Detailed implementation manners

[0035] The following detailed description is given of the specific implementation manners of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, the directional terms such as "inside" and "outside" are with respect to the contour of the corresponding component itself; the directional terms such as "top", "bottom", "horizontal" and "vertical" are defined based on the usage habits of the blocking device provided in the present disclosure. Specifically, reference may be made to Figure 1 the drawing direction shown. The terms such as "first" and "second" used in the present disclosure are for distinguishing one element from another, and do not have sequence or importance. In addition, when the following description relates to the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements.

[0037] Refer to Figures 1 - 5, the present disclosure provides a blocking device, which may include a surrounding component 10, a mounting component 20, and a connecting component 30. Among them, the surrounding component 10 may include a first blocking frame 11 and a second blocking frame 12, and the first blocking frame 11 and the second blocking frame 12 can be selectively butted against each other in the horizontal direction so as to be able to surround the high-temperature area of the heat recovery device 100. When the first blocking frame 11 and the second blocking frame 12 are butted, the first blocking frame 11 and the second blocking frame 12 can jointly form a surrounding structure, thereby effectively isolating the high-temperature area and reducing the possibility of accidentally touching the high-temperature area. When the recovery device 100 has the need for maintenance, the first blocking frame 11 and the second blocking frame 12 can cancel the butt joint to adjust the relative positions of the two blocking frames, thereby canceling the isolation of the high-temperature area to facilitate the operation of the staff. The mounting component 20 may include a support cross beam 21 extending horizontally and fixed at a preset position. The first blocking frame 11 and the second blocking frame 12 are erected on the support cross beam 21, that is, the support cross beam 21 provides an installation foundation for the first blocking frame 11 and the second blocking frame 12 at the preset position, effectively ensuring the stability of the installation positions of the first blocking frame 11 and the second blocking frame 12. The connecting component 30 can be used to mount the first blocking frame 11 and the second blocking frame 12 on the support cross beam 21, thereby ensuring the connection stability between the first blocking frame 11 and the second blocking frame 12 and the support cross beam 21 and the overall effect of the device. The connecting component 30 can be configured to enable the first blocking frame 11 and the second blocking frame 12 to swing in the horizontal plane to have a butted state and a separated state, so that the operator can adjust the positions of the two blocking frames as needed, facilitating the surrounding or removal of the surrounding of the high-temperature area, improving the convenience and flexibility of the operation, and at the same time enhancing the applicability and practicality of the overall device.

[0038] Through the above technical solution, the first blocking frame 11 and the second blocking frame 12 can be butted or separated as needed, so as to flexibly adapt to different working environments and requirements. By fixing the first blocking frame 11 and the second blocking frame 12 with the support cross beam 21, the stability and reliability of the blocking device are ensured. The blocking device of the present disclosure not only improves the safety of the heat energy recovery device through the settings of the surrounding component 10, the mounting component 20, and the connecting component 30, avoids the possibility of the operator accidentally touching the high-temperature area, but also facilitates the maintenance and management of the device, has good practicality and convenience, and can effectively meet the safety management requirements in the high-temperature environment.

[0039] Referring to Figure 1 and Figure 5, the connecting assembly 30 may include two rotating longitudinal beams 31, and the two rotating longitudinal beams 31 are respectively fixedly connected to both ends of the supporting cross beam 21 in the vertical direction. Correspondingly, the enclosure assembly 10 may include two side beams 13, and the two side beams 13 are respectively coaxially and rotatably connected to the two rotating longitudinal beams 31, and the two side beams 13 are respectively fixedly connected to the two sides of the first retaining frame 11 and the second retaining frame 12 that are far away from each other. Specifically, the two side beams 13 may respectively include a first side beam 131 fixed to the first retaining frame 11 and a second side beam 132 fixed to the second retaining frame 12. The first side beam 131 and the second side beam 132 may be respectively connected to a rotating longitudinal beam 31, so that the connecting assembly 30 and the enclosure assembly 10 can work together, realizing the swing of the first retaining frame 11 and the second retaining frame 12 in the horizontal plane while maintaining a stable connection. In the embodiment provided by the present disclosure, the first side beam 131 and the second side beam 132 may respectively be tubular structures, and the two rotating longitudinal beams 31 are respectively coaxially inserted into the first side beam 131 and the second side beam 132 one by one, so that the first retaining frame 11 and the second retaining frame 12 can rotate around the axis of the corresponding rotating longitudinal beam 31. Through this matching method, the operator can easily adjust the positions of the two retaining frames, ensuring the flexibility and convenience of the blocking device, and at the same time improving the operation efficiency and stability of the blocking device.

