DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-9 This application is described in further detail.

[0026] The present application embodiment discloses a switch device for an inspection hole of an ash discharge valve, referring to Figure 1-Figure 3 In this embodiment, the switch device includes a bottom plate 2, a panel 3, a hinge mechanism and a locking mechanism. The bottom plate 2 is fixedly mounted on the ash discharge valve inspection hole 1. The bottom plate 2 is a rectangular structure with a size of 360mm*130mm and a thickness of 8mm. An ash discharge communication hole 21 is opened in the middle of the bottom plate 2. The size of the ash discharge communication hole 21 is 70mm*230mm, and the ash discharge communication hole 21 is connected to the port of the ash discharge valve inspection hole 1.

[0027] At the same time, refer to Figure 2 and Figure 4 In this embodiment, the panel 3 is rotatably mounted on one side of the base plate 2 through a hinge mechanism. The panel 3 is a rectangular structure with a size of 360mm*130mm and a thickness of 15mm. The panel 3 and the base plate 2 can be connected to each other through the setting of the hinge mechanism, so that the panel 3 can be more flexibly covered on the base plate 2 in the future, thereby achieving the effect of quick opening and closing.

[0028] In addition, a handle 31 is installed on the front side of the panel 3, and the panel 3 can be easily moved through the handle 31, so that the panel 3 can be controlled to cover the dust removal connecting hole 21 on the base plate 2, and the panel 3 can also be removed from the base plate 2.

[0029] There are two locking mechanisms, which are symmetrically installed on the two ends of the bottom plate 2 away from the panel 3, so as to fasten the panel 3 to the bottom plate 2, thereby tightly sealing the ash discharge valve inspection hole 1 to prevent the ash inside the ash discharge valve from leaking out of the ash discharge valve inspection hole 1, thereby reducing environmental pollution and protecting the occupational health and safety of workers.

[0030] Better, refer to Figure 3 and Figure 4 In this embodiment, a boss 32 is further installed on the rear side of the panel 3, and the boss 32 cooperates with the dust removal connecting hole 21; when the panel 3 is covered on the base plate 2, the matching clearance between the boss 32 on the panel 3 and the dust removal connecting hole 21 of the base plate 2 is within 0.5mm, thereby making the sealing performance between the panel 3 and the base plate 2 better.

[0031] The structures of the hinge mechanism and the locking mechanism are described in detail below:

[0032] Specifically, refer to Figure 2 and Figure 5 In this embodiment, the hinge mechanism includes a first hinge piece 22, a second hinge piece 33 and a connecting assembly. There are two first hinge pieces 22, which are symmetrically mounted on the bottom side of the rear portion of the bottom plate 2, and both of the first hinge pieces 22 are rectangular structures; there are two second hinge pieces 33, which are symmetrically mounted on the bottom side of the front portion of the panel 3, and both of the second hinge pieces 33 are rectangular structures, and the two second hinge pieces 33 correspond to the two first hinge pieces 22 and have the same size; the connecting assembly is arranged between the two first hinge pieces 22 and the two second hinge pieces 33, so as to connect the panel 3 to the bottom plate 2.

[0033] More specifically, refer to Figure 2 , Figure 7 and Figure 8 In this embodiment, the connecting assembly includes a first connecting rod 23, a second connecting rod 34 and a third hinge piece 4. The two first hinge pieces 22 are each provided with a first hinge hole 221, and the two ends of the first connecting rod 23 are respectively rotatably mounted between the two first hinge holes 221; the two second hinge pieces 33 are each provided with a second hinge hole 331, and the two ends of the second connecting rod 34 are respectively rotatably connected between the two second hinge holes 331, and the first connecting rod 23 and the second connecting rod 34 are of the same shape and size.

[0034] Two third hinge pieces 4 are provided, both of which are L-shaped structures, and both ends of the two third hinge pieces 4 are provided with third hinge holes 41, and both ends of the two third hinge pieces 4 are symmetrically fixedly sleeved between the first connecting rod 23 and the second connecting rod 34 through the third hinge holes 41, so as to connect the first connecting rod 23 and the second connecting rod 34 to each other, thereby connecting the panel 3 and the bottom plate 2 to each other, thereby making the switch device of the present application more flexible to achieve the effect of quick opening and closing.

[0035] At the same time, refer to Figure 3 and Fig. 9 In this embodiment, the locking mechanism includes a screw hinge piece 5, a rotating shaft 51, a pin 52, a movable ring screw 53 and a ring screw 54. There are two screw hinge pieces 5, both of which are square structures, and both of which are symmetrically installed on one side of the rear part of the bottom plate 2; both ends of the rotating shaft 51 are rotatably installed between the two screw hinge pieces 5; one end of the pin 52 is fixedly connected to the middle of the shaft body of the rotating shaft 51, and the pin 52 and the rotating shaft 51 are perpendicular to each other.

[0036] One end of the movable ring screw 53 is fixedly connected to the end of the pin 52 away from the rotating shaft 51, and the movable ring screw 53 and the pin 52 are in the same straight line; and movable grooves 6 are opened on both sides of the base plate 2 and the panel 3. When the base plate 2 and the panel 3 abut against each other, the movable grooves 6 on both sides of the base plate 2 respectively correspond to the movable grooves 6 on both sides of the panel 3 and are connected to each other, and these movable grooves 6 are U-shaped structure notches, so that the two interconnected movable grooves 6 cooperate with the movable ring screw 53 at the same time; by swinging the movable ring screw 53, under the action of the pin 52 and the rotating shaft 51, the movable ring screw 53 swings into the movable groove 6.

[0037] At the same time, the annular screw 54 is threadedly connected to the movable ring screw 53, so that the annular screw 54 can be screwed into the movable ring screw 53, and the diameter of the annular screw 54 is larger than the width of the movable groove 6. When the panel 3 is abutted against the base plate 2, the movable ring screw 53 is swung into the movable groove 6, and then the annular screw 54 is screwed so that the annular screw 54 is pressed tightly against the panel 3, so that the panel 3 can be fastened to the base plate 2.

[0038] Preferably, a movable ring 55 is further installed on the outer side wall of the ring screw 54 . The movable ring 55 can be arranged to more conveniently drive the ring screw 54 to rotate, so that the ring screw 54 is more firmly pressed against the panel 3 .

[0039] Secondly, refer to Figure 4 and Figure 5In order to improve the sealing between the panel 3 and the bottom plate 2, in the present embodiment, a sealing groove 24 is further provided at the front of the bottom plate 2, and a packing sealing strip 25 is installed in the sealing groove 24. The packing sealing strip 25 is arranged around the outer side of the dust removal connecting hole 21 of the bottom plate 2, and the packing sealing strip 25 is mainly woven from relatively soft linear objects. These linear objects can be rubber or plastic of various hardnesses, and the strips with a square cross-sectional area are filled in the sealing groove 24, thereby achieving a sealing effect.

[0040] When the panel 3 is pressed against the base plate 2, the packing sealing strip 25 and one side of the panel 3 are pressed against each other, and the compression of the packing sealing strip 25 is fully utilized to achieve better sealing performance, thereby making the panel 3 and the base plate 2 tighter, thereby preventing the ash in the ash discharge valve inspection hole 1 from leaking out from the gap between the panel 3 and the base plate 2.
