Example 1

[0034] This embodiment introduces a rescue suction device, including a handheld suction device and a negative pressure device;

[0035] The handheld suction device comprises a suction head 1, a connecting pipe 9, a conveying pipe, an armrest 4 and a moving device; the rear end of the suction head 1 is connected to the connecting pipe 9; the moving device is arranged below the connecting pipe 9 to bear the weight of the handheld suction device and the sucked material; the armrest 4 is arranged above the connecting pipe 9;

[0036] The delivery pipe transmits the material sucked by the handheld suction device to the periphery of the rescue area;

[0037] The negative pressure device is connected to the handheld suction equipment to deliver high-pressure and high-flow airflow to the handheld suction equipment, thereby generating negative pressure suction to suck in materials in the rescue area.

[0038] This embodiment overcomes the defects of the prior art that the suction equipment is heavy, difficult to operate by one person for a long time, and not portable; the negative pressure device conveys high-pressure and high-flow airflow to the handheld suction equipment, generates negative pressure suction, sucks in materials in the rescue area, and the conveying pipe conveys the materials sucked into the conveying pipe to outside the rescue area; the design of the mobile device in the suction equipment ensures that the handheld suction equipment is in a horizontal state, and the weight of the suction equipment and the suction material in the suction pipe are all on the casters of the mobile device; the setting of the armrest makes it convenient for the operator to grasp the suction equipment to adjust the suction direction, reduces the operating intensity of the rescue personnel, and allows the operator to focus on the rescue process of the buried persons. Example 2

[0039] Based on Example 1, this example introduces a specific implementation of a rescue suction device and further explains the structure of each unit:

[0040] The negative pressure device is connected to the handheld suction equipment to deliver high-pressure and high-flow airflow to the handheld suction equipment, thereby generating negative pressure suction to suck in materials in the rescue area. Then, the materials are transported backwards under the action of air force and transported to the peripheral area of ​​the rescue scene through a conveying pipe.

[0041] The utility model designs two usage methods of a handheld suction device and a negative pressure device adapted thereto. The first connection method of the handheld suction device is briefly described as a first handheld suction device; the second connection method of the handheld suction device is briefly described as a second handheld suction device.

[0042] The handheld suction device, such as Figure 1 The figure shows a suction head 1, a connecting pipe 9, a handrail 4, a moving device and a material output pipe 6. The suction head 1 sucks sand, gravel and other materials from the ground, and a rubber suction nozzle 11 is connected to the inlet thereof to avoid secondary damage to the buried personnel caused by the hard suction head during the rescue process. The suction head 1 is provided with a variety of shapes and configurations, which can be flexibly replaced according to the actual rescue scene and materials. The rear end of the suction head 1 is connected to the connecting pipe 9.

[0043] The handrail 4 is arranged above the connecting pipe 9, which is convenient for the operator to hold the rescue suction device to adjust the suction direction. The mobile device includes a bracket, a rear caster 8.1 and a front caster 8.2. The bracket is arranged below the connecting pipe 9. The rear caster 8.1 and the front caster 8.2 are fixedly connected to the bracket to ensure that the handheld suction device is in a horizontal state. The weight of the handheld suction device and the suction object in the suction pipe is all on the casters, which reduces the operating intensity of the rescue personnel.

[0044] The material output pipe 6 is a hose several tens of meters long, which is installed at the rear end of the connecting pipe 9 through a hose clamp 5. The material output pipe 6 transports the sucked material to the peripheral area of ​​the rescue scene.

[0045] During the actual rescue process, the operator needs to always pay attention to the status and position of the buried person, so operating in a squatting position is more suitable for actual rescue scenarios; and the handheld suction equipment in this technical solution requires the operator to operate in a squatting position.

[0046] The handheld suction device in this technical solution is simple in form, has no redundant design, is light in weight, and is more convenient to carry. The weight of the suction device and the suctioned material in the pipeline are all on the casters. The operator only needs to hold the handle to adjust the suction direction, which greatly reduces the operator's labor intensity and allows the operator to focus on the rescue process of the buried person.

[0047] The negative pressure device corresponding to the first handheld suction device includes an air compressor, an air inlet pipe 7, a switch valve 3 and a pneumatic conveyor 2;

[0048] The pneumatic conveyor 2 is fixedly connected between the suction head 1 and the connecting pipe 9 through a sealed clamp 10. The pneumatic conveyor 2 is configured to generate negative pressure suction at the inlet of the rubber suction nozzle 11 of the equipment to suck in the material through the suction head 1; the switch valve 3 is arranged at the air inlet of the pneumatic conveyor 2 to control the on and off of the airflow.

