Description

Technical Field

[0001] This invention relates to the field of flood control and emergency response technology for underground power distribution rooms, and in particular to a flood control and emergency response device for underground spaces. Background Technology

[0002] In the existing power industry, traditional flood control and emergency facilities, such as sandbags and drainage pumps, have relatively simple functions; in terms of intelligent flood control and emergency response, although there have been some preliminary explorations and applications, the overall technology is still immature.

[0003] Traditional emergency equipment is mostly wheeled or fixed, which is difficult to adapt to complex terrain with pits and debris, and cannot quickly and accurately reach the work site. Furthermore, environmental monitoring and equipment control rely on manual operation, making it difficult to grasp changes in on-site parameters in real time. This can easily lead to secondary faults such as short circuits in power distribution equipment due to human error. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flood control emergency device for underground spaces, which can realize automated cleaning and anti-clogging functions, has strong applicability to various scenarios, high stability, and a simple structure that is easy to repair and maintain.

[0005] To address the aforementioned technical problems, this invention provides a flood control emergency device for underground spaces, comprising: a modular container body, a tracked chassis mounted on the bottom of the modular container body, and a pumping unit mounted on the tracked chassis; the pumping unit includes: a pumping unit body, an inlet filter barrel fitted onto one end of the pumping unit body, an outlet end mounted on the opposite end of the pumping unit body, and multiple piston cylinders installed inside the pumping unit body, one end of each piston cylinder being connected to the inlet filter barrel; the pumping unit is equipped with an inlet... One end of the filter barrel is equipped with a scraper and multiple nozzles. Multiple piston cylinders are each equipped with multiple first liquid outlet pipes that correspond one-to-one with the multiple nozzles. Multiple piston cylinders are each equipped with multiple second liquid outlet pipes. The filter barrel slides back and forth along the pumping unit body, which in turn causes the multiple piston cylinders to move back and forth. The piston cylinders spray water toward the scraper through the first liquid outlet pipes and nozzles to clean the impurities on the scraper. The piston cylinders also spray water toward the inner wall of the filter barrel through the multiple second liquid outlet pipes to clean the inner wall of the filter barrel.

[0006] The inlet filter barrel has multiple sets of filter holes, and the outer wall of the inlet filter barrel is in close contact with the inner wall of the pumping unit body. External water enters the interior of the pumping unit body through the multiple sets of filter holes on the inlet filter barrel. Impurities attached to the outer wall of the inlet filter barrel are scraped off by a scraper bar, which is in the shape of a ring.

[0007] The piston cylinder further includes: a piston cylinder body, a liquid inlet on the piston cylinder body, and an air bladder connected to the piston cylinder body. A first liquid outlet pipe is connected to the piston cylinder body. The piston cylinder body extends and retracts, pressing the liquid drawn into the piston cylinder body through the liquid inlet into the first liquid outlet pipe.

[0008] The inlet and the first outlet pipe are each equipped with a one-way solenoid valve; an electrically controlled one-way valve is installed between the piston cylinder body and the air bladder.

[0009] The pumping unit body is equipped with a motor, a screw, a threaded sleeve, and a connecting rod. One end of the motor is connected to the screw, the threaded sleeve is fitted onto the screw, one end of the connecting rod is connected to the threaded sleeve, and the other end of the connecting rod is connected to the inlet filter barrel. The screw rotates under the drive of the motor, and the screw moves back and forth linearly on the threaded sleeve. The connecting rod drives the inlet filter barrel to slide back and forth on one end of the pumping unit body.

[0010] One end of the second liquid outlet pipe is connected to the airbag, and the other end of the second liquid outlet pipe is connected to the water spray ring installed inside the water pumping unit body. The water spray ring is equipped with multiple sets of water spray nozzles.

[0011] The pumping unit body is equipped with a support frame for fixing the spray ring.

[0012] The pumping unit body has a water outlet at the liquid outlet end, and a pump is connected to the water outlet.

[0013] The pumping unit itself is a hollow cylinder.

