[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: an automatic sewage discharge device for a water filter of a hydropower unit, including a base 1, a water filter 5 fixedly installed on the top of the base 1, a connecting pipe 4 fixedly installed on one side of the water filter 5, a discharge adjustment mechanism 2 provided below the connecting pipe 4, and a crushing and processing mechanism 3 provided on the top of the discharge adjustment mechanism 2. The discharge adjustment mechanism 2 includes a storage tank 201. The storage tank 201 is located below the connecting pipe 4 and on one side of the base 1. A fixing net 205 is fixedly installed inside the storage tank 201. A pole 206 is fixedly installed inside the storage tank 201 and on the side of the fixing net 205 near the base 1. A foam floating block 210 is slidably connected to the outside of the pole 206 and inside the storage tank 201. An infrared transmitter 207 is fixedly installed near the edge of the pole 206 near the fixing net 205. An infrared receiver 208 is fixedly installed near the edge of the fixing net 205 near the pole 206. A discharge pipe 202 is located at the end of the storage tank 201 away from the base 1. A solenoid valve 204 is fixedly installed at the end of the discharge pipe 202 away from the fixing net 205. A control board 209 is fixedly installed on the side of the storage tank 201 near the base 1. An adjustment component 203 is located on the outside of the discharge pipe 202.

[0021] Specifically, the outer side of the upright 206 and the inner side of the foam floating block 210 are in close contact with each other. By adopting the above technical solution, it is ensured that the upright 206 can guide the foam floating block 210 normally, and that the foam floating block 210 rises and falls smoothly without deviating.

[0022] Specifically, the adjustment component 203 includes a geared motor 2031. The geared motor 2031 is fixedly installed above the storage tank 201 on the side of the connecting pipe 4 away from the water filter 5. A lead screw 2036 is fixedly installed on the side of the geared motor 2031 away from the connecting pipe 4. A moving block 2034 is threaded onto the outside of the lead screw 2036. The moving block 2034 is connected to the discharge pipe 202 through a connecting plate 2037. By adopting the above technical solution, the position of sewage discharge can be adjusted by the cooperation of the lead screw 2036 and the moving block 2034, thereby better meeting the working needs under different conditions.

[0023] Specifically, a sealing ring 2035 is fixedly installed on one side of the storage tank 201 near the edge and outside the discharge pipe 202. By adopting the above technical solution, the sealing ring 2035 can effectively seal the connection between the discharge pipe 202 and the storage tank 201 to prevent sewage leakage.

[0024] Specifically, a protective shell 2032 is fixedly installed above the storage box 201 and outside the geared motor 2031. By adopting the above technical solution, the geared motor 2031 can be protected by the protective shell 2032, thereby reducing the possibility of accidental damage to the geared motor 2031.

[0025] Specifically, a ventilation mesh 2033 is fixedly installed on the top of the protective shell 2032. By adopting the above technical solution, the geared motor 2031 can be ventilated and cooled, thereby reducing the possibility of overheating and damage to the geared motor 2031.

[0026] In this embodiment, when the device is in use, the water filter 5 in the hydroelectric generator discharges sewage to the storage tank 201 in the discharge adjustment mechanism 2 through the connecting pipe 4 for temporary storage. The fixing net 205 prevents impurities from contacting the infrared receiver 208 and other structures. The sewage level gradually rises, pushing the foam floating block 210 to float vertically along the upright 206. When the foam floating block 210 floats to a preset height, it will block the infrared signal between the infrared transmitter 207 and the infrared receiver 208. The infrared receiver 208 cannot receive the signal and immediately transmits a trigger command to the control board 209. After receiving the signal, the control board 209 controls the solenoid valve 204 to open automatically. The sewage and impurities in the storage tank 201 are automatically discharged through the discharge pipe 202, completing the automatic sewage discharge. The base 1 plays a supporting role.

[0027] If it is necessary to adjust the position of the sewage discharge, the geared motor 2031 in the adjustment component 203 can be started, thereby driving the lead screw 2036 to rotate. The lead screw 2036 is threadedly connected to the moving block 2034, and the outer bottom surface of the moving block 2034 is in contact with the outer top surface of the storage tank 201. Therefore, the lead screw 2036 drives the moving block 2034 to move, and then drives the discharge pipe 202 to move synchronously through the connecting plate 2037, thereby adjusting the position of the sewage discharge and better meeting the needs of operation under different conditions. The sealing ring 2035 wraps around the outside of the discharge pipe 202 to ensure the sealing of the storage tank 201 and prevent sewage leakage. The protective shell 2032 protects the geared motor 2031, and the ventilation net 2033 realizes ventilation and heat dissipation.

