Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a wastewater testing water sample storage device. Background Technology

[0002] Wastewater generally refers to polluted wastewater from domestic and industrial processes. It mainly includes domestic sewage, industrial wastewater, and initial rainwater runoff. The main pollutants in wastewater include pathogens, oxygen-consuming pollutants, plant nutrients, and toxic pollutants. With the continuous increase in my country's population and the rapid expansion of the number and size of cities, various wastewater problems are becoming increasingly serious, necessitating frequent water quality testing to determine the content of pollutants.

[0003] In water quality testing, the water samples are typically collected in bottles and taken back to the research institute for testing. During the journey back, the bottles containing the water samples need to be stored and protected. However, most water quality testing sample storage devices are currently simple box-type storage containers that lack a structure to secure the bottles. During transportation, the bottles are prone to collisions and breakage, failing to provide effective protection. In addition, during field sampling, due to environmental limitations, the storage containers are often placed directly on the ground. When using the storage containers, staff need to constantly bend over and squat, which increases unnecessary labor intensity and reduces work efficiency. Utility Model Content

[0004] This utility model provides a wastewater testing water sample storage device with a reasonable structural design, which can fix and clamp sample bottles and is convenient for staff to operate, in order to solve the technical problems existing in the prior art.

[0005] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A wastewater testing water sample storage device includes an upper shell and a lower shell that can be interlocked. One side of the upper shell and the lower shell are hinged together by a hinge, and the other side is locked together by a snap lock. Multiple sets of clamping devices for holding sample bottles are connected in the inner cavity of the lower shell. Two sets of symmetrically arranged first leg structures that can be supported and retracted are hinged to one end of the bottom surface of the lower shell by a hinge seat, and two sets of symmetrically arranged second leg structures that can be supported and retracted are hinged to the other opposite end by a hinge seat. Through holes for inserting locking pins are provided on both sets of hinge seats. Rollers are connected to both sets of first leg structures, and a horizontally arranged pull rod is connected between the two sets of second leg structures.

[0006] The clamping device includes a fixed clamping block and a movable clamping block arranged opposite to each other. The opposing surfaces of the movable clamping block and the fixed clamping block are both arc-shaped. The fixed clamping block is detachably connected to the lower housing. A spring-loaded clamping structure is connected to the movable clamping block to press the sample bottle clamped between the fixed clamping block and the movable clamping block against the arc-shaped surface of the fixed clamping block.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a wastewater testing water sample storage device. The upper and lower shells can be used to store sample bottles, and multiple clamping devices can hold and fix the sample bottles, preventing breakage due to collisions and providing effective protection. The first and second support legs allow the upper and lower shells to be raised to a suitable position during operation, avoiding the need for staff to constantly bend over and squat, conforming to ergonomics, reducing labor intensity, and improving work efficiency. Furthermore, after the sampling and storage process is completed, the first and second support legs can be folded up, reducing space occupation and facilitating transportation. The rollers and pull rods improve the device's mobility, making it easy for staff to move the device to a suitable location.

[0018] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail:

[0019] Please see Figure 1 The wastewater testing water sample storage device of this utility model includes an upper shell 9 and a lower shell 7 that can be interlocked. One side of the upper shell 9 and the lower shell 7 are hinged together by a hinge, and the other side is locked together by a latch lock 3. The movable end of the latch lock 3 is connected to the side wall of the lower shell 7, and the fixed end is connected to the side wall of the upper shell 9. A handle 4 is connected to the lower shell 7.

[0020] Multiple sets of clamping devices 8 for holding sample vials are connected to the inner cavity of the lower housing 7, and the multiple sets of clamping devices 8 are arranged alternately. See further details. Figure 3 In this embodiment, the clamping device 8 includes a fixed clamping block 8-7 and a movable clamping block 8-6 arranged opposite to each other. The opposing surfaces of both the movable clamping block 8-6 and the fixed clamping block 8-7 are arc-shaped. The fixed clamping block 8-7 is detachably connected to the lower housing 7. To prevent damage to the sample vial from the movable clamping block 8-6 and the fixed clamping block 8-7, both are made of rubber. Furthermore, to increase the friction between the vial and the clamping blocks, transversely arranged protruding ridges are provided on the arc-shaped surfaces of both the movable clamping block 8-6 and the fixed clamping block 8-7. A spring-loaded clamping structure is connected to the movable clamping block 8-6 to press the sample vial clamped between the fixed clamping block 8-7 and the movable clamping block 8-6 against the arc-shaped surface of the fixed clamping block 8-7.

[0021] In this embodiment, the spring tightening structure includes a positioning block 8-2 detachably connected to the lower housing 7. Multiple sets of laterally arranged guide columns 8-4 are slidably connected to the positioning block 8-2 via linear bearings. A limit plate 8-1 is connected to one end of the guide column 8-4, and a clamping block mounting seat 8-5 is connected to the other end. A movable clamping block 8-6 is connected to the clamping block mounting seat 8-5. A tightening spring 8-3 is provided between the positioning block 8-2 and the clamping block mounting seat 8-5, and the two ends of the tightening spring 8-3 are respectively tightened against the positioning block 8-2 and the clamping block mounting seat 8-5.

