[0001] The invention relates to the field of bundled temperature difference testing of the temperature difference of a hot rod condensing section, and in particular to a bundled temperature difference testing device for measuring the temperature difference of a hot rod condensing section. Background Art
[0002] As an active refrigeration device for gas-liquid two-phase conversion, the heat rod plays an active role in the thermal stability maintenance of the roadbed and bridge foundation in the permafrost area of the Qinghai-Tibet Railway. During the factory acceptance test of the heat rod, the start-up performance and isothermal performance test of the heat rod are carried out in accordance with the corporate standard of the Qinghai-Tibet Railway Company "Technical Specifications and Acceptance Standards for Heat Rods of the Qinghai-Tibet Railway Company". During the test, the evaporation section of the heat rod is placed in a basically constant temperature water bath, and the difference between the water temperature and the ambient temperature is controlled at 20±5℃. The evaporation section of the heat rod is placed in water (the inclination angle of the heat rod is about 15°), and the temperature of the central temperature measuring hole and the condensation section is read at different times. During the test, a bundled temperature difference test device is required; The bundled temperature difference test device currently used to measure the temperature difference of the condensing section of the hot rod needs to be put on the surface of the hot rod when in use, so as to facilitate the subsequent temperature difference test. However, the current test device is mostly tied with ropes during use, which not only requires manual bundling, but also may cause the binding ropes to loosen after long-term use, thereby causing the temperature difference test device to fall off, thereby affecting the subsequent test of the hot rod, and the overall practicality is low. Summary of the invention

However, the current testing device is mostly tied up by ropes during use, which not only requires manual bundling, but also may cause the binding ropes to loosen after long-term use, thereby causing the temperature difference testing device to fall off, thereby affecting the subsequent testing of the hot rod, and the overall technical problem of low practicality.
[0004] To solve the above technical problems, the present invention provides the following technical solutions: a bundled temperature difference test device for measuring the temperature difference of a condensing section of a hot rod, comprising a temperature difference test device body, a slide rail being provided on the front surface of the temperature difference test device body, a groove being provided at the bottom corner of the front end of the temperature difference test device body, and a winding roller being arranged on the inner side of the groove, a first elastic band being sleeved on the outer surface of the winding roller, and a connecting block being fixedly connected to the other end of the first elastic band, a torsion spring being sleeved on the outer side of one end of the winding roller, a slot being provided in the inner cavity of the connecting block, and a lock hole being connected to one side of the slot, guide grooves being symmetrically distributed on both sides of the slot, a second elastic band being distributed on the side of the temperature difference test device body away from the first elastic band, and an insert block being fixedly connected to the other end of the second elastic band, a guide rod being distributed on one side of the insert block, and a locking structure being fixedly connected to the inner side of the insert block.
[0005] As a preferred technical solution of the present invention, the locking structure includes a return spring, a locking block and an auxiliary slide plate. The return spring is fixedly connected to the inner side of the plug block, and the other end of the return spring is fixedly connected to the locking block. An auxiliary slide plate is sleeved on the outer side of one end of the locking block.
[0006] As a preferred technical solution of the present invention, an arc-shaped seat is fixedly connected to the bottom of the temperature difference testing device body, and a detection head is distributed on the inner side of the bottom of the arc-shaped seat.
[0007] As a preferred technical solution of the present invention, an end cover is sleeved on the outer side of the top end of the temperature difference testing device body, and a clamping strip is arranged on the inner side of the bottom of the end cover, an adapting groove is opened on the inner side wall of the end cover, and a heat conducting plate is clamped on the inner side of the adapting groove.
[0008] As a preferred technical solution of the present invention, the winding rollers are symmetrically distributed along the vertical center line of the temperature difference testing device body, and the winding rollers are rotationally connected to the temperature difference testing device body.
[0009] As a preferred technical solution of the present invention, the locking holes are symmetrically distributed along the transverse center line of the connecting block, and the locking holes and the connecting block form an integrated structure.

[0011] As a preferred technical solution of the present invention, the end cover is slidably connected to the main body of the temperature difference testing device through a clamping strip, and the clamping strip is symmetrically distributed along the vertical center line of the end cover.
[0012] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. By using the combination of the winding rod, elastic band, connecting block and plug block, the whole test device and the hot rod can be quickly bundled together in the subsequent use. Compared with the existing method of bundling by rope, it is more convenient and faster, more practical, and can be adjusted according to different sizes of hot rods. It is no longer necessary to bundle manually. Since the elastic band itself has a certain elasticity, it can be stretched. Therefore, when in use, the elastic band can be stretched according to the actual size of the hot rod. With the connection block and plug block, it is convenient to quickly connect and disassemble the two elastic bands in the subsequent use. 2. By using the reset spring, the locking block and the auxiliary slide in combination, the subsequent snap connection between the plug block and the connecting block can be facilitated. When the plug block is input into the inner side of the connecting block, the reverse force generated by the deformation of the reset spring will push the locking block, and then the locking block will move longitudinally. When one end of the locking block is input into the inner side of the locking hole, the connecting block and the plug block can be quickly connected. The auxiliary slide can improve the stability of the locking block during its movement. BRIEF DESCRIPTION OF THE DRAWINGS
