Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sampling and testing device for wastewater treatment engineering. Background Technology
[0002] In the wastewater treatment process, in order to detect whether the wastewater treatment meets the standards or to detect the content of certain substances, it is necessary to use sampling and testing devices to extract wastewater from the wastewater tank and transfer it to the laboratory for specific testing.
[0003] Existing sampling and testing devices can only extract water at a certain depth, limiting the sampling depth range. Furthermore, after each extraction, the sample needs to be transferred to another storage tube before being immersed in water for further sampling, making the sampling process cumbersome and complicated. Utility Model Content
[0004] The purpose of this invention is to address the following shortcomings in the existing technology: the depth of water that can be extracted by existing sampling and testing devices is limited, the sampling depth range is limited, and after each extraction, it is necessary to transfer the sample to another storage tube before it is put back into the water for sampling, which makes the sampling process cumbersome and complicated. Therefore, this invention proposes a sampling and testing device for wastewater treatment engineering.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sampling and testing device for wastewater treatment engineering includes a float plate, an L-shaped plate fixedly installed on the back of the float plate, a drive motor symmetrically fixedly installed on the surface of the L-shaped plate, two pull ropes fixedly wound on the output shaft of the drive motor, two pairs of openings on the surface of the float plate, and the ends of the multiple pull ropes away from the output shaft of the drive motor passing through the multiple openings and fixedly installed on the mounting plate.
[0007] Multiple mounting rods are fixedly installed at equal intervals on the upper surface of the mounting plate. A sampling groove is opened at one end of each mounting rod, and a piston rod is slidably and sealed inside the sampling groove. One end of each mounting rod is fixedly connected to an inlet pipe and an outlet pipe. Both the inlet pipe and the outlet pipe are equipped with one-way valves. Multiple sliding openings corresponding to the positions of the piston rods are opened at equal intervals on the upper surface of the float plate. Vertical plates are slidably arranged in the sliding openings. A sliding groove is opened at the bottom end of the vertical plate, and a sliding plate is slidably inserted in the sliding groove. Multiple electric telescopic rods are fixedly installed at equal intervals on the upper surface of the float plate. The drive shafts of the multiple electric telescopic rods are fixedly connected to the multiple vertical plates respectively. A controller electrically connected to the multiple electric telescopic rods is provided on the upper surface of the float plate.
[0008] Preferably, a plurality of telescopic rods are fixedly installed on the lower surface of the float, and the bottom end of the telescopic rods is fixedly connected to the upper surface of the mounting plate.
[0009] Preferably, the upper surface of the float is provided with multiple sets of guide components, and the multiple sets of guide components are used to support multiple ropes respectively.
[0010] Preferably, the guiding component includes a pair of support plates fixedly installed on the upper surface of the float and an I-shaped guide wheel. The guide wheel is horizontally rotatable between the two support plates, and each of the pull ropes is respectively laid inside each guide wheel.
[0011] Preferably, the one-way valve in the inlet pipe is directed from the outside to the sampling tank, and the one-way valve in the outlet pipe is directed from the sampling tank to the outside.
[0012] Preferably, the opening wall is coated with a smooth paint, and the smooth paint is polytetrafluoroethylene.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By coordinating the drive motor and the pull rope, the installation plate can be quickly moved to a suitable water depth for sampling. The water depth for sampling is no longer fixed. Furthermore, through the coordination of multiple piston rods and multiple electric telescopic rods, water samples at different depths can be taken sequentially after the installation plate enters the water. This avoids the cumbersome step of transferring previously taken samples before each sampling. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A sampling and testing device for wastewater treatment engineering includes a float plate 1, an L-shaped plate 2 fixedly installed on the back of the float plate 1, a drive motor 3 symmetrically fixedly installed on the surface of the L-shaped plate 2, two pull ropes 4 fixedly wound on the output shaft of the drive motor 3, two pairs of openings opened on the surface of the float plate 1, the ends of the multiple pull ropes 4 away from the output shaft of the drive motor 3 passing through the multiple openings respectively and fixedly installed on the mounting plate 5, and multiple telescopic rods 15 fixedly installed on the lower surface of the float plate 1, the bottom end of the telescopic rods 15 being fixedly connected to the upper surface of the mounting plate 5;
[0023] Multiple mounting rods 6 are fixedly installed at equal intervals on the upper surface of the mounting plate 5. A sampling groove is opened at one end of the mounting rod 6. A piston rod 7 is slidably and sealed inside the sampling groove. One end of the mounting rod 6 is fixedly connected to the inlet pipe 8 and the outlet pipe 9. Both the inlet pipe 8 and the outlet pipe 9 are equipped with one-way valves. The one-way valve in the inlet pipe 8 is directed from the outside to the sampling groove, and the one-way valve in the outlet pipe 9 is directed from the sampling groove to the outside. Multiple sliding ports 10 are opened at equal intervals on the upper surface of the float plate 1, which correspond to the positions of the multiple piston rods 7. A vertical plate 11 is slidably arranged in the sliding port 10. A sliding groove is opened at the bottom of the vertical plate 11, and a sliding plate 12 is slidably inserted in the sliding groove. Multiple electric telescopic rods 13 are fixedly installed at equal intervals on the upper surface of the float plate 1. The drive shafts of the multiple electric telescopic rods 13 are fixedly connected to the multiple vertical plates 11. A controller 14 is provided on the upper surface of the float plate 1 and is electrically connected to the multiple electric telescopic rods 13.
