[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the staff can install and take the electric heater by rotating the two protective shells, and by rotating the rotating plate to make the rotating plate cooperate with the fixed plate to clamp the protective shell, which can play a good role in fixing the position of the fixed plate. The mounting plate and a plurality of heating tubes can press down the inner bottom ends of the two protective shells in real time by their own weight, so that the opposite surfaces of the two protective shells are squeezed against each other. When in use, the two protective shells cooperate with each other, which can play a good storage and protection role for the mounting plate and the plurality of heating tubes. At the same time, when the two protective shells rotate, the detection disk can be automatically driven to move. When the positions of the two protective shells and the heating tubes are fixed, the detection disk is automatically connected to the connecting blocks on the mounting plate, which is more convenient to use and does not require the staff to manually power on the electric heater.

[0018] 2. The two elastic temperature monitoring plates inside the two protective shells in the present invention cooperate with each other, which can better clamp and fix the middle ends of several heating tubes, and can improve the stability of the heating tubes during use. At the same time, the elastic temperature monitoring plate can continuously push the heating tube through its own elasticity, so that the side of the elastic temperature monitoring plate is in real time contact with the outer wall of the heating tube. When in use, because the elastic temperature monitoring plate is in real time contact with the outer walls of several heating tubes, the staff can monitor and compare the surface temperatures of several heating tubes through the two elastic temperature monitoring plates during use, so as to prevent the occurrence of uneven surface temperatures of several heating tubes or unstable connection between the heating tubes and the connecting blocks, resulting in the heating tubes being unable to heat.

[0019] 3. In the present invention, when the two protective shells are conveniently rotated toward opposite surfaces, the detection disk can push the mounting plate and a plurality of heating tubes to move in the direction of the mounting shell. When in use, the detection disk and the inner walls of the two protective grooves cooperate with each other, which can play a better clamping role on the mounting plate, making the mounting plate more stable during use, and preventing the mounting plate and the heating tubes thereon from sliding during use. When the staff takes the heating tubes inside the protective shell, the protective shell can pull the detection disk through the movable plate to move the detection disk away from the mounting plate. The clamping of the mounting plate can be disconnected during use, which is convenient for the staff to take the mounting plate and the heating tubes. At the same time, when the two protective shells rotate, the connecting piece on the detection disk can automatically disconnect the electrical connection with the connecting block on the mounting plate, making it safer for the staff to take the mounting plate and the heating tubes.

[0020] 4. In the present invention, when the staff detects the heating tube, the staff can connect the external detection connecting wire with the connecting head, so that the detection connecting wire can energize several heating tubes through the connecting head, the connecting piece and the connecting block, so that the several heating tubes heat their surfaces and the surrounding air, and the elastic temperature monitoring board and the several temperature sensors on the connecting board can respectively detect the surface temperature of the heating tube and the air temperature inside the two protective shells. When in use, the heating efficiency of the heating tube on its surface and the heating uniformity of the several heating tubes can be detected. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] As a technical optimization scheme of the present invention, a mounting plate 8 is installed at one end of the two protective shells 2 close to the detection disk 4, and the two ends of the mounting plate 8 are respectively located inside the two protective grooves 13.

The top of the base 1 is located below the two protective shells 2 and is provided with through holes 29 in the length direction. A lifting plate 30 is slidably installed inside the through hole 29. The lifting plate 30 is located below the protective shell 2 and away from the side of the rotating block 20. Arc chamfers are provided on both sides of the top of the lifting plate 30.

[0039] As a technical optimization solution of the present invention, a mounting shell 7 is installed at one end of the interior of a protective shell 2 away from the detection disk 4, and a support tube 24 is installed at the middle end of the side of the mounting shell 7 close to the protective groove 13. The edge position of the end of the support tube 24 away from the mounting shell 7 is provided with an arc chamfer, and the interior of the support tube 24 is interconnected with the interior of the mounting shell 7; when in use, the support tube 24 can play a better supporting and position limiting role for the end of several heating tubes 12 close to the mounting shell 7.

[0040] As a technical optimization scheme of the present invention, a mounting frame 25 is installed on the end of the inner wall of the mounting shell 7 away from the support tube 24, and an electric shaft 26 is rotatably installed on the side of the mounting frame 25 close to the support tube 24. A mounting sleeve 27 is installed on the outer wall of the electric shaft 26, and a plurality of fan blades 28 are installed on the outer wall of the mounting sleeve 27. The inner wall of the mounting shell 7 close to the support tube 24 is funnel-shaped, and the end of the support tube 24 away from the mounting shell 7 is located between the plurality of heating tubes 12; the electric shaft 26 drives the plurality of fan blades 28 to rotate, and when the staff needs to take the heating tube 12 inside the protective shell 2, the fan blades 28 can quickly dissipate the heat inside the protective shell 2 and on the surface of the heating tube 12.

