Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5This utility model provides a technical solution: a groundwater pollution monitoring device, including a multi-parameter water quality testing instrument 1. The structure and principle of the multi-parameter water quality testing instrument 1 are conventional technologies and will not be described in detail in this application. A box 2 is assembled on the outside of the multi-parameter water quality testing instrument 1. The box 2 has symmetrically distributed partitions 21 and baffles 22 fixedly connected inside. The multi-parameter water quality testing instrument 1 and the box 2 are fixed together with screws to form a whole. The multi-parameter water quality testing instrument 1 and the box 2 are carried together and used outdoors. The box 2 can protect the multi-parameter water quality testing instrument 1. The partitions 21 and baffles 22 divide the internal space of the box 2 to facilitate the placement of test tubes and reagents used for testing. A lifting assembly includes a pull rod 32 that slides through the side of the box 2, a handle 31 fixedly connected to one end of the pull rod 32 that extends out of the outside of the box 2, and a handle 32 that extends through the side of the box 2. One end of the pull rod 32 is fixedly connected to the pressure column 33 inside the housing 2. When carrying the housing 2 and the multi-parameter water quality testing instrument 1, the handle 31 can be held by hand to carry the housing 2. When the handle 31 is pulled, the pull rod 32 slides in the direction b, the pressure column 33 moves and presses against the rotating plate 73. The rotating plate 73 rotates about the fixed column 71 as an axis, and the angle of the rotating plate 73 can be adjusted. The limiting component includes the fixed column 71 fixedly connected to the housing 2, the rotating plate 73 rotatably connected to the fixed column 71, the spring torsion spring 72 sleeved on the outside of the fixed column 71 and connected to the housing 2 and the rotating plate 73 at both ends respectively, and the locking block 74 fixedly connected to one end of the rotating plate 73. When the handle 31 is pulled, the pressure column 33 abuts against the rotating plate 73, and the rotating plate 73 rotates about the fixed column 71 as an axis, so that the locking block 74 is embedded in the interior of the housing 2.The test box cover 4 is slidably connected to the box body 2. An insert plate 41, which is pulled out of the box body 2, is fixedly connected to the inner surface of the test box cover 4. One end of the insert plate 41 has a groove 411 that engages with the locking block 74. When the test box cover 4 slides and forms a sealed box structure with the box body 2, the insert plate 41 on the test box cover 4 is inserted into the box body 2. When the handle 31 is pulled, the pressure column 33 abuts against the rotating plate 73, causing it to rotate and the locking block 74 to engage with the corresponding groove 411, thus limiting the insert plate 41 and ensuring that the box body 2 and the test box cover 4 form a complete box shell. A cover plate 42 is rotatably connected to the test box cover 4. The cover plate 42 can be flipped open to a vertical position. A placement plate is rotatably connected inside the cover plate 42. 62. The placement plate 62 can be flipped open to the vertical cover 42. In this application, the test chamber cover 4 and the chamber body 2 are a flat-opening shell structure. The flat-open test chamber cover 4 can serve as a horizontal platform for placing test tubes and reagents. In addition, test tubes and reagents can also be placed on the surface of the open placement plate 62 for easy access. An elastic band 44 connects the cover 42 and the test chamber cover 4. When mixing samples and reagents in a sealed test tube, the test tube is passed through the elastic band 44. Rotating the test tube causes it to twist the elastic band 44, which is in a taut and deformed state, generating elastic force. Releasing the test tube causes it to rotate rapidly under the elastic force of the elastic band 44, achieving the effect of mixing the solutions in the test tube.

[0028] In this embodiment, the multi-parameter water quality testing instrument 1 is installed inside the housing 2 and located between adjacent partitions 21. A first placement slot A is formed between the partitions 21 and the housing 2, and a second placement slot B is formed between the baffle 22, the partitions 21, and the housing 2. The test tubes and reagents used for testing can be swung inside the first placement slot A and the second placement slot B, which have a storage function.

