Technical Field
[0001] This utility model relates to the field of settlement observation technology, specifically a new type of settlement observation point device for a booster station. Background Technology
[0002] A step-up substation is an important facility in a power system, mainly used to raise the voltage from low to high. Step-up substations may experience settlement due to factors such as unstable foundation, substandard building structure design or construction quality, and poor soil compressibility. Settlement monitoring is to ensure the safe and stable operation of buildings and equipment.
[0003] Most of the existing settlement observation points at substations have protruding walls on the outside. Inadequate protection measures inevitably lead to collisions with the settlement observation points, which can affect the accuracy of settlement observation data. Moreover, the protruding parts on the outside of the settlement observation points pose a risk of tripping and falling to maintenance personnel, affecting their personal safety. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of settlement observation point device for substations, in order to solve the problem mentioned in the background art that most of the existing settlement observation point devices for substations are in the state of having protruding walls on the outside. Inadequate protection measures inevitably lead to collisions with the settlement observation points, which will affect the accuracy of settlement observation data. Moreover, the protruding parts on the outside of the settlement observation points pose a risk of tripping and falling to maintenance personnel, affecting personal safety.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel settlement observation point device for a booster station, comprising a pre-embedded box and a settlement observation component, wherein the settlement observation component is installed in the pre-embedded box, the pre-embedded box comprising an inner box and an outer box, the outer box being connected to the inner box, the settlement observation component comprising a first rod, a second rod, and a measuring head, the first rod being inserted into the inner box, the second rod being rotatably connected to the first rod, and the second rod being foldable within the inner area of the outer box.
[0006] Preferably, the outer surface of the inner box has a groove in the direction perpendicular to the direction in which the settlement observation piece is inserted into the pre-embedded box.
[0007] Preferably, a fixing member is provided inside the outer box, and the second rod is snapped into place with the fixing member on its periphery when the rod is folded.
[0008] Preferably, an installation kit is fitted on the outer side of the first rod near the second rod, and the end of the kit away from the second rod is fixedly connected to the periphery of the first rod by a bottom ring. The end of the kit away from the second rod is installed inside the outer box by an installation plate.
[0009] Preferably, the inner diameter of the kit is larger than the outer diameter of the first rod. A movable sleeve is provided at the gap between the kit and the first rod. The movable sleeve is fitted over the outside of the first rod. The outer diameters of the first rod and the second rod are the same. When the second rod is parallel to the first rod, the distance between the inner surface of the movable sleeve and the surface of the first rod is small and just enough to allow the movable sleeve to slide from only outside the first rod to outside both the first rod and the second rod.
[0010] Preferably, the second rod body is provided with a sleeve limiting member on its periphery to prevent the movement of the movable sleeve.
[0011] Preferably, a positioning frame is provided at the outer edge of the outer box body, and a pre-embedded box cover is installed on the positioning frame. The pre-embedded box cover includes a box cover frame and a box cover plate. The box cover frame is correspondingly installed on the positioning frame, and the box cover plate is hinged to the opening of the box cover frame.
[0012] Preferably, the second rod can be folded upwards into the inner area of the outer box. The pre-embedded box cover also includes an inner frame and a support member. The inner frame is provided on the side of the box cover frame near the outer box. The support member is installed on the bottom surface of the opening of the inner frame. The upper part of the support member is an arc surface. The size and height of the arc surface match the outer diameter of the second rod in the open state.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the connection method between the second rod and the first rod, and the segmented arrangement of the second rod and the first rod, allows the second rod to be folded to a position not exceeding the wall surface. Only when settlement observation is required will the second rod be rotated to a state parallel to the first rod. Compared with the method of pre-embedded L-shaped settlement observation nails, this can avoid the situation where the protruding part of the wall is easily bumped during the non-observation period. The settlement observation piece is not easily bumped, so the observation data is not easily affected, and the data results are more accurate; at the same time, it reduces the risk of pedestrians tripping at the protruding part, protecting personal safety.
[0015] 2. By setting up a movable sleeve, when the movable sleeve is fitted onto the first rod and the second rod, it can ensure that the direction of the second rod is stably parallel to the first rod during observation, thereby achieving the consistency of the expected position of the measuring head when pre-embedding the box. This also ensures that the position height of the measuring head is the same during each settlement observation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] One embodiment provided by this utility model: as follows Figure 1 As shown, a novel settlement observation point device for a booster station includes a pre-embedded box 1, a settlement observation component 2, and a pre-embedded box cover 3.
[0027] like Figure 1 , Figure 2 and Figure 3As shown, during construction, the substation embeds the pre-embedded box 1 at the observation point location inside the wall. It consists of two parts: an inner box 11 and an outer box 12. The outer box 12 is flush with the wall surface. The outer surface of the inner box 11 has a groove 111 on its outer surface in the direction perpendicular to the direction in which the settlement observation piece 2 is inserted into the pre-embedded box 1. The groove 111 increases the stability of the pre-embedded box 1.
[0028] like Figure 4 and Figure 5 As shown, the settlement observation element 2 is installed inside the pre-embedded box 1. The settlement observation element 2 includes a first rod 21, a second rod 22, a measuring head 23, a kit 24, and a movable sleeve 25.