[0040] Referring to Figure 1 , Figure 3 and Figure 5 , the mounting assembly 20 may further include a first mounting plate 22, and the first mounting plate 22 may include a vertical section 221 and a horizontal section 222 that are perpendicularly connected to each other. In the embodiment provided by the present disclosure, the perpendicular connection of the vertical section 221 and the horizontal section 222 may be configured as an inverted L-shaped cross-section structure, or configured as a semi-surrounding structure with an inverted L-shaped cross-section in the vertical direction as shown in the embodiment of Figure 5 , which can effectively ensure the structural strength of the first mounting plate 22 itself. As shown in Figure 5 , the opening of the L-shaped structure may be arranged in a direction away from the heat recovery device, so as to limit the rotation range of the first retaining frame 11 and the second retaining frame 12, and further effectively prevent the first retaining frame 11 and the second retaining frame 12 from rotating excessively during the process of switching from the separated state to the docking state, for example, so as to prevent the two retaining frames from rubbing against the heat recovery device 100. As shown in Figure 5As shown, the bottom end of the vertical section 221 can be fixedly connected to the support crossbeam 21, and both ends of the rotating longitudinal beam 31 can be respectively fixedly connected to the horizontal section 222 and the support crossbeam 21. The support crossbeam and the rotating longitudinal beam can be firmly connected through the first mounting plate 22, providing a stable support structure for the entire enclosure device, enabling the enclosure assembly 10 and the connection assembly 30 to be effectively connected to the support structure, and ensuring strong stability during the process of switching between the docking state and the separation state of the two retaining frames. At the same time, the stability and reliability of the entire enclosure device are also improved.

[0041] Referring to Figure 1 and Figure 3 , the first retaining frame 11 and the second retaining frame 12 are configured to form a first U-shaped structure with an opening facing the high-temperature area when they are docked with each other. The first U-shaped structure can jointly form an annular closed structure with the body 101 mentioned below, thereby effectively isolating the high-temperature area to further ensure the safety of the operator. At the same time, it can also reduce the use of other components, meeting the principle of lightweight design.

[0042] Referring to Figure 1 , Figure 2 and Figure 5 , the mounting assembly 20 may further include two limit posts 23 and a limit sleeve 24. The two limit posts 23 can be fixedly connected to the first retaining frame 11 and the second retaining frame 12 in a one-to-one correspondence. In the embodiment provided by the present disclosure, the enclosure assembly 10 may further include a first top beam 141 provided on the top of the first retaining frame 11 and a second top beam 142 provided on the top of the second retaining frame 12. The two limit posts 23 can be respectively provided on the first top beam 141 and the second top beam 142. The limit sleeve 24 can be sleeved on the two limit posts 23 jointly when the first retaining frame 11 and the second retaining frame 12 are docked to limit the relative positions of the first retaining frame 11 and the second retaining frame 12, thereby ensuring the stability when the first retaining frame 11 and the second retaining frame 12 enclose the high-temperature area and avoiding the problem of accidental opening of the first retaining frame 11 and the second retaining frame 12. When there is a need to separate the first retaining frame 11 and the second retaining frame 12, it is only necessary to disassemble the limit sleeve 24 from the two limit posts 23 to cancel the limitation of the relative positions of the first retaining frame 11 and the second retaining frame 12. Referring to Figure 5 , a handle can be provided on the limit sleeve 24 provided by the present disclosure to facilitate the operator to pick up the limit sleeve 24.