[0028] Example 2 The difference between this embodiment and embodiment 1 is that the crushing and processing mechanism 3 includes a connecting cylinder 31. The connecting pipe 4 and the storage tank 201 are connected through the connecting cylinder 31. A rotary motor 36 is fixedly installed above the connecting cylinder 31 and on the side of the connecting pipe 4 away from the water filter 5. Multiple crushing blades 33 are fixedly installed on the outer side of the output end of the rotary motor 36 and on the inner side of the connecting cylinder 31. By adopting the above technical solution, large impurities in sewage can be crushed and processed by the cooperation of the crushing blades 33 and other structures, thereby reducing the possibility of blockage and ensuring normal operation.

[0029] Specifically, a filter screen 32 is fixedly installed below the connecting cylinder 31. By adopting the above technical solution, the filter screen 32 can filter out the broken impurities and intercept the unbroken parts, thereby reducing the risk of subsequent pipeline blockage.

[0030] Specifically, a plugging block 34 is threadedly installed on the top of the connecting cylinder 31 on the side of the rotating motor 36 away from the connecting pipe 4. By adopting the above technical solution, the staff can disassemble the plugging block 34 when needed, which facilitates the cleaning and maintenance of the inside of the connecting cylinder 31 and simplifies the device maintenance process.

[0031] Specifically, a transparent window 35 is fixedly installed on the inner side of the blocking block 34. By adopting the above technical solution, the staff can observe the internal condition of the connecting cylinder 31 in real time through the transparent window 35, which facilitates timely detection of abnormalities and improves the controllability of the device.

[0032] In this embodiment, when the sewage is discharged from the connecting pipe 4, it will first enter the connecting cylinder 31 in the crushing and processing mechanism 3. The rotary motor 36 is started, which drives the crushing blade 33 at its output end to rotate at high speed, cutting and crushing large impurities in the sewage, processing large impurities into small particles. The crushed impurities enter the storage tank 201 with the sewage through the filter screen 32 to avoid clogging and damage. At the same time, the blockage block 34 seals the top of the connecting cylinder 31, and the transparent window 35 allows real-time observation of the internal crushing and flow status.

[0033] The working principle and usage process of this invention are as follows: When the device is in use, the water filter 5 in the hydroelectric generator discharges sewage to the storage tank 201 in the discharge adjustment mechanism 2 through the connecting pipe 4 for temporary storage. The fixed net 205 prevents impurities from contacting the infrared receiver 208 and other structures. The sewage level gradually rises, pushing the foam floating block 210 to float vertically along the upright 206. When the foam floating block 210 floats to the preset height, it will block the infrared signal between the infrared transmitter 207 and the infrared receiver 208. The infrared receiver 208 cannot receive the signal and immediately transmits a trigger command to the control board 209. After receiving the signal, the control board 209 controls the solenoid valve 204 to open automatically. The sewage and impurities in the storage tank 201 are automatically discharged through the discharge pipe 202, completing the automatic sewage discharge. The base 1 plays a supporting role.

[0034] If it is necessary to adjust the position of the sewage discharge, the geared motor 2031 in the adjustment component 203 can be started, thereby driving the lead screw 2036 to rotate. The lead screw 2036 is threadedly connected to the moving block 2034, and the outer bottom surface of the moving block 2034 is in contact with the outer top surface of the storage tank 201. Therefore, the lead screw 2036 drives the moving block 2034 to move, and then drives the discharge pipe 202 to move synchronously through the connecting plate 2037, thereby adjusting the position of the sewage discharge and better meeting the needs of operation under different conditions. The sealing ring 2035 wraps around the outside of the discharge pipe 202 to ensure the sealing of the storage tank 201 and prevent sewage leakage. The protective shell 2032 protects the geared motor 2031, and the ventilation net 2033 realizes ventilation and heat dissipation.

[0035] When the sewage is discharged from the connecting pipe 4, it will first enter the connecting cylinder 31 in the crushing and processing mechanism 3. The rotary motor 36 is started, which drives the crushing blade 33 at its output end to rotate at high speed, cutting and crushing large impurities in the sewage, processing large impurities into small particles. The crushed impurities enter the storage tank 201 with the sewage through the filter screen 32 to avoid clogging and damage. At the same time, the blockage block 34 seals the top of the connecting cylinder 31, and the transparent window 35 allows real-time observation of the internal crushing and flow status.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
