[0016] The following is a further detailed description through specific implementation methods:

[0017] like Figures 1 to 3 As shown:

[0018] A GNSS receiver protection device includes a fixing module, the fixing module includes a mounting tube 1 and a mounting plate 2, the mounting plate 2 is fixedly mounted on the top of the mounting tube 1, the mounting plate 2 is used to mount a GNSS receiver 3, and the mounting tube 1 is used to support the mounting plate 2; the device also includes a control unit, a lifting module and a protection module, the control unit is installed in the support tube, and is used to control the operation of other electrical components, the lifting module is used to drive the protection module to move up and down, so that the protection module can wrap the GNSS receiver 3, and the protection module has the function of wrapping and sealing the GNSS host;

[0019] The protection module includes a driving mechanism and a protection mechanism. The driving mechanism is used to drive the protection mechanism to move, and the protection mechanism is used to wrap and seal the GNSS receiver 3. The protection mechanism includes a fixed plate 8, a fixed sleeve 9, a driving ring plate 12 and an elastic sleeve 14. The fixed plate 8 and the driving ring plate 12 are respectively arranged at the upper and lower ends of the fixed sleeve 9. A movable groove 13 is opened at the driving ring plate 12. The movable groove 13 is adapted to the GNSS receiver 3 so that the GNSS receiver 3 can pass through the movable groove 13. The fixed plate 8 and the fixed sleeve 9 are sleeved outside the mounting tube 1. An elastic sleeve 14 is installed between the driving ring plate 12 and the mounting plate 2, so that when the driving ring plate 12 rotates, it can drive the elastic sleeve 14 to rotate together, so that the elastic sleeve 14 rotates to tighten the seal. A drainage hole is provided at one end of the elastic sleeve 14 close to the mounting plate 2, and a drainage hole is also provided at the fixed plate 8, so that when it rains, water can be discharged from the device through the drainage hole when it flows into the device.

[0020] The driving mechanism includes a driving motor 6, a driving gear 7, a fixed tube 10 and an internal gear 19. The driving motor 6 is installed in the mounting tube 1. The driving gear 7 is installed on the output shaft of the driving motor 6. An opening 11 is opened at the mounting tube 1. The opening 11 can prevent the side wall of the mounting tube 1 from hindering the driving gear 7 from meshing with the internal gear 19 installed on the top of the fixed tube 10. The bottom end of the fixed tube 10 is fixedly connected to the fixed plate 8. The fixed tube 10 is sleeved on the mounting tube 1, so that the connection between the fixed plate 8, the fixed sleeve 9 and the mounting tube 1 is more stable, reducing the possibility of shaking of the fixed plate 8, the fixed sleeve 9 and the driving ring plate 12.

[0021] The lifting module includes an annular guide rail 16, a driving plate and a plurality of electric push rods 18. The annular guide rail 16 is installed on the inner side of the fixed sleeve 9. A lifting plate 17 is installed in the annular guide rail 16 and the two are slidably connected, so that the lifting plate 17 can rotate in the annular guide rail 16 to prevent the electric push rods 18 installed between the mounting plate 2 and the lifting plate 17 from interfering with the rotation of the fixed sleeve 9.

[0022] The control unit includes a built-in battery 4 and a control host 5. The built-in battery 4 and the control host 5 are both installed in the installation tube 1. The built-in battery 4 and the control host 5 are both selected from existing mature products, and the user can configure them as needed. The control host 5 is electrically connected to the built-in battery 4, the drive motor 6, and the electric push rod 18.

[0023] A photovoltaic panel 15 is installed on the outer wall of the fixed sleeve 9 . The photovoltaic panel 15 is electrically connected to the control host 5 . The photovoltaic panel 15 can charge the built-in battery 4 through the control circuit in the control host 5 .

[0024] The elastic sleeve 14 is made of rubber material, so that the elastic sleeve 14 has good elasticity and can be twisted for multiple turns.

[0025] The specific implementation process is as follows:

[0026] When using the GNSS receiver protection device, firstly install the GNSS receiver 3 on the mounting plate 2. When the GNSS receiver 3 is working, the lifting module drives the protection module to descend, so that the GNSS receiver 3 passes through the active groove 13 at the driving ring plate 12 and is exposed to the outside world.

[0027] When the GNSS receiver 3 is in a non-working state, the control host 5 of the control unit controls the lifting module to start, the telescopic ends of each electric push rod 18 retract, the electric push rod 18 drives the annular guide rail 16 to move through the lifting plate 17, and the annular guide rail 16 drives the protection module to move upward until the electric push rod 18 retracts into place, at which time the inner gear 19 rises and meshes with the drive gear 7, and the fixed sleeve 9 and the elastic sleeve 14 are wrapped around the outside of the GNSS receiver 3; then the control host 5 controls the drive motor 6 to start, the drive motor 6 drives the drive gear 7 to rotate, and the drive gear 7 and The internal gear 19 meshes and rotates, and the internal gear 19 drives the fixed plate 8, the fixed sleeve 9, and the driving ring plate 12 to rotate through the fixed tube 10. When the driving ring plate 12 rotates, it drives the elastic sleeve 14 to move together, so that the elastic sleeve 14 rotates more than one circle, which can make the elastic sleeve 14 twist and block its opening 11, so that the top of the GNSS receiver 3 is blocked, so that a closed space is formed between the elastic sleeve 14 and the mounting plate 2, and the GNSS receiver 3 on the mounting plate 2 is closed and protected. At the same time, the fixed sleeve 9 can also protect the side of the GNSS receiver 3.

[0028] The photovoltaic panel 15 installed on the side of the fixing sleeve 9 can charge the built-in battery 4, and the built-in battery 4 can power the electronic components and the GNSS receiver 3 of the device.

[0029] The GNSS receiver protection device can drive the protection module to rise and fall at the mounting tube 1 and the mounting plate 2 through the lifting module, so that the protection module can wrap the GNSS receiver 3 installed on the mounting plate 2; when the protection module is started, the GNSS receiver 3 can be sealed and isolated from the outside world, thereby effectively protecting the GNSS receiver 3 and effectively extending the service life of the GNSS receiver 3; when the GNSS receiver 3 needs to work, the GNSS receiver 3 is released to prevent the device from affecting the signal reception of the GNSS receiver 3, thereby ensuring the normal operation of the GNSS receiver 3.
