A power safety isolation and protection device

Abstract

This invention discloses a power safety isolation and protection device, comprising: a fencing assembly for forming an isolation component to protect power equipment; the fencing assembly includes: an isolation barrier placed directly on the ground to form an enclosure space; and a receiving groove provided on the side of the isolation barrier. When a person steps on the pedal, the prying transmission assembly transmits force to the compression assembly, causing the pressure block to move upwards. This causes the compression plate to compress the gas inside the chamber. The compressed gas enters the connecting pipe through a one-way valve, and finally, the airflow is ejected through the nozzle on the spray shell. The transparent moving component seals the receiving groove, ensuring that the flame-retardant liquid and warning sand particles are inside. The spray shell agitates the flame-retardant liquid, and the moving warning sand particles more easily attract the attention of people. Combining the sinking characteristic of stepping on the pedal with the moving sand particles, the warning is more dynamic and the warning effect is more ideal.

Description

Technical Field

[0001] This invention relates to the field of power equipment protection devices, specifically a power safety isolation and protection device. Background Technology

[0002] In our daily lives, electrical equipment is ubiquitous. Some of this equipment is mounted on the ground using bases, while others are installed at a certain distance above the ground using utility poles. After installation, protective devices are often installed around the equipment to isolate it. However, current protective devices simply involve setting up barriers and placing warning signs on them to alert people. This kind of warning effect is relatively static and limited, failing to address the forces exerted by people approaching. The barriers are fixed, and the fixed placement and limited warning function of the signs do not effectively attract people's attention, resulting in an unsatisfactory warning effect.

[0003] For example, a prefabricated substation isolation and protection device with bottom water-proof effect, disclosed in CN216476660U, includes: a support column, with guardrails installed on both adjacent sides of the support column, and a guardrail movably connected to one side of the guardrail; a docking block is provided at the bottom corner of the support column, and a limiting seat is provided on the outer side of the docking block; a docking groove is opened at the inner corner of the limiting seat, and the docking groove docks with the docking block; and the cross-sectional shape of the limiting seat is "L"-shaped; a sliding groove is opened at both ends of the limiting seat away from the docking groove; and a water-proof plate is provided below both support columns. This prefabricated substation isolation and protection device with bottom waterproofing achieves its waterproofing effect by installing waterproof plates that contact the ground between the support columns. The signs installed on the guardrail provide safety warnings, and the plugs welded to the bottom of the support columns enhance stability. However, the technical solution has the following problems: 1. The guardrail is fixed and lacks any dynamic warning components to enhance its effectiveness; it is simply a simple equipment enclosure. 2. The signs are fixed to the guardrail without any dynamic features, resulting in a single and relatively static warning function. 3. It does not utilize the force exerted by people approaching to activate the warning components. 4. This technical solution lacks a fire extinguishing structure, meaning it cannot extinguish fires in a timely manner when electrical equipment catches fire. Summary of the Invention

[0023] A through groove is formed on the positioning plate, and a central shaft is provided inside the through groove;

[0024] The pry bar is rotatably connected to the central shaft.

[0025] Optionally, the extrusion assembly includes:

[0026] An extrusion plate is disposed inside the extrusion chamber, and a pressure block is connected to the bottom of the extrusion plate;

[0027] An elastic element is connected to the bottom of the extrusion plate, and a fixing block is connected to the bottom of the elastic element. One side of the fixing block is fixedly connected to the inner wall of the extrusion chamber.

[0028] A sealing block is disposed in the opening at the top of the extrusion plate. A movable block is movably connected to the cavity inside the sealing block. A horizontal bar is connected to the bottom of the movable block via a vertical rod. The horizontal bar is fixedly connected to the inner wall of the opening at the top of the extrusion plate.

[0029] Optionally, the pressurized jet assembly includes:

[0030] A connecting pipe is provided on the isolation barrier to connect the receiving groove and the extrusion chamber;

[0031] A one-way valve is installed on the connecting pipe to form a one-way passage for the connecting pipe;

[0032] A jet shell is connected to the connecting pipe, and a jet port is provided on the jet shell.

[0033] Optionally, the transparent moving assembly includes a transparent baffle disposed inside the receiving groove, and a sealing gasket is connected to one side of the transparent baffle.

[0034] Optionally, the voltage regulator component includes:

[0035] A telescopic rod is connected to the inside of the gas chamber, and a stabilizing block is connected to the top of the telescopic rod. The stabilizing block can seal and separate the internal space of the gas chamber.

[0036] The second elastic element is sleeved on the surface of the telescopic rod;

[0037] A voltage stabilizing housing is connected to the stabilizing block, and the top of the voltage stabilizing housing extends through the isolation barrier, while an exhaust port is provided on the side of the voltage stabilizing housing.

[0038] Optionally, the container is filled with flame retardant liquid, and warning sand particles are placed inside the flame retardant liquid.

