Description

Technical Field

[0001] This utility model relates to the field of underwater monitoring equipment technology, and in particular to an adjustable underwater sensor fixing device. Background Technology

[0002] In the fields of hydrological monitoring, water quality analysis, or underwater engineering exploration, monitoring sensors need to be precisely deployed at designated underwater locations. To ensure the long-term stability and accuracy of monitoring data, the sensors must be firmly installed on the seabed using fixing devices. Existing underwater fixing devices typically use gravity-based bases sunk to the bottom or pile driving for fixation. However, when the water flow in the deployment environment is fast, or when the bottom sediment is soft mud or sand, the stability of the base relying solely on gravity is poor, and it will sway or even shift under the impact of the water flow, affecting the monitoring accuracy. While the traditional pile driving method provides better fixation, it is complex to construct and difficult to cope with changes in the bottom sediment.

[0003] Furthermore, the existing fixed devices have a single function. The installation height and monitoring posture of the sensors are fixed before or during installation. Once deployed, if the monitoring height or orientation of the sensors needs to be adjusted due to water flow, siltation, or changes in the monitoring target, it cannot be easily adjusted underwater. Operators must retrieve the entire device from the water and reset it, which greatly increases the difficulty of maintenance and operating costs. This cannot meet the requirements of modern underwater monitoring tasks for flexibility and accuracy.

[0004] Therefore, this utility model proposes an adjustable underwater sensor fixing device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of poor structural stability, swaying due to water flow impact, and difficulty in accurately adjusting the height and attitude of the sensor after deployment in the existing adjustable underwater sensor fixing device, this utility model aims to provide an adjustable underwater sensor fixing device with improved structure that can effectively solve the above problems.

[0006] This utility model provides an adjustable underwater sensor fixing device, including: a base, a column disposed on the base, an adjustment mechanism, and a stabilization mechanism.

[0007] The adjustment mechanism includes a guide rail installed on the front side of the column, a sliding sleeve that can slide up and down along the guide rail, a locking bolt threaded to the sliding sleeve, a support plate connected to the front end of the sliding sleeve, a clamping seat welded to the support plate, a universal ball joint wrapped around the top of the clamping seat, an adjustment handle threaded to one side of the clamping seat, and a flange interface welded to the universal ball joint. The flange interface is used to connect the monitoring sensor.

[0008] Furthermore, the stabilizing mechanism includes a counterweight fixedly connected to the bottom of the column and the base, a fixing ring welded to the outer wall of the counterweight, a ring array of holes on the fixing ring, a sinking ring welded to the outer wall of the counterweight and located outside the fixing ring, and a ground nail that can pass through the holes.

[0009] Preferably, the locking bolt is tightened at its end to release from or press against the column, thereby locking and unlocking the sliding sleeve.

[0010] Preferably, the adjusting handle is tightened to drive the clamping seat to clamp the universal ball head, thereby locking the angle of the universal ball head.

[0011] Preferably, the flange interface is used for quick connection of the monitoring sensor.

[0012] Preferably, the counterweight has a high density to lower the center of gravity of the fixing device.

[0013] Preferably, the settling ring has a certain density and is used to increase the contact area with the sediment at the bottom of the water.

[0014] Preferably, the bottom of the ground nail is sharp, for insertion into the mud and sand at the bottom of the water.

[0015] Preferably, the ground stake has an overall inverted U shape.

[0016] In summary, this utility model has the following beneficial effects: 1. In this utility model, by setting up a stabilizing mechanism consisting of a counterweight, a fixing ring, a ground nail, and a settling ring working together, the problem of poor stability of underwater fixing devices in the prior art under muddy bottom and water flow impact environments, which can cause swaying and displacement, is solved. This achieves multiple stabilizations by lowering the center of gravity, physical anchoring, and increasing the contact area, making the device reliable and strong in impact resistance.

[0017] 2. In this utility model, by setting an adjustment mechanism consisting of a guide rail, a sliding sleeve, a universal ball joint and a clamping seat, the problem of fixed height and difficulty in accurately adjusting the monitoring posture of underwater sensors after installation in the prior art is solved. It can conveniently adjust the height in the vertical direction and freely adjust the monitoring orientation in multiple angles in space, thus realizing the accurate deployment of the sensor.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides an adjustable underwater sensor fixing device, including a base 1, a column 2 mounted on the base 1, an adjustment mechanism 3, and a stabilizing mechanism 4. The adjustment mechanism 3 is installed on the front side of the column 2, and the stabilizing mechanism 4 is located at the bottom of the base 1. The column 2 provides vertical support and a mounting base for the adjustment mechanism 3. The base 1 and the bottom of the column 2 are fixedly connected, and the base 1 and the stabilizing mechanism 4 together form the load-bearing and stabilizing foundation of this device. The adjustment mechanism 3 is used to realize the height adjustment and spatial attitude rotation of the monitoring sensor 5. The stabilizing mechanism 4 ensures that the fixing device can still stand stably under the impact of water flow through multiple methods such as counterweight, anchoring, and increasing the contact area. The monitoring sensor 5 is detachably mounted on the fixing device through the adjustment mechanism 3. The entire device is anchored in the mud and sand at the bottom of the water through the stabilizing mechanism 4, and the monitoring sensor 5 is precisely positioned through the adjustment mechanism 3.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3The adjustment mechanism 3 enables height and attitude adjustment of the monitoring sensor 5. The adjustment mechanism 3 includes a guide rail 301 mounted on the front side of the column 2, a sliding sleeve 302 that can slide up and down along the guide rail 301, a locking bolt 303 threaded to the sliding sleeve 302, a support plate 304 fixedly connected to the front end of the sliding sleeve 302, a clamping seat 305 welded to the support plate 304, a universal ball joint 306 wrapped around the top of the clamping seat 305, an adjustment handle 307 threaded to one side of the clamping seat 305, and a flange interface 308 welded to the universal ball joint 306. When the height of the monitoring sensor 5 needs to be adjusted, the locking bolt 303 is rotated, causing the end of the locking bolt 303 to leave the column 2. At this time, the sliding sleeve 302 is unlocked and... The sliding sleeve 302 can slide up and down on the guide rail 301. After the sliding sleeve 302 is adjusted to the appropriate height, the locking bolt 303 is rotated in the opposite direction to make the end of the locking bolt 303 press against the column 2, thereby completing the height fixation of the sliding sleeve 302. The support plate 304 provides front-end support for the clamping seat 305. The universal ball head 306 can rotate freely in space within the clamping seat 305. When it is necessary to adjust the orientation of the monitoring sensor 5, rotate the universal ball head 306. After adjusting the universal ball head 306 to the required angle, tighten the adjusting handle 307 on one side of the clamping seat 305 to clamp and lock the universal ball head 306. The flange interface 308 is used for quick connection and fixation of the monitoring sensor 5. The monitoring sensor 5 is installed on the universal ball head 306 through the flange interface 308.

