Description

Technical Field

[0001] This utility model relates to the field of glass greenhouses, and more particularly to the field of greenhouse roof cleaning, specifically referring to a device for cleaning the roofs of multi-span glass greenhouses. Background Technology

[0002] by Figure 1 The textured, multi-span glass greenhouse shown is currently the most widely used and advanced greenhouse structure imported from abroad. It mainly consists of a light steel frame, a roof, and highly transparent glass sides, presented in a multi-span configuration, covering an area of ​​over 10 hectares. Sunlight passes through the glass on the top and sides of the greenhouse, significantly impacting the growth of crops inside.

[0003] Studies have shown that dust pollution in greenhouses can reduce light transmittance by 20-30% under normal circumstances. Severe dust pollution significantly reduces light intensity inside the greenhouse, affecting plant photosynthesis and growth, leading to reduced crop yields. Therefore, maintaining a clean greenhouse roof and improving light transmittance is crucial. Currently, cleaning is mostly done manually, which is inefficient and poses safety hazards. Greenhouse drainage channels easily accumulate wastewater, and dirt tends to build up at the bottom of windows. Utility Model Content

[0082] The cleaning truck can automatically travel back and forth to clean the glass ridge of the multi-span glass greenhouse, and can clean drainage channels, glass windows and the bottom of windows, which are places where dirt easily accumulates.

[0083] The cleaning truck has an independent walking device, an independent hydraulic drum, and a cleaning device.

[0084] The shading spraying device can automatically travel back and forth to spray shading paint on the three ridges of the glass greenhouse at the same time.

[0085] The mobile platform can automatically move the cleaning vehicle along the track from one ridge of the multi-span glass greenhouse to the next, and can be adjusted according to the different ridge heights of the multi-span glass greenhouses.

[0086] The platform on the mobile platform uses a grid plate instead of a bending plate, which simplifies processing and facilitates replacement. The tilting assembly 2-3 on the mobile platform consists of two lifting parts and a clamping block, making it easy to replace if damaged.

[0087] The lower guide rail 2-5.2 of the mobile platform is fixed to the wall, which eliminates the need for a hardened surface compared to fixing it to the ground.

[0088] The greenhouse roof cleaning machine is a machine that cleans roofs using rotating brushes and water. The machine has column brushes 1-4.1, disc brushes 1-4.3, and drain gutter side brushes 1-4.2, which can automatically clean greenhouse roof glass, window bases, and drain gutters. The machine has two reels, one for the power cord and the other for the water hose. The machine is constructed with an aluminum frame to meet the light load-bearing requirements of greenhouse roofs. The wheels are motor-driven, while the rollers and reels are hydraulically driven. The control cabinet is equipped with safety devices, control, and communication functions. Sensors are installed in front of the four wheels to detect forward and backward movement. Additionally, sensors are installed on the roof ventilation windows to prevent collisions caused by open ventilation windows during cleaning.

[0089] The mobile platform moves the cleaning machine along tracks from one ridge to the next. These tracks are installed along one side of the greenhouse, covering its entire length. The platform offers both manual and automatic operation options. Two connecting plates link to the gutters; these plates can only be flipped up for the cleaning machine to use after the mobile platform is aligned with each ridge to be cleaned. Safety devices, control systems, and communication functions are all housed in the control cabinet.

[0090] Water supply unit (pump): Provides clean water for the roof cleaning machine. It consists of a pump, water tank, and piping. This unit is placed on a mobile platform, 6-7 meters above the ground. The inlet water pressure is not less than 1 bar, and the flow rate is not less than 50 L / min. The unit is centrally controlled in the platform control cabinet.

[0091] Shading Spraying Device: When sunlight intensity is too high, the shading spraying device can evenly spray shading paint onto the glass roof to block sunlight. The spraying device consists of a spraying arm and a powder pump truck. When deployed, the spraying arm can simultaneously cover three roof ridges. The powder pump truck is placed on the ground and connected to the spraying arm via a delivery pipeline. The pump inside the powder pump truck delivers the powder medium through the pipeline to the spraying arm, providing a stable powder supply. The control cabinet is mounted on the powder pump truck, which communicates wirelessly with the roof cleaning machine. This greenhouse roof cleaning device can efficiently and automatically clean greenhouse glass, ensuring the light transmittance of the greenhouse roof.

