[0022] 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.
[0023] Example
[0024] like Figures 1-3 As shown, an embodiment of the present invention provides a loess undisturbed sample collection and preservation device, including a protective box 1 and a protective cover 2. The protective box 1 and the protective cover 2 are rotatably connected by a rotating shaft. A handle 3 is rotatably connected to the side wall of the protective box 1, and a latch 4 is rotatably connected to the protective cover 2. The latch 4 is rotatably locked to the side wall of the protective box 1.
[0025] The protective box 1 has a handle 3 rotatably connected to the side wall for easy handling; the protective cover 2 has a latch 4 rotatably connected to it, which is locked to the side wall of the protective box 1. During handling, the latch 4 locks the protective box 1 and the protective cover 2 to ensure the stability of the device and prevent the protective box 1 and the protective cover 2 from separating due to bumps during transportation, thus avoiding damage to the original loess sample.
[0026] The protective box 1 has sealing protrusions 5 around its perimeter, the protective cover 2 has sealing grooves 6 around its perimeter, and a sponge pad 7 is glued and fixed to the protective cover 2.
[0027] The sealing protrusion 5 and the sealing groove 6 are matched in shape and size and correspond in position. The two, together with the sponge pad 7, greatly enhance the overall sealing performance, effectively prevent the intrusion of external impurities and the loss of sample moisture, maintain a stable environment inside the chamber, and protect the properties of the loess original sample from external factors.
[0028] The protective box 1 is fitted with a loading box 8, which has four storage holes 9, and each storage hole 9 is covered with a sealing cover 10.
[0029] This design is convenient to classify and place multiple loess undisturbed samples, and the sealing cover 10 can realize the preliminary sealing and preservation of a single sample, avoid the mutual influence between samples, and better maintain the original state of the sample.
[0030] One side of the loading box 8 is provided with a groove 13, and a sealing door 14 is rotatably connected in the groove 13. One end of the sealing door 14 is fixedly connected with a U-shaped stop block 15, and a limiting rod 16 is rotatably connected in the groove 13.
[0031] When loading the ice bag, the sealing door 14 is rotated to seal the opening of the loading box 8, and then the limiting rod 16 is rotated to the middle of the stop block 15 to be lapped and locked, so that the space where the ice bag is located is closed. The ice bag is used for refrigeration to provide a suitable low-temperature preservation environment for the loess undisturbed sample, which helps to maintain the stability of the sample properties. In addition, the ice bag can be loaded or kept hollow as needed, which increases the flexibility of the device in use.
[0032] When the loess undisturbed sample preservation device is working, the loading box 8 is loaded into the protection box 1, and the ice bag is loaded into the hollow structure in the loading box 8. The sealing door 14 is rotated to seal the opening of the loading box 8, and the limiting rod 16 is rotated to the middle of the stop block 15 to be lapped and locked, so that the space where the ice bag is located is closed. The ice bag in this part can be loaded or kept hollow. Then the loess undisturbed sample is loaded through a disposable preservative bag, and then is placed in the preservation and placement hole 9 of the loading box 8. The handle 12 on the sealing cover 10 is rotated to close the sealing cover 10, so as to realize the preliminary sealing and preservation of a single sample. The protection cover 2 is closed, the sealing protrusions 5 around the protection box 1 are matched with the sealing grooves 6 on the protection cover 2, and the sponge pad 7 on the protection cover 2 is added, so as to further enhance the overall sealing performance, prevent foreign matters from entering and water from being lost. Then, the device can be carried by the handle 3, and the protection box 1 and the protection cover 2 are locked by the lock 4 to ensure the stability of the device during transportation, maintain the stable environment in the box, and protect the loess undisturbed sample.
[0033] As shown in Figure 1 In some embodiments, the sealing protrusions 5 and the sealing grooves 6 are matched in size and shape, and the positions are corresponding. This close cooperation can effectively block the air, dust, moisture and other impurities in the outside world from entering the inside of the device, prevent the loess undisturbed sample from being contaminated or changing properties due to environmental changes, greatly maintain the stability of the preservation environment in the box, and ensure the integrity and original characteristics of the loess undisturbed sample.
[0034] As shown in Figure 3 In some embodiments, the sealing cover 10 is provided with an inlay groove 11, and a U-shaped handle 12 is rotatably connected on the inner wall of the inlay groove 11. This design provides a force point for users to open and close the sealing cover 10.
[0035] As shown in Figure 2As shown in the drawings, in some embodiments, the loading box 8 is a hollow structure, and an ice bag is loaded inside; the design can be selected according to actual needs whether to load the ice bag. If the loess original sample does not need a low-temperature environment, or in some special cases, the ice bag cannot be obtained, the loading box 8 can be kept hollow, and the ice bag is not loaded, so that the use of the device is more flexible, and different preservation scenes and research needs can be adapted.
[0036] As shown in the drawings, Figure 2 As shown in the drawings, in some embodiments, the sealing door 14 seals the opening of the hollow loading box 8; the sealing door 14 separates the space loaded with the ice bag from the preservation hole 9 of the loess original sample. If the ice bag is damped, melted or leaked, the sealing door 14 can block the diffusion of moisture and other impurities, avoid contacting the loess original sample, so as to protect the sample from being soaked and contaminated, maintain the integrity and original characteristics of the sample, and ensure the accuracy of subsequent research.
[0037] As shown in the drawings, Figure 2 As shown in the drawings, in some embodiments, the limiting rod 16 is rotated to the middle of the blocking block 15 to overlap, so that the sealing door 14 is locked; even if affected by external forces such as vibration and collision during the movement and transportation of the device, the sealing door 14 will not be easily opened, the closed space of the ice bag in the loading box 8 is effectively maintained, the stability of the low-temperature environment is ensured, the ice bag is prevented from being damped or leaked, and then the loess original sample is protected from external interference.
