Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, in particular to a cooling device for a central air-conditioning water circulation pump. Background Art

[0002] As large public buildings with large passenger flows and expansive spaces, airports place high demands on their indoor environment. Integrated central air conditioning systems can provide stable and uniform cooling or heating for large areas, ensuring that environmental parameters such as temperature and humidity remain within appropriate ranges across the airport. The central air conditioning water circulation pump within the integrated air conditioning unit primarily transports coolant from the central unit to various sub-units, thereby providing a warm or cool indoor environment. However, the water pump motor can become hot over extended periods of operation and can burn out if not cooled promptly.

[0003] For example, in the prior art disclosed in publication number CN220648568U, the device in this scheme absorbs the heat emitted by the motor of the water circulation pump by arranging a left heat-conducting housing, a right heat-conducting housing, and a heat sink. The left and right heat-conducting housings are connected to the water inlet and outlet of the water circulation pump through a shunt pipe and a header. The water flowing through the left and right heat-conducting housings continuously removes the heat from the heat-conducting housings and the heat sink.

[0004] During the operation of the existing water circulation pump, a small amount of water is likely to leak from the connection between the water circulation pump and the pipeline. The water will accumulate in the dead corner between the water circulation pump motor and the heat dissipation fins, which is difficult to effectively clean and easily causes corrosion to the water circulation pump. At the same time, the water circulation pump needs to be preheated before operation. The existing preheating method is to gradually increase the speed and flow rate to make the water circulation pump reach the predetermined operating temperature. However, there is a temperature difference between the outside and inside of the water circulation pump, and it takes more time and energy to make the outside of the water circulation pump reach the predetermined temperature. Summary of the Invention

[0005] The technical problems solved by this solution are:

[0006] (1) How to solve the problem that water accumulates in the dead corner between the water circulation pump motor and the heat dissipation fins, making it difficult to effectively clean it and easily causing corrosion to the water circulation pump;

[0007] (2) How to solve the problem that the existing preheating method is to heat the inside of the water circulation pump, while there is a temperature difference between the outside and inside of the water circulation pump, and it takes more time and energy to make the outside of the water circulation pump reach the predetermined temperature.

[0008] The object of the present invention can be achieved by the following technical solution: A central air-conditioning water circulation pump cooling device includes a base, a heat preservation cover is fixedly installed on one side of the top of the base, and a water circulation pump is placed on the other side of the top of the base, one end of the water circulation pump is located at the opening of the heat preservation cover, a cooling mechanism for cooling the water circulation pump is provided inside the heat preservation cover, and a heating mechanism for preheating the water circulation pump is provided on one side of the cooling mechanism;

[0009] The cooling mechanism includes a heat-conducting sleeve, which is arranged horizontally. A heat-conducting box is fixedly installed on the side of the inner wall of the heat-conducting sleeve away from the water circulation pump. The top of the heat-conducting box is connected to a return hose, and the bottom of the heat-conducting box is connected to a water inlet hose.

[0010] A further technical improvement of the present invention is that a water tank is provided on the top of the thermal insulation cover, a water pump is fixedly installed on the front of the water tank, the input end of the water inlet hose passes through the thermal insulation cover and is connected to the output end of the water pump, and the output end of the return water hose passes through the thermal insulation cover and is connected to the top of the water tank.

[0011] A further technical improvement of the present invention is that an L-shaped rod is rotatably provided on the inner wall of the heat-insulating cover above the heat-conducting sleeve, a fan is fixedly installed on one end of the L-shaped rod, a horizontally arranged cylinder is also fixedly installed on the inner wall of the heat-insulating cover, the protruding end of the cylinder is fixedly connected to the heat-conducting sleeve, and a pushing wheel is rotatably provided on the protruding end of the cylinder, and the pushing wheel is rollingly connected to the L-shaped rod.

