Description

Technical Field

[0001] This invention relates to the field of power distribution monitoring technology, and in particular to a power grid power distribution monitoring device. Background Technology

[0002] Currently, power grid distribution systems include distribution cabinets. These cabinets generate high-frequency vibrations and temperatures during power distribution, sometimes even leading to localized high temperatures. While fans are used to address heat dissipation, moisture from the air can still enter the cabinet. To monitor the power stability and temperature / humidity of the distribution cabinet in real time, a power distribution monitoring device with electrical connections needs to be installed on the outside of the cabinet. This monitoring device includes sensors and power stability detectors, and the electrical connections require tightening with bolts. However, current power distribution monitoring devices have the following drawbacks:

[0003] Traditional temperature and humidity monitoring is mostly passive and static, relying solely on sensors to naturally sense the temperature and humidity in the distribution cabinet. This can easily lead to localized high temperatures and damp areas in the distribution cabinet being difficult to capture, resulting in blind spots in monitoring and the potential for not detecting moisture and overheating in a timely manner.

[0004] Traditional cable conductive contact plates are flat and rigid. Due to the large variation in cable thickness and the round shape of the cable, the contact area between the cable and the power distribution monitoring device is small, which easily leads to poor contact. Tightening and loosening the bolts requires a wrench, making the operation of the cable connection point with the power distribution monitoring device cumbersome. In addition, the bolts are prone to loosening after vibration, which can easily lead to poor cable contact, and thus pose a risk of overheating and arcing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a power grid power distribution monitoring device that solves the problems of cumbersome operation due to bolt fixing of distribution cabinet monitoring devices, as well as the problem of unstable conductivity caused by easy loosening and displacement. Furthermore, it solves the problem of blind spots in the static monitoring of distribution cabinets by the power distribution monitoring device.

[0006] The objective of this invention is achieved as follows: A power grid power distribution monitoring device includes: a distribution cabinet, a power line extending outward from the left side of the distribution cabinet, a sturdy housing fixedly installed on the outside of the distribution cabinet, a fan and a detection sensor assembly fixedly installed inside the sturdy housing, and a drain pipe fixedly installed on the right side of the sturdy housing; an air outlet is provided on the left side of the distribution cabinet, the right side of the drain pipe is attached to the air outlet, and an air inlet is provided on the right side of the sturdy housing and communicates with it, the air inlet being located at the edge of the detection sensor assembly.

[0007] Furthermore, a docking shell and a positioning cylinder are fixedly provided on the left outer end face of the power distribution cabinet. A stabilizing groove is provided inside the docking shell, and a T-shaped plate is fixedly provided on the right side of the stabilizing shell. The right side of the T-shaped plate is inserted into the stabilizing groove.

[0008] Furthermore, a locking rod is inserted inside the positioning cylinder, and locking holes are provided inside the T-shaped plates of both the docking shell and the stabilizing shell. A support spring is installed on the outside of the locking rod, and the front side of the locking rod is inserted into the locking hole.

[0009] Furthermore, a protective shell is fixedly installed on the front side of the sturdy shell, and a positioning sleeve is fixedly installed on the outside of the power cord of the distribution cabinet. An annular groove is provided on its edge. A clamping groove is provided on the left and right sides of both the sturdy shell and the protective shell, and the clamping groove and the annular groove engage.

[0010] Furthermore, a detector integrated body is fixedly installed inside the stable housing. A positioning seat is fixedly installed on the front side of the detector integrated body. A sliding hole is opened inside the positioning seat. A sliding rod is inserted into the sliding hole. A pressure plate is fixedly installed at the bottom of the sliding rod. A support spring is installed on the outside of the sliding rod.

[0011] Furthermore, a first conductive plate is fixedly installed on the outer side of the positioning seat, and a second conductive plate is fixedly installed inside the first conductive plate. The power cord of the distribution cabinet extends between the second conductive plate and the clamping plate.

[0012] Furthermore, the second conductive plate has uniformly distributed bending grooves, and the first conductive plate and the second conductive plate are electrically connected.

[0013] Furthermore, a control panel is fixedly installed at the upper end of the sliding rod, and a sliding hole is opened at the bottom of the control panel. A positioning rod is inserted inside the hole, and a locking block is fixedly installed on the rear side of the positioning rod. A locking groove distributed vertically is opened at the corner of the positioning seat, and the locking block is engaged in the locking groove.

