Description

Technical Field

[0001] The invention relates to the technical field of water turbine units, in particular to an inclined turbine unit. Background Art

[0002] The turbine unit is connected to the water supply equipment through the pipeline. The water flows into the turbine, driving the blades of the turbine to rotate, and the rotational mechanical energy is transmitted to the generator, thereby prompting the generator to generate electricity. In the turbine unit, the water flow may contain a certain amount of impurities (such as mud, leaves, sawdust, etc.). After these impurities enter the turbine system, they may affect the efficiency of the turbine and even cause wear or damage to the mechanical parts. In order to protect the turbine system and improve work efficiency, a filter plate is usually installed before the water flows into the turbine. It is designed to effectively filter out solid impurities in the water and prevent them from entering the turbine system, thereby avoiding damage to important components such as blades and bearings. Among them, the filter plate in the water inlet pipeline is easily blocked after long-term use, which affects the continuous flow of subsequent water flow. Therefore, it is necessary to clean the filter plate at set intervals. However, under normal circumstances, it is necessary to disassemble the pipeline where the filter plate is located, and then clean the blocked holes of the filter plate. This method is relatively cumbersome in actual operation, resulting in the problem of difficult cleaning of the filter plate. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an inclined turbine unit to solve the problem of clogging and difficulty in cleaning of the filter plate installed in the water inlet pipe of the turbine mentioned in the background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: an inclined turbine unit, comprising a supply pipeline connected to a turbine assembly, a filter plate installed inside the supply pipeline, a collection assembly interconnected with the supply pipeline installed below the filter plate, and a cleaning mechanism installed on the supply pipeline; The cleaning mechanism includes a cleaning wheel rotatably mounted on a filter plate, a spur gear is mounted in the middle of a side of the cleaning wheel away from the turbine assembly, a single-pass pipe is connected to the top of the supply pipeline, a gear bar connected to the spur gear through a tooth groove is arranged inside the single-pass pipe, and an electric push rod is mounted on the top of the single-pass pipe for driving the cleaning wheel to rotate back and forth repeatedly through the gear bar when extending and retracting up and down.

[0005] Preferably, the cleaning wheel includes a positioning shaft rotatably mounted in the middle of the filter plate, one end of the positioning shaft is fixedly connected to one side of the spur gear, and two mirror-arranged blade brush structures are fixedly mounted on the outer surface of the positioning shaft.

[0006] Preferably, the outer surface of the positioning shaft is equipped with two straight strips which are interlocked with the blade brush structure, and a hole slot plate is installed on the blade brush structure. A circular slot is opened on the straight strip, and a spring structure for passing through the hole slot plate is installed on the bottom wall of the circular slot, and a positioning slot is opened on the top of the spring structure.

[0007] Preferably, a through groove for communicating with a collecting assembly is provided at the bottom of the supply pipeline, and the collecting assembly includes an inlet pipe connected to the supply pipeline and communicated with the through groove, an electromagnetic valve is installed on the inlet pipe, and a collecting cylinder is detachably connected to the bottom of the inlet pipe via a flange.

[0008] Preferably, an arc-shaped sealing plate that fits against the inner wall of the supply pipeline is installed at one end of one of the blade brush structures away from the positioning shaft.

[0009] Preferably, the length and width of the arc-shaped sealing plate are both larger than the diameter of the through slot, and in the initial state when the electric push rod is not extended, the arc-shaped sealing plate covers the through slot, and the top surface of the arc-shaped sealing plate away from the filter plate is inclined.

[0010] Preferably, the central axis of the single-pass pipe coincides with the central axes of the through groove and the inlet pipe, and the inner diameters of the three are consistent; The outer side of the filter plate is pressed against the edge of the through slot close to the turbine assembly.

[0011] Preferably, the turbine assembly includes a runner cavity connected to the supply pipeline and a bearing base installed at the bottom of the runner cavity, a runner main shaft is installed on both sides of the runner cavity, and a connecting plate is installed on the outer surface of the runner main shaft.

[0012] By means of the above technical solution, the present invention provides an inclined turbine unit, which has at least the following beneficial effects: The present invention utilizes a filter plate to intercept impurities in the water flowing along the supply pipeline, preventing the impurities from entering the turbine body with the water flow and causing damage to important structures, and cooperates with an electric push rod to operate at intervals to control the gear bar to move up and down, driving the spur gear to rotate back and forth repeatedly, thereby driving the cleaning wheel to perform a brushing action along the surface of one side of the filter plate, ultimately achieving the purpose of cleaning impurities attached to the surface, thereby effectively reducing the frequency of disassembly and cleaning of the filter plate.

