Description

Technical Field

[0001] This utility model relates to the field of screw gate hoist technology, and in particular to a simple water inlet valve for blocking mud and sand debris. Background Technology

[0002] Screw gate hoists are a type of mechanical equipment widely used in water conservancy projects. Their core function is to convert the rotational motion of the screw into the vertical lifting motion of the gate through human or electric drive, thereby realizing the opening, closing or flow regulation of water flow. They are mainly composed of components such as base, screw, nut, load-bearing nut, gearbox (or handwheel), etc., and their working principle is similar to a huge jack.

[0003] The opening and closing of a river channel can be achieved through a valve plate inside the gate hoist. For example, Chinese Patent Publication No. CN222862204U discloses a gate hoist, including an outer frame and a gate plate. A rod connector is fixedly installed at the upper end of the gate plate, and upper hooks are fixedly installed on both sides of the rod connector. A gate is fixedly installed below the gate plate on the outer frame, and an upper fastener is fixedly installed at the upper end of the gate. Two lower hooks are fixedly installed at the bottom end of the gate plate, corresponding to the bottom end of the gate plate. L-shaped fasteners are rotatably installed on the lower hooks. When the gate plate slides down the track of the outer frame and moves radially, the upper hooks follow and hook onto the upper fasteners at the top of the gate, ensuring that the upper end of the gate plate does not shift. When the gate plate slides to the bottom, its bottom end abuts against one end of the L-shaped fastener on the lower hook, causing the upper end of the L-shaped fastener to engage with the reinforcing rib on the gate plate, thus ensuring that the top and bottom ends of the gate plate are on the same vertical plane, greatly improving the sealing performance of the sealing strip.

[0004] In practice, after the river channel is closed, the silt and impurities in the water flow settle at the bottom of the river. If a gate is set up in the frame, when the gate rises to connect the river channel, the silt and impurities settled at the bottom of the river channel will flow out with the water flow. It cannot block the settled silt and impurities at the same time as connecting the river channel, so it is not very practical. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot block sediment and impurities while connecting waterways, and to propose a simple inlet valve for blocking sediment and impurities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a simple water inlet valve to block mud and sand debris, consisting of two valve plates and a track. The two valve plates are arranged one above the other and slidably connected in the track. A drive mechanism is arranged at the top of the track, and the output end of the drive mechanism is connected to the valve plate placed at the top. A fixing component is provided between the two valve plates, and the fixing component cooperates with the driving mechanism to drive the two valve plates to rise and fall synchronously; The fixing component includes a fixing base and a rod, and the rod is detachably connected to the fixing base through a positioning structure.

[0007] Furthermore, the fixing assembly also includes fixing plates, with a plurality of fixing plates fixedly connected to the end sidewall of one of the valve plates, the free end of the fixing plate extending to the end sidewall of another valve plate and also fixedly connected to the fixing seat.

[0008] Furthermore, the fixed base has a stepped groove inside and a first wedge-shaped part on the outer wall of the end. The first wedge-shaped part and the stepped groove are slidably connected at the axis to the rod. One end of the rod has a second wedge-shaped part. The second wedge portion and the first wedge portion avoid each other through the wedge-shaped surface and abut against each other through the planar end.

[0009] Furthermore, the first wedge-shaped portion has a positioning part at its planar end, and the second wedge-shaped portion has a positioning hole at its planar end, with the positioning part being movably inserted into the positioning hole.

[0010] Furthermore, the positioning structure is a ball-headed plunger, the free end of the rod is fitted with the ball-headed plunger, and a fixing pin is fixedly connected to the periphery of its free end through the ball-headed plunger. The fixing pin is movably inserted into the pin hole of the valve plate side wall.

[0011] Furthermore, a compression spring is also sleeved around the periphery of the rod between the fixing pin and the inner wall of the stepped groove.

[0012] The present invention proposes a simple water inlet valve for blocking silt and debris. The advantages are as follows: In this invention, two valve plates are slidably connected inside the track. One valve plate is initially fixed to the bottom of the track by a drive mechanism. The two valve plates work together to block the silt and debris that settle inside the blocked river channel and to block the river channel. The other valve plate is connected to the drive mechanism and is initially set at the normal water level of the river channel. The drive mechanism can drive the valve plate to rise and fall, thereby realizing the function of connecting and blocking the river channel. Furthermore, because of the bottom valve plate, the silt and debris that settle at the bottom can be blocked to the greatest extent when connecting the river channel. The two valve plates are connected by a fixed component and can be raised and lowered synchronously. This allows the silt and impurities accumulated at the bottom of the track to be cleared by driving the two valve plates to rise, thus preventing the river channel from becoming blocked over a long period of time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A simple water inlet valve for blocking mud and sand debris consists of two valve plates 1 and a track 2. The two valve plates 1 are arranged one above the other and are slidably connected in the track 2. A drive mechanism 3 is provided at the top of the track 2, and the output end of the drive mechanism 3 is connected to the valve plate 1 placed at the top. A fixing component 4 is provided between the two valve plates 1, and the fixing component 4 cooperates with the driving mechanism 3 to drive the two valve plates 1 to rise and fall synchronously. The fixing component 4 includes a fixing base 41 and a rod 42, and the rod 42 is detachably connected to the fixing base 41 through a positioning structure 5.

