Description

Technical Field

[0001] This utility model relates to the field of dam safety monitoring technology, and in particular to a novel deformation lidar mounting bracket. Background Technology

[0002] In accordance with the overall requirements of the Ministry of Water Resources for the construction of smart water conservancy, and focusing on the main tasks of water conservancy project operation management, supervision and management, and collaborative management, we will use digital means such as the Internet of Things, big data, and artificial intelligence to build a digital platform for water conservancy project operation management, so as to fully achieve the goal of intelligent and modern operation management of water conservancy projects, further ensure the safe operation of water conservancy projects, and give full play to the benefits of water conservancy projects.

[0003] Hydraulic structures, due to the properties of their own materials, will deform due to soil consolidation and rheological changes in the rockfill. Excessive deformation may lead to problems such as uneven settlement and cracks. Surface deformation of hydraulic structures is the most direct manifestation of this deformation, therefore, surface deformation monitoring of hydraulic structures is necessary.

[0004] In my country, most large and medium-sized reservoirs are equipped with surface deformation monitoring facilities (observation piers), and manual observations are conducted periodically using total stations and levels. For dams with shorter lengths and stable bedrock on both banks, manual observation of surface deformation using these piers generally meets the required accuracy standards; however, for longer dams, the accuracy is relatively low. The frequency of manual observations is low and greatly affected by weather conditions, making it difficult to promptly grasp the dam's operational status. Some reservoirs have implemented automated surface deformation monitoring, such as using hydrostatic levels for automatic settlement monitoring and tension line instruments for automatic horizontal displacement monitoring. While hydrostatic levels and tension line instruments provide sufficient accuracy and can be automated, their deployment requires suitable terrain and geological conditions, resulting in high installation costs, high maintenance requirements, and the instruments are prone to damage and have a short lifespan. Therefore, their widespread application is not yet feasible.

[0005] The use of lidar technology to measure the external deformation of dams in water conservancy projects is gradually being adopted in the field of deformation monitoring. Its main application principle involves installing a lidar transmitter to continuously emit microwave signals towards the target. These signals are reflected when they encounter objects on the ground, and some of the reflected signals return to the monitoring system and are received. The received signals contain information such as the target object's distance, velocity, and orientation. By comparing this with the initially received signal, the deformation of the target object can be calculated.

[0006] Water conservancy projects can achieve large-scale deformation monitoring through networking or mobile monitoring of multiple radar systems. A single radar can reach a range of 5 kilometers, with no angle limitations on elevation or depression, observing points within a 30-degree angle range. Considering the unique characteristics of water conservancy projects, such as high dams, long dam crests, and long dikes, a single radar transmitter cannot monitor all points. Therefore, multiple radar transmitters need to be deployed. However, deploying multiple transmitters requires constructing multiple installation supports and may involve land acquisition issues, making it complex and costly.

[0007] Therefore, this case is brought. Utility Model Content

[0008] The purpose of this utility model is to provide a novel deformation lidar mounting bracket to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] A novel deformation lidar mounting bracket includes, from bottom to top, a forced centering chassis and several layers of brackets. The bottom of the forced centering chassis is fixed to the observation pier by a connector. A protruding stud is provided at the center of its top surface. A protruding stud is provided at the center of the top surface of the brackets. A threaded hole is provided at the center of the bottom surface of the brackets, which can be threadedly connected to stud one or stud two.

[0011] The outer diameter of the lower support is larger than that of the upper support, and each support has several protruding studs arranged on the top edge, which are used to connect the deformation lidar.

[0012] Furthermore, the second stud at the center of the topmost support is used to connect the lightning rod.

[0013] Furthermore, it includes a stud cap that can be threadedly connected to the stud triplet, the stud cap comprising a counterweight cap and a protective cap, the counterweight cap being used to balance the weight of the deformation lidar, and the protective cap being used to protect the stud triplet.

[0014] Furthermore, the support is a cylindrical or polygonal column.

[0015] The advantages of this utility model are:

[0016] 1. By setting up lidar points at different heights, it is possible to cover as many deformation observation points as possible, reduce the number of lidar point installation locations, and reduce land acquisition and financial pressure.

