Description

Technical Field

[0001] This utility model belongs to the field of glass greenhouse technology, specifically a drainage device for glass greenhouses. Background Technology

[0002] A glass greenhouse is a type of greenhouse that uses glass as its primary light-transmitting covering material. It is one of the longest-lasting forms of cultivation facilities, suitable for various regions and climates. Existing glass greenhouses are equipped with specialized rainwater drainage systems on their roofs to effectively manage rainwater runoff.

[0003] A search revealed a drainage structure for a glass greenhouse, as disclosed in announcement number CN221920045U. Its main features include: a drainage board, drainage trough, drainage pipe, and filter box located on the drainage surface of the glass greenhouse; a rotating unit between the drainage trough and the glass greenhouse, used to drive the drainage trough to tilt back and forth; the rotating unit includes a drive motor, support components, and connectors; and a filter unit between the filter box and the drainage pipe, used to collect debris from inside the drainage pipe; the filter unit includes a filter screen and filter elements.

[0004] In actual use, the applicant found that the aforementioned drainage device for glass greenhouses uses natural water flow to flush garbage on the filter screen into the first connecting pipe and guide the garbage into the collection box. However, in actual use, when rainfall is low, rainwater alone cannot completely flush away the garbage on the filter screen, and the garbage easily clogs the first connecting pipe, thus affecting the centralized collection of garbage. At the same time, when cleaning the collection box, the top cover of the collection box must be opened, and then the garbage inside the collection box must be taken out, which is very troublesome and inconvenient for later maintenance. In order to solve the above-mentioned problems, a drainage device for glass greenhouses is provided. Utility Model Content

Two locking screws are rotatably connected to the front side wall of the collection box. Two U-shaped locking grooves corresponding to the positions of the locking screws are opened on one side of the sealing door. The locking screws are engaged in the U-shaped locking grooves. A dovetail cap is threaded onto the locking screw.

[0008] In a preferred embodiment, the drainage channel is inclined, and the filter channel is located at the lowest point of the drainage channel.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The following will combine Figures 1-3 A detailed description of a drainage device for a glass greenhouse according to an embodiment of the present invention will be provided. Example

[0022] This utility model provides a drainage device for a glass greenhouse, see reference. Figures 1 to 3As shown, the structure includes a glass greenhouse 1, a drainage trough 2 fixedly installed on the drainage surface of the glass greenhouse 1, a filter trough 3 fixedly connected to one side of the drainage trough 2, the filter trough 3 fixedly installed on the glass greenhouse 1, a drainage pipe 4 fixedly connected to the bottom of the filter trough 3, the drainage pipe 4 fixedly installed on the glass greenhouse 1, and a U-shaped filter plate 5 fixedly installed on the inner wall of the filter trough 3. In this structure, rainwater from the slope of the glass greenhouse 1 will fall into the drainage trough 2, and then the drainage trough 2 will guide the rainwater into the filter trough 3. At this time, the U-shaped filter plate 5 is used to filter the impurities in the rainwater, and the filtered rainwater will be discharged into the underground rainwater pipe through the drainage pipe 4.

[0023] refer to Figures 1 to 3 As shown, a rotating rod 6 is rotatably mounted on a filter trough 3 inside the U-shaped filter plate 5. A motor 7 is fixedly connected to the outer wall of the filter trough 3. The motor 7 is connected to the rotating rod 6 through an output shaft. A spiral conveying blade 8 is fixedly connected to the outer wall of the rotating rod 6. A discharge pipe 10 is fixedly connected to one side of the filter trough 3. Both the rotating rod 6 and the spiral conveying blade 8 extend into the discharge pipe 10. A collection box 11 is fixedly connected to the discharge side of the discharge pipe 10. The collection box 11 is fixedly mounted on the glass greenhouse 1. This structure drives the conveying spiral blade 8 on the rotating rod 6 to rotate through the motor 7. The conveying spiral blade 8 can transport the garbage on the U-shaped filter plate 5 into the discharge pipe 10 and finally into the collection box 11, thereby collecting and treating the debris in the rainwater. The entire structure can use the rotating conveying spiral blade 8 to forcefully transport and clean the debris on the U-shaped filter plate 5, thereby avoiding the accumulation of debris on the U-shaped filter plate 5. At the same time, the conveying spiral blade 8 can forcefully transport the debris entering the discharge pipe 10, thereby avoiding the garbage from clogging the discharge pipe 10 and ensuring stable discharge.

