Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to a control device for water ingress into the elevator pit. Background Technology

[0002] The section of the hoistway below the lowest floor served by the elevator car is called the pit. It contains buffers, elevator stop switches, hoistway light switches, power outlets, and lighting. One strict requirement for pit operations is that water must not accumulate. Therefore, if water accumulation occurs, appropriate control devices are needed to prevent it from happening in a timely manner.

[0003] Existing patent number CN102372207A proposes an elevator pit water level detection device and its detection and processing method, which can perform three sets of water level detection and processing in the elevator pit. It can effectively reduce the damage and corrosion of escalator equipment and reduce personal injury to passengers. However, when dealing with the problem of water accumulation in the pit caused by the continuous injection of water from broken water pipes or external water leakage, not only does it require the water pump to work continuously, resulting in excessive power consumption, but it also requires controlling the intensity of water pump operation to prevent the water pump from running dry, water discharge after pumping, and cleaning and maintenance of sensors, which leads to inconvenience in use.

[0004] There is a lack of existing technologies for using devices to treat accumulated water. However, using devices to treat water has advantages such as energy saving, high efficiency, and simple maintenance. Therefore, there is an urgent need for a control device for water ingress into elevator pits to solve the above problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a control device for water ingress into the elevator pit, which has the following beneficial effects:

[0018] 1. The control device for water ingress into the elevator pit uses a sealing mechanism. The impact force of the water flow drives the sealing mechanism to operate. After the water flows in, the silicone pad is automatically adjusted to the water injection position. Then, the water pressure inflates the silicone pad to seal the water inlet. This sealing method directly prevents water accumulation in the pit. The device does not use electricity, avoiding electrical leakage and other problems, and also facilitates maintenance.

[0019] 2. The control device for water ingress into the elevator pit, through the fan-shaped arrangement of the sealing plate and other structures, allows the sliding plate B to move in a wider range of angles, enabling the silicone pad to block water inflow from different angles (such as different areas like the ground and walls), thus improving the effectiveness of preventing water accumulation.

[0020] 3. The water inlet control device for the elevator pit connects the drain pipe to the water pump. After the water inlet problem is resolved, the drain pipe is used to pump out the water inside and around the base. With the help of the sealing mechanism, the water pump can pump out a fixed amount of water without causing water accumulation, thus reducing energy consumption and avoiding drainage problems.

[0021] 4. The control device for water inlet in the elevator pit, through the setting of the power mechanism, uses the buoyancy and thrust of the water flow to drive the rotation of the sealing mechanism, thereby causing the sealing plate to rotate periodically around the water inlet cylinder to find the water inlet, improving the protection range of the sealing mechanism and the effect of preventing water accumulation. Moreover, the realization of this function does not utilize electricity and has the same advantages as the sealing mechanism.

[0022] 5. The control device for water inlet in the elevator pit, through the setting of connecting plate B, when the gear cylinder rotates to correspond with the water inlet, uses the impact force and thrust of the water flow to drive the rotation of the rotating cylinder, thereby automatically limiting the connecting plate B, ensuring that the sealing mechanism can find the water inlet and implement the sealing function, improving the stability of the device and improving the effect of preventing water accumulation.

[0023] 6. The control device for water inlet in the elevator pit, through the setting of the magnetic block, realizes the automatic blocking of the water flow by the blocking mechanism when the water is injected, and the automatic reset of the blocking mechanism after the water is discharged, which improves the automation level of the device and makes the device more convenient to use.

[0024] 7. The control device for water ingress into the elevator pit, through the setting of the telescopic mechanism, automatically drives the sealing mechanism to extend when the sealing mechanism rotates, further expanding the protection range of the sealing mechanism and the effect of preventing water accumulation. It also has an automatic reset function, which facilitates the use of the device. Moreover, the realization of this function does not utilize electricity and has the same advantages as the sealing mechanism.

[0025] 8. The control device for water inlet in the elevator pit, through the setting of the cleaning mechanism, uses the automatically generated air pressure flow when the sealing mechanism rotates to scrape and clean the opening of the water inlet B, avoiding the problem of dirt clogging the water inlet B and causing the device to malfunction. The setting of the cleaning mechanism demonstrates the versatility of the device. When the device is in operation, it will produce various movement changes such as rotation, up and down movement, and left and right movement. Technicians can freely add mechanisms with their own knowledge to achieve more functions and have the potential to provide various protections for the pit. Attached Figure Description

[0035] 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.

