Description

Technical Field

[0001] This utility model relates to the field of chemical decontamination equipment technology, and in particular to an emergency safety decontamination water tank and its control system. Background Technology

[0002] Decontamination pools are an important part of safety facilities in chemical laboratories. They are mainly used to deal with chemical leaks, splashes, or other emergencies to ensure the safety of laboratory personnel. They can immediately rinse away chemicals on the skin or eyes, clean laboratory equipment, and reduce the harm of chemicals to the body.

[0003] A search of existing technologies revealed that Chinese patent CN216365908U discloses an energy-storing, water-filled emergency eyewash station for chemical engineering laboratories, suitable for situations requiring emergency eyewashing, such as in temporary experimental environments with low water pressure or no water or electricity. However, it is worth considering that, on the one hand, the eyewash nozzle of this device is in a fixed position, lacking user-friendliness; on the other hand, the control system of this eyewash device is decentralized, unable to meet personalized needs, and has certain limitations.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an emergency safety decontamination pool and its control system to solve the problem that existing chemical cleaning equipment and control systems cannot meet personalized needs.

[0006] Based on the above objectives, this utility model provides an emergency safety decontamination tank and its control system, including a base cabinet. The base cabinet includes four columns and a ring beam set on the top of the columns. A base plate is set at the bottom of the base cabinet. A washing and care water tank is attached to the top left side of the ring beam. A lifting component is set at the bottom of the washing and care water tank. A control panel is set in the middle of the top of the ring beam. An ultrasonic water tank and an emergency medicine box are set on the top right side of the ring beam. A flip-up cover is set on the top of the ultrasonic water tank. A protective shell is set between the columns around the base cabinet. A hot water tank is set adjacent to each other inside the base cabinet. An electrical distribution box and a storage cabinet are set in sequence outside the hot water tank. A pipe assembly is set on the top of the hot water tank. The pipe assembly connects the control panel, the washing and care water tank and the ultrasonic water tank.

[0007] Through the above technical solutions, the present invention integrates a washing and disinfection water tank into a closed cabinet on all four sides, which can be placed in a chemical laboratory near a water source. It provides hot water through a hot water tank, water supply and sewage discharge through a pipe assembly, washing and care of the face, eyes and nose of laboratory personnel through a washing and care water tank, and cleaning of laboratory equipment through an ultrasonic water tank. It also integrates storage functions.

[0008] Furthermore, the washing and care sink includes a dual-nozzle eyewash device, a handheld nasal rinser, and a faucet. The lifting assembly includes four lifting cylinders fixedly connected to the base plate. The output end of the lifting cylinder is a piston rod. The ends of the four piston rods are fixedly connected to the four corners of the bottom of the washing and care sink. A cross link is fixedly connected between the four piston rods, and a hole is opened in the center of the cross link.

[0009] Through the above technical solutions, the washing and care sink can provide eye washing, nose washing and hand and face cleaning functions. The washing and care sink is raised and lowered by four sets of cylinders to ensure that the eye washing device is more in line with the face height of different users in different standing postures. The cross linkage ensures that the four sets of cylinders can raise and lower smoothly and synchronously without tilting or overturning.

[0010] Furthermore, an electric heater is installed through the side of the hot water tank. The electric heater is connected to the flange on the side of the hot water tank and penetrates the protective shell. The hot water tank is heated by the electric heater.

[0011] Furthermore, the piping assembly includes a cold water inlet and a hot water inlet running through the back of the protective housing. The hot water inlet leads to a hot water tank, and a booster pump is placed on top of the hot water tank. The output end of the booster pump is connected to a hot water pipe. The cold water inlet connects to a cold water pipe. The hot water pipe and the cold water pipe converge below the control panel, and a mixing valve is installed at the convergence point. A ball valve is installed at the outlet of the mixing valve, and the outlet of the ball valve branches the flow to the washing and care sink and the ultrasonic water tank. A corrugated inlet pipe is installed below the washing and care sink. A four-way water tank inlet pipe is installed near the end of the corrugated inlet pipe near the washing and care sink. The three outlet pipes of the four-way water tank inlet pipe are respectively connected to a dual-nozzle eyewash device, a handheld nasal irrigator, and a faucet. A drain pipe is installed in the center of the bottom of the washing and care sink. A drain corrugated pipe is installed near the washing and care sink. A drain pipe is installed at the bottom of the ultrasonic water tank.

