Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hydrological monitoring auxiliary equipment, and specifically relates to a kind of hydrological monitoring instrument rapid calibration auxiliary instrument. BACKGROUND

[0002] Hydrological monitoring plays a crucial role in water resources management, flood control and drought resistance, water conservancy construction and operation and many other fields. Accurate and reliable hydrological data is the basis for ensuring the scientific development of these work, and the measurement accuracy of hydrological monitoring instruments directly determines the quality of hydrological data. To ensure the accuracy and reliability of the measurement results of hydrological monitoring instruments, regular calibration is an essential link.

[0003] However, the existing calibration of hydrological monitoring instruments faces many problems, and the current calibration means and equipment have obvious shortcomings, which cannot meet the needs of efficient and accurate calibration.

[0004] Firstly, the existing calibration method generally lacks precise docking positioning mechanism. When calibrating hydrological monitoring instruments, the relative position between the instrument and the calibration auxiliary equipment is difficult to determine accurately. Due to the lack of a precise docking positioning structure such as ten calibration holes arranged in a ring array on the outside of the calibration disc, the operator often has to rely on experience to roughly position, which is prone to inaccurate positioning. Once the relative position of the instrument and the auxiliary equipment deviates, errors will inevitably occur during calibration, which will affect the accuracy of the calibration results and make the hydrological monitoring instrument unable to achieve the desired measurement accuracy.

[0005] Secondly, the existing calibration auxiliary equipment has defects in installation stability. The lack of structures such as prismatic base fixing blocks fixed in a ring array on the corner surface of the calibration prismatic base of the auxiliary instrument makes it difficult to effectively engage with external fixing structures. This makes the calibration auxiliary equipment prone to shaking or shifting during placement and use, not only affecting the normal progress of calibration work, but also possibly damaging the instrument. At the same time, the existing equipment also lacks fourteen prismatic base fixing pads of silica gel material arranged in a ring array on the bottom corner surface, which cannot buffer the impact force during placement and cannot prevent the equipment from sliding or shifting through friction, resulting in a lack of stability in the calibration process and further reducing the accuracy and reliability of calibration.

[0006] Moreover, the existing calibration device has poor flexibility and cannot adapt to various complex calibration scenes. Most of the existing calibration devices have fixed structures, and it is difficult for the operator to flexibly adjust the position of the calibration component according to the actual calibration requirement. Without the combined design of the calibration rotating bearing, the calibration rotating shaft and the calibration rotating disc, the calibration rotating disc cannot rotate freely around the calibration rotating bearing, and the calibration standard rod and the calibration fine adjustment rod cannot correspond to different calibration positions of the hydrological monitoring instrument, so it is difficult to meet diversified calibration requirements.

[0007] In addition, the existing calibration method has deficiencies in precision fine adjustment. Since there is no calibration fine adjustment hole on the top plate of the calibration rotating disc, the operator cannot use a special fine adjustment tool to accurately fine adjust the position of the calibration rotating disc, and it is also difficult to further optimize the calibration precision after preliminary calibration by embedding the calibration fine adjustment rod on the other side of the calibration standard rod. This makes it difficult to achieve higher precision requirements in the calibration process, and limits the improvement of the measurement precision of the hydrological monitoring instrument.

[0008] Since the existing calibration method lacks a complete and efficient calibration process, the various links from positioning to adjustment and calibration lack coordination, resulting in long calibration time and low work efficiency. This not only increases the cost of calibration work, but also affects the normal use of the hydrological monitoring instrument, and cannot provide accurate and reliable hydrological data in time for related work.

[0009] In summary, the existing calibration of the hydrological monitoring instrument has problems such as inaccurate positioning, poor stability, insufficient flexibility, difficult precision fine adjustment and low calibration efficiency. Therefore, we improve it and propose a kind of hydrological monitoring instrument rapid calibration auxiliary instrument. Content of the utility model

The operator can flexibly adjust the orientation of the calibration standard rod and the calibration fine adjustment rod according to the actual calibration requirements, so that they correspond to different calibration parts of the hydrological monitoring instrument, adapting to various complex calibration scenes.

DETAILED DESCRIPTION

[0030] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0031] Therefore, the following detailed description of the embodiments of the utility model is not intended to limit the scope of the claimed utility model, but only represents some embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. It should be noted that the embodiments in the utility model and the features and technical schemes in the embodiments can be combined with each other without conflict. Similar signs and letters represent similar items in the following drawings, so further definition and explanation are not needed for them in subsequent drawings.

[0032] Embodiment 1: a hydrological monitoring instrument rapid calibration auxiliary instrument, comprising a calibration auxiliary instrument base center rod 1, and an auxiliary instrument calibration prism base 2 arranged above the calibration auxiliary instrument base center rod 1, a base positioning pin ring 3 is installed at the connection between the calibration auxiliary instrument base center rod 1 and the auxiliary instrument calibration prism base 2, wherein a prism base fixed block 4 is fixed on the corner surface of the auxiliary instrument calibration prism base 2, and a prism base fixed pad 5 is arranged on the bottom corner surface, and the prism base fixed pad 5 is made of rubber material.

[0033] The prism base fixed block 4 and the prism base fixed pad 5 are both provided with fourteen, and are arranged in a ring shape array on the outer surface of the auxiliary instrument calibration prism base 2.

