Description

Technical Field

[0001] The utility model relates to the technical field of hydrological measurement, in particular to a hydrological rain gauge support component. Background Art

[0002] Hydrological rainfall measurement is the process of quantitatively observing and recording rainfall using specific techniques and equipment. Its basic principle is to utilize the physical effects of rainwater on measuring equipment (such as gravity, pressure, and displacement) to convert changes in rainfall into observable and recordable signals or data. The rain gauge method is one of the primary methods of hydrological rainfall measurement. It directly measures rainfall using a rain gauge (rain gauge).

[0003] Common rain gauges include tipping bucket rain gauges, weighing rain gauges, and ultrasonic rain gauges. Tipping bucket rain gauges record rainfall by the number of times the bucket flips; weighing rain gauges calculate rainfall by measuring the pressure or weight change of rainwater on the container; and ultrasonic rain gauges measure rainfall by using the propagation time of ultrasonic signals in the air.

[0004] Due to the special working environment, rain gauges are exposed to the outdoors for a long time, so they have certain requirements for support and protection related technologies. However, existing rain gauges cannot adapt to long-term use and measurement in areas where soil and water erosion is prone to occur. The gauges will be affected by soil and water erosion, causing them to deflect, and their support components cannot provide effective support, adjustment and protection in this case, which affects the accuracy of the measurement and also causes safety hazards to the equipment. Utility Model Content

[0005] In order to solve the problem in the prior art that a rain gauge is prone to deflection in a soil erosion area, which affects the measurement accuracy, the utility model provides a hydrological rain gauge support assembly.

[0006] The technical solution adopted in this utility model is:

[0007] A hydrological rain gauge support assembly comprises a measuring cylinder, the bottom of the measuring cylinder is connected to a support base, and a support adjustment assembly and a rotation support assembly are respectively connected between the support base and the measuring cylinder;

[0008] The support adjustment assembly is divided into at least two groups and is respectively arranged on the side of the measuring cylinder. The support adjustment assembly includes two support plates respectively connected to the side of the measuring cylinder and the surface of the support base. The two support plates are hinged to each other. An angle adjustment drive mechanism for adjusting the rotation of the measuring cylinder around the rotating support assembly is connected between the two support plates. The angle adjustment drive mechanism includes a drive cylinder, and both ends of the drive cylinder are respectively hinged to the outer surfaces of the two support plates.

[0009] Furthermore, the rotating support assembly includes a rotating platform, an articulated rotating seat is connected between the rotating platform and the support base, and an anti-dumping spring is also connected between the rotating platform and the support base.

[0010] Furthermore, the driving cylinder includes a piston rod and a cylinder barrel, one end of the piston rod is installed in the cylinder barrel, a first support hinge support is connected between the other end of the piston rod and the support plate, and a second support hinge support is connected between the bottom end of the cylinder barrel and the support plate.

[0011] Furthermore, a limiting block is provided on a side of the support plate close to the measuring cylinder, and a limiting groove cooperating with the limiting block is provided on the outer surface of the measuring cylinder.

[0012] Furthermore, a measuring opening is provided on the top surface of the measuring cylinder, and a filter is installed at a position in the measuring cylinder corresponding to the measuring opening.

[0013] Furthermore, a protective cover assembly is connected to the top of the measuring tube, and the protective cover assembly includes a water guide cover connected to the top surface of the measuring tube and a protective eaves connected to the bottom end of the water guide cover, and a reinforcing fixing ring is connected between the protective eaves and the water guide cover.