[0036] Please see Figure 1-8The control device for water ingress into the elevator pit includes a power mechanism 1, a sealing mechanism 2, a drainage mechanism 3, a telescopic mechanism 4, and a cleaning mechanism 5. The sealing mechanism 2 and drainage mechanism 3 are both mounted on the power mechanism 1, while the telescopic mechanism 4 and cleaning mechanism 5 are both mounted on the sealing mechanism 2. The drainage mechanism 3 includes a base 301. The power mechanism 1 includes a gear cylinder 107. The top surface of the base 301 is fixedly connected to the gear cylinder 107 via a flange bearing. The base 301 has a hollow interior and holes along its top surface on the outer edge of the water ingress cylinder 101. The sealing mechanism 2 includes a connecting rod 201, which is fixedly connected to the outer right wall of the gear cylinder 107. A sleeve 202 is fitted into the outer wall of the connecting rod 201. A sealing plate 203 is fixedly connected to the end of the sleeve 202 away from the gear cylinder 107. Both the front and rear sides of the plate 203 are fixedly connected to sealing side plates 204. A flexible hose 205 is fixedly connected to the right side of the sealing plate 203. The end of the flexible hose 205 away from the sealing plate 203 is fixedly connected to the slide plate A206. A groove 7 is opened on the right side of the slide plate A206 on the corresponding side of the two sealing side plates 204. A slider 207 is fitted into the inner wall of the groove 7. The slider 207 is cross-shaped and a spring B208 is fixedly connected to its left side. The end of the spring B208 away from the slider 207 is fixedly connected to the silicone pad 2010. A slide plate B209 is fixedly connected to the side of the silicone pad 2010 near the slide plate A206. The slide plate B209 fits tightly with the slide plate A206. An airbag 2020 is fixedly connected inside the base 301. The inside of the silicone pad 2010 is hollow. Furthermore, it is connected to the inside of the airbag 2020 via the connecting pipe 2011. The sealing plate 203, sealing side plate 204, sliding plate A206, and sliding plate B209 are all fan-shaped plates. First, a groove is opened on the bottom surface and the base 301 is placed in it. When the sliding plate A206 corresponds to the water inlet, the impact force of the water flow is applied to the sliding plate A206, and the hose 205 is compressed, causing the sliding plate A206 to adhere to the sealing plate 203. When the sliding plate A206 moves towards the hose 205, it disengages from the sliding plate B209, and the sliding plate B209 slides downwards under its own weight. When the sliding plate B209 slides to correspond to the water inlet, the impact force of the water flow is applied to the silicone pad 2010, and the spring B208 is deformed, causing the sliding plate B209 to move towards the sliding plate A206 and adhere to it. The system works by using water pressure to compress the airbag 2020, which in turn positions the slide plate B209 to align with the water inlet. The air pressure then compresses the airbag 2020, injecting air into the silicone pad 2010 through the connecting pipe 2011. The silicone pad 2010 inflates and seals the water inlet, preventing water from continuously flowing into the pit. The sealing mechanism 2 operates using the impact of the surging water flow. After water enters, it automatically adjusts the silicone pad 2010 to the water inlet position and then uses water pressure to inflate it, sealing the inlet. This sealing method directly prevents water accumulation in the pit. Furthermore, the device is not electrically powered, avoiding electrical leaks and facilitating maintenance.The fan-shaped arrangement of the sealing plate 203 and other structures allows for a wider range of angles in the movement trajectory of the skateboard B209, enabling the silicone pad 2010 to effectively block water inflows from different angles (such as on the ground and walls), thus improving the water-proofing effect.

[0037] A drain pipe 302 is fixedly connected to and connected to the left side of the base 301. The drain pipe 302 is connected to the water pump. After the water injection problem is solved, the drain pipe 302 is used to extract the water inside and around the base 301. With the setting of the sealing mechanism 2, the water pump needs to extract a fixed amount of water without the problem of water accumulation, which reduces energy consumption and avoids drainage problems.

