Description

Technical Field

[0001] The utility model relates to the technical field of fire monitoring, in particular to an electrical fire monitoring device. Background Art

[0002] Electrical equipment has become an indispensable component of our daily lives. According to relevant statistics, electrical fires account for approximately 30% of all fires, ranking first among all fire types. Therefore, to ensure the safe use of electrical equipment, electrical fire monitoring systems are gaining increasing attention and application, becoming a crucial component of fire protection electrical design. Electrical fires are a common type of fire, and they can be caused by a variety of factors, such as aging insulators, ground faults, and power short circuits. Power short circuits are the most common cause. Most power short circuits that cause electrical fires are caused by gradual power failures, resulting in leakage. Preventing electrical fires requires accurate monitoring of leakage current from short circuits. The installation of relevant detection devices and monitoring systems monitors the current in the surrounding dielectric or on the surface of the insulator to prevent electrical fires.

[0003] In the existing technology, there are some deficiencies in the installation of air switches and detector accessories inside electrical fire monitoring equipment. For example, during installation, screws are needed to fix the air switches, detectors and other structures on the rail frame, and often several screws are required to fix them relatively firmly, which is more cumbersome during the installation and disassembly process.

[0004] In existing electrical fire monitoring equipment, a detector is used to disconnect the probe from the power transmission line to measure the temperature of the wire. When the warning temperature is reached, an alarm is issued. Tape or glue is usually used to fix the sensor, but this method may cause the glue to adhere to the surface of the temperature sensor and the wire, affecting the measurement accuracy. External factors such as dust and moisture may affect the performance of the sensor and the actual value detected by the sensor. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides an electrical fire monitoring device which has the advantages of easy installation and protection detection, and solves the problems raised by the above-mentioned background technology.

[0006] The utility model provides the following technical solution: an electrical fire monitoring device, comprising a box body, a box door movably installed on one side of the box body, a sealing ring movably installed on one side of the box body, two rails evenly fixedly installed in a linear array on the inner wall of the box body, air switches evenly and movably installed in a linear array inside the upper rails, an air switch and a detector movably installed inside the lower rails, an electric wire fixedly connected to the bottom of the air switch adjacent to the detector, and the other end of the electric wire is located inside the sealing ring.

[0007] Through the above-mentioned structural setting, the air switch and detector can be quickly installed inside the box, which is more convenient when disassembling for replacement or maintenance. By arranging a wax ring and a detection ring on the outer ring of the wire, the wire can avoid long-term contact with the detection ring during normal temperature power transmission to accelerate aging or unclear sensing. The wax ring protects the detection ring and also achieves the effect of uniform temperature transmission, so that the temperature measured by the detection ring is more accurate.

[0008] Preferably, the cross section of the rail frame is an elliptical shape with a notch, the surface of the rail frame is symmetrically provided with mounting grooves, and the back side of the rail frame is linearly and evenly provided with limiting holes between the mounting grooves.

[0009] Through the above-mentioned structural setting, the cross section is set to an elliptical shape with a notch, which makes it easy for the air switch or detector to be moved inside the rail frame and is not limited to a certain position. After the installation groove and the limit hole are set, the installation workers are prevented from using screws for tightening.

[0010] Preferably, a vertical circular groove and a horizontal circular groove are provided inside the air switch and the detector, wherein the vertical circular groove is provided on a side close to the limiting hole, and the horizontal circular groove is provided on a side.

[0012] Through the above-mentioned structural setting, by pressing the unlocking column A, the end of the unlocking column A squeezes and contracts the clamping column A, so that the spring A is compressed and enters the interior of the rail frame through the installation groove. After selecting a fixed position, release the hand pressing the unlocking column A, so that the clamping column A is squeezed outward by the spring A, and the clamping column A is stuck in the limiting hole to achieve position fixing.

[0013] Preferably, the bottom of the detector is fixedly connected to a detection wire, the detector is provided with a protective cover located on the outer ring of the wire, a detection ring is slidably sleeved inside the protective cover, the detection ring is connected to the detection wire, the inner ring of the detection ring is located on the outer ring of the wire and is fixedly sleeved with a wax ring, and the wax ring is made of medium-temperature wax as a whole.

