For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0038] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0039] First, please refer to Figure 1 , Figure 1 The structure diagram of one embodiment of the operating device of the open rack type gasifier seawater tank plug of the utility model. As Figure 1 Indicated, the operating device of the open rack type gasifier seawater tank plug comprises an operating handle 3, a transmission assembly 4, a plug rod 5, a plug 6 and a guardrail 1. The above-mentioned guardrail 1 is installed to one side of the seawater tank 2 close to the discharge port, and the above-mentioned transmission assembly 4 is installed to the guardrail 1.

[0040] In the working state, with the rotation of the operating handle 3, the plug rod 5 can drive the plug 6 to move towards or away from the discharge port through the transmission assembly 4, so that the plug 6 is inserted into or pulled out of the discharge port.

[0041] Please refer to Figures 2 to 5 , Figure 2 The structure diagram of one embodiment of the operating device in the plug-pulled-out state of the utility model; Figure 3 The structure diagram of one embodiment of the operating device when operating the operating handle of the utility model;Figure 4 It is another embodiment structure diagram of the operating handle of the utility model for operating the device; Figure 5 It is another embodiment structure diagram of the operating handle of the utility model for operating the device; Figures 2 to 5 As shown in the figure, the transmission assembly 4 can include a first connecting pin 41, a second connecting pin 42, a third connecting pin 43, a fixed part 44, and two symmetrical movable rods 45. The fixed part 44 can be L-shaped, with a vertical section fixedly connected to the guardrail 1 by a bolt, and the lower ends of the two movable rods 45 are pivotally connected to the horizontal section of the fixed part 44 by the first connecting pin 41. The upper end of the plug rod 5 is slidably inserted through the horizontal section of the fixed part 44 and between the two movable rods 45 in the vertical direction.

[0042] The operating handle 3 includes a handle 31 and two symmetrical L-shaped operating rods 32, the open end of the L-shaped operating rod 32 (the right end in the figure) away from the plug rod 5 is fixedly connected to the handle 31, and the upper end of the two movable rods 45 is pivotally connected to the corner of the L-shaped operating rod 32 by the second connecting pin 42. The upper end of the L-shaped operating rod 32 (the upper end in the figure) close to the open end of the plug rod 5 is pivotally connected to the top end of the plug rod 5 by the third connecting pin 43. Figure 2 Figure 2

[0043] Please refer to the order of Figures 2 to 5 to switch from the plug-out state to the plug-in state, and the working principle of the operating device will be explained. With counterclockwise operation of the handle 31, the L-shaped operating rod 32 rotates around the second connecting pin 42, and the plug rod 5 is subjected to a downward force from the L-shaped operating rod 32 and slides downward. Since the plug rod 5 slides in the vertical direction, the lower end of the two movable rods 45 rotates around the first connecting pin 41, and the L-shaped operating rod 32 rotates around the third connecting pin 43 relative to the plug rod 5.

[0044] Until the plug rod 5 is lowered to the point where the plug is inserted into the discharge port, the plug-in state is entered, and the rotation of the handle 31 is stopped, and the switching is completed.

[0045] In order to limit the sliding direction of the plug rod 5, a limiting sleeve 46 can be provided on the horizontal section of the fixed part 44. The limiting sleeve 46 is provided with a through hole, the size of the through hole is matched with the size of the plug rod 5, and the plug rod 5 can be slidably inserted into the through hole. The upper end of the limiting sleeve 46 is clamped to the upper end of the horizontal section of the fixed part 44, and the lower end passes through the fixed part 44. The lower end of the movable rod 45 can be pivotally connected to the upper end of the fixed part 44 by the first connecting pin 41.

[0046] ​​The lower end of the limiting sleeve 46 can be provided with external thread 461, and the limiting sleeve can be fixed to the fixing member 44 by means of the nut 462 cooperating with the external thread 461. In this way, the limiting sleeve 46 can limit the sliding direction of the plug rod 5, thereby improving the reliability of the operating device.

[0047] The limiting sleeve 46 can also be replaced by a linear bearing, which can be selected by those skilled in the art according to the actual situation.

[0048] In order to limit the rotation angle of the handle 31, a limiting plate 47 is connected between the two movable rods 45. When entering the plug-out state, the L-shaped operating rod 32 engages with the limiting plate 47, which serves as a prompt to the operator that the plug-out state has been entered, and also avoids excessive rotation, which can damage the related parts.

[0049] Similarly, the vertical section of the fixing member 44 can also serve as a limiting function. When entering the plug-in state, the L-shaped operating rod 32 engages with the vertical section of the fixing member 44, which serves as a prompt to the operator that the plug-in state has been entered, and also avoids excessive rotation, which can damage the related parts.

[0050] Further, in order to make the entering of the plug-out state and the plug-in state more obvious, the rotation range of the handle 31 can be adjusted to 180°, i.e. in the plug-out state, the handle 31 is horizontally rotated to the right (the direction in Figure 2 ), and in the plug-in state, the handle 31 is horizontally rotated to the left (the direction in Figure 5 ).

[0051] A screw rod 51 can also be provided between the plug rod 5 and the plug 6, and the two ends of the screw rod 51 are threadedly connected with the bottom of the plug rod 5 and the top end of the plug 6, thereby facilitating the replacement of the plug 6 and improving the convenience of maintenance.

[0052] The device drives the plug rod 5 to slide in the vertical direction by rotating the handle 31, so that the plug 6 is plugged into or pulled out of the discharge port, without the need for the operator to climb onto the fin 7 to insert or pull out the plug 6, thereby improving the safety and convenience of operation and improving the efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
