Description
Technical Field
[0001] This utility model relates to the field of rainwater simulation technology, and more specifically, to a simulated rainwater environment experimental chamber. Background Technology
[0002] In existing technologies, rain simulation test chambers are widely used in fields such as building material testing and waterproof performance evaluation of outdoor equipment. However, these devices still have many shortcomings in structural design and operation, especially in the adjustment of spray angle and the installation and maintenance of spray rings. Currently, most rain simulation test chambers on the market use fixed nozzles or spray rings, and their spray angle and direction are difficult to adjust flexibly after being set during installation. Because the spray angle is not adjustable, the simulated rain impact angle remains unchanged, making it difficult to realistically reproduce rainfall scenarios under different wind and rain conditions, thus affecting the accuracy and adaptability of the experiment.
[0003] Most spray rings in existing equipment are fixed with screws, flanges, or welded. While this ensures sealing and connection strength, it also brings some significant problems. When the spray ring needs to be cleaned, replaced, or maintained, it often requires disassembling multiple connecting parts and using specialized tools, which increases the difficulty of operation. Frequent disassembly can easily damage the sealing structure or connecting parts, causing potential water leakage and increasing maintenance costs. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a simulated rainwater environment test chamber to solve the technical problems mentioned in the background art, such as the inconvenience of adjusting the spray angle, the inconvenience of installing and disassembling the spray ring, and the inconvenience of maintenance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a simulated rainwater environment test chamber, comprising a chamber body, a spray rotation mechanism, a mounting and snapping mechanism, and a snapping auxiliary mechanism. The spray rotation mechanism includes a side frame, a support shaft, a spray ring, a rotating frame, and a waterproof rotating motor. The side frame is located inside the chamber body, the support shaft is symmetrically mounted on the top end of the side frame, the waterproof rotating motor is mounted on the top end of the side frame, and the rotating frame is symmetrically mounted on both ends of the spray ring. The rotating frame is connected to the support shaft, and the other end of the rotating frame is connected to the output end of the waterproof rotating motor. The mounting and snapping mechanism includes a snap-fit tube, a snap-fit rod, a locking frame, a locking spring, and a snap-fit groove. The snap-fit rod can extend into the interior of the snap-fit tube, the snap-fit groove is located on the side wall of the snap-fit rod, the locking frame is laterally slidably mounted on the outer wall of the snap-fit tube, and the locking spring is installed between the locking frame and the outer wall of the snap-fit tube. The locking spring pulls the locking frame into the snap-fit groove, fixing the snap-fit rod inside the snap-fit tube.
[0006] The present invention is further configured such that the snap-fit auxiliary mechanism includes a rotating sleeve, a spiral plate, a directional ring, a spiral groove, and a slope ring. The rotating sleeve is rotatably mounted on the outer wall of the snap-fit tube, the spiral plate is mounted on the top end of the rotating sleeve, the directional ring is slidably mounted on the outer wall of the snap-fit tube, the spiral groove is set on the outer wall of the directional ring, and the spiral plate and the spiral groove are slidably connected. The rotation of the spiral plate drives the directional ring to move longitudinally back and forth, and the slope ring at the top end of the directional ring pushes the locking frame away from the snap-fit groove, thereby releasing the snap-fit rod from the snap-fit tube.
[0007] The present invention is further configured such that support plates are symmetrically installed on the inner wall of the box, and the side frame is installed on the support plates through the mounting and snapping mechanism. The symmetrical installation of the support plates enhances the structural stability and provides fixing points for the side frame.
[0008] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixedly installed on the bottom end face of the support plate. The connecting plate fixes the position of the clamping tube and enhances the stability of the clamping system.
[0009] The present invention is further configured such that a bottom box is installed at the bottom end of the inner wall of the box body, and the spray ring is arranged opposite to the bottom box. The bottom box collects experimental water for easy recycling or discharge.
[0010] The present invention is further configured such that a side plate is provided at the bottom end of the side frame, and a snap-fit rod is installed on the side plate. The snap-fit rod can extend through the support plate and engage with the snap-fit tube. The side plate enhances the strength of the bottom of the side frame and provides an installation point for the snap-fit rod.
