- The present invention is an earthquake alarm device. By analyzing the vibration type of an earthquake, the present invention mainly including two sub systems, namely the vertical vibration detecting system and the horizontal swinging (or vibration) detecting system. When an earthquake occurs, this invention can independently detect the vibration type and the amplitude thereof. Then, it will independently activate the related alarms. Therefore, it can provide a warning at a crucial moment for escape. Also, the people can immediately know the information about the vibration type of the earthquake.
- More specifically, this invention's structure comprises the following three portions:
- (1) housing (as shown in FIG. 1): The function of the
housing 1 is to provide a space to contain all the related structures and elements, such as a charger, a battery, an alarm set, light, etc. And, after installation at palace, a positioning system will be automatically positioning to a normal condition. - (2) horizontal swinging detecting system (as shown in FIG. 2): It is mainly composed by a
fixing tube 2 and related detecting elements. Its main function is to detecting the information about the horizontal vibration. - (3) vertical vibration detecting system (as shown in FIG. 2): It is mainly composed by a detecting
tube 3 and related detecting elements. Its main function is to receive the information of the vertical vibration. - Referring to FIGS. 2 and 3, the detailed structure of this invention is described as follows.
- A
housing 1 is disposed. Its upper end has alocking knob seat 12 with a hole. This hole has an inner thread for engaging with a fixingtube locking knob 11 that has an outer thread. By means of a spherical recess on the bottom of the fixingtube locking knob 11, a horizontalsliding ball 13 can be quickly and firmly locked. This makes thefixing tube 2 and the detectingtube 3 towards down to the center of the earth. Thus, it will not be affected by the horizontal condition of the ground where this invention is installed (as shown in FIG. 4). In order to make sure the tilted condition at the place after installed, a tilted angle θ is formed under this 3-demensional condition between a central axis of thehousing 1 an the axis of thefixing tube 2 and detecting tube 3 (towards to the center of the earth). The horizontalsliding ball 13 is disposed on a spherical recess of thehousing 1 for providing a 3-dimentional movement. This is defined as the horizontalsliding ball seat 14 for providing the automatic positioning function. - With regard to the upper end of the
housing 1, a non-conductive verticalvibration adjusting knob 31, a non-conductive horizontalvibration adjusting knob 21 and a fixingtube locking knob 11 are disposed thereon. At the bottom of thehousing 1, based on a simple electrical connection, the loop(s) can be connected among these two detecting systems and battery, an alarm set, etc (this kind of simple electrical loop is just a prior art). When an earthquake occurs, thebattery 6 will send a signal to the alarm set 4 to send out certain voice(s) (like a speaker or beeper). Thisalarm set 4 includes ahorizontal alarm 41 and avertical alarm 42. Thus, it can detect different types of the earthquake. If it is out of electricity, by mean of thecharger 5, thelight 7 will be activated automatically for emergency escape. At the normal time for stand by, thecharger 5 can be charged continuously. After thecharger 5 is full, it will automatically stop or still keep in a constant charging condition. - When the earthquake contains the vertical vibration, the vertical vibration detecting system can detect it. The vertical vibration detecting system includes a first detecting set and a second detecting set. The first detecting set is composed of a non-conductive vertical
vibration adjusting element 31, awire 32 with a non-conductive outer wrap, aspring holding seat 36, adetective spring 37, adetective element 38, and aweight 310. The second detective set is composed of a non-conductive horizontalvibration adjusting element 21, a hangingspring 33, a detectingtube top cover 34, a half-insulatedsteel tube 35 having a non-conductive inner wall, and a vertical vibration,detective seat 39. - This vertical
vibration detective seat 39 is conductive. When the earthquake contains a vertical vibration, due to theweight 310, thedetective spring 37 is repeatedly moving up and down so as to cause a vertically vibration. Thisdetective spring 37 is disposed inside and limited by the half-insulatedsteel tube 35 and performs a vertical movement, so that thedetective element 38 of the first detecting set will contact with the verticalvibration detecting seat 39 of the second detective set. So, this contact will form an electrical loop to activate a vertical alarm 42 (as shown in FIG. 7). - By mean of an outer thread of the vertical
vibration adjusting element 31, the first detecting set is engaged into a non-conductive inner thread of the horizontalvibration adjusting element 21 of the second detecting set. And, an outer thread of the horizontalvibration adjusting element 21 is engaged into an inner thread of an upper end of a horizontal slidingball 13 so as to secure the first and second detecting sets. - When the earthquake contains the vertical vibration, the vertical vibration detecting system can detect it. The horizontal swinging (or vibration) detecting system includes another detecting set. It is composed of a fixed tube
upper cover 22, a fixedtube 2 and a horizontal detecting seat 23 (all conductive). Of course, this horizontalvibration detective seat 23 is conductive. When the earthquake wave contains a horizontal vibration, due to theweight 310, the hangingspring 33 is repeatedly horizontally swung so as to cause a horizontally vibration. Thus, theweight 310 will contact with the horizontalvibration detecting seat 23 so as to form an electrical loop to activate a horizontal alarm 41 (as shown in FIG. 5). - In which, an outer thread of the fixing tube
