Description

Technical Field

[0001] The invention relates to the technical field of geography teaching demonstration devices, and in particular to a convective weather simulation device for geography teaching. Background Art

[0002] Convective weather is a common weather phenomenon. The hotter air near the ground rises under the action of buoyancy and forms an ascending hot and humid air flow. When it rises to a certain height and the temperature drops, the water vapor in the air condenses into water droplets. When the water droplets fall, they are carried up by stronger updrafts. This process repeats continuously, and small water droplets begin to accumulate into large water droplets until the high-altitude air flow is unable to support their weight, and finally they fall as rain.

[0003] Convective weather is an important knowledge point in the geography teaching process, but due to the lack of demonstration teaching aids, students can only understand it through books and teachers' explanations, which leads to many students' inability to quickly and deeply understand this knowledge point. After searching, the Chinese patent publication number CN202110703U discloses an air convection experimental device, but the device only shows the flow of airflow, and does not show the formation of rain, and the simulation effect is poor. Summary of the invention

[0004] Based on the technical problem that the simulation effect of convective weather demonstration teaching aids in geography teaching is poor and affects the teaching effect, the present invention proposes a convective weather simulation device for geography teaching.

[0005] The present invention proposes a convective weather simulation device for geography teaching, comprising a heating box, an airflow box is fixed to the top outer wall of the heating box by screws, and a transparent cover is fixed to the top of one side outer wall of the heating box by screws, an air supply pipe plug hole is opened at the bottom of one side outer wall of the airflow box and one side outer wall of the heating box, and the inner walls of the two air supply pipe plug holes are both plugged with the same air supply pipe, a heating pipe and a blower are respectively fixed to the bottom inner wall and one side outer wall of the heating box by screws, and the air outlet end of the blower is plugged into the inner wall of one end of the air supply pipe, and one side outer wall of the heating box A return pipe jack is provided at the top of the wall and at the bottom of the outer wall on one side of the transparent cover, and the same return pipe is inserted into the inner walls of the two return pipe jacks, a one-way valve is clamped on the outer wall on one side of the return pipe through a clamp, a sealing plate is welded to the bottom inner wall of the airflow box, and the bottom of the outer wall on one side of the sealing plate is sleeved on the inner wall on one side of the heating box, the top outer wall of the transparent cover is fixed with a cooling box by screws, and thermal conductive plate installation grooves are provided on both sides of the bottom outer wall of the cooling box, and the inner walls of the two thermal conductive plate installation grooves are sleeved with sealing rings, and the inner walls of the two sealing rings are sleeved with thermal conductive plates.

[0006] Preferably, the air supply pipe consists of a spiral pipe and a straight pipe, and the spiral pipe is located inside the heating box.

[0007] Preferably, an air outlet pipe plug hole is opened on the top outer wall of the air flow box, and an air outlet pipe is plugged into the inner wall of the air outlet pipe plug hole, and the air flow box is a hollow ellipsoid structure.

[0008] Preferably, a support spring is welded to the top of the inner wall of one side of the air outlet pipe, and a stopper is welded to the top outer wall of the support spring, and the stopper is a gyro-shaped structure.

[0009] Preferably, one inner wall of the airflow box is connected to a guide plate via a hinge, and the guide plate is a J-shaped structure.

[0010] Preferably, a steam hole is opened on the bottom inner wall of the sealing plate, a return spring is welded to the top inner wall of the steam hole, and a sealing plug is welded to the top outer wall of the return spring.

[0011] Preferably, one side outer wall of the two thermal conductive plates is provided with a condensation plate groove, and the inner walls of the two condensation plate grooves are slidably connected to the same condensation plate, and vibration springs are welded on both sides of the bottom outer wall of the condensation plate and the bottom inner walls of the two condensation plate grooves.

[0012] Preferably, a condensation protrusion is welded to the bottom outer wall of the condensation plate, and the condensation protrusion is an inverted cone structure.

[0013] Preferably, the transparent cover comprises a hollow cylindrical structure and an inverted hollow conical structure.

[0014] Preferably, a semiconductor refrigeration plate is fixed to the bottom inner wall of the cooling box by screws, and the semiconductor refrigeration plate, the heating tube and the blower are all connected to a switch through wires, and the switch is connected to a power source through wires.

