Description

Technical Field

[0001] This invention relates to the field of water supply pipeline technology, specifically to an intelligent water supply pipeline gate valve protection device and its construction method. Background Technology

[0002] Intelligent gate valves are advanced valve devices that achieve remote control, real-time monitoring, and fault early warning through integrated computing capabilities. Gate valves are usually shallowly buried underground and are subject to long-term physical impacts (construction vibrations, vehicle crushing, etc.), which can easily lead to damage to their internal structure; moreover, they lack effective anti-theft mechanisms, making them vulnerable to tampering with the water supply system.

[0003] The structure related to the anti-theft function of the intelligent gate valve includes a spherical part, an upper convex ring fixedly installed on the top surface of the spherical part, and an opening / closing shaft inserted into a through hole at the top of the spherical part. The spherical part is hollow and contains a rotatable gate plate. The gate plate is fixedly connected to the bottom end of the opening / closing shaft. The top of the opening / closing shaft has a non-circular (e.g., triangular) locking end, which is inserted into the center of the upper convex ring's inner cavity. The operator uses a special key; this key has a cylindrical structure with an inner cross-section adapted to the locking end's cross-section. The operator inserts the key into the upper convex ring and places it around the locking end; turning the key rotates the opening / closing shaft and the gate plate, thus opening and closing the gate valve. This type of gate valve has a simple structure, the key is easy to counterfeit, and its anti-theft performance is insufficient. Summary of the Invention

[0004] In order to overcome the problem of "insufficient anti-theft performance of existing intelligent gate valves" in the above-mentioned background technology, the present invention provides an intelligent water supply pipeline gate valve protection device and construction method.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an intelligent water supply pipeline gate valve protection device, including a housing and a plug-in post. The housing is disposed around the outer periphery of the gate valve. The housing includes a spherical shell and an upper protrusion disposed on the top surface of the spherical shell. The upper protrusion has a receiving hole in the middle. The plug-in post can be adapted to be inserted into the receiving hole and detachably connected to the upper protruding ring on the upper part of the gate valve.

[0009] As a further optimization of the present invention, the linear actuator is disposed below the first crossbar and is perpendicular to the first upright.

[0010] As a further optimization of the present invention, the top surface of the column is provided with a first receiving groove and the bottom surface is provided with a first receiving cavity; a first partition is provided between the first receiving groove and the first receiving cavity, and a second partition is provided at the bottom end of the first receiving cavity; a touch screen is installed in the first receiving groove, and a central processing unit, a wireless signal transmitter, a vibration sensor and a battery are installed in the first receiving cavity; a recess is provided at the bottom end of the outer wall of the abutment ring, and a humidity sensor is provided in the recess; the touch screen, the wireless signal transmitter, the vibration sensor, the battery, the humidity sensor and the linear driver are all connected to the central processing unit via wired electrical connections.

[0011] As a further optimization of the present invention, the first partition is provided with a first wiring hole; the second partition is provided with a second wiring hole; the column is provided with a third wiring hole; and the support block is provided with a fourth wiring hole.

[0012] As a further optimization of the present invention, the spherical part is fixedly connected to a first tube and a second tube, the first tube having a first flange at its end and the second tube having a second flange at its end; the spherical shell is fixedly connected to a third tube and a fourth tube, the third tube having a third flange at its end and the fourth tube having a fourth flange at its end; the first tube is inserted into the inner cavity of the third tube and the second tube is inserted into the inner cavity of the fourth tube; the first flange and the third flange are fitted together, and the second flange and the fourth flange are fitted together.

[0013] As a further optimization of the present invention, a buffer layer is provided between the spherical part and the spherical shell; a waterproof membrane is provided on the top surface of the upper convex part, and the touch screen is located below the waterproof membrane.

[0014] A construction method for an intelligent water supply pipeline gate valve protection device includes an installation method for the intelligent water supply pipeline gate valve protection device, comprising the following steps: S1, installing the housing on the outside of the gate valve; S2, inserting the plug into the receiving hole and pressing it down so that the hook engages the upper protruding ring; S3, attaching the waterproof membrane to the top surface of the upper protrusion and the top surface of the touch screen; S4, installing the sealing cap on the top of the upper protrusion.

