【摘要】：鼠害是一個(gè)很嚴(yán)重的世界性問題,老鼠的一舉一動(dòng)都可能給人類帶來危害。為了控制鼠類的危害,人們采取器械(鼠籠、鼠夾等)、陷阱、粘鼠板、建筑與設(shè)施防鼠、化學(xué)殺鼠劑、天敵等多種措施與鼠類抗?fàn)�。本論文利用新型電力電子器件和適于更高開關(guān)頻率的電路拓?fù)洌O(shè)計(jì)出一款能發(fā)出大功率、變頻式的超聲波驅(qū)鼠器，并將其合理安放在鼠患嚴(yán)重場(chǎng)所，以此達(dá)到驅(qū)鼠目的。 電力安全生產(chǎn)的重要性是由電力生產(chǎn)、電力基本建設(shè)、電力多種經(jīng)營(yíng)的客觀規(guī)律和生產(chǎn)特性及社會(huì)作用決定的。隨著電力工業(yè)迅速發(fā)展、電力體制改革和市場(chǎng)化進(jìn)程加快，電力安全生產(chǎn)的重要性更加突出，而鼠患對(duì)電力系統(tǒng)會(huì)造成不可估量的危害，本論文根據(jù)電子驅(qū)鼠器的工作機(jī)理和使用技術(shù)，采用多種統(tǒng)計(jì)方法進(jìn)行現(xiàn)場(chǎng)驅(qū)鼠試驗(yàn)。 試驗(yàn)結(jié)果表明，不同頻率、聲壓的超聲波對(duì)驅(qū)鼠效果有較為明顯的影響，其表現(xiàn)為：首先在同一聲壓條件下頻率越高，鼠密度越低，驅(qū)鼠效果越明顯；其次，在同一頻率條件下聲壓越高，鼠密度越低，驅(qū)鼠效果越明顯。此外，研究發(fā)現(xiàn)當(dāng)長(zhǎng)時(shí)間使用某一特定頻率進(jìn)行驅(qū)鼠時(shí)，老鼠對(duì)該特定頻率具有一定的適應(yīng)性，表現(xiàn)為鼠密度上升到接近原來水平。 本文在總結(jié)前人研究的基礎(chǔ)上，深入探究超聲波頻率、聲壓對(duì)鼠類動(dòng)物日常生活的影響以及老鼠對(duì)某一特定頻率的適應(yīng)性周期的研究，并分析總結(jié)最佳驅(qū)鼠方案，最后推廣到家庭、商業(yè)和安全生產(chǎn)等領(lǐng)域的驅(qū)鼠中，為人類的生活、工作及健康安全提供保障。
[Abstract]:Rat damage is a serious worldwide problem. Every move of a mouse can cause harm to human beings. In order to control the harm of rodents, people take various measures to fight against rodents such as cages, traps, traps, stick plates, buildings and facilities for rodent control, chemical rodenticide, natural enemy and so on. In this paper, a new power electronic device and circuit topology suitable for higher switching frequency are used to design a high-power, variable-frequency ultrasonic rat repellent device, which can be reasonably placed in a severely rodent place, so as to achieve the purpose of rat repellent. The importance of electric power safety production is determined by the objective law, production characteristics and social function of electric power production, electric power capital construction, electric power diversified operation. With the rapid development of the electric power industry, the reform of the electric power system and the acceleration of the marketization process, the importance of the electric power safety production becomes more prominent, and the rodent plague will cause incalculable harm to the power system. According to the working mechanism and application technology of electronic rat repellent, this paper adopts various statistical methods to carry out field rodent repellent test. The experimental results show that ultrasonic wave with different frequencies has a significant effect on the rodent repellent effect. Firstly, the higher the frequency under the same sound pressure, the lower the rat density, the more obvious the repellent effect is, and the second is that the higher the frequency is under the same sound pressure, the lower the rat density is. At the same frequency, the higher the sound pressure, the lower the rat density, and the more obvious the repellent effect is. In addition, it was found that when a specific frequency was used for a long period of time, the mice had a certain adaptability to the specific frequency, which showed that the density of the mice increased to the original level. On the basis of summarizing the previous studies, this paper probes into the effects of ultrasonic frequency, sound pressure on the daily life of rodents and the adaptive cycle of mice to a certain frequency, and analyzes and summarizes the best rodent repellent scheme. Finally, it is extended to rodent repellent in family, business and safe production, which provides guarantee for human life, work, health and safety.