[0024] When sampling is required, firstly, the multiple electric telescopic rods 13 are extended to minimize the space between the ends of the multiple piston rods 7 and the wall of the sampling tank. Then, the float 1 is placed into the sewage tank, allowing it to float on the water surface. At this point, the two drive motors 3 are activated, causing their output shafts to rotate relative to each other. This controls the multiple pull ropes 4 to simultaneously retract or release. When the pull ropes 4 retract, the mounting plate 5 moves upward along with the multiple mounting rods 6, multiple piston rods 7, and multiple sliding plates 12. When the pull ropes 4 release, the mounting plate 5 moves downward along with the multiple mounting rods 6, multiple piston rods 7, and multiple sliding plates 12, thereby adjusting the sampling depth. The installation plate 5 will extend and retract as it moves, which can prevent the installation plate 5 in the water from moving laterally relative to the floating plate 1 on the pool. When the installation plate 5 moves to the appropriate sampling depth, the controller 14 can control one of the electric telescopic rods 15 to retract, which will move the vertical plate 11 fixedly connected to the drive shaft of the electric telescopic rod 15, the sliding plate 12 slidably inserted in the vertical plate 11, and the piston rod 7 fixedly connected to the sliding plate 12 away from the sampling tank. The volume of the space between the end of the piston rod 7 and the wall of the sampling tank will increase and the pressure will decrease. The water at the installation plate 5 will then enter the sampling tank from the inlet pipe 8, thereby completing the sampling of the water at that depth.
[0025] Then, by starting the drive motor 3, the mounting plate 5 is moved to a suitable depth. At this time, another electric telescopic rod 15 is started to control another piston rod 7 to move away from the sampling tank, thereby realizing the sampling of water at that depth. Water at different depths can be sampled into multiple mounting rods 6 in sequence, avoiding the cumbersome steps of transferring the previously sampled samples before each sampling.
[0026] Furthermore, the electric telescopic rod 15 can move precisely with the piston rod 7, so compared with manual sampling, the amount of water sampled will not be too much or too little, thus achieving the effect of precise sampling.
[0027] After sampling is completed, the mounting plate 5 is removed, and then multiple electric telescopic rods 13 are activated. The drive shafts of the multiple electric telescopic rods 13 move multiple piston rods 7 into multiple sampling slots. The volume of the space between the end of the piston rod 7 and the wall of the sampling slot will decrease, the pressure will increase, and the water in the sampling slot will be discharged from the outlet pipe 9.
[0028] The upper surface of the float 1 is provided with multiple sets of guide components, which are used to support multiple ropes 4. The guide components include a pair of support plates 16 fixedly installed on the upper surface of the float 1 and an I-shaped guide wheel 17. The guide wheel 17 is horizontally rotatably installed between the two support plates 16. Each rope 4 is laid in each guide wheel 17. The guide wheel 17 can support and guide the rope 4.
[0029] The opening wall is coated with a smooth paint, which is polytetrafluoroethylene (PTFE). The PTFE paint can reduce the friction between the opening wall and the surface of the pull rope 4.
[0030] In this invention, the installation plate 5 can be quickly moved to a suitable water depth by the cooperation between the drive motor 3 and the pull rope 4, so as to carry out sampling work. The water depth that can be sampled is no longer fixed. Furthermore, by the cooperation between multiple piston rods 7 and multiple electric telescopic rods 13, after the installation plate 5 enters the water, water samples at different depths can be taken in sequence, avoiding the cumbersome steps of transferring the previously sampled samples before each sampling.
[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
