Description

Technical Field

[0001] This invention relates to the field of dehumidification technology, specifically to an automatic induction dehumidification system for a chassis dynamometer pit. Background Technology

[0002] The pit space in the heavy commercial vehicle dynamometer laboratory is large, and rainwater easily seeps into it during heavy rains. Currently, there is no effective automatic drainage system, and the pit must be manually checked periodically for water accumulation. If checks are not timely, water can seep into the dynamometer if it exceeds the equipment's safety limit, causing short circuits, component damage, and bearing rust. Each repair not only incurs huge expenses but also stops the equipment from operating, halting testing and resulting in both wasted time and significant economic losses. Previous records show that equipment failures due to water accumulation require approximately 10 days of downtime for repairs, impacting testing progress and significantly affecting the equipment's lifespan. Therefore, this application proposes an automatic induction-based dehumidification system for the chassis dynamometer pit. Summary of the Invention

Detailed Implementation

[0020] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: Example 1: like Figures 1 to 15 As shown, the present invention provides an automatic induction-based dehumidification system for chassis dynamometer pits, comprising: Water pump 1 is installed at the bottom of pit 10; The frame 2 is installed on the wall of the pit 10, and a slide rail 20 is installed on it; The lifting mechanism 3 is mounted on the slide rail 20 and moves up and down along the multi-faceted inner wall of the pit 10. The wiping component 4 is mounted on the lifting mechanism 3 and moves with the lifting mechanism 3 to wipe water along the multi-sided inner wall of the pit 10. The sensing component 5 is mounted on the frame 2 and electrically connected to the water pump 1 to monitor the water level in the pit 10.

[0021] Specifically, the sensing component 5 is a water level sensor; it also includes a central control unit, with the water pump 1 electrically connected to the central control unit. The central control unit uses a high-performance microprocessor, which can respond quickly within 2 seconds after receiving a signal and send a start command to the water pump 1. The water pump 1 is a high-power, corrosion-resistant submersible pump to meet the requirements of rapid drainage. After the submersible pump 1 starts, it pumps out the water accumulated in the pit 10 and then discharges it to a safe outdoor drainage area through a drainage pipe.

[0022] See Figure 3 and Figure 4The lifting mechanism 3 is at least one set, preferably two sets; the lifting mechanism 3 includes a drive motor 31, a lead screw 32, a slider 33 and a moving beam 34. The drive motor 31 is set on the upper part of the frame 2, the lead screw 32 is rotatably set in the slide rail 20, and the slider 33 is slidably set in the slide rail 20 and threadedly connected to the lead screw 32; the moving beam 34 is detachably connected to the slider 33 so that multiple moving beams 34 are connected to the slider 33 to form a rectangular frame structure to scrape the water from the inner wall of the pit 10.

[0023] See Figure 4 The slider 33 has an L-shaped structure. The two ends of the moving beam 34 are provided with connecting grooves and connecting holes that communicate with the connecting grooves. The two ends of the slider 33 are inserted into the connecting grooves so that the connecting holes are horizontally aligned with the mounting holes on both sides of the slider 33.

[0024] Specifically, see Figure 1 and Figure 3 The wiper components 4 are multiple, and their ends can be fitted together to form a rectangular frame structure. Alternatively, the wiper components 4 can be disassembled to facilitate the removal of individual wiper components 4. Furthermore, the frame 2 of the present invention is equipped with at least two lead screws 32 to drive the moving beam 34, and a vertical limiting rod is also provided in one of its slide rails 20 to limit the sliders 33 located therein, so that the multiple sliders 33 can perform synchronous lifting and lowering movements.

[0025] Specifically, the invention also includes a dehumidifier, which is installed inside the frame 2 or the pit 10; the dehumidifier is electrically connected to the sensing component 5. When the water level sensor detects that the water level has dropped below the safety warning line, it sends a signal to the central control unit. Upon receiving the signal, the central control unit controls the water pump 1 to stop working and starts the dehumidifier installed in the pit 10. The dehumidifier uses professional industrial-grade equipment and can dehumidify up to 200 liters per day, effectively reducing the humidity inside the pit 10.

