As shown in fig. 1, the embodiment provides a method for cleaning a closed air duct of an unstructured air duct, which includes the following steps:
s1, placing an internal vacuum air bag 2 in the non-structural air duct 1, wherein the air bag 2 is matched with the size of the non-structural air duct 1;
s2, inflating the air bag 2, wherein the air bag 2 is inflated until the outer surface of the air bag 2 is clung to the inner wall of the unstructured air duct 1, so that garbage in the unstructured air duct 1 is extruded between the outer surface of the air bag 2 and the inner wall of the unstructured air duct 1, and a ventilation opening corresponding to the unstructured air duct 1 is formed on the inner surface of the air bag 2;
s3, judging whether the air bag 2 needs to be replaced or not by detecting the use state of the air bag 2, or replacing and using the air bag 2 after the set use time is separated; the replacement method of the air bag is as follows, the air in the air bag 2 is discharged, the air bag 2 is taken out, a new air bag 2 is put into the unstructured air duct 1, and the air bag is inflated again for use.
In the above cleaning method, before the air bag 2 is not put in, the non-structural air duct 1 is filled with the pollutants such as garbage, after the air bag 2 is put in, the non-inflated air bag 2 only occupies a small part of the internal space of the non-structural air duct 1, after the air bag 2 is correctly put in place, the air bag 2 begins to be inflated gradually, when the air bag 2 is inflated until the outer surface of the air bag 2 is in contact with the inner wall of the non-structural air duct 1, the air bag 2 keeps the current state, the pollutants in the non-structural air duct 1 are already covered between the air bag 2 and the non-structural air duct 1, and the ventilation opening 4 with the approximate size of the non-structural air duct 1 is formed on the inner surface of the air bag 2, so that ventilation quantity is not affected, and ventilation pollution caused by improper cleaning in the later period is reduced. The inflated air bag 2 has a ring structure with the size matched with that of the unstructured air duct 1, and the unstructured air duct 1 with different sizes needs to be dealt with in preparation of the air bag 2. After the air bag 2 is used for a period of time, considering the situation that the ventilation amount is reduced due to pollution or shrinkage of the air bag 2, the air bag 2 needs to be replaced in time, and two methods for judging whether the air bag 2 needs to be replaced are mainly adopted, wherein the first method is to detect the use state of the air bag 2, and the second method is to set a time, and the air bag 2 is replaced when the time is up. The first method may be to detect whether the air flow in the air bag 2 is greatly reduced, or detect whether the ventilation volume of the ventilation opening formed on the inner surface of the air bag 2 is reduced, where the specific reduction range may be that the air flow in the air bag 2 is reduced by more than 15% compared with the initial flow, that is, the air bag 2 needs to be replaced, and the ventilation volume is reduced by more than 10% compared with the initial ventilation volume, that is, the air bag 2 needs to be replaced. The time set by the second judgment method may be ten days, or may be adjusted up or down according to the specific condition of the airbag 2, and may be judged and set according to past use experience.
In order to ensure the quality of the air bag 2 during use, the air bag 2 is preferably made of a high-density lightweight polyester material, and adopts a double-layer vacuum structure, and the shape needs to be matched with the unstructured air duct 1.
In the step of inflating the airbag 2, the alternative inflation modes are mainly divided into two types, one of which is a self-inflating mode of the airbag 2 and the other of which is an external inflation mode. The self-inflating mode is that after the air bag 2 is placed in the non-structural air duct 1, the air bag 2 is inflated and then tightly covered in the non-structural air duct 1 by opening an automatic inflation valve.
The self-inflating mode airbag structure comprises an airbag body, an airbag packaging bag, an air generator and a linkage guy cable; the balloon body is a flexible, fully sealed pouch; the air bag body is arranged in the air bag packaging bag, and two ends of the air bag body are fixedly connected with the air bag packaging bag; the gas generator and the linkage inhaul cable are arranged in the airbag body; one end of the gas generator passes through the air bag body to be connected to the air bag packaging bag, a switch on the other end of the gas generator is connected to one end of the linkage inhaul cable, and the other end of the linkage inhaul cable passes through the air bag body to be connected to the air bag packaging bag; the air bag package is a sealed bag which can be torn. The scheme adopts the structure that the air bag package bag is provided with the air bag body, so that the product is convenient to store and carry, and the air bag body is prevented from being scratched, stabbed or accidentally opened; because the gas generator is arranged in the air bag body and is used for generating gas required by the expansion of the air bag, the air bag is in a flat folding state without gas at the beginning, and is inflated in the using process; the linkage inhaul cable is adopted, so that the tearing force of the air bag packaging bag can be transmitted to the switch of the gas generator, the gas is released to expand the air bag, and the structure is simple and reliable and the operation is convenient.
