Description

Technical Field

[0001] This utility model relates to the field of building spraying technology, specifically to a start / stop partition spraying water atomization device. Background Technology

[0002] In the field of building sprinkler technology, sprinkler water atomization devices are widely used in building fire protection, environmental humidification, cooling and dust removal and other scenarios. During installation, they are mainly installed on existing building partitions. The core requirement is to achieve stable water flow atomization and long-term reliable operation of the equipment.

[0003] Existing baffle spray water atomizing devices suffer from significant water flow impact and pressure fluctuations during operation. When the device starts, the pump drives a sudden surge of water into the pipeline, easily creating instantaneous high-pressure impacts. When it stops, the water flow velocity in the pipeline drops sharply, easily triggering water hammer. These two situations cause frequent impacts on the atomizing nozzles, delivery pipes, and connecting components, leading not only to unstable atomization (such as uneven atomized particle size) but also accelerating pipeline aging, interface leaks, shortening the overall lifespan of the equipment, and increasing maintenance costs.

[0004] Furthermore, existing baffle-type sprinkler atomizing devices lack flexibility in nozzle maintenance. Most nozzles are directly connected via pipe interfaces, lacking individual start / stop control mechanisms. When a single nozzle becomes clogged, damaged, or requires replacement or repair, the entire sprinkler system must be stopped to cut off the water flow to the corresponding pipe. This not only affects the continuity of sprinkler operations (e.g., interruption of protection in fire scenarios, pause of humidification / cooling in industrial workshops) but also reduces maintenance efficiency and increases indirect losses due to system downtime. Utility Model Content

[0005] The purpose of this invention is to provide a start / stop partition spray water atomization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a start / stop partition spray water atomizing device, comprising a water supply pipe, a pump body mounted on the water supply pipe, an input end connected to a clean water source, and an output end mounted on a buffer pipe, a buffer pressure stabilizing structure mounted on the buffer pipe, the buffer pressure stabilizing structure comprising an airbag-type buffer tank connected in parallel to the buffer pipe, a plurality of sets of conveying pipes sequentially mounted at the tail end of the buffer pipe, a spray atomizing unit mounted between two adjacent sets of conveying pipes, the conveying pipes and the spray atomizing unit both mounted on an existing partition structure, the spray atomizing unit comprising a three-way pipe, the two ends of the three-way pipe being connected to the conveying pipes on both sides respectively, and the other end of the three-way pipe being connected to a nozzle replacement start / stop structure, the output end of the nozzle replacement start / stop structure being equipped with an atomizing nozzle.

[0007] The present invention is further configured such that the buffer pressure stabilizing structure also includes a throttling pressure stabilizing valve, which is installed on the pipeline structure of the buffer pipe and located at the output end of the airbag type buffer tank.

[0008] The present invention is further configured such that the nozzle replacement start-stop structure includes a first connector and a second connector, a start-stop adjustment cavity is provided between the first connector and the second connector, a start-stop adjustment component is provided in the start-stop adjustment cavity, the first connector is threadedly sealed to the corresponding port of the tee pipe, and the second connector is threadedly sealed to the atomizing nozzle. Through the cooperation of the start-stop adjustment cavity, the first connector and the second connector, the nozzle replacement start-stop structure can be detachably installed at the tee pipe. In this way, after the nozzle replacement start-stop structure malfunctions, it can be disassembled separately without disassembling the tee pipe.

[0009] The present invention is further configured such that the start / stop adjustment assembly includes a fixed plate, which is fixedly installed inside the start / stop adjustment cavity. A first flow port is provided on the fixed plate. An adjustment plate is rotatably disposed inside the start / stop adjustment cavity. The bottom end of the adjustment plate is sealed to the top end of the fixed plate. A second flow port is provided on the adjustment plate. When the first and second flow ports are misaligned, the start / stop adjustment cavity is closed; when the first and second flow ports are aligned, the start / stop adjustment cavity is open. A rotation adjustment structure is provided inside the start / stop adjustment cavity in conjunction with the adjustment plate. The opening and closing of the start / stop adjustment cavity are achieved through the cooperation of the first flow port on the fixed plate and the second flow port on the adjustment plate. Therefore, when it is necessary to replace the atomizing nozzle, a single atomizing nozzle port can be closed, allowing for flexible replacement of individual atomizing nozzles without requiring a complete shutdown of the entire operation.

[0010] The present invention is further configured such that the rotation adjustment structure includes a gear, the side of the adjustment plate is provided with teeth, the gear meshes with the teeth, and the start / stop adjustment cavity is provided with a rotation drive structure in cooperation with the gear. Through the cooperation between the gear and the teeth, the rotation adjustment of the adjustment plate relative to the fixed plate can be realized, thereby realizing the rotation adjustment between the second flow port and the first flow port.