[0038] The power mechanism 1 also includes a water inlet cylinder 101, which is fixedly connected to the center of the top surface of the base 301. The bottom surface of the water inlet cylinder 101 is hollow. A support column 102 is fixedly connected to the top surface of the base 301 at the center of the water inlet cylinder 101. The support column 102 is a frustum shape, and a water inlet hole A6 is opened on the outer wall of the support column 102. The water inlet hole A6 has a Y-shaped cross-section and communicates with the base 301. A spiral rod 103 is fixedly connected to the center of the top of the support column 102. A spiral groove is opened on the outer wall of the spiral rod 103. A telescopic disc 104 is fitted onto the outer wall of the spiral rod 103. The outer wall of the telescopic disc 104 is fitted into the inner wall of the water inlet cylinder 101. The inner wall of the telescopic disc 104 has a cylindrical protrusion that fits into the spiral groove on the outer wall of the spiral rod 103. A spring A105 is fixedly connected to the top surface of the telescopic disc 104. The end of the spring A105 away from the telescopic disc 104 is fixedly connected to the inner wall of the top surface of the water inlet cylinder 101. A collar 106 is fitted onto the outer wall of the water inlet cylinder 101. Magnets are fixedly installed inside the right side of both the telescopic disc 104 and the collar 106. They attract each other. Both the inner wall of the toothed cylinder 107 and the outer wall of the collar 106 have toothed grooves that mesh with each other. When the water level in the pit rises with the water flow, the water flows through the base 301 and the water inlet A6 into the water inlet cylinder 101, pushing the telescopic disc 104 to rise. Simultaneously, the telescopic disc 104 rotates along the spiral groove on the outer wall of the spiral rod 103. As the telescopic disc 104 rotates, it drives the collar 106 to rotate via magnetic force. The collar 106, through its meshing with the toothed cylinder 107, drives the toothed cylinder 107 to rotate. The toothed cylinder 107... The insertion relationship between the connecting rod 201 and the sleeve 202 drives the sealing plate 203 to rotate, causing the sealing plate 203 to rotate periodically around the water inlet cylinder 101 to find the water inlet. Through the setting of the power mechanism 1, the buoyancy and thrust of the water flow are used to drive the rotation of the sealing mechanism 2, thereby causing the sealing plate 203 to rotate periodically around the water inlet cylinder 101 to find the water inlet, improving the protection range and the effect of preventing water accumulation of the sealing mechanism 2. Moreover, the realization of this function does not utilize electricity and has the same advantages as the sealing mechanism 2.

[0039] A toothed ring 108 is fixedly connected to the top surface of the water inlet cylinder 101. The top surface of the toothed ring 108 has a toothed groove. A fixing plate 2012 is fixedly connected to the top of the side of the sealing side plate 204 near the toothed cylinder 107. A support column 2013 is fixedly connected to the top surface of the fixing plate 2012. A rotating column 2014 is fixedly connected to the support column 2013. A rotating cylinder 2015 is fitted into the outer wall of the rotating column 2014. A connecting plate B2017 is fixedly connected to the side of the rotating cylinder 2015 near the toothed cylinder 107. The bottom surface of the connecting plate B2017 has gear teeth that are compatible with the toothed groove of the toothed ring 108. A connecting plate A2016 is fixedly connected to the side of the rotating cylinder 2015 away from the toothed cylinder 107. A hemispherical block 2018 is fixedly connected to the bottom surface of the end of the connecting plate A2016 away from the rotating cylinder 2015. The hemispherical block 2018 is located between the sealing plate 203 and the sliding plate A. Between 206, when the sliding plate A206 is pushed by the water flow towards the sealing plate 203, it pushes the sliding plate A206 to contact the hemispherical block 2018 and pushes the hemispherical block 2018 to rise. After the hemispherical block 2018 rises, it drives the rotating cylinder 2015 to rotate in the opposite direction. The connecting plate B2017 contacts the toothed ring 108 as the rotating cylinder 2015 rotates. The engagement of the gear teeth with the toothed ring 108 restricts the rotation of the sealing plate 203, thereby restricting the rotation of the sealing mechanism 2. Through the setting of the connecting plate B2017, when the toothed cylinder 107 rotates to correspond with the water inlet, the water flow impact force and thrust drive the rotating cylinder 2015 to rotate, thereby automatically limiting the connecting plate B2017, ensuring that the sealing mechanism 2 can find the water inlet and implement the sealing function, improving the stability of the device and improving the effect of preventing water accumulation.

[0040] The sealing side plate 204 located on the rear side has a movable groove 9 inside. An air inlet 10 is located at the bottom of the back of the movable groove 9. A magnet 2019 is fitted into the inner wall of the movable groove 9. The magnet 2019 magnetically attracts the sliding plate B209. When the sliding plate B209 descends, the magnet 2019 slides within the sliding groove 7 due to the magnetic force. When the water pump draws water out of the base 301, the telescopic disc 104 loses the thrust of the water flow, and the spring A105 rebounds, causing the telescopic disc 104 to descend. Simultaneously with the descent of the telescopic disc 104… The blocking mechanism 2 rotates in the opposite direction. When the blocking mechanism 2 rotates in the opposite direction, water or air is injected into the slide groove 7 through the air inlet 10. The injection of water and air pushes the magnet block 2019 to rise, and then the slide plate B209 is pulled up together by magnetic force, thereby realizing the reset of the slide plate B209. By setting the magnet block 2019, the blocking mechanism 2 can automatically block the water flow when water is injected, and automatically reset the blocking mechanism 2 after the water is discharged, which improves the automation level of the device and makes the device more convenient to use.

