Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sample collection, in particular to a sample collection device for chemical sewage sampling. Background Art

[0002] Chemical wastewater refers to wastewater produced in the process of producing products in chemical plants, such as oily wastewater from the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank area, air separation and air compression station, etc., which is discharged after biochemical treatment to meet the emission standards. When treating wastewater, it is necessary to sample the wastewater to facilitate better sewage treatment. At present, sewage sampling is to store the sewage in test tubes and take it back to the laboratory for further inspection. The test tubes are generally placed in a test tube box for carrying. However, in actual use, the space in the test tube box is not divided, and each test tube needs to be marked to avoid confusion, which is not conducive to the efficient sampling work. At the same time, in order to facilitate the placement of test tubes, the distance between two adjacent test tubes inside the test tube box is large, resulting in low utilization of the internal space of the test tube box. Therefore, improvements are needed to address the above problems. Utility Model Content

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] The sample storage device has the functions of partitioning and test tube lifting and adjusting. The partition design can separate the test tubes of different samples to avoid confusion, effectively ensuring the efficiency of sampling work, and the test tube lifting and adjusting can effectively reduce the storage distance between adjacent test tubes, thereby improving the utilization rate of the storage space.

[0017] Depend on Figures 1 to 4 The utility model includes a truncated cone shell 1, and seven storage chambers 2 are equidistantly provided on the top arc of the truncated cone shell 1. Through the setting of the seven storage chambers 2, effective partitioning can be achieved, and the storage chamber 2 has a square structure, and a fixing plate 3 is fixedly installed on the upper part of the storage chamber 2. A double row of sockets 4 for placing test tubes are equidistantly provided on the surface of the fixing plate 3. The setting of the sockets 4 can stably place the test tubes, and a movable plate 5 that can be raised and lowered and adjusted is installed at the lower part of the storage chamber 2.

[0018] The circumferential surface of the truncated cone shell 1 is rotatably connected with seven rotatable and adjustable inverted L-shaped sealing plates 6 at equal intervals in an arc shape. The upper part of the inverted L-shaped sealing plate 6 blocks the upper part of the storage chamber 2 for sealing. A limit stopper 7 is fixedly installed in the middle part of the upper end of the inverted L-shaped sealing plate 6. A circular rotating tube 8 is rotatably connected to the middle part of the top of the truncated cone shell 1. The limit stoppers 7 are all located below the circular rotating tube 8. An arc-shaped through groove 9 is provided on the circumferential surface of the circular rotating tube 8. The limit stoppers 7 can be effectively moved out from below the circular rotating tube 8 through the arc-shaped through groove 9 to allow the inverted L-shaped sealing plate 6 to be rotatably adjusted.

[0019] The lower part of the storage chamber 2 is rotatably connected with a bidirectional threaded shaft 10, and both sides of the bidirectional threaded shaft 10 are threadedly connected with a moving block 11, and two connecting rods 12 are rotatably connected between the top of the two moving blocks 11 and the bottom of the movable plate 5, so that the movable plate 5 can be effectively adjusted, and one end of the bidirectional threaded shaft 10 extends to the surface of the frustum shell 1 and is fixedly connected with a first bevel gear 13, and the circumferential surface of the frustum shell 1 is rotatably connected with seven rotating pins 14 at equal intervals, and the middle part of the rotating pin 14 is fixedly connected with a second bevel gear 15 meshing with the first bevel gear 13, and the inner side of the lower part of the inverted L-shaped sealing plate 6 is fixedly connected with the rotating pin 14, so that the inverted L-shaped sealing plate 6 can be effectively adjusted and effectively transmitted;

[0020] When the inverted L-shaped sealing plate 6 needs to be rotated and opened, the circular rotating tube 8 is rotated to align the arc-shaped through groove 9 with the limit stopper 7 on the inverted L-shaped sealing plate 6 that needs to be opened, and then the inverted L-shaped sealing plate 6 is rotated to make the limit stopper 7 move out of the arc-shaped through groove 9, and the rotation of the inverted L-shaped sealing plate 6 will drive the rotating pin 14 to rotate, and the rotation of the rotating pin 14 will drive the first bevel gear 13 to rotate, and the rotation of the first bevel gear 13 will drive the two-way threaded shaft 10 to rotate, and the rotation of the two-way threaded shaft 10 will cause the two moving blocks 11 to move relative to each other, and the two moving blocks 11 moving in opposite directions will push the movable plate 5 to move upward through the connecting rod 12, and the upward movement of the movable plate 5 will push the test tube to move upward, so that the test tube is moved out from the inside of the insertion hole 4 and the inside of the storage chamber 2 for easy removal;

[0021] When the inverted L-shaped sealing plate 6 is rotated to open, the test tube carrying the sealing cover and the sampled sewage can be inserted into the interior of the socket 4 and the test tube can be located on the top of the movable plate 5. When the inverted L-shaped sealing plate 6 is rotated to close, the inverted L-shaped sealing plate 6 can effectively contact the top of the test tube (i.e., the test tube sealing cover), so that the test tube can be stably and effectively stored inside the storage chamber 2.

[0022] An operating block 16 is fixedly installed on the top of the surface of the inverted L-shaped sealing plate 6 for rotatable adjustment of the inverted L-shaped sealing plate 6. Arc grooves 17 aligned with the socket 4 are equidistantly provided on the top of the movable plate 5. The setting of the arc grooves 17 facilitates the stable and safe placement of the test tube. A cutting surface 18 is provided on the circumferential surface of the frustum shell 1, and a holding handle 19 is fixedly installed in the middle of the cutting surface 18, so that the storage device can be conveniently carried and held.

[0023] A circular groove 20 is provided at the top of the truncated cone housing 1, and eight V-shaped grooves 21 are provided at equal intervals in a circular shape at the bottom of the circular groove 20. The V-shaped grooves 21 are aligned with the limit stopper 7. Two mounting grooves 22 are symmetrically provided at the bottom of the circular rotating tube 8. T-shaped pins 23 are movably inserted inside the two mounting grooves 22. A spring 24 is fixedly connected between the top of the T-shaped pin 23 and the top of the mounting groove 22. A roller 25 is installed at the bottom of the T-shaped pin 23. The roller 25 is located inside the V-shaped groove 21, so that the rotation of the circular rotating tube 8 can be stably and effectively adjusted.

[0024] When the roller 25 is located inside the V-shaped groove 21, the circular rotating tube 8 can remain stable due to the limitation of the V-shaped groove 21 and will not rotate automatically and easily. When the circular rotating tube 8 needs to be rotated, the circular rotating tube 8 drives the T-shaped pin 23 to move by rotating the circular rotating tube 8. The movement of the T-shaped pin 23 drives the roller 25 to move from the inside of the V-shaped groove 21 to the inside of the ring groove 20 and causes the T-shaped pin 23 to compress the spring 24. The entire adjustment operation is stable and reliable.

[0025] At the same time, the sample storage device has a simple structural design, is convenient and easy to use and operate, and has stable and reliable storage and adjustment. Its performance can meet the use requirements of chemical wastewater sampling.
