Description

Technical Field

[0001] The present invention relates to the technical field of equipment installation, and in particular to a calibration device. Background Art

[0002] In recent years, with the increasing efforts in offshore oil exploration and development, jacket offshore platforms have been widely used in offshore oil exploration and development due to their high rigidity, good overall stability, low cost, convenient construction, and wide range of applications.

[0003] During its service life, the jacket platform has been subjected to harsh environmental influences such as wind, waves, currents, and sea ice. The changes in the local water flow dynamic field around the platform pile foundation have caused the scouring of the seabed soil layer, which has reduced the platform pile foundation capacity, causing uneven settlement of the platform and resulting in different damages. In order to ensure the safe operation of the jacket platform, sensors need to be deployed at key locations to monitor the uneven settlement and tilt of the platform in real time. However, each sensor must be at the same height during installation, which requires calibration of the sensor installation position.

[0004] At present, there are two main methods for calibrating the sensor installation position: (1) Assuming that the platform deck surface is horizontal, the platform deck is used as a reference, and the same height is measured to determine the sensor installation position. However, in practice, there is a certain height difference due to factors such as processing, installation, and load-bearing, which leads to inaccurate sensor installation positions; (2) Using a total station for calibration, but in actual operation, it is easily obstructed by platform components, equipment and facilities, pipes and cables, and cannot be calibrated directly. Measurements need to be made through a transfer station, which is time-consuming and labor-intensive. Summary of the invention

[0020] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figure 1 to Figure 2 , the figure shows the preferred structure of the calibration device in this embodiment. As shown in the figure, the calibration device includes: a connecting tube 1, two measuring cylinders 2 and two marking devices 3. Among them, each measuring cylinder 2 is provided with a scale line, and each measuring cylinder 2 can be made of a transparent material for easy observation.

[0022] The two ends of the connecting tube 1 correspond to the two measuring cylinders 2 one by one, and each end of the connecting tube 1 is connected to the corresponding measuring cylinder 2, so that the connecting tube 1 and the two measuring cylinders 2 form a U-shaped structure. The interior of the connecting tube 1 and the interiors of the two measuring cylinders 2 are connected to form a connecting space, and the connecting space contains liquid, and the liquid can flow between the interior of the connecting tube 1 and the interiors of the two measuring cylinders 2. In specific implementation, the liquid can be water or a colored liquid for easy observation, and this embodiment does not impose any restrictions on this.

[0023] The two measuring cylinders 2 are respectively used to be placed at the preset positions of the two pile legs. The two pile legs can be two adjacent pile legs or two pile legs set at intervals. This embodiment does not impose any restrictions on this. The preset position of the pile leg is the designed installation position of the sensor on the pile leg, but the designed installation position needs to be calibrated by a calibration device, and the final installation position is determined before the sensor is installed. After calibration, the installation positions of each sensor need to be kept at the same height. The position of one of the measuring cylinders 2 remains stationary, and the other measuring cylinder 2 is used to adjust its own height so that the liquid level scales of the two measuring cylinders 2 are the same. Specifically, the staff manipulates the position of the other measuring cylinder 2 so that the liquid flows in the connected space until the liquid level scales of the liquid in the two measuring cylinders 2 are the same. Then the liquid level scale corresponds to the position of the pile leg, which is the installation position of the sensor, and can ensure that the installation positions of the sensors on the two pile legs are at the same height.

[0024] The two marking devices 3 correspond to the two measuring cylinders 2 one by one, and each marking device 3 can be movably arranged on the corresponding measuring cylinder 2, that is, each marking device 3 can be moved up and down on the corresponding measuring cylinder 2 to adjust the position of the marking device 3 on the measuring cylinder 2. Each marking device 3 is used to mark on the respective legs when the liquid level scales of the two measuring cylinders 2 are the same, and the marked position is the installation position of the sensor.

[0025] It can be seen that in the present embodiment, the connecting tube 1 is connected with the two measuring cylinders 2 to form a connecting space for accommodating liquid, one of the measuring cylinders 2 is placed at a preset position of the pile leg, and the position of the other measuring cylinder 2 is adjusted. When the liquid level scales of the measuring cylinders 2 are the same, the two marking devices 3 are marked on their respective pile legs, and the marked position is the installation position of the sensor, which can effectively ensure that the installation positions of the sensors on the two pile legs are at the same height, ensure that the installation position of the sensor is accurately calibrated, reduce errors, simplify operation, save time and effort, and solve the problem of inaccurate and time-consuming calibration of the sensor installation position in the prior art.

[0026] See also Figure 1 In the above embodiment, each measuring cylinder 2 is L-shaped, the first end of each measuring cylinder 2 is perpendicular to the second end, and the first end of each measuring cylinder 2 ( Figure 1The upper end shown in the figure is detachably provided with a cover body 5, and the second end of each measuring cylinder 2 is connected to the corresponding end of the connecting pipe 1.

[0027] Preferably, the connecting pipe 1 is a hose with a preset length, and the preset length can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. In this embodiment, the preset length is the distance between the two pile legs, so that when calibrating, the hose is straight, avoiding the hose from sagging due to being too long.

[0028] During specific implementation, the hose can be made of an ordinary plastic water pipe or a rubber pipe. Of course, it can also be made of other materials, and this embodiment does not impose any limitation on this.

