[0075] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0076] This utility model provides a container (not shown). The container can be used to install equipment such as water treatment equipment. The container includes large-size waterproof double doors. These large-size waterproof double doors are at least waterproof. The large-size waterproof double doors are located at the ends of the container. Of course, in some other applications, the large-size waterproof double doors can be located on the sides of the container.

[0077] The following will refer to Figures 1 to 9 This invention provides a detailed description of a large-size waterproof double-leaf door according to an embodiment of the present invention. In the following description, the first horizontal direction D1 can be understood as the width direction of the door frame assembly 100, the second horizontal direction D2 can be understood as the front-to-back or inside-out direction of the door frame assembly 100, and the vertical direction D3 can be understood as the height direction of the door frame assembly 100. In the application state where the door frame assembly 100 is assembled at the end of a container, the first horizontal direction D1 is the width direction of the container, the second horizontal direction D2 is the length direction of the container, and the vertical direction D3 is the height direction of the container. The door leaf assembly 120 is pivotally mounted to the side structure of the door frame assembly 100 via a door hinge 160. When the door leaf assembly 120 is in the closed state, the width direction of the door leaf assembly 120 is consistent with the first horizontal direction D1, and the thickness of the door leaf assembly 120 is consistent with the second horizontal direction D2.

[0078] The large-size waterproof double door according to this embodiment may include a door frame assembly 100 and a door leaf assembly 120. The door frame assembly 100 encloses a door opening. The upper part of the door frame assembly 100 is provided with a top water guide channel 101a and a top receiving channel 101b extending along a first horizontal direction D1. The top water guide channel is located below the top receiving channel 101b along a vertical direction D3. The opening of the top water guide channel faces upward along the vertical direction D3 and communicates with the top receiving channel 101b. The opening of the top receiving channel 101b faces outward along a second horizontal direction D2 towards the door frame assembly 100. The first horizontal direction D1, the second horizontal direction D2, and the vertical direction D3 are mutually perpendicular. The door leaf assembly 120 is pivotally connected to the door frame assembly 100. The dimensions of the door leaf assembly 120 are larger than those of a conventional door leaf. The width of a conventional door leaf is typically 1m, and the height is typically 2m. Therefore, the width of the door leaf assembly 120 is greater than 1m. The height of the door leaf assembly 120 is greater than 2m. The door assembly 120 includes a door body 121 and a top water-blocking member 122. One end of the top water-blocking member 122 is connected to the top of the door body 121.

[0079] When the door assembly 120 is in the closed state, the other end of the top water-blocking member 122 is received in the top receiving groove 101b and is located above the top water guide groove 101a. The other end of the top water-blocking member 122 can be understood as the end of the top water-blocking member 122 that is away from the door body 121.

[0080] According to the embodiments of this application, a large-size waterproof double door is constructed by providing a top water guide groove 101a and a top receiving groove 101b in the door frame assembly 100, and a top water-blocking member 122 in the door leaf assembly 120. When the door leaf assembly 120 is closed, the end of the top water-blocking member 122 away from the door leaf body 121 is received in the top receiving groove 101b and located above the top water guide groove 101a. When the door leaf assembly 120 is closed, in rainy or other environments with water or other liquids, when water or other liquids enter from the top of the door leaf assembly 120, the water or other liquids will be received by the top water guide groove 101a and guided along the first horizontal direction D1 towards both ends of the door frame assembly 100. This reduces or prevents water or other liquids from entering the inside of the door frame assembly 100 through the space between the top of the door leaf assembly 120 and the door frame assembly 100, thereby achieving waterproofing.

[0081] Optionally, the top water-blocking member 122 includes a fixing portion 122a, an end portion 122b, and a supporting portion 122c. The fixing portion 122a extends along the vertical direction D3 and connects to the top of the door leaf body 121. The end portion 122b extends at least along the vertical direction D3. For example, the end portion 122b can be arranged vertically, inclined, or in other forms. The end portion 122b is spaced apart from the door leaf body 121 in the vertical direction D3. The end portion 122b is spaced apart on the inner side of the fixing portion 122a in the thickness direction. The supporting portion 122c connects to the upper end of the fixing portion 122a and the upper end of the end portion 122b.

