Description

Technical Field

[0001] This utility model relates to the technical field of salt spray test chambers, specifically a polyurethane waterproof composite material salt spray test chamber. Background Technology

[0002] Salt spray test chambers are mainly used to simulate salt spray environments to test the corrosion resistance of materials or products. In order to detect the service life of polyurethane waterproof composite materials in corrosive environments, salt spray test chambers can efficiently test polyurethane waterproof composite materials in simulated corrosive environments.

[0003] Currently, salt spray test chambers have certain drawbacks in actual use. The cover of a traditional salt spray test chamber is colorless and transparent, but during use, the transparency of the cover is easily reduced by the salt spray. As the salt spray rises and adheres to the inner wall of the cover, the user's ability to observe the inside of the test chamber through the cover will be reduced.

[0004] In view of this, a polyurethane waterproof composite salt spray test chamber was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A polyurethane waterproof composite salt spray test chamber includes a test chamber and a cover assembly movably mounted on the test chamber. The cover assembly includes a transparent cover, on the inner wall of which are symmetrically distributed back track strips and front track strips. The back track strips have transverse grooves inside. A wiper is movably mounted on the outside of the back track strips and front track strips. A pad is fixedly mounted inside the wiper and is adapted to pass through the transverse groove. A bidirectional lead screw is movably mounted in the transverse groove of the wiper, and a motor is mounted on the outer end of the bidirectional lead screw. The bidirectional lead screw is threaded into the pad. A horizontally placed conduit is installed inside the wiper and is connected to a groove on the inner side of the wiper.

[0007] In a preferred embodiment, the present invention can be further configured such that: two studs are fixedly installed on the outer end of the transparent cover, a housing is installed on the outside of the two studs, and the motor is fixedly installed inside the housing.

[0008] In a preferred embodiment, the present invention can be further configured such that: a protective tube is fixedly installed inside the transparent box cover, the tube segment of the conduit extending to the outside of the scraper is adapted to be inserted into the protective tube, and an insertion hole is provided on the back of the transparent box cover.

[0009] In a preferred embodiment, the present invention can be further configured such that: a fog-absorbing hood is installed on the outside of the back track and the front track, and an exhaust pipe is fixedly installed on the fog-absorbing hood, and the exhaust pipe is adapted to communicate with the inner cavity of the fog-absorbing hood.

[0010] In a preferred embodiment, the present invention can be further configured such that: an air inlet is provided on the inner side of the mist suction hood, and the air inlet faces the wiper hood.

[0011] In a preferred embodiment, the present invention can be further configured such that: one section of the wiper away from the mist suction hood is adapted to fit against the inner wall of the transparent box cover, and a gap is reserved between the other section of the wiper and the inner wall of the transparent box cover.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model involves fixing symmetrically distributed front and back track strips to the inner wall of an existing transparent box cover, and movably installing symmetrically distributed mist suction hoods and wiper hoods on the two track strips. When the motor starts and drives the bidirectional lead screw to rotate, the wiper hood will move along the outside of the two track strips toward the mist suction hood. The regularly extending wiper hood can clean the inner wall of the transparent box cover, ensuring that the transparent box cover is always kept clean and convenient for users to observe in a timely manner.

[0013] 2. This utility model uses an exhaust hood to exhaust air outwards. After the transparent cover and the experimental chamber are closed, the salt mist generated inside the closed chamber will be continuously exhausted outwards by the mist suction hood, ensuring that the user can clearly observe the inside of the experimental chamber through the cleaned transparent cover.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the polyurethane waterproof composite material salt spray test chamber provided by this utility model.

[0019] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a polyurethane waterproof composite material salt spray test chamber, including a test chamber 100 and a cover assembly 200 movably installed on the test chamber 100. When the cover assembly 200 is lowered or raised, the salt spray obstructs the user's view.