[0011] The present invention is further configured such that a water supply pipe is installed at the top end of the spray ring, and the water supply pipe is a flexible hose, with one end of the water supply pipe extending out of the housing to connect with an external water supply device. The flexible hose design of the water supply pipe increases flexibility and facilitates connection with an external water supply system.
[0012] The present invention is further configured such that an unlocking block is installed at the bottom end of the locking frame, and the slope ring can push the unlocking block to move the locking frame outward. The unlocking block simplifies the unlocking operation and improves the work efficiency of the operator.
[0013] Compared with the prior art, this utility model provides a simulated rainwater environment test chamber, which has the following beneficial effects:
[0014] This invention features a spray rotation mechanism. The spray ring is driven by a rotating frame and a waterproof rotary motor to achieve a uniform spraying effect. The cooperation between the rotary motor and the spray ring ensures uniform coverage of the simulated rain environment, improving the accuracy of the experiment. The waterproof rotary motor design prevents the motor from being damaged by water, ensuring the stability and durability of the equipment during long-term use.
[0015] This utility model is equipped with an installation snap-fit mechanism. The connection between the snap-fit rod and the snap-fit tube adopts a telescopic design. Combined with the structure of the locking frame and the locking spring, it simplifies the installation and disassembly process of the equipment. The locking spring automatically pulls the locking frame to fix the snap-fit rod, which is convenient for quick installation and disassembly. The design of the locking frame ensures that the snap-fit rod is firmly fixed in the snap-fit tube, thereby improving the stability and reliability of the system.
[0016] This invention incorporates a locking auxiliary mechanism. The cooperation between the spiral plate and the spiral groove allows the directional ring to reciprocate longitudinally within the locking tube, precisely controlling the unlocking process of the locking rod. The slope ring, by pushing the unlocking block, simplifies the release operation of the locking rod, reduces manual intervention, and improves unlocking efficiency and ease of operation. The design of the directional ring ensures accurate matching between the locking rod and the locking tube, preventing loosening or insecure locking due to improper operation.

[0026] Please see Figures 1-5 A simulated rainwater environment test chamber includes a chamber body 1, a spray rotation mechanism, a mounting and snapping mechanism, and a snapping auxiliary mechanism. The spray rotation mechanism includes a side frame 2, a support shaft 3, a spray ring 4, a rotating frame 5, and a waterproof rotary motor 6. The side frame 2 is located inside the chamber body 1. The support shaft 3 is symmetrically mounted on the top end of the side frame 2. The waterproof rotary motor 6 is mounted on the top end of the side frame 2. The rotating frame 5 is symmetrically mounted on the spray ring 4. One end of the rotating frame 5 is connected to the support shaft 3, and the other end of the rotating frame... 5 is connected to the output end of the waterproof rotary motor 6. The mounting snap-fit mechanism includes a snap-fit tube 7, a snap-fit rod 8, a locking frame 9, a locking spring 10, and a snap-fit groove 11. The snap-fit rod 8 can extend into the interior of the snap-fit tube 7. The snap-fit groove 11 is set on the side wall of the snap-fit rod 8. The locking frame 9 is laterally slidably mounted on the outer wall of the snap-fit tube 7. The locking spring 10 is installed between the locking frame 9 and the outer wall of the snap-fit tube 7. The locking spring 10 pulls the locking frame 9 into the snap-fit groove 11, fixing the snap-fit rod 8 inside the snap-fit tube 7.
