Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling equipment, in particular to a water quality sample storage box for environmental testing. Background Art

[0002] In water quality analysis, most pollutants are sampled on site and then sent back to the laboratory for analysis and determination. In order to truly reflect the quality of the water body, in addition to using sophisticated instruments and accurate analysis techniques, special attention should be paid to the collection and preservation of water samples. This requires that the sample storage box should have sufficient capacity to accommodate multiple sampling tubes to meet the sampling quantity requirements; it should also provide effective shock and collision protection to prevent the tubes from being damaged during collection and transportation. However, the storage boxes currently on the market are usually composed of a box body and a perforated plate. Although the structure is simple and the cost is low, during the process of taking and placing the test tubes, the box body is completely open and prone to bumps. Especially when the box body accidentally overturns, there is a risk that all the test tubes will fall out and break. A new type of storage box is needed to solve the above problems.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] like Figures 1 to 4 As shown, a water quality sample storage box for environmental testing includes a cylinder 1, and a threaded ring 102 is provided on the upper section of the outer cylinder wall of the cylinder 1. The threaded ring 102 can be threadedly connected with the side edge of the cylinder cover 10 and the inner ring surface of the convex ring 103 at the bottom of the cylinder 1. A pillar 2 is provided at the center of the bottom of the cylinder 1, and a support plate 3 is provided in the middle of the column body of the pillar 2. A plurality of rows of cylinder holes 301 are evenly arranged on the surface of the support plate 3. A sampling assembly is placed in the cylinder hole 301. The sampling assembly includes a sampling tube 6, and the sampling tube 6 is equipped with a plug cover 7. The tube body of the sampling tube 6 is covered with a rubber spiral tube 8. The outer thread of the middle section of the rubber spiral tube 8 is threadedly connected with the inner thread of the upper section of the hole wall of the cylinder hole 301.

[0018] In this embodiment, a truncated cone 201 is provided at the center of the top of the pillar 2, and the side arc surface of the truncated cone 201 is rotatably connected to the center hole of the turntable 4. The screw hole on the top surface of the truncated cone 201 is threadedly connected to the limit bolt 9, and the bottom surface of the nut of the limit bolt 9 fits with the top surface of the turntable 4. An adjusting ring 403 is provided on the top surface of the turntable 4, and the side arc surface of the adjusting ring 403 is provided with anti-skid patterns. The anti-skid patterns can make it easier for the operator to rotate the turntable 4. The turntable 4 can close the opening of the cylinder 1, and the turntable 4 is radially opened. There is a take-in and put-out port 401 with a cover plate 5, and the take-in and put-out port 401 can rotate with the turntable 4 to match the position of one row of cylinder holes 301. A plurality of legs are arranged around the bottom surface of the cover plate 5, and each leg corresponds to the position of a through hole on the side ear plate 402 of the take-in and put-out port 401 and a positioning hole 101 provided on the top surface of the cylinder edge of the cylinder body 1. When the cover plate 5 is installed on the take-in and put-out port 401, the legs inserted into the positioning holes 101 can hinder the rotation of the turntable 4, and the sampling tube 6 cannot be taken in and put in at this time.

[0019] The working principle of the utility model is as follows:

[0020] The staff carries the storage box to the target water area, removes the cover plate 5, pinches the upper section of the rubber spiral tube 8 to screw the sampling tube 6 out of the barrel hole 301, and fixes the sampling tube 6 in the original position again after the sampling is completed. When the sampling components in the barrel holes 301 of this column are fully filled, the turntable 4 is rotated by adjusting the ring 403 to make the following barrel holes 301 carrying the empty sampling tubes 6 rotate to the bottom of the access port 401. When the sampling tubes 6 in the cylinder 1 are fully filled, the cylinder 1 can be stacked on other fully loaded cylinders 1 by the cooperation of the threaded ring 102 and the convex ring 103. When it is necessary to unload in the laboratory, the limit bolt 9 can be removed and the turntable 4 can be taken out for unloading. The utility model can realize the access port 401 and each column of barrel holes 301 by rotating the turntable 4, so as to realize the access and placement of the sampling components, avoid the influence of accidents such as improper operation on the other sampling components during the sampling process, and improve the safety factor of the storage box.
