Description

Technical Field

[0001] This utility model belongs to the field of groundwater monitoring, specifically relating to a groundwater seepage prevention monitoring device for building engineering. Background Technology

[0002] Groundwater seepage prevention monitoring devices for building engineering are used to monitor and prevent groundwater seepage problems. They are especially important in underground engineering projects (such as basements, tunnels, underground parking lots, infrastructure, etc.) because they can ensure that groundwater seepage does not affect the safety and stability of the building.

[0003] Existing groundwater monitoring devices often experience various malfunctions due to the complex environment of underground engineering projects during the monitoring of groundwater seepage prevention in construction projects, thus affecting the effectiveness of groundwater monitoring. Furthermore, traditional mechanical floating monitoring structures often experience errors or jamming due to friction between structures. Since the general floating monitoring structure is relatively fixed, its detection parts are often difficult to adjust flexibly according to the needs of different water level warnings.

[0004] Therefore, in response to the problems of large errors in the use of existing buoyancy-type groundwater seepage prevention monitoring devices and the inconvenience of adjusting the warning water level, a groundwater seepage prevention monitoring device for building engineering is developed. By adding contact-type early warning processing, buoyancy lifting structure and bolt adjustment structure to the groundwater seepage prevention monitoring device, the errors in the use of traditional buoyancy-type groundwater seepage prevention devices can be reduced, the failure rate can be lowered, and it can be flexibly adjusted according to the needs of different warning water levels.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment: a groundwater seepage prevention monitoring device for building engineering, including a shell 1, a support frame 2, a signal transmitter 4, a power supply line 21, and an antenna 22, and also includes a first support plate 3, a limiting frame 5, a connecting block 6, a second support plate 14, and a float 18. The inner walls of the left and right ends of the shell 1 are provided with first grooves 10, the inner walls of the first grooves 10 are fixed to the limiting frames 5, the inner walls of the limiting frames 5 are provided with second sliding grooves 11, the inner walls of the front and rear ends of the shell 1 are provided with first sliding grooves 8, and the outer walls of the front and rear ends of the shell 1 are provided with four sets of equidistantly distributed first screw grooves 9. The upper and lower ends of the connecting block 6 are fixed to the second support plate 14, and the outer walls of the front and rear ends of the second support plate 14 are provided with... There is a connecting groove 15, in which a second pulley 16 is rotatably installed. The left and right ends of the connecting block 6 are rotatably installed with first pulleys 13 via connecting shafts. A button 17 is fixedly connected to the upper center of the second support plate 14 located at the upper end of the connecting block 6. A float 18 is fixedly connected to the lower end of the second support plate 14 located at the lower end of the connecting block 6. The front and rear ends of the first support plate 3 are provided with second threaded grooves 19. Fixing bolts 23 pass through the first threaded grooves 9 and are threaded into the second threaded grooves 19. The upper and lower ends of the first support plate 3 are provided with second grooves 20. A signal transmitter 4 is installed in the second groove 20. The trigger switch of the signal transmitter 4 is located at the lower center and corresponds one-to-one with the button 17.

[0025] The float 18, which is in contact with the groundwater surface, can push the core structure, consisting of two second support plates 14 and a connecting block 6, upward along the inner wall of the outer shell 1 as the water level rises. The first pulley 13 and the second pulley 16 on the core structure can assist the core structure to slide upward stably and smoothly, so as to reduce the resistance caused by friction and affect the accuracy of the core structure's ascent. As the core structure changes with the water level, if it exceeds the warning water level during the ascent, it will push the button 17 to trigger the trigger switch at the lower end of the signal transmitter 4. The signal transmitter 4 will then feed back the water level information to the remote detection terminal to remind the user of the abnormal groundwater level. The equidistantly distributed first screw grooves 9 can be used with the fixing bolts 23 to adjust the trigger position of the signal transmitter 4 according to the height of different warning water levels to meet the needs of different water level warnings.

