Description

Technical Field

[0001] This utility model relates to the technical field of water treatment control cabinets, specifically a water treatment control cabinet with temperature detection function. Background Technology

[0002] The water treatment control cabinet is a core electrical device in a water treatment system. It is primarily used to centrally install and control water pumps, valves, sensors, PLCs (Programmable Logic Controllers), and various electrical components, thereby achieving automated monitoring and management of the water treatment process. During operation, the internal electrical components generate heat. If the internal temperature of the control cabinet is too high, it may cause performance degradation of the electrical components, accelerated aging, or even equipment failure, affecting the stability and reliability of the entire water treatment system. Therefore, temperature monitoring inside the control cabinet is crucial.

[0003] In existing technologies, temperature sensors inside control cabinets are typically bolted directly to the cabinet's inner wall or mounting brackets. This makes the process cumbersome when sensors need maintenance, calibration, or replacement. Maintenance personnel must use specialized tools to loosen the bolts to remove the sensors, which is time-consuming and inconvenient in the confined space of the cabinet, reducing maintenance efficiency. Furthermore, frequent disassembly and reassembly can cause bolt stripping or wear on the mounting holes, affecting the reliability of the fixation.

[0004] Therefore, we propose a water treatment control cabinet with temperature detection function. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a water treatment control cabinet with temperature detection function. By creating a plug-in and self-locking snap-fit ​​structure, it replaces the traditional bolt fixing, fundamentally solving the problems of inconvenient disassembly and assembly of temperature sensors and low maintenance efficiency, and can effectively solve the problems in the background technology.

[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water treatment control cabinet with temperature detection function, including a cabinet body and a cabinet door. A wall-mounted temperature sensor is provided on the inner wall of the cabinet door. An installation plate is fixedly installed on the outer surface of the rear end of the wall-mounted temperature sensor. Fixing blocks are provided at both ends of the installation plate. Insertion blocks are fixedly installed on the outer surfaces of both ends of the installation plate. An insertion groove is opened on the outer surface of the fixing block near the installation plate. A bottom support block is fixedly installed at the bottom of the insertion groove. A snap-fit ​​structure is provided on the upper part of the inner side of the insertion groove. The snap-fit ​​structure includes an installation groove, a limiting slide groove, a movable block, a limiting slider, an upper inclined wedge, a through groove, a limiting block, and a compression spring. The installation groove is opened on the upper part of the inner side of the insertion groove, and the limiting slide groove is opened on the upper and lower sides of the installation groove.

[0007] Preferably, there are two sets of fixing blocks, and the mounting plate is inserted between the two sets of fixing blocks.

[0008] Preferably, the outer wall of the plug block and the plug slot are in a plug-in fit.

[0009] Preferably, the outer wall of the movable block and the mounting groove are in a sliding fit, the upper inclined wedge is fixed on the outer surface of the movable block away from the mounting groove, the limiting slider is fixed on the outer surface of the upper and lower ends of the movable block away from the upper inclined wedge, the outer wall of the limiting slider and the limiting groove are in a sliding connection, and the outer walls of the movable block and the upper inclined wedge are in a sliding connection with the mounting groove.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a water treatment control cabinet with temperature detection function, which has the following beneficial effects: 1. This water treatment control cabinet with temperature detection function achieves rapid installation and removal of wall-mounted temperature sensors through the plug-in cooperation between plug blocks and plug slots, and the automatic locking and releasing of the snap-fit ​​structure. During installation, simply align the plug blocks on both sides of the mounting plate with the plug slots and insert them; the snap-fit ​​will be automatically completed under the action of the compression spring. During removal, simply press the upper inclined wedge block; after the upper inclined wedge block enters the mounting slot, the limit will be released, and the wall-mounted temperature sensor can be pulled upwards.

[0013] 2. This water treatment control cabinet with temperature detection function uses an upper inclined wedge block to hold the upper surface of the plug block under the action of a spring, while the bottom of the plug block is supported by a bottom support block, forming a two-way limit, which effectively prevents the sensor from loosening and falling off due to vibration or accidental collision.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, this utility model discloses a water treatment control cabinet with temperature detection function, comprising a cabinet body 1 and a cabinet door 2 hinged to the front of the cabinet body 1. Two sets of fixing blocks 5 are bolted to the inner wall of the cabinet door 2. A mounting plate 4 is positioned between the two sets of fixing blocks 5, and a wall-mounted temperature sensor 3 is fixedly mounted on the front of the mounting plate 4. Insertion blocks 6 are fixedly mounted on the outer surfaces of the left and right ends of the mounting plate 4. An insertion groove 7, matching the shape and size of the insertion block 6, is provided on the side of the fixing block 5 closest to the mounting plate 4, allowing for a plug-in fit between the outer wall of the insertion block 6 and the insertion groove 7. A bottom support block 8 is fixedly mounted at the bottom of the insertion groove 7 to support the inserted insertion block 6.

