Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural greenhouse equipment technical field, concretely relates to a sawtooth type heat preservation greenhouse. BACKGROUND

[0002] The heat preservation greenhouse, also known as a greenhouse, is a kind of facility that can transmit light and keep warm, and is used for cultivating plants. In seasons that are not suitable for plant growth, it can provide a temperature environment required for plant growth, and is mostly used for cultivating or seedling of vegetables, flowers, trees and other plants that like warm in low temperature seasons. The types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses and the like. The greenhouse made of plastic film and framework is widely used due to its simple structure, good heat preservation effect and low construction cost.

[0003] For example, the patent document with publication number CN 108142164A discloses a greenhouse heat preservation greenhouse, which comprises a greenhouse body frame and a heat preservation layer. The greenhouse body frame comprises a stand column, an arch rod, a top rod and a longitudinal pull rod. The heat preservation layer comprises a fixed heat preservation layer fixedly connected with the arch rod and a movable heat preservation layer movably connected with the stand column. The greenhouse body frame is provided with a track, and the track is provided with a sliding block. The sliding block drives the movable heat preservation layer to move back and forth along the track. The inner side of the greenhouse body frame is provided with a sensor, a PLC control system and a driving system. The driving system controls the stepping motor, so that the stepping motor drives the sliding block to move back and forth along the track. The technical scheme sets the track on the greenhouse body frame, installs the sliding block on the track, and drives the sliding block to move back and forth along the track by the stepping motor. Only the PLC control system needs to be connected, and the sliding block can be controlled to move up and down by the motor, thereby reducing the labor intensity of the laborers.

[0004] The above technical scheme can realize automatic movement of the heat preservation layer and improve the convenience of greenhouse operation. However, the greenhouse is usually built by using a single body frame at present, which limits the space area in the greenhouse and is not conducive to large-area planting of crops. Moreover, when the existing greenhouse is ventilated, a ventilation opening is usually formed in the side wall of the greenhouse for ventilation. When the area of the greenhouse increases, the space inside the greenhouse increases significantly, so that the hot air inside the greenhouse cannot be quickly discharged through the ventilation opening in the side wall of the greenhouse, thereby affecting the ventilation and cooling efficiency of the greenhouse. UTILITY MODEL CONTENTS

[0005] The utility model intends to provide a sawtooth type heat preservation greenhouse to solve the technical problems of small space area of the greenhouse and low ventilation efficiency in the greenhouse in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sawtooth-type heat-insulating greenhouse, comprising multiple greenhouse frames arranged side by side, with adjacent frames interconnected; each greenhouse frame includes a top arch frame and end frames, the top arch frame being located at the top of the greenhouse frame, the end frames at both ends of the extending direction of the greenhouse frame, and side frames located on the sides of the greenhouse frames on both sides of the heat-insulating greenhouse, the side frames being located on the side of the greenhouse frame away from the adjacent greenhouse frame, and side windows being provided on the side frames; the top arch frame includes a first arch frame and a second arch frame, the first arch frame and the second arch frame being distributed facing each other on both sides of the top of the greenhouse frame, with a top window provided between the first arch frame and the second arch frame, the first arch frame, the second arch frame, the side frames, the end frames, the top window, and the side windows all covered with a film, a first film roller being provided on the side frames, and a second film roller being provided on the top window, the first film roller and the second film roller being used to roll up or unroll the film of the side window and the top window.

[0007] The principle and advantages of this scheme are as follows: During use, end frames are installed at both ends of the top arch frame to form the greenhouse frame. Multiple greenhouse frames are then arranged side-by-side, with side frames installed on the side walls of the greenhouse frames furthest from adjacent frames. After the frames are assembled, a film is laid sequentially on the top arch frame, end frames, and side frames to form an insulated greenhouse. When ventilation is needed inside the greenhouse, the film on the side frames and top windows is retracted, allowing windows to be opened on both sides and the top of the greenhouse for air exchange with the outside.

