DETAILED DESCRIPTION

[0023] 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:

[0025] refer to Figures 1 to 4 The utility model provides a monitoring point protection device (hereinafter referred to as the protection device), including a mounting base 1 at the bottom, on which a protective tube 2 is arranged, and the interior of the protective tube 2 constitutes a protective space for protecting the monitoring point 4. At least two concentric annular tracks 12 are arranged at intervals along the center of the upper end of the mounting base 1. The protective tube 2 includes a plurality of arc-shaped guard plates 21 adapted to the annular tracks 12. An arc-shaped guard plate 21 adapted to the annular tracks 12 is slidably arranged on each annular track 12, and the total curvature of all the arc-shaped guard plates 21 is 360 degrees. The upper end of the protective tube 2 is also covered with a protective cover 3.

[0026] Specifically, during actual construction, Figure 4 As shown, the monitoring point 4 is generally set on a concrete base 5. In this embodiment, as shown in FIG. Figure 1 , 2 As shown, preferably, a mounting through hole 11 arranged concentrically with the annular track 12 is provided on the mounting base 1 , and the mounting through hole 11 is sleeved on the concrete base 5 from top to bottom, and the monitoring point 4 is set in the protective tube 2 .

[0027] In this embodiment, the circular track 12 includes three tracks, namely, a first circular track 121, a second circular track 122 and a third circular track 123 from the inside to the outside, and the arc guard plate 21 includes a first arc guard plate 211, a second arc guard plate 212 and a third arc guard plate 213 which are respectively slidably arranged on the first circular track 121, the second circular track 122 and the third circular track 123, and the curvature of the three arc guard plates 21 is 120 degrees.

[0028] Preferably, in this embodiment, a linkage closed structure is arranged between adjacent arc-shaped guard plates 21, and the linkage closed structure includes a first baffle 22 and a second baffle 23 which are respectively arranged on the relatively inner arc-shaped guard plate 21 and the relatively outer arc-shaped guard plate 21, and the first baffle 22 and the second baffle 23 extend radially toward each other, and in the circumferential direction, the first baffle 22 is at the rear end of the relatively inner arc-shaped guard plate 21, and the second baffle 23 is at the front end of the relatively outer arc-shaped guard plate 21.

[0029] Specifically, in this embodiment, if Figure 1 , 2 As shown, the intervals between the first annular track 121, the second annular track 122 and the third annular track 123 are the same. A first baffle 22 is provided at the inner end of the first arc-shaped guard plate 211 and the second arc-shaped guard plate 212, and a second baffle 23 is provided at the outer end of the second arc-shaped guard plate 212 and the third arc-shaped guard plate 213. The first baffle 22 and the corresponding second baffle 23 are matched in the circumferential direction.

[0030] Specifically, Figure 1 , 2 As shown, a first baffle plate 22 is provided at one end of the inner side of the first arc-shaped guard plate 211, and the first baffle plate 22 extends radially toward the second arc-shaped guard plate 212 along the first annular track 121, and the radial length of the first baffle plate 22 is the same as the interval between the first annular track 121 and the second annular track 122.

[0031] A second baffle plate 23 is provided at an outer end of the second arc-shaped guard plate 212 . The second baffle plate 23 is an L-shaped plate. The inner side of the L-shaped plate extends radially inward, and the inner end of the L-shaped plate in the radial direction extends to the outer side surface of the first arc-shaped guard plate 211 .

[0032] Similarly, the first baffle plate 22 at the inner end of the second arc-shaped guard plate 212 is arranged in the same manner as the first baffle plate 22 at the inner end of the first arc-shaped guard plate 211, and the second baffle plate 23 at the outer end of the third arc-shaped guard plate 213 is arranged in the same manner as the second baffle plate 23 at the outer end of the second arc-shaped guard plate 212, which will not be described in detail. In this way, by utilizing the linkage closed structure, the innermost first arc-shaped guard plate 211 can be rotated to drive the second arc-shaped guard plate 212 to rotate, thereby forming a closed cylindrical protective tube 2, enclosing a closed protective space, and enclosing the monitoring point 4 inside the protective tube 2.

[0033] Preferably, in this embodiment, in the circumferential direction, a third baffle plate 24 is provided at the front end of the innermost arc-shaped guard plate 21 , and the third baffle plate 24 extends radially outward to the outermost annular track 12 .

[0034] Specifically, Figure 1 , 2 As shown, the third baffle 24 is arranged at one end of the outer side of the first arc-shaped guard plate 211, and the third baffle 24 extends radially to the outer side of the third annular track 123, and a fourth baffle 25 is arranged at one end of the inner side of the third arc-shaped guard plate 213. In this way, when the protective tube 2 is closed, the third baffle 24 can cooperate with the fourth baffle 25 to block, and the third baffle 24 can close the interval between the first arc-shaped guard plate 211 and the third arc-shaped guard plate 213, forming a closed protective space, thereby improving the protective capability.