[0020] The cover assembly 200 includes a transparent cover 210. Symmetrically distributed back track strips 230 and front track strips 240 are fixedly installed on the inner wall of the transparent cover 210. A transverse groove is formed inside the back track strip 230. A wiper 260 is movably installed on the outside of the back track strip 230 and the front track strip 240. A pad 2601 is fixedly installed inside the wiper 260, and the pad 2601 is adapted to penetrate into the transverse groove. The wiper 260 is movably installed within the transverse groove. The device is equipped with a bidirectional lead screw 280, and a motor 2201 is installed at the outer end of the bidirectional lead screw 280. The bidirectional lead screw 280 is threaded into a pad 2601. A horizontally placed conduit 270 is installed inside the wiper 260, and the conduit 270 is connected to a groove on the inner side of the wiper 260. Two studs 2101 are fixedly installed at the outer end of the transparent cover 210. A housing 220 is installed on the outside of the two studs 2101, and the motor 2201 is fixedly installed inside the housing 220. A protective tube 2102 is fixedly installed inside the transparent box cover 210. The tube section of the conduit 270 that extends to the outside of the scraper cover 260 is adapted to be inserted into the protective tube 2102, and an insertion hole 2103 is provided on the back of the transparent box cover 210.

[0021] Preferably, both the back track 230 and the front track 240 are made of fiberglass, and the inner wall of the transverse groove is provided with holes. The section of the bidirectional screw 280 that passes through the transverse groove is adapted to be inserted into the hole, and the section of the bidirectional screw 280 that passes through the transverse groove is adapted to pass through the outside of the transparent cover 210. The external hose is connected to the conduit 270. As the motor 2201 runs, its internal drive shaft, in conjunction with the bidirectional lead screw 280, propels the wiper 260 to move laterally along the back track 230 and the front track 240. After moving laterally, the wiper 260 removes the salt spray liquid accumulated on the inner wall of the transparent cover 210. The transparent cover 210 remains clean after the liquid is removed, allowing the user to effectively observe the inner cavity of the experimental chamber 100 through the clean transparent cover 210.

[0022] Example 2: Combination Figures 3 to 5 As shown, in the above embodiment, a fog suction hood 250 is installed on the outside of the back track 230 and the front track 240. An exhaust pipe 2501 is fixedly installed on the fog suction hood 250, and the exhaust pipe 2501 is adapted to communicate with the inner cavity of the fog suction hood 250. An air inlet is opened on the inner side of the fog suction hood 250, and the air inlet faces the wiper hood 260. One section of the wiper 260, away from the mist suction hood 250, is fitted to the inner wall of the transparent cover 210, and a gap is reserved between another section of the wiper 260 and the inner wall of the transparent cover 210.

[0023] Preferably, the width and shape of the mist suction hood 250 and the wiper hood 260 are the same, and both ends of the mist suction hood 250 and the wiper hood 260 are provided with inwardly recessed semi-cylindrical slots. The wiper hood 260 is fixedly connected to the plate segment that fits against the inner wall of the transparent box cover 210 with a thickened cotton sheet. As the wiper 260 slides laterally against the inner wall of the transparent cover 210, the salt spray liquid accumulated on the inner wall of the transparent cover 210 will be effectively gathered. The gathered salt spray liquid will eventually be transferred into the groove of the wiper 260, and the salt spray liquid that has entered the groove inside the wiper 260 will be discharged outward through the conduit 270.

[0024] The working principle and usage process of this utility model are as follows: When in use, the transparent box cover 210 is flipped to the side along the top of the experimental machine box 100 until the bottom end of the transparent box cover 210 is completely closed in the port at the top of the experimental machine box 100. At this time, the mist suction hood 250 is located at one end of the inner side of the transparent box cover 210, while the liquid scraper hood 260 at the other end of the inner cavity of the transparent box cover 210 is in a ready-to-slide state. When the experimental chamber 100 and cover assembly 200 are in use, and a large amount of water mist appears on the inside of the transparent cover 210, obstructing the user's view of the interior of the experimental chamber 100 through the transparent cover 210, the motor 2201 is operated until the internal drive shaft of the motor 2201 rotates in conjunction with the bidirectional lead screw 280. Since the pad 2601 is adapted to pass through the transverse groove inside the rear track 230, the rotating bidirectional lead screw 280 will help the pad 2601 and the wiper 260 slide laterally along the inner wall of the transparent cover 210. During the lateral sliding, the wiper 260 can quickly remove the water droplets accumulated on the inner wall of the transparent cover 210, ensuring that the transparent cover 210 can always be kept clean and not obstruct the user's view.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
