[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the problem that the relative position between the optical collector 1 and the muzzle changes during the movement of the existing muzzle, which affects the accuracy and stability of the optical collector 1, the calibration can only be performed after corresponding adjustments, and there are technical problems with limitations, such as Figure 1 - Figure 5 As shown, the following preferred technical solutions are provided: A muzzle fixing device for a star aiming and collecting device comprises an optical collector 1 and a barrel 2. A fixing component 3 is fixedly installed on a side wall at one end of the barrel 2. The optical collector 1 is fixedly installed inside the fixing component 3. The optical collector 1 consists of an optical component and an imaging element, has a function of imaging stars day and night, and can receive a synchronous trigger signal from an operation terminal, and is mainly used for collecting star imaging. The shell is square, and a fixing sleeve 31 is inserted into the rear end and installed at the muzzle. By setting the fixing component 3, the position of the optical collector 1 can be adjusted while adjusting the muzzle position, and the star can be aimed at together with a true value theodolite, the star can be locked to read data, the data deviation can be calculated to obtain a zero position, calibration can be achieved, and work efficiency can be improved. The invention also has a simple structure, easy fixing operation, and reliable installation.

[0022] The side wall of the barrel 2 is fixedly installed with a calibration component 4. By setting the calibration component 4, after the optical collector 1 is installed, the rotating rod 42 is rotated, and the crank 43 is driven to rotate by the rotation of the rotating rod 42. Under the rotation cooperation of the two connecting rods 44, the two movable plates 45 are brought close to each other, and at the same time, the first calibration plates 413 on both sides are driven to approach synchronously through the connecting plate 412 until the second calibration plate 414 contacts the side wall of the fixed sleeve 31, and the fixed sleeve 31 is vertically calibrated. The first calibration plate 413 and the second calibration plate 414 are embedded with a sliding limit block 416 and a second spring 417, which can effectively calibrate the fixed sleeve 31. Elastic clamping, and when the two movable plates 45 approach each other, the wedge block 411 will be pushed to compress the first spring 410 and enter the groove body 49. When the second calibration plate 414 contacts the side wall of the fixed sleeve 31, the wedge block 411 will be popped out under the elastic action of the first spring 410, thereby limiting and fixing the slider 48 and the movable plate 45, so that the second calibration plate 414 can fix and clamp the fixed sleeve 31, avoiding the fixed sleeve 31 from angular deviation after long-term use, affecting the normal operation of the optical collector 1, and improving the accuracy and stability of the device by calibrating and fixing the fixed sleeve 31.

The piston plate 57 is reciprocated, and the pressure difference generated by the reciprocating motion of the piston plate 57 is utilized to inhale the outside air into the sealing box 51 along the air inlet pipe 52, and discharge it through the air blowing pipe 54.

The fixing sleeve 31 is divided into three sections, a square section, a cylindrical section and an intermediate disc section. The square section wraps the square rear section of the optical collector 1, and the cylindrical section is inserted into the muzzle of the barrel 2. The intermediate disc section is connected and aligned with the first clamp 32 and the second clamp 33. The end face of the disc section is provided with four circular holes, which are aligned with the threaded holes of the first clamp 32 and the second clamp 33 and are connected by bolts 34.

[0026] The first clamp 32 and the second clamp 33 are both in the shape of a semi-circular ring, with a circular hole machined at one end of the ring and a radial boss machined at the other end; the axial positioning U-shaped protrusion is connected to the axial U-shaped groove of the water jacket clamping nut of the barrel 2, and the circular ring surface is inserted into the groove of the water jacket clamping nut on the barrel 2; one end of the slotted circular hole is aligned and inserted into an elastic cylindrical pin 36 for connection, and the radial boss at the other end is aligned and clamped by a screw 35; two threaded holes are machined on the end surface of the circular ring, and bolts 34 can be tightened to fix the fixed sleeve 31; while adjusting the muzzle position, the position of the optical collector 1 can be adjusted, and the star can be aimed at together with the true value theodolite, the star can be locked to read data, the data deviation can be calculated to obtain the zero position, calibration can be achieved, and work efficiency can be improved; the structure is simple, the fixing operation is easy, and the installation is reliable.

[0027] In order to solve the technical problem that during the installation of the fixing sleeve 31 and long-term use, the fixing sleeve 31 will cause a certain angle deviation, which will affect the operation of the optical collector 1, such as Figure 6 - Fig.12 As shown, the following preferred technical solutions are provided: The calibration assembly 4 includes a fixed block 41, which is fixedly connected to the outer wall of the barrel 2. The top of the fixed block 41 is rotatably connected to a rotating rod 42, the side wall of the rotating rod 42 is fixedly connected to a crank 43, and the top of the crank 43 is rotatably connected to a connecting rod 44 along a diagonal line.

[0028] The bottom end of the fixed block 41 is fixedly connected to a bottom plate 46, and the top of the bottom plate 46 is symmetrically provided with slide grooves 47. Each slide groove 47 is slidably connected with a slider 48. The top of each slider 48 is fixedly connected to a moving plate 45, and the top of the moving plate 45 is rotatably connected to the adjacent connecting rod 44.