[0014] The beneficial effects of the utility model are:

[0015] The rain gauge support assembly of the present invention has two functions: support and protection and horizontal adjustment. The support base raises the entire support of the meter to prevent the meter from being eroded by the environment and rainwater for a long time. The support plate provides certain support and protection to the entire meter while adjusting the horizontal angle of the meter to place the meter at the best angle for collecting rainwater. Specifically, under the support of the support plate, the meter can adjust the horizontal plane angle based on the support of the rotating support assembly and driven by the angle adjustment drive mechanism, so that the rainwater collection opening above is not affected by the terrain and is in the best collection and measurement position, thereby improving the accuracy of the measurement; this structure can be used and measured for a long time in areas where soil and water are prone to loss, and will not be affected by soil and water loss and cause the meter to deflect. Its support assembly can provide effective support, adjustment and protection in this case, thereby ensuring the accuracy of the measurement and effectively avoiding safety hazards of the equipment.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] This utility model is a hydrological rain gauge support assembly, please refer to Figure 1 、 Figure 2 , including a measuring cylinder 1, the bottom of the measuring cylinder 1 is connected to a support base 2, and a support adjustment component 3 and a rotation support component 4 are respectively connected between the support base 2 and the measuring cylinder 1;

[0025] Specifically, the support adjustment assembly 3 is divided into at least two groups and is respectively arranged on the side of the measuring tube 1. There can be two or four groups of support adjustment assemblies 3. When four groups of support adjustment assemblies 3 are used, in order to meet the adjustment requirements in each direction, they can be set as components that can be adjusted in any direction, for example, using universal joints for connection and adjustment; the support adjustment assembly 3 includes two support plates 31 respectively connected to the side of the measuring tube 1 and the surface of the support base 2, the two support plates 31 are hinged to each other, and an angle adjustment drive mechanism 32 for adjusting the rotation of the measuring tube 1 around the rotating support assembly 4 is connected between the two support plates 31. The angle adjustment drive mechanism 32 includes a drive cylinder 321, and the two ends of the drive cylinder 321 are respectively hinged to the outer surfaces of the two support plates 31.

[0026] The support assembly is first securely mounted on the ground or at a designated location using the support base 2. As the core component of rainfall collection, the stability of the measuring tube 1 is crucial. The support adjustment assembly 3 allows the inclination angle of the measuring tube 1 to be adjusted as needed to accommodate varying terrain or measurement requirements. The rotating support assembly 4 allows the measuring tube 1 to rotate within a certain range, facilitating adjustments to measurement direction or maintenance.

[0027] The support adjustment assembly 3 connects the measuring cylinder 1 and the support base 2 via two hinged support plates 31, allowing relative movement between the support plates 31 to adjust the position of the measuring cylinder 1. The angle adjustment drive mechanism 32 (e.g., the drive cylinder 321) is hinged to the support plates 31 to precisely control the rotation angle of the measuring cylinder 1.

[0028] In this embodiment, the support base 2 ensures the stability of the overall structure. At the same time, under the joint action of the support adjustment component 3 and the rotation support component 4, the measuring tube 1 can flexibly adapt to various measurement environments, thereby improving the accuracy and convenience of measurement.

[0029] Example 2

[0030] This example is a further implementation plan based on Example 1. Please refer to Figure 1 、 Figure 3 The rotating support assembly 4 includes a rotating platform 41, an articulated rotating seat 42 is connected between the rotating platform 41 and the support base 2, and an anti-dumping spring 43 is also connected between the rotating platform 41 and the support base 2.

[0031] The rotating platform 41, directly supporting the measuring tube 1, is connected to the support base 2 via an articulated rotating base 42, allowing the measuring tube 1 to rotate freely within a certain range. The presence of an anti-tilt spring 43 enhances system stability, preventing the measuring tube 1 from accidentally tipping over due to factors such as wind in extreme weather conditions. The anti-tilt spring 43 also acts as a buffer and stabilizer against lateral forces acting on the measuring tube 1, reducing shaking and ensuring measurement accuracy.

[0032] The articulated swivel base 42 provides rotational freedom for the swivel platform 41 relative to the support base 2, while also ensuring structural strength and durability. This embodiment of the swivel support assembly 4 not only improves the flexibility of the measuring tube 1 but also enhances the wind resistance and stability of the entire support assembly, making it suitable for a variety of complex environments.

