Description

Technical Field

[0001] This invention relates to the field of trash rack cleaning technology in hydropower stations, and in particular to a trash rack flushing device and system. Background Technology

[0002] The basic principle of hydroelectric power generation in a hydroelectric power station is to utilize the difference in water level to generate electricity in conjunction with a turbine generator, that is, to convert the potential energy of water into the mechanical energy of the turbine. However, a large amount of floating debris and domestic waste carried downstream by the water flow easily accumulates in front of the hydroelectric power station's intake, causing significant disruption to safe operation and stable generator operation. If not removed promptly, the water level difference between the front and back of the trash rack can reach several meters, which can range from affecting power output to clogging or even damaging the trash rack and hydraulic structures, endangering the normal operation of the hydroelectric power station, or forcing it to shut down for maintenance, resulting in substantial power loss.

[0003] In real-world production environments, both common rake-type and rotary trash rack cleaners have significant drawbacks. Rake-type cleaners, installed at the front of the trash rack, cannot descend deeply due to inlet water pressure, resulting in incomplete cleaning of the trash rack. Rotary trash rack cleaners have stringent installation requirements, and their bottoms are prone to clogging with debris. Clogging necessitates emptying the reservoir for cleaning, leading to power loss. Some hydroelectric power stations only have trash racks installed at their intakes, without any cleaning equipment. Therefore, a trash rack flushing device and system are needed to address these issues. Summary of the Invention

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0034] Example 1

[0035] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a trash rack flushing device, which includes a spray gun assembly 100 and an adjustment assembly 200. The spray gun assembly 100 is used to install the water gun, and the adjustment assembly 200 is used to adaptively adjust the water pressure.

[0036] Specifically, the spray gun assembly 100 includes a base 101, a top column 102 disposed on top of the base 101, and a spray gun housing 103 disposed above the top column 102. The base 101 is installed on a platform downstream of the trash rack of the hydroelectric power station, so that the entire device faces the trash rack. A handle 103a is installed at the end of the spray gun housing 103, which allows the operator to rotate the water gun at multiple angles.

[0037] Preferably, the adjustment assembly 200 includes a nozzle 201 disposed at the end of the spray gun housing 103, a retraction member 202 disposed around the nozzle 201, a transmission member 203 disposed at one end of the retraction member 202, and a trigger member 204 disposed at the end of the transmission member 203. The nozzle 201 is conical, and its rear end is connected to a water inlet pipe. The retraction member 202 covers the outside of the nozzle 201 and can change the orifice size of the nozzle 201. The transmission member 203 and the trigger member 204 are the main components for adaptively changing the orifice size of the nozzle 201.

[0038] When in use, when the operator operates the handle 103a to make the water gun wash the trash rack, the trigger 204 will move accordingly as the water gun is aimed at different positions, and drive the retractor 202 to move through the transmission component 203, thereby causing the orifice diameter of the nozzle 201 to change continuously. That is, when washing a distant part of the trash rack, the nozzle 201 needs to be raised slightly. At this time, the orifice diameter of the nozzle 201 will automatically become smaller, and the water flow will become faster and the impact force will be stronger. The same principle applies to swinging left and right to spray to both sides, thus realizing the change of water pressure without frequent manual changes to the pressure of the booster pump.

[0039] Example 2

[0040] Reference Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the bottom of the top post 102 is cylindrical and fixed to the base 101, while the top of the top post 102 is hemispherical. A first arc-shaped surface 102a is provided at the connection between the hemispherical top and the cylindrical bottom of the top post 102, and second arc-shaped surfaces 102b are provided on both sides of the first arc-shaped surface 102a. The hemispherical top of the top post 102 is embedded in the spray gun housing 103, allowing the spray gun to rotate arbitrarily at multiple angles. The first arc-shaped surface 102a smoothly transitions to the hemispherical surface, and the radial radius of the top post 102 gradually increases from low to high. Meanwhile, the second arc-shaped surface 102b causes the radial radius of the top post 102 to gradually increase or decrease in the horizontal direction.

[0042] Preferably, the shrinkage member 202 includes an arc-shaped plate 202a disposed on the outer surface of the nozzle 201. The arc-shaped plate 202a has a connecting groove 202a-1 inside and a rubber ring 202b inside. The end of the arc-shaped plate 202a also has a connecting hole 202a-2, and a connecting rope 202c is disposed inside. A connecting block 202a-3 is also fixedly disposed on the outer surface of the arc-shaped plate 202a. In this embodiment, six arc-shaped plates 202a are provided, each closely attached to the outer surface of the nozzle 201 and capable of sliding along the conical surface of the nozzle 201. The rubber ring 202b is elastic, causing the six arc-shaped plates 202a to always tend to converge towards the center. Therefore, as the arc-shaped plates 202a gradually slide downwards along the conical surface of the nozzle 201, the six arc-shaped plates 202a will gradually converge towards the center, thus reducing the orifice diameter of the nozzle 201. Upon retraction, the orifice diameter gradually increases again. The extreme position of the six arc-shaped plates 202a is when their tips are completely in contact with each other. The rubber ring 202b also prevents water leakage from the gaps between the arc-shaped plates 202a. The connecting rope 202c, also made of an elastic material, serves to connect the arc-shaped plates 202a.

