Description

Technical Field

[0001] This utility model belongs to the technical field of mushroom cultivation equipment, and in particular relates to a solar-assisted intelligent ventilation device for mushroom houses. Background Technology

[0002] Mushroom houses are specialized facilities for the artificial cultivation of edible fungi. They create optimal conditions for mushroom growth by precisely controlling environmental parameters such as temperature, humidity, light, ventilation, and carbon dioxide concentration. Their structures typically use thermal insulation materials and are equipped with intelligent environmental control systems, such as humidifiers, ventilation fans, and temperature control devices, to simulate natural ecosystems and optimize the growth cycle.

[0003] Ventilation systems in mushroom cultivation houses are core equipment for ensuring the healthy growth of mushrooms, maintaining a stable environment through precise airflow control. Traditional systems use upper and lower windows and exhaust ducts, relying on natural convection to expel carbon dioxide. Existing solar-assisted intelligent ventilation systems for mushroom cultivation houses use solar panels to power the exhaust fan. During operation, the exhaust fan expels air from the mushroom cultivation house. Since the air inside contains impurities such as dust, pollen, and insects, filters are used to purify the airflow. However, over time, these filters become clogged, and the impurities separated from the filters cannot be removed in time, resulting in ineffective cleaning. To address these issues, designing a solar-assisted intelligent ventilation system for mushroom cultivation houses is essential. Utility Model Content

[0004] This invention provides a solar-assisted intelligent ventilation device for mushroom houses to solve the above-mentioned problems in the prior art.

[0005] This utility model is implemented as follows: a solar-assisted intelligent ventilation device for mushroom houses, comprising: The pipe has an exhaust fan at one end, which is connected to the outer wall of the mushroom house by multiple screws. The exhaust fan's air inlet pipe is connected to the pipe, and its exhaust pipe is connected to the outside. The lower end of the pipe is open, and a branch pipe is connected and fixedly installed on the side of the lower end of the pipe. The branch pipe is connected to the internal space of the mushroom house. A sealing plug is provided at the lower port of the pipe, which is threaded into the lower port of the pipe and seals it. A filter screen is provided inside the pipe and is connected to the pipe by screws. Multiple conical protrusions are fixedly installed on the top of the filter screen in a circumferential array. An annular ring is provided inside the pipe, and multiple impact components are arranged in a circumferential array on the annular ring. The impact components work with the protrusions to impact the filter screen.

[0006] Preferably, the exhaust fan is powered by an external solar panel, and the exhaust fan is electrically connected to an external controller, which controls the exhaust fan to work intermittently.

[0007] Preferably, the branch pipe port is configured in a flared, horn-shaped configuration.

[0008] Preferably, the impact assembly includes a guide rod that passes through the annular ring and is slidably mounted on the annular ring. An impact head is fixedly mounted on the bottom of the guide rod. A spring is sleeved on the guide rod, and the upper and lower ends of the spring are fixedly connected to the impact head and the annular ring, respectively. The bottom end of the impact head is dome-shaped.

[0009] Preferably, a limiting piece is fixedly installed on the top of the guide rod.

[0010] Preferably, the pipe is provided with a driving mechanism, which is connected to the annular ring and is used to drive the annular ring to rotate.

[0011] Preferably, the drive mechanism includes an internal gear ring, which is fixedly installed inside the annular ring. A servo motor is fixedly installed inside the pipe, and a drive wheel is fixedly installed at the output shaft end of the servo motor. The drive wheel meshes with the internal gear ring.

[0012] Preferably, the servo motor is powered by an external solar panel, the servo motor is electrically connected to an external controller, the external controller controls the servo motor to work intermittently, and a flow detector is installed inside the pipeline.

[0013] Compared with related technologies, the solar-assisted intelligent ventilation device for mushroom houses provided by this utility model has the following beneficial effects: A servo motor drives a ring to rotate, causing the impact assembly to move along a circular trajectory, periodically striking the protrusions at different locations. When the impact head rotates with the ring to directly above a protrusion, it is compressed by the protrusion, causing both the impact head and guide rod to move upwards and the spring to contract. After the impact head separates from the protrusion, the spring drives it to slide down the guide rod, impacting the filter screen and causing it to vibrate. This cycle repeats, subjecting the filter screen to multiple impacts. The impact force loosens or dislodges impurities adhering to the filter screen surface, preventing clogging. The dislodged impurities fall to the lower end of the pipe and seal through a plug, thus concentrating the impurities on the plug. After cleaning, the impurities can be promptly separated from the filter screen.