[0082] When the door assembly 120 is in the closed state, the end portion 122b is received in the top receiving groove 101b and is located above the top water guide groove 101a.

[0083] For example, the side of the door frame assembly 100 is provided with a side water guide channel (not shown) extending in the vertical direction D3. The side water guide channel communicates with the top water guide channel 101a. By providing the side water guide channel, it helps to guide water in the top water guide channel 101a to the bottom of the door frame assembly 100, thereby improving drainage efficiency. At the same time, it can also reduce the probability of water seeping inward from both ends of the top water guide channel 101a to a certain extent.

[0084] Optionally, the side of the door frame assembly 100 is provided with a side receiving groove (not shown) extending in the vertical direction D3. A side water guide channel is located on the side of the side receiving groove near the door opening. The side water guide channel communicates with the side receiving groove. The opening of the side receiving groove faces outward. The door leaf assembly 120 also includes a side water-blocking member 123. The side water-blocking member 123 is located on the side of the door leaf assembly 120 near the door frame assembly 100. When the door leaf assembly 120 is closed, the side water-blocking member 123 is at least partially received in the side receiving groove. By providing the side receiving groove, the shielding area of ​​the door leaf assembly 120 over the door frame assembly 100 can be increased, which helps to prevent water from entering the inner side of the door frame assembly 100 from between the side of the door leaf assembly 120 and the door frame assembly 100, further improving the waterproofing effect.

[0085] Optionally, the door frame assembly 100 includes a top waterproof frame 101. The top waterproof frame 101 includes a first vertical wall 101c, a second vertical wall 101d, and a bottom wall 101e. The first vertical wall 101c is located inside the second vertical wall 101d. The first vertical wall 101c and the second vertical wall 101d are spaced apart along a second horizontal direction D2. The first vertical wall 101c is higher than the second vertical wall 101d, and the second vertical wall 101d is lower than the end portion 122b. The bottom wall 101e is connected to the lower end of the first vertical wall 101c and the lower end of the second vertical wall 101d. The first vertical wall 101c, the second vertical wall 101d, and the bottom wall 101e together form a top water guide groove 101a. The large-size waterproof double door includes a top waterproof strip 102, which is fixed to the second vertical wall 101d. When the door panel assembly 120 is in the closed state, the top waterproof strip 102 is sealed to the fixing part 122a. When the door panel assembly 120 is in the closed state, the top waterproof strip 102 is used to improve the sealing between the upper part of the door panel assembly 120 and the door frame assembly 100, and can prevent water accumulated in the top water guide groove 101a from entering the inside of the door panel assembly 120 and the door frame assembly 100 through the gap between them.

[0086] The top waterproof sealing strip 102 can be made of existing sealing strips, such as sealing strips made of soft elastic materials like rubber. This also helps to buffer the impact force of the door panel 120 when the door is closed, achieving the purpose of preventing rigid impacts and reducing vibration and noise.

[0087] Furthermore, the door frame assembly 100 includes a side waterproof frame 104. The structure of the side waterproof frame 104 can be the same as that of the top waterproof frame 101. The side waterproof frame 104 is located on the side of the door frame assembly 100 and is arranged correspondingly to the side water-blocking member 123. The side waterproof frame 104 is provided with a side water guiding groove and a side receiving groove. The two side waterproof frames 104 are fixed to both ends of the top waterproof frame 101, forming a U-shaped frame structure that is rotated 180°.

