Description

Technical Field

[0001] The utility model relates to the technical field of crop planting, in particular to a vegetable planting greenhouse capable of recycling rainwater. Background Art

[0002] Greenhouses are widely used in agricultural planting and play a role in heat preservation and heating control. The composition of the greenhouse is a skeleton made of bamboo poles, cement poles, light steel pipes or pipes, etc., which are made into columns, pull rods, arch rods and pressure rods, and covered with plastic film to become an arched material shed.

[0003] There are certain problems in the use of existing planting greenhouses. For example, when the plants planted in the greenhouse need to be watered, groundwater and other water resources are still needed, but the rain and snow in rainy and snowy weather are blocked outside by plastic film and cannot be used to irrigate the crops in the greenhouse, resulting in a waste of water resources. Therefore, greenhouse rainwater collection is an effective way to save water resources and effectively utilize natural resources. Therefore, it is necessary to set up a vegetable planting greenhouse that can collect and purify rainwater and recycle rainwater, so that it can collect rainwater and purify it for irrigation and fertilization of crops in the greenhouse. Utility Model Content

[0004] In view of the problems and shortcomings in the prior art, the utility model provides a vegetable planting greenhouse capable of recycling rainwater.

[0007] The rainwater collection device includes:

[0008] The filter tank and the water storage tank are arranged on the left and right, and the two are separated by a first partition in the middle;

[0009] A first filtering device is provided at the top opening of the filtering pool, for allowing rainwater to enter the filtering pool and be filtered;

[0010] A second filter device is provided at the bottom of the first partition, the second filter device is connected to a water pump through a pipeline, the outlet of the water pump is connected to the water reservoir, and the water pump is arranged in a first equipment room located on one side of the water reservoir;

[0011] A cover plate is arranged on the top of the water storage tank, and a disinfection device is arranged on the cover plate. The disinfection device comprises a disinfection box arranged on the top of the cover plate and a disinfection nozzle connected with the disinfection box and arranged at the bottom of the cover plate.

[0012] Specifically, the filter pool and the water storage tank are arranged under the ground and can be constructed of a concrete structure or a steel plate with an anti-corrosion layer. The filter pool is used to collect and filter rainwater, and the water storage tank is used to disinfect and store rainwater for irrigation or fertilization. The first filter device uses a filter screen composed of three layers of filter plates to filter sand and rotten leaves. The second filter device is provided with a filter element composed of sand, limestone, activated carbon and gauze to remove acidic substances and large particles.

[0013] On rainy days, rainwater flows down along the top arch of the greenhouse body and enters the filter pool through both sides of the greenhouse body. The first filter device at the top of the filter pool filters out larger impurities such as sand and gravel particles and plant rotten leaves in the rainwater. After that, the rainwater entering the filter pool enters the reservoir through the second filter device set on the first partition under the action of the water pump. The second filter device is equipped with a filter element inside to filter acidic substances and small particles in the rainwater. After the filtered rainwater enters the reservoir, the disinfection device is turned on, and the medicine in the disinfection box is evenly sprayed into the reservoir through the nozzle to remove harmful substances in the rainwater, such as sulfur, phosphorus, heavy metals, exhaust gas, etc. The disinfected wastewater enters the irrigation system of the greenhouse through the water pump for irrigation or fertilization of crops in the greenhouse. Specifically, the disinfection device is controlled by the control unit and the electromagnetic generator.

[0014] In a specific embodiment, the disinfection nozzle extends along the length direction of the water reservoir, and multiple nozzles are arranged at intervals along the width direction of the water reservoir. Multiple nozzles are evenly spaced on the disinfection nozzle along the length direction. The disinfection nozzle and nozzles are evenly arranged on the top of the water reservoir and cover the water surface, so as to evenly and fully spray the disinfectant inside the water reservoir, so that the disinfectant is fully mixed with rainwater, and the disinfection effect and efficiency are improved.

[0015] A vegetable planting greenhouse capable of recycling rainwater also includes a stirring device arranged in a water reservoir. The stirring device includes a motor and a stirrer, the stirrer is rotatably connected to the side wall of the water reservoir and driven by the motor. The motor is fixedly arranged in a second equipment room outside the water reservoir.

[0016] By setting up the stirring device, the rainwater in the reservoir can be stirred while the disinfectant is sprayed by the disinfection device, thereby improving the mixing efficiency of the disinfectant and rainwater, thereby improving the reaction rate and purification effect.

[0017] In a specific embodiment, a liquid level meter is also provided in the water reservoir to measure the liquid level in the water reservoir, thereby obtaining the water storage amount, which is convenient for further controlling irrigation.

[0018] The greenhouse body includes a frame and a film covering the outside. The frame is a metal frame with an arched top and a support member tilted outward at the bottom. The outside of the frame is covered with a film, and rainwater collection devices are located on both sides of the bottom of the film and underground, so that rainwater sliding down the large film can enter the rainwater collection device.

[0019] The beneficial effects of the utility model are:

[0020] Rainwater in the greenhouse area is collected by a rainwater collection device and double filtered through a filter pool to remove large particles and acidic substances. It is then disinfected in a reservoir to remove harmful chemical elements, heavy metals, waste gas and other substances. Finally, the purified water is used for irrigation and fertilization of crops in the greenhouse through the greenhouse irrigation system, reducing water waste and improving the utilization rate of rainwater.
