本发明的最佳实施方式Best Mode of the Invention
本发明提供一种大棚，其中，大棚包括大棚骨架和棚膜，而为了精确的对大棚中栽种的植物进行供水，则采用埋在地面下方的滴灌管来实现，滴灌管需要满足长时间供水过程中可靠的防堵能力，这样，在大棚在搭建完成后，埋在地下的滴灌管能够保证大棚内种植物的供水要求。The invention provides a greenhouse, wherein the greenhouse includes a greenhouse skeleton and a greenhouse film, and in order to accurately supply water to the plants planted in the greenhouse, a drip irrigation pipe buried under the ground is used to realize the drip irrigation pipe needs to meet the long-term water supply process Reliable anti-blocking capacity, so that after the greenhouse is built, the drip irrigation pipe buried underground can ensure the water supply requirements for plants in the greenhouse.
针对滴灌管的改进设计，具体说明如下：For the improved design of the drip irrigation pipe, the specific instructions are as follows:
如图1-图8所示，滴灌管1包括多根输水管101和多个滴灌连接头102，而滴灌连接头102包括：连接管道11、弹性挡板12和滴水头13，连接管道11的管壁上开设有至少一个安装孔111；弹性挡板12贴靠在连接管道11的内管壁上并密封遮盖住安装孔111，弹性挡板12上与安装孔111相对的部位还开设有通孔（未标记）；滴水头13插在安装孔111中并与弹性挡板12连接，滴水头13中形成有连通通孔的进水腔体131，滴水头13的侧壁开设有与进水腔体131连通的出水口132；其中，弹性挡板12在连接管道11中水压的作用下朝向安装孔111中变形并推动滴水头13从安装孔111中伸出，以使得出水口132从安装孔111中露出，而连接管道11则采用螺纹连接或热熔焊接的方式连接在两根输水管101之间。As shown in FIGS. 1-8, the drip irrigation pipe 1 includes a plurality of water delivery pipes 101 and a plurality of drip irrigation connection heads 102, and the drip irrigation connection head 102 includes: a connection pipe 11, an elastic baffle 12 and a drip head 13, connecting the pipe 11 The tube wall is provided with at least one mounting hole 111; the elastic baffle 12 abuts on the inner tube wall of the connecting pipe 11 and seals and covers the mounting hole 111, and a portion of the elastic baffle 12 opposite to the mounting hole 111 is also opened Hole (not marked); the drip head 13 is inserted in the mounting hole 111 and connected with the elastic baffle 12, the drip head 13 is formed with a water inlet cavity 131 with a communication through hole, the side wall of the drip head 13 is provided with water inlet The water outlet 132 communicating with the cavity 131; wherein, the elastic baffle 12 deforms toward the installation hole 111 under the action of the water pressure in the connecting pipe 11 and pushes the drip head 13 to protrude from the installation hole 111, so that the water outlet 132 The mounting hole 111 is exposed, and the connecting pipe 11 is connected between the two water pipes 101 by screw connection or hot melt welding.
具体而言，本实施例滴灌连接头中的连接管道11用于输送水，水流方向如图1中的箭头所示，在实际使用过程中，当处于不供水的状态下，参考图1和图2，弹性挡板12处于原始姿态，此时，滴水头13位于安装孔111中，安装孔111的孔壁将对出水口132进行遮挡，这样，便可以避免泥沙和植物根堵在出水口132而造成出水口132淤堵。而在供水状态下，连接管道11中进入水，并且，连接管道11中的水压逐渐增大，参考图3和图4，随着连接管道11中水压的增大，在水压作用下使得弹性挡板12向安装孔111中发生形变，而由于滴水头13位于安装孔111中并连接在弹性挡板12上，弹性挡板12向安装孔111中凸出后，会带动滴水头13朝向安装孔111的外侧移动，随着连接管道11中供水水压的持续增大最终使得出水口132从安装孔111中部分露出或全部露出，此时，水便可以经过出水口132输出实现滴灌作业。在滴灌作业完成后，连接管道11中的水压逐渐下降，在此过程中，弹性挡板12依靠自身弹性复位，并同时将带动滴水头13回缩到安装孔111中，而在滴水头13回缩的过程中，出水口132始终保持出水状态，确保回水过程中泥沙不会粘附在出水口132中，而当出水口进入到安装孔111中后，出水口132又会进一步的被安装孔111的孔壁进行遮挡和保护。其中，滴水头13与安装孔111的孔壁之间的距离则根据需要设置，在保证滴水头13能够顺畅伸缩的前提下，还需要确保安装孔111的孔壁对出水口132进行有效的防堵保护，具体距离范围值，则可以根据具体的使用场景进行适应性的设置，例如：在泥土环境中使用，则距离要小一些，而在沙石环境中使用，则距离可以大一些，在此不对具体的距离范围进行限定。另外，为了增大弹性挡板12的变形量，安装孔111为阶梯型孔或喇叭形孔，安装孔111的内孔径大于安装孔111的外孔径，具体的，以采用阶梯型孔为例，安装孔111靠近连接管道11外管壁的孔体尺寸小于安装孔111靠近连接管道11内管壁的孔体尺寸，而滴水头13具有出水口132的部位则位于外侧的孔体中，在实际使用过程中，连接管道11内水压增大后，弹性挡板12能够在安装孔111靠近连接管道11内管壁的孔体中变形，而由于内侧的孔体所形成的空间较大，使得弹性挡板12具有足够的空间发生形变，从而可以增大弹性挡板12的变形量以带动滴水头13有效的伸出到安装孔111的外部以外露出出水口132。另外，针对连接管道11可以采用材质较硬的材料制成，例如可以采用PVC管等，以确保安装孔111具有足够的结构强度不会发生形变，同时，连接管道11的管壁厚度要满足在滴水头13回缩状态下，利用安装孔111的孔壁对出水口132进行遮挡，具体管壁厚度以及安装孔111的开孔尺寸，在此不做限制，本领域技术人员则可以根据实际情况进行设定和选择，以满足实际现场应用环境的要求；而弹性挡板12可以采用弹性橡胶或硅胶等具有弹性形变功能的材料制成，弹性挡板12的边缘可以采用胶粘或热焊接的方式固定在连接管道11的管壁上，例如：可以采用热熔焊接或激光焊接的方式将弹性挡板12连接到连接管道11的管壁上，在此不做限制；针对滴水头13可以与弹性挡板12为一整体结构，或者，滴水头13也采用胶粘或热焊接的方式连接到弹性挡板12。而针对滴水头13上出水口132的结构形式可以采用圆形、条形或椭圆形开口，而开口的方式可以采用沿出水方向口径逐渐增大的方式，这样，即便出水口132被泥沙遮挡，在下次供水时，利用水压配合滴水头13的形变使得出水口132中的泥沙快速排出，以提高防堵能力。Specifically, the connecting pipe 11 in the drip irrigation connector of this embodiment is used to transport water, and the direction of the water flow is as shown by the arrow in FIG. 1. In actual use, when the water is not supplied, refer to FIGS. 2. The elastic baffle 12 is in the original posture. At this time, the drip head 13 is located in the mounting hole 111, and the hole wall of the mounting hole 111 will block the water outlet 132, so as to avoid silt and plant roots being blocked in the water outlet 132 and block the water outlet 132. In the water supply state, water enters the connecting pipe 11, and the water pressure in the connecting pipe 11 gradually increases. Referring to FIGS. 3 and 4, as the water pressure in the connecting