upper cover 22 is engaged in an inner thread of a lower end of the horizontal slidingball 13. So, the slidingball 13 can be disposed on a horizontal slidingball seat 14 in thehousing 1 with free sliding. - With regard to horizontal vibration detecting precision adjustment, the horizontal
vibration adjusting element 21 is adjustable to change a horizontal ring-like gap between theweight 310 and the horizontalvibration detecting seat 23 so that the sensitivity of horizontal vibration detecting can be adjusted (as shown in FIG. 6). When the horizontalvibration adjusting element 21 is rotated down, the horizontal gap between theweight 310 and the horizontalvibration detecting seat 23 becomes smaller so that the detecting sensitivity increases (as shown in FIG. 6A). If it is rotated up, the detecting sensitivity decreases (as shown in FIG. 6B). - With regard to vertical vibration detecting precision adjustment, the vertical
vibration adjusting element 31 is adjustable to change a vertical gap between the detectingelement 38 and the verticalvibration detecting seat 39 so that the detecting sensitivity of vertical vibration detecting can be adjusted (as shown in FIG. 8). When the verticalvibration adjusting element 31 is rotated up, the vertical gap between the detectingelement 38 and the verticalvibration detecting seat 39 becomes larger so that the detecting sensitivity decreases (as shown in FIG. 8A). If it is rotated down, the detecting sensitivity increases (as shown in FIG. 8B). - In addition, the horizontal sliding
ball 13 on the horizontal slidingball seat 14 of thehousing 1 can automatically make the fixingtube 2 and the detectingtube 3 towards down to the center of the earth so as to achieve the functions of automatically positioning and automatically returning. - Also, the fixing
tube locking knob 11 is used to secure the fixingtube 2 at a desired position after installing this invention. - For the detailed electrical circuit, it is shown in FIG. 9. The negative pole (means the ground) of the
battery 6 is connected to aground wire 73 and then connected to thewire 32 with a non-conductive outer wrap, thespring holding seat 36, thedetective spring 37, thedetective element 38, and theweight 310. So, this connection forms a ground route. The positive pole of thebattery 6 is connected with two routes. The first route is to connect with the first horizontal detectingwire 74 and then to connect with thehorizontal alarm 41, a second horizontal detectingwire 71, the fixing tubeupper cover 22, the fixingtube 2 and the horizontalvibration detecting seat 23. Therefore, once the horizontalvibration detecting seat 23 contacts with theweight 310, it forms a close loop so that it will activate thehorizontal alarm 41 to output a warning voice. Whereas, the second route from the positive pole is to connected with a first vertical detectingwire 75, and the to connect with avertical alarm 42, a second vertical detectingwire 72, the hangingspring 33, the detectingtube top cover 34, the half-insulatedsteel tube 35 having a non-conductive inner wall (such as inserting a plastic film), and the verticalvibration detective seat 39. Once the verticalvibration detective seat 39 contacts with the detectingelement 38, it forms another close loop so that it will activate thevertical alarm 42 to output another warning voice. - According to the test results obtained from the aftershocks of the severe earthquake happened in Taiwan on Sep. 21, 1999, and other smaller earthquakes happened in Chia-Yi area in Taiwan, these earthquake can be classified into the vertical vibration type, the horizontal vibration type and the mixed type (having both). However, this invention can precisely detect these three kinds of earthquakes. And, its advantages and functions can be summarized as follows:
- (1) East to assemble. This invention can be put on any flat or tilted place. The user does not need to worry about the ground is tilted or not. There is no need to assemble. It can be moved to any position. Also, it can be a decoration in a house or office.
- (2) Easy to adjust. Because there are the horizontal sliding ball and the hanging spring, it is easy to adjust this invention to a desired horizontal or vertical condition automatically.
- (3) Easy to return to the original state. No matter the vertical or the horizontal vibration, after detecting the earthquake, it will return to the original state without manual operation.
- (4) The alarm voices are different by types. This invention can distinguish the earthquake's vibration is the vertical type, the horizontal type or the mixed type, so the alarm voices are one of the two different voices or the mixed voice. Therefore, people will know what type it is and then make a best decision for emergency escape.
- (5) Depending on the amplitude of the external interfering vibration, the sensitivities of the vertical and horizontal vibration detecting can be adjusted.
- Thus, based on the above description, this invention is very easy to be used by people. There is no complex assembling or installing procedures. Also, except the initial locking procedure for the tilted ground, there is no other adjustment. After detecting the earthquake, this invention will return to its original state automatically. Therefore, it significantly improves the convenience in use. In addition, the detecting precision can be kept and can provide an immediately warning at the crucial moment.
- The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
