[0005] Beneficial effects: By communicatively connecting the main control unit with the second sensor and the first sensor, it is used to receive the measurement data of the second sensor and the first sensor, and calculate the height of the solid suspended matter according to the measurement data. Since the float structure is slidably connected with the fixed bracket in the vertical direction, and the second sensor is fixedly connected with the float structure, it can ensure that the second sensor is always below the liquid level and slides in the vertical direction along with the change of the liquid level. Combined with the first sensor, it is not affected by the change of the liquid level, enhances the applicability and improves the measurement accuracy. And because the second sensor slides in the vertical direction, the measurement beam direction of the second sensor forms a fixed angle with the horizontal direction, avoiding the solid suspended matter with an unstable thickness formed by the turbulence at the junction of the horizontal well pipeline and the shaft pipeline, making the measured height of the solid suspended matter more accurate.

No matter what the height (thickness) of the second sensor and the buoy part is, the corresponding height can be subtracted during calculation.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] The following combines Figures 1 to 16 , to describe the embodiments of the present utility model.

[0045] According to an embodiment of the present utility model, a monitoring device is provided, including a fixed support 1, a floating structure 3, a first sensor 4, a second sensor 6 and a main control 7; the fixed support 1 is fixed in the shaft pipe 2; the floating structure 3 is slidably connected to the fixed support 1 in the vertical direction; the first sensor 4 is connected to the fixed support 1 and is arranged at the top of the horizontal well pipe 5 for measuring the height from the first sensor 4 to the liquid level in the horizontal well pipe 5; the horizontal well pipe 5 is located at the bottom of the shaft pipe 2 and is communicated with the shaft pipe 2; the second sensor 6 is connected to the floating structure 3 for measuring the height from the second sensor 6 to the surface of the solid suspended matter in the horizontal well pipe 5; the main control 7 is communicatively connected to the first sensor 4 and the second sensor 6.

[0046] It is communicatively connected to the second sensor 6 and the first sensor 4 through the main control 7, and is used to receive the measurement data of the second sensor 6 and the first sensor 4, and calculate the height of the solid suspended matter according to the measurement data. Since the float structure 3 is slidably connected to the fixed bracket 1 in the vertical direction, and the second sensor 6 is fixedly connected to the float structure 3, it can be ensured that the second sensor 6 is always below the liquid level and slides in the vertical direction as the liquid level changes. When combined with the first sensor 4, it is not affected by the liquid level change, enhancing the applicability and improving the measurement accuracy. And because the second sensor 6 slides in the vertical direction, the measurement beam direction of the second sensor 6 forms a fixed angle with the horizontal direction, avoiding the solid suspended matter with an unstable thickness formed by the turbulence at the junction of the horizontal well pipe 5 and the vertical well pipe 2, making the measured height of the solid suspended matter more accurate.

[0047] Specifically, the vertical well pipe 2 is a vertical well, and the horizontal well pipe 5 is a horizontal pipe communicating with the vertical well.

[0048] Specifically, the solid suspended matter in this application refers to solid particles suspended in a liquid, and its size is usually above 0.45 microns. These particles can come from various sources, including soil erosion, industrial emissions, urban runoff, agricultural activities, and metabolic products of aquatic organisms, etc. The solid suspended matter can include sand, silt, slag, metal oxides, etc. Silt is preferred.

[0049] In a specific embodiment, the first sensor 4 is a liquid level monitoring device for monitoring the liquid level. Specifically, the first sensor 4 can be a liquid level gauge.

[0050] In a specific embodiment, the second sensor 6 is a monitoring device for monitoring the solid suspended matter. Specifically, the second sensor 6 can be a sludge level gauge.

[0051] Preferably, the second sensor 6 is fixed at the bottom of the float structure 3, which can ensure that the second sensor 6 is always below the liquid level and slides in the vertical direction as the liquid level changes.

[0052] In a specific embodiment, the main control 7 is fixed at the top of the well wall of the vertical well pipe 2 for facilitating the observation of the height data of the solid suspended matter on the wellhead; the main control 7 includes a main controller and a power supply; specifically, the power supply is a battery. The first sensor 4 and the second sensor 6 can be connected and communicate with the main control 7 through cables, or can communicate with the main control 7 wirelessly.