pipe 11 increases, under the effect of water pressure The elastic baffle 12 deforms into the mounting hole 111, and since the drip head 13 is located in the mounting hole 111 and is connected to the elastic baffle 12, the elastic baffle 12 protrudes into the mounting hole 111, which will drive the drip head 13 Moving toward the outside of the mounting hole 111, as the water pressure in the connecting pipe 11 continues to increase, the water outlet 132 is partially or completely exposed from the mounting hole 111. At this time, the water can be output through the water outlet 132 to achieve drip irrigation operation. After the drip irrigation operation is completed, the water pressure in the connection pipe 11 gradually decreases. In the process, the elastic baffle 12 relies on its own elastic reset and at the same time retracts the driving drip head 13 into the installation hole 111, while the drip head 13 In the process of retraction, the water outlet 132 always keeps the water state, ensuring that the sediment will not adhere to the water outlet 132 during the return process, and when the water outlet enters the installation hole 111, the water outlet 132 will further The hole wall of the mounting hole 111 is shielded and protected. Among them, the distance between the drip head 13 and the hole wall of the mounting hole 111 is set as required. On the premise of ensuring that the drip head 13 can smoothly expand and contract, it is also necessary to ensure that the hole wall of the mounting hole 111 effectively prevents the water outlet 132 For blocking protection, the specific distance range value can be set adaptively according to the specific use scenario. For example: in a mud environment, the distance is smaller, and in a sand environment, the distance can be larger. This does not limit the specific distance range. In addition, in order to increase the amount of deformation of the elastic baffle 12, the mounting hole 111 is a stepped hole or a trumpet-shaped hole. The inner diameter of the mounting hole 111 is larger than the outer diameter of the mounting hole 111. Specifically, the stepped hole is used as an example. The size of the hole body of the mounting hole 111 close to the outer pipe wall of the connecting pipe 11 is smaller than the size of the hole body of the mounting hole 111 close to the inner pipe wall of the connecting pipe 11, and the portion of the drip head 13 with the water outlet 132 is located in the outer hole body. During use, after the water pressure in the connecting pipe 11 increases, the elastic baffle 12 can be deformed in the hole body of the mounting hole 111 close to the wall of the inner pipe of the connecting pipe 11, and the larger space formed by the inner hole body makes the The elastic baffle 12 has sufficient space to deform, so that the deformation amount of the elastic baffle 12 can be increased to drive the drip head 13 to effectively extend out of the installation hole 111 to expose the water outlet 132. In addition, the connecting pipe 11 can be made of a harder material, for example, a PVC pipe, etc., to ensure that the mounting hole 111 has sufficient structural strength without deformation, and at the same time, the wall thickness of the connecting pipe 11 must meet When the drip head 13 is retracted, the water outlet 132 is blocked by the hole wall of the mounting hole 111, and the specific tube wall thickness and the opening size of the mounting hole 111 are not limited here, and those skilled in the art can use the actual situation Set and select to meet the requirements of the actual field application environment; and the elastic baffle 12 can be made of materials with elastic deformation functions such as elastic rubber or silicone, and the edge of the elastic baffle 12 can be glued or heat welded Fixed on the wall of the connecting pipe 11, for example: hot-melt welding or laser welding can be used to connect the elastic baffle 12 to the wall of the connecting pipe 11, without limitation here; for the drip head 13 can be The elastic baffle 12 is an integral structure, or the drip head 13 is also connected to the elastic baffle 12 by glue or heat welding. For the structure of the water outlet 132 on the drip head 13, a circular, strip-shaped, or elliptical opening can be used, and the opening can be gradually increased in the direction of the water outlet, so that even if the water outlet 132 is blocked by sediment In the next water supply, the water pressure and the deformation of the drip head 13 are used to quickly discharge the sediment in the water outlet 132 to improve the anti-blocking ability.
