especially when the eye receives the harm, can't see the position of handle and pull rod clearly for a moment, lead to can't opening the valve at once, lead to the time of washing by water delayed, can't effectively guarantee laboratory staff's safety.
For example, the disclosure of the chinese patent document "top spray drainage collection device for vertical emergency eye washer" is published with CN203874083U, and includes an eye washer, a top spray shower head, a vertical pipe, a horizontal pipe in fluid communication with the vertical pipe, a top spray control valve for controlling the opening and closing of the top spray shower head, and an eye washer control valve for controlling the opening and closing of the eye washer, wherein the vertical pipe is provided with a water inlet and a water outlet.
Disclosure of Invention
The invention provides an emergency showering device for a laboratory, which aims to solve the problem that in the prior art, an emergency showering device is not convenient to open in an emergency, so that experimenters cannot flush water at the first time after being injured, and the experimenters can be injured more, and can open a valve quickly in the emergency, so that the experimenters flush water at the first time, and the injury caused by toxic and harmful substances is reduced as much as possible.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention relates to a laboratory emergency showering device, which comprises a base, a spray head, an eye washer and a water pipe, a spray head control valve and an eye washer control valve are arranged on the water pipe, the spray head control valve comprises a spray head pull rod for controlling the spray head to open and close, the eyewash equipment control valve comprises a handle for controlling the opening and closing of the eyewash equipment, the water pipe comprises a normal open pipeline and an emergency pipeline, the normally open pipeline and the emergency pipeline are both connected with the spray head and the eye washer, the spray head control valve and the eye washer control valve are arranged on the normally open pipeline, hand railings are arranged on two sides of the base, the hand railings on the two sides are connected through a railing connecting rod, the base is provided with a pedal, the pedal is rotationally connected with the base, the handrail is connected with the pedal through a pedal spring, an emergency valve is arranged on the emergency pipeline, and the emergency valve is connected with the pedal through a connecting piece.
The emergency pipeline and the normally open pipeline can both supply water to the spray head and the eye washer, and the difference is that the normally open pipeline is controlled by the handle and the spray head pull rod, and the emergency pipeline is controlled by the pedal; the device can be fixedly prevented from being arranged at a certain position of a laboratory, and after the device reminds an experimenter of the position of the device, once the experimenter is injured by toxic and harmful substances, the experimenter only needs to run below the spray head of the device immediately to step on the pedal, and the pedal rotates and drives the pedal spring to open the emergency valve, so that water flow is sprayed out immediately by avoiding the spray head control valve and the eyewash control valve, and the injured person can flush water at the first time; in order to avoid that when a person lifts a foot on the pedal, the pedal can be stably kept in a pressed state, the triggering force of the pedal is not too large, so that the pedal is easily touched by mistake, for example, when a pedal spring is aged, the pedal falls under the action of gravity, so that an emergency valve is opened, and a sprayer and an eye washer continuously spray water, so that a large amount of clear water is wasted; therefore, when the laboratory does not carry out the experiment related to the toxic and harmful substances within a period of time, or the emergency valve can not work normally due to the aging of a pedal spring and other reasons, the water can be supplied to the normally open pipeline only, but not to the emergency pipeline, so that the condition that a large amount of clear water is wasted is avoided; the hand rails can keep the body of an experimenter stable when the experimenter fills water, and the experimenter is prevented from slipping due to water on the pedals.
