Description

Technical Field

[0001] This utility model relates to the technical field of seepage monitoring devices, and in particular to a reservoir seepage monitoring device. Background Technology

[0002] Reservoir seepage monitoring is one of the important means to ensure the safe operation of reservoirs. During heavy rain or torrential rain, the reservoir water level rises, and moisture in the soil in the reservoir area can seep into the soil inside and outside the reservoir through cracks, pores and other channels, causing fluctuations in the reservoir water level, and may even lead to serious consequences such as dam breach or collapse.

[0003] Most reservoir seepage detection devices typically use electronic sensors or wireless transmission modules to detect reservoir seepage, and employ a manual feed table to polish hardware components. However, this method of reservoir seepage detection requires continuous power supply to the device body and maintenance of the circuit system. In some remote reservoirs without power or in extreme weather conditions, it is impossible to maintain a stable working state, reducing monitoring efficiency and affecting monitoring results. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that differs from the existing technology. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reservoir seepage monitoring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reservoir seepage monitoring device includes a fixed frame, a pressure chamber fixedly connected inside the fixed frame, a piston head slidably connected inside the pressure chamber, a piston rod fixedly connected to the top of the piston head, a fixed block fixedly connected to one end of the piston rod, a rack fixedly connected to one side of the fixed block, a housing fixedly connected to the outside of the pressure chamber, a scale fixedly connected inside the housing, a rotating shaft rotatably connected to one side of the scale via a bearing, a pointer keyed to one side of the rotating shaft, and a gear keyed to one end of the rotating shaft passing through the pressure chamber, with the rack meshing with the gear.

[0007] As a further embodiment of this utility model, a guide pipe is fixedly connected to the bottom of the pressure chamber, and a conical water collection bucket is fixedly connected to one end of the guide pipe.

[0008] As a further embodiment of this utility model, a fixed shaft is fixedly connected to both sides of the fixed frame, a limit block is fixedly connected to one side of each of the two fixed shafts, and a mounting base is rotatably connected to the outer side of each of the two fixed shafts.

[0009] As a further improvement of this utility model, each of the two mounting bases has two insertion holes on one side, and ground nails are slidably connected in the plurality of insertion holes.

[0010] As a further embodiment of this utility model, a sleeve is fixedly connected to one side of each of the two mounting bases, and the two sleeves rotate along a fixed axis. Threaded holes are opened on the outer sides of the two sleeves, and screws are threaded into the two threaded holes.

[0011] As a further improvement of this utility model, a filter screen is fixedly connected inside the conical water collecting hopper.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model is equipped with a piston, which can move the piston and piston rod through seepage water, causing the rack to drive the gear to rotate, thereby causing the pointer to rotate and reflecting the pressure or flow rate of the seepage water. This can increase monitoring efficiency and reduce the impact of monitoring results in some reservoirs without power or in extreme weather conditions.

[0014] 2. This utility model is equipped with a conical water collection hopper, which can increase the area of ​​the device for collecting seepage water, so that the seepage water can flow into the water collection hopper more evenly and fully, thereby improving the overall water collection efficiency.

[0015] 3. This utility model is equipped with a filter screen, which can filter out the mud or impurities mixed in the seepage water, preventing mud and sand from entering the pressure chamber and affecting the piston, thereby causing errors in subsequent monitoring data.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Referring to Figures 1-3, a reservoir seepage monitoring device includes a fixed frame 1. A pressure chamber 3 is fixed inside the fixed frame 1 by bolts. A piston head 16 is slidably connected inside the pressure chamber 3. A piston rod 15 is welded to the top of the piston head 16. A fixing block 14 is welded to one end of the piston rod 15. A rack 12 is fixed to one side of the fixing block 14 by bolts. A housing 4 is welded to the outside of the pressure chamber 3. A scale 2 is bonded inside the housing 4. A rotating shaft 11 is rotatably connected to one side of the scale 2 via a bearing. A pointer 10 is keyed to one side of the rotating shaft 11. One end of the rotating shaft 11 passes through the pressure chamber 3 and is keyed to a gear 13. The rack 12 meshes with the gear 13. In use, water is guided to flow against gravity into the pressure chamber 3. At this time, the water pressure pushes the piston head 16 to move along the inner wall of the pressure chamber 3, thereby driving the piston rod 15 and the fixing block 14 to move upward. This causes the rack 12 to move and simultaneously drive the gear 13 meshing with it. The rotation of the pointer 10 simultaneously causes the pointer 10 to rotate, displaying the seepage flow rate on the dial 2. This increases monitoring efficiency and reduces the impact of monitoring results in reservoirs without power or in extreme weather conditions.

[0022] In this utility model, a guide pipe 7 is bolted to the bottom of the pressure chamber 3, and a conical water collection bucket 9 is bolted to one end of the guide pipe 7. In use, the conical water collection bucket 9 can increase the area of ​​the device for collecting seepage water, so that the seepage water can flow into the water collection bucket more evenly and fully, thereby improving the overall water collection efficiency. Fixed shafts 18 are welded to both sides of the fixed frame 1, and limit blocks are welded to one side of each of the two fixed shafts 18. Mounting seats 6 are rotatably connected to the outer side of each of the two fixed shafts 18. Two insertion holes 17 are opened on one side of each of the two mounting seats 6, and ground nails 5 are slidably connected in the multiple insertion holes 17. The mounting seats 6 can be rotated along the axis of the fixed shafts 18 through the fixed shafts 18. Then, the mounting seats 6 are installed on the slope of the dam body through the ground nails 5, thereby adjusting the working angle of the pressure chamber 3, so as to monitor seepage water in different directions and increase the convenience of the device.

[0023] In particular, sleeves 19 are welded to one side of each of the two mounting bases 6, and the two sleeves 19 rotate along the fixed shaft 18. Threaded holes are opened on the outer sides of the two sleeves 19, and screws 20 are threaded into the two threaded holes. In use, the screws 20 can be tightened to make them contact the fixed shaft 18, thereby fixing the position of the mounting base 6 and increasing the stability of the device. A filter screen 8 is fixed inside the conical water collecting hopper 9 by bolts. In use, the filter screen 8 can filter out the mud or impurities mixed in the seepage water, preventing mud and sand from entering the pressure chamber 3 and affecting the piston, thus causing errors in subsequent monitoring data.

[0024] Working principle: When monitoring a reservoir is required, the mounting base 6 is placed on the downstream slope of the reservoir dam or near the drainage prism. The conical water collection bucket 9 is aligned with the seepage water, making it perpendicular to the flow direction of the seepage water. The water flow is guided against gravity into the pressure chamber 3 through the conical water collection bucket 9 and the guide pipe 7. At this time, the water pressure pushes the piston head 16 to move along the inner wall of the pressure chamber 3, thereby driving the piston rod 15 and the fixed block 14 to move upward. This causes the rack 12 to move and drive the gear 13 meshing with it to rotate, while simultaneously driving the pointer 10 to rotate, displaying the seepage flow rate on the dial 2. This can increase monitoring efficiency and reduce the impact of monitoring results in some reservoirs without power or in extreme weather conditions.

[0025] Furthermore, although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