[0008] This design arranges multiple greenhouse frames side-by-side, ensuring sufficient area and space within the insulated greenhouse while maintaining adequate mechanical strength, thus improving its compressive strength and lifespan. Furthermore, ventilation windows are installed on both sides of the greenhouse and at the top of each frame. These windows allow for sufficient air exchange, and when heat dissipation is needed, hot air, being less dense than cold air, can escape through the windows at the top of the frames, ensuring efficient heat dissipation.

[0009] Preferably, as an improvement, multiple supporting columns are provided between adjacent greenhouse frames, and these supporting columns are evenly distributed along the extension direction of the greenhouse frames between adjacent greenhouse frames; the supporting columns are used to support the adjacent surfaces of adjacent greenhouses. This ensures that multiple greenhouse frames can be interconnected, increasing the space inside the insulated greenhouse, while also ensuring the stability of the greenhouse frame structure between adjacent greenhouse frames under the action of the supporting columns.

[0010] Preferably, as an improvement, one side of the first arch and the second arch are respectively located on both sides of the top of the frame of the shed, and the other side of the first arch and the second arch extends to the middle of the top of the frame of the shed in an arc shape. By using two arches to form the top arch frame, it is ensured that the two sides of the top arch frame can be assembled into two complete arches, ensuring the stability of the mechanical structure of the two sides of the top arch frame.

[0011] Preferably, as an improvement, the first arch covers the side of the second arch close to the center of the top of the frame of the shed, and the height of the side of the first arch close to the center of the top of the frame of the shed is higher than the height of the side of the second arch close to the center of the top of the frame of the shed. The gap between the first arch and the second arch at the center of the frame of the shed is the top window. The top and bottom of the formed top window can be supported by the first arch and the second arch respectively, ensuring the stability of the top window structure, and avoiding damage to the arch structure of the first arch or the second arch caused by the opening of the top window, ensuring the stability of the structure of the first arch and the second arch. At the same time, the top window is opened on one side of the first arch, so that the top window can be in arc line communication with the top of the interior of the heat preservation greenhouse, ensuring that the hot air in the heat preservation greenhouse can be smoothly discharged, improving the efficiency of heat dissipation of the heat preservation greenhouse.

[0012] Preferably, as an improvement, a plurality of telescopic rods are further arranged on one side of the first arch and the second arch at the center of the frame of the shed, and the telescopic rods are uniformly distributed along the extension direction of the frame of the shed. The telescopic rods are used to drive the first arch on one side of the center of the frame of the shed to move towards the second arch. The opening size of the top window can be adjusted according to actual needs, avoiding the case that when encountering adverse weather such as strong wind and heavy rain, the vertical opening of the top window is too large, the wind resistance and other pressure received by the vertical top window increases, and the first arch above the top window cannot be effectively supported, resulting in damage to the structure of the first arch.

[0013] Preferably, as an improvement, the first film roller and the second film roller are further used to uniformly separate the film on the side window and the top window into multiple pieces along the extension direction of the frame of the shed. When the film on the side window and the top window is rolled up or unrolled, the film in each area can be independently rolled up or unrolled by the plurality of first film rollers and second film rollers, avoiding that the extension length of the film on the side window and the top window along the extension direction of the frame of the shed is too long, increasing the operation difficulty when the film is rolled up or unrolled.

[0014] Preferably, as an improvement, both sides of the top arch frame are provided with water guide channels, both ends of the water guide channels extend to both ends of the top arch frame, and drain pipes are connected to both ends of the water guide channels. The water on the top of the top arch frame can be discharged through the drain pipes under the collection of the water guide channels, avoiding the accumulation of water in the low-lying positions between the top arch frames, and increasing the pressure on the film on the top of the heat preservation greenhouse, which may cause damage to the film.

[0015] Preferably, as an improvement, the side frame is provided with an insect screen. When the film on the side window is opened for ventilation and heat dissipation, the insect screen can prevent animals such as insects from entering the heat preservation greenhouse, avoid the crops in the heat preservation greenhouse from being damaged by animals such as insects, and ensure the safety of the heat preservation greenhouse during ventilation and heat dissipation.
