Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of multi-stage pumps for sewage discharge, and in particular relates to a multi-stage pump for sewage discharge. Background Art
[0002] The multistage pump is a centrifugal pump that is composed of an inlet and outlet section and a middle section, which are connected by a tie rod. Its output water pressure can be very high, and it also relies on the rotation of the impeller to obtain centrifugal force. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, thus gradually obtaining a high vacuum.
[0003] At present, in the existing technology, such as CN202121849972.X, most of the multi-stage pumps still have unstable connections due to vibration when connected to the pipeline. Long-term use will cause water seepage at the connection, resulting in liquid overflow in the pipeline. Therefore, in order to avoid the unstable connection between the multi-stage pump and the pipeline and liquid overflow. Utility Model Content
[0004] In view of the problems in the related technology, the utility model proposes a multi-stage pump for sewage discharge to overcome the above technical problems existing in the existing related technology.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a multi-stage pump for sewage discharge, comprising a base, a sliding box is arranged at the middle end of the base, a rotating block is arranged at one end of the sliding box, a rotating rod is arranged at one end of the rotating block, a rotating screw is arranged at the other end of the rotating rod, a sliding plate is arranged outside the rotating screw, the sliding plate is threadedly connected with the rotating screw, a wrapping plate is arranged at the upper end of the sliding plate, shock-absorbing cotton is arranged at one end of the wrapping plate, and a waterproof strip is arranged at the other end of the shock-absorbing cotton.
[0007] Furthermore, a thread groove is provided inside the sliding plate, the thread groove is threadedly connected to the rotating screw, a stabilizing block is provided on one side of the outside of the sliding plate, sliding grooves are provided on both sides of the sliding box, and the stabilizing block is slidably matched with the sliding groove.
[0008] Furthermore, a damping pad is arranged on one side of the upper end of the base, a mounting plate is arranged outside the damping pad, and a water pump is arranged on the upper end of the mounting plate.
[0009] Furthermore, an output pipe is provided at one end of the water pump, and a connection port is provided at the other end of the output pipe. A flange connection port is designed outside the connection port, a fixing port is provided inside the flange connection port, and a waterproof strip is provided outside the fixing port.
[0010] Furthermore, a dividing portion is provided at the middle end of the rotating screw rod, a forward threaded rod is provided on one side of the dividing portion, and a reverse threaded rod is provided on the other side of the dividing portion.
[0011] Furthermore, the other end of the flange connection port at one end of the water pump is connected to the water inlet pipe at one end of the multi-stage pump so that the two can work more stably after being connected.
[0012] The utility model has the following beneficial effects: when it is necessary to wrap the connection, a rotating block at one end of the sliding box at the middle end of the base is twisted, and when the rotating block is twisted, the rotating rod at one end is driven to rotate, and when the rotating rod is rotated, the rotating screw rod at the other end is driven to rotate, and when the rotating screw rod rotates, it is threadedly connected with the external sliding plate, so that the rotating screw rod rotates and drives the sliding plate to move inward, and when the sliding plate moves inward, it drives the wrapping plate at the upper end to move inward, and when the wrapping plate moves inward, it drives the waterproof strip to wrap the connection so that water cannot overflow during work, and the vibration generated during work is damped by the shock-absorbing cotton at the middle position of the waterproof strip and the wrapping plate, thereby greatly increasing the usability of the equipment, and the sliding plate is threadedly connected with the rotating screw rod through a threaded groove, so that when the rotating screw rod rotates, it drives the sliding plate to move left and right, and when the sliding plate moves left and right, the stabilizing block on one side slides with the sliding grooves on both sides of the sliding box, so that the sliding plate is more stable when moving and will not flip or deviate to wrap the connection, and the vibration generated when the water pump is working is transmitted downward to the mounting plate at the lower end, and the mounting plate transmits the vibration to the lower mounting plate. The vibration is transmitted to the base at the lower end, and the damping pad between the base and the mounting plate alleviates the vibration transmitted by the mounting plate. When the water pump needs to be connected and installed with other equipment during operation, the connection port at the other end of the output pipe at one end of the water pump is connected and aligned with other equipment. After the connection port is aligned with other equipment, the flange connection port outside the connection port is fixedly connected to the fixed port inside the connection port to connect with other equipment. After the connection is completed, the connection port is wrapped by the waterproof strip outside the fixed port so that no water will seep out during operation to ensure work efficiency. The split at the middle end of the rotating screw ensures that the sliding plates at both ends will not move to the split to collide and cause the wrapping position to be wrong. When the positive threaded rod on one side of the split rotates forward, the external sliding plate moves inward, and when the reverse threaded rod on the other side of the split rotates forward, the external sliding plate moves inward, so that the rotating screw wraps the connection port when it rotates forward, and releases the wrapping of the connection port when the rotating screw rotates reversely. The other end of the flange connection port at one end of the water pump is connected to the water inlet pipe at one end of the multi-stage pump, so that the two work more stably after connection.
[0013] Through the above technical solution, 1. When the multi-stage pump is connected to a water pump or other equipment, it only needs to align the connection ports at both ends for connection and installation. The connection ports are fixed by rotating the screw rod, making the internal operation more stable.
[0014] 2. When working internally, vibration will be generated, and the shock-absorbing cotton wrapped inside the connection port can effectively reduce the vibration of the working equipment interface so that there will be no gap in the interface to allow the internal water to flow out. The waterproof strip at one end of the shock-absorbing cotton fits the gap of the connection port so that water will not seep out and the work can be completed better.
[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-4 As shown, the utility model is a multi-stage pump for sewage discharge, including a base 1, a sliding box 2 is arranged at the middle end of the base 1, a rotating block 3 is arranged at one end of the sliding box 2, a rotating rod 4 is arranged at one end of the rotating block 3, a rotating screw 5 is arranged at the other end of the rotating rod 4, a sliding plate 6 is arranged outside the rotating screw 5, the sliding plate 6 is threadedly connected with the rotating screw 5, a wrapping plate 7 is arranged at the upper end of the sliding plate 6, a shock-absorbing cotton 8 is arranged at one end of the wrapping plate 7, and a waterproof strip 9 is arranged at the other end of the shock-absorbing cotton 8.
[0026] According to the above, when the connection needs to be wrapped, the rotating block 3 at one end of the sliding box 2 at the middle end of the base 1 is twisted. When the rotating block 3 is twisted, the rotating rod 4 at one end is driven to rotate. When the rotating rod 4 rotates, it drives the rotating screw 5 at the other end to rotate. When the rotating screw 5 rotates, it is threadedly connected with the external sliding plate 6, so that the rotating screw 5 rotates and drives the sliding plate 6 to move inward. When the sliding plate 6 moves inward, it drives the upper end of the wrapping plate 7 to move inward. When the wrapping plate 7 moves inward, it drives the waterproof strip 9 to wrap the connection so that water cannot overflow during operation. The vibration generated during operation is damped by the shock-absorbing cotton 8 in the middle of the waterproof strip 9 and the wrapping plate 7, thereby greatly increasing the usability of the equipment.
[0027] In one embodiment, for the above-mentioned sliding plate 6, a thread groove 10 is provided inside the sliding plate 6, and the thread groove 10 is threadedly connected to the rotating screw 5. A stabilizing block 11 is provided on one side of the outside of the sliding plate 6, and sliding grooves 12 are provided on both sides of the sliding box 2. The stabilizing block 11 is slidably matched with the sliding grooves 12.
[0028] According to the above-mentioned sliding plate 6, the threaded connection with the rotating screw 5 is performed through the threaded groove 10, so that when the rotating screw 5 rotates, the sliding plate 6 is driven to move left and right. When the sliding plate 6 moves left and right, the stabilizing block 11 on one side slides with the sliding grooves 12 on both sides of the sliding box 2, so that the sliding plate 6 is more stable when moving and will not reverse or deviate to wrap the connection.

