Description

Technical Field

[0001] The present invention belongs to the technical field of thermal control instruments, and particularly relates to an installation device for thermal control instruments. Background Art

[0002] In an industrial automation control system, thermal control instruments (such as temperature sensors, pressure transmitters, etc.) usually need to be installed in high-temperature, vibrating or corrosive environments; the existing installation devices for thermal control instruments generally have the following problems:

[0003] I. Poor adaptability and complex disassembly and assembly

[0004] Traditional installation devices usually adopt a dual-mechanism fixation mode, that is, the left and right sides or the upper and lower ends of the thermal control instrument are fixed by two independent clamping mechanisms respectively, resulting in a cumbersome installation and disassembly process, requiring multiple adjustments of screws or buckles, with low operation efficiency; and due to the different size specifications of thermal control instruments (such as different lengths, widths, and thicknesses), existing fixation mechanisms often need to replace different specifications of jigs or adjust multiple fasteners, with poor versatility, increasing the maintenance cost;

[0006] When a thermal control instrument works in a high-temperature environment, if its installation bracket uses ordinary metal materials (such as stainless steel, carbon steel), it is easy to cause the temperature of the instrument body to rise due to heat conduction, thereby affecting the measurement accuracy.

[0045] Embodiment 1

[0046] Reference Figures 1-4 , this embodiment provides a thermal control instrument installation device, including an installation plate 4, a fixing mechanism 1, and a heat dissipation mechanism 2; the installation plate 4 is fixed to the wall through fasteners; the fixing mechanism 1 includes a bottom plate 11, a first fixing component 13 connected to the bottom plate 11, and a second fixing component 14 connected to the first fixing component 13; the heat dissipation mechanism 2 is connected to the fixing mechanism 1 and is used to dissipate heat from the thermal control instrument 3;

[0047] The first fixing component 13 is used to clamp and fix the first side, the second side, and the third side of the thermal control instrument 3, wherein the first side and the second side of the thermal control instrument 3 are opposite, and the third side is adjacent to the first side and the second side respectively;

[0049] Specifically, the first fixing component 13 includes a pair of first side plates 136, a bidirectional lead screw 131, guide rods 132, a pair of nuts 133, a pair of "┕"-shaped clamping blocks 134, and a motor 135;

[0050] A pair of the first side plates 136 are respectively vertically connected to both sides of the bottom plate 11;

[0051] Both ends of the bidirectional lead screw 131 are respectively connected to the two first side plates 136 through bearings;

[0052] Both ends of the guide rod 132 are respectively connected to the two first side plates 136;

[0053] A pair of nuts 133 are respectively threadedly connected to the two threaded sections of the bidirectional lead screw 131;

[0054] A pair of "┕"-shaped clamping blocks 134 are respectively connected to the two nuts 133, and a pair of "┕"-shaped clamping blocks 134 are movably connected to the guide rod 132;

[0055] The motor 135 is arranged outside one of the side plates 136, and its output end is connected to one end of the bidirectional lead screw 131.

[0056] Specifically, the second fixing component 14 includes a side plate two 141, four rotating rods 142, a pair of "┕"-shaped connecting rods 143, and an elastic pad two 147;

[0057] The side plate two 141 is slidably connected to a chute 111 opened above the bottom plate 11; a rotating seat one 145 is provided on the side of the side plate two 141 away from the thermal control instrument 3;

[0058] The four rotating rods 142 are interconnected by a plurality of rotating shafts 144 to form an equilateral parallelogram, and two adjacent rotating rods 142 are rotatably connected to the side plate two 141; the remaining two rotating rods 142 are also rotatably connected to a rotating seat two 146 through a rotating shaft 144, and the rotating seat two 146 is arranged on the mounting plate 4, and the mounting plate 4 is vertically connected to the bottom plate 11;

[0059] One end of a pair of "┕"-shaped connecting rods 143 is respectively connected to a pair of "┕"-shaped clamping blocks 134, and the other end is rotatably connected to the rotating rod 142 through two opposite rotating shafts 144;

[0060] The elastic pad two 147 is arranged inside the side plate two 141.

[0061] In order to absorb the vibration of the equipment and prevent it from being transmitted to the thermal control instrument 3 to affect the reading, in this embodiment, the abutting plate 15 is made of high-damping silicone rubber or nitrile rubber (NBR).

[0062] In order to prevent the thermal control instrument 3 from being damaged due to excessive clamping, in this embodiment, the first fixing component 13 further includes two "┕"-shaped elastic pads 137, and the "┕"-shaped elastic pads 137 are respectively arranged on the sides of the two "┕"-shaped clamping blocks 134 close to the thermal control instrument 3.

