Abstract

A long tail type Cartesian diver is used for indicating obvious water level change in middle school experiments. The long tail type Cartesian diver is characterized by comprising a colored transparent air bubble (1), the bottom of the air bubble is connected with a colored transparent cone-shaped long tail inlet/outlet pipe (3), and an annular counterweight body (2) is sleeved on the upper portion of the cone-shaped long tail inlet/outlet pipe. A traditional Cartesian diver is replaced by the provided Cartesian diver, the water level in the Cartesian diver is clearly displayed, and the demonstration effect in an experiment class is substantially raised.

Description

Long-tail type Cartesian diver

Technical field

The utility model belongs to teaching and experiment equipment field, specifically refers to especially significantly long-tail type Cartesian diver of a kind of its SEA LEVEL VARIATION for experiment in middle school.

Background technology

Cartesian diver is the experimental apparatus that middle school teaching is conventional, and material is multiple, and profile is various, easy to manufacture.Although but traditional Cartesian diver can be demonstrated its process of drifting along, exist a common fault to be: the Cartesian diver inside variation of water level does not see Chu, makes presentation process just as magic, be unfavorable for that teacher explains scientific knowledge wherein.

Summary of the invention

The purpose of this utility model: provide a kind of in the process of drifting along, the Cartesian diver that SEA LEVEL VARIATION is especially obviously easily shown in.

The utility model is taked technical measures for reaching above-mentioned purpose: described Cartesian diver has colored transparent air bubble (1), air bubble bottom connection colored transparent taper long-tail water inlet pipe and water outlet pipe (3), tapered tube top is overlapped ring-type balance weight body (2).

The structure of described Cartesian diver has guaranteed that it can be upright in water, and cause when the water level that enters tapered tube during lower than B point Cartesian diver toward floating, the water level in entering tapered tube during higher than A point Cartesian diver sink.Also, because adopted colored transparent taper long-tail type water inlet pipe and water outlet pipe, cause the interior SEA LEVEL VARIATION of pipe obvious especially, clear and easy to see.

The beneficial effect that this practicality is new: substitute traditional Cartesian diver by water level height in clear demonstration Cartesian diver with described Cartesian diver, greatly improve the experimental demonstration effect of experimental teaching on classroom.

Accompanying drawing explanation

Fig. 1 is the utility model profile and structural representation.

Each several part title in figure: 1-colored transparent air bubble; 2-ring-type balance weight body; 3-colored transparent taper long-tail water inlet pipe and water outlet pipe.

Embodiment

In the embodiment shown in fig. 1, colored transparent air bubble (1) is positioned at that top, colored transparent taper long-tail water inlet pipe and water outlet pipe (3) are connected to air bubble bottom, taper long-tail pipe top overcoat has ring-type balance weight body (2).

Claims

1. for the especially obvious long-tail type Cartesian diver of its SEA LEVEL VARIATION of experiment in middle school, it is characterized in that: have that colored transparent air bubble (1), air bubble bottom connect colored transparent taper long-tail water inlet pipe and water outlet pipe (3), long-tail tapered tube top cover has ring-type balance weight body (2).
