DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0031] See also Figures 1 to 4 The utility model is an automatic water replenishment device for a water tank of a chiller, comprising a water tank body 1 and a water pump 101 installed at the center of an outer wall of one side thereof, a fixing plate 102 is installed at a corner of the inner wall of the water tank body 1, a guide frame 103 is installed on one side of the inner wall of the fixing plate 102, an upper induction sheet 105 and a lower induction sheet 106 are slidably installed on the upper and lower parts of the inner part of the guide frame 103, and a floating block 104 is hoisted between the opposite end surfaces of the upper induction sheet 105 and the lower induction sheet 106.

[0032] Specifically, the water inlet end of the water pump 101 is connected to the external water pipe 1011 through a pipe joint, the water outlet end of the water pump 101 is connected to the delivery pipe 1012 through a pipe joint, the other end of the delivery pipe 1012 is connected to the water inlet pipe 1013 through a pipe joint, and the other end of the water inlet pipe 1013 is arranged above the outer wall of one side of the water tank body 1, and guide grooves 1031 are provided at the upper and lower front and rear ends of the outer wall of one side of the guide frame 103, and a water hole 1032 is provided at the center position of the outer wall of the other side of the guide frame 103. A connecting rope 1041 is fixedly connected to the center position of the top of the floating block 104, and the top end of the connecting rope 1041 is fixed to the center position of the outer wall of the fixing column 1042. The two ends of the fixing column 1042 are respectively fixed on the outer walls of both sides of the guide frame 103, and a guide hole 1051 is provided at the center position of the upper surface of the upper sensor plate 105.

[0033] Furthermore, the fixing plate 102 can be installed on the inner wall of the water tank body 1 by fixing bolts, and the guide frame 103 can be installed on the inner wall of the fixing plate 102 by fixing bolts. The floating block 104 is located between the upper sensor plate 105 and the lower sensor plate 106. The floating block 104 will touch the upper sensor plate 105 or the lower sensor plate 106 according to the floating water level, thereby realizing the monitoring of the water level and controlling the water pump 101 to collect external water source. The pipe joint plays the role of pipeline connection. The water pump 101 draws external water source and then automatically adds water to the inside of the water tank body 1 through the delivery pipe 1012 and the water inlet pipe 1013. The water level inside the guide frame 103 can be made the same as the water level inside the water tank body 1 through the water hole 1032. The floating block 104 is connected and fixed to the fixing column 1042 by using the connecting rope 1041, wherein the connecting rope 1041 can pass through the guide hole 1051 on the surface of the upper sensor plate 105.

[0034] The operation process of this embodiment is as follows: when the water level of the water tank body 1 drops, the float 104 will drop along with the water level, and the float 104 will drop to contact with the lower sensor sheet 106 located in the guide frame 103, triggering a signal to send out information, and the water pump 101 starts to pump water through the external water pipe 1011, and then the water is transported by the delivery pipe 1012 to input the water from the water inlet pipe 1013 into the water tank body 1. During the water adding process, the float 104 of the water tank body 1 will rise along with the water level and will contact with the upper sensor sheet 105 located at the top to trigger a signal. At this time, the water pump 101 stops adding water, so that automatic water adding can be achieved, which improves efficiency and prevents safety accidents. Specific embodiment 2

[0036] See also Figure 4 and 5 On the basis of the specific embodiment 1, what is different from the first embodiment is that: an adjustment component 2 is provided, the adjustment component 2 includes an inner mounting plate 201 and a motor 203 mounted on the inner side thereof, the output shaft of the motor 203 passes through the bearing on the end face of one side of the inner mounting plate 201 and is connected to the threaded rod 2031 through a coupling, which solves the problem that the water level height of the water tank in most existing chillers cannot be adjusted accordingly according to demand, thereby affecting the scope of application.

[0037] Specifically, the other end of the threaded rod 2031 passes through the threaded hole at the center position of the end face of one side of the moving block 204 and is connected to the bearing on the inner wall of the outer mounting plate 202. The end faces of one side of the inner mounting plate 201 and the outer mounting plate 202 are fixed on the outer wall of the guide frame 103. The front and rear ends of the inner wall of the moving block 204 are fixedly connected with connecting rods 2041. The other end of the connecting rod 2041 passes through the guide groove 1031 and is connected to the end faces of one side of the adjacent upper sensor plate 105 and the lower sensor plate 106.

[0038] Furthermore, the operation of the motor 203 can drive the threaded rod 2031 to rotate through the coupling, and the external thread on the outer wall of the threaded rod 2031 is meshed and connected with the internal thread in the wall of the threaded hole on the end face of the moving block 204, playing the role of connecting transmission. Therefore, when the threaded rod 2031 rotates, it will drive the moving block 204 to move, and then the connecting rod 2041 will drive the upper sensor plate 105 and the lower sensor plate 106 to move.

[0039] The operation process of this embodiment is: start the motor 203 in the upper and lower groups of adjustment components 2, and the output shaft of the motor 203 rotates to drive the threaded rod 2031 to rotate under the action of the coupling, and the external thread on the outer wall of the threaded rod 2031 is meshed and connected with the internal thread in the wall of the threaded hole on the end face of the moving block 204. Therefore, when the threaded rod 2031 rotates, it will drive the moving block 204 to move upward or downward, and the moving block 204 will drive the connecting rod 2041 to move, and make the upper and lower sensing plates 105 and 106 above and below the guide frame 103 move, so that the height position of the upper and lower sensing plates 105 and 106 inside the water tank body 1 can be adjusted, and then the water level height in the water tank body 1 can be changed to adapt to different situations. It has a wide range of applications. In order to avoid problems caused by long-term use, this device can be removed for maintenance.
