Detailed Description
In order that the invention may be readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the testing device in this embodiment includes a testing box, which includes a box body 1 with an opening at one end, and a cover body 2 hermetically fitted with the box body is disposed at the opening. When in testing, the tested equipment and the fumigation reagent are firstly put into the box body 1, and then the box body 1 and the cover body 2 are assembled in a sealing way to form a sealing space for testing so as to maintain the concentration required by the testing, and the sealing space can avoid the situation that the fumigation gas in the box body has insufficient concentration and the fumigation reagent is required to be supplemented into the box body in the testing process because the fumigation gas leaks outside due to poor air tightness of the box body in the testing process as much as possible. Of course, the device also comprises a test monitoring system for monitoring the test environment information in the box body, and the test monitoring system can at least monitor the concentration of the fumigation gas so as to monitor whether the fumigation gas leaks in the test process in real time, and if the fumigation gas leaks in the box body, the concentration of the fumigation gas in the box body cannot meet the test requirement and the fumigation reagent needs to be timely supplemented into the box body.
The embodiment mainly optimizes phosphine gas most commonly used in the existing granary fumigation method to carry out fumigation resistance test on tested equipment, and the concentration of the phosphine gas in the closed space is more than or equal to 500mL/m 3 . The tested equipment comprises a camera, a grain system collector, a humidity sensor, a gas sensor, a pest sensor and the like, and the phosphine gas has a practical significance and is more practical because of strong corrosiveness to electronic equipment.
In practical application, the phosphine gas is mainly obtained by reacting aluminum phosphide, zinc phosphide, calcium phosphide and the like with water molecules in the air, the fumigation reagent in the embodiment is preferably aluminum phosphide, the aluminum phosphide is generally solid powder or tablet, residues are left after the reaction is finished, and the aluminum phosphide can be separated from the tested equipment for treatment, and is placed in a small independent space. Therefore, in this embodiment, a putting hole 14 dedicated for putting aluminum phosphide is provided on the test box, and the putting hole is far smaller than the size of the opening of the box body, a placing box 5 dedicated for placing aluminum phosphide corresponding to the putting hole is further provided in the test box, and a gas diffusion hole 6 is provided on the wall of the placing box. The gas diffusion holes 6 may be at least one large hole having a larger diameter or a plurality of small holes having a gauze shape, and the specific structure thereof is not limited by the description, so long as the phosphine gas can be diffused to the whole tank. Of course, in order to maintain the airtight of the space inside the tank, the dispensing hole is also equipped with a hole cover 4 in sealing engagement therewith. Because phosphine is extremely toxic, when the concentration in the box body is reduced to the concentration required to be supplemented with aluminum phosphide, the operation through the throwing hole is far smaller than the operation of opening the cover body of the test box to cause the leakage of the phosphine, so that the relative injury to people is smaller, and the safety of operators is ensured.
The putting hole 14, the matched hole cover 4 and the placing box can be arranged on the box body 1 or the cover body 2, and the arrangement position of the putting hole does not influence the tightness of the test space. In addition, the structure of the placing box for placing the aluminum phosphide is various, and square structures, round shapes or other irregular shapes can be used.
The test device of the invention fills the phosphine gas required by the test in a closed space (in the embodiment, the phosphine gas is generated by the reaction of aluminum phosphide and moisture in the air), the tested equipment is placed in the closed space for a period of time, the time can be determined according to the test content and the actual condition, and the tested equipment is taken out for detection after the test time is reached, so as to judge whether the performance parameters of the tested equipment reach the standards. The test environment information in the box body, mainly the concentration information of phosphine gas, must be monitored in real time in the test process, so that the concentration information is always kept in the range of the test requirement, and once the concentration reduction is found to not meet the concentration requirement required by the test, the concentration reduction must be immediately supplemented to keep the reliability of the test. The device can simulate the actual environment (mainly concentration environment) of the granary in fumigating and disinsection well, carry out fumigating-resistant test on some equipment (including sensors, collectors and the like) which are easy to be corroded by phosphine gas, and the concentration of the phosphine gas in the test is higher than that of the actual granary environment, so that the test reliability is high, and the reliability of the test result is high.
Further, in order to further prevent outward diffusion of phosphine gas when replenishing aluminum phosphide, the device is further provided with a blocking mechanism for blocking and opening the gas diffusion holes, which prevents leakage of phosphine gas in the case to outside the case when adding aluminum phosphide from the delivery hole to the placement case.
