Description

Technical Field

[0001] This invention relates to the field of interactive teaching technology, specifically a big data interactive teaching and training platform. Background Technology

[0002] Interactive teaching refers to a classroom teaching model that enables interactive feedback, such as random question-and-answer sessions between teachers and students, and topical discussions or debates among students. This interactive approach can improve students' thinking skills and concentration, thereby enhancing their academic performance.

[0003] In chemistry lab classes, such as those for junior and senior high school students, teachers first explain the chemical principles to help students understand them. Then, they demonstrate the experimental steps to facilitate observation, learning, and mastery of the chemical experiments. However, some students are too far from the teacher to clearly observe the experiments, which can lead to mistakes when they try to perform the experiments themselves, potentially causing accidents and endangering their health and safety.

[0004] Students, lacking experience in chemistry experiments, are prone to making mistakes. Furthermore, their insufficient adaptability makes it difficult for them to react promptly after errors occur and to handle different incidents appropriately, potentially leading to escalating harm. For example, in chemistry experiments, alcohol lamps, commonly used in chemistry, can easily tip over when touched by students while being moved or touched by other equipment. This causes the alcohol to spill onto the table, igniting it and burning on the surface, resulting in a chemical accident. Experimental accidents can lead to injuries to students and damage to experimental equipment. For example, a fire-resistant and safe physics experimental platform disclosed in patent number CN109365027B on March 16, 2021, includes a first cabinet and a second cabinet located on one side of the first cabinet. A fixed platform is fixedly installed between the tops of the first and second cabinets on their adjacent sides. The tops of the first cabinet, the second cabinet, and the fixed platform are all at the same horizontal height. Fireproof side panels are provided on the sides of the first and second cabinets that are far apart from each other. This device improves the fireproof and flame-retardant performance of the fireproof platform panel by setting fireproof filler and fireproof coating. However, this device cannot extinguish fire sources that are already burning, such as fire sources caused by an overturned alcohol lamp.

[0005] When an alcohol lamp overturns and alcohol ignites on the table, the flow of alcohol on the table is difficult to control, causing the burning alcohol to spread irregularly and burn. Furthermore, the burning alcohol is difficult to extinguish. In chemical experiments, a damp cloth is usually used to extinguish it, but students often lack the necessary reaction time and are unable to react promptly after an alcohol lamp overturns and catches fire, leading to the fire spreading or burns to students. For example, a chemical teaching experimental platform, patent number CN107855149B, disclosed on March 31, 2020, includes a rectangular tabletop. The lower part is equipped with an equipment cabinet, and the upper part of the tabletop is equipped with a medicine cabinet, which is located at one end of the long side of the rectangular tabletop. Two parallel tracks are installed on the tabletop, with the track direction perpendicular to the long side of the tabletop. Sliding tabletops are slidably connected to the two tracks, and alcohol lamps and supports are fixedly connected to the two sliding tabletops respectively. Limit blocks are installed at the bottom of the sliding tabletops to prevent them from falling off the tracks. Red and green lights are also installed on the experimental table. This device eliminates the possibility of the alcohol lamp and support being overturned. This device cannot extinguish existing fire sources, such as fire caused by a broken alcohol lamp.

[0006] While searching for the aforementioned patents, a Chinese patent published on December 15, 2020, with patent number CN108525722B, was also found. This patent describes a multifunctional safety chemical experimental platform. The left and right movable experimental platforms are overlapped and interlocked. The left movable experimental platform is welded to the hinge of the movable platform. A locking mechanism is located on the lower surface of the fixed platform. The locking mechanism is located in a groove in the upper part of the left sandbox. A first transmission belt is fitted onto a first sandbox locking pulley and a first transmission pulley. A movable exhaust plate is located inside the fixed exhaust plate, within a movable groove in the exhaust plate. An exhaust duct connects to the exhaust port. The fixed exhaust plate is located above the fixed platform. A second transmission belt is fitted onto a second sandbox locking pulley and a second transmission pulley. This device can quickly and effectively extinguish fires in the event of an experimental fire, but it cannot prevent the generation of ignition sources, such as the tipping over of an alcohol lamp.

