Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0040] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0043] In order to meet the requirements of mandatory continuous mechanical ventilation, bulk carriers, container ships and other ships are equipped with shutters at the hatch cover of the cargo hold. When ventilation of the cargo hold surface or mandatory non-continuous ventilation is required, the hatch cover shutters are opened; when ventilation is not required, the shutters are closed.

[0044] like Figure 1As shown, the shutter 200 includes a hatch frame 240, a shutter body 210, a hatch cover 220 and a guide plate 250. The shutter body 210 is installed in the hatch frame 240. The guide plate 250 is rotatably connected to the hatch frame 240. A guide groove 2501 is provided on the guide plate 250. One end of the hatch cover 220 is rotatably connected to the hatch frame 240. The other end of the hatch cover 220 is provided with an ear buckle, which can slide along the guide groove 2501. The guide groove 2501 includes a linear groove area and a hook groove area. When the hatch cover 220 seals and covers the shutter body 210, the ear buckle is in the linear groove area. When the hatch cover 220 is opened, the ear buckle is in the hook groove area. Specifically, the linear groove area allows the ear buckle to move therein, so that the hatch cover 220 can be opened or closed under the guidance of the guide plate 250. When the hatch cover 220 is in an open state, the ear buckle will be in the hook groove area, so the ear buckle can be caught by the hook groove area, thereby preventing the ear buckle from falling back into the linear groove area and causing the hatch cover 220 to be closed by mistake.

[0045] Since the shutters 200 at the hatch covers 220 of the above-mentioned bulk carriers and container ships are located relatively high, such as Figure 2 As shown, when opening and closing the blinds 200, the operator needs to stand on a ladder, hold the handrail 230 with one hand, and operate with the other hand. However, the blinds 200 are too heavy to be opened and closed with one hand, so both hands must be used to open and close the blinds 200. During the process of operating with both hands, once the human body loses stability, an accident may occur, so the safety of the operator cannot be fully guaranteed.

[0046] In order to solve the above problems, Figure 3 and Figure 4As shown, this embodiment provides an auxiliary switch shutter device 100, which is used to assist in opening or closing the shutter 200 of the cargo warehouse. The auxiliary switch shutter device 100 includes a support rod 10, an auxiliary opening mechanism 20 and an auxiliary closing mechanism 30. The support rod 10 can abut against the handrail 230 and rotate relative to the handrail 230; the auxiliary opening mechanism 20 is arranged at one end of the support rod 10, and the auxiliary opening mechanism 20 can be plugged with the handle 2201. When the end of the support rod 10 close to the shutter body 210 rotates upward relative to the handrail 230, the auxiliary opening mechanism 20 opens the hatch cover 220; the auxiliary closing mechanism 30 is arranged at one end of the support rod 10, and the auxiliary closing mechanism 30 can be plugged with the handle 2201. When the end of the support rod 10 close to the shutter body 210 rotates downward relative to the handrail 230, the auxiliary closing mechanism 30 closes the hatch cover 220. When the shutter 200 needs to be opened, the operator holds one end of the support rod 10, makes the support rod 10 abut against the handrail 230, and makes the auxiliary opening mechanism 20 plug and match with the handle 2201, and rotates the support rod 10 with the handrail 230 as a fulcrum, so that the end of the support rod 10 close to the shutter body 210 rotates upward relative to the handrail 230. At this time, the ear buckle of the hatch cover 220 moves in the guide groove 2501 of the guide plate 250 until the ear buckle moves to the guide groove 2501. When the shutter 200 is in the hook groove area, the shutter 200 is opened; when the shutter 200 needs to be closed, the operator holds one end of the support rod 10, so that the support rod 10 abuts against the handrail 230, and the auxiliary closing mechanism 30 is plugged and matched with the handle 2201, and the handle 2201 is pushed upward to make the ear buckle of the hatch cover 220 disengage from the hook groove area of ​​the guide groove 2501, and the support rod 10 is pulled downward, and the auxiliary closing mechanism 30 pulls the handle 2201 to move downward, thereby completing the closing of the shutter 200. The auxiliary shutter device 100 assists the operator in opening and closing the shutter 200, saving manpower and improving the safety of the operator in opening or closing the shutter 200 at the hatch cover 220 position of the cargo hold of bulk carriers, container ships, etc.

[0047] Specifically, if Figure 3As shown, the auxiliary opening mechanism 20 includes two connectors 22 and a connecting assembly 21; the connecting assembly 21 is arranged at one end of the support rod 10, at least part of the connecting assembly 21 extends in a direction perpendicular to the axis of the support rod 10, and the two connectors 22 are arranged on the connecting assembly 21 at intervals in a direction perpendicular to the axis of the support rod 10. By arranging the two connectors at intervals in a direction perpendicular to the axis of the support rod 10, the stability of the support rod 10 when rotating relative to the handrail 230 can be improved, thereby facilitating better opening of the blinds 200. Among them, the connecting assembly 21 includes a connecting rod 211 and two connecting members 212, the connecting rod 211 is arranged at one end of the support rod 10 and extends in a direction perpendicular to the axis of the support rod 10; the two connecting members 212 are arranged on the connecting member 212 at intervals in a direction perpendicular to the axis of the support rod 10, and the connecting members 212 are arranged one by one with the connectors 22.

The handle 2201 can rotate relative to the first receiving groove 221. When the support component rotates relative to the handrail 230, the handle 2201 rotates in the first receiving groove 221, thereby facilitating the auxiliary opening of the shutter 200. In this embodiment, the first receiving groove 221 is arc-shaped, and in other embodiments, it can also be V-shaped.

[0049] Likewise, if Figure 3 As shown, the auxiliary closing mechanism 30 has a second receiving groove 31, and the second receiving groove 31 is used to accommodate the handle 2201. The handle 2201 can rotate relative to the second receiving groove 31.
