Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a self - propelled stair - climbing hydraulic pump, including a self - propelled pump main body 10 and a top - support mechanism 20;

[0023] The top - support mechanism 20 includes a top - support rod 201 and a drive rod 202 hinged to the self - propelled pump main body 10. A support wheel 203 is provided at the end of the top - support rod 201 away from the self - propelled pump main body 10. The top - support rod 201 has a first state and a second state. When the top - support rod 201 is in the first state, one end of the self - propelled pump main body 10 is tilted up and the outer ring of the support wheel 203 contacts the ground. When the top - support rod 201 is in the second state, the top - support rod 201 is parallel to the self - propelled pump main body 10;

[0024] The end of the drive rod 202 away from the self - propelled pump main body 10 is connected to the top - support rod 201, and the drive rod 202 is used to drive the top - support rod 201 to switch between the first state and the second state;

[0025] Through the setting of the self - walking pump body, it is used to walk to the usage position by itself during use, such as the location for pumping water from a water source or draining waterlogging, etc., to pump water. Through the connection between the driving rod 202 and the self - walking pump body, one end of the driving rod 202 can be flipped on the self - walking pump body. Through the connection between the top - supporting rod 201 and the self - walking pump body, one end of the top - supporting rod 201 can also be flipped on the self - walking pump body. The top - supporting rod 201 is set with a first state and a second state. When in the first state, it supports one end of the self - walking pump body, making one end of the self - walking pump body tilt up, and then continues to walk. The walking part contacts the edge of an obstacle (such as a step), generates frictional force and continues to move forward, and can climb stairs. When climbing the stairs, the top - supporting rod 201 is in the second state, avoiding the top - supporting rod 201 interfering with the walking of the self - walking pump body and affecting the movement of the self - walking pump body.

[0026] In this embodiment, as a preferred solution, the top - supporting rod 201 includes a top - supporting cylinder 2011 and a supporting rod 2012. One end of the top - supporting cylinder 2011 is sleeved on the surface of the supporting rod 2012 through a groove opened, and the supporting rod 2012 is slidably connected in the groove opened at one end of the top - supporting cylinder 2011;

[0027] Through the connection between the top - supporting cylinder 2011 and the supporting rod 2012, the supporting rod 2012 can extend or retract in the top - supporting cylinder 2011.

[0028] In this embodiment, as a preferred solution, one end of the top - supporting cylinder 2011 is hinged to the bottom of the self - walking pump main body 10, and the end of the supporting rod 2012 away from the top - supporting cylinder 2011 is rotatably connected to the supporting wheel 203 through a wheel groove opened;

[0029] Through the connection between the top - supporting cylinder 2011 and the self - walking pump main body 10, the top - supporting cylinder 2011 can be flipped at the bottom of the self - walking pump main body 10. Through the connection between the supporting rod 2012 and the top - supporting cylinder 2011, when the self - walking pump main body 10 needs to climb stairs, while the top - supporting cylinder 2011 flips, the supporting rod 2012 extends out of the top - supporting cylinder 2011, making the supporting wheel 203 contact the supporting surface (the ground), making one end of the self - walking pump main body 10 tilt up. Then the walking part of the self - walking pump main body 10 contacts the edge of the step and climbs. During the climbing process, the top - supporting cylinder 2011 flips, and the supporting rod 2012 is retracted into the top - supporting cylinder 2011 as the top - supporting cylinder 2011 flips. Through the fact that the supporting rod 2012 can be retracted into the top - supporting cylinder 2011, it can play a compensating role when the top - supporting cylinder 2011 changes to the second state, avoiding the connection between the top - supporting cylinder 2011 and the supporting rod 2012 being fixed and flipped, causing the supporting wheel 203 to contact the side of the step and interfering with the progress of the self - walking pump main body 10. At the same time, it can also save the occupied space, improve a certain degree of flexibility, and increase the applicable range, enabling the self - walking pump main body 10 to be applicable to climbing stairs with relatively high steps.

[0030] In this embodiment, as a preferred solution, the driving rod 202 is an electric telescopic rod. The fixed end of the driving rod 202 is hinged to the self-propelled pump main body 10, and the telescopic end of the driving rod 202 is hinged to the surface of the support rod 2012;

[0031] Through the action of the driving rod 202, it is used to adjust the extension or retraction of the support rod 2012, and at the same time, it can also adjust the flipping of the top support cylinder 2011. The electric telescopic rod is a well-known prior art and is only cited here.

[0032] In this embodiment, as a preferred solution, the self-propelled pump main body 10 includes a hydraulic pump body 101, a hydraulic power unit 102, and a self-propelled chassis 103. The hydraulic pump body 101 and the hydraulic power unit 102 are both arranged on the self-propelled chassis 103, and the hydraulic pump body 101 is located on one side of the hydraulic power unit 102. An avoidance opening for cooperating with the driving rod 202 is formed on the self-propelled chassis 103. There is a gap between the outer surface of the driving rod 202 and the inner wall of the avoidance opening, and one end of the driving rod 202 is hinged to the self-propelled chassis 103;

[0033] Both the hydraulic pump body 101 and the hydraulic power unit 102 are well-known prior arts. A battery pack is arranged in the hydraulic power unit 102 and can be charged for use as a power source. The self-propelled chassis 103 includes tracks, and the tracks are well-known prior arts and are only cited here. The tracks are driven by a motor through a gear support to operate and move. When climbing stairs, sufficient friction can be generated by fully contacting the edges of the stairs through the movement of the tracks. When the self-propelled chassis 103 tilts, it can also continue to move, and it has good stability during movement.

[0034] In this embodiment, as a preferred solution, it further includes a control component arranged on the self-propelled chassis 103. The control component includes a control module, a detection component, and a driver. The output end of the detection component is electrically connected to the input end of the control module. The detection component is used to detect obstacles relative to the self-propelled chassis 103 and the state of the self-propelled chassis 103 when crossing an obstacle. The output end of the control module is electrically connected to the input end of the driver, and the output end of the driver is electrically connected to the input end of the driving rod 202;

[0035] The control module, the detection component, and the driver are all well-known prior arts and are only cited here. The purpose is that the detection component detects obstacles of the self-propelled chassis 103 and the state of the self-propelled chassis 103 when crossing an obstacle, and transmits the signal to the control module in a timely manner. The control module controls the driving rod 202 to extend through the driver, so that while the top support cylinder 2011 flips, the support rod 2012 extends from the top support cylinder 2011.

[0036] In this embodiment, as a preferred solution, the detection member includes a first sensor, a second sensor, and a third sensor. The first sensor is disposed at the end of the self-propelled chassis 103, and the second sensor and the third sensor are both disposed at the bottom of the self-propelled chassis 103 and are spaced apart from each other.

[0037] The first sensor, the second sensor, and the third sensor are all optical sensors, which are well-known in the art.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
