Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention. It should be apparent that the described embodiment is one embodiment of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
It is to be noted that technical terms or scientific terms used herein should have the ordinary meaning as understood by those having ordinary skill in the art to which the present invention belongs, unless otherwise defined.
The meaning of "a plurality" in the description of embodiments of the invention is at least two, e.g., two, three, etc., unless explicitly specified otherwise.
The embodiment of the application provides a protection casing for a cladding pipe internal pressure blasting test device. It will be readily appreciated that since the cladding tube is radioactive, the in-cladding tube pressure burst test apparatus is typically located in a hot room, with the use of the in-cladding tube pressure burst test apparatus being controlled by a robot by an operator outside the hot room.
Referring to fig. 1 to 3, the shield 10 of the embodiment of the present application includes: two half-shells 11, a hinge 12, and at least one locking member 13.
The half shell 11 has a lateral opening 111 and a bottom opening 112 communicating with the lateral opening 111. The lateral openings 111 of the two half-shells 11 are arranged opposite one another. It will be readily appreciated that the lateral openings 111 are located on the sides of the half-shell 11 and the bottom opening 112 is located on the bottom of the half-shell 11.
The hinge member 12 is used to hinge the two half cases 11 at one side edge of the lateral opening 111 of each half case 11 so that the relative positional state of the two half cases 11 can be switched between the open state and the closed state. When the two half-shells 11 are in a closed state, the two half-shells 11 together form a shell capable of enclosing a pressure interface of the shell internal pressure explosion testing device and a test sample connected with the pressure interface in a sealing mode. When the two half shells 11 are in the open state, the two half shells 11 can be separated from the pressure interface and the test sample.
Since the lateral openings 111 of the two half shells 11 are opposite and hinged at one side of the lateral opening 111, when the two half shells 11 are in the closed state, the lateral openings 111 of the two half shells 11 are closed, forming a closed shell. At this time, the bottom openings 112 of the two half shells 11 together form the bottom opening of the shield 10. In other words, when the two half shells 11 are in the closed state, the protective cover 10 forming the closure has a bottom opening, so as to allow the pressure port located on the base of the cladding internal pressure burst test device and the test sample sealingly connected to the pressure port to be covered by the protective cover 10.
At least one locking member 13 is configured to be operated by a robot inside the hot room to lock the two half shells 11 when the two half shells 11 are in the closed condition.
The protection casing 10 that this application embodiment provided for before the test sample utilizes the test device of the intraductal pressure blasting of cladding to carry out the blasting test, including establishing the test sample cover to can prevent after the test sample blasting that the sample that breaks from splashing everywhere, damage test device inner part of the intraductal pressure blasting of cladding, and do benefit to the collection of breaking the sample after the experiment.
In addition, compared with the protection cover which is fixed as an integral type, the split type protection cover 10 formed by hinging the two half-cover shells 11 is convenient for workers to operate the mechanical arm outside a hot chamber to assemble the protection cover 10 and other parts of the cladding tube internal pressure explosion testing device. And, after the test sample explodes, the protection cover 10 can be conveniently detached by a worker operating the mechanical arm outside the hot chamber, and the sample after the test can be collected.
Referring to fig. 1, in some embodiments, the hinge member 12 includes a hinge hole 121 fixed to one half casing 11 and a hinge shaft 122 fixed to the other half casing 11, and the hinge of the two half casings 11 is achieved by the cooperation of the hinge shaft 122 and the hinge hole 121.
In some embodiments, the hinge 12 may be a hinge or other structure that enables articulation.
In some embodiments, two half shells 11 are disposed side-to-side. The two half shells 11 are connected at the side of the half shells 11 by a hinge 12, so that the two half shells 11 can be opened and closed along the sideline position.
The embodiment of the application is provided with the locking piece 13, so that the two half housings 11 can be prevented from being knocked open by splashed samples after blasting in the closed state.
In some embodiments, the half shells 11 are semi-circular arc shaped shells, and when the two half shells 11 are in the closed state, the two half shells 11 together form a cylindrical shell with an open bottom.
In some embodiments, the half-shell 11 comprises: an upper half shell 113, a lower half shell 114, and a connecting section 115.
The lower half shell 114 is disposed below the upper half shell 113, and the connecting section 115 connects the upper half shell 113 and the lower half shell 114. The inner diameter of lower half shell 114 is greater than the inner diameter of upper half shell 113. The hinge members 12 are provided at the side of the lower half shell 114 of each half shell 11.
In some embodiments, the upper face of the pressure port of the cladding tube internal pressure burst test device is substantially flush with the lower face of the upper half-shell 113, such that the test specimen is opposite the front face of the upper half-shell 113. Since the inner diameter of the lower half shell 114 is larger than that of the upper half shell 113, and the upper end surface of the pressure interface of the cladding tube internal pressure burst test device is substantially flush with the lower end surface of the upper half shell 113, when the test sample bursts, fragments are facilitated to be ejected into the lower half shell 114 after colliding with the upper half shell 113, and are collected in the lower half shell 114.