[0024] refer to Figures 1 to 3 As shown, a support plate 12 is fixedly connected to the lower part of the inner cavity of the collection box 11. A collection basket 13 is placed on the support plate 12. A cleaning port 15 is opened on the front side of the collection box 11. A sealing door 16 is hinged to the front side of the collection box 11. Two locking screws 17 are rotatably connected to the front side wall of the collection box 11. Two U-shaped locking grooves 18 corresponding to the positions of the locking screws 17 are opened on one side of the sealing door 16. The locking screws 17 are inserted into the U-shaped locking grooves 18. A dovetail cap 19 is threaded onto the locking screws 17. In this structure, after the debris in the rainwater enters the collection box 11, it will fall into the collection basket 13 on the support plate 12. When cleaning the debris later, simply loosen the dovetail cap 19, then deflect the locking screws 17, and then the sealing door 16 can be opened to remove the collection basket 13 from the collection box 11, thus facilitating the maintenance of the collection box 11.

[0025] refer to Figures 1 to 3 As shown, a transparent observation window 24 is installed on the sealed door 16. This structure utilizes the transparent observation window 24 to observe the collection situation inside the collection box 11.

[0026] refer to Figures 1 to 3 As shown, filter screens 14 are fixedly connected to both sides of the top surface of the tray 12. The left and right sides and top of the filter screens 14 are fixedly installed on the inner wall of the collection box 11. A water guide pipe 23 is fixedly installed at the bottom of the collection box 11. The outlet end of the water guide pipe 23 is connected to the drain pipe 4. In this structure, the collection basket 13 structure facilitates the passage of rainwater. After the rainwater passes through the filter screen 14, it will fall into the water guide pipe 23 at the bottom of the collection box 11, thereby guiding the rainwater into the drain pipe 4 and thus draining the rainwater that has entered the collection box 11.

[0027] Since the height of the filter screen 14 is higher than that of the collection basket 13, excess rainwater can be discharged from the top of the filter screen 14, thereby preventing the collection box 11 from becoming clogged.

[0028] refer to Figures 1 to 3 As shown, the drainage channel 2 is inclined, and the filter channel 3 is located at the lowest point of the drainage channel 2. This structure facilitates the introduction of rainwater into the drainage channel 2.

[0029] refer to Figures 1 to 3 As shown, the spiral conveyor blade 8 has uniformly distributed water-permeable holes 20. In this structure, the water-permeable holes 20 allow rainwater to pass through the spiral conveyor blade 8, thereby preventing the spiral conveyor blade 8 from blocking the rainwater from falling. At the same time, the spiral conveyor blade 8 reduces the amount of rainwater transported into the collection box 11.

[0030] refer to Figures 1 to 3 As shown, the inner side of the sealing door 16 has a square protrusion 21 that matches the cleaning port 15. A sealing strip 22 is fixedly installed on the sealing door 16 around the square protrusion 21. This structure uses the square protrusion 21 in conjunction with the sealing strip 22 to ensure the sealing of the sealing door 16 after it is closed.

[0031] The implementation principle of a drainage device for a glass greenhouse according to an embodiment of this application is as follows: When in use, rainwater on the slope of the glass greenhouse 1 will fall into the drainage trough 2, and then the drainage trough 2 will guide the rainwater into the filter trough 3. At this time, the U-shaped filter plate 5 is used to filter the impurities in the rainwater, and the filtered rainwater will be discharged into the underground rainwater pipe through the drainage pipe 4.

[0032] During use, the motor 7 drives the conveying spiral blade 8 on the rotating rod 6 to rotate. The conveying spiral blade 8 can transport the garbage on the U-shaped filter plate 5 to the discharge pipe 10 and finally to the collection box 11. Then it falls into the collection basket 13 on the support plate 12. At this time, the structure of the collection basket 13 facilitates the passage of rainwater. After the rainwater passes through the filter screen 14, it falls into the water guide pipe 23 at the bottom of the collection box 11, thereby guiding the rainwater into the drain pipe 4 and thus draining the rainwater that has entered the collection box 11.

[0033] In daily use, personnel can observe the collection status of the internal collection basket 13 through the transparent observation window 24 on the sealed door 16. When the cleaning standard is reached, it is cleaned. When cleaning debris later, simply loosen the dovetail cap 19, then deflect the locking screw 17, and then open the sealed door 16 to remove the collection basket 13 from the collection box 11, thus facilitating the maintenance of the collection box 11.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