[0012] A further technical improvement of the present invention is that: the inner wall size of the heat-conducting sleeve corresponds to the size of the water circulation pump, and sliders are fixedly installed on the front and rear outer walls of the heat-conducting sleeve, and slide grooves are provided on the front and rear inner walls of the heat-insulating cover, and the two sliders are slidably connected with the corresponding slide grooves respectively. The bottom of the inner wall of the heat-conducting sleeve is also rotatably provided with a plurality of rollers, and the rollers are rollingly connected with the base; by controlling the extended end of the cylinder to extend to the longest, the heat dissipation fins of the water circulation pump motor are completely located in the heat-conducting sleeve. At this time, the heat-conducting box contacts the side wall of the water circulation pump motor, and the clean water in the water tank is injected into the heat-conducting box through the water inlet hose by the water pump, and the clean water passing through the heat-conducting box is collected back into the water tank through the return hose. The clean water passing through the heat-conducting box will cooperate with the heat-conducting box to pump the water circulation pump motor on the side wall. The heat is taken away, thereby playing the role of cooling the water circulation pump. At the same time, when the extended end of the cylinder is extended to its longest, the push wheel rolls to a section of the L-shaped rod away from the fan. During this process, the fan does not move, and the moving wheel rolls to the end of the L-shaped frame away from the shift rod. During this process, the L-shaped frame rotates, so that the blocking block cooperates with the sealing plate to move downward, blocking the second air vent to prevent the residual heat therein from affecting the efficiency of cooling the water circulation pump. The surface of the water circulation pump is cooled by the heat conductive sleeve and the heat dissipation fins in contact with it. At the same time, the airflow blown out by the fan passes through between the heat dissipation fins, quickly drying the moisture accumulated in the dead corner between the water circulation pump motor and the heat dissipation fins, avoiding corrosion to the water circulation pump, extending the service life of the water circulation pump, and thus reducing energy consumption.

[0013] A further technical improvement of the present invention is that the heating mechanism includes a mounting plate fixedly connected to the heat preservation cover, a longitudinally arranged guide rod is fixedly connected between the mounting plate and the base, the outer wall sliding sleeve of the guide rod is provided with a blocking block, and the blocking block is slidably connected to the inner wall of the heat preservation cover.

[0014] A further technical improvement of the present invention is that a first air vent and a second air vent are provided on the inner wall of the heat-insulating cover below the mounting plate, a plurality of electric heating wires are fixedly installed on the inner wall of the second air vent, a sealing plate is fixedly embedded on the side wall of the shielding block away from the heat-conducting sleeve, and the sizes of the first air vent and the second air vent are both smaller than the sizes of the sealing plate.

[0015] The further technical improvement of the present invention is that an L-shaped frame is rotatably connected to the inner wall of the heat-insulating cover between the blocking block and the heat-conducting sleeve, and an adjustment slot is provided at one end of the L-shaped frame. The back side of the blocking block is slidably connected to the adjustment slot via a lever; by controlling the extended end of the cylinder to extend from the shortest to half the length, the heat-conducting sleeve is pushed to move so that one end of the inner wall of the heat-conducting sleeve contacts the heat dissipation fins of the water circulation pump motor. At this time, the driving wheel rolls from a section of the L-shaped rod close to the fan to the middle thereof. Due to the influence of gravity, the L-shaped rod flips over, so that the fan is set toward the inner wall of the heat-conducting sleeve. At the same time, the moving wheel is moved from the end of the L-shaped frame close to the lever The first air vent is blocked by the blocking block and the sealing plate. As the electric heating wires in the second air vent heat the airflow entering the heat preservation cover, the fan injects the hot air flow into the heat conductive sleeve. While the hot air flows through the heat dissipation fins, the heat of the hot air flow is transferred to the surface of the water circulation pump. The heat preservation cover is used to prevent the heat from dissipating quickly, reduce the energy consumption of heating the surface of the water circulation pump, assist in the internal preheating of the water circulation pump itself, avoid the temperature difference between the outside and the inside of the water circulation pump, and speed up the preheating of the water circulation pump, thereby further reducing energy consumption.

[0016] A further technical improvement of the present invention is that: one end of the heat-conducting sleeve facing the shielding block is fixedly connected to a support frame, one end of the support frame is rotatably provided with a moving wheel, and the moving wheel is rollingly connected to the L-shaped frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the present invention is in use, the extended end of the cylinder is controlled to extend to the longest position, so that the heat dissipation fins of the water circulation pump motor are completely located in the heat-conducting sleeve. At this time, the heat-conducting box contacts the side wall of the water circulation pump motor, and the clean water in the water tank is injected into the heat-conducting box through the water inlet hose by the water pump, and the clean water passing through the heat-conducting box is collected back into the water tank through the return hose. The clean water passing through the heat-conducting box will cooperate with the heat-conducting box to take away the heat on the side wall of the water circulation pump motor, thereby playing a role in cooling the water circulation pump. At the same time, when the extended end of the cylinder is extended to the longest position, the push wheel rolls to a section of the L-shaped rod away from the fan, and the process During the process, the fan does not move, and the moving wheel rolls to the end of the L-shaped frame away from the lever. During this process, the L-shaped frame rotates, causing the blocking block to move downward in conjunction with the sealing plate to block the second air vent to prevent the residual heat therein from affecting the efficiency of cooling the water circulation pump. The surface of the water circulation pump is cooled by the heat conductive sleeve and the heat dissipation fins in contact with it. At the same time, the air flow blown out by the fan passes through between the heat dissipation fins, quickly drying the moisture accumulated in the dead corner between the water circulation pump motor and the heat dissipation fins, thereby avoiding corrosion to the water circulation pump, extending the service life of the water circulation pump, and reducing energy consumption.

