The invention relates to an underwater side-scan sonar collecting and releasing device arranged under a boat bow deck. The device is characterized in that the boat bow is provided with a slot so as to be convenient for arranging the sonar on the boat bow, the slot can also be used for collecting an underwater sonar, and after the sonar is collected, the sonar can be covered; the sonar is arranged on a collecting and releasing rod, and the collecting and releasing rod is driven through a transmission device comprising an electromotor, a speed reducer, a stainless steel chain, and the like to rotate so as to send the sonar into water; after the sonar reaches a boat bow working position vertical to the bottom of the boat, an electrical push rod pushes a positioning pin to insert into a positioning hole so as to improve the rigidity of the sonar collecting and releasing rod; and the rotation angle of collecting and releasing the sonar is measured by an encoder connected to a rotation shaft. The imaging quality of the sonar arranging device is high, and the device can realize the quick collection and release of the underwater sonar; after the sonar is placed, the positioning pin is inserted, which can effectively guarantee the working precision of the sonar; the sonar can be guaranteed to be correctly collected and released through the encoder; and by integrating the three points, the detection precision of the sonar can be effectively and greatly improved, and the device is convenient to use.