[0026] The working principle of this invention is as follows: When the sensing component 5, located at the lower part of the frame 2 inside the pit 10, senses that the water level in the pit 10 has reached a predetermined level, the central control unit controls the water pump 1 to operate, thereby pumping out the water in the pit 10. Simultaneously, the central control unit controls the lifting mechanism 3 to drive the scraper component 4 to descend and scrape the water against the wall of the pit 10, pushing the water towards the water pump 1 to facilitate drainage.

[0027] Example 2: As another embodiment of the present invention, such as Figure 3 and Figure 4As shown, the wiper component 4 is inclinedly positioned at the lower part of the moving beam 34. When the water pump 1 starts, the central control unit synchronously sends a signal to the drive motor 31. After the drive motor 31 starts, the drive screw 32 drives the slider 33 to move, thereby moving the wiper component 4 along the slide rail 20 towards the water pump 1. The wiper blade is made of water-resistant and wear-resistant material and fits tightly against the wall of the pit 10. During movement, it can scrape off the water accumulated on the wall of the pit 10, accelerating the accumulation of water towards the water pump 1, thereby improving the overall drainage efficiency.

[0028] Example 3: As another embodiment of the present invention, such as Figure 6 and Figure 7 As shown, the squeegee 4 is rotatably mounted on one side of the movable beam 34, directly opposite the wall of the pit 10.

[0029] See Figure 6 and Figure 7 as well as Figure 9 The frame 2 has a guide groove 21 on its side along the vertical direction, and the wiper component 4 has guide protrusions 7 at both ends. The guide protrusions 7 slide within the guide groove 21. The upper and lower parts of the guide groove 21 are provided with elastic switching elements 6, so as to change the direction of the wiper component 4 through the elastic switching elements 6.

[0030] Example 4: As another embodiment of the present invention, such as Figure 7 and Figure 8 As shown, the guide groove 21 includes guide groove one 211 and guide groove two 212. The elastic switching member 6 is rotatably disposed between guide groove one 211 and guide groove two 212 by means of an arc spring 8, so that when the wiper component 4 moves through the elastic switching member 6, it switches from one guide groove 21 to the other guide groove 21 when it moves in the opposite direction. This allows the descending wiper component 4 to adjust its distance from the wall of the pit 10 under the action of guide groove one 211 and guide groove two 212, so that the wiper component 4 can fit against the wall of the pit 10 when descending and disengage from the wall of the pit 10 when rising.

[0031] Further, see Figure 7 and Figure 8 An arc-shaped groove is provided between guide groove 211 and guide groove 21. The arc-shaped spring 8 is located in the arc-shaped groove. A limit block is provided at the lower end of the elastic switching member 6. The limit block is slidably located in the arc-shaped groove and abuts against the arc-shaped spring 8 so that the elastic switching member 6 can return to its original position under the action of the arc-shaped spring 8.

[0032] Example 5: As another embodiment of the present invention, such as Figure 7 and Figure 9As shown, the vertical cross-section of the wiper component 4 is a V-shaped structure; the V-shaped wiper component 4 is provided with an upper wiper part 41 and a lower wiper part 42, and the guide protrusion 7 is provided with a guide protrusion one 71 and a guide protrusion two 72. The guide protrusion one 71 is provided on the upper wiper part 41, and the guide protrusion two 72 is provided on the lower wiper part 42; when the upper wiper part 41 moves upward, it adheres to the wall of the pit 10 through the guide groove one 211 and descends to pass through the elastic switching member 6 at the bottom. When it moves upward, the guide protrusion one 71 cuts into the guide groove two 212 through the elastic switching member 6 at the bottom, so that the lower wiper part 42 adheres to the wall of the pit 10 and rises.