For the inflation mode of the second airbag, the airbag 2 is assisted and automatically inflated by adopting an externally arranged automatic inflation device 3, and the automatic inflation device 3 can be connected to an inflation inlet of the airbag 2 through an air pipe. By operating the automatic inflator 3, the valve on the automatic inflator 3 is opened, and the gas stored in the cylinder rapidly enters the airbag 2 so that the airbag 2 can be rapidly inflated.
To make up for the scheme of inflating by using the automatic inflator 3 that is externally provided, in the process of inflating the airbag 2 by the automatic inflator 3, when the detected air amount in the airbag 2 reaches the preset air threshold value, the automatic inflator 3 automatically stops inflating. Specifically, a switch valve is arranged on an air pipe connected with the automatic inflating device 3 and the air bag 2, the switch valve is used for setting an air threshold, when the air quantity conveyed by the air pipe reaches the air threshold in the process of inflating the air bag 2 by the automatic inflating device 3, the switch valve is automatically closed to cut off an air conveying channel, the air bag 2 is stopped to be inflated, and the condition that the air bag 2 is burst due to excessive inflation can be prevented by adopting an automatic closing mode, so that unnecessary resource waste is avoided. As for the air threshold value to be set, it is necessary to adjust according to the size of the air bag 2, it is found by performing an experiment on the air bag 2 how much air the air bag 2 needs to reach the data attached to the inner wall of the non-structural duct 1, and then the air threshold value is set according to the data. The same applies to the air thresholds to be set for the air bags 2 of different sizes, and thus the setting of the air thresholds needs to be rationally adjusted according to the actual situation.
Different from the scheme for controlling the inflation termination, the scheme adopts that a plurality of sensors are arranged on the inner wall of the non-structural air duct 1, the sensors are electrically connected with the automatic inflation device 3, and the sensors are used for detecting whether the outer surface of the air bag 2 is propped against the inner wall of the non-structural air duct 1; after the automatic inflating device 3 starts to inflate the air bag 2, when the sensor detects that the outer surface of the air bag 2 is propped against the inner wall of the unstructured air duct 1, a relevant control signal is sent to the automatic inflating device 3 to control the automatic inflating device 3 to stop inflating; when the sensor does not detect that the outer surface of the air bag 2 is propped against the inner wall of the unstructured air duct 1, the automatic inflating device 3 keeps continuously inflating. The method of judging whether the air inflation state of the air bag 2 meets the requirement is more visual through the set sensor, and compared with the method of setting the air threshold value, the method is more direct and accurate, the aim of inflating the air bag 2 is to enable the outer surface of the air bag 2 to be clung to the inner wall of the unstructured air duct 1 so as to achieve the aim of shielding garbage, and meanwhile, the ventilation quantity of the ventilation opening 4 formed on the inner surface of the inflated air bag 2 is required to meet the requirement. In this scheme, the sensor may be a photoelectric sensor, an infrared sensor, or the like.
As shown in fig. 2, the present embodiment provides a closed cleaning device for an unstructured air duct, including: a non-structural air duct 1, an air bag 2 and an inflating device 3, wherein the shape of the air bag 2 corresponds to the internal shape of the non-structural air duct 1, the air bag 2 is detachably arranged in the non-structural air duct 1, the inflating device 3 is arranged outside the non-structural air duct 1 and is connected with the air bag 2, the air bag 2 has an initial state and an inflating state, and when the air bag 2 is in the initial state, the air bag 2 is in contact with or not in contact with the inner wall part of the non-structural air duct 1; when the air bag 2 is in an inflated state, the outer surface of the air bag 2 is in complete contact with the inner wall of the unstructured air duct 1, and the inner surface of the air bag 2 forms a ventilation opening 4;
the closed cleaning device of the unstructured air duct is configured to: the air bag 2 in the initial state is placed in the non-structural air duct 1, the air bag 2 is inflated through the inflation device 3, the air bag 2 is gradually inflated from the initial state to the inflated state, the outer surface of the air bag 2 is fully abutted against the inner wall of the non-structural air duct 1, and a ventilation opening is formed in the inner surface of the air bag 2.
In the above-mentioned scheme, the airbag 2 is inflated by adopting a mode of externally connecting the inflator 3, and in addition, an automatic inflation mode can be adopted, so that the requirement of inflating the airbag 2 can be met without connecting the external inflator 3. The specific structure is described in the above scheme and will not be described here.
