Description

Technical Field

[0001] The utility model relates to the technical field of total stations, in particular to an automatic monitoring and protection device for total stations. Background Art

[0002] The total station automated monitoring system is an indispensable technical solution for engineering safety monitoring. The system consists of prisms arranged on the measured points based on the total station measurement. It can monitor the horizontal and vertical displacements of buildings in real time, thereby reflecting the overall deformation of the project. It can remotely transmit the collected data to the cloud platform through the wireless transmission module for data analysis and real-time display. Due to its advantages of high precision, no artificial errors, and high frequency, this technical system is increasingly used in engineering safety monitoring.

Although the existing total stations have certain protection capabilities, they have not yet met the requirements for long-term outdoor use, especially at construction sites. When rainwater accumulates on the lens of the total station on rainy days, it will significantly affect the accuracy of laser measurement and easily cause damage to the total station.

[0026] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model total station automatic monitoring and protection device is shown. In this embodiment, the total station automatic monitoring and protection device includes an installation box 1, two sets of door panels 2, sensors 3, two sets of door panel opening and closing mechanisms 4, and support columns 5 for supporting the installation box 1. The installation box 1 is provided with two sets of openings 11 arranged opposite to each other, and the openings 11, the door panels 2, and the door panel opening and closing mechanisms 4 correspond to each other; the door panels 2 are movably connected to the installation box 1, and are used to open or block the corresponding openings 11; the sensor 3 is arranged at the top of the outer wall of the installation box 1 and is connected to the door panel opening and closing mechanism 4, and the sensor 3 is used to collect the sensing signal in real time and send the sensing signal to the door panel opening and closing mechanism 4; the door panel opening and closing mechanism 4 is arranged at the top of the installation box 1 and is connected to the corresponding door panel 2, and the door panel opening and closing mechanism 4 is used to control the switch state of the corresponding door panel 2 according to the sensing signal, so as to open or block the corresponding opening 11 of the installation box 1.

[0028] Correspondingly, a plurality of groups of openings 11, door panels 2 and door panel opening and closing mechanisms 4 can be provided according to actual conditions, which provides high flexibility.

[0029] It should be noted that the sensor 3 is preferably a capacitive sensor or a resistive sensor, but is not limited thereto and can be selected according to actual conditions.

[0030] When sensor 3 adopts a capacitive sensor, the capacitive sensor uses the exposed copper trace on the sensing pad as a variable resistor, and its resistance value changes according to the amount of water on the surface; more water means better conductivity, resulting in lower resistance, thereby generating an output voltage corresponding to the amount of rain; therefore, tiny changes in water drops can be detected by the capacitive sensor, thereby triggering the sensor to send a signal.

[0031] When sensor 3 adopts a resistive sensor, the resistive sensor also uses the change of resistance on the sensing pad to detect rain; water drops falling on the sensing pad will reduce the resistance, thereby triggering the sensor to send a signal.

[0032] For example, when the weather changes from sunny to rainy, rain drops onto the sensor 3, and the electrical signal output by the sensor 3 changes from a high level to a low level (or from a low level to a high level). After receiving the low level signal (or high level signal), the door panel opening and closing mechanism 4 closes the door panel 2, so that the door panel 2 covers the opening 11 corresponding to the installation box 1.

[0033] like Figure 4, Figure 5 , Figure 6 and Figure 7 As shown, the door panel opening and closing mechanism 4 includes a driving motor 41 arranged on the inner side of the top wall of the installation box 1, a driving wheel 42 and a driven wheel 43 arranged on the outer side of the top wall of the installation box 1, a synchronous belt 44, a first synchronous member 45, a second synchronous member 46, a first hinge plate 47 and a second hinge plate 48; the driving wheel 42 and the driven wheel 43 are connected by a synchronous belt 44, and the first synchronous member 45 and the second synchronous member 46 are arranged on the synchronous belt 44; one end of the first hinge plate 47 is connected to the first synchronous member 45, and the other end of the first hinge plate 47 is connected to the opposite One end of the second hinged plate 48 is connected to the second synchronous member 46, and the other end of the second hinged plate 48 is connected to the other door leaf of the corresponding door panel 2; the power output shaft of the driving motor 41 passes through the top wall of the installation box 1 and is connected to the driving wheel 42 and drives the driving wheel 42, and the driving wheel 42 drives the driven wheel 43 through the synchronous belt 44, and the first synchronous member 45 and the second synchronous member 46 move synchronously with the synchronous belt 44 and drive the first hinged plate 47 and the second hinged plate 48 to adjust the opening and closing state of the corresponding door panel 2.

