TECHNICAL FIELD

[0001] The present application belongs to the field of self-lifting technology of heavy equipment, and particularly relates to a self-lifting device capable of preventing waterlogging. BACKGROUND

[0002] Heavy equipment, especially heavy equipment applied in remote suburbs, has a self-lifting loading and unloading function, which can save the cost and time of leasing hoisting equipment at the starting point of transportation. Therefore, self-lifting and self-loading and unloading devices or equipment, such as self-lifting and self-loading and unloading square cabins and self-lifting and self-loading and unloading SF6 recovery vehicles, are increasingly widely applied in the power industry.

[0003] Therefore, heavy rain, rainstorm or even flood will inevitably be encountered in the application site. When the water is high enough to submerge the chassis of such equipment, the water will enter the interior of the equipment. The interior detection equipment of such equipment applied in the power industry, such as a self-lifting and self-loading and unloading type power laboratory square cabin, is relatively expensive (the equipment value is up to several million), and once waterlogged, it will cause huge losses. For example, the self-lifting and self-loading and unloading type gas recovery device itself is also relatively expensive, and once waterlogged, the equipment will be damaged and the loss will be huge.

[0004] Therefore, a self-lifting device / equipment capable of preventing waterlogging is needed. SUMMARY

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a self-lifting device capable of preventing waterlogging.

[0006] The technical scheme adopted by the utility model is,

[0007] A self-lifting device capable of preventing waterlogging comprises a self-lifting device, a waterlogging-preventing sensing assembly and a control module.

[0008] The self-lifting device comprises a device body, a plurality of legs installed on the device body and a driving system for driving the legs to extend or retract to lift the device body.

[0009] The waterlogging-preventing sensing assembly comprises a waterlogging-preventing sensor and a mounting and fixing member of the sensor.

[0010] The control module comprises a control terminal installed in the self-lifting device and a man-machine interface for controlling the control terminal. The control terminal is connected to the driving system of the self-lifting device through a control line. The signal of the waterlogging-preventing sensor is connected to the data interface of the control terminal. The control terminal receives the waterlogging signal of the waterlogging-preventing sensor, sends a control signal to the driving system of the self-lifting device, and drives the legs installed on the device body to extend and lift the device body.

[0011] Further, the waterlogging-preventing sensor comprises a sensor for sensing the water level signal or the rainwater amount.

[0012] The sensor for sensing the water level signal is a float ball sensor, which is installed at the bottom of the device body and is not higher than the height of the bottom plate of the device body.

[0013] The sensor for sensing the rainwater amount is a water drop sensor, which is installed on the device body and is considered to be flooded when the detection value is greater than a certain value.

[0014] Further, the waterproof flooding sensor further comprises a height measuring sensor for measuring the height of the bottom plate of the device body from the water surface, and the output signal of the height measuring sensor is also connected to the data interface of the control terminal.

[0015] Specifically, the height measuring sensor is an ultrasonic range finder, a laser range finder, a depth finder or a radar water level gauge.

[0016] Further, the float ball sensor for sensing the water level signal is installed at the lower part of the leg and is not higher than the height of the bottom plate of the device body.

[0017] When the control terminal does not receive the flooded signal of the float ball sensor, the control terminal controls the driving system to drive the leg installed on the device body to retract until the self-lifting device body is lowered to the ground.

[0018] The self-lifting device can avoid huge economic losses caused by flooding of the self-lifting device or equipment after encountering heavy rain, even heavy rain or flood in the application site. Different waterproof flooding functions can be realized according to the type and installation position of the waterproof flooding sensor. The waterproof flooding sensor adopts a sensor for sensing the water level signal or sensing the rainwater amount, the float ball sensor for sensing the water level signal is installed at the bottom of the device body and is flooded when the float ball rises, the water drop sensor for sensing the rainwater amount is considered to be flooded when the detection value is greater than a certain value, and the control module controls the automatic lifting of the device body according to the flooded signal; when the waterproof flooding sensor further comprises a height measuring sensor, the extension height of the driving leg is further controlled, i.e. the lifting height of the device body, according to the measured height of the bottom plate of the device body from the water surface; when the float ball sensor for sensing the water level signal is installed at the lower part of the leg and the float ball descends, the flooded signal disappears and the device body is automatically triggered to descend.

[0020] As shown in the figure, a waterproof flooding self-lifting device comprises a self-lifting device, a waterproof flooding sensor assembly and a control module. Figure 1

[0021] ​The self-elevating device comprises a device body, a plurality of legs arranged on the device body, and a driving system for driving the legs to extend or retract to elevate the device body;

[0022] The water-flood-proof sensing assembly comprises a water-flood-proof sensor and a mounting fixture of the sensor;

[0023] The control module comprises a control terminal arranged in the self-elevating device and a human-machine interface for operating the control terminal, the control terminal is connected to the driving system of the self-elevating device by a control line, and a signal of the water-flood-proof sensor is connected to a data interface of the control terminal. When the water-flood-proof sensor is flooded, a flooded signal is sent to the control terminal, the control terminal receives the flooded signal, and the control terminal controls the driving system to drive the plurality of legs arranged on the device body to extend to elevate the device body.

[0024] The water-flood-proof sensor comprises a sensor for sensing a water level signal or a rainwater amount.

