Description

Technical Field

[0001] This utility model relates to the field of environmental testing equipment technology, specifically to a water quality sampling device. Background Technology

[0002] Textile printing and dyeing is an important process in the textile industry. A large amount of water is used in the textile printing and dyeing process. After going through dyeing, printing, washing and other stages, the water used in the printing and dyeing process often becomes wastewater. This wastewater is then discharged after a series of purification treatments.

[0003] Currently, regular water quality sampling and testing are generally required for important rivers and waterways near textile dyeing and printing enterprises to monitor whether the wastewater discharged by these enterprises meets discharge standards. Common sampling methods involve staff manually sampling at water sources using specialized sampling equipment such as water sample bottles and samplers. Existing automatic sampling devices (such as buoy-type, cable-type, or remote-controlled water quality sampling equipment) are constantly exposed to the aquatic environment and are susceptible to water flow impact, aquatic organism attachment, and siltation, leading to sampling port blockage, sensor malfunction, or structural corrosion, thus reducing sampling frequency and data accuracy.

[0026] See Figures 1-6 .

[0027] To address the problems mentioned in the background section, this utility model provides a water quality sampling device to solve the aforementioned technical problems. The technical solution is as follows:

[0028] A water quality sampling device includes: a column 110, a lever arm 120, a horizontal moving mechanism, a first motor 141, an active drum, a lifting rope 142, a counterweight 143, a sampling hose 161, a horizontal limiting rod 151, a lifting ring 152, and a pump body; wherein, the structure of the pump body is not shown in the figures.

[0029] The lever arm 120 is horizontally connected to the column 110; the horizontal moving mechanism slides on the lever arm 120; the horizontal moving mechanism can move along the length of the lever arm 120.

[0030] A horizontal limiting rod 151 is fixed to one side of the lever arm 120 and arranged along the length of the lever arm 120; multiple lifting rings 152 are spaced apart on the horizontal limiting rod 151;

[0031] The first motor 141 is fixed on the horizontal moving mechanism, the active drum is fixed on the main shaft of the first motor 141, the first end of the lifting rope 142 is fixedly wound on the active drum, and the counterweight 143 is fixed on the second end of the lifting rope 142.

[0032] The first end of the sampling hose 161 passes through multiple lifting rings 152 in sequence and is finally fixed to the counterweight 143; the lifting rings 152 are provided to prevent the sampling hose 161 from swinging freely.

[0033] The end of the sampling hose 161 extends downward through the counterweight 143 and to the lower part of the counterweight 143; the second end of the sampling hose 161 is connected in series with the pump body.

[0034] The counterweight 143 is fixed to the end of the sampling hose 161 by the suspension rope 142. It serves to stabilize the sampling hose 161 and ensure that the sampling hose 161 is upright and vertically extended in the water. At the same time, the counterweight 143 can also help the end port of the first end of the sampling hose 161 to be lowered to a suitable depth. The end port of the first end of the sampling hose 161 is also the sampling port.

[0035] In this embodiment, the horizontal moving mechanism includes a fixed frame 131, a first side plate 132, a second side plate 133, a driven roller 134, a driving roller 135, and a second motor 136;

[0036] The lever arm 120 is an H-beam, and the lever arm 120 includes a web 121 and an upper flange and a lower flange 122 fixed on both sides of the web 121.

[0037] The first side plate 132 and the second side plate 133 are fixed at intervals on the top of the fixing frame 131; the driven roller 134 is rotatably connected to the inner side of the second side plate 133, and the driving roller 135 is rotatably connected to the inner side of the first side plate 132; the driven roller 134 and the driving roller 135 overlap and limit the lower wing plate 122 on both sides.

[0038] The second motor 136 is fixed on the first side plate 132, and the main shaft of the second motor 136 is fixedly connected to the drive roller 135; the first motor 141 is fixed to the bottom of the fixing frame 131.

[0039] The second motor 136 drives the active roller 135 to rotate, which in turn drives the horizontal moving mechanism to move along the length of the lever arm 120.

[0040] In this embodiment, a guide wheel 170 is provided on the column 110, and the second end of the sampling hose 161 passes around the guide wheel 170 before being connected to the pump body; the function of the guide wheel 170 is to help the sampling hose 161 run smoothly in the device and avoid tangling or obstruction during movement.

[0041] In this embodiment, the lever arm 120 is horizontally rotatably connected to the column 110; the lever arm 120 is not fixed, but can rotate horizontally, so that the angle of the sampling device can be adjusted, allowing it to operate in different directions.

[0042] The method of using the water quality sampling device provided in this embodiment of the utility model is as follows:

[0043] A base was built on the bank of the important monitored water area using cement and steel reinforcement. The column 110 of the water quality sampling device was fixed to the base with bolts to complete the assembly of the water quality sampling device.

[0044] 2. During sampling, the first motor 141 drives the drum to rotate, winding and unwinding the hoisting rope 142, thereby adjusting the sampling depth of the sampling hose 161; the counterweight 143 keeps the sampling hose 161 stable as it sinks to the predetermined water depth.

[0045] 3. When the opening at the first end of the sampling hose 161 reaches the predetermined water depth, the pump body starts to work and draws water samples; at the same time, a sampling container is placed at the opening at the second end of the sampling hose 161 to collect water quality data.

[0046] 4. Once sampling is complete, the first motor 141 starts again, the drum retracts the hoisting rope 142, and drives the sampling hose 161 and the counterweight 143 back to the starting position, completing one sampling cycle.

[0047] It should be noted that when it is necessary to clean the opening of the first end of the sampling hose 161, the horizontal moving mechanism is controlled to move towards the shore along the length of the lever arm 120. After moving to the appropriate position, the staff manually cleans the opening.

[0048] The water quality sampling device provided in this embodiment of the present invention has the following beneficial effects: The present invention designs a water quality sampling device that can realize the automated operation of water quality sampling and can control the water depth position of the sampling, and is easy to operate.
