Description

MOTORIZED REDUCTOR WITH SMART, MONOBLOCK AND COMPACT

OPEN/CLOSE SYSTEM

TECHNICAL FIELD

The invention relates to a motorized reductor having a smart, monoblock and compact opening and closing system adjustable automatically than the manually operated system used in opening and closing systems of the greenhouse windows, wherein the motorized reductor is driven by alternative current electrical motor, its exchange ratio is provided by reductor, it comprises reductor on-ff system with motorized opening and closing mechanism with monoblock and compact structure, and is used in converting high motor speeds to desired low speed levels by means of reductor gear system, in allowing on-of system to facilitate open and close in desired amounts, in allowing on-off mechanism to electronically protect the system, in turning on and shutting-off the motor, in providing opening and closing of greenhouse windows at desired positions, in interruption of the system in case of problems during the opening and closing of greenhouse windows, in providing excitation with audio and visual warning, in providing operator control during opening and closing of greenhouse windows as well as remote control.

PRIOR ART

Reductors are gear systems that change the speed-to-torque ratio of a rotational movement by means of gears. In terms of structure, gearboxes are systems comprising gear wheels, shafts, bearings and similar parts disposed in a housing. As another description, reductors are closed gear apparatus designed to reduce the high rotational speeds generated by electric motors or another different driving source to the rotation speeds required by the machine or the system where they will be used.

In greenhouses used for vegetative production, greenhouse interiors should be kept within a certain temperature and moisture range according to the weather conditions. For this purpose, greenhouses are ventilated at certain times by opening/packing their sides or tops. And in greenhouse ventilation, motorized reductors are used for packing the cover of greenhouse. In the current situation, reductors used in greenhouses are usually operated coupled to switch mechanism and motor in manually adjusted opening and closing. The fact that motors, reductors and switches are not suitable for the construction of greenhouse increases the problems. Improper installation of the construction of the greenhouse or settlement of the earth in time causes warping in the construction of the greenhouse in case of adverse conditions such as floods, etc. Moreover, even in the correctly installed greenhouses, negative conditions such as wear, corrosion, etc. which may occur in time in the rack and pinion opening closing mechanisms, may damage the motorized switched reductors.

In the prior arts' motorized reductors, which are used to control the opening and closing mechanism of greenhouses; motor, reductor and on-off system are structures separately assembled in different housings and then brought together. Disadvantages of this system are as follows:

For motors; motors, which are installed in coupling with reductor housings, can lead to many problems due to the entrapment of the mechanical shaft in the construction of the greenhouse. Motor burning resulting from excess current (as motor protection system is not specific for the system) is one of the common problems in greenhouses. Standard production of motors and thus their failure to meet the required conditions of the greenhouse construction, their insufficient starting torque, risks with regard to insulation due to the interaction of the ventilated interior with the exterior are drawbacks of the prior art.

For opening/closing system with switch mechanism; opening and closing operations are conducted at a single adjustment in systems already used in national and international greenhouses. This necessitates the adjustment of each motorized switched reductor manually in cases where a different opening/closing adjustment is desired under required conditions. Due to the mechanical design of the switch mechanism, it cannot be adjusted according to the angle of solar rays, weather conditions such as wind. This leads to inefficiency in greenhouses. Low switch precision causes experiencing overlapping and lowering of the construction in opening and closing operations. Problems like breakage of the mechanical parts of the switch occur frequently and this leads to serious troubles. Difficulties with cohesion of the switch spring and inability to fulfill its function shortly against high current are among the most common problems. In an entrapped construction, it may even lead to breakage of reductors, warpage of gears and even more seriously, collapse of the greenhouse construction without giving an opportunity to the thermal fuse to blow. All these problems revealed the need for both mechanical and electronic R&D activities for switches. For reductors; preference of reductors of proper power without considering weights of windows used in greenhouses is one of the mostly experienced problems. At present, due to the problems such as heavy and cumbersome structure of reductor housings used in national and international greenhouses, their design lacking engineering calculations and incorrect selection of desired gear systems cause breakage of reductor housings and gears. Its weight is not suitable for transportation in reductor selection and production and lost of blockage of the system in gear reductors in time can lead to serious problems. Due to breakage of reductor gears, bigger sizes of reductor housing, noisy and vibrating structure, it establishes ground for undesired adverse effects in greenhouses.