[0012] Through the above technical solution, the hot water tank is replenished with water through the inlet, and the hot water is pumped out by the booster pump. The hot and cold water are mixed at the mixing valve, and the mixed warm water is distributed to the washing and care sink and the ultrasonic water tank through the ball valve. Among them, the water flow to the washing and care sink is distributed to the dual-nozzle eyewash device, handheld shower nasal irrigator and faucet. A corrugated pipe is installed before the distribution pipe to compensate for the expansion and contraction of the pipe during the raising and lowering of the washing and care sink. The wastewater from the washing and care sink and the ultrasonic water tank is discharged through the sewage pipe, and the drainage corrugated pipe is used to compensate for the expansion and contraction of the pipe during the raising and lowering of the washing and care sink.

[0013] Furthermore, a distribution box cover is provided on the side of the protective shell at the corresponding position on the upper part of the distribution box. The distribution box cover is bolted to the distribution box. A movable cabinet door for the storage cabinet is opened on the side of the protective shell near the storage cabinet.

[0014] Through the above technical solutions, the power distribution box cover controls the power input of the entire device, and the movable cabinet door of the storage cabinet makes it convenient to take out and put away miscellaneous items.

[0015] This utility model also includes a control system for the above-mentioned washing and disinfection water tank, including a control panel; a water tank lifting control module, which controls the extension and retraction of the piston rod of the lifting cylinder to realize the lifting and lowering of the washing and care water tank; and an ultrasonic water tank cleaning module, which is used to control the start and stop of the ultrasonic water tank.

[0016] Furthermore, the control panel includes an LCD touch screen, a temperature control knob, and a water pressure control knob. Several conductive electrodes are integrated on the surface of the LCD touch screen, and functional text labels are made near the conductive electrodes. The temperature control knob is fixedly connected to the mixing valve core, and the water pressure control knob is fixedly connected to the ball valve core.

[0017] Through the above technical solutions, the LCD touch screen improves the user's control experience. The conductive electrodes, as human touch points, can respond to different control circuits. Operators can operate according to the text markings near the electrodes. The temperature control knob is used to adjust the water temperature, and the water pressure control knob is used to adjust the water pressure.

[0018] Furthermore, the water tank lifting control module includes a three-position five-way solenoid valve SV and a lifting control circuit. The three-position five-way solenoid valve SV includes two solenoid coils EV1 and EV2, two output ports A and B, two exhaust ports R and S, and a pressure inlet P. Output ports A and B are respectively connected to the rodless end and the rod end of the lifting cylinder. Each of the two solenoid coils EV1 and EV2 has an independent lifting control circuit. The lifting control circuit includes a rectifier circuit and a lifting touch response circuit.

[0034] 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 specific embodiments.

[0035] This embodiment proposes an emergency safety decontamination pool, such as... Figure 1 As shown, the device is enclosed by a protective shell 7. From left to right, the top of the device is equipped with a washing and care water tank 2, a control panel 4, an ultrasonic water tank 5, and an emergency medicine box 6. The control panel 4 is equipped with an LCD touch screen 401, a temperature control knob 402, and a water pressure control knob 403. The top of the ultrasonic water tank 5 is equipped with a flip-up cover 501. The front of the protective shell 7 is equipped with a power distribution box cover 701 and a storage cabinet door 702.

[0036] like Figure 2 As shown, the base cabinet 1 includes four uprights 101 and a ring beam 102. The front of the interior of the base cabinet 1 is equipped with a storage cabinet 11 and an electrical distribution box 10, and the bottom of the base cabinet 1 is equipped with a base plate 103.

