Description

Technical Field

[0001] The utility model relates to the technical field of grape greenhouses, in particular to a grape planting greenhouse with automatic temperature regulation. Background Art

[0002] The greenhouse is composed of bamboo poles, cement poles, light steel pipes or pipes as the framework, columns, pull rods, arch rods and pressure rods, covered with plastic film to form an arched material shed. With the development of production, the application of greenhouses has become more and more extensive. Currently, greenhouses have been used for potted flowers and cut flowers; fruit tree production is used to cultivate grapes, strawberries, watermelons, melons, peaches and citrus.

[0003] During the use of grape greenhouses, they can generally only perform simple ventilation. In the hot summer and cold winter, in order to ensure the normal growth and fruiting of grapes, the temperature inside the greenhouse needs to be kept in different ranges and relatively stable. Traditional greenhouses cannot automatically adjust the internal temperature. When there is a large temperature difference between the inside and outside of the greenhouse, corresponding cooling or heating measures need to be taken manually, which has a certain impact on the growth of grapes. Based on this, a grape greenhouse with automatic temperature regulation is proposed to solve the above problems. Utility Model Content

A water tank and a cooling water tower are arranged at the other corner of the greenhouse body close to one end of the control box. The water tank is connected with the cooling water tower, and a plurality of heating pipes are arranged inside the water tank.

The control box in this scheme also includes a relay for controlling the power-on of the relevant circuits, and the PLC controller is directly electrically connected to the above relay.

A water tank 7 and a cooling water tower 6 are arranged at the other corner of the greenhouse body 1 close to one end of the control box 9. The water tank 7 is connected to the cooling water tower 6, and a plurality of heating pipes 5 are arranged inside it. A liquid pump 8 is arranged on one side of the water tank 7, which is connected to one guide pipe 14, and the other guide pipe 14 is connected to the cooling water tower 6.

[0025] One end of the four axial flow fans 3 protrudes from the two end surfaces of the greenhouse body 1, and the four axial flow fans 3 are placed side by side in pairs. The four axial flow fans 3 are provided with an electric push rod 2 at one end protruding from the greenhouse body 1. The output ends of the four electric push rods 2 are respectively fixedly connected to the top surfaces of the four baffles 4. As an optional technical scheme of the utility model, it is convenient to arrange the four axial flow fans 3 at the two end positions of the greenhouse body 1 respectively. When the axial flow fans 3 are powered on, the air flows along the length direction of the greenhouse body 1, which is convenient for ventilating the interior of the greenhouse body 1. At the same time, the electric push rods 2 are convenient for driving the baffles 4 to move respectively. When ventilation is required, the electric push rods 2 shorten the action to release the baffle 4 from blocking the ends of the four axial flow fans 3; when ventilation is not required, the electric push rods 2 extend the action to block the end positions of the axial flow fans 3 to prevent air circulation and achieve heat preservation inside the greenhouse body 1.

At the same time, the air outlet of the centrifugal fan 17 faces the industrial radiator 16, which makes it easier for the air to pass through the cooling fins outside the industrial radiator 16, and heat or reduce the air inside the greenhouse body 1 through heat exchange, so that the air inside the greenhouse body 1 is in a range that is conducive to the growth of grapes.

[0028] The four air outlets 15 are all hollow rectangular in shape and are placed tilted upward. As an optional technical solution of the utility model, this makes it easier for air to circulate diagonally upward while preventing hot air from rising and accumulating at the top of the greenhouse body 1. At the same time, the centrifugal fan 17 is inside the greenhouse body 1, which makes it easier to drive the air inside the greenhouse body 1 to be in a circulating state.

[0029] The control module includes a PLC controller, which is electrically connected to the first temperature controller 12 and the second temperature controller 10 through wires. As an optional technical solution of the present invention, the control box 9 also includes a relay for controlling the power-on of the relevant circuits, and the PLC controller is directly electrically connected to the above-mentioned relay. When the external temperature differs from the set values ​​of the first temperature controller 12 and the second temperature controller 10, the first temperature controller 12 and the second temperature controller 10 will send a high level to the PLC controller, so that the PLC controller sends an action signal to the corresponding relay, so that the coil inside the relay is energized, thereby controlling the centrifugal fan 17, the cooling water tower 6, the liquid pump 8 and the heating tube 5 to be energized.

[0030] The following steps are required when using the automatic temperature-regulated grape growing greenhouse:

When the temperature changes, the centrifugal fan 17 corresponding to the controller is powered on to make the air inside the greenhouse flow through the industrial radiator 16, so as to heat or cool the outflowing air and realize automatic regulation of the temperature inside the greenhouse.

[0033] In summary, when the user uses it, by setting up a water tank 7, a cooling water tower 6, a liquid pump 8, two guide pipes 14 and four industrial radiators 16, they are combined into a closed-loop water flow channel. When there is a certain gap between the outside temperature and the temperature inside the greenhouse, the second temperature controller 10 controls the operation of one of the heating pipes 5 or the cooling water tower 6 through the control module 18, and at the same time, the liquid pump 8 is powered on to pump the liquid in the water tank 7 along a guide pipe 10 to the four industrial radiators 16, and then flows back to the water tank 7 through another guide pipe 10, and the first temperature controller 12 is responsible for measuring the air temperature around it. , and respectively control the corresponding centrifugal fans 17 to operate, so that the air flows through the industrial radiator 16 for heating or cooling, automatically adjusts the temperature inside the greenhouse body 1, reduces manual labor, and realizes automatic control, effectively solving the problems existing in the prior art, and then arranges four axial flow fans 3, and respectively locates at the two end positions of the greenhouse body 1, and the four electric push rods 2 shorten the action, so that the baffle 4 releases the obstruction of the axial flow fans 3, and the four axial flow fans 3 are powered on and run, which is convenient to drive the air to flow along the length direction of the greenhouse body 1, thereby performing ventilation operation on the inside of the greenhouse body 1, which is convenient for the growth of grapes.
