DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5 As shown, the present invention is a geothermal recharge automatic monitoring device, comprising a positioning frame 1, a reduction motor 7 is fixedly mounted on the top surface of the positioning frame 1, a coupling shaft 14 is fixedly mounted on the output end of the reduction motor 7, and a fixed frame 19 is fixedly connected to the surface of the coupling shaft 14;

[0025] There are two groups of fixed frames 19, one of which has a motor fixedly installed inside, and connecting seats 20 are symmetrically fixedly installed on the facing surfaces of the two groups of fixed frames 19, and the surface of the connecting seat 20 is rotatably connected with a straight shaft 23, one of which is fixedly connected to the output end of the motor, and the surface of the straight shaft 23 is symmetrically fixedly connected with a toothed wheel 21, and the surface of the toothed wheel 21 is sleeved with a sleeve belt 22, and the surface of the sleeve belt 22 is clamped and fixed with a clamping seat 24, and one end surface of the clamping seat 24 is symmetrically rotatably connected with a connecting pipe 25;

[0026] A recharging bin 2 is fixedly connected to the inner side of the positioning frame 1, a recharging pipe 3 is welded and fixed to the bottom surface of the recharging bin 2, a slag discharge bin 4 is welded and fixed to one end surface of the positioning frame 1, a monitoring window is provided on the top surface of the slag discharge bin 4, a flap 5 is rotatably connected to the top surface of the slag discharge bin 4, and a pouring groove 6 is provided near the middle of the top surface of the recharging bin 2;

[0027] A positioning seat is fixedly installed near the middle of the two end surfaces of the refilling bin 2, a driving wheel 8 is arranged on the surface of the positioning seat, a belt 9 is sleeved and connected to the surface of the driving wheel 8, a driven wheel 10 is rotatably connected near the side edge of the two end surfaces of the refilling bin 2, a discharge roller 11 is fixedly connected to the surface of the driven wheel 10, and an arc frame 12 is fixedly installed inside the refilling bin 2;

[0028] The surface of the arc frame 12 is equidistantly provided with through slits 13, and the bottom end of the through slits 13 is provided with leakage holes. During the geothermal reinjection operation, the user can pre-connect the reinjection device with the injection tank 6 according to the operation requirements to ensure that the connection between the injection tank 6 and the reinjection system is stable and effective. At this time, the geothermal tail water will be introduced into the reinjection tank 2. When entering this process, the flow speed and flow rate of the tail water need to be accurately controlled to avoid excessive impact on the system when the tail water is injected into the reinjection tank 2. After the geothermal tail water is injected into the reinjection tank 2, it will gradually limit the flow and flow out through the multiple leakage holes in the through slits 13 to achieve the effect of stable flow control. In this process, through the setting of flow limiting, the stability of the tail water flow rate can be stably controlled, and the impact force caused by the tail water reinjection on the reinjection well can be effectively reduced, so as to prevent the tail water from flowing out too quickly. The impact recharges the well water, thereby forming a height difference of the water column, causing significant fluctuations in the water level in the well and unstable water level changes. This stable flow control not only reduces the operating risk of the system, but also helps to reduce the possible pollution of the tail water to the environment. At the same time, in the process of geothermal tail water passing through the permeable seam 13, the entrained solid impurities will inevitably be blocked at the permeable seam 13, and some impurities will be stuck in the small holes in the permeable seam 13, forming a blockage. In order to ensure that these impurities will not have an adverse effect on the subsequent tail water recharge, the role of the connecting shaft 14 is very critical. The connecting shaft 14 connects and drives the discharge roller 11. Through its stable rotation, the stuck solid impurities are gradually removed to avoid excessive accumulation of these impurities in the subsequent recharge process, thereby affecting the flow and injection effect of the tail water;

