Technical Field
[0001] This utility model relates to the field of water level measuring instruments, and in particular to a portable water level measuring instrument for water conservancy projects. Background Technology
[0002] In the field of water conservancy engineering, portable water level gauges are portable devices used for the rapid and accurate measurement of water level depth. They can be widely applied in rivers, lakes, reservoirs, canals, and other scenarios. Utilizing technologies such as electrical measurement, acoustic waves, and pressure, they acquire water level data in real time, providing crucial foundational information for water resource management, water conservancy project construction, and hydrological monitoring, thus contributing to the convenience, efficiency, and accuracy of on-site water conservancy measurements.
[0003] In the existing technology, when using a water level measuring instrument for hydraulic engineering, the operator holds the measuring tape and gradually lowers the probe to the water surface. After water enters the sensing hole that the probe contacts, the device will emit a beep. However, during this process, the operator needs to hold the measuring tape for a long time to prevent the measuring instrument from falling into the water and causing inaccurate readings. Therefore, a portable water level measuring instrument for hydraulic engineering is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a portable water level measuring instrument for hydraulic engineering, which aims to improve the problem in the prior art that "the operator needs to pull out the flexible ruler for a long time to prevent the measuring instrument from falling into the water and causing inaccurate readings".
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a portable water level measuring instrument for hydraulic engineering, including a support frame, a convergence wheel rotatably connected to the right surface of the support frame, a flexible ruler provided on the inner wall of the convergence wheel, a locking component provided on the right surface of the convergence wheel, a probe fixedly connected to the end of the flexible ruler away from the convergence wheel, a sensing hole provided at the lower part of the probe, and a floating component provided on the outer wall of the probe; the floating component includes a rotating sleeve, the inner wall of the rotating sleeve being threadedly connected to the outer wall of the probe through a threaded groove, a fixed sleeve fixedly connected to the upper part of the outer wall of the rotating sleeve, a sliding sleeve slidably connected to the outer wall of the rotating sleeve, multiple sets of swing rods hinged to the outer wall of the fixed sleeve, a buoyancy ball fixedly connected to the lower end of the swing rod, multiple sets of support rods hinged to the outer wall of the sliding sleeve, the end of the support rod away from the sliding sleeve rotatably connected to the outer wall of the swing rod, a slot being opened on the outer wall of the rotating sleeve, and a plug being inserted into the inner wall of the slot.
[0006] As a further description of the above technical solution:
[0007] The outer wall of the sliding sleeve is fixedly connected to a protective box, and the outer walls of the inserts are slidably connected to the inner walls of the sliding sleeve and the protective box.
[0008] As a further description of the above technical solution:
[0009] A connecting rod is slidably connected to the inner wall of the protective box. The front surface of the connecting rod is fixedly connected to the rear surface of the insert block, and a pull plate is fixedly connected to the front surface of the connecting rod.
[0010] As a further description of the above technical solution:
[0011] The insert and the protective box are elastically connected by a support spring.
[0012] As a further description of the above technical solution:
[0013] The locking assembly includes a support shaft, the left surface of which is fixedly connected to the right surface of the retracting wheel, and a threaded rod is threadedly connected to the inner wall of the support shaft.
[0014] As a further description of the above technical solution:
[0015] A baffle is fixedly connected to the right surface of the threaded rod, and the baffle is U-shaped.
[0016] As a further description of the above technical solution:
[0017] The support shaft has grooves at both the top and bottom ends, and a slider is slidably connected to the inner wall of the groove. The slider is T-shaped and is adapted to the groove.
[0018] As a further description of the above technical solution:
[0019] Both sliders are fixedly connected to a sliding disk at the end away from the support shaft, and the left surface of the sliding disk is in contact with the gathering wheel.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the floating component allows the operator to insert the plug into different slots when measuring water level, causing the sliding sleeve to move and support the swing rod. Then, the probe is placed in the water, and the buoyancy ball will make the probe float upright on the water surface, eliminating the need for the operator to hold it for a long time. At the same time, when measuring some thinner pipes, the sliding sleeve can be adjusted so that the buoyancy ball can contact the inner wall of the pipe, which enhances the stability of the probe and does not affect the probe's detection range too much due to the buoyancy ball.
[0022] 2. In this utility model, the locking component allows the operator to rotate the baffle to swing it 90° when measuring the water surface, and then remove the sliding plate. At this time, the measuring tape can be pulled out more quickly, avoiding the need for the operator to continuously rotate the retracting wheel when using the device, thus improving the work efficiency during measurement.

[0030] 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.
