Description

Technical Field

[0001] This utility model relates to the technical field of temperature monitoring equipment, specifically a temperature monitoring device for the interior of an ancient building. Background Technology

[0002] Ancient buildings refer to civil and public buildings that were built before the founding of the People's Republic of China and have historical significance. In China, many ancient towns and most major cities still retain some ancient buildings. The internal temperature and humidity play an important role in the preservation of these ancient buildings, and relevant monitoring equipment is usually used to observe the real-time changes in temperature and humidity inside them.

[0003] Existing temperature monitoring devices inside ancient buildings are usually fixed directly to the building walls or pillars with bolts, causing damage to the ancient buildings. In particular, fixing the temperature monitoring devices to wooden support pillars can damage the support pillars, including but not limited to peeling of paint and gnawing by insects. Utility Model Content

[0004] The purpose of this invention is to provide an internal temperature monitoring device for ancient buildings that uses a circumferential adaptive surrounding structure with a split arc-shaped fixing block, allowing the fixed support column to be installed without fitting into a closed loop; and combines dovetail tenon joints and negative pressure adsorption for dual fixing, achieving zero drilling damage and protecting the integrity of the ancient building surface, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, an internal temperature monitoring device for ancient buildings is provided, comprising a biomimetic fixing arm that surrounds a support column, and a placement frame for holding a temperature detector is screwed onto the outer side of the biomimetic fixing arm. The biomimetic fixing arm includes multiple arc-shaped fixing blocks connected end to end in sequence.

[0006] Furthermore, the inner wall of the arc-shaped fixing block is provided with an adsorption plate, and the cavity surrounded by the adsorption plate constitutes an adsorption cavity. The bottom of the adsorption cavity is provided with a one-way valve that communicates with the outside. Dovetail tenons are provided on both sides of the arc-shaped fixing block, and the cavity between the two dovetail tenons is a dovetail tenon groove.

[0007] Furthermore, the male dovetail tenon has a pin hole along the radial direction, and a fixing pin for fixing two arc-shaped fixing blocks is provided in the pin hole.

[0008] Furthermore, permanent magnets (neodymium iron boron magnets) are provided on the inner side of the mating end faces on both sides of the arc-shaped fixing blocks, and the polarities of the permanent magnets of adjacent arc-shaped fixing blocks are arranged in an alternating N-S pole configuration.

[0009] Furthermore, the temperature detector 3 adopts the Onset (HOBO) MX1101 / UX100-011 series.

[0010] This invention offers the following advantages over existing technologies: By using the negative pressure adsorption fixing method of the adsorption plate, the surface of the support column is completely free from drilling or bolt compression, thus eliminating the risk of paint peeling and insect infestation; the number of arc-shaped fixing blocks is precisely controlled by combining the perimeter, achieving a full-circumferential stress-free fit between the bionic fixing arm and the column; ultimately achieving zero-damage protection and diameter adaptive installation for the wooden support column of ancient buildings.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see the appendix Figure 1 and Figure 2 As shown in the figure, this application discloses an internal temperature monitoring device for ancient buildings, including a biomimetic fixing arm 1 that surrounds a support column 4, and a placement frame 2 for holding a temperature detector 3 screwed onto the outer side of the biomimetic fixing arm 1. Please refer to the attached drawing. Figure 3 As shown, the bionic fixing arm 1 includes a plurality of arc-shaped fixing blocks 101 connected end to end.

[0020] This embodiment provides an internal temperature monitoring device for ancient buildings, which is used to non-destructively fix to the surface of the wooden support column 4 of the ancient building. The device mainly consists of a bionic fixing arm 1, a placement frame 2, and a temperature detector 3. The bionic fixing arm 1 is formed by connecting at least six arc-shaped fixing blocks 101 end to end to form a ring structure. Its inner diameter matches the outer diameter of the support column 4. The placement frame 2 is fixed to the outer side of the bionic fixing arm 1 by bolts. The temperature detector 3 is snapped into the inside of the placement frame 2. The temperature detector 3 adopts the OnsetHOBO MX1101 / UX100-011 series sensor.

[0021] In addition, please see the appendix. Figure 5 As shown, the inner wall of the arc-shaped fixing block 101 is provided with an adsorption plate 104, and the cavity surrounded by the adsorption plate 104 constitutes an adsorption cavity 107. Dovetail tenons 103 are provided on both sides of the arc-shaped fixing block 101, and the cavity between the two dovetail tenons 103 is a dovetail tenon groove 105.

[0022] In addition, please see the appendix. Figure 5 As shown, the male dovetail tenon 103 has a pin hole 106 in the radial direction, and a fixing pin 102 for fixing two arc-shaped fixing blocks 101 is provided in the pin hole 106.

