Description

Technical Field

[0001] The utility model relates to the technical field of shielding doors, in particular to a shielding door with a 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 shield door with 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 drainage function, comprising a door frame, a door leaf connected to the door frame via a hinge, a locking mechanism provided on one side of the door frame, and the door leaf is opened and closed by the locking mechanism, a drainage door is connected to the door leaf via a rotating shaft, a counterweight is provided at the upper inner end of the drainage door, a reset mechanism is provided on the door frame, and the reset mechanism includes a reset motor, one end of the transmission assembly is connected to the reset motor, and the other end is connected to the rotating shaft.

[0005] Preferably, the transmission assembly includes a connecting rod A, a connecting rod B, and a connecting rod C, wherein the connecting rod A and the connecting rod B, and the connecting rod B and the connecting rod C are hinged.

[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] Compared with the traditional structure, the beneficial effects of the utility model are: simple structure, reasonable design, the drainage door on the shielding door is remotely activated by an electric mechanism to discharge the accumulated water to the other side of the door. This process does not require on-site operation by personnel, which plays a role in protecting the personal safety of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below.

[0012] Refer to the attached Figure 1-2 A shield door with 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 7 is provided on one side of the door frame 2, and the door leaf 1 is opened and closed by the locking mechanism 7, a drainage door 4 is connected to the door leaf 1 through a rotating shaft 5, a counterweight 8 is provided at the upper end of the inner side of the drainage door 4, and a reset mechanism 6 is provided on the door frame 2, and the reset mechanism includes a reset motor 61, and one end of the transmission assembly 62 is connected to the reset motor 61, and the other end is connected to the rotating shaft 5.

[0013] In this preferred embodiment, the transmission assembly 62 includes a connecting rod A, a connecting rod B, and a connecting rod C. The connecting rod A and the connecting rod B, and the connecting rod B and the connecting rod C are hinged.

[0014] In this preferred embodiment, the locking mechanism 7 includes evenly distributed pins 74, and locking blocks 73 are provided on the pins 74. Several locking blocks 73 are connected by connecting rods 72. An operating handle 71 is provided on the pins 74. By bending the operating handle 71, the connecting rod is moved to the corresponding position of the door leaf 1 to open or close the door leaf 1.

[0015] In practice, the screen door leaf 1 and drain door 4 are normally closed. When the water level on one side of the screen door rises, the reset mechanism 6 is remotely activated, the motor is energized, and the drain door 4, under the action of the counterweight 8, rotates about the shaft 5, draining the accumulated water to the other side of the door. Once the accumulated water is drained, the reset motor 61 drives the drain door shaft 5 through the transmission assembly 62, resetting the drain door 5. This process eliminates the need for on-site operator intervention, ensuring personal safety.

[0016] 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.
