[0001] This invention relates to the field of fire protection pipeline monitoring technology, specifically to a section status monitoring device for underground power fire protection pipelines. Background Technology

[0002] Fire protection piping networks refer to piping systems specifically designed for fire protection, including indoor and outdoor fire water supply networks, fire hydrant water supply pipes, automatic sprinkler system pipes, foam extinguishing system water supply pipes, and indoor water mist extinguishing system pipes. The primary function of these piping systems is to transport fire-fighting water to support fire suppression and other fire protection needs. The presence or absence of leaks in the piping network is detected by monitoring devices; the state of leakage within the piping network is the status of a specific section of the fire protection piping network.

[0003] However, existing monitoring devices for the condition of underground fire protection pipe networks may only indicate whether there is a leak, but cannot reflect the extent of the leak. Furthermore, when the humidity in the air is high, the monitoring devices may falsely trigger alarms. Therefore, they do not meet the current requirements. To address this, we propose a condition monitoring device for underground fire protection pipe networks. Summary of the Invention

[0008] Preferably, the limiting mechanism includes a limiting plate that moves laterally inside the outer protective shell. Three movable columns are vertically arranged and fixedly connected to the outer end face of the limiting plate, and two connecting springs are vertically arranged and fixedly connected to the end face of the limiting plate. The three movable columns and the two connecting springs are arranged alternately, and three limiting grooves are vertically arranged on the inner end face of the limiting plate.

[0009] Preferably, the water-holding mechanism includes a water-holding box movable inside the outer protective shell. Two water level markers are vertically arranged and fixedly connected inside the water-holding box. Connecting frames are fixedly connected to both sides of the upper end of the water-holding box. An elastic copper sheet is fixedly connected to the inner end of each connecting frame. An active movable plate is fixedly connected to the upper end of each connecting frame. Connecting columns are fixedly connected to both sides of the water-holding box. A vertical movable block is fixedly connected to one end of each connecting column. Supporting springs are connected to both sides of the lower end of the water-holding box. A connecting pipe is connected to the middle of the lower end of the water-holding box, and a manual switch valve is connected to the lower end of the connecting pipe.

[0010] Preferably, the cross-section of the active movable plate is a triangular structure, and the inclined surface of the inner end of the active movable plate is pressed against the driven movable plate.

[0011] Preferably, one end of the elastic copper sheet is connected to the vertical movable block by a copper wire, and the other end of the elastic copper sheet is curled up at the bottom inside the water container.

[0012] Preferably, the connecting post is engaged in any one of the limiting grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention controls the height of the overall water collection mechanism by adjusting the amount of water leakage in the pipeline. This allows the connecting columns, vertical movable blocks, and contact blocks on both sides of the water collection mechanism to move at one end of three different copper plates. This results in different flashing colors of warning lights depending on the amount of leakage. When the upper warning light is powered on, it flashes green to remind maintenance personnel that the leakage is small. When the middle warning light is powered on, it flashes yellow to remind maintenance personnel that the leakage is larger than when it flashes green. However, when the lower warning light is powered on, it flashes red to remind maintenance personnel that the leakage is the largest. This design allows the detection device to reflect the size of different leakage situations, and maintenance personnel can select the appropriate tools for repair based on the size of the leakage. 2. This invention utilizes the solubility of electrolytes such as salt to enable electrical conduction between two elastic copper sheets. Under dry conditions, the two elastic copper sheets cannot conduct electricity. At the same time, under humid conditions, excessive dissolution of electrolytes such as salt will not occur, thus avoiding false alarms caused by excessive humidity. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1 to 6 An embodiment of the present invention provides a section status monitoring device for an underground power fire protection pipeline network, comprising a pipeline network 3, an annular sealing sleeve 4 being snapped into the connection of the pipeline network 3, an outer protective shell 1 being fixedly connected to the lower end of the annular sealing sleeve 4, water outlets 8 penetrating through both sides inside the annular sealing sleeve 4, a water flow control mechanism 5 being movably provided on both sides of the upper end inside the outer protective shell 1, a water flow holding mechanism 6 being provided at the lower end inside the outer protective shell 1, a connecting plate 9 being fixedly connected to both sides of the lower end of the outer protective shell 1, three copper plates 10 being vertically arranged on the end face of the connecting plate 9, and three warning lights 2 being vertically arranged at the front end of the outer side of the outer protective shell 1. The warning lights 2 are commonly used LED / 24V models on the market, and a lamp power connection module 12 is fixedly connected to both ends of the warning lights 2. One end of the lamp power connection module 12 is connected to the copper plate 10 on the connecting plate 9 through a copper wire. The flow control mechanism 5 includes an opening and closing plate 501. A driven movable plate 502 is fixedly connected to one side of the lower end of the opening and closing plate 501, and a rubber pad B504 is fixedly connected to the other side of the lower end of the opening and closing plate 501. The cross-section of the opening and closing plate 501 is set as a bent irregular structure. A rubber pad A503 is fixedly connected to the bent part of the inner end of the opening and closing plate 501. The bent irregular structure of the opening and closing plate 501 allows the two flow control mechanisms 5 to rotate and fit together, and also to swing and separate. The limiting mechanism 7 includes a limiting plate 701 that moves laterally inside the outer protective shell 1. Three movable columns 702 are vertically arranged and fixedly connected on the outer end face of the limiting plate 701. Two connecting springs 703 are vertically arranged and fixedly connected on the end face of the limiting plate 701. The three movable columns 702 and the two connecting springs 703 are arranged alternately. Three limiting grooves 704 are vertically arranged on the inner end face of the limiting plate 701. By providing through holes on the front and rear side walls of the outer protective shell 1, the movable column 702 moves through the through holes. The movable column 702 and the through holes improve the stability of the lateral movement of the overall limiting mechanism 7. When the overall water box 603 moves downward, the water box 603 drives the connecting column 605 to move vertically downward. The downward movement of the connecting column 605 presses the two limiting plates 701 downward. This pressing separates the two limiting plates 701, and the lateral movement of the limiting plates 701 causes the stretching force of the connecting spring 703 to be pressed. This enables the connecting column 605 to move from one of the limiting grooves 704 to the other limiting groove 704. The connecting column 605 is engaged in either of the limiting grooves 704. The water holding mechanism 6 includes a water holding box 603 that is movable inside the outer protective shell 1. Two water level marks 604 are vertically arranged and fixed inside the water holding box 603. Connecting brackets 602 are fixedly connected to both sides of the upper end of the water holding box 603. An elastic copper sheet 607 is fixedly connected to the inner end of the connecting bracket 602. The elastic copper sheet 607 can be rolled up and unrolled at the bottom of the water holding box 603. When the entire water holding box 603 moves downward, the elastic copper sheet 607 gradually extends from the rolled up state to the unrolled state. An active movable plate 601 is fixedly connected to the upper end of the connecting frame 602. Connecting columns 605 are fixedly connected to both sides of the water box 603. A vertical movable block 606 is fixedly connected to one end of the connecting column 605. Supporting springs 610 are connected to both sides of the lower end of the water box 603. A connecting pipe 608 is connected to the middle of the lower end of the water box 603. A manual switch valve 609 is connected to the lower end of the connecting pipe 608. Maintenance personnel can also open the manual switch valve 609 at the lower end of the connecting pipe 608 to release the water in the water box 603 through the connecting pipe 608.

