[0024] Figure 1 This is a structural schematic diagram of an inclinometer with water pressure and water level acquisition functions in a preferred embodiment of the utility model. DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to the implementation mode, and other implementation modes may also fall within the scope of the present invention as long as they meet the purpose of the present invention.

[0026] In a preferred embodiment of the utility model, based on the above problems existing in the prior art, an inclinometer with water pressure and water level acquisition function is provided. Figure 1 As shown, including:

[0027] A rod body 1, wherein a first accommodating cavity 3 for accommodating a collection mainboard 2 is provided inside the rod body 1, and the collection mainboard 2 is electrically connected to a communication cable 5 installed at the upper end of the rod body 1 through a first through hole 4 opened on the rod body 1;

[0028] The adapter circuit board 6 is installed on the top of the first accommodating cavity 3. An inclinometer 7 is also welded on the adapter circuit board 6. The inclinometer 7 is electrically connected to the acquisition main board 2.

[0029] The pressure monitoring component 8 is installed in the second accommodating chamber 9 opened inside the rod body 1, and a second through hole 10 is opened between the second accommodating chamber 9 and the first accommodating chamber 3. The pressure monitoring component 8 and the acquisition main board 2 are electrically connected through the second through hole 10. The space of the second accommodating chamber 9 except the pressure monitoring component 8 is a water containing chamber 11, and the water containing chamber 11 is opened with a plurality of water inlet holes 12;

[0030] The guide wheel structure 13 is installed on the outer surface of the rod body 1 .

[0031] Specifically, the existing water level meter measurement is a static measurement, generally 2-3 meters from the water surface. If the water level drops, the collected value will be inaccurate.

[0032] Moreover, the groundwater is in the confined water position, the actual water pressure is relatively high, and the water level meter data is not accurate.

[0033] In addition, the inclinometer and water level gauge are measured separately, which not only increases the cost but also may cause problems in data synchronization and calibration.

[0034] Therefore, in order to solve these problems, this embodiment provides an inclinometer with water pressure and water level acquisition functions, which integrates the inclinometer, water pressure and water level acquisition functions into one, realizes the simultaneous measurement of multiple parameters, and improves the measurement efficiency and data accuracy;

[0035] All sensors are integrated into the same device, thus ensuring the synchronization and consistency of the measured data, avoiding the problem of data calibration and synchronization;

[0036] Moreover, compared with the solution of using an inclinometer, a water pressure gauge and a water level gauge respectively, the utility model reduces the number of equipment and the purchase cost.

[0037] When using the inclinometer of the utility model to measure inclination, a method of use that can be adopted is:

[0038] First, lower the inclinometer with water pressure and water level acquisition function to the bottom of the inclinometer pipe. According to the specification requirements, let it stand for 5 minutes to make the inclinometer and the water temperature in the pipe the same.

[0039] Then, pull-up measurements are performed every 0.5 m, and the current horizontal displacement value and water pressure value are obtained at the same time until the pipe mouth is pulled to complete the measurement process.

[0040] The horizontal displacement value is calculated by accumulating the inclinometer data to obtain the deformation of the inclinometer tube. The water pressure value obtained by the pressure monitoring component selects a stable data segment, avoiding the value within 0 to 3m close to the water level and the position of the pressurized water. The measured water depth value is calculated based on the water pressure value. Knowing the measured depth of the data point, the current water level elevation is calculated as = pipe mouth elevation - measured depth + measured water depth value.

[0041] It can be seen that by adopting continuous section measurement to measure the conditions of different groundwater sections, the values ​​calculated by the algorithm are more accurate; and the inclinometer, water pressure and water level acquisition functions are integrated into one, which realizes the simultaneous measurement of multiple parameters and improves the measurement efficiency and data accuracy.