[0017] Reference Figure 1 As shown, two valve plates 1 are set up one above the other and are respectively a water blocking valve plate and a mud blocking valve plate. The mud blocking valve plate is initially fixed to the bottom of the track (i.e. the bottom of the river channel) by a drive mechanism to block the sediment and impurities that settle inside the blocked river channel. The water-blocking valve plate is connected to the drive mechanism and is initially set at the normal water level of the river. The drive mechanism can drive the valve plate to rise and fall, thereby achieving the function of connecting and blocking the river. Furthermore, because of the setting of the sediment-blocking valve plate, the sediment-blocking impurities at the bottom can be blocked to the greatest extent when connecting the river. The two valve plates 1 are connected by a fixing component 4 to lift and lower synchronously. This allows the mud and impurities accumulated at the bottom of the track 2 to be cleared by driving the two valve plates 1 to rise, thus preventing the river channel from becoming blocked over a long period of time.

[0018] It should be noted that the inlet valve in this application can be referenced from the screw gate opener in the prior art. Therefore, the specific operation mode and working principle of the valve and the drive mechanism 3 will not be described in detail here.

[0019] Furthermore, the fixing component 4 also includes a fixing plate 43, a plurality of fixing plates 43 are fixedly connected to the end side wall of one of the valve plates 1, the free end of the fixing plate 43 extends to the end side wall of another valve plate 1 and is also fixedly connected to the fixing seat 41.

[0020] Furthermore, the fixed base 41 has a stepped groove 44 inside and a first wedge-shaped portion 45 on the outer wall of the end. The first wedge-shaped portion 45 and the stepped groove 44 are slidably connected at the axis to the rod 42. One end of the rod 42 has a second wedge-shaped portion 46. The second wedge-shaped portion 46 and the first wedge-shaped portion 45 avoid each other through the wedge-shaped surface and abut against each other through the planar ends.

[0021] More specifically, the first wedge-shaped portion 45 has a positioning portion 451 at its planar end, and the second wedge-shaped portion 46 has a positioning hole 461 at its planar end, with the positioning portion 451 being movably inserted into the positioning hole 461.

[0022] In this embodiment, as Figure 3 As shown, under normal circumstances, the fixing pin 47 moves toward one end of the pin hole 48 under the guidance of the rod 42 and the elastic support of the compression spring 49. The upper and lower valve plates 1 are connected and fixed by the fixing pin 47 being movably inserted into the pin hole 48. After fixing, the two valve plates 1 can be driven to rise and fall as a whole by the drive mechanism 3. Specifically, such as Figure 4 As shown, a handwheel is fixedly connected to the free end of the rod 42. The rod 42 is driven to move by the handwheel, and the fixing pin 47 moves synchronously during the movement, and the first wedge portion 45 and the second wedge portion 46 separate. Then, the rod 42 is rotated half a circle so that the flat ends of the first wedge portion 45 and the second wedge portion 46 correspond to each other. More specifically, when the rod 42 is reset by the compression spring 49, the flat ends of the first wedge 45 and the second wedge 46 abut against each other, and at the same time, the positioning part 451 is inserted into the positioning hole 461 to prevent the two wedges from rotating and causing the fixing pin 47 to reset. After the two wedge-shaped parts stop, the fixing pin 47 disengages from the pin hole 48 and retracts into the fixing seat 41, thereby disconnecting the connection between the two valve plates 1.

[0023] In general, the positioning structure 5 is a ball-head plug, the free end of the rod 42 is fitted with the ball-head plug, and the periphery of its free end is also fixedly connected to a fixing pin 47 through the ball-head plug. The fixing pin 47 is movably inserted into the pin hole 48 on the side wall of the valve plate 1.

[0024] Finally, a compression spring 49 is also sleeved on the periphery of the rod 42 between the fixing pin 47 and the inner wall of the stepped groove 44.

[0025] In this embodiment, as Figure 5 As shown, the ball-head plunger is an existing technology. Its specific principle is that the plunger slides in the matching hole or groove by a spring. The preload of the spring causes the plunger to be pushed out, so that the end of the plunger can be inserted into the pit, notch or bevel on another component to achieve the positioning function. Specifically, after pressing the ball head plunger to retract it and disengage it from the fixing pin 47, the fixing pin 47 can be disassembled, and the internal components of the entire fixing assembly 4 can be disassembled, replaced, and maintained. More specifically, those in the field will know that valves are installed and used in waterways, so the valve plate 1, track 2, fixing component 4, and positioning structure 5 need to be made of corrosion-resistant materials such as stainless steel. They also know that any component needs maintenance after long-term use, so the pressure spring 49 and positioning structure 5 can be replaced periodically by disassembling the fixing pin 47 to ensure that they can function properly.

[0026] Working method: The drive mechanism 3 drives two valve plates 1 to be set at the bottom of the track 2. The two valve plates 1 cooperate with each other to block the river channel, and the bottom valve plate 1, namely the sediment blocking valve plate, is used to block the sediment that settles inside the blocked river channel. Among them, the drive mechanism 3 drives the top valve plate 1 to rise, which can connect the river channel, and the bottom valve plate 1 can also block silt. The two valve plates 1 can be connected and fixed by the fixing component 4, so the drive mechanism 3 can drive the two valve plates to rise and fall synchronously, thus cleaning the mud and sand impurities accumulated at the bottom of the track 2.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