[0049] The air inlet pipe 7 is used to deliver high-pressure and high-flow air to the suction device. One end of the air inlet pipe 7 is connected to the air compressor, and the other end is connected to the switch valve 3. The air inlet pipe 7 and the switch valve 3 are connected in a quick-plug and quick-twist manner, which is convenient for quick connection during rescue operations. The high-pressure and high-flow air generated by the air compressor is delivered through the air inlet pipe 7, and the pneumatic conveyor enables the handheld suction device to generate negative pressure suction to suck in materials in the rescue area.

[0050] The air volume and air pressure of the air compressor can meet the vacuum suction of sand and gravel of at least two sets of suction equipment; the structural schematic diagram of the air compressor is as follows Figure 2As shown, it includes: gasoline engine 13, battery 14, electric control cabinet 15, radiator 16, air pump 17, tool box 18, hose storage rack 19 and installation platform 20. The air compressor equipment is divided into eight independent modules, such as Figure 3 As shown, the weight of a single module does not exceed 50kg, and each module has a hand pull ring for easy manual handling. Each functional module is connected to the installation platform 20 with a unified bolt connection, and the electric wrench in the tool box 18 can be used to achieve manual quick installation and connection.

[0051] The gasoline engine 13, battery 14, radiator 16, air pump 17, gas tank and other components are conventional basic configurations of an air compressor, and their functions are not described in detail, and only the design matching the present utility model is described.

[0052] The installation platform 20 is provided with tires and handrails to meet the needs of manually moving the air compressor on site.

[0053] The tool box 18 is configured to store tools required for installing the air compressor.

[0054] The hose storage rack 19 is configured to store the air inlet pipe 7 and the material output pipe 6; when not in operation, the material output pipe 6 and the air inlet pipe 7 are stored on the air compressor device, so as to facilitate quick connection to the suction device during rescue.

[0055] The electric control cabinet 15 is equipped with basic functions such as equipment start and stop control, equipment operation status and parameter display; in addition, it is equipped with an air output adjustment knob to facilitate real-time adjustment of the air output to the suction equipment according to the on-site suction situation; at the same time, it can flexibly control the independent or simultaneous suction operation of the two sets of suction equipment, and adjust the suction force by flexibly adjusting the input air volume and on and off of the two sets of suction equipment, saving energy and reducing consumption while adapting to the suction of materials with different particle sizes. The electric control cabinet 15 reserves a power interface for night rescue lighting.

[0056] Figure 4 The figure shows a rescue operation state diagram using the first handheld suction device and its negative pressure device. The rescuer operates in a squatting position, which is convenient for keeping an eye on the status and position of the buried person. One set of air compressors connects two sets of suction devices to speed up the suction efficiency. If the suction material particles are large or the suction material is small, one set of suction devices can be turned off to increase the suction force and suction speed. The rescue equipment can also suck out spilled crude oil and clean up abandoned soil in narrow areas.

[0057] The air compressor in this technical solution meets the gas demand of suction equipment in rescue scenarios. It is movable, modular, portable, and quick to assemble. At the same time, it can flexibly adjust the suction force according to the suction conditions to better meet the needs of emergency rescue scenarios.

[0058] like Figure 5 The figure shows the second connection and installation method of the handheld suction device of the utility model, namely the second handheld suction device. Compared with the first connection method, the second handheld suction device eliminates the pneumatic conveyor 2, the switch valve 3 and the air inlet pipe 7, and the connecting pipe 9 of the second handheld suction device is directly connected to the suction head 1 through a sealed clamp 10.

[0059] The negative pressure device is matched Figure 5 The second handheld suction device shown is a large negative pressure suction device, and the large negative pressure suction device is as shown in FIG. Figure 6 As shown. The large negative pressure suction device is a rescue vacuum suction vehicle or robot. The front end of the material output pipe 6 is connected to the second handheld suction device, and the rear end is connected to the top of the vacuum silo of the large negative pressure suction device. Since the vacuum silo generates negative pressure, the material is sucked into the vacuum silo through the material output pipe 6. The large negative pressure suction device has a strong suction capacity and can be matched with multiple groups of handheld suction devices.

[0060] The handheld suction device is connected in sections by a clamp, which enables flexible switching between two connection methods. In rescue suction scenarios, it can be matched with an air compressor for suction, and can also be connected to a large negative pressure suction device for suction. The device has a wide range of applications.

[0061] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification and equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
