In addition, the actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Referring to FIGS. 1 and 2, which show a first embodiment of the present invention, 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 the communication member 102; a backflow prevention assembly 200 including a drainage member 201 provided on one side of the communication member 102, a water outflow member 202 provided inside the communication member 102, a blocking member 203 provided on one side of the drainage member 201, and a cleaning member 204 provided on one side of the drainage member 201; The intake member 103 includes an exhaust fan 103b provided above the communication member 102, The drainage member (201) includes an upper cavity (201a) and a lower cavity (201b) provided in the communicating member (102), the lower cavity (201b) being recessed and arc-shaped, and the blocking 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), to provide a cable pit vapor blocking device in an electrical room.

[0022] Specifically, the structural member 101 includes a cable pit body 101a and a trench 101b provided on one side of the cable pit body 101a, The communicating member 102 includes a water inlet pipe 102a provided on one side of the cable pit main 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, and the cable pit, water inlet pipe 102a, backflow prevention pipe 102b, and drain pipe 102c are all provided at positions near the top of one side of the trench 101b, which on the one hand makes it easy to drain water, and on the other hand reduces the possibility of water in the trench 101b flowing back into the cable pit, The intake member 103 includes a mounting bracket 103a provided above the backflow prevention pipe 102b and an exhaust fan 103b provided within the mounting bracket 103a. A ventilation opening is opened above the backflow prevention pipe 102b, and the exhaust fan 103b is attached to the ventilation opening. The provided exhaust fan 103b can absorb and drain steam within the drain pipe 102c and the backflow prevention pipe 102b, thereby reducing the possibility of steam flowing into the cable pit and realizing the function of blocking steam within the trench 101b.

[0023] The operation process is as follows: In use, after the installation of the water inlet pipe 102a, backflow prevention pipe 102b, and drainage pipe 102c is completed, when it is necessary to drain water from the cable pit, the water can be drained through the backflow prevention pipe 102b and the drainage pipe 102c, and an exhaust fan 103b is attached to the upper side of the backflow prevention pipe 102b by means of a mounting bracket 103a, with a ventilation opening opened on the upper side of the backflow prevention pipe 102b. When the fan is started, it absorbs and drains steam from the drainage pipe 102c and the backflow prevention pipe 102b, reducing the possibility of steam flowing into the cable pit and thereby achieving the function of blocking steam from the trench 101b. After the drainage is completed, the installed backflow prevention pipe 102b blocks the water flow in the trench 101b, reducing the possibility of sewage or the like from the trench 101b flowing back into the cable pit.

[0024] Example 2 2 to 5, this embodiment differs from the first embodiment in the following points: The drainage 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 making it easy to restrict the position of the baffle 201g and reducing 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 baffle 201g, respectively, and the tension coil spring 201i is fitted to the baffle 201g. 01g, and the drainage 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 being higher on the left side and lower on the right side, and the arc of the arc-shaped portion 201e extending in the direction of the drainage pipe 102c.In this way, water that flows into the upper cavity 201a can be easily guided into the drainage pipe 102c and finally flow into the trench 101b, thereby improving the drainage efficiency of the upper cavity 201a.

[0025] Specifically, the outflow 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, an outflow pipe 202c provided on one side of the fixed ring 202b, and drainage holes 202d opened on the circumferential surface of the outflow pipe 202c, and the drainage holes 202d are provided in plurality and are distributed at equal angles on the circumferential surface of the outflow pipe 202c, so that the water in the lower cavity 201b passes through the fixed pipe 202a and the drainage holes 202d in sequence to enter the outflow pipe 202c, and finally flows into the drainage pipe 102c to be discharged into the trench 101b, and in the initial state, the stopper 202f is located outside the drainage hole 202d and blocks the drainage hole 202d.

[0026] Preferably, the water outflow member 202 includes a guiding block 202e provided on one side of the water outflow pipe 202c, a stopper 202f slidably provided on the outside of the water outflow pipe 202c, and a return spring 202g provided on one side of the fixing ring 202b, the stopper 202f is provided in an annular shape and slidably distributed on the outside of the water outflow pipe 202c, 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 on the stopper 202f. The flow guide block 202e is provided in a trapezoidal shape, and by providing the flow guide block 202e in a trapezoidal shape, water that has entered the fixed pipe 202a can be easily diverted and diverted to the outside, and after being diverted to the outside of the water outlet pipe 202c, it can enter the inside of the water outlet pipe 202c and be discharged through the drain hole 202d. 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, allowing the water to leak out and be discharged through the drain hole 202d.

[0027] Preferably, the water outflow member 202 further includes a mounting groove 202h opened on one side of the stopper 202f, a plug 202i slidably arranged in the mounting groove 202h, and a compression spring 202j arranged inside the mounting groove 202h, wherein the plug 202i is shaped like a semicircular block, 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; when the stopper 202f slides to the outside of the drainage hole 202d, the plug 202i is subjected to the restoring force of the compression spring 202j and is driven to slide toward the drainage hole 202d to further block the drainage hole 202d, thereby reducing the possibility of water in the trench 101b flowing back through the water outflow pipe 202c and improving the backflow prevention effect of the water outflow pipe 202c.

[0028] All other structures are the same as those in the first embodiment.

