Description

Technical Field

[0001] This invention relates to the field of equipment related to water conservancy projects, and in particular to a friction-de-icing antifreeze water conservancy gate. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures, used to intercept water flow, control water levels, regulate flow, and discharge silt and floating debris. However, in high-latitude reservoirs, especially in winter, ice formation can cause the gates and dam body to freeze together, particularly at the gate edges. Simultaneously, water seeps to the other side of the gate and freezes, significantly increasing the ice-covered area and making the gate unable to open.

[0003] Existing gate antifreeze methods can be roughly divided into the following types: aeration de-icing, vibration de-icing, and heating de-icing. Among them, aeration de-icing and heating de-icing require the installation of corresponding equipment at or inside the gate, and a series of issues such as power supply need to be considered. Vibration de-icing, on the other hand, will cause the gate to vibrate. Since the gate is in a low temperature state, it will cause fatigue damage to the gate during the vibration de-icing process, and at the same time, it will affect the gate's airtightness. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a friction-induced ice-resistant antifreeze hydraulic gate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A friction-de-icing antifreeze hydraulic gate includes a gate frame, which comprises an upper crossbeam, a lower crossbeam, and a gate slot frame, and further includes:

[0007] The gate assembly, located inside the gate frame, includes a gate body disposed between the upper and lower cross frames and slidably installed in the gate slot frame, an acceleration transmission mechanism disposed at the center above the gate body, sprocket shafts disposed at both ends inside the gate, sprockets mounted on the sprocket shafts, a strip chain assembly fitted on the sprockets, several strip heat transfer plates disposed on one side inside the gate body, fixed vertical rods disposed on both sides inside the gate body, two spring telescopic cylinders disposed on the fixed vertical rods, and two fixed horizontal rods disposed on one side of the fixed vertical rods, wherein the fixed horizontal rods are fixedly connected to the telescopic ends of the spring telescopic cylinders;

[0008] The gate slot antifreeze component is located at the lower end of the side surface of the gate slot frame. It includes a heating box set outside the gate slot frame, with a partition inside that divides the heating box into a heating chamber and a heat transfer chamber. Heat transfer oil is set in the heat transfer chamber. Several heat transfer columns are movably inserted into the partition and are fastened to the partition by studs and nuts and sealed by heat insulation gaskets. Heat dissipation fins are installed at one end of the heat transfer columns and are located in the heat transfer chamber. An electromagnetic induction heating coil is fitted at the other end of the heat transfer columns. A control component is installed at the upper end of the side surface of the gate frame and connected to the electromagnetic induction heating coil.

[0009] The drive assembly, mounted on the upper crossbeam, includes a drive mechanism mounted on the upper crossbeam, a drive shaft located on one side of the drive mechanism and connected thereto, a bevel gear one mounted on one end of the drive shaft, a rope drum located at both ends on one side of the drive shaft, a wire rope wound on the rope drum, wire rope pulleys located on both sides of the center of the upper crossbeam, the wire rope being fitted onto the wire rope pulleys, and a bevel gear four mounted on one end of the shaft of the rope drum.

[0010] The opening and closing adjustment assembly is set on the upper crossbeam. It includes a limiting sleeve shaft that is fitted on the other end of the drive shaft and rotates synchronously with it, bevel gear two and bevel gear three installed on the limiting sleeve shaft, an adjusting bearing installed on one end of the limiting sleeve shaft, and an electric push rod set on the upper crossbeam, the telescopic end of which is connected to the adjusting bearing.

[0011] A closing limit assembly is provided on the door slot frame, which includes a miniature electric actuator mounted above the heating box and a locking pin provided on the miniature electric actuator, which can be inserted into the door slot of the door slot frame.

[0012] Furthermore, the second and third bevel gears are symmetrically distributed on the limiting sleeve shaft and alternately mesh with the fourth bevel gear, while the first bevel gear meshes with the fourth bevel gear.

[0013] Furthermore, the acceleration transmission mechanism includes a drive wheel installed at the center above the gate body, a steel wire rope wound around the drive wheel, a transmission box located behind the drive wheel, an acceleration gear set installed in the transmission box and connected to the shaft of the drive wheel, a transmission gear installed on the sprocket shaft, and a transmission chain fitted on the transmission gear and meshing with the acceleration gear set.

[0014] Furthermore, the strip chain assembly includes a strip chain plate, a rotating engagement member, a pin, and ceramic friction plates. The rotating engagement member is installed at both ends of one side of the strip chain plate and the strip chain plate is assembled by the pin. The ceramic friction plates are evenly installed on the other side of the strip chain plate and are in frictional contact with the strip heat transfer plate.

