[0024] See also Figure 1-4 is a schematic diagram of the structure of the present invention. An embodiment of the present invention provides a full-sky ribbon dome, comprising a base 1, an inner skylight 3, a middle skylight 5 and an outer skylight 6. A swivel seat 2 is respectively installed on both sides of the upper side of the base 1, both sides of the inner skylight 3 are rotatably installed on the swivel seat 2, both sides of the middle skylight 5 are rotatably installed on the swivel seat 2, and both sides of the outer skylight 6 are rotatably installed on the swivel seat 2;

[0025] A transmission structure 4 is installed on the base 1. There are two transmission structures 4. The transmission structures 4 are symmetrically distributed on both sides with the center line of the base 1 as the center.

[0026] The transmission structure 4 includes a driving structure 401, a reel 402, a webbing 403, a first top wheel 404, a first guide wheel 405, a second top wheel 406, a second guide wheel 407, a third top wheel 408, a third guide wheel 409 and a connecting seat 410;

[0027] The driving structure 401 is installed on the base 1, the reel 402 is installed on the driving structure 401, the webbing 403 is wound and connected to the reel 402, the first top wheel 404 is installed on the base 1, the first guide wheel 405 is installed in the inner skylight 3, the webbing 403 is transmitted on the first top wheel 404 and the first guide wheel 405, the second top wheel 406 is installed on the inner skylight 3, the second transmission wheel 407 is installed on the middle skylight 5, the webbing 403 is transmitted on the second top wheel 406 and the second guide wheel 407, the third top wheel 408 is installed on the middle skylight 5, the third guide wheel 409 is installed on the outer skylight 6, a connecting seat 410 is installed in the outer skylight 6, the webbing 403 is transmitted on the third top wheel 408 and the third guide wheel 409, and the webbing 403 is connected to the connecting seat 410.

[0028] It should be noted that, in the present embodiment, the base 1 is composed of a mesh steel structure, including an annular base and two triangular bearing supports symmetrically distributed on the outside of the base; a set of left-right split skylights and an opening and closing drive device are installed on the base, and the opening and closing rotation axis of the dome cover is arranged on the bearing support. The dome opening and closing cover is composed of a 6-petal rotatable skylight blade structure, which is divided into 3 petals on each side for symmetrical opening and closing (inner skylight 3, middle skylight 5 and outer skylight 6), and the opening and closing rotation center is the rotation axis on the bearing seat; each petal has mechanical limit and electronic limit protection devices at each extreme position, and the rotation axis used for the opening and closing of the skylight blades adopts a combined structure of a radial spherical roller bearing and a thrust ball bearing, which reasonably constrains the axial and radial loads generated when the opening and closing petals rotate, thereby ensuring the flexible opening and closing rotation performance of the dome cover, and the dome opening and closing adopts a mechanical drive mode. The driving device (transmission structure 4) is divided into two groups, left and right, and is installed on the fixed support structure of the base 1. The driving device (driving structure 401: motor, reducer, etc.) drives the webbing 403 wrapped around the reel 402 on the shaft to move, so as to realize the automatic opening and closing of the dome. The motor reducer fixed on the dome base 1 drives the reel 402 to rotate, and the reel 402 is fixed together with the webbing 403 of the inner skylight 3, driving the winding and unwinding of the webbing 403 of the inner skylight 3. The inner skylight 3, the middle skylight 5 and the outer skylight 6 are connected together by the fixed-length webbing 403. When working, the three skylights are opened and closed at the same time. The webbing 403 is made of ultra-high molecular weight polyethylene fiber with a specification of 100*4mm. It is a high-performance fiber that is impact-resistant, wear-resistant, has excellent self-lubricating properties and excellent low-temperature performance. The driving structure 401 is manually controlled by a button on an external control box.