进一步的，为了更加有效的提高防堵性能，滴水头13还包括：第一密封圈133，绕滴水头13的外周分布并位于出水口132的外侧。具体的，在滴水头13回缩到安装孔111中后，第一密封圈133将对出水口132的外侧进行密封封堵，这样，更加有效的阻挡外部的泥沙进入到出水口中，而针对第一密封圈133的封堵方式有多种，例如：如图1和图2所示，第一密封圈133设置在滴水头13的侧壁上，在滴水头13回缩到安装孔111中后，第一密封圈133也位于安装孔111中，并且，第一密封圈133的边缘贴靠在安装孔111的孔壁上；或者，如图5和图6所示，第一密封圈133设置在滴水头13的外端部，在滴水头13回缩到安装孔111中，第一密封圈133位于连接管道11的外部并第一密封圈133的边缘贴靠在连接管道11的外管壁上，并且，第一密封圈133将在外侧遮盖住滴水头13与安装孔111之间的间隙。优选的，滴水头13绕其外周还设置有第二密封圈134，第二密封圈134位于出水口132的内侧，从而使得出水口132位于第一密封圈133和第二密封圈134之间，而第二密封圈134的边缘将始终贴靠在安装孔111的孔壁上，这样，在进行供水滴灌的过程中，随着滴水头13逐渐伸出安装孔111，第二密封圈134也随之在安装孔111中移动，这样，即便有泥沙进入到安装孔111和滴水头13之间，再次供水滴灌时，移动的第二密封圈134也能够将泥沙向外推出并跟随出水口132输出的水排出，进一步的提高防堵性能。Further, in order to more effectively improve the anti-blocking performance, the drip head 13 further includes: a first sealing ring 133 distributed around the outer periphery of the drip head 13 and located outside the water outlet 132. Specifically, after the drip head 13 is retracted into the mounting hole 111, the first seal ring 133 will seal and seal the outer side of the water outlet 132, so as to effectively prevent the external sediment from entering the water outlet, and There are various sealing methods of the first sealing ring 133, for example: as shown in FIGS. 1 and 2, the first sealing ring 133 is disposed on the side wall of the drip head 13 and retracts into the mounting hole 111 at the drip head 13 Afterwards, the first sealing ring 133 is also located in the mounting hole 111, and the edge of the first sealing ring 133 abuts on the hole wall of the mounting hole 111; or, as shown in FIGS. 5 and 6, the first sealing ring 133 Located at the outer end of the drip head 13, the drip head 13 is retracted into the mounting hole 111, the first seal ring 133 is located outside the connecting pipe 11 and the edge of the first seal ring 133 abuts the outer pipe of the connecting pipe 11 On the wall, and the first sealing ring 133 will cover the gap between the drip head 13 and the mounting hole 111 on the outside. Preferably, the drip head 13 is further provided with a second sealing ring 134 around its outer periphery. The second sealing ring 134 is located inside the water outlet 132 so that the water outlet 132 is located between the first sealing ring 133 and the second sealing ring 134. The edge of the second sealing ring 134 will always be in contact with the wall of the mounting hole 111. In this way, in the process of water supply irrigation, as the drip head 13 gradually extends out of the mounting hole 111, the second sealing ring 134 also follows It moves in the mounting hole 111, so that even if there is sediment between the mounting hole 111 and the drip head 13, when the drip irrigation is provided again, the moving second sealing ring 134 can push the sediment out and follow the water outlet 132 The output water is discharged to further improve the anti-blocking performance.
