Description

Technical Field

[0001] This utility model relates to the field of veterinary equipment technology, and in particular to a cold-proof hanging door device for a large herbivore enclosure. Background Technology

[0002] Animal enclosures, such as those for rhinos, are designed and constructed using materials tailored to the animals' size, habits, and local climate. Cold-weather protection measures are also implemented based on the structure and requirements of the enclosure's doors and windows. These measures aim to stabilize or help raise the indoor temperature under controlled conditions, creating a comfortable environment for the animals and reducing the risk of illness or death due to cold. They also facilitate the work and safety of conservation staff.

[0003] Rhino enclosures typically have doorways in the walls, fitted with sliding, fence-like doors for entry and exit. To maintain temperature inside, these enclosures generally use tarpaulins for insulation. This involves cutting tarpaulins slightly larger than the doorway in height and width, attaching them to the side walls, and securing the tarpaulin to the top and bottom with galvanized pipes. When in use, the tarpaulin is opened, allowing the lower pipe to hang down and cover the doorway. When not in use, the tarpaulin is rolled up using the galvanized pipes for secure mounting. However, when these tarpaulins are lowered for use, strong winds or other inclement weather can blow them up, allowing cold air to enter the enclosure through the gaps, reducing their effectiveness in insulating against the cold. Traditional animal passageways also fail to guarantee the necessary ventilation and safety for rhino enclosures. Utility Model Content

[0004] Therefore, it is necessary to provide a cold-proof hanging door device for large herbivore enclosures that has better cold-proof effect and is easy to operate.

[0005] This application provides a cold-proof hanging door device for a large herbivore enclosure. The large herbivore enclosure includes a wall with a doorway. In one embodiment, the cold-proof hanging door device for the large herbivore enclosure includes:

[0006] Sliding doors, located on the interior side of a wall, are configured to move back and forth along the width of the doorway to open or close the doorway.

[0007] A hanging door, including a door panel, is located on the exterior side of the wall and is positioned corresponding to the door opening;

[0008] A suspension rope, connected to the top of the sliding door, is used to raise or lower the sliding door along the height of the doorway to open or close the doorway; and

[0009] The guide component, located on the exterior side of the wall, defines a sliding track extending along the height of the doorway, and the hanging door slides in conjunction with the sliding track.

[0010] In one embodiment, the cold-proof hanging door device for large herbivore enclosures also includes a hanging rope positioning element and at least two steering pulleys;

[0011] The steering pulley is fixed to the wall and located on the top side of the doorway;

[0012] One end of the hoisting rope is fixed to the hoisting gate, and the other end is detachably connected to the hoisting rope positioning component. The two ends of the hoisting rope are wound around at least two steering pulleys.

[0013] In one embodiment, the sling positioning member includes a base and a sling winding portion;

[0014] The base is used to connect to the wall, the rope winding part is connected to the base, and the middle of the rope winding part is provided with a recess for the suspension rope to be wound.

[0015] In one embodiment, the sliding door also includes a door frame connected to the door panel, and the door frame includes four connecting rods and one reinforcing rod;

[0016] The four connecting rods are connected end to end to form a closed frame structure, and the reinforcing rods are connected to the two connecting rods that are spaced apart from each other.

[0017] In one embodiment, the guide assembly includes a first guide rail and a second guide rail, which are disposed on the exterior side of the wall and located on both sides of the width direction of the door opening, respectively.

[0018] The first and second guide rails together define the sliding track.

[0019] In one embodiment, when the door is in its lowest position, the highest point of the door is higher than the lowest point of the first guide rail and the lowest point of the second guide rail.

[0020] In one embodiment, the height of the sliding door is lower than the height of the doorway;

[0021] The cold-proof hanging door system for large herbivore enclosures also includes a baffle that is placed on top of the doorway and partially covers it; when the hanging door is in its lowest position, the top of the hanging door at least partially overlaps with the baffle.

[0022] In one embodiment, each end of the baffle is fixed to the inner wall of the doorway by a positioning element.

[0023] In one embodiment, when the sliding door is in its lowest position, the overlap between the top of the sliding door and the baffle along the height direction of the door opening is greater than or equal to 10 cm.