[0015] Furthermore, the strip chain plate uses a spring telescopic cylinder to push the fixed crossbar, so that the ceramic friction plate and the strip heat transfer plate maintain sufficient friction.

[0016] Furthermore, the volume of the heat-conducting oil inside the heat transfer chamber after heating and expansion is smaller than the volume of the heat transfer chamber.

[0017] Furthermore, the height of the heating box is the same as the height of the gate body after it is closed.

[0018] Furthermore, the strip heat transfer plates are evenly distributed laterally on one side surface inside the gate body, and the strip heat transfer plates are located on the water-facing side of the gate body.

[0019] Beneficial effects

[0020] A friction-cooling ice-resistant antifreeze hydraulic gate manufactured using the technical solution of this invention has the following beneficial effects:

[0021] The antifreeze component for the gate slot in this invention can heat the heat transfer column using the principle of electromagnetic induction heating and use heat transfer oil as a medium for heat transfer, thereby uniformly heating the gate slot frame to remove ice inside the gate slot frame and prevent the gate from failing to close smoothly.

[0022] The gate assembly in this invention can be controlled by the rotation of the steel wire rope to rotate the internal strip chain assembly, thereby causing the ceramic friction plate and the strip heat transfer plate to slide in contact under a certain frictional force. This increases the temperature of the gate's water-facing surface by generating heat through friction, preventing the gate from freezing and removing attached floating ice. Furthermore, the temperature increase is relatively slow, which can effectively prevent the gate body from becoming too hot and causing adverse effects on its material.

[0023] This invention utilizes an opening and closing adjustment component and a closing limit component, which allows operators to easily control the gate and also limits its movement after closure. This makes the gate closure more secure and allows the steel wire rope to be adjusted to keep it taut, thereby ensuring the smooth operation of the internal components of the gate assembly.

[0039] 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.

[0040] Existing devices mostly employ aeration de-icing, vibration de-icing, and heating de-icing methods for sluice gate antifreezing and de-icing operations. While traditional aeration or heating de-icing methods can quickly remove ice from sluice gates, they require the installation of corresponding equipment at the gate, necessitating comprehensive consideration of the gate structure and other issues, making implementation difficult and costly. Vibration de-icing, on the other hand, may cause fatigue damage to the gate itself due to its low temperature. Therefore, we propose a friction-de-icing type antifreezing hydraulic sluice gate. In short, the device includes a gate frame 1, which comprises an upper horizontal frame 11, a lower horizontal frame 12, and a gate slot frame 13, and also includes: a gate assembly. 2. Gate slot antifreeze component 3, drive component 4, opening and closing adjustment component 5, closing limit component 6. The gate component 2 provided in this invention can use the drive component 4 to control the wire rope to reciprocate, thereby driving the internal components to work. In turn, the temperature of the water-facing surface of the gate is increased by frictional heat generation, so that the ice on the gate can be quickly separated from the gate, thereby preventing the gate from freezing. The gate slot antifreeze component 3 uses electromagnetic induction heating to heat the gate slot frame 13, thereby preventing the gate slot frame 13 from freezing and affecting the opening and closing of the gate. This effectively prevents the gate from causing inconvenience due to freezing and ensures the normal operation of the gate in winter.

[0041] This invention provides a friction-de-icing antifreeze hydraulic gate, such as... Figures 1-8 As shown, the gate frame 1 includes an upper horizontal frame 11, a lower horizontal frame 12, and a gate slot frame 13. It also includes a gate assembly 2 located inside the gate frame 1, which includes a gate body 21 disposed between the upper horizontal frame 11 and the lower horizontal frame 12 and slidably installed in the gate slot frame 13, an acceleration transmission mechanism 22 disposed at the center above the gate body 21, sprocket shafts 23 disposed at both ends inside the gate, sprockets 24 mounted on the sprocket shafts 23, a strip chain assembly 25 mounted on the sprockets 24, several strip heat transfer plates 26 mounted on one side inside the gate body 21, fixed vertical rods 27 mounted on both sides inside the gate body 21, two spring telescopic cylinders 28 disposed on the fixed vertical rods 27, and two fixed horizontal rods 29 disposed on one side of the fixed vertical rods 27. The fixed horizontal rods 29 are fixedly connected to the telescopic ends of the spring telescopic cylinders 28.

