Description

Technical Field

[0001] This utility model relates to the technical field of anti-tangling front nets for hydroelectric generators, and particularly to anti-tangling front nets for hydroelectric generators. Background Technology

[0002] During hydropower generation, the water flow often contains suspended matter such as resin, plastic bags, and aquatic plants due to the external environment. If these suspended matter are not intercepted and removed, they can easily enter the turbine of the hydropower generator with the water flow and cause entanglement, which will greatly reduce the efficiency of the hydropower generator. Therefore, a corresponding anti-entanglement front net is often installed at the water inlet of the hydropower equipment to intercept the suspended matter in the water flow.

[0003] Common anti-winding pre-filters for hydroelectric generators are mostly installed at the water inlet to isolate suspended solids in the water flow. They are then cleaned periodically to prevent these solids from entangled in the generator's turbine. While these common anti-winding pre-filters for hydroelectric generators have a good effect on intercepting suspended solids, some problems still exist:

[0004] When using common anti-entanglement front nets for hydroelectric generators, a large amount of suspended matter will become entangled on the surface of the net after a long period of use. It is often necessary to remove and clean them regularly before they can be reused. However, it is often inconvenient to remove common front nets. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-tangling front net for hydroelectric generators, in order to solve the problem of inconvenient disassembly and assembly of existing anti-tangling front nets for hydroelectric generators.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-winding front net for a hydroelectric generator, comprising a main frame and a top frame. Reinforcing structures are fixedly connected to the middle positions on both sides of the main frame. A control panel is fixedly connected to one end of one side of the main frame. A top frame is fixedly connected to the top of the main frame. Lifting frames are slidably connected to both ends inside the main frame. A traction winding assembly is fixedly connected to the top of the top frame. A guide wheel is fixedly connected to the inner side of the top frame. A collecting structure is fixedly connected to the bottom of one end of the lifting frame. A disassembly and assembly structure is installed inside the lifting frame. The disassembly and assembly structure includes an intercepting net, a slot, a guide rod, a return spring, a baffle, and a plug. The intercepting net is embedded inside the lifting frame.

[0007] In use, the pre-net is submerged at the inlet of the hydroelectric generator and secured with the side frame. At this point, most of the net is submerged at the inlet, allowing suspended debris in the water flow to be intercepted. The control panel controls the traction and winding assembly to slide the two sets of lifting frames up and down along the inner side of the main frame via traction ropes. During use, one set of nets intercepts suspended debris. After one set of nets has been used for a long time, the other set can be lowered, and the net that needs to be cleaned can be pulled up for subsequent cleaning and reuse.

[0008] Preferably, the reinforcing structure includes a side frame, an internal threaded sleeve, a rotating head, and a threaded rod. The side frame is fixedly connected to the middle position on both sides of the main frame. An internal threaded sleeve is fixedly connected to the bottom end of the inner side of the side frame. A rotating head is provided above the internal threaded sleeve. A threaded rod is fixedly connected to the bottom end of the rotating head.

[0009] Preferably, the internal threaded sleeves are symmetrically distributed at the bottom of the inner side of the side frame, and the internal threaded sleeves and the threaded rods are connected by a thread, thereby making the installation of the front net more stable.

[0010] Preferably, the collection structure includes a collection frame, a flip plate, filter holes, a stop block, a rotating shaft, and a torsion spring. The collection frame is fixedly connected to the bottom of one end of the lifting frame. A flip plate is rotatably connected to one end of the inner side of the collection frame. Filter holes are provided inside the flip plate. A stop block is fixedly connected to the inner side of the collection frame. Rotating shafts are fixedly connected to both sides of the flip plate. A torsion spring is sleeved on the outer side of the rotating shaft.

[0011] Preferably, the filter holes are evenly spaced inside the flip plate, and the collection frame and the rotating shaft are in a rotating structure, so that the flip plate can close automatically.

[0012] Preferably, slots are provided on both sides of the inside of one end of the interception net, guide rods are fixedly connected to both sides of one end of the lifting frame, a return spring is sleeved on one end of the outer side of the guide rod, a baffle is slidably connected to the other end of the outer side of the guide rod, and a plug is fixedly connected to one side of one end of the baffle.

[0013] Preferably, the slot and the plug are in an inlay structure, and the guide rods are symmetrically distributed about the vertical center line of the lifting frame, so as to make the installation of the interception net more stable and convenient.

[0014] Compared with the existing technology, the beneficial effects of this utility model are: by rotating the rotating head, the threaded rod is deeply inserted into the soil near the water inlet, thereby making the device securely installed. At the same time, after the lifting frame rises, most of the suspended matter intercepted by the interception net can fall into the inside of the collection frame for collection and cleaning. Furthermore, the installation and removal of the interception net are made more convenient by the rotation and locking of several baffles and inserts.

[0015] 1. The insertion block can be inserted into the slot for embedding by the elastic force of the return spring and the rotation and sliding of the baffle. The sliding baffle makes the installation and removal of the interception net more convenient.

[0016] 2. Side frames are fixed on both sides of the main frame, and the threaded rod is inserted into the soil near the inlet by rotating the rotating head along the inner thread of the inner thread sleeve, so as to make the installation of the pre-screen net more stable.

