Description

Technical Field

[0001] This utility model relates to the field of GNSS technology, and in particular to a geodesic GNSS receiver. Background Technology

[0002] Geodetic GNSS receivers, as high-precision spatial positioning devices, are widely used in outdoor scenarios such as engineering surveying, geological monitoring, and emergency disaster relief. Their core usage requirements focus on three aspects: rapid deployment, stable operation, and convenient maintenance. Especially in temporary stations (such as emergency disaster relief and mobile mapping), it is necessary to balance "rapid on-site installation" and "equipment reliability in complex environments."

[0003] Traditional GNSS receivers are often connected to brackets using bolts or tripods, requiring tools (such as wrenches) for installation. Deploying a single set of equipment typically takes 5-10 minutes. If equipment malfunctions and needs to be replaced, the disassembly process is equally cumbersome, making it difficult to meet the needs of rapid response in emergency scenarios. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing topographic GNSS receivers are time-consuming to deploy and install, and cannot meet the needs of emergency scenarios. Therefore, this invention proposes a geodetic GNSS receiver.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A geodetic GNSS receiver includes a pole, and a quick-connect assembly is provided between the pole and the GNSS receiver body. The quick-connect assembly is used for assembling and disassembling the pole and the GNSS receiver body. The quick-connect assembly includes an extension post and a connector that are fixedly connected to the GNSS receiver body; The extension column is provided with an elastic clip, and the top of the connector is provided with a connecting groove, the inside of which is provided with a snap-fit ​​groove that engages with the elastic clip.

[0006] In some embodiments, a photovoltaic panel is integrally connected to the GNSS receiver body, and the photovoltaic panel is fixedly connected to the extension column.

[0007] In some embodiments, the extension column is provided with a grooved plate, and an insertion plate is fixedly connected to the photovoltaic plate. The grooved plate and the insertion plate are provided with through holes, and bolts are used to connect and fix the photovoltaic plate to the extension column through the through holes.

[0008] In some embodiments, the elastic clamp includes a connecting post at the bottom of the extension post, the connecting post having a movable groove and an opening, the movable groove having a spring and an elastic plate inside, and the elastic plate extending outward from the connecting post via a push rod and a locking rod.

[0009] In some embodiments, there are two openings, with the upper opening being higher than the upper surface of the connector, the push rod being located above the snap-fit ​​rod, and a gap between the extension post and the connector serving as the movement space for the push rod.

[0010] In some embodiments, a protective ring is provided between the connecting post and the connector to protect the connecting groove.

[0011] In some embodiments, the inner side of the protective ring is bonded and fixed to the connecting post with double-sided adhesive, and the outer side of the lower surface of the protective ring is bonded and fixed to the upper surface of the connector with double-sided adhesive.

[0012] In some embodiments, the movable groove is provided with a limiting groove inside, and the elastic plate is provided with a protrusion that corresponds to and cooperates with the limiting groove. The limiting groove and the protrusion are used for smooth lateral sliding of the elastic plate.

[0013] Compared with the prior art, the present invention provides a geodetic GNSS receiver with the following advantages.

[0014] 1. This utility model enables the quick and easy connection and disassembly of the GNSS receiver body and the pole by hand through the cooperation of the spring-driven snap-fit ​​rod and snap-fit ​​groove, without the need for tools. The installation and disassembly time of a single set of equipment is reduced from 5-10 minutes in the traditional way to less than 1 minute, which significantly improves the emergency response speed and field operation efficiency.

[0015] 2. This utility model, through the elastic base at the bottom of the connecting groove and the elastic pad in the snap-fit ​​groove forming a buffer structure, can effectively absorb external forces such as ground-transmitted vibration, reduce the impact of vibration on the internal components of the receiver, and extend the service life of the equipment.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A geodesic GNSS receiver includes a pole 1, a GNSS receiver body 2 detachably mounted on the top of the pole 1, a photovoltaic panel 3 integrally connected to the GNSS receiver body 2, and a quick-connect assembly 4 between the GNSS receiver body 2 and the pole 1.

[0027] As one embodiment of the quick-connect assembly 4, the quick-connect assembly 4 includes an extension post 5 and a connector 6. The extension post 5 is fixedly connected to the GNSS receiver body 2, and the photovoltaic panel 3 is fixedly connected to the extension post 5. The extension column 5 is provided with a spring clip, and the top of the connector 6 is provided with a connecting groove 601. A snap-fit ​​groove 602 is provided on one side of the inner side of the connecting groove 601 to engage with the spring clip. As one embodiment of the elastic clip, the elastic clip includes a connecting post 501 at the bottom of the extension post 5. The connecting post 501 has a movable groove 502 inside. The movable groove 502 has a spring 504 and an elastic plate 503 inside. An opening 505 is opened on one side of the movable groove 502. One end of the spring 504 is fixedly connected to the side of the movable groove 502 away from the opening 505, and the other end of the spring 504 is fixedly connected to the elastic plate 503.