[0011] The present invention is further configured such that the rotation drive structure includes a drive shaft, the drive shaft extends to the outside of the start / stop adjustment cavity through a sealed bearing, and is provided with an adjustment knob. The rotation of the drive shaft is controlled by the adjustment knob to realize the rotation drive of the gear, and then the rotation drive of the adjustment plate is realized through the cooperation between the gear and the teeth.

[0012] The present invention is further configured such that a limiting protrusion is provided on the drive shaft, and a stabilizing seat is provided on the outer side of the start-stop adjustment cavity. An adjusting limiting groove is provided on the stabilizing seat in cooperation with the limiting protrusion. The limiting protrusion slides within the adjusting limiting groove. By adjusting the cooperation between the limiting groove and the limiting protrusion, the rotation range of the drive shaft can be limited. When the drive shaft drives the limiting protrusion to rotate from one end of the adjusting limiting groove to the other end, the first flow port and the second flow port can change from a mutually misaligned state to a mutually aligned state, or from a mutually aligned state to a mutually misaligned state, thereby realizing the precise opening and closing of the start-stop adjustment cavity.

[0013] The present invention is further configured such that the stabilizing base has a first locking groove, and the drive shaft has two second locking grooves that are configured to cooperate with the two ends of the adjusting limiting groove for rotational limiting positions. A positioning pin is inserted from the first locking groove into the second locking groove. The drive shaft drives the gear to rotate, and the rotation adjustment of the adjusting plate is achieved through the meshing between the gear and the teeth. After the first locking groove and the corresponding second locking groove are aligned, the positioning pin is inserted from the outside of the first locking groove into the second locking groove, which can lock and fix the drive shaft in the stabilizing base, improving the relative stability between the fixing plate and the adjusting plate. Here, the positioning pin can be installed on the stabilizing base by locking rope or chain to avoid loss.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Effectively mitigates water flow impact and ensures stable equipment operation: This device employs a dual buffer and pressure-stabilizing structure consisting of an air-bladder-type buffer tank and a throttling-type pressure-regulating valve, which can accurately handle water flow pressure fluctuations during pump start-up and shutdown. During startup, the air-bladder-type buffer tank first absorbs the instantaneous impact pressure, controlling the fluctuation within ±0.05MPa; the throttling-type pressure-regulating valve then gradually adjusts the water flow rate through a 1-3 second progressive opening of the valve core, achieving secondary flow control and preventing sudden increases in flow rate. During shutdown, the pressure-regulating valve first closes the inlet, then slowly releases pressure over ≥2 seconds, completely eliminating the water hammer effect and significantly reducing the impact of water flow on components such as the atomizing nozzle and delivery pipe, thus extending the equipment's service life.

[0015] 2. Individual nozzle start / stop capability, enhancing operational flexibility: The spray atomization unit of this device is equipped with a nozzle replacement start / stop mechanism. An adjustment knob controls the rotation of the drive shaft and gears. The gears and teeth mesh to rotate the adjustment plate relative to the fixed plate. By utilizing the alignment and misalignment of the first and second flow ports, the opening and closing of individual start / stop adjustment chambers is precisely controlled. When replacing a single atomizing nozzle, the overall spraying operation does not need to be stopped; only the corresponding nozzle's adjustment chamber needs to be closed. This greatly reduces the impact of maintenance on production or operations, improving the flexibility and efficiency of equipment use.

[0016] 3. The structural design is scientifically sound and balances sealing and stability: In the nozzle replacement start-stop mechanism, the fixed plate and adjusting plate utilize a composite structure of rigid sheet metal bonded with rubber sealing gaskets to ensure a tight seal and prevent water leakage. The limiting protrusion of the drive shaft and the adjusting limiting groove of the stabilizing seat precisely limit the rotation range, ensuring accurate switching of the flow outlet. Positioning pins inserted into the first and second locking grooves lock the drive shaft, enhancing the relative stability of the fixed plate and adjusting plate. Simultaneously, the threaded sealing connection of the first and second connectors facilitates individual disassembly and maintenance of the start-stop mechanism. The overall design balances practicality and reliability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: Please refer to Figures 1-7 A start / stop partition spray water atomizing device includes a water supply pipe 1, a pump body 2 installed on the water supply pipe 1, an input end of the water supply pipe 1 connected to a clean water source, and an output end of the water supply pipe 1 equipped with a buffer pipe 3. The buffer pipe 3 is equipped with a buffer pressure stabilizing structure, which includes an airbag-type buffer tank 4 connected in parallel to the buffer pipe 3. Multiple sets of conveying pipes 5 are sequentially installed at the tail end of the buffer pipe 3. A spray atomizing unit 6 is installed between two adjacent sets of conveying pipes 5. The conveying pipes 5 and the spray atomizing unit 6 are both installed on an existing partition structure. Their installation and fixing methods can be existing methods such as cable tie fixing or bracket fixing. The spray atomizing unit 6 includes a three-way pipe 7, with both ends of the three-way pipe 7 connected to the conveying pipes 5 on both sides respectively. The other end of the three-way pipe 7 is connected to a nozzle replacement start / stop structure. An atomizing nozzle 8 is installed at the output end of the nozzle replacement start / stop structure.