The throwing hole 14 of the aluminum phosphide and the hole cover 4 in sealing fit with the throwing hole are arranged on the box body 1; the placing box 5 is preferably a cylindrical structure with one end open and one end closed, the open end of the placing box corresponds to the throwing hole 14 of aluminum phosphide, and the placing box 5 is fixedly connected with the test box 1. As shown in fig. 2, which is an enlarged view of a structure of an embodiment of the plugging mechanism, the plugging mechanism of the embodiment comprises a ring 15 for performing rotation operation and a plugging piece arranged on the ring, extending towards the inside of the box body 1 and rotationally fitting with the side wall of the placement box 5, wherein a round hole 18 is arranged in the center of the ring, corresponds to the aluminum phosphide throwing hole 14, and is in sealing fit with the hole cover 4 so as to ensure the air tightness of the box body; the stopper piece includes a continuous cylindrical portion 16 and an extension portion 17 for covering the gas diffusion holes 6 when rotated to a set position, one end of the cylindrical portion 16 is provided integrally with the circular ring 15, and the other end is provided integrally with the extension portion 17. On one hand, the plugging mechanism can prevent phosphine gas from leaking out during addition; on the other hand, the ring 15 and the cylindrical portion 16 of the sealing mechanism cooperate with each other, so that the sealing effect can be further enhanced when the case is sealed.
The plugging sheet of this embodiment can be either a structure rotationally fitted with the inner wall of the placement box 5 or a structure rotationally fitted with the outer wall of the placement box 5, and both the structures can play a role in covering and plugging the gas diffusion holes 6 during rotation.
In addition, the placing box 5 is fixedly connected with the test box, and the connecting modes are more, for example, the placing box 5 can be fixedly connected with the box body 1 of the test box through two connecting rods, one end of each connecting rod is fixed on the inner wall of the box body 1, and the other end of each connecting rod is fixedly connected with the side wall of the lower part of the placing box 5 (the position where a blocking piece needs to be avoided).
When the plugging mechanism with the structure is adopted, in order to achieve the purpose of plugging, the gas diffusion holes 6 arranged on the side wall of the placement box 5 are required to be anastomosed, namely, the gas diffusion holes cannot completely cover the side wall of the placement box, and the gas diffusion holes can be completely covered when the plugging mechanism rotates to a certain position.
The working principle of the plugging mechanism is as follows: in the test process, once the concentration of phosphine gas in the box body is monitored to be reduced and the condition of the test requirement cannot be met, when an operator adds aluminum phosphide into the box body 1, the operation ring rotates the operation ring to a certain position, the gas diffusion holes 6 are plugged by the plugging sheets, the placing box 5 is isolated from the inner space of the box body 1, the hole cover 4 is opened to add aluminum phosphide with a corresponding dosage, at the moment, because phosphine in the box body cannot be outwards diffused through the placing box 5, the leaked gas is very few, and the personal safety of the operator is further guaranteed by the structure.
In addition, the plugging mechanism is not limited to the above-mentioned structure, and may take other forms, for example, the gas diffusion hole is disposed in the lower region of the side wall of the placement box, and a channel valve is disposed at the upper portion, and the channel valve is closed in the fumigating test process to block outward overflow of phosphine gas, but when aluminum phosphide is added from the delivery hole and a closed cover is covered, the channel valve can be opened to enable the aluminum phosphide to fall at the bottom of the placement box, and then closed. The plugging structure similar to the mechanism can avoid the leakage of the phosphine gas in the box body when the aluminum phosphide is supplemented, and the plugging structure is not listed here.
Further, the test monitoring system of this embodiment includes a detection sensor for monitoring the test environment information in the box, a data acquisition module 11 connected to the output end of the detection sensor, and a data transmission module 10 connected to the output end of the data acquisition module 11, where the output end of the data transmission module 10 is used for communication interconnection with the monitoring terminal. The detection sensor at least comprises a gas sensor 8 arranged in the box body for detecting the concentration value of the phosphine gas, the data acquisition module 11 acquires the concentration value of the phosphine gas sensed by the gas sensor, and the data transmission module 10 transmits the data of the concentration of the phosphine gas acquired by the data acquisition module 11 to the monitoring terminal in a communication manner.