[0025] Specifically, the sensor for sensing the water level signal is a floating ball sensor arranged at a bottom of the device body and not higher than a height of a bottom plate of the device body. When the floating ball rises, a flooded signal is sent.

[0026] Specifically, the sensor for sensing the rainwater amount is a water drop sensor arranged on the device body, and when a detection value is greater than a certain value, the flooded signal is considered to be sent.

[0027] In an embodiment, the water-flood-proof sensor further comprises an altimeter sensor for measuring a height of the bottom plate of the device body from a water surface, and an output signal of the altimeter sensor is also connected to the data interface of the control terminal. When the height of the bottom plate of the device body from the water surface is greater than a preset height h, the control terminal outputs a control signal to the driving system to stop working, and the legs stop moving.

[0028] In an embodiment, the human-machine interface is a touch display screen, and the preset height h can be set through the human-machine interface.

[0029] In an embodiment, after heavy rain, heavy storm or flood stops, an operator of the self-elevating device can lower the self-elevating device body to the ground.

[0030] In an embodiment, the floating ball sensor for sensing the water level signal is arranged at a lower part of the leg and not higher than the height of the bottom plate of the device body, and when the floating ball descends, the flooded signal disappears, and the device body can be automatically lowered to the ground. Specifically, after a preset time T, the control terminal does not receive the flooded signal of the floating ball sensor for sensing the water level signal, the control terminal controls the driving system to drive the legs arranged on the device body to retract until the self-elevating device body is lowered to the ground.

[0031] Further, when the driving system is hydraulic driving, the hydraulic pump is controlled by the hydraulic pump controller to drive the outrigger to extend. When the bottom (chassis) of the self-lifting device body is higher than the water level by a preset distance h (the distance value can be set through the human-computer interaction interface), the control terminal sends a signal to stop the hydraulic pump.

[0032] In an embodiment, the self-lifting device can be a self-loading and unloading shelter, and can also be a self-loading and unloading SF6 recovery equipment, and can also be other lifting equipment. Here, no specific limitation is made. The common feature is that the device body is provided with a plurality of outriggers and a driving system for driving the outriggers to extend or retract to lift the device body. The embodiment of the self-lifting self-loading and unloading shelter can refer to the self-loading and unloading shelter disclosed in Patent No. CN216109932U. The self-lifting structure of the sulfur hexafluoride gas recovery vehicle can refer to the patent disclosed in Patent No. CN218912614U.

[0033] In an embodiment, the driving system of the self-lifting device is a hydraulic driving system, which includes a hydraulic pump, a hydraulic pump controller, and a hydraulic pipeline system for controlling the extension and retraction of the outriggers. The power line of the hydraulic pump is connected to the hydraulic pump controller, and the hydraulic pump controller is connected to the control terminal through a communication line. The hydraulic controller controls the operation of the hydraulic pump to drive the oil flow in the hydraulic pipeline system, and then the hydraulic pressure is transmitted to the hydraulic outriggers, i.e. the piston rod of the hydraulic cylinder, to extend or retract the piston rod relative to the hydraulic cylinder, thereby lifting the self-lifting device body.

[0034] In an embodiment, the driving system of the self-lifting device is an electric driving system, which includes a motor, a lead screw, a lead screw nut, and an extension leg. The rotation of the motor drives the connected lead screw to start rotating, thereby pushing the nut on the lead screw to start moving along the lead screw. The nut is fixed to the extension leg (i.e. the outrigger), and the nut pushes the extension leg to move. Thus, the extension leg extends or retracts, and the self-lifting device body is lifted.

[0035] In an embodiment, the water-flooding prevention sensing assembly can be a water droplet sensor and its mounting and fixing assembly, or a float ball sensor and its mounting assembly, or a combination of the two. The float ball sensor is installed at the bottom of the self-lifting device body, or at the bottom of the side wall, near the ground, and is not higher than the height of the chassis. As long as the rainwater does not rise above the chassis, the flooding signal can be sent to the control terminal in time to control the device body to be lifted to prevent flooding. When the detection value of the water droplet sensor is greater than a certain value, it is considered to be flooded, and the control module receives the flooding signal to control the device body to be lifted to prevent flooding.

[0036] The mounting and fixing assembly can be any assembly that can mount and fix the sensor to the bottom of the self-lifting device body, and no specific limitation is made.

[0037] In an embodiment, the water-flooding prevention sensor comprises a water level signal inductive sensor, and a float ball sensor for inducting the water level signal is arranged at a position not higher than the bottom of the device body, so that the rain water recession can be detected in time, the water-flooding signal disappears, the trigger condition occurs, and the device body is automatically lowered to the ground. If the control terminal does not receive the water-flooding signal of the float ball sensor of the water-flooding prevention sensor, the control terminal controls the driving system to drive the legs arranged on the device body to retract until the self-lifting and lowering device body is lowered to the ground.

[0038] In an embodiment, the control terminal comprises a processor, which can be a computer terminal, a tablet terminal, a mobile phone terminal, or a programmable PLC controller, as long as the control function can be realized, and no specific limitation is made.

[0039] It should be noted that the hydraulic driving system controls the legs arranged on the device body to extend or retract, which is a prior art. The electric driving system controls the legs to extend or retract, which is also a prior art. No further description is made herein.
