Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a warning device for electric power construction engineering construction. Background Art

[0002] Power construction is very common in our lives. We can also see power construction on ordinary roads. At the same time, power construction is also going on in some uncommon places. During power construction, warning devices are needed to warn pedestrians.

[0003] In the prior art, a Chinese utility model patent document with a publication number of CN217104799U provides a warning device for construction of electric power construction projects. The utility model installs the warning device on the ground at the electric power construction site through a base, and then rotates the supporting diagonal rod to insert the end of the supporting diagonal rod into the ground. The warning plate is supported by the supporting diagonal rod. When the warning plate is collided, the warning plate will squeeze the supporting diagonal rod, thereby causing the telescopic spring between the first support rod and the second support rod to contract, and the positioning rod extends inside the telescopic cavity. The telescopic spring consumes the external force on the warning plate, which plays a shock-absorbing role, prevents the warning plate from being damaged after a collision, and improves the service life of the warning plate.

[0004] However, this solution has the following shortcomings: in actual situations, when the device is hit, it is impossible to determine whether the impact position is on the column or on the warning plate; secondly, when the warning plate is hit, it is also impossible to determine the impact position of the warning plate. When the warning plate is hit non-frontally, the shock absorption effect of its diagonal support rod will be significantly reduced, making the shock absorption effect of the device average and poor in practicality. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the solutions in the background technology have the problems of general shock absorption performance and poor practicality. In view of the defects of the prior art, a warning device for construction of electric power engineering is provided.

[0006] The utility model solves the technical problem by adopting the following technical solution: comprising a base, a column is arranged on the top of the base, a warning plate is arranged on the top of the column, and the column is a spring.

[0007] Furthermore, the column is a tension spring.

[0008] Furthermore, the base is provided with pins.

[0009] Furthermore, a shock-absorbing sleeve is provided on the outer side of the warning plate.

[0010] Furthermore, a protective shell is arranged between the warning plate and the shock-absorbing sleeve, and the top of the column is connected to the bottom of the protective shell.

[0011] Furthermore, a straight bevel coil spring is arranged between the protective shell and the shock absorbing sleeve, and the axial direction of the straight bevel coil spring is parallel to the edge of the warning plate.

[0012] Furthermore, the base and the column are magnetically connected.

[0013] Furthermore, a first permanent magnet is disposed on the top of the base, and a second permanent magnet is disposed on the bottom of the column, and the first permanent magnet is attracted to the second permanent magnet.

[0014] Furthermore, the magnetic force between the first permanent magnet and the second permanent magnet is smaller than the ultimate pulling force of the column.

[0015] The utility model discloses a warning device for electric power construction engineering construction, which has the following beneficial effects:

[0016] When in use, the warning device is installed on the bottom surface of the power construction site through the base. When the column or the warning plate is hit, the warning plate drives the column to swing away from the impact position, thereby avoiding a rigid collision between the device and the impact object, reducing the vibration caused by the collision, playing a shock-absorbing role, and preventing the device from being damaged after the collision. Compared with the existing technology, the structure is simpler, and the columns and warning plates protruding from the ground can play a better shock-absorbing role no matter where they are hit, and are more practical.

[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 As shown, a warning device for electric power construction engineering construction includes a base 1, a column 2 is arranged on the top of the base 1, a warning plate 3 is arranged on the top of the column 2, and the column 2 is a spring.

[0025] A spring is used as the column 2, and the spring has good elastic deformation performance in both axial and radial directions, so that when the column 2 itself and various positions of the warning plate 3 are hit, a good shock absorption effect can be maintained.

[0026] Column 2 is a tension spring.

[0027] Compared with compression springs, tension springs have better axial tensile elastic deformation performance, so when the device is hit, in addition to bending elastic deformation in the radial direction, it can also simultaneously produce axial tensile micro-deformation to relieve the impact force and return to its original state after the impact.

[0028] The base 1 is provided with pins 7 .

[0029] The base 1 is fixed on the ground at the power construction site by means of the pins 7. Of course, the base 1 can also be buried underground to fix the device.

[0030] A shock-absorbing sleeve 6 is arranged on the outer side of the warning plate 3 .

[0031] The shock-absorbing sleeve 6 can be made of a rubber ring and wrapped around the outer side of the warning plate 3 , mainly used to prevent the warning plate 3 from being dented or deformed due to local knocks and collisions.

[0032] A protective shell 9 is arranged between the warning plate 3 and the shock-absorbing sleeve 6 , and the top of the column 2 is connected to the bottom of the protective shell 9 .

[0033] The protective shell 9 is a rigid structure, such as a metal shell, which is used to avoid direct contact between the shock-absorbing sleeve 6 and the warning plate 3 and reduce wear between the warning plate 3 and the shock-absorbing sleeve 6 .

[0034] A straight bevel coil spring 8 is arranged between the protective shell 9 and the shock absorbing sleeve 6 , and the axial direction of the straight bevel coil spring 8 is parallel to the edge of the warning plate 3 .

[0035] Compared with the linear positive coil spring, when the linear helical coil spring 8 is impacted by external force in the radial direction, the radial elastic deformation performance of the linear positive coil spring is weaker and it is prone to plastic deformation. The body of the linear helical coil spring 8 can undergo elastic deformation in the direction in which it is tilted to achieve a shock absorbing effect.

[0036] The base 1 and the column 2 are connected magnetically.

[0037] The magnetic connection between the base 1 and the column 2 is more convenient to disassemble than using other connecting parts (such as bolts) or other connection methods (such as welding).

[0038] A first permanent magnet 4 is disposed on the top of the base 1 , and a second permanent magnet 5 is disposed on the bottom of the column 2 . The first permanent magnet 4 and the second permanent magnet 5 are attracted to each other.

[0039] The first permanent magnet 4 and the second permanent magnet 5 can be made of strong magnets, which are easy to obtain and manufacture.

[0040] The magnetic force between the first permanent magnet 4 and the second permanent magnet 5 is smaller than the ultimate pulling force of the column 2 .

[0041] When the external impact force on the column 2 or the warning plate 3 is greater than the elastic limit of the column 2, the magnetic force between the first permanent magnet 4 and the second permanent magnet 5 is less than the ultimate pulling force of the column 2, so that the column 2 drives the second permanent magnet 5 to separate from the first permanent magnet 4, thereby avoiding plastic deformation caused by the external force on the column 2 being greater than its own elastic limit. When the column 2, the warning plate 3 and the second permanent magnet 5 fall off, the second permanent magnet 5 can be directly attracted to the first permanent magnet 4 during subsequent maintenance, which is convenient for maintenance;

[0042] At the same time, when the warning plate 3 falls, the shock-absorbing sleeve 6 and the linear bevel coil spring 8 can effectively protect the warning plate 3 from being damaged.

[0043] At the same time, a rope can be connected between the base 1 and the column 2. When the first permanent magnet 4 and the second permanent magnet 5 are separated, the rope is used to hold the column 2 to prevent the column 2 and the warning plate 3 from flying out to a position far away from the base 1 due to impact, and can also prevent loss.

[0044] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