[0021] Please see Figures 1-7 As one implementation of the buffer pressure stabilizing structure: the buffer pressure stabilizing structure also includes a throttling pressure stabilizing valve 9, which is installed on the pipeline structure of the buffer pipe 3 and located at the output end of the airbag buffer tank 4.

[0022] Please see Figures 1-7 As one implementation of the nozzle replacement start-stop structure: The nozzle replacement start-stop structure includes a first connector 10 and a second connector 11. A start-stop adjustment cavity 12 is provided between the first connector 10 and the second connector 11. A start-stop adjustment component is provided in the start-stop adjustment cavity 12. The first connector 10 is threadedly sealed to the corresponding port of the three-way pipe 7. The second connector 11 is threadedly sealed to the atomizing nozzle 8. Here, the threaded sealing connection can be achieved by the cooperation of the threaded screwing structure and the sealing gasket. The start-stop adjustment chamber 12, the first connector 10, and the second connector 11 can be used to detachably install the nozzle replacement start-stop structure at the three-way pipe 7. In this way, if the nozzle replacement start-stop structure malfunctions, it can be disassembled separately without disassembling the three-way pipe 7.

[0023] Please see Figures 1-7As one implementation of the start-stop adjustment component: the start-stop adjustment component includes a fixed plate 13, which is fixedly installed in the start-stop adjustment cavity 12. The fixed plate 13 has a first flow port 14. An adjustment plate 15 is rotatably arranged in the start-stop adjustment cavity 12. The bottom end of the adjustment plate 15 is sealed and fitted with the top end of the fixed plate 13. The adjustment plate 15 has a second flow port 16. When the first flow port 14 and the second flow port 16 are misaligned, the start-stop adjustment cavity 12 is closed. When the first flow port 14 and the second flow port 16 are aligned, the start-stop adjustment cavity 12 is opened. The start-stop adjustment cavity 12 is equipped with a rotation adjustment structure in conjunction with the adjustment plate 15. The start-stop adjustment cavity 12 is opened and closed by the cooperation of the first flow port 14 on the fixed plate 13 and the second flow port 16 on the adjustment plate 15. Thus, when it is necessary to replace the atomizing nozzle 8, a single atomizing nozzle port can be closed, and the individual atomizing nozzle 8 can be flexibly replaced without stopping the entire operation.

[0024] Please see Figures 1-7 As one embodiment of the rotation adjustment structure: the rotation adjustment structure includes a gear 17, and the side of the adjustment plate 15 is provided with teeth 18. The gear 17 meshes with the teeth 18. The start-stop adjustment cavity 12 is equipped with a rotation drive structure that works with the gear 17. Through the cooperation between the gear 17 and the teeth 18, the rotation adjustment of the adjustment plate 15 relative to the fixed plate 13 can be realized, thereby realizing the rotation adjustment between the second flow port 16 and the first flow port 14.

[0025] Please see Figures 1-7 As one embodiment of the rotation drive structure: The rotation drive structure includes a drive shaft 19, which extends to the outside of the start / stop adjustment cavity 12 through a sealed bearing and is provided with an adjustment knob 20. The rotation of the drive shaft 19 is controlled by the adjustment knob 20 to realize the rotation drive of the gear 17, and then the rotation drive of the adjustment plate 15 is realized through the cooperation between the gear 17 and the teeth 18.

[0026] Please see Figures 1-7 As one implementation of the drive shaft 19: a limiting protrusion 21 is provided on the drive shaft 19, and a stabilizing seat 22 is provided on the outside of the start / stop adjustment cavity 12. An adjustment limiting groove 23 is provided on the stabilizing seat 22 in cooperation with the limiting protrusion 21. The limiting protrusion 21 slides within the adjustment limiting groove 23. By cooperating with the limiting groove 23 and the limiting protrusion 21, the rotation range of the drive shaft 19 can be limited. When the drive shaft 19 drives the limiting protrusion 21 to rotate from one end of the adjustment limiting groove 23 to the other end, the first flow port 14 and the second flow port 16 can change from a mutually misaligned state to a mutually aligned state, or from a mutually aligned state to a mutually misaligned state, thereby realizing the precise opening and closing of the start / stop adjustment cavity 12.

