Detailed implementation manners

[0072] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the attached Figure 1 - attached Figure 10 , and it is obvious that the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0073] The first embodiment of the present application discloses a 3D radar level gauge. Refer to Figure 1 , as an implementation manner of the 3D radar level gauge, the 3D radar level gauge may include a protective housing 100, and the protective housing 100 may include a detection cover 110, a protective cover 120 and a protective cover plate 130. Among them, the detection cover 110 is transparently arranged, the protective cover 120 is detachably connected to the detection cover 110 by bolts, and the protective cover plate 130 is detachably connected to the protective cover 120 by bolts. A display instrument, a host computer, a meter head, etc. may be connected to the protective cover plate 130.

[0074] Refer to Figure 2 , the 3D radar level gauge may further include a mounting frame 700, a receiving frame 200, a drive assembly 300, a swing frame 400, a swing assembly 500 and a probe 600.

[0075] Among them, a barrel inner mounting plate 210 is rotatably connected to the receiving frame 200. The barrel inner mounting plate 210 is mounted on one end of the protective cover 120 away from the protective cover plate 130 through bolts, and the mounting frame 700 is placed inside the protective cover 120. The mounting frame 700 can mount components such as circuit boards and controllers, and wires can pass through the protective cover plate 130 to be connected to related external components. The driving assembly 300 is mounted on the mounting frame 700 and is used to drive the horizontal rotation of the receiving frame 200. The swing frame 400 is rotatably connected to the receiving frame 200; the swing assembly 500 is mounted on the mounting frame 700 and is used to drive the swing of the swing frame 400. The probe 600 is placed inside the detection cover 110 and is mounted on the swing frame 400.

[0076] The driving assembly 300 may include a driving motor 310, a driving main gear 330, and a driving driven gear 340; among them, the driving motor 310 is mounted on the mounting frame 700, and the output shaft passes through the mounting frame 700; the driving main gear 330 is coaxially and fixedly connected to one end of the output shaft passing through the mounting frame 700; the driving driven gear 340 is mounted on the receiving frame 200 and meshes with the driving main gear 330, and the diameter of the driving main gear 330 is smaller than the diameter of the driving driven gear 340.

[0077] The swing assembly 500 may include a swing motor 530, a swing main bevel gear 510, and a swing driven bevel gear 520. The swing motor 530 is mounted on the mounting frame 700, and the output shaft of the swing motor 530 passes through the mounting frame 700 and is rotatably connected to the driving driven gear 340 through a bearing. The swing main bevel gear 510 is coaxially and fixedly connected to one end of the output shaft of the swing motor 530 passing through the mounting frame 700; the swing frame 400 is rotatably connected to the receiving frame 200 through a rotating shaft, the swing driven bevel gear 520 is coaxially and fixedly connected to the rotating shaft, and the swing main bevel gear 510 meshes with the swing driven bevel gear 520. When the swing driven bevel gear 520 rotates, it will drive the swing frame 400 to swing.

[0078] In addition, a limit frame 540 is coaxially and fixedly connected to the output shaft of the swing motor 530, and a limit switch 550 is also mounted on the receiving frame 200; the limit frame 540 rotates with the output shaft of the swing motor 530, and the limit switch 550 rotates with the receiving frame 200; when the second limit frame 540 abuts against the second limit switch 550, the swing motor 530 and / or the driving motor 310 stops operating; the setting of the limit frame 540 and the limit switch 550 limits the flipping angle and the horizontal rotation angle of the probe 600.

[0079] The implementation principle of this embodiment is as follows:

[0080] When the driving motor 310 operates, the driving main gear 330 drives the rotation of the driving driven gear 340. The driving driven gear 340 drives the rotation of the receiving frame 200. The receiving frame 200 drives the rotation of the swinging frame 400. The swinging driven bevel gear 520 moves along the swinging main bevel gear 510, thereby realizing the horizontal rotation of the probe 600. When the limiting frame 540 abuts against the limit switch 550, it indicates that the probe 600 has rotated horizontally to the maximum angle, and the driving motor 310 stops operating.

[0081] When the swinging motor 530 operates, the swinging main bevel gear 510 drives the rotation of the swinging driven bevel gear 520. The swinging driven bevel gear 520 drives the rotation of the swinging frame 400, thereby realizing the flipping of the probe 600. When the limiting frame 540 abuts against the limit switch 550, it indicates that the probe 600 has flipped to the maximum angle, and the swinging motor 530 stops operating.

[0082] The probe 600 can flip while rotating horizontally, and the flipping and horizontal rotation of the probe 600 can also be independent of each other.

[0083] Refer to Figure 3 and Figure 4 As another implementation of the 3D radar level gauge, mounting rings 140 are coaxially and fixedly connected to one end of the detection cover 110 and both ends of the protective cover 120. Clamping grooves 141 are formed in the mounting ring 140 of the detection cover 110 and the mounting ring 140 of the protective cover 120 near one end of the protective cover plate 130. Clamping blocks are fixedly connected to the mounting ring 140 of the protective cover 120 near one end of the detection cover 110 and the protective cover plate 130, and the clamping blocks can be clamped in the clamping grooves 141. Mounting rectangular grooves 142 are formed in the mounting rings 140, and mounting ring grooves 143 communicating with the mounting rectangular grooves 142 are also formed in the mounting rings 140 of the detection cover 110.