[0041] As a technical optimization solution of the present invention, a clamping plate 21 is installed at the middle end of the outer wall of the fixed plate 15 in the length direction. The end of the clamping plate 21 away from the fixed plate 15 passes through the mounting hole 6, and a rotating plate 22 is rotatably installed. Both ends of the rotating plate 22 are abutted against the outer wall of the protective shell 2. A plurality of temperature detection units are provided inside the elastic temperature monitoring plate 17. When in use, the elastic temperature monitoring plate 17 can monitor the surface temperature of the heating tube 12 in real time, and can also clamp and limit the position of the middle ends of several heating tubes 12.

[0042] As a technical optimization solution of the present invention, trapezoidal limit blocks 3 are installed on both sides of the top of the base 1, the limit blocks 3 are located below the side of the protective shell 2, and support plates 32 are installed at the bottom of the base 1 near the corners; when the staff takes the heating tube 12 inside the protective shell 2, the limit blocks 3 can provide better support for the protective shell 2 and limit the rotation angle of the protective shell 2.

[0043] As a technical optimization scheme of the present invention, the mounting plate 8 is located between the inner wall of the end of the protective groove 13 away from the limiting plate 5 and the detection disk 4, the side of the elastic temperature monitoring plate 17 away from the fixing plate 15 is in contact with the heating tube 12, and a plurality of screw holes 10 are provided on the side of the mounting plate 8 near the edge; when the staff inspects the heating tube 12, the interior of the protective groove 13 cooperates with the detection disk 4 to clamp and fix the mounting plate 8 in position.

[0044] When the present invention is used, the staff first installs the two fixing plates 15 inside the fixing grooves 14 on the inner walls of the two protective shells 2, respectively. When in use, the card plate 21 located on the side of the fixing plate 15 passes through the mounting hole 6, and the mounting hole 6 can play a better position limiting role for the fixing plate 15 through the card plate 21. When the staff has installed the fixing plate 15, and the end of the card plate 21 away from the fixing plate 15 passes through the mounting hole 6, the staff can rotate the rotating plate 22 so that the two ends of the rotating plate 22 are respectively located on both sides of the mounting hole 6, and at the same time, the side of the rotating plate 22 abuts against the outer wall of the protective shell 2. When in use, the rotating plate 22 cooperates with the fixing plate 15 to clamp the protective shell 2, which can play a better position fixing role for the fixing plate 15. The staff places the mounting plate 8 to be tested and the several heating tubes 12 thereon between the two protective shells 2 from above. When in use, the bottom end of the mounting plate 8 abuts against the inner bottom ends of the two protective shells 2, and the two ends of the mounting plate 8 are respectively located inside the protective grooves 13 on the inner walls of the two sides of the two protective shells 2.

[0045] When the staff has placed the mounting plate 8 and the heating tube 12, the staff can pull down the lifting plate 30 through the hydraulic cylinder 33, so that the top of the lifting plate 30 moves down to the inside of the through hole 29, and the protective shell 2 can press down the bottom end of the inside of the protective shell 2 through the mounting plate 8 and the heating tube 12, so that the top end of the protective shell 2 rotates toward the direction close to the heating tube 12 with the rotating block 20 as the center until the opposite surfaces of the two protective shells 2 abut against each other. When in use, the mounting plate 8 and the plurality of heating tubes 12 can press down the inner bottom ends of the two protective shells 2 in real time by their own weight, so that the opposite surfaces of the two protective shells 2 are squeezed against each other. When in use, the two protective shells 2 cooperate with each other, which can better fix and protect the mounting plate 8 and the plurality of heating tubes 12.

[0046] When the protective shell 2 rotates toward the direction of the heating tube 12, the protective shell 2 can drive the fixing plate 15 on its inner wall to rotate toward the direction of the heating tube 12 until the elastic temperature monitoring plate 17 located on the inner wall of the fixing plate 15 is away from the side of the fixing plate 15 and abuts against the outer wall of the heating tube 12. When in use, the two elastic temperature monitoring plates 17 located inside the two protective shells 2 cooperate with each other to better clamp and fix the middle ends of several heating tubes 12, which can improve the stability of the heating tube 12 when in use. At the same time, the elastic temperature monitoring plate 17 can continuously push the heating tube 12 through its own elasticity. , so that the side of the elastic temperature monitoring plate 17 is in real time contact with the outer wall of the heating tube 12. Because a plurality of temperature detection units are installed inside the elastic temperature monitoring plate 17, the plurality of temperature detection units can monitor the surface temperature of the heating tube 12 through the side of the elastic temperature monitoring plate 17 when in use. When in use, because the elastic temperature monitoring plate 17 is in contact with the outer walls of a plurality of heating tubes 12 at the same time, the staff can monitor and compare the surface temperatures of a plurality of heating tubes 12 through two elastic temperature monitoring plates 17 when in use, so as to prevent the situation where the surface temperatures of the plurality of heating tubes 12 are uneven.

