Description

Technical Field

[0001] The utility model relates to the technical field of hydrological monitoring, in particular to a radar water level meter fixing device. Background Art

[0002] In hydrological monitoring, radar water level gauges are often used to monitor water levels. The principle of radar water level gauges is to use a water level sensor antenna to send pulses to the water surface, and the water surface then reflects the pulses back. When sending pulses to the water surface, the pulses need to be perpendicular to the water surface. Therefore, in order to prevent the radar water level gauge from shaking and causing the pulse direction to deviate, a fixing device is often used to fix the radar water level gauge in the related art.

[0003] The fixing device in the related art is directly fixed to the water level meter. Once the fixing device is fixed in the selected fixed position, the water level meter cannot be adjusted. The installation environment of different waters is also different. If the geographical location is uneven, it is easy for the pulse of the fixed water level meter to be not perpendicular to the water surface. In this case, it is necessary to re-select a suitable fixing position so that the pulse emitted by the fixed water level meter is perpendicular to the water surface.

[0004] Therefore, once the fixing device in the related technology is fixed, the water level meter cannot be debugged well, which leads to stricter requirements on the fixing environment and fewer compatible fixed environments. If the fixing position is not selected well, the position monitoring of the water level by the fixed water level meter will be inaccurate, and a lot of time will be required to re-select the fixing position, which takes a lot of time and reduces the monitoring efficiency.

The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] Existing water conservancy monitoring requires the use of radar water level meters, which are electronic devices that use electromagnetic waves to detect targets. Their main functions are to carry out water conservancy monitoring, sewage treatment, and flood prevention warnings. When using radar water level meters for monitoring, the pulses emitted by the radar water level sensor antenna of the radar water level meter need to be set perpendicular to the water surface, so that accurate measurement data can be obtained.

[0032] Generally, a fixing device is used to fix the position of the radar water level meter, and the fixing device needs to be fixed around the water area. However, in different waters, the installation environment of the fixing device is different. It is easy for the radar water level meter to emit pulses that are not perpendicular to the water surface after the fixing device is fixed, which will affect the monitoring accuracy.

[0033] The utility model provides a radar water level meter fixing device for fixing the position of the radar water level meter. In one embodiment, please refer to Figure 1 and Figure 2 The radar water level meter fixing device includes a mounting frame 1 and a mounting seat 2, wherein the mounting frame 1 is fixedly arranged and serves as a supporting bracket of the water level meter.

[0034] The mounting seat 2 includes a mounting frame 21 and a mounting platform 22. The mounting seat 2 is connected to the mounting frame 1 and can rotate relative to the mounting frame 1 around a first axis. The mounting platform 22 is used to install the water level gauge. The mounting platform 22 is connected to the mounting frame 21 and can rotate relative to the mounting frame 21 around a second axis. The first axis and the second axis are located in a predetermined plane, and the first axis is perpendicular to the second axis. Please refer to Figure 1 , Figure 1 The direction X in the diagram is parallel to the first axis, and the direction Y is parallel to the second axis. It should be noted that the predetermined plane in the present application refers to a horizontal plane.

[0035] The water level gauge can be installed by setting the installation platform 22, and the water level gauge can be rotated around the second axis by rotating the installation platform 22 and the installation frame 21, that is, the pulse of the water level gauge can be rotated around the second axis, and the water level gauge can be rotated around the first axis by setting the installation frame 21 to rotate around the first axis relative to the installation frame 1. In this way, the angle of the water level gauge can be adjusted very conveniently, so that it can be rotated and adjusted around the first axis and the second axis, and the first axis and the second axis are located on the horizontal plane. By adjusting the water level gauge, the pulse emitted by the water level gauge can be perpendicular to the water surface, ensuring the accuracy of monitoring.

[0036] By adjusting the rotation of the water level meter around the first axis and the second axis, the direction of the pulse emitted by the water level meter can be adjusted so that it is finally perpendicular to the water surface. In this way, the mounting frame 1 can be installed without being affected by the environment when it is installed and fixed, and can be installed in any environment. Even if the pulse of the water level meter is not perpendicular to the water surface after the mounting frame 1 is installed and fixed, the pulse emission direction can be adjusted to be perpendicular to the water surface by adjusting the water level meter. Such a setting is not only conducive to the mounting frame 1 adapting to various installation environments, but also avoids the problems of low installation efficiency and low monitoring efficiency caused by reselecting the fixing position.

