Description

Technical Field

[0001] This utility model relates to the field of soil pollution technology, specifically to a sampling and storage device for soil pollution. Background Technology

[0002] Soil pollutants can be broadly classified into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, radioactive compounds of cesium and strontium, and compounds containing arsenic, selenium, and fluorine. To remediate soil, samples are taken and then stored in sampling bottles.

[0003] A search revealed a Chinese patent document disclosing a soil pollution sampling and storage device [Announcement No.: CN214452990U]. This device includes a storage box, with a lid hinged to the top left side of the box via a pin. A humidifier is fixedly connected to the bottom of the lid. Symmetrical partition plates are fixedly connected to the inner top wall of the storage box. Symmetrical sliding grooves are formed on the inner side wall of the storage box, and a placement plate is engaged within each groove. Symmetrical threaded holes are formed on the upper surface of the placement plate, and equally spaced perforations are formed on the upper surface of the threaded holes. A symmetrical sealing sleeve is fixedly embedded on the upper surface of the placement plate. This soil pollution sampling and storage device, through the sliding grooves on the inner wall of the storage box and their cooperation with the placement plates, facilitates smoother vertical movement of the placement plates, enabling the placement plates to move the soil vertically. This solves the problem of inconvenient and cumbersome removal of the stored soil.

[0004] Soil itself is adhesive, especially some moist soil, which can easily stick to the inner wall of the sampling bottle, making it difficult to remove the soil for testing later.

[0005] To address this issue, we propose a soil pollution sampling and storage device. Utility Model Content

[0006] The purpose of this invention is to provide a sampling and storage device for soil pollution, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sampling and storage device for soil pollution, comprising a bottle body and a bottle cap, wherein the bottle cap is threadedly connected to the top of the bottle body, a top-out plate is provided inside the bottle body, a base is fixedly connected to the bottom of the bottle body, and a top-out mechanism is provided at the bottom of the base.

[0008] A puncture mechanism is fixedly mounted on the top plate.

[0009] Preferably, the ejection mechanism includes a threaded rod threaded to the bottom of the base, the top of the threaded rod extending into the interior of the bottle, a bearing being provided at the bottom of the ejection plate and rotatably connected to the top of the threaded rod via the bearing, and a threaded hole being provided at the bottom of the base for use with the threaded rod.

[0010] Preferably, the puncture mechanism includes a support ring disposed at the bottom of the ejector plate, a puncture needle is fixedly connected to the top of the support ring, and a through hole for use with the puncture needle is provided on the top of the ejector plate.

[0011] Two extrusion rods are fixedly connected to the circumferential side of the threaded rod, an extrusion block that works with the extrusion rods is fixedly connected to the bottom of the support ring, and two springs are fixedly connected to the top of the support ring, with the top of the springs fixedly connected to the bottom of the support ring.

[0012] Preferably, the number of puncture needles is several, and they are evenly distributed in a ring on the top of the shell.

[0013] Preferably, both sides of the extrusion block are sloped.

[0014] Preferably, a screwing block is fixedly connected to the bottom of the threaded rod, and an anti-slip groove is provided on the circumferential side of the screwing block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting up an ejection mechanism, when soil needs to be removed, the user can open the bottle by twisting the cap, and then rotate the twisting block. The twisting block will drive the threaded rod to rotate in the threaded hole. The threaded rod will gradually move upward, and at the same time drive the bearing and ejection plate to move upward. As the ejection plate moves upward, it will push out the soil sample in the bottle, thereby making it easy to remove the soil sample.

[0017] 2. This utility model, by setting a piercing mechanism, enables the extrusion rod to rotate simultaneously with the threaded rod. When the surface of the extrusion rod contacts the inclined part of the extrusion block, the extrusion block will move upward due to the extrusion, which in turn drives the support ring and the piercing needle to move upward. When the extrusion rod moves to a point where it no longer contacts the extrusion block, the elastic force generated by the spring will drive the support ring and the piercing needle to move downward. This cycle repeats, and the piercing needle will pierce a hole in the compacted soil, reducing the resistance when the soil is pushed out and facilitating soil removal. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1 - Figure 4 As shown,

[0025] Example 1:

[0026] A soil pollution sampling and storage device includes a bottle body 1 and a bottle cap 2. The bottle cap 2 is threaded to the top of the bottle body 1. A top plate 3 is provided inside the bottle body 1. A base 4 is fixedly connected to the bottom of the bottle body 1. A top ejection mechanism is provided at the bottom of the base 4.

[0027] The puncture mechanism is fixedly mounted on the top plate 3.

