The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

The application is described below with reference to specific embodiments in conjunction with the following drawings:

example one

As shown in fig. 1 to 5, a detection alarm device provided in an embodiment of the present invention includes: a frame body 1; the connecting piece 2 is connected with the frame body 1, and the connecting piece 2 has a degree of freedom of swinging along the detection direction; the transceiver 3 is connected with the swinging end of the connecting piece 2, the input end 31 of the transceiver 3 is arranged at two sides of the output end 32 of the transceiver 3 along the swinging direction of the connecting piece 2, and the transceiver 3 is electrically connected with a first alarm 71; the control switch 4 is arranged on the frame body 1, the control switch 4 is in disconnectable action connection with the connecting piece 2 at a first station, and the control switch 4 is electrically connected with the transceiver 3; and the reflecting device 5 is arranged on the frame body 1, and the reflecting device 5 and the transceiving device 3 are oppositely arranged.

Here, support body 1 is used for bearing each structure and components and parts on the detection alarm device, support body 1 can be placed on waiting to detect the platform, when the platform body takes place the slope, support body 1 can follow the slope of platform body to the feasible setting is in detection structure on the support body 1 detects. Actually, the frame body 1 is mainly composed of a frame composed of iron rust-proof square steel. The bottom of the frame body 1 is a hollow square tube.

The connecting piece 2 is used for connecting the transceiver 3 to the frame body 1, so that when the transceiver 3 is used, the transceiver 3 connected with the connecting piece 2 can swing along with the connecting piece 2 because the connecting piece 2 has the freedom degree of swinging along the detection direction.

The above-mentioned detection direction refers to the inclination direction detected for the platform, that is, as shown in fig. 2 and 3, when one end of the platform is inclined to the lower right and the other end is inclined to the upper left, the detection direction is the left-right direction, and the connecting member 2 swings in the left-right direction.

Here, the upper end of the connector 2 is rotatably connected to the frame body 1, and the lower end of the connector 2 is fixedly connected to the transceiver 3, and specifically, the shape of the connector 2 includes, but is not limited to, a regular plate shape, an irregular plate shape, or a strip shape. The connection mode between the connecting piece 2 and the frame body 1 includes, but is not limited to, a hinge structure, a bearing structure or a screw mechanism connection. The connection mode of the lower end of the connecting piece 2 and the transceiver 3 includes but is not limited to screw connection, welding and integral forming connection.

Therefore, when the platform is used, the connecting piece 2 and the transceiver 3 are always kept in a state of being always vertically arranged with the horizontal ground no matter whether the platform body or the frame body 1 is in an inclined state or not due to the influence of gravity on the connecting piece 2 and the transceiver 3.

The transceiver 3 cooperates with the reflection device 5 to form a detection alarm device, the transceiver 3 includes an output terminal 32 for emitting an optical electrical signal and an input terminal 31 for receiving an optical electrical signal emitted from the input terminal 31, and specifically, the transceiver 3 includes but is not limited to an optical transceiver.

The control switch 4 is electrically connected with the transceiver 3, and the control switch 4 can be matched with the connecting piece 2 to control the using state of the transceiver 3. Here, when the platform body is stable, the control switch 4 turns off the transceiver 3, and when the platform body is in an inclined state, the control switch 4 turns on the transceiver 3 to operate.

Specifically, since the connector 2 can reflect whether the platform body is in an inclined state, the connector 2 and the control switch 4 are matched with each other to control the on/off of the transceiver 3. More specifically, when the platform body is kept in a horizontal state, the connecting piece 2 is operatively connected with the control switch 4, and when the platform body is inclined, the connecting piece 2 is disconnected from the control switch 4. Actually, when the platform body is kept in a horizontal state, the connecting piece 2 and the control switch 4 are arranged in a coplanar manner (i.e. the first station), an action end of the control switch 4 for controlling on and off is in action connection with the connecting piece 2, the control switch 4 is disconnected from the transceiver 3, when the platform body is inclined, the connecting piece 2 and the control switch 4 are mutually staggered, and the transceiver 3 is turned on by the control switch 4. The control switch 4 may be a touch key switch or an inductive switch, and preferably, the control switch 4 is a touch key switch, for example, a micro switch.

