Space seismograph and seismograph arrangement system

The utility model discloses a space seismograph and a seismograph arrangement system, and relates to the technical field of seismograph design. The space seismograph comprises a seismograph body, a protection piece, an unhooking piece, a sensing module and a connecting part. A first containing cavity is formed in the seismograph body, and the protection piece covers the inner wall of the top of the seismograph body so as to form a second containing cavity with the inner wall of the top of the seismograph body. The shielding member is arranged on the external surface of the seismograph body, so that direct interference of noise sources such as solar storm and barometric storm can be shielded. After the control part of the unhooking piece receives the releasing signal, the fixing part and the connecting part are disconnected, and therefore the sensing module moves from the second containing cavity to the first containing cavity. In the first accommodating cavity, the sensing module is not rigidly connected with