更进一步的，为了减少因连接管道11中流动的水中含有杂质而造成滴水头13从内侧堵塞，还包括进水部件14，进水部件14中形成多条进水通道1400，进水通道1400的进水方向与连接管道11中的水流方向倾斜且反向设置；其中，进水部件14设置在通孔中，进水通道1400连通进水腔体131，连接管道11中的水经由进水通道1400进入到进水腔体131。具体的，如图1和图2所示，连接管道11中的水流方向为实线箭头所指示的方向，而进水通道1400的进水方向为虚线箭头所指示的方向，进水方向相对于水流方向倾斜且反向设置，在供水过程中，水流流经进水通道1400的进水口处将形成降压区，使得流入到进水通道1400中的水的流速变慢，进水通道1400的中水流所夹杂的杂质跟随水流流动过程中，在受惯性作用下，杂质不容易进入到进水通道1400中，从而有效的减少因供水水流中杂质造成滴水头13堵塞的情况发生。其中，如图2和图7所示，进水部件14包括底盘141和插头142，底盘141中形成多条第一进水流道1401，第一进水流道1401的进水方向与连接管道11中的水流方向倾斜且反向设置；插头142中形成多条第二进水流道1402，插头142设置在底盘141上，第二进水流道1402与对应的第一进水流道1401连接并形成进水通道1400；其中，插头142插在通孔中，底盘141的边缘贴靠在弹性挡板12上。具体的，进水部件14由底盘141和插头142组装，底盘141和插头142可以为一整体结构，也可以采用分体式设计组装而成，插头142则***到通孔中，而底盘141作为固定部件则连接在弹性挡板12上，而底盘141与弹性挡板12的连接方式可以采用胶粘或热焊接的方式，同时，对于进水部件14而言，根据需要可以采用硬质塑料制成，而为了增大弹性挡板12的形变量，则进水部件14也采用弹性材料，例如弹性橡胶或硅胶等。另外，为了避免凸出于连接管道11内壁进水部件14对水流造成较大的阻流，底盘141面向连接管道11中的水流方向的边缘设置有倾斜导流面1411，倾斜导流面1411能够顺着水流方向倾斜，以有效的导向水流经由倾斜导流面1411顺畅的流动，同样的，弹性挡板12向连接管道11中的水流方向的边缘也可采用上述设置。Furthermore, in order to reduce the clogging of the drip head 13 from the inside due to the impurities contained in the water flowing in the connecting pipe 11, a water inlet part 14 is also formed. A plurality of water inlet channels 1400 are formed in the water inlet member 14. The water inlet direction is inclined and opposite to the water flow direction in the connection pipe 11; wherein, the water inlet part 14 is provided in the through hole, the water inlet channel 1400 communicates with the water inlet cavity 131, and the water in the connection pipe 11 passes through the water inlet channel 1400 enters the inlet cavity 131. Specifically, as shown in FIGS. 1 and 2, the water flow direction in the connecting pipe 11 is the direction indicated by the solid arrow, and the water inlet direction of the water inlet channel 1400 is the direction indicated by the dotted arrow, and the water inlet direction is relative to The direction of the water flow is inclined and set in the opposite direction. During the water supply process, the water flow will form a decompression zone at the water inlet of the water inlet channel 1400, so that the flow velocity of the water flowing into the water inlet channel 1400 becomes slower. Impurities contained in the middle water flow follow the water flow, and under the influence of inertia, the impurities do not easily enter the water inlet channel 1400, thereby effectively reducing the occurrence of clogging of the drip head 13 due to impurities in the water supply flow. As shown in FIGS. 2 and 7, the water inlet part 14 includes a chassis 141 and a plug 142. A plurality of first water inlet channels 1401 are formed in the chassis 141. The water inlet direction of the first water inlet channel 1401 is connected to the connecting pipe 11 The direction of the water flow is inclined and reversed; a plurality of second water inlet channels 1402 are formed in the plug 142, the plug 142 is provided on the chassis 141, and the second water inlet channels 1402 are connected to the corresponding first water inlet channels 1401 and form an inlet Channel 1400; wherein, the plug 142 is inserted into the through hole, and the edge of the chassis 141 abuts on the elastic baffle 12. Specifically, the water inlet part 14 is assembled by the chassis 141 and the plug 142. The chassis 141 and the plug 142 may be an integral structure or may be assembled by a split design. The plug 142 is inserted into the through hole, and the chassis 141 serves as a fixed The components are connected to the elastic baffle 12, and the connection between the chassis 141 and the elastic baffle 12 can be glued or thermally welded. At the same time, for the water inlet part 14, it can be made of hard plastic as needed In order to increase the deformation of the elastic baffle 12, the water inlet member 14 also uses an elastic material, such as elastic rubber or silicone. In addition, in order to avoid protruding out of the inner wall of the connecting pipe 11 and causing a large obstruction to the water flow, the edge of the chassis 141 facing the direction of the water flow in the connecting pipe 11 is provided with an inclined guide surface 1411. The inclined guide surface 1411 can Tilt in the direction of the water flow to effectively guide the flow of water smoothly through the inclined guide surface 1411. Similarly, the edge of the elastic baffle 12 in the direction of the water flow in the connecting pipe 11 can also be configured as described above.
通过控制供水水压的不同，便可以控制滴水头伸出的量，进而调节出水口的出水量，以达到调节滴灌的速度。另外，通过进一步的增大水压，还可以利用水压来对滴水头的出水口进行冲洗操作，在较大水压作用下，一方面出水口的出水量增大，另一方面出水口的形变量也增大，从而对于淤堵的出水口实现清理的目的。By controlling the difference in water pressure of the water supply, the amount of dripping head can be controlled, and then the amount of water out of the water outlet can be adjusted to achieve the speed of drip irrigation. In addition, by further increasing the water pressure, the water pressure can also be used to flush the water outlet of the drip head. Under the action of a large water pressure, the water output of the water outlet increases, on the other hand, the water outlet The amount of deformation is also increased, so as to achieve the purpose of cleaning up the blocked outlet.
