Description

Technical Field

[0001] The present technical solution relates to the technical field of floating body pump equipment, and in particular to a floating body pump. Background Art

[0002] A floating pump is a type of pump equipment used for large-flow drainage and rescue operations with its main function being flood control and drainage. It is small in size and light in weight. The pump body is installed on a float, allowing the entire pump unit to float on the water surface and work.

[0003] For example, Chinese patent CN203214266U discloses a floating fire pump device, including two parallel rectangular iron frames, a fixed buoyancy box is built into the upper part of the rectangular iron frame, and a filter chamber is formed by surrounding the lower part with a filter screen, a fire pump is placed in the filter chamber, the outlet pipe of the fire pump is erected on the rectangular iron frame, the filter screen is plugged into the vertical slot on the outer periphery of the rectangular iron frame, a crossbeam is mounted on the two rectangular iron frames, and a plurality of removable small buoyancy boxes are arranged under the crossbeam. The floating fire pump device can provide water for fire fighting, and the two water pumps work at the same time to absorb water. When working, they float on the water surface and are not easy to sink. They will not absorb silt on the bottom of the water to block the water pump, and they can quickly clean impurities on the filter screen.

[0004] The above-mentioned floating fire water pump device, the existing floating pump generally adopts a fixed float installed above the water pump to realize its floating and stable pumping function, and fixes the fixed float box below with a rectangular iron frame to realize the installation between the float box and the water pump. There is a situation where the distance between the pump body and the water surface is too close. The close distance setting can easily cause the pump body to inhale air during the pumping process, reduce the pumping efficiency of the pump body, and may damage the inside of the pump body, thereby affecting the normal use of the pump body, resulting in poor performance stability, which needs to be improved. Summary of the invention

[0005] In order to improve the problem that the floating body drives the pump body too close to the water surface, resulting in poor performance stability, this technical solution provides a floating body pump.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A floating pump comprises a pump body and a buoyancy box, which is installed above the pump body through a fixing assembly so that the pump body can be completely immersed below the water surface.

[0008] Through the above technical solution, when the float pump is used normally, the float box is used in conjunction with the fixing component, which is tightly wrapped around the pump body and firmly connected through the fixing component, so that the pump body can be fixed under the float box. When the float box floats on the water surface and tends to be stable, the pump body is completely immersed below the water surface and maintains a certain distance from the water surface. It is placed in a suitable position in the water to avoid empty suction, thereby making the drainage operation more stable.

[0009] Preferably, the fixing assembly includes at least one flexible connector, which is wound around the pump body and connected to the buoyancy box, so as to achieve relative fixation between the buoyancy box and the pump body.

[0010] Through the above technical solution, at least one flexible connector is bent and wrapped around the pump body to ensure the firmness of the connection between the pump body and the buoyancy tank, and its flexibility improves the adaptability of the flexible connector to the fixed use of different pump bodies.

[0011] Preferably, a flow groove is formed on one side of the buoyancy box corresponding to the pump body, and the pump body can be axially fixed relative to the flow groove.

[0012] Through the above technical scheme, the shape of the circulation groove is designed to be compatible with the pump body so as to accommodate one side of the top of the pump body, thereby improving the positioning effect of the pump body installation, and at the same time leaving space between the pump body and the buoyancy box, so that the floating pump can fully absorb water and effectively drain water during operation, thereby ensuring its reliable performance and improving work efficiency.

[0013] Preferably, the lower edge of the pontoon is provided with a plurality of through holes, and the through holes are evenly distributed on both sides of the pontoon along the length direction of the pontoon;

[0014] The flexible connector is inserted into the corresponding penetration hole and wound around the pump body, thereby fixing the pump body to the lower end of the buoyancy tank.

[0015] Through the above technical solution, the flexible connector is inserted into different connection holes to realize different fixing positions and fixing methods, thereby realizing stable fixation of the pump body and further improving applicability.

[0016] Preferably, the floating box is provided with conveying grooves on the side walls on opposite sides along a groove parallel to the circulation groove, and the through-holes are provided on the inner side walls of the conveying grooves;

[0017] The transport slot comprises a first transport slot provided with a plurality of through holes;

[0018] The transport groove further comprises a second transport groove provided with at least one penetration hole.

[0019] Through the above technical solution, both hands are buckled into the carrying grooves on both sides, which makes it convenient to buckle against the upper inner wall to firmly grasp the buoyancy box during transportation or installation, so as to carry the entire pump body into the water, further improving practicality and ease of operation.