[0034] The auxiliary instrument calibration prism base 2 is provided with a disc support cylinder 6 above the center. The disc support cylinder 6 is embedded with a circular cylinder hole 7 outside, and the auxiliary instrument calibration disc 8 is installed at the top end of the disc support cylinder 6, and the auxiliary instrument calibration disc 8 is provided with a calibration hole 9 outside. The auxiliary instrument calibration disc 8 is embedded with a calibration rotating bearing 10 at the center end, and the calibration hole 9 is provided with ten, which are arranged in a ring array on the outer surface of the calibration rotating bearing 10.

[0035] The calibration rotating bearing 10 is provided with a calibration rotating disc 11. The calibration rotating bearing 10 and the calibration rotating disc 11 are connected with a calibration rotating shaft 12, and the top plate of the calibration rotating disc 11 is respectively provided with a calibration fine adjustment hole 13 and a positioning block 14. The center of the calibration rotating disc 11 is penetrated by a calibration standard rod 15, and the other side of the calibration standard rod 15 is embedded with a calibration fine adjustment rod 16.

[0036] The cooperation between the base center rod and the prismatic base: the calibration auxiliary instrument base center rod 1 is the root of the entire instrument, providing vertical support for the upper structure. The calibration auxiliary instrument prismatic base 2 is located above it, and the two are connected through the base positioning pin ring 3. The base positioning pin ring 3 not only ensures the stability of the connection between the two, but also accurately determines the installation position of the calibration auxiliary instrument prismatic base 2, so that the upper structure of the entire auxiliary instrument is in the correct spatial position, laying the foundation for subsequent calibration work.

[0037] The function of the fixed clamping block and the fixed pad: on the corner surface of the calibration auxiliary instrument prismatic base 2, fourteen prismatic base fixed clamping blocks 4 are arranged in a ring array. These fixed clamping blocks can be clamped with external fixed structures, preliminarily fixing the auxiliary instrument at a specific position. The fourteen prismatic base fixed pads 5 on the bottom corner surface are also arranged in a ring array, made of rubber material. Silicone has good elasticity and friction, and the fixed pad can not only buffer the impact force generated when the auxiliary instrument is placed, protecting the instrument and the placement surface, but also increase the friction between the auxiliary instrument and the placement surface, preventing it from sliding or moving during use, ensuring the stability of the calibration process.

[0038] Disc support and connection: the disc support cylinder 6 installed above the center of the calibration auxiliary instrument prismatic base 2 provides stable support for the calibration disc 8 of the auxiliary instrument. The circular cylinder hole 7 embedded on the outside of the disc support cylinder 6 can be used to connect external power supply, data line or other auxiliary equipment, realizing data transmission or power supply function to meet various needs in the calibration process.

[0039] Positioning function of calibration holes: the calibration disc 8 of the auxiliary instrument is installed at the top of the disc support cylinder 6, and the ten calibration holes 9 arranged in a ring array on the outside of the calibration disc 8 are used to connect with the hydrological monitoring instrument to be calibrated. Through these calibration holes, the relative position of the hydrological monitoring instrument and the auxiliary instrument can be accurately determined, so that the two can be accurately matched, providing a positioning reference for subsequent calibration operations.

[0040] Cooperation of rotating parts: the calibration rotating bearing 10 is embedded in the center end of the auxiliary instrument calibration disc 8, and the calibration rotating disc 11 is connected with the calibration rotating bearing 10 through the calibration rotating shaft 12. This structure enables the calibration rotating disc 11 to rotate freely around the calibration rotating bearing 10. When calibrating the hydrological monitoring instrument, the operator can rotate the calibration rotating disc 11 according to actual needs, so as to adjust the positions of the calibration standard rod 15 and the calibration fine adjustment rod 16, so as to correspond to different calibration positions of the hydrological monitoring instrument.

[0041] Fine adjustment and positioning function: the calibration fine adjustment hole 13 on the top plate of the calibration rotating disc 11 can be inserted into a special fine adjustment tool. After the calibration rotating disc 11 is rotated to a general position, the fine adjustment tool is inserted into the calibration fine adjustment hole 13, so that the position of the calibration rotating disc 11 can be finely adjusted to realize higher accuracy calibration. The positioning block 14 is used to lock the calibration rotating disc 11 after it is adjusted to a suitable position, so as to prevent accidental rotation of the calibration rotating disc 11 during calibration, and ensure the accuracy and stability of the calibration result.

[0042] Reference function of the calibration standard rod: the calibration standard rod 15 penetrates the center of the calibration rotating disc 11, which serves as a reference for calibration. During the calibration process of the hydrological monitoring instrument, the calibration standard rod 15 provides a fixed and accurate reference position or size standard for the instrument, so as to ensure that the parameters of the instrument can be adjusted according to this standard.

[0043] Fine calibration of the calibration fine adjustment rod: the calibration fine adjustment rod 16 is embedded on the other side of the calibration standard rod 15. After the calibration rotating disc 11 is rotated and preliminarily positioned, if it is found that there is still a slight deviation in calibration, the calibration fine adjustment rod 16 can be adjusted for fine calibration. The calibration fine adjustment rod 16 can further optimize the accuracy of calibration, so as to make the hydrological monitoring instrument meet higher calibration accuracy requirements.

[0044] In summary, the hydrological monitoring instrument rapid calibration auxiliary instrument realizes rapid and accurate calibration of the hydrological monitoring instrument through the cooperation of various parts, from the basic positioning support to the positioning, rotation and fine adjustment mechanism of the calibration disc, and then to the reference and fine calibration of the calibration rod.

Although the utility model has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific embodiments, and any modification or substitution of the utility model; all technical solutions and improvements within the spirit and scope of the utility model are covered in the scope of the claims of the utility model.
