[0019] Next, the "one embodiment" or "embodiment" referred to in this specification refers to specific features, configurations or characteristics that may be included in at least one implementation form of the present invention. The descriptions of "in one embodiment" appearing in different parts of this specification do not all refer to the same embodiment, nor are they exclusive embodiments that are independent or selectively mutually exclusive with other embodiments.

[0020] Subsequently, the present invention will be described in detail while referring to the schematic diagrams. However, when detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the structure of the components are not enlarged partially in a general proportion. The above schematic diagrams are only examples and should not be used to limit the protection scope of the present invention here. Also, in actual creation, the three-dimensional space dimensions of length, width and depth should be included.

[0021] Example 1 Referring to Figures 1 and 2, which represent a first embodiment of the present invention, the present invention is described as follows: A structural assembly 100 including a structural member 101, a communication member 102 provided on one side of the structural member 101, and an intake member 103 provided on one side of the communication member 102, wherein the intake member 103 is used to extract steam from within the communication member 102, The backflow prevention assembly 200 includes a drain member 201 provided on one side of the communication member 102, a water outlet member 202 provided inside the communication member 102, a shut-off member 203 provided on one side of the drain member 201, and a cleaning member 204 provided on one side of the drain member 201, The intake member 103 includes an exhaust fan 103b provided on the upper side of the communication member 102. The present invention provides a cable pit steam shutoff device for an electrical room, wherein the drainage member 201 includes an upper cavity 201a and a lower cavity 201b provided within the communication member 102, the lower cavity 201b being recessed and provided in an arc shape, and the shutoff member 203 includes a hollow drainage ball slidably provided on one side of the drainage member 201, the hollow drainage ball being slidably provided within the lower cavity 201b.

[0022] Specifically, the structural member 101 includes the cable pit body 101a and the trench 101b provided on one side of the cable pit body 101a. The connecting member 102 includes a water inlet pipe 102a provided on one side of the cable pit body 101a, a backflow prevention pipe 102b provided on one side of the water inlet pipe 102a, and a drain pipe 102c provided on one side of the backflow prevention pipe 102b. The cable pit, water inlet pipe 102a, backflow prevention pipe 102b, and drain pipe 102c are all provided in an upper position on one side of the trench 101b, which allows for easy drainage on the one hand and reduces the possibility of water in the trench 101b backflowing into the cable pit on the other hand. The intake member 103 includes a mounting bracket 103a provided on the upper side of the backflow prevention pipe 102b and an exhaust fan 103b provided inside the mounting bracket 103a. A ventilation opening is provided on the upper side of the backflow prevention pipe 102b, and the exhaust fan 103b is attached to the ventilation opening. The exhaust fan 103b can absorb and drain steam from the drain pipe 102c and the backflow prevention pipe 102b, thereby reducing the possibility of steam flowing into the cable pit and achieving the function of blocking steam from entering the trench 101b.

[0023] The operation process is as follows: When in use, after completing the installation of the water inlet pipe 102a, backflow prevention pipe 102b, and drain pipe 102c, if it is necessary to drain the water from the cable pit, the water can be drained through the backflow prevention pipe 102b and drain pipe 102c. An exhaust fan 103b is attached to the upper side of the backflow prevention pipe 102b by a mounting bracket 103a, and a ventilation opening is provided on the upper side of the backflow prevention pipe 102b. When the fan is started, it absorbs and drains the steam in the drain pipe 102c and backflow prevention pipe 102b, reducing the possibility of steam flowing into the cable pit, thereby achieving the function of blocking steam in the trench 101b. After drainage is complete, the installed backflow prevention pipe 102b blocks and shuts off the water flow in the trench 101b, reducing the possibility of sewage etc. in the trench 101b backflowing into the cable pit.

[0024] Example 2 Referring to Figures 2 to 5, this embodiment differs from the first embodiment in the following respects. The drain member 201 includes a slide bar 201f provided on the upper side of the partition plate 201c, a baffle 201g slidably provided on the upper side of the slide bar 201f, a retaining cover 201h provided on the upper side of the slide bar 201f, and a tension coil spring 201i fitted to the outside of the slide bar 201f. The retaining cover 201h facilitates positional restriction of the baffle 201g and reduces the possibility of the baffle 201g falling off. Both ends of the tension coil spring 201i are connected to the side walls of the retaining cover 201h and the side walls of the baffle 201g, respectively. Used to perform a reset drive on 01g, the drain member 201 further includes a partition plate 201c provided inside the backflow prevention pipe 102b, a drainage groove 201d opened on one side of the partition plate 201c, and an arc-shaped portion 201e provided on one side of the upper cavity 201a. The height of the arc-shaped portion 201e is set so that the left side is higher and the right side is lower, and the arc of the arc-shaped portion 201e extends in the direction of the drain pipe 102c. In this way, water flowing into the upper cavity 201a can be easily guided into the drain pipe 102c and finally into the trench 101b, thereby increasing the drainage efficiency of the upper cavity 201a.

