Specific embodiment
Embodiments of the present invention are described with reference to the accompanying drawings of the specification.
As shown in Figure 1, the present invention devises a kind of positioning measurement dress of heat collector column suitable for slot type photo-thermal power generation
It sets, comprising: concentric adapted seat 1, measurement 3, two extension rod 2, fixing piece small prisms 4.As shown in Fig. 2, being traditional heat collector
Central point 6 is distributed in the structure of column, curved surface axle bed 5 thereon.
The present invention snugly fits to the bottom of concentric adapted seat 1 in the curved surface axle bed 5 of heat collector column completely, and same
The central point of heart adapted seat 1 is overlapped with the central point 6 of curved surface axle bed；The measurement extension rod 2 is fixed on one heart by fixing piece 3
In the guide groove of the top setting of adapted seat 1, and the center line of extension rod 2 and the center line coincidence of concentric adapted seat 1 are measured, so that
The center line for measuring the concentric adapted seat 1 of two lateral edges of extension rod 2 is symmetrical set；The two lateral edges measurement of the measurement extension rod 2
One through-hole of the symmetrical each setting in the center of extension rod 2, and two through-holes are fixed on after two small prism 4 is inserted into respectively
It is interior, measurement data is obtained by measuring two small prism 4 to realize the curved surface axle bed positioning measurement to heat collector column.
Wherein, the concentric adapted seat 1 is made according to the curved surface size of curved surface axle bed 5 using the concentric adapted seat of finishing
It obtains concentric adapted seat and represents axle bed position completely；Two small prism 4 finishes upper lower through-hole, bore size as measurement point position
It is consistent with measuring small 4 size of prism, convenient for the fixed installation of small prism 4.Measurement 2 two sides of extension rod can place two simultaneously
A small prism 4 can carry out East, West, South, North, upper and lower high accuracy positioning to 5 position of curved surface axle bed.
Preferably, the concentric adapted seat 1 and measurement extension rod 2 can be used aluminum alloy materials and be made, have it is light-weight,
The high advantage of intensity；Further, the fixing piece 3 uses bolt, and two bolt realizations can be set and firmly fix.
One embodiment of the present of invention is given below, to illustrate that apparatus of the present invention can be realized in heat collector linear array
Curved surface axle bed high accuracy positioning.
Embodiment 1,
The positioning measuring device of the present embodiment, choose first: 1, concentric adapted seat is finished, ruler using aluminum alloy materials
It is very little depending on practical curved surface axle bed, machining accuracy 0.05mm.2, extension rod is measured, is finished using aluminum alloy materials,
Length is greater than 1000mm, machining accuracy 0.05mm.3, the bolt for selecting connection, for connecting and fixing concentric adapted seat and measurement
Extension rod.4, the through-hole that small prism is placed, according to small prism locating rod size, using+0.05 to+0.1 precision aperture, aperture position
Setting precision is 0.05mm.
Then, it is installed as described above, in use, adapted seat 1 is placed in heat collector column curved surface axle bed 5 with one heart
In, and be bonded completely in curved surface, measurement extension rod 2 is installed on blending bolt in concentric 1 guide groove of adapted seat and fixes, by two small ribs
In the finishing through-hole of the insertion measurement extension rod 2 of mirror 4, by measuring the position of two small prism 4 and by calculating to curved surface axis
Seat is positioned.
The working principle of the present apparatus are as follows: entire tooling is rigid, when concentric adapted seat 1 fits in bearing block curved surface completely
When, the position of concentric adapted seat 1 is also overlapped with curved surface axle bed center position, and the coordinate position of curved surface axle bed central point is
(X, Y, the Z) known.
When specifically carrying out positioning measurement, firstly, the North and South direction of concentric adapted seat can be indicated using x-axis coordinate, east
West uses z-axis coordinate representation to using y-axis coordinate expression, elevation, i.e., the coordinate representation of concentric adapted seat is (x, y, z), by
It is overlapped in the central point of concentric adapted seat 1 with the central point 6 of curved surface axle bed, therefore x-axis and y-axis difference in the coordinate of adapted seat with one heart
Concentric adapted seat can be obtained then according to the known altitude of concentric adapted seat equal to curved surface axle bed central point X-axis, Y axis coordinate
Z-axis coordinate=curved surface axle bed central point Z axis coordinate+concentric adapted seat known altitude, therefore obtain concentric adapted seat central point
Coordinate (x, y, z).
Then, it can be converted into the theoretical coordinate of small prism putting hole according to the theoretical coordinate of concentric adapted seat, that is, obtaining
Concentric adapted seat central point coordinate (x, y, z) on the basis of, according to small prism place through-hole center and concentric adapted seat
The relative distance of central point is fixed, therefore the theoretical coordinate for the through hole center that small prism is placed can be calculated by relative distance
(x1, y1, z1).
Finally, 2 small prisms are put into through-hole, by the position of mobile curved surface axle bed, 2 are measured using total station survey
The measurement coordinate (x2, y2, z2) of small prism, judge the measurement coordinate (x2, y2, z2) and theoretical coordinate (x1, y1, z1) whether phase
Symbol, is consistent, and does not need adjustment curved surface axle bed position, otherwise in the position for not being consistent time shift moving surface axle bed, while observing its seat
Mark stops adjustment when being equal to theoretical coordinate (x1, y1, z1).As a result, the actual measurement coordinate of small prism reaches theoretical coordinate,
Curved surface axle bed reaches theoretical position, and the measurement coordinate of the measurement point formed by two small prism is achieved that curved surface axle bed
Coordinate setting, can accurately embody East, West, South, North, the upper and lower position of curved surface axle bed.
To sum up, positioning measuring device of the invention can facilitate the geometric center of determining heat collector curved surface axle bed axis, to thermal-arrest
Each curved surface axle bed of device column is accurately positioned, and guarantees that heat collector column East, West, South, North and elevation location are accurate, so that peace
Curved surface axle bed concentricity loaded on heat collector column meets required precision, is widely portable to thermal-arrest in slot type photo-thermal power generation project
The positioning measurement of device column array uses.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be without departing from the purpose of the present invention
It makes a variety of changes.
