Description

Earthquake alarm

[0001] TECHNICAL FIELD The present invention relates to the field of earthquake.

[0002] BACKGROUND At present, the earthquake prediction and earthquake alarm are relatively single and backward. In 132 AD, the scientist Zhang Heng of the Eastern Han Dynasty made the world's earliest seismograph. If the earthquake occurs at night and the earthquake magnitude is high, it may cause immeasurable casualties. In 1556, the Shaanxi Huaxian earthquake in China killed about 830,000 people, in 1976, the Tangshan earthquake in China killed 242,000 people, in 2004, the Indian Ocean earthquake killed about 292,000 people, in 1920, the Haiyuan earthquake in China killed about 288,000 people, and the numbers are too numerous to mention. Seeing these numbers is shocking. At present, there is a lack of alarm device during the earthquake.

[0003] SUMMARY:In order to solve the problem of lack of alarm device in earthquake, in order to reduce casualties in earthquake, the application adopts the following two technical solutions: 1 change the nature of mechanical clock, disconnect the walk time system and the alarm time system, extend the alarm piece, place a small ball at the top of the alarm piece, when the small ball falls due to shaking, the alarm piece pops up, the alarm bell starts to work, the alarm bell of the "alarm clock" is used to remind people especially at night in earthquake. Make a colorless transparent glass (or acrylic or tempered glass or plastic or other materials) drum cylinder (or square cylinder or round cylinder or cylindrical cylinder) and cylinder cover and rubber gasket, paste night light film on the outside of the drum cylinder as scale line, paste night light film on the bottom of the outside of the drum cylinder, due to the effect of night light film, even without light at night, the water in the drum cylinder can be seen, add water in the drum cylinder, cover the cylinder cover (there can be silk between the drum cylinder and the cylinder cover, or there can be no silk, the silk is tightened), the drum cylinder is placed in a stable place, use the fluidity of water, the water in the drum cylinder will shake in earthquake, can be seen, install the mechanical clock on the colorless transparent glass (or acrylic or tempered glass or plastic) drum cylinder (or square cylinder or round cylinder or cylindrical cylinder), no matter day or night, when you hear the bell, immediately check the water in the drum cylinder, if you see the water shaking obviously, immediately run to the outdoor safety zone; 2 change the nature of mechanical clock, disconnect the walk time system and the alarm time system, extend the alarm piece, place a small ball at the top of the alarm piece, when the small ball falls due to shaking, the alarm piece pops up, the alarm bell starts to work, the alarm bell of the "alarm clock" is used to remind people especially at night in earthquake, place the mechanical clock in a stable place or on the table, make a colorless transparent glass (or acrylic or tempered glass or plastic or other materials) drum cylinder (or square cylinder or round cylinder or cylindrical cylinder) and cylinder cover and rubber gasket, add water in the drum cylinder, cover the cylinder cover (there can be silk between the drum cylinder and the cylinder cover, or there can be no silk, the silk is tightened), paste night light film on the outside of the drum cylinder as scale line, paste night light film on the bottom of the outside of the drum cylinder, due to the effect of night light film, even without light at night, the water in the drum cylinder can be seen, place the drum cylinder in a stable place or fix it on the wall (convenient for observation), use the fluidity of water, the water in the drum cylinder will shake in earthquake, can be seen. The above two technical solutions, no matter day or night, when you hear the bell, immediately check the water in the drum cylinder, if you see the water in the drum cylinder shaking obviously, immediately run to the outdoor safety zone, if you don't see the water in the drum cylinder shaking obviously, turn off the alarm bell button in time and restart the alarm bell, continue to observe the water in the drum cylinder for about 30 minutes, ensure safety, then remove the danger.The higher the earthquake level, the more the water in the drum shakes, and the more the fish, turtles, shrimps and other small animals and plants in the water in the drum are prohibited. The water in the drum should be changed every 7 days in summer, and every 7 days to 5 months in spring, autumn and winter. Due to the focusing nature, the drum containing water must be kept away from light and installed in a place not directly exposed to sunlight to avoid fire. If the response is quick, the residents on the 1st, 2nd, 3rd floors should be able to quickly move to the outdoor safety zone regardless of day or night when the earthquake occurs, to ensure personal safety and minimize casualties during the earthquake. A rechargeable flashlight should be placed beside you at night for emergency use in case of an earthquake. BRIEF DESCRIPTION OF DRAWINGS

