Description

Technical Field

[0001] The present invention relates to the technical field of insulating shoe structures, and particularly to an insulating shoe that is easy to ventilate. Background Art

[0002] The maintenance of power equipment is the basis for the normal use of power equipment and an important guarantee for ensuring the safe and stable operation of power equipment. In places where high-voltage electrical equipment is concentrated, such as substations or converter stations, due to grounding, a diffused potential distribution area is usually formed on the ground. After maintenance personnel enter this area, a potential difference will be formed between the two feet of the maintenance personnel. If the potential difference exceeds the human safety voltage and the insulation performance of the insulating shoes decreases or fails, it may endanger the personal safety of the maintenance personnel.

[0003] In the hot summer, during the maintenance process at the power site, power workers will run back and forth at the power site, resulting in a relatively high temperature and strong odor inside the insulating shoes, seriously affecting the wearing comfort of power workers. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an insulating shoe that is easy to ventilate, so as to solve the problem that in the hot summer, the wearing comfort of power workers when wearing insulating shoes during maintenance work is poor in the prior art.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: An insulating shoe that is easy to ventilate, including a shoe body. A ventilation system is provided between the rear side of the sole of the shoe body and inside the shoe body. The ventilation system includes a ventilation adjustment groove opened at the bottom of the sole of the shoe body. A plurality of first ventilation holes communicating with the inside of the shoe body are opened at the bottom of the ventilation adjustment groove. A second ventilation hole is opened at the rear end of the sole of the shoe body. A ventilation adjustment block that passes through the notch of the ventilation adjustment groove and is placed under the sole of the shoe body is slidably clamped in the ventilation adjustment groove. A plurality of return springs are connected between the end of the ventilation adjustment block placed in the ventilation adjustment groove and the bottom of the ventilation adjustment groove. And a ventilation hole that connects the second ventilation hole and the plurality of first ventilation holes is opened at the end of the ventilation adjustment block that is slidably clamped in the ventilation adjustment groove. The ventilation hole is arranged along the sliding direction of the ventilation adjustment block. An elastic adjustable seal for sealing the ventilation hole is slidably arranged on the side close to the bottom of the ventilation adjustment groove in the ventilation hole. A limiting top rod structure is arranged on the inner wall of the ventilation adjustment groove between the bottom of the ventilation adjustment groove and the ventilation adjustment block;

[0006] During the movement of the ventilation adjustment block towards the bottom of the ventilation adjustment groove, the limiting top rod structure abuts against the elastic adjustable seal to make the elastic adjustable seal disengage from the sealing of the ventilation hole.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] After this insulating shoe is worn on the feet of power workers, when the worker steps on the ground, the part of the ventilation adjustment block that penetrates out of the ventilation adjustment groove moves into the ventilation adjustment groove, thereby sucking the external gas from the second ventilation hole into the air guide hole; after the ventilation adjustment block slides a certain distance in the ventilation adjustment groove, the limit ejector rod structure abuts against the elastic adjustable seal, causing the elastic adjustable seal to disengage from the sealing of the air guide hole, so that the air guide hole connects the plurality of first ventilation holes and the second ventilation hole. When the ventilation adjustment block continues to move in the ventilation adjustment groove, the fresh air introduced into the air guide hole is pressed into the shoe body from the plurality of first ventilation holes to cool and ventilate the shoe body; after this insulating shoe is separated from the ground contact, under the action of a plurality of return springs, the ventilation adjustment block slides in the reverse direction, and the elastic adjustable seal resets to seal the air guide hole again; during the continuous contact process between the insulating shoe and the ground by the power worker, the fresh air from the outside is continuously sucked into the shoe body for cooling and ventilation, greatly improving the comfort of the power worker wearing it.

[0013] The present invention will be further described in detail below through specific embodiments:

[0014] The reference numerals in the accompanying drawings of the specification include: shoe body 1, ventilation adjustment groove 2, first ventilation hole 3, second ventilation hole 4, ventilation adjustment block 5, return spring 6, air guide hole 7, sealing block 8, locking spring 9, limiting block 10, ejector rod 11, voltage inductor 12, clamping block 13, locking block 14, through hole 15, support spring 16, wire passing hole 17, wire winding rod 18, traction wire 19, horizontal section 41, inclined section 42, insulating protection plate 20.