[0043] Preferably, the transmission component 203 includes a connecting rod 203a slidably connected to the connecting block 202a-3. A movable ring 203b is fixedly connected to the other end of the connecting rod 203a. The movable ring 203b slidably engages with the pipe behind the nozzle 201. A groove 203b-1 is also provided on one side of the movable ring 203b. Pushing the movable ring 203b along the pipe controls the movement of the arc-shaped plate 202a. The connecting block 202a-3 has a movable groove to prevent interference during movement.

[0044] Preferably, the transmission component 203 further includes a first spring 203c disposed on one side of the moving ring 203b. The two ends of the first spring 203c are fixedly connected to the moving ring 203b and the nozzle 201 pipe, respectively. The first spring 203c is a tension spring, mainly used for the reset of the moving ring 203b, that is, the reset of the arc plate 202a.

[0045] The transmission component 203 also includes a roller 203d disposed within the slide groove 203b-1, a swing arm 203e rotatably connected to the roller 203d, and a rotating shaft 203f fixedly connected to the other end of the swing arm 203e. A first-degree wide gear 203f-1 is also disposed at both ends of the rotating shaft 203f. When the rotating shaft 203f rotates, the swing arm 203e swings accordingly. When the swing arm 203e swings towards the moving ring 203b, the roller 203d pushes the moving ring 203b to move. At this time, the arc-shaped plate 202a gradually slides downwards along the conical surface of the nozzle 201, and the orifice diameter of the nozzle 201 decreases. The roller 203d is designed to reduce friction and make the movement smoother.

[0046] Preferably, the trigger 204 includes a longitudinal trigger rod 204a that meshes with a first wide gear 203f-1, and a second spring 204b disposed at the end of the longitudinal trigger rod 204a, the other end of the longitudinal trigger rod 204a engaging with a first arcuate surface 102a. Each of the first wide gear 203f-1 has a longitudinal trigger rod 204a that meshes with it. The longitudinal trigger rod 204a has serrations at the corresponding positions. The two longitudinal trigger rods 204a are joined together in the middle and finally lead to the first arc surface 102a and fit against it. The ends of the longitudinal trigger rods 204a are smooth. When the nozzle 201 is raised, the longitudinal trigger rods 204a will be squeezed and gradually move towards the nozzle 201 because the radial radius of the top column 102 at the first arc surface 102a gradually increases from low to high. This drives the first wide gear 203f-1 to rotate, which in turn drives the swing arm 203e to swing and push the moving ring 203b to move. At this time, the arc plate 202a will gradually slide down along the conical surface of the nozzle 201, and the orifice of the nozzle 201 will become smaller. This achieves the goal that as long as the nozzle 201 is raised, its orifice will become smaller, which meets the need for the water flow to be sprayed to a distance and the water pressure to increase when the nozzle 201 is raised. The second spring 204b is a compression spring, which serves to reset the spray gun, and its other end is fixed inside the spray gun housing 103.

[0047] The trigger 204 also includes a transverse connecting rod 204c, one end of which meshes with the first wide gear 203f-1 and is located on one side of the longitudinal trigger rod 204a. The other end of the transverse connecting rod 204c is also provided with a second wide gear 204d. Below the other end of the transverse connecting rod 204c, a transverse trigger rod 204e that meshes with the second wide gear 204d is also provided. One end of the transverse trigger rod 204e meshes with the second arc-shaped surface 102b, and the other end is also fixedly provided with a third spring 204f. The two ends of the transverse connecting rod 204c are also provided with serrations at corresponding positions, and mesh with the first wide gear 203f-1 and the second wide gear 204d respectively. The end of the transverse trigger rod 204e is smooth. When the nozzle 201 moves to the left or right to spray to a distance, the transverse trigger rod 204e is squeezed by the second arc surface 102b and moves, driving the second wide gear 204d to rotate, which in turn drives the transverse connecting rod 204c to move, and then drives the first wide gear 203f-1 to rotate. Then the same movement process as described in the previous paragraph occurs, that is, the arc plate 202a gradually slides down along the conical surface of the nozzle 201, and the orifice diameter of the nozzle 201 becomes smaller. The third spring 204f is a compression spring and plays a role in resetting.

[0048] Furthermore, the trigger 204 also includes a manual pressing rod 204g disposed at the end of the spray gun housing 103. One end of the manual pressing rod 204g is fixedly connected to the moving ring 203b, and a fourth spring 204h is disposed around the other end of the manual pressing rod 204g and outside the spray gun housing 103. This invention can be adaptively adjusted as well as manually adjusted. That is, when the operator manually pushes the manual pressing rod 204g, its long connecting rod will also push the moving ring 203b to move, thereby controlling the movement of the arc plate 202a and thus controlling the size of the nozzle 201 orifice.

