Description

Technical Field

[0001] The invention relates to the technical field of electric power installation and maintenance, and in particular to a temperature raising and lowering device for an insulating bucket of an insulating bucket arm vehicle. Background Art

[0002] Non-stop operation of 10kV distribution network is an important means to improve the reliability of distribution network power supply. The core tool for non-stop operation of 10kV distribution network is the insulated boom truck. The insulated boom truck is a special vehicle that performs intermediate potential operations in places with convenient transportation and complex wiring. At present, at the operation site, operators need to wear a full set of thick and airtight resin insulating clothing, insulating gloves and insulating boots, and stand in the insulating bucket to perform corresponding operations to achieve non-stop operation of 10kV distribution network. The working conditions are relatively difficult, especially in summer and winter. There is a phenomenon of heatstroke in summer and freezing in winter that is prone to occur after working for too long, which greatly affects the efficiency of non-stop operation.

[0003] Since the insulated boom truck does not stop during the operation at the work site, the insulated boom truck is equipped with an air conditioner to provide cold or hot air to the cab in time according to different working environments. In order to solve the above-mentioned problems encountered by workers in the insulated bucket during work and improve working efficiency, the present application proposes a temperature raising and lowering device for the insulated bucket of an insulated boom truck. Summary of the invention

[0004] In order to overcome the above-mentioned problems, the purpose of the present invention is to provide a temperature reduction and heating device for the insulated bucket of an insulated boom truck. The temperature reduction and heating device utilizes the continuous working requirement of the engine of the insulated boom truck during operation to output the hot air or cold air provided to the cab into the insulated bucket, thereby ensuring that the workers in the insulated bucket are in a comfortable state under the requirement of non-stop operation, solving the problems of heatstroke in high temperature in summer and freezing in low temperature in winter, achieving efficient operation, and rationally utilizing the resources during the operation of the insulated boom truck to save costs.

[0005] The technical solution adopted by the present invention is: it includes a switch-type double-nozzle valve, a first insulating hose, a rotating joint, a second insulating hose, and an air outlet. The switch-type double-nozzle valve is installed on the hot and cold air main duct outside the cab of an insulated boom truck. One end of the first insulating hose is connected to the output port of the switch-type double-nozzle valve. The first insulating hose is installed along the surface of the boom truck and fixed with a snap, and the other end is connected to one end of the rotating joint. The rotating joint is installed inside the turntable operating platform on the upper surface of the boom truck. The second insulating hose is installed inside the telescopic arm of the boom truck, and one end of it is connected to the other end of the rotating joint. The second insulating hose is laid along the hydraulic pipeline inside the telescopic arm, and the second insulating hose is fixed to the fixed frame inside the telescopic arm with a cable tie. The other end of the second insulating hose extends out of the connecting end of the telescopic arm to the air outlet, and the air outlet end of the air outlet is located inside the insulating bucket.

[0006] Furthermore, the switch-type double-nozzle valve includes a connecting pipe, a first switch, and a second switch. The connecting pipe is a T-shaped structure. The first switch is installed on the long side of the T-shaped structure, and the second switch is installed on the short side of the T-shaped structure. Both ends of the long side of the connecting pipe are connected to the cold and hot air main ducts, and the short side of the connecting pipe is connected to the first insulating hose.

[0007] Furthermore, the first insulating hose and the second insulating hose are made of steel wire reinforced polyurethane hose or steel wire reinforced nylon hose.

[0008] Furthermore, the diameter of the switch type double nozzle valve is 30-40 mm.

[0009] Furthermore, the connection between the first insulating hose and the switch-type double-nozzle valve and the rotating joint is fixed by a fixed clamp, and the connection between the second insulating hose and the rotating joint and the air outlet is fixed by a fixed clamp.

[0010] Furthermore, the rotating joint is a 360° rotatable movable joint.

[0011] Furthermore, the air outlet includes an air outlet duct, a left-right rotating plate, an up-down rotating plate, and an adjustment switch. The connecting end of the air outlet duct is a cylindrical structure, and its size is adapted to the diameter of the second insulating hose. The air outlet end of the air outlet duct is located inside the insulating bucket. The left-right rotating plates are installed up and down and rotatably connected to the air outlet end.