[0027] In this embodiment, when the system is started, the waterproof rotary motor 6 drives the spray ring 4 to rotate, while the external water supply equipment supplies water to the spray ring 4 through the water supply pipe 20 in the form of a hose. The spray ring 4 sprays water while rotating, so as to achieve a uniform simulated rainfall effect. Because the motor adopts a waterproof design, it ensures reliable operation in humid environments. The rotation of the spray ring 4 can change the direction and distribution of water flow, simulating rainfall conditions of different intensities and distributions. During assembly, the snap-fit rod 8 is installed on the side plate 19 at the bottom of the side frame 2, and the snap-fit tube 7 is fixed to the support plate 16 through the connecting plate 17. During installation, the snap-fit rod 8 is inserted into the snap-fit tube 7 through the support plate 16. At this time, the snap-fit groove 11 on the side wall of the snap-fit rod 8 corresponds to the locking bracket 9 on the outer wall of the snap-fit tube 7. Under the tension of the locking spring 10, the locking bracket 9 automatically extends into the snap-fit groove 11, locking the snap-fit rod 8 in the snap-fit tube 7, thus achieving a firm connection between the side frame 2 and the support plate 16. This design allows the spray system to be stably installed in the housing 1, withstanding the force generated by the rotational movement without loosening.
[0028] The snap-fit auxiliary mechanism includes a rotating sleeve 101, a spiral plate 12, a directional ring 13, a spiral groove 14, and a slope ring 15. The rotating sleeve 101 is rotatably mounted on the outer wall of the snap-fit tube 7. The spiral plate 12 is mounted on the top end of the rotating sleeve 101. The directional ring 13 is slidably mounted on the outer wall of the snap-fit tube 7. The spiral groove 14 is located on the outer wall of the directional ring 13. The spiral plate 12 and the spiral groove 14 are slidably connected. The rotation of the spiral plate 12 drives the directional ring 13 to move longitudinally back and forth. The slope ring 15 at the top end of the directional ring 13 pushes the locking frame 9 away from the snap-fit groove 11, thereby disengaging the snap-fit rod 8 from the snap-fit tube 7.
[0029] In this embodiment, when it is necessary to unlock, the rotating sleeve 101 installed on the outer wall of the locking tube 7 is manually rotated, which drives the spiral plate 12 at its top to rotate. The spiral plate 12 slides in cooperation with the spiral groove 14 on the outer wall of the directional ring 13, converting the rotational motion into the longitudinal movement of the directional ring 13. As the directional ring 13 moves upward, the slope ring 15 at its top pushes the unlocking block 21 on the locking frame 9, so that the locking frame 9 overcomes the tension of the locking spring 10 and moves away from the slot 11, thereby unlocking the locking rod 8 from the locking tube 7. The locking rod 8 can then be pulled out of the locking tube 7 to disassemble the side frame 2.
[0030] Please see Figures 1-5 As a supplementary implementation of a simulated rainwater environment test chamber for the spray rotation mechanism, the mounting and snapping mechanism, and the snapping auxiliary mechanism: Support plates 16 are symmetrically installed on the inner wall of the chamber 1. Side frames 2 are mounted on the support plates 16 via mounting and snapping mechanisms. A connecting plate 17 is installed at the bottom end of the side wall of the snapping pipe 7, and the connecting plate 17 is fixedly installed on the bottom end face of the support plate 16. A bottom box 18 is installed at the bottom end of the inner wall of the chamber 1, and the spray ring 4 is positioned opposite to the bottom box 18. A side plate 19 is provided at the bottom end of the side frame 2, and a snapping rod 8 is installed on the side plate 19. The snapping rod 8 can extend through the support plate 16 and engage with the snapping pipe 7. A water supply pipe 20 is installed at the top end of the spray ring 4. The water supply pipe 20 is a flexible hose, and one end of the water supply pipe 20 extends out of the chamber 1 to connect with an external water supply device. An unlocking block 21 is installed at the bottom end of the locking frame 9, and the slope ring 15 can push the unlocking block 21 to move the locking frame 9 outward.
[0031] More specifically, the spray rotation mechanism is mounted on the support plate 16 on the inner wall of the housing 1 via a mounting snap-fit mechanism. The snap-fit rod 8 passes through the support plate 16 and extends into the snap-fit tube 7. The locking frame 9 automatically extends into the snap-fit groove 11 under the action of the locking spring 10 and locks. One end of the water supply pipe 20 on the spray ring 4 is connected to the external water supply equipment to ensure water supply. The waterproof rotary motor 6 is started to drive the spray ring 4 to start rotating. At the same time, the water supply is turned on, and the water flow is evenly sprayed through the spray ring 4 to form a simulated rainwater environment inside the housing 1. The bottom box 18 is used to collect the sprayed water flow. When it is necessary to disassemble or adjust the spray system, the rotating sleeve 101 in the snap-fit auxiliary mechanism is rotated. Through the cooperation of the spiral plate 12 and the spiral groove 14, the directional ring 13 is moved. The slope ring 15 pushes the unlocking block 21 on the locking frame 9 to release the lock between the snap-fit rod 8 and the snap-fit tube 7, which facilitates the disassembly of the side frame 2 and the maintenance and management of the spray system.
