[0027] In order to enable personnel in the technical field to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
[0028] The embodiment of the present application provides a temporary reinforcing device for an electric pole, which can solve the problems of high cost of reinforcing and protecting the electric pole and inability to temporarily reinforce the electric pole in the related art.
[0029] As shown in Figure 1 the embodiment, the temporary reinforcing device for the electric pole comprises two half-barrel bodies 1, and the two half-barrel bodies 1 are connected to form a cavity 11 surrounding the electric pole.
[0030] As shown in Figure 2 each inner wall of the half-barrel body 1 is provided with a containing cavity closed by a sealing plate 2, an upper end surface of each half-barrel body 1 is provided with at least one water injection hole 14 in communication with the containing cavity, and a water-absorbing material 3 is arranged in the containing cavity.
[0031] In this embodiment, two semi-buckets are connected to form a cavity surrounding the utility pole. Each semi-bucket has an inner wall with a receiving cavity sealed by a sealing plate. Each semi-bucket has a water injection hole on its upper surface that communicates with the receiving cavity. The receiving cavity is filled with absorbent material. When temporary reinforcement of the utility pole is required, the two semi-buckets are wrapped around the utility pole and connected and fixed. Water is injected into the receiving cavity through the water injection hole by manual water injection. The water absorption properties of the absorbent material greatly increase the weight of the device, thereby achieving the function of temporarily reinforcing the utility pole and other power devices.
[0032] In this embodiment, when the pole does not require temporary reinforcement, the water-absorbing resin pack can be dehydrated and the device can be recycled, which is not only inexpensive but also recyclable.
[0033] Based on the above embodiments, in this embodiment, the above-mentioned accommodating cavity is divided into multiple small cavities 12 by multiple partitions 13, and the partitions 13 of adjacent small cavities 12 are provided with water passage holes; each small cavity 12 is provided with water-absorbing material 3.
[0034] Optionally, the water passage holes on the aforementioned partition 13 can be positioned close to the adjacent partition 13 to facilitate water permeability.
[0035] Optionally, the partition 13 is provided with multiple water passage holes to improve water permeability.
[0036] Alternatively, the aforementioned partition 13 may also be a mesh partition to improve water permeability.
[0037] Furthermore, in one embodiment, the water-absorbing material 3 is a water-absorbing resin package.
[0038] In this embodiment, the water-absorbing resin expands when it comes into contact with water, absorbing dozens of times its own volume of water, while also increasing its weight, thus effectively increasing the overall weight of the device.
[0039] like Figure 3 As shown, in one embodiment, each of the above-mentioned half-buckets 1 has at least one water outlet 15 communicating with the above-mentioned accommodating cavity on its lower end face.
[0040] Optionally, each of the above-mentioned half-buckets 1 has a plurality of water injection holes 14 communicating with the above-mentioned accommodating cavity on its upper end face, and each of the above-mentioned half-buckets 1 has a plurality of water outlet holes 15 communicating with the above-mentioned accommodating cavity on its lower end face, and the water injection holes 14 and the water outlet holes 15 are arranged in a one-to-one correspondence.
[0041] Optionally, the aforementioned accommodating cavity is divided into multiple small cavities 12 arranged in rows and columns by multiple partitions 13. Each row of small cavities 12 corresponds to a water inlet 14 and a water outlet 15.
[0042] In this embodiment, water injection is carried out using fire hydrants or rented water trucks through the water injection holes 14 opened on each half-bucket. When a large amount of water flows out of the water outlet 15, it indicates that the water-absorbing material has completed water absorption.
[0043] In other embodiments, each of the above-mentioned half-buckets 1 has a water injection hole 14 on its upper end face that communicates with the above-mentioned accommodating cavity, and each of the above-mentioned half-buckets 1 has a water outlet hole 15 on its lower end face that communicates with the above-mentioned accommodating cavity, and the water injection hole 14 and the water outlet hole 15 are respectively located on both sides of the half-bucket 1.
[0044] like Figure 4 As shown, in one embodiment, the sealing plate 2 is an arc-shaped plate adapted to the inner wall of the semi-barrel 1, and the sealing plate 2 is detachably connected to the semi-barrel 1.
[0045] In this embodiment, the sealing plate 2 is detachably connected to the above-mentioned half-bucket 1 to facilitate the removal, placement, and replacement of the absorbent material.
[0046] Furthermore, in one embodiment, both ends of the sealing plate 2 are provided with inserts 21, and the inner wall of the semi-barrel 1 is provided with slots 16 that are adapted to the inserts 21.
[0047] In this embodiment, the sealing plate 2 is detachable by the insertion strip 21 of the sealing plate 2 engaging with the slot 16 of the half-barrel 1.
[0048] Optionally, when the pole is a cylindrical pole, the two aforementioned semi-barrels 1 together form a cylindrical cavity; when the pole is a frustum-shaped pole, the two aforementioned semi-barrels 1 together form a frustum-shaped cavity.
[0049] like Figure 5 As shown, in this embodiment, the two semi-bucket bodies 1 and the sealing plate 2 can be made of high-molecular PE material, which has a certain degree of elasticity. When the two semi-bucket bodies 1 are closed to form a frustum-shaped cavity, the sealing plate 2 can be inserted from below the semi-bucket bodies 1 under the action of elastic force of tensile deformation until the cavity is closed.
[0050] Furthermore, in one embodiment, the two aforementioned half-barrels 1 are connected by a slider and a chute structure.
[0051] Preferably, each of the above-mentioned half-bucket 1 is provided with a dovetail groove 17 and a dovetail slider 18 at each end facing the other half-bucket 1, and the dovetail groove 17 of each of the above-mentioned half-bucket 1 is adapted to the dovetail slider 18 of the other half-bucket 1.
[0052] In this embodiment, the dovetail grooves 17 and dovetail sliders 18 of the two half-barrels 1 are connected in a cooperative manner, which can simultaneously meet the load-bearing requirements and the convenience of loading and unloading.
[0053] In other embodiments, the two half-barrels 1 can also be connected by a lap buckle arranged thereon.
[0054] Further, in an embodiment, the inner wall of the upper end of each half-barrel 1 is further provided with a pressure alarm mechanism.
[0055] Optionally, the pressure alarm mechanism can be a pressure sensor and a signal generator.
[0056] In the embodiment, the power supply of the pressure alarm mechanism can be introduced from the pole feeder terminal device, or a self-contained battery can be used. When the tension of the pole is greater than the designed tension, it will slowly deform and tilt, and the pressure will be transmitted to the pressure alarm mechanism. The pressure sensor detects the pressure from the pole, and then sends an alarm through the signal generator, which is sent to the central station. The staff can rush to the scene to carry out maintenance work such as deicing, thereby lengthening the interval of artificial inspection and reducing the workload.
[0057] In addition, in order to enhance the reinforcement effect, temporary reinforcement devices of different heights and thicknesses can also be customized according to the actual height of the pole.
[0058] The pole temporary reinforcement device of the embodiment increases the weight of the barrel body by adding small cavities in the half-barrel and filling the small cavities with water-absorbing resin bags, and reserving water holes between the small cavities, using the water-absorbing property of the water-absorbing resin, to play a role in reinforcing the pole body. Before the arrival of severe weather, installation is carried out in advance on the pole; when in use, water can be manually poured to reinforce the pole, not only realizing temporary reinforcement of the built power device, but also relatively low in cost and recyclable, reducing investment and protecting built power facilities or conducting pre-disaster control, while reducing the workload of staff in checking and patrolling the line and improving work efficiency.