[0063] Furthermore, a pressure sensor is embedded in the "┕"-shaped elastic pad 137, the pressure sensor is electrically connected through an external controller, and the output end of the external controller is electrically connected to the motor 135, and is used to control the motor 135 to turn off when the pressure of the pressure sensor exceeds a set threshold.

[0064] Furthermore, a plurality of abutting plates 15 are further included, the abutting plates 15 are arranged at the bottom of the thermal control instrument 3, and are vertically connected to the upper part of the bottom plate 11.

[0065] Preferably, during use, first place the thermal control instrument 3 to be installed on the abutting plate 15, and then start the motor 135. When the motor 135 drives the bidirectional lead screw 131 to rotate, the left-handed thread section drives the left nut 133 to move along the axial direction 1 (for example, to the left); the right-handed thread section drives the right nut 133 to move along the axial direction 2 (for example, to the right); due to the opposite thread directions, the two nuts 133 always move symmetrically and in opposite directions, ensuring that a pair of "┕"-shaped clamping blocks 134 approach or move away synchronously. The guide rod 132 restricts the circumferential rotation of the nut 133 and forces it to only perform axial translation to avoid jamming. When a pair of "┕"-shaped clamping blocks 134 move to both sides of the thermal control instrument 3 and the clamping force of the pressure sensor in the "┕"-shaped elastic pad 137 reaches a predetermined threshold, it is transmitted to the external controller through an electrical signal. The external controller sends it to the motor 135 to control the motor 135 to turn off. At the same time, when a pair of "┕"-shaped clamping blocks 1 mutually approach, the included angle of the two rotating rods 142 connected to the second side plate 141 becomes smaller, so that the second side plate 141 approaches the fourth side of the thermal control instrument 3 until the second elastic pad 147 contacts it for positioning.

[0066] In this embodiment, the present invention designs the first fixing component 13. The bidirectional lead screw 131 is automatically controlled by the motor 135 to drive the "┕"-shaped clamping blocks to move synchronously, realizing the synchronous clamping of three sides (the first, second, and third sides) of the thermal control instrument 3. There is no need to manually adjust the screws one by one, significantly improving the installation efficiency, and it can be adapted to thermal control instruments 3 of different lengths. Among them, a pair of "┕"-shaped clamping blocks are also connected with a second fixing component 14. The rotating rod 142 of the second fixing component 14 is linked with the "┕"-shaped connecting rod. When clamping the three sides of the thermal control instrument 3, it automatically pulls the second side plate 141 on the fourth side to press the thermal control instrument 3, forming a four-sided adaptive fixation, avoiding the cumbersome process of traditional dual-mechanism independent adjustment. And an elastic pad 147 is provided on the inner side of the second side plate 141, and a "┕"-shaped elastic pad is provided on the inner side of the "┕"-shaped clamping block. The elastic pad provides buffering to prevent damage to the surface of the thermal control instrument 3 due to over-tight clamping. The above design solves the problems of poor adaptability and complex disassembly and assembly in the traditional installation device.

[0070] Each of the heat dissipation fins 22 is respectively installed on the side of the second side plate 141 away from the thermal control instrument 3 by screws.

[0071] In order to be applicable to intermittent high-temperature working conditions and avoid overheating drift of electronic components, in this embodiment, paraffin-based phase change materials are also filled in the two "┕"-shaped heat dissipation fins 21 and several second heat dissipation fins 22.

[0072] In this embodiment, the present invention introduces a heat dissipation mechanism 2. Through the combination of "┕"-shaped heat dissipation fins, second heat dissipation fins 22 and phase change materials, it is directly installed on the "┕"-shaped clamping block and the second side plate 141, and the heat of the thermal control instrument 3 is quickly transferred to the outside through metal heat conduction; the paraffin-based phase change material absorbs heat and melts at high temperatures, delaying the temperature rise of the thermal control instrument 3, which is particularly applicable to intermittent high-temperature working conditions, avoiding overheating drift of electronic components, and solving the problem of reduced accuracy of the thermal control instrument 3 caused by insufficient heat dissipation.

[0073] In summary, the present invention realizes the adaptive and rapid installation of the thermal control instrument 3 through the bidirectional lead screw 131 to drive the three-side synchronous clamping mechanism and the linkage fourth-side fixing mechanism 1. Combining with the efficient heat dissipation system and the buffer protection design, it effectively solves the problems of poor adaptability, cumbersome disassembly and assembly, and poor heat dissipation of the traditional installation device, and significantly improves the installation efficiency, versatility and working stability of the thermal control instrument 3.

[0074] The above is only the preferred embodiment of the present invention.