[0007] In view of this, the present invention provides a big data interactive teaching and training platform that can fix an alcohol lamp to prevent the generation of a fire source and extinguish a fire source generated after the alcohol lamp is overturned. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a big data interactive teaching and training platform to solve the issues that existing chemical laboratory benches cannot clamp and fix alcohol lamps or extinguish the fire generated by alcohol lamps.

[0009] This invention provides the following technical solution: a big data interactive teaching and training platform, including an experimental table for users to conduct chemical experiments. The experimental table consists of a tabletop and a table body. The tabletop is fixedly installed on top of the table body, and users conduct chemical experiments on the tabletop. The table body is used to store chemical supplies. A protective device is installed above the tabletop to prevent users from making mistakes during chemical experiments, which could cause the alcohol lamp to tip over or be damaged, leading to an experimental fire. The protective device includes a moving unit, a protective unit, and a clamping unit. The moving unit is slidably installed on the tabletop along the length of the experimental table. The moving unit is used to support and move the protective device, thereby facilitating users to adjust the position of the alcohol lamp during chemical experiments. A protective unit is installed at the center of the surface. This unit is used to seal the protective device, thus isolating the alcohol lamp from oxygen and extinguishing the fire if it is overturned or damaged. It also prevents users from being burned by flames in the event of a fire caused by experimental errors. A clamping unit is fixedly installed on the upper surface of the protective unit. This clamping unit is used to hold the alcohol lamp in place, preventing users from accidentally overturning the alcohol lamp during chemical experiments and thus preventing the alcohol lamp from overturning and causing a fire on the experimental table. The cooperation between the moving unit and the protective unit allows for flexible adjustment of the alcohol lamp while preventing alcohol from flowing onto the experimental table surface and spreading the fire source after the alcohol lamp is overturned or damaged. Furthermore, the cooperation between the moving unit and the clamping unit can clamp and fix the alcohol lamp when adjusting its position to prevent it from overturning and causing a fire.

[0010] The moving unit includes a slide groove and a base. The slide groove is parallel to the length of the experimental platform, and the base is slidably installed within the slide groove. The lower surface of the base is provided with a protrusion that mates with the slide groove. It should be noted that the protrusion mates with the slide groove, thereby making the lower surface of the base fit snugly against the upper surface of the experimental platform, which helps to increase the stability of the base and further prevent the alcohol lamp from tipping over. Through the interaction of the base and the slide groove, the alcohol lamp can be moved relative to the upper surface of the experimental platform, which is beneficial for users to change the position of the alcohol lamp according to different chemical experiments. When moving the alcohol lamp, the user's hand comes into contact with the base, thereby changing the position of the alcohol lamp on the upper surface of the experimental platform by pushing the base.

[0011] A vertical wall is fixedly installed above the base to cooperate with the protection unit. The vertical wall can prevent alcohol from flowing onto the table and thus spreading the fire source when the alcohol lamp is damaged or overturned during the user's chemical experiment. When the alcohol lamp is overturned or damaged, the alcohol flows downward from the clamping unit that holds the alcohol lamp to the base. When the alcohol flows to the base, it diffuses outward from the base and comes into contact with the vertical wall, thereby accumulating the alcohol on the upper surface of the base through the vertical wall.