[0042] In a preferred embodiment of the present invention, Figure 1 As shown, the rod body 1 includes a first rod body 110, a second rod body 120, a third rod body 130 and a fourth rod body 140;

[0043] The first rod body 110 and the third rod body 130 are respectively installed at the upper and lower ends of the second rod body 120, and the first accommodating cavity 3 is located inside the second rod body 120;

[0044] The fourth rod body 140 is installed at the bottom of the third rod body 130, the second accommodating chamber 9 is located between the third rod body 130 and the fourth rod body 140, the pressure monitoring assembly 8 is located at the top of the second accommodating chamber 9, and the water containing chamber 11 is located at the bottom of the second accommodating chamber 9 and is divided into a first water containing chamber 111 and a second water containing chamber 112 by a water filter plate 14.

[0046] The second accommodating chamber 9 between the third rod body 130 and the fourth rod body 140 is used for water intake so that the pressure monitoring component 8 can monitor the current water pressure and then calculate the current water level. The monitoring principle and water level calculation process of the pressure monitoring component 8 can be implemented using existing technologies and are not the main invention points of the utility model and will not be repeated here. The water filter plate 14 is mainly used to filter impurities such as sand in the water to avoid damage to the pressure monitoring component 8.

[0048] Specifically, in this embodiment, the first accommodating chamber 3 is formed by the combination of the first rod body 110, the second rod body 120 and the third rod body 130. Since the components contained in each rod body are different, the four-section rod body structure can be flexibly disassembled to replace the acquisition mainboard 2, the pressure monitoring component 8 and other components therein, without opening the entire rod body 1 when a certain component fails, only a part of it needs to be opened, which saves equipment cost, labor cost and time cost of equipment maintenance.

[0049] In a preferred embodiment of the present invention, Figure 1 As shown, the first through hole 4 passes through the first rod body 110, and the first through hole 4 communicates with the first accommodating cavity 3 and the outside of the rod body 1. A waterproof connector 15 is installed on the top of the first rod body 110, and the waterproof connector 15 is connected to the communication cable 5.

[0050] Specifically, in this embodiment, since the first through hole 4 connects the interior and exterior of the rod body 1 , a waterproof terminal 15 is also provided to prevent the connection line between the acquisition mainboard 2 and the communication cable 5 from being short-circuited by water.

[0051] In a preferred embodiment of the present invention, Figure 1 As shown, sealing rings 16 are provided at the connection points between the first rod 110 and the second rod 120 , between the second rod 120 and the third rod 130 , and between the third rod 130 and the fourth rod 140 .

[0053] Furthermore, in order to prevent water from entering the second accommodating chamber 9 and water outside the rod body 1 from entering the first accommodating chamber 3, which may cause a short circuit in the collection main board 2, a sealing ring 16 is provided at the connection of each rod body and is fastened with bolts 17, thereby improving the waterproofness and structural firmness of the rod body 1.

[0054] In a preferred embodiment of the present invention, Figure 1 As shown, Figure 1 As shown, the second through hole 10 passes through the third rod body 130 , and the second through hole 10 communicates with the first accommodating cavity 3 and the second accommodating cavity 9 .

[0055] In a preferred embodiment of the present invention, Figure 1 As shown, a buffer rubber pad 18 is provided at the bottom of the rod body 1.

[0056] Specifically, in this embodiment, a buffer rubber pad 18 is further provided at the bottom of the rod body 1, which is used to play a buffering effect when the bottom of the rod body 1 touches the bottom or side wall of the inclinometer tube, thereby reducing the probability of equipment damage and equipment jitter, and improving the accuracy of data measurement.

[0057] In a preferred embodiment of the present invention, Figure 1 As shown, the guide wheel structure 13 includes at least a pair of upper guide wheels 131 and a pair of lower guide wheels 132 . The upper guide wheels 131 are installed on the outer surface of the first rod body 110 , and the lower guide wheels 132 are installed on the outer surface of the fourth rod body 140 .

[0058] Specifically, in the present embodiment, a plurality of guide wheels are provided. As can be seen from the figure, there are four upper guide wheels 131 and lower guide wheels 132, which are respectively located at the upper left, upper right, lower left and lower right of the rod body 1. Furthermore, the number and position of the guide wheels can be adjusted according to actual conditions, so that when the inclinometer is pulled up for measurement, the guide wheels can be used to move along the wall of the inclinometer tube to obtain the current horizontal displacement value.