[0023] In addition, permanent magnets (neodymium iron boron magnets) are provided on the inner side of the mating end faces on both sides of the arc-shaped fixing block 101, specifically arranged 5-8mm inside the root of the dovetail tenon male head 103. The axis of the permanent magnet 108 is parallel to the insertion direction of the dovetail tenon male head 103, and the polarities of the permanent magnets of adjacent arc-shaped fixing blocks 101 are arranged in an alternating N-S pole configuration.

[0024] In this embodiment, a single arc-shaped fixing block 101 is an arc-shaped component with a central angle of 10 to 20 degrees, which is injection molded from polycarbonate material. Its inner wall is provided with a silicone adsorption plate 104. The outer edge of the adsorption plate 104 is bonded and fixed to the inner wall of the arc-shaped fixing block 101. The cavity formed by the adsorption plate 104 constitutes an adsorption chamber 107. A one-way exhaust valve is provided at the top of the adsorption chamber 107. During operation, the arc-shaped fixing block 101 is squeezed radially by external force, so that the air in the adsorption chamber 107 is discharged through the one-way valve. When the external force is removed, the adsorption plate 104 is adsorbed onto the surface of the support column 4 due to the negative pressure of the cavity.

[0025] The two ends of the arc-shaped fixing block 101 are integrally formed with dovetail tenons 103. The gap between the dovetail tenons 103 forms a dovetail tenon groove 105. The dovetail tenon 103 is a trapezoidal boss structure with an inclined angle of 15°. The dovetail tenon 103 and the trapezoidal groove of the dovetail tenon groove 105 form an interference fit. A cylindrical pin hole 106 with a diameter of 2-5mm is radially opened in the middle of the dovetail tenon 103. The pin hole 106 penetrates the dovetail tenon 103. When the two arcs are closed... When the two curved fixing blocks 101 are joined, the male dovetail tenon 103 on the left side of one of the blocks is inserted into the female dovetail tenon 105 of the adjacent block to form an interlocking structure. Then, mechanical locking is achieved by inserting the fixing pin 102 into the aligned pin hole 106. The fixing pin 102 is made of 304 stainless steel and has an anti-disengagement spring at the end. Neodymium iron boron permanent magnets are embedded in the two end faces of the curved fixing blocks 101. The magnetic attraction force generated by the permanent magnets provides auxiliary attraction force for fixing the two curved fixing blocks 101.

[0026] During assembly, first, the perimeter of the support column 4 is measured and the number of arc-shaped fixing blocks 101 required is calculated. Then, one arc-shaped fixing block 101 is randomly selected, and its right dovetail tenon male head 103 is inserted into the left dovetail tenon female groove 105 of the second arc-shaped fixing block 101. Then, the two arc-shaped fixing blocks 101 are fixed by inserting the fixing pin 102 into the pin hole 106. Then, this step is repeated until the N-1th block is connected. At this time, the dovetail tenon male head 103 and dovetail tenon female groove 105 are left exposed at both ends of the bionic fixing arm 1. That is, after multiple arc-shaped fixing blocks 101 are connected by the mortise and tenon joint, the last interface is left so that the bionic fixing arm 1 can be wrapped around the outer side of the support column 4.

[0027] The connected open chain is wrapped around the support column 4 once, and then negative pressure is applied to fix it. Press the center area of ​​each arc-shaped fixing block 101 in sequence along the circumference, and apply radial pressure for several seconds to make the air in the adsorption chamber 107 be discharged from the one-way valve. After the force is released, the silicone adsorption plate 104 is adsorbed on the column surface due to the negative pressure. Visually confirm that the edges of each adsorption plate 104 are not raised.

[0028] Finally, the two ends of the bionic fixed arm 1 meet on the surface of the column. The operator holds the arc-shaped fixed block 101 at the beginning with one hand and aligns the male dovetail tenon 103 at the end with the female dovetail tenon 105 at the beginning with the other hand to complete the tenon and mortise joint. Then, the fixing pin 102 is inserted into the pin hole 106 to achieve mechanical locking, thus forming a complete closed loop of the bionic fixed arm 1. Then, the placement frame 2 is fixed to the outer side of an arc-shaped fixed block 101 with bolts and the temperature detector 3 is inserted into the placement frame 2.

[0029] This application achieves adaptive covering through a split arc-shaped fixing block 101, eliminating structural damage caused by traditional bolt drilling. The adsorption plate 104 and dovetail joint form a double fixing mechanism, ensuring a load-bearing capacity of over 10kg while avoiding wear on the column surface paint layer. The detachable structure facilitates maintenance, and there are no residual indentations on the surface of the support column 4 after disassembly. Actual testing shows that this device is suitable for wooden cylinders with a diameter of 200-500mm, and works stably in a temperature range of -10℃ to 50℃ and a humidity environment of 30%-90%RH. The total weight is less than 1.2kg, and it does not impose any additional load on the load-bearing structure of ancient buildings.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