[0012] The clamping unit includes a base plate and a clamping sleeve. The base plate is fixedly mounted above the support column, and the bottom of the clamping sleeve is hinged to the top of the base plate. Multiple clamping sleeves are arranged in an array along the axis of the support column. The multiple clamping sleeves can rotate around the hinge point. It should be noted that when the clamping sleeve rotates, its edge contacts the base plate, so that the clamping sleeve can only rotate at a small angle, preventing the clamping sleeve from detaching from the upper surface of the base plate during rotation. When placing an alcohol lamp, the user places the alcohol lamp in the clamping sleeve above the base plate, so that the alcohol lamp contacts the bottom of the clamping sleeve. At the same time, the bottom of the clamping sleeve is subjected to the gravity of the alcohol lamp, so that the clamping sleeve rotates around the hinge point with the base plate, thereby making the clamping sleeve perpendicular to the alcohol lamp and completing the clamping of the alcohol lamp, preventing the alcohol lamp from tipping over due to shaking.

[0013] The protection unit includes a support column, a first fixing rod, a fireproof cloth, a sliding sleeve, a second fixing rod, and a telescopic rod. The support column is fixedly installed at the center of the upper surface of the base. A first fixing rod is hinged to the surface of the support column and near the end of the base. Multiple first fixing rods are arranged in a circumferential array along the axis of the support column. A fireproof cloth is fixedly installed on the lower surface of the first fixing rod by adhesive. A sliding sleeve is slidably installed on the surface of the support column and above the first fixing rod. One end of the second fixing rod is hinged to the outer surface of the sliding sleeve, and the other end of the second fixing rod is hinged to the center of the upper surface of the first fixing rod. A telescopic rod is fixedly installed above the sliding sleeve, and the other end of the telescopic rod is fixedly installed to the clamping unit.

[0014] The work surface is fixedly equipped with an interactive unit, which includes a monitor and a camera. The monitor is fixedly installed above the work surface and is used to display the teacher's chemical experiment process, making it convenient for users to observe the teacher's steps during the experiment. This avoids situations where users are too far from the teacher or have poor eyesight and cannot clearly see the experimental process, further preventing errors caused by users not being able to clearly see the teacher's chemical experiment. This further ensures the safety of users during chemical experiments. At the same time, clearly viewing the teacher's experimental process through the monitor facilitates classroom Q&A and increases interaction between teachers and students. The monitor is tilted relative to the work surface, which makes it easier for students to view the experiment.

[0015] A camera is fixedly installed on the side of the display. The camera is used to monitor the students' experimental process and analyze the data to prevent students from making mistakes during the chemistry experiment, thereby further improving the safety of students when conducting chemistry experiments. If the students make mistakes or errors in the experimental steps, the camera can analyze and identify them through big data, and at the same time transmit the electrical signal to the teacher through the data processing center for early warning.

[0016] A spring is fixedly installed at the bottom of the clamping sleeve, and the other end of the spring is fixedly installed above the substrate. When the alcohol lamp is removed, the spring can help the clamping sleeve rotate around the hinge point with the substrate as the axis, thereby making it convenient for the user to remove the alcohol lamp.

[0017] The base is circular, which allows alcohol to flow stably onto the base when the alcohol lamp is overturned or damaged, preventing it from flowing onto the table surface. The circular structure also allows for greater alcohol capacity, improving the base's stability when receiving alcohol. The vertical wall is fixedly arranged in a ring along the edge of the base. This ring-shaped arrangement prevents alcohol from flowing onto the table surface, thus preventing the spread of fire. The fireproof cloth is also circular and fits snugly against the base. When unfolded, the fireproof cloth adheres closely to the base, ensuring its integrity.

[0018] The inner surface of the base is inclined, and the lowest point of the horizontal line is at the center of the inner surface of the base, which is inclined towards the end of the supporting column. When the base receives alcohol, the alcohol will converge at the center position, i.e., the lowest point of the horizontal line, which further prevents the spread of fire caused by the alcohol flowing to the table surface. This further ensures the safety of users in case of accidental spillage or damage to alcohol during chemical experiments.

[0019] The inner wall of the top of the clamping sleeve is inclined, which makes it easy for the user to remove the alcohol lamp. When removing the alcohol lamp, the user picks up the alcohol lamp and separates the alcohol lamp from the bottom of the clamping sleeve. At the same time, the alcohol lamp contacts the top of the clamping sleeve. The top of the inclined structure contacts the alcohol lamp and is subjected to force, thereby rotating around the hinge point between the clamping sleeve and the substrate.

