[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the staff can install and take the electric heater by rotating the two protective shells, and make the rotating plate cooperate with the fixed plate by rotating the rotating 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 end of the two protective shells in real time through their own weights, so that the opposite surfaces of the two protective shells are mutually extruded. When in use, the two protective shells cooperate with each other, which can play a good role in storing and protecting the mounting plate and a 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 connection block 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. In the present invention, the two elastic temperature monitoring plates inside the two protective shells cooperate with each other, which can play a good role in clamping and fixing the middle ends of a plurality of 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 contact with the outer wall of the heating tube in real time. Because the elastic temperature monitoring plate is in contact with the outer walls of a plurality of heating tubes at the same time during use, the staff can monitor and compare the surface temperatures of a plurality of heating tubes through the two elastic temperature monitoring plates during use, preventing the situation that the surface temperatures of a plurality of heating tubes are uneven or the connection between the heating tube and the connection block is unstable, resulting in the heating tube being unable to heat.

[0019] 3. When the two protective shells rotate towards the opposite side in the present invention, the detection disc can push the mounting plate and several heating tubes towards the direction of the mounting shell. During use, the detection disc and the inner walls of the two protective grooves cooperate with each other, which can play a good 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 disc through the moving plate, making the detection disc move away from the mounting plate. During use, the clamping of the mounting plate can be disconnected, facilitating 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 disc 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. When the staff detects the heating tubes in the present invention, the staff can connect the external detection connection line with the connector, so that the detection connection line can energize several heating tubes through the connector, the connecting piece and the connecting block, and several heating tubes can heat their surfaces and the surrounding air. The elastic temperature monitoring plate and several temperature sensors on the connecting plate can respectively detect the surface temperature of the heating tubes and the air temperature inside the two protective shells. During use, the heating efficiency of the heating tubes on their surfaces and the heating uniformity of several heating tubes can be detected. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Refer to Figures 1-10, An energy-saving explosion-proof electric heater detection device, including a base 1. On both sides of the top of the base 1, protective shells 2 are rotatably installed. The opposite surfaces of the two protective shells 2 are in contact with each other. Arc-shaped fixing grooves 14 are opened on the inner walls of the two protective shells 2. Installation holes 6 are opened on the inner wall of the fixing groove 14 in the length direction. An arc-shaped fixing plate 15 is installed inside the fixing groove 14. A connecting plate 16 is installed on the side of the fixing plate 15. On the side of the connecting plate 16 away from the inner wall of the fixing plate 15, a number of temperature sensors 23 are installed. An elastic temperature monitoring plate 17 is installed on the inner wall of the fixing plate 15. Both ends of the elastic temperature monitoring plate 17 are installed on the inner wall of the fixing plate 15. The middle end of the connecting plate 16 is located between the elastic temperature monitoring plate 17 and the inner wall of the fixing plate 15. At the same end of the inner walls of the two protective shells 2, mutually matching protective grooves 13 are opened. A detection disk 4 is installed inside the two protective shells 2. Both ends of the detection disk 4 are respectively movably installed inside the two protective grooves 13.

[0035] As a technical optimization scheme of the present invention, limit plates 5 are installed at one end of the two protective shells 2 close to the detection disk 4. Grooves 35 are opened at both ends of the detection disk 4. Moving plates 19 are rotatably installed on the inner walls of the grooves 35. At one end of the two moving plates 19 away from the detection disk 4, fixing blocks 18 are rotatably installed. The two fixing blocks 18 are respectively installed at one end of the inner walls of the two protective grooves 13 close to the limit plates 5; when the staff pushes the two protective shells 2 so that the opposite surfaces of the two protective shells 2 are in contact with each other, the detection disk 4 can be automatically pushed in the direction of the mounting plate 8 through the moving plates 19.

[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. Both ends of the mounting plate 8 are respectively located inside the two protective grooves 13. A number of U-shaped heating tubes 12 are installed on the side of the mounting plate 8 away from the detection disk 4. A number of connecting blocks 9 connected to both ends of the heating tubes 12 are installed on the side of the mounting plate 8 close to the detection disk 4. A number of connecting pieces 31 matching the connecting blocks 9 are installed on the side of the detection disk 4 close to the mounting plate 8. A connecting head 34 is installed on the side of the detection disk 4 away from the connecting piece 31; during use, the connecting pieces 31 on the detection disk 4 are electrically connected to the connecting blocks 9 on the mounting plate 8, which is convenient for the staff to energize the heating tubes 12.

[0037] As a technical optimization solution of the present invention, rotating blocks 20 are rotatably installed on the bottom ends of the two protective shells 2 on the sides far from the opposite surfaces. The bottom ends of the rotating blocks 20 are installed on the top of the base 1. Through holes 29 are formed in the top of the base 1 below the two protective shells 2 in the length direction. A lifting plate 30 is slidably installed inside the through holes 29. The lifting plate 30 is located on the side far from the rotating block 20 below the protective shell 2. Arc-shaped chamfers are provided on both sides of the top of the lifting plate 30. When in use, the lifting plate 30 can push the protective shell 2 to rotate, facilitating the installation and removal of the mounting plate 8 and the heating tube 12 by the staff.

