Description

Technical Field

[0001] This utility model relates to the field of water level measurement technology, specifically a protective bracket for a portable hydraulic water level measuring instrument. Background Technology

[0002] In water conservancy projects, water level measurement is a core part of water resource management, flood control and drought relief, and hydrological monitoring. Portable water level measuring instruments are widely used for real-time water level monitoring in rivers, lakes, reservoirs, irrigation areas and other scenarios due to their high mobility and ease of operation. These devices usually need to be used with a support to ensure stability, safety and data accuracy during the measurement process. However, the protective support of the measuring instrument makes it difficult to adjust the position of the measuring instrument, and measuring the water level at the same location in isolation will result in incomplete measurement results.

[0003] For example, CN115824159A discloses a protective mechanism for a building level measuring instrument, including a level measuring instrument, a support, and a conical bracket. A protective outer cylinder is snapped onto the outside of the level measuring instrument. A connecting mechanism for use with the support is provided at the bottom of the inner side of the protective outer cylinder. Side protection mechanisms for use with the level measuring instrument are provided on both sides of the inner side of the protective outer cylinder. A rubber pressure pad is provided at the top of the level measuring instrument. An upper protection mechanism for use with the rubber pressure pad is provided on the rubber pressure pad. A fixed frame plate is connected to the top of the outer side of the protective outer cylinder. A U-shaped lifting handle is inserted into the fixed frame plate. Guide blocks are fixedly connected to the bottom of both ends of the lifting handle. Guide grooves for use with the guide blocks are opened inside the side walls of the fixed frame plate.

[0004] However, there are shortcomings: due to the limitations of the adjustment mechanism, the protective bracket of the measuring instrument is not able to flexibly drive the measuring instrument to make all-round position adjustments. If the measurement is only carried out for the water level at the same fixed position, it is easy to lead to a single monitoring perspective, so that the water level data obtained lacks the comprehensiveness and representativeness of the spatial dimension, and it is difficult to accurately reflect the real hydrological conditions of the monitoring area. Utility Model Content

[0005] The purpose of this utility model is to provide a protective bracket for a portable hydraulic water level measuring instrument, so as to solve the problem mentioned in the background art that the protective bracket of the measuring instrument is difficult to drive the measuring instrument to adjust its position, and that the measurement results are not comprehensive when measuring the water level at the same position only.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a protective bracket for a portable hydraulic water level measuring instrument, comprising a base plate, a lifting mechanism slidably disposed on the upper side of the base plate, the lifting mechanism comprising a fixed column three slidably disposed on the upper side of the bottom end, a connecting column one fixedly connected to the top of the fixed column three, a cylinder fixedly connected to the top of the connecting column one, a telescopic column slidably connected to the upper end of the cylinder, a connecting column two fixedly connected to the top of the telescopic column, a connecting shaft two rotatably connected to the inner cavity of the connecting column two, and an incomplete gear rotatably connected to the outer side of the connecting shaft two.

[0008] Furthermore, a connecting column three is fixedly connected to the outer side of the cylinder, a fixing column four is fixedly connected to one end of the connecting column three, a rack is slidably connected to the inner cavity of the fixing column four, and the connecting column four is fixedly connected to the outer side of the upper end of the rack.

[0009] Furthermore, two sets of the four connecting columns are symmetrically arranged, and a measuring device is fixedly connected between the two sets of the four connecting columns symmetrically arranged.

[0010] Furthermore, a fixing column five is fixedly connected to the top of the connecting column three, a telescopic rod is slidably connected to the inner cavity of the fixing column five, a protective top plate is fixedly connected to the top of the telescopic rod, and the protective top plate is fixedly connected to the top of the measuring instrument.

[0011] Furthermore, a moving mechanism is fixedly connected to the top of the base plate. The moving mechanism includes a fixed column, which is fixedly connected to one side of the base plate. A motor is fixedly connected to the top of the fixed column.

[0012] Furthermore, a second fixing column is fixedly connected to the top of the base plate. Two sets of the second fixing columns are symmetrically arranged. A worm gear is rotatably connected between the two sets of the second fixing columns, and a moving shaft is fixedly connected between the two sets of the second fixing columns.

[0013] Furthermore, a moving column is slidably connected to the outer side of the moving shaft and the worm gear, a connecting shaft is rotatably connected to the inner cavity of the moving column, a worm wheel is rotatably connected to the outer side of the connecting shaft, and the worm wheel is rotatably connected to the motor through the moving shaft and the moving column.

