Description of the invention (ί) (Please read the notes on the back before filling out this page) The present invention generally relates to a seismic detector, especially to a speed ground rattan detector. An earthquake detector is an instrument used to convert seismic energy into electrical voltage by responding to the speed of seismic waves. The most common seismic detector is a velocity seismic detector, in which a mass is suspended by a spring from a casing in a magnetic field generated by a permanent magnet installed in the casing. This quality includes metal wire (coils) wound on a bobbin. A shock wave can move the housing and the magnet, and the coil lags initially, and then moves back and forth from the original position in a swinging manner under the action of a spring. Because a charged particle that moves at right angles to a magnetic field in a material such as a coil is a magnetic flux density "B" (the number of magnetic field lines per unit area that moves or is at a right angle to the object) and velocity "V" acts at right angles, so the relative movement of the magnetic field relative to the coil of length "1" will generate a voltage in the coil as follows: V = v B 1 (1) Beigong, Central Bureau of Standards, Ministry of Economic Affairs The voltage printed by the consumer cooperation is proportional to the relative speed of the coil relative to the magnet caused by ground energy. It is assumed that the magnetic flux density is substantially constant. The voltage signal generated by the seismic detector can be used to predict the location of the underground formation reflecting the ground S energy. The voltage signal generated by the earth detector is mainly due to ground roll and harmonic distortion. -3- This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). The A7 B7 is printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of invention (2) True. The ground roll wave is a surface-wave energy that travels along or near the ground. The source and geophone pattern, frequency filtering and stacking are used to reduce the effect of the ground roll wave to a minimum. degree. It also refers to the energy array and geophone pattern of the space array that have been to be configured to prevent the ground roll wave from gathering. During the collection of 2D land and agricultural data, this technique is quite effective, but it is not effective in the collection of 3D seismic data. Other ground-rolling wave minimization techniques are post-data gathering processing techniques, which are also effective in 2D seismic data. However, the elimination of the harmonic distortion caused by the seismic detector when the ground roll wave will suppress the effectiveness of this post-data aggregation processing technique. Harmonic distortion is the nonlinear distortion produced by the harmonics of the input frequency. The spring used by the Xianxin earthquake detector is the main cause of harmonic distortion. Therefore, the spring of the ground sunflower detector has developed several different designs in an effort to reduce the generation of additional harmonics, including The springs shown in US Patent Nos. 3,74 2,441 and 4,623,991. Such a recently developed spring has a certain degree of effectiveness in reducing harmonic distortion, but it cannot completely solve the problem, and the phenomenon of residual distortion also greatly affects the analysis of the input signal. As mentioned before, this image is more significant in 3D seismic data than in 2D seismic data. Since more information about below ground level can be obtained during this data collection period, the industry standards for this paper are applicable to the Chinese National Standard (CNS> A4 specifications (210X 297mm) (please read the precautions on the back before filling in This page) 袈 · Order A7 __B7 5. Description of the invention (5) Since the world has collected the trend of collecting three-dimensional geothermal data, this problem has become increasingly important. According to the present invention, a coil that travels through a non-uniform magnetic field, It will also cause non-linearity (Ν ο η-1 inearity) of the ground sunflower detector circuit, and thus contribute to the distortion of harmonics. The speed of the commonly used speed detector is shaped as shown in Figure 1, one of which includes a magnet 104. The permanent magnet assembly covered with poles H14 and 20 is installed in a housing 102, which generates a magnetic field indicated by the magnetic field line 18 in the air gap 106 between the magnet assembly and the housing. The ring coil holder 10δ has Coils 22 and 23 are mounted on it, and this coil-shaped bobbin 108 is suspended by the springs 10 and 12 in the space between the magnet assembly and the housing 102, as described above when the housing is moved by seismic waves, each The coil can be in the magnetic field Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page). Each pole Η is made of magnetic material and is installed at the opposite end of the permanent magnet. Shaping can control the distribution of magnetic flux (Uagnetic flux) in the adjacent air gap. As shown in Figs. 1 and 2, the magnetic flux in the air gap is formed only in the space between each pole piece and the case, and the pole piece is transmitted more than the length of each coil 22 and 23 is shorter. However, because the size and strength of the magnet are not allowed, it is impossible to increase the width of each pole piece beyond the level shown in the figure while maintaining the overall