[0029] Specifically, when in use, the button on the external control box is manually controlled to open the drive structure 401 (control the forward and reverse rotation of the motor), so that the webbing 403 wrapped around the reel 402 on the shaft moves, and the transmission of the webbing 403 between the top wheel and the guide wheel brings power to the connecting seat 410 to open and close the dome.

[0030] The inner skylight 3 is filled with heat-insulating cotton 9, the middle skylight 5 is filled with heat-insulating cotton 9, and the outer skylight 6 is filled with heat-insulating cotton 9;

[0031] A water baffle 10 is installed at the end of the outer skylight 6, a cavity 11 is opened in the water baffle 10, and an elastic member 12 is installed in the cavity 11;

[0032] A sealing gasket 7 is installed at the connection point between the inner skylight 3 and the middle skylight 5, and a sealing gasket 7 is installed at the connection point between the middle skylight 5 and the outer skylight 6;

[0033] A hand-cranked wheel 8 is installed at the tail of the driving structure 401 .

[0034] It should be noted that, in this embodiment, the inner and outer panels of the dome (the inner skylight 3, the middle skylight 5 and the outer skylight 6) are filled with thermal insulation cotton or polyurethane foam with a thickness of 2 cm to 3 cm to ensure the thermal insulation performance of the dome cover from the outside when it is closed. Figure 3 As shown, the filled dome has noise reduction, moisture resistance and flame retardant functions;

[0035] The water baffle 10 is made of fluororubber material, and when the outer skylights 6 on both sides are opened, the water baffle 10 contacts, and the elastic member 12 is made of elastic plastic material, and the length and shape are determined according to the shape of the water baffle 10 around the outer skylight 6;

[0036] The sealing gasket 7 is made of fluororubber, and is installed on the inner skylight 3, and is in close contact with the connection point of one end of the middle skylight 5, and its shape and size are determined according to the shape of the inner skylight 3, and another sealing gasket 7 is installed on the other end of the middle skylight 5, and is in close contact with the connection point of the outer skylight 6, and its shape and size are determined according to the shape of the middle skylight 5;

[0037] In addition to the normal mechanical belt drive mode, this design leaves a handle interface at the tail shaft of the drive motor to provide manual opening and closing of the dome skylight in the event of a power outage or a failure of the dome's electromechanical equipment. For the convenience of manual operation, the dome hand crank is designed in a hexagonal head shape to facilitate the operation of the electric crank.

[0038] Specifically, when in use, when the dome is opened, the relatively moving water baffles 10 come into contact to achieve top sealing, and during the transmission of the dome, the sealing gasket 7 seals the gap between the contacting skylights, so that the dome has the ability to prevent rain, snow, wind and dust, and has a good sealing design to prevent the entry of rain, dust, snow, etc., and the thermal insulation cotton or polyurethane foam filled between the inner and outer panels of the dome ensures the thermal insulation performance of the dome cover from the outside when closed. The filled dome has the functions of reducing noise, moisture-proof and flame retardant. When the power is off, the dome can also be opened or closed by the manual hand-cranked wheel 8.

[0039] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0040] The working process and working principle of the present invention are as follows: when in use, the button on the external control box is manually controlled to open the driving structure 401 (control the forward and reverse rotation of the motor), so that the webbing 403 wrapped around the reel 402 on the shaft moves, and the transmission of the webbing 403 between the top wheel and the guide wheel brings power to the connecting seat 410 to open and close the dome. When the dome is opened, the relatively moving water baffle 10 contacts to achieve top sealing. During the transmission of the dome, the sealing gasket 7 seals the gap between the contacting skylights, so that the dome has the ability to prevent rain, snow, wind and dust. It has a good sealing design to prevent the entry of rain, dust, snow, etc., and the thermal insulation cotton or polyurethane foam filled between the inner and outer panels of the dome ensures the thermal insulation performance of the dome cover from the outside when it is closed. The filled dome has the functions of reducing noise, moisture-proof and flame retardant. When the power is off, the dome can also be opened or closed by the manual hand-cranked wheel 8.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
