Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, specifically to an automatic sewage sampling device. Background Technology

[0002] Wastewater generally refers to polluted wastewater from domestic and industrial processes. It mainly includes domestic sewage, industrial wastewater, and initial rainwater runoff. Major pollutants in wastewater include pathogens, oxygen-consuming pollutants, plant nutrients, and toxic pollutants. Wastewater sampling refers to the process of extracting water samples from polluted water according to prescribed methods and proportions. By testing and analyzing the extracted water samples, the degree of water pollution, the types and concentrations of pollutants, and other relevant water quality parameters are determined. This information guides production activities and enables the implementation of relevant measures to reduce water pollution.

[0003] Based on the above, the inventors have discovered the following problems: In the current sewage sampling process, sewage sampling devices can generally only complete one sampling operation. For flowing sewage, the composition and concentration of sewage passing through the same location may change over time, and relying on only one sampling will lead to insufficient accuracy and reliability of the test results.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic sewage sampling device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide an automatic wastewater sampling device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An automatic wastewater sampling device includes a sampling mechanism, a placement mechanism, and a base assembly. The placement mechanism includes a placement cylinder with a limiting block connected inside. The limiting block has four equidistant limiting grooves inside. Sliding strips are connected to the inner walls of the placement cylinder at the four limiting grooves. Sampling collection cylinders are slidably mounted on the outside of the four sliding strips. The outer walls of the four sampling collection cylinders are respectively clearance-fitted with the inner walls of the four limiting grooves. Liquid level sensors are provided on the inner walls of the four sampling collection cylinders away from the sliding strips. The sampling mechanism includes a first fixed seat and a second fixed seat, with a top cover located near the upper end between the first fixed seat and the second fixed seat.

[0008] Furthermore, the base assembly includes a circular seat, and a steering wheel is connected to the interior of the upper surface of the circular seat via a bearing. The upper surface of the steering wheel is connected to the bottom end of the placement cylinder.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since the steering wheel is connected to the upper end face of the circular seat through a bearing, and the upper end of the steering wheel is connected to the bottom end of the placement cylinder, the rotation of the placement cylinder is facilitated when the steering wheel rotates at the circular seat.

[0010] Furthermore, a motor is provided at the bottom of the circular seat, and the output end of the motor is connected to the steering wheel. A controller is connected to the front of the circular seat, and the motor, several liquid level sensors and the controller are electrically connected by wires.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting up a motor, it is easy to drive the steering wheel to rotate when the motor is working. Through the cooperation of the motor, liquid level sensor and controller, the liquid level sensor will transmit the liquid level data monitored in the sampling collection cylinder to the controller, and then the controller controls the motor to work.

[0012] Furthermore, the first and second fixed seats are connected to the outer walls of the circular seats on opposite sides near the bottom. The upper end of the first fixed seat is hinged with a hinge block, and the upper end of the second fixed seat is provided with a connecting block. The opposite sides of the connecting block and the hinge block are connected to the outer walls of the top cover. A threaded hole is provided at the center of the connecting block. Bolt holes are provided on both outer sides of the second fixed seat near the upper end. Fastening bolts are threadedly connected between the two bolt holes and the threaded holes.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the hinge block and the connecting block, since the hinge block is hinged inside the upper end of the first fixed seat and the connecting block is set inside the upper end of the second fixed seat, it is easy to open the top cover. By opening bolt holes on both sides of the outside of the second fixed seat, and threaded connecting bolts between the two bolt holes and the threaded hole, when the fastening bolts are rotated and unscrewed, the connecting block and the second fixed seat are no longer fixedly connected.

[0014] Furthermore, the bottom end of the top cover is in contact with the upper end face of the placement cylinder, and a circular hole is provided on one side of the upper end face of the top cover. A liquid outlet pipe is connected inside the circular hole, and the bottom end of the liquid outlet pipe is flush with the upper end face of the limiting block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting a top cover, since the inside of the round hole on the top cover is connected to the liquid outlet pipe, and the liquid outlet pipe is located at the upper end of one of the sampling collection cylinders, it is convenient to transport sewage to the inside of the sampling collection cylinder. Since the bottom end of the liquid outlet pipe is flush with the limiting block and fits with the bottom end of the top cover and the upper end of the placement cylinder, the top cover, the first fixing seat, the second fixing seat and the base assembly form a whole. When the placement cylinder rotates between the top cover and the round seat, the bottom end of the liquid outlet pipe first fits with the top of the limiting block under the rotation of the placement cylinder and then is located at the upper end of the sampling collection cylinder again.

[0016] Furthermore, a J-shaped hook is connected to the outer wall of the top cover, and a second flexible hose is wound around the J-shaped hook. One end of the second flexible hose is connected to a water intake head. A micro pump is provided at the center of the upper end of the top cover. The water outlet of the micro pump is connected to a first flexible hose. The end of the first flexible hose away from the micro pump is connected to one end of the liquid outlet pipe. The water inlet of the micro pump is connected to the end of the second flexible hose away from the water intake head through a flange.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting a J-shaped hook, since a second flexible hose is wound around the J-shaped hook, it is easy to wind the longer second flexible hose around the J-shaped hook for easy storage. When the water head is put into the sewage, it is convenient to sample the sewage. By setting a micro pump, when the micro pump is working, the sewage enters the interior of the sampling collection cylinder through the water head, the second flexible hose, the first flexible hose and the liquid outlet pipe, thereby completing the automatic sampling work.

[0018] Furthermore, the outer wall of the water inlet head is provided with several water inlet holes, and a counterweight is connected to the outside of the water inlet head near the second hose. Both the counterweight and the water inlet head are made of stainless steel.

[0019] The beneficial effects of adopting the above-mentioned further solution are that by opening several water inlet holes on the outer wall of the water intake head, water can be easily introduced while large particulate impurities are filtered out, preventing foreign objects from entering the micro pump and causing damage to the micro pump. By setting a counterweight, the overall weight of the water intake head is increased. By making the counterweight and the water intake head out of stainless steel, the service life of the counterweight and the water intake head is improved.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic sewage sampling device, by installing a limiting block inside the placement cylinder and opening four limiting grooves within the limiting block, facilitates the placement of the sampling collection cylinder within the limiting grooves. Simultaneously, the sampling collection cylinder is slidably connected to a sliding strip, thereby improving the stability of the sampling placement cylinder within the limiting grooves. Liquid level sensors are installed on the inner walls of the four sampling collection cylinders to monitor the sewage level height within them. A top cover is provided, and an outlet pipe is connected to the internal circular hole of the top cover, with the outlet pipe located in one of the holes. The upper end of the sampling collection cylinder facilitates the delivery of sewage into the cylinder. Since the bottom end of the outlet pipe is flush with the limiting block and fits against the bottom end of the top cover and the upper end of the placement cylinder, the top cover, the first fixing seat, the second fixing seat and the base assembly form a whole. When the placement cylinder rotates between the top cover and the circular seat, the bottom end of the outlet pipe first fits against the top of the limiting block under the rotation of the placement cylinder and then repositions itself at the upper end of the sampling collection cylinder, thus facilitating secondary sampling. Since there are four sampling collection cylinders, it is convenient to sample the same sewage area multiple times. Attached Figure Description