Once a week (7 days) press the small ball (9 in Figure 2) on the top end of the alarm piece on the ground with your feet and rub it thoroughly to prevent the small ball (9 in Figure 2) from sticking to the alarm piece (8 in Figure 2) over time. Note that this technical solution and implementation do not include (not including) stainless steel teapot (13 in Figure 2) and the alarm clock extended or welded legs (12 in Figure 2) in the form of "eight"; the working principle is to fix the mechanical clockwork alarm clock, disconnect the time system and the alarm system, extend the alarm piece, place a small ball at the top end of the alarm piece, and when the small ball falls due to shaking, the alarm piece springs up, the alarm bell starts working, and the bell rings.

[0011] 【2】As shown in Figure 3, use a suitable thickness of stainless steel sheet or colorless transparent glass (or acrylic or tempered glass or plastic or fish tank or other) material with a width of about 10 cm and a length of about 40 cm, fold it at 90 degrees at one end of 10 cm (or so), then cut it 10 cm (or so) upwards according to the curvature of the alarm clock shell, cut the remaining cut into an arc with a width of 5 cm (or so) and a length corresponding to the curvature length of the above cut and the alarm clock shell, weld an alarm clock support (1 in Figure 3) according to the alarm clock shell, drill 4 holes (2 in Figure 3) at the appropriate positions of the 4 corners of the alarm clock support, drill 2 holes (3 in Figure 3) at the appropriate positions of the alarm clock support - the 2 holes correspond to the positions of the 2 legs (10 in Figure 2) of the mechanical clockwork alarm clock in (1) above.

[0012] 【3】As shown in Figure 4, take a stainless steel strip of suitable thickness, bend one end into a horizontal ring with a diameter of about 10 cm or a suitable size, then bend it downward at a 90-degree angle, with a downward length of about 10 cm, and then thread it with wire. Put a transparent mesh bag of suitable length made of fine yarn on the ring (2 in Figure 4).

[0013] 【4】As shown in Figure 5, make a colorless and transparent glass (or acrylic or tempered glass or plastic or other materials) drum (or square cylinder or round cylinder or cylindrical cylinder) (Figure 5, 1) and a cylinder cover (Figure 5, 3). Thread the joint between the drum and the cylinder cover (or leave unthreaded) to facilitate sealing. Make a suitable size and thickness of a colorless and transparent circular rubber gasket between the top of the drum opening and the cylinder cover to facilitate sealing. Drill 4 holes at appropriate positions on the cylinder cover for installing a mechanical wind-up alarm clock. The bracket (4 in Figure 5) is used to hold the drum head. A hole is drilled at a suitable position on the drum head to install a pocket bracket (8 in Figure 5) for collecting the small balls dropped from the mechanical clock. A glow-in-the-dark film is attached to the outside of the drum along the same vertical line as a graduation line (10 in Figure 5). Each graduation of the glow-in-the-dark film is approximately 4 cm long and 0.5 cm wide, with a spacing of approximately 0.4 cm between graduations. The graduation lines begin at approximately 10 cm in height and continue upwards along the same vertical line to the drum opening. The bottom outer side of the drum is completely covered with glow-in-the-dark film. Alternatively, glow-in-the-dark material can be sprayed or printed onto the drum according to the above spacing graduation lines and the bottom outer side of the drum. The drum has an opening diameter of approximately 29 cm, a belly or waist diameter of approximately 40 cm, a height of approximately 22 cm, a bottom diameter of approximately 30 cm, and a glass thickness of approximately 1 cm.