[0017] 3. When the water flows, the tilting plate gradually tilts due to the water flow. When the lifting frame is raised, the tilting plate closes quickly under the elastic torque of the torsion spring and the action of the stop block, so that most of the suspended objects intercepted by the interception net fall into the inside of the collection frame and are picked up.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figures 1-6 The anti-winding front net for a hydroelectric generator provided by this utility model includes a main frame 1 and a top frame 4. A control panel 3 is fixedly connected to one end of one side of the main frame 1, and the top frame 4 is fixedly connected to the top of the main frame 1. Lifting frames 7 are slidably connected to both ends inside the main frame 1. A traction winding assembly 5 is fixedly connected to the top of the top frame 4, and a guide wheel 6 is fixedly connected to the inner side of the top frame 4. Reinforcing structures 2 are fixedly connected to the middle positions on both sides of the main frame 1. The reinforcing structures 2 include side frames. 201, internal threaded sleeve 202, rotating head 203 and threaded rod 204. The side frame 201 is fixedly connected to the middle position of both sides of the main frame 1. The internal threaded sleeve 202 is fixedly connected to the bottom of the inner side of the side frame 201. The rotating head 203 is set above the internal threaded sleeve 202. The bottom of the rotating head 203 is fixedly connected to the threaded rod 204. The internal threaded sleeve 202 is symmetrically distributed at the bottom of the inner side of the side frame 201. The internal threaded sleeve 202 and the threaded rod 204 are threadedly connected.

[0027] See attached document Figure 1 and Figure 3 When the pre-filter is in use, its bottom is submerged at the water inlet of the hydroelectric generator so that the intercepting net 901 can intercept suspended objects in the water flow. When there are large suspended objects in the water flow and the water flow speed is fast, the suspended objects will cause a large impact on the pre-filter. In order to avoid the pre-filter shifting or collapsing due to the impact of suspended objects, side frames 201 are fixed on both sides of the main frame 1. By rotating the rotating head 203, the threaded rod 204 is inserted into the soil near the water inlet along the internal thread of the inner thread sleeve 202, so as to make the installation of the pre-filter more stable.

[0028] A collection structure 8 is fixedly connected to the bottom of one end of the lifting frame 7. The collection structure 8 includes a collection frame 801, a flip plate 802, filter holes 803, a stop block 804, a rotating shaft 805, and a torsion spring 806. The collection frame 801 is fixedly connected to the bottom of one end of the lifting frame 7. The flip plate 802 is rotatably connected to one end of the inner side of the collection frame 801. Filter holes 803 are opened inside the flip plate 802. The stop block 804 is fixedly connected to the inner side of the collection frame 801. The rotating shaft 805 is fixedly connected to both sides of the flip plate 802. The torsion spring 806 is sleeved on the outer side of the rotating shaft 805. The filter holes 803 are evenly distributed inside the flip plate 802. The collection frame 801 and the rotating shaft 805 are in a rotating structure.

[0029] See attached document Figure 1 , Figure 2 , Figure 4 and Figure 5 When the front net is in use, the traction winding assembly 5 winds up the traction rope, causing the two sets of lifting frames 7 to lift and lower the interception net 901. This allows the two sets of interception nets 901 to be used and cleaned alternately when there is a lot of suspended matter entangled. In order to remove the suspended matter and avoid clogging the water inlet, a collection frame 801 is fixed at the bottom of the front end of the lifting frame 7. When the water flows, the flip plate 802 gradually flips due to the water flow. When the lifting frame 7 rises, the flip plate 802 closes quickly under the elastic torque of the torsion spring 806 and the action of the stop block 804, and the clean water is discharged through the filter hole 803. At this time, most of the suspended matter intercepted by the interception net 901 falls into the inside of the collection frame 801, so that most of the suspended matter can be removed when the lifting frame 7 rises.

[0030] The inner side of the lifting frame 7 is equipped with a disassembly and assembly structure 9, which includes an interception net 901, a slot 902, a guide rod 903, a return spring 904, a baffle 905, and a plug 906. The interception net 901 is embedded in the inner side of the lifting frame 7. Slots 902 are provided on both sides of the inner side of one end of the interception net 901. Guide rods 903 are fixedly connected to both sides of one end of the lifting frame 7. A return spring 904 is sleeved on one side of the outer side of the guide rod 903. A baffle 905 is slidably connected to the other side of the outer side of the guide rod 903. A plug 906 is fixedly connected to one side of one end of the baffle 905. The slots 902 and the plug 906 are embedded in each other. The guide rods 903 are symmetrically distributed about the vertical center line of the lifting frame 7.

[0031] See attached document Figure 2 and Figure 6When the front net is used for a long time, the intercepting net 901 is easily blocked by suspended objects, which reduces the water flow velocity at the water inlet of the hydroelectric generator and thus reduces the power generation efficiency of the hydroelectric generator. Therefore, the intercepting net 901 needs to be removed and cleaned regularly. For this purpose, a corresponding groove is opened inside the front end of the lifting frame 7 so that the intercepting net 901 can be embedded inside the front end of the lifting frame 7. Through the elastic force of the return spring 904 and the rotation and sliding of the baffle 905, the insert 906 can be inserted into the slot 902 for embedding. The sliding baffle 905 makes the installation and removal of the intercepting net 901 more convenient.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
