A protective cover 101 is arranged in the placement groove for protecting and covering the pipeline monitoring instrument 9.

[0029] It should be noted that the upper arc sleeve 1 and the lower arc sleeve 2 have the same curvature and the same size, so that when the upper arc sleeve 1 and the lower arc sleeve 2 are assembled, they can be completely fitted, and after complete fitting, a smooth tubular structure is formed, so that the structure of the outer pipe can be formed by using the two enclosures, and the heat pipe can be more closely covered.

[0030] In actual operation, a detection opening is formed in the inner wall of the bottom end of the placement groove through the upper arc sleeve 1, so that when the pipeline monitoring instrument 9 is arranged in the placement groove, the detection end can more conveniently monitor the heat pipe through the detection opening, and the protective cover 101 used in the present application is made of transparent material, so that the pipeline monitoring instrument 9 can be viewed while being covered and protected.

[0033] Specifically, the connecting mechanism includes a first connecting block 3 and a second connecting block 4, a through slot 301 is formed in the middle of the top end of the first connecting block 3, a penetrating sliding slot 401 is formed in the middle of the top end of the second connecting block 4, both ends of the arc-shaped pressing rod 5 are slidingly connected in the through slot 301 and the penetrating sliding slot 401, and the locking member is horizontally and centrally symmetrically arranged on both sides of the through slot 301.

[0034] It should be noted that when the upper arc-shaped sleeve 1 and the lower arc-shaped sleeve 2 are aligned and attached to each other, the bottom end of the through slot 301 and the top end of the penetrating sliding slot 401 penetrate each other, so that when the both ends of the arc-shaped pressing rod 5 are inserted downward, they can be inserted into the penetrating sliding slot 401 through the through slot 301, so as to lock the first connecting block 3 and the second connecting block 4 by using the arc-shaped pressing rod 5.

[0035] In actual operation, the first connecting block 3 and the second connecting block 4 are the same size, so that when the upper arc-shaped sleeve 1 and the lower arc-shaped sleeve 2 are aligned and attached, the first connecting block 3 and the second connecting block 4 can also be aligned, so that the arc-shaped pressing rod 5 can smoothly pass through the through slot 301 and be inserted into the penetrating sliding slot 401 when pressed downward.

[0036] Further, the locking member includes a control pull block 8, the side close to the first connecting block 3 of the control pull block 8 is fixedly connected with a control pull rod 804, the control pull rod 804 penetrates into the through slot 301 from one side of the first connecting block 3, the inner walls on both sides of the penetrating sliding slot 401 are both provided with a control sliding slot 402, and the penetrating sliding slot 401 and the control sliding slot 402 are provided with a locking mechanism for cooperating with the control pull rod 804 to complete the downward penetration position of the arc-shaped pressing rod 5.

[0038] In actual operation, the control pull block 8 is always blocked at the side of the first connecting block 3, so that it can only pull away from the first connecting block 3 in the initial state, thereby driving the connected control pull rod 804 to move away from the first connecting block 3 in the horizontal direction, so that the connected structure can be controlled by the moving characteristics.

[0039] Further, the locking mechanism comprises a bidirectional tooth plate 403, a guide insertion slot 404 is formed in the middle of the bottom end of the bidirectional tooth plate 403, a guide insertion rod 405 is connected in the guide insertion slot 404, the bottom end of the guide insertion rod 405 is fixedly connected with the inner wall of the bottom end of the insertion slot 401, a positioning tooth plate 801 is arranged on the side of the control pull rod 804 away from the control pull block 8, and the tooth side of the positioning tooth plate 801 is in meshing connection with one side of the bidirectional tooth plate 403.

[0040] It should be noted that the side of the bidirectional tooth plate 403 in meshing connection with the positioning tooth plate 801 is vertically arranged with teeth on the whole side, so that no matter where the bidirectional tooth plate 403 moves vertically, it can be in meshing connection with the positioning tooth plate 801, and the positioning tooth plate 801 can be used to lock the bidirectional tooth plate 403 in real time, and the guide insertion rod 405 and the guide insertion slot 404 are in sliding insertion connection, so that the bidirectional tooth plate 403 can stably move vertically under the cooperation of the two structures, so that the bidirectional tooth plate 403 and the positioning tooth plate 801 are always in meshing connection at a height position.

[0041] In actual operation, the bidirectional tooth plate 403 moves vertically under the sliding guidance of the guide insertion slot 404 and the guide insertion rod 405, so that after the bidirectional tooth plate 403 moves to different height positions, the side close to the positioning tooth plate 801 is in meshing connection with the tooth side of the positioning tooth plate 801, and the positioning tooth plate 801 is connected with the control pull rod 804, so that the basic height of the positioning tooth plate 801 is the height region of the control pull rod 804, so that after the bidirectional tooth plate 403 moves to different height regions, the positioning tooth plate 801 locks the position.

