Description

Technical Field

[0001] The utility model relates to the technical field of engineering monitoring, in particular to a monitoring device with a movable monitoring point. Background Art

[0002] When conducting safety monitoring, it is generally necessary to set up monitoring points at the location to be monitored, and judge the stability and safety of the location to be monitored by monitoring the monitoring points.

[0003] As the monitoring time goes by (especially for safety monitoring with a longer period, such as hydropower station dams, open-pit mine high slope safety monitoring and other fields), obstacles that affect monitoring may appear in the local area around the monitoring point.

[0004] For example, during the construction process, there are usually cross-operations or temporary buildings, which cause temporary obstructions and affect the monitoring of the monitoring points. In this case, the buildings in the monitoring line of sight cannot be cleared, and the monitoring of the monitoring point here will generally be abandoned, making it impossible to obtain the monitoring data of this monitoring point.

[0005] The other is that in the initial stage of monitoring, the monitoring line of sight is not blocked, but in the long-term monitoring process measured in years, there may be obstructions such as grass, leaves, branches, etc. in the monitoring line of sight, resulting in inaccurate monitoring data. This generally requires manual processing by personnel along the monitoring line of sight, which is time-consuming and labor-intensive on the one hand, and dangerous on the other hand, making actual monitoring more difficult.

[0006] Therefore, obstacles appearing in the local area around the monitoring point, causing the monitoring point to be blocked and resulting in monitoring difficulties, is a technical problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a monitoring device for a movable monitoring point. When the monitoring point prism is blocked, the mobile point monitoring prism is moved to an unblocked position, the mobile point monitoring prism is rotated to align the mobile point monitoring prism with the monitoring instrument, and the mobile point monitoring prism is monitored. According to the swing angle of the mobile point monitoring prism around the vertical support rod and the relative position relationship between the mobile point monitoring prism and the monitoring point prism, the monitoring data of the mobile point monitoring prism can be planned to the monitoring point prism, thereby indirectly realizing the monitoring of the monitoring point.

[0008] In response to the above technical problems, the technical solution provided by the utility model is a monitoring device for a movable monitoring point, comprising a vertical support rod, a monitoring point prism is arranged on the top of the vertical support rod, a horizontal circular dial is coaxially fixedly mounted on the vertical support rod, and also includes an auxiliary monitoring mechanism, the auxiliary monitoring mechanism includes a mobile point monitoring prism, and the mobile point monitoring prism can rotate vertically and make circular motion around the vertical support rod.

[0009] Furthermore, the auxiliary monitoring mechanism also includes a vertical moving point support shaft, the lower end of the moving point support shaft is slidably matched with the circular scale plate, and the moving point support shaft can make circular motion around the vertical support rod, and the moving point monitoring prism is rotatably set at the upper end of the moving point support shaft.

[0010] Furthermore, the auxiliary monitoring mechanism also includes a horizontal connecting rod arranged in parallel on the upper side of the circular dial, one end of the horizontal connecting rod is rotatably matched with the vertical support rod, and the other end is fixedly connected to the moving point support shaft.

[0011] Further, the moving point support shaft is arranged close to the outer circumference of the circular scale plate.

[0012] Furthermore, a scale pointer is arranged at the lower end of the moving point support shaft, and the scale pointer is slidably arranged on the circular scale plate.

[0013] Furthermore, the scale pointer is parallel to the horizontal connecting rod.

[0014] Further, the rotation axis of the moving point monitoring prism is colinear with the axis of the moving point supporting shaft.

[0015] Furthermore, a concrete foundation is provided at the lower end of the vertical support rod.

[0016] Furthermore, a horizontal cross bar is fixedly mounted on the lower end of the vertical support rod, and the horizontal cross bar is buried in the concrete foundation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) When the monitoring point is partially blocked, the monitoring point prism is blocked. At this time, by rotating the horizontal connecting rod, the mobile point monitoring prism is made to move in a circle around the vertical support rod, and then the mobile point monitoring prism can be moved to an unblocked position. The mobile point monitoring prism is rotated to align the mobile point monitoring prism with the monitoring instrument, and the mobile point monitoring prism is monitored. According to the swing angle of the mobile point monitoring prism around the vertical support rod and the relative position relationship between the mobile point monitoring prism and the monitoring point prism, the monitoring data of the mobile point monitoring prism can be planned to the monitoring point prism, thereby indirectly realizing the monitoring of the monitoring point.

[0019] (2) Using the graduated pointer, it is easy to observe the swing angle of the moving point monitoring prism around the vertical support rod.

[0020] (3) The rotation axis of the mobile point monitoring prism is colinear with the axis of the mobile point support shaft, which facilitates the planning of the monitoring data of the mobile point monitoring prism to the monitoring point.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0027] refer to Figure 1 to Figure 2 The utility model provides a monitoring device for a movable monitoring point, including a vertical support rod 2, a monitoring point prism 1 is arranged on the top of the vertical support rod 2, a horizontal circular scale plate 10 is coaxially fixedly installed on the vertical support rod 2, and also includes an auxiliary monitoring mechanism 6, the auxiliary monitoring mechanism 6 includes a movable point monitoring prism 4, and the movable point monitoring prism 4 can rotate vertically and make a circular motion around the vertical support rod 2.