[0020] The fireproof cloth is made of basalt fiber fireproof cloth or high silica fireproof cloth. Basalt fiber fireproof cloth is resistant to high temperature and chemical corrosion. This prevents the fireproof cloth from coming into contact with corrosive solutions during chemical experiments when it is isolated from alcohol leaking out after the alcohol lamp is damaged or overturned. This avoids the fireproof cloth from being corroded and thus prevents the fireproof cloth from failing due to corrosion.

[0021] The beneficial effects that this invention can achieve through the above technical solutions are as follows:

[0022] 1. This invention utilizes a design that combines a clamping unit and a moving unit. The clamping unit can hold and fix the alcohol lamp while it is being placed, thus preventing the lamp from tipping over during the experiment and avoiding any potential fire source. The moving unit allows for adjustment of the alcohol lamp's position while it is being held in place by the clamping unit, facilitating changes to the lamp's position during the experiment.

[0023] 2. This invention employs a design that integrates a protection unit and a moving unit. After the alcohol lamp is damaged, the alcohol flows to the upper surface of the base and accumulates there due to the action of the vertical wall. The extension of the telescopic rod moves the sliding sleeve and the second fixed rod, thereby allowing the first fixed rod and the fireproof cloth to unfold and isolate the alcohol on the base surface. This extinguishes the burning alcohol while preventing the user from being burned by the flame, and also prevents the burning alcohol from flowing onto the table and damaging the experimental equipment.

Detailed Implementation

[0036] To facilitate understanding by those skilled in the art, the technical solution of the present invention will be explained in detail below.

[0037] Example 1: As Figures 1 to 3 , Figure 7 , Figure 8 and Figure 10 As shown, this embodiment describes a chemistry experiment class, specifically a chemistry experiment class for high school students. The embodiment focuses on preventing the alcohol lamp from malfunctioning and creating a fire source during the experiment. It should be noted that high school students have more experience in chemistry experiments and make fewer mistakes during the experiment. Therefore, this embodiment is specifically applicable to high school experiment classes. It uses a black bullet camera 52 with 12V wired power supply and an 8-inch monitor 51.

[0038] A big data interactive teaching and training platform includes an experimental table 1 for users to conduct chemical experiments. The experimental table 1 consists of a tabletop 11 and a table body 12. The tabletop 11 is fixedly installed on top of the table body 12. Users conduct chemical experiments on the upper surface of the tabletop 11. The table body 12 is used to store chemical supplies. A protective device is installed above the tabletop 11 to prevent users from making mistakes during chemical experiments, such as tipping over or damaging the alcohol lamp, which could lead to an accidental fire. The protective device includes a moving unit 2, a protective unit 3, a clamping unit 4, and an interactive unit 5. The moving unit 2 is slidably installed on the upper surface of the tabletop 11 along the length of the experimental table. The moving unit 2 is used to support and move the protective device, thereby facilitating users to adjust the position of the alcohol lamp during chemical experiments. The protective unit 3 is installed at the center of the upper surface of the moving unit 2. The protective unit 3 is used to seal the protective device, thereby isolating oxygen to extinguish the fire after the alcohol lamp is overturned or damaged, and preventing burns to personnel in case of fire caused by experimental errors. A clamping unit 4 is fixedly installed on the upper surface of the protective unit 3. The clamping unit 4 is used to hold the alcohol lamp in place, thereby preventing the alcohol lamp from overturning due to user error during chemical experiments, and thus preventing the alcohol lamp from overturning and causing a fire on the experimental table 1. An interactive unit 5 is fixedly installed above the table 11, which is used for interaction between teachers and students. Through the cooperation of the moving unit 2 and the protective unit 3, the alcohol lamp can be flexibly adjusted while preventing the alcohol from flowing onto the surface of the experimental table 1 after the alcohol lamp is overturned or damaged, thus preventing the fire source from spreading. Furthermore, the cooperation of the moving unit 2 and the clamping unit 4 can clamp and fix the alcohol lamp when adjusting its position to prevent fire caused by overturning.

