Description

Technical Field

[0001] This utility model relates to the technical field of industrial emergency rescue facilities, specifically to a low-temperature resistant emergency shower facility. Background Technology

[0002] In industrial hazardous work areas (not limited to hazardous chemical production sites), such as the truck filling area of ​​a sulfuric acid plant, accidents such as sulfuric acid leaks and spills may occur during actual operations, seriously affecting personnel safety. In northern regions, winter outdoor temperatures can reach below -20 degrees Celsius. The frigid winters cause eyewash station pipes to freeze and crack, rendering them unusable. Repairing pipes and eyewash stations requires significant manpower and resources and is not applicable for emergency rescue. Therefore, improving the safety of industrial hazardous work areas and reducing the frequency of pipe repairs have become urgent problems that need to be solved.

[0003] In existing technologies, electrically heated eyewash stations are commonly used to address the problem of frozen pipes at low temperatures. For example, Chinese patent CN215536482U discloses an electrically heated eyewash station, which includes a flame-retardant shell, an electric heating tape, a temperature control box, an inlet pipe, a first inlet branch pipe, a second inlet branch pipe, an outlet pipe, a sprayer, an eyewash station, a pull handle switch, and a wrench switch. The electric heating tape heats the inlet pipe to prevent the water inside the pipe from freezing. However, the heating of the water inside the pipe in this device is uncontrolled, which may lead to accidents caused by excessively high heating temperatures and secondary injuries. Therefore, there is a need to develop a low-temperature emergency shower facility with controllable output water temperature and intelligent automation. Utility Model Content

[0004] To address the problems of existing technologies, this utility model proposes a low-temperature resistant emergency showering facility, the specific solution of which is as follows:

[0005] A low-temperature resistant emergency shower facility includes: a steel frame, a water tank, a showering device, a water pump, solar lighting, and a power supply system (with a 24V power supply installed in a control box). The water tank is connected to a tap water pipe and located above the steel frame. The water tank is covered with thermal insulation foam board and contains a heating resistor, a first temperature sensor, and a level gauge. The showering device is connected to the water tank via the water pump and is located inside the steel frame. A second temperature sensor and a sound-activated solenoid valve are installed at the outlet of the showering device. A second temperature sensor is also installed on the tap water pipe. Explosion-proof heating tape is wrapped around the water tank, the showering device pipe, and the tap water pipe. An infrared sensor is installed on the steel frame. The explosion-proof heating tape, water pump, level gauge, first temperature sensor, second temperature sensor, sound-activated solenoid valve, infrared sensor, and heating resistor are electrically connected to the power supply system, which includes multiple control contactors.

[0006] Furthermore, the rinsing device is an eyewash station.

[0007] Furthermore, three of the four sides of the steel frame are surrounded by aluminum composite panels and / or tempered vacuum glass.

[0008] Furthermore, the power supply system also includes a transformer, an uninterruptible power supply, and a leakage current protection device. The power supply system is housed in a control box, which is mounted on a steel frame.

[0009] Furthermore, a solenoid valve is installed at the connection between the water tank and the tap water pipe, and the level gauge and the solenoid valve are electrically connected via a control contactor.

[0010] Furthermore, a temperature digital display is installed on the back wall of the steel frame.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) The low-temperature emergency shower facility of this utility model monitors the temperature of the water in the water tank and the outlet of the shower equipment, turns on the heating resistor to heat the water in the water tank, turns on the explosion-proof heat tracing cable to heat the water tank and the pipe, and stops heating when the temperature is too high, so as to maintain the water outlet temperature of the eyewash station at 35℃-40℃, so as not to cause secondary damage due to the water outlet being too cold or too hot, and to keep the eyewash station available for emergency use at temperatures below -20℃, solving the problem of the outdoor eyewash station facilities and pipes freezing and cracking in winter in hazardous chemical enterprises, ensuring the compliance and legality of outdoor work sites in winter, reducing the frequency and cost of maintenance of water supply pipes and eyewash stations in winter, and significantly reducing the workload and intensity of maintenance staff.

[0013] (2) Compared with the circulating water eyewash station, the emergency shower room with steel frame is easier to operate in the winter in the north, reduces emergency time, and ensures that workers can rinse for more than 15 minutes in case of an accident in winter. At the same time, the steel frame is surrounded by aluminum-plastic panels or tempered vacuum glass, which plays a certain role in heat preservation. In addition, the water tank is wrapped with heat-insulating foam board to further enhance the heat preservation effect of the water tank, reduce heat loss, and maintain the stability of water temperature.

