Description

Technical Field

[0001] This invention belongs to the field of gate equipment, specifically a microwave de-icing device for gates. Background Technology

[0002] As a core control component of infrastructure such as water conservancy projects, hydropower stations, and water supply and drainage systems, the operational stability of sluice gates directly affects the realization of key functions such as water conservancy scheduling, flood control and drainage, and water supply security. In the low-temperature environment of winter, ice easily forms on the water-facing surface, gate groove slide, and water-stop rubber of sluice gates. As the temperature drops, the ice layer continues to thicken and harden, bringing multiple safety hazards and technical challenges to sluice gate operation. When the ice thickness exceeds a critical value, it leads to a significant increase in the resistance to opening and closing the sluice gate. This can cause overload of the hoist and a surge in energy consumption, or even cause the sluice gate to jam and fail to open or close normally. In extreme cases, the compressive force generated by the expansion of the ice layer can damage the sluice gate structure, seals, or gate groove concrete, seriously affecting the normal operation of water conservancy projects and even causing safety accidents. Currently, sluice gate de-icing generally uses two methods: manual ice scraping with ice shovels and blowtorch de-icing. However, these methods have the following drawbacks:

[0003] Manual ice removal using ice scrapers has several drawbacks: incomplete ice removal, high resistance to opening and closing gates due to ice, and a high risk factor. On the other hand, ice removal using flame guns is slow, can easily damage gates and waterstops, and is also dangerous to operate manually. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention utilizes microwaves generated by a microwave de-icing device to melt ice on the surface, avoiding the dangers and potential damage to gates associated with manual de-icing and blowtorch de-icing. Simultaneously, an ice-breaking head is installed at the bottom of the moving plate. Driven by a motor, the moving plate reciprocates longitudinally, causing the ice-breaking head to continuously impact the ice surface, achieving physical ice breaking. This combination of microwave de-icing and physical ice breaking improves the speed and efficiency of ice melting.

[0019] This invention features an ice-breaking head at the bottom of a movable plate and a float at the top. The ice-breaking head physically breaks up the ice surface, while the float monitors the melting process as the movable plate rotates, preventing water from contacting the microwave ice melter and thus protecting it.

[0020] In this invention, when the moving plate is longitudinally limited by the side slider, the rotation of the central gear can drive the moving plate to move longitudinally, thus achieving physical ice breaking. When the side slider is fixed to the limiting plate, the rotation of the central gear can drive the moving plate to rotate, thus converting the auxiliary ice breaking mode into the ice melting status monitoring mode, which is convenient to use.

[0021] This invention utilizes the repulsive force generated by an electromagnet on a magnetic block to cause a locking rod to engage with the locking groove, thus fixing the side slider to the housing. This allows the side slider to longitudinally limit the movement of the moving plate. Conversely, when the electromagnet attracts the magnetic block, a push rod moves outward, pushing the locking plate into the square locking groove via a rotating plate. This engages and fixes the side slider to the central gear, facilitating the switching between longitudinal and rotational movement modes and making it convenient to use. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1, by Figures 1-10 The present invention relates to a microwave de-icing device for gates, comprising a housing 1, a microwave de-icing device 2 installed at the bottom of the inner cavity of the housing 1, a power supply and a controller 3 installed inside the housing 1, a drive motor 4 installed on one inner wall of the housing 1, the output shaft of the drive motor 4 extending through to the outside of the housing 1, and an auxiliary ice-breaking mechanism 5 installed at one end of the output shaft of the drive motor 4.

[0037] The microwave ice melter 2 consists of a microwave generator at the top and a microwave transmission device at the bottom. The microwave generator is mainly composed of a magnetron, which converts electrical energy into microwaves. The microwave transmission device is mainly composed of a microwave antenna, which transmits microwaves to the ice that needs to be melted with minimal loss.

[0038] The auxiliary ice-breaking mechanism 5 includes a central gear 502 fixedly installed at the end of the output shaft of the drive motor 4. Limiting plates 501 are symmetrically installed on both sides of the central gear 502. A square slot 503 is provided in the center of the limiting plate 501 on the side away from the housing 1. Two snap-fit ​​slots 6 are provided on one side of the housing 1. The two snap-fit ​​slots 6 are symmetrically arranged on both sides of the output shaft of the drive motor 4. An ice-breaking detection component 504 is provided on the outer side of the central gear 502.