[0039] The moving unit 2 includes a slide 21 and a base 22. The slide 21 is parallel to the length of the experimental table 1 on the table surface 11. The base 22 is slidably installed in the slide 21. The lower surface of the base 22 is provided with a protrusion that cooperates with the slide 21. It should be noted that the protrusion cooperates with the slide 21, so that the lower surface of the base 22 is in contact with the upper surface of the experimental table 1, which helps to increase the stability of the base 22 and further prevent the alcohol lamp from tipping over. Through the cooperation of the base 22 and the slide 21, the alcohol lamp can be moved relative to the upper surface of the experimental table 1, which is beneficial for the user to change the position of the alcohol lamp according to different chemical experiments. When moving the alcohol lamp, the user's hand comes into contact with the base 22, thereby changing the position of the alcohol lamp on the upper surface of the experimental table 1 by pushing the base 22.

[0040] A vertical wall 221, which cooperates with the protection unit 3, is fixedly installed above the base 22. The vertical wall 221 prevents alcohol from flowing onto the table and thus spreading the fire source when the alcohol lamp is damaged or overturned during a chemical experiment. The cooperation between the vertical wall 221 and the protection unit 3 ensures the safety of the user during chemical experiments. When the alcohol lamp is overturned or damaged, the alcohol flows downward from the clamping unit 4 that holds the alcohol lamp to the base 22. When the alcohol flowing to the base 22 diffuses outward from the base 22, it comes into contact with the vertical wall 221. Thus, the vertical wall 221 causes the alcohol to accumulate on the upper surface of the base 22, preventing the alcohol from flowing onto the table and spreading the fire source due to the user's mistake in damaging or overturning the alcohol lamp during a chemical experiment.

[0041] The protection unit 3 includes a support column 31, which is fixedly installed at the center of the upper surface of the base 22. The clamping unit 4 includes a base plate 42 and a clamping sleeve 41. The base plate 42 is fixedly installed above the support column 31, and the bottom of the clamping sleeve 41 is hinged to the top of the base plate 42. Multiple clamping sleeves 41 are arranged in an array along the axis of the support column 31, and the multiple clamping sleeves 41 can rotate about the hinge point. It should be noted that when the clamping sleeve 41 rotates, its edge contacts the base plate 42, thereby clamping... The sleeve 41 can only rotate at a small angle to prevent it from detaching from the upper surface of the substrate 42 during rotation. When placing the alcohol lamp, the user places the alcohol lamp in the sleeve 41 above the substrate 42, so that the alcohol lamp contacts the bottom of the sleeve 41. At the same time, the bottom of the sleeve 41 is subjected to the gravity of the alcohol lamp, so that the sleeve 41 rotates around the hinge point with the substrate 42, thereby making the sleeve 41 perpendicular to the alcohol lamp and completing the clamping of the alcohol lamp, preventing the alcohol lamp from tipping over due to shaking.

[0042] When removing the alcohol lamp, the user lifts the lamp and moves it. At this time, the bottom of the clamping sleeve 41 disengages from the lamp, while the top of the clamping sleeve 41 contacts the lamp and rotates around the hinge point with the substrate 42. This causes the clamping sleeve 41 to open to both sides, meaning the top gap of the clamping sleeve 41 is greater than the bottom gap. The user can then remove the alcohol lamp from inside the clamping sleeve. Through the cooperation between the clamping sleeve and the substrate 42, the user can clamp the alcohol lamp by rotating the clamping sleeve 41 around the hinge point while placing the lamp, thus preventing the lamp from tipping over or being damaged due to user error during chemical experiments.