[0032] In summary, during use or operation of the overall equipment: when the spray rotation mechanism is in operation, it simulates the spraying and distribution of rainwater. After the system starts, the waterproof rotary motor 6 drives the spray ring 4 to rotate, while the external water supply equipment supplies water to the spray ring 4 through a flexible water supply pipe 20. As the spray ring 4 rotates, it sprays water, achieving a uniform simulated rainfall effect. Because the motor is waterproof, it ensures reliable operation in humid environments. The rotation of the spray ring 4 can change the direction and distribution of the water flow, simulating rainfall of different intensities and distributions.
[0033] When the snap-fit mechanism is installed, it is used to fix the connection between the side frame 2 and the support plate 16 on the inner wall of the box 1. During the assembly process, the snap-fit rod 8 is installed on the side plate 19 at the bottom of the side frame 2, and the snap-fit tube 7 is fixed to the support plate 16 through the connecting plate 17. During installation, the snap-fit rod 8 is inserted into the snap-fit tube 7 through the support plate 16. At this time, the snap-fit groove 11 on the side wall of the snap-fit rod 8 corresponds to the locking bracket 9 on the outer wall of the snap-fit tube 7. Under the tension of the locking spring 10, the locking bracket 9 automatically extends into the snap-fit groove 11 and locks the snap-fit rod 8 in the snap-fit tube 7, thus realizing a firm connection between the side frame 2 and the support plate 16. This design allows the sprinkler system to be installed firmly in the box 1 and withstand the force generated by the rotation without loosening.
[0034] When the locking auxiliary mechanism is needed, it is used to assist in releasing the locking state of the locking mechanism, so as to facilitate the disassembly or adjustment of the spray system. When it is necessary to release the lock, the rotating sleeve 101 installed on the outer wall of the locking tube 7 is manually rotated, which drives the spiral plate 12 at its top to rotate. The spiral plate 12 slides in cooperation with the spiral groove 14 on the outer wall of the directional ring 13, converting the rotational motion into the longitudinal movement of the directional ring 13. As the directional ring 13 moves upward, the slope ring 15 at its top pushes the unlocking block 21 on the locking frame 9, so that the locking frame 9 overcomes the tension of the locking spring 10 and moves away from the slot 11, thereby releasing the locking rod 8 from the locking tube 7. The locking rod 8 can be pulled out of the locking tube 7 to realize the disassembly of the side frame 2.
[0035] The spray rotation mechanism is mounted on the support plate 16 on the inner wall of the housing 1 via a snap-fit mechanism. The snap-fit rod 8 passes through the support plate 16 and extends into the snap-fit tube 7. The locking frame 9 automatically extends into the snap-fit groove 11 under the action of the locking spring 10 and locks. One end of the water supply pipe 20 on the spray ring 4 is connected to the external water supply equipment to ensure water supply. The waterproof rotary motor 6 is started to drive the spray ring 4 to start rotating. At the same time, the water supply is turned on, and the water flow is evenly sprayed through the spray ring 4 to form a simulated rainwater environment inside the housing 1. The bottom box 18 is used to collect the sprayed water flow. When it is necessary to disassemble or adjust the spray system, the rotating sleeve 101 in the snap-fit auxiliary mechanism is rotated. Through the cooperation of the spiral plate 12 and the spiral groove 14, the directional ring 13 is moved. The slope ring 15 pushes the unlocking block 21 on the locking frame 9 to release the lock between the snap-fit rod 8 and the snap-fit tube 7, which facilitates the disassembly of the side frame 2 and the maintenance and management of the spray system.

For all the fixed connections mentioned above, welding is preferred.
