[0021] As Figures 1-3 shown in the utility model embodiment provides a kind of plug-in type basic angle steel, including basic main material angle steel 1, support structure is fixed on basic main material angle steel 1, support structure includes support angle steel 2 and connecting angle steel 3, one side of support angle steel 2 is fixed on the outer lateral wall of basic main material angle steel 1, other side is parallel with the section of basic main material angle steel 1, connecting angle steel 3 is fixed on the inner lateral wall of one side of basic main material angle steel 1, the end surface of connecting angle steel 3 is in abutment with the other side of basic main material angle steel 1, the basic main material angle steel 1 and support structure are poured as a whole by concrete, one end of the basic main material angle steel 1 is provided with inclined warning device 4 on horizon.

[0022] In installation process, basic main material angle steel 1 and support structure are fixedly connected, then support structure and basic main material angle steel 1 are inserted into concrete mould according to certain angle, concrete is poured into concrete mould to form tower foundation, by support angle steel 2 is embedded in concrete along with basic main material angle steel 1, the contact area of basic main material angle steel 1 and concrete can be increased, and the resistance of support angle steel 2 in concrete can prevent basic main material angle steel 1 from shaking, to prevent the gap between basic main material angle steel 1 and concrete, support can be provided when basic main material angle steel 1 is bent inwards by connecting angle steel 3, the effect of preventing basic main material angle steel 1 from deforming is achieved, and stable foundation is provided for tower. When tower foundation inclines, inclined warning device 4 can send warning in time, so that maintenance personnel can find and take measures in time, prevent inclination from further aggravating, thereby prolonging the service life of tower and reducing maintenance cost. By using plug-in type basic main material angle steel 1, basic main material angle steel 1 and support structure can be fixedly connected and then inserted into concrete mould as a whole, so that construction process is simplified and construction efficiency is improved. The stability and carrying capacity of overall structure are improved, which directly enhances the safety of tower and reduces the risk of collapse caused by unstable foundation.

[0023] As Figures 1-3 shown, the support structure is multiple, and the connecting angle steel 3 of adjacent support structure is fixed on the two sides of basic main material angle steel 1 respectively. Multiple support structures are evenly distributed around basic main material angle steel 1, which can provide support and stability in multiple directions, help to improve the torsional performance of the whole structure, prevent twisting under uneven load or external force, so that tower foundation is more solid. Interleaved connecting angle steel 3 can more evenly disperse the force exerted by tower, reduce local stress concentration, thereby improving the durability of structure.

[0024] As Figures 1-4As shown, the inclination warning device 4 includes an angle shaft 5 passing through the side wall of the base main material angle steel 1, the end of the angle shaft 5 is provided with a scale angle plate 6, the angle shaft 5 is placed outside the side wall of the base main material angle steel 1 and is screwed with an outer bolt 7, the end of the outer bolt 7 is rotatably connected with a clamping plate 8, the clamping plate 8 can abut against the side wall of the base main material angle steel 1 away from the angle shaft 5, and the end of the angle shaft 5 is rotatably connected with a ruler 9. By arranging the inclination warning device 4 on the base main material angle steel 1 of the plurality of fixed towers, the inclination of the tower in any direction can be detected, and the inclination of the tower can be judged by comparing the data.

[0025] In use, the angle shaft 5 is passed through the angle steel, the clamping plate 8 is abutted against the base main material angle steel 1 by rotating the outer bolt 7, at this time the clamping plate 8 fixes the angle shaft 5 through the outer bolt 7, and at this time the ruler 9 corresponds to a scale value on the angle plate 6 under the action of gravity. When the base main material angle steel 1 inclines, the clamping plate 8 drives the angle shaft 5 to rotate, and the scale value corresponding to the ruler 9 on the angle plate 6 changes. The clamping plate 8 is abutted against the base main material angle steel 1 by rotating the outer bolt 7, which can simply and quickly fix the angle shaft 5, without the need for complex tools or equipment, and can also adapt to base main material angle steels 1 of different sizes and shapes. Through the scale on the angle plate 6, the reading of the inclination angle becomes intuitive and accurate, which is convenient for the on-site construction personnel and maintenance personnel to quickly judge the inclination of the base main material angle steel 1, and also provides accurate reference data for subsequent adjustment or repair work. The angle plate 6 can be placed inside the base main material angle steel 1, the angle plate 6 is placed inside the base main material angle steel 1, and the base main material angle steel 1 itself is used as a shield, which effectively prevents the influence of wind on the ruler 9, and ensures the stability and reliability of the inclination warning device 4 in harsh weather conditions.