[0028] The ejection mechanism includes a threaded rod 5 that is threaded to the bottom of the base 4. The top of the threaded rod 5 extends into the interior of the bottle body 1. A bearing 6 is provided at the bottom of the ejection plate 3, and the bearing 6 is rotatably connected to the top of the threaded rod 5. A threaded hole 7 is provided at the bottom of the base 4 to cooperate with the threaded rod 5.

[0029] In this embodiment, considering the adhesive nature of soil, especially some moist soil, it is easy to stick to the inner wall of the sampling bottle, making it difficult to remove the soil for testing. Therefore, by setting up an ejection mechanism, when soil needs to be removed, the user can open the bottle body 1 by twisting the bottle cap 2, and then rotate the twisting block 14. The twisting block 14 will drive the threaded rod 5 to rotate in the threaded hole 7. The threaded rod 5 gradually moves upward, and at the same time, it drives the bearing 6 and the ejection plate 3 to move upward. As the ejection plate 3 moves upward, it will push out the soil sample in the bottle body 1, thereby facilitating the removal of the soil sample.

[0030] The bottom of the threaded rod 5 is fixedly connected to a screwing block 14, and the circumferential side of the screwing block 14 is provided with an anti-slip groove 15.

[0031] In this embodiment, by setting the screwing block 14 and the screwing groove, a gripping point can be provided for the user when the user needs to rotate the threaded rod 5, which facilitates driving.

[0032] Example 2:

[0033] Based on Embodiment 1, in this embodiment, the ejection mechanism can control the ejection plate 3 to move upward and eject the soil in the bottle 1, so as to facilitate the removal of the soil. However, considering that the soil will be compressed and compacted during the ejection process, the resistance during ejection will increase, which will also make it difficult to remove the soil. In this application, the puncture mechanism includes a support ring 8 set at the bottom of the ejection plate 3, and a puncture needle 9 is fixedly connected to the top of the support ring 8. The top of the ejection plate 3 is provided with a through hole 10 that works with the puncture needle 9.

[0034] Two extrusion rods 11 are fixedly connected to the circumferential side of the threaded rod 5. An extrusion block 12 that works with the extrusion rods 11 is fixedly connected to the bottom of the support ring 8. Two springs 13 are fixedly connected to the top of the support ring 8. The top of the springs 13 is fixedly connected to the bottom of the support ring 8.

[0035] In this embodiment, by setting a piercing mechanism, when the threaded rod 5 rotates, it will drive the extrusion rod 11 to rotate. When the surface of the extrusion rod 11 contacts the inclined part of the extrusion block 12, the extrusion block 12 will move upward due to the extrusion, and at the same time drive the support ring 8 and the piercing needle 9 to move upward. When the extrusion rod 11 moves to the point where it no longer contacts the extrusion block 12, the elastic force generated by the spring 13 will drive the support ring 8 and the piercing needle 9 to move downward. This cycle continues, and the piercing needle 9 will pierce a hole in the compacted soil, so that the resistance when the soil is pushed out is reduced, thus facilitating the removal of the soil.

[0036] It should be noted that when the ejector plate 3 comes into contact with the soil, the ejector plate 3 will be subject to resistance, so the ejector plate 3 will not rotate synchronously with the threaded rod 5.

[0037] The number of puncture needles 9 is several, and they are evenly distributed in a ring at the top of the shell.

[0038] In this embodiment, by setting puncture needles 9, the multiple puncture needles 9 can be designed in a ring shape to increase the resistance encountered when pushing out of the soil by piercing multiple annular holes in the soil.

[0039] Both sides of the extrusion block 12 are sloping.

[0040] In this embodiment, by setting the extrusion block 12, when the surface of the extrusion rod 11 contacts the sloping part of the extrusion block 12, the extrusion block 12 will move upward due to the extrusion effect, thus playing a transmission role.

[0041] Working principle: When soil needs to be removed, the user can open the bottle body 1 by unscrewing the cap 2, and then rotate the screwing block 14. The screwing block 14 will drive the threaded rod 5 to rotate in the threaded hole 7. The threaded rod 5 gradually moves upward, and at the same time drives the bearing 6 and the ejector plate 3 to move upward. As the ejector plate 3 moves upward, it will push out the soil sample in the bottle body 1, thereby realizing the function of easily removing the soil sample.

[0042] As the threaded rod 5 rotates, it drives the extrusion rod 11 to rotate as well. When the surface of the extrusion rod 11 contacts the inclined part of the extrusion block 12, the extrusion block 12 will move upward due to the extrusion, which in turn drives the support ring 8 and the puncture needle 9 to move upward. When the extrusion rod 11 moves to a point where it no longer contacts the extrusion block 12, the elastic force generated by the spring 13 will drive the support ring 8 and the puncture needle 9 to move downward. This cycle repeats, and the puncture needle 9 will pierce holes in the compacted soil, reducing the resistance when the soil is pushed out and making it easier to remove the soil.