[0037] In one embodiment, see Figure 1 and Figure 2 The mounting frame 1 has a first mounting plate 123 , the mounting frame 21 includes a connecting plate 211 and a side plate 212 , the mounting platform 22 has a platform plate 221 , the connecting plate 211 is rotatably connected to the first mounting plate 123 , and the platform plate 221 is rotatably connected to the side plate 212 .

[0038] It should be noted that the first mounting plate 123 is disposed perpendicular to the first axis, and the connecting plate 211 is parallel to the first mounting plate 123 when being rotatably connected to the first mounting plate 123 .

[0039] The connecting plate 211 is provided with two side plates 212, which are completely identical and spaced apart, and are parallel to each other on the same side of the connecting plate 211. More specifically, the two side plates 212 are located at the end of the connecting plate 211 facing away from the end of the connecting plate 211 connected to the first mounting plate 123. Accordingly, a platform plate 221 is provided on the mounting platform 22 corresponding to each side plate 212.

[0040] In a specific embodiment, a first adjustment groove 1231 is opened around the first axis on the first mounting plate 123, and a first fastener (not shown in the figure) is provided on the connecting plate 211. The first fastener can be inserted into the first adjustment groove 1231, and the connecting plate 211 can be fixed or rotated relative to the first mounting plate 123 through the loose fit of the fastener.

[0041] The connecting plate 211 can be rotatably connected to the first mounting plate 123 via structures such as bearings. In order to enable the connecting plate 211 to be fixed in position after being rotated by a predetermined angle relative to the first mounting plate 123, a first fastener needs to be provided to enable the connecting plate 211 to switch between free rotation and fixed states relative to the first mounting plate 123.

[0042] Specifically, the first fastener preferably adopts a screw-nut matching structure. For example, the screw can be passed through the connecting plate 211, and the threaded end of the screw is passed through the first adjustment groove 1231, and its end needs to extend out of the first adjustment groove 1231, and the extended part is threadedly matched with the nut. When the screw and the nut are tightened, the first mounting plate 123 and the connecting plate 211 can be clamped so that the two are not easy to move relative to each other. When the screw and the nut are loosened, the connecting plate 211 can rotate relative to the first mounting plate 123.

[0043] Of course, the first fastener is not limited to the combination of a screw and a nut, and any structure that can achieve a tight fit and enable the connection plate 211 and the first mounting plate 123 to be relatively fixed or rotated can be used.

[0044] In a preferred embodiment, two spaced first adjustment grooves 1231 are provided on the first mounting plate 123, and the two first adjustment grooves 1231 are both opened around the first axis. The two first adjustment grooves 1231 are preferably symmetrically arranged relative to the first axis. By providing two first adjustment grooves 1231 and cooperating with the above-mentioned first fasteners, the connecting plate 211 does not need to be rotatably connected to the first mounting plate 123 through structures such as bearings, but only needs to be respectively inserted into the two first adjustment grooves 1231, so that the connecting plate 211 and the first mounting plate 123 can be rotatably connected through the two first fasteners.

[0045] In a specific embodiment, the side panel 212 and the platform panel 221 are rotatably connected via a rotating shaft, a second adjustment groove 2121 is opened on the side panel 212 around a second axis, a second fastener is provided on the platform panel 221, and the second fastener can be inserted into the second adjustment groove 2121. The platform panel 221 can be fixed or rotated relative to the side panel 212 through the loose and tight fit of the second fastener.

[0046] The cooperation between the second adjustment groove 2121 and the second fastener in this embodiment has the same effect as the cooperation between the first adjustment groove 1231 and the first fastener described above, and both can achieve the fixation or rotation of the relative position between the two plates by adjusting the tightness of the second fastener.

[0047] It should be noted that the second fastener in this embodiment is preferably a screw and nut matching structure, and its specific matching method and connection method are the same as the above-mentioned first fastener, which will not be repeated here.

