The invention relates to a
water sample collector and solves a problem of inconvenient opening of a sampling
bottle. The
water sample collector provided with a response acceleration mechanism includes a sampling
bottle, an inhaul cable, a weight and the response acceleration mechanism, the response acceleration mechanism comprises a
vertical cylinder, an upper driving rod and a lower driving rod, the top wall of the sampling
bottle is provided with an upper one-way valve, the bottom wall of the sampling bottle is provided with a lower one-way valve, the upper one-way valve and the lower one-way valve respectively comprises a channel and a valve core arranged in the channel, the weight is arranged at the bottom of the sampling bottle, the cylinder comprises a cylinder body and a
piston connected to the inside of cylinder body in a sliding seal manner, a sealed gas cavity is formed between the cylinder body and the
piston, the cylinder body is fixedly connected with the sampling bottle, the lower end of the lower driving rod traverses through the gas cavity and then is connected with the
piston, the upper end of the lower driving rod is connected with the valve core of the lower one-way valve, the upper end of the upper driving rod is connected with the valve core of the upper one-way valve, and the lower end of the upper driving rod is connected with the valve core of the lower one-way valve. The
water sample collector has the advantages of automatic opening and closing of the sampling bottle, and short
response time of the opening and closing.