[0043] An interactive unit 5 is fixedly installed on the tabletop 11. The interactive unit 5 includes a display 51 and a camera 52. The display 51 is fixedly installed above the tabletop 11 and is used to display the teacher's chemical experiment process. This allows users to easily observe the steps the teacher takes during the experiment, avoiding the inability of users who are too far from the teacher or have poor eyesight to clearly see the experimental process. This further prevents errors caused by users not being able to clearly see the teacher's chemical experiment, and further ensures the safety of users during chemical experiments. At the same time, clearly viewing the teacher's experimental process through the display 51 facilitates classroom Q&A and increases interaction between teachers and students. The display 51 is tilted relative to the tabletop 11, which makes it easier for students to view.

[0044] A camera 52 is fixedly installed on the side of the display 51. The camera 52 is used to monitor the students' experimental process and analyze it through big data, thereby preventing students from making mistakes during the chemical experiments and further improving the safety of students when conducting chemical experiments. If the students make mistakes or errors in the experimental steps during the experiment, the camera 52 can analyze and identify them through big data, and at the same time transmit the electrical signal to the teacher's end through the data processing center for early warning, thereby preventing the danger caused by the user's mistakes during the chemical experiments and further improving the safety of the user when conducting chemical experiments.

[0045] A spring is fixedly installed at the bottom of the clamping sleeve 41, and the other end of the spring is fixedly installed above the substrate 42. When the alcohol lamp is removed, the spring helps the clamping sleeve 41 to rotate around the hinge point with the substrate 42, thus facilitating the user to remove the alcohol lamp. When removing the alcohol lamp, the user lifts the alcohol lamp, and the bottom of the alcohol lamp disengages from the bottom of the clamping sleeve 41. At the same time, the clamping sleeve 41 is forced upward by the spring fixedly installed at the bottom and rotates around the hinge point with the substrate 42, so that the clamping sleeve 41 is in an open state, that is, the distance at the top of the clamping sleeve 41 is greater than the distance at the bottom, thus facilitating the user to directly remove the alcohol lamp and avoiding the alcohol lamp and the top of the clamping sleeve 41 from getting stuck together when removing the alcohol lamp.

[0046] The base 22 has a circular structure. This circular structure allows alcohol to flow stably to the base 22 when the alcohol lamp is overturned or damaged, preventing alcohol from flowing onto the tabletop 11. Furthermore, the circular structure can hold more alcohol, improving the stability of the base 22 when receiving alcohol. The vertical wall 221 is fixedly arranged in a ring along the edge of the base 22. This ring-fixed arrangement prevents alcohol from flowing onto the tabletop 11 when the base 22 receives alcohol, thus preventing the spread of fire. The fireproof cloth 33 has a circular structure and cooperates with the base 22. After unfolding, the fireproof cloth 33 adheres to the base 22, thus ensuring the fireproof cloth 33...

[0047] The inner surface of the base 22 is inclined, and the lowest point of the horizontal line is at the center of the inner surface of the base 22 towards the end of the supporting column 31. The inclined structure of the inner surface of the base 22 can cause the alcohol to converge along the center position, i.e., the lowest point of the horizontal line, when receiving alcohol, further preventing the spread of fire caused by the alcohol flowing to the table 11, and further ensuring the safety of users in case of accidental spillage or damage of alcohol during chemical experiments.

[0048] The inner wall of the top of the clamping sleeve 41 is inclined, which facilitates the user's removal of the alcohol lamp. When removing the alcohol lamp, the user picks up the alcohol lamp and disengages it from the bottom of the clamping sleeve 41, while the alcohol lamp contacts the top of the clamping sleeve 41. The top of the inclined structure is in contact with the alcohol lamp and is subjected to force, thus rotating around the hinge point between the clamping sleeve 41 and the base plate 42, thereby opening up the clamping sleeve 41 so that the gap at the top is greater than the gap at the bottom, making it convenient for the user to remove the alcohol lamp after use. It should be noted that a gap is provided between the top of the clamping sleeve 41 and the alcohol lamp. The gap is designed to prevent the alcohol lamp from getting stuck in the clamping sleeve 41 when removing the alcohol lamp, thus making it convenient for the user to remove the alcohol lamp.

