[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.
[0003] Most of the existing hydraulic pressure stabilizers for cooling towers are connected to the water inlet pipe of the cooling tower by welding, but the welding steps are cumbersome, and when the water inlet pipe needs to be replaced, the entire device needs to be replaced. Therefore, some of them use threaded connections, but due to the large impact force of water, vibration may occur for a long time, so that the interface becomes loose after being used for a period of time. Therefore, a hydraulic pressure stabilizer for cooling tower is proposed to solve the problems raised by the background technology. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a hydraulic pressure stabilizer for a cooling tower, which solves the problem that the interface between the hydraulic pressure stabilizer flange and the water inlet pipe becomes loose after long-term use.

[0006] Preferably, the clamping block is completely retracted into the water inlet pipe in an initial state, and the inner wall of the sliding block is fixedly connected to the bottom end of the clamping block.
[0007] Preferably, the top of the clamping block is in a cone shape, and when the sliding block slides toward the flange direction, the clamping block is driven to move, and the top of the clamping block is clamped into the inside of the conical circular groove.
[0008] Preferably, one side of the inclined block is in an inclined surface shape, and when the clamping block moves in the flange, the inclined block is squeezed to shrink into the inner part of the outer cylinder.
[0009] Preferably, after the clamping block is clamped with the conical circular groove, the inclined block is located inside the clamping groove.
[0010] Preferably, one end of the pull rod passes through the outer wall of the outer cylinder and extends to the outside thereof, and two ends of the second spring are fixedly connected to the outer cylinder and the inclined block respectively.
[0011] Preferably, the groove is in the shape of an arc-shaped notch, and the cross-section of the groove is larger than the cross-section of the block.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model enables the device to fix the water inlet pipe and prevent it from loosening through the cooperation between the flange, the water inlet pipe, the clamping block and the inclined block. When the flange is threadedly connected to the water inlet pipe, the slider is slid in the direction of the flange to drive the clamping block to move to the inside of the flange.

The flange 1 is provided with a circular groove 10, and a groove 11 is provided on one side of the flange 1 close to the water inlet pipe 2. A slider 12 is movably sleeved on the outside of the flange 1. The slider 12 is slid toward the direction of the flange 1 to drive the block 3 to move to the inside of the flange 1. While the block 3 moves, the inclined block 7 is squeezed to shrink to the inside of the outer cylinder 6. When the top of the block 3 is engaged with the conical circular groove 10, the inclined block 7 is reset and stuck into the inside of the groove 5 under the action of the elastic force of the second spring 9, so that the entire block 3 is locked inside the flange 1, thereby fixing the position of the water inlet pipe 2.
[0021] like Figures 1 to 4 As shown, the block 3 is completely retracted into the water inlet pipe 2 in the initial state, the inner wall of the slider 12 is fixedly connected to the bottom end of the block 3, the top of the block 3 is conical, and when the slider 12 slides toward the flange 1, it drives the block 3 to move and makes the top of it stuck in the conical groove 10. One side of the inclined block 7 is inclined, and when the block 3 moves in the flange 1, the inclined block 7 is squeezed and retracted into the outer cylinder 6; the top of the block 3 is conical, and its function is that when (3) rotates and has a slight deviation from (10), the top of (3) will contact the side of (10), thereby correcting the position of (3) and making the top of (3) completely stuck in the interior of (10).
[0022] like Figures 1 to 4 As shown, after the block 3 is engaged with the tapered circular groove 10, the inclined block 7 is located inside the groove 5, one end of the pull rod 8 penetrates the outer wall of the outer cylinder 6 and extends to the outside thereof, the two ends of the second spring 9 are fixedly connected to the outer cylinder 6 and the inclined block 7 respectively, the groove 11 is in the shape of an arc notch, and the cross-section of the groove 11 is larger than the cross-section of the block 3; one end of the pull rod 8 is located outside the flange 1, and its function is that when the water inlet pipe 2 needs to be replaced, the pull rod 8 is pulled to drive the inclined block 7 to completely shrink to the inside of the outer cylinder 6, thereby releasing the engagement with the block 3, and then the slider 12 is slid in the reverse direction to drive the block 3 to shrink to the inside of the flange 1, and finally the water inlet pipe 2 is rotated in the reverse direction to release the threaded connection with the flange 1, and the cross-section of the groove 11 is larger than that of the block 3, which is used to facilitate the block 3 to be inserted into the inside of the flange 1, and because the block 3 is engaged with the tapered circular groove 10, the gap generated by the groove 11 when the block 3 rotates is made up.
[0023] The working principle and use process of the utility model are as follows: the water inlet pipe 2 is rotated to make it threadedly connected with the flange 1, and then the water inlet pipe 2 and the flange 1 are attached to form a seal.

When the clamping block 3 moves in the flange 1, the inclined block 7 is squeezed to shrink to the inside of the outer cylinder 6. When the top of the clamping block 3 is clamped with the conical circular groove 10, the inclined block 7 is reset under the action of the elastic force of the second spring 9 and is clamped into the inside of the clamping groove 5, so that the clamping block 3 is clamped into the inside of the flange 1, and the position of the water inlet pipe 2 is fixed.
