Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant reactor building construction technology, specifically to a portable device for transmitting measurement and control networks inside and outside the reactor building. Background Technology

[0002] Currently, in the construction sequence of reactor buildings for domestic nuclear power projects, the hoisting of steel structures and steel linings is faster than the construction of internal civil structures. Due to the obstruction of the steel lining, it is difficult for the internal structure to connect with external secondary network points. Therefore, the current method for establishing a measurement control network for the internal structure is to transfer planar coordinates by using metal sleeves and vertical alignment of micro-network points on the lower plate.

[0003] However, the following drawbacks exist in the vertical transfer of micro-grid points: Since the height difference between each floor slab is usually several meters, vertical alignment of micro-grid points must rely on a zenith instrument. Each micro-grid point requires a zenith instrument for alignment, but the surrounding environment of the micro-grid points is narrow and dark, making alignment difficult. If the micro-grid points are not properly protected, they are easily damaged or deformed. Furthermore, errors are prone to accumulate during the transfer of micro-grid points layer by layer. In addition, this method requires the multiple setup of prisms and instruments during control network measurement, which requires the cooperation of many people to complete. The operation is complex and very time-consuming and labor-intensive. Summary of the Invention

[0004] This invention aims to solve the technical problems of the traditional measurement and control network construction method for the internal structure of reactor buildings being complex and time-consuming, and the difficulty in hierarchical deployment of external secondary control networks into the reactor building after the steel lining of the reactor building is hoisted. The purpose is to provide a portable measurement and control network transmission device for reactor buildings, which can directly mount instruments and prisms to connect measurement and control points inside and outside the reactor building. It eliminates the need to use the lower layer of micro-network points in the internal structure as a reference for transmission, ensuring measurement quality and accuracy while significantly improving work efficiency. Moreover, the device has a simple structure and is easy to install and carry.

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

[0006] A portable measurement and control network transmission device for inside and outside a reactor building, comprising: Base, used to mount measuring instruments; The connector, located at the center of the base, is used to connect to the total station base; Two support legs are located below the base; Fasteners, located on the outriggers, are used to clamp the steel-lined cylinder sidewalls between the two outriggers.

[0007] Furthermore, the connector uses threaded connections.

[0008] Furthermore, the connecting thread is welded to the center of the base.

[0009] Furthermore, the base is a disc, and the connector is concentric with and perpendicular to the disc.

[0010] Furthermore, the support legs are vertically welded to the bottom of the base.

[0011] Furthermore, the distance between the two sets of legs is 10-15 cm, the length of the legs is 20-25 cm, and the width of the legs is 5-8 cm.

[0012] Furthermore, each outrigger is equipped with two sets of fasteners.

[0013] Furthermore, the spacing between the two sets of fasteners is 10-15 cm.

[0014] Furthermore, the fasteners include flange bolts and nuts, the flange bolts being connected to the through holes of the outriggers and being fastened by the nuts.

[0015] Furthermore, the transfer device is made of lightweight, high-strength alloy stainless steel.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects.

[0017] 1. The device of this utility model is equivalent to directly mounting the measuring instrument on the top of the steel-lined cylinder. The installation position is high and the field of view is wide, which has the advantage of field of view. Almost all measurement reference points can be observed. The instrument and prism can be directly placed to connect to the secondary network points outside the plant. The stable secondary network reference points are used as the reference for planar transfer. Compared with the traditional measurement and control network inside the reactor building, which repeatedly sets up the ground plane instrument and prism device during the measurement process, and finds the viewing hole and coordinates the upper and lower layers to perform micro-network point alignment before each measurement, and uses the lower layer micro-network points for transfer measurement, the device of this utility model can avoid the low efficiency and low accuracy caused by the repeated instrument setting, avoid the manpower consumption caused by finding the viewing hole and alignment, and effectively avoid the problem that the bottom micro-network points may be damaged, deformed or blocked, resulting in unreliable micro-network point accuracy. While ensuring measurement quality, the work efficiency is greatly improved.

[0018] 2. The device of this utility model is clipped to the top of the side wall of the steel-lined cylinder. During measurement, the observation is made from the top down towards the internal structure, so it can bypass the enclosure of the steel-lined cylinder and solve the problem that the enclosure of the steel-lined cylinder prevents the measurement from being viewed.