[0025] Specifically, the water outlet member 202 includes a fixed pipe 202a provided on one side of the backflow prevention pipe 102b, a fixed ring 202b provided on the outside of the fixed pipe 202a, a water outlet pipe 202c provided on one side of the fixed ring 202b, and drainage holes 202d opened on the circumferential surface of the water outlet pipe 202c. Multiple drainage holes 202d are provided and distributed at equal angles on the circumferential surface of the water outlet pipe 202c. Water from the lower cavity 201b passes sequentially through the fixed pipe 202a and drainage holes 202d into the water outlet pipe 202c, and finally flows into the drainage pipe 102c and is discharged into the trench 101b. In the initial state, the stopper 202f is located on the outside of the drainage holes 202d and blocks the drainage holes 202d.

[0026] Preferably, the water outlet member 202 includes a flow guide block 202e provided on one side of the water outlet pipe 202c, a stopper 202f slidably provided on the outside of the water outlet pipe 202c, and a return spring 202g provided on one side of the fixing ring 202b, wherein the stopper 202f is provided in an annular shape and slidably distributed on the outside of the water outlet pipe 202c, and both ends of the return spring 202g are connected to the side wall of the stopper 202f and the side wall of the fixing ring 202b, respectively, and the return spring 202g performs a reset drive relative to the stopper 202f. Used for this purpose, the flow guide block 202e is provided in the shape of a truncated circle. By providing the flow guide block 202e in the shape of a truncated circle, water that enters the fixed pipe 202a can be easily diverted and directed to the outside, and after being directed to the outside of the outlet pipe 202c, it can enter the inside of the outlet pipe 202c through the drain hole 202d and be discharged. At the same time, the provided flow guide block 202e increases the impact force of the water flow on the stopper 202f, driving the stopper 202f to slide, and allowing the water to leak out from the drain hole 202d and be drained.

[0027] Preferably, the water outlet member 202 further includes a mounting groove 202h opened on one side of the stopper 202f, a plug 202i slidably provided within the mounting groove 202h, and a compression spring 202j provided inside the mounting groove 202h, wherein the plug 202i is provided in a semicircular block shape, and both ends of the compression spring 202j are connected to the side wall of the plug 202i and the inner wall of the mounting groove 202h, respectively, and when the stopper 202f slides to the outside of the drain hole 202d, the plug 202i receives the restorative force of the compression spring 202j and is driven to slide in the direction of the drain hole 202d to further close the drain hole 202d, thereby reducing the possibility of water in the trench 101b flowing back through the water outlet pipe 202c and enhancing the backflow prevention effect of the water outlet pipe 202c.

[0028] All other structural features are the same as in Example 1.

[0029] The operation process is as follows: When draining, if the water flow entering the lower cavity 201b is small, the water flow enters the outlet pipe 202c, is guided to the outside of the outlet pipe 202c by the flow guide block 202e, and subsequently presses against the stopper 202f on the outside of the outlet pipe 202c. At this time, since the plug 202i inside the stopper 202f is provided in the shape of a semicircular block, the plug 202i comes into contact with the side wall of the drain hole 202d, is pressed by the side wall of the drain hole 202d and pushed into the mounting groove 202h, after which the fixing of the stopper 202f is released. At this time, the stopper 202f is driven by the impact force of the water flow and slides toward the fixing ring 202b, completely opening the drain hole 202d, and the water flow passes through the drain hole 202d and enters the outlet pipe 202c, thereby completing the drainage of water from the cable pit.

[0030] If the water flow is large, some of it is discharged through the outlet pipe 202c, while the rest continues to accumulate in the lower cavity 201b. If it accumulates too high, it strikes the baffle 201g above the drain channel 201d, driving the baffle 201g to slide upward, exposing the drain channel 201d, allowing the excess water to be discharged through the upper cavity 201a. In this way, the device can automatically discharge water according to the amount of water in the cable pit.

[0031] After the water in the cable pit has been drained, the baffle 201g is reset by gravity and the restorative force of the tension coil spring 201i, resealing the drain channel 201d. At the same time, the stopper 202f on the outside of the outlet pipe 202c is driven by the restorative force of the return spring 202g to perform a reset slide, sliding again to the outside of the drain hole 202d and blocking it. Also, the plug 202i slides again into the drain hole 202d by the restorative force of the compression spring 202j, thereby completely sealing the backflow prevention pipe 102b and reducing the possibility of sewage in the trench 101b backflowing into the cable pit.