[0014] This utility model has the following beneficial effects:

[0015] I. This utility model is equipped with a lifting mechanism. Fixed column three is slidably mounted on the upper side of the base plate. Its top end is fixed to the cylinder through connecting column one. The upper end of the cylinder is slidably connected to the telescopic column. The top end of the telescopic column is connected to connecting column two. The outer side of the connecting shaft two inside the connecting column two is rotatably connected to an incomplete gear. When the cylinder is inflated or deflated, it drives the telescopic column to rise and fall along the cylinder axis, driving connecting column two and the incomplete gear to move synchronously. At the same time, the incomplete gear meshes with the rack. The rack sliding inside the fixed column four drives the symmetrically arranged connecting column four and the measuring device to achieve vertical height adjustment. The lifting mechanism drives the measuring device to measure the water level at different heights to improve the accuracy of the measurement.

[0016] II. Based on the aforementioned beneficial effects, a moving mechanism is also provided. The motor is fixed to the top of the first fixed column on the base plate. After being powered on, it drives the worm gear on the outside of the first connecting shaft to rotate. The worm gear meshes with the worm, causing the worm to rotate between the two sets of second fixed columns. Since the moving column is simultaneously sleeved on the outside of the worm and the moving shaft, and the spiral teeth of the worm are threaded with the inner wall of the moving column, when the worm rotates, it pushes the moving column to slide horizontally along the moving shaft, thereby driving the lifting mechanism and the measuring instrument to move laterally, realizing the measurement of different horizontal points in the same water area. The worm gear transmission has a self-locking characteristic, which can ensure that the moving column is fixed in any position, improving the measurement stability. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a protective bracket for a portable water level measuring instrument, including a base plate 1. A lifting mechanism 3 is slidably arranged on the upper side of the base plate 1. The lifting mechanism 3 includes a fixed column 31, which is slidably arranged on the upper side of the bottom end. A connecting column 32 is fixedly connected to the top of the fixed column 31. A cylinder 33 is fixedly connected to the top of the connecting column 32. A telescopic column 34 is slidably connected to the upper end of the cylinder 33. A connecting column 35 is fixedly connected to the top of the telescopic column 34. A connecting shaft 36 is rotatably connected to the inner cavity of the connecting column 35. An incomplete gear 37 is rotatably connected to the outer side of the connecting shaft 36.

[0027] Specifically, cylinder 33 is a double-acting cylinder with a diameter of 32mm and a stroke of 1500mm. The cylinder body of cylinder 33 is fixed to the top of connecting column 1 32, and its internal piston is fixedly connected to telescopic column 34. By filling or deflating the cylinder 33, the piston is driven to move linearly along the axis of cylinder 33, thereby driving telescopic column 34 to rise and fall synchronously. The top of telescopic column 34 is fixedly connected to connecting column 2 35, thereby realizing the adjustment of the vertical height of connecting column 2 35 and measuring device 4 to adapt to the measurement needs of different water depths.

[0028] For example, the cylinder 33 drives the telescopic column 34 to rise and fall by inflating or deflating, which in turn drives the two symmetrically arranged incomplete gears 37 to deflect by the connecting column 35 and connecting shaft 36. Then, the meshing effect of the incomplete gears 37 and the rack 310 drives the measuring device 4 to rise and fall to adjust its position.

[0029] A connecting post 38 is fixedly connected to the outer side of cylinder 33. A fixing post 4 39 is fixedly connected to one end of connecting post 38. A rack 310 is slidably connected to the inner cavity of fixing post 4 39. A connecting post 4 311 is fixedly connected to the outer side of the upper end of rack 310.

[0030] For example, there are two symmetrically arranged racks 310, which mesh with two symmetrically arranged incomplete gears 37, and drive the measuring device 4 to rise and fall through the connecting column 311.

[0031] Two sets of connecting columns 4 311 are symmetrically arranged, and a measuring device 4 is fixedly connected between the two sets of symmetrically arranged connecting columns 4 311.

[0032] For example, the measuring device 4 is used to measure the water level. The measuring device 4 uses a radar antenna to emit microwave signals. After the signal is reflected by the water surface, the water level is calculated by the Doppler effect or the time difference method. Doppler effect: the water level is measured by the frequency change of the reflected signal; time difference method: the distance is calculated by the round-trip time of the signal. Features: non-contact, large measuring range (up to tens of meters), suitable for harsh environments such as rainstorms and icing, and high accuracy (error ≤ ±1cm).

