When the ultrahigh-voltage wellhead device is used, the wellhead device 1 is installed, the water outlet channel 2 and the water inlet channel 3 are respectively communicated with an external pipeline, and geothermal water with pressure enters from the water inlet channel 3;
when water needs to be discharged, the separation disc 4 is rotated through the driving assembly at the moment, the middle flow channel 5 in the separation disc enables the water inlet channel 3 and the water outlet channel 2 which correspond to each other in a crossed mode to be communicated, as shown in fig. 6, geothermal water can flow out of the water outlet channel 2 at the moment, and in the process, impurities in the geothermal water are filtered by the filtering assembly;
when the filter assembly is blocked and needs to be cleaned, the driving assembly drives the separating disc 4 to rotate and switch at the moment, so that the communicated water outlet channel 2 and the communicated water inlet channel 3 are switched, and the filter assembly in the flow channel is convenient to clean;
in the process, due to the fact that the pressure and the flow velocity of the geothermal water are very high under the action of high pressure in the earth crust, when the separation disc 4 rotates and is switched, the separation disc can be influenced by a large water hammer effect when the rotating speed is high, and large impact force is caused on the separation disc 4, and therefore when the separation disc 4 rotates to interrupt the water inlet channel 3, the pressure relief assembly arranged in the separation disc can relieve the pressure in the water inlet channel 3 with the interruption of the separation, so that the influence caused by the water hammer effect is reduced or counteracted, and the impact damage effect on the separation disc 4 is reduced;

In one preferred embodiment, the pressure relief assembly comprises a counteracting hole 8 formed in the outer wall of the cambered surface of the separating disc 4, the counteracting hole 8 is communicated with the interior of the middle flow channel 5, a push rod 9 is slidably mounted in the counteracting hole 8, and an elastic piece used for counteracting the water pressure in the water inlet channel 3 is mounted between the inner wall of the counteracting hole 8 and the push rod 9.
Specifically, referring to fig. 6, when the separating disc 4 is rotated and switched, one of the water inlet channels 3 is closed, and meanwhile, the offsetting holes 8 on the separating disc 4 are also communicated with the water inlet channels 3 along with the rotation of the separating disc 4, at this time, under the water pressure of the hot water in the water inlet channels 3, the water flows into the offsetting holes 8, and the ejector rod 9 is pushed to move, so that the water pressure of the ejector rod has a bursting opening, and then the pressure and the shock waves of the water flow are offset by the elastic force of the elastic member, thereby achieving the purpose of reducing or eliminating the influence of the water hammer effect, and further achieving the purpose of protecting the separating disc 4.
In one preferred embodiment, the filtering component comprises a circular groove 6 arranged at the center of the separating disc 4, a filtering net 7 is rotatably arranged on the inner wall of the center of the circular groove 6, and the edge of the filtering net 7 is attached to the arc-shaped inner wall of the circular groove 6;
be located between the arc inner wall of the circular recess 6 of filter screen 7 both sides and the filter screen 7 and be connected with first spring 16, after filter screen 7 lost geothermal water's impact force, first spring 16 was used for driving filter screen 7 and rotates to be the vertical state with the axis of mesolow 5.
Specifically, referring to fig. 6, when the local hot water passes through the middle flow passage 5, the local hot water is filtered by the filter screen 7 inside the local hot water, so that impurities such as sand in the water are removed;
and under the impact of high-pressure geothermal water, in order to prevent the filter screen 7 from turning over by 180 degrees, therefore install the first spring 16, is used for offsetting the impact force of the rivers, and through the setting of circular slot 6, when the rivers pass through the filter screen 7, the inner wall of circular slot 6 under the circular slot 6, namely deposit the ground 15, the rivers can form the backward flow at the place 15 that deposits and is the vortex, the rivers of its position are compared with the rivers velocity of flow in the centre of well flow channel 5 and is smaller, therefore some impurity under filtering can block in the filtration pore of filter screen 7, and another part can be deposited at the place 15 that deposits gradually under the guide of gravity, filter screen 7 inclined plane and rivers, used for concentrating and collecting the impurity, so as to facilitate the subsequent cleaning.