[0053] In a specific embodiment, as Figure 3 shown, when the liquid level is lower than the top of the horizontal well pipe 5, H x = H0 - H1 - H2 - H3.

[0054] Among them, H xH is the height of the solid suspension; H0 is the height of the inner wall of the horizontal well pipe 5, that is, the inner diameter of the horizontal well pipe 5; H1 is the height from the bottom of the first sensor 4 to the top of the horizontal well pipe 5, that is, the height of the first sensor 4 itself; H2 is the height from the first sensor 4 measured by the first sensor 4 to the liquid level; H3 is the height from the second sensor 6 measured by the second sensor 6 to the surface of the solid suspension.

[0055] In one embodiment, the fixing bracket 1 further includes a conduit 11, and the conduit 11 is arranged on the wall of the vertical well pipe 2 in the vertical direction; the floating structure 3 includes a sliding rod 31 and a floating part 32; the sliding rod 31 is slidably inserted into the conduit 11 along the length direction of the conduit 11; the floating part 32 is fixedly connected to the bottom of the sliding rod 31, and the outer diameter of the floating part 32 is greater than the inner diameter of the conduit 11.

[0056] Through the arrangement of the conduit 11 and the sliding rod 31, the sliding direction of the floating structure 3 can be limited to ensure that the floating structure 3 slides in the vertical direction; through the arrangement of the floating part 32, it can be ensured that the floating structure 3 is always in contact with the liquid level and slides in the vertical direction all the time as the liquid level changes; and since the outer diameter of the floating part 32 is greater than the inner diameter of the conduit 11, the floating part 32 can always be located at the bottom of the conduit 11 and will not be inserted into the conduit 11 along with the sliding rod 31.

[0057] Specifically, the shape of the floating part 32 can be circular or polygonal, and can be selected according to the actual situation. The outer diameter of the floating part 32 refers to the diameter of the largest circumscribed circle of the floating part 32 in the horizontal direction.

[0058] Specifically, the shape of the conduit 11 can be cylindrical or cuboid, and can be selected according to the actual situation. The inner diameter of the conduit 11 refers to the diameter of the largest inscribed circle of the conduit 11 in the horizontal direction.

[0059] In one embodiment, through holes are provided on the side wall of the conduit 11; the fixing bracket 1 further includes a collar 12 and a sliding wheel 13; the collar 12 is sleeved on the outer periphery of the conduit 11; the sliding wheel 13 includes a fixed end and a sliding end, the fixed end is fixedly connected to the collar 12, and the sliding end passes through the through hole so that the sliding rod 31 slides along the length direction of the conduit 11.

[0060] Through the arrangement of the sliding wheel 13, the sliding connection between the sliding rod 31 and the conduit 11 can be realized; by setting the collar 12, the fixing between the sliding wheel 13 and the conduit 11 is realized.

[0061] In a specific implementation manner, the fixed end of the sliding wheel 13 can be fixedly connected to positions such as the inner wall, bottom, and top of the collar 12, and is preferably fixedly connected to the inner wall of the collar 12.

[0062] In a specific embodiment, at least three collars 12 are sequentially and spaced apart along the length direction of the conduit 11, and each collar 12 is correspondingly connected to a sliding wheel 13. Specifically, each collar 12 is connected to at least four sliding wheels 13, and at least four of the sliding wheels 13 are sequentially and spaced apart along the circumferential direction of the collar 12. Specifically, the sliding rod 31 is a rectangular rod, and the four sliding wheels 13 are respectively in sliding contact with four surfaces on the outer periphery of the rectangular rod.

[0063] In one embodiment, the bottom surface of the conduit 11 and the top surface of the first sensor 4 are at the same height.

[0064] Since the outer diameter of the float portion 32 is greater than the inner diameter of the conduit 11, and the bottom of the conduit 11 and the top surface of the first sensor 4 are at the same height, the bottom surface of the conduit 11 and the top of the horizontal well pipe 5 are approximately at the same height, which can ensure that when the liquid in the horizontal well pipe 5 is in a full pipe state, the reference position can be determined. No matter what the height (thickness) of the second sensor 6 and the float portion 32 is, the corresponding value can be subtracted during calculation. When the liquid level is higher than the top of the horizontal well pipe 5, the height of the solid suspended matter can be calculated by using data such as the fixed inner wall height of the horizontal well pipe 5 and the heights of the second sensor 6 and the float portion 32, thereby greatly improving the applicability and accuracy of the equipment.

