Description

Technical Field

[0001] This utility model relates to the field of solar greenhouses, specifically to a semi-enclosed multi-span film greenhouse with good energy-saving performance. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through while maintaining (or heating) heat for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield. It is primarily used for cultivating or raising seedlings of warm-weather vegetables, flowers, and trees during cold seasons. There are many types of greenhouses, categorized by their roof frame materials, lighting materials, shape, and heating conditions. Broadly speaking, a shed is a type of greenhouse. Its purpose is also to maintain a certain temperature.

[0003] A search revealed that Chinese patent CN214178305U discloses a "ventilation structure for a film greenhouse roof window," comprising a greenhouse frame, a roof window slidably connected to the top of the frame, a transmission component engaged on one side of the roof window, and an active component engaged at the bottom of the transmission component. The active component is fixedly installed in the middle of the greenhouse frame. The roof window includes a window body, a connecting plate, rollers, a rack, and a limiting block. The advantages of this invention are: by setting rollers that overlap the top of the greenhouse frame, a servo motor is activated when ventilation is needed. The servo motor drives a fifth gear, which in turn drives the transmission component, causing the roof window to slide towards the top of the greenhouse frame, opening the roof window. To close the window, the motor is reversed, making opening and closing convenient and achieving ease of use. This structure does not require additional support rods or frames and can be directly installed on the existing frame of the film greenhouse, thus improving its applicability. However, it still has the following drawbacks:

[0004] (1) Existing open window structures often use the friction effect of rollers to drive the window panel to open. However, after long-term use, the rollers will wear out, causing the roller surface to become smooth and eventually lose friction, making it impossible to open the window panel normally and affecting the convenience of opening the window.

[0005] (2) The existing greenhouse has flat glass on the top. When the window is opened, it opens vertically upwards. After opening, it needs to be supported by a support structure. The support structure needs to be set up separately and there is a possibility of accidental contact causing the support structure to fall off, which causes the window to close automatically and affects the stability of the window opening.

[0006] Therefore, we have made improvements and proposed a semi-enclosed film multi-span greenhouse with good energy-saving performance. Utility Model Content

[0007] The purpose of this utility model is to address the problem that rollers wear out after prolonged use, causing the roller surface to become smooth and eventually lose friction, making it impossible for the window panel to open normally. When the window is opened, a support structure is required for auxiliary support. However, the support structure needs to be set up separately, and there is a risk of accidental activation and dislodging, which causes the window to close automatically when opened.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A semi-enclosed multi-span film greenhouse with good energy-saving performance is proposed to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] Includes a main frame, with a guy wire beam at the center of the main frame, an external sunshade longitudinal beam at the upper end of the guy wire beam, a light-transmitting component between the external sunshade longitudinal beams, and a tensioning component at the upper right side of the light-transmitting component;

[0012] The light-transmitting component includes a support rod arranged at the center of the outer sunshade longitudinal beam, a left top provided on the left side of the support rod, and a right top provided on the right side of the support rod;

[0013] The opening and closing assembly includes a rotating shaft located at the upper left and right sides, with a window panel rotatably connected to the lower end of the rotating shaft.

[0014] As a preferred technical solution of this utility model, the left top and right top are semi-circular arcs.

[0015] As a preferred technical solution of this utility model, the opening and closing assembly further includes an electric gear disposed on the upper surface of the right top left end, and a toothed plate that cooperates with the electric gear is disposed on the left side surface of the window plate.

[0016] As a preferred technical solution of this utility model, a sealing seat is provided on the upper right side surface at the lower right end of the electric gear, and a sealing strip that cooperates with the sealing seat is provided on the lower side wall of the window plate.

[0017] As a preferred technical solution of this utility model, the tooth patterns on the surface of the electric gear cooperate with the tooth patterns on the upper surface of the gear plate.

[0018] As a preferred technical solution of this utility model, the cross-sectional dimensions of the sealing strip are matched with the cross-sectional dimensions of the sealing seat.

[0019] As a preferred technical solution of this utility model, the length of the window panel is matched with the distance from the pivot to the upper right side surface.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. The semi-circular left and right tops allow sunlight to effectively enter the greenhouse from different directions, while the semi-circular glass tops on both sides allow the windows to open at an angle to facilitate air circulation, and at the same time provide a more airtight seal when the windows are closed.

