Description

Technical Field

[0001] The invention relates to a sensor fixing device. Background Art

[0002] In model tests of ships and offshore platforms, photospheric positioning is usually used. Through a combination of multiple points, usually three to four points, the position information of the model can be determined. Then the motion time data of the model can be obtained by calculation, and the (angular) velocity and (angular) acceleration in the corresponding six directions can be calculated.

[0003] However, to monitor the acceleration and angle changes of actual ships and offshore platforms, corresponding three-dimensional linear acceleration sensors and angle sensors are required. Ships may encounter uncertain sea conditions during navigation, which may be accompanied by large-scale swaying of the ship. In this case, effective and stable sensor fixation is very important. On the one hand, it can protect the sensor itself, and on the other hand, it can more accurately record the movement and posture of the ship, which is convenient for the crew to judge the status of the ship and assist the crew in making decisions.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 7 As shown, the present invention provides a sensor fixing device, comprising:

[0030] Fixed base 5;

[0031] A second rotating base 4 connected to the top surface of the fixed base 5;

[0032] A rotating two-way connector 3 having one end connected to the second rotating base 4;

[0033] A first rotating base 2, to which the other end of the rotating two-way connector 3 is connected;

[0034] The sensor fixing plate 1 is connected to the top of the first rotating base 2 .

[0035] Here, the device is mainly composed of a sensor fixing plate, a rotating device and a fixed base. The rotating device is composed of three parts, wherein two rotating parts are respectively fixed on the sensor fixing plate and the fixed base plate, and the two are connected in the middle by a rotating two-way connector. The rotating two-way connector can provide angle adjustment in two directions for the sensor 6 to achieve fine-tuning of the sensor installation angle. Through the rotating device, two-way rotation fine-tuning of the acceleration angle sensor can be achieved, and horizontal calibration can be performed in conjunction with a spirit level. The rotating device of the present invention can make the sensor fixing plate rotate around the long side and the short side, and can achieve fine-tuning of the sensor in these two directions. When fixed on a slightly inclined surface, the rotating device can be used to make the measuring direction of the sensor point to the bow or side of the ship.

[0036] This device is suitable for common acceleration sensors and angle sensors on the market, and can be used to fix sensors. The main use scenario is in complex and changeable environments, such as ships and offshore platforms in navigation, where large tilting and shaking of the placement platform is likely to occur. This device can be used to fix acceleration angle sensors during the navigation of ships and offshore platforms, which can provide a more reliable fixing effect and protect the acceleration angle sensor from damage. This device has the advantages of strong fixing ability, various fixing methods, and convenient disassembly and assembly.

[0037] In an embodiment of the sensor fixing device of the present invention, the sensor fixing plate 1 is provided with screw holes for fixing the sensor.

[0038] Here, the sensor fixing plate can provide basic fixation for the sensor, and provides screw holes for fixation at corresponding positions, further fixing the sensor on the fixing device. The sensor fixing plate has screw holes at corresponding positions according to the existing sensor fixing method, and the sensor can be fixed to the sensor fixing plate by screw fixation. For sensors of specific models, additional screw holes can also be opened, which is very convenient and quick. The sensor fixing plate can play a preliminary fixing role for the sensor.

[0039] The sensor fixing plate described in the present invention can conveniently fix the sensor on the entire fixing device according to the original sensor fixing method - usually screw fixing - without the need for additional drilling operations, and has no effect on the fixing method of the sensor itself.

[0040] In one embodiment of the sensor fixing device of the present invention, a level is provided on the sensor fixing plate 1. Preferably, the level is a bubble level.

[0041] Here, the angle of the sensor can be corrected using a simple level on the sensor fixing plate.

[0042] In one embodiment of the sensor fixing device of the present invention, two empty spaces are opened on the side of the sensor fixing plate 1, and the level is placed in the empty spaces.

[0043] Here, there are two empty spaces on the side of the sensor fixing plate, which can be used to place a simple bubble level, which can be used in conjunction with the rotating device to fine-tune and calibrate the installation position of the sensor.

[0044] In one embodiment of the sensor fixing device of the present invention, a magnet is disposed at the bottom of the fixing base 5 .

[0045] Here, a magnet can be installed under the entire fixing base so that the entire fixing device can be fixed on the surface of the object by magnetic attraction. The magnetic fixing base can adsorb the entire fixing device to the metal surface by magnetic force.

[0046] In an embodiment of the sensor fixing device of the present invention, the fixing base plate is surrounded by four extending square plates.

[0047] Here, four extended blocks are designed around the fixed base plate to facilitate welding fixation and further improve the reliability of welding fixation.

[0048] In an embodiment of the sensor fixing device of the present invention, a plurality of screw holes are reserved on the fixing base plate.

[0049] Here, the fixing base plate has a plurality of screw holes reserved, such as four, and the positions of the screw holes and the matching screw diameters can be determined according to the actual fixing situation.

[0050] The fixing base plate of the present invention can be fixed to the surface of the object by screw fixing, magnetic fixing and welding fixing. The three fixing methods can be used in combination, or magnetic fixing can be used alone to fix the sensor conveniently and quickly. The reserved welding position can provide the strongest fixing method without damaging the sensor.

[0051] The fixing device of the present invention can be used to fix common acceleration sensors and angle sensors on the market. It can fix the sensors in complex and changeable environments, such as ships and offshore platforms at sea, where large tilting and shaking of the placement platform may occur. The device can provide three methods of fixing to the surface of the object: screw fixing, magnetic fixing, and welding fixing, providing a more reliable fixing effect and protecting the acceleration and angle sensors from damage.

[0052] In the process of installing the sensor to the fixing device, first install the sensor on the sensor fixing plate 1 according to different models, such as acceleration sensor or angle sensor. Different sensors correspond to different screw holes. Figure 6 and 7 As shown. Then install the first rotating base 2 and the second rotating base 4 on the sensor fixing plate 1 and the fixing base 5 respectively. Finally, connect the upper and lower parts by rotating the two-way connector 3. At this point, the installation of the fixing device is completed.

[0053] like Figure 5As shown in the axonometric diagram of the rotating device, the rotating device is composed of a first rotating base 2, a rotating two-way connector 3 and a second rotating base 4. Combined with the level gauges in two directions on the sensor fixing plate 1, the fixing device can be fine-tuned in two horizontal directions. Through the magnetic base and the reserved screw holes and welding points on the fixing base 5, the entire fixing device together with the sensor can be fixed to the surface of the object to be attached, and can be fixed in combination with magnetic attraction, screws, welding and other methods, with a stronger fixing effect.

[0054] By adopting the above scheme, the fixing device has the following characteristics:

[0055] 1) The fixture parts are simple, the overall installation is relatively convenient, and it is compatible with different sensor types and screw hole positions.

[0056] 2) The fixing device has a built-in rotating device, and a level gauge can be installed in the reserved slot to achieve fine adjustment of the level in two directions.

[0057] 3) The fixing device can be fixed to the surface of the object by screw fixing, magnetic fixing, and welding fixing. There are various fixing methods.

[0058] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0059] Obviously, those skilled in the art can make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if these modifications and variations of the invention fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.