[0092] The working process of this greenhouse roof cleaning device is as follows:

[0093] During roof cleaning, the mobile platform 2 carrying the roof cleaning machine 1 moves to the front of the first ridge via the positioning mechanism 2-4. After ensuring the movement path of the roof cleaning machine 1 is aligned with the gutter, the mobile platform 2 lowers the tilting mechanism 2-3, and the roof cleaning machine 1 and water pump 3 are turned on. The roof cleaning machine 1 moves from the mobile platform 2 onto the roof and begins cleaning until it reaches the end of the roof. During the cleaning process, if the sensor 1-3.2 of the roof ventilation window of the roof cleaning machine 1 detects that the ventilation window is not closed, the roof cleaning machine 1 immediately stops moving forward and cleaning. After detection by sensor 1-3.1, the roof cleaning machine 1 returns from the end of the roof to clean until it returns to the mobile platform 2, completing the cleaning of the first ridge. The roof cleaning machine 1 and water pump 3 are turned off, the mobile platform 2 retracts the tilting mechanism 2-3, and the mobile platform 2 carrying the multi-span glass greenhouse roof cleaning machine 1 moves to the next ridge to repeat the previous cleaning steps; when the set program cycle is completed, the multi-span glass greenhouse roof cleaning machine 1 will automatically stop.

[0094] During roof shading spraying, the mobile platform 2 carrying the roof cleaning machine 1 moves to the front of the second ridge via the positioning mechanism 2-4, ensuring that the travel path of the roof cleaning machine 1 is aligned with the gutter. The appropriate paint ratio is prepared in the powder pump truck 4-2, ensuring the paint is evenly mixed and does not settle. The water inlet pipe of the roof cleaning machine 1 is switched to the liquid supply pipe of the pump truck 4-2. The tilting mechanism 2-3 is lowered from the mobile platform 2, and the two spraying arms 4-1 are manually opened to cover the left, center, and right ridges. The water inlet pipe under the cleaning machine's motor compartment is switched to the powder spraying pipe. After the roof cleaning machine 1 moves from the mobile platform 2 onto the roof, the powder pump truck 4-2 is started to begin spraying powder until the end of the roof. During spraying, if the sensor 1-3.2 of the roof ventilation window of the roof cleaning machine 1 detects that the ventilation window is not closed, the roof cleaning machine 1 immediately stops moving forward and spraying. After the sensor 1.2 detects the end, the roof cleaning machine 1 returns from the end of the roof to spray powder until it reaches the beginning of the roof. Then, it stops spraying powder and returns to the moving platform 2. The moving platform 2 retracts the flipping mechanism 2-3 and moves the moving platform 2 with the roof cleaning machine 1 to the next ridge. The previous steps are repeated. When the set program cycle is completed, the multi-span glass greenhouse roof cleaning machine 1 will stop automatically.

[0095] During roof shading spraying and cleaning, the mobile platform 2 carrying the roof cleaning machine 1 moves to the front of the first ridge via the positioning mechanism 2-4, ensuring that the travel path of the roof cleaning machine 1 is aligned with the gutter. A suitable cleaning solution is prepared in the powder pump truck 4-2. The water inlet pipe of the roof cleaning machine 1 is connected to the liquid supply pipe of the pump truck 4-2. The mobile platform 2 lowers the tilting mechanism 2-3. The roof cleaning machine 1 and the powder pump truck 4-2 are turned on. The roof cleaning machine 1 moves from the mobile platform 2 onto the roof and begins cleaning until it reaches the end of the roof. During the cleaning process, if the sensor 1-3.2 of the roof ventilation window of the roof cleaning machine 1 detects that the ventilation window is not closed, the roof cleaning machine 1 immediately stops moving forward and cleaning. The roof cleaning machine 1 returns from the end of the roof to clean until it returns to the mobile platform 2. The roof cleaning machine 1 and the powder pump truck 4-2 are turned off. The mobile platform 2 retracts the tilting mechanism 2-3. The mobile platform 2 carrying the multi-span glass greenhouse roof cleaning machine 1 moves to the next ridge and repeats the previous steps. When the set program cycle is completed, the multi-span glass greenhouse roof cleaning machine will automatically stop.

[0096] This utility model equipment can achieve efficient and automatic cleaning of greenhouse glass. It has a high degree of automation, is easy to operate, has good cleaning effect, and high work efficiency.

[0097] The greenhouse roof cleaning device described in this invention is placed on the top of a textured multi-span glass greenhouse. The cleaning machine's four wheels move back and forth along the greenhouse's gutters. A hydraulic system, connected via pipelines, cleans the greenhouse roof. The four wheels are powered by a bidirectional output from a geared motor, automatically controlled by a PLC. This allows the cleaning machine to rotate in the opposite direction when returning to the greenhouse for cleaning. The main frame is made of lightweight, high-density aluminum alloy. This invention features a simple design, enabling efficient cleaning of dusty greenhouse surfaces and restoring light transmittance. The mobile platform automatically moves the cleaning cart along tracks from one ridge of the greenhouse glass to the next, adjusting according to ridge height. The shading spraying device automatically sprays shading paint onto all three ridges of the greenhouse glass simultaneously. This invention is suitable for textured multi-span glass greenhouses, extending their lifespan, mitigating the decrease in light transmittance due to dust accumulation on the glass over time, and improving economic efficiency.