[0014] The modular cabin is equipped with a drying unit for quickly drying the underground space floor and walls, and a ventilation unit for improving the air quality of the underground space.

[0015] The flood control emergency device for underground spaces according to the present invention has the following beneficial effects: First, the inlet filter barrel slides back and forth along the pumping unit body, causing multiple piston cylinders to reciprocate. The piston cylinders spray water towards the scraper through the first outlet pipe and nozzle to clean the impurities on the scraper. The piston cylinders also spray water towards the inner wall of the inlet filter barrel through multiple second outlet pipes to clean the inner wall of the inlet filter barrel. Impurities can be continuously removed without manual intervention, avoiding equipment blockage and ensuring operational stability.

[0026] 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.

[0027] like Figures 1-7 The image shows a first embodiment of the flood control emergency device for underground spaces according to the present invention.

[0028] The flood control emergency device for underground spaces in this embodiment of the invention includes: a modular container body 1, a tracked chassis 2 installed at the bottom of the modular container body 1, and a pumping unit 3 installed on the tracked chassis 2. The modular container body 1 is also equipped with a drying unit 4 for quickly drying the underground space floor and walls. The modular container body 1 is also equipped with a ventilation unit 5 for improving the air quality of the underground space. The ventilation module 5 can further solve problems such as the accumulation of harmful gases and oxygen deficiency that easily arise after water accumulation.

[0029] In this embodiment, by integrating a water pumping unit 3, a drying unit 4, a ventilation unit 5, and other functional units, such as a water pumping unit, a monitoring unit, and an emergency lighting unit, into the main body 1 of the container, the problems of numerous types of equipment and accessories that need to be carried during emergency repairs, easy omissions, and high manpower consumption are solved. This improves the efficiency of space and scene utilization, resolves the conflict between the limited volume of the container and the convenient transportation of the container, and optimizes the modular design, which will increase the efficiency of scene utilization by 30%.

[0030] Furthermore, by coordinating with pumping unit 3, drying unit 4, ventilation unit 5, and other functional units such as pumping unit, monitoring unit, and emergency lighting unit, intelligent disaster monitoring technology and functional module collaborative control technology are realized. During pumping, ventilation, or drying operations, a control ball is also carried for convenient remote control operation and to transmit on-site conditions (monitoring and alarming of water level, floating objects, etc.) back to the back-end command and dispatch system. In underground spaces without network access, a MESH self-organizing network terminal can be installed to build a local area network, achieving an accuracy rate of over 90% in monitoring and alarming water level, floating objects, and other environmental conditions; and a 100% timeliness rate for video transmission.

[0031] The integration of functional units also facilitates rapid deployment and transfer, thereby saving manpower, reducing personnel safety risks, and improving the speed and convenience of the mobile cabin reaching disaster areas and being transferred to multiple points.

[0032] In this embodiment, by installing a tracked chassis 2 on the main body 1 of the container, it can adapt to complex underground terrain and narrow passages. The drive motor provides power and can smoothly pass through areas with water accumulation, potholes, and debris accumulation. The emergency container 1 can be accurately deployed around the work site, and if necessary, it can be stably supported by hydraulic outriggers.

[0033] Furthermore, the pumping unit 3 is capable of drawing in external water, and includes: a pumping unit body 31, an inlet filter barrel 32 sleeved on one end of the pumping unit body 31, an outlet end 33 installed on the opposite end of the pumping unit body 31, and a plurality of push piston cylinders 34 installed inside the pumping unit body 31. One end of the plurality of push piston cylinders 34 is respectively connected to the inlet filter barrel 32, and the pumping unit body 31 is in the shape of a hollow cylinder.