针对大棚的棚体结构的改进设计，具体说明如下：For the improved design of the shed body structure of the greenhouse, the specific instructions are as follows:
如图9-图13所示，棚体结构2要满足对大棚内的植物进行遮挡雨水的作用，确保植物的供水仅通过种植地面下的滴灌管来精确控制。为此，棚体结构2包括：大棚骨架21、侧卷膜组件22和顶部卷膜组件23，其中，侧卷膜组件22包括竖向导轨221、第一滑动座222、第一电机223和第一卷膜杆224，竖向导轨221竖向固定在大棚骨架21的一侧，第一滑动座222可滑动的安装在竖向导轨221上，第一电机223固定在第一滑动座222上，第一卷膜杆224与所述电机的转轴连接，第一卷膜杆224上缠绕有第一棚膜（未图示），所述第一棚膜的自由端部连接在大棚骨架21的侧壁上部；顶部卷膜组件23包括顶部导轨231、第二滑动座232、第二电机233和第二卷膜杆234，顶部导轨231固定在大棚骨架21的顶部并沿大棚骨架21的顶部外形延伸，第二滑动座232可滑动的安装在顶部导轨231上，第二电机233固定在第二滑动座232上，第二卷膜杆234与所述电机的转轴连接，第二卷膜杆234上缠绕有第二棚膜，所述第二棚膜的自由端部连接在大棚骨架21的顶部；其中，大棚骨架21的每一侧壁均配置有对应的侧卷膜组件22。As shown in Figures 9-13, the shed body structure 2 should meet the role of shielding rainwater from the plants in the greenhouse, ensuring that the water supply of the plants is accurately controlled only by the drip irrigation pipe under the planting ground. To this end, the shed body structure 2 includes: a greenhouse skeleton 21, a side roll film assembly 22 and a top roll film assembly 23, wherein the side roll film assembly 22 includes a vertical guide rail 221, a first sliding seat 222, a first motor 223, and a second A roll of film rod 224, the vertical guide rail 221 is vertically fixed on one side of the greenhouse skeleton 21, the first sliding seat 222 is slidably mounted on the vertical guide rail 221, and the first motor 223 is fixed on the first sliding seat 222, The first film winding rod 224 is connected to the rotating shaft of the motor. A first film (not shown) is wound around the first film winding rod 224, and the free end of the first film is connected to the side of the greenhouse frame 21 The upper part of the wall; the top roll film assembly 23 includes a top rail 231, a second sliding seat 232, a second motor 233, and a second roll film rod 234. The top rail 231 is fixed on the top of the greenhouse frame 21 and extends along the top profile of the greenhouse frame 21 , The second sliding base 232 is slidably mounted on the top rail 231, the second motor 233 is fixed on the second sliding base 232, the second film winding rod 234 is connected to the rotating shaft of the motor, and the second film winding rod 234 A second shed film is wound, and the free end of the second shed film is connected to the top of the greenhouse frame 21; wherein, each side wall of the greenhouse frame 21 is provided with a corresponding side roll film module 22.
具体而言，大棚骨架21在顶部和侧部分别配置有可以收卷的棚膜，根据需要对棚膜进行收卷或展开。在雨天环境下，大棚骨架21在顶部和侧部的棚膜均处于展开状态，这样，通过棚膜将大棚骨架21内部罩起来，防止雨水淋到大棚骨架21的内部。一方面能够精确的控制内部植物的供水量，以满足根据植物生长需要定期定量的供水，另一方面可以保证大棚骨架21内部地表层保持干燥，以减少杂草的生长，同时，相对干燥的环境也减少虫病灾害，以减少药剂的使用量。而在非雨天环境下，则大棚骨架21在顶部和侧部的棚膜均处于收卷状态，这样，可以保证大棚骨架21内部的植物保持良好的通风和光照，以达到露天种植的效果，更有利于提高植物的生长品质。Specifically, the greenhouse frame 21 is provided with a retractable shed film on the top and the side, and the shed film is rolled or unfolded as necessary. In a rainy environment, the greenhouse membranes on the top and the side of the greenhouse framework 21 are both unfolded. In this way, the interior of the greenhouse framework 21 is covered by the greenhouse membrane to prevent rain water from entering the greenhouse framework 21. On the one hand, it can accurately control the water supply of the internal plants to meet the regular quantitative water supply according to the needs of plant growth. On the other hand, it can ensure that the surface layer inside the greenhouse skeleton 21 remains dry to reduce the growth of weeds. At the same time, the relatively dry environment It also reduces insect pest disasters to reduce the use of medicines. In the non-rainy environment, the greenhouse film on the top and side of the greenhouse frame 21 is in a rolled state, so that the plants inside the greenhouse frame 21 can be kept well ventilated and illuminated to achieve the effect of open planting, more Conducive to improving the growth quality of plants.
