Description

Technical Field

[0001] The invention belongs to the technical field of geothermal recharge, and in particular relates to an automatic monitoring device for geothermal recharge. Background Art

[0002] Geothermal energy is increasingly gaining worldwide attention as a clean energy source. By digging production wells and reinjection wells on the soil layer, and extracting geothermal water from the production wells for utilization, a certain amount of tail water is reasonably reinjected into the production reinjection wells to maintain the balance of extraction and replenishment of geothermal water resources. Utilizing geothermal resources in a circulating manner is a model for sustainable resource utilization. Since the reinjection tail water is directly injected into the wellbore during reinjection, it is easy to form water columns of different heights, causing obvious changes in the water level in the well, which will lead to errors in the monitoring data such as water level and water temperature obtained. Summary of the invention

[0003] The purpose of the present invention is to provide a geothermal recharge automatic monitoring device to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The automatic monitoring device for geothermal reinjection includes a connecting plate and a monitoring pipe. A buffer module is arranged above the connecting plate. A flow expansion module is connected between the buffer module and the connecting plate. A supporting module is connected to the bottom of the buffer module. A monitoring module is arranged on the buffer module. A floating ring is connected to the bottom edge of the connecting plate. The bottom end of the monitoring pipe passes through the buffer module, the connecting plate and the floating ring and is connected to a water level monitor. A stabilizing module is connected between the flow expansion module and the monitoring pipe. Gap modules are arranged on the outer wall of the connecting plate and the buffer module.

[0006] Preferably, the buffer module includes a buffer plate, an arresting ring and a circular through hole. The buffer plate is arranged above the connecting plate, the arresting ring is connected to the top edge of the buffer plate, and the circular through hole array is opened in the buffer plate, and the circular through hole passes through the buffer plate from top to bottom. After the tail water is recharged into the recharge well, the recharged tail water is received by the buffer plate to prevent the tail water from directly impacting the water in the recharge well to form water columns of different heights, thereby reducing the obvious degree of water level change in the well. After the tail water falls into the buffer plate, it is blocked by the arresting ring, so that the tail water is concentrated on the top of the buffer plate, and the tail water enters the supporting pipe through the two circular through holes located on the outside.

[0007] The diameter of the circular surface of the buffer plate is consistent with the diameter of the circular plate of the connecting plate;

[0008] The bottom end of the monitoring pipe passes through the buffer plate, the connecting plate, and the floating ring in sequence, and is connected to the water level monitor;

[0009] A sealing ring is provided on the left side of the top of the connecting plate, and the sealing ring is sleeved on the outer wall of the monitoring tube to enhance the sealing effect and stability of the connection between the monitoring tube and the connecting plate.

[0010] Preferably, the flow expansion module includes a flow expansion pipe, a transfer chamber, a primary conduit, a deep well pump, an assembly plate and a secondary conduit. The flow expansion pipe array is connected between the bottom of the buffer plate and the connecting plate, and the top of the flow expansion pipe is connected to the circular through hole, the bottom of the flow expansion pipe is connected to the transfer chamber, the deep well pump is arranged in the middle below the connecting plate, the assembly plate is symmetrically connected to both sides of the top of the deep well pump, the top surface of the assembly plate is fitted with the connecting plate, and the assembly plate is fixedly connected to the connecting plate by positioning bolts, and the primary conduit is connected between the deep well pump and the connecting plate. The top of the first-level conduit passes through the connecting plate and is connected to the transfer chamber. The second-level conduit is connected to the bottom of the deep well pump. When the deep well pump is turned on, the tail water on the top of the buffer plate is guided to the bottom of the device through the circular through hole in the middle, the expansion pipe, the transfer chamber, the first-level conduit and the second-level conduit in sequence, thereby completing the confluence of the tail water into the water liquid, providing an additional confluence method for the tail water on the top of the buffer plate, increasing the amount of tail water confluence, preventing tail water from accumulating on the buffer plate, thereby preventing more tail water from accumulating on the buffer plate and affecting the water level monitoring accuracy of the water level monitor.

[0011] Preferably, the support module includes a support pipe and a flow slot. The support pipe array is connected to the bottom end of the buffer plate, and the bottom end of the support pipe is connected to the connecting plate. A circular array of flow slots is opened at the bottom end of the support pipe. The tail water enters the support pipe and flows to the top of the connecting plate through the flow slot, and then flows into the water in the recharge well from the top edge of the connecting plate, thereby improving the calmness of the tail water flowing into the water in the recharge well.