[0020] The first conveying trough utilizes the internal space of the conveying trough to arrange the through holes, and the through holes in different positions are selected for connection through the flexible connector, which can ensure that the flexible connector can fix the pump body at a better angle and position, improve the stability of the connection, and adapt to more types of pump bodies, further enhancing its versatility.

[0021] The second conveying groove is arranged in parallel with the first conveying groove, and at least one through hole is arranged in the groove. The through hole cooperates with the through hole in the first conveying groove to provide more connection points for the flexible connector.

[0022] Preferably, the flexible connector is bent to form a first pipe segment and a second ring segment, the second ring segment is fixed around the pump body, and the first pipe segment is connected to the second ring segment and is passed through the through holes on both sides.

[0023] Through the above technical scheme, the flexible connector is divided into two parts, the first pipe segment and the second ring segment, each of which has a different function. The second ring segment circumferentially surrounds the outer surface of the pump body, and is wrapped with its flexibility to closely fit the surface of the pump body to achieve initial binding. The through holes on the buoyancy box are opened one by one on the opposite sides of the buoyancy box along the length direction of the pump body. Based on the connection between the first pipe segment and the second ring segment, the first pipe segment is the continuation of the two ends of the second ring segment. It naturally extends and passes through the corresponding through holes on both sides to form a closed supporting structure under the pump body, thereby achieving relative fixation between the buoyancy box and the pump body and improving the stability of the connection.

[0024] Preferably, the flexible connection member is a rope or a steel wire.

[0025] Through the above technical scheme, ropes or steel wires with good flexibility are selected, which have strong plasticity and can reduce the fitting gap between the pump body, forming a more stable supporting structure, further keeping the pump body in a relatively stable state.

[0026] Preferably, the buoyancy box is provided with a clearance cavity, and the through end of the clearance cavity corresponding to the bottom of the flow groove is used to be arranged corresponding to the water inlet of the pump body.

[0027] Through the above technical solution, the buoyancy chamber is opened in the float box. As the weight of the water displaced by the float box is reduced, the buoyancy of the float box will also be reduced accordingly. The float box will sink a little when it reaches a balanced state again to increase its underwater body, thereby displacing more water to restore sufficient buoyancy to support its weight, ensuring that the pump body can be immersed in the appropriate water depth.

[0028] The giving way cavity is arranged corresponding to the water inlet of the pump body, which further reduces the interference with the water pumping of the pump body, so that the pump body can absorb water more smoothly, thereby significantly improving its water absorption efficiency.

[0029] Preferably, the fixing assembly further comprises a metal connecting piece, which is arranged on the buoyancy box and clamped to the outside of the pump body.

[0030] Through the above technical solution, a metal connector is added, both ends of which are connected to the lower end surface of the buoyancy tank and straddle the pump body to tighten, so as to further improve the fixing stability of the pump body.

[0031] Preferably, a groove is formed on one side of the floating box, and a connection hole is formed through the inner wall of the groove for a flexible connecting member to pass through.

[0032] Through the above technical solution, a groove is provided on one side of the floating box, and a connection hole is formed through the inner wall of the groove for the flexible connecting member to pass through, thereby further improving the fixing stability of the pump body.

[0033] The prominent and beneficial technical effects of this technical solution compared with the prior art are as follows:

[0034] 1. In this technical solution, a fixing component is provided on the floating box. The fixing component includes at least one flexible connecting member. The flexible connecting member is bent and tightly wound around the pump body and firmly connected to the floating box, so that the pump body can be fixed under the floating box, ensuring the firm connection between the pump body and the floating box. Its flexibility improves the adaptability of the flexible connecting member to the fixation of different pump bodies, thereby making the versatility better. Description of the Drawings

Detailed Description of the Invention

[0041] The following further details the specific implementation manners of this technical solution with reference to the drawings.

[0042] Embodiment 1:

[0043] See Figure 1 and Figure 4, a floating pump, including a floating box 1, below which a pump body 10 is to be installed. The floating box 1 can float on the water surface. When it tends to a stable state, at this time the pump body 10 is completely immersed below the water surface plane and has a certain vertical distance from the water surface. It also includes a fixing component 2, which includes at least one flexible connecting piece 21. In this embodiment, the case where there are two flexible connecting pieces 21 is shown. The flexible connecting pieces 21 are all made of flexible materials, preferably ropes or steel wires. The two flexible connecting pieces 21 cooperate to fix the front and rear ends of the pump body 10 to the floating box 1 respectively, so that it is stably installed.

