Description

Technical Field

[0001] The utility model relates to the field of building detection equipment, in particular to a warning device for building detection. Background Art

[0002] Building safety monitoring is particularly important during construction or in the later maintenance of buildings. If a building tilts, it means there is a high probability of safety hazards and the building structure is unstable. If things go on like this for a long time, serious safety accidents may occur. Therefore, regular or even real-time monitoring of the building's tilt is an important step to eliminate safety hazards.

[0003] There are various ways to detect the tilt of a building, from the traditional visual inspection by a worker holding a plumb line to the detection by a level meter, laser detection, etc. At present, the detection of the tilt of a building is basically done by instrument detection, which has a high degree of accuracy. For example, the Chinese utility model patent with the publication number CN218781790U discloses a building tilt warning device, which uses an infrared transmitter at the bottom of a gravity block suspended in a box, and an infrared sensor screen is set below, and the infrared sensor screen receives the position of the infrared emission to determine whether the ground is tilted.

[0004] The device has high accuracy and can accurately measure the tilt direction and angle of the ground. However, the safety hazards of buildings are not only reflected in the level of the ground. The device can only detect the level of the building's ground, but cannot detect the tilt of the wall, which has certain limitations. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a warning device for building detection, so as to solve the problem that the tilt warning device in the prior art has strong functional limitations and cannot detect the verticality of the wall. The specific technical solution is as follows:

[0006] A warning device for building monitoring, comprising a box, an alarm module is arranged on the box, an infrared receiver is arranged at the bottom of the inner side of the box, the infrared receiver is electrically connected to a controller, the controller controls the alarm module to work or stop, a counterweight block is suspended in the box, an infrared transmitter vertically downward is installed at the bottom of the counterweight block, when the bottom of the box is in a horizontal state, the infrared transmitter is located directly above the infrared receiver;

[0007] A laser line projector emitting in the horizontal direction is also installed on one side of the counterweight block. The laser line projector is used to project a vertical laser beam. A projection hole is opened on the corresponding side of the box body for the laser beam to pass through.

[0008] As a preferred embodiment: a horizontal first connecting shaft is further provided in the box body, a mounting block is provided outside the first connecting shaft, and the mounting block can rotate around the axis where the first connecting shaft is located;

[0010] The first connecting axis and the second connecting axis are perpendicular to each other.

[0011] As a preferred embodiment: at least four screw foot pads for adjusting the height are arranged at the bottom of the box.

[0012] As a preferred implementation manner: an openable sealing member is installed at the projection hole.

[0013] As a preferred implementation manner: the cross section of the projection hole is a vertical strip.

[0014] As a preferred implementation manner: the alarm module includes a buzzer and / or an indicator light.

DETAILED DESCRIPTION

[0024] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0025] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0026] Example

[0027] Combination Figure 1 As shown, a warning device for building monitoring has a box body 1 on the outside and at least four screw feet 12 on the bottom of the box body, which can be used to adjust the flatness of the bottom of the box body 1. The bottom of the box body 1 can also be adjusted to a nearly horizontal angle on some ground with a high inclination, so as to facilitate the use of the laser projector 6. A maintenance window 14 is provided on the box body 1 to facilitate the staff to repair and replace the equipment.

[0028] Recombination Figure 2As shown, a battery box 15 is provided in the box body 1 for supplying power to the electronic components, a horizontally arranged first connecting shaft 7 is installed on the top of the inner side of the box body 1, a mounting block 8 is provided outside the first connecting shaft 7, and the mounting block 8 can rotate around the axis where the first connecting shaft 7 is located. The first connecting shaft 7 can be a rotating shaft or a fixed shaft. When the first connecting shaft 7 is used as a rotating shaft, the mounting block 8 is fixedly connected to the first connecting shaft 7, and the first connecting shaft 7 is rotatably mounted on the inner wall of the box body 1; when the first connecting shaft 7 is used as a fixed shaft, the first connecting shaft 7 is fixedly mounted on the inner wall of the box body 1, and the mounting block 8 is rotatably sleeved on the outside of the first connecting shaft 7.

[0029] The mounting block 8 has a second connecting shaft 81 at the bottom. The second connecting shaft 81 is also horizontally arranged but perpendicular to the first connecting shaft 7. The counterweight block 4 is arranged outside the second connecting shaft 81 and can rotate along the axis of the second connecting shaft 81. The installation method of the second connecting shaft 81 is similar to that of the first connecting shaft 7, and can also be used as a fixed shaft or a rotating shaft, which will not be repeated here.

