Description

Technical Field

[0001] This utility model relates to the technical field of settlement detection, specifically a settlement detection device for power transmission towers. Background Technology

[0002] Transmission towers, also known as power line towers or electric power towers, are essential structures used to support and erect transmission lines. Their primary function is to support conductors, lightning protection wires, and other accessories, and to ensure that the conductors maintain the prescribed safe distances from the ground and other facilities, thereby guaranteeing the safe operation of the transmission lines. Transmission towers are typically made of steel, possessing high strength and stability, and capable of bearing the weight of the conductors. However, wind loads and natural disasters such as earthquakes can alter the bearing capacity of the foundation, causing the tower foundation to loosen or settle, thus threatening the tower's stability. Therefore, detection devices are needed to monitor the settlement of transmission towers in real time.

[0003] Existing settlement detection devices generally use hydrostatic levels, which are fixedly installed at the four corners of the tower or other key locations. Their working principle is based on the principle of communicating vessels in fluid statics, that is, in connected liquid containers, the liquid level will remain consistent. Multiple hydrostatic levels are connected in parallel through connecting pipes. When connecting the connecting pipes to the liquid storage tanks of the hydrostatic levels, auxiliary tools are needed to lock them to prevent loosening and leakage. This makes the installation process cumbersome for operators, and makes disassembly inconvenient, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a power transmission tower settlement detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A power transmission tower settlement detection device is installed around the power transmission tower and includes multiple static levels, with adjacent static levels connected by a connecting pipe inside the tower.

[0007] The hydrostatic level is symmetrically provided with connecting seats, and the connecting seats are equidistantly distributed with grooves along the circumference.

[0008] The connecting pipe is provided with connectors at both ends, and the connecting seat is inserted into the connector. The elastic snap-fit ​​members arranged equidistantly along the circumference inside the connector can be inserted into the groove.

[0009] A locking element, disposed on the connecting pipe, is capable of locking the elastic snap-fit ​​element inserted into the groove.

[0010] As described above, the power transmission tower settlement detection device includes a protrusion, and an insertion groove is formed on the inner wall of the connector. One end of the protrusion is slidably disposed in the insertion groove, and the other end can be inserted into the groove to engage with the connecting seat.

[0011] It also includes a spring, which is disposed in the insertion groove, with one end of the spring abutting against the inner end of the insertion groove and the other end abutting against the protrusion.

[0012] As described above, in the power transmission tower settlement detection device, the locking member can be controlled by a pushing component disposed on the connecting pipe to move and insert into the protrusion when the protrusion is inserted into the groove.

[0013] The power transmission tower settlement detection device described above: the pushing component includes a knob arranged axially along the connecting pipe, the connecting pipe having an external thread that is threadedly connected to the knob, and the knob being rotatably connected to the locking member.

[0014] As described above, the power transmission tower settlement detection device includes a movable sleeve that is slidably arranged along the axial direction of the joint. The movable sleeve has through holes that can be inserted into the protrusions at equal intervals along the circumference, and the movable sleeve is rotatably connected to the knob.

[0015] As described above, the power transmission tower settlement detection device has at least one set of sliding grooves formed in the cylindrical groove of the connector, and the movable sleeve is provided with a slider that slides in cooperation with the sliding grooves.

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

[0017] By controlling the connection of both ends of the connecting pipe to the connecting seat, when the connector is inserted into the connecting seat, the end of the connecting seat squeezes the elastic snap-fit, causing the elastic snap-fit ​​to store elastic potential energy under pressure. When the connecting seat is fully inserted into the connector, the elastic snap-fit ​​loses the squeezing and can insert into the groove under the elastic force. The locking device locks the position of the elastic snap-fit, so that the two ends of the connecting pipe are sealed to the connecting seat, while effectively preventing fluid leakage, ensuring the sealing and safety of the pipeline system, and ensuring the accuracy of the hydrostatic level.

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-6 In this embodiment of the utility model, a power transmission tower settlement detection device is set around the power transmission tower and includes multiple static level instruments 1, and two adjacent static level instruments 1 are connected through the inside of a connecting pipe 8.

[0029] The static level 1 is symmetrically provided with a connecting seat 2, and the connecting seat 2 is provided with grooves 201 evenly distributed along the circumference;

[0030] The connecting pipe 8 is provided with connectors 3 at both ends, and the connecting seat 2 is inserted into the connector 3. The elastic snap-fit ​​members arranged equidistantly along the circumference inside the connector 3 can be inserted into the groove 201.

[0031] A locking element is provided on the connecting pipe 8, which can lock the elastic snap-fit ​​element inserted into the groove 201.

[0032] Preferably, a sealing ring is provided inside the connector 2. After the connector 3 is inserted into the connector 2, the sealing ring can prevent leakage at the connection between the connector 3 and the connector 2.