[0014] 【5】As shown in Figure 5, according to the above 【1】 and 【2】, install the mechanical clockwork alarm clock in 【1】 at the corresponding position of the bracket in 【2】. Use the original two legs of the alarm clock (10 in Figure 2) (excluding the legs extended or welded to the back of the alarm clock in Figure 2) or bolts, respectively, with washers, and pass them through the corresponding two holes on the bracket to tighten the threads (if the threads on the two legs are short, they can be lengthened to a suitable length). Install the alarm clock (5 in Figure 5) on the alarm clock bracket (4 in Figure 5). Use four bolts (11 in Figure 5) to put on one stainless steel washer and one rubber washer respectively, and pass them through the four holes on the bottom of the alarm clock bracket and the four holes corresponding to the cylinder head in 【4】 (3 in Figure 5) on the top. Put on one rubber washer and one stainless steel washer on each of the four bolts, and tighten the four bolts accordingly with four nuts. According to the above [3] and [4], put a nut, a stainless steel washer, and a rubber washer on the lower end of the stainless steel strip (8 in Figure 5), pass them through the corresponding hole of the cylinder cover (3 in Figure 5) in the above [4], put on a rubber washer, a stainless steel washer, and a nut, and tighten the two nuts to fix it. Add water (2 in Figure 5) to the cylinder (1 in Figure 5) until the cylinder height is about 10 cm, put on a circular colorless transparent rubber washer, or you can put one or several low-density luminous balls in the cylinder and float them on the water surface, put on the cylinder cover (tighten the threaded one) (3 in Figure 5), and place it in a stable place or on a table. You can also weld a bracket with stainless steel strips or stainless steel pipes, drill holes in a suitable place, and use 4 expansion bolts to install and fix the cylinder to the wall. The horizontal plane inside the cylinder is roughly level with the person's line of sight. Since the colorless transparent cylinder has a light-focusing effect after water is added, you should pay attention to avoiding light and avoid fire. Change the water in the alarm clock tank approximately every 7 days in summer, and every 7 days to 5 months in spring, autumn, and winter. In particularly cold regions, to prevent the water from freezing, a suitable amount of alcohol can be added to the water, provided it is safe to do so. During the day, when you hear the alarm clock ring, immediately check the water in the alarm clock tank. If the water is sloshing, immediately run to a safe outdoor area. At night, when you hear the alarm clock ring, immediately turn on a flashlight to check the water in the alarm clock tank. If the water is sloshing, immediately run to a safe outdoor area. If you hear the alarm clock but do not see the water sloshing, immediately turn off the alarm and restart it. Continue to observe the water in the alarm clock tank for about 30 minutes, and only discontinue the alarm when it is safe to do so. Every week (7 days), press the small ball (7 in Figure 5) on top of the alarm trigger (14 in Figure 5) onto the ground and rub it thoroughly with your foot to prevent the ball from sticking to the alarm trigger over time. The mechanical clockwork should be rung manually 1 to 7 times per week to ensure the clockwork functions properly.

[0015] Specific implementation 2: 【1】. As shown in Figure 1, Figure 2, take (or make) a mechanical clockwork alarm clock, disconnect the time system and the alarm system, drill a hole in the corresponding position of the clock holder and the shell above the alarm piece (Figure 1, 2), the size of the alarm hole (Figure 2, 7) is suitable for the movement of the alarm piece (Figure 2, 2) and the size of the alarm hole (Figure 2, 6) is equivalent, the alarm hole and the alarm hole are 1-2 mm apart, the alarm piece (Figure 1, 2) is extended or welded (the material of the alarm rod or the same material as the alarm piece or stainless steel bar or other materials with appropriate thickness) (Figure 1, 3 and Figure 2, 2) 20 cm or appropriate length, at the height of the alarm piece (Figure 2, 2) more than 2 cm (left and right) of the alarm hammer (Figure 2, 4) to the back of the alarm clock (slightly higher than the horizontal line, when the top end is placed on a small ball Figure 2, 9, it is roughly horizontal), at the end of the alarm piece 2 cm upward, at the top of the alarm piece welded a 3-100 square millimeter or area appropriate round iron sheet (iron sheet surface coated with anti-rust paint) or stainless steel round iron sheet (Figure 2, 8), put a steel ball or steel ball or metal ball or glass ball or night light ball (Figure 2, 9) on the iron sheet, the alarm clock (the alarm clock is slightly tilted when placed horizontally) (Figure 2, 1) The two legs (Figure 2, 10) are extended or lengthened or welded (the same material as the alarm clock leg) along the horizontal direction to the rear of the "eight" type 10-15 cm or appropriate length (Figure 2, 12), place a cylindrical stainless steel teapot (Figure 2, 13) with a diameter of 10 cm and a height of 5-10 cm below the steel ball (Figure 2, 9), tighten the clockwork and alarm clockwork, place the device in a stable place or on a table, and equip a flashlight next to you at night. Every week (7 days) press the ball (Figure 2, 9) at the top of the alarm piece (Figure 2, 2) on the ground with your feet to prevent the ball from sticking to the alarm piece over time. Every week, artificially let the mechanical clockwork alarm clock ring 1 to 7 times to ensure the normal work of the alarm clockwork.