[0015] In summary, the present invention has at least one of the following advantages: (1) The plug-in pin can be fitted onto the outer side and upper part of the upper convex ring, thereby covering the opening and closing shaft located inside the upper convex ring. The plug-in pin includes a column body and an abutment ring fixedly installed at the outer edge of the bottom surface of the column body. The abutment ring can be fitted onto the outer circumference of the upper convex ring. When the abutment ring is fitted onto the outer circumference of the upper convex ring, the column body is located above the upper convex ring, thereby sealing the inner cavity of the upper convex ring to achieve the engagement and protection of the opening and closing shaft; then the user needs to pull out the plug-in pin before using a special key to operate the gate valve.

[0016] (2) The bottom end of the abutment ring can be adapted to the spherical part of the gate valve. When the bottom end of the abutment ring abuts the spherical part, the top surface of the plug and the top surface of the upper convex part are flush, or the top surface of the plug is 3-5 mm lower than the top surface of the upper convex part; then the water thief cannot grab or hook the plug and apply outward pulling force to it (there is a lack of contact surface for applying pulling force); at the same time, the water thief cannot damage the plug by knocking inward, which has an excellent anti-theft effect.

[0017] (3) The plug is connected to the upper convex ring through a locking structure rather than being snapped into the spherical shell. Therefore, when the spherical part and the upper convex ring (due to being hit) sink slightly, the upper convex ring will pull the plug inward. The plug can be inserted further inward to accommodate the empty plug, thus preventing its outer wall from being exposed. Water thieves still cannot grab or hook the plug and apply outward pulling force to it (that is, it is more difficult to pull out the plug in the embedded state, and the anti-theft performance is further improved).

[0018] (4) The storage device is used to record the number of times the vibration sensor is activated, and the central processing unit is used to calculate the activation frequency of the vibration sensor. The wireless signal transmitter transmits the activation frequency data to the peripheral monitoring equipment (such as the monitoring room, mobile phone, etc.). After the user learns the activation frequency, he / she judges whether the location has been knocked and then assesses whether water theft has occurred at this location.

[0019] (5) A drain hole is provided on the bottom surface of the spherical shell. The drain hole is located at the bottom of the outer side wall of the support protrusion. When the gate valve leaks water, the leaked water can be discharged into the inner cavity of the shell through the drain hole. The humidity sensor is used to monitor the humidity data in this invention. The wireless signal transmitter transmits the humidity data to the external monitoring equipment. After the user obtains the humidity data, he or she compares it with the standard data to determine whether the gate valve at this position has leaked water.

[0020] (6) A cavity is provided between the spherical part and the spherical shell. The cavity is filled with a buffer layer. The buffer layer is used to absorb impact energy, thereby reducing vibration damage to the gate valve and isolating it from the low temperature environment. Attached Figure Description

[0023] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows: Reference Figures 1-3 The gate valve 1 includes a spherical portion 11, an upper convex ring 12, an opening / closing shaft 13, and a gate plate 132. The upper convex ring 12 is integrally fixedly mounted on the top surface of the spherical portion 11. The opening / closing shaft 13 is inserted into a through hole at the top of the spherical portion 11 and can rotate about its own axis. The spherical portion 11 has a hollow structure, and the gate plate 132 is fitted into the inner cavity of the spherical portion 11 and can rotate about the axis of the opening / closing shaft 13. The bottom end of the opening / closing shaft 13 is fixedly connected to the gate plate 132 (e.g., by bolts, integral connection, or welding). The top end of the opening / closing shaft 13 has a non-circular (e.g., triangular) snap-fit ​​end 131 (e.g., integrally fixed connection), which is inserted into the center of the inner cavity of the upper convex ring 12. The operator holds a special key; the special key has a cylindrical structure and its inner cavity cross-section is adapted to the cross-section of the snap-fit ​​end 131. The construction workers insert a special key into the upper convex ring 12 and place it around the outer circumference of the locking end 131. Then, turning the key can rotate the opening and closing shaft 13 and the gate plate 132 to realize the opening and closing of the gate valve 1.

