Description

Technical Field

[0001] This utility model belongs to the technical field of water level measurement devices, specifically relating to a water level measurement device for water conservancy informatization. Background Technology

[0002] Water conservancy informatization refers to the process of fully utilizing modern information technology, deeply developing and utilizing water conservancy information resources, and modernizing the collection, transmission, storage, processing, and service of water conservancy information to comprehensively improve the efficiency and effectiveness of water conservancy activities. Water conservancy informatization can improve the timeliness and automation level of information collection and transmission, and is the foundation and important indicator of water conservancy modernization. Current water conservancy informatization measurements often use water level gauges, which are used to measure and record the water levels of rivers, lakes, and other water bodies.

[0003] Water level gauges can be classified into various types according to their measurement principles. Among them, radar water level gauges are non-contact measuring devices. Their working principle is as follows: the sensor controls the antenna to transmit radar pulses to the water surface, and the antenna receives the pulses reflected back from the water surface and records the time from transmitting the radar pulse to receiving 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.

[0004] Patent CN222503320U discloses a water level gauge for water conservancy information measurement, including a column, a base, a ladder rod, and a pipe clamp. The bottom of the column is mounted on the base, and the pipe clamp is installed on the column. A rod cylinder is welded to one side of the pipe clamp, and a rod body is movably inserted into the rod cylinder. An electric telescopic rod is installed at the bottom of the rod cylinder, and the cylinder of the electric telescopic rod is fixedly connected to the rod cylinder. The piston rod of the electric telescopic rod is fixedly connected to the rod body. A cover is installed at the free end of the rod body, and a snap-fit ​​structure is provided at the bottom of the cover. A snap-fit ​​opening is provided at the bottom of the snap-fit ​​structure, and an installation plate is installed inside the snap-fit ​​structure. A locking plate is installed on the side of the installation plate, and the locking plate is adapted to the snap-fit ​​opening. One of the locking plates has a threaded hole, and a limit hole is provided on the snap-fit ​​structure. A threaded locking handle is installed in the threaded hole, and the threaded locking handle is inserted and engaged with the limit hole. The water level gauge body is installed on the installation plate.

[0005] Existing water level gauges come in various sizes. For example, the RW-10 radar water level gauge measures 120*80*60mm, while the RW-20 radar water level gauge measures 150x100x80mm. However, the aforementioned technical solution uses a mounting plate to fix the water level gauge body. This mounting plate can only be used to install and fix a specific model of water level gauge. If it is necessary to replace the water level gauge with another model, the mounting plate cannot be matched with the other model, thus failing to guarantee normal water level measurement. Furthermore, the water level gauge in the aforementioned technical solution is located above the water surface, making it inconvenient to maintain the water level gauge. Summary of the Invention

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

[0026] The inventors discovered that current water level measuring devices can only be installed and fixed on a specific model of water level gauge. If it is necessary to replace it with a different model of water level gauge, the mounting plate cannot be matched with the other models of water level gauge, thus failing to ensure that the water level measurement can be carried out normally. 2. When maintaining the water level gauge, the gauge is always above the water surface, making maintenance inconvenient.

[0027] Based on the above findings, this application proposes a water level measurement device for water conservancy informatization. This device includes a rotating block 1, a telescopic rod 2, a driver 3, a water level gauge installer 4, a water level gauge 5, a base 6, and a column 7. This application utilizes the following design to enable the overall device to fix and install a water level gauge 5 of any size and specification, and to rotate the water level gauge to the bank for easy maintenance. Specifically: 1. The driver 2 can drive the water level measuring instrument installer 4 and the water level measuring instrument 5 located inside the water level measuring instrument installer 4 to rotate synchronously to the shore via the telescopic rod 2, so that personnel can install and maintain the water level measuring instrument. 2. The water level measuring instrument installer 4 can not only protect the water level measuring instrument 5 from rain, but also quickly install and fix water level measuring instruments 5 of different sizes, shortening the time for personnel to work at height and improving the daily maintenance efficiency of the water level measuring instrument.

[0028] The device provided in this embodiment is applicable to water conservancy information measurement in places such as rivers and lakes, and is also applicable to the installation of radar level gauges.