[0019] When the air flow is in the air-conditioning system, the air conditioner is in a state of being heated and cooled, and the air flow is gradually cooled, and the air conditioner is cooled and cooled. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 2 and Figure 3As shown, the inner wall size of the above-mentioned heat-conducting sleeve 96 corresponds to the size of the water circulation pump 4, and sliders are fixedly installed on the front and rear outer walls of the heat-conducting sleeve 96, and slide grooves are opened on the front and rear inner walls of the heat-insulating cover 5. The two sliders are slidably connected with the corresponding slide grooves respectively. The bottom of the inner wall of the heat-conducting sleeve 96 is also rotatably provided with a plurality of rollers 94, and the rollers 94 are rollingly connected with the base 3; by controlling the extended end of the cylinder 91 to be extended to the longest, the heat dissipation fins of the water circulation pump 4 motor are completely located in the heat-conducting sleeve 96. At this time, the heat-conducting box 95 contacts the side wall of the water circulation pump 4 motor, and the clean water in the water tank 1 is injected into the heat-conducting box 95 through the water pump 2 through the water inlet hose 93, and then the clean water passing through the heat-conducting box 95 is collected back into the water tank 1 through the return hose 99. The clean water passing through the heat-conducting box 95 will cooperate with the heat-conducting box 95 to take away the heat on the side wall of the water circulation pump 4 motor. Thereby, the water circulation pump 4 is cooled. At the same time, when the protruding end of the cylinder 91 is extended to its longest, the push wheel 98 rolls to a section of the L-shaped rod 97 away from the fan 92. During this process, the fan 92 does not move, and the moving wheel 62 rolls to the end of the L-shaped frame 64 away from the lever 67. During this process, the L-shaped frame 64 rotates, so that the blocking block 65 cooperates with the sealing plate to move downward, blocking the second air vent 8 to prevent the residual heat therein from affecting the efficiency of cooling the water circulation pump 4. The surface of the water circulation pump 4 is cooled by the heat conducting sleeve 96 and the heat dissipating fins in contact therewith. At the same time, the air flow blown out by the fan 92 passes through between the heat dissipating fins, quickly drying the moisture accumulated in the dead corner between the motor of the water circulation pump 4 and the heat dissipating fins, thereby avoiding corrosion to the water circulation pump 4, extending the service life of the water circulation pump 4, and reducing energy consumption.

[0034] See also Figure 2 and Figure 5 As shown, the above-mentioned heating mechanism 6 includes a mounting plate 66 fixedly connected to the heat preservation cover 5, and a longitudinally arranged guide rod 61 is fixedly connected between the mounting plate 66 and the base 3. The outer wall sliding sleeve of the guide rod 61 is provided with a blocking block 65, and the blocking block 65 is slidably connected to the inner wall of the heat preservation cover 5.

[0035] See also Figure 5 and Figure 6 As shown, a first air vent 7 and a second air vent 8 are provided on the inner wall of the heat-insulating cover 5 below the above-mentioned mounting plate 66, and a plurality of electric heating wires are fixedly installed on the inner wall of the second air vent 8. A sealing plate is fixedly embedded on the side wall of the blocking block 65 away from the heat-conducting sleeve 96, and the sizes of the first air vent 7 and the second air vent 8 are both smaller than the sizes of the sealing plate.

[0036] See also Figure 5 and Figure 6As shown, an L-shaped frame 64 is rotatably connected to the inner wall of the heat preservation cover 5 between the above-mentioned blocking block 65 and the heat-conducting sleeve 96, and an adjustment slot 68 is provided at one end of the L-shaped frame 64. The back of the blocking block 65 is slidably connected to the adjustment slot 68 through a lever 67; by controlling the extended end of the cylinder 91 to extend from the shortest to half the length, the heat-conducting sleeve 96 is pushed to move so that one end of the inner wall of the heat-conducting sleeve 96 contacts the heat dissipation fins of the water circulation pump 4 motor. At this time, the driving wheel 98 rolls from a section of the L-shaped rod 97 close to the fan 92 to the middle thereof. Due to the influence of gravity, the L-shaped rod 97 flips over, so that the fan 92 is set toward the inner wall of the heat-conducting sleeve 96. At the same time, the moving wheel 62 moves from the L-shaped frame 64 close to the fan 92. The end of the lever 67 rolls to its middle, the L-shaped frame 64 does not move, and the blocking block 65 cooperates with the sealing plate to block the first air vent 7. Since the several electric heating wires in the second air vent 8 heat the air flow entering the thermal insulation cover 5, the fan 92 injects the hot air flow into the thermal sleeve 96. While the hot air flow passes through the heat dissipation fins, the heat of the hot air flow is transferred to the surface of the water circulation pump 4. Cooperating with the thermal insulation cover 5, it prevents the heat from dissipating quickly, reduces the energy consumption of heating the surface of the water circulation pump 4, and assists the internal preheating of the water circulation pump 4 itself, avoids the temperature difference between the outside and the inside of the water circulation pump 4, and at the same time speeds up the preheating speed of the water circulation pump 4, further reducing energy consumption.