[0027] Please see Figures 1-7 As one embodiment of the stabilizing base 22: the stabilizing base 22 is provided with a first locking groove 24, and the drive shaft 19 is provided with two second locking grooves 25 to cooperate with the two ends of the adjusting limit groove 23 to rotate and limit the position. A positioning pin 26 is inserted from the first locking groove 24 into the second locking groove 25. The drive shaft 19 is controlled to drive the gear 17 to rotate. After the rotation adjustment of the adjusting plate 15 is achieved through the meshing between the gear 17 and the teeth 18, the positions of the first locking groove 24 and the corresponding second locking groove 25 are matched. The positioning pin 26 is inserted from the outside of the first locking groove 24 into the second locking groove 25, which can realize the locking and fixing of the drive shaft 19 in the stabilizing base 22, and improve the relative stability between the fixing plate 13 and the adjusting plate 15. Here, the positioning pin 26 can be installed on the stabilizing base 22 by locking rope or chain to avoid loss.

[0028] In summary, the working principle and specific workflow of this utility model are as follows: When this utility model is in use, the clean water source is sequentially delivered to the water supply pipe 1 and the buffer pipe 3 under the drive of the pump body 2; At the moment the water flows in, the airbag buffer tank 4 acts as the first-stage buffer, which can directly absorb the instantaneous impact pressure (such as the sudden increase in pressure when the water flows from stillness to flow) delivered from the existing clean water supply module (filtered municipal water and other water sources) when the pump body 2 starts. When the pump body 2 starts, the instantaneous impact pressure is absorbed by the compression of the airbag in the airbag buffer tank 4, and the pressure fluctuation range is controlled within ±0.05MPa. As a second-stage buffer, the throttling pressure regulating valve 9 needs to perform a second "refined flow control" on the water flow after the initial pressure stabilization. This is achieved by gradually opening the valve core of the throttling pressure regulating valve 9 (1-3 seconds) to avoid the problem of "sudden increase in flow rate" that may still exist in the water flow after the initial pressure stabilization. This ensures that the water flow pressure and flow rate entering the spray atomization unit 6 are smoothly transitioned, which can greatly reduce the impact of the water flow on components such as the atomizing nozzle 8 and the delivery pipe 5. When the pump body 2 stops, the throttling pressure regulating valve 9 first closes the inlet end, and then slowly releases the pressure in the pipeline through its built-in pressure relief structure (pressure relief time ≥ 2 seconds). Here, the "inlet end" of the throttling pressure regulating valve 9 refers to the inlet end of the pressure regulating valve itself, that is, the port connected to the outlet end of the airbag buffer tank 4. What is released is the residual pressure in the pipeline between the buffer tank and components such as the spray atomizing unit 6 and the delivery pipe 5, which completely eliminates the water hammer effect. Here, the throttling pressure regulating valve 9 has a pressure relief structure inside, which is the existing structure of the throttling pressure regulating valve 9. This utility model will not describe this part in detail. In this utility model, the spray atomizing unit 6 includes a three-way pipe 7, a nozzle replacement start-stop structure, and an atomizing nozzle 8 that cooperate with each other. By setting the nozzle replacement start-stop structure, when replacing or repairing a single atomizing nozzle 8, it is not necessary to stop the overall atomizing spray operation. The opening and closing control of the three-way pipe 7 can be realized by the opening and closing control of the nozzle replacement start-stop structure, which facilitates the flexible replacement of individual atomizing nozzles 8. When the nozzle is running with the start-stop mechanism changed, the drive shaft 19 can be rotated by adjusting the knob 20, which in turn controls the gear 17 to rotate. The rotation control of the adjusting plate 15 is achieved through the meshing structure between the gear 17 and the teeth 18, so that the second flow port 16 on the adjusting plate 15 rotates relative to the first flow port 14. When the first flow port 14 and the second flow port 16 are engaged, the start-stop adjusting chamber 12 is in the open state, and the atomizing nozzle 8 sprays water mist. When the first flow port 14 and the second flow port 16 are misaligned, the start-stop adjustment chamber 12 is in a closed state, so the water flow cannot be sprayed out through the nozzle replacement start-stop structure, thus allowing for flexible individual replacement of the atomizing nozzle 8. In this utility model, both the fixed plate 13 and the adjusting plate 15 can be composite plate structures made of rigid plates pressed together or bonded with rubber sealing gaskets, so that the two sets of rubber sealing gaskets between the adjusting plate and the fixed plate are in contact with each other, thereby achieving a sealed combination between the contact surfaces of the fixed plate 13 and the adjusting plate 15, and achieving a seal when the first flow port 14 and the second flow port 16 are misaligned. In this utility model, the top of the adjusting plate 15 is preferably stably installed in the start-stop adjusting cavity 12 through the cooperation of a hollow shaft and a bearing.