[0037] like Figure 3 and Figure 5 As shown, a hot water tank 801 is installed inside the back of the cabinet 1. An electric heater 8011 is connected to the side of the hot water tank 801. The hot water tank 801 supplies water to the washing and care sink 2 and the ultrasonic water tank 5 through a pipe assembly.

[0038] like Figure 4As shown, the washing and care sink 2 is equipped with a dual-nozzle eyewash device 201, a handheld nasal rinser 202, and a faucet 203 to meet the needs of washing eyes, rinsing nose, and washing hands. Four lifting cylinders 301 are installed at the four corners of the bottom of the washing and care sink 2. The piston rods 3011 of the four lifting cylinders 301 are fixedly connected by X-shaped cross rods 302 to ensure the consistency of the lifting process and prevent the washing and care sink 2 from tipping over.

[0039] like Figure 5 As shown, the cold water inlet 901 connects to the cold water pipe 905, and the hot water inlet 902 connects to the hot water tank 801. A booster pump 903 is installed on the top of the hot water tank 801. The hot water pipe 904 and the cold water pipe 905, which are connected to the outlet of the booster pump 903, converge at the mixing valve 906. The temperature control knob 402 is fixedly connected to the valve core of the mixing valve 906. A ball valve 907 is installed at the outlet of the mixing valve 906. The ball valve 907 is controlled by the water pressure control knob 403. The water from the outlet of the ball valve 907 is diverted to the washing and care water tank 2 and the ultrasonic water pool 5. The end of the water supply pipe near the washing and care water tank 2 is equipped with... A corrugated inlet pipe 908 is installed to compensate for the pipe expansion and contraction caused by the raising and lowering of the washing and care sink 2. The end of the corrugated inlet pipe 908 is split into a four-way water inlet pipe 909 and directed to the dual-nozzle eyewash device 201, the handheld shower nasal irrigator 202, and the faucet 203. Thus, an adjustable temperature and pressure water supply pipe is formed. The sewage pipe includes a sewage pipe 910 for the washing and care sink 2 and a sewage pipe 912 for the ultrasonic water tank 5. A corrugated drain pipe 911 is installed near the washing and care sink 2 on the sewage pipe 910 to compensate for the pipe expansion and contraction caused by the raising and lowering of the washing and care sink 2.

[0040] This embodiment of the utility model also provides a control system integrated into the control panel 4, including a temperature control knob 402 for controlling water temperature, a water pressure control knob 403 for controlling water pressure, and a control system based on an LCD touch screen 401, which can adjust the height of the water tank and control the opening and closing of the ultrasonic water tank according to the user's individual needs. Figure 6 As shown, the sink lifting control module contains two independent control loops, used to control the on / off state of the two coils EV1 and EV2 on the left and right sides of the three-position five-way solenoid valve SV, thereby controlling the airflow circuit of the three-position five-way solenoid valve SV to adjust the lifting and stopping state of the washing sink 2. Figure 6The control circuit for raising the water tank on the left side includes a rectifier circuit and a rise touch response circuit. The rectifier circuit uses a bridge rectifier circuit to convert 220V AC power into DC power. This DC power, approximately 12V, is then supplied to the rise touch response circuit via a voltage divider resistor R1 across a filter capacitor C11. The rise touch electrode TP1, protection resistor Rs1, and touch electrode response transistor VT1 are connected in series. The emitter of touch electrode response transistor VT1 is electrically connected to the gate of micro-trigger unidirectional thyristor VS1, providing it with trigger current. The control circuit for lowering the water tank on the right side is similar and will not be described in detail.

