Description

Technical Field

[0001] This utility model relates to the field of geological engineering and environmental monitoring technology, and in particular to a fixed structure for monitoring equipment in permafrost areas. Background Technology

[0002] In high-altitude permafrost regions, such as the Qinghai-Tibet Plateau, the Arctic region, and permafrost zones, various monitoring instruments and sensors are typically buried or installed in order to conduct long-term monitoring of geological parameters such as ground temperature, displacement, settlement, and water content.

[0003] However, in existing technologies, traditional monitoring equipment is often fixed by methods such as cement pouring, driving in metal brackets, or fixing with simple wooden stakes. However, the frozen soil undergoes periodic frost heave and thaw settlement with temperature changes, which can easily lead to loosening or displacement of the fixing structure. In addition, some structures lack pull-out resistance design and are easily lifted or tilted under the expansion of frozen soil. Furthermore, some structures have a single function and are cumbersome to install, making them inconvenient for rapid deployment and thus have certain limitations. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art: traditional methods of fixing monitoring equipment often use cement pouring, metal bracket driving, or simple wooden stake fixing, but the frozen soil undergoes periodic frost heave and thaw settlement with temperature changes, which can easily lead to loosening or displacement of the fixing structure. In addition, some structures lack pull-out resistance design and are easily lifted or tilted under the action of frozen soil expansion. Furthermore, some structures have simple functions and are cumbersome to install, making it inconvenient to deploy quickly, and thus have certain limitations.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fixing structure for a monitoring device in permafrost areas, comprising: a support rod, a mounting plate, and a mounting plate fixedly disposed on the top surface of the support rod; further comprising:

[0011] Preferably, the fixing structure further includes: a sliding groove is formed on the surface of the multiple connecting rods near the support rod, and a multiple positioning holes are formed on one side surface of the connecting rod.

[0012] The technical effect of adopting the above-mentioned further solution is that the groove opened on the second surface of the connecting rod facilitates the movement of the parts, and the positioning hole on the surface facilitates the positioning of the parts.

[0013] Preferably, a movable plate is movably embedded in the bottom inner wall of the second connecting rod via a circumferential bearing, and anchor rods are threaded into the inner walls of multiple movable plates.

[0015] Preferably, an anti-pull-out ring is provided in the middle of the plurality of anchor rods, and the anti-pull-out ring is an annular flange structure.

[0016] The technical effect of adopting the above-mentioned further solution is that the pull-out ring set on the surface of the anchor rod is used to enhance the anchoring force and prevent it from floating due to frost heave. At the same time, the pull-out ring is a ring flange structure that is embedded in the frozen soil layer to form a resistance surface.

[0017] Preferably, the bottom surface of the anchor rod is provided with a tapered portion, and the surface of the tapered portion is provided with anti-slip texture.

[0023] Preferably, locating pins are provided symmetrically on one side surface of the plurality of connecting plates, and one end of the plurality of locating pins is movably embedded inside the locating hole.

[0024] The technical effect of adopting the above-mentioned further solution is that when the positioning pin on the surface of the connecting plate is embedded in the positioning hole, it provides positioning for the slider, thereby providing locking support.

[0025] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0026] 1. In this utility model, by unfolding the connecting rod two inside the groove, the slider moves along the inside of the groove. When the connecting plate on the surface of the spring is pulled, the positioning pin disengages from the inside of the positioning hole, thereby adjusting the position of the slider inside the groove. This allows the connecting rod one to adjust the tilt angle inside the groove with respect to the installed round shaft. At the same time, the angle of the connecting rod two is locked, thereby enabling the monitoring equipment installed on the surface of the mounting plate to meet the installation requirements of different heights and improving the applicability of the device.

[0027] 2. In this utility model, when the anchor rod inside the rotating movable plate is inserted into the frozen soil by means of the conical part, the anti-slip texture on the surface improves the insertion stability, and the pull-out ring is a ring flange structure that is embedded in the frozen soil layer to form a resistance surface to enhance the anchoring force and prevent floating due to frost heave. At the same time, the anchor rod can be used in conjunction with the heat insulation sleeve to isolate the external environment from the thermal disturbance of the frozen soil around the anchor rod and reduce the impact of freeze-thaw.