[0024] Reference Figure 1 and Figure 4 This embodiment provides an intelligent gate valve protection device for water supply pipelines, including a housing 2 and a plug-in post 3. The housing 2 covers and is disposed around the outer periphery of the gate valve 1. The housing 2 includes a spherical shell 21 and an upper protrusion 22 disposed on the top surface of the spherical shell 21. The spherical shell 21 and the upper protrusion 22 are integrally sealed and fixedly connected. The upper protrusion 22 has a receiving hole 221 in the middle, and the plug-in post 3 can be adapted to be inserted into the receiving hole 221. The bottom end of the plug-in post 3 is detachably connected to the upper protruding ring 12 on the upper part of the gate valve 1.

[0025] Reference Figures 1-6 The plug-in post 3 can be adapted to engage with the outer side and upper part of the upper convex ring 12, thereby covering the opening and closing shaft 13 located inside the upper convex ring 12. The plug-in post 3 includes a post body 31 and an abutment ring 32 fixedly installed at the outer edge of the bottom surface of the post body 31. The abutment ring 32 can be adapted to be fitted around the outer periphery of the upper convex ring 12. When the abutment ring 32 is fitted around the outer periphery of the upper convex ring 12, the post body 31 is located above the upper convex ring 12, thereby sealing the inner cavity of the upper convex ring 12 to achieve engagement and protection of the opening and closing shaft 13; then the user needs to pull out the plug-in post 3 before using a special key to operate (e.g., open or close) the gate valve 1 (gate plate 132). Since water theft is usually achieved by rerouting or diverting the water supply system, and the upstream and downstream gate valves 1 need to be closed before modifying the downstream water supply pipe; therefore, by installing this invention on the outside of all gate valves 1 in the water supply system, the gate valves 1 cannot be closed, thus achieving the anti-theft effect.

[0026] Reference Figures 1-6 The bottom end of the abutment ring 32 can be adapted to abut the spherical part 11 of the gate valve 1. When the bottom end of the abutment ring 32 abuts the spherical part 11, the top surface of the plug 3 is flush with the top surface of the upper protrusion 22, or the top surface of the plug 3 is 3-5 mm lower than the top surface of the upper protrusion 22; then, water thieves cannot grab or hook the plug 3 and apply outward pulling force to it (there is a lack of contact surface for applying pulling force); at the same time, water thieves cannot damage the plug 3 by knocking it inward (because it is necessary to knock the plug 3 until it is displaced in order to break its structure and damage it; while the spherical part 11 applies a supporting force to the abutment ring 32, and the abutment ring 32 applies a supporting force to the main body, thereby avoiding the problem of the plug 3 moving inward when it is knocked, thus further avoiding knock damage and having higher resistance performance).

[0027] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The spherical shell 21 has an abutment protrusion in the middle of the bottom surface of its inner cavity, and the top surface of the abutment protrusion is adapted to the bottom surface of the spherical part 11. When the shell 2 is sleeved and installed outside the gate valve 1, the top surface of the abutment protrusion is adapted to fit and abut against the bottom surface of the spherical part 11. The bottom surface of the inner cavity of the spherical shell 21 applies a supporting force to the spherical part 11 through the supporting protrusion 212, so that the spherical part 11 will not be displaced downwards significantly when facing the impact force from the plug post 3, thereby avoiding the problem of bending damage between the first tube 14 and the spherical part 11, and between the second tube 15 and the spherical part 11.

[0028] Reference Figure 5 The bottom surface of the spherical shell 21 is provided with a drainage hole, which is located at the bottom end of the outer wall of the support protrusion 212. When the gate valve 1 leaks water, the leaked water can be discharged into the inner cavity of the shell 2 through the drainage hole, thereby reducing the corrosion of the shell 2 and the plug post 3.

[0029] Reference Figure 1 A cavity is provided between the spherical part 11 and the spherical shell 21, and a buffer layer 201 is filled in the cavity. The buffer layer 201 is used to absorb impact energy, thereby reducing vibration damage to the gate valve 1. The buffer layer 201 is made of elastic rubber or foam material. The outer wall of the buffer layer 201 is adapted to fit the inner wall of the gate valve 1, and the inner wall of the buffer layer 201 is adapted to fit the outer wall of the spherical part 11. The buffer layer 201 can absorb external impact and isolate the low temperature environment.

