Description

Technical Field

[0001] This application relates to the field of hydrostatic leveling instruments, and more specifically, to a fiber optic grating hydrostatic leveling instrument. Background Technology

[0002] With the development of the times and the progress of science and technology, static levels are now needed to measure the settlement changes of civil engineering structures such as high-speed railways, bridges, dams, tunnels and large buildings. Therefore, static levels are widely used in the market. Fiber grating static levels are one type of static level. They are not only sensitive to physical quantities such as strain, but also to temperature factors. Currently, fiber grating static levels are usually used in pairs, connected by a connecting pipe.

[0003] Chinese patent CN211147648UU discloses a fiber optic grating static level, equipped with a protective block for the fiber optic grating static level housing. The design of the protective block can effectively prevent the fiber optic grating static level housing from being damaged during use, solving the problem that existing fiber optic grating static level housings often cannot be used normally when not in use due to damage to the housing.

[0004] Based on the above technical solution, the applicant believes that although the protective block of the fiber Bragg grating static level can provide partial protection for the housing of the fiber Bragg grating static level when it is not in use, the upper part of the housing is still exposed to the outside. Therefore, the protection of the housing is not comprehensive, and the upper part of the housing is still likely to be damaged when it is not in use, resulting in the problem that the static level housing cannot be used normally. Therefore, we propose a fiber Bragg grating static level. Utility Model Content

[0005] To address the aforementioned problems, this application provides a fiber optic grating hydrostatic level, employing the following technical solution:

[0006] A fiber optic grating static level includes a main module and a protective module. The main module includes a base with placement slots on both sides of the top of the base. A leveling component is disposed inside each of the two placement slots. A connecting slot is formed on the top of the base, communicating with the two placement slots. A connecting pipe connects the two leveling components, located inside the connecting slot. The protective module includes a vertical rod fixedly connected to the top of the base, with a top plate fixedly connected to the top of the vertical rod. Two opening / closing components are disposed between the top of the base and the bottom of the top plate. Each of the two opening / closing components has two protective half-covers, with four protective half-covers located outside the two leveling components. A self-locking component is provided on the top of the base, and both opening / closing components are connected to the self-locking component.

[0007] Furthermore, the opening and closing assembly includes two rotating rods that are rotatably connected between the top of the placement seat and the bottom of the top plate. The outer surfaces of the two rotating rods are respectively fixedly connected to the sleeve blocks, and the two protective half covers are respectively connected to the two sleeve blocks. A worm gear block is fixedly connected to the lower part of the outer surface of one of the rotating rods.

[0008] By adopting the above technical solution, the protective half-cover can be rotated, thereby facilitating the protection of the leveling components.

[0009] Furthermore, the opening and closing assembly also includes two gears respectively connected to the outer surfaces of the two rotating rods, and the outer surfaces of the two gears mesh with each other.

[0010] By adopting the above technical solution, the two protective half-covers can rotate in opposite directions, which facilitates synchronous opening and closing.

[0011] Furthermore, the self-locking assembly includes two mounting seats that are fixedly connected to the top of the placement seat. A worm gear is rotatably connected between adjacent sides of the two mounting seats. One end of the worm gear passes through one of the mounting seats and is fixedly connected to a throttle. The worm gear meshes with a worm wheel block.

[0012] By adopting the above technical solution, the two opening and closing components can be driven synchronously, thereby opening all four protective half-covers at the same time, which makes it easier for staff to retrieve the leveling components for use.

[0013] Furthermore, the leveling assembly includes a level housing disposed at the bottom of the inner wall of one of the placement slots and connected to one end of a connecting pipe. The interior of the level housing is filled with a circulating antifreeze. A float ball is disposed inside the level housing and on the circulating antifreeze. A displacement indicator is connected to the top of the level housing. A measuring rod is connected to the outer surface of the float ball. The measuring rod extends out of the exterior of one of the level housings and passes through the displacement indicator.

[0014] By adopting the above technical solution, the overall height difference can be measured by observing the height of the measuring rod by having a floating ball float on the antifreeze.

