Those skilled in the art can make similar generalizations without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0030] Embodiment 1:

[0031] As Figures 1 to 3 shown, the present invention discloses a system for cleaning the lid of a coal sample bucket, which includes an analysis collector, a sample bucket 1, an air compressor 2, a pipeline, an electric control valve, a nozzle, and a cleaning module.

[0032] As Figure 3 shown, the sample bucket 1 includes a bucket body, a bucket lid, and a relay KM. The bucket body is rotatably connected to the bucket lid to be closed or opened.

The air compressor 2, and the electric control valve is a solenoid valve Y1. The air compressor 2 is connected and conducted to the nozzle through a pipeline and the solenoid valve Y1. The nozzle is used to eject air to clean the bucket lid.

[0033] As Figure 1 shown, the control end of the analysis collector is connected to the control end of the relay KM.

[0034] As shown Figure 2 in Figure Figure 2 , the normally open contact KM1 of the relay is connected to the control terminal of the solenoid valve Y1. When the normally open contact KM1 is turned on, the control terminal of the solenoid valve Y1 is powered on, the solenoid valve Y1 is turned on, and the nozzle sprays air to clean the bucket lid.

[0035] The cleaning module is used to analyze and collect the collector to send the capping instruction to the relay. The relay obtains the capping instruction sent by the analysis and collection collector.

The normally open contact KM1 of the relay conducts and notifies the electric control valve to conduct. When the relay obtains the lid shrinking instruction sent by the analysis collector, the normally open contact KM1 of the relay remains conducting and notifies the electric control valve to conduct. When the relay obtains the lid shrinking completion instruction sent by the analysis collector, the normally open contact KM1 of the relay disconnects and notifies the electric control valve to close.

[0043] Among them, the sample bucket, air compressor, pipeline, electric control valve, nozzle itself, and the corresponding electrical connection technology are existing technologies and will not be elaborated here.

[0044] The technical contribution of this application lies in cleverly using the normally open contact KM1 of the relay on the existing sample bucket, connecting it to the control end of the electric control valve, and when the normally open contact KM1 conducts, the control end of the electric control valve is powered on, the electric control valve conducts, and the nozzle sprays air to clean the bucket lid.

[0045] Embodiment 3:

[0046] As Figure 4 shown, the present invention discloses a method for cleaning the lid of a coal sample bucket. Based on the system of Embodiment 1, it includes a cleaning step. The cleaning step includes the analysis collector sending the capping instruction to the relay. The relay obtains the capping instruction sent by the analysis collector, the normally open contact KM1 of the relay conducts and notifies the electric control valve to conduct. When the relay obtains the lid shrinking instruction sent by the analysis collector, the normally open contact KM1 of the relay remains conducting and notifies the electric control valve to conduct.

[0049] Relative to the above embodiments, other embodiments can also be adopted. For example, the electric control valve is an electrically controlled pneumatic valve.

[0050] Relative to the above embodiments, other embodiments can also be adopted. For example, the barrel body is hinged to the barrel lid.

[0051] Compared with the above embodiments, the program modules therein can also be hardware modules made by using existing logic operation technologies to implement the corresponding logic operation steps, communication steps, and control steps, and further implement the above corresponding steps. The logic operation unit is the prior art and will not be elaborated herein.

[0052] Concept of the present application:

[0053] It is an automatic cleaning method for a coal sample collection system, aiming to solve the problems of reducing staff and increasing efficiency, improving the automation level of equipment, reducing the labor intensity of operating personnel, while enhancing personal and equipment safety, improving the environmental protection level, saving energy and reducing emissions, and enhancing the reliability of equipment.

[0054] Automatic cleaning control method: Analyze the automatic encapsulation action process of the collector. There is a 2-second time gap and logic output during the process of capping and locking the lid. The space at the capping and locking positions is sufficient. By using the time gap, logic output, and sufficient installation space, and on the premise of meeting the functions, the minimum modification can be made. By controlling the timing and fixed-point output of compressed air through the control loop, the timed and fixed-point cleaning of the bucket lid by compressed air can be realized.

[0055] Technical solution description:

[0056] The sample bucket automatic encapsulation system includes: fully automatic bucket locking and fully automatic bucket opening. The locking and unlocking of the bucket lid are realized by the contact of two external electrodes with the bucket lid and the positive and negative conversion of the electrodes. In actual operation, since there is inevitably coal dust and dust in the production site. After a large amount of coal dust, dust, etc. adhere to the bucket lid, it will affect the contact between the external electrode and the bucket lid, thus affecting locking and unlocking. Due to limited space at the site, it is impossible to install a contact cleaning device. Previously, a fan was used for blowing, but due to the certain adsorption of coal dust and limited wind power, effective cleaning could not be achieved. After experiments, after introducing the automatic cleaning method with compressed air as the medium, a good cleaning effect is obtained.

[0057] The automatic cleaning device with compressed air as the medium includes: an air compressor, a compressed air pipeline, a solenoid valve, and an air nozzle. Each time the external electrode acts, that is, when the locking and unlocking actions are performed, the normally open point of the external electrode contactor KM1 triggers the solenoid valve to open, and compressed air is ejected from the nozzle to blow the bucket lid, achieving an effective cleaning effect.

[0058] This automatic cleaning device based on compressed air is ingeniously designed, simple and practical, and is relatively easy to maintain. It not only greatly reduces the time of manual cleaning but also greatly improves the success rate of contact bucket locking, providing a reliable guarantee for the automatic encapsulation of Shang'an Power Plant.

[0059] After the present application has been running internally for a period of time, the beneficial points feedback by on-site technical personnel are as follows:

[0060] This product has strong versatility, low cost, long service life, and is simple and convenient to maintain. As long as it is a coal sample collection and automatic encapsulation system, this achievement can be used for reference.

[0061] At present, the technical solution of the present invention has been pilot-tested, that is, a smaller-scale test before large-scale production; after the pilot test, user surveys have been carried out on a small scale, and the survey results show a relatively high user satisfaction; now preparations are underway for the formal production and industrialization of the product (including research on intellectual property risk early warning).
