Description

Technical Field

[0001] This utility model relates to a gate device for water conservancy projects. Background Technology

[0002] Due to the large drop in elevation, multiple sluice gates are often installed in the river channels between mountain ranges. When the river is flowing normally, debris such as tree branches and bottles will float on the river. In order to reduce the amount of garbage floating downstream in each section of the river, the gates will be in a semi-closed state to intercept the floating objects.

[0003] The semi-closed state of the sluice gate means that the lower edge of the sluice gate is below the water surface, which allows the sluice gate to block floating objects on the water surface, but does not completely cut off the water flow. Therefore, the water can still flow through the lower edge of the sluice gate. This way of using the sluice gate ensures the flow of water in the river channel while intercepting garbage. The sluice gate manager usually only needs to clean the intercepted garbage once a month.

[0004] However, the aforementioned sluice gates also encountered problems during use. During sudden heavy rains, the water volume in the river increases, and the sluice gates need to be opened immediately to allow the river water to flow out. In such emergency situations, opening the sluice gates becomes the top priority for river management personnel, and there is no extra time to clean up the trapped garbage.

[0005] With multiple sluice gates opened upstream, a large amount of intercepted and uncleaned garbage moves downstream, resulting in a large accumulation of floating garbage in the lower reaches of the river. Utility Model Content

[0006] The purpose of this invention is to provide a gate device for water conservancy projects that reduces the accumulation of floating garbage flowing downwards after the gate is opened.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A gate device for a water conservancy project includes: a gate; a collection basket installed on the water-facing side of the gate; the collection basket is disposed near the lower edge of the gate; when the gate descends and the lower edge is underwater, the collection basket moves down into the water simultaneously.

[0008] Preferably, the collection basket has an overall elongated shape, with the lower edge of the collection basket parallel to the lower edge of the gate.

[0009] Preferably, a rotating shaft is fixed on one side of the gate and a stop bar is fixed on the other side; one end of the collection basket is rotatably connected to the rotating shaft, and the other end of the collection basket abuts against the top of the stop bar.

[0010] Preferably, the collection basket is made of stainless steel.

[0011] Preferably, a pressure plate is fixed to one end of the collection basket, and the pressure plate presses against the stop bar.

[0012] Preferably, it includes a concrete base and a frame fixed on the base; the gate slides vertically on the frame, and the water-facing side of the gate and the water-facing side of the frame are flush; a drive unit for moving the gate is installed at the upper end of the frame.

[0013] Preferably, a pull rope is fixed to one end of the collection basket near the stop bar; the frame includes a crossbar, a deflector is fixed on the crossbar, the pull rope passes around the deflector and is fixed to the frame at the other end; when the gate is raised, the user pulls the pull rope on the frame to flip the collection basket over and dump the garbage toward the riverbank.

[0014] In summary, this utility model has at least one of the following beneficial effects: A collection basket that moves up and down synchronously with the gate is used. When the gate is half closed, the collection basket is below the water surface. When the gate moves up suddenly, the collection basket moves up synchronously to collect the garbage blocked by the gate into the basket. This prevents a large amount of intercepted garbage from flowing downwards when the gate is opened suddenly, and reduces the accumulation of floating garbage flowing downwards.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example 1: A gate device for a water conservancy project, referring to... Figures 1-3 It includes a concrete base 3, which is fixed to both sides of the river channel by concrete pouring.

[0019] A frame 4 is installed on the concrete base 3. The frame 4 is a rectangular metal frame and is fixed to the concrete base 3 by screws 23 and cement.

[0020] The frame 4 has a sliding gate 1 inside. The inner side of the frame 4 is provided with a vertical track 43. Sliding blocks 13 are fixed on both sides of the gate 1. The sliding blocks 13 slide on the track 43. A drive unit 5 for moving the gate 1 is installed on the upper end of the frame 4. Above the frame 4 is a crossbar 41. The drive unit 5 includes a threaded valve stem and a rotating wheel. The threaded valve stem is installed on the crossbar 41, and the lower end of the threaded valve stem is connected to the gate 1. Rotating the rotating wheel can realize the raising and lowering of the gate 1. The raising and lowering drive unit 5 of the gate 1 is a conventional technical means in this field, and will not be described in detail in this application.

