Description

Installation and use method of side wall type rolling quilt mechanism in solar greenhouse

technical field

The invention belongs to the scope of facility agriculture, and in particular relates to a method for installing and using a "side wall type roll-up mechanism" in a solar greenhouse.

Background technique

The solar greenhouse is an original energy-saving modern agricultural protection cultivation facility in China. It is a non-heating greenhouse. Compared with the traditional heating greenhouse, it has the characteristics of good lighting and good heat preservation. Not only the light and heat during the day come from Solar radiation, and the heat consumption at night mainly comes from indoor heat storage during the day. Even in the coldest winter, it can maintain a certain indoor temperature level to meet the needs of the growth of vegetables and other crops. It has been widely used. Due to the rise and use of solar greenhouses for a short period of time, the construction and use technologies still need to be further improved.

The reason why the solar greenhouse has a good thermal insulation effect is closely related to the thermal insulation effect of the outer layer of the film covered with a layer of thermal insulation quilt. The solar greenhouse is generally facing south from the north, oriented from east to west. The east, west and north sides are enclosure insulation walls, the east and west are side walls, and the front slope is covered with lighting plastic film. In order to adjust the temperature in the greenhouse in cold seasons, night It needs to be covered with a layer of insulation quilt on the outside of the film. The insulation is rolled up after sunrise to use sunlight to heat up and meet the needs of plant growth, and it is put down at sunset to reduce indoor heat radiation and maintain temperature. Rolling up and putting down such a heavy thermal insulation quilt has become an important and arduous daily work, so various quilt rolling mechanisms have emerged as the times require, which greatly reduces the intensity of physical labor and saves labor costs.

The installation and operation methods of the roll-quilt mechanism are varied. For example, the commonly used design of "side wall type roll-up mechanism" is to use the support function of the side wall of the solar greenhouse, which is composed of roll-up motor, gearbox, fixed support rod, sliding support rod, insulation roll-up rod and other parts. The motor rotates forward or reverse to roll up and put down the insulation quilt along the wall, and the suitable length is preferably no more than 70 meters. The supporting rods of the rolling quilt mechanism are located on the side of the greenhouse. The overall structure is simple, the cost is moderate, and the operation is safe. There are also obvious shortcomings in actual operation:

(1) The volume is not neat and the operation is not flexible enough. Because the solar greenhouse has a large span, about 50 to 70 meters long in the east-west direction. When rolling sideways, the thermal insulation is rolled into a cantilever structure. The side close to the motor presses the wall tightly, and the thermal insulation is rolled tightly. The diameter of the cross section is small; the pressure of the rolling rod on the side away from the motor is small, the rolled insulation quilt is loose, and the rolled cylindrical cross section has a larger diameter. Therefore, it is inevitable that the rolling speed in the east-west direction is inconsistent, and the rolled-up heat preservation quilt is not neat, and the tightness is inconsistent.

(2) The force is unbalanced and the running state is unstable. During the process of unwinding the thermal insulation quilt, due to the difference in the tightness of the thermal insulation quilt on the east and west sides, the frictional pull of the same size and the same direction cannot be generated on the thermal insulation quilt rolling rod, but it will produce a level opposite to that of the motor. Pulling force, pulling the support rod to approach the side wall, and the insulation being rolled up on the insulation rod is constantly approaching one end of the motor, so that the motor will contact the side wall over time, thereby preventing the up and down movement, lightly gnawing the corner, Seriously cause it to fail to operate normally.

(3) Easy to damage the film and insulation quilt. Due to the interaction between the thermal insulation quilt roll rod and the thermal insulation quilt, the friction between the thermal insulation quilt and the film near the motor side increases, and the film is easily damaged. During the process of being rolled up, the heat preservation quilt is pulled close to the motor, so that the whole heat preservation quilt always has two pulling forces in opposite directions. The closer to the motor, the greater the pulling force, and the more serious the heat preservation is damaged.