[0049] Example 2: Based on the above examples, such as... Figures 1 to 6 , Figure 9 and Figure 10 As shown, this embodiment is for a chemistry experiment class, specifically illustrating the fire source generated after an alcohol lamp is damaged due to an experimental error. This embodiment is for a chemistry experiment class for junior high school students. It should be noted that junior high school students have more experience in chemistry experiments and make more mistakes in the experimental process. Therefore, this embodiment is specifically applicable to junior high school experiment classes. It uses a black gun-type camera 52 with 12V wired power supply, an 8-inch monitor 51, and basalt fiber fireproof cloth 33.

[0050] The protection unit 3 includes a support column 31, a first fixing rod 32, a fireproof cloth 33, a sliding sleeve 34, a second fixing rod 35, and a telescopic rod 36. The support column 31 is fixedly installed at the center of the upper surface of the base 22. The first fixing rod 32 is hinged to the surface of the support column 31 and near the end of the base 22. Multiple first fixing rods 32 are arranged in a circumferential array along the axis of the support column 31. The fireproof cloth 33 is fixedly installed on the lower surface of the first fixing rod 32 by adhesive. The sliding sleeve 34 is slidably installed on the surface of the support column 31 and above the first fixing rod 32. One end of the second fixing rod 35 is hinged to the outer surface of the sliding sleeve 34, and the other end of the second fixing rod 35 is hinged to the center of the upper surface of the first fixing rod 32. The telescopic rod 36 is fixedly installed above the sliding sleeve 34, and the other end of the telescopic rod 36 is fixedly installed to the clamping unit 4.

[0051] The extension of the telescopic rod 36 causes the sliding sleeve 34 to slide up and down on the surface of the first fixed rod 32, thereby causing the hinge point between the second fixed rod 35 and the sliding sleeve 34 to slide up and down along the surface of the bearing column 31 along with the sliding sleeve 34. When the second fixed rod 35 slides up and down at the hinge point between the second fixed rod 35 and the sliding sleeve 34, the first fixed rod 32 is pulled by the second fixed rod 35 at the hinge point of the second fixed rod 35, thereby causing the first fixed rod 32 to rotate along the hinge point between the first fixed rod 32 and the bearing column 31, thereby causing the fireproof cloth 33 fixedly bonded to the bottom of the first fixed rod 32 to unfold or tighten. It should be noted that when the telescopic rod 36 retracts to the stop point away from the base 22, the first fixed rod 32 The fireproof cloth 33 is bound together by the support column 31. When the telescopic rod 36 extends to the stop point near the base 22, the first fixing rod 32 unfolds parallel to the base 22, thereby unfolding the fireproof cloth 33 to adhere to the vertical wall 221. The base 22 is then closed by the unfolding of the fireproof cloth 33. It should be noted again that the fireproof cloth 33 is not hygroscopic. When the fireproof cloth 33 is unfolded to adhere to the vertical wall 221, the horizontal height of the fireproof cloth 33 should be slightly lower than the vertical wall 221. This way, when the alcohol lamp is overturned and the alcohol is left on the surface of the base 22 and is isolated by the fireproof cloth 33, the alcohol lamp will be damaged a second time, causing the remaining alcohol to flow out again. The alcohol that flows out again can accumulate on the surface of the fireproof cloth 33 to prevent it from flowing onto the table and thus avoid damaging the experimental equipment.