[0065] As Figure 4 shown, when the liquid level is higher than the top of the horizontal well pipe 5, the second sensor 6 rises to the bottom of the conduit 11 along with the float portion 32 and is flush with the bottom surface of the first sensor 4. At this time, H2 = 0; H x = H0 - H1 - H3.

[0066] Among them, H x is the height of the solid suspended matter; H0 is the inner wall height of the horizontal well pipe 5, that is, the inner diameter of the horizontal well pipe 5; H1 is the data other than the data measured by the second sensor 6 subtracted from the inner diameter of the horizontal well pipe 5, including the height of the float portion 32 and the height of the second sensor 6 itself; H2 is the height measured by the first sensor 4 from the first sensor 4 to the liquid surface; H3 is the height measured by the second sensor 6 from the second sensor 6 to the surface of the solid suspended matter.

[0067] In one embodiment, the fixed bracket 1 further includes a fixed rod 14, the fixed rod 14 is fixed on the wall of the shaft pipe 2 in the vertical direction, and the conduit 11 is fixedly connected to the fixed rod 14.

[0068] By setting the fixed rod 14, the fixation of the conduit 11 can be achieved. The assembly of the conduit 11 and the buoy structure 3 can be carried out on the ground, and the conduit 11 is fixedly connected to the fixed rod 14. The conduit 11 and the buoy structure 3 are placed below the shaft pipeline 2 through the fixed rod 14, realizing the installation of the buoy structure 3 without going down the well, which is convenient for installation and saves time and effort.

[0069] In a specific embodiment, the conduit 11 and the fixed rod 14 are fixedly connected by a hoop.

[0070] In one embodiment, the fixed bracket 1 further includes a fixed crossbar 15. The fixed crossbar 15 is arranged at the top of the horizontal well pipeline 5, and one end is connected to the bottom of the fixed rod 14, and the other end extends along the axial direction of the horizontal well pipeline 5 and is connected to the first sensor 4.

[0071] Through the setting of the fixed crossbar 15, it is helpful to fix the first sensor 4 at the top of the horizontal well pipeline 5, realizing the installation of the first sensor 4 without going down the well, and making the installation process of the first sensor 4 simpler, reducing the installation difficulty of the first sensor 4, and facilitating the installation and fixation of the first sensor 4.

[0072] In one embodiment, the fixed crossbar 15 is a telescopic crossbar.

[0073] By setting the fixed crossbar 15 as a telescopic crossbar, the length of the first sensor 4 extending into the horizontal well pipeline 5 can be adjusted according to actual needs.

[0074] Preferably, one end of the fixed crossbar 15 is threadedly connected to the fixed rod 14, and the other end is connected to the first sensor 4. The fixed crossbar 15 can be a telescopic crossbar, and the length extending into the horizontal well pipeline 5 can be adjusted according to actual needs. Specifically, the length of the telescopic crossbar needs to be determined first, and then the telescopic crossbar is extended into the horizontal well pipeline 5.

[0075] Specifically, the steps of arranging the first sensor 4 can be as follows: first connect the fixed crossbar 15 and the fixed rod 14, then extend from one side of the shaft pipeline 2 opposite to the arrangement position into the horizontal well pipeline 5, and then extend towards the arrangement position to make the first sensor 4 closely fit the inner wall top of the horizontal well pipeline 5.

[0076] Specifically, the fixed crossbar 15 includes a first connecting rod 151 and a second connecting rod 152. Multiple long holes are provided on the first connecting rod 151, and the multiple long holes are arranged at intervals along the length direction of the first connecting rod 151; multiple threaded holes are provided on the second connecting rod 152; the multiple threaded holes are arranged at intervals along the length direction of the second connecting rod 152; fasteners such as bolts can connect different long holes and different threaded holes to realize the adjustment of the length of the fixed crossbar 15.