[0015] Furthermore, the leveling component also includes a mounting groove formed at the bottom of the inner wall of one of the placement slots, a magnetic block is fixedly connected to the bottom of the inner wall of the mounting groove, and a metal block is fixedly connected to the bottom of the level housing, the metal block being movably engaged inside the mounting groove and magnetically connected to the magnetic block.

[0016] By adopting the above technical solution, the housing of the level instrument placed inside the placement slot can be fixed to prevent the housing of the level instrument from shaking.

[0017] Furthermore, the main module also includes two rubber clips respectively disposed inside the two placement slots, the rubber clips being in contact with the outer surface of the level instrument housing.

[0018] By adopting the above technical solution, the housing of the level instrument is further limited and fixed, thereby improving the stability of the level instrument housing.

[0019] Furthermore, the placement base also includes four handles respectively connected to the front and rear faces of the placement base, and four casters are fixedly installed on the bottom of the placement base.

[0020] By adopting the above technical solution, this level instrument is easy to move and use.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] (1) In this application, the worm gear, worm wheel block, two gears and four protective half covers are used to make the four protective half covers close in pairs when the worm gear is rotated, and cover the outer surface of the two leveling components to protect them, thereby preventing the two leveling components from having any structure exposed to the outside and preventing the two leveling components from being damaged by impact.

[0023] (2) By combining the magnetic blocks, mounting grooves and rubber clips, the level instrument housing can be limited and fixed after being placed in the placement groove, thereby preventing the level instrument housing from shaking and improving the stability of the level components when they are placed.

[0024] (3) The combination of four handles and four casters makes this level easy to move and easy to carry when encountering stairs, making it convenient for users to use. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] Please see Figure 1-5 A fiber optic grating static level includes a main module 100 and a protective module 200. The main module 100 includes a base 110, with placement slots 120 on both sides of the top of the base 110. A leveling component 130 is respectively installed inside each of the two placement slots 120. A connecting slot 140 is provided on the top of the base 110, communicating with the two placement slots 120. A connecting pipe 150 connects the two leveling components 130, and the connecting pipe 150 is located inside the connecting slot 140. The protective module 200... The protective module 200 includes a vertical rod 210 fixedly connected to the top of the placement base 110. A top plate 220 is fixedly connected to the top of the vertical rod 210. Two opening and closing components 230 are provided between the top of the placement base 110 and the bottom of the top plate 220. Two protective half covers 240 are provided on each of the two opening and closing components 230. The four protective half covers 240 are located outside the two leveling components 130 respectively. A self-locking component 250 is provided on the top of the placement base 110. Both opening and closing components 230 are connected to the self-locking component 250.

[0038] During use, the operator removes the two leveling components 130 and the connecting pipe 150, places the two leveling components 130 in the designated position for measuring the height difference, and then places the two leveling components 130 into the two placement slots 120 respectively, and the connecting pipe 150 into the connecting slot 140. The operator then rotates the self-locking component 250, which in turn drives the two opening and closing components 230. The two opening and closing components 230 will then drive the four protective half-covers 240 to rotate in opposite directions, so that the four protective half-covers 240 close in pairs and cover the outside of the two leveling components 130, thus providing comprehensive protection for the two leveling components 130 and preventing them from being damaged by collisions when idle.

[0039] Please see Figure 2-5The opening and closing assembly 230 includes two rotating rods 231 rotatably connected between the top of the placement base 110 and the bottom of the top plate 220. The outer surfaces of the two rotating rods 231 are respectively fixedly connected to the sleeve blocks 232. Two protective half covers 240 are respectively connected to the two sleeve blocks 232. The lower part of the outer surface of one of the rotating rods 231 is fixedly connected to a worm gear block 233. The opening and closing assembly 230 also includes two gears 234 respectively connected to the outer surfaces of the two rotating rods 231. The outer surfaces of the two gears 234 mesh with each other. The self-locking assembly 250 includes two mounting bases 251 fixedly connected to the top of the placement base 110. A worm gear 252 is rotatably connected between adjacent sides of the two mounting bases 251. One end of the worm gear 252 passes through one of the mounting bases 251 and is fixedly connected to a handle 253. The worm gear 252 meshes with the worm gear block 233.