[0020] The cross-section of the active movable plate 601 is designed as a triangular structure. The inclined surface of the inner end of the active movable plate 601 is pressed against the driven movable plate 502. One end of the elastic copper sheet 607 is connected to the vertical movable block 606 by a copper wire. The other end of the elastic copper sheet 607 is curled at the bottom inside the water box 603. Electrolytes, such as sodium chloride or other salt powders, can also be placed at the bottom inside the water box 603. When water leaks between the pipes 3, water can enter the interior of the water box 603 to dissolve the electrolyte. This aqueous solution greatly improves the conductivity of the elastic copper sheets 607 on both sides inside the water box 603.

[0021] A contact block 11 is fixedly connected to one end of a vertical movable block 606. The contact block 11 and one end of an elastic copper sheet 607 are fixedly connected to a copper wire between the vertical movable block 606 and the contact block 11 at one end of the vertical movable block 606, and any copper plate 10 is in contact with it. The two elastic copper sheets 607, the two contact blocks 11, the two copper plates 10, the two warning lights 2, the lamp power module 12, and the external power supply form a series circuit. When the inside of the water box 603 is dry, the two elastic copper sheets 607 are in a non-conductive open circuit state, so the warning light 2 is not powered on. When the pipe network 3 inside the annular sealing sleeve 4 leaks water, water will enter the inside of the water box 603 and wet the bottom of the inside of the water box 603. At this time, the two elastic copper sheets 607 can conduct electricity, thereby energizing the series circuit. The warning light 2 is powered on and alarms, thereby notifying maintenance personnel to repair the pipe network 3 inside the annular sealing sleeve 4. This design utilizes the solubility of electrolytes such as salt to conduct electricity between the two elastic copper sheets 607. In a dry environment, the two elastic copper sheets 607 cannot conduct electricity. At the same time, in humid conditions, it will not cause excessive dissolution of electrolytes such as salt, thus avoiding false alarms caused by high humidity.

[0022] Depend on Figure 7 It can be seen that the opening and closing plate 501 is movably connected to the lower end of the side wall inside the annular sealing sleeve 4 through a rotating shaft. The opening and closing plate 501 swings inside the outlet 8. The opening and closing plate 501 extends from the inside of the annular sealing sleeve 4 to the inside of the upper side of the outer protective shell 1. The lower end of the opening and closing plate 501 swings inside the outer protective shell 1.