[0014] Furthermore, the upper end of the locking block is provided with an inclined surface, and a support spring is installed on the outer side of the positioning rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention sets up a fan and a diversion pipe to actively guide the airflow, continuously drawing airflow from inside the power distribution cabinet. The airflow is concentrated and passes through the detection sensor assembly, actively circulating and collecting the temperature and humidity in the power distribution cabinet, thus solving the problem of blind spots in traditional static monitoring.

[0017] This invention features a sliding rod and a clamping plate that automatically press down to hold the cable with the aid of a spring. A positioning rod and a locking block provide secondary locking of the clamping plate, forming a double vertical clamping and locking mechanism that prevents the cable from loosening even under prolonged vibration. A wave-shaped second conductive plate with its own elasticity adapts to power cables of different thicknesses, maintaining a tight conductive contact and preventing overheating, arcing, and power supply monitoring data distortion caused by loose connections or small contact areas. Lifting the control panel moves the clamping plate upwards, allowing for quick installation and removal of the power cable, reducing maintenance time for the power distribution monitoring device.

[0018] In addition, the power cord is quickly snapped into place from the front after the housing is secured. The protective housing is then automatically secured to the power cord after assembly, preventing it from shifting left or right. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1-10 The power grid power supply and distribution monitoring device shown includes: a distribution cabinet 100, a docking shell 110 and a positioning cylinder 120 are fixedly provided on the left outer end face of the distribution cabinet 100, a stabilizing groove is provided inside the docking shell 110, a T-shaped plate is fixedly provided on the right side of the stabilizing shell 310, the right side of the T-shaped plate is inserted into the stabilizing groove, the T-shaped plate and the stabilizing groove of the docking shell 110 are engaged with each other, and the stabilizing shell 310 can be quickly installed and positioned on the side of the distribution cabinet 100.

[0033] In this embodiment, a locking rod 200 is inserted inside the positioning cylinder 120. Locking holes are provided inside the T-shaped plates of the docking shell 110 and the stabilizing shell 310. A support spring is installed on the outside of the locking rod 200. The support spring pushes the front side of the locking rod 200 into the locking hole, quickly locking the stabilizing shell 310 to the outside of the distribution cabinet 100. The locking position of the locking rod 200 has a sliding stroke, which keeps the stabilizing shell 310 stable when the device vibrates during operation. Pulling the locking rod 200 backward to compress the spring can unlock the stabilizing shell 310. The disassembly and assembly of the stabilizing shell 310 is time-saving and labor-saving.

[0034] In this embodiment, a sturdy housing 310 is fixedly installed on the outside of the distribution cabinet 100. A fan 400 and a sensor assembly 500 are fixedly installed inside the sturdy housing 310. A drain pipe 330 is fixedly installed on the right side of the sturdy housing 310. An air outlet is opened on the left side of the distribution cabinet 100, and the right side of the drain pipe 330 is attached to the air outlet. An air inlet is opened on the right side of the sturdy housing 310 and communicates with it. The air inlet is located at the edge of the sensor assembly 500. The fan 400 and the drain pipe 330 form an air passage. When the fan 400 runs, it absorbs the airflow inside the distribution cabinet 100, allowing the airflow to pass through the sensor assembly 500 and then be discharged into the sturdy housing 310. During this process, the sensor assembly 500 monitors the temperature and humidity of the airflow in the distribution cabinet 100. The system monitors the temperature and humidity inside the distribution cabinet 100 in real time. If the temperature or humidity exceeds the standard, it promptly transmits the signal to the detector integrated body 610 to avoid safety hazards such as moisture and overheating of the distribution cabinet 100. A protective shell 320 is fixedly installed on the front side of the stable shell 310. A power cord extends outward from the left side of the distribution cabinet 100, and a positioning sleeve is fixedly installed on the outside of the power cord. An annular groove is opened on its edge. A clamping groove is opened on the left and right sides of both the stable shell 310 and the protective shell 320. After the stable shell 310 and the protective shell 320 are spliced ​​together, the clamping groove and the annular groove engage, which facilitates the installation and removal of the power cord. At the same time, the stable shell 310 and the protective shell 320, together with the clamping groove, lock the power cord laterally to prevent the power cord from shifting, pulling, or loosening and causing poor contact. After disassembling the protective shell 320, the power cord can be directly removed, making the operation of maintenance and replacement of the line simple.

