The bottom of the bottom frame is attached with a foam material (or a 1CM sponge adhesive tape) and is placed on the ground; or the bottom flexible body (1-2-2) of the flexible cover body is made of cloth strip materials, wraps the bottom frame and is in contact with the ground; the bottom frame is connected with the ground in a seamless mode through the cloth strips.
The space body of the flexible cover body is designed to be a three-dimensional cover body surrounded by the top surface and the circumference. The top surface of the flexible enclosure is served by an air box. For example and without limitation, the air box and the hard frame formed by the bracket are covered outside in use and are sleeved from top to bottom; when not in use, the utility model is picked up from bottom to top. Or a plurality of surface bodies of the three-dimensional space of the flexible cover body are combined through the longitudinal movable connecting device (1-2-1) after being fixed on the bracket.
The moving wheel system and the lifting system at the bottom:
the portable detachable air sterilizer disclosed by the invention is matched with the clean cover to move, the wheels (6-1) are arranged at the bottom of the bracket and the wheels (6-2) are also arranged at the bottom of the sterilization platform, so that the portable detachable air sterilizer is convenient and suitable for the requirement of emergency moving in hospitals or temporary medical bases when emergency needs are needed. As shown in fig. 10 and 11.
Meanwhile, a bridging device (1-5) is arranged between the main bracket (1-3) and the bottom frame (1-4) for convenient use and disassembly. When moving, the bottom frame is lifted and pulled away from the ground through the bridging device, and is fixed on the main brackets (1-3) through the bridging device, so that the wheels are pushed to move to a new position and be used in a department. After reaching the position, the bottom frame is lowered to the ground through the bridging device, and meanwhile, the wheels (6-2) are locked in place through the bridging device and limited on the main bracket, so that stability and reliability are guaranteed in use.
The bridge device (1-5) is structurally realized as follows: the device comprises two connecting rod pieces (1-5-1) and a screw nut (1-5-2), wherein vertical strip holes are prefabricated in the two connecting rod pieces, one connecting rod piece is used for connecting a main support (1-3), the other connecting rod piece is connected with a bottom frame (1-4), and the screw nut penetrates through the two vertical strip holes and is screwed down to be used for temporary fixing or limiting.
The bottom frame (1-4) is structurally realized as follows: integrally casting; or comprises long strips (1-4-1) and corner strips (1-4-2), which are overlapped through connecting strips (1-4-3). If necessary, the base frame (1-4) structure may be supplemented with weights (not shown) to be pressed at the strips (1-4-1) when the bridging device (1-5) structure is lowered and in contact with the ground to cope with stability in the negative pressure mode of operation.
The control system comprises:
the control system comprises a controller and a human-computer interface, wherein the output of the controller is in driving connection with an electric drive of the disinfection platform system and two linear motors in the upper channel and the lower channel; the human-computer interface output is connected with the input of the controller.
Step 1, setting operation modes, time, prefabricated parameters and the like through a human-computer interface, and synchronously outputting positive pressure instruction signals or negative pressure instruction signals driven by linear motors in upper and lower channels by a controller so as to realize switching of a positive-negative pressure operation system and prepare for system construction;
step 2, the controller outputs the electric drive of the disinfection platform system to start so as to operate a corresponding mode; after the operation is finished, the controller outputs the electric drive of the disinfection platform system to be closed, meanwhile, the controller serves as a terminal to upload the operation data of the disinfection platform to a server through a communication module, and finally, the linear motors are controlled to drive and adjust respective channels to be in an initialization state;
and 3, waiting for the human-computer interface to receive a new instruction by the system.
As an application, the control system is as shown in FIG. 12.
As shown in fig. 12, the controller outputs the electric driving start of the disinfection platform system to operate the corresponding mode, that is, the flow of the disinfection platform operation is as follows:
step 21, detecting switch and alarm signal for removing fault
Step 211, detecting an electromagnetic door lock switch, a plasma high-voltage fault switch and a fan fault switch, if the electromagnetic door lock switch, the plasma high-voltage fault switch and the fan fault switch have faults, sending out an alarm signal, lighting a red lamp and stopping the machine to an initial state, otherwise, entering step 212;
step 212, further detecting the pressure at the position of the prefilter, if the pressure is normal, entering step 22, otherwise, sending an alarm signal, lighting a yellow lamp, searching for air duct blockage by a display screen, and entering step 22 after personnel are prompted and problems are eliminated;
step 23, the fan starts to work, the plasma high-voltage module starts to pressurize from 2V, the plasma high-voltage module continuously operates, and meanwhile, the feedback voltage current and the feedback flow are detected:
step 231, reading the air flow sensing value, setting a comparison difference value between the sensing value and a set value as delta, and setting a ratio between the comparison difference value and the set value as f; if f is more than or equal to 40 percent and the duration time exceeds 240s, or f is less than 40 percent and the duration time exceeds 360s, an alarm signal is sent out, a red lamp is turned on, and the machine is stopped to be in an initial state; if f is less than 40% but the duration time does not exceed 240s, an alarm signal is sent out, a yellow lamp is turned on, and readjustment is waited for an unstable state; continuously running;
step 232, if the high voltage is less than or equal to 3KV, the current is less than or equal to 160uA, or the current is more than or equal to 1800uA, and the duration time exceeds 240s, an alarm signal is sent out, a red lamp is turned on, and the machine is stopped to an initial state; if the high voltage is more than 3KV and less than 5KV, or the current is more than 160uA and less than 500uA, and the duration time exceeds 240s, an alarm signal is sent out, a yellow lamp is turned on, and the unstable state is waited for readjustment; otherwise, the stable high voltage is more than 5KV, the current is more than 500uA and less than 1800uA, and the operation is continued;
and step 24, counting down the whole machine, and reporting the operation data of each module to the server by the communication module in the controller at regular time. As an application, when the server receives the operation data of each mobile clean room, the operation and service time of each module in the disinfection platform can be known after long-term accumulation, and the operation and service time can be used as the basis for supervision and maintenance. The pre-filter may be considered a consumable. In order to ensure the sterilization effect and energy efficiency of the sterilization platform, the plasma high-pressure module also needs to be maintained on time.
