The housing is provided with a second water inlet 141 and a second water outlet 142 perpendicular to each other. The wheel shaft passes through the housing. The impeller is provided on the portion of the wheel shaft located inside the housing. The second gear 143 is provided on the portion of the wheel shaft located outside the housing. The first gear 113 and the second gear 143 are meshed. The heating device 2 includes a heating body 21, a circulation pump 22 and a heat exchanger 23. The heating body 21 includes a third water inlet and a third water outlet. The heat exchanger 23 includes a liquid inlet main pipe 231, a liquid outlet main pipe 232 and a plurality of heat exchange sleeves 233. The plurality of heat exchange sleeves 233 are sealed and sleeved on the outer periphery of the heat exchange pipe 12 and there are intervals between the plurality of heat exchange sleeves 233. The heat exchange sleeves 233 include an inlet 2331 and an outlet 2332. The inlet 2331 is connected to the liquid inlet main pipe 231, and the outlet 2332 is connected to the liquid outlet main pipe 232. The liquid outlet main pipe 232 is connected to the second water inlet 141, and the second water outlet 142 is connected to the third water inlet through the circulation pump 22. The third water outlet is connected to the liquid inlet main pipe 231 through the bending pipe 4 to form a heat cycle, and there is a circulating liquid in the heat cycle. When the energy-saving water pump 1 is working, the circulating pump 22 is started synchronously to start the heat cycle and the cooling water cycle; the heating device 2 heats the circulating liquid, and the circulating liquid intermittently heats the heat exchange pipe 12 through multiple heat exchange sleeves 233 to form staggered cold zones 121 and hot zones 122. In the hot zone 122, the cooling medium in the heat exchange pipe 12 is evenly heated, so that the dissolved air is precipitated and forms an air film on the inner wall of the heat exchange pipe 12 when flowing through the cold zone 121 under the action of the flow of the cooling medium, so that the resistance between the cooling medium and the inner wall is reduced when passing through the inner wall of the cold zone 121; in the cold zone 121, the air film is destroyed due to the temperature change of the cooling medium, and contacts with the inner wall when flowing through the hot zone 122 under the action of the flow of the cooling medium to enhance the heat exchange effect; after the circulating liquid is cooled through the heat exchange pipe 12, it passes through the liquid outlet main pipe 232 and impacts the impeller under the action of gravitational potential energy to drive the first gear 113 to rotate, and then drives the pump shaft of the pump machine 11 to do work.

[0018] From the above description, it can be known that by setting the pump 11, the vertical heat exchange pipe 12 and the multiple heat exchange sleeves 233, the heat exchange pipe 12 is intermittently heated to form staggered cold zones 121 and hot zones 122. In the hot zone 122, the vertical heat exchange pipe 12 can form an air film on the inner wall of the cooling heat exchange pipe 12 (because the formation of the air film requires time and combined with the flow rate of the cooling medium, the air film in the hot zone 122 can be completely formed in the cold zone 121). In addition, the heat exchange pipe 12 is a round tube. When the gravity is downward and the buoyancy is upward, the air film is combined with the round tube to ensure that the pressure on the same section of the inner wall of the heat exchange pipe 12 is uniform, thereby forming a uniform air film. The uniform air film can reduce the resistance of the cooling medium, thereby reducing the power consumption of the pump 11, and achieving energy saving. Furthermore, since the existing heating body 21, such as various high The furnace and the refining tower are originally arranged vertically, and the circulating pump 22 of the heat pump body itself needs to overcome the gravitational potential energy. This part of energy is wasted in the existing method, and through the engagement of the first gear 113 and the second gear 143, the wasted gravitational potential energy can be reused as the energy source of the pump 11, thereby achieving secondary energy saving. At the same time, since the gravitational potential energy is utilized, the pressure difference inside the pipeline in the heat cycle tends to be balanced, thereby avoiding the gravitational impact of the coolant causing the impact of the circulating pump 22, and further extending the service life of the circulating pump 22; the first water inlet 111 is connected to the cooling tower 13 through the bent pipe 4, and there is only one bend in the cooling water circulation. The other bends are realized through the structural design of each equipment itself, which can greatly reduce the bends in the cooling water circulation, thereby reducing the chance of forming turbulence and turbulence, thereby achieving drag reduction, and thereby achieving tertiary energy saving.

