[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] As Figures 1-5 Indicated, the utility model adopts technical scheme as follows: a safety protection device of hydrogen flame detector, including shell 1, the top of shell 1 is slidably provided with connecting block 3. The end of connecting block 3 is rotatably connected with cover plate 2, and cover plate 2 is movably arranged at one side of the opening of shell 1. Cover plate 2 is positioned at one side of shell 1 by connecting block 3, so that cover plate 2 can rotate at one side of shell 1.

[0026] The two sides of the end of connecting block 3 extending into shell 1 are fixedly connected with protrusions, and the two protrusions are slidably connected to the inside of shell 1. The end of connecting block 3 away from the protrusions extends to the outside of shell 1. The end of connecting block 3 is positioned in shell 1 by the cooperation of the two protrusions, so that connecting block 3 avoids moving out of shell 1 when sliding.

[0027] The end of cover plate 2 away from connecting block 3 is fixedly connected with mounting plate 13, and mounting plate 13 is perpendicular to cover plate 2. Mounting plate 13 is slidably arranged at the bottom of shell 1. When connecting block 3 drives cover plate 2 to move, mounting plate 13 will slide at the bottom of shell 1. Shell 1 is provided with a positioning member for positioning mounting plate 13.

[0028] The positioning member comprises a first insertion hole 10 and a second insertion hole 11, both of which are arranged on the bottom surface of the shell 1 and close to one end of the cover plate 2. The mounting plate 13 is provided with a mounting hole 12, which is equal in size to the first insertion hole 10 and the second insertion hole 11, and is movably arranged at the bottom of the first insertion hole 10 and the second insertion hole 11. The mounting hole 12 is a bolt hole, which is convenient for fixing with bolts. When the mounting plate 13 slides on the bottom of the shell 1, the mounting hole 12 moves on the bottom of the first insertion hole 10 and the second insertion hole 11, so that the mounting hole 12 corresponds to the first insertion hole 10 and the second insertion hole 11.

[0029] The inside of the shell 1 is slidably connected with a sliding plate 7, one side of which is provided with a hydrogen flame detector.

[0030] A plurality of second springs 8 are uniformly and fixedly connected to one side of the sliding plate 7, and the other ends of the plurality of second springs 8 are fixedly connected to the inner wall of the shell 1.

[0031] Limiting plates 9 are fixedly connected to the four corners on the other side of the sliding plate 7, and the limiting plates 9 are L-shaped. The four limiting plates 9 are symmetric about the middle part of the sliding plate 7, and the hydrogen flame detector is movably arranged between the four limiting plates 9. The hydrogen flame detector is fixed on one side of the sliding plate 7 by the cooperation of the four limiting plates 9, and rubber pads are arranged on the side of the four limiting plates 9 close to the middle part of the sliding plate 7, so that the rubber pads contact the hydrogen flame detector, and the fixing effect of the hydrogen flame detector is better.

[0032] The cover plate 2 is provided with a fixing member for abutting against the hydrogen flame detector.

[0033] The fixing member comprises a sliding rod 4 which slidably penetrates the middle part of the cover plate 2. One end of the sliding rod 4 is fixedly connected with a pressing block 6, and a first spring 5 is fixedly connected between the pressing block 6 and the side surface of the cover plate 2, and the first spring 5 is sleeved on the sliding rod 4. When the cover plate 2 is rotated to one side of the shell 1, the pressing block 6 will be located inside the shell 1, so as to abut against one side of the hydrogen flame detector by the pressing block 6. Rubber pads are arranged on the side of the pressing block 6 away from the sliding rod 4, so that the rubber pads contact the hydrogen flame detector when the pressing block 6 abuts against the hydrogen flame detector, thereby avoiding damage to the hydrogen flame detector due to excessive abutting force.

[0034] The first spring 5 and the second spring 8 are both damping springs. The first spring 5 and the second spring 8 cooperate to have a damping protection effect on the hydrogen flame detector.

[0035] Working principle:

[0036] In use, the cover plate 2 is rotated upward, so that one end of the cover plate 2 is rotated on the connecting block 3, driving the sliding rod 4 and the pressing block 6 to move upward.

[0037] The hydrogen flame detector is moved to one side of the sliding plate 7 and is located between the four limiting plates 9.

[0038] The cover plate 2 is rotated downward, the pressing block 6 is moved downward, and the pressing block 6 is moved to the inside of the shell 1.

[0039] After the cover plate 2 is rotated to the vertical state, the connecting block 3 is pushed to the inside of the shell 1, the cover plate 2 is moved to the side close to the shell 1, the mounting plate 13 is moved to the bottom of the shell 1, and the pressing block 6 is close to the side of the hydrogen flame detector.

[0040] When the pressing block 6 contacts the hydrogen flame detector, the pressing block 6 is no longer moved. The cover plate 2 continues to move, the cover plate 2 slides on the sliding rod 4 and compresses the first spring 5, the first spring 5 has a pushing force on the pressing block 6, thereby making the pressing block 6 abut against the hydrogen flame detector. With the increase of the abutting force, the pressing block 6 pushes the hydrogen flame detector and the sliding plate 7 to move, so that the sliding plate 7 compresses the second spring 8. Then, the first spring 5 and the second spring 8 cooperate to have a damping effect on the hydrogen flame detector.

[0041] When the mounting plate 13 is moved to the bottom of the shell 1, the mounting hole 12 corresponds to the first insertion hole 10. The bolt is rotated into the mounting hole 12, the bolt extends into the first insertion hole 10, the mounting plate 13 is fixed, and then the cover plate 2 is fixed on one side of the shell 1. The cover plate 2 seals the hydrogen flame detector in the shell 1, and has a safety protection effect on the hydrogen flame detector.

[0042] When the hydrogen flame detector is needed, the bolt is rotated downward, the bolt is away from the first insertion hole 10, the cover plate 2 is slightly released, and the cover plate 2 is automatically pushed to move away from the shell 1 under the action of the first spring 5 and the second spring 8, the connecting block 3 is slid to the outside of the shell 1, and the mounting plate 13 is slid on the bottom of the shell 1.

[0043] Until the mounting hole 12 corresponds to the second insertion hole 11, the fixing effect of the pressing block 6 on the hydrogen flame detector is not affected. The bolt can be rotated into the second insertion hole 11 to fix the cover plate 2 again. Due to the movement of the cover plate 2, there is a gap between the cover plate 2 and the shell 1, a pipeline can pass through the gap to connect the hydrogen flame detector for use. Then, the position of the mounting hole 12 can be adjusted according to the use condition, and the practicability is good.

[0044] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