[0028] Specifically, Figure 1 As shown, the auxiliary monitoring mechanism 6 also includes a vertical moving point support shaft 5, which is arranged parallel to the vertical support rod 2, the lower end of the moving point support shaft 5 is slidably matched with the circular dial 10, and the moving point support shaft 5 can make a circular motion around the vertical support rod 2, and the moving point monitoring prism 4 is rotatably set at the upper end of the moving point support shaft 5.

[0029] Preferably, the moving point support shaft 5 is arranged close to the outer periphery of the circular dial 10, which can relatively increase the rotation range of the moving point support shaft 5 around the vertical support rod 2, thereby increasing the monitorable range of the moving point monitoring prism 4 and facilitating avoiding the blocked range.

[0030] like Figure 1 As shown, in this embodiment, the auxiliary monitoring mechanism 6 also includes a horizontal connecting rod 3 arranged in parallel on the upper side of the circular scale plate 10, one end of the horizontal connecting rod 3 is rotatably matched with the vertical support rod 2, and the other end is fixedly connected to the moving point support shaft 5, and the lower end of the moving point support shaft 5 abuts against the upper side surface of the circular scale plate 10, so that the horizontal connecting rod 3 can easily drive the moving point support shaft 5 to rotate around the vertical support rod 2. Of course, in other embodiments, the horizontal connecting rod 3 may not be provided. In this case, an annular groove may be provided on the upper side surface of the circular scale plate 10, and the vertical cross-section of the annular groove is an inverted T-shaped. A slider is slidably provided in the annular groove, and the lower end of the moving point support shaft 5 is fixedly connected to the slider, so that the moving point support shaft 5 can also drive the moving point monitoring prism 4 to make a circular motion around the vertical support rod 2.

[0031] In this embodiment, if Figure 1 , 2 As shown, the upper side of the circular scale plate 10 is provided with a scale 9, specifically, the scale 9 of the circular scale plate 10 is equally divided into 360 parts, each part is one degree. Preferably, a scale pointer 11 is provided at the lower end of the moving point support shaft 5, and the scale pointer 11 is slidably arranged on the circular scale plate 10, and the scale pointer 11 is arranged parallel to the horizontal crossbar 7, so that by observing the overlap position of the scale pointer 11 on the circular scale plate 10 and the scale 9, it is convenient to obtain the rotation angle of the moving point monitoring prism 4 around the vertical support rod 2, thereby facilitating the calculation of the orientation of the moving point monitoring prism 4 and the calculation of the coordinates of the moving point monitoring prism 4.

[0032] In this embodiment, if Figure 1 , 2 As shown, the vertical center line of the monitoring point prism 1 is collinear with the axis of the vertical support rod 2. The rotation axis of the mobile point monitoring prism 4 is collinear with the axis of the mobile point support shaft 5, and the projections of the two on the horizontal plane fall on the end point of the scale pointer 11. This makes it easy to calculate the positional relationship between the mobile point monitoring prism 4 and the monitoring point prism 1, and then to plan the monitoring data of the mobile point monitoring prism 4 to the monitoring point. Of course, in other embodiments, when meeting actual usage requirements, the rotation axis of the mobile point monitoring prism 4 and the axis of the mobile point support shaft 5 may not be collinear. At this time, during actual monitoring, it is necessary to combine the monitoring data of the mobile point monitoring prism 4 with the positional relationship between the rotation axis of the mobile point monitoring prism 4 and the axis of the mobile point support shaft 5, and then combine the positional relationship between the mobile point monitoring prism 4 and the monitoring point prism 1, so as to achieve indirect monitoring of the monitoring point.

[0033] Preferably, in this embodiment, Figure 1 As shown, a concrete foundation 8 is provided at the lower end of the vertical support rod 2, and a horizontal cross bar 7 is fixedly installed at the lower end of the vertical support rod 2, and the horizontal cross bar 7 is buried in the concrete foundation 8. This makes it easy to firmly place the vertical support rod 2 in a vertical state and keep the support stable.

[0034] Working process of this application:

[0035] When the surroundings of the monitoring point prism 1 are partially or completely blocked and the monitoring point prism 1 cannot be used for monitoring, the staff rotates the horizontal connecting rod 3 to make the mobile point monitoring prism 4 move in a circle around the vertical supporting rod 2 until the mobile point monitoring prism 4 is moved to an unobstructed position, rotates the mobile point monitoring prism 4 to align the mobile point monitoring prism 4 with the monitoring instrument, and monitors the mobile point monitoring prism 4.

[0036] According to the scale pointer 11, the swing angle of the mobile point monitoring prism 4 around the vertical support rod 2 is recorded, combined with the relative position relationship between the mobile point monitoring prism 4 and the monitoring point prism 1, and then the monitoring data of the mobile point monitoring prism 4 is integrated and planned, and then the actual monitoring data of the monitoring point prism 1 is obtained, thereby realizing indirect monitoring of the monitoring point.

[0037] In this way, on the one hand, there is no need to manually clean up the debris in the monitoring line of sight, and on the other hand, the monitoring point can be continuously monitored, reducing the difficulty of monitoring and ensuring safety. It meets the requirements of strong practicality, safety and reliability, high efficiency, economy, and simple operation, and realizes safe monitoring of the monitoring point in the presence of obstructions.

[0038] Example 2: This example provides a different auxiliary monitoring mechanism. Different from Example 1, in this example, when actual needs are met, the moving point support shaft may not be provided. In this case, a T-shaped annular groove is provided on the circular dial, and a slider is slidably provided in the T-shaped annular groove. The lower end of the moving point monitoring prism is rotatably mounted on the slider and moves with the slider.

[0039] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0040] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.
