Description

Technical Field

[0001] The present application relates to the technical field of ship components, and in particular to a flood disaster inspection ship for high-density old urban areas. Background Art

[0002] Natural disasters are natural phenomena that harm or damage the human living environment. Every year, various natural disasters cause huge losses to human production and life. Among them, floods are one of the more common natural disasters, especially in some high-density old urban areas. Due to the terrain or drainage problems, floods are very likely to occur in low-lying areas.

[0003] When flood disasters occur, in order to improve rescue efficiency and reduce unnecessary casualties, patrol boats are often dispatched to survey the situation in the flooded areas. However, when flood disasters occur in urban areas, a large amount of various plastic bags, ropes and other garbage generated in daily life will inevitably float in the water. In the process of surveying, plastic bags, ropes and other garbage are very likely to be entangled in the propellers, causing the rotation of the propellers to be obstructed or even unable to operate normally, which greatly affects the survey efficiency of the patrol boats and the subsequent search and rescue time, and their stability and reliability are poor.

[0004] Therefore, there is an urgent need for a propeller component for flood disaster inspection boats to solve the defects of the above-mentioned existing disaster inspection boats during actual use. Summary of the Invention

[0005] The present application proposes a flood inspection boat for high-density old urban areas, which has the advantage of effectively preventing plastic bags, ropes and other garbage from being entangled in the propeller of the inspection boat, causing its rotation to be obstructed or even unable to operate normally. It is used to solve the problem that when flood disasters occur in urban areas, a large amount of various plastic bags, ropes and other garbage generated in daily life will inevitably float in the water. As a result, when the inspection boat is conducting an inspection operation, plastic bags, ropes and other garbage are very likely to be entangled in the propeller, causing the rotation of the propeller to be obstructed or even unable to operate normally.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions: a high-density old city flood inspection boat, comprising a transmission shaft fixedly installed on the power equipment of the flood inspection boat and having a hollow structure, and a propeller fixedly installed at one end of the transmission shaft, and then when the power equipment is started, under the transmission action of the transmission shaft, the propeller can be driven to rotate at high speed to drive the flood inspection boat, three groups of card slots arranged in a ring array are provided inside the transmission shaft, and a linkage plate is movably connected inside the card slot, a slider is fixedly installed on one side of the top of the linkage plate, and an elastic sheet is provided on one side of the bottom end of the linkage plate, and is elastically connected to the transmission shaft through the elastic sheet, and then when the linkage plate is initially Under the elastic force of the elastic sheet, the linkage plate is maintained in the rightmost position. The top of the linkage plate is provided with a cutting tool whose end is pin-connected to one side of the inner groove, and a sliding groove cooperating with the slider is provided on one side of the bottom end of the cutting tool. At the same time, a connecting hole connected to the groove is provided on the left side of the outer surface of the transmission shaft, and the connecting hole is connected to the external hydraulic pump station through a movable sealing ring. When the plastic bag or rope is wrapped around the outer surface of the transmission shaft, the hydraulic pump station can be triggered to extract the hydraulic oil in the chamber formed by the linkage plate and the groove, and under the action of negative pressure adsorption, the linkage plate is driven to move to the left, and the cutting tool is forced to open outward to cut the plastic bag or rope wrapped around the outer surface of the transmission shaft.

[0007] Furthermore, the other end of the cutting tool is set as an arc-shaped protrusion structure and extends to the groove on the propeller that matches it. At the same time, the cutting tool is set as a square structure and has blades on both sides of its top, which can effectively improve the cutting efficiency of the cutting tool for plastic bags and ropes.

[0008] Furthermore, the right side of the linkage plate is bent upward, and a slope structure that cooperates with the linkage plate is provided on one side of the bottom end of the cutting tool. When the linkage plate moves to the left, the expansion range of the cutting tool above it can be effectively increased, thereby further improving its cutting efficiency for plastic bags and ropes.

[0009] Furthermore, an exhaust groove connected to the inner cavity of the transmission shaft is opened inside and at a position staggered from the cutting tool, and a piston column is movably sleeved inside the transmission shaft. The right side of the piston column is elastically connected to the right side of the inner cavity of the transmission shaft through an elastic member, and a pressure sensor is provided between the piston column and the right side of the inner cavity of the transmission shaft. At the same time, the left end of the transmission shaft is connected to the air pressure pump station through a movable sealing ring.

[0010] Furthermore, the air pressure pump station is always in the open state when the flood inspection boat is operating, and the air flow is discharged through the inner cavity of the transmission shaft and the exhaust groove. When the outer surface of the transmission shaft is wrapped with plastic bags and ropes, the flow rate of the exhaust groove for the air flow becomes smaller, and the piston column is forced to move to the right and squeeze the trigger pressure sensor while the air flow delivery volume remains unchanged.

[0011] Furthermore, a feedback electrical connection is formed between the pressure sensor and the hydraulic pump station through a control system, and when the pressure sensor is triggered by pressure, the hydraulic pump station is automatically triggered to cut the plastic bag and rope wrapped around the outer surface of the transmission shaft.