[0044] See Figure 2 and Figure 3 , a circulation groove 3 adapted to the shape of the upper part of the pump body 10 is formed on the lower end face of the floating box 1, and its groove direction is arranged corresponding to the length direction of the floating box 1. The pump body 10 can be correspondingly arranged at the circulation groove 3, so that the pump body 10 can be axially fixed relative to the circulation groove 3. When the floating box 1 and the pump body 10 are in a floating state, the lowest point of the bottom of the circulation groove 3 is lower than the water surface, and the circulation groove 3 provides a space for the drainage flow.

[0045] The floating box 1 is provided with a relief cavity 7, which is arranged in the middle of the floating box 1 and penetrates in the vertical direction, so that one end of the through end conducts to the bottom of the circulation groove 3, and the other end conducts to the upper end face of the floating box 1. When the pump body 10 is positioned, the relief cavity 7 is arranged corresponding to the water inlet of the pump body 10, further providing a space, and at the same time enabling the structure of the floating box 1 to be adjusted to stably float at the required water level height, avoiding the situation of air suction of the pump body 10 (the pump body 10 is exposed above the water surface or too close to the water surface, resulting in the simultaneous absorption of air and water).

[0046] Handling grooves are formed on the side wall of the floating box 1. There are two handling grooves, and the two handling grooves are correspondingly arranged on the opposite sides of the floating box 1 along the groove direction of the circulation groove 3 and are symmetrically arranged, and the groove openings face outwards. Each side of the handling groove specifically includes a first handling groove 5 and a second handling groove 6. The groove directions of the first handling groove 5 and the second handling groove 6 are coaxial. In this embodiment, the groove length of the first handling groove 5 shown is greater than that of the second handling groove 6. The floating box 1 is provided with a plurality of through holes 4, and the plurality of through holes 4 are correspondingly opened on the opposite sides of the floating box 1 along the length direction of the pump body 10, and the connecting holes on both sides are symmetrically arranged. Among them, four through holes 4 penetrate through the lower side wall of each first handling groove 5, and the four through holes 4 are arranged at intervals along the groove direction. At least one through hole 4 penetrates through the lower side wall of each second handling groove 6, and the through holes 4 are for the flexible connecting piece 21 to pass through.

[0047] The two flexible connectors 21 can be respectively inserted into the corresponding through holes 4 in the first handling groove 5 and the second handling groove 6. Each flexible connector 21 is bent and formed with a first pipe section 211 and a second ring section 212. The first pipe section 211 is located outside the second ring section 212. The first pipe section 211 and the second ring section 212 are connected as a whole. The second ring section 212 is wound around the pump body 10. The first pipe section 211 is inserted into the through holes 4 on both sides, and forms a support for the side of the pump body 10 facing away from the floating box 1. Tighten the flexible connector 21 to reduce the redundant swinging space, so that the pump body 10 and the floating box 1 are relatively fixed and maintain a stable position.

[0048] A groove 8 is also provided on the side wall of the floating box 1. The groove 8 is located at one end side wall of the floating box 1 along the length direction and is arranged relatively close to the second handling groove 6 in position. A connection hole 9 penetrates through the inner wall of the groove 8. When a flexible connector 21 binds around the pump body 10 for one circle, its two ends pass through the connection hole 9 opened on the lower end surface of the groove 8 into the groove 8 together, and then pass through the connection hole 9 opened on the upper end surface of the groove 8 to the upper end surface of the floating box 1, and are fixed after being connected by a connector. The connector is preferably a U-shaped connector to fix the end. Alternatively, the two ends of the flexible connector 21 can also be tied in a knot to achieve fixation, and the size of the knot is larger than the size of the connection hole 9.

[0049] The specific working process of this solution is as follows:

[0050] In this technical solution, the two flexible connectors 21 are wound around both ends of the pump body 10, and both flexible connectors 21 pass through the through holes 4 on both sides of the floating box 1, so that the pump body 10 is stably fixed below the floating box 1. The floating box 1 can drive the pump body 10 to float on the water surface together. When its floating tends to a stable state, the pump body 10 is completely immersed below the water surface and maintains a certain distance from the water surface, and is placed at a suitable position in the water to avoid the occurrence of air suction. The flexible connector 21 ensures the firm connection between the pump body 10 and the floating box 1, and its flexibility improves the adaptability of the flexible connector 21 to the fixation of different pump bodies 10, thus making the versatility better.

[0051] Embodiment 2:

[0052] See Figure 5 , a floating pump, the difference from Embodiment 1 is that the fixing assembly 2 further includes two metal connectors 22. The two metal connectors 22 are respectively tightened around both ends of the pump body 10. Both ends of each metal connector 22 can be fixed on both sides of the lower end surface of the floating box 1 through bolts, so as to realize the fixed positioning of the pump body 10, and can cooperate with the flexible connector 21 to further enhance the fixing effect.