[0021] The side of the gate that impacts the water flow is the water-facing side of the gate.

[0022] The water-facing side of gate 1 and the water-facing side of frame 4 are flush; The gate 1 is equipped with a collection basket 2, which is a long strip structure, and the lower edge of the collection basket 2 is parallel to the lower edge of the gate 1.

[0023] Collection basket 2 is made of stainless steel and is not prone to rusting in water.

[0024] The sides and bottom of the collection basket 2 are provided with drainage holes to drain water, but their size is designed to prevent beverage bottles from leaking out. For example, the width of the drainage hole is set to 3cm.

[0025] The collection basket 2 is welded and fixed at both ends with support rods, and fastening screws 23 are installed on the support rods. The caps of the fastening screws 23 press against the support rods, and the threaded parts of the fastening screws 23 are connected to the gate 1, thereby fixing the collection basket 2 to the gate 1.

[0026] The working principle is as follows: When the gate 1 is partially closed, the collection basket 2 is located in the underwater area on the water-facing side of the gate 1. Floating garbage is blocked on the water-facing side by the gate 1. When the gate 1 is raised, it catches the garbage that was originally floating on the water surface.

[0027] When the user urgently raises gate 1, a large amount of garbage falls into the collection basket 2 from bottom to top. As the collection basket 2 rises, the garbage is removed from the river surface. When the user is free, they can use tools to collect the garbage in the collection basket 2 and remove it. This prevents the large amount of garbage trapped when gate 1 is opened in an emergency from flowing downwards.

[0028] During normal operation, the collection basket 2 is located below the water surface, and users can periodically use tools to collect the garbage intercepted by the gate 1.

[0029] Example 2, a gate device for a water conservancy project, differs from Example 1 in that, referring to... Figures 4-7 For the water-facing side of gate 1, a rotating shaft 11 is welded and fixed on one side of gate 1, and a stop bar 12 is welded and fixed on the other side of gate 1.

[0030] A bushing 22 is welded to one end of the support rod of the collection basket 2. The bushing 22 is fitted onto the rotating shaft 11, so that the collection basket 2 can rotate vertically around the rotating shaft 11.

[0031] The other end of the collection basket 2 is welded with a pressure plate 21. The pressure plate 21 has an arc-shaped notch, which can be embedded into the upper part of the baffle 12.

[0032] With the vertical support of the stop bar 12 and the rotating shaft 11, the collection basket 2 can be stably installed on the gate 1; In other embodiments, a counterweight can be welded into the collection basket 2 to make the collection basket 2 more stable underwater.

[0033] Working principle: After the collection basket 2 collects the garbage and rises, the user can use tools such as hooks to pull the collection basket 2, causing it to rotate towards the shore, thereby dumping the garbage onto the shore, making it easier to clean the garbage in the collection basket 2.

[0034] Example 3, a gate device for a water conservancy project, differs from Example 2 in that, referring to... Figures 8-10 A pull rope 6 is fixed to one end of the collection basket 2 near the stop bar 12; the pull rope 6 and the collection basket 2 are tied together.

[0035] A steering gear 42 is welded and fixed to the crossbar 41. The steering gear 42 is an L-shaped rod.

[0036] A fixing rod 61 is fixed on the frame 4, and the fixing rod 61 is arranged near the rotating shaft 11; One end of the pull rope 6 is fixed to the collection basket 2. The pull rope 6 passes around the deflector 42 to achieve deflection, and the other end is tied to the fixed rod 61 of the frame 4.

[0037] Working principle: After the gate 1 is moved to the half-closed state, the pull rope 6 is wound around the fixed rod 61; When the gate 1 rises, first release the pull rope 6. The pull rope 6 is still inside the diverter 42. After the user unties the pull rope 6 on the fixing rod 61, pull it forcefully. Since one end of the pull rope 6 is fixed to the side of the collection basket 2 away from the rotating shaft 11, pulling the pull rope 6 after untying it can change the direction of force through the diverter 42, driving the collection basket 2 to flip around the rotating shaft 11. The collection basket 2 is flipped by the force of the pull rope 6 and dumps garbage onto the riverbank under the action of inertia.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