[0024] In one embodiment, the bottom of the sliding door is provided with rollers and a limiting plate, with the limiting plate blocking both sides of the rollers along the axial direction;

[0025] Rollers are used to roll within tracks on the ground, and limiting plates are used to abut against the side walls of the tracks.

[0026] The beneficial effects of the aforementioned cold-proof hanging door system for large herbivore enclosures:

[0027] Sliding doors allow for easy opening and closing of the doorway, enhancing the safety of large herbivore enclosures. A suspension system with ropes connecting to the top of the door allows for raising and lowering the doorway along its height, opening or closing it. Therefore, when frost protection is needed, simply lowering the doorway prevents cold drafts from entering. When frost protection is not required, raising the doorway improves ventilation and ease of operation for large herbivore enclosures.

[0028] By incorporating a guide component that slides smoothly along a sliding track, the sliding door is prevented from swaying when wind blows. Compared to related technologies where the tarpaulin is easily lifted by the wind, the guide component positions the sliding door, eliminating gaps between it and the doorway. This results in superior cold-weather protection for the sliding door system in large herbivore enclosures. Attached Figure Description

[0052] Reference Figure 1 , Figure 2 The animal enclosure includes a wall 10 with a doorway 11 (shown as a dashed line in the figure). The cold-proof hanging door device 100 for large herbivore enclosures provided in this application embodiment (hereinafter also referred to as the cold-proof hanging door device 100) includes: a sliding door 20, a hanging door 30, a hanging rope 40, and a guide assembly 50.

[0053] A sliding door 20 is located on the interior side of the wall 10 and is configured to reciprocate along the width direction W of the doorway to open or close the doorway 11. A hanging door 30 includes a door panel 31 and is located on the exterior side of the wall 10, at a position corresponding to the doorway 11.

[0054] A suspension rope 40 is connected to the top of the sliding door 30. The suspension rope 40 is used to suspend or lower the sliding door 30 along the height direction H of the doorway 11 to open or close the doorway 11. A guide assembly 50 is located on the exterior side of the wall 10. The guide assembly 50 defines a sliding track extending along the height direction H of the doorway, and the sliding door 30 slides into the sliding track. The suspension rope 40 can be a 10mm rope.

[0055] The doorway 11 can be opened or closed by a sliding door 20. A suspension rope 40 and a hanging door 30 are also provided; the rope 40 is connected to the top of the hanging door 30. The rope 40 is used to raise or lower the hanging door 30 along the height H of the doorway to open or close the doorway 11. Therefore, when cold-proofing is required, simply lowering the hanging door 30 will cover the doorway 11 and prevent cold wind from entering. When cold-proofing is not required, simply raising the hanging door 30 will suffice.

[0056] By setting up the guide component 50, which slides in conjunction with the sliding track, the sliding door 30 can be prevented from swaying when the wind blows. Compared with related technologies where the tarpaulin is lifted by the wind, the sliding door 30 is positioned by the guide component 50, and there are no gaps between it and the door opening 11, resulting in a better cold-proof effect for the cold-proof sliding door device 100.

[0057] The door panel 31 can be made of a rigid material, such as a transparent rigid panel. This also facilitates observation of the animals inside the animal enclosure.

[0058] In this embodiment, the large herbivorous animal can be, for example, a rhinoceros, or other types of large herbivorous animals. In this embodiment, the rhinoceros enclosure is used as an example for illustration. Other types of large herbivorous animals are similar to rhinoceroses and will not be described in detail here.

[0059] In this embodiment, the cold-proof hanging door device 100 further includes a hanging rope positioning member 60 and at least two steering pulleys 70.

[0060] The steering pulley 70 is fixed to the wall 10 and located on the top side of the doorway 11. One end of the suspension rope 40 is fixed to the door 30, and the other end is detachably connected to the suspension rope positioning member 60. The two ends of the suspension rope 40 are wound around at least two steering pulleys 70.

