Problems solved by technology

[0004] The principle of the above-mentioned radar water level gauge is to rely on the feedback wave to measure the level of the liquid level. The parallelism between the lower surface of the microwave feedback system and the liquid level in the water area directly affects its measurement accuracy. In the prior art, it is inconvenient to adjust the above parallelism, which is not conducive to radar In order to solve the problem of labor intensity of installation and maintenance of type water level gauge, the invention provides a measuring device

Embodiment 1

[0018] Such as figure 1 , a measuring device, including a host 5, a microwave feedback system 1, a hoop (6), at least three connecting bolts 4 that are not on the same line and whose axes are in a vertical direction, including a host 5, a microwave feedback system 1. It also includes a hoop 6 and at least three connecting bolts 4 that are not located on the same straight line and whose axes are in the vertical direction. The lower ends of the connecting bolts 4 are all fixedly connected to the microwave feedback system 1. The number of bolt holes matches the number of connecting bolts 4, and each connecting bolt 4 is threadedly connected with a nut 3, the host 5 and the microwave feedback system 1 are connected by connecting bolts 4, and the hoop 6 is fixed on the host 5, And the axis of the hoop 6 is parallel to the lower end surface of the microwave feedback system 1 .

[0019] The microwave feedback system 1 is set at the bottom of the microwave level gauge, and the connec...

Embodiment 2

[0021] The present embodiment is further limited on the basis of embodiment 1: as figure 1 , in order to keep the inclination adjustment part of the present invention in good finish for a long time, the connecting bolts 4 and the nuts 3 are made of stainless steel.

[0022] In order to facilitate the display of the levelness status of the microwave feedback system 1 , a level gauge 2 is also provided on the microwave feedback system 1 .

[0023] In order to enhance the inclination adjustment performance of the present invention, the threads on the connecting bolt 4 and the nut 3 are fine threads.

[0024] In order to prevent the microwave feedback system 1 from shaking under the action of wind or other external forces after the inclination adjustment of the microwave feedback system 1 is completed, which will affect the measurement performance of the present invention, there are two nuts 3 threaded on each connecting bolt 4 , and the nuts 3 threaded on each connecting bolt 4 ...

Abstract

The invention discloses a measuring device which comprises a main unit, a microwave feedback system, a hoop and at least three connecting bolts. The connecting bolts are not positioned in the same straight line, the axes of the connecting bolts are positioned on the vertical directions, the lower ends of the connecting bolts are fixedly connected onto the microwave feedback system, bolt holes are formed in the main unit, a nut is further connected onto each connecting bolt in a threaded manner, and the main unit is in bolted connection with the microwave feedback system by the connecting bolts. The measuring device has the advantages that the length of each connecting bolt between the microwave feedback system and the main unit can be adjusted, so that the levelness of the lower end surface of the microwave feedback system can be adjusted; similarly, the inclination can be roughly adjusted by the aid of the hoop, the hoop brings convenience for mounting the measuring device, accordingly, microwave transmitting and receiving ends of the measuring device are parallel to monitored liquid levels, the intensity of reflected waves which are reflected onto the microwave feedback system can be improved advantageously, the inclination of the microwave transmitting and receiving ends can be adjusted conveniently, and the measuring device has low requirements on mounting support manufacturing and mounting precision.

Description

technical field [0001] The invention relates to the field of natural disaster protection systems, in particular to a measuring device. Background technique [0002] In recent years, flash flood disasters caused by sudden and localized extreme heavy rainfall in my country have caused a large number of casualties, accounting for an increasing proportion of the total number of flood disaster deaths, and incidents of mass death and mass injury have occurred from time to time. Mountain torrent disasters severely restrict the economic development of mountainous and hilly areas, the realization of the goals of getting rid of poverty and becoming rich, building a socialist harmonious society and building a new socialist countryside, which are outstanding problems to be solved urgently in the current work of flood control and disaster reduction in our country. [0003] In the prior art, the monitoring of the liquid level in the water area is mostly done by automatic measurement of on...