[0026] Please see Figures 3-6In this embodiment, the first support plate 3 and the second support plate 14 are both movably disposed on the inner wall of the outer shell 1. The first support plate 3 is located above the second support plate 14. The outer walls of the first support plate 3 and the second support plate 14 are in contact with the inner wall of the outer shell 1. In use, the first support plate 3 and the second support plate 14, which are in contact with the inner wall of the outer shell 1, can ensure the installation of the first support plate 3 while also ensuring the stability of the second support plate 14 as it rises and falls with the water surface. The first pulley 13 is disposed within the limiting frame 5. The outer wall of the first pulley 13 is in contact with the second sliding groove 11, and the outer wall of the second pulley 16 is in contact with the inner wall of the first sliding groove 8. In use, the first pulley 13 and the second pulley 16 can improve the smoothness of the second support plate 14 as it rises and falls with the water surface, thereby reducing the error of the water level warning.

[0027] Please see Figures 3-4 In this embodiment, mounting sleeves 7 are fixed to the outer walls of the left and right ends of the outer casing 1. The mounting sleeves 7 are threaded with a support frame 2. In use, the support frame 2 can assist the outer casing 1 in being installed on the inner wall of the groundwater monitoring well and ensure its installation stability. A mounting base 12 is fixed to the upper edge of the support frame 2. The mounting base 12 is bolted to the opening of the groundwater monitoring well. In use, the mounting base 12 can facilitate the user to install the support frame 2 and the outer casing 1 on it into the groundwater monitoring well. The upper and lower ends of the outer casing 1 are open. The first threaded groove 9 and the first sliding groove 8 are interconnected. In use, the upper and lower openings of the outer casing 1 can ensure that groundwater enters from below and cause the second support plate 14 to move upward.

[0028] Please see Figure 6 A power supply line 21 and an antenna 22 are installed on the upper edge of the signal transmitter 4. The signal transmitter 4 is a trigger-type transmission device. When in use, the power supply line 21 can connect the power supply on the ground to the signal transmitter 4 to supply it, while the antenna 22 can ensure the stability of the signal transmitter 4 in feeding back water level information to the remote end.

[0029] When in use, first connect the power supply line 21 to the ground power supply to power the signal transmitter 4, then lower the outer shell 1 of the bearing frame 2 with threads on both sides into the groundwater monitoring well so that the bottom of the float 18 contacts the groundwater surface, and then fix the mounting base 12 to the well opening with bolts.

[0030] When groundwater seeps into the building, the seeping water flows into the groundwater monitoring well, causing the water level to rise. The rising water level will push the float 18 and the core structure consisting of two second support plates 14 and connecting blocks 6 to move upward along the inner wall of the outer shell 1.

[0031] During the movement of the core structure, the first pulley 13 and the second pulley 16 will assist the core structure to move upward in a stable and smooth manner. When the water level exceeds the warning level, the button 17 will be pushed to trigger the trigger switch at the lower end of the signal transmitter 4. The signal transmitter will then feed back the water level information to the remote detection terminal to remind the user of the abnormal groundwater level.

[0032] When it is necessary to adjust the water level warning height, the height of the first support plate 3 inside the housing 1 can be adjusted by turning the fixing bolt 23 and sliding it along the inner wall of the housing 1. After the adjustment is completed, the fixing bolt 23 is passed through the first threaded groove 9 and threaded into the second threaded groove 19 to fix the adjusted first support plate 3, so as to meet the needs of different water level warnings.

[0033] Through the above steps, the float 18, which rises and falls with the water level, propels the core structure, composed of the second support plate 14 and the connecting block 6, to move up and down along the inner wall of the outer shell 1. The first pulley 13 and the second pulley 16 assist the core structure in a stable and smooth lifting and sliding motion, which can reduce the error caused by friction. When the water level exceeds the warning level, the core structure will push the button 17 to trigger the trigger switch at the lower end of the signal transmitter 4. The signal transmitter 4 then feeds back the water level information to the remote detection terminal to remind the user of the abnormal groundwater level. The equidistantly distributed first screw grooves 9 can be used with the fixing bolts 23 to adjust the trigger position of the signal transmitter 4 according to the height of different warning water levels, so as to meet the needs of different water level warnings. This solves the problems of large errors in the use of existing buoyancy-type groundwater seepage prevention monitoring devices and the inconvenience of adjusting the warning water level.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
