Description

Technical Field

[0001] This utility model relates to the field of gate technology for water conservancy projects, and in particular to an anti-freezing gate device. Background Technology

[0002] In water conservancy projects, sluice gates, as core components for controlling water flow, directly affect the safety of the entire water conservancy system due to their stable operation in winter. This is especially true in cold regions, such as Inner Mongolia, where sluice gates, due to prolonged contact with water, are prone to water accumulation and freezing on their surfaces and structural gaps. This leads to difficulties in opening and closing, decreased sealing performance, and even structural damage. Sluice gates have become a prominent problem restricting the winter operation of water conservancy projects, as detailed below:

[0003] The main body of the gate is usually equipped with a beam grid structure to enhance mechanical performance. However, water is easy to accumulate in the gaps of the beam grid and freezes quickly at low temperatures in winter. The strong adhesion between the ice layer and the beam grid will significantly increase the gate's opening and closing resistance. In severe cases, it may cause overload damage to the drive mechanism, and the expansion of the ice layer may cause irreversible deformation to the beam grid structure.

[0004] Traditional gates have rigid frames that come into direct contact with the sliding grooves of the building. The sliding contact between the gate and the building lacks a dynamic sealing and compensation mechanism. After long-term use, gaps can easily appear due to edge wear or slight displacement of the gate, causing water to leak into the structural gaps and exacerbating the risk of freezing. At the same time, the leaked water will freeze in the sliding groove at low temperatures, further hindering the raising and lowering of the gate. Utility Model Content

[0005] This utility model relates to an anti-icing gate device. Through the synergistic effect of various structures, the anti-icing gate device can effectively prevent the gate body and beam grid from freezing, ensure the smooth opening and closing of the gate, and improve the stability and sealing of the structural connection. It is suitable for water conservancy projects in cold regions.

[0006] This utility model provides an anti-freezing gate device, specifically including: a building, a supporting frame installed on the upper part of the building, the supporting frame having a U-shaped structure, a stabilizing sleeve provided in the middle of the supporting frame, a set of driving mechanisms installed on the inner side of the stabilizing sleeve, a vertical lifting rod inserted between the stabilizing sleeve and the driving mechanism, two symmetrically distributed stabilizing grooves with rectangular structures opened on the upper part of the gate body, a rack installed on the inner side of each stabilizing groove, a gate body installed at the bottom of the lifting rod with bolts, a beam grid provided on the inner side of the gate body, a heater installed on the inner side of the beam grid, the length of the heater corresponding to the inner side of the beam grid.

[0007] Furthermore, a set of vertical sliding grooves is provided on the inner side of the building, and the two sides of the gate body extend into the interior of the sliding grooves respectively.

[0008] Furthermore, the rack has a sawtooth structure, and an elastic frame is installed between the two racks. Each side of the elastic frame has a set of locking teeth that mesh with the rack. An anti-loosening ring is provided on one side of the elastic frame. The rack, elastic frame, and anti-loosening ring cooperate with each other to form an anti-loosening structure.

[0009] Furthermore, a locking nut is installed on one side of the connecting bolts of the gate body and the lifting rod, and one side of the connecting bolt extends into the interior of the anti-loosening ring, with the side of the anti-loosening ring contacting the locking nut.

[0010] The heater has two heating wires on its outer side, which are bent. The gate body has a set of positioning grooves distributed at different positions. The positioning grooves are U-shaped and the heating wires pass through the inside of the positioning grooves.

[0011] Furthermore, a sliding groove is provided on each of the two sides of the gate body. The sliding groove has a rectangular structure. A sealing strip is installed inside the sliding groove. The sealing strip corresponds to the sliding groove. A set of symmetrically distributed positioning rods is provided on one side of the sealing strip. Two sets of symmetrically distributed positioning sleeves are provided on the inner side of the gate body. The positioning rods pass through the inside of the positioning sleeves. A support spring is installed on the outer side of each positioning rod.