[0043] Referring to Figure 1 and Figure 5, the connecting component 30 may further include a plurality of rollers 32. The plurality of rollers 32 may be respectively rotatably connected to the bottoms of the first retaining frame 11 and the second retaining frame 12, so as to facilitate the movement of the first retaining frame 11 and the second retaining frame 12. While improving the moving efficiency of the first retaining frame 11 and the second retaining frame 12, the moving difficulty of the first retaining frame 11 and the second retaining frame 12 can be reduced. Refer to Figure 1 and Figure 5 , the connecting component 30 further includes a second mounting plate 33 for mounting the rollers 32. One end of the second mounting plate 33 is connected to the bottom of the enclosure component, and the other end extends away from the enclosure component 10 and protrudes beyond the support cross beam 21 to prevent the rollers 32 from interfering with the support cross beam 21. In the embodiment provided by the present disclosure, a plurality of rollers 32 may be arranged at intervals in the horizontal direction, and the number of the second mounting plates 33 may match the number of the rollers 32 to respectively mount the rollers 32. In this way, when a certain roller 32 or the second mounting plate 33 is damaged and needs to be replaced, the normal use of other rollers 32 will not be affected.

[0044] Refer to Figure 1 、 Figure 2 and Figure 4 , the blocking device may further include a placing component 40, and the placing component 40 may include a placing plate 41 and a clamping plate 42. The placing plate 41 may be mounted on one of the first retaining frame 11 and the second retaining frame 12, or as Figure 4 shown, a placing plate 41 is respectively provided on the first retaining frame 11 and the second retaining frame 12. The clamping plate 42 may be rotatably connected to the placing plate 41 in an openable and closable manner for clamping information paper. In the embodiment provided by the present disclosure, the clamping plate 42 may be made of a transparent material, or the clamping plate 42 is also configured as a plate surface hollowing structure as Figure 4 shown, so as to facilitate the operator to read device information, etc.

[0045] Refer to Figure 1 、 Figure 2 and Figure 4The cross-section of the placement plate 41 is a second U-shaped structure. During installation, the second U-shaped structure can be buckled on the top beam 14 of the first blocking frame 11 or the second blocking frame 12. The top beam 14 can include the first top beam 141 and the second top beam 142 mentioned above. In the embodiment provided by the present disclosure, a placement plate 41 is respectively provided on the first blocking frame 11 and the second blocking frame 12, and the two U-shaped structures can be buckled on the first top beam 141 and the second top beam 142 respectively. The second U-shaped structure can include a first side wall 411 arranged opposite to the opening of the second U-shaped structure and a second side wall 412 connected to both ends of the first side wall 411 and formed on both sides of the opening. The two first side walls 411 can respectively abut against the first top beam 141 and the second top beam 142 to fit on the top surfaces of the first top beam 141 and the second top beam 142, thereby ensuring the reliability of the installation of the placement plate 41 and preventing the first blocking frame 11 and the second blocking frame 12 from being separated from the installation position during the rotation process. The clamping plate 42 can be placed on the outside of the second side wall 412 to facilitate the operator's observation and placement of the information paper. In the embodiment provided in the present disclosure, the second side wall 412 can be arranged to fit the sides of the two guard frames to further improve the connection strength and overall effect of the placement plate 41 and the two guard frames.

The number of magnetic strips 43 can be multiple, and multiple magnetic strips 43 can be arranged on the clamping plate 42 at intervals to ensure the uniform distribution of magnetic force, thereby improving the magnetic attraction strength of the clamping plate 42 and the placement plate 41. The placement plate 41 and the clamping plate 42 cooperate through magnetic attraction, and can also be fixed by the clamping plate 42 when warning slogans need to be posted. While fixing the information paper, it can also facilitate the replacement of the information paper. A handle 44 can be provided on the side of the clamping plate 42 away from the placement plate 41. The clamping plate 42 can be driven to move relative to the placement plate 41 by pushing or pulling the handle 44, so as to fix or replace the information paper.