[0014] (3) Use uninterruptible power supply to ensure heating and insulation during extreme winter weather; install solar lighting on the steel frame to ensure that the emergency shower facilities have good lighting conditions at all times, so that operators can operate in an emergency; at the same time, install a voice-controlled solenoid valve in parallel with the manual valve at the water outlet of the shower equipment, and cooperate with the infrared sensor installed on the steel frame. When someone enters the steel frame, the shower equipment can be turned on by voice control, so that the shower equipment can be used in a timely and effective manner when the eyes are injured; at the same time, a level gauge is installed in the water tank. When the level is too low, the solenoid valve is opened in time by the controller to replenish water from the tap water pipe, so as to avoid the equipment being unusable due to insufficient water in the water tank.

[0015] This invention can effectively construct an intelligent and automated low-temperature resistant emergency shower facility, enabling it to operate normally in the cold winter environment of northern regions. It solves problems such as freezing and cracking of pipes in eyewash facilities in hazardous industrial work areas such as sulfuric acid plant vehicle filling areas, fully protecting the personal safety of workers, reducing maintenance costs and the workload of employees, and improving the safety and compliance of production operations.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0026] In one embodiment, a low-temperature emergency shower facility includes: a steel frame 1, a water tank 3, a shower device 7, a water pump 20, solar lighting 12, and a power supply system. The shower device 7 is specifically an eyewash station. The connecting pipes of the eyewash station should be made of corrosion-resistant materials, and the connections should be tight and leak-free. The nozzles of the eyewash station should be cleaned and maintained regularly to ensure unobstructed flow and a stable water flow for rinsing. Three sides of the steel frame 1 are surrounded by aluminum composite panels 2, and one side is a tempered vacuum glass door 5. The steel frame is selected as the basic support structure for the entire low-temperature emergency shower facility to ensure sufficient strength and stability to withstand the various components of the facility and potential external forces, such as wind and snow pressure under severe weather conditions. The middle of the steel frame is filled with aluminum composite panels 2 and tempered vacuum glass, and connected with high-quality sealant to form a relatively closed and insulated outer shell. Tempered vacuum glass not only has good thermal insulation properties, reducing the exchange of internal heat with cold outside air, but its material also has a certain degree of corrosion resistance, making it suitable for places with corrosive environments such as sulfuric acid plants.

[0027] Water tank 3 is connected to the tap water pipe and located above the steel frame 1. A solenoid valve 8 is installed at the connection point between water tank 3 and the tap water pipe. Water tank 3 is covered with insulating foam board 4. Inside water tank 3 are a heating resistor 17, a first temperature sensor 10, and a level gauge 9. The level gauge 9 is electrically connected to the solenoid valve 8 via a control contactor 11. Water tank 3 is made of stainless steel, and its capacity ensures a continuous water supply for at least 15 minutes in emergency situations for the eyewash station. The stainless steel material effectively prevents damage from corrosive substances such as sulfuric acid, ensuring the lifespan of the water tank and the safety of the water quality. The insulating foam board further enhances the insulation effect of the water tank, reduces heat loss, and maintains a stable water temperature. The insulating foam board should be tightly fitted to the surface of the water tank and secured with waterproof tape or other materials to prevent moisture from entering the foam board and affecting its insulation performance.

[0028] The rinsing device 7 is connected to the water tank 3 via the water pump 20. The rinsing device 7 is located inside the steel frame 1. A second temperature sensor 19 and a sound-controlled solenoid valve 21 are installed at the outlet of the rinsing device 7. Explosion-proof heating tape 6 is wrapped around the outside of the water tank 3, the outside of the pipes of the rinsing device 7, and the outside of the tap water pipe. An infrared sensor 22 is also installed on the steel frame 1. The explosion-proof heating tape 6, the water pump 20, the level gauge 9, the first temperature sensor 10, the second temperature sensor 19, the sound-controlled solenoid valve 21, the infrared sensor 22, and the heating resistor 17 are electrically connected to the power supply system. The power supply system includes multiple control contactors 11, a transformer 13, an uninterruptible power supply 14, and a leakage current protector 15. The power supply system is located in the control box 18, which is located on the steel frame 1.