[0029] The connecting shaft 14 is fixedly connected to the transmission wheel 8, and a cross frame 15 is fixedly connected to the surface of the connecting shaft 14. A positioning block 16 is symmetrically fixedly connected to the surface of one end of the cross frame 15. A connecting frame 17 is fixedly connected to the two short sides of the cross frame 15. A scraping groove 18 is provided on the surface of the connecting frame 17. The rotation of the connecting shaft 14 mainly depends on the driving action of the reduction motor 7. The working efficiency of the reduction motor 7 determines the stability of the reinjection system and the control accuracy of the flow rate. In this way, the impurities are transported to the lower end under the drive of the discharge roller 11, and are finally brought into the slag discharge bin 4 through the coordinated action of the transmission wheel 8, the belt 9 and the driven wheel 10. In the slag discharge bin 4, these solid impurities will eventually fall out through the preset opening, thereby reducing the pollution caused by impurities in the tail water to the environment and maintaining the cleanliness of the reinjection process. During the normal geothermal tail water reinjection operation, the user can regularly open the flap 5 to directly check the reinjection situation inside the reinjection bin 2 to ensure that the entire system is in normal working condition and timely discover possible abnormal situations. The opening of the flap 5 The operation of the recharging bin 2 becomes easier, and the user can check and adjust the tail water recharging status at any time. At this time, through reasonable monitoring means, the operator can adjust the flow rate of the tail water at any time to ensure the smooth progress of the recharging process and avoid problems such as violent fluctuations in the water level in the well caused by out-of-control flow. In order to better clean up solid impurities and avoid excessive impact force during the operation of the system, the connection between the connecting shaft 14 and the positioning seat can rotate periodically under the driving action of the reduction motor 7. During the rotation process, the connecting frame 17 will continuously reciprocate toward the arc frame 12 with the periodic movement of the connecting shaft 14. In this process, the surface scraping groove 18 of the connecting frame 17 cooperates with the through seam 13 to effectively scrape off the solid impurities stuck therein, avoid the accumulation of these impurities, and affect the smooth recharging of the tail water. The design of the scraping groove 18 can ensure efficient cleaning of solid impurities. The regular stirring action can not only remove the stuck impurities, but also reduce the impact strength of the tail water, and avoid unnecessary pressure on the recharging system.

[0030] The surface of the positioning block 16 is fixedly connected with a stabilizing rail 27, and the surface of the stabilizing rail 27 is slidably connected with a stabilizing seat 28. The stabilizing seat 28 is fixedly connected to the clamp seat 24, and the surface of the connecting pipe 25 is symmetrically provided with through grooves 26. Because the fixed frame 19 is installed on the inner side of the cross frame 15, the continuous rotation of the connecting shaft 14 makes the entire recharging process more stable and stable, and at the same time can avoid the adverse effects caused by the tail water impact. In order to further improve the stability of the system, the fixed frame 19 is installed on the inner side of the cross frame 15. When the connecting shaft 14 rotates, the cooperation of the fixed frame 19 and other components can effectively avoid excessive vibration of the system. At the same time, the user can drive the rotation of the straight shaft 23 by starting the motor. The straight shaft 23 is connected to another straight shaft 23 through the sleeve belt 22. The sleeve belt 22 drives the rotation of the other straight shaft 23, thereby controlling the periodic movement of the clamp seat 24. The clamp seat 24 continuously reciprocates through the cooperation between its surface and the sleeve belt 22. In this way, the sleeve belt 22 can control the clamp seat 24 as the motor periodically flips. Displacement, the clamp seat 24 is constantly moving, and the position of the connecting pipe 25 is mainly controlled to change. The position change of the connecting pipe 25 will cause turbulence in the tail water flow, forming a disturbed flow, thereby effectively reducing the impact force of the tail water reinjection. In addition, the generation of turbulence is also helpful to further screen out impurities in the tail water, and prevent impurities from being brought into the reinjection well through the through seam 13. Through this method, the impact of tail water on the system can be reduced, and impurities in the tail water can be cleaned out of the reinjection system in time. In addition, in order to ensure the stable movement of the clamp seat 24, the design of the stabilizing rail 27 is very important. The cooperation of the stabilizing rail 27 and the stabilizing seat 28 can provide a strong supporting effect, ensuring that the clamp seat 24 maintains stable operation during the reinjection process, avoiding deformation of the sleeve 22 due to the impact of the tail water or affecting the normal operation of the reinjection system. The stabilizing rail 27 not only ensures the smooth movement of the clamp seat 24, but also can stabilize the flow state of the tail water when the tail water flow rate changes, and avoid excessive fluctuations from having adverse effects on the system.

