[0042] Referring to Figure 1 , the circulating water pool 3 is generally designed as an open type, and the water outlet 32 is provided through the pool wall 31 of the circulating water pool 3, and the water outlet 32 is communicated with the condenser, the oil cooler and the cooling water pipe of the air cooler of the turbine unit through a pipeline. In order to simplify the view, Figure 1 , only the structure of the circulating water pool 3 is shown, and the structure of the turbine unit is not shown.

[0043] Such open type circulating water pool 3 is easy to cause different degrees of blockage of the cooling water pipe during use, and the examination shows that the weeds, leaves and snail sundries fall into the circulating water pool 3 and are carried by the water flow to the cooling water pipe, which causes different degrees of blockage of the cooling water pipe, and further causes the heat exchange efficiency of the unit to decrease, which has a large safety hazard.

[0044] In order to solve the problem of blockage of the cooling water pipe, at present, a filtering device is usually installed at the water outlet 32 in the circulating water pool 3, so as to filter the cooling water transported to the cooling water pipe through the water outlet 32, and avoid the weeds, leaves and snail sundries from entering the cooling water pipe. However, since the water outlet 32 is located below the liquid level and close to the bottom of the circulating water pool 3, when the filtering device is installed, the turbine unit must be stopped and the cooling water in the circulating water pool 3 must be discharged, so that the installation efficiency is low and the installation cost is high.

[0045] In order to improve the installation efficiency of the filtering device and reduce the installation cost, referring to Figure 2 , the present application provides a circulating water pool water outlet filtering device, which comprises a filtering unit 1 and a supporting unit 2, the filtering unit 1 is used for abutting against the inner surface of the pool wall 31 of the circulating water pool 3 and covering the water outlet 32 on the pool wall 31, and the supporting unit 2 is connected with the upper end of the filtering unit 1 and is used for supporting on the top of the pool wall 31.

[0046] Referring to Figure 2For simplifying the view, only part of the pool wall 31 of the circulating pool 3 is shown in the figure, wherein the left side of the pool wall 31 is outside of the circulating pool 3, and the right side of the pool wall 31 is inside of the circulating pool 3. The filtering unit 1 is used to tightly adhere to the inner surface of the pool wall 31 and cover the water outlet 32, and then filter the cooling water transported into the cooling water pipe through the water outlet 32, so as to intercept the sundries such as weeds, leaves and snails, and then avoid the sundries such as weeds, leaves and snails in the circulating pool 3 from entering the cooling water pipe to block the cooling water pipe, thereby solving the problem that the open circulating pool is easy to block the cooling water pipe in use. The supporting unit 2 is connected to the upper end of the filtering unit 1 and is used to support the top of the pool wall 31, so that the filtering unit 1 can be hung on the pool wall 31, and the whole filtering device is convenient to install.

[0047] The installation process of the circulating pool water outlet filtering device provided by the embodiment of the application is as follows: the whole filtering device is hoisted to the upper side of the circulating pool 3 by using hoisting equipment, the hoisting equipment is controlled to lower the filtering unit 1 into the circulating pool 3 until the supporting unit 2 is adjacent to the top of the pool wall 31, then the position of the filtering unit 1 is adjusted by the operator standing on the top of the pool wall 31, so that the filtering unit 1 covers the water outlet 32 and tightly adheres to the inner surface of the pool wall 31, then the hoisting equipment is controlled to continue lowering the filtering unit 1 and supporting the supporting unit 2 on the top of the pool wall 31.

[0048] The circulating pool water outlet filtering device provided by the embodiment of the application can support the supporting unit 2 on the top of the pool wall 31, and then hang the filtering unit 1 on the inner surface of the pool wall 31 when installing, so that the online installation of the whole filtering device can be realized, and the circulating unit does not need to be stopped, and the cooling water in the circulating pool does not need to be drained, thereby improving the installation efficiency and reducing the installation cost.

[0049] In some embodiments, referring to Figure 2 , the filtering unit 1 comprises a vertical frame 11 and a filtering assembly 12, the upper end of the vertical frame 11 is connected with the supporting unit 2, the vertical frame 11 is annular and tightly adheres to the inner surface of the pool wall 31, the water outlet 32 is located in the vertical frame 11, and the edge of the filtering assembly 12 is connected with the vertical frame 11 along the circumferential direction of the vertical frame 11.