[0029] A slot body 49 is formed on the inner bottom wall of each slide slot 47 . A first spring 410 is fixedly connected to the inner bottom wall of the slot body 49 . A wedge block 411 is fixedly connected to the top of the first spring 410 . The wedge block 411 is slidably connected to the inside of the slot body 49 .

[0030] Each movable plate 45 has a side wall fixedly connected to a connecting plate 412, one end of the connecting plate 412 is fixedly connected to a first calibration plate 413, the side wall of the first calibration plate 413 is symmetrically fixedly connected to a limiting cylinder 415, each limiting cylinder 415 has an inner wall embedded with a slidingly connected limiting block 416, and a plurality of limiting blocks 416 are commonly fixedly connected to a second calibration plate 414, the side wall of the first calibration plate 413 is symmetrically fixedly connected to a plurality of second springs 417, each second spring 417 is located inside the limiting cylinder 415, and the second spring 417 is fixedly connected to the side wall of the adjacent limiting block 416.

[0031] In this solution: after the optical collector 1 is installed, the rotating rod 42 is rotated, and the crank 43 is driven to rotate by the rotation of the rotating rod 42. Under the rotation cooperation of the two connecting rods 44, the two movable plates 45 are brought close to each other, and the first calibration plates 413 on both sides are driven to approach synchronously through the connecting plate 412 until the second calibration plate 414 contacts the side wall of the fixed sleeve 31, and the fixed sleeve 31 is vertically calibrated. The first calibration plate 413 and the second calibration plate 414 are embedded with the sliding limit block 416 and the second spring 417, which can effectively elastically clamp the fixed sleeve 31, and the two calibration plates 413 and 414 are connected. When the moving plates 45 approach each other, the wedge block 411 will be pushed to compress the first spring 410 and enter the groove body 49. When the second calibration plate 414 contacts the side wall of the fixed sleeve 31, the wedge block 411 will be popped out under the elastic action of the first spring 410, thereby limiting and fixing the slider 48 and the moving plate 45, so that the second calibration plate 414 can fix and clamp the fixed sleeve 31, avoiding the angular deviation of the fixed sleeve 31 after long-term use, affecting the normal operation of the optical collector 1, and improving the accuracy and stability of the device by calibrating and fixing the fixed sleeve 31.

[0032] In order to solve the technical problem that after long-term use, the connection between the fixing sleeve 31 and the optical collector 1 will be affected by dust, and if the dust is not cleaned in time, it will affect the normal installation of the optical collector 1 and the fixing sleeve 31. Fig.13 - Fig.15 As shown, the following preferred technical solutions are provided: The auxiliary component 5 includes a plurality of sealing boxes 51, each of which is fixedly connected to the side wall of the first calibration plate 413, each of which is symmetrically fixedly connected to a mounting plate 511, and each of which is symmetrically fixedly connected to a positioning block 513.

[0033] The side wall of the mounting plate 511 is fixedly connected with an electromagnet 512 , the inner wall of each positioning block 513 is slidably connected with a slide rod 56 , one end of the slide rod 56 is fixedly connected with a piston plate 57 , and each piston plate 57 is sealingly and slidably connected to the inner wall of the adjacent sealing box 51 .

[0034] The other end of the slide rod 56 is fixedly connected to a push plate 58, and a permanent magnet 59 is fixedly connected to a side wall of one side of the push plate 58. The other side wall of the push plate 58 is symmetrically fixedly connected to a third spring 510.

[0036] In this solution, when dust exists between the connection between the fixed sleeve 31 and the optical collector 1, the electromagnet 512 is energized, so that the electromagnet 512 generates magnetic poles after being energized, and the magnitude of the energization is changed by an external sliding rheostat, so that the strength of the magnetic poles generated by the electromagnet 512 is constantly changing. In the initial state, the magnetic poles generated by the electromagnet 512 after being energized, and the magnetic repulsion generated by the adjacent ends of the electromagnet 512 and the permanent magnet 59 are used to make the slide bar 56 drive the piston plate 57 to move, and as the amount of energization decreases, the electromagnetic force of the electromagnet 512 is weakened, and under the elastic action of the third spring 510, the push plate 58 and the piston plate 57 are pushed to reset, thereby approaching the electromagnet 51. 2. As the electromagnet 512 is approached, the amount of current increases again, so that the magnetic force is strengthened again, and the permanent magnet 59 and the piston plate 57 continue to be pushed away, and the cycle repeats, so that the piston plate 57 reciprocates, and the pressure difference generated by the reciprocating motion of the piston plate 57 is used to suck the external air into the sealing box 51 along the air inlet pipe 52, and discharge it through the air blowing pipe 54. The blowing force generated by the simultaneous operation of multiple air blowing pipes 54 can clean the dust at the connection between the fixing sleeve 31 and the optical collector 1, and can also clean the dust near the inside, thereby improving the cleaning degree and timely cleaning the dust, avoiding the normal installation of the optical collector 1 and the fixing sleeve 31 being affected by the dust.