[0023] When water leaks between the two pipe networks 3 inside the annular sealing sleeve 4, and the amount of leakage is small, the water inside the water box 603 fills to the water level mark 604 at the bottom layer. At this time, the overall weight of the water box 603 and the water inside it is relatively light. Therefore, the water box 603 remains unchanged under the support of the tension of the two supporting springs 610. The connecting posts 605 on both sides of the water box 603 remain engaged in the limiting groove 704 located at the upper end between the two limiting plates 701. At this time, the state structure of the water flow control mechanism 5 and the water flow holding mechanism 6 is as follows. Figure 5 As shown, this causes the contact block 11 at one end of the vertical movable block 606 to contact and be energized with the copper plate 10 located at the upper end of the connecting plate 9. This causes the two elastic copper sheets 607, the two contact blocks 11, the two copper plates 10 located on the upper layer, the two warning lights 2, the lamp power connection module 12, and the external power supply to form a closed series circuit. This causes the warning lights 2 located on the upper layer to be energized and to trigger an alarm. The warning lights 2 located on the upper layer flash green light to remind maintenance personnel that the amount of water leakage is small.

[0024] When the leakage between the two pipe networks 3 inside the annular sealing sleeve 4 further increases, the water inside the water-holding box 603 fills up to the bottom water level mark 604, submerging it. The water level then reaches the top water level mark 604. At this point, the overall weight of the water-holding box 603 and the water inside is significant, causing the water-holding box 603 to press against the two support springs 610. This causes the water-holding box 603 to move the connecting columns 605 on both sides downwards, resulting in the connecting columns 605 moving and engaging with the limiting plate 701. Within the limiting groove 704 in the middle, the contact block 11 at one end of the vertical movable block 606 contacts and is energized with the copper plate 10 located in the middle of the connecting plate 9. This causes the two elastic copper sheets 607, the two contact blocks 11, the two copper plates 10 in the middle layer, the two warning lights 2, the lamp power connection module 12, and the external power supply to form a closed series circuit. This causes the warning light 2 in the middle layer to be energized and alarm to sound. When the warning light 2 in the middle layer is energized, it flashes yellow light to remind maintenance personnel that the amount of water leakage is greater than when it flashes green light.

[0025] When the water flow between the two pipe networks 3 inside the annular sealing sleeve 4 increases again, the water in the water box 603 quickly fills up and submerges the water level mark 604 at the top. At this time, the overall weight of the water box 603 and the water inside further increases. The water box 603 continues to press down on the two supporting springs 610. The connecting column 605 moves down under the action of the water box 603 and is locked in the limiting groove 704 at the lower end of the limiting plate 701. The contact block 11 at one end of the vertical movable block 606 contacts and is energized with the copper plate 10 at the lower end of the connecting plate 9. This makes the two elastic copper sheets 607, the two contact blocks 11, the two copper plates 10 at the lower layer, the two warning lights 2, the lamp power module 12, and the external power supply form a closed series circuit. This makes the warning lights 2 at the lower layer energized and alarm. The warning lights 2 at the lower layer flash red light to remind the maintenance personnel that the amount of water leakage is the largest. In summary, by controlling the height of the overall water collection mechanism 6 based on the amount of water leakage in the pipe network 3, the connecting columns 605 on both sides, the vertical movable block 606, and the contact block 11 in the water collection mechanism 6 can move at one end of three different copper plates 10. This allows different amounts of leakage to cause different colors of the warning lights 2 to flash. When the upper warning light 2 is powered on, it flashes green to remind maintenance personnel that the amount of leakage is small. When the middle warning light 2 is powered on, it flashes yellow to remind maintenance personnel that the amount of leakage is larger than when it flashes green. However, when the lower warning light 2 is powered on, it flashes red to remind maintenance personnel that the amount of leakage is the largest. This setting allows the detection device to reflect the size of different leakage situations, and maintenance personnel can select tools for repair according to the size of different leakage situations.

[0026] As the water container 603 moves to its lowest position, it also drives the connecting frames 602 and the active movable plate 601 on both sides of the upper end to move downwards. During this downward movement, the inclined end of one side of the active movable plate 601 presses against the driven movable plate 502 on the lower side of the opening / closing plate 501, causing the lower ends of the two driven movable plates 502 to gradually come together. The rubber pads B504 and A503 between the two driven movable plates 502 also come together. This arrangement and operation improves the sealing performance between the two driven movable plates 502. Simultaneously, one end of the opening / closing plate 501 swings downwards within the outlet 8, and the lower end of the opening / closing plate 501 comes into contact with the lower end inside the outlet 8. At this point, the structural state of the water flow control mechanism 5 and the water flow holding mechanism 6 changes from... Figure 6 As shown, the water leaking from the pipe network 3 no longer flows downward between the two water flow control mechanisms 5, but gradually overflows upward from the outlets 8 on both sides. This setting and operation prevents water from continuously leaking into the water box 603 and overflowing, thereby preventing the water overflowing from the water box 603 from flooding the conductive components inside the outer protective shell 1.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