[0033] Further, see Figure 7 and Figure 8 A connecting groove 213 is provided between guide groove 1 211 and guide groove 212. The connecting groove 213 is located at the upper and lower parts of guide groove 21, respectively, and is located below the upper elastic switching member 6 and above the lower elastic switching member 6, so that guide protrusion 2 72 and guide protrusion 1 71 can move from one guide groove 21 to the other guide groove 21, so that when guide protrusion 1 71 descends linearly in guide groove 1 211, the upper scraper 41 moves in contact with the wall of pit 10, and the lower scraper moves away from the wall of pit 10 by guide protrusion 2 72 moving in guide groove 212; when guide protrusion 2 72 rises linearly in guide groove 1 211, the lower scraper 42 moves in contact with the wall of pit 10, and the upper scraper moves away from the wall of pit 10 by guide protrusion 1 71 moving in guide groove 212.

[0034] Specifically, see 7 and Figure 8 The two elastic switching members 6 located at the upper and lower parts of the guide groove 21 are tilted to one side and abut against the second guide groove 212. When the guide protrusion 7 moves in the second guide groove 212 and contacts the elastic switching member 6, it pushes the protrusion 7 to rotate towards the first guide groove 211 to compress the arc spring 8, so that the guide protrusion 7 passes through. After the guide protrusion 7 has completely passed through, the elastic switching member 6 returns to its original position under the action of the arc spring 8. At this time, the guide protrusion 7 moves in the opposite direction and slides into the inclined surface of the elastic switching member 6 to cut into the first guide groove 211, so as to realize the switching of the upper scraper 41 and the lower scraper 42 and contact with the wall of the pit 10.

[0035] Further, see Figure 7 and Figure 9 The upper scraper 41 and the lower scraper 42 are provided with bent portions. The bottom of the bent portion of the lower scraper 42 is provided with a through groove so that the rising scraper 4 can drip the water collected by the lower scraper 42 through the through groove to the bottom of the pit 10.

[0036] Example 6: As another embodiment of the present invention, such as Figures 10 to 14As shown, the squeegee component 4 includes a horizontal scraper 401 and a vertical scraper 402, and also includes a longitudinally arranged bidirectional screw 9. Both ends of the bidirectional screw 9 are threadedly connected to the horizontal scraper 401. One end of the bidirectional screw 9 is connected to a servo motor 91 via a reducer. The bidirectional screw 9 is horizontally arranged, and the servo motor 91 is vertically mounted on the moving beam 34. The servo motor 91 drives the bidirectional screw 9 to rotate, thereby causing the two opposing horizontal scrapers 401 to move relative to each other. This allows the horizontal scrapers 401 to descend and scrape the wall of the pit 10 to the bottom, while the longitudinally arranged bidirectional screw 9 drives the horizontal scrapers 401 to move relative to each other, pushing the accumulated water towards the water pump 1 at the bottom of the pit 10.

[0037] Specifically, see Figure 14 The transversely arranged movable beam 34 has L-shaped plates 92 fixed at both ends. The two ends of the bidirectional screw 9 are rotatably connected to the L-shaped plates 92 via bearings. The servo motor 91 is fixed to the L-shaped plates 92, and its output end is connected to a drive bevel gear. The bidirectional screw 9 is equipped with a transmission bevel gear 93. The drive bevel gear and the transmission bevel gear 93 mesh to drive the bidirectional screw 9 and drive the transverse scraper 401 to move relative to each other. Furthermore, there are two bidirectional screws 9, and the synchronous rotation of the two bidirectional screws 9 is controlled by two servo motors 91 electrically connected to the central control unit, so that the two transverse scrapers 401 can move synchronously relative to each other.

[0038] Further, see Figure 13 The two ends of the transverse scraper 401 are threadedly connected to the bidirectional screw 9 through the moving part 403. The moving part 403 is fixed on the transverse scraper 401 to facilitate the stable movement of the transverse scraper 401. In order to improve the relative movement stability of the transverse scraper 401, a limiting rod can also be set on the moving frame to further limit the horizontal movement of the transverse scraper 401.

[0039] Further, see Figure 15 The vertical section of the longitudinal scraper 402 is a right-angled triangle or a right-angled trapezoid. The vertical surface of the longitudinal scraper 402 is slidably connected to the two end faces of the transverse scraper 401 and is slidably sealed by a sealing strip. This makes it difficult for water at the bottom of the pit 10 to leak out from both sides of the transverse scraper 401 during the movement of the transverse scraper 401, which can effectively improve the drainage efficiency of the pit 10.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
