Description

Technical Field

[0001] This utility model relates to the field of protection-related technology, specifically to protective devices. Background Technology

[0002] GNSS, or Global Navigation Satellite System, uses observations such as pseudorange, ephemeris, and satellite launch time from a set of satellites for positioning. It also requires knowledge of the user's clock bias. A GNSS is a space-based radio navigation and positioning system that provides users with all-weather 3D coordinates, velocity, and time information from any location on the Earth's surface or in near-Earth space. It is widely used in surveying, engineering, construction, and Geographic Information Systems (GIS).

[0003] Currently, existing GNSS receivers contain numerous precision components, and the existing housings are designed to protect them from impacts and damage. If the housing is damaged due to external impact or pressure, the entire receiver needs to be replaced, which increases maintenance costs and complicates operations.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a protective device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a protective device, which is installed on the outside of the GNSS receiver body, including: a connecting column is provided on the top of the GNSS receiver body, and a protective cover unit for protecting against external impact is provided on the connecting column, the protective cover unit being composed of several adjacent spliced ​​protective sections;

[0007] A fixing component is correspondingly disposed on the protective section, used to abut the protective section against the top surface of the GNSS receiver body;

[0008] The connecting component includes two arc grooves disposed on the protective section and passing through it vertically, and an arc rod disposed in one of the arc grooves and spliced ​​with the adjacent arc groove.

[0009] Furthermore, the fixing component includes an abutment plate disposed inside the protective section, a movable guide rod disposed at the outer end of the abutment plate and slidably connected to the vertical surface of the inner cavity of the protective section, and a threaded rod that rotates through the protective section.

[0010] The bottom end of the threaded rod abuts against the upper end face of the abutment plate.

[0011] Furthermore, a plurality of evenly distributed damping shock absorbers are provided between the abutment plate and the protective section.

[0012] Furthermore, the connecting assembly also includes a compression spring disposed on the arc rod and close to the external opening of the arc groove.

[0013] Furthermore, the remaining external opening of the arc groove on the protective section is provided with a circular hole groove plate;

[0014] The central opening of the circular slot plate is inserted into the corresponding arc rod.

[0015] Furthermore, a transparent area is provided on the upper surface of the protective section.

[0016] Compared with the prior art, the present invention has the following advantages: The present invention, through the setting of the fixing component, can stably fix a single protection segment to the outside of the GNSS receiver body, thereby strengthening the protective capability of the GNSS receiver body shell. With the cooperation of the connecting component, it can quickly splice two adjacent protection segments while fixing a single protection segment to the outside of the GNSS receiver body, thereby improving the protective capability. It can also conveniently install, remove and replace a single protection segment, making the operation simpler and faster when replacing the protection segment and reducing maintenance costs.

Detailed Implementation

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0025] like Figure 1-4 As shown, the protective device of this utility model is applied to a GNSS receiver and is installed on the outside of the GNSS receiver body 100. It includes: a connecting post 1 is provided on the top of the GNSS receiver body 100, and a protective cover unit for protecting against external impact is provided on the connecting post 1. The protective cover unit is composed of several adjacent spliced ​​protective sections 2.

[0026] The fixing component 3 is correspondingly disposed on the protective section 2 and is used to abut the protective section 2 against the top surface of the GNSS receiver body 100;

[0027] The connecting component 4 includes two arc grooves 41 disposed on the protective section 2 and passing through it vertically, and an arc rod 42 disposed in one of the arc grooves 41 and spliced ​​with the adjacent arc groove 41.

[0028] In specific implementation, a connecting post 1 is fixed to the top of the GNSS receiver body 100 with screws, and a protective cover unit is installed on the connecting post 1. The protective cover unit is composed of four protective sections 2 that are cut into four equal parts and spliced ​​together. The four protective sections 2 are spliced ​​together into a whole and covered the outside of the GNSS receiver body 100. This can provide an outer layer of protection on the basis of the GNSS receiver body 100, thereby achieving the protection of the GNSS receiver body 100.