进一步的，由于第一棚膜在大棚骨架21顶部覆盖面积较大，为了在第一棚膜展开后，有效的定位第一棚膜，则大棚还包括压膜组件24，压膜组件24包括第三电机241、卷绕杆242和多根压膜带243，卷绕杆242可转动的安装在大棚骨架21上，所述电机与卷绕杆242驱动连接，压膜带243沿着卷绕杆242的长度方向依次排布，压膜带243的一端连接在卷绕杆242，压膜带243的一端连接在大棚骨架21上，压膜带243压在所述第二棚膜上。具体的，卷绕杆242与第一卷膜杆224均沿着大棚骨架21的长度方向延伸，而压膜带243则沿着第一棚膜的收卷展开方向布置，压膜带243压在所述第二棚膜的上方，在第一棚膜展开后，通过压膜带243能够将第一棚膜压紧在大棚骨架21的顶部。其中，通过第三电机241驱动卷绕杆242转动，能够满足第一棚膜收卷或展开的压紧要求。即在第一棚膜收卷过程中，随着第一卷膜杆224缠绕的第一棚膜的长度增加，第一棚膜的绕在第一卷膜杆224上的厚度逐渐增大，此时，第三电机241驱动卷绕杆242转动，以使得卷绕杆242上缠绕压膜带243伸展开，以满足收卷第一棚膜的要求；反正，当第一棚膜展开的过程中，则第三电机241驱动卷绕杆242反向转动，使得压膜带243收卷到卷绕杆242上，以确保压膜带243能够有效的压紧第一棚膜。而对于覆盖在大棚骨架21的侧壁第二棚膜而言，可以同样配置压膜组件24来对侧壁展开的第二棚膜进行压紧处理。而由于第二棚膜在大棚骨架21的高度尺寸不大，则可以直接在大棚骨架21的侧壁的上下两端直接连接压膜带243。Further, since the first shed film covers a large area on the top of the greenhouse frame 21, in order to effectively position the first shed film after the first shed film is unfolded, the shed further includes a membrane pressing assembly 24, and the membrane pressing assembly 24 includes the first Three motors 241, a winding rod 242, and a plurality of film pressing belts 243, the winding rod 242 is rotatably installed on the greenhouse frame 21, the motor is drivingly connected to the winding rod 242, and the film pressing belt 243 is along the winding rod The lengths of the 242 are sequentially arranged, one end of the lamination tape 243 is connected to the winding rod 242, one end of the lamination tape 243 is connected to the greenhouse frame 21, and the lamination tape 243 is pressed against the second greenhouse film. Specifically, both the winding rod 242 and the first film winding rod 224 extend along the length direction of the greenhouse frame 21, and the film lamination tape 243 is arranged along the winding and unwinding direction of the first film, and the film lamination tape 243 is pressed at Above the second shed film, after the first shed film is unfolded, the first shed film can be pressed against the top of the greenhouse frame 21 by the film pressing belt 243. Wherein, the third motor 241 drives the winding rod 242 to rotate, which can meet the pressing requirements for the first shed film to be wound or unrolled. That is, during the winding of the first film, as the length of the first film wound by the first film rod 224 increases, the thickness of the first film wound around the first film rod 224 gradually increases. At this time, the third motor 241 drives the winding rod 242 to rotate, so that the winding film strip 243 on the winding rod 242 extends to meet the requirement of winding the first shed film; anyway, when the first shed film is unfolded Then, the third motor 241 drives the winding rod 242 to rotate in the reverse direction, so that the film pressing belt 243 is wound onto the winding rod 242, so as to ensure that the film pressing belt 243 can effectively press the first greenhouse film. As for the second shed film covering the side wall of the greenhouse frame 21, the pressure film assembly 24 can be similarly arranged to perform the pressing treatment on the second shed film that is expanded on the side wall. However, since the height dimension of the second greenhouse film on the greenhouse frame 21 is not large, the pressure film tape 243 can be directly connected to the upper and lower ends of the side wall of the greenhouse frame 21 directly.
而为了降低制造成本，大棚骨架21包括四个侧壁框架211和多个顶部拱架212，四个所述侧壁框架依次首尾连接形成环形架体，所述顶部拱架212依次布置并固定在所述环形架体的上部；相邻的两个所述顶部拱架之间设置有压膜组件24。具体的，压膜组件24能够同时对两侧的顶部拱架212上的第一棚膜进行压膜处理，通过在压膜组件24的卷绕杆242向两侧分布有压膜带243，卷绕杆242能够同时对两侧的压膜带243进行松紧处理，以实现同时对两侧的顶部拱架212上的第一棚膜进行压紧处理。In order to reduce the manufacturing cost, the greenhouse skeleton 21 includes four side wall frames 211 and a plurality of top arch frames 212, the four side wall frames are connected end to end to form an annular frame body, and the top arch frames 212 are sequentially arranged and fixed at The upper part of the ring-shaped frame body; between the two adjacent top arch frames, a pressure film assembly 24 is arranged. Specifically, the lamination module 24 can simultaneously perform lamination processing on the first shed film on the top arches 212 on both sides. The lamination tape 243 is distributed to both sides by the winding bar 242 of the lamination assembly 24. The winding rod 242 can simultaneously tighten the pressure film strips 243 on both sides, so as to simultaneously perform the compression process on the first shed film on the top arches 212 on both sides.
