Description

Technical Field

[0001] The utility model belongs to the technical field of popular science display equipment, and particularly relates to a popular science exhibit based on the principle of object balance. Background Art

[0002] Among the resplendent Chinese treasures, there was once a strange pottery called "Qi vessel". According to archaeological analysis, the Qi vessel appeared in the Stone Age about 6,000 years ago. It was found in the Banpo site as a pottery water tank with a pointed bottom, a large belly, and a small mouth. There were two loop ears for tying ropes in the middle and lower part of the belly of the water tank. Because it was originally a utensil for irrigation, when lifted by a rope, the empty tank was tilted, and water could easily enter when placed in water. When half filled with water, the water tank stood upright. When the full tank was lifted, the water tank would tilt again and pour out the water, and it would stand upright again with half of the water left. In fact, this strange property of the Qi vessel is related to the types of balance in physics. The position of the center of gravity of the whole device changed before and after adding water. When not filled with water, since the bottom was much sharper than the upper part, the whole center of gravity was above the hanging ear and was in an unstable equilibrium state. After being disturbed, the Qi vessel was generally in a tilted state. When water was added, the center of gravity returned below the hanging ear and was in a stable equilibrium state, and the Qi vessel stood upright. When filled with water, since the volume of the upper part was larger than that of the lower part, the center of gravity returned above the hanging ear again and was in an unstable equilibrium state, and it would "overflow and overturn" with a little disturbance or adding a little more water. Nowadays, the Qi vessel is widely used in our lives. Perhaps if we observe carefully, we can find that the principle of a tipping bucket for timed flushing in some toilets is that of the Qi vessel; the tipping bucket rain gauge for measuring rainfall, precipitation intensity, and start and end times of precipitation in nature also works on the principle of the Qi vessel.

[0003] However, the replicas and drawings of the Qi vessel have been lost, and the current replicas of the Qi vessel are all speculated based on some unearthed cultural relics and documentary materials. There is no relatively intuitive display device for the principle of the Qi vessel, and it is difficult for people to understand its principle from pictures and texts, resulting in less understanding of the Qi vessel by people and poor popular science effect. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above problems existing in the prior art, and provide a popular science exhibit based on the principle of object balance, which can learn the balance principle of the Qi vessel in a more intuitive way, enhance people's understanding of the Qi vessel, and thus improve the popular science effect.

[0005] To achieve the above technical purpose, the utility model is realized through the following technical solutions:

[0006] A popular science exhibit based on the principle of object balance, including a booth and a water storage tank. An installation groove is opened at the top of the booth, and the water storage tank is hermetically installed in the installation groove. A micro water pump and a controller are arranged in the booth, and the water inlet end of the micro water pump is communicated with the water storage tank through a pipeline;

[0007] A button for controlling the opening and closing of the micro water pump is also arranged on the controller, and the button is installed on the booth;

[0008] An inverted U-shaped support pipe is arranged in the water storage tank. A water outlet nozzle is opened at the closed end of the inverted U-shaped support pipe, and a water pipe is arranged in the water outlet nozzle. The other end of the water pipe is communicated with the water outlet end of the micro water pump;

[0009] An eccentric cup is arranged in the open end of the inverted U-shaped support pipe. Two lifting lugs are arranged on the outside of the eccentric cup, and lifting members are installed on the lifting lugs. The other end of the lifting member is connected to the closed end of the inverted U-shaped support pipe, and the water outlet nozzle is located between the two lifting members.

[0010] Furthermore, a glass cover is sleeved outside the water storage tank.

[0011] Furthermore, the eccentric cup is made of a transparent material.

[0012] Furthermore, the cup body of the eccentric cup is in the shape of an inverted cone.

[0013] Furthermore, the cup mouth of the eccentric cup is in the shape of a flared horn that expands outwards.

[0014] Furthermore, the water outlet of the water pipe in the water outlet nozzle points to the inside of the eccentric cup.

[0015] Furthermore, the lifting member includes a ring and a suspension rod fixedly installed at the upper end outside the ring. The other end of the suspension rod is rotatably connected to the closed end of the inverted U-shaped support pipe;

[0016] A connecting rod is rotatably installed in the ring, and the other end of the connecting rod is fixedly connected to the lifting lug on the eccentric cup.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. The present utility model provides a popular science exhibit based on the principle of object balance, which can learn the balance principle of the qi device in a more intuitive way, enhance people's understanding of the qi device, and thus improve the popular science effect.

[0019] 2. A popular science exhibit based on the principle of object balance provided by the present utility model is provided with a water storage tank, a micro water pump and a controller inside the exhibition stand. The water in the water storage tank can be pumped and transported to the water pipe through the micro water pump and flow into the eccentric cup through the water outlet nozzle. Since the cup body of the eccentric cup is in an inverted conical shape, when the water volume in the eccentric cup is different, its center of gravity position also changes continuously with the change of the water volume, causing the eccentric cup to be in a tilted, upright or overturned state, etc., so as to more intuitively display the principle of the qī qì, and improve people's understanding of the qī qì; after the eccentric cup is overturned, the water in the eccentric cup returns to the water storage tank again, thus achieving the purpose of recycling.

[0020] 3. By arranging two lifting parts in the present utility model, the eccentric cup is lifted, and then water can be injected into the eccentric cup through the water pipe. The structure is simple and suitable for actual use.

[0021] 4. The eccentric cup provided in the present utility model is made of a transparent material, so as to intuitively display the influence of the change of the water volume in the cup on the state of the eccentric cup. BRIEF DESCRIPTION OF THE DRAWINGS
