Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural facilities, and more specifically relates to a greenhouse solar heat collection system. Background Art

[0002] Facility agriculture uses artificial techniques to modify natural light and temperature conditions, creating optimal environmental factors for plant and animal growth, enabling all-weather growth. Facility agriculture is a new production technology system, with environmentally safe greenhouses, livestock and poultry houses, and mushroom houses as its core facilities. Key technologies include covering materials that maximize solar energy utilization, achieving high transparency and thermal insulation in cold weather, cooling and moss prevention in summer, converting unwanted sunlight into wavelengths suitable for photosynthesis, and providing excellent dust and pollution resistance. Different facility types are designed based on the needs of different cultivated varieties, along with the selection of appropriate varieties and corresponding cultivation techniques.

[0003] Solar water heaters convert solar energy into thermal energy, heating water from low temperatures to high temperatures to meet temperature control requirements in agricultural production. Solar water heaters are categorized by structure into vacuum tube and flat plate types, with vacuum tube types being the dominant type, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters consist of a collection tube, a water storage tank, a bracket, and other components. The conversion of solar energy into thermal energy relies primarily on vacuum tubes, which utilize the principle that hot water rises and cold water sinks, creating a microcirculation of water to produce the desired hot water.

[0004] Traditional solar collectors consist of multiple vacuum tubes, each consisting of an outer tube and an inner tube. The space between the two tubes is evacuated, and the inner tube is coated with a heat-absorbing layer. Sunlight passes through the outer tubes and hits the heat-absorbing layer, absorbing the solar heat. This existing collector structure is complex, heats up slowly, and the vacuum tubes require support and fixing, making installation and use difficult and expensive. Maintenance is also difficult and expensive. Utility Model Content

[0005] In view of this, the utility model provides a greenhouse solar thermal collection system, which has the advantages of simple and compact device structure, low manufacturing cost, low manufacturing difficulty, low maintenance cost, light weight, faster and more efficient heating. It can solve the problems of traditional solar collectors that are inconvenient to install and use due to complex and numerous device structures, high manufacturing cost, great manufacturing difficulty, high maintenance cost, heavy weight, and slow heating.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A greenhouse solar heat collection system comprises: a main board, on which a water channel is arranged in a serpentine shape, the water inlet of the water channel is arranged on the upper left side of the main board, and the water outlet of the water channel is arranged on the lower right side of the main board; a fixing device, wherein a plurality of fixing devices are arranged around the main board; and an external device, wherein the water inlet and the water outlet of the water channel are both provided with external devices.

[0008] Furthermore, the fixing device includes a movable positioning component and a fixed positioning component, and the movable positioning component and the fixed positioning component are both arranged around the main board.

[0009] Furthermore, the movable positioning assembly includes positioning slots, and the positioning slots are provided at the four edges of the main board, and the main board can be fixedly docked with an external device through the positioning slots.

[0010] Furthermore, the fixing and positioning assembly includes a plurality of fixing through holes, and the plurality of fixing through holes are provided at the four edges of the main board, and the main board can be fixedly docked with external devices through the fixing through holes.

[0011] Furthermore, the external device includes a locking protrusion, and the outer walls of the pipes at the water inlet and the water outlet are provided with a plurality of the locking protrusions, and the locking protrusions are used to dock with the external pipe.

[0012] Furthermore, the shape of the waterway is winding.

[0013] Beneficial effects of the utility model:

[0014] The device has a simple and compact structure, low manufacturing cost, low manufacturing difficulty, low maintenance cost, and light weight. The setting of multiple bends in the waterway increases the length of the waterway, so that the water heats up faster under the same sunlight conditions. The setting of the positioning chute and the fixed through-hole makes the device easier to install. The setting of the locking protrusion strengthens the stability of the connection between the external pipe and the waterway. BRIEF DESCRIPTION OF THE DRAWINGS