[0061] Because the two ends of the lifting rope 40 are wound around the steering pulley 70, one end of the lifting rope 40 is fixed to the door 30, and the other end is detachably connected to the lifting rope positioning component 60. This allows the lifting rope positioning component 60 to be placed at a height convenient for the operator to operate. The other end of the lifting rope 40 can be detachably connected to the lifting rope positioning component 60 by changing the direction of the steering pulley 70. Even if the lifting rope 40 is connected to the door 30 at a high position, it can still be pulled by manipulating the other end of the lifting rope 40. In specific implementation, such as... Figure 2 As shown, there can be two steering pulleys 70, and the two steering pulleys 70 are at the same height and are spaced apart from each other. In this way, one end of the suspension rope 40 is connected to the top of the door 30, and the other end can be connected downward to the suspension rope positioning member 60 after two reversals.

[0062] In the embodiments of this application, reference is made to Figure 3 The suspension rope positioning component 60 includes a base 61 and a rope winding portion 62. The base 61 is used to connect to the wall 10, and the rope winding portion 62 is connected to the base 61. The rope winding portion 62 has a recessed portion 621 in the middle for the suspension rope 40 to be wound. That is, the suspension rope 40 can be wound circumferentially around the recessed portion 621.

[0063] In a specific implementation, the base 61 can be an angle steel, and the rope winding part 62 includes two spaced-apart transverse bars 622 and a longitudinal bar 623. The transverse bars 622 are spaced apart along the height direction H of the doorway, and the longitudinal bar 623 extends along the height direction H of the doorway. One end of each of the two transverse bars 622 is connected to the base 61, and the other end is connected to the longitudinal bar 623. The distance between the two transverse bars 622 is less than the length of the longitudinal bar 623. Thus, the two transverse bars 622, the base 61, and the longitudinal bar 623 together define a recess 621, which can be wound with the suspension rope 40.

[0064] In the embodiments of this application, reference is made to Figure 4 The hanging door 30 also includes a door frame 32, which is connected to the door panel 31. The door frame 32 includes four connecting rods 321 and one reinforcing rod 322.

[0065] Four connecting rods 321 are connected end to end to form a closed frame structure, and reinforcing rods 322 are connected to two connecting rods 321 that are spaced apart from each other.

[0066] Combination Figure 1 and Figure 4, the door frame 32 is used to provide strength support for the door panel 31. Among the four connecting rods 321, two of the connecting rods 321 extend along the width direction W of the door opening, and the other two connecting rods 321 extend along the height direction H of the door opening. Thus, the four connecting rods 321 are connected end to end to form a square-shaped structure. The reinforcing rod 322 can extend along the width direction W of the door opening, so that the door frame 32 forms a "day" - shaped structure. When the width of the door opening 11 is 1.8 meters and the height is 2.3 meters, the size of the door frame 32 can be 2 meters wide and 2 meters high. Thus, when the door panel 31 is connected to the door frame 32, the hanging door 30 can at least cover the entire part along the width direction W of the door opening 11.

[0067] The connecting rod 321 and the reinforcing rod 322 can be stainless steel square tubes with a caliber specification of 1.5 cm * 3 cm * 1 mm. That is, in the cross-section of the square tube, a size of 1.5 cm in width, 3 cm in length, and 1 mm in thickness is selected. The door panel 31 can be a transparent plate with a thickness of 1.5 mm and is fixed to the door frame 32 through fasteners such as screws. During specific operation, one side of the door frame 32 can face the outdoor side.

[0068] In the embodiment of the present application, continue to refer to Figure 1 , the guiding component 50 includes a first guide rail 51 and a second guide rail 52. The first guide rail 51 and the second guide rail 52 are arranged on the outdoor side of the wall 10 and are respectively located on both sides of the width direction W of the door opening. The first guide rail 51 and the second guide rail 52 jointly define a sliding track.

[0069] With such a setting, when pulling the hanging rope 40, the hanging rope 40 can carry the hanging door 30 to rise along the height direction H of the door opening, gradually opening the door opening 11. When the hanging rope 40 is lowered, the hanging door 30 can fall along the sliding track under the action of gravity until it reaches the ground.