[0029] Explosion-proof heating cable 6 is wrapped around the outside of the stainless steel water tank and the pipes connecting to the eyewash station. The selection of the explosion-proof heating cable should be determined based on factors such as the actual pipe length, water tank volume, and required heating power. The heating cable should be wrapped evenly and tightly to ensure effective heating of the water in the tank and pipes, preventing freezing. The control contactor 11 includes contact controllers 1, 2, and 3. The power supply to the heating cables outside the water tank, eyewash station pipes, and tap water pipes is controlled by contact controller 1. The two second temperature sensors 19 at the eyewash station outlet and the tap water pipe are set to a temperature range of 1-10 degrees Celsius. When either second temperature sensor 19 is below 1 degree Celsius, it transmits a signal to contact controller 1 to turn on the power to the explosion-proof heating cable 6, controlling the heating cable 6 to start heating. When both second temperature sensors are above 10 degrees Celsius, they transmit a signal to contact controller 1 to turn off the power and stop heating, preventing freezing and damage to the pipes. The heating resistor inside the water tank is controlled by contactor controller No. 2. The first temperature sensor inside the water tank is set to a temperature range of 35-40 degrees Celsius. When the temperature is below 35 degrees Celsius, a signal is transmitted to contactor controller No. 2 to turn on the heating resistor switch. When the temperature is above 40 degrees Celsius, a signal is transmitted to contactor controller No. 2 to disconnect the power and stop heating. This achieves automatic heating control within the 35-40 degree Celsius range, thus ensuring precise water temperature control and maintaining a constant water temperature from the eyewash station within a suitable range, preventing secondary injuries caused by excessively cold or hot water. When infrared sensor 22 detects someone entering the steel frame area and the sound triggers the sound-activated solenoid valve 21, the shower equipment, i.e., the eyewash station, opens immediately without manual intervention, saving rescue time. A manual switch is also provided for simultaneous use. Additionally, a level gauge 9 is installed inside the stainless steel water tank 3. The level gauge uses a high-precision sensor to monitor the water level in the tank in real time. The signal from the level gauge is transmitted to contact controller No. 3 in the control box. When the water level is lower than the set minimum water level, the control box triggers the solenoid valve 8 at the connection between water tank 3 and the tap water pipe to open, allowing water from the tap water pipe to flow into water tank 3 for replenishment. When the water level reaches the set maximum water level, the solenoid valve 8 is triggered to close, ensuring that there is always enough water in the water tank for emergency showering, thus guaranteeing the reliability and availability of the emergency showering facility.

[0030] In addition, a solar lighting system is installed, with solar panels mounted on or near the facility in a sunny location. A controller converts solar energy into electricity, which is stored in batteries to power the lighting inside the facility. During the day when there is sufficient sunlight, the solar lighting system automatically charges and powers the lights. At night or when there is insufficient sunlight, the battery power sustains the lighting system, ensuring good lighting conditions for the emergency shower facility at all times, facilitating operation by personnel in emergencies.

[0031] The power supply system is housed in control box 18, which is mounted on steel frame 1. A transformer 13 is installed in the power supply system to convert the external 220V voltage to a safe 24V voltage, ensuring the normal operation of the equipment and the safety of personnel. The transformer should be selected with appropriate capacity and transformation ratio to meet the power requirements of equipment such as explosion-proof heating cables, stainless steel water pumps, level gauges, and control boxes, and should have good overload protection and voltage stabilization performance to prevent voltage fluctuations from damaging the equipment. An uninterruptible power supply (UPS) 14 works in conjunction with a residual current device (RCD) 15. The UPS is connected to the main power supply circuits, such as the control circuits of explosion-proof heating cables and eyewash stations, ensuring that in the event of a sudden external power outage, the UPS can quickly switch power to maintain the emergency operation of heating, insulation, and eyewash stations, ensuring the normal operation of the facilities under extreme winter weather conditions. The RCD is installed on the main power line and each branch circuit, monitoring the leakage current in real time. In the event of a leakage fault, it can quickly cut off the power supply to protect the safety of personnel and equipment. The digital display is used in conjunction with the temperature sensor. The temperature digital display 16 is installed on the control box panel and can intuitively display the water temperature in the water tank and the water temperature in the pipes, so that the operator can understand the water temperature status at any time.

[0032] The foregoing description describes some exemplary embodiments of this utility model. It is understood that the above embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model. The features in these embodiments can be recombine in a suitable manner, and the resulting solutions are still within the scope of protection claimed by this utility model.
