Description

Technical Field

[0001] The utility model provides a greenhouse, in particular to a planting greenhouse with a double ventilation mode. Background Art

[0002] Good ventilation conditions are essential in the greenhouse farming process. To facilitate air circulation inside the greenhouse, ventilation equipment is usually installed inside the greenhouse or fixed ventilation ports are reserved. At the same time, existing greenhouses are powered by external power transmission lines. Common fixed ventilation ports cannot control the air intake volume. Ventilation equipment without filtration will reduce ventilation effects and damage equipment due to dust accumulation at the air intake of the equipment. At the same time, long-term external power supply will increase operating costs.

[0003] In this regard, Chinese utility model patent specification CN219803118U discloses a greenhouse ventilation device that utilizes photovoltaic power generation. The solar panels fixedly installed on the roof provide power for the electrical equipment in the greenhouse. At the same time, a cleaning component and a blower are installed at the air intake on the left side of the greenhouse, and a fan is installed on the right side of the greenhouse to extract air. However, due to the fixed angle of the solar panel, the solar energy utilization efficiency is low. At the same time, the cleaning component is located inside the equipment, the structure is relatively complex and difficult to maintain, and natural wind cannot be used to achieve ventilation in the greenhouse, so its practicality is poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the utilization efficiency of solar energy on the top of the greenhouse is low, the structure of the ventilation and dust removal device is complex and it is impossible to use natural wind to achieve ventilation in the greenhouse. In view of the shortcomings of the existing technology, a dual ventilation mode planting greenhouse is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A planting greenhouse with dual ventilation modes, comprising a hydraulic rod and an electric control room, wherein the electric control room is provided with a battery and a control cabinet, and further comprising a planting greenhouse, a solar panel, a ventilation device, a roller motor, a windshield cloth, a support seat, a slideway and a counterweight rod, wherein the upper and lower ends of the solar panel are respectively connected to the inclined roof of the planting greenhouse and the top of the hydraulic rod through a rotating shaft, the solar panel is electrically connected to the electric control room, the hydraulic rod is electrically connected to the electric control room, the ventilation device is located on the roof facade of the planting greenhouse, the ventilation device comprises a ventilation fan and a filter, and the The ventilation fan is vertically installed inside the ventilation device, the filter is horizontally installed inside the ventilation device, the ventilation fan is electrically connected to the electric control room, the wind shield cloth is rolled on the roller of the roller motor and the lower end is connected to the counterweight rod, the support seat is fixed to the inner surface of the sloping roof of the planting greenhouse, the hydraulic rod is connected to the support seat through a rotating shaft, the bottom of the slide is hollow and the top edge is provided with screw holes for fixing to the inner surface of the sloping roof of the planting greenhouse, the counterweight rod slides radially along the slide, and the roller motor is electrically connected to the electric control room.

[0007] Furthermore, the ventilation fan has two working modes: forward rotation and reverse rotation.

[0008] Furthermore, the longitudinal length of the hollow portion of the bottom of the slide is equal to the length of the windshield cloth, and the transverse width of the slide is greater than the length of the counterweight rod.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Compared with the prior art, the utility model provides a planting greenhouse with dual ventilation modes. By adjusting the length of the hydraulic rods on both sides of the roof and thus adjusting the sun-facing angle of the solar panels, the maximum utilization of solar energy is achieved. When the air quality meets the standard, the lifting of the windshield cloth is controlled by a roller motor to achieve precise control of the air volume entering the greenhouse. The front and rear arc-shaped air ducts of the greenhouse can prevent dust, rain and snow from being directly attached to the fan with the wind, affecting the life and working efficiency of the fan. At the same time, the alternating forward and reverse rotation of the front and rear fans can complete the dust removal work on the filter in the air duct while completing the ventilation in the greenhouse, which has good practicality.
