Description

Technical Field

[0001] This utility model relates to the field of fire monitoring device technology, and in particular to an installation structure for an electrical fire monitoring device. Background Technology

[0002] Electrical cabinets are crucial facilities in electrical applications, used to install various electrical components. During their use, electrical components can malfunction or undergo pyrolysis, which can easily lead to fires within the electrical cabinet. According to fire statistics in my country in recent years, electrical fires account for approximately 27% of all fires annually. Therefore, monitoring and early warning systems for electrical cabinets are extremely important.

[0003] An electrical fire monitoring device is a box-like structure installed inside an electrical cabinet and integrating various sensing facilities such as PM sensors, gas sensors, and temperature sensors. It monitors environmental changes inside the electrical cabinet in real time through various sensing devices. For example, the temperature sensor monitors temperature changes inside the electrical cabinet. When the temperature inside the electrical cabinet exceeds the safety limit, it reports to the processor, which then sends a command to the alarm to activate the alarm.

[0004] However, when current electrical fire monitoring devices (hereinafter referred to as monitoring devices) are installed in electrical cabinets, the cabinets need to have pre-set mounting holes to fix the monitoring devices. After the monitoring devices are installed, due to the increase in electrical components inside the electrical cabinet or the influence of factors such as line pulling (e.g., when upgrading equipment in a factory, new electrical components need to be added or replaced), in order to avoid the monitoring devices affecting the layout of the lines and electrical components, it is necessary to change the installation position of the monitoring devices. However, if the position of the monitoring devices is changed now, new mounting holes need to be drilled in the electrical cabinet, and the monitoring devices need to be disassembled and reinstalled. Therefore, it is inconvenient to use.

[0005] In conclusion, improvements need to be made to the existing monitoring devices. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrical fire monitoring device, which aims to solve the problems mentioned in the background technology.

[0007] The technical solution of this utility model is implemented as follows: An electrical fire monitoring device includes a housing, on which a circuit board structure equipped with a sensor is detachably connected. The housing is detachably connected to an electrical cabinet via a mounting structure, wherein the mounting structure includes:

[0008] A fixed base plate has at least two threaded holes and at least two slides;

[0009] A sliding base plate has at least two limiting structures that are slidably connected in each slide rail, and is used for housing mounting;

[0010] The limiting structure has a pressing end, and the sliding base plate is loosened or fixed by adjusting the separation or contact between the pressing end and the inner wall of the slide.

[0011] When the sliding base plate can move on the slide, the housing can be placed on the fixed base plate in any orientation.

[0012] Preferably, the slide rail consists of a first slide rail and a second slide rail coaxially disposed on a fixed base plate, and both the first slide rail and the second slide rail include:

[0013] The groove is recessed on the fixed base plate;

[0014] The limiting groove is recessed on the wall of the sliding groove.

[0015] Preferably, the limiting structure includes:

[0016] The limiting shaft is integrally formed on the sliding base plate and can slide within the slide rail;

[0017] A shaft cavity is formed within a limiting shaft, and at least one end extends axially and passes through one end of the limiting shaft;

[0018] The movable opening is located on the outer wall of the limiting shaft and communicates with the shaft cavity. The movable opening radially penetrates the side wall of the limiting shaft.

[0019] The movable shaft moves axially within the shaft cavity;

[0020] The abutment block is slidably connected to the limiting shaft and can slide radially at the movable opening position;

[0021] The movable shaft is provided with a compression spring between it and the shaft cavity, and the movable shaft has at least a compression part with a diameter that gradually increases axially; the abutment block can be guided by the compression part and cause one end of the abutment block to abut against the inner wall of the slide.

[0022] Preferably, a first anti-slip rubber pad is fixedly connected to one end of the abutment block.

[0023] Preferably, the inner wall of the movable opening is provided with a groove, the abutting block has a limiting block that moves within the groove, and a limiting spring is provided between the limiting block and the groove wall.

[0024] Preferably, the two ends of the shaft cavity are respectively axially penetrated by the limiting shaft, and a second anti-slip rubber pad is fixedly connected to one end of the movable shaft.

[0025] Preferably, a nut structure is detachably connected to the limiting shaft, wherein the nut structure includes:

[0026] The nut is threadedly connected to the limiting shaft;

[0027] A spring cavity is formed on the nut and is used for mounting the compression spring;

[0028] The nut has an opening coaxial with the shaft cavity and through which one end of the movable shaft passes. The movable shaft has a limiting piece that moves within the spring cavity. The two ends of the compression spring abut against the spring cavity and the limiting piece, respectively.

[0029] Preferably, the fixed base plate has a notch that communicates with the slide rail, and a cover is engaged at the notch. When the cover is opened, the limiting structure can disengage from the notch and slide rail.

