Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing equipment technology, specifically to a hydraulic gate opening and closing device. Background Technology

[0002] Opening and closing devices are mechanical devices used to control the flow of fluid in systems such as pipelines and containers, to shut off or regulate the flow rate. In the application scenario of hydraulic gates, opening and closing devices are key equipment that drive the gate to rise, rotate or move by mechanical or electric means to achieve functions such as water level regulation, water flow control, flood control and drainage or navigation in water areas such as rivers, reservoirs and water conservancy projects.

[0003] A search revealed a Chinese patent (CN222332634U) that includes an outer frame with grooves on both inner walls; a gate that slides into the grooves of the outer frame at both ends; and two sets of protective components symmetrically arranged at both ends of the rear surface of the gate. Each protective component consists of a separator and an adjusting component. The separator includes a first drive wheel and a second drive wheel that pass through the upper and lower ends of one end of the gate, respectively. The first drive wheel and the second drive wheel roll against the two side walls of the groove on the outer frame. The designed protective components can elastically limit the distance between the gate and the outer frame, ensuring that they do not contact each other under normal conditions. Even when there are impurities obstructing the view inside the outer frame, the gate and the outer frame can be separated or fitted together, preventing excessive pressure from impurities that could affect normal lifting and lowering operations. Furthermore, the protective components can reduce the friction between the outer frame and the gate while separating the components.

[0004] When used, the aforementioned patent proposes a protective component that can flexibly limit the distance between the gate and the outer frame. Under normal conditions, the two can be kept out of contact. Even if there are impurities blocking the outer frame, the gate and the outer frame can be separated or fitted together to avoid excessive compression by the impurities, which would affect the normal lifting and lowering operation. However, the aforementioned patent does not fully consider setting an emergency opening and closing function to prevent the gate from being unable to open or close due to a failure of the opening and closing mechanism. Its hydraulic gate opening and closing mode is simple, and the gate is prone to difficulties in opening and closing due to malfunctions.

[0005] To address this, we propose a hydraulic gate opening and closing device that offers diverse adjustment options, is not limited to a single adjustment mode, and boasts better airtightness and a longer service life. Utility Model Content

As a result, the opening and closing mode of the hydraulic gate is limited, and the gate is prone to difficulties in opening and closing due to malfunction.

[0007] To solve the above-mentioned technical problems, this application provides a hydraulic gate opening and closing device, including a frame, a drive module is provided on the top of the frame, a reinforcing component is provided on the rear side of the frame, and a gate module is slidably connected inside the frame.

[0011] In some embodiments, the reinforcing component includes a reinforcing rib, the front side of which is disposed in the middle of the rear side of the frame, and diagonal bracing plates are provided on both sides of the top of the reinforcing rib. The inner sides of the two diagonal bracing plates are respectively disposed on the two rear sides of the frame, and the outer edges of the diagonal bracing plates are smoothly chamfered.

Positioning strips are slidably connected inside the two positioning grooves, and the two positioning strips are respectively disposed on the inner sides of the frame.

[0013] In some embodiments, a sealing strip is provided inside the positioning groove, and two D-shaped waterproof rubber pads are provided at the bottom of the gate body. Both the D-shaped waterproof rubber pads and the sealing strip can deform according to pressure changes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-3 This utility model provides a technical solution:

[0028] The hydraulic gate opening and closing device includes a frame 1, which serves as the basic load-bearing structure of the device, providing installation support and stability for each component. A drive module 2 is installed at the top, which provides the power required for the gate to open and close, realizing the lifting and lowering of the gate. A reinforcing component 3 is installed at the rear, which enhances the overall structural strength of the frame 1 and prevents the device from deforming under the impact of water flow. A gate module 4 is slidably connected inside, and the gate module 4 controls the opening and closing of the water flow channel by sliding.

[0029] The drive module 2 includes four support rods 21, which support and fix the docking block 22. The bottom of each support rod is set on the top of the frame 1, and the docking block 22 is set on the top. The docking block 22 provides installation space and connection carrier for internal parts. A crank assembly 25 is set on the right side. The crank assembly 25 is used to manually drive the device to deal with power failure and other situations. The internal threaded connection is a lead screw 26. The lead screw 26 converts rotation into linear motion, which drives the gate module 4 to rise and fall. A turntable 24 is set on the top.

[0030] The turntable 24 can assist in rotating the lead screw 26 to improve the convenience of the lifting mechanism. A drive assembly 23 is provided on the left side, which serves as an automatic power source to realize the automatic opening and closing of the gate. Telescopic rods 27 are provided on both sides of the inner side of the frame 1. The telescopic rods 27 can guide and limit the sliding of the gate module 4 to ensure smooth lifting. A threaded hole 28 is provided at the top, which cooperates with the lead screw 26 to realize threaded transmission. The lead screw 26 is internally threaded. A fixing ring 29 is provided at the bottom, which is used to connect the lead screw 26 and the gate module 4 to transmit power.

[0031] The drive assembly 23 includes a protective shell 231, which can isolate external moisture and impurities and protect internal parts. The inner side is located on the right side of the docking block 22. The motor 232 is installed inside, which provides the original power. The drive end is equipped with a reducer 233, which can adjust the output speed and torque to adapt to the gate opening and closing requirements. The rod is installed inside, which is used to transmit power to the lead screw 26, which is located inside the docking block 22.