Contents of the invention

The present invention aims at the deficiencies of the traditional "side wall type roll-up mechanism" and provides a new type of solar greenhouse "side-wall type roll-up mechanism" installation and operation method. The new solar greenhouse "side wall type rolling mechanism" is composed of rolling motors, gearboxes, fixed support rods, sliding support rods, thermal insulation rolling rods, rolling grooves, rollers and other parts. The main reason is to increase the two fixed running mechanisms of the rolling groove and the roller.

It is characterized in that the rolling groove is composed of rolling groove groove width, rolling groove upper port, rolling groove lower port, groove edge, groove depth, etc., and is prefabricated by forging and pressing of metal profiles, and its shape is the same as that of the side wall The top surface is inlaid with cement and other building materials along the top surface of the side wall and fixed inside the wall, with the notch facing upward.

It is characterized in that: the roller is composed of the width of the roller and the radius of the roller, the width of the roller is adapted to the width of the groove, and is slightly smaller, so as to be able to run in the rolling groove; the radius of the roller is related to the depth of the groove and the height of the edge of the groove, and the width of the rolling groove The groove depth of the port under the groove and the ability to hold the heat preservation rolled rod are standard.

It is characterized in that: a "rolling groove" is prefabricated in the middle of the top slope of the side wall, and a "roller" is assembled at a certain position at the connection between the insulation quilt roll rod and the gearbox, driven by the roll quilt motor and supported by the side wall , using the frictional force generated by rolling between the thermal insulation quilt roll rod and the thermal insulation quilt to drive the rollers to move up and down along the rolling groove , so as to build the operating power operation of the thermal insulation quilt rolled up and placed on the top of the greenhouse to pass the light, and put down to cover the thermal insulation mechanism to meet the technical requirements for directional, orderly, convenient and stable operation.

Beneficial effect:

(1) Strengthen the connection between the solar greenhouse and the "side wall type rolling mechanism". The traditional "side wall rolling mechanism" is not closely connected with the whole solar greenhouse. The new "side wall rolling mechanism" passes through the "rolling groove" on the wall and the "roller" on the insulation rolling rod An organic combination has been achieved.

(2) Install a " rolling groove" along the center of the slope surface at the top of the side wall, so that the insulation quilt roll rod slides up and down along the rolling groove through the rollers, so as to realize the rolling up and down of the insulation quilt, and overcome the problems caused by rolling the quilt The lateral tension of the horizontal tension leads to the left and right movement of the roll rod, maintaining the stability of the "side wall roll quilt mechanism".

(3) The " roller " is assembled at a certain position at the connection between the thermal insulation roll rod and the gearbox. The main functions are: first, the roller guides the roll rod to slide up and down in a directional manner, avoiding the obstruction and damage caused by the thermal insulation being directly driven by the roll rod to roll The second is to use the change of the radius of the roller and the depth of the groove to adjust the uneven phenomenon caused by the large natural pressure on one side of the motor and the tightness of the roll; the third is that the roller moves in the rolling groove, and the two sides are affected by the groove edge The resistance effect of the heat preservation is rolled up and the rod will not produce left and right movements, which enhances the stability of the movement.

Detailed ways

Further illustrate the specific implementation below in conjunction with accompanying drawing:

Figure 1: Schematic diagram of the traditional "side wall roll-up mechanism" structure:

The traditional "side wall roll-up mechanism" mainly consists of roll-up motor (1), gearbox (2), thermal insulation roll-up rod (3), sliding support rod (4), fixed support rod (5), ground rotation fixed point (6), power cord (7), gearbox fixed point (8) and other parts. The purpose is to put the thermal insulation quilt on the joint between the top of the greenhouse and the back slope after being rolled up, and put it down and cover it on the plastic film. Its installation steps and usage process are as follows:

1. First, determine the side wall M where the "side wall type roll-up mechanism" is installed, at a certain distance from the bottom of the side wall M (generally, the motor and gearbox of the upper end roll-up quilt are 30 cm away from the wall and the bottom of the side wall M 2/3 of the edge line on the south side of the ground is the standard) Use cement and steel to prefabricate the ground rotation fixed point (6).