[0012] Preferably, the monitoring module includes a hollow rod, a hollow circular plate, a floating plate, an equipment slot and a contact switch, the floating plate is arranged on the right side of the top of the buffer plate, the hollow rod is connected to the bottom end of the floating plate, and the bottom end of the hollow rod passes through the buffer plate, the hollow circular plate is connected to the bottom end of the hollow rod, the equipment slot is opened above the right side of the inner wall of the blocking ring, and the contact switch is embedded in the equipment slot. When the tail water inflow is less than the tail water recharge volume, the tail water will accumulate at the top of the buffer plate, and the tail water level at the top of the buffer plate will rise, so that the floating plate drives the hollow rod and the hollow circular plate to rise. When the floating plate rises to contact with the contact switch, the contact switch transmits data to the external terminal, and the external terminal receives the data and controls the deep well pump to start;

[0013] A limiting plate is connected to the upper right side of the inner wall of the arresting ring, and the bottom surface of the limiting plate is flush with the top surface of the equipment slot, providing a certain limiting effect for the floating plate to prevent the floating plate from continuing to rise and above the contact switch.

[0014] Preferably, the stabilizing module includes a stabilizing ring, a vertical plate and a transverse plate. The stabilizing ring is sleeved under the outer wall of the secondary conduit. The transverse plates are symmetrically connected to the two sides of the outer wall of the stabilizing ring. The vertical plates are symmetrically arranged on both sides of the secondary conduit, and the bottom end of the vertical plate is connected to the transverse plate, and the top end of the vertical plate is connected to the connecting plate, so as to enhance the stability of the secondary conduit.

[0015] Preferably, the stabilization module also includes an auxiliary circular hole and a counterweight block. The auxiliary circular hole is opened in the horizontal plate located on the left side, and the auxiliary circular hole penetrates the horizontal plate up and down. The bottom end of the monitoring tube penetrates the auxiliary circular hole, and the counterweight block is connected to the right side of the top end of the horizontal plate located on the right side. The setting of the auxiliary circular hole can prevent the horizontal plate located on the left side from affecting the use of the monitoring tube, and the setting of the counterweight block can offset the weight of the monitoring tube and the water level monitor on the left side, so that the device itself can be more stably placed in the water of the recharge well.

[0016] Preferably, the gap module includes a primary ball head and a secondary ball head. The circumferential array of the primary ball heads is arranged on the outer wall of the retaining ring, and the circumferential array of the secondary ball heads is arranged on the outer wall of the connecting plate. Through the primary ball head and the secondary ball head, a certain gap is left between the device and the wall of the reinjection well. This not only facilitates the arrangement of the device in the reinjection well, but also ensures that there is a certain gap between the outer wall of the connecting plate and the wall of the reinjection well, thereby ensuring that the tail water can smoothly flow down from the top edge of the connecting plate and merge into the water in the reinjection well.

[0017] Compared with the prior art, the beneficial effect of the present invention is that when the present invention is in use, when the tail water is recharged into the excavated recharge well, the recharged tail water will fall onto the buffer plate, and through the buffering of the buffer plate, under the action of gravity, the tail water will pass through the circular through holes, the supporting pipes and the flow slots in sequence and fall to the top of the connecting plate, and then flow into the water in the recharge well from the top edge of the connecting plate, preventing the tail water from directly impacting the water in the recharge well to form water columns of different heights, reducing the obvious degree of water level changes in the well, and when the tail water inflow is less than the tail water recharge amount, the expansion module is used to provide an additional inflow method for the tail water on the top of the buffer plate, thereby increasing the tail water inflow and preventing tail water from accumulating on the buffer plate, thereby preventing a large amount of tail water from accumulating on the buffer plate, and ensuring the accuracy of the water level monitor when performing automatic water level monitoring.