[0033] It should be noted that multiple static level instruments 1 are typically installed in the settlement monitoring of transmission towers, distributed around the perimeter of the tower. The static level instrument system usually consists of multiple monitoring points connected by a connecting pipe 8, forming a complete monitoring network. Each monitoring point is equipped with a static level instrument 1 to measure changes in relative elevation, thereby achieving accurate monitoring of the transmission tower settlement. The specific detection method of the static level instrument 1 is existing technology and will not be further explained in this application.

[0034] In detail, when two adjacent hydrostatic levels 1 are connected, the two ends of the connecting pipe 8 are connected to the connecting seat 2 respectively. When the connector 3 is inserted into the connecting seat 2, the end of the connecting seat 2 squeezes the elastic snap-fit, causing the elastic snap-fit ​​to be compressed and store elastic potential energy. When the connecting seat 2 is fully inserted into the connector 3, the elastic snap-fit ​​loses the compression and can be inserted into the groove 201 under the elastic force. The locking device locks the position of the elastic snap-fit, so that the two ends of the connecting pipe 8 are sealed to the connecting seat 2 respectively, which can effectively prevent fluid leakage, ensure the sealing and safety of the pipeline system, and ensure the accuracy of the hydrostatic level 1.

[0035] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The elastic snap-fit ​​component includes a protrusion 5, and an insertion groove 301 is formed on the inner wall of the connector 3. One end of the protrusion 5 is slidably disposed in the insertion groove 301, and the other end can be inserted into the groove 201 to snap-fit ​​with the connecting seat 2.

[0036] It also includes a spring 4, which is disposed in the insertion groove 301. One end of the spring 4 abuts against the inner end of the insertion groove 301, and the other end abuts against the protrusion 5.

[0037] Preferably, the two ends of the protrusion 5 are formed with inclined surfaces, so that when the protrusion 5 is squeezed by the end of the connector 2, the protrusion 5 is subjected to an inclined force and moves toward the insertion groove 301, so as to make way for the connector 2, so that the connector 3 and the connector 2 can be smoothly inserted.

[0038] In the initial state, the spring 4 is in a compressed state. When the protrusion 5 is squeezed by the connecting seat 2, the protrusion 5 slides towards the insertion groove 301, compressing the spring 4 again until the connector 3 drives the protrusion 5 to move until the protrusion 5 and the groove 201 are aligned. At this time, the protrusion 5 loses the squeezing force and is stuck into the groove 201 by the elastic force of the spring 4. At this time, the insertion between the connector 3 and the connecting seat 2 is not locked. By controlling the locking element to be inserted into the protrusion 5, the separation of the protrusion 5 and the groove 201 can be avoided, thereby realizing the tight insertion of the connecting seat 2 and the connector 3.

[0039] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The locking member can be moved and inserted into the protrusion 5 by a pushing component provided on the connecting pipe 8 when the protrusion 5 is inserted into the groove 201.

[0040] The pushing component includes a knob 7 arranged axially along the connecting pipe 8, the connecting pipe 8 having an external thread that is threadedly connected to the knob 7, and the knob 7 being rotatably connected to the locking member.

[0041] The locking component includes a movable sleeve 6 that is slidably disposed along the axial direction of the connector 3. The movable sleeve 6 has through holes 501 that can be inserted into the protrusion 5 at equal intervals along the circumference, and the movable sleeve 6 is rotatably connected to the knob 7.

[0042] Preferably, at least one set of sliding grooves 302 are formed in the cylindrical groove of the connector 3, and a slider 601 that slides with the sliding grooves 302 is provided on the movable sleeve 6. Under the restriction of the sliding grooves 302 and the slider 601, it is possible to prevent the movable sleeve 6 from rotating synchronously when the knob 7 is turned.

[0043] After the aforementioned protrusion 5 is inserted into the groove 201, the control knob 7 is rotated relative to the connector 3. Due to the threaded connection between the knob 7 and the connector 3, when the knob 7 rotates relative to the connector 3, the knob 7 makes a linear motion along the axis of the connector 3. When the knob 7 moves relative to the connector 3, it can squeeze the movable sleeve 6. Under the restriction of the slider 601 and the slide groove 302, the locking rod 602 on the movable sleeve 6 can always be aligned with the through hole 501. Under the squeezing of the knob 7, the locking rod 602 is inserted into the through hole 501 to lock the position of the protrusion 5, so as to realize the tight connection between the connector 3 and the connecting seat 2 and ensure the accuracy of the hydrostatic level 1.

[0044] Preferably, at least one extrusion plate 701 is distributed along the circumference of the knob 7, and the end of the extrusion plate 701 away from the knob 7 is rotatably connected to the movable sleeve 6.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
