Description

Technical Field

[0001] This utility model relates to the field of rescue pump technology, specifically to a flood control and disaster relief emergency pump. Background Technology

[0002] With the development of flood control and disaster relief technologies, various emergency pumps have been widely used in flood relief scenarios. However, these products still have some problems in actual use. For example, the connection between existing water pumps and water pipes is mostly fixed with flanges and bolts, or, in emergencies, with wire. This traditional connection method is complex and time-consuming, and cannot meet the needs of rapid deployment in emergency rescue. In addition, the wire fixing method also carries the risk of an unstable connection, which may affect rescue efficiency and safety.

[0003] Publication number CN113263877B discloses a remotely controlled water rescue device, which includes a rescue main body, a lifting bracket and an automatic fire monitor fixed to the rescue main body, and achieves water flow control through an inlet and an outlet diverter. However, the water pipe connection of this device relies on a traditional interface structure, making the installation process cumbersome and requiring additional tools to complete the connection operation. In emergency scenarios such as flood control and disaster relief, this connection method may lead to prolonged equipment deployment time and delays in rescue operations. In addition, although its jet propulsion design can improve propulsion efficiency, it is not optimized for quick assembly and disassembly and portability, making it difficult to adapt to the needs of rapid transfer in complex terrain.

[0004] The aforementioned problems indicate that current emergency pumps and related equipment on the market are insufficient to effectively meet the demands for rapid installation, convenient connection, and efficient operation in flood control and disaster relief scenarios. Therefore, this invention provides a flood control and disaster relief emergency pump to overcome these shortcomings and achieve a more efficient, convenient, and adaptable solution for complex rescue environments. Summary of the Invention

[0005] The purpose of this invention is to provide an emergency pump for flood control and disaster relief, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a flood control and emergency pump is provided, comprising a pump body, a quick-connect assembly, a hydraulic rod, and a wedge. The pump body has an inlet pipe and a drain pipe. The quick-connect assembly is mounted on the drain pipe and includes a housing, a baffle, a magnet, and a pressure block. One end of the housing has a mounting hole, and the other side has a through hole. The axial surface of the drain pipe has a groove. The pressure block is arranged in a ring around the drain pipe and has an inclined surface on its outer side and a protrusion on its inner side that mates with the groove. The baffle divides the interior of the housing into two areas. The magnet is located in the area near the wedge. The output end of the hydraulic rod is connected to the wedge. The inner side of the wedge has an inclined surface that mates with the inclined surface of the pressure block.

[0007] Furthermore, the side of the baffle that contacts the pressure block is provided with a limiting protrusion and a limiting groove. The limiting protrusion and the limiting groove cooperate to limit the movement direction of the pressure block. In particular, when all the pressure blocks are fully pressed, they are combined to form a hollow frustum structure, which firmly binds the water pipe to the surface of the drain pipe.

[0008] Furthermore, the end of the wedge remains in partial contact with the pressure block during the withdrawal process to provide support for the inclined surface of the pressure block, thereby preventing the pressure block from tilting due to magnetic force and affecting subsequent connection operations.

[0009] Furthermore, the number of pressure blocks is no less than three, and the number of hydraulic rods and wedges corresponds one-to-one with the number of pressure blocks.

[0010] Furthermore, the magnet is made of permanent magnet material and has a ring structure.

[0011] Furthermore, the outer shell is made of stainless steel, and the pressure block and wedge are made of high-hardness alloy material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The quick-connect assembly enables rapid connection and disconnection of water pipes, significantly improving the efficiency of flood control and disaster relief emergency response. It is suitable for rescue scenarios with tight time constraints. The hydraulic rod drives the wedge block and the inclined surface of the pressure block to make the pressure block evenly and firmly press the water pipe, effectively preventing the water pipe from loosening or falling off under high pressure, thus improving the reliability and safety of the connection.

[0014] By utilizing the synergistic effect of magnets and wedges, the pressure block is ensured to quickly reset during disassembly. At the same time, the wedges provide support for the pressure block, preventing it from tilting or getting stuck, thus ensuring the stability and durability of the device for repeated use.

[0015] The device has a simple and reasonable overall structure and is easy to operate. It can be installed and disassembled without the need for professional tools or complicated skills, which lowers the threshold for use and greatly saves installation difficulty and time.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0025] Please see Figures 1-5 As shown, a flood control and emergency pump is provided, such as... Figure 1 and Figure 2 As shown, the water pump body 1, as the core part of the entire device, is equipped with an inlet pipe 2 and a drain pipe 3, used for liquid input and output respectively. The quick-connect assembly 4 is installed on the drain pipe 3, and its structure is as follows. Figure 3 and Figure 4 As shown, the specific components include a housing 401, a baffle 402, a magnet 403, and a pressure block 404. One end of the housing 401 has a mounting hole 405, and the other end has a through hole 406 for inserting a water pipe to be connected and for the hydraulic rod 5 to drive the wedge block 6 into place.