The buffer plate 31 is arranged above the connecting plate 1, and the blocking ring 32 is connected to the top edge of the buffer plate 31. The circular through hole 33 array is opened in the buffer plate 31, and the circular through hole 33 passes through the buffer plate 31 from top to bottom. After the tail water is recharged into the recharge well, the recharged tail water is received by the buffer plate 31 to prevent the tail water from directly impacting the water in the recharge well to form water columns of different heights, thereby reducing the obvious degree of water level change in the well. After the tail water falls into the buffer plate 31, it is blocked by the blocking ring 32, so that the tail water is concentrated on the top of the buffer plate 31, and the tail water enters the support pipe 51 through the two circular through holes 33 located on the outside.

[0028] The diameter of the circular surface of the buffer plate 31 is consistent with the diameter of the circular plate of the connecting plate 1;

[0031] refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the flow expansion module 4 includes a flow expansion pipe 41, a transfer chamber 42, a primary conduit 43, a deep well pump 44, an assembly plate 45 and a secondary conduit 46. The flow expansion pipe 41 array is connected between the bottom of the buffer plate 31 and the connecting plate 1, and the top of the flow expansion pipe 41 is connected to the circular through hole 33, and the bottom of the flow expansion pipe 41 is connected to the transfer chamber 42. The deep well pump 44 is arranged in the middle below the connecting plate 1, and the assembly plate 45 is symmetrically connected to both sides of the top of the deep well pump 44. The top surface of the assembly plate 45 is in contact with the connecting plate 1, and the assembly plate 45 is fixedly connected to the connecting plate 1 through positioning bolts. The primary conduit 43 is connected to the deep well pump 44. Between the connecting plate 1, the top of the primary conduit 43 passes through the connecting plate 1 and is connected to the transfer chamber 42. The secondary conduit 46 is connected to the bottom of the deep well pump 44. The deep well pump 44 is turned on to guide the tail water on the top of the buffer plate 31 to the bottom of the device through the circular through hole 33 in the middle, the expansion pipe 41, the transfer chamber 42, the primary conduit 43 and the secondary conduit 46 in sequence, thereby completing the tail water into the water liquid, providing an additional inflow method for the tail water on the top of the buffer plate 31, increasing the tail water inflow amount, preventing the accumulation of tail water on the buffer plate 31, thereby preventing more tail water from accumulating on the buffer plate 31 and affecting the water level monitoring accuracy of the water level monitor 8.

[0032] refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the support module 5 includes a support pipe 51 and a flow slot 52. The support pipe 51 array is connected to the bottom end of the buffer plate 31, and the bottom end of the support pipe 51 is connected to the connecting plate 1. The flow slot 52 is opened in a circular array at the bottom end of the support pipe 51. The tail water enters the support pipe 51 and flows to the top of the connecting plate 1 through the flow slot 52, and then flows into the water in the reinjection well from the top edge of the connecting plate 1, thereby improving the calmness of the tail water flowing into the water in the reinjection well.

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the monitoring module 6 includes a hollow rod 61, a hollow circular plate 62, a floating plate 63, an equipment slot 64 and a contact switch 65. The floating plate 63 is arranged on the right side of the top of the buffer plate 31, the hollow rod 61 is connected to the bottom end of the floating plate 63, and the bottom end of the hollow rod 61 passes through the buffer plate 31, the hollow circular plate 62 is connected to the bottom end of the hollow rod 61, the equipment slot 64 is opened above the right side of the inner wall of the blocking ring 32, and the contact switch 65 is embedded in the equipment slot 64. When the amount of tail water inflow is less than the amount of tail water recharge, the tail water will accumulate at the top of the buffer plate 31, and the tail water level at the top of the buffer plate 31 will rise, so that the floating plate 63 drives the hollow rod 61 and the hollow circular plate 62 to rise. When the floating plate 63 rises to contact with the contact switch 65, the contact switch 65 transmits data to the external terminal, and the external terminal receives the data and controls the deep well pump 44 to start;

[0034] A limiting plate 66 is connected to the upper right side of the inner wall of the blocking ring 32 , and the bottom surface of the limiting plate 66 is flush with the top surface of the equipment slot 64 , providing a certain limiting effect for the floating plate 63 to prevent the floating plate 63 from continuing to rise and being higher than the contact switch 65 .