[0050] The vertical frame 11 can be a circular frame, a trapezoidal frame, a parallelogram frame, a rectangular frame, a square frame, etc. For example, referring to Figure 3The vertical frame 11 is a rectangular frame formed by two vertically arranged vertical rods 111 and two horizontally arranged horizontal rods 112, and the upper horizontal rod 112 is fixedly connected with the supporting unit 2. The vertical rods 111 and the horizontal rods 112 can be connected by bolts or welding. The vertical rods 111 and the horizontal rods 112 can be made of square tubes or square pipes, or other section steels such as channel steels and I-beams. The edges of the filter assembly 12 are connected with the vertical frame 11 along the circumference of the vertical frame 11, and the cooling water delivered into the cooling water pipe through the water outlet 32 can be filtered by the filter assembly 12 to intercept the sundries such as grass, leaves and snails, so as to avoid the sundries such as grass, leaves and snails in the circulating pool 3 from entering the cooling water pipe and blocking the cooling water pipe.

[0051] The filter assembly 12 can be a filter screen, which can be a stainless steel screen with a size of 8x8 mm. The shape and size of the filter screen are matched with those of the vertical frame 11, and the edges of the filter screen are fixedly connected with the vertical frame 11. In this way, the filter screen can cover the water outlet 32, and the cooling water can be filtered to intercept the sundries such as grass, leaves and snails. Of course, the filter assembly 12 can also be a filter plate provided with a plurality of filter holes.

[0052] In some embodiments, the participants Figure 4 The filter assembly 12 includes an inclined frame 121, an inclined filter window 122, a bottom filter window 123 and a side filter window 124. The upper end of the inclined frame 121 is connected with the vertical frame 11 and inclined downward from the upper end to the lower end away from the vertical frame 11. The inclined filter window 122 covers the inclined frame 121. The lower end of the inclined frame 121 is connected with the lower end of the vertical frame 11 through the bottom filter window 123. The two sides of the inclined frame 121 are respectively connected with the vertical frame 11 and the bottom filter window 123 through the side filter windows 124.

[0053] For example, the inclined frame 121 is a rectangular frame formed by splicing square tubes or square pipes. The upper end of the inclined frame 121 is fixedly connected with the upper end of the vertical frame 11, and the inclined frame 121 and the vertical frame 11 are arranged at an angle. In order to improve the connection strength between the inclined frame 121 and the vertical frame 11, see Figure 2The support rod 13 is connected between the inclined frame 121 and the vertical frame 11. The inclined filter window 122, the bottom filter window 123 and the side filter window 124 each include an outer frame and a filter screen arranged in the outer frame, wherein the filter screen can be a 8x8mm stainless steel screen. The inclined filter window 122 is rectangular, and when the inclined filter window 122 is installed on the inclined frame 121, the inclined filter window 122 can cover the inclined frame 121. The bottom filter window 123 is rectangular, and when the bottom filter window 123 is installed between the lower end of the inclined frame 121 and the lower end of the vertical frame 11, the bottom filter window 123 can cover the rectangular space formed between the lower end of the inclined frame 121 and the lower end of the vertical frame 11. The side filter window 124 is triangular, and when the side filter window 124 is installed between the inclined frame 121, the vertical frame 11 and the bottom filter window 123, the side filter window 124 can cover the triangular space enclosed by the inclined frame 121, the vertical frame 11 and the bottom filter window 123. The inclined filter window 122, the bottom filter window 123 and the side filter window 124 can be connected to the vertical frame 11 or the inclined frame 121 by bolts or other fasteners.

[0054] The filter assembly 12 of the above embodiment increases the filtering area by arranging the inclined filter window 122, the bottom filter window 123 and the side filter window 124, thereby improving the filtering efficiency of the cooling water. By arranging the inclined frame 121 at a certain angle with the vertical frame 11, the center of gravity of the filter assembly 12 has a certain distance in the horizontal direction between the vertical frame 11. When the entire filter device is installed, the filter assembly 12 generates a pressing force on the vertical frame 11 under the action of gravity to press the vertical frame 11 tightly against the pool wall 31, thereby improving the firmness and reliability of the entire filter device after installation.

