Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying, and specifically relates to a hyperbolic cooling tower construction dimension measuring device. Background Technology

[0002] During the construction of hyperbolic cooling towers, in order to ensure the construction dimensions, a total station and a prism are generally used together to measure the height of the building and the angle and distance of the outer wall relative to the centerline. When construction reaches a certain height, obstacles at higher elevations often obstruct the view, preventing the prism from effectively reflecting the distance measurement signal emitted by the total station, which seriously affects measurement efficiency and project progress.

[0003] Current methods primarily involve mounting the prism at the top of a vertical prism rod. While this allows for the measurement of height data, it cannot simultaneously acquire horizontal position information of the measured point, making it difficult to meet the high-precision requirements of construction. This is because, in the construction of hyperbolic cooling towers, as the height increases, dense obstacles such as internal scaffolding and climbing formwork platforms obstruct the total station's line of sight, making measurements impossible. Traditional methods require separate measurements of angles and distances, which is inefficient and carries high safety risks associated with working at heights.

[0004] Therefore, there is an urgent need to provide a hyperbolic cooling tower construction dimension measuring device that can simultaneously measure height and horizontal data, effectively avoid construction obstacles, and ensure the safety and accuracy of high-altitude measurement operations.

[0020] It should be noted that the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: refer to Figure 1-7 A hyperbolic cooling tower construction dimension measuring device includes a total station 3, a prism rod 1, and a signal reflection device 2.

[0022] The total station 3 is placed at the center of the reference plane of the ground floor of the building to be measured.

[0023] The prism rod 1 is horizontally connected to the internal formwork 10 of the building, and its center vertical line in the length direction coincides with the vertical chord of the telescope on the total station 3, ensuring that the angle between the prism rod and the total station lens is consistent. The prism rod 1 is made of high-strength aluminum alloy with a circular hollow cross-section, and its surface is anodized to improve corrosion resistance and wear resistance.

[0024] The signal reflection device 2 is fixedly connected to the front end of the prism rod 1 by M8 stainless steel bolts. It is used to reflect the distance measurement signal emitted by the total station 3. Anti-loosening gaskets are added at the connection to ensure the reliability of the connection.

[0025] The end of the prism rod 1 is horizontally connected to the guide rail, and the guide rail is vertically connected to the formwork 10 inside the building. The prism rod 1 slides on the guide rail.

[0026] A bubble level tube 4 is fixed in the middle of the prism rod to better adjust the rod to a horizontal position.

[0027] The end of the prism rod 1 is fixedly installed with a tail end fixing head 5 to tighten the guide rail and fix the measuring position of the prism rod 1; the tail end fixing head 5 is made of Q235B carbon steel and the surface is galvanized.

[0028] An extension rod 6 is provided between the prism rod 1 and the tail end fixing head 5. The length can be flexibly adjusted according to actual measurement needs to adapt to the measurement needs of buildings of different sizes and to avoid obstruction by obstacles. The extension rod 6 is made of the same aluminum alloy material as the prism rod 1.

[0029] Both the prism rod 1 and the extension rod 6 are equipped with centimeter and millimeter scale markings. The scale markings are made using a black anodized marking process for rapid reading of measurement data. Both the head of the tail-end fixing head 5 and the head of the extension rod 6 are equipped with M18 threaded connectors 7. The ends of both the prism rod 1 and the extension rod 6 are embedded with M18 threaded sleeves 8. The threaded sleeve 8 of the prism rod 1 is threadedly connected to the threaded connector 7 of the extension rod 6, with the gap at the connection controlled within 0.5mm. The threaded sleeve 8 of the extension rod 6 and the threaded connector 7 of the tail-end fixing head 5 also use the same standard connection. All threaded connections are coated with thread-locking adhesive to ensure a firm connection of all components, improve the stability of the overall structure, and effectively prevent a decrease in measurement accuracy due to loosening.