[0029] The outer box 12 is connected to the inner box 11. The first rod 21 is inserted into the inner box 11, and the second rod 22 is rotatably connected to the first rod 21. The second rod 22 can be folded upwards inside the outer box 12. The measuring head 23 is located at the end of the second rod 22 away from the first rod 21. The segmented arrangement of the second rod 22 and the first rod 21 allows the second rod 22 to be folded without exceeding the wall surface. Only when settlement observation is required will the second rod 22 be rotated to a state parallel to the first rod 21. Compared with the method of pre-embedded L-shaped settlement observation nails, this can avoid the situation where the protruding part of the wall is easily bumped during the non-observation period. The settlement observation piece is not easily bumped, so the observation data is not easily affected, and the data results are more accurate. At the same time, it reduces the risk of pedestrians tripping at the protruding position and protects personal safety.
[0030] A fixing member 122 is provided inside the outer box 12. When the second rod 22 is folded, its periphery is engaged with the fixing member 122. The fixing member 122 can limit the second rod 22 in the folded state, so that when not under observation, the second rod 22 inside the outer box 12 is not easy to rotate downward and fall off.
[0031] like Figure 6 and Figure 7 As shown, an installation kit 24 is fitted onto the outer side of the first rod 21 near the second rod 22. The end of the kit 24 away from the second rod 22 is fixedly connected to the periphery of the first rod 21 via a bottom ring 241. The end of the kit 24 away from the second rod 22 is installed inside the outer box 12 via an installation plate 242. Because the kit 24 is fixedly connected to the first rod 21, and the installation plate 242 is installed in the outer box 12, the connection between the settlement observation component 2 and the pre-embedded box 1 is strengthened, resulting in more accurate observation data.
[0032] When installing the settlement observation device 2 into the pre-embedded box 1, first insert the end of the first rod 21 into the observation device connection hole 112 of the inner box 11. The outer diameter of the combination of the first rod 21 and the kit 24 is adapted to the inner diameter of the observation device connection hole 112 of the inner box 11. The restriction of the first rod 21 by the observation device connection hole 112 of the inner box 11 can make the settlement observation device 2 horizontally stable and less likely to affect the settlement observation data due to shaking. When the first rod 21 and the kit 24 are fully inserted into the observation device connection hole 112 of the inner box 11, the mounting plate 242 of the kit 24 corresponds exactly to the inner surface of the outer box 12. Fix the mounting plate 242 to the outer box 12 with screws to complete the installation of the settlement observation device 2.
[0033] like Figure 8 As shown, the embedded cover 3 is installed on the surface of the embedded box body 1. A positioning frame 121 is provided at the outer edge of the outer box body 12. The embedded cover 3 includes a cover frame 31 and a cover plate 32. The cover frame 31 is correspondingly installed on the positioning frame 121, and the cover plate 32 is hinged to the opening of the cover frame 31. The embedded cover 3 protects the settlement observation element 2 installed inside the outer box body 12, effectively reducing the possibility of bumping the settlement observation element 2 or dust entering the outer box body 12. When settlement observation is required, the cover plate 32 is opened, and closed after use. In addition, the cover plate 32 can also be locked to restrict the personnel using the device.
[0034] The inner diameter of the kit 24 is larger than the outer diameter of the first rod 21. A movable sleeve 25 is provided in the gap between the kit 24 and the first rod 21. The movable sleeve 25 is fitted over the first rod 21. The outer diameters of the first rod 21 and the second rod 22 are the same. The hinged connection between the first rod 21 and the second rod 22 is smaller than their outer diameters. When the second rod 22 is parallel to the first rod 21, the two rods are coaxial. At this time, the distance between the inner surface of the movable sleeve 25 and the surface of the first rod 21 is small, just enough to allow the movable sleeve 25 to slide from only outside the first rod 21 to outside both the first rod 21 and the second rod 22. A sleeve limiting member 221 is provided on the periphery of the second rod 22 to prevent the movable sleeve 25 from moving excessively. The sleeve limiting member 221 serves as a warning to prevent the movable sleeve 25 from moving excessively. When the movable sleeve 25 is fitted onto the first rod 21 and the second rod 22, it can ensure that the direction of the second rod 22 is stable and parallel to the first rod 21 during observation, thereby achieving the same position of the measuring head 23 as expected when the pre-embedded box 1 is embedded. This also ensures that the position height of the measuring head 23 is the same during each settlement observation.
[0035] The pre-embedded cover 3 also includes an inner frame 33 and a support member 34. The inner frame 33 is set on the side of the cover frame 31 near the outer box body 12. The support member 34 is installed on the bottom surface of the opening of the inner frame 33. The upper part of the support member 34 is an arc surface, and the size and height of the arc surface match the outer diameter of the second rod 22 in the open state. The support member 34 can support and limit the second rod 22 after it is rotated downward during the settlement observation period. The support position of the support member 34 further increases the horizontal stability of the second rod 22 and reduces the deformation caused by the gravity of the extended part of the second rod 22. Therefore, it can also improve the stability of the position of the measuring head 23, thereby ensuring the accuracy of the observation data.
[0036] When conducting settlement observation, first open the cover plate 32, remove the folded second rod 22 from the fixing member 122, and rotate the second rod 22 downwards so that it falls onto the support member 34. At this time, the second rod 22 is parallel to the first rod 21. Move the movable sleeve 25 so that it partially fits around the second rod 22. Then, the settlement observation operation can be carried out directly. The highest point of the measuring head 23 is the observation point. The operation steps required for each observation are simple, the observation position will not be frequently bumped due to the protrusion, and the accuracy of the settlement observation data will not be affected.
[0037] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics in the solutions has not been described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