[0034] The pumping unit 3 is equipped with a scraper 41 and multiple nozzles 42 on one end of the inlet filter barrel 32. Multiple piston cylinders 34 are each equipped with multiple first outlet pipes 341 that are connected to the multiple nozzles 42 in a one-to-one correspondence. Multiple piston cylinders 34 are each equipped with multiple second outlet pipes 342. The inlet filter barrel 32 slides back and forth along the pumping unit body 31, which causes the multiple piston cylinders 34 to move back and forth. The piston cylinders 34 spray water toward the scraper 41 through the first outlet pipes 343 and the nozzles 42 to clean the impurities on the scraper 41. The piston cylinders 34 spray water toward the inner wall of the inlet filter barrel 32 through the multiple second outlet pipes 344 to clean the inner wall of the inlet filter barrel 32.

[0035] In this embodiment, multiple sets of filter holes 322 are provided through the liquid inlet filter bucket 32, and the outer wall of the liquid inlet filter bucket 32 ​​is in close contact with the inner wall of the pumping unit body 31. The external water enters the interior of the pumping unit body 31 through the multiple sets of filter holes 322 on the liquid inlet filter bucket 32. The impurities attached to the outer wall of the liquid inlet filter bucket 32 ​​are scraped off by the scraper 41, which is in the shape of a ring.

[0036] Multiple piston cylinders 34 are fixedly connected to the inner wall of the pumping unit body 31. The piston cylinder 34 also includes: a piston cylinder body 341, a liquid inlet 342 opened on the piston cylinder body 341, and an air bag 345 connected to the piston cylinder body 341, and a first liquid outlet pipe 343 connected to the piston cylinder body 341.

[0037] The extension and retraction end of the piston cylinder 34 is fixedly connected to the inlet filter barrel 32. The piston cylinder 34 is equipped with a first outlet pipe 343 and a second outlet pipe 344 with one-way valves. The piston cylinder 34 slides within the pumping unit body 31 through the inlet filter barrel 32. The extension and retraction of the piston cylinder body 341 forces the liquid drawn into the piston cylinder body 341 from the inlet 342 into the first outlet pipe 343.

[0038] One end of the second liquid outlet pipe 344 is connected to the air bag 345, and the other end of the second liquid outlet pipe 344 is connected to the water spray ring 36 installed inside the water pumping unit body 31. The water spray ring 36 is provided with multiple sets of water spray nozzles, which face the inner wall of the liquid inlet filter barrel 32. The water spray ring 36 is connected to the second liquid outlet pipe 344.

[0039] Furthermore, multiple nozzles 42 are installed at an angle and facing the scraper 41 to clean impurities on the scraper 41. The multiple nozzles 42 are connected one-to-one with the multiple first liquid outlet pipes 343 of the multiple piston cylinders 34.

[0040] Preferably, a one-way solenoid valve is provided on the liquid inlet 342 and the first liquid outlet 343 respectively; an electrically controlled one-way valve T is installed between the piston cylinder body 341 and the air bag 345.

[0041] Furthermore, the pumping unit body 31 is equipped with a motor 351, a screw 352, a threaded sleeve 353, and a connecting rod 354. One end of the motor 351 is connected to the screw 352, the threaded sleeve 353 is fitted onto the screw 352, one end of the connecting rod 354 is connected to the threaded sleeve 353, and the other end of the connecting rod 354 is connected to the inlet filter barrel 32. The screw 352 rotates under the drive of the motor 351, and the screw 352 moves back and forth linearly on the threaded sleeve 353 in conjunction with it. The connecting rod 354 drives the inlet filter barrel 32 to slide back and forth on one end of the pumping unit body 31.

[0042] Preferably, the pumping unit body 31 is internally equipped with a support frame 37 for fixing the spray ring 36. In this embodiment, the motor 351 can also be fixed by the support frame 37.

[0043] Preferably, the liquid outlet 33 of the pumping unit body 31 is provided with a water outlet hole 331, and a pumping pump is connected to the water outlet hole 331.

[0044] In this embodiment, when the pumping unit 3 is used, the motor 351 is started, and the output end of the motor 351 drives the screw 352 to rotate. Since the threaded sleeve 353 is threadedly connected to the screw 352, and the threaded sleeve 353 is fixed to the inlet filter barrel 32 through the connecting rod 354, the inlet filter barrel 32 is driven to slide back and forth in the pumping unit body 31.

