Description

Technical Field

[0001] This utility model relates to the field of agricultural and outdoor facility protection technology, and in particular to a snow and frost protection shed for the outdoor side of a greenhouse unit. Background Technology

[0002] With the development of modern agricultural technology, greenhouses have been widely used for off-season crop cultivation. In order to maintain a constant temperature environment inside the greenhouse, it is usually necessary to equip the outdoor side with corresponding heating or temperature control units. These outdoor units are exposed to the natural environment for a long time, especially in cold winter regions, where they are highly susceptible to wind, snow, and frost.

[0003] Current protective measures typically involve erecting simple snow shelters over the aircraft. However, most existing snow shelters have relatively simple and fixed structures, and their roof slope cannot be changed once designed. During severe blizzards, the fixed, gentle slope often fails to drain the accumulated snow in time, leading to excessive snow accumulation that can easily cause the roof to collapse or even damage the equipment below. Furthermore, existing protective shelters are often not easy to fold and store when not in use during the off-season, occupying a significant amount of storage space.

[0004] On the other hand, outdoor ground typically freezes into a hard permafrost layer in winter. Existing protective sheds are often installed and secured using ordinary, straight-inserted ground stakes driven into the ground. This method is extremely difficult to implement when facing permafrost or hard soil; the stakes are prone to bending and deformation and fail to penetrate deeply, resulting in insufficient grip. In windy conditions, the sheds are susceptible to tipping over or shifting. Furthermore, relying solely on physical slopes for snow prevention is limited in extreme low temperatures. Once snow freezes solid on the roof, it is difficult for it to slide off naturally, and there is a lack of proactive defrosting methods.

[0005] Therefore, this utility model proposes a snow and frost protection shed for the outdoor side of a greenhouse unit to address the shortcomings of the existing technology. Utility Model Content

[0006] In view of the problems existing in the technology of snow and frost protection sheds on the outdoor side of greenhouse units, such as single structure and function, fixed slope that cannot cope with different snowfall amounts leading to easy collapse of snow, difficulty in stable installation in frozen soil environment, lack of active snow melting and defrosting means, and low reliability, this utility model aims to provide a snow and frost protection shed on the outdoor side of greenhouse units with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a snow and frost protection shed for the outdoor side of a greenhouse unit, including: a main beam, an installation groove opened inside the main beam, a heating wire installed inside the installation groove, installation components symmetrically installed on both sides below the main beam, and a fixing component installed at the bottom of the installation components.

[0008] The installation assembly includes a first connecting rod and a second connecting rod. The top end of the first connecting rod is rotatably connected to the bottom of the main beam via a hinge. The top end of the second connecting rod is rotatably connected to the bottom end of the first connecting rod. An angle plate is provided at the connection between the first connecting rod and the second connecting rod. The angle plate is fixedly connected to the first connecting rod and the second connecting rod respectively by bolts.

[0009] Furthermore, the fixing component includes a side plate fixedly connected to the bottom end of the second connecting rod, a fixing block fixedly connected to the top of the side plate, an internal threaded hole opened inside the fixing block, a ground nail threaded inside the internal threaded hole, a spiral pattern provided on the outer wall of the ground nail, and the ground nail cooperates with the fixing block through the spiral pattern and extends through the side plate to the outside.

[0010] Preferably, the spiral pattern is divided into upper and lower parts along the axial direction of the ground nail. The upper part of the spiral pattern is located at the shaft of the ground nail and engages with the internal thread of the fixing block, while the lower part of the spiral pattern is located at the conical tip at the bottom of the ground nail. This segmented design utilizes the upper thread to provide stable rotational propulsion and the lower tip thread to achieve soil breaking and drilling, making it particularly suitable for hard frozen soil environments.

[0011] Preferably, a knob is fixedly connected to the top of the ground stake, the outer diameter of the knob being larger than the outer diameter of the ground stake, and the knob is located above the fixing block. This large-diameter knob design facilitates the operator's hand-held application of force and also serves to limit the screwing depth.

[0012] Preferably, the angle plate has a U-shaped structure and is sleeved on the outside of the connection between the first connecting rod and the second connecting rod. This wrapping structure enhances the structural strength of the connecting joint and prevents lateral torsion.