[0017] 2. Different sizes of mounting brackets are used to connect the bolts, so that different lidar points can be set at different heights. The bolts and screw holes are produced in a matching set to facilitate construction and installation. At the same time, the top bolts are connected to the lightning rod to provide lightning protection for the entire mounting bracket structure.

[0018] 3. The installation brackets of different sizes can be set up to meet the needs of various water conservancy construction projects, which to a certain extent broadens the applicability of the equipment. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the embodiments. It should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicated by the accompanying drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0030] This embodiment proposes a novel mounting bracket for deformation lidar, such as... Figures 1 to 7 As shown, from bottom to top, it includes a forced centering chassis 2, a first-layer support 4, and a second-layer support 4. For ease of explanation, this embodiment only uses two layers of support 4, but in practice, more layers of support 4 can be used to install more deformation lidars 5, depending on engineering requirements. In this embodiment, the support 4 is cylindrical, but it can also be a quadrilateral column, an octagonal column, etc.

[0031] The bottom of the forced centering chassis 2 is fixed to the observation pier 1 via a connector 3. The forced centering chassis 2 and its connection structure to the observation pier 1 are existing technologies and will not be described in detail here. A protruding stud 201 is provided at the center of the top surface of the forced centering chassis 2. A protruding stud 401 is provided at the center of the top surface of each layer of support 4, and a threaded hole 402 is provided at the center of the bottom surface of the support 4 for threaded connection with either stud 201 or stud 401. Simultaneously, the outer diameter of the lower layer of support 4 is larger than that of the upper layer of support 4, and several protruding studs 403 are arranged along the edge of the top surface of each layer of support 4. These studs 403 are used to connect to the deformation lidar 5. Figure 5 As shown, in this embodiment, two symmetrical studs 403 are arranged on the top edge of the bracket 4, but they can also be arranged as follows, depending on the engineering requirements. Figure 6 The four studs shown are 3403, or even more.

[0032] During installation, the centering chassis 2 is forcibly fixed to the observation pier 1 via the connector 3; for example... Figure 4 As shown, the first-layer bracket 4 is threadedly connected to the stud 201 on the forced centering chassis 2 through the screw hole 402 on its bottom surface; as Figure 3 As shown, the second-layer bracket 4 is threadedly connected to the stud 401 on the first-layer bracket 4 through the screw hole 402 on its bottom surface. The stud 401 at the center of the top surface of the second-layer bracket 4 can be threadedly connected to the lightning rod 6, which plays a role in lightning protection for the entire mounting bracket 4 structure.

[0033] When using, such as Figure 8As shown, the deformation lidar 5 is fixedly connected to the studs 403 of each layer of the support 4. By setting lidar points at different heights, more deformation observation points can be covered as much as possible, reducing the number of lidar point installation locations, reducing land acquisition and financial pressure, and also facilitating construction and installation.

[0034] by Figure 8 Taking the first layer of support 4 as an example, a deformation lidar 5 is installed on one side, while the other side is not. This may cause uneven stress on the overall support structure 4. As an improvement, in this embodiment, support 4 also includes stud caps 7, which include a counterweight cap and a protective cap. The counterweight cap is used to balance the weight of the deformation lidar 5, and the protective cap is used to protect the stud 403. Figure 8 In the first layer of support 4, on the studs 403 where the deformation lidar 5 is not installed, a counterweight cap can be screwed on (the counterweight cap can be made to match the weight of the deformation lidar 5), thereby achieving balance on both sides of the first layer of support 4. When none of the studs 403 on a certain layer of support 4 are equipped with deformation lidar 5, or when the deformation lidar 5 is symmetrically installed on that layer (e.g., ...), the balance is achieved. Figure 6 In the middle, the left and right studs 403 are equipped with deformation lidar 5, while the front and rear studs 403 are not equipped with deformation lidar 5. Then, the studs 403 on the support 4 of this layer that are not equipped with deformation lidar 5 can be screwed on with protective caps to protect the studs 403, such as rust prevention.

[0035] The above embodiments are only used to explain the concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial modifications made to the present invention using this concept should fall within the protection scope of the present invention.