2. Select and install the sliding support rod (4) and the fixed support rod (5). The fixed support rod (5) is a steel pipe with an inner diameter of 5 cm, and the lower end is connected to the ground rotation fixed point (6) by an iron pin, and the length is as close as 4/5 of the distance from the top of the side wall. The sliding support rod (4) is set on the fixed support rod (5), the width of its inner diameter shall be able to fit on the fixed support rod (5), and the length shall be 50 cm higher than the top of the side wall M and about 1 meter from the ground. Well, the place where the gearbox is to be installed on the upper part is smashed into a flat shape, and two screw fixing holes are made. After the sliding support rod (4) and the fixed support rod (5) are socketed, they should be parallel to the side wall M when they are vertical.

3. Install the coil motor (1) and gearbox (2). The quilt motor (1) and the gearbox (2) are generally special equipment, which are connected into one body through the rotating shaft and the flange, and then the base of the gearbox (2) and the fixed point of the gearbox (8) are fixed to the sliding support rod with screws (4) Upper end.

4. Wrap the bottom end of the insulation quilt on the insulation quilt roll rod (3) through a clamp, and connect it to the transmission shaft of the gearbox (2) through the connecting flange. Insulation is rolled up rod (3) length with greenhouse thing length plus the length sum that is connected with gearbox (2), and material is steel pipe, and steel pipe inner diameter is about 10 centimetres.

Rolling quilt principle: After installing all the components according to the above procedure, connect the power cord (7) to the forward and reverse power switch , and after the power is turned on, when the motor runs forward, the insulation quilt will start to roll up and move upward, due to the side wall The supporting function of M, the sliding support rod (4) freely slides upward along the fixed support rod (5), and the fixed support rod (5) rotates with the ground rotation fixed point (6), so as to realize the rolling up of the heat preservation Function, on the contrary, turn on reverse switch, reverse movement puts down insulation quilt.

Force analysis: the rotating shaft of the gearbox (2) drives the insulation quilt rolling rod (3) to rotate, and the frictional pull F1 generated between the insulation quilt rolling rod (3) and the insulation quilt rolls up and puts down the insulation quilt, and the side wall moves up and down during the up and down movement. M and the entire greenhouse surface always produce a support F2, and at the same time, as the tightness of the insulation quilt rolled up at the east and west ends changes, the force on each point of the insulation quilt roll rod (3) will change, resulting in a horizontal reverse tension F3. All the acting forces F1, F2, and F3 have limited restraint, which leads to unstable operation, such as irregular rolls, pulling the support rods to approach the side wall M, and easy damage to the film and insulation quilt.

Figure 2: Schematic diagram of the structure of the new "side wall type roll-up mechanism":

The new "side wall type rolling mechanism" is mainly composed of rolling motor (1), gearbox (2), thermal insulation rolling rod (3), sliding support rod (4), fixed support rod (5), ground rotation fixed point (6), power cord (7), gearbox fixed point (8), roller (9), rolling groove (10). The purpose is to put the thermal insulation quilt on the joint between the top of the greenhouse and the back slope after being rolled up, and put it down and cover it on the plastic film. Its installation steps and usage process are as follows:

1. First, when prefabricating the thermal insulation walls on the east, west, and north sides of the solar greenhouse, select the side wall M as the support body, and install a rolling groove (10) along the center of the slope surface on the top of the side wall M. The rolling groove (10) is inlaid along the curved surface of the top of the wall and fixed in the wall M, with the opening facing upwards, and the two sides of the groove protrude from the curved surface at different distances from top to bottom, so that the insulation is rolled rod (3) to move against the edge of the groove, without touching the top surface of the side wall.

2. At a certain distance from the bottom of the side wall M (generally, the distance between the motor and the gearbox of the upper end roll is 30 cm from the wall and 2/3 of the distance from the bottom edge of the side wall to the south side edge line is the standard) use cement and steel to prefabricate the ground Turn the fixed point (6).