更进一步的，大棚骨架21顶部的下边缘设置有集水槽213，集水槽213用于收集降在所述第二棚膜上的雨水，集水槽213连接有排水管214；大棚骨架21的下方还设置有蓄水池，排水管214连接所述蓄水池，所述蓄水池用于将收集的雨水输出并供给所述滴灌管。具体的，在雨天环境下，顶部第二棚膜上落下的雨水汇入到集水槽213中，以通过排水管214输送到蓄水池中进行存储。而在平时灌溉作用时，则可以利用蓄水池中的水输送到滴灌管对植物进行灌溉。Furthermore, the lower edge of the top of the greenhouse frame 21 is provided with a water collecting tank 213, which is used to collect rainwater falling on the second greenhouse film, and the water collecting tank 213 is connected with a drainage pipe 214; A water reservoir is provided, and a drain pipe 214 is connected to the water reservoir, and the water reservoir is used to output and supply the collected rainwater to the drip irrigation pipe. Specifically, in a rainy environment, the rainwater falling on the top second shed membrane is imported into the water collecting tank 213 to be transported to the storage tank through the drain pipe 214 for storage. In normal irrigation, the water in the reservoir can be transported to the drip irrigation pipe to irrigate the plants.
优选地，为了减少除草剂和杀虫剂等药剂的使用量，达到绿色环保养殖，在种植过程中，则需要保持棚体结构2内部的土层上表面保持干燥的状态，这样，一方面减少杂草的生长，另一方面由于棚体结构2内部较为干燥也减少病虫灾害。为此，棚体结构2的外周分布有挡水围板201，所述挡水围板201的下部掩埋在所述大棚的种植地面以下，所述挡水围板201的上部位于所述大棚的种植地面以上，滴灌管1掩埋在所述大棚的种植地面以下并低于所述挡水围板201的下部布置。具体的，通过在棚体结构2的外侧配置挡水围板201，能够避免在雨天环境下，棚体结构2外侧的雨水渗入到棚体结构2内的土表层，以最大限度的保持棚体结构2内的土表层保持干燥的状态。Preferably, in order to reduce the use of herbicides and insecticides and other green chemicals, to achieve green farming, during the planting process, it is necessary to keep the upper surface of the soil layer inside the shed structure 2 dry, thus reducing The growth of weeds, on the other hand, reduces the pests and diseases due to the relatively dry interior of the shed structure 2. For this reason, a water retaining wall 201 is distributed on the outer periphery of the shed body structure 2, the lower part of the water retaining wall 201 is buried below the planting ground of the greenhouse, and the upper part of the water retaining wall 201 is located on the Above the planting ground, the drip irrigation pipe 1 is buried below the planting ground of the greenhouse and is arranged below the lower part of the water blocking board 201. Specifically, by arranging the water baffle 201 on the outside of the shed structure 2, it is possible to avoid the rainwater outside the shed structure 2 from seeping into the soil surface layer in the shed structure 2 in order to maintain the shed to the maximum extent The surface layer of soil in structure 2 remains dry.
针对上述大棚的具体结构形式，在实际使用过程中，则可以根据栽种的植物品种得知该植物不同季节时间段内对供水量的需求，从而实现不同时期定量的供水。具体的控制方法为：滴灌管在种植地面以下对种植物的根系定量供水；在雨天环境下，第一棚膜和第二棚膜处于展开状态，以对大棚的顶部和侧部进行遮挡防雨；在非雨天环境下，第一棚膜和第二棚膜处于收卷状态。具体的，大棚中栽种的植物主要通过地面下方的滴灌管完成灌溉，而为了避免雨天对精确灌溉量的影响，则在雨天环境下，通过将大棚顶部和侧部的棚膜全部展开，以通过棚膜阻挡雨水进入到大棚中，这样，便可以有效的提高植物供水的精确性。而在非雨天环境下，则将收卷第一棚膜和第二棚膜，以使得植物能够直接与外界接触获得光照，以最大程度的实现露天种植的效果，从而可以使得植物获得良好的种植品质。Regarding the specific structure of the above-mentioned greenhouse, in actual use, the plant's demand for water supply in different seasons can be known according to the plant species planted, so as to achieve quantitative water supply in different periods. The specific control method is: the drip irrigation pipe provides quantitative water supply to the root system of the plant below the planting ground; in the rainy environment, the first shed film and the second shed film are in an expanded state to shield the top and sides of the greenhouse from rain ; In a non-rainy environment, the first shed film and the second shed film are in a rewinding state. Specifically, the plants planted in the greenhouse are mainly irrigated through drip irrigation pipes below the ground, and in order to avoid the influence of rain on the precise irrigation amount, under the rainy environment, all the membranes on the top and side of the greenhouse are unfolded to pass The shed membrane prevents rainwater from entering the greenhouse, so that the accuracy of water supply by plants can be effectively improved. In a non-rainy environment, the first shed film and the second shed film will be rolled up, so that the plants can directly contact the outside world to obtain light, so as to maximize the effect of open planting, so that the plants can be planted well quality.
