Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1 and 2, an external environment cooling installation system of a diesel generator set includes a cooling water tank 1, a pumping mechanism 2 and a circulating water tank 3;
an exhaust pipe of the diesel generator set extends into the cooling water tank 1, a drain pipe 11 is arranged at the upper end of the cooling water tank 1, the drain pipe 11 is used for discharging redundant water in the cooling water tank 1 into the circulating water pool 3, and a water inlet pipe 12 is arranged at the lower end of the cooling water tank 1;
the water pumping mechanism 2 comprises a working chamber 21, a partition 22 and a cylinder 23;
a partition 22 is arranged in the working chamber 21, the partition 22 divides the working chamber 21 into a piston chamber 211 and a water chamber 212, a first one-way valve 4 and a second one-way valve 5 are arranged on the water chamber 212, the first one-way valve 4 is connected with the water inlet pipe 12, and the second one-way valve 5 is connected with the circulating water tank 3 through a pipeline;
the cylinder 23 is provided on a piston chamber 211, and a piston of the cylinder 23 is reciprocable in the piston chamber 211.
The working principle is as follows: because diesel generating set's blast pipe stretches into in cooling water tank 1, consequently diesel generating set is at the during operation, and the heat that the blast pipe released can be absorbed by the water in cooling water tank 1. Then, by activating the cylinder 23 of the pumping mechanism 2, the piston of the cylinder 23 reciprocates in the piston chamber 211, and the diaphragm 22 is moved back and forth in the working chamber 21 in accordance with the movement of the piston of the cylinder 23 in order to keep the air density in the working chamber 21 constant. Therefore, the cold water in the circulating water tank 3 enters the water chamber 212 through the second one-way valve 5, then enters the water inlet pipe 12 from the water chamber 212 through the first one-way valve 4, and then enters the cooling water tank 1. Since the density of the hot water is less than that of the cold water, the drain pipe 11 is disposed at the upper end of the cooling water tank 1, and when the cold water in the circulation water tank 3 enters the cooling water tank 1, the hot water absorbing the heat released from the exhaust pipe enters the drain pipe 11 and is finally discharged into the circulation water tank 3 through the drain pipe 11.
From the above description, the beneficial effects of the present invention are: the exhaust pipe of the diesel generator set extends into the cooling water tank 1, and the water in the cooling water tank 1 absorbs the heat released by the exhaust pipe. Then, the water pumping mechanism 2 pumps the ice-cold water in the circulating water tank 3 into the cooling water tank 1, and the hot water in the cooling water tank 1 enters the circulating water tank 3 through the water discharge pipe 11, so that the influence of an exhaust pipe of the diesel generator set on the external temperature is reduced.
Further, a plurality of stoppers 213 are disposed in the working chamber 21, and the stoppers 213 surround the spacers 22.
Further, the space surrounded by the limiting block 213 is an ellipsoid.
As is apparent from the above description, in order to ensure that the air density in the working chamber 21 is constant, when the working chamber 21 is inflated back and forth with the movement of the piston of the cylinder 23, in order to prevent excessive inflation of the diaphragm 22, which may lead to accelerated strain on the diaphragm 22, particularly on the joint between the diaphragm 22 and the working chamber 21, a plurality of stoppers 213 are provided in the working chamber 21, and the stoppers 213 surround the diaphragm 22, which can limit the inflation range of the diaphragm 22.
Referring to fig. 3, a convex hull 221 is further formed at the connection position of the diaphragm 22 and the working chamber 21.
From the above description, it can be seen that the joint between the diaphragm 22 and the working chamber 21 is the most vulnerable during the operation of the diaphragm 22, and the convex hull 221 is raised at the joint, so that the service life of the diaphragm 22 can be prolonged.
Referring to fig. 4, further, a sealing mechanism 6 is arranged at a connection position of an exhaust pipe of the diesel generator set and the cooling water tank 1, and the sealing mechanism 6 includes a shaft sleeve 61, a sealing seat 62 and a plug ring 63;
the shaft sleeve 61 is sleeved on an exhaust pipe of the diesel generator set;
the sealing seat 62 is sleeved on the shaft sleeve 61 and is in threaded connection with the cooling water tank 1, and a plugging groove which is open towards the inner direction of the cooling water tank 1 is formed in the contact end of the sealing seat 62 and the shaft sleeve 61;
one side of the plug ring 63 can be plugged into the plugging groove.
As can be seen from the above description, in order to avoid the water in the cooling water tank 1 flowing out along the exhaust pipe of the diesel generator set, a sealing mechanism 6 is provided at the connection between the cooling water tank 1 and the exhaust pipe of the diesel generator set. The shaft sleeve 61 is sleeved on the exhaust pipe to protect the exhaust pipe, then the sealing seat 62 is sleeved on the shaft sleeve 61 and is in threaded connection with the cooling water tank 1, and then one side of the plug ring 63 is plugged into the plugging groove of the sealing seat 62, so that a sealing effect is achieved.
Referring to fig. 5, a ring of blocking wall 611 is further protruded from an outer side wall of the sleeve 61, and one side of the blocking wall 611 abuts against the other side of the plug ring 63.
As can be seen from the above description, a ring of blocking wall 611 is protruded on the outer side wall of the shaft sleeve 61, and the sealing performance of the sealing mechanism 6 can be further improved by abutting one side of the blocking wall 611 with the other side of the plug ring 63.
Further, a plug connector 7 is disposed on one side of the blocking wall 611, and a plug groove 8 adapted to the plug connector 7 is disposed on the other side of the plug ring 63.
As can be seen from the above description, the plug connector 7 is disposed on the one side of the blocking wall 611, and the plug groove 8 adapted to the plug connector 7 is disposed on the other side of the plug ring 63, so that the plug connector 7 is inserted into the plug groove 8, and the sealing effect between the blocking wall 611 and the plug ring 63 can be further improved.
Further, the plug ring 63 is a tapered ring with a gradually decreasing outer diameter, one side of the plug ring 63 is a small-diameter end of the tapered ring, and the other side of the plug ring 63 is a large-diameter end of the tapered ring.
As can be seen from the above description, one end of the plug ring 63 is the small diameter end of the conical ring, which facilitates the plug ring 63 to be plugged into the plugging groove of the sealing seat 62.
Referring to fig. 1, a plurality of showers 9 are further disposed on the drain pipe 11, and the showers 9 are located above the circulating water tank 3.
As can be seen from the above description, after the water in the cooling water tank 1 flows into the drain pipe 11, the water is divided into a plurality of minute water columns by the shower head 9 and then enters the circulating water tank 3. This can increase the contact area between water and air, and improve the cooling efficiency of water.
Further, a plurality of liquid nitrogen bottles 10 are arranged in the circulating water tank 3.
As can be seen from the above description, nitrogen is often used as a protective gas in industrial processes due to its chemical inertness. When the liquid nitrogen bottle 10 is used in a factory, the liquid nitrogen bottle 10 can be placed in the circulating water tank 3, and the temperature of the surrounding environment can be reduced when the liquid nitrogen is output due to the low temperature of the liquid nitrogen, so that the cooling efficiency of water can be further improved.