[0021] A locking structure for locking the plug-in block 6 is provided on the upper part of the inner side of the plug-in groove 7. This locking structure includes a mounting groove 9 formed on the upper part of the inner side of the plug-in groove 7, and limiting grooves 10 formed on the upper and lower sides of the mounting groove 9. A movable block 11 is disposed within the mounting groove 9, and its outer wall is slidably fitted with the mounting groove 9. Limiting sliders 12 are fixed to the outer surfaces of the upper and lower ends of the movable block 11 (the end furthest from the upper inclined wedge block 13). The outer wall of the limiting slider 12 is slidably connected to the limiting groove 10, thereby limiting the movement trajectory of the movable block 11 and preventing it from dislodging. An upper inclined wedge block 13 is fixed to the outer surface of the movable block 11 at the end furthest from the bottom of the mounting groove 9. The end of the upper inclined wedge block 13 furthest from the mounting groove 9 extends into the interior of the plug-in groove 7, forming a guide slope inclined towards the opening of the plug-in groove 7. The outer walls of both the movable block 11 and the upper inclined wedge block 13 are slidably connected to the mounting groove 9.

[0022] A through groove 14 is formed on the outer surface of the front end of the movable block 11, extending through its outer surface of the rear end. A fixed limiting block 15 passes through the through groove 14, and the rear end of the limiting block 15 is fixed inside the mounting groove 9. A compression spring 16 is fixed between the outer surface of the limiting block 15 near the upper inclined wedge 13 and the inner surface of the through groove 14 near the upper inclined wedge 13. Therefore, the movable block 11 is elastically connected to the limiting block 15 through the compression spring 16, causing the upper inclined wedge 13 to tend to extend into the insertion groove 7 under normal conditions due to the spring force.

[0023] It should be noted that this utility model is a water treatment control cabinet with temperature detection function. The cabinet body 1 and cabinet door 2 described in this document are both existing technologies and can be effectively understood by those skilled in the art. Specific details will not be elaborated further. A wall-mounted temperature sensor 3 and fixing blocks 5 are provided. There are two sets of fixing blocks 5, located at the left and right ends of the wall-mounted temperature sensor 3, and the fixing blocks 5 are fixed to the inner wall of the cabinet door 2 by bolts.

[0024] When installing the wall-mounted temperature sensor 3, the operator holds the mounting plate 4 and aligns the plug-in blocks 6 on both sides with the plug-in slots 7 on the fixing block 5. Then, the plug-in blocks 6 are inserted vertically downwards from above the plug-in slots 7. During insertion, the bottom of the plug-in block 6 first contacts the guide slope of the upper inclined wedge block 13. Continuing to apply downward pressure, the plug-in block 6, through the action of the inclined surface, generates a force that pushes the upper inclined wedge block 13 into the mounting groove 9. This force causes the upper inclined wedge block 13 and the movable block 11 to slide inwards along the mounting groove 9. As the movable block 11 moves, its through slot 14 slides along the fixed limiting block 15, while the compression spring 16 is compressed, storing energy and deforming. When the plug-in block 6 is fully inserted and its bottom rests on the bottom support block 8, the upper surface of the plug-in block 6 just passes over the end of the upper inclined wedge block 13. At this point, since the plug block 6 no longer presses against the inclined surface, the compressed spring 16 releases its elastic force, pushing the movable block 11 and the upper inclined surface wedge 13 to reset outward, so that the end of the upper inclined surface wedge 13 is stuck on the upper surface of the plug block 6, thereby firmly locking the plug block 6 in the plug groove 7 and completing the quick installation.

[0025] When the wall-mounted temperature sensor 3 needs to be disassembled for maintenance or replacement, the maintenance personnel only need to press the exposed inclined surface of the upper inclined wedge 13 inward (towards the mounting groove 9) by hand. The upper inclined wedge 13 drives the movable block 11 to compress the spring 16 and move into the mounting groove 9 until the end of the upper inclined wedge 13 is completely out of the insertion groove 7 and no longer in contact with the upper surface of the insertion block 6. At this time, the limit above the insertion block 6 is released, and the operator can lift the mounting plate 4 along with the wall-mounted temperature sensor 3 upward, so that the insertion block 6 can be pulled out of the insertion groove 7, achieving quick disassembly. The whole process requires no tools and is simple and quick.