Therefore, by utilizing the pendulum bob principle of the connecting piece 2, the control scheme of opening and closing the control switch 4 according to the levelness state of the platform body is realized, and the problems of large power consumption and short service life caused by the fact that the detection device is in a normally open state under the normal work of the platform body of the loop are solved.

Further, when the lifting stroke of the platform is large, the equipment on the platform cannot be connected with a cable for power supply. In the embodiment of the invention, the on-off state of the transceiver 3 can be controlled by the connecting piece 2 and the control switch 4, so that power can be supplied by additionally arranging the battery pack 8, and the embodiment of the invention can be used for a platform body with a larger lifting stroke, thereby reducing the maintenance frequency of workers and improving the working efficiency.

Further, in the embodiment of the present invention, a normally open contact switch may be disposed inside the transceiver device 3, when the input end 32 receives a signal sent by the input end 31 through the reflection device 5, the normally open contact switch is opened, the transceiver device 3 is connected to the first alarm 71, at this time, the first alarm 71 is in a non-operating state, when the input end 32 cannot receive the signal sent by the input end 31 through the reflection device 5, the normally open contact switch is in a closed state, the transceiver device 3 opens the first alarm 71, at this time, the first alarm 71 is in an operating state, and an alarm is given, more specifically, the transceiver device 3 and the first alarm 71 may be connected by a cable, an electric wire, or the like, and may also be connected wirelessly by a wireless receiving board, a mobile network, a WiFi, or the like.

The first alarm 71 includes, but is not limited to, a magnetic switch alarm, a vibration alarm, an acoustic alarm, an ultrasonic alarm, an electric field alarm, a microwave alarm, an infrared alarm, a laser alarm and a video motion alarm, and the staff can select the alarm according to the field use requirement.

The reflecting device 5 includes but is not limited to a mirror, the reflecting device 5 may be fixed or detachably fixed on the frame body 1, and the acting surfaces of the reflecting device 5 are respectively opposite to the end surface of the input end 31 and the end surface of the output end 32. That is, in use, when the input terminal 31 of the transceiver 3 can receive the photoelectric signal sent from the input terminal 31 through the reflection device 5, the transceiver 3 controls the switch of the first alarm 71 to be turned off, and when the input terminal 31 of the transceiver 3 cannot receive the photoelectric signal sent from the input terminal 31 through the reflection device 5, the transceiver 3 controls the switch of the first alarm 71 to be turned on to alarm.

Because thereby when the levelness that leads to whole loop platform body fluctuates that the swing of small amplitude may take place at controllable within range for the loop platform body, transceiver 3 with connecting piece 2 can swing for keeping with ground relative perpendicular, like this the light angle of the last output of output 32 of transceiver 3 probably changes thereby leads to input 31 probably can't receive the signal to cause the circumstances of wrong report alarm, it is consequently right the position and the size of output 32 and input 31 are adjusted.

Specifically, the input end 31 panel of the transceiver 3 is disposed on both sides of the output end 32 panel along the swinging direction of the connecting member 2, and more specifically, as shown in fig. 4, since the connecting member 2 drives the output end 32 panel to swing up and down relative to the reflection device 5, the swinging direction of the input end 31 panel and the connecting member 2 is disposed on both upper and lower sides of the output end 32 panel, where the input end 31 panel may be connected to the output end 32 panel or may not be connected to the output end 32. Preferably, the input end 31 may also be disposed around the output end 32. Thus, when the transceiver 3 swings, the input terminal 31 can receive the photoelectric signal reflected by the reflecting device 5.

Here, it should be noted that, when the positions and sizes of the output end 32 and the input end 31 and the size of the reflection area on the reflection device 5 are performed, a person skilled in the art may obtain the positions and sizes according to a limited number of experiments or may obtain the positions and sizes according to the calculation of the refraction angle, and therefore details are not described again.