[0030] According to the above, when the water pump 15 is working, the vibration generated is transmitted downward to the mounting plate 14 at the lower end, and the mounting plate 14 transmits the transmitted vibration to the base 1 at the lower end. The damping pad 13 between the base 1 and the mounting plate 14 alleviates the vibration transmitted by the mounting plate 14.
[0031] In one embodiment, for the water pump 15, an output pipe 16 is provided at one end of the water pump 15, and a connection port 17 is provided at the other end of the output pipe 16.

[0032] When the water pump 15 needs to be connected and installed with other equipment during operation, the output pipe 16 at one end of the water pump 15 is connected and aligned with the other equipment through the connection port 17 at the other end. After the connection port 17 is aligned with the other equipment, the flange connection port 18 outside the connection port 17 is fixedly connected with the fixing port 19 inside to connect with the other equipment.

[0034] According to the division 22 at the middle end of the rotating screw rod 5, it is ensured that the sliding plates 6 at both ends will not move to the division 22 to collide and cause the wrapping position to be wrong. When the forward threaded rod 23 on one side of the division 22 rotates forward, the outer sliding plate 6 moves inward, and when the reverse threaded rod 24 on the other side of the division 22 rotates forward, the outer sliding plate 6 moves inward, so that the rotating screw rod 5 wraps the connecting port 17 when it rotates forward, and releases the wrapping of the connecting port 17 when the rotating screw rod 5 rotates reversely.

The connection is wrapped, and the vibration generated when the water pump 15 is working is transmitted downward to the mounting plate 14 at the lower end, and the mounting plate 14 transmits the transmitted vibration to the lower end The base 1 is used for transmission, and the damping pad 13 between the base 1 and the mounting plate 14 alleviates the vibration transmitted by the mounting plate 14. When the water pump 15 needs to be connected and installed with other equipment during operation, the output pipe 16 at one end of the water pump 15 is connected and aligned with other equipment through the connecting port 17 at the other end. After the connecting port 17 is aligned with other equipment, the fixing port 19 inside the flange connecting port 18 outside the connecting port 17 is fixedly connected to connect with other equipment. After the connection is completed, the waterproof strip 9 outside the fixing port 19 is used to wrap the connecting port 17 so that no water will seep out during operation to ensure work efficiency. The dividing part 22 at the middle end of the rotating screw rod 5 ensures that the sliding plates 6 at both ends will not move to the dividing part 22 to collide and cause the wrapping position to be wrong. When the forward threaded rod 23 on one side of the dividing part 22 rotates forward, the outer sliding plate 6 moves inward, and when the reverse threaded rod 24 on the other side of the dividing part 22 rotates forward, the outer sliding plate 6 moves inward, so that the rotating screw rod 5 wraps the connecting port 17 when it rotates forward, and releases the wrapping of the connecting port 17 when the rotating screw rod 5 rotates reversely. The other end of the flange connecting port 18 at one end of the water pump 15 is connected to the water inlet pipe 20 at one end of the multi-stage pump 21, so that the two can work more stably after being connected.
[0038] Through the above technical solution, 1.