[0038] As a technical optimization solution of the present invention, a U-shaped fixing frame 11 is installed in the middle of the bottom of the base 1. Hydraulic cylinders 33 are installed at the positions near the corners on both sides of the bottom of the fixing frame 11. The piston rod tops of the hydraulic cylinders 33 penetrate to the inside of the fixing frame 11, and the piston rod tops of the hydraulic cylinders 33 on both sides of the bottom of the fixing frame 11 are respectively installed at the bottoms of the two lifting plates 30. When in use, the hydraulic cylinders 33 can push the protective shell 2 to rotate through the lifting plates 30.

[0039] As a technical optimization solution of the present invention, a mounting shell 7 is installed at one end of the inside of one of the protective shells 2 far from the detection disc 4. A support tube 24 is installed in the middle of the side of the mounting shell 7 close to the protective groove 13. An arc-shaped chamfer is provided at the edge position of the end of the support tube 24 far from the mounting shell 7. The inside of the support tube 24 is in communication with the inside of the mounting shell 7. When in use, the support tube 24 can play a good role in supporting and position-limiting the ends of several heating tubes 12 close to the mounting shell 7.

[0040] As a technical optimization solution of the present invention, a mounting frame 25 is installed at one end of the inner wall of the mounting shell 7 far from the support tube 24. An electric rotating 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 rotating shaft 26. Several 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 in a funnel shape. The end of the support tube 24 far from the mounting shell 7 is located between several heating tubes 12. The electric rotating shaft 26 drives several fan blades 28 to rotate. When the staff needs to take out the heating tubes 12 inside the protective shell 2, the fan blades 28 can quickly dissipate the heat on the surface of the inside of the protective shell 2 and the heating tubes 12.

[0041] As a technical optimization solution of the present invention, a clamping plate 21 is installed in the middle of the outer wall of the fixing plate 15 along the length direction. One end of the clamping plate 21 away from the fixing plate 15 penetrates through the mounting hole 6, and a rotating plate 22 is rotatably installed. Both ends of the rotating plate 22 are in contact with the outer wall of the protective shell 2. A plurality of temperature detection units are arranged 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 at the same time can clamp and position the middle ends of a plurality of heating tubes 12.

[0042] As a technical optimization solution of the present invention, trapezoidal limiting blocks 3 are installed on both sides of the top of the base 1. The limiting blocks 3 are located below the side surface of the protective shell 2. Support plates 32 are installed at the positions close to the corners at the bottom of the base 1. When the staff takes out the heating tube 12 inside the protective shell 2, the limiting blocks 3 can play a good supporting role for the protective shell 2, and at the same time can limit the rotation angle of the protective shell 2.

[0043] As a technical optimization solution of the present invention, the mounting plate 8 is located between the inner wall of the protective groove 13 away from the limiting plate 5 and the detection disc 4. One side of the elastic temperature monitoring plate 17 away from the fixing plate 15 is in contact with the heating tube 12. A plurality of screw holes 10 are opened at the position close to the edge on the side surface of the mounting plate 8. When the staff detects the heating tube 12, the inside of the protective groove 13 cooperates with the detection disc 4 to clamp and fix the mounting plate 8.

[0044] When the present invention is in use, the staff first installs the two fixing plates 15 into the fixing grooves 14 on the inner walls of the two protective shells 2 respectively. During use, the clamping plate 21 on the side of the fixing plate 15 penetrates through the mounting hole 6, and the mounting hole 6 can play a good position limiting role for the fixing plate 15 through the clamping plate 21. When the staff finishes installing the fixing plate 15 and one end of the clamping plate 21 away from the fixing plate 15 penetrates through the mounting hole 6, the staff can rotate the rotating plate 22 so that both ends of the rotating plate 22 are located on both sides of the mounting hole 6 respectively. At the same time, the side surface of the rotating plate 22 is in contact with the outer wall of the protective shell 2. During use, the rotating plate 22 and the fixing plate 15 cooperate with each other to clamp the protective shell 2 and can play a good position fixing role for the fixing plate 15. The staff places the mounting plate 8 to be detected and a plurality of heating tubes 12 thereon between the two protective shells 2 from above. During use, the bottom end of the mounting plate 8 is in contact with the inner bottom ends of the two protective shells 2, and both ends of the mounting plate 8 are respectively located inside the protective grooves 13 on the inner walls on both sides of the two protective shells 2.