[0012] Furthermore, a sealing washer is installed on one side of the gate body, and a sealing plate is installed on one side of the sealing washer. A set of bolt mounting holes are respectively opened at the corners of the gate body, the sealing washer, and the sealing plate. The gate body, the lifting rod, the sealing strip, the positioning rod, the sealing washer, and the sealing plate cooperate with each other to form the gate structure. A positioning groove is opened on one side of the gate body and the sealing plate, and the two sides of the sealing washer extend into the interior of the positioning groove.

[0013] Furthermore, a power cord is provided above the heater, a power connector is provided on one side of the power cord, a plug is installed on one side of the power connector, a clamping cap is installed on the outside of the plug, a pressing ring is provided on the outer side of the plug, and a bolt mounting hole is opened on both sides of the clamping cap.

[0014] This utility model provides an anti-freezing gate device, which has the following beneficial effects:

[0015] In this invention, a sealing gasket and a sealing plate are provided on one side of the gate. The sealing gasket and the sealing plate form a double sealing structure to seal one side of the gate body, preventing water from seeping into the gate beam grid, fundamentally reducing the risk of icing, and improving the overall waterproof performance of the gate, thus solving the problem of easy icing of the beam grid on one side of the gate body.

[0016] The gate body is equipped with spring-supported sealing strips on both sides. The sealing strips achieve dynamic sealing compensation under the action of the supporting springs. Even if there is slight displacement or wear of the gate, it can still fit tightly with the sliding groove of the building, effectively preventing water leakage.

[0017] After the heater is connected to an external power source via a plug, the current is transmitted to the heating wire through the power line. The bent heating wire heats up and transfers heat to the entire beam grid, achieving uniform heating of the beam grid. This effectively prevents water accumulation and ice formation around the gate body, avoiding damage to the gate structure and increased opening and closing resistance caused by ice. Combined with anti-icing coating, which reduces the adhesion strength between ice and the surface, it further assists in preventing icing and ensures smooth opening and closing of the gate. In addition, a clamping cap is installed to fix the plug with bolts, preventing vibration from causing poor contact of the plug and ensuring continuous and stable heating of the gate structure.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Example 1: Please refer to Figures 1 to 9 :

[0038] This utility model proposes an anti-freezing gate device, comprising: a building 1, a supporting frame 2 installed on the top of the building 1, the building 1 and the supporting frame 2 being stably connected according to existing technology, the supporting frame 2 having a U-shaped structure, a stabilizing sleeve provided in the middle of the supporting frame 2, a set of drive mechanisms 6 installed on the inner side of the stabilizing sleeve, a vertical lifting rod 302 inserted between the stabilizing sleeve and the drive mechanisms 6, and a sliding groove provided on each side of the gate body 301, the sliding groove having a rectangular structure, a sealing strip 303 installed inside the sliding groove, and the sealing strip 303 and the sliding groove being connected. Corresponding to the moving groove, a set of symmetrically distributed positioning rods 304 are provided on one side of the sealing strip 303. Two sets of symmetrically distributed positioning sleeves are provided on the inner side of the gate body 301. The positioning rods 304 pass through the interior of the positioning sleeves, and a support spring is installed on the outer side of each positioning rod 304. The support springs elastically support the sealing strip 303 outward, enabling the sealing strip 303 to automatically compensate for the sealing position. Specifically, the elastic force of the support springs ensures that the sealing strip 303 is always in close contact with the sliding groove of the structure 1, achieving dynamic sealing compensation. Even if there is slight displacement or wear in the gate body 301, the sealing performance can still be guaranteed. To prevent water leakage and impurities from entering the sliding groove, a sealing washer 305 is installed on one side of the gate body 301, and a sealing plate 306 is installed on one side of the sealing washer 305. A set of bolt mounting holes is made at the corners of the gate body 301, the sealing washer 305, and the sealing plate 306. The gate body 301, the lifting rod 302, the sealing strip 303, the positioning rod 304, the sealing washer 305, and the sealing plate 306 cooperate to form the gate structure 3. Matching bolts are installed at the bolt mounting holes. After the bolts are installed, the gate body 301, the sealing washer 305, and the sealing plate 306 are stabilized. The fixed assembly, with sealing gasket 305 and sealing plate 306 working together to seal one side of the gate body 301, solves the problem of easy icing on the beam grid on one side of the gate body 301. A positioning groove is opened on one side of the gate body 301 and sealing plate 306 respectively, and the two sides of the sealing gasket 305 extend into the interior of the positioning groove. Specifically, the sealing gasket 305 is embedded in the positioning groove to achieve double sealing. Combined with the pressing action of sealing plate 306, it enhances the sealing performance on one side of the gate body 301, preventing water from seeping into the beam grid and causing icing. At the same time, the sealing structure can reduce the direct contact of cold air with the beam grid, and help reduce the probability of icing.

