Description

Technical Field

[0001] This utility model belongs to the field of wastewater quality monitoring technology, and in particular relates to an unattended wastewater quality monitoring and sampling device. Background Technology

[0002] Wastewater quality monitoring is a crucial step in environmental protection and wastewater treatment. By analyzing and detecting various components in wastewater, the nature of the wastewater, the degree of pollution, and the treatment effect are assessed. Sampling points are determined based on the type of wastewater discharge source and the monitoring objective. For wastewater treatment plants, sampling points include the inlet, the inlets and outlets of each treatment unit, and the outlet, in order to comprehensively evaluate the wastewater treatment effect. For wastewater discharge outlets of industrial enterprises, it is necessary to ensure that the sampling points can represent the actual wastewater discharge situation of the enterprise.

[0003] Unattended wastewater quality monitoring requires sampling at different time intervals to understand the water quality situation in a timely manner. Samples collected at different time intervals need to be processed centrally. Therefore, we designed an unattended wastewater quality monitoring sampling device that can automatically sample and collect discharged wastewater at different time intervals, making it easy to operate. Utility Model Content

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a winding machine to unwind the sampling cup, causing it to sink into the sewage due to its own weight. Then, the winding machine winds the cup up, and the sampling operation is completed by lifting the sampling cup. The moving section can drive the sampling cup to move and align with any sample collection cup. Then, the side-lifting component operates to lift the sampling cup upward, and the sewage sampled in the sampling cup is poured into the sample collection cup for collection. Sewage samples from different time periods are poured into different sample collection cups for collection. After multiple sample collection cups are collected, the operator can take out the sewage from the sample collection cups for testing. This achieves the purpose of automatically sampling and collecting discharged sewage according to time periods, which is convenient for operation.

[0012] 2. By setting a steel ring, the sample collection cup is placed in the inner cavity of the steel ring, which can limit the position of the sample collection cup, ensuring the firmness of the sample collection cup, and at the same time, the sample collection cup can be removed from the steel ring.

[0020] In the following description, embodiments of the unattended wastewater quality monitoring and sampling device of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates an unattended wastewater quality monitoring and sampling device according to an embodiment of the present invention. It includes a support 1, with a crossbar 2 fixedly connected to the inner cavity of the support 1. Steel rings 3 are fixedly connected at equal intervals to one side of the crossbar 2. A sample collection cup 4 is placed inside the steel rings 3. The steel rings 3 limit the placement of the sample collection cup 4 within their cavity, ensuring its stability while allowing it to be removed from the steel rings 3. An L-shaped plate 5 is slidably connected to the surface of the support 1. A winding machine 6 is mounted on the top of the L-shaped plate 5, and a steel wire rope 7 is mounted on the winding reel of the winding machine 6. The bottom of the steel wire rope 7 extends through the inner side of the L-shaped plate 5 and is fitted with a steel frame 8. A movable sampling cup 9 is mounted on the surface of the steel frame 8. A moving section 10 is provided between the L-shaped plate 5 and the support 1. The moving section 10 includes a threaded rod 101 rotatably connected to the inner cavity of the support 1. The surface of the threaded rod 101 is threaded... A threaded sleeve 102 is connected to the L-shaped plate 5. The top of the threaded sleeve 102 is fixedly connected to the L-shaped plate 5. A motor 103 is installed on one side of the bracket 1. The output shaft of the motor 103 is fixedly installed to the threaded rod 101. A side-lifting assembly 11 is provided between the sampling cup 9 and the L-shaped plate 5. The side-lifting assembly 11 includes a base plate 111 fixedly connected to both sides of the bottom of the L-shaped plate 5. A shaft pin 112 is fixedly connected to the opposite side of the two base plates 111. A swing rod 113 is rotatably connected to the surface of the shaft pin 112. A lifting plate 114 adapted to the sampling cup 9 is fixedly connected to the bottom of the two swing rods 113. A connecting rod 115 is fixedly connected to the top between the two swing rods 113. A cylinder 116 is fixedly installed on the top of the L-shaped plate 5. The output end of the cylinder 116 is rotatably connected to the connecting rod 115. A pouring port 117 for the liquid to be poured out of the sampling cup 9 is opened on one side of the L-shaped plate 5. Two movable grooves 118 for the base plate 111 to move are opened on the top of the L-shaped plate 5.

[0022] Working principle: In use, the sampling cup 9 sinks into the sewage due to its own weight by unwinding the winding machine 6. Then, the winding machine 6 winds up the wire rope 7, and the sampling cup 9 is lifted out to complete the sampling operation. The motor 103 drives the threaded rod 101 to rotate. The threaded sleeve 102 moves left and right due to the thread, which in turn moves the L-shaped plate 5, the winding machine 6, the wire rope 7, the steel frame 8, the sampling cup 9, and the side-lifting assembly 11, so that the sampling cup 9 can be aligned with any sample collection cup 4. Then, the cylinder 116 extends, driving the swing arm through the connecting rod 115. Rotating counterclockwise around the pivot pin 112 causes the lever 113 to rotate counterclockwise, which in turn causes the lifting plate 114 to rotate counterclockwise. This causes the bottom of the sampling cup 9 to be lifted upwards around the connection point between the steel frame 8 and the sampling cup 9. The top of the sampling cup 9 passes through the pouring port 117 and pours the wastewater sampled in the sampling cup 9 into the sample collection cup 4 for collection. Wastewater samples from different time periods are poured into different sample collection cups 4 for collection. After multiple sample collection cups 4 have been collected, the operator can collect the wastewater from the sample collection cups 4 for testing, so as to understand the wastewater data of each time period in a timely manner.

[0023] In summary, this unattended wastewater quality monitoring and sampling device uses a winding machine 6 to unwind the sampling cup 9, causing it to sink into the wastewater due to its own weight. The winding machine then rewinds the cup, lifting it out to complete the sampling operation. The moving section 10 drives the sampling cup 9 to align with any sample collection cup 4. The side-lifting component 11 then lifts the sampling cup 9 upwards, pouring the wastewater sampled from it into the sample collection cup 4 for collection. Wastewater samples from different time periods are poured into different sample collection cups 4. Once multiple sample collection cups 4 have been collected, the operator can collect the wastewater from each cup for testing. This achieves the goal of automatically sampling and collecting discharged wastewater according to time periods, facilitating operation.