[0013] Preferably, the surface of the angle plate has several adjustment holes arranged in an arc shape. The bolt passes through the adjustment holes and is fixedly connected to the first connecting rod or the second connecting rod to lock the angle. The multi-hole design allows users to adjust the support slope in stages according to the amount of snow, realizing flexible changes in the structural form.

[0014] Preferably, the heating wire is wavy or linearly distributed along the length of the mounting groove, and the heating wire is fixedly installed on the inner wall of the mounting groove by a fixing clip. The wavy distribution effectively increases the heating area and improves the snow melting efficiency.

[0015] Preferably, the main beam has an inverted V-shaped cross-section, and the fixed end of the hinge is fixedly installed on the inclined surface at the bottom of the main beam. The inverted V-shaped cross-section itself has good snow guiding performance, and combined with the adjustable slope design, it further reduces snow accumulation.

[0016] Preferably, the mounting components are provided in multiple sets, and the multiple sets of mounting components are distributed at equal intervals along the length direction of the main beam. The multi-point support design ensures the uniformity of stress and stability of the overall structure.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of fixed slope of protective sheds in the prior art, which cannot cope with different snowfall and are inconvenient to store, by setting an installation component with an angle plate and a multi-segment rotating connecting rod. It achieves the technical effect of flexibly adjusting the slope of the shed roof according to the snowfall to facilitate snow discharge and prevent snow accumulation from collapsing. When not in use, it can be folded and stored to reduce the volume occupied and facilitate transportation and storage.

[0019] 2. This utility model solves the problem of ground nails being difficult to drive and not securely fixed in frozen or hard soil environments in winter by using a rotating ground nail with a spiral pattern and a fixing block with internal threads in the fixing component. It achieves the technical effect of easily screwing ground nails into hard soil layers by using the principle of rotational cutting, significantly reducing the difficulty of construction. At the same time, the spiral structure greatly improves the ground nail's grip and pull-out force on the soil, enhancing the wind resistance and stability of the device.

[0020] 3. This utility model solves the problem that existing technologies cannot cope with the freezing and sticking of snow under extreme low temperatures by simply relying on physical slope by opening an installation groove inside the main beam. It achieves the technical effect of actively generating heat to melt the frost on the surface of the main beam, destroying the adhesion of the snow, and causing the snow to slide off in one piece, thus achieving efficient snow and frost protection.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 5 This utility model provides a snow and frost protection shed for the outdoor side of a greenhouse unit, which aims to solve the problems in the prior art where the slope of the snow shed is not adjustable, causing snow to easily collapse, making storage inconvenient, and making it difficult to install stably in frozen soil environments.

[0031] like Figure 1 and Figure 2 As shown, the outdoor snow and frost protection shed of the greenhouse unit mainly consists of a supporting main body at the top, an adjustment mechanism supporting the overall structure, and an anchoring mechanism at the bottom. Specifically, it includes a main beam 1, an installation groove 5 opened inside the main beam 1, a heating wire 4 installed inside the installation groove 5, installation components 2 symmetrically installed on both sides below the main beam 1, and a fixing component 3 installed at the bottom of the installation components 2. The main beam 1, as the core load-bearing component of the entire device, has an inverted V-shaped cross-section to facilitate the natural sliding of snow. The installation groove 5 is opened along the length of the main beam 1 and is used to accommodate the heating element. The heating wire 4 is fixedly installed on the inner wall of the installation groove 5 by a fixing buckle, and the heating wire 4 is wavy or linearly distributed along the length of the installation groove 5 to generate heat in low-temperature environments to melt the snow or frost covering the top of the main beam 1, thereby realizing the active snow removal and frost prevention function.