[0015] Combined with Figure 1 、 Figure 2 and Figure 3, an embodiment of the present invention provides an insulating shoe that is easy to ventilate, including a shoe body 1. A ventilation system is provided between the rear side of the sole of the shoe body 1 and inside the shoe body 1. The ventilation system includes a ventilation adjustment groove 2 opened at the bottom of the sole of the shoe body 1. A plurality of first ventilation holes 3 communicating with the inside of the shoe body 1 are opened at the bottom of the ventilation adjustment groove 2. A second ventilation hole 4 is opened at the rear end of the sole of the shoe body 1. A ventilation adjustment block 5 that passes through the notch of the ventilation adjustment groove 2 and is placed under the sole of the shoe body 1 is slidably clamped in the ventilation adjustment groove 2. A plurality of return springs 6 are connected between the end of the ventilation adjustment block 5 placed in the ventilation adjustment groove 2 and the bottom of the ventilation adjustment groove 2. And an air guide hole 7 that communicates the second ventilation hole 4 with the plurality of first ventilation holes 3 is opened at the end of the ventilation adjustment block 5 that is slidably clamped in the ventilation adjustment groove 2. The air guide hole 7 is arranged along the sliding direction of the ventilation adjustment block 5. An elastic adjustable seal member for sealing the air guide hole 7 is slidably arranged on the side of the air guide hole 7 close to the bottom of the ventilation adjustment groove 2. A limit ejector rod structure is arranged on the inner wall of the ventilation adjustment groove 2 between the bottom of the ventilation adjustment groove 2 and the ventilation adjustment block 5; when the ventilation adjustment block 5 moves into the bottom of the ventilation adjustment groove 2, the limit ejector rod structure abuts against the elastic adjustable seal member, causing the elastic adjustable seal member to disengage from the sealing of the air guide hole 7.

[0016] After this insulating shoe is worn on the feet of power workers, when the worker's foot steps on the ground, the part of the ventilation adjustment block 5 that passes through the ventilation adjustment groove 2 moves into the ventilation adjustment groove 2, thereby sucking the outside air from the second ventilation hole 4 into the air guide hole 7; after the ventilation adjustment block 5 slides a certain distance in the ventilation adjustment groove 2, the limit ejector rod structure abuts against the elastic adjustable seal member, causing the elastic adjustable seal member to disengage from the sealing of the air guide hole 7, so that the air guide hole 7 communicates the plurality of first ventilation holes 3 with the second ventilation hole 4. When the ventilation adjustment block 5 continues to move in the ventilation adjustment groove 2, the fresh air introduced into the air guide hole 7 is pressed into the shoe body 1 from the plurality of first ventilation holes 3 to cool and ventilate the inside of the shoe body 1; after this insulating shoe is separated from the ground contact, under the action of the plurality of return springs 6, the ventilation adjustment block 5 slides in the reverse direction, and the elastic adjustable seal member resets to seal the air guide hole 7 again; during the continuous contact process of the power worker with the ground, the fresh air outside is continuously sucked into the shoe body 1 for cooling and ventilation, greatly improving the comfort of the power worker when wearing.

[0017] Combined Figure 2 and Figure 3, According to another embodiment of the present invention, the insulating shoes that are easy to ventilate further include a stepped hole in which the air guide hole 7 is designed with a larger aperture in the middle section than at both ends. The elastic adjustable seal includes a sealing block 8 slidably disposed in the large-hole section of the stepped hole. The diameter of the sealing block 8 is larger than the aperture of the small-hole section of the stepped hole and smaller than the aperture of the large-hole section of the air guide hole 7. The sealing block 8 is in sealing contact with one end of the large-hole section of the air guide hole 7 close to the limit ejector rod structure, and a plurality of locking springs 9 are connected between the sealing block 8 and the inner wall of the large-hole section of the air guide hole 7; during the movement of the ventilation adjustment block 5 towards the bottom of the ventilation adjustment groove 2, the limit ejector rod structure abuts against the sealing block 8 to communicate the air guide hole 7.

[0018] When the ventilation adjustment block 5 moves into the ventilation adjustment groove 2, the limit ejector rod structure abuts against the sealing block 8 to cause the sealing block 8 to disengage from the seal of the end of the large-hole section of the air guide hole 7 close to the limit ejector rod structure, so that the sealing block 8 moves in the large-hole section of the air guide hole 7 in a direction away from the limit ejector rod structure. Through the design of the diameter of the sealing block 8, the aperture of the small-hole section of the stepped hole, and the aperture of the large-hole section of the air guide hole 7, the air guide hole 7 is communicated, and then the fresh air from the outside is drawn into the shoe body 1 through the channel formed by the second air vent 4, the air guide hole 7, and the plurality of first air vents 3 to cool and ventilate the inside of the shoe body 1; after the shoe body 1 is separated from the ground, the ventilation adjustment block 5 is reset under the elastic restoring force of the plurality of restoring springs 6, the limit ejector rod structure is disengaged from the sealing block 8, and the plurality of locking springs 9 are reset to make the sealing block 8 in sealing contact with one end of the large-hole section of the air guide hole 7 close to the limit ejector rod structure to disconnect the communication of the air guide hole 7.

[0019] Among them, the adopted limit ejector rod structure includes a limit block 10 connected to the inner wall of the ventilation adjustment groove 2 and an ejector rod 11 connected to the limit block 10. The free end of the ejector rod 11 penetrates into the air guide hole 7 and does not contact the sealing block 8.

[0020] During the movement of the ventilation adjustment block 5 into the ventilation adjustment groove 2, the ejector rod 11 abuts against the sealing block 8 to move the sealing block 8 and conduct the air guide hole 7; when the ventilation adjustment block 5 moves to abut against the limit block 10, the end of the ventilation adjustment block 5 close to the ground is flush with the bottom surface of the sole of the shoe body 1, and the ventilation adjustment block 5 no longer continues to move into the ventilation adjustment groove 2; the limit block 10 plays a limiting role and also protects the plurality of restoring springs 6.

