The stabilizer temperature for greenhouse or greenhouse with the use of a rubber membrane

 

(57) Abstract:

The invention relates to temperature control in the greenhouse or cold frame. The design of the temperature controller for greenhouse or greenhouse includes the Executive element is a cylinder with a rubber membrane which is connected by gidroprovod with the tank-heat exchanger, suspended on a rope. The rubber membrane is useful for small displacements with little effort. Therefore, as the ventilation device applied multislot shutter consisting of two coaxial, perforated disks with the pie hole. The membrane acts on the rotary disc through an emphasis on its surface near the axis of rotation and resist only from recoil, creating a counteracting moment of forces. When this friction rotary disk on the axis of rotation can be neglected. The temperature controller is simple, cheap and convenient in operation. 3 Il.

The purpose of the invention is to simplify and cheapen the construction, while ensuring reliability, performance and N.

In Fig. 1 shows the stabilizer of Fig. 2 - tank-heat sink; Fig 3 is a section a - a in Fig. 1. In the stabilizer membrane 12 made of rubber is the Executive element. The membrane 12 closes the free end of the hollow nozzle 11 connected with the other end through the hydraulic actuator 16 with the tank - heat sink 17 is suspended on the cable 18 within a greenhouse or greenhouse away from direct exposure to atmospheric cooling air flowing through the ventilation device that accelerates the stabilization of the temperature.

Positions 11, 12, 16, and 17 form a common hermetically sealed space filled with the working fluid, the temperature change amount which is converted to stretching or compression of the membrane 12, the kinematic associated with ventilation device.

Efforts generated by the membrane, and changes in its linear dimensions with temperature fluctuations is relatively small, so as the air handling unit is used multislot curtain in the form of coaxially arranged discs 1 and 3 with washers 7 and 8, the same perforated pie holes 2 and 4. This blind is easy rotation of the rolling disk 3 and a small moving it around the circumference near the axis 6, and where ustri full overlapping any adjacent holes 2 and 4 the others combined, that corresponds to the full opening of the shutter and the maximum inflow of atmospheric cooling air inside the greenhouse or greenhouse.

Fixed disk 1 is combined with a plate inserted in the wall or cover, and rigidly connected to the axle 6 and the bracket 10.

The bracket 10 is designed for fastening membrane 12 near the axis 6 and to restrict rotation of the disc 3.

From the figures it follows that for translation blinds from fully closed to fully open enough to turn the disk 3 clockwise by the angle enclosed when fully closed the curtain between the radial axes of adjacent holes 2 and 4.

The recess 5 on the flask 10 limits the rotation of the stop 14 rigidly mounted on the movable disc 3 near the axis 6, and hence the disk 3 is above the specified angle.

The desired temperature is set by selection of the distance between the nozzle 11 and the recess 5, in which the nozzle 11 with the membrane 12 is firmly fixed through a bracket 13 relative to the stationary disk 1. When convergence 11 and 5, the initial temperature is reduced.

Return spring 15 constantly presses the membrane 12 and the plate 14 near the axis 6.

As the temperature increases beyond a given objtask for access of atmospheric cooling air.

When the temperature decrease amount of the working fluid decreases, the membrane 12 is compressed return spring 15 rotates the disk 3 counterclockwise, closing the curtain and reducing the inflow of atmospheric air.

Thus automatically stabilizes the temperature in the volume of greenhouse or greenhouse. Fluctuations in temperature relative to the original values decrease with the increase of the performance of the stabilizer.

The proposed stabilizer is easy to manufacture and use, it provides performance and reliability, insensitive to wind loads, can be made of cheap nizkoplotnykh materials.

The stabilizer temperature for greenhouse or greenhouse with the use of rubber membranes, including membrane of rubber and reservoir-heat sink, suspended from a rope inside a greenhouse or greenhouse, United gidroprovod and forming a hermetic closed cavity filled with a working fluid to convert a temperature change of its volume in the stretching or compression of the membrane, kinematically associated with ventilation device, through which in a hotbed or greenhouse comes naturally cooling air, characterized in that the quality is equally perforated pie holes of the same size, symmetric with respect to the common axis, and the membrane covers the free end of the hollow nozzle rigidly connected with a fixed disk, which is tightly connected with the other end with the tank-heat sink through gidroprovod, and constantly pressed spring return to an emphasis on the movable disc near the axis of rotation.

SUBSTANCE: method involves process and objects arranged in predetermined manner, and place planned according to relief, with geographic and other necessary factors being taken into consideration so that directions of natural air flows are corrected. Agricultural production includes complex greenhouses, heat accumulator, basin, garden, and wind shield. Air flow directed into garden is saturated with water vapors in gaseous state if increase in temperature is desirable when it is close to minimal admissible value, and in small droplet state when lower temperature is desirable. Processor functions as central controller. Objects of branches in agricultural production are selected so that objects of previous branches make raw material for objects of subsequent branches. Furthermore, joint mutually useful development of these objects at suitable conditions is possible. These conditions are created in complex greenhouse units intermediate with regard to said branches. General-purpose containers with raw material are conveyed through said complex greenhouse units. This results in multiple sequential-parallel utilization of raw materials in number of branches of industry. Method stipulates employment of useful relations between populations of organisms - objects of agricultural branches of industry: symbiosis and, according to kind of symbiosis, natural selection.

EFFECT: increased resource saving, reduced production costs of agricultural product and improved ecology of environment.
