[0002] The microwave level switch is a solid level switch using microwave transmission and reception. The microwave level switch is usually a matched instrument, one end of which is a transmitting end responsible for microwave signal transmission, and the other end is a receiving end responsible for microwave signal collection and output. The instrument is installed in pairs at the position to be monitored. When there is no material at the monitoring position, the receiving end outputs a "no material" signal; when there is material at the monitoring position, the receiving end outputs a "material" signal. The state of the output signal can be set on site to high or low alarm.

[0003] The microwave level switch is an ultra-precision instrument that needs to be perfectly matched with the on-site tank. If the matching is not perfect, unpredictable problems such as material blockage, probe false alarm, and abnormal probe operation may occur.

[0032] In order to solve the problem that the existing microwave level switch is difficult to test before leaving the factory, the utility model provides a microwave intelligent detection device, comprising: a control console configured to supply power to the transmitting end and the receiving end; a first support assembly configured to support the transmitting end; a second support assembly located on the transmission path of the transmitting end and configured to support the receiving end so that the receiving end can receive the microwave emitted by the transmitting end; a shielding assembly located between the first support assembly and the second support assembly and configured to shield the microwave emitted by the transmitting end towards the receiving end.

[0033] The microwave intelligent detection device of some embodiments of the present disclosure will be described below through specific examples.

[0034] As shown in Figure 1 The microwave level switch includes a transmitting end 11 and a receiving end 12, the transmitting end 11 is used for transmitting microwave signals, and the receiving end 12 can receive the microwave signals transmitted by the transmitting end 11, analyze and output the level information.

[0035] The microwave intelligent detection device provided by the utility model includes a console, a first support assembly 2, a second support assembly 3 and a shielding assembly 4, the console is used for supplying power to the transmitting end 11 and the receiving end 12, and the transmitting end 11 and the receiving end 12 can work normally. The first support assembly 2 is used for supporting the transmitting end 11, so that the transmitting end 11 can be placed horizontally. The second support assembly 3 is located on the transmission path of the transmitting end 11 and is used for supporting the receiving end 12, so that the receiving end 12 can receive the microwave signal emitted by the transmitting end 11. The shielding assembly 4 is located between the first support assembly 2 and the second support assembly 3 and is used for shielding the microwave signal emitted by the transmitting end 11 towards the receiving end 12 by simulating the material. First, the first support assembly 2 and the second support assembly 3 are moved to a suitable distance, so that the distance between the transmitting end 11 and the receiving end 12 is equal to the installation distance of the customer site, so as to simulate the site working condition, and then the shielding assembly 4 is adjusted. When the shielding assembly 4 shields the microwave signal emitted by the transmitting end 11 towards the receiving end 12, it is tested whether the receiving end 12 can normally output the material level information with material; when the shielding assembly 4 moves away or does not shield the microwave signal emitted by the transmitting end 11 towards the receiving end 12, it is tested whether the receiving end 12 can normally output the material level information without material, so as to test whether the microwave material level switch can work normally.

[0036] In some examples, the microwave intelligent detection device further comprises a track 5, the track 5 is parallel to the transmission direction of the transmitting end 11, and at least one of the first support assembly 2 and the second support assembly 3 is in sliding connection with the track 5. The first support assembly 2 and the second support assembly 3 can move along the track 5 to adjust the distance, so that the receiving end 12 located on the second support assembly 3 can always be aligned with the transmitting end 11 located on the first support assembly 2, and the difficulty of aligning the transmitting end 11 and the receiving end 12 is reduced.

[0037] The shielding assembly 4 can also be in sliding connection with the track 5, so that the shielding assembly 4 can always be located between the transmitting end 11 and the receiving end 12.

