Technical Field

[0001] The utility model relates to the technical field of water quality detection equipment, in particular to a multi-chamber sewage sampler. Background Art

[0002] The sewage sampler is a device used to collect various types of water samples. It uses a highly reliable peristaltic pump to extract water samples and quantitatively collects the sewage at the sampling point into the sampling bottle inside the equipment. Nowadays, in order to facilitate water quality testing personnel to conduct multiple sampling at the same sewage sampling point, multiple sewage storage bottles of equal volume are arranged inside the sewage sampler. The sewage sampler stores the sewage quantitatively in the sewage storage bottles.

[0003] For example, an integrated sewage sampler disclosed in authorization announcement No. CN215492670U includes a base plate and a device box, wherein the device box is fixedly installed on the top of the base plate, and a liquid storage tank is fixedly installed on the top of the inner cavity of the device box through a bracket. There are three liquid storage tanks from top to bottom, and the liquid storage tanks are fixedly connected by connecting blocks. The right side of the liquid storage tank is connected to a water inlet pipe, and a first solenoid valve is fixedly installed on the surface of the water inlet pipe.

[0004] In the prior art, when sampling sewage, it is necessary to use a water intake pipe to perform multiple sampling at the sewage sampling point. After sampling, it is necessary to go to different sewage sampling points for re-sampling. When the water intake pipe is sampling at the previous sewage sampling point, the sewage from the previous sewage sampling point will remain inside the water intake pipe, causing the sewage from the previous sewage sampling point remaining in the water intake pipe to mix into the next sewage sampling point, thereby affecting the sampling accuracy of the existing sewage sampler. Utility Model Content

[0010] Preferably, a weight slot is provided on the outer side of one end of the water suction pipe, and a weight block is movably connected inside the weight slot.

[0011] Preferably, a No. 2 electric valve is fixedly installed on the outer side of the sewage collection pipe.

[0012] Preferably, a No. 3 electrically-controlled valve is fixedly installed on the outer side of the No. 3 water pipe.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the inside of the water suction pipe and the sewage temporary storage box are cleaned by the cooperation between the clean water tank and the No. 1 water pump. After using the multi-chamber sewage sampler, the water suction pipe is first placed inside the clean water tank, and the No. 1 water pump is started. The No. 1 water pump draws the cleaning liquid inside the clean water tank into the inside of the water suction pipe and into the sewage temporary storage box, and finally enters the inside of the clean sewage tank through the No. 1 water pipe, so that the sewage remaining in the water suction pipe and the sewage temporary storage box is flushed into the inside of the clean sewage tank, avoiding the situation where the sewage from the previous sewage sampling point remaining in the water intake pipe is mixed into the inside of the next sewage sampling point, thereby improving the accuracy of sewage sampling by the multi-chamber sewage sampler.

[0015] 2. In the utility model, the water inlet pipe is collected through the cooperation between the pipe collection box and the turntable. When the sampling is completed, the user grasps the handle to rotate the turntable to drive the suction pipe and the water inlet pipe to rise from the water. The user does not need to grasp the water inlet pipe immersed in sewage to collect the water inlet pipe, thereby improving the user's comfort when using the multi-chamber sewage sampler.
