Technical Field

[0001] The invention relates to the technical field of greenhouse planting, and in particular to a heat storage and release type greenhouse planting shed. Background Art

[0002] Current greenhouses generally do not have heat storage and release functions. When the temperature in the greenhouse is high in summer or low in winter, a temperature control system, such as air conditioning, is used to keep the temperature in the greenhouse at the required planting temperature. This temperature control system really wastes resources. Summary of the invention

[0003] The purpose of the present invention is to provide a heat storage and release greenhouse for growing plants in view of the defects and shortcomings of the prior art, which can effectively solve the above-mentioned technical defects.

[0005] The geothermal pump system is arranged inside the greenhouse frame; the buried pipes in the geothermal pump system are arranged in an "S" shape structure and are alternately distributed underground inside the greenhouse frame.

[0006] With the above design, a geothermal heat pump system is arranged inside the greenhouse frame. In summer or during the day, the heat in the greenhouse is transferred to the water in the underground pipe through the heat pump unit in the geothermal heat pump system, and then discharged into the underground soil, thereby reducing the temperature in the greenhouse. In winter or at night, the water in the underground pipe absorbs heat from the underground soil, and the heat is raised by the heat pump component in the geothermal heat pump system and supplied to the greenhouse, thereby raising the temperature in the greenhouse.

[0007] When it is necessary to ventilate the finished products in the greenhouse or harvest them on a large scale, the covering film is separated from the greenhouse frame, and multiple greenhouse steel frames are manually pushed and stacked to one side of the greenhouse wall. At this time, the entire greenhouse is exposed, which is convenient for multiple people or large equipment to enter; it is also convenient for the inspection and maintenance of the geothermal pump system installed inside.

[0008] Preferably, the outer sides of the two side support masonry seats are each provided with an "L"-shaped movable guide groove, and the lower end of the greenhouse steel frame is movablely arranged in the "L"-shaped movable guide groove, and guide rollers are installed in the installation grooves opened on the inner sides of the lower ends of several of the greenhouse steel frames using rotating shafts, and the guide rollers are rollingly arranged in the rolling grooves in the vertical walls of the "L"-shaped movable guide grooves.

[0009] By adopting the above design scheme, when the greenhouse steel frame is pushed, the rolling effect of the guide roller is utilized to reduce friction and facilitate movement.

[0010] Preferably, both ends of several of the buried pipes are penetrated by connecting hoses, which pass through the suspension frame and are connected to the two delivery hoses, and the other ends of the two delivery hoses are connected to the heat pump unit in the geothermal pump system; the upper curved portion of the buried pipe is installed on the bottom of the suspension frame by means of a suspension ring; the suspension frame is arranged in an "concave"-shaped structure, and its two ends are mounted in suspension grooves opened on the side support masonry seat and the middle support masonry seat.

[0015] By adopting the above technical solution, the horizontal irrigation pipe plays a role of lateral support for the greenhouse steel frame, effectively increasing the overall firmness, while also being able to achieve integrated water and fertilizer irrigation for plants grown in the greenhouse.

[0016] Preferably, an arc-shaped guide rail is fixed on the outer arc-shaped wall of the greenhouse steel frame, a counterweight shaft is movably arranged in the arc-shaped guide rail, both ends of the counterweight shaft are connected with springs by means of fixing rings, and the other end of the spring is connected to the lower edge of the film.

[0018] By adopting the above design scheme, the film is detachably connected to the counterweight shaft by a spring, which makes it easy to separate the film from the greenhouse steel frame and the greenhouse wall, and facilitates the pushing and stacking of the greenhouse steel frame; at the same time, counterweight shafts of different weights can be selected according to environmental factors and installed on the arc guide rail to pull the film, and the counterweight shaft is positioned on the arc guide rail by using locating pins to increase the firmness of the film covering; when the film needs to be wound, the locating pin is pulled out, the film hoisting motor is turned on, and the film roller is driven to rotate, so that the film is wound on the film roller. During the winding process, the counterweight shaft moves upward in the arc guide rail to guide the film and prevent the film from shifting during the winding process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The geothermal heat pump system can control the temperature inside the greenhouse and the soil temperature, achieve heat storage and heat release, and effectively adjust the temperature inside the greenhouse and the soil;