[0042] Further, the other side of the bidirectional tooth plate 403 is in meshing connection with a driving gear 407, the middle part of the driving gear 407 is in insertion connection with a supporting rotating rod 406, the two ends of the supporting rotating rod 406 are in rotating insertion connection with the inner walls of the front and back surfaces of the control sliding slot 402, the two sides of the bottom of the arc-shaped pressing rod 5 are fixedly connected with driving tooth plates 501, and the tooth sides of the driving tooth plates 501 are in meshing connection with the outer wall of the side of the driving gear 407 close to the insertion slot 401.

[0043] It should be noted that through the above structural design, it is analyzed that when the first connecting block 3 and the second connecting block 4 are attached, the top of the bidirectional tooth plate 403 is inserted into the through groove 301, so that the movement of the bidirectional tooth plate 403 can be controlled by the rotation of the driving gear 407, so that the driving gear 407 can be controlled to rotate in the direction, and the bidirectional tooth plate 403 can be lifted and lowered in the vertical direction.

[0044] In actual operation, when the first connecting block 3 and the second connecting block 4 need to be locked, the control pull block 8 needs to be pulled away from the first connecting block 3, at this time the control pull rod 804 is driven by the control pull block 8 to drive the positioning tooth plate 801 to move synchronously, so that the engagement between the bidirectional tooth plate 403 and the positioning tooth plate 801 is released, at this time the arc-shaped pressing rod 5 can be pressed downward, the two ends of the arc-shaped pressing rod 5 are lowered, and the driving gear 501 is driven to move downward synchronously, at this time the driving gear 501 is engaged with the driving gear 407 to rotate, the driving gear 407 is driven by the engagement transmission to move the bidirectional tooth plate 403 upward, and when the arc-shaped pressing rod 5 cannot be lowered any more, the engagement between the positioning tooth plate 801 and the bidirectional tooth plate 403 is completed, and the positioning of the insertion position is completed.

[0045] Further, the control pull rod 804 is provided with a limiting sliding groove at the top and bottom of the first connecting block 3, and a supporting spring 803 is arranged in the limiting sliding groove.

[0046] It should be noted that when the control pull block 8 is pulled, the control pull rod 804 moves and drives the limiting sliding block 802 to move synchronously, the movement of the limiting sliding block 802 will extrude the supporting spring 803 in the limiting sliding groove to make it compress under force, so that after the pulling force of the control pull block 8 is released, the control pull rod 804 is reset under the action of the restoring force of the supporting spring 803, and through the above structure, the control pull rod 804 is always close to the first connecting block 3 under the driving of the limiting sliding block 802, so that the positioning tooth plate 801 can always be engaged with the bidirectional tooth plate 403, and the adjusted insertion can be positioned and locked.

[0047] The middle part of the bottom end of the arc-shaped pressing rod 5 is provided with a pressing mechanism.

[0048] Specifically, the pressing mechanism comprises a pressing block 6 and an extrusion block 7, the top end of the pressing block 6 is fixedly connected with the middle part of the bottom end of the arc-shaped pressing rod 5, the bottom of the pressing block 6 vertically penetrates one end of the upper arc-shaped sleeve 1, the bottom end of the pressing block 6 is provided with a receiving sliding groove 601, the top of the extrusion block 7 is slidably connected in the receiving sliding groove 601, and the bottom of the extrusion block 7 is horizontally provided with auxiliary pressing parts for pipe pressing.

[0049] It should be noted that the setting of the receiving chute 601 enables the extrusion block 7 to move up in the receiving chute 601 to complete the receiving after being subjected to the counter supporting force.

[0050] Further, the inner walls of the front and back surfaces of the receiving chute 601 are provided with guide grooves 602, and the inner wall of the top of the receiving chute 601 is provided with a downward spring 603.

[0051] It should be noted that when the extrusion block 7 is subjected to an upward supporting force and moves upward in the receiving chute 601, it will extrude the downward spring 603 in the receiving chute 601, so that the downward spring 603 is forced to contract, and the reaction force of the downward spring 603 downward enables the extrusion block 7 to be more closely fitted to the pipeline providing the upward supporting force. The structure design between the guide sliding block 704 and the guide groove 602 enables the sliding of the extrusion block 7 in the receiving chute 601 to be guided and limited, so that it can only move in the vertical direction, and it is also avoided from completely falling out of the receiving chute 601.

[0052] Further, the auxiliary pressing member includes an auxiliary pressing rod 701. The front and back surfaces of the bottom of the extrusion block 7 are provided with rotating grooves, and the top end of the auxiliary pressing rod 701 is connected in the rotating grooves.