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0036] Example 1, such as Figure 1-4 As shown, this utility model provides a fixing structure for a monitoring device in permafrost areas, including: a support rod 1 with a mounting plate 101 fixedly mounted on its top for supporting external monitoring equipment; multiple slots 102 are formed on the outer surface of the support rod 1, and a connecting rod 1022 is movably embedded in each slot 102 via a round shaft, with the multiple connecting rods 1022 arranged in a triangle to form a stable adjustment mechanism; by rotation or displacement adjustment, the support structure can adapt to installation requirements at different angles and directions; at the same time, a connecting rod 2 103 is also provided on the side of the slot 102 near the mounting plate 101, which is also movably connected via a round shaft, and is used to cooperate with the connecting rod 1022 after adjustment to achieve structural locking, ensuring stability and safety during use.

[0037] In this embodiment, by unfolding the connecting rod 103 inside the slot 102, the slider 1023 moves along the inside of the slide groove 1031. When the connecting plate 1025 on the surface of the spring 1024 is pulled, the positioning pin 1026 disengages from the inside of the positioning hole 1032, thereby adjusting the position of the slider 1023 inside the slide groove 1031. This allows the connecting rod 1022 to adjust its tilt angle inside the slot 102 with the installed round shaft, while locking the angle of the connecting rod 103. This enables the monitoring equipment mounted on the surface of the mounting plate 101 to meet different height installation requirements, improving the applicability of the device.

[0038] Example 2, as Figure 1-4As shown, the connecting rod 103 in the fixed structure has a sliding groove 1031 on the side near the support rod 1, and slides with the slider 1023 at the end of the connecting rod 1022. The slider 1023 is connected to the connecting plate 1025 through the spring 1024. The connecting plate 1025 is provided with a positioning pin 1026, which can be inserted into the positioning hole 1032 on the connecting rod 103 to achieve structural locking. At the same time, the bottom of the connecting rod 103 is movably connected to the movable plate 1033 through the bearing. The inner wall of the movable plate 103 is threadedly connected to the anchor rod 104. The anchor rod 104 has an anti-pull-out ring 1041 in the middle, which is embedded in the frozen soil layer to form a resistance surface. The bottom is a tapered part 1042 with anti-slip texture to enhance the connection strength with the ground or the mounting base.

[0039] In this embodiment, when the anchor rod 104 inside the rotating movable plate 1033 is inserted into the frozen soil by means of the tapered part 1042, and the anti-slip texture on the surface improves the insertion stability. At the same time, the pull-out ring 1041 is a ring flange structure that is embedded in the frozen soil layer to form a resistance surface, which is used to enhance the anchoring force and prevent floating due to frost heave. Meanwhile, the anchor rod 104 can be used in conjunction with the heat insulation sleeve to isolate the external environment from the thermal disturbance of the frozen soil around the anchor rod 104 and reduce the impact of freeze-thaw.

[0040] Working principle: In use, by unfolding the connecting rod 103 inside the slot 102, the slider 1023 moves along the inside of the slide groove 1031. When the connecting plate 1025 on the surface of the spring 1024 is pulled, the positioning pin 1026 disengages from the inside of the positioning hole 1032, thereby adjusting the position of the slider 1023 inside the slide groove 1031. This allows the connecting rod 1022 to adjust its tilt angle inside the slot 102 around the installed circular shaft. At the same time, the angle adjusted by the connecting rod 103 is locked, thereby allowing the monitoring device installed on the surface of the mounting plate 101 to be monitored. The equipment meets installation requirements at different heights, improving the applicability of the device. In addition, when the anchor rod 104 inside the rotating movable plate 1033 is inserted into the frozen soil with the help of the tapered part 1042, the anti-slip texture on the surface improves the insertion stability. At the same time, the pull-out ring 1041 is a ring flange structure that is embedded in the frozen soil layer to form a resistance surface to enhance the anchoring force and prevent floating due to frost heave. The anchor rod 104 can also be used with the insulation sleeve for auxiliary purposes to isolate the external environment from the thermal disturbance of the frozen soil around the anchor rod 104 and reduce the impact of freeze-thaw.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