[0030] The counterweight block 4 includes an integral column portion 41 and a cone portion 42. The cone portion 42 is installed at the bottom of the column portion 41. The cone portion 42 is conical in shape, and the diameter gradually decreases from top to bottom. In some other embodiments, a pyramid shape may also be adopted. The main purpose is to make the center of gravity of the entire counterweight block 4 located in an upper position so that the bottom is not easily shaken by force. An infrared transmitter 5 is provided at the bottom of the cone portion 42 and is arranged vertically downward. Correspondingly, an infrared receiver 3 is provided on the inner floor of the box body 1 at a position directly below the infrared transmitter 5. When the bottom of the box body 1 is in a horizontal state, the infrared receiver 3 can accurately receive the light emitted by the infrared transmitter 5, thereby transmitting the signal to the controller; when the bottom of the box body 1 is tilted, the infrared receiver 3 follows the tilt, but the infrared transmitter 5 is suspended and always remains in a vertical state due to the action of gravity. Therefore, the infrared receiver 3 cannot accurately receive the light emitted by the infrared transmitter 5 and send the signal to the controller. The controller controls the alarm module 2 to alarm and remind the construction personnel that the ground is tilted. The alarm module 2 is a buzzer or an indicator light or a combination of the two.

[0031] The column part 41 on the counterweight 4 is a polygonal column, and its cross section is a regular polygon, such as a quadrangular column, a hexagonal column, an octagonal column, etc. Figure 2 In the embodiment, a rectangular column 41 is used, which is convenient for installing equipment thereon while ensuring balance. A laser line projector 6 is installed on one side of the column 41, and a balance block 9 is provided on the corresponding surface of the other side opposite thereto. The laser line projector 6 and the balance block 9 have the same weight, thereby ensuring that the center of gravity of the counterweight 4 is not affected. Preferably, the balance block 9 can be a lighting lamp. When the staff inspects and replaces parts inside the box 1, the lighting lamp is turned on to facilitate the staff's inspection and operation.

[0032] exist Figure 2 In the figure, a projection hole 11 is provided at a corresponding position of the side wall of the box 1 opposite to the laser line projector 6. The projection hole 11 is preferably a vertical strip, which matches the vertical laser beam, and ensures that the area of ​​the projection hole 11 is minimized without affecting the projection of the laser line projector 6, so as to prevent the counterweight 4 from being disturbed by the external environment and air flow. Therefore, another function of the screw foot pads 12 at the bottom of the box 1 is that when the ground is in an inclined state, if the box 1 is not adjusted to a horizontal state, although the laser line projector 6 will still project a horizontal laser beam, because the box 1 is inclined, the projection hole 11 is also in an inclined state, which may cause a certain degree of obstruction to the projected laser beam, affecting the operation of the laser line projector 6. When there is no need to check the verticality of the wall, the outside of the projection hole 11 is sealed by a seal 13. In this embodiment, the seal 13 is fixed to the outside of the box 1 by screws.

[0033] The utility model adds the function of wall verticality detection to the traditional ground level detection device. One of the biggest advantages is that it utilizes the original counterweight block 4 in the level detection device and installs the laser line projector 6 on its side, so there is no need to do level adjustment. The laser line projector 6 always projects the light beam in the horizontal direction. In addition, the counterweight block 4 is indirectly installed inside the box body 1 through two horizontal and mutually perpendicular first connecting shafts 7 and second connecting shafts 81. On the one hand, when detecting the ground level, as long as the ground is tilted, no matter what the tilt direction of the ground is, at least one of the two rotating shafts will rotate to ensure that the infrared transmitter 5 is always facing the vertical direction; on the other hand, the counterweight block 4 is not suspended by a point, so the counterweight block 4 will not rotate, and the projection direction of the laser line projector 6 is always toward the projection hole 11, ensuring that the laser line projector 6 can work normally.

[0034] The detection method of wall verticality is:

[0035] Turn on the laser line projector 6 and make it project a vertical laser beam in the horizontal direction. Then rotate and adjust the angle of the box 1 in the horizontal direction so that the projected laser beam is projected obliquely onto the wall to be measured (that is, the laser line projector 6 is not facing the wall to be measured). At this time, if the wall to be measured is vertical, the laser beam projected by the laser line projector is also equivalent to a plane, which is perpendicular to the wall to be measured. Therefore, the laser beam projected on the wall to be measured is a vertical line, representing that the wall to be measured is vertical; if the wall is tilted forward or backward, the laser beam plane projected by the laser beam is no longer perpendicular to the wall, and the distance between the vertical laser beam and the inclined wall is different from top to bottom. Therefore, the laser beam projected on the inclined wall will form an inclined line, and the angle of the wall's forward or backward inclination can be measured from the inclination direction and angle.

[0037] In the present invention, unless otherwise clearly specified and limited, the first feature "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. "Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The above is only for explaining the implementation mode of the utility model and is not used to limit the utility model.
