[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a side-sliding bulkhead door system includes a door frame 1, a door body 2, and a door opening and closing mechanism. The door frame 1 is mounted on the bulkhead. The door opening and closing mechanism includes a drive mechanism, a moving track 4, and a locking mechanism. Moving tracks 4 are provided on both the upper and lower sides of the door body 2. Each moving track 4 includes two parallel sub-tracks. Each sub-track includes a translation area 41 and a turning area 42. Each sub-track is connected to the door frame 1 via the turning area 42. Guide wheels 21 are provided between the sub-tracks and the door body 2. The drive mechanism includes a drive actuator 31. The drive actuator 31 includes a fixed end and a movable end. The fixed end is connected to the bulkhead, and the movable end is connected to the door body 2. The locking mechanism is located between the door frame 1 and the door body 2. A single drive actuator 31 drives the door body 2 to reciprocate along the track, thus opening and closing the door. When the bulkhead door is closed, the locking mechanism locks the door, at which point the drive actuator 31 can be de-energized to save energy.

[0025] In this embodiment, a guide wheel 21 is provided between the door body 2 and each sub-track of the upper and lower moving tracks 4 (two sub-tracks on each side, for a total of four guide wheels 21), which can ensure that the door body 2 slides smoothly along the moving track 4; the drive actuator 31 pushes the door body 2 to move, and the guide wheels 21 gradually approach the door frame 1 after passing the turning area 42, guiding the door body 2 to move closer to the door frame 1, and finally the door body 2 is embedded in the door frame 1 to achieve complete closure; the moving track 4 with the L-shaped turning area 42 can complete the opening and closing action with only a single drive actuator 31, and in the closed state, the door body 2 is embedded in the body, and the surface is flatter than that of a conventional sliding door, which is more conducive to maintaining a seal and occupies less space.

[0026] In this embodiment, the locking mechanism includes a locking actuator 51 and a lock hole; wherein the locking actuator 51 is fixed on the bulkhead and a locking pin 52 is provided at its tail end; the lock hole is provided on the door body 2 and corresponds one-to-one with the locking pin 52; when the door body 2 is closed in place, the locking actuator 51 is activated to insert the locking pin 52 into the lock hole, and the bulkhead door is locked.

[0027] In practical applications, the drive actuator 31 and the locking actuator 51 are hydraulic cylinders; the fixed end is hinged to the bulkhead and the movable end is hinged to the door body 2. When the door is opened or closed, there is no interference between the locking actuator 51 and the door body 2.

[0028] To improve the sealing performance of the bulkhead door, a sealing ring 11 is provided on the door frame 1 and a sealing strip 22 is provided on the outer edge of the door body 2. After the bulkhead door is closed, the sealing ring 11 and the sealing strip 22 fit tightly together, which can enhance the sealing effect and also provide a certain degree of buffer when the bulkhead door is closed.

[0029] In practical applications, a position sensing system is also included to detect the opening and closing status of the bulkhead door. The position sensing system mainly consists of several position sensors. In practical applications, the position sensors are placed in positions that can detect at least two states: the bulkhead door is fully closed and fully open. Furthermore, position sensors can be set in some specific locations as needed to detect different opening degrees, such as a half-open state. The opening and closing status of the bulkhead door can be detected through the position sensors to achieve fully automatic opening, closing and sealing actions.

[0030] In this embodiment, the guide wheel 21 is a universal wheel, which facilitates the movement of the door body 2 along the track of the sub-track; alternatively, other mechanisms that can move back and forth along a predetermined track can also be used instead.

[0031] Advantages of this utility model:

[0032] The structure is simple and compact, occupies little space, and is easy to maintain. The opening and closing action of the bulkhead door is smooth. The sub-rail has a turning area, which can guide the bulkhead door into the door frame, improve the airtightness, and can realize the opening and closing action of a single hydraulic cylinder, reducing the complexity of the equipment. It is equipped with a locking mechanism to keep the bulkhead door in the closed state and maintain the seal.

[0033] 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.