[0029] In this embodiment, the handle 31 is a rectangular three-dimensional frame structure that can be carried by hand and is portable. The pressure column 33 includes a fixed part connected to the pull rod 32 and a push rod part in an inclined state. One end of the push rod part has a curved shape of a hemispherical surface. When the handle 31 is carried, the box 2 moves down under the action of gravity, the pull rod 32 pulls the pressure column 33 to move, and the push rod part pushes the rotating plate 73 to rotate, so that the locking block 74 is embedded in the interior of the insert plate 41, thereby achieving the effect of firmly inserting the insert plate 41 and detecting the box cover 4.

[0030] In this embodiment, the locking block 74 is an isosceles triangular three-dimensional structure. The locking block 74 and the insert plate 41 are in surface contact, with a large contact area, which increases the stability of the locking.

[0031] In this embodiment, the side of the box 2 is provided with a sliding groove 23 that cooperates with the insert plate 41, and the inner side wall of the box 2 is provided with a connecting groove 24 that communicates with the sliding groove 23. The locking block 74 corresponds to the connecting groove 24. The insert plate 41 slides in the corresponding sliding groove 23. The locking block 74 passes through the connecting groove 24 and is embedded in the interior of the insert plate 41, which can fix the insert plate 41.

[0032] In this embodiment, a first rotating cylinder 52 and a first fixed shaft 51 that rotates through the center of one side of the cover plate 42 are fixedly connected. There is frictional resistance between the first rotating cylinder 52 and the first fixed shaft 51. Under the action of frictional resistance, the first rotating cylinder 52 remains stable. The two ends of the first fixed shaft 51 are fixedly connected to the detection box cover 4. A second fixed shaft 61 with both ends fixedly connected to the cover plate 42 is rotatably connected to one side of the placement plate 62. There is frictional resistance between the placement plate 62 and the second fixed shaft 61. Under the action of frictional resistance, the opened placement plate 62 can remain stable without exceeding the weight limit.

[0033] In this embodiment, a square groove 43 is provided at the center of the cover plate 42 to cooperate with the cover plate 42. The cover plate 42 is closed in the square groove 43. A round hole is provided at the center of the elastic band 44, through which the test tube can pass for easy placement. A fixing cylinder 423 is fixedly connected to one side surface of the cover plate 42. A "T"-shaped knob 421 is rotatably connected to the fixing cylinder 423. A cuboid-shaped limiting plate 422 is connected to one end of the knob 421 by a screw. When the cover plate 42 is closed and flush with the surface of the test box cover 4 on the same side, rotating the knob 421 rotates the limiting plate 422, which then matches the inner surface of the test box cover 4, thus limiting the cover plate 42. There is frictional resistance between the knob 421 and the fixing cylinder 423, which keeps the knob 421 in a stable state.

[0034] Working principle and usage process of this utility model:

[0035] When testing groundwater pollution, open the closed box 2 and test box cover 4 and place them on a level surface. Press the handle 31, the pull rod 32 slides and drives the pressure column 33. With the spring spring 72 in motion, the rotating plate 73 rotates, causing the locking block 74 to leave the insert plate 41. The test box cover 4 can be opened outwards, so that it is in the open state with the box 2. Rotate the knob 421 to open the cover plate 42 and the placement plate 62 in sequence. The test tubes and reagents stored inside the box 2 can be placed on the test box cover 4 and the placement plate 62. Then operate the multi-parameter water quality testing instrument 1 to test the sample. It has a horizontal platform design that can hold test tubes and reagents.

[0036] After the test is completed, close the placement plate 62 and the cover plate 42 in sequence, rotate the knob 421, and the limiting plate 422 matches the inner surface of the test box cover 4, limiting the cover plate 42. Then slide the flat-open test box cover 4 along the a direction and form a box shell structure with the test box cover 4. When the handle 31 is lifted, the box body 2 moves down under the action of gravity, the pull rod 32 pulls the pressure column 33 to move, and the push rod pushes the rotating plate 73 to rotate, so that the locking block 74 is embedded in the interior of the insert plate 41, achieving the effect of firmly inserting the insert plate 41 and the test box cover 4.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