[0012] Furthermore, the diameter of the trajectory circles formed by the three groups of cutting tools is the same as the outer diameter of the transmission shaft, so as to reduce the resistance effect generated by the transmission shaft when it rotates at high speed in water.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present application provides a high-density old city flood disaster inspection boat. Regarding the setting of the linkage plate and the slider, when the outer surface of the transmission shaft is wrapped with plastic bags, ropes and other garbage, the hydraulic pump station can be triggered to extract the hydraulic oil in the chamber formed by the linkage plate and the slot, and under the action of negative pressure adsorption, the linkage plate is driven to move to the left, and the cutting tool is forced to expand outward to cut off the plastic bags, ropes and other garbage wrapped around the outer surface of the transmission shaft, thereby effectively preventing plastic bags, ropes and other garbage from being wrapped around the propeller of the inspection boat, causing its rotation to be obstructed or even unable to operate normally.

[0015] 2. The present application provides a high-density old city flood disaster inspection boat. Regarding the setting of the piston column, when the outer surface of the transmission shaft is wrapped with plastic bags, ropes and other garbage, the air flow volume of the exhaust groove becomes smaller, and the piston column is forced to move to the right and squeeze the pressure sensor while the air flow delivery volume remains unchanged, thereby triggering the hydraulic pump station to drive the cutting tool to expand outward and cut off the plastic bags, ropes and other garbage wrapped around the outer surface of the transmission shaft, and automatically controlling the movement of the cutting tool. It is simple to operate, easy to use and highly controllable. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 、 Figure 2 As shown, a high-density old city flood inspection boat includes a transmission shaft 1 fixedly installed on the power equipment of the flood inspection boat and having a hollow structure, and a propeller 2 is fixedly installed at one end of the transmission shaft 1. When the power equipment is started, the propeller 2 can be driven by the transmission action of the transmission shaft 1 to rotate at a high speed to drive the flood inspection boat. Figure 3 、 Figure 4 as well as Figure 5As shown, the interior of the transmission shaft 1 is provided with three groups of card slots 3 arranged in a circular array, and a linkage plate 6 is movably connected inside the card slot 3, a slider 7 is fixedly installed on one side of the top of the linkage plate 6, and an elastic sheet 8 is provided on one side of the bottom end of the linkage plate 6, and is elastically connected to the transmission shaft 1 through the elastic sheet 8, and then when the linkage plate 6 is initially in the rightmost position under the elastic force of the elastic sheet 8, the linkage plate 6 is maintained at the rightmost position, the top of the linkage plate 6 is provided with a cutting tool 9 whose end is pin-connected to one side of the inner side of the card slot 3, and a cutting tool 9 is provided on one side of the bottom end of the cutting tool 9. 7 cooperates with the slide 10, and at the same time, a connecting hole 4 connected to the card slot 3 is opened on the left side of the outer surface of the transmission shaft 1, and the connecting hole 4 is connected to the external hydraulic pump station through a movable sealing ring. When plastic bags, ropes and other garbage are wrapped around the outer surface of the transmission shaft 1, the hydraulic pump station can be triggered to extract the hydraulic oil in the chamber formed by the linkage plate 6 and the card slot 3, and under the action of negative pressure adsorption, the linkage plate 6 is driven to move to the left, and the cutting tool 9 is forced to open outward to cut off the plastic bags, ropes and other garbage wrapped around the outer surface of the transmission shaft 1.

[0027] like Figure 1 、 Figure 5 As shown, in the present technical solution, the other end of the cutting tool 9 is set as an arc-shaped protrusion structure and extends to the groove on the propeller 2 that matches it. At the same time, the cutting tool 9 is set as a square structure and is sharpened on both sides of its top, thereby effectively improving the cutting efficiency of the cutting tool 9 for plastic bags, ropes and other garbage.

[0028] like Figure 2 、 Figure 4 as well as Figure 5 As shown, in the present technical solution, the right side of the linkage plate 6 is bent upward, and a slope structure that cooperates with the linkage plate 6 is provided on one side of the bottom end of the cutting tool 9. Therefore, when the linkage plate 6 moves to the left, the expansion range of the cutting tool 9 above it can be effectively increased, thereby further improving its cutting efficiency for garbage such as plastic bags and ropes.

[0030] In this technical solution, the air pressure pump station is always in the open state when the flood inspection boat is operating, and the air flow is discharged through the inner cavity of the transmission shaft 1 and the exhaust groove 5. When the outer surface of the transmission shaft 1 is wrapped with plastic bags, ropes and other garbage, the flow rate of the exhaust groove 5 for the air flow becomes smaller, and the piston column 11 is forced to move to the right and squeeze the trigger pressure sensor 13 while the air flow delivery volume remains unchanged.

[0031] In this technical solution, a feedback electrical connection is formed between the pressure sensor 13 and the hydraulic pump station through the control system, and when the pressure sensor 13 is triggered by pressure, the hydraulic pump station is automatically triggered to cut off plastic bags, ropes and other garbage wrapped around the outer surface of the drive shaft 1.

[0032] like Figure 2 As shown, in this technical solution, the diameter of the trajectory circle formed by the three groups of cutting tools 9 is the same as the outer diameter of the transmission shaft 1, so as to reduce the resistance effect generated by the transmission shaft 1 when it rotates at high speed in water.

[0033] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