[0030] Reference Figures 6-10The plug-in post 3 is equipped with a locking structure, which includes a hook 322, a support block 323, a compression spring 324, and a linear actuator 325. The plug-in post 3 is connected to the upper protruding ring 12 through the locking structure rather than being snapped into the spherical shell 21. Therefore, when the spherical part 11 and the upper protruding ring 12 sink slightly (due to being struck), the upper protruding ring 12 will pull the plug-in post 3 inward. Further inward insertion to accommodate the empty plug-in post 3 can prevent its outer side wall from being exposed. Water thieves still cannot grab or hook the plug-in post 3 and apply outward pulling force to it (that is, it is more difficult to pull out the plug-in post 3 in the embedded state, and the anti-theft performance is further improved).

[0031] Reference Figure 7 , Figure 8 and Figure 11 The hook 322 is capable of moving laterally. The hook 322 includes a first horizontal bar 3221 and a first vertical bar 3222 that are fixedly connected in a U-shape or a 7-shape (e.g., by an integral fixed connection). A lower protrusion 32211 is fixed to the bottom surface of the first horizontal bar 3221 away from the first vertical bar 3222 (e.g., by an integral fixed connection). A hook block 32221 is provided at the bottom end of the side wall of the first vertical bar 3222 near the first horizontal bar 3221 (e.g., by an integral fixed connection). A slot 121 for matching the hook block 32221 is provided on the outer side wall of the upper protruding ring 12. The inner end of the top surface of the hook block 32221 is inclined upward, and the inner end of the top surface of the slot 121 is inclined upward. When the hook 322 is subjected to an upward pulling force, the bottom end of the first upright 3222 will not bend outward, causing the hook block 32221 to fall out of the slot 121. This improves the locking stability between the locking structure and the upper protruding ring 12 and enhances the anti-theft effect.

[0032] Reference Figures 9-12 The support block 323 is integrally disc-shaped and is located at the center of the top of the inner cavity of the abutment ring 32 and is detachably connected to the bottom surface of the column 31 (e.g., detachably connected by bolts for periodic battery replacement). The support block 323 has a horizontal hole 3233 for accommodating the first horizontal bar 3221, which is inserted into the horizontal hole 3233 and can reciprocate laterally; the inner side wall of the abutment ring 32 has a side groove for accommodating the first vertical bar 3222, which is inserted into the side groove and can reciprocate laterally; thereby realizing the engagement and disengagement of the locking structure with the upper protruding ring 12.

[0033] Reference Figures 9-12The lower protrusion 32211 is inserted into the spring groove in the support block 323. The spring groove is located at the bottom surface of the horizontal hole 3233. The horizontal hole 3233 and the spring groove are arranged horizontally and communicate with each other. The compression spring 324 is located in the spring groove and abuts against the lower protrusion 32211. The end of the compression spring 324 away from the abutting ring 32 abuts against the lower protrusion 32211, and the end closer to the abutting ring 32 abuts against the inner end face of the spring groove. The compression spring 324 can push the hook 322 to move laterally inward until the hook block 32221 is engaged with the slot 121, realizing the engagement between the locking structure and the upper protruding ring 12.

[0034] Reference Figures 9-12 The support block 323 has a rectangular hole and a reset hole 3232, which are coaxially arranged and interconnected at their ends; both the rectangular hole and the reset hole 3232 are located below the spring groove. The linear actuator 325 is installed in the rectangular hole of the support block 323 (for example, by bolt fixing or by snap-fit ​​fixing). The output shaft of the linear actuator 325 is inserted into the reset hole 3232 of the support block 323 and can extend outward. When the output shaft extends outward from the reset hole 3232, it can abut against the first upright 3222 and push the first upright 3222 and the hook 322 to move laterally outward until the hook block 32221 is pulled out of the slot 121, realizing the disengagement of the locking structure from the upper protruding ring 12.

[0035] Reference Figures 9-12 The linear actuator 325 is horizontally positioned below the first crossbar 3221, and the linear actuator 325 is vertically positioned with respect to the first upright bar 3222.