[0088] For example, a large-sized waterproof double door includes a rain gut 103 extending along a first horizontal direction D1. The rain gut 103 has a head end and an end end spaced along a second horizontal direction D2. The head end of the rain gut 103 is fixed to the door frame assembly 100. The end end of the rain gut 103 is located outside the door frame assembly 100. The rain gut 103 is higher than the door leaf assembly 120. By adding the rain gut 103, the probability of rainwater or other liquids penetrating between the top of the door leaf assembly 120 and the door frame assembly 100 can be further reduced, thereby improving the waterproof effect.

[0089] Optionally, the first end of the rain eaves 103 is fixed to the door frame assembly 100. The last end of the rain eaves 103 is lower than the first end.

[0090] Preferably, the eaves 103 is a sheet metal part. The portion of the eaves 103 protruding from the door frame assembly 100 has at least one bend. The bend is directed downwards. Increasing the bend improves the structural strength of the eaves 103.

[0091] For example, the door panel assembly 120 also includes a bottom water-blocking member 124. The bottom water-blocking member 124 protrudes from the bottom of the door panel body 121. The bottom water-blocking member 124 extends along a first horizontal direction D1 and forms an upward-opening groove 124b. A drain hole 124a is provided at the bottom of the bottom water-blocking member 124 corresponding to the groove 124b. The bottom water-blocking member 124 is used to block the gap between the door panel body 121 and the threshold member 105 to reduce the entry of rainwater, wind, etc. By providing the drain hole 124a, it is convenient to drain the water accumulated in the groove 124b.

[0092] Exemplarily, the door frame assembly 100 includes a threshold member 105. The threshold member 105 includes a first step portion 105a, a second step portion 105b, a first step support portion 105c, and a second step support portion 105d. The first step portion 105a is closer to the outer side of the door frame assembly 100 than the second step portion 105b in a second horizontal direction D2. The first step portion 105a is lower than the second step portion 105b. The first step support portion 105c is connected to the end of the first step portion 105a away from the second step portion 105b and extends downward in a vertical direction D3. The first step support portion 105c is connected between the adjacent ends of the first step portion 105a and the second step portion 105b and extends in a vertical direction D3. In a plane perpendicular to the vertical direction D3, the projection of the top water-blocking member 122 is at least partially located between the first step support portion 105c and the second step support portion 105d. When the door assembly 120 is in the closed state, the drain hole 124a is aligned with the first step portion 105a. By providing a stepped threshold member 105, it is beneficial to prevent water and other foreign objects from entering the inside of the closed door assembly 120 from below. At the same time, by aligning the drain hole 124a at the bottom of the door assembly 120 with the first step portion 105a, it is beneficial for the drained water to flow outwards, and the second step support portion 105d prevents water from flowing into the inside of the door frame assembly 100.

[0093] For example, in the application of a large-size waterproof double-leaf door to a container, if the container shakes during transportation, the door assembly 120 may open. To avoid this problem, the large-size waterproof double-leaf door according to an embodiment of this application includes a stop 151, a first fastening connector 152, and a second fastening connector 153. The stop 151 is adapted to be disposed on the outside of the door frame assembly 100. The stop 151 has a connecting hole. The first fastening connector 152 is fixed to the sill member 105. The second fastening connector 153 is adapted to be detachably connected to the first fastening connector 152. One of the first fastening connector 152 and the second fastening connector 153 is adapted to pass through the connecting hole to fasten the stop 151 to the door frame assembly 100. With the door assembly 120 in the closed state, the stop 151 is installed onto the door frame assembly 100 through the cooperation of the first fastening connector 152 and the second fastening connector 153. At this time, the stop 151 is located on the outside of the door assembly 120 and can prevent the door assembly 120 from opening. When the container is in normal use, the stop 151 can be removed.

[0094] Optionally, the first fastening connector 152 is a blind nut, i.e., a nut with a blind threaded hole. Welding the blind nut to the sill member 105 helps reduce the probability of water seepage at the sill. The second fastening connector 153 is a bolt.