[0015] The beneficial effects of the present invention are:

[0016] 1. The convective weather simulation device for geography teaching can guide the hot air inside the air supply pipe to flow toward the bottom inner wall of the air flow box through the J-shaped guide plate, so that the air flow is fully in contact with the steam, which helps to increase the humidity of the air flow, provides a guarantee for the formation of rain in the later period, and is beneficial to improving the simulation effect. At the same time, when the air flow flows to the top outer wall of the guide plate, the J-shaped structure can guide the air flow to flow toward the top of the air flow box, which helps to prevent the air flow at the top of the air flow box from repeatedly flowing downward and affecting the air outlet rate.

[0017] 2. The convective weather simulation device for geography teaching has a condensation plate, a vibration spring and a condensation protrusion. When the airflow blows on the condensation plate, the vibration spring is stretched, which can reduce the impact of the wind on the condensation plate, help reduce the deformation of the condensation plate to extend the service life of the condensation plate, and at the same time, as the wind force changes, the vibration spring drives the condensation plate to vibrate, which can accelerate the falling of water droplets on the condensation plate. The condensation protrusion with an inverted cone structure set on the bottom outer wall of the condensation plate can also accelerate the falling of water droplets, which helps to improve the phenomenon that water accumulates in large quantities on the bottom outer wall of the condensation plate and then directly falls, affecting the simulation effect and condensation effect.

[0018] 3. The convective weather simulation device for geography teaching has a block and a support spring. When the airflow flows out through the air outlet pipe, it pushes the block to stretch the support spring. The block with a gyro-shaped structure can reduce the resistance to the airflow and keep the air outlet unobstructed. At the same time, the gyro-shaped structure can guide the water droplets falling on the block to flow to both sides, which helps to prevent the water droplets from falling into the outlet pipe and cooling the hot air flow prematurely, thereby affecting the simulation effect.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The present invention has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the present invention, the air supply pipe 10 is composed of a spiral pipe and a straight pipe, and the spiral pipe is located inside the heating box 1. The spiral pipe can prolong the flow time of the airflow inside the heating box 1, which helps to ensure that the gas is fully heated.

[0030] In the present invention, an air outlet duct hole is opened on the top outer wall of the air flow box 4, and an air outlet duct 17 is inserted into the inner wall of the air outlet duct hole. The air flow box 4 is a hollow ellipsoidal structure. The ellipsoidal structure facilitates the water flow down from the top outer wall of the air flow box 4, which can improve the phenomenon of water accumulation on the top of the air flow box and help reduce the phenomenon of condensed water droplets affecting the air flow temperature.

[0031] In the present invention, a support spring 18 is welded to the top of the inner wall of one side of the air outlet pipe 17, and a block 19 is welded to the top outer wall of the support spring 18. The block 19 is a gyro-shaped structure. The airflow pushes the block 19 to stretch the support spring 18. The gyro-shaped block 19 can prevent water droplets from falling into the air outlet pipe 17 while maintaining smooth air outlet.

[0032] In the present invention, a guide plate 15 is connected to the inner wall of one side of the airflow box 4 through a hinge, and the guide plate 15 is a J-shaped structure. The J-shaped guide plate 15 can guide the hot air inside the air supply pipe 10 to flow toward the bottom inner wall of the airflow box 4, so as to facilitate the control of the flow direction of the airflow.

[0036] In the present invention, the transparent cover 5 includes a hollow cylindrical structure and an inverted hollow conical structure.

[0038] When in use, turn on the heating tube 9 and the semiconductor refrigeration sheet 12, start the blower 2 to supply air to the air supply pipe 10, the air flow inside the air supply pipe 10 is heated inside the heating box 1 and then enters the air flow box 4, and at the same time, the steam inside the heating box 1 pushes the sealing plug 22 to stretch the reset spring 21, and the steam enters the air flow box 4 through the steam hole 20, and the heated air flow carries the steam into the air outlet pipe 17, and the air flow pushes the block 19 to stretch the support spring 18 to flow out into the transparent cover 5, and the thermal conductive sheet 8 transfers the heat inside the transparent cover 5 to the cooling box 7 to cool the hot air flow. As the hot air flow continues to rise, the temperature gradually decreases, and the steam in the air flow condenses into water droplets and falls, while the hot air flow continuously gushes out from the air outlet pipe 17 to drive the water droplets to rise, and this process is repeated, the water droplets gather and increase, and after the hot air flow cannot carry the water droplets up, the water droplets fall to form rainfall.