The rotating block 1 is a square block structure, and a through hole is provided on the rotating block 1 to connect the upper and lower parts. In this way, the rotating block 1 is rotatably connected to the column 7 through the through hole. The rotating block 1 is made of hard material, for example, the material of the rotating block 1 is an alloy.

[0031] The rotational connection between the rotating block 1 and the column 7 is a prior art technique. For example, the inner wall of the through hole of the rotating block 1 is provided with an annular groove, and the side of the corresponding column 7 is provided with an annular protrusion that is rotatably connected to the annular groove of the rotating block 1. The rotational connection between the rotating block 1 and the column 7 is achieved by matching the annular groove and the annular protrusion. The telescopic rod 2 is fixedly installed on the side of the rotating block 1, and the movable end of the telescopic rod 2 is fixedly connected to the water level measuring instrument installer 4; In this embodiment, the telescopic rod 2, driver 3, water level gauge 5, base 6, and column 7 are all existing technologies, and this embodiment does not improve upon them. For example, the telescopic rod 2 is an existing DTX type electric push rod; the driver 3 is an existing HG-SR1024K rotary motor; and the water level gauge 5 is either HXCAR820 or YWDZ-2000A-902.

[0032] The reinforcing rod 9, the telescopic rod 2, and the column 7 form a triangular structure, which improves the stability of the telescopic rod 2. Specifically, one end of the reinforcing rod 9 is fixedly connected to the side of the fixed end of the telescopic rod 2, and the other end is fixedly provided with a cylindrical rotating cylinder 91, which is rotatably connected to the column 7. The fixed connection method between the reinforcing rod 9 and the rotating cylinder 91, and the rotatable connection between the rotating cylinder 91 and the column 7 are existing technologies, and this utility model embodiment does not improve upon them. For example, the fixed connection method is welding. The inner wall of the rotating cylinder 91 is provided with an annular groove, and the corresponding side of the column 7 is provided with an annular protrusion that is rotatably connected to the annular groove of the rotating cylinder 91. The rotatable connection between the rotating cylinder 91 and the column 7 is achieved by matching the annular groove and the annular protrusion.

[0034] Specifically, the outer shell 41 is a cylindrical structure with the opening facing downwards; The second connecting rod 42 has an L-shaped rod structure. One end of the second connecting rod 42 is fixedly connected to the output end of the telescopic rod 2, and the other end passes through the outer shell 41 and is located at the upper end of the outer shell 41. The second connecting rod 42 is fixedly connected to the outer shell 41 by a nut. The fixing cylinder 43 is located at the end of the second connecting rod 42 away from the telescopic rod 2, and the fixing cylinder 43 is fixedly connected to the corner of the second connecting rod 42; Specifically, the fixed cylinder 43 includes an upper cylinder 43a, a lower cylinder 43b, a connecting ring 43c, and two limiting blocks 43d; The connecting ring 43c is located between the upper cylinder 43a and the lower cylinder 43b, and is fixedly connected to the upper cylinder 43a and the lower cylinder 43b respectively. Specifically, two guide plates are symmetrically provided on the side of the connecting ring 43c. Correspondingly, a guide groove is provided on the inner wall of the outer shell 41. In this way, through the cooperation of the guide plates and the guide groove, the groove on the side wall of the outer shell 1 can be quickly engaged with the second connecting rod 42, and the fixed cylinder 43 can be prevented from rotating inside the outer shell 41. Two limiting blocks 43d are symmetrically arranged at both ends of the upper cylinder 43a; specifically, each limiting block 43d has an arc-shaped block structure with a through hole connecting the upper and lower parts at its center, and each limiting block 43d is fixedly connected to the outer surface of the upper cylinder 43a. The two limiting blocks 43d are used to be fixedly connected to the water level measuring instrument clamping assembly 44.

[0035] In actual use, the water level gauge 5 is placed inside the upper cylinder 43a, and then the water level gauge 5 is clamped and fixed by the water level gauge clamping assembly 44.