[0070] In specific implementation, the first guide rail 51 and the second guide rail 52 can be angle irons respectively. The lengths of the first guide rail 51 and the second guide rail 52 can be set to 80 cm, and the heights of the first guide rail 51 and the second guide rail 52 from the ground can be set to 140 cm. Thus, when the height of the hanging door 30 is 2 m, when the hanging door 30 is pulled to the highest point, it will not脱离 the sliding track. In some embodiments, the first guide rail 51 and the second guide rail 52 can be fixed to the wall 10 through expansion screws and the like.

[0071] In the embodiment of the present application, the total height of the wall 10 can be, for example, 430 cm. The movable height of the hanging door 30 can be 400 cm.

[0072] In the embodiment of the present application, when the hanging door 30 is in the lowest position, the position of the highest point of the hanging door 30 is higher than the heights of the lowest points of the first guide rail 51 and the second guide rail 52. It should be noted that the expression "脱离" in the original text seems to be incorrect. I translated it as "脱离" as it was in the original, but it might be a misspelling. It could perhaps be "脱离" which means "depart from" or "get out of".

[0073] This configuration ensures that when the hanging door 30 is lowered, the highest point of the hanging door 30 remains within the first guide rail 51 and the second guide rail 52, preventing the hanging door 30 from detaching from the first guide rail 51 and the second guide rail 52.

[0074] Furthermore, the height of the sliding door 30 is lower than the height of the doorway 11. The frost-proof sliding door device 100 also includes a baffle 80, which is positioned at the top of the doorway 11 and partially covers it. The sliding door 30 is located as follows... Figure 1 At the lowest position shown, the top of the sliding door 30 at least partially overlaps with the baffle 80. The dimension of this overlap along the height direction H of the doorway is 10 cm.

[0075] Thus, the portion of doorway 11 not obscured by the hanging door 30 can be covered by the baffle 80. The baffle 80 also provides some wind protection. Furthermore, the outer side of the baffle 80 can be flush against the hanging door 30. The dimension H of the baffle 80 along the height of the doorway is approximately 40cm.

[0076] In this embodiment, each end of the baffle 80 is fixed to the inner wall of the doorway 11 by a positioning member 81.

[0077] In practice, one positioning component 81 is connected to one end of the baffle 80 and fixed to one inner wall of the door opening 11 using expansion screws or other fasteners. The other positioning component 81 is connected to the other end of the baffle 80 and fixed to the other inner wall of the door opening 11 using expansion screws or other fasteners. In this way, the baffle 80 can be positioned entirely inside the door opening 11. In actual installation, the baffle 80 can be positioned further inside the door than the sliding door 30.

[0078] Furthermore, the hanging door 30 is located in Figure 1 When the door is in its lowest position as shown, the overlap between the top of the sliding door 30 and the baffle 80 along the height direction of the doorway 11 is greater than or equal to 10 cm. This allows for better concealment of the doorway 11 when the sliding door 30 is lowered.

[0079] In the embodiments of this application, reference is made to Figure 2 The bottom of the sliding door 20 is equipped with rollers 90 and limiting plates 91. The limiting plates 91 are positioned on both sides of the rollers 90 along their axial direction. The rollers 90 are used to roll within a track (not shown) on the ground, and the limiting plates 91 are used to abut against the side wall of the track.

[0080] By setting a limiting plate 91, the roller 90 can be prevented from derailing during the rolling process within the track by the contact between the limiting plate 91 and the inner wall of the track.

[0081] Combination Figure 1 and Figure 2When it is necessary to lift the gate 30, the lifting rope 40 is detached from the lifting rope positioning piece 60 and pulled downwards to lift the gate 30. Figure 2 As shown, simply attach the hoisting rope 40 to the hoisting rope positioning piece 60. When it is necessary to lower the hanging door 30, detach the hoisting rope 40 from the hoisting rope positioning piece 60 and release it upwards. The hanging door 30 will fall to the ground due to its own weight, causing the hoisting rope 40 to move upwards.

[0082] Experiments have shown that the cold-proof hanging door device for large herbivore enclosures according to this application, when applied to rhinoceros enclosures, provides excellent wind protection, is durable, and has strong sealing properties. Using the same number of heaters, compared to related technologies that use tarpaulins for cold protection, the temperature inside the rhinoceros enclosure can rise by 3-6°C. Furthermore, the use of this cold-proof hanging door device facilitates operation for staff, improving their work efficiency.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