[0048] In one embodiment, see Figure 1 and Figure 2 The installation platform 22 also includes a fixing platform 222 connected to the platform plate 221. The fixing platform 222 can fix the water level meter. A protective cover 223 is also provided on the fixing platform 222. The protective cover 223 can cover the water level meter to protect the water level meter from being damaged by external collisions. The protective cover 223 can also protect the water level meter from being damaged by rain on rainy days, so that the water level meter can work normally on rainy days.

[0049] In one embodiment, the mounting frame 1 includes a support member 11 and a mounting arm 12 connected to the support member 11. The support member 11 and the mounting arm 12 can be configured as a hollow structure to allow cables of structures such as a water level meter to pass through.

[0050] The first mounting plate 123 is fixedly connected to one end of the mounting arm 12 away from the supporting member 11 , and the mounting seat 2 is rotatably connected to the first mounting plate 123 via the connecting plate 211 .

[0051] The mounting arm 12 is configured to be rotatable relative to the support member 11 about a third axis, the third axis being perpendicular to the first axis and the second axis. Figure 1 As shown, direction Y is parallel to the direction of the third axis. By setting the mounting arm 12 to be rotatable around the third axis, the water level gauge on the mounting arm 12 can also be rotated around the third axis, so that the water level gauge can be rotated in the horizontal plane so that it can change the water surface position to be detected.

[0052] In a specific embodiment, the mounting frame 1 also includes a mounting assembly 13, the mounting assembly 13 includes a first hinged portion 132 and a second hinged portion 133, the first hinged portion 132 is fixedly connected to the top end of the support member 11, and a second mounting plate is also provided on the mounting arm 12, the second mounting plate is fixedly connected to one end of the mounting arm 12 away from the first mounting plate 123, the second hinged portion 133 is connected to the second mounting plate, and the first hinged portion 132 and the second hinged portion 133 are hingedly connected to realize the rotation between the mounting arm 12 and the support member 11.

[0053] It should be noted that the mounting assembly 13 also includes a mounting platform 131 fixedly connected to the support member 11, one end of the second mounting plate is arranged close to the mounting platform 131, and an adjustment plate 1241 is also provided at this end of the second mounting plate, and the adjustment plate 1241 can be attached to the mounting platform 131.

[0054] A third adjusting groove 1311 is penetrated on the mounting platform 131 around the third axis, and a third fastener is provided on the adjusting plate 1241. The third fastener is penetrated in the third adjusting groove 1311. The adjusting plate 1241 can be fixed or rotated relative to the mounting platform 131 through the loose and tight fit of the third fastener.

[0055] The cooperation between the third fastener and the third adjustment groove 1311 is similar to the cooperation between the first adjustment groove 1231 and the first fastener mentioned above, and the effect of the cooperation is also the same, both of which realize the relative fixation or rotation between the two rotatably connected structures through the tightness of the fastener.

[0056] Specifically, the third fastener is preselected as a structure composed of a screw and a nut, and the setting method between the screw and the nut of the third fastener is similar to the setting method of the first fastener. The screw is passed through the adjustment plate 1241 and the third adjustment groove 1311, and the adjustment plate 1241 is fixed or rotated relative to the mounting platform 131 by tightening and loosening the nut and the screw, thereby achieving relative fixation or rotation of the mounting arm 12 relative to the support member 11.

[0057] In a specific embodiment, a reinforcing arm 121 is further provided on the mounting arm 12, and both ends of the reinforcing arm 121 are respectively fixedly connected to the mounting arm 12 and the second mounting plate.

[0058] In order to ensure the normal operation of the water level meter, a chassis 14 can be provided on the support 11, and a power supply can be provided inside the chassis 14, and the power supply is used to power the water level meter. In order to ensure the power supply, a solar bracket 122 can be fixedly connected to the reinforcing arm 121, and a solar panel is placed on the solar bracket 122, and the solar panel is electrically connected to the power supply to charge the power supply. In addition, a rain gauge platform 15 is also provided on the chassis 14 for installing a rain gauge.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