[0014] Through the above-mentioned structural setting, by setting the wax ring, when the temperature of the wire rises, the wax ring will melt evenly, and the melted temperature will be evenly transmitted to the detection ring, so that the heat contacted by the detection ring is more uniform, and the value measured by the detection ring is more accurate. By setting a protective cover on the outer ring of the detection ring, the detection ring is protected from intrusion from the external environment, such as pollution by dust.

[0015] Preferably, a clamping column B is slidably installed inside the vertical circular groove of the detector, a triangular groove B is provided on the outer ring of the clamping column B, a spring B is fixedly connected between the end of the clamping column B and the inner wall of the vertical circular groove, an unlocking column B is slidably installed inside the horizontal circular groove of the detector, the triangular groove B is adapted to the end of the unlocking column B, and the clamping column B is adapted to the limiting hole.

[0016] Through the above-mentioned structural setting, by pressing the unlocking column B, the end of the unlocking column B squeezes and contracts the clamping column B, so that the spring B is compressed and enters the interior of the rail frame through the installation groove. After selecting the fixed position, release the hand pressing the unlocking column B, so that the clamping column B is squeezed outward by the spring B, and the clamping column B is stuck in the limiting hole to achieve position fixing.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The electrical fire monitoring equipment is easy to install by providing structures such as an air switch, a rail frame, and a detector. By pressing the unlocking column A, the end of the unlocking column A squeezes and contracts the clamping column A, so that the spring A is pressed and enters the interior of the rail frame through the installation groove. After selecting a fixed position, release the hand pressing the unlocking column A, so that the clamping column A is squeezed outward by the spring A, and the clamping column A is stuck in the limit hole to achieve position fixing. The installation method of the detector is roughly the same as that of the air switch. Through the above-mentioned structural setting, quick installation can be achieved, the installation time of workers is reduced, and the installation and disassembly are facilitated.

[0019] 2. The electrical fire monitoring equipment realizes protection of the detection ring by setting up detectors, protective covers, wax rings and other structures. The wax ring sleeved on the outer ring of the wire will be melted by the heat emitted by the wire. After the wax ring melts, the heat is evenly transferred to the detection ring wrapped around the outer ring, so that the temperature of the wire detected by the detection ring rises rapidly, making the temperature value detected by the detection ring more accurate.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 2 An electrical fire monitoring device includes a box body 1, a box door 11 is movably installed on one side of the box body 1, a sealing ring 12 is movably installed on one side of the box body 1, and two rail frames 2 are evenly fixedly installed on the inner wall of the box body 1 in a linear array. An air switch 3 is evenly and movably installed in a linear array inside the upper rail frame 2, and an air switch 3 and a detector 4 are movably installed inside the lower rail frame 2. The bottom of the air switch 3 adjacent to the detector 4 is fixedly connected to a wire 31, and the other end of the wire 31 is located inside the sealing ring 12.

[0029] By cooperating with each other in the structures of the present application, the air switch 3 and the detector 4 can be quickly installed inside the box 1, which is more convenient when disassembling for replacement or maintenance. By providing a wax ring 44 and a detection ring 43 on the outer ring of the wire 31, the wire 31 is prevented from being in contact with the detection ring 43 for a long time during normal temperature power transmission, which may accelerate aging or make the induction unclear. The wax ring 44 protects the detection ring 43 and also achieves the effect of uniform temperature transmission, so that the temperature measured by the detection ring 43 is more accurate.

[0030] See also Figure 1-Figure 3 The cross section of the rail frame 2 is an elliptical shape with a notch. The surface of the rail frame 2 is symmetrically provided with mounting grooves 21 . The back of the rail frame 2 is linearly and evenly provided with limiting holes 22 between the mounting grooves 21 .

[0031] By setting the cross section into an elliptical shape with a notch, the air switch 3 or the detector 4 can be easily moved inside the rail frame 2 and is not limited to a certain position. After the installation groove 21 and the limiting hole 22 are set, the installation workers are prevented from using screws for fastening, which reduces the installation time of the workers and achieves convenient installation.