[0039] In this embodiment, two symmetrically distributed stabilizing grooves are provided above the gate body 301. The stabilizing grooves are rectangular in structure, and a rack 401 is installed on the inner side of each stabilizing groove. The rack 401 has a serrated structure, thus providing directional limiting effect. An elastic frame 402 is installed between the two racks 401. Each side of the elastic frame 402 has a set of locking teeth that engage with the racks 401. An anti-loosening ring 403 is provided on one side of the elastic frame 402. The racks 401, elastic frame 402, and anti-loosening ring 403 cooperate to form an anti-loosening structure 4. The racks 401 and elastic frame 402 cooperate to lock the position of the anti-loosening ring 403. The advantage of the elastic frame 402 is that it can be manually pressed. The deformation, specifically, achieves lateral limiting through the engagement of the rack 401 and the elastic frame 402, preventing the anti-loosening ring 403 from loosening. The deformable characteristics of the elastic frame 402 facilitate installation and disassembly, while ensuring the reliability of the locked state. A locking nut is installed on one side of the connecting bolts of the gate body 301 and the lifting rod 302. One side of the connecting bolt extends into the interior of the anti-loosening ring 403, and the side of the anti-loosening ring 403 contacts the locking nut. Specifically, the tight contact between the anti-loosening ring 403 and the locking nut, through the limiting effect of the anti-loosening structure 4, prevents the connecting bolts from loosening, avoids bolt detachment caused by the vibration generated by the frequent lifting and lowering of the gate body 301, and ensures the connection stability of the gate structure 3.

[0040] In this embodiment, a gate body 301 is bolted to the bottom of the lifting rod 302. A beam grid is provided on the inner side of the gate body 301, and a set of vertical sliding grooves is opened on the inner side of the building 1. The two sides of the gate body 301 extend into the interior of the sliding grooves. Specifically, the sliding grooves provide guidance for the lifting and lowering of the gate body 301, ensuring the stability of its lifting and lowering process, avoiding sealing failure or jamming caused by deviation, and limiting the lateral displacement of the gate body 301, thereby enhancing the overall firmness of the connection between the gate body 301 and the building 1.

[0041] In this embodiment, a heater 501 is installed on the inner side of the beam grid, and the length of the heater 501 corresponds to the inner side of the beam grid. Two heating wires 502 are provided on the outer side of the heater 501. The heating wires 502 have a bent structure. A set of positioning grooves with different positions are opened in the beam grid of the gate body 301. The positioning grooves have a U-shaped structure. The heating wires 502 pass through the inside of the positioning grooves. The heater 501 is energized, so that the heating wires 502 heat the beam grid. Specifically, the bent structure of the heating wires 502 increases the contact area with the beam grid. Combined with the fixing effect of the positioning grooves, it can achieve uniform heating of the beam grid, effectively preventing water accumulation and freezing around the gate body 301, avoiding damage to the gate body 301 structure by ice and increasing the opening and closing resistance. A power cord is provided above the heater 501. A power connector is provided on one side of the power cord. A plug 503 is installed on one side of the power connector. After the plug 503 is installed, it can connect to the heater 501. The plug 503 is used for external power supply and controller connection. A clamping cap 504 is installed on the outside of the plug 503. A pressing ring is provided on the outer side of the plug 503. A bolt mounting hole is opened on each side of the clamping cap 504. The heater 501, heating wire 502, plug 503, and clamping cap 504 cooperate to form the heating structure 5. The bolt mounting holes are installed with matching bolts according to actual needs. The clamping cap 504, together with the bolts, can clamp and position the plug 503, so that the plug 503 is stably electrically connected to the heater 501. The heater 501 is selected according to actual needs. Its specific function is to achieve a stable connection of the plug 503 by fixing it with bolts of the clamping cap 504, preventing poor power contact or plug 503 falling off due to vibration, ensuring stable power supply to the heater 501, facilitating precise control of heating temperature and time through external controller, and improving the reliability of the heating structure 5.