[0042] In this embodiment of the invention, the acceleration transmission mechanism 22 is connected to the sprocket shaft 23 for transmission, causing the sprocket 24 to drive the strip chain assembly 25 to move. The rotation of the strip chain assembly 25 and the friction between it and the strip heat transfer plate 26 generate heat, increasing the temperature of the strip heat transfer plate 26 and thus increasing the temperature of the gate body 21. The fixed vertical rod 27 inside the gate body 21 is used to support the fixed horizontal rod 29. The fixed horizontal rod 29 is distributed laterally on the upper and lower sides inside the gate body. The elasticity of the spring telescopic cylinder 28 pushes the strip chain assembly 25, causing it to generate greater compression friction with the strip heat transfer plate 26, thereby improving the friction heat generation efficiency.

[0043] In this embodiment of the invention, the strip heat transfer plate 26 is made of aluminum alloy. While ensuring heat transfer efficiency, it can increase the thickness of the gate body 21 at the friction position, avoiding changes in the gate thickness due to long-term use. At the same time, the heat generated by friction is directly transferred to the gate body 21, preventing the local temperature from becoming too high and causing changes in the physical properties of the gate body 21 itself.

[0044] In this embodiment of the invention, the arrangement of the sprocket 24 and the strip chain assembly 25 allows them to make full contact with the strip heat transfer plate 26 while ensuring the stability of the contact, thereby ensuring the efficiency of frictional heat generation.

[0045] The gate slot antifreeze assembly 3 is located at the lower end of the side surface of the gate slot frame 13. It includes a heating box 31 disposed outside the gate slot frame 13, with a partition 32 inside to divide the heating box 31 into a heating chamber 33 and a heat transfer chamber 34, heat transfer oil 35 disposed in the heat transfer chamber 34, several heat transfer columns 36 movably inserted on the partition 32, which are fastened to the partition 32 by studs 361 and nuts 362 and sealed by heat insulation pads 363, heat dissipation fins 364 installed at one end of the heat transfer column 36, which are located in the heat transfer chamber 34, an electromagnetic induction heating coil 37 fitted at the other end of the heat transfer column 36, and a control assembly 38 installed at the upper end of the side surface of the gate frame 1 and connected to the electromagnetic induction heating coil 37.

[0046] In this embodiment of the invention, the electromagnetic induction heating coil 37 is used to quickly heat the heat transfer column 36, and the heat transfer column 36 is made of aluminum alloy, which makes its heat transfer efficiency faster.

[0047] In this embodiment of the invention, heat transfer oil 35 is used as the intermediate heat transfer medium, which allows the gate slot frame 13 to be heated more fully, so that ice can quickly detach from the gate slot frame 13, thereby avoiding the gate slot frame 13 from freezing and affecting the use of the gate.

[0048] In this embodiment of the invention, the heat transfer column 36 can be quickly fixed by using the stud 361 and the nut 362, and the heat insulation pad 363 can be used for sealing to prevent leakage of the heat transfer oil 35.

[0049] The drive assembly 4 is mounted on the upper crossbeam 11 and includes a drive mechanism 41 mounted on the upper crossbeam 11, a drive shaft 42 located on one side of the drive mechanism 41 and connected thereto, a bevel gear 43 mounted on one end of the drive shaft 42, a rope drum 44 located at both ends on one side of the drive shaft 42, a wire rope 45 wound on the rope drum 44, wire rope pulleys 46 located on both sides of the center of the upper crossbeam 11, the wire rope 45 being fitted onto the wire rope pulleys 46, and a bevel gear 47 mounted on one end of the shaft of the rope drum 44.

[0050] In this embodiment of the invention, the drive mechanism 41 uses the transmission of the transmission shaft 42 to control the rotation of the rope drum 44, and then uses the winding of the wire rope 45 to control the opening and closing of the gate body 21 on the one hand, and on the other hand, it can control the internal components to work through the acceleration transmission mechanism 22, and use frictional heat to heat and prevent freezing of the gate body 21.

[0051] The opening and closing adjustment assembly 5 is set on the upper cross frame 11. It includes a limiting sleeve shaft 51 that is fitted on the other end of the transmission shaft 42 and rotates synchronously with it, a second bevel gear 52 and a third bevel gear 53 installed on the limiting sleeve shaft 51, an adjusting bearing 54 installed on one end of the limiting sleeve shaft 51, and an electric push rod 55 set on the upper cross frame 11, the telescopic end of which is connected to the adjusting bearing 54.

[0052] In this embodiment of the invention, the bevel gears 52 and 53 on the limiting sleeve shaft 51 can be used to control them to alternately mesh with the bevel gear 47, thereby adjusting the control mode of the wire rope 45 to facilitate the control and operation of the staff.

