The main problems of sheep houses are ventilation and lighting. If the ventilation is poor, the environment will be hot and humid, and the air will be polluted. Especially for large-span sheep houses in large-scale farms, ventilation problems have always been a difficult problem to solve, and direct lighting in large-span sheep houses is not easy to achieve. In addition, the overall structure of the sheep house also needs to be reasonably designed based on the entire growth cycle of sheep breeding to meet the needs of sheep at different growth stages.

[0028] The present invention is further described below with reference to the embodiments.

[0029] like Figure 1-Figure 7A multi-span photovoltaic sheep shed is shown, which includes a sheep shed body, which includes a frame 1 and a photovoltaic panel 2 and a roller shutter arranged on the frame 1; the frame 1 includes a plurality of rows of portal frames 101, and each row of portal frames 101 is formed by a plurality of separate portal frames 101 connected to each other; a herringbone top frame 102 is provided on the top of the portal frame 101, and the slopes on both sides of the top frame 102 have different lengths, the side with the long slope faces the sun and is laid with the photovoltaic panel 2, and the side with the short slope is provided with an electric roller shutter 301; roller shutter modules 302 are respectively provided on the left and right sides of the overall frame 1, and composite board walls 4 are respectively provided on the front and rear parts of the overall frame 1.

[0030] The top frame 102 includes two inclined rods 1021 corresponding to each other, and the two inclined rods 1021 are arranged in the form of sliding supports. The two inclined rods 1021 corresponding to the top frame 102 are of different lengths and correspond to two slopes of different lengths respectively. The top of the shorter inclined rod 1021 is slidably supported to the bottom of the longer inclined rod 1021; the gantry 101 is provided with a support rod 1022 for supporting and driving the two inclined rods 1021, the support rod 1022 is horizontally arranged and the two ends are respectively slidably supported to the bottom of the two inclined rods 1021, and the support points of the support rod 1022 and the inclined rod 1021 are sliding support points; the horizontal lifting of the support rod 1022 can drive the inclination angle of the two oblique sides 1021 to change. When the inclination angle of the two oblique sides 1021 changes, the position of the sliding support point will also change accordingly. Therefore, it is necessary to overcome the change of the support point position to set the corresponding lifting drive structure during design. Here we design a horizontal support rod 1022 to ensure the normal lifting drive. During the lifting process, the support rod 1022 will be displaced in the horizontal direction, so it is necessary to design a corresponding sliding mechanism so that the support rod 1022 can slide in the horizontal direction while lifting.

[0031] The gantry frame 101 and the top frame 102 adopt an assembled structure. The gantry frame 101 includes a column 1011 and a cross bar 1012. The column 1011 is a square structure, and connecting ears 1013 are respectively arranged around the top. The columns 1011 are connected by the cross bar 1012, and the two ends of the cross bar 1012 are respectively connected to the corresponding connecting ears 1013 on the adjacent columns 1011; the longitudinally adjacent gantry frames 101 are connected by a longitudinal rod 1014, and the two ends of the longitudinal rod 1014 are respectively connected to the corresponding connecting ears 1013 on the gantry frame 101; a hinge seat 1015 is provided on the top of the column 1011, and the bottoms of the two corresponding oblique sides 1021 of the top frame 102 are respectively hinged to the hinge seat 1015 on the top of the corresponding column 1011.

[0032] The horizontal rod 1012, the longitudinal rod 1014, the diagonal rod 1021, and the support rod 1022 are all made of I-beams, and the column 1011 is made of square steel; the connecting ear 1013 is a two-half structure, and the connecting ear 1013 is inserted into both sides of the I-beam and connected by welding or bolting; each hinge point and sliding support point of the diagonal rod 1021 are realized by the connecting piece 103, and the bottom of the I-beam corresponding to the two diagonal rods 1021 is connected by the connecting piece 103 is hinged on the hinge seat 1015, and the sliding supports of the two oblique rods 1021 are supported and slid by the connecting piece 103. Both ends of the support rod 1022 are supported to the lower part of the oblique rod through the connecting piece 103; the connecting piece 103 includes a C-shaped slider 1031 and a tail plug 1032, and the C-shaped slider 1031 corresponds to the two sides of the I-beam and slides along the grooves on both sides thereof, and the tail of the C-shaped slider 1031 is provided with a tail plug inserted into the end of the I-beam.

[0033] The structure of I-beam and square steel is used in conjunction with the connector 103 to achieve the effect of prefabricated construction. It has strong flexibility in actual use. Since the height of the entire frame is consistent, the column 1011 can achieve a universal effect. The connecting ear 1013 of the column 1011 located on the outer side of the entire frame 1 can also be used for the subsequent installation of other equipment. In the actual construction process, only square steel, I-beam and connector 103 are needed for construction. The I-beam is cut according to the design and requirements and used for the connection and installation of various parts. The cut I-beam only needs to be equipped with a connector 103 at the end to meet the overall practical needs, and is used for the connection between rods and between rods and columns.