[0032] The crank assembly 25 includes a rocker arm 251, which serves as the lever arm for manual grooving, facilitating the application of rotational force. The inner end is located inside the left side of the docking block 22, and the outer edge is smoothly chamfered to reduce the risk of bumps during grooving. The outer side is rotatably connected to a handle 252, which is convenient for grooving operators to hold. Multiple anti-slip recesses are provided on the outside to enhance friction during gripping and prevent slippage.

[0033] Example 2

[0034] Please see Figures 4-6 The reinforcing component 3 includes a reinforcing rib 31, which can enhance the structural bearing capacity of the middle part of the rear side of the frame 1. The front side is set in the middle of the rear side of the frame 1, and the top two sides are provided with diagonal bracing plates 32. The diagonal bracing plates 32 can disperse the lateral force borne by the frame 1. The inner sides of the two diagonal bracing plates 32 are respectively set on the two rear sides of the frame 1, and the outer edges are smoothly chamfered to avoid scratches during installation and maintenance.

[0035] The gate module 4 includes a gate body 41, which is the core component for blocking or allowing water flow. It is externally slidably connected to the inner side of the frame 1, and positioning grooves 43 are provided on both sides. The positioning grooves 43 provide suitable sliding space for the positioning strips 42. The positioning strips 42 are slidably connected inside the two positioning grooves 43. The positioning strips 42 can limit the sliding trajectory of the gate body 41. The two positioning strips 42 are respectively set on the inner sides of the frame 1.

[0036] The positioning groove 43 is equipped with a sealing strip 44, which can fill the gap between the positioning groove 43 and the positioning strip 42. The bottom of the gate body 41 is equipped with two D-shaped waterproof rubber pads 45. The D-shaped waterproof rubber pads 45 can enhance the sealing between the bottom of the gate and the contact surface. Both the D-shaped waterproof rubber pads 45 and the sealing strip 44 can deform according to the pressure change, thereby improving the sealing effect under different working conditions.

[0037] The gate body 41 includes a composite material gate 411, which balances structural strength and lightweight requirements. The outer surface is coated with a polyurea coating 412, which can resist external environmental corrosion. The interior is provided with a zinc-aluminum-magnesium alloy plating layer 413, which can enhance the corrosion resistance of the inner structure. The interior is provided with a duplex stainless steel layer 414, which further improves the overall structural strength. The interior is provided with a fiber-reinforced composite material layer 415, which can optimize the gate's impact resistance.

[0038] Based on the above embodiments, the following is the complete working principle of the above embodiments: This hydraulic gate opening and closing device uses frame 1 as the installation base. The drive module 2 provides power to drive the gate module 4 to realize the opening and closing action. The reinforcement component 3 strengthens the stability of the overall structure. When the device is running, the drive module 2 acts as the power core to drive the gate module 4. In the drive module 2, four support rods 21 support the docking block 22 on the top of the frame 1. The docking block 22 provides an installation carrier for the lead screw 26. The bottom of the lead screw 26 is connected to the gate module 4 through the fixing ring 29. The lead screw 26 passes through the threaded hole 28 at the top of the frame 1 and is threadedly engaged with it. The power input can be achieved through the drive component 23 or the crank component 2. 5. Implementation: When the drive assembly 23 is used, the motor 232 inside the protective shell 231 starts, and its drive end drives the reducer 233 to run. The rod inside the reducer 233 transmits power to the lead screw 26 inside the docking block 22. When the crank assembly 25 is used, the operator holds the handle 252 with multiple anti-slip recesses on the outside and rotates the crank 251 with a smooth chamfered outer edge. The inner end of the crank 251 transmits power to the lead screw 26 inside the docking block 22. The lead screw 26 rotates under the action of power, and the thread structure of the threaded hole 28 realizes the up and down movement. At the same time, the telescopic rods 27 on both sides of the inner side of the frame 1 can assist in the guidance to ensure the stable movement of the lead screw 26.

[0039] The lead screw 26 drives the gate module 4 to move through the fixed ring 29. The gate body 41 in the gate module 4 slides along the inner side of the frame 1. The positioning grooves 43 on both sides of the gate body 41 slide with the positioning strips 42 on both sides of the inner side of the frame 1 to achieve precise guidance when the gate body 41 is raised and lowered. The sealing strips 44 inside the positioning grooves 43 and the two D-shaped waterproof rubber pads 45 at the bottom of the gate body 41 can deform according to pressure changes to ensure the sealing during the opening and closing of the gate. The gate body 41 adopts a multi-layer structure design, from the outside to the inside, consisting of layers coated with polyurea coating 412. The gate body 41 is constructed with a composite material gate 411, a zinc-aluminum-magnesium alloy coating 413, a duplex stainless steel layer 414, and a fiber-reinforced composite material layer 415, ensuring that the gate body 41 has good strength and corrosion resistance. During the entire operation of the device, the reinforcement component 3 enhances the overall structural stability. The front side of the reinforcing rib 31 is fixed to the middle of the rear side of the frame 1, and the inner sides of the diagonal bracing plates 32 on both sides of its top are connected to the two rear sides of the frame 1 respectively. The outer edges of the diagonal bracing plates 32 are smoothly chamfered. Through the synergistic effect of the reinforcing rib 31 and the diagonal bracing plates 32, the load on the frame 1 is effectively distributed, and structural deformation is avoided.