[0026] In a preferred embodiment, the locking bolt 303 is tightened at its end to disengage from or press against the column 2, thereby locking and unlocking the sliding sleeve 302.

[0027] In a preferred embodiment, the adjusting handle 307 is tightened to drive the clamping seat 305 to clamp the universal ball head 306, thereby locking the angle of the universal ball head 306.

[0028] In a preferred embodiment, flange interface 308 is used for quick connection of monitoring sensor 5.

[0029] As a preferred embodiment, the counterweight 401 has a high density to lower the center of gravity of the fixing device.

[0030] As a preferred embodiment, the settling ring 404 has a certain density and is used to increase the contact area with the sediment at the bottom of the water.

[0031] As a preferred embodiment, the bottom of the ground nail 405 is sharp and designed for insertion into the mud and sand at the bottom of the water.

[0032] As a further definition of the aforementioned ground stake 405, the ground stake 405 is in the shape of an inverted U.

[0033] Working principle: Before precise underwater operations are required, the fixing device is placed in a suitable underwater position. The counterweight 401, which is fixedly connected to the bottom of the column 2 and the base 1 in the stabilizing mechanism 4, has a high density and is used to lower the center of gravity of the fixing device, making the whole device more stable. Then, the ground nails 405 are passed through the insertion holes 403 arranged in a ring on the fixing ring 402 in sequence. The bottom of the ground nails 405 is sharp and is used to insert into the mud and sand at the bottom of the water. The ground nails 405 are in an inverted U shape, which can fix the fixing ring 402 well underwater. The fixing ring 402 is welded to the outer wall of the counterweight 401. The stabilizing ring 404, which is welded to the outer wall of the counterweight 401 and is located outside the fixing ring 402, also has a certain density and is used to increase the contact area with the mud and sand at the bottom of the water. The stabilizing ring 404 reduces the shaking caused by the water flow impact and improves the overall stability of the fixing device. After the fixing device is stably erected, the position and orientation of the monitoring sensor 5 are adjusted. The adjustment mechanism 3 is installed on the front side of the column 2, and the column 2 is equipped with a guide rail 301. When it is necessary to adjust the height of the monitoring sensor 5, the locking bolt 303 threaded to the sliding sleeve 302 is rotated, so that the end of the locking bolt 303 moves away from the column 2. The sliding sleeve 302, which can slide up and down along the guide rail 301, can then slide up and down on the guide rail 301. After the sliding sleeve 302 is adjusted to the appropriate height, the locking bolt 303 is rotated in the opposite direction, so that the end of the locking bolt 303 presses against the column 2, thus fixing the height of the sliding sleeve 302. When the orientation is adjusted, the flange interface 308 welded to the universal ball head 306 is used for quick connection and fixation of the monitoring sensor 5. The universal ball head 306 is wrapped around the top of the clamping seat 305 and can rotate freely in space within the clamping seat 305. The orientation of the monitoring sensor 5 is adjusted by rotating the universal ball head 306. After adjusting to the required angle, the adjusting handle 307 threaded to one side of the clamping seat 305 is tightened. The adjusting handle 307 drives the clamping seat 305 to clamp the universal ball head 306, thereby locking the universal ball head 306. The clamping seat 305 is welded to the support plate 304. The support plate 304 is connected to the front end of the sliding sleeve 302 to form a stable support. Through the multiple stabilizing designs of the stabilizing mechanism 4, including the lowering of the center of gravity by the counterweight 401, the anchoring effect of the ground nail 405, and the anti-swaying effect of the stabilizing ring 404, this utility model effectively solves the problem of unstable swaying of the fixed device underwater due to the impact of water flow in the prior art. At the same time, through the sliding cooperation between the guide rail 301 and the sliding sleeve 302 in the adjusting mechanism 3, and the rotational locking cooperation between the universal ball head 306 and the clamping seat 305, the height and attitude of the monitoring sensor 5 can be accurately and conveniently adjusted.
