Description
Technical Field
The invention relates to the field of nuclear reactors, in particular to a fixing support for a neutron temperature measurement channel.
Background
Due to the fact that the neutron temperature measuring channel needs to be pulled out and fixed on the transportation platform when the material is changed during overhaul, the neutron temperature measuring channel is installed back to the fuel assembly from the transportation platform after the material is changed, and in order to guarantee that the neutron temperature measuring channel is reliably fixed during the period, the fixing method of the neutron temperature measuring channel on the transportation platform needs to be considered.
Transportation platform has reserved 18 holes (including a personnel's passageway) in the design and has been used for extracting and installing of neutron temperature measurement passageway, and each hole can realize 3 neutron temperature measurement passageway's installation and dismantlement, according to the design of russia earlier stage, the mode of adoption utilizes the string ligature, fixes in transportation platform first layer rail department.
The existing fixing mode is extremely not beneficial to the installation and the disassembly of the neutron temperature measuring channel, in the installation and disassembly work, the neutron temperature measuring channel is longer and has certain bending, the fixing method can easily cause the staggered winding of 3 neutron temperature measuring channels below the first layer platform, the collision of the neutron temperature measuring channel part above the neutron temperature measuring channel part is severe, the neutron temperature measuring channel is further damaged, unnecessary economic loss is caused, meanwhile, the staggered winding of the neutron temperature measuring channel easily causes the condition that the installation position is wrong when people install, and the situation is also the incentive of people due to the mistake.
Based on the above situation, an effective way must be adopted to firmly and orderly fix the neutron temperature measurement channel on the transportation platform.
Disclosure of Invention
The invention aims to provide a fixing support for a neutron temperature measuring channel, so that the neutron temperature measuring channel can be stably and orderly fixed on a transportation platform.
In order to solve the technical problem, the fixing support for the neutron temperature measurement channel comprises a base, a supporting rod fixed inside the base and a plurality of dispersed fork openings fixed at the upper end of the supporting rod, wherein a plurality of installation preformed holes are circumferentially distributed on the outer side of the base, the number of the installation preformed holes is the same as the number of the dispersed fork openings, and the connecting line of the installation preformed holes and the external port of the dispersed fork openings is parallel to the supporting rod.
The base comprises a plurality of circular arcs and a circular supporting steel plate fixed on the circular arcs, and a plurality of mounting preformed holes are circumferentially distributed on the circular supporting steel plate; the support rod 4 is fixed inside the circular arc through a cross rod.
The number of the installation preformed holes and the number of the dispersed fork openings are 3.
The circle formed by the circular arc is smaller than the hole of the transportation platform.
The invention has the beneficial technical effects that: after this fixed bolster is put into use, each passageway is arranged in order on transport platform, and the lower part dispersion is obvious, the effectual problem of solving the passageway damage that crisscross winding caused, has greatly reduced because of personnel judge the probability that the mistake caused passageway position installation error, and upper portion receives the influence of this fixed bolster, does not have the phenomenon of collision each other between each passageway.

FIG. 2 shows the mounting effect of a fixing bracket for a neutron temperature measurement channel according to the present invention.
In the figure: 1 is the circular arc, 2 is circular supporting steel sheet, 3 is the installation preformed hole, 4 is the bracing piece, 5 is the dispersion fork mouth, 6 is neutron temperature measurement passageway, 7 is the transportation platform.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the fixing bracket for a neutron temperature measuring channel of the invention comprises a base, a supporting rod 4 fixed in the base in a welding manner, a plurality of dispersed fork 5 fixed at the upper end of the supporting rod 4, a plurality of mounting preformed holes 3 distributed on the outer side of the base in the circumferential direction, the number of the mounting preformed holes 3 is the same as that of the dispersed fork 5, and the connecting line of the mounting preformed holes 3 and the external port of the dispersed fork 5 is parallel to the supporting rod 4.
The base comprises a plurality of circular arcs 1 forming a circle and a circular supporting steel plate 2 fixed on the circular arcs 1, and a plurality of mounting preformed holes 3 are circumferentially distributed on the circular supporting steel plate 2; the support rod 4 is fixed inside the arc 1 by welding through a cross rod.
The number of the mounting prepared holes 3 and the dispersion fork 5 may be 3.
The circular support steel plate 2 and the support rod 4 are preferably coaxial.
The fixed support is made of steel, the material is low in price and good in stability, and the neutron temperature measuring channel 6 can be effectively fixed on the transportation platform 7.
Three steel arcs 1 are distributed on the lower part of the base according to a circle, the formed circle is slightly smaller than the hole of the transportation platform, and the fixed support can be stably installed in the hole when being installed; the upper part of the base is composed of a supporting circular steel plate 2, the three directions of the base are respectively reserved with an installation reserved hole 3 of the neutron temperature measurement channel, the position of the hole is just positioned at the edge of the hole of the transportation platform, the hole is intersected with the hole of the transportation platform, the diameter of the lower part of the neutron temperature measurement channel is reserved in the size aspect, the installation of the neutron temperature measurement channel is convenient, meanwhile, the reserved hole is smaller than the diameter of the upper part of the neutron temperature measurement channel, the diameter of the upper part of the neutron temperature measurement channel is larger than the diameter of the lower part, when the channel is installed in place, the channel is influenced by gravity, and the channel is just supported on the steel plate.
Bracing piece and 3 dispersion fork openings play the effect of dispersion neutron temperature measurement passageway, and its angle keeps unanimous with the hole angle that is reserved to the lower part base, and dispersion fork opening and the laminating of neutron temperature measurement passageway upper portion have been solved in this design the problem of neutron temperature measurement passageway installation in order.
When the neutron temperature measuring device works, the three neutron temperature measuring channels 6 are bound by cloth strips or strings around the supporting rods, so that the channels can be attached to the fixing support, and the channels are arranged orderly; after the whole fixed support and the neutron temperature measurement channel are installed in place on the transportation platform, the installation is stable, the installation among the channels is orderly, and the problems of staggered winding and mutual collision of the neutron temperature measurement channel can be effectively solved.