It is easy to understand that the circumferential inner wall of the liftable shell of the cladding tube internal pressure explosion test device is provided with a heating element for heating a test sample through heat radiation.
In some embodiments, the upper half-shell 113 is a hollow structure to facilitate heat radiation from the heating element located outside the circumferential direction of the upper half-shell 113 to the test sample.
Referring to fig. 1 and 2, in some embodiments, upper half-shell 113 defines a plurality of holes 1131, and holes 1131 are divided into two rows on upper half-shell 113. For each hole 1131, its vertical dimension is greater than its lateral dimension. For example, the vertical dimension may be 3-10 times the lateral dimension. So design can enough be favorable to the heating member to pass through the thermal radiation to the sample that tests as far as possible and heat, can guarantee half upper shell 113's intensity again, prevents to take place to buckle when the sample explodes.
The other side of the lower half-shell 114, opposite to the side provided with the hinge 12, is provided with at least one locking fitting 116. The locking member 13 cooperates with the locking fitting 116 to lock the two half shells 11. The side on which the hinge 12 is provided may be referred to as a hinge side of the hood 10, and the other side opposite to the side on which the hinge 12 is provided may be referred to as an open side or a free side.
In some embodiments, one or both sides of the upper shell half 113 are also provided with at least one locking fitting 116 to further increase the strength of the shield 10 to ensure that the two shell halves 11 are not knocked apart by splashed sample under impact.
In some embodiments, the locking engagement 116 is an L-shaped lug.
Referring to fig. 4, the locking member 13 includes a ring portion 131 and a grasping portion 132 connected to the ring portion 131, wherein the grasping portion 132 is used for a robot to grasp to fit the ring portion 131 on a pair of L-shaped lugs corresponding to the two half cases 11 and to take out the ring portion 131 from the pair of L-shaped lugs.
In some embodiments, a plurality of locking fittings 116 are provided on the other side (i.e., the open or free side) of the lower housing half 114 opposite the side on which the hinge 12 is disposed. For example, the other side may be provided with 2, 3, 4 or more locking fittings 116.
In some embodiments, both sides of the upper half-shell 113 may be provided with a plurality of locking fittings 116, respectively. For example, both sides of the upper half shell 113 may be provided with 2, 3, 4 or more locking fittings 116, respectively.
In some embodiments, half-shell 11 further comprises: and a flange 117 extending outwardly from the lower end surface of the lower half shell 114 for pressing the outer shell of the cladding tube internal pressure burst test apparatus against the flange 117.
In the embodiment of the present application, after the apparatus for testing the inner pressure burst of the cladding pipe is assembled, the liftable outer shell of the apparatus for testing the inner pressure burst of the cladding pipe presses the flange 117, thereby preventing the shield 10 from being lifted up by the splashed sample under impact. The embodiment of the application realizes that the protective cover 10 is fixed by arranging the flange 117 on the half-shell 11 and pressing the flange 117 downwards by utilizing the liftable shell, and the device is very convenient for the inner pressure burst test device of the shell tube assembled by a mechanical arm in a hot room.
It will be readily appreciated that, in order to ensure that the relative position of the two half shells 11 can be switched between the open condition and the closed condition, the angle formed between the portions of the two flanges 117 located on the hinged side is formed. So that when the two half shells 11 are opened from the closed condition, no interference occurs between the two flanges 117, thus allowing relative rotation between the two half shells 11.
In some embodiments, the lower half-shell 114 of one of the two half-shells 11 is provided with an operating portion 118 for the robotic operation in the heating chamber to open the two half-shells 11. In some embodiments, the lower half-shells 114 of both half-shells 11 are provided with an operating portion 118.
In some embodiments, the handling portion 118 may be a raised structure extending outwardly from an outer side surface of the lower housing half 114. In some embodiments, the operating portion 118 may also have a handle structure to facilitate robotic operation.
The operating portion 118 may be disposed at the circumferential middle portion of the lower half shell 114, that is, the operating portion 118 is substantially the same distance from both side edges of the half shell 11, so that when the protection cover 10 is disassembled after the test is completed, the side edges of the half shell 11 can be made to face the operator for the operator to observe, and at the same time, the operator can conveniently control the manipulator to grip the operating portion 118, so as to open the two half shells 11. Since the side edge of the half cover 11 faces the operator, when the operator moves the half cover 11 in the open state away from the base 50 by the manipulator, the operator can observe the test sample 200 and the position of the pressure interface 40 conveniently, so as to prevent the half cover 11 from scratching the pressure interface 40 or being scratched by the test sample 200 during the evacuation process.