Besides the gas sensor, the detection sensor of the test monitoring system further comprises a temperature sensor arranged inside the box body to detect the temperature value inside the box body and a humidity sensor to detect the relative humidity value inside the box body, so that the temperature and humidity values of the test environment can be observed in real time during testing. The output ends of the temperature sensor and the humidity sensor are connected with the data acquisition module 11; the data acquisition module 11 further acquires a temperature value sensed by the temperature sensor and a relative humidity value sensed by the humidity sensor, and the data transmission module 10 transmits the temperature value and the relative humidity value to the monitoring terminal in a communication manner.
For easy installation and easy sealing of the case, the temperature sensor and the humidity sensor of the present embodiment use an integrated temperature and humidity sensor 7 having two functions at the same time. Of course, the temperature sensor and the humidity sensor can be selected according to actual needs, and can be selected either. The detection heads of the gas sensor 8 and the temperature and humidity sensor 7 are fixed on the inner side wall of the box body 1, and the output end is connected with a signal acquisition module 11 arranged on the outer wall of the box body through a perforation arranged on the side wall.
The output interface of the data acquisition module 11 is an RS232 serial port; the data transmission module 10 adopts a serial port server, the serial port server has the function of converting serial port signals into network signals, an RS232 serial port of the signal acquisition module can be converted into a TCP/IP network interface, and the bidirectional transparent transmission of data of the RS232 serial port and the TCP/IP network interface is realized, so that the signal acquisition module can immediately have the function of the TCP/IP network interface, a connecting network and a monitoring terminal are in data communication, and the transmission distance of the gas sensor acquisition signals is greatly expanded. The monitoring terminal can be an upper computer or a mobile terminal such as a mobile phone and an IPAD, and the upper computer is preferred in the monitoring terminal of the embodiment, wherein the upper computer refers to a monitoring computer which can directly send out a control command, and various signal changes (such as concentration, temperature and relative humidity) are displayed on a screen.
Further, the testing device can further comprise a temperature control mechanism for controlling the temperature in the testing box body and a dry and wet control mechanism for controlling the humidity in the testing box body, and the adoption of the mechanism can change the environmental conditions of the test more conveniently, such as the testing temperature and the relative humidity, so that the actual use environment can be simulated more truly, the reliability of the test is improved, and the application range of the testing device is wider. The temperature control mechanism and the dry and wet control mechanism are in a plurality of realization forms, for example, the temperature control mechanism can adopt a water pipe temperature adjusting mode, a water pipe penetrates through the box body, the joint of the water pipe and the box body is subjected to sealing treatment, or a water pipe assembly is arranged at the bottom of the box body in a disc manner, and the temperature adjustment is carried out by adopting a mode of introducing hot water or cold water into the water pipe; the humidity control mechanism adopts a structure that an atomizer is arranged in a box body, a pressurizing device communicated with the atomizer is arranged outside the box body, when the humidity needs to be increased, water is introduced into the pressurizing device, and then the pressurized water is sprayed into the box body through the atomizer, so that the air humidity in the box body is increased, and the structure similar to a household humidifier can be adopted, and the specific structure is not repeated here.
Further, the test monitoring system of the embodiment may further include a monitoring display module for displaying the phosphine concentration value, the temperature value and/or the relative humidity value in real time, where the monitoring display module is electrically connected with the data acquisition module and may be disposed outside the test box, so as to dynamically display the phosphine concentration value, the temperature value and/or the relative humidity value acquired by the data acquisition module in real time, thereby increasing the intuitiveness of data display and monitoring in the test process.
In addition, the testing device also comprises a power supply 12 and a power supply indicator lamp 9 for indicating whether the power supply module is electrified, wherein a plug 13 connected with a power supply is externally arranged on the power supply module. The power supply module of the embodiment is preferably a switching power supply, can convert 220V alternating current into direct current, supplies power to electric equipment in the device such as a gas sensor, a signal acquisition module, a serial server and the like, and has the advantages of small size, light weight and high conversion efficiency. Of course, in order to facilitate visual observation of whether the power supply is energized, a corresponding power indicator lamp may be provided, and the work indicator lamp is lighted and displayed when ac power is supplied.
In addition, the handle 3 is arranged on the cover body, so that the cover body is more convenient to operate.

The opening of the box body 1, the feeding hole 14 of the fumigation reagent, the perforation arranged on the side wall, the central hole of the circular ring of the plugging mechanism and other parts are all provided with rubber sealing rings (not shown in the figure) so as to ensure the whole device to have good air tightness. Of course, in order to extend other functions, corresponding functional modules may be added as needed.
Based on the same conception, the invention also provides a test method using the fumigating-resistant test device of the granary equipment.