[0039] Optionally, both the first elastic element and the second elastic element are springs, which will return to their initial length after the compression or tension force disappears.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] The present invention features a step warning component on the enclosure assembly. When people approach the protective device due to inattention or other reasons, they will step down on the pedal. The pedal will move downward on the surface of the slide rail. This fully utilizes people's own life characteristics. When people step on the sinking object, they will unconsciously pull their feet back. This can warn people that they are already close to the power safety isolation and protection device, which is also very close to the power equipment. The warning mechanism is relatively dynamic.

[0042] The present invention provides a prying transmission component on the enclosure assembly. After people step on the pedal, the pry plate will be subjected to the force of the squeezing block, and the pry plate will rotate on the surface of the central shaft. This can transmit the force of people stepping on the pedal and make full use of the stepping force.

[0043] This invention, when people step on the pedal, prying up the transmission component transmits the force to the compression component, causing the pressure block to move upwards. This causes the compression plate to squeeze the gas in the chamber upwards. The squeezed gas enters the connecting pipe through a one-way valve, and finally, the airflow is ejected through the nozzle on the spray shell. The transparent moving component can seal the receiving tank, ensuring that the flame retardant liquid and warning sand particles are inside the receiving tank. The spray shell can agitate the flame retardant liquid, which effectively prevents the effective flame retardant components in the liquid from settling. On the other hand, it moves the warning sand particles, making them more likely to attract people's attention. Combining the sinking characteristic of stepping on the pedal with the moving sand particles, the warning is more dynamic, diverse, and has a more ideal warning effect, effectively preventing people from approaching the protective device.

[0044] This invention features a gas chamber and a pressure stabilizing component, which can store the gas flow generated by the force of stepping. After the gas is ejected from the jet shell, it moves upward in the flame-retardant liquid and finally enters the gas chamber through the passage above the receiving tank. The gas will squeeze the stabilizing block upward. Since the second elastic element can pull the stabilizing block, the stabilizing block will only move upward continuously when the gas continuously enters the gas chamber and gradually exceeds the elastic coefficient of the second elastic element. When the exhaust hole moves to the outside of the barrier, the gas chamber forms an airflow passage with the external space, which can discharge the gas. When the gas inside the gas chamber is continuously discharged, the pressure is not enough to keep the exhaust hole outside the barrier, and the second elastic element will drive the stabilizing block to move downward.

[0045] This invention utilizes the transparent and unobstructed nature of the transparent moving component to allow people to more clearly see the movement of the warning sand particles when they are stepped on. Furthermore, the transparent moving component is movably installed inside the receiving tank. When people accidentally bump into the transparent baffle, the baffle will squeeze the flame-retardant liquid, using the buffering properties of the liquid to provide good protection for people.

[0046] This invention features a controller that, when electrical equipment catches fire, allows users to open an electrically controlled valve. This releases the pressure within the gas chamber, causing the pressurized gas to compress the flame-retardant liquid in the containment tank. The liquid then flows through a nozzle into a spray shell and is finally ejected through holes in the shell, effectively extinguishing the fire. Furthermore, the flame-retardant liquid flows onto the ground, thus effectively preventing the spread of fire from sparks falling from burning electrical equipment above or from ignition points on ground-mounted equipment.

Detailed Implementation

[0060] 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.

[0061] Please see Figure 1-11 The present invention provides a power safety isolation and protection device, comprising:

[0062] Fence assembly 1, used to form an isolation component for the installation and protection of electrical equipment, includes:

[0063] The isolation barrier 101 is placed directly on the ground to form an enclosed space. A receiving groove 102 is provided on the side of the isolation barrier 101, forming a receiving space capable of holding objects. A gas chamber 103 is provided at the top inside the isolation barrier 101, and a compression chamber 104 is provided at the bottom inside the isolation barrier 101. The gas chamber 103 can hold gas. The receiving groove 102 is filled with flame-retardant liquid. Before use, the gas chamber 103 is pre-filled with gas, and the pressure generated by the pre-filled gas prevents the exhaust port on the pressure stabilizing shell 704 from venting. Warning sand particles are set inside the flame-retardant liquid. The warning color is relatively clear in the prior art, being red. Red is a well-known fact that it has a good warning effect. The sand particles are dyed with red pigment to form warning sand particles, making the warning sand particles more visible when moving in the flame-retardant liquid.

[0064] The slide 105 is located on the side of the guardrail 101. The slide 105 forms a movement path and provides movement space for the protrusions on the pedal 201.

