Abstract
The utility model provides a liquid heat convection experimental instrument, which comprises a heating tank, an observation tube, and a thermometer. The experimental instrument is characterized in that the observation tube (3) is arranged on one side of the heating tank (2) with a lid (1), the heating tank and the observation tube are made into a whole through a communicating pipe (4), a cover (5) is arranged at the upper end of the observation tube, two to three holes (6) are arranged on the cover, the thermometer (7) is firmly inserted into the holes, and the thermometer is positioned at the upper position and the lower position in the observation tube. The utility model overcomes the deficiency that the special purpose instrument equipment is not provided when a liquid heat convection experiment is performed in the primary school nature study at present, and provides an instrument which is not easy to cause misunderstanding and can visually observe the liquid heat convection.
Description
Technical field
The utility model relates to the instruments used for education field, the instrument that uses in a kind of liquid convection experiment of more specifically saying so.
Background technology
At present in the nature study in carrying out the liquid heat convection experiment, there is not special-purpose instrument and equipment, the method that use recent decades: in beaker, put water, add a little potassium permanganate in the water, be placed on the spirit lamp and heat, explain the thermal convection phenomenon of liquid by the diffusion of observing red potassium permanganate, its method is simple, equipment is easy to get, its shortcoming is that students' union produces: the diffusion of potassium permanganate is the effect of convection current, the effect of bubble when still heating, the effect of still rocking, the teacher will change time of several times sometimes proves that this is the thermal convection phenomenon.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and is difficult for misunderstanding, and can observe the instrument of liquid heat convection current intuitively.
Technical solution of the present utility model: the utility model is made up of heating tank, inspection section, thermometer, it is characterized in that: a heating tank that has lid, one side of jar has an inspection section made from glass or transparent plastic, rely on communicating pipe to make one between the two, there is a lid inspection section upper end, has covered 2-3 hole, and the hole internal fixation is inserted with thermometer, thermometer is in upper and lower position in the inspection section, is used to show that the water temperature of diverse location changes.
The utility model difference from prior art: be convenient to observe, can not misunderstand, easy and simple to handle.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Description of drawings
Accompanying drawing is structural representation figure of the present utility model.
Specific embodiments
Referring to figure, a heating tank (2) that has lid (1), one side of jar has an inspection section made from glass or transparent plastic (3), rely on communicating pipe (4) to make one between the two, there is a lid (5) the inspection section upper end, covered 2-3 hole (6), the hole internal fixation is inserted with thermometer (7), and thermometer is in upper and lower position in the inspection section.
Claims (2)
1. liquid heat convection experiment instrument, form by heating tank, inspection section, thermometer, it is characterized in that: a heating tank (2) that has lid (1), one side of jar has an inspection section (3), rely on communicating pipe (4) to make one between the two, there is a lid (5) the inspection section upper end, has covered 2-3 hole (6), and the hole internal fixation is inserted with thermometer (7) thermometer and is in upper and lower position in the inspection section.
2. by the described liquid heat convection experiment of claim 1 instrument, it is characterized in that: inspection section is made with glass or transparent plastic.