[0028] like Figures 1 to 6 As shown, it shows a specific embodiment of the present invention: the present invention discloses a heating and cooling device for an insulated bucket of an insulated boom truck, comprising a switch-type double-nozzle valve 1, a first insulating hose 2, a rotating joint 3, a second insulating hose 4, and an air outlet 5, wherein the switch-type double-nozzle valve 1 is installed on a hot and cold air main duct 6 outside the cab of the insulated boom truck, one end of the first insulating hose 2 is connected to the output port of the switch-type double-nozzle valve 1, the first insulating hose 2 is installed along the surface of the boom truck and fixed with a buckle 7, and the other end is connected to one end of the rotating joint 3, the rotating joint 3 is installed inside the turntable operating platform on the upper surface of the boom truck, the second insulating hose 4 is installed inside the telescopic arm of the boom truck, one end of which is connected to the other end of the rotating joint 3, the second insulating hose 4 is laid along the hydraulic pipeline inside the telescopic arm, and the second insulating hose 4 is fixed to the fixed frame inside the telescopic arm with a cable tie, the other end of the second insulating hose 4 extends out of the connection end of the telescopic arm connected to the air outlet 5, and the air outlet end of the air outlet 5 is located inside the insulated bucket.

[0029] In the present invention, Figure 1As shown, the switch-type double-nozzle valve 1 is installed on the hot and cold air main duct 6, and the hot air or cold air generated by the air-conditioning system on the insulating boom truck is changed in direction by adjusting the switch of the switch-type double-nozzle valve 1, and the hot air and cold air are transmitted to the insulating bucket through the first insulating hose 2 and the second insulating hose 4, so as to realize the effective utilization of resources when the insulating boom truck is in a working state, and at the same time ensure that the workers in the insulating bucket are in a comfortable working state while wearing heavy insulating clothes, insulating gloves and insulating boots, thereby ensuring the effective implementation of the operation process, improving work efficiency, realizing non-stop operation of the 10kV distribution network, and providing guarantee for the reliable and stable operation of power transmission.

[0030] In the present invention, Figure 5 , Figure 6 As shown, the hydraulic pipeline of the telescopic arm is connected to the oil tank, and the second insulating hose 4 is fixed on the fixing rod near the hydraulic pipeline. The distance between the fixing rod and the hydraulic pipeline is about 20-30 mm, which can fully realize the installation of the second insulating hose 4. Figure 5 This is the state of the telescopic arm before extension. Figure 6 This is the state of the telescopic arm after extension and retraction. The extension and retraction of the telescopic arm will not cause the second insulating hose 4 installed inside it to be twisted, thereby achieving effective transmission of cold air and hot air.

[0031] Specifically, the switch-type double-nozzle valve 1 includes a connecting pipe 11, a first switch 12, and a second switch 13. The connecting pipe 11 is a T-shaped structure. The first switch 12 is installed on the long side of the T-shaped structure, and the second switch 13 is installed on the short side of the T-shaped structure. Both ends of the long side of the connecting pipe 11 are connected to the cold and hot air main ducts 6, and the short side of the connecting pipe 11 is connected to the first insulating hose 2.

[0032] In the present invention, Figure 2As shown, the output end of the first switch 12 of the switch-type double-nozzle valve 1 is connected to the cab, and the on-off state of the first switch 12 controls the on-off state of the cold and hot air of the air conditioner entering the cab. The output end of the second switch 13 is connected to the first insulating hose 2, and the on-off state of the second switch 13 controls the on-off state of the cold and hot air of the air conditioner entering the insulating bucket. By installing the switch-type double-nozzle valve 1 on the cold and hot air main duct 6 outside the cab of the insulating boom truck, fast switching in different usage scenarios can be achieved. When the operator needs to work in the insulating bucket, the first switch 12 is closed and the second switch 13 is opened, and the cold air or hot air flows along the first insulating hose 2 and the second The insulating hose 4 enters the insulating bucket to provide a comfortable working environment for the operators and improve the working efficiency. When the insulating boom truck is in the situation stage and there are no operators in the insulating bucket, the first switch 12 is turned on and the second switch 13 is closed, and cold air or hot air enters the cab to provide a comfortable environment for the driver. The process can be completed by turning on and off the first switch 12 and the second switch 13. The operation is simple and convenient. At the same time, since the engine of the insulating boom truck must not be turned off when it is in working condition, the cold air or hot air that should have been led to the cab is sent into the insulating bucket, which effectively utilizes the resources, reduces costs, and realizes the reasonable allocation and reuse of resources.