[0034] In this embodiment, the gantry 101 includes three columns 1011, which are arranged in sequence horizontally, and the three columns 1011 are connected by two cross bars 1012; the middle column 1011 is eccentrically designed, corresponding to the area where the sliding support points of the two oblique bars 1021 are located, and a telescopic rod 1016 is provided on the middle column 1011, and a C-shaped clamping portion 1017 with an opening upward is provided on the top of the telescopic rod 1016, and the clamping portion 1017 performs a sliding clamping on the I-beam structure of the support rod 1022, and when the telescopic rod 1016 rises, it drives the clamping portion 1017 and the support rod 1022 to rise, and the support rod 1022 synchronously moves horizontally during the rising process and slides in the clamping portion 1017. In this structure, the middle column 1011 is a relatively fixed structure, and when the angles of the two diagonal rods 1021 change, the positions of their sliding support points also change. The changes in the vertical direction are driven and offset by the telescopic rod 1016, and the horizontal sliding requires the support rod 1022 to slide in the clamping part 1017 to offset.

[0035] A bracket 1023 for mounting the photovoltaic panel 2 is also provided on the upper part of the top frame 102. The bracket 1023 is a square frame structure. A fixing piece 1024 corresponding to the longer diagonal rod 1021 on the top frame 102 is provided at the bottom of the bracket 1023. The fixing piece 1024 fixes the bracket 1023 on the upper part of the bevel. The width of the bracket 1023 is an integer multiple of the distance between the longitudinally adjacent top frames 102, and the multiple is greater than or equal to 2. The edge of the bracket 1023 corresponds to the center between the adjacent top frames 102. The width and installation position of the electric roller shutter 301 correspond one-to-one with the bracket 1023. The bracket-type structure enables the photovoltaic panel 2 to be better installed on the top frame 102, and the edge of the bracket 1023 is not supported on the inclined rod 1022, but corresponds to between adjacent inclined rods 1022. The design structure of the electric roller shutter 301 is consistent with it. The main purpose is to achieve local adjustment of the photovoltaic panel 2 and the electric roller shutter 301. If the photovoltaic panel 2 and the electric roller shutter 301 are supported on the inclined rod 1021, then when partially opened, it will inevitably drive the adjacent photovoltaic panel 2 and electric roller shutter 301, and the effect of partial opening cannot be achieved.

[0036] In the overall frame 1, a separate column 1011 and a crossbar 1012 are provided on the gantry frame 101 corresponding to the outermost side of the photovoltaic panel 2. A horizontal photovoltaic panel 2 is laid on the top of the column 1011 and the crossbar 1012. The photovoltaic panel 2 and the corresponding column 1011 and crossbar 1012 form a sunshade and rainproof canopy 8, and the roller shutter module 302 on this side is installed on the outer column 1011.

[0037] The corresponding columns 1011 on both sides of the frame 1 are provided with longitudinally uniformly distributed longitudinal rods 1013, and the rolling shutter module 302 is provided in the area formed between adjacent longitudinal rods 1013 and adjacent columns 1011. In this embodiment, three longitudinal rods 1013, namely upper, middle and lower, are provided on the outer columns 1011. The longitudinal rods 1013 divide the area between the columns 1011 into two spaces, and the rolling shutter modules 302 are respectively provided in the two spaces.

[0038] The rolling shutter module 302 includes two corresponding rolling shutters 3021 in the upper and lower parts and a rolling shutter frame 3022 arranged between the columns 1011, the rolling shutters 3021 are respectively arranged on the outer side of the upper longitudinal rod 1013 and the inner side of the lower longitudinal rod 1013, the center of the rolling shutter frame 3022 is hinged on the column 1011, the rolling shutter frame 3022 is a square ring structure, and is rotated manually or electrically; the rolling shutter 3021 is an automatically retractable rolling shutter, including a rolled curtain 3023 and a torsion spring 3024 arranged at the center of the curtain 3023, the free end of the upper curtain 3023 is connected to the top of the rolling shutter frame 3022, and the free end of the lower curtain 3023 is connected to the bottom of the rolling shutter frame 3022, and the rotation of the rolling shutter frame 3022 drives the curtain 3023 to be pulled out to the desired angle or completely cover the area of ​​the rolling shutter frame 3022. The rolling shutter module 302 includes two parts of curtains. The upper and lower curtains 3023 can be driven respectively by the rotation of the rolling shutter frame 3022. When complete ventilation is required, the curtains 3023 can be kept at their respective tops and bottoms. When closing is required, the rolling shutter frame 3022 is rotated so that its top rotates outward and its bottom rotates inward. During rotation, the top and bottom of the rolling shutter frame 3022 pull out the outer and inner curtains respectively. When the rolling shutter frame rotates 180 degrees, the free end of the top curtain 3023 is driven to the outer bottom of the column 1011, and the free end of the inner curtain 3023 is driven to the inner top of the column 1011 to achieve closure of the area. When the rotation angle of the rolling shutter frame 3022 is less than 180 degrees, the curtain forms an inclined flow channel structure inclined inwardly and upwardly, which can prevent ventilation from blowing directly onto the surface of the sheep in the house.