[0036] Reference Figures 9-12 The column 31 has a first receiving groove 311 on its top surface and a first receiving cavity 312 on its bottom surface. A touch screen 301 is installed in the first receiving groove 311 (e.g., by adhesive or snap-fit). A central processing unit, a storage device, a wireless signal transmitter, a vibration sensor, and a battery are installed in the first receiving cavity 312 (e.g., by bolt fixing). The bottom end of the outer wall of the abutment ring 32 has a recessed hole, in which a humidity sensor 3202 or a liquid level sensor is installed (e.g., by bolt fixing). The touch screen 301, storage device, wireless signal transmitter, vibration sensor, battery, humidity sensor 3202, and linear driver 325 are all connected to the central processing unit via wired electricity (e.g., wires and / or signal lines).

[0037] Reference Figure 10A first partition 3111 is provided between the first receiving groove 311 and the first receiving cavity 312. The outer edge of the first partition 3111 is integrally fixedly connected to the column 31, thus having excellent impact resistance and sealing performance. If the water thief strikes the top surface of the column 31 until the touch screen 301 breaks, he will further strike the bottom surface of the first receiving groove 311. Therefore, the first partition 3111 needs to have excellent anti-theft performance, that is, excellent impact resistance, to prevent it from being pulled out by pulling force (if the first partition 3111 is pulled out, the central processing unit will be exposed, and the water thief can cut the wire connected to the linear actuator 325 and connect the wire to the self-contained power supply, which can drive the linear actuator 325 to open the locking structure) and to prevent it from sinking and deforming under the impact (protecting the central processing unit, storage, wireless signal transmitter, vibration sensor and battery in the first receiving cavity 312 from impact damage and reducing property loss).

[0038] Reference Figure 9 , Figure 10 and Figure 12 The bottom end of the first receiving cavity 312 is provided with a second partition 3121. The second partition 3121 is detachably connected to the column 31 (for example, by bolt fixing), thereby facilitating the installation of the central processing unit, storage device, wireless signal transmitter, vibration sensor and battery in the first receiving cavity 312.

[0039] Reference Figure 10 The first partition 3111 is provided with a first wiring hole 31111. The two ends of the first wiring hole 31111 are respectively connected to the first receiving groove 311 and the first receiving cavity 312. The wires and / or signal lines connected to the touch screen 301 are inserted into the first wiring hole 31111. The first wiring hole 31111 is provided with waterproof glue to prevent water leakage.

[0040] Reference Figure 10 The second partition 3121 is provided with a second wiring hole 3122. The wires and / or signal lines connected to the linear driver 325 are inserted into the second wiring hole 3122. The second wiring hole 3122 is provided with waterproof glue to prevent water leakage.

[0041] Reference Figure 10 The support block 323 has a fourth wiring hole 3231; the wires and / or signal lines connected to the humidity sensor 3202 or the liquid level sensor are inserted into the fourth wiring hole 3231, and the fourth wiring hole 3231 is filled with waterproof glue to prevent water leakage.

[0042] Reference Figure 13The housing 2 is divided into an upper housing 2001 and a lower housing 2002. The upper housing 2001 and the lower housing 2002 can be interlocked to cover the outer periphery of the gate valve 1, and a sealing ring is provided at the interlocking position to achieve waterproofing. The upper housing 2001 and the lower housing 2002 are fixedly connected at the interlocking position (for example, by an integral fixed connection).

[0043] Reference Figure 1 and Figure 2 The spherical part 11 has a first tube 14 and a second tube 15 fixedly connected to its side wall (e.g., by integral fixed connection or by welding fixed connection). The first tube 14 has a first flange 141 at its end (e.g., by welding fixed connection), and the second tube 15 has a second flange 151 at its end (e.g., by welding fixed connection).

The third tube 23 has a third flange 231 at its end (e.g., by welding fixed connection), and the fourth tube 24 has a fourth flange 241 at its end (e.g., by welding fixed connection).

[0045] Reference Figure 14 The first pipe body 14 is inserted into the inner cavity of the third pipe body 23 and a first sealing ring 232 is pressed between them to prevent water leakage; the second pipe body 15 is inserted into the inner cavity of the fourth pipe body 24 and a second sealing ring 242 is pressed between them to prevent water leakage; the first flange 141 and the third flange 231 are fitted together and detachably connected by bolts; the second flange 151 and the fourth flange 241 are fitted together and detachably connected by bolts.

[0046] Reference Figure 14 The inlet pipe 4 is connected and communicates with the first pipe body 14.