[0033] Specifically, the first insulating hose 2 and the second insulating hose 4 are made of steel wire reinforced polyurethane hose or steel wire reinforced nylon hose.

[0034] In the present invention, a steel wire reinforced polyurethane hose or a steel wire reinforced nylon hose is used, which can withstand the 10kV voltage intensity of the power construction site to ensure the safety of the operation. At the same time, the material has a certain bending strength and will not break or tear when installed in the telescopic arm, ensuring the effective transmission of hot air and cold air.

[0035] Specifically, the diameter of the switch type double nozzle valve 1 is 30-40 mm.

[0036] In the present invention, a switch-type double-nozzle valve 1 with a diameter of 30-40 mm is used to adapt to the cold and hot air main ducts 6 on the insulating bucket arm truck at the current operation site, ensuring reliable and effective installation.

[0037] Specifically, the connection between the first insulating hose 2 and the switch-type double-nozzle valve 1 and the rotating joint 3 is fixed by a fixed clamp, and the connection between the second insulating hose 4 and the rotating joint 3 and the air outlet 5 is fixed by a fixed clamp.

[0038] In the present invention, a fixing clamp is used at the connection to fix it, so that it is reliably and effectively connected to avoid air leakage, thereby ensuring the effective operation of the temperature rise and fall device.

[0039] Specifically, the rotating joint 3 is a movable joint that can rotate 360 ​​degrees.

[0040] In the present invention, a 360° rotatable flexible joint is used. When the turntable on the upper surface of the insulated boom truck rotates, it drives the rotating joint 3 to rotate, and the first insulating hose 2 and the second insulating hose 4 connected at both ends of the rotating joint 3 will not rotate, thereby avoiding entanglement that causes the first insulating hose 2 and the second insulating hose 4 to tear or twist, thereby realizing the effective transmission of cold air and hot air by the device.

[0041] Specifically, the air outlet 5 includes an air outlet duct 51, a left-right rotating plate 52, an up-down rotating plate 53, and an adjustment switch 54. The connecting end of the air outlet duct 51 is a cylindrical structure, and its size is adapted to the diameter of the second insulating hose 4. The air outlet end of the air outlet duct 51 is located inside the insulating bucket. The left-right rotating plate 52 is installed up and down and rotatably connected to the air outlet end. The up-down rotating plate 53 is installed left-right and rotatably connected to the air outlet end and is located in front of the left-right rotating plate 52. The adjustment switch 54 is installed in the middle position of the up-down rotating plate 53, and one end inside the adjustment switch 54 is connected to the left-right rotating plate 52.

[0042] In the present invention, Figure 4 As shown, the air outlet duct 51 is installed in the insulating bucket, and the left and right rotating plates 52 and the up and down rotating plates 53 control the blowing direction of the wind. The blowing needs of different positions in the insulating bucket are met by adjustment. The wind direction is adjusted by the adjustment switch 54 installed on the up and down rotating plates 53. The operation is simple, and the operators in the insulating bucket can make adjustments according to actual usage needs.

[0043] Specifically, the buckle 7 is made of insulating material, and has fixing holes 71 at both ends thereof, and is fixed to the surface of the boom truck by bolts.

[0044] In the present invention, Figure 3 As shown, the first insulating hose 2 is fixed by the buckle 7, the first insulating hose 2 is placed in the arc structure of the buckle 7, and is fixed in the fixing hole 71 with bolts to fix the first insulating hose 2 on the upper surface of the insulating boom truck so that it is installed in an orderly and neat manner.

[0045] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