[0077] In one embodiment, the fixed support 1 further includes a fixing component 16; the fixing component 16 is used to fix the fixing rod 14 to the wall of the shaft pipe 2. The fixing component 16 includes a support rod 161, a first fixing block 162, and a second fixing block 163; an included angle is formed between the support rod 161 and the fixing rod 14; and the length of the support rod 161 is greater than or equal to the inner diameter of the shaft pipe 2; one end of the first fixing block 162 is fixedly connected to the fixing rod 14, and the other end is rotatably connected to one end of the support rod 161; the second fixing block 163 is rotatably connected to the other end of the support rod 161.

[0078] Since the length of the support rod 161 is greater than or equal to the inner diameter of the shaft pipe 2, the support rod 161 can be supported in the shaft pipe 2. And since the support rod 161 is rotatably connected to both the first fixing block 162 and the second fixing block 163, the second fixing block 163 has an unlocking position located below the first fixing block 162 and spaced from the wall of the shaft pipe 2; and a locking position where it moves upward and abuts against the wall of the shaft pipe 2, which facilitates moving the second fixing block 163 from the unlocking position to the locking position.

[0079] In a specific embodiment, the length of the support rod 161 can be 50 mm to 100 mm greater than the inner diameter of the shaft pipe 2.

[0080] Specifically, when the included angle between the support rod 161 and the fixing rod 14 is 90 degrees or close to 90 degrees, the horizontal support length of the support rod 161 is the largest. In actual application, when the fixed support 1 is in the installed state, that is, when the second fixing block 163 is in the locking position, the maximum included angle of the acute angle between the support rod 161 and the fixing rod 14 can be slightly less than 90 degrees.

[0081] In a specific embodiment, the support rod 161 includes a third connecting rod 1611 and a fourth connecting rod 1612. A plurality of first communication holes are provided on the third connecting rod 1611, and the plurality of first communication holes are sequentially arranged at intervals along the length direction of the third connecting rod 1611; a plurality of second communication holes are provided on the fourth connecting rod 1612; the plurality of second communication holes are sequentially arranged at intervals along the length direction of the fourth connecting rod 1612; the inside of the third connecting rod 1611 is a hollow structure, one end of the fourth connecting rod 1612 is inserted into the third connecting rod 1611, and fasteners such as bolts can connect different first communication holes and different second communication holes to realize the adjustment of the length of the support rod 161.

[0082] Specifically, the first fixing block 162 includes a rotating member and a connecting member. One end of the rotating member is a protruding end, and the outer diameter of the protruding end is less than or equal to the inner diameter of the third connecting rod 1611, and is adapted to be inserted and connected with the third connecting rod 1611; the other end of the rotating member protrudes with two first ear plates, and the two first ear plates are arranged at intervals; one end of the connecting member is located between the two first ear plates and is connected to the two first ear plates by bolts and other fasteners; the other end of the connecting member is provided with a connecting hole, and the connecting hole is adapted to be clamped on the outer periphery of the fixing rod 14.

[0083] Specifically, the second fixing block 163 includes a fixing plate and two second ear plates. The two second ear plates are arranged at intervals in sequence and are fixed on the fixing plate. The other end of the fourth connecting rod 1612 is provided with a third ear plate, and the third ear plate is located between the two second ear plates and is fixedly connected to the second ear plates by bolts and other fasteners.

[0084] In one embodiment, a traction structure is further included. The traction structure includes a support member 81 and a traction member 82; the support member 81 is fixed on the top or outside of the shaft pipe 2; one end of the traction member 82 is connected to the support member 81, and the other end is connected to the second fixing block 163.

[0085] By providing the traction member 82, it helps to realize the connection and upward traction of the second fixing block 163. Since the second fixing block 163 is located below the first fixing block 162 when in the unlocking position, it is convenient for the traction structure to upwardly traction the second fixing block 163 so that the second fixing block 163 abuts against the well wall of the shaft pipe 2 and is in the locking position. By providing the support member 81, one end of the traction member 82 can be fixed on the top of the shaft pipe 2, preventing the traction member 82 from falling below the shaft pipe 2, improving the stability of the traction structure; at the same time, it also realizes the installation of the fixing bracket 1 without going down the well. The fixing bracket 1, the first sensor 4 and the second sensor 6 are directly assembled, and the installation and fixation of the monitoring device can be realized without going down the well.

[0086] In a specific embodiment, the support member 81 can be a structure such as a hook; the traction member 82 can be a structure such as a traction rope.
