[0030] Figure 1Figure 1 is a schematic diagram of the installation position of the 3D radar level meter in the prior art, in which reference numeral 60 represents a 3D radar level meter (also referred to as a radar level scanner, such as model ULM-3D-5), reference numeral 70 represents an instrument flange, and reference numeral 80 represents a mounting short pipe. The disadvantages of the installation position are described in the background section, paragraph 3.

[0031] Figure 1 is a schematic diagram of the installation position of the 3D radar level meter in the prior art, in which reference numeral 60 represents a 3D radar level meter (also referred to as a radar level scanner, such as model ULM-3D-5), reference numeral 70 represents an instrument flange, and reference numeral 80 represents a mounting short pipe. The disadvantages of the installation position are described in the background section, paragraph 3. Figure 2 The utility model provides: a 3D radar level meter installation device for silo. The top plate of the silo (specifically, a coal distribution silo, also referred to as a material silo) is provided with a mounting hole 401 (also referred to as a counterbore), and the 3D radar level meter 3 (also referred to as a radar level scanner, such as model ULM-3D-5) is placed on the inner side of the silo through the mounting hole 401. The 3D radar level meter 3 is used to measure the distribution of the material surface in the silo (including information such as the volume, weight, and inventory of the material). The installation device of the application comprises a counterbore cover plate 1 and at least one screw rod 2. The counterbore cover plate 1 is located on the outer side of the silo, and the counterbore cover plate 1 covers the mounting hole 401, thereby playing a sealing role. One end of the screw rod 2 is connected to the counterbore cover plate 1, and the other end of the screw rod 2 is connected to the body flange 301 at the bottom of the 3D radar level meter 3. The connection here can be detachable or fixed, and the embodiment does not limit it. In use, the two ends of the screw rod 2 are connected to the counterbore cover plate 1 and the body flange 301 respectively, and then the installation device with the 3D radar level meter 3 is placed in the mounting hole 401 of the silo. At this time, the counterbore cover plate 1 covers the mounting hole 401 completely, so that the counterbore cover plate 1 can prevent coal on the belt from falling and clogging the 3D radar level meter 3, thereby avoiding measurement errors. At the same time, since the 3D radar level meter 3 is located in the counterbore, the installation position of the 3D radar level meter 3 is lowered, thereby avoiding tripping of pedestrians and improving the safety of use. Preferably, the counterbore cover plate 1 (such as the position of the side wall) is provided with a through hole, and / or the top plate of the silo is provided with a through hole. The 3D radar level meter is connected to an external device through a digital communication cable that passes through any one or more through holes. It should be noted that the number of through holes is determined according to the number of digital communication cables. The external device refers to a device other than the 3D radar level meter installation device, such as a background server. The length of the screw rod 2 is 1-1.30 m, such as 1 m, 1.10 m, 1.20 m, and 1.30 m. The length of the screw rod 2 is best when it is 1.2 m, so that the installation position of the 3D radar level meter can be lowered, and the lower part of the installation position can be kept away from obstacles (referring to the steel structure support 1 m below the top of the silo 4), thereby solving the problem of the measurement blind area. It should be noted that Figure 2 In the figure, the letter H represents the sinking depth of the 3D radar level meter caused by the installation position of the application compared with the installation of the 3D radar level meter on the top of the silo in the prior art. The actual sinking depth is determined by the actual length of the screw rod 2. Referring to Figure 3As shown in actual field use, the top plate of the silo needs to be provided with two mounting holes 401 for mounting two sets of 3D radar level meter mounting devices, and the two sets of mounting devices are distributed on both sides of the center line of the silo, so that the measurement ranges of the two sets of mounting devices contain the entire silo, and the basic material level conditions of the material distribution in the entire silo can be reflected.

[0032] Referring to Figure 4 As shown, all the 3D radar level meters are connected in parallel through digital communication cables, and then connected to the 3D centralized controller through the RS485 conversion module, and the 3D imaging or volume, mass and other information is displayed through the background software, so as to realize the functions of volume, weight, inventory measurement, material level automatic interlocking control and the like of the material in the silo.

[0033] A plurality of through holes (not shown in the figure) are uniformly arranged on the body flange 301, each of which is matched with the screw rod 2, so that at least one screw rod 2 can be installed on the periphery of the 3D radar level meter 3, and the specific use of several through holes can be set according to the actual needs on site, which is not limited in the embodiment.

[0034] In order to make the 3D radar level meter 3 in the silo, the diameter of the body flange 301 is smaller than the diameter of the mounting hole 401, that is, the widest part of the 3D radar level meter 3 can pass through the mounting hole 401 to enter the silo. It should be noted that for the Limak 3D radar level meter 3, a 500mm mounting hole 401 is provided in the top plate of the silo to meet the actual use.

[0035] In order to prevent the 3D radar level meter 3 from tilting, four screw rods 2 are preferably used to connect the body flange 301, that is, four screw rods 2 are installed around the 3D radar level meter 3, so that the 3D radar level meter 3 can be kept stable and the measurement accuracy can be kept.

[0036] In order to facilitate disassembly and assembly of the device, the screw rod 2 and the counterbore cover plate 1 are detachably connected, such as fixing one end of the screw rod 2 on the counterbore cover plate 1 through a nut, and the screw rod 2 and the body flange 301 are detachably connected, such as fixing the other end of the screw rod 2 on the body flange 301 through a nut.

[0037] In order to prevent the staff from working on the silo platform (referring to the top of the silo surrounded by the railing) and colliding with the counterbore cover plate 1, the counterbore cover plate 1 and the silo (specifically the top of the silo 4) are detachably connected, such as through common connecting members such as bolts, so that the counterbore cover plate 1 cannot move horizontally, so that the 3D radar level meter 3 cannot shake.

[0038] In order to improve the stability of the installation device, the installation device further comprises a safety rope (not shown in the figure). In the embodiment, the lower surface (preferably at the central position) of the counterbore cover plate 1 is provided with a pull ring (not shown in the figure). One end of the safety rope is tied to the body flange 301 of the 3D radar level meter 3, and the other end of the safety rope is tied to the pull ring on the counterbore cover plate 1, so that the accidental situation caused by the loosening of the nut on the screw rod 2 can be avoided.

[0039] In order to keep the counterbore cover plate 1 clean, the upper surface of the counterbore cover plate 1 is coated with a self-cleaning coating, so that the impurities such as coal dust and dust adhered to the counterbore cover plate 1 can be reduced.

[0040] In order to facilitate the removal of the installation device from the silo, the upper surface of the counterbore cover plate 1 is provided with a handle (not shown in the figure), which can be manually lifted or lifted by means of an electric hoist or other lifting device.

[0041] It is known from common technical knowledge that the utility model can be realized by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above-mentioned disclosed embodiments are only examples and are not the only ones. All changes within the scope of the utility model or within the scope equivalent to the utility model are included in the utility model.