[0031] Reference Figures 1-3This utility model provides an embodiment of a portable water level measuring instrument for hydraulic engineering, including a support frame 1 for supporting the overall device and facilitating lifting by the operator. A retracting wheel 2 for retracting a flexible measuring tape 3 is rotatably connected to the right surface of the support frame 1. The inner wall of the retracting wheel 2 is provided with a flexible measuring tape 3 for supporting a probe 4 and measuring the water surface position. A locking component 6 for fixing a sliding disc 66 is provided on the right surface of the retracting wheel 2. A probe 4 for detecting water level height and emitting a buzzer after water enters the sensing hole 7 is fixedly connected to the end of the flexible measuring tape 3 away from the retracting wheel 2. A sensing hole 7 for triggering a signal to the probe 4 after water enters is provided at the lower part of the probe 4. A floating component 5 for assisting the probe 4 to float on the water surface is provided on the outer wall of the probe 4. The floating component 5 includes a rotating sleeve 51 for supporting a fixed sleeve 52 and a sliding sleeve 53. The inner wall of the rotating sleeve 51 is threaded to the outer wall of the probe 4 through a threaded groove 57. The threaded groove 57 is used for threading... The rotating sleeve 51 is self-locking to restrict its movement while allowing it to move up and down. A fixed sleeve 52 is fixedly connected to the upper part of the outer wall of the rotating sleeve 51 to support the swing rod 54. A sliding sleeve 53 is slidably connected to the outer wall of the rotating sleeve 51 to slide on the surface of the rotating sleeve 51 and drive the support rod 56 to swing. The outer wall of the fixed sleeve 52 is hinged to multiple sets of swing rods 54 to support the buoyancy ball 55. The lower end of the swing rod 54 is fixedly connected to the buoyancy ball 55 to provide buoyancy for the probe 4. The outer wall of the sliding sleeve 53 is hinged to multiple sets of support rods 56 to lift the swing rod 54 by the movement of the sliding sleeve 53. The end of the outer wall of the support rod 56 away from the sliding sleeve 53 is rotatably connected to the outer wall of the swing rod 54. The outer wall of the rotating sleeve 51 has a slot 58 for accommodating the insert block 59. The inner wall of the slot 58 is inserted into the slot 58 to fix the sliding sleeve 53.
[0032] Reference Figures 2-5 The outer wall of the sliding sleeve 53 is fixedly connected to a protective box 510 for protecting the support spring 513. The outer wall of the insert 59 is slidably connected to the inner wall of the sliding sleeve 53 and the protective box 510. The inner wall of the protective box 510 is slidably connected to a connecting rod 512 for connecting the pull plate 511 and the insert 59 together. The front surface of the connecting rod 512 is fixedly connected to the rear surface of the insert 59. The front surface of the connecting rod 512 is fixedly connected to a pull plate 511 for facilitating the operator to pull the insert 59. The insert 59 and the protective box 510 are elastically connected by a support spring 513 for making the insert 59 continuously subjected to force and more tightly inserted into the slot 58. The locking assembly 6 includes a support shaft 61 for supporting other structures of the locking assembly 6. The left surface of the support shaft 61 is fixedly connected to the right surface of the retracting wheel 2. The inner wall of the support shaft 61 is threadedly connected to a threaded rod 62 for driving the baffle 63 to move when the baffle 63 rotates and using the threaded self-locking to fix the baffle 63.
[0033] Reference Figures 3-5 A baffle 63 is fixedly connected to the right surface of the threaded rod 62 to block the sliding disk 66 by its own rotation. The baffle 63 is U-shaped so that both ends of the baffle 63 can be tightly attached to the sliding disk 66. The upper and lower ends of the support shaft 61 are provided with grooves 64 to support the sliding of the slider 65. The inner wall of the groove 64 is slidably connected to a slider 65 for sliding in the groove 64 so that the sliding disk 66 follows the rotation of the gathering wheel 2. The slider 65 is T-shaped and fits the groove 64. The ends of the two sliders 65 away from the support shaft 61 are fixedly connected to the sliding disk 66 to block the soft ruler 3 and prevent the soft ruler 3 from falling off. The left surface of the sliding disk 66 is in contact with the gathering wheel 2.
[0034] Working principle: First, hold the water level measuring instrument to the expected position, and then rotate the baffle 63 to the 90° position. The rotation of the baffle 63 drives the threaded rod 62 to move outward and rotate, so that the restriction of the sliding plate 66 is released. Then, the sliding plate 66 is removed along the slide groove 64. At this time, a relatively fast line laying operation can be achieved.
[0035] Then, pull plate 511 is pulled, and the movement of pull plate 511 drives the movement of connecting rod 512, which in turn drives the insert block 59 to disengage from the inner wall of slot 58. At this time, support spring 513 is compressed. When testing a wider water surface, rotating sleeve 51 can be pulled down. The downward movement of rotating sleeve 51 causes support rod 56 to deflect, which in turn causes support rod 56 to drive swing rod 54 to deflect to a 45° position, so that the device has good stability. Then, rotating sleeve 51 is rotated, causing rotating sleeve 51 to move downward along threaded groove 57, so that after swing rod 54 drives buoyancy ball 55 to deflect, only the sensing hole 7 part of the device can still be submerged underwater.
[0036] 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.
