Technical Field

[0001] This utility model belongs to the field of folding structure technology, specifically relating to the folding structure of a portable surveying instrument with Beidou positioning. Background Technology

[0002] In the field of marine surveying, the demand for high precision and portability is increasing. BeiDou positioning technology, with its high precision, high reliability, and my country's independent controllability, has been widely applied to various surveying instruments. Portable surveying instruments, such as the JC-CSL01 depth sounder, meet the needs of surveyors to work anytime and anywhere in various complex environments. The JC-CSL01 depth sounder primarily uses a cable to connect the probe to the survey area to measure depth and records data location using BeiDou positioning.

[0003] In existing technologies, when using portable surveying instruments with Beidou positioning, the measuring rod needs to maintain stable measurement, and the measuring probe needs to maintain an appropriate measurement distance from the hull during actual use. This can effectively protect the related measuring components of the probe and ensure the accuracy of the equipment. Therefore, there is a lack of a folding structure at the hull position to assist in supporting the cable or measuring rod. To address this, we propose a folding structure for portable surveying instruments with Beidou positioning. Utility Model Content

[0004] The purpose of this invention is to provide a folding structure for a portable BeiDou positioning surveying instrument to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a folding structure for a portable Beidou positioning surveying instrument, including a fixing sleeve for fixing the surveying rod of the surveying instrument, an extension rod is integrally inclined on one side of the fixing sleeve, and the other end of the extension rod is rotatably connected to a hand support rod through a locking screw assembly, wherein the hand support rod is fixed to the edge of the hull through a clamping plate structure. The fixed sleeve has a hole for the surveying rod to pass through. A surveying rod fixing screw is screwed through one side of the fixed sleeve. An auxiliary sleeve is fitted on the outside of the surveying rod directly below the fixed sleeve. Opposing screws are screwed through both sides of the auxiliary sleeve. A bearing bracket is fixedly installed on the outside of the auxiliary sleeve. A wheel assembly is rotatably installed on the bearing bracket.

[0006] Furthermore, the clamping plate structure includes a positioning plate that is screwed onto the bottom of the handheld support rod. The top of the positioning plate is screwed onto the handheld support rod via a fixing platform. A fixing screw is screwed onto the outer side of the positioning plate. After a washer structure is fitted onto the outer side of the fixing screw, it passes through the inner wall of the fixed hull and is screwed onto the positioning plate.

[0007] Furthermore, cable guards are symmetrically and alternately arranged at the top of the support bracket, wherein the cable guards are fixed by being squeezed and inserted into corresponding holes on the support bracket, and are distributed on both sides at an equal interval of n:n+1.

[0008] Furthermore, the inner wall of the fixing sleeve is symmetrically nested with arc-shaped inner pads.

[0009] Furthermore, a rubber pad structure is fitted at the end positions of both the fixing screw of the surveying rod and the opposing screw.

[0010] Furthermore, the locking screw assembly includes a rod and a nut, and the rod passes through the rotatably connected portion of the hand-held support rod and the extension rod, and is screwed and fixed with the nut, wherein the nut is used to control the rotation or locking of the hand-held support rod and the extension rod by adjusting the tightness.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this solution, the extension rod and handheld support rod, which are correspondingly set on the outside of the surveying instrument pole structure, enable the outward extension of the surveying instrument pole structure. The reinforcement of the fixed structure ensures the stability of the surveying instrument during water depth measurement and guarantees the accuracy of the surveying data. The auxiliary sleeve, which is fixed on the extension rod or the outside of the surveying instrument pole, provides protection against detachment of the surveying probe connecting wires, preventing excessive swaying of the wires during deployment and affecting their use.

[0017] The hand-held support rod 1 is fixed to the edge of the hull via a clamping structure; The clamping structure includes a positioning plate 8 that is screwed onto the bottom of the handheld support rod 1. The top of the positioning plate 8 is screwed onto the handheld support rod 1 via a fixing platform 7. A fixing screw 9 is screwed onto the outer side of the positioning plate 8. After a washer structure 11 is fitted onto the outer side of the rod of the fixing screw 9, it passes through the inner wall of the fixed hull and is screwed onto the positioning plate 8.