[0037] See also Figure 2 and Figure 5 As shown, one end of the heat-conducting sleeve 96 facing the shielding block 65 is fixedly connected to the support frame 63 , and one end of the support frame 63 is rotatably provided with a moving wheel 62 , and the moving wheel 62 is rollingly connected to the L-shaped frame 64 .

[0038] Working principle: When the present invention is used, first, Figure 2 and Figure 3 As shown, when the water circulation pump 4 is turned on for slow preheating, the fan 92 and several electric heating wires are turned on at the same time, and the extended end of the cylinder 91 is controlled to extend from the shortest length to half the length, pushing the heat-conducting sleeve 96 to move, so that one end of the inner wall of the heat-conducting sleeve 96 contacts the heat dissipation fins of the water circulation pump 4 motor. At this time, the driving wheel 98 rolls from a section of the L-shaped rod 97 close to the fan 92 to the middle of it. Due to the influence of gravity, the L-shaped rod 97 flips over, so that the fan 92 is set toward the inner wall of the heat-conducting sleeve 96. At the same time, as shown in FIG. Figure 3 and Figure 5As shown, the moving wheel 62 rolls from the end of the L-shaped frame 64 close to the shift rod 67 to the middle thereof, the L-shaped frame 64 does not move, and the blocking block 65 cooperates with the sealing plate to block the first air vent 7. Since the several electric heating wires in the second air vent 8 heat the airflow entering the heat-insulating cover 5, the fan 92 injects the hot air flow into the heat-conducting sleeve 96. While the hot air flow passes through between the heat dissipating fins, the heat of the hot air flow is transferred to the surface of the water circulation pump 4, cooperating with the heat-insulating cover 5 to prevent the heat from dissipating quickly, reducing the energy consumption of heating the surface of the water circulation pump 4, assisting the internal preheating of the water circulation pump 4 itself, avoiding the temperature difference between the outside and the inside of the water circulation pump 4, and at the same time accelerating the preheating speed of the water circulation pump 4, further reducing energy consumption; as shown Figure 3 、 Figure 5 and Figure 6 As shown, after the preheating of the water circulation pump 4 is completed, several electric heating wires are turned off in time, and the water pump 2 is turned on at the same time. When the water circulation pump 4 is working normally, the extended end of the control cylinder 91 is extended to the longest, as shown in FIG. Figure 2-Figure 4 As shown, the heat dissipation fins of the water circulation pump 4 motor are completely located in the heat-conducting sleeve 96. At this time, the heat-conducting box 95 is in contact with the side wall of the water circulation pump 4 motor. The clean water in the water tank 1 is injected into the heat-conducting box 95 through the water pump 2 through the water inlet hose 93, and then the clean water passing through the heat-conducting box 95 is collected back into the water tank 1 through the return hose 99. The clean water passing through the heat-conducting box 95 will cooperate with the heat-conducting box 95 to take away the heat on the side wall of the water circulation pump 4 motor, thereby playing a role in cooling the water circulation pump 4. At the same time, Figure 3 and Figure 5 As shown, when the protruding end of the cylinder 91 is extended to its longest length, the pushing wheel 98 rolls to a section of the L-shaped rod 97 away from the fan 92. During this process, the fan 92 does not move, and the moving wheel 62 rolls to the end of the L-shaped frame 64 away from the lever 67. During this process, the L-shaped frame 64 rotates, so that the blocking block 65 cooperates with the sealing plate to move downward, blocking the second air vent 8 to prevent the residual heat therein from affecting the efficiency of cooling the water circulation pump 4. The surface of the water circulation pump 4 is cooled by the heat conducting sleeve 96 in cooperation with the heat dissipation fins in contact therewith. At the same time, the air flow blown out by the fan 92 passes through between the heat dissipation fins, quickly drying the moisture accumulated in the dead corner between the motor of the water circulation pump 4 and the heat dissipation fins, thereby avoiding corrosion to the water circulation pump 4, extending the service life of the water circulation pump 4, and thus reducing energy consumption.