[0029] Each end of the hose is sleeved on the second end of the corresponding measuring cylinder 2 and is locked by the fastener 4, so that the hose is connected to the measuring cylinder 2. Preferably, the fastener 4 is a clamp.

[0030] It can be seen that in this embodiment, the connection structure between the measuring cylinder 2 and the connecting tube 1 is simple and easy to implement.

[0031] See also Figure 1 In the above embodiments, each marking device 3 may include: a marking pen 31, an elastic member, two arc-shaped bodies 32 and two mounting plates 33. Among them, the two arc-shaped bodies 32 are arranged opposite to each other, and the first ends of the two arc-shaped bodies 32 correspond to the two ends of the elastic member one by one, and the first end of each arc-shaped body 32 is connected to the corresponding end of the elastic member, then the two arc-shaped bodies 32 and the elastic member are surrounded by a clamping space, and the clamping space is used to clamp the measuring cylinder 2. Specifically, the arc shape of each arc-shaped body 32 matches the shape of the measuring cylinder 2, and the elastic member has a preset length, which can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. After the measuring cylinder 2 is clamped in the clamping space, the elastic member is in an extended state, and the two arc-shaped bodies 32 and the elastic member stably clamp the measuring cylinder 2 by relying on the elastic restoring force of the elastic member.

[0032] The two mounting plates 33 are parallel and in contact with each other. The two mounting plates 33 correspond to the second ends of the two arc-shaped bodies 32 one by one, and each mounting plate 33 is connected to the second end of the corresponding arc-shaped body 32. The two mounting plates 33 are placed outside the clamping space, and each mounting plate 33 is parallel to the height direction of the measuring cylinder 2. After the measuring cylinder 2 is clamped in the clamping space, the two mounting plates 33 are in relative contact. Each mounting plate 33 is provided with a through hole, and the positions of the through holes on the two mounting plates 33 are the same. The marking pen 31 is sequentially penetrated through the two through holes, so that the marking pen 31 is perpendicular to the pile leg, which is convenient for the marking pen 31 to mark on the pile leg.

[0036] The ends of the two outermost branches 11 are connected to the two measuring cylinders 2 in a one-to-one correspondence. Specifically, the left end of the leftmost branch 11 is connected to the corresponding measuring cylinder 2, and the right end of the rightmost branch 11 is connected to another measuring cylinder 2.

[0037] Preferably, each branch pipe 11 is a hose, and the end of the outermost branch pipe 11 is sleeved on the second end of the corresponding measuring cylinder 2 and locked by a clamp.

[0038] Each connecting member 12 may include: a connecting column 121, two connecting tubes 122 and two locking mechanisms. A through hole is provided at the center of the connecting column 121, and two connecting tubes 122 are respectively arranged on both sides of the connecting column 121, and both connecting tubes 122 are connected to the through hole. Specifically, each connecting tube 122 is arranged at the through hole on the corresponding side of the connecting column 121, and the diameter of each connecting tube 122 matches the diameter of the through hole.

[0039] Each connecting pipe 122 is inserted into the inside of the corresponding branch pipe 11, and the two locking mechanisms correspond to the two connecting pipes 122 one by one, and each locking mechanism is used to lock the corresponding connecting pipe 122 with the branch pipe 11. Specifically, the two branch pipes 11 to be connected are respectively sleeved on the outside of the corresponding connecting pipe 122, and then locked by the corresponding locking mechanism.

[0040] Preferably, each locking mechanism includes: a protective tube 123, a locking member 124 and a sealing structure. The protective tube 123 is sleeved on the outside of the branch tube 11 corresponding to the connecting tube 122, and the locking member 124 locks the protective tube 123, the branch tube 11 and the connecting tube 122. Specifically, after the branch tube 11 is sleeved on the outside of the connecting tube 122, the protective tube 123 is sleeved on the outside of the branch tube 11 and locked by the locking member 124, so that the protective tube 123, the branch tube 11 and the connecting tube 122 are connected together. The locking member 124 can be a clamp or other device, and this embodiment does not impose any limitation on this.

[0041] The sealing structure is disposed between the branch pipe 11 and the connecting pipe 122 to improve the sealing performance and prevent the liquid from flowing out.

[0042] Preferably, the sealing structure is a sealing gasket or a water-stopping ring. Specifically, the sealing gasket or the water-stopping ring is sleeved on the connecting pipe 122 and contacts the end surface of the branch pipe 11 .

[0043] It can be seen that in this embodiment, the connecting pipe 1 is connected in sequence through a plurality of branch pipes 11 and connecting pieces 12, and the length of the connecting pipe 1 can be adjusted to adapt to pile legs with different spacings, thereby expanding the scope of use.

[0044] Combination Figure 1 The use process of the calibration device is introduced as follows: before operation, open the cover 5 of the first measuring cylinder, add water to the first measuring cylinder, until the second measuring cylinder and the connecting tube 1 are filled with water, and when the water in the first measuring cylinder reaches any position of the scale, stop adding water and tighten the cover 5.

[0045] During calibration, one person holds the first measuring cylinder and places it at the preset position of the pile leg, and the other person holds the second measuring cylinder and places it near the preset position of the adjacent pile leg. By adjusting the position of the second measuring cylinder up and down, the liquid level scale of the second measuring cylinder is made the same as the liquid level scale of the first measuring cylinder. Then, the two people use the marking pen 31 to mark their respective pile legs at the same time. Then, the sensor is installed at the marked position according to actual needs.