[0016] [2] As shown in Figure 5, make a colorless and transparent glass (or acrylic or tempered glass or plastic or other materials) cylinder (or square cylinder or round cylinder or cylindrical cylinder) (Figure 5, 1) and a cylinder cover (Figure 5, 3). Thread the joint between the cylinder and the cylinder cover (or you can leave it unthreaded) to facilitate sealing. Make a suitable size and thickness of a circular colorless and transparent rubber gasket between the top of the cylinder opening and the cylinder cover to facilitate sealing. Attach a luminous film as a scale line on the same vertical line on the outside of the cylinder (Figure 5, 10). Each scale mark of the luminous film is about 4 cm long and 0.5 cm wide, and the interval between two scale marks is about 0.4 cm. The luminous film scale line starts from about 10 cm in height of the cylinder and follows the same vertical line from bottom to top to the cylinder opening. Cover the bottom of the outside of the cylinder with luminous film. Alternatively, luminous material can be sprayed or printed onto the scale lines and the bottom of the outside of the cylinder according to the above intervals. A glass jar (approximately 29 cm in opening diameter, 40 cm in belly or waist diameter, 22 cm in height, 30 cm in bottom diameter, and 1 cm in glass thickness) should be filled with water to about 10 cm in height. Place a circular, colorless, transparent rubber pad underneath, or one or more low-density luminous balls floating on the surface. Cover the jar with a screw-on lid and place it on a stable surface or table. Alternatively, a bracket can be welded from stainless steel strips, pipes, or angle iron and secured to a wall with four expansion bolts. The water level inside the jar should be roughly level with eye level. Because the glass (acrylic, tempered, or plastic) jar has a light-focusing effect when filled with water, it should be kept away from direct sunlight to prevent fire. Change the water in the jar approximately every 7 days in summer, and every 7 days to 5 months in spring, autumn, and winter. In extremely cold regions, to prevent the water from freezing, a small amount of alcohol can be added to the water, provided it is safe to do so. According to the above-mentioned specific implementation method 2 [1], when you hear the alarm clock ringing during the day, you should immediately check the water in the drum. If the water is shaking, you should immediately run to a safe outdoor area. When you hear the alarm clock ringing at night, you should immediately turn on the flashlight to check the water in the drum. If the water in the drum is shaking, you should immediately run to a safe outdoor area. If you hear the alarm clock but do not see the water in the drum shaking, you should turn off the alarm clock button and restart the alarm clock in time. Continue to observe the water in the drum for about 30 minutes. Only after ensuring that it is safe can the danger be eliminated. Note that in this technical solution and specific implementation method 2, holes are no longer drilled on the drum cover and alarm clocks, brackets, and stainless steel strip brackets for collecting fallen balls are no longer installed.

[0017] The night light film, the night light material and the night light ball mentioned in the application are non-toxic, harmless and non-radiation. The small ball placed on the mechanical clock is strictly prohibited to be played by children to prevent mis-swallowing and suffocation. The device should be avoided to be touched by small animals at home. The area of the round iron sheet (or stainless steel sheet) welded at the top of the alarm piece of the mechanical clock is smaller, the better the effect is when the small ball is held without falling in the static state. The term alarm clock in the application refers to the mechanical clock.

[0018] Finally, it should be noted that the above only for the preferred embodiments of the application, and not for limiting the application, although the application has been described in detail with reference to the foregoing examples, for those skilled in the art, it still can be modified to the implementation scheme recorded in the foregoing examples, or equivalent replacement of some features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application, should be included in the protection scope of the application.