[0036] The water level gauge clamping assembly 44 includes multiple limiting units 44a and an adjusting ring 44b; Among them, the multiple limiting units 44a are located inside the upper cylinder 43a and are arranged in a circle around the water level gauge 5, and each limiting unit 44a is in contact with the adjusting ring 44b. Specifically, such as Figure 7 and Figure 8 As shown, each limiting unit 44a includes an elastic sheet 44a-1, a connecting sheet 44a-2, a sliding rod 44a-3, and a guide block 44a-4; The elastic sheet 44a-1 has an arc-shaped sheet structure so as to fit against the side of the water level gauge 5; wherein, the elastic sheet 44a-1 is made of elastic material, for example, silicone or rubber; The connecting piece 44a-2 is similar to the elastic piece 44a-1, and has an arc-shaped sheet structure. The connecting piece 44a-2 is fixedly connected to the side of the elastic piece 44a-1 away from the water level gauge 5. Each guide block 44a-4 is set on the corresponding connecting piece 44a-2, and each guide block 44a-4 is a square block structure with a triangular groove on the side. The triangular groove is used to contact and connect with the adjusting ring 44b so as to adjust the position of each elastic piece 44a-1 according to the size of the water level gauge 5 so as to clamp and fix the water level gauge 5. The sliding rod 44a-3 is a straight rod. One end of the sliding rod 44a-3 is fixedly connected to the side of the guide block 44a-4, and the other end is slidably connected to the through hole opened on the inner wall of the upper cylinder 43a. In this embodiment of the invention, the connecting piece 44a-2, the sliding rod 44a-3, and the guide block 44a-4 are all made of hard materials. For example, the hard material is an alloy. The fixed connection method between the connecting piece 44a-2, the sliding rod 44a-3, and the guide block 44a-4 is the prior art. For example, the fixed connection method is welding.

[0037] The adjusting ring 44b includes an inner ring 44b-1, an outer ring 44b-2, two connecting rods 44b-3, multiple pressing rods 44b-4, and two screws 44b-5; wherein, the adjusting ring 44b is made of a hard material, for example, an alloy.

[0038] Specifically, the inner ring 44b-1 is located inside the upper cylinder 43a and between the limiting unit 44a and the inner wall of the upper cylinder 43a; The outer ring 44b-2 is located outside the upper cylinder 43a and is on the same horizontal plane as the inner ring 44b-1; Two connecting rods 44b-3 are symmetrically arranged between the inner ring 44b-1 and the outer ring 44b-2, and one end of each connecting rod 44b-3 is fixedly connected to the inner ring 44b-1, and the other end passes through the side wall of the upper cylinder 43a and is fixedly connected to the outer ring 44b-2. Multiple extrusion rods 44b-4 are vertically arranged on the inner ring 44b-1, and the upper end of each extrusion rod 44b-4 is located in the triangular groove of the corresponding guide block 44a-4. The upper end of each extrusion rod 44b-4 is fixedly provided with a triangular extrusion block 44b-6 that is in contact with the inclined surface of the triangular groove of the guide block 44a-4. Two screws 44b-5 are symmetrically arranged on the outer ring 44b-2, and each screw 44b-5 is fixedly connected to the outer ring 44b-2. In actual use, the upper end of each screw 44b-5 passes through the corresponding limiting block 43d on the side of the upper cylinder 43a, and then the screw 44b-5 is fixed in the central through hole of the limiting block 43d by the nut.

[0039] It should be noted that the fixed connection method between the inner ring 44b-1, outer ring 44b-2, connecting rod 44b-3, extrusion rod 44b-4 and screw 44b-5 in this embodiment of the present invention is all prior art, and this embodiment of the present invention does not improve upon it. For example, the fixed connection method is welding.

[0040] Example 2 Based on Example 1, the difference from Example 1 is as follows: Figure 4 and Figure 6 As shown, the water level measuring instrument clamping assembly 44 provided in this embodiment of the present invention also includes a flange fixing plate 44c and a rotating handle 44d.

[0041] Specifically, the flange fixing plate 44c is an annular plate structure, and the side of the flange fixing plate 44c is provided with threads; in practical applications, the flange fixing plate 44c is set inside the lower cylinder 43b, and correspondingly, the inner wall of the lower cylinder 43b is provided with threads for connecting with the side threads of the flange fixing plate 44c.

The arc-shaped rod is located between the two L-shaped connecting rods, and the two ends of the arc-shaped rod are fixedly connected to the lower ends of the L-shaped connecting rods on the same side.

