Description

Technical Field

[0001] This invention relates to the field of tilt sensor technology, and more specifically, to a tilt sensor with a large tilt angle and small size based on a femtosecond grating. Background Technology

[0002] Tilt sensors with large tilt angles and small dimensions based on femtosecond gratings are used to measure tilt angles, thereby preventing objects from being tilted. However, since the objects to be measured vary, the installation positions also vary. Some need to be clamped to a pole, while others need to be placed on a flat surface, and so on. Existing tilt sensors are mostly installed in a fixed manner, which cannot be installed according to actual needs. This may require additional installation equipment to install the tilt sensor, which increases the complexity of installation and is not convenient. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a tilt sensor with a large tilt angle and small size based on a femtosecond grating, which has the advantage of being able to be installed in different scenarios.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tilt sensor with a large tilt angle and small size based on a femtosecond grating, comprising a mounting plate, a gear movably connected to the center of the inner cavity of the mounting plate, fixing plates fixedly connected to the left and right ends of the mounting plate, a spring fixedly connected to the side of the fixing plate near the center of the mounting plate, a moving rod fixedly connected to the side of the spring away from the fixing plate, a sliding rod fixedly connected to the rear side of the moving rod away from the gear, a rack fixedly connected to the side of the moving rod near the gear, a guide rod fixedly connected to the side of the moving rod near the fixing plate, a connecting rod fixedly connected to the bottom end of the moving rod, a base fixedly connected to the bottom end of the connecting rod, threaded plates fixedly connected to the front and rear sides of the base, and a support block fixedly connected to the side of the base away from the mounting plate.

[0005] As a preferred embodiment of the present invention, the top end of the mounting plate is fixedly connected to the tilt sensor body, the top end of the tilt sensor body is fixedly connected to the water-cooled plate, and the top end of the water-cooled plate is fixedly connected to the sealing sleeve.

[0006] As a preferred embodiment of the present invention, the moving rod meshes with a gear via a rack, and the guide rod is located in the inner cavity of the spring and passes through the circular hole in the middle of the fixed plate.

[0007] As a preferred embodiment of the present invention, the support block is conical, and the threaded plate has a threaded hole in the middle.

[0008] As a preferred embodiment of the present invention, the mounting plate has sliding grooves on both the front and rear sides of its inner cavity, and the moving rod is slidably connected to the inner cavity of the sliding groove via a sliding rod.

[0009] As a preferred embodiment of the present invention, rectangular holes are provided on both the front and rear sides of the bottom center of the mounting plate, and the connecting rod passes through the rectangular holes and is fixedly connected to the base.

[0010] As a preferred embodiment of the present invention, a heat-conducting sheet is fitted into the inner cavity of the sealing sleeve, and the bottom end of the heat-conducting sheet is located in the inner cavity of the water-cooling plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. This invention involves moving one of the bases, which in turn moves a movable rod. Through the meshing of a rack and pinion, the gear rotates, causing the other movable rod to move, which in turn moves the other base. The rod to be installed is then positioned between the two bases, where a spring clamps it in place, thus completing the installation of the tilt sensor body. A support block allows the tilt sensor body to be placed horizontally, and a threaded plate secures it to a wall. This invention offers multiple installation methods, allowing users to choose the installation method according to their needs, greatly improving the practicality and convenience of the device.

[0013] 2. This invention addresses the issue that the tilt sensor body generates a significant amount of heat during prolonged use. The heat is absorbed by the coolant within the water-cooled plate cavity and then transferred to the air via a heat-conducting sheet. This efficient heat dissipation prevents the tilt sensor body from generating excessive heat during extended operation, thus ensuring optimal sensing performance. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the present invention provides a tilt sensor with a large tilt angle and small size based on a femtosecond grating, including a mounting plate 1. A gear 2 is movably connected to the center of the inner cavity of the mounting plate 1. Fixing plates 3 are fixedly connected to the left and right ends of the mounting plate 1. A spring 4 is fixedly connected to the side of the fixing plate 3 near the center of the mounting plate 1. A moving rod 5 is fixedly connected to the side of the spring 4 away from the fixing plate 3. A sliding rod 6 is fixedly connected to the rear side of the moving rod 5 away from the gear 2. A rack 7 is fixedly connected to the side of the moving rod 5 near the gear 2. A guide rod 8 is fixedly connected to the side of the moving rod 5 near the fixing plate 3. A connecting rod 9 is fixedly connected to the bottom end of the moving rod 5. A base 10 is fixedly connected to the bottom end of the connecting rod 9. Threaded plates 11 are fixedly connected to the front and rear sides of the base 10. A support block 13 is fixedly connected to the side of the base 10 away from the mounting plate 1.

