Description

Technical Field

[0001] This utility model relates to the field of data acquisition terminal technology, specifically to an electrical parameter acquisition device for a cable monitoring system. Background Technology

[0002] Existing electrical parameter acquisition devices are typically box-type acquisition terminals containing circuit boards with numerous electrical components. These devices generate a certain amount of heat during operation. While this temperature is not a problem under normal operating conditions, it can easily exceed safe operating limits in high-temperature environments, such as inside distribution boxes. This can negatively impact performance. Installing internal heat dissipation devices would increase the device's size, which would be cumbersome if heat dissipation is not required. Therefore, adapting electrical parameter acquisition devices to different installation environments is a crucial issue that needs to be addressed. Utility Model Content

[0015] 1. The electrical parameter acquisition device of this cable monitoring system is designed with a modular heat dissipation module. When the acquisition device is used in high temperature weather or in a high temperature environment, the heat dissipation module can be added to better dissipate heat from the internal circuit board, avoid high temperature from reducing its performance, and improve the safety of use.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following three technical solutions:

[0025] First implementation: An electrical parameter acquisition device for a cable monitoring system, comprising a housing 1, with a circuit board 2 fixedly connected to one side of the inner wall of the housing 1 by screws (as shown in Publication No. CN114460424A, an online testing system for the insulation of railway signal cables to ground, which includes a relay contact network, an insulation test meter, a comprehensive acquisition unit, and a test terminal, wherein the comprehensive acquisition unit is connected to the relay contact network, the insulation test meter, and the test terminal respectively, the relay contact network is connected to the insulation test meter, and the relay contact network is connected to the railway signal cable under test. This application belongs to the comprehensive acquisition unit part of the testing system, which realizes the monitoring of the cable by connecting the relay contact network to the railway signal cable under test). It also includes:

[0026] End box 3 is fixedly connected to one end of outer shell 1. Several serial ports are fixedly connected inside end box 3 for connecting the cable monitoring system line plug.

[0027] The heat dissipation module 4 is plugged into the other end of the outer shell 1 and is used to dissipate heat from the circuit board 2. The heat dissipation module 4 can be hung on the whole unit by a hook-type vent pipe (if it is installed in equipment such as a distribution box, a hole can be opened on the box to extend the vent pipe to the outside for ventilation. At this time, the vent pipe is equivalent to being hung on the box wall).

[0028] When the heat dissipation module 4 is not installed on the top of the outer casing 1, it is sealed by inserting and installing the end cover 5.

[0029] By designing a modular heat dissipation module 4, when the data acquisition device is used in high-temperature weather or in a high-temperature environment, the heat dissipation module 4 can be added to better dissipate heat from the internal circuit board 2, preventing high temperatures from reducing its performance and improving safety. At the same time, after adding the heat dissipation module 4, the device can also be hung up for use, expanding the scope of installation applicability.

[0030] The second embodiment differs from the first embodiment in that: the heat dissipation module 4 includes a vent box 41 that is snapped into the end of the outer shell 1. The vent pipes are an inlet pipe 42 and an outlet pipe 43 that rotatably pass through the left and right sides of the back of the vent box 41. Both the inlet pipe 42 and the outlet pipe 43 are L-shaped, and their outer ends are covered with filters 44. A filter cotton 45 is inserted inside the vent box 41 at the front of the inlet pipe 42. A miniature fan 46 is snapped into the vent box 41 at the right side of the filter cotton 45. An arc-shaped partition 47 is integrally injection molded inside the vent box 41 at the right side of the miniature fan 46. A miniature fan 46 is also inserted into the bottom of the vent box 41 at the right side of the miniature fan 46. A heat dissipation coil 48 is connected between the fan 46 and the arc-shaped partition 47 through a conical opening. The other end of the heat dissipation coil 48 passes through the bottom right side of the vent box 41 and connects to the front end of the air outlet pipe 43. The bottom rear side of the vent box 41 extends downward to form a fixing plate 49. Multiple sections of the heat dissipation coil 48 are fixed to the surface of the fixing plate 49 by fixing buckles. A plug 410 is installed through the middle of the bottom of the vent box 41. The top of the plug 410 is electrically connected to the miniature fan 46 through a wire. The top of the circuit board 2 is soldered with a socket corresponding to the plug 410. When installing the heat dissipation module 4, the plug 410 is inserted into the socket to connect the circuit board 2 to the miniature fan 46 for power supply.

[0031] The heat dissipation module 4 adopts air-cooled heat dissipation, using a disc-shaped bent copper tube for heat absorption. The structure is compact and does not affect the installation of the circuit board 2, which is conducive to its long-term use. In addition, the heat dissipation module 4 has a filter structure in the air passage to prevent internal dirt. At the same time, the heat dissipation module 4 has a hanging function by using the hook-shaped air inlet pipe 42 and air outlet pipe 43, which eliminates the need for additional hooks. Furthermore, the outer ends of the air inlet pipe 42 and air outlet pipe 43 face downwards to prevent rainwater from entering, allowing it to be used outdoors.

[0032] The third embodiment differs from the first embodiment in that: magnetic blocks 6 are embedded and fixedly connected to the four corners of the back of the outer shell 1, which are used to magnetically attach the outer shell 1 to the surface of the iron equipment shell.

[0033] By installing a magnet 6 on the back of the outer casing 1, the device has a magnetic installation function even when the heat dissipation module 4 is not installed, and it also has an auxiliary stabilizing effect when the heat dissipation module 4 is installed, making installation more convenient.

[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0035] When the heat dissipation module 4 is working, the micro fan 46 draws air from the left side, causing the air intake pipe 42 to draw in outside air, which is then filtered through the filter screen 44 and the filter cotton 45 in sequence, and then discharged to the right side by the micro fan 46. After being guided by the arc-shaped partition 47, it is discharged downward into the heat dissipation coil 48, and then carries away the heat inside the outer casing 1 and is discharged.
