the upper part of the sample bin 1 is hinged with a sample bin cover 2; a sampling box 3 is arranged at the upper part of the sample bin cover 2;

the wall of the sampling box 3 is embedded with a sampling box operation screen 5 (the sampling box operation screen 5 adopts a full touch screen and has the function of an operation panel, compared with a key-type operation panel which is generally adopted by a traditional sampler and is separated from a display screen, the operation is more convenient, the user interface is more friendly, the stability and the durability are higher), and a peristaltic pump 6 (a high-performance peristaltic pump and a hybrid stepping motor are adopted for subdivision driving, the operation is stable and reliable, an easily-assembled pump head is adopted, the liquid is not polluted when being contacted with a pipeline, and the high temperature and corrosion resistance are realized), a motor 11 and a rotary joint 12 are arranged inside the box body of the sampling box 3, the device comprises a driver 13 and a power supply 15 (220V external alternating current can be adopted for power supply (an adapter is needed), and a built-in storage battery can be adopted for power supply, so that the built-in storage battery can provide power under the condition that the external power supply is accidentally disconnected, and sampling pause is avoided); the lower end of the rotary joint 12 is movably fixed in the middle of the box body of the sampling box 3 through a bearing, and a rotating shaft of the motor 11 is provided with a worm; a worm wheel is arranged on the rotary joint 12, and the worm wheel is meshed with the worm; the motor 11, the driver 13, the power supply 15 and the sampling box operation screen 5 are connected through a line; a water inlet 7 is formed in the wall of the sampling box 3, and the water inlet 7 is sequentially connected with a peristaltic pump 6 and a rotary joint 12 through pipelines; the lower end of the rotary joint 12 is connected with a distribution conduit 17, the distribution conduit 17 penetrates out of the sample bin cover 2, the distribution conduit 17 is in a transverse Z-shaped tubular shape, and the distribution conduit 17 can be suspended right above a sample bottle groove of the sample box 16 under the driving of the rotary joint 12.

The bottom of the sample bin 1 is provided with universal wheels.

Sample box 16 is the box body that the cross-section is regular octagon, and evenly is equipped with eight appearance bottle grooves on the box body, and eight 450 mL's sampling bottle can be placed in the appearance bottle groove. The sampling requirement (generally sampling for 1-7 days) of most sewage toxicity monitoring works can be met, and under the premise, the machine body is reduced as much as possible (the length is less than 50 cm, and the width and the height are less than 40 cm), so that the transportation is convenient.

The wall of the sampling box 3 is provided with a pressure relief opening 8; and a branch pipe is arranged on a pipeline between the peristaltic pump 6 and the rotary joint 12 and is connected with the pressure relief port 8.

The distribution conduit 17 is provided with a reset contact 18 on the conduit wall; a reset needle 19 for contacting the reset contact 18 to reset the distribution conduit 17 is arranged on the sample bin cover 1 and right above the first sample bottle groove of the sample box 16.

And a wireless router 10 is arranged in the box body of the sampling box 3, and information such as the running state and the position of the equipment is synchronized to an online monitoring platform in real time.

The box wall of the sample cabin 1 is provided with a telescopic rod 4, and the upper end of the telescopic rod 4 can be provided with a camera or a sunshade umbrella. Information such as the running state, the sampling amount and video images of the surrounding environment of the instrument can be transmitted to the platform client in real time through the communication network and the camera of the instrument, real-time online monitoring is achieved, and smooth sampling is guaranteed.

And a pipeline from the peristaltic pump 6 to the rotary joint 12 is provided with a branch pipe connected with a pressure relief port 8. When the internal pipeline is blocked, water flows out through the pressure relief opening 8, and the internal pipeline is prevented from bursting or leaking due to pressure rise.

And a water flow sensor is arranged on a pipeline from the water inlet 7 to the rotary joint 12. A high-sensitivity water flow sensor is arranged in the sampling system, so that the sampling amount is accurate.

And the sample bin cover 2 is provided with an intelligent lock for locking the sample bin cover 2 and the sample bin 1. The intelligent lock design prevents the sampling program from being illegally tampered and the sample bin 1 from being illegally opened in the sampling process, and reduces the risk of human intervention. The sampling bottle has specially designed the bottle lid of preventing opening, guarantees going on smoothly of sample authenticity and sampling work.

Through sampling box operation panel 5, peristaltic pump 6, motor 11, driver 13 isotructure, can realize around sampling at every turn, deposit water in the automatic evacuation pipeline, guarantee that the pipeline does not produce the deposit and blocks up, effectively reduce sample cross contamination's risk.

By setting the rinsing times, the pipeline can be rinsed for the set times before sampling, and the risk of cross contamination of samples is reduced.

In fig. 5, a pipeline connected with the water inlet 7 firstly enters the sampling box 3, bypasses the rear end of the peristaltic pump 6, and then returns to the inside of the sampling box 3 after passing through the peristaltic pump 6 from the outside of the sampling box 3 until being connected with the rotary joint 12. The advantage of doing so is that peristaltic pump 6 is bulky, settle on 4 tank walls of sampling box, borrow the space of 4 outsides of sampling box, the volume of sampling box 4 has been practiced thrift, and because 4 inner spaces of sampling box are limited, the pipeline easily takes place local flattening deformation in 4 contents of sampling box, lead to the sample to flow through smoothly, the design of sampling pipeline detouring inside and outside sampling box 4, can reduce the pipeline in the inside shared space of 4 of sampling boxes, avoid the pipeline local situation of taking place flattening deformation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
