[0022] The present invention will be further described below with reference to specific embodiments. These specific embodiments are further explanations of the principle of the present invention and are not intended to limit the present invention in any way. Any technology that is the same as or similar to the present invention does not exceed the protection scope of the present invention.

[0023] See Figures 1-3 This utility model provides an auxiliary device for convenient measurement of water-filled ditches. The auxiliary device includes a square tube kit, a circular level 3, a spring clip 4, and a ring spring 7.

[0024] The square tube kit includes a first hollow square tube 1 and a second hollow square tube 2. Both the first hollow square tube 1 and the second hollow square tube 2 are aluminum alloy hollow square tubes with a wall thickness of 1mm. There is one first hollow square tube 1, and its length is 2.2 times the length of the second hollow square tube 2. The cross-sectional dimensions of the first hollow square tube 1 are 50mm*25mm, etc. The specific dimensions of this cross-section are adjusted according to the length of the first hollow square tube 1. However, considering the weight of the material and the strength of its connection, the length of the first hollow square tube 1 shall not exceed 6m. For example, if the length of the first hollow square tube 1 is 5m, its cross-sectional dimensions are 50mm*25mm. For every 1m increase or decrease in length, the cross-sectional length increases or decreases by 10mm and its width increases or decreases by 5mm. However, its minimum cross-sectional dimension is not less than 30mm*15mm, and the minimum length of the first hollow square tube is not less than 3m. Two second hollow square tubes 2 are provided, and the length and width of the cross-section of the second hollow square tube 2 match the length and width of the cross-section of the first hollow square tube 1. One second hollow square tube 2 is inserted into each end of the first hollow square tube 1, and the first hollow square tube 1 and the two second hollow square tubes 2 are connected to form an "I" structure. Spring buckles 4 and plastic locking washers 6 are provided at the connection points between the first hollow square tube 1 and the second hollow square tube 2 to ensure that the second hollow square tube 2 is stable in position and will not detach when it is pulled out for use. The plastic locking washers 6 are 1mm thick and are arranged around the openings of both ends of the first hollow square tube 1.

[0025] The first hollow square tube 1 has a central hole 5 in the middle, which is used to insert the support rod of the RTK mobile station. The central hole 5 is equipped with a ring spring 7, which holds the support rod of the RTK mobile station in place to ensure that it is perpendicular to the ground.

[0026] The first hollow square tube 1 has a circular slot at each end. The second hollow square tube 2, inserted into the first hollow square tube 1, has a spring clip 4 at one end. When the second hollow square tube 2 is extended to its maximum spacing, the spring clip 4 engages with the corresponding circular slot in the first hollow square tube 1, ensuring that the second hollow square tube 2 will not fall off when the maximum spacing is reached. The two circular slots on both sides of the first hollow square tube 1 are symmetrically arranged. The circular slots on both sides of the first hollow square tube 1 match the spring clip 4 at the end of the second hollow square tube 1.

[0027] Two second hollow square tubes 2 are each provided with a circular level 3 at the end away from the first hollow square tube 1. The two circular levels 3 on the two second hollow square tubes 2 are centered and the two circular levels 3 allow the RTK mobile station to remain perpendicular to the measurement position during operation by the user of the auxiliary device.

[0028] In use, the two second hollow square tubes of the auxiliary device extend out, and the support rod of the RTK mobile station is inserted into the central hole 5 of the first hollow square tube 1. The annular retaining spring 7 inside the first hollow square tube 1 at the central hole 5 locks the support rod of the RTK mobile station to reduce its shaking. By adjusting the length of the second hollow square tubes 2 at both ends of the first hollow square tube 1, the auxiliary device can adapt to various widths of water channel measurement tasks to suit the on-site measurement conditions. The circular level 3 at both ends of the second hollow square tube 2 is aligned by the measuring personnel at both ends so that the support rod of the RTK mobile station can be perpendicular to the bottom of the water channel to ensure measurement accuracy.