[0021] As Figure 1 shown, according to another embodiment of the present invention, the insulating shoes that are easy to ventilate further include a structural optimization of the ventilation adjustment groove 2 and the ventilation adjustment block 5. The adopted ventilation adjustment groove 2 is a stepped groove with a larger cross-sectional area at the bottom than at its notch. The ventilation adjustment block 5 is a convex block. The large-head end of the convex block is slidably disposed in the stepped groove, and the air guide hole 7 is opened in the large-head end of the convex block.

[0022] The sliding engagement between the ventilation adjustment groove 2 and the ventilation adjustment block 5 is achieved through the specific structural refinement and connection and matching relationship between the ventilation adjustment groove 2 and the ventilation adjustment block 5 .

[0023] Combination Figure 2 and Figure 4 According to another embodiment of the present invention, the insulating shoe that is easy to ventilate further includes a voltage sensor 12 connected to the rear end of the shoe body 1 through a clamping structure, the clamping structure includes a clamping slot opened on the rear end of the shoe body 1 and a clamping block 13 connected to the voltage sensor 12, an adjustment hole connected to the middle part of the second ventilation hole 4 is opened on the bottom side wall of the clamping slot, a mounting slot is opened on the side wall of the clamping block 13, a locking block 14 is elastically connected in the mounting slot, and a conducting hole 15 is opened in the middle of the locking block 14; after the bottom of the clamping block 13 is embedded in the clamping slot, the locking block 14 passes through the rear part of the adjusting hole and penetrates into the second ventilation hole 4, the locking block 14 divides the second ventilation hole 4 into two independent sections, the conducting hole 15 is connected to the second ventilation hole 4 and the aperture of the conducting hole 15 is smaller than the aperture of the second ventilation hole 4.

[0024] Among them, the voltage sensor 12 is an existing electrical component. When the insulating shoe enters the electrical area, it can sound an alarm to remind the power workers; after the block 13 and the slot are assembled, the locking block 14 passes through the adjustment hole and partially penetrates into the second ventilation hole 4 to fix the block 13 in the slot, thereby achieving the purpose of fixing the voltage sensor 12 on the shoe body 1; at the same time, after the locking block 14 extends into the second ventilation hole 4, the second ventilation hole 4 continues to be in a conductive state through the conducting hole 15, and the aperture design of the conducting hole 15 and the second ventilation hole 4 cooperates with the locking block 14 to divide the second ventilation hole 4 into two independent sections so that the locking block 14 forms an annular cofferdam along the circumferential direction of the inner wall in the second ventilation hole 4, thereby preventing a small amount of gas that has penetrated into the second ventilation hole 4 along the inner wall of the second ventilation hole 4 from continuing to move toward the guide hole 7, so that the locking block 14 also plays a certain role in isolating liquid.

[0025] like Figure 4 As shown, according to another embodiment of the present invention, the insulating shoe that is easy to ventilate also includes a support spring 16 connected between the locking block 14 and the bottom of the mounting groove, and the block 13 is placed on the side wall outside the slot and has a threading hole 17 extending to the bottom of the mounting groove, the threading hole 17 is connected to the mounting groove, the block 13 is placed on the side wall outside the slot and is threadedly connected to a take-up rod 18, a traction wire 19 is passed through the threading hole 17, one end of the traction wire 19 is wrapped around the take-up rod 18 for multiple turns and then fixedly connected, and the other end is connected to the end of the locking block 14 close to the support spring 16.

[0026] When the winding rod 18 is rotated to wind the traction wire 19, the locking block 14 is moved towards the direction close to the clamping groove, so that the locking block 14 retracts into the clamping groove, and then the clamping block 13 can be removed from the clamping groove, and the voltage inductor 12 can be removed from the shoe body 1; after the clamping block 13 is embedded into the clamping groove again, the winding rod 18 is rotated in the reverse direction to unwind the traction wire 19, and the supporting spring 16 extends, so that the locking block 14 passes through the adjusting hole again and partially penetrates into the second air exchange hole 4, completing the installation of the voltage inductor 12.

[0027] As Figure 4 shown, according to another embodiment of the present invention, the insulating shoe easy to ventilate further includes that one end of the second air exchange hole 4 far away from the air guide hole 7 includes a horizontal section 41 and an inclined section 42 connected to the horizontal section 41. The horizontal section 41 is located between the inclined section 42 and the air guide hole 7, and the high end of the inclined section 42 is the end connected to the horizontal section 41, and the adjusting hole is communicated with the horizontal section 41.

[0028] Through the design of the positions and connection modes of the horizontal section 41 and the inclined section 42 of the second air exchange hole 4, the possibility of external liquid entering the second air exchange hole 4 is greatly reduced, making the usability of this insulating shoe better.

[0029] As Figure 1 shown, according to another embodiment of the present invention, the insulating shoe easy to ventilate further includes that the bottom of the sole of the shoe body 1 is designed into a serrated shape to improve its anti-slip ability, and an insulating protection plate 20 is embedded at the front end of the shoe surface of the shoe body 1 to improve the safety performance of the shoe body 1.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
