[0022] Embodiment:

[0023] Please refer to Figures 1-3As shown in the figure, a water pre-cooling device for a data center computer room includes a cushion rod 1 and a locking sleeve 5. The cushion rod 1 is fixed to the ground. There are two cushion rods 1 arranged in parallel. A condenser housing 2 is fixed to the tops of the two cushion rods 1. An end cover 201 is fixed to the front end of the condenser housing 2. A refrigerant inlet and outlet pipe 202 penetrates through the surface of the end cover 201. Two cooling water inlet and outlet pipes 203 are arranged on the top of the condenser housing 2. The cooling water inlet and outlet pipes 203 are in an L shape. The two cooling water inlet and outlet pipes 203 communicate with the two ends inside the condenser housing 2 respectively, so as to facilitate the passage of cold water into the condenser housing 2 and flow out through another pipe. The ends of the two cooling water inlet and outlet pipes 203 are arranged parallel to each other up and down. A support rod 204 is vertically fixed to the top of the condenser housing 2. The support rod 204 supports the end of the upper cooling water inlet and outlet pipe 203 to ensure the stability of the upper cooling water inlet and outlet pipe 203. A fixing plate 205 is arranged between the two cooling water inlet and outlet pipes 203. An adjusting screw 206 is screwed through the surface of the fixing plate 205. An adjusting docking cylinder 3 is slidably installed at the end of the cooling water inlet and outlet pipe 203. A connecting plate 301 is arranged at the rear end between the two adjusting docking cylinders 3. Rotate the adjusting screw 206 to control the position of the connecting plate 301, and then control the expansion and contraction of the upper and lower two adjusting docking cylinders 3 to control the position of their ends. The end of the adjusting screw 206 is rotatably installed on the connecting plate 301.

[0024] Please refer to Figures 1-3 As shown in the figure, an annular groove 302 is formed at the rear end inside the adjusting docking cylinder 3. A clamp 304 is installed inside the annular groove 302. A sealing ring 306 is arranged inside the clamp 304. The inner side of the sealing ring 306 is in contact with the surface of the cooling water inlet and outlet pipe 203 to improve the sealing performance between the adjusting docking cylinder 3 and the cooling water inlet and outlet pipe 203. A notch is formed below the clamp 304. Extension plates 305 are arranged downward on both sides of the notch of the clamp 304. Installation cavities 303 are formed at both ends inside the connecting plate 301. The installation cavities 303 are located at the bottom of the annular groove 302 and communicate with the inside of the annular groove 302. Both extension plates 305 are located inside the installation cavities 303. When the two extension plates 305 approach each other, the clamp 304 can be tightened, thereby increasing the extrusion of the inner sealing ring 306 and improving the sealing performance. On the contrary, when moving relatively, the extrusion of the extension plates 305 can be released to reduce the extrusion of the sealing ring 306 and improve the smoothness of the movement of the adjusting docking cylinder 3.

[0025] Please refer to Figure 3As shown, a double-threaded rod 307 is installed inside the installation cavity 303 through bearings. The double-threaded rod 307 penetrates through one side surface of the connecting plate 301, and a knob is provided at the end of the double-threaded rod 307. Movable blocks 308 are symmetrically screwed onto the surface of the double-threaded rod 307. The two movable blocks 308 are respectively screwed onto different thread surfaces. A push rod 309 is vertically arranged on the upper surface of the movable block 308. The two push rods 309 are respectively placed outside the two extension plates 305. By rotating the external knob to control the rotation of the double-threaded rod 307, the movement of the two movable blocks 308 is then controlled to squeeze the extension plates 305, so as to realize the tightening work of the sealing ring 306.

[0026] Please refer to Figure 1 and Figure 4 As shown, movable seats 4 are symmetrically welded to both sides of the bottom of the condenser housing 2. The bottom of the movable seat 4 is slidably installed on the cushion rod 1. Positioning grooves 101 are evenly formed inside the cushion rod 1. Fixed cylinders 401 are provided on one side of the two movable seats 4 close to each other. The movable seat 4 can slide along the surface of the cushion rod 1, thereby adjusting the movement of the condenser housing 2. The locking sleeve 5 is placed between the two cushion rods 1.

A control anti-slip surface 501 is provided on the surface of the locking sleeve 5 to facilitate the rotation operation of the locking sleeve 5. Adjusting distance screws 502 are symmetrically screwed onto both ends of the control anti-slip surface 501. The threads on the surfaces of the two adjusting distance screws 502 are opposite. A sliding rod 503 is provided at the end of the adjusting distance screw 502 away from the locking sleeve 5. When the locking sleeve 5 rotates, the two adjusting distance screws 502 can be controlled to approach or move away from each other simultaneously.

[0027] Among them, the end of the sliding rod 503 away from the adjusting distance screw 502 slides inside the fixed cylinder 401. The size of the end of the sliding rod 503 is adapted to the inside of the positioning groove 101. Through the cooperation of the two, the fixing of the two movable seats 4 on both sides is controlled.

[0028] Working principle: The rotating locking sleeve 5 can control two distance-adjusting screws 502 to approach or move away from each other simultaneously, so as to control whether the end of the sliding rod 503 cooperates with the corresponding positioning groove 101. During use, the two are used to fix the moving seat 4, so as to fix the position of the condenser housing 2, and quickly contact the limit, so as to facilitate the sliding of the condenser housing 2 along the track of the cushion rod 1 to adjust its position. During docking, the pipeline and the adjustment docking cylinder 3 are used to flush cold water into the condenser housing 2 and flow out through another adjustment docking cylinder 3. During docking, the adjusting screw 206 can be rotated to control the position of the connecting plate 301, and then the distance between the two adjustment docking cylinders 3 can be controlled simultaneously to facilitate the docking work. After the adjustment is completed, the double threaded rod 307 is rotated to control the two moving blocks 308 to approach each other, so as to drive the push rod 309 to clamp the extension plate 305, so that the clamp 304 is tightened to squeeze the sealing ring 306, improving the sealing performance of the connection between the adjustment docking cylinder 3 and the cooling water inlet and outlet pipe 203 and preventing water leakage.