[0035] In this embodiment, a detector integrated body 610 is fixedly installed inside the stable housing 310. A positioning seat 620 is fixedly installed on the front side of the detector integrated body 610. A sliding hole is opened inside the positioning seat 620. A sliding rod 650 is inserted into the sliding hole. A pressing plate 660 is fixedly installed at the bottom of the sliding rod 650. A support spring is installed on the outside of the sliding rod 650. The support spring presses the sliding rod 650 and the pressing plate 660 downward, so that the pressing plate 660 and the power cord of the power distribution cabinet 100 are quickly pressed together, solving the problem of traditional bolts pressing the power cord.

[0036] In this embodiment, a first conductive plate 630 is fixedly installed on the outer side of the positioning seat 620, and a second conductive plate 640 is fixedly installed inside the first conductive plate 630. The second conductive plate 640 has evenly distributed bending grooves, and the second conductive plate 640 forms a wave shape with the bending grooves. The first conductive plate 630 and the second conductive plate 640 are electrically connected. The power cord of the distribution cabinet 100 extends between the second conductive plate 640 and the pressing plate 660. The wave-shaped second conductive plate 640 has elastic deformation capability. When the pressing plate 660 presses down on the power cord, the second conductive plate 640 fits tightly against the power cord, resulting in a larger conductive contact area and achieving a stable conductive effect. A control plate 670 is fixedly installed on the upper end of the sliding rod 650, and a pushing force is applied to the control plate 670. The sliding rod 650 and the clamping plate 660 are moved upwards, which quickly unlocks the clamping position of the power cord. The bottom of the control panel 670 has a sliding hole, and a positioning rod 680 is installed inside it. Both the positioning rod 680 and the sliding hole are hexagonal structures. A locking block 690 is fixedly installed on the rear side of the positioning rod 680. The corner of the positioning seat 620 has vertically distributed locking grooves. The locking block 690 is inserted into the locking groove. The upper end of the locking block 690 has an inclined surface. The locking block 690, together with the inclined surface, further presses and locks the clamping plate 660 downwards. A support spring is installed on the outside of the positioning rod 680. The support spring pushes and pulls the positioning rod 680, causing the locking block 690 to fit against the positioning seat 620. The power cord will not come loose even after long-term vibration of the device.

[0037] Example 2, based on Example 1, such as Figures 1-8 As shown, the detector integrated body 610, the fan 400, the detection sensor assembly 500, and the first conductive plate 630 are electrically connected respectively.

[0038] Example 3, based on Example 1, such as Figures 1-8 As shown, the stabilizing shell 310, the protective shell 320, and the drainage tube 330 work together to form a protective unit;

[0039] The detector integration body 610, positioning seat 620, first conductive plate 630, second conductive plate 640, sliding rod 650, pressing plate 660, control panel 670, positioning rod 680, and locking block 690 work together to form a detection unit.

[0040] The working principle of this embodiment:

[0041] When installing the monitoring device, first align the stabilizing housing 310 with the T-shaped plate and insert it into the stabilizing groove of the docking housing 110. Then, push the locking rod 200 through the locking hole with the spring to quickly lock the stabilizing housing 310 to the outside of the distribution cabinet 100.

[0042] Place the power cord from the distribution cabinet 100 into the clamping groove of the sturdy housing 310, then close the protective housing 320. The clamping groove engages with the annular groove on the outside of the power cord, thus locking the power cord and protecting the detection unit.

[0043] Pulling the control panel 670 upwards causes the sliding rod 650 and the clamping plate 660 to rise, placing the power cord above the second conductive plate 640. Then, releasing the control panel 670 causes the spring installed on the sliding rod 650 to press down the clamping plate 660, which quickly clamps the power cord. At the same time, the spring pushes the locking block 690 into the locking groove of the positioning seat 620, further locking the clamping plate 660. The power cord is tightly attached to the wavy second conductive plate 640, achieving stable conductivity.

[0044] When the fan 400 is started, the fan 400 generates suction to draw air from inside the distribution cabinet 100. All the airflow inside the distribution cabinet 100 flows through the detection sensor assembly 500. The detection sensor assembly 500 monitors the temperature and humidity inside the distribution cabinet 100 in real time. If the temperature and humidity exceed the standard, it promptly transmits the signal to the detector integration body 610.

[0045] When the power cord needs to be inspected and replaced, first disassemble the protective housing 320, pull the positioning rod 680 to disengage the locking block 690 from the locking groove, lift the control plate 670 to move the clamping plate 660 upward, and then take out the power cord for inspection and replacement.

[0046] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