[0055] In order to facilitate the installation of the inclined filter window 122, in some embodiments, referring to Figure 4 The inclined filter window 122 is slidingly connected to the inclined frame 121, so that the inclined filter window 122 can be pulled out from the upper end of the inclined frame 121. For example, a channel steel is fixed on the inclined frame 121 at both sides of the inclined filter window 122, the groove of the channel steel forms a sliding groove matched with the inclined filter window 122, and both sides of the inclined filter window 122 are arranged in the sliding grooves matched therewith. During installation, the two sides of the lower end of the inclined filter window 122 are inserted into the two sliding grooves respectively, and then the inclined filter window 122 is controlled to move downward. When the inclined filter window 122 is moved into position, the inclined filter window 122 and the inclined frame 121 can be connected together.

[0056] In some embodiments, referring to Figure 5The upper end of the inclined filter window 122 is provided with a anti-disengagement member 125 for supporting on the upper end of the inclined frame 121. Exemplarily, the anti-disengagement member 125 is two, and the two anti-disengagement members 125 are respectively fixed on the two sides of the upper end of the inclined filter window 122. When the inclined filter window 122 is installed on the inclined frame 121, the anti-disengagement member 125 supports on the upper end of the inclined frame 121, preventing the inclined filter window 122 from disengaging from the inclined frame 121, so that it is not necessary to set a connecting structure between the inclined filter window 122 and the inclined frame 121. In order to facilitate pulling the inclined filter window 122, referring to Figure 5 The upper end of the inclined filter window 122 is connected with a pull handle 126.

[0057] One inclined filter window 122 can be set on the inclined frame 121. When the transverse dimension of the inclined frame 121 is large, in order to reduce the size and weight of the inclined filter window 122, in some embodiments, the inclined filter window 122 includes at least two which are arranged in parallel along the horizontal direction. By setting at least two inclined filter windows 122 on the inclined frame 121, the size and weight of each inclined filter window 122 can be reduced, facilitating manufacturing, installation and transportation.

[0058] The filter assembly 12 of the above embodiment, the cooling water is mainly filtered through the inclined filter window 122, and after long-term use, most of the sundries such as weeds, leaves and snails are intercepted on the inclined filter window 122. When there are many sundries on the inclined filter window 122, the inclined filter window 122 can be pulled out upwardly, and the sundries intercepted on the inclined filter window 122 can be cleaned manually. In order to prevent the sundries from falling out of the water outlet 32 during the upward pulling process of the inclined filter window 122, in some embodiments, referring to Figure 5 The lower end of the inclined filter window 122 is provided with an upwardly curved reverse bending portion 127.

[0059] Exemplarily, the included angle between the reverse bending portion 127 and the inclined filter window 122 is 90°, so that a containing cavity can be formed between the reverse bending portion 127 and the inclined filter window 122. When it is necessary to clean the sundries on the inclined filter window 122, during the upward pulling process of the inclined filter window 122, even if the sundries on the inclined filter window 122 fall downwardly, they can only fall into the containing cavity between the reverse bending portion 127 and the inclined filter window 122, avoiding falling into the water outlet 32 and being carried by the water flow to the cooling water pipe to cause the cooling water pipe to be blocked.

[0060] The support unit 2 can include a plurality of hooks for hooking on the top of the pool wall 31. In some embodiments, referring to Figure 6The support unit 2 is a frame structure. For example, the support unit 2 comprises two parallel transverse support rods 21 and two parallel longitudinal support rods 22, and the two ends of the two transverse support rods 21 are connected by the two longitudinal support rods 22. The transverse support rods 21 are provided with through holes for the expansion bolts to pass through. One of the transverse support rods 21 is fixedly connected with the horizontal rod 112 in the vertical frame 11. After the support unit 2 is supported on the top of the pool wall 31, it can be fixedly connected with the pool wall 31 by the expansion bolts.

[0061] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. According to the technical essence of the present application, any simple modification, equivalent replacement and improvement of the above embodiment, etc. still belongs to the protection scope of the technical scheme of the present application within the spirit and principles of the present application.