[0013] The blade brush structure and the straight strip plate used in the present invention are in a plug-in combination state, and the spring structure and the hole groove plate are used to increase the firmness of the connection between the two, while ensuring that the blade brush is easy to disassemble when replaced.

[0014] When the filter plate is not cleaned, the present invention uses an arc-shaped sealing plate to cover the entrance channel at the top of the inlet pipe. On the contrary, when the filter plate is cleaned, the solenoid valve is opened relative to the electric push rod, so that impurities in the supply pipeline fall directly into the interior of the collecting cylinder. The overall process effectively avoids impurities in the supply pipeline that are intercepted by the filter plate from contacting the solenoid valve, thereby preventing impurities from being stuck on the internal components of the solenoid valve and causing the valve to become stuck, thereby effectively reducing the frequency of its maintenance.

[0018] Embodiment 1

[0019] In order to effectively solve the problem of clogging and difficulty in cleaning the filter plate installed in the turbine water inlet pipe, please refer to Figure 1-Figure 5 This embodiment proposes an inclined turbine unit, which has a turbine assembly 1 and a supply pipeline 2 connected to its water inlet end. The turbine assembly 1 includes a runner cavity 101 connected to the supply pipeline 2 and a bearing base 102 installed at the bottom of the runner cavity 101. A runner main shaft 103 is installed on both sides of the runner cavity 101, and a connecting plate 104 is installed on the outer surface of the runner main shaft 103. The purpose is to connect an external water supply device through the supply pipeline 2, and put high-velocity water into the runner cavity 101 of the turbine assembly 1, and use the high-velocity water to impact the runner inside the runner cavity 101 to drive its blades to rotate. The rotor of this turbine unit is connected to a generator through the runner main shaft 103, and the mechanical energy generated by the rotation is converted into electrical energy through the rotation of the generator. The filter plate 3 installed inside the supply pipeline 2 is used to effectively remove solid impurities and particulate matter in the water flow, prevent these impurities from entering the interior of the turbine unit, reduce the wear of the blades and other mechanical parts therein, thereby extending the service life of the equipment, and preventing the impurities in the water flow from affecting the rotation efficiency of the turbine unit, thereby improving the overall power generation efficiency of the system. At the same time, the cleaning mechanism 5 installed on the supply pipeline 2 is used to brush and clean the filter plate 3 as needed, thereby reducing the probability of impurities clogging the filter holes therein, and the cleaned impurities are concentratedly transferred to the collection component 4 installed below the filter plate 3 and interconnected with the supply pipeline 2.

[0020] Specifically, the cleaning mechanism 5 includes a cleaning wheel 501 rotatably mounted on the filter plate 3, a spur gear 502 is mounted in the middle of the side of the cleaning wheel 501 away from the turbine assembly 1, a single-pass pipe 503 is connected to the top of the supply pipeline 2, a gear bar 504 connected to the spur gear 502 through tooth grooves is arranged inside the single-pass pipe 503, an electric push rod 505 is installed on the top of the single-pass pipe 503 for driving the cleaning wheel 501 to rotate back and forth repeatedly through the gear bar 504 when it is extended and retracted up and down, the cleaning wheel 501 includes a positioning shaft 5011 rotatably mounted in the middle of the filter plate 3, and one end of the positioning shaft 5011 is fixedly connected to one side of the spur gear 502, two mirror-arranged blade brush structures 5012 are fixedly mounted on the outer surface of the positioning shaft 5011, and a through groove for interconnection with the collection assembly 4 is opened at the bottom of the supply pipeline 2. Figure 2As shown, when cleaning the filter plate 3, the electric push rod 505 is operated to cause it to repeatedly extend downward and retract upward, thereby controlling the gear bar 504 to repeatedly move up and down, thereby driving the spur gear 502 meshing with the gear bar 504 to drive the positioning shaft 5011 to rotate along the middle of the filter plate 3. Based on this, the two blade brush structures 5012 can be controlled accordingly to perform a brushing action along the surface of one side of the filter plate 3, thereby ultimately achieving the purpose of cleaning impurities attached to its surface.