[0053] The closing limit assembly 6 is provided on the door slot frame 13. It includes a miniature electric push rod 61 installed above the heating box and a locking pin 62 provided on the miniature electric push rod 61, which can be inserted into the door slot of the door slot frame 13.

[0054] In this embodiment of the invention, the locking pin 62 is used to limit the closure of the gate body 21 after it is closed, ensuring the stability of the gate body 21 closure. At the same time, the drive mechanism 41 can control the rope drum 44 to tighten the wire rope 45, so that the wire rope 45 and the drive wheel 221 maintain sufficient friction to control the normal operation of the internal components of the gate body 21.

[0055] Bevel gear 2 52 and bevel gear 3 53 are symmetrically distributed on the limiting sleeve shaft 51 and alternately mesh with bevel gear 47. Bevel gear 1 43 meshes with bevel gear 47.

[0056] In this embodiment of the invention, the sliding adjustment of the limiting sleeve shaft 51 on the transmission shaft 42 is used to make the bevel gear 2 52 and bevel gear 3 53 alternately mesh with the bevel gear 4, thereby controlling the rotation direction of the two rope drums 44, and thus controlling the operation mode of the wire rope 45.

[0057] The acceleration transmission mechanism 22 includes a drive wheel 221 installed at the center above the gate body 21, a wire rope 45 wound around the drive wheel 221, a transmission box 222 located behind the drive wheel 221, an acceleration gear set 223 installed in the transmission box 222 and connected to the shaft of the drive wheel 221, a transmission gear 224 installed on the sprocket shaft 23, and a transmission chain 225 fitted on the transmission gear 224 and meshing with the acceleration gear set 223.

[0058] In this embodiment of the invention, the multiple turns of the wire rope 45 wrapped around the drive wheel 221 can maintain sufficient friction between the wire rope 45 and the drive wheel 221 after it is taut, thereby ensuring the stability of power transmission. The setting of the acceleration gear set 223 can increase the output speed of the drive wheel 221, thereby increasing the rotation speed of the sprocket 24 and making the efficiency of frictional heat generation higher.

[0059] In this embodiment of the invention, the appendix Figure 2 and attached Figure 3 The acceleration gear set 223 in the diagram is just a simple transmission representation and does not clearly express the acceleration effect, so it is only for reference.

[0060] The bar chain assembly 25 includes a bar chain plate 251, a rotating engagement member 252, a pin 253, and ceramic friction plates 254. The rotating engagement member 252 is installed at both ends of one side of the bar chain plate 251 and is assembled with the bar chain plate 251 by the pin 253. The ceramic friction plates 254 are evenly installed on the other side of the bar chain plate 251 and are in frictional contact with the bar heat transfer plate 26.

[0061] In this embodiment of the invention, by using the rotating engagement member 252, multiple strip chain plates 251 can be arranged into a ring chain, which is then fitted onto the sprocket 24. The height of the chain is fixed by the sprocket 24, and its rotation can be controlled by the sprocket 24. Then, by using the extrusion friction contact between the ceramic friction plate 254 and the strip heat transfer plate 26, the strip heat transfer plate 26 is heated and heat is transferred to the gate body 21 to remove the floating ice attached to the gate body 21 and prevent the gate body 21 from freezing.

[0062] The strip chain plate 251 uses the spring telescopic cylinder 28 to push the fixed crossbar 29, so that the ceramic friction plate 254 and the strip heat transfer plate 26 maintain sufficient friction.

[0063] In this embodiment of the invention, the movement of the fixed crossbar 29 is moved by the spring telescopic cylinder 28, and then the fixed crossbar 29 is used to squeeze the strip chain plate 251, so that the ceramic friction plate 254 and the strip heat transfer plate 26 generate greater friction through compression, thereby improving the efficiency of frictional heat generation.

[0064] The volume of the heat transfer oil 35 installed inside the heat transfer chamber 34 after thermal expansion is smaller than the volume of the heat transfer chamber 34.

[0065] In this embodiment of the invention, after the heat transfer oil 35 is heated, its volume expands as the temperature increases due to the temperature change. In order to avoid the heat transfer oil 35 expanding and pressing on the heat transfer chamber 34, the heat transfer oil 35 will not fill the heat transfer chamber 34, thereby ensuring the safety of the device.

[0066] The height of the heating box 31 is the same as the height of the gate body 21 after it is closed.

