Description

Technical Field

[0001] This utility model relates to the field of elevation measurement equipment, specifically to a construction site elevation measurement device. Background Technology

[0002] During the construction of structures, in order to meet the requirements of construction surveying such as construction positioning and layout, equipment installation and inspection, deformation monitoring, and local control densification, primary network, secondary network, and micro-network control surveys are required. Positioning content mainly includes elevation points, angle lines, and axes. Generally, elevation points are selected from some characteristic points during surveying and are not continuous. During construction, if there is no elevation point at a certain construction location, a level pipe must be used to extend the elevation from a nearby location to the construction point.

[0003] The existing leveling pipe is a transparent flexible tube open or connected at both ends, filled with water or other liquids. Based on the principle of communicating vessels, the liquid levels at both ends are at the same elevation. In use, the two ends of the tube are placed at a known elevation point and the construction point, respectively. Then, the positions of the two ends are adjusted up and down until the liquid level at the construction point is level with the elevation point. At this point, the liquid level at the construction point is the known elevation (the height of the elevation point is known, the difference in height between the liquid level and the elevation point is readable, and the elevation of the construction point can be directly calculated). This construction method utilizes the principle of communicating vessels, ensuring that the liquid levels at both ends of the leveling pipe are consistent. While it can determine the elevation of an unknown construction point relatively accurately, it suffers from difficulties in adjusting the liquid level, is time-consuming to verify, and contains a certain degree of error. The time and error depend on the experience of the personnel. Utility Model Content

[0004] To address the technical problems of large errors and long time consumption in construction site elevation measurement using a level tube, this utility model provides a construction site elevation measuring device that can quickly and synchronously adjust the height of the liquid levels at both ends of the level tube, thereby reducing the error in construction site elevation measurement and improving the efficiency of elevation measurement.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a construction site elevation measurement device, comprising: a measuring liquid container, wherein the measuring liquid container has a storage cavity for holding measuring liquid, and the volume of the storage cavity is adjustable; a first measuring tube, the lower end of the first measuring tube being connected to the measuring liquid container, and the upper section being placed at a known elevation point in the working state; and a second measuring tube, the lower end of the second measuring tube being connected to the measuring liquid container, and the upper section being placed at the construction point to be measured in the working state, wherein the upper end of the second measuring tube is at the same pressure as the upper end of the first measuring tube; wherein, when the volume of the storage cavity is increased, the measuring liquid in the first measuring tube and the second measuring tube can be drawn into the measuring liquid container, and when the volume of the storage cavity is decreased, the measuring liquid in the measuring liquid container can be forced into the first measuring tube and the second measuring tube.

[0007] The construction site elevation measuring device provided by this utility model includes a measuring liquid container, a first measuring tube, and a second measuring tube. The volume of the storage cavity inside the measuring liquid container is adjustable. The lower ends of both the first and second measuring tubes are connected to the measuring liquid container. In the working state, the upper section of the first measuring tube is placed at a known elevation point, and the upper end of the second measuring tube is placed at the construction point to be measured. Furthermore, the upper end of the second measuring tube is at the same pressure as the upper end of the first measuring tube, so that the first measuring tube, the measuring liquid container, and the second measuring tube form a communicating vessel. When measuring elevation, if the volume of the storage cavity is increased, the measuring liquid in the first and second measuring tubes is drawn into the measuring liquid container, thereby simultaneously lowering the liquid level in the first and second measuring tubes. If the volume of the storage cavity is decreased, the measuring liquid in the measuring liquid container is forced into the first and second measuring tubes, thereby simultaneously raising the liquid level in the first and second measuring tubes.

[0008] Therefore, the construction site elevation measuring device provided by this utility model can quickly and synchronously adjust the height of the liquid level at both ends of the horizontal tube without having to adjust the liquid level at both ends of the horizontal tube separately. The liquid level elevation adjustment is convenient and efficient. Moreover, only the liquid level at one end of the horizontal tube needs to be observed, making adjustment convenient and the measurement error small. In other words, this utility model can reduce the error of elevation measurement at the construction site and improve the efficiency of elevation measurement.

[0009] In an optional embodiment of this application, the storage cavity of the measuring liquid container is a cylindrical cavity to facilitate linear adjustment of the storage cavity volume.

[0010] In an optional embodiment of this application, the measuring liquid container has a cylindrical structure to facilitate its processing.

[0011] In an optional embodiment of this application, an adjusting piston is further included, which is adapted to the storage cavity to adjust the volume of the storage cavity by moving the adjusting piston.

