Description

Technical Field

[0001] The utility model belongs to the technical field of offshore wind power foundation monitoring, and in particular relates to an auxiliary device for installing an offshore wind turbine foundation monitoring stress gauge. Background Art

[0002] In the field of offshore wind turbine foundation safety monitoring, it is necessary to use stress gauge devices for long-term measurement of monitoring points, and the stress gauge installation support, referred to as the support, is an important component of the measurement point. In order to avoid high temperature damage to the instrument during welding, a simulated rod with the same diameter and length as the strain gauge has long been used to replace the strain gauge for coaxial welding when welding the support. However, due to the needs of corrosion protection and waterproofing, the offshore wind turbine foundation stress gauge will be welded with a protective box in advance at the strain gauge installation position. The existence of the protective box limits the space for removing the simulated rod after the support is welded. Secondly, the support will deform during welding, generating great friction, and the simulated rod has no fulcrum on the surface, which makes it impossible to remove the simulated rod with the help of external force. The support can only be cut and adjusted and then re-welded.

[0003] Therefore, a new type of strain gauge installation auxiliary device is needed to replace the existing simulation rod for support fixing welding. Utility Model Content

[0005] The technical solution adopted by the utility model is an auxiliary device for installing an offshore wind turbine foundation monitoring stress gauge, including a simulation rod, wherein two ends of the simulation rod are respectively connected to a support a and a support b, a horizontal through hole is opened in the middle of the support a, a groove is opened in the upper part of the support b, one end of the simulation rod passes through the through hole, and the other end of the simulation rod is arranged in the groove, and the simulation rod includes a fixed end a, a waist rod a, a middle end of the simulation rod, a waist rod b and a fixed end b which are coaxially fixed in sequence, and the diameters of the waist rod a and the waist rod b are smaller than the diameters of the fixed end a, the middle end of the simulation rod and the fixed end b.

[0006] The utility model is also characterized in that:

[0007] The simulation rod is coaxially arranged with the support a and the support b.

[0008] The fixed end a matches with the through hole, and the fixed end b matches with the groove.

[0009] The side wall of the support a is penetrated with a screw a, and the inner end surface of the screw a is in top contact with the fixed end a.

[0010] The side wall of the support b is penetrated by a screw b, and the inner end surface of the screw b is in top contact with the fixed end b.

[0011] The diameters of the fixed end a, the middle end of the simulation rod and the fixed end b are consistent, and the diameters of the waist rod a and the waist rod b are consistent.

[0012] The beneficial effects of the utility model are:

Since the diameters of the waist rod a and the waist rod b in the simulation rod are smaller than the diameters of the fixed end a, the middle end of the simulation rod and the fixed end b, when the simulation rod is pulled out along the inside of the through hole, the waist rod b moves into the inside of the groove, and the diameter of the waist rod b is smaller than the size of the groove, the simulation rod can be smoothly taken out upwards, and then the stress gauge can be placed inside the support, which can effectively solve the problem that the simulation rod is not easy to take out after the ordinary simulation rod is fixed to the support and welded.

[0017] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0018] Offshore wind turbine foundation monitoring stress gauge installation auxiliary device, such as Figure 1 As shown, it includes a simulation rod 1, and the two ends of the simulation rod 1 are connected to the support a2 and the support b3 respectively. The middle of the support a2 is provided with a through hole 202 that runs horizontally through, and the upper part of the support b3 is provided with a groove 302. One end of the simulation rod 1 passes through the through hole 202, and the other end of the simulation rod 1 is arranged in the groove 302. The simulation rod 1 is coaxially arranged with the support a2 and the support b3. Figure 2The simulation rod 1 includes a fixed end a101, a waist bar a102, a simulation rod middle end 103, a waist bar b104 and a fixed end b105 which are coaxially fixed in sequence. The diameters of the waist bar a102 and the waist bar b104 are smaller than the diameters of the fixed end a101, the simulation rod middle end 103 and the fixed end b105. The diameters of the fixed end a101, the simulation rod middle end 103 and the fixed end b105 are consistent. The diameters of the waist bar a102 and the waist bar b104 are consistent. Such a structure is designed to make it easier for the simulation rod to be removed from the inside of the support.

[0019] like Figure 1 As shown, the fixed end a101 cooperates with the through hole 202, and the fixed end a101 can reciprocate along the inner wall of the through hole 202; the fixed end b105 cooperates with the groove 302, so as to ensure that the fixed end b105 fits the inner wall of the groove 302 and prevent the fixed end b105 from loosening inside the groove 302;

[0020] The side wall of the support a2 is penetrated with a screw a201, the inner end surface of the screw a201 is in contact with the fixed end a101, and the screw a201 has the function of fixing the fixed end a101 in the simulation rod 1. By tightening the screw a201, the fixed end a101 is fixed inside the through hole 202 to prevent the fixed end a101 from loosening;

[0021] A screw b301 is inserted into the side wall of the support b3, and the inner end surface of the screw b301 is in contact with the fixed end b105. The screw b301 has the function of fixing the fixed end b105 in the simulation rod 1. By tightening the screw b301, the fixed end b105 is fixed inside the groove 302 to prevent the fixed end b105 from loosening.

[0022] The utility model offshore wind turbine foundation monitoring stress gauge installation auxiliary device, its working process is: first, the simulation rod 1 is coaxially fixed with the support a2 and the support b3, specifically, the fixed end a101 is inserted into the through hole 202, and the screw a201 is tightened to fix it, the fixed end b105 is placed in the groove 302, and the screw b301 is tightened to fix it, to ensure that the simulation rod 1, the support a2 and the support b3 are coaxial; then the support a2, the support b3 and the simulation rod 1 are placed at the installation position of the instrument for welding, and the support a2 is welded after the welding is completed. After the support b2 and the support b3 have cooled, loosen the screws a201 and the screw b301, pull out the fixed end b105 along the inner wall of the groove 302, and pull out the simulation rod 1 from the inside of the through hole 202. After the waist bar b104 enters the inside of the groove 302, the diameter of the waist bar b104 is smaller than the size of the groove 302, and the simulation rod 1 can be smoothly taken out upwards. When the two supports are deformed and the simulation rod 1 cannot be taken out normally due to the force, the waist bar a102 of the simulation rod 1 can be clamped by tools such as rubber-handled pliers and fit with the middle end 103 of the simulation rod, and the rubber-handled pliers can be tapped along the removal direction to take out the simulation rod 1. After the simulation rod 1 is taken out, the stress gauge is placed inside the support a2 and the support b3, so as to achieve the purpose of facilitating the removal of the simulation rod 1. In the above manner, the problem that the simulation rod is not easy to take out after the ordinary simulation rod is fixed to the support and welded in the prior art can be solved very well.