[0084] Refer to Figure 3 - Figure 5 As shown in

[0085] A hidden groove 132 is formed in the protective cover plate 130. The elastic hidden block 131 is slidably connected to the protective cover plate 130 through the hidden groove 132, and the locking rod 150 passes through the hidden groove 132 and the elastic hidden block 131. A hidden spring 160 is coaxially sleeved on the locking rod 150. The hidden spring 160 is placed in the hidden groove 132 and abuts against the elastic hidden block 131. A nut groove adapted to the locking nut 151 is formed in the elastic hidden block 131, and the locking nut 151 is coaxially and fixedly connected to the locking rod 150. Initially, the end face of the locking nut 151 is flush with the surface of the elastic hidden block 131 and the surface of the protective cover plate 130.

[0086] The implementation principle of this embodiment is as follows:

[0087] When disassembling the protective housing 100, press the elastic hidden block 131 to expose the locking nut 151, and then rotate the locking rod 150 through the locking nut 151 so that the locking block 152 is aligned with the installation rectangular groove 142. Then pull the locking rod 150 so that the locking block 152 disengages from the installation rectangular groove 142, thereby realizing the disassembly of the detection cover 110. Then remove the protective cover 120 to realize the disassembly of the protective housing 100.

[0088] Of course, in order to facilitate the alignment of the locking block 152 with the installation rectangular groove 142, marks can be made on the locking nut 151.

[0089] Furthermore, referring to Figure 6 , the 3D radar level gauge may further include a storage block 133 and a cleaning cloth. Among them, a storage groove can be formed in the side wall of the protective cover plate 130. The storage block 133 is slidably connected to the protective cover plate 130 through the storage groove. A cleaning groove is formed in the storage block 133, and the cleaning cloth can be placed in the cleaning groove. The storage block 133 can be regarded as a drawer. A groove for facilitating the pulling of the storage block 133 can be formed on the outer wall of the storage block 133.

[0090] In order to prevent the storage block 133 from detaching from the protective cover plate 130, a blocking block 134 is rotatably connected to the protective cover plate 130. The blocking block 134 can abut against the protective cover plate 130; a relatively large external force needs to be applied to rotate the blocking block 134.

[0091] Referring to Figure 7 - Figure 9, Further, a rotary joint 801 can be installed on the protective cover plate 130. The rotary end of the rotary joint 801 is rotatably connected to the protective cover plate 130. The fixed end of the rotary joint 801 is provided with a water inlet, which can be connected to an external water supply structure. The rotary end of the rotary joint 801 is communicated with a spiral heat dissipation pipe 802. The spiral heat dissipation pipe 802 is sleeved on the protective cover 120. One end of the spiral heat dissipation pipe 802 close to the rotary joint 801 is communicated with a first solenoid valve 803. The water outlet end of the spiral heat dissipation pipe 802 is arranged close to and facing the detection cover 110, so that the dissipated cooling water flows onto the detection cover 110; the water outlet end of the spiral heat dissipation pipe 802 is communicated with a second solenoid valve 804.

[0092] In order to facilitate the flushing of the entire detection cover 110, a rotary gear ring 805 is rotatably connected to the fixed end of the rotary joint 801 through a face bearing, and teeth are provided on the outer wall of the rotary gear ring 805. An auxiliary plate 806 is installed at the fixed end of the rotary joint 801. A rotary motor 807 is installed on the auxiliary plate 806. The output shaft of the rotary motor 807 is coaxially and fixedly connected with a rotary gear 808. The rotary gear 808 meshes with the outer wall of the rotary gear ring 805; a rotary ring 809 is coaxially and fixedly connected to the water inlet end of the spiral heat dissipation pipe 802. The rotary ring 809 is fixedly connected to the inner wall of the rotary gear ring 805, and the rotary ring 809 is slidably connected to the protective cover 120 along the circumferential direction of the protective cover 120.

[0093] After the first solenoid valve 803 is opened, the dissipated cooling water enters the spiral heat dissipation pipe 802 and exchanges heat with the protective cover 120, thereby reducing the temperature of the related structures inside the protective cover 120 and achieving the heat dissipation effect of the 3D radar level gauge. After the second solenoid valve 804 is opened, the dissipated cooling water can flush the detection cover 110. When flushing the detection cover 110, the rotary motor 807 can be started. The rotary motor 807 drives the rotation of the rotary gear 808, thereby driving the rotation of the rotary gear ring 805. The rotary gear ring 805 drives the movement of the rotary ring 809 to realize the circumferential movement of the rotary ring 809 along the protective cover 120 and the rotation of the spiral heat dissipation pipe 802 to comprehensively clean the detection cover 110.

[0094] It should be noted that the teeth of the rotary gear ring 805 and the rotary gear 808 are not shown, but it does not affect the meshing relationship between the two.

[0095] The second embodiment of the present application discloses a level scanning imaging system. Refer to Figure 10 , The level scanning imaging system can include a 3D radar level gauge fixedly arranged on the top of the silo, a computer and a controller arranged outside the silo. The 3D radar level gauge is connected to the computer and the controller through signal lines respectively. The 3D radar level gauge can send the scanned and measured data to the computer for display; the computer can send an adjustment instruction to the controller, and the controller can control the adjustment of the angle of the 3D radar level gauge.

[0096] The above are all preferred embodiments of the present application, which do not successively limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless specifically described, can be replaced by other equivalent or alternative features with similar purposes. That is, unless specifically described, each feature is only an example of a series of equivalent or similar features.
