The utility model discloses a mechanical underwater depthkeeping disengaging device, including an outer sleeve, an inner sleeve, a seal sliding block and a spring, wherein the inner diameter of the outer sleeve is in clearance fit with the outer diameter of the inner sleeve, the seal sliding block and the spring are placed in the inner sleeve, a floater rod is screwed into a threaded hole in the top of the inner sleeve, and the lower end of the outer sleeve is fixed with an instrument rod for suspending a deep sea submerged buoy by a fastening bolt. The inner sleeve is provided with round holes which are uniformly spaced and equal in heights, and balls are placed into the round holes. Grooves are respectively arranged on the inner wall of the outer sleeve and the outer side of the lower part of the seal sliding block, the quantity of the grooves is identical with that of t=the round holes formed in the inner sleeve, and the plurality of grooves with identical heights are respectively arranged at intervals on the inner wall of the outer sleeve and the outer side of the lower part of the seal sliding block. According to the mechanical underwater depthkeeping disengaging device, the outer sleeve and inner sleeve which are respectively provided with the grooves and the round holes are combined with the seal sliding block which is provided with the groove and moves along with water depth pressure, so that the submerged buoy connected to the outer sleeve is connected or disconnected with the floater connected to the inner sleeve; the mechanical underwater depthkeeping disengaging device has the characteristics of simple structure, low cost, stable performance and convenience for use.
