Description

Technical Field

[0001] The present invention belongs to the technical field of industrial safety protection, and particularly relates to a stable water pressure device applied to an eyewash. Background Art

[0002] During the production process of petroleum and chemical enterprises, there are emergency injury situations where corrosive liquids or toxic substances splash onto the eyes, faces, or clothing of operators. Especially when the eyes are injured, if not rinsed and self-rescued on-site in time, serious consequences will occur. Eyewashes have become essential emergency protection facilities in places where toxic and corrosive substances such as acids and alkalis are contacted. When the eyes of on-site workers come into contact with toxic, harmful, and other corrosive chemical substances, the eyewash can perform emergency rinsing on the eyes to avoid further harm to the human body caused by chemical substances.

[0003] The prior art discloses an application number of 201920520244.0 and a name of a composite eyewash with a pressure-stabilizing nozzle. The above patent solves the problem that due to the large variation in the water supply pressure at the usual operation site, the spraying height of the eyewash also changes accordingly, resulting in an unstable cleaning effect of the eyewash on the eyes, through the pressure-stabilizing nozzle.

[0004] Since the composite eyewash with a pressure-stabilizing nozzle in the above prior art is connected to the water supply at the factory operation site, although the water volume can be adjusted through the pressure-stabilizing nozzle, there are still fluctuations in the water pressure in the pipeline when adjusting the flow rate through the pressure-stabilizing nozzle, and the water body is likely to damage the pipeline. In a state where the domestic water pressure in the factory is extremely volatile, even if the nozzle is replaced, the eyewash is likely to fail.

[0005] In view of the above factors, in the daily use of a dressing plant, to avoid using domestic water, and since the domestic water pressure in the factory is extremely volatile, resulting in the failure of the eyewash, a stable water pressure device applied to the eyewash is provided, which can produce a self-pressurizing effect and has a water storage function, can avoid failure in case of emergency, and is provided with a heat tracing structure to perform heat preservation and anti-freezing treatment on the water inlet pipeline and the drainage pipeline in the use state.

[0011] The inlet end of the water tank is connected to the branch pipeline through a connecting pipe.

[0012] The outlet end of the water tank is connected to the inlet pipeline through a connecting pipe.

[0013] Furthermore, the voltage - stabilizing device is arranged in a wall - mounted structure and is 1 - 2 meters higher than the position where the eyewash is located.

[0014] An exhaust port is provided on the voltage - stabilizing device. The exhaust port is detachably connected to an automatic exhaust valve through a DN25 pipe.

[0015] Furthermore, the buffer device includes a tee pipe connected to the inlet pipeline and a closed - type buffer pipe detachably connected to the tee pipe. A buffer structure is arranged inside the closed - type buffer pipe.

[0016] The buffer structure can move up and down along the closed - type buffer pipe.

[0017] Furthermore, the buffer structure includes a plug in contact with the closed - type buffer pipe. The lower end of the plug is circular - arc - shaped, and two sealing grooves are opened on the plug. Circular rubber rings are installed in the two sealing grooves.

[0018] The circular rubber rings are in contact with the closed - type buffer pipe to form a sealing structure.

[0019] The plug is made of rigid silica gel material, and the height of the plug is 10 - 15 cm.

[0020] Furthermore, the buffer device is arranged at a position on the main pipeline close to the electromagnetic valve.

[0021] Furthermore, an electric tracing structure is provided on both the main pipeline and the branch pipeline.

[0022] The pre-buried underground drainage well connected to the drainage channel through a connecting pipe is provided with an electric tracing structure;

[0023] The electric tracing structure is an electric tracing band, and the electric tracing band is wound around the pipe wall of the pre-buried underground drainage well in a spiral manner;

[0024] The electric tracing structure is connected to a power supply junction box, the power supply junction box is connected to a temperature control box placed on the bottom surface through a power cable, and the temperature control box is set with a single-chip microcomputer or a PLC structure.

[0027] A usage method of a stable water pressure device applied to an eyewash includes the following steps;

[0028] A water inlet pipe is connected to the eyewash, the water inlet pipe includes a main trunk pipeline and a branch trunk pipeline arranged in parallel, and a voltage stabilizing device is arranged on the branch trunk pipeline;

[0029] When the water pressure of the main trunk pipeline tends to be insufficient, the main trunk pipeline is cut off through an electromagnetic valve. At this time, the branch trunk pipeline remains connected to the eyewash. The water inlet pipe is connected at a position 10 cm from the top in the horizontal direction of the water tank, and the lower part of the water tank is provided with an opening to connect to the eyewash. When the pipeline pressure is sufficient, the water tank is automatically filled with water and the top discharges air. When the pipeline pressure is insufficient, when using the eyewash, the siphon phenomenon in the water tank can be utilized to increase the pressure in the pipeline. When a water supply interruption occurs, the water stored in the water tank is sufficient for the emergency use of the eyewash;

[0030] Wherein, electric tracing structures are arranged on the main trunk pipeline and the branch trunk pipeline, and the pre-buried underground drainage well connected to the drainage channel through a connecting pipe is provided with an electric tracing structure;

[0031] The electric tracing structure set can provide a heat preservation effect in winter and prevent the water temperature in the emergency shower and eyewash from being too high. By setting a temperature sensor node to collect the temperature, when the sensed water temperature exceeds 30 degrees, the water stored in the device will be automatically discharged, and cold water sources will be replenished until the water temperature meets the requirements.

[0032] Compared with the prior art, the beneficial effects of the present invention:

[0033] The present invention adopts a wall-mounted structure to set up a water tank, which is installed 1.5 meters above the eyewash. A 25-mm hole is opened on the water tank, and an automatic exhaust valve is connected with a DN25 pipe. The water inlet pipe is connected 10 cm from the top in the horizontal direction of the water tank. The lower part of the water tank is connected to the eyewash. When the pipeline pressure is sufficient, the water tank is automatically filled with water and the air is exhausted at the top. When the pipeline pressure is insufficient, when using the eyewash, the siphon phenomenon in the water tank can be utilized to increase the pressure in the pipeline. When a water outage occurs, the water stored in the water tank is sufficient for the emergency use of the eyewash.

[0034] In order to avoid pipeline oscillation formed after closing the valve in the use state, the present invention sets a buffer structure. Among them, the circular rubber ring contacts with the closed buffer pipe to form a sealing structure. The plug is made of hard silicone material. The height of the plug is 10-15 cm. With the above structure, a sealing structure is formed by the contact between the circular rubber ring and the closed buffer pipe. The pressure in the pipeline is balanced by the movement of the buffer structure in the pipeline of the closed buffer pipe, effectively eliminating irregular oscillation.

[0035] The present invention is provided with a tracing heating structure, which can perform heat preservation and anti-freezing treatment on the water inlet pipe and the drain pipe in the use state.

[0036] The present invention is provided with a thermostat and a temperature sensor node, which can monitor the pipeline temperature in real time for easy adjustment through the tracing heating structure.