[0047] When the two protective shells 2 are conveniently rotated toward the opposite sides, the inner walls of the two protective shells 2 can push the moving plate 19 through the fixed block 18, and the end of the moving plate 19 away from the fixed block 18 will push the detection plate 4 to move in the direction of the mounting plate 8 as the protective shell 2 moves. When the detection plate 4 moves, it can push the mounting plate 8 and a plurality of heating tubes 12 to move in the direction of the mounting shell 7 until the edge of the mounting plate 8 away from the detection plate 4 abuts against the inner walls of the two protective grooves 13 respectively. When in use, the detection plate 4 and the inner walls of the two protective grooves 13 cooperate with each other, which can play a better clamping role on the mounting plate 8, making the mounting plate 8 more stable when in use, and preventing the mounting plate 8 and the heating tubes 12 thereon from sliding when in use.

[0048] When in use, several connecting pieces 31 located on the side of the detection disk 4 are connected to several connecting blocks 9 on the mounting plate 8. At the same time, when the mounting plate 8 and the several heating tubes 12 move, the ends of the several heating tubes 12 away from the mounting plate 8 can be sleeved on the support tube 24. When in use, the support tube 24 can limit the position and support the ends of the several heating tubes 12 away from the mounting plate 8. The support tube 24, the detection disk 4 and the elastic temperature monitoring plate 17 can respectively support and limit the position of the two ends and the middle end of the heating tube 12.

[0049] When the staff is testing the heating tube 12, the staff can connect the external detection connecting line with the connecting head 34, so that the detection connecting line can energize the several heating tubes 12 through the connecting head 34, the connecting piece 31 and the connecting block 9, so that the several heating tubes 12 heat their surfaces and the surrounding air, and the several temperature sensors 23 on the elastic temperature monitoring plate 17 and the connecting plate 16 can respectively detect the surface temperature of the heating tube 12 and the air temperature inside the two protective shells 2. When in use, the heating efficiency of the heating tube 12 on its surface and the heating uniformity of the several heating tubes 12 can be detected. When in use, the situation that the heating tube 12 cannot be used for heating due to connection problems can also be detected.

[0050] When the staff has finished inspecting the heating tube 12, the staff can drive the plurality of fan blades 28 to rotate through the electric rotating shaft 26. When the fan blades 28 rotate, the outside air enters between the plurality of heating tubes 12 through the supporting tube 24, and flows to the inside of the protective shell 2 through the gaps between the plurality of heating tubes 12. When in use, the surface of the heating tube 12 and the air temperature inside the protective shell 2 can be cooled down. The high-temperature air inside the two protective shells 2 can also flow to the outside through the supporting tube 24 through the rotation of the fan blades 28. Before the staff takes the heating tube 12, the surface of the heating tube 12 and the air inside the protective shell 2 can be cooled down in advance to prevent the high-temperature air inside the protective shell 2 and the high temperature on the surface of the heating tube 12 from causing harm to the staff when the two protective shells 2 are opened and the heating tube 12 is taken.

[0051] The staff can push the lifting plate 30 through the hydraulic cylinder 33, and the lifting plate 30 pushes the protective shell 2, so that the protective shell 2 rotates in the direction away from the opposite surface with the rotating block 20 as the center, until the outer wall of the protective shell 2 and the limit block 3 abut each other. When in use, the limit block 3 can limit the rotation angle of the protective shell 2, and the staff can take the mounting plate 8 and the heating tube 12 inside the two protective shells 2. When the two protective shells 2 rotate in the direction away from the opposite surface, the protective shell 2 can pull the detection disk 4 through the moving plate 19, so that the detection disk 4 moves in the direction away from the mounting plate 8. When in use, the clamping of the mounting plate 8 can be disconnected, which is convenient for the staff to take the mounting plate 8 and the heating tube 12. At the same time, when the two protective shells 2 rotate, the connecting piece 31 on the detection disk 4 can automatically disconnect the electrical connection with the connecting block 9 on the mounting plate 8, so that the staff can take the mounting plate 8 and the heating tube 12 more safely.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