[0032] Multiple sets of mounting components 2 are provided, evenly distributed along the length of the main beam 1. These components support the main beam 1 and transfer the load to the ground, while also providing angle adjustment and folding storage functions. Each set of mounting components 2 includes a first connecting rod 201 and a second connecting rod 203. The top end of the first connecting rod 201 is rotatably connected to the bottom of the main beam 1 via a hinge 202. The fixed end of the hinge 202 is fixedly installed on the inclined surface at the bottom of the main beam 1, allowing the first connecting rod 201 to deflect relative to the main beam 1. The second connecting rod 203... The top of 03 is rotatably connected to the bottom of the first connecting rod 201 to form a multi-segment folding structure. The fixing component 3 is located at the end of the second connecting rod 203 and is used to firmly anchor the entire protective shed in the soil. It includes a side plate 305 fixedly connected to the bottom of the second connecting rod 203. The side plate 305 is flat and its plane is perpendicular to the axial direction of the second connecting rod 203. A fixing block 303 is fixedly connected to the top of the side plate 305. The fixing block 303 cooperates with the specially made ground nail 301 to achieve effective gripping and fixing of hard soil or frozen soil.

[0033] To solve the above-mentioned technical problems, the outdoor snow and frost protection shed of the greenhouse unit also includes an angle adjustment mechanism. Furthermore, the angle adjustment mechanism forms a specific structural fit and connection relationship with the aforementioned first connecting rod 201 and second connecting rod 203 to realize the flexible adjustment of the slope of the protection shed and the function of storage and folding.

[0034] Please refer to the following carefully. Figure 3 The core structure will be described in detail below:

[0035] The angle adjustment mechanism is mainly composed of an angle plate 204 located at the joint connecting the first connecting rod 201 and the second connecting rod 203. The angle plate 204 has a U-shaped structure, and its inner width is adapted to the outer diameter of the first connecting rod 201 and the second connecting rod 203. The angle plate 204 is sleeved on the outside of the rotational connection between the first connecting rod 201 and the second connecting rod 203. Its function is to limit and lock the relative rotation angle between the first connecting rod 201 and the second connecting rod 203.

[0036] The surface of the angle plate 204 has several adjustment holes arranged in an arc shape. These adjustment holes are distributed in a fan shape around the rotation axis to provide different angle locking positions. During use, the first connecting rod 201 or the second connecting rod 203 has corresponding through holes. After the bolt 205 passes through any adjustment hole on the angle plate 204, it is then inserted into the through hole on the first connecting rod 201 or the second connecting rod 203. Finally, it is tightened and fixed by the nut. This multi-position pin hole connection method ensures that the user can flexibly select the appropriate adjustment hole to insert the bolt 205 according to the actual snowfall forecast, thereby changing the tilt angle of the first connecting rod 201 relative to the ground. When the outer adjustment hole is selected, the angle between the first connecting rod 201 and the ground increases, resulting in a steeper slope, which is conducive to the rapid sliding of snow accumulation in heavy snow and avoids accumulation and collapse. Conversely, it is suitable for light snow or no snow, maintaining the openness of the structure.

[0037] Meanwhile, when storage or transportation is required, simply loosen and remove bolt 205 to release the restriction of angle plate 204 on the rotation of connecting rod. The first connecting rod 201 and the second connecting rod 203 can then be folded freely around their rotation connection point, allowing the entire installation assembly 2 to be folded inward and fitted to the underside of the main beam 1. This greatly reduces the overall volume of the device and achieves the technical effects of quick disassembly and convenient carrying.

[0038] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0039] As a preferred embodiment, to address the challenges of stable installation on frozen or hard ground and to improve pull-out and wind resistance, please refer to the following: Figure 4 The fixing component 3 adopts a specially designed screw-in structure. The center of the fixing block 303 has a through internal threaded hole. The ground nail 301 is threadedly connected to the fixing block 303 through the internal threaded hole. The ground nail 301 passes through the plate 305 and extends to the outside. The outer surface of the ground nail 301 is machined with continuous spiral patterns 304. The spiral patterns 304 are divided into upper and lower parts with different functions along the axis of the ground nail 301. The upper part of the spiral patterns 304 is located in the cylindrical shaft area of ​​the ground nail 301. Its pitch and tooth profile match the internal threaded hole of the fixing block 303, which is used to generate a stable axial feed thrust during rotation. The lower part of the spiral patterns 304 is located in the conical tip area at the bottom of the ground nail 301. The thread profile of this part is sharper and has a cutting and drilling function similar to that of a self-tapping screw. It can easily cut into hard frozen soil or dense soil with the torque generated by rotation without the need for hammering, which greatly reduces the construction difficulty and improves the fixing depth and stability.