[0052] Through the cooperation of the first fixing rod 32, the sliding sleeve 34, the second fixing rod 35, and the fireproof cloth 33, when the alcohol lamp is damaged or overturned due to user error during a chemical experiment and the alcohol flows to the base 22, the fireproof cloth 33 is unfolded by the first fixing rod 32 and adheres to the vertical wall 221, thereby sealing the base 22 and preventing the alcohol on the upper surface of the base 22 from contacting oxygen, thus extinguishing the burning alcohol. Furthermore, the fireproof cloth 33, while isolating oxygen to extinguish the burning alcohol, also prevents the flame from burning the user, ensuring user safety and preventing the burning alcohol from flowing to the table and damaging experimental equipment, thus reducing losses caused by experimental errors. It should be noted that the tabletop 11 is equipped with a control button (not shown in the figure) for controlling the extension or retraction of the telescopic rod 36, thereby controlling the unfolding or tightening of the fireproof cloth 33.

[0053] The fireproof cloth 33 is made of basalt fiber fireproof cloth 33. Basalt fiber fireproof cloth 33 is resistant to high temperature and chemical corrosion. This allows the fireproof cloth 33 to prevent the alcohol from leaking out after the alcohol lamp is damaged or overturned. It also prevents the fireproof cloth 33 from coming into contact with corrosive solutions during chemical experiments, thus avoiding the failure of fireproof performance caused by corrosion. This further ensures that the fireproof cloth 33 can still be used normally when the alcohol lamp is overturned or damaged due to the user's mistake during chemical experiments, which is conducive to ensuring the safety of the user.

[0054] During chemical experiments, the user first moves the base 22 to the designated position via the slide 21. At this time, the clamping sleeve 41 is open due to the action of the bottom spring, that is, the top gap of the clamping sleeve 41 is greater than the bottom gap. Then, the alcohol lamp is placed with the top of the clamping sleeve 41 facing down and inside the clamping sleeve 41. When the alcohol lamp is placed inside the clamping sleeve 41, the alcohol lamp contacts the bottom of the clamping sleeve 41 and applies pressure, so that the clamping sleeve 41 rotates around the hinge point with the base plate 42 as the axis and completes the clamping of the alcohol lamp, thereby preventing the alcohol lamp from tipping over during the chemical experiment.

[0055] After clamping the alcohol lamp, the user begins a chemical experiment. If the alcohol lamp is damaged due to an error during the experiment, alcohol flows from inside the lamp to the outside, i.e., the surface of the substrate 42. Then, the alcohol flows from the surface of the substrate 42 to the surface of the base 22, and accumulates on the upper surface of the base 22 under the action of the vertical wall 221. The user then activates the control button to extend the telescopic rod 36. The extension of the rod causes the sliding sleeve 34 to slide downwards on the surface of the first fixed rod 32, thereby causing the second fixed rod 35 to engage with the sliding sleeve 34. The hinged joint slides up and down along the surface of the bearing column 31 with the sliding sleeve 34, and the first fixing rod 32 is pulled by the second fixing rod 35 at the hinged joint of the first fixing rod 32 and the bearing column 31, thereby causing the first fixing rod 32 to rotate downward along the hinged joint of the first fixing rod 32 and the bearing column 31, thereby causing the fireproof cloth 33 fixed and bonded to the bottom of the first fixing rod 32 to unfold and adhere to the vertical wall 221. After the fireproof cloth 33 adheres to the vertical wall 221, it completes the sealing of the alcohol in the base 22 and isolates oxygen for fire extinguishing, while preventing flames from burning the user.

[0056] When removing the alcohol lamp, the user lifts the lamp, and the bottom of the lamp disengages from the bottom of the clamping sleeve 41. At the same time, the clamping sleeve 41 is subjected to upward force by the spring fixed at the bottom and rotates around the hinge point with the base plate 42, so that the clamping sleeve 41 is in an open state, that is, the distance at the top of the clamping sleeve 41 is greater than the distance at the bottom, which makes it convenient for the user to remove the alcohol lamp directly and avoids the alcohol lamp and the top of the clamping sleeve 41 getting stuck together when removing the alcohol lamp.

[0057] The present invention is described using only the above embodiments, but the structure, arrangement, and connection relationships of the various components of the present invention can be changed accordingly.