[0065] The spray pipe 106 is connected to the guardrail 101, and an electrically controlled valve 107 is installed on the spray pipe 106. The electrically controlled valve 107 can be opened by the controller. One end of the spray pipe 106 is connected to a spray housing 108, which has holes. (See the instruction manual attached.) Figure 5 It is evident that the spray shell 108 is set at an angle. This design is intended to control the discharge angle of the flame retardant liquid, forming a parabola. The flame retardant liquid sprays over a wide area. The controller can open the electronically controlled valve 107, thus forming an open passage for fluid through the spray pipe 106, the spray shell 108, and the holes. The gas pressure in the gas chamber 103 will compress the flame retardant liquid in the receiving tank 102. The flame retardant liquid will enter the spray shell 108 through the spray pipe 106, and finally be sprayed out through the holes on the spray shell 108. This allows for fire extinguishing and flame retardant treatment of electrical equipment. The flame retardant liquid scattered on the ground within the space enclosed by the isolation fence 101 can also prevent the spread of fire from falling burning materials.

[0066] A limiting plate 109 is connected to the inner wall of the receiving groove 102, and the limiting plate 109 is fixedly connected to the inner wall of the receiving groove 102.

[0067] A trampling warning component 2 is installed on the fencing component 1. The trampling warning component 2 will sink when subjected to trampling force; this sinking characteristic can warn surrounding people. The trampling warning component 2 includes:

[0068] The pedal 201 is set on the surface of the guardrail 101. The inner wall of the pedal 201 is provided with a protrusion. The pedal 201 can move up and down on the surface of the guardrail 101. The pedal 201 is movably connected to the slide rail 202, which is slidably connected to the protrusion. The slide rail 202 is connected to the inside of the slide groove 105.

[0069] The squeezing block 203 is connected to the bottom of the pedal 201. When the protective device is installed, the pedal 201 is flush with the ground. When the pedal 201 is stepped on by people, it will move downwards, and the pedal 201 will drive the squeezing block 203 to move downwards.

[0070] The transmission assembly 3, which is mounted on the enclosure assembly 1, is used to transmit the downward pressing force of the step warning assembly 2. The transmission assembly 3 includes:

[0071] The positioning plate 301 is connected to the bottom of the isolation fence 101. The positioning plate 301 is fixedly connected to the bottom of the isolation fence 101. The positioning plate 301 is inserted into the ground to stabilize the position of the isolation fence 101.

[0072] The through groove 302 is formed on the positioning plate 301, and the through groove 302 is provided with a central shaft 303. The through groove 302 is set for the purpose of installing the central shaft 303, and also to provide space for the rotation of the pry plate 304.

[0073] The pry bar 304 is rotatably connected to the central shaft 303. The pry bar 304 is subjected to the downward pressure of the pressing block 203. The pry bar 304 rotates on the surface of the central shaft 303 and prys up the pressing block 408.

[0074] The extrusion assembly 4, mounted on the enclosure assembly 1, is used to propel airflow using the force transmitted from the prying transmission assembly 3. The extrusion assembly 4 includes:

[0075] The extrusion plate 401 is disposed inside the extrusion chamber 104, and the bottom of the extrusion plate 401 is connected to the pressure block 408.

[0076] Elastic element 402 is connected to the bottom of extrusion plate 401, and a fixing block 403 is connected to the bottom of elastic element 402. One side of fixing block 403 is fixedly connected to the inner wall of extrusion cavity 104.

[0077] A sealing block 404 is disposed within an opening at the top of the extrusion plate 401. A movable block 405 is movably connected to the cavity inside the sealing block 404. The bottom of the movable block 405 is connected to a horizontal rod 407 via a vertical rod 406. The horizontal rod 407 is fixedly connected to the inner wall of the opening at the top of the extrusion plate 401. When the pressure block 408 is subjected to an upward force, the pressure block 408 will drive the extrusion plate 401 to move upward. The upward movement of the extrusion plate 401 will stretch the elastic element 402. When the extrusion plate 401 moves upward, due to the sealing and extrusion characteristics, the sealing block 404 will block the opening at the top of the extrusion plate 401. In this way, the extrusion plate 401 and the sealing block 404 cooperate to extrude the gas in the cavity 104. Gas enters the connecting pipe 501 through the one-way valve 502. When the force of stepping on the pedal 201 disappears, the elastic element 402 will drive the extrusion plate 401 to move downward. Due to the setting of the one-way valve 502, no air will enter the extrusion chamber 104 from the top of the extrusion plate 401. As a result, the pressure in the space on the upper and lower sides of the extrusion plate 401 will be different. The gas pressure below the extrusion plate 401 will cause the sealing block 404 to move upward. The sealing block 404 will be released from the state of sealing the top opening of the extrusion plate 401. In this way, the extrusion plate 401 can move downward smoothly. The extrusion plate 401 will drive the pedal 201 to reset in sequence through the pressure block 408, the pry plate 304 and the extrusion block 203.