[0026] In particular, the combination design of the hydraulic rod 5 and the wedge block 6 is one of the core innovations of this utility model. The output end of the hydraulic rod 5 is connected to the wedge block 6, and the inner side of the wedge block 6 is provided with an inclined surface, which cooperates with the inclined surface of the pressure block 404. Under the action of the hydraulic rod 5, the wedge block 6 is pushed through the through hole 406 and comes into contact with the pressure block 404, thereby realizing the action of the pressure block 404 squeezing the drain pipe 3. Furthermore, the end of the wedge block 6 maintains partial contact with the pressure block during the withdrawal process to prevent the pressure block from tilting due to magnetic force and ensure that subsequent wedge blocks can be properly inserted.

[0027] The drain pipe 3 has a groove 7 on its axial surface to enhance the locking effect of the pressure block 404 on the water pipe. The pressure block 404 is arranged in a ring around the drain pipe 3, with an inclined surface on its outer side and a protrusion on its inner side that mates with the groove 7, so that it can move in a specific direction and firmly clamp the water pipe when subjected to external pressure. The baffle 402 divides the interior of the housing 401 into two areas, and the magnet 403 is located in the area near the wedge 6 to attract the pressure block 404 away from the surface of the drain pipe 3 during disassembly.

[0028] Further analysis of the specific structure and operating principle of quick-connect component 4, such as... Figures 3-5 As shown, the design of the baffle 402 plays a crucial role. The baffle 402 divides the interior of the housing 401 into two areas: the magnet 403 is located near the wedge 6, while the pressure block 404 is located on the other side. This arrangement allows the magnet 403 to efficiently attract the pressure block 404 away from the surface of the drain pipe 3 during disassembly, without interfering with the normal operation of other components. Furthermore, the arrangement of the limiting protrusions and limiting slots 8 is carefully optimized to ensure that the movement trajectory of the pressure block 404 remains consistent during force application, avoiding loosening or damage caused by uneven force.

[0029] To facilitate manufacturing and maintenance, all components of the quick-connect assembly 4 are made of high-strength materials, possessing excellent wear resistance and corrosion resistance, enabling long-term use in harsh environments. For example, the housing 401 is made of stainless steel, which has high mechanical strength and corrosion resistance; the pressure block 404 and wedge block 6 are made of high-hardness alloy materials, ensuring that they are not easily deformed or damaged during repeated stress. The magnet 403 is made of high-performance permanent magnet material, possessing strong magnetic force, and can reliably attract the pressure block 404 away from the surface of the drain pipe 3.

[0030] During installation, the water pipe to be connected is first inserted into the side where the mounting hole 405 is located and fitted onto the surface of the drain pipe 3. At this time, the hydraulic rod 5 is activated, pushing the wedge 6 through the through hole 406 and into contact with the inclined surface of the pressure block 404. Figure 4As shown, the inner inclined surface of the wedge 6 is tightly fitted with the outer inclined surface of the pressure block 404. Under the action of the hydraulic rod 5, the wedge 6 gradually applies pressure to the pressure block 404, causing the pressure block 404 to move towards the surface of the drain pipe 3 along the extension direction of the limiting groove 8. The side of the baffle 402 that contacts the pressure block 404 is respectively provided with a limiting protrusion and a limiting groove 8. The cooperation of the limiting protrusion and the limiting groove 8 ensures that the movement trajectory of the pressure block 404 is always consistent, avoiding the problem of offset or misalignment caused by uneven force. When the wedge 6 is fully inserted, the pressure block 404 firmly presses the water pipe onto the surface of the drain pipe 3. The protrusion on the inner side of the pressure block 404 is precisely matched with the groove 7 on the axial surface of the drain pipe 3, increasing the contact area and significantly improving the stability of the connection, effectively preventing the water pipe from separating from the drain pipe 3.

[0031] During disassembly, the hydraulic rod 5 pulls the wedge 6 away, at which point the pressure block 404 loses the pressure from the wedge 6 and no longer exerts a binding force on the water pipe. Due to the presence of the magnet 403, the pressure block 404, under the action of magnetic force, moves away from the surface of the drain pipe 3 along the extension direction of the limiting groove 8, allowing the water pipe to be easily pulled out of the drain pipe 3. It should be noted that, in order to ensure the stability of the pressure block 404 during the removal process, the end of the wedge 6 is not completely detached from the pressure block 404, but maintains partial contact with it, providing support for the inclined surface of the pressure block 404 and preventing the pressure block 404 from tilting due to magnetic force, which would affect subsequent connection operations. This design not only improves the reliability of the device but also extends its service life.

[0032] During installation and disassembly, the operation of this device is simple and intuitive, requiring no complex tools or professional skills. Users simply insert the water pipe to be connected into the mounting hole 405 and activate the hydraulic rod 5 to quickly secure the pipe. For disassembly, simply activate the hydraulic rod 5 to retract the wedge block 6, and the water pipe can be easily removed. This convenient operation greatly reduces the difficulty for users, saves time in rescue and disaster relief efforts, and also reduces the risk of equipment damage due to improper operation.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