[0035] refer to Figure 1-Figure 6 As shown, the stabilizing module 9 includes a stabilizing ring 91, a vertical plate 92 and a horizontal plate 93. The stabilizing ring 91 is sleeved under the outer wall of the secondary duct 46, and the horizontal plate 93 is symmetrically connected to both sides of the outer wall of the stabilizing ring 91. The vertical plate 92 is symmetrically arranged on both sides of the secondary duct 46, and the bottom end of the vertical plate 92 is connected to the horizontal plate 93, and the top end of the vertical plate 92 is connected to the connecting plate 1, so as to enhance the stability of the secondary duct 46.

[0036] refer to Figure 1-Figure 6As shown, the stabilization module 9 also includes an auxiliary circular hole 94 and a counterweight 95. The auxiliary circular hole 94 is opened in the horizontal plate 93 located on the left, and the auxiliary circular hole 94 passes through the horizontal plate 93 from top to bottom. The bottom end of the monitoring tube 2 passes through the auxiliary circular hole 94, and the counterweight 95 is connected to the right side of the top end of the horizontal plate 93 located on the right. The setting of the auxiliary circular hole 94 prevents the horizontal plate 93 located on the left from affecting the use of the monitoring tube 2, and the setting of the counterweight 95 can offset the weight of the monitoring tube 2 and the water level monitor 8 on the left, so that the device itself can be more stably placed in the water of the reinjection well.

[0037] refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the gap module 10 includes a primary ball head 101 and a secondary ball head 102. The primary ball heads 101 are arranged in a circumferential array on the outer wall of the retaining ring 32, and the secondary ball heads 102 are arranged in a circumferential array on the outer wall of the connecting plate 1. Through the primary ball heads 101 and the secondary ball heads 102, a certain gap is left between the device and the wall of the reinjection well, which not only facilitates the arrangement of the device in the reinjection well, but also ensures that there is a certain gap between the outer wall of the connecting plate 1 and the wall of the reinjection well, thereby ensuring that the tail water can smoothly flow down from the top edge of the connecting plate 1 and merge into the water in the reinjection well.

[0038] Working principle: the bottom end of the monitoring pipe 2 is passed through the buffer plate 31, the connecting plate 1, and the floating ring 7 in sequence, and is connected to the water level monitor 8. The device is placed in the recharging well dug in the soil layer, and the device is floated on the water in the recharging well through the floating ring 7. After the tail water is recharged into the recharging well, the recharged tail water is received by the buffer plate 31 to prevent the tail water from directly impacting the water in the recharging well and forming water columns of different heights, thereby reducing the obvious degree of water level change in the well. After the tail water falls into the buffer plate 31, it is blocked by the blocking ring 32, so that the tail water is concentrated on the top of the buffer plate 31, and through the two circular through holes 33 located on the outside, the tail water enters the supporting pipe 51, and flows to the top of the connecting plate 1 through the flow slot 52, and then merges into the water in the recharging well from the top edge of the connecting plate 1, thereby improving the calmness of the tail water merging into the water in the recharging well.

[0039] When the amount of tail water inflow is less than the amount of tail water recharge, the tail water will accumulate at the top of the buffer plate 31, and the tail water level at the top of the buffer plate 31 will rise, so that the floating plate 63 drives the hollow rod 61 and the hollow circular plate 62 to rise. When the floating plate 63 rises to contact with the contact switch 65, the contact switch 65 transmits data to the external terminal, and the external terminal receives the data and controls the deep well pump 44 to start, and guides the tail water at the top of the buffer plate 31 through the circular through hole 33 in the middle, the expansion pipe 41, the transfer chamber 42, the primary conduit 43 and the secondary conduit 46 to the bottom of the device in sequence, thereby completing the tail water inflow into the water liquid, providing an additional inflow method for the tail water at the top of the buffer plate 31, increasing the amount of tail water inflow, preventing tail water accumulation on the buffer plate 31, thereby preventing more tail water from accumulating on the buffer plate 31 and affecting the water level monitoring accuracy of the water level monitor 8;

[0040] As the tail water on the top of the buffer plate 31 is gradually pumped into the water below the device, the content of the tail water on the top of the buffer plate 31 gradually decreases, causing the tail water level to lower, thereby causing the floating plate 63 to descend. When the floating plate 63 is separated from the contact switch 65, the contact switch 65 transmits a signal to the external terminal, which receives the data and controls the deep well pump 44 to shut down, thereby stopping the operation of the flow expansion module 4.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