[0039] The laterally adjacent door frames 101 are connected by an I-shaped connecting rod 104, and the connecting rod 104 is respectively connected to the connecting ears 1013 on the column 101. The lower part of the connecting rod 104 is provided with a gutter 105, and the gutter 105 collects rainwater carried by the photovoltaic panels 2 and the electric roller shutter 301 on the adjacent top frame 102.

[0040] A longitudinal fence 5 is provided in the frame 1 corresponding to the sheep house body, a dung-leaked floor 501 is laid in the fence 5, a dung trough 502 and a dung collecting conveyor belt 503 are provided at the lower part of the dung-leaked floor 501, and a transverse dung trough 502 and a dung collecting conveyor belt 503 are also provided in the sheep house body, and the transverse dung trough 502 and the dung collecting conveyor belt 503 correspond to the ends of the longitudinal dung trough 502 and the dung collecting conveyor belt 503; two symmetrical groups of fences 5 are provided in each row of gantry frames 101, one group of fences 5 corresponds to the middle column 1011 and the column 1011 that is relatively closer, and the area between the other group of fences 5 and the middle column 1011 where no fence 5 is provided is a feeding channel 6; the area between the transversely adjacent gantry frames 101 is a group transfer channel 7.

[0041] The sheep house corresponding to this device has the following main advantages in actual use. First, the overall assembly of the sheep house. The assembled structure is extremely convenient for the installation of the sheep house. The overall assembly parts required are relatively simplified, which greatly reduces the construction cost of the sheep house. Secondly, the assembled structure facilitates the construction of large-span multi-span sheep houses.

[0042] The main design point lies in the design of the ventilation structure. Roller shutter structures for ventilation are set on the roof and sides of the house. The electric roller shutter 301 on the top can be opened and closed to ensure the ventilation effect on the top. The roller shutter module 302 on the side enables the sides of the sheep house to achieve opposite ventilation effect.

[0043] The sliding top frame 102 structure on the top of the sheep house allows the inclination angles of the photovoltaic panel 2 and the electric roller shutter 301 on the top to be adjusted, which can ensure a better sun-facing effect of the photovoltaic panel 2, and can also adjust the angle of the inclined rod 1021 corresponding to the electric roller shutter 301 according to the wind force to achieve regulation of the air intake and exhaust volumes. The larger the inclination angle, the more air volume will be injected into the house when natural wind passes through, accelerating the air flow in the house. At the same time, more air volume will be discharged when the air in the house flows in the opposite direction.

[0044] The key point of the structure of the rolling curtain module 302 is that the wind direction and wind volume are adjusted by driving the opening and closing of the curtain 3023 by rotating the rolling curtain frame 3022. When the curtain 3023 of the upper rolling curtain 3021 is not opened, the two sides of the sheep house are open to achieve the best ventilation effect. When the side of the sheep house needs to be closed, the rolling curtain frame 3022 is rotated so that the top of the rolling curtain frame 3022 drives the curtain 3023 to open. When the top of the rolling curtain frame 3022 is rotated to the bottom, the curtain 3021 covers the vertical The outer side of the column 1011, and at the same time, the bottom of the rolling curtain frame 3022 drives the inner curtain 3021 to cover the inner side of the column 1011 to achieve an overall closed effect; in addition, when the rolling curtain frame 3022 is partially opened, the curtain 3023 forms an inclined channel structure. If the wind speed is high during use, in order to avoid the wind blowing directly to the sheep's body surface and causing discomfort to the sheep, the inclined channel structure of the curtain 3023 can guide the wind and minimize the natural wind blowing directly to the sheep.

[0045] The electric roller shutter 301 and the roller shutter module 302 can also cooperate to realize ventilation in the house. When the wind blows from the shady side to the sunny side, the curtain 3023 is arranged in an inclined structure, and the air flow in the house is as follows: Figure 8 As shown, the air flows from the left side to the top of the house through the guidance of the curtain 3023, and the air on the top frame 102 enters the equipment through the electric roller curtain 301, and is gathered at the top of the house to flow toward the sunny side; when the air flows from the sunny side to the non-sun side, the flow mode is opposite to the above path, such as Fig. 9As shown, when the air flows through the sun-proof side of the top frame 102 , part of the air can be released by opening the electric roller blind 301 .