[0041] The telescopic mechanism 4 includes a water inlet cylinder A401. The lower half of the slide plate A206 is hollow and connected to the hose 205. A water inlet hole B8 is provided at the bottom of the front of the front sealing side plate 204. The water inlet hole B8 penetrates the front of the slide plate A206 and connects to the interior of the slide plate A206. The side of the connecting rod 201 away from the toothed cylinder 107 is hollow and connected to the hose 205. The bottom surface of the connecting rod 201 near the toothed cylinder 107 is fixedly connected to and connected to the water inlet cylinder A401. A bellows 402 is fixedly connected and communicated with the side of the gear cylinder 107. A connecting post 403 is fixedly connected to the side of the bellows 402 away from the water inlet cylinder A401. The connecting post 403 is fixedly connected to the sealing plate 203. A magnet is provided inside the sleeve 202 and attracts the gear cylinder 107. When the connecting rod 201 rotates as the telescopic disc 104 rises, the rotating post 2014 injects water or air into the slide plate A206 through the water inlet hole B8 while rotating with the connecting rod 201. Then, water or air is injected into the slide plate A206 through the soft... Pipe 205, sleeve 202, connecting rod 201, and water inlet cylinder A401 are injected into bellows 402. The bellows 402 expands after being inflated with air and water, pushing the sealing mechanism 2 away from the toothed cylinder 107. When slide plate A206 is impacted by the water flow and moves closer to the sealing plate 203, slide plate A206 disengages from its correspondence with the water inlet B8 and is sealed by the rotating column 2014, preventing water or air from escaping from the bellows 402. When the water in the pit is pumped out, slide plate A206 resets. Corresponding to the water inlet B8, the water and air inside the bellows 402 are squeezed out through the magnetic connection between the sleeve 202 and the toothed cylinder 107, thereby resetting the sealing mechanism 2. Through the setting of the telescopic mechanism 4, the sealing mechanism 2 is automatically extended when it rotates, further expanding the protection range of the sealing mechanism 2 and the effect of preventing water accumulation. It also has the function of automatic reset, which facilitates the use of the device. Moreover, the realization of this function does not utilize electricity and has the same advantages as the sealing mechanism 2.

[0042] The cleaning mechanism 5 includes multiple protrusions 501, which are fixedly connected to the outer wall of the bottom end of the toothed cylinder 107 at equal intervals. A cylinder 502 is fixedly connected to the top right side of the base 301. The cylinder 502 is hollow inside and has a hole on its left side. A piston 504 is fitted into the inner wall of the cylinder 502. A piston rod 505 is fixedly connected to the side of the piston 504 near the toothed cylinder 107. The piston rod 505 corresponds to the position of the protrusions 501. A spring C503 is fixedly connected to the side away from the gear cylinder 107. A slide cylinder 506 is fixedly connected to the front of the sealing side plate 204 above the water inlet B8. The bottom surface of the slide cylinder 506 is hollowed out and a slide rod 507 is fitted inside. A scraper 508 is fixedly connected to the bottom surface of the slide rod 507. The scraper 508 is in a close fit with the sealing side plate 204. The cylinder 502 and the slide cylinder 506 are connected to each other through a connecting pipe 2011. When the gear cylinder 107 rotates, it passes through... The pressure applied when the protrusion 501 contacts the piston rod 505, and the rebound of the spring C503 after the piston rod 505 disengages from the protrusion 501, drive the continuous compression and extraction of air, thereby driving the slide rod 507 in the slide cylinder 506 connected by the connecting pipe 2011 to slide back and forth. When the slide rod 507 slides back and forth, the scraper 508 scrapes and blocks the opening of the water inlet hole B8 on the side plate 204. Through the setting of the cleaning mechanism 5, the flow of automatically generated air pressure is used when the blocking mechanism 2 rotates to scrape and clean the opening of the water inlet hole B8, avoiding the problem of dirt clogging the water inlet hole B8 and causing the device to malfunction. Moreover, the setting of the cleaning mechanism 5 demonstrates the versatility of the device. When the device is in operation, it will produce various movement changes such as rotation, up and down movement and left and right movement. Technicians can freely add mechanisms with their own knowledge to achieve more functions and have the potential to provide various protections for the pit.