[0045] External water enters the pumping unit body 31 through the filter holes 322 on the inlet filter bucket 32. Debris such as leaves and plastic fragments in the water are intercepted on the outer wall of the inlet filter bucket 32. When the inlet filter bucket 32 ​​slides into the pumping unit body 31, the outer wall of the inlet filter bucket 32 ​​contacts the scraper 41. The scraper 41 scrapes off the impurities adhering to the outer wall of the inlet filter bucket 32 ​​to prevent clogging of the filter holes 322.

[0046] As the inlet filter tank 32 slides back and forth, it drives the telescopic ends of multiple piston cylinders 34 to reciprocate. When the telescopic ends of the piston cylinders 34 extend, water is drawn into the pumping unit body 31 through the inlet 342 (with a built-in one-way valve, water only flows into the piston cylinder body 341 from the inlet 342). When the telescopic ends of the piston cylinders 34 retract, the water in the piston cylinder body 341 is discharged through the first outlet pipe 343 (with a built-in one-way valve, water only flows out from the piston cylinder body 341) and flows to multiple sets of inclined nozzles 42. The nozzles 42 spray liquid toward the scraper 41 to wash away impurities on the scraper 41 and prevent impurities from accumulating and affecting the scraping effect.

[0047] Some of the water discharged from the piston cylinder body 341 flows into the air bladder 345 for storage through the one-way solenoid valve T. When the amount of water stored in the air bladder 345 reaches the threshold or is triggered by a timer, the solenoid valve of the second outlet pipe 344 opens, and the water in the air bladder 345 flows to the water spray ring 8 through the second outlet pipe 344. Multiple sets of water spray nozzles on the outer ring surface of the water spray ring 8 spray water toward the inner wall of the inlet filter barrel 32, backflushing and cleaning the inner wall of the inlet filter barrel 32 to prevent the inner side of the filter holes 322 from being blocked, and ensuring the continuous and efficient operation of the device.

[0048] The water entering the pumping unit body 31 is eventually discharged from the outlet 331 to the designated area by the pump, completing the water extraction operation.

[0049] It is understandable that through the reciprocating motion of the inlet filter bucket 32 ​​of the pumping unit 3, the scraper 41 removes impurities, the nozzle 42 washes, and the water in the airbag 345 flows through the second outlet pipe 344 to the spray ring 8 to achieve an automated cleaning mechanism. Impurities can be continuously removed without manual intervention, avoiding equipment blockage and ensuring operational stability. In other embodiments of the flood control emergency device for underground spaces in this invention, data can be collected in real time by the monitoring unit and operations can be automatically triggered, reducing the frequency of manual entry into dangerous areas and avoiding safety risks. At the same time, the entire operation process can be remotely monitored in the background to achieve intelligent management and control. The collaborative operation of multiple units forms a closed-loop emergency process of "water extraction, air purification, moisture drying and full-process monitoring", which can quickly restore the safe environment of underground spaces, avoid short circuits of power distribution equipment due to water accumulation, moisture or corrosion by harmful gases, and effectively reduce property losses and safety risks in flood control emergencies.

[0050] The flood control emergency device for underground spaces according to the present invention has the following beneficial effects: First, the inlet filter barrel slides back and forth along the pumping unit body, causing multiple piston cylinders to reciprocate. The piston cylinders spray water towards the scraper through the first outlet pipe and nozzle to clean the impurities on the scraper. The piston cylinders also spray water towards the inner wall of the inlet filter barrel through multiple second outlet pipes to clean the inner wall of the inlet filter barrel. Impurities can be continuously removed without manual intervention, avoiding equipment blockage and ensuring operational stability.

[0051] Secondly, the tracked chassis is adapted to complex underground terrain and narrow passages, and each functional module can move and operate as needed to meet the emergency needs of multiple scenarios.

[0052] Third, it has a simple structure, high stability, and is easy to repair and maintain.
