Description

Technical Field

[0001] This utility model relates to the field of infrared sensor installation technology for low-voltage switchgear, and in particular to a multi-node infrared sensor installation structure for low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear is a complete set of electrical equipment used in power systems to receive, distribute, and control low-voltage electrical energy. It is mainly used in AC 50Hz (or 60Hz) power distribution systems with a rated voltage of 380V (or 400V, 690V, etc.) and below. It is widely used in industrial, commercial, civil buildings, municipal engineering and other fields. It is one of the key equipment in the power transmission and distribution process. The safe and stable operation of low-voltage switchgear is of paramount importance. In order to monitor the temperature changes inside the low-voltage switchgear in real time and detect potential faults in time, infrared sensors are usually installed inside the low-voltage switchgear to detect the temperature inside the equipment cabinet in real time.

[0003] However, the existing equipment has the following shortcomings: When installing infrared sensors, the existing equipment generally uses bolts to install the infrared sensors. The installation and removal of bolts require the use of tools, which is too cumbersome and causes low installation efficiency for users.

[0004] Therefore, we propose a multi-node infrared sensor installation structure for low-voltage switchgear to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing technologies generally use bolts to install infrared sensors, which is too cumbersome to install and remove, resulting in low installation efficiency for users. Therefore, this utility model proposes a multi-node infrared sensor installation structure for low-voltage cabinets.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-node infrared sensor installation structure for low-voltage cabinets, comprising a cabinet body, a cabinet door, a mounting plate, a plug plate, an infrared sensor, and an installation device. The cabinet door is rotatably connected to the surface of the cabinet body. The plug plate is fixedly connected to the surface of the mounting plate. The infrared sensor is installed inside the plug plate. The plug plate is inserted into the interior of the cabinet body. The installation device is installed inside the mounting plate. The installation device includes a connecting block and a plug rod. The connecting block is fixedly connected to the outer surface of the cabinet body. The surface of the connecting block has a hole. The plug rod is inserted into the hole. The side of the mounting plate has a sliding hole. The surface of the plug rod is fixedly connected to a sliding rod.

[0007] Furthermore, the slide rod is slidably connected inside the slide hole, and a fixing block is fixedly connected to the end of the slide rod away from the insertion rod. By setting the slide rod, the insertion rod can be limited to move, reducing the situation where the insertion rod is difficult to move during use.

[0008] Furthermore, a first spring is sleeved and connected to the surface of the slide rod.

[0009] Furthermore, one end of the first spring is fixedly connected to the surface of the fixing block, and the end of the first spring away from the fixing block is fixedly connected to the surface of the mounting plate. The first spring is provided to facilitate the application of a restoring force to the slide rod.

[0010] Furthermore, a replacement device is fixedly provided on the surface of the infrared sensor. The replacement device includes a limiting groove and a connecting plate. The connecting plate is fixedly connected to the outer surface of the infrared sensor. The limiting groove is formed on the surface of the mounting plate. A groove is formed on the surface of the connecting plate. A moving rod is fixedly connected inside the groove. A locking plate is slidably connected to the surface of the moving rod. The locking plate engages with the inside of the limiting groove. By setting the locking plate, the infrared sensor can be limited, reducing the difficulty of limiting the infrared sensor during use.

[0011] Furthermore, a second spring is sleeved and connected to the surface of the movable rod.

[0012] Furthermore, one end of the second spring is fixedly connected to the surface of the card plate, and the other end of the second spring away from the card plate is fixedly connected to the inside of the groove. The second spring is provided to facilitate the application of a reset force to the card plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an installation device, the mounting plate and insert plate are effectively connected and installed to the inside of the cabinet, which plays a role in quickly installing infrared sensors.

This installation device enables rapid installation of infrared sensors and improves the installation efficiency for users.

[0015] 2. In this utility model, by setting a replacement device, the infrared sensor can be effectively replaced, which can quickly replace the infrared sensor.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a multi-node infrared sensor installation structure for low-voltage cabinets, including cabinet body 1, cabinet door 2, mounting plate 3, insert plate 4, infrared sensor 5 and installation device 6. The cabinet door 2 is rotatably connected to the surface of the cabinet body 1, the insert plate 4 is fixedly connected to the surface of the mounting plate 3, the infrared sensor 5 is installed inside the insert plate 4, and the insert plate 4 is inserted and connected to the inside of the cabinet body 1.

[0025] Cabinet 1 is made of cold-rolled steel plate with electrostatic spraying treatment, which is rust-proof and has good insulation; Cabinet door 2 is a tempered glass door, which can observe the internal situation and has a protective function; Mounting plate 3 is an insulating plastic plate with high strength; Insert plate 4 is a metal plate; Infrared sensor 5 is a high-precision temperature sensor with fast response speed.

