Description

Pipe plug assembling and disassembling device

Technical Field

The utility model provides a utility model discloses a stopcock handling ware, relates to physics experimental apparatus and makes and the construction of tourism sightseeing facility and tourism industry field, aims at solving physics experimentation and uses the problem that sightseeing facility process need load and unload the stopcock on the test tube.

Background

Since the discovery of geography, the european science and technology has gradually formed a natural science system of many subjects such as mathematics, physics, chemistry, biology, astronomy and geography in the initial detection process of air pressure and water pressure, and the experiment is a brand-new method for discovering the natural science law.

The installation of the stopcocks is an already solved experimental operating specification in laboratories, but in tourist sightseeing facilities, test tubes and stopcocks are located in places where people cannot approach, the length of the test tubes is increased from tens of centimeters to over 12 meters, and under such conditions, especially for students and children, in dangerous environments, the installation and removal of the stopcocks form technical problems that must be solved.

In the chemical experiment, the test tube is used for containing combustible materials to carry out chemical reaction, so that combustion and explosion occur, and certain acid, alkali and salt corrode and burn human skin, so that the test tube is dangerous, in the process of sealing chemical drugs, a tool like tweezers is needed to clamp a tube plug of the test tube to operate, and the harm of chemical change to a human body is avoided.

Apart from experiments performed in school experiments with appropriate equipment and efficient and standardized procedures, individual and specific experiments have historically not been able to be performed indoors. For hundreds of years, particularly after the Xin Hao revolution of China, western schools are developed, and even a complete national education system is formed in the contemporary era, certain physical and chemical experiments can be carried out only in the form of stories and are handed over by teachers or lessons in languages and characters, and various works, character reports and records for re-experiments and repeated experiments are basically not specifically carried out.

Experiments for proving the existence of atmospheric pressure and experiments for testing the atmospheric pressure comprise famous Magdeburg hemispheres experiments, Pascal barrel crack experiments, atmospheric pressure supporting water column experiments and the like, in the teaching of primary and secondary schools in China, many basic physical experiments and chemical experiments are lacked in the demonstration experiments which are successfully carried out by teachers for students due to the fact that college entrance examination and secondary entrance examination are conducted due to liberation. No teacher organizes students to leave a great grassland of inner Mongolia for tourism in summer and finishes the Magdeburg hemispheres experiment in a mode of pulling 16 horses in pairs, the two Magdeburg hemispheres are meshed, air in the spheres is exhausted, the 16 horses are used, 8 pieces of the two hemispheres are pulled in opposite directions respectively, the two hemispheres are possibly pulled apart, the two hemispheres are possibly not pulled apart, the existence of the atmospheric pressure is proved, the atmospheric pressure is also proved to have quite large acting force, and no report of the Magdeburg hemispheres experiment actually made at home is provided so far.

The liquid column is supported by atmospheric pressure, and Pascal experiments prove that the liquid column can support 760mm mercury column and is expressed by P according to the atmospheric pressure formula of physics₀The calculation is rho gh, the water column with the vertical height of more than 10 meters can be supported, namely, besides Pascal barrel cracking experiments which are carried out in Paris France more than 200 years ago, Pascal stands on the third floor counted from bottom to top by a cup of water, a new wood barrel is burst through a pipe, the existence of the pressure inside the liquid is proved, the pressure is irrelevant to the quality of the liquid and only relevant to the height of the liquid column formed by the liquid, and the Pascal barrel cracking experiments are specifically operated and demonstrated outdoors, so that the method is an interesting work, is the inheritance and application of physical knowledge and experiments, and has the promotion effect on the study of primary and primary school students and the scientific popularization effect on most people who have a bad smell and have seen no physical experiments in China.

The atmospheric pressure can completely support the mercury column with the height of 760mm, people naturally think that the atmospheric pressure can support the water column with the height, the height of the water column supported by the atmospheric pressure is calculated by a physical formula and exceeds 10 meters, the method is a physical phenomenon that hundreds of millions of people in China have no hearing and sight to see, the experiment that the atmospheric pressure supports the mercury column with the height of 760mm is completed indoors and the experiment that the atmospheric pressure supports the water column with the height of 10 meters is completed outdoors, and a plurality of specific problems need to be solved, so that the method is beneficial to social development, creates beneficial effects in the fields of human science and social science, is a fundamental way, is implemented in a science and technology museum in a large city, creates and completes the experiments in tourist attractions, and is an industrial form capable of being handled by applying the existing scientific technology, new material, new process and new method, the test tube water which is longer than 10 meters is used, and the installation and the disassembly of the tube plug for sealing the tube opening are a specific difficult problem, and the effect of taking the tube plug by directly using tweezers in a laboratory is much more difficult.

The multifunctional sightseeing device has the advantages that Pascal barrel crack experiments and experiments of which the atmospheric pressure supports 10 meters of high water columns are converted into sightseeing facilities of scenic spots in mountainous areas, the multifunctional sightseeing device has the strategy of supporting rural poverty alleviation and hardness removal and the industry thereof, can be continuously developed after poverty alleviation, can be used for extracurricular physical teaching activities and scientific popularization, and improves sightseeing, activities and learning interests of tourists, and is an outdoor activity actively participated by people.

The experiment of supporting the water column by water pressure is completed, people cannot jump into a water pool to pick up the pipe plug arranged inwards on the pipe orifice, a great deal of difficulty and inconvenience are brought to the people by considering the change of the temperature in spring, summer, autumn and winter, the interest of tourists in sightseeing, the experiment frequency and the efficiency generated by the experiment time cannot be influenced, more tourists can complete the experiment manually, and the experiment is one of the social benefits which must be considered for building tourism sightseeing facilities.

Under the background, the inventor thinks of a novel pipe plug loading and unloading device which is invented and created and used for solving the technical problems of the process of installing the pipe plug in a large-scale and medium-scale experimental process in a water pool by scenic tour facilities and the technical problem of installing the pipe plug on a long test tube.

In order to smoothly complete the loading and unloading of the tube plug on the test tube, after the test tube is filled with water, the tube plug device is used for closing the tube opening of the test tube to ensure that no air bubbles exist in the closed water column in the test tube, the tube plug of the test tube installed at the tube opening position of the test tube is ensured not to be separated from the test tube in the process of rotating the test tube along a fulcrum of a fixed test tube, and when the tube opening of the test tube is completely submerged below the water surface, the tube plug installed at the tube opening position can be conveniently disassembled to separate the tube plug from the test tube, so that the invention provides the test tube loading and unloading device.