[0032] See also Figure 1-Figure 5 A vertical circular groove and a horizontal circular groove are provided inside the air switch 3 and the detector 4, wherein the vertical circular groove is provided on the side close to the limiting hole 22, and the horizontal circular groove is provided on the side. A card column A32 is slidably installed inside the vertical circular groove of the air switch 3, and a triangular groove A321 is provided on the outer ring of the card column A32. A spring A322 is fixedly connected between the end of the card column A32 and the inner wall of the vertical circular groove. An unlocking column A33 is slidably installed inside the horizontal circular groove of the air switch 3, and the triangular groove A321 is adapted to the end of the unlocking column A33, and the card column A32 is adapted to the limiting hole 22.

[0033] By pressing the unlocking column A33, the end of the unlocking column A33 squeezes and contracts the clamping column A32, so that the spring A322 is compressed and enters the interior of the rail frame 2 through the installation slot 21. After selecting a fixed position, release the hand pressing the unlocking column A33, so that the clamping column A32 is squeezed outward by the spring A322, and the clamping column A32 is stuck in the limiting hole 22 to achieve position fixing.

[0034] See also Figure 1-Figure 3 The bottom of the detector 4 is fixedly connected to a detection wire 41. The detector 4 is located on the outer circle of the wire 31 and is provided with a protective cover 42. A detection ring 43 is slidably sleeved inside the protective cover 42. The detection ring 43 is connected to the detection wire 41. The inner circle of the detection ring 43 is located on the outer circle of the wire 31 and is fixedly sleeved with a wax ring 44. The wax ring 44 is made of medium-temperature wax as a whole. It can be switched to low-temperature wax or high-temperature wax according to the user's choice, and the selection is made according to the critical point of the temperature to be measured.

[0035] By providing the wax ring 44, when the temperature of the wire 31 rises, the wax ring 44 is evenly melted, and the melting temperature is evenly transmitted to the detection ring 43, so that the heat contacted by the detection ring 43 is more uniform, and the value measured by the detection ring 43 is more accurate. By providing the protective cover 42 on the outer ring of the detection ring 43, the detection ring 43 is protected from the intrusion of the external environment, such as pollution by dust.

[0036] See also Figures 1-6 A clamping column B45 is slidably installed inside the vertical circular groove of the detector 4, and a triangular groove B451 is opened on the outer ring of the clamping column B45. A spring B452 is fixedly connected between the end of the clamping column B45 and the inner wall of the vertical circular groove. An unlocking column B46 is slidably installed inside the horizontal circular groove of the detector 4, and the triangular groove B451 is adapted to the end of the unlocking column B46, and the clamping column B45 is adapted to the limiting hole 22.

[0037] By pressing the unlocking column B46, the end of the unlocking column B46 squeezes and contracts the clamping column B45, so that the spring B452 is compressed and enters the interior of the rail frame 2 through the installation slot 21. After selecting a fixed position, release the hand pressing the unlocking column B46, so that the clamping column B45 is squeezed outward by the spring B452, and the clamping column B45 is stuck in the limiting hole 22 to achieve position fixing.

[0038] Working principle: When installing the air switch 3, press the unlocking column A33 so that the end of the unlocking column A33 squeezes and contracts the clamping column A32, so that the spring A322 is compressed and enters the interior of the rail frame 2 through the installation slot 21. After selecting a fixed position, release the hand pressing the unlocking column A33, so that the clamping column A32 is squeezed outward by the spring A322, and the clamping column A32 is clamped into the limiting hole 22 to achieve position fixing. The installation method of the detector 4 is roughly the same as that of the air switch 3. The above structural setting can achieve quick installation and reduce the installation time of workers.

[0039] When monitoring the external temperature of the wire 31, when the current of the wire 31 is unstable and the temperature of the wire 31 rises rapidly, which may subsequently develop into a fire, the wax ring 44 sleeved on the outer ring of the wire 31 will be melted by the heat emitted by the wire 31. After the wax ring 44 melts, the heat is evenly transferred to the detection ring 43 wrapped around the outer ring, so that the detection ring 43 detects the rapid increase in the temperature of the wire 31, making the temperature detected by the detection ring 43 more accurate. By setting the protective cover 42, the detection ring 43 is protected from the intrusion and wear of the external environment, thereby increasing the service life of the detection ring 43.