[0078] The pressurized jet assembly 5 is installed inside the enclosure assembly 1. The pressurized jet assembly 5 can use the airflow generated by the extrusion assembly 4 to blow the object. The pressurized jet assembly 5:

[0079] A connecting pipe 501 is installed on the isolation barrier 101 to connect the receiving groove 102 and the extrusion chamber 104.

[0080] A one-way valve 502 is installed on the connecting pipe 501 to form a one-way passage for the connecting pipe 501. The one-way valve 502 is configured to allow gas to enter the connecting pipe 501 from the extrusion chamber 104.

[0081] The spray shell 503 is connected to the connecting pipe 501, and the spray shell 503 has a spray nozzle. When gas enters the connecting pipe 501 through the one-way valve 502, the one-way valve 502 is open. The compressed gas generated by the upward movement of the extrusion plate 401 and the sealing block 404 will enter the spray shell 503 through the connecting pipe 501 and finally be sprayed out through the spray nozzle. The sprayed gas will blow the warning sand particles, and the warning sand particles will tumble in the flame retardant liquid, which will quickly attract the attention of the crowd. In addition, the gas can also agitate the flame retardant liquid to prevent the effective components in the flame retardant liquid from settling, ensuring that the flame retardant liquid can have an effective flame retardant effect. When the trampling force is gone, due to the setting of the one-way valve 502, the flame retardant liquid will not enter the extrusion chamber 104 through the spray shell 503, the spray nozzle and the connecting pipe 501.

[0082] A transparent movable component 6 is mounted on the enclosure component 1. The transparent movable component 6 exposes the warning mechanism, allowing surrounding people to clearly see it. A limiting plate 109 is used to block the transparent movable component 6. The transparent movable component 6 includes a transparent baffle 601 disposed inside the receiving groove 102. A sealing gasket 602 is connected to one side of the transparent baffle 601. The sealing gasket 602 is made of prior art rubber. The transparent baffle 601 is made of prior art transparent tempered glass. The transparent baffle 601 does not obstruct the view of the crowd, allowing them to clearly see the moving warning sand particles. Due to the setting of the limiting plate 109, the transparent baffle 601 will not detach from the receiving groove 102. Furthermore, as per the instruction manual... Figure 10 It is clearly visible that the outer edge of the sealing gasket 602 extends beyond the transparent baffle 601. When the sealing gasket 602 is placed in the receiving groove 102, it is compressed. Here, the compression sealing characteristics of rubber are utilized. When the external force collides with the transparent baffle 601, the transparent baffle 601 will move inside the receiving groove 102. The transparent baffle 601 will compress the flame retardant liquid and also play a buffering role.

[0083] The pressure stabilizing component 7, installed on the enclosure component 1, is used to store the collected gas and can also release gas when there is excess gas. The pressure stabilizing component 7 includes:

[0084] The telescopic rod 701 is connected inside the gas chamber 103, and a stabilizing block 702 is connected to the top of the telescopic rod 701. The stabilizing block 702 can seal and separate the internal space of the gas chamber 103.

[0085] Elastic element 2 703 is sleeved on the surface of telescopic rod 701. Both elastic element 1 402 and elastic element 2 703 are springs. The springs will return to their initial length after the compression or tension force is removed.

[0086] A pressure stabilizing shell 704 is connected to a stabilizing block 702. The pressure stabilizing shell 704 has an opening at the bottom and an exhaust port on the side. The top of the pressure stabilizing shell 704 penetrates the isolation barrier 101. The elastic element 703 causes a pressure difference between the outside of the pressure stabilizing shell 704, the area below the stabilizing block 702, and the inside of the pressure stabilizing shell 704. When gas enters the gas chamber 103, the elastic element 703 is stretched as gas continues to enter, causing the stabilizing block 702 and the pressure stabilizing shell 704 to move upwards. When the exhaust port moves to the isolation barrier 101... When the gas passes outside the enclosure 101, a gas passage is formed, and the exhaust port will release gas. As the gas is released, the gas pressure difference between the outside of the pressure stabilizing shell 704 and the bottom of the stabilizing block 702 and the inside of the pressure stabilizing shell 704 will change. The elastic element 703 will contract, and the stabilizing block 702 and the pressure stabilizing shell 704 will move downward. In this way, the exhaust port enters the enclosure 101 and no longer releases gas. When the electronically controlled valve 107 is opened, the elastic element 703 will drive the stabilizing block 702 and the pressure stabilizing shell 704 to move downward. The air pressure will squeeze the flame retardant liquid in the receiving tank 102, and the flame retardant liquid will enter the spray shell 108 through the spray pipe 106.

[0087] The controller is located on one side of the enclosure component 1. The controller is a PLC controller in the prior art. The most basic PLC controller can meet the requirements of this technical solution. The detailed model will not be described here. The staff can operate the controller. The controller can control the opening and closing of the electric valve 107. The controller is located on the right side of the isolation fence 101 and is installed on the ground.

[0088] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