[0026] As Figure 4As shown, the side wall of the angle plate 6 is fixed with several limiting plates 10, the limiting plates 10 correspond to the scale on the angle plate 6, the end of the ruler 9 away from the angle shaft 5 is fixed with a signal bin 11, the signal bin 11 is hinged with a signal rod 12 through a torsion spring, the signal rod 12 can abut against the limiting plate 10, the ruler 9 is connected with the angle shaft 5 through a rotation damper 13. The angle value corresponding to the limiting plate 10 is the maximum inclination range that the tower can withstand. The signal bin 11 is provided with a trigger device such as a micro switch, the micro switch is used to detect the deviation and inclination of the signal rod 12, and the signal bin 11 is provided with a signal transmitting device and a battery, the signal rod 12 deviation signal can be transmitted to the host, and a delay device is arranged on the trigger device or the duration of the signal received by the host is used to judge whether it is caused by external force, such as the signal rod 12 is inclined for a certain time to make the signal transmitting device transmit the signal to the host, which effectively avoids the false alarm caused by temporary external force interference such as wind blowing and small animal touching, and reduces unnecessary maintenance cost and personnel trouble. The trigger device, signal transmitting device and battery are all prior art. The signal bin 11 integrates the signal transmitting device and the battery, which can work independently without external power supply, and is convenient for remote monitoring.

[0027] When the tower inclines, the limiting plate 10 will deviate relative to the signal rod 12, when the limiting plate 10 abuts against the signal rod 12, and the limiting plate 10 makes the signal rod 12 rotate, the signal bin 11 sends the signal of tower inclination, and notifies the staff to reinforce the tower. When the staff reinforces and maintains the tower, the limiting plate 10 is reset under the driving of the angle plate 6, the signal rod 12 is reset under the action of the torsion spring, the ruler 9 can not easily rotate under the wind force or time through the rotation damper 13, which ensures the accuracy of the data, and the signal bin 11 can also be used as a counterweight of the ruler 9, which further enhances the stability of the ruler 9 and prevents shaking and false alarm caused by external force. Through the accurate correspondence of the limiting plate 10 and the scale on the angle plate 6, and the interaction of the signal rod 12 and the limiting plate 10, the inclination range of the tower foundation main material angle steel 1 is accurately monitored, when the inclination exceeds the preset safety range, the signal can be triggered immediately, which improves the accuracy and timeliness of the monitoring.

[0028] As Figure 2 , 4As shown, the angle shaft 5 is screwed with an inner bolt 14 on the inner side wall of the base main material angle steel 1, and the inner bolt 14 can be abutted with the inner side wall of the base main material angle steel 1 away from the end of the angle shaft 5 through a pressing plate 15. The inner bolt 14 and the pressing plate 15 provide an acting force opposite to the clamping plate 8, and fix the angle shaft 5 from the other end of the base main material angle steel 1. The bidirectional fixing mode significantly enhances the overall stability of the angle shaft 5, reduces displacement or rotation caused by external force, and is suitable for base main material angle steels 1 of different sizes and models, and has strong universality and adaptability. By arranging the clamping plate 8 and the pressing plate 15 at both ends of the base main material angle steel 1, the stress of the base main material angle steel 1 in the length direction can be more uniform, and the problem of bending of the angle shaft 5 caused by uneven stress can be avoided.

[0029] The inclination warning device 4 is 0.5-1.5m away from the horizon. By setting the height of the inclination warning device 4, the direct influence of natural factors such as wind and rain on the ruler 9 can be effectively reduced, so as to avoid the shaking of the ruler 9 and the deviation of the measured angle caused by wind, so that the monitoring result is more reliable, and the lower position is convenient for inspection and maintenance, reduces the demand for high-altitude operation, and reduces the installation risk.

[0030] The base main material angle steel 1 is connected with the connecting angle steel 3 and the supporting angle steel 2 through the fixing bolt.