The following are some of the troubles experienced in the prior art with aforementioned embodiments:

• Breakage of reductor from the main body part and installation positions because of weak, heavy and cumbersome structure of the coupled housing,

Demolition of greenhouse construction,

Motor burning,

Experience of adverse situations such as reductor housing breakage, sealing problem, bearing strength,

Breakage of reductor gears,

Experience of adverse conditions such as failure of switches, breakage of mechanical parts etc.,

Severe problems due to non-blowing of thermal fuses in electric panels,

Failure of motors with reductors vulnerable to moisture and temperature,

Adverse effects on greenhouse construction with vibrations,

Undesired high levels of sound,

High costs of greenhouse construction due to heavy structure of coupled housing.

As a result, existence of the above problems and inadequacy of the existing solutions necessitated an improvement in the technical field of the greenhouse reductors.

Figure 2 is a view of the motorized reductor (A) of the invention with a smart, monoblock and compact opening and closing system in exploded/disassembled form. Said motorized reductor mainly comprises a motor group (2), motion transmission/gear groups (3, 4, 5, 6), a magnetic or optical detecting sensor (7), an electrical or electromechanical control group (8) located in a monoblock housing (1). Said motorized reductor (A) is in a compact structure, monolithic with the monoblock housing (1), under high control and protection by the control group (8) and has a high strength, light weighted and aesthetic construction.

In the motorized reductor (A) according to the invention; the motor group (2), the motion transmission/gear groups (3, 4, 5, 6), and the control group (8) having the opening and closing mechanism are disposed in the monoblock housing (1) as a single high strength structure. The motor group (2) is located in a motor bedding (1.3) section formed in the monoblock housing (1). The motion transmission/gear groups (3, 4, 5, 6) are also located in a reductor bearing (1.4) section formed in the monoblock housing (1). And the control group (8) is placed in a control group bedding (1.5) section formed on the upper side of the monoblock housing (1) (Fig. 3).

Following the positioning of all mechanical elements inside the said monoblock housing (1), it is closed by a motor cover (1.1) from the side of the motor group (2) and by a reductor cover (1.2) from the side of the motion transmission/gear groups (3, 4, 5, 6).

Motor group (2) is of a controllable high-class having motor protection, can communicate with the control group (8) and the motion transmission/gear groups (3, 4, 5, 6), has a non-standard distinctive shaft and high starting torque, and is suitable for design specific compact structure with regard to motor, stator and rotor.

Motion transmission/gear groups (3, 4, 5, 6), as a force transfer element, convert speed and moment of the motor to desired speed and force levels, reduce motor speeds of 800-1400 and bring the output moment to about 600 Nm and speed to 3-4. While existing switched motorized reductors used in greenhouses have varying weights around 30 kg, system of the motorized reductor (A) of the present invention is provided to be around 18 kg with motion transmission/gear groups (3, 4, 5, 6), motor group (2) and control group (8) designed by us. Together with compactness, the gears have smaller sizes, high strength and precision teeth and gripping angles.

The control group (8) can be adjusted according to the minimum and maximum requirements by means of screw speed in the mechanical system with electromechanical screw. Distance adjustment at the upper handles can be done with manual opening adjustment, detection is made by contact electrical detector instead of switch. Opening and closing mechanism limit adjustment is made by potentiometer and most importantly, the system is protected by an electronic circuit with current protection. The control group (8) of the invention, end of which is switchless in electromechanical screwed mechanical system, enjoys weekly working schedule, temperature and moisture control, current protection, limit control, entrapment control and position control with electronic circuit card.

The instantaneous speed of the motor is measured by the sensor (7). Said sensor (7) can sensitively detect the gauss field of the rotating shaft with its magnetic feature and detect black and white line as in an encoding system with its lighting feature.
