Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Embodiments of the present invention provide a leak repair apparatus that includes a repair assembly, a gasket, and a pressure plate for assembly with the repair assembly in a compression configuration during a repair process. Wherein, repair the sub-assembly and include bolt, nut, pivot and arc steel pipe.
Referring to fig. 1, fig. 1 is three views of a repair assembly provided by an embodiment of the present invention, fig. 1 (a) is a front view of the repair assembly, fig. 1 (b) is a rear view of the repair assembly, and fig. 1 (c) is a left side view of the repair assembly.
As shown in fig. 1, repair assembly 100 includes bolt 101, nut 102, shaft 103, and curved steel tube 104.
Referring to fig. 2 for the arc-shaped steel pipe 104, fig. 2 is a schematic view of an arc-shaped steel pipe provided in an embodiment of the present invention, in a possible implementation manner, the arc-shaped steel pipe 104 may be obtained by longitudinally cutting the steel pipe, and when cutting the steel pipe, it is required to ensure that not only the diameter of the arc-shaped steel pipe 104 obtained after cutting is smaller than the diameter of the leakage hole, but also the bolt 101 can rotate along with the rotation of the rotating shaft 103. The diameter of the arc-shaped steel pipe 104 is smaller than that of the leakage hole so that the arc-shaped steel pipe 104 can be inserted into the leakage hole. The length of the arc-shaped steel pipe 104 is greater than the diameter of the leakage hole, for example, the length of the arc-shaped steel pipe 104 may be directly 8-10 times of the leakage hole, so that the arc-shaped steel pipe 104 is not pulled out from the leakage hole in a vertical state.
For bolt 101 and nut 102, bolt 101 is in mating connection with nut 102.
For the rotating shaft 103 and the arc-shaped steel pipe 104, the rotating shaft 103 penetrates into the inner cavity of the arc-shaped steel pipe 104 from the outer wall of one side of the arc-shaped steel pipe 104, and penetrates out from the outer wall of the other side of the arc-shaped steel pipe 104.
In one possible implementation, the position of the shaft hole of the rotating shaft 103 is deviated from the center position of the arc-shaped steel pipe 104 in the length direction. The shaft hole of the rotating shaft is arranged at the center position deviated from the length direction of the steel pipe, so that after the arc-shaped steel pipe is inserted into the storage tank, the arc-shaped steel pipe can automatically droop under the action of gravity and is vertical to the bolt.
For the bolt 101 and the rotating shaft 103, the bolt 101 is vertically and fixedly connected to the rotating shaft 103. In one possible implementation, the bolt 101 is welded perpendicularly to the shaft 103. Through adopting the welded mode, with bolt vertical fixation in the pivot, increased the fastness of being connected between bolt and the pivot.
In addition, the bolt 101 can rotate with the rotation of the rotation shaft 103. When the bolt 101 rotates along with the rotation shaft 103 to a direction coaxial with the arc-shaped steel pipe 104, that is, to be horizontal with the arc-shaped steel pipe 104, the repairing assembly 100 is folded. It can be seen that the repair assembly 100 is an assembly of a collapsible type.
When the bolt 101 rotates along with the rotating shaft 103 to a direction perpendicular to the arc-shaped steel pipe 104, that is, to the arc-shaped steel pipe 104, the bolt 101 and the arc-shaped steel pipe 104 form a "T" structure, so that the arc-shaped steel pipe 104 can be hung on one side of the leakage hole. It can be seen that repair assembly 100 is a "T" shaped leak hole hanger.
The diameter of the bolt 101 and the length of the rotating shaft 103 are smaller than the diameter of the leakage hole, so that when the bolt 101 is rotated to be horizontal to the arc-shaped steel pipe 104, the diameter of the bolt 101 and the length of the rotating shaft 103 are smaller than the diameter of the leakage hole, so that the arc-shaped steel pipe 104 can be completely inserted into the storage tank. Alternatively, the diameters of the arc-shaped steel pipe 104 and the bolt 101 may be matched with the tensile strength of the material in addition to the size of the leakage hole, and of course, the diameter of the rotating shaft 103 may also be matched with the tensile strength of the material, for example, the larger the tensile strength of the material is, the smaller the diameters of the arc-shaped steel pipe 104, the rotating shaft 103 and the bolt 101 are.
For bolt 101 and arc steel tube 104, in one possible implementation, the length of bolt 101 is greater than one-half of the length of arc steel tube 104. Therefore, when the bolt is rotated to be horizontal to the steel pipe, a part of the bolt is left outside, and the operation is convenient.