[0030] This utility model has at least the following beneficial effects:

[0031] 1. During installation, this utility model only requires drilling threaded holes on the electrical cabinet that are compatible with the fixing base plate, and fixing the fixing base plate to the electrical cabinet to complete the installation of the monitoring device. Furthermore, since the fixing base plate is provided with a slide rail, when it is necessary to adjust the position of the monitoring device, it can be moved on the fixing base plate by sliding the base plate, thereby adjusting the position of the monitoring device (housing) in the electrical cabinet, so that the housing avoids the traction line. Therefore, when changing the position of the housing, it is not necessary to drill mounting holes on the electrical cabinet again.

[0032] 2. When adjusting the sliding base plate, the movable shaft is pulled up to separate the abutment block from the slide rail and then the sliding base plate can be moved smoothly. When fixing, the movable shaft is released and the compression spring drives the abutment block to contact the slide rail through the movable shaft, thereby fixing the sliding base plate.

[0033] 3. The movable shaft of this utility model is also detachably connected to the limiting shaft through a nut structure, which facilitates the replacement of the movable shaft and makes subsequent maintenance convenient.

[0034] 4. The notch provided in the fixed base plate of this utility model allows the sliding base plate to be removed from the fixed base plate, so that the fixed base plate does not need to be disassembled when replacing the monitoring device. Attached Figure Description

[0043] 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.

[0044] Example 1:

[0045] like Figure 1 As shown, in the prior art, the housing 10 can be installed on the cabinet door 11 of the electrical cabinet 1, such as... Figure 1 The right-side electrical cabinet 1 has its housing 10 fixed to the cabinet door 11 by fasteners 12. However, when electrical components (such as control box 13) inside the electrical cabinet are installed, the housing will conflict with the electrical components. If the electrical cabinet is full of wiring, the area available for housing installation will be further reduced. Since the electrical components inside the electrical cabinet need to be adjusted according to the company's development process and the upgrading and replacement of factory facilities, it is difficult to set a fixed position for the housing to be placed for a long time.

[0046] Another reason is that the various electrical structures inside the electrical cabinet have different responsibilities, and the loads and failure rates they bear are also different. Therefore, in order for the monitoring device to detect fire risks as soon as possible, the monitoring device will be installed close to the electrical structures with higher failure rates and risks, so the position of the casing also needs to be adjusted.

[0047] Therefore, due to various reasons, multiple mounting holes 14 are usually provided on the cabinet door of the electrical cabinet. When the position of the housing needs to be adjusted, the housing can be disassembled and installed in other mounting hole 14 positions to adapt to the layout inside the electrical cabinet and actual use. Therefore, it is inconvenient to use.

[0048] like Figure 1 Left side electrical cabinet and Figures 2-4 As shown, this embodiment provides an electrical fire monitoring device, including a housing 10.

[0051] The sliding base plate 24 has at least two limiting structures that are slidably connected in each slide rail, and is installed in the housing 10;

[0052] The limiting structure has a pressing end, and the sliding base plate 24 is loosened or fixed by adjusting the separation or contact between the pressing end and the inner wall of the slide.

[0053] When the sliding base plate 24 can move on the slide, the housing 10 can be placed on the fixed base plate in any orientation.

[0054] In this embodiment: the slide rail is composed of a first slide rail 201 and a second slide rail 202 coaxially disposed on the fixed base plate 20, and both the first slide rail 201 and the second slide rail 202 include:

[0055] The groove 30 is recessed on the fixed base plate 20;

[0056] The limiting groove 31 is recessed on the groove wall of the sliding groove 30.

[0057] In this embodiment: the limiting structure includes:

[0060] The movable opening 42 is located on the outer wall of the limiting shaft 40 and communicates with the shaft cavity 41. The movable opening 42 radially penetrates the side wall of the limiting shaft 40.

[0061] The movable shaft 43 is axially movable within the shaft cavity 41;

[0062] The abutment block 44 is slidably connected to the limiting shaft 40 and can slide radially at the movable opening 42;

[0063] Wherein, a compression spring 45 is provided between the movable shaft 43 and the shaft cavity 41, and the movable shaft 43 has at least a compression part 43a with a diameter that gradually increases axially; the abutment block 44 can be guided by the compression part 43a and cause one end of the abutment block 44 to abut against the inner wall of the slide (the inner wall of the limiting groove).

[0064] In this embodiment, a first anti-slip rubber pad 44a is fixedly connected to one end of the abutment block 44 away from the movable shaft 43.

[0065] In this embodiment, the inner wall of the movable opening 42 is provided with a groove 50, the abutment block 44 has a limiting block 44b that is movable within the groove 50, and a limiting spring 52 is provided between the limiting block 44b and the groove wall of the groove 50.

When adjusting the position, the movable shaft is pulled up, causing one end of the movable shaft to separate from the slide rail. The abutment block is also retracted into the movable opening by the limiting spring. After the movable shaft and the abutment block are separated from the slide rail, the limiting shaft can slide freely in the slide rail and adjust the position of the sliding base plate. After the position is adjusted, the movable shaft is released. The movable shaft is driven by the compression spring to contact the slide rail and drive the abutment block to contact the limiting groove, thereby fixing the limiting shaft and fixing the sliding base plate in the designated position of the fixed base plate, thus completing the adjustment of the housing.
