[0024] The above scheme is adopted: by setting the base plate 1, pump body 2, motor 3, frequency conversion component 4, water inlet pipe 5, water outlet pipe 6, heat dissipation mechanism 7 and silencer mechanism 8, when in use, the base plate 1 can fix the pump body 2 and the motor 3 on the ground, and then the water inlet pipe 5 and the water outlet pipe 6 are set on the pump body 2, the water inlet pipe 5 and the water outlet pipe 6 have the same diameter and are located at the same height, the frequency conversion component 4 can adjust the running speed of the pump body 2, and can flexibly adjust the running speed and power output of the pump body 2 according to actual needs. By adjusting the running speed of the pump body 2 according to the requirements of the pipeline system, energy waste can be avoided and the efficiency of the entire system can be improved. Among them, the heat dissipation mechanism 7 can dissipate the heat of the motor 3, and then during the operation, the noise source is mainly the background noise of the motor 3, and the background noise of the motor 3 can be silenced by the silencer mechanism 8.

[0025] refer to Figure 5 The heat dissipation mechanism 7 includes a protective cover 701, a heat dissipation fan 702 and a fixing bolt 703. The protective cover 701 is arranged on the outside of the motor 3, the heat dissipation fan 702 is arranged on the upper surface of the protective cover 701, the fixing bolt 703 is arranged at the lower end of the protective cover 701, and the protective cover 701 is arranged on the pump body 2 through the fixing bolt 703.

[0026] The above scheme is adopted: by setting a protective cover 701, a heat dissipation fan 702 and a fixing bolt 703, when in use, the protective cover 701 is fixed to the pump body 2 by the fixing bolt 703, and the motor 3 is located inside the protective cover 701, which can protect the motor 3. When the motor 3 is running, a high amount of heat will be generated inside the protective cover 701. At this time, the heat dissipation fan 702 is turned on, and the cold air from the outside is transmitted to the inside of the protective cover 701 through the heat dissipation fan 702, so as to dissipate heat and cool the motor 3.

[0027] refer to Figure 6 The silencer mechanism 8 includes a first silencer plate 801, a second silencer plate 802 and a silencer channel 803. The first silencer plate 801 is arranged on the side wall of the motor 3, the second silencer plate 802 is arranged on one side of the first silencer plate 801, and the silencer channel 803 is arranged between the first silencer plate 801 and the second silencer plate 802.

[0028] The above scheme is adopted: by setting the first sound-absorbing plate 801, the second sound-absorbing plate 802 and the sound-absorbing channel 803, when the motor 3 is working, it is easy to generate noise, and the first sound-absorbing plate 801 and the second sound-absorbing plate 802 can absorb the noise. When the noise passes through the first sound-absorbing plate 801 and enters the sound-absorbing channel 803, the structural setting of the sound-absorbing channel 803 can make the noise be absorbed in the sound-absorbing channel 803, thereby further improving the sound-absorbing effect.

[0029] refer to Figure 1The outer wall of the protective cover 701 is provided with heat dissipation grooves 9, which are arranged obliquely downward. There are a plurality of heat dissipation grooves 9 which are arranged in a circle.

[0030] The above scheme is adopted: by setting the heat dissipation groove 9, when the heat dissipation fan 702 allows the cold air from the outside to enter the protective cover 701, the air pressure of the protective cover 701 will increase. At this time, the hot air inside the protective cover 701 can be discharged through the heat dissipation groove 9, further achieving the effect of heat dissipation and protecting the motor 3.

[0031] refer to Figure 6 A first heat dissipation channel 10 is arranged on the first muffler plate 801, and a second heat dissipation channel 11 is arranged on the second muffler plate 802. The first heat dissipation channel 10 and the second heat dissipation channel 11 are arranged crosswise.

[0032] The above scheme is adopted: by setting the first heat dissipation channel 10 and the second heat dissipation channel 11, since the first silencer plate 801 is directly wrapped on the outer wall of the motor 3, the first heat dissipation channel 10 and the second heat dissipation channel 11 can discharge the heat generated by the motor 3, and then the first heat dissipation channel 10 and the second heat dissipation channel 11 are cross-arranged to form a silencer channel 803, which can better silence the noise generated by the motor 3.

[0033] refer to Figure 1 The bottom plate 1 is provided with fixing holes 12, and the number of the fixing holes 12 is four and they are symmetrically arranged.

[0034] The above solution is adopted: by setting the fixing hole 12, when in use, the fixing hole 12 is set on the bottom plate 1, and the bottom plate 1 can be fixed on the ground through the fixing hole 12, thereby fixing the pump body 2 and the motor 3 on the ground.

[0035] The working principle of this utility model:

[0036] When in use, first, the fixing hole 12 is set on the bottom plate 1, and the bottom plate 1 can be fixed to the ground through the fixing hole 12, and then the pump body 2 and the motor 3 are fixed to the ground, and then the water inlet pipe 5 and the water outlet pipe 6 are set on the pump body 2, the water inlet pipe 5 and the water outlet pipe 6 have the same diameter and are located at the same height, the frequency conversion component 4 can adjust the running speed of the pump body 2, and can flexibly adjust the running speed and power output of the pump body 2 according to actual needs. By adjusting the running speed of the pump body 2 according to the needs of the pipeline system, energy waste can be avoided and the efficiency of the entire system can be improved. Then the protective cover 701 is fixed to the pump body 2 by the fixing bolts 703, and the motor 3 is located inside the protective cover 701, which can protect the motor 3. When the motor 3 is running, a higher Heat, at this time, turn on the heat dissipation fan 702, and transmit the external cold air to the inside of the protective cover 701 through the heat dissipation fan 702, so as to dissipate heat and cool the motor 3. When the heat dissipation fan 702 allows the external cold air to enter the protective cover 701, the air pressure of the protective cover 701 will increase. At this time, the hot air inside the protective cover 701 can be discharged through the heat dissipation slot 9, so as to further achieve the effect of heat dissipation and protect the motor 3. Then, when the motor 3 is working, it is easy to generate noise, and the noise can be absorbed by the first silencer plate 801 and the second silencer plate 802. When the noise passes through the first silencer plate 801 and enters the silencer channel 803, the noise can be absorbed in the silencer channel 803 through the structural setting of the silencer channel 803, so as to further improve the silencer effect.