[0012] In an optional embodiment of this application, the adjusting piston is movable along the height direction of the storage cavity to facilitate driving the adjusting piston to move.

[0013] In an optional embodiment of this application, a piston drive is further included, which is mounted on the measuring liquid container; the piston drive is throttlely connected to the adjusting piston and movably connected to the measuring liquid container, so as to adjust the height of the adjusting piston in the measuring liquid container by means of the piston drive.

[0014] In an optional embodiment of this application, the piston drive is a screw, the lower end of the piston drive is rotatably connected to the adjusting piston, and the rod of the piston drive is screwed to the measuring liquid container to facilitate precise adjustment of the volume of the storage chamber.

[0015] In an optional embodiment of this application, the upper ends of both the first measuring tube and the second measuring tube are open, so that the first measuring tube and the second measuring tube are in communication with the atmosphere.

[0016] In an optional embodiment of this application, both the first measuring tube and the second measuring tube are transparent flexible tubes to facilitate the arrangement of the first and second measuring tubes and to facilitate the observation of the liquid level inside them.

[0017] In an optional embodiment of this application, the second measuring tube is provided with multiple tubes to facilitate simultaneous measurement of the elevation of multiple construction points to be measured.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The construction site elevation measuring device provided by this utility model includes a measuring liquid container, a first measuring tube, and a second measuring tube. The volume of the storage cavity inside the measuring liquid container is adjustable. The lower ends of both the first and second measuring tubes are connected to the measuring liquid container. In the working state, the upper section of the first measuring tube is placed at a known elevation point, and the upper end of the second measuring tube is placed at the construction point to be measured. Furthermore, the upper end of the second measuring tube is at the same pressure as the upper end of the first measuring tube, so that the first measuring tube, the measuring liquid container, and the second measuring tube form a communicating vessel. When measuring elevation, if the volume of the storage cavity is increased, the volume of the liquid in the first and second measuring tubes will be adjusted. The measuring liquid is drawn into the measuring liquid container, thereby simultaneously lowering the liquid level in the first and second measuring tubes. If the volume of the storage chamber is reduced, the measuring liquid in the measuring liquid container is forced into the first and second measuring tubes, thereby simultaneously raising the liquid level in the first and second measuring tubes. This allows for rapid and synchronous adjustment of the liquid level at both ends of the horizontal tube without the need to adjust the liquid level at each end separately. The liquid level adjustment is convenient and efficient, and only the liquid level at one end of the horizontal tube needs to be observed. The adjustment is convenient, the measurement error is small, and it can reduce the error of elevation measurement on the construction site and improve the efficiency of elevation measurement.

[0030] Example

[0031] Combination Figure 1 This embodiment provides a construction site elevation measurement device, comprising: a measuring liquid container 1, wherein the measuring liquid container 1 is provided with a storage cavity 2 for holding measuring liquid, and the volume of the storage cavity 2 is adjustable; a first measuring tube 3, the lower end of the first measuring tube 3 being connected to the measuring liquid container 1, and the upper section being placed at a known elevation point in the working state; and a second measuring tube 4, the lower end of the second measuring tube 4 being connected to the measuring liquid container 1, and the upper section being placed at the construction point to be measured in the working state, wherein the upper end of the second measuring tube 4 is at the same pressure as the upper end of the first measuring tube 3; wherein, when the volume of the storage cavity 2 is increased, the measuring liquid in the first measuring tube 3 and the second measuring tube 4 can be drawn into the measuring liquid container 1, and when the volume of the storage cavity 2 is decreased, the measuring liquid in the measuring liquid container 1 can be forced into the first measuring tube 3 and the second measuring tube 4.

[0032] In this embodiment, the storage cavity 2 of the measuring liquid container 1 is a cylindrical cavity, so as to facilitate linear adjustment of the volume of the storage cavity 2.

[0033] Accordingly, the measuring liquid container 1 has a cylindrical structure to facilitate its processing.

[0034] Specifically, the volume of the storage chamber 2 of the measuring liquid container 1 can be adjusted by using a flexible material to make the measuring liquid container 1, or by using a piston or other movable partitions to assemble it into a container with a variable volume.

[0035] This embodiment uses a piston-type container, that is, this embodiment also includes an adjusting piston 5, which is adapted to the storage cavity 2 so as to adjust the volume of the storage cavity 2 by moving the adjusting piston 5.