[0042] Example 2, based on Example 1, such as Figures 1-6 As shown, the lifting rod 302 adopts the existing threaded rod structure. The thread pitch is processed according to actual needs. A threaded sleeve is set on the inner side of the drive mechanism 6 to connect the outdoor lifting rod 302. The lifting rod 302 drives the gate body 301 to rise and fall by operating the drive mechanism 6.

[0043] Example 3, based on Example 1, such as Figures 1-6 As shown, anti-freezing coatings are applied to the outer surfaces of the gate body 301 and the sealing plate 306 respectively. The anti-freezing coatings applied to the gate body 301 and the sealing plate 306 reduce the adhesion strength of ice and ensure that the gate body 301 and the sealing plate 306 can be opened and closed normally.

[0044] The working principle of this embodiment:

[0045] Install the support frame 2 at the preset position of the building 1 to make the support frame 2 securely connected to the building 1. Install the drive mechanism 6 inside the stabilizing sleeve of the support frame 2. Then, insert the lifting rod 302 between the stabilizing sleeve and the drive mechanism 6. Install the gate body 301 at the bottom of the lifting rod 302 with bolts so that the two sides of the gate body 301 extend into the vertical sliding groove of the building 1. At the same time, install the locking nut on the side of the connecting bolt between the gate body 301 and the lifting rod 302. Install the rack 401 in the stabilizing groove of the gate body 301. Place the elastic frame 402 between the two racks 401 so that the teeth of the elastic frame 402 mesh with the racks 401 to complete the assembly of the anti-loosening structure 4. Insert one end of the bolt into the anti-loosening ring 403 so that the side of the anti-loosening ring 403 is in close contact with the locking nut.

[0046] A heater 501 is installed inside the beam grid of the gate body 301. A heating wire 502 is passed through the U-shaped positioning groove of the beam grid to ensure that the bent structure of the heating wire 502 is in full contact with the beam grid. Then the power cord of the heater 501 is connected, the plug 503 is installed and fixed by the clamping cap 504 and bolts to make the plug 503 stably electrically connected to the heater 501.

[0047] A sealing strip 303 is installed in the sliding groove on both sides of the gate body 301. The positioning rod 304 is passed through the positioning sleeve of the gate body 301. A support spring is fitted on the outside of the positioning rod 304 so that the spring pushes the sealing strip 303 to fit tightly with the sliding groove.

[0048] A sealing washer 305 and a sealing plate 306 are installed sequentially on one side of the gate body 301 and fixed by bolts passing through the bolt mounting holes of the three, ensuring that the sealing washer 305 is embedded in the positioning grooves of the gate body 301 and the sealing plate 306 on both sides.

[0049] Replace the lifting rod 302 with a threaded rod, set a matching threaded sleeve inside the drive mechanism 6 to make the two threadedly connected, and apply anti-freezing coating to the outer surfaces of the gate body 301 and the sealing plate 306.

[0050] The lifting rod 302 is controlled to move vertically by the drive mechanism 6, which drives the gate body 301 to rise and fall along the sliding groove of the building 1, thereby realizing the opening and closing operation of the gate structure 3.

[0051] When cleaning the gate structure 3 in cold weather, connect the plug 503 to the external power supply and controller, start the heater 501, and make the heating wire 502 heat the beam grid of the gate body 301 to prevent water from accumulating and freezing around the gate structure 3.

[0052] When the gate body 301 is raised or lowered, the sealing strip 303 is always in close contact with the sliding groove under the action of the support spring to ensure sealing performance; the anti-loosening structure 4 prevents the connecting bolts from loosening by the engagement of the rack 401 and the elastic frame 402.

[0053] If maintenance or replacement of parts is required, press the elastic frame 402 to deform it and release it from the engagement with the rack 401, then the anti-loosening structure 4 can be removed; loosen the bolt of the clamping cap 504, and the plug 503 can be removed for maintenance of the heater 501.