[0049] In use, the flushing device is first installed downstream of the trash rack at the hydroelectric power station, directly facing the trash rack. When it is necessary to use the water spray gun to flush away the debris accumulated at the trash rack, the operator simply operates the handle 103a to direct the water stream from the nozzle 201 towards the debris. One water pressure is used to flush nearby debris. When flushing debris further away, there are two possibilities: debris at a higher position or debris on the left or right sides. In this case, the nozzle 201 needs to be raised or moved to the left or right. Taking the raised nozzle 201 as an example, when the tail end of the spray gun housing 103 is pressed to raise the nozzle 201, the end of the longitudinal trigger rod 204a inside the spray gun housing 103 will be squeezed by the first arc-shaped surface 102a on the top column 102, gradually moving towards the nozzle 201, and driving the first wide gear 203f-1 to rotate, which in turn drives the swing arm 203e to swing and push the moving ring 203b to move. At this time, the arc-shaped plate 202a will gradually slide down along the conical surface of the nozzle 201, and the orifice of the nozzle 201 will become smaller. Under the condition that the pressure of the booster pump remains unchanged, the water flow from the nozzle 201 outlet will spray further, thus meeting the need to clean up garbage at a distance. The principle is the same when the nozzle 201 swings to the left or right. This device can also be manually adjusted, that is, when the operator manually pushes the manual pressing rod 204g, its long connecting rod will also push the moving ring 203b to move, that is, control the movement of the arc-shaped plate 202a, thereby controlling the size of the nozzle 201 orifice.

[0050] It should also be noted that the spray gun housing 103 has corresponding chambers or grooves inside, allowing all the aforementioned components to be installed properly. This device, through the configuration of the spray gun assembly and adjustment assembly, can adaptively change the orifice diameter at the water gun nozzle, thereby altering the water flow rate and pressure to meet the rinsing needs of different distances.

[0051] Example 3

[0052] Reference Figure 10 The third embodiment of the present invention provides a trash rack flushing system, which includes a water pumping and storage unit 300 and a flushing unit 400. The water pumping and storage unit 300 provides the water source needed for flushing the trash, and the flushing unit 400 directly flushes the trash.

[0053] Specifically, the pumping and storage unit 300 includes a pumping assembly 301 and a booster assembly 302 connected to the pumping assembly 301. The pumping assembly 301 includes a pump 301a and a storage tank 301b connected to the pump 301a via a pipeline. A maintenance valve 301c and an electric ball valve 301d for the storage tank are sequentially installed on the pipeline between the pump 301a and the storage tank 301b. The pump 301a can be referenced as model 100-100-5.5 water pump, with a specific parameter of 100m³ / h. 3 The pump 301a, with a capacity of 380V and a speed of 12.5m, directly draws water from the reservoir through its inlet pipe and then flows into the storage tank 301b for sedimentation via its outlet pipe. The maintenance valve 301c at the front end of the storage tank is normally open and closed during maintenance of the storage tank 301b. The electric ball valve 301d at the front end of the storage tank opens when the storage tank 301b is replenished and remains closed under normal conditions.

[0054] The booster assembly 302 includes a booster pump 302a connected to the water storage tank 301b via a pipeline. A safety valve 302b is installed on the outlet pipeline of the booster pump 302a. A booster pump inlet valve 302c is installed on the pipeline between the booster pump 302a and the water storage tank 301b. A spray gun hose 302d and a flushing hose 302e are connected to the outlet of the safety valve 302b. Both the spray gun hose 302d and the flushing hose 302e are equipped with a flushing pipeline front-end valve 302f. The spray gun hose 302d is connected to the flushing device P. The booster pump inlet valve 302c is normally fully open and is fully closed when the booster pump 302a or the water storage tank 301b is under maintenance. The booster pump 302a is a reference model 40-250-7.5 water pump, 6.3 m³ / h, 380V, 80m. Safety valve 302b ensures pressure relief when the outlet water pressure is too high, ensuring the safety of the pipeline and booster pump 302a.

[0055] Preferably, the flushing unit 400 includes a flushing device P connected to the pressurization component 302 and a sewage discharge component 401. The sewage discharge component 401 includes a sewage discharge gun 401a connected to the flushing hose 302e and an electric slide rail 401b disposed on one side of the trash rack, with the sewage discharge gun 401a fixed to the electric slide rail 401b. As described in Embodiment 2, the flushing device P uses high-pressure water flow to flush away debris on the trash rack. The electric slide rail 401b can move the sewage discharge gun 401a according to the water level in the reservoir area, using high pressure to flush away debris floating at the inlet of the trash rack and debris washed off by the flushing device P, causing them to leave the inlet and enter the sewage discharge gate.

[0056] During operation, pump 301a draws water from the reservoir area to storage tank 301b for sedimentation. When the trash rack absorbs too much trash, booster pump 302a is activated to raise the water pressure to 0.8 MPa. The operator then uses flushing device P to flush the area where trash has absorbed the trash. Simultaneously, upstream of the trash rack, sewage discharge gun 401a flushes away any falling trash, directing it away from the inlet and into the discharge gate, thus preventing the trash from re-entering the trash rack. This system can also be used to flush trash in shallow water areas.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