[0067] In this embodiment of the invention, the locking pin 62 provided above the heating box 31 can restrict and fix the gate body 21 after it is closed, thereby preventing the height of the gate body 21 from changing when the wire rope 45 is adjusted.

[0068] The strip heat transfer plates 26 are evenly distributed laterally on one side surface inside the gate body 21, and the strip heat transfer plates 26 are located on the water-facing side of the gate body 21.

[0069] In this embodiment of the invention, the strip heat transfer plate 26 is disposed on the inner surface of the water-facing side of the gate body 21, which can ensure that the temperature of the water-facing side rises and prevent the water on the water-facing side from freezing and adhering to the gate body 21, or freezing the gate body 21 and the gate slot frame 13.

[0070] During the implementation of this technical solution, those skilled in the art need to connect all electrical components in this case to the external power supply mechanism, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and complete the electrical connection by referring to the working sequence of each electrical component. The detailed connection method is a well-known technology in the field. The following mainly introduces the working principle and process, and will not explain the electrical control.

[0071] When using this invention in practice: when the gate freezes in winter and it is necessary to open the gate to release water, after receiving the water release order, the staff will carry out de-icing and antifreeze work on the gate a certain time in advance according to the predetermined water release time.

[0072] S1: Control the electric push rod 55 to work, so that bevel gear 2 52 and bevel gear 47 mesh, thereby causing the two rope drums 44 to rotate in the same direction, and control the drive mechanism 41 to work, so as to control the rotation of the rope drum 44 to wind up the wire rope 45. Due to the limit of the locking pin 62, the wire rope 45 is tightened.

[0073] S2: Control the drive mechanism 41 to stop working, and then control the electric push rod 55 to work, so that the bevel gear 3 53 and the bevel gear 47 mesh, thereby causing the two rope drums 44 to rotate in opposite directions, so that the wire rope 45 is transmitted between the two rope drums 44.

[0074] S3; The movement of the wire rope 45 drives the drive wheel 221 to work through friction. Through the transmission of the acceleration gear set 223, the transmission chain 225 drives the transmission gear 224 to work, which in turn drives the sprocket 24 to rotate, causing the strip chain assembly 25 to start rotating. Through the compression of the fixed crossbar 29 by the spring telescopic cylinder 28, the ceramic friction plate 254 on the strip chain plate 251 comes into frictional contact with the strip heat transfer plate 26.

[0075] S4: The ceramic friction plate 254 is pressed and rubbed against the strip heat transfer plate 26, and the strip chain assembly 25 is rotated to raise the temperature of the strip heat transfer plate 26 by frictional heat generation. In turn, the temperature of the gate body 21 is raised by heat transfer, thereby removing the floating ice on the gate body 21 and preventing the gate body 21 from freezing due to water freezing and being unable to open.

[0076] S5: When the time reaches a certain period before the predetermined water release time, the electromagnetic induction heating coil 37 is controlled by the control component 38 to start working. The electromagnetic induction heating is used to heat the heat transfer column 36, and then the heat transfer column 36 itself heats the heat transfer oil 35, thereby increasing the temperature of the heat transfer oil 35. Then, through the heat transfer oil 35, the part of the gate frame 13 in contact with the water is gradually heated, thereby performing de-icing and antifreeze work on the gate frame, preventing the gate body 21 and the gate frame 13 from freezing together due to icing.

[0077] In the specific implementation of this invention, in order to avoid changes in the physical properties of the gate body 21 due to instability, the friction force between the ceramic friction plate 254 and the strip heat transfer plate 26 is limited to a certain range. At the same time, the rotation speed of the strip chain assembly 25 is also limited to a certain range, thereby controlling the efficiency of frictional heat generation and keeping the maximum heat of the gate body 21 in a reasonable range during the heat transfer process, thereby preventing changes in the physical properties of the gate body 21.

[0078] In the specific implementation of this invention, the maximum temperature of the heat transfer oil 35 after being heated is lower than 75°C, so as to avoid changes in the physical properties of the door slot frame 13.

[0079] In summary, this invention provides a friction-de-icing antifreeze hydraulic gate. A steel wire rope 45 controls the opening and closing of the gate body 21. Simultaneously, by adjusting the function of the steel wire rope 45, it drives the internal components of the gate body 21, thereby increasing the water-facing temperature of the gate body 21 through frictional heat generation to remove ice buildup and prevent freezing. Furthermore, electromagnetic heating is used to de-ice and thaw the gate slot frame 13 for a certain period before the gate opens, ensuring the smooth opening and closing of the gate body 21.

[0080] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