Further, the embodiment of the present invention also discloses a detection method, which is applied to the detection alarm device in the embodiment of the present invention, and the method includes: when the connecting piece of the detection alarm device is positioned at a first station, the action end of the control switch of the detection alarm device is in action connection with the connecting piece, and the control switch is closed;

when the connecting piece is positioned at a second station, the action end of the control switch is staggered with the connecting piece, the control switch is turned on, and the output end of a transceiver on the detection alarm device is connected with the input end of the transceiver through a reflecting device;

Actually, as shown in fig. 1 to 3, the frame body 1 is a frame structure with a cubic shape, wherein the transceiver 3 is connected to the upper left cross frame in the frame body 1 through the connecting piece 2, the control switch 4 is arranged on the left front/rear frame rod in the frame body 1, the reflection device 5 is arranged on the right frame rod in the frame body 1 and is opposite to the transceiver 3, when the frame body 1 is in a horizontally stable state (i.e. as shown in fig. 1), the connecting piece 2 abuts against the contact of the control switch 4 (i.e. the first station), the control switch 4 is closed, and the transceiver 3 is closed; when the support body 1 is in the inclined state, the connecting piece 2 has two working states, the first one is: when the connecting piece 2 is staggered with the contact of the control switch 4, the transceiver 3 can still send and receive signals (namely, the second station) through the reflecting device 5 (namely, as shown in fig. 2), the control switch 4 is opened, the transceiver 3 can receive signals at the moment, and the first alarm 71 is closed, namely, the looper platform body is in a swinging state in a controllable range; the second method is as follows: connecting piece 2 with control switch 4's contact staggers mutually, transceiver 3 can't pass through when reflector 5 sends and received signal (promptly the third station) (as shown in fig. 3 promptly), control switch 4 opens, transceiver 3 opens, and transceiver 3 can received signal this moment, first alarm 71 is opened, shows promptly that the loop platform body is in uncontrollable slope, needs the staff to maintain.

Furthermore, in order to distinguish the two working states of the looping platform body more conveniently, the control switch 4 is connected with the second alarm 72. Specifically, the second alarm 72 includes, but is not limited to, a magnetic switch alarm, a vibration alarm, an acoustic alarm, an ultrasonic alarm, an electric field alarm, a microwave alarm, an infrared alarm, a laser alarm, and a video motion alarm, wherein in order to avoid confusion between the alarm signal of the looping platform body swinging in the controllable range and the alarm signal of the looping platform body in the severe inclined state, the worker may select an alarm different from the alarm signal of the first alarm 71 as needed. More specifically, the second alarm 72 may be disposed at any position within the loop platform body, outside the loop platform body, or within the frame body 1, for example, according to the use requirement. Preferably, the second alarm 72 is provided on the transceiver 3, and the second alarm 72 may be a laser alarm.

Example two

Further, in the embodiment of the present invention, as shown in fig. 1, 2, 3 and 9, a level 61 and a rack levelness adjusting device 62 are disposed on the rack 1.

Here, the detection alarm device needs to keep the connecting member 2 in an initial state, i.e. in a stable state, to be operatively connected to the control switch 4 when in use, and in actual use, the surface of the loop platform body may have an uneven problem, thereby causing the detection alarm device to be in an inclined position in the initial state. Therefore, in order to ensure the levelness of the frame body 1 in the initial state when in use, the connecting piece 2 can be connected with the detection switch in an action mode at the initial position on the loop platform body, and the loop platform body can be accurately measured.

More specifically, the adjusting bolt is a magnetic adjusting bolt, so that the rack body 1 can be stably fixed on the detection platform.

Because the surface area of the loop platform body is large, when detection is carried out, the traditional horizontal detection instrument is generally small, so that the detection result is inaccurate and observation is inconvenient, and therefore, the frame body 1 is adjusted into a telescopic frame body 1 structure in the embodiment of the invention, so that the loop platform body is suitable for loop platform bodies with different lengths. Specifically, the frame body 1 comprises a first frame body 11 and a second frame body 12, and the first frame body 11 and the second frame body 12 are connected through a telescopic structure. More specifically, a first sleeve is disposed at the bottom of the first frame 11, and a second sleeve is disposed at the bottom of the second frame 12, wherein the first sleeve and the second sleeve are sleeved. Therefore, when the telescopic pipe is used, the length of the sleeve can be adjusted according to needs, and after the adjustment is finished, the telescopic pipe can be fixed through the fastening device 13, and specifically, the fastening device 13 can be a bolt connected between the first sleeve and the second sleeve. In use, the two sleeves may be secured together by the action of one or more bolts. This fulfills the need to measure different size platforms.

In addition, as for the problem that the height difference between the first sleeve and the second sleeve may be generated, so that the whole rack 1 may be inclined when being placed, the measurement and adjustment may be performed by the level 61 and the rack levelness adjusting device 62 in the embodiment of the present invention.