In one possible implementation, the gasket 200 is made of rubber, and the pressing plate 300 and the bolt 101 are made of steel. By selecting steel as the material, the tensile strength of the material can be ensured.
Referring to fig. 3, fig. 3 is a schematic diagram of a compression structure of a leakage repairing apparatus according to an embodiment of the present invention, and as shown in fig. 3, the leakage repairing apparatus includes a repairing assembly 100, a gasket 200, and a pressure plate 300. The arc-shaped steel pipe of the repair assembly 100 is located at the inner side of the tank to be repaired, and the gasket 200 and the pressing plate 300 are located at the outer side of the tank to be repaired.
Wherein the size of the gasket 200 and the pressing plate 300 is larger than the size of the leakage hole of the storage tank to be repaired, so that it can be ensured that the gasket and the pressing plate 300 can completely cover the leakage hole. For example, the size of the gasket 200 and the pressure plate 300 is generally 10 times or more the size of the leakage hole.
Alternatively, the dimensions of the gasket and the pressure plate may be adapted to the location of the leakage hole in addition to the dimensions of the leakage hole, for example, when the leakage hole is located at a specific location of the tank, such as close to the bottom of the tank, due to the obstruction of the bottom, the dimensions of the gasket and the pressure plate need to be adapted to the specific location of the leakage hole, such as the dimensions of the gasket and the pressure plate are not too large.
The gasket 200 is provided with a first through hole, the pressing plate 300 is provided with a second through hole, the diameters of the first through hole and the second through hole can be selected according to the diameter of the bolt 101, if the diameters of the first through hole and the second through hole can be matched with the diameter of the bolt 101, the gasket 200 and the pressing plate 300 can be threaded on the bolt, and gaps can not appear at the joint of the gasket, the pressing plate and the bolt.
After the assembly is completed, the gasket 200 is connected with the bolt 101 of the repair assembly through the first through hole, the pressing plate 300 is connected with the bolt 101 of the repair assembly through the second through hole, the pressing plate 300 is pressed on the outer side of the gasket 200, the nut 102 is connected with the bolt 101 in a matching way, and the nut 102 is pressed on the outer side of the pressing plate 300. Thus, the gasket, the pressing plate and the repairing assembly are assembled into a pressing structure, and the effect of completely sealing the leakage hole can be achieved.
The repair process is described below, including assembling the shim 200 and the platen 300 with the repair assembly 100 in a compression configuration during the repair process. In one possible implementation, the repair process may be as follows: rotating a bolt 101 on the repairing assembly 100 around a rotating shaft 103 to be horizontal to an arc-shaped steel pipe 104, then inserting the arc-shaped steel pipe 104 into a leakage hole of a storage tank to be repaired, ensuring that the arc-shaped steel pipe 104 is completely inserted into the storage tank, rotating the bolt 101 on the repairing assembly 100 around the rotating shaft 103 to be vertical to the arc-shaped steel pipe 104, further connecting a gasket 200 with the bolt 101 through a through hole of the gasket, connecting a pressing plate 300 with the bolt 101 through a through hole of the pressing plate, namely sequentially penetrating the gasket 200 and the pressing plate 300 on the bolt 101, and finally, using a nut 102 on the repairing assembly 100 to be matched and connected with the bolt 101 until the bolt is screwed down.
According to the leakage repairing device provided by the embodiment of the invention, the bolt on the repairing assembly can rotate along with the rotation of the rotating shaft, so that the arc-shaped steel pipe of the repairing assembly can be inserted into the leakage hole to be repaired by rotating the bolt to be horizontal to the arc-shaped steel pipe in the repairing process, the bolt can be rotated to be vertical to the arc-shaped steel pipe after the arc-shaped steel pipe is completely inserted into the storage tank, the arc-shaped steel pipe can cover the leakage hole on the inner wall of the storage tank, then the leakage hole is sealed on the outer wall of the storage tank through the gasket, the gasket is pressed through the pressing plate, finally the pressing plate is pressed through the nut, and the gasket and the pressing plate are assembled into a pressing structure with the repairing assembly in the repairing process, so that the leakage hole can be. The leakage repairing device can be used for temporarily repairing a leaked storage tank, production stop, decontamination, oil removal and rust removal are not needed, normal operation of system production can be guaranteed, potential safety hazards can be reduced, and the repairing scheme is low in cost, short in time and easy to realize.