[0029] During the operation of the GNSS receiver body 100 or during the inspection and maintenance phase, the GNSS receiver body 100 can be disassembled and assembled via the fixing component 3 for inspection and maintenance.

[0030] Furthermore, through the cooperation of the fixing component 3 and the connecting component 4, not only can the protective section 2 outside the GNSS receiver body 100 be effectively fixed during the installation process, but also two adjacent protective sections 2 can be spliced ​​synchronously along the circumference of the GNSS receiver body 100, thus achieving the integrity of the four protective sections 2.

[0031] It should be noted that two arc grooves 41 are machined along the arc direction of the protective section 2 at the top and bottom of the vertical part of the protective section 2 by turning. Two arc rods 42 are symmetrically inserted into one of the arc grooves 41. The ends of the two arc rods 42 that are close to each other and the vertical surfaces on both sides of the movable guide rod 32 are machined with matching wedge surfaces. When the movable guide rod 32 descends, it will drive the symmetrically distributed arc rods 42 on both sides to move apart, realizing the splicing between adjacent protective sections 2.

[0032] In one embodiment, the fixing component 3 includes an abutment plate 31 disposed inside the protective section 2, a movable guide rod 32 disposed at the outer end of the abutment plate 31 and slidably connected to the vertical surface of the inner cavity of the protective section 2, and a threaded rod 33 rotatably passing through the protective section 2.

[0033] The bottom end of the threaded rod 33 abuts against the upper end face of the abutment plate 31. This design, with the abutment plate 31 installed at intervals in the lower section of the horizontal portion inside the protective section 2, and the movable guide rod 32 welded to the outer end of the abutment plate 31, allows the threaded rod 33 to descend when rotated. This is because the external thread on the outer wall of the threaded rod 33 rotates and connects with the internal thread of the opening on the protective section 2, until the threaded rod 33 contacts the upper surface of the abutment plate 31. The abutment plate 31 continues to be pushed downwards, and under the constraint of the movable guide rod 32 and the inner cavity surface of the protective section 2, it moves downwards, fixing the bottom surface of the abutment plate 31 to the top surface of the GNSS receiver body 100, thus achieving the fixation of the protective section 2 on the GNSS receiver body 100.

[0034] In one embodiment, a plurality of evenly distributed damping shock absorbers 5 are provided between the abutment plate 31 and the protective section 2. This design, with the multiple damping shock absorbers 5 screwed together between the abutment plate 31 and the protective section 2, ensures that vibrations generated by external impacts on the top of the protective section 2 are absorbed and offset by the damping shock absorbers 5, thus improving the overall vibration damping and protection capability.

[0035] In one embodiment, the connecting assembly 4 further includes a compression spring 43 disposed on the arc rod 42 and close to the external opening of the arc groove 41. This design allows the compression spring 43, welded to the end opening of the arc groove 41 with the arc rod 42, to be sleeved on the arc rod 42 and welded to its circumferential surface. When the arc rod 42 is subjected to circumferential compressive force, it will migrate laterally, causing the outer end of the arc rod 42 to insert into the arc groove 41 opened on the adjacent protective section 2. When there is no circumferential compressive force, the outer end of the arc rod 42 will detach from the end opening of the adjacent arc groove 41 due to the elastic recovery of the compression spring 43.

[0036] In one embodiment, the remaining external opening of the arc groove 41 on the protective section 2 is provided with a circular hole groove plate 6;

[0037] The central opening of the circular slot plate 6 is inserted into the arc rod 42. This design allows for a connection by welding a section of the circular slot plate 6 to the opening of the arc groove 41 (which does not have the arc rod 42), enabling it to be inserted into the outer end of the arc rod 42, thus ensuring the stability of the connection.

[0038] In one embodiment, a transparent area 21 is provided on the upper surface of the protective section 2. This design, by providing a transparent area 21 made of transparent acrylic sheet on the protective section 2, facilitates observation by personnel.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