[0033] Example 3

[0034] This example is a further implementation plan based on Example 1. Please refer to Figure 2 The driving cylinder 321 includes a piston rod and a cylinder barrel. One end of the piston rod is installed in the cylinder barrel. A first support hinge support 322 is connected between the other end of the piston rod and the support plate 31. A second support hinge support 323 is connected between the bottom end of the cylinder barrel and the support plate 31.

[0035] When the angle of the measuring cylinder 1 needs to be adjusted, the piston rod of the driving cylinder 321 extends or retracts under the action of air pressure, pushing or pulling the support plate 31 through the first support hinge support 322 and the second support hinge support 323, thereby driving the measuring cylinder 1 to rotate around the rotating support assembly 4 to the desired angle. The relative movement between the piston rod and the cylinder is the basis for the operation of the driving cylinder 321, and the support hinge support ensures that the connection between the cylinder and the support plate 31 is both stable and flexible, and can transmit sufficient torque to achieve angle adjustment. As the core component of the angle adjustment drive mechanism 32, the driving cylinder 321 achieves fine-tuning of the rotation angle of the measuring cylinder 1 by precisely controlling the extension and contraction of the piston rod, thereby improving the measurement accuracy and operability.

[0036] Example 4

[0037] This example is a further implementation plan based on Example 1. Please refer to Figure 1 A limiting block 5 is provided on one side of the support plate 31 close to the measuring cylinder 1 , and a limiting groove 6 cooperating with the limiting block 5 is provided on the outer surface of the measuring cylinder 1 .

[0038] During adjustment of the measuring tube 1's angle, the stopper 5 slides along the stopper slot 6, guiding and limiting the measuring tube's range of movement. This prevents excessive rotation from causing the measuring tube 1 to fall out of the device, potentially damaging the structure or causing measurement errors. The coordination of the stopper 5 and the stopper slot 6 ensures the stability and safety of the measuring tube 1 during rotation. This embodiment effectively improves the reliability of the support assembly.

[0039] Example 5

[0040] This example is a further implementation plan based on Example 1. Please refer to Figure 4 A measuring opening is provided on the top surface of the measuring cylinder 1 , and a filter screen 11 is installed at a position corresponding to the measuring opening in the measuring cylinder 1 .

[0041] Rainwater enters measuring tube 1 through the measuring opening, and filter 11 effectively blocks impurities and large particles, ensuring the purity of the rainwater. Filter 11, acting as a pretreatment device, reduces measurement errors, extends the service life of measuring tube 1, and improves measurement accuracy. This embodiment improves measurement accuracy and enhances the durability and practicality of the measuring device, making it suitable for long-term monitoring in various adverse weather conditions.

[0042] Example 6

[0043] This example is a further implementation plan based on Example 1. Please refer to Figure 1 、 Figure 4The top of the measuring tube 1 is connected to a protective cover assembly 7, which includes a water guide cover 71 connected to the top surface of the measuring tube 1 and a protective eaves 72 connected to the bottom end of the water guide cover 71. A reinforcing fixing ring 73 is connected between the protective eaves 72 and the water guide cover 71.

[0044] The protective cover assembly 7 protects the measuring opening from external interference, such as fallen leaves, dust, etc. The water guide cover 71 guides rainwater to discharge out of the device, and the protective eaves 72 prevents rainwater from splashing in from the side or external debris from falling into the device. The reinforced fixing ring 73 ensures a firm connection between the water guide cover 71 and the protective eaves 72, thereby improving the structural strength of the entire protective cover assembly 7. The design of the water guide cover 71 and the protective eaves 72 is based on the principles of fluid dynamics, which optimizes the rainwater discharge path and reduces rainwater erosion and impurity mixing. The reinforced fixing ring 73 ensures the overall stability and durability of the protective cover assembly 7 by increasing the number and strength of the connection points. The protective cover assembly 7 of this embodiment not only improves the protection performance of the measuring instrument, but also ensures the accuracy and reliability of the measurement data.

[0045] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