[0041] Working principle: When the user presses and holds the rising touch electrode TP1, the touch electrode response transistor VT1 is turned on, and the gate of the micro-trigger unidirectional thyristor VS1 is also turned on due to the trigger current flowing in. The connected electromagnetic coil EV1 is then energized, the solenoid valve core moves to the left, the PAS airflow circuit is activated, the air pressure at the rodless end of the lifting cylinder 301 rises, the piston rod 3011 is pushed out, and the washing and conditioning tank 2 rises. Conversely, when the user presses and holds the falling touch electrode TP2, the washing and conditioning tank 2 falls. When the hand is removed from the rising touch electrode TP1, the touch electrode response transistor VT1 is turned off, the gate of the micro-trigger unidirectional thyristor VS1 is also turned off due to the lack of trigger current flowing in, the electromagnetic coil EV1 is de-energized, the solenoid valve core retracts under the action of the spring, the pressure inlet P is closed, the piston rod 3011 returns to its current position, and the washing and conditioning tank 2 remains stationary. In summary, by pressing and holding the corresponding conductive electrode on the LCD touch screen 401, the washing and conditioning tank 2 can be raised, lowered, or stationary.

[0042] like Figure 7As shown, the ultrasonic water tank cleaning module includes an ultrasonic generator (USG) and an ultrasonic control circuit. The ultrasonic generator (USG) generates a high-frequency electrical signal, which is then converted into ultrasonic waves by a transducer for disinfection. The ultrasonic control circuit controls the on / off state of the relay coil inside the ultrasonic generator (USG). The ultrasonic control circuit includes a rectifier circuit and an ultrasonic touch response circuit. The rectifier circuit uses a bridge rectifier circuit to convert 220V AC power into DC power, which is then divided by a voltage divider resistor (R2) and a filter capacitor (C13) to form a DC voltage of approximately 12V, which is supplied to the ultrasonic touch response circuit. In the ultrasonic water tank operation mode, the touch electrode TP3, the protective resistor Rs3, and the touch electrode response transistor VT3 are connected in series. The emitter of the touch electrode response transistor VT3 is electrically connected to the positive terminal of the energy storage capacitor C21 to charge it. The positive terminal of the energy storage capacitor C21 is connected to the gate of the micro-trigger unidirectional thyristor VS3 via the bias resistor Rb1 to provide trigger current for the touch electrode response transistor VT3 after it is turned off. In the ultrasonic water tank shutdown mode, the touch electrode TP4, the protective resistor Rs4, and the touch electrode response transistor VT4 are connected in series. The touch electrode response transistor VT4 is connected across the two ends of the energy storage capacitor C21 to provide a discharge path.

[0043] Working principle: When the user touches the ultrasonic water tank's operating touch electrode TP3, the touch electrode's response transistor VT3 turns on, the energy storage capacitor C21 charges, and the micro-trigger unidirectional thyristor VS3 also conducts due to the trigger current flowing into its gate. This energizes the internal relay coil of the connected ultrasonic generator USG, putting both the ultrasonic generator USG and the ultrasonic water tank 5 into operation. When the user removes their hand from the ultrasonic water tank's operating touch electrode TP3, the touch electrode's response transistor VT3 turns off, the energy storage capacitor C21 discharges, and the micro-trigger unidirectional thyristor discharges via the bias resistor Rb1. The gate of VS3 continues to provide trigger current, ensuring that the micro-trigger unidirectional thyristor VS3 remains on. Therefore, even after the hand leaves the ultrasonic water tank operating touch electrode TP3, the ultrasonic water tank 5 can continue to operate. When the hand touches the ultrasonic water tank operating touch electrode TP3, the touch electrode response transistor VT4 turns on, and the energy storage capacitor C21 discharges rapidly through the touch electrode response transistor VT4. The gate of the micro-trigger unidirectional thyristor VS3 loses trigger current, and VS3 turns off. The ultrasonic generator USG, along with the ultrasonic water tank 5, is then de-energized and enters a non-operating state. In summary, the operator starts the ultrasonic water tank 5 by pressing the ultrasonic water tank operating touch electrode TP3, and the ultrasonic water tank 5 continues to operate after releasing it. The ultrasonic water tank 5 is turned off by pressing the ultrasonic water tank operating touch electrode TP3.