[0043] In use, S1, firstly, a groove is made on the bottom surface and the base 301 is placed in it. When the slide plate A206 corresponds to the water inlet, the impact force of the water flow is applied to the slide plate A206. The hose 205 is compressed under force, causing the slide plate A206 to adhere to the sealing plate 203. When the slide plate A206 moves towards the hose 205, it disengages from the slide plate B209. The slide plate B209 slides downwards under its own weight. When the slide plate B209 slides to correspond to the water inlet, the water flow impacts... Force is applied to the silicone pad 2010, and the spring B208 deforms under the force, causing the slide plate B209 to move towards and fit against the slide plate A206, thereby restricting the position of the slide plate B209 to correspond with the water inlet. Then, the water pressure squeezes the airbag 2020, and the air in the airbag 2020 is injected into the silicone pad 2010 through the connecting pipe 2011. After the silicone pad 2010 is inflated, it blocks the water inlet, thereby preventing water from continuously flowing into the bottom pit.

[0044] S2, when the water level in the pit rises with the water flow, the water flow is injected into the water inlet cylinder 101 through the base 301 and the water inlet hole A6, pushing the telescopic disc 104 to rise. While the telescopic disc 104 is rising, it rotates along the spiral groove on the outer wall of the spiral rod 103. When the telescopic disc 104 rotates, it drives the collar 106 to rotate through magnetic force. The collar 106 drives the gear cylinder 107 to rotate through meshing with the gear cylinder 107. The gear cylinder 107 drives the sealing plate 203 to rotate through the fitting relationship between the connecting rod 201 and the sleeve 202, so that the sealing plate 203 rotates periodically around the water inlet cylinder 101 to find the water inlet.

[0045] S3, when the slide plate A206 is pushed by the water flow to approach the sealing plate 203, it pushes the slide plate A206 to contact the hemispherical block 2018 and pushes the hemispherical block 2018 to rise. After the hemispherical block 2018 is raised, it drives the rotating drum 2015 to rotate in the opposite direction. The connecting plate B2017 contacts the toothed ring 108 as the rotating drum 2015 rotates. The engagement of the gear teeth and the toothed ring 108 restricts the rotation of the sealing plate 203, thereby restricting the rotation of the sealing mechanism 2.

[0046] S4, when the slide plate B209 descends, it drives the magnet block 2019 to slide together in the slide groove 7 through magnetic force. When the water pump draws out the water in the base 301, the telescopic disc 104 loses the thrust of the water flow. The spring A105 rebounds and drives the telescopic disc 104 to descend. At the same time as the telescopic disc 104 descends, it drives the sealing mechanism 2 to rotate in the opposite direction. When the sealing mechanism 2 rotates in the opposite direction, water or air is injected into the slide groove 7 through the air inlet 10. The injection of water and air pushes the magnet block 2019 to rise. Then, the slide plate B209 is pulled up together by magnetic force, thereby realizing the reset of the slide plate B209.

[0047] S5, when the connecting rod 201 rotates as the telescopic disc 104 rises, the rotating column 2014, while rotating with the connecting rod 201, injects water or air into the slide plate A206 through the water inlet B8, and then injects it into the bellows 402 through the hose 205, sleeve 202, connecting rod 201 and water inlet cylinder A401. After the bellows 402 is filled with air and water, it expands and pushes the sealing mechanism 2 to move away from the toothed cylinder 107. When the slide plate A206 is impacted by the water flow and moves closer to the sealing plate 203, the slide plate A206 disengages from the water inlet B8 and is sealed by the rotating column 2014, preventing the water or air in the bellows 402 from being discharged. When the water in the pit is pumped out, the slide plate A206 returns to its original position and aligns with the water inlet B8. Then, through the magnetic connection between the sleeve 202 and the toothed cylinder 107, the water and air in the bellows 402 are squeezed out, realizing the reset of the sealing mechanism 2.

[0048] S6, when the gear cylinder 107 rotates, the pressure applied by the contact between the protrusion 501 and the piston rod 505, and the rebound of the spring C503 after the piston rod 505 disengages from the protrusion 501, drive the continuous compression and injection of air, thereby driving the slide rod 507 in the slide cylinder 506 connected by the connecting pipe 2011 to slide back and forth. When the slide rod 507 slides back and forth, the scraper 508 scrapes and blocks the opening of the water inlet hole B8 on the side plate 204.