[0095] For example, a large-sized waterproof double door includes a door assembly 120 with louvers 125a and an auxiliary door 125b. The louvers 125a are adapted to connect opposite sides of the door body 121, and the auxiliary door 125b is operablely disposed at the louvers 125a. The auxiliary door 125b is located on the side of the louvers 125a facing inwards towards the door assembly 120, and is adapted to be operated by a user from the inside to open or close. When the auxiliary door 125b is open, the louvers 125a allow ventilation. When the auxiliary door 125b is closed, the louvers 125a cannot provide ventilation or provide adequate ventilation.

[0096] For example, the large-size waterproof double doors include a door assembly 120 with an operable access door 126. By providing the access door 126, routine maintenance can be performed by opening the access door 126 to enter the container. This operation is more effortless and convenient compared to opening the door assembly 120 itself.

[0097] In some embodiments, each of the two door leaf assemblies 120 in a pair of door leaf assemblies 120 is provided with a louver 125a and an auxiliary door 125b.

[0098] In other embodiments, one door assembly 120 of a pair of door panels is provided with an access door 126, and the other door assembly 120 is provided with louvers 125a and an auxiliary door 125b.

[0099] Optionally, one of the pair of door leaf assemblies 120 is provided with a door leaf sealing strip 127. The door leaf sealing strip 127 is arranged vertically. The other door leaf assembly 120 is provided with a door leaf sealing surface that engages with the door leaf sealing strip 127.

[0102] Preferably, each part of the door frame assembly 100 can be made of steel. The door frame assembly 100 is a steel structure frame assembled and welded from various steel components. This frame ensures the overall strength and durability of the door opening, resists the influence of harsh external environmental factors, and ensures that the equipment inside the enclosure is not damaged.

[0103] Optionally, the door assembly 120 includes an outer door panel 121a, an inner door panel 121b, and a door frame 121c connecting the two. The aforementioned top water-blocking member 122, side water-blocking member 123, and bottom water-blocking member 124 are all part of the outer door panel 121a. This ensures the integrity of the outer door panel 121a and improves the waterproofing effect.

[0104] To enable deadbolting of the door assembly 120 from the inside, a large-size waterproof double door according to an embodiment of this application includes a bolt assembly 140. The bolt assembly 140 includes a separable pin member 141 and a receiving member 142. The pin member 141 is disposed on the door assembly 120. The receiving member 142 is disposed on the door frame assembly 100. The distance between the pin member 141 and the threshold member 105 of the door frame assembly 100 in the vertical direction D3 is less than or equal to 2m, making it easier for the user to access and operate.

One set of latch assemblies 140 is located on the upper part of the door leaf assembly 120, and the other set of latch assemblies 140 is located on the lower part of the door leaf assembly 120. The pin member 141 of the latch assembly 140 located on the upper part of the door leaf assembly 120 is elongated, so that the distance between the pin member 141 and the threshold is closer, thus making it easier for the user to operate.

[0106] In related technologies, container doors typically use lever-type locks. It is well known that lever-type locks are quite laborious to operate for non-professionals and are easily corroded by rainwater, affecting the overall aesthetics of the container. Therefore, the large-size waterproof double-leaf door according to this embodiment includes a door lock assembly 130. The door lock assembly 130 includes a separable first door lock component 131 and a second door lock component 132. The first door lock component 131 is located on one door leaf assembly 120. The second door lock component 132 is located on the other door leaf assembly 120. When the door leaf assembly 120 is closed, locking the door is achieved by locking the first door lock component 131 located on one door leaf assembly 120 with the second door lock component 130 located on the other door leaf assembly 120. Compared to lever-type locks, this locking operation is more convenient. Correspondingly, unlocking this type of lock is also more convenient than lever-type locks.

[0107] Optionally, the door lock assembly 130 can be a door lock such as a cold storage door lock in the prior art, especially a door lock that is easy for users to unlock from the inside of the container, which makes it easier for users to escape in an emergency.

[0108] When the door panel assembly 120 is in the closed state, the outer surface of the door panel assembly 120 may be flush with the outer surface of the door frame assembly 100.