[0040] As another preferred embodiment, in order to facilitate the user's manual operation of screwing the ground nail 301 in and out, a knob 302 is fixedly connected to the top of the ground nail 301. The knob 302 is located above the fixing block 303, and the outer diameter of the knob 302 is designed to be larger than the outer diameter of the ground nail 301. This large diameter design not only increases the hand contact area and facilitates the application of rotational torque, but also plays a role in limiting and stopping, preventing the ground nail 301 from being excessively screwed into the fixing block 303.

[0041] As another preferred embodiment, in order to achieve the active snow melting and defrosting function and ensure that the snow accumulated on the top of the device can be cleared in a timely manner under extreme low temperature conditions, please refer to... Figure 2 and Figure 5 The main beam 1 has a through mounting groove 5 along its length. The cross-sectional shape of the mounting groove 5 is adapted to the mounting base of the heating wire 4. The heating wire 4 is evenly distributed in a wave-like or linear manner along the length of the mounting groove 5. This distribution method can increase the heating area and make the heat more evenly transferred to the entire top surface of the main beam 1. The heating wire 4 is firmly installed on the inner wall of the mounting groove 5 by a high-temperature resistant fixing buckle. After being powered by an external power source, the heating wire 4 heats up rapidly and heats the main beam 1 by using the principle of heat conduction. This breaks the frozen adhesion layer between the snow and the surface of the main beam 1. Combined with the slope design of the main beam 1 itself, it causes the snow to slide off in one piece.

[0042] The working principle of the outdoor snow and frost protection shed of this utility model greenhouse unit is as follows:

[0043] First, during the installation phase, the user pre-adjusts the slope of the protective canopy based on the current weather forecast or snow conditions. Specifically, the user unfolds the first connecting rod 201 and the second connecting rod 203, rotates the first connecting rod 201 to the required angle relative to the main beam 1, and the angle plate 204 rotates accordingly. After the angle is determined, the bolts 205 are inserted into the corresponding adjustment holes on the angle plate 204 and the through holes of the connecting rods and tightened. If a large amount of snow is predicted, the outer hole position is selected to increase the tilt angle of the first connecting rod 201, making the slope on both sides of the device steeper. This utilizes the component of gravity to make the snow slide down more easily, preventing the top snow from being too thick and collapsing the support.

[0044] Secondly, during the device fixing stage, especially when facing frozen soil or hard ground common in the north, the fixing component 3 is used for stable anchoring. The side plate 305 is placed in the predetermined installation position, and then the knob 302 is held to start rotating the ground nail 301. Since the spiral pattern 304 on the ground nail 301 and the internal threaded hole in the fixing block 303 interlock, the rotation is converted into a downward axial feed force. Combined with the self-tapping cutting action of the bottom tip of the ground nail 301, the ground nail 301 can easily and stably screw into the hard soil. As the ground nail 301 continues to go deeper, the fixing block 303 and the side plate 305 are pressed tightly onto the ground, thus providing strong pull-out resistance and wind resistance stability, and preventing the protective shed from shifting or tipping over even in bad weather.

[0045] Finally, during routine snow prevention and defrosting, when extreme low temperatures or prolonged snowfall cause snow on the top of the main beam 1 to be unable to slide off naturally and begin to freeze, the heating wire 4 located in the mounting groove 5 inside the main beam 1 is activated. After the heating wire 4 is powered on, it quickly generates heat, which is transferred to the outer surface of the main beam 1 through thermal conduction. This causes the ice layer or snow layer that is tightly attached to the surface of the main beam 1 to melt into water, thereby breaking the adhesion between the snow and the surface of the device. Under the action of gravity, the large snow on top will slide down the slope formed by the first connecting rod 201 to both sides of the device, realizing efficient active snow removal and defrosting functions, effectively protecting the equipment unit below from snow cover and freezing damage.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
