Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shielding doors, in particular to a shielding door with a passive drainage function. Background Art
[0002] The shield door is located in the radiation zone and is closed under normal operating conditions. When the water level on one side of the shield door rises, staff need to open the drain door on site to drain the water, which is inconvenient and affects the personal safety of personnel. Summary of the Invention
[0003] The purpose of the utility model is to solve the above technical problems and provide a shielding door with a passive drainage function.
[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the utility model is: a shielding door with a passive drainage function, comprising a door frame, a door leaf connected to the door frame by a hinge, a locking mechanism provided on one side of the door frame, and the opening and closing of the door leaf are realized by the locking mechanism, a drainage door is connected to the door leaf by a rotating shaft, a drainage door lock is provided at the bottom of the door leaf, a pulley is provided on the wall at the lower part of the door frame, a zipper A is provided on the pulley, a float A is provided at one end of the zipper A, and a counterweight block is provided at the other end, and the counterweight block is connected to the drainage door lock through the zipper B.
[0005] Preferably, an underground pulley is provided on the ground below the door frame, a zipper C passes through the bottom of the underground pulley and is provided on the drainage door lock at one end, and a float B is provided at the other end.
[0006] Preferably, the locking mechanism comprises pins that are evenly distributed, locking blocks are provided on the pins, a plurality of the locking blocks are connected by connecting rods, and an operating handle is provided on the pins.
[0007] Preferably, the drain door lock comprises a lock housing, wherein a lock tongue and a spring are arranged in the lock housing.
[0008] Compared with traditional structures, this new system offers the following advantages: a simple structure and a rational design. When the water level on one side of the shield door rises, the drain valve on the shield door is passively activated via a float mechanism, draining the accumulated water to the other side. This process eliminates the need for on-site personnel operation, ensuring personal safety. The use of a two-float system prevents damage to one float from causing the mechanism to malfunction, resulting in high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of the structure of the utility model;
[0010] In the figure: 1. Door leaf, 2. Door frame, 3. Hinge, 4. Drain door, 5. Rotating shaft, 6. Drain door lock, 7. Zipper B, 8. Pulley, 9. Counterweight, 10. Zipper A, 11. Float A, 12. Buried pulley, 13. Float B, 14. Zipper C, 15. Locking mechanism. DETAILED DESCRIPTION
[0011] The utility model is further described below.
[0012] Refer to the attached Figure 1 A shield door with passive drainage function includes a door frame 2, a door leaf 1 is connected to the door frame 2 through a hinge 3, a locking mechanism 15 is provided on one side of the door frame 2, and the door leaf 1 is opened and closed by the locking mechanism 15, a drainage door 4 is connected to the door leaf 1 through a rotating shaft 5, a drainage door lock 6 is provided at the bottom of the door leaf 1, a pulley 8 is provided on the wall at the lower part of the door frame 2, and a zipper A10 is provided on the pulley 8, a float A11 is provided at one end of the zipper A10, and a counterweight block 9 is provided at the other end, and the weight of the float A11 is balanced by the counterweight block, and the counterweight block 9 is connected to the drainage door lock 6 through a zipper B7.
[0013] In this preferred embodiment, an underground pulley 12 is provided on the ground below the door frame 2, a zipper C14 passes through the bottom of the underground pulley 12 and is provided on the drainage door lock 6 at one end, and a float B13 is provided at the other end.
[0014] In this preferred embodiment, the locking mechanism 15 includes evenly distributed pins, each of which is provided with a locking block. Several of the locking blocks are connected by a connecting rod, and an operating handle is provided on the pin.
[0015] In this preferred embodiment, the drain door lock 6 includes a lock housing, and a lock tongue and a spring are arranged in the lock housing.
[0016] In practice, a passive activation system with a float mechanism is employed, with floats A11 and B13 acting as a backup to prevent either from becoming inoperable due to damage. When the water level rises on one side of the shield door, float A11 rises, driving the counterweight 9 downward to pull the drain door lock 6 open. The drain door 4 rotates along the shaft 5 under the influence of the water flow, achieving drainage. In another embodiment, when the water level rises on one side of the shield door, float B13 rises, zipper C14 pulls the lock, and the lock tongue compresses the spring downward, opening the drain door 4. After drainage is complete, the drain door 4 returns to its original position due to its own gravity. The float descends, causing the lock tongue to return to its original position due to the spring, and the drain door lock 6 closes.
[0017] The above embodiments of the present invention are merely examples to clearly illustrate the present invention, but are not intended to limit the scope of protection of the present invention. All equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
