Description

Technical Field

[0001] The present invention relates to the technical field of GNSS receivers, and in particular to a geodetic GNSS receiver device. Background Art

[0002] A Global Navigation Satellite System receiver (GNSS receiver) is a device used to acquire signals from the Global Positioning Satellite System (GNSS) and determine the position of the receiver. The GNSS receiver can simultaneously receive signals from different GNSS satellite systems (such as GPS, GLONASS, Galileo, Beidou, etc.) to improve positioning accuracy and coverage. The working principle of the GNSS receiver is to receive signals from satellites and determine the position of the receiver by calculating the propagation time and distance of the signals. The receiver needs to receive signals from at least three satellites to perform two-dimensional positioning (longitude and latitude), and receiving signals from four or more satellites can perform three-dimensional positioning (longitude, latitude, and altitude). In practical applications, GNSS receivers are widely used in aviation, navigation, surveying and mapping, agriculture, transportation and other fields. In the fields of aviation and navigation, GNSS receivers are used for flight navigation, ship positioning, etc. to improve navigation accuracy and safety. In the fields of surveying and mapping and geographic information systems, GNSS receivers can provide high-precision position information for map making, spatial data collection and other work.

[0003] A geodetic GNSS receiver is a high-precision positioning device used for sub-centimeter-level high-precision positioning, geodynamic research, major project surveying and mapping and control, meteorological and space environment research. Some existing geodetic GNSS receivers are equipped with cameras for imaging monitoring. However, in actual use, the geodetic GNSS receivers are mainly installed outdoors. Due to being in the outdoor environment for a long time, the protective glass of the camera is easily attached with dust or blocked by foreign objects, resulting in poor imaging accuracy of the camera and affecting the use effect of the GNSS receiver. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings that some existing geodetic GNSS receivers are equipped with cameras for imaging monitoring. However, in actual use, the geodetic GNSS receivers are mainly installed outdoors. Due to being in the outdoor environment for a long time, the protective glass of the camera is easily attached with dust or blocked by foreign objects, resulting in poor imaging accuracy of the camera and affecting the use effect of the GNSS receiver, and to provide a geodetic GNSS receiver device.

[0005] The purpose of the present invention is achieved through the following technical solutions: A geodetic GNSS receiver device, on which an upper cover and an outer housing are installed on a base, a cavity is provided between the base and the upper cover, multiple groups of cameras are installed in the cavity, and a protective glass corresponding to the cameras is installed on the upper cover;

[0006] The outer housing is arranged on the outside of the upper cover. Multiple imaging holes corresponding to multiple groups of protective glasses are provided on the outer housing. A gap is provided between the upper cover and the outer housing. Multiple cleaning pads corresponding to the protective glasses are installed on the outer housing;

[0007] An installation groove and a sliding groove are provided on the base. The upper cover and the outer housing are respectively installed on the installation groove and the sliding groove. The outer housing is slidably connected to the sliding groove. An electric rotary slide is installed in the inner cavity. A sliding cavity is provided on the base. The moving end of the electric rotary slide passes through the sliding cavity and is connected to the outer housing;

[0008] A drainage channel is provided on the outside of the base. A drainage hole corresponding to the drainage channel is provided on the outer housing. The drainage channel is communicated with the gap between the upper cover and the outer housing through the drainage hole. By setting the electric rotary slide to drive the outer housing to rotate, multiple cleaning pads on the inner side of the outer housing clean the protective glass, effectively cleaning the dust and foreign objects attached to the protective glass. At the same time, multiple cleaning pads can sequentially clean the protective glass during the rotation of the outer housing, increasing the cleaning times to improve the cleaning effect. At the same time, the gap between the upper cover and the outer housing can make the cleaning pads located in the gap, preventing the cleaning pads from being in the external environment for a long time, thereby extending the service life of the cleaning pads. In rainy weather, rainwater can enter the gap to wash the cleaning pads, further ensuring the cleaning effect of the cleaning pads on the protective glass;

[0009] The cooperation of the drainage hole and the drainage channel ensures the drainage efficiency of the gap between the upper cover and the outer housing, preventing water from accumulating in the gap for a long time and damaging the service life of the equipment.

[0010] A further technical solution is that a GNSS module and a control module are installed in the inner cavity. The control module is respectively connected to the camera and the GNSS module. A shielding plate is provided between the GNSS module and the control module. By setting the shielding plate, the electromagnetic signals of other devices can be effectively shielded, preventing the GNSS module from being interfered by the electromagnetic signals of other devices, enabling the GNSS module to stably receive satellite signals, and improving the positioning accuracy and reliability.

[0011] A further technical solution is that a communication module connected to the control module is installed at the bottom of the base. The control module transmits data to an external control center through the communication module.

[0012] A further technical solution is that a waterproof pad is installed between the outside of the upper cover and the installation groove. By setting the waterproof pad between the outside of the upper cover and the installation groove, the sealing performance of the connection between the upper cover and the installation groove can be improved, preventing the water in the gap between the upper cover and the outer housing from flowing into the inner cavity, ensuring the sealing performance of the equipment, and improving the service life of the equipment.

[0013] A further technical solution is that a water channel is provided between multiple groups of cleaning pads. By setting up the water channel, rainwater can flow better between multiple groups of cleaning pads during rainy weather, thereby washing away the dust adhered to the cleaning pads when cleaning the protective glass, and improving the cleaning effect of the rainwater on the cleaning pads.

[0014] A further technical solution is that a sleeve is installed at the bottom of the base. A telescopic rod is installed at the bottom of the sleeve. An installation block is installed at the bottom of the rod. Multiple groups of equally spaced slots are provided on the rod. A threaded rod adapted to the slots is installed on the sleeve. One end of the threaded rod close to the sleeve can extend into the sleeve and be engaged with the slots. By setting the threaded rod on the sleeve to be inserted into different slots on the rod, the length of the rod on the sleeve can be adjusted, so that the device can be adapted to different installation terrains and improve the applicability of the device.

[0015] A further technical solution is that a solar panel is installed on the sleeve, and a storage battery is installed at the bottom of the base. The solar panel is connected to the storage battery through a charging controller. The output end of the storage battery is respectively connected to the camera, the GNSS module, the control module, the electric rotary slide and the communication module. By setting the solar panel, the storage battery and the charging controller to cooperate, the outdoor solar energy can be used for power supply, achieving energy conservation and emission reduction, avoiding laying out power supply lines, and effectively saving costs.

[0016] A further technical solution is that waterproof covers are installed on the bottom surfaces of the communication module and the storage battery. By setting the waterproof covers, the waterproof performance of the bottom surfaces of the communication module and the storage battery can be improved, and the communication module and the storage battery can be effectively protected.

[0017] The present invention has the following advantages: The present invention drives the outer casing to rotate by setting an electric rotary slide, so that multiple groups of cleaning pads inside the outer casing clean the protective glass, effectively cleaning the dust and foreign objects attached to the protective glass. At the same time, multiple groups of cleaning pads can clean the protective glass in turn during the rotation of the outer casing, increasing the cleaning times to improve the cleaning effect. At the same time, the gap between the upper cover and the outer casing enables the cleaning pads to be located in the gap, preventing the cleaning pads from being in the external environment for a long time, thereby extending the service life of the cleaning pads. During rainy weather, rainwater can enter the gap to wash the cleaning pads, further ensuring the cleaning effect of the cleaning pads on the protective glass. BRIEF DESCRIPTION OF THE DRAWINGS