[0038] In some examples, the shielding assembly 4 comprises a base 41 and a shielding plate 42, the shielding plate 42 is in rotary connection with the base 41, the shielding plate 42 can shield the microwave signal emitted by the transmitting end 11 when the shielding plate 42 is rotated above the base 41, and the shielding assembly 4 can avoid the microwave signal emitted by the transmitting end 11 when the shielding plate 42 is rotated to the side of the base 41. Specifically, the height of the base 41 is lower than the height of the transmitting end 11, so that the base 41 does not hinder the receiving end 12 from receiving the microwave signal when the shielding plate is rotated to not hinder the receiving end 12 from receiving the microwave signal. In this way, the shielding assembly 4 can simulate the state of existing material and the state of non-existing material at the same time, and the shielding assembly 4 does not need to be removed, so that the workload of testing is reduced.

[0039] The size of the transmitting end 11 is different for different models, such as height, length, etc. The head of some microwave level switches is large in size and the tail is long due to structural reasons, at this time, the first support assembly 2 can be provided with a support 21 and a support plate 22, which are used to support different parts of the transmitting end 11 to maintain the stability of the transmitting end 11 and always keep it horizontal. For example, the support 21 is used to support the neck of the transmitting end 11, and the support plate 22 is used to support the tail of the transmitting end 11.

[0040] In addition, for different lengths of the transmitting end 11, the distance between the support 21 and the support plate 22 can be moved so that the support 21 and the support plate 22 can reliably support the transmitting end 11. For example, the support 21 and the support plate 22 are both in sliding connection with the track 5.

[0041] In some examples, at least one of the support 21 and the support plate 22 is provided as a lifting structure. For example, the support 21 and the support plate 22 are both provided as a lifting structure, or the support 21 is provided as a lifting structure, or the support plate 22 is provided as a lifting structure. In addition, the second support assembly 3 can also be provided as a lifting structure. For example, the lifting structure is a screw lifting mechanism, a pneumatic cylinder lifting mechanism, etc. After the support 21, the support plate 22 and the second support assembly 3 are provided as a lifting structure, the adaptability of the first support assembly 2 and the second support assembly 3 can be improved to adapt to different height sizes of the transmitting end 11 and the receiving end 12.

[0042] The console includes a controller configured to control whether to supply power to the transmitting end 11. When the transmitting end 11 needs to emit a microwave signal, the controller is used to control the power supply to the transmitting end 11 at any time to cooperate with the detection. In some examples, the controller can be a wireless remote controller to realize remote control of whether to supply power to the transmitting end 11; or the controller is provided as a wired control switch.

[0043] For example, the controller is provided at the shielding assembly 4. After the position adjustment of the transmitting end 11 and the receiving end 12 is completed, the worker only needs to adjust whether the shielding assembly 4 shields the microwave signal at the shielding assembly 4 and control the controller, so as to complete the detection of the microwave level switch, without the worker walking back and forth between the workbench and the shielding assembly 4, thereby improving the efficiency of the detection work.

[0044] In addition, the internal current control of the console increases the 220V and 24V wiring modes to adapt to microwave level switches of different voltage levels, and the console is equipped with a double control switch to prevent electric shock accidents. The controller can separately control whether the 220V and 24V power sources are put into work.

[0045] In summary, the working principle of the utility model is as follows:

[0046] Firstly, the transmitting end 11 is placed on the first support assembly 2, and the receiving end 12 is placed on the second support assembly 3, so that the microwave signal emitted by the transmitting end 11 can be received by the receiving end 12. Then, the first support assembly 2 and the second support assembly 3 are moved to a suitable distance, so that the distance between the transmitting end 11 and the receiving end 12 is equal to the installation distance of the customer site, to simulate the field working condition, and then the shielding assembly 4 is adjusted. When the shielding plate 42 is rotated above the base 41, the shielding plate 42 can shield the microwave signal emitted by the transmitting end 11, and it is tested whether the receiving end 12 can normally output the material level information with material; when the shielding plate 42 is rotated to the side of the base 41, the shielding assembly 4 can avoid the microwave signal emitted by the transmitting end 11, and it is tested whether the receiving end 12 can normally output the material level information without material, so as to test whether the microwave material level switch can work normally.

[0047] Thus far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