[0023] 2. Through the set rotating shaft, window panel, electric gear, and toothed plate, when the window panel needs to be opened, the electric gear is controlled to rotate under the drive of the motor. The electric gear meshes with the toothed plate through the teeth set on the outer wall. The position of the electric gear is fixed, so that the toothed plate moves to the right relative to the electric gear. The toothed plate moves to the right and pushes the window panel. The window panel rotates to the right and opens under the connection of the upper rotating shaft, thus completing the diagonal opening of the window panel. When it is necessary to close, the electric gear is controlled to rotate in the opposite direction, so that it meshes with and drives the toothed plate to slide to the left, thus pulling the window panel to the left. Under the rotation of the rotating shaft, the window panel rotates to the left and closes, so that the sealing strip at the lower end is embedded in the sealing seat, achieving the sealing effect of the window panel opening.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1-3As shown, this embodiment proposes a novel film greenhouse window structure with good sealing performance, including a main frame 1, a tie beam 2 is provided at the center of the main frame 1, an external shading longitudinal beam 3 is provided at the upper end of the tie beam 2, a light-transmitting component is provided between the external shading longitudinal beams 3, and a tensioning component is provided at the upper right end of the light-transmitting component.

[0031] The light-transmitting component includes a support rod 402 set at the center of the outer sunshade longitudinal beam 3, a left top 401 set on the left side of the support rod 402, and a right top 403 set on the right side of the support rod 402.

[0032] The opening and closing assembly includes a rotating shaft 501 located at the upper right end of the left top 401, and a window panel 502 is rotatably connected to the lower end of the rotating shaft 501.

[0033] like Figure 2 As shown, the left top 401 and right top 403 are semi-circular arc-shaped so that sunlight can effectively enter the greenhouse from different directions. At the same time, the arc-shaped glass tops on both sides allow the window panels 502 to open obliquely so that air can circulate effectively, and the window panels 502 are more airtight when closed.

[0034] like Figure 2 As shown, the opening and closing assembly also includes an electric gear 503 disposed on the upper surface of the left end of the right top 403, and a toothed plate 504 disposed on the left side surface of the window panel 502 that cooperates with the electric gear 503. When the window panel 502 needs to be opened, the electric gear 503 is controlled to rotate under the drive of the motor. The electric gear 503 drives the toothed plate 504 through the meshing of the teeth disposed on the outer wall. The position of the electric gear 503 is fixed.

[0035] like Figure 2 As shown, a sealing seat 506 is provided on the upper surface of the right top 403 at the lower right end of the electric gear 503. A sealing strip 505 is provided on the lower side wall of the window plate 502, which cooperates with the sealing seat 506. When the window plate 502 is rotated to the left to close, the sealing strip 505 at the lower end is embedded in the sealing seat 506, thereby achieving a sealing effect on the opening of the window plate 502.

[0036] like Figure 3 As shown, the teeth on the surface of the electric gear 503 cooperate with the teeth on the upper surface of the toothed plate 504, causing the toothed plate 504 to move to the right relative to the electric gear 503. The toothed plate 504 moves to the right and pushes the window plate 502. Under the connection of the upper rotating shaft 501, the window plate 502 rotates to the right and opens, thus completing the oblique unfolding of the window plate 502. When it is necessary to close, the electric gear 503 is controlled to rotate in the opposite direction, thereby meshing and driving the toothed plate 504 to slide to the left, which can pull the window plate 502 to the left. Under the rotation of the rotating shaft 501, the window plate 502 rotates to the left and closes.

[0037] like Figure 2 As shown, the cross-sectional dimensions of the sealing strip 505 and the sealing seat 506 are matched. When the window panel 502 is rotated to the left to close, the sealing strip 505 at the lower end is snapped into the sealing seat 506.

[0038] like Figure 3 As shown, the length of the window panel 502 is matched with the distance between the rotating shaft 501 and the upper surface of the right top 403. The position of the electric gear 503 is fixed, so that the toothed plate 504 moves to the right relative to the electric gear 503. The toothed plate 504 moves to the right and pushes the window panel 502. Under the connection of the upper rotating shaft 501, the window panel 502 rotates to the right and opens, thus completing the oblique unfolding of the window panel 502.

[0039] Specifically: The semi-circular left top 401 and right top 403 allow sunlight to effectively enter the greenhouse from different directions. Simultaneously, the semi-circular glass tops on both sides allow the window panels 502 to open obliquely, facilitating effective air circulation. When the window panels 502 are closed, they provide a more airtight seal. Through the configuration of the rotating shaft 501, window panels 502, electric gear 503, and toothed plate 504, when the window panels 502 need to be opened, the electric gear 503 is controlled to rotate under the drive of a motor. The electric gear 503, through the meshing of its teeth on the outer wall, drives the toothed plate 504. The position of the electric gear 503... The toothed plate 504 is fixed, causing it to move to the right relative to the electric gear 503. The rightward movement of the toothed plate 504 pushes the window plate 502, which rotates to the right under the connection of the upper rotating shaft 501 and opens, thus completing the oblique unfolding of the window plate 502. When it is necessary to close, the electric gear 503 is controlled to rotate in the opposite direction, thereby engaging and driving the toothed plate 504 to slide to the left, which pulls the window plate 502 to the left. Under the rotation of the rotating shaft 501, the window plate 502 rotates to the left and closes, so that the sealing strip 505 at the lower end is embedded in the sealing seat 506, achieving the sealing effect of the opening of the window plate 502.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