3. Install the sliding support rod (4) and the fixed support rod (5). The fixed support rod (5) is a steel pipe with an inner diameter of 5 cm, and the lower end is connected to the ground rotation fixed point (6) by an iron pin, and the length is as close as 4/5 of the distance from the top of the side wall. The sliding support rod (4) is set on the fixed support rod (5), the width of its inner diameter shall be able to fit on the fixed support rod (5), and the length shall be 50 cm from the top of the side wall M and about 1 meter from the ground , the place where the upper part is prepared to install the gearbox is smashed into a flat shape, and two screw fixing connection holes are made. After the sliding support rod (4) and the fixed support rod (5) are socketed, they should be parallel to the side wall M when they are vertical.

4. Install the winding motor (1) and gearbox (2). The quilt motor (1) and gearbox (2) are generally special equipment, which are connected into one body through a rotating shaft and a flange, and then the fixed point (8) of the gearbox (2) base gearbox is fixed to the sliding support rod ( 4) Upper end.

5. Install the insulation roll rod (3) with rollers (9). The diameter of the inner hole of the roller (9) is the same as the outer diameter of the insulation rolled rod (3), and it is inserted from the end to be connected to the gearbox (2). When the groove (10) coincides with the position, it can be fixed with the small hole inserted into the iron pin on the insulation quilt roll bar (3).

6. Wrap the bottom end of the insulation quilt on the insulation quilt roll rod (3) with rollers (9) through the clamp, and connect it to the transmission shaft of the gearbox (2) through the connecting flange. Insulation is rolled up rod (3) length with greenhouse thing length plus the length sum that is connected with gearbox (2), and material is steel pipe, and steel pipe inner diameter is about 10 centimetres.

Rolling quilt principle: After installing all the components according to the above procedures, connect the power cord (7) to the forward and reverse power switch. 3) Through the roller (9) to move freely upwards along the rolling groove (10), the fixed support rod (5) rotates with the ground turning the fixed point (6), and the sliding support rod (4) moves along the fixed support rod (5) Slide up to roll up the heat preservation quilt, otherwise turn on the reverse switch, and then move in reverse to put down the heat preservation quilt.

Force analysis: the rotating shaft of the gearbox (2) drives the insulation quilt rolling rod (3) to rotate, and the frictional pull f1 generated between the insulation quilt rolling rod (3) and the insulation quilt rolls up and puts down the insulation quilt. During the up and down movement, the side wall M and the entire greenhouse surface always produce a support f2, and the rolling groove (10) produces resistance f3 to constrain the horizontal reverse movement force generated by the thermal insulation roll rod (3) on the roll quilt, and all the forces f1, f2, and f3 are Concentrated on the rollers (9) and rolling grooves (10), the restraint is greatly enhanced, thereby maintaining the stability of the entire "side wall roll-up mechanism" and overcoming the problems caused by the traditional "side-wall roll-up mechanism". Bad phenomena such as irregular rolls, pulling the support rods towards the side wall M, and easily damaged film insulation quilts.

Due to the supporting effect of the groove edge (16) and the roller (9), it overcomes the irregularity and sliding phenomenon of the east and west ends of the quilt caused by the large natural pressure of the end of the thermal insulation quilt roll rod (3) close to the motor.

Groove depth (17) is connected with groove limit (16) and roller (9), and the most shallow part of comprehensive design should be at 10 centimetres.

Groove width H (11) adapts with roller width L (14), so that roller (9) is done freely to move up and down along rolling groove (10).

2. The roller (9) is composed of the roller width L (14) and the roller radius R (15). The roller (9) is a hollow cylinder, the middle of which is hollowly inserted into the insulating quilt roll rod (3), so as to be connected with the quilt roll motor (1) and the gearbox (2) to transmit rotational power.

Roller width L (14) is compatible with groove width H (11), slightly smaller, subject to being able to run freely in rolling groove (10); roller radius R (15) is related to groove depth (17) and groove edge ( 16) The height is related, with the groove depth (17) of the lower port (13) of the rolling groove and the ability to hold the heat preservation rolled rod (3) as the standard.
