Description

Technical Field

[0001] The invention relates to the technical field of port engineering, and in particular to a novel automatic opening and closing system for a top loading port of a dry bulk container. Background Art

[0002] As a common medium for bulk cargo transportation, dry bulk containers are widely used in the industry. Currently, dry bulk containers come in different forms, but basically they all have holes on the top of the container as loading ports for bulk cargo, and are equipped with covers. Before and after loading, the on-site operator needs to climb onto the top of the container to operate. The opening and closing of the movable top cover of the container is basically independent, and each cover needs to be opened and closed. The operating efficiency is low, the sealing is poor, and there are certain safety hazards when the staff go up and down.

[0003] For example, the Chinese invention patent application with publication number CN 112478468 A discloses a dry bulk container and a method for unloading the same. A retaining wall is fixed on the inner side of the door of the dry bulk container, and a discharge port is provided at the lower part of the retaining wall. The unloading method is to combine blowing air into the box body with turning over the dry bulk container so that the discharge port is tilted downward or vertically downward, or to combine blowing air into the box body, turning over the dry bulk container so that the discharge port is tilted downward or vertically downward, and sucking the dry bulk cargo from the discharge port using a suction device. In this way, the dry bulk cargo can be prevented from gushing out after the door is opened, which will not pollute the air or endanger the health of the unloading personnel. In addition, the dry bulk cargo discharged through the discharge port is better collected. At the same time, the unloading speed and efficiency can be increased by combining the unloading method with the blowing and suction methods, thereby saving transportation costs. However, the feed port of the container is opened separately on the movable top cover. The on-site operator needs to climb onto the top of the container to operate before and after the loading operation. The opening and closing of the movable top cover of the container are basically independent, and each cover needs to be opened and closed, resulting in low operating efficiency and poor sealing. Summary of the invention

[0004] In order to solve the above-mentioned technical defects existing in the prior art, the purpose of the present invention is to provide a new automatic opening and closing system for the top loading port of a dry bulk container, which reduces the labor intensity of opening and closing operations of the top loading port of the dry bulk container, avoids the risks of high-altitude operations, and improves the efficiency of loading operations; the photovoltaic and energy storage modules on the top of the container provide power for the automatic opening and closing of the top loading port of the dry bulk container, and the electricity is self-generated and self-used, which is green and environmentally friendly.

The top cover is designed as a movable top cover, so that the opening and closing of the top loading port 2 is more convenient.

[0024] See also Figure 3 As shown, the new automatic opening and closing system for the top loading port of a dry bulk container according to the present invention Figure 1 A schematic diagram of the front structure of the preferred embodiment is shown.

[0025] In this embodiment, tracks 5 are provided on both sides of the box top loading port 2, the mobile top cover 3 is placed on the tracks 5, and rolling wheels are provided below the mobile top cover 3, and the rolling wheels drive the mobile top cover 3 to move left and right on the tracks 5; an anti-derailment device 13 is provided on one side of the rolling wheel to prevent the traction chain 10 from derailing when the mobile top cover 3 is pulled; and stoppers 6 are provided at both ends of the track 5 to limit the mobile top cover 3. The stopper 6 is used to limit the mobile top cover 3 when the box top loading port 2 is opened to prevent the mobile top cover 3 from moving beyond the limit.

[0026] In this embodiment, the top of the box body 1 is also provided with a photovoltaic and energy storage module 12 (see Figure 4 shown).

[0027] In this embodiment, the top transmission system includes a driving flywheel 8, a driven flywheel 9, a traction chain 10 and a three-in-one motor 11. The three-in-one motor 11 is installed in a groove on the top of the container body 1, and its output shaft is perpendicular to the top of the container body 1 and upward, and can be reversed. The three-in-one motor 11 is driven by a photovoltaic and energy storage module 12 (see Figure 4 When working, the output shaft of the three-in-one motor 11 is connected to the active flywheel 8, and the active flywheel 8 and the driven flywheel 9 are both connected in series with a traction chain 10, which drives the movable top cover 3 to move along the track 5. When the on-site operator operates through the wireless remote control 14, the movable top cover 3 can be controlled to move along the track 5, thereby controlling the opening and closing of the box top loading port 2.

[0028] In this embodiment, a gear is provided on one side of the movable top cover 3 , and the gear is meshed with the traction chain 10 . Through the traction transmission of the traction chain 10 , the movable top cover 3 slides on the box top tracks on both sides of the box top loading port 2 .

[0029] In this embodiment, the active flywheel 8 and the driven flywheel 9 are respectively arranged on both sides close to the box door, and are connected in series at the outer edge by a traction chain 10. The active flywheel 8 is driven by a three-in-one motor 11.

[0031] In this embodiment, the contact point between the buckle device 7 and the top loading port 2 is arc-shaped, which is in a downward pressing state under normal conditions. When the movable top cover 3 contacts the buckle device 7 and continues to move forward, the movable top cover 3 pushes up the buckle device 7, thereby compacting the movable top cover 3. The buckle device 7 is used to redundantly fix the movable top cover 3 when the top loading port 2 is closed.

[0032] The working principle of the novel automatic opening and closing system of the top loading port of the dry bulk container of the present invention is as follows: when working, the operator operates the wireless remote control 14 on the ground nearby. When the top loading port 2 of the container needs to be closed, the photovoltaic and energy storage module 12 provides energy for the three-in-one motor 11. The three-in-one motor 11 rotates forward to drive the active flywheel 8 and the driven flywheel 9 to rotate, so that the traction chain 10 drives the movable top cover 3 to move along the track 5. When the movable top cover 3 contacts the top loading port 2 of the container and continues to move forward, the buckle device 7 is lifted up, and then the movable top cover 3 is compacted, so that the top loading port 2 of the container is closed (see Figure 1When the top loading port 2 needs to be opened, the photovoltaic and energy storage module 12 provides energy for the three-in-one motor 11, and the three-in-one motor 11 reverses to drive the active flywheel 8 and the driven flywheel 9 to rotate, so that the traction chain 10 drives the movable top cover 3 to move in the opposite direction along the track 5. When the buckle device 7 sinks, the movable top cover 3 is separated from the top loading port 2, so that the top loading port 2 is opened (see Figure 2 shown).

[0033] Last read Figure 5 As shown, this is a working principle diagram of a wireless remote controller in the automatic opening and closing system of the top loading port of a new type of dry bulk container according to the present invention.

[0034] The working principle of the wireless remote control 14 is as follows: the wireless remote control 14 sends instructions to the three-in-one motor 11 (the electric energy of the three-in-one motor 11 comes from the photovoltaic power generation and energy storage module 12) through the wireless communication module, and the three-in-one motor 11 drives the transmission system to work, and finally moves the movable top cover 3.
