Description

Technical Field

[0001] This utility model relates to the field of water level gauge technology, specifically a water level gauge for water conservancy information measurement. Background Technology

[0002] A water level gauge, also called a liquid level gauge, is used to measure and record the water level of water bodies such as rivers and lakes. Water level gauges can be divided into various types according to their measurement principles. Among them, the radar water level gauge is a non-contact measuring device. Its working principle is as follows: the sensor controls the antenna to emit radar pulses towards the water surface, and the antenna receives the pulses reflected back from the water surface and records the time from the emission of the radar pulse to the reception of the radar pulse. Since the propagation speed of electromagnetic waves is constant, the distance from the radar water level gauge to the water surface can be calculated.

[0003] A search revealed that patent authorization announcement number CN219694289U discloses a water level gauge for water conservancy information measurement, "including a column, a support rod installed on the upper outer wall of the column, a protective shell at the front end of the support rod, and a loading and unloading assembly installed on the inner side wall of the protective shell. The loading and unloading assembly includes a first fixing plate, a sliding rod fixedly connected to the rear side of the first fixing plate through a connecting hole, a second fixing plate at the other end of the sliding rod, a bidirectional screw rotatably connected to the rear side of the first fixing plate through a through hole, and a first clamping block and a second clamping block connected to the left and right sides of the bidirectional screw through threads. By setting up a protective shell and a loading and unloading assembly, the problem of water level gauges being easily damaged due to the lack of protective components, and the cumbersome installation and disassembly of water level gauges, is solved, making the water level gauge more effective." However, the support rod of the aforementioned existing water level gauge for water conservancy information measurement cannot be adjusted in length, that is, the distance between the water level gauge and the column cannot be adjusted. When the column is installed far from the water surface, the water level gauge may fail to detect the water surface. Utility Model Content

[0012] 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.

[0013] Example: Figure 1-4As shown, this utility model provides a water level gauge for water conservancy information measurement, including a column 1, a sliding column 2 slidably mounted on the column 1, a lifting assembly 10 installed inside the column 1, a sleeve 8 rotatably sleeved on the sliding column 2, a rotating assembly 11 installed inside the sliding column 2, a support rod 3 fixedly mounted on one side of the sleeve 8, a sliding rod 4 slidably mounted inside the support rod 3, an mounting plate 5 fixedly mounted on one end of the sliding rod 4, a water level gauge body 6 fixedly mounted on the mounting plate 5, and a threaded rod 12 rotatably mounted inside the support rod 3. The threaded rod 12 is threaded into the sliding rod 4. A first bevel gear 13 is fixedly installed at one end of the threaded rod 12. A third motor 15 is fixedly installed at the bottom end of the support rod 3. A second bevel gear 14 is fixedly installed at the output end of the third motor 15, and the second bevel gear 14 meshes with the first bevel gear 13. The column 1 can be installed at a designated location on the riverbank using anchor bolts. If the installation location of the column 1 is far from the water surface, i.e., the water level gauge body 6 is not above the water surface, a third motor 15 can be used as needed. Motor 15 drives the second bevel gear 14 to rotate, the second bevel gear 14 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the sliding rod 4 to slide out from the support rod 3 until the water level gauge body 6 installed at the end of the sliding rod 4 is above the water surface. The water level gauge body 6 is existing technology and is a radar water level gauge commonly used in water level measurement. It calculates the water level by emitting microwave (radar wave) pulses to the water surface and receiving the echoes based on the electromagnetic wave propagation time. When it is necessary to repair or replace the water level gauge body 6, it is dangerous for maintenance personnel to climb up and down because the column 1 is high. The rotating component 11 can be used to drive the sleeve 8, support rod 3, water level gauge body 6, etc. to rotate, so that the water level gauge body 6 rotates from above the water surface to above the ground. Then, the lifting component 10 is used to drive the sliding column 2 to slide down along the column 1. The sliding column 2 drives the sleeve 8, support rod 3, water level gauge body 6, etc. to descend to a suitable height, thereby achieving the purpose of facilitating the repair and replacement of the water level gauge body 6.

[0014] The lifting assembly 10 includes a lead screw 102, which is rotatably installed inside the column 1 and threaded into the sliding column 2. A first motor 101 is fixedly installed at the top of the column 1, and the output end of the first motor 101 is fixedly connected to the top of the lead screw 102. Bellows covers 9 are fixedly installed on both sides of the opening slot on the column 1. The first motor 101 drives the lead screw 102 to rotate, and the lead screw 102 drives the sliding column 2 to slide and rise along the column 1. The bellows covers 9 can protect the lead screw 102 and prevent foreign objects from affecting the transmission of the lead screw 102.

[0015] The rotating assembly 11 includes a drive shaft 1101, which is rotatably mounted inside the sliding column 2. A drive gear 1102 is fixedly mounted on the drive shaft 1101. A second motor 1103 is fixedly mounted on the top end of the sliding column 2, and the output end of the second motor 1103 is fixedly connected to the top end of the drive shaft 1101. The inner wall of the sleeve 8 is provided with annularly distributed toothed grooves 801, and the drive gear 1102 meshes with the toothed grooves 801 on the inner wall of the sleeve 8. The second motor 1103 can drive the drive shaft 1101 to rotate, and the drive shaft 1101 drives the drive gear 1102 to rotate. The drive gear 1102, by meshing with the toothed grooves 801 on the inner wall of the sleeve 8, drives the sleeve 8 to rotate on the sliding column 2.

[0016] A distribution box 7 is fixedly installed on one side of the support rod 3. The distribution box 7 contains the necessary electronic components and batteries for the device, which can supply power to the electrical components used in this device, or can be connected to an external power source.

[0017] Working principle: When using this utility model, the column 1 can be installed on the riverbank at a designated position using anchor bolts. If the installation position of the column 1 is far from the water surface, that is, the water level gauge body 6 is not above the water surface, the third motor 15 can be used to drive the second bevel gear 14 to rotate, the second bevel gear 14 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the sliding rod 4 to slide out from the support rod 3 until the water level gauge body 6 installed at the end of the sliding rod 4 is above the water surface. The water level gauge body 6 then emits microwave (radar wave) pulses to the water surface and receives the echoes to calculate the water level based on the electromagnetic wave propagation time. When the water level gauge body 6 needs to be repaired or replaced, the second motor 1103 is used to drive the drive shaft 1101 to rotate. The drive shaft 1101 drives the drive gear 1102 to rotate. The drive gear 1102 meshes with the tooth groove 801 on the inner wall of the sleeve 8, causing the sleeve 8 to rotate on the sliding column 2. The sleeve 8 drives the support rod 3, the water level gauge body 6, etc. to rotate, so that the water level gauge body 6 rotates from above the water surface to above the ground. Then, the first motor 101 drives the lead screw 102 to rotate. The lead screw 102 drives the sliding column 2 to slide down along the column 1. The sliding column 2 drives the sleeve 8, the support rod 3, the water level gauge body 6, etc. to descend to a suitable height, thereby achieving the purpose of facilitating the repair and replacement of the water level gauge body 6.