[0026] The specific setup and function of the installation device 6 and the replacement device 7 will be described in detail below.

[0027] In this embodiment: the installation device 6 is installed inside the installation plate 3. The installation device 6 includes a connecting block 61 and a plug rod 62. The connecting block 61 is fixedly connected to the outer surface of the cabinet 1. The surface of the connecting block 61 is provided with a plug hole 63. The plug rod 62 is inserted and connected inside the plug hole 63. The side of the installation plate 3 is provided with a sliding hole 65. The surface of the plug rod 62 is fixedly connected with a sliding rod 64.

[0028] Specifically, the slide rod 64 is slidably connected inside the slide hole 65, and a fixing block 66 is fixedly connected to the end of the slide rod 64 away from the insertion rod 62.

[0029] In this embodiment, by setting the slide bar 64, the insertion rod 62 can be limited to move, reducing the difficulty of limiting the movement of the insertion rod 62 during use.

[0030] Specifically, a first spring 67 is sleeved and connected to the surface of the slide rod 64.

[0031] Specifically, one end of the first spring 67 is fixedly connected to the surface of the fixing block 66, and the other end of the first spring 67 away from the fixing block 66 is fixedly connected to the surface of the mounting plate 3. The first spring 67 is provided to facilitate the application of a restoring force to the slide rod 64.

[0032] In this embodiment: A replacement device 7 is fixedly installed on the surface of the infrared sensor 5. The replacement device 7 includes a limiting groove 71 and a connecting plate 72. The connecting plate 72 is fixedly connected to the outer surface of the infrared sensor 5. The limiting groove 71 is opened on the surface of the mounting plate 3. A groove 74 is opened on the surface of the connecting plate 72. A moving rod 73 is fixedly connected inside the groove 74. A locking plate 75 is slidably connected to the surface of the moving rod 73. The locking plate 75 is engaged with the inside of the limiting groove 71.

[0033] In this embodiment, by setting the card plate 75, the infrared sensor 5 can be limited, reducing the difficulty of limiting the infrared sensor 5 during use.

[0034] Specifically, a second spring 76 is sleeved and connected to the surface of the moving rod 73.

[0035] Specifically, one end of the second spring 76 is fixedly connected to the surface of the card plate 75, and the other end of the second spring 76 away from the card plate 75 is fixedly connected to the inside of the groove 74. The second spring 76 is provided to facilitate the application of a reset spring force to the card plate 75.

[0036] Working principle: When using the equipment, the user installs the infrared sensor 5 inside the cabinet 1. The infrared sensor 5 is distributed at different nodes in the cabinet 1. The infrared sensor 5 monitors the temperature inside the cabinet 1 in real time. When installing the infrared sensor 5, the mounting plate 3 and the insert plate 4 are connected to the inside of the cabinet 1. When the insert plate 4 is inserted into the inside of the cabinet 1, pulling the insert rod 62 moves the sliding rod 64 inside the mounting plate 3. When the sliding rod 64 moves, it compresses the first spring 67 to generate elastic force, fully engaging the insert plate 4 with the inside of the cabinet 1. Then, the constraint of the insert rod 62 is released, and the first spring 67 releases its elastic force. When the sliding rod 64 moves during the reset, the movable insert rod 62 is inserted into the connecting block 61 on the surface of the cabinet 1, which is then limited. By setting the installation device 6, the mounting plate 3 and the insert plate 4 are effectively connected and installed to the inside of the cabinet 1, which plays a role in quickly installing the infrared sensor 5. This reduces the need for bolts to install the infrared sensor 5 in existing equipment, which generally requires tools for bolt installation and removal. The use of tools is too cumbersome and results in low installation efficiency for users. This installation device 6 enables quick installation of the infrared sensor 5 and improves the installation efficiency for users.

[0037] When the infrared sensor 5 is replaced within the mounting plate 3, the user presses the locking plate 75. The locking plate 75 moves on the surface of the moving rod 73. As the locking plate 75 moves, it causes the second spring 76 to deform and generate elastic force. Subsequently, the locking plate 75 disengages from the limiting groove 71 on the surface of the mounting plate 3, and the infrared sensor 5 is released from its restraint. The infrared sensor 5 is then pulled out of the mounting plate 3 for replacement. By setting up the replacement device 7, the infrared sensor 5 can be replaced effectively, achieving the function of quickly replacing the infrared sensor 5. This reduces the difficulty of detecting different positions inside the cabinet 1 when the infrared sensor 5 is generally fixedly connected inside the mounting plate 3 in the existing equipment. This replacement device 7 realizes the replacement of the infrared sensor 5, facilitates the quick replacement of the position of the infrared sensor 5, and improves the practicality of the equipment.

[0038] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