[0022] The operating principle of clamping device 8 is as follows: During use, the operator needs to move the movable clamping block 8-6 away from the fixed clamping block 8-7. At this time, the tensioning spring 8-3 is compressed under the action of external force. When the movable clamping block 8-6 is moved to the appropriate position, the sample bottle is placed between the movable clamping block 8-6 and the fixed clamping block 8-7. Then, the movable clamping block 8-6 is released. Under the elastic force of the tensioning spring 8-3, the movable clamping block 8-6 will press the sample bottle against the arc-shaped surface of the fixed clamping block 8-7, thereby clamping and fixing the sample bottle. Clamping device 8 can prevent the bottle from breaking due to collision, providing effective protection.

[0023] like Figure 1 As shown, two sets of symmetrically arranged first leg structures 1, which can be supported and retracted, are hinged to one end of the bottom surface of the lower housing 7 via hinge seats. Two sets of symmetrically arranged second leg structures 5, which can also be supported and retracted, are hinged to the opposite end of the lower housing 7 via hinge seats. Through holes for inserting locking pins are provided on both sets of hinge seats. Rollers 2 are connected to both sets of first leg structures 1, and a horizontally arranged pull rod 6 connects between the two sets of second leg structures 5. The rollers 2 improve the mobility of the storage device, preventing it from being difficult to move when the storage device is too heavy. In this embodiment, the first leg structure 1 and the second leg structure 5 have identical structures. To facilitate the retraction of the leg structures and avoid mutual interference when they are retracted, the first leg structure 1 and the second leg structure 5 on the same side are centrally symmetrically arranged.

[0024] See further Figure 2The first support leg structure 1 includes a hollow first short support leg 1-3. One end of the first short support leg 1-3 is hinged to the lower housing 7 via a hinge seat and a pin, and the other end is hinged to a first long support leg 1-1 via a pin. A first locking member 1-2 is slidably connected to the inner cavity of the first short support leg 1-3. A strip-shaped hole extending along its length is provided on the first locking member 1-2, and the hinge shaft for hinged first long support leg 1-1 and first short support leg 1-3 passes through the strip-shaped hole of the first locking member 1-2. Through holes for inserting locking pins are provided on the first long support leg 1-1, the first short support leg 1-3 and the first locking member 1-2.

[0025] like Figure 4 As shown, when the support leg structure is in the retracted state, the locking element retracts into the short support leg, and the long support leg and short support leg flip and fit together, touching the bottom surface of the lower housing 7. At this time, a locking pin can be inserted into the corresponding through hole as needed to lock the hinge seat to the short support leg and the long support leg to the short support leg, preventing the support leg structure from flipping and affecting the working process. After completing the sampling and storage process, the first support leg structure 1 and the second support leg structure 5 can be retracted, reducing the space occupied and facilitating transportation.

[0026] like Figure 2 As shown, when the support leg structure needs to be opened to support the lower housing 7, simply pull out the corresponding locking pin, flip the long and short support legs so that they are parallel, with the interior angle between the short support leg and the lower housing 7 being an obtuse angle. After opening the long and short support legs, the locking piece needs to be pulled out, and then the corresponding locking pin is inserted to lock the hinge seat to the short support leg and the locking piece to the long support leg, preventing the support leg structure from flipping and affecting the working process. When the support leg structure is in the supported state, it can raise the longitudinal position of the lower housing 7, avoiding the need for workers to constantly bend over and squat when using the storage device, which is ergonomic, reduces labor intensity, and improves work efficiency.

[0027] Working Principle: During field sampling, the first leg structure 1 and the second leg structure 5 are opened, supporting the upper shell 9 and the lower shell 7. The opening process of the leg structure is as described above and will not be repeated here. After opening the upper shell 9 and the lower shell 7 and completing the water sample bottling, the water sample bottle is held in place by the clamping device 8. This is done by moving the movable clamping block 8-6 to increase the distance between the movable clamping block 8-6 and the fixed clamping block 8-7, placing the water sample bottle between the arc-shaped surfaces of the movable clamping block 8-6 and the fixed clamping block 8-7. The movable clamping block 8-6 is then released, and under the elastic force of the tensioning spring 8-3, the movable clamping block 8-6 presses the sample bottle against the arc-shaped surface of the fixed clamping block 8-7, thus clamping and fixing the sample bottle. After clamping all the sample bottles, the upper shell 9 and the lower shell 7 are fastened together and locked using the snap lock 3. Finally, the leg structure is retracted and locked using the locking pin. At this point, staff can pull lever 6 and use rollers 2 to move the entire storage device onto a transport vehicle or other suitable location.
