Description

Technical Field

[0001] The utility model belongs to the technical field of soil heavy metal detection, and in particular relates to a heavy metal detection device for soil remediation. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Soil heavy metal detectors are needed in soil remediation work. The soil heavy metal detectors on the market now need to carry small test tubes and solvents when in use. The test tubes and solvent tubes are easy to loosen during placement. At the same time, during transportation, the test tubes may be damaged by collision and the solvent tubes may be spilled due to bumps, affecting the normal use of the device.

[0003] In the prior art, a Chinese patent with a reference number of CN 213041845 U discloses an environmentally friendly soil heavy metal detection device for soil remediation, including a detection device body, a cover plate hinged on the top of the detection device body, and a restraining belt sewn on the surface of the cover plate, a limiting mechanism fixedly installed at the bottom right end of the detection device body, the limiting mechanism includes a fixing plate, and a cross frame is fixedly connected to the bottom end of the fixing plate. The utility model sets a limiting mechanism, places the test tube and the solvent tube in the grid formed by the cross frame and the vertical frame, and pushes the inner rod to move under the elastic force of the first spring. The inner rod pushes the connecting plate to move during the movement, and then the connecting plate clamps the test tube and the solvent tube to avoid collision and breakage of the test tube and splashing of the solvent tube during transportation.

[0004] The comparative document provides an environmentally friendly soil heavy metal detection device for soil remediation. However, when the above patent clamps the test tube and the solvent tube, since the connecting plate is a plate-like structure, the connecting plate can only clamp test tubes or solvent tubes of the same size, and the scope of use is small. Some tools used for soil detection (soil sampling, solution dripping, etc.) are not easy to clamp.

[0005] Therefore, a heavy metal detection device for soil remediation is proposed. Utility Model Content

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present invention provides a heavy metal detection device for soil remediation. Figure 1-4As shown, it includes an outer box body 1, the inner bottom of the outer box body 1 is fixedly connected to the inner box body 2 by screws, the outer box body 1 and the inner box body 2 are both hollow rectangular structures with open tops, and a first limiting plate 3 and a second limiting plate 4 are fixed to the inner wall of one side of the inner box body 2 by adhesive, the first limiting plate 3 is located above the second limiting plate 4, and the tops of the first limiting plate 3 and the second limiting plate 4 are both provided with limiting holes 5, and the inside of the limiting hole 5 is penetrated by a vertical rod 6, and the double limiting of the vertical rod 6 by the first limiting plate 3 and the second limiting plate 4 is realized to realize the two-point limiting of the vertical rod 6 in the vertical direction, further avoiding The vertical rod 6 is inclined, and a spring 7 is fixed to the bottom end of the vertical rod 6 by adhesive. The bottom end of the spring 7 and the inner bottom of the inner box body 2 are fixed by adhesive. A box cover 8 is hinged on the top of the inner box body 2. A heavy metal detector 9 is fixed by screws on the inner bottom of the outer box body 1 near one side of the inner box body 2. A soil heavy metal detection port, a display screen and buttons are provided on the top of the heavy metal detector 9. A box cover 10 is hinged on the top of the outer box body 1. The box cover 10 and the outer box body 1 are connected by a lock, and an inner groove is provided on the outer wall of one side of the box cover 10 near one side of the outer box body 1.

[0024] It should be noted that, since the existing soil heavy metal detection device can only clamp test tubes or solvent tubes of the same size, the scope of use is small, and some tools used for soil detection (soil sampling, solution dripping, etc.) are not convenient to clamp, the vertical rod 6 in the inner box body 2 that is not vertically squeezed by the test tube or solvent tube can be used to horizontally limit the test tube or solvent tube to avoid leakage or damage caused by horizontal shaking of the test tube or solvent tube. It can also limit the inserted test tubes or solvent tubes of different sizes, and can also limit some special-shaped tools to avoid shaking and collision of the device when carrying. The top of the test tube or solvent tube is squeezed by the box cover 8 to achieve vertical fixation of the test tube or solvent tube.

[0025] Specifically, in this embodiment, this scheme mainly includes a vertical rod 6. When carrying, the test tube and solvent tube required for soil heavy metal detection are placed in the inner box body 2. When placing, the test tube or solvent tube is vertically inserted into the inner box body 2, and the test tube or solvent tube contacts the vertical rod 6. The vertical rod 6 is squeezed and moves toward the bottom of the inner box body 2. Under the limitation of the limiting hole 5, the vertical rod 6 moves vertically downward, and the spring 7 at the bottom end of the vertical rod 6 is compressed. The vertical rod 6 that is not in contact with the test tube or solvent tube remains in its original state, so that the vertical rod 6 outside the test tube or solvent tube limits it to prevent the test tube or solvent tube from shaking horizontally. The box cover 8 is movable, and a plurality of neatly arranged vertical rods 6 can be used to limit the inserted test tubes or solvent tubes of different sizes, and can also limit some special-shaped tools to prevent the device from shaking and hitting when carried. After completing the limited placement of the items, the box cover 8 is closed, and the box cover 8 squeezes the top of the test tube or solvent tube to fix the test tube or solvent tube in the vertical direction. The box cover 8 is snap-fitted and fixed. When conducting soil heavy metal detection, the sampled soil and solvent are mixed and put into the soil heavy metal detection port on the heavy metal detector 9, and the required soil remediation method is formulated according to the type and content of heavy metals in the soil.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the top end of the vertical rod 6 does not exceed the top of the inner box body 2.

[0027] In this embodiment, space can be provided for the insertion of test tubes, solvent tubes or special-shaped tools, and space can also be provided for the vertical rod 6 to move up and down, thereby increasing the maximum descending position of the vertical rod 6.

[0028] In a further preferred embodiment of the present invention, Figure 4 As shown, the limiting holes 5 on the same position of the first limiting plate 3 and the second limiting plate 4 are on the same vertical line.

[0029] In this embodiment, the vertical movement of the vertical rod 6 can be limited to prevent the vertical rod 6 from tilting.