[0018] The fixed sleeve 3 has a hole for the surveying rod to pass through. The surveying rod fixing screw 10 is screwed through one side of the fixed sleeve 3. The auxiliary sleeve 4 is sleeved on the outside of the surveying rod directly below the fixed sleeve 3. Opposing screws 13 are screwed through both sides of the auxiliary sleeve 4. A bearing bracket 5 is fixedly installed on the outside of the auxiliary sleeve 4. A wheel assembly structure 6 is rotatably installed on the bearing bracket 5.

[0019] Cable guards 14 are symmetrically and alternately arranged at the top of the support bracket 5. The cable guards 14 are fixed by pressing and inserting into the corresponding holes on the support bracket 5. They are distributed on both sides at an equal distance of n:n+1, and generally a 1:2 ratio is used for the alternate arrangement.

[0020] The inner wall of the fixing sleeve 3 is symmetrically nested with arc-shaped inner pads. The ends of the surveying rod fixing screw 10 and the opposing screw 13 are both fitted with rubber pad structures.

[0021] The locking screw assembly 12 includes a rod and a nut, with the rod corresponding to the part through which the hand support rod 1 and the extension rod 2 are rotatably connected, and is screwed into and fixed with the nut. The nut is used to control the rotation or locking of the hand support rod 1 and the extension rod 2 by adjusting its tightness.

[0022] It should be noted that the screw connection structure referred to in this article is a threaded engagement connection, which includes an external thread corresponding to the outside of the column and an internal thread corresponding to the screw connection position, which cooperate and fix each other to ensure a tight fit between the two.

[0023] The working principle and usage process of this utility model: This type of Beidou positioning portable surveying instrument has a folding structure. When in use, it is equipped with a water depth sounder with basic positioning and fixed points, the reference model being the JC-CSL01 depth sounder. It mainly includes a surveying instrument box structure, a surveying rod, a surveying probe, and a wire structure. In use, one end of the wire is connected to the surveying instrument box structure, and the other end of the wire is fixed to the surveying probe. The surveying probe is placed in the surveying water area, and the water depth of the fixed point area is measured through the Beidou positioning and mapping points of the surveying instrument box and the water conduction and reflection. Data is recorded according to the positioning and mapping points. When using the surveying rod, the wire needs to be passed through the surveying rod and connected to the surveying probe. The surveying probe needs to be fixed to the bottom of the surveying rod. The surveying probe can be directly placed in the water to realize the mapping of the fixed point position. Based on the above description, to provide auxiliary support using the folding structure of this application, the handheld support rod 1 needs to be fixed to the edge of the hull. Specifically, the positioning plate 8 is rotated and fixed to the bottom of the handheld support rod 1 via the fixing platform 7, and is positioned for reference. Figure 1 The state is such that the gasket structure 11 is directly inserted through the reserved space inside the hull by the fixed screw 9 and directly screwed into the positioning plate 8. At this time, the rotation angle of the extension rod 2 and the fixed sleeve 3 is adjusted according to the needs, and locked by the nut structure on the locking screw assembly 12. The surveying rod body is placed directly inside the fixed sleeve 3 and tightened by the surveying rod fixing screw 10. The auxiliary sleeve 4 is placed on the top or bottom of the surveying rod for the second time, and the opposing screw 13 is tightened until it touches the outside of the surveying rod for fixing. It is used to store the surveying probe connecting wire. It should be noted that the connecting wires on the surveying rod need to be arranged along the staggered gap on the cable guard 14 and prevented from being on the rollers of the wheel assembly structure 6 for easy storage and wire laying. The auxiliary sleeve 4 can also be directly sleeved on the outside of the extension rod 2 for auxiliary fixing of the extension wire. When it is not necessary to set up the surveying rod, the wire can be directly placed on the wheel assembly structure 6 and passed through the fixing sleeve 3 for auxiliary apex wire laying.

[0024] As can be seen from the above working process, in this solution, the extension rod 2 and the handheld support rod 1, which are respectively set on the outside of the surveying instrument pole structure, realize the outward extension of the surveying instrument pole structure. In addition, the stability of the surveying instrument during water depth measurement is ensured by the reinforcement of the fixed structure, and the accuracy of the surveying data is guaranteed. The auxiliary sleeve 4, which is fixed on the extension rod 2 or the outside of the surveying instrument pole, provides protection against detachment of the surveying probe connecting wire, and avoids excessive shaking of the wire during wire laying, which would affect its use.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