[0029] The operation process is as follows: during drainage, if the water flow entering the lower cavity 201b is small, the water flows into the outflow pipe 202c and is guided to the outside of the outflow pipe 202c by the guide block 202e, and then presses the stopper 202f on the outside of the outflow pipe 202c. At this time, the plug 202i inside the stopper 202f is in the shape of a semicircular block, so that the plug 202i comes into contact with the side wall of the outflow hole 202d and is pressed by the side wall of the outflow hole 202d and forced into the mounting groove 202h, after which the stopper 202f is released from its position. 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 outflow hole 202d. The water flows through the outflow hole 202d and into the outflow pipe 202c, thereby completing the drainage of the water from the cable pit.

[0030] When the water flow is large, part of it is discharged through the water outlet pipe 202c, while the other part continues to accumulate in the lower cavity 201b. When the water level is too high and accumulates, it impacts the baffle 201g above the drain groove 201d, causing the baffle 201g to slide upward, exposing the drain groove 201d and allowing the excess water to be discharged through the upper cavity 201a. This allows the device to automatically discharge the water according to the amount of water in the cable pit.

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

[0032] Example 3 1 to 9, this embodiment differs from the above-mentioned embodiments in the following respects: The intake member 103 includes a mounting bracket 103a provided above the backflow prevention pipe 102b and an exhaust fan 103b provided within the mounting bracket 103a, a ventilation opening is provided above the backflow prevention pipe 102b, and the exhaust fan 103b is attached to the ventilation opening, and the exhaust fan 103b absorbs and drains steam within the drain pipe 102c and the backflow prevention pipe 102b, thereby reducing the possibility of steam flowing into the cable pit. , thereby realizing the function of blocking steam in the trench 101b. The blocking member 203 includes a connecting rod 203a provided on one side of the baffle 201g and a hollow drainage ball 203b provided at one end of the connecting rod 203a. The hollow drainage ball 203b extends into the lower cavity 201b. The lower cavity 201b is concave and arc-shaped, low in the middle and high on both sides. The height of the water inlet pipe 102a is higher than that of the water outlet pipe 202c, and the height of the water inlet pipe 102a is higher than that of the water outlet pipe 202c. The hollow drain ball 203b is slidable, and does not contact the drain groove 201d. When drainage is required, the hollow drain ball 203b slides upward following the baffle 201g, but does not contact the drain groove 201d and cannot seal the drain groove 201d. Since the lower cavity 201b is recessed and arc-shaped, some water remains inside the lower cavity 201b after drainage is completed. At this time, the baffle 201g is affected by gravity. The hollow drain ball 203b is received and driven to slide downward to extend into the remaining residual water, raising the liquid level of the residual water inside and making the liquid level higher than the height of the water outlet pipe 202c.Since the height of the water inlet pipe 102a is higher than the height of the water outlet pipe 202c, the liquid level of the residual water will not become higher than the water inlet pipe 102a, thereby realizing a liquid seal in the water outlet pipe 202c and reducing the possibility of steam entering the cable pit through the water 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 during liquid sealing, thereby enhancing the liquid sealing effect, and the provided seal groove 203d and seal ring 203e enable the baffle 201g to enhance its sealing effect after falling.

[0034] The cleaning member 204 further includes a sleeve 204a provided on one side of the connecting rod 203a, an expansion 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 expansion block 204b, and a scraper 204e provided on one side of the arc-shaped bar 204d. The scraper 204e contacts the inner wall of the drain groove 201d, and both the upper and lower sides of the scraper 204e When the baffle 201g slides into the drain groove 201d, the scraper 204e has slopes on both sides, so that the opening of the drain groove 201d presses against the slopes of the scraper 204e, and the scraper 204e is pressed by the restoring force of the main spring 204c to come into contact with the drain groove 201d. The arc-shaped bar 204d and the scraper 204e clean the side walls of the drain groove 201d while the baffle 201g moves up and down, reducing the possibility of dirty water flowing through the drain groove 201d for a long time and clogging the drain groove 201d.

[0035] The other structures are the same as those in the second embodiment.

[0036] The operation process is as follows: When in use, when the exhaust fan 103b is turned on, it absorbs and drains the steam in the drain pipe 102c and the backflow prevention pipe 102b, reducing the possibility of steam flowing into the cable pit and thereby achieving the function of blocking steam in the trench 101b; because the lower cavity 201b is concave and arc-shaped, after drainage is complete, some residual water will remain inside the lower cavity 201b; at this time, under the influence of gravity, the baffle 201g drives the hollow drain ball 203b 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 water outlet pipe 202c; because the height of the water inlet pipe 102a is higher than that of the water outlet pipe 202c, the liquid level of the residual water will not be higher than that of the water inlet pipe 102a, thereby achieving a liquid seal in the water outlet pipe 202c and reducing the possibility of steam entering the cable pit through the water outlet pipe 202c.

[0037] Also, 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 groove 201d presses against the slopes of the scraper 204e. The scraper 204e is pressed by the restoring force of the main spring 204c to come into contact with the drain groove 201d, scraping and cleaning the drain groove 201d. This improves the cleaning effect and reduces the possibility of dirty water flowing through the drain groove 201d for a long time, clogging the drain groove 201d and affecting the drainage effect.