[0021] In accordance with the above, the collecting assembly 4 in this embodiment includes an introduction pipe 401 connected to the supply pipeline 2 and interconnected with the through slot, a solenoid valve 402 is installed on the introduction pipe 401, and a collecting cylinder 403 is detachably connected to the bottom of the introduction pipe 401 through a flange. In the original case, the impurities intercepted by the filter plate 3 will be concentrated on the bottom wall of the supply pipeline 2 near the filter plate 3. In this embodiment, the intercepted impurities will fall into the introduction pipe 401 through the through slot, and then enter the space inside the collecting cylinder 403 for temporary storage, thereby effectively avoiding the accumulation of impurities in the supply pipeline 2. Among them, when the filter plate 3 is not cleaning and transferring the impurities inside the collecting cylinder 403, the solenoid valve 402 is in a closed state to prevent water leakage.

[0022] Embodiment 2

[0023] After frequent use, the bristle end of the blade brush structure 5012 is seriously damaged, which will affect the subsequent cleaning work. Therefore, the blade brush structure 5012 needs to be replaced regularly. In order to facilitate its replacement, Figure 2 and Figure 5As shown, in this embodiment, two straight strips 5013 mutually engaged with the blade brush structure 5012 are installed on the outer surface of the positioning shaft 5011. When the electric push rod 505 drives the positioning shaft 5011 to rotate, the straight strips 5013 rotate accordingly. During the rotation process, the impurities in the supply pipeline 2 can be generated with a rotating thrust, ensuring that more impurities near the filter plate 3 are pushed to the location of the through groove, thereby increasing the efficiency of transferring impurities to the collection cylinder 403. A hole slot plate 5014 is installed on the blade brush structure 5012, and the inner wall of the hole slot plate 5014 is provided with a rubber layer. A circular notch is opened on the straight strip 5013, and a spring structure 5015 for passing through the hole slot plate 5014 is installed on the bottom wall of the circular notch. A positioning groove is opened on the top of the spring structure 5015. The single-pass pipeline 503 itself consists of a straight pipe and a cover detachably connected to the top of the straight pipe through a flange. When the blade brush structure 5012 is actually replaced, the cover is opened, the water supply of the supply pipeline 2 is stopped, and then the blade brush structure 5012 is clamped by a clamp and pulled upward to separate it from the straight strip plate 5013. On the contrary, the blade brush structure 5012 is slid from top to bottom along the clamping groove on the straight strip plate 5013, so that the top of the spring structure 5015 passes through the inside of the hole slot plate 5014, and the elasticity of the rubber layer on the inner wall of the hole slot plate 5014 is used to increase the stability of the combination with the spring structure 5015. In addition, the combination of the two can effectively prevent the blade brush structure 5012 from being excessively squeezed toward the side of the filter plate 3 when the positioning shaft 5011 rotates.

[0024] Embodiment 3

[0025] Following the above-mentioned embodiment 1, under normal circumstances, when the solenoid valve 402 installed on the inlet pipe 401 is closed, there is still a certain distance between the blocking part and the bottom wall of the supply pipeline 2. Impurities are easy to fall into this space, and more impurities are stuck on the internal components of the solenoid valve 402, which can easily cause the valve to be stuck and unable to open or close, affecting its normal operation. In order to effectively solve this problem, Figure 2-Figure 4 As shown, one end of one of the blade brush structures 5012 away from the positioning shaft 5011 is equipped with an arc-shaped sealing plate 5016 that fits with the inner wall of the supply pipeline 2. The length and width of the arc-shaped sealing plate 5016 are both larger than the diameter of the through groove, and in the initial state when the electric push rod 505 is not extended, the arc-shaped sealing plate 5016 covers the through groove, effectively preventing impurities intercepted by the filter plate 3 from falling into the space inside the introduction pipe 401, and before the electric push rod 505 is operated to clean the filter plate 3, the solenoid valve 402 is opened in advance, so the subsequent positioning shaft 5011 rotates to drive the straight plate 5013 to drive the arc-shaped sealing plate 5016. When it is misaligned with the through groove, the impurities inside the supply pipeline 2 fall directly along the introduction pipe 401 to the inside of the collecting cylinder 403, effectively preventing them from staying on the solenoid valve 402, thereby reducing the maintenance frequency of the solenoid valve 402.

[0026] The top surface of the arc-shaped sealing plate 5016 away from the filter plate 3 is inclined to reduce the obstruction to the water flow. The central axis of the single-pass pipe 503 coincides with the central axis of the through groove and the inlet pipe 401, and the inner diameters of the three are consistent. The outer side of the filter plate 3 is pressed against the edge of the through groove close to the turbine assembly 1 to ensure the effective application of the filter plate 3.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