size of the seismic detector as shown in Figure 1. If the size of the magnet is reduced and the size of the poles K is increased, the strength of the generated magnetic field is insufficient to properly operate the seismic detector. The magnetic field of the conventional magnet shown in Figure 1 is provided with a line between the magnet and the shell. -5- This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). Printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 314596 A7 ___B7_ 5. Description of the invention (4) The circles 22 and 23 are not uniform in the space. Figure 2 shows the relative magnetic flux density distribution of a conventional magnet measured across a magnetic pole from the middle of the magnet. This graph shows that for any displacement, the magnetic flux density is not uniform. It is now believed that the non-uniformity of this magnetic field will cause bad harmonics and distort the resulting signal. Therefore, the object of the present invention is to provide an earthquake detector with a relatively short and strong magnet, which can generate two uniform magnetic fields in the annular space between each pole H and the housing, and The width of the coils carried by the coil holder in the detector can substantially reduce the harmonic distortion in the output signal of the seismic detector. Another object and feature of the present invention is to provide an earth detector that is beneficial to the occurrence of less harmonic distortion in the seismic input signal, by virtue of the endogenous or even more uniformity in the annular space with the coil path between the magnet and the housing The magnetic field produces a high-resolution linear output signal. Various attempts to design a seismic detector that can produce a uniform magnetic field have long been frustrated by the need to maintain the industry standard requirement for the geophone reader to be about 1.25 inches (31.7 mm) long. Therefore, another object of the present invention is to provide a seismic detector having a uniform magnetic field and conforming to the overall industry standard length. In addition, another object of the present invention is to provide a geocai detector, which has a relatively strong magnetic field to increase the strength of the output signal.

The mesh element Η 2 of the spring is electrically connected to the opposite end of the spring 124 with the help of the snap ring device 125 and the silver layer of the coil holder 108 is electrically connected to the air through the spring 112 The pole K 120 is connected. The blade 120 is electrically connected to the terminal 132 via the permanent magnet 104 and the pole H 114. The conductive contact material 136 is placed between the terminal 132 and the pole K 114. The purpose is to increase electrical contact. The plate springs 140 and 142 are placed between the housing 102 and the upper and lower support devices, respectively, to prevent the coil bracket from colliding with the upper or lower support devices. Therefore, during careless operation or handling can be reduced The axial vibrations imparted to the coil holder will be discussed in detail later in this specification. In the preferred embodiment of the present invention, the total length of the seismic detector housing 102 is approximately 1.25 inches (31.7 mm) and meets industry standard specifications. The length of the magnet is about 0.20 (0.51mm), and the length of each piece of K is about 0.25 inch (0.64mm) if measured from the magnet to the upper and lower parts of each pole. -9-The size of this paper is applicable to the National Standardization (CNS) A4 specifications (2 [0Χ297mm) ··-*-Gas ^ ------ 1Τ ------ ^ (Please read first (Notes on the back and then fill in this page) Economical Langzhong folder Li Falcon " Employee two nights fee plus Zida paperback 314596 A7 _B7_ V. Description of invention (y) The permanent magnet material used can choose any magnetic material with sufficient magnetic field strength In order to accommodate each of the above-mentioned long inches and generate a magnetic field strength, it is enough for each coil to produce an output response (Output response), any magnet with a high coercive force (Coercive force) can be used to generate a uniform magnetic field, In a typical example, it should have a magnetization force of more than 4000 Oersted, and its residual induction (Residual induction) is greater than 6000 Gauss (Gauss) magnetic induction. It has been found that a magnet made of rare earth materials (Rare earth 'naterials) has excellent functions, such as Arn η ο 1 d E ngineering 〇f 11 1 i η 〇 is) Samarium cobalt arnax 22 (Samarium cobalt arnax 22) is the demagnetization curve related to the samarium cobalt amax 2 2 magnet at 25 degrees Celsius . The Yamax 22 magnet is quite brittle. Therefore, before the magnet is installed in the seismic detector, a layer of Nickel Plating of about 500 inches in thickness should be plated on the magnet to make it possible to eliminate the possibility of magnet fragmentation during manufacturing and on-site use Sexually occurs. The plating layer is also made by Annold Engineering Company. Increasing the pole H length relative to the length of the individual coils can provide a more uniform magnetic field, and the coils 122 and 123 move through this magnetic field. As a result, harmonic distortion in the output signal of the seismic detector can be reduced. Figure 4 shows the magnetic flux such as the magnetic field generated by the seismic detector shown in Figure 3.