[0022] By pulling one of the bases 10, the movement of the base 10 drives the moving rod 5 to move. Through the meshing of the rack 7 and the gear 2, the gear 2 is driven to rotate. The rotation of the gear 2 then drives the other moving rod 5 to move, thereby driving the other base 10 to move. The rod to be installed is then placed between the two bases 10. The force provided by the spring 4 allows the two bases 10 to clamp the rod, thus completing the installation of the tilt sensor body 14. The support block 13 allows the tilt sensor body 14 to be placed horizontally, and the threaded plate 11 allows the tilt sensor body 14 to be fixedly installed on the wall. It has multiple installation methods, allowing users to rotate the installation method according to actual needs, greatly improving the practicality and convenience of this device.

[0023] The top of the mounting plate 1 is fixedly connected to the tilt sensor body 14, the top of the tilt sensor body 14 is fixedly connected to the water cooling plate 15, and the top of the water cooling plate 15 is fixedly connected to the sealing sleeve 16.

[0024] During prolonged use, the tilt sensor body 14 generates a significant amount of heat. The coolant inside the water-cooling plate 15 absorbs this heat, and the heat absorbed by the coolant is then transferred to the air via the heat-conducting plate 17. This efficient heat dissipation prevents the tilt sensor body 14 from generating excessive heat during prolonged operation, thus ensuring that the sensing performance is not affected.

[0025] Among them, the moving rod 5 meshes with the gear 2 through the rack 7, and the guide rod 8 is located in the inner cavity of the spring 4 and passes through the round hole in the middle of the fixed plate 3;

[0026] The movable rod 5 meshes with the gear 2 through the rack 7, so that when one of the movable rods 5 moves, it can drive the gear 2 to rotate, thereby driving the other base 10 to move. Then, the guide rod 8 is located in the inner cavity of the spring 4 and passes through the round hole in the middle of the fixed plate 3, thereby positioning and guiding the spring 4, thus preventing the spring 4 from shifting during deformation.

[0027] Among them, the support block 13 is conical, and the threaded plate 11 has a threaded hole in the middle;

[0028] The support block 13 is tapered, which increases the contact area with the placement plane, thus allowing the tilt sensor body 14 to be placed more stably and preventing it from tipping over. The threaded plate 11 has a threaded hole in the middle, which allows the operator to install the threaded plate 11 using bolts.

[0029] The mounting plate 1 has sliding grooves 12 on both the front and rear sides of its inner cavity, and the moving rod 5 is slidably connected to the inner cavity of the sliding groove 12 via the sliding rod 6.

[0030] The movable rod 5 is slidably connected to the inner cavity of the slide groove 12 via the slide rod 6, thereby positioning and guiding the movable rod 5 through the slide groove 12, thus preventing the movable rod 5 from deviating during the movement process and enhancing the stability of the movable rod 5 during movement.

[0031] The mounting plate 1 has rectangular holes on both the front and rear sides at the bottom center, and the connecting rod 9 passes through the rectangular holes and is fixedly connected to the base 10.

[0032] The connecting rod 9 is fixedly connected to the base 10 through the rectangular hole, so that the connecting rod 9 can drive the base 10 to move without being blocked by the mounting plate 1, thus avoiding the situation where it cannot drive the base 10 to move smoothly.

[0033] The inner cavity of the sealing sleeve 16 is fitted with a heat-conducting plate 17, and the bottom end of the heat-conducting plate 17 is located in the inner cavity of the water-cooling plate 15.

[0034] The heat-conducting sheet 17 is attached to the inner cavity of the sealing sleeve 16, thereby sealing the space between the heat-conducting sheet 17 and the mounting plate 1, preventing water from leaking out from the heat-conducting sheet 17. The bottom end of the heat-conducting sheet 17 is located in the inner cavity of the water-cooling plate 15, thereby allowing the heat from the inner cavity of the water-cooling plate 15 to be transferred to the air.

[0035] The working principle and usage process of the present invention: The tilt sensor body 14 is installed by screwing the bolt into the inner cavity of the threaded plate 11, or by contacting the bottom of the base 10 and the support block 13 with the horizontal surface, so that the tilt sensor body 14 is placed directly on the horizontal surface.

[0036] Alternatively, one of the bases 10 can be pulled to move it, and then the connecting rod 9 can drive the moving rod 5 to move along the axis of the slide groove 12. Then, the rack 7 meshes with the gear 2, thereby driving the gear 2 to rotate. The rotation of the gear 2 can drive the other moving rod 5 to move, thus realizing the movement of the other support block 13. Then, the rod to be clamped is placed between the two bases 10. Then, the bases 10 are released, and the force provided by the spring 4 drives the two support blocks 13 to clamp the rod.

[0037] The tilt sensor body 14 is cooled by the water-cooled plate 15. Then, the coolant inside the water-cooled plate 15 is cooled by the heat-conducting sheet 17. The heat is then transferred to the air by the heat-conducting sheet 17 for rapid heat dissipation.