[0032] Example 3 Referring to Figures 1 to 9, this embodiment differs from the above embodiments in the following respects. The intake member 103 includes a mounting bracket 103a provided on the upper side of the backflow prevention pipe 102b and an exhaust fan 103b provided inside the mounting bracket 103a. A ventilation opening is provided on the upper side of the backflow prevention pipe 102b, and the exhaust fan 103b is attached to the ventilation opening. The exhaust fan 103b absorbs and drains steam in the drain pipe 102c and the backflow prevention pipe 102b, thereby reducing the possibility of steam flowing into the cable pit. This provides a function to block steam in the trench 101b, and the blocking member 203 includes a connecting rod 203a provided on one side of the baffle 201g and a hollow drain ball 203b provided at one end of the connecting rod 203a, the hollow drain ball 203b extends into the lower cavity 201b, the lower cavity 201b is recessed and provided in an arc shape, lower in the middle and higher on both sides, and the height of the water inlet pipe 102a is higher than the height of the outlet pipe 202c, and is also The hollow drain ball 203b is provided to be rideable and does not come into contact with the drain channel 201d. When drainage is needed, the hollow drain ball 203b slides upward following the baffle 201g, but does not come into contact with the drain channel 201d and cannot seal the drain channel 201d. Because the lower cavity 201b is recessed and provided in an arc shape, some water remains inside the lower cavity 201b after drainage is complete. At this time, the baffle 201g is affected by gravity. The hollow drain ball 203b is driven to slide downward and extend into the remaining residual water, raising the liquid level of the residual water inside so that the liquid level can be higher than the height of the outlet pipe 202c. Since the height of the water inlet pipe 102a is higher than the height of the outlet pipe 202c, the liquid level of the residual water will not be higher than the water inlet pipe 102a, thereby achieving liquid sealing of the outlet pipe 202c and reducing the possibility of steam entering the cable pit through the outlet pipe 202c.

[0033] Specifically, the blocking member 203 further includes a bend portion 203c provided on one side of the fixed pipe 202a, a seal groove 203d opened on the upper side of the partition plate 201c, and a seal ring 203e provided on the lower side of the baffle 201g. The provided bend portion 203c allows it to extend more effectively into the residual water when liquid is sealed, thereby enhancing the liquid sealing effect. The provided seal groove 203d and seal ring 203e allow the baffle 201g to enhance its sealing effect after it has fallen.

[0034] Furthermore, the cleaning member 204 includes a sleeve 204a provided on one side of the connecting rod 203a, a telescopic block 204b slidably provided on one side of the sleeve 204a, and a main spring 204c provided inside the sleeve 204a. The cleaning member 204 further includes an arc-shaped bar 204d provided on one side of the telescopic block 204b, and a scraper 204e provided on one side of the arc-shaped bar 204d, the scraper 204e contacting the inner wall of the drainage channel 201d, and both the upper and lower sides of the scraper 204e. A slope is provided on the side, and when it slides into the drainage channel 201d, the slope is provided on both sides of the scraper 204e, so the opening of the drainage channel 201d presses against the slope of the scraper 204e, and the scraper 204e is pressed by the restoring force of the main spring 204c and comes into contact with the drainage channel 201d. The provided arc-shaped bar 204d and scraper 204e clean the side walls of the drainage channel 201d while the baffle 201g moves up and down, reducing the possibility of wastewater flowing through the drainage channel 201d for a long time and blocking the drainage channel 201d.

[0035] All other structural features are the same as in Example 2.

[0036] The operation process is as follows: When in use, activating the exhaust fan 103b absorbs and drains steam from the drain pipe 102c and backflow prevention pipe 102b, reducing the possibility of steam flowing into the cable pit, thereby blocking steam from entering the trench 101b. The lower cavity 201b is recessed and provided in an arc shape, so that after drainage is complete, some residual water remains inside the lower cavity 201b. At this time, the baffle 201g is affected by gravity and drives the hollow drain ball 203b to slide downward and extend into the residual water, raising the liquid level of the residual water inside. The liquid level can be made higher than the height of the outlet pipe 202c. Since the height of the water inlet pipe 102a is higher than the height of the outlet pipe 202c, the liquid level of the residual water will not be higher than the water inlet pipe 102a. This achieves liquid sealing of the outlet pipe 202c, reducing the possibility of steam entering the cable pit through the outlet pipe 202c.

[0037] Furthermore, during drainage, when the baffle 201g moves up and down, it drives the scraper 204e to move up and down. The scraper 204e has slopes on both sides, and the opening of the drain channel 201d presses against the slopes of the scraper 204e. As a result, the scraper 204e is pressed by the restorative force of the main spring 204c and comes into contact with the drain channel 201d, scraping and cleaning the drain channel 201d. This enhances the cleaning effect and reduces the possibility of wastewater flowing through the drain channel 201d for a long time, blocking it and affecting the drainage effect.