其中，为了针对特定的植物进行精确的灌溉以获得优良的作物。则可以根据该种植物在生长周期内，不同阶段的需水量不同，指定特定的供水计划。即根据大棚中栽种的植物品种，获取该植物在生长周期内的供水曲线，根据该植物对应的供水曲线控制滴灌管对植物的根系定量供水。具体的，以种植葡萄为例，特定品种的葡萄可以获知其优选的供水方案（例如：82年波尔多地区种植的葡萄的品质优良，则可以根据该年度该地区的降水量来获得葡萄不同时间段内对应的供水曲线），获得该葡萄的供水曲线后，则在日常灌溉过程中，依照该供水曲线对葡萄的根系进行定期定量的灌溉，从而获得最佳的植物生长周期。Among them, in order to accurately irrigate specific plants to obtain excellent crops. You can specify a specific water supply plan according to the different water requirements of the plant in different stages of the growth cycle. That is, according to the plant species planted in the greenhouse, the water supply curve of the plant in the growth cycle is obtained, and the drip irrigation pipe is used to control the quantitative water supply to the root system of the plant according to the water supply curve corresponding to the plant. Specifically, taking grape cultivation as an example, certain varieties of grapes can be informed of their preferred water supply scheme (for example: the grapes grown in Bordeaux in 1982 are of good quality, and different periods of time can be obtained according to the precipitation in the area in the year Corresponding water supply curve), after obtaining the water supply curve of the grape, in the daily irrigation process, according to the water supply curve, the root system of the grape is regularly and quantitatively irrigated to obtain the best plant growth cycle.
基于上述技术方案，可选的，如图14-图18所示，大棚通常搭建在不同的区域1000，不同区域1000之间则存在降雨量分配不均的情况。而为了实现各个区域1000之间人工调配水量，则同一区域1000中配置有主管网3，同一区域1000中的分布在不同大棚周围的蓄水池31分别与主管网3连接，而不同区域1000之间的主管网3相互连接。这样，各个区域1000中的主管网3和蓄水池31共同形成区域化雨水再利用调配***。蓄水池31中设置有潜水泵311和液位检测器312，各个所述潜水泵311分别与主管网3连接，主管网3和蓄水池31之间还设置有回水管313，所述回水管313上设置有第一电控阀（未标记），相邻两个区域1000中的所述主管网3连接在一起；区域化雨水再利用调配***还包括主控制器（未图示）和多个区域控制器（未图示），所述区域控制器用于与所述潜水泵311、所述液位检测器312和所述第一电控阀信号连接，所述区域控制器与所述主控制器信号连接。Based on the above technical solution, optionally, as shown in FIGS. 14-18, the shed is usually built in different areas 1000, and uneven rainfall distribution may exist between different areas 1000. In order to realize the artificial water allocation between the regions 1000, the main network 3 is arranged in the same region 1000, and the reservoirs 31 distributed around different greenhouses in the same region 1000 are respectively connected to the main network 3, while the different regions 1000 The inter-administrative network 3 is connected to each other. In this way, the main grid 3 and the reservoir 31 in each area 1000 together form a regionalized rainwater reuse and distribution system. The reservoir 31 is provided with a submersible pump 311 and a liquid level detector 312, and each of the submersible pumps 311 is respectively connected to the main grid 3, and a return water pipe 313 is further provided between the main grid 3 and the reservoir 31. The water pipe 313 is provided with a first electric control valve (not marked), and the main grid 3 in two adjacent areas 1000 are connected together; the regionalized rainwater reuse and distribution system also includes a main controller (not shown) and A plurality of area controllers (not shown), the area controllers are used for signal connection with the submersible pump 311, the liquid level detector 312 and the first electronically controlled valve, the area controllers are connected with the Main controller signal connection.
具体而言，在不同区域1000内，年降雨量各不相同，以单个区域为乡镇或城区为例进行说明，同一个区域范围内存在农作物种植区和城市绿化区域，日常均需要供水进行灌溉，则对应的在地下配置有蓄水池31，在降雨环境下，通过雨水收集***收集降雨并输送到蓄水池31中进行存储，这样，便可以有效的收集雨水，以避免雨天过多的雨水流淌至江河而无法再利用，而当需要用水时，则可以利用蓄水池31中的雨水进行灌溉。更重要的是，针对不同区域降雨分布不均的情况下，则可以根据液位检测器312检测蓄水池31的水位，在水位较高的情况下，通过潜水泵311将高水位的蓄水池31中的水输送到主管网3以用于供给其他低水位的蓄水池31；同时，针对跨区域雨水分布不均的情况下，不同区域之间通过主管网3进行雨水的调配。Specifically, in different regions 1000, the annual rainfall is different. Taking a single area as a town or an urban area for example, there are crop planting areas and urban greening areas within the same area, and daily water supply is needed for irrigation. Correspondingly, the reservoir 31 is arranged underground. In the rainy environment, the rainwater collection system collects the rainwater and sends it to the reservoir 31 for storage, so that the rainwater can be effectively collected to avoid excessive rainwater on rainy days. It flows to the river and cannot be reused, and when water is needed, the rainwater in the reservoir 31 can be used for irrigation. More importantly, in the case of uneven rainfall distribution in different areas, the water level of the reservoir 31 can be detected according to the liquid level detector 312, and when the water level is high, the submersible pump 311 can store the high water level The water in the pond 31 is sent to the main grid 3 for supplying other low-level water storage tanks 31; at the same time, in the case of uneven distribution of rainwater across regions, rainwater is distributed through the main grid 3 between different regions.
