[0002] A hydrostatic level is a specialized precision instrument used to measure the relative elevation changes between various measuring points on a foundation or structure. It is mainly used for measuring uneven settlement between various measuring points on large structures such as hydroelectric power plants, dams, high-rise buildings, nuclear power plants, and rock masses in water conservancy projects.

[0003] In the prior art, the utility model patent with authorization announcement number CN219434050U discloses a laser rangefinder-type static level, which infers water level changes by measuring the displacement of a reflector along the vertical direction using a laser rangefinder. This solves the problems of poor measurement accuracy and small measuring range of existing static levels. However, the disassembly of the laser rangefinder on the container is not convenient, which makes it difficult to disassemble when the laser rangefinder malfunctions or is damaged and needs to be disassembled for repair or replacement. This affects the convenience and efficiency of disassembly and maintenance of the laser rangefinder on the static level. Therefore, a laser static level that is easy to maintain is proposed.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-4The laser static level, which is easy to maintain, includes a level housing 100, an outer cover 201, a limiting block 203, and a blocking block 206. A float 102 is slidably connected inside the level housing 100, and a reflector 103 is fixedly connected to the top of the float 102. A laser ranging assembly 200 is fixedly connected to the bottom of the outer cover 201, and the laser ranging assembly 200 extends from the top of the level housing 100 to the inner cavity of the level housing 100. The limiting block 203 is fixedly connected to the side wall of the outer cover 201, and an arc-shaped through groove 204 is formed on the end face of the limiting block 203. Furthermore, the end of the arc-shaped through groove 204 is concave downwards. A second elastic tension member 207 is fixedly connected between the blocking block 206 and the top of the level instrument housing 100. A convex ring 202 is fixedly connected to the middle of the top of the level instrument housing 100, and a sealing gasket is fixedly connected to the top of the convex ring 202. The outer diameter of the convex ring 202 matches the inner diameter of the outer cover 201. During specific assembly, since the laser ranging assembly 200 is fixedly assembled at the bottom of the outer cover 201, after inserting the laser ranging assembly 200 from the top of the level instrument housing 100, the outer cover 201 blocks... At the top of the level instrument housing 100, and at the position of the end of the arc-shaped groove 204 on the limiting block 203 fixed to the side wall of the outer cover 201, which corresponds to the position of the second elastic tension member 207 fixed on the level instrument housing 100, the outer cover 201 is manually rotated. This causes the end of the arc-shaped groove 204 to press against the blocking block 206, which in turn causes the second elastic tension member 207 to stretch and deform. As a result, the blocking block 206 moves with the rotation of the limiting block 203 to the recessed position at the end of the arc-shaped groove 204. At this time, the blocking block 206 descends and engages with the recessed position at the end of the arc-shaped groove 204. The limiting block 203 acts as a limiting and blocking element, thus ensuring the stable installation of the outer cover 201 and the laser rangefinder assembly 200 on the level housing 100. Similarly, during disassembly, simply pull up the blocking block 206 to release the rotational limitation on the outer cover 201, and then rotate the outer cover 201 in the opposite direction to disengage the blocking block 206 from the arc-shaped through groove 204. This releases the vertical limitation on the outer cover 201, allowing the outer cover 201 and the laser rangefinder assembly 200 to be directly pulled out, thus enabling the laser rangefinder assembly 200 to be easily and quickly disassembled and maintained.

[0030] Furthermore, a water inlet 101 is fixedly connected to the bottom of the level instrument housing 100. The water inlet 101 is used to connect the inner cavity of the level instrument housing 100 with the outside. An exhaust hole 104 is provided on the top of the level instrument housing 100. A sealing component is provided at the top of the level instrument housing 100 corresponding to the exhaust hole 104. The water inlet 101 facilitates the entry of liquid to drive the float 102 to float, thereby cooperating with the laser ranging assembly 200 to monitor sedimentation. The exhaust hole 104 can assist in the discharge of gas when the float 102 moves upward. The sealing component provides a shielding and protection function for the exhaust hole 104, preventing dust and other debris from entering the interior of the level instrument housing 100 and causing pollution.

[0031] The sealing assembly includes an exhaust pipe 105, a sealing plug 106, and multiple first elastic tension members 107. The exhaust pipe 105 is fixedly connected to the exhaust hole 104 at the top of the level housing 100. The exhaust pipe 105 has a convex shape with a narrow top and a wide bottom. The exhaust pipe 105 is located above the exhaust pipe 105, and the bottom of the sealing plug 106 is slidably connected to the inside of the exhaust pipe 105. The multiple first elastic tension members 107 are fixedly arranged at intervals between the sealing plug 106 and the exhaust pipe 105. When there is gas inside the level instrument housing 100 that needs to be discharged from the exhaust port 104, the air pressure pushes the sealing plug 106 upward. At this time, the first elastic tension member 107 undergoes elastic deformation. After the gas is discharged, the first elastic tension member 107 provides a downward pulling force for the sealing plug 106, so that the sealing plug 106 blocks the port of the exhaust pipe 105. In other embodiments, the first elastic tension member 107 can also be a common telescopic rod to connect the sealing plug 106 and the exhaust pipe 105.

[0032] Furthermore, the first elastic tension member 107 includes a T-shaped rod 171, a sleeve 172, and an elastic compression spring 173. The bottom end of the T-shaped rod 171 is fixed to the protruding position on the side wall of the exhaust pipe 105. The sleeve 172 is slidably sleeved on the outside of the T-shaped rod 171, and the top end of the sleeve 172 is fixed to the bottom of the sealing plug 106. The two ends of the elastic compression spring 173 are respectively fixed to the top of the T-shaped rod 171 and the bottom of the inner side of the sleeve 172. In addition, the composition of the second elastic tension member 207 is the same as that of the first elastic tension member 107, and the sleeve 172 located inside the second elastic tension member 207... The T-shaped rod 171, which is fixedly connected to the bottom end of the blocking block 206 and located inside the second elastic tension member 207, is fixedly connected to the top end of the level instrument housing 100. The diameter of the sleeve 172 located inside the second elastic tension member 207 is smaller than the width of the arc through groove 204. The sleeve 172 provides elastic tension between the T-shaped rod 171 and the elastic compression spring 173. After the length between the elastic compression spring 173 and the T-shaped rod 171 increases, an elastic tension can be generated between them, thus satisfying the need for the sealing plug 106 and the blocking block 206 to move automatically downward.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