In one preferred embodiment, the wellhead device 1 is provided with an outer arc groove 10 at the periphery of the separating disc 4, and the outer arc groove 10 is provided with a rotating baffle plate 11 which is coaxial with the separating disc 4;
the separating disc 4 is connected with the rotating baffle 11 through a transmission assembly, the transmission assembly enables the separating disc 4 and the rotating baffle 11 to rotate in opposite directions, only the front section of the rotating stroke of the separating disc 4 drives the rotating baffle 11 to rotate through the transmission assembly, the offsetting hole 8 is blocked in advance through the rotating baffle 11, and the inner arc surface of the rotating baffle 11 is provided with a pressure relief groove for relieving pressure of the offsetting hole 8;
the counter bore 8 communicates with the circular recess 6 and hits the filter sieve 7 when the rod 9 extends into the circular recess 6.
Referring to fig. 6, it can be seen from the foregoing that the push rod 9 moves into the circular groove 6 and impacts the filter screen 7 along with the action of the water pressure while the elastic member eliminates the water pressure;
because the two offsetting holes 8 are symmetrically arranged relative to the middle flow channel 5, when the middle flow channel 5 rotates to a vertical position in the rotating process of the separating disc 4, the two offsetting holes 8 are simultaneously and respectively communicated with the two water inlet channels 3, so that the filter screen 7 can be damaged because the two ejector rods 9 simultaneously extend into the circular groove 6, and the purpose of arranging the rotating baffle plate 11 is to prevent the two offsetting holes 8 from being simultaneously communicated with the water inlet channels 3;
referring to fig. 6-9, in the process of rotating the separating disc 4, the front section drives the rotating baffle 11 to reversely rotate against the separating disc 4 through the transmission assembly, so when the middle flow channel 5 in the separating disc 4 rotates to the vertical state, at this time, under the action of the rotating baffle 11, one of the offsetting holes 8 is shielded and sealed, so that only one ejector rod 9 extends into the circular groove 6 under the action of water pressure, namely, as shown in the enlarged part in fig. 6, the filter screen 7 cannot be damaged, and then when the separating disc 4 continues to rotate, the rear section of the separating disc 4 cannot drive the rotating baffle 11 to rotate through the transmission assembly, so as to avoid the middle flow channel 5 from being shielded due to the continuous rotation of the rotating baffle 11;
it should be noted that the relative position between the rotating baffle 11 and the separating disc 4 after the rotating process is finished will not affect the central flow channel 5, as shown in fig. 6.
In one of the preferred embodiments, the inner walls of the two water inlet channels 3 are both provided with a notch groove, and the fan wheel 14 is rotatably mounted in the notch groove, so that the geothermal water in the water inlet channels 3 can impact the fan wheel 14 to rotate when flowing;
the automatic excitation device further comprises a self-excitation assembly for detecting the rotation state of the fan wheel 14, and when the self-excitation assembly detects that the rotation state of the fan wheel 14 is converted into a specified state, the self-excitation assembly controls the driving assembly to drive the separating disc 4 to rotate and switch.
Specifically, referring to fig. 6, when the water inlet channel 3 is in a communicated state, the flow of the water flow inside the water inlet channel may impact the fan wheel 14 to rotate, and the flow rate may be affected due to the blockage of the filter screen 7, so the flow rate of the water flow in the water inlet channel 3 may also be affected, and therefore the rotation state of the fan wheel 14 may be detected by the self-excitation assembly, and the blockage of the filter screen 7 and the internal impurities may be determined, so that the driving assembly is controlled to drive the separation disc 4 to rotate and switch, so as to clean the impurities.
In one preferred embodiment, the self-excitation assembly includes two detection blocks 21 disposed outside the wellhead device 1, the two detection blocks 21 are coaxially fixed with the two fan wheels 14, the outer wall of the wellhead device 1 is provided with counting assemblies 22 for counting the number of rotation turns of the detection blocks 21, when the number of rotation turns of the detection blocks 21 exceeds a preset value, the counting assemblies 22 control the driving assembly to drive the separation disc 4 to rotate and switch, and the detection blocks 21 detected by the counting assemblies 22 are switched accordingly.