[0033] The top of the connecting column 38 is fixedly connected to the fixing column 5 312, the inner cavity of the fixing column 5 312 is slidably connected to the telescopic rod 313, the top of the telescopic rod 313 is fixedly connected to the protective top plate 314, and the protective top plate 314 is fixedly connected to the top of the measuring instrument 4.

[0034] For example, when the device is impacted by an object falling from above, the protective top plate 314 can absorb the impact force to prevent damage to the display screen or sensors of the measuring device 4.

[0035] Working principle: Fixed column 31 is slidably set on the upper side of base plate 1. Its top end is fixed to cylinder 33 through connecting column 1 32. Telescopic column 34 is slidably connected to the upper end of cylinder 33. Connecting column 2 35 is connected to the top end of telescopic column 34. Incomplete gear 37 is rotatably connected to the outer side of connecting shaft 2 36 inside the cavity of connecting column 2 35. When cylinder 33 is inflated or deflated, it drives telescopic column 34 to rise and fall along the axis of cylinder 33, driving connecting column 2 35 and incomplete gear 37 to move synchronously. At the same time, incomplete gear 37 meshes with rack 310. The rack 310 sliding inside fixed column 4 39 drives the symmetrically arranged connecting column 4 311 and measuring device 4 to achieve vertical height adjustment.

[0036] In this step, the lifting mechanism 3 drives the measuring device 4 to measure the water level at different heights to improve the accuracy of the measurement.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes a moving mechanism 2.

[0038] A moving mechanism 2 is fixedly connected to the top of the base plate 1. The moving mechanism 2 includes a fixed column 21, which is fixedly connected to one side of the base plate 1. A motor 22 is fixedly connected to the top of the fixed column 21.

[0039] Specifically, the motor 22 is a DC geared motor 22 with a voltage of 24V, a torque of 1.5N·m, a speed of 100r / min, and a protection level of IP65. The motor 22 is fixed to the top of the fixing post 21 of the base plate 1. Its output shaft is rotatably connected to the worm gear 28 through the connecting shaft 27. When the motor 22 is powered on, it drives the worm gear 28 to rotate. The worm gear 28 meshes with the worm 24, driving the worm 24 to rotate between the fixing posts 23.

[0040] For example, the motor 22 is connected to the base plate 1 via a fixed post 21.

[0041] The top of the base plate 1 is fixedly connected to a second fixed column 23. Two sets of the second fixed columns 23 are symmetrically arranged. A worm gear 24 is rotatably connected between the two sets of the symmetrically arranged second fixed columns 23. A moving shaft 25 is fixedly connected between the two sets of the symmetrically arranged second fixed columns 23.

[0042] For example, the worm 24 is meshed with the worm wheel 28 and rotates under the drive of the worm wheel 28.

[0043] A movable column 26 is slidably connected to the outer side of the movable shaft 25 and the worm gear 24. A connecting shaft 27 is rotatably connected to the inner cavity of the movable column 26. A worm wheel 28 is rotatably connected to the outer side of the connecting shaft 27. The worm wheel 28 is rotatably connected to the motor 22 through the movable shaft 25 and the movable column 26.

[0044] For example, the worm gear 28 is electrically connected to the motor 22 via the connecting shaft 27. Driven by the motor 22, the worm gear 28 rotates and meshes with the worm 24. When the worm 24 rotates, it drives the moving column 26 on its outer side to move left and right along its outer side and the outer side of the moving shaft 25, thereby driving the lifting mechanism 3 and the measuring device 4 at the upper end to adjust their positions left and right.

[0045] Working principle: The motor 22 is fixed to the top of the fixed column 21 of the base plate 1. After being powered on, it drives the worm wheel 28 on the outside of the connecting shaft 27 to rotate. The worm wheel 28 meshes with the worm 24, causing the worm 24 to rotate between the two sets of fixed columns 23. Since the moving column 26 is sleeved on the outside of both the worm 24 and the moving shaft 25, and the helical teeth of the worm 24 are threaded with the inner wall of the moving column 26, when the worm 24 rotates, it pushes the moving column 26 to slide horizontally along the moving shaft 25, thereby driving the lifting mechanism 3 and the measuring device 4 to move laterally, so as to realize the measurement of different horizontal points in the same water area. The worm 24 and worm wheel 28 transmission has a self-locking characteristic, which can ensure that the moving column 26 is fixed in any position, improving the measurement stability.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