Considering the complexity of the structure of the non-structural air channels 1, in the scheme, a plurality of non-structural air channels 1 are arranged, each non-structural air channel 1 is detachably connected to form a main air channel, and the air bag 2 is detachably arranged in the main air channel. In this scheme, a gasbag 2 corresponds a plurality of unstructured wind channel 1, according to the structure of every unstructured wind channel 1 some on the matching gasbag 2, because gasbag 2 is good elasticity, consequently can adapt to the unstructured wind channel 1 of various different shapes, also can reach the effect of attached inner wall in the wind channel junction of unevenness, be detachable between each unstructured wind channel 1 moreover, can dismantle follow-up maintenance or change of being convenient for to a certain unstructured wind channel 1, also can conveniently change gasbag 2 after dismantling unstructured wind channel 1. Specifically, the unstructured air duct 1 is provided with five smooth overjoints and is identical in structure, and every fifth of the air bag 2 corresponds to one unstructured air duct 1 at this time. In addition, the mounting relation of the air bags 2 and the non-structural air channels 1 can be interchanged, one air bag 2 can be independently arranged for each non-structural air channel 1, and the non-structural air channels 1 with different structures are referred to herein, so that the air bags 2 can be matched with each non-structural air channel 1 to the greatest extent, and the achieved effect is more excellent. In addition, one unstructured air duct 1 can correspond to a plurality of air bags 2, in the mode, aiming at the situation that the structure of a single unstructured air duct 1 is quite complex, one air bag 2 cannot be used for covering the inner wall of the unstructured air duct 1, one air bag 2 is adaptively selected for each special structure of the unstructured air duct 1 to be installed, and therefore the complex unstructured air duct 1 can be guaranteed to be closed and cleaned in the mode.
In order to further ensure the ventilation effect after the air bag 2 is installed in the non-structural air duct 1, the size between the air bag 2 and the non-structural air duct 1 needs to be strictly designed, specifically, the cross-sectional area of the air bag 2 in the inflated state is a, the cross-sectional area of the non-structural air duct 1 is b, and the cross-sectional area ratio between the air bag 2 and the non-structural air duct 1 is c, wherein c=a/b, and 1% +.ltoreq.c+.ltoreq.15%. The air bag 2 in the inflated state occupies a part of ventilation area in the non-structural air duct 1, in order to ensure ventilation quantity, the cross section area ratio c between the two needs to be controlled within a certain range, and the preferable ratio is c=1%, and under the ratio, the air bag 2 occupies the minimum ratio in the non-structural air duct 1, and the influence on ventilation quantity is minimum; when the ratio c increases, the air bag 2 increases in the non-structural duct 1, and the ventilation amount decreases, but the tolerance of the air bag 2 increases, so that a limit ratio c=15% is set, and when the ratio c exceeds 15% and is not available, the ventilation amount is greatly affected. In this range, the ratio c may be set according to the requirement for ventilation, and an optimum ratio may be selected.
In some embodiments, the non-structural air duct 1 is provided with an inlet into which the air bag 2 is placed, and the door plate is hinged at the inlet. The entrance is opened or closed through the switch of the door plate, the air bag 2 can be put into the entrance, the door plate sealing unstructured air duct 1 can be closed after the air bag 2 is put into the air bag for inflation, and the door plate switch mode is more convenient and safer.
In view of safety in inflating the airbag 2, an air valve is provided on a pipe connecting the inflator 3 and the airbag 2, so that the inflation of the airbag 2 can be stopped at any time to cope with dangerous emergency.
Preferably, the airbag 2 has a double-layer structure, and the airbag 2 is made of polyethylene terephthalate, or polybutylene terephthalate, or polyethylene naphthalate material. The air bag 2 is preferably made of high-density light-weight polyester material, so that the air bag 2 can have longer service life in the unstructured air duct 1 and avoid frequent replacement, and the specific materials are only preferable but not limited to the above materials.
In summary, compared with the prior art, the novel method can effectively reduce the pollution of the cleaning of the interior of the air duct to the whole ship in the production process, secondly reduce the labor for cleaning the narrow unstructured air duct, improve the effectiveness, generally achieve the purposes of reducing the difficulty of cleaning the unstructured air duct and achieving the effect of cleaning the interior of the air duct; meanwhile, the risk of pollution and service life reduction caused by corrosion of damaged areas exposed to the ocean high-humidity environment due to damage of the air duct caused by modification is reduced, and air is completely isolated from contacting the surface of the air duct.