[0034] It should be noted that the driving motor 41 only needs to drive the driving wheel 42 to operate the entire door panel opening and closing mechanism 4, which saves space and reduces energy consumption. At the same time, driven by the driving motor 41, all components (driving wheel 42, driven wheel 43, synchronous belt 44, first synchronous member 45, second synchronous member 46, first hinge plate 47 and second hinge plate 48, etc.) operate synchronously without delay or jamming, thereby ensuring the smooth operation of the entire door panel opening and closing mechanism 4.

[0035] like Figure 5 As shown, the first synchronous member 45 and the second synchronous member 46 are respectively arranged on two different sides of the loop formed by the synchronous belt 44, so when the synchronous belt moves, the movement directions of the first synchronous member 45 and the second synchronous member 46 are opposite. Since the door panels 2 controlled by the first synchronous member 45 and the second synchronous member 46 have different opening and closing directions, they need to move in opposite directions to open or close the two sets of door panels 2 at the same time. In addition, the speeds of the two moving in opposite directions are the same, which can ensure the synchronization of the door panels 2 when opening and closing, so that the opening and closing process is more beautiful.

[0036] When working, the sensor 3 will send out corresponding electrical signals when it detects rain or when the rain stops. After the drive motor 41 receives different electrical signals, the power output shaft starts to rotate to drive the driving wheel 42; at the same time, the synchronous belt 44 also starts to rotate with it, and the first synchronous member 45 and the second synchronous member 46 realize the control of the opening and closing of the door panel 2. Among them, when the synchronous belt 44 rotates counterclockwise, the first synchronous member 45 and the second synchronous member 46 approach each other, and the door panel 2 is closed; when the synchronous belt 44 rotates clockwise, the first synchronous member 45 and the second synchronous member 46 move away from each other, and the door panel 2 is opened.

[0037] Furthermore, the door panel opening and closing mechanism 4 further includes a first movable hinge platform 49 (see Fig. 9 )、The first fixed hinge platform 410 (see Figure 5 )、The second movable articulated platform 411 (see Figure 5 ) and the second fixed hinge platform 412 (see Figure 5 ); One end of the first hinged plate 47 is connected to the first synchronous member 45 through the first movable hinge platform 49, and the other end is connected to a door leaf of the corresponding door panel 2 through the first fixed hinge platform 410; one end of the second hinged plate 48 is connected to the second synchronous member 46 through the second movable hinge platform 411, and the other end is connected to the other door leaf of the corresponding door panel 2 through the second fixed hinge platform 412.

[0038] like Figure 8 and Fig. 9 As shown, the first synchronous member 45 and the second synchronous member 46 both include a fixing member 413, an adapter block 414 and a locking block 415. The adapter block 414 and the locking block 415 are both provided with fixing holes. The fixing member 413 passes through the fixing holes to lock the locking block 415 and the adapter block 414 on the synchronous belt 44, so that the adapter block 414 moves synchronously with the synchronous belt 44. By providing fixing holes of corresponding sizes, the adapter block 414 and the locking block 415 can be quickly fixed on the synchronous belt 44, thereby improving the stability of the overall structure. At the same time, this structure is convenient for disassembly and replacement after the parts are aged.