[0042] The L-shaped connecting rod, the arc-shaped rod, and the connection relationship between the L-shaped connecting rod, the arc-shaped rod and the lower cylinder 43b are existing technologies, and this utility model embodiment does not improve upon them.

[0043] The usage process of the water level measuring instrument clamping assembly 44 provided in this embodiment of the utility model is as follows: First, place the water level gauge 5 inside the receiving cavity formed by the circumferential arrangement of each limiting unit 44a; Then, the maintenance personnel hold the outer ring 44b-2 with both hands and pull it upward. During this process, the outer ring 44b-2 drives each triangular extrusion block 44b-6 to move upward through the inner ring 44b-1. Under the cooperation of the triangular groove slope of each triangular extrusion block 44b-6 and the corresponding guide block 44a-4, each triangular extrusion block 44b-6 pushes the corresponding guide block 44a-4 to move closer to the water level gauge 5 until the elastic sheet 44a-1 is tightly attached to the side of the water level gauge 5. Then, the nut is rotated and tightened until it is in close contact with the upper surface of the limiting block 43d, thereby fixing the screw 44b-5. The screw 44b-5 is then used to fix the positions of the various triangular extrusion blocks 44b-6, so that the elastic sheet 44a-1 is always in close contact with the side of the water level gauge 5, thus completing the installation and fixing of the water level gauge 5.

[0044] After installing the water level gauge 5, the maintenance personnel hold the arc-shaped rod of the rotating handle 44d and rotate it to remove the flange fixing plate 44c, and then fix the flange 51 on the water level gauge 5. Then, the flange fixing plate 44c is installed and tightened so that the flange 51 of the water level gauge 5 is clamped and fixed between the connecting ring 43c and the flange fixing plate 44c, further improving the stability of the installation of the water level gauge 5. Finally, the cone 52 of the radar level gauge is fixedly connected to the flange 51.

[0045] It should be noted that the flange 51, the cone 52 of the radar level gauge, the fixed connection method between the flange 51 and the water level measuring instrument 5, and the fixed connection method between the flange 51 and the cone 52 provided in this utility model embodiment are all prior art, and this utility model embodiment does not improve them.

[0046] Implementation Cases Taking the replacement of water level measuring instrument 5 as an example, the use of the water level measuring device for water conservancy informatization provided in this embodiment of the utility model includes the following steps: S1: Start the driver 3. The driver 3 drives the telescopic rod 2 to rotate until the water level gauge installer is located on the shore, so that maintenance personnel can work at height. S2: Remove the nut on the bottom of the outer casing 41, and then remove the outer casing 41; S3: The maintenance personnel removed the two nuts on the limit block 43d and moved the outer ring 44b-2; S4: After the maintenance personnel grasp the rotating handle 44d, they remove the flange fixing plate 44c; S5: The maintenance personnel hold the water level gauge 5 with one hand and the flange 51 of the water level gauge 5 with the other hand in order to separate the water level gauge 5 and the flange 51. S6: After removing the old water level gauge 5, place the new water level gauge 5 into the receiving cavity formed by the limiting unit 44a; S7: The maintenance personnel hold the outer ring 44b-2 with both hands and pull the outer ring 44b-2 upward. During this process, the outer ring 44b-2 drives the triangular extrusion blocks 44b-6 to move upward through the inner ring 44b-1. Under the cooperation of the triangular groove slope of the triangular extrusion blocks 44b-6 and the corresponding guide blocks 44a-4, the triangular extrusion blocks 44b-6 push the corresponding guide blocks 44a-4 to move closer to the water level gauge 5 until the elastic sheet 44a-1 is tightly attached to the side of the water level gauge 5. S8: Tighten the nut on the screw 44b-5 until the nut is in close contact with the upper surface of the limit block 43d, thereby fixing the screw 44b-5. Then, the screw 44b-5 fixes the position of each triangular extrusion block 44b-6 so that the elastic sheet 44a-1 is always in close contact with the side of the water level gauge 5, thus completing the installation and fixing of the water level gauge 5. S9: Securely connect flange 51 to water level gauge 5; S10: Install and tighten the flange fixing plate 44c so that the flange 51 is clamped between the connecting ring 43c and the flange fixing plate 44c, further improving the stability of the water level gauge 5 installation; S11: Fix the cone 52 of the radar level gauge to the flange 51.