[0035] Preferably, in this embodiment, the annular track 12 is an annular groove provided on the mounting base 1. Specifically, the first annular track 121, the second annular track 122 and the third annular track 123 are all annular grooves, and the lower ends of the first arc-shaped guard plate 211, the second arc-shaped guard plate 212 and the third arc-shaped guard plate 213 respectively penetrate and slide in the corresponding annular grooves. Of course, in other embodiments, the annular track 12 can also be a protruding annular guide rail provided on the mounting base 1, and the lower ends of the first arc-shaped guard plate 211, the second arc-shaped guard plate 212 and the third arc-shaped guard plate 213 are respectively provided with notches adapted to the corresponding annular guide rails, so as to achieve sliding installation.

[0036] Preferably, in this embodiment, the protective cover 3 is hingedly connected to the outermost arc-shaped guard plate 21. Figure 3 As shown, a hinge shaft 31 is provided on one side of the protective cover 3, and a hinge seat (not shown in the figure) adapted to the hinge shaft 31 is provided on the outer side of the third arc-shaped guard plate 213, and the hinge shaft 31 is rotatably installed in the hinge seat, so that the protective cover 3 can be opened and closed by flipping, which is easy to operate.

[0037] At the same time, a fixing buckle 32 is also provided at the end of the protective cover 3 facing away from the hinge shaft 31, and a snap-fitting notch (not shown in the figure) adapted to the fixing buckle 32 is provided on the outer periphery of the second arc-shaped guard plate 212. In this way, when each arc-shaped guard plate 21 is closed to form a cylindrical protective tube 2, the protective cover 3 can be fixed by cooperating with the fixing buckle 32 and the snap-fitting notch to prevent the protective cover 3 from being opened, thereby improving the protection effect.

[0038] The working process of the present application is as follows: when it is necessary to protect the monitoring point 4, the mounting base 1 is mounted on the monitoring point 4 through the mounting through hole 11, and then the third baffle 24 is dragged to drive the first arc-shaped guard plate 211 to rotate, and the first arc-shaped guard plate 211 drives the second arc-shaped guard plate 212 to rotate through the corresponding first baffle 22 and the second baffle 23. When the third baffle 24 and the fourth baffle 25 are blocked, the first baffle 22 on the second arc-shaped guard plate 212 and the second baffle 23 on the third arc-shaped guard plate 213 are blocked, and at this time a closed, cylindrical protective tube 2 is formed.

[0039] The protective cover 3 is put on and fixed on the protective tube 2 by means of the fixing buckle 32 to form a closed protective space to protect the monitoring point 4 .

[0040] When the monitoring point 4 does not need to be protected temporarily, the third baffle 24 can be dragged in the reverse direction to open the protective tube 2, so that the monitoring point 4 is exposed and can continue to be monitored. At the same time, the protective device is designed separately from the mounting base 1, the protective tube 2 and the protective cover 3. After the protection of the monitoring point is completed, the protective device can be taken away to other areas and recycled to continue to protect other monitoring points 4. The protective tube 2 is designed in petals, which is easy to carry and transport and quick to operate.

[0041] In summary, the protective device of the utility model can form a closed protective space using the protective tube 2 and the protective cover 3 to prevent the monitoring point 4 from being damaged during the construction process. The protective tube 2 is composed of a plurality of arc-shaped protective plates 21, and the sum of the curvatures of the plurality of arc-shaped protective plates 21 is 360 degrees. When protection is needed, the arc-shaped protective tube 2 is formed by rotating the arc-shaped protective plates 21 to close. On the one hand, it is convenient to install the protective tube 2 on the monitoring point 4, and on the other hand, it is convenient to enclose a closed protective space. At the same time, when protection is not needed, the protective tube 2 can be opened to perform monitoring tasks, thereby improving practicality.

[0042] Example 2: This example provides a different protective device. Different from Example 1, in this example, the mounting base can be designed as an integral unit with the concrete base below the monitoring point. When the monitoring point is arranged and constructed, the corresponding concrete base is first processed, and then three sets of circular tracks are opened on the concrete base. When protection is needed, the arc-shaped guard plate of the protective tube only needs to be installed on the corresponding circular track.

[0043] Example 3: This example provides a different protective device. Different from Example 1, in this example, the number of circular tracks can be set according to actual needs, such as setting two, four or five tracks. In this case, it is necessary to ensure that the number of arc guard plates is the same as the number of circular tracks, and corresponding arc guard plates are set on each circular track. At the same time, the total curvature of each arc guard plate is 360 degrees, which can be closed to form a closed cylindrical protective tube.

[0044] 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.

[0045] 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.

[0046] 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.