[0019] Furthermore, with the lowest point of the heat exchange pipe 12 as the starting point and the highest point as the end point, when the staggered cold zone 121 and hot zone 122 are arranged, the hot zone 122 is the starting point and the cold zone 121 is the end point.

[0020] From the above description, it can be seen that by using the hot zone 122 as the lowest starting point and the highest end point, it can be ensured that the subsequent heat exchange pipe 12 can form bubbles in the interlacing. At the same time, the cold zone 121 is set at the end point, which can ensure that there are no bubbles on the inner wall of the subsequent bent pipe, avoiding aggravating turbulence or turbulence at the bend.

[0021] Furthermore, the number of inlets 2331 of the heat exchange sleeve 233 is greater than or equal to two.

[0022] From the above description, it can be seen that by having more than or equal to two inlets 2331, the contact area between the cooling water and the heat exchange pipe 12 can be guaranteed. Since the heat exchange pipe 12 is circular, uniform heating can be achieved.

[0023] Furthermore, the inlet 2331 and the outlet 2332 of the heat exchange sleeve 233 are distributed in a circular array.

[0024] From the above description, it can be seen that the circular array arrangement can further ensure uniform heating.

[0025] Furthermore, the inlet 2331 and the outlet 2332 of the heat exchange sleeve 233 are arranged at an angle, and the inlet 2331 and the outlet 2332 are inclined in opposite directions.

[0026] It can be seen from the above description that the inclined inlet 2331 and outlet 2332 can increase the flow rate and ensure rapid heat exchange.

[0027] Furthermore, a plurality of heat exchange thin rings 123 are arranged on the surface of the hot zone 122 corresponding to the heat exchange pipe 12 .

[0028] It can be seen from the above description that the heat exchange effect can be improved by using the heat exchange thin ring 123.

[0029] Furthermore, the energy-saving water pump 1 further comprises a clutch 5, a controller and an impact sensor, the pump 11, the clutch 5 and the impact sensor are electrically connected to the controller respectively, and the first gear 113 and the second gear 143 are connected through the clutch 5; The impact sensor is disposed in the second water inlet 141 , and the controller determines the impact power according to the impact sensor. If the impact power is greater than a preset value, the controller controls the clutch 5 to separate the first gear 113 and the second gear 143 .

[0030] It can be seen from the above description that the clutch 5 can prevent the water pump from being subjected to excessive impact, thereby ensuring the service life of the water pump.

[0031] Furthermore, the energy-saving water pump 1 further comprises a battery and a generator 6, wherein the battery and the generator 6 are electrically connected to the controller respectively; the generator 6 has a third gear 61, and the first gear 113 and the third gear 61 are connected via a clutch 5; If the impact power is greater than the preset value, the controller controls the clutch 5 to separate the first gear 113 and the second gear 143 and mesh with the third gear 61 to input kinetic energy to the generator 6. The electrical energy generated by the generator 6 enters the battery through the controller or is directly supplied to the water pump for use.

[0032] From the above description, it can be seen that in actual production, the water pressure of cooling water is not too constant, but has certain fluctuations. Through the generator 6, the impact that the water pump cannot withstand can be absorbed and generated to supply the water pump, thereby achieving four times energy saving.

[0033] Furthermore, the first gear 113, the second gear 143, the third gear 61 and the clutch 5 are arranged in the same protective shell.

[0034] Furthermore, the straight tube 3 and the bent tube 4 are provided with heat dissipation fins.

[0035] From the above description, it can be seen that through the heat dissipation fins, heat dissipation can be carried out synchronously in the pipeline, thereby improving the heat dissipation effect and reducing the water pump load.