[0045] After the staff have placed the mounting plate 8 and the heating tubes 12, the staff can lower the lifting plate 30 by means of the hydraulic cylinder 33, so that the top end of the lifting plate 30 moves down into the through hole 29. Then, the protective housing 2 can be rotated towards the heating tube 12 with the rotating block 20 as the center by the downward pressure of the mounting plate 8 and the heating tubes 12 on the inner bottom end of the protective housing 2 until the opposite faces of the two protective housings 2 are in contact with each other. During use, the mounting plate 8 and several heating tubes 12 can press down on the inner bottom ends of the two protective housings 2 in real time by their own weights, causing the opposite faces of the two protective housings 2 to be squeezed against each other. During use, the two protective housings 2 cooperate with each other to play a good role in fixing and protecting the mounting plate 8 and several heating tubes 12.

[0046] When the protective housing 2 rotates towards the heating tube 12, the protective housing 2 can drive the fixing plate 15 on its inner wall to rotate towards the heating tube 12 until the side of the elastic temperature monitoring plate 17 on the inner wall of the fixing plate 15 away from the fixing plate 15 is in contact with the outer wall of the heating tube 12. During use, the two elastic temperature monitoring plates 17 inside the two protective housings 2 cooperate with each other to play a good role in clamping and fixing the middle parts of several heating tubes 12, improving the stability of the heating tubes 12 during 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 always in contact with the outer wall of the heating tube 12. Since several temperature detection units are installed inside the elastic temperature monitoring plate 17, several temperature detection units can monitor the surface temperature of the heating tube 12 through the side surface of the elastic temperature monitoring plate 17 during use. During use, because the elastic temperature monitoring plate 17 is in contact with the outer walls of several heating tubes 12 at the same time, the staff can monitor and compare the surface temperatures of several heating tubes 12 through the two elastic temperature monitoring plates 17 during use to prevent the situation of uneven surface temperatures of several heating tubes 12.

[0047] When the two protective housings 2 rotate towards each other, the inner walls of the two protective housings 2 can push the moving plate 19 through the fixing blocks 18, and the end of the moving plate 19 away from the fixing block 18 will push the detection disc 4 towards the mounting plate 8 as the protective housing 2 moves. When the detection disc 4 moves, it can push the mounting plate 8 and several heating tubes 12 towards the mounting shell 7 until the edge positions of the side of the mounting plate 8 away from the detection disc 4 are in contact with the inner walls of the two protective grooves 13 respectively. During use, the detection disc 4 and the inner walls of the two protective grooves 13 cooperate with each other to play a good role in clamping the mounting plate 8, making the mounting plate 8 more stable during use and preventing the mounting plate 8 and the heating tubes 12 on it from sliding during use.

[0048] During 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 several heating tubes 12 move, one end of several heating tubes 12 away from the mounting plate 8 can be sleeved on the support tube 24. During use, the support tube 24 can position and support one end of 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 position the two ends and the middle of the heating tube 12.

[0049] When the staff detects the heating tubes 12, the staff can connect the external detection connection wire to the connector 34, so that the detection connection wire powers several heating tubes 12 through the connector 34, the connecting piece 31, and the connecting block 9, enabling several heating tubes 12 to heat their surfaces and the surrounding air. 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 tubes 12 and the air temperature inside the two protective shells 2. During use, the heating efficiency of the heating tubes 12 on their surfaces and the heating uniformity of several heating tubes 12 can be detected. During use, it can also detect the situation where the heating tubes 12 cannot be heated due to connection problems.

[0050] After the staff finishes detecting the heating tubes 12, the staff can drive several fan blades 28 to rotate through the electric rotating shaft 26. When the fan blades 28 rotate, external air enters between several heating tubes 12 through the support tube 24 and flows through the gaps between several heating tubes 12 to the inside of the protective shell 2. During use, it can cool the surface of the heating tubes 12 and the air temperature inside the protective shell 2. It can also make the high-temperature air inside the two protective shells 2 flow to the outside through the support tube 24 by the rotation of the fan blades 28. Before the staff takes the heating tubes 12, the surface of the heating tubes 12 and the air inside the protective shell 2 can be cooled in advance to prevent the high-temperature air inside the protective shell 2 and the high temperature on the surface of the heating tubes 12 from causing harm to the staff when the two protective shells 2 are opened and the heating tubes 12 are 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 around the rotating block 20 in a direction away from the opposite surface until the outer wall of the protective shell 2 abuts against the limiting block 3. During use, the limiting block 3 can limit the rotation angle of the protective shell 2, and the staff can take out the mounting plate 8 and the heating pipe 12 inside the two protective shells 2 during use. When the two protective shells 2 rotate in a direction away from the opposite surface, the protective shell 2 can pull the detection disc 4 through the moving plate 19, so that the detection disc 4 moves in a direction away from the mounting plate 8. During use, the clamping of the mounting plate 8 can be released, which is convenient for the staff to take out the mounting plate 8 and the heating pipe 12. At the same time, when the two protective shells 2 rotate, the connecting piece 31 on the detection disc 4 can be automatically disconnected from the electrical connection with the connecting block 9 on the mounting plate 8, making it safer for the staff to take out the mounting plate 8 and the heating pipe 12.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