[0039] The ice-breaking detection component 504 includes a movable plate 5041. An internal groove 5042 is formed inside the movable plate 5041. The movable plate 5041 is located between two limiting plates 501. A toothed plate 5043 is installed on one inner wall of the internal groove 5042, meshing with a central gear 502. An ice-breaking head 5045 is installed at the bottom of the movable plate 5041. An ice-melting detection component is provided at the top of the movable plate 5041. A fixing control component 505 is installed on the outer side of the movable plate 5041. The two sides of 41 are symmetrically provided with side grooves 5044, wherein the side groove 5044 away from the toothed plate 5043 extends into the inner side of the inner groove 5042. The microwave ice melter 2 can melt the ice surface with microwaves. At the same time, the bottom of the moving plate 5041 is provided with an ice breaking head 5045. The moving plate 5041 is driven to move longitudinally and reciprocate by the drive motor 4, which can make the ice breaking head 5045 continuously impact the ice surface to achieve physical ice breaking. The combination of microwave ice melting and physical ice breaking improves the ice melting efficiency.

[0040] The de-icing detection component includes a guide semicircular block 5046 fixedly installed on the top of a movable plate 5041. Two rope grooves 5047 are formed on the top of the movable plate 5041, symmetrically arranged on both sides of the guide semicircular block 5046. A pull rope 5048 is provided on the outer side of the guide semicircular block 5046, with both ends of the pull rope 5048 passing through the two rope grooves 5047 and entering the inner side of the inner groove 5042. A float 5049 is installed at one end of the pull rope 5048. The other end of 5048 is wound and connected to the winding roller 50410. A rotation sensor is installed on the winding roller 50410. An ice-breaking head 5045 is provided at the bottom of the moving plate 5041, and a float ball 5049 is provided at the top of the moving plate 5041. The ice-breaking head 5045 physically breaks the ice surface. After the moving plate 5041 rotates, the float ball 5049 can detect the ice melting status and prevent water from contacting the microwave ice melter 2, thereby protecting the microwave ice melter 2.

[0041] The fixed control component 505 includes a side slider 5051 that is slidably connected to the side slide groove 5044. When the side slider 5051 longitudinally limits the moving plate 5041, the rotation of the central gear 502 can drive the moving plate 5041 to move longitudinally, thus achieving physical ice breaking. When the side slider 5051 is locked to the limiting plate 501, the rotation of the central gear 502 can drive the moving plate 5041 to rotate, thus converting the auxiliary ice breaking mode into the ice melting status monitoring mode for easy use. A connecting plate 5052 is installed between the two side sliders 5051. The connecting plate 5052 is located on the side of the limiting plate 501 away from the housing 1. A gear protection component 5053 is installed on the side slider 5051 away from the toothed plate 5043. A locking control component 5054 is provided on the side of the two side sliders 5051 away from each other. A central fixing component 5055 is installed on the connecting plate 5052.

[0042] The gear protection component 5053 includes a protection plate 50531 fixedly installed on the side slider 5051. The protection plate 50531 is located inside the inner groove 5042. The protection plate 50531 has a protection groove 50532. The central gear 502 is located inside the protection groove 50532. The winding roller 50410 is installed on the protection plate 50531.

[0043] The snap-fit ​​control component 5054 includes a side cylinder 50541 symmetrically mounted on two side sliders 5051, located away from each other. A movable plate 50542 is movably mounted inside the side cylinder 50541. Rod slots are provided at both ends of the side cylinder 50541. A locking rod 50544 is fixedly mounted on the side of the movable plate 50542 closest to the housing 1. The locking rod 50544 corresponds to the snap-fit ​​slot 6. A push rod 50545 is fixedly mounted on the side of the movable plate 50542 away from the housing 1. A first spring 50543 is symmetrically mounted on both sides of the movable plate 50542. The end of the first spring 50543 is fixedly connected to the inner wall of the end of the side cylinder 50541. A magnet 50546 is mounted on the movable plate 50542. An electromagnet 50547 is mounted on the inner wall of the end of the side cylinder 50541 away from the housing 1.