Referring to fig. 10, in this embodiment, the counting assembly 22 is used to detect the rotation speed of the detecting block 21 coaxially fixed with the fan wheel 14, and when the rotation number of the detecting block reaches a preset value, the counting assembly 22 will control the driving assembly to start, so as to drive the separating disc 4 to rotate and switch.
Example two, substantially the same as example one, except that a second implementation of the self-energizing assembly is provided, see in particular fig. 11;
the self-excitation assembly comprises two power generation assemblies 23, the two power generation assemblies 23 are respectively connected with the rotating shafts of the two fan blades 14, the power generation assemblies 23 connected with the fan blades 14 can be driven to generate power when the fan blades 14 rotate, and the power generation assemblies 23 control the driving assemblies to drive the separating disc 4 to rotate and switch when the generated energy reaches a specified limit.
In this embodiment, the rotation of the fan wheel 14 can be used to drive the power generation assembly 23 to generate power, until the generated energy reaches a specified limit, the control triggers the driving assembly to start, and the achieved effect is basically the same as that of the embodiment, and can also be used as a timing switching mode;
in the third embodiment, basically the same as the first embodiment, except that a third implementation manner of the self-energizing assembly is provided, specifically referring to fig. 12, that is, the counting assembly 22 in the first embodiment is replaced with a rotation speed testing assembly 24 for testing the rotation speed of the detecting block 21, because when the filter screen 7 is clogged, the flow rate of the water in the water inlet channel 3 is also correspondingly reduced, and the rotation speed of the fan wheel 14 is also reduced, so when the rotation speed testing assembly 24 detects that the rotation speed of the detecting block 21 is reduced to a preset value, the rotation speed testing assembly 24 triggers the driving assembly to start, and the embodiment is different from the two embodiments described above in that the fan wheel 14 has the greatest influence on the rotation speed, so that the embodiment is suitable for more impurities, and can be switched according to the clogging condition of the filter screen 7.
It is worth mentioning that the counting assembly 22, the rotation speed testing assembly 24 and the power generation assembly 23 can be implemented by using an infrared sensor and an electromagnetic power generation structure.

As can be seen from fig. 1-6, when the filter screen 7 is blocked, the driving assembly drives the separating disc 4 to rotate, so as to switch the water inlet channel 3 and the water outlet channel 2;
in the process, when the middle flow channel 5 in the separating disc 4 rotates to be in a vertical state, the middle flow channel 5 is communicated with the separating groove 12, and at the moment, water in the middle flow channel 5 above the filter screen 7 falls down to flush impurities at the settling place 15, so that the impurities fall into the containing box 13 below;
in the process, the ejector rod 9 extends into the circular groove 6 to knock the filter screen 7, so that the filtered impurities on the filter screen are shaken off, and the filter screen 7 is cleaned under the flow of water above the filter screen, so that the cleaning effect is improved;
and ejector pin 9 can drive its rotation when knocking filter screen 7, and its edge part can rotate along circular recess 6, will deposit the impurity of place 15 and play a scraping's effect, further improves the clean effect of inside impurity, then behind the solid-liquid separation of containing box 13, can clear away impurity.
In conclusion, the filter screen 7 is cleaned in the process of switching the rotation of the separating disc 4, and the pressure relief assembly can improve the cleaning effect of the filter screen 7 while reducing or eliminating the water hammer effect.
It is worth mentioning that the thickness between the separation tank 12 and the water inlet channel 3 is larger than the diameter of the middle flow channel 5, so as to avoid the communication between the separation tank 12 and the water inlet channel 3 through the middle flow channel 5.
In addition, the reset action of the first spring 16 on the filter screen 7 can also avoid the collision of the filter screen 7 with the stroke of the ejector rod 9 due to the overlarge rotation angle, so as to ensure the impact action of the ejector rod 9 on the filter screen 7.