[0019] 3. This utility model utilizes a transfer device that can accommodate instruments and prisms to change the traditional method of establishing a measurement and control network within the internal structure of a reactor building. This device has a good field of view, and the layout and measurement of control points are relatively flexible, greatly improving the convenience, speed, and accuracy of establishing a measurement and control network within the reactor building. It also effectively reduces the input of manpower and material resources, and the device is simple to install and easy to carry. Attached Figure Description

[0028] Example

[0029] This embodiment provides a portable device for transmitting measurement and control networks inside and outside a reactor building, such as... Figures 1-4 As shown, the transfer device is made of lightweight, high-strength alloy stainless steel and includes: Base 1 is used to mount measuring instruments (such as related instruments and prisms); specifically, base 1 is a stainless steel disc. The connector is vertically welded to the center of base 1 to connect to the total station base and ensure concentricity; Two support legs 3 are vertically welded to the bottom of the base 1. The distance between the two sets of support legs 3 is 10-15 cm. The length of the support legs 3 is 20-25 cm and the width of the support legs 3 is 5-8 cm. Specifically, the support legs 3 are made of steel plates. Fasteners are provided on the support legs 3 to clamp the side wall of the steel-lined cylinder 6 within the two support legs 3. Each support leg 3 is provided with two sets of fasteners, which are arranged vertically and vertically with a spacing of 10-15 cm between them. Specifically, the fasteners include flange bolts 4 and nuts 5. The flange bolts 4 are connected to the support legs 3 through holes and are fastened by nuts 5.

[0030] The installation and usage method of the transfer device of this utility model is as follows: (1) Before hoisting the steel-lined cylinder 6, two or more locations (depending on the site conditions) need to be found on the upper part of the side wall of the steel-lined cylinder 6 to install detachable steel stairs and standing platforms. The platform is about 1.2 meters above the upper part of the steel lining. The platform is to provide operating space for surveyors. (2) After the steel lining is hoisted and before the control network is measured, install the device at the selected location (the installation location of this utility model device needs to be combined with the distribution of secondary network points on site, and the device should be able to see each other). (3) Installation is very simple and convenient. The two legs 3 of this utility model device are clamped on the upper side wall of the steel lining cylinder 6. The flange bolts 4 are tightened inside and outside with a wrench to make them tightly connected with the steel lining cylinder 6. After it is stable, the installation can be completed. Then instruments and prisms can be placed on the device to connect the internal and external measurement and control points of the reactor building. The installation process is very convenient and the efficiency is greatly improved.

[0031] In existing technologies, normal micromeasuring networks with internal structures require the installation of measuring instruments at the viewing holes of each reference point on both the upper and lower layers. A baseplate is used for alignment to achieve data transfer between layers. However, with this device, the measuring instruments are directly mounted on the top of the steel-lined cylinder 6. The higher installation position provides a wider field of view, offering a significant advantage. Almost all measurement reference points can be observed. Instruments and prisms can be directly installed to connect to secondary network points outside the plant. Stable secondary network reference points are used for planar data transfer. Compared to the traditional method of repeatedly setting up baseplates and prisms during the measurement process of the reactor building's internal measurement control network, requiring the search for viewing holes and alignment between upper and lower layers before each measurement, and then using the lower layer's micromeasuring points for data transfer, this new device avoids the low efficiency and low accuracy caused by repeated instrument setups, eliminates the manpower consumption associated with searching for viewing holes and alignment, and effectively avoids the problem of unreliable micromeasuring point accuracy due to potential damage, deformation, or obstruction of the bottom micromeasuring points. This significantly improves work efficiency while ensuring measurement quality.

[0032] Furthermore, the device of this utility model is fixed to the top of the side wall of the steel-lined cylinder 6. During measurement, the observation is made from the top down towards the internal structure, thus bypassing the enclosure of the steel-lined cylinder 6 and solving the problem that the enclosure of the steel-lined cylinder 6 prevents the measurement from being viewed.

[0033] In summary, this utility model utilizes a transfer device that can accommodate instruments and prisms to change the traditional method of establishing a measurement and control network within the internal structure of a reactor building. This device offers a superior field of view, and its control point layout and measurement are relatively flexible, greatly improving the convenience, speed, and accuracy of establishing a measurement and control network within the reactor building. It also effectively reduces the input of manpower and resources, and the device is simple to install and easy to carry.