[0044] The central fixing component 5055 includes a central box 50551 fixedly installed in the middle of the connecting plate 5052. A retaining plate 50552 is movably installed inside the central box 50551, corresponding to a square retaining groove 503. A second spring 50553 is symmetrically installed on the side of the retaining plate 50552 away from the housing 1. One end of the second spring 50553 is fixedly connected to the inner wall of the end of the central box 50551. Side grooves 50554 are symmetrically opened on both sides of the central box 50551. A rotating plate 50555 is symmetrically hinged on both sides of the retaining plate 50552. A guide groove 50556 is opened on the inner side of the rotating plate 50555. A guide slide 50557 is slidably arranged on the inner side of the guide groove 50556 and is fixedly installed on the connecting plate 5052. The guide slide 50557 is arranged parallel to the connecting plate 5052, and the end of the push rod 50545 contacts the surface of the guide slide 50557 near the connecting plate 5052. When the electromagnet 50547 generates a repulsive force on the magnetic block 50546, the locking rod 50544 is inserted into the locking groove 6, fixing the side slider 5051 to the housing 1, so that the side slider 5051 can longitudinally limit the moving plate 5041. When the electromagnet 50547 generates an attractive force on the magnetic block 50546, the push rod 50545 moves outward, and the rotating plate 50555 pushes the locking plate 50552 into the square locking groove 503, locking and fixing the side slider 5051 and the central gear 502, which facilitates switching between longitudinal and rotational movement modes and is convenient to use.

[0045] Working principle: During use, a sliding bracket is set on the gate, and the housing 1 is installed on the bracket. The height and horizontal position of the housing 1 can be adjusted through the bracket.

[0046] The microwave ice melter 2 is powered by the power supply and the controller in the controller 3. At the same time, the power supply and the controller in the controller 3 control the switching of the microwave ice melter 2. The microwave ice melter 2 includes a microwave generator and a microwave transmission device. In use, the microwave generator is controlled to generate microwaves. The microwave generator is mainly a magnetron. The magnetron is of industrial grade and its power is greater than 3000W. The 3000W high-power magnetron can be replaced by three 1000W low-power magnetrons. Three 1000W low-power magnetrons can produce the same effect as one 3000W high-power magnetron. However, three 1000W low-power magnetrons are cheaper than one 3000W high-power magnetron, which can save costs. Then, the microwaves are transmitted to the ice surface through the microwave transmission device, which is generally a microwave antenna. The ice is melted by microwave energy.

[0047] During microwave de-icing, a positive current is supplied to the electromagnet 50547, causing the electromagnet 50547 to generate a repulsive force on the magnetic block 50546, thereby pushing the locking rod 50544 to move towards one side of the housing 1, so that the locking rod 50544 is locked into the locking groove 6, thereby fixing the side slider 5051 and the connecting plate 5052, so that the two side sliders 5051 can longitudinally limit the moving plate 5041;

[0048] Then, the drive motor 4 is turned on, and the output shaft of the drive motor 4 is controlled and driven to rotate in both directions, thereby driving the middle gear 502 to rotate in both directions. Since the middle gear 502 is meshed with the toothed plate 5043, it drives the moving plate 5041 to move longitudinally back and forth, causing the ice breaking head 5045 to move longitudinally back and forth, continuously generating impact force on the ice surface, breaking the ice surface, and improving the ice melting effect.

[0049] When the ice surface melts and the water level needs to be checked, after the control center gear 502 and the moving plate 5041 return to their original positions, a reverse current is applied to the electromagnet 50547, causing the electromagnet 50547 to attract the magnetic block 50546, which drives the push rod 50545 to move away from the housing 1 and disengages the locking rod 50544 from the locking groove 6. The movement of the push rod 50545 generates a thrust on the rotating plate 50555, causing the rotating plate 50555 to rotate around the guide slide 50557 and push the locking plate 50552 to move towards the housing 1, so that the locking plate 50552 is locked into the square locking groove 503.

[0050] Then, the drive motor 4 is turned on, driving the central gear 502 to rotate 180 degrees. Because the locking plate 50552 engages with the square slot 503, the side slider 5051 rotates as a whole, which in turn drives the moving plate 5041 to rotate 180 degrees. During use, the housing 1 is adjusted to a position 20cm-50cm from the ice surface by the microwave ice melter 2. At this time, the housing 1 and the moving plate 5041 rotate 180 degrees, and the guide semicircular block 5046 contacts the ice surface. During water depth detection, the movable plate 5041 is rotated 180 degrees. At this time, the water submerges the float 5049, generating buoyancy on the float 5049, causing it to float on the water surface. The water also exerts a pulling force on the float 5049, which pulls the winding roller 50410 to rotate. The rotation sensor on the winding roller 50410 detects the circumferential distance of the circumferential surface of the winding roller 50410, thereby detecting the water depth and preventing water from contacting the microwave ice melter 2 and causing damage to the microwave ice melter 2.