[0040] By rotating the worm gear 252 through the throttle 253, the worm gear 252 will drive one of the rotating rods 231 through the worm wheel block 233. Through the meshing of the two gears 234, the two rotating rods 231 rotate in opposite directions, causing the two protective half-covers 240 to move closer to each other and close. This allows the four protective half-covers 240 to close in pairs and cover the outside of the two leveling components 130, thus providing comprehensive protection for the two leveling components 130 and preventing the two leveling components 130 from being damaged by collisions when idle.

[0041] Please see Figure 1-5 The leveling assembly 130 includes a level housing 131 disposed at the bottom of the inner wall of one of the placement slots 120 and connected to one end of a connecting pipe 150. An antifreeze fluid 132 is disposed inside the level housing 131. A float ball 133 is disposed inside the level housing 131 and above the antifreeze fluid 132. A displacement indicator 134 is connected to the top of the level housing 131. A measuring rod 135 is connected to the outer surface of the float ball 133. The measuring rod 135 extends out of the outer side of one of the level housings 131 and passes through the displacement indicator 134. The leveling assembly 130 also includes a level housing 131 formed in the inner wall of one of the placement slots 120. The bottom of the mounting groove 136 has a magnetic block 137 fixedly connected to the bottom of the inner wall of the mounting groove 136. The bottom of the level housing 131 has a metal block 138 fixedly connected to it. The metal block 138 is movably engaged inside the mounting groove 136 and magnetically connected to the magnetic block 137. The main module 100 also includes two rubber clips 160 respectively disposed inside the two placement slots 120. The rubber clips 160 are in contact with the outer surface of the level housing 131. The placement seat 110 also includes four handles 170 respectively connected to the front and rear faces of the placement seat 110. Four casters 180 are fixedly installed on the bottom of the placement seat 110.

[0042] Two level instrument housings 131 are placed inside two placement slots 120 respectively. At the same time, magnetic blocks 137 are inserted into mounting slots 136 and magnetically connected to metal blocks 138. Two rubber clips 160 limit the movement of the two level instrument housings 131, thereby fixing the two level instrument housings 131 and preventing them from shaking. The four casters 180 make the level instrument easy to move. The four handles 170 make the level instrument easy to carry when encountering stairs.

[0043] The implementation principle of this application embodiment is as follows: During use, the operator removes the two level instrument housings 131 and the connecting pipe 150, places the two level components 130 in the designated position, and measures the height difference by observing the height position of the measuring rod 135. After use, the two level instrument housings 131 are placed inside the two placement slots 120 respectively. The two rubber clips 160 limit the two level instrument housings 131 respectively. At the same time, the magnetic block 137 is inserted into the mounting circular slot 136 and magnetically connected to the metal block 138, thereby completing the fixation of the two level instrument housings 131 and preventing the two level instrument housings 131 from shaking, making the two level components 130 very stable. The connecting pipe 150 is placed inside the connecting slot 140. Then, the operator rotates the worm gear 252 by turning the handle 253. The worm gear 252 will pass through the worm wheel block. The transmission 233 drives one of the rotating rods 231, which, through the meshing of two gears 234, causes the two rotating rods 231 to rotate in opposite directions, driving two of the protective half-covers 240 to move closer together and close. This allows the four protective half-covers 240 to close in pairs, covering the two leveling components 130, thus providing comprehensive protection for the two leveling components 130 and preventing them from being damaged by collisions when idle. Due to the self-locking property of the worm gear 252 and the worm wheel block 233, the four protective half-covers 240 will not open when the worm gear 252 is not rotated. Similarly, rotating the worm gear 252 in the opposite direction will open the four protective half-covers 240, making it easy to retrieve the leveling components 130. The four moving wheels 180 make the level easy to move, and the four handles 170 make it easy to carry when encountering stairs.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
