Description

Technical Field

[0001] This utility model relates to deformation monitoring of structures, soil and rock masses, etc., and specifically to a measuring umbrella frame for a surface displacement observation pier. Background Technology

[0002] To monitor the deformation of structures, soil and rock masses, and to understand their operational status, observation piers are typically installed for surface deformation monitoring. The principle involves using measuring equipment such as total stations and theodolites at the working benchmark to observe prisms and targets erected on top of the observation pier at the measuring point, obtaining changes in the displacement of the measuring point, thereby monitoring the deformation of the monitored object.

[0003] Surface deformation monitoring is a field operation, greatly affected by weather. Measurements are prone to error under conditions of significant variation in sunlight, temperature, and other environmental factors. Therefore, relatively stable environmental conditions are required to ensure observation accuracy. Furthermore, total stations, theodolites, and other surveying equipment are precision instruments; they must be operated under umbrellas in rainy or sunny weather to prevent them from getting wet or exposed to direct sunlight, which could shorten their lifespan.

[0004] Umbrellas are one of the commonly used auxiliary tools for deformation monitoring. They can prevent direct sunlight from shining on the instruments and equipment, provide a more stable observation environment for the instruments, improve the accuracy and stability of measurement data, ensure the quality of results and work efficiency, and also protect the main body of the instruments in harsh weather conditions, thus extending the service life of the instruments.

[0005] However, when surveyors conduct observations, they typically need to repeatedly operate instruments, aim, and record data, making it impossible to simultaneously protect the instruments with an umbrella. Assigning a dedicated person to hold the umbrella not only increases costs but also easily leads to fatigue and increases labor intensity due to prolonged umbrella holding. Utility Model Content

[0006] The technical problem to be solved by this utility model is that, in the case of surface deformation monitoring requiring umbrella operation, but the observers cannot hold the umbrella at the same time, and holding the umbrella for a long time increases the labor intensity, this utility model provides a measuring umbrella frame for surface displacement observation pier.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A measuring umbrella frame for a surface displacement observation pier includes: a mounting nut fixedly connected to the observation pier, a transverse support rod threadedly connected to the mounting nut, a vertical support rod detachably connected to the transverse support rod, and an umbrella rod fixing clamp mounted on the upper end of the vertical support rod. The umbrella rod fixing clamp includes a first side clamp, a second side clamp, and a fastener. One end of the first side clamp and one end of the second side clamp are hinged to the vertical support rod, and the other end of the first side clamp and the other end of the second side clamp are fastened together by the fastener.

[0009] Thus, this utility model can be installed on the observation pier and the umbrella pole can be clamped by the umbrella pole fixing clip to achieve umbrella opening, thereby preventing the monitoring equipment from being rained on or exposed to the sun, and providing the instrument with a more stable observation environment.

[0010] A further improvement to the above solution is that the horizontal support rod and the vertical support rod are detachably connected via a pipe joint, the pipe joint having a first interface for connecting to the horizontal support rod and a second interface for connecting to the vertical support rod.

[0011] A further improvement to the above solution is that umbrella rod mounting grooves are provided opposite to each other in the first side clamp and the second side clamp.

[0012] A further improvement to the above scheme is that the observation pier is a reinforced concrete observation pier, and the mounting nuts are pre-embedded or drilled and buried on both sides of the upper part of the observation pier body.

[0013] A further improvement to the above solution is that the inner surfaces of both the first and second side clamps are provided with anti-slip pads.

[0014] A further improvement to the above solution is that the horizontal support rod and the vertical support rod are made of stainless steel tubing.

[0015] A further improvement to the above solution is that the umbrella pole fixing clip is made of ABS plastic.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) When working in the field, this utility model can be used to fix the umbrella on the observation pier to avoid direct sunlight on the instruments and equipment, provide a relatively stable observation environment for the instruments, improve the accuracy and stability of the observation data, and ensure the quality of measurement results and work efficiency.

[0018] 2) After adopting this utility model, there is no need for observers to hold umbrellas for the instruments, which reduces the labor intensity of personnel and saves costs.

[0019] 3) This utility model has a simple structure, is easy to install, easy to carry, and can be used repeatedly. Attached Figure Description

One end of the first side clip 31 and one end of the second side clip 32 are hinged together by the vertical support rod 23, and the other ends of the first side clip 31 and the second side clip 32 are fastened together by the fastener 33. Umbrella pole mounting grooves 34 are provided opposite to each other in the first side clip 31 and the second side clip 32. Loosening the fastener 33 allows the umbrella pole to be inserted into the umbrella pole mounting groove 34, and then tightening the fastener 33 locks the umbrella pole in place, thus supporting the umbrella.

[0031] To ensure support stability, anti-slip pads are provided on the inner surfaces of both the first side clamp 31 and the second side clamp 32.

[0032] The horizontal support rod 22 and the vertical support rod 23 are preferably made of stainless steel tubing. The umbrella pole fixing clip 3 is preferably made of ABS plastic.

[0033] The following describes a specific application of this utility model:

[0034] For surface deformation monitoring of a landslide, five displacement observation piers and two working base observation piers are set up. This utility model is used for surface displacement observation.

[0035] All observation piers 1 are frustum-shaped reinforced concrete observation piers. During the concrete pouring of the pier body, on both sides of observation pier 1 perpendicular to the free face of the slope, at a position 200mm below the top of observation pier 1, a 60mm long M16 mounting nut 11 is pre-embedded. The mounting nuts 11 are pre-made stainless steel. The mounting nuts 11 should be protected during pre-embedding to prevent grout from entering.

[0036] The frame 2 is made of stainless steel tubing. The horizontal support rod 22 is 200mm long, and one end is a 60mm long threaded rod 21 that matches the mounting nut 11. The vertical support rod 23 is 300mm long, and the end is equipped with an ABS plastic umbrella pole fixing clip 3.

[0037] During measurement, the observer sets up the instrument on the observation pier at the working base point. Based on the solar direction and the location of the measuring point, the threaded rod 21 on the horizontal support rod 22 is screwed into the pre-embedded mounting nut 11 on one side of the observation pier 1. Then, the vertical support rod 23 and the umbrella pole fixing clamp 3 are installed. The umbrella pole is clamped to a suitable height using the umbrella pole fixing clamp 3, and the fasteners 33 are tightened to secure the umbrella to the frame 2. The observation work can then commence. After the measurement is completed, the frame 2 is disassembled, and the measuring equipment is stored away, thus completing the measurement work on the observation pier at the working base point.

[0038] This utility model has a simple structure, is lightweight, flexible in assembly and disassembly, and easy to use. When conducting field measurements, there is no need to assign a dedicated person to hold an umbrella, which reduces the labor intensity of the surveyors, lowers costs, and improves work efficiency.