[0030] The signal reflecting device 2 is composed of a prism mounting base 21, a standard prism connector 22, and a corner reflector prism 23 connected in sequence. The high machining precision of the mating surfaces of each component ensures the accuracy of the measurement data. The prism mounting base 21 and the standard prism connector 22 are fixedly connected by an M12 standard prism connector nut, and the prism mounting base 21 is connected to the prism rod 1.

[0031] The top and side surfaces of the bubble level tube 4 are visible, both using 5mm thick tempered glass windows and equipped with a 3x magnifying glass structure, providing an observation field of view of up to 120°, which is beneficial for observing the horizontal state of the prism rod 1 from multiple angles and ensuring measurement accuracy.

[0032] The tail end fixing head 5 includes a fixing end 9 made of stainless steel. The fixing end 9 is L-shaped or strip-shaped, and all edges and corners are rounded with a chamfer radius of 1mm, which eliminates the risk of sharp edge scratches and improves safety in use.

[0033] During the construction of a hyperbolic cooling tower, the inner formwork 10 and outer formwork 11 of the side walls are first erected. Then, the outer wall of the building is formed by pouring concrete between the inner formwork 10 and the outer formwork 11. Because the diameter of the outer wall of the hyperbolic cooling tower varies, such as... Figure 2 The image shows a cooling tower, whose tower wall diameter typically changes (increases or decreases) after a height of several meters or tens of meters.

[0034] During the measurement, the total station 3 is first placed at the center of the bottom reference plane of the cooling tower. Then, the starting point of the section with the same diameter of the tower wall is found (set as the measurement point). Then, the inner formwork 10 and the outer formwork 11 of the tower wall section are vertically erected at the measurement point. Finally, the end of the prism rod 1 is connected to it.

[0035] In another embodiment, a guide rail is installed on the inner formwork 10 of the building, with the guide rail perpendicular to the bottom reference surface and coinciding with the surface of the inner formwork 10, ensuring that their radii are consistent. Since a single inner formwork 10 is typically 3 meters high, a guide rail can be installed on it, and the end of the prism rod 1 can be slidably connected to the guide rail, allowing it to slide vertically along the guide rail, facilitating accurate measurement of the diameter of this section of the tower wall.

[0036] Then, based on the diameter of the tower wall, it is decided whether to connect an extension rod to ensure that the vertical center line of the length direction of prism rod 1 or prism rod 1 + extension rod 6 coincides with the vertical chord of the telescope on the total station 3. The length of extension rod 6 can be designed according to the actual situation, or multiple extension rods can be designed according to the diameter of the cooling tower wall, and then different extension rods can be selected according to the limited line of sight during on-site measurement.

[0037] During measurement, the corner reflector prism 23 reflects the light signal from the total station 3 back, and the height is then determined based on the speed of light and time. Alternatively, the location of other parts of the cooling tower wall can be determined by directly measuring the distance from the connection point between the signal reflection device 2 and the prism rod 1 to the measuring point at the end of the prism rod 1. A laser rangefinder can also be used to determine the height.

[0038] In addition, a total station and a laser rangefinder can be used together to measure the angle of the cooling tower wall relative to the vertical. This is existing technology and will not be described here.

[0039] Example 2: refer to Figure 8 The measuring device provided in this embodiment is basically the same as that in Embodiment 1, with the main difference being: The fixing end 9 of the tail fixing head 5 in Embodiment 1 has an L-shaped structure, which is suitable for occasions requiring greater load-bearing capacity.

[0040] In this embodiment, the fixing end 9 of the tail-end fixing head 5 is a strip-shaped structure, which focuses more on conductivity and electromagnetic interference resistance, making it particularly suitable for measurement environments requiring electrical connections. The fixing end 9 in this embodiment contacts the guide rail, allowing static electricity or interference signals from the device to be conducted to the ground through the guide rail, forming a shielding and discharge path. This enhances the conductivity and electromagnetic shielding performance of the entire prism rod system, ensuring the accuracy of measurement data and operational safety in complex electromagnetic environments.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made using the utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