[0028] There are two openings 505. On the side of the elastic plate 503 away from the spring 504, there is a push rod 506 and a snap-fit ​​rod 507. The push rod 506 and the snap-fit ​​rod 507 correspond to the two openings 505 respectively. The push rod 506 is located at the top of the snap-fit ​​rod 507. There is a gap between the extension post 5 and the connector 6. The upper opening 505 is higher than the upper surface of the connector 6.

[0029] The movable groove 502 has a limiting groove inside, and the elastic plate 503 has a protrusion that corresponds to and cooperates with the limiting groove. The limiting groove and the protrusion are used for the smooth lateral sliding of the elastic plate 503.

[0030] In this utility model, the GNSS receiver body 2 and the extension post 5 are pre-fixed by screws. As a connection method between the GNSS receiver body 2 and the extension post 5, threaded holes are provided on the bottom of the GNSS receiver body 2 and the edge of the extension post 5. The GNSS receiver body 2 and the extension post 5 are pre-fixed by screws passing through the threaded holes. In this configuration, the photovoltaic panel 3 and the extension column 5 are pre-fixed. As one way to connect the photovoltaic panel 3 and the extension column 5, a grooved plate is welded to the extension column 5, and an insertion plate is fixedly connected to the photovoltaic panel 3. Through holes are opened on the grooved plate and the insertion plate, and the photovoltaic panel 3 is connected to the extension column 5 by bolts through the through holes. With this detachable fixing method, when the photovoltaic panel 3 is damaged or fails, the insertion plate can be removed together with the photovoltaic panel 3 after the bolts are removed for quick replacement and repair.

[0031] Initially, the pole 1 and the GNSS receiver body 2 are separate components carried separately. During on-site installation, by pressing the push rod 506 inward, the spring 504 is compressed, and the push rod 506 and the locking rod 507 retract inward along the opening 505, so that the end of the locking rod 507 located outside the connecting post 501 is retracted into the opening 505. At this time, the connecting post 501 is inserted downward to the bottom of the corresponding connecting groove 601, and the locking rod 507 is aligned with the locking groove 602. When the push rod 506 is released, the elastic plate 503 pushes the locking rod 507 outward under the rebound force of the spring 504, and inserts it into the corresponding locking groove 602. In this way, the GNSS receiver body 2 is quickly connected and fixed to the pole 1, which satisfies the purpose of rapid on-site installation.

[0032] If the GNSS receiver body 2 is damaged or malfunctions during use, the push rod 506 is pressed inward to disengage the locking rod 507 from the locking slot 602, and the GNSS receiver body 2 is pulled upward to disengage the connecting post 501 from the connecting slot 601, thus enabling the GNSS receiver body 2 to be quickly removed from the pole 1 for maintenance or replacement.

[0033] As a further improvement to the above solution, an elastic base 603 is provided at the bottom of the connecting groove 601, and an elastic pad 604 is provided inside the snap-fit ​​groove 602. During use, when vibration occurs in the area, such as when the GNSS receiver body 2 is deployed in engineering construction or emergency rescue, the elastic base 603 and elastic pad 604 prevent the vibration force from being directly transmitted to the interior of the GNSS receiver body 2. This allows the GNSS receiver body 2 to withstand the vibration force as a whole, reducing the intensity of the vibration force on the internal components of the GNSS receiver body 2, thereby reducing the degree of damage to the internal components of the GNSS receiver body 2. This extends the service life of the GNSS receiver body 2.

[0034] When the connecting post 501 is inserted into the connecting groove 601 for docking, the bottom of the connecting post 501 exerts downward pressure on the elastic base 603. The upward rebound force of the elastic base 603 is used to improve the stability of the connecting post 501 in the connecting groove 601 under normal conditions.

[0035] According to usage requirements, a protective ring 7 is provided between the connecting post 501 and the connector 6. The protective ring 7 is used to protect the top of the connecting groove 601 and prevent impurities from entering. Before the connecting post 501 and the connecting groove 601 are installed together, the protective ring 7 is fitted onto the connecting post 501. Double-sided adhesive is applied to the inner side of the protective ring 7 for connection and fixation with the connecting post 501. At the same time, double-sided adhesive is applied to the outer side of the lower surface of the protective ring 7. After the connecting post 501 is inserted into the connecting groove 601 and the snap-fit ​​rod 507 is connected to the snap-fit ​​groove 602, the outer side of the lower surface of the protective ring 7 is fixedly connected to the upper surface of the connector 6 using double-sided adhesive. When disassembling the GNSS receiver body 2, first detach the double-sided adhesive on the outer side of the lower surface of the protective ring 7 from the upper surface of the connector 6.

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.