[0039] Preferably, the door panel opening and closing mechanism 4 further includes a guide shaft 416 and a bearing seat 417 (see Figure 7 ), the two ends of the guide shaft 416 are fixed to the outer side of the top wall of the installation box 1 through the bearing seat 417, and the adapter block 414 is slidably installed on the two ends of the guide shaft 416.

[0040] It should be noted that the guide shaft 416 can be firmly fixed by the bearing seat 417 to keep it horizontal; in addition, since the adapter block 414 is restricted by the guide shaft 416, it will not slide out of the guide shaft 416.

[0041] More preferably, the top wall of the installation box 1 is further provided with at least two groups of baffles 418, the baffles 418 correspond one-to-one to the openings 11 and are arranged above the corresponding openings 11. By providing the baffles 418, the movement range of the door panel 2 can be effectively limited, thereby improving the stability of the equipment.

[0042] like Figure 6As shown, both ends of the baffle 418 are provided with strip grooves 419; one end of the first hinge plate 47 is connected to the first synchronous member 45, and the other end passes through a strip groove 419 to be connected to a door leaf of the corresponding door panel 2; one end of the second hinge plate 48 is connected to the second synchronous member 46, and the other end passes through another strip groove 419 to be connected to another door leaf of the corresponding door panel 2. Therefore, the first hinge plate 47 and the second hinge plate 48 are connected to the door panel 2 through the strip groove 419, which can effectively limit the movement range of the door panel 2 and prevent misalignment.

[0043] In summary, the working process of the utility model is as follows:

[0044] The sensor 3 will send out a corresponding electrical signal when it detects that it is raining or the rain has stopped; after receiving the changed electrical signal, the power output shaft of the driving motor 41 starts to rotate, and drives the driving wheel 42 to rotate, and the driven wheel 43 also starts to rotate following the driving wheel 42 through the synchronous belt 44. Driven by the synchronous belt 44, the first synchronous member 45 and the second synchronous member 46 move in opposite directions, and the first fixed hinge platform 410 and the second fixed hinge platform 412 also move with the synchronous members; because the first hinge plate 47 and the second hinge plate 48 are both movably connected to the fixed hinge platform by screws, when the first fixed hinge platform 410 and the second fixed hinge platform 412 move, the hinge plates will be driven to move; and the other ends of the first hinge plate 47 and the second hinge plate 48 are respectively connected to the first movable hinge platform 49 and the second movable hinge platform 411, and connected to the door panel 2, so when the first hinge plate 47 and the second hinge plate 48 move, the door panel 2 can be driven to move, thereby realizing the opening and closing of the door panel 2.

[0045] Therefore, the utility model can achieve: when it rains, the synchronous belt 44 rotates counterclockwise, the two adapter blocks 414 approach each other, and the door panel 2 is closed; when the rain stops, the synchronous belt 44 rotates clockwise, the two adapter blocks 414 move away from each other, and the door panel 2 opens.

[0046] Furthermore, a wireless communication module is provided on the sensor 3 or the door panel opening and closing mechanism 4; the wireless communication module can be used to receive signals from the mobile terminal. When the total station is urgently needed, the terminal signal can be sent through the wireless communication module to open the door panel 2 at any time, or when the door panel 2 needs to be closed, the terminal signal can be sent through the wireless communication module to close the door panel 2 at any time, thereby saving labor costs.

[0047] In addition, a power supply is also provided in the installation box 1, and the power supply is used to supply power to the sensor 3 and the door panel opening and closing mechanism 4, so as to ensure that the sensor 3 and the door panel opening and closing mechanism 4 can work continuously.

[0048] As can be seen from the above, the utility model introduces an installation box 1, a door panel 2, a sensor 3 and a door panel opening and closing mechanism 4 to form an automatic monitoring and protection device for a total station. The door panel 2 of the total station protection device can be closed in time when it rains and the door panel 2 of the total station protection device can be automatically opened after the rain stops, thereby realizing fully automatic operation and solving the problem that rainwater accumulates on the lens of the total station, which easily causes damage to the total station.

[0049] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
