The invention discloses a sandy substrate sediment multi-tube sampler with an anti-buoyancy function, which comprises a comprehensive pillar, the bottom of the comprehensive pillar is fixedly connected with a combined cylinder, the bottom of the combined cylinder is fixedly provided with a comprehensive disc, the bottom of the comprehensive disc is fixedly provided with a main sampler, and the bottom of the main sampler is fixedly provided with an anti-buoyancy device. Four groups of uniformly arranged adjusting mechanisms are fixedly mounted at the bottom of the comprehensive disc, auxiliary samplers are fixedly connected to the outer surfaces of the four groups of adjusting mechanisms, and sealing discs are in threaded connection to the middles of the inner walls of the main sampler and the auxiliary samplers; the inner walls of openings in the bottom ends of the main sampler and the auxiliary sampler are in threaded connection with combined circular rings, and the tops of the combined circular rings are fixedly connected with a plurality of groups of triangular elastic sheets which are annularly arranged. According to the sampling device, opening and closing of the bottom sealing structure defined by the triangular elastic pieces can be controlled through stretching and retracting of the waterproof electric push rod according to whether sampling is conducted or not, so that sampling is facilitated, and the sampler pipe body is sealed after sampling is completed.