[0031] Working principle of the present invention: During geothermal reinjection operation, the user can pre-connect the reinjection device with the injection tank 6 according to the operation requirements to ensure that the connection between the injection tank 6 and the reinjection system is stable and effective. At this time, the geothermal tail water will be introduced into the reinjection tank 2. When entering this process, the flow rate and flow rate of the tail water need to be precisely controlled to avoid excessive impact on the system when the tail water is injected into the reinjection tank 2. After the geothermal tail water is injected into the reinjection tank 2, it will gradually flow out through the multiple leakage holes in the through seam 13 to achieve the effect of stable flow control. In this process, through the setting of flow limiting, it is possible to stably control the stability of the tail water flow rate and effectively reduce the impact force caused by the tail water reinjection on the reinjection well, thereby preventing the tail water from impacting the reinjection well water too quickly, thereby The height difference of the water column causes significant fluctuations in the water level in the well and produces unstable water level changes. This stable flow control not only reduces the operating risk of the system, but also helps to reduce the possible pollution of the tail water to the environment. At the same time, in the process of geothermal tail water passing through the permeable seam 13, the entrained solid impurities will inevitably be blocked at the permeable seam 13, and some impurities will be stuck in the small holes in the permeable seam 13, forming a blockage. In order to ensure that these impurities will not have an adverse effect on the subsequent tail water reinjection, the role of the coupling 14 is very critical. The coupling 14 connects and drives the discharge roller 11, and through its stable rotation, the stuck solid impurities are gradually removed to avoid excessive accumulation of these impurities in the subsequent reinjection process, thereby affecting the flow and injection effect of the tail water. The rotation of the shaft 14 mainly depends on the driving action of the reduction motor 7. The working efficiency of the reduction motor 7 determines the stability of the reinjection system and the control accuracy of the flow rate. In this way, the impurities are transported to the lower end of the discharge roller 11, and are finally brought into the slag discharge bin 4 through the coordinated action of the transmission wheel 8, the belt 9 and the driven wheel 10. In the slag discharge bin 4, these solid impurities will eventually fall out through the preset opening, thereby reducing the pollution of the environment caused by impurities in the tail water and maintaining the cleanliness of the reinjection process. During the normal geothermal tail water reinjection operation, the user can regularly open the flap 5 to directly check the reinjection situation inside the reinjection bin 2 to ensure that the entire system is in normal working condition and to promptly discover possible abnormal situations. The opening of the flap 5 The operation of the recharging bin 2 becomes easier, and the user can check and adjust the tail water recharging status at any time. At this time, through reasonable monitoring means, the operator can adjust the flow rate of the tail water at any time to ensure the smooth progress of the recharging process and avoid problems such as drastic fluctuations in the water level in the well caused by out-of-control flow. In order to better clean up solid impurities and avoid excessive impact force during system operation, the connection between the connecting shaft 14 and the positioning seat can rotate periodically under the driving action of the reduction motor 7. During the rotation, the connecting frame 17 will continuously reciprocate towards the arc frame 12 with the periodic movement of the connecting shaft 14. In this process, the cooperation between the surface scraping groove 18 of the connecting frame 17 and the through slit 13 can effectively scrape off the solid impurities stuck therein.In order to avoid the accumulation of these impurities and affect the smooth reinjection of tail water, the design of the scraper groove 18 can ensure the efficient cleaning of solid impurities. The regular stirring action can not only remove the stuck impurities, but also reduce the impact strength of the tail water, and avoid unnecessary pressure on the reinjection system. Because the fixed frame 19 is installed on the inner side of the horizontal frame 15, the continuous rotation of the connecting shaft 14 makes the entire reinjection process more stable and stable, and at the same time can avoid the adverse effects caused by the impact of tail water. In order to further improve the stability of the system, the fixed frame 19 is installed on the inner side of the horizontal frame 15. When the connecting shaft 14 rotates, the cooperation of the fixed frame 19 and other components can effectively avoid excessive vibration of the system. At the same time, the user can start the motor to drive the rotation of the straight shaft 23. The straight shaft 23 is connected to another straight shaft 23 through the sleeve belt 22. The sleeve belt 22 drives the rotation of the other straight shaft 23, thereby controlling the periodic movement of the clamp seat 24. The clamp seat 24 continuously reciprocates through the cooperation between its surface and the sleeve belt 22. In this way, the sleeve belt 22 can move with the periodicity of the motor. The displacement of the clamp seat 24 is controlled by flipping. During the continuous movement of the clamp seat 24, the position of the connecting pipe 25 is mainly controlled to change. The position change of the connecting pipe 25 will cause the turbulence of the tail water flow and form a disturbed flow, thereby effectively reducing the impact force of the tail water reinjection. In addition, the generation of turbulence also helps to further screen out impurities in the tail water and prevent impurities from being brought into the reinjection well through the through seam 13. In this way, the impact of the tail water on the system can be reduced, and the impurities in the tail water can be cleaned out of the reinjection system in time. In addition, in order to ensure the stable movement of the clamp seat 24, the design of the stabilizing rail 27 is very important. The cooperation of the stabilizing rail 27 and the stabilizing seat 28 can provide a strong supporting effect to ensure that the clamp seat 24 maintains stable operation during the reinjection process, and avoids deformation of the sleeve 22 or affecting the normal operation of the reinjection system due to the impact of the tail water. The stabilizing rail 27 not only ensures the smooth movement of the clamp seat 24, but also stabilizes the flow state of the tail water when the tail water flow rate changes, and avoids excessive fluctuations from having adverse effects on the system.