[0036] It is understood that the measuring liquid container 1 can be placed vertically or horizontally, and correspondingly, the adjusting piston 5 can be set vertically or horizontally. For example, the adjusting piston 5 can move along the height direction of the storage cavity 2 to facilitate the movement of the adjusting piston 5.

[0037] In addition, a piston drive 6 is also included, which is mounted on the measuring liquid container 1; the piston drive 6 is drivenly connected to the adjusting piston 5 and movably connected to the measuring liquid container 1, so as to adjust the height of the adjusting piston 5 in the measuring liquid container through the piston drive 6.

[0038] It is understood that the piston drive component 6 can be a damping push rod, an electric push rod, a threaded rod, etc. In this embodiment, to solve the problem of fine adjustment and hovering of the adjusting piston 5, the piston drive component 6 is a screw. The lower end of the piston drive component 6 is rotatably connected to the adjusting piston 5, and the rod part of the piston drive component 6 is screwed to the measuring liquid container 1 to facilitate precise adjustment of the volume of the storage chamber 2.

[0039] To further improve the adjustment accuracy of the liquid level, a rotating rod can be connected to a screw-type piston drive 6 via a reduction gear to reduce the distance the adjusting piston 5 moves when the screw-type piston drive 6 is rotated.

[0040] It should be understood that the upper ends of both the first measuring tube 3 and the second measuring tube 4 are open, so that the first measuring tube 3 and the second measuring tube 4 are in communication with the atmosphere.

[0041] Typically, both the first measuring tube 3 and the second measuring tube 4 are transparent flexible tubes to facilitate their placement and observation of the liquid level. Silicone flexible tubes could also be used.

[0042] Based on this, multiple second measuring tubes 4 are provided to facilitate simultaneous measurement of the elevation of multiple construction points to be measured. It is known that the number of second measuring tubes 4 is determined according to the number of construction points to be measured.

[0043] In summary, the construction site elevation measuring device provided in this embodiment includes a measuring liquid container 1, a first measuring tube 3, and a second measuring tube 4. The volume of the storage chamber 2 inside the measuring liquid container is adjustable. The lower ends of both the first measuring tube 3 and the second measuring tube 4 are connected to the measuring liquid container 1. In the working state, the upper section of the first measuring tube 3 is placed at a known elevation point, and the upper end of the second measuring tube 4 is placed at the construction point to be measured. Furthermore, the upper end of the second measuring tube 4 is at the same pressure as the upper end of the first measuring tube 3, so that the first measuring tube 3, the measuring liquid container 1, and the second measuring tube 4 constitute a communicating vessel.

[0044] When measuring elevation, the measuring liquid (such as water) is poured into the storage chamber 2, and air bubbles are removed. Then, the upper section of the first measuring tube 3 is installed at a known elevation point, and the upper end of the second measuring tube 4 is installed at the corresponding construction point to be measured. Then, the adjusting piston 5 is moved to adjust the liquid level of the first measuring tube 3 and the second measuring tube 4. That is, if the volume of the storage chamber 2 is increased, the measuring liquid in the first measuring tube 3 and the second measuring tube 4 is drawn into the measuring liquid container 1, thereby simultaneously lowering the liquid level of the first measuring tube 3 and the second measuring tube 4. If the volume of the storage chamber 2 is decreased, the measuring liquid in the measuring liquid container 1 is forced into the first measuring tube 3 and the second measuring tube 4, thereby simultaneously raising the liquid level of the first measuring tube 3 and the second measuring tube 4.

[0045] The liquid level in the first measuring tube 3 and the second measuring tube 4 is always at the same elevation. When the liquid level in the first measuring tube 3 is level with the elevation of a known point, the position of the liquid level at the construction point is the known elevation (the elevation of the point is known, the difference between the liquid level and the elevation point is readable, and the elevation of the construction point can be directly calculated).

[0046] In summary, the construction site elevation measuring device provided in this embodiment can quickly and synchronously adjust the height of the liquid level at both ends of the horizontal tube without having to adjust the liquid level at both ends of the horizontal tube separately. The liquid level elevation adjustment is convenient and efficient. Moreover, only the liquid level at one end of the horizontal tube needs to be observed, making adjustment convenient and reducing measurement errors. This can reduce the error in elevation measurement at the construction site and improve the efficiency of elevation measurement.

[0047] It should be understood that the construction site elevation measuring device provided in this embodiment is applicable to various usage environments and is not limited to building construction, such as replacing a spirit level for the installation of large equipment.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
