DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 An RTK measuring device for electric power engineering surveying and mapping includes a support rod 1, a base 2 is fixedly installed on the upper end of the support rod 1, a receiver body 3 is fixedly installed on the upper surface of the base 2, an annular groove is opened on the upper surface of the base 2, an annular protection frame 4 is inserted in the annular groove through an elastic component, the elastic component includes two mounting blocks symmetrically fixedly installed on the annular protection frame 4 and two spring rods 12 respectively fixedly installed on the two mounting blocks, one end of the two spring rods 12 is fixedly connected to the base 2, the annular protection frame 4 can be vertically slidably installed in the annular groove through the spring rods 12, and when the annular protection frame 4 is inserted in the annular groove, the spring rods 12 are in a compressed state.

[0022] A mounting cavity 5 is provided inside the base 2, and a cylindrical groove 6 is provided on the bottom wall of the mounting cavity 5. A rectangular hole 7 is symmetrically provided between the cylindrical groove 6 and the annular groove. A cylinder 9 is vertically slidably installed in the cylindrical groove 6 through a telescopic spring 8. Limit rods 10 are horizontally slidably installed in the two rectangular holes 7. Limit holes are symmetrically provided on the surface of the annular protection frame 4. One end of the two limit rods 10 is respectively inserted in the two limit holes. A transmission assembly for driving the two limit rods 10 to move relative to each other is provided on the cylinder 9. A counterweight ball 11 is placed in the mounting cavity 5, and the counterweight ball 11 is located directly above the cylinder 9. A pulling assembly for pulling the cylinder 9 to move vertically downward is provided on the support rod 1. The transmission assembly includes two support rods 13 rotatably installed at one end of the two limit rods 10 respectively and two connecting blocks 14 symmetrically fixedly installed at the lower end of the cylinder 9. The ends of the two support rods 13 away from the limit rods 10 are rotatably connected to the two connecting blocks 14 respectively;

[0023] A rectangular sliding hole is provided on the surface of the support rod 1, and a moving hole connected to the sliding hole is provided through the bottom wall of the cylindrical groove 6. The pulling assembly includes a moving rod 15 vertically slidably installed in the moving hole and a pull rod 16 fixedly installed at the lower end of the moving rod 15. The pull rod 16 is slidably installed in the sliding hole, and the upper end of the moving rod 15 is fixedly connected to the lower end of the cylinder 9;

[0024] When installing the RTK measuring device, the support rod 1 is vertically inserted into the soil, and then the annular protection frame 4 is vertically inserted into the annular groove, and then the pull rod 16 is vertically pulled downward to drive the moving rod 15 to move vertically downward, and then the cylinder 9 is driven to move vertically downward through the moving rod 15, and the telescopic spring 8 is compressed until the upper end of the cylinder 9 is flush with the bottom of the installation cavity 5. In the process of vertical downward movement of the cylinder 9, the two limit rods 10 are driven to move away from each other through the two support rods 13. When the two limit rods 10 move away from each other, one end is inserted into the limit hole provided on the annular protection frame 4, which plays a role in locking the annular protection frame 4. Then the RTK measuring device is shaken to drive the counterweight ball 11 in the installation cavity 5 to roll to the top of the cylinder 9, thereby suppressing the cylinder 9 and preventing the telescopic spring 8 from returning to its original state.

[0025] When the RTK measuring device topples over during use, the counterweight ball 11 will roll in the mounting cavity 5 in the direction of the topple-over, thereby moving away from the upper end of the cylinder 9, and then, under the action of the elastic force of the telescopic spring 8, will drive the cylinder 9 to move into the mounting cavity 5. During the movement of the cylinder 9, the two limit rods 10 will be driven to approach each other through the two support rods 13, so that one end of the limit rod 10 moves out of the limit hole, releasing the lock on the annular protection frame 4, and then, under the action of the elastic force of the spring rod 12, the annular protection frame 4 will move vertically upward to wrap up the receiver body 3, thereby protecting the receiver body 3, thereby preventing the receiver body 3 from being damaged when the device hits the ground.

[0026] A groove is provided at the upper end of the cylinder 9, and a counterweight ball 11 is placed in the groove. The gravity of the counterweight ball 11 is greater than the elastic force of the telescopic spring 8. The setting of the groove can facilitate the counterweight ball 11 to stay at the upper end of the cylinder 9, thereby suppressing the telescopic spring 8 to restore its original state, and at the same time preventing the counterweight ball 11 from rolling away from the upper end of the cylinder 9 when the support rod 1 is slightly tilted.

[0027] A cover plate 17 is fixedly installed on the upper surface of the base 2 through a supporting column. Absorbing paper is fixedly bonded to the surface of the cover plate 17 and the annular protective frame 4. The cover plate 17 can prevent rainwater and impurities from falling on the receiver body 3. The absorbing paper is a material that can isolate signals. When the annular protective frame 4 wraps up the receiver body 3, its upper end contacts the cover plate 17, so that the receiver body 3 is in a closed space composed of absorbing paper, thereby isolating the signal of the receiver body 3. The operator can judge that the RTK measuring device has tipped over by the disappearance of the signal, and can deal with it as soon as possible to avoid affecting the measurement of the power engineering.

[0028] In the utility model, when the RTK measuring device topples over during use, the counterweight ball 11 will be moved away from the upper end of the cylinder 9, and then, under the action of the elastic force of the telescopic spring 8, the cylinder 9 will be driven to move into the installation cavity 5, and then the two limit rods 10 will be driven to approach each other through the transmission component, and one end of the limit rod 10 will be driven to move out of the limit hole, thereby releasing the lock on the annular protection frame 4, and finally, under the action of the elastic component, the receiver body 3 will be wrapped up by the annular protection frame 4 to protect the receiver body 3, thereby preventing the receiver body 3 from being damaged when the device hits the ground.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