[0014] The exhaust fan is powered by an external solar panel and is electrically connected to an external controller. The controller controls the exhaust fan to operate intermittently, thus intermittently accelerating the ventilation efficiency of the mushroom house. This intermittent operation achieves ventilation while avoiding prolonged, unproductive operation. The exhaust fan and servo motor are primarily powered by the solar panel, with a battery serving as a backup power source to ensure the device can still operate when sunlight is insufficient.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] A preferred embodiment of the solar-assisted intelligent ventilation device for mushroom houses provided by this utility model is, for example... Figures 1 to 5 As shown: A solar-assisted intelligent ventilation device for mushroom houses includes: Pipe 1 has an exhaust fan 2 at one end, which is connected to the outer wall of the mushroom house by multiple screws. The air inlet pipe of the exhaust fan 2 is connected to pipe 1, and the exhaust pipe of the exhaust fan 2 is connected to the outside. Pipe 1 has an opening at its lower end, and a branch pipe 3 is connected to and fixedly installed on the side of the lower end of pipe 1. The branch pipe 3 is connected to the internal space of the mushroom house. A sealing plug 4 is provided at the lower port of pipe 1, which is threaded into the lower port of pipe 1 and seals the lower port of pipe 1. A filter screen 5 is provided inside pipe 1 and is connected to pipe 1 by screws. Multiple conical protrusions 8 are fixedly installed on the top of the filter screen 5 in a circumferential array. A ring 6 is provided inside pipe 1, and multiple impact components 7 are arranged in a circumferential array on the ring 6. The impact components 7 work with the protrusions 8 to impact the filter screen 5. The port of the branch pipe 3 is flared outward.

[0020] The impact assembly 7 includes a guide rod 9, which passes through an annular ring 6 and slides up and down on the annular ring 6. An impact head 10 is fixedly installed at the bottom of the guide rod 9. A spring 11 is sleeved on the guide rod 9, and the upper and lower ends of the spring 11 are fixedly connected to the impact head 10 and the annular ring 6, respectively. The bottom end of the impact head 10 is dome-shaped. A limit plate 12 is fixedly installed at the top of the guide rod 9.

[0021] A drive mechanism is provided inside the pipe 1. The drive mechanism is connected to the annular ring 6 and is used to drive the annular ring 6 to rotate. The drive mechanism includes an internal gear ring 13, which is fixedly installed inside the annular ring 6. A servo motor 14 is fixedly installed inside the pipe 1. A drive wheel 15 is fixedly installed at the output shaft end of the servo motor 14. The drive wheel 15 meshes with the internal gear ring 13.

[0022] The exhaust fan 2 draws air from the mushroom house through pipe 1 and branch pipe 3, creating a negative pressure airflow. The flared design of branch pipe 3 expands the air intake range and improves air collection efficiency.

[0023] Airflow carrying dust, pollen, insect remains, and other impurities enters pipe 1 and is intercepted by filter screen 5. Filter screen 5 is fixed inside pipe 1 with screws, forming the first purification barrier. After long-term operation, impurities accumulate on the surface of filter screen 5, leading to decreased air permeability and reduced ventilation efficiency. Traditional devices require manual disassembly and cleaning, which is cumbersome and affects the stability of the mushroom house environment. Guide rod 9 passes through the annular ring 6 and can slide up and down, with a limiting plate 12 at the top to prevent it from falling out.

[0024] The servo motor 14 drives the drive wheel 15 to rotate via its output shaft. When the servo motor 14 rotates, it drives the internal gear ring 13 to rotate via the drive wheel 15. The internal gear ring 13 and the annular ring 6 rotate synchronously. The annular ring 6 drives the impact assembly 7 to move along a circular trajectory, causing the impact head 10 to periodically impact the protrusions 8 at different positions.

[0025] When the impact head 10 rotates with the annular ring 6 to directly above the protrusion 8, the impact head 10 is squeezed by the protrusion 8. Both the impact head 10 and the guide rod 9 move upward, and the spring 11 contracts. After the impact head 10 separates from the protrusion 8, the spring 11 drives the impact head 10 to slide down along the guide rod 9. The impact head 10 impacts the filter screen 5, causing the filter screen 5 to vibrate. This cycle repeats, allowing the filter screen 5 to be impacted multiple times. The impact force loosens or removes impurities attached to the surface of the filter screen 5, preventing the filter screen 5 from being clogged by impurities.

[0026] After the impurities fall off, they can fall to the lower end of pipe 1 and be sealed by the sealing plug 4, so that the impurities are concentrated on the sealing plug 4. After cleaning, the impurities can be separated from the filter screen 5 in time.

[0027] The servo motor 14 is powered by an external solar panel and is electrically connected to an external controller. A flow detector is installed inside the pipe 1.

[0028] The exhaust fan 2 is powered by an external solar panel and is electrically connected to an external controller. The external controller controls the exhaust fan 2 to operate intermittently, thus intermittently accelerating the ventilation efficiency of the mushroom house. This intermittent operation achieves ventilation while avoiding prolonged, unproductive operation. The exhaust fan 2 and servo motor 14 are primarily powered by the solar panel, with a battery serving as a backup power source to ensure the device can still operate when sunlight is insufficient.

[0029] A pressure sensor installed inside pipe 1 monitors the pressure difference or ventilation efficiency across filter 5. When a risk of blockage is detected, the servo motor 14 is automatically activated to drive the self-cleaning system; or a timed cleaning program can be set to balance cleaning effectiveness and energy consumption. A flow detector detects the airflow rate inside pipe 1. When the airflow rate is lower than a preset value, it indicates that pipe 1 is blocked. Therefore, the servo motor 14 is activated by an external controller to clean the filter